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.
