Spacelog Apollo 8

Go ahead.

We're starting in now on our fourth test. Like for you to put your TELEMETRY INPUT switch to PCM HIGH.

It's in HIGH.

Okay. And now we're going to switch uplink to the upvoice backup for about 2 minutes, and it may take a couple of seconds when you hear the upvoice lost. So you can place your up-telemetry switch to upvoice backup, and in the event that all of this doesn't work out too well, I'm reading 12:47 on my clock now, and let's meet back in our present configuration no later than 12:50.

Roger. On upvoice backup.

Okay. Thank you.

Apollo 8, Houston.

Roger, Houston. Read you loud and clear.

That's pretty good. That's upvoice backup, and will you confirm that you're in NARROW BEAM on high gain?

Roger. NARROW BEAM.

Okay. Thank you. We're going to continue tracking and watching high-gain antenna for a couple of minutes. Then I'll give you a call when we're ready to go back.

Roger.

Apollo 8, Houston. We have completed this test. We'll be switching back to full uplink. When you hear the noise associated with the loss of modulation, you can go back from the up-telemetry switch to DATA.

Thank you.

All the way.

Okay. Loud and clear.

How's everything looking down there?

Real fine. We've just got one to go here if you'll put your telemetry input PCM switch to LOW.

Roger. Go in LOW.

Okay. We'll be in that configuration for about 2 minutes, and then we'll be completed with the COMM test.

Roger.

I have some service module RCS quantities if you would like to take them sometime and check them against your onboard calculations.

Stand by.

Roger. Ready to copy. Could you give quad A, B, C, and D in that order?

Okay. Will do. And I'll give you weights in pounds and percentages. Quad A 231 for 76 percent.

Roger. Stand by. What time is that for?

Oh, 12 plus 15.

Okay. Got it.

Okay. Quad Bravo 251, 82 percent. Quad Charlie 240, 79 percent.

Slow down.

Quad Delta 245, 81 percent. P and C advises that these numbers are still good even though it is a 12:15 time. And we are completed with the COMM test. You can take your high-gain antenna and go back to MEDIUM.

It is CO₂, isn't it?

That's affirm.

Apollo 8, Houston. We asked it again, and it looks like no problems at all with going ahead and bleeding it down in the cockpit. And then if you need it again on entry or after entry, well, we can blow it up with oral tube.

Apollo 8, Houston.

Apollo 8, Houston.

Apollo 8, Houston.

Apollo 8, Houston.

Houston, Apollo 8. Read you loud and clear. How us?

Okay. Loud and clear. Didn't get you there for a while.
