A double bazooka at the distance you describe would have a massive lobe - high
angle into a QTH 125 Miles away. It would be very strong. Ask anyone who has
used one.

Subject: [CQ-Contest] QRP cheating
Felipe, With all due respect to your unique position I would think that many
would like to know what kind of antenna design devised by anyone, even Eric
NP3A "with a degree of antenna design" extant that could produce an equal
signal here at my QTH with the claimed 4.7 watts to NP4A's 1500 watts. This
would require an antenna capable of producing
25 db gain. Since my QTH is 125 miles SE of KP4 I would assume that this
supper antenna at KP4KE had an omni-directional pattern. If you know of such an
160 meter antenna design that is capable of producing
320 times the power, or 25 db gain, it would be worth millions in the
communications and broadcast industry. The claim that KP4KE's "double bazooka"
was capable of such performance when his 160 meter QRP "record"
was achieved defies all known existing laws of physics. As you stated "our
approach has to be scientific and fair for KP4KE" so why not explain to me what
antenna known anywhere in the world is capable of developing this kind of gain.
The picture KP4KE has published on QRZ.com shows only a modest installation
compared to that of Pedro, NP4A. At some point we can all benefit by knowing of
an antenna design capable of developing 25db omni- directional gain on 160
meters if such an antenna actually exists. You indeed have peaked my curiosity
on this subject.

It is not about changing the op, in this case Eric is an acomplished Rf
engineer and contester, with a degree of antenna design and lots of experience
in terrain modeling.
So the perspective of an operator with that profile could shed significant
light on the overal station performance, since certain QTH's have an advantage
over others as well as other antennas also bring that extra db, that can create
an overrall better performance of the station.
If we are going to stay true to our intention, our approach has to be
scientific and fair for KP4KE.. the information about his previous operations
is certainly valid and the committee Im sure is considering it and has
considered it, since I believe he has already been DQ for power claims. Im sure
there will be enought ways to compare during the contest.
How much these records make sense can easily be easily analized by looking at
other zone 7 and 8 QRP stations in the past, but I think thats another
discussion...
Lets wait if his commitment stands, he has failed his commitments before..

Felipe,
I don't know how just changing the operator will prove anything at all.
What I know to a moral certainty is the comparison on KP4TE alleged QRP signal
on ground wave and that of NP4A's full power signal from a great location with
a superb antenna system at the same time. This proved to me that KP4KE's claim
of running "4.7 watts to a double bazooka" when he established his published
record that his QRP" entry was totally bogus. The signal measurements made
here of the two stations in comparison do not lie.

To address Herb's comments:
We had an honest conversation with kp4ke regarding the questions around his qrp
and other operations.
HE has agreed to allow ERic Np3a to operate his station and to show the world
how his station performs in qrp, the official date set by him was on wpx cw
this year.
Certainly we are anxious as you to make sure that these were all valid entries,
let's wait for wpx and see.
