Chapter 7: Voices from the Capital (Part II)

"Rustle... cqcq, here is by4bu calling cq and waiting for answer......"

The same call came again from the speakers, it was a man's voice.

Faced with this situation, Lin Hong was very surprised.

What's going on? Seems like there's a guy inside who keeps calling?

A movie clip suddenly appeared in Lin Hong's mind at this time. It was more than a year ago, and a film projection team came from outside the village, and in the evening a film on the Anti-Japanese War was screened in the farmland in front of the village chief's house. At that time, Lin Hong was sitting on his father's shoulder and watching, and he vaguely remembered that there was a soldier in the film who had a device with a long antenna on his back, and they used that device to get in touch with their partner.

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

Lin Hong completely remembered.

The reason why this memory is a little vague is because time has passed too long, and at that time, his brain is not very useful, a little groggy, and his memory is not as good as it is now.

"Rustle... cqcq, here is by4bu calling cq and waiting for answer......"

The other party kept repeating these words, as if he would not give up until he achieved his goal.

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

How do you answer that?

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

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

This should be the place to speak.

Lin Hong looked at the door of the room with some humility, but in the end he couldn't hold back, grabbed the microphone, plucked up the courage to use a trembling voice, and said weakly:

"Hey..."

"Rustle... cqcq, here is by4bu calling cq and waiting for answer......"

The other party still cried out tirelessly.

Lin Hong said a few more words, but the other party still didn't seem to hear it.

Is there a button here?

Lin Hong realized that there was a button next to the microphone, and he immediately understood that he should need to press this down when speaking.

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

When he finished saying this, the sound of the other party's constant shouting finally fell silent, and it didn't come out again for a long time.

Lin Hong's face showed a look of disappointment, and when he was about to hang the microphone back up, the voice in the speaker sounded again:

"Hello kid, it's a pleasure to set up a conversation with you...... Rustle rustle ......"

The other party actually answered!

Lin Hong's heart was pounding, blood was surging to his head, and his little face became red.

The experience of directly using the radio to talk to others made him feel very amazing. He had heard the teacher say before that there was a telephone in the next village, and he could talk directly to people thousands of miles away like face-to-face, so it was almost the same as this, right?

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

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

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

"Rustle... It's amazing that you can use the radio at the age of eight...... 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? ”

"Rustle... I'm in the capital, do you know the capital? It's where the ** is... Rustle......"

He turned out to be in the capital?!

Lin Hong was completely stunned.

The capital, where the ** is located.

In his impression, the capital is a very far and far city, 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 by train from Tanglin City to the capital. And now, he actually spoke directly to an uncle in the capital, which shocked him beyond measure.

"Rustle... Children, study hard, grow up, come to the capital to go to university, here...... Rustle-"

As the other party was talking, the sound of "rustling" 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 a "rustle" in the speaker, and he couldn't hear any sound clearly, 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 understand anything and was afraid of breaking the radio station.

In the end, he reluctantly hung up the microphone and left Lao Xutou's room.

Lin Hong, who was not in high spirits, said goodbye to the two old men who were playing chess outside, and walked home.

When he returned to his room, he lay on the bed, unable to calm down for a long time.

The experience just now gave him an unprecedented mental impact, he never imagined that through the radio, he could actually establish contact with people who were far away in the capital, and it felt like a face-to-face conversation.

Although he had heard similar scenes from his teachers, he didn't feel anything at all, thinking that it was too far away from him, and he was listening to it as a myth, but today he really felt the infinite charm of radio.

Capital......

Mom seems to be in the capital.

The picture of his mother came to his mind, and his eyes showed a deep sense of longing.

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

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

He began to make the "ore radio" in earnest, and the components he needed were taken directly from his small radio.

He knew very well in his heart that the "ore radio" was just a very simple radio, and it certainly could not be compared with the "radio station" of Lao Xu Tou. However, he still knows very little about radio now, and he must learn it step by step, so that he can finally make his own "radio station" like Lao Xu Tou.

The early geophone was made directly from natural ore, and the geophone is an important component in the radio, based on this principle, the existence of the "ore radio" is possible.

A simple ore radio has five main parts, a coil, a variable capacitor, a geophone, headphones and a ground and earth wire.

And the radio in Lin Hong's hand can directly extract some of the components, after all, he only has such a thing in his hand, and the other things either need to be made by himself, or he has to go outside to buy or pick up.

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

……

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

According to the magazine, the geophone can be made of ore and metal probes or replaced by a 2AP9 diode, but the diode is not as sensitive as natural ore.

Lin Hong didn't have either of these things on hand, but he finally decided not to replace them with diodes, because as mentioned in the book, the price of diodes is relatively expensive, and it is not something he can afford at present.

Preparing the main components, Lin Hong went out with the five 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, when he was in the nature class, the teacher of the school once said that some natural ores can be used in medicine. Moreover, he also saw it with his own eyes in the old Chinese medicine doctor.
