Basically I'm relatively new to scanning and pretty much clueless. I bought a Pro-2055 Trunk Tracker scanner yesterday from Radio Shack. The conventional frequencies I don't really have a problem with, but as far as the Trunked talk groups, that's where my not having a clue comes in to play. I programmed in 867.125, and when I have it on MAN and put it in MOT mode most of the Talk groups I'm interested in come up and are Identified, but as far as listening to one particular talk group and blocking out others, how do I do that? And can I program in a talk group w/out the tower frequency? I still haven't been able to find the talk group for Cherokee County yet, but know the ID is 21520. Any help would be greatly appreciated. Also for some reason when I have it on Scan, for some reason it won't pick up transmissions over 867.125, but then I'll hit MAN and it will be in the middle of a transmission, not really sure why that's happening either.
