An explanation of how the system worked went out in the IBA weekly “digest” for the TV & Radio trade at the time, a copy of which is on YouTube:

Thank you for that reply Nodrog.

I recall seeing an edition of Engineering Announcements on YouTube which featured AM stereo hut as you say it never really got beyond testing. I never saw AM stereo receivers being available, and thinking back the best way to introduce AM stereo would probably have been through car radios.
