Nothing much to see. I am sure this is already known but since I can't see it mentioned on the 1st page or in the spreadsheet...
Seems to be no doppler effect on the broadcast, travelling towards the ship does not affect the image.
And no broadcast can be heard external to the ship.

So UP disables parts of the ship, ship's audio systems interpret what's being broadcast. There is actually nothing audible?
Carrying on from this...
I took a recording external to the ship, another internal, spectrograghed with a view to diffing them.
I am no expert at this but it looked pretty fruitless in that I couldn't get it to show anything new.
