Where are the European university stations?

There are hardly any

Not true. Just randomly one I found: https://www.unicross.uni-freiburg.de/unifm-884/

They just need to be indexed like the American ones. I am pretty sure there are Canadian ones (and from other countries) as well.

I'm looking for the inverse. I want an AM/FM tuner that I can stream audio from. It used to be I lived in a place without enough internet connectivity for streaming. Even still, AM/FM radio broadcast still worked. *If only there was a radio tuner that I could attach to a raspberry pi, then stream the audio from it.

It's possible to solder a wire to a GPIO pin of a Raspberry Pi and use a program to broadcast FM from that. I've done this very thing in the past. I did it with a first gen RPi, but I think the actual code to make this work with other RPi models may have changed. Google is your friend for this.

For me the performance was quite good. I could pick up the music anywhere within ~100 ft from a short 6cm wire soldered to a GPIO pin.

A great idea.

If you're ever in a strange city in a rental car, and want to find a radio station: look between 88 and 92 on the FM dial. That range is reserved for non-profit stations, like these.

You'll also find the local NPR station(s) down there, if there are any.

You could attach an rtl-sdr to a raspberry pi and locally host a websdr server (https://github.com/jketterl/openwebrx is a good open source one). The rtl-sdr doesn't have a high enough sample rate to cover about half of the commercial fm broadcast spectrum at a time where you can see quickly switch between stations in that portion e.g. 89-94 Mhz. Going to the other half just requires having two different modes and switching between them in the websdr interface.

Or just having two sdr's.

Great Project! I think the UI ist really well made for what it aims to do. And I think something to help independent radio is always a great thing.

As some here in the forum I did shows back then on ("independent") stations, love the medium and think there is (too less heard) creativity out there.

..that's also why I built something similar. But with the focus on the shows(!) https://radiobird.fm

Just a german version right now and mostly european stations but with a plan to change that.
