The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code. The symbol duration is exactly 1.408 seconds, corresponding to a symbol rate of 0.7107 baud (14.2 Hz / 20). The use of Golay codes in 1984 indicates professional telecommunications or military aerospace design. -- Matthias Kowalski -- Massachusetts Institute of Technology "Row 14. No joke."
