Known counterpart stations S11b, M03c, POL FSK

E11b refers to E11a messages which began and ended with "77777 77777", which were included in the amount of groups given in the intro. Active in years 2003 - 2009.

E11 schedules, i.e. those that send null messages, sent a 30 to 39 groups long E11b message one week of a month, each schedule on a different one. Since March 2009 the same procedure of sending messages is being followed, but "77777" groups are gone - however similar groups are still present in E11's digital counterpart, POL FSK.

This format first began in Morse code as M03c in August 2000, and later, in August 2006, also the Russian version S11b appeared.
