Montgomery, Maryland

How we verified this

The Montgomery County, MD P25 Phase II trunked system's 'Rockville PD Dsp' (B10 Rockville Police Dispatch) talkgroup is flagged ENC. Maryland has no township government, so the real agency is the City of Rockville Police Department, not a 'township police' -- flagging for a name correction alongside the encryption finding.

Frequently Asked Questions

Is Rockville Township Police radio encrypted?

Yes. Rockville Township Police uses P25 AES-256 encryption. All traffic, including the day-to-day dispatch that used to be the public's window into police activity, now runs encrypted. Nothing from this department is receivable.

Can I listen to Rockville Township Police on a police scanner?

No. Rockville Township Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.

Why did Rockville Township Police encrypt their radio?

The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.

Can Montgomery County reverse the encryption decision?

It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by Montgomery County officials are policies those officials can revisit when constituents press for it.

What can I do about Rockville Township Police encryption?

File a FOIA request for Rockville Township Police's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in Montgomery County who want the same access — state legislation requiring public radio access is the longer-term fix, but organized local pressure is what usually moves the needle first.
