Interesting articles - mainly amateur radio - UK Vintage Radio Repair and Restoration Discussion Forum

David G4EBT · 16th Sep 2016, 11:44 am

There’s a nice selection of articles, mainly amateur radio, but not exclusively, from radio magazines of the 1950s, 1960s and 1970s by David M Pratt G3KEP, David Noble G3MAW and Graham F Firth G3MFJ at the link below. David Pratt was for many years, the Chief City & Guilds Examiner for the Radio Amateurs’ Exam until the C&G felt that the RAE no longer fitted in with the C&G ethos as a vocational training and accreditation body, rather than for hobbyists.

David designed a 200 MHz digital frequency counter using nixie tubes way back in the late 1960s which featured in Radcom, and which I built successfully.

Hope the articles are of interest.

David's web pages also include a full collection of RAE papers - including the one I took (and passed) in May 1973.

I took (and passed) the May 1974 exam, but the RAE course fell short of what I'd hope for, as I was primarily interested in construction, though the course and exam were not intended to give us a good solid grounding in the hobby - it was only meant to minimise the risk of us causing interference to other spectrum users. The current three-part licensing structure and tuition gives a much more solid grounding, with practical work and on-air contacts.

Quint to see on the exam papers that Cassel's Log tables were provided back in those far off days when pocket calculators were a rarity, and would doubtless have been seen as 'cheating'!

Below is the 200MHz nixie tube digital frequency counter I built from David's Radcom design at a time when a commercially produced counter would have ben far beyond my means.
