It was much slower than that when I worked on submarine receivers in the early / mid 80s. 1 5-bit baudot character every 5 seconds.

- defrost 4y agoThere are levels to how much you can push given atenna sizes and amount of gear at either end - the submarine rates are the basic most reliable with least equipment type of transfer rates (as I recall - I was literally barely a teenager at best at the time and learning radio | electronics | etc for the fist time, after which I went more into a theory direction). It would seem I was recalling frequency-shift keying modulation rates: https://en.wikipedia.org/wiki/Very_low_frequency https://en.wikipedia.org/wiki/Very_low_frequency which may not have been used to communicate to submarines.
