Hi all! What power management scheme is used for so-50 and ao-51 when the birds are eclipsed? thanks, Norm n3ykf _______________________________________________ Sent via AMSAT-BB@amsat.org.

Right now, AO-51 shuts off the transmitters when the battery voltage dips below a setpoint, or the panels drop below 14v. It turns back on when the battery voltage reaches a separate setpoint.
SO-50 has no power management that I'm aware of, other than the PL tones used to activate it. It should be functional in eclipse.
