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.

In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location. In radio navigation systems such as GPS and VOR, a mobile navigation instrument receives radio signals from navigational radio beacons whose position is known, and by precisely measuring the arrival time of the radio waves the receiver can calculate its position on Earth. In wireless radio remote control devices like drones, garage door openers, and keyless entry systems, radio signals transmitted from a controller device control the actions of a remote device.

The Quatermass Memoirs is a British radio drama-documentary, originally broadcast in 5 episodes on BBC Radio 3 in March 1996. Written by Nigel Kneale, it was born out of his Quatermass series of films and television serials, which had first been broadcast in the 1950s. The idea for the show appeared as BBC radio intended to create a season of programming looking back at the 1950s, and it was the final piece of writing Kneale completed relating to the character.

The show is centered on the character of Professor Bernard Quatermass who, albeit older than in the previous series, is "the same very concerned scientist" but worried about his previous decisions. Andrew Keir, who had played Quatermass in the 1967 film Quatermass and the Pit, was chosen to voice the character. Later, Nigel Kneale himself became dismissive of the serial, but critics gave the production relatively positive reviews. (Full article...)
