Getting Started in EME
Bouncing signals off the moon has always been considered as one of the most difficult of the amateur radio disciplines. Traditionally, Moonbounce (as it's known) was practiced by amateurs who are the most accomplished engineers, as well as operators—but recent developments have now made it more accessible than ever before. "Getting Started in EME" sets out to explain what you need to know and how to get started in this captivating area of amateur radio operation. This 64-page paperback sets out the history of Moonbounce, gives information on the various EME bands, and the reasons for choosing them—and then explains the EME signal path. It covers the unique propagation effects, such as libration fading, Faraday rotation, and spatial offset. Ground gain, Doppler shift, and degradation are also covered. The book is practically based and focuses on EME at 144MHz (2m) and proposes, wherever possible, the use of equipment that is already owned in order to reduce the cost of getting started in EME. This is particularly the case with antennas, but you'll also find coverage of transceivers, pre-amplifiers and power amplifiers. Again, the emphasis is on the minimum possible requirement, utilizing equipment that may already be in the shack. There is coverage of computers/interfaces, software and operation requirements, and even your first EME contact! EME at 70cm is covered, and there are glimpses where the newcomer to EME might move onto when they find themselves bitten by the Moonbounce bug. If you've never tried EME transmissions or are just interested in what it takes to make that first contact via bouncing a signal off the moon, then "Getting Started in EME" is the ideal introduction.

Amateur Radio Mobile Handbook
The fascination of taking a radio away from home and making contact with stations both near and far is an enduring one in amateur radio circles. Written by acknowledged mobile expert Peter Dodd, G3LDO, "Amateur Radio Mobile Handbook" is for those who regularly "go mobile" or simply want to start doing so. Mobile operation can offer a great escape from EMC problems or restricted home operation—and provide the challenge of the quest for that really good operating location. The 128-page paperback covers all aspects of this popular part of the hobby. From the basics of amateur radio mobile, installing radio equipment and antennas in a vehicle, maritime mobile, and bicycle mobile to pedestrian mobile, you'll find it all covered here. In addition, "Amateur Radio Mobile Handbook" contains a chapter on antenna measuring equipment and how to use it. You'll even find the use of kite- or balloon-supported antennas and the experimenting with unconventional antenna arrangements described. There are also guides to the possibilities of APRS and D-Star operation. In spite of a greater use of electronics and the lack of space in modern vehicles, the availability of lightweight, comprehensive radios means that it has never been easier to become a mobile operator. The "Amateur Radio Mobile Handbook" provides essential reading for all those who want to get the most out of amateur radio mobile.

Building a Transceiver
Home construction is alive and well among the ranks of today's radio amateurs—and "Building a Transceiver" brings to life how making something as complex as an HF transceiver can be achieved with very simple equipment and techniques. One of the benefits of building your own transceiver is that you'll understand how it works; and then you should be able to fix it or improve it in the future. This 176-page paperback is based on the relatively complicated HF transceiver project that's been broken down into smaller modules which can be built and tested individually. Each module is described in cookbook fashion so that the constructor understands how it works before starting the build. The constructor may choose to build a complete transceiver based closely on this design, add in some of your own modules—or you may prefer to mix and match by using parts of this design and integrating them into a completely different project. This modular approach means that you could, for example, take the VFO design and adapt it for use as a signal source in test equipment. "Building a Transceiver" is based on the hugely popular 'Homebrew' column in RadCom written by Eamon Skelton, EI9GQ. Readers will find that the book covers the detailed electronic design process and practical constructional techniques necessary to build the transceiver. Most modules are in the dead-bug construction style, and this is fully detailed—along with a number of other useful techniques. Photographs are also provided to help the reader visualize the final layout of each section. Each element of the transceiver is described fully with details of components and any board layouts available. You may never build the complete transceiver described in this book, but the construction techniques and testing has been designed with the resources of an amateur radio shack in mind, so it will be useful no matter your level of experience and whatever you decide to build.

SOTA Explained
Summits on the Air (SOTA), is one of fastest developing award schemes that have come into existence in recent years. For the active hillwalker and the home-based chaser of summits alike, this program offers endless fascination. "SOTA Explained" provides the essential guide to this program, hilltop radio, and much more. Taking a portable radio station into the hills and operating from a summit is a fascinating and rewarding way to combine the very best aspects of walking and of amateur radio. SOTA activity is also inexpensive, providing the opportunity to achieve a great deal in amateur radio. Many appreciate the freedom this sort of operation offers and the benefits of having a high radio station far from urban electrical interference. At altitude, even modest sets can deliver astonishing performance: communication across the country and across the continent is routinely available—and on many days, mountain-to-mountain conversations flow across the world. This 160-page paperback also provides advice for those who do not venture onto the hills but still want to participate in SOTA. There's a whole chapter dedicated to chasers—from the bands to choose, how propagation affects your operation, chasing DX stations, and rare SOTA activations. Not only does "SOTA Explained" detail how SOTA works, but there's advice on safe hillwalking, setting up simple and cheap SOTA stations, and modes of operation. You'll read technical advice on improving your first station, the antennas to choose, and how to run SOTA stations on HF. The book isn't just for those new to SOTA; the more experienced operator will find much of use, too. Be warned: after reading this book, you will never see a hilltop in the same way again.
