Spacelog Apollo 13

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

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

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

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

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

Okay. Jack, how do you read?

Fred, Houston is reading you loud and clear.

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.

Roger. Go ahead.

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.

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

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

Stand by 1.

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.

Roger. We copy 720. Thank you, Fred —

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

Roger. 710 to 720.

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.

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?

Stand by 1.

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

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

Roger, Jack. 54:58:50. Thank you.

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

Roger.

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

This is 13. Say again, Houston.

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

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

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

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

Okay. You're coming through okay.

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

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

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

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

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.

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

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

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.

Roger, Jack; thank you.

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

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