"Rustle... First of all, let me tell you what an amateur radio ...... is."

The beautiful voice of VBB continued to come out of the speaker, and a new world was displayed in front of Lin Hong.

It turns out that there are different types of radio stations in the air, according to different wavelengths, divided into multiple frequency ranges, and there are unified regulations in the world, how many megabytes to how many trillions are only allowed to be used for what to do.

For example, the big radio stations have their own fixed frequencies, and others are not allowed to preempt their frequencies.

And there is such a small group of people in the world, they are very passionate about radio technology, and they do not set up their own radio stations for profit, and they are called amateur radio enthusiasts, and they are called "ham people" in China, because this is translated literally according to the English ham.

As for why it is called "ham", there is an unknown allusion to it, which is a long story, but simply put, the word originates from the call sign of an amateur radio society at Harvard University in the United States.

The management of the "ham family" in various countries is very strict, and individuals are not allowed to set up radio stations to receive or transmit signals without permission, and must apply for the corresponding amateur radio license in accordance with the specified process, and after obtaining the world's only call sign, they are allowed to communicate with other "hams" on the line.

Because the frequency band is a limited resource, people all over the world are using it, so the use of the frequency band has been divided very precisely, because the "ham family" to the advancement of radio technology is very huge, the international special frequency band for the use of the "ham family" is specially set aside.

As Lin Hong operated before, 7 megahertz to 7.01 megahertz, this frequency band is one of the entry frequency bands for beginners, and "hams" all over the world are crowded on this narrow frequency band, so it is also the most crowded and lively frequency band.

The call sign is the only identifier that "ham" identifies each other, just like the name, with this, everyone can distinguish each other.

Call signs are not arbitrarily named, and there are so many hams in the world that if they all had their own names, it would be a huge confusion, as was proven when radio was just developing.

Therefore, the International Telecommunication Union later made unified regulations on the call signs of radio stations in various places, and the short call signs contained important information such as the country, the operation level of the station, and the region where the station is located. Only the last few letters are the nickname code of the individual.

Moreover, after so many years of development, the communication between hams has formed a set of conventional call etiquette and call terms, such as the beginning of CQ, which means that the call is being made; When calling others, you should first report your own call sign...... Wait a minute.

Lin Hong and VBB chatted until nearly three o'clock in the morning, and the other party was commenting all the time, and Lin Hong was listening and asking questions.

"Rustle... Ah Huang... I'm going to take the math test competition at school tomorrow, and I won't be able to get up in the morning if I don't sleep, so let's talk about it today... Ah~~ In addition, these basic knowledge, it is recommended that you read more amateur radio magazines, which are generally explained... That's all for today..."

VBB was already yawning, and after the two sides said goodbye to each other, she went offline.

Although Lin Hong was a little reluctant, he couldn't help it, after all, VBB is not like herself, she doesn't have to sleep day or night, and it's rare for her to talk so late today.

Today he opened his eyes again, he didn't expect that there were so many exquisiteness in the small radio waves, fortunately he met VBB today, otherwise he didn't know how many jokes he would have made.

In the end, VBB let himself read more amateur radio magazines, which reminded Lin Hong of Lao Xu's other room, which he remembered was also a few large boxes full of books and newspapers.

Lin Hong hurriedly went to the workbench to pick up the flashlight, and then ran to another room, the rooms were not locked, most of the things in it were some sundries, Lin Hong bypassed a few large wooden boxes, and came to the innermost.

"This is it."

In front of his eyes, three huge cardboard boxes were stacked on top of each other. Lin Hong remembered that the last time Lao Xu Tou found the "China Radio" magazine from here.

When he opened the box, the box was full of all kinds of magazines, and Lin Hong took out a copy casually, which said "Electronic World", and a large transistor was printed on the cover.

He put it back in and took out a new copy, and the result was Radio and Television.

It's really inconvenient to extract like this. So, Lin Hong started from the side, took out these magazines one by one, and after taking five or six copies in a row, he finally saw a copy of "Amateur Radio". He set it aside, then continued to clean it up, eventually clearing the entire box, finding a total of more than two dozen magazines and books related to "amateur radio".

He restored the magazines in his box, then took them back to Lao Xutou's room, turned on the electric light on the workbench, and began to read at a very fast speed.

He looked at the clock on the wall, it was nearly four o'clock, and he didn't have much time left, and he was going to finish reading all the magazines before dawn.

Under his deliberate acceleration, for a while only the sound of scrolling through the book was heard. Except for a few articles about production, most of the content is relatively rudimentary, and many of them are literacy knowledge, so Lin Hong read it quickly.

By the time the sky was just dawning in the morning, he had basically finished reading more than 20 magazines.

He moved his aching neck and put the magazines back in their place.

After several hours of emergency raids, he really had a more detailed understanding of the "amateur radio". Whether it is the history of the "ham clan" or some basic common-sense concepts, he has a corresponding memory in his mind.

People have an inexplicable fear of unknown things, so Lin Hong instinctively felt a worry in his heart when he looked at the knobs and strange letters on the radio station, for fear that he would break things if he accidentally moved.

And now, he can understand most of the signs on the panel, and he has a general understanding of the function of many knobs on them, and he suddenly realizes that this thing is just like that, in fact, it is only a little more complicated than those radios.

His mind was a little noisy at the moment, so he got up and opened the door and went into the courtyard. Then began to stand up in the courtyard in the trisota.

This is what his master explained before, and this three-body pose has to stand every day, especially when it is just dawn.

Concentrating and calming, his eyes slightly closed, looking ahead, Lin Hong emptied all the chaotic thoughts in his mind, and constantly adjusted his posture according to the main points of the three-body pose, and finally reached a state that made him the most comfortable.

The sun slowly rose from the east, and the sun shone on the young man in the middle of the courtyard, and I saw a confident look shining between his eyebrows.
