As the 2025 Mulian Weir Field competition came to a close, various clubs and individuals were publishing their experiences and conclusions. While browsing articles from local clubs, I noticed that some of them included a mysterious number, as shown in the following example:
I'm not entirely clear on this numbering system. My initial guess was that clubs in Sichuan organized many radio stations to participate (as I saw several "BI8Ax" stations during the competition). They likely created a "amateur radio expedition fleet," assigning each station a QCxxx number. Out of curiosity, I consulted a WeChat group and received an explanation.
At this point, the questions were answered clearly. However, I also gained a deeper understanding of competition management through this experience: 1) clear material management, 2) standardized content formats, and 3) well-planned and managed participation.
These experiences are very valuable and worth learning from!
