I am not 100 percent sure if tcc is one the system wide agencies. So unless there are in range of one the assigned tcc towers. I do know that they have push to talk radios. aka old southern lincs would not surprise me if they had first net now. i left the ems game a couple years before tcc was born. In the old ages the state had ems regions. There are only 3 level one adult trauma centers in alabama mobile, huntsville , and birmingham. its very unlikely your going to hear a ground agency transport a full trauma pt from mobile or huntsville to birmingham. i only listen to the jefferson county system so i dont know about other sites . i have heard out of the per say birmingham metro area on tcc tac channels . the one that comes to mind was lifeguard amb out of hartselle . maybe morgan can give us some insight on this .
