I live in harlan cnty ky and use a uniden bc785d digital scanner for state police frequencies. i use a grove scanner beam and can get a lot of london post which uses the same frequency of harlan post. if i turn the beam perfectly i can get 98% percent of londons traffic. but i really wish not to, however if i turn the beam or use other antennas i get the scratching and un-audible traffic. . i hope that their is a tone ctss or something that i can place in scanner and eliminate the london post.. does anyone know of a free or cheap software program i can use to find tone frequencies that simple to use. I have a uniden 895xlt but on digital freq ill need to be able to hear the signal to distinquish between harlan post or london. If thier is another way or if anyone already knows the tones i would greatly appreciate it. thanks andrew stoots
