Wireless World

Information about Wireless World

Wireless World was the pre-eminent British magazine for radio and electronics enthusiasts. It was one of the very few "informal" journals which were tolerated as a professional expense.

History

The Marconi Company published the first issue of the journal The Marconigraph In April 1911 . It was the first journal written especially for wireless communication and circulated largely among engineers and operators.

In 1913 the name was changed to The Wireless World and in April the first issue was seen in the news-stands.

From April 1922 it was known as The Radio Review. This journal was first published October 1919 and ended as part of The Wireless World.

Target audience

It was also aimed at home constructors, publishing articles on building radio receivers and, after the BBC started regular 405-line TV programmes from Alexandra Palace in 1936, complete details on building your own TV set - including the winding of the high-voltage CRT deflector coils (not a task for the faint hearted). A similar series was published after 1945 utilising the then ubiquitous EF50 RF amplifier valve (tube).

Famous articles

In 1945 it published a famous article by Arthur C Clarke (then of The British Interplanetary Society) which foresaw the coming of communications satellites in synchronous orbit around the Earth.^[1]

Audio

As well as being a place where many famous audio pioneers shared ideas, with articles on the 'Dinsdale Amp' and the 'Linsley Hood' power amp, it also published articles on building the famous "Williamson amplifier" by D.T.N Williamson - using a pair of triode connected KT66s (very similar to the American 6L6) in push-pull to give 15 Watts output. In 1955 it published the design of the popular Mullard 5-10 audio amplifier using two EL84s in ultra-linear push-pull configuration. Later, in 1975/6 it published a design for the decoding of broadcast TV Teletext information before the first commercial decoder became available in the marketplace.

Computers

In 1967-1968 a series Wireless World Digital Computer by Brian Crank was published. This described how to build a very simple binary computer at home. It was constructed entirely from reject transistors (to keep the cost down) and was intended for teaching the basic principles of computer operation. Around 1979 they published a design for a "scientific computer" which was sold as the PSI Comp 80 in kit form by the company Powertran.

Contributors

Contributors included M.G. Scroggie, who also had an anonymous column cleverly entitled "Unbiased" by "Free Grid", exploiting the British skill at punning. Amongst the early editors was W.T. Cocking (designer of the WW television sets); the last four editors were Tom Ivall, Frank Ogden, Martin Eccles, and Phil Reed. The current editor is Svetlana Josifovska.

Recent times

In September 1984 the title was changed to Electronics and Wireless World. The magazine is still published, but under the title Electronics World, and is available from major magazine stores or by subscription.

A sister publication was "Wireless Engineer" which was more of a learned journal than a popular magazine, featuring high quality articles.

Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
