The Reverse Beacon Network (RBN) graph presents a dynamic visualization of amateur radio spots, specifically tracking CW, BPSK, and RTTY signals over the last 15 minutes. Users can filter these real-time spots by DX continent, spotter continent, and individual frequency bands, including **160m through 70cm**. The interface also offers a bandwidth reduction option, which is particularly useful for operators with limited internet connectivity. This resource provides a unique perspective on propagation conditions and station performance by aggregating data from various _Reverse Beacon Network_ nodes. It automatically refreshes every 10 seconds, ensuring that the displayed information is current and relevant for active DXers and contesters. The graph's Y-axis represents time, with each spot indicating activity within a one-minute interval. Beyond the primary RBN graph, the platform also features dedicated maps for both DXCluster and RBN data, including azimuthal projections. An additional FT8 graph is available, though noted as being under construction, indicating ongoing development to expand its utility for digital mode enthusiasts. The system was developed by HA8TKS, with the initial concept attributed to CT1BOH.

The GB7MBC resource provides real-time DX spotting information through both web and **telnet cluster** interfaces, catering to amateur radio operators seeking immediate updates on propagation and station activity. It integrates features such as a **JOTA cluster**, RBN (Reverse Beacon Network) data, and PSK Reporter spots, offering a comprehensive view of current band conditions and DX opportunities across various modes and frequencies. The platform also includes a forum for community interaction and detailed DX cluster statistics, allowing users to analyze historical spotting data. Users can access the cluster via a standard web browser or through a telnet client, providing flexibility for different operating environments. The inclusion of RBN and PSK Reporter data enriches the spotting experience by cross-referencing reported signals with automated reception reports, enhancing the reliability and utility of the DX information. This combination of real-time data, community features, and statistical analysis makes it a practical tool for DXers and contesters.

For radio amateurs seeking to verify contacts or identify stations from Tajikistan, the _Tajikistan EY Callbook_ serves as a dedicated online resource. This callbook, compiled and maintained by Irage M. Tursoon-Zadeh, _EY8WW_, offers a focused database of callsigns within the EY prefix region. It provides a practical utility for DXers and contesters aiming to confirm QSLs or prepare for operations involving stations in this specific geographic area, streamlining the process of identifying active hams. The resource's utility is particularly evident for those engaged in award programs like _DXCC_ or _WAZ_ where accurate callsign verification is crucial for credit. Unlike broader, worldwide callbooks, this specialized listing ensures high relevance and accuracy for its target region, reflecting the local expertise of EY8WW. Its direct focus on Tajikistan makes it a valuable, albeit niche, tool for operators with specific interest in Central Asian DX.

KB9AMG's Top WSPR Spots presents a focused online tool for monitoring **2-way WSPR reports**, specifically detailing propagation data from February 2026 through March 2026. This resource aggregates _WSPRnet_ data, allowing radio amateurs to observe weak signal propagation conditions across various bands. The interface is straightforward, presenting callsigns, frequencies, signal-to-noise ratios, and distances for each reported contact, which is crucial for understanding current band openings and signal paths. The utility of this WSPR spotter lies in its ability to quickly visualize global propagation. Users can identify active stations and assess signal viability over long distances, with reports often showing contacts spanning thousands of kilometers. For instance, a typical WSPR report might indicate a signal from Europe reaching North America with a _SNR_ of -25 dB, demonstrating effective low-power communication. This data is invaluable for planning DX operations or evaluating antenna performance under actual propagation conditions.
