Frequently Asked Questions
Is SUIE Police radio encrypted?
Yes. SUIE Police uses P25 AES-256 encryption. Encryption applies to named channels here, not across the board. Everything outside those specific talkgroups can still be received.
Can I listen to SUIE Police on a police scanner?
Partially. SUIE Police encrypts specific talkgroups rather than the whole system, so some channels may still be accessible. Check RadioReference for specific talkgroup status.
Why did SUIE 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 Madison 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 Madison County reverse the encryption decision?
Yes — nothing about the underlying radio technology forces this. It's a decision Madison County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.
What can I do about SUIE Police encryption?
Put the question to whoever signs off on SUIE Police's radio budget: why full encryption rather than a delayed feed or tactical-only channels? File for the recordings and the decision documents alongside it, and link up with neighbours and local reporters in Madison County so the ask arrives as a group rather than a one-off.
