ok, thanks for your reply and the links.
I decided to install icecast on a separate RPi running DietPi (great distro. !) which has icecast bundled. Now I just have to figure out how to link it RB rb 8-0 (the config files are XML).
Another issue i have is MLAT. It is "active" but there are no "stations"....
Otherwise, all is working fine.
Greetings
