Frequently Asked Questions
Is Manteca Police radio encrypted?
Yes — Manteca Police's radio system runs on P25 DES-OFB encryption. Encryption applies to named channels here, not across the board. Everything outside those specific talkgroups can still be received.
Can I listen to Manteca Police on a police scanner?
Partially. Manteca Police encrypts specific talkgroups rather than the whole system, so some channels may still be accessible. Check RadioReference for specific talkgroup status.
Why did Manteca Police 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 San Joaquin County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.
Can San Joaquin County reverse the encryption decision?
Yes. Whoever made this call for Manteca Police 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 Manteca Police encryption?
Ask for the paperwork first — the policy that authorised encryption for Manteca Police, 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 San Joaquin County with you.
