I'm in Norfolk and I haven't heard anything on the Simcoe AMB talkgroup 35632 for awhile. Even when in Brantford I didn't hear anything. Usually it's very active. PSRN is not active in Brant or Norfolk county as far as I'm aware.
Yes this is the case. The PSRN CC for Simcoe is 142.440, which is the alternate on FleetnetThe alternate control channels on FleetNet are primary control channels on PSRN, in some cases. (Example, Toronto.)
Maybe Simcoe, too.
