According to my analysis of .wav recorded directly from the MC-1000 MIC port, each short (bit 1) wave (1 peak + 1 valley) takes about 16 samples at 22050 samples per second. That gives 5512.5 waves per second. The long (bit 0) wave is twice as long, so half the frequency. Then, if my calculations are right:

short (bit 1) wave: 5512.5 Hz
long (bit 0) wave: 2756.25 Hz
