Santa Rosa Police Scanner: Fully Encrypted
Santa Rosa PD and most Sonoma County law enforcement agencies have encrypted their radio communications, blocking public access. Here's what you need to know and how you can advocate for transparency.
Sonoma County at a Glance
Sonoma County has largely shut out public radio monitoring. When the county upgraded to a new P25 digital radio system, law enforcement agencies chose to encrypt their communications—citing officer safety concerns that transparency advocates argue are overstated.
Santa Rosa, the county seat and largest city with over 175,000 residents, is part of this encrypted system. Journalists, emergency responders, and community members who once relied on scanner access for real-time information are now in the dark.

Why Santa Rosa's Encryption Matters
Wildfire Country
Sonoma County has experienced devastating wildfires including the 2017 Tubbs Fire and 2019 Kincade Fire. Real-time scanner access historically helped residents make evacuation decisions. Now they wait for official alerts that may come too late.
Press Freedom
Local journalists at The Press Democrat and other outlets once monitored scanners to cover breaking news. Encryption forces them to rely on official statements, reducing independent verification of police accounts.
Accountability Gap
Santa Rosa PD has faced scrutiny over use-of-force incidents. Encrypted radios mean the public cannot independently hear how officers communicate during critical encounters.
Regional Trend
Sonoma County's encryption is part of a broader California trend. The Bay Area, Los Angeles, and San Diego regions have all moved toward encrypted communications, creating a statewide accountability crisis.
Fight for Transparency in Sonoma County
Encryption isn't irreversible. Other communities have successfully pushed back against radio encryption or negotiated transparency compromises. Here's how Sonoma County residents can advocate for change:
Attend Board of Supervisors Meetings
The Sonoma County Board of Supervisors oversees the Sheriff's Office and county radio system. Public comment periods are your opportunity to raise transparency concerns.
Contact Your City Council
Santa Rosa City Council has authority over SRPD policy. Request that council members explore delayed audio release or other transparency measures as alternatives to total encryption.
Support Local Journalism
The Press Democrat and other local outlets need public support to continue investigating law enforcement. Independent journalism is even more critical when scanner access is blocked.
File Public Records Requests
Use California's Public Records Act to request police incident reports, use-of-force data, and communications policies. What you can't hear, you can sometimes still read.
Beyond Sonoma: Bay Area Scanner Access
Marin County
Most Marin County law enforcement is also encrypted. San Rafael PD, Marin County Sheriff, and smaller agencies use encrypted P25 systems.
San Francisco
SFPD encrypted in 2022, ending decades of public access. Only some fire and transit communications remain accessible.
Napa County
Napa County law enforcement has also moved to encrypted communications. The wine country region follows the broader Bay Area encryption trend.
Lake County
Some agencies in rural Lake County to the north may have more accessible communications. Check RadioReference for current status.
