A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.
See below links to popular WebSDRs used by our members and many radio enthusiasts around the world and you may want to take a look at Ian G0XBU’s YouTube video “How to use the WebSDR“.
