-Die QRG-Spalte zeigt die zuletzt für eine Station erkannte Frequenz. Fehlende Nullen werden für die Anzeige ergänzt, sodass beispielsweise `144.21` als `144.210` erscheint. Erkennt KST4Contest nacheinander Frequenzen auf mehreren Bändern, zeigt die Spalte den letzten Treffer; die internen Bandinformationen können trotzdem mehrere aktuelle Bänder der Station enthalten.
-
-Relative Angaben werden zunächst mit einem höchstens 30 Minuten alten Bandkontext desselben Absenders kombiniert. Nur wenn dieser fehlt, verwendet KST4Contest das globale Fallback-Band. Erkennungsregeln, Beispiele und Grenzen: [QRG-Erkennung](de-Funktionen#qrg-erkennung).
-
-### Worked-, Band- und Großfeldstatus
-
-Die Unterspalten unter **worked** sind kompakt, weil bei mehreren aktivierten Bändern kaum Platz für ausgeschriebene Zustände bleibt. `X` kennzeichnet ein auf diesem Band gearbeitetes Rufzeichen. `a` und `B+` weisen auf ein angebotenes, noch nicht gearbeitetes Band hin. Ein angehängtes `o` bedeutet, dass das vierstellige Großfeld auf diesem Band bereits gearbeitet wurde.
-
-Die Unterspalte **wkdany** ist bandunabhängig: `x` steht für ein bereits gearbeitetes Rufzeichen, `o` für ein auf irgendeinem Band gearbeitetes Großfeld und `xo` für beides.
-
-Jede Statuszelle besitzt einen Tooltip mit der Legende und dem für die betreffende Station ermittelten Zustand. Die vollständige Herleitung einschließlich NOT-QRV-Vorrang: [Gearbeitete Rufzeichen, neue Bänder und neue Großfelder](de-Funktionen#gearbeitete-rufzeichen-neue-bänder-und-neue-großfelder).

-KST4Contest zeigt Nachrichtentexte bewusst einzeilig an. So bleiben auch bei hohem Chat-Aufkommen viele Einträge gleichzeitig sichtbar. Der Nachteil liegt auf der Hand: Bei einer schmalen **Message**-Spalte passt nicht jede Nachricht vollständig in die Zeile.
-
-Ist ein Nachrichtentext breiter als die sichtbare Zelle, zeigt KST4Contest den vollständigen Inhalt als Tooltip an. Dazu die Maus kurz über die betreffende **Message**-Zelle halten. Passt der Text vollständig in die Spalte, wird kein zusätzlicher Volltext-Tooltip eingeblendet.
-
-Webadressen mit `http://`, `https://` oder dem Präfix `www.` werden innerhalb des Nachrichtentextes als Links dargestellt. Ein Klick öffnet die Adresse im Standardbrowser des Betriebssystems. Andere Protokolle werden nicht als Link behandelt.
-

 ## Filter
 
-Die Filterleiste befindet sich oberhalb der Chatmember-Tabelle. Sie ist in mehrere logisch zusammengehörige Bereiche gegliedert:
+Die Filter-Leiste (ab v1.21 als Flowpane für kleine Bildschirme):
 
-- **Show only QTF** begrenzt die Liste auf eine gewählte Antennenrichtung.
-- **Show only QRB [km] <=** setzt eine maximale Entfernung.
-- **Find** sucht nach einem Rufzeichen.
-- **wkd** blendet Rufzeichen aus, die bereits auf mindestens einem Band gearbeitet wurden.
-- Die einzelnen Band-Schaltflächen blenden eine Station aus, wenn sie auf dem betreffenden Band bereits gearbeitet oder dort als NOT QRV markiert wurde. Angezeigt werden nur die für die eigene Station aktivierten Bänder.
-- **Only new grids** zeigt ausschließlich Stationen aus vierstelligen Großfeldern, die auf noch keinem Band gearbeitet wurden.
-- **Grid color** ist kein Filter. Die Funktion markiert das QRA-Feld bereits gearbeiteter Großfelder, ohne Stationen auszublenden.
-- **New bands** zeigt Stationen mit mindestens einer erkannten, an der eigenen Station aktivierten und noch nicht gearbeiteten Bandmöglichkeit. NOT-QRV-Markierungen haben Vorrang.
-- **Reachability**, **Tropo >=0dB** und **AS next 5m** schränken die Liste anhand der gewählten Strecken- beziehungsweise AirScout-Bedingungen ein.
+- **Show only QTF**: Richtungsfilter aktivieren (Buttons N/NE/E/… oder Grad-Eingabe)
+- **Show only QRB [km] <=**: Entfernungsfilter aktivieren (Toggle-Button)
+- **Hide Worked [Band]**: Gearbeitete Stationen pro Band ausblenden (je ein Toggle pro Band)
+- **Hide NOT-QRV [Band]**: NOT-QRV-markierte Stationen pro Band ausblenden
 
-Die Filterleiste besitzt keine feste Breite. QTF sowie die Worked- und Reachability-Filter nutzen zunächst den gesamten Platz ihrer jeweiligen Zeile. Wird der horizontale Divider nach rechts verschoben und die Chatmember-Ansicht dadurch schmaler, wechseln die Controls erst dann in die nächste Zeile, wenn ihre tatsächlich benötigte Breite nicht mehr zur Verfügung steht.
-
-![Umgebrochene Filterleiste bei schmaler Chatmember-Ansicht](filter_bar_wrapped.png)
-
-Im Klartext: Die Filter bestimmen weiterhin den Inhalt der Tabelle, aber nicht mehr die Mindestbreite der gesamten rechten Programmseite. In der normalen Ansicht bleibt die Leiste kompakt. Erst bei einer tatsächlich schmalen Ansicht benötigt sie mehr Höhe. Der Divider kann anschließend wieder nach links verschoben werden; die Controls ordnen sich unmittelbar neu an.

+*(Idee von OM0AAO, Viliam Petrik – danke!)*
 
 ---
 
-## Warum überhaupt ein eigener DX-Cluster-Server?
+## Wozu dient der integrierte DX-Cluster-Server?
 
-Eine interessante Frequenz im Chat zu erkennen ist nur der erste Schritt. Im Contest muss diese Information dort ankommen, wo sie unmittelbar verwendet werden kann: im Logprogramm und dessen Bandmap.
+Wenn KST4Contest erkennt, dass eine Station aus der eigenen Richtung ein Sked anfragt und gleichzeitig eine QRG bekannt ist, wird **automatisch ein DX-Cluster-Spot generiert** und an den Cluster-Client des Logprogramms gesendet.
 
-KST4Contest verbindet deshalb zwei bereits vorhandene Informationen:
-
-1. Aus einer gerichteten Chat-Nachricht lässt sich abschätzen, in welche Richtung die sendende Station ihre Antenne wahrscheinlich ausgerichtet hat.
-2. Aus derselben oder einer vorherigen Nachricht kann eine Frequenz der Station bekannt sein.
-
-Treffen beide Informationen zusammen, erzeugt KST4Contest einen lokalen DX-Cluster-Spot. Der Logger kann diesen Spot in seiner Bandmap anzeigen und – abhängig von seiner eigenen Konfiguration – den Transceiver nach einem Klick auf die entsprechende Frequenz einstellen.
-
-Im Klartext: Die Information muss nicht erst im Chat gefunden, gelesen, gemerkt und anschließend erneut in den Logger eingetragen werden. Genau diese kleinen Unterbrechungen kosten im Contest überraschend viel Aufmerksamkeit.
+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.
 
 ---
 
-## Wie wird eine Richtungsgelegenheit hergeleitet?
+## Einrichtung
 
-Angenommen, Station A schreibt eine gerichtete Nachricht an Station B. KST4Contest verwendet die Richtung von A zu B als Näherung für die aktuelle Antennenrichtung von Station A. Anschließend wird geprüft, ob die eigene Station aus Sicht von A innerhalb des angenommenen Antennenkorridors liegt.
+### In KST4Contest
 
-Dafür werden zwei Richtungen verglichen:
+In den Preferences → **DX-Cluster-Server-Einstellungen**:
 
-- die Richtung von Station A zu Station B,
-- die Richtung von Station A zur eigenen Station.
+1. **Port** des internen Servers eintragen (z. B. 7300 oder 8000 – muss mit dem Logprogramm übereinstimmen).
+2. **Spotter-Rufzeichen** eintragen – **unbedingt ein anderes Rufzeichen als das Contest-Rufzeichen verwenden!**
+   - Grund: Logprogramme filtern Spots, die vom eigenen Rufzeichen stammen, als „gearbeitet" heraus. Wenn der Spotter dasselbe Rufzeichen hat, werden die Spots nicht angezeigt.
+3. **Angenommene MHz** eintragen: Bei Frequenzangaben wie „.205" 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" oder „1296.338" im Chat werden immer korrekt erkannt.
 
-Der in den Station Settings konfigurierte Antennen-Öffnungswinkel ist der vollständige Winkel. Für die Prüfung wird jeweils die Hälfte links und rechts der Richtung A → B angesetzt. Bei `70°` sind das somit `±35°`.
+### In UCXLog
 
-Da ON4KST keine Antennendaten der fremden Station überträgt, verwendet KST4Contest den Öffnungswinkel der eigenen Antenne zugleich als Näherung für Station A. Das ist keine Messung der tatsächlichen Antennenrichtung, sondern eine bewusst einfache geometrische Annahme.
+- Verbindung zu einem DX-Cluster-Server konfigurieren:
+  - Host: `127.0.0.1` (oder IP des KST4Contest-Computers)
+  - Port: Wie in KST4Contest konfiguriert
+  - Passwort: kann leer bleiben
+- Über die Schaltfläche **„Send a test message to your log"** kann die Verbindung getestet werden.
 
