No, he won CW Sweepstakes operating from KP4. 1994 or 1995, I think.
Chip also had the use of a full sized antennas for 40 and 80.
Quite a feat, but not exactly a dx contest....

I stand corrected, it was a SS contest but I made my point how well small
antennas can work. I've been typing with a bad head cold and it affects my
memory--that's a good excuse. I have another example on 160M I did. I used
a 40M horizontally oriented quad loop 20' off the ground fed with a 1/2 wave
of open wire line. I have a sneaky way to load it on all of 80/75M also with
no big tuner. It's a folded 1/2 wave on this band voltage fed and is still a
broadside pattern bouncing off the ground for gain up, up and away. A great
antenna. On 160M the wire path from inside the shack from one wire to the
other was 1/2 wave now. With the Hi-voltage areas parallel to each other for
1/8 wave. If I could match the Z at the end of the balanced feed line I'd
have the center 1/4 wave section of the Hi-Current Area--doing it's thing.
At about 7 PM in the summer evening running 35W low level 160M AM, I was
working a station about 30 miles away. I got a better report than a station
running a Collins KW-1 of full high level modulation using a L antenna about
the same distance away. His angle of radiation was certainly not
optimum--mine was. He doesn't like to talk about that as he had 15 dB on me
and better audio. I have a KW-1 here but was unable to get it on the air real
I recommended hams do research on the CFA to smoke out all I could on it. I
got replies and one just today that gives good info. Some BC Engineers
actually went to Egypt and weren't permitted to use FS meters on the site but
did elsewhere and it was a bit weaker than it should have been. That's good
reserach. I'm surprised that they were allowed to inspect the CFA if it
wasn't a good antenna. That's kind of dumb. I gave them more intellectual
credit. It has to work better to sell--the main goal. The investors won't
allow it. You can't sell a total hoax--very long to the BC Inustry although
I've seen some go on to the hams for over 30 years. There isn't anything in
these 2 antennas that the designers could do more wrong for the tight budget
hams. I'd still like to try it and another variation of it. We shall see.
I've alerted the CFA detectives on TT and see what the latest AntenneX has
they will admit to. I'll be tough and threaten to cancel my sub.
I'm going on 160M tonight and see who I can embarrass with 35W with 1/4 wave
of very smart and Hi-Current RF wire. I will put it in Eznec also. With
this cold I have, 12 hours a day on the computer answering E-mails is not a
good idea which I admit. But these antenna issues are important.
