The Scanner Hobby Is Under Threat—Here's What You Can Do
You bought the scanner. You learned the codes. You programmed the frequencies. But across America, police departments are going dark—and no technology can save your hobby. Only advocacy can.
The Numbers Don't Lie
Departments that have blocked public access to their radio communications
Of the 100 largest U.S. cities, over 40% have some level of encryption
Most encryption happened in just 6 years—and it's accelerating
If you've been a scanner hobbyist for years, you've watched this happen in real time. One day your local PD shows up on RadioReference as "encrypted." Then the county sheriff. Then neighboring jurisdictions. The map keeps getting darker.
This isn't paranoia. This isn't a few isolated incidents. This is a national trend that threatens to eliminate public access to police communications entirely within a decade unless something changes.
Why This Is Happening
Understanding why encryption is spreading helps explain how to stop it. The reasons are less about technology and more about politics.
The P25 Upgrade Cycle
Federal grants pushed departments toward digital P25 radio systems. P25 makes encryption trivially easy—it's just a checkbox in the software. When departments upgrade, encryption often comes as a "free" add-on that administrators enable by default.
Post-2020 Accountability Avoidance
Scanner traffic during 2020 protests exposed police misconduct in real time. Within months, many of those same departments encrypted. The timing wasn't coincidental—encryption prevents the kind of independent monitoring that led to viral videos and news coverage.
The "Officer Safety" Narrative
Departments claim encryption protects officers from criminals with scanners. But there's zero documented evidence of scanner-related officer harm in the 100-year history of public police radio. It's a talking point, not a fact.
Path of Least Resistance
Encrypting is easy—it requires no public input, no vote, no debate. Reversing encryption requires organized community pressure. Departments encrypt because they can, not because they must.
Why Technology Can't Save Us
The Hard Truth
No scanner—no matter how expensive—can decode AES-256 encrypted radio. No SDR software, no hacked firmware, no "special" antenna. The encryption is mathematically unbreakable with current technology.
This is important to understand because it changes what solutions are available:
- That $700 Uniden SDS100? It will display "ENCRYPTED" and play silence.
- That SDR setup you spent weeks configuring? It can receive the signal but not decode it.
- That guy on a forum selling "encryption keys"? He's a scammer. Real keys are tightly controlled and never leaked.
- Waiting for technology to catch up? AES-256 will be unbreakable for centuries. Quantum computers won't help.
When technology can't solve a problem, the solution is always the same: policy change. That means politics. That means advocacy. That means you.
What's Still Accessible
The picture isn't entirely bleak. Many agencies remain open, and understanding the patterns helps you know what to expect—and what to protect.
Fire & EMS
Most fire and EMS departments remain unencrypted nationwide. They have less incentive to hide and strong interoperability needs that encryption complicates.
Rural & Small Town
Smaller departments often lack the budget or technical capability for encryption. Many rural sheriffs see no reason to encrypt.
Some Major Metros
San Antonio, Tampa, Fort Worth, and other major cities remain open. These prove that major metros can function without encryption.
State Agencies
State police and highway patrol are increasingly encrypted. California Highway Patrol, Texas DPS, Florida Highway Patrol—all dark.

Prepare to SpeakFrom Hobbyists to Advocates
Here's the uncomfortable truth: if you want to keep listening, you need to start talking. Scanner hobbyists have unique knowledge and credibility that makes them powerful advocates.
What Scanner Hobbyists Bring to Advocacy
- Technical credibility: You understand radio systems better than city council members
- Historical perspective: You remember when everything was open
- Community connections: You know fire chiefs, EMS crews, amateur radio operators
- Documentation: You've seen the transition happen in real time
- Passion: This isn't abstract to you—it's your hobby under attack
You don't need to become a full-time activist. Even small actions matter:
Know Your Local Status
Check which agencies near you are encrypted, which are open, and which are considering changes.
Monitor Local Government
Watch city council and county commission agendas for radio system discussions or "communication security" items.
Build Local Connections
Connect with local journalists, neighborhood watch groups, and emergency management contacts who share your concerns.
Speak Up When It Matters
When encryption comes up, attend the meeting. Submit written comments. Your technical knowledge matters.
Success Stories: Proof That Advocacy Works
If you think fighting encryption is hopeless, you're wrong. Communities have won these battles.
Berkeley, California
After community outcry over planned encryption, Berkeley reversed course and maintained open dispatch channels. Public comment at city council meetings made the difference.

Palo Alto initially encrypted, then reversed the decision after sustained community pressure and media coverage highlighted the transparency concerns.

Local Law 46 now requires NYPD to provide some level of media access to radio communications. It's not perfect, but it's progress won through advocacy.
Read about Local Law 46 →These victories share common elements: organized community members, media attention, persistent pressure, and showing up when decisions were made. None of it required special technology—just civic engagement.
Take Action Today
Your scanner hobby gave you knowledge that most people don't have. Now use it. The future of public access to police communications depends on people like you deciding that this matters enough to act.
Frequently Asked Questions
Is the scanner hobby dying?
The hobby isn't dying—it's being killed. Police encryption has eliminated access in over 3,200 departments since 2018. While some areas remain open, the trend is toward total darkness unless communities organize to stop it.
Can I still listen to police scanners anywhere?
Yes, many areas remain accessible. Fire and EMS are usually unencrypted nationwide. Many rural departments, smaller cities, and some major metros (San Antonio, Tampa, Fort Worth) remain open. Check our agencies database or RadioReference for your area.
Why should scanner hobbyists care about advocacy?
Because no technology can defeat encryption. The only way to restore access is through policy change—city council decisions, state legislation, and public pressure. Hobbyists who want to continue their hobby need to become advocates.
Have any cities reversed encryption?
Yes. Berkeley, Palo Alto, and other California cities reversed encryption decisions after public outcry. NYC passed Local Law 46 requiring partial access. These victories prove advocacy works—but they require organized community effort.
What can one scanner hobbyist do?
More than you think. Attend one city council meeting. Write one letter to your commissioner. Connect with one local journalist. Share your story. Join our community. Individual actions add up to collective pressure that changes policy.