-Ein DX-Cluster-Spot wird nur erzeugt, wenn alle folgenden Bedingungen erfüllt sind:
+### In N1MM+
 
-1. Eine gerichtete Nachricht wurde zwischen zwei anderen Stationen erkannt.
-2. Für Absender und Empfänger sind gültige Locator bekannt.
-3. Der Absender liegt innerhalb des konfigurierten maximalen QRB zur eigenen Station.
-4. Die eigene Station liegt aus Sicht des Absenders innerhalb des angenommenen Antennenkorridors.
-5. Für den Absender ist eine verwertbare Frequenz bekannt oder in der aktuellen Nachricht erkannt worden.
-6. Der lokale DX-Cluster-Server ist aktiviert.
-
-Treffen die Bedingungen zu, wird der Spot unmittelbar beim Verarbeiten der Nachricht erzeugt. Die parallel angezeigte grüne Richtungsmarkierung bleibt dagegen fünf Minuten sichtbar und kann durch spätere Nachrichten verlängert oder vorzeitig entfernt werden.
-
-Das Verfahren berücksichtigt weder Gelände noch aktuelle Ausbreitungsbedingungen und beweist keine tatsächliche Antennenstellung. Es erkennt eine plausible Gelegenheit. Die ausführliche Herleitung und ein Zahlenbeispiel stehen unter [Richtungsgelegenheiten aus gerichteten Nachrichten](de-Funktionen#richtungsgelegenheiten-aus-gerichteten-nachrichten).

-## Welche Frequenz wird verwendet?
+## Funktionsweise
 
-Ein DX-Cluster-Spot benötigt eine eindeutige Frequenz. KST4Contest verwendet dafür dieselbe QRG-Erkennung wie die Benutzerliste und die übrigen bandbezogenen Funktionen.
+Ein Spot wird generiert, wenn **beide** Bedingungen erfüllt sind:
 
-Vollständige Frequenzen bestimmen ihr Band direkt:
+1. Eine **Richtungs-Warnung** wurde ausgelöst (Station macht ein Sked in die eigene Richtung).
+2. **QRG der Station ist bekannt** (aus dem Chat ausgelesen oder manuell eingetragen).
 
-```text
-144.205
-432,088
-1296.338
-10368.100
-```
+Der generierte Spot enthält:
+- Rufzeichen der Station
+- Frequenz
+- Spotterzeit
 
-Relative Angaben enthalten dagegen nur den Frequenzanteil innerhalb eines Bandes:
-
-```text
-.205
-,205
-qrg 205
-freq is 205
-on 205
-205 MHz
-```
-
-Eine nackte dreistellige Zahl wie `205` wird ohne Frequenzkontext nicht ausgewertet. Dasselbe gilt für `599`, `144` oder Formulierungen wie `worked 210 stations`. So verhindert KST4Contest, dass Signalrapporte, Bandnamen oder Zählwerte als scheinbar plausible QRG gespeichert und später an den Logger weitergegeben werden.
-
-Bei einer relativen QRG wird das Band in dieser Reihenfolge bestimmt:
-
-1. KST4Contest prüft, ob für denselben Absender innerhalb der letzten 30 Minuten bereits ein passender Bandkontext bekannt wurde.
-2. Sind mehrere aktuelle Bänder bekannt, wird der zuletzt aktualisierte plausible Kontext verwendet.
-3. Erst wenn kein geeigneter Stationskontext vorhanden ist, verwendet KST4Contest das unter **Fallback band for relative QRG detection** ausgewählte Band.
-
-Beispiel:
-
-```text
-Globales Fallback: 144 MHz
-Letzte vollständige QRG der Station: 432.088 MHz
-Neue Chat-Angabe derselben Station: .100
-Erkannte QRG: 432.100 MHz
-DX-Cluster-Frequenz: 432100.0 kHz
-```
-
-Ohne den aktuellen 432-MHz-Kontext würde dieselbe Angabe mit dem globalen Fallback zu `144.100 MHz` ergänzt.
-
-Die QRG-Erkennung läuft vor der Richtungs- und Spotprüfung. Nennt eine Station ihre Frequenz erstmals in der gerichteten Nachricht, die zugleich eine Richtungsgelegenheit auslöst, kann bereits der daraus erzeugte Spot diese Frequenz enthalten. War zuvor eine andere QRG der Station bekannt, wird sie durch die neu erkannte Angabe aktualisiert.
-
-Das Fallback-Band ist eine globale Einstellung der QRG-Erkennung. Seine Wirkung ist nicht auf den DX-Cluster beschränkt. Konfiguration, unterstützte Bänder und weitere Folgen sind unter [Fallback-Band für relative QRG-Erkennung](de-Konfiguration#fallback-band-für-relative-qrg-erkennung) beschrieben.
+Das Logprogramm kann den Spot dann in der Bandkarte anzeigen und den TRX per Mausklick auf die Frequenz abstimmen.

-
-Konfiguriere anschließend:
-
-1. **Enable the local DX Cluster server …** aktivieren.
-2. Einen freien **TCP port** eintragen. Standard ist `8000`.
-3. Unter **Fallback band for relative QRG detection** das passende Band auswählen.
-4. Ein **Spotter callsign** festlegen.
-
-Für das Spotter-Rufzeichen sollte nach Möglichkeit ein anderes Rufzeichen als das Contest-Rufzeichen verwendet werden. Einige Logger filtern Spots, die scheinbar von der eigenen Station stammen. Das Ergebnis wäre technisch korrekt erzeugt, aber in der Bandmap trotzdem unsichtbar – eine besonders unproduktive Art von Erfolg.
-
-Änderungen am Aktivierungsstatus und am TCP-Port werden während einer laufenden Chat-Verbindung sofort angewendet. Bei einem Portwechsel werden vorhandene DX-Cluster-Verbindungen getrennt und müssen vom Logger neu aufgebaut werden.
-
-Die Einstellungen werden erst mit **Save Settings** dauerhaft in der `preferences.xml` gespeichert.

-## Einrichtung im Logprogramm
-
-Das Logprogramm wird als DX-Cluster-Client mit KST4Contest verbunden.
-
-| Einstellung | KST4Contest und Logger auf demselben Computer | Logger auf einem anderen Computer |
-|---|---|---|
-| Host | `127.0.0.1` | IP-Adresse des KST4Contest-Computers |
-| Port | In KST4Contest konfigurierter TCP-Port | In KST4Contest konfigurierter TCP-Port |
-| Login | Beliebiges Rufzeichen, falls der Logger eines verlangt | Beliebiges Rufzeichen, falls der Logger eines verlangt |
-| Passwort | Nicht erforderlich | Nicht erforderlich |
-
-KST4Contest wertet den vom Logger gesendeten Login nicht zur Authentifizierung aus. Die Verbindung ist für ein lokales oder vertrauenswürdiges Stationsnetz vorgesehen.
-
-Wenn der Logger auf einem anderen Computer läuft, muss dessen Verbindung durch die lokale Firewall des KST4Contest-Computers zugelassen werden. Der Port sollte nicht ohne weiteren Schutz aus dem Internet erreichbar sein.
-
-Mehrere DX-Cluster-Clients können gleichzeitig verbunden werden. Ein erzeugter Spot wird an alle aktuell verbundenen Clients gesendet.
-

-
-## Verbindung testen
-
-Die Schaltfläche **Send test spot** erzeugt einen neutralen Testeintrag:
-
-```text
-Spotted callsign: DO5AMF
-Comment: KST4CONTEST TEST
-Frequency: .300 des konfigurierten Fallback-Bandes
-```
-
-Bei einem Fallback-Band von `144` erscheint der Spot daher auf ungefähr `144.300 MHz`.
-
-Vor dem Test müssen drei Bedingungen erfüllt sein:
-
-1. KST4Contest ist mit dem ON4KST-Chat verbunden.
-2. Der lokale DX-Cluster-Server ist aktiviert.
-3. Der DX-Cluster-Client des Logprogramms ist mit KST4Contest verbunden.
-
-Fehlt die Client-Verbindung, zeigt KST4Contest eine entsprechende Meldung an. Ein erfolgreich ausgeführter Test bedeutet damit tatsächlich, dass mindestens ein Client den Spot erhalten hat.
-

-
-## Inhalt eines erzeugten Spots
-
-Ein Spot enthält:
-
-- das konfigurierte Spotter-Rufzeichen,
-- die normalisierte Frequenz,
-- das Rufzeichen der erkannten Station,
-- den Locator,
-- Flugzeug-Scatter-Informationen, falls vorhanden,
-- die aktuelle UTC-Zeit.
-
-Wenn für die Station aktuelle Aircraft-Scatter-Informationen vorliegen, kann KST4Contest diese als zusätzliche AP-Information in den Kommentar des Spots aufnehmen.
-
----
-
-## Wenn kein Spot erscheint
-
-### Der Testspot kommt nicht im Logger an
-
-Prüfe:
-
-- Ist KST4Contest mit dem Chat verbunden?
-- Ist der lokale DX-Cluster-Server aktiviert?
-- Verwendet der Logger denselben TCP-Port?
-- Verwendet der Logger bei lokalem Betrieb `127.0.0.1`?
-- Blockiert eine Firewall die Verbindung?
-- Ist im Logger das DX-Cluster-Fenster beziehungsweise die Bandmap aktiviert?
-
-### Testspot funktioniert, aber reale Spots fehlen
-
-Dann funktioniert die Verbindung grundsätzlich. Für die betreffende Chat-Situation war wahrscheinlich mindestens eine fachliche Bedingung nicht erfüllt:
-
-- kein gerichteter Nachrichtenaustausch,
-- fehlender Locator,
-- Station außerhalb des maximalen QRB,
-- Richtung außerhalb des konfigurierten Öffnungswinkels,
-- keine erkannte Frequenz.
-
-KST4Contest sendet absichtlich nicht jede gefundene Frequenz an den Logger. Andernfalls würde aus einer Arbeitserleichterung sehr schnell eine lokale Spot-Schleuder.
-
-### Der Spot erscheint auf dem falschen Band
-
-Prüfe zuerst, welche Frequenzen für die betreffende Station innerhalb der letzten 30 Minuten erkannt wurden. Bei einer relativen Angabe hat dieser Stationskontext Vorrang vor dem globalen Fallback.
-
-Ist kein aktueller Stationskontext vorhanden, prüfe die Auswahl unter **Fallback band for relative QRG detection**. Das Fallback wird nur benötigt, wenn sich das Band weder aus einer vollständigen Frequenz noch aus dem aktuellen Kontext des Absenders ergibt.
-
-### Der Spot wird vom Logger ausgeblendet
-
-Verwende ein Spotter-Rufzeichen, das nicht mit dem eigenen Contest-Rufzeichen identisch ist. Abhängig vom Logger können eigene Spots gefiltert oder besonders behandelt werden.

