Radio broadcasting is the broadcasting of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (radio). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. The encoding of a radio broadcast depends on whether it uses an analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB, HD radio, or DRM.
The FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world. In Europe and Africa and in Australia and New Zealand, it spans from 87.5 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz, and in Brazil, 76 to 108 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.9 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108 MHz band.

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. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio. FM radio stations use the very high frequency range of radio frequencies.

Manx Radio is the national commercial radio station for the Isle of Man. It began broadcasting on 29 June 1964, almost ten years before legal commercial radio was licensed in the United Kingdom. The Isle of Man, having its own government and laws, was not subject to the rules prohibiting commercial broadcasting in the UK. However, the Manx Government still had to apply to the UK's General Post Office for a frequency and for permission to broadcast. First requested in 1960, a licence was eventually granted in May 1964. It was allocated an FM frequency of 89.0 MHz and a comparatively low power of 50 watts. In October 1964, an additional frequency of 1594 kHz AM was allocated to the station to provide greater coverage, although again at a limited power of 50 watts. It broadcasts primarily in English with several hours per week of Manx language programming.
WFED is a 50,000-watt Class A radio station in the Washington, D.C. region. The station, branded as "Federal News Network", broadcasts a news/talk format focused on issues and news pertaining to members and staff of the United States government. Owned by Hubbard Broadcasting, the current WFED is the second in the Washington area to carry the Federal News Network format as WFED, as from 2004 until a transfer in 2008, this format and related call letters were used by a Silver Spring, Maryland station broadcasting on 1050 kHz.
CFML-FM is the campus radio station of the British Columbia Institute of Technology in Burnaby, British Columbia, Canada.
Apex radio stations was the name commonly given to a short-lived group of United States broadcasting stations, which were used to evaluate transmitting on frequencies that were much higher than the ones used by standard amplitude modulation (AM) and shortwave stations. Their name came from the tall height of their transmitter antennas, which were needed because coverage was primarily limited to local line-of-sight distances. These stations were assigned to what at the time were described as "ultra-high shortwave" frequencies, between roughly 25 and 44 MHz. They employed amplitude modulation (AM) transmissions, although in most cases using a wider bandwidth than standard broadcast band AM stations, in order to provide high fidelity sound with less static and distortion.
