-**KST4Contest** (auch bekannt als *PraktiKST*) ist ein Java-basierter Chat-Client für den [ON4KST-Chat](http://www.on4kst.info/chat/), der speziell für den Contest-Betrieb auf den VHF/UHF/SHF-Bändern (144 MHz und aufwärts) entwickelt wurde.
+KST4Contest ist ein Desktop-Client für den [ON4KST-Chat](https://www.on4kst.org/chat/login.php), der für den Contest-Betrieb auf den VHF-, UHF- und SHF-Bändern entwickelt wurde. Er verbindet Chat, Stationsauswahl, Sked-Planung, Aircraft-Scatter-Daten und die Anbindung an weitere Programme in einer gemeinsamen Arbeitsoberfläche.

-Entwickelt von **DO5AMF (Marc Fröhlich)**, Operator bei DM5M.
+Entwickelt wird KST4Contest von **DO5AMF (Marc Fröhlich)**, Operator bei DM5M und (seit Mai 2025) **DN9APW (Philipp Wagner)**. Der Quellcode ist öffentlich auf [GitHub](https://github.com/praktimarc/kst4contest) verfügbar.
+
+---
+
+## Wozu braucht man einen eigenen ON4KST-Client?
+
+Der ON4KST-Chat liefert während eines Contests eine große Menge an Informationen: aktive Stationen, Locator, Frequenzen, Sked-Anfragen und Hinweise auf aktuelle Aktivität. Das eigentliche Problem besteht nicht darin, diese Daten zu sehen. Man muss daraus rechtzeitig die nächste sinnvolle Verbindung ableiten.
+
+KST4Contest wertet die verfügbaren Informationen aus, ordnet sie und stellt sie in einem contestgerechten Arbeitsablauf dar. Dabei werden unter anderem Antennenrichtung, Entfernung, bekannte Bänder und Frequenzen, bereits gearbeitete Stationen, Chat-Aktivität und Aircraft-Scatter-Zeiten berücksichtigt.
+
+Das Programm entscheidet jedoch nicht, welches QSO tatsächlich möglich ist. Der Prioritätsscore, die AP-Timeline und die verschiedenen Hervorhebungen sind Entscheidungshilfen. Die endgültige Beurteilung bleibt beim Operator – schon deshalb, weil auch ein recht überzeugender Computerbildschirm noch keine Funkverbindung herstellt.
+
+---
+
+## Was KST4Contest im Contest unterstützt
+
+- **Chat beobachten und einordnen:** KST4Contest kann zwei ON4KST-Chat-Kategorien gleichzeitig darstellen. Nachrichten, Frequenzangaben und bekannte Bandaktivitäten werden den jeweiligen Stationen zugeordnet.
+
+- **Relevante Stationen herausfiltern:** Richtungs-, Entfernungs-, Worked- und NOT-QRV-Filter reduzieren die Benutzerliste auf die Stationen, die für den aktuellen Betriebszustand tatsächlich interessant sind.
+
+- **Kandidaten priorisieren:** Das Score-System bewertet aktive Chatmember anhand mehrerer bekannter Kriterien. Die derzeit relevantesten Kandidaten erscheinen zusätzlich in einer eigenen Prioritätsliste.
+
+- **Skeds vorbereiten und im Blick behalten:** Sked-Erinnerungen, automatische Vorwarnungen und die AP-Timeline helfen dabei, vereinbarte Verbindungen nicht zwischen Chat, Log und laufendem CQ-Betrieb zu verlieren.
+
+- **Aircraft Scatter einbeziehen:** Über die AirScout-Schnittstelle werden geeignete Flugzeuge und erwartete Reflexionszeiten in die Stationsbewertung und Zeitplanung übernommen.
+
+- **Log und Funkstation anbinden:** KST4Contest synchronisiert gearbeitete Stationen und Frequenzinformationen mit unterstützten Logprogrammen. Zusätzlich stehen Schnittstellen zu Win-Test, PSTRotator und ein integrierter DX-Cluster-Server zur Verfügung.
+
+- **Stationen und Funkwege darstellen:** Die Stationskarte zeigt aktive Chatmember, Locator-Felder, Antennenrichtungen und den Weg zur ausgewählten Station. Für ausgewählte Verbindungen kann außerdem ein Geländeprofil berechnet werden.
+
+Die Funktionen greifen ineinander. Eine erkannte Frequenz kann beispielsweise einem aktiven Band zugeordnet werden, der Worked-Status stammt aus dem Log, Aircraft-Scatter-Daten ergänzen die zeitliche Bewertung und der daraus berechnete Score beeinflusst die Prioritätsliste. Fehlende oder veraltete Eingangsdaten können deshalb auch das Ergebnis beeinflussen.
+
+---
+
+## Voraussetzungen
+
+Für die Anmeldung ist ein registrierter ON4KST-Account erforderlich. Registrierung und Login sind über die [offizielle ON4KST-Anmeldeseite](https://www.on4kst.org/chat/login.php) erreichbar.
+
+Die offizielle Sprache im ON4KST-Chat ist Englisch. Das gilt auch für Nachrichten an Stationen aus dem eigenen Land. Übliche Amateurfunk-Abkürzungen wie `pse`, `agn`, `qrg`, `dir`, `rrr`, `tnx` oder `73` sind dabei normal und meistens erheblich schneller als ausformulierte Prosa.
+
+Download, unterstützte Betriebssysteme und Installationswege sind im Kapitel [Installation](de-Installation) beschrieben.
+
+---
+
+## Versionsstand dieses Handbuchs
+
+Dieses Handbuch beschreibt die stabile Version **v1.41.1**.
+
+Funktionen oder Änderungen, die nur im aktuellen Entwicklungsstand enthalten sind, werden ausdrücklich als **Nightly / v1.42** gekennzeichnet. Fehlt eine solche Kennzeichnung, bezieht sich die Beschreibung auf die stabile Version.
+
+- [Aktuelle stabile Version herunterladen](https://github.com/praktimarc/kst4contest/releases/latest)
+- [Nightly-Builds und automatisierte Builds](https://github.com/praktimarc/kst4contest/actions)
+- [Versionsgeschichte](de-Changelog)
+
+Für einen Contest ist grundsätzlich die stabile Version zu empfehlen. Nightly-Builds enthalten neuere Korrekturen und Funktionen, können sich aber zwischen zwei Builds verändern. Sie sind sinnvoll, wenn eine bestimmte Änderung getestet werden soll – weniger sinnvoll ist der erste Versuch zehn Minuten vor Contestbeginn.

 > 🇬🇧 [English version](en-Installation) | 🇩🇪 Du liest gerade die deutsche Version

-## Voraussetzungen
+KST4Contest wird für Windows, Linux und macOS als fertiges Programmpaket bereitgestellt. Für die offiziellen Release-Pakete muss Java nicht separat installiert werden: Die benötigte Java-Laufzeitumgebung ist bereits enthalten.

-Es wird eine Mindestauflösung von 1200px mal 720px empfohlen
+Benötigt werden damit im Wesentlichen ein unterstütztes Betriebssystem, eine Internetverbindung und ein ON4KST-Account. Das klingt zunächst überschaubar – und ist es normalerweise auch.
+
+## Voraussetzungen

 ### ON4KST-Account

-Um den Chat zu nutzen, ist ein registrierter Account beim ON4KST-Chat-Dienst erforderlich:
+KST4Contest ist ein eigenständiger Client für den ON4KST-Chat, ersetzt aber nicht den dazugehörigen Benutzeraccount.

- Registrierung unter: http://www.on4kst.info/chat/register.php
+Falls noch kein Account vorhanden ist, kann er über die offizielle ON4KST-Seite angelegt werden:

-### Verhaltensregeln im Chat
+- [ON4KST-Anmeldung und Registrierung](https://www.on4kst.org/chat/login.php)

-Die offizielle Sprache im ON4KST-Chat ist **Englisch**. Auch bei Kommunikation mit Stationen aus dem eigenen Land bitte Englisch verwenden. Übliche HAM-Abkürzungen (agn, dir, pse, rrr, tnx, 73 …) sind gang und gäbe.
+ON4KST gibt Englisch als gemeinsame Sprache im Chat vor. Das gilt auch dann, wenn beide beteiligten Stationen dieselbe Muttersprache sprechen. Im Contestbetrieb werden häufig die üblichen Amateurfunk-Abkürzungen wie `pse`, `agn`, `qrg`, `dir`, `rrr`, `tnx` oder `73` verwendet.

-### Persönliche Nachrichten
+Die eigentliche Bedienung des Chats und das Senden persönlicher Nachrichten werden im Kapitel zur Benutzeroberfläche beschrieben. Für die Installation ist zunächst nur wichtig, dass der Account funktioniert.

-Um eine Privatnachricht an eine andere Station zu senden, immer folgendes Format verwenden:
+### Bildschirmgröße

-```
-/CQ RUFZEICHEN Nachrichtentext
-```
+Eine nutzbare Bildschirmfläche von ungefähr **1200 × 720 Pixeln** oder mehr wird empfohlen.

-Beispiel: `/CQ DL5ASG pse sked 144.205?`
+KST4Contest passt das Hauptfenster automatisch an die verfügbare Fläche des primären Bildschirms an. Das Programm kann deshalb auch auf kleineren Bildschirmen gestartet werden. Weniger Platz bleibt allerdings weniger Platz: In diesem Fall können nicht alle Tabellen, Filter und Zusatzinformationen gleichzeitig in sinnvoller Größe dargestellt werden.

-Bei starkem Chat-Verkehr (5–6 Nachrichten pro Sekunde im Contest) gehen öffentliche Nachrichten, die an ein bestimmtes Rufzeichen gerichtet sind, leicht unter. KST4Contest fängt solche Nachrichten aber auch dann ab, wenn sie fälschlicherweise öffentlich gepostet werden (siehe [Funktionen – PM-Abfang](Funktionen#catching-personal-messages)).
+### Java
+
+Für die fertigen Pakete aus den [GitHub Releases](https://github.com/praktimarc/kst4contest/releases/latest) ist keine separate Java-Installation erforderlich. Die benötigte Laufzeitumgebung wird zusammen mit KST4Contest ausgeliefert.
+
+Eine Java-Entwicklungsumgebung wird nur benötigt, wenn KST4Contest selbst aus dem Quellcode gebaut werden soll. Bei den AUR-Paketen `kst4contest` und `kst4contest-git` werden Java 21 und Maven als Build-Abhängigkeiten durch den Paketmanager berücksichtigt.
+
+---
+
+## Stable, Beta oder Nightly?
+
+KST4Contest wird in drei Entwicklungsständen bereitgestellt:
+
+| Kanal | Geeignet für | Einordnung |
+|---|---|---|
+| **Stable** | Normaler Contestbetrieb | Veröffentlichte und für den regulären Einsatz vorgesehene Version |
+| **Beta** | Gezielte Tests vor einem Stable-Release | Vorabversion mit weitgehend festgelegtem Funktionsumfang |
+| **Nightly** | Frühe Tests neuer Funktionen | Aktueller Entwicklungsstand aus dem `main`-Branch |
+
+Für den normalen Einsatz wird die **Stable-Version** empfohlen.
+
+Beta- und Nightly-Versionen können Funktionen enthalten, die im Stable-Release noch nicht verfügbar sind. Sie können aber ebenso unfertige Bedienabläufe, geänderte Einstellungen oder neue Fehler enthalten. Das ist kein ungewöhnlicher Defekt im Veröffentlichungsverfahren, sondern der Zweck eines Entwicklungskanals.
+
+Wenn in diesem Manual eine Funktion ausdrücklich mit **Nightly** gekennzeichnet ist, gehört sie noch nicht zwingend zum aktuellen Stable-Release.

 ---

 ## Download

-### Windows
+Die aktuelle Stable-Version ist hier verfügbar:

-Die aktuelle Version kann als ZIP-Datei heruntergeladen werden:
+- [Aktuelles KST4Contest-Release](https://github.com/praktimarc/kst4contest/releases/latest)

-**https://github.com/praktimarc/kst4contest/releases/latest**
+Die Release-Seite enthält die Programmpakete sowie die deutschen und englischen PDF-Handbücher.

-Der Dateiname hat das Format `praktiKST-v<Versionsnummer>-windows-x64.zip `.
+### Welches Paket wird benötigt?

-### Linux
-
-Mehrere Paketformate stehen auf der Releases-Seite zur Verfügung:
-
-**https://github.com/praktimarc/kst4contest/releases/latest**
-
-| Format | Dateiname | Geeignet für |
+| Betriebssystem | Paket | Typischer Dateiname |
 |---|---|---|
-| AppImage | `KST4Contest-v<Version>-linux-x86_64.AppImage` | Alle Distributionen |
-| Debian-Paket | `KST4Contest-v<Version>-debian-amd64.deb` | Debian, Ubuntu, Linux Mint, … |
-| RPM-Paket | `KST4Contest-v<Version>-fedora-x86_64.rpm` | Fedora, RHEL, openSUSE, … |

+Starte das Programm nicht direkt aus der noch komprimierten ZIP-Datei. KST4Contest besteht aus mehreren Dateien und einer mitgelieferten Laufzeitumgebung. Windows kann diese Struktur nur zuverlässig verwenden, wenn das Archiv vorher vollständig entpackt wurde.

-### Linux
+Die Programmeinstellungen befinden sich nicht im entpackten Programmordner, sondern im Benutzerverzeichnis:

-Die Einstellungen werden immer unter `~/.praktikst/preferences.xml` gespeichert.
+```text
+%USERPROFILE%\.praktiKST\preferences.xml
+```

-#### AppImage
+Dadurch können neue Programmversionen in einen anderen Ordner entpackt werden, ohne dass die vorhandenen Einstellungen verloren gehen.

-1. AppImage herunterladen.
-2. Ausführbar machen: `chmod +x KST4Contest-v<Version>-linux-x86_64.AppImage`
-3. Starten.
+---

-#### Debian / Ubuntu
+## Installation unter Linux
+
+Unter Linux stehen mehrere Paketformate zur Verfügung. Welches davon sinnvoll ist, hängt weniger von KST4Contest als von der verwendeten Distribution und der gewünschten Update-Methode ab.
+
+| Installationsart | Sinnvoll, wenn … |
+|---|---|
+| **Flatpak** | Updates zentral verwaltet werden sollen und Flatpak bereits verwendet wird |
+| **AppImage** | KST4Contest ohne Installation als einzelne portable Datei gestartet werden soll |
+| **DEB/RPM** | die Paketverwaltung der Distribution verwendet werden soll |
+| **Arch-Paket/AUR** | Arch Linux, Manjaro oder EndeavourOS eingesetzt wird |
+
+### Flatpak
+
+Flatpak ist für die meisten Linux-Anwender der einfachste Weg, KST4Contest installiert und aktualisierbar zu halten. Das KST4Contest-Repository ist GPG-signiert und enthält die Kanäle Stable, Beta und Nightly.
+
+#### Stable über die Release-Datei installieren
+
+Lade `de.x08.KST4Contest.flatpakref` aus dem aktuellen Release herunter und öffne die Datei mit der Softwareverwaltung der verwendeten Desktop-Umgebung.
+
+Alternativ kann sie im Terminal installiert werden:
+
+```bash
+flatpak install ./de.x08.KST4Contest.flatpakref
+```
+
+#### KST4Contest-Repository hinzufügen
+
+Das Repository muss nur einmal hinzugefügt werden:
+
+```bash
+flatpak remote-add --if-not-exists kst4contest \
+https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
+```
+
+Anschließend kann die Stable-Version installiert werden:
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//stable
+```
+
+#### Beta installieren
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//beta
+```
+
+#### Nightly installieren
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//nightly
+```
+
+KST4Contest verwendet für alle drei Kanäle dieselbe App-ID. Eine parallele Installation mehrerer KST4Contest-Kanäle ist deshalb nicht vorgesehen.
+
+Zum Wechsel von Stable auf Nightly beispielsweise:
+
+```bash
+flatpak uninstall de.x08.KST4Contest//stable
+flatpak install kst4contest de.x08.KST4Contest//nightly
+```
+
+Die persönlichen Einstellungen im Verzeichnis `~/.praktiKST` werden dabei nicht automatisch gelöscht.
+
+Installierte Flatpak-Anwendungen können mit folgendem Befehl aktualisiert werden:
+
+```bash
+flatpak update de.x08.KST4Contest
+```
+
+Je nach Desktop-Umgebung kann die grafische Softwareverwaltung verfügbare Flatpak-Updates ebenfalls anzeigen oder automatisch installieren. Der Befehl `flatpak update` selbst führt das Update aus; er verspricht nicht, irgendwann von allein vorbeizukommen.
+
+### AppImage
+
+Das AppImage benötigt keine klassische Installation.
+
+1. Lade `KST4Contest-v<Version>-linux-x86_64.AppImage` herunter.
+2. Öffne ein Terminal im Download-Verzeichnis.
+3. Mache die Datei ausführbar:
+
+```bash
+chmod +x KST4Contest-v<Version>-linux-x86_64.AppImage
+```
+
+4. Starte KST4Contest:
+
+```bash
+./KST4Contest-v<Version>-linux-x86_64.AppImage
+```
+
+Das AppImage kann anschließend an einen anderen Ort verschoben werden, beispielsweise nach `~/Applications`.
+
+### Debian und Ubuntu
+
+Installiere das DEB-Paket mit:

 ```bash
 sudo apt install ./KST4Contest-v<Version>-debian-amd64.deb
 ```

-Oder die `.deb`-Datei im Dateimanager doppelklicken.
+Alternativ kann die Datei in einer grafischen Paketverwaltung geöffnet werden.

-#### Fedora / RHEL
+### Fedora und kompatible RPM-Systeme
+
+Installiere das RPM-Paket mit:

 ```bash
 sudo dnf install ./KST4Contest-v<Version>-fedora-x86_64.rpm
 ```

-#### Arch Linux
+### Arch Linux: fertiges Release-Paket
+
+Das aus dem GitHub Release heruntergeladene Arch-Paket kann direkt installiert werden:

 ```bash
 sudo pacman -U KST4Contest-v<Version>-archlinux-x86_64.pkg.tar.zst
 ```

-#### Flatpak
+### Arch Linux: Installation über den AUR
+
+Im AUR stehen drei Varianten bereit:
+
+| Paket | Inhalt |
+|---|---|
+| [`kst4contest-bin`](https://aur.archlinux.org/packages/kst4contest-bin) | Vorgefertigtes Paket des aktuellen Stable-Releases |
+| [`kst4contest`](https://aur.archlinux.org/packages/kst4contest) | Stable-Release, das lokal aus dem Quellcode gebaut wird |
+| [`kst4contest-git`](https://aur.archlinux.org/packages/kst4contest-git) | Aktueller Entwicklungsstand aus dem `main`-Branch |
+
+Für die meisten Anwender ist `kst4contest-bin` die naheliegende Variante:

-Die Datei `de.x08.KST4Contest.flatpakref` aus dem [aktuellen Release](https://github.com/praktimarc/kst4contest/releases/latest) herunterladen und öffnen, oder:
 ```bash
-flatpak install de.x08.KST4Contest.flatpakref
+yay -S kst4contest-bin
 ```

-Oder den Remote manuell hinzufügen (empfohlen für Nightly/Beta-Zugriff):
+Stable aus dem Quellcode bauen:
+
 ```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-flatpak install kst4contest de.x08.KST4Contest
+yay -S kst4contest
 ```

-#### Flatpak-Kanäle (nightly / beta / stable)
+Aktuellen Entwicklungsstand bauen:

-Das Flatpak-Repository enthält drei Kanäle, die alle im selben Remote liegen:
+```bash
+yay -S kst4contest-git
+```

-| Kanal | Inhalt | Wird gebaut bei |
+Die drei Pakete stellen dieselbe Anwendung bereit und sind deshalb als gegenseitige Konflikte definiert. Installiere nur eine Variante gleichzeitig.
+
+AUR-Updates werden berücksichtigt, wenn der verwendete AUR-Helper nach Paketaktualisierungen sucht, beispielsweise mit:
+
+```bash
+yay -Syu
+```
+
+Sie erfolgen nicht allein deshalb automatisch, weil das Paket aus dem AUR stammt.
+
+---
+
+## Installation unter macOS
+
+> **Best-Effort-Support:** Die macOS-Pakete werden zusammen mit den übrigen Releases gebaut, aber nicht in demselben Umfang getestet wie die Windows- und Linux-Versionen. Rückmeldungen sind willkommen; eine vollständig geprüfte Unterstützung aller macOS-Versionen und Hardwarevarianten kann derzeit jedoch nicht zugesagt werden.
+
+Für Apple-Silicon-Macs wird das Paket mit `arm64` benötigt. Für Intel-Macs ist das Paket mit `x86_64` vorgesehen.
+
+1. Lade die passende DMG-Datei herunter.
+2. Öffne die DMG-Datei.
+3. Ziehe `KST4Contest.app` in den Ordner **Programme**.
+4. Starte KST4Contest aus dem Programme-Ordner oder über das Launchpad.
+
+Die Anwendung ist derzeit nicht von Apple notarisiert. macOS kann den ersten Start deshalb blockieren.
+
+Falls die Anwendung aus dem offiziellen GitHub Release stammt:
+
+1. Öffne den Programme-Ordner im Finder.
+2. Klicke mit der rechten Maustaste oder mit gedrückter Ctrl-Taste auf `KST4Contest.app`.
+3. Wähle **Öffnen**.
+4. Bestätige den Start im angezeigten Dialog.
+
+Alternativ kann macOS unter **Systemeinstellungen → Datenschutz & Sicherheit** die Schaltfläche **Trotzdem öffnen** anbieten.
+
+---
+
+## Wo werden die Einstellungen gespeichert?
+
+KST4Contest speichert seine Einstellungen und weitere lokale Arbeitsdateien im Benutzerverzeichnis. Der Programmordner und das Datenverzeichnis sind voneinander getrennt.
+
+| Betriebssystem | Datenverzeichnis | Einstellungsdatei |
 |---|---|---|
-| `stable` | Aktuelle stabile Version | Jedem normalen Release-Tag |
-| `beta` | Vorab-Version | Tags mit `beta-` Präfix |
-| `nightly` | Entwicklungsstand (main-Branch) | Täglich / jedem Push auf main |
+| Windows | `%USERPROFILE%\.praktiKST\` | `%USERPROFILE%\.praktiKST\preferences.xml` |
+| Linux | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
+| macOS | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |

-Remote einmalig hinzufügen, dann den gewünschten Kanal installieren:
+Beachte die Schreibweise `.praktiKST` mit großem `KST`. Unter Linux und macOS wird zwischen Groß- und Kleinschreibung unterschieden. `.praktikst` wäre dort schlicht ein anderes Verzeichnis.
+
+Ein Programmupdate entfernt dieses Verzeichnis nicht. Trotzdem ist es sinnvoll, vor größeren Versionswechseln oder umfangreichen Änderungen an der Konfiguration eine Sicherung davon anzulegen.
+
+---
+
+## Updates
+
+KST4Contest prüft beim Start, ob ein neueres Stable-Release verfügbar ist. Wenn eine neuere Version gefunden wird, erscheint ein Informationsfenster mit:
+
+- der installierten Version,
+- der aktuellen Stable-Version,
+- einer kurzen Übersicht wesentlicher Änderungen,
+- dem Changelog,
+- bekannten Problemen,
+- einem Link zur passenden GitHub-Release-Seite.
+
+![Update-Hinweis von KST4Contest](update_window.png)
+
+Der Update-Checker installiert nichts selbst. Er informiert über die neue Version und öffnet die plattformneutrale Release-Seite. Dort muss das passende Paket für Windows, Linux oder macOS ausgewählt werden.
+
+### Windows aktualisieren
+
+1. Beende KST4Contest.
+2. Lade das neue Windows-ZIP herunter.
+3. Entpacke es in einen neuen oder leeren Ordner.
+4. Starte die neue Version.
+5. Prüfe, ob die bisherigen Einstellungen geladen wurden.
+6. Entferne den alten Programmordner erst danach.
+
+Die Einstellungen bleiben erhalten, weil sie unter `%USERPROFILE%\.praktiKST` und nicht im Programmordner gespeichert werden.
+
+### AppImage aktualisieren
+
+1. Lade das neue AppImage herunter.
+2. Mache es ausführbar.
+3. Starte die neue Datei.
+4. Entferne das bisherige AppImage erst, wenn die neue Version funktioniert.
+
+### Debian und Ubuntu aktualisieren

 ```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-
-# Stable (Standard)
-flatpak install kst4contest de.x08.KST4Contest
-
-# Beta
-flatpak install kst4contest de.x08.KST4Contest//beta
-
-# Nightly
-flatpak install kst4contest de.x08.KST4Contest//nightly
+sudo apt install ./KST4Contest-v<Version>-debian-amd64.deb
 ```

-> **Hinweis:** Flatpak erlaubt nur eine installierte Version pro App-ID gleichzeitig. Um den Kanal zu wechseln, zuerst die aktuelle Version deinstallieren:
-> ```bash
-> flatpak uninstall de.x08.KST4Contest
-> flatpak install kst4contest de.x08.KST4Contest//nightly
-> ```
+### Fedora aktualisieren

-Updates erfolgen wie gewohnt mit `flatpak update`.
+```bash
+sudo dnf upgrade ./KST4Contest-v<Version>-fedora-x86_64.rpm
+```

-Die `flatpakref`-Dateien für Beta und Stable liegen jeweils im entsprechenden [GitHub-Release](https://github.com/praktimarc/kst4contest/releases). Das Nightly-`flatpakref` (`de.x08.KST4Contest.nightly.flatpakref`) ist als Artifact im [GitHub Actions](https://github.com/praktimarc/kst4contest/actions)-Tab verfügbar (wird 14 Tage aufbewahrt) – der Remote-Weg oben ist für Nightly daher meist einfacher.
+### Arch-Paket aktualisieren

-### macOS
-1. DMG-Datei für die eigene Architektur herunterladen (Apple Silicon oder Intel).
-2. DMG-Datei öffnen.
-3. `KST4Contest.app` in den **Programme**-Ordner ziehen.
-4. Beim ersten Start zeigt macOS ggf. eine Warnung, da die App nicht notarisiert ist. Zum Öffnen:
-   - Rechtsklick (oder Ctrl-Klick) auf `KST4Contest.app` im Finder → **Öffnen** wählen.
-   - Alternativ: **Systemeinstellungen → Datenschutz & Sicherheit** → **Trotzdem öffnen** klicken.
-5. KST4Contest aus dem Programme-Ordner oder dem Launchpad starten.
+```bash
+sudo pacman -U KST4Contest-v<Version>-archlinux-x86_64.pkg.tar.zst
+```

-Die Einstellungen werden unter `~/.praktikst/preferences.xml` gespeichert.
+### AUR-Paket aktualisieren
+
+Aktualisiere das installierte Paket über den verwendeten AUR-Helper, beispielsweise:
+
+```bash
+yay -Syu
+```
+
+### Flatpak aktualisieren
+
+```bash
+flatpak update de.x08.KST4Contest
+```
+
+### macOS aktualisieren
+
+1. Lade die neue DMG-Datei für die vorhandene Architektur herunter.
+2. Beende KST4Contest.
+3. Öffne die DMG-Datei.
+4. Ersetze `KST4Contest.app` im Programme-Ordner.
+5. Starte die neue Version und prüfe die vorhandenen Einstellungen.
+
+Die Konfiguration unter `~/.praktiKST` bleibt davon unberührt.

