Ronald Evans (CAPCOM)

Columbia, Houston. You're about one by, I could just barely make you out. I can't understand.

Michael Collins (CMP)

Houston, Columbia. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Buzz Aldrin (LMP)

Houston, this is Eagle. Over.

Ronald Evans (CAPCOM)

Hey, Eagle. Houston loud and clear. Columbia was very weak. We were unable to read him.

Buzz Aldrin (LMP)

Roger. We saw you come up over the horizon and it looks like you had a laser operating. Could you confirm that?

Ronald Evans (CAPCOM)

Eagle, Houston. Stand by. We'll check it. And, Eagle, Houston. Can you give us a burn report?

Buzz Aldrin (LMP)

Okay. The CSI burn was on scheduled time of 125 19 3470, 51.5 feet per second was our solution. After chasing residuals a little bit, we ended up with a minus 0.2, plus 0.7, and minus 0.1. And in the AGS, at that time, we had plus 0.4, plus 0.9, and plus 0.3.

Ronald Evans (CAPCOM)

Eagle—Eagle, Houston. We copy. Any plane change? Over.

Buzz Aldrin (LMP)

No. There was no plane change on CSI, and CSM had a 2.3 foot per second burn. We had a 2.9, and we elected to postpone that. Over.

Ronald Evans (CAPCOM)

Roger. We copy, Eagle. Thank you.

Michael Collins (CMP)

Houston, how do you read Columbia now?

Michael Collins (CMP)

Eagle, how about asking them for some high gain angles for me, will you, please?

Buzz Aldrin (LMP)

Roger, Houston, do you have some high gain angles for Columbia? Over.

Ronald Evans (CAPCOM)

Roger, Eagle. And, Columbia, stand by. We'll have them for you shortly.

Ronald Evans (CAPCOM)

Eagle, Houston. Could you verify you switched lithium hydroxide canisters? Over.

Buzz Aldrin (LMP)

That's affirmative. We started getting an erratic indication on primary, so we switched to secondary, and it was again erratic and I thought it might have been a sensor. But it's settled down now, and we're on the secondary. Over.

Ronald Evans (CAPCOM)

Roger. We copy. Mighty fine.

Ronald Evans (CAPCOM)

Columbia and Eagle. Request OMNI Delta for Columbia.

Michael Collins (CMP)

Roger, Houston. I've been in Delta the whole time but it doesn't …

Neil Armstrong (CDR)

Houston. Columbia's been on Delta, but he hasn't had much luck with you.

Ronald Evans (CAPCOM)

Eagle, Houston. Roger. We copy.

Michael Collins (CMP)

Eagle, are you ready to copy your Y dot?

Ronald Evans (CAPCOM)

Eagle, Houston. At your convenience, we'd like to go ahead and try your lithium hydroxides on the primary and let us take a look at it down here.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.

Neil Armstrong (CDR)

Houston, Eagle. Columbia's been reading you loud and clear on his OMNI's, but he hasn't had any luck in transmitting to you.

Ronald Evans (CAPCOM)

Roger, Eagle. Mighty fine. We don't hear Columbia though.

Buzz Aldrin (LMP)

We're burning ours, Mike. Minus 1.8.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.

Ronald Evans (CAPCOM)

Columbia, Houston. You can go ahead and go to REACQ in the high gain. We should get you then.

Buzz Aldrin (LMP)

Do you have some angles for him, Houston?

Ronald Evans (CAPCOM)

Roger. Pitch minus 30, yaw 180, for Columbia.

Buzz Aldrin (LMP)

Okay. And what was your CSICDH solution, Mike?

Buzz Aldrin (LMP)

Roger. Copy. Thank you.

Neil Armstrong (CDR)

And, Houston, Eagle. Got an ECS light—a CO2 light. Partial pressure's reading about one half millimeter.

Ronald Evans (CAPCOM)

Eagle and Columbia, Houston. Roger. We copy.

Michael Collins (CMP)

Houston, how do you read Columbia?

Ronald Evans (CAPCOM)

Eagle, Houston. We're sure that's a sensor problem. You can leave it on PRIMARY.
