154.235 - 5 bases
453.2625 - 1 FX1
458.2625 - 5 FX2
I bet there is 1 base at each fire station - and each station uses a
different PL - and the 458.2625 freq is used to move the 154.235
traffic back to dispatch - and the only time there would be a possible
problem is if 2 people from different FDs key up at the same time -
then there will be radio waves colliding on 458.2625