-## Richtungsgelegenheiten aus gerichteten Nachrichten
 
-Im ON4KST-Chat ist sichtbar, welche Station eine Nachricht an welche andere Station richtet. Eine tatsächliche Antennenrichtung wird dabei nicht übertragen. Für den Contestbetrieb lässt sich aus einer solchen Nachricht trotzdem eine brauchbare Annahme ableiten: Wer einen Sked anfragt, beantwortet oder vorbereitet, richtet seine Antenne normalerweise zumindest ungefähr auf die angesprochene Station.
+## Sked-Richtungs-Hervorhebung
 
-KST4Contest wertet deshalb gerichtete Nachrichten zwischen zwei anderen Stationen aus. Die Nachricht muss nicht ausdrücklich als Sked gekennzeichnet sein. Entscheidend sind der Absender, der Empfänger und deren Locator.
+Eine der Kernfunktionen: Wenn eine Station ein Sked in die **eigene Richtung** sendet, wird sie in der Benutzerliste **grün und fett** hervorgehoben.
 
-### Wie wird die Richtung hergeleitet?
+### Wie funktioniert das?
 
-Angenommen, Station A schreibt eine gerichtete Nachricht an Station B:
+Die Berechnung basiert auf folgender Logik:
 
-1. KST4Contest berechnet die Richtung von Station A zu Station B.
-2. Diese Richtung wird als wahrscheinliche Antennenrichtung von Station A verwendet.
-3. Anschließend wird die Richtung von Station A zur eigenen Station berechnet.
-4. Die Winkeldifferenz wird mit der Hälfte des konfigurierten Antennen-Öffnungswinkels verglichen.
-5. Zusätzlich muss Station A innerhalb des konfigurierten maximalen QRB liegen.
+- Wenn Station A eine Sked-Anfrage an Station B sendet, wird angenommen, dass A ihre Antenne auf B ausrichtet.
+- Wenn die daraus resultierende Richtung von A zur eigenen Station innerhalb des halben Öffnungswinkels der eigenen Antenne liegt, wird A hervorgehoben.
 
-Ein eingetragener Öffnungswinkel von `70°` ergibt damit einen angenommenen Korridor von jeweils `35°` links und rechts der Richtung von Station A zu Station B.
+**Beispiel** (Öffnungswinkel 69°, Halbwinkel 34,5°):
 
-| Beispiel | Ergebnis |
+| Situation | Ergebnis für DO5AMF in JN49 |
 |---|---|
-| Richtung A → B: `120°`, Richtung A → eigene Station: `145°` | Winkeldifferenz `25°`: Richtungsgelegenheit erkannt |
-| Richtung A → B: `120°`, Richtung A → eigene Station: `165°` | Winkeldifferenz `45°`: außerhalb des angenommenen Korridors |
-| Locator von A oder B fehlt | Keine Richtungsberechnung möglich |
-| A liegt außerhalb des maximalen QRB | Keine Richtungsgelegenheit |
+| Sked von F5FEN → DM5M | ✅ Hervorhebung (F5FEN zeigt Richtung DM5M, das liegt nahe JN49) |
+| Sked von DM5M → F5FEN | ✅ Hervorhebung (DM5M antwortet in Richtung F5FEN) |
+| F1DBN ist unbeteiligt | ❌ Keine Hervorhebung |
+| DO5AMF/P (anderer Standort) | ❌ Keine Hervorhebung für Sked-Antwort |
 
-### Was wird in der Benutzerliste angezeigt?
+Die Berechnung berücksichtigt keine topografischen Wegberechnungen – das ist eine bewusste Vereinfachung. Möglicherweise wird das in einer späteren Version ergänzt.
 
-Wird eine Richtungsgelegenheit erkannt, erscheint das Rufzeichen des Absenders in der Benutzerliste grün und fett. Im Evening-Modus wird dafür ein helleres Grün verwendet. Der Empfänger der Nachricht wird nicht allein deshalb markiert; eine Antwort in Gegenrichtung wird als eigene Nachricht und damit als neuer Fall berechnet.
-
-![Erkannte Richtungsgelegenheit in der Benutzerliste](direction_opportunity_highlight.png)
-
-Im Bild sendete DF0GEB eine gerichtete Nachricht an DN9APW und bekam eine Antwort. KST4Contest erkannte die Richtungsgelegenheit und markierte DN9APW in der Benutzerliste.
-Zur Verdeutlichung ist die MAP eingeblendet. Ich stehe als Empfänger zwischen beiden Stationen und bekomme deswegen die Warnung.
-
-Die Markierung bleibt fünf Minuten ab der letzten passenden Nachricht sichtbar. Eine weitere passende Nachricht derselben Station beginnt diesen Zeitraum erneut. Sendet die Station vorher eine gerichtete Nachricht, deren Richtung die Bedingungen nicht erfüllt, wird die Markierung unmittelbar entfernt.
-
-Ist die einfache Soundausgabe aktiviert, gibt KST4Contest beim erstmaligen Erkennen der Richtungsgelegenheit zusätzlich einen kurzen Hinweis aus. Solange die Station bereits markiert ist, wird derselbe Hinweis nicht mit jeder weiteren passenden Nachricht wiederholt.
-
-### Was bedeutet die Markierung – und was nicht?
-
-Die Berechnung ist eine geometrische Herleitung. Sie beweist nicht, dass Station A ihre Antenne tatsächlich auf Station B ausgerichtet hat. Ebenso wenig berücksichtigt sie Gelände, aktuelle Ausbreitungsbedingungen, die reale Antennencharakteristik der fremden Station oder deren Rotatorposition.
-
-ON4KST liefert keinen individuellen Öffnungswinkel für die fremde Station. KST4Contest verwendet deshalb den für die eigene Antenne konfigurierten Wert auch als Näherung für Station A. Ein zu großer Wert erzeugt entsprechend mehr mögliche Richtungsgelegenheiten, ein zu kleiner Wert kann brauchbare Situationen übersehen.
-
-Im Klartext: Die grüne Markierung ist ein begründeter Hinweis auf eine mögliche Gelegenheit. Sie ist weder eine Ausbreitungsvorhersage noch eine Garantie für ein QSO.

-## Weitergabe als DX-Cluster-Spot
+## Sked-Richtungs-Spots (Integrierter DX-Cluster)
 
-Seit Version 1.23 kann KST4Contest eine erkannte Richtungsgelegenheit an den DX-Cluster-Client eines Logprogramms weitergeben. Dafür muss der lokale DX-Cluster-Server aktiviert und für den Absender eine verwertbare Frequenz bekannt sein.
-
-Die Frequenz kann bereits aus einer früheren Nachricht stammen oder erstmals in der aktuell auslösenden Nachricht stehen. In beiden Fällen steht sie der Spot-Prüfung zur Verfügung. KST4Contest überträgt damit nicht jede im Chat gefundene QRG, sondern nur Frequenzen, die mit einer geometrisch passenden gerichteten Nachricht zusammenfallen.
-
-Die Fünf-Minuten-Markierung und der DX-Cluster-Spot beruhen auf derselben Richtungsberechnung, haben aber einen unterschiedlichen Lebenszyklus: Die Markierung bleibt vorübergehend in der Benutzerliste sichtbar. Der Spot wird unmittelbar beim Verarbeiten der passenden Nachricht erzeugt.
-
-Einrichtung, Frequenzbehandlung und Grenzen: [Integrierter DX-Cluster-Server](de-DX-Cluster-Server).
+Ab **v1.23**: Richtungs-Warnungen werden als DX-Cluster-Spots an das Logprogramm weitergeleitet, wenn eine QRG bekannt ist. Details: [DX-Cluster-Server](de-DX-Cluster-Server).
 
 ---
 
-## QRG-Erkennung
+## QRG-Erkennung (QRG Reading)
 
-Im ON4KST-Chat werden Frequenzen selten einheitlich geschrieben. Eine Station nennt beispielsweise zuerst `432.088`, später nur noch `.100` und in einer weiteren Nachricht `qrg 120`. Für einen Menschen ist der Zusammenhang meistens klar. Ein Programm muss dagegen unterscheiden, ob `120` eine Frequenz, eine Zeitangabe, eine Entfernung oder etwas völlig anderes bedeutet.
+KST4Contest verarbeitet jede Chat-Nachricht und extrahiert automatisch **Frequenzangaben**. Diese werden in der Benutzerliste in der **QRG-Spalte** angezeigt.
 
-KST4Contest wertet deshalb den Text jeder öffentlichen und gerichteten Chat-Nachricht aus. Eine erkannte QRG wird dem Absender zugeordnet und in der **QRG-Spalte** der Benutzerliste angezeigt. Die Spalte enthält die zuletzt erkannte Frequenz und stellt mindestens drei Nachkommastellen dar. Ein intern als `144.21` gespeicherter Wert erscheint damit als `144.210`.
+Erkannte Formate: `144.205`, `432.088`, `.205` (mit konfigurierter Bandannahme), etc.
 
