Ward Silver N0AX writes In Nuts and Volts magazine about the Solar
Eclipse and Amateur Radio

I hope you have Monday, August 21st circled on your calendars in
bright red ink. A total solar eclipse will be seen on that day by
millions of people from Portland, OR to Charleston, SC. Many more
millions will see a partial eclipse.

The optical effects of an eclipse are relatively obvious and
well-understood. Partial solar eclipses are fairly common and lunar
eclipses even more common. Not many of us have witnessed totality, but
most people have seen some type of eclipse. What very few people have
observed is the effect an eclipse has on radio propagation.
