DX ToolBox has dozens of windows providing a wealth of important information about current and forecasted radio, solar, and geomagnetic conditions.

It displays in real-time the following important readings:

Solar Flux
Solar Flux
Sun Spot Number
X-Ray Flux levels
X-Ray flares
Solar Wind
Earth's Magnetic Field
Proton and Electron Flux levels
Radio Blackout conditions
Geomagnetic Storm conditions
Solar Radiation Storm conditions
In addition, the last month's worth of Solar Flux, A-Index, K-Index, Sun Spot Number, and background X-Ray Flux are plotted. Audio alerts can be generated when solar flares, aurora, or disturbed geomagnetic conditions exist or are likely.
Graphs of x-ray flux readings from the GOES satellites may also be displayed.

A grayline map of the world is also available. Radio 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. Grayline propagation has been used by expert ham radio operators and DXers for years to catch elusive stations.

You can have the location of the currently transmitting NCDXF/IARU beacon displayed on the map as well. These beacons are run by ham radio operators around the world, and can be used to determine radio propagation conditions between your location and that part of the world.

You can also plot the great circle (both short and long) path between your location and another station, and compute distance, as well as the beam heading.

Radio propagation conditions can also be estimated between two points on the Earth.

21 maps of current D Layer Absorption levels are available for display

Grid square locations may be determined, as well as looked up on a map, which also shows the world's time zones.

Maps showing auroral levels, as well as the maximum F layer frequency (related to MUF) over various parts of the world are also displayed. Real-time images of the Sun from the SOHO satellite are also available.

The following radio propagation reports and forecasts are available:

So glad to finally see this update - This app had some issues with the previous version and I had to stop using it then I saw it had an update (had not used it since I updated to 10.9). So I updated the app and I finally have one of my favorite apps back working just like it use to.
