I just sent this and it bounced. If you get it twice, read it twice!!! Or
delete the extra one.

Here we go again:



I just read a fantastic book about the history of codes, not just the
amazingly interesting history of the Enigma, but the book goes way back to
early Egyptians sending secret, encoded messages. The book has tons of
examples of early codes and even a few secret messages for the reader to
decode. There is a very detailed history of the Enigma. I way recommend the
book for anyone who thinks such things are cool - considering this audience,
I expect that is most of us.

The Code Book.. The science of secrecy from Ancient Egypt to Quantum
Cryptography By Simon Singh

$14 as a Kindle book



Congrats to all who got Sandwich Is.  and Georgia   !!!! COOL  Now on to the
next one.

This is one fun DX group.

FWIW, I watched a very interesting PBS program today called "Dayton
Codebreakers".



Not sure if it will air again but you might want to look for it.  It is
about Joe Desch's (sp?) work with a vacuum tube machine using thyristors
that was able to crack the 4 wheel Enigma code.

Something Turings machine was just too slow to do.



They never exactly mentioned if he was a ham.... anyone know?
