Hello again, Mike.  As sometimes happens, not all the mail arrives in
chronological order.  Now that I've seen the message you forwarded from
WA6QPL, some additional thoughts arise.

After one wades through the questionable epistemology that even Emanuel Kant
would reject as too much uncertitude for living in the real world, and the
palaver about "not only don't I trust theory, I don't even believe empirical
results unless I did 'em myself," it seems he is challenging conventional
wisdom based on one point only:

Well, good luck!  Seven to 10 feet in diameter?  Feel free to give it a try,
as I doubt anyone else has.  I, for one, sure haven't ever had the resources
to try anything that dramatic!  :-)
