DX ToolBox for Windows

DX Toolbox searches the web for you, gathering information on solar and geomagnetic conditions that affect radio propagation. In addition, the last month's worth of Solar Flux, A-Index, K-Index, Sun Spot Number, and background X-Ray Flux are plotted. Maps showing aurorally levels, as well as the maximum F layer frequency (related to MUF) over various parts of the world are also displayed. A gray line map of the world is displayed

Propagation conditions can also be estimated between two points on the Earth. DX grid locations can be calculated, as well as located on a world map.
