Forgive me for making a slight correction to that, Don, but KN is not a 
prosign but is defined as a left-hand bracket in the latest 
recommendations of the ITU. The latest definitions were prepared 
primarily to include the Morse code sequence for @ (prosign AC).

Consequently, K N should really be separated by a space.
