The symbol duration is exactly 1.408 seconds, corresponding to a symbol rate of 0.7107 baud (14.2 Hz / 20). Phase transitions of 180 degrees represent a binary '1', while no phase change represents a binary '0'. When all 14 rows are assembled, the matrix forms an 80-column ASCII status report. -- Aiko Lee *PLONK* filter active for trolls.