-## Update
+## Probleme beim ersten Start

-KST4Contest enthält einen **automatischen Update-Hinweis-Dienst**: Sobald eine neue Version verfügbar ist, erscheint beim Start ein Fenster mit:
- der Information, dass eine neue Version vorliegt,
- einem Changelog,
- dem Download-Link zur neuen Version.
+### Windows meldet eine unbekannte Anwendung

-![Beispiel Update Fenster](update_window.png)
+KST4Contest ist derzeit nicht mit einem kommerziellen Windows-Code-Signing-Zertifikat signiert. Windows oder ein zusätzlich installiertes Sicherheitsprodukt kann deshalb vor einer unbekannten oder selten heruntergeladenen Anwendung warnen.

-### Update-Prozess
+Prüfe in diesem Fall zuerst:

-#### Windows
+- Stammt die Datei aus dem [offiziellen KST4Contest-Release](https://github.com/praktimarc/kst4contest/releases/latest)?
+- Passt der Dateiname zum veröffentlichten Release?
+- Wurde die Datei vollständig heruntergeladen?
+- Nennt das Sicherheitsprogramm einen konkreten Erkennungsnamen oder nur eine allgemeine Reputationswarnung?

-Derzeit gibt es nur einen Weg zum Aktualisieren:
+Ein Warnhinweis ist allein weder ein sicherer Beweis für Schadsoftware noch automatisch ein Fehlalarm. Wenn die Herkunft der Datei unklar ist, sollte sie nicht gestartet oder aus der Quarantäne wiederhergestellt werden.

-1. Den alten Ordner löschen.
-2. Das neue ZIP entpacken.
+Einige Anwender haben insbesondere Quarantäne-Meldungen von Norton 360 gemeldet. Wenn sich eine Meldung reproduzieren lässt, erstelle bitte einen [GitHub-Issue](https://github.com/praktimarc/kst4contest/issues) und nenne:

-Die Einstellungsdatei (`preferences.xml`) bleibt erhalten, da sie im Benutzerordner gespeichert ist – nicht im Programmordner.
+- die KST4Contest-Version,
+- den vollständigen Dateinamen,
+- das verwendete Sicherheitsprodukt und dessen Version,
+- den angezeigten Erkennungsnamen,
+- möglichst einen Screenshot der Meldung.

-#### Linux
+### Das AppImage startet nicht

- **AppImage**: Neues AppImage herunterladen, ausführbar machen (`chmod +x`), altes optional löschen.
- **Debian/Ubuntu**: `sudo apt install ./KST4Contest-v<Version>-debian-amd64.deb`
- **Fedora/RHEL**: `sudo dnf upgrade ./KST4Contest-v<Version>-fedora-x86_64.rpm`
- **Arch Linux**: `sudo pacman -U KST4Contest-v<Version>-archlinux-x86_64.pkg.tar.zst`
- **Flatpak (Repository)**: `flatpak update` – aktualisiert alle Flatpak-Apps einschließlich KST4Contest.
+Prüfe zuerst das Ausführungsrecht:

-#### macOS
+```bash
+chmod +x KST4Contest-v<Version>-linux-x86_64.AppImage
+```

-1. Neue DMG-Datei herunterladen.
-2. DMG öffnen.
-3. Die neue `KST4Contest.app` in den **Programme**-Ordner ziehen und die alte Version ersetzen.
+Starte die Datei anschließend aus einem Terminal. Fehlermeldungen sind dort meist aussagekräftiger als ein Doppelklick, der lediglich nichts Sichtbares tut.

+### macOS blockiert die Anwendung

---
+Verwende die unter [Installation unter macOS](#installation-unter-macos) beschriebene Funktion **Öffnen** im Kontextmenü. Prüfe vorher, ob die DMG-Datei aus dem offiziellen GitHub Release stammt.

-## Bekannte Probleme beim Start
+### Das Problem bleibt bestehen

-### Norton 360
+Prüfe zunächst, ob das Problem bereits unter [GitHub Issues](https://github.com/praktimarc/kst4contest/issues) beschrieben wurde. Falls nicht, erstelle einen neuen Issue mit:

-Norton 360 stuft `praktiKST.exe` als gefährlich ein (Fehlalarm). Es muss eine Ausnahme für die Datei eingerichtet werden:
+- Betriebssystem und Version,
+- verwendeter KST4Contest-Version,
+- Installationsart,
+- genauer Fehlermeldung,
+- den Schritten, mit denen sich das Problem reproduzieren lässt.

-1. Norton 360 öffnen.
-2. Sicherheit → Verlauf → Das entsprechende Ereignis suchen.
-3. „Wiederherstellen & Ausnahme hinzufügen" wählen.
-
-*(Gemeldet von PE0WGA, Franz van Velzen – danke!)*
+„Geht nicht“ beschreibt den Zustand meistens korrekt, hilft bei der Fehlersuche aber nur begrenzt.

-**KST4Contest** (also known as *PraktiKST*) is a Java-based chat client for the [ON4KST Chat](http://www.on4kst.info/chat/), specifically designed for contest operation on the VHF/UHF/SHF bands (144 MHz and above).
+KST4Contest is a desktop client for the [ON4KST Chat](https://www.on4kst.org/chat/login.php), developed for VHF, UHF and SHF contest operation. It brings chat, candidate selection, sked planning, aircraft scatter data and external station software together in a single operating interface.

-Developed by **DO5AMF (Marc Fröhlich)**, operator at DM5M.
+KST4Contest is developed by **DO5AMF (Marc Fröhlich)**, operator at DM5M and (since May 2025) **DN9APW (Philipp Wagner)**. The source code is publicly available on [GitHub](https://github.com/praktimarc/kst4contest).

-## Quick Navigation
+## Why use a dedicated ON4KST client?
+
+During a contest, the ON4KST Chat provides a considerable amount of information: active stations, locators, frequencies, sked requests and indications of current activity. The actual problem is not seeing this data. It is turning it into the next useful contact in time.
+
+KST4Contest evaluates the available information, puts it into context and presents it as part of a contest-oriented workflow. This includes antenna direction, distance, known bands and frequencies, worked status, chat activity and aircraft scatter timing.
+
+The program does not decide which QSO is actually possible. Priority scores, the AP timeline and visual highlights are decision aids. The final judgement remains with the operator – not least because even a very convincing computer screen cannot complete a radio contact.
+
+---
+
+## How KST4Contest supports contest operation
+
+- **Observe and organise chat activity:** KST4Contest can display two ON4KST chat categories at the same time. Messages, frequency information and known band activity are assigned to the corresponding stations.
+
+- **Reduce the station list:** Direction, distance, worked and NOT-QRV filters help limit the user list to stations that are relevant to the current operating situation.
+
+- **Prioritise candidates:** The score system evaluates active chat members using several known criteria. The currently most relevant candidates are also shown in a separate priority list.
+
+- **Prepare skeds and keep them visible:** Sked reminders, automatic advance messages and the AP timeline help prevent scheduled contacts from disappearing somewhere between chat, logging and ongoing CQ operation.
+
+- **Include aircraft scatter information:** The AirScout interface brings suitable aircraft and expected reflection times into candidate evaluation and sked planning.
+
+- **Connect the logger and station equipment:** KST4Contest synchronises worked stations and frequency information with supported logging software. It also provides interfaces for Win-Test, PSTRotator and a built-in DX Cluster server.
+
+- **Display stations and radio paths:** The station map shows active chat members, locator squares, antenna directions and the path to the selected station. A terrain profile can also be calculated for selected paths.
+
+These functions share information. A detected frequency can indicate an active band, worked status comes from the logger, aircraft scatter data adds timing information and the resulting score affects the priority list. Missing or outdated input data can therefore affect the result as well.
+
+---
+
+## Requirements
+
+A registered ON4KST account is required. Registration and login are available from the [official ON4KST login page](https://www.on4kst.org/chat/login.php).
+
+English is the official language of the ON4KST Chat. This also applies when communicating with stations from your own country. Common amateur radio abbreviations such as `pse`, `agn`, `qrg`, `dir`, `rrr`, `tnx` and `73` are normal and usually considerably faster than carefully written prose.
+
+Downloads, supported operating systems and installation methods are described in [Installation](en-Installation).
+
+---
+
+## Manual version
+
+This manual describes the stable release **v1.41.1**.
+
+Features or changes that are only available in the current development version are explicitly marked as **Nightly / v1.42**. If no such label is present, the description refers to the stable release.
+
+- [Download the current stable release](https://github.com/praktimarc/kst4contest/releases/latest)
+- [Nightly and automated builds](https://github.com/praktimarc/kst4contest/actions)
+- [Version history](en-Changelog)
+
+For contest operation, the stable release is generally the appropriate choice. Nightly builds contain newer fixes and features, but may change between builds. They are useful when a particular change needs testing. Trying one for the first time ten minutes before a contest is less useful.

-## Prerequisites
+KST4Contest is distributed as a ready-to-run application package for Windows, Linux and macOS. The official release packages do not require a separate Java installation: the required Java runtime is already included.

-An resolution of 1200px by 720px is recommended
+In practical terms, you need a supported operating system, an internet connection and an ON4KST account. That sounds manageable—and usually it is.

-### ON4KST Account
+## Requirements

-To use the chat, a registered account with the ON4KST chat service is required:
+### ON4KST account

- Register at: http://www.on4kst.info/chat/register.php
+KST4Contest is an independent client for the ON4KST chat, but it does not replace the corresponding user account.

-### Chat Etiquette
+If you do not have an account yet, you can create one on the official ON4KST website:

-The official language in the ON4KST Chat is **English**. Please use English even when communicating with stations from your own country. Common HAM abbreviations (agn, dir, pse, rrr, tnx, 73 …) are widely used and understood.
+- [ON4KST login and registration](https://www.on4kst.org/chat/login.php)

-### Personal Messages
+ON4KST specifies English as the common language for the chat. This also applies when both stations happen to share another language. During contests, the usual amateur radio abbreviations such as `pse`, `agn`, `qrg`, `dir`, `rrr`, `tnx` and `73` are widely used.

-To send a private message to another station, always use the following format:
+Using the chat and sending personal messages are covered in the user interface chapter. For the installation, the only thing that matters at this point is that the account works.

-```
-/CQ CALLSIGN message text
-```
+### Screen size

-Example: `/CQ DL5ASG pse sked 144.205?`
+A usable screen area of approximately **1200 × 720 pixels** or more is recommended.

-During heavy chat traffic (5–6 messages per second in a contest), public messages directed at a specific callsign are easily missed. However, KST4Contest also catches such messages if they are accidentally posted publicly (see [Features – PM Catching](Features#catching-personal-messages)).
+KST4Contest automatically adapts the main window to the available area of the primary screen. The application can therefore also be started on smaller displays. Less space is still less space, however: not all tables, filters and additional information can then be displayed at a useful size at the same time.
+
+### Java
+
+The ready-made packages from the [GitHub Releases](https://github.com/praktimarc/kst4contest/releases/latest) do not require a separate Java installation. The required runtime is distributed with KST4Contest.
+
+A Java development environment is only required if you want to build KST4Contest from source. For the AUR packages `kst4contest` and `kst4contest-git`, Java 21 and Maven are handled as build dependencies by the package manager.
+
+---
+
+## Stable, Beta or Nightly?
+
+KST4Contest is distributed through three development channels:
+
+| Channel | Intended use | Classification |
+|---|---|---|
+| **Stable** | Normal contest operation | Published version intended for regular use |
+| **Beta** | Focused testing before a Stable release | Pre-release version with a largely defined feature set |
+| **Nightly** | Early testing of new features | Current development state from the `main` branch |
+
+The **Stable version** is recommended for normal operation.
+
+Beta and Nightly builds may contain features that are not yet available in the Stable release. They may also contain unfinished workflows, changed settings or new defects. That is not an unusual failure of the release process; it is the purpose of a development channel.
+
+If a function in this manual is explicitly marked as **Nightly**, it is not necessarily part of the current Stable release yet.

 ## Download

-### Windows
+The current Stable version is available here:

-The latest version can be downloaded as a ZIP file:
+- [Latest KST4Contest release](https://github.com/praktimarc/kst4contest/releases/latest)
+- [All published releases](https://github.com/praktimarc/kst4contest/releases)

-**https://github.com/praktimarc/kst4contest/releases/latest**
+The release page contains the application packages as well as the English and German PDF manuals.

-The filename has the format `praktiKST-v<version_number>-windows-x64.zip`.
+### Which package do I need?

-### Linux
-
-Multiple package formats are available from the releases page:
-
-**https://github.com/praktimarc/kst4contest/releases/latest**
-
-| Format | Filename | Suitable for |
+| Operating system | Package | Typical filename |
 |---|---|---|
-| AppImage | `KST4Contest-v<version>-linux-x86_64.AppImage` | All distributions |
-| Debian package | `KST4Contest-v<version>-debian-amd64.deb` | Debian, Ubuntu, Linux Mint, … |
-| RPM package | `KST4Contest-v<version>-fedora-x86_64.rpm` | Fedora, RHEL, openSUSE, … |
-| Arch package | `KST4Contest-v<version>-archlinux-x86_64.pkg.tar.zst` | Arch Linux, Manjaro, … |
-| Flatpak | `de.x08.KST4Contest.flatpakref` | All distributions with Flatpak |
-
-> **Recommended for Linux:** The Flatpak installation is the easiest way to stay up to date — `flatpak update` handles all future updates automatically. The repository is GPG-signed for security.
-
-### macOS
-
-> ⚠️ **Best-Effort Support:** macOS builds are provided as a convenience but are **not fully tested**. We build and release macOS binaries with every release, but we cannot test every scenario on macOS. If you encounter issues, please report them – we will do our best to address them, but cannot guarantee the same level of support as for Windows and Linux.
-
-The latest version can be downloaded as a DMG disk image (available for both Apple Silicon and Intel Macs):
-
-**https://github.com/praktimarc/kst4contest/releases/latest**
-
-The filename has the format `KST4Contest-v<version_number>-macos-<arch>.dmg`, where `<arch>` is `arm64` (Apple Silicon) or `x86_64` (Intel).
+| Windows x64 | ZIP package | `praktiKST-v<version>-windows-x64.zip` |
+| Linux x86_64 | AppImage | `KST4Contest-v<version>-linux-x86_64.AppImage` |
+| Debian/Ubuntu amd64 | DEB package | `KST4Contest-v<version>-debian-amd64.deb` |

-## Installation
+## Installing on Windows

-### Windows
+KST4Contest is distributed as a ZIP package for Windows. A conventional installer is not required.

-1. Download the ZIP file.
-2. Unzip the ZIP file into a folder of your choice.
-3. Run `praktiKST.exe`.
+1. Download `praktiKST-v<version>-windows-x64.zip` from the latest release.
+2. Extract the ZIP file completely into a dedicated folder.
+3. Open the extracted folder.
+4. Start `praktiKST.exe`.

-Settings are stored at `%USERPROFILE%\.praktikst\preferences.xml`.
+Do not start the application directly from the compressed ZIP file. KST4Contest consists of several files and a bundled runtime. Windows can only use this structure reliably after the archive has been extracted completely.

-### Linux
+The application settings are not stored in the extracted program directory. They are stored in your user profile:

-Settings are always stored at `~/.praktikst/preferences.xml`.
+```text
+%USERPROFILE%\.praktiKST\preferences.xml
+```

-#### AppImage
+This allows a new application version to be extracted into a different directory without losing the existing settings.

-1. Download the AppImage.
-2. Make it executable: `chmod +x KST4Contest-v<version>-linux-x86_64.AppImage`
-3. Run it.
+---

-#### Debian / Ubuntu
+## Installing on Linux
+
+Several Linux package formats are available. The appropriate choice depends less on KST4Contest itself than on your distribution and the way you prefer to manage updates.
+
+| Installation method | Useful when … |
+|---|---|
+| **Flatpak** | updates should be managed centrally and Flatpak is already in use |
+| **AppImage** | KST4Contest should run as a portable file without package installation |
+| **DEB/RPM** | the distribution’s native package manager should be used |
+| **Arch package/AUR** | Arch Linux, Manjaro or EndeavourOS is being used |
+
+### Flatpak
+
+For most Linux users, Flatpak is the simplest way to keep KST4Contest installed and manageable through the system’s update tools. The KST4Contest repository is GPG-signed and contains the Stable, Beta and Nightly channels.
+
+#### Installing Stable from the release file
+
+Download `de.x08.KST4Contest.flatpakref` from the latest release and open it with the software manager provided by your desktop environment.
+
+Alternatively, install it from a terminal:
+
+```bash
+flatpak install ./de.x08.KST4Contest.flatpakref
+```
+
+#### Adding the KST4Contest repository
+
+The repository only needs to be added once:
+
+```bash
+flatpak remote-add --if-not-exists kst4contest \
+https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
+```
+
+You can then install the Stable version:
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//stable
+```
+
+#### Installing Beta
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//beta
+```
+
+#### Installing Nightly
+
+```bash
+flatpak install kst4contest de.x08.KST4Contest//nightly
+```
+
+All three KST4Contest channels use the same application ID. Installing multiple KST4Contest channels in parallel is therefore not supported.
+
+For example, to switch from Stable to Nightly:
+
+```bash
+flatpak uninstall de.x08.KST4Contest//stable
+flatpak install kst4contest de.x08.KST4Contest//nightly
+```
+
+This does not automatically remove the personal settings stored in `~/.praktiKST`.
+
+Installed Flatpak applications can be updated with:
+
+```bash
+flatpak update de.x08.KST4Contest
+```
+
+Depending on the desktop environment, the graphical software manager may also display or automatically install available Flatpak updates. The `flatpak update` command itself performs an update; it does not promise to turn up and run by itself one day.
+
+### AppImage
+
+The AppImage does not require a conventional installation.
+
+1. Download `KST4Contest-v<version>-linux-x86_64.AppImage`.
+2. Open a terminal in the download directory.
+3. Make the file executable:
+
+```bash
+chmod +x KST4Contest-v<version>-linux-x86_64.AppImage
+```
+
+4. Start KST4Contest:
+
+```bash
+./KST4Contest-v<version>-linux-x86_64.AppImage
+```
+
+The AppImage can then be moved to another location, such as `~/Applications`.
+
+### Debian and Ubuntu
+
+Install the DEB package with:

 ```bash
 sudo apt install ./KST4Contest-v<version>-debian-amd64.deb
 ```

-Or double-click the `.deb` file in your file manager.
+Alternatively, open the file with a graphical package manager.

-#### Fedora / RHEL
+### Fedora and compatible RPM systems
+
+Install the RPM package with:

 ```bash
 sudo dnf install ./KST4Contest-v<version>-fedora-x86_64.rpm
 ```

-#### Arch Linux
+### Arch Linux: installing the release package
+
+The Arch package downloaded from the GitHub Release can be installed directly:

 ```bash
 sudo pacman -U KST4Contest-v<version>-archlinux-x86_64.pkg.tar.zst
 ```

-#### Flatpak
+### Arch Linux: installing from the AUR

-Download `de.x08.KST4Contest.flatpakref` from the [latest release](https://github.com/praktimarc/kst4contest/releases/latest) and open it, or run:
-```bash
-flatpak install de.x08.KST4Contest.flatpakref
-```
+Three variants are available in the AUR:

-Or add the remote manually (recommended for nightly/beta access):
-```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-flatpak install kst4contest de.x08.KST4Contest
-```
+| Package | Content |
+|---|---|
+| [`kst4contest-bin`](https://aur.archlinux.org/packages/kst4contest-bin) | Pre-built package from the current Stable release |
+| [`kst4contest`](https://aur.archlinux.org/packages/kst4contest) | Stable release built locally from source |
+| [`kst4contest-git`](https://aur.archlinux.org/packages/kst4contest-git) | Current development state from the `main` branch |

-#### Flatpak Channels (nightly / beta / stable)
-
-The Flatpak repository provides three channels, all served from the same remote:
-
-| Channel | Content | Built on |
-|---|---|---|
-| `stable` | Current stable version | Every normal release tag |
-| `beta` | Pre-release version | Tags prefixed with `beta-` |
-| `nightly` | Development build (main branch) | Every push to main / daily |
-
-Add the remote once, then install the channel you want:
+For most users, `kst4contest-bin` is the straightforward option:

 ```bash
-flatpak remote-add --if-not-exists kst4contest https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-
-# Stable (default)
-flatpak install kst4contest de.x08.KST4Contest
-
-# Beta
-flatpak install kst4contest de.x08.KST4Contest//beta
-
-# Nightly
-flatpak install kst4contest de.x08.KST4Contest//nightly
+yay -S kst4contest-bin
 ```

-> **Note:** Flatpak only allows one installed version per App-ID at a time. To switch channels, uninstall the current version first:
-> ```bash
-> flatpak uninstall de.x08.KST4Contest
-> flatpak install kst4contest de.x08.KST4Contest//nightly
-> ```
+To build the Stable release from source:

-Updates work as usual with `flatpak update`.
+```bash
+yay -S kst4contest
+```

-The `flatpakref` files for beta and stable are attached to their respective [GitHub Releases](https://github.com/praktimarc/kst4contest/releases). The nightly `flatpakref` (`de.x08.KST4Contest.nightly.flatpakref`) is available as an artifact on the [GitHub Actions](https://github.com/praktimarc/kst4contest/actions) tab (kept for 14 days) — for nightly builds, the manual remote approach above is usually more convenient.
+To build the current development state:

-### macOS
-1. Download the DMG file for your architecture (Apple Silicon or Intel).
+```bash
+yay -S kst4contest-git
+```
+
+All three packages provide the same application and are therefore defined as conflicting with one another. Install only one variant at a time.
+
+AUR updates are included when the selected AUR helper checks for package updates, for example:
+
+```bash
+yay -Syu
+```
+
+They do not happen automatically merely because the package came from the AUR.
+
+---
+
+## Installing on macOS
+
+> **Best-effort support:** The macOS packages are built together with the other releases, but they are not tested to the same extent as the Windows and Linux versions. Feedback is welcome; fully tested support for every macOS version and hardware variant cannot currently be guaranteed.
+
+Apple Silicon Macs require the package marked `arm64`. Intel Macs require the package marked `x86_64`.
+
+1. Download the appropriate DMG file.
 2. Open the DMG file.
-3. Drag `KST4Contest.app` into your **Applications** folder.
-4. On first launch, macOS may show a warning because the app is not notarised. To open it:
-   - Right-click (or Control-click) on `KST4Contest.app` in Finder and choose **Open**.
-   - Alternatively, go to **System Settings → Privacy & Security** and click **Open Anyway**.
-5. Run KST4Contest from your Applications folder or Launchpad.
+3. Drag `KST4Contest.app` into the **Applications** folder.
+4. Start KST4Contest from the Applications folder or Launchpad.

