Automatic Direction Finding System
a navagation system used by aircraft and sea-going ships. It consists of one or more ground stations that transmit a signal in the 225 to 500 kHz (.225 to .500 MHz) range. Because of the low-frequnecy of these signals, their range is very good and not limited by the line-of-sight range of the VOR system. The recevier in the airplane/boat uses a loop antenna to "home-in" on the station. There is also a long-wire receiving antenna installed on many aircraft. Most ADF receivers can also recieve the AM broadcast band (530 to 1710 kHz) so pilots can also home in on powerful broadcast stations.
ADF signals should not be used in thunderstorms because the high amount of electro-magnetic interferance that lightening causes.
Many pilots can't even use the ADF system, which is a shame, becuase of better systems such as VOR and the GPS systems.
"In most of the third world, the ADF navigation system is the only way to go"

sent to drain
Secret destroyers, hold you up to the flames
And what do I get, for my pain
Betrayed desires, and a piece of the game
Even though I know-I suppose I'll show
All my cool and cold-like old job
Despite all my rage I am still just a rat in a cage
Then someone will say what is lost can never be saved
Despite all my rage I am still just a rat in a cage
Now I'm naked, nothing but an animal
But can you fake it, for just one more show
And what do you want, I want to change
And what have you got
When you feel the same
Even though I know-I suppose I'll show
All my cool and cold-like old job
Despite all my rage I am still just a rat in a cage
Then someone will say what is lost can never be saved
Despite all my rage I am still just a rat in a cage
Tell me I'm the only one
Tell me there's no other one
Jesus was the only son
Tell me I'm the chosen one
Jesus was the only son for you
Despite all my rage I am still just a rat in a cage
And I still believe that I cannot be saved

If it's got an antenna attached to it, the NSA is listening

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.
