In Germany we quite a few really cool alternative radio stations. They all have their local frequencies, shows and so on, but also share a German-wide morning show. It’s mostly recoded by the bigger projects, like in Berlin, but otherwise it would just take too much resources from small volunteer run stations.
Assuming you speak German: https://www.freie-radios.de/
Or here a audio platform where a lot of their content is posted afterwards, where you can discover stations and shows: https://www.freie-radios.net/ (albeit those are confusingly similar URLs)
