  Time went back half an hour ago.

  "Here it comes! Here it comes!" Xu Wenle shouted loudly, "The European pile-up is coming!"

  "Wo Bai laughed and said: 'Hehe, just in time, it's best to shield all the little Japanese departments!'"

  "Everyone cheer up, our time has come." Duan Fei also encouraged everyone, "Whether this competition can win the championship or not depends on the next period of time."

  In their plan, the pile-up signal of European radio is a very important part. The reason for building such a strong antenna is to break through the natural blockade line formed by European signals.

  Most of the basic points, as long as there are no accidents, everyone can put them in their pockets. Even if the basic points differ by a few hundred or thousands, they will not have a great impact on the final score.

  The key lies in the division of coefficients.

  The total score of the coefficient division is limited, whoever gets more points has a greater advantage.

  In the past, due to the peak period of European pile-up signals, it was difficult for ham radio in Asia to contact the vast areas and countries in Africa. The final gap is also reflected here.

  To successfully obtain coefficients from African countries during this period, in addition to requiring high communication skills, they must also have wireless telegraphy equipment with quite good performance.

  Improving the performance of wireless equipment can generally be achieved from two aspects.

  On the one hand, it can improve the radio's ability to filter out background noise and effectively separate effective signals from numerous ineffective signals. On the other hand, it can increase the antenna's receiving and transmitting power while also improving the antenna's transmission efficiency.

  As for the former, Duan Fei had consulted experts in the field of wireless electronics before. Except for some high-end military equipment, most current wireless electronic devices have similar performance in terms of background noise filtering, with no significant changes. Moreover, even if such technology exists, it belongs to highly classified military information and will not be easily made public.

  So Duan Fei and his team set their sights on the antenna. Since a too-short antenna wouldn't work, they decided to lengthen it to 160 meters - that should do the trick, right? If they couldn't set it up themselves, then they'd borrow from others - specifically, the troops. After all, Duan Fei and his small circle of friends only had connections within the military, since their parents' relationships were all in this area.

  They spent a lot of effort and asked many people, and only managed to borrow the current shareholder wind by taking advantage of an upgrade opportunity at a certain electronic counter-camp.

  It seems that their efforts were not in vain, the 160-meter ultra-long antenna is great to use, with a strong signal strength, except for a few cases where the other party's transmission power was insufficient, the signals they received were basically all "599".

  However, for this ultra-long antenna, the ordinary conditions in the early stage have a bit of a "hero has no use for his skills" feeling, after all, other hams can achieve the same effect with a 10-meter long wire antenna or a slightly stronger Yagi antenna.

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

  At this moment, Duan Fei and his father are on duty, adjusting the frequency and searching for radio stations in the direction of Africa.

  He soon established communication with a ham in South Africa.

  He skillfully and rhythmically pressed the telegraph key, sending his call sign to the other party. After exchanging signal reports with each other, Duan Fei did not immediately disconnect like before, but instead asked another question:

  "Have you ever been in contact with ham radio operators in Asia before?"

  Although he thought the question was a bit unnecessary, he couldn't rule out that there might be "super ham" like them in Japanese ham either, so he still couldn't help but ask.

  However, the other party's response shocked him, as it turned out that they had contacted another ham from China just over ten minutes ago. Moreover, from the South African ham's description, he seemed to hold that ham in extremely high esteem.

  Due to time constraints, the South African ham just said a couple of sentences before immediately saying "73" and ending the communication.

  "Could it be that there is actually another Chinese ham radio contact?" Everyone who heard the news was first stunned, and then thought that the other party might have been very lucky, and happened to establish contact through a gap in the firewall.

  Duan Fei continued to search for the rare countries of Africa, and soon he successfully established contact with Egypt and Nigeria again. This time, he still asked the same question before ending the communication.

  However, what shocked everyone was that the answer they got was also the same.

  "Who else in the country is so awesome?" Xu Wenle asked out of everyone's consistent doubts.

  If it only happened once, then one could think that the other party was just lucky, but when such situations occur one after another, it's a necessity.

  Judging from the news just received, it is clear that the other side has taken the lead. The several hams they connected to were actually all seized by the other side before, which shocked them. It's worth noting that this combination at this moment can be said to be the most luxurious lineup in the country. They have this confidence.

  Who is he after all?

  "Fei Ge, next time you're in contact with other ham radio operators, ask them for their call sign. A master like this can't be a nobody, it's possible we know him." Wu Bai suggested from the side.

  Xu Wenle also chimed in: "Right, domestically-made ham is pretty good, we basically all know that."

  The circle of amateur radio is not small, but it's not big either. Everyone calls each other in the air every day, so they can get familiar with each other quickly, as long as there is a call sign, you basically know who the other person is.

  Duan Fei continued to contact, this time he contacted a Moroccan ham. Without exception, they fell behind that person again. Duan Fei seized the opportunity and immediately asked for the other party's call sign, and Morocco quickly sent over the call sign.

  Duan Fei swiftly wrote down one after another on the paper with his brush.

  “b…d…7…x…z…z”

  "BD7XZZ, a second-class license?" Duan Fei's eyebrows furrowed as he saw this call sign. He was quite unfamiliar with this call sign and had no impression of it at all. But this was simply unreasonable - people who held a second-class license domestically were extremely rare, when did such an expert appear?

  "Who among you has been in contact with this call sign?" Duan Fei posted the paper directly on the wall and asked everyone.

  Xu Wenle, Wu Bai and Yi Pengfei all shook their heads, the members of the Wireless Club also looked confused, none of them had ever contacted this person.

  "Impossible! This is clearly a Chinese call sign and it's a secondary certificate, how could we have not communicated with each other?" Duan Fei was greatly surprised.

  He asked two questions and then tore off the paper and put it in the drawer. He decided to check with the Wireless Association after the game was over.

  Immediately afterwards, Xu Wenjing and Zhong Yun, along with several other girls, walked in from outside, each carrying a plastic bag.

  "After eating, everyone must be starving!" Xu Wenjing said loudly, "Let's eat and then fight again."

  It's really too remote here, they spent more than two hours buying these things back from the nearby town.
