BTW SSB is probably 30 or 40 years old.


SSB first showed up in the ham bands in 1934.


How many sidebanders were active then? A thousand? A hundred?
A dozen? Two?

AT&T had SSB running
around ten years before hams did.


1928 on radio. See the "Collins Sideband book" for references.

The Dutch beat us Yanks on establishing regular commercial SSB
for messaging.

"Sideband" was used earlier in wired communications, called "carrier"
equiment for long-distance service using open-wire lines with four
voice circuits per wire pair.

Next year will mark the 70th
anniversary of ham SSB. Gawd I love these "new, modern modes" like SSB
which make Morse such an artifact mode . . .


Morse code *IS* an artifact, old Artifact.

Morse code was first used for commercial communications in 1844.

1844 is 159 years ago. Morse is over twice your age.

All the other communications services in the world have dropped morse
code modes.

Morse code survives only in a part of amateurism, a virtual life
enjoyed by those who wanted very much to be "pioneers" but never
could due to being born so much later after morse code's birth.
