After the thunderstorm this summer, when most of our hardware was destroyed, a new WebSDR hardware has been developed.
Using 6 pcs of RTL-SDR Blog V3 dongles on a Dell server in direct sampling mode, we now offer a 6 band HF reciever.
The reciever is still running in beta, but as we need to test the load on many listeners, please use it as much as you like.
The reciever is online at http://websdr.sk4ko.com:8899/
Also try the YO3GGX Dan app for the web receiver. Search the PRXTX app and select the SK4KO receiver.
