Testing 123
Measuring Amateur Radio Performance on a Budget

By Andrew Barron ZL3DW

Is your station performing as you expect? Are the bands dead, or has your receiver developed a fault? Maybe your antenna system has a problem? How do you check?

Written by acknowledged expert Andrew Barron, ZL3DW, Testing 123 sets out to provide solutions to find out how your station is performing. From cheap test equipment and free software through to more advanced testing methods that the professionals perform, Andrew provides insight into what you can do to analyse and improve your station.

As every radio amateur wants to protect their investment in their radio setup, it is a good idea to make sure that your radio equipment and antenna system is in top notch condition. This book shows the why, when and how of testing that you can do without investing a lot in expensive test equipment. Testing 123 also explains the numbers in those magazine reviews that tell you about the radio being tested. There is explanation of why these numbers are important and how you can read them to understand just how good or poor the reviewed radio is. So, even without investing money in a lot of test equipment you can read the to get an appreciation of how ‘lab testing’ tests are carried out, the ‘real world’ situations they emulate, and what the results tell you about the radio.

Many people have been involved in the hobby for years and have never tested anything but what happens when something does go wrong? Will you even know there is a problem and if you do, how will you identify the cause and fix it? Covering from the antenna through the receiver & transmitter and onto power supplies & earths, Testing 123 provides solutions to the questions you have and much more.

The Magic Bands
A Guide to 6m and 4m Amateur Radio

By Don Field G3XTT

The Six Metre (50MHz) and Four Metre (70MHz) bands are known as the 'Magic bands' by radio amateurs across the world. Written by the well-known 6m enthusiast Don Field, G3XTT, this book provides a comprehensive guide to these fascinating bands and lets you into the secrets that make them so popular.

The 'Magic bands' attract a special kind of enthusiast, someone who is prepared to put in long hours on a seemingly dead band, waiting for a fleeting opening or finding ways to make QSOs by means of meteors or even by reflecting signals off the moon. Propagation on these bands, especially 6m, lies between that of the HF bands and that of the higher VHF/UHF bands, and often brings surprises to those who are prepared. As such, these bands attract enthusiasts from both the HF and VHF worlds.

The Magic Bands builds on Don's earlier books the 6 Metre Handbook and Six and Four by adding lots of material on data modes operation, which has grown enormously in popularity in recent years with the advent of FT8. There is detail of the many of the new radios that have appeared in recent years with 6m and, increasingly, 4m capabilities. Readers will find two new antenna designs from Justin Johnson, G0KSC, of InnovAntennas especially produced for this book. There is detail of software too, not just for data modes but for remote operation, tracking of achievements and much else. There is even material highlighting the achievements of several of the leading operators on the 6m band.

The 6m band is now almost universally available across the amateur radio world, while in recent years 4m access has been granted to many more countries, often on a permanent basis. So why miss out on the 'Magic bands'? The Magic Bands is recommended for anyone who wants to try these bands out and is a comprehensive guide for those who are already hooked on these fascinating pieces of spectrum.

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

** SPECIAL MEMBERS ONLY PRICING - 40% OFF USUAL RRP **

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.

SIGINT
The Secret History of Signals Intelligence in the World Wars

By Peter Matthews

!!!! BACK IN STOCK AS A PAPERBACK !!!!

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

The Paraset Radio
The story of a WWII Spy-Radio and How to Build a Working Replica

By Hiroki Kato, AH6CY

This book describes the gripping story behind the Paraset - a unique spy-radio, dropped behind enemy lines in the dark days of WWII. This radio being both light weight and state of the art for the time was concealed in a suitcase, making ideal for use by the spies of SOE. This book describes how the Paraset was used, the technical specification and even how you might build your own replica.

Written by acknowledged Paraset enthusiast Hiroki Kato, AH6CY this book was inspired by the epic stories connected to this radio and is meticulously researched. These radios were first made in workshops in England at Whaddon Hall and then at Little Horwood, near Bletchley Park. Sadly, most were destroyed at the end of the war and today only a few original Parasets remain in museums and the hands of private collectors. However, inspired by the Paraset stories, radio amateurs across the world have been building working reproductions.

