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.
