Can you hear it on the AM broadcast band?
If so use the ferrite rod antenna to get directions of it and have
yourself a fox hunt.

Hi Dave,
If the noise came and went sharply (like someone turned something off
for a week), and "man made" sounding, perhaps one of your neighbors
put up a solar power array? Lots of diodes and the power inverter
running during the day...
Just a thought,

there is a possibility that you have a nearby electrical transformer
that has a corroded connection on it, these connections can be a
major source of noise and they will come and go with changes in
humidity or precipitation. will it suddenly stop at times are is it
a fairly constant level?
your local utility company can find and repair these connections but
they need a better idea of the direction it is from your QTH.
Those are my thoughts on your problem
Good Luck
