AM radio broadcasting, or Amplitude Modulation, is a method of transmitting audio signals over radio waves. It works by varying the strength (amplitude) of the radio signal to encode sound information, such as music or speech. AM radio is commonly used for talk shows, news, and music, and operates in the medium frequency (MF) band, typically between 530 and 1700 kHz. One of the key features of AM radio is its ability to cover long distances, especially at night when atmospheric conditions allow signals to travel further. However, AM broadcasts are more susceptible to interference from electrical devices and weather conditions compared to FM radio. Despite these limitations, AM radio remains a popular choice for many listeners due to its accessibility and wide reach.
