ok, im totally new to all this. i bought a PRO 97 scanner off ebay & im trying to get this set up to listen to the local police agency so i can hear of things going on in my area. well, i was reading around & bought the data cable & i purchased the WIN97, since i heard it made things easier. but i really still dont know what im doing. i was trying to enter in frequencies, but some said invalid. i used the list of numbers from the search on this site. can someone point me in the right direction since im totally lost. thanks.
