02 16 38 39
Jim Lovell (CDR): Okay.
02 16 38 54
Jack Swigert (CMP): Joe, has your continued tracking changed our pericynthion altitude any?
02 16 39 01
Joe Kerwin (CAPCOM): Stand by. We'll get the latest on that, Jack.
02 16 39 50
Joe Kerwin (CAPCOM): Aquarius, Houston.
02 16 39 54
Jack Swigert (CMP): Go ahead.
02 16 39 56
Joe Kerwin (CAPCOM): Roger, Jack. We're still looking at 137 miles and Doppler's confirming it. We will have a good update after 67 hours.
02 16 40 08
Jack Swigert (CMP): That's good. I want to say you guys are doing real good work.
02 16 40 13
Joe Kerwin (CAPCOM): So are you guys, Jack.
02 16 47 06
Joe Kerwin (CAPCOM): Aquarius, Houston.
02 16 47 13
Jim Lovell (CDR): Go ahead, Houston.
02 16 47 14
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.
02 16 47 43
Jim Lovell (CDR): Okay. You can read up the steps.
02 16 47 48
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.
02 16 48 39
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.
02 16 48 56
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.
02 16 49 44
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.
02 16 49 54
Joe Kerwin (CAPCOM): That's affirm. We'll just run a little COMM check after you get done and see how we're doing.
02 16 50 03
Jim Lovell (CDR): Okay, fine. And if that all fails, we'll go back to our original configuration.
02 16 50 06
Joe Kerwin (CAPCOM): That's affirm.
02 16 51 01
Jim Lovell (CDR): All amps PRIMARY.
02 16 51 04
Fred Haise (LMP): POWER AMPs in PRIMARY.
02 16 51 06
Jim Lovell (CDR): Okay. Circuit breakers 16, POWER AMP circuit breaker, open; COMM; POWER AMP circuit breaker, open.
02 16 51 18
Fred Haise (LMP): There's only one. Ready?
02 16 51 23
Jim Lovell (CDR): RANGE … switch off.
02 16 51 28
Fred Haise (LMP): It is off. …
02 16 51 35
Fred Haise (LMP): Yes, I think so; yes, that's off.
02 16 51 49
Jim Lovell (CDR): … Okay, Houston; Aquarius. How do you read me?
02 16 51 53
Joe Kerwin (CAPCOM): Aquarius, this is Houston. We read you with a lot … static. How do you read us? Over.
02 16 52 03
Jim Lovell (CDR): We read you with a lot of noise, the noise seems to indicate … read you better.
02 16 52 15
Joe Kerwin (CAPCOM): I didn't copy your last remark, Jim. I heard that you had a lot of noise in the background also.
02 16 52 23
Jim Lovell (CDR): Okay, Houston; Aquarius. How do you read us now?
02 16 52 27
Joe Kerwin (CAPCOM): Just the same, Jim. You're readable but it's very noisy.
02 16 52 45
Jim Lovell (CDR): Okay. We can still read you. Do you want us to remain in this configuration?

Joe Kerwin (CAPCOM): Stay there for the next minute or two anyway, Jim, while we evaluate it.
02 16 53 23
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.
02 16 53 41
Fred Haise (LMP): Yes. Okay. You guessed it.
02 16 53 53
Jim Lovell (CDR): I've come up with nothing here.
02 16 54 47
Fred Haise (LMP): … we can use.
