The Radio Portal 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 to a receiver that is typically colocated with the transmitter. In radio navigation systems such as GPS and VOR, a mobile navigation instrument receives radio signals from multiple 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.

Selected article -Planet B is a science fiction drama series first broadcast on BBC Radio 7 on 2 March 2009 as part of BBC Radio's science fiction season between February and March 2009. Planet B is set in a virtual world called "Planet B" in which people play as life-size avatars. The first series follows John Armstrong who attempts to find his girlfriend Lioba Fielding who is dead in the real world but alive in Planet B. As he travels between various worlds he becomes entangled in an array of strange scenarios, teleporting from each adventure to the next with his companion Medley, a "rogue avatar" who has no human controller. All the while, John and Medley are being watched by a dog-like antivirus programme called Cerberus who, along with the Planet B Corporation, considers the rogues to be a computer virus that need to be wiped out. In the second season, Lioba is on the run from Planet B and travels the virtual world with computer games expert Kip Berenger after they are attacked by Cerberus. The series was created by Sam Hoyle, Jessica Dromgoole and Matthew Broughton with James Robinson. The first series ran for ten episodes and was BBC Radio 7's biggest ever commission for an original drama series. A second series of five episodes was broadcast from 29 November 2009 to 27 December. A third series of five episodes ran from 30 January through 27 February 2011. ( Full article...)General images -The following are images from various radio-related articles on Wikipedia.
