Portable Antennas for Everyone Portable Antennas for Everyone
50 Antennas covering 80m-70cm

Edited by Steve Telenius-Lowe, PJ4DX


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 is 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 fibreglass pole and a simple 10m length of wire attached to make a quarter-wave vertical antenna for 7MHz. Portable Antennas for Everyone 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. The book describes how to make a vertical dipole array (VDA) and there is some good advice on kite-supported verticals. There are also 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. You will also find reviews of commercially made antennas for portable operations. These include the Spiderbeam, the ultra-lightweight Hexbeam, the folding Hexbeam, the all-band ‘SuperStick’, an easily transportable magnetic loop and much, much more.

If you are 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!

Transmission Lines Explained Transmission Lines Explained
Feeders, Waves, Stubs and a whole lot more for Radio Amateurs

By Mike Parkin, G0JMI


Getting the signal from your radio to the antenna is a vital component of any radio setup but few understand the full impact their feeder is having. This is where Transmission Lines Explained steps in. It provides the theory involved, through descriptions and techniques rather than mathematics.

This book provides an understanding of the theory, operation and use of transmission lines. It examines where twin-line cable or coaxial cables are used, not only as antenna feeder cables, but also as a basis for the matching arrangement between a line and its load. Broken down into logical sections, Transmission Lines Explained includes examples of how transmission lines can be constructed to suit particular applications. Techniques are included that summarise how coaxial cables can be fitted with connectors, including BNC, N and PL259 types. There is a section covering the use of the Smith Chart, where the effect of a mismatched load on a transmission line is described, including several practical examples. There are, of course, mathematical explanations of given situations, where necessary. Explanations of the coefficients associated with transmission lines are provided. This sets the scene to describe how a mismatch between the transmission line and its terminating load results in a reduced power transfer and its consequence, a standing wave pattern. Details are provided covering how different impedances can be matched using sections of transmission line, common mode currents, their effect and how they can be minimised using baluns.

Transmission Lines Explained is the ideal compilation of techniques, descriptions and examples so that radio amateurs can gain an understanding of the concepts associated with transmission lines.

Roger So Far.... Roger So Far....
The first 100 years of the Royal Corps of Signals


Since its formation in 1920, the Royal Corps of Signals has provided the British Army’s central nervous system. Roger So Far... is a celebration of the Corps’ achievements and the ability of its soldiers to use innovation and improvisation to deliver results beyond all reasonable expectations. This large format hardback book is lavishly illustrated in colour and provides an insight like no other into the activities of Corps.

Communications are a vital part of the Army’s fighting power and the Corps has been crucial in supporting the vast majority of military land-based operations following the First World War. Only with clear and trusted communications can commanders support, control, and lead their units and soldiers. The evolution of electrical communications in the last 150 years has been one of the most important developments humanity has ever witnessed. Its importance is growing because conducting successful operations is becoming increasingly reliant upon being able to operate in a congested and contested electronic battlespace.

Roger So Far... acts as an historical record, covering the 100 years of operations that the Corps has been involved in, including such diverse conflicts as WW2, Suez and Afghanistan. There are many reminiscences covering aspects of life within the Corps during its first 100 years. It seeks to stir memories and to inform those who are serving, or have served in the Corps, as well as to inform those who have not served.

The Secret History of Signals Intelligence in the World Wars

By Peter Matthews


This great and extremely popular book is now available as a paperback. Signals Intelligence, or SIGINT, is the interception and evaluation of coded enemy messages. Written by acknowledged expert Peter Mathews this book reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers.

From ENIGMA to ULTRA, PURPLE to LORENZ, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during both the First and Second World War. During the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to, code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty's famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. SIGINT even provides a fascinating account of what Allied investigators learned post war about the Nazi equivalent of Bletchley Park.

Including material from declassified NSA documents, SIGINT provides an insight into the work of this shadowy organisation and its achievements. If you are interested in Enigma, Bletchley or the work of Room 40 this book is recommended reading

Radio War Radio War
The Secret Espionage War of the Radio Security Service 1938-1946

By David Abrutat


If you have every wondered what Radio Amateurs did during WW2, then this new hardback book will be a revelation. Many books have described the work of Bletchley Park and even the work of GCHQ and SIGNIT but Radio War extends this into the work carried out by that voluntary interceptors (VI) many of whom were radio amateurs and RSGB members. It does not stop there either as it describes the secret operations, the stations used and so much more.

