[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.
