AM radio, or Amplitude Modulation radio, is a type of broadcasting that transmits audio signals by varying the amplitude of the radio waves. This method allows for the transmission of voice and music over long distances, making it popular for news and talk radio stations. AM radio operates in the medium frequency (MF) band, typically between 530 and 1700 kHz. AM radio signals can travel far, especially at night when atmospheric conditions improve reception. However, they are more susceptible to interference from electrical devices and natural phenomena. Despite the rise of digital and FM radio, AM radio remains a vital source of information and entertainment in many communities.
