[Elecraft] MD2 microphone

[Stephen Prior]

I don't know whether anyone can help, but I am trying without any success
to get the MD2 microphone working with a SunSdr2 transceiver, which is able
to provide the necessary bias voltage I believe.  What I am lacking, and
have not been able to find online is the original manual for the microphone
giving pinout and bias details - for I'm sure that there is something that
I must have missed.

Thanks and 73,
