In the era of pure radio, the predecessors of the amateur radio industry had few auxiliary tools, and the personal computer was actually something more rare and mysterious than the radio itself, so the information such as the radio diary was recorded in the notebook one by one, and they sent back QSL cards to each other, and manually counted the data of the communication with the pen, which was very complicated, but they enjoyed it, because this was one of their pleasures.

With the advent of personal microcomputers on the stage of history and the rapid development of the rapid trend, the PC has gradually entered the field of vision of hams. Ham itself is a group of highly intelligent people who are willing to accept new things and challenges, and when they discover that the PC has even more fun than radio, and more puzzles are waiting for them to explore and discover, many ham have turned to the world of computers. They discover that the world is a whole new continent that is much more expansive and unearthed, more mysterious and freer than the world of radio.

Of course, the vast majority of hams do not completely abandon their identity as hams, but are often active in these two somewhat related but very different worlds.

Over time, Ham began to think about how to put computers to work for his radio career.

One of the powerful functions of the personal computer is statistics and calculations, and when the radio is communicating, the workload of counting the communication data is extremely large, which usually takes a lot of time for the hams, and sometimes it may have to be restarted because of a small statistical error.

As a result, a variety of software specially designed to assist hams in amateur wireless communication gradually appeared, and due to the natural convenience of long-distance communication of hams, everyone spread these software in their own circles, shared the experience of using the software, and constantly gave feedback to the software authors on the use of the software, improvement suggestions and various bugs (defects).

Some authors have come to the fore with software that is not only powerful, dedicated to ham, but also, and most importantly, free. Everyone is more than happy to share their work with their friends, so that they can enjoy the convenience they have brought to them.

In the Handbook of Amateur Radio Amateur Guidelines recognized by the amateur radio community, there is this guideline:

"Fraternity - Sent slowly and patiently upon request, guided and discussed in a beginner-friendly manner, with kind help, cooperation and consideration for the benefit of others."

Clearly, these software authors are quietly following these traditions handed down by their predecessors, without which the world of amateur radio might have been in chaos and disorder, rather than as it is now full of joy and warmth.

The world of amateur radio is a world full of warmth, although the radio waves are formless and colorless, and the night sky is cold and silent, but the radio waves are warm, carrying everyone's blessings and greetings, crossing the mountains, crossing the sea, and connecting people of different nationalities and countries closely. Although everyone may not understand the language and everyone is completely unfamiliar before, as long as you report your call sign, whether you are a master or a rookie, you will be warmly welcomed and guided.

The software that Duan Fei got was one of the more popular radio diary software, logger32, the author of this software is Bobfurzer, call sign K4CY.

The interface of the software is all in English, Duan Fei's English level is obviously good, and he is also very familiar with this software, and it is easy to operate. Xu Wenjing, on the other hand, has not yet reached his level, and coupled with his unfamiliarity with the software, it is a little difficult to just watch from the sidelines.

However, she also saw that logger32 is very powerful, greatly simplifying the process of logging and statistics, as long as the key parameters are entered, it can be automatically calculated and counted, and, through some special interfaces, this software can also be directly connected to the relevant interface of the radio station for data detection and monitoring.

On the right side of the app, there is even a window that displays a map of the world, on which she can show the actual location of the stations that appear during the connection, as well as the trajectory and coverage of amateur satellites in the sky.

This feature is especially useful for amateur radio enthusiasts, as it shows the world as you see it centered on your location, and the distance on the map is proportional to the actual distance.

The operator can easily determine the direction of the communication station through the parameters displayed above, so as to adjust the pointing and frequency of the antenna, and can also intuitively reflect the communication path and distance.

"Brother Fei, it seems that you are really well prepared." Xu Wenjing said sincerely.

"Of course." His brother Xu Wenle walked over with a power amplifier at this time, "We have all decided, if we haven't been able to win the Asian championship of multi-person single crew, we will cancel our license from now on and never play radio again!" ”

Xu Wenjing couldn't help but stick out her little tongue when she heard this, but she knew how much his brother's gang loved radio, how could she say that she would put it down when she played it from childhood to adulthood? It can be seen how persistent they are about the result of the game this time.

"Brother Fei, I want to write a newsletter and submit it to the newspaper, do you think it's appropriate?" Xu Wenjing took out her camera, took a picture of the radio station and asked.

"Absolutely." Duan Fei said with a smile, "But you still don't want to write about the antenna outside, it won't affect ......."

Duan Fei didn't go on. These antennas were originally erected according to military standards, and if this was also reported, it would have a very bad effect.

"Hmmm! I get it. Xu Wenjing has been exposed to these things since she was a child, so she naturally knows what to do.

So, Xu Wenjing wrote a newsletter on the matter, and finally voted for the Central People's Radio in the name of their school news agency. Perhaps because of the nature of the radio station, they were very interested in the matter, and they quickly broadcast this article in the news of the day, with the title "Amateur Radio International Competition is Coming, Beijing Ham Gathers Together to Actively Prepare for the Competition". Not only that, Zhong Yun, an intern reporter at the radio station, contacted Xu Wenjing on the same day and said that he would follow up and report on the matter.

"The cqww_dx competition is a grand event in the amateur radio world organized by CQ Radio Magazine in the United States, and every year on the last weekend of November, that is, two days later, UTC, there will be a competition in CW mode, that is, in the equal amplitude telegraph communication mode, and ham people all over the world are actively preparing for it during this time...... In our capital, there is also such a group of hams actively preparing for this competition, and they ......"

The clear and beautiful voice of the announcer of the Central People's Radio came from the radio, and Lin Hong, who was busy on the workbench, glanced back at the radio station at this time and muttered: "There are quite a few people in China participating in this competition." ”
