some things to check
I have just returned from a few days away in Italy with my xyl. Being
limited with what we could take (we were flying, usually we drive), I took
along my KX-1. It was the first time that I had used it this year- blame
the K3 for that!
When I used it last (in CT and EA in summer 2008) I posted
...three or four strong broadcast stations around 14.2MHz
Harmonics of 40 meter BC stations..?

Hi Dick
Maybe they are, but I don't hear anything on the K3 (or even my FT-817) on a
much bigger antenna, and anyway there is not much BC activity I can hear on
7.1MHz these days. I should add that the KX-1 has the 30/40 board and the
internal ATU fitted.

Hi Stephen,
The KX1, like most low-current QRP transceivers, uses an active mixer
in the front end. IMD products can appear in the mixer's output
spectra when large signals are present at the input, especially if the
LO (local oscillator) injection is insufficient.
Try backing down the RF
Stephen,
The first thing I would suggest is to see if the KX1 is really receiving
on 20 meters, or perhaps on some other frequency band. What I am
thinking is that the firmware chip may not be fully seated in the
socket, which will cause to DDS output to be on some unknown frequency.

Many thanks Don, I have also had some input from Wayne on this one and have
some things to check with the scope. I shall combine your reply with his
and see where it takes me.
Thanks again
