For your area I would have scanlists for:
DPS, MCSO, PPD, Feds (BP, DEA, FBI, etc.), Scottsdale, Peoria, Surprise, Phoenix Fire, Rural Metro Fire, State Land Fire, and Glendale PD to start with. Glendale (unknown site location),and Surprise which works on the WEST Maricopa County system, might be hard to get, but there is only one way to find out.
