[CQ-Contest] Corellating logs and spots

[Denis K7GK]

All this talk about packet cheating, public logs and christmas wishes made me wonder how hard would it be to write a small program that correlates (now public CQWW) logs and DX Cluster spots. Here is what I came up with in a few scarcely available hours.

http://home.comcast.net/~ac7lx/spotStats.zip

The archive contains a command line executable (no fancy UI = time savings), readme.txt file with some help, sample cabrillo log and a capture of cluster spots found on JG1VGX's web site for CQWW CW 2006. Rin's site (http://www.jg1vgx.net/en/) also has the cluster spots for CQWW SSB for the same year.

The program calculates the numbers and percentages of frequency jumps found in the log where QSOs are made a short time (5/10/20 min) after the same call appeared on the DX Cluster. To get an idea whether someone might have used a cluster I compare an output produced with two control logs - a known non-assisted entry, a known assisted entry and with the log in question, all from the same geographic area. The output is very much open to interpretation and in my experience does not provide hard evidence of cheating. But sometimes I find the information produced in this way quite interesting.
