Chapter 209 The 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 brother. He seems to have gone to the laboratory building of the department. I don't know what laboratory it is. Why are you so anxious?"
There will be no classes at this time, Xue Shaohua I was reviewing in the dormitory with Qu Zhipeng. It was the end of the semester soon. Everyone was reviewing and preparing for the exam. I went to the library but there was no room, so I had to go back to the dormitory to review. The classroom was too empty and cold.
"Ask me to help you find 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 separated. Looking for it, Zhu Xuefeng happened to come out after finishing the test.
"Sixth, I have found you. Go to the department director's office and find Director Jiang."
…
In the department director's office, Director Jiang is entertaining guests. A middle-aged man is waiting anxiously for something.
"Old Huang, I've already gone to look for him. Now you should tell me what's going on. I have to find a first-year student."
"You'd better ask him about this. I was also attracted by him. "I called him."
Old Huang pointed at another middle-aged man with a wry smile. He was too shameless to say anything about this. Let Lao Chen do it. He is thick-skinned.
"Old Chen, I've seen you two here for a long time without saying anything. It's not appropriate."
"Actually, it's not that big of a deal. It's just you, the student, who did what he did. 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 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.
Currently, both Beijing and Shenzhou are researching and developing new transistor radios that are all domestically produced. They are all following the cooperation model of many electronics factories and research institutes.
After all, Shenshi has a foundation for success, and the current progress is better than that of Beijing. It is expected that the first generation of products will not be completed until the year after next. How can I let my first-year students make it? It is so easy, two The city is waiting for gifts. (September 1962, listed on the market after a gift from Shenshi Meiduo)
"Old Chen, don't lie. I am a student majoring in metal physics, not radio, and besides, I am a first-year student." The Institute of Applied Physics has teamed up with 774 and the Broadcasting Equipment Factory to conduct research and development. The current progress is behind Shenshi. Let alone a random freshman, he can do it. I can’t believe it, but there is a ready-made radio. Right in front of you.
The radio was also disassembled. Unfortunately, after the transistor used by Zhu Xuefeng was welded, in order to clean up the flux residue, after alcohol cleaning, the logo on the tube case was gone and could not be identified, so it was found later.
“Forget it, Lao Huang, take out the radio and let Director Jiang listen.”
Lao Huang opened his schoolbag and took out a radio that looked beautiful from a distance but rough up close. I turned on the small box and adjusted it a few times. Sure enough, I 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 1950s. The price quoted at that time was US$49.95. I just don’t know how much our little guy costs. We’ll have to wait and see. Ask."
"Report, Director Jiang, are you looking for me?"
The office was not closed. Zhu Xuefeng asked for instructions and faced Director Jiang directly.
"Classmate Zhu Xuefeng, you are here 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 Professor Chen from the Institute of Applied Physics. Leader Huang from the Broadcasting Equipment Factory is an acquaintance of Director Jiang, and he 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 principle 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 under the current conditions It can be made in seconds.
"The components of your product are all produced in Jingcheng? How much does one cost?"
"Most of the transistors in this are produced by Jingcheng Electronic Tube, and two of them are electronic There are two from the Fifth Factory and the Third Shenshi Radio Factory. The crystal oscillator is 707, the resistor and capacitor are 718, and some others are 798. 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, the old American’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, the new improved model is now only $14.95, and the effect has been improved a lot, the total is only about thirty-five yuan. "
Professor Chen didn't even know that there was an improved model, and it was cheaper. , asked quickly.
"Where did you read these data? Why don't we know?"
"This was read in our department library. It was brought back by our professor who returned to China. The latest "AWA" Introduced in "Comments"
"It seems that our information is very limited. We can't get the latest news. The cost is too high. The price of making one unit is the same as buying five units."
Two middle-aged men were asked by the cost, Prices and information have been hit one after another, which makes me a little depressed.
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 reason is that 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 80 million. This is the output of dozens of Beijing electron tube factories. You can imagine the scale of this company. , the cost will also decrease.
"Little comrade, we all know what you said, but now the country has no money, even the Beijing Electronic Tube Factory is a construction aid project."
"But lower the screening conditions and reduce the number of experimental projects It’s simple and easy to reduce costs and improve the pass rate, but give it a try.”
It was a bit of a mistake. I didn’t expect to ask Uncle Kong to hand it in. Without saying a word, I actually found the school. I have always adhered to it. Keep a low profile, I hope this radio doesn't cause uproar and uproar.
In the end, Zhu Xuefeng handed over the schematic diagram, circuit diagram and product design drawings. The two vowed to reward Zhu Xuefeng with one when the first batch is produced.
After seeing off the two experts, Zhu Xuefeng was about to leave, but was stopped by Director Jiang.
"Student 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 precious to this magazine of the Department of Physics."
