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.
