Ken Mattingly (CAPCOM)

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

Ken Mattingly (CAPCOM)

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.

Bill Anders (LMP)

Roger. On upvoice backup.

Bill Anders (LMP)

Roger, Houston. Read you loud and clear.

Ken Mattingly (CAPCOM)

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

Ken Mattingly (CAPCOM)

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.

Ken Mattingly (CAPCOM)

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.

Bill Anders (LMP)

How's everything looking down there?

Ken Mattingly (CAPCOM)

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

Ken Mattingly (CAPCOM)

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

Ken Mattingly (CAPCOM)

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

Bill Anders (LMP)

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

Ken Mattingly (CAPCOM)

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

Bill Anders (LMP)

Roger. Stand by. What time is that for?

Ken Mattingly (CAPCOM)

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

Ken Mattingly (CAPCOM)

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.

Ken Mattingly (CAPCOM)

Apollo 8, we would like to dump your tape again, if you are not using it. And the reason we want to do this is we have some—we didn't completely get dumped before the burn. We would like to get that and get the rest of the burn data. There is no hurry on it. We can do it whenever it is convenient for you.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Do you call?

Bill Anders (LMP)

Negative, negative. Negative, Houston.

Ken Mattingly (CAPCOM)

Okay. Thank you. Say, we're curious about what you did with your Mae West?

Bill Anders (LMP)

We thought we might bleed the CO2 out into the vacuum connector here in our next water dump. We forgot it the last time. Did you copy?

Ken Mattingly (CAPCOM)

Roger, Doesn't seem like there is any problem with going ahead and dumping it in the cockpit if you like.

Ken Mattingly (CAPCOM)

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.

Bill Anders (LMP)

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

Ken Mattingly (CAPCOM)

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