Radio continues to have an impressive audience despite the competition from all fronts. In America, according to Nielsen, over two hundred and seventy two million people (6+) listen to the radio every week. Therefore, it remains to be the top reach medium that touches more individuals than any other device. Moreover, the discovery of radio waves was among the most significant findings in communication. Without radio waves, there would have been a different technique to transmit radio broadcasts, cell phone service, television broadcasts, and wireless internet access. Find below more exciting 50 facts about radio.
1. Clerk Maxwell was the first to foresee that radio waves existed. His theory is known as Maxwell’s equations, and it described light and radio waves as electromagnetic waves traveling through space. Other types of electromagnetic waves include Bluetooth, radar, x-rays, infrared, ultraviolet, and microwaves.
2. Heinrich Hertz demonstrated radio waves in his lab in 1887. The unit of frequency of a radio wave — one cycle per second — is named the hertz, in honor of Heinrich Hertz. Radio is broadcasted in different frequencies, including the FM radio waves that range between 88 MHz and 108 MHz (FM stands for frequency modulation, which produces a wave of constant amplitude but varying frequency.) AM radio waves posted between 550 kHz and 1600 kHz.
3. The most powerful radio station ever was WLW (station licensed to Cincinnati, Ohio.) which broadcasted at 700KHz, and at some point, in the 1930s, the radio wave was 500Kw radiated power. Those in the vicinity of the transmitter could hear the audio in their pans, pots, and mattresses.
4. Guglielmo Marconi was able to send and receive his first radio signal in Italy in 1895, and in 1899 he sent a wireless signal transversely to the English Channel. In 1902 he received a letter ‘S’ telegraphed from England marking the first transatlantic radiotelegraph message.
5. In 1900, the Canadian inventor Reginald Fessenden managed to transmit the world’s first voice message. In 1906, on Christmas eve, he made the radio broadcast.
6. In the 1980s, people were able to download video games from a radio broadcast. They would record the sounds onto a cassette tape, and then they could play later on their computers.
7. A thirteen-year-old called out the Eastern State Penitentiary for having the wrong radio on display during Al Capone’s cell recreation. There was no radio until 1942, and Capone was imprisoned between 1929 and 1930, thus resulting in the museum replacing it and giving the teen inaccurate radio.
8. The first public radio broadcasts were done on top of the Eiffel tower by radio scientists. Lee de Forest, together with his peers, is viewed as the father of radio broadcasting. Being an opportunist, he took a break on his honeymoon in 1908 and climbed France’s most famous landmark. He broadcasted a selection of music to the Parisian suburbs and became the first radio DJ.
9. The Eiffel Tower was meant to be brought down after twenty years. However, it survived because the military began to use it as a radio tower to intercept crucial military transmissions during World War I.
10. UVB-76 is a secretive Russian radio signal that has been continuously transmitting since 1982. Although no one knows who makes the signal, it is located near Moscow and makes a buzzing sound twenty-five times a minute. The station was originally identified as UVB-76 and then MDZhB but is commonly known as The Buzzer.
11. The 1946 radio show ‘Adventure of Superman’ revealed the secret rituals and codes of the KKK, making it a laughing stock. As a result, the Klan recruitment was dried up almost overnight.
12. The first incident of telephone hold music was a mistake caused by a loose wire touching a metal girder at a factory. It turned the entire building into a mega radio antenna that would play the music from a next-door radio station when people were on hold.
13. The radio stations located on the East of River Mississippi use ‘W’ as the first letter in the call signs, and those to the West use ‘K’ for their call signs. An example of an East radio station call sign is WIHB.
14. A considerable number of birds are killed by radio antennas each year. However, if the static red light is changed to a blinking light, it can reduce the death toll by up to seventy percent. In the United States, the US Fish and Wildlife Service estimates that between 4 and 50 million birds are killed each year by tower kill.
15. In World War II, they censored weather reports to avert the enemy submarines from knowing the conditions. At that time, a football match in Chicago was covered in fog, but the radio announcer never used the name ‘fog’ or mentioned the weather.
16. David Sarnoff, who is the founder of RCA (Radio Corporation of America), fought very hard to avert FM radio from succeeding. Eventually, Edwin Howard Armstrong, the inventor of the FM radio, committed suicide due to emotional and financial distress that he suffered from RCA lawsuits.
17. It is believed that radio waves will continue to travel forever unless something absorbs them. If that is the case, and if there are more life forms in other parts of the universe, then other planets may have heard the radio waves.
18. In 1932, experts revealed that astronomical objects emit radio waves. A system has been established that makes it possible to produce pictures from radio waves. Thus, astronomers are using radio telescopes to study radio waves emitted from specks of dust, planets, gas clouds, stars, comets, and other galaxies.
19. A text message sent from a cell phone to another phone is a radio wave. The text leaves the sender’s phone and is sent to a tower that transmits the lock to the message’s recipient. They are all unique radio waves being sent, enabling them to reach the right person.
20. When the cowboy and actor Slim Pickens joined the military during World War II, he stated that his profession was ‘rodeo.’ The recruiter heard ‘radio.’ Slim spent his entire wartime as a radio operator.
21. An obsessed fan of Muppet once took a radio manager hostage claiming that he had a bomb. He demanded that the rainbow connection song be played nonstop for the next twelve hours on the radio.
22. Shortly after the 9/11 terrorist attacks, all radio stations received a memo with a list of songs that they viewed to be lyrically inappropriate. The list contained one hundred and sixty-five suggested songs, with one of them reading ‘Every Rage Against Machine Song.’
23. Colombia’s armed forces commissioned a pop song with a Morse code message to the kidnapped military personnel stating, ‘nineteen people rescued, you are next, do not lose hope. The kidnappers used to let their captives listen to the radio.
