We do have per-talkgroup data for Arkansas Valley EMS 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 Arkansas Valley EMS 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 Arkansas Valley EMS radio encrypted?

Arkansas Valley EMS 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 Arkansas Valley EMS on a police scanner?

Possibly. Our database lists Arkansas Valley EMS 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 Arkansas Valley EMS 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 emergency medical services activity in real time, and coordination with agencies that stay unencrypted gets harder.

Can Fremont County reverse the encryption decision?

Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.

What can I do about Arkansas Valley EMS encryption?

Ask for the paperwork first — the policy that authorised encryption for Arkansas Valley EMS, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from Fremont County with you.
