2. The History of AM Radios
The history of AM radios dates back to the early 20th century. In 1906, Reginald Fessenden made the first voice transmission over the airwaves, and by 1920, commercial radio broadcasting was underway. AM, or amplitude modulation, was the dominant technology used in radio broadcasting until FM, or frequency modulation, became more prevalent in the 1960s. However, even today, many stations still use AM technology for their broadcasts.
3. How AM Radios Work
AM radios work by transmitting radio waves through the air that are then picked up by a receiver. The radio waves are modulated, or changed, to carry the audio signal. The amplitude, or strength, of the radio waves is changed to match the audio signal, creating the distinctive sound of AM radio. The radio waves are then picked up by the antenna on the receiver and converted back into an audio signal, which is then played through the radio’s speakers.
