Matthews uses three TRS talkgroups, and are licensed for another on the Charlotte-Mecklenburg system. 1008 is the dispatch channel, 1040 is Patrol 1, 1016 is Patrol 2 and 2000 is listed as Detectives. I have never heard anything on the 2000 talkgroup. Also, Mint Hill PD is dispatched from Matthews. They are dispatched on the main channel, but have their own talkgroup for car to car communications. That is 33616.
