X-Plane 11.20
Windows 10 March 2018 Update
Pilot2ATC 2.5.0.3 x64

I know this is going to sound strange, but I have verified the problem is with Pilot2ATC and can reproduce the issue consistently.

1. Boot up any aircraft in X-Plane that is using the Laminar G1000 (e.g. the Cirrus Vision SF-50).
2. Use the scroll wheel or mouse click region on the COM radio frequency (they should work normally).
3. Start Pilot2ATC and connect to X-Plane.
4. Use the scroll wheel or mouse click region on the COM radio frequency.

After connecting with Pilot2ATC scrolling or clicking the COM1 dial will result in significantly jumpy/uneven increment/decrement behavior including the frequency incrementing or decrementing randomly in the wrong direction from the scroll/click direction. As soon as I disconnect Pilot2ATC, the COM1 frequency dial immediately begins to work correctly again.

Thanks for the detailed report.

I'll look into it.

Same issue not with G1000 but also on XP 11.21, Cessna Centurion with REP, Cessna Skyhawk with REP. Keeps messing with radio inputs, also transponder.

 

ALSO now at SAWE

Try changing your call sign.  Or use the full call sign like Beech Zero Zero Four Seven.  The program may be getting confused by all the numbers.  An abbreviated version of Beech N0047 would be Beech 047 or possibly just 047, but not 0047.
