Not to open up a dead thread...but...
I heard some P25 in the clear comms earlier today on 142.4100 - the St Catharines channel. It *might* have been Fleetnet, but it came in VERY strong here in Toronto. I don't know what the NAC was.
It sounded like techs working though, no police chatter at all - stuff like "okay Chuck, let's try that other one again" and "alright that sounds better, try it again". I'm guessing they were doing site work and either didn't have crypto, or weren't using it for some reason.
