Both manuals get the Colours tab in full: the six roles, that a change applies at once but survives a restart only after Save settings, the three ways back with their keyboard shortcuts, what each provenance label means, and the readability notice that warns without refusing. Two things an operator would otherwise have to discover. The reset button is always drawn in the shipped colours and works when nothing else can be read -- the risk section of the design says plainly that a keyboard path only helps whoever knows it, so the manual is where this has to be written down. And the root profile already has both stylesheet files, because KST4Contest has been writing them at startup for years, so most of its roles report "from file" rather than "shipped" with identical values. PROJECT_CONTEXT.md records the decisions that outlive this stage: the three sources and their precedence, that a role is a selector and a property, that the theme must read the store's state rather than remember, where the contrast pairs come from, why the root profile's file layer always exists, and why the lifeline refuses the active palette. Also corrects its claim that CSS stays global -- a profile now owns its stylesheets. The design document and the implementation plan are kept as they were written, including the plan's own corrections where measuring the code contradicted it.
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
