[Elecraft] Setting the audio level for use in soundcard data modes.

Tom,

Using DATA A is the same as using USB *except* compression is set to 
zero and TX EQ is set to flat automatically.

So yes, USB may work OK, but you have a lot more flexibility with other 
modes when using DATA A.

That allows you to set whatever you want for SSB and not have to change 
it when you want to operate digital - which should not use compression 
nor equalization to minimize distortion in the transmitted signal.
