Countercurrent 1982

Chapter 35 Small Defects

"I also saw it in the magazine article." Duan Yun said casually.

"But this kind of antenna is not very easy to use in our place?" Li Guosheng used his fingers to support the glasses on the bridge of his nose, and then said: "Our factory chief engineer Liu brought a Yagi antenna like this from the south, I'll go to him I've seen it at home, but I can only receive two stations, but the resolution of the provincial station is a little higher..."

"My antenna is not the same as the one in the south. I have redesigned the amplifier part." Duan Yun replied.

"Haha..." Li Guosheng smiled when he heard the words, but a look of disapproval flashed across his face.

At this time, the cloud has begun to re-check the antenna in his hand.

In Duan Yun's view, even if his antenna is not as easy to use as expected, it is absolutely impossible to be worse than the telescopic antenna on this TV before, and the current situation is that Li Yun's TV is even in the center. The signal is somewhat unclear.

When Duan Yun opened the tin case that wrapped the amplifier circuit board, he immediately understood the problem.

It turned out that the two solder points of the circuit board and the feeder were disconnected at this time. It is estimated that Duan Yun was a little careless when soldering, and the solder wrapped too little copper wire, and the wire head was repeatedly bent during transportation. In addition, the outlet of the white iron sheet There is friction, which eventually causes the copper wire joint to be broken.

This also gave Duan Yun a little experience, that is, a layer of protection must be added to the outlet of the wire and the casing to prevent wear and tear from causing disconnection or leakage.

Duan Yun took out the electric soldering iron and solder rosin that he carried with him, and began to re-solder the joint part.

After the welding was completed, Duan Yun carefully wrapped the joint part in two layers with insulating tape to prevent the copper wire from being rubbed off again.

After doing all this, Duan Yun finally breathed a sigh of relief and stood up.

"Xiao Duan, let's have dinner at my house tonight." Li Guosheng said to Duan Yun.

"No need..." Duan Yun shook his head with a smile.

"It's okay, Duan, you help my house install the wires, there is no reason for you to help me in vain. Besides, you and my parents are from the same factory, so what's the point of having a meal together." Li Yun said.

"Ah, that's fine." Duan Yun didn't make any more hypocritical words when he heard the words, and responded casually.

"Wife, warm up a few more steamed buns, and have a small dinner at our house in the evening." Li Guosheng shouted to the kitchen.

Picking up the antenna, Duan Yun walked to the window again.

"Try another station." Duan Yun instructed Li Yun after sticking his hand out of the window.

"Crack!"

As soon as Li Yun switched to the channel of the Central [-], the screen first flashed, and then a clear screen appeared.

"This...this is too clear..."

Seeing that the TV picture on the central one was much clearer than usual, Li Guosheng and Li Yun's father and daughter were taken aback. In fact, they didn't think that Duan Yun's homemade antenna would work.

However, what surprised them even more was still behind.

"Click." As Li Yun turned the knob again, two more pictures of cross talk in coats appeared on the TV screen.

"Jiang Kun, Li Wenhua!" Li Guosheng recognized the two of his favorite cross talk actors at a glance, looking a little excited.

"This is... Henan TV?" Li Yun, who was on the side with sharp eyes, immediately saw the station logo in the upper left corner, and then said excitedly, "This is the first time our family has received a program from Henan TV."

"Wife, cook another meat dish with more oil!"

Li Guosheng shouted to the kitchen again, and said to his daughter with an expectant expression, "Try another station!"

"Click!" With a light sound, the TV screen changed to the cartoon "Little Tadpoles Looking for Mother", and the station logo changed to Provincial Taiwan, Shanxi Station.

"Shanxi Tai has also become so clear!" Li Guosheng's expression became more and more pleasant.

"Change again..."

"Click!"

Li Yun kept turning the knob of changing channels, and after a few snowflakes, two more provincial channels appeared on the TV.

Now I can receive six TV stations, and two of them are barely able to watch although the resolution is not high.

Li Shengguo looked at Duan Yun again with a bit of surprise.

"Dad, "Volleyball Girl" is being played on this channel. I've wanted to watch this TV series for a long time." After Li Yun turned the knob back to the TV show channel, she never turned back.

"Go downstairs and buy a bottle of Lao Baifen for Dad!"

Li Shengguo said, took out a five-yuan bill from his pocket and handed it to his daughter.

"Dad, drink less alcohol, didn't the doctor say your blood pressure is a little high last time?" Li Yun didn't mean to reach out to take the money.

"Isn't this a guest at home? Xiao Duan has been busy for a long time, so drink some wine to relieve fatigue." Li Guosheng said solemnly.

"Don't come! You're just making excuses!" Li Yun saw through her father's thoughts at a glance, and didn't give her father any face at all.

"You can buy bubble gum and waffle cake with the rest of the money. Isn't this your favorite thing to eat?" Li Guosheng said with a smile.

"Wait!"

Li Yun smiled when she heard the words, took the banknotes from her father, turned and left the room.

"This girl..." Li Guosheng pouted and muttered to himself, then turned around and tuned the TV to Henan Channel, which played Jiang Kun's cross talk.

When Duan Yun saw that the resolution of the TV screen was almost the same, he directly used the hand drill and angle iron he brought with him to drill a hole by the window and installed a simple shelf, and fixed the antenna on it.

In fact, the way Duan Yun installed this antenna is wrong, but now the roof cannot be easily climbed up, and the line brought by Duan Yun is not long enough, so he can only temporarily install the antenna outside the window according to local conditions.

"Uncle Li, if the TV signal is not clear in the future, you can shake the antenna outside. If it still doesn't work, install the antenna on the roof. This is the first time I have installed the materials and tools at hand, so I can only install it first. It's outside the window, at least it's easy to adjust..." Duan Yun clapped the dust on his hands and said to Li Guosheng with a smile.

"That's good, the chief engineer's TV can only receive two channels, and your antenna can receive six channels. This technology is too powerful." Li Shengguo praised Duan Yun with a smile on his face.

Li Guosheng really admired Duan Yun a little bit. He never would have thought that there would be a master of this kind of electronic technology in the factory. .

"Xiao Duan, hurry up to the kitchen to wash your hands with soap and eat." Li Yun's mother greeted her with a smile on her face when she saw that the TV signal at home was much clearer.

"Hey." After Duan Yun responded, he packed up his tools and walked to the kitchen.

And at this time, Li Yun also bought wine and came back with a bubble gum in his mouth...
