A friend has a RV-12 with Garmin GTR200 and dual Dynon HDX. Airplane is five-years old and has 500TT. The comm has developed a screech sound when transmitting. We hear the screech in both Zulu3 headsets. Makes no difference which PPT is used - still have same screech. It’s been reported that aircraft receiving our transmission also hear the screech. Radio was working well until recently.
Any ideas apprenticed….
