Santa Rosa police scanner: fully encrypted
Santa Rosa PD and most Sonoma County law enforcement agencies encrypted communications in 2020 when the county upgraded its radio system. Here's what's accessible, what isn't, and how to push for transparency.
Sonoma County at a Glance
When Sonoma County upgraded its radio infrastructure to a P25 digital system around 2020, law enforcement agencies used the transition to encrypt—citing officer safety without providing incident-specific evidence that open communications had caused problems.
Santa Rosa, the county seat with over 175,000 residents, is part of that encrypted system. Journalists, community members, and emergency watchdogs who relied on scanner access for real-time information no longer have it.

Why Santa Rosa's encryption matters
Wildfire country
Sonoma County burned badly in the 2017 Tubbs Fire and the 2019 Kincade Fire. Scanner access let residents track fire boundaries and make evacuation decisions in real time. Official alerts lag behind what officers are saying to each other on the radio.
Press access
The Press Democrat and other local journalists used scanner access to cover breaking news. That's gone. They now depend on PIO statements, which arrive late and are written to manage the story.
Accountability gap
Santa Rosa PD has faced scrutiny over use-of-force incidents. Encrypted radios mean no one outside the department hears how officers communicate during critical encounters.
Part of a larger pattern
Sonoma County's encryption fits the Bay Area trend. The Bay Area, Los Angeles, and San Diego have all moved in this direction. The cumulative effect is a statewide accountability gap.
Pushing for transparency in Sonoma County
Encryption has been reversed before. Other communities have forced policy changes or negotiated compromises. Sonoma County residents have the same options:
Board of Supervisors meetings
The Sonoma County Board of Supervisors oversees the Sheriff's Office and the county radio system. Public comment periods are direct access to the officials who set policy.
Santa Rosa City Council
City Council has authority over SRPD policy. Ask council members to require delayed audio release or other transparency measures as alternatives to total encryption.
Support The Press Democrat
The local paper is doing more with less access. Supporting local journalism that covers law enforcement means supporting the people who still have standing to demand answers.
Public Records Act requests
Use California's Public Records Act to request incident reports, use-of-force data, and communications policies. Scanner access is gone, but records access isn't.
Bay Area scanner access beyond Sonoma
Marin County
San Rafael PD, Marin County Sheriff, and smaller agencies all use encrypted P25 systems. Most of Marin is dark.
San Francisco
SFPD encrypted in 2022. Credentialed journalists have access through a media program; the public does not. Some fire and transit channels remain open.
Napa County
Napa County law enforcement followed the Bay Area trend to encrypted communications.
Lake County
Some agencies in rural Lake County to the north remain more accessible. Check RadioReference for current status.
Frequently Asked Questions
Is Santa Rosa Police Department radio encrypted?
Yes. The Santa Rosa Police Department has been fully encrypted since 2020 when Sonoma County migrated to an encrypted P25 digital radio system. No public scanner can access SRPD communications.
Can I listen to Santa Rosa police on a scanner?
No. Santa Rosa PD uses AES-256 encryption on the Sonoma County P25 system, making it impossible to monitor with any consumer scanner. This applies to dispatch, patrol, and all operational channels.
What scanner do I need for Santa Rosa area agencies?
Unfortunately, no scanner will work for Santa Rosa PD or most Sonoma County law enforcement. These agencies use encrypted P25 Phase II systems. You may be able to monitor some fire communications with a digital scanner capable of P25, such as the Uniden SDS100.
When did Santa Rosa police encrypt their radios?
Santa Rosa PD encrypted their communications around 2020 as part of the Sonoma County regional radio system upgrade. The county cited officer safety and operational security as justifications.
Is Sonoma County Sheriff encrypted?
Yes. The Sonoma County Sheriff's Office is fully encrypted on the county P25 system. All dispatch, patrol, and investigative communications are inaccessible to the public.
Can I listen to Santa Rosa Fire Department?
Partially. Some Santa Rosa Fire and Sonoma County fire dispatch communications remain unencrypted and can be monitored with a P25-capable scanner. However, coordination with law enforcement and some tactical operations may be encrypted.
Why did Sonoma County encrypt police radios?
Sonoma County cited officer safety, protection of sensitive information, and preventing criminals from monitoring police activities. However, transparency advocates argue encryption reduces accountability and public oversight of law enforcement.
Are there any unencrypted agencies in Sonoma County?
Most law enforcement in Sonoma County is encrypted. Some fire and EMS communications remain accessible. Check RadioReference.com for current status, as encryption policies can change.
