Fairfax County Police Encrypt Dispatch: DC Scanner Feeds Go Dark

On July 13, 2026, one of the largest police scanner-listening markets in the United States went dark. The Fairfax County Police Department encrypted all eight of its main dispatch channels, while the City of Fairfax Police simultaneously encrypted its primary dispatch channel. The move — announced just three days earlier on July 10 — silences popular feeds on platforms like OpenMHz and Broadcastify, marking a major milestone in the DC region's encryption wave. For the millions of residents and commuters in Northern Virginia, understanding what happened and what they can still hear is critical.

What Happened on July 13, 2026

The Fairfax County Police Department and the City of Fairfax Police Department flipped the switch on P25 encryption simultaneously. The city's official release confirmed dispatch will "no longer be available through scanner applications or online radio streaming services." Popular feeds including the OpenMHz feed for the Fairfax County system went silent immediately. FFXnow first reported the story, noting that the announcement came with minimal public notice.

The DC Region Is Now Nearly Fully Encrypted

With Fairfax County and Fairfax City joining the list, the Washington, D.C. metro area is now almost completely closed to police radio listeners:

• Arlington County Police — already encrypted
• Prince William County Police — already encrypted
• Virginia State Police — already encrypted (and criticized for missing a June 2025 I-395 road-rage shooting report for a month)
• D.C. Metro Police — already encrypted
• Loudoun County — began encryption rollout in July 2026, expected complete by fall

This near-total closure means that the country's capital region — home to over 6 million people — has effectively lost real-time public access to police dispatch information.

What You Can Still Hear in Fairfax County

Not everything went dark on July 13. Several important channels remain in the clear:

• Fairfax County Fire & Rescue frequencies — officials stated there are "no plans" to encrypt primary fire/rescue channels
• Automated 911 pre-dispatch feed — unaffected by the encryption change
• Some mutual-aid channels — may remain accessible depending on incident type
• Airband, FRS/GMRS, NOAA weather radio — all still receivable on any standard scanner

For listeners who want to monitor what remains, a Baofeng UV-5R Plus Police Scanner can still access fire/rescue, EMS, airband, and non-encrypted municipal frequencies across Northern Virginia.

Transparency Concerns Mount

Independent public-safety reporter Larry Calhoun told FFXnow that encryption "absolutely hurts transparency." He pointed to the Virginia State Police's encrypted system, which missed reporting a June 2025 road-rage shooting on I-395 for an entire month. The Loudoun County transparency audit — which found 22 of 27 violent incidents received no public notification — underscores the same pattern: encryption without a transparency plan leaves communities in the dark.

How Encryption Works: P25 and the Technology Behind It

Fairfax County uses Project 25 (P25) digital radio infrastructure, which supports both encrypted and unencrypted talkgroups. Encryption is implemented at the talkgroup level — meaning some channels on the same system can be encrypted while others remain open. This is why Fairfax County Fire & Rescue can stay on the same P25 system with unencrypted channels while police dispatch is fully encrypted. The encryption standard used is typically AES-256, which is effectively unbreakable with consumer equipment.

FAQ

When did Fairfax County police encrypt dispatch?

Fairfax County Police encrypted all eight main dispatch channels on July 13, 2026. The City of Fairfax Police encrypted its primary dispatch channel the same day. The change was announced on July 10.

Can I still listen to Fairfax County Fire & Rescue?

Yes. Fairfax County officials have stated there are "no plans" to encrypt primary fire and rescue channels. These remain in the clear on the same P25 system.

What is OpenMHz and why did my feed stop working?

OpenMHz is a platform that streams unencrypted public-safety radio traffic online. When Fairfax County police encrypted their dispatch channels, those feeds became unavailable to stream because the audio is now scrambled end-to-end.

Is the DC region completely encrypted now?

Nearly, but not entirely. Arlington, Prince William, VSP, D.C. Metro, Fairfax County, and Fairfax City police are all encrypted. Loudoun County is in the process of encrypting. However, fire and rescue channels in most of these jurisdictions remain open.

What scanner do I need to hear what's left in Fairfax County?

A standard police scanner like the Baofeng UV-5R Plus can receive fire/rescue, EMS, NOAA weather, airband, and non-encrypted municipal channels. However, no consumer scanner can decrypt AES-256 encrypted P25 audio.

Will Fairfax County police ever go back to unencrypted dispatch?

Reversing encryption is extremely rare once implemented. The better bet is advocating for transparency alternatives — live call dashboards, delayed feeds, or media access programs similar to what New York City is developing.

The Bottom Line

The Fairfax County police encryption on July 13, 2026, is a watershed moment for the DC-area scanner community. One of America's largest listening markets has gone dark, and the trend shows no signs of reversing. But fire/rescue channels remain open, and a capable scanner can still keep you connected to critical real-time information.
