NovaSDR - PhantomSDR Plus - KiwiSDR - WebSDR
We have 4 different WebSDR-Servers running at Rigi Scheidegg (JN47GA) in the Swiss Alps at 1'660m for the HAM community. All our HF WebSDR-Servers are connected to the Wellbrook Loop. When we transmit (FT8, CW, SSB) with our DX station, SDR reception is briefly disrupted.
All WebSDR-Servers are operated via a reverse proxy server in order to be protected against DDOS attacks.
