    {SPOILERS} Secret Mystery Broadcasts

    I was playing around with the frequency decoder, and stumbled on 3 unlockable channels that feature a voice repeating a series of numbers in rotating sequence.

    As someone with a little experience in puzzles, I had no trouble decoding the first one ...

    The second was very similar and only slightly harder than the first ...

    However, the 3rd currently has me stumped. I sat with it for about 30 mins just now, and drew a blank. I'll try again later, when I have more time.

    A quick peek on the web seemed to indicate that I'm not alone on this last item.

    Anyone have any luck ?

    I know how to google, dude. I didn't bother reposting that item because it's unproven and obviously INCORRECT (wrong number of letters and no cypher pattern to link them).

    We need a cipher key (like the one I provided for sequence number 2 in my first post in this thread) that correctly maps an answer, and is independantly verifiable, otherwise it's just a useless guess that kiddies will blindly cut and paste as their own.

    A posted solution to sequence 3 must be PROVEABLE.

    Not much time today, but in the few minutes I had I've ruled out a "half-reverse", the "simple sliding scale" or a "reverse the words" key, and (I think) all permutations of two of those three together.

    There dont appear to be enough vowels in the raw message, so I think there's likely some alphabet rotation involved as one part of a compound cipher that was used. It's a start.

    The lack of spaces was a nice touch by the developers ... it adds to the difficulty.

    The third message is decoded by matching each number with its corresponding letter.
    [C T Z R Z P X A K D X I C H E B L R F P G K C J Q E M D U H]

    Then you need to use the Atbash Cipher so that A is submitted for Z, Y for B, X for C, etc. Then you will get
    [X G A I A K C Z P W C R X S V Y O I U K T P X Q J V N W F S]

    Then all you gotta do is use the Vigenere Cipher while using the keyword "SCARECROW" to eventually get the final result

    You should really put your source for your find here since it is not your own.....

    Thanks for the nudge, Zombie-4.

    Nice to see a solution finally appear. I'm normally pretty decent with most types of puzzles, but that last one stumped me. Anyway, I'm in the middle of a 2nd playthough of Skyrim. As soon as I'm done with that, I'll probably return to BAC for a bit, doublecheck the cypher to verify it, and then see if I can get a bit further along in the post-game challenges.

    Cheers.
