Block diagram of the Harris AM Stereo system. This is the "sliding pilot tone" version; as the footnote indicates, it was later modified to use a fixed pilot tone frequency, as otherwise the receiver design was too complex to be practical.

"Harris AM Stereo System Faulters" as described in an August 1983 newspaper article in the "Toledo Blade". Talks about how use of the Harris AM Stereo system was temporarily halted due to technical issues, which took Harris out of the lead and allowed the Motorola and Kahn systems to become more successful.

ndxe-ad.jpg
An advertisement for NDXE, a shortwave station which was going to transmit in Kahn AM Stereo. The 1986 edition of the World Radio/TV Handbook has this full-page ad on page 45. Unfortunately, NDXE never got on the air, and since then, no other station has had such strong interest in the use of AM Stereo on the shortwave band.
