Still can't figure any of it out. But while watching the morse frame in its context I started wondering, "what if the Q are not supposed to be there?". If you split the morse at the double dash, most of the word make some sort of sense. Possibly confirmation bias, I'll post it one of the many iterations:
:
--. -.. .--. -- .- --- .--- / -- .- -.- / -- .- -.-. / -. .. -.-. -.- .--. --.- .--. / -.. --- / -- .- -.- --- / --- - -

I'm really, really terrible at morse, maybe someone more expert could figure something out. Just a thought.
Anyway I'm still going through every frame, wish I could make sense of some of it though.
PS: tried running them through Atbash too, nothing relevant I fear. We may have to spear head the mudokan substitution first since it's the most visible message and probably the one meant to be found first. I'm seriously out of ideas though, where the big'guns at? :P
