Thanks for the info. When listening to both Ft. Lauderdale FR and Pompano Beach FR, specifically, it sounds like the same dispatchers and the same tactical channel assignments (TAC-1 through TAC-4). Does BSO dispatch for FLFR and PBFR?
They have 3 dispatch centers: north, central, and south that divvy up the various jurisdictions that were gerrymandered under Ken Jenne and they are ever so slowly coming out of the Stone Age to embrace this newfangled concept of mutual aid. They conduct a roll call on tg 10020 "fire call" at 10:00 and I think 23:00 every day so you can hear who's who there.
Broward County fire has 15 tactical channels that are assigned in numerical sequence as incidents pile up. So they assign tac 1 to the current incident, tac 2 to the next one, tac 3 to the next one after that. These tac talkgroups are common to all participating agencies.
Special note that tac 11 is used by FLL ARFF so if there's an aircraft incident at the big airport that is the channel to monitor.
Fort Lauderdale has a similar block of talkgroups on their system, but they haven't used them for incident response for a few years now. It was something of a fire drill when they started on their tac B, then when the incident grew to the point that they needed mutual aid they had to switch units over to the County talkgroups anyway so they just got smart and start there nowadays.
The trouble is that there don't seem to be any standards at Broward Fire dispatch, so often times the Info channel operator will hand out fireground talkgroups for training drills, which is really bad form. They have 3 training talkgroups labeled for that purpose that sometimes get used.
