> VOR= "VHF Omni Range"
> These are (were) the things that look like gigantic bowling pins, 
> generally located near airfields or at intersections of US Airways.  
> They broadcast a periodic omnidirectional pulse and a rotating (azimuth) 
> beam signal which is synchronous with the omnidirectional pulse at 0 
> degrees.  An aircraft navigation receiver can determine its compass 
> bearing from the VOR by measuring the time lag between the 
> omnidirectional signal and the rotating beam signal.
> There were also ranging systems in some of these things (DME), which 
> required an aircraft transponder.

> With the advent of GPS navigation, these systems are not long for this 
> world.

> Your meter must be a piece of test equipment for use by those who
