Well, with AO-13 gone, we needed something to replace "Mode B starts at
Phase x, with Mode BS at x+y, and what does phase have to do with time
anyway...?" <grin>

Amateur TX-on (TEPR 4) starts 24 minutes after eclipse end; Amateur TX-off
(TEPR 5) is at 39 minutes after eclipse end; total time-on is 15 minutes.
The TEPR "units" of time are 30-second increments, not minutes.
