"Go, I'm at home after work at night, and people wish you could go early. Duan Fang replied casually.

"Then it's decided!" Duan Yun said, taking out the address slip that his sister gave him yesterday from under his pillow.

......

At five o'clock in the afternoon, Duan Yun got up and left his rental house after modifying the more than 20 radios that his sister gave him at noon.

After locking the door, Duan Yun strode towards the three living quarters of the factory.

According to the address given to him by his sister Duan Fang, Duan Yun came to the door of a household on the second floor of Building 15.

The factory morning shift is four o'clock in the afternoon, which is the time when many people cook and have dinner.

Duan Yun knocked lightly on the door.

"Who?" came a woman's voice inside.

"Auntie, I'm Duan Fang's brother Duan Yun, do you have a radio to repair at home?" Duan Yun asked politely.

"Squeak. ”

As soon as Duan Yun's words fell, the door was opened from the inside, and a middle-aged woman with a somewhat fat figure appeared in front of Duan Yun.

"Ah, you're Duan Fang's brother, come in. After looking Duan Yun up and down, he motioned for him to come in.

This is a juxtaposition of about 20 square meters, although it sounds not much larger than Duan Yun's house, but it has an independent kitchen and bathroom, which is obviously a lot more convenient than Duan Yun's tube building.

In fact, the three living areas of the gear factory are the latest and best areas of the whole factory, and the houses were newly built three or four years ago.

On the other hand, these people are also the highest wage earners in the factory.

Glancing around the middle-aged woman's house, the electric fan, vertical radio, and sewing machine in the room were all wiped clean, and on the old-fashioned suitcase opposite the bed, there was a 12-inch black and white TV.

Just looking at the furniture arrangement, it is a proper well-off in this year.

"Xiao Duan, eat the apple!"

At this moment, the middle-aged woman walked in with a plate of washed apples and placed it on the folding table next to the aisle.

"Thank you, Auntie!" Duan Yun smiled when he heard this, but didn't move the plate of apples, but walked to the half-meter-tall old-fashioned radio placed next to the wall, and asked after a while, "Auntie, is there anything wrong with your radio?"

"It's been more than half a year, the noise is very loud, and many stations can't be collected. The middle-aged woman came over and slapped the radio and said, "I've wanted to change it for a long time, but I'm a little reluctant to throw ......it away."

"Actually, it's a good thing, the new radio doesn't have such a good speaker. Duan Yun squatted down to check the chassis, looked up and said to the middle-aged woman, "Auntie, can I open it and take a look?"

"Whatever. ”

"Do you have a dry rag?"

"I'll get it for you. The middle-aged woman said, turning and walking out of the room.

Taking out the tools he had brought from his body, Duan Yun quickly opened the back cover of this radio.

This was Duan Yun's first on-site repair, but the process was surprisingly simple.

This is definitely an old-fashioned four-tube semiconductor radio, and the lid of the box is also printed with the words '*** long life without borders'.

It was definitely not ordinary people who could afford this kind of vertical radio back then, and now it is completely reduced to chicken ribs.

The components inside the chassis have been out of production for many years, and it is simply impossible to buy them on the market.

The thumb-thick diode and fist-sized capacitor will definitely be a treasure for electronics enthusiasts in later generations.

However, despite this, due to the simple mechanism of the machine, Duan Yun can be completely replaced with the new electronic components on hand.

Taking the rag from the woman's hand, Duan Yun gently wiped the electronic components inside, then opened the multimeter and tested the components inside one by one.

Soon, Duan Yun found out that one of the transistors had turned black, and the resistance value was amazing.

Plugging in the soldering iron he was carrying, Duan Yun took out a diode from his pocket and replaced the original component.

In order to ensure the sound quality of the radio, Duan Yun made minor modifications with some parts.

After doing all this, Duan Yun turned on the switch on the radio, and after simply debugging the channel, it immediately came out of the Central People's Radio broadcast "Please Come to the End of the World" sung by Shen Xiaocen.

"Please come to the ends of the earth, where spring is always present in all seasons

The spring breeze on Hainan Island is warm, and the good flowers make you happy

March is coming, the flowers are red, May is coming, the flowers are blooming......"

A clear voice echoed throughout the room.

"Xiao Duan, your skills are okay. The hostess, who was washing vegetables in the kitchen, immediately returned to the room with a smile after hearing the song, and asked Duan Yun after a while, "How much?"

"Thirty ......"

"Forehead ......" The middle-aged woman's face suddenly became a little ugly when she heard this.

"I'll help others provide door-to-door service for at least thirty, but it's good that Auntie, your daughter and my sister are classmates......" Duan Yun pondered for a while, and said after a while: "In this way, I'll just charge a cost price of fifteen yuan, and I also replaced several capacitor diodes just now......"

In fact, the cost of Duan Yun's components was less than a piece, he deliberately offered a high price first, and then gave a 'cost price', which made this middle-aged woman feel very profitable, after all, Chinese people like to bargain, and Duan Yun also knew this.

"Then thank you, I'll give you the money!" Sure enough, hearing Duan Yun say this, the middle-aged woman suddenly smiled like a flower on her face, opened the lid of the suitcase next to her, and took out the money from it.

"No thanks, Auntie, just help me promote it in the future. At this time, Yun's gaze had shifted to the 12-inch black-and-white TV, and then asked, "Auntie, how much money did you pay for this black-and-white TV?"

"The peony brand was bought by my family on a business trip to Beijing last year. When the middle-aged woman heard this, a touch of pride flashed on her face, and she said, "It cost a little five hundred yuan......

"Well, at first glance, it's a high-end product. Duan Yun looked 'envious' when he heard this, and after taking the money from the middle-aged woman, he asked, "How many units can you collect?"

"Central One and Shanxi TV. ”

"Just two?" Duan Yun was a little surprised when he heard this.

This was somewhat unexpected by Duan Yun.

In fact, in the early 80s, many domestic TV users could only receive the central one, and generally there was no one during the day and only at night.

"News Network" at seven o'clock, "Alarm Bell" at eight o'clock, then "Movie", then "At Your Service".

If the TV signal is good enough, you can also receive two or three provincial stations.

Duan Yun carefully observed this black-and-white TV, and when he found that this black-and-white TV still used its own lever antenna, his mind suddenly moved, and then he said to the middle-aged woman: "Auntie, can I discuss something with you?"

"What's the matter?"

"I want to help you make a special antenna, which can receive a lot of ......" Seeing the middle-aged woman's embarrassed face, Duan Yun immediately added:

"Don't worry, I'm free this time, and you don't have to pay a penny!"
