This was the Kahn system and it is no longer legal for transmission of stereo 
AM in the USA.  The Motorola CQUAM system uses a low frequency pilot tone and 
an FM modulation of the carrier to send the L-R information.
  
Why are we discussing AM stereo in this echo?  If anyone wants to know more, 
hop up to BROADCAST where this discussion makes sense!
