WebSDR Servers - KiwiSDR - PhantomSDR Plus
We have 4 different WebSDR servers 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. WebSDR is a project initiated by Pieter-Tjerk de Boer providing access via browser to multiple SDR receivers worldwide covering the complete shortwave spectrum. When we transmit with our DX station, SDR reception is automatically interrupted during transmission.
- WebSDR for HF (10m,12m,15m,17m,20m,40m,80m)
- WebSDR for 2m and 70cm
- PhantomSDR Plus 0 - 30 MHz in one Waterfall
- KiwiSDR 0 - 30 MHz in one Waterfall
The availability of our WebSDR HF server is not 100%. At the moment we are victims of a DoS attack

WebSDR for HF
7 Airspy HF+ Discovery SDR Receivers for 10m, 12m, 15m, 17m, 20m, 40m, and 80m running on a HP EliteDesk 800 G2 PC [Intel Core i5-6600T @ 2.70 GHz, 16GB RAM, 250 GB SSD Disk, 7 USB-Ports, Debian 10 Linux (64 Bit)]. The Antenna signal from the Wellbrook Loop is connected to an ELAD ASA 15 and ASA 16 active antenna splitters using the CCMC30 Common Mode Noise Filter.
WebSDR for 2m and 70cm
WebSDR for 2m and 70cm with 3 Neoolec RTL-USB SDR sticks connected to our Diamond X-50NA Antenna with a high-end pre-amp and passive antenna splitter is running on a HP EliteDesk 800 G1 PC [Intel Core i5-4570T @ 2.9 GHz, 16 GB RAM, 250 GB SSD Disk, 6 USB-Ports, Debian 10 Linux (64-Bit)]. Strong signals from the nearby (50m) HB9ZG relay-station (C4FM, DMR, DSTAR) will cause some interference (horizontal lines).
PhantomSDR Plus 0-30 MHz Waterfall in one Browser Window
One of the first public PhantomSDR Plus server in Switzerland. The whole HF-Band 0 - 30 MHz in one Waterfall with one RX-888 MKII SDR connected to our Wellbrook Loop is running on a HP Elite Pro 800 G2 PC [Intel Core i7-6700 CPU @ 3.4 GHz, 16 GB Ram, 256 GB SSD-Disk, 7 USB-Ports, Ubuntu 22.04.4 (64 Bit)]
