[Elecraft] KX3 Unwanted Scanning

[David Inger]

I decided to get my new (to me) KX3 going on psk31.  I ordered the proper
cables from Elecraft. Plugged the cables into the KX3 ("red" cable go to the
Phones jack; "green" cable goes to the Mic jack).  Put the radio in data
mode  ("PSK D" selected).  The radio begins to scan, and will not stop until
I unplug the green cable going to the Mic jack).  I tried this set up with
two different external soundcards and well as the one internal to the Sony
laptop; no joy.  I also tried different digital software programs to see if
that was the problem; still no joy.
 
I checked the archives and did find a mention to this problem in 2015 but no
definitive answer.  I am sure I am overlooking the obviously.  I will be
happy to put on my dunce cap, once someone can point me in the right
direction.
