Hi Ed, just as a point of comparison, I've explored the envelope of our 320 (small tail) right up to the red line with no vibration or other adverse characteristics present. Could it be a gear door being pulled open just a little by the high speed air flow? If so maybe the air in the gear cavity resonates at a low freq kinda like blowing over the top of a coke bottle. Just a guess.
