Hi Ted,

I took a look at your channel 3 posting, and ran the Winquake FFT
analysis on it.

Where did all the noise found at 4, 12 and 17 hz come from?

There is no peak at 0.2 hz, which is suspicious.

It looks to me as if a tremendous amount of noise is being recorded, but
I have no clue of the noise source.

Best wishes,  Roger
