Hi EbNaut LF= ,

With material from K3RWR and K3SIW I started a page about using
EbNaut on LF. This is an attempt to help people who are interested
in using EbNaut on LF but having problems understanding all the
complexities.

http://www.n1bug.com/lfmf/ebnaut/index.shtml

I hope I will be able to put much more information there. If anyone
would like to contribute articles, diagrams, photos etc. it will be
very much=C2=A0 appreciated.

I will also try to put some links to other web sites, pages, etc.
but I don't promise to maintain those as things disappear or URLs
change. :-)

Speaking only for myself, I am still struggling to understand
hardware setups. So far, the only EbNaut hardware setup I understand
well enough to build it is K3RWR. All the others still going over my
feeble head. ;-)

73,
Paul
