The folks at University of Twente has installed a software defined radio receiver and connected the same to internet. I have been listening to this radio for quite some time now. You don’t need an amateur license to listen 😀 to it.( so give it a try) The receiver can be accessed from here . This SDR can be tuned to 80m 40m and 20m. It has got excellent signal quality and runs on minimal hardware. Look at this picture to see how simple an SDR can be. Detailed information of the set up is available here
