- 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 vs FM - Difference and Comparison | Diffen
AM (or Amplitude Modulation) and FM (or Frequency Modulation) are ways of broadcasting radio signals Both transmit the information in the form of electromagnetic waves
- 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, 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
- AM Vs FM: Whats The Difference Between AM And FM? - Science ABC
Amplitude Modulation, commonly abbreviated as AM, is a common method of broadcasting radio signals This method dates back to the 1870s, i e the time when we first discovered that information in the form of audio production can be broadcast over long distances through radio waves
- AM (Amplitude Modulation) - Definition Detailed Explanation - Radio . . .
While FM has become the dominant modulation technique for music and high-fidelity audio broadcasting, AM still has its place in modern radio broadcasting AM is often used for talk radio, news broadcasts, and sports programming, where the focus is on spoken content rather than music

What is AM broadcasting? AM broadcasting is radio broadcasting using amplitude modulation transmissions
