We have had a problem with the transceivers being exposed to moisture and causing the issues we have seen across the fleet. Last time I talked with the roa avionics guy he said the ground test is useless because you have to be in moisture to get the erratic cdi swings. They are working on fixing the fleet but unfortunately they don't get focused on unless they are written up.
