Chapter 6 Voice from Beijing

A shabby magazine brought Lin Hong into another magical world. Only then did he find that there were so many invisible radio signals in the seemingly empty space. For the first time, I fundamentally understood the sound principle of the radio.

According to the magazine, the "ore radio" is very magical. It can listen to the radio station in the air without a power supply, and the components needed are also very simple, which is completely suitable for beginners.

Therefore, Lin Hong will make a "ore radio" as his latest goal.

Originally, as long as Lin Hong made it directly according to the instructions of the magazine, he didn't have to fully understand the principle at all. However, this is not what Lin Hong wants. His strong desire for knowledge will never allow him to do it so simply. He should fully understand the role of each of the originals.

So, he started his reading plan according to the list of reading books recommended by the author of the book.

The reading list includes six reference books. Lin Hong remembers them clearly. These six reference books are collected on Lao Xu's bookshelf.

During the day, Lin Hong sat upright in his seat. Although his eyes looked at the teacher on the podium, he was thinking about the content of the Simple Radio Principle.

At night, Lin Hong led Huang, one person and one dog quietly under the tree, and saw the dawn through the electric light of the car factory.

Five days later, Lin Hong had finished reading the book, and except for some of the knowledge he had not yet learned, he basically understood the content.

On Saturday again, Lin Hong came to Lao Xu's yard again. He was surprised to see that there was another old man in a big white coat in the yard today.

As soon as Lin Hong reached the door of the yard, the old man had already noticed that he looked at him from a distance, but Lin Hong felt that his scalp was numb, as if he had been suddenly stared at by some beast, and even felt a little difficult to breathe.

"General!"

Old Xu shouted, grabbed a chess piece with his right hand and patted it hard on the chessboard he drew with ink lines on the small table.

The old man's face changed, and he quickly moved his eyes to the chessboard, and found that he did not know that the little red horse that Lao Xutou jumped across the Chuhan River had formed a must-kill situation.

"It doesn't count! It doesn't count!"

The old man's voice was surprisingly loud and loud. He picked up the little red horse of the old Xu's head and retreated to the place, and he wanted to return to the move he had taken before.

Old Xu's happy face suddenly pulled down and quickly grabbed the old man's wrist:

"Old grandson, we agreed in advance that we should not cheat!"

"I was just distracted for a moment." The old man retorted, "It's all this boy's fault. If he hadn't suddenly appeared, I wouldn't have done such a stinky chess next, would I? Can't I see it after the horse cannon?"

After that, the old man looked at Lin Hong with a fierce face and stared at Lin Hong: "Kid, what are you doing here when you have nothing to do?"

"I...I..."

Lin Hong was scared by his momentum and stepped back half a step.

"All right, Mr. Sun, put away your behavior. I don't know you yet? Don't scare the child."

Old Xu's face showed helplessness. Obviously, he had already learned the tricks of this old grandson.

"Lin Hong, don't be afraid. This is Grandpa Sun from the next village. He is playing with you. Old Xu turned around and said to Lin Hong.

"Hello, Grandpa Sun, my name is Lin Hong." Lin Hong quickly said hello.

"Little guy, you are quite polite." Old Sun nodded with satisfaction, "Although he is smart, his personality is a little too feminine. Little guy, man, standing upright, walking, you should look up and straighten your chest, steel! Just like you just..."

"All right, all right, you talk too much." Old Xu quickly interrupted him. Old Sun didn't know Lin Hong's situation. If he didn't stop him, the straightforward old Sun would definitely hurt Lin Hong.

Then, Lao Xu asked Lin Hong, "Lin Hong, what's the matter with you coming here today?"

"Grandpa Xu, I've finished reading this book. Come and return it." Lin Hongyang raised the book in his hand, and then said, "In addition, I want to borrow a book to read it back."

Did you finish it so soon?

Old Xu was surprised, but he didn't say much, but said directly:

"Well, you can put the book directly back on the bookshelf. What book do you want to borrow? Go there to find it yourself. The door of the room is unlocked."

After saying that, he did it again, asked Lao Sun to continue to play chess, and finally agreed to the other party's regret chess under the other party's tricks.

Lin Hong saw that Lao Xu didn't have time to greet him, so he turned to Lao Xu's room.

Lao Sun looked at Lin Hongyuan's back, and then he understood why Lao Xu just interrupted his words.

"Is this child's legs and feet unfavorable?"

Lao Xu nodded and said, "He is a boy from Lin Changming's family. He had a brain injury when he was a child, but he left sequelae. It should have injured the cerebellum and the balance function was affected."

"Oh~" Old Sun suddenly said, "I remember that I heard that there was such a child in your village who broke his skull when he was a child and turned into a fool... Is that him?"

Old Xu shook his head and said, "He's just a little inconvenient for his legs and feet, and a fool can't..."

Speaking of this, Lao Xu remembered his contact with Lin Hong in the past few days and casually said, " Maybe he is the smartest of his peers."

Lin Hong came to Lao Xu's room, and this time he had a different feeling in his heart, because this time Lao Xu did not follow him, and his heart did not have the previous sense of restraint at all, and he felt very comfortable.

He first quickly walked to the bookshelf, opened Hebra, and then began to browse the books on the bookshelf from scratch again. This time was much slower than last time. He kept the name of each book deeply in his heart, just remembering the title of the book, because if he wanted to read it one by one, he would definitely not have time.

However, only those extremely professional book names also make him very excited, because these book names often include a lot of information, which greatly increases his vision.

For example, through the book "How to suppress the interference of electrical equipment to radio", he can know that electrical equipment has a negative effect on radio, and there have been experts and scholars who have done special research on this topic and found a way to deal with it.

Lin Hong's memory ability is very strong. Last time he just hurried through it, he seemed to have a virtual bookshelf in his mind. If he wants to know which book is in which position on the bookshelf, he just needs to think about it. It's just that last time because of time, he didn't finish it.

This time, it only took him about seven or eight minutes to complete the bookshelf in his mind.

Then, he took out a book called "Electrical Basics", which was a book mentioned by the author in the preface of his previous "Simple Radio Principles". The author said that if you want to fully understand the content of the book, you must first master the basic knowledge in "Electrician Basics".

Lin Hong opened "Electrical Basics" a little and was happy to find that this book is really the foundation of the foundation. It is specially prepared for those who do not have any electronic knowledge. Some common basic concepts and formulas are explained in it.

Lin Hong closed the book and was about to continue reading other books when a sudden "sand" sound came out of the room, which shocked him.

He heard the sound and saw that it came from Lao Xu's "radio station".

Before he walked to the front of the radio station, the sound came out of the speaker again, and this time it was no longer a noise, but a very clear voice.

"Shasha...CQCQ, this is BY4BU to call CQ and wait for an answer..."
