Rewind the clock to half an hour ago.

"It's coming, it's coming!" Xu Wenle shouted loudly, "The pile-up of Europe is coming!" ”

Wu Bai smiled: "Hehe, it's just in time, it's best to block all of Little Japan!" ”

"Everyone's cheering up, it's time for us." Duan Fei also cheered everyone up, "Whether you can win the championship in this competition depends on the next period of time." ”

In their plan, the pile-up signal blowout of Radio Europe is a very important part. The reason for the construction of such a powerful antenna is to be able to break through the natural blockade formed by European signals.

Most of the basic scores, as long as there are no accidents, everyone can get in the bag, even if the basic score is a few hundred points or thousands of points, the impact on the final score will not be great.

The key is the coefficient score.

There are only so many total points for coefficient points, and whoever gets more points has a greater advantage.

In the past, due to the impact of the peak of the pile-up signal in Europe, it was difficult for ham in Asia to connect with the vast regions and countries in Africa. The final gap is also reflected here.

In order to successfully obtain the coefficient score of African countries during this period, in addition to excellent communication skills, it is necessary to have radio equipment with quite good performance.

Improving the performance of radio equipment can generally be done in two ways.

On the one hand, it is to improve the ability of the station to filter background noise, so that it can effectively separate the valid signal from many invalid signals. On the other hand, it can increase the receiving and transmitting power of the antenna, and correspondingly improve the transmission and reception efficiency of the antenna.

For the former, Duan Fei once consulted experts and professors in the field of radio, except for some high-end military equipment, most of the current radio equipment in the performance of background noise filtering is similar, there is no particularly obvious change. And even if there is such technology, it is highly classified information by the military and will not be easily disclosed.

So Duan Fei and the others hit the idea on the antenna. Since the antenna power is too short, then lengthen it and add it to 160 meters, which is always okay, right? If you can't erect it yourself, then borrow the east wind, where to borrow it? Naturally, the troops. Duan Fei's small circle can only be mobilized in the army, after all, the relationship between their parents is here.

So they spent a lot of effort and begged a lot of people, and only then did they take advantage of the opportunity of upgrading a certain electronic countermeasures battalion to successfully borrow the current shareholder wind.

Now it seems that their efforts are not in vain, the 160-meter ultra-long antenna is cool to use, the signal strength is leveraged, except for a few cases where the other party's own transmission power is not forced, the signals they receive are basically all "599".

However, these ordinary conditions in the early stage are a bit of a "hero useless" feeling for their ultra-long antenna, after all, other hams can achieve the same effect with a ten-meter-long long antenna or a more powerful Yagi antenna.

It is only at this moment that the 160-meter ultra-long antenna really begins to exert its power.

At this moment, Duan Fei and his parents went into battle, began to adjust the frequency, and began to search for the radio station in the direction of Africa.

Soon, he had a successful relationship with a ham in South Africa.

He skillfully and rhythmically pressed the electric key to send his call sign to the other party, and after the two sides exchanged signal reports, Duan Fei did not immediately disconnect as before, but asked one more question:

"Before that, did you have contact with Asian ham?"

Although he felt that his question was a bit excessive, he could not rule out that there were probably "super hams" like them among Japanese hams, so he couldn't help but ask.

However, he was very shocked by the other party's answer, and the other party had already contacted another ham in China ten minutes ago. And, from the description of the South African ham, it seems that the ham is highly respected.

Due to the time constraints, South African ham just said a few words, and immediately said "73" to end the communication.

"There's even a Chinese ham that has been connected?" After everyone heard the news, they were first stunned, and then they thought that the other party was very likely to hit the big luck, and just let him establish a communication from the gap in the shielding net.

Duan Fei continued to search for the prefix of rare countries in Africa, and soon he successfully established contacts with Egypt and Nigerian ham. This time, he still asked the same question before ending the connection.

However, to everyone's shock, they got the same answer.

"Who else is so bullish in China?" Xu Wenle asked the same question in everyone's mind.

If there is only one time like this, then it can be considered that the other party has taken shit luck and is accidental, but it is inevitable that such situations will happen one after another.

Judging from the news they just got, it was obvious that the other party was ahead of them, and the few hams they had connected to had been taken by the other party before, which had to shock them. You know, their combination at the moment can be said to be the most luxurious lineup in China. They have this self-confidence.

Who is the other party?

"Brother Fei, the next time you communicate with other hams, ask the other party's call sign by the way. Such a powerful master can't be an unknown person, and it is likely that we still know each other. Wu Bai suggested on the side.

Xu Wenle also agreed: "Yes, we basically know that the better ham is played in China. ”

The circle of amateur radio says that it is not small, but it is not big. Everyone is calling in the air every day, so they can naturally get familiar with it quickly, and as long as there is a call sign, they can basically know who the other party is.

Duan Fei continued to communicate, and this time he connected to a Moroccan ham. Not surprisingly, they once again fell behind the man. Duan Fei hurried up and immediately asked about the other party's call sign, and the Moroccan side sent the call sign very happily.

Duan Fei brushed the pen on the paper one by one.

“b… d… 7… x… z… z”

"bd7xzz, level 2 license?" When Duan Fei saw this call sign, his brows couldn't help frowning. He was rather unfamiliar with the call sign and had no effect at all. However, this is a bit unreasonable, there are few people who hold a second-level license in China, when did such a bull come out?

"Which of you has communicated with this call sign?" Duan Fei pressed the paper directly on the wall and asked everyone.

Xu Wenle, Wu Bai and Yi Pengfei shook their heads one after another, and the members of the Radio Club were also at a loss, none of them had communicated with this person.

"It's impossible, this is obviously China's call sign, and it's a second-level certificate, and we haven't even communicated with each other?" Duan Fei was surprised.

After asking a few questions, he took off the piece of paper and put it in the drawer, deciding to wait until the game was over and then go to the Radio Association to check it.

Immediately afterwards, Xu Wenjing, Zhong Yun and several other girls walked in from outside with plastic bags in their hands.

"After eating, everyone is hungry." Xu Wenjing said loudly, "Fight again after eating." ”

It was so remote that it took them more than two hours to get them back from a nearby town.