-Settings are stored at `~/.praktikst/preferences.xml`.
+The application is not currently notarized by Apple. macOS may therefore block the first launch.
+
+If the application came from the official GitHub Release:
+
+1. Open the Applications folder in Finder.
+2. Right-click or Control-click `KST4Contest.app`.
+3. Select **Open**.
+4. Confirm the launch in the dialog that appears.
+
+Alternatively, macOS may provide an **Open Anyway** button under **System Settings → Privacy & Security**.

 ---

-## Updating
+## Where are the settings stored?

-KST4Contest includes an **automatic update notification service**: as soon as a new version is available, a window will appear at startup with:
- information that a new version is available,
- a changelog,
- the download link for the new version.
+KST4Contest stores its settings and other local working files in the user’s home directory. The application directory and the data directory are separate.

-![Example Update Window](update_window.png)
+| Operating system | Data directory | Settings file |
+|---|---|---|
+| Windows | `%USERPROFILE%\.praktiKST\` | `%USERPROFILE%\.praktiKST\preferences.xml` |
+| Linux | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
+| macOS | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |

-### Update Process
-
-#### Windows
-
-Currently, there is only one way to update:
-
-1. Delete the old folder.
-2. Unzip the new ZIP file.
-
-The settings file (`preferences.xml`) is preserved because it is stored in the user folder, not the program folder.
-
-#### Linux
-
- **AppImage**: Download the new AppImage, make it executable (`chmod +x`), optionally delete the old one.
- **Debian/Ubuntu**: `sudo apt install ./KST4Contest-v<version>-debian-amd64.deb`
- **Fedora/RHEL**: `sudo dnf upgrade ./KST4Contest-v<version>-fedora-x86_64.rpm`
- **Arch Linux**: `sudo pacman -U KST4Contest-v<version>-archlinux-x86_64.pkg.tar.zst`
- **Flatpak (repository)**: `flatpak update` – updates all Flatpak apps including KST4Contest.
-
-#### macOS
-
-1. Download the new DMG file.
-2. Open the DMG.
-3. Drag the new `KST4Contest.app` into your **Applications** folder, replacing the old version.
+Note the spelling `.praktiKST` with an uppercase `KST`. Linux and macOS distinguish between uppercase and lowercase letters. `.praktikst` would simply be a different directory.

+An application update does not remove this directory. Even so, creating a backup before a major version change or extensive configuration work is sensible.

 ---

-## Known Issues at Startup
+## Updates

-### Norton 360
+When KST4Contest starts, it checks whether a newer Stable release is available. If it finds one, it displays an information window containing:

-Norton 360 classifies `praktiKST.exe` as dangerous (false positive). An exception must be created for the file:
+- the installed version,
+- the latest Stable version,
+- a short overview of the main changes,
+- the changelog,
+- known issues,
+- a link to the corresponding GitHub Release page.

-1. Open Norton 360.
-2. Security → History → Find the corresponding event.
-3. Select "Restore & Add Exception".
+![KST4Contest update notification](update_window.png)

-*(Reported by PE0WGA, Franz van Velzen – thank you!)*
+The update checker does not install anything. It reports the new version and opens the platform-neutral release page. From there, you must select the appropriate package for Windows, Linux or macOS.
+
+### Updating Windows
+
+1. Close KST4Contest.
+2. Download the new Windows ZIP package.
+3. Extract it into a new or empty directory.
+4. Start the new version.
+5. Check that the existing settings have been loaded.
+6. Remove the old application directory only after that.
+
+The settings are preserved because they are stored under `%USERPROFILE%\.praktiKST`, not in the application directory.
+
+### Updating an AppImage
+
+1. Download the new AppImage.
+2. Make it executable.
+3. Start the new file.
+4. Remove the previous AppImage only after the new version works.
+
+### Updating Debian and Ubuntu
+
+```bash
+sudo apt install ./KST4Contest-v<version>-debian-amd64.deb
+```
+
+### Updating Fedora
+
+```bash
+sudo dnf upgrade ./KST4Contest-v<version>-fedora-x86_64.rpm
+```
+
+### Updating the Arch package
+
+```bash
+sudo pacman -U KST4Contest-v<version>-archlinux-x86_64.pkg.tar.zst
+```
+
+### Updating an AUR package
+
+Update the installed package through the selected AUR helper, for example:
+
+```bash
+yay -Syu
+```
+
+### Updating Flatpak
+
+```bash
+flatpak update de.x08.KST4Contest
+```
+
+### Updating macOS
+
+1. Download the new DMG file for the appropriate architecture.
+2. Close KST4Contest.
+3. Open the DMG file.
+4. Replace `KST4Contest.app` in the Applications folder.
+5. Start the new version and check the existing settings.
+
+The configuration under `~/.praktiKST` is not affected.
+
+---
+
+## Problems during the first launch
+
+### Windows reports an unknown application
+
+KST4Contest is not currently signed with a commercial Windows code-signing certificate. Windows or an additional security product may therefore warn about an unknown or rarely downloaded application.
+
+Check the following first:
+
+- Did the file come from the [official KST4Contest release](https://github.com/praktimarc/kst4contest/releases/latest)?
+- Does the filename match the published release?
+- Was the file downloaded completely?
+- Does the security product report a specific detection name or only a general reputation warning?
+
+A warning alone is neither reliable proof of malware nor automatically a false positive. If the origin of the file is unclear, do not run it or restore it from quarantine.
+
+Some users have reported quarantine messages from Norton 360 in particular. If the warning can be reproduced, please create a [GitHub issue](https://github.com/praktimarc/kst4contest/issues) and include:
+
+- the KST4Contest version,
+- the complete filename,
+- the security product and its version,
+- the reported detection name,
+- a screenshot of the warning, if possible.
+
+### The AppImage does not start
+
+Check the executable permission first:
+
+```bash
+chmod +x KST4Contest-v<version>-linux-x86_64.AppImage
+```
+
+Then start the file from a terminal. Error messages shown there are usually more useful than a double-click that simply produces no visible result.
+
+### macOS blocks the application
+
+Use the **Open** function described under [Installing on macOS](#installing-on-macos). Before doing so, verify that the DMG file came from the official GitHub Release.
+
+### The problem remains
+
+First check whether the problem has already been reported under [GitHub Issues](https://github.com/praktimarc/kst4contest/issues). If it has not, create a new issue containing:
+
+- the operating system and version,
+- the KST4Contest version,
+- the installation method,
+- the exact error message,
+- the steps required to reproduce the problem.
+
+“It does not work” usually describes the situation accurately, but it is of limited value during diagnosis.

+# KST4Contest Website Architecture
+
+## Goals
+
+KST4Contest uses GitHub as the central source for code, documentation and releases.
+
+The website is generated statically with Eleventy (11ty) and deployed to:
+
+https://kst4contest.hamradioonline.de
+
+## Documentation Source
+
+The existing `github_docs/` directory remains the single source of truth for the manual.
+
+It is used for:
+
+- GitHub Wiki
+- PDF manual generation
+- Website manual pages
+
+## Website Source
+
+The `website/` directory contains the Eleventy project.
+
+Manual content must not be duplicated inside `website/`.
+
+Marketing, SEO, news, screenshots and download pages belong into `website/src/`.
+
+## URL Structure
+
+- `/`
+- `/features/`
+- `/download/`
+- `/screenshots/`
+- `/news/`
+- `/manual/`
+- `/manual/en/`
+- `/manual/de/`
+- `/faq/`
+
+## Deployment
+
+The generated static output is deployed to:
+
+`/srv/www/kst4contest/current`
+
+Nginx serves this directory.
+
+## Build Strategy
+
+GitHub Actions will later build the 11ty website and deploy the generated output to the server.

+    <h2>Why KST4Contest exists</h2>
+    <p>
+      Generic chat clients display messages. KST4Contest goes further:
+      it helps operators identify candidates, manage skeds, use AirScout timing,
+      synchronize with loggers and reduce workload during VHF/UHF/SHF contests.
+    </p>
+
+    <h2>Open source and practical</h2>
+    <p>
+      The project is open source and focused on practical contest station workflows.
+      Features are designed around real operating pressure, not theoretical UI concepts.
+    </p>
+
+    <h2>Community supported</h2>
+
+    <p>
+
+    KST4Contest is developed independently.
+
+    Community support helps finance hosting,
+    online services,
+    testing across multiple operating systems
+    and future contest-oriented features.

+    <p>
+      Windows users normally need the x64 ZIP package. On Linux, Flatpak is the practical choice when
+      updates should be managed through the desktop software centre or the Flatpak command line. The
+      AppImage is useful when a portable file is preferred, while DEB, RPM and Arch packages integrate
+      with their respective package managers.

+    <p>
+      macOS packages are provided for Apple Silicon and Intel systems on a best-effort basis. They are
+      not currently notarized by Apple. The installation guide covers the first launch, updates, the
+      Stable, Beta and Nightly channels, and the location of the settings directory.

+      KST4Contest is open-source software. The current stable release is the
+      normal choice for contest operation. Nightly builds follow ongoing
+      development and are useful when a particular fix or feature needs
+      testing. A few minutes before a contest is not the ideal time to discover

+        <changed>Migration to Github
+- Band and Frequency Detection per Chatmember — KST4Contest identifies which bands or frequencies a station appears active or reachable on based on chat data. This information is integrated into the display and prioritization.
+- Band Alert — If a logged station could be of interest on other locally active bands, KST14Contest can alert the user.
+- Sked Reminder ALERT — New reminder function for planned Skeds to ensure that agreed contacts are not forgotten during contest operation.
+- Skedfail Button — Failed Skeds can be marked; this allows the station to be handled differently in terms of score and workflow.
+- Win-Test SKED Push via UDP — Skeds can be passed to Win-Test via a LOCKSKED/ADDSKED/UNLOCKSKED sequence. This feature is configurable in the preferences and disabled by default.
+- Win-Test Broadcast Defaults and SKed Workflow — Improved broadcast addresses, frequency formats, mode selection, and notes including locator/azimuth.
+- PSTRotator Interface — KST4Contest received an interface to PSTRoter to better integrate antenna direction and rotator workflow.
+- QSO /-Callsign Sniffer — Callsigns or QSO-relevant information can be detected and utilized for further workflow.
+- Chat History at Startup — Historical chat data can be loaded upon startup, allowing the client to quickly gain relevant context for scoring, activity, and station identification.
+- Station Map / Map View — New map view with station markers, your own location, locator/Maidenhead reference, connection line, and antenna/beam representation.
+- Local Leaflet /-TileProxy Backend — The map function utilizes embedded Leaflet resources and a local TileProxy approach, making the map more portable and independent.
+- Maidenhead /-Grid Overlay — The map can display locator/grid information; recently added Grid-Square coloring.
+- Path /-Terrain /-Horizon Profile — Map documentation describes a path profile with terrain, Fresnel, and horizon information for the selected link.
+- Tropo /-AS Reachability Filters — New filters and sorting were added for Tropospheric reachability, AirScoop availability, large locator fields, and priority.
+- Reachability Band Selector — Added a band selection for range/Troposphere calculations.
+- 4-Char Locator Filter — Locator evaluations can be reduced to 4-character fields; this improves overview and performance.
+- KST Testserver Support — A KST server test server was added into the Source.

+<blockquote>
+<p>🇬🇧 <a href="/manual/en/airscout-integration/">English version</a> | 🇩🇪 Du liest gerade die deutsche Version</p>
+</blockquote>
+<p>AirScout (von DL2ALF) ist ein Programm zur Erkennung von Flugzeugen für den Aircraft-Scatter-Betrieb. KST4Contest ist eng mit AirScout integriert und zeigt reflektierbare Flugzeuge direkt in der Benutzerliste an.</p>
+<blockquote>
+<p><strong>Aircraft Scatter</strong> ermöglicht sehr weitreichende Verbindungen auf VHF und höher – auch für Stationen mit geringer Höhe über NN oder ungünstigen topografischen Verhältnissen.</p>

+<p><strong>Verbesserung in v1.263</strong>: KST4Contest sendet nur noch Stationen an AirScout, deren QRB (Entfernung) kleiner als das eingestellte <strong>Maximum-QRB</strong> ist. Das Abfrageintervall wurde von 12 Sekunden auf <strong>60 Sekunden</strong> verlängert.</p>

+<ul>
+<li>Deutlich weniger Berechnungsaufwand für AirScout</li>
+<li>Deutlich weniger Nachrichtenverkehr</li>
+<li>Das Tracking-Problem mit dem „Show Path in AirScout&quot;-Button wurde dadurch deutlich verbessert</li>
+<li>Weniger Rechenleistung insgesamt</li>
+</ul>
+<p>Außerdem: Der Name des KST4Contest-Clients und des AirScout-Servers war früher hartcodiert (<code>KST</code> und <code>AS</code>). Ab v1.263 werden die in den Preferences eingetragenen Namen verwendet.</p>

+<blockquote>
+<p><strong>Achtung</strong>: Wenn mehrere KST4Contest-Instanzen gleichzeitig betrieben werden und bei beiden die AirScout-Kommunikation aktiviert ist, antwortet AirScout <strong>an beide Instanzen</strong>.</p>
+</blockquote>
+<p>Das ist unproblematisch, wenn:</p>
+<ul>
+<li>Beide Instanzen denselben Locator verwenden, <strong>oder</strong></li>
+<li>Beide Instanzen unterschiedliche Login-Rufzeichen haben.</li>
+</ul>
+<p>Andernfalls kann es zu fehlerhaften AP-Daten kommen.</p>

+<p>Nach der Einrichtung erscheint in der Benutzerliste eine <strong>AP-Spalte</strong> mit bis zu zwei reflektierbaren Flugzeugen pro Station.</p>
+<p>Beispiel-Darstellung:</p>
+<table>

+<p>Die AP-Informationen sind auch im <strong>Privatnachrichten-Fenster</strong> verfügbar.</p>

+<p>letzter Changelog bitte aus GitHub entnehmen. Der bisherige Changelog</p>
+<h2 id="v1.41" tabindex="-1"><a class="header-anchor" href="#v1.41">v1.41</a></h2>
+<p><strong>Stationskarte, Performance, Reaktionsfähiges UI</strong></p>
+<p><strong>Neu:</strong></p>
+<ul>
+<li><strong>Stationskarte</strong>: Interaktive OpenStreetMap-Karte zeigt die geografische Position aller aktiven Chatmember. Enthält Stationsmarker, Antennen-Kegel, Verbindungslinie zur ausgewählten Station, Maidenhead-Raster-Overlay und ein Wegprofil-Diagramm mit Geländehöhen-Analyse (Fresnel-Zonen, Horizonterkennung). Geländedaten aus Copernicus GLO-30, Open-Meteo API oder Offline-DEM-Import. Aircraft-Scatter-Weganalyse integriert. Funktioniert in AppImage und Flatpak ohne externe CDN-Verbindung (lokaler Tile-Proxy, eingebettetes Leaflet.js).</li>
+</ul>
+<p><strong>Geändert:</strong></p>
+<ul>
+<li><strong>Nachrichten-Tabellen-Limit auf 30.000 erhöht</strong>: Chat- und Nachrichtentabellen sind auf 30.000 Einträge begrenzt. Ältere Nachrichten werden automatisch verworfen, was die Performance bei mehrtägigem Contest-Betrieb stabil hält.</li>
+<li><strong>Bildschirmgerechte Fenstergröße</strong>: Beim Start wird das Hauptfenster auf den aktuellen Bildschirm angepasst. Wenn KST4Contest zuletzt auf einem größeren Monitor betrieben wurde, wird das Fenster automatisch verkleinert. Das UI-Layout ist kompakter und reaktionsfähiger auf kleineren Bildschirmen.</li>
+</ul>
+<hr>
+<h2 id="v1.40-(2026-02-16)" tabindex="-1"><a class="header-anchor" href="#v1.40-(2026-02-16)">v1.40 (2026-02-16)</a></h2>
+<p><strong>Großes Feature-Release: Score-System, AP-Timeline, Win-Test, PSTRotator</strong></p>
+<p><strong>Neu:</strong></p>
+<ul>
+<li><strong>Chatmember Score-System</strong>: Jeder Chatmember erhält automatisch eine Prioritätsbewertung anhand von Antennenrichtung, Aktivitätszeit, Nachrichtenanzahl, aktiven Bändern, Frequenzen, Sked-Richtung und anderen Faktoren. Die Top-Kandidaten werden in einer eigenen Liste hervorgehoben.</li>
+<li><strong>AP-Timeline</strong>: Für jeden möglichen AP-Ankunftsminuten-Slot werden bis zu 4 hochbewertete Stationen angezeigt, die erreichbar wären. Bevorzugt werden APs mit dem höchsten Potenzial, nicht die schnellste Ankunft. Stationen, auf die die eigene Antenne nicht zeigt, werden transparent dargestellt.</li>
+<li><strong>Win-Test-Unterstützung</strong> (ab v1.31 als Beta, jetzt vollständig konfigurierbar): Log-Synchronisation, Frequenzauswertung und <strong>Sked-Übergabe via UDP</strong> vollständig integriert. In den Preferences aktivier-/deaktivierbar.</li>
+<li><strong>PSTRotator-Interface</strong> (ab v1.31 als Beta, jetzt vollständig konfigurierbar): Aktualisierung der Rotatorposition direkt aus KST4Contest. In den Preferences aktivier-/deaktivierbar.</li>
+<li><strong>QSO-Sniffer</strong>: Nachrichten von konfigurierbaren Rufzeichen-Listen werden automatisch in das PM-Fenster weitergeleitet.</li>
+<li><strong>Band-Alert bei gearbeiteten Stationen</strong>: Wenn eine Station geloggt wird, erscheint ein Hinweis, wenn diese Station ein weiteres Band aktiv hat, auf dem man selbst ebenfalls QRV ist.</li>
+<li><strong>Sked-Erinnerungs-ALERT</strong>: Pro Chatmember kann ein Sked-Alarm mit automatischen Nachrichten in konfigurierbaren Intervallen (2+1 / 5+2+1 / 10+5+2+1 Minuten vor dem Sked) eingerichtet werden, plus akustische und optische Benachrichtigung.</li>
+<li><strong>Chat-Historie beim Start laden</strong>: Beim Verbindungsaufbau wird die Serverhistorie geladen, um aktive Chatmember und letzte Nachrichten sofort sichtbar zu machen.</li>
+<li><strong>Skedfail-Button</strong>: Im FurtherInfo-Panel kann ein Sked-Misserfolg für einen Chatmember markiert werden, was dessen Score senkt.</li>
+</ul>
+<p><strong>Geändert:</strong></p>
+<ul>
+<li>AP-Notizen in DX-Cluster-Spots integriert.</li>
+<li>Scrolling der Chatmember-Tabelle folgt automatisch der aktuellen Nachrichtenauswahl.</li>
+<li>Generic Auto-Antwort und QRG-Auto-Antwort senden max. einmal pro 45 Sekunden pro Rufzeichen (verhindert Spam-Schleifen).</li>
+<li>Speicherbare Einstellungen erweitert: ServerDNS/Port, PSTRotator-Interface, Win-Test-Interface, Callsign-Sniffer, Dark-Mode-Standard.</li>
+<li>Datum in der Chat-Tabelle entfernt (nur Uhrzeit verbleibt – spart Platz).</li>
+</ul>
+<p><strong>Behoben:</strong></p>
+<ul>
+<li>Benutzerliste wird jetzt bei jedem Neu-Login automatisch sortiert.</li>
+<li>Posonpill-Nachrichten beenden jetzt nur genau eine Client-Instanz (nicht alle und nicht wtKST).</li>
+<li>wtKST: Absturz bei KST4Contest-Trennung behoben.</li>
+<li>Mehrere Probleme mit Rufzeichen-Suffixen wie <code>/p</code>, <code>-2</code> etc. behoben.</li>
+<li><code>QTFDefault</code> wurde nicht korrekt gespeichert → behoben.</li>
+<li>AirScout-Watchlist (ASWATCHLIST) wurde nicht korrekt aktualisiert → behoben.</li>
+<li>Dark Mode: QRG-Felder wurden nicht vollständig angezeigt → behoben.</li>
+<li>Versionsnummer-Anzeige korrigiert.</li>

+<p>🇬🇧 <a href="/manual/en/dx-cluster-server/">English version</a> | 🇩🇪 Du liest gerade die deutsche Version</p>
+</blockquote>
+<p>Ab <strong>Version 1.23</strong> enthält KST4Contest einen integrierten DX-Cluster-Server. Dieser sendet Spots direkt an das Logprogramm, wenn eine Richtungs-Warnung ausgelöst wird.</p>
+<p><em>(Idee von OM0AAO, Viliam Petrik – danke!)</em></p>

+<p>Wenn KST4Contest erkennt, dass eine Station aus der eigenen Richtung ein Sked anfragt und gleichzeitig eine QRG bekannt ist, wird <strong>automatisch ein DX-Cluster-Spot generiert</strong> und an den Cluster-Client des Logprogramms gesendet.</p>
+<p>Das Logprogramm zeigt den Spot in der Bandkarte an. Ein Klick auf den Spot stellt Frequenz und Mode des Transceivers direkt ein – ohne manuelles Eintippen.</p>

+<li><strong>Port</strong> des internen Servers eintragen (z. B. 7300 oder 8000 – muss mit dem Logprogramm übereinstimmen).</li>
+<li><strong>Spotter-Rufzeichen</strong> eintragen – <strong>unbedingt ein anderes Rufzeichen als das Contest-Rufzeichen verwenden!</strong>
+<ul>
+<li>Grund: Logprogramme filtern Spots, die vom eigenen Rufzeichen stammen, als „gearbeitet&quot; heraus. Wenn der Spotter dasselbe Rufzeichen hat, werden die Spots nicht angezeigt.</li>
+</ul>
+</li>
+<li><strong>Angenommene MHz</strong> eintragen: Bei Frequenzangaben wie „.205&quot; im Chat muss KST4Contest entscheiden, ob 144.205, 432.205 oder 1296.205 gemeint ist. Bei Einband-Contests einfach die entsprechende Bandmitte eintragen. Vollständige Frequenzangaben wie „144.205&quot; oder „1296.338&quot; im Chat werden immer korrekt erkannt.</li>

+<li><strong>QRG der Station ist bekannt</strong> (aus dem Chat ausgelesen oder manuell eingetragen).</li>