-### Welche Angaben werden erkannt?
-
-| Schreibweise | Beispiel | Verarbeitung |
-|---|---|---|
-| Vollständige Frequenz | `144.210`, `432,088`, `10368.100` | Das Band ergibt sich direkt aus der Frequenz. |
-| Relative Frequenz mit Punkt oder Komma | `.210`, `,088` | Das Band wird aus dem Stationskontext oder dem konfigurierten Fallback ergänzt. |
-| Dreistellige Frequenz mit Textkontext | `qrg 210`, `freq is 210`, `on 210`, `210 MHz` | Die Zahl wird als relative Frequenz behandelt. |
-| Dreistellige Zahl ohne Frequenzkontext | `210`, `599`, `144` | Die Zahl wird absichtlich nicht als QRG übernommen. |
-
-Die letzte Einschränkung verhindert plausible, aber falsche Ergebnisse. Mit einem Fallback von `144 MHz` ließe sich ein Signalrapport `599` technisch problemlos zu `144.599 MHz` zusammensetzen. Das Ergebnis wäre formal gültig und fachlich trotzdem Unsinn.
-
-### Wie wird das Band einer relativen QRG bestimmt?
-
-KST4Contest verwendet folgende Reihenfolge:
-
-1. Wurde für denselben Absender innerhalb der letzten 30 Minuten bereits eine passende vollständige Frequenz erkannt, verwendet KST4Contest deren Band.
-2. Sind mehrere aktuelle Bänder bekannt, wird der zuletzt aktualisierte plausible Bandkontext verwendet.
-3. Fehlt ein geeigneter Stationskontext, verwendet KST4Contest das unter **Fallback band for relative QRG detection** ausgewählte Band.
-
-Beispiel: Das globale Fallback steht auf `144 MHz`. Eine Station nennt zunächst `432.088` und schreibt wenige Minuten später `.100`. KST4Contest ergänzt nicht das globale Fallback, sondern den aktuelleren Stationskontext. Das Ergebnis ist `432.100 MHz`. Schreibt eine andere Station ohne vorherige Bandinformation `.100`, wird daraus `144.100 MHz`.
-
-Das Fallback-Band ist damit tatsächlich nur der letzte Ausweg. Es wird aus den von KST4Contest unterstützten Bandwerten ausgewählt und wirkt auf die gesamte QRG-Erkennung – nicht nur auf den integrierten DX-Cluster.
-
-### Wofür wird die erkannte QRG verwendet?
-
-Die zuletzt erkannte Frequenz erscheint in der Benutzerliste. Der zugehörige Bandkontext kann außerdem in weitere Funktionen einfließen, beispielsweise in:
-
-- die Erkennung aktiver Bänder einer Station,
-- den Chatmember-Score und die Prioritätslisten,
-- Band-Upgrade-Hinweise nach einem Logeintrag,
-- die Frequenzwahl bei Skeds,
-- einen DX-Cluster-Spot aus einer erkannten Richtungsgelegenheit.
-
-Steht die QRG erstmals in der Nachricht, die zugleich eine Richtungsgelegenheit auslöst, wird sie vor der Richtungs- und Spotprüfung verarbeitet. Der daraus erzeugte Spot kann deshalb bereits die Frequenz dieser Nachricht verwenden.
-
-Die Erkennung bleibt eine Textauswertung. KST4Contest kann nicht beweisen, dass die Station noch auf der genannten Frequenz arbeitet oder ob sich eine mehrdeutige Angabe auf einen anderen Zusammenhang bezieht. Genau deshalb werden nackte dreistellige Zahlen ohne Frequenzkontext nicht mehr übernommen.
-
-Konfiguration und unterstützte Fallback-Bänder: [Fallback-Band für relative QRG-Erkennung](de-Konfiguration#fallback-band-für-relative-qrg-erkennung).
-
-Verwendung in der Bandmap eines Logprogramms: [Integrierter DX-Cluster-Server](de-DX-Cluster-Server).
+**Nutzen**: Ohne nachzufragen kann man direkt auf die QRG einer Station schauen und entscheiden, ob eine Verbindung möglich ist.

-## Gearbeitete Rufzeichen, neue Bänder und neue Großfelder
 
-KST4Contest unterscheidet drei Informationen, die im Contest ähnlich aussehen können, aber unterschiedliche Fragen beantworten:
+## Worked-Markierung
 
-1. Wurde dieses Rufzeichen bereits gearbeitet?
-2. Wurde dieses Rufzeichen auf einem bestimmten Band gearbeitet?
-3. Wurde das vierstellige Maidenhead-Großfeld bereits gearbeitet – möglicherweise mit einer anderen Station?
-
-Diese Trennung ist notwendig. Ein bereits gearbeitetes Rufzeichen kann auf einem anderen Band weiterhin interessant sein. Umgekehrt kann eine noch nicht gearbeitete Station in einem Großfeld liegen, das bereits im Log steht.
-
-### Worked-Informationen aus dem Log
-
-Die [Log-Synchronisation](de-Log-Synchronisation) übernimmt neue QSOs aus dem Logprogramm. Welche Informationen dabei zur Verfügung stehen, hängt von der verwendeten Schnittstelle ab:
-
-- Der dateibasierte Simplelogfile-Interpreter erkennt nur das Rufzeichen. Er kann deshalb lediglich den globalen Worked-Status setzen.
-- Die QSO-UDP-Schnittstellen und der Win-Test-Netzwerk-Listener können zusätzlich das Band übernehmen.
-- Enthält das Logpaket einen gültigen Locator, speichert KST4Contest außerdem das gearbeitete vierstellige Großfeld für dieses Band.
-
-Fehlt eine Information im Logpaket, wird sie nicht geraten. Ein QSO ohne Locator erzeugt deshalb keinen Großfeld-Eintrag; ein Simplelogfile-Treffer erzeugt keine bandbezogene Worked-Markierung.
-
-### Bedeutung der Bandspalten
-
-Unter der gemeinsamen Spalte **worked** erscheinen nur die Bänder, die unter **Station → my station uses …** aktiviert wurden. Die Zellen verwenden bewusst kurze Kennzeichen:
-
-| Anzeige | Bedeutung |
-|---|---|
-| `X` | Das Rufzeichen wurde auf diesem Band gearbeitet. |
-| `a` | Die Station bietet dieses Band an, das Band ist noch nicht gearbeitet und das Rufzeichen wurde bisher auf keinem Band gearbeitet. |
-| `B+` | Die Station bietet dieses Band an und das Band ist noch nicht gearbeitet. Das Rufzeichen wurde bereits auf einem anderen Band gearbeitet. Ist die getrennte `a`-Anzeige deaktiviert, wird auch ein vollständig neues Rufzeichen als `B+` dargestellt. |
-| `o` | Das vierstellige Großfeld der Station wurde auf diesem Band bereits gearbeitet – unabhängig vom Rufzeichen. |
-| leer | Für dieses Band liegt keine passende Information vor. Das ist nicht gleichbedeutend mit „nicht QRV“. |
-
-Das `o` ist eine unabhängige Zusatzinformation und kann deshalb mit den anderen Kennzeichen kombiniert werden. Möglich sind beispielsweise `Xo`, `ao` oder `B+o`. Ein einzelnes `o` bedeutet: Das Großfeld wurde auf diesem Band bereits gearbeitet, für das angezeigte Rufzeichen liegt aber weder eine Worked-Markierung noch eine aktuelle Bandmöglichkeit vor.
-
-![Bandbezogener Worked-Status und Worked-Großfelder](worked_band_status.png)
-
-### Wie entsteht eine Bandmöglichkeit?
-
-KST4Contest zeigt `a` oder `B+` nur an, wenn sich eine noch offene gemeinsame Bandmöglichkeit herleiten lässt. Dafür werden folgende Informationen zusammengeführt:
-
-1. die in den Stationseinstellungen aktivierten eigenen Bänder,
-2. höchstens 30 Minuten alte QRG-Erkennungen der Gegenstation,
-3. eindeutige Bandangaben im Namensfeld der Gegenstation,
-4. die pro Band gespeicherten Worked-Markierungen und
-5. manuell gesetzte NOT-QRV-Markierungen.
-
-Aktive Chat-Einträge mit demselben normalisierten Rufzeichen werden gemeinsam ausgewertet. Das ist insbesondere bei mehreren Chat-Kategorien oder unterschiedlichen sichtbaren Rufzeichenvarianten wichtig. Eine eindeutige Bandangabe im Namensfeld bleibt dabei so lange nutzbar, wie der betreffende Chat-Eintrag aktiv ist; eine aus einer Nachricht erkannte QRG läuft nach 30 Minuten aus.
-
-Anschließend werden nur die Bänder berücksichtigt, die an der eigenen Station aktiviert, für die Gegenstation bekannt und noch nicht gearbeitet sind. Ein manuelles NOT-QRV-Tag übersteuert die automatisch erkannten Hinweise. Die Chat-Kategorie allein reicht dagegen nicht als Nachweis, dass eine einzelne Station auf einem bestimmten Band QRV ist.
-
-Die globale Worked-Markierung entscheidet nicht darüber, ob eine Bandmöglichkeit besteht. Sie unterscheidet in der Darstellung lediglich zwischen `a` und `B+`. Die eigentliche Bandprüfung arbeitet mit den bandbezogenen Worked-Informationen.
-
-### Bedeutung von `wkdany`
-
-Die Unterspalte **wkdany** fasst den globalen Rufzeichen- und Großfeldstatus zusammen:
-
-| Anzeige | Bedeutung |
-|---|---|
-| leer | Weder das Rufzeichen noch das vierstellige Großfeld wurden gearbeitet. |
-| `x` | Das Rufzeichen wurde auf mindestens einem Band gearbeitet. |
-| `o` | Das vierstellige Großfeld wurde auf mindestens einem Band gearbeitet. |
-| `xo` | Rufzeichen und Großfeld wurden bereits gearbeitet. |
-
-`wkdany` ist eine bandunabhängige Übersicht. Das kleine `x` darf daher nicht mit dem großen `X` in einer Bandspalte verwechselt werden. Der globale Status wird für die Anzeige und den globalen **wkd**-Filter verwendet, nicht als Ersatz für bandbezogene Worked-Informationen.
-
-### NOT-QRV-Markierungen
-
-Teilt eine Station mit, dass sie auf einem bestimmten Band nicht QRV ist, kann dies im **Further Info**-Bereich der ausgewählten Station markiert werden:
-
-1. Station in der Benutzerliste auswählen.
-2. Im Bereich **Not QRV** das betreffende Band aktivieren.
-3. **tag not qrv all** nur verwenden, wenn die Station auf keinem der unterstützten Bänder angefragt werden soll.
-
-Angezeigt werden die einzelnen NOT-QRV-Schalter der Bänder, die für die eigene Station aktiviert sind. **tag not qrv all** setzt dagegen alle unterstützten Bänder, auch wenn einzelne davon momentan nicht in der Benutzeroberfläche eingeblendet sind. Die Markierung wird bandbezogen unter dem normalisierten Rufzeichen gespeichert und auf dessen aktive Chat-Varianten übertragen.
-
-![Bandbezogene NOT-QRV-Markierungen im Further-Info-Bereich](not_qrv_controls.png)
-
-NOT-QRV ist eine manuelle Korrektur und hat deshalb Vorrang vor automatisch erkannten QRGs und Bandangaben im Namensfeld. Das betreffende Band wird nicht mehr als `a` oder `B+` angeboten, vom **New bands**-Filter nicht als Gelegenheit gewertet und von den zugehörigen Bandfiltern ausgeblendet.
-
-Im Klartext: Ein erkannter Hinweis bedeutet „wahrscheinlich auf diesem Band aktiv“. Ein manuelles NOT-QRV-Tag bedeutet „für unsere weitere Auswahl nicht auf diesem Band anfragen“. Diese Entscheidung soll nicht durch die nächste erkannte Zahl wieder aufgehoben werden.
-
-### Speicherung und Lebensdauer
-
-Worked-, NOT-QRV- und Großfeldinformationen werden in der internen SQLite-Datenbank gespeichert und beim nächsten Start wieder geladen. Die Einträge laufen nach drei Tagen automatisch ab. Ein Reset vor jedem Contest ist deshalb normalerweise nicht erforderlich.
-
-Ein manueller Reset unter **Workedstn database** entfernt sämtliche Worked-Markierungen, NOT-QRV-Tags und gespeicherten Worked-Großfelder. Die bekannten Rufzeichenzeilen bleiben dabei in der Datenbank erhalten. Einzelheiten: [Worked Station Database Settings](de-Konfiguration#worked-station-database-settings-gearbeitete-stationen-datenbank).

