Re: C-QUAM AM Stereo MOD'ed AM Radio Shack portable, and AM Station semi-tour VID.

There are a lot of good AM stereo videos out there, eye candy, porn for engineers, with the Harris transmitters and stereo exciters, just beautiful. Look out for tours of KYET and WION 1430 and see inside of the stations and find out how AM stereo works, C-QUAM.

That Radio Shack portable, it was apparently officially modified by techs at Motorola themselves, as a monitor, demo radio for the C-QUAM system, with external speakers to spread wide apart and hear the effect.

In fact, that very radio was one of the models suggested to modify with an AM stereo decoder board in the old Radio Electronics article, written by a Motorola tech and introducing AM stereo to readers, mid-1980s!
