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, Don W3FPR On 1/1/2012 3:46 PM, Paul W.
