Chapter 2: Gray Building No. 9

Waking up from the chaotic thoughts, Tan Zhenhua felt that two of his own memories were gradually merging. It seemed that the incredible thing was true after all. After he came, he was safe. He was a man for two lives. He quickly adjusted his status and repositioned himself as a senior high school student in the early 1980s.
It was already bright. He looked at the alarm clock on the table. It was 6:30. Knowing that he flew up to the top of the sycamore tree outside the window, he began to "squeak". Tan Zhenhua took a deep breath, the morning dew mixed in the air. The fragrance of the earth and the earth filled his nose.
"Well, the smell of air without haze is so good," he thought.
I found the toothbrush, washbasin, and towel in the corner of the house, went out, and walked through the long corridor. On both sides of the corridor, there are households. At the end of the corridor, there are public water rooms, toilets and kitchens. Yes, the kitchen is also shared. Each house has a small area, just enough to put a small coal stove and stove. This small building has a total of two floors. Tan Zhenhua lives in the third room facing north. His father Tan Ming and mother Xu Yun live in the opposite room. There are 6 households on this floor, all of whom are employees. Tan Zhenhua While walking, greet the neighbors and elders around:
"Aunt Yang early"
"Well, Xiao Hua is also early, school starts today?"
"Yes, yes, did Xue Zi get up?"
"Hey, Xue Zi is not as diligent as you, he is still lying in bed!"
"Oh, tell him later, I'll wait for him to go to school together"
"Well, okay, okay, Xiaohua, you have good grades. This year, you can help our family Xue Zi. It's a third year in high school. It's too late if you don't hurry up."
"You must be sure, Auntie, don't worry, Xue Zi is my best friend. We are still a bunch of one in the class, one pair of red!"
"Yes, yes, I'll pick up Xue Zi. If this stinky boy is half as good as Xiaohua, I will be relieved."
Fleeing the babbling Aunt Yang, Tan Zhenhua trot into the water room. As soon as he looked up, he saw a tall and strong guy taking a sip of water with his big head gargle in that grunting mouth. Tan Zhenhua played with his heart. He paused, walked around behind this guy, slapped his shoulder, and shouted:
"Little Treasure!"
The big guy was so violent, he couldn't hold back for a while, and he swallowed all his mouthwash with a "grumbling", and because he swallowed too fast, he was coughing desperately there.
The big man turned his head angrily and saw Tan Zhenhua. He immediately raised his big fist of the sand bowl and prepared to smash his hands. He saw Tan Zhenhua calmly and waved his hand:
"If you do it, you won't have to copy homework."
The big man fainted immediately, and said frustratedly: "Tan Zhenhua, count you cruel!" Turning his face, he showed a traitorous face and said, "Ah, what good is just copying homework? During the exam, the papers Put it down too, that's the real brother!"
Tan Zhenhua "hehe" happily, and said: "No way, of course you have to take the exam yourself, how can you cheat? That's against school discipline and my bottom line!" He lost another "you know" look at him. That big man, the bottom line for him to be a man is by no means as high as he threatened. When the big man saw it, he immediately understood, touched the back of his head, and went happily.
After washing, I hurried to the public kitchen next door and saw the middle-aged woman who walked in last night—that is, both his previous life and this life were his mother-in-law, Empress Xu Yunxu.
After a night of memory fusion, the little bit of a sense of disobedience facing relatives in different time and space has long been diminished. Seeing Queen Mother Xu busy in front of the stove, she leaned up without skin and face, Xu Yun waved her hands like Drive him out like a fly: "Go, go back to the room and stay. Breakfast will be fine for a while. Also, you are not allowed to bully Xiaobao anymore. You see how strong the parents are. If you want to shoot, you must follow the shoot. Like a little chicken, they have been letting you!"
Tan Zhenhua rolled his eyes and wandered out of the public kitchen, went back to his room, put down the washbasin, towels, and dental appliances, picked up his schoolbag, and walked in the opposite door.
His father, Tan Ming, still looks like he remembers. He is not tall, about 1.7 meters tall. His face is yellowish, thin, and he wears a pair of black-framed glasses. I don’t know if it’s because of genetics or overuse of the brain. Great, but in this era, thin is the normal body shape, right?
Dad is an expert in radar display. The display part of China’s first domestic monopulse Doppler radar in 1964 came from his handwriting. According to his self-proclaimed experience, the circuit boards in there were all soldered out one by one with a soldering iron.
However, it seems that it is a little early to be called "Dad". This was in 1981, and Tan Ming had just reached middle age.
The early father was playing with his new toy-a black-and-white TV set by himself. Tan Zhenhua knows that his father has a very strong hands-on ability. The radio and phonograph at home are all assembled by buying parts, but they are all placed in the room of his parents. There is no room in his own room. , After all, his main task now is to read books.
Being able to DIY everything is also a feature of his generation, who can install it by himself and never buy ready-made ones.
