Ham Radio-live on the internet

Ham Radio-live on the internet

when conditions are poor of the QRM on ham radio receivers is too high you can always tune in to one of the many SDR receivers which allow the user to listen to live ham radio broadcasts from a number of remote stations throughout the world.

This is Hackgreen an ex RAF bunker a one secret establishment 


Due to a number of updates from Google, there are times when this internet receiver does not work, try Firefox or windows edge instead.



Using Hackgreen SDR for Ham Radio nets is a real boom, it often makes the difference between hearing members of a radio net or not, many controllers keep an ear out on Hack Green, it is especially useful for a controller to hear QRP signals when conditions are marginal.


WebSDR (Web Software Defined Radio Systems) was developed by PA3FWM. The software server lets many users simultaneously tune the SDR to different frequencies to listen to. There is an ever-increasing number of servers being activated.
When I first posted this page, a few years back, there were only a few active WebSDR servers. Now there are 173 WebSDR servers in operation around the world (updated April 28, 2018).

Trawling the internet I found these SDR websites for Radio Ham use I am sure there will be more to come in the future.
