Then, with just a little math you'll know your bearing from the station. If you know how fast the rotating light is moving, it's a simple matter to start a timer when the omnidirectional light flashes, just as the rotating light passes north, and then note the time when you see the rotating beam aim at your position. The other light flashes-and can be seen in all directions (an omnidirectional light)-only when the rotating light exactly passes magnetic north. One light rotates at a constant rate around the tower but has a very narrow beam so that it can only be seen by the viewer just as the beam passes the viewer's position. You can get your mind around this concept by thinking of a tower with two lights on it. VORs work on the principle of the phase difference in two radio signals. Here's an article on how VORs work - tuning in a (Aircraft COMs are 118 to 137 MHz, so this chip saying it can pick up "aircraft conversation" is little bit off.) This might be a starting point for a DIY circuit
