CQ: Calling all CW mail list subscribers!
I know some of you are subscribed to QTH net's Morse Code reflector
which is devoted to collecting keys, so pardon the duplicate post.
Sometimes very interesting history comes up and I thought the readers
of this group would be interested in the articles that W1TP, Tom has
posted on the Internet.

Subject: [MorseCode] U-Boat Communications & Enigma Talk:
To: MorseCode <morsecode at mailman.qth.net>
Several people have mentioned that they were not able to get to my
talk at the Deerfield Hamfest and asked me to make it available on my
websites.
I have done this but it will require some interesting computer work on
your part to be able to view and hear it.
The talk is entitled: MILITARY COMMUNICATIONS DURING WW-II AND THE ENIGMA:
It is a densely illustrated presentation with 160 photographs and
diagrams that cover the following topics:
German U-Boats in the North Atlantic and the statistics on boats sunk
and U-Boat casualties.
Diving on sunken U-Boats.
Grand Admiral Karl Donitz, Fuhrer of U-Boats and his unusual approach
to guiding the U-Boat Wolf Packs.
The amazing 1,000,000Watt Very Low Frequency transmitter called
'Goliath' that he used to communicate with the U-Boats.
U-Boat Radio Rooms, radio transmitters, and radio operators.
U-boat antenna radiation patterns at different frequencies.
British direction finding technology and traffic analysis of U-Boat
communications.
Typical radio intercepts by British Y-service listeners.
The diagram of all of the important German radio nets as derived from
intercepts and traffic analysis.
The German Navy 4-rotor ENIGMA as used on the U-Boats and my German
Navy ENIGMA as shown in a book.
The invention and history of the ENIGMA.
How the ENIGMA works and how the 'day's keys' are set up.
How the Poles were the first to figure out the wiring of the ENIGMA
and to decipher ENIGMA messages.
How they gave this information and their hand-made models of the
ENIGMA to the British when Poland was invaded by Germany.
How the British captured ENIGMA code books from submarines, weather
ships, and other vessels with photos of the captures.
A plan to have a British crew crash a British flown German Bomber into
the English Channel and have the crew rescued by a German Patrol boat
and kill the
crew of the patrol boat to capture the ENIGMA and code books.
Many pictures of Bletchley Park and the radio intercept receivers,
work rooms, deciphering bombes, and Turing's Colossus deciphering
machines.
Samples of important ENIGMA coded messages that were deciphered during the war.
Hunting for ENIGMAS today: The Allied Edict to destroy all ENIGMAS
with photographic examples and my own successes in finding intact
ENIGMAS.
Oral History interviews with German ENIGMA operators and repairmen.
The German Lake where ENIGMAS and end-of-war high technology
ultra-secret cipher machines were dumped with underwater views of some
of them.
Two ENIGMAS salvaged after 50 years underwater in a U-Boat.
Distributed processing using thousands of home computers to decipher
original ENIGMA messages recorded during WW-II.
A contest to decipher ENIGMA messages yourself given only some parts
of the day's key.
The American M-209 cipher machine and the Russian ENIGMA codenamed "FIALKA".
German WW-II Radio Equipment for sale at the Friedrichshafen Hamfest.
If that is not enough, you can always buy a copy of my The Story of
the ENIGMA: History, Technology, and Deciphering - CD from Tom French,
W1IMQ at http://www.artifaxbooks.com As you can see from this
descriptive website http://w1tp.com/ecds.htm, it has a new 60-item
Table of Contents that includes:
The entire history of the Enigma and associated models.
The Technology of the Enigma including disassemblies and wiring diagrams.
The Deciphering of the Enigma including many examples of deciphered messages.
5 videos including the ENIGMA, M-209, NEMA, and FIALKA in action.
7 books and manuals
4 software simulator programs.
2 huge archival databases.
...and a great deal of additional material.
To access my talk and the associated audio .mp3 file, you may download
them from my website.
Let me first explain the problems with these recordings:
First, the promised computer projector and screen did not arrive at
the lecture hall so I had to find a second projector and make a screen
out of a white table turned on it's side. This led to some confusion
that can be heard at the beginning of the talk. In addition, the
volunteer examiner's session for ham licensing was to come after my
talk but I was informed about 5 minutes before the end of the talk
that I had to stop NOW ! So... there are additional slides that I was
not able to narrate but which are included in the show. In addition
to these problems, the narration of every slide was cut off about 10
seconds into the slide. As a backup, I made a free-running audio
recording in .mp3 format of the entire presentation which you can
download and you can manually step through the slide show as you
listen to the narration.
Here is how I suggest you proceed IF you have a fast internet connection:
(I do not have a fast connection since I am in a very remote part of
Vermont with no cable, DSL, or cell phone.)
First, DOWNLOAD: http://w1tp.com/temp/n7web.mp3
This is the entire free-running 9MB .mp3 narration file of the entire
talk up to the point where I was told to STOP !
Then DOWNLOAD the HUGE 67MB PowerPoint presentation:
http://w1tp.com/temp/n7web.ppt
Start the PowerPoint presentation photos on your computer so you can
step forward through each photo manually.
Start the narration .mp3 file and use the narration to help you guess
where to step to the next slide.
(I tried this and it is pretty self evident when I have shown a new slide.)
I hope this will work for you.
IF you would like to view the presentations that I gave at the 2007
AWA Conference, here are the PowerPoint files and the associated MS
Word outlines that accompanied them. Unfortunately, I did not make
any audio recordings of these presentations:

for the 2007 AWA Key and Telegraph Seminar. (16MB)
This includes an introduction, Dayton and Friedrichshafen reports,
Clark & Phelps registers, etc.
