Also, if you come accross any old freqs. for the Suffolk County Sherriff (inactive) THEY ARE NOT INACTIVE!! I have found that STPD uses the freqs. often.
From the looks of the FCC licenses looks like the usage of these frequencies was just moved to the east-end towns. This explains why 155.685 (SCPD Command) is still active, I mean aside from the various 800mhz dead spots.
