I suppose I could be wrong but I'd swear I heard digital sounding C-PTL traffic driving through the city 6-9 months ago and looked down and saw it was on the Worcester system.I don't think I've ever heard the Patrol Channels (main C Troop MSP talk groups) on the city system. LPS, Event, and some peripheral stuff, yeah. SOPS? Don't think so, but C-Ptl-1, 2, 3? I don't think ever.
