Verification Status

We do have per-talkgroup data for Round Lake Park 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 Round Lake Park 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

Lake County Context

Lake County is a mixed picture: 10 of 30 agencies we track here are fully encrypted (33%), which means some neighboring departments are still audible on a scanner.

Frequently Asked Questions

Is Round Lake Park Police radio encrypted?

Round Lake Park Police 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 as encrypting some communications while leaving others open. The per-channel breakdown is unverified — check RadioReference for current status.

Can I listen to Round Lake Park Police on a police scanner?

Possibly. Our database lists Round Lake Park 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 Round Lake Park Police encrypt their radio?

Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Lake 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 Lake County reverse the encryption decision?

Yes. Whoever made this call for Round Lake Park Police can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.

What can I do about Round Lake Park Police encryption?

Ask for the paperwork first — the policy that authorised encryption for Round Lake Park 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 Lake County with you.
