You assume our antennae and our hull are at the same depth, they
aren't. Underway we stream a buoy above/behind the boat that carries
our antennae.

i.e. it made a 300 baud modem look fast. So, assuming 30 bits/second, or
roughly 4 ASCII characters/second. 240 characters per minute.

Hm, yeah, I guess that's higher than I initially thought.


It wasn't ASCII, it was alphanumeric teletype code.

30 bits/sec = 6 chars/sec = 360 characters a minute.
360 chars/min *60mins/hour *24hours/day = 518,400 chars/day.

Not much by 'modern' standards, but a half a meg of text is a
substantial chunk. Even more when you consider a goodly number of the
'words' are actually abbreviations.
