Understanding LF and HF Propagation ebook


In 2008/2009 Alan Melia G3NYK and I wrote a series of features on understanding LF and HF propagation for the Radio Society of Great Britain's (RSGB) "RadCom" magazine.

My features consisted of a month-by-month look at each HF band in turn, showing the reader the propagation modes behind each band and explaining some of the technicalities of ionospheric propagation.

I looked at the D, E and F layers, Sporadic E, the MUF/LUF, using solar data, propagation programs, NVIS and much more.

Alan then took over and wrote three detailed features on LF propagation. We are told that the features were well received and as a result I have managed to persuade the RSGB to allow me to put them together into a single document, which is now freely available for amateurs worldwide to download.

I hope you enjoy it.

    Nice one Steve! I gave it a plug on CQHQ blog.

    I have heard good things about your book Stealth Antennas from a couple of people too, so that one should sell well if the grapevine is anything to go by.

    Best of luck Steve GW7AAV

    Many thanks for the e-book. Its a good article/refresher. Its a pity more magazines dont go down the e-book route, as it would reduce the amount of paper I recycle each month.
