Chapter 50 BD7XZZ Competition!

After arriving at the "base", Duan Fei and others once again tested the antenna feed system, radio station, computer and other equipment. Because they are participating in the multiplayer dual-unit competition, there are two radio stations in total, one of which is the calling station and the other is the coefficient station.

According to the rules of the game, signals can be transmitted at up to two different bands at the same time. Both radio stations can be connected to any radio station. But a radio station can only be connected once in one band, no matter which radio station you use.

In fact, these debuggings have been prepared for a long time. To be on the safe, Duan Fei also re-tested the connection between the caller and the coefficient platform, as well as the specific situation of the software interface, in case there is a problem at that time, thus wasting time on temporary debugging.

Due to the long time of the competition, they designated a more detailed check-in schedule. In addition to the four main players, Duan Fei, Xu Wenle, Wu Bai and Yi Pengfei, several well-known hams in Beijing have also joined their team. It is expected that the total number of participants can reach eight to nine at that time. These people are all key members of the Beijing Amateur Radio Enthusiasts Club.

In addition to the main check-in personnel, there are also several girls in charge of logistics, among which Xu Wenjing also volunteered to join. Of course, it's just a name. Most of the time, she will follow Zhong Yun to introduce her the whole competition process.

In a word, this is a very large team. In order to install so many people, their original engineering hut has been expanded, which is three times the original area. Fortunately, this is an engineering house. If you want to expand it, you just need to tear down one of the walls and then add a steel wall, which is very convenient.

Compared with the great momentum of Beijing, Lin Hong, who is in the countryside of Dongling City, is a little too deserted.

In order to welcome the competition with the best mental state, Lin Hong did not continue to do something at night as before, but deliberately lay ** for a few hours.

He has gradually mastered some skills. Although he still can't sleep, he can lie quietly or sit and close his eyes to refresh himself, empty all the thoughts in his mind, and let his mind fall into an empty state. This kind of rest seems to be good, because he often feels dizzy. It has been reduced a lot.

At 6:00 Beijing time, Lin Hong opened his eyes on time. After getting up and washing up, he began to go home to make breakfast.

This time, he made a little large portion. In addition to the portion of himself and his father, he also prepared the portion he had for lunch.

Now the temperature has turned cold. If you leave half a day, the food will not go bad.

What he made today is not porridge or something, but steamed rice. In the south, it is also common to eat rice. Stir-fry two eggs and make some moldy tofu, pickles and so on. It tastes very good.

When the meal was ready, his father, Lin Changming, also got up. He hurriedly had breakfast and said a few words, and then rushed to the car and wood factory. Recently, the factory has received another batch of orders to be completed before the delivery deadline, and now the manpower is a little insufficient, so he, the factory director, can only do more part-time technicians.

For his son, Lin Changming has completely let go since the incident of "begging for guilt" a few years ago. As Mr. Xu said, his son is extraordinary, more mature than his peers, too bound, and may also have a negative impact on him.

Lin Hong looked at the time. It's 7:42 now, and there are less than 20 minutes left before the start of the game. So he quickly walked to the waste collection station with the lunch box.

It was already 7:55 when he arrived.

Lin Hong also took time to go to the toilet, and then poured himself a cup of tea.

At 7:58, Lin Hong finally turned on the radio slowly, put on the headphones, and began to adjust the frequency to the North American competition frequency point in the 20-meter band. He was very punctual and clearly heard the opening signal from there.

Because it is a CW (equivalent telegram) mode competition, all connection methods use the Moss code signal for connection, so what everyone hears in the headphones is a "tick" long and short sound.

Lin Hong first adjusted the frequency band to 20 meters.

"Dad drip...dap drip...dap drip..."

As he pressed the electric key rhythmically with his right-hand electric key, a wireless signal of "BD7XZZ_CONTEST" began with the electric key, passed through the radio at the speed of light, and announced to the world through the ten-meter antenna that he had officially begun to participate in the competition!

At this moment, there are many signals in the 20-meter band, forming a signal peak, but perhaps due to the daytime, the background noise has gradually become louder. At the beginning, Lin Hong began to try to receive messages directly without applying the "adaptive signal filter" he made, but found that the model was only "36", Although it is barely possible to receive letters, the efficiency is much lower.

Therefore, he had to connect his "signal filter", and a very clear ticking sound immediately came from the headphones.

Lin Hong soon established the first QSO (direct connection) connection with a ham in Hangzhou after the competition. The other party was also a contestant, so after the two exchanged signal reports with each other, they said "73" to end the connection.

It's so simple. The two sides didn't spend extra time talking about other content at all. After confirming the connection with each other, they went to find the next goal again without any procrastination.

The number code "73" is a slang word in the world of ham, indicating a friendly greeting at the end. In fact, at the beginning, "73" was specially used for blessings between couples, representing "My_love_to_you". Later, the meaning gradually blurred, and gradually changed from a lover's blessing to a general signal code of friendship between hams.

In radio communication, a variety of signal shortcodes are very common, which can greatly improve the efficiency of communication between them.

Five minutes later, Lin Hong has successfully established 25 effective QSO links with other hams. Except for one from "foreign" Hong Kong, the others are hams from different divisions in China. ( Note: The country mentioned here does not refer to the country in the political sense.)

According to the regulations, there are a total of ten 0-9 zones for amateur radio stations in China. For example, Beijing belongs to District 1, while Xinjiang and Tibet belong to District 0.

While connecting, Lin Hong used a pen to fill in the ham call sign, time, band, frequency point... and other details on the prepared special form for the game.

This information must be mailed to the American CQ magazine after the competition, so Lin Hong remembers it carefully, and it is all written in English, and it is a standard print.
