CapCom

Apollo 13, Houston.

CapCom

Okay, to answer your question, Jim, that increase in pressure is normal, because it was just tracking an increase in cabin pressure.

Jim Lovell (CDR)

We're not thinking today.

CapCom

And, 13, from Houston, it's okay with us if you want to move the O2 fuel cell purge and the water dump up to this time. Over.

Jim Lovell (CDR)

Okay. We'll work it in shortly. Thank you.

CapCom

Apollo 13, Houston.

CapCom

Jim, recommend you stay in the PTC until we stop it for the TV at 55 hours, in case you were thinking of —

CapCom

Roger. Recommend you continue PTC until 55 hours. Over.

Jim Lovell (CDR)

You were calling, Houston?

CapCom

That's affirmed, Jim. How do you read now?

Jim Lovell (CDR)

Okay. We read you loud and clear.

CapCom

Okay. The only comment that we just made was that, in case you were thinking of stopping PTC, there's no need to stop it until 55 GET when TV starts.

Jim Lovell (CDR)

Right. We'll stop it when we're setting up our TV.

Jack Swigert (CMP)

Okay, Houston, the waste water dump and O2 fuel cell purge are complete.

Fred Haise (LMP)

Okay, Houston, the LM/CM DELTA-P is constant. We're going to go ahead with hatch removal.

John Young (CAPCOM)

No, this is Jack's replacement.

John Young (CAPCOM)

This is Houston. Go ahead, 13.

Jack Swigert (CMP)

Okay, Houston; Apollo 13.

Jack Swigert (CMP)

Okay. The LMP has entered the LM.

John Young (CAPCOM)

It sure is. How're you doing?

John Young (CAPCOM)

Yes, you're doing great, man.

Jack Swigert (CMP)

Thank you. I had a good CDR.

John Young (CAPCOM)

You're doing it on your own now.

Fred Haise (LMP)

Yes, it feels like I'm back at home, again, John, down in here.

Jack Swigert (CMP)

I hope you did a good job, John.

Jack Swigert (CMP)

Okay, Houston, we want to take the FM and bring up TV here for our own use. Then we'll go to TRANSMIT 1—at 55 hours.

Jack Swigert (CMP)

Okay, Houston, we've transferred to LM power; the time was 54 hours 46 minutes 15 seconds.

Jack Lousma (CAPCOM)

Roger, Jack. Transfer to LM power. Thank you.

Fred Haise (LMP)

And the docking-tunnel index, Jack, was minus 2 degrees.

Jack Lousma (CAPCOM)

Say again, Fred, you're coming in with a lot of background noise.

Fred Haise (LMP)

Okay. The docking-tunnel index mark was minus 2 degrees.

Fred Haise (LMP)

Okay. Jack, how do you read?

Jack Lousma (CAPCOM)

Fred, Houston is reading you loud and clear.

Fred Haise (LMP)

Okay. I've got up through step 7 now, and I'm not getting much of a light in the helium indicator here. Why don't I review for you how we've proceeded, and you look at the procedure you gave me, and see if we've missed anything.

Fred Haise (LMP)

Okay. We transferred to LM power and that looked okay. I'm staring at a CAUTION AND WARNING POWER light, and all the red flags; and we got both X LUNAR BUS TIE breakers IN. The UTILITY LIGHTING breaker is IN; then AC BUS B HELIUM PQS DISPLAY; the AC BUS B NUMERIC LIGHTING, and AC BUS B INVERTER 1 is—BUS TIE is CLOSED. Then I closed the INVERTER 1 breaker, and I've selected, on panel 16, and the SIGNAL CONSENSOR [sic] breaker is in; I've selected INVERTER 1 and put the HELIUM MONITOR switch to SUPERCRIT and I have no lights.

Jack Lousma (CAPCOM)

Okay, Fred, let us take a look at it.

Fred Haise (LMP)

I was wondering, do we need an A—do we need, possibly, in the—one of the ANUN/DOCK/COMPONENT breakers in?

