Chapter 44: Seek cooperation

Toss half a night, the bamboo basket fetched water.
Eight people were listless, but they didn't even want to sleep. They didn't even go to the black floor. They just sat around on the ground, pulling their heads in a daze, or in a daze, or melancholy.
The atmosphere of the whole kitchen was dragged into the endless black hole by these eight frosted eggplants.
"Someone upstairs seems to be beating us ..." Qiao Siqi reminded his friends weakly.
"If you really want to jump down, let him beat him, and I am also depressed." Zhou Lu sighed, and wiped the blood on the blade silently with a dirty rag that was found somewhere.
"Actually, I'm not afraid if there is no signal, there is a problem with the mobile phone and the network, and the TV is normal. I'm afraid ..." Luo Geng stopped talking and continued for a long time. "I'm afraid that the signal source will not be destroyed. But there is no news at all. "
"Impossible," Song Fei denied it without thinking. If he was hesitant before that, he is now decisive. "We can kill a few zombies with fish, shrimp and crabs. The state can't control the situation? It is difficult to smooth out 9.6 million square kilometers. It is absolutely no problem to concentrate troops to stabilize the heart area first. "
"Then I can't figure it out," Joskey crossed her legs, adjusted her sitting posture, her brow furrowed, and her tone of voice was quite agitated. "This TV signal is not like a mobile phone signal. It ’s enough to build a base station nearby. Is n’t a TV tower enough? As soon as the signal biubiubiu is launched, the TV can be received as soon as it is received. Is the TV tower also pushed down?

Song Fei language stopper. I always think that Joskey's statement is weird, but as a layman, he can't say a ugly man. Obviously it is the most common thing in life, but it seems that I never thought about the technical principles of the past.
Subconsciously look at Qi Yan-to find Qi Yan when you don't know anything, it has become a deep-rooted understanding of Song Fei.
Qi originally wanted to listen to the crowd with his eyes down as a professional, but when Song Fei ’s voice suddenly fell silent, he knew that he should always come.
Hesitantly raised his upper eyelids, as expected, a pair of eyes longing for truth.
Former Qi Yan enjoyed being gazed like this, because he was always able to answer questions and even talk about things. The questions that Song Fei can mention are nothing more than study, life, life, ideals, green days, no one will talk about love and suddenly ask, hey, do you know how TV works?
"Cough," Qi Yan cleared his throat, and half-guessed half-analyzed, "The signal sent by the TV tower is similar to the wireless signal, the kind received by the antenna? But now it is all cable TV set-top boxes, I think it should not be biubiubiu It's that simple. "
Song Fei thought deeply, and felt that Qi Yan was right.
Although the words were answered to Song Fei, it was obviously refuted that Qiao Siqi, who was not happy: "Do you mean that the TV tower is useless now? Pure sightseeing?"
Song Fei didn't figure it out at all. After being in the area of ​​Qiao Siqi, he felt that Qiao Siqi's question was also right, and then looked at Qi Yan again.
Qi classmates can't edit any more, helplessly spread their hands, and frankly told: "I'm just a student."
Song Fei froze for a while, and then the black line: "Then you just say don't know it!"
Qi Yan bowed his head in dismay, speechless.
This time is different from the past. He is still him, but Song Fei is no longer that Song Fei, and the world is no longer that world-the pressure that once pretended, slowly return it.
"Who said the TV tower is pure sightseeing," Lin Dilei, who had been listening, finally found a place where she could plug her mouth. To be honest, although I learned to broadcast and host, what is involved in the transmission of TV signals is actually in the field of communication engineering. She also knows a little bit about it, but when it comes to the role of the TV tower, she always knows the approximate, "The reason why the TV tower is so repaired High is because it needs to receive and transmit signals. In the early days, when there was no set-top box, old TV sets all had antennas, just to accept the analog signals transmitted by the TV tower. "
Qiao Siqi still puzzled: "You also said, it is early, now every household cable TV, who still uses the antenna, is that signal useless?"
Lin Dilei took a breath and explained patiently: "There is always a place where there is no cable TV, like in remote mountainous areas, so at this stage, a certain number of analog signals must be maintained. And the TV tower does not only emit TV signals. If you are I have watched it carefully, and it is generally called a radio and television tower. In addition to transmitting TV signals, it also sends broadcast letters ... "Lin Dilei was shocked suddenly, her expression in amazement as if she suddenly realized something terrible.
The comrades who had listened seriously with a learning attitude were startled by her expression.
Song Fei quickly asked: "What, what?"
