These controls help you manage what you hear while monitoring live traffic:

  • Pause — pause playback (traffic can still queue)
  • Replay Last — replay the most recent transmission
  • Skip Next — skip the next transmission in the queue
  • Avoid Talkgroup — temporarily avoid the last talkgroup
  • Add Favorite — save the last talkgroup to Favorites

Click Playback to listen to previously recorded traffic. Choose a system, then select a talkgroup to replay audio.

Alerts

The Alerts section lets you configure notifications such as tone-outs or keyword-based alerts (subscription required).

Important: Alerts are still evolving and may change. Always verify alerts by listening to audio and confirming with official sources.
