Excellent analysis, Tonno !
Questions for the rest of you:
- Does anyone believe that RD3A was not cheating ? If so, please explain your
- Does anyone still believe that packet cheaters cannot be caught ?
It is most disappointing that this kind of analysis is not being applied to all
SOAB-claimed logs by the contest adjudicators. In the 2006 CQWW CW results, I
know of one case where a high-scoring (top-20) USA competitor said he was
SOAB-Assisted in his 3830 writeup, but (accidentally) submitted his log as
SOAB-Unassisted. Surely this kind of analysis, done by the log-checkers, would
have detected and questioned his error.

time urge hime and the others to bring evidence to light and put more peer
pressure on the cheaters until CQ Committee will take appropriate action.
Trying to lead the way here is my letter about RD3A analysis to another
relfector a month ago (this is ES5TV, 73):
