800 MHz 9600 Baud Control Channel in North Bryan?

On Friday, I passed through North Bryan County on GA 204 and US 280. While going through the area, I had the BC396 doing a 700 MHz and 800 MHz search. It stumbled across what seemed to be a 9600 baud Motorola Control Channel on 866.1125. I didn't hear any voice activity and the 396 didn't get a System ID off of it either, so I can't be sure that is what it was. It did lock on the freq and display "DAT" like it does on a 9600 Baud Control Channel though. The interesting thing is that I can't find anything on it in the FCC database...
