What are currently the (5 or 10) biggest amateur radio contests in terms of Worldwide participation (total number of stations or operators on the air during the contest)?

Are they the ones with "ARRL" or "CQ magazine" in the name or sponsorship? Or are there other organization generating contests with even greater participation?

  • $\begingroup$ Is their any form of data (published number of logs submitted or skimmer/reporter stats) independent of “who you ask”? $\endgroup$

  • $\begingroup$ There are some stats for the CQ WW contests: <cqww.com/stats.htm>, showing, for example, that last year's CQ WW SSB and CW contests had just below 8000 submitted logs each. $\endgroup$ Commented Oct 24, 2020 at 14:40

All major contests report detailed statistics for the benefit of contest participants, who want to know how they did in the contest. I compiled reported totals of logs submitted for several major contests. These numbers are not entirely consistent, because some contests include check logs and disqualified entries in the results, and some don't. The most recent numbers that I could find are reported, but these are not all in the same calendar year. I didn't report all contests, and it's quite possible that I missed contests that deserve to be on this list. (If so, let me know and I'll edit them in.) In some cases I had to add numbers to arrive at a total; I trust my addition, but I could have missed numbers that should have been included in the total. (Thanks to electronics-notes.com for giving me a list to start with.)

The list is sorted by logs submitted. I would think that the order of contests in the list would fluctuate quite a bit when comparing different years.

(In the table, "W/E" means "weekend".)

Yes, ARRL and CQ sponsored contests on HF are certainly among the "biggest" (I don't think any other contests draw larger participation than the CQ Worldwide DX and the CQ WPX contests). Other very popular worldwide ones include the Russian DX Contest, the Worked All Europe, the IARU HF Championship, or the All Asia contests.
