(Ebook) Radiotelegraph and Radiotelephone Codes, Prowords and Abbreviations, Third Edition by John W. Alcorn ISBN 9781863844246, 1863844244

Book with operating signals used in wireless telegraphy (Morse code), Morse signalling by hand flags or arms, International Code of Signals, Police communications etc.What started out as a minor Project in 1987, blew out like the national debt so with all this accumulatedinfo, it seemed worthwhile to produce the first book, here now is the enlarged Third Edition.The sources and references have been many and varied and although the utmost care was taken, theLists are far from complete and may contain errors.The original Codes etc were designed principally for marine use as this was the field in which radio wasinitially developed. The majority retain this influence but many have been modified and modernised tocover land and air applications. Technical terms have also varied as technology has changed however mostabbreviations of the computer age have been omitted. These are specialist terms of that mode, not oftenencountered in telegraphy.Their number is huge and varied and computer books list them.Specialised Codes etc are not listed, eg. Armed Services, Civil Aviation, Weather Bureau, Commercialcodes etc as these run into many hundreds And are beyond our scope. There are exceptions of course,especially the Navy, where their codes etc formed part of the original listings. Obsolete and obscurecodes etc are included for historical interest but are never likely to be encountered in use.The lists are far from complete and it is requested that anyone who has information that will fill gaps orhas an obscure code that could be included please send it to me so the lists can he made more complete.Please quote the reference and date with a photocopy of the list.The Third Edition has extra material and additions to existing items, marked by an asterisk (*) in theContents. This includes new codes from the “International Code of Signals” 1987 - 1995.I thank everyone who has already supplied information and, in anticipation, anyone who might assist inthe future. I thank particularly the US Army and Navy Historical Branches, the ITU, Geneva, Mr. Brian Kelk ofCambridge, Engl., BT Archives, Royal Signals Museum, Blandford and many Internet sources andcontributors for their assistance. There are many others, both via Internet and other means have supplied orsourced information which might never have otherwise been recorded. Thanks to all of you.
