DX ToolBox Version 6.2.2 released

Black Cat Systems has released version 6.2.2 of DX ToolBox for MacOS.

DX Toolbox searches the world for you, gathering information on solar and geomagnetic conditions that affect radio propagation. DX Toolbox also has several built in propagation forecasting tools. There are also databases of SWBC stations, and NDBs. Plus much more! Please take a moment to read through this documentation to see all the DX Toolbox features. An active internet connection is required to use DX Toolbox.

DX Toolbox displays in real-time the following important readings:

  • Solar Flux
  • A-Index
  • K-Index
  • X-Ray Flux levels
  • X-Ray flares
  • Solar Wind
  • Earth’s Magnetic Field
  • 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.

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

A grayline map of the world is also available, showing the daytime, dark, and most importantly the grayline region, where propagation is often greatly enhanced.

Propagation conditions can be estimated between two points on the Earth.
