The textbooks I know of are three by E. C. Snelling, and are referenced in my tutorial. KC9GLI, then a prof at U of Chicago, found a copy of the first one in the third basement of the engineering library and loaned it to me. I have the second one. I've never seen the third, but I've seen it for $300 used on the net. He worked for one of those major EU companies, and his books were considered the bible. 73, Jim K9YC _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
