As for the tone you called "carrier", I suspect we're simply looking at some kind of TV source here (remember, horizontal scanning frequency is ~15750Hz for NTSC)
CLIPPING! yes, thank you. take a look at the spectrum matching the waveform where it would clip.

So, broadcast FM or PAL > WAV file? > encoded mp3 > WAV (recorded too high introducing clipping spikes) > flac.

I assume this is the progression, since the mp3 would remove the clips if they were in the original WAV file.