Fred Haise (LMP)

Okay, Jack. Hold the phone. I forgot the rheostat was cranked all the way down on the ANUN/NUM and it's showing 720, which looks like a pretty good—pretty good number.

Jack Lousma (CAPCOM)

Roger. We copy 720. Thank you, Fred —

Fred Haise (LMP)

Flashed to 7—Okay, and it just flickered down to 710. It's kind of flickering between 710 and 720.

Jack Lousma (CAPCOM)

Okay, Fred. Those are good numbers, and we're not going to have to crank up the TM. That's the number we were looking for.

Fred Haise (LMP)

Very good. Okay. Do you want me to back out of this in reverse at least as far as getting this part of it powered down?

Jack Lousma (CAPCOM)

Fred, this is Houston. Go ahead and back out of this little test and proceed.

Jack Swigert (CMP)

Okay. We're back on CSM power. The time was 54 hours 58 minutes 50 seconds.

Jack Swigert (CMP)

Okay, Houston, we'll try to pick you up on the high gain.

Jack Lousma (CAPCOM)

And, 13, we're ready on the TV when you are.

Jim Lovell (CDR)

This is 13. Say again, Houston.

Jack Lousma (CAPCOM)

13, we're ready on the TV when you are. Any time.

Jim Lovell (CDR)

Okay, sounds good. With you in a minute, we're just cranking up high gain now.

Jim Lovell (CDR)

Okay, Houston. How do you read us in the high gain?

Jack Lousma (CAPCOM)

We're hearing you 5 square, Jim, how me?

Jim Lovell (CDR)

Okay. You're coming through okay.

Jack Lousma (CAPCOM)

As you were on that, Jim. We don't have you on high gain yet. We're still looking at you.

Jack Lousma (CAPCOM)

13, Houston. In this attitude, we'd suggest pitch 5, yaw 237 on the high gain. Over.

Jim Lovell (CDR)

Pitch 5, yaw 237. Roger.

Jack Swigert (CMP)

Okay, Jack. Can you—can you read the high gain now?

Jack Lousma (CAPCOM)

Affirmative, Jack. We've got you on a high gain and it appears to us that we're in wide beam—wide beam width.

Jack Swigert (CMP)

Yes. We can't get it to come down to narrow. We tried to switch to AUTO track or REACQ, and it—yaw drives around from 270 to 0. And pitch goes from about 6 degrees around to 90. I'm trying—we're fitting it manual now at the angles that you gave us, and I'll try and get you in medium and narrow beam widths picking it up manually here.

Jack Lousma (CAPCOM)

Roger, Jack. Meanwhile, we'll look at the situation you describe there.

Jack Swigert (CMP)

Okay. And it does it on both sets of servo electronic power.

Jack Swigert (CMP)

Jack, what it looks like is that, when we hit 239 degrees at this attitude, it hit some sort of scan limit or something and drops off.

Jack Swigert (CMP)

Okay, I'm trying you in wide or medium beam width now.

Jack Swigert (CMP)

Can you pick up the TV in this condition here at all?

Jack Lousma (CAPCOM)

Negative, Jack. We'll have to have the narrow beam width.

Jack Swigert (CMP)

Okay. Can you give us, maybe, a slight maneuver?

Jack Lousma (CAPCOM)

Jack, we'd like you to check two high gain circuit breakers down in panel 25. Check your high gain group 2 and your high gain in the flight bus. Over.

Jack Swigert (CMP)

Okay. Okay, Jack, they're both IN.

Jack Lousma (CAPCOM)

13, we've got an attitude suggestion for you. We suggest that you go to roll 285 and try pitch 90 and yaw 0. Over.

Jim Lovell (CDR)

Okay, Houston; Apollo 13. I think we've got high gain locked up now. Do you confirm?

Jack Lousma (CAPCOM)

We confirm that, Jim, we've got you locked up on the high gain and narrow beam.
