Monitoring real-time amateur radio activity is essential for DXers and contesters seeking rare contacts or tracking propagation. This online service aggregates DX spots from various **DX Cluster** networks, presenting them visually on a world map. Users can observe new spots as they appear, facilitating quick identification of active stations and potential openings. The platform offers filtering capabilities, allowing operators to narrow down displayed spots by specific bands such as 160m, 80m, 40m, 20m, 10m, and even VHF/UHF segments like 70cm and 23cm. Further refinement is possible by selecting the source continent of the spotter or the continent of the DX station, which assists in strategic operating. The service also includes a "Hot Now" list, highlighting currently active stations with recent spots. This dynamic display supports informed decision-making for pursuing **DX contacts** across different bands and geographical regions. -

Demonstrates a specialized DX cluster monitoring application, _DxWatcher_, designed for Windows environments. It processes DX spots received via Telnet/Internet, presenting them in a filtered table and a dynamic bandmap. The software integrates with transceivers, specifically the FT-2000, to read VFO frequency and enable one-click tuning to spotted stations. _DxWatcher_ version 1.0.3.0, released on 13 June 2020, includes minor bugfixes and improvements such as enhanced recovery from suspend mode. Key features include configurable bandmap position and size, automatic opening, and bolding of spots received within the last **10 minutes**. The application utilizes the standard _ctry.dat_ file for DXCC country analysis, allowing users to update it for current DXCC status. Source code, developed in C# with MS Visual Studio 2008, is freely available, encouraging modification and sharing while requesting retention of the original author's callsign. -

Its database is built within the SQLite environment, providing a robust and portable data storage solution for logging QSOs and managing station information. The program's architecture focuses on practical functionality for daily amateur radio operations. Operators can utilize NewLogOSH for contest logging, general DXing, and managing their station's contact history. The inclusion of FT4 and FT8 modes reflects current trends in digital communication, while RTTY and PSK support caters to established digital protocols. The DXCluster integration provides real-time spot information, aiding in DX hunting and propagation analysis. Its SQLite backend ensures data integrity and ease of backup, making it a reliable tool for maintaining comprehensive station logs. -
715 days, 6 hours, 58 minutes, and 29 seconds of uptime are reported for the YSFReflector-Dashboard by DG9VH, which monitors the IT C4FM SUD / ITALY-SUD reflector. This dashboard, compiled on December 1, 2017, provides real-time operational statistics for the reflector, including system information, disk usage, and connected YSFGateways. The dashboard also features a "Last Heard List" and an "All Heard List," displaying callsigns, durations, and timestamps (Europe/Rome) of stations active on the reflector. These lists offer a quick overview of recent activity, which can be useful for tracking **C4FM** traffic. While the resource is titled "IZ7AUH-6 DX Web Cluster," the primary content displayed is a **YSFReflector** dashboard. This suggests the platform might serve a dual purpose, offering both traditional DX cluster services and monitoring for Yaesu System Fusion reflectors. -

BeaconSpot.uk provides an accurate, real-time picture of microwave and VHF/UHF beacons operating across Europe, alongside a worldwide listing of 6-meter beacons. The platform allows users to retrieve detailed data for individual beacons, facilitating in-depth analysis of signal characteristics and propagation paths. Interactive maps visualize beacon distribution by frequency band and display spot coverage for each station, offering a clear geographical overview of active beacons. The system integrates real-time DXCluster spots, sourced from contributors like Alain, ON4KST, and Pascal, F5LEN, and enables users to submit outgoing spots directly to the DXCluster. Beacon keepers can manage their beacon data, receive email alerts upon being spotted, and track their station's ODX (Outstanding DX) records. For every received spot, the distance to the beacon is automatically calculated and displayed, aiding propagation studies. -
