o you have a radio and an antenna, plus all of the other fancy devices imaginable to enable transmit and/or receive signals. But, all of this top-of-the-line radio gear notwithstanding; you wonder why the radio-wave signals behave in such an “unpredictable” manner and you lose contact, or it fades or varies up and down like a roller coaster causing frustration. That’s radio wave propagation!

If you don’t have a reasonable knowledge of the behavior of propagation, your knowledge of radio is missing a huge and important ingredient and you are not enjoying this activity to its fullest. Instead of just turning off your rig because of frustration, learn how propagation can work for you and not against. Even if you think your regular schedules are doing just fine, maybe they could be better than you realize if only you knew more about this natural phenomenon.

This is why we offer this new and fresh approach to learning about this important subject now contained in this series of books, Radio Wave Propagation by M.H. De Canck, ON5AU of Belgium. Volumes 1, 2 & 3 are available to be followed by more volumes. The author’s unique presentation on the subject is not only interesting, but actually makes it a fun learning process — not often said about this complex subject! Part of the secret to making it fun is the unique animation Wizards that can set the propagation into motion to show the signal flow around the globe. Now, you can see it and not have to just try to imagine it — if you can, accurately.

This is not just another traditional set of books about radio wave propagation. Radio Wave Propagation a series of books about propagation in all its aspects. Propagation is too complex and multilateral to be fully explained in just one book. So, why another book about this subject? There are several good ones on the market already. From the start it was the intention of the author to explain also the questions raised as “ WHY? WHERE? HOW? WHEN? Questions he raised very often when reading and studying Radio Wave Propagation from the myriad books, magazine articles and manuscripts. The goal was from the beginning, to look beyond the comprehension's of the various propagation and ionospheric properties. The goal was also to explain things in a clear and logical manner to everyone wanting to learn, especially for the whole of the radio community—from the beginner to the advanced.

As most know, illustrations of any kind (sketches, graphs, diagrams, etc.), explain and convey thoughts and ideas much better than just plain text alone. But, animated graphs and diagrams can even better express certain behaviors and phenomena associated with a moving, changing environment surrounding propagation. In this original series of books is the birth of the Presentation Form WIZARD as a teaching tool for this subject.

These books rovide some bonus study aids, such as: an extra companion 129-page study book with more than 240 illustrations—a book in its own right, thus two books for the price of one. Then again, included in each volume are the unique WIZARDS presenting various informative animations to help the reader visualize the propagation properties explained in the Chapters instead of having to, at best, imagine the movements of the propagation phenomenon. Thus, the reader understands and learns faster by "seeing" the signals move across the globe toward its destination.

You will be very pleased with these fresh new books on propagation and surprised about the information presented and amazing learning devices not found in other propagation books on the market, making good use of the new electronic media technology not available a few short years ago.

What you get in Volume 3:

Sporadic-E is still a mysterious phenomenon in spite of the continuous research and today's high-tech support. This sporadic phenomenon is best known and appreciated among the VHF DX communicators. Only few are aware that sporadic-E is not so sporadic as first thought, but in fact a rather daily event influencing our HF communications in various ways. Sometimes helpful, sometimes harmful. This statement of daily Sporadic-E occurrences is often a source of discussions at club meetings and often disagreed by the VHF DXers but confirmed by mainly HF bands communications Radio Hams.

Fact is, when consulting the hourly ionograms of various worldwide spread ionosonde stations, you find practically daily Sporadic-E registrations or traces at the ionograms. These are well distinguishable from the normal E-layer ionization plots or the numerical values. Also, when analyzing and evaluating my daily real-time monitored NCDXF/IARU beacons, I had to conclude that only when there was “help” of Sporadic-E, a certain beacon could be received where it should not when Sporadic-E was absent.

There is also a great confusion about the highest supporting MUF-Es in special. When sporadic-E supports VHF 2 meters band communication, we have to consider the wave propagation happens by patch to patch refractions within the Es cloud itself and therefore increasing the experienced MUF-Es significantly. There is a remarkable difference between the experienced MUF-ES and the conventional MUF-ES computed as foEs * MUFF-Es. The latter would never reach 144 MHz.

This Volume 3 of the Radio Wave Propagation series will unveil these matters and visualize it by real-time monitoring. The traditional extra WIZARDS will give you an animated pictures of this Sporadic-E phenomenon.

What you get in Volume 4:

What are the proper procedures essential to calculating reliable radio signal propagation predictions? These questions are fully explained in this Volume 4, which is a sort of VOACAP manual or cookbook. It will unveil many hidden possibilities such as interacting in the GUI (Graphic User Interface) and the syntax to use when encroaching the program flow. Of course the correct input parameters must be declared in the various input fields and some of them have more impact to the output results then others. Great pain is taken to explain such important factors. A fact is that many programs use VOACAP as engine but does not always employ all the useful options available by this engine. In this Volume 4, we study and explore all the options VOACAP offers.

One such important input data is the antenna choice, but not only that. Not correctly beaming the antenna toward the target location can also result to sometimes absolutely unrealistic output results. That is often the reason why some disappointed prediction program users conclude: “These programs are useless or incorrect.” Also, the program's installed default settings are not necessarily suitable to HF ham band use. Instead they are the settings for broadcast HF transmitters using AM (Amplitude Modulation) and very high power to reach even portable shortwave receivers with a whip antenna. Altering a program's settings for specific band needs are discussed.

Further, predictions are often a great help to contesters and DX chasers. This unique VOACAP manual should lend greatly to help to do it efficiently and with adequate knowledge to minimize mistakes and disappointments. Recently, the author computed predictions for the UBA (the Royal National Society of Belgian radio amateurs) candlelight test, spread over the winter month (communications via QRSS mode with extreme low power transmitters, less then 1 watt, where some of them were more then 8 000 km – 5 000 miles distance away). These predictions did show when these low power station should or could be best received to the joy of the UBA.
