On the other side, in Reversing the Future and Saving the World, the Emergency Headquarters of Amateur Radio Time-Space Communication¡ªthe name was given by Bai Zhenqi, and the headquarter¡¯s office is located in Room 804, Building 11, Qinyuan, in Meihua Villa, which is the living room of his house. It sounds like an ancient and modern organization, but in fact there are only number four people in total, the grass team in the grass team, my mother was forced to come in, I don't know what they are going to do, and I can't help, Dad said that you will be in charge of administrative work, and he will make you the administrative director!
Mom asked what is administrative work?
Dad said that administrative work is serving tea and water, cleaning, purchasing office supplies, and keeping meeting minutes.
Mom pointed and said to sweep the floor for me.
Dad said yes!
Reversing the Future and Saving the World Amateur Radio Hyperspace Communications Emergency Command was established in this way, referred to as the Reverse World Command, the English name is reverse the future, save the world, amateur radio and hyperspace communications emergency mand, the English abbreviation is rsahe, and it is also taken by Lao Bai. .
This old boy Bai Zhen has long wanted to do this.
Who didn't have the dream of building a secret base when they were young?
Wang Ning stared at the lengthy English name for a long time, and asked Lao Bai, have you passed CET-4?
Bai Zhen asked what is the fourth grade?
It has been two days since Zhao Bowen left. During these two days, he has made 24 phone calls, an average of 12 calls a day, and one call in less than two hours. Sometimes Bai Yang can answer it at 11:30 in the evening. Uncle Zhao's phone calls either asked him to take pictures of his ID card, or asked him to take pictures of the radio station, and the most outrageous ones asked him to slap his hands.
The night before yesterday at 10:30, 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. With his sharp tongue and thick slaps, he finally convinced all the members in the meeting.
Bai Yang was shocked and said, what is the meeting that can decide the winner with a slap? **A national technology exchange meeting?
Lao Zhao said that in this kind of occasion, the comparison is actually about who slaps the table loudly.
If the movement of you slapping the table crushes the audience, then you are the boss.
Bai Yang said that I thought everyone would sit in the same posture as Shinji Ikari and his father Commander Ikari on that occasion, and the glasses still reflect light.
Lao Zhao said that these days there are not many old middle school diseases.
Bai Yang said okay, Uncle Zhao, what do you want to do with me? What photo? What material to print?
Lao Zhao said no need, give me a round of applause!
Bai Yang was taken aback.
Lao Zhao said that I have finally gnawed a hard bone after going through untold hardships! I'm sitting on the high-speed train to Hangzhou now, and I'm about to gnaw a hard bone. I really want to stand up like a train salesman and yell at all the passengers in the car to show me! I solved a big problem! Give me a round of applause! But if you do this, you may be turned over by the police and sent to the police station, so I can only call you, Yang Yang applauds me!
Bai Yang put the phone on the table and applauded loudly.
Zhao Bowen hung up the phone contentedly.
Bai Yang stared blankly at the phone, this person really came to ask for applause.

According to Lubian News, on the evening of October 22, the third executive meeting of the Emergency Headquarters for Reversing the Future and Saving the World¡¯s Amateur Radio Overtime and Space Communication was held in Meihua Villa, Nanjing. I725 amateur radio station for data transmission technical scheme, exchanged views and opinions on the feasibility of various technical paths, and reached a consensus.
"Theoretically speaking, if you can get in touch, it proves that there is a communication link. She can receive the signal transmitted by your Guai Er Wu, and you can receive the signal sent by her, although we don't know how to do it. We're here." Before Wang Ning finished speaking, the cell phone in his pocket suddenly vibrated.
All the people present focused their attention on his mobile phone.
"It must be Lao Zhao calling." Wang Ning picked up the phone as he spoke, and glanced at the screen, seeing an unfamiliar number.
He took it.
A few seconds later, his expression changed, he put down his phone to cover the microphone, and whispered to the people in front of him: "NTU is calling."
Wang Ning trotted out to answer the phone, Bai Yang could hear his voice slipping in from the door: "That's right I'm Wang Ning Hello, hello"
Ten minutes later, Wang Ning came back from the call and sat down on the sofa.
"The people from Nantah University, they came to inform, saying that they would find a time to come to the door I??Going on to say that since there is a communication link, it is technically possible to transmit other data, and it is nothing more than a modulation problem. "
"What data?" Bai Yang asked.
"Any data." Bai Zhen said, "Modern communication engineering can hide anything into the carrier wave, just like you usually use your mobile phone, surf the Internet and browse Weibo, and the data exchange with the router is through UHF above 2GHz It is realized, but its frequency is very high, it is uhf, and the short wave is used for turning two to five, it is hf.¡±
"That's a digital signal." Bai Yang said, "It's an analog signal."
"Yes, that's a digital signal." Bai Zhen nodded, "As I said, it's just the difference in the modulation method. At the lowest level of technical logic, your radio crystal oscillator emits high-frequency vibration energy, which is transmitted through the antenna. The other party's radio station received it, causing its high-frequency vibration, which is no different from the way you hear me speak, except that one is electromagnetic waves and the other is mechanical waves. When I was young, there were still large areas of China that used analog signals. TV, at that time, the Yagi antenna was used to receive the signal, and there was no problem with the analog signal"
Before Bai Zhen finished speaking, the phone on the sofa vibrated.
"This time it must be Lao Zhao calling."
Bai Zhen glanced at the screen of the phone, seeing an unfamiliar number.
He took it.
After a few seconds, his face changed, he covered the microphone of the mobile phone, and said to other soft-spoken people: The municipal party committee is calling.
Bai Zhen trotted out to answer the phone, Bai Yang could hear his voice slipping in from outside the door: "Ah, yes, yes, I am Bai Zhen hello, hello"
Ten minutes later, Bai Zhen came back from the call and sat down on the sofa.
"People from the municipal party committee said that they should come over sometime. Let's continue to say that analog signals are not a problem, and short-wave radio stations can transmit voice and image."
"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. The call sign is na1ss. They are usually active on the Internet. They have a daily event. , in addition to communicating with the school, they will also"
Before he finished speaking, the phone rang again.
This time it was Bai Yang's cell phone that rang.
Bai Yang answered the phone: "Hello? Uncle Zhao?"
"Yang Yang, are they all by your side?" Zhao Bowen said on the phone, "Turn on the speakerphone and put it on! Turn the volume to the maximum."
Bai Yang pressed the hands-free button and put the phone on the coffee table.
"I've dealt with another group of people! Damn, this group of **** people are hard to beat!" Zhao Bowen yelled on the phone, "But I'm so fucking exhausted! Where's the applause? Give me applause! "
The audience applauded thunderously.
Zhao Bowen hung up the phone contentedly.
"Ariss will also send a few pictures in addition to engaging in the world communication." Wang Ning continued, "It can be received with the most basic equipment, and anyone can receive it."
"The walkie-talkie can be received." 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 meet each other." </div>
