[Elecraft] PSK31 with a KX2

[Bob Liesen]

All,
  Pulling my hair out here.  I have been trying to get my KX2 to work on
PSK31.  After many attempts I got it working perfectly with DigiPan, but
I'm not sure how.   Then something happened that I have found is a problem
for me with this radio.  I must have turned a knob, hit a key or some such
thing as it stopped decoding.  I find the knobs and buttons are too close
to one another for these old eyes and fingers.
  I am using DATA A mode, I have the BW at 4kHz and center freq of 1.5  AGC
is off, RF gain is 0dB.  NB and NR is off.  I suspected I might have
screwed up the USB/LSB setting somehow, but HamScope has a "reverse"
function which does not help.
 Is there anyone who could walk me through the settings that might be
screwing this up?
Tnx es 73
