Why is there still radio broadcasting?

Radio programs are very rich, some people are used to listening to the radio, and there are many young people who are attracted to the past because of the content, although there is no radio but there is a mobile phone, ** Himalayan or dragonfly radio can be. ‍‍

Personally, I think that the radio can convey the warm texture of people's voices, and the sound effect is natural with the original material of the radio. ‍‍

Traffic radio is also an hour to broadcast several road conditions, each radio is also from time to time to update the weather conditions, news broadcasts are rotten streets, the national radio, central radio, provincial and local stations are available. ‍‍

There are also news broadcasts and economic broadcasts on provincial stations, as well as economic broadcasts, news broadcasts, and story broadcasts in provincial capitals, all of which have many high-quality programs. And the interaction with the audience is very strong, such as songs, emotional connection, emotional sharing, life sharing, legal advice and so on. ‍‍

Because of the history of decades and hundreds of years, people's habit of receiving information is not formed in a day or two, let alone erased in a day or two. ‍‍

This is something that many cold high-tech products can't replace. Another thing I personally experience is that the radio calms me down more than my phone! ‍‍

This can't just be said to be feelings, it's a kind of faith, a kind of remembrance. Those years that have passed cannot be ignored.

A few years ago, the popular health care product program was crazy for the elderly in the call radio station, and now there are more and more programs that tend to young people, and there are many popular **. ‍‍

A just right mood, a just right environment, just the right sound, the three just the right meeting, achieved a just right fate. ‍‍

Listening to the radio does not tire the eyes.

Emergency response, transmission characteristics of radio signals.

Traffic broadcasts in most cities will broadcast the 19:00 CCTV news broadcast, so pay attention to your local "traffic broadcast".

The radio is the receiver of radio broadcasts. A weak signal modulated by the high frequency input of the receiving antenna is amplified, converted and detected to an audio signal.

According to different needs, the radio can be combined with different components and lines. In the early days of radios, tubes were used, and transistors and integrated circuits are now commonly used.

Regenerative radios with simple circuits use only one transistor, while superheterodyne AM FM radios with complex circuits often use a variety of integrated circuits.

Reception principle:

Due to technological advancements, there are a lot of radio waves of different frequencies in the sky. If you receive all these radio waves, the audio signal will be mixed together as if you are in the middle of a busy city, and you will not be able to hear anything clearly.

In order to try to select the desired program, after receiving the antenna, there is a selective circuit, its function is to pick out the required signal (station), and "filter out" the unwanted signal to avoid interference, which is the "select station" button used when we listen to the radio.

The output of the selective circuit is to select the high-frequency amplitude modulation signal of a certain station, and it is not possible to use it to directly push the headphone (electro-acoustic), but also to restore it to the original audio signal, this reduction circuit is called demodulation, and the demodulated audio signal is sent to the earphone, and the broadcast can be received.

When I used to draw, I liked to listen to the radio at the same time: Foshan, Huadu, Guangzhou, Zhongshan, Hong Kong, Taiwan, Beijing and other radio stations, and later found a magical program late at night: Japanese customs program, English **, dreams, course programs, and German courses**!

The whispers are whispered in Spanish and Vietnamese. At that time, there was no Internet, and the spread of the program was very infectious!

My Cantonese, Mandarin, and Taiwanese accents were all self-taught from broadcasting. As a result, when I returned to Chaozhou, I only needed to listen to the teacher's lectures in Chaoshan dialect for about a month, and I basically spoke it.

So now let my child learn the language, I tell him to listen more, listen carefully and repeatedly, it doesn't matter if he doesn't understand, haha.

After the radio broadcast went into the middle of the night, after eliminating a large section of advertisements and news, you can also listen to various stories about the joys and sorrows of the troubled world.

One of the radio programs is very impressive to me, that is, I can call in every night to tell the story of a very tragic fate, not only the host is in tears, but even the people who listen to it are crying, and the later program is getting better and better, but in the end because the host is overly depressed, it was canceled.

I was only a teenager at the time, but I quickly realized that you should not turn your grief into a river and drown yourself if you drown others.

Can you add, I don't quite understand it.

This ancient "Feige" brand vacuum tube radio, which has puzzled telecommunications experts, was accidentally discovered by two children while playing in the attic of their home in northern Georgia, USA.

According to their mother, the radio originally belonged to her father, but since 1934 it has been abandoned in the attic and never used again. "When my two sons found the radio, they plugged it in to see if it still worked. The mother, who asked not to be named, said.

The ancient radio was able to receive the radio broadcasts of the time.

The investigation is still not complete, but according to some scientists involved in the study, this radio is more than half a century old, and it can indeed receive the signals of the radio broadcasts of the year and rebroadcast it.

I've heard one of the news reports, and I'm sure it's live, definitely not an audio tape. A scientist said. "It's a radio that really picks up the broadcasts of the past, and it's unique.

We had put a batch of fifty dollars worth of state-of-the-art receiving equipment around the radio, but only that radio could receive the broadcast, and our equipment could not even receive a single signal.

Why is this happening? We still don't know, but those broadcasts about the situation of that year, like the situation before World War II, the dynamics of the film industry, and the Great Recession, are absolutely not fake. ”

Broadcast: Widely broadcast, widely disseminated.

Radio and television stations broadcast audio and image programs to a wide area through radio waves. Cable electricity broadcasts audio programs through wires, also known as Minhu broadcasting. It also refers to the programs broadcast by radio stations and cable telecommunications.

Broadcasting refers to the means of disseminating news that transmits sound through radio waves or wires. The transmission of programs through radio waves is called wireless broadcasting, and the transmission of programs through wire bridges is called cable broadcasting. Guangheng was born in the 20s of the 20th century.

The advantages of broadcasting are that it has a wide range of objects, rapid dissemination, diverse functions, and strong appeal; The disadvantage is that it is fleeting, listening sequentially, you can't choose, and it is difficult to listen if you don't understand the language.

The radio program of a radio station is transmitted via radio waves.

When broadcasting on a radio station, the announcer's speech and the sound (sound waves) of various radio programs are first transmitted into the air through the transmitter and the transmitting antenna, and then turned into radio waves into the air, and after being received by the receiving antenna of the radio at home, the radio restores the radio waves into sound waves, which are then amplified by the loudspeaker.

In this way, we will hear the radio broadcast!
