Hello, I do not understand what T-Tables first of do for your scanner but I would like to program it in on my MOSWIN system that I am already monitoring on my Radio Shack 651. I live around the Columbia Area and have programmed in the Columbia 700 frequencies and Ashland's frequencies and some other sites to if that will help you tell me how to program in my T-Tables for my system. If any one has any information about what I am talking about and how to do it please reply. Thanks, Tyler.
