DBHam vs Ham Radio Logbook

Compute distance and bearing using Maidenhead location. This was originally intended for use by amateur radio operators who participate in microwave communications however it can be used by any ham in order to determine a distance and bearing to another radio amateur. If you want to see maps of the source and target with annotations and overlays as well as be able to touch the map to determine the grid at a particular point, then take a look at our App: DBHamPlus.
