Greetings Holger!   
      
    EV>> A copy of The Radio Amateur's Hand Book 1922 by A. Frederick Collins   
    EV>> is at their web site.   
      
    EV>> It isn't current, but it is interesting to read about how to build   
    EV>> a Spark Transmitter.   
      
    HG> Are you shure that 1922 is correct. I own a 1926 edition of "The   
    HG> Radio Amateurs Handbook" "First edition" that was included with the   
    HG> purchase of the 80th anniversary of ARRL handbook.   
      
   A. Frederick Collins authored the 1922 Radio Amateur's Handbook, it isn't   
   by any means the Radio Ameateur's Handbook of today or even 1926. Merely a   
   history of radio up to 1922.   
      
   Archie Frederick Collins (1869-1952) was a prolific inventor and author of   
   many technical and popular works on radio, science and technology. We are   
   indebted to him for this remarkable view of Amateur Radio technology in   
   the early 1900s. The Radio Amateur's Hand Book, was reprinted in 2008 and   
   is available free online from Forgotten Books, and in paperback at   
      
   Amazon.com, 236 p, $9.01.   
      
    HG> Please note: That 1926 Handbook was published by ARRL, not by some   
    HG> A. Frederick Collins.   
      
   Modern readers need to know this is not the ARRL Handbook for Radio   
   Communications and it was not written by Art Collins of Collins Radio. It   
   is actually a collection of early Amateur Radio information and projects,   
   complete with how-to-build-it information. While the content may not have   
   been forward-looking for 1922, having several stages of technical history   
   compressed into one volume is enlightening and entertaining for today's   
   readers.   
      
      
       Have a day!
