AM broadcasting, or Amplitude Modulation broadcasting, is a technique used to transmit audio signals via radio waves by varying the amplitude of the carrier wave. It operates primarily in the medium wave (MW) band, typically between 530 to 1700 kHz, and is characterized by its long-range capabilities, especially at night when atmospheric conditions favor signal propagation. The standard for AM broadcasting is defined by the International Telecommunication Union (ITU) and various national regulatory bodies, which ensure compatibility and interference management among stations. Despite being more susceptible to noise and interference than FM broadcasting, AM remains popular for talk radio, news, and sports coverage.
