No, the January 1977 issue of Ham Radio magazine, it was the

I could never really make sense of the article. My recollection
is that it didn't do a good job on conveying the theory to
the average ham, or even the purpose of such a mode,

I would think it would be for the same reason as SSB for AM? To achieve
half the bandwidth utilization for a given signal? (But at the expense of
3dB poorer SNR...)

It's been quite a few years since I looked at the article. There was
just something about the article that seemed like I'd been dropped into
something. Maybe the style was different from most articles in the
magazine, maybe because it didn't really seem to be a practical article.
There just seemed to be something missing. Yes, it would take up less
space, but then why not go to some other mode? It's the only time I've
seen something on the subject, and I think it could have better been handled.
