WSJT-X is a computer program used by Amateur Radio Operators for weak signal communications. It is designed to send and receive the most basic information for a verified contact. This does not allow for rag chewing or any conversation. For more information about WSJT-X, visit there website.
Like many other innovations in Amateur Radio, WSJT-X has caused controversy. Many Hams say, “This program and its modes will be the end of Ham Radio”. If you look back over the history of radio, you will see similar fears with each new innovation. Fears like this date back to when spark gap transmitters were being phased out.
First open the main menu in and click Preferences. Then click “Add/Remove Software”.
In the Add/Remove Programs menu, there is a search box in the top left. Just type “wsjtx” in it and press enter. After the search is done, it will display the program and its supporting packages in the box on the right.
Check each box beside the programs that are displayed. Once checked, Click on “OK”. This will install WSJT-X.
The icon for WSJT-X is placed in the Sound and Video group in the main menu. You can make a new group and icon if you do not like it in the Sound and Video group.
Once you open the program, several windows will appear with warnings. Click OK on each one until they are gone. Most of the windows are due to WSJT-X not being setup.
To setup WSJT-X Click File and Settings.
In the General tab, it is required to enter your Call sign and Grid. The check boxes that have been changed are my preference and not required.
In the radio tab, I have entered the setting to connect my Yaesu FT-891.Check the Baud rate in your FT-891 if you have any issues. For physical connection of the FT-891, Read my post on the Yaesu FT-891 Sound Card Interface Cable and Getting Started with WSJT-X and the Yaesu FT-891 Transceiver.
Select the sound card that is connected to the Yaesu FT-891.
Once the basic settings are set , you should be able control the FT-891 and decode signals. Testing has gone well with the Raspberry Pi 4. I have WSJT-X running on a Pi 3 and the difference in performance is definitely noticeable. In a future post this Pi will be over clocked to squeeze a little extra speed out of the processor.
