Free Radio Wave Propagation Course

Eric Horwitz, KA1NCF writes on the North Shore RA mailing list:

Here is a good refresher (perhaps better to have been sent BEFORE Field Day) for the club membership (some of who are not DXers).  This came from the FEMA Urban Search & Rescue Comm group that I’m on and was sent for widest dissemination.  Please forward to the club as a whole, to include the FD distro list, and anyone else you think appropriate.  Thanks.


Greetings,

The COMET Program is pleased to announce the publication of the new lesson, “Radio Wave Propagation“. As a society we have become dependent on satellite communications, but satellites fail with alarming frequency. Before the advent of satellites, long distance communications were carried out with high frequency (HF) radio transmissions. This 1-hour lesson examines the factors that control long-distance radio communications, with an emphasis on refraction in the ionosphere, frequency selection, and the effects of solar radiation.

The intended audience for Radio Wave Propagation is any potential radio operator who communicates across long distances using HF frequencies. This can include members of the U.S. DoD, emergency management, and amateur radio operators.

We welcome any comments or questions you may have regarding the content, instructional approach, or use of this lesson. Please e-mail your comments or questions to Alan Bol (alanbol AT ucar.edu). For technical support, please visit our Registration and Support FAQs .