+<ul>
+<li>Rufzeichen der Station</li>
+<li>Frequenz</li>

+<p>Übersicht aller Hauptfunktionen von KST4Contest.</p>
+<hr>
+<h2 id="sked-richtungs-hervorhebung" tabindex="-1"><a class="header-anchor" href="#sked-richtungs-hervorhebung">Sked-Richtungs-Hervorhebung</a></h2>
+<p>Eine der Kernfunktionen: Wenn eine Station ein Sked in die <strong>eigene Richtung</strong> sendet, wird sie in der Benutzerliste <strong>grün und fett</strong> hervorgehoben.</p>
+<h3 id="wie-funktioniert-das%3F" tabindex="-1"><a class="header-anchor" href="#wie-funktioniert-das%3F">Wie funktioniert das?</a></h3>
+<p>Die Berechnung basiert auf folgender Logik:</p>
+<ul>
+<li>Wenn Station A eine Sked-Anfrage an Station B sendet, wird angenommen, dass A ihre Antenne auf B ausrichtet.</li>
+<li>Wenn die daraus resultierende Richtung von A zur eigenen Station innerhalb des halben Öffnungswinkels der eigenen Antenne liegt, wird A hervorgehoben.</li>
+</ul>
+<p><strong>Beispiel</strong> (Öffnungswinkel 69°, Halbwinkel 34,5°):</p>
+<table>
+<thead>
+<tr>
+<th>Situation</th>
+<th>Ergebnis für DO5AMF in JN49</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>Sked von F5FEN → DM5M</td>
+<td>✅ Hervorhebung (F5FEN zeigt Richtung DM5M, das liegt nahe JN49)</td>
+</tr>
+<tr>
+<td>Sked von DM5M → F5FEN</td>
+<td>✅ Hervorhebung (DM5M antwortet in Richtung F5FEN)</td>
+</tr>
+<tr>
+<td>F1DBN ist unbeteiligt</td>
+<td>❌ Keine Hervorhebung</td>
+</tr>
+<tr>
+<td>DO5AMF/P (anderer Standort)</td>
+<td>❌ Keine Hervorhebung für Sked-Antwort</td>
+</tr>
+</tbody>
+</table>
+<p>Die Berechnung berücksichtigt keine topografischen Wegberechnungen – das ist eine bewusste Vereinfachung. Möglicherweise wird das in einer späteren Version ergänzt.</p>

+<p>Ab <strong>v1.23</strong>: Richtungs-Warnungen werden als DX-Cluster-Spots an das Logprogramm weitergeleitet, wenn eine QRG bekannt ist. Details: <a href="/manual/de/dx-cluster-server/">DX-Cluster-Server</a>.</p>
+<hr>
+<h2 id="qrg-erkennung-(qrg-reading)" tabindex="-1"><a class="header-anchor" href="#qrg-erkennung-(qrg-reading)">QRG-Erkennung (QRG Reading)</a></h2>
+<p>KST4Contest verarbeitet jede Chat-Nachricht und extrahiert automatisch <strong>Frequenzangaben</strong>. Diese werden in der Benutzerliste in der <strong>QRG-Spalte</strong> angezeigt.</p>
+<p>Erkannte Formate: <code>144.205</code>, <code>432.088</code>, <code>.205</code> (mit konfigurierter Bandannahme), etc.</p>
+<p><strong>Nutzen</strong>: Ohne nachzufragen kann man direkt auf die QRG einer Station schauen und entscheiden, ob eine Verbindung möglich ist.</p>
+<hr>
+<h2 id="worked-markierung" tabindex="-1"><a class="header-anchor" href="#worked-markierung">Worked-Markierung</a></h2>
+<p>Gearbeitete Stationen werden in der Benutzerliste visuell markiert – pro Band. Grundlage ist die <a href="/manual/de/log-synchronisation/">Log-Synchronisation</a> via UDP oder Simplelogfile.</p>
+<p>Vor jedem Contest die Datenbank zurücksetzen: <a href="Konfiguration#worked-station-database-settings">Konfiguration – Worked Station Database Settings</a>.</p>
+<hr>
+<h2 id="not-qrv-tags-(ab-v1.2)" tabindex="-1"><a class="header-anchor" href="#not-qrv-tags-(ab-v1.2)">NOT-QRV-Tags (ab v1.2)</a></h2>
+<p>Wenn eine Station mitteilt, dass sie auf einem bestimmten Band nicht QRV ist, kann dies manuell markiert werden:</p>
+<ol>
+<li>Station in der Benutzerliste auswählen.</li>
+<li>Rechtsklick → NOT-QRV für das entsprechende Band setzen.</li>
+</ol>
+<p>Diese Tags werden in der internen Datenbank gespeichert und bleiben nach einem Neustart von KST4Contest erhalten. Zurücksetzen über die Einstellungen möglich.</p>
+<p><strong>Nutzen</strong>: Verhindert wiederholte Sked-Anfragen auf Bändern, auf denen die Station nicht QRV ist – schont sowohl die eigenen Nerven als auch die der Gegenstation.</p>
+<hr>
+<h2 id="richtungsfilter-(direction-filter)" tabindex="-1"><a class="header-anchor" href="#richtungsfilter-(direction-filter)">Richtungsfilter (Direction Filter)</a></h2>
+<p>Zeigt in der Benutzerliste nur Stationen an, die sich in einer bestimmten Richtung befinden. Aktivierbar über die Buttons N / NE / E / SE / S / SW / W / NW oder durch manuelle Eingabe von Grad.</p>
+<p>Sinnvoll: Während man CQ in eine bestimmte Richtung ruft, nur Stationen in dieser Richtung anzeigen.</p>
+<hr>
+<h2 id="entfernungsfilter-(distance-filter)" tabindex="-1"><a class="header-anchor" href="#entfernungsfilter-(distance-filter)">Entfernungsfilter (Distance Filter)</a></h2>
+<p>Stationen jenseits einer maximalen Entfernung ausblenden. Schaltfläche <strong>„Show only QRB [km] &lt;=&quot;</strong> ist ein Toggle-Button.</p>
+<hr>
+<h2 id="worked--und-not-qrv-filter" tabindex="-1"><a class="header-anchor" href="#worked--und-not-qrv-filter">Worked- und NOT-QRV-Filter</a></h2>
+<p>Toggle-Buttons (einer pro Band) zum Ausblenden bereits gearbeiteter Stationen und/oder NOT-QRV-markierter Stationen. Der Filter wirkt <strong>sofort</strong> ohne manuelles Neu-Aktivieren (ab v1.22 live).</p>
+<hr>
+<h2 id="farbige-pm-zeilen-(ab-v1.25)" tabindex="-1"><a class="header-anchor" href="#farbige-pm-zeilen-(ab-v1.25)">Farbige PM-Zeilen (ab v1.25)</a></h2>
+<p>Neue Privatnachrichten erscheinen in <strong>Rot</strong>. Die Farbe wechselt alle 30 Sekunden über Gelb bis Weiß – wie ein Regenbogen-Fade. So ist auf einen Blick erkennbar, wie aktuell eine Nachricht ist.</p>
+<p><em>(Idee von IU3OAR, Gianluca Costantino – danke!)</em></p>
+<hr>
+<h2 id="pm-abfang-(catching-personal-messages)" tabindex="-1"><a class="header-anchor" href="#pm-abfang-(catching-personal-messages)">PM-Abfang (Catching Personal Messages)</a></h2>
+<p>Manche Nutzer senden Direktnachrichten versehentlich öffentlich, z. B.:</p>
+<pre><code>(DM5M) pse ur qrg
+</code></pre>
+<p>KST4Contest erkennt solche Nachrichten, die das eigene Rufzeichen enthalten, und sortiert sie automatisch in die <strong>Privatnachrichten-Tabelle</strong> ein. So gehen keine Nachrichten verloren.</p>
+<hr>
+<h2 id="multi-channel-login-(ab-v1.26)" tabindex="-1"><a class="header-anchor" href="#multi-channel-login-(ab-v1.26)">Multi-Channel-Login (ab v1.26)</a></h2>
+<p>Gleichzeitiger Login in <strong>zwei Chat-Kategorien</strong> (z. B. 144 MHz und 432 MHz). Beide Chats werden parallel überwacht.</p>
+<hr>
+<h2 id="dark-mode-(ab-v1.26)" tabindex="-1"><a class="header-anchor" href="#dark-mode-(ab-v1.26)">Dark Mode (ab v1.26)</a></h2>
+<p>Aktivierbar über: <strong>Window → Use Dark Mode</strong></p>
+<p>Für individuelle Farbanpassungen: CSS-Datei bearbeiten (Pfad in den Programmunterlagen).</p>
+<hr>
+<h2 id="opposite-station-multi-callsign-login-tagging-(ab-v1.26)" tabindex="-1"><a class="header-anchor" href="#opposite-station-multi-callsign-login-tagging-(ab-v1.26)">Opposite Station Multi-Callsign Login-Tagging (ab v1.26)</a></h2>
+<p>Unterstützung für Stationen, die mit mehreren Rufzeichen gleichzeitig im Chat aktiv sind (z. B. Expedition-Setups).</p>
+<hr>
+<h2 id="qrz.com-und-qrz-cq-profil-buttons-(ab-v1.24)" tabindex="-1"><a class="header-anchor" href="#qrz.com-und-qrz-cq-profil-buttons-(ab-v1.24)"><a href="http://QRZ.com">QRZ.com</a> und QRZ-CQ Profil-Buttons (ab v1.24)</a></h2>
+<p>Für ausgewählte Stationen in der Benutzerliste gibt es direkte Buttons, um das <strong>QRZ.com-Profil</strong> und das <strong>QRZ-CQ-Profil</strong> im Browser zu öffnen.</p>
+<hr>
+<h2 id="sked-erinnerungen-mit-alert-(ab-v1.40)" tabindex="-1"><a class="header-anchor" href="#sked-erinnerungen-mit-alert-(ab-v1.40)">Sked-Erinnerungen mit ALERT (ab v1.40)</a></h2>
+<p>Für jeden Chatmember kann ein Sked-Erinnerungsdienst mit automatischen Nachrichten aktiviert werden. Konfigurierbare Intervallmuster:</p>
+<ul>
+<li><strong>2+1 Minuten</strong>: Nachrichten bei 2 min und 1 min vor dem Sked.</li>
+<li><strong>5+2+1 Minuten</strong>: Nachrichten bei 5, 2 und 1 min vor dem Sked.</li>
+<li><strong>10+5+2+1 Minuten</strong>: Nachrichten bei 10, 5, 2 und 1 min vor dem Sked.</li>
+</ul>
+<p>Zusätzlich zu den Nachrichten an die Gegenstation gibt es eine <strong>akustische und optische Benachrichtigung</strong> für den eigenen Operator, sodass kein Sked vergessen wird.</p>
+<p>Aktivierung: FurtherInfo-Panel der entsprechenden Station.</p>
+<hr>
+<h2 id="qso-sniffer-(ab-v1.31)" tabindex="-1"><a class="header-anchor" href="#qso-sniffer-(ab-v1.31)">QSO-Sniffer (ab v1.31)</a></h2>
+<p>Der QSO-Sniffer überwacht den Chat auf Nachrichten von einer konfigurierbaren Rufzeichen-Liste und leitet diese automatisch in das <strong>PM-Fenster</strong> weiter. So gehen keine relevanten Nachrichten im allgemeinen Chat-Rauschen unter.</p>
+<p>Konfiguration: <a href="de-Konfiguration#sniffer-einstellungen-ab-v131">Konfiguration – Sniffer-Einstellungen</a></p>

+<p>KST4Contest unterstützt <a href="https://www.win-test.com/">Win-Test</a> vollständig als Logprogramm:</p>
+<ul>
+<li><strong>Log-Synchronisation</strong>: Gearbeitete Stationen werden automatisch aus Win-Test übernommen und in der Benutzerliste markiert.</li>
+<li><strong>Frequenz-Auswertung</strong>: Die aktuelle TRX-Frequenz wird aus Win-Test-UDP-Paketen ausgewertet und befüllt die <code>MYQRG</code>-Variable.</li>
+<li><strong>Sked-Übergabe (SKED Push via UDP)</strong>: Vereinbarte Skeds aus KST4Contest können direkt an Win-Test übertragen werden, sodass das Rufzeichen der Gegenstation im Win-Test-Sked-Fenster erscheint.</li>
+</ul>
+<p>Details zur Konfiguration: <a href="de-Konfiguration#win-test-netzwerk-listener">Konfiguration – Win-Test-Netzwerk-Listener</a></p>

+<p>KST4Contest kann die Antennenrichtung direkt über <strong>PSTRotator</strong> steuern. Wenn in der Benutzerliste eine Station ausgewählt wird, kann der Rotator automatisch auf den QTF zur ausgewählten Station gedreht werden.</p>
+<p>Konfiguration: <a href="de-Konfiguration#pstrotator-einstellungen-ab-v131">Konfiguration – PSTRotator-Einstellungen</a></p>
+<hr>
+<h2 id="band-alert-bei-neuen-qsos-(ab-v1.40)" tabindex="-1"><a class="header-anchor" href="#band-alert-bei-neuen-qsos-(ab-v1.40)">Band-Alert bei neuen QSOs (ab v1.40)</a></h2>
+<p>Wenn eine Station geloggt wird, prüft KST4Contest automatisch, ob diese Station im Chat weitere aktive Bänder angezeigt hat, auf denen man selbst ebenfalls QRV ist. Falls ja, erscheint ein <strong>Hinweis-Alert</strong>, damit keine Multi-Band-Möglichkeit übersehen wird.</p>
+<hr>
+<h2 id="worked-tag-lebensdauer-(ab-v1.40)" tabindex="-1"><a class="header-anchor" href="#worked-tag-lebensdauer-(ab-v1.40)">Worked-Tag-Lebensdauer (ab v1.40)</a></h2>
+<p>Gearbeitete Stationen werden nach <strong>3 Tagen</strong> automatisch aus der Datenbank entfernt. Ein manuelles Zurücksetzen der Worked-Datenbank vor jedem Contest ist damit nicht mehr zwingend notwendig – die Datenbank hält sich selbst aktuell.</p>
+<hr>
+<h2 id="chatmember-score-system-%2F-priorit%C3%A4tsliste-(ab-v1.40)" tabindex="-1"><a class="header-anchor" href="#chatmember-score-system-%2F-priorit%C3%A4tsliste-(ab-v1.40)">Chatmember Score-System / Prioritätsliste (ab v1.40)</a></h2>
+<p>KST4Contest berechnet automatisch eine <strong>Prioritätsbewertung</strong> für jeden aktiven Chatmember. Der Score setzt sich zusammen aus:</p>
+<ul>
+<li>Antennenrichtung der Gegenstation (zeigt sie auf mich?)</li>
+<li>QRB (Entfernung)</li>
+<li>Aktivitätszeit und Nachrichtenanzahl</li>
+<li>Aktive Bänder und Frequenzen</li>
+<li>AP-Verfügbarkeit (AirScout)</li>
+<li>Sked-Richtung</li>
+<li>Sked-Erfolgsrate und Skedfail-Markierungen</li>
+</ul>
+<p>Die Top-Kandidaten werden in einer eigenen Prioritätsliste hervorgehoben und helfen, im Contest-Stress die wichtigsten Stationen nicht zu übersehen.</p>
+<p>Stationen, bei denen ein Sked gescheitert ist, können über den <strong>Skedfail-Button</strong> im FurtherInfo-Panel markiert werden – das senkt ihren Score vorübergehend.</p>
+<hr>
+<h2 id="ap-timeline-(ab-v1.40)" tabindex="-1"><a class="header-anchor" href="#ap-timeline-(ab-v1.40)">AP-Timeline (ab v1.40)</a></h2>
+<p>Eine visuelle Zeitleiste zeigt für jeden möglichen AP-Ankunftsminuten-Slot bis zu 4 hochbewertete Stationen, die per Aircraft Scatter erreichbar wären. Priorisierungskriterien:</p>
+<ul>
+<li>Bevorzugt werden APs mit dem <strong>höchsten Reflexionspotenzial</strong> (nicht unbedingt die schnellste Ankunft).</li>
+<li>Stationen, auf die die eigene Antenne nicht zeigt, werden <strong>transparent</strong> dargestellt.</li>
+</ul>
+<p>So kann der Contest-Operator auf einem Blick sehen, welche Stationen wann und über welche Flugzeuge erreichbar sein werden.</p>
+<hr>
+<h2 id="intervall-beacon" tabindex="-1"><a class="header-anchor" href="#intervall-beacon">Intervall-Beacon</a></h2>
+<p>Automatische CQ-Meldungen im öffentlichen Kanal in konfigurierbarem Intervall. Empfohlene Verwendung mit der Variable <code>MYQRG</code> für aktuelle Frequenzangabe. Details: <a href="Konfiguration#beacon-settings-automatischer-beacon">Konfiguration – Beacon Settings</a>.</p>
+<hr>
+<h2 id="simplelogfile" tabindex="-1"><a class="header-anchor" href="#simplelogfile">Simplelogfile</a></h2>
+<p>Dateibasierte Log-Auswertung per Regex. Details: <a href="Log-Synchronisation#methode-1-universal-file-based-callsign-interpreter-simplelogfile">Log-Synchronisation</a>.</p>
+<hr>
+<h2 id="cluster-%26-qso-der-anderen" tabindex="-1"><a class="header-anchor" href="#cluster-%26-qso-der-anderen">Cluster &amp; QSO der anderen</a></h2>
+<p>Ein separates Fenster zeigt den QSO-Fluss zwischen anderen Stationen. Besonders interessant in ruhigeren Nacht-Stunden während des Contests, wenn weniger Verkehr herrscht.</p>
+<p>Dieses Fenster kann miniaturisiert werden, wenn es nicht benötigt wird. Zukünftig geplant: Filterung auf Stationen im ausgewählten QTF.</p>
+<hr>
+<h2 id="stationskarte-(ab-v1.41)" tabindex="-1"><a class="header-anchor" href="#stationskarte-(ab-v1.41)">Stationskarte (ab v1.41)</a></h2>
+<p>Eine interaktive OpenStreetMap-Karte zeigt die geografische Position aller aktiven Chatmember.</p>
+<p><strong>Funktionen:</strong></p>
+<ul>
+<li>Stationsmarker mit Rufzeichen-Labels, farblich nach Aktivität und Sked-Status</li>
+<li><strong>Antennen-Kegel</strong> für die eigene Station</li>
+<li><strong>Verbindungslinie</strong> zur aktuell ausgewählten Station</li>
+<li><strong>Maidenhead-Raster</strong> (QRA-Locator-Gitter als Overlay)</li>
+<li><strong>Wegprofil-Diagramm</strong>: Geländehöhen-Querschnitt zwischen eigener und ausgewählter Station, inklusive Fresnel-Zonen-Analyse und Horizonterkennung</li>
+<li>Mehrere Terrainquellen: <strong>Copernicus GLO-30</strong> (hochauflösendes DEM), <strong>Open-Meteo API</strong>, synthetischer Fallback und <strong>Offline-DEM-Import</strong> für den Betrieb ohne Internetverbindung</li>
+<li>Aircraft-Scatter-Weganalyse verknüpft mit den Geländedaten</li>
+</ul>
+<p>Die Karte funktioniert in gepackten Umgebungen (AppImage, Flatpak) ohne Zugriff auf externe CDNs: Die Kartenkacheln werden über einen lokalen Tile-Proxy abgerufen, die Leaflet.js-Bibliothek ist in der Anwendung eingebettet.</p>
+<hr>
+<h2 id="optimierte-nachrichtenverarbeitung-%2F-30.000-nachrichten-limit-(ab-v1.41)" tabindex="-1"><a class="header-anchor" href="#optimierte-nachrichtenverarbeitung-%2F-30.000-nachrichten-limit-(ab-v1.41)">Optimierte Nachrichtenverarbeitung / 30.000-Nachrichten-Limit (ab v1.41)</a></h2>
+<p>Die internen Chat- und Nachrichtentabellen sind auf <strong>30.000 Einträge</strong> begrenzt. Ältere Nachrichten werden automatisch verworfen, sobald das Limit erreicht wird. Damit bleiben Speicherverbrauch und Darstellungsperformance auch bei mehrtägigen Contest-Betrieb stabil.</p>
+<hr>
+<h2 id="bildschirmgerechte-fenstergr%C3%B6%C3%9Fe-(ab-v1.41)" tabindex="-1"><a class="header-anchor" href="#bildschirmgerechte-fenstergr%C3%B6%C3%9Fe-(ab-v1.41)">Bildschirmgerechte Fenstergröße (ab v1.41)</a></h2>
+<p>Beim Programmstart berechnet KST4Contest eine bildschirmgerechte Startgröße für das Hauptfenster:</p>
+<ul>
+<li>Die gespeicherte Fenstergröße aus der letzten Session wird verwendet – aber <strong>niemals größer als der aktuelle Bildschirm</strong>.</li>
+<li>Wenn KST4Contest zuletzt auf einem größeren Monitor betrieben wurde, wird das Fenster automatisch auf die aktuelle Anzeige verkleinert.</li>
+<li>Das UI-Layout ist <strong>kompakter und reaktionsfähiger auf kleineren Bildschirmen</strong>.</li>
+</ul>
+<p>Damit werden unbrauchbare, abgeschnittene Fenster beim Wechsel zwischen Geräten oder Monitoren verhindert.</p>

+<blockquote>
+<p><a href="/manual/en/home/">English version</a> | Du liest gerade die deutsche Version</p>
+</blockquote>
+<p>KST4Contest ist ein Desktop-Client für den <a href="https://www.on4kst.org/chat/login.php">ON4KST-Chat</a>, der für den Contest-Betrieb auf den VHF-, UHF- und SHF-Bändern entwickelt wurde. Er verbindet Chat, Stationsauswahl, Sked-Planung, Aircraft-Scatter-Daten und die Anbindung an weitere Programme in einer gemeinsamen Arbeitsoberfläche.</p>
+<p>Entwickelt wird KST4Contest von <strong>DO5AMF (Marc Fröhlich)</strong>, Operator bei DM5M und (seit Mai 2025) <strong>DN9APW (Philipp Wagner)</strong>. Der Quellcode ist öffentlich auf <a href="https://github.com/praktimarc/kst4contest">GitHub</a> verfügbar.</p>

+<p>Der ON4KST-Chat liefert während eines Contests eine große Menge an Informationen: aktive Stationen, Locator, Frequenzen, Sked-Anfragen und Hinweise auf aktuelle Aktivität. Das eigentliche Problem besteht nicht darin, diese Daten zu sehen. Man muss daraus rechtzeitig die nächste sinnvolle Verbindung ableiten.</p>
+<p>KST4Contest wertet die verfügbaren Informationen aus, ordnet sie und stellt sie in einem contestgerechten Arbeitsablauf dar. Dabei werden unter anderem Antennenrichtung, Entfernung, bekannte Bänder und Frequenzen, bereits gearbeitete Stationen, Chat-Aktivität und Aircraft-Scatter-Zeiten berücksichtigt.</p>
+<p>Das Programm entscheidet jedoch nicht, welches QSO tatsächlich möglich ist. Der Prioritätsscore, die AP-Timeline und die verschiedenen Hervorhebungen sind Entscheidungshilfen. Die endgültige Beurteilung bleibt beim Operator – schon deshalb, weil auch ein recht überzeugender Computerbildschirm noch keine Funkverbindung herstellt.</p>

+<ul>
+<li>
+<p><strong>Chat beobachten und einordnen:</strong> KST4Contest kann zwei ON4KST-Chat-Kategorien gleichzeitig darstellen. Nachrichten, Frequenzangaben und bekannte Bandaktivitäten werden den jeweiligen Stationen zugeordnet.</p>
+</li>
+<li>
+<p><strong>Relevante Stationen herausfiltern:</strong> Richtungs-, Entfernungs-, Worked- und NOT-QRV-Filter reduzieren die Benutzerliste auf die Stationen, die für den aktuellen Betriebszustand tatsächlich interessant sind.</p>
+</li>
+<li>
+<p><strong>Kandidaten priorisieren:</strong> Das Score-System bewertet aktive Chatmember anhand mehrerer bekannter Kriterien. Die derzeit relevantesten Kandidaten erscheinen zusätzlich in einer eigenen Prioritätsliste.</p>
+</li>
+<li>
+<p><strong>Skeds vorbereiten und im Blick behalten:</strong> Sked-Erinnerungen, automatische Vorwarnungen und die AP-Timeline helfen dabei, vereinbarte Verbindungen nicht zwischen Chat, Log und laufendem CQ-Betrieb zu verlieren.</p>
+</li>
+<li>
+<p><strong>Aircraft Scatter einbeziehen:</strong> Über die AirScout-Schnittstelle werden geeignete Flugzeuge und erwartete Reflexionszeiten in die Stationsbewertung und Zeitplanung übernommen.</p>
+</li>
+<li>
+<p><strong>Log und Funkstation anbinden:</strong> KST4Contest synchronisiert gearbeitete Stationen und Frequenzinformationen mit unterstützten Logprogrammen. Zusätzlich stehen Schnittstellen zu Win-Test, PSTRotator und ein integrierter DX-Cluster-Server zur Verfügung.</p>
+</li>
+<li>
+<p><strong>Stationen und Funkwege darstellen:</strong> Die Stationskarte zeigt aktive Chatmember, Locator-Felder, Antennenrichtungen und den Weg zur ausgewählten Station. Für ausgewählte Verbindungen kann außerdem ein Geländeprofil berechnet werden.</p>
+</li>
+</ul>
+<p>Die Funktionen greifen ineinander. Eine erkannte Frequenz kann beispielsweise einem aktiven Band zugeordnet werden, der Worked-Status stammt aus dem Log, Aircraft-Scatter-Daten ergänzen die zeitliche Bewertung und der daraus berechnete Score beeinflusst die Prioritätsliste. Fehlende oder veraltete Eingangsdaten können deshalb auch das Ergebnis beeinflussen.</p>
+<hr>
+<h2 id="voraussetzungen" tabindex="-1"><a class="header-anchor" href="#voraussetzungen">Voraussetzungen</a></h2>
+<p>Für die Anmeldung ist ein registrierter ON4KST-Account erforderlich. Registrierung und Login sind über die <a href="https://www.on4kst.org/chat/login.php">offizielle ON4KST-Anmeldeseite</a> erreichbar.</p>
+<p>Die offizielle Sprache im ON4KST-Chat ist Englisch. Das gilt auch für Nachrichten an Stationen aus dem eigenen Land. Übliche Amateurfunk-Abkürzungen wie <code>pse</code>, <code>agn</code>, <code>qrg</code>, <code>dir</code>, <code>rrr</code>, <code>tnx</code> oder <code>73</code> sind dabei normal und meistens erheblich schneller als ausformulierte Prosa.</p>
+<p>Download, unterstützte Betriebssysteme und Installationswege sind im Kapitel <a href="/manual/de/installation/">Installation</a> beschrieben.</p>

