The secret war is silent

Lao Chi, you can work with peace of mind. If you need anything, just tell me directly. I will handle the messy things outside. Luo Yao said solemnly.

clear.

Chi An knows how difficult it is to meet a good boss. If a person is capable, but if he meets an unreliable superior, he may not be able to achieve any big results in his life.

But if it is someone who understands him and strongly supports him behind his back, then this person can burst out with unparalleled energy.

Are there enough people?

Right now, there are just three of us, Jia Bingwen and Wu Yulang. We are really busy. It would be best if we could increase the manpower.

Do you have any familiar introductions? Luo Yao said, I'll go get them.

Everyone I know works in other departments, so I guess they won't come here. Lao Jia and Xiao Wu should know people. I'll ask later and introduce them if they are suitable.

Okay, introduce me. The salary and benefits are the same as theirs, but there are some restrictions on freedom of movement. After all, our job is different from other jobs. Luo Yao said.

clear.

Go and do your work, I'll just take a look myself.

OK.

Luo Yao walked all the way to the mailroom. After adding ten new express machines, the place became bloated. At a glance, at least seven or eight machines were open.

As the director of the mailroom, Wen Xueren is instructing the new trainees to practice on the aircraft and intercept Japan's coded communications. The current main direction is the Japanese Army's coded communications, the Japanese Air Force's communications, the Ministry of Foreign Affairs' coded communications, and Navy ships. Ship communications, temporarily on hold.

Firstly, the mountain city is located in the hinterland of China, and the electromagnetic signal is attenuated. This is not the best place to monitor these two types of secret communications. Secondly, the students are still in the starting stage. Although they are making rapid progress, there is still some way to meet the qualification requirements. Gotta go.

You can't start running before you learn to walk, right?

Webmaster, you're here. When Wen Xueren arrived here, he felt like a duck in water. There was no one to disturb him. He could listen to whatever he wanted, and his salary was twice as high as before. He could still live freely. Importantly, Yes, in just twenty days, he actually gained ten pounds.

She used to be thin and weak, looking like she would collapse if the wind blew, but now she is much better.

And as soon as he arrived, his military rank was promoted one level.

Even if the Telecommunications Department invited him back with double the salary, he would not go back. He is depressed and unhappy at work in one place. Is the money given useful? Isn't it possible that they might find an excuse to fire you at any time? Also, do they really want to invite him back?

Not just to learn from his mouth how the secret research team deciphered the Japanese Air Force's secret code.

You guys are busy, I just took a look. Luo Yao himself often sends and receives newspapers, and his hearing is even more abnormal, but he rarely shows it now.

Except for those close to him, outsiders really don't know that his hearing is not inferior to Wen Xueren's, and is even much better than Wen Xueren's.

Webmaster, I have something to report to you. Wen Xueren asked the students to continue working and invited Luo Yao into his office next door.

Luo Yao came in and took a look. Wen Xueren's office was simply a small mailing and receiving room. In addition to his own desk and a hardwood sofa for guests, the small office also had a workbench that occupied one-third of the space. Three transceivers and various telecommunications equipment were placed.

In addition to sending and receiving telegrams and listening to these electromagnetic signals with mysterious information, Wen Xueren also likes to tinker with various telecommunications equipment.

In the words of later generations, this person should be a radio enthusiast.

Wen Xueren didn't regard Luo Yao as an outsider. He generally knew that Luo Yao also knew technology and was his boss, so there was no need to hide anything from him.

Webmaster, listen. Wen Xueren handed Luo Yao a pair of headphones and asked him to put them on, then took a cassette tape, put it on the cassette player, and turned the play button.

Didi...

The sound of the radio wave was very short, less than a minute before and after, but the person who sent the message was very fast and steady. When he heard it, he thought he was a veteran with at least three years of experience in sending messages.

The transmission was very coherent and done in one go.

Webmaster, please continue listening! Luo Yao raised his eyes and looked at Wen Xueren, expressing his confusion as to what he meant by letting himself listen to this radio wave.

Luo Yao did not take off his earphones, but continued to listen. After a while, another radio wave appeared in his ears, and the time was also short.

But as soon as it appeared, Luo Yao judged that it was coming from the same person.

Wen Xueren did not press the pause button, so Luo Yao continued to listen. There were seven such radio sounds recorded on this tape. The longest was only three minutes, and the shortest was only thirty seconds. They were all made by the same person. telegraph.

Webmaster, I accidentally listened to this radio signal half a month ago. Because it was so clear, there was almost no attenuation in the signal, and I had never heard it before, so I recorded it. Later, I The same signal was intercepted at the same time. This radio station transmits at a very regular time, once every other day, usually between 9:30 and 10 o'clock in the evening... Wen Xueren intercepted the signal and studied it. It's been a while.

