Verification Status

We don't yet have per-talkgroup data for City of Clarksville Police/Fire Department from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at low confidence (50%) based on how closely the wiki listing matches this agency's name and county.

If you monitor City of Clarksville Police/Fire Department 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.

Why do agencies like City of Clarksville Police/Fire Department encrypt their radio?

The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Montgomery County incident is rarely part of the public record, whereas the consequences are easy to observe — no real-time accountability, and neighbouring agencies still in the clear left working around the gap.

Can Montgomery County reverse the encryption decision?

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

What can I do about City of Clarksville Police/Fire Department encryption?

Three things carry weight, in this order: a public-records request for City of Clarksville Police/Fire Department's encryption policy and radio recordings, a turn at the microphone during Montgomery County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
