Michael Collins (CMP)

Houston, Columbia is unable to read Eagle on either antenna or on VHF duplex Bravo. You got any suggestions?
-
Michael Collins (CMP)
-
Houston, Columbia. Also my VHF ranging is not working now, and I'd like to know whether you'd like me to continue making sextant marks or do nothing. I'm supposed to be doing VHF marks only, and it's for the next 6 or 7 minutes.
-
Ronald Evans (CAPCOM)
-
Columbia, Houston. Roger. We copy. And, Eagle, looks like the best antenna would be forward for the LM. And, break. Eagle, we missed your loading of the TPI TIG and P32. Could you confirm you've done that?
-
Ronald Evans (CAPCOM)
-
Columbia, Houston. Recommend you take sextant marks and do not reinitialize. Over.
-
Michael Collins (CMP)
-
Roger, Houston. Columbia's got the VHF ranging back now. I'll stick with the nominal. Thank you.
-
Ronald Evans (CAPCOM)
-
Roger. Mike, you can go ahead and get as many VHF and sextant marks as you can here in this period of time.
-
Michael Collins (CMP)
-
Roger. I've just got time for maybe two sextant marks, then get on with the final count.
-
Ronald Evans (CAPCOM)
-
Eagle and Columbia, about 1 minute till LOS there on Columbia. It looks like we have about 51.5 for CSI, and we tend to confirm your Y dot. And, break. For Eagle, verify VHF Bravo transmitter is off.
-
Ronald Evans (CAPCOM)
-
Eagle, Houston. Recommend aft OMNI and are you GO for CSI, so we can let Columbia know. Over.
-
Ronald Evans (CAPCOM)
-
Eagle, Houston. We'll see you coming around the other side. Your AOS time—is 1 minute ahead of the flight plan.
-
Ronald Evans (CAPCOM)
-
Columbia, Houston. Heard you talked to Eagle? I assume you have COMM with Eagle now?
-
Michael Collins (CMP)
-
Roger. Houston, Columbia. CSI nominal; no plane change. Everything's going beautifully, and the LM seems to be …your laser…
-
Ronald Evans (CAPCOM)
-
Columbia, Houston. You're about one by, I could just barely make you out. I can't understand.
-
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.
-
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.
-
Michael Collins (CMP)
-
Eagle, how about asking them for some high gain angles for me, will you, please?
-
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.
-
Neil Armstrong (CDR)
-
Go ahead.

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.
-
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)
-
Columbia, Houston. You can go ahead and go to REACQ in the high gain. We should get you then.
-
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, Houston. We're sure that's a sensor problem. You can leave it on PRIMARY.
