I run the WEB SDR IO group which is primarily aimed at WEB SDR admin's and owners with the aim of sharing experiences and technical expertise relating to operation and running of WEB SDR's
I also operate a number of public KiWi and other WEB SDR's, which cover various ranges of frequencies, which are located in the South West of the UK.
0-30MHz - Very good performance and low noise floor, probably one of the best in the world.
0-30MHz - New KiWi sdr V2 on test. Also very good performance and low noise floor, probably one of the best in the world.
0-65MHz - Very good performance and low noise floor, which also covers the VHF Low bands
Websdr covering 40, 50, 70, 144, 432, 434MHz & 10GHz Amateur Bands
OpenWebRX with a mixture of VHF and UHF Bands
0-30MHz - Very good performance and low noise floor, at another site in the South West UK
0-30MHz - Currently using a temporary antenna and its performance is not too good, however it can be useful for monitoring the VLF bands
Unfortunately our popular SW, VHF, UHF & Microwave WEB SDR at Farnham had to close down due to a change of site ownership.
Most of this has now been reactivated at the other sites.
