[ARC5] Zero Beat Question

[Richard Knoppow]

      I am always glad to see questions that are relatively elementary 
of the sort that one thinks "why, everybody knows that", but when I try 
to explain it decide that perhaps its not obvious at all. In fact, 
sometimes I discover _I_ don't really understand something I thought I 
did.  I think sometimes older books had better explanations than newer 
ones, perhaps because there was less to cover.  A good source is Pete 
Millet's site
http://tubebooks.org  this has all sorts of stuff on it including 
several ARRL handbooks and some good fairly elementary electronic theory 
books. Do not sell the old ARRL handbooks short; their introductory 
theory chapters are usually well written and are aimed at those who want 
and need practical information.  The "Radio Handbook" edited by William 
I. Orr is also excellent. Modern radios with all their digital functions 
have become rather un-intuitive so it is sometimes enlightening to go 
back and see how all this was done with analog.  Never ignore the 
fundamentals.
