Chapter 1215

Electromagnetic waves, radio, yes radio!Li Sansi suddenly thought of a way to contact Dalin Temple. The emission wavelength and distance of electromagnetic waves are very far, but if you want to transmit a large amount of complicated content, such as a paragraph or a song, it is difficult to complete without corresponding complicated equipment, and Even if it is made with electronic components that can be bought in the market, the general transmission distance, up to 100 meters, is already very remarkable.Generally speaking, it is very simple and easy to simply use the radio Morse code to communicate without transmitting a large amount of complex electromagnetic wave information. If there is a monitoring station of Dalin Temple near Nanzhou City, then only need to use electromagnetic waves Entering the Morse code will definitely be perceived by Dalin Temple, and such a simple and easy launch tool is a piece of cake for Li Sansi, a doctor of physics.

Thinking of this, Li Sansi almost didn't give his head a blow. Such a simple and easy method, but he didn't expect that the world's oldest electromagnetic wave communication technology is called ContinuousWave, or CW for short, that is, constant-amplitude radio telegraph. , This kind of telegraph has extremely strong anti-interference ability, and only needs a small amount of power to reach a distance of thousands of kilometers. Often, a CW with a power of 2w may be able to get in touch with America in Haishan City.

Thinking of this, Li Sansi acted immediately, looking for the radio in the Anjia villa. The components required for this electromagnetic wave technology communication technology are equipped with ordinary radios. With Li Sansi's means, he only needs to dismantle them one by one. Come down, and then reassemble it again. Li Sansi searched the room, but unfortunately he did not find any electrical appliances such as radios. Then he opened the room, rushed to Ankang's house, knocked on the door, and Ankang nodded. He opened the door with an earphone on, blinked his eyes, seemed to be listening to some heavy metal song, shook his head and looked at Li Sansi in front of him in confusion.

Li Sansi took off his earphones and asked, "Is there anything like a radio? Lend me to dismantle it. Use it?"

Ankang was stunned for a moment, as if he didn't realize what Li San wanted to do with the radio, "Say, what exactly do you want to borrow?"

"Radio, do you have one that listens to Guangbo? I need it urgently!"

"Well, I don't have a radio, but my mobile phone has a radio function, but, what do you use the radio for?"

"Mobile phone?" Li Sansi was stunned, and asked suspiciously, "Is there not a bigger, dedicated radio?"

Ankang scratched his head, thought carefully, and then murmured, "It seems that there is, but it belongs to my sister. That special radio, she seems to use it every night to listen to the night performances from Vienna."

"Thank you!" Before Ankang finished speaking, Li Sansi disappeared in front of him.

Just when Ankang was about to close the door, Li Sansi reappeared in front of him. The elusive movement really surprised Ankang. Li Sansi stretched out a hand, "Lend me the phone."

Ankang took out his mobile phone suspiciously and handed it to him. Seeing that Li Sansi was about to disappear again, he quickly said, "Wait, there are still earphones!" Then he took out the earphones and handed them to Li Sansi , Seeing the shadow of Li Sansi leaving in a hurry, Ankang closed the door suspiciously, and sat back on the bed again. I don’t know why Li Sansi is so anxious to ask for the radio. Maybe he wants to listen to the ghost stories every night, or the radio station? song or something?With Li Sansi's lazy and indifferent character, there are radio programs that attract him, which makes Ankang a little surprised. He shook his head, put on the wireless earmuffs again, and the heavy metal music came overwhelmingly.

"Here we come." An Yuan opened the door, wearing a down jacket, covering her body in pink pajamas, blinking her eyes under the long eyelashes, pinching the sides of the down jacket to cover herself pajamas, looked at Li Sansi in front of him in confusion, "Aren't you sleeping yet?"

"Well, I want to borrow something." Li Sansi looked over An Yuan's body and looked into the room. An Yuan's room was well-organized, especially the bed was surprisingly big. A pink curtain hung down from the roof. It covers the entire bed, making people want to lie on it at a glance. On the crystal clear glass table, there is something like a small rice cooker. It has a streamlined egg-like shell, and a pair of black earphones extend out from the top of the machine. The shining antenna made Li Sansi feel excited for a while. This is his dream radio, and it looks quite high-end. Li Sansi seems to have found countless hopes. After this, those things, All thrown away.

An Yuan was just thinking about the things she wanted Wang Nan to say to Li Sansi at the banquet today. She didn't think it was a big deal when she said it. Now that she thinks about it carefully, she acted like a baby to Li Sansi. The way she looked, those words she said to him, recalling them, made her heart beat fast, her cheeks were red and hot, and she almost felt ashamed, but now when she heard the knock on the door, it was Li Sansi standing beside her. In front of her, she almost made a hole to go to the next floor.

And Li Sansi stood in front of her, looking into her boudoir with interest, and her face, which had been calmed down a little, suddenly became flushed again, and she lost her usual vigor, but she was a little whispering said, "What do you want to borrow?"

Li Sansi chuckled, scratched the back of his head, and said embarrassedly, "Well, I want to borrow the radio. Do you have it? If so, can you lend it to me?" Li Sansi knew this The eldest lady was moody, so her words became more tactful and more cautious. Her radio kept his hope of contacting Dalin Temple. How could Li Sansi not be humble.

An Yuan was startled. Listening to the Sound of Music in Vienna every night has become an indispensable habit for her. Only her radio in the whole house can receive the radio waves from Vienna. But now the beating in her heart has already She couldn't think of anything more. When Li Sansi stood in front of her, her heartbeat suddenly accelerated and her breathing became short of breath. She didn't know what was wrong with her, but the only thing she knew was that she wished Li Sansi would disappear quickly. in front of myself.

An Yuan was holding her own radio with a blushing face, the red face was the same color as the red radio, beautiful and cute, she didn't speak, put the radio in Li Sansi's hand, pouted and said, "Okay, here you are gone."

Li Sansi walked out of An Yuan's room in a daze. Originally, he had heard from Ankang that An Yuan would use it to listen to music every day. He was still a little worried. Now she gave the radio to him so readily and closed the door. Li Sansi's impression of her changed again. People say that women's minds are like a sea, unpredictable, and they speak bad words to themselves in the morning, but in the evening, the situation changed, which made Li Sansi feel cold and turned off the radio. , like a thief, quickly slipped back to his room.
