My "ground settings" are the same. In other words, this part is the same:

B | II VI VIII | 25 24 05 | AS BG CZ DK FM HU IT NP OQ RW

My indicators, if you looked at standard Ubootwaffe procedure, were buried in the first and second (and last two) groups, with padding applied. The first two groups and last two groups are QBWL DTOQ. Per standard procedure, the first character of the first group, and the last character of the second group, are "padding" that can be ignored, giving a cipher indicator of BWL DTO. Set the wheels to BWL, then type in DTO to get the message setting.

For a real Ubootwaffe message I would have enciphered the first two groups with a bigram table, but I don't have one handy, so I went easy on you:)

The first line is a preamble with the entity the message is for (you), the time sent, the date sent, and the serial number of the message, follow by the number of groups.

The last "SK" is a Morse prosign for "End of Schedule".

Yesterday reading the link you provided to those procedures I noticed the repeat of same two groups in the begining and at the end. So I had a clue that you've changed the kennengrupen but could not figure out what they were. Probably due to late night time here :haha: My bad, sleepy head ain't working right when it comes to figuring out things :) I am going to study the procedure and hopefully will use it later.

Till now I was using the Enigma codebook tool which I find the way too easy already :salute:

P.S. Could I have another message to crack, please ? :D

My original intention in this thread was to promote the use of Morse Code and the use of Enigma as BdU and the U-Boats did to communicate with each other.

I think a few "Ground Rules" apply, I do not mean to offend anybody but I would like too simulate the methods used as accurately as possible.

This I think is how it was done.

1. Enigma Code Book reading for the day/month/year set into Enigma.
2. Message entered.
3. Resultant characters (transmitted in Morse) ie .-- ...-- ----- .----

Recieve.

1. Recieved transmitted characters (in Morse), as BdU/The U-Boats did, entered into Enigma.
2. Message read from Enigma.

Couple of things to note:

1. If we wanted to *REALLY* be authentic, we'd be trading audio files. There are several free Morse encoders and decoders available. One called "EhoCW" allows you to record and play back your Morse as a .WAV or .MP3 audio file.

2. Trying to read Morse like this "-- --- .-. ... ." is kind of insane.

3. Klt_KUrtz, standard Kriegsmarine procedures for non-kurzsignale or wetterkurzsignale requires a preamble with the following format:
RECIPIENT TIME/DATE/MSG_NR GROUPS
Then, you put your two indicator groups at the head and tail of the message. If you are using a 3 rotor Enigma, you add a 'padding' character to the beginning of the first group, and a padding character to the end of the second group so that they are both 4 characters long. For a 4 rotor enigma, you don't add any padding. For our purposes, a "broadcast" message to all boats at sea could have a recipient of "VVV", for example.

Bite your tongue.

Morse is *THE* most perfect form of communication. It is media independent: You can send it via audio, by keying an RF carrier on and off, or a light, or you can even wiggle your arse in Morse. You can't do that with teletype, or even voice.

It's also a damned fine way to communicate if you are ever paralyzed. If you have *ANY* voluntary muscle control at all, you can use it to send Morse, even if it's by blinking an eye, wiggling a toe, or even modulating your breath.

Not only that, but it's a universal language also. I can and have had conversations with people who didn't speak English because Morse Q signals and prosigns are the same in every language.

In short, Morse rocks :rock:

And I'm not just saying that because I'm brain damaged from my time as a ditty bopper.

Agreed morse code rocks, but still why navy used the flagmans for signals when they could transmit anything by morse ? :hmmm:

[Puster Bill]

Agreed morse code rocks, but still why navy used the flagmans for signals when they could transmit anything by morse ? :hmmm:

Flag signals were invented *BEFORE* Morse, and military organizations tend to conservative and cling to things that have worked well in the past. Though I would point out that the use of Morse via Aldis lamp pretty much supplanted semaphore in the navies of the World from the late 19th Century onwards.

Morse via lamp has disadvantages, also. First, it's directional, where conventional signal flags aren't (semaphore is semi-directional). There can be times when lighting conditions favor one over the other. And, in the final analysis, flag signals and semaphore work even if there is no power on a ship, something to consider when the possibility of battle damage is very real.

Now, you *CAN* send Morse via flag, but like I said military organizations tend to be traditional and keep what works, and conventional flag signals and semaphore work well enough.

A link to some Morse training software programs (some free, others not) for those interested:

http://ac6v.com/morseprograms.htm#CWT

And an excellent primer on Morse and how and why you should learn it:

http://www.qsl.net/n9bor/images/The%20Art%20&%20Skill%20of%20Radio-Telegraphy%203rd%20edition%204-02.pdf

Though I do have *ONE* small problem with it: The advice about advancing on to hearing "words" instead of individual letters is correct for receiving plaintext, but useless for receiving enciphered messages for the obvious reasons. It's perfectly fine for ham radio usage, however.