During the Second World War German intelligence had deployed wireless teams throughout occupied Europe. Agents had even been deployed to mainland Britain to spy on British military activity. Monitoring and reporting of their wireless transmissions fell to a small, secretive and largely unknown unit manned almost exclusively by volunteers. The VIs would spend hours every day at home monitoring the short wavelengths for often faint and difficult to copy signals transmitted by these German secret intelligence services. This unit was to become known as the Radio Security Service (RSS) and was at the core of the signals intelligence production effort at Bletchley and the insights into German military tactical and strategic planning.

Without interceptors like the RSS, Bletchley would not have existed. Their story has never truly been written before but Radio War focuses on their secret world of wireless espionage. There is included an honour roll of RSS operatives which details their area of operation, callsigns, locations. Not surprising this list is packed with well-known radio amateurs of the day including at least one RSGB president. Patrick Reilly, the Assistant to Head of MI6 Stewart Menzies, was to say of the RSS `a team of brilliance unparalleled anywhere in the intelligence machine.'

This book is a truly exceptional insight into the activity of the RSS, radio amateurs in WW2 and much more. It is thoroughly recommended reading

Power Supplies Explained Power Supplies Explained
By Paul Lee, G3ZKO


A power supply is something that is often overlooked by radio amateurs, as for many it is simply the box, that at the flick of a switch, provides stable DC voltage. A modern power supply is though much more, combining theory that dates back to the nineteenth century incorporating the latest techniques in digital control, with a wealth of electronics practice in between. Power Supplies Explained sets out to do exactly this - explain in understandable terms what that little box is doing, right through to designing your own bespoke power supply.

Some believe there is a little magic in power supply design; beginners especially are wary of the challenging mixture of digital, analogue, magnetics and control loops, with cooling, EMC and safety to contend with as well. Whilst many books deal with the theory in depth, they often give little guidance on the practical aspects of achieving working designs - Power Supplies Explained is different. This book seeks to detail how circuits are chosen for the application and how circuits are designed including their inductors and transformers. Calculations are outlined in a simple way so that the reader can use them as a basis for their own designs.

Readers will find chapters that include descriptions of 'linear' supplies and a wide range of 'switched-mode' types from simple buck converters to the latest off-line high-efficiency topologies. The worked examples are based around typical radio amateur requirements and in many cases are versions of commercial products that the author has successfully designed. There are also chapters on magnetics theory, control loops, EMC, practical construction techniques, test equipment and much more. High voltage power supplies are included with comprehensive guidance on safety.

Power Supplies Explained sets out to dispel the mystery and encourage readers to 'have a go' with their own designs and get the satisfaction of being able to say, 'I made that'.

Fuelling the Wars Fuelling the Wars
PLUTO and the Secret Pipeline Network

By Tim Whittle


This hardback book is a fascinating insight into something entirely unknown to many, the UK's network of petroleum pipelines transport fuel from refineries and terminals to major airports, airfields, and distribution depots. The largest of which has its origins as far back as the Second World War and is one of the few remnants, still operational, of the vast infrastructure that was built to fight that war.

In 1936 the RAF had total fuel reserves that amounted to just 8,000 tons. With a potential war in sight a programme for the construction of protected storage depots was started with the first of these coming on-line in 1939. In total the Air Ministry constructed 78 new storage depots with a total capacity of over 1.6 million tons. Possibly the best-known part of the network are the PLUTO cross channel pipelines. However, they were not as successful as popularly imagined, and the battle of Normandy was won without a drop of fuel being delivered by the pipeline. Immediately after the war most of the government system was decommissioned, but the 'Cold War' led to its reuse. In the 1950s new import facilities, civil storage depots (including large scale fuel reserves located in salt cavities) and pipelines were constructed. Increasing amounts of commercial fuel was also carried, with the system supplying fuel to both Heathrow and Gatwick airports. Following the end of Cold War, many more depots and some pipelines were closed. The use of the network for commercial aviation fuel, increased so new aviation fuel import facilities were connected to the system.

This pipeline network and storage system has constantly adapted, evolved and transformed itself. Fuelling the Wars sets out to chart how the system came to be built, its history and its continuing importance today.

