This is my first time using a digital scanner (TRX-1) and I'm trying to scan the central county 911 south channels (South Dispatch, South Main, Tac20-29). I have inputted everything into a scanlist and have heard very little. Every now and then I pick up the end/beginning of a transmission very clearly but the transmission cuts of. I know this for a fact because when I listen to a live feed I hear the unit continue to talk. I live in Wildwood just north of the intersection of hwy 109 and 100. I have put in the north, south and St. Charles site, as I'm kind of in the middle of all the sits and I am not sure which one the south channels use. Any help would be greatly appreciated!
