npub1l3gpk6vrudg8r67swqlex5alv9ch59s4lw46kk6hekuxe2n3aczsyqvu48 (npub1l3g…vu48) I was thinking you'd need either quaternary, or pairing up bits to symbols, but no.
The carrier is a binary on or off. We don't care about it's level. We care solely about it's timing. Therefore the only information you need is "was the carrier present at this time" because if you have enough timing samples you can decode the pattern. So no it could be a flat bitstream. You sample at a constant rate, outputting a 1 for carrier presence and 0 for carrier absence. As long as the sending WPM isn't too high for your sample rate, Morse is encodable as a binary stream.
