Restarting life in Siheyuan

Chapter 181: Get the handheld components

Using the resources of the Department of Physics, the radio has been made. I haven't thought about which department to hand it over to. The key is that the cost is too high. It uses nine triodes and one diode.

There are more than 40 other resistors, capacitors, inductors and other components in total. The cost alone is more than [-]. It is enough to replace a bicycle. This price cannot be promoted.

The sound quality is good, it can be driven by ordinary batteries, and the size is relatively suitable. The casing is also processed by myself in the factory of the Department of Physics. I really learned this craftsmanship in vain, and I made all the small accessories myself.

The pass rate of transistors at this time was too low, resulting in extremely high costs. Zhu Xuefeng had some ideas to improve the pass rate, but there was no way. Besides, who would believe the advice of a first-year freshman majoring in metal physics?

With Uncle Kong's letter of introduction, I made two trips to the Jingcheng Electronic Tube Factory (the predecessor of BOE) in Jiuxianqiao. The current electronic tube factory has an annual output of one million diodes and [-] transistors. It is currently the largest transistor manufacturer in the East. .

After picking and choosing among countless products with substandard parameters, I collected a dozen of the missing three types of transistors. It was all about luck. I also bought all the others. I was pretty lucky with the materials for the walkie-talkie. Finally, I picked one out of a thousand. Got four sets together.

This factory's current products are for military use, HT, and HK. If it weren't for Uncle Kong's letter of introduction, we wouldn't even be able to get in. The tubes that were finally selected from the scraps were not even confiscated and they said they had been scrapped. Procedure, charging any more money would be against the rules, but it saved Zhu Xuefeng a lot.

"Uncle Zhang, next time you help me keep something with this kind of parameters, I think it won't be long before there's a demand for it."

Uncle Zhang was the technical person in charge who accompanied Zhu Xuefeng in the selection process. Without him organizing people to help, Zhu Xuefeng would not have been able to complete the parameter testing of so many tubes.

"Okay, I'll keep them all for you. If you can really use them, it's better than scrapping them. The transistor is much more expensive than the electron tube. It would be a pity to scrap it."

"If we really need to use it, these parameters are still a bit off. Let's talk about it then. It will be a matter of time before the transistor replaces the electron tube. Just wait and get busy. Uncle Zhang, I'm leaving. Thank you very much."

The production of electronic tubes in the electronic tube factory has not stopped, and it still accounts for the majority of the factory's production tasks.

With the various equipment and resources of the Physics Department, it is not a big problem to make it, but the batteries used for the walkie-talkies cannot be obtained.

The battery required for the transmitting unit has high requirements for volume, voltage, and power. There is no such battery in China now. This is directly related to signal transmission and cannot be replaced at all. If the power supply is used instead, this handheld radio will be meaningless and become a radio station. .

Zhu Xuefeng processed the copper-clad laminate into a single-sided printed board. He simply assembled it first, debugged it in the laboratory, and experimented twice with the laboratory's DC power supply before waiting for the battery.

Chief Lu has been entrusted to help contact the chemical factory. There is no hope for this thing in the near future. The chemical factory has not even completed the upgrade of lead-acid batteries. This technology is more difficult, so we can only wait.

In the following days, Zhu Xuefeng spent his extracurricular time on campus either continuing to study ductile iron or studying Cantonese with Fang Jiaming.

The notice above stated that in view of the difficulties in recent years and the decline in students' physical fitness, the school's twice-annual sports meets were canceled, as was the reason for canceling the annual long-distance race around the city.

At noon on Saturday, squad leader Chen Jun came to the dormitory to inform.

"According to the education plan and the needs of rural farming, the first-year students from the Department of Physics will be assigned to work in Qinghe for a week next Monday to participate in the autumn rice harvest."

"At that time, everyone will have to bring their personal supplies and stay in the village for a week. I will also have to notify other dormitories."

The dormitory suddenly became lively. It had been more than a month since school started, and most people had only left the school on the day of the parade. Now they were very happy to be able to return to their hometown.

Today is Saturday, and next Monday is October 17th. I have to go and participate in military training again, and it will be the end of November or the beginning of December when I come back. Many things still need to be arranged.

"I'm good at harvesting rice. I do it twice a year. It's really rare that there is still rice in the north. What's it like now?"

This is Chen Zhihe, who comes from a land of plenty and rice. He must have harvested a lot of rice. "Have you not seen the Summer Palace? You can't understand why there is rice in the north. You, the life committee member, don't have enough common sense about life. Let's remove him."

After chatting with a few people, they found that Qu Zhipeng, Zhang Yong, Xu Dapeng, and Xue Shaohua had harvested rice. Only Zhou Jidong, Zhu Xuefeng, and Fang Jiaming had not been in contact with them.

...

Zhu Xuefeng and Xia Yuhong were on their way home. It seemed that Foreign Languages ​​and Literature had also been notified of production labor. Xia Yuhong was also very excited. They were also harvesting crops, but they were not in the physics department.

Junior high school and high school students were organized to go to the countryside to work in the countryside, but they never got any rice. They usually helped weed and water in nearby villages. Other villagers did not dare to let their children do it. This would be terrible. The harvest is gone.

Xia Yuhong blinked her big eyes and said very seriously.

"Xue Feng, you won't accept it, right? Let's find someone to teach you, otherwise everyone will laugh."

Xia Yuhong is very strong and doesn't want to show her timidity in front of her classmates. She actually wants to learn to harvest rice.

"It's very difficult to find someone to teach you how to harvest rice in a northern city. You don't have enough time. It only takes one day. Besides, if you go to the fields, the villagers will definitely teach you. Don't worry, just be careful not to cut yourself."

"You just cut yourself. Who could be as stupid as you and dare to say that I..."

...

"Brother Zhuzi, I have to ask your help for something. I may be out from next week to early December, so I may not be able to take care of it."

"What's the matter? Just tell me and don't bother me with it."

Silly Zhu leaned against the door frame lazily, carelessly.

This is Silly Zhu’s daily image. I have been reminded several times. It was only a few days after the last blind date that it changed back. Fortunately, after my sister went to college, she also knew that there should be some changes. At least her current clothes are A lot tidier.

"I am going to work in production next week, and I have to go to military training next month. I will definitely not be able to make sauerkraut in time. I will clean out the kimchi jar tomorrow. You have to help me pickle the sauerkraut, and I also need to help me look after the Chinese cabbage stored in the winter. point."

"Leave it to me no matter how big the problem is. I guarantee that it will be marinated for you so that the color is right and the taste is sour. You can just pick it up. I have to marinate it too. We will do it together when the time comes."

"The street office will organize the winter storage, so don't worry about it. Just bring it back and I'll help clean it up."

"Then thank you Brother Zhuzhu. I'll let the two little guys give you a try when the time comes."

In the winter in the north, there are really not many vegetables, just radishes, cabbage, and some dried vegetables. Some families have some conditions, and they will prepare some eggplants, melons, potatoes, and peppers in advance in the autumn, which are not easy to spoil. of stored.

You can start pickling sauerkraut in October. In early November or at the latest in mid-November, there must be organized winter storage of Chinese cabbage, and each family has a quota. These are the main dishes in winter.

　It is a fact that students are organized to harvest rice. This is the course arrangement and the location is real. There is no need to question the rice harvesting in the north.
