Chapter 63: Reversing the Future and Saving the World Amateur Radio Trans-Time and Space Communication Command

Let me explain this on two sides.

On the other side, in the Amateur Radio Trans-Space Communication Emergency Command Center for Reversing the Future to Save the World - this name was given by Bai Zhen, and the command center's office is located in Room 804, Building 11, Qinyuan, Meihua Villa, which is also the living room of his house. It sounds like an unprecedented organization, but in fact, there are only four people in total, a makeshift team among makeshift teams. My mom was forced to join in. My mom didn't know what tricks they were going to play and couldn't help much. My dad said that you will be responsible for the administrative work and will be appointed as the Executive Director!

My mom asked what administrative work is?

Dad said administrative work is serving tea, cleaning, purchasing office supplies, and taking meeting minutes.

My mother pointed and said, "Go and sweep the floor for me."

Dad said yes!

The Reverse the future, Save the world, Amateur radio and Hyperspace communications Emergency command was established in this way. Its English name is Reverse the future, Save the world, Amateur radio and Hyperspace communications Emergency command, and its English abbreviation RSAHE was also chosen by Walter White.

Old guy Bai Zhen has wanted to do this for a long time.

Who didn’t have a childhood dream of building a secret base?

Wang Ning looked at the long English name for a long time and asked Lao Bai, "Have you passed the CET-4?"

Bai Zhen asked what level four was?

It has been two days since Zhao Bowen left. During these two days, he has made 24 calls, an average of 12 calls a day, or one call in less than two hours. Sometimes Bai Yang would receive a call from Uncle Zhao at 11:30 at night, either asking him to take a picture of his ID card or to take a picture of the radio station. The most outrageous thing was that he was asked to clap his hands.

At 10:30 the night before yesterday, Bai Yang had just returned home and put down his schoolbag when he received a WeChat call from Uncle Zhao.

Zhao Bowen said excitedly on the other end that he had just finished a three-hour meeting, and with his eloquence and strong slaps, he finally convinced all the members present.

Bai Yang was shocked and asked, "What kind of meeting is it that can decide the outcome with a slap? Boboji National Technical Exchange Meeting?"

Lao Zhao said that in such occasions, what matters is who can slam the table louder.

If the sound of your banging on the table overwhelms the whole audience, then you are the boss.

Bai Yang said, "I thought everyone in that kind of occasion would sit like Shinji Ikari's father, Commander Ikari, with their glasses reflecting light."

Old Zhao said that these days there are not many older people suffering from the second-year syndrome.

Bai Yang said, "Okay, Uncle Zhao, what do you want from me? What photos do you want to take? What materials do you want to print?"

Lao Zhao said that it was not necessary, give me a round of applause!

Bai Yang was stunned.

Lao Zhao said that I finally managed to solve a difficult problem after going through so much hardship! I am now on the high-speed train to Hangzhou, ready to solve a difficult problem. I really want to stand up and shout to all the passengers in the train like a train salesperson, "Look here!" I solved a big problem! Everyone, give me a round of applause! But if I do this, I will probably be taken to the police station by the train police, so I can only call you, Yangyang, give me a round of applause!

Bai Yang put his phone on the table and clapped his hands.

Zhao Bowen hung up the phone contentedly.

Bai Yang stared at his phone blankly. This guy really came here just to ask for applause.

According to Lubianshe, on the evening of October 22, the third executive meeting of the Reverse the Future and Save the World Amateur Radio Trans-Time and Space Communication Emergency Command was held at Meihua Villa in Nanjing. Participants Bai Zhen, Wang Ning and Bai Yang had an in-depth discussion on the technical solution of using the Icom725 amateur radio station for data transmission, exchanged views and opinions on the feasibility of various technical paths, and reached a consensus.

"...In theory, the fact that you can get in touch proves that a communication link exists. She can receive the signals sent by your radio, and you can also receive the signals she sends, although we don't know how you do it." Before Wang Ning finished speaking, the phone in his pocket suddenly vibrated.

Everyone present focused their eyes on his phone.

