[Elecraft] K3 sidetone volume Request

[Paul Christensen]

> For CW mode: The mon level is the default. It simply controls the sidetone
volume and can be adjusted while sending (no steady tone).

Good idea.  I've also become accustomed to CW side-tone that tracks with the 
AF volume control.  In doing so, the MON control still sets the side-tone to 
Rx audio mix ratio.  Perhaps another option one day...
