All the years I have been on top band, I can't recall ever hearing or
working him - DXing on Contesting. With all his hardware on 160, surely
sometime his presence would be evident other than the reflector... Anyone
else?
Merry Christmas to all.

AMEN Tom, He Just is like the "Energizer Bunny". He keeps going on and on
and
on.

Or the person on here who went from an extensive radial system to a full
screen
claimed a 5dB improvement but now denys the possibility. Its in the TB
archives
from 1998.
Carl,
Please try to stop that silly disappointing long-time practice of
re-writing
what other people say just to start a fight.
I ****NEVER**** said I didn't measure a 5 dB change, or that some system
changes
can't produce a 5 dB (or even a 30 dB) change when someone does something
terribly wrong in a system. What I am saying is:
1.) Your claim you felt you had a ~10 dB change, based on your feelings of
how
much a signal must change busting a pileup, when you added some screen to
a
system is pretty silly. It is a test at least days apart on sky wave with
no
data reference at all. It is typical junk science of the worse kind. If
your
original ground system did not have severe issues, the imagined "10 dB"
would be
impossible.
2.) Broadcast stations use a screen as a connection point and mechanical
convenience, NOT to improve signal or effiency. The screen allows people
to walk
near the tower base without falling over wires, and it allows connecting
boxes,
fences, posts, and other things into the radials no matter where they are
located near the base. They also usually use stone at the base, and
weedkiller...so we can't assume everything they do is for "signal
reasons".
If you take some time to read FCC guidelines, the screen is actually
optional.
If you read Lewis, Brown, and Epstein, instead of misreading Topband
archives,
you will see they ALSO said the screen does not when a adequate number and
length of radials is present.
Please stop the silly childish misrepresentations.
73 Tom
