I have created a Bookworm 32GB SD card (fully updated) and booted a RPI4 4GB module from it without problems.
I downloaded and installed (apt get install ...) wsjtx and jtdx. Both will load but with the Wayland desktop the main GUI cannot be moved / repositioned (as previously stated).
By changing the desktop to X11 and rebooting, both wsjtx and jtdx load and appear to work as they should.?
You must also enable VNC from the X11 desktop to be able to remote in. TigerVNC remotes into the Wayland desktop and also the VNC desktop (with a security warning).
PiHut has shipped RPI5s starting today.
I hope this helps those who will try Bookworm OS for ham applications - others will also need to report issues with other ham apps.
Ham Radio is all about experimenting and learning!
