However, complaining is complaining, as the captain, he can't embarrass his comrades, so he practiced the technique of radio listening with peace of mind.

At the beginning, the training is relatively simple, the instructor will make you close your eyes and then play a louder sound, which has a corresponding scene, such as a bus, such as a train station. There are all kinds of sounds inside.

The menopause female instructor said that a headset was buckled on my head, after which a recording was played.

After I listened to it, I frowned, and said what is this, messy, the whole background sound seems to be a mahjong parlor, there are all kinds of mahjong sounds, there are shuffling sounds, there are the sound of throwing dice, there are Sichuan women scolding and scolding. The whole audio is not very long, about 20 seconds or so.

The instructor turned off the machine and asked me, "What did the smoker say?" ”

Damn, there are at least 4 men's voices in the whole recording, and I fucking know which uncle it is, or the uncle who smokes. I said I didn't hear it, so she played it back to me.

I still didn't hear it this time, and then I started a third time.

The third time, I listened as carefully as I could, only to hear one of the young men say, "Eat spicy chicken tonight." There was also an older man who shouted: "Tianzi A table is missing one of the three." There was also a scolding street that seemed to be muttering, which uncle was smoking a cigarette and saying something.

After three times, there was still no progress, and the instructor became a little impatient, pinched his waist, pinched his orchid finger and began to count me.

"Listen to me carefully, there are so many students, I can't consume them one by one, listen carefully! There's an old man smoking, come again! ”

I was busy with a smile on my face: "Auntie, oh no, instructor, what's that, I'll listen to it myself a few times first, you go to other people's places to see, hehe, I'm a little stupid, I have to take my time." ”

The instructor glared at me, and after a long time, I went to Brother Lei, and I sweated for Brother Lei again, and said Brother Lei, you should be smart. There's nothing going to do to help you.

Unexpectedly, Lei Ge actually passed in one go, and the instructor asked him, how many shots did the pistol fire in the whole audio? Brother Lei immediately replied, 4 shots, and then the instructor left Brother Lei's desk satisfied, and Brother Lei gave me a thumbs up.

I shrunk my neck, and said in my heart that I still want to worry about others, I am hanging myself, Brother Lei has this talent, much stronger than me. So I sat upright and listened intently to the headphones.

Seven times in the local area, I suddenly faintly heard the sound of an old-fashioned lighter opening the lid, accompanied by the sound of mahjong, the lighter was thrown on the table, and then a voice said: "Touch! ”

I slapped the table and jumped up, laughing loudly, in the quiet classroom, it seemed extremely abrupt, Sally who was standing at the door with the class was startled, and everyone looked at me strangely.

I didn't notice it at all, it was like secretly listening to the single play with headphones during a high school self-study class, and the same table slapped you, and you said loudly: "What are you doing!" At this time, I happened to be caught by the teacher, and I excitedly called: "I found the smoking uncle, and he said, "Touch!" He said "touch"! ”

Sally hurriedly gestured to me to calm me down, signaled the instructor to come, I took off the headphones, looked back, and sure enough, the whole team of students looked at me like a psychopath, and the instructor also walked towards me with an angry face.

I quickly sat down awkwardly, and the instructor said, "How many times have you listened to it?" ”

I stretched out my thumb and forefinger and whispered, "Eight times."

"Are you so happy eight times?"

I stopped talking, and the players laughed loudly, as if they were quite happy to see the captain deflated. I asked the instructor: "Instructor, now that technology is so advanced, can you explain why you still need to learn such an old-fashioned technology?" ”

The instructor looked at me, then at everyone, motioned for everyone to take off their headphones, then cleared their throats and explained.

It turns out that with the development of science and technology, the old-fashioned radio station has been eliminated, and only in the case of underdeveloped short-wave communication will the old-fashioned radio station be used, such as border posts, train locomotives, fishing boats, and now this band is basically played by some radio enthusiasts, and national communications and intelligence exchanges have long been without this way. So there are intelligence systems that take advantage of this loophole and use this old-fashioned way to transmit intelligence.

In addition, this old-fashioned communication system has his stability. This is something that some modern technologies can't match. For example, today's North American Air Defense Command not only has a developed network command system, but also has a radio system in case of emergency. That's it.

And this way of intercepting information often requires a pair of very sensitive ears, in the noisy radio wave sound, keenly find the radio wave you want to listen to, which is the classic Didi Di Di sound.

It dawned on me that if you want to be a James Bond, you really have to be proficient in everything.

So I stopped being verbose and concentrated on practicing.

To say that I am really not a hard worker, but I have found that if I am not hardworking, this level is very difficult. So outside of the normal classroom, I always use my extracurricular time to practice this skill.

At the beginning, I went to practice with the audio materials of the training session, and then I asked for a large semiconductor with the logistics, and deliberately dismantled the resistance coil a few times, or stripped the insulating paint on it, so that the effect of the entire radio would be very poor.

I tried it, and found that the broken terrain where the school is located cannot receive any long-wave signal at all, as mentioned above, the school is located in the depths of the mountains in the hinterland of China, and Mr. Li Bai, a member of the Tang Dynasty Writers Association, also wrote "Shu Dao Difficult" to describe. There are thousands of mountains in the mountains, and there will be no communication long waves that will travel here.

For the sake of confidentiality, the school can't access the Internet, and I have listened to those so-called listening materials all over again, what should I do?

At this time, Sally gave me an idea to go to the top of the mountain, and the top of the mountain might receive some signals. As soon as I heard that it was a good idea, I asked Panzi to modify my semiconductors and make a very exaggerated antenna.

I told Lei Zi that when I exercised in the morning, let him help organize it. I woke up an hour early, carried my bulky semiconductor, and ran down the repaired steps to the top of the hill to try to connect my ears.

The next morning, I picked up the semiconductors, took the antenna, and set off. Sit on the platform at the top of the hill and listen carefully to all the radio waves that can be received.

After nearly 2 weeks of training like this, I have made great progress, and it seems that talent can be improved through practice.

But during one of the exercises, I heard a special signal that aroused my suspicions.
