I am running build-a-pi on another RPi - so maybe my expectations are messed up.
?
On a RPi 4 - running latest 32bit OS
?
After installing OS on SD card - and doing apt update and apt upgrade, I download and ran 73Linux.?
?
Lots of?
Gdk-CRITICAL errors.?
?
After reboot - there is a wide (maybe 1/4 screen) black vertical stripe. (is that where CONKY should be?() There is no 73Linux background image.
?
And i selected the Raspberry symbol (top left) to see the menu items. I had installed perhaps 15 items - many are missing. In particular WSJT-X is not on the Ham menu.?
?
FLRIG does work- and talks to my radio.
?
Pat menu works (up to a point) - fired up Packet modem and get an error - but I bet I have more configuring to do to get that to work.?
