Roger, Jack. We're still looking at 137 miles and Doppler's confirming it. We will have a good update after 67 hours.
- Joe Kerwin (CAPCOM)
-
Okay, Jim. We've come up with a COMM recommendation which we hope will save some power by powering down the power amplifier, if it works. And I'd like to read up the steps to you and have you think about them for a minute, and we recommend trying it before the first yaw maneuver. Over.
- Joe Kerwin (CAPCOM)
-
Okay. Step 1, BIOMED off; step 2, go to LOW BIT RATE; step 3, go to DOWNVOICE BACKUP; step 4, POWER AMP to PRIME; step 5, panel 16, POWER AMP CIRCUIT BREAKER open; step 6, RANGE FUNCTION switch, off. Read those back to me, and then I'll have a remark.
- Jim Lovell (CDR)
-
Okay. BIOMED, off; LOW BIT RATE; DOWNVOICE BACKUP; POWER AMP to PRIME; circuit breakers, panel 16, POWER AMP CIRCUIT BREAKER, open. RANGE FUNCTION switch, off.
- Joe Kerwin (CAPCOM)
-
Okay. And the note says that you should be able to hear us. If we can't hear you in a couple of minutes, you should close the POWER AMP circuit breaker on panel 16, and we expect to save an amp or more on this. It should work in the present attitude. When we go to the new yaw attitude, we're thinking about powering up the steerable, leaving the POWER AMP off and, if we can get good COMM in that mode, we'll still save some power. So if you concur, why don't you go ahead.
- Jim Lovell (CDR)
-
Okay. In this mode, you should hear us—or we should hear you, but if you can't hear us, then we ought to close POWER AMP circuit breaker again. Is that right.
- Joe Kerwin (CAPCOM)
-
That's affirm. We'll just run a little COMM check after you get done and see how we're doing.
- Jim Lovell (CDR)
-
Okay. Circuit breakers 16, POWER AMP circuit breaker, open; COMM; POWER AMP circuit breaker, open.
- Joe Kerwin (CAPCOM)

Aquarius, this is Houston. We read you with a lot … static. How do you read us? Over.
- Joe Kerwin (CAPCOM)
-
I didn't copy your last remark, Jim. I heard that you had a lot of noise in the background also.
- Jim Lovell (CDR)
-
Okay. I'll tell you what we need, Jack. Try to get this squared away again. We—See if you can't report the right procedures here. … the procedures, the whole works, before we get all balled up here.
- Jim Lovell (CDR)
-
… Well, we should have some around here somewhere.

Why don't you put that right up there, just like that. Is that all you've got on it? There you go.
- Joe Kerwin (CAPCOM)
-
Okay. Speak slow because there's a lot of noise in the background. Have you completed your first 90-degree yaw maneuver? And, if you haven't, we recommend it. Over.
- Jim Lovell (CDR)
-
Okay. We have not. We have not completed it. We will start. We want you to monitor the maneuver. Over.
- Joe Kerwin (CAPCOM)
-
Okay, Jim. And I want to pass you up a short procedure for activating the S-band steerable antenna, which we'd like you to do after you complete the 90-degree yaw. Are you ready to copy? Over.
- Joe Kerwin (CAPCOM)
-
Okay. First, on panel 11, close the S-BAND ANTENNA circuit breaker. Then go to Activation, page 28, steerable antenna activation —
- Joe Kerwin (CAPCOM)
-
— and complete steps 2, 3, and 4 of Activation 28. You'll have to do a VERB 64 to get the pitch and yaw angles, and the last step is on panel 16, S-BAND ANTENNA HEATER circuit breaker to CLOSE. Over.
- Jim Lovell (CDR)
-
Joe, we didn't get all of that. We just have, “Complete steps 2, 3, and 4 of activation” and then 68 or 28.
- Jim Lovell (CDR)
-
Disregard it. Okay. Do you want me to start my yaw maneuver now? And I'll be yawing to my right. One-way maneuver.
- Joe Kerwin (CAPCOM)
-
Okay. You are GO to commence the yaw maneuver. If we don't have COMM after you complete the yaw maneuver, bring the power amplifier back on. Over.
- Jim Lovell (CDR)
-
And, Houston, could you give us an approximate time to turn off the ascent O2 in case we're losing point with you?
- Jim Lovell (CDR)
-
Roger, Houston. We'd like a time to go back to descent O2 in case we lose communications with you.
- Jim Lovell (CDR)
-
Probably not, if everything holds together because we already made one burn.

Okay. Real good. You are clear. We still have a lot of noise, but if you talk slow I think we can manage.
- Joe Kerwin (CAPCOM)
-
Roger, Jim. We're trying to improve our COMM down here. We'd like to try going function switch from DOWN VOICE BACKUP to VOICE. Over.
- Joe Kerwin (CAPCOM)
-
Aquarius, Houston. We're not reading you at all. Request you go back to DOWN VOICE BACKUP. Over.
- Joe Kerwin (CAPCOM)
-
Okay, Jim, since we're in LOW BIT RATE now, we cannot monitor the DSKY for program alarms, et cetera, and we recommend that, in order for you to do so on board, you push in the following circuit breakers: On panel 11 and panel 16 the ANUNCIATOR/DOCK/COMPONENT circuit breakers. That will allow you to monitor your DSKY warning lights. Over.
- Joe Kerwin (CAPCOM)
-
Okay, Jim. The circuit breakers are the ANUNCIATOR/DOCK/COMPONENT circuit breakers on panel 11, third row, far right, under LIGHTING; and on panel 16, also under LIGHTING, second row, third from the left. Over.
