Hi John and Others,  I have found the source of my mystery noise. How do I 
post a report with pictures?  If I can do this on Larry's site, and that is 
the standard way to share pictures, would someone email me his www. so I 
don't send them to the wrong Larry?
Thanks, Ted  "Its a Happy Day"!!

I would be helpful to see some examples of this
noise.  Can you put an hour-long file on Larry's
site so that others can take a close look?

Also, a photograph of your sensor would be of interest.
