[Elecraft] K3 compression settings

[Joe Planisky]

Dave,

According to the manual (pg 31, "Data Mode Selection"):

"If you prefer to use LSB or USB, you'll need to manually set CMP to 0  
to prevent data signal distortion."

I believe if you use DATA mode instead of USB/LSB, compression is  
automatically disabled.
