Each message frame begins with an 8-bit Barker sequence [11100010] for frame synchronization. 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. -- === Renata Müller === Dept of Electrical Engineering, MindSpring Enterprises "Measuring a record you own is listening, not piracy."
