Can you seriously believe that the ionosphere is non-linear, to the 
extent of 3dB in 20dB?

Not picking on Rich in particular, but it amazes me how many hams lack 
the ability to look at their own measurements and to say to themselves, 
"Aw, come on, that can't possibly be right..."

This lesson was hammered into me from age 11, in countless lab 
experiments to "verify" Ohm's Law, Kirchhoff's Law, Boyle's Law, 
Charles' Law, the Law of Mass Action - or whatever:

"If your results don't agree with Messrs Ohm, Kirchhoff, Boyle et al, 
then you can safely assume that the problem is all yours. Now go away 
and do it again, sonny."

With my lousy lab technique, it didn't take long to build up a healthy 
respect for those Old Dead Guys, and for the solid interlocking 
framework of  "natural laws" that they discovered... and a healthy 
caution about my own measurements.
