Portal:Radio
The Radio Portal Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 3,000 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is widely used in modern technology, in radio communication, 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 receiver accepts 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.

Michael Alan Weiner (born March 31, 1942), known by his professional name Michael Savage, is an American right-wing author, political commentator, activist, and former radio host. Savage is best known as the host of The Savage Nation, a nationally syndicated talk show that aired on Talk Radio Network across the United States until 2021, and in 2009 was the second most listened-to radio talk show in the country with an audience of over 20 million listeners on 400 stations across the United States. From October 23, 2012, to January 1, 2021, Michael Savage had been syndicated by Cumulus Media and Westwood One. He holds master's degrees from the University of Hawaii in medical botany and medical anthropology, and a Ph.D. from the University of California, Berkeley in nutritional ethnomedicine. As Michael Weiner, he has written books on nutrition, herbal medicine, and homeopathy; as Michael Savage, he has written several political books that have reached The New York Times Best Seller list. Savage has summarized his political philosophy in three words: borders, language, and culture. He has characterized his views as conservative nationalism, while critics have characterized them as "fostering extremism." He supports the English-only movement and argues that liberalism and progressivism are degrading American culture. Although his radio delivery is mainly characterized as politically themed, he also often covers topics such as medicine, nutrition, music, literature, history, theology, philosophy, sports, business, economics, and culture, and tells personal anecdotes.
