Gilbert Davey had become interested in radio as a boy when his father asked a friend to build the family a three-valve receiver (detector and two LF stages).   Seeing the boy's interest, the builder of this set gave Gilbert some spare components and old magazines, and he started to experiment. (1)

He had the use of a garden shed as a "shack" which, although self-contained, suffered somewhat from damp. (2)   Enthusiasts in the 1920s and 1930s often had to make their own components, especially coils.   If a set worked first time, this was a great surprise.

As a young man, Davey followed technical developments with interest.   When Wireless World published a design for a resistance-coupled "Quality Amplifier" in the mid-30s, he saw it as a sign of hope for real improvement, even though there was no broadcast input source available then that could do it justice.   The innovation of negative feedback shortly afterwards was equally promising. (3)

During World War II, Davey served in the Royal Signals, achieveing the rank of Major.   He is believed to have taken part in clandestine operations in France, but said little about these exploits. (4)   Stationed in Germany at the end of the War, Davey was the first British amateur to operate a transmitter in the British sector of Berlin, and made contact with all parts of the world with just 10 watts' transmitting power. (5)   After his return home, he took up employment with the Pearl Assurance Company in 1947. (6)   He was to remain with Pearl Assurance for the rest of his working life, occupying various posts at Pearl offices in the West End, Edgware and latterly Peterborough. (7)

Quite by chance, Davey's interest in radio became known to the new Editor of the Boy’s Own Paper, Jack Cox, and he began contributing radio designs and articles. (8)

The Boy’s Own Paper, that bastion of British morality, had been severely limited by paper shortages during the war, and this continued for some time.   Gilbert Davey’s articles sometimes appeared without circuit diagrams or practical layouts; the additional details were only sent out to those who wanted to build the sets.   A succession of Davey designs was published during the late 40s and the 50s, calculated to appeal to the active older boy.   They included an early version of the beginner’s one-valver (see DAVEY 1-VALVER HISTORY page), a simple three-valve set, an all-mains two-valve receiver, a high-fidelity amplifier, a “holiday” radio set, a portable cycle radio (not to be used on the move!), and a bedside radio.   The BOP constantly carried advertisements from training colleges and the armed services inviting boys to train as radio operators or technicians (demand far exceeded supply), as the advertisers doubtless knew of the popularity of his articles.

By the time he appeared in the Studio ‘E’ series (September - November 1957), Davey had been a regular contributor to the Boy's Own Paper for over ten years.   An article in the December 1957 BOP entitled “Hobbies for the Modern Boy” (unattributed but probably written by Jack Cox) carried this passage revealing just how popular his articles were:

"Gilbert Davey has topped the popularity poll among BOP contributors for the past ten years.   This is all the more surprising when you realise that he rarely has more than three articles a year in the magazine.   But his subject is Amateur Radio and that seems to be just about the most consistent of all boys' hobbies.

"Television has had no effect whatever on the making of sound radio sets by keen and enthusiastic amateurs - in fact, the reverse!   Gilbert Davey started his first BBC Television series in the Studio ‘E’ programme in October last, showing viewers how to make a simple one-valve radio set.   Within a few days of the first programme he had received over 26,000 letters!

"What is the secret of Gilbert Davey's popularity?   In the first place he is a skilled amateur who is tremendously enthusiastic about his hobby.   He is not a radio dealer or a professional radio engineer; in fact he is an insurance inspector who lives in Middlesex.   Jack Cox, Editor of BOP, found him by sheer chance ten years ago, and he has worked exclusively for BOP ever since.   He has had 8,000 letters in a week from BOP readers.

"The sets which Gilbert Davey designs and builds, and then shows you how to make in simple language, are those which appeal to boys.   A Portable Cycle Radio Set, a Three-Valve Receiver for Bedside or Camp, a Midget Two-Valve Receiver are typical.” (9)

  In October 1957, at the same time as the BBC Studio ‘E’ series, Davey's first book, Fun with Radio, was published by Edmund Ward.   This featured designs that had appeared in the Boy's Own Paper over the previous eleven years, and was edited by BOP editor Jack Cox.   Although his constructional articles for the January and October 1957 editions of Boy's Own Paper had featured the newly available transistors, no transistor designs appeared in Fun with Radio for the stated reason that they were still too experimental and could be an expensive risk for the young amateur. (10)   This suggests that Fun with Radio was in preparation for some time - perhaps more than a year - before publication, and the reason given for not including transistor designs reflected the author's opinion at the outset of preparing the book.   Later editions did feature transistor designs.

In March - April 1959, Davey appeared on Focus (the re-named Studio ‘E’) with a two-transistor radio design (the BBC Archive does have this leaflet). (11)   Demand for this was nearly as keen as for the Studio ‘E’ leaflet; there were 25,000 applications immediately, followed by a steady demand of around 100 requests per day for some time. (12)   (I have no evidence that he appeared on Blue Peter once it had supplanted Studio ‘E’ and Focus in catering for children of all ages.   He appeared on ITV, but I have not so far researched these appearances.)

Several Davey Boy’s Own Paper designs were reprinted in the Boy's Own Companion and the Boy’s Own Annual, both offshoots of BOP.   The June 1961 BOP and the 1962 Companion featured an interesting metal-chassis version of the beginner's one-valver (see DAVEY 1-VALVER HISTORY page).

'Lady Jayne' hair clips,    
ancient and modern.
   

