Radio formatA radio format, programming format (not to be confused with broadcast programming), or specialist station (British English) describes the overall content broadcast on a radio station. The radio format emerged mainly in the United States in the 1950s, at a time when radio was compelled to develop new and exclusive ways to programming by competition with television. The formula has since spread as a reference for commercial radio programming worldwide.

Alternative rockMusic genreAlternative rock (also known as alternative music, alt-rock or simply alternative) is a category of rock music that evolved from the independent music underground of the 1970s. Alternative rock acts achieved mainstream success in the 1990s with the likes of the grunge subgenre in the United States, and the Britpop and shoegaze subgenres in the United Kingdom and Ireland.Digital subchannelIn broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or televisionstation on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting".Radio masts and towersRadio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.

TransmitterIn electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequencyalternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves.
