An AM radio station is a type of broadcasting service that transmits audio signals using amplitude modulation. This method varies the strength of the signal to convey sound, allowing listeners to receive news, music, and talk shows. AM radio is known for its long-range capabilities, making it suitable for reaching rural and remote areas. Typically, AM stations operate on specific frequencies measured in kilohertz (kHz). They are often part of a larger network of radio stations, providing local content while also connecting listeners to national programming. Many AM stations also offer online streaming, expanding their audience beyond traditional radio waves.
