Thanks Joe - Just what the doc ordered! I've got a dead Rascal that I can rob the audio lines from. Questons in-line.

This is the audio from the rig to the computer? Should that be Line IN? Pins 4 & 2 on what? The plug's nomenclature is tip, ring, then sleeve, right? > For PSK/AFSK add another 3.5mm audio cable to Line Out. Pin 1 > to tip and pin 2 to sleeve. > Audio from the sound card to the rig?
