Code groups, sent in morse or voice or any other mode, are
multi-letter/number groups with no apparrent meaning.

It's a conspiracy if you consider all attempts at secrecy conspiritorial.

Remember:
"Sky King, Sky King, Do not Answer, Do Not Answer" etc.
I believe that very type of transmission is mentioned in Francis Gary
Powers' book "overflight".
Which is a heck of an interesting read.
