Countercurrent 1982

Chapter 152 Electronic Enthusiasts

The Four Pailou is located not far from the north of the Drum Tower.

After riding for less than 10 minutes, Duan Yun came to the Youfang Lane mentioned by the mustache.

There was indeed a hardware store at the entrance of the alley, and at the door of a bungalow facing the street next to the store, there was a sign of 'Home of Radio Enthusiasts in Daxing City'.

In the era of advanced communications in the later generations, radio was a very small hobby, but in today's era of lack of entertainment and high thirst for knowledge among the public, many people are still very interested in electronic radio, although it cannot be compared with popular ones. Compared with folk literature societies, in many larger cities, there are also government-approved folk literature societies.

The so-called radio enthusiasts are not specialized in radio work, but they have mastered certain electronic technologies to learn, make, and use radio, so that they can learn, apply, and master radio to enjoy the fun of it, and realize the simple problems of life, study, and work. .

After joining, you must first learn the basics of radio and master the basic operation of Morse code. First, you should focus on listening. If you want to get in touch with a real radio station, you can only join this government-approved organization first.

Daxing is a national key energy-based large city with a large population base and many radio enthusiasts.

At the beginning, the association was just established, and every Sunday when the association was active, only some internal members occasionally exchanged some second-hand electronic components with each other, and as more and more members of this radio, people who exchanged electronic components and even old electrical appliances It has gradually increased, so that now, not only members trade and exchange various components, but there is even a trend of developing into a second-hand electronic trading street. Many local citizens and electricians also come here to buy and exchange needed electronic components. .

Since this year, the second-hand electronics trading in Youfang Lane has been small and large on Sunday, and many electronics enthusiasts have also brought out some cheap and high-quality small electrical appliances made by themselves to sell here.

Although there are some experts in electronic technology who sell self-made small appliances here, in general, the small appliances they design are not high in technology, such as bicycle lights, adjustable fans, and advanced and complicated appliances need to find experts. Made to order.

Since it is a pretext for internal communication among members under the name of the radio association approved by the government, the industrial and commercial departments have not managed this kind of second-hand exchange activities.

Every Sunday afternoon, Youfang Lane is very lively. Most of them exchange some electronic components and second-hand goods. The things are very miscellaneous, and some electronic components are even products from the 60s and [-]s.

Although these things are cheap, they are of no use to Duan Yun, so he just glanced at them and left.

After looking at several stalls one after another, he found a speaker selling speakers in front of him.

This immediately aroused Duan Yun's interest. He also wanted to develop the audio market, so he stepped forward to watch.

The stall owner is a middle-aged man in his 30s, wearing a pair of high myopia glasses. The speaker he brought is not big, only about [-] centimeters high, and the chassis is a bit rough in workmanship.

However, there were a lot of onlookers at this time, and some of them were obviously wealthy masters, dressed very fashionable. Duan Yun even saw a few young people riding sidecar motorcycles and happiness 250 at the entrance of the alley!

You know, people who can ride this kind of motorcycle these days are definitely rich people. Riding on the street is quite cool. Even if the future generations drive a good car like Mercedes-Benz and BMW, the rate of return will not be comparable to that of this motorcycle back then. On par!

As the so-called rely on the mountain to eat the mountain.

After all, Daxing City is an energy-based city, and in the 80s, there was a serious phenomenon of private mining and excessive mining in mining areas. Many local gangsters and local snakes made their fortunes by opening small coal mines. The prototype of the boss'...

In addition, by blocking roads and setting up roadblocks, many villagers on coal transportation lines also made a lot of money. It was not until 1983 that the crackdown began, and the situation improved.

Therefore, there are still quite a few rich people in Daxing City, although many people's methods of making money are somewhat shady...

In addition, Duan Yun also found that the young nouveau riche are also dressed in a very fashionable way. There are a few fancy small speakers on the sidecar of the motorcycle, and there are colored lights on the front and rear, which are obviously not original parts.

Obviously, these people probably come here to look for 'black technology', after all, there are many 'fun' things here.

"Brother, come and have a look at my speaker, it's designed for imported speakers, the sound quality is absolutely hot, not worse than imported ones!" The middle-aged man wearing high myopia glasses shouted to several young people passing by.

"Can your stuff compare to imported speakers?" A young man wearing sunglasses and flared pants suddenly became interested and said, "Then play a song and I'll listen to it."

"Wait." Hearing this, the middle-aged man connected the speakers he brought to the tape recorder, and then connected a homemade wooden box with eight AA batteries behind the case.

"Bounce Kaka! Bounce Kaka!"

After turning on the switch of the recorder, fast-tempo disco dance music came out of the speakers.

Duan Yun just listened for a while, and he felt that the speaker was very ordinary, and it seemed that the speaker shell was too thin. After the volume was increased, the shell trembled slightly, resulting in a lot of noise.

In fact, it is normal for these so-called electronic experts to design such a speaker. They have some understanding of electronic technology, but they are laymen in acoustics. Most of them learned the circuit principle of the speaker through some magazines and materials. Just make a simple finished product in a hurry to make extra money, but this kind of thing is obviously not special, and it will not be favored by music enthusiasts.

"It's really boring... What a crap, it's far worse than my Sanyo tape recorder..." Sure enough, after listening to it for a while, the young man shook his head and walked away.

"Brother, don't go, my speakers are cheap, the price is easy to negotiate..." Seeing this, the middle-aged man hurriedly stepped forward and said, "The power of my speakers is 8W, and the imported ones cost at least five or six hundred, so I'll sell you two hundred and five... "

"roll!"

"..."

Duan Yun smiled and shook his head when he saw this scene, then turned and left.

Just after walking not far, Duan Yun saw a group of people talking about something around a tall young man.

After taking a look inside, Duan Yun was completely stunned.

It turned out that the tall young man was holding a circuit board in his hand at this time, and there was a NE555 chip in the middle of the board!
