I've updated my earlier post (#36) with four more recordings. You can find the post here. Kaunan A 1 sounds interesting, as it broke the usual pattern twice - however, Kaunan A 3 didn't.
Excellent - thanks so much for your efforts.
I would like to request that those with UA's take a bit of time to make as many recordings as you can - there's a pattern emerging, and I want to validate my findings. It seems that each time you eject a UA, it doesn't start singing immediately... only when you target it to start 'listening'
