After chatting for a while, Liu Fang's accumulated questions were temporarily asked, and he changed his words and talked about the association itself: "Everyone, I don't know how many members our association has now?" ”

This question made Sam and the others feel a little embarrassed, and he sneered: "Originally, there were many members, and at the peak there were more than 8,000 members, but now, the total number is only about 200, and most of them are silent on the radio, and they are reluctant to come out and bubble.

Liu Fang was curious: "What's going on?" Where have the former members gone? ”

"A handful of them are too busy with work to have the time and energy to continue tinkering with radio, while the vast majority opt out because their interest has shifted from radio to computers."

Liu Fang couldn't help but move when he heard the word computer: "Does a computer have such a great charm?" ”

Sam replied without hesitation: "Of course there is, it is said that those guys with strong computer technology can hack into other people's computers at will, spy on other people's privacy, and even use computer technology to make illegal profits for themselves, this kind of insolence hiding in the shadows is indeed very attractive, especially those who have dark hearts, there is no resistance to this, and some people think that computers are the future development trend of mankind, and the reason why they choose to study computer technology, It is to be able to have a place in the world of the future. ”

Liu Fang then asked the question he wanted to figure out the most: "What is a computer?" How is it constructed? ”

Sam was slightly stunned: "Listening to the question you raised earlier, you know radio technology very well, in that case, how can you not understand computers?" They're all electronic devices, you can't have heard of them, right? ”

Liu Fang said honestly: "I said before that I was relatively poor and couldn't afford a computer, but I heard someone mention it, and I don't know much about the specific situation, and I hope Mr. Baron will help me explain it." ”

Sam sighed: "So that's what happened, I'll explain it to you now, a computer is a machine that can perform high-speed calculations, it not only has numerical computing capabilities, but also logical operations, and also has memory storage functions, it is mainly composed of hardware and software, you can think of it as a strengthened version of the human brain." ”

Liu Fang showed a curious expression: "You just mentioned hardware and software, I don't know what they are?" ”

"Hardware is mainly composed of integrated circuits, chips, displays, keyboards, as for software, it is a kind of coding program, is a collection of computer data and instructions composed in a specific order, unlike hardware, software has no physical form, it is just a combination of letters and symbols, mainly responsible for coordinating and controlling hardware to work."

"Computers are amazing!"

Sam couldn't help but feel nervous when he heard this: "Poor boy, don't you want to leave the association and transfer your interest to the computer like those people?" ”

"That's impossible, first of all, I don't have the money to buy a computer, and secondly, I don't know anything about computer technology now, so naturally I'm not interested."

Liu Fang said this, but he thought in his heart: This thing sounds really amazing, but unfortunately, I even have a problem eating, so I have the opportunity to contact the computer?

"Very well, poor boy, I hope you will resist the temptation of computers and join us in defending the last glory of the Radio Amateur Society."

As soon as Sam's voice fell, a female voice rang out in the channel: "Please note that everyone in this channel is the U.S. Information Administration, after five minutes, we will block this channel and all other unauthorized channels for two hours, which will cause you any inconvenience, and please understand, if you still have unfinished communication work, please complete it as soon as possible, so as not to cause unnecessary losses to you." ”

Sam got angry when he heard this, and he yelled in the channel: "Fuck! You have to block the signal every three or five times, and you don't let people live?! ”

Liu Fang was quite curious about this: "Baron, why does the government block the signal?" ”

Sam said angrily: "Usually for some experiments, in order not to let irrelevant people affect the results of the experiment, they will block the signal, but in my opinion, this is simply redundant, we are just radio communication, where will it affect them to do experiments?" ”

Liu let out a sigh of relief, and said in his heart: Maybe the government wants to use these blocked channels for secret communication through some special means.

"Poor boy, today's conversation is very pleasant, I hope you can show up on time in the channel tomorrow and continue to talk to us."

Liu Fang was so happy, he felt that he had gained a lot, and he was reluctant to leave the organization, so he nodded: "No problem, tomorrow at one o'clock, I will show up on time." ”

"Okay, then it's settled, poor boy, that's the end of today's exchange, we'll see you tomorrow."

Sam turned off the radio equipment after speaking, but Liu Fang didn't do it, because it was still a long time before dawn, Liu Fang's excitement had not passed, he wanted to take advantage of this time to continue to study radio technology, anyway, he was using a military radio, even if the civilian channels in the United States were blocked, he could also receive radio signals from other regions.

"Drip-drip-dad-da-da-d-da-d-d-"

When Liu Fang was fiddling with the equipment, a very regular sound suddenly sounded in the earphones, he was slightly stunned, and said to himself: "This frequency is very similar to Morse code, who would use such a backward way to communicate?" ”

Liu Fang stopped what he was doing, he took out a pen and paper, and recorded everything he heard.

The sound lasted for about five minutes before stopping, and Liu Fang was stunned as he looked at the dense content on the homework book.

Anyone who knows a little bit about radio technology will not know what Morse code is.

Morse code belongs to a relatively backward mode of communication, and in history, in addition to telecommunications and telegraph companies, the most is the military or spy agencies, because this communication method itself has very good encryption characteristics, as long as it is slightly improved, the secrecy effect will become stronger.

"Is it the military or the spy? Anyway, let's translate them into text first. ”

Liu Fang felt that being idle was also idle, since he had a lot of time, it was better to find something to do for himself, at present, it seems that this mysterious radio wave must be extraordinary, and it is good to translate it and see it.
