Chapter 40 The Value of Mental Work

The old residential building of a Harbin Institute of Technology teacher 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 outside. After waiting for a while, he heard footsteps. It was his wife who opened the door.

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

Professor Zhang thought it was one of his students who was looking for him. When he walked out of the study, he saw a man in his twenties carrying a big schoolbag and looking at him with a smile.

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

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

After Wang Weidong arrived in Harbin, he rushed directly to Harbin Institute of Technology, found the teachers' residential area, and asked people where the teachers from 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 Disabled Persons Radio Factory produces radios. I am here today to ask you whether we can produce a radio that can listen to TV programs." Wang Weidong replied.

Professor Zhang felt that this issue was a bit complicated and said: "Let's go to the study room to talk."

After the two people walked into the study and sat down, Professor Zhang asked: "Why do you want to produce a radio that receives TV audio signals?"

"There are now eighteen people in our entrepreneurial radio factory, and except for me, they are all disabled! Although they are disabled, they were all good students when they were in elementary school and middle school. However, because of their disabilities, they are not eligible to take the college entrance examination even after the college entrance examination is resumed! Now in the factory

Several people signed up for the TV University, and as the factory director, I decided without hesitation to use the factory’s funds to buy a TV set for them to use for their lectures!” Wang Weidong said.

Professor Zhang nodded after hearing this.

"Professor Zhang, think about it, how many people like them are there in our country! It's useless for them to desire to study. How many families can afford a TV now? So I want to produce a TV that can listen to TV in order to satisfy their desire to learn.

Radio for college courses!" Wang Weidong said.

"This is a good idea!" Professor Zhang said with appreciation.

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

"Today's radios generally use medium wave, and some listen to shortwave. However, the frequency of the TV signal is neither medium wave nor shortwave. The frequency of the TV signal is in the FM band, and it is in the frequency modulation band that is not commonly used." Professor Zhang

replied.

"Does that mean 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 you can produce it, then produce it!" Wang Weidong said.

He put his index finger on the table and said to Professor Zhang: "Professor Zhang, I just want to listen to the sound of CCTV, so that I can listen to the TV University programs in the morning, and of course, I can also listen to the news in the evening. This can be done

That’s enough! Can it be simpler? Just turn on the radio and you can hear CCTV’s programs?”

"The audio frequency of the channel is 56.25 megacycles. It is very simple to fix the frequency of the radio at this point." Professor Zhang said.

"As long as the radio can listen to AM plus a station like this! Professor Zhang, can you help us design such a radio?" Wang Weidong begged.

"Of course, no problem!" Professor Zhang replied.

"Just ask for whatever payment you want!" Wang Weidong said.

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

"Thank you so much! I have another question. Are there any art students in your university? I also want to find someone to help me design the casing of a radio." Wang Weidong said.

"We are an engineering university and we don't have art students. You have to go to HLJ Business School for this matter," Professor Zhang said.

Wang Weidong left with great gratitude.

Professor Zhang sat down and took out a 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 radios."

"Didn't you hear just now? It's a factory for disabled people. If you can help, just help!" 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 made the circuit diagram as simple as possible. This radio has two frequency bands, AM and FM.

, when you dial the FM, you can hear CCTV immediately without having to adjust it!”

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

He stood up and bowed again to express his gratitude to Professor Zhang and then left Professor Zhang's home with the circuit diagram.

After seeing off Wang Weidong, Professor Zhang returned to the study and sat down to pick up the radio given by Wang Weidong. He opened the canvas bag and took out the half-brick radio and saw a stack of big unity inside.

He counted and found two hundred dollars!

Professor Zhang, who is nearly fifty years old, has participated in many national research tasks and has never received so much money. In this era, it is mainly about spiritual encouragement.

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

"It's worth it, so 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 trademark design teacher at HLJ Business School and exchanged it for 300 yuan for a blueprint of a large radio.

There are also many technical personnel in Xiangyang Chemical Plant, including several college students in the 1950s and 1960s. They earn a living wage just like ordinary workers.

Even so, many workshop workers still complain when it comes to this matter. They can sit comfortably in the office and write without sweating and earn wages!

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

Wang Weidong exchanged 500 yuan for two drawings. None of the others understood, not even Shi Yueshuang could fully understand.

The technicians in the factory were his father's soldiers. They could do whatever they asked, and would they be paid? Although the professors at the university were not Wang Weidong's soldiers, it was okay to pay them a little, but was it too much to pay them a few hundred?

?

"Weidong, you are so brave, you dare to go directly to the university professor!" Shi Yueshuang praised.

"Those people are very easy to talk to. When I told him that I was from a factory for disabled people, his attitude was very nice. Once this kind of radio was produced, I would send him one. If people like this keep in touch, they will definitely be in trouble in the future.

People." Wang Weidong replied.

There was one thing that Wang Weidong did not say. He felt that it was easier to enter Professor Zhang's house than to enter the house of Deputy Director Fang of Xiangyang Chemical Plant.
