Web based software defined radio

Just stumbled upon an amazing remote controlled receiver available on the internet called WebSDR.

Unlike other radios available on the internet this one uses software to decode the spectrum coming in from the radio in such a way that multiple people can be listening to different frequencies simultaneously.

This system is hanging out the back of a PC at the Faculty for Electrical Engineering Mathematics and Computer Science at the University of Twente Enschede - The Netherlands. It looks wonderfully home brew.

Click and drag in the black area under the "waterfall" and you can tune. The great thing is that many users can be doing the same and streaming audio at the same time.

Great stuff!
