[Elecraft] KX3 PC Headset Stereo mike

[dombaines at yahoo.com]

HI,

KX3, I have played about with the two mike settings BIAS (on/off) and 
pgupdwn/ptt/off with a computer headset where the 3.5mm mike has a 
stereo plug and no joy. Noted it initially as got the PTT error message 
and TX stays open when plugged in. No amount of combinations of with VOX 
on/off and setting the mike options seems to make it work where pressing 
the PTT on the KX3 keys the mike (or VOX does).

A stereo to mono adapter doesn't seem to help.

Anyone had a similar problem and got a cure?

The headset is identical to another I have as I wanted to get a second 
set (for second KX3) but the earlier one has a mono mike.

I looked at chopping the cable and rewiring (The mike has a tiny + screw 
in it so I undid it just to see how it was wired) but I noted the wires 
are not the easy to solder type.
