Aviators,
I need serious help please. On Saturday, my GTN650 + SL30 + PMA9000EX setup (I installed myself from Stein Air supplied harnesses and equipment) started acting up, out of the blue, after 150hours of perfect operation.
On transmission, I suddenly started getting a terrible loud feedback whine on any of the 2 radios GTN650 or SL30 (Zulu headsets)
I spend the whole of Saturday and Sunday, frustrating trying to trace the problem and fiddling with the settings, checking wiring / earths, swapping headsets, to no avail, so I am staggering in the dark.
Does anybody have some guidance on root cause for feedback whine on transmission and where to pinpoint the search?
It is so bad that fellow radio users and tower complain back to me about it. Never mind the ring in my ears...
Thank you in advance.
Kind Regards
Rudi
