I’m of two minds about the “e’s” in the Morse code. Either they were a convenient way to get the code to space properly on the copper sheets or they are significant.
I recently got the idea that maybe they aren’t E’s at all but markers for specific letters that perhaps would spell something useful. The idea is that perhaps each E was under or above a significant letter and we would be able to take those letters and use them to spell out a message. This seemed to be a simple and easy way to impart needed information. In practice though, I didn’t find much. The E’s are all on the ends of the words and don’t seem to clearly indicate useful letters.
It was an interesting idea but did not work.
Going along with the ‘digital interpretation’ possibility, I’ve tried a few things, but didn’t get far at all with them.
1) Writing out the entire message (e.g. ‘EEVIRTUALLYE/EEEEEEINVISIBLE’) or (‘DIGE TALEEE/INTERPRETATI U’), then translating into Morse code. Then trying to get Morse numbers out of the text. Also tried getting numbers reading the Morse backwards.
2) Counting the ‘E’s; assigning numbers to the respective collections; adding amounts on either side of the break; adding all the ‘E’s together, etc.
3) Assigning letters to the respective numbers or sums of numbers; trying to anagram them, etc.
I have a feeling the ‘E’s are significant as well, but it’s been difficult to extract any meaning.
He’s so fixated on grids and matrices, Sanborn that is. There are 25 E’s (5×5) and 81 Morse letters (9×9) but I’ve never found a way to use that for anything.
