Here's the video of this evening's main testing.

(Sorry about the poor quality right now, YT is taking an age about the processing)
All tests conducted in the shadow of Sleipnir A 1 with Cmdr nilreb.
0:00 - 1:22 / Only UA. 5 purrs.
1:35 - 2:43 / UA + 8x SAP8. *3 purrs*
3:32 - 4:00 / UA + 6x SAP8. *3 purrs*
4:25 - 5:03 / UA + 5x SAP8. 5 purrs.
8:40 - 10:20 / UA + 6x SAP8. 5 purrs.
12:40 - 14:25 / UA + 7 SAP8. 5 purrs.
16:24 - 17:54 / UA + 8x SAP8. 5 purrs.
It seems that it takes 8x SAP8 near the UA to change the sound from 5 purrs between honks to 3 purrs.
Also, the UA must in within the "cloud" of SAP8s. If the distribution is too loose, the UA emits 5 purrs like normal.
Distribution of the SAP8 around the UA when it made 3 purrs.
The video stopped because I think it hit some file limit. I did some more listening with 8x SAP8 and tried nudging 2 of them closer, which didn't seem to make a difference.
I agree that 12x SAP8 in close proximity to a UA is the way to go with further testing. We need to work out exactly how far cargo drifts from the cargo hatch and get 2-3 people to try and drop SAP8s into a small area with a UA in the middle.
What I think this means though is that 8x SAP8 "activates" something about the UA.
One of the tests I'll be performing soon is travelling to Polaris and see if it makes a difference to entering the system (I'm not expecting to be able to). Confirm or deny, I'll find out.
I'm currently parked up in Leonard Nimoy Station btw.
