Police Department Partially Encrypted

Derry Township Police

Dauphin, Pennsylvania

How we verified this

RR shows a mixed picture: Derry Twp PD talk TG 11201 is clear while Derry Twp PD Ops TG 11810 and the Dauphin County Police 1/2 Dispatch talkgroups are encrypted — the opposite of the input's 'all operations except dispatch' claim, since dispatch is encrypted and a Derry talk TG is clear.

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 Derry Township Police radio encrypted?

Yes — Derry Township Police's radio system runs on 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 Derry Township Police on a police scanner?

Partially. Derry Township 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 Derry Township Police encrypt their radio?

Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Dauphin County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.

Can Dauphin County reverse the encryption decision?

Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.

What can I do about Derry Township Police encryption?

Start local: show up when Dauphin County officials discuss the budget for Derry Township Police, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
