[net.audio] Quad FM ?

mat@hou5e.UUCP (07/07/83)

According to an article in the 7/7/83 Red Bank Register

	The FCC, w/o fanfare, and pe'rhaps too late [ ... ] authorized
	FM radio stations yesterday to broadcast in four-channel,
	quadrophonic sound.

	... with a simple one-page order, the FCC announced:  ``The
	quadrophonic FM broadcasting systems described in the quad notice,
	and any other compatible quadrophonic transmission system, may
	now be used by FM broadcasters.''

Well, it almost certainly is too late.  But, for my curiousity, how did this
FM system work?  Would it be incompatible with the FM subcarrier usage now
planned for radio pagers and the like?  And, BTW, do the pagers interfere
with ``high-quality'' FM broadcasting, especially as done by the better
classical music stations?
