The website offers a comprehensive guide on high-frequency (HF) skywave propagation for amateur radio operators. It explains HF radio propagation fundamentals, including electromagnetic wave properties, HF bands, and propagation modes like skywave, ground wave, and line-of-sight. The site focuses on the ionosphere's critical role, influenced by solar activity, in refracting HF waves for long-distance communication. Real-time monitoring tools such as DX clusters, beacons, and digital modes like FT8 assist users in tracking band activity and propagation conditions globally. Forecasting methods are detailed, highlighting scientific insights into solar-terrestrial interactions and ionospheric variability. The guide also covers advanced topics like NVIS and gray line propagation, ionosonde data, and propagation prediction models, making it a valuable resource for ham radio enthusiasts aiming to optimize communications

OpenHamClock is a modern, open-source dashboard for amateur radio operators, designed as a web-based successor to the original HamClock. Deployable locally on a Raspberry Pi or via the cloud, it centralizes essential DX operations into a single, intuitive interface. At its core is an interactive world map that visualizes real-time DX spots, signal paths, satellite tracking, and POTA activators. The software seamlessly integrates critical tools like WSJT-X, DX Cluster, and PSKReporter for monitoring digital traffic. Additionally, it provides vital environmental data, including real-time space weather indices, solar activity, and personalized HF propagation predictions. With customizable themes and a modular architecture, OpenHamClock offers modern operators comprehensive, at-a-glance situational awareness of global radio conditions

Shortwave and Amateur Radio Log (SWLog) is a modern suite of applications that provide logging and remote control for amateur radio and shortwave, utility, and broadcast listening. SWLog has been continuously improved and expanded since it was first released in 1988. SWLog is a suite of products that provides logging, radio control, GPS synchronization, QSL management, reporting, and propagation prediction. Program schedules from HFCC, ILGRadio, AOKI, ADDX, SWSkeds, EiBi, and others are leveraged for broadcast reception. Call sign lookups and remote logbooks are integrated with ClubLog, eQSL, QRZ, Ham365, HamQTH, and LoTW. SWLog provides Android and iOS applications for logging on the go as well as web servers for logging and remote control from anywhere. SWLog works on Windows, Linux, iOS and Android

DXLook is a free, web-based propagation platform that delivers comprehensive, real-time insight into HF and VHF conditions directly from any modern browser. It aggregates live spots from PSK Reporter, WSPRnet, RBN, and DX Cluster, complemented by NOAA space-weather metrics such as SFI, K/A indices, and geomagnetic alerts. Integrated VOACAP predictions allow practical "theory versus reality" comparisons, while the interactive world map with filters, gray line, and grid overlays enhances situational awareness. With no installation or maintenance required, DXLook provides a convenient, accurate, and accessible solution for everyday operating and propagation analysis.
