Verification Status

We do have per-talkgroup data for San Jose Incident Command System from the RadioReference API, and used it to set the encryption scope shown above — but no additional human-reviewed source (a live feed check or a dated news account) has been recorded for this record, so treat it as a data-quality correction rather than an independently confirmed verification. Check the live RadioReference database directly for current status.

If you monitor San Jose Incident Command System directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Yes — nothing about the underlying radio technology forces this. It's a decision Santa Clara County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.
