If you monitor Deer Mountain 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.

Frequently Asked Questions

Is Deer Mountain Fire Department radio encrypted?

Deer Mountain Fire Department is listed in our records with P25 ADP encryption — a listing we haven't yet verified against live talkgroup data. This agency is listed as encrypting some communications while leaving others open. The per-channel breakdown is unverified — check RadioReference for current status.

Can I listen to Deer Mountain Fire Department on a police scanner?

Possibly. Our database lists Deer Mountain Fire Department as encrypting some of its talkgroups while leaving others open, which would leave some channels accessible. The listing is unverified — check RadioReference for specific talkgroup status.

Why do agencies like Deer Mountain Fire Department encrypt their radio?

Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Fremont County; what's verifiable is what's lost — journalists can't monitor fire department activity in real time, and coordination with agencies that stay unencrypted gets harder.

Can Fremont County reverse the encryption decision?

Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.

What can I do about Deer Mountain Fire Department encryption?

Start local: show up when Fremont County officials discuss the budget for Deer Mountain Fire Department, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
