According to the plan, Chen Zhaojun began to guide his eldest brother Chen Zhaoping to install the radio. Thanks to the logistical support of the communications company of the military headquarters, the rest is much simpler. If you are missing any parts, you can just go to the communication company to find them.

Chen Zhaojun first worked with Chen Zhaoping to make a single-tube radio. In fact, it is said that the two studied together, but it is better to say that Chen Zhaojun first designed the circuit diagram according to the book, deliberately made a few mistakes, and then asked Chen Zhaoping to carve the circuit board himself. This is mainly to cultivate Chen Zhaoping's interest and hands-on ability. Of course, the reason is also very good, I am still young, and I can't come into contact with more dangerous things such as sulfuric acid. Of course, Chen Zhaoping was very interested, after all, he was "inventing" by himself. The next situation is of course obvious, after a few busy days, what is pretended will not ring. Chen Zhaojun made a very disappointed look, threw away his things, and didn't care about anything. Chen Zhaoping didn't do it, for this radio, he was busy for several days, and when he saw that he was dressed, but it couldn't sound, of course he was not convinced. In order to make the radio ring, Chen Zhaoping kept rummaging through the information and checking everywhere. Chen Zhaojun watched from the side and remained silent. For the next few days, Chen Zhaoping was busy with his radio. In order to figure out what the problem is, Chen Zhaoping must figure out the circuit part, figure out the circuit, and he must also understand the principle of coordination between all the devices, so that he needs to calculate the interrelationship between the devices so that they can achieve the most ideal effect.

In this way, Chen Zhaojun used a simple single-tube radio to force Chen Zhaoping to start a comprehensive review of physics and mathematics in middle school.

About a week later, Chen Zhaojun and Chen Zhaoping discovered the problem at the same time, so Chen Zhaoping installed the first radio that sounded. Why did it find out at the same time, because Chen Zhaojun still has the next plan.

On this day, Chen Zhaoping took the single-tube radio he had installed and did not even have a casing to go around the world to invite people to listen to the radio. Infected by Chen Zhaoping, the children in the compound began a heat wave of installing radios. Of course, Chen Zhaoping has become the leader here, either guiding this or helping that every day, and he is very busy. But he also enjoyed it very much. The most important thing is that Chen Zhaoping has completely understood the principle of single-tube radio, so helping others is simply familiar.

Chen Zhaojun saw all this, in order to stimulate Chen Zhaoping, Chen Zhaojun installed a double-tube radio himself when his eldest brother was busy instructing others to install single-tube radios, these things, for Chen Zhaojun, are simple things. I think that in order to have fun, Chen Zhaojun installed a walkie-talkie with his classmates when he was in junior high school, but as long as the computer was turned on, the whole unit could not watch TV. With this foundation, installing a double-barreled radio is just a piece of cake.

That afternoon, Chen Zhaoping instructed others to come back after most of the day, and in the living room of the house, he was shocked to find his younger brother Chen Zhaojun adjusting a radio that he had never seen before. This took him by surprise. All along, he thought that the last monotube radio was made by himself. Because he's spending a lot of energy on that. But I didn't expect that when I came home today, I saw my younger brother debugging a double-pipe radio, although there was still a bit of noise, but no matter from the perspective of technology or technology, I didn't say that my single-pipe radio could be compared.

"Third child, what are you doing here?" Chen Zhaoping became interested. With the experience of installing monotube radios, Chen Zhaoping became interested in these things.

"It's a twin-tube radio with an extra level of preamp amplification and harmony, which makes the radio quality better." Chen Zhaojun didn't say anything else to his eldest brother, he understood that it was useless to say anything now, so it was better to wait and let the eldest brother study it himself.

After a little adjustment, Chen Zhaojun put down the things in his hand: "It's adjusted, how about it?" In fact, before Chen Zhaoping came back, Chen Zhaojun had already adjusted the radio, and now it is just a look.

"It's not bad, you go read your book, big brother come and take a look." Chen Zhaoping unceremoniously drove Chen Zhaojun away, occupied his place, and studied Chen Zhaojun's double-pipe radio.

In order to make Chen Zhaoping easier to understand, Chen Zhaojun specially drew a circuit diagram and put it on the table, but in order to be more helpful to Chen Zhaoping. I deliberately drew two wrong places. In Chen Zhaojun's opinion, this can be regarded as an exam for Chen Zhaoping.

Compared with the things in hand, Chen Zhaoping studied for a long time. He understood the working principle, but he couldn't understand why the design drawings drawn by his brother looked like there was a problem?

For the sake of insurance, Chen Zhaoping began to analyze one route after another, and it didn't take long for him to discover the key to the problem.

"Zhaojun, there is a problem with your circuit map, and you drew it wrong."

Hearing Chen Zhaoping's words, Chen Zhaojun smiled, he was busy for a month or two, and finally it had an effect, and the eldest brother's understanding of electronic circuits had reached a new level. It looks like it's time to move on to the next step.

"I drew it by hand, it's not interesting, I'm going to install a multi-tube radio, what do you say?" Chen Zhaojun knows that installing a radio has now become the best toy for Chen Zhaoping, and as long as he says it, he will definitely follow it.

"Wow, wow, let's do it together. Install a radio that's even better than the movie team's radio. Chen Zhaoping is now the leader of the entire compound to install radios, and in order to ensure that his entire position is not threatened, of course he has to install a radio with a little bit of energy. Later, Chen Zhaoping found out that in order to install a radio, he had systematically studied physics and mathematics in middle school.

In fact, it is not only Chen Zhaoping who has benefited, after the children in the compound began to install radios, fewer people went out to make trouble every day, and more people read and studied. This saved a lot of worry for the parents in the compound. It also made the Chen brothers more famous. Even with Chen Zhaoguang, the second eldest member of the Chen family, seeing his brother and younger brother busy studying and experimenting every day, he gradually became more attentive to his studies, and his grades ranked first in the class.

。。。。。。

After another month or two, Chen Zhaoping's seven-tube radio was installed, and the effect was really good. However, this also made Chen Zhaoping change a little. Because this radio can hear Taiwan's "Voice of Freedom" radio station and "*". In that era of extreme lack of information, these more alternative things became the favorite things of Chen Zhaoping's group of young people, and a group of classmates closed the door every day, hiding at home and listening to the radio.

Chen Zhaojun didn't pay attention at first, but when he found out that the situation was getting worse, he began to worry. You must know that at that time, these two radio stations were both called "enemy stations," and listening to their broadcasts was a big or small thing, but if they were put on the platform, they would become counter-revolutionaries in the current situation. Chen Zhaojun knew that he had to come up with a way to divert the attention of his eldest brother and a group of classmates so as not to cause problems.

But how do you achieve something that is both interesting to them and helpful to their learning? It's a real headache.

That night, after Chen Weixiong came back, he habitually put the gun on the ground again, disassembled it, and cleaned and wiped it one by one. When Chen Zhaojun saw Chen Weixiong's gun arranged in parts, a brilliant idea made him excited.

There is no child who grew up in the army who doesn't like guns, and there is no one who doesn't like to fiddle with guns. Basically, any weapon, these kids will love it. I can start from this convenience, and I believe that I will definitely be able to attract Chen Zhaoping's attention back. Of course, Chen Zhaojun knew that it couldn't be too difficult at first. It's too hard for anyone to play. There has to be a simpler way. What Zhang Guimei said some time ago about fried fish appeared in Chen Zhaojun's mind again. Make your own zha medicine! Nothing is simpler, and it can let Chen Zhaoping and them learn some chemical knowledge.
