Dear IPACS,
The notes for latest Update Version 2.0.1EA3.36 mentions "Fixed transponder code can be set with Saitek Radio Panel and buttons/keys".
I tried this out but it doesn't work in my case, I can display the XPDER code on my radio panel, but cannot set it.
There's also a bug with Radio Panel COM1 Standby Switch Button, that switches both COM1 and COM2 sby frequencies.
In the settings panel they work properly, but not once in the aircraft.
Best regards and keep up the good work.
Cheers
Antoine
