```Hi Bob,  To me the noise appears as if you turn on a light switch =
on/off/on/off this goes on two mins?, other times it continues for 30 =
mins?, it may then stop of 10 mins, and the whole thing start again.  =
Here is a funny but maybe meaningful thing.  Quiet all night and at =
8:35, 8:37 sometimes as late as 8:50am the noise starts, it last about 8 =
mins, stops for maybe 15 mins.  No pattern except for the start time.  I =
also notice the hours of 1:00 pm and 2:00pm seem to have the most noise. =
Like magic around 4:30 tp 5:00pm sometimes 6:00 all goes quiet.
I thought it was the sun warming the house, but it does it sun or =
clouds, overcast, warm or cold, week day and holidays.
Tomorrow, I think I will drive around and look for road construction =
equipment, maybe they are working on weekends and holidays to complete a =
project.  Does anyone know how close construction would need to be?      =

At the risk of repeating questions that has already been asked -

=20

How sharp is the onset of noise - are there periods where you can see =
it build up and then slow down or quit, or is it like when you turn a =
switch on or off?

=20

Have you correlated the noise with weather conditions - such as =
overcast or minimal sun as opposed to bright sunny days?

Hi Chris, You know these are great suggestions....I can't rotate the =
sensor, where it is located, but if I could???????

I do have another sensor I could set up and rotate.  I could perhaps =
setup a microphone/ amp/ headset, to see if I could pick up the noise =
and then isolate its direction.  I tried the am radio but could not hear =
the noise, I will try that again, at different frequencies.   Ted
