Verification Status

We do have per-talkgroup data for El Cajon 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 El Cajon 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 El Cajon Police radio encrypted?

El Cajon 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 El Cajon Police on a police scanner?

Possibly. Our database lists El Cajon 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 El Cajon Police encrypt their radio?

Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is San Diego County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.

Can San Diego County reverse the encryption decision?

Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.

What can I do about El Cajon Police encryption?

Ask for the paperwork first — the policy that authorised encryption for El Cajon 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 Diego County with you.
