Nice! Wiese and Varstahl, those high quality and cleaned up versions of the codes help so much! 
'DO QKO OTT'
'IE TOE EWW' |
What I noticed is that the second part when reversing dot/dash makes some bit of sense. For example, OTT reversed in morse is SEE. At this point I'll go out on a limb and declare that part a "DO YOU SEE?". How to get that though… But it would make sense, as even that is a reference.
But I'm more worried about the "Listen to the ghosts". It seems clear that there actually IS something in the audio track we didn't quite get. I'll try to get back to it, maybe download a better version of the audio, we'll see. I did again but I think they're just referring to the white noise. Either that or I'm unable to extrapolate/isolate properly.
