If you want to hear any law enforcement and fire department in your county and city, you will need an analog trunk tracking scanner. The 350A and 355N will not work. You'll need a BC15X. It is a little more expensive, but will work on the county frequencies.Found a Uniden BC350A and a BC355N for the same price but don't know much about these scanners and this will be my first one I've purchased so any information that can help me make a decision is appreciated! Thanks!
