Hmmm... Nothing jumps out at me. The outer encoding is triplets that have the values of 060, 061 or 063. It sure seems sparse.
I'm not any good at this sort of thing, it's just that the others were easy and you could at least see where the text and word breaks were. That and the fact that I've had to to read ASCII on an oscilloscope from raw signals back in the day...