+<h2 id="versionsstand-dieses-handbuchs" tabindex="-1"><a class="header-anchor" href="#versionsstand-dieses-handbuchs">Versionsstand dieses Handbuchs</a></h2>
+<p>Dieses Handbuch beschreibt die stabile Version <strong>v1.41.1</strong>.</p>
+<p>Funktionen oder Änderungen, die nur im aktuellen Entwicklungsstand enthalten sind, werden ausdrücklich als <strong>Nightly / v1.42</strong> gekennzeichnet. Fehlt eine solche Kennzeichnung, bezieht sich die Beschreibung auf die stabile Version.</p>
+<ul>

+<li><a href="https://github.com/praktimarc/kst4contest/actions">Nightly-Builds und automatisierte Builds</a></li>
+<li><a href="/manual/de/changelog/">Versionsgeschichte</a></li>
+</ul>
+<p>Für einen Contest ist grundsätzlich die stabile Version zu empfehlen. Nightly-Builds enthalten neuere Korrekturen und Funktionen, können sich aber zwischen zwei Builds verändern. Sie sind sinnvoll, wenn eine bestimmte Änderung getestet werden soll – weniger sinnvoll ist der erste Versuch zehn Minuten vor Contestbeginn.</p>

+<p>KST4Contest wird für Windows, Linux und macOS als fertiges Programmpaket bereitgestellt. Für die offiziellen Release-Pakete muss Java nicht separat installiert werden: Die benötigte Java-Laufzeitumgebung ist bereits enthalten.</p>
+<p>Benötigt werden damit im Wesentlichen ein unterstütztes Betriebssystem, eine Internetverbindung und ein ON4KST-Account. Das klingt zunächst überschaubar – und ist es normalerweise auch.</p>
+<h2 id="voraussetzungen" tabindex="-1"><a class="header-anchor" href="#voraussetzungen">Voraussetzungen</a></h2>
+<h3 id="on4kst-account" tabindex="-1"><a class="header-anchor" href="#on4kst-account">ON4KST-Account</a></h3>
+<p>KST4Contest ist ein eigenständiger Client für den ON4KST-Chat, ersetzt aber nicht den dazugehörigen Benutzeraccount.</p>
+<p>Falls noch kein Account vorhanden ist, kann er über die offizielle ON4KST-Seite angelegt werden:</p>
+<ul>
+<li><a href="https://www.on4kst.org/chat/login.php">ON4KST-Anmeldung und Registrierung</a></li>
+</ul>
+<p>ON4KST gibt Englisch als gemeinsame Sprache im Chat vor. Das gilt auch dann, wenn beide beteiligten Stationen dieselbe Muttersprache sprechen. Im Contestbetrieb werden häufig die üblichen Amateurfunk-Abkürzungen wie <code>pse</code>, <code>agn</code>, <code>qrg</code>, <code>dir</code>, <code>rrr</code>, <code>tnx</code> oder <code>73</code> verwendet.</p>
+<p>Die eigentliche Bedienung des Chats und das Senden persönlicher Nachrichten werden im Kapitel zur Benutzeroberfläche beschrieben. Für die Installation ist zunächst nur wichtig, dass der Account funktioniert.</p>
+<h3 id="bildschirmgr%C3%B6%C3%9Fe" tabindex="-1"><a class="header-anchor" href="#bildschirmgr%C3%B6%C3%9Fe">Bildschirmgröße</a></h3>
+<p>Eine nutzbare Bildschirmfläche von ungefähr <strong>1200 × 720 Pixeln</strong> oder mehr wird empfohlen.</p>
+<p>KST4Contest passt das Hauptfenster automatisch an die verfügbare Fläche des primären Bildschirms an. Das Programm kann deshalb auch auf kleineren Bildschirmen gestartet werden. Weniger Platz bleibt allerdings weniger Platz: In diesem Fall können nicht alle Tabellen, Filter und Zusatzinformationen gleichzeitig in sinnvoller Größe dargestellt werden.</p>
+<h3 id="java" tabindex="-1"><a class="header-anchor" href="#java">Java</a></h3>
+<p>Für die fertigen Pakete aus den <a href="https://github.com/praktimarc/kst4contest/releases/latest">GitHub Releases</a> ist keine separate Java-Installation erforderlich. Die benötigte Laufzeitumgebung wird zusammen mit KST4Contest ausgeliefert.</p>
+<p>Eine Java-Entwicklungsumgebung wird nur benötigt, wenn KST4Contest selbst aus dem Quellcode gebaut werden soll. Bei den AUR-Paketen <code>kst4contest</code> und <code>kst4contest-git</code> werden Java 21 und Maven als Build-Abhängigkeiten durch den Paketmanager berücksichtigt.</p>

+<p>KST4Contest wird in drei Entwicklungsständen bereitgestellt:</p>

+</tr>
+</tbody>
+</table>
+<p>Für den normalen Einsatz wird die <strong>Stable-Version</strong> empfohlen.</p>
+<p>Beta- und Nightly-Versionen können Funktionen enthalten, die im Stable-Release noch nicht verfügbar sind. Sie können aber ebenso unfertige Bedienabläufe, geänderte Einstellungen oder neue Fehler enthalten. Das ist kein ungewöhnlicher Defekt im Veröffentlichungsverfahren, sondern der Zweck eines Entwicklungskanals.</p>
+<p>Wenn in diesem Manual eine Funktion ausdrücklich mit <strong>Nightly</strong> gekennzeichnet ist, gehört sie noch nicht zwingend zum aktuellen Stable-Release.</p>

+<h2 id="installation-unter-windows" tabindex="-1"><a class="header-anchor" href="#installation-unter-windows">Installation unter Windows</a></h2>
+<p>KST4Contest wird unter Windows als ZIP-Paket bereitgestellt. Ein klassischer Installer ist nicht erforderlich.</p>
+<ol>

+<p>Starte das Programm nicht direkt aus der noch komprimierten ZIP-Datei. KST4Contest besteht aus mehreren Dateien und einer mitgelieferten Laufzeitumgebung. Windows kann diese Struktur nur zuverlässig verwenden, wenn das Archiv vorher vollständig entpackt wurde.</p>
+<p>Die Programmeinstellungen befinden sich nicht im entpackten Programmordner, sondern im Benutzerverzeichnis:</p>
+<pre><code class="language-text">%USERPROFILE%\.praktiKST\preferences.xml

+<p>Dadurch können neue Programmversionen in einen anderen Ordner entpackt werden, ohne dass die vorhandenen Einstellungen verloren gehen.</p>

+<p>Flatpak ist für die meisten Linux-Anwender der einfachste Weg, KST4Contest installiert und aktualisierbar zu halten. Das KST4Contest-Repository ist GPG-signiert und enthält die Kanäle Stable, Beta und Nightly.</p>
+<h4 id="stable-%C3%BCber-die-release-datei-installieren" tabindex="-1"><a class="header-anchor" href="#stable-%C3%BCber-die-release-datei-installieren">Stable über die Release-Datei installieren</a></h4>
+<p>Lade <code>de.x08.KST4Contest.flatpakref</code> aus dem aktuellen Release herunter und öffne die Datei mit der Softwareverwaltung der verwendeten Desktop-Umgebung.</p>
+<p>Alternativ kann sie im Terminal installiert werden:</p>
+<pre><code class="language-bash">flatpak install ./de.x08.KST4Contest.flatpakref
+</code></pre>
+<h4 id="kst4contest-repository-hinzuf%C3%BCgen" tabindex="-1"><a class="header-anchor" href="#kst4contest-repository-hinzuf%C3%BCgen">KST4Contest-Repository hinzufügen</a></h4>
+<p>Das Repository muss nur einmal hinzugefügt werden:</p>
+<pre><code class="language-bash">flatpak remote-add --if-not-exists kst4contest \
+https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
+</code></pre>
+<p>Anschließend kann die Stable-Version installiert werden:</p>
+<pre><code class="language-bash">flatpak install kst4contest de.x08.KST4Contest//stable
+</code></pre>
+<h4 id="beta-installieren" tabindex="-1"><a class="header-anchor" href="#beta-installieren">Beta installieren</a></h4>

+<pre><code class="language-bash">flatpak install kst4contest de.x08.KST4Contest//nightly
+</code></pre>
+<p>KST4Contest verwendet für alle drei Kanäle dieselbe App-ID. Eine parallele Installation mehrerer KST4Contest-Kanäle ist deshalb nicht vorgesehen.</p>
+<p>Zum Wechsel von Stable auf Nightly beispielsweise:</p>
+<pre><code class="language-bash">flatpak uninstall de.x08.KST4Contest//stable
+flatpak install kst4contest de.x08.KST4Contest//nightly
+</code></pre>
+<p>Die persönlichen Einstellungen im Verzeichnis <code>~/.praktiKST</code> werden dabei nicht automatisch gelöscht.</p>
+<p>Installierte Flatpak-Anwendungen können mit folgendem Befehl aktualisiert werden:</p>
+<pre><code class="language-bash">flatpak update de.x08.KST4Contest
+</code></pre>
+<p>Je nach Desktop-Umgebung kann die grafische Softwareverwaltung verfügbare Flatpak-Updates ebenfalls anzeigen oder automatisch installieren. Der Befehl <code>flatpak update</code> selbst führt das Update aus; er verspricht nicht, irgendwann von allein vorbeizukommen.</p>
+<h3 id="appimage" tabindex="-1"><a class="header-anchor" href="#appimage">AppImage</a></h3>
+<p>Das AppImage benötigt keine klassische Installation.</p>

+<li>Öffne ein Terminal im Download-Verzeichnis.</li>

+<p>Die drei Pakete stellen dieselbe Anwendung bereit und sind deshalb als gegenseitige Konflikte definiert. Installiere nur eine Variante gleichzeitig.</p>
+<p>AUR-Updates werden berücksichtigt, wenn der verwendete AUR-Helper nach Paketaktualisierungen sucht, beispielsweise mit:</p>

+</blockquote>
+<p>Nach dem ersten Start öffnet sich das <strong>Einstellungsfenster</strong> – dieses ist der zentrale Ausgangspunkt für alle Konfigurationen. Es empfiehlt sich, das Einstellungsfenster während des Betriebs geöffnet zu lassen (z. B. um den Beacon schnell ein- und auszuschalten).</p>
+<blockquote>
+<p><strong>Wichtig</strong>: Nach jeder Änderung unbedingt <strong>„Save Settings&quot;</strong> klicken! Die Einstellungen werden unter Linux in <code>~/.praktikst/preferences.xml</code> und unter Windows in <code>%USERPROFILE%\.praktikst\preferences.xml</code> (bzw. <code>C:\Users\&lt;Benutzername&gt;\.praktikst\preferences.xml</code>) gespeichert. Ab v1.21 werden auch Fenstergrößen und Divider-Positionen beim Speichern gesichert.</p>

+<h3 id="login-und-chat-kategorien" tabindex="-1"><a class="header-anchor" href="#login-und-chat-kategorien">Login und Chat-Kategorien</a></h3>
+<p>Hier werden die Zugangsdaten für den ON4KST-Chat eingetragen (Rufzeichen und Passwort).
+Zudem wird die <strong>primäre Chat-Kategorie</strong> (z. B. IARU Region 1 VHF/Microwave) ausgewählt.</p>
+<p>Mit der Option für einen <strong>zweiten Chat</strong> (Multi-Channel-Login) kann man sich gleichzeitig in eine weitere Kategorie (z. B. UHF/SHF) einloggen. Beide Chats werden dann parallel überwacht. Hier kann optional auch ein abweichender Login-Name für den zweiten Chat vergeben werden (nützlich für Opposite Station Multi-Callsign Logging).</p>
+<h3 id="rufzeichen-und-locator" tabindex="-1"><a class="header-anchor" href="#rufzeichen-und-locator">Rufzeichen und Locator</a></h3>
+<p>Eigenes Rufzeichen und Maidenhead-Locator (6-stellig, z. B. <code>JN49IJ</code>) eintragen. Diese Werte werden für Distanz- und Richtungsberechnungen benötigt.</p>
+<h3 id="aktivierte-b%C3%A4nder" tabindex="-1"><a class="header-anchor" href="#aktivierte-b%C3%A4nder">Aktivierte Bänder</a></h3>
+<p>Über die <strong>„my station uses band&quot;</strong>-Checkboxen werden die aktiven Bänder ausgewählt. Nur für ausgewählte Bänder erscheinen Schaltflächen und Tabellenzeilen in der Benutzeroberfläche. Nach Änderungen muss die Software neu gestartet werden.</p>
+<h3 id="antennen-%C3%B6ffnungswinkel-(antenna-beamwidth)" tabindex="-1"><a class="header-anchor" href="#antennen-%C3%B6ffnungswinkel-(antenna-beamwidth)">Antennen-Öffnungswinkel (Antenna Beamwidth)</a></h3>
+<p>Einen realistischen Wert für den Öffnungswinkel der eigenen Antenne eintragen (in Grad). Dieser Wert wird für die <a href="Funktionen#sked-richtungs-hervorhebung">Sked-Richtungs-Hervorhebung</a> verwendet. Ein Testwert von 50° hat sich bewährt; DM5M nutzt Quads mit 69°.</p>
+<blockquote>
+<p><strong>Keinesfalls</strong> Fantasy-Werte eintragen – die Richtungsberechnungen werden sonst unbrauchbar.</p>
+</blockquote>
+<h3 id="standard-maximum-qrb" tabindex="-1"><a class="header-anchor" href="#standard-maximum-qrb">Standard-Maximum-QRB</a></h3>
+<p>Maximale Entfernung (in km), für die Richtungs-Warnungen ausgelöst werden sollen. Realistischer Wert für DM5M: 900 km. Stationen, die weiter entfernt sind, werden für Highlighting-Zwecke ignoriert.</p>
+<hr>
+<h2 id="server-einstellungen-(ab-v1.31)" tabindex="-1"><a class="header-anchor" href="#server-einstellungen-(ab-v1.31)">Server-Einstellungen (ab v1.31)</a></h2>
+<p>Der Chat-Server-DNS und -Port sind in den Preferences konfigurierbar:</p>
+<ul>
+<li><strong>Server-DNS</strong>: Standard <code>www.on4kst.org</code> (ab v1.31 geändert von <code>www.on4kst.info</code>).</li>
+<li><strong>Port</strong>: Standardport des ON4KST-Servers.</li>
+</ul>
+<p>Eine Änderung ist nur notwendig, wenn der Server umzieht oder ein alternativer Endpunkt genutzt wird.</p>
+<hr>
+<h2 id="log-sync-einstellungen" tabindex="-1"><a class="header-anchor" href="#log-sync-einstellungen">Log-Sync-Einstellungen</a></h2>
+<p>Drei Methoden stehen zur Verfügung, um gearbeitete Stationen automatisch zu markieren. Details: <a href="/manual/de/log-synchronisation/">Log-Synchronisation</a>.</p>
+<h3 id="universal-file-based-callsign-interpreter-(simplelogfile)" tabindex="-1"><a class="header-anchor" href="#universal-file-based-callsign-interpreter-(simplelogfile)">Universal File Based Callsign Interpreter (Simplelogfile)</a></h3>
+<p>Interpretiert beliebige Log-Dateien per Regex nach Rufzeichen-Mustern. Keine Bandinformation möglich. Geeignet als Fallback oder für nicht direkt unterstützte Logprogramme.</p>
+<h3 id="netzwerk-listener-f%C3%BCr-qso-udp-broadcast" tabindex="-1"><a class="header-anchor" href="#netzwerk-listener-f%C3%BCr-qso-udp-broadcast">Netzwerk-Listener für QSO-UDP-Broadcast</a></h3>
+<p><strong>Empfohlene Methode.</strong> KST4Contest hört auf UDP-Pakete, die das Logprogramm beim Speichern eines QSOs an die Broadcast-Adresse sendet. Die Stationen werden mit Bandinformation markiert. UDP-Port: Standard <strong>12060</strong>. (Wird z. B. von UCXLog, N1MM+, QARTest, <a href="http://DXLog.net">DXLog.net</a> genutzt).</p>
+<h3 id="win-test-network-listener-(zus%C3%A4tzlicher-udp-listener)" tabindex="-1"><a class="header-anchor" href="#win-test-network-listener-(zus%C3%A4tzlicher-udp-listener)">Win-Test Network-Listener (Zusätzlicher UDP-Listener)</a></h3>
+<p>Dedizierter Netzwerk-Erkenner für Win-Test. KST4Contest empfängt und verarbeitet Win-Test-spezifische UDP-Pakete (inkl. Sked-Übergabe) auf dem dafür konfigurierten Port.</p>
+<hr>
+<h2 id="trx-sync-einstellungen" tabindex="-1"><a class="header-anchor" href="#trx-sync-einstellungen">TRX-Sync-Einstellungen</a></h2>
+<p>Empfängt die aktuelle Frequenz des Transceivers vom Logprogramm via UDP. Ermöglicht die automatische Befüllung der Variable <code>MYQRG</code>. Nützlich für:</p>
+<ul>
+<li>Schnelles Einfügen der eigenen QRG in Chat-Nachrichten.</li>
+<li>Automatische CQ-Baken mit aktueller Frequenz.</li>
+</ul>
+<blockquote>
+<p><strong>Hinweis für Multi-Setup</strong>: Wenn zwei Logprogramme an zwei Computern betrieben werden, aber nur eine KST4Contest-Instanz, darf nur ein Logprogramm die Frequenzpakete senden. KST4Contest kann nicht zwischen den Quellen unterscheiden.</p>

+<p>Drei Benachrichtigungstypen stehen zur Wahl:</p>
+<ol>
+<li><strong>Einfache Sounds</strong>: TADA-Sound für eingehende Nachrichten, Tick für Sked-Richtungserkennung usw.</li>
+<li><strong>CW-Ansage</strong>: Das Rufzeichen einer Station, die eine Privatnachricht sendet, wird als CW-Signal ausgegeben.</li>
+<li><strong>Phonetische Ansage</strong>: Das Rufzeichen wird phonetisch ausgesprochen.</li>

+<p>Konfiguration eines automatischen Intervall-Beacons im öffentlichen Chat-Kanal. Empfohlen: Variable <code>MYQRG</code> im Text verwenden, damit die aktuelle Frequenz immer aktuell ist. Intervall und Text sind frei konfigurierbar.</p>
+<blockquote>
+<p><strong>Tipp</strong>: Beacon beim CQ-Rufen aktivieren und im Einstellungsfenster schnell deaktivieren, wenn kein CQ gerufen wird.</p>
+</blockquote>
+<hr>
+<h2 id="messagehandling-settings-(ab-v1.25)" tabindex="-1"><a class="header-anchor" href="#messagehandling-settings-(ab-v1.25)">Messagehandling Settings (ab v1.25)</a></h2>

+<li><strong>Frequenz-Auswertung</strong>: Die aktuelle TRX-Frequenz aus Win-Test befüllt die <code>MYQRG</code>-Variable.</li>
+<li><strong>Sked-Übergabe (SKED Push)</strong>: Skeds aus KST4Contest werden via UDP direkt an Win-Test übergeben. Der UDP-Broadcast-Standardport von Win-Test (9871) wird verwendet.</li>
+</ul>
+<p>Einstellungen:</p>
+<ul>
+<li><strong>Aktivieren/Deaktivieren</strong>: Checkbox in den Preferences (ab v1.40).</li>
+<li><strong>Port</strong>: Konfigurierbarer UDP-Port für den Win-Test-Listener.</li>

+<p>KST4Contest liest eine Log-Datei und sucht mittels regulärem Ausdruck nach Rufzeichen-Mustern. Dabei werden auch binäre Logdateien unterstützt – unlesbarer Binärinhalt wird einfach ignoriert.</p>
+<p><strong>Vorteil</strong>: Funktioniert mit nahezu jedem Logprogramm, das eine Datei schreibt.
+<strong>Nachteil</strong>: Keine Bandinformation möglich – es wird nur „gearbeitet&quot; markiert, nicht auf welchem Band.</p>
+<p>Pfad der Log-Datei in den Preferences eintragen. Die Datei wird nur gelesen, nie verändert (read-only).</p>
+<blockquote>
+<p><strong>Tipp</strong>: Die Simplelogfile-Funktion kann auch genutzt werden, um Stationen zu markieren, die definitiv nicht erreichbar sind (z. B. eigene Notizen). Das wird in einer späteren Version durch ein besseres Tagging-System ersetzt.</p>

+<p>Das Logprogramm sendet beim Speichern eines QSOs ein UDP-Paket an die Broadcast-Adresse des Heimnetzwerks. KST4Contest empfängt dieses Paket und markiert die Station inklusive <strong>Bandinformation</strong> in der internen SQLite-Datenbank.</p>
+<blockquote>
+<p><strong>Wichtig</strong>: KST4Contest muss <strong>parallel zum Logprogramm laufen</strong>. QSOs, die während einer Abwesenheit von KST4Contest geloggt werden, werden nicht erfasst – außer bei QARTest (kann das komplette Log senden).</p>

+<p>Win-Test wird mit einem dedizierten UDP-Netzwerk-Listener unterstützt, der das native Win-Test Netzwerkprotokoll versteht.</p>
+<p><strong>Vorteile der Win-Test Integration:</strong></p>
+<ul>
+<li>Automatische QSO-Synchronisation zur Markierung gearbeiteter Stationen.</li>
+<li><strong>Sked-Übergabe (ADDSKED):</strong> Über den Button “Create sked” im Stationsinfo-Panel wird nicht nur in KST4Contest ein Sked angelegt, sondern dieser auch <em>direkt per UDP an das Win-Test Netzwerk als ADDSKED-Paket gesendet</em> – automatisch, sobald der Listener aktiv ist.</li>
+<li>Es kann zwischen den Sked-Modi “AUTO”, “SSB” oder “CW” gewählt werden.</li>
+<li><strong>Automatische QRG-Auflösung für SKEDs:</strong> KST4Contest wählt die Sked-Frequenz intelligent:
+<ol>
+<li>Hat die Gegenstation in einer Chat-Nachricht ihre QRG genannt, wird diese verwendet.</li>
+<li>Sonst wird die eigene aktuelle QRG verwendet (aus Win-Test STATUS oder manueller Eingabe).</li>
+</ol>
+</li>
+</ul>
+<p><strong>Einstellungen im Reiter „Log-Synchronisation&quot;:</strong></p>
+<ul>
+<li><code>Receive Win-Test network based UDP log messages</code> aktivieren.</li>
+<li><code>UDP-Port for Win-Test listener</code> (Standard: 9871).</li>
+<li><code>KST station name in Win-Test network (src of SKED packets)</code>: Legt fest, unter welchem Stationsnamen KST4Contest im WT-Netzwerk auftritt (z.B. “KST”).</li>
+<li><code>Win-Test network broadcast address</code>: Wird i.d.R. automatisch erkannt; erforderlich für das Senden von Sked-Paketen.</li>
+</ul>
+<p><strong>Einstellungen im Reiter „TRX-Synchronisation&quot;:</strong></p>
+<ul>
+<li><code>Win-Test STATUS QRG Sync</code>: Wenn aktiviert, übernimmt KST4Contest die aktuelle Transceiverfrequenz aus dem Win-Test STATUS-Paket als eigene QRG (MYQRG).</li>
+<li><code>Use pass frequency from Win-Test STATUS</code>: Statt der eigenen TRX-QRG wird die im STATUS-Paket enthaltene Pass-Frequenz als MYQRG verwendet (für Multi-Op-Setups, bei denen mit einer Pass-QRG gearbeitet wird).</li>
+<li><code>Win-Test station name filter</code>: Wird hier ein Name eingetragen (z.B. “STN1”), verarbeitet KST4Contest nur Pakete dieser Win-Test-Instanz. Leer lassen, um alle zu akzeptieren.</li>
+</ul>
+<p><strong>Einstellungen in Win-Test:</strong></p>
+<ul>
+<li>Das Netzwerk in Win-Test muss aktiv sein.</li>
+<li>Win-Test muss so konfiguriert sein, dass es seine Broadcasts an den entsprechenden Port (Standard 9871) sendet bzw. empfängt.</li>
+</ul>

