Hi Jim,  At night time the noise stops as suddenly as it begins, I think =
it stops at around 4:30pm, starts at 8:35 to 8:50am.  Really quiet at =
night,
I live 1/4 mile from a school, and crossing lights, but the noise =
continues during Sat, Sun and Holidays when the school is inactive.  I =
live 1 1/2 miles from a fire station.
I did remove the magnet during the noise, and the trace was dead quite, =
all the noise stopped and started again when I replaced the magnet over =
the coil, so I don't think it is RFI.  During the night time, and day =
time I do record earthquakes, so I know the sensor is working.
The list of things it is not continues to grow;  It is not the sun, =
clouds, weather, home appliances, TV, our telephones, wind, =
construction.

So Now I think it is vibrations coming from somewhere during the day =
time only.  The spikes are random, sometimes one, two min group per =
hour, then a quiet hour, followed by groups lasting 10 mins and 10 mins =
of quiet.  Some hours are filled with spikes. No patterns.
Everything follows what you would expect with auto traffic, but I =
watched carefully on Thanksgiving and the noise took no holiday.=20
I live about 4 miles from the interstate highway.
Whatever it is, I know I will have to put up with it, unless its =
something in my house.  Thanks, If I ever isolate it I'll let you know.  =
Ted
