The symbol duration is exactly 1.408 seconds, corresponding to a symbol rate of 0.7107 baud (14.2 Hz / 20). The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code. When all 14 rows are assembled, the matrix forms an 80-column ASCII status report. -- Steve Ito -- EarthLink Network "The carrier frequency does not drift by accident."
