[amsat-bb] PSAT2 SSTV/telemetry intervals?

[Robert Bruninga]

SSTV operation is entirely bus voltage driven.  If there is plenty of
voltage, then SSTV will be frequent.  If it is dark and battery voltage is
blow somehing like 6.8? volts then it will not transmitt SSTV.  SSTV takes
a lot of power.
You can see the bus voltage as the firs channel in the T$SSS,VVV,III,
TTT,TTT,... telemetry.  Volts is in hundredths.
