with Spacecraft 6 in the air, I thought went very well. It
posed no problems. Communications Controls &nd Switches
Voice Control Center, Audio modes, Keying and Antenna Selec
tion, were all nominal. We might mention in Sleep Configu
ration--we never used the Sleep switches bees.use we had the
situation where we pretended it was night and went to sleep
every evening and the ground never call ed us. I don't think
they ever violated that for the 14 days. They never called
us during the sleep period.
Lovell So that worked very well.
Borman Beacon Control was no problem. We didn't use the Reentry
C-band Beacon until reentry. The TM controls, tr8Jlsmitter,
and antenna again were no problem. It was operated just a.a
advertised due to all instructions from the ground.
8.6 Electrical
Borman Now we have some interesting things to talk about.
Lovell Well, we monitored the electrical system pretty closely.
Borma.n Yea.h, I guess we did.
Lovell The only thing we can say here is reiterate what we have
probably said before. On lift-off we had delta Plights
come on for fuel cells--both sections. 1 blinked on and
off several times and went off. 2 blinked on and off
several times and stayed on through insertion and stayed on
