[Elecraft] RTTY using DATA mode on K3

[Bill VanAlstyne W5WVO]

Hi Derek,

When using a computer and sound card to drive the K3 in any digital mode, 
your data mode should be set to DATA A. Somebody will correct me if I'm 
wrong, but I suspect that's your problem.

DATA A mode is basically equivalent to the USB/LSB position, except that 
equalization and compression are disabled.
