Distance and Bearing Tools for Ham Radio Operators
Find online calculators and maps to determine distances, beam headings, and QTH locators for effective amateur radio communication.
Accurate distance and bearing calculations are essential for many amateur radio activities, especially for operators pursuing DX on HF bands or aiming directional antennas. Knowing the precise heading to a distant station helps optimize antenna performance and improve signal reports during QSOs. These tools are also invaluable for understanding propagation paths and planning antenna projects for specific regions.
Hams can find various online tools to generate personalized azimuthal maps, such as those from NS6T, which show beam headings from their QTH to the rest of the world. Other resources provide great circle distance calculators and QTH locators, helping operators determine precise bearings and distances to DXCC entities or IOTA groups. Some utilities even allow for line-of-sight calculations, useful for VHF/UHF work, or convert street addresses to latitude and longitude for precise station positioning.

The page automatically generate a Great Circle Map (GCM) for ham radio operators based on the IP address or by a given QTH locator. The GCM generated, unlike traditional maps of this type, has been rendered in an elliptical shape instead of a circle. This provides an expanded view horizontally thus making it easier to interpret. The map base is colored with each continent colored differently for easier recognition. The color code of the continents is given below the map for easy reference -
