Corrupted sBitx – How to reset the settings.ini
Before you replace files, try deleting (or renaming) your settings file, /home/pi/sbitx/data/user_settings.ini. I have had it several times where upon restart of the app or restart of the Pi, something goes wonky and deleting the settings file fixes it. I haven’t gotten to the bottom of it yet.
If you need to toss a hand grenade, I would do the following (First open a terminal with Ctrl-Alt-T and then type:)
mv ./sbitx ./sbitx.old
git clone https://github.com/afarhan/sbitx.git
