From the Mission transcripts, this interaction, as the crew is performing their checklist operations, takes place right before the radar antenna moves:
145:30:06 Bean: Okay, you need to pull both rendezvous circuit breakers.
....
145:30:16 Conrad: Okay. Got those out. Rendezvous radar breakers are pulled from the Verb 44.
Thank you for this post.
One note is that these breakers are for the Rendezvous breakers, not S-Band. So should be fully unrelated. I believe this marks the point where they simply stop using the Rendezvous Breaker, and switch to eyeballing it, right?
Right after the antenna moves there is this statement made:
145:31:56 Bean: My antenna's okay.
This to me looks like part of the "damage control", to say something about the antenna.
I was using the TV transmission, which had NAT SOT audio. Additionally the 16mm DAC footage was properly synched to this TV feed.
Can you please clarify what you mean here, maybe provide some links/time-stamps if applicable?
This to me looks like the in-built auto-correction capability of the steerable antenna which is during the time where Conrad engages -both-circuit breakers. it also corresponds to Bean stating "My antenna's OK" once the procedure has been completed.
The uncontrolled pendulum like motion looks like "auto-correction"? The orientation of the S-Band for the first 30 degrees of the Pitch rotation is correct (confirmed it)... it's pointing to where the earth should be. As it rotates, we see what looks to me as "strain" on the armature as it starts to come away from the LM body (which it's not designed to do)... What it snaps, it behaves unlike a server motor is involved at all -- hitting the hinge extremes and bouncing off of them, then it settles into a pendulum behavior, decreasing each time... not of this looks like servo-motor operation which is slower and rigid. Not loose.
During this flailing, it goes from being "aimed at earth" to being aimed Not-at-earth--- and then freezes up and doesn't move again.
So if this was "auto-correction to find earth" - it would make no sense that it didn't then CONTINUE to track earth steadily for the remaining 55 degrees of the pitch maneuver.

For me the most damning aspects of this incident are:
1. The misalignment of static with "changing over to omni aft" antenna. What exactly was supposed to be the action or incident that caused this static? (the flinging of the Dish, or the switchover to Omni Aft?)
2. The strain on the armature moving in a direction without a hinge for it.
3. The flip flopping about - doesn't look like anything this servo-motor controlled device should ever do.
4. The settling out in pendulum fashion (continuously decreasing amplitudes - no longer bouncing off of the hinge extremes, but being pulled back by "something else").
