Hi Dave,
first i want to let you know that i´am very happy about your ATC. I can´t fly without it. I´am even more happy about the ongoing development and the new update, but since the new update i have a small issue.
It happens to me, that the Transponder code gets deleted somehow after lift off while takeoff. After clearance i´ve set the TP code and it´s set till i lift off. Then out of a sudden i´ll get the message by departure "check transponder your squak should be..." and i can see in the remote radiostack that the TP is "corrupted" somehow. If i try to correct the TP with the mouse in the stack i got an exception warning message about a dll an the stack is closing. After reopening i can correct the TP only via my MCE-FO to tell him "Set TP to xyz" and than it works again. Could it be the Remote Radio Stack itself, because i havn´t change the app after the update of PF3?
I use the Remote radio on a network PC only for troubleshooting because i have a homecockpit where the TP is set via hardware which sets the changes of TP in P3D. I also have MCE in use, but no issues so far. The FO can set the COM radios for example without problems and even the TP in case i order him to do so.
