Thank you very much for the article Paul
I have resend your message to the MoonBounce reflector. Most of the hams are
using digital modes in Earth-Moon-Earth
communications and recently new modes as QRA64 have been developed.
Unfortunately only a very small fraction
can really understand what is all this stuff about (me not included there) :-)
You can only say to really understand something, when you are able to explain
it to your Grandma ;-)

Asunto: 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.
