A more faint line will also be drawn showing the long path. The great circle (shortest) path between your location and the other station will be drawn, with the beam heading and the distance in kilometers. The call of the beacon is also displayed.

If you select a ham band (20, 17,15, 12, or 10 meters, or OFF for none) the map will update every 10 seconds, showing the location of the currently active NCDXF/IARU beacon for that frequency. That is, if you are are in the grayline, then often you will find excellent propagation conditions to/from other locations also in the grayline.ĭue to the tilt of the EarthÕs axis, the shape of the grayline changes throughout the year, so that certain stations may only be in the grayline along with your location at specific times of the year, if it all. Propagation is generally enhanced between regions in the grayline. This tool displays a map of the world, showing the day and night regions, and the important grayline region between the two. Degrees are entered as positive decimal numbers for North and East, negative for South and West. Then tap an entry to edit the name, longitude or latitude.

Tap Edit to delete an existing entry to add a new one. This allows you to enter in your own set of locations for use with the various propagation forecasting tools. The color mapping ranges from violet for a weak signal, to red for a strong signal, using the same color order as in a visible light rainbow (violet, blue, green, yellow, orange, red). A plot for the entire day will be generated showing estimated signal levels for the range of frequencies. This tool allows the signal strength for a particular path to be estimated for the range of frequencies over which propagation is expected.Įnter the solar flux, transmitter power, date, and the two locations (location A is pre-set to your location as set in the Preferences) and tap Calculate. A plot for the entire day will be generated showing estimated signal levels. Enter the frequency in MHz, solar flux, transmitter power, date, and the two locations (location A is pre-set to your location as set in the Preferences) and tap Calculate. This tool allows the propagation for a particular path to be estimated. Degrees are entered as positive numbers for North and East, negative for South and West. You can use Custom Locations to enter in your own locations. Locations can be directly entered in decimal degrees (such as 37.5), or tap either Loc A or Loc B to bring up a list of pre-entered locations. A plot for that hour of the specified day will be generated showing estimated signal levels between 0 and 40 MHz.

This describes the various features of DX ToolBox, and how to use them:Įnter your longitude and latitude here. The program offers a wide variety of radio propagation forecast tools.IPhone /iPad Shortwave Radio Propagation AppĭX Toolbox for the iPad/iPhone/iPod Touch.The application offers detailed information about various readings and parameters.The program lets you see data in real time about various essential readings, such as A-Index, X-Ray Flux levels, Solar Wind, Proton and Electron Flux levels, Geomagnetic Storm conditions, Solar Flux, K-Index, Sun Spot Number, X-Ray flares, Earth's Magnetic Field, Radio Blackout conditions, and Solar Radiation Storm conditions. The program is suitable for shortwave listeners, ham radio operators, and many other radio enthusiasts.ĭX ToolBox comes with a modern-looking interface that offers detailed information about geomagnetic and solar conditions, forecasted and current radio, and more. The program includes multiple propagation forecast utilities, enabling you to easily and quickly estimate the current shortwave (HF) propagation conditions between any two points on the Globe. DX Toolbox is a small yet efficient utility that will search the web for information on geomagnetic and solar conditions that might have an effect on radio propagation.
