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.
