(radio slang)
An amplifier used after the transceiver output. So named for its purity of amplification. Linear, in the mathematical sense, means that what comes out is directly proportional to what goes in. As far as linear amps go, if you double the input, the output is doubled and so on. This does not generate any additional frequency byproducts. If the amp is nonlinear, sums, differences and all combinations of those are generated also.

1) A form of wireless communications in which the output of the transmitter takes the form of dissipating electromagnetic radiation which spreads outward from the antenna through free space. The signal strength drops off as the square of the distance from the source of radiation. Distant radio receivers have to be very sensitive to detect signals that can measure only a few microvolts per meter in strength.
2) A communications device allowing the wireless transmission through space of audible signals encoded in electromagnetic waves in the approximate frequency range from 10 kilohertz to 300,000 megahertz.
3) (maratime definition) An instrument that uses electromagnetic waves to communicate with other vessels. VHF radios are common for marine use, but are limited in range. HF-SSB (single sideband) radios have longer ranges.
4) an electronic receiver that detects and demodulates and amplifies transmitted signals
5) Radio is a system for the distribution of advertisement, chiefly brand advertisement for package-goods, and advertisement for recorded music sold by BigCos. To describe radio as a system for the diffusion of news, or of music, or as a technology, would be not only inaccurate but actually misleading. Radio is a creature of the advertising business, as its child, TV. television
6) Transmit messages via radio waves, usally on a set wavelength, or frequency.

Irregular scattered patches of relatively dense ionization that develop seasonally within the E region and that reflect and scatter frequencies up to 150 MHz. Note 1: The sporadic E is a regular daytime occurrence over the equatorial regions and is common in the temperate latitudes in late spring, early summer and, to a lesser degree, in early winter. Note 2: At high, i.e., polar, latitudes, sporadic E can accompany auroras and associated disturbed magnetic conditions. Note 3: The sporadic E can sometimes support reflections for distances up to 1000 miles or more at frequencies up to 150 MHz

An organization formed at Fairfax High School. The Future Hobos of America (FHA) really doesn't do anything, except form more FHA groups at other schools and sit around doing nothing.
