The spectrals are all over the place on this one. There looks to be frequent blocking around the 16-17 kHz mark :(

Well, it was an FM broadcast

Fair. I usually associate blocking with MPEG artefacts, but they aren't audible in the actual recording, so it might be a lossless recording of an FM broadcast. It's hard to tell, hence why I posted it here.
