Frequently Asked Questions

Is City of Anna radio encrypted?

Yes — City of Anna's radio system runs on P25 AES-256 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 City of Anna on a police scanner?

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

Why did City of Anna encrypt their radio?

Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Colin County where an open channel caused harm. The costs need no such documentation: reporting on other agency response slows down, and mutual-aid coordination gets more awkward, immediately.

Can Colin 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 City of Anna encryption?

Start local: show up when Colin County officials discuss the budget for City of Anna, 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.
