Azimuth - The AZIMUTH program plots a world map in either azimuth (beam heading) or Mercator projections. If you specify your home location in latitude and longitude, the azimuth projection is centred on your location. The Azimuth map program can display Maidenhead grids - this is useful for 6m, 2m, and UHF DX communication display. Various features of the map are: Azimuth or Mercator projections , Maidenhead grid display, Simple map zooming, Print maps with adequate resolution up to one meter sized map

AZMap - Azimuthal maps generator - AZMap is a freeware Windows program for the Windows PC which will generate, display, and print an Azimuthal-Equidistance (A-E) map of the world, centered at any point on the surface of the earth (except very near the poles). The A-E map is also known as a Great Circle map since straight lines from the center point to any other point always fall along a great circle path and represent the shortest distance between the center and that point
