WSJT-X 2.2.0 Beta for the Raspberry Pi 4

Advertisements

Recently, a new Beta Version of WSJT-X was released for testing. According to the release documentation there are several bug fixes and a change in the decoded of signals. Bug fixes are nice, but what peaked my interest is the improved decoding with FT8. Decoding now has three intervals, with the first starting at 11.8 s, followed by 13.5 s and 14.7 s. According to the documentation, this improves decoding by 10% or more on crowded bands .

Before installing the new software, I like to make sure my Raspberry Pi is up to date. It is also a good idea to make a back up image of your SD card. Unfortunately, during the update process power flashed and the Raspberry pi had to be completely reloaded in my case. I did not make a image before I started so it had to be loaded from scratch. For instructions on making a backup image click this link. To begin the update process type ” sudo apt update ” in the command line window.

Once that is complete, type ” sudo apt dist-upgrade “. This may take a while to finish updating. After it has completed, reboot the Raspberry Pi and download the WSJT-X file from the WSJT-X website.

In the command line window, navigate to the directory the file was downloaded to.

Once you are in the proper directory, type ” sudo dpkg -i wsjtx_2.2.0-rc1_armhf.deb “. This will install WSJT-X 2.2.0 . During my installation, errors popped up for a missing dependency.

To fix the error, I searched for the dependency in the add/remove software. After checking the box next to the results from the search, click apply. Qt 5 Multimedia module and its plugins will be installed.

To make sure WSJT-X was installed properly install the program again. It should not display any errors.

WSJT-X is now ready to be opened. A banner will pop up to remind you when the end of life for the Beta software is. Click OK and WSJT-X is ready to be configured.

Once WSJT-X was setback up, I was able to give it a couple test runs. There is a big improvement on decoding. Signals start to populate much faster. A nice and unexpected fix was in the logging portion of the software. In the previous version comments and power would not retain my entries. This version retains the information and only has to be reentered when power settings change.

So far I am very pleased with the version of WSJT-X. Since it is a Beta version, I am sure there are bugs, but have not fond any yet. If any major hick ups pop up, an updated post will be made.
