Caldwell Parish Sheriff Dispatch - talkgroup 50000 on LWIN 700Mhz radio system.

Columbia Police, Grayson Police, and Clarks Police are also dispatched on the SO Dispatch channel.

Update: Apr 2 2025: CPSO has recently started using a computer-aided dispatch (CAD) system and is using that to dispatch calls, run license plates, conduct traffic stops, etc. You may have noticed a sharp decline in the overall amount of radio traffic, and this is why.
