Hello everyone
First a big Thank you to Mauser for all his hard work on the "advanced" procedure( and any one else not mentioned)
attached are bigram tables and M4 key sheets in zip files for 2018 encoded correspondents. hopefully the forum will adopt them 
there are three M4 procedures to the best of my knowledge
- M4 TRITON
- M4 TRITON[FLK]
- M4 TRITON[ADV]
I propose that the key sheets can be used for all three procedures, but not the bigram tables.
the first two use 12 bigram tables( January to December) the third use 10 bigram tables labelled A to J.
Mauser uploaded a file to cloud, along with the procedures etc, named "A9R1mitl3l_17f8hi_2j8.pdf" this has the 10 bigram tables used in the practice procedure. Mauser also posted "bigrams 2018" this is a different set of 10 tables labelled A to J. we(someone) needs to pick one.
if other members could look over the M4 and M3 sheets for spelling errors, duplication etc, one checking one's own work is not a good idea.
i have had issues with attachments before, so any problems, please post or email me directly
regards
OIK

Hey, thanks for giving us a 2018 keysheet post.
I think M4 procedures should be divised into M4 Triton - M4 Triton [FLK]
and M4 [ADV] which is either Triton or Hyrda (finding out which is which, is part of the fun I think).
To use the ADV procedure, all the docs posted by mauser in the 2017 Keysheet post are needed.
I am in favor of using the above linked tables and keysheets for M4 Triton and M4 Triton [FLK] but for the ADV proc. the "mauser pack" as I call it, is absolutely necessary.

Is there a difference between M4 and M4[FLK] any longer?? I think you really only have the two different types for the M4, either the basic procedure [EWCG2018TRITON] and advanced [EWCG2018ADV]. Given that, is there a need to have different sets of codesheets for each?? I would rather have ONE set of Triton codesheets that could be used with either procedure. Maybe the other set of sheets could be for a different radio net, like THETIS ... wasn't that the net used for tactical training?? And just have two extra bigram tables for November and December, but let Januart use the A table, February use the B table, etc. The more versions of the files to keep straight, the more error prone this will be.

I must say I really like the idea of having a third (or more) network to chose from in the ADV procedure, and it is true that two sets of Triton's might induce mistakes.
What do the admins think of this?
I understand your concern about the number of files needed but in this paricular case, I think it would be more confusing.
What I do is create different folders on my PC named after the procedures and put every file needed in them, even if it means having some files in double.
It helps me get the correct thing right away

It helps me get the correct thing right away I can see that, although the same approach would work for the different sets of Triton code keys too. I guess I'm still a little "old school"... I actually have been printing out the various sheets, or in most cases with the codesheets actually importing the data into Excel and then printing out reformatted versions that are easier for my poor brain to handle (I combine the inner and outer settings onto a single sheet, for example, and make the Bigram tables in larger print so my eyes aren't fighting such small print). I can certainly handle having two variations of Bigram tables, but it seems it could be as much a source of mistakes as having the second set of Triton codes. Just another aspect to remind us to be careful in performing the procedures. I'm going to redo my reformatted versions to include those message tags, like [EWCG2008ADV], to help me keep those straight. |

Being a real lazy head, I zoom in the pdf and use the edge of the (Enigma simulator's) box as a ruler in order to follow the right line.

Keep in mind TRITON was used for deep water North Atlantic etc. operations. HYDRA is for Home waters. There was a different network for the Mediterranean.

And just have two extra bigram tables for November and December, but let Januart use the A table, February use the B table, etc. The more versions of the files to keep straight, the more error prone this will be. Bruce Culp (Admin at EWCG website) and I discussed this several months ago. We thought that the one set of TRITON codesheets would serve those just getting started and we'd call them the Basic version. Still Four Letter Key since M4 was 4 letter key to begin with historically. The Advanced TRITON/HYDRA sheets include the requirement to use the Kenngruppennbuch (K-Book) and the separate Doppelbuchstabentauschtafel (try saying that 5 times fast ). So, instead of using a Key identifier as in the earlier format, we grab a Kenngruppe, as done historically. Also, instead of using the same bigram table for an entire month, the K-Book has a Table Plan (Tauschtafelplan) just like the real K-Book that requires using a different bigram table for a given day. So if you want realism, you use the 10 tables. The system was designed around either 9 or 10 tables. Since that varied from radio net to radio net, Bruce and I decided to fix the bigram tables to 10 and that would cover roughly 95% of the way things were done. Bottom line was this, we wanted to create a clean setup for those that wanted to use the historically accurate procedure, which is more complicated, and a basic procedure that was based on the early website and forum with the exception of the 4 letter key correction to the M4 procedure. Last year, lpaseen created the Basic TRITON code sheets, so I avoided stepping on toes for the basic procedure. I am not adverse to using the TRITON codesheets (Schlüsseltafeln M – Allgemein and Offizier) on the website, since you will likely want the HYDRA versions as well. As soon as I complete translating the Satzbuch for the Short Message Procedure, you will have almost everything you need in your simulated U-boat. I will be starting a series based on the KTB's of various war patrols. Kind of a story and you get to decode and encrypt traffic. And if you follow the story lines, you will send HYDRA messages early in the patrol before you start sending and receiving TRITON messages. You will get to create Weather messages and create and decode Kurzsignale messages. I was extremely fortunate that a generous benefactor had scans of several of these books to translate and use. Folks that have the few remaining copies are not interested in scanning them generally because they can get many hundred thousand dollars for them at auction. And after the Short Signal Procedure, there is one more encryption procedure to publish, that being the R.H.V. This was used if you either did not have an Enigma on board or it was broken. With the RHV, you'll have 100%. After I get these last few things done, I can basically sit back and have some fun. Mauser sends. |
