David, I use my KX3 to run WSPR, JT65, and JT9, using DATA-A. It does take a bit of trial and error, but once you find the “golden settings” between the KX3 and your sound card, things will be fine. I use a Tascam US-125M sound card; its output controls are set to about the 1:00 mark. With them like that, the KX3 gives me 4-5 bars of alc indication when set to about number 9.
Keep trying and you’ll get it going!
