[Elecraft] K3 - sound in problem

[Bob]

You might view it as two different routes to a solution, but the real
reason is to have a working solution for SSB (via Mic) AND a different one
for Data.  The Data selection disables equalization and compression for you
so you don't have to remember to do it manually.

I am constantly changing modes from CW to SSB to DATA, so having the
appropriate levels/gains/presets for each is a real convenience.

Hope you get things going soon!
