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.
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
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.
