Chapter 7 Voice from Beijing

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

The same call came from the speaker again, which was a man's voice.

In the face of this situation, Lin Hong was very surprised.

What's going on? It seems that there is a person calling inside?

A movie clip suddenly appeared in Lin Hong's mind. More than a year ago, there was a film screening team outside the village, and in the evening, an anti-Japanese war film was shown in the farmland in front of the village chief's yard. At that time, Lin Hong was sitting on his father's shoulder. He vaguely remembered that there was a soldier's device with a long antenna on his back in the film, and they used that device to get in touch with his partners.

Yes, the equipment they use is called a radio station!

Lin Hong completely remembered it.

The reason why this memory is a little vague is that it has been too long, and at that time, his brain was not very easy to use, a little drowsy, and his memory could not be remembered at a glance like now.

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

The other party is constantly repeating such words, as if he won't give up until he reaches his goal.

And there seemed to be a special magic in the voice. Lin Hong felt that he was a little ready to move in his heart, and he always had an impulse to respond.

How to change the answer?

Lin Hong's eyes swept around on the device in front of him.

At this time, he saw an oval thing hanging on the radio panel in front of him, and a wire connected to the inside of the radio station at the tail.

This should be the place to speak.

Lin Hong looked at the door of the room humbly, but finally couldn't help it. As soon as he grasped the microphone, he summoned up the courage to say weakly in a trembling voice:

"Hey..."

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

The other party is still calling like this tirelessly.

Lin Hong "fed" a few more words, and the other party still seemed not to hear it.

Is there a button here?

Only then did Lin Hong find that there was a button next to the microphone, and he immediately understood that he needed to press this when talking.

So, he pressed the button and summoned up his courage again and said, "Hey...Hello..."

When he finished saying this, the voice of the other party's continuous calls finally fell silent and did not come out for a long time.

Lin Hong's face showed disappointment. When he was about to hang the microphone back in place, the voice in the speaker sounded again:

"Hello, child, it's a pleasure to establish a call with you... Shashasha..."

The other party actually answered!

Lin Hong's heart pounded, his blood rushed straight to his head, and his little face turned red.

The experience of talking to others directly on the radio makes him feel very wonderful. He heard from the teacher before that there is a phone in the next village where you can talk directly to people thousands of miles away face to face. It's almost like this, right?

Under the shock, he was so excited that he couldn't speak for a long time.

"Shasha...child, how old are you?" The other party took the initiative to ask.

"I... I'm eight years old." Lin Hong finally replied.

"Sasha... I can use the radio station at the age of eight. It's amazing... My uncle didn't know anything when he was eight years old..."

Lin Hong took the initiative to ask a question this time: "Uncle... Where are you?"

"Shasha... I'm in Beijing, do you know Beijing? It's where Chairman Mao is... Shasha..."

He turned out to be in Beijing?!

Lin Hong was completely stunned.

Beijing, where Chairman Mao is.

In his impression, Beijing is a very far, very far city, just like a star in the sky, which is out of reach.

The teacher once said that it takes at least a few days and nights to get there from Dongling City to Beijing. And now, he is talking directly to an uncle in Beijing, which makes him shocked.

"Shasha...children, study hard, grow up, come to Beijing to go to university, here... Shasha--"

As the other party was saying, the voice of "Shasha" suddenly became louder, directly covering the other party's voice.

"Hey, uncle, are you there?"

Lin Hong hurriedly called a few words, but there was still "shasha" in the speaker. He couldn't hear any sound at all, and he completely lost contact with the other party.

Looking at so many knobs on the panel, Lin Hong didn't dare to operate it at all, because he didn't know anything and was afraid of breaking the radio station.

Finally, he reluctantly hung up the microphone and left Lao Xu's room.

Lin Hong was not very interested. He said goodbye to the two old men who were playing chess outside and walked home.

After returning to his room, he lay in ** and couldn't calm down for a long time.

The experience just gave him an unprecedented spiritual impact. He never thought that he could connect with people far away in Beijing through the radio, and it felt like a face-to-face conversation.

Although he had heard similar scenes from the teacher, he didn't feel anything at all at that time. He thought that the situation was too far away from him and was listening to it as a mythical story, and today he really felt the infinite charm of the radio.

Beijing......

Mom seems to be in Beijing.

The photo of his mother came to his mind, and there was a strong thought in his eyes.

If I also have such a radio station, can I talk to my mother like this?

Thinking of this, Lin Hong immediately got up, then took out the radio broken by his father from the "treasure chest" under the bed, and then took out a knife from the box.

He officially began to make "ore radios", and the components he needed were directly sourced from his own small radio.

He knows very well that the "ore radio" is just a very simple radio, which can't be compared with Lao Xu's "radio station". However, he still knows very little about radio, and he has to learn from the simple step by step before he can finally make his own "radio station" like Lao Xu.

The early detector is made directly from natural ore, and the detector is an important component of the radio. Based on this principle, the existence of "ore radio" is made possible.

A simple ore radio, the main components are five parts, a coil, a variable capacitor, a detector, headphones and a heaven and earth wire.

And the radio in Lin Hong's hand can directly extract some of the components. After all, he only has one thing in his hand. Otherwise, he needs to make it himself, or he has to go outside to buy or pick it up.

After extracting a few components from it, he came to his father's room, found a bundle of enameled thread from a large box, then found a beer bottle thrown by his father in the yard, and began to wrap the enameled thread around the beer bottle.

......

Although Lin Hong's hands-on ability is very strong, the "ore radio" can't be completed for a while, mainly because he does not have the most important component "wave detector" at hand.

According to the magazine, the detector can be made of ore and metal probe by itself, or replaced by 2AP9 diodes, but the sensitivity of the diode is not as good as that of natural ores.

Lin Hong didn't have these two things on hand, but he finally decided not to replace them with diodes, because the book mentioned that the price of diodes is relatively expensive, which is not what he can afford at present.

Preparing the main components, Lin Hong went out with the previous 50 cents in his arms. He knew that an old Chinese medicine doctor in the village had the so-called "green ore" to buy. He remembered that during the nature class, the school teacher once said that some natural ores could be used as medicine. Moreover, he also saw it with his own eyes at the old traditional Chinese medicine doctor.
