We Live In Nanjing

  Chapter 3 Poplar

  Meihua Villa Zhongqin Garden, 66 Mufuyuan Street, Qinhuai District.

  Here is a one-hour walk to Zijin Mountain and a ten-minute walk to Crescent Lake. There are mountains, waters and city walls. It is a treasured land of geomantic omen. The housing price of the community is more than 30,000 yuan per square meter.

Bai Yang rode a bicycle quickly across the road of Alfalfa Garden Street, jumped under one street lamp into another street lamp, and then turned left to enter the community entrance guard. When rushing through the speed bump, the wheel was shaken in the air, and then it stopped heavily. In the surprised eyes of the security guard, he slipped into the night and disappeared.

  "You ride slowly—!"

  Uncle security poked out his head and shouted.

   "I know, Uncle Cai!"

  He is in a hurry.

The next night’s self-study will be at half past ten. It’s about eleven o’clock when riding a bike all the way home. The high school life is always so tight. My mother asks Bai Yang to go to bed before twelve o’clock every night, if he wants to do something before going to bed. What, then you must go home as soon as possible.

  The home is in Unit 2 of Building 11. When entering the community, turn left for 20 meters.

  Eighth Floor, 804.

  Bai Yang parked his bicycle downstairs and locked it, and then carried his schoolbag all the way upstairs. The voice-activated light in the corridor was lit from bottom to top to the top of the building the moment he stepped into the unit door.

Jumped to the eighth floor in one breath, Bai Yang took out the key to open the door, put down his schoolbag in the hallway to change shoes, the light in the living room was still on, but at this time the father and mother were already asleep, Bai Yang took a look at their bedroom. Sure enough, the door closed tightly.

  The supper prepared by my mother is usually kept warm in the rice cooker, and the rice cooker is placed on the table with electricity.

  If Bai Yang comes back from self-study late and is hungry, then there is something to eat.

  Supper usually consists of noodles or rice. Baiyang does not go home for dinner, so my mother will keep a separate portion of the dinner and put it in a rice cooker to heat it.

  He uncovered the pan, hot stir-fried noodles.

   Bai Yang tried to touch the bowl, but it was not too hot, so he picked up the bowl and returned to his room.

   "Xiao Yang?"

  As I passed my parents’ bedroom, my mother’s dazed voice came across the door.

   "Well, I'm back."

   Bai Yang replied.

   "Oh, come back, go to bed early."

  Mom fell asleep again, and Dad’s snoring was as loud as ever.

  Bai Yang returned to his room with a supper. His room was not big. The door was squeezed out by the single bed and the wall. The desk was against the bay window. To the right of the desk was a tall bookshelf. The bookshelves were full of teaching assistants.

  Three times, five times, and two, after finishing the supper, wiped his mouth, Bai Yang took a deep breath, took out his mobile phone from under the table and took a look at the time.

  11:30 in the evening.

Bai Yang sat up straight on the chair, pulled the curtains, opened the lamp, and solemnly took out a roll of toilet paper and placed it on the table. No matter what happens next, it’s always right to put a roll of toilet paper first. It was quiet at night, everything was silent, a single young man, alone, he had to do some handicrafts that were not convenient during the day.

  From this moment on, he is about to change his identity.

  In addition to the third year of high school, he has another identity—

  Old color batch.

of course not.

  ·

  ·

  ·

   is ham.

  What is ham?

   Ham is HAM, its full name is: amateur radio enthusiast.

  Poplar reached out his hand and took off the plastic sheet on the bookshelf, and slammed it, revealing the black radio station underneath.

  ICOM725 shortwave radio station, looks a bit like an old-fashioned CD player from the 1980s.

  The family heirloom left behind by the old man.

  Old antiques that can enter the museum.

He leaned forward and turned on the external power supply at the other end of the bookshelf, and pressed the POWER button on the radio panel. The radio started to be powered on, the light yellow old-fashioned LCD screen and the small level meter lit up, the channel stopped at 7.2750MHZ, and the poplar was on the jack. Plug in the earphones and hand microphones respectively, press the SSB button to enter the single-sideband communication mode, press the TUNER button to turn on the antenna tuner, after a few seconds the tuning is complete, the green light is on, and then slowly turn the **** to adjust the frequency.

  Fast action, at this moment he resembles Yu Zecheng, an underground party member in "Latent".

  Of course, it is also like an old man listening to the radio with a radio before going to bed.

  Tonight, Bai Yang will have the first long-distance contact in his ham career.

The so-called radio communication is actually looking for someone to talk, but the biggest difference between it and a mobile phone call is that you don’t know who you can contact, and you don’t know where the radio waves will be reflected by the ionosphere over tens of kilometers. , The radio station has no phone number, no operator, no fiber optic cable across the ocean, and no one-to-one dialing. In human terms, this is the serious "calling basically depends on roaring", but the roar is modulated and emitted by radio waves. Go out, and then be reflected by the ionosphere to a hundred and eighty thousand miles away. If someone can hear your roar, they will also roar back.

  Because of the limited equipment conditions, it is quite difficult to use shortwave to communicate over long distances. In jargon, this is called an expedition, and the abbreviation is DXQSO. Even for experienced old hams, DX failure is common.

In order to try tonight, Bai Yang climbed up to the roof of the building in the afternoon and confirmed that there was no problem with the antenna. When my father was young and frivolous, he set up two antennas on the roof of the building, a six-meter whip, and a DP antenna. Less complaints from neighbors.

  If nothing happens, he can contact radio stations in Russia or Europe on the 14.195MHZ frequency band after 8:30 in the evening.

   Then greet foreign friends and tell them that they are from CHINA.

