Michigan Police Encryption Wave: MSP & Oakland County Go Dark
Michigan has become the largest metro market yet to go dark for scanner listeners: Michigan State Police North and South posts and all Oakland County police departments are now fully encrypted, cutting off journalists and scanner apps across metro Detroit. The wave is rolling out ahead of the October 26, 2026 federal compliance date, with Port Huron and other agencies joining as the state pushes criminal-justice radio traffic onto encrypted channels. Here's what's happened so far, who's next, and what you can still hear.
MSP and Oakland County: Already Dark
Michigan State Police posts and every Oakland County police department have gone fully encrypted, according to Metro Detroit News. Local reporters say the loss of real-time dispatch audio leaves them reliant on after-the-fact police statements instead of live information. The change is the biggest metro-area encryption rollout in the country so far — and it's visible to listeners immediately: MSP and Oakland County audio has disappeared from Broadcastify and scanner apps, not just from over-the-air monitoring.
The October 26, 2026 Deadline Behind the Wave
The shift is driven by an FBI mandate with an October 26, 2026 compliance date, as reported by FOX 2 Detroit. A Metro Detroit News photojournalist told FOX 2 the change "is gonna definitely hinder our operation," urging agencies to keep dispatch clear and encrypt only a secondary channel. That mirrors what we outlined in Police Radio Encryption Deadline: What You Can Still Hear After October 26, 2026 — the federal deadline is pushing agencies nationwide to encrypt, and the window to plan around it is closing.
Port Huron and the Statewide Rollout
The wave is state-driven. Port Huron police began encrypting the week of April 21, 2026, citing Michigan State Police CJIS guidance requiring criminal-justice information to be encrypted when transmitted over land-mobile radio, as reported by the Times Herald. That guidance is the same CJIS policy family behind the broader national shift we covered in CJIS 2027 Deadline: Why Police Radios Are Going Dark.
What Listeners and Journalists Lose
Detroit broadcaster WWJ 950 reports Michigan State Police radios are now unreachable by scanners and scanner apps alike, with Oakland County "already fully encrypted" and additional agencies moving ahead of the federal compliance deadline. Some social-media confirmations are undated, but the core milestones were reported between February and April 2026, and the rollout is ongoing through the October 26, 2026 deadline.
- MSP North and South posts: fully encrypted, audio gone from Broadcastify and scanner apps.
- Oakland County: all police departments fully encrypted.
- Port Huron: began encrypting the week of April 21, 2026, citing MSP CJIS guidance.
- Metro Detroit journalists: now reliant on after-the-fact statements instead of live dispatch audio.
What You Can Still Hear in Michigan
Encrypted talkgroups cannot be received by any scanner or scanner app — once an agency flips that switch, the audio is gone for everyone, including journalists. But not every agency in Michigan has encrypted yet:
- Fire and EMS dispatch in many communities remains unencrypted and fully scannable.
- Agencies that haven't adopted encryption still transmit clear P25 or analog dispatch that any police scanner can receive.
- For communities where dispatch is still clear, a budget-friendly pre-programmed option like the Baofeng UV-5R Plus lets you monitor local channels out of the box.
FAQ: Michigan Police Encryption
Why are Michigan agencies encrypting their radios?
Agencies cite Michigan State Police CJIS guidance requiring criminal-justice information to be encrypted when transmitted over land-mobile radio, behind an FBI mandate with an October 26, 2026 compliance date.
Which Michigan agencies are already encrypted?
Michigan State Police North and South posts and all Oakland County police departments are fully encrypted. Port Huron police began encrypting the week of April 21, 2026, and additional agencies are rolling out ahead of the federal deadline.
Can any scanner hear encrypted police radio?
No. Encrypted traffic cannot be decoded by any scanner or scanner app. When a channel is encrypted, it's gone from over-the-air monitoring and online feeds like Broadcastify alike.
Are scanner apps affected too?
Yes. MSP and Oakland County audio has already disappeared from Broadcastify and scanner apps — the feeds die at the same time the over-the-air signal is encrypted.
How are journalists coping with the loss of dispatch audio?
Local reporters say they now rely on after-the-fact police statements instead of real-time dispatch audio, and some have urged agencies to keep dispatch clear and encrypt only a secondary channel.
When is the federal encryption deadline?
The FBI mandate behind the Michigan wave targets an October 26, 2026 compliance date, and the rollout is ongoing through that deadline.
Bottom line: Michigan's encryption wave has already silenced the state's biggest metro market — MSP and Oakland County audio is gone from scanners, apps, and Broadcastify, and more agencies are flipping the switch before October 26, 2026. If your local agencies haven't encrypted yet, the time to monitor them is now; once they do, no scanner on the market can bring that audio back.
