I believe it was the same cut on AM and FM.
Listeners were in a car.

I can't speak to the exact freq response
of AM stereo, although it was, at least
on my radio, wider than standard AM.
But, then again, what we as professionals
call fidelity may NOT be what listeners
prefer for their audio. While I am definitely
for putting out as clean a sound as possible,
it is also true that no successful radio station
really has more than a 10 15 dB dynamic
range. Can't be. It would "disappear" in
a car during operation.

Agreed. It was past of a "truce" in the Modulation
Wars - which the tech community should
never have stood for.
