Verification Status

We do have per-talkgroup data for Marshall Police from the RadioReference API, and used it to correct this listing’s encryption status — 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 Marshall 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.

Shared Radio System

Calhoun County Context

Calhoun County is a mixed picture: 2 of 5 agencies we track here are fully encrypted (40%), which means some neighboring departments are still audible on a scanner.

What This Means

This agency was previously listed as encrypted, but its own RadioReference talkgroup data (reviewed 2026-09-28) shows 0% of its talkgroups actually encrypted. Any scanner can receive it — confirm current status on the live RadioReference database, since encryption decisions can change.

Frequently Asked Questions

Is Marshall Police radio encrypted?

No. Despite earlier listings, Marshall Police broadcasts in the clear. This agency was previously listed as encrypted, but its own RadioReference talkgroup data (reviewed 2026-09-28) shows 0% of its talkgroups actually encrypted. Any scanner can receive it — confirm current status on the live RadioReference database, since encryption decisions can change.

Can I listen to Marshall Police on a police scanner?

Yes. Marshall Police's own RadioReference talkgroup data shows its dispatch broadcasting in the clear — any scanner can receive it. Check RadioReference for frequencies and current status.

Why do agencies like Marshall Police encrypt their radio?

The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Calhoun County incident is rarely part of the public record, whereas the consequences are easy to observe — no real-time accountability, and neighbouring agencies still in the clear left working around the gap.

Can Calhoun County reverse the encryption decision?

Nothing technical prevents it. Marshall Police operates encrypted because someone decided it should, and decisions of that kind get revisited when councils hear sustained, organised pressure rather than isolated complaints.

What can I do about Marshall Police encryption?

File a FOIA request for Marshall 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 Calhoun 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.
