                Book "Direct Conversation Technique for Radio Amateurs" was published in Moscow in 1990 year. The book was 
                compliance of two early published two books- "Direct Conversation 
                Transceivers" (the book was published in 1984) and "Direct 
                Conversation Receivers" (the book was published in 1981). 
                Lots new stuff there was added to the "Direct Conversation 
                Technique for Radio Amateurs." 
                The book was very popular among radio amateurs of the USSR and 
                then ex- USSR countries. I can say that the book was a Bible Book 
                for Direct Conversation Technique. The 
                book was published in 200, 000 copies so lots amateurs could have 
                access to the book. The book gave way to amateur radio for many 
                beginner hams. As well the book inspired experiments with Direct 
                Conversation Technique.  
                
              I have all three books written by RA3AAE. Lots hours 
                were spending with soldering iron and one of the books. The book 
                was found in the internet at public domain (I really do not remember 
                where I found it) and now the book available at ANTENTOP site. 
                Such books cannot be disappeared. It should be serve 
                for Radio Amateurs for long years.

              The book was published in Russian. I cannot find the 
                English translation of the book.
