Call Sign
In broadcasting and radio communications , a CALL SIGN (also known as a CALL NAME or CALL LETTERS—and historically as a CALL SIGNAL—or abbreviated as a CALL) is a unique designation for a transmitter station . In North America, they are used for all FCC licensed transmitters. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations , there needed to be a way to address each one when sending a telegram . In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations aboard ships at sea

Broadcasting
BROADCASTING is the distribution of audio or video content or other messages to a dispersed audience via any electronic mass communications medium , but typically one using the electromagnetic spectrum (radio waves ), in a one-to-many model. Broadcasting began with AM radio , which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers . Before this, all forms of electronic communication (early radio , telephone , and telegraph ) were one-to-one, with the message intended for a single recipient. The term _broadcasting_, borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners

Amateur Radio
AMATEUR RADIO (also called HAM RADIO) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport , contesting , and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting , public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.)

ITU Prefix
The International Telecommunication Union
International Telecommunication Union
(ITU) allocates call sign prefixes for radio and television stations of all types. They also form the basis for, but do not exactly match, aircraft registration identifiers. These prefixes are agreed upon internationally, and are a form of country code . A call sign can be any number of letters and numerals but each country must only use call signs that begin with the characters allocated for use in that country. A few countries do not fully comply with these rules. Australian broadcast stations officially have—but do not use—the VL prefix, and Canada
