Re: lossy or normal for FM?

Oink is wrong.

MP3 is lossy data compression that purposefully discards audio to save space. Who needs to save space anymore?

FM broadcasts are not lossy. They may roll off at 15kHz, but the audio below that is not lossy. Many stations compress the dynamics of their audio to compete with road noise in cars, etc (some do a terrible job of it, some do it well), but in 1979, it was as good as you could get. The spectrum roll off here is not because of the FM transmission system, it's because the source was lo-fi satellite or because the cassette wasn't full range, as Five said.
