By 1939, Josef Goebbels had won the struggle for control of the propaganda process in Nazi Germany. In contrast, it took the arrival of Sefton Delmer in 1941 for anyone in Britain to understand how to use propaganda to subvert the German war effort. Through the shadowy Political Warfare Executive, the ‘black’ radio stations Delmer created lured German listeners with jazz and pornography (both banned), mixed with subversive rumours. Millions of ‘black’ leaflets – perfect forgeries of German documents, with subtly altered texts – were produced, their aim to encourage malingering, desertion and sabotage.Black Propaganda looks at the variety of propaganda used in the Second World War and explains how British and Polish intelligence worked together on a number of key security issues, including the ‘Enigma’ machine and the German V-weapons programme.

Amsats and Hamsats provides a step by step guide to how you can communicate through amateur radio satellites and how to receive signals from other small satellites and 'weather' satellites. The book gets right into the techniques you will need for working amateur radio stations through amateur radio satellites, then moves on to listening, or watching, signals from other satellites. There are chapters answering questions like, 'how do satellites stay in orbit' and 'why are they so expensive to launch?' Followed by sections about the history of amateur radio satellites, the mathematics governing orbits, TLE files, different types of satellite and their orbits. It covers the equipment you need, to track and use the amateur satellites and some of the satellite tracking software that is available. There are detailed sections covering transponders, satellite bands, feeders, masthead preamplifiers, antenna systems and automated rotator control. Plus chapters on the FUNcube Satellites, Weather Satellites and even the International Space Station. Amsats and Hamsats provides the ultimate guide to operating satellites and how they work. Its 368 pages are a great value guide to this stimulating and challenging area of amateur radio activity. Whether you want to get started or you are already an experienced operator you will find something of value in these pages.

This book includes useful tips and tricks for the configuration and operation of the amazing Yaesu FTDX101D and FTDX101MP transceivers. Rather than duplicate the manuals which describe each button, function, and control individually, I have used a more functional approach. This is a "how to do it" book with easy to follow, step-by-step instructions. For example, I describe how to set up the transceiver for SSB operation. Then I follow that up for CW, FM, RTTY, PSK, and external digital mode software such as FT8. The aim is not to replace the manual but to more fully explain how to configure and operate the radio to take advantage of its many great features. For example, when I cover the front panel controls, I explain not only what the control does, but how and when to use it. Along the way, I offer a few 'tips' on how I configured my radio. You don't have to follow these suggestions, but they provide some guidance.The FTDX101 transceivers have superb technical specifications, and the FTDX101D currently holds the top position on the highly regarded Sherwood Engineering transceiver performance table. The book covers both variants of the transceiver. The FTDX101 is a truly exceptional radio for contesting or working DX stations. Learn about the dual receivers, the band scope display, and the new FT8 Preset. This book will help you get the most from this complicated transceiver.