-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.
+**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.
 
-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.

+- **Worked-Markierung**: Bereits gearbeitete Stationen werden farblich markiert, direkt aus dem Logprogramm via UDP synchronisiert.
+- **Sked-Richtungs-Erkennung**: Wenn eine Station eine andere aus deiner Richtung anruft, wird sie grün und fett hervorgehoben.
+- **QRG-Erkennung**: KST4Contest liest Frequenzen automatisch aus dem Chat-Verkehr und zeigt sie in der Benutzerliste an.
+- **AirScout-Interface**: Anzeige reflektierbarer Flugzeuge direkt in der Benutzerliste.
+- **Integrierter DX-Cluster-Server**: Spots werden direkt an das Logprogramm gesendet.
+- **Dark Mode** (ab v1.26): Schont die Augen in der Nacht.
+- **Multi-Channel-Login** (ab v1.26): Gleichzeitig in zwei Chat-Kategorien einloggen.
 
-Ein Fehler lässt sich wesentlich schneller nachvollziehen, wenn die Meldung mindestens folgende Angaben enthält:
+---
 
-1. verwendete KST4Contest-Version,
-2. Betriebssystem und Installationsart,
-3. genaue Schritte bis zum Fehler,
-4. erwartetes und tatsächlich beobachtetes Verhalten,
-5. gegebenenfalls einen Screenshot,
-6. die Fehler-Logdatei.
+## Kontakt & Support
 
-Die Fehler-Logdatei wird hier gespeichert:
-
-| Betriebssystem | Pfad |
-|---|---|
-| Linux / macOS | `~/.praktiKST/kst4contest-errors.log` |
-| Windows | `C:\Users\<Benutzername>\.praktiKST\kst4contest-errors.log` |
-
-Vor dem Hochladen sollte die Datei kurz geprüft werden. Ein Fehlerprotokoll enthält überwiegend technische Informationen, kann abhängig vom Fehler aber beispielsweise lokale Dateipfade oder weitere Kontextdaten enthalten.
-
-In Datei- und Verzeichnisnamen wird teilweise noch der technische Name `praktiKST` verwendet. Gemeint ist dasselbe Programm.

-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.
-
-Benötigt werden damit im Wesentlichen ein unterstütztes Betriebssystem, eine Internetverbindung und ein ON4KST-Account. Das klingt zunächst überschaubar – und ist es normalerweise auch.
-
 ## Voraussetzungen
 
+Es wird eine Mindestauflösung von 1200px mal 720px empfohlen
+
 ### ON4KST-Account
 
-KST4Contest ist ein eigenständiger Client für den ON4KST-Chat, ersetzt aber nicht den dazugehörigen Benutzeraccount.
+Um den Chat zu nutzen, ist ein registrierter Account beim ON4KST-Chat-Dienst erforderlich:
 
-Falls noch kein Account vorhanden ist, kann er über die offizielle ON4KST-Seite angelegt werden:
+- Registrierung unter: http://www.on4kst.info/chat/register.php
 
-- [ON4KST-Anmeldung und Registrierung](https://www.on4kst.org/chat/login.php)
+### Verhaltensregeln im Chat
 
-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.
+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.
 
-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.
+### Persönliche Nachrichten
 
-### Bildschirmgröße
+Um eine Privatnachricht an eine andere Station zu senden, immer folgendes Format verwenden:
 
-Eine nutzbare Bildschirmfläche von ungefähr **1200 × 720 Pixeln** oder mehr wird empfohlen.
+```
+/CQ RUFZEICHEN Nachrichtentext
+```
 
-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.
+Beispiel: `/CQ DL5ASG pse sked 144.205?`
 
-### 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.
+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)).

-## Installation unter Windows
+## Installation
 
-KST4Contest wird unter Windows als ZIP-Paket bereitgestellt. Ein klassischer Installer ist nicht erforderlich.
+### Windows
 
-1. Lade `praktiKST-v<Version>-windows-x64.zip` aus dem aktuellen Release herunter.
-2. Entpacke die ZIP-Datei vollständig in einen eigenen Ordner.
-3. Öffne den entpackten Ordner.
-4. Starte `praktiKST.exe`.
+1. ZIP-Datei herunterladen.
+2. ZIP-Datei in einen gewünschten Ordner entpacken.
+3. `praktiKST.exe` ausführen.
 
-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.
+Die Einstellungen werden unter `%USERPROFILE%\.praktikst\preferences.xml` gespeichert.
 
-Die Programmeinstellungen befinden sich nicht im entpackten Programmordner, sondern im Benutzerverzeichnis:
+### Linux
+1. AppImage herunterladen.
+2. AppImage in gewünschten Ordner entpacken.
+3. AppImage ausführbar machen (geht im Terminal mit `chmod +x KST4Contest-v<Versionsnummer>-linux-x86_64.AppImage`)
+4. AppImage ausführen.
 
-```text
-%USERPROFILE%\.praktiKST\preferences.xml
-```
+Die Einstellungen werden unter `~/.praktikst/preferences.xml` gespeichert.
 
-Dadurch können neue Programmversionen in einen anderen Ordner entpackt werden, ohne dass die vorhandenen Einstellungen verloren gehen.
+### 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.
+
+Die Einstellungen werden unter `~/.praktikst/preferences.xml` gespeichert.

-## Installation unter Linux
+## Update
 
-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.
+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.
 
-| 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 |
+![Beispiel Update Fenster](update_window.png)
 
-### Flatpak
+### Update-Prozess
 
-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.
+#### Windows
 
-#### Stable über die Release-Datei installieren
+Derzeit gibt es nur einen Weg zum Aktualisieren:
 
-Lade `de.x08.KST4Contest.flatpakref` aus dem aktuellen Release herunter und öffne die Datei mit der Softwareverwaltung der verwendeten Desktop-Umgebung.
+1. Den alten Ordner löschen.
+2. Das neue ZIP entpacken.
 
-Alternativ kann sie im Terminal installiert werden:
+Die Einstellungsdatei (`preferences.xml`) bleibt erhalten, da sie im Benutzerordner gespeichert ist – nicht im Programmordner.
 
-```bash
-flatpak install ./de.x08.KST4Contest.flatpakref
-```
+#### Linux
 
-#### KST4Contest-Repository hinzufügen
+Derzeit folgendermaßen:
+1. neues AppImage herunterladen
+2. neues AppImage ausführbar makieren
+3. (optional) altes AppImage löschen.
 
-Das Repository muss nur einmal hinzugefügt werden:
+#### macOS
 
-```bash
-flatpak remote-add --if-not-exists kst4contest \
-https://praktimarc.github.io/kst4contest/kst4contest.flatpakrepo
-```
+1. Neue DMG-Datei herunterladen.
+2. DMG öffnen.
+3. Die neue `KST4Contest.app` in den **Programme**-Ordner ziehen und die alte Version ersetzen.
 
-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
-```
-
-Alternativ kann die Datei in einer grafischen Paketverwaltung geöffnet werden.
-
-### Fedora und kompatible RPM-Systeme
-
-Installiere das RPM-Paket mit:
-
-```bash
-sudo dnf install ./KST4Contest-v<Version>-fedora-x86_64.rpm
-```
-
-### 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
-```
-
-### 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:
-
-```bash
-yay -S kst4contest-bin
-```
-
-Stable aus dem Quellcode bauen:
-
-```bash
-yay -S kst4contest
-```
-
-Aktuellen Entwicklungsstand bauen:
-
-```bash
-yay -S kst4contest-git
-```
-
-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
+## Bekannte Probleme beim Start
 
-> **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.
+### Norton 360
 
-Für Apple-Silicon-Macs wird das Paket mit `arm64` benötigt. Für Intel-Macs ist das Paket mit `x86_64` vorgesehen.
+Norton 360 stuft `praktiKST.exe` als gefährlich ein (Fehlalarm). Es muss eine Ausnahme für die Datei eingerichtet werden:
 
-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.
+1. Norton 360 öffnen.
+2. Sicherheit → Verlauf → Das entsprechende Ereignis suchen.
+3. „Wiederherstellen & Ausnahme hinzufügen" wählen.
 
-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 |
-|---|---|---|
-| Windows | `%USERPROFILE%\.praktiKST\` | `%USERPROFILE%\.praktiKST\preferences.xml` |
-| Linux | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
-| macOS | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
-
-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
-sudo apt install ./KST4Contest-v<Version>-debian-amd64.deb
-```
-
-### Fedora aktualisieren
-
-```bash
-sudo dnf upgrade ./KST4Contest-v<Version>-fedora-x86_64.rpm
-```
-
-### Arch-Paket aktualisieren
-
-```bash
-sudo pacman -U KST4Contest-v<Version>-archlinux-x86_64.pkg.tar.zst
-```
-
-### 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.

