After arriving at the "base", Duan Fei and the others once again conducted a test of the antenna feeder system, radio station, computer and other equipment. Since they were participating in a multi-crew competition, there were two radio stations in total, one of which served as the main call station and the other as a coefficient station.

According to the rules of the competition, at the same time, a maximum of two different bands are allowed to have a transmitted signal. Both stations can be connected to any station. However, a radio station can only be connected once on a band, no matter which radio station you use.

In fact, these debuggings have been prepared for a long time, and for the sake of insurance, Duan Fei and the others still re-checked the communication between the calling station and the coefficient station, as well as the specific situation of the software interface, in case there is a problem at that time, so as to waste time to temporarily debug.

Due to the long time of the competition, they specified a more detailed check-in schedule, in addition to Duan Fei, Xu Wenle, Wu Bai and Yi Pengfei The four main forces, as well as several well-known hams in Beijing City, also joined their team, and it is expected that the number of participants by then can reach a total of eight to nine people. These people are the backbone members of the Beijing City Radio Amateur Club.

In addition to the main check-in staff, there are several female students who serve as logistics, among which Xu Wenjing also volunteered to join them. Of course, it's more just a name, and most of the time she will follow Zhong Yun to introduce her to the whole process.

All in all, it was a very large team, and in order to accommodate so many people, their original engineering hut had been expanded to triple its original size. Fortunately, this is an engineering house, and if you want to expand, you only need to remove one of the walls and add a steel structure wall, which is very convenient.

Compared with the huge momentum of the capital, Lin Hong, who is in the countryside of Tanglin City, is a little too deserted here.

In order to be able to meet this competition in the best mental state, Lin Hong did not continue to do something at night as before, but deliberately lay in bed to rest for a few hours.

He had now mastered some of the tricks, and although he still couldn't sleep, he could lie down or sit quietly and close his eyes and recuperate, emptying his mind of all the thoughts in his mind, and letting his mind fall into a state of emptiness, which seemed to work well, for his frequent dizziness seemed to have lessened a lot.

At 6:00 Beijing time, Lin Hong opened his eyes on time, got up and washed, and began to go home to make breakfast.

This time, he made a bit of a large portion, and in addition to his own and his father's portions, he also prepared the portion he ate at noon.

Now that the temperature has turned cooler, leave it for half a day, and the food will not spoil.

What he made today was not porridge or anything like that, but steamed rice. In the south, it is also common to eat rice, and it tastes very good when you scramble two eggs and get some appetizers such as moldy tofu and pickled vegetables.

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

For his son, Lin Changming has completely let go of his son since the incident of "taking the blame" a few years ago. As Xu Lao said, his son is extraordinary, more mature than his peers, and being too restrained may have an adverse impact on him.

Lin Hong looked at the time, it was already 7:42, and there were only 20 minutes left before the start of the game. So I walked quickly towards the scrap yard with my lunch box.

By the time he arrived, it was 7:55.

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

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

Since it is a CW (equal amplitude telegraph) mode of competition, all communication methods are connected using Morse code signals, so what everyone hears in the headphones is a "tick" long and short sound.

Lin Hong first adjusted the frequency band to 20 meters.

"Da Di Di... Da Di Di... Da Da Di Di ......"

As he rhythmically pressed the electric key with his right hand, a wireless signal with the content of "bd7xzz_contest" started from the electric key, passed through the radio station at the speed of light, and passed through the ten-meter antenna, announcing to the world that he Lin Hong had officially started the competition!

At this moment, there are a lot of signals on the 20-meter band, forming a signal peak, but it may be due to the daytime, the background noise has gradually become louder, Lin Hong just tried to directly not apply the "adaptive signal filter" he made, and found that the model is only "36", although it can barely be received, but the efficiency is much lower.

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

Lin Hong soon established the first QSO (direct communication) communication with a ham in Hangzhou, and the other party was also a contestant, so after exchanging signal reports with each other, the two ended the communication by saying "73" to each other.

It's as simple as that, the two sides didn't spend extra time talking about anything else, just confirmed each other's communication, and then went to find the next target again, without any dragging.

The numeric code "73" is a slang term in the world of ham that indicates a friendly greeting at the end. In fact, at the beginning, "73" was specially used for blessings between couples, representing "my_love_to_you", and later the meaning gradually blurred, gradually changing from a lover's blessing to a general signal code for the friendship between hams.

In radio communication, a variety of signal shorthand codes are very common, which can greatly improve the efficiency of communication between each other.

Five minutes later, Lin Hong had successfully established 25 valid QSO connections with other hams, all but one of which was from "foreign" Hong Kong, and the others were hams from different parts of China. (Note: The state here does not refer to the state in the political sense.) ）

According to the regulations, there are a total of 10 0-9 zones in the sub-divisions of amateur radio stations in our country. For example, Beijing belongs to Zone 1, while Xinjiang and Tibet belong to Zone 0.

While communicating, Lin Hong used a pen to fill in the ham call sign, time, band, and frequency point that he had communicated with him on the special form for the game that had been prepared for the competition...... And so on.

This information must be mailed to the CQ magazine after the competition, so Lin Hong remembered it very carefully, and it was all written in English, and it was a standard printed type.
