What's On The Air

Every talkgroup that's carried traffic in the selected window, ranked by how busy it's been. Green is clear — listenable. Red is encrypted — active on the air, but scrambled and not listenable by anyone. Counts are keyups (PTT), deduplicated so a transmission heard by multiple sites counts once.

This shows activity, not audio. Encrypted talkgroups appear here because they're on the air — NCISS never decodes them and never could. We show you the whole radio system, including the parts you can't hear. Data refreshes every few minutes and runs a few minutes behind real time.
