Jon, search on the web for koch method.  I think it is something like
g4fon or something like that.  You use the computer to learn code.
Also, there is some tapes that you can get from Handiham.  I don't think
there is a charge either.  Call Handiham and ask about the Gordon Wess
code tapes.  I use the g4fon and the Gordon Wess an d while it is hard,
I am progressing slowly.  I too am like you in that I know I don't have
to learn it but I still am.  If I can be of farther help, please feel
free to contact me.
