Deciphering a Propagation Report
Richard VE2XIP has an informative blog on a variety of Amateur Radio subjects. Among the areas he covers is a very good primer on HF Propagation. I know this subject can be a difficult one to grasp, especially for beginners—even the more experienced have challenges in this area.
“The very first thing I noticed when I got interested in propagation was a vast number of websites displaying charts and grids related to HF propagation conditions, but I didn’t really understand them at first. There are more types of measurements about the Sun’s activities than most care to understand, but there are a few ones that are very important to learn if you want to be able to understand a propagation reports.”
