I am a newbie with scanners and just bought a radio shack pro 106. I guess I am a little too simple minded but I would like to know how to download the frequencies I want to listen to. Example: I downloaded the local frequencies on my scanner but I also have every city service along with the police,fire and emergency services. I really am not interested in hearing the trash trucks or dog catchers but I don't know how to eliminate the ones I don't want. Any help is appreciated
