The ARRL used to have a book that dealt with RTTY equipment. I believe the title was something along the lines of "Special Communications Techniques for the Radio Amateur". The 1960's and 1970's editions of this book had good info on the various Teletype and Creed machines, specifically on the Baudot models, and also some information on the ASCII models (realize that hams weren't allowed to use ASCII over the air until sometime in the 1980's). The pictures weren't top-notch (they were generally pretty poor halftones) but there were some. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
