Since 1979 I have been in the tide of the times

Chapter 40 The Value of Brainwork

The old residential building of the teachers of Harbin Institute of Technology on Lianfa Street, Harbin City.

Professor Zhang, the deputy director of the radio department, was reading in the study when he heard a knock on the door.After waiting for a while, he heard footsteps, and it was his wife who went to open the door.

"Old Zhang, someone is looking for you!" My wife shouted outside.

Professor Zhang thought it was his student who came looking for him, but when he walked out of the study, he saw a man in his twenties with a big schoolbag on his back and looking at him with a smile.

"Are you a student of the University of Technology?" Professor Zhang asked.

"I am Wang Weidong, the director of the Entrepreneurship Radio Factory for the Disabled, and I am here to visit Professor Zhang today!" Wang Weidong said.

After Wang Weidong arrived in Harbin City, he rushed directly to Harbin Institute of Technology, found the teacher's residential area, and asked someone where the teacher of the radio department lived. Someone told him the house number of Professor Zhang's house.

Wang Weidong just emphasized the word "disabled".

"What's the matter with you?" Professor Zhang asked.

"Our Radio Factory for the Disabled produces radios. I'm here today to ask you if we can produce a radio that can listen to TV programs." Wang Weidong replied.

Professor Zhang felt that this question was a bit complicated, so he said, "Let's talk in the study."

After the two walked into the study and sat down, Professor Zhang asked, "Why do you want to produce radios that receive TV audio signals?"

"Our entrepreneurial radio factory now has [-] people, all of whom are disabled except me! Although they are disabled, they were good students when they went to elementary school and middle school, but because of their disabilities, they are not eligible to enter the university even after the college entrance examination is resumed! Now in the factory Several people signed up for TV University, and as the director of the factory, I decided without hesitation to buy a TV set for them to attend lectures with the factory's funds!" Wang Weidong said.

Hearing this, Professor Zhang nodded.

"Professor Zhang, think about it, how many people like them are there in our country! It's useless for them to be eager to learn. How many families can afford a TV now? So I want to produce a TV that can listen to their desire to learn. The radio for college classes!" Wang Weidong said.

"That's a good idea!" Professor Zhang said appreciatively.

"Is it difficult to produce such a radio? Is it expensive?" Wang Weidong asked.

"Nowadays radios generally use medium-wave and some listen to short-wave, but the frequency of TV signals is neither medium-wave nor short-wave. The frequency of TV signals is in the FM band, and it is in the FM band that is not often used." Professor Zhang replied.

"So it can't be produced or is it difficult to produce?" Wang Weidong asked.

"Of course it can be produced, but with the addition of frequency modulation, the cost of the radio will naturally increase." Professor Zhang replied.

"If it can be produced, then produce it!" Wang Weidong said.

He pressed his index finger on the table and said to Professor Zhang: "Professor Zhang, I just want to listen to the voice of Central Station, so that I can listen to TV University programs in the morning, and of course, I can also listen to the news at night. This can be done That's enough! Can it be simpler, just turn on the radio and listen to the program of Central Station?"

"The audio frequency of the channel is 56 megacycles. It is very simple to fix the frequency of the radio at this point." Professor Zhang said.

"The radio can listen to medium wave plus such a station! Professor Zhang, can you help us design a radio like this?" Wang Weidong begged.

"Of course no problem!" Professor Zhang replied.

"Just ask how much reward you want!" Wang Weidong said.

"This radio circuit is very simple. I can draw it tonight. You can pick it up tomorrow night." Professor Zhang said with a smile.

"Thank you very much! I have another question. Is there any art department in your university? I also want someone to help me design a radio casing." Wang Weidong said.

"We are an engineering university that does not engage in fine arts. You should go to HLJ Business School for this matter." Professor Zhang said.

Wang Weidong left with a thousand thanks.

Professor Zhang sat down and took out a blank piece of paper to draw a circuit diagram. His wife opened the door and stood at the door and said, "You who study satellite signals are now going to study radio."

"Didn't you hear that just now? The factory for the disabled, help if you can!" Professor Zhang replied.

The next night, Wang Weidong came to visit again. Professor Zhang took him into the study and took out the circuit diagram and said: "In order to reduce your production costs, I have made the circuit diagram as simple as possible. This radio has two frequency bands, AM and FM. , when you dial to FM, you can immediately listen to the central one without adjusting!"

"Professor Zhang, thank you so much! This is a very cheap radio produced by our factory, and I give it to you as a souvenir!" Wang Weidong took out a canvas suit radio from his big schoolbag and put it on the desk.

He stood up and bowed to thank Professor Zhang and left Professor Zhang's house with the circuit diagram.

After sending Wang Weidong away, Professor Zhang went back to the study and sat down to pick up the radio that Wang Weidong had given him. He opened the canvas bag and took out the radio that was half the size of a brick, and there was a stack of Great Unity inside.

He counted and there were 200 yuan!
Professor Zhang, who is nearly 50 years old, has participated in many national research missions and has never received so much money.This era is mainly based on spiritual encouragement.

"Weidong, you went to Harbin and exchanged 500 yuan for two pieces of paper?" Liu Jianguo asked.

"It's worth it, it's worth it!" Wang Weidong said.

After staying in Harbin for four or five days, Wang Weidong got a blueprint of a radio from Professor Zhang. He found a teacher who designed a logo in HLJ Business School and exchanged 300 yuan for a blueprint of a large radio.

Xiangyang Chemical Factory also has a lot of technicians, including several college students in their 60s and [-]s.They are just as qualified as ordinary workers to earn dead wages.

Even so, many workshop workers complained when they mentioned this matter, sitting comfortably in the office and writing without sweating to earn wages!

In this era, mental work is not as valuable as it will be in the future.

Wang Weidong exchanged 500 yuan for the two blueprints. Others didn't understand, even Shi Yueshuang couldn't fully understand.

Those technicians in the factory are his father's soldiers. They can do whatever they want, and are they still paid?Although the professors in the university are not Wang Weidong's soldiers, it's okay to pay a little, but isn't a few hundred too much for a shot?

"Weidong, you are so courageous, you dare to go directly to the professor of the university!" Shi Yueshuang exclaimed.

"Those people are very talkative. When I said that I work in a factory for the disabled, his attitude was very good. I will send him one of these radios when they are produced. If you want to keep in touch with such people, you will definitely have trouble in the future. People." Wang Weidong replied.

There is one sentence that Wang Weidong didn't say out of his mouth. He felt that it was easier to enter Professor Zhang's house than Fang's deputy director of Xiangyang Chemical Factory.
