I forgot to mention, in the flowgraphs I winged up:
a) I might have the sense of 0 and 1 symbols reversed. Right now I have
0 symbols as the low frequency and 1 symbols as the high frequency, but
that guess could be wrong. (The convention for AFSK systems is usually
the reverse of what I have, for example.)
b) I'm assuming the data bits are not differentially encoded or NRZI
encoded. That could be wrong. AIS uses NRZI, for example.
