My dad used to have a scanner in his truck in the 80's, and we would be able to listen to all type of things like cops and train conductors and things like that. I'm wondering if a scanner would be a good idea so we could know in advance if someone called the cops on us. Would old scanners work now, or do cops use something that civilians can't get the frequency of?
I know my dad's old radar detector doesn't work now. I could drive right by a cop and the damn thing never goes off. I'm thinking I'd have to get a new scanner too.
