BTW, what ever became of AM stereo?

It is still another proof that one cannot polish a turd.

I disagree with that statement. When I was a broadcast engineer, one of the
stations I worked for was AM. The entire transmitting system was capable of
15KHz audio. It sounded just like monophonic FM on the modulation monitor.
Unfortunately, radios that can adequately demodulate hi-fi AM are more
expensive, so there seems to be little market demand for them. Hi-fi stereo
AM is technically feasible, but its time is probably past. Most AM
broadcasters in the US have gone to all-talk formats, where hi-fi and stereo
are relatively unimportant.
