Verification Status

We don't yet have per-talkgroup data for St. John 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 moderate confidence (70%) based on how closely the wiki listing matches this agency's name and county.

If you monitor St. John 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.

St. Louis County Context

St. John Police isn't an outlier here: 31 of the 32 public-safety agencies we track in St. Louis County are fully encrypted (97%), so most departments nearby have made the same move.

Frequently Asked Questions

Is St. John Police radio encrypted?

St. John Police is listed in our records with P25 ADP 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 St. John Police on a police scanner?

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

Why do agencies like St. John Police encrypt their radio?

Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to St. Louis 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 St. Louis 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 St. John Police encryption?

Ask for the paperwork first — the policy that authorised encryption for St. John Police, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from St. Louis County with you.
