Hi Clay,

It's worth downloading WSJT-X, installing it, RTFM, and then start 
listening. It's excellent software, well written, well documented. And, 
if you RTFM, easy to use. Among other things, that will get your ears 
tuned in to what those modes sound like -- just set your Mon gain so you 
hear what you're TXing, and you'll know.

Hookup to K3/K3S is super easy. feed the Line In from Computer Out, Feed 
Computer in from Line Out, set the K3/K3S for Digital A and VOX. in 
WSJT-X, push Tune to get the computer to send a steady tone, set Line In 
Gain and VOX Gain so that you go into TX, adjust Line In Gain so that 
ALC flickers 4-5 bars. Adjust output from rig to Computer so that you 
get indicated 30-40 dB on the WSJT-X bar graph.

Choose FT8, select the band you want to try first, and you should see 
decodes every 15 seconds.  Also, WSJT modes require a clock within about 
1 sec, do whatever is needed to accomplish that. I use this one.
