Since most of the RT Systems cables are pretty much proprietary, I would try a basic cable and see what happens. That is about the only thing you haven't tried.

I know I have the correct com port, that is, device manager matches the one used in radio preferences.? Also the cable I've been using works fine for radio programing, so I know the cable is good.? I even purchased the software from RT Systems, a lot more user-friendly than the Icom s/w.

> edit:? Previous sentence, DRATS works fine with my ICOM 92AD on SIMPLEX, turns out it does not work through our local DSTAR repeater (2m).? After doing many factory resets, making tiny changes in the radio programming, still having problems with the 92. What was found, some operator's radios signals (voice or data) will make it through the repeater but not everybody's radios will make it to my 92.? I'm afraid I've been barking up the wrong tree here, now believing the problem has to be with the other user's radio, in this case an Icom 2820.? It's as though like analog, if the 2820 transmitted with a PL code and the repeater passed it, and thus the 92 opens up, vs, a 2820 not encoding the output with a pl code and thus the 92 not picking up the data.

> I know DSTAR does not use PL codes (analog or digital), so what could be missing in the 2820 programming?? I know this is more of a DSTAR issue, not a D-RATS issue but by using D-RATS is how the problem was identified.? Just need the fix.??? -? Jim k6nra
