Could be usefull if it would work

Nice idea but neglected. Most of the functions dont work any more: missing calculations, no images where they are supposed to be, dead links or missing information behind the menue. Not the money worth in this state.

Handy DX APP

Using a new IPhone 16… The app has a lot of links to solar data. Half of the info links don’t download. If the data does download, it takes a long time. ( cell network connection)

The graphs and pictures are small and hard to see on my IPhone.

The link labels could be little more informative as to the data origin.

Some of the downloaded data pages display about half of the document and will not scroll down to see the remainder of the document.

Some graphs’ X and Y axis are not labeled.

Some of the data, of course is useful. But, you have to hunt and peck through the copious menu items to determine which menu item will download or provide the common ham operator useful displayed data.

Overall, I use it occasionally. However, it’s just as convenient to go to the NASA’s Space Weather website.

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?

So much broken!

I used this app a lot when I got it, but then everything worked.

So many areas now no longer work due to broken links.

I tried contacting the developer, but they appear to have no interest in supporting this app any longer, they did not even reply.

Once recommended but not now. Give this one a pass.

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 !!!

FAQ

What does DX Toolbox do?

DX Toolbox provides up-to-date propagation information and solar conditions specifically for ham radio operators and shortwave listeners. It features tools to estimate HF propagation between any two global locations, displays a grayline map, and offers detailed solar and geomagnetic readings.

What are the key features of DX Toolbox?

Key features include propagation forecasting tools, a grayline map to identify enhanced propagation regions, great circle path plotting with beam headings and distances, aurora prediction maps, and ionosonde plot maps. It also displays various solar and geomagnetic readings and reports.

How much does DX Toolbox cost?

Based on the provided information, DX Toolbox is a paid application. There is no mention of free trials, subscriptions, or in-app purchases for core functionality.

What kind of information does DX Toolbox provide about propagation?

The app allows users to estimate current HF (Shortwave) propagation conditions between any two locations globally. It can generate graphs of these conditions for specific frequencies or times, and display MUF/LUF graphs. It also shows areas where signals can be heard based on frequency, power, and current space weather.

What solar and geomagnetic data is available?

DX Toolbox displays important solar and geomagnetic readings such as 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, and conditions like Radio Blackout, Geomagnetic Storm, and Solar Radiation Storm.
