[Elecraft] K2 Mic question

[Don Wilhelm]

Paul,

Do 2 things.
Yes, connect straight across the microphone configuration header to 
connect +5V to pin 6, and then solder a 5.6 k resistor between pins 1 
and 6 of the mic jack.

Second thing is just a check of the Heil Kenwood adapter - use your 
ohmmeter, connect one lead to pin 6 and check the resistance to all 
places you can plug something into - expect a very high resistance - 
maybe infinite (same reading as with the leads separated).

This last step is just a check.  Bob Heil has told me that only 4 
conductors are connected in his adapters, AF, AF Return, PTT, and PTT 
Return, but if someone else had it, there could be modifications.

73,
