Agree with most of this - out of rep, tho
Please remember as you read this post - this is my opinion, and I project it as such. I have no more authority on this than anyone - I'm just sharing my thoughts.
I do think there's a good chance of a specific location being important. But... I know, I know: where!? I wish I knew! But that Morse is more than just something interesting - it's a clue in and of itself I think.
I personally think the Mayan theory is, although nice, a complete dead end.
I also believe the purrs to be a dead end - there's nothing there - not a single test focused on the purrs has reliably produced the same result in all cases for all CMDRs under the same conditions. I skip all posts mentioning purrs now.
I think all attempts to partner the UA with any other type of cargo in free space or in a hold are also dead ends. And no justification I've read compels me to think otherwise.
I think triangulation is a dead end - they're found in convoys - who knows how far the convoy(s) are 'supposed' to have travelled by the time they spawn for you?
The 'let it expire' is a dead end - they have, on more than one occasion, and nothing has happened.
Also, all the fanciful ideas about plague carrying/cure neglects the morse, and therefore human, angle (unless a conspiracy theory involving CIEP or INRA or whatever is entertained - which I have not ruled out in my own head).
The hidden VID8 Morse thing - that's a dead end. Too nebulous, not corroborated by enough people.
SS1 was not carrying a UA. Simple as. It was an assassination job, possibly by the new Pres - possibly by the DW or whatever. Whomever is the culprit, I have a strong suspicion they are also the puppetmaster behind the Emperor's assassination. There's wheels within wheels in that story I think, and there might be a UA connection, but that's not what we're supposed to discover if there is.
The UA doesn't cause a misjump. It would have happened by now.
Pretty much every method of interaction at our disposal has been tried - in terms of what our ships can do - and nothing. So that's a dead end.
My own personal scepticism about the merits of listening to him aside - Kerrash reckons the feeling is that there are 'enough clues' out there already. Galnet and licensed fiction are our primary sources for this - so there must be something in these that links to the UA or, more likely, links to some other event or story that is linked to the UA.
After struggling with the narrative style a lot, I've started on reading 'And Here the Wheel' - because that's also been hinted at by Kerrash (damn you), and there's nothing else I can do at the moment. There are already some links between one or two Galnets and the contents of this book - suggesting a strong link to the events in that book and contemporary events in-game.
Like everything else it'll probably end up being a dead end(tm) - but will see.
Remember - if I've just rubbished your idea - it's just my opinion; and it certainly isn't personal. As far as I'm concerned, all of you are awesome(tm).
