Bai Zirui said with a serious face: "Yes! These people in our courtyard are not fuel-efficient lamps. After letting them know about our affairs, there is no guarantee that they will not be jealous if they offer to take a share of the pie.

We are all neighbors. Do you agree or reject? If you agree, they are all selfish people. They will end up bleeding their heads for a small profit, and don't make the city full of trouble.

If you reject them, they will be jealous and report us for opportunism. In short, these people in the courtyard are not doing well for me, so you can’t think of being better than me."

When He Yuzhu heard what Bai Zirui said, he thought about the virtues of the people in the courtyard, especially his rival Xu Damao, who was just a despicable villain with sores on his head and pus on his feet.

If it was true as Bai Zirui said, he couldn't guarantee it to others, but Xu Damao would definitely report the two brothers.

It seems that what they want to do must be hidden from the people in the hospital. Once they know about it, the consequences will be disastrous.

He vowed: "Zirui, don't worry! I will wander around our area in the next two days and I will definitely find a safe place for you to assemble your bicycle and radio."

When the two brothers returned to the courtyard, He Yuzhu brought him back from the canteen and heated up the food. After the two brothers ate, they took a rest.

When he arrived at the recycling bin at work the next day, Bai Zirui collected the broken radios from the recycling bin, which he considered to be old antiques, and dismantled them one by one to check the cause of the damage.

After seeing Bai Zirui's actions, others gathered around him. Feng Zixuan said jokingly: "Zirui, don't you want to tinker with the radio again? This is a high-tech thing. Do you know how to repair it?"

Bai Zirui smiled mysteriously and said, "Webmaster, you'll find out later."

With the matter of assembling bicycles in front of him, everyone watched with suspicion as he tinkered with the broken radios.

The principle of the radio is to detect (demodulate) the high-frequency signal received from the antenna and restore it to an audio signal, and then send it to the earphones to become sound waves.

Radios in the 1970s were very simple tube radios, and most of the casings were made of wood.

The red 711-5 tube radio he is dismantling and repairing is the last model of the 711 series of radios developed and produced by Shanghai Radio Factory No. 2 in the 1970s.

The workmanship is excellent, the shape is generous and regular, and the whole radio looks very stable.

The entire casing is made of wood, the front frame is inlaid with aluminum strips, and the frequency indication part is made of a whole strip of glass painted on the back.

The red lantern pattern will light up when the phone is turned on, and the light will shine through the entire scale glass from the side of the frequency scale glass at the same time. It has the same principle as the backlight of the LCD screen. Unfortunately, it is broken now and makes no sound. Because there were relatively few people who knew how to repair radios at that time.

, had to be sold to the recycling bin by the owner.

The top, bottom, left and right sides of the machine casing are made of a single piece of wood, but the back panel is made of pressed wood chips. There is a groove in the bottom panel, and there is a part protruding from the bottom of the back panel, which just fits into the groove of the bottom panel. Just remove the back panel

Pull up to remove the back panel.

The moment Bai Zirui opened the back panel, he smelled the smell inside the case, and suddenly felt the atmosphere of people's living conditions in this era. There were many empty spaces in the case, and the power cords and short-wave antennas could be stored in the case.

He began to examine electronic devices such as air variable capacitors, medium-wave magnetic rod antennas, power transformers, resistors, capacitors, etc.

He checked that all the electronic components were fine, and finally found that the speaker wire was broken. After re-soldering the speaker wire, he installed the battery and turned on the radio, and a "sizzling" noise began to come out.

He adjusted the direction of the antenna and adjusted two frequencies. A melodious voice came from the radio: "Xinhua News Agency reports..."

The others were a little disbelieving when they heard the sound coming from the radio. After they reacted, they could be said to be close to him, and they were astonished to him.

Feng Zixuan even more excitedly patted his shoulder and said, "Zirui, I really belong to you."

Bai Zirui assembled the repaired radio and put it aside. Several other people squatted nearby and listened happily to the radio. He then began to inspect and repair other broken radios.

Some of these radios had resistors, capacitors were broken, or soldered wires fell off. Fortunately, there were available electronic parts to replace them. He repaired five radios in two hours of work.

Feng Zixuan looked at the five radios that Bai Zirui had repaired, and they happened to have one for each of them. He announced on the spot that these five radios would be used as welfare for each person in the recycling bin. This made Bai Zirui very popular in the recycling bin.

Everyone else happily took their assigned radios home when they got off work. Bai Zirui took his own radio back to the courtyard with a calm expression.

After Yan Bugui saw it, he immediately stepped forward and asked: "Zirui, where did you get this radio? Can I go to your place to listen to the radio in the future?"

Bai Zirui replied: "I bought a second-hand radio. I just started working and I don't have that much money to buy a radio. This is because someone moved and it was inconvenient to carry it. The ones we collected from the recycling station can be used for a while."

Third uncle, you can listen if you want! How about giving you a monthly subscription for thirty cents?"

Yan Bugui said: "Zirui, we are all neighbors, why do you have the nerve to accept money?"

Bai Zirui said: "Third uncle, I learned this from you. If you don't have enough to eat, you won't have to suffer from poverty. If you don't calculate it, you will suffer from poverty!"

Bai Zirui said that Yan Bugui was speechless and walked inside. Yan Bugui looked at his back and spat: "Bah! Why are you so pretentious? It's just a broken radio! I'll buy a new one tomorrow.

Go, who cares about your second-hand broken radio?"

After He Yuzhu got off work, he heard people in the courtyard talking about the radio that Bai Zirui had brought back, so he came to his ancestral home and asked him: "Zi Rui, is this the finished radio?"

Bai Zirui nodded and said, "Yes! Brother, if you like it, you can take me to your room and listen."

He Yuzhu waved his hands repeatedly and said: "No... no need! Don't let me, a big guy, break such a precious thing."

Bai Zirui curled his lips and said, "What's so valuable about a radio? This thing is so simple, it's not as good as your gramophone, brother! How about we exchange it."

He Yuzhu said hurriedly: "That won't work! It was something given to me by the senior leader. It is very commemorative to me."

While the two brothers were talking, Wu Guohao came to the courtyard. Bai Zirui stood up and welcomed him into the room. He poured him a cup of tea and asked, "Brother-in-law, you are a busy man. Why do you have time to come here today?"

Wu Guohao took a sip of tea and said: "Zi Rui, the case of Banggeng theft that you reported a few days ago has been closed. The court will officially make a judgment tomorrow. Am I here to return your design drawings?"

As Wu Guohao spoke, he took out the design drawings, put them on the table and pushed them to Bai Zirui. He put the design drawings away and said politely: "It's just such a small matter, why bother my brother-in-law to come to my place? You guys will inform me

Just tell me and I will go to the police station to get it."

Wu Guohao waved his hand and said: "This is all something that can be done with a little effort. I came over to take a look. You just arrived in the capital from Beidahuang. Is there anything else you need help with?"
