Radiotelegraph & Radiotelephone Codes, Prowords and Abbreviations

What started out as a minor Project in 1987, blew out like the national debt so with all this accumulated info, it seemed worthwhile to produce the first book, here now is the Latest Online Edition.
The sources and references have been many and varied and although the utmost care was taken, the Lists 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 was initially developed. The majority retain this influence but many have been modified and modernized to cover land and air applications. Technical terms have also varied as technology has changed however most abbreviations of the computer age have been omitted. These are specialist terms of that mode, not often encountered in telegraphy.
