Save time by rapidly configuring the listed servers to the frequency and mode of your choice using this dynamic list! When the SDR renders in your browser, it will be on the frequency and in the mode you selected, also with a consistent and reasonable filter bandpass for either single sideband or AM.

1. Simply enter a frequency, select a mode, click ENTER.
2. After this page reloads, click on a server to open a new tab and start listening as configured.
3. KiwiSDRs on the OpenWebRX interface can tune anywhere from VLF through 30 to 32 MHz.
4. WebSDRs are limited to bands set up by the operator, depending on the hardware.

The software defined radio servers listed here have been selected for geographical coverage and quality of reception. Performance and coverage vary depending on hardware, internet bandwidth, and radio conditions at individual sites. This is not an exhastive list, as server availability changes on a daily basis! To see what is immediately available, visit the live online lists.

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!
