Hi Paul, thank you for the effort put into his. I found it "easy reading"
and very informative. It filled in a lot of the areas where I have "read the
words" previously but often not fully understood the significance. It
probably deserves wider circulation amongst the amateur community where it
has the power to dispel some of the "smoke and mirrors" magic of "digital".

Subject: LF: Article on forward error correction
I wrote a non-mathematical introductory article about how
forward error correction works.
There's a lot of material on the web about FEC but most
of it is very technical and tends to concentrate on one or
another particular coding scheme. I couldn't find anything
that demonstrates and really explains in simple terms the
essential principle of it.
So I thought I'd try to write something, perhaps to see if
I can understand it myself.
The article should appeal to anyone who's wondered how 'coding'
a message, which increases its bandwidth and reduces its S/N,
can actually lead to greatly improved communications.

Whether I've succeeded or not, the reader will have to judge.
