Okay, I was undecided where this should go, Software Support or RS Scanners and finally decided the problem was more software oriented than radio. In any case, it didn't belong in the General Scanning forum.
Now to the problem at hand, make sure that at the top of the software page for the bank you are programming that the pull-down says MOT. What you are describing (and I am making some wild guesses here) is that you need to program the Metro PD numbers from
Indianapolis/Marion County Public Safety, what you are seeing is that the software will not accept the large numbers, this is probably as a result of that pull-down either saying CONV or EDACS, both of which sets those TG fields to 4 digits max.
If this is the problem then you are good to go until the area goes P25 sometime next year.
