As was also suggested before, running scope.py without the -T argument on the control channel will show the NAC using no additinal hardware than what you already have, including no reason whatsoever to use a separate Windows computer.

Dick,
I was going to suggest that your try setting the NAC in trunk.tsv to 0xF7E that is a universal NAC that works to decode any P25 system when programmed in a Motorola P25 radio but I tried it with scope.py and got no system audio until I put the correct NAC back in my trunk.tsv. So I am thinking that your remaining issue is likely that you have the wrong NAC and should try to follow my suggestions to obtain it from my previous post.
