[Elecraft] K3 CW to Data and "ES" for ampersand?

[Kevin Rock]

International Morse code does not use certain half spaces like the  
American Morse code does.  However there are still half spaces in well  
formed code in certain prowords such as DE and ES.  If you send them  
without the half space they don't mean the same thing.  Therefore you can  
sense meaning from the spacing.  Since that is the way it has been used  
and still is being used why should we change the protocol?
    Kevin.
