     Well, write about the ROs on the Suez, it sounds like an 
interesting story.
     I read somewhere that the method of using TTT and XXX was to 
send them just before a silent period to alert operators to 
listen for the complete message just following the SP. At least 
on 500Khz that would insure a large audience.
