Verification Status
We do have per-talkgroup data for Cambridge Police from the RadioReference API, and used it to set the encryption scope shown above — but no additional human-reviewed source (a live feed check or a dated news account) has been recorded for this record, so treat it as a data-quality correction rather than an independently confirmed verification. Check the live RadioReference database directly for current status.
If you monitor Cambridge 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 Cambridge Police radio encrypted?
Our database lists Cambridge Police as using P25 AES-256 encryption, though this listing is unverified. Our records list a mix here: some talkgroups encrypted, others not. The listing is unverified, so confirm what is audible at RadioReference.
Can I listen to Cambridge Police on a police scanner?
Possibly. Our database lists Cambridge Police as encrypting some of its talkgroups while leaving others open, which would leave some channels accessible. The listing is unverified — check RadioReference for specific talkgroup status.
Why do agencies like Cambridge Police encrypt their radio?
Agencies cite officer safety and operational security. Those are assertions rather than findings — no local evidence is typically produced — while the effects are concrete and land straight away on anyone who relied on hearing Cambridge Police to know what was happening nearby.
Can Middlesex 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 Middlesex County officials are policies those officials can revisit when constituents press for it.
What can I do about Cambridge Police encryption?
File a FOIA request for Cambridge 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 Middlesex 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.
