Shortwave radio enthusiasts worldwide are fortunate to have access to a web-based software-defined radio ("SDR") hosted at the University of Twente, Netherlands. This is a shortwave radio which allows anyone with internet access to listen to whatever the radio's antenna can "hear." Each online user can tune the radio independently- but the time of day, weather, and atmospheric conditions impact what the antenna picks up.

The location of the UTwente webSDR and its antenna are shown:
