Chapter 45 Repairing the Radio

Bai Zirui said with a serious face: "That's right! These people in our courtyard are not easy-going lamps. After letting them know about our affairs, it's hard to guarantee that they won't be jealous. If they offer to share a piece of the pie.

We are all neighbors, do you agree or reject?If they agree, they are all selfish people, and they will be beaten to death for a little profit at that time, and the city will be full of storms at that time.

If you reject them, they will report us for speculating with jealousy. In short, these people in the courtyard are not doing well for me, so don't think about living better than me. "

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

If it's what Bai Zirui said, he can't guarantee it for others, but Xu Damao will definitely report the two brothers.

It seems that these things they are going to do must be hidden from those people in the courtyard. Once they know the consequences will be unimaginable.

He said solemnly: "Zi Rui, don't worry! I've been walking around our area for the past two days. I will definitely find a safe place for you to assemble your bicycle and radio."

The two brothers returned to the courtyard, and He Yuzhu brought him back from the cafeteria to warm up the food, and the two of them rested after eating.

When he came to the recycling bin at work the next day, Bai Zirui collected the broken radios in the recycling bin. In his opinion, they were all broken radios of the old antique level, and he took them apart one by one to check the cause of the damage.

After seeing Bai Zirui's actions, the others gathered around him, Feng Zixuan jokingly said: "Zirui, don't you want to tinker with the radio again? It's a high-tech thing. Could it be that you can also repair it?"

Bai Zirui smiled mysteriously and said, "Station Master, you'll find out after a while."

With the matter of assembling the bicycles ahead, everyone watched him tinkering with these broken radios in doubt.

The principle of the radio is to restore the high-frequency signal received from the antenna into an audio signal through detection (demodulation), and send it to the earphone to become a sound wave.

The radios in the 70s were very simple tube radios, and most of the shells were made of wood.

The red 711-5 electronic tube radio he is disassembling and repairing is the last of the 70 series radios developed and produced by Shanghai Radio No. 711 Factory in the [-]s.

The workmanship is excellent, the shape is generous, and the rules are quite satisfactory. The whole radio looks very stable.

The entire case 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 it 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, which is the same principle as the backlight of the LCD screen, but unfortunately it is broken now and cannot make any sound.Since there were relatively few people who knew how to repair radios at that time, they had to be sold by the owner into the recycling bin.

The top, bottom, left, and right of the machine shell are made of a whole piece of wood, but the backboard is made of pressed wood chips.There is a groove on the bottom plate, and a part protrudes from the bottom of the back plate, which just fits into the groove of the bottom plate.Just pull the back panel up to remove the back panel.

The moment Bai Zirui opened the back panel, he smelled the smell inside the case, and immediately felt the atmosphere of people's living conditions in this era.There is a lot of space in the case, and the power cord and shortwave antenna can be stored in the case.

He began to check electronic components such as air variable capacitors, medium-wave magnetic rod antennas, power transformers, resistors, and capacitors.

He checked all the electronic components and found that the speaker cable was broken. After re-soldering the speaker cable, he installed the battery and turned on the radio, only to hear a "sizzling" noise.

He adjusted the antenna in one direction and two more frequencies, and a melodious voice came out from the radio: "Xinhua News Agency reports...."

The others couldn't believe it when they heard the sound of the broadcast from the radio, but after they realized it, they could be said to stick close to him, which was a shock to him.

Feng Zixuan patted him on the shoulder excitedly and said, "Zirui, I really have you."

Bai Zirui assembled the repaired radio and put it aside, while the other people squatted beside him happily listening to the radio, and he started to check and repair other broken radios.

Some of these radios were either broken resistors, capacitors or loose soldered wires. Fortunately, there were available electronic parts to replace them. He repaired five radios within two hours of busy work.

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

When the others got off work, they happily took the assigned radio home. Bai Zirui returned to the courtyard with his own radio with a calm face.

After seeing it, Yan Bugui immediately stepped forward and asked, "Zi Rui, 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. It's because some people are moving and it's not convenient to carry it. We can use the ones we collect at the recycling station.

Third Master, you can listen to it if you want!How about a monthly subscription for thirty cents? "

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

Bai Zirui said: "Third Master, I learned this from you. You can't eat poorly, you can suffer endlessly. If you can't figure it out, you will suffer poorly!"

The Yan Bugui that Bai Zirui said was speechless and walked in. Yan Bugui looked at his back and spat: "Bah! What's the air? Isn't it 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 yard talking about Bai Zirui bringing back the radio, so he came to the ancestral house and asked him, "Zi Rui, is this the radio that you fixed?"

Bai Zirui nodded and said, "That's right! Brother, if you like, you can take him to your room to listen."

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

Bai Zirui pursed his lips and said, "What's precious about a radio? It's very simple, and it's not as good as your phonograph, brother! Why don't we exchange it?"

He Yuzhu said without hesitation: "That's not acceptable! It's something given to me by the big leader. It's 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 person. Why do you have time to come here today?"

Wu Guohao took a sip of tea and said, "Zi Rui, the case of stick theft you reported a few days ago has been closed, and the court will make a formal verdict tomorrow. Am I here today to return your design drawings?"

Wu Guohao took out the design drawings while talking, put them on the table and pushed them to Bai Zirui, he put away the design drawings, and said politely: "It's just such a small matter, please trouble my brother-in-law to come to my place, please tell me Just let me know, and I’ll go to the police station to get it.”

Wu Guohao waved his hands and said, "This is all a matter of little effort. I'll come over and take a look. You just arrived in the capital from the Great Northern Wilderness. Is there anything else you need to help with?"
