Lacking any better information, I have been leaving TGs for merged departments as-is. I suspect each fire station has continued to use their "talk" TG for their own training activities.Those ID's belong to Irondequoit Fire and that training would also be correct. That TG was Laurelton and could be changed to Irondequoit as they were merged with Ridge Culver which also has TG1456 that could be changed, but I have no idea which would be the Primary of the two.
That TG for AMR was referring to where to park all the times I heard something on it.
