SOS is usually sent as a prosign, i.e. a single dit
between tones?

I have never heard that is was sent as a prosign, but IMHO it would sound
weird.

Back in 1949-1950 when I got my first ticket as W8EZE and became the trustee
for the Walnut Hills High School amateur radio club in Cincinnati, the club
had one of those World War Two devices to be used in lifeboats, with a crank
on top, which you held between your legs while turning the crank. It had an
antenna terminal to which we attached a dummy load. It had no other controls
or terminals, just the crank and an antenna terminal. I think it only put
out a few watts. Listening on 500 kc/s (as we called them, in those days)
on I think a BC348 receiver, while turning the crank one heard
. . . _ _ _ . . . (long space) . . . _ _ _ . . . (long space), and on and
on, as if you were sending one character with nine components, over and over
again. You could write it as
___
SOS
the same way one can write
__
BT
for a double dash, or
__
DN
for a fraction bar (forward slash).

it was orange
It was called a "Gibson Girl"
