Barry told me to go look at the Orbitz web site and I did.
That ain't no punched tape :-).
First of all, there are no sprocket holes (small pre-punched holes
used in the mechanical days for sprockets to drive the tape, and in
later day readers to get a "clock" signal when passing the tape
through an optical reader).
Secondly, there are only three "holes" per column!
Each hole has more than one level of gray, though, so each column
of tape carries more than 3 bits of datum :-) :-).
How did Dxpeditions do RTTY in the Model 19 days?!
