Thanks Bob, that explains a lot. Yesterday at 1400UTC I did see some PSK31, but too weak to decode. So basically after 11UTC no need to try PSAT2 then. Cheers,

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.

Nobody knows? Here in east Asia some other hams are asking the same. We have good passes late at night (1400 UTC), but no PSK31 or SSTV seen at all. --Hans BX2ABT On 07/04/2019 10:48 PM, Hans BX2ABT via AMSAT-BB wrote: > Hello all.
