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
> year research project that examined two radio activities of
> world class cw entries in three classes (SOAB, SOAB/A and MS)
> of the 2006 CQWW contest. The project was possible because
> the CQWW Contest Committee decided to make logs from 2006
> onwards publicly available. An article, "Two Radio Events
> Signatures" has been prepared by Sylvan Katz, VE5ZX, and José
> Nunes, CT1BOH, after investigating the role that assistance
> from packet and a second operator has on the two radio
> signatures of the three classes.

> A two radio event (2RE) is a 'specific contiguous sequence of
> log entries', detectable by a log analyzer, that was likely
> 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
> minutes. These signatures may be useful to contest
> adjudicators to supplement UBN information in decision making
> activities.

> The article, accompanied by an Excel workbook with detailed
> calculations and charts, and zipped data files of the 2006
> CQWW cw logs and two intermediate data files (two radio event
> and Q rate profiles) is available at the Radio Sport Canada
