I live in Portland Maine, cumberland county in southern part of the state. I would like to listen to all local activity fire,pd ect also interested in marine,air,and railroad. Actually would like to hear all activity I could get state wide if possible. New to scanning and I picked up this Pro 97 for $80 but is hard to understand the instruction book. Is this a decent scanner for what I want to do, and can I pick up frequencies in the northern part of the state? I had the local Radioshack program some frequencies but would like to program some more. There are about 60 channels in it now. Any help would be great. Thanks
