Topband: How does KP4KE do it with 20 watts?

He claims he is using a "4 element vertical beam" to Europe. An 
optimized 4 EL array combined with proximity to saltwater might explain 
it, but that still seems like a big stretch. I remember sending an email 
to Ed @ D4B remarking on how loud he was here in W6 during one contest 
where he was active. He wrote back saying that his amplifier had died 
and that he was running low power during the entire contest. I couldn't 
believe it. Still going from 1500 Watts to 20 Watts is an 18.8dB 
deficit. That's a lot of dBs to overcome with antenna and QTH. 
Extraordinary claims demand extraordinary evidence. Seems like he should 
step up and provide a detailed description of his antenna system and 
QTH. Barring that, one is really left to wonder.

BTW, here is what K2KW was able to do with a single vertical on the 
beach with 5W during CQ WW CW 2003:

20W would be 6dB louder. Add gain from a 4 element array and good 
conditions then it might be possible to explain it given the great 
advantage of CW over SSB on topband. Of course K2KW made no secret of 
his antenna system and QTH. Same thing with D4B.
