[Elecraft] K3S audio quality issue

[Bill Frantz]

Swapping side bands can happen behind your back. I was part of a 
multi-multi activating Kings County in the California QSO Party. 
My assignment was 10M SSB. The first contact suggested I would 
be more successful if I switched from LSB to USB. I have no idea 
how I swapped the sideband. I guess holding the wrong button. Or 
maybe I held ALT instead of pressing MODE-DOWN.
