Here's a transcription of Mykl Atrum's recording of the FFUP signal- the new one you get when you look at it from the end that points to Merope.
as little interpretation as possible- I tried to just write what I heard as the different sounds in the signal. Anyone who has heard it knows it's a crunchier fuzzier signal than the others, with echo, reverb, wobbly frequency shifts etc. I'm sure other people have other takes on it and I encourage people to post them.

sections = sounds after each howl
. = the fast dits before each set of three longer tones
h = high tone
l = low tone
# = rising flangey sounding chirp tone, as heard after the 4th triplet tone in the file
section 1 - 4 has 1 # sound per section
section 5 has 3 of them

I made two quick conversion of the High/Lows to Octal and Decimal.

As others have suggested, the H=0 and L=1 seem far more reasonable as all the 'after #' numbers are fractions of each other.
We have 1000, 250, 200 and 125. These relate to each other as 1, 1/4, 1/5 and 1/8.
There are no exceptions to this pattern. It looks quite solid.
Edit: DigiDan Nijaed me on the good part of the decoding. Good work.