Backing Bletchley Backing Bletchley
The Codebreaking Outstations, From Eastcote to GCHQ

By Ronald Koorm


This new hardback book, Backing Bletchley, takes an entirely new view of the WWII codebreaking operations - the rarely told story of the outstations that supported and complemented Bletchley Park. Well known for his codebreaking lectures, author Ronald Koorm explores the Y-stations, Wavendon, Gayhurst Manor, Adstock, Drayton Parslow, Letchworth, Stanmore and Dollis Hill that, after the war, evolved into today's GCHQ .

Backing Bletchley explores the complex relationship between Bletchley Park and its support codebreaking outstations, the background to the Enigma encoding machine and how Eastcote became the largest codebreaking outstation during the war. He analyses the development of improvements on Alan Turing's Bombe machine, the contribution of the WRNS (Wrens) in operating the machines and some of the social history showing how those Wrens, from varying social backgrounds, displayed outstanding teamwork under immense pressure at the codebreaking sites.

Post-war, Eastcote became GCHQ prior to moving to Cheltenham, and there were multiple uses of the site, including Cold War counter-inelligence operations. The author explores the link between Alan Turing and others in terms of the quest for Artificial Intelligence, and how talented individuals during the war helped shape the future. Backing Bletchley includes previously unpublished diagrams, charts and illustrations of the story of the outstations, which shed further light on the extraordinary historic events that occurred at them.

Backing Bletchley sets out, in a clear and very readable fashion, the complex interrelationship between Bletchley Park, its outstations and supporting infrastructure. It is a treasure-trove of information and thoroughly recommend for those interested in WWII code breaking.

The Secrets of the Enigma Machine and other Historic Cipher Machines

By Prof. Tom Perera, W1TP & Dan Perera



Many have heard about the Enigma machines of WWII but few have an understanding of the history of these impressive machines, how they work or went on to be developed. This fully updated second edition of Inside Enigma provides in depth detail on how these machines worked and why the even though the codes proved breakable that developments of this machine remained in service for many years after the war finished.

Inside Enigma has been written by established Enigma experts Tom and Dan Perera of the who's collection of Enigma machines have been used in Hollywood blockbusters such as the Imitation Game. This book brings to life how the Enigma machines were constructed, worked, used, how the messages were encoded and why the Enigma code was considered virtually unbreakable. You will find explanations of the code breaking efforts, the mathematics involved along with the Cold-War developments by the British, Americans and Russians. There is in depth detail of the machines used in this period, including the Swiss machines that were developed. The writers have also provided information on how to find your own Enigma machine and what can be involved in restoring one. If your efforts to find a machine fail, there are even guides to building your own or even making a simple code wheel to bring the code method to life. There is much else besides this included in Inside Enigma as it is both comprehensive and copiously illustrated.

If you want a book covering the secrets, theory and practice of the Enigma Machine in the 20th Century then Inside Enigma provides the ideal source.

The Future of Violence The Future of Violence
Robots and Germs, Hackers and Drones: Confronting the New Age of Threat

By Benjamin Wittes & Gabriella Blum


From drone warfare in the Middle East to digital spying, today's governments have harnessed the power of cutting-edge technology to awesome effect. But what happens when ordinary people have the same tools at their fingertips? Advances in cyber technology, biotechnology and robotics mean that more people than ever before have access to potentially dangerous technologies - from drones to computer networks and biological agents - which could be used to attack states and private citizens alike. The Future of Violence, details the myriad possibilities and enormous risks present in the modern world, and argues that if our national governments can no longer adequately protect us from harm, they will lose their legitimacy. The book also explains how governments, companies and citizens must rethink their efforts to protect our lives and liberty.

The way that technology is changing the threat landscape starkly highlights the importance of public policy in a way we have never seen before. The Future of Violence starts with the exciting "what if" stuff from assassinations by remote control spiders through to drones attacking sporting venues. The book goes onto explore the historical underpinnings that have led us to where we are today. Whilst all the threats discussed may come to pass this book throws a spotlight on the topic and provides a very thought provoking read.

HF Antennas for Everyone HF Antennas for Everyone
Edited by Giles Read, G1MFG


The RSGB has always published the very best antenna designs available to the radio amateurs. From the most complex to the very basic, these antennas have provided radio amateurs with much food for thought and practical designs to build. HF Antennas for Everyone draws on 90 of these RadCom and Radio Communication articles from the last forty years, providing a comprehensive collection of HF antennas, with something for everyone.

