I think that when one considers the Noise floor, and the sensitivity of
the three, those with a low noise location will notice the difference.

Another specification I considered was ultimate filter rejection.  After
having experienced filter blow-by, it is one of my top considerations.

I can't say that I have a superior location nor antenna setup, but I
routinely hear net control stations saying that someone just faded away
when I don't observe that kind of QSB here with the K3.  As I hear such
comments from NCSs in Kansas and Nebraska, it seems to be more than just
one operator making such comments.  I can't imagine the ionosphere is
more stable to this location than everywhere else.
