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. Full documentation on how to use the app is available here: http://www.blackcatsystems.com/iphone/dx_toolbox_faq.html Get your copy of DX Toolbox now, and you’ll always be up to date on current radio propagation conditions.}

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.

Needs an updated. Wonky interface, requiring tapping through rows, unsaved settings, strange UX. Please update.

This is a wonderful tool at a great price. I’m glad I found this app. To make this app even better, I think there should be an option near each parameter where I can tap for tips and definitions. I’m a newbie at this stuff, and it would be great to get in-app help regarding, say, how to interpret the A index, or whether a solar flux of 70 is good or bad, for example. Also, a dark mode would be fantastic.

This was once a great app with many useful areas of information reported that add to the understanding of HF propagation. It relies on getting its data from the web. Unfortunately, many of the links to the data are broken or discontinued. No attempt has been made to find alternative sources of data. There is so much broken it should no longer be offered for purchase!

Defintiv hilfreich, um die zu erwartende Verbindungsqualität abzuschätzen.

This app hasn’t been updated in a long time and I’ve noticed that the solar data it uses isn’t up-to-date. That causes the calls to be wrong. I’d love to see the developer update the software connection to the data sources. Thanks.

For a long time, the developer has been open-minded to accept and consider your feedback. As a result, I have corrected some of your feedback problems and adopted some suggestions. -Fixed: iOS14 Seconds Clock Widget truncated display problem fixed; The developer says that: A Nice morphing clock, shows me a geek cute flip clock & task alarm. The design is minimal, clean, modern and smooth. Supports customize the color scheme and with nice operation gestures. It's good choice to put it on the bedside and desktop as a digital clock. Nowadays, peoples would not like to have computers at home, then using the iPad or iPhone as clock should be environmentally friendly and perfect. The app can't be used as a screen saver when the screen is locked. In the process of using, you need to run the app all the time. it can set and disable the function of locking the screen, that is, keep the device on, and you need to open it in the app's setting. After settings, the system will not automatically turn off the screen when the app is running, which brings you an immersive experience which is similar to the effect of screensaver. In fact, due to system limitations, iOS does not support the so-called native screensaver function, so you do not have to work hard to find the so-called screensaver application. Therefore, before downloading, understand the content of app, read relevant strategies and tutorials, so as to avoid any psychological gap between the actual and the expected after downloading. In addition, you need to understand the payment mode of the app. The payment mode of the app is not a traditional buy-out system or a rising subscription system. After you pay to download, you may need to pay for more advanced functions, but remember that these are not necessary and will not affect your experience. With the product iteration, more free and paid functions will be added. If you do not agree, please terminate your purchase. All paid content has been prominently displayed on the AppStore page. Of course, if you think it's troublesome to unlock advanced functions one by one or you choose to support the developer all the time, the developer also provide another option, "Kronos" lifelong member. After becoming a lifelong member, you can use all now and future advanced content without any restrictions. Someone installed my App on the old iPhone 5 and put it on the wall. It looks good. Maybe this is the life solution you are looking for. Come to enjoy this video, life is your own, you can always find ways to make it wonderful: https://www.youtube.com/watch?v=RIC6jG3eyv8 Remind you: before downloading, please read the application description and update history carefully.