The Paraset Radio provides a history of this remarkable Morse code only radio that was low power (4-5W), had no meters or even an on/off switch. Hiroki relates how the SOE Agents used the radio in occupied Europe and how the radio was developed during the war. There are schematics of the design of the radio along with advice on how to build your own working example that can be used on amateur radio bands. There is also information on building a Paraset from one of the kits available. Hiroki even shares details of some of use he has put his own Paraset radio to on the amateur radio bands.

The Paraset Radio is a rare insight into a radio that provided vital spy communications in WWII. It may also provide the inspiration for you to build your own working Paraset radio, so that you can get a taste of wartime operating, but without the danger of a fatal ‘knock on the door’.

EMC and RFI Know How

Edited by Steve Telenius-Lowe, PJ4DX

Many radio amateurs have Electromagnetic Compatibility (EMC) issues or, as it is more commonly referred to in the US, Radio Frequency Interference (RFI). As a scourge of our time there has been much written about this topic as to cures, identifying the problems and much more. EMC & RFI Know How sets out to draw this material together and provide valuable insight into an area that is considered by many to be one of the most important problems facing amateur radio today.

This book has drawn on expertise from across the world and includes material from the UK, USA, Germany, Greece and the Netherlands. You will find sections dedicated to sources of interference such as Lighting, xDSL, Renewable Energy, Air Conditioners, Air Source Heat Pumps, Power Line Noise and Power Supplies & Chargers. EMC & RFI Know How also takes the reader through practical ways of defeating the problem of interference. Home constructors are well catered for with the circuit of an HF receiver suitable for directionfinding, a preselector to eliminate interference from powerful broadcast stations, filters to stop breakthrough to TVs, and even a ‘QRM-Eliminating’ antenna. Advice is also given too on how to prevent breakthrough from amateur transmissions spoiling the family’s enjoyment of television programmes!

The average home contains numerous electronic devices that can potentially cause interference in the amateur radio spectrum. EMC & RFI Know How takes a detailed look at how this interference can occur -- and how it can be defeated. If you suffer EMC and RFI problems or not, this an essential book for every radio amateur’s library.

Modern Views of Electricity
By Oliver J. Lodge, D.Sc., LL.D., F.R.S.

When Oliver Lodge started working with electricity, he was following in the footsteps of Heinrich Hertz who had produced and detected electric waves. He identified electromagnetic radiation independent of Hertz’s proof and, at his 1894 Royal Institution lectures, Lodge demonstrated an early radio wave detector he named the “coherer”. This great British physicist and writer was involved in the development of, and holder of key patents for, radio. In 1925 he also became the President of the Radio Society of Great Britain (RSGB).

This 1889 book originally published by MacMillan was authored when the understanding of electricity was still evolving and had not yet begun to be explained in the terms that are well established today. Republished today by the RSGB it provides a unique insight into the world of electricity as it was seen in the Victorian age. Broken into four sections and fifteen chapters you will find Lodge’s 19th century views of Electrostatics, Conduction, Magnetism and Radiation. There is discussion of how they were producing currents, thoughts on the conduction of gases, the structure of magnetic fields, the relation of magnetism to electricity and even the relation of ether to electricity and the constants of the ether. Lodge goes further still describing electrical radiation as light and considers the electro-magnetic and electrostatic effects on it. Illustrated throughout you will find reproductions of Leyden jars, coils and the like alongside diagrams of how to generate electricity.

Published as part of the RSGB Historical book collection, Modern Views of Electricity provides, not only a tribute to the work of a past RSGB President, but also a fascinating look back at the developing years of electricity and radio as it was perceived over a century ago. As the author concludes "a book dealing with electricity at the present time is to herald the advent of the very latest discoveries and prepare the minds of the reader for more" - it certainly does.

Codebreakers of Bletchley Park
The Secret Intelligence Station that Helped Defeat the Nazis

By Dermot Turing

**** SPECIAL RSGB MEMBERS ONLY PRICING - 30% OFF USUAL RETAIL PRICE ****

At Bletchley Park, some of Britain’s most talented mathematicians, linguists, and intellectuals were assembled to break Nazi codes. Kept secret for nearly thirty years, we have now come to realise the crucial role that these codebreakers played in the Allied victory in WWII.

