[Elecraft] what connection to computer soundcard & Ham Radio Deluxe works well with K3?

[Don Wilhelm]

May I suggest Line Out from the computer (instead of speaker output) to 
the K3 Line In.
Also Line out from the K3 to Line In on the PC.
The levels between speaker out and mic levels are just too great and 
need an attenuator to allow the levels to be set properly.  Line levels 
are more "mild"

Yes, only 2 cables are required - the K3 has transformers on the Line in 
and Line out signals that provide galvanic isolation - no extra 
interface needed.
