Now there's a memory flogger... when I went to college there in the late '70s (I lived in Libertyville when not at college), the PD was on 155.655, same as the Lake County Sheriff's Highway Patrol and Libertyville PD, and FD was on 154.430, same as Libertyville FD. I didn't even have to acquire any new crystals for my 4-channel PRO-4A!
