On August 21, a total solar eclipse will cause the shadow of the moon to traverse the US from Oregon to South Carolina in just over 90 minutes. Radio amateurs are preparing to participate in one of the largest ionospheric experiments ever performed by making radio contacts and looking for signals throughout the eclipse. How much do you know about the ionosphere and radio wave propagation?
Order Propagation and Radio Science, by Eric P. Nichols, KL7AJ, for some insights. It presents a comprehensive overview of radio propagation in simple, easy-to-understand terms and graphics. This book explains the invisible phenomena we observe on the air and invites you to embark on the journey of radio waves from transmitter to receiver, and through the voids of space!
