jpackage cannot produce a distributable macOS bundle on its own. It ad-hoc signs the embedded runtime and then re-runs codesign on the same files without --force, which codesign rejects; and "--type dmg --app-image" re-signs the app it is handed, replacing a Developer ID signature with an ad-hoc one. So the build now creates an unsigned app-image, signs it from the inside out, and wraps it with hdiutil. Apple's notary service also unpacks JARs and checks the native libraries inside them, which sqlite-jdbc ships for both architectures. Those are signed before the bundle is sealed, since rewriting a JAR afterwards would invalidate the seal. A preflight check verifies Apple's two criteria locally, so a missed binary costs seconds rather than a round trip to the notary service. Two long-standing defects surfaced while testing and are fixed here: the bundle identifier defaulted to the main class's package name (kst4contest.view instead of de.x08.KST4Contest), and every release reported version 1.0 in Finder because --app-version was never passed. Neither affects existing users: the app keeps its settings in ~/.praktiKST, independent of the bundle ID. Both workflows call the same script the local Mac uses, so the two cannot drift apart. Signing needs a keychain that can answer a UI prompt, which a runner cannot, so ci-import-cert.sh creates a throwaway keychain whose password is generated per job and discarded with it. Notarization goes through an App Store Connect API key and needs no keychain at all.

KST4Contest
KST4Contest is a Java-based client for the ON4KST chat, developed for coordinated VHF, UHF and microwave contest operation.
The application is developed by Marc Fröhlich (DO5AMF) and since 2026 Philipp Wagner (DN9APW).

What KST4Contest does
KST4Contest combines the ON4KST chat with information that is useful when coordinating contacts during a contest.
Among other things, it can:
- display and filter stations from the supported ON4KST chat categories;
- derive band and frequency information from chat messages and station names;
- maintain Worked and NOT QRV information for the available bands;
- calculate station priorities from distance, activity and other available information;
- manage internal skeds and received Win-Test skeds;
- use AirScout information when evaluating possible aircraft-scatter contacts;
- display stations, paths and additional propagation information on maps;
- exchange information with supported logging programs, Win-Test, PSTRotator and a local DX Cluster interface;
- provide configurable automatic replies for recurring chat requests.
Calculated scores, aircraft-scatter information and path assessments are operating aids. They depend on the available data and should not be treated as guarantees that a contact is possible.
Installation
Ready-to-use packages are available for Windows, Linux and macOS. These packages include the required Java runtime, so a separate Java installation is normally not necessary.
Use the central download page to select the appropriate build:
- Stable is intended for normal contest operation.
- Beta contains changes that are being prepared for a stable release.
- Nightly contains the latest automated development build and is mainly intended for testing.
Documentation
The documentation is available in German and English:
The Markdown sources used for the wiki and the generated PDF manuals are stored in github_docs.
Changes to operating behaviour should be documented together with their purpose and limitations. This is especially important for functions whose result depends on external data, heuristics or information derived from chat messages.
Building from source
Building KST4Contest requires JDK 21. The Maven Wrapper included in the repository should be used, so a separate Maven installation is not required.
Linux and macOS:
./mvnw clean test
./mvnw -B -DskipTests compile
Windows:
mvnw.cmd clean test
mvnw.cmd -B -DskipTests compile