  Poplar turns the knob, and the number on the LCD screen jumps.

  14.195 MHz.

  Bai Yang wore headphones to listen for half a minute. No one was speaking in the channel, so he pressed the TRANSMIT button on the microphone, and the green light on the radio panel turned on.

  This is the sending status.

  Bai Yang took a deep breath. As an illegal young HAM who has not yet taken the B certificate and has no qualifications, he called out the first call in his ham career:

  "CQ! CQ! CQ! ThisisBG4MXH, Bravo-Golf-Four-Mike-Xray-Hotel, callingcqandwaitingforacall!"

His voice will be modulated into regular radio waves in the radio, and then launched into the air by the **** inside the antenna. In the brightly lit Qinhuai District of Nanjing City, it looks like someone has thrown a small stone into the sky, wagging the naked eye. Invisible ripples, spreading in all directions at the speed of light, were reflected to the horizon at a height of 50 kilometers in the ionosphere, across large rivers and lush virgin forests, and were heard by everyone who was on this channel.

  "CQ" is a common phrase in all radio communications, meaning SEEKYOU.

  Similar to "Is there anybody? Is there anyone? Anyone?"

   and BG4MXH is his call sign.

  The above call translates into "Hey! Hey! Hey! This is BG4MXH! BG4MXH is looking for someone to chat! I am waiting for your reply!"

In China, amateur radio is a strictly controlled hobby. If you want to use a radio station to communicate, you must have complete documents. Operators need to pass an exam to obtain a license. Each legal radio station will have a unique call sign, just like people’s. The ID number of the IC725 in Bai Yang’s hand is BG4MXH. The letter B at the beginning represents China, and the letter G represents the level of amateur radio — Bai Yang’s is a three-level station, so it is G, and the number 4 represents the region, Jiangsu area The callsigns are all 4.

  Of course, there are also illegal radio stations without a call sign, which are called black stations.

   is like a black household who has not registered.

Bai Yang’s radio station was left to him by his father. Father is an old ham that has been cured for 20 years. He once served at the Guantong Station of the North Sea Fleet. Dad was a master of ham circles in Nanjing, a serious technical tycoon, and finally withdrew from the arena.

  In Dad’s words, where is anyone playing this these days? Isn’t it good to use WeChat to chat?

  "CQ! CQ! CQ! ThisisBG4MXH, Bravo-Golf-Four-Mike-Xray-Hotel, callingcqandwaitingforacall!"

  Bai Yang called again, and then waited a little nervously for a response.

  He hopes that another person’s voice will sound on the channel in a few seconds. It may be a call sign starting with J or R, from Japan or Russia.

  But there is still no answer in the channel, only boundless white noise.

  Bai Yang is a little disappointed, what is wrong?

But this is also the expected result. Shortwave communication problems are actually normal. Any factor may lead to failure. The radio wave itself is unstable, and the ionosphere is also unstable. Two uncertain things are mixed together. It would be a **** to be able to get a definite result together, not to mention the fact that the electromagnetic environment of the outside world is becoming more and more complicated, the interference everywhere in the city, an electric car is an anti-radiation weapon for the radio station.

  Either there is no one on this channel, so he didn't respond to any calls.

  Baiyang turned over the phone, and other people clearly said that 14195 is a vegetable market.

  He found the post again.

  Look at the time.

   Damn, 2012.

Dad is right. There are fewer and fewer people playing radio, and even fewer people playing shortwave. At present, there are still living people in the UV frequency band. The car friends in the city rely on this to discuss where to go on weekends. No one has done such a time-consuming and laborious thing as long-distance communication with shortwave radio.

  So Dad uses this station as a radio.

Today in 2019, few people can feel the romance of radio communication. No one wants to set up a ten-meter-high antenna to send their voice to all over the world. This thing is too complicated, tedious, and slow, even as an amateur Hobbies are not interesting enough or exciting enough.

  More and more old HAMs are retreating from the arena, and Dad is one of them.

  Poplar increased the power from 2W to 5W, and tried to call again.

  There really is no one.

  The channel is empty.

  When the old man was young, some channels were as lively as a vegetable market, and radio waves from all over the country converged in the night sky and flew around the world.

  Now even the people in the vegetable market are astigmatized.

Bai Yang slowly turned the FM knob, and the number on the LCD screen changed little by little, from 14.195MHZ to 14.120MHZ, and then to 14.125MHZ. He wanted to try his luck, maybe someone would be talking on other channels. ?

  14.126MHZ.

  14.128MHZ.

  14.130MHZ.

  Poplar supported his head, listened to each channel for more than ten seconds, and then turned the knob.

  14.131MHZ.

  14.132MHZ.

  14.133MHZ.

  He is a traveler who walks alone in the desert, and he can't even see the second one of his kind.

Bai Yang sighed. Tonight’s communication failed. He watched the radio for a long time, dialed the radio FM knob, turned the **** around, and turned it over again, like playing a radio, the red TX indicator was always on. The numbers on the LCD screen jumped rapidly.

  He was taken aback suddenly, and his fingers stopped.

etc!

  White Yang carefully turned the **** back slowly, frowned, and listened attentively. In the noisy noise, some people were talking vaguely, not knowing whether they were singing or chanting.

  Someone!

  He glanced at the channel subconsciously.

  14.255MHZ.

  After tossing all night, Bai Yang finally met the second person.

   is still a girl.

   Bai Yang waited for the other party’s voice to stop and began to call: ""CQ! CQ! CQ! ThisisBG4MXH, Bravo-Golf-Four-Mike-Xray-Hotel! callingcqandwaitingforacall! "

   There was silence for a few seconds in the channel.

   Then a surprised scream erupted from the headset:

  "Alive?"
