Stan,
Looking at your KX1's 20m Tx spectrum shown in your picture, my impression
is that the wide pedestal in the bottom part could be due to phase noise. I
will return to this later. However as I do not own a P3, which I think you
are using, I am not familiar with how signals "look" on the P3 and whether
or not some characteristic of the P3 is contributing to the wide pedestal.
Does your KX1's Tx spectrum look "narrower" on the other bands?
73,