Written by Dermot Turing - the nephew of famous codebreaker Alan Turing - this illustrated account provides unique insight into the behind-the-scenes action at Bletchley Park. Discover how brilliant and eccentric individuals such as Dilly Knox, Alan Turing and Joan Clarke were recruited, the social life that grew up around the park, and how they dealt with the ever-present burden of secrecy. Dermot looks at the growth and evolution of the Bletchley codebreaking through the stories of the people who worked there. In following that story, surprises emerge and the lives of the people whose contributions have been lost are rediscovered.

Codebreakers of Bletchley Park brings to life the stories of the men and women who toiled day and night to crack the seemingly unbreakable enigma code. This book is highly recommended to everyone who is interested in not only the development of Bletchley Park as a codebreaking centre but also the people who made it happen.

Fuelling the Wars
PLUTO and the Secret Pipeline Network

By Tim Whittle

**** SPECIAL RSGB MEMBERS ONLY PRICING - 20% OFF USUAL RETAIL PRICE ****

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
The Codebreaking Outstations, From Eastcote to GCHQ

By Ronald Koorm

**** SPECIAL RSGB MEMBERS ONLY PRICING - 30% OFF USUAL RETAIL PRICE ****

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.

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

By David Abrutat

**** SPECIAL RSGB MEMBERS ONLY PRICING - 24% OFF USUAL RETAIL PRICE ****

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

Getting started in EME
Earth - Moon - Earth Transmissions

By Stephen Appleyard, G3PND and Philip Malme, G4PQP

Bouncing signals off the Moon has always been considered as one of the most difficult of the amateur radio disciplines. Traditionally Moonbounce as it is known was practised by amateurs who are the most accomplished engineers as well as operators but recent developments have now made it more accessible than ever before. Get started in EME sets out to explain what you need to know and how to get started in this captivating area of amateur radio operation.

Get started in EME sets out the history of Moonbounce, gives information on the various EME bands and the reasons for choosing them and then explains the EME signal path. It covers the unique propagation effects such as libration fading, Faraday rotation and spatial offset. Ground gain, Doppler shift and degradation are also covered. The book is practically based and focuses on EME at 144MHz (2m) and proposes, wherever possible, the use of equipment that is already owned, in order to reduce the cost of getting started in EME. This is particularly the case with antennas but you will also find coverage of transceivers, pre-amplifiers and power amplifiers. Again the emphasis is on the minimum possible requirement, utilising equipment that may already be in the shack. There is coverage of computers/interfaces, software and operation requirements and even your first EME contact! EME at 70cm is covered and there are glimpses where the newcomer to EME might move on to, when they find themselves bitten by the Moonbounce bug.

If you have never tried EME transmissions or are just interested in what it takes to make that first contact made by bouncing a signal off the Moon then Get started in EME will provide the ideal introduction.

Quote: "Stephen Appleyard and Philip Malme have done an excellent job with the EME book. It aims at the right level, achieving a good balance between completeness and accessibility. Perhaps most importantly, it makes EME appear as something that nearly any amateur radio enthusiast could achieve, with some dedication of time and effort." Joe Taylor, K1JT

ARRL Magic Band Antennas for Ham Radio
6 Meter Antennas You Can Build

By Joel Hallas, W1ZR

For many, six metres (50MHz) is known as the 'Magic Band'. Its unusual propagation and characteristics have long made it a fascinating challenge for radio amateurs. This new book from the ARRL Magic Band Antennas for Ham Radio is designed for radio amateurs who want to discover the mysteries of the magic band and the surprises it holds.

ARRL Magic Band Antennas for Ham Radio provides an insight into what to expect in the six metre band, alongside tips on operating and getting the most from this quirky band. As the title suggests, the book is primarily dedicated to antennas you can build that will give the best performance in the magic band. You will find an array of beam antennas along with a variety of loops, dipoles and more that give lots of options for your particular location. Some antennas are also effective on a range of frequencies so you will, for example, also find a 160m to 6m 'hidden antenna' and an X Beam that covers 2m and 70cm as well as the magic band. There are detailed instructions for building these designs that range from the simple to the complex.

