Trent, In all due respects such a high angle sky wave radiator would be
nearly useless in working DX station thousands of miles away. It amounts
to a cloud warmer A claim of the enhance signal by calling a dipole a
"double bazooka," assuming for a moment that 4.7 watts to this cloud
warmer was used as described, then how would it produce any radiation
angles low enough to even be heard 4000 miles away? I have a low dipole
here at 65 feet and I can assure you it is worthless in working any DX
compared to my 1/4 wave vertical. (A great RX antenna at SR periods at
times) I have run many comparison tests on RBN and SDR and know this
fact. during the Stew Perry contest I have struggled many times to get
serious and well known stations with great TX antennas, who really are
running QRP, in the log due to the increased point structure. It is
always a struggle to do so. Some of these ops admit calling for a hour
before getting a qrz partial from me and another 10 minutes or more to
get the call and exchange correctly.
I admire those stations who are truly QRP who work top band during
contests. I eschew heaping praise on those who claim to be QRP and are
clearly gaming the system.

A double bazooka at the distance you describe would have a massive lobe - high

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.
