Edit: I take it back. It appears to be plane related. The ATSimulations Piaggio FWP.149 doesn’t allow the radios to be autotuned. I’m imagining this has something to do with it.
Thing is, Center Control ATC used to work fine with it. I’d tune the correct squawk code, and ATC would respond back. But, for whatever reason, their radios break ATC now.
I’m going to have a look at it. maybe I can figure out what’s going on since the developers are dragging their feet fixing this.
