A live map of current KiWiSDR receivers available on the network. It allows users to explore a directory of web-controlled receivers for listening to HF and VHF stations worldwide. The site provides access to remote ham radio stations online, making it a valuable resource for amateur radio operators.

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.

The Roma2 WebSDR provides remote access to a software-defined radio receiver situated in Rome, Italy, enabling users to listen to various amateur radio bands. It features a user-friendly web interface with controls for audio gain, DSP filtering, and bandwidth selection, including options like **2.4 kHz**, **3.0 kHz**, **4.0 kHz**, and **6.0 kHz** filters. The system supports both desktop and mobile device access, with a dedicated mobile version available for optimized performance. Operating as part of the _ROMA SDR Network_, it logs user activity, automatically recording time, frequency, and DXCC information for each session. The platform also addresses common browser-specific audio issues, such as white noise in _Chrome_, by suggesting workarounds like muting/unmuting or using alternative browsers like Firefox.

Linux for shortwave and amateur radio monitoring. Supports popular SDR hardware and online streaming from KiwiSDR, WebSDR, and Spyserver sites. Articles about using Linux with your SDR devices.Skywave Linux, an innovative operating system, leverages cutting-edge technology for seamless access to radio signals globally. Ideal for regions with limited internet access, it effortlessly connects to a network of SDR servers, offering high-performance SDR operation without the need for extensive hardware. With pre-installed and configured SDR software, Skywave Linux simplifies signal discovery and operation for all users.

A searchable database of online websdr receivers, lists OpenWebRX, KiWi SDR and WebSDR from all over the world, providing a web interface to search and filter links to websdr

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.

Monitoring radio communications through web-accessible Software Defined Radios (SDRs) has become a popular facet of the hobby, and Receiverbook serves as a centralized directory for locating these remote assets. The platform aggregates listings for both **OpenWebRX+** and **KiwiSDR** installations, providing a gateway to a diverse array of frequencies and operating modes. My own experience with similar directories highlights their utility for casual listening, DXing, and even troubleshooting local RFI by comparing signals across different geographic locations. The directory details specific receiver locations, from Bedford, England, to Marahau, New Zealand, and Berlin, Germany. Each entry often specifies the supported frequency ranges, which can span LF, MF, HF, VHF, and UHF bands, including dedicated segments like 80m, 40m, 2m, and 70cm. Many listings explicitly note support for HAM radio, broadcast services, and public two-way radio, making it a versatile tool for various listening interests. Beyond general frequency coverage, some entries provide granular details about the underlying hardware, such as the **SDRPlay RSP1A** or RTL-SDR Blog V3, and even the antenna types employed, like the Sirio Gain-Master. This level of detail is invaluable for serious SWLs and hams looking to understand the capabilities and limitations of a particular remote receiver before tuning in.

The DX Jungle SatTracker is an interactive online tool designed for real-time amateur radio satellite tracking. It incorporates live Doppler correction, AMSAT satellite status, and pass predictions for various active amateur radio satellites such as ISS, SO-50, FO-29, and RS-44. The platform calculates real-time uplink and downlink frequencies, adjusting for Doppler shift, and displays satellite footprints and orbital paths on a map interface. Users can select specific satellites and input their grid square for localized pass predictions. This service integrates WebSDR support, allowing users to listen to satellite passes live without requiring a physical radio, and offers Companion radio control capabilities. Orbital data is sourced from CelesTrak, while radio frequencies are derived from AMSAT and SatNOGS. The interface provides options to filter for FM repeater-only satellites and displays active passes, ordered by the next available pass, facilitating timely operational planning for satellite enthusiasts.
