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

Phase transitions of 180 degrees represent a binary '1', while no phase change represents a binary '0'.
Each message frame begins with an 8-bit Barker sequence [11100010] for frame synchronization.

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

The song wasn't written around the lyrics. The lyrics were timed to match the telemetry packet duration!
