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 Toolboxs 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

Pros and cons of DX Toolbox app for iPhone and iPad

DX Toolbox app good for

A quite interesting applet. Propagation map is really easy and useful.
As an avid ham and shortwave listener, I can heartily recommend this app for the wealth of useful information it provides. Well done!!
This app is really appreciated and it is really helpful. I would like to mention that the tech support is also awesome. 73 de Jeff | VA2SS
Its a Swiss knife for an Ham portable DX activity. Very complete and updated.
Promises to be useful - only its unstable (crashes repeatedly). Im using an iPad Air 2 with iOS 10.2. Were it not for the crashes, Id have rated it 5-Stars - for the comprehensiveness and innovativeness.

Some bad moments

Looks like a work in progress, this app is not ready for release, needs serious work. Can I get my money back?
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 swls like myself find it interesting and helpful.
Looks pretty good so far. The Propagation for Time calculation crashes the app hard every time I attempt to use it.
This really feels like beta software. The interface is bare bones and feels unfinished. In the Setup menu, why do you have to enter your lat/long by hand, when the iPhone can usually figure that out by itself. The purpose of the buttons under the gray line map is unclear. Graphs need titles and legends and descriptions and such. This isnt very useful in its current form. A shame, because I WANT to like it.
Contains some handy information, but nothing you cant get from other sources using a web browser. The user interface needs A LOT of work; leaving the program and coming back starts you at the main page again, no access to internal GPS for obtaining coordinates, creating "Custom Locations" rotates your screen whether you want it or not, etc.
This app is great and has really helped me get a tactical edge on my QRP operations. It is my go to app when using my KX3.
