Pineville PD is dispatched on 851.4125 with a dpl of D054. They also use 155.58, with a dpl of D054, as an informal talk around.
They do show up on the Charlotte TRS on 25968 (Pineville Ch. 4), and 62785 (Pineville Ch. 3). I also hear them on Mutual Aid talkgroup (02064) talking to Charlotte PD. Charlotte's Adam 1 and Baker 2 units will go to Pineville's talkgroups when calls for service overlap each other's jurisdictions.
BTW, thanks for the reply on Mint Hill.
