OpenWebRX WebSDR

OpenWebRX (software defined radio) tunes and listens to radio frequencies with most Web browsers on Windows, Linux, Android and iOS devices. OpenWebRX works with RTL-SDR dongles, AirSpy and SDRplay receivers. No client software is required.

The freeware OpenWebRX+ software can run on Linux machines, including the Raspberry Pi single board computer. Modes: FM, WFM, AM, LSB, & USB with built-in decoders for CW, DMR, SSTV, FreeDV, PSK31, FT8, JT65, WSPR, Packet and more.

You may find and listen to public WebSDRs around the world among those listed at https://www.receiverbook.de/

WebSDRplay Etiquette

OpenWebRX can accommodate several listeners at a time, but many WebSDR receivers can only tune one band at a time. If the status box in the lower left corner shows "Clients [1]" you alone are listening. If two or more clients are listening you are welcome to tune and listen within that band, but you should not change the band as that will interrupt the others' reception.

The WebSDR has selectable band profiles ordered by increasing frequency. Click on the down arrow in the receiver panel to select one of 15 amateur radio band segments from 80m through 33cm or general coverage segments covering HF, VHF and UHF from 500 kHz through 910 MHz.

WebSDR receivers may employ a Distill:AM band reject filter and a Flamingo FM band reject filter to avoid front-end overload from strong nearby broadcast stations. Therefore, the receiver sensitivity is decreased in parts of the AM and FM broadcast bands.
