"The following is the National Anti-Japanese War speech delivered by Mr. Jiang Zhongzheng, Chairman of the Military Commission of the Nationalist Government..."
Before people started to arrive, Han Cheng turned on a semiconductor radio and listened to the Nationalist Government's broadcast. In fact, there was a radio in Yan'an, but the broadcast was always broken. If you wanted to listen, you still had to listen to the Nationalist Government's broadcast.
"It's him again. This is bad luck. I thought there would be Peking Opera today."
"Isn't this what happened in Kuomintang-controlled areas now? Let's play Peking Opera music, play some anti-war speeches, and introduce anti-war heroes. I'm tired of listening to them."
The gay man who came early said helplessly.
"Didn't I introduce a contemporary Hua Mulan a few days ago, a fourteen-year-old girl joining the army? Why don't you believe me today?"
"I guess the little girl is dead. What a temptation it would be to have a woman in the army. Besides, this happened more than once. A few months ago, a female student joined the national army as a soldier and was killed within a few days.
The officer did nothing, and then the female student committed suicide. We had done publicity before, but then nothing happened. This is the modern Mulan. Every one of us found dead."
As for the reason, Han Cheng didn't have to think about anything else. According to the military discipline of the national army, what good thing could it be to be in such a group of people?
"There is no way, the world is like this. Those who survive are all luck, and those who do not survive are fate. You say you don't believe in fate, but in this time of danger, you have to believe in something, so that you can have some confidence and some hope in your heart."
Han Cheng connected one end of the radio, and then used tools to skillfully dismantle the radio, completely revealing the structure inside to everyone. At this time, the people had almost arrived, and Han Cheng looked at the few people sitting in front of him.
, these people are both male and female.
"As for the radio, to put it bluntly, it is also a transmitter, but it can only receive frequencies and cannot send out signals. You may come to me because you want to learn how to make a radio. My radio is not difficult, and the antenna is not necessary
.As long as you find a few radios, you can make one yourself. Mineral radios are not suitable because they contain too few electronic components and do not meet the requirements."
Han Cheng removed the shell and found that there was a skeleton inside, and all the electronic components were revealed.
"The speaker you have been listening to is this big magnet. This is the thing that makes the sound. This thing can be used or not. If you don't want to use it, you can connect a small light bulb here. The small light bulb will turn on or off according to the sound. If
If you stop talking, the little light bulb will naturally go out."
"As for the earphones, you need to remove the earphones of an ore radio. The ore radio is actually used for the same reason as a semiconductor radio. They are both used for detection and listening. However, because the ore is a semiconductor, its performance is still somewhat poor, so the listening
The sound is very low, you need to add a pair of headphones.”
"This is the place to adjust the frequency. Generally, there is no need to change this place, because what we send and listen to are shortwave stations, and the frequencies are the same. You can adjust it yourself in detail."
As for the internal structure, why did Han Cheng tell them so carefully? These people have a temperament that is different from his own. Especially the calluses on the index fingers. They are not obtained by hard work. They are gun calluses.
The commander has it on his hand, and the battalion commander also has it on his hand.
This must be a secret mission. Anyway, you wouldn’t expect a woman to appear on an ordinary mission. This must be a latent mission. The conditions for transporting the radio from the base are too harsh, even very difficult. Self-made radios are used in special situations.
Region is a very good way.
"I'll spell it out for you. Then you can connect it like this. You must remember that if the order in between is wrong, it will be completely useless."
Han Cheng taught carefully here. Anyway, they will learn it later. At least now they have just made a beginning. Anyway, it will only take about ten days. After getting these done for them, they will be
graduated.
"Look at these things for yourselves, and then remember how to connect them. Basically, the order is almost the same. I will explain the key parts to you after you have memorized the order."
Although these people here are knowledgeable and educated, they don't know much about physics, and some may know very little. The only way to do this is to let them memorize the structure by rote, and then talk about the parts one by one.
.
In fact, this is not difficult for ordinary people, but it may be more difficult for those who have no basic knowledge. For example, remember the sequence and the densely connected wires in the middle.
"Comrade Han Cheng, is this a little too complicated for you?"
"My dear comrades, this is the simplest one, and it is not a large radio station for you to do. This is the first small radio station with a wide range of sources. You only need to find a suitable radio to do it.
Come out. Second, the power required is low, you can connect it to the power supply, or even directly connect it to the car's battery for power supply."
This thing is actually very troublesome to make, but there is no way, this is already the simplest structure. All the structures inside have not been modified, the only modification is to pull down the wires again.
"This is what you need to remember. You must make sure you don't make a mistake. Once you make a mistake, the entire radio will be ruined.
Han Cheng basically told them all the things they need to pay attention to, and the rest is up to them. How much they can learn, and whether they can pick up the radio on their own in the end, all depends on the situation.
While they were looking at the circuit, Han Cheng was doing manual work. Yesterday's metal was all turned into a big lump. It was not poured into the mold at all and was all stuck to the crucible. Han Cheng heated it again at night to melt the metal.
Everything is made into the shape it should be, and you can just trim it slowly when the time comes.
In fact, the sniper rifle type can still follow the French post-war modification method. After all, it is a gun used in the Vietnam War, and it is already very mature in terms of performance. However, there are no composite materials at this time, and it can only be made of tung oil.
Soaked wood is used to replace the corresponding composite materials. Because there are still many things that were added to the design later, some of which are unnecessary, so some designs need to adapt to the current war, and more of them are cost considerations.
The barrel requires special processing, so Han Cheng spent a lot of effort to drill a straight hole in the processing of the barrel. As rare metals are added, the hardness of the barrel increases linearly.
.Because the barrel and the handguard cannot be in direct contact, some fixed points need to be added in the middle to connect the handguard and the barrel. Everything is built according to the requirements of a sniper rifle, which is much more refined than the one from Little Japan.
