Verification Status
We do have per-talkgroup data for Costa Mesa Police 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 Costa Mesa Police 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 Costa Mesa Police radio encrypted?
Costa Mesa Police is listed in our records with P25 AES-256 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 Costa Mesa Police on a police scanner?
Possibly. Our database lists Costa Mesa Police 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 Costa Mesa 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 Orange 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 Orange County reverse the encryption decision?
Yes. Whoever made this call for Costa Mesa 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 Costa Mesa Police encryption?
Contact the officials who oversee Costa Mesa Police's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Orange County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
