Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the high frequency band (HF), which extends from 3 to 30 MHz ; above the medium frequency band (MF), to the bottom of the VHF band.
BBC Radio 4 is a British national radio station owned and operated by the BBC. The station replaced the BBC Home Service on 30 September 1967 and broadcasts a wide variety of spoken-word programmes from the BBC's headquarters at Broadcasting House, London. Since 2019, the station controller has been Mohit Bakaya. He replaced Gwyneth Williams, who had been the station controller since 2010.
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions and quality of radio receiver used. Improved signal propagation at night allows the reception of much longer distance signals. This can cause increased interference because on most channels multiple transmitters operate simultaneously worldwide. In addition, amplitude modulation (AM) is often more prone to interference by various electronic devices, especially power supplies and computers. Strong transmitters cover larger areas than on the FM broadcast band but require more energy and longer antennas. Digital modes are possible but have not reached momentum yet.
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 transmissions, but also on the longwave and shortwave radio bands.
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. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM, FM radio stations transmit in FM, which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB, HD radio, DRM. Television broadcasting is a separate service that also uses radio frequencies to broadcast television (video) signals.
A time signal is a visible, audible, mechanical, or electronic signal used as a reference to determine the time of day.
Radio Televisión Martí is an American state-run radio and television international broadcaster based in Miami, Florida, financed by the federal government of the United States through the U.S. Agency for Global Media.

Radio Havana Cuba is the official government-run international broadcasting station of Cuba. It can be heard in many parts of the world including the United States on shortwave frequencies. Radio Havana, along with Radio Rebelde, Cubavision Television and other Cuban radio and television broadcasts to North, Central and South America via free-to-air programming from the Hispasat 30W-6 satellite over the Atlantic Ocean and via Internet streaming.
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.
Radio jamming is the deliberate blocking of or interference with wireless communications. In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio.

Radio 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 are received by another antenna connected to a radio receiver. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications.
The mass media in Cuba consist of several different types: television, radio, newspapers, and internet. The Cuban media are tightly controlled by the Cuban government led by the Communist Party of Cuba (PCC) in the past five decades. The PCC strictly censors news, information and commentary, and restricts dissemination of foreign publications to tourist hotels. Journalists must operate within the confines of laws against anti-government propaganda and the insulting of officials, which carry penalties of up to three years in prison. Private ownership of broadcast media is prohibited, and the government owns all mainstream media outlets.
Beaker Street with Clyde Clifford was the first underground music program broadcast regularly on a commercial AM radio station in the central US. The station's signal carried far and wide. In early 1967 Beaker Street was a staple for adherents to the burgeoning underground communities in the upper Mid-West especially in Des Moines, Iowa, where it was the only access to Dr. Demento and Firesign Theatre. Beaker Street began on Little Rock, Arkansas 50,000 watt AM radio station KAAY late in 1966 and ran through 1972. The show's original announcer, Clyde Clifford, moved to FM in 1974 as the rise in popularity of FM radio began to impact the operations of many AM stations. Beaker Street pre-dated the FM radio boom of the mid-1970s and foretold the rise of album-oriented Rock and Classic rock formats.
