I'm a public safety/9-1-1 dispatcher for two different agencies here in Passaic County. All 3 frequencies are correct for monitoring PCSD.
45.220 is still used for dispatching and general use.
866.675 is used for dispatching units in the southern and northern sections of the county
867.350 is used for dispatching units in the central section of the county.
All 3 frequencies are conventional, just use a PL of 114.8 for 45.220 and a PL of 203.5 for both the 800 MHz frequencies.
