What frequencies does VOR operate on?

The VOR (VHF Omnidirectional Range) navigational system operates specifically within the frequency range of 108.0 to 117.95 MHz, and it deliberately excludes odd tenths (e.g., frequencies like 108.1, 108.3, etc.). This design helps to reduce interference and ensures that there are standard frequencies available for various navigational aids.

By excluding odd tenths, the VOR system provides a clear and defined set of frequencies that can be used by aircraft for consistent navigation without the confusion of overlapping frequencies. The specific band allocated for VOR helps in delivering the required precision for aircraft navigation, distinguishing it from other systems that might operate in the same radio bands. Overall, this careful frequency allocation contributes significantly to flight safety by providing reliable navigation signals to pilots.
