Frank Borman (CDR)

Very good; we'll be there.

Frank Borman (CDR)

I don't think those waves are too high. We're going to have to sit in this heap for about 45 minutes.

Ken Mattingly (CAPCOM)

Okay. We'll put in a kit for some small waves.

Frank Borman (CDR)

Tell Jerry Hammack if the waves get high, it's his fault.

Ken Mattingly (CAPCOM)

Okay. Why don't you drive it back over to the PTC attitude and put it back in ATTITUDE HOLD for the roll, and we're going back in and review the DTO requirement. You have about the same results, it looks like, on a cursory analysis all three times. So we're going to take another look and see if there is any reason to do it again. If so, we'll call you. You can go ahead and put it back in ATTITUDE HOLD now.

Frank Borman (CDR)

Houston, Apollo 8. Radio check.

Ken Mattingly (CAPCOM)

Loud and clear, Apollo 8.

Ken Mattingly (CAPCOM)

Roger. It is taking us a little longer to go through and rehash all of the entry checklist than I though, and we are just about to wrap it up now.

Frank Borman (CDR)

No problem. Just watch my gimbal angles for me, and give me a call if they get too close.

Ken Mattingly (CAPCOM)

Roger. We will watch them.

Ken Mattingly (CAPCOM)

We would like to look at a couple more DELTA-V tests on the EMS, and the general consensus is that we don't think there is any particular problem. We'd like to go ahead and take a look at what you get by running four or five more DELTA-V tests. And prior to that, we'd like to run one of these null bias tests; and since we don't have any way of monitoring any of this stuff on the downlink, I'd like to have you tell us each step when you turn the switch and different orders and things like that.

Frank Borman (CDR)

Alright. I'll run a test.

Ken Mattingly (CAPCOM)

Okay. The first thing we want is this null bias, 100 seconds.

Frank Borman (CDR)

You stand by, and I'll do a null bias for 100 seconds. Do you want me to put DELTA-V in AUTOMATIC and let it alone for 100 seconds?

Frank Borman (CDR)

Going to DELTA-V; going to AUTO -

Frank Borman (CDR)

Went to one-tenth and back to zero.

Ken Mattingly (CAPCOM)

Understand; plus one-tenth and back to zero.

Frank Borman (CDR)

One-tenth, now it's a minus one-tenth and back to zero; no, it's not zero yet; wait a minute.

Frank Borman (CDR)

Now it's up some, minus 4; 0.4, that is.

Frank Borman (CDR)

Minus 0.7, and there is 100 seconds; minus 0.7 at 100 seconds.

Ken Mattingly (CAPCOM)

Okay. If we go back to mode, switch to stand by and FUNCTION switch OFF.

Ken Mattingly (CAPCOM)

Okay. Now we'd like to do a couple of DELTA-V self-tests.

Frank Borman (CDR)

Say you're going AUTOMATIC?

Frank Borman (CDR)

Going to a DELTA-V test now. Counting down.

Ken Mattingly (CAPCOM)

Apollo 8, this is Houston.