One thing is to save money. After all, it’s cheap to buy parts. Some parts can still be bought from public accessories. Bulk resistors, capacitors, tubes, transistors, etc., bought in batches from public houses, are selected for military products. (You are absolutely right. In the early 1980s, Rabbit Electronic tubes can be seen in many equipment at home. This gadget was even used until the end of the century. It was mainly power components. At that time, the rabbit’s industrial foundation, especially the semiconductor technology, was too thin, and many high-power devices were made of transistors. If it doesn’t come out, the integrated circuit is even more shadowless. There is no way, you can only use the tube. This is completely different from those tube amplifiers played by enthusiasts.) Those parts that fail to meet the requirements are in the laboratory. Some will be left for equipment experimentation. The rest, as long as they are not restricted materials, can be dealt with at a cost if employees want it.
Secondly, my dad is really awesome, so I looked at the schematic diagram in the "Radio" magazine and figured out the actual drawing of the TV. You know, in order to save money for the parts of this TV, my dad quit smoking for more than 20 years. A few days ago, he finally got enough parts and started to assemble—if I remember correctly, the copper behind the picture tube The wire deflection coil, or I helped Dad wind it during summer vacation.
"Dad, can this TV turn on?" Tan Zhenhua asked.
"Well, I installed it last night. I tried it and it turned on. There was a problem with the signal reception. I guess there is a sliding resistor on the VHF receiver. The resistance is wrong. I need to adjust it again." Tan Ming said so.
"By the way, Dad, does your unit have any high-power high-frequency transistors that can be handled? The 3DA starts?"
"That's restricted supplies, what do you want that?"
"Don't worry, I don't work as a spy radio station. I just want to be a beacon for radio fox hunting. A power of 2W is enough, and 1W is OK."
"No way, you are in the third year of high school this year, so you still want to deal with the college entrance examination, don't even think about it!"
The so-called "radio fox hunting" is an activity of directional finding a target. First install a radio source called a beacon in a secret place, and then let everyone use the receiver, or the directional tester, to find it, and the competition will see who finds it first. This is a sport that uses the directivity of radio transmission, and it was very popular among radio enthusiasts in the 1980s.
Tan Zhenhua has a family background. He has participated in this sport since he was high, and even served as the captain of the school team. The receiver and receiving antenna were all made by him. Of course, he also got the help of his father. First prize in the youth category.
He wants to be a beacon by himself, so the minimum transmission power must be 1W. "3DA" at the beginning, it means that the high frequency triode of silicon material, the working frequency is greater than 3MHZ, the minimum power is also above 1W. However, this thing is a controlled material, because it can be used as a shortwave radio station. It is not available in the market and is basically not allowed to be used by private individuals. If you want to make a radio station, the National Security and the Radio Administration Bureau will do it every minute. Can come to your house to check the water meter, there were still many Taiwanese secret agents lurking in the mainland at that time.
This thing is only available in the institute, and it must be filed with the Radio Administration Bureau when it is done. Tan Zhenhua had long wanted to make a beacon machine by himself, and he could find someone to hide it, and then he could play with himself. Unfortunately, his father was ruthlessly stifled...
Rolled his eyes helplessly, just as his mother came in with breakfast, Tan Zhenhua took a look at it, steamed buns, porridge, a dish of side dishes, um, and a boiled egg. It was very obvious that the boiled egg was his third year welfare. He remembered, His brother Zhenguo also ate boiled eggs in white water for a year when he was in the third year of high school. When the old brother was really tired of eating, he also followed it for a lot of times. Now it is his turn finally. In this era, A meal of one egg a day is quite a luxury.
Sitting at the small dining table, Tan Zhenhua ate while listening to her mother's nagging—well, no, mom is now in her early 40s. Although she has some white hair and crow's feet, she must not be considered old!
The nagging content is the same as before, such as "study hard, learn hard, and learn hard" or something. Tan Zhenhua couldn't help but think of his previous life. Her 80-year-old mother would nag at him every time she met, but the content had become "Pay attention to the body, pay attention to the body, and pay attention to the body... …"
Just why, my eye sockets are a little moist?
After hurriedly eating breakfast, picking up his schoolbag, and bidding farewell to his parents, Tan Zhenhua went out, walked down the stairs, and looked back. What you see is a row of neat gray brick buildings, each of which is two low , The only difference, I'm afraid, is that the west wall of these small buildings, which is painted in white and gray, is numbered from "1" to "9".
This is the legendary Grey Building No. 9!
In the memory of his previous life, this quietly standing in a corner of the group house, with a slight vicissitudes in the gloom, the two-story, inconspicuous gray building No. 9 was born only in the older generation. Academician, four "Chief Teacher" level researcher-level engineers who enjoy special national allowances. Of course, his father is also one of them. There are more than 8 senior engineers who have served as system designers. There is another alternative, only junior high school. Culture, but is known as the "Treasure of the Town" 8-level fitter! Their names are firmly engraved on the monument of the Republic's achievements, and they shine with the sun and the moon!
This small building is so legendary that after decades, when the institute demolished the old building in the institute to transform it into a modern R&D office area, the building that had become a "dangerous building" at the time was still It was approved by the staff representative assembly of the institute and was retained. After reinforcement and reconstruction, the appearance of the building was preserved to the greatest extent. Only after the interior renovation, it became the "Exhibition Hall of the History" and received a glorious name "Huiying Building"!
And this "Huiying Building" has a fixed task, that is, when new employees are recruited every year, they are the first lesson in education!
Standing in front of this legendary small building again, looking at the familiar and unfamiliar gray brick wall, Tan Shenghua couldn't help but become fascinated.
