Mathematical proof of the modulation scheme used on the 14.2 Hz carrier across all regional pressings.

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).

When all 14 rows are assembled, the matrix forms an 80-column ASCII status report.

A symbol rate of 0.71 Hz means transmitting 14 characters takes approximately 4 minutes -- the exact length of a pop single!

Every song on SYNTHESIS was engineered to be exactly long enough to transmit one complete telemetry frame.
