Orlando Executive Airports VOR.

A VOR (Acronym: VHF[Very high frequency] Omnidirectional Range) is a short range radio station that enables aircraft with a receiver to pick up radio signals from that station and track it to/from via a radial.

VOR frequencies range from 108.00 to 117.95 MHz and are useful up to 200 nm away as long as the receiver is in line of sight of the station.
