The following statistical data has been extracted from CQWW 2009 and CQWPX 2010 contests.

Number of logs received

The graph below shows total number of logs received in CQWW 2009 and CQWPX 2010 contests (CW and SSB). The Analyser downloaded and parsed all of the contest logs that were made public. Parsing and analysis is done automatically.

Number of logs received

QSOs in logs

Total number of unique QSOs found in submitted logs. Incorrect report, zones, modes, bands and so on are ignored. Invalid QSOs make up 2% to 5% of total numbers per contest. If a QSO is found in 2 logs it is counted only once (no double counting).

QSOs in logs

Total calls in logs

Total number of different calls found in logs. These figures include ALL calls logged by contest participants and are not representative of the real number of contesters. Most of these calls are incorrectly copied or “fake” QSOs. Further stats shed some light on how many operators really took part in CQWW and WPX.

Total calls in logs

“Real” calls

This graph shows numbers of calls that were found in at least 10 submitted logs. We can consider them “real” calls or “real” contesters. Others are either incorrectly received calls, “fake” calls or stations that are not serious enough about contesting. Only QSOs in correspondents’ logs are counted (own log QSOs are ignored). Basically, the following graph shows number of active contesters to date – whether they submitted their logs or not.

Real calls

Percentage of submitted logs

If we assume that 10 is a reasonable minimum number of QSOs made by “real contesters” (and I believe it is), the following graph shows the ratio of log submissions. I can only hope that the situation will improve with time.

QSO ranges, CQWW 2009 CW

These graphs show numbers of calls broken down by QSO ranges. HC8GR made over 8000 QSOs, LX7I, DR1A, CR3L made over 7000 QSOs, EE2W, LZ9W, DF0HQ, 6Y1V, EA8URL, UU7J made over 6000 QSOs and so on. As before only valid contacts are taken into account. Incorrect report, zones, modes, bands and so on are ignored.
