Spacelog Apollo 13

Joe, it appears that the best detent possibly to put the stars in the AOT, would be either number 2 or 4. The rendezvous radar antenna is now in the way. You might think of a procedure to get rid of it with minimum power and then we maybe we'll be able to see stars in a couple of minutes here in a lower detent.

Okay, Jim. I think I understood that the rendezvous radar antenna is in the way and you would like a procedure to get it out of the way. Is that right?

That's affirm; at the proper time, and with minimum power.

Aquarius, Houston. Over.

Go ahead.

Okay. Jim, we have a handover coming up on the hour; that's in a minute and a half. On the hour, we would like you to turn the S-BAND TRANSMITTER/RECEIVER switch to OFF, and 5 minutes later turn it back to PRIMARY. Over.

Okay, Houston. Shortly you want us to turn the S-BAND TRANSMITTER/RECEIVER to OFF; 5 minutes later, turn it back to PRIMARY.

That's affirmative, Jim. After the handover apparently they want to make sure that they lockup with you and not the IU.

Roger. And let me know when you want me to turn it off.

Roger. You can turn it off now.

And, Houston, when do you want me to turn that S-BAND TRANSMITTER/RECEIVER off?

Aquarius, Houston. Turn it off now.

Okay, Aquarius; Houston. We have data back and I assume we have COMM. Over.

Houston, This is Aquarius. The COMM is very, very, very noisy. Over.

Aquarius, Houston. Copy that. It's noisy on our end, too; stand by while we think about it.

Houston, Aquarius. I am unable to … now …

Jim, Houston. I think you just called, but I didn't copy you.

Aquarius, Houston. Over.

Go ahead, Houston.

Jim, recommend you push the POWER AMPLIFIER circuit breaker on panel 16 in. Over.

Roger. POWER AMPLIFIER circuit breaker panel 16 going in.

POWER AMPLIFIER circuit breaker is in.

Okay, Jim. How is the COMM now? Over.

A lot of background noise. Let me turn off the SQUELCH.

Okay. You're quite a bit better.

Whenever I enable SQUELCH, I lose you. Over.

Roger. Stand by. You are much better down link.

Look at NOUN 65.

Okay.

Okay, Jim. This is Houston. We recommend that you set the FUNCTION switch from DOWNVOICE BACKUP to VOICE. Over.

Roger. FUNCTION switch going from DOWNVOICE BACKUP to VOICE.

Okay, Jim. How's the COMM now?

FUNCTION switch … There's still a lot of background noise, Joe.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

The noise we're experiencing is similar to what we had sometime before when you switched stations.

Roger, Jim. INCO is checking into what we can do about the noise. It may be a problem with the new site.

Aquarius, Houston. Is the noise any better now? Over.

This is Aquarius. Negative.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

Roger. Will you let us know when you want us to yaw another 90 degrees right?

Go ahead.

We are going to try to improve the COMM and telemetry by temporarily breaking lock and reacquiring. You may hear some noise in your headset.

Okay. Couldn't be any more noise than we're getting now.

Hello, Houston; Aquarius.

Aquarius, Houston. Go ahead.

Okay. Now that there's no noise, you can give …

Jim, I didn't copy that. Your COMM is pretty good, though. How is it with us?

Good. Okay.

Houston, do you want to reconfigure the DOWN VOICE BACKUP again?

Aquarius, Houston. I don't think so at this time. Our voice is good now. How's yours?

Ours is very good.

Okay. Houston, Aquarius. We're deadbanding in the new attitude.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. In order to save on an amp or 2 of power here, we'd like you to go to the DOWN VOICE BACKUP COMM configuration, which is pulling the power and circuit breaker and going to DOWN VOICE BACKUP. If we get into a COMM problem, all you have to do is reverse that configuration, and it should be good again. Over.

Okay, we'll go to DOWN VOICE BACKUP and pull the POWER AMPL circuit breaker, and if we get into trouble, we'll come back again.

Okay, real fine, and we estimate the next yaw maneuver should start at about 68:02. Over.

Okay. Could you give me that in minutes?

I sure can. That's going to be in 29 minutes from now, Jim.

Okay. Thank you.

Okay.

Okay, Houston. We're in DOWN VOICE BACKUP and the POWER AMPLIFIER is pulled.

Jim, Houston. Roger that. You are readable through the noise. How are we? Over.

You are loud and clear.

Very good.

Yes, I guess … at this time … out … configuration …, and we have to get … …

Okay. What else do we have to …

…

Okay.

…

…

…

I guess they're going to take …

…

Well, there's another good one …

… going off?

…

No. … we had battery power for a while, we could …

It's locked.

…

I don't think that was …

… powered up …

… got one.

… … all powered down.
