A non-directional beacon is the most basic type of radio beacon. The equipment on board of our aircraft will have to figure out where it is. Any (music) radio station is also a NDB.

It ''is'' possible to calculate the distance towards a NDB station. For that a pilot flies on a 90 degree angle opposite the station (one wing-tip pointing towards the station). The pilot measures the time it takes to fly a number of degrees on the compass.

In the Americas the NDB's operate 530 kHz to 1700 kHz with 10 kHz increments. The rest of the world uses 531 kHz to 1602 kHz with 9 kHz increments. | In the Americas the NDB's operate 530 kHz to 1700 kHz with 10 kHz increments.
