Peter, VK4JD, wrote to suggest it was the stereo effects control, which
was set to delay. I changed it to Off and voila!
Although I plan to get parts for an audio isolator anyway.
Thanks Peter!
Thanks Don!

John,
Are you using isolation transformers (galvanic isolators) between the
KX3 and the sound card?
That may help. The alternative to galvanic isolators is to tie the
grounds of both the KX3 and the computer together with heavy wire (or
copper braid) Be certain that the power supply to the KX3 is included
in this bonding - the bonding should be from each device to a single
point ground.
Yes, I know that laptops with plastic cases are difficult to find a
good place to connect the bonding strap - in that case, the galvanic
isolation is the easiest solution.

I am using DigiPan to play PSK31 with my KX3. In the DigiPan
waterfall, it looks as though someone has dragged a comb through it,
with trace alternating with dark space showing no signal. I went
through the menu changes I had made, and when I toggle between Dual
RX Off and Auto, the PSK display changes. I have posted a picture
http://www.kk1x.net/photos/psk.jpg for those interested.
I'm curious to know why this is - now that I know why it happens, I'm
pleased, but I wonder if anybody on the list could explain it to me.
Thanks & 72,
