Harvey: The seeming peak at the bottom of the slug has a much lower
signal-to-noise. Go back to the top. Unfortunately, it is difficult
to find the peak at the top because the response is extremely flat.
The best way to see the peak is by connecting the audio output
(across the speaker) to an analog AC volt meter (low scale setting).
You can see the peak quite clearly with this set up. But you can
probably see it fairly well using Spectrogram, also. Anyway, the
peak you want is near the top where the signal-to-noise is best.
best wishes,
