Frequently Asked Questions
Is Hercules Police radio encrypted?
Yes — Hercules Police's radio system runs on P25 AES-256 encryption. Only the tactical side is closed. SWAT callouts and sensitive operations are encrypted; ordinary calls for service may still reach a scanner.
Can I listen to Hercules Police on a police scanner?
Partially. Hercules Police encrypts its tactical channels, so some channels may still be accessible. Check RadioReference for specific talkgroup status.
Why did Hercules Police encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Contra Costa County; what's verifiable is what's lost — journalists can't monitor police department activity in real time, and coordination with agencies that stay unencrypted gets harder.
Can Contra Costa 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 Hercules Police encryption?
Ask for the paperwork first — the policy that authorised encryption for Hercules 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 Contra Costa County with you.
