[Elecraft] K3: Audio settings

[Jim Brown]

My uses are pretty similar to Josh's. As soon as they were available,I 
added the new synth boards, and the KXVB board to get the better preamp 
to my early (2008) K3s . Like Josh, I have several good USB audio 
interfaces, including a Tascam US100 and Numark Stereo I/O.