"It must be Lao Zhao calling." Wang Ning said as he picked up the phone and glanced at the screen. It was an unfamiliar number.

He picked up the phone.

After a few seconds, his face changed. He put down his phone, covered the microphone, and whispered to the people in front of him: It's from Nanjing University.

Wang Ning trotted out to answer the phone. Bai Yang could hear his voice slipping in from outside the door: "Yes, yes... I'm Wang Ning... Hello, hello..."

Ten minutes later, Wang Ning came back after ending the call and sat down on the sofa.

"The people from Nanjing University came to inform us that they would come to our house at a certain time... We then said that since there is a communication link, it is technically possible to transmit other data. It is just a matter of modulation."

"What data?" Bai Yang asked.

"Any data." Bai Zhen said, "Modern communication engineering can hide anything into the carrier wave, just like when you use your mobile phone to browse videos and Weibo, the data exchange between you and the router is achieved through ultra-high frequency above 2GHZ, but its frequency is very high, it is UHF, while Guailiangwu uses shortwave, it is HF."

"That's a digital signal," Bai Yang said. "Two-five is an analog signal."

"Yes, that's a digital signal." Bai Zhen nodded. "I said, this is just a difference in modulation methods. At the most basic technical logic, your radio crystal oscillator emits high-frequency vibration energy, which is received by the other radio station through the antenna, causing its high-frequency vibration. It is no different from the transmission path of you hearing me speak, except that one is an electromagnetic wave and the other is a mechanical wave. When I was young, there were still large areas of China that used analog television signals. At that time, we used Yagi antennas to receive signals, and there was no problem with analog signals..."

Before Bai Zhen finished speaking, the phone on the sofa started vibrating.

"This time it must be Lao Zhao calling."

Bai Zhen glanced at the phone screen and saw an unfamiliar number.

He picked up the phone.

After a few seconds, his face changed, he covered the microphone of his mobile phone, and said to the other people who were whispering: It's the Municipal Party Committee calling.

Bai Zhen trotted out to answer the phone. Bai Yang could hear his voice slipping in from outside the door: "Oh, yes, yes, I'm Bai Zhen... Hello, hello..."

Ten minutes later, Bai Zhen came back from the call and sat down on the sofa.

"The people from the municipal party committee said they would also like to come over sometime. Let's continue. Analog signals are not a problem. Shortwave radio can transmit voice and images."

"If conditions permit, images can be transmitted." Wang Ning nodded. "Xiao Yang, do you know ARISS? It's the International Space Station. There is also an amateur radio station on the International Space Station, call sign NA1SS, usually operating on 145.800 MHZ. They have daily activities. In addition to communicating with the school, they also..."

Before he could finish his words, the phone rang again.

This time it was Bai Yang's cell phone that rang.

Bai Yang answered the phone: "Hello? Uncle Zhao?"

"Yangyang, they are all with you, right?" Zhao Bowen said on the phone, "Turn on speakerphone, loud speaker! Turn up the volume to maximum."

Bai Yang pressed the hands-free button and put the phone on the coffee table.

"I've dealt with another bunch of people! Damn, these idiots are so hard to deal with!" Zhao Bowen yelled on the other end of the phone, "But I'm so fucking tired! Where's the applause? Give me applause!"

The audience burst into applause.

Zhao Bowen hung up the phone contentedly.

He just came for applause.

Lao Wang said that he needs applause every day, so it would be a pity if Lao Zhao didn’t follow Brother Xiao to brainwash him.

"In addition to communicating with the sky and the earth, ARISS will also transmit some pictures." Wang Ning continued, "It can be received by anyone with the most basic equipment."

"All walkie-talkies can receive it," Bai Zhen said, "as long as you get a suitable antenna."

"This is a very basic technology. Xiao Yang, you must have heard of it." Wang Ning said, "Slow scan TV, we usually call it..."

"SSTV." Bai Zhen said.

"Think of a way, maybe we can do it." Wang Ning looked up at Bai Yang and grinned, "Let you two meet each other."
