RTTY/PSK31 for Radio Amateurs By Roger Cooke, G3LDI Data modes appear to be a daunting prospect to newly licensed radio amateurs, but they do not have to be. This book is a practical guide to the two most popular data modes, RTTY and PSK31. RTTY is the oldest real Data mode and was first used on the amateur bands over 50 years ago. In those days it was a complex mode to use, with teleprinters and home made transmitters to modify. However, in the computer age, it is much easier to both use and set up. RTTY and PSK31 for Radio Amateurs provides you will all you need to know to get the most out of this fascinating area of amateur radio. Readers will find details of where to find data modes on the amateur bands, through getting started, to making the most from both these modes. DXpeditions and contests use these modes and there is lots of information on getting the best from these too. Free CD The free CD that accompanies this book provides an A-Z of amateur radio data mode programs to get you started. You will also find reviews of equipment, lots of reference material and web links, essential reading for anybody interested in Data. RTTY and PSK31 for Radio Amateurs does though carry a warning: Buying this book may lead to an enjoyment of RTTY, PSK31 and Data modes in general that is highly addictive.

SOE: The Scientific Secrets By Fredric Boyce and Douglas Everett The history of Special Operations Executive (SOE) seems to spring a never-ending run of surprises, and here are some more. This book explores the mysterious world of the tools SOE used for their missions of subversion and sabotage. Written by a scientist who served in SOE and an engineer who shared the task of clearing up after it was disbanded, their insider knowledge provides a clear account of the way in which SOE inventors worked. The often grim reality is confronted and is more akin with the world of James Bond and Q’s workshop was than previously believed. From high explosive technology to chemical and biological devices it is all here. Readers will find details of clandestine radios used alongside the techniques of air supply, camouflage, underwater warfare, weaponry and so much more. SOE -The Scientific Secrets is a revelation about the tools that allowed the murky world of spying and spies to operate during wartime. A thoroughly recommended read for anyone interested in these WWII activities. Size 164x239mm, 336 pages ISBN 9780 7524 5329 3 Post Free for RSGB DD Payers Price: £8.49

ENIGMA U-BOATS: Breaking the Code By Jak P Mallmann Showell Revised updated and made available for the first time as a paperback book ENIGMA U-BOATS: Breaking the Code is the true story of the Enigma machines taken from U-Boats in WW2. ENIGMA U-BOATS: Breaking the Code is written by the acknowledged expert on the history of the U-boat arm in the Second World War. This book analyses the development of Enigma, following the story from the shocked German admirals who discovered that the Royal Navy had penetrated their secret radio codes during WW1. The response of the German navy to make a coding system, so complex that breaking their codes, would be theoretically impossible - the Enigma machine. There are details of the development of Enigma, its role during German U-boat operations, and the subsequent code-breaking work at Bletchley Park. This book examines in detail all the U-boats known to have been boarded by the Allies during the war from which Enigma machines could have been captured.

25 Years of Hart Reviews by Peter Hart, G3SJX 25 years of Hart Reviews is a collection of every single review Peter Hart, G3SJX has published in RadCom from 1979-2004. RadCom's leading equipment reviewer has covered some of the most significant changes to radio technology in the last 25 years. Peter has covered the first amateur radio equipment to include microcontrollers which, in turn, made possible the single tuning knob digital frequency synthesiser and the ability to make stable oscillators at VHF. This made viable the up-conversion broadband superhet architecture which forms the basis of virtually all successive designs up until the present day. Nearly 100 equipment reviews are included in this book and cover every conceivable type of transceiver, including a variety of antennas and amplifiers as well. This book is not only a fascinating view of 25 years of amateur radio equipment but is a valuable guide to the new and second hand buyer of equipment. RSGB, paperback, 210 by 297 mm, 264 pages.
