[Elecraft] Fw: homebrew KX3 electret microphone

[David Shoaf]

You don't need a TRRS plug.  You can use a TRS plug.  Mic hot lead to the
Tip.  PTT to the Ring.   Ground on the Sleeve.

Then, in the Menu, set MIC BTN = PTT.  This turns the Mic Button feature
off.

Mic bias is applied to the mic lead on the tip - no separate connection.  
See the schematic on the Elecraft website.
