Chapter 52 Add some ingredients to them

At 7:30 a.m., Dongling Radio Monitoring Station.

Xiao Zhang, who had just been assigned from school, came to work early as he did a few weeks ago. He opened the security door of the monitoring room with the key, and then turned on the monitoring equipment with excitement. Today, it was not his turn to be on duty, but Lao Du, the master in charge of taking him. However, because he was very interested in these equipment and enjoyed the process very much, he wanted to do something for his master to thank him for his careful teaching these days, so he took over Master Du on duty on Saturday morning.

This is the case for young people, especially the students who have just graduated from school and have been assigned to a new unit. They are full of energy and can't wait to work 24 hours a day.

Xiao Zhang finished eating the deep-fried dough sticks and soy milk in his hand a few times, and then began to work.

He felt that he liked this job very much. He monitored the radio status of the whole Dongling City every day, giving him a feeling that he had everything in his hands. Moreover, sometimes, when abnormal situations are found, they can also monitor the specified signal, which is like eavesdropping on other people's secret conversations, which is extremely exciting and fresh.

As taught by his master, he turned on several monitoring devices and listened slowly in the order of wavelength from short to long.

In fact, their work is very leisurely. There are only a few places in Dongling City that send radio signals to the outside world every time, and he is a little familiar with it. For example, the stationmaster of the radio monitoring station has a radio station at home, which is played by the stationmaster's son. There are also several members of the amateur radio club in the city. Oh, by the way, there is another awesome man, specially explained by the master, located in Xinfu Town, Dongling City. Master said that no matter what the other party is doing, don't worry about it or listen to it, otherwise you may get into big trouble.

It may be early. At this moment, there are few signals, but intermittent signals are detected in the direction of the stationmaster's home. Listening to the content, it seems to be a CW signal. As for the specific content, Xiao Zhang is a little blind. Before work, he had never learned the Morse code. Although he had heard of it when he was studying before, he had never really memorized and used it.

His top priority every day is to learn Morse code. According to the master, if the staff of the monitoring station don't understand this, how to monitor it?

"Huh?"

Xiao Zhang, who was listening responsibly, suddenly found that the signal in the frequency band began to increase for a while. He looked at the wall clock, and the pointer was exactly eight o'clock at this moment.

This seemed to be a mysterious command. Xiao Zhang found that the frequency band suddenly became extremely lively. It took less than a minute from extreme silence to extreme hustle and bustle. Everyone seemed to be better and better, sending signals from eight o'clock.

"What's going on?" Xiao Zhang quickly picked up the headphones of other radio stations and listened to them, and found that it was the same in other bands. He panicked. He had never encountered such a situation, and his master had never told him.

"Is there any conspiracy in this?"

An idea suddenly flashed into Xiao Zhang's mind. Since he became a staff member of the monitoring station, he has been looking forward to the day when he can find a signal of an enemy and then bring the other party to justice.

Thinking of this, his heart pounded involuntarily. He no longer hesitated. He took off the headphones and immediately ran to the monitoring room. He wanted to go to the stationmaster's office and report this important situation to him!

But he just didn't run far, but he met his master Lao Du halfway.

Although his apprentice Xiao Zhang said that he would help him on duty today, Lao Du, who was rigorous, still came over. After all, Xiao Zhang was not very reliable. Lao Du let him stay alone and was a little relieved.

Lao Du saw Xiao Zhang running over with a panicked face, stopped him directly and asked, "Xiao Zhang, what's wrong with you?"

"Master, are you here? That's great!" Xiao Zhang's face showed surprise. He said hurriedly, "I found something abnormal and wanted to report to the stationmaster!"

Lao Du looked at him doubtfully: "Unusual situation?"

"Yes, when I was just monitoring... Hey, Master, come and listen to it yourself. I can't say it." After Xiao Zhang finished speaking, he turned back and ran to the monitoring room.

"Xiao Zhang, it's still a little rough." Lao Du shook his head leisurely and followed him step by step.

"Master, hurry up." Xiao Zhang said anxiously when he saw this.

"Old man, my legs and feet are a little uncomfortable."

Lao Du gave him a cold humor, and then slowly sat down on the chair, picked up one of the headphones and listened.

Xiao Zhang looked around for a long time and didn't see any clear meaning from the master's face.

"Master, what's going on? Isn't this signal abnormal? Is there any conspiracy (Mao)? Xiao Zhang's hometown is a coastal city in the south. He had a little accent to say no to talk. In this emergency, he said the conspiracy as **.

"**Fass!" Lao Du laughed and scolded and continued, "These are those stinky kids participating in the amateur radio competition!" I've been asking you to memorize Morse for a long time. Why don't you ignore my words?

"I have it on my back!" Xiao Zhang smiled embarrassfully. He knew that he had made a mistake again, and he was secretly glad that the master came in time, otherwise he would have made him cry if he poked the matter to the stationmaster.

"Master, what's going on with the game you just mentioned?"

"Today is the last weekend of November, and there is a major event..." Lao Du briefly told Xiao Zhang about the CQWW_DX competition. "These things are basically necessary to know. I'll give you the basic internal information later. I'll read it carefully so that I won't make such low-level mistakes in the future."

"Thank you, Master! You are so kind to me that I don't even know how to thank you!"

"Stinky boy, just don't make trouble for me." Lao Du shook his head with a smile. Although the child was a little rash, his mouth was quite sweet and he could be a man. Lao Du was also willing to give him more advice.

"Master, I still have a question." Xiao Zhang hesitated for a moment. Seeing that his master was in a good mood, he finally summoned up the courage to say, "What if someone takes this opportunity to fish in troubled waters and send illegal signals to the outside world? In this way, can't we monitor it?"

"You, why don't you give up?" Lao Du didn't know whether to laugh or cry. "In theory, it is possible to exist and it is difficult to monitor, but this probability is very low, and if there is, it will not be our Dongling City. You, stop thinking about it. Go and turn on the three switches numbered 7, 8 and 9 in the second row on the panel.

"Oh." Xiao Zhang scratched his head, came to the front of the control panel, and turned on the three switches according to the master's request. He asked curiously, "Master, these three switches seem to be the switches that release the interference signal equipment, right?"

"Yes." Lao Du nodded, "What you just said is not unreasonable, but in the face of this situation, there is nothing we can do. I can only add some ingredients to them. That's what it means. With that, there was a proud look on his face.

Speaking of the radio interference equipment in Dongling City, it has also won the provincial science and technology innovation award. Although it is more symbolic, at least it has won the provincial award, right? And Lao Du is one of the co-developers of these equipment.
