The contest-optimized ON4KST client
+ON4KST contest workflow for 144 MHz and above
- Work smarter. Make more QSOs. KST4Contest brings priority candidates, - AirScout workflow, sked reminders, dual chat categories and log synchronization - into one contest-focused ON4KST client. + ON4KST shows you the traffic. KST4Contest helps turn it into an operating + decision by combining chat, candidate prioritisation, sked planning, + AirScout data and logger integration in one desktop client. +
+ ++ The available information is filtered, related to active stations and + presented in a contest-oriented workflow. The final decision still + belongs to the operator.
Powerful features
-The operating problem
+- Every feature is designed to reduce operator workload and improve decision speed during real contest operation. + During an active contest, messages, sked requests, frequency information + and band changes arrive continuously. The task is to identify which part + of that traffic matters now, which candidate should be monitored and + which contact is better scheduled for later. +
++ Messages, locators, detected frequencies and known band activity are + assigned to stations across as many as two ON4KST chat categories. +
++ Direction, distance, worked status, NOT-QRV information, chat activity, + sked context and aircraft scatter data feed filters and candidate scores. +
++ Candidates can be contacted, scheduled or monitored. Skeds remain + visible, while supported loggers and station interfaces receive the + information required for the next operating step. +
+Functions
++ The individual functions are not isolated tools. They use the same + station, message, band and timing information, so that a change in one + part of the workflow can also affect filters, priorities and reminders.

-Limits
+- KST4Contest is developed around real VHF/UHF/SHF contest workflows: - ON4KST chat, aircraft scatter, skeds, logging and fast operator decisions. + KST4Contest can only evaluate the information it knows. Scores, AP + windows, filters and path profiles support the operator's decision; they + do not guarantee a contact. If the input data is incomplete or outdated, + the result can be incomplete or outdated as well.
+ +Project status
++ KST4Contest is open-source software. The current stable release is the + normal choice for contest operation. Nightly builds follow ongoing + development and are useful when a particular fix or feature needs + testing. A few minutes before a contest is not the ideal time to discover + what changed. +
