On this page you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio. Provided by PI4THT

This WebSdr is located in England UK at the Nantwich Secret Nuclear Bunker, formerly R.A.F. Hack Green

A multiband WebSDR receiver system, located in Bolton, England accessible via the RSGB web site

This online WebSDR is located near Corinne, Utah, has coverage on all U.S. amateur HF, MF and LF bands, 2 meters, the bottom 1 MHz of 6 meters, and several shortwave broadcast bands.

This WebSDR, hosted at Goonhilly Earth Station in Cornwall, enables you to listen to the Qatar OSCAR-100 Narrow band transponder onboard the Es'hail-2 satellite.

CATSync V1.30 integrates OpenWebRX support, expanding its capability to synchronize a local amateur radio transceiver's CAT control with a broader range of public WebSDR receivers. The software facilitates real-time frequency tracking, allowing the operator to adjust their physical rig's VFO and observe the connected WebSDR instantly follow the tuned frequency. This functionality is crucial for remote listening, signal comparison, and verifying propagation conditions across different geographic locations using a familiar hardware interface. The application supports both the classical WebSDR interface and KiwiSDR platforms, providing a consistent control experience across various online SDR deployments. It bridges the gap between local station operation and the vast network of globally distributed software-defined radios, offering a practical tool for DXers and contesters. CATSync is designed for Windows and Linux environments, with Android compatibility noted, making it accessible to a wide user base seeking to leverage WebSDR resources with their existing station setup.

WebSDR receiver located near Krizevci, Croatia with 0-2 MHz, 60-80 meters band and 40-49 meters band

This is a WebSDR receiver, located in Friedrichshafen, Germany (at Lake Constance) using a multiband dipol and a FUNCube Dongle Pro+.

Listen to online WebSDR located in Andorra Europe. Four receivers on 60m, 20m, 40m, and 80m, connected to a dipole antenna direction East/West

This is a 50 MHz WebSDR receiver, located in Ashford, CT, USA FN31VU using a deltaloop turnstile horizontally polarized omnidirectional antenna.

Examines current amateur radio satellite operations as of May 2026, providing a practical overview for hams interested in making their first satellite QSOs. The resource differentiates between Low Earth Orbit (LEO) satellites, such as the _ISS_, SO-50, RS-44, FO-29, AO-7, and GreenCube, and the geostationary QO-100. It highlights the distinct operational requirements for each, noting that LEO birds necessitate real-time tracking, antenna rotation, and Doppler compensation. The article emphasizes the critical practice of listening before transmitting and outlines methods for monitoring QO-100 in real time via the Goonhilly Earth Station WebSDR. It also covers tracking LEO satellites using tools like N2YO.com, Heavens-Above, and amsat.org/status. The author's experience with these platforms informs the guidance on equipment considerations and operating practices, ensuring hams understand the nuances of satellite communication in 2026, including the significant impact of QO-100 since its 2019 launch.
