I have a GTN 650 and GTR200 working through a PMA450 audio panel. Indvidual bent whip antennas on belly.
When I transmit from front cockpit on either radio, air or ground, transmission is weak and muffled. Have tried 3 headsets, all the same.
From the rear cockpit all is normal.
My reasoning is since it all works from the back as advertised that I must have an issue with the front mic jack or another ground issue up front.
PMA doesn?t have individual output controls. Works great frm rear cockpit.
I?m going to pull the audio panel and check the mic jack barrells for good grounding. If that?s good, what?s next.
Where else should I check?
