Frequently Asked Questions
Is Decatur Police radio encrypted?
Yes. Decatur Police uses P25 AES-256 encryption. Every channel this agency runs, including day-to-day dispatch, is encrypted. That shuts out the public and local reporters, and it can complicate coordination with nearby agencies that still expect to hear it.
Can I listen to Decatur Police on a police scanner?
No. Decatur Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Decatur Police encrypt their radio?
The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.
Can Macon 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 Macon County officials are policies those officials can revisit when constituents press for it.
What can I do about Decatur Police encryption?
Put the question to whoever signs off on Decatur 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 Macon County so the ask arrives as a group rather than a one-off.
