I don't know, but it sounds somewhat reminiscent of a "sweeper" type of mystery signal that I've heard recordings of before. 
If you speed it up to several hundred times normal, you can see a definite set of multiple downward-sweeping tones that overlap each other, repeating over and over.

Looks like sixteen different 'tones' or frequency 'slots' at any one time (in the recorded BW anyway) viewing an audio spectrogram that's updated in real-time as the audio is being played, and the tones slowly all 'drift' down (linearly seem to shift) in frequency (as Seamus observed using high-speed playback) ...


The fading may be due, at least in part, to fading/selective fading. The actual signal may be 16 tones.

I'd say propagation experiment, or a new analysis tool for evaluating a 'path' ... can't say that much data is being moved this way, but it is possible it's a comms taking place, although I have never seen a 'standard' that used drifting tones like these ...


Here's what Spectran shows:

o 1/2 wave 80m Dipole used with several tuners
o Tuned loops from 2' thru 16' diam. capable of 160m thru 10m

It does sound like feedback; as anyone who has worked with an SSB link and had their audio 'brought back' through another means (like land-line or another radio link as for testing a radio 'circuit') and allowed some of that 'audio' to enter the SSB link for anther go-around can testify ...
