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.
