Verification Status

We don't yet have per-talkgroup data for Plymouth Police Department from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at moderate confidence (70%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Plymouth Police Department directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Frequently Asked Questions

Is Plymouth Police Department radio encrypted?

Plymouth Police Department is listed in our records with P25 AES-256 encryption — a listing we haven't yet verified against live talkgroup data. This agency is listed in our database as encrypting all of its radio communications, including routine dispatch. The listing is unverified — confirm current status on the live RadioReference database.

Can I listen to Plymouth Police Department on a police scanner?

Likely not, if the listing is accurate: our database lists Plymouth Police Department as fully encrypted using P25 AES-256, which no consumer scanner can decode. The listing is unverified — check the live RadioReference database for current status.

Why do agencies like Plymouth Police Department encrypt their radio?

Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Hennepin 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 Hennepin 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 Plymouth Police Department encryption?

Contact the officials who oversee Plymouth Police Department's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Hennepin County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
