Okay, so this really is not a joke.  Perhaps I am not equal to
understanding that the radius of Earth is some kind of mystery or that it
changes from contest to contest?

This has really piqued my curiosity.  Until now I assumed this dimension
was for all intents and purposes, a constant.

Perhaps there is disagreement because Earth is, in fact, not spherical, and
the distance to the center is different depending on where on the Earth you
are.

I don't mean to go way out in right field here.  Maybe I'll just quit while
I am ahead (behind?).  Sorry.  This topic is probably better discussed on
the Boring Amateur Radio Club reflector anyway.
