DX clusters aggregate real-time amateur radio spot data, enabling operators to identify active stations and propagation conditions across various bands and modes. DXWatch offers a web-based interface for this essential operating tool, allowing users to filter spots based on specific criteria such as band, mode, or callsign. The service integrates features like a customizable filter system and an external widget for embedding spot data on other platforms, enhancing its utility for DXers and contesters. Operators can access worldwide spot data, with options to zoom into specific regions like the US, Europe, or the North Atlantic, facilitating targeted DXing efforts. The platform also includes a watchlist feature for registered users, enabling personalized tracking of desired stations or entities. Real-time data on solar flux index (SFI), A-index, and K-index are displayed, providing crucial propagation insights alongside the DX spots.

Presents a web-based DX cluster interface, F5LEN Webcluster, which functions as a member node within the broader European DX Cluster network. It displays current DX spots across a wide range of amateur radio bands, from VLF through SHF, including specific bands like 1.8 MHz, 144 MHz, and 10 GHz, as well as satellite operations on QO-100. The service offers filtering options for various modes and activities, such as CW, QRP, IOTA, and specific VHF/UHF bands. Operators can access real-time propagation data, including Solar Flux Index (SFI), Sunspot Number (SSN), Kp index, and Auroral activity (Au), alongside tools for solar forecasts and tropospheric ducting predictions. The platform facilitates DX spotting by providing a centralized point for sharing and viewing contact information, aiding in DX hunting and contest operations. It also includes links to an Atlas, Sun tools, and a mobile version for portable access.

DX_Central, a compact desktop application, provides amateur radio operators with critical propagation data by aggregating solar statistics and imagery from various authoritative sources. This includes real-time information from agencies like NOAA and NIST, offering insights into current space weather conditions that directly impact HF propagation. The software is designed for both Linux and Windows operating systems, making it accessible to a broad range of hams. It presents a concise overview of solar activity, which is essential for planning DX operations and understanding band openings and closures across the HF spectrum. Operators can utilize the displayed solar flux index, K-index, and other relevant parameters to make informed decisions regarding their operating times and target bands, optimizing their chances for successful long-distance contacts.
