[CQ-Contest] CQWW CW Two Radio Event Signatures

[Randy Thompson]

Congratulations to CT1BOH and VE5ZX on their scientific application of a
technique for log analysis.  Even if you only read the charts, it is clear
that SOAB, Assisted, and Multi-single operations have different signatures
that are amazingly similar around the world.  Once this is accepted, it
becomes possible to test logs against this technique and evaluate whether
they need additional checking.

Thanks also to CQ for making all of the contest logs available.  That was a
brave decision and one that has been all positive.

I definitely recommend taking a few moments and reading the article.

Randy, K5ZD

> Radio Sport Canada is proud to present the findings of a one

> produced by the use of a second radio or an operator and a 
> second radio. Information gathered from 2006 CQWW contest 
> logs for world class high power cw stations were used to 
> produce 2RE signatures. A 2RE signature describes the 
> probability of a 2RE occurring at various run rates. The 
> profiles of these signatures are uniquely distinguished in 
> various entrant classificatoins by the likelihood of 2REs 
> occurring at high QSO rates. The more assistance a station 
> receives the more likely it will log 2REs during high Q rate
