This morning I installed the zbitx Image on a uSD card and started it on my sBitx v2 device.
Apart from the hardware difference, the radio control panel started.
I tried to configure the wsjt-x program and my experience is the same as yours.
The CAT control does not work normally, i.e. nothing happens when I click on CAT.
It is as if the previously non-working version is installed here.
There is also a problem with the RPi clock display, because no matter how much I set the geographical location, it does not show the correct time.
