Chris,
A good quality external soundcard will do much better than the SignaLink
(the Signalink noise floor is poor and is only a single audio channel).
The K3 has galvanic isolation (transformers) built into the Line In and
Line Out lines.
Jim Brown K9YC has recommended a Tascam soundcard as a good and
relatively inexpensive one. You might also want to read Jim's
information on bonding equipment.

external interface for digital modes? I had a SignalLink USB at one point
and it worked quite well.
