Website dedicated to Coastal Radio Stations, includes frequency lists for memdium frequencies maritime stations

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
