bhi NCH Noise Cancelling Headphones

These new bhi NCH headphones use active noise-cancelling technology to reduce distracting background noise, providing a comfortable and restful listening environment in areas with high ambient noise. The headphones feature a miniature microphone in the earpiece that picks up ambient noise (like traffic noise and aircraft cabin noise) and the electronics in the earpiece invert the ambient noise by 180° out of phase with the external ambient noise. This has the effect of cancelling out the annoying ambient noise without diminishing the audio you are listening to, resulting in much improved listening experience.

The over-ear style NCH headphones also give a good passive audio isolation whilst the adjustable headband and soft over-ear pads make sure that the headphones are a comfortable fit. The NCH headphones require one AAA alkaline battery (supplied) and the active noise cancellation can be easily switched on and off with the simple switch and a green LED indicates whether it is active or not.

Active noise cancelling: 12 to 15dB
Impedance 32 Ohm
Magnet: Neodymium
Frequency Response: 20 - 20,000 Hz

By Steve Gibson

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

For those who are aware of it BRIXMIS (British Commander-in-Chief's Mission to the Group Soviet Forces of Occupation in Germany) is one of the most covert elite units of the British Army. They were dropped in behind 'enemy lines' ten months after the Second World War had ended and continued with their intelligence-gathering missions until the fall of the Berlin Wall in November 1989.

During the Cold Ware Berlin was noted as a hotbed of spying between East and West. BRIXMIS was established as a trusted channel of communication between the Red Army and the British Army on the Rhine. However, they acted in the shadows to steal advanced Soviet equipment and penetrate top-secret training areas. This fascinating book offers a new understanding of the complex British role in the Cold War.

Space Exploration
Past Present Future

By Carolyn Collins Petersen

**** SPECIAL RSGB MEMBERS ONLY PRICING - 50% OFF USUAL RETAIL PRICE ****

Humanity has always looked to the stars, but it hasn't been until relatively recently that we have managed to travel into space. Space Exploration takes us on a journey from the first space pioneers and their work. From the First World War led technological advances in rocketry that formed the basis for the Space Age, to the increasing corporate interest in space this book details our steps into sace. It is viewed from our potential future in pace on Mars to be exact and considers how we will reach that point. Space Exploration concludes with our current advances and our immediate ambitions in space exploration. The future and its scientific possibilities are enthralling: who will be the first to step on Mars? Will matter/antimatter annihilations take us to the Kuiper Belt, or will it be ion propulsion? What is the Alcubierre Warp Drive? Will it take us to the stars?

Space Exploration is a great hardback book that both entertains and enlightens where we may be going with space exploration and is a thoroughly recommended read.

Discovery of the Universe
A History of Astronomy and Observatories

By Carolyn Collins Petersen

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

This great hardback book charts the progress of astronomy through the observatories used throughout history, from the earliest such as Stonehenge to places like Birr Castle with its Leviathan telescope used by Herschel, places where the secrets of the universe were first unlocked by science. The Discovery of the Universe describes instruments now in use around the planet ranging from the Mauna Kea Observatories in Hawaii to the South Pole Telescope in Antarctica that hunts for the faint emission of the cosmic microwave background (CMB). In addition, astronomers today use an array of orbiting observatories and the ground-based observatories can now attain near 'Hubble' standards of accuracy, despite peering into space through our atmosphere.

The Discovery of the Universe looks at the amazing science that has been done using the world's suite of observatories. It presents examples of astronomical discoveries made across the widest spectrum as observatories extend humanity's vision across the depths of space and time.

X, Y & Z
The Real Story of How Enigma Was Broken

By Dermot Turing

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

In the bathroom of a Belgian hotel in December 1932, a French spymaster photographs secret documents - operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lay the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover name 'X, Y & Z'. By December 1942 in the middle of World War II the Polish code breakers are in France on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone for fear of capture so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, they could give away the greatest secret of the war.

