This is what I've done so far in a Fedora 41 toolbox:
?
sudo dnf install gnome-radio gnuradio{,-{devel,doc,examples}} python3-gnuradio goodvibes radiotray-ng ?gqrx fllog rtl-433{,-devel} LinLog fbb{,-{doc,gui}} soundmodem{,-devel} tlf cqrlog hamlib{,-{c++{,-devel},devel,doc}} python3-hamlib ax25-apps flnet gr-rds{,-{devel,doc}} klog klog twlog xpsk31 lpsk31 rust-hamming+default-devel xconvers xfhell callgit dxcc dxcc-gui fldigi flarq flrig flmsg flamp fllog flnet flwkey flcluster

That brace-expands to:

I have a lot to explore now!
