Frequently Asked Questions
Is City of Donna radio encrypted?
Yes — City of Donna's radio system runs on P25 AES-256 encryption. This is a split system: certain talkgroups are encrypted while others remain in the clear, which means partial monitoring is still possible.
Can I listen to City of Donna on a police scanner?
Partially. City of Donna 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 Donna 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 Hidalgo 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 Hidalgo County reverse the encryption decision?
Yes. Whoever made this call for City of Donna can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.
What can I do about City of Donna encryption?
Start local: show up when Hidalgo County officials discuss the budget for City of Donna, 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.