Lin Dilei returned to her mind, unable to explain, and angrily said: "Come on, take out your mobile phone!"
The comrades-in-arms are unknown, but seeing Lin Dilei is so anxious, how dare not to do so, immediately pulled out his pocket and turned his pockets, and within a few seconds, all five mobile phones were presented to her in tribute, plus her own, There are two Huaweis, one Apple, one Samsung, one Xiaomi, and one oppo.
Qi Yan and Qiao Siqi watched quietly and calmly.
Lin Dilei looked at the mobile phone that piled up in front of her in an instant, crying and laughing: "Who asked you to give me, I can't unlock the lock screen. I let you all take it out and look for it yourself, is there a built-in radio!"
A word to wake up the dreamer.
Song Fei just wanted to smoke himself. Why didn't he think of it? Can't receive TV, broadcast!
I think there are all mobile phones in the impression. Song Fei opened the system tool folder-in fact, this folder is equivalent to his clutter room, all the mobile phone built-in chicken ribs that can not be removed and used, will be dragged here by him-rummaging for a long time, there is no Radio type icon.
Other friends are similar, first excited, then confused, and finally disappointed.
Only Wang Qingyuan ’s Xiaomi downloaded an fm radio app, but that is the Internet radio that listens to traffic, and the radio that listens on the band is two different things.
"Impossible," Luo Geng searched back and forth several times without hesitation, intellectually understanding that it was really not, but emotionally unacceptable, "My dad used his cell phone to listen to the radio every day. How come I don't have it anymore. Generation gap ?! "
Little friends have no way to explain, because they are also confused.
Everyone thinks that there should be a radio in the phone, but really, it is gone.
Only Qiao Siqi tried hard to go back to his mobile phone journey, and it seems to have found some clues: "Maybe it is really a replacement. My first mobile phone was in the fourth grade of elementary school. My dad bought it for me, and I flipped it back then. I can listen to the radio. I always listen to it. Later, when I changed my smartphone, there was also a radio, but I did n’t get the impression of the mobile phone changed in high school. At that time, there were too many things that the mobile phone could do. I listened to the radio, went to university, changed fruits, and various apps on WeChat and Weibo every day.
Certainly not all models of all brands of mobile phones will be castrated off the module function of the built-in radio, but if the mobile phone of Wusheng Class 1 is used as the sample of the sample survey, this is definitely the trend. However, if it wasn't for Lin Dilei to mention, they couldn't even think of such a thing-the times have evolved so fast that everyone has been chasing after new things, and they are simply not aware of what is changing quietly, Not even seen.
Just like the TV discussed earlier, you naturally use it, and naturally accept it to open and have programs, but if you think about it carefully, in fact it has unconsciously changed from no set-top box to an organic set-top box, from a stand-alone to a Networking has evolved from what you see to what you want to see and choose, and you can even start installing apps.
This change is so huge, the technological change behind it may be upside down, but when it comes to life, it becomes a breeze. For most users, the alternation of new and old technologies is a silent process, just like few people can accurately remember the time when they first used q 丨 q, the time when they first downloaded WeChat, or The time when Alipay was first installed. After waiting for God, they have become commonplace.
Dong.
The familiar radish knocking window sounded again.
The little friends who have not recovered from the blowdown of Snowflake TV and were hit twice by the death of the radio, did not respond for a while.
Dong dong dong.
Turnip was very anxious and hit three times in a row.
Song Fei walked to the ground floor, took out the flashlight from the backpack holding the corner of the shop, and then walked to the window, opened the blinds and cracked brightly-the window was empty, except for a radish that helped the note.
It seemed that there was no more singing, and the zombie should have returned to the hall to avoid the cold.
Turn off the flashlight, Song Fei quickly opened the window to remove the note, wait for the window to lock, and read it in place.
Is still the small characters of the previous Juanxiu. Inexplicably, Song Fei feels like Huang Mo's handwriting.
"What are they going to do? Wouldn't it be more scolding and more angry to really come down to fight group fights?" Zhou Lu asked a little nervously.
Qiao Siqile: "You are not saying that if they want to beat you, let them beat them, it is estimated that they heard your sincerity, and they were moved if they did not want to come down."
Monday black line, just wanted to say something, was interrupted by Song Fei after reading the note
"They said they wanted to come down and interview us."
My friends are surprised, it is already midnight, and in theory, it is not a particularly suitable time for guests.
"How to say," Song Fei asked everyone's opinion, "Let them come down?"
Everyone looked at each other, and they were unsure for a while.
