with Terra radios and most USA types you can use Carbon, Electret (Aviation
type) or amplified Dynamic microphones....
you can also add amplifiers (I have these) to most European type Boom *Mics
(typically dynamic)
confusing thing ad what throws some off is common microphones like Telex
Hand Mics will say they are Dynamic right on the mic, and they are, but they
are also "amplified" .If you get confuse or need advise, don't hesitate to
call me

I have the wiring diagram and I am trying to repair this for a friend.
Does anyone know if the microphone used with this radio is a dynamic
or electret type? I am building a troubleshoot setup on the bench to
simulate the sailplane wiring.
