Could be anywhere in the 380-390 MHz range using 12.5 kHz spacing. Search for the control channel. Last I saw they where using a P25 Phase I 400 MHz system. Is that one not active now? See https://www.radioreference.com/apps/db/?sid=6447
Is this because nothing is being transmitted over the system or you're hearing nothing because all transmissions are encrypted and you have your scanner set to mute encrypted transmissions so you don't hear the annoying digital noise?
