SWL

Wave
Listener

in other words, a radio operator who listens to short wave radio transmissions and spends all of his time hunched in front of a 5000 dollar radio, is usally a cracker and a loser

FM

FREQUENCY MODULATION

radio modulation techique where information (usally voice or music) is added to the signal and changed by varying the freqeuncy of the transmitter. FM is the most commonly used modulation for radio signals techneque above 30 MHz.

the term "FM" is also used to refer to the broadcast band from 88.1 to 107.9 MHz, using that same modulation mode.

FM signals have less static because changes in frequency do not pick up interferance that AM-modulated signals do.

Future Hobos of America

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.

Many of the members of the FHA are republicans

ELT

Emergency Locator Transmitter. The ELT is a small radio transmitter that is installed in an aircraft and is designed to being transmitting upon impact (the crash) or it can be manually switched on. The ELT transmits a distincive signal on the international emergency frequencies of 121.5 MHz (VHF) and 243.0 MHz (UHF). This signal is picked up by ground stations, search and resuce aircraft (see Civil Air Patrol and Coast Guard, and satelites. Direction-finding equipment is then used to "home-in" on the signal and locate the downed aircraft.

GPS

Global Positioning System

Complex network of satellites that transmit signals to ground receviers in cars, boats, airplanes (see also VOR). The GPS receiver uses the signals from the satellites (which are over 15,000 miles away!) and uses them to find your location, anywhere in the world, with incredable accuracy.

Without GPS, countless losers who can't use a VOR would be lost"

Spybot - Search & Destroy

An excellent program which removes Spyware, Adware, daillers and many other malacious programs and files on your computer. It can also fix registry problems and remove usage tracks from your registry. It is a free download as are the update files (same with Ad-Aware, another great program).

I use both Ad-Aware and Spybot - Search & Destroy on my computer to remove spyware and other bad programs.