-
-## Probleme beim ersten Start
-
-### Windows meldet eine unbekannte Anwendung
-
-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.
-
-Prüfe in diesem Fall zuerst:
-
-- 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?
-
-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.
-
-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 KST4Contest-Version,
-- den vollständigen Dateinamen,
-- das verwendete Sicherheitsprodukt und dessen Version,
-- den angezeigten Erkennungsnamen,
-- möglichst einen Screenshot der Meldung.
-
-### Das AppImage startet nicht
-
-Prüfe zuerst das Ausführungsrecht:
-
-```bash
-chmod +x KST4Contest-v<Version>-linux-x86_64.AppImage
-```
-
-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.
-
-### Das Problem bleibt bestehen
-
-Prüfe zunächst, ob das Problem bereits unter [GitHub Issues](https://github.com/praktimarc/kst4contest/issues) beschrieben wurde. Falls nicht, erstelle einen neuen Issue mit:
-
-- Betriebssystem und Version,
-- verwendeter KST4Contest-Version,
-- Installationsart,
-- genauer Fehlermeldung,
-- den Schritten, mit denen sich das Problem reproduzieren lässt.
-
-„Geht nicht“ beschreibt den Zustand meistens korrekt, hilft bei der Fehlersuche aber nur begrenzt.

+Einen realistischen Wert für den Öffnungswinkel der eigenen Antenne eintragen (in Grad). Dieser Wert wird für die [Sked-Richtungs-Hervorhebung](Funktionen#sked-richtungs-hervorhebung) verwendet. Ein Testwert von 50° hat sich bewährt; DM5M nutzt Quads mit 69°.
 
-Der Wert wird an mehreren Stellen verwendet:
-
-- für den QTF-Filter der Benutzerliste,
-- für die Darstellung des eigenen Antennenkorridors,
-- als angenommener Öffnungswinkel einer fremden Station bei der [Herleitung von Richtungsgelegenheiten](de-Funktionen#richtungsgelegenheiten-aus-gerichteten-nachrichten).
-
-Der letzte Punkt ist bewusst eine Näherung. ON4KST überträgt weder die verwendete Antenne noch deren Öffnungswinkel. KST4Contest verwendet deshalb den eigenen Wert als praktikable Annahme für die Gegenstation.
-
-Wähle einen realistischen Wert. Ein zu großer Öffnungswinkel erzeugt viele geometrische Treffer, die praktisch kaum noch eine Aussage haben. Ein zu kleiner Wert kann dagegen brauchbare Richtungsgelegenheiten ausblenden.
+> **Keinesfalls** Fantasy-Werte eintragen – die Richtungsberechnungen werden sonst unbrauchbar.
 
 ### Standard-Maximum-QRB
 
-Trage die maximale Entfernung in Kilometern ein, innerhalb der KST4Contest Richtungsgelegenheiten berücksichtigen soll. Maßgeblich ist die Entfernung zwischen der eigenen Station und dem Absender der gerichteten Nachricht – nicht die Entfernung zwischen Absender und Empfänger.
-
-Liegt der Absender weiter entfernt, wird die Situation auch dann nicht hervorgehoben und nicht als Richtungsgelegenheit an den lokalen DX-Cluster-Server weitergegeben, wenn der berechnete Winkel passen würde.
-
-Der Wert sollte zum eigenen Stationsaufbau und zum vorgesehenen Contestbetrieb passen. Ein unnötig großer Bereich erzeugt Hinweise für Stationen, die praktisch nicht mehr zum Arbeitsbereich gehören; ein zu kleiner Bereich blendet mögliche Kandidaten bereits vor der Richtungsbewertung aus.
+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.

 ## Notification Settings (Benachrichtigungen)
 
-![Benachrichtigungen, DX-Cluster-Ausgabe und QSO-Monitoring](client_settings_window_notification.png)
+Drei Benachrichtigungstypen stehen zur Wahl:
 
-Im Reiter **Notification** werden nicht nur akustische Hinweise konfiguriert. Hier befinden sich auch die Einstellungen für den lokalen DX-Cluster-Server, den Band-Upgrade-Hinweis und das QSO-Monitoring.
-
-### Akustische Hinweise
-
-Die drei Audiofunktionen arbeiten unabhängig voneinander:
-
-- **Play notification sounds …** aktiviert kurze Hinweistöne für neue Privatnachrichten, erkannte Richtungsgelegenheiten, Sked-Erinnerungen und Band-Upgrade-Hinweise.
-- **Spell the sender's callsign in CW …** gibt das Rufzeichen des Absenders einer neuen Privatnachricht als CW-Signal aus.
-- **Speak the sender's callsign phonetically …** spricht das Rufzeichen des Absenders phonetisch aus.
-
-CW- und Sprachausgabe können gleichzeitig aktiviert werden. Das ist technisch möglich, im Contest aber nicht zwingend hilfreich. In der Praxis sollte nur die Ausgabe eingeschaltet werden, die im eigenen Stationsbetrieb tatsächlich wahrgenommen werden kann, ohne den Operator dauerhaft zu beschäftigen.
-
-### Fallback-Band für relative QRG-Erkennung
-
-Das Dropdown **Fallback band for relative QRG detection** legt fest, welches Band KST4Contest verwendet, wenn eine relative QRG keinem aktuellen Stationskontext zugeordnet werden kann.
-
-Zur Auswahl stehen ausschließlich die vom Frequenzparser unterstützten Bandpräfixe:
-
-```text
-50 MHz
-70 MHz
-144 MHz
-432 MHz
-1296 MHz
-2320 MHz
-3400 MHz
-5760 MHz
-10368 MHz (10G)
-24048 MHz (24G)
-```
-
-Das Dropdown ist kein Filter und keine Vorgabe für vollständig angegebene Frequenzen. `432.088` wird unabhängig von der Auswahl als Frequenz im 432-MHz-Band erkannt. Benötigt wird das Fallback bei relativen Angaben wie `.205`, `,205` oder `qrg 205`.
-
-Bevor KST4Contest auf das Fallback zurückgreift, prüft es den Bandkontext des Absenders. Wurde für dieselbe Station innerhalb der letzten 30 Minuten bereits eine passende vollständige Frequenz erkannt, hat dieses Band Vorrang. Ein Fallback von `144 MHz` macht aus `.100` daher `432.100 MHz`, wenn die Station kurz zuvor beispielsweise `432.088` genannt hat.
-
-Die Einstellung befindet sich im Notification-Bereich, wirkt aber auf die gesamte QRG-Erkennung. Damit beeinflusst sie nicht nur mögliche DX-Cluster-Spots, sondern auch die QRG-Spalte, erkannte aktive Bänder, Priorisierung, Band-Upgrade-Hinweise und Funktionen, die eine bekannte Stationsfrequenz verwenden.
-
-Mehr zur Erkennungslogik und zu absichtlich ignorierten Zahlen: [QRG-Erkennung](de-Funktionen#qrg-erkennung).
-
-### Local DX Cluster output
-
-KST4Contest kann erkannte Richtungsgelegenheiten als DX-Cluster-Spots an ein Logprogramm weitergeben. Eine im Chat erkannte Frequenz erscheint dadurch direkt in der Bandmap des Logprogramms und muss nicht erst von Hand übertragen werden.
-
-Die Checkbox **Enable the local DX Cluster server …** startet beziehungsweise beendet den lokalen TCP-Server. Bei einer laufenden Chat-Verbindung wird die Änderung sofort wirksam.
-
-Folgende Einstellungen und Schaltflächen gehören zur lokalen DX-Cluster-Ausgabe:
-
-- **TCP port**: Port, auf dem KST4Contest Verbindungen von DX-Cluster-Clients annimmt. Der Standardwert ist `8000`. Wird der Port während einer laufenden Verbindung geändert, startet KST4Contest den Server auf dem neuen Port neu. Der Logger muss sich anschließend ebenfalls mit dem neuen Port verbinden.
-- **Fallback band for relative QRG detection**: Das oben beschriebene globale Fallback-Band. Der Testspot verwendet `.300` dieses Bandes. Reale Spots verwenden dagegen die für den jeweiligen Absender erkannte QRG.
-- **Spotter callsign**: Rufzeichen, das im erzeugten DX-Cluster-Spot als Spotter erscheint. Hier sollte ein anderes Rufzeichen als das im Contest verwendete Stationsrufzeichen eingetragen werden. Einige Logprogramme filtern Spots des eigenen Rufzeichens oder behandeln sie anders als fremde Spots.
-- **Send test spot**: Sendet einen Testspot für `DL0TEST` auf `.300` des ausgewählten Fallback-Bandes. Der Test funktioniert nur, wenn KST4Contest mit dem Chat verbunden, der lokale DX-Cluster-Server aktiviert und mindestens ein DX-Cluster-Client verbunden ist.
-
-KST4Contest erzeugt nicht bei jeder im Chat gefundenen Frequenz automatisch einen Spot. Ein Spot entsteht nur dann, wenn eine gerichtete Nachricht zwischen zwei Stationen auf eine für die eigene Station interessante Antennenrichtung schließen lässt und für den Absender eine nutzbare Frequenz bekannt ist.
-
-Die vollständige Herleitung und die Einrichtung des Logprogramms sind im Kapitel [Integrierter DX-Cluster-Server](de-DX-Cluster-Server) beschrieben.
-### Band-Upgrade-Hinweis nach einem Logeintrag
-
-Nach einem über UCXLog oder Win-Test empfangenen Logeintrag kann KST4Contest prüfen, ob die gerade gearbeitete Station noch ein weiteres gemeinsames, aber bisher nicht gearbeitetes Band anbietet.
-
-Die Prüfung verwendet dieselbe Bandherleitung wie die `a`- und `B+`-Anzeige:
-
-1. die in den Stationseinstellungen aktivierten eigenen Bänder,
-2. höchstens 30 Minuten alte QRG-Erkennungen der Gegenstation,
-3. eindeutige Bandangaben im Namensfeld ihrer aktiven Chat-Einträge,
-4. die pro Band gespeicherten Worked-Markierungen und
-5. manuell gesetzte NOT-QRV-Tags.
-
-Aktive Chat-Varianten desselben normalisierten Rufzeichens werden gemeinsam ausgewertet. NOT-QRV hat Vorrang vor einer automatisch erkannten QRG oder Bandangabe.
-
-Bleibt mindestens ein gemeinsames, noch nicht gearbeitetes Band übrig, erscheint im Hauptfenster für ungefähr zwölf Sekunden ein blinkender **BAND+**-Hinweis mit Rufzeichen und den noch offenen Bändern. Der Tooltip zeigt die vollständige Herleitung. Ist die allgemeine Soundausgabe aktiviert, wird zusätzlich ein kurzer Hinweiston abgespielt.
-
-Die beiden Optionen haben unterschiedliche Aufgaben:
-
-- **Blink + sound …** aktiviert den Hinweis nach einem passenden Logeintrag.
-- **Priority boost …** erhöht zusätzlich die Priorität von Stationen mit einer offenen Bandmöglichkeit. Der Boost ist ein Faktor innerhalb der gesamten Prioritätsberechnung und garantiert keinen bestimmten Listenplatz.
-
-Der Hinweis setzt eine Log-Synchronisation mit Bandinformation voraus. Der einfache dateibasierte Callsign-Interpreter erkennt lediglich Rufzeichen und liefert deshalb keine sichere Information über das Band des gerade geloggten QSOs.
-
-Weitere Hintergründe: [Band-Upgrade-Hinweis nach einem Logeintrag](de-Funktionen#band-upgrade-hinweis-nach-einem-logeintrag).
-
-### Sniffer-Einstellungen (ab v1.31)
-
-Das QSO-Monitoring ist für Stationen gedacht, deren Kommunikation man gezielt verfolgen möchte. Das kann beispielsweise eine seltene Station, eine DXpedition oder eine andere Station des eigenen Contest-Teams sein.
-
-Für jedes eingetragene Rufzeichen zeigt KST4Contest Nachrichten zusätzlich in der PM-Tabelle an, wenn das Rufzeichen entweder Absender oder Empfänger der Nachricht ist. Die ursprüngliche Nachricht wird dabei nicht aus ihrer normalen Tabelle entfernt.
-
-Überwachte Nachrichten werden in der PM-Tabelle eindeutig gekennzeichnet:
-
-```text
-Sniffed: (SENDER > RECEIVER) Nachrichtentext
-```
-
-So wird sichtbar, dass die Nachricht nicht an die eigene Station gerichtet war.
-
-Rufzeichen werden folgendermaßen verwaltet:
-
-1. Mit **Add monitored callsign** ein neues Rufzeichen hinzufügen.
-2. Ein vorhandenes Rufzeichen per Doppelklick bearbeiten und die Änderung mit `Enter` übernehmen.
-3. Zum Entfernen den Inhalt einer Tabellenzelle löschen und mit `Enter` bestätigen.
-
-Doppelte oder syntaktisch ungültige Rufzeichen werden nicht übernommen. Die Liste wird mit **Save Settings** in der `preferences.xml` gespeichert und beim nächsten Programmstart wiederhergestellt.
+1. **Einfache Sounds**: TADA-Sound für eingehende Nachrichten, Tick für Sked-Richtungserkennung usw.
+2. **CW-Ansage**: Das Rufzeichen einer Station, die eine Privatnachricht sendet, wird als CW-Signal ausgegeben.
+3. **Phonetische Ansage**: Das Rufzeichen wird phonetisch ausgesprochen.

