Digital Audio BroadcastingDigital radio standardOfficial DAB+ logoOfficial DAB logo (1990s–2018)A Pure DAB receiverDigital Audio Broadcasting (DAB) is a digital radiostandard for broadcastingdigital audio radio services in many countries around the world, defined, supported, marketed and promoted by the WorldDAB organization.Radio networkA radio network is a system that distributes radio signals to multiple receivers or enables two-way communication between stations and mobile units.
FM broadcastingFM broadcasting is a radio broadcasting method that uses frequency modulation (FM) transmissions. In November 1919, Hans Idzerda began broadcasts, using narrow-band FM, over station PCGG, located at The Hague in the Netherlands. However, most early broadcasting stations instead employed Amplitude Modulation (AM) transmissions. In 1933, American engineer Edwin Armstrong began development of wide-band FM.
Amplitude modulationAmplitude modulation (AM) is a signal modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the instantaneous amplitude of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its phase, as in phase modulation.
Talk showA talk show or chat show is a television programming, radio programming and podcast genre structured around the act of spontaneous conversation. A talk show is distinguished from other television programs by certain common attributes; in a talk show, one person (or group of people or guests) discusses various topics put forth by a talk show host.
Push-to-talkPush-to-talk (PTT), also known as press-to-transmit, is a method of having conversations or talking on half-duplex communication lines, including two-way radio, using a momentary button to switch from voice reception mode to transmit mode. HistoryFor example, an air traffic controller usually supervises several aircraft and talks on one radio frequency to all of them.
MusicMusic is the arrangement of sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music is defined by a small number of specific elements, there is no consensus as to what these necessary elements are.

RadioRadio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication.
AdvertisingAdvertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to present a product or service in terms of utility, advantages, and qualities of interest to consumers. It is typically used to promote a specific good or service, but there is a wide range of uses, a traditional form being commercial advertisement.Text displayA text display is an electronic alphanumericdisplay device that is mainly or only capable of showing text, or extremely limited graphic characters. This includes electromechanicalsplit-flap displays, vane displays, and flip-disc displays; all-electronic liquid-crystal displays, incandescent eggcrate displays, LED displays, and vacuum fluorescent displays; and even electric nixie tubes. There are several ways to form text for display.EpisodeAn episode is any independently presented unit within a larger continuous work of dramatic, comedic, or documentary narrative, forming part of a series in media such as radio, television, film, or streaming media. Typically, each episode is published or delivered to the public in sequential, serial installments across weeks, months, or years (known as serialization for written narratives).*As an Amazon Associate I earn from qualifying purchases.
