From our propagation columnist, Tomas, NW7US: Are you interested in learning about the Sun, space weather, including topics of sunspots, solar flares, coronal mass ejections, as well as topics on the ionosphere, the magnetosphere, and how radio waves propagate from transmitter to receiver? Heres a time-proven course that you can self-study, so that you can become well-versed in this information. Normally, the course is USD $200. With the ray-tracing PropLab PRO software, it is normally bundled for $275. Effective now, though, were offering it to you on sale. The course itself is $100, while the bundle is $175.
