Richard, Richard, Richard. Clark, that is. Shame on you. Get a grip.
Richard Fry's list simply showed that in the FCC listing, the length
in degrees is calculated on the basis of freespace speed of light. In
addition, he was pointing out that resonance is not at 90 degrees,
calculated in that manner. THAT point is supported by other data. The
FCC data didn't come into play with respect to that point. All that
was obvious to me.

Do you disagree that resonance of a monopole over a ground plane is for
a length somewhat shorter than c/(4*f(resonance))? If you do, then
let's have a discussion about THAT.

Cheers,
Tom
