I live in St. Clair County, MI which boarders the St. Clair River, right across the river. I have Sarnia's PD Freq.’s listed as APCO 142 MHz... I have a PRO96 so I'm thinking that would work, right? Well, I don't know if they're the correct frequencies because I have heard no traffic on them. If anyone has the correct freq. or tells me what I am doing wrong... thanks.
