enthusiasts.

DX Toolbox helps amateur radio operators and shortwave listeners
estimate radio propagation conditions. Several propagation
forecasting charts are available to estimate signal levels and path
conditions between any two points on the Earth.

A propagation forecast map shows the estimated signal level for a
given frequency from all parts of the world, for given solar
conditions, and the time of day and day of year. A plot of the
expected signal levels between two points on the Earth for all 24
hours of a day may also be graphed.

A grayline map of the world is also available. Propagation between
locations within the grayline region of the world is often greatly
enhanced. DX Toolbox's grayline map makes it easy for you to
determine where those locations are.
