Ken Mattingly (CAPCOM)

Apollo 8. We can't handle the OMNI switching for about thirty more minutes, till we get back to an 85-foot dish, so you will have to watch the antenna store for a few more minutes.

Bill Anders (LMP)

Okay. I don't see any loose sensor—the upper, upper …

Bill Anders (LMP)

Are you trying to call, Houston?

Ken Mattingly (CAPCOM)

No, I didn't. It sounded like you were getting an echo, and I checked, and I hadn't held the key down at the time either.

Bill Anders (LMP)

Okay. I don't see any loose sensors, but the upper sternal is beginning to irritate a little bit, but not badly; and possibly there is something going on there.

Ken Mattingly (CAPCOM)

Okay. And did you copy about the antenna?

Bill Anders (LMP)

They really disappoint me, but I'll keep that in mind.

Apollo 8, Houston. Radio check.

Apollo 8, Houston. Radio check.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Radio check.

Ken Mattingly (CAPCOM)

Apollo 8, Houston in the blind now. We're not receiving down-voice. We have data, and it appears it's probably a ground problem.

Bill Anders (LMP)

Roger, Houston. Read you loud and clear.

Ken Mattingly (CAPCOM)

Okay. I got you that time. I take it you were able to copy us with the music? Is that affirm?

Bill Anders (LMP)

I was able to copy you all the time, Ken, but I could only hear the music when you were trying to transmit. And I wondered if you noticed cycling on my suit power switch when you—when you called me. I am hearing an echo now.

Ken Mattingly (CAPCOM)

Roger. I copy your echo. And what switch were you cycling?

Bill Anders (LMP)

I was cycling the suit power which turns off the BIOMED periodically. I figured that would wake the doctors up.

Ken Mattingly (CAPCOM)

It appears that we have more than one communications problem.

Bill Anders (LMP)

You are cutting out, Houston.

Ken Mattingly (CAPCOM)

Oh, that was an inadvertent cut-in.

Bill Anders (LMP)

You need the high gain, Houston, or will the OMNI's be okay?

Ken Mattingly (CAPCOM)

8, Houston. That's negative. The OMNI is okay.

Bill Anders (LMP)

Roger. Be advised that about 50—I am hearing these echos quite a bit of the time, and if you are trying to play music, I am not hearing it.

Milt Windler (FLIGHT)

Roger. We understand, and we are not trying to play music right now.

Bill Anders (LMP)

Okay. Who is this, COMM TECH?

Milt Windler (FLIGHT)

Ken is only human. This is his substitute; this is Flight Director.

Bill Anders (LMP)

Oh, I didn't recognize your voice there.

Milt Windler (FLIGHT)

I don't get to talk often.

Bill Anders (LMP)

Who is substituting for you now, Flight?

Milt Windler (FLIGHT)

DFD.

Bill Anders (LMP)

Okay. Things are looking pretty good from here. How about down there?

Milt Windler (FLIGHT)

It couldn't be better.

Bill Anders (LMP)

You guys are doing a great job. I really appreciate it.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Going to be handling over sites at 25. I will make a voice check with you when we come up on the new site, and the ground says thank you for your kind words.

Bill Anders (LMP)

Okay. We will be standing by.

Ken Mattingly (CAPCOM)

Apollo 8, Houston through Honeysuckle.

Bill Anders (LMP)

Roger, Houston. Loud and clear.

Ken Mattingly (CAPCOM)

Okay, Bill, and our BIOMED data still looks a little bit squirrelly. How about checking the blue signal conditioner on your BIOMED harness. You have one connector, should be the center package, has a blue connector on it. You kind of check that, and I don't know if you have changed the BIOMED harness leads recently; if you have, this might have caused our problem.

Bill Anders (LMP)

Roger. I was just cracking open some acorns here for breakfast. Let me put them down, and I will check my BIOMED leads.

Bill Anders (LMP)

Everything seems shipshape.
