We recommend the powerful software "WXtoImg" for recording and decoding weather images with our receivers.

"WXtoImg is a fully automated APT and WEFAX weather satellite (wxsat) decoder. The software supports recording, decoding, editing, and viewing on all versions of Windows, Linux, and macOS. WXtoImg supports real-time decoding, map overlays, advanced colour enhancements, 3-D images, animations, multi-pass images, projection transformation (e.g. Mercator), text overlays, automated web page creation, temperature display, GPS interfacing, wide-area composite image creation and computer control for many weather satellite receivers."

Important Information About Kepler Data

The built-in function of WXtoImg to update Kepler data has stopped working. Please follow the instructions in the dedicated section below for a permanent fix.

Installation Notes

On Windows we strongly advise to use our pre-configured installation. If you want to use the original installation instead, please make sure to follow the steps below to correctly configure WXtoImg. If not configured correctly, WXtoImg will crash!

Configuring Original Installation

After starting WXtoImg for the first time, please go to Options > Active APT Satellites and uncheck NOAA 17 from the list of active satellites because this satellite has been shut down.

On the same window, change the frequencies of NOAA 18 to 137.9125 MHz and of NOAA 19 to 137.1000 MHz.

The last step is to update the Kepler data. As stated above, the internal functions of WXtoImg for updating Kepler data stopped working. You either need to update the data manually, or use one of the solutions from the section below.

Linux 64-Bit

To install the 64-Bit version of WXtoImg on Linux use the following command:

gunzip < wxtoimg-linux64-2.10.11-1.tar.gz | sudo sh -c “(cd /; tar -xvf -)”

To start the software with a graphical user interface type xwxtoimg.

macOS

WXtoImg for macOS is a 32-Bit application and therefore won't run on macOS 10.15 Catalina or newer.

Updating Kepler Data

WXtoImg's built-in function to update Kepler data no longer works, after the source of the data (celestrak.org) changed its top-level-domain. Since up-to-date Kepler data are imperative for the application to function properly, one of the permanent fixes presented below must be implemented to restore this functionality.

Keplers Updater for WXtoImg

Keplers Updater for WXtoImg is a tool we developed to replace the built-in function of WXtoImg to update Kepler data. It doesn't require any setup and is easy to use with a graphical user interface. It is compatible with Windows 7 and newer. Keplers Updater for WXtoImg is already included in our pre-configured installation.

To start the tool, unzip the file and double-click on Keplers-Updater.exe. To update the Kepler data, just press the Update Kepler Data button. The latest Kepler data will be downloaded and saved in the correct location. A more detailed description of the tool can be found on GitHub.

Simplified Version

We also created a simplified version of Keplers Updater that is compatible with Windows 32-bit, too. Use setup.exe to install the tool. It requires .NET Desktop Runtime 6.0.7 to run, which will be installed automatically.

Other Solutions

Using a Proxy Server

A solution to restore the built-in update function of WXtoImg is to use a simple proxy server that is able to handle the HTTP redirects of the data source. Such a proxy, wxtoproxy is available on GitHub and was made for WXtoImg. You can download wxtoproxy for Windows from this link:

Save wxtoproxy.exe in your WXtoImg installation directory. By default, this is:

C:\Program Files (x86)\WXtoImg\

From this point on, you must start WXtoImg by starting wxtoproxy.exe instead of using xwxtoimg.exe or the WXtoImg desktop shortcut. In WXtoImg, go to Options > Internet Options, enable Use Proxy Server and type 127.0.0.1 into Proxy Host and 8080 into Proxy Port. You don't need to do this last step, if you use our pre-configured installer. Now, the built-in function of WXtoImg to update Kepler data should work again.

You must not close the console window that opens with wxtoproxy.exe! Any messages saying 404 - Not found are expected and can be ignored.

If you are still using Windows XP, download wxtoproxy.exe with this link.

Manual Update

You can update the Kepler data manually by right-clicking the link at the top right of this page and choosing Save Target/Link As. Now save the weather.txt file either in the WXtoImg installation directory or in the configuration directory. The default installation directory on Windows is:

C:\Program Files (x86)\WXtoImg\

The configuration directory on Windows, which is hidden by default, is:

C:\Users\[your username]\AppData\Roaming\WXtoImg\
