I Wore It Back After 60 Years

Chapter 908 Telegraph Machine

For several days in a row, Li Xingxing was studying and making up lessons in his room, and he was dizzy from studying.

Why can't she be a scumbag?

Just eat, drink and have fun, no need to chisel the wall to excuse the light, no need to hang the beam on the head to bite the bone.

She is good at foreign languages, but she is weak in science, and she is good at mathematics. She has a foundation taught by her grandfather, and she is the worst in physics. As for the subject, Xia Mingxing answered it quickly and well. After listening to it, she didn't even think she could.

She has a wealth of knowledge, is at her fingertips, and teaches better than the school teacher, so she keeps digging into her head.

He also assembled a telegraph using some parts they bought when purchasing materials.

"Is it a telegraph that uses Morse code? I used to watch TV with my grandfather, watch anti-Japanese war movies and spy movies, and the small telegraph inside often sent intelligence information thousands of miles away, which is amazing." Li Xingxing thought It's very novel, just press the buttons on it randomly, "How far can the radio waves transmit the telegraph you assembled?"

Xia Xingxing smiled, "It's no problem to transmit thousands of kilometers."

Li Xingxing admired it very much.

Xia Mingxing rubbed her head, "It is related to the power. The greater the power of the station, the farther the message will travel. A long time ago, I used long-wave and medium-wave at the beginning. Later, when I encountered difficulties, I discovered that short-wave can be used. Reflections from the ionosphere in the atmosphere can spread thousands of miles away, and large radio stations can achieve global communication."

Li Xingxing was confused, "What is the ionosphere?"

"After the atmosphere is irradiated by sunlight, a layer of charged air is formed, called the ionosphere, which is about [-] to [-] kilometers above the ground." Xia Xingxing told her patiently, "When radio waves enter the ionosphere... ..."

Li Xingxing quickly stopped: "Stop! I'm not a telegraph operator, don't explain to me."

She was afraid that Xia Mingxing would continue, so she quickly changed the subject: "When we are about to arrive in Shanghai, send a telegram to Dad on the sea, asking him and Mom to come to the pier to meet grandparents!"

Xia Mingxing was planning to do so.

Whether it is the tens of millions of foreign exchange they brought back to China or the two sets of [-]% new industrial equipment are very important, Chen Xiangyang must be informed to make arrangements early and prepare a residence for the two elders in advance.

Before their departure, due to the uncertain return date, they did not notify the relevant domestic responsible persons, and they may encounter trouble when entering the country.

"I'll teach you how to send a telegram when the time comes." Xia Mingxing teased the little daughter-in-law.

Li Xingxing shook his head frantically, "I don't want it, I don't want it, as long as you know how to send a telegram!"

Memorizing Morse code is a waste of brain cells!
"As smart as you, is it so difficult to study?" Xia Mingxing flicked her head with her fingers, and the movement was very light. "If you don't study hard, how will you be admitted to graduate school? How will you get a high degree?"

Li Xingxing said casually: "College students are enough. I wanted to be a graduate student because I didn't want to be a teacher."

Being a soul engineer is not so easy, and you need to face various risks in the future.

Xia Mingxing looked helpless, but he didn't continue.

He felt that Li Xingxing didn't want to study because she played crazy during the time abroad, and when she returned to China, she didn't have entertainment and shopping, and she should be able to calm down when she was doing nothing.

After more than ten seconds of silence, he said, "Take out the ammunition, and I'll tidy it up and put it in an empty suitcase."

When organizing jewelry, leave some empty suitcases for secondary use.

Li Xingxing snorted, "Brother Xia, are you going to take the ammunition across the Ming Road? Pack it in my suitcase, which can fool grandparents and them, and hand it in conveniently when entering the country."

Xia Xingxing nodded, "This batch of munitions is of great research value and must be handed over."

Li Xingxing smiled, "I understand, I understand."

It's a big copycat country!
