Jerry,
Then we'll probably have to agree to disagree :)

Not so!
If you calculated the power density you would expect to see at that
range from an isotropic radiator in Free Space - one which radiates
uniformly in all directions - then apply the predicted EZNEC dBi figure,
it should match the power density you measured.
As I see it, it's not a problem with EZNEC, it's how you define the
reference power density; and your definition seems to be out of step
with all the engineering references I can find.
