Verification Status

We don't yet have per-talkgroup data for Nantucket Police 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 low confidence (50%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Nantucket Police 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 Nantucket Police radio encrypted?

Nantucket Police is listed in our records with P25 DES-OFB 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 Nantucket Police on a police scanner?

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

Why do agencies like Nantucket Police encrypt their radio?

Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Nantucket County; what's verifiable is what's lost — journalists can't monitor police department activity in real time, and coordination with agencies that stay unencrypted gets harder.

Can Nantucket 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 Nantucket Police encryption?

Contact the officials who oversee Nantucket Police'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 Nantucket County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
