Those T-Tables are pretty much the standard ones that most systems use for P25. If you listen to a talkgroup and it trunks over to another frequency and you hear nothing, then you have the wrong T-Tables programmed in. Also if you have the wrong ones you probably will hear nothing. That is more or less the programming that tells the scanner or radios what frequency to go to when they unkey and rekey the mic. Also I know of one system that refuses to auto program the T-Tables on some scanners just in case you run into that problem.
