A VOR station broadcasts a VHF radio signal including the identifier, voice, and navigation signal. The identifier is in Morse Code. The voice will have information from the station. The navigation signal allows the equipment to find a magnetic bearing from the station to the aircraft. VOR stations in areas of magnetic unreliability are oriented to True North. A line of position is called the "radial" from the VOR. The crossing of two radials from different VOR stations provides the position of the aircraft. VOR signals have a range of about 200 miles.