Couldn't agree more. I'm just lazy.

[RoaldLarsen]

Agreed morse code rocks, but still why navy used the flagmans for signals when they could transmit anything by morse ? :hmmm:
Here are a few other advantages of signal flags over Morse not already mentioned by others:

Ease of use: Signal flags are easier to learn (at least for some people) or to be understood by the untrained with the help of a reference.

Signal flags can be used to transmit an ongoing state: I am attacking a submarine; I have a plague on board.

The non-directional nature of the flags, compared to lamp, means that it is easier to send a message simultaneously to multiple recipients. (Like from a flagshp to all ships in a flotilla or convoy.)

Signal security: compared to Morse R/F transmission, and in some conditions signal lamp, flag signals are less likely to be interecepted by the enemy. An intercepted message may be decoded. The mere act of making a R/F transmission gives away your existence, and possibly your position.

[Puster Bill]

Dude, I'm lazier: I've copied Morse in my sleep.

I will say this, though: I had a pretty good incentive to learn Morse when I went to Fort Devens: If I didn't learn it fast enough, the Army would get to pick what school I went to. I could have ended up in the Infantry, or shoveling out the kennels for the K-9 units or something.

[Puster Bill]

Not too bad.

That's essentially how I learned it, by the way, except that they started us out at 6 words per minute instead of 5.

You learned all the characters at 6 wpm, and the computer kept track of how well you were doing. When you got up to a certain level of competence, it would bump you up to the next highest speed.

If you were having trouble (many people hit a 'plateau' between 10 and 15 WPM), often the instructor would have you copy at a higher speed for a while, then bring you back down because the code sounds slower that way.

Just remember to relax and copy behind the code.

[Contact]

Yeah I already noticed, that tension ain't bringing me luck. I have to relax for quicker reaction in realizing the codes and entering them by keyboard.
Anyway most of the time it feels like brain stretching thing :woot:

[Puster Bill]

Don't burn yourself out on it, either. Do maybe 15 or 20 minutes, then walk away for a while. I didn't have that option, although they did give us relatively frequent breaks while we were learning.

Pretty soon you'll get the hang of it. Once you get all or most of the code under your belt, start listening on the ham radio bands for some Morse. Some of us send slow enough that you'll be able to copy. It's fun, and who knows, maybe you can get your license* and we can set up a scheduled contact (though we can't pass encrypted traffic).

*You don't need to know Morse to get a ham radio license in most countries these days, don't know the regulations where you are.

[Contact]

Yes, I do my breaks too, but I noticed that first 2 minutes I'm doing fine with now 6 charachters. After this time I'm begining to loose focus and usually hit stop and try again later..

[Puster Bill]

If you are getting 2 minutes of good solid copy with 6 characters, then it's probably time to move on to learning more characters.

Just out of curiosity, does Lithuanian have "extended" characters beyond the normal Roman alphabet? I learned the extra 4 characters needed for Russian Cyrillic, and promptly forgot them because I never used them after Morse school.

Nah, I'm pushing myself to complete whole 5 min test with no less than 95% accuracy. Since I believe it will be easier in the future to make less mistakes with more characters later. When time is not a pressure I'm taking time enyoing the lessons my way u know :)

As far as I can tell the message coming in in SH3 sounds like:

Which means:

No wait!!

What that is is a preamble for the actual message.

I'm really only starting to look into enigma, but given all the possible setups, how was it possible for both parties to know the 'shared key' at any given time? Was it already layed out in some sort of handbook that guaranteed both sender and receiver would be the same on a given date, or was the key somehow transmitted with the message?

This is a little beside the subject here but when I went through morse code training we had a former WW2 navigator/radio operator as an instructor. During endless hours of listening and transmitting on the waves he had developed a special sense for the rhytm of the various morse letters. Instead of perceiving these as dots and lines each letter had taken on its own expression. For example: A was tit-a, B was be-bib-bib-bib, C was Ce-ti-ce-tit......and so on. As you see each letter then contained the actual letter in this constellation. Further it was very easy for us newcomers to grab these dot/line constellations - and remember them. Actually, we didn't remember at all - it just sneaked in without any real plugging. The real beauty of this system was that the rhytm of the various letters transformed directly to the morsing finger. Transmitting was actually easier to learn than receiving. In this way we, in general, needed only 12 hours of instruction to be able to transmit/receive 120 signs per minute. Which was the aim.
