WSJT-X 2.0 with Raspberry PI3 and SDRplay RSP1


WSJT-X and FT8 are enjoying increasing popularity. K1JT’s software, Joseph Hooton Taylor, is really easy to use and incredibly powerful. With modern radios, especially SDR transceivers, a PC or Mac, it has become really easy to establish worldwide radio connections. Even with bad antennas and low power, incredible ranges are possible.

For the reception and the monitoring of the FT8 frequencies a Raspberry PI3 with a SDRplay RSP1 on any screen is enough. Since I want to build myself a small portable digital HF scanner I use the original 7 inch touch screen display with a resolution of 800 x 480 pixels. Admittedly, a bit small, but it works. https://www.raspberrypi.org/products/

Installation:

Get a fast SD card. I am using a ScanDisk Extreme with 32GB. If the SD card has been used before it is recommended to format it before. https://www.sdcard.org/downloads/formatter_4/

Download the latest Raspberry RPI3 image from SDRplay. https://www.sdrplay.com/downloads/

Unpack the image and transfer it to the SD card. I use for it: https://sourceforge.net/projects/win32diskimager/

Take the SD card and insert it into the Raspberry PI3. Connect the screen, mouse, keyboard, SDRPlay RSP1 and power and start the operating system.

The EASYplay selection menu appears. Just test the RSP by starting GQRX. This program is also ideal for small screens.

Not important for the further procedure, but recommendable. Open the applications menu, preferences, Raspberry Pi Configuration. Activate VNC under Interfaces. This allows you to remote control the Raspberry Pi with a VNC client. The hostname is: raspberrypi, the user is: pi and the password root is: raspberry. Then, under Localisation, make the necessary settings for your country. Last but not least right click on task bar, under geometry position right and under Advanced minimise Panel when not in use. Then you have more space on a small screen. Finally, restart Raspberry Pi so that all settings take effect.

Install the latest version of WSJT-X. Open the browser in the Raspberry and enter https://physics.princeton.edu/pulsar/k1jt/wsjtx.html. Download the version: Raspbian Stretch, ARMv6, … there. At the time of writing this manual, the wsjtx_2.0.0_armhf.deb. For the installation we use the instructions under: http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main-2.0.0.html#INSTALL_LINUX

Strangely enough, version 2.0 does not work if I install it directly as described in the manual. If someone knows why, I would be happy to hear from you. So i install it with the Infos from Greg, KI7MT. http://wsprnet.org/drupal/node/5567

Call LXTerminal and enter the following commands:

sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 862549F9
sudo nano /etc/apt/sources.list
Add the following to the end of the sources.list file:
deb http://ppa.launchpad.net/ki7mt/wsjtx/ubuntu xenial main
Ctrl-X to save and exit.
sudo apt-get update # important

Then search for and install WSJTX under Settings, Add / Remove Software.

Start GQRX and then WSJT-X and make the appropriate settings in WSJT-X. WSJT-X detects the sound card and decodes the audio signals from GQRX.

If you not have WSJT-X 2.0 you can update it now:

Uninstall the old version of WSJT-X. To do this, search for WSJT-X in the Settings, Add / Remove Software and uninstall it.

Call LXTerminal and enter the following commands:

cd Downloads

sudo dpkg -i wsjtx_2.0.0_armhf.deb

sudo apt install libqt5multimedia5-plugins libqt5serialport5 libqt5sql5-sqlite libfftw3-single3

reboot

WSJT-X 2.0 should work now

Have fun…
