The full range signal showed a latency of 2.2 mSec, the low passed signal showed a latency of 7+ mSec.

How can that be?

I use "auto delay" in ST class and sweep a low pass filter to demonstrate the effect.  It tends to get the uninitiated thinking in a different direction.

So are you going to leave us guessing?

At 100hz my sabine navigator goes to 3.05 ms from 1.50 ms for the full range signal using the delay finder. It is a difference of 1.1 ms using the IR.

My best guess is that it is a function of the wavelength and the fact that the longer wavelengths vibrate slower.

It's probably just a phase he's going through.
