Introduction to the History of Radio

The history of radio begins with the discovery of radio waves by James Clerk Maxwell in 1864. It was not until the late 19th century that several inventors, including Heinrich Hertz, Guglielmo Marconi, and Nikola Tesla, began experimenting with wireless communication. Marconi became the first person to send and receive radio signals across the Atlantic Ocean, marking the birth of modern radio communication.

Invention of the Radio

The invention of the radio is attributed to several individuals, but the most notable was Marconi. He developed the first practical wireless telegraphy system, which he demonstrated in 1895. The system used a spark transmitter and a coherer receiver to transmit Morse code messages over a distance of several miles. Marconi’s invention revolutionized communication, making it possible to transmit information wirelessly for the first time.

Early Radio Broadcasting

The first radio broadcast is often credited to KDKA in Pittsburgh, Pennsylvania, which aired the presidential election results on November 2, 1920. However, prior to this, there were several experimental broadcasts by amateur radio operators, including the first voice transmission by Reginald Fessenden on Christmas Eve in 1906. Radio broadcasting quickly became popular, and by the mid-1920s, there were hundreds of radio stations across the United States.

The Golden Age of Radio

The 1930s and 1940s are known as the “Golden Age” of radio, a time when radio was the primary source of entertainment and news for millions of people. During this period, radio programs ranged from dramas and comedies to music and variety shows. Some of the most popular shows included “The Lone Ranger,” “The Shadow,” and “The Jack Benny Program.” Radio also played a significant role in shaping public opinion, with broadcasts by Franklin D. Roosevelt and his fireside chats.

The Impact of Radio during World War II

During World War II, radio played a critical role in relaying information to the public and the military. It was used for propaganda, news reports, and morale-boosting broadcasts. Radio operators were also instrumental in intercepting enemy transmissions, providing valuable intelligence to the Allies. The war also spurred technological advancements in radio, including the development of radar and the use of radio navigation.

The Rise of FM Radio

In the 1950s and 1960s, radio technology continued to evolve. The introduction of FM radio, which offered superior sound quality, helped to usher in a new era of radio broadcasting. AM radio remained popular for news and talk shows, while FM radio became the primary medium for music. Some of the most popular FM radio stations of the era included WNEW-FM in New York and KSAN-FM in San Francisco.

The Introduction of Satellite and Internet Radio

In the 1990s, satellite radio was introduced, offering listeners a wider range of programming options and better sound quality. Satellite radio services like SiriusXM quickly gained popularity, providing access to hundreds of commercial-free music channels and exclusive programming. The rise of the internet also led to the introduction of internet radio, which allowed listeners to stream radio stations from around the world using their computers or mobile devices.

The Evolution of Radio Advertising

Radio advertising has been an essential part of the medium since its inception. In the early days of radio, advertising was primarily done through sponsorships of individual programs. Today, radio advertising has evolved to include commercials, endorsements, and product placement. The rise of internet radio has also led to new opportunities for advertising, including targeted ads based on listener demographics.

The Future of Radio

Despite the rise of new technologies, radio remains a popular medium for entertainment and information. In recent years, podcasting has become increasingly popular, offering listeners a new way to consume audio content. As technology continues to evolve, it is likely that the future of radio will involve new forms of content delivery, including virtual and augmented reality.

Conclusion

Radio has come a long way since its inception, from the early experiments with wireless communication to modern satellite and internet radio. It has played a significant role in shaping our culture and the way we consume news and entertainment. While the medium has faced many challenges over the years, it remains an essential part of our daily lives. As we look to the future, it will be exciting to see how radio continues to evolve and adapt to new technologies and changing consumer preferences.

There is, however, a hobby of a very special kind. It allows you to combine the excitement of the hunter and the passion of the collector, makes you engage in design, requires the ability to speak foreign languages, prompts to get acquainted with the geography and radio engineering. You’ve guessed, of course, that we’re talking about shortwave amateur radio.

Amateur radio is a communication service used for purposes of self-improvement, mutual communication and technical research by radio amateurs, i.e. persons who are duly authorized to do so and who are engaged in radio technology solely for personal interest and without material gain.

According to the latest figures, the total number of shortwave amateurs in the world will soon reach several million. The youngest members of this army are less than ten years old and the oldest are over seventy. Shortwave radio enthusiasts include people of technology and art, servicemen and housewives, schoolchildren and students, teachers and politicians, workers and entrepreneurs. At various times, King Hussein of Jordan, the King of Spain and the president of Argentina, and people of lesser status, such as Joe Walsh – member of the band “EAGLES”, the co-author of the famous hit “Hotel California” were into radio amateurism.

But don’t think that shortwave is only for men. Every year, shortwave radio is finding more and more not only fans, but female fans as well. Approximately every 50th call sign belongs to a woman – an amateur radio operator, and this ratio is gradually leveling off.

What is it about amateur radio that attracts people from so many different professions and occupations?

First, the unpredictability of our hobby, including the radio station, I sometimes do not suspect who my next correspondent will be: my neighbor in the city or the expedition members to Easter Island. Of course, modern means of communication, including the Internet, have greatly simplified the task of communicating with a distant station, but the process of its implementation has not become less interesting.