 ## Beacon Settings (Automatischer Beacon)
 
-![Beacon-Einstellungen](client_settings_window_beacon.png)
+Konfiguration eines automatischen Intervall-Beacons im öffentlichen Chat-Kanal. Empfohlen: Variable `MYQRG` im Text verwenden, damit die aktuelle Frequenz immer aktuell ist. Intervall und Text sind frei konfigurierbar.
 
-Ein Beacon sendet in regelmäßigen Abständen eine öffentliche CQ-Nachricht. Er ist für Betriebssituationen gedacht, in denen die eigene Station über längere Zeit auf einer festen Frequenz ruft. Andere Stationen erhalten dadurch eine aktuelle QRG-Information, ohne dass der Operator denselben Text wiederholt von Hand in den Chat schreiben muss.
+> **Tipp**: Beacon beim CQ-Rufen aktivieren und im Einstellungsfenster schnell deaktivieren, wenn kein CQ gerufen wird.
 
-KST4Contest verwendet einen gemeinsamen Timer für beide Chat-Kategorien. Aktivierung und Nachrichtentext werden trotzdem getrennt konfiguriert:
-
-- **Enable CQ beacon** aktiviert den Beacon der betreffenden Kategorie.
-- **Beacon message** enthält den öffentlichen Nachrichtentext dieser Kategorie.
-- **Shared beacon interval** legt das gemeinsame Intervall für beide Kategorien fest.
-
-Sind beide Beacons aktiviert, werden sie beim selben Timer-Lauf nacheinander in ihren jeweiligen Kategorien gesendet. Der zweite Beacon wird nur berücksichtigt, wenn auch der zweite Chat aktiviert und verbunden ist.
-
-### Intervall und Timer-Verhalten
-
-Das Intervall wird in ganzen Minuten angegeben. Der kleinste zulässige Wert ist eine Minute.
-
-Nach dem Aufbau der Chat-Verbindung prüft KST4Contest die Beacons erstmals nach ungefähr zehn Sekunden. Anschließend gilt das eingestellte Intervall. Wird der Wert während einer laufenden Verbindung geändert, beginnt der Countdown mit dem neuen Intervall erneut. Die Änderung selbst löst keine sofortige Nachricht aus.
-
-### Nachrichtentext und Variablen
-
-Ein Beacon darf nach der Variablenauflösung höchstens 120 Zeichen enthalten. KST4Contest prüft deshalb nicht nur das eingetragene Template, sondern den tatsächlich zu sendenden Text.
-
-Im Beacon können alle [globalen Variablen](de-Makros-und-Variablen#variablen-im-beacon) verwendet werden, beispielsweise:
-
-```text
-calling cq at MYQRG, ant MYQTF deg, loc MYLOCATOR
-```
-
-Die Variablen werden bei jedem Timer-Lauf neu aufgelöst. Ändert die Logsoftware zwischenzeitlich die in `MYQRG` gespeicherte Frequenz, verwendet bereits der nächste Beacon den neuen Wert.
-
-Stationsbezogene Variablen wie `QRZNAME`, `FIRSTAP` oder `SECONDAP` benötigen dagegen eine ausgewählte Gegenstation. Da ein öffentlicher Beacon keine Gegenstation adressiert, werden diese Variablen im Beacon nicht aufgelöst.
-
-### Wann sollte der Beacon ausgeschaltet werden?
-
-Der Beacon ist nur dann hilfreich, wenn seine QRG-Angabe zum tatsächlichen Betrieb passt. Bleibt er beim Absuchen oder häufigen Wechseln von Frequenzen aktiviert, können andere Stationen auf einer inzwischen falschen Frequenz nach der eigenen Station suchen.
-
-Im Klartext: Solange auf einer festen QRG CQ gerufen wird, spart der Beacon Arbeit. Beim „Schleichen“ über das Band sollte er ausgeschaltet werden.
-
-Änderungen wirken während der laufenden Verbindung. Damit Aktivierung, Texte und Intervall auch nach dem nächsten Programmstart erhalten bleiben, anschließend **Save Settings** verwenden.

 ## Messagehandling Settings (ab v1.25)
 
-![Automatische Antworten](client_settings_window_messagehandling.png)
+Neuer Einstellungsbereich mit folgenden Optionen:
 
-Die wichtigste Anwendung der allgemeinen automatischen Antwort betrifft Stationen, die zwar im ON4KST-Chat eingeloggt sind, den laufenden Contest aber nicht mitfunken. Gerade während größerer Contests werden Sked-Anfragen teilweise unkoordiniert und in großer Zahl an eingeloggte Stationen verteilt, ohne vorher zu prüfen, ob sie überhaupt teilnehmen. Die Empfänger müssten sonst immer wieder dieselbe Absage schreiben.
-
-KST4Contest kann darauf mit einem vorher festgelegten Text reagieren. Davon getrennt steht eine gezielte QRG-Auskunft zur Verfügung. Beide Funktionen können unabhängig voneinander aktiviert werden.
-
-### Allgemeine automatische Antwort
-
-**Enable automatic reply to all private messages** beantwortet eingehende Privatnachrichten mit dem Text im Feld rechts daneben. Es gibt einen gemeinsamen Text für beide Chat-Kategorien. Die beim Eingeben verwendete Groß- und Kleinschreibung bleibt erhalten.
-
-Eine zweckmäßige Nachricht ist beispielsweise:
-
-```text
-Sri, I am not taking part in this contest. No skeds.
-```
-
-Die eingegangene Privatnachricht bleibt sichtbar. Die Funktion blockiert oder verwirft keine Anfrage, sondern erspart lediglich die wiederholte manuelle Antwort.
-
-Die Antwort wird in derselben Chat-Kategorie gesendet, in der die Privatnachricht eingegangen ist. Das ist bei einem parallelen Login in zwei Kategorien entscheidend: Eine Nachricht aus dem Microwave-Chat darf nicht versehentlich im VHF/UHF-Chat beantwortet werden.
-
-### Automatische QRG-Antwort
-
-**Enable automatic QRG replies** reagiert auf typische QRG-Anfragen. Die Erkennung unterscheidet nicht zwischen Groß- und Kleinschreibung und sucht nach folgenden Textbestandteilen:
-
-```text
-ur qrg?
-your qrg?
-qrg?
-freq?
-pse qrg
-```
-
-Die Antwort enthält nur die QRG der Kategorie, in der die Anfrage eingegangen ist:
-
-| Eingegangene Privatnachricht | Verwendete QRG |
-|---|---|
-| Hauptkategorie | aktuelle QRG der Hauptkategorie |
-| zweite Chat-Kategorie | aktuelle QRG der zweiten Kategorie |
-
-Die Werte stammen aus denselben QRG-Feldern, die auch von `MYQRG` und `SECONDQRG` verwendet werden. Die Haupt-QRG kann manuell eingetragen oder durch die [TRX-Synchronisation](#trx-sync-einstellungen) aktualisiert werden. Für die zweite Kategorie wird der dort konfigurierte beziehungsweise manuell eingetragene Wert verwendet.
-
-Sind die allgemeine und die QRG-bezogene Antwort gleichzeitig aktiviert, hat die QRG-Antwort Vorrang. Eine erkannte QRG-Anfrage erzeugt daher nicht zusätzlich den allgemeinen Antworttext.
-
-### Schutz vor wiederholten Antworten
-
-Jede automatisch erzeugte Nachricht trägt das feste Präfix:
-
-```text
-[KST4C Automsg]
-```
-
-Die allgemeine und die QRG-bezogene Antwort reagieren nicht auf Nachrichten, die dieses Präfix bereits enthalten. Dadurch beantworten sich zwei entsprechend arbeitende Clients nicht gegenseitig in einer Schleife.
-
-Zusätzlich gilt eine gemeinsame Sperrzeit von zwei Minuten für beide Antwortarten. Die Sperre wird getrennt je Rufzeichen und Chat-Kategorie geführt. Hat eine Station gerade in der Hauptkategorie eine automatische Antwort erhalten, kann sie deshalb weiterhin eine Antwort in der zweiten Kategorie erhalten. Weitere Nachrichten derselben Station in derselben Kategorie lösen während der folgenden zwei Minuten dagegen keine neue automatische Antwort aus.
-
-Die Sperrzeit beginnt nur, wenn KST4Contest tatsächlich eine Antwort sendet.
-
-> **Hinweis**: Der Antworttext sollte den tatsächlichen Status eindeutig benennen. Wer den Contest nur beobachtet und keine Skeds fahren möchte, sollte genau das mitteilen. Eine vage Nachricht erzeugt im Zweifel nur die nächste Rückfrage – und damit exakt die Arbeit, welche die Funktion vermeiden soll.
-
-Änderungen wirken während der laufenden Verbindung. Damit Aktivierung und Text nach dem nächsten Programmstart erhalten bleiben, anschließend **Save Settings** verwenden.

