I have been trying to get this issue sorted out with the saitek support team, but I'm not getting anywhere (the suggestions they offered aren't fixing the issue). I purchased a saitek radio last year. I used it along with a saitek yoke, pedals and cessna trim unit. The radio operated perfectly. I purchased the multi panel last month and added it to my sim experience. Suddenly, the XPDR section of the radio unit mysteriously went blank when I switched the button to it (that meant I could no longer manually set the transponders in my planes).
I've downloaded drivers, I've uninstalled and reinstalled my radio (it came with a CD)... I've even checked the overall health of my system's drivers, but nothing worked! In addition, the saitek panel test pages indicate that everything is fine with both units.
I am puzzled. It almost seems as though the 2 units were made by 2 entirely different companies!
