Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardizes several types of information transmitted, including time , station identification and program information.
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong , wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio . [ 1 ]
An American FM radio transmitter in Buffalo, NY at WEDG. Edwin Howard Armstrong (1890–1954) was an American electrical engineer who invented wideband frequency modulation (FM) radio. [12] He patented the regenerative circuit in 1914, the superheterodyne receiver in 1918 and the super-regenerative circuit in 1922. [13]

Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
Also AM radio or AM. Used interchangeably with kilohertz (kHz) and medium wave. A modulation technique used in electronic communication where the amplitude (signal strength) of the wave is varied in proportion to that of the message signal. Developed in the early 1900s, this technique is most commonly used for transmitting an audio signal via a radio wave measured in kilohertz (kHz). See AM ...

16-line message format, or Basic Message Format, is the standard military radiogram format (in NATO allied nations) for the manner in which a paper message form is transcribed through voice, Morse code, or TTY transmission formats.
