During this competition, the Changsha Blue Sky Rescue Team (BH7HA) participated, and I, as a station operator, achieved 184 QSOs, contacted 28 provincial administrative regions, and scored 6800 points. Thank you to all domestic and international stations that were able to communicate with BH7HA during the competition.
Equipment
This year, I used the 450D camera with a V750 antenna, along with foot-operated switches and a microphone, in addition to my existing headset. This setup freed up my hands and improved communication efficiency compared to using just a keyboard.
The antenna was mounted on the roof of the fifth floor, using a support pole approximately six meters long.
Results
This year, I completed 184 QSOs and earned 6800 points. I have achieved full communication with all radio stations in the domestic 0-9 area. Due to environmental factors, I was able to communicate with the northern part of Jilin Province this year. Communication with Qinghai, Tibet, Hainan (southern), Hong Kong, and Macau has not yet been established.
In foreign regions, Southeast Asia remains a hotbed of activity this year, although the number of incidents is relatively small, it still provides significant points.
A brief summary of events.
One week before the competition, I set up 750 antennas. The signals from my 15-meter station in Hebei Province and Hong Kong were both strong (59+) and stable, with clear audio.
On Saturday afternoon, I arrived at the competition venue after lunch. Immediately, I sat down in front of the radio to listen for the familiar BPM codes and standard signal broadcast from the timekeeping station. Once I heard them, I switched back to the 14 MHz frequency to begin the competition.
This year, as a member of BH7HA, I participated in the competition as part of team training activities. The BG7XP group leader from Changsha Wireless Radio Group provided technical guidance and logistical support to the team members.
Team members participate in call sign collection and training on using the competition software.
I had planned to stay up all night, but by around 12:30, I found that all the available stations were already connected. Since there weren't any new stations available, I decided to turn off my equipment and go to sleep.
The next day, I continued flying from 6 AM until around noon, and finally achieved my goal of matching last year's performance.
After lunch, we gave it our all until the very last second and successfully completed this competition.
Summary
In this competition, I further improved my ability to compete and decode weak signals, as well as practiced the application of letter recognition methods.
This year, the competition lasted for a relatively long period, but the scores were not significantly different from last year. Currently, the analysis suggests that this is due to weather and social factors. Last year's competition was cold, and participants were still wearing coats. In addition, there was no relaxation of restrictions. This year, the dust storms in northern China, combined with work-related reasons, may have resulted in fewer participants compared to last year.
Finally, I would like to thank all the domestic and foreign radio stations that were able to communicate with BH7HA during the competition.
If you need to exchange QSL cards, please use the card exchange center.
I wish everyone good results.
