[Elecraft] Need Pinout for Heil HMM "icom" hand mic

[David Yarnes]

Rick,

Your K2 Manual shows all the pinouts, and it describes how to jumper the 
various pins if needed.  You just need to look at the pinout for the mike 
you have, and jumper accordingly.  You may have to solder some of the 
jumpers if they are not directly across.  Otherwise, just use the pins 
jumpers provided.  If your microphone is an electret, you will need to put a 
jumper between the V+ pin (pin 6 I think), and whichever pin is your 
microphone pin.  It's all described there.
