Restarting life in Siheyuan

Chapter 210 Radio is expected to be put into production

"Zhu Xuefeng, are Zhu Xuefeng here?"

The monitor ran back to the dormitory panting, opened the door and asked.

"Look for our sixth child. He seems to have gone to the department's laboratory building. I don't know what laboratory it is. Why are you so anxious?"

There are no classes at this time. Xue Shaohua and Qu Zhipeng are reviewing in the dormitory. The final is coming soon. Everyone is reviewing and preparing for the exam. They went to the library but there was no room, so they had to go back to the dormitory to review. The classroom was too empty and cold.

"Help me go look for him. Tell Director Jiang to look for him and ask him to go to the department director's office quickly. The three of us will look for him separately."

The three of them hurried to the laboratory building and searched separately. Zhu Xuefeng happened to come out after completing the test.

"Sixth, I have found you. Go to the department director's office and ask for Director Jiang."

...

In the department chair's office, Director Jiang was entertaining guests, and two middle-aged men were anxiously waiting for something.

"Old Huang, we've already gone to find him. Now you should tell me what happened. We have to find a first-year student."

"You'd better ask him about this. I was also called here by him."

Lao Huang smiled bitterly and pointed at another middle-aged man. He was too shameless to say anything about this. Let Lao Chen do it. He is thick-skinned.

"Old Chen, it's inappropriate to see you two here for a long time without saying anything."

"Actually, it's not that big of a deal. It's just your student who made a transistor medium-wave and short-wave dual-band radio."

"Someone sent it to us. The key thing is that the other party swore that the equipment in the radio was all made in China."

Director Jiang was confused for a while. As the head of the physics department, some information was quite clear.

The first transistor radio was successfully developed in Shenzhen City the year before last. However, all transistors were imported and could not be promoted, including the first car-mounted transistor radio, which also used imported devices.

Now, both Beijing and Shenzhen are researching and developing new transistor radios that are all made in China, following the model of cooperation between many electronics factories and research institutes.

After all, Shenshi has a foundation for success, and its current progress is better than that of Beijing. It is expected to complete the first-generation product the year after next. How can it be made by its first-year students? It is so easy. Both cities are waiting for gifts. . (September 1962, listed on the market after a gift from Shenshi Meiduo)
"Old Chen, don't lie to me. This student of mine majors in metal physics, not radio. Besides, I'm a first-year student."

Old Chen is obviously dumbfounded. I lied to you. You thought I was thinking that the Institute of Applied Physics, 774, and the Broadcasting Equipment Factory are working together on research and development. Now the progress is behind Shenshi. Let’s not talk about it. Just a random freshman. It was done. I couldn't believe it, but the ready-made radio was right in front of me.

The radio had also been disassembled. Unfortunately, after the transistor used by Zhu Xuefeng was welded, in order to clean up the flux residue, after cleaning with alcohol, the logo on the tube case was gone and it could not be identified, so he found it.

"Forget it, Lao Huang, take out the radio and let Director Jiang listen."

Lao Huang opened his schoolbag and took out a small box that looked beautiful from a distance but had a rough appearance up close. He turned on the switch and adjusted it a few times. Sure enough, he could actually receive the radio program and the effect was quite good.

"The first transistor radio in the United States was the TR-1 developed by Texas Instruments in the 49.95s. The price quoted at that time was US$[-]. I just don't know how much our little guy cost. I'll have to ask about it later."

"Report, Director Jiang, are you looking for me?"

The office was not closed. Zhu Xuefeng asked for instructions and then faced Director Jiang directly.

"Classmate Zhu Xuefeng, you came just in time. There are two comrades who want to talk to you. Let me introduce them to you." It turns out that the two middle-aged men are Professor Chen from the Institute of Applied Physics and Leader Huang from the Broadcasting Equipment Factory. , are all acquaintances of Director Jiang, and they came here for the radio.

Zhu Xuefeng had no choice but to introduce his design ideas and the specific circuit diagram of the transistor radio in detail. Zhu Xuefeng directly referred to the mature schematic diagrams of later generations, and the principles could be explained clearly.

The two nodded. Zhu Xuefeng's idea was obviously more reasonable than the circuits commonly used today. It cleverly avoided some technical difficulties, and the requirements for transistors have also changed a lot. No wonder it can be made under the current conditions.

"The components of your product are all produced in Beijing? How much does one cost?"

"Most of the transistors here are produced by Jingcheng Electronic Tube, two are from Electronics Factory No. 707, and two are from Shenshi Radio Factory No. 718. The crystal oscillator is from 798, the resistor and capacitor are from [-], and some others are from [-], the cost is about one hundred and sixty."

After all, the components were all chosen by himself. Zhu Xuefeng knew it very well. He said it without any hesitation, and the main sources were clearly stated. They were all made in China. The two of them were very happy to hear it, but when they heard the cost price, they suddenly A little bitter.

"It's so high. Lao America's own is less than fifty dollars, which is about 120 yuan, so we have no price advantage." (Exchange rate 1: 2.46)

"You are talking about TR-1, right? The new and improved model is now only $14.95, and the effect has also been improved a lot. The total is only about $35."

Professor Chen didn't know that there was an improved version and it was cheaper, so he asked quickly.

"Where did you see these data? Why don't we know?"

"I read this in our department library. It was brought back by our professor who returned to China. It was introduced in the latest "AWA Review"."

"It seems that our information is very limited. We can't get the latest news. The cost is too high. Making one unit costs the same as buying five units."

The two middle-aged men were frustrated by costs, prices and information.

During this period, foreign agencies also collected a large number of relevant newspapers, magazines, important documents and other materials. However, after all, the information was still blocked, and the exchange of information around the world was not smooth. It was normal not to be able to obtain relevant information.

"In fact, the cost can be reduced. Now, firstly, the qualification rate is relatively low, which leads to high costs. Secondly, the output is also low, and there is no scale effect, so the cost cannot be reduced."

"Another one, many of the selected tubes are produced for other special industries. The screening conditions and experiments far exceed the needs of civilian products. If some screening and experiments are reduced, the pass rate will be higher and the cost will be much lower. .”

Zhu Xuefeng finally caught people who were concerned about costs, and he couldn't wait to give some suggestions. Now the slogan of many special industries is "regardless of costs, ensuring success."

According to the latest news from the magazine, Xiaori is launching a large-scale transistor factory. It is said that the annual output will reach 8000 million. This is the output of dozens of Beijing electronic tube factories. As people scale up, you can imagine that the cost will decrease. .

"Little comrade, we all know what you are talking about, but now the country has no money, and even the Beijing Electronic Tube Factory is an aid project."

"However, it is simple and easy to lower the screening conditions and experimental projects to reduce costs and improve the pass rate. Let's give it a try."

It was a bit of a mistake. I didn't expect to ask Uncle Kong to hand it over. He actually found the school without saying a word. He had always kept a low profile and hoped that this radio would not cause uproar and uproar.

In the end, Zhu Xuefeng handed over the schematic diagram, circuit diagram and product design drawings. The two men vowed to reward Zhu Xuefeng with one when the first batch is produced.

After sending away the two experts, Zhu Xuefeng was about to leave, but was stopped by Director Jiang.

"Classmate Zhu Xuefeng, I really can't tell. Last time you said you liked radio, it seems you have put a lot of effort into it. You are very familiar with this magazine from the Department of Physics."
