The people who developed it did not call it an encryption method. (For the
simple reason that no cryptology is involved.)

Tsk, tsk, TSK! You FORGOT to mention the "papers" on the ARRL
website describing Peter Martinez' PSK31. [that's not like you]

You are skirting a very grey line on "cryptology." PSK31 is
NOT about "intentional obscuration of the meaning of a
communications," the boilerplate statement in Part 97 on
what can be sent or not sent by radio amateurs.

On the other hand, PSK31 is sufficiently UNLIKE conventional
TTY codings that it cannot be decoded by any TTY machinery
or even Hellschreiber.

Too many have the emotional labeling of "cryptology" in regards
to secrets and spies. In checking out Webster's New World
Dictionary, Prentice-Hall 1989, it defines "cryptography" as
"the art of writing or deciphering messages in code." Tsk, that
would apply to morse codes, wouldn't it? :-)