The selection in this book is a deliberate mix of the traditional and more recent designs. Sub divided into broad sections including horizontal, vertical and loop antennas, there is much variety to be found here. Looking back at the earlier decades it is amazing to see how many of the aerial giants, such as Louis Varney, G5RV have written for the RSGB. There is however much more than this. Conventional wisdom of HF antennas says you will need lots of space and money in order to put up suitable aerials. HF Antennas for Everyone shows that no matter the size of the available space you will find antenna designs that will help you get your signals in and out. Feeders are also not forgotten with a section devoted to this fascinating and often overlooked topic. But what if your local regulations prohibit the erection of antennas? That needn't get in your way, because this book even contains a section on Stealth antennas that are either essentially invisible or disguised as something quite different.

It is often said that there is nothing new in aerials, but HF Antennas for Everyone shows this isn't so. This book demonstrates a considerable number of developments and innovations from the last 20 years in particular, that show designers are starting to find innovative solutions to the age-old problems.

Whichever bands you want to work on, whatever the state of the sunspot cycle and however large or small your garden, in HF Antennas for Everyone you'll find an antenna that will get you heard.

Radio Auroras Radio Auroras


Radio amateurs know that sunspots affect VHF as well as HF propagation, and the solar cycle has a direct bearing on the prevalence of radio auroras. The extent and usefulness of this mode of propagation is perhaps still not widely known, though. Radio Auroras sets out to explain this phenomenon in an easy to understand and useful way.

Radio Auroras tells the fascinating story of the radio amateurs who discovered this mode of propagation and how they made use of it. Through the following pages there are descriptions of how auroras are caused, how they can be forecast and perhaps most importantly how best to use them to work DX. Whilst auroras are often thought to be a VHF effect, this book also describes radio auroras at 28MHz as well as outlining the effects of auroras on the other HF bands. Occurrences of Sporadic E can also accompany auroras to provide Auroral E propagation and this too is covered in Radio Auroras. If you are interested in radio propagation Radio Auroras is a unique guide to this topic, but for those studying and experimenting, or those keen to work DX on VHF, it is a real ‘must have’ book.

The Authors
The late Charlie Newton, G2FKZ, who wrote the core material of this book, was acknowledged as one of the leading experts on radio auroras and his material is judged as the definitive guide to this fascinating topic. He was for many years a leading light in the Radio Society of Great Britain (RSGB) Propagation Studies Committee. His work has been updated and supplemented with a new chapter compiled by well-known VHF DXer Neil Carr, G0JHC. Using contributions from a number of the UK's leading VHF DXers, Neil Carr looks at the major radio aurora events that took place during the last solar cycle and in the first part of the new cycle.

The Three Dimensions of John Logie Baird The Three Dimensions of John Logie Baird
By Dr Douglas Brown, GM8FFH


John Logie Baird (1888-1946) is remembered as the inventor of television but his work in colour, 3D and holographic television is much less well known. As are his significant contributions to other information sciences and their resulting technologies. The Three Dimensions of John Logie Baird sets out this work and adds a perspective not seen before to the story of this great inventor.

The Three Dimensions of John Logie Baird details the story of this great man from his early years through, to those where despite ailing health and poverty he did more to advance the early development of television than any other individual. He planted the seed, which has grown into a multinational, trillion dollar video and communications media industry. Baird is often dismissed as the person who invented a crude type of television which was quickly superseded but this book lays these criticisms to rest once and for all. For over a quarter of a century Baird developed monochrome, colour and 3D television, and many of the techniques he pioneered are still used in modern day systems. This book goes into detail about how the systems worked and their later development after John Logie Baird's death. The author has even provided projects that can be made which demonstrate the Baird's technology, including colour broadcasting.

The Three Dimensions of John Logie Baird is fascinating read that provides an excellent reference work on his inventions, an insight into the world of television and shows just how much we owe this great inventor.

The Birth of British Radar The Birth of British Radar
The Memoirs of Arnold 'Skip' Wilkins

Edited by Colin Latham and Anne Stobbs


Arnold "Skip" Wilkins is one of the unsung heroes of the British effort to develop radar. The Birth of British Radar book combines the memoirs of Skip with an authoritative overview of the historical importance of his work.