This is the telegram I intercepted, with the time, frequency, and call sign marked on it. Wen Xueren took out a stack of manuscript paper from the drawer and handed it to Luo Yaodao.

Luo Yao looked through it, and with his memory, he naturally recognized it at a glance. This was the number of the radio signal he just heard.

Do you have an idea?

Webmaster, I judge that the user of this secret radio station is a radio operator with at least three years of work experience. Moreover, his workload is extremely heavy to develop such fast hand speed. The most important thing is, According to my analysis of the signal, the signal is very clear and the attenuation is almost negligible. I judge that the radio signal is somewhere near us. Wen Xueren said.

scope?

About twenty kilometers.

Twenty kilometers away, it's hard to find. There are many unregistered private radio stations in the mountain city, let alone those secret radio stations. Your range is too large to find, and you can be sure that he is a Japanese spy. A secret underground radio station? Luo Yao asked.

No, but this signal is very suspicious.

Such a secret radio station uses a special code book and cannot be deciphered without a key. I think you must have tried to decipher the various Japanese military communication codes currently available, right? Luo Yao asked.

Wen Xueren smiled coquettishly: I tried it, but the donkey's head is not as good as the horse's mouth.

Luo Yao nodded. If there was a real investigation, it would cost countless manpower and material resources, and there might not be an exact result.

This kind of radio signal discovered accidentally is like a lucky break, there is no telling.

Webmaster, I actually want to ask you to help me listen to another recording of the radio signal. Wen Xueren chuckled. Why would he invite Luo Yao to his office if he was not prepared at all.

Just because he discovered a mysterious radio signal that turned out to be of no use in the end, he still reported it in a serious manner. Wasn't that making him feel uncomfortable?

besides?

You'll understand after listening to it.

Wen Xueren took out another tape and put it into the player. Then he motioned to Luo Yao to put on the headphones again and unscrew the play button.

A very normal transmission was transmitted into Luo Yao's ears from the earphones. After listening carefully, Luo Yao frowned slightly.

Wen Xueren did not interrupt and waited until Luo Yao finished listening to the entire tape before turning off the player.

Stationmaster, what did you hear?

Xiao Wen, these messages seem to be sent clearly. The first one is from Shancheng to Yudu, and the second one is from Shancheng to Xiangcheng...

That's right, webmaster, these are all clear messages, and they were sent by the Shancheng Telegraph Office. Wen Xueren said.

Why are you monitoring the transmission of other people's telegraph offices? Luo Yao asked strangely, although he knew that some people like to do things that are difficult for ordinary people to understand.

Wen Xueren smiled shyly: I sometimes work the night shift and I really can't sleep during the day, so I like to listen to this 'tick-tick-tick' sound to fall asleep.

Luo Yao smiled and said that it was understandable. One of the husband and wife snored, and they were used to it. Suddenly one day, there were so many cases where they couldn't sleep without hearing the snoring.

Webmaster, don't you think that although the hand speeds of sending these two different messages are different, their methods are similar? Wen Xueren continued.

You mean, when two 'dots' are sent in a row, the second dot is lighter than the first dot. When the number '4' is sent, four 'dots' are sent out continuously without any pause in between. , this is very consistent with the four consecutive 'dots' I heard before, and we can basically assume that this may be the work of the same person. Luo Yao analyzed.

Listen to it again. A joyful smile broke out on Wen Xueren's face, and he immediately turned the tape back manually, put it up again, and pressed the play button.

Luo Yao was actually basically sure that this was a message sent by the same person, and it was also the same machine, but in order to cooperate with Wen Xueren, he put on his headphones again and listened to it again.

Then I listened to the previous telegram from beginning to end.

You want to say that the telegrams in these two tapes were sent by the same person and the same machine, right? Luo Yao took off his earphones and gave the answer directly.

The stationmaster is right. This person works at the telegraph office and takes advantage of the night shift to send messages privately, and also deliberately speeds up. Once a person's sending speed is established, it rarely changes, especially when Telegraph operators who work in the telegraph office have developed a physical instinct over many years. It is not impossible to speed up, but it is difficult, and it is even more difficult to ensure that there are no mistakes in the process of speeding up. Wen Xueren explained excitedly.

Xiao Wen, I understand what you mean. Don't tell anyone about this matter. I will investigate. If it has nothing to do with Japanese spies, then it is an ordinary case of self-inflicted theft. Just hand it over to the police station directly. Luo Yao He ordered solemnly.

clear.

Intuitively, Wen Xueren's unintentional discovery may cause quite a stir in the mountain city.

On the last day of January, please continue asking for monthly votes!
