Distance & Bearing Calculator

The Distance and Bearing Calculator allows amateur radio operators to calculate the great-circle distance and bearing between two stations. You can use grid squares, geographic coordinates, or select locations directly on the map. The tool is useful for antenna aiming, contest analysis, and general operating awareness.
