1979 Harris AM Stereo demo LP (Side A)

Harris V-CPM was one of five AM Stereo broadcasting systems proposed to the FCC in the late '70s. In 1979, Harris put out this 45 rpm LP (also available on reel-to-reel tape) to demonstrate the performance and tout the advantages of their system.

The Harris V-CPM system was the most technologically advanced and arguably the best performing AM Stereo system, but it was also the most complex and costly to implement. In 1984, Harris modified their system to be compatible with Motorola C-Quam, which was becoming the de facto standard for AM Stereo, and began building Motorola-licensed C-Quam equipment for radio stations.

In 1993, the FCC belatedly chose Motorola C-Quam as the USA's single standard for AM Stereo broadcasting, after Australia and Canada had already done so in 1985 and 1988, respectively. Numerous C-Quam AM Stereo stations remain on the air today worldwide, but along with the Magnavox, Kahn/Hazeltine, and Belar systems, the Harris system has long since been rendered defunct.

Side B contains many music samples which will unfortunately have to be edited in order to avoid copyright restrictions. I also had to cut off the ending of this side due to a copyright restriction which would've blocked this video in some countries.

Gubmint dropped the ball on AM stereo by not picking a standard. Government is always wanting to do what it can't do instead of what it can. "All the rock stars want to act, and all the actors want to sing".

@MillBelater Actually, the FCC tried to pick a single standard for AM Stereo twice (first Magnavox, then Harris), but both times the proponents of the other systems complained loudly, especially Mr. Kahn. Even when the FCC finally chose C-Quam as the standard in 1993, Kahn was still fighting tooth and nail for his system, even though it had failed in the marketplace -- his system may have been superior in some aspects, but Motorola had the big money to make their system win.

Interesting! What kinds of receivers could do AM stereo? I don't remember many as I said, but my aunt and uncle had a stereo where the green light would activatewhen an AM station was detected, so that might have been stereo. It was a Sears AM/FM stereo with double cassette.

@manyvideoinerests Look up my web site AMStereo(.)s5(.)com (remove the parentheses) for a full list of AM Stereo receivers.

OMG... the little bit of soap song is EPICCCCCC!!!!

@century3horizons and yet WOWO today is a talk station running I think IBOC DAB. I can't tell exactly due to being on the fringe of their daytime coverage (Avon Indiana) and my HD Radio receiver being stingy. They actually did convert to Motorola C-QUAM later on and ran it for a good number of years.

@harleykman But guess what? In times where digital technology is implied, there is a war against you, the consumer. The corporations will destroy your liberties with copy protection, encryption, and controlling your method of consumption. Remember the forced ads on some DVDs?

[harleykman]

@MillBelater And yet now government has PICKED a digital standard, to try to avoid the mess that was AM stereo, and people are still complaining. The FCC can't win no matter what they do
