Re: a few new ones...
As for the first one, it has no serious lowpass, so I'd say it's likely pre-broadcast. I've seen prefm material that looks like this, too.
Second one looks like post-broadcast and might or might not be lossy sourced. Something like "mp2 or not > fm/tv (> ana?) > digi" for example. Can't tell at all at this resolution, please try increasing the window size for the spectral view from 64 to 256 No members have liked this post.

Re: a few new ones...
the "bs1983-11-04" (sabbath?) looks like 1) an FM (red stripe aka carrier) and 2) like it has been speed-corrected (perfect black at the top). Doesn't look like prebroadcast since it has the stripe, but ssamadhi97 says he's seen them look like this before... I can't say I have. Can't really say much more, would like to see a better SA zoomed to 2 seconds. if you wanna yousendit a clip to five at ttd dot com feel free.
"ther93-04-03" I'm not sure about... could be lossy, could be 32k DAT likewise, I would love to check a sample of this that I could zoom around on and listen to.

And this bs show looks like it still has some signal going on above 16kHz, that's what makes me think it might be pre-broadcast. btw iirc ~16kHz tone indicates tv, not fm. No members have liked this post.