When you least expect it, six metres can suddenly open for contacts over hundreds and even thousands of miles. And while the HF bands may be suffering during a Solar Minimum, six metres is just amazing. If you're looking for new pursuits in amateur radio, the world above 50MHz is the territory you could explore and ARRL Magic band Antennas for Ham Radio may just help you to do that.

ARRL Portable Operating for Amateur Radio
By Stuart Thomas, KB1HQS

For many amateur radio stations are traditionally home based and associated with a table full of gear. However in recent years many have taken on the challenge of operating portable, away from home. A new generation of compact, full-featured, portable radios combines with modern battery technology to make it easier than ever to set up your station and enjoy amateur radio in the great outdoors. This book sets out to show what is possible and the fun to be had when operating portable.

With the increase in organised outdoor operating activities by clubs and award programmes such as SOTA, it's no wonder that more radio amateurs have been inspired to venture into portable operations.

ARRL Receiving Antennas for the Radio Amateur
Transmitting and receiving antennas have different jobs to do
By Eric P. Nichols, KL7AJ

Although the fundamental characteristics of antennas apply to both transmission and reception, the requirements and priorities of receiving antennas can be vastly different from those of transmitting antennas. Receiving Antennas for the Radio Amateur focuses entirely on active and passive receiving antennas and their associated circuits. There are relatively few cases where a radio amateur cannot benefit from a separate, well-designed receiving antenna or antenna system. On the low bands, including our new allocations at 630 and 2,200 meters, heavy emphasis on the receiving end of these radio paths is essential for success.

The active antenna holds a prominent position in Receiving Antennas for the Radio Amateur, as it offers good receiving performance while taking up minimal space. Recent developments in radio frequency (RF) semiconductors, especially low-noise RF operational amplifiers, have made a number of previously difficult-to-implement active antenna designs a very simple task. Receiving Antennas for the Radio Amateur is a wide ranging book readers will find chapters covering Preamplifiers, Power Gain, Small loops and a wide array of other antennas. There are chapters on LF, NVIS, Propagation and of course Antenna Projects, Construction Techniques and a lot more.

If you are looking to maximise your receive capabilities, this book provides the ideal guide to this topic and is a must for every radio amateur's bookshelf.

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

By Benjamin Wittes & Gabriella Blum

**** SPECIAL RSGB MEMBERS ONLY PRICING - 28% OFF ****

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.

The Voices
Spying and Radio Warfare During the Cold War

By Gordon Adams, G3LEQ

Many are aware of the spying activity that took place following WWII until the demise of the Soviet Union in 1991. Few though are aware of the radio jamming, broadcasts of encrypted messages or any of the other electronic skulduggery that took place during this time. This book shines a light on these activities that range from the extraordinary to the most mundane but most disruptive imaginable.

Readers of The Voices will find the details of the radio warfare engaged in the Americans, Soviets and British along with a number of other countries and groups from the Middle-East to the Caribbean. You will find details of the author's first experiences of radio jamming that lead to his deep fascination as to what was going happening on the airwaves at this time. There is discussion of the activities of propaganda stations such as Radio Marti, Radio Liberty, Radio Free Europe and many others. The mysterious Numbers Stations, their coded messages and the non-attributable callsigns are explained here. The author talks about where the spies operated from and the radio traffic they generated. There is a chapter on Orford Ness and the still secret Cobra Mist project along with a reflection of the role of Cyprus and the UK's Sovereign bases. There is even detail of the role of the BBC and their World Service during these times.

Produced as a tribute to the late, Gordon Adams, G3LEQ this book is based on series of articles first published in RadCom in 2000-2001 and a fond remembrance of someone whose tireless efforts influenced the RSGB for many years. This book has edited from those articles and expanded with new pictures and small amounts of material omitted from that series.

The Voices book is a truly eye-opening read for those who are unaware of this part of our history. It is simply thoroughly recommended reading for those interested in the Cold War and the radio warfare that took place in the latter part of the 20th Century.

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.
