[Elecraft] KX3 - Pandapter woes

[Buck k4ia]

Yes, indeed.  One of the Chinese pig-tail adapters was shorting the two 
signals.

I changed adapters and gave the program some time to run and cancel out 
images and it works much better now.  I still have some recurring spurs 
that run up and down the band chasing the center frequency so there's 
work remaining to be done.