Secondly, our hobby is very versatile. You can work with distant or rare stations, participate in competitions, fulfill the conditions of various diplomas, engage in the design of amateur equipment, use digital forms of radio communication, or just every evening to turn on the radio station in order to meet with old friends, even from the neighboring city or to make new friends.

Yes, that’s right, today the task of exchanging information is simplified to the limit – one click, and all that is needed is transmitted, and the end user does not need any additional knowledge and skills. Radio communications have been seriously displaced by new technologies, but…

And here comes the proverbial “BUT”. Unfortunately, the reliability of the transmission of information by the most common methods today is far from perfect. How often have you heard the answer when dialing the required number from your cell phone: “The subscriber is unavailable or out of the coverage area”, although you know for sure that your subscriber is just a couple of streets away from you, simply for some reason he has no connection with the base station of mobile communication or at the latter there was a failure.

And now imagine a force majeure case – a serious failure of some base station of the cellular system – how many people will be “out of range”? There’s no need to talk about wired communications (telephone and Internet). It is enough to break your line somewhere in a well or switchboard a couple of kilometers away, and you will be out of touch for a long time because you will not be able to fix it yourself.

And now for the most extreme case – a natural disaster or catastrophe. Lack of communication in these situations can lead to simply unpredictable results. And it is in such situations, radio communication was, is and will remain the most reliable, mobile and rapid means of communication.

After all, it may take an experienced radio amateur a little more than 20-30 minutes to set up a station right in the “open field”. Enough ordinary amateur transceiver (the parameters of modern amateur transceivers are not inferior to professional equipment, if not surpass it), a small fiberglass fishing rod, a couple of pieces of wire, coaxial cable to connect such “antenna” and car battery 12V. In this range of communication between amateur radio stations, even with this rudimentary equipment will calmly keep within 1500-2000 kilometers.

However, there is no point in getting upset and panicking, because there is nothing to worry about. Unfortunately, from the point of view of the average man, our hobby is poorly understood, and poorly understood things always inspire “suspicion”. So we are going to dispel several “myths” about radio amateurs.

Myth One.

Their big antennas pick up all the radio waves, our little TV antennas get nothing, and our TV sets don’t show soap operas very well.

The myth is based on ignorance of the laws of electromagnetic wave propagation. Their intensity is the same at all points in space within a single roof of a house. But the efficiency of each antenna is different, and the bigger your antenna, the greater its efficiency and the greater the signal level it can supply to the input of the TV receiver. And when someone offers you to buy an antenna the size of a shoebox, claiming that it, they say, “all-wave” and “active” and even designed with advanced technology, you know, you are not being told the truth and effective reception of TV or broadcast stations you will be hard to achieve.

Myth two.

Radio amateurs – these are such retarded retrogrades, “soldering at the knees. It’s the 21st century, there are computers and cell phones around, and they suffer, passing Morse code.
The myth is based on the idea of radio amateurs 50-60 years of the last century. First, modern technology is not only used by radio amateurs, but developed by them. Digital signal processing in amateur equipment is already a common thing, the computer not only can be used to transmit any digital data, but can also control the transmitter. The time of “soldering at the knees” is long gone! Today’s amateur radio designs are equipped with both digital controls and automation, and even remote control via the Internet.

Myth three.

They talk on the air all day about nothing.
This myth is a consequence of ignorance of the specifics of amateur communications. A real radio amateur listens on the air most of the time, that is, works on reception. For it is possible to chat constantly only with well acquainted people, and he has to conduct radio communications with actually strangers, so that long lengthy conversations in the radio amateur environment is very rare. In addition, if the radio amateur has large antennas, he is most likely interested in long distance communications, that is, not with Europe, but rather with an island in the Pacific or North America.

Myth Fourth.

The main purpose of the amateur radio operator is to interfere with everyone around him and to eavesdrop on the work of the police or other official communication channels.
A myth born of the journalistic fraternity, based on the substitution of concepts. An amateur radio enthusiast is a person who loves the radio, but not the information that the radio transmits. The real radio amateur will never eavesdrop on the work of service stations, because it is of no interest to him (situations of natural disasters and other force majeure circumstances are not taken now).

Putting interference on intercom frequencies (or in general work to transmit outside the limits of frequencies assigned to this station), puts any owner of a transmitting device in the category of RADIOHULIGAN. Therefore, if the media reports that some amateur radio operators interfere with some services, they are actually RADIOHULIGANS who violate the law in force.

Myth Five.

Radio amateurs are “sick” people! Is it reasonable to stay up all night (build big antennas, spend so much effort and money, etc.) just to talk for 20 seconds with a stranger, etc.
This is the traditional statement of those who have never had any hobby. We always give ourselves to the hobby we love without reserve. We spend energy and money on any achievement in the hobby we love – an extra stamp in the collection, an extra decibel in the volume of the car audio, an extra kilometer of route, an extra unique photo, etc. Similarly, radio amateurs spend energy and money on their antennas and equipment, getting in return for the pleasure of making a radio call, not even of transmitting information!

There are a lot of “strange” activities in the world, from fishing and hunting to mountain climbing, snowboarding and other outdoor activities, which often cause a lot of trouble for emergency crews. So if you have a favorite hobby, try to look at it from another angle, and you will see all its “strangeness. If there is no hobby, believe me, the adrenaline in our blood from making difficult or unique radio communications is no less than from a portion of good alcohol, not to mention winning competitions or other achievements in amateur communications.
