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.
