Here to There: Radio Wave Propagation Tools You Can Use for the Current Solar Cycle

Propagation Know-How Amateur radio communication depends upon the movement of radio waves, and hams spend a lot of time designing a station that will send those waves in a desired direction. As soon as your transmission leaves your antenna, however, it is subject to the often-misunderstood effects of propagation.. Here to There: Radio Wave Propagation presents the principles of signal propagation in an easy-to-understand style. It provides practical advice on understanding whats going on in the ionosphere and troposphere, how takeoff angle impacts your transmission, how far you can really communicate over VHF and UHF, and much more. Knowing ionospheric structures, how they form, and which bands they interact with will prepare you for practical operating and help you make the most of your time on the air. Fundamentals of Radio Wave Propagation A breakdown of the science underpinning your communications. The Sun and Solar Activity Understand how the Sun interacts with the ionosphere and what that means for your transmissions. Sky-Wave, or Ionospheric, Propagation How radio waves, primarily at HF and below, travel through the ionosphere. VHF and UHF Non-ionospheric Propagation Ways in which VHF, UHF, and microwave propagation defies line-of-sight limits. Propagation Predictions for HF Operation Programs and tools available to assess and plan for propagation in the HF spectrum. VHF and UHF Mobile Propagation Whether in a car or at your home station, learn about the terrain and atmospheric effects impacting your transmissions. Amateur Radio and Ionospheric Science Ionospheric science uses ham radio observations and data sets. Learn about Traveling Ionospheric Disturbances, eclipses, and other unusual phenomena, and how you can participate in citizen science!
