We Live In Nanjing

  Chapter 43 There are a thousand old toads in a thousand 59+

  After ten o'clock in the evening, Bai Yangtong got on BG4MSR.

  Three greasy old men squeezed over to listen to the corner of the wall, winking at the same time, showing the expression of "you can do it, kid".

  Bai Yang was very annoyed, and kicked the three old people out.

"This is Xiao Yang's signal, it's weird... why is it so weak." Wang Ning pointed to the wave crest on the spectrum analyzer display and looked up at the ceiling. "We are under the antenna, right? Old Bai, you use it now. What antenna?"

   "DP antenna." Bai Zhen said, "the same one as before."

Wang Ning was amazed, "As expected of Lao Bai, I admire you for this. You can set up such a large antenna in the community, and no one has been complained? The old man and the old lady didn't come to your door and say that you have radiation that can cause cancer? "

   "Yes, they are looking for the property, and the property is looking for me." Bai Zhen said.

"how do you say?"

  "I said that I have complete licenses and licenses, which are legally erected. If you have the ability, you can go to Wuwei to find Wang Ning. His address is No. 37, Longpan Middle Road, Xuanwu District. Enter the door to find the one with the least hairy hair."

   "Fuck." Wang Ning said.

The wave crest on the spectrum analyzer display rises and falls. When it rises, it means that the poplar is talking, and when it falls, it means that the poplar is listening. Icom725 is a half-duplex working mode. This thing cannot be transmitted and received at the same time. From the perspective of a layman, its experience Similar to a walkie-talkie instead of a cell phone, Bai Yang presses the send button on the mobile microphone, and he can't hear what the other party is saying. Only when he releases the send button on the mobile microphone can he receive the signal from the other party.

  This is why the radio communication usually adds an “OVER” or “complete” at the end of the sentence, just to let the other person know that he has finished speaking and the other person can speak.

  Wang Ning’s idea is very simple. They listened to the voice of the poplar in the room while staring at the waveform graph on the display of the spectrum analyzer.

"...Yes, we are doing experiments. Do you know that the spectrum analyzer? It is an instrument that can receive and analyze radio waves. It is now in my living room." Bai Yang's voice came out of the room, "They are three in there. Check the signal, I hope to find the reason for all of this, but it is still preliminary work, OVER."

  Following Poplar’s ​​voice, the peaks of the spectrum analyzer display fluctuate. The bandwidth occupied by the SSB mode is very narrow, so it is a steep and narrow peak like a mortar ballistic.

  Bai Zhen, Wang Ning and Zhao Bowen all heard Bai Yang’s "OVER".

  Okay, now Bai Yang is finished, the next step is BG4MSR. If the spectrum analyzer can receive the girl’s signal, a peak will be raised at the frequency of 14 MHz...

  All three of them opened their eyes wide.

  "Where is the crest?" Zhao Bowen asked.

  There are only jagged back noise lines on the spectrum analyzer display.

  There is no wave crest.

   "Xiao Yang——!" Wang Ning shouted, "Is she talking?"

  Waiting in the room for a few seconds, Bai Yang replied: "Yes!"

  "Why is there no signal while talking? This is really the hell." Bai Zhen murmured, even with his experienced HAM, he has never encountered such a situation.

   "Xiao Yang! Report the RS signal report!" Wang Ning shouted again.

   "59+!" Bai Yang replied.

   "Impossible, the spectrum analyzer can't even receive the 59+ signal?" Zhao Bowen frowned.

   "Don't worry, I'll try it myself." Wang Ning got up and entered Bai Yang's room, "Xiao Yang--! Let me have a look!"

  As the saying goes, one thousand old toads have one thousand 59+. An unscrupulous toad like Lao Bai catches a signal and gets 59+. It is hard to guarantee that Xiao Bai did not inherit his father's habit.

  Wang Ning came back a few minutes later, and Zhao Bowen and Bai Zhen saw a face that shocked the ancient Shuojin under his shiny forehead.

  What kind of shock is needed to make Wang Ning’s old face shock the past and the present.

  "Close your mouth, the split is bald." Bai Zhen said, "What's the situation?"

   "Old Zhao, if you win the Nobel Prize in Physics, can you give me a name?" Wang Ning asked.

   "Okay, no problem, I will definitely burn you until the day I get the Nobel Prize." Zhao Bowen nodded, "Let's talk, what's the situation?"

   "The signal of 59+ is completely clear and identifiable, no problem." Wang Ning sat down in the chair, "I can't explain, Lao Bai, you didn't do anything about it? Encrypted the signal?"

   "I don't have that ability." Bai Zhen said, "I don't have that ability when turning two or five."

  There was weird silence in the living room. My mother came out of the room and saw three men sitting on the sofa and chairs silently. She couldn't help but feel a little curious:

"what happened?"

   "The story made by Yang Yang is not true, right?" Zhao Bowen asked in a low voice, "Is there really a signal to travel through time and space? BG4MSR will really live in twenty years?"

  "Are you a professor, you came to ask us?" Bai Zhen said, "Are the ten years you have read more than us for nothing?"

   "Deputy." Zhao Bowen said.

  "Don't rush to conclusions, we will think of a way."

  Wang Ning took out his mobile phone from his pocket and began to dial:

"Hey——! Xiao Zhu, hey, yes, it's me, where are you now? Have you gone home... Ah that's just right! That's right! Xiao Zhu, do you want to do me a favor? Are you free? Just go back to the office and help me get another spectrum analyzer, the HP one, yes, yes, white... I'm really sorry, I'm going to trouble you again, I will invite you to dinner tomorrow."

  After half an hour.

  The breathless young man appeared at the door again, holding a white HP old-fashioned spectrum analyzer in his arms.

  Lao Wang once again said that he would stay for a drink.

  Xiao Zhu waved his hand to say no, and disappeared in a slip of smoke.

  "Which leader are you? The young man worked hard to help you run errands at night, and you asked him to drink?" Bai Zhen was angrily.

   "Whose saliva to drink?" Zhao Bowen asked.

   "You two can force me to die, right?" Wang Ning put the second spectrum analyzer on the table and plugged in the power supply, "Come on, take a look at this one!"

  The first spectrum analyzer cannot receive the BG4MSR signal, which may be a problem with the spectrum analyzer.

   Then try another spectrum analyzer.

The three men stared at the spectrum analyzer display, and the old HP's oscilloscope gave off a terrible green light. The age of this thing may not be as old as the three old things present, but it is old and old, the golden gun will not fall-Wang Ning's The original saying is "It is as strong as I am, and has worked for the health of the motherland for fifty years."

But the veteran who had always stood firm and stubbornly stubbornly fell into the sand this time. The second spectrum analyzer could still only capture the white poplar and could not display the BG4MSR signal. In the end, Wang Ning even moved the spectrum analyzer to the white poplar room altogether. The Icom725 radio station is only one meter apart, and both parties started working simultaneously-for this purpose. The BG4MSR signal still ignores the spectrum analyzer, and only the broken radio station Baiyang can receive it.

  This is incredible.

   "I knew it." Bai Zhen slapped his thigh, "Old Wang said that the state of this thing is the same as himself, wouldn't it be over? It's all Alzheimer's."

  The three people present, Bai Zhen, Wang Ning, and Zhao Bowen are all experienced amateur radio experts, but no one can explain this phenomenon.

  Why is the signal of BG4MSR selectively received by Baiyang’s Icom725?

  Is this radio wave refined?
