>>> There is no reason to encrypt.  Coded is good enough.

Correct, although I think it's more a question of semantics than anything 
else.  "Encryption" in the WWII era was just another term for the process of 
messages being encoded.  It's only been since the start of the digital age 
that it has started to mean something additional or different done to the 
transport stream, rather than the plaintext message content.

As was the point of my earlier message, who among us has any idea at all 
what that quoted text said?

On the face of it, there are fourteen lines of two-letter-and/or-numeral 
groups (which can be anything from a simple cipher to a highly convoluted 
code, or a pointer to pre-agreed words or phrases--that's encryption), with 
each character apparently rendered in standard phonetic fashion.  The latter 
is a humanly-implementable form of error correction, if you will; lose a few 
individual symbols and you can still reconstruct the whole thing with a high 
degree of confidence.  But it's still encrypted--literally meaning, 
hidden--in the sense that not one of us knows or will ever figure out what 
it MEANS.  As David says, that is certainly good enough.