This book X, Y & Z - The Real Story of How Enigma Was Broken describes how French, British and Polish secret services came together to unravel the Enigma machine. It tells of how Enigma code breaking continued in Vichy France and the how code breakers from Poland continued their work for Her Majesty's Secret Service, watching the USSR's first steps of the Cold War. The people of X, Y and Z were eccentric, colourful and caught up in world events that they could watch not control. This is their story based on original research and newly released documents it is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

House of Spies
St Ermin's Hotel

By Peter Matthews

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

St Ermin's Hotel has been at the centre of British intelligence since the 1930s, when it was known to MI6 as 'The Works Canteen'. Intelligence officers such as Ian Fleming and Noel Coward were to be found in the hotel's Caxton Bar, along with other less well-known names. Winston Churchill allegedly conceived the idea of the Special Operations Executive there over a glass (or two) of his favourite champagne in the early days of the Second World War, and the operation was started up in three gloomy rooms on the hotel's second floor, with the traitorous Cambridge Spies among its founders. When Stalin's Russia turned to a peacetime enemy in the Cold War that followed, Kim Philby and Guy Burgess handed over intelligence to their Russian counterparts in the dark corners of the hotel, while MI6 man George Blake operated as a Soviet double agent just across the road in Artillery Mansions. Meanwhile, St Ermin's proximity to government offices ensured its continued use by both domestic and foreign secret agents. In this paperback edition of the first book on St Ermin's, Peter Matthews, a witness to the intelligence battle for supremacy between MI5, MI6 and the KGB, explores this remarkable true history that is more riveting than any spy novel.

House of Spies is an intriguing book where the author, sometimes drawing on his own experiences in the less than glamorous world of secret operations uses the Hotel's links with spying events to plot a narrative involving espionage in both World Wars, the inter-war years and the Cold War.

QRP Scrapbook
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.

Forgotten Science
Strange Ideas from the Scrapheap of History

By S. D. Tucker

**** SPECIAL RSGB MEMBERS ONLY PRICING - 47% OFF USUAL RETAIL PRICE ****

Science has a reputation as the most logical and rational of human pastimes - but this has not always been the case. Some of them were genuine geniuses; others were simply lone loons. History is littered with their wreckage, and this hardback book tells the story of the very strangest.

From the inventor Nikola Tesla, who fell in love with his favourite pigeon and tried to broadcast his own thoughts, to the wannabe chemist August Strindberg, who injected apples with drugs to see if they could get high, numerous scientists have conducted bizarre experiments down the centuries. This book is packed with stories like this and from the most improbable to the frankly disturbing they make fascinating and thought-provoking reading. The author's eclectic mix covers a wide variety of material and with sections titled Evolutionary Dead Ends: Fairies playing at the bottom of Darwin's Garden and the like there is certainly plenty to ponder.

Proposing that science has become a kind of modern religion, and telling the tale of such noted pseudoscientific fads and fallacies as alchemy, spontaneous generation and the doomed quest to raise the dead, Forgotten Science can make you laugh at the same time as making you think. Science at school was never this weird.

By Andrew Barron, ZL3DW

The Icom IC-7300 radio is one of the best-selling radios of recent years but, as an owner or potential buyer, are you aware of all the features it has and how to get these set up and achieve the potential of the radio? The Radio Today guide to the Icom IC-7300 sets out to provide exactly what you want a practical guide that makes getting the most out of this radio.

Andrew Barron, ZL3DW, an acknowledged SDR expert, sets out in this book to highlight the myriad of options available to the users of this SDR - based radio. The Radio Today guide to the Icom IC-7300 doesn't duplicate the manuals that describe each button, function, and control but is a "how to do it" book with easy to follow step by step instructions. On opening the box of the Icom IC-7300 perhaps you will be surprised by how many settings and controls there are to learn. The inclusion of the 'panadapter' or 'band-scope' marks out the radio as being excellent value but there is a lot more. The radio has VOX (voice operated transmit switching), a built-in antenna tuner, coverage of the 6m (50MHz) and 4m (70MHz) amateur radio bands. And it has a voice keyer, RTTY and CW keyer memories, and an RTTY decoder. These all need effort to setup well and the easy to understand tips and explanations Andrew provides are invaluable in doing so. There are guides to setting up the various operating modes and the section on setting up the PC software digital mode program for FT8 will be the first turned to by many. The book certainly doesn't stop here either as there are also sections on troubleshooting, reviews of modifications that some have made, links that will extend your knowledge further and much more.