It was the ladies of his family who 
came up with the ideal solution . . .
One simple but useful idea for constructors came from a quite unexpected quarter.   This was passed on in the November 1963 BOP.   With the advent of transistors, Davey had been looking for a way to avoid the need for a “third hand” to hold the pliers serving as a heat-sink when soldering these and other heat-sensitive components.   It was the ladies of his family who came up with the ideal solution – a ‘Lady Jayne’ sprung metal clip, as used by hairdressers when setting hair! (13)

As a contributor, Gilbert Davey was one of the panel of BOP experts who answered readers’ queries.   Occasional correspondents innocently asked for details to build transmitters, and always received stern reminders from him about the stringent requirements – including a radio theory exam and a 12 words-per-minute Morse code test - before a GPO transmitting licence could be granted. (14)

Lest it be thought that all Davey's correspondents were relatively well-off British boarding-school types, he received letters from BOP readers throughout the Commonwealth.   Indeed he is reported to have remarked that some of his most enthusiastic correspondents came from the poorest districts of South Africa. (15)

The Boy’s Own Paper faced difficult times in the early sixties with the rise of the pop music industry, competition from other teen magazines, and the fact that copies of BOP were often shared among many readers - a practice that had been actively encouraged during and after the war.   Davey designs of this period included a shortwave receiver capable of progressive upgrading, and a basic electric guitar using a headphone as a transducer.   The Boy’s Own Paper ceased publication in early 1967, although its offshoot Boy's Own Annual survived into the mid-1970s.

Later, Jack Cox recalled that technical and hobby articles had always been well received; as a young BOP reader, he had built radio sets himself to the designs of an earlier contributor.   Indeed, he went so far as to wonder whether he should have shifted the magazine’s emphasis toward these topics and away from the derring-do fiction for which it is chiefly remembered. (16)

Gilbert Davey went on to write several more Fun with . . . books, all edited by Jack Cox, including Fun with Short Waves, Fun with Electronics, Fun with Transistors, Fun with Hi-Fi and Fun with Silicon Chips in Modern Radio.   This, the last title to be written, was published in 1981, the year of Jack Cox's death.   Fun with Radio ran to six editions in the UK; the sixth was published in 1978 by Kaye & Ward.   (Editions often seen listed as published in the USA by Sportshelf & Soccer Associates in 1986 appear to be imports of UK editions.   For fuller details of articles and books, see DAVEY SOURCE LIST page.)

Both as a contributor to Boy's Own Paper and as author of his own books, Davey often sought or was offered products to try out and report upon.   He stressed that when commenting on an item of equipment he did so in order to inform his readers about that general class of product; he did not necessarily believe that a product he mentioned was superior to a rival product. (17)   One tape recorder did come in for some gentle criticism, and some rigorous testing.   This machine could not faithfully play tapes recorded on other machines because it ran at "differential speed", i.e. a non-standard tape speed.   However its push-button controls survived undamaged when thoroughly tested by Davey's daughter and her friends! (18)

He never pushed theory too hard, but encouraged his readers to learn circuit symbols, and perhaps ease themselves into the theory by taking a radio periodical or consulting theory books at a library. (19)

Safety was dealt with carefully - this was especially important for the mains-powered designs, many of which did not use isolated power supplies.   Davey always advised using a loudspeaker, rather than headphones, with mains-powered sets. (20)   Advice was given on proper earth connections where appropriate, and switching off when possible before carrying out adjustments. (21)   Properly constructed cabinets were insisted upon for mains-powered sets, to protect young children and inquisitive pets, especially cats. (22)   One wonders whether the specific mention of cats was the result of unfortunate experience; if so, one can but hope that Tiddles survived with just a fright and temporary loss of dignity!

Throughout Davey's writing career, his articles and designs kept pace with new developments (silicon chips and kit-sets, for example).   But he continued to include simple crystal and valve designs - in spite of some reviewers’ criticisms - so that young experimenters could have the chance to grasp first principles and also make use of old components. (23)

He did admit to difficulty reconciling himself to some aspects of technical progress.   He regretted the demise of the old 2-volt valve types whose freedom from background noise had been so valuable for short-wave receivers. (24)   He found it hard to ascend the learning curve when transistors took over, but knew he must because they were the future. (25)   He was dubious when quadraphonic sound systems were announced in the early 70s; were humans destined to develop four ears? (26)

As an amateur himself, Davey tried to keep in mind the problems faced by the young constructor: lack of experience and skill, lack of tools or test gear, and especially the changing availability of components.   Thus when the beginner's one-valver first appeared in Boy's Own Paper in February 1948, it featured an easily-available 2-volt triode and a home-made coil.   When miniature pentodes and commercially-made coils became available, the design was adapted to take advantage of them.   For later versions, when commercially-made coils to suit the simple circuit had become difficult to obtain, a home-made coil was once again featured.

Gilbert Davey was proud of his long association with the Boy's Own Paper and its offshoot publications, and with Jack Cox.   He was equally gratified that he had introduced thousands of boys and girls to a fascinating hobby and, in many cases, a rewarding career. (27)   All the while, he kept his life with Pearl Assurance and his writing career quite separate.   To his Company associates he was quiet, modest and unambitious; they knew little or nothing of his spare-time radio writing career or the huge postbags that it used to bring him. (28)

Gilbert Davey died at Peterborough on 6 April 2011, aged 97.
