After finishing WftW Volume 4 ‘Clandestine Radio’ in 2004, numerous photos, circuit
diagrams, drawings and technical data of other not yet described clandestine radios
(and related equipment) were found by readers and kindly sent to me. I saved this
information over the years, with the intention of compiling a follow-up of WftW Volume
4.
The already published amendments and new information were eventually, from 2015 onwards,
published in weekly issued parts as free to download ‘WftW Volume 4 Supplement’ chapters
on the WftW website.
The contents of the Supplement chapters is based on WftW Volume 4, having a similar
scope of information with the emphasis on technical details rather than history.
WftW Vol. 4 Clandestine Radio, Supplement Part 2 has been produced by popular demand,
as a full colour reprint incorporating all the later additions, covering the second
series of 100 chapters of the Supplement. With 202 pages and over 950 full colour
illustrations, drawings and circuit diagrams, the book match the size, layout, typesetting
and colour of the WftW Volume 1-4 series of books.
Without the generous support in the form of photos, drawings, circuit diagrams, scans,
and general encouragement from many individuals, museums and institutes, ‘WftW Volume
4 Supplement Pt. 1’ would definitely not have been possible.
It should be noted that all printable chapters of this book, including the later
chapters, are still free to download at www.wftw.nl
