It's been a few years since I've lived in Hamilton, but I am open to others sharing information as things are always changing. Starting off with the basics, I know that according to the Bell FleetNet listing here on RadioReference, they have the following channels:
DEC | HEX | Mode | Alpha Tag | Description | Tag |
---|
35584 | 8b00 | A | Hamilton CACC | CACC | EMS Dispatch |
35600 | 8b10 | A | Ham City East | City East | EMS Dispatch |
35712 | 8b80 | A | Ham City West | City West | EMS Dispatch |
35616 | 8b20 | A | Ham Niagara N | Niagara North | EMS Dispatch |
35728 | 8b90 | A | Ham Niagara S | Niagara South | EMS Dispatch |
35632 | 8b30 | A | Simcoe Norfolk | Simcoe Norfolk | EMS Dispatch |
35648 | 8b40 | A | Hamilton TAC 1 | Tactical 1 | EMS-Tac |
35664 | 8b50 | A | Hamilton TAC 2 | Tactical 2 | EMS-Tac |
35680 | 8b60 | A | Hamilton TAC 3 | Tactical 3 | EMS-Tac |
35696 | 8b70 | A | Hamilton TAC 4 | Tactical 4 | EMS-Tac |
In the few years I lived in Hamilton, I never heard any traffic on the "City West" talkgroup. They seem to mainly sit on the "City East." As per their tactical (TAC) channels, I know that Hamilton has used "TAC 3" and "TAC 4" in the past. However, they seem to be pretty specific.
When an ambulance is dispatched on "City East," they respond to the call. Once the ambulance has arrived on location, they typically switch to "TAC 4" for the time that they are on scene. Once they depart the scene, they usually switch back to "City East" and return to their station (10-19)... unless there's another call for them to go on.
Now this is what I can't 100% remember. First up, I can't remember which talkgroup they usually patch to the hospitals on. However, during incident standbys, where they need to further separate the traffic other than having everyone on "TAC 4," I have heard them use "TAC 2" in the past. I am not sure that this is a standard for them though. These instances if I remember correctly are extremely rare.
I think the best bet would be to see if you can find a Standard Operating Procedure (SOP) for comms from the Ministry of Health, or more specifically Hamilton CACC. I am not sure that this information has been released to the public or not, but I am sure if you look hard enough you can find something out there.
