PROPAGATION
For Radio Amateurs

Introduction to High Frequency (HF) Propagation
High Frequency (HF) propagation is a fascinating field that deals with how radio waves travel through the Earth’s atmosphere. Understanding HF propagation is essential for amateur radio operators as it enables them to communicate over long distances, sometimes across continents. Factors such as solar activity, atmospheric conditions, and time of day play crucial roles in determining how effectively radio signals propagate in the HF bands. By mastering the principles of HF propagation, radio enthusiasts can enhance their communication abilities and make the most out of their hobby.
