QSO extractor for WSJT-X: grab logfiles and extract QSO's. Currently working with FT8 and WSPR modes.


2 Modes available: Local File or Remote Raspberry.

Local File

Simply load ALL.TXT file from WSJT-X to extract QSO. Callsigns are unique, so only 1 QSO per Callsign per Band will be logged.


Remote Raspberry

Connect to a remote Raspberry and grab QSOs.

On your raspberry, you have to install LightHTTPD server (a very simple web server) and create a folder named "archivio" on your webserver (/var/www/html/archivio) then add a simple shell script to your /etc/crontab file to perform logfile rotation.

Create a file called in your home directory

# LogFile rotation for WSJT-X
data=$(date +%F);
mese=$(date +%m);
anno=$(date +%Y);
giorno=$(date +%d);
ore=$(date +%H);
minuti=$(date +%M)


cartella="/home/pi/.local/share/WSJT-X/" ## Change path to match your own home directory
destinazione="/var/www/html/" ## Your Webserver root

killall wsjtx

cp $cartella/ALL.TXT $destinazione$archivio$nomearchivio
cp $cartella/ALL_WSPR.TXT $destinazione$archivio$nomewspr
rm $cartella/ALL.TXT
rm $cartella/ALL_WSPR.TXT

rm -f $cartella$wavfiles/*.wav
ls -1 /var/www/html/archivio/*.txt > /var/www/html/archivio/files.index ## Here also change WebServer root
sleep 2;
/usr/bin/wsjtx &

Make the file executable by typing: chmod +x

Now edit your /etc/crontab file and add this 2 lines:

*  *    * * *   pi   cp /home/pi/.local/share/WSJT-X/ALL.TXT /var/www/html/
0 */4 * * * pi export DISPLAY=:0 && /home/pi/

Explanation of crontab file:

  • Every minute the ALL.TXT file will be copied into local webserver folder
  • Every 4 hours WSJT-X will be stopped, logfiles rotated and restarted


By your PC side, configure SWL WSJT Logger to fit your raspberry webserver address / archive folder.

Each 4 hours you'll se a new logfile available to exctract QSOs.
