Hi Darren, and everyone else following this...
I've found it! Very low level, but by zeroing in on 385 to 386MHz I found a
small signal that moves when I tune across 7MHz...
At 7.000MHz there's a signal at 385.027MHz (-78dBm) which moves up in
frequency, staying at about the same signal level, and is at -78dBm at
385.571MHz with the dial set to 7.010MHz. Unplugging all of the leads
appears to make no difference to the signal level. Nor does turning off the
backlight or going onto internal batteries.
The problem I had yesterday was that there's a lot of much louder signals
around 385.9MHz which were masking the KX3 signal. With the dial set to
7.080MHz, and really zeroing in so as to exclude other signals, I found it
at 389.419MHz (-75.5dBm) but I would need to go somewhere that excluded the
larger external signals to hear it with another receiver.
I guess that with an antenna with a bit more gain it might be stronger. I
also had to keep resetting the display as it got hidden in much louder
signals which did not appear to alter with VFO setting and I wasn't able to
tell if they were from the KX3 or from external signals, of course.

Hi Dave,
I've have just repeated my measurements of the 7.080Mhz sprog on 398.4MHz
and
posted some screen-shots on my blog. See here:
