- AM broadcasting - Wikipedia
The earliest experimental AM transmissions began in the early 1900s However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters
- AM Broadcast Frequency Spectrum - dummies
The 535- to 1,705-kHz frequency band, which broadcast AM occupies, is classified as a medium frequency (MF) radio band Medium wave signals follow the curvature of the Earth, using ground wave propagation, but can also bounce off the ionosphere at night, resulting in skywave propagation
- AM Radio: A Complete Overview (2025) - Radio Active Media
AM radio, also known as Amplitude Modulation, is a type of radio broadcasting that uses amplitude modulation to transmit audio signals AM radio signals are transmitted through the airwaves and can travel long distances, making it a popular choice for radio broadcasters
- AM Radio - Federal Communications Commission
In many countries, AM radio stations are known as "mediumwave" stations They are also sometimes referred to as "standard broadcast stations" because AM was the first form used to transmit broadcast radio signals to the public
