This fourth e-book in the series on Amateur Radio HF Antennas covers essential, and often illunderstood HF antenna accessories. Lightning on the horizon? You are not worried … because you installed the lightning protection devices described in this e-book, and you have taken the preventive measures as prescribed. But that’s not all. Your HF antenna is now transmitting more RF power, and your receiver is getting more milliwatts from your antenna system, because you learned what types of antenna tuners to avoid. You are now using an efficient tuner, and you even know how it works. Your antenna tuner will likely have its own SWR/PWR meter. Notwithstanding, this e-book will help you decide if you still need an outboard one, and which meter will best meet your needs. Furthermore, armed with the valuable information you read here, you finally acquired the antenna analyzer to satisfy the expectations of the antenna experimenter in you. Emboldened by your recent successful acquisitions, you now have the antenna tower you were dreaming of. You heeded the recommendations this e-book provided and, thus, avoided all the pitfalls that await the unwary. Finally, an e-book series on HF antennas would not be complete without a word on HF signal propagation. It outlines the software and online services available today which enable you to take full advantage of band openings.

Spectrum Management for Science in the 21st Century

This book addresses the tension between the active services' demand for greater spectrum use and the passive users' need for quiet spectrum.

Radio observations of the cosmos are gathered by geoscientists using complex earth-orbiting satellites and ground-based equipment, and by radio astronomers using large ground-based radio telescopes. Signals from natural radio emissions are extremely weak, and the equipment used to measure them is becoming ever-more sophisticated and sensitive. The radio spectrum is also being used by radiating, or "active," services, ranging from aircraft radars to rapidly expanding consumer services such as cellular telephones and wireless internet. These valuable active services transmit radio waves and thereby potentially interfere with the receive-only, or "passive," scientific services. Transmitters for the active services create an artificial "electronic fog" which can cause confusion, and, in severe cases, totally blinds the passive receivers. Both the active and the passive services are increasing their use of the spectrum, and so the potential for interference, already strong, is also increasing. This book addresses the tension between the active services' demand for greater spectrum use and the passive users' need for quiet spectrum. The included recommendations provide a pathway for putting in place the regulatory mechanisms and associated supporting research activities necessary to meet the demands of both users.

Chasing RFI Waves

For this book edition in 2019, I went through everything once again, re-organized the text once more and laid it all out in book format. I want to state once more that the story is incomplete and I don’t know if I’ll ever finish it.

Back in 2005, I started writing what I’d planned to be a non-fiction book about NRAO (the National Radio Astronomy Observatory), based on visits, photos and interviews to this interesting place. My contact was Wesley Sizemore, NRAO’s public face and “Keeper of the Quiet”, a term which will make more sense to you once you read more about NRAO and the NRQZ (the National Radio Quiet Zone). I didn’t get to finish the book. Life intervened, I got caught up in other things and my photos, interviews and written pages (there are quite a few of them) sat in my Documents folder, gathering digital dust for about seven years. Rather than let it all sit there till oblivion, I thought it’d do more good published, unfinished as it is, so in 2012, I went through what I had, re-organized it, re-wrote some sections, re-edited some of the photos, and published it on my website in seven instalments. For this book edition in 2019, I went through everything once again, re-organized the text once more and laid it all out in book format. I want to state once more that the story is incomplete and I don’t know if I’ll ever finish it. Some sections aren’t filled in properly. As I wrote them, I had more questions that would get clarification only during subsequent visits, which never materialized. So please forgive whatever rough edges you find, including my barely adequate photos, since I was also at the start of my photographic career at the time. If I ever get the chance to make subsequent visits and finish writing the whole story, great. If not, here is what I have, for your enjoyment. It is worth reading. More people should know about the work being done by the NRAO: it is a neat place doing interesting research into things that have always obsessed humans: outer space, planets and aliens!

Newnes Linear IC Pocket Book is aimed at all engineers, technicians, students and experimenters who can build a design directly from a circuit diagram. In a highly concise form Ray Marston presents a huge compendium of circuits that can be built as they appear, adapted or used as building blocks. The devices used have been carefully chosen for their ease of availability and reasonable price. The selection of devices has been thoroughly reviewed for the second edition, which contains approximately 350 new diagrams. Marston deals mainly with strictly-linear ICs such as op-amps, pre-amplifiers, power amplifiers, signal-conditioners and power supply regulators, as well as various hybrid types: the 555 timer IC, bar-graph display drivers, CCD delay lines, function or wave form generators, phase-locked loops and power control ICs. The subjects are treated in an easy-to-read, highly practical manner with a minimum of mathematics. Ray Marston has proved, through hundreds of circuits articles and books, that he is one of the world's leading circuit designers and writers. He has written extensively for Electronics World, Nuts and Bolts, Electronics and Beyond, Popular Electronics, Electronics Now, Electronics Today International, and Electronics Australia, amongst others. All parts readily available from major suppliers. Packed with ready-to-build circuit designs. Handy reference for hobbyists, students and circuit designers.

In 1996, enforcement of the mandatory European Union EMI/EMC (electromagnetic interference and compatibility) began. Before that time, many designers were just beginning to worry about "EMI problems". Now, 8 years later, the same old EMI problems are still with us, and some new ones have emerged as well. Anyone selling components or equipment of any sort in Europe and therefore the world for most globally based companies requires compliance with the EMC directive. There is no alternative. The information in this book enables faster, cheaper compliance.
