Broadcast Call Sign
Broadcast call signs are call signs assigned as unique identifiers to radio stations and television stations. While broadcast radio stations will often brand themselves with plain-text names, identities such as " cool FM", " rock 105" or "the ABC network" are not globally unique. Another station in another city or country may (and often will) have a similar brand, and the name of a broadcast station for legal purposes is normally its internationally recognised ITU call sign. Some common conventions are followed around the world. Excluding those used in amateur radio, call signs are traditionally only used in the Americas and few countries such as Australia, Japan, the Philippines, South Korea and Taiwan. North America Broadcast stations in North America generally use callsigns in the international series. International shortwave The US government-operated international broadcaster the Voice of America no longer uses callsigns assigned to it; however, Radio Canada Internation ...

In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; Radio industry, radio companies initially assigned two-letter identifiers to coast radio station, coastal stations and marine radio, stations on board ships at s ...

AM Radio
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. 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 radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received much of the programming previously carried by radio. Later, AM radio's audiences declined greatly due to competition from FM (FM broadcasting, frequency modulation) radio, Digital audio broadcasting, Digital Audio Broadcasting (DAB), satellite radio, HD Radio, HD (digital) radio, In ...

The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. Depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Translators In its simplest form, a broadcast transl ...
