Two main ones for the aircraft: 322.9 is the Command Post freq and 292.0 is the A/A freq for the C-130's when they go out as a two ship.
And your location at the top is waaay to broad but if you live near the airport then also try these:
163.4625
163.4875
163.5125
165.0125
165.1125
These are all used by the ground crews. Also try 173.4125 which is the Security Police (quite active).
