Police Department Partially Encrypted Discovered via RadioReference

Round Rock Police

Williamson, Texas

How we verified this

On the GATRRS page 11 Round Rock PD talkgroups are flagged D Enc — both dispatches (N/S CMD), Tac 1-6, CID, Special Ops, and Secure — matching the listed count, but the Emergency, Dell Diamond ops, and Training talkgroups carry no encryption flag, so 'all' is not fully supported.

Williamson County Context

Williamson County is a mixed picture: 3 of 6 agencies we track here are fully encrypted (50%), which means some neighboring departments are still audible on a scanner.

What This Means

Coverage here is uneven — parts of the system are locked and parts are open, so a scanner gives you an incomplete rather than an empty picture.

Frequently Asked Questions

Is Round Rock Police radio encrypted?

Yes. Round Rock Police uses P25 AES-256 encryption. Coverage here is uneven — parts of the system are locked and parts are open, so a scanner gives you an incomplete rather than an empty picture.

Can I listen to Round Rock Police on a police scanner?

Partially. Round Rock Police encrypts some of its talkgroups while leaving others open, so some channels may still be accessible. Check RadioReference for specific talkgroup status.

Why did Round Rock 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 Williamson 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 Williamson County officials are policies those officials can revisit when constituents press for it.

What can I do about Round Rock Police encryption?

Three things carry weight, in this order: a public-records request for Round Rock Police's encryption policy and radio recordings, a turn at the microphone during Williamson County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
