Yeah the clicking starts up just prior to the location block, then the morse comes in, the clicking continues throughout, the morse ends then the clicks quickly slow down.
It's this clicking you're referring to right? If that's what you mean it's always been there, sometimes it's more obvious than others but it's not new.
It's essentially like an "envelope" marking the location morse.
Yes, that one.
But what I mean is: if there are sounds that "appear" or "disappear" in particular conditions, there could be other sounds that we have not heard, never. Still.
@Ratking15:
It is almost the same sound, in your video and in mrTree. But what I'm saying is that there could be other sounds that are there, and we did not hear them until now.
Trying to listen to the UA with an Orca, that is the most hated ship in ED, almost nobody owns it, while the UA is chanting like a Whale, then like a Dolphin/Orca, all the time... still let me think.
But I'm a jolly good funny guy, and that could be a jolly good joke from ED.