+<h2 id="trx-frequenz-synchronisation" tabindex="-1"><a class="header-anchor" href="#trx-frequenz-synchronisation">TRX-Frequenz-Synchronisation</a></h2>
+<p>Neben der QSO-Synchronisation übertragen UCXLog und andere Programme auch die <strong>aktuelle Transceiverfrequenz</strong> via UDP. KST4Contest verarbeitet diese Information und stellt sie als Variable <code>MYQRG</code> bereit.</p>
+<p><img src="/manual/assets/qrg_buttons.png" alt="FrequenzButtons"></p>
+<p><strong>Ergebnis</strong>: Die eigene QRG muss im Chat nie mehr manuell eingegeben werden – ein Klick auf den MYQRG-Button oder die Verwendung der Variable im Beacon genügt.</p>
+<p><strong>Quellen für die eigene QRG (MYQRG):</strong></p>
+<ul>
+<li>UCXLog, N1MM+, <a href="http://DXLog.net">DXLog.net</a>, QARTest via UDP-Port 12060</li>
+<li>Win-Test STATUS-Paket (optional, konfigurierbar im Reiter „TRX-Synchronisation&quot; unter „Win-Test STATUS QRG Sync&quot;)</li>
+<li>Manuelle Eingabe im QRG-Feld</li>
+</ul>
+<blockquote>
+<p><strong>Hinweis für Multi-Setup</strong>: Bei zwei Logprogrammen an zwei Computern sollte nur <strong>eines</strong> die Frequenzpakete senden. KST4Contest kann nicht zwischen den Quellen unterscheiden und verarbeitet alle eingehenden Pakete.</p>

+<blockquote>
+<p>🇬🇧 You are reading the English version | 🇩🇪 <a href="/manual/de/airscout-integration/">Deutsche Version</a></p>
+</blockquote>
+<p>AirScout (by DL2ALF) is a program for detecting aircraft for aircraft scatter operation. KST4Contest is tightly integrated with AirScout and shows reflectable aircraft directly in the user list.</p>
+<blockquote>
+<p><strong>Aircraft Scatter</strong> enables very long-distance communication on VHF and higher – even for stations with low altitude above sea level or unfavourable topographic conditions.</p>

+<p><strong>Improvement in v1.263</strong>: KST4Contest now only sends stations to AirScout whose QRB (distance) is less than the configured <strong>maximum QRB</strong>. The query interval has been extended from 12 seconds to <strong>60 seconds</strong>.</p>
+<p><strong>Benefits:</strong></p>
+<ul>
+<li>Significantly less computation load for AirScout</li>
+<li>Significantly less message traffic</li>
+<li>The tracking issue with the “Show Path in AirScout” button is greatly improved</li>
+<li>Less overall CPU usage</li>
+</ul>
+<p>Additionally: The name of the KST4Contest client and AirScout server was previously hardcoded (<code>KST</code> and <code>AS</code>). From v1.263, the names configured in the Preferences are used.</p>

+<p>This is not a problem if:</p>
+<ul>
+<li>Both instances use the same locator, <strong>or</strong></li>
+<li>Both instances have different login callsigns.</li>

+<p>Version history of KST4Contest / PraktiKST.</p>
+<hr>
+<p>For the latest changelog, please refer to GitHub. The previous changelog is below.</p>
+<h2 id="v1.41" tabindex="-1"><a class="header-anchor" href="#v1.41">v1.41</a></h2>
+<p><strong>Station Map, Performance, Responsive UI</strong></p>
+<p><strong>New:</strong></p>
+<ul>
+<li><strong>Station Map</strong>: Interactive OpenStreetMap-based map showing the geographic position of all active chat members. Includes station markers, antenna beam cone, connection line to the selected station, Maidenhead grid overlay, and a path profile chart with terrain elevation analysis (Fresnel zones, horizon detection). Terrain data from Copernicus GLO-30, Open-Meteo API, or offline DEM import. Aircraft scatter path analysis integrated. Works in AppImage and Flatpak without external CDN access (local tile proxy, bundled Leaflet.js).</li>
+</ul>
+<p><strong>Changed:</strong></p>
+<ul>
+<li><strong>Message table limit raised to 30,000</strong>: Chat and message tables are capped at 30,000 entries. Older messages are automatically discarded, keeping performance stable during multi-day contest operations.</li>
+<li><strong>Screen-aware window sizing</strong>: On startup, the main window is sized to fit the current screen. If KST4Contest was last used on a larger monitor, the window is automatically scaled down. The UI layout is more compact and responsive on smaller screens.</li>
+</ul>
+<hr>
+<h2 id="v1.40-(2026-02-16)" tabindex="-1"><a class="header-anchor" href="#v1.40-(2026-02-16)">v1.40 (2026-02-16)</a></h2>
+<p><strong>Major Feature Release: Score System, AP Timeline, Win-Test, PSTRotator</strong></p>
+<p><strong>New:</strong></p>
+<ul>
+<li><strong>Chatmember Score System</strong>: Every chat member is automatically scored based on antenna direction, activity time, message count, active bands, frequencies, sked direction (degrees), and other factors. Top candidates are highlighted in a dedicated list.</li>
+<li><strong>AP Timeline</strong>: For each minute of possible aircraft arrival, up to 4 highly-scored stations are shown that should be workable. Aircraft with the highest potential are preferred over the fastest arrival. Chat members whose antenna is not pointing towards you are shown transparently.</li>
+<li><strong>Win-Test Support</strong> (Beta since v1.31, now fully configurable): Log synchronisation, frequency parsing and <strong>sked handover via UDP</strong> fully integrated. Can be enabled/disabled in Preferences.</li>
+<li><strong>PSTRotator Interface</strong> (Beta since v1.31, now fully configurable): Rotator position updates directly from KST4Contest. Can be enabled/disabled in Preferences.</li>
+<li><strong>QSO Sniffer</strong>: Messages from configurable callsign lists are automatically forwarded to the PM window.</li>
+<li><strong>Band Alert for logged stations</strong>: When a station is logged, a hint appears if that station has another active band that you are also QRV on.</li>
+<li><strong>Sked Reminder ALERT</strong>: A sked alarm with automatic messages in configurable intervals (2+1 / 5+2+1 / 10+5+2+1 minutes before the sked) can be set up for each chat member, plus acoustic and visual notification.</li>
+<li><strong>Load chat history on startup</strong>: Chat server history is loaded on connect to immediately see active members and recent messages.</li>
+<li><strong>Skedfail button</strong>: In the FurtherInfo panel, a sked failure can be marked for a chat member, which lowers their priority score.</li>
+</ul>
+<p><strong>Changed:</strong></p>
+<ul>
+<li>AP notes added to internal DX cluster spots.</li>
+<li>Chat member table scrolling follows the current message selection automatically.</li>
+<li>Generic auto-reply and QRG auto-reply now fire a maximum of once every 45 seconds per callsign (prevents spam and message ping-pong).</li>
+<li>New saveable settings: ServerDNS/Port, PSTRotator interface, Win-Test interface, callsign sniffer, Dark Mode on by default.</li>
+<li>Date column removed from chat table (time only – saves space).</li>
+</ul>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>User list now automatically sorted on every new member sign-on.</li>
+<li>Posonpill messages now terminate exactly one client instance (no longer affects all instances or wtKST).</li>
+<li>wtKST: crash on KST4Contest disconnection fixed.</li>
+<li>Multiple issues with callsign suffixes like <code>/p</code>, <code>-2</code>, etc. fixed throughout.</li>
+<li><code>QTFDefault</code> was not saved correctly → fixed.</li>
+<li>AirScout watchlist (ASWATCHLIST) was not being updated → fixed.</li>
+<li>Dark Mode: QRG fields not displayed at full size → fixed.</li>
+<li>Version number display corrected.</li>
+</ul>

+<p><strong>Win-Test + PSTRotator Beta, QSO Sniffer, DNS Hotfix</strong></p>
+<p><strong>New:</strong></p>
+<ul>
+<li><strong>Win-Test support</strong> (Beta, not yet deactivatable): Log synchronisation and frequency parsing.</li>
+<li><strong>PSTRotator support</strong> (Beta, not yet deactivatable).</li>
+<li><strong>QSO Sniffer</strong>: Messages from configurable callsigns are forwarded to the PM window.</li>
+</ul>
+<p><strong>Changed:</strong></p>
+<ul>
+<li><strong>DNS server changed</strong>: From <code>www.on4kst.info</code> to <code>www.on4kst.org</code> (hotfix). The DNS server is now configurable in Preferences.</li>
+</ul>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>Endless loop in error case freezes the client → fixed.</li>
+</ul>
+<hr>
+<h2 id="v1.266-(2025-10-03)" tabindex="-1"><a class="header-anchor" href="#v1.266-(2025-10-03)">v1.266 (2025-10-03)</a></h2>
+<p><strong>AirScout Fix for Callsigns with Suffix</strong></p>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>AirScout interface did not work when the login callsign contained a suffix (e.g. <code>9A1W-2</code>). AirScout cannot handle this format – only the base callsign without suffix is now passed to AirScout.</li>
+</ul>
+<p><em>(Bug reported and tested by 9A2HM / Kreso – many thanks!)</em></p>

+<h2 id="v1.265-(2025-09-28)" tabindex="-1"><a class="header-anchor" href="#v1.265-(2025-09-28)">v1.265 (2025-09-28)</a></h2>
+<p><strong>Direction Buttons Stay Coloured When Active</strong></p>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>Direction buttons (N / NE / E etc.) now keep their highlight colour when activated, making the active state immediately visible.</li>
+</ul>
+<hr>
+<h2 id="v1.264-(2025-08-02)" tabindex="-1"><a class="header-anchor" href="#v1.264-(2025-08-02)">v1.264 (2025-08-02)</a></h2>
+<p><strong>Simplelogfile: Improved Callsign Recognition</strong></p>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>Callsigns like <code>S53CC</code>, <code>S51A</code>, etc. were not being marked as worked in the SimpleLogFile interpreter → recognition pattern improved.</li>
+</ul>
+<p><em>(Bug reported by Boris, S53CC – thank you!)</em></p>

+<p><strong>AirScout Communication and Login Name</strong></p>
+<p><strong>Changed:</strong></p>
+<ul>
+<li>AirScout communication fundamentally revised: Only stations with QRB &lt; max-QRB are now sent to AirScout.</li>
+<li>Query interval extended from 12 seconds to <strong>60 seconds</strong>.</li>
+<li>Significantly less computation load and message traffic → more stable AirScout tracking.</li>
+<li>Name of the AS client and AS server is now configurable from the Preferences (was previously hardcoded to “KST” / “AS”).</li>
+</ul>
+<p><strong>Fixed:</strong></p>
+<ul>
+<li>“Track in AirScout” button was very sluggish → greatly improved by new communication logic.</li>
+<li>Name in chat is now saveable (bug fixed).</li>
+<li>Visual corrections before and after login.</li>
+<li>Bug fixed that was reported by 9A2HM (Kreso).</li>

+<blockquote>
+<p>🇬🇧 You are reading the English version | 🇩🇪 <a href="/manual/de/konfiguration/">Deutsche Version</a></p>
+</blockquote>
+<p>After the first start, the <strong>settings window</strong> opens – this is the central starting point for all configuration. It is recommended to keep the settings window open during operation (e.g. to quickly toggle the beacon on and off).</p>
+<blockquote>
+<p><strong>Important</strong>: Always click <strong>“Save Settings”</strong> after any change! Settings are stored in <code>~/.praktikst/preferences.xml</code> on Linux and in <code>%USERPROFILE%\.praktikst\preferences.xml</code> (or <code>C:\Users\&lt;Username&gt;\.praktikst\preferences.xml</code>) on Windows. From v1.21 onwards, window sizes and divider positions are also saved when you click Save.</p>

+<h3 id="login-and-chat-categories" tabindex="-1"><a class="header-anchor" href="#login-and-chat-categories">Login and Chat Categories</a></h3>
+<p>Enter your ON4KST chat credentials here (callsign and password).
+Also, select the <strong>primary chat category</strong> (e.g., IARU Region 1 VHF/Microwave).</p>
+<p>With the option for a <strong>second chat</strong> (Multi-Channel Login), you can log in to another category simultaneously (e.g., UHF/SHF). Both chats will then be monitored in parallel. You can optionally specify a different login name for the second chat (useful for Opposite Station Multi-Callsign Logging).</p>
+<h3 id="callsign-and-locator" tabindex="-1"><a class="header-anchor" href="#callsign-and-locator">Callsign and Locator</a></h3>
+<p>Enter your own callsign and Maidenhead locator (6 characters, e.g., <code>JN49IJ</code>). These values are needed for distance and direction calculations.</p>
+<h3 id="active-bands" tabindex="-1"><a class="header-anchor" href="#active-bands">Active Bands</a></h3>
+<p>Use the <strong>“my station uses band”</strong> checkboxes to select the active bands. Buttons and table rows will only appear in the user interface for selected bands. The software must be restarted after making changes.</p>
+<h3 id="antenna-beamwidth" tabindex="-1"><a class="header-anchor" href="#antenna-beamwidth">Antenna Beamwidth</a></h3>
+<p>Enter a realistic value for your antenna’s beamwidth (in degrees). This value is used for the <a href="Features#sked-direction-highlighting">Sked Direction Highlighting</a>. A test value of 50° has proven effective; DM5M uses quads with 69°.</p>
+<blockquote>
+<p><strong>Do not</strong> enter fantasy values – the direction calculations will become useless.</p>

+<p>Three methods are available for automatically marking worked stations. Details: <a href="/manual/en/log-sync/">Log Synchronisation</a>.</p>
+<h3 id="universal-file-based-callsign-interpreter-(simplelogfile)" tabindex="-1"><a class="header-anchor" href="#universal-file-based-callsign-interpreter-(simplelogfile)">Universal File Based Callsign Interpreter (Simplelogfile)</a></h3>
+<p>Interprets any log file using regex for callsign patterns. No band information is available. Suitable as a fallback or for log programs that are not directly supported.</p>
+<h3 id="network-listener-for-logger%E2%80%99s-qso-udp-broadcast" tabindex="-1"><a class="header-anchor" href="#network-listener-for-logger%E2%80%99s-qso-udp-broadcast">Network Listener for Logger’s QSO UDP Broadcast</a></h3>
+<p><strong>Recommended method.</strong> KST4Contest listens for UDP packets sent by the logging software to the broadcast address when a QSO is saved. Stations are marked with band information. UDP port: default <strong>12060</strong>. (Used by UCXLog, N1MM+, QARTest, <a href="http://DXLog.net">DXLog.net</a>, etc.).</p>
+<h3 id="win-test-network-listener-(additional-udp-listener)" tabindex="-1"><a class="header-anchor" href="#win-test-network-listener-(additional-udp-listener)">Win-Test Network Listener (Additional UDP Listener)</a></h3>
+<p>A dedicated network listener for Win-Test. KST4Contest receives and processes Win-Test-specific UDP packets (including sked handovers) on the configured port.</p>
+<hr>
+<h2 id="trx-sync-settings" tabindex="-1"><a class="header-anchor" href="#trx-sync-settings">TRX Sync Settings</a></h2>
+<p>Receives the current transceiver frequency from the logging software via UDP. This enables the automatic population of the <code>MYQRG</code> variable. Useful for:</p>
+<ul>
+<li>Quickly inserting your own QRG into chat messages.</li>
+<li>Automatic CQ beacon with current frequency.</li>
+</ul>
+<blockquote>
+<p><strong>Note for multi-setup</strong>: When running two logging programs on two computers but only one KST4Contest instance, only one logging program should send frequency packets. KST4Contest cannot distinguish between sources.</p>

+<p>Three notification types are available:</p>
+<ol>
+<li><strong>Simple sounds</strong>: TADA sound for incoming messages, tick for sked direction detection, etc.</li>
+<li><strong>CW announcement</strong>: The callsign of a station sending a private message is output as a CW signal.</li>
+<li><strong>Phonetic announcement</strong>: The callsign is pronounced phonetically.</li>
+</ol>
+<hr>
+<h2 id="shortcut-settings" tabindex="-1"><a class="header-anchor" href="#shortcut-settings">Shortcut Settings</a></h2>
+<p>Configuration of quick-access buttons that appear directly in the main window. Clicking a button inserts the configured text into the send field. All <a href="Macros-and-Variables#variables">variables</a> can be used.</p>

+<li><strong>Right-click</strong> in the CQ message table</li>
+<li><strong>Right-click</strong> in the PM message table</li>
+<li><strong>Keyboard shortcuts</strong>: <code>Ctrl+1</code> to <code>Ctrl+0</code> for the first 10 snippets</li>
+</ul>
+<p>If a callsign is selected in the user list, the snippet is addressed as a direct message:
+<code>/CQ CALLSIGN &lt;snippet text&gt;</code></p>
+<hr>
+<h2 id="beacon-settings" tabindex="-1"><a class="header-anchor" href="#beacon-settings">Beacon Settings</a></h2>
+<p>Configuration of an automatic interval beacon in the public chat channel. Recommended: use the <code>MYQRG</code> variable in the text so the current frequency is always up to date. Interval and text are freely configurable.</p>
+<blockquote>
+<p><strong>Tip</strong>: Enable the beacon when calling CQ and quickly disable it in the settings window when not calling.</p>

+<ul>
+<li><strong>Auto-reply to all incoming messages</strong>: Configurable automatic reply to private messages.</li>
+<li><strong>Auto-reply with own CQ QRG</strong>: When someone asks for your QRG, KST4Contest automatically replies with the content of the <code>MYQRG</code> variable.</li>
+<li><strong>Default filter for the userinfo window</strong>: Pre-configured message filter for the station info window <em>(for Gianluca :-) )</em>.</li>
+</ul>
+<hr>
+<h2 id="win-test-network-listener-(from-v1.31)" tabindex="-1"><a class="header-anchor" href="#win-test-network-listener-(from-v1.31)">Win-Test Network Listener (from v1.31)</a></h2>
+<p>A dedicated listener for Win-Test-specific UDP packets. Enables:</p>
+<ul>
+<li><strong>Log synchronisation</strong>: Worked stations are retrieved from Win-Test and marked in the user list.</li>
+<li><strong>Frequency parsing</strong>: The current TRX frequency from Win-Test populates the <code>MYQRG</code> variable.</li>
+<li><strong>Sked handover (SKED push)</strong>: Skeds from KST4Contest are passed directly to Win-Test via UDP. Win-Test’s default UDP broadcast port (9871) is used.</li>
+</ul>
+<p>Settings:</p>
+<ul>
+<li><strong>Enable/Disable</strong>: Checkbox in Preferences (from v1.40).</li>
+<li><strong>Port</strong>: Configurable UDP port for the Win-Test listener.</li>
+<li><strong>Sked UDP address and port</strong>: Target address and port for SKED handover to Win-Test.</li>
+</ul>
+<blockquote>
+<p><strong>Note</strong>: The Win-Test listener is an <strong>additional</strong> listener – the standard QSO UDP broadcast listener on port 12060 remains independent.</p>

+<p>Settings:</p>
+<ul>
+<li><strong>Callsign list</strong>: Comma-separated list of callsigns whose messages are always forwarded to the PM window.</li>
+</ul>
+<p>Use case: Keep track of important stations (e.g. DX expeditions or trusted contest allies) without constantly monitoring the main chat.</p>
+<hr>
+<h2 id="worked-station-database-settings" tabindex="-1"><a class="header-anchor" href="#worked-station-database-settings">Worked Station Database Settings</a></h2>
+<p>The internal worked database contains:</p>

+<blockquote>
+<p>🇬🇧 You are reading the English version | 🇩🇪 <a href="/manual/de/dx-cluster-server/">Deutsche Version</a></p>
+</blockquote>
+<p>From <strong>version 1.23</strong>, KST4Contest includes a built-in DX cluster server. It sends spots directly to the logging software whenever a direction warning is triggered.</p>
+<p><em>(Idea by OM0AAO, Viliam Petrik – thank you!)</em></p>
+<hr>
+<h2 id="what-is-the-built-in-dx-cluster-server-for%3F" tabindex="-1"><a class="header-anchor" href="#what-is-the-built-in-dx-cluster-server-for%3F">What is the Built-in DX Cluster Server For?</a></h2>
+<p>When KST4Contest detects that a station is requesting a sked from your direction and a QRG is known, it <strong>automatically generates a DX cluster spot</strong> and feeds it directly to the logging software’s cluster client / band map.</p>
+<p>The logging software then displays the spot in the band map. Clicking the spot sets the transceiver’s frequency and mode directly – without any manual typing.</p>
+<hr>
+<h2 id="setup" tabindex="-1"><a class="header-anchor" href="#setup">Setup</a></h2>
+<h3 id="in-kst4contest" tabindex="-1"><a class="header-anchor" href="#in-kst4contest">In KST4Contest</a></h3>
+<p>In Preferences → <strong>DX Cluster Server Settings</strong>:</p>
+<ol>
+<li>Enter the <strong>port</strong> of the internal server (e.g. 7300 or 8000 – must match the logging software).</li>
+<li>Enter a <strong>spotter callsign</strong> – <strong>this must be a different callsign than your contest callsign!</strong>
+<ul>
+<li>Reason: Logging programs filter spots from your own callsign as “already worked”. If the spotter uses the same callsign, the spots will not be displayed.</li>
+</ul>
+</li>
+<li>Enter the <strong>assumed MHz</strong>: For frequency references like “.205” in the chat, KST4Contest needs to decide whether 144.205, 432.205 or 1296.205 is meant. For single-band contests, simply enter the corresponding band centre. Full frequency references like “144.205” or “1296.338” in the chat are always correctly identified.</li>
+</ol>
+<h3 id="in-ucxlog" tabindex="-1"><a class="header-anchor" href="#in-ucxlog">In UCXLog</a></h3>
+<ul>
+<li>Configure a DX cluster server connection:
+<ul>
+<li>Host: <code>127.0.0.1</code> (or IP of the KST4Contest computer)</li>
+<li>Port: As configured in KST4Contest</li>
+<li>Password: can be left empty</li>
+</ul>
+</li>
+<li>Use the <strong>“Send a test message to your log”</strong> button to test the connection.</li>
+</ul>
+<h3 id="in-n1mm%2B" tabindex="-1"><a class="header-anchor" href="#in-n1mm%2B">In N1MM+</a></h3>
+<p>Similar settings:</p>
+<ul>
+<li>Host: <code>127.0.0.1</code> (or IP of the KST4Contest computer)</li>
+<li>Port: As configured in KST4Contest</li>
+</ul>
+<hr>
+<h2 id="how-it-works" tabindex="-1"><a class="header-anchor" href="#how-it-works">How It Works</a></h2>
+<p>A spot is generated when <strong>both</strong> conditions are met:</p>
+<ol>
+<li>A <strong>direction warning</strong> has been triggered (station is making a sked in your direction).</li>
+<li>The <strong>station’s QRG is known</strong> (read from the chat or manually entered).</li>
+</ol>
+<p>The generated spot contains:</p>
+<ul>
+<li>Station’s callsign</li>
+<li>Frequency</li>
+<li>Spot time</li>
+</ul>
+<p>The logging software can then display the spot in the band map and tune the TRX to that frequency with a mouse click.</p>
+<hr>
+<h2 id="multi-computer-setup" tabindex="-1"><a class="header-anchor" href="#multi-computer-setup">Multi-Computer Setup</a></h2>
+<p>If KST4Contest runs on a separate computer (not the logging computer):</p>
+<ul>
+<li>Host in the logging software: IP of the KST4Contest computer (not <code>127.0.0.1</code>)</li>
+<li>Same configuration as for the QSO UDP broadcast packets (see <a href="/manual/en/log-sync/">Log Synchronisation</a>)</li>