Cooperation is one thing, face to face is another thing, although this is a bit of a villain, but the amount of food reserves upstairs can not be compared with downstairs, they will be shadowed for a lifetime if they do it once.
"Are you sure they only have six people?" Luo Geng looked up and asked Song Fei.
Song Fei nodded immediately: "Well."
Lin Dilei also said: "I testify, there are six."
"Then let them come down," Luo Geng looked at the little friends, with a tone of consultation, "Eight to six, we may not suffer."
Everyone thinks for a moment
"Row."
You can use a plastic bag to tie radishes, but if you really go down, it ’s the same as Song Feilin ’s before, and you can only tie your clothes. Fortunately, there were only four classmates at the end of class 2, so they were all neatly dressed. The two people who were stationed upstairs should have left nothing, so the fourth person just landed and the clothes rope was pulled back.
Song Fei brought them in as quickly as possible. The four guests were Zhao He, He Zhiwen, Huang Mo and Feng Qibai.
As Qi Yan closed the window and closed the lock, the number of classmates on the first floor increased to twelve.
Four people, Zhao He, stood by the window, still the boundary they stood after jumping in. They barely moved half a step, and their tension was obvious.
One class of eight people did not dare to take it lightly.
Twenty-four eyes face each other, a moment of awkward silence.
Song Fei is familiar on both sides, and he can only stand up when he sees it. Three meters away, Zhao He, who is the leading brother at a glance, asked, "Friend or Jackal?"
Zhao He was asked with a look of coercion.
He Zhiwen and Feng Qibai also did not understand.
Huang Mo smiled, her smile made her only inexplicably beautiful facial features: "A big river has a wide wave and the wind blows rice and flowers on both sides."
Song Fei grinned: "Friends come with good wine, jackals come with □□."
He Zhiwen and Feng Qibai glanced at each other, and suddenly one of them clamped Zhao He's arm.
Student Zhao gritted his teeth and said: "Relax, I can't bear it."
But why are there such hatreds in the world! ! !
After such a special opening, the atmosphere became alive. Although it is still inevitable to guard against each other, this kind of alert is more like a survival instinct in a virus crisis state, and malicious are two different things.
Without malice, you can live in peace.
Of course, it is time to build a deep friendship.
Four people were invited to sit on the ground floor. After a little glance at the environment, the students in Class 2 knew that this was the treatment of a guest.
The eight friends who were sitting around randomly picked up their mobile phones and came over. For a while, it was a little crowded and warm. The twelve people squeezed you next to me.
"Why are you all holding mobile phones?" Feng Qibai looked around strangely, and found that several people were holding their phones. "Aren't they disconnected from the network? Most of the night, playing stand-alone games?"
He does not mean that.
The sad thing was evoked again, Song Fei sighed: "Don't mention it, it's hard to see the light, and I think of the broadcast, but there is no mobile phone."
"We have." Feng Qibai said suddenly.
Eight small friends stared together: "Ah?"
"But it's useless." He Zhi asked the interface. At the same time, he took out the mobile phone with headphones in his pocket, unlocked the screen, double-clicked, turned on the radio, and handed the white ear wire to Song Fei.
Song Fei quickly took over and put the earphones in his ears, except for Zizila, there was no human language. Even if it ’s Spanish Arabic:
It ’s all galvanic, please try another station.

He Zhiwen raised his mobile phone and showed him the screen, but he said helplessly: "I've been tuning in. Hasn't it sounded the campus radio when the incident happened? At that time, I thought of using a mobile radio, but it was useless. Mobile The built-in radio is basically FM FM, which belongs to the ultra-short band, which spreads in a straight line and has a limited propagation distance. This band can only listen to local programs. "
"No," Luo Geng remembered the years when he was tortured by his father's radio. "My dad listens to fm all day and night, and there are news hookups."
He Zhiwen: "That is the second conversion after the local broadcasting center received the signal, and then broadcast it to the nearby area through fm FM."
Song Fei seems to understand: "No stations can be found in fm, and there is no signal from the TV. That means ... The radio and TV systems in our city can no longer function normally?"
"It may even be the whole province." He Zhiwen pushed his glasses. The term is a rigorous peculiarity of science and engineering men. "Although the propagation distance of fm FM is short, it is not necessarily limited to a city, and it can be found in many places Urban platform, so ... "
Needless to say what follows, everyone understands.
This is not good news, but after the disappointment of one after another, it is okay to be disappointed again. At least I do n’t have to worry about why I did n’t buy a mobile phone with a built-in radio, and I learned a lot.
"Classmate He, aren't you from the Department of Physics, why are you so clear about radio?"
He Zhiwen smiled coyly: "Hey, hobby."
