Alright CMDRS,
3. The message, if there is any, is long! I caught 56mins and the patterns did not repeat. You will see there are many pauses between groups, up to 2-3mins.
Maybe it does repeat something but not the same thing..
Like a Fibonacci sequence or something, each group looks different but it builds from the last group, maybe you only have to decode the first 5 or so and then all the rest can be worked out from that?
