Filing Flight Plan
I have a helmet that was wired for ultralight (single plug). I bought an adapter to be able to use it in my experimental which has dual plugs, standard GA arrangements. I can hear fine but there must be some impedance mis-match with the mic because others cannot understand what I transmit. I carefully removed the casing on the adapter and see at least one resister. Anyone know any way to figure this out and perhaps swap out a resister or something to get this to work.
BTW my general aviation headset works fine in the experimental.
I used Jim Weir's circuit from kit planes, I think the mic works, the amplitude of the signal it generates seems to be way too low.
Strangely I am unable to find a circuit diagram for this adapter. Must be top secret...
