Thanks for the plug, Steve! QST seems to like my no-so-cookie-cutter
reviews. Hopefully you all do, too.
The 880 review starts off with a very brief mention of the transition from
AM to SSB. That took place in Amateur Radio beginning around 1949 (the year
I was born), and was still in process in 1965 (the year I got my ham license).
In doing a little research, I learned that SSB was originally created for
long distance telephone use, for things like the Atlantic cable as Adam
notes, in the early 1930's. It first appeared in Amateur Radio
experimentally in 1947. QST began running regular articles about it in '49.
Heresy? I think that's a reference to the way AM ops dismissed the "Donald
Duck" talk, which is being echoed today by hams suspicious of digital voice.
Same as it ever was...

Hi Steve,
I am not 100% sure about the dates cited, but where was the heresy? The 9 dB
power advantage of SSB over AM, and the 50% reduction in occupied bandwidth
when using SSB, are indisputable (at least from my perspective).
Germany had a working public SSB radio-telephone link between New York and
Berlin as far back as 1931.
