I think that the article is wrong in the consept of modulation. I recall
that the stereo is modulated not in depth and with but on each side of the
track. So he should be wrong on the demodulation itself, missing the channel
splitting. I guess he could hear something like (Left+Right)*cos (x) and
not the proper left or right channel.
Anyway, I would be glad to send over some old stuff to see what he can do
about them ;-)
