In the 1960s, when the cultural life in society was very monotonous and lacking, people's spare life was more reading and listening to radio. At that time, I was still young, about 11 or 2 years old, reading novels and reading large books was still very difficult, and many words were still unknown, so listening to the radio is the most convenient for us, it should be said that it is us At that time, the best way to obtain various social knowledge.
But when I was little, there was only an old-fashioned Japanese tube radio at home. It may be that it is too old, and every time it is opened, it will emit a buzzing electric current and a crunchy murmur, just like a person who is old and suffers from asthma. He coughs constantly, especially if you listen to novels at noon every day. During the hookup, teacher Yuan Kuocheng ’s wonderful storytelling. When you held your breath and heard the flight investigator Xiao Fei in the storytelling "Plain Gunshots", in order to save his comrades, he risked his life and ran into the county town of the enemy occupied area to buy medicine. Found by the Ghost Gendarmerie, at the moment of chasing on a motorcycle, Xiao Fei's life and death were at a critical juncture, when the gripping life was hanging on the line ... The old radio suddenly didn't want to at this critical moment, when you were in a dangerous situation. I have come back to God, and I'm really anxious to fire up the house, and you are so angry that you have smoked. You have countless times of such encounters, and every time my spirit has been destroyed.
By chance, I saw the students of the Youth House Technology Group installing ore radios, so I also had the urge to make a radio myself, so I asked for some money from my home and bought the equipment from the electronics store. The material of the ore radio, a small glass tube, the scientific name is the detector, there is a magical, cinder-like ore and a probe, plus a high-impedance earphone machine, a variable capacitor, a number of wires, enameled wire, etc. Then, find a wooden box with original nails, paint a layer of sky blue paint on the outside, and then install a bakelite panel on the surface, install these materials on the panel according to the principle described in the book, and make a piece of wire I put an antenna and pulled it to the roof. After debugging, the sound came out of the earbud machine and I could actually listen to the radio. I felt so amazing at the time. I saw the work I assembled successfully for the first time. The probe's exploration on the small ore like coal cinder particles can actually listen to the radio and music, which makes me, a teenager just ten years old, so fresh and prickly Do n’t mention much excitement, so listen at noon, at night, and even often lie on the bed. The little ore radio, in addition to listening to domestic broadcasts, sometimes even hears the sound of Moscow Radio. At that time, it can be regarded as a The enemy broadcast. I listened to this crude ore radio for a long time until I went to middle school.
During the Cultural Revolution, semiconductor technology has developed rapidly, gradually replacing those bulky tube radios. Semiconductor radios are light in weight and small in size. They use small transistors to replace the original bulky tubes, and it does not need to be plugged into the power supply. You can carry it everywhere and listen everywhere with a battery. In the 1950s and 1960s, the radio was an important property for ordinary people's families. Many of our middle school students at that time were fond of listening to radio broadcasts. However, buying a radio did not have this financial ability, so we could only save some money and assemble it. There were really a lot of people who had this kind of hobby in those days. Radio enthusiasts can be found in many classes. After school, people often discuss the knowledge of installation and buy a bunch of diodes, transistors, and speakers with the pocket money given by their parents. , Magnetic rods, variable capacitors, resistors and other components, learn to assemble by yourself according to the circuit diagrams introduced in the book. I had installed single-tube, two-tube semiconductor radios at that time, and I still enjoyed myself, becoming more and more addicted.
In fact, the installation is simple, but it is not a simple matter to install a decent semiconductor radio, because it is all self-study, and it can only be explored a little. Sometimes, each part is connected according to the circuit diagram. But it just doesn't sound, and I can only come back to check it section by section. Welding, welding and tossing have been troublesome, and we have been struggling. We often get hot hands when we touch the pipe, and burn the pipe. Sometimes we make transformers on the circuit board. Even frustrations such as smoke, but the more this is the more fascinated, often forgetting to eat, forgetting to sleep, thinking about wasteful sleep. After a long period of hard work, I finally assembled a four-transistor semiconductor radio, and bought an old radio casing in the flea market. I polished it with sandpaper and repainted it. After installing it, I put it Placed on the square table for dinner at home. In this way, when I eat, I can listen to a storytelling series, a radio drama, or a ball game broadcast while eating. Compared with the ore radio assembled at the beginning, it is really a shotgun for the cannon. I have really assembled this semiconductor With a sense of accomplishment, this radio has been with me all the time to hear the job.
It wasn't until the early 1980s that I spent nearly two hundred yuan to buy a two-in-one radio receiver with sing-along. But my childhood experience made me still unforgettable. Although the material standard of living was very low at that time, my spiritual life was very fulfilling. The poor life stimulated our fighting spirit. Instead, we learned a lot of life skills. Brought us a lot of fun in life ...
Because I was fond of radios as a teenager and I learned a lot from the radio, I later bought a lot of various radios, such as record players, radio cassette recorders, and all-channel radios, after working for a little extra money. , To the current Internet radio, etc., a lot of collection, can be regarded as a hobby in life. After so many years, although I moved several times, I did not want to throw away the four-tube semiconductor radio that I personally assembled when I was a teenager, but its appearance has been somewhat incomplete after years of dust ...
