I have heard action on 154.445 and 141.345
I can confirm that 141.345 is P25 with a NAC of 473 and they were using TG 1

Are they dispatched out on 1 frequency and then switch over to a tac? Or you hear the dispatched audio and them responding same channel
Kinda like how london pages on alerting and then gives them a tac.
4 Repeaters for st thomas so not sure how they do paging at all if its just station alerting or actual pagers
can confirm now that 154.445 is p25 with a NAC of 392 and also TG 1
I did not hear anything on 149.245, so if this is in use could be an input
from what i have heard so far I think they are on 154.445 and then change to 141.345
they are refering to 141.345 as repeater 1

Interesting that fire is P25 and Police is still DMR. I wonder if Police will be switching to P25 as well? Also makes me wonder if they are building out a P25 conventional system for the city. You'd think police would be P25 first and then fire would follow suit
I'd hazard a guess the money for all this is related to the new battery plant being built. With all the construction and upgrades happening just because of that place, this kind of falls in line. And yes will be interesting to see what police do.

St Thomas Police are DMR with AES encryption and also dispatch out Aylmer Police. Maybe they are good with what they have at the moment but who knows?
Sarnia did similar. Bunch of conventional repeaters around the city for police, fire was DMR then went P25 AES and added their own repeaters to the same locations police have theirs. Why not have a trunking system rather then having 34 repeaters over 6 sites..
So then paged/accept the call on 154.445 and then jump in the trucks and respond on 141.345?

Elgin county fire is DMR also, would be a interop problem
Patching between the systems shouldn't be an issue these days. Not as easy mind you, but still doable.
What you are hearing tonight is probably from the States. Band conditions are up tonight.
I also have been monitoring that system on 154.445 with a NAC 5D1 , I have seen a least 3 different talk groups 10410, 10413 and 10459.
Talk group 10410 is running AES with a KeyID 2062

When I check the NAC 5D1, it tells me you are receiving the Canadian Armed Forces. Those three talkgroups are from Base Borden Public Safety category. You may have found a new frequency.

That matches the talk group10410 that was encrypted, which was the Military Police.
Nice catch 😊😊😊

I forget how it works but under the right atmospheric conditions it's absolutely incredible how some very far away signals come in. I remember being in the west end of Mississauga and getting Kawartha Lakes Fire, so you probably had one of those nights last night hearing the Base Borden system down in St Thomas.

For me in Chatham-Kent, it seems I get ALOT of stuff from Michigan Public Safety and Ohio on the good band condition nights. Sometimes I can pull in London's P25 system and some NXDN sites all the way out to Goderich.
Only once has it been so good I was picking up Kitchener's P25 system.
Reception improves once the sun goes down, something about a protective layer of the atmosphere goes away or some magical thing like that and makes radio signals go further.
If your by a large body of water they skip across that water and go further also.
Mysteries of the world. I've got St.Thomas Fire in my scan list on record for the past week.. I should really check that and see if I got any hits on it or not. Not very often I pick up stuff from that neck of the woods, it always seems to be from the southwestern area.

This map kinda shows what's going on.

I'll throw 154.445MHz into something here but as of last week, it wasn't a frequency on the Borden system.
Looks like the input to 154.445MHz is 148.960MHz which is an output of one of the Borden trunk system repeaters. Someone must have left the St Thomas Fire repeater input wide open and when conditions are right, it rebroadcasts Borden.
Whoops.
Whoops.
