127. Indicator group consists of five letters, of which the first two are dummies, the last three are indicator letters. The indicator group is put in as the first radio group. It does not get enciphered.
128. Dummy letters are chosen arbitrarily, and they must constantly change.
129. Indicator group letters are taken from the indicator group table printed on the Cipher Table (Cipher of the Day). Every day three different indicator groups are available. Always vary the order of the letters within the group. For example, the following indicator groups can be formed from ABH: ABH AHB BAH BHA HAB HBA
So, I am following along with the conversation and getting some decrypting practice :-). But I am having much trouble with the Triton message of May 20 above. In the interest of efficiency I'm using clear text.
What I gathered was, May 20/19, K-book table J, (XUE = 147, is Triton)
GX=PR UE=AI LV=EO ZA=UQ
P U A U R E I Q
Then Triton 2019 general base settings for May 20 HHF 20 C Beta II III V, S L V E, and 1/25 2/6 3/7 4/10 11/26 12/24 14/16 15/22 17/18 20/23, starting at D I W G.
REIQ becomes QYOT, reset for QYOT, beginning at the 3rd group of characters is gibber-jabber. What am I doing wrong? Cheers!