At the core of The Birth of British Radar are Skip's memoirs of his involvement in the British radar (or, as it was then known, radio direction finding, RDF) programme from its very inception in 1935. Working under the direction of Robert Watson-Watt, it was he who proposed using radio waves, bounced back from an enemy aircraft, to detect its position. Initially working entirely alone, he constructed prototype equipment which he used in the famous Daventry experiment conducted in a field near Weeden, Northants, on 26 February 1935. The success of this led to the establishment of the R&D group at Bawdsey Manor with its team of talented scientists, engineers and technicians. From there he describes the engineering and political developments which occurred to change faint traces into a fully working system which played such a crucial role in defending Britain in the Second World War.

This second edition of The Birth of British Radar has been greatly expanded from the original memoirs with a large array of additional material. Each chapter of the memoirs is set in a historical context with an explanatory note. There is a host of extra material including an interview with Skip, details of how radar grew, post war commemorations and much more. The Birth of British Radar contains mono and colour photos along with details of Skip's post war experiences. The story of this publicity-shy individual who never sought public recognition for his achievement, is fascinating. This book describes the struggles and triumphs from the earliest days of radar, in perhaps one of the most important periods in British electronics development, and is highly recommended.

Fort Bridgewoods Fort Bridgewoods
From Victorian Fort to WWII Y Station

By Stephen G Small, G4HJE


This is the story of a Victorian Fort that was obsolete before the last stone was laid yet in the early twentieth century became one of the most secret places in the realm. It was here that the developing science of radio became a vital weapon of espionage and war. Without the painstaking work of the expert civilian intercept operators Bletchley Park may well have failed to break the Enigma code and the vital allied intelligence advantage may have been lost.

Fort Bridgewoods - From Victorian Fort to WWII Y Station sets out this fascinating story from its building to its final closure in 1968. The early role as Fleet protection in the late 19th Century and even its WWI activities are detailed along with the significant characters involved in its history. Readers will find much about the highly secret WWII activity as a 'Y' Station which became one of the most important signal gathering stations in Britain's 'Enigma Code' breaking operation. This book is packed with information and readers will find that the radios and equipment used are covered in detail from the early Marconi equipment to the DST-100 receiver, designed specifically for wireless interception work through to the familiar HRO sets used later in the war and are even details of the Hallicrafters and RCA receivers used.

Whilst the World slipped slowly into the abyss of a Second World War the operators of Fort Bridgewoods skilfully developed the science of signals intelligence and were intercepting both the secret diplomatic and military radio traffic. Without Fort Bridgewoods the vital early 'breaks' of the Enigma code would certainly not have happened. Fort Bridgewoods - From Victorian Fort to WWII Y Station describes all of this and provides an insight into the operational work of this 'Y' station and its part in WWII. If you are interested in the radio interception technology of WWII and its pioneers this book is a revelation.

Cold War Secret Nuclear Bunkers  Cold War Secret Nuclear Bunkers
The Passive Defence of the Western World during the Cold War

By: Nick McCamley

Many will be aware that Britain is littered with a huge number of "Nuclear Bunkers" many of which are left over from the "Cold War". These relics represent the elaborate precautions that governments took to protect themselves in the event of nuclear war. However, for good reasons the precise nature of these arrangements has until now remained a closed book. Cold War Secret Nuclear Bunkers reveals for the first time the true extent of the preparations made.

Cold War Secret Nuclear Bunkers both surprises and fascinates with the scale and thoroughness of the installations and arrangements made. In the UK there were the London bunkers and the Regional War rooms built in the 50's to protect against the Soviet threat, and their replacement in 1958 by much more hardened, underground Regional Seats of Government and the unique Central Government War Headquarters at Corsham. The book also describes in fascinating detail a vast umbrella of radar stations that spanned from the Aleutian Islands through Canada to the North Yorkshire moors, all centred upon an enormous secret control centre buried below Cheyenne Mountain in Colorado. This is complemented in the United Kingdom with a chain of secret radars codenamed 'Rotor' built in the early 1950's, and eight huge, inland sector control centres, built over 100' underground at enormous cost.

Readers will find that Cold War Secret Nuclear Bunkers provides coverage of the UK Warning and Monitoring Organisation with its underground bunkers and observation posts, as well as the little known bunkers built by the various local authorities and public utilities. You will also find details of the various bunkers built for the U.S Administration, and developments in Canada. The book even examines the lack of provision for the general population, comparing the situation in the USA and the UK with the Soviet Union.

This book is a hugely fascinating read that details a huge array of bunkers in the UK and further afield. Recommended reading for anyone interested cold war history or just the details of these largely 'off limits' structures.
