Frequently Asked Questions

Is Alpena County Sheriff radio encrypted?

Yes — Alpena County Sheriff's radio system runs on P25 DES-OFB encryption. Encryption here is a mixed bag: some talkgroups are locked, others aren't. It varies by channel and by what the department is doing at the time.

Can I listen to Alpena County Sheriff on a police scanner?

Partially. Alpena County Sheriff encrypts some of its talkgroups while leaving others open, so some channels may still be accessible. Check RadioReference for specific talkgroup status.

Why did Alpena County Sheriff encrypt their radio?

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

Can Alpena 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 Alpena County Sheriff encryption?

Start local: show up when Alpena County officials discuss the budget for Alpena County Sheriff, 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.
