Hello Everyone
attached are two files, The RHV tables and the RHV procedure. you still need the K-book from the advanced procedures.
The procedure is a work in progress, so any typos spotted or suggestions to change text are more than welcomed.
So now we have three radio nets, Hydra, Triton and RHV from the advanced procedures.
hope you enjoy this
regards

Hey, Thanks for your explanations, they were quite clear.
This does take some time...and it is so easy to make a mistake..
Well, I hope I did not make too many of them in this message and that it is still readable.
I did use the tag ADV because I wanted to hide the fact that I was using RHV.....Darn!!...now I've said it!!!

Those are outstanding! I wonder what bigram tables you used since I have an RHV app. If they are different I'll have to transpose the ones you are using into the text files the app uses. Anyway, excellent instructions, and excellent setup. Keep in mind, RHV is for any net including Triton and Hydra. It was there in the event you busted your Enigma, forgot to store enough batteries and ran what you had dry. Some of the Schnellboots and surface vessels used RHV since they might not be issued an Enigma.

I have tried with the Triton CodeSheets which gives me a start position of SUSS + TEMV = IPPZ which does not decode the message Since this post is about RHV, I tried it also RXU is on row 10 and (on the wierd page named Spalte681 in the Kbook) TEM is on row 14 in the "Tauschtafelweiser", row 10 and column 14 gives me 13-22-6-8 as Birgam tables. In the "Zahlenreihentafel", row 13 gives me 2 13 3 9 11 1 10 4 8 12 7 16 14 5 15 6 as column order. However, none of this gives out clear text. Any help on what went wrong will be appreciated

Any help on what went wrong will be appreciated Hi Arnaud
now don't get mad, its not an [ADV] procedure, its a [FLK].
we just dropped from the [FLK] from the header(so I was lead to believe)
but on a high note, I am working on March's challenge and it will involve all procedures

Mwahaha, of course, it was right there in front of me. What an idiot I have been. Since this was a post about RHV, I wrongfully assumed it would be RHV so I immediately jumped to Kbook and all that goes with it. For some reason, I always forget about the header...when writing a message I often (almost) forget to put a header in it. Thanks. PS: technician275 Yes, please, by all means, any link is appreciated.

Just something I picked up in the last few days about sfF. The Germans sent a number of random messages with nothing of importance in them. Much of it was random letters. To let the u boat crews know not to waste their time decoding it, they used an entry from table 681 for the first group. So once the operator decoded the bigrams he would see the first group was from 681, therefore not assigned to any radio net and stop any further effort on it. Needless to say, once the allies had a copy of a Kbook, they caught on and didn’t bother working on these types of traffic.

Hi again technician275, What did you use for Table A in your excellent RHV procedure description? Can you please post? Thanks. (BTW, I posted photos and a blurb of my Open Enigma build in Arduino Engima's thread: enigmaworldcodegroup.freeforums.net/thread/216/ if you are still interested).

Not sure what you mean by table A, while doing the procedure I used excel spread sheets to make the tables, I hope this helps. as for your link, that stuff is great but a lot over my head LOL.

Tafel A (Table A)
"For the purpose of this exercise we select the following
Column 221 row 6 = JYX
Column 566 row 12 = MMS
The row numbers are very important and will be needed in subsequent steps
The date we will use is May 4th, and according to the K-book that is bigram Tafel A.
The (L) and (Z) are random dummy letters to aid the bigram transposition
L J YX
MMSZ
LJXY and MMSZ now get transposed as per M4 standard procedures
LM=BN JM=UK YS=LR XZ=XZ
This results in our message key group
BNUK LRXZ "
Not a big deal, I get the method. Just curious about the bigram table used.

Just curious about the bigram table used. Hello
There are TEN separate bigram associated with the K-book labelled A to J, right now I cant remember who generated them, there appears to be none for 2019 K-book.
the May challenge I had planned is taking longer then expected so it will be in June's challenge.
Hope this helps
