The wind storms tonight apparently caused a fire with a transformer on a utility pole downtown, and I just heard fire unit "Brush"-something come up on TG 30223 and explicitly state his callsign and that he was "on Tac 5"... do you happen to recall how you determined that 30225 was supposedly Tac 5?
30223 actually follows the pattern of odd-numbered TGs for those tac channels, if 30219 is Tac 3, and 30221 is Tac 4, then 30223 is logically Tac 5.
(And one could also deduce that 30217 is Tac 2 and 30215 is Tac 1)
