Are you a ham radio operator or shortwave listener, in need of up to date propagation information and solar conditions? DX Toolbox features several propagation forecasting tools, allowing you to quickly and easily estimate current HF (Shortwave) propagation conditions between any two locations in the world, and is ideal for the ham radio operator, shortwave listener, or other radio enthusiast. Radio propagation conditions can also be estimated between any two points on the Earth. Graphs of these conditions can be generated for a given frequency or time, and MUF/LUF graphs can 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 radio operators and DXers for years to catch elusive stations. A plot the great circle (both short and long) path between your location and another station is also displayed, as well as the beam heading and distance. The location of the currently transmitting NCDXF/IARU beacon can be displayed on the map as well. The propagation map displays the areas of the world where your signal can be heard (or a signal can be heard from), based on the frequency, transmitter power, and current solar flux, date, and time. Maps showing ionosonde plots of foF2, foEs, and hmF2 data from various locations around the world are available. The MUF and skip zone can be calculated based on foF2 and hmF2 values. Aurora prediction maps for the northern and southern hemisphere are available. DX Toolbox displays the following important solar and geomagnetic readings: Solar Flux A-Index K-Index 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 Graphs of x-ray flux readings from the GOES satellites may also be displayed. The following radio propagation reports and forecasts are available: WWV Geophysical Alert 27 Day Space Outlook 45 Day AP Forecast Geomagnetic Data Daily Geomagnetic Data Daily Particle Data Daily Solar Data GEOALERT Daily Magnetometer Analysis Reports Hourly Magnetometer Analysis Reports Predicted Sunspot Numbers and Radio Flux Report of Solar-Geophysical Activity Solar and Geophysical Activity Summary Solar Region Summary Weekly Highlights and Forecasts Current Space Weather Indices Space Weather Event Reports Daily Space Weather Indices Summary of Space Weather Observations 3-day Space Weather Predictions SEC Space Weather Alerts In addition, 21 maps of current D Layer Absorption levels are available for display.

Doesn’t work anymore
I can’t get most of it to work anymore. None of the maps work. Only the home page. What gives?
Great for someone learning
I started keying when I was 13 years old I will be 51 this year but I never gotten this serious about amateur radio, my past experiences enabled me to pickup very quickly on this app and I find the propagation map to be extremely accurate for all frequencies, I tested the map trajectory on frequency 27.385 LSB and I got skip from those areas the map predicted, your transmission wattage is also taken to determine proper propagation prediction from app. Get a good SWR Meter to ensure your getting out !!! Call Sign: 1771AF ( self appointed not official yet ) ch 38 LSB 27.385
A Must-have...
The iPad version is extremely useful, especially when mobile Dxing. Love it.
It works
It works good, supplies all the data it says with an online connection. Gray line map is useful. Read the help section in the upper right corner before using and you will have no problems. A more detailed tutorial would be nice though. Geared toward hams, but swl's like myself find it interesting and helpful. NEEDS TO BE UPDATED, Doesn’t all work with ios15.1.
Needs work
The graphs do not show values in the x axis. Location entry for stations do not support a grid square. Did this app make it through testing for iphone 12? I am requesting a refund.
Solar image support
With latest IOS update solar images no longer work or are coincidentally no longer a available. Great app other wise.
2021. Woefully outdated.
Needs an updated. Wonky interface, requiring tapping through rows, unsaved settings, strange UX. Please update.
Updates for iOS 10.3. Updated data source for Aurora images.