The Icom IC-7300 is a great radio and if you want to get the most out of it the Radio Today guide to the Icom IC-7300 provides invaluable reading and the insight that is illuminating for every owner or potential purchaser.

Inside Enigma
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 enigmamuseum.com 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.

Last Train to Hilversum
A journey in search of the magic of radio

by Charlie Connelly

This new hardback book reminds us about the wonders of radio. In the UK 90% of the adult population listens to broadcast radio every week. That is almost 49 million people listening for on average 21.3 hours a week each.

Written by Charlie Connelly a bestselling author and award-winning broadcaster the Last Train to Hilversum is a witty and informative look back over the years of British broadcast radio. Packed with anecdotes from the sublime to the ridiculous Charlie explores its geniuses, crackpots and charlatans who got us to where we are today. He remembers its voices, personalities, programmes and visits the key radio locations from history.

From the Dame Nellie Melba's first broadcast 1920 from Marconi in Chelmsford to amongst others the Derby Wireless Club, through to the first commentary on rugby from Twickenham where the summariser asked "Do they always use an oval ball?" and had no understanding of the rules of the game. There is even a chapter devoted to the SOS appeals made by the BBC from the 1920s to 1950s at the rate of a thousand a year, more fascinating might be the appeals not broadcast at the time including the rather unsavoury appeal offering a £5 reward for anyone 'to bring my wife home for a good hiding'. There is detail of the pirate radio stations, Radio 1, Test Match Special, the Today programme on Radio 4 and the solemn, rhythmic intonation of the shipping forecast - in many ways, our lives measured in kilohertz.

Part nostalgic eulogy, part social history, part travelogue, Last Train to Hilversum is simply a great read that explores our relationship with broadcast radio from its earliest days to the present. Recommended reading for everyone.

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.

Test Equipment for the Radio Amateur
5th Edition
By Philip Lawson, G4FCL

This book is aimed at the radio amateur, listener and electronic enthusiast who wants to make a variety of measurements without necessarily spending a fortune on expensive test equipment. It is a very practical book, designed to help you develop care and skill in making the most common and important measurements, quickly, safely and affordably.

In this new fifth edition of Test Equipment for the Radio Amateur, the reader will find, for the first time, extensive links to internet sources for access to the very latest information on construction projects, equipment and measurements. The sections on commercial and home-brew equipment have been separated for clarity, new items added and some dated items removed. Timeless reference data has been retained; some items of technical theory have been given their own section, and extended, for those who wish to deepen their understanding of these areas. Written in an extremely readable style this book represents a significant update to, and restructuring of, the previous edition.

This book is designed to give an overview of how each item of test equipment works, what it can be used for and even how much it might cost. Many general measurements, plus specific measurements on transmitters and receivers, are described in detail. Matters such as the effect of the test equipment on the circuit to be measured are especially considered, so that the measurement results may be interpreted correctly. A large section of the Test Equipment for the Radio Amateur is devoted to home construction, as it is frequently possible to make an extremely useful item of test equipment for a fraction of the price of its commercial counterpart, and there is the added benefit of the practical skill and learning that comes with such a construction project.

Test Equipment for the Radio Amateur is a practical guide to getting the most out of your equipment and understanding exactly how your station is performing. It is simply a must have book for every radio amateur.

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'.

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. Anyone can give portable operating a try and this book shows that portable operators use HF and VHF bands, as well as SSB, FM, CW, and digital modes. There are chapters dedicated to organising your equipment, radios you can use, power sources, portable antennas, the on air activities and even a handy online resource listing.

This book provides something for everyone, if you want to activate from a picnic table at a nearby park, or a remote summit, Portable Operating for Amateur Radio offers a wealth of practical information to help make your portable amateur radio operations successful.

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.
