[Elecraft] KX3: Cleaner audio with Yamaha CM500, also PTT

[Don Wilhelm]

wunder,

After building an adapter using a TRRS plug for myself, I had a 
"head-slapping" reaction to your solution.  It should work wonders for 
not only the CM500, but also for most any other microphone designed to 
be used on a computer - most, if not all, have the tip and ring 
connected together.
