S11b refers to S11a messages sent in years 2006-2009, which began and ended with "77777 77777". Such messages were sent on a randomly chosen week once a month. These groups were dropped in March 2009, but the once a month message procedure was retained.
This format first began in Morse code as M03c in August 2000, joined by the English counterpart E11b in August 2003.