+<hr>
+<h2 id="sked-direction-highlighting" tabindex="-1"><a class="header-anchor" href="#sked-direction-highlighting">Sked Direction Highlighting</a></h2>
+<p>One of the core features: when a station makes a sked request <strong>towards your direction</strong>, it is highlighted <strong>green and bold</strong> in the user list.</p>
+<h3 id="how-does-it-work%3F" tabindex="-1"><a class="header-anchor" href="#how-does-it-work%3F">How does it work?</a></h3>
+<p>The calculation is based on the following logic:</p>
+<ul>
+<li>When station A sends a sked request to station B, it is assumed that A is pointing its antenna towards B.</li>
+<li>If the resulting direction from A to your own station is within half the beamwidth of your own antenna, A is highlighted.</li>
+</ul>
+<p><strong>Example</strong> (beamwidth 69°, half-angle 34.5°):</p>
+<table>
+<thead>
+<tr>
+<th>Situation</th>
+<th>Result for DO5AMF in JN49</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td>Sked from F5FEN → DM5M</td>
+<td>✅ Highlighted (F5FEN points towards DM5M, close to JN49)</td>
+</tr>
+<tr>
+<td>Sked from DM5M → F5FEN</td>
+<td>✅ Highlighted (DM5M replies towards F5FEN)</td>
+</tr>
+<tr>
+<td>F1DBN is uninvolved</td>
+<td>❌ No highlighting</td>
+</tr>
+<tr>
+<td>DO5AMF/P (different location)</td>
+<td>❌ No highlighting for sked reply</td>
+</tr>
+</tbody>
+</table>
+<p>The calculation does not include topographic path calculations – this is a deliberate simplification. It may be added in a future version.</p>

+<h2 id="sked-direction-spots-(built-in-dx-cluster)" tabindex="-1"><a class="header-anchor" href="#sked-direction-spots-(built-in-dx-cluster)">Sked Direction Spots (Built-in DX Cluster)</a></h2>
+<p>From <strong>v1.23</strong>: Direction warnings are forwarded as DX cluster spots to the logging software when a QRG is known. Details: <a href="/manual/en/dx-cluster-server/">DX Cluster Server</a>.</p>
+<hr>
+<h2 id="qrg-detection-(qrg-reading)" tabindex="-1"><a class="header-anchor" href="#qrg-detection-(qrg-reading)">QRG Detection (QRG Reading)</a></h2>
+<p>KST4Contest processes every line of text flowing through the channel and automatically extracts <strong>frequency references</strong>. These are displayed in the user list in the <strong>QRG column</strong>.</p>
+<p>Recognised formats: <code>144.205</code>, <code>432.088</code>, <code>.205</code> (with configured band assumption), etc.</p>
+<p><strong>Benefit</strong>: Without asking, you can directly look up a station’s calling frequency and decide whether a contact is possible.</p>
+<hr>
+<h2 id="worked-marking" tabindex="-1"><a class="header-anchor" href="#worked-marking">Worked Marking</a></h2>
+<p>Worked stations are visually marked in the user list – per band. Based on <a href="/manual/en/log-sync/">Log Synchronisation</a> via UDP or Simplelogfile.</p>
+<p>Reset the database before each contest: <a href="Configuration#worked-station-database-settings">Configuration – Worked Station Database Settings</a>.</p>
+<hr>
+<h2 id="not-qrv-tags-(from-v1.2)" tabindex="-1"><a class="header-anchor" href="#not-qrv-tags-(from-v1.2)">NOT-QRV Tags (from v1.2)</a></h2>
+<p>When a station indicates it is not QRV on a specific band, this can be manually marked:</p>
+<ol>
+<li>Select the station in the user list.</li>
+<li>Right-click → Set NOT-QRV for the appropriate band.</li>
+</ol>
+<p>These tags are stored in the internal database and persist after a KST4Contest restart. Can be reset via the settings.</p>
+<p><strong>Benefit</strong>: Prevents repeated sked requests on bands where the station is not active – saves time for both sides.</p>
+<hr>
+<h2 id="direction-filter" tabindex="-1"><a class="header-anchor" href="#direction-filter">Direction Filter</a></h2>
+<p>Shows only stations in the user list that are located in a specific direction. Toggle using the N / NE / E / SE / S / SW / W / NW buttons or by entering degrees manually.</p>
+<p>Useful: While calling CQ in a specific direction, only show stations in that direction.</p>
+<hr>
+<h2 id="distance-filter" tabindex="-1"><a class="header-anchor" href="#distance-filter">Distance Filter</a></h2>
+<p>Hide stations beyond a maximum distance. The <strong>“Show only QRB [km] &lt;=”</strong> button is a toggle.</p>
+<hr>
+<h2 id="worked-and-not-qrv-filter" tabindex="-1"><a class="header-anchor" href="#worked-and-not-qrv-filter">Worked and NOT-QRV Filter</a></h2>
+<p>Toggle buttons (one per band) to hide already-worked stations and/or NOT-QRV-tagged stations. The filter takes effect <strong>immediately</strong> without manually reactivating (live since v1.22).</p>
+<hr>
+<h2 id="coloured-pm-rows-(from-v1.25)" tabindex="-1"><a class="header-anchor" href="#coloured-pm-rows-(from-v1.25)">Coloured PM Rows (from v1.25)</a></h2>
+<p>New private messages appear in <strong>red</strong>. The colour fades every 30 seconds from yellow to white – like a rainbow fade. This makes it immediately clear how recent a message is.</p>

+<p>Some users accidentally post direct messages publicly, e.g.:</p>
+<pre><code>(DM5M) pse ur qrg

+<p>A sked reminder service with automatic messages can be activated for each chat member. Configurable interval patterns:</p>
+<ul>
+<li><strong>2+1 minutes</strong>: Messages at 2 min and 1 min before the sked.</li>
+<li><strong>5+2+1 minutes</strong>: Messages at 5, 2 and 1 min before the sked.</li>
+<li><strong>10+5+2+1 minutes</strong>: Messages at 10, 5, 2 and 1 min before the sked.</li>
+</ul>
+<p>In addition to the automated messages to the remote station, there is an <strong>acoustic and visual notification</strong> for your own operator so no sked is ever missed.</p>
+<p>Activate from the FurtherInfo panel of the corresponding station.</p>

+<p>KST4Contest fully supports <a href="https://www.win-test.com/">Win-Test</a> as a logging programme:</p>
+<ul>
+<li><strong>Log synchronisation</strong>: Worked stations are automatically retrieved from Win-Test and marked in the user list.</li>
+<li><strong>Frequency parsing</strong>: The current TRX frequency is read from Win-Test UDP packets and populates the <code>MYQRG</code> variable.</li>
+<li><strong>Sked handover (SKED push via UDP)</strong>: Agreed skeds from KST4Contest can be pushed directly to Win-Test, so the remote callsign appears in Win-Test’s sked window.</li>

+<p>When a station is logged, KST4Contest automatically checks whether that station has shown any other active bands in the chat that you are also QRV on. If so, a <strong>hint alert</strong> appears so no multi-band opportunity is missed.</p>
+<hr>
+<h2 id="worked-tag-lifetime-(from-v1.40)" tabindex="-1"><a class="header-anchor" href="#worked-tag-lifetime-(from-v1.40)">Worked Tag Lifetime (from v1.40)</a></h2>
+<p>Worked stations are automatically removed from the database after <strong>3 days</strong>. Manually resetting the worked database before each contest is therefore no longer strictly necessary – the database keeps itself up to date.</p>
+<hr>
+<h2 id="chatmember-score-system-%2F-priority-list-(from-v1.40)" tabindex="-1"><a class="header-anchor" href="#chatmember-score-system-%2F-priority-list-(from-v1.40)">Chatmember Score System / Priority List (from v1.40)</a></h2>
+<p>KST4Contest automatically calculates a <strong>priority score</strong> for each active chat member. The score is derived from:</p>
+<ul>
+<li>Antenna direction of the remote station (is it pointing towards me?)</li>
+<li>QRB (distance)</li>
+<li>Activity time and message count</li>
+<li>Active bands and frequencies</li>
+<li>AP availability (AirScout)</li>
+<li>Sked direction (degrees)</li>
+<li>Sked success rate and skedfail markings</li>
+</ul>
+<p>The top candidates are highlighted in a dedicated priority list, helping you not to miss the most important contacts during contest stress.</p>
+<p>Stations with a failed sked can be marked using the <strong>Skedfail button</strong> in the FurtherInfo panel – this temporarily lowers their score.</p>
+<hr>
+<h2 id="ap-timeline-(from-v1.40)" tabindex="-1"><a class="header-anchor" href="#ap-timeline-(from-v1.40)">AP Timeline (from v1.40)</a></h2>
+<p>A visual timeline shows up to 4 highly-scored stations per minute slot that should be workable via aircraft scatter. Prioritisation criteria:</p>
+<ul>
+<li><strong>Highest reflection potential</strong> is preferred (not necessarily the fastest arrival).</li>
+<li>Stations towards which your antenna is not pointing are shown <strong>transparently</strong>.</li>
+</ul>
+<p>This gives the contest operator a quick overview of which stations will be reachable via which aircraft and at what time.</p>
+<hr>
+<h2 id="interval-beacon" tabindex="-1"><a class="header-anchor" href="#interval-beacon">Interval Beacon</a></h2>
+<p>Automatic CQ messages in the public channel at a configurable interval. Recommended: use the <code>MYQRG</code> variable so the current frequency is always accurate. Details: <a href="Configuration#beacon-settings">Configuration – Beacon Settings</a>.</p>
+<hr>
+<h2 id="simplelogfile" tabindex="-1"><a class="header-anchor" href="#simplelogfile">Simplelogfile</a></h2>
+<p>File-based log evaluation using regex. Details: <a href="Log-Sync#method-1-universal-file-based-callsign-interpreter-simplelogfile">Log Synchronisation</a>.</p>
+<hr>
+<h2 id="cluster-%26-qso-of-others" tabindex="-1"><a class="header-anchor" href="#cluster-%26-qso-of-others">Cluster &amp; QSO of Others</a></h2>
+<p>A separate window showing the QSO flow between other stations. Particularly interesting during quieter night-time hours of a contest. This window can be minimised when not needed. Future plan: filtering to stations in your selected QTF.</p>
+<hr>
+<h2 id="station-map-(from-v1.41)" tabindex="-1"><a class="header-anchor" href="#station-map-(from-v1.41)">Station Map (from v1.41)</a></h2>
+<p>An interactive OpenStreetMap-based map showing the geographic position of all active chat members.</p>
+<p><strong>Features:</strong></p>
+<ul>
+<li>Station markers with callsign labels, coloured by activity and sked state</li>
+<li>Antenna <strong>beam cone</strong> visualisation for the own station</li>
+<li><strong>Connection line</strong> to the currently selected station</li>
+<li><strong>Maidenhead grid</strong> overlay (QRA locator grid)</li>
+<li><strong>Path profile chart</strong>: Terrain elevation cross-section between own station and the selected station, including Fresnel zone analysis and obstruction/horizon detection</li>
+<li>Multiple terrain data sources: <strong>Copernicus GLO-30</strong> (high-resolution DEM), <strong>Open-Meteo API</strong>, synthetic fallback, and <strong>offline DEM import</strong> for air-gapped use</li>
+<li>Aircraft scatter path analysis integrated with the terrain data</li>
+</ul>
+<p>The map works in packaged environments (AppImage, Flatpak) without internet access to external CDNs: map tiles are fetched via a local tile proxy, and the Leaflet.js library is bundled inside the application.</p>
+<hr>
+<h2 id="optimised-message-handling-%2F-30%2C000-message-limit-(from-v1.41)" tabindex="-1"><a class="header-anchor" href="#optimised-message-handling-%2F-30%2C000-message-limit-(from-v1.41)">Optimised Message Handling / 30,000 Message Limit (from v1.41)</a></h2>
+<p>The internal chat and message tables are capped at <strong>30,000 entries</strong>. Older messages are automatically discarded when the limit is reached. This keeps memory usage and rendering performance stable during multi-day contest operations.</p>
+<hr>
+<h2 id="screen-aware-window-sizing-(from-v1.41)" tabindex="-1"><a class="header-anchor" href="#screen-aware-window-sizing-(from-v1.41)">Screen-Aware Window Sizing (from v1.41)</a></h2>
+<p>On startup, KST4Contest calculates a screen-aware size for the main window:</p>
+<ul>
+<li>The stored window size from the previous session is used – but <strong>never larger than the current screen</strong>.</li>
+<li>If KST4Contest was last used on a larger monitor, the window is automatically scaled down to fit the current display without clipping.</li>
+<li>The UI layout is more <strong>compact and responsive on smaller screens</strong>, showing the same information in less space.</li>
+</ul>
+<p>This prevents unusable oversized windows when switching between machines or monitors.</p>

+<blockquote>
+<p>You are reading the English version | <a href="/manual/de/home/">Deutsche Version</a></p>
+</blockquote>
+<p>KST4Contest is a desktop client for the <a href="https://www.on4kst.org/chat/login.php">ON4KST Chat</a>, developed for VHF, UHF and SHF contest operation. It brings chat, candidate selection, sked planning, aircraft scatter data and external station software together in a single operating interface.</p>
+<p>KST4Contest is developed by <strong>DO5AMF (Marc Fröhlich)</strong>, operator at DM5M and (since May 2025) <strong>DN9APW (Philipp Wagner)</strong>. The source code is publicly available on <a href="https://github.com/praktimarc/kst4contest">GitHub</a>.</p>

+<h2 id="why-use-a-dedicated-on4kst-client%3F" tabindex="-1"><a class="header-anchor" href="#why-use-a-dedicated-on4kst-client%3F">Why use a dedicated ON4KST client?</a></h2>
+<p>During a contest, the ON4KST Chat provides a considerable amount of information: active stations, locators, frequencies, sked requests and indications of current activity. The actual problem is not seeing this data. It is turning it into the next useful contact in time.</p>
+<p>KST4Contest evaluates the available information, puts it into context and presents it as part of a contest-oriented workflow. This includes antenna direction, distance, known bands and frequencies, worked status, chat activity and aircraft scatter timing.</p>
+<p>The program does not decide which QSO is actually possible. Priority scores, the AP timeline and visual highlights are decision aids. The final judgement remains with the operator – not least because even a very convincing computer screen cannot complete a radio contact.</p>
+<hr>
+<h2 id="how-kst4contest-supports-contest-operation" tabindex="-1"><a class="header-anchor" href="#how-kst4contest-supports-contest-operation">How KST4Contest supports contest operation</a></h2>
+<ul>
+<li>
+<p><strong>Observe and organise chat activity:</strong> KST4Contest can display two ON4KST chat categories at the same time. Messages, frequency information and known band activity are assigned to the corresponding stations.</p>
+</li>
+<li>
+<p><strong>Reduce the station list:</strong> Direction, distance, worked and NOT-QRV filters help limit the user list to stations that are relevant to the current operating situation.</p>
+</li>
+<li>
+<p><strong>Prioritise candidates:</strong> The score system evaluates active chat members using several known criteria. The currently most relevant candidates are also shown in a separate priority list.</p>
+</li>
+<li>
+<p><strong>Prepare skeds and keep them visible:</strong> Sked reminders, automatic advance messages and the AP timeline help prevent scheduled contacts from disappearing somewhere between chat, logging and ongoing CQ operation.</p>
+</li>
+<li>
+<p><strong>Include aircraft scatter information:</strong> The AirScout interface brings suitable aircraft and expected reflection times into candidate evaluation and sked planning.</p>
+</li>
+<li>
+<p><strong>Connect the logger and station equipment:</strong> KST4Contest synchronises worked stations and frequency information with supported logging software. It also provides interfaces for Win-Test, PSTRotator and a built-in DX Cluster server.</p>
+</li>
+<li>
+<p><strong>Display stations and radio paths:</strong> The station map shows active chat members, locator squares, antenna directions and the path to the selected station. A terrain profile can also be calculated for selected paths.</p>
+</li>
+</ul>
+<p>These functions share information. A detected frequency can indicate an active band, worked status comes from the logger, aircraft scatter data adds timing information and the resulting score affects the priority list. Missing or outdated input data can therefore affect the result as well.</p>
+<hr>
+<h2 id="requirements" tabindex="-1"><a class="header-anchor" href="#requirements">Requirements</a></h2>
+<p>A registered ON4KST account is required. Registration and login are available from the <a href="https://www.on4kst.org/chat/login.php">official ON4KST login page</a>.</p>
+<p>English is the official language of the ON4KST Chat. This also applies when communicating with stations from your own country. Common amateur radio abbreviations such as <code>pse</code>, <code>agn</code>, <code>qrg</code>, <code>dir</code>, <code>rrr</code>, <code>tnx</code> and <code>73</code> are normal and usually considerably faster than carefully written prose.</p>
+<p>Downloads, supported operating systems and installation methods are described in <a href="/manual/en/installation/">Installation</a>.</p>
+<hr>
+<h2 id="manual-version" tabindex="-1"><a class="header-anchor" href="#manual-version">Manual version</a></h2>
+<p>This manual describes the stable release <strong>v1.41.1</strong>.</p>
+<p>Features or changes that are only available in the current development version are explicitly marked as <strong>Nightly / v1.42</strong>. If no such label is present, the description refers to the stable release.</p>
+<ul>
+<li><a href="https://github.com/praktimarc/kst4contest/releases/latest">Download the current stable release</a></li>
+<li><a href="https://github.com/praktimarc/kst4contest/actions">Nightly and automated builds</a></li>
+<li><a href="/manual/en/changelog/">Version history</a></li>
+</ul>
+<p>For contest operation, the stable release is generally the appropriate choice. Nightly builds contain newer fixes and features, but may change between builds. They are useful when a particular change needs testing. Trying one for the first time ten minutes before a contest is less useful.</p>

+<blockquote>
+<p>🇬🇧 You are reading the English version | 🇩🇪 <a href="/manual/de/installation/">Deutsche Version</a></p>
+</blockquote>
+<p>KST4Contest is distributed as a ready-to-run application package for Windows, Linux and macOS. The official release packages do not require a separate Java installation: the required Java runtime is already included.</p>
+<p>In practical terms, you need a supported operating system, an internet connection and an ON4KST account. That sounds manageable—and usually it is.</p>
+<h2 id="requirements" tabindex="-1"><a class="header-anchor" href="#requirements">Requirements</a></h2>
+<h3 id="on4kst-account" tabindex="-1"><a class="header-anchor" href="#on4kst-account">ON4KST account</a></h3>
+<p>KST4Contest is an independent client for the ON4KST chat, but it does not replace the corresponding user account.</p>
+<p>If you do not have an account yet, you can create one on the official ON4KST website:</p>
+<ul>
+<li><a href="https://www.on4kst.org/chat/login.php">ON4KST login and registration</a></li>
+</ul>
+<p>ON4KST specifies English as the common language for the chat. This also applies when both stations happen to share another language. During contests, the usual amateur radio abbreviations such as <code>pse</code>, <code>agn</code>, <code>qrg</code>, <code>dir</code>, <code>rrr</code>, <code>tnx</code> and <code>73</code> are widely used.</p>
+<p>Using the chat and sending personal messages are covered in the user interface chapter. For the installation, the only thing that matters at this point is that the account works.</p>
+<h3 id="screen-size" tabindex="-1"><a class="header-anchor" href="#screen-size">Screen size</a></h3>
+<p>A usable screen area of approximately <strong>1200 × 720 pixels</strong> or more is recommended.</p>
+<p>KST4Contest automatically adapts the main window to the available area of the primary screen. The application can therefore also be started on smaller displays. Less space is still less space, however: not all tables, filters and additional information can then be displayed at a useful size at the same time.</p>
+<h3 id="java" tabindex="-1"><a class="header-anchor" href="#java">Java</a></h3>
+<p>The ready-made packages from the <a href="https://github.com/praktimarc/kst4contest/releases/latest">GitHub Releases</a> do not require a separate Java installation. The required runtime is distributed with KST4Contest.</p>
+<p>A Java development environment is only required if you want to build KST4Contest from source. For the AUR packages <code>kst4contest</code> and <code>kst4contest-git</code>, Java 21 and Maven are handled as build dependencies by the package manager.</p>
+<hr>
+<h2 id="stable%2C-beta-or-nightly%3F" tabindex="-1"><a class="header-anchor" href="#stable%2C-beta-or-nightly%3F">Stable, Beta or Nightly?</a></h2>
+<p>KST4Contest is distributed through three development channels:</p>
+<table>
+<thead>
+<tr>
+<th>Channel</th>
+<th>Intended use</th>
+<th>Classification</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td><strong>Stable</strong></td>
+<td>Normal contest operation</td>

+</tr>
+<tr>
+<td><strong>Nightly</strong></td>
+<td>Early testing of new features</td>
+<td>Current development state from the <code>main</code> branch</td>
+</tr>
+</tbody>
+</table>
+<p>The <strong>Stable version</strong> is recommended for normal operation.</p>
+<p>Beta and Nightly builds may contain features that are not yet available in the Stable release. They may also contain unfinished workflows, changed settings or new defects. That is not an unusual failure of the release process; it is the purpose of a development channel.</p>
+<p>If a function in this manual is explicitly marked as <strong>Nightly</strong>, it is not necessarily part of the current Stable release yet.</p>
+<hr>
+<h2 id="download" tabindex="-1"><a class="header-anchor" href="#download">Download</a></h2>
+<p>The current Stable version is available here:</p>

+<li><a href="https://github.com/praktimarc/kst4contest/releases">All published releases</a></li>

+<hr>
+<h2 id="installing-on-windows" tabindex="-1"><a class="header-anchor" href="#installing-on-windows">Installing on Windows</a></h2>
+<p>KST4Contest is distributed as a ZIP package for Windows. A conventional installer is not required.</p>
+<ol>
+<li>Download <code>praktiKST-v&lt;version&gt;-windows-x64.zip</code> from the latest release.</li>
+<li>Extract the ZIP file completely into a dedicated folder.</li>
+<li>Open the extracted folder.</li>
+<li>Start <code>praktiKST.exe</code>.</li>
+</ol>
+<p>Do not start the application directly from the compressed ZIP file. KST4Contest consists of several files and a bundled runtime. Windows can only use this structure reliably after the archive has been extracted completely.</p>
+<p>The application settings are not stored in the extracted program directory. They are stored in your user profile:</p>
+<pre><code class="language-text">%USERPROFILE%\.praktiKST\preferences.xml
+</code></pre>
+<p>This allows a new application version to be extracted into a different directory without losing the existing settings.</p>
+<hr>
+<h2 id="installing-on-linux" tabindex="-1"><a class="header-anchor" href="#installing-on-linux">Installing on Linux</a></h2>
+<p>Several Linux package formats are available. The appropriate choice depends less on KST4Contest itself than on your distribution and the way you prefer to manage updates.</p>
+<table>
+<thead>
+<tr>
+<th>Installation method</th>
+<th>Useful when …</th>
+</tr>
+</thead>
+<tbody>
+<tr>
+<td><strong>Flatpak</strong></td>
+<td>updates should be managed centrally and Flatpak is already in use</td>

