I wouldn’t say unknown, as it’s a staple of the shortwave and ham radio communities, but websdr.org is a place where people stream software defined radio feeds from around the world. It’s not like a traditional internet radio station where you have an audio stream of a single station. You pick an SDR server hosted by a volunteer, and then you’re given a frequency input, modulation selection, and waterfall display as though you were listening to an actual shortwave radio.
I know it’s well-known because Eastern European stations were swamped during Russia’s initial invasion of Ukraine in 2022.
