Hallo Cathy, for what it is worth I build a small audio interface from PSK31 based on the ideas from Don, W3FPR. You can find the result on www.qslnet.de/dk1htx.
My ambition was to fit the thing inside the K2/100 without taking up space required for options. I have to admit that it did cost me one or two evenings before I finally got it right.
