Yesterday I posted an article in the Random TV History thread from a long-gone Melbourne-based entertainment magazine called A-Z.
This is an article from another edition of said magazine, AM vs FM, from A-Z, 1 November 1984, just as AM was getting ready for Stereo.
Though 3XY was a bit cheeky promoting its Stereo AM in the same issue – a few months before the “official” launch which IIRC was to be in February 1985.