The smile on the chubby face is more stern.
Song Fei lived to learn old, but wanted to deeply digest the other party's popular science about radio channels, but after re-talking the previous dialogue, I found a problem: "Wait, you said that you heard CCTV news through FM After the second transformation of the local radio and television center, how did the local radio and television receive these signals? It can't be FM, too. We have a vast river and mountain. How many relays do we have to go through one segment? "
"That's why we came to you." He Zhiwen felt very magical when he talked about it. He was originally worried that he didn't know where to start. This is good. It was a good thing to meet a class of diligent alumni. It ’s a matter of course,
If, I mean, if the country really did n’t give up sending information to us survivors, then there are two most effective channels, one is radio waves, and it must be the sw, the shortest transmission distance, short wave ; Another one is the satellite TV signal, which is transmitted from the still-operating ground signal to the base station, transmits the signal to the communication satellite, and then the satellite transmits the signal back to the ground. Both of these can be directly received without any transit. of."
"No if." Song Fei did not hesitate, "We risk going to be bitten to turn on the TV, that is, we believe that information will come."
He Zhiwen Wen Yan looked around all the students in Class 1, and found that the expression on everyone's face was basically similar to that of Song Fei.
He turned to look at his three companions, and received a positive look.
He Zhiwen took a deep breath and finally came to the meaning: "We, like you, are eager to know the information outside. But to receive short-wave signals, you must get a radio that can receive this band of signals, or directly A full-band radio is better. Otherwise, it ’s just a way to get a satellite pot with a TV, but no matter which one, I ’m afraid we ca n’t do it alone.

"So you guys want to cooperate with us?"
"Correct."
"Where is there such a radio or satellite pot"
"Not sure."
"..."
Song Fei was speechless, Bai was excited, just wanted to vomit and did n’t aim. Why did you say so much, but listened to Monday law and asked: "Can I listen to radio at level 4 or 6?"
The first class of friends shines, if the listening radios of level 4 or 6 are good, then there is no need to worry, there are certainly many teaching buildings full of them.
"No," He Zhiwen apparently considered this question long ago, "The listening radio we send out only has two bands, af campus radio and fm FM, and we can't receive others."
"How about car radio?" Qiao Qiqi suddenly interjected.
Eleven pairs of eyes looked at the past, this proposal is not surprising, but the thinking is very special.
He Zhiwen quickly recovered, thought for a moment, and replied: "It's not easy to say, I still have to see if the radio itself has this band. In addition, if it is our school's underground parking lot, even if you bring this band, I am afraid I want to receive it. Will be difficult. "
"Are you going to run into the underground parking lot and smash the glass?" On Monday, I couldn't think of any other tricks, unless I bumped into Dayun and encountered a confused egg that forgot to close the window or lock the door.
Qiao Siqi somehow: "My own car can be opened with the key, why do you smash the glass?"
All students: "Do you have a car at school?"
Song Fei: "Are you carrying the car key?"
Everyone does not look at Qiao Siqi, but Song Fei instead.
The latter embarrassed, quickly looked at Qiao Siqi, and replaced the explanation with a question: "Did you not escape to the dormitory with nothing, still carrying the car key?"
"Key mobile wallet, you can't forget these three things when you escape." Classmate Johns said that he actually found a key ring from the pocket of his pants. The top was simple, and he tied a dormitory key. Two of them should be home Keys, a simple car key to take out.
"What did you do to get a car to the school from a place outside?" Zhou Lv asked instead of all the friends. As a matter of fact, there are not many families who drive here locally. Their school style is relatively simple, and most of the students are still down-to-earth.
Qiao Siqi didn't feel anything, but suddenly he was guilty under the gaze of his friends, and he didn't speak very well: "Just go out to play on the weekend. It's convenient to go to the city ..."
Monday black line: "You don't have to grab a train ticket when you come home for the New Year, do you?"
Unexpectedly, Joskey shook his head: "No, no, my dad won't let me drive a long distance. The cars were bought here, and I ran in the city."
Monday's law: "After a long time, what car?"
Qiao Siqi: "Wrangler."
Monday's law: "Don't you in the city of four or five million off-road vehicles ?!"
Qiao Siqi: "I occasionally go to the suburbs ..."
Monday law: "The only thing that can cure me now is that you grab tickets with us before the winter vacation, don't tell me you don't need it."
Qiao Siqi: "I always book tickets for me directly at home ..."
Monday Law: "I am now rich with Qiu, I want to beat him, do you have one?"
All friends: "Bring, get on, me, everyone!"
