Re: [Elecraft] MD2 microphone
Stephen, The pinout for the MD2 microphone is the same as the MH2 and MH4. Bias requirement is also the same - it needs a 5.6k resistor from the AF signal (pin 1) and either +5 or +8 volts. The pinout matches the mic jack wiring which is shown in the K3/K3S manual on page 13. Download the K3 manual if you don't have it. You may also find the microphone pinout at the G4WPW website which has been preserved at https://www.qsl.net/g4wpw/date.html#others. Hint: connect both pin 7 and pin 8 to the common ground. 73, Don W3FPR On 4/4/2019 4:11 PM, Stephen Prior wrote: 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.

John, Either will work. 73, Chas At 04:08 PM 1/22/2005, KI7V (John) wrote: Hello, I purchased a MD2 Microphone for my K2 a few weeks ago. I also have a footswitch that I'd like to plug into the Pig-tail but, I have to make a cable for it. Does anyone know if the pig tail requires a stereo (3 conductor) 1/4 in plug or a mono type?
