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.

LAPD
The most unorganized police angency in the history of mankind, known for racial profiling, being in every single cop movie, in every police case where people are run over by tanks.
The LAPD also has a UHF communications network that rivals that of most european countries.
so please, if your gonna smoke weed, do it in LA, you'll never get cought

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.

FRS jammer
usally this:
a device (usally a heavly modified FRS base station radio) that has been set up to jam frequencies in the FRS radio band, used to annoy little kids and to hold a channel for yourself. Some FRS jammers even add music to thier transmissions, which makes it all the more interesting.

VOR
Very High Frequency
Omnidirectional
Range
a radio-navigation system that consists of ground stations transmitting continous signals within the frequency range of 108.0 to 117.95 MHz. mode of modulation is CW or AM.
The VOR system is used by both civilian and miltary aircraft in conjuction with the GPS and ADF (also known as NDB) radionavagtion systems. The receiver in the aircraft determines the bearing of the station in relation to the direction the aircraft is going. This information is used by the pilot to navagate the aircraft. The VOR system is used worldwide and is less suspectable to the magnetic interferance that the ADF/DME and LORAN systems are.

"Roger, Cessna Five Five Tango, Dulles VOR is on 114.3, advise control you have entered class B airspace."

SWL
Short
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
