Note: some of the VHF tone info may be old
The correct PL for The Illinois State Police on 155.4750 and 155.4600 Mhz (Illinois State Police Emergency Radio Network) ans (HF-4) is 110.9, as verified by the ISP FOIA officer with the below list. You have 156.7, so scanners programmed from your database (like my Uniden Home Patrol) do not open up as they are expecting a 156.7 PL, which is not used by the Illinois State Police.
