What the removal left open (4 commits). Compose's MenuBar is a javax.swing.JMenuBar set on the window, so Swing draws it and no theme reaches it; with no look-and-feel configured that meant the default Metal menu above a themed window. The bar is drawn in the window now, except on macOS, where the system bar is where that platform expects it. Two renderers read one description -- mainMenuModel is a plain function of the state, which also gives the menus their first tests. Closing the main window quits the application again, and the window writes its size back to the profile; both had quietly stopped working when the last JavaFX stage went. Then Etappe 7. Four faults shipped in the settings-window branch alongside a green suite of 382 tests, because not one of those tests drew anything: a control that never redrew, a tab strip that clipped mid-word, a form taller than its window with no way down, and colours that came from Material rather than the stylesheet. One regression test per class, and the spec's acceptance criterion is met rather than assumed -- each fault was put back deliberately and the matching test watched to fail. The CI had never run the suite at all; it does now, headless. What that took was not Xvfb: skiko's native library links against libGL and only has to be loadable, since the drawing tests render in software. Without the package the whole Compose half of the suite dies with a message that reads like a missing display. Found by running the job under act rather than on GitHub. The six tests that open a real window skip headless by their own guard. The summary step counts from the result XML and fails on failures there, because this project's rule is never to infer a green suite from an exit code.
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 Gradle Wrapper included in the repository should be used, so a separate Gradle installation is not required.
Linux and macOS:
./gradlew clean build
Windows:
.\gradlew.bat clean build
