Incase anyone is curious - there's nothing wrong with your radio. TFS has stopped voicing their dispatches over the Dispatch talkgroups. It is done via automated dispatch over an IP system, just the same as Toronto Paramedic Services. The only time now you'll hear a dispatch over the air is for an "on the air" call, where one of the dispatched trucks is out of station. This will happen on the Operations channel for their respective command.
