Craig,
The easy way is to obtain the KX3-PCKT cable set from Elecraft. That
will allow connection between the KX3 and a soundcard. For computer
control and frequency readout from the digital application, you can use
the KX3USB cable that was supplied with your KX3.
Yes, the Elecraft cable set has a cable for the RX I/Q and the ACC2
cable that are excess for your purposes, but the audio cables have right
angle plugs on the K3 end which keeps the cables out of the way. You
could just use a couple of regular audio cables with 3.5mm stereo plugs
instead.
If you find excessive noise on the audio between the soundcard and KX3,
you might have to add isolation transformers - that would be your
"interface unit". You can obtain suitable transformers from Radio Shack
and many other places. I have used the transformers salvaged from old
computer modem cards with success (see my website www.w3fpr.com).
I don't know the provisions you have on that computer for soundcard and
USB, but you will need line level input and output on the left channel
(tip) as a minimum. The right channel is not used for digital modes.
