## Why it matters

During active VHF, UHF and microwave contests, relevant stations can disappear quickly in busy ON4KST chat traffic.

The Priority Score System helps operators focus on stations that are more likely to be useful during contest operation.

## Built for contest decisions

KST4Contest is not just a chat viewer. It evaluates contest-relevant context and helps turn chat activity into better operating decisions.
