See also the Skywavelinux SDR Map. Remember, though, that the map presents a full set, with both good and not-so-good servers plotted.

The software defined radio servers listed here have been selected for their reception quality. Performance and coverage vary depending on hardware, internet bandwidth, and radio conditions at individual sites. This is not an exhastive list, as server are excluded for low SNR. The list updates automatically, so be sure to bookmark it and come back often!

During peak operating periods, it may be difficult or impossible to use some of the sites. The KiwiSDRs have limited channels available. WebSDR servers can take more users, up to the point where CPU capability and internet bandwidth are limiting factors.

Software defined radio servers listed here are operated by volunteers, bearing their own expenses for the equipment and bandwidth. Be sure to do what you can to support those sites - linking to them, promoting them among your fellow radio listeners, and donating if they have set up a patronage process. To the server operators: we appreciate your effort! There are too many places in the world which lack good broadcast programming or are hampered by RF noise. What's more, there is something important in the ability for an average person, anywhere in the world, to access signals from places where "things are happening."

If you find interesting action on the bands, give some thought to making an audio recording or screen capture video to share on sites such as YouTube or Soundcloud
