[Elecraft] K3 and Digirig - Any hints and tips on the K3 settings?

[Dave]

You do not need Digirig with a K3... All you need are cables from the line
IN/OUT on your K3 to your PC sound card line IN/OUT. Use the line in
settings for DATA with the K3.

I ran a K3 for several years on data (FLdigi, WSJT-X, etc) and never felt
the need to buy an interface, I have no idea what Digirig is supposed to
offer as the K3 already has built in line transformers for that very
purpose.
