That is my recollection as well. SITOR is very much alive and well,
AMTOR, maybe not so much, amateurs tend to move on, sometimes but not
always ahead of the pack. :-)
NAVTEX is also alive and well, 518 Kcs, I think.
Modes I remember but are more or less moribund: AMTOR, HF AX.25 pa, AM.
Modes I don't know anything about: Olivia, anything with more than 3
tones, and everything that starts with "JT."

"Amtor" existed long before it was a legal mode on
Amateur radio as "SiTOR", (Simplex Teleprinting
over Radio" ) on commercial maritime circuits. To
my knowledge, there is no basic difference between
Sitor and Amtor. Only the name is different.