-**Station Map, Performance, Responsive UI**
-
-**New:**
-- **Station Map**: 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).
-
-**Changed:**
-- **Message table limit raised to 30,000**: Chat and message tables are capped at 30,000 entries. Older messages are automatically discarded, keeping performance stable during multi-day contest operations.
-- **Screen-aware window sizing**: 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.

 ## Cluster & QSO of Others
 
 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.

-## Station Map (from v1.41)
-
-An interactive OpenStreetMap-based map showing the geographic position of all active chat members.
-
-**Features:**
-
-- Station markers with callsign labels, coloured by activity and sked state
-- Antenna **beam cone** visualisation for the own station
-- **Connection line** to the currently selected station
-- **Maidenhead grid** overlay (QRA locator grid)
-- **Path profile chart**: Terrain elevation cross-section between own station and the selected station, including Fresnel zone analysis and obstruction/horizon detection
-- Multiple terrain data sources: **Copernicus GLO-30** (high-resolution DEM), **Open-Meteo API**, synthetic fallback, and **offline DEM import** for air-gapped use
-- Aircraft scatter path analysis integrated with the terrain data
-
-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.
-
----
-
-## Optimised Message Handling / 30,000 Message Limit (from v1.41)
-
-The internal chat and message tables are capped at **30,000 entries**. Older messages are automatically discarded when the limit is reached. This keeps memory usage and rendering performance stable during multi-day contest operations.
-
----
-
-## Screen-Aware Window Sizing (from v1.41)
-
-On startup, KST4Contest calculates a screen-aware size for the main window:
-
-- The stored window size from the previous session is used – but **never larger than the current screen**.
-- If KST4Contest was last used on a larger monitor, the window is automatically scaled down to fit the current display without clipping.
-- The UI layout is more **compact and responsive on smaller screens**, showing the same information in less space.
-
-This prevents unusable oversized windows when switching between machines or monitors.

-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.
+**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 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).
+Developed by **DO5AMF (Marc Fröhlich)**, operator at DM5M.
 
 ---
 
-## 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.

+The ON4KST Chat is the de-facto standard for skeds on the 144 MHz and higher bands. KST4Contest enhances the chat experience with contest-specific features:
 
-### Reporting a bug
+- **Worked marking**: Stations already worked are highlighted visually, synchronised directly from your logging software via UDP.
+- **Sked direction detection**: When a station calls another one from your direction, it is highlighted green and bold.
+- **QRG detection**: KST4Contest automatically reads frequencies from the chat traffic and shows them in the user list.
+- **AirScout interface**: Reflectable aircraft are shown directly in the user list.
+- **Built-in DX cluster server**: Spots are sent directly to your logging software.
+- **Dark mode** (from v1.26): Easy on the eyes during night-time operation.
+- **Multi-channel login** (from v1.26): Simultaneously logged into two chat categories.
 
-A problem is considerably easier to reproduce when the report contains at least:
+---
 
-1. the KST4Contest version,
-2. the operating system and installation method,
-3. the exact steps leading to the problem,
-4. the expected and observed behaviour,
-5. a screenshot where appropriate,
-6. the error log file.
+## Contact & Support
 
-The error log is stored at:
-
-| Operating system | Path |
-|---|---|
-| Linux / macOS | `~/.praktiKST/kst4contest-errors.log` |
-| Windows | `C:\Users\<YourName>\.praktiKST\kst4contest-errors.log` |
-
-Please inspect the file briefly before uploading it. An error log mainly contains technical information, but depending on the problem it may also include local file paths or other contextual data.
-
-Some file and directory names still use the technical name `praktiKST`. They refer to the same program.

 > 🇬🇧 You are reading the English version | 🇩🇪 [Deutsche Version](de-Installation)
 
-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.
+## Prerequisites
 
-In practical terms, you need a supported operating system, an internet connection and an ON4KST account. That sounds manageable—and usually it is.
+An resolution of 1200px by 720px is recommended
 
-## Requirements
+### ON4KST Account
 
-### ON4KST account
+To use the chat, a registered account with the ON4KST chat service is required:
 
-KST4Contest is an independent client for the ON4KST chat, but it does not replace the corresponding user account.
+- Register at: http://www.on4kst.info/chat/register.php
 
-If you do not have an account yet, you can create one on the official ON4KST website:
+### Chat Etiquette
 
-- [ON4KST login and registration](https://www.on4kst.org/chat/login.php)
+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 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.
+### Personal Messages
 
-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.
+To send a private message to another station, always use the following format:
 
-### Screen size
+```
+/CQ CALLSIGN message text
+```
 
-A usable screen area of approximately **1200 × 720 pixels** or more is recommended.
+Example: `/CQ DL5ASG pse sked 144.205?`
 
-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.
+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)).

-Only download application packages from the official GitHub Releases, the KST4Contest Flatpak repository or the linked AUR packages. Files from other sources may have been built differently, may be outdated or may have been modified.
 
 ---
 
-## Installing on Windows
+## Installation
 
-KST4Contest is distributed as a ZIP package for Windows. A conventional installer is not required.
+### Windows
 
-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`.
+1. Download the ZIP file.
+2. Unzip the ZIP file into a folder of your choice.
+3. Run `praktiKST.exe`.
 
-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.
+Settings are stored at `%USERPROFILE%\.praktikst\preferences.xml`.
 
-The application settings are not stored in the extracted program directory. They are stored in your user profile:
+### Linux
+1. Download the AppImage.
+2. Unzip the AppImage into a folder of your choice.
+3. Make the AppImage executable (in the terminal with `chmod +x KST4Contest-v<version_number>-linux-x86_64.AppImage`)
+4. Run the AppImage.
 
-```text
-%USERPROFILE%\.praktiKST\preferences.xml
-```
+Settings are stored at `~/.praktikst/preferences.xml`.
 
-This allows a new application version to be extracted into a different directory without losing the existing settings.
-
----
-
-## 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
-```
-
-Alternatively, open the file with a graphical package manager.
-
-### Fedora and compatible RPM systems
-
-Install the RPM package with:
-
-```bash
-sudo dnf install ./KST4Contest-v<version>-fedora-x86_64.rpm
-```
-
-### 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
-```
-
-### Arch Linux: installing from the AUR
-
-Three variants are available in the AUR:
-
-| 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 |
-
-For most users, `kst4contest-bin` is the straightforward option:
-
-```bash
-yay -S kst4contest-bin
-```
-
-To build the Stable release from source:
-
-```bash
-yay -S kst4contest
-```
-
-To build the current development state:
-
-```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.
+### macOS
+1. Download the DMG file for your architecture (Apple Silicon or Intel).
 2. Open the DMG file.
-3. Drag `KST4Contest.app` into the **Applications** folder.
-4. Start KST4Contest from the Applications folder or Launchpad.
+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.
 
-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**.
+Settings are stored at `~/.praktikst/preferences.xml`.
 
 ---
 
-## Where are the settings stored?
+## Updating
 
-KST4Contest stores its settings and other local working files in the user’s home directory. The application directory and the data directory are separate.
+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.
 
-| Operating system | Data directory | Settings file |
-|---|---|---|
-| Windows | `%USERPROFILE%\.praktiKST\` | `%USERPROFILE%\.praktiKST\preferences.xml` |
-| Linux | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
-| macOS | `~/.praktiKST/` | `~/.praktiKST/preferences.xml` |
+![Example Update Window](update_window.png)
 
-Note the spelling `.praktiKST` with an uppercase `KST`. Linux and macOS distinguish between uppercase and lowercase letters. `.praktikst` would simply be a different directory.
+### 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
+
+Currently as follows:
+1. Download the new AppImage
+2. Mark the new AppImage as executable
+3. (optional) Delete the old AppImage.
+
+#### 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.
 
-An application update does not remove this directory. Even so, creating a backup before a major version change or extensive configuration work is sensible.
 
 ---
 
-## Updates
+## Known Issues at Startup
 
-When KST4Contest starts, it checks whether a newer Stable release is available. If it finds one, it displays an information window containing:
+### Norton 360
 
-- 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.
+Norton 360 classifies `praktiKST.exe` as dangerous (false positive). An exception must be created for the file:
 
-![KST4Contest update notification](update_window.png)
+1. Open Norton 360.
+2. Security → History → Find the corresponding event.
+3. Select "Restore & Add Exception".
 
-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.
