Radio Today Guide to the ICOM IC-9700
"The Radio Today Guide to the ICOM IC-9700" is the third in this series of books aimed at getting the most out of your radio. It's written in the same style as the other books, a practical guide to enjoy the full flavor of possibilities with the groundbreaking IC-9700. The radio is the first full power, multi-mode, VHF/UHF amateur radio transceiver to be based on SDR technology. It's a transceiver for VHF and UHF DX operation, working satellites, EME, and repeater operation, supporting both traditional FM repeaters and D-Star digital. Author Andrew Barron, ZL3DW, an acknowledged SDR expert, highlights the myriad options available to ICOM users—many of which have never been available on VHF/UHF transceivers before. As usual, this book does not duplicate the manuals which describe each button, function, and control; it's a "how to do it" book with easy-to-follow step-by-step instructions. All of the great new features included in the IC-9700 can make it quite a complicated radio to configure and operate, but this 160-page paperback covers every control and menu setting and explains how to get the most from this truly remarkable radio.

The Low Power SPRAT Book
QRP—the art and science of low-power operation—is one of the most popular aspects of amateur radio. In the UK, the G QRP Club has been a leading light in this area of operation since its formation in 1974. Its journal, SPRAT, is recognized as one of the world's leading QRP publications and it has now reached its 150th edition. The milestone is marked by publication of this book, a selection of the best of nearly four decades of low-power amateur radio circuits and ideas that have been published in SPRAT. "The Low Power SPRAT Book" is divided into seven parts, covering transmitters, receivers, transceivers, antennas, ATUs, Morse keys and keyers—and a section for those circuits that do not fall happily into any particular part, but which might best be categorized as 'miscellaneous.' Circuits vary in complexity from an ultra-simple 80m CW transceiver using just 14 parts … to the more sophisticated Sparkford, designed by Walford Electronics and also for use on 80m CW. You'll find early classics within these pages, including the OXO transmitter from 1981 and the ONER dating from 1985/1986, both GM3OXX designs. This 320-page paperback also includes QRP classics, such as versions of the FOXX transceiver, the Pixie in its various guises, the Epiphyte and the Naxos. All are presented exactly as they were originally printed. This book will appeal to anyone from dedicated QRP enthusiasts, to those who've never tried QRP construction work before. It's a veritable gold mine of ingenious designs and circuits, providing a superb introduction and reference book dedicated to the art and science of low-power or QRP amateur radio.

Portable Antennas for Everyone
Portable operating has never been as popular as it is today, thanks to the many excellent modern, small, and lightweight transceivers that are available. But indoors or outside, any station is only as good as its antenna, and that's where this book comes in. "Portable Antennas for Everyone" is broken into sections covering the main types of antenna. Specific designs from around the world are included, starting with a fiberglass pole and a simple 10m length of wire attached to make a quarter-wave vertical antenna for 7MHz. The 192-page paperback continues into verticals designed specifically for use by the ocean and that provide a super-low angle of radiation of just 6 or 7 degrees above the horizon. This book describes how to make a vertical dipole array (VDA), and there's some good advice on kite-supported verticals. You'll also see designs for HF dipoles, doublets, and making your own lightweight HF beams. VHF and UHF antennas are not forgotten: the book includes a dual-band Yagi for satellite working, collapsible 2m and 6m beams, a roll-up J-pole, a 70cm Lindenblad antenna, and even a dual-band beam made from tape measures. Read reviews of commercially made antennas for portable operations—such as the Spiderbeam, the ultra-lightweight Hexbeam, the folding Hexbeam, the all-band SuperStick, an easily transportable magnetic loop, and much, much more. If you're suffering from high domestic noise levels at home, operating portable from the countryside can be a real revelation. Often there is no local noise whatsoever and you find you can copy S1 signals with ease. So now there's no excuse: "Portable Antennas for Everyone" allows everyone to get on the air while experiencing the great outdoors!

Microcontroller Know How
Microcontrollers are used today in a wide array of applications—car engine control systems, implantable medical devices, remote controls, office machines, household appliances, toys, and much more. The technology has never been more accessible to the amateur, and this book sets out to show, in an easy-to-understand style, how to make these powerful tools work for you. "Microcontroller Know-How: Amateur Radio Projects and Much More" introduces you to the controller types included and provides practical working microcontroller projects for these with all the supporting files. The projects range in complexity and are aimed at different microcontrollers to take the reader on a learning journey in embedded software development using 'C'—while also providing exposure to different technologies and development environments. Projects are targeted at the STMicroelectronics STM32 processor range, the Amtel/Microchip ARM processor range, and a Wi-Fi connected project using the 'Internet of things' Espressif Systems ESP8266 microcontroller. An introduction to PIC programming in 'C' is also included with a set of basic projects targeted at the PIC16F18877 device. For the wide variety of projects included you'll find details on the development environment, build instructions, and source code—alongside illustrative pictures and diagrams to ensure the reader can recreate a working example. The author has built and documented each project and all the source code and other supporting files are also available online. If you want a straight-forward guide to microcontrollers that gives you the confidence to tackle projects on a variety of different technologies, or want interesting projects to try, or perhaps just an insight into this topic, then this 160-page paperback is certainly the book for you.

LF Today
Low-frequency operating has never been more popular, and the introduction of a new international amateur allocation at 472kHz means that, with 136kHz, there are now two bands below 1MHz. "LF Today" distils nearly 20 years experience of the low frequencies and aims to help you get the most out of operating in this part of the spectrum. This third edition of "LF Today" provides the reader with a firm knowledge of the frequencies below 1MHz—and has been expanded to include the many revisions and updates. New to this edition are many projects for the 472kHz band, an analysis of the various modes used on the low frequencies, and how to receive and transmit on even lower frequencies at VLF. A guest chapter by Alan Melia, G3NYK, explains how to predict LF ionospheric conditions. This 192-page paperback includes practical information on antennas, receivers, transmitters, and operating. Written by one of the leading authorities on LF, Mike Dennison, G3XDV the book will help beginners who want to try out this fascinating amateur allocation—but it's also of great value to anyone already active on the band who wants to expand the knowledge of the bands. In short, "LF Today" is a one-stop shop for anyone seeking information on amateur radio operation below 1MHz.
