CQWW Log Analysis – Two Radio Event Signatures

Posted on by

By: Sylvan Katz, VE5ZX and José Nunes, CT1BOH

“In the spring of 2007 José, CT1BOH, a world-class contester and a member of the CQWW contest committee, contacted Sylvan, VE5ZX, a contester and complex systems scientist. He had read an article Sylvan had written on amateur radio contesting. He wanted to know if Sylvan would be interested in working with him on a research problem.

José wanted to know if the CQWW cw logs could be used to find unique signatures for world class stations using two radios in the SOAB unassisted, SOAB assisted (SOAB A) and multi-operator one transmitter (MS) entry classes. Both SOAB classes and MS can use two radios. The single operator class can only have one signal on the air at a time (SO2R) while the MS stations can have two signals on the air, provided the second signal is used to work new multipliers. If unique signatures can be found then they might be useful for verifying the entry class of a log. This seemed like an exciting research project that would improve our understanding of radio sports and perhaps provide adjudicators with insights for techniques to aid decision making activities. So began an exchange of emails, telephone calls, spreadsheets, graphs and tables in search of two radio event signatures. The research reported in this article was completed in December of 2007.”

This is a very interesting article, which also shows why C4M was disqualified in CQ WW CW 2006.

Terrible propagation most of the weekend but I had a great time anyway
My SO2R skills are still improving and I pushed the second radio very hard this
time

Thanks to Peter, LA7SL we just managed to finish the 4-square for 40 in time
for the contest and it sure did help. It nearly equalled the 20 meter score!!!

Everything worked flawlessy except for some ghosts showing up in the shack the
last couple of hours. Maybe I should have slept more.........
