A few days ago I tried to use RPi as a Icecast2 server. It should transport some audio over ip pakets from A to B. With my new soundcard it seems to work.
On my Ubuntu notebook I started fldigi then to deocde a few cw contesters doing their job.
Please note that this is just a POC based on the good work of DK7MW.