+<h3 id="flatpak" tabindex="-1"><a class="header-anchor" href="#flatpak">Flatpak</a></h3>
+<p>For most Linux users, Flatpak is the simplest way to keep KST4Contest installed and manageable through the system’s update tools. The KST4Contest repository is GPG-signed and contains the Stable, Beta and Nightly channels.</p>
+<h4 id="installing-stable-from-the-release-file" tabindex="-1"><a class="header-anchor" href="#installing-stable-from-the-release-file">Installing Stable from the release file</a></h4>
+<p>Download <code>de.x08.KST4Contest.flatpakref</code> from the latest release and open it with the software manager provided by your desktop environment.</p>
+<p>Alternatively, install it from a terminal:</p>
+<pre><code class="language-bash">flatpak install ./de.x08.KST4Contest.flatpakref
+</code></pre>
+<h4 id="adding-the-kst4contest-repository" tabindex="-1"><a class="header-anchor" href="#adding-the-kst4contest-repository">Adding the KST4Contest repository</a></h4>
+<p>The repository only needs to be added once:</p>
+<pre><code class="language-bash">flatpak remote-add --if-not-exists kst4contest \
+https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
+</code></pre>
+<p>You can then install the Stable version:</p>
+<pre><code class="language-bash">flatpak install kst4contest de.x08.KST4Contest//stable
+</code></pre>
+<h4 id="installing-beta" tabindex="-1"><a class="header-anchor" href="#installing-beta">Installing Beta</a></h4>
+<pre><code class="language-bash">flatpak install kst4contest de.x08.KST4Contest//beta
+</code></pre>
+<h4 id="installing-nightly" tabindex="-1"><a class="header-anchor" href="#installing-nightly">Installing Nightly</a></h4>
+<pre><code class="language-bash">flatpak install kst4contest de.x08.KST4Contest//nightly
+</code></pre>
+<p>All three KST4Contest channels use the same application ID. Installing multiple KST4Contest channels in parallel is therefore not supported.</p>
+<p>For example, to switch from Stable to Nightly:</p>
+<pre><code class="language-bash">flatpak uninstall de.x08.KST4Contest//stable
+flatpak install kst4contest de.x08.KST4Contest//nightly
+</code></pre>
+<p>This does not automatically remove the personal settings stored in <code>~/.praktiKST</code>.</p>
+<p>Installed Flatpak applications can be updated with:</p>
+<pre><code class="language-bash">flatpak update de.x08.KST4Contest
+</code></pre>
+<p>Depending on the desktop environment, the graphical software manager may also display or automatically install available Flatpak updates. The <code>flatpak update</code> command itself performs an update; it does not promise to turn up and run by itself one day.</p>
+<h3 id="appimage" tabindex="-1"><a class="header-anchor" href="#appimage">AppImage</a></h3>
+<p>The AppImage does not require a conventional installation.</p>
+<ol>
+<li>Download <code>KST4Contest-v&lt;version&gt;-linux-x86_64.AppImage</code>.</li>
+<li>Open a terminal in the download directory.</li>
+<li>Make the file executable:</li>
+</ol>
+<pre><code class="language-bash">chmod +x KST4Contest-v&lt;version&gt;-linux-x86_64.AppImage
+</code></pre>
+<ol start="4">
+<li>Start KST4Contest:</li>
+</ol>
+<pre><code class="language-bash">./KST4Contest-v&lt;version&gt;-linux-x86_64.AppImage
+</code></pre>
+<p>The AppImage can then be moved to another location, such as <code>~/Applications</code>.</p>
+<h3 id="debian-and-ubuntu" tabindex="-1"><a class="header-anchor" href="#debian-and-ubuntu">Debian and Ubuntu</a></h3>

+<p>AUR updates are included when the selected AUR helper checks for package updates, for example:</p>
+<pre><code class="language-bash">yay -Syu
+</code></pre>

+<p>KST4Contest stores its settings and other local working files in the user’s home directory. The application directory and the data directory are separate.</p>

+<h2 id="updates" tabindex="-1"><a class="header-anchor" href="#updates">Updates</a></h2>
+<p>When KST4Contest starts, it checks whether a newer Stable release is available. If it finds one, it displays an information window containing:</p>

+<p>KST4Contest is not currently signed with a commercial Windows code-signing certificate. Windows or an additional security product may therefore warn about an unknown or rarely downloaded application.</p>
+<p>Check the following first:</p>
+<ul>
+<li>Did the file come from the <a href="https://github.com/praktimarc/kst4contest/releases/latest">official KST4Contest release</a>?</li>
+<li>Does the filename match the published release?</li>
+<li>Was the file downloaded completely?</li>
+<li>Does the security product report a specific detection name or only a general reputation warning?</li>
+</ul>
+<p>A warning alone is neither reliable proof of malware nor automatically a false positive. If the origin of the file is unclear, do not run it or restore it from quarantine.</p>
+<p>Some users have reported quarantine messages from Norton 360 in particular. If the warning can be reproduced, please create a <a href="https://github.com/praktimarc/kst4contest/issues">GitHub issue</a> and include:</p>
+<ul>
+<li>the KST4Contest version,</li>
+<li>the complete filename,</li>
+<li>the security product and its version,</li>
+<li>the reported detection name,</li>
+<li>a screenshot of the warning, if possible.</li>
+</ul>
+<h3 id="the-appimage-does-not-start" tabindex="-1"><a class="header-anchor" href="#the-appimage-does-not-start">The AppImage does not start</a></h3>
+<p>Check the executable permission first:</p>
+<pre><code class="language-bash">chmod +x KST4Contest-v&lt;version&gt;-linux-x86_64.AppImage
+</code></pre>
+<p>Then start the file from a terminal. Error messages shown there are usually more useful than a double-click that simply produces no visible result.</p>
+<h3 id="macos-blocks-the-application" tabindex="-1"><a class="header-anchor" href="#macos-blocks-the-application">macOS blocks the application</a></h3>
+<p>Use the <strong>Open</strong> function described under <a href="#installing-on-macos">Installing on macOS</a>. Before doing so, verify that the DMG file came from the official GitHub Release.</p>
+<h3 id="the-problem-remains" tabindex="-1"><a class="header-anchor" href="#the-problem-remains">The problem remains</a></h3>
+<p>First check whether the problem has already been reported under <a href="https://github.com/praktimarc/kst4contest/issues">GitHub Issues</a>. If it has not, create a new issue containing:</p>
+<ul>
+<li>the operating system and version,</li>
+<li>the KST4Contest version,</li>
+<li>the installation method,</li>
+<li>the exact error message,</li>
+<li>the steps required to reproduce the problem.</li>
+</ul>
+<p>“It does not work” usually describes the situation accurately, but it is of limited value during diagnosis.</p>

+<blockquote>
+<p>🇬🇧 You are reading the English version | 🇩🇪 <a href="/manual/de/log-synchronisation/">Deutsche Version</a></p>
+</blockquote>
+<p>KST4Contest automatically marks worked stations in the chat user list. Two basic methods are available:</p>
+<hr>
+<p><img src="/manual/assets/client_settings_window_logsync.png" alt="Log Sync Settings Window"></p>
+<h2 id="method-1%3A-universal-file-based-callsign-interpreter-(simplelogfile)" tabindex="-1"><a class="header-anchor" href="#method-1%3A-universal-file-based-callsign-interpreter-(simplelogfile)">Method 1: Universal File Based Callsign Interpreter (Simplelogfile)</a></h2>
+<p>KST4Contest reads a log file and searches for callsign patterns using a regular expression. Binary log files are also supported – unreadable binary content is simply ignored.</p>
+<p><strong>Advantage</strong>: Works with almost any logging program that writes a file.
+<strong>Disadvantage</strong>: No band information available – stations are only marked as “worked”, not on which band.</p>
+<p>Enter the path to the log file in the Preferences. The file is only read, never modified (read-only).</p>
+<blockquote>
+<p><strong>Tip</strong>: The Simplelogfile function can also be used to mark stations that are definitely unreachable (e.g. personal notes). This will be replaced in a later version by a better tagging system.</p>
+</blockquote>
+<hr>
+<h2 id="method-2%3A-network-listener-(udp-broadcast)-%E2%80%93-recommended" tabindex="-1"><a class="header-anchor" href="#method-2%3A-network-listener-(udp-broadcast)-%E2%80%93-recommended">Method 2: Network Listener (UDP Broadcast) – Recommended</a></h2>
+<p>When saving a QSO, the logging software sends a UDP packet to the broadcast address of the home network. KST4Contest receives this packet and marks the station including <strong>band information</strong> in its internal SQLite database.</p>
+<blockquote>
+<p><strong>Important</strong>: KST4Contest must be <strong>running in parallel with the logging software</strong>. QSOs logged while KST4Contest is not running will not be captured – except with QARTest (which can send the complete log).</p>
+</blockquote>
+<p><strong>Default UDP port</strong>: 12060 (matches the default of most logging programs)</p>

+<h3 id="ucxlog-(dl7ucx)" tabindex="-1"><a class="header-anchor" href="#ucxlog-(dl7ucx)">UCXLog (DL7UCX)</a></h3>
+<p><img src="/manual/assets/ucxlog_logsync.png" alt="UCXLog Configuration"></p>
+<p>UCXLog sends QSO UDP packets and transceiver frequency packets.</p>
+<p><strong>Settings in UCXLog:</strong></p>
+<ul>
+<li>Enable UDP broadcast</li>
+<li>Enter the IP address of the KST4Contest computer (for local operation: <code>127.0.0.1</code>)</li>
+<li>Port: 12060 (default)</li>
+</ul>
+<p>Note the green-highlighted fields in the UCXLog settings: IP and port must be filled in.</p>
+<p>Note for multi-setup (2 computers, 2 radios, one KST4Contest instance): Both logging programs must send QSO packets to the IP of the KST4Contest computer. In this case, at least one IP is not <code>127.0.0.1</code>.</p>
+<h3 id="qartest-(ik3qar)" tabindex="-1"><a class="header-anchor" href="#qartest-(ik3qar)">QARTest (IK3QAR)</a></h3>
+<p><img src="/manual/assets/qartest_logsync.png" alt="QARTest Configuration"></p>
+<p><strong>Special feature</strong>: QARTest can send the <strong>complete log</strong> to KST4Contest (button “Invia log completo” in the QARTest settings). This means QSOs logged before KST4Contest was started are also captured.</p>
+<p><strong>Settings in QARTest:</strong></p>
+<ul>
+<li>Configure UDP broadcast and IP/port as with UCXLog</li>
+<li>Use “Invia log completo” for a full log upload</li>

+<h3 id="n1mm%2B" tabindex="-1"><a class="header-anchor" href="#n1mm%2B">N1MM+</a></h3>
+<p><strong>Settings in N1MM+:</strong></p>
+<p>In N1MM+ under <code>Config → Configure Ports, Mode Control, Winkey, etc. → Broadcast Data</code>:</p>
+<ul>
+<li>Enable <code>Radio Info</code> (for TRX sync / QRG)</li>
+<li>Enable <code>Contact Info</code> (for QSO sync)</li>
+<li>IP: <code>127.0.0.1</code> (or IP of the KST4Contest computer)</li>
+<li>Port: 12060</li>
+</ul>
+<p>For the built-in DX cluster server: configure N1MM+ as a DX cluster client (server: <code>127.0.0.1</code>, port as set in KST4Contest).</p>
+<h3 id="dxlog.net" tabindex="-1"><a class="header-anchor" href="#dxlog.net"><a href="http://DXLog.net">DXLog.net</a></a></h3>
+<p><img src="/manual/assets/dxlog_net_logsync.png" alt="DXLog.net Configuration"></p>
+<p><strong>Settings in <a href="http://DXLog.net">DXLog.net</a>:</strong></p>
+<ul>
+<li>Enable UDP broadcast</li>

+<li>Port: 12060</li>
+</ul>
+<h3 id="win-test" tabindex="-1"><a class="header-anchor" href="#win-test">Win-Test</a></h3>
+<p>Win-Test is supported with a dedicated UDP network listener that understands the native Win-Test network protocol.</p>
+<p><strong>Advantages of Win-Test Integration:</strong></p>
+<ul>
+<li>Automatic QSO synchronization to mark worked stations.</li>
+<li><strong>Sked Handover (ADDSKED):</strong> Using the “Create sked” button in the station info panel not only creates a sked in KST4Contest but also <em>sends it directly via UDP to the Win-Test network as an ADDSKED packet</em> – automatically, as soon as the listener is active. No separate toggle is needed.</li>
+<li>You can choose between “AUTO”, “SSB”, or “CW” sked modes.</li>
+<li><strong>Automatic QRG resolution for SKEDs:</strong> KST4Contest selects the sked frequency intelligently:
+<ol>
+<li>If the other station mentioned their QRG in a recent chat message, that frequency is used.</li>
+<li>Otherwise, your own current QRG is used (from Win-Test STATUS or manual entry).</li>
+</ol>
+</li>
+</ul>
+<p><strong>Settings in the “Log Synchronisation” tab:</strong></p>
+<ul>
+<li>Enable <code>Receive Win-Test network based UDP log messages</code>.</li>
+<li><code>UDP-Port for Win-Test listener</code> (default: 9871).</li>
+<li><code>KST station name in Win-Test network (src of SKED packets)</code>: Defines the station name KST4Contest uses in the WT network (e.g. “KST”).</li>
+<li><code>Win-Test network broadcast address</code>: Usually detected automatically; required to send sked packets to the network.</li>
+</ul>
+<p><strong>Settings in the “TRX Synchronisation” tab:</strong></p>
+<ul>
+<li><code>Win-Test STATUS QRG Sync</code>: When enabled, KST4Contest takes the current transceiver frequency from the Win-Test STATUS packet and uses it as your own QRG (MYQRG).</li>
+<li><code>Use pass frequency from Win-Test STATUS</code>: Instead of the main TRX frequency, the pass frequency contained in the STATUS packet is used as MYQRG (useful for multi-op setups that operate with a dedicated pass QRG).</li>
+<li><code>Win-Test station name filter</code>: If a name is entered here (e.g. “STN1”), KST4Contest only processes packets from that specific Win-Test instance. Leave empty to accept all.</li>
+</ul>
+<p><strong>Settings in Win-Test:</strong></p>
+<ul>
+<li>The network in Win-Test must be active.</li>
+<li>Win-Test must be configured to send/receive its broadcasts on the corresponding port (default 9871).</li>
+</ul>
+<hr>
+<h2 id="trx-frequency-synchronisation" tabindex="-1"><a class="header-anchor" href="#trx-frequency-synchronisation">TRX Frequency Synchronisation</a></h2>
+<p>In addition to QSO synchronisation, UCXLog and other programs also transmit the <strong>current transceiver frequency</strong> via UDP. KST4Contest processes this information and makes it available as the <code>MYQRG</code> variable.</p>
+<p><img src="/manual/assets/qrg_buttons.png" alt="Frequency Buttons"></p>
+<p><strong>Result</strong>: Your own QRG never needs to be typed manually in the chat – clicking the MYQRG button or using the variable in the beacon is sufficient.</p>
+<p><strong>Sources for your own QRG (MYQRG):</strong></p>
+<ul>
+<li>UCXLog, N1MM+, <a href="http://DXLog.net">DXLog.net</a>, QARTest via UDP port 12060</li>
+<li>Win-Test STATUS packet (optional, configurable in the “TRX Synchronisation” tab under “Win-Test STATUS QRG Sync”)</li>
+<li>Manual entry in the QRG field</li>
+</ul>
+<blockquote>
+<p><strong>Note for multi-setup</strong>: With two logging programs on two computers, only <strong>one</strong> should send frequency packets. KST4Contest cannot distinguish between sources and processes all incoming packets.</p>
+</blockquote>

+<h2 id="multi-setup%3A-2-radios%2C-2-computers" tabindex="-1"><a class="header-anchor" href="#multi-setup%3A-2-radios%2C-2-computers">Multi-Setup: 2 Radios, 2 Computers</a></h2>
+<p>For DM5M-style setups (2 radios, 2 computers, one KST4Contest instance or two separate):</p>
+<p><strong>Option A – One shared KST4Contest instance:</strong></p>
+<ul>
+<li>Both logging programs send QSO packets to the IP of the KST4Contest computer</li>
+<li>Only one logging program sends frequency packets (recommended: the VHF logging program)</li>
+</ul>
+<p><strong>Option B – Two separate KST4Contest instances (recommended):</strong></p>
+<ul>
+<li>Each logging program communicates with its own KST4Contest instance via <code>127.0.0.1</code></li>
+<li>Two separate chat logins</li>
+<li>Better separation and fewer conflicts</li>
+</ul>
+<hr>
+<h2 id="internal-database" tabindex="-1"><a class="header-anchor" href="#internal-database">Internal Database</a></h2>
+<p>KST4Contest stores worked information in an internal <strong>SQLite database</strong>. This is independent of the logging program’s database and is only populated via the UDP broadcast.</p>

+<p>KST4Contest offers a flexible system of text snippets, shortcuts and built-in variables that significantly speed up the chat workflow during contests.</p>

+<hr>
+<h2 id="shortcuts-(quick-access-buttons)" tabindex="-1"><a class="header-anchor" href="#shortcuts-(quick-access-buttons)">Shortcuts (Quick-Access Buttons)</a></h2>
+<p>Configurable in Preferences → <strong>Shortcut Settings</strong>.</p>
+<ul>
+<li>Each configured text creates <strong>one button</strong> in the user interface.</li>
+<li>Clicking a button inserts the text into the <strong>send field</strong>.</li>
+<li><strong>All variables</strong> can be used in shortcuts and are resolved immediately when inserted.</li>
+<li>Longer texts are also possible.</li>
+</ul>
+<p><strong>Tip</strong>: Set up frequently used abbreviations like “pse”, “rrr”, “tnx”, “73” as shortcuts.</p>
+<hr>
+<h2 id="snippets-(text-building-blocks)" tabindex="-1"><a class="header-anchor" href="#snippets-(text-building-blocks)">Snippets (Text Building Blocks)</a></h2>
+<p>Configurable in Preferences → <strong>Snippet Settings</strong>.</p>
+<h3 id="access" tabindex="-1"><a class="header-anchor" href="#access">Access</a></h3>
+<ul>
+<li><strong>Right-click</strong> on a callsign in the user list</li>
+<li><strong>Right-click</strong> in the CQ message table</li>
+<li><strong>Right-click</strong> in the PM message table</li>
+<li><strong>Keyboard shortcuts</strong>: <code>Ctrl+1</code> to <code>Ctrl+0</code> for the first 10 snippets</li>
+</ul>
+<h3 id="behaviour-with-a-selected-callsign" tabindex="-1"><a class="header-anchor" href="#behaviour-with-a-selected-callsign">Behaviour with a Selected Callsign</a></h3>
+<p>When a callsign is selected in the user list, the snippet is addressed as a <strong>private message</strong>:</p>
+<pre><code>/CQ CALLSIGN &lt;snippet text&gt;
+</code></pre>
+<p>Then <strong>Enter</strong> can be pressed to send directly – even if the send field does not have focus.</p>
+<h3 id="hardware-macro-keyboard" tabindex="-1"><a class="header-anchor" href="#hardware-macro-keyboard">Hardware Macro Keyboard</a></h3>
+<p><em>(Idea by IU3OAR, Gianluca Costantino)</em></p>
+<p>The key combinations <code>Ctrl+1</code> to <code>Ctrl+0</code> can be assigned to a programmable macro keyboard. One key press triggers the snippet, another press (mapped to Enter) sends it immediately. In contest operation this saves considerable time.</p>
+<h3 id="predefined-default-snippets" tabindex="-1"><a class="header-anchor" href="#predefined-default-snippets">Predefined Default Snippets</a></h3>
+<p>On first start, some snippets are pre-configured, e.g.:</p>
+<ul>
+<li><code>Hi OM, try sked?</code></li>
+<li><code>I am calling cq ur dir, pse lsn to me at MYQRG</code></li>
+<li><code>pse ur qrg?</code></li>
+<li><code>rrr, I move to your qrg nw, pse ant dir me</code></li>
+</ul>
+<p>These can be customised or deleted in the Preferences.</p>
+<hr>
+<h2 id="variables" tabindex="-1"><a class="header-anchor" href="#variables">Variables</a></h2>
+<p>Variables in written texts (snippets, shortcuts, beacon, send field) are replaced by their current values at runtime. Simply type the variable name in <strong>uppercase</strong> in the text.</p>
+<h3 id="myqrg" tabindex="-1"><a class="header-anchor" href="#myqrg">MYQRG</a></h3>
+<p>Replaced by the current transceiver frequency.</p>
+<ul>
+<li>Source: TRX sync via UDP from the logging software (if enabled)</li>
+<li>Fallback: Manually entered value in the MYQRG text field to the right of the send button</li>
+<li>Format: <code>144.388.03</code></li>
+</ul>
+<p><strong>Example</strong>: <code>calling cq at MYQRG</code> → <code>calling cq at 144.388.03</code></p>
+<h3 id="myqrgshort" tabindex="-1"><a class="header-anchor" href="#myqrgshort">MYQRGSHORT</a></h3>
+<p>Like MYQRG, but only the first 7 characters.</p>
+<ul>
+<li>Format: <code>144.388</code></li>
+</ul>
+<p><strong>Example</strong>: <code>qrg: MYQRGSHORT</code> → <code>qrg: 144.388</code></p>
+<h3 id="mylocator" tabindex="-1"><a class="header-anchor" href="#mylocator">MYLOCATOR</a></h3>
+<p>Replaced by your own Maidenhead locator (6 characters).</p>
+<ul>
+<li>Format: <code>JO51IJ</code></li>
+</ul>
+<p><strong>Example</strong>: <code>my loc: MYLOCATOR</code> → <code>my loc: JO51IJ</code></p>
+<h3 id="mylocatorshort" tabindex="-1"><a class="header-anchor" href="#mylocatorshort">MYLOCATORSHORT</a></h3>
+<p>Like MYLOCATOR, but only the first 4 characters.</p>
+<ul>
+<li>Format: <code>JO51</code></li>
+</ul>
+<p><strong>Example</strong>: <code>loc: MYLOCATORSHORT</code> → <code>loc: JO51</code></p>
+<h3 id="qrzname" tabindex="-1"><a class="header-anchor" href="#qrzname">QRZNAME</a></h3>
+<p>Replaced by the <strong>name</strong> of the currently selected station from the chat name field.</p>
+<p><strong>Example</strong>: <code>Hi QRZNAME, sked?</code> → <code>Hi Gianluca, sked?</code></p>
+<h3 id="firstap" tabindex="-1"><a class="header-anchor" href="#firstap">FIRSTAP</a></h3>
+<p>Replaced by data of the first reflectable aircraft to the selected station (if available).</p>
+<ul>
+<li>Condition: AirScout is active and an aircraft is available.</li>
+<li>Example format: <code>a very big AP in 1 min</code></li>
+</ul>
+<p><strong>Example</strong>: <code>AP info: FIRSTAP</code> → <code>AP info: a very big AP in 1 min</code></p>
+<h3 id="secondap" tabindex="-1"><a class="header-anchor" href="#secondap">SECONDAP</a></h3>
+<p>Like FIRSTAP, but for the second available aircraft.</p>
+<ul>
+<li>Example format: <code>Next big AP in 9 min</code></li>
+</ul>
+<p><strong>Example</strong>: <code>also: SECONDAP</code> → <code>also: Next big AP in 9 min</code></p>
+<h3 id="myqtf-(planned-for-v1.3)" tabindex="-1"><a class="header-anchor" href="#myqtf-(planned-for-v1.3)">MYQTF <em>(planned for v1.3)</em></a></h3>
+<p>Replaced by the current antenna direction in words (e.g. <code>north</code>, <code>north east</code>, <code>east</code>, …).</p>
+<ul>
+<li>Source: Degree value in the MYQTF input field (to the right of the MYQRG field)</li>
+</ul>
+<hr>
+<h2 id="variables-in-the-beacon" tabindex="-1"><a class="header-anchor" href="#variables-in-the-beacon">Variables in the Beacon</a></h2>
+<p>All variables can also be used in the <strong>automatic beacon</strong> (interval messages). Recommended beacon configuration:</p>
+<pre><code>calling cq at MYQRG, loc MYLOCATOR, GL all!
+</code></pre>
+<p>Since KST4Contest automatically reads QRG data from chat messages: if other stations also use KST4Contest, they will immediately see your QRG in the QRG column of their user list.</p>
+<hr>
+<h2 id="example-contest-workflow-with-macros" tabindex="-1"><a class="header-anchor" href="#example-contest-workflow-with-macros">Example Contest Workflow with Macros</a></h2>
+<ol>
+<li>Select a station in the user list → callsign is now pre-selected.</li>
+<li>Press <code>Ctrl+1</code> → Snippet “Hi OM, try sked?” is addressed as a PM.</li>
+<li>Press Enter → Message sent.</li>
+<li>Station replies with frequency → QRG column is automatically filled.</li>
+<li>Press <code>Ctrl+2</code> → Snippet “I am calling cq ur dir, pse lsn to me at 144.388” (MYQRG resolved).</li>
+<li>Press Enter → Sent.</li>
+</ol>
+<p>No manual typing, no errors, no interruption to CQ calling.</p>

Copilot Claude Sonnet 5 Rsclub2_2	7d3177ba8a	Add selected-band activity indicator for stations in map and details (#53 ) * Initial plan * Add map indicator for selected-band activity hints * Add selected-band marker to main station table * Move band-offer star from callsign to worked status cell * Move band-offer star from wkdany column to per-band worked cells Fixes a bad merge that had nested a method definition inside another method (broke compilation), and relocates the new-band-opportunity star so it appears on the specific band cell it applies to instead of a single generic wkdany column, since a station can offer several bands at once. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * Changed Indicator to B+ instead of star for better understandability --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Philipp Wagner <philipp@wagnersnetz.de> Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>	2026-07-08 22:32:54 +02:00
