OK, I'll ask due to I can not find any info on it. Has NSA security (police) changed frequencies and if so what are they? There has been nada on the old ones for a while.
There is a push Navy wide to change over to a new ELMR system in the 380 to 400mhz range. Look in the data base for other naval installations in FL (Whiting Field, Pensacola, Jacksonville) for thier freqs and that shuld give you a starting point for your search in that range.
