Low-power operation or QRP is one of the most popular aspects of amateur radio and the UK's G-QRP Club is a leading light in this area. This book draws together the very best articles from authors around the world that have been published in the club's journal Sprat in recent years. Packed with projects QRP Scrapbook contains all-new material not previously published in an Radio Society of Great Britain (RSGB) book.
There is much included in this book and there are modern techniques including a practical RF generation system for superhets using direct digital synthesis (DDS) modules, the use of TV 'dongles' to make a software defined radio (SDR), plus Arduino microcontroller projects for a CW transceiver and keyer and much more.
The QRP Scrapbook has six sections covering QRP transmitters and transceivers; simple and also somewhat more complex receivers; antenna systems and test equipment suitable for low-power operation, and a 'miscellaneous' section covering subjects as diverse as how to wind toroids tidily, making your own ribbon cable, Morse keys and keyers, crystal oscillators and ceramic resonators. With the increasing problem of local interference, the noise cancelling device in this section will be of interest to all amateurs, not just those who operate with low power.
Produced in co-operation between the RSGB and the G-QRP Club, QRP Scrapbook is essential reading for all interested in the latest in home-construction techniques and the art and science of low-power amateur radio.
