Martin, I know you want to resolve any possible problem before January, but 
I notice we are both going to be at the campout 
(http://www.wa3wsj.com/MOC2007.html) in NW NJ. I will be bringing a 
Hewlett-Packard HP-8563A spectrum analyzer like the one here: 
http://www.ae5x.com/kx1.html and some other stuff as well, if any of the 
attendees are interested. We can make plots of our rigs, measure MDS, etc.

In the meantime, I'd resist making any "corrections" to your KX1 based on 
the methods you are using to test it  ;-)

73 and see you in January,
