I remember my first scanner in the 70's, was from radio shack and what ever frequency you wanted to listen to you would buy a crystle and plug it in a slot. My grandmother turned me onto monitoring the local police and fire departments. She listened to them on a tunable transistor radio that had police band on it.The good ole days are gone forever unfortunately.
So the departments I want to listen to are difinately encrypted? It's just not a simple thing like programming error on my part?
