I drive the same route everyday. On the same 1.5 mile section I get a very
loud buzz and on top of the buzz a higher pitched periodic hum lasting for
10 seconds and occurring every 30 seconds overpowering everything on the low
end of the am band. There is a 3-phase distribution line along the road,
would a failing insulator create this type of problem, I thought that would
be more localized than covering a 1.5 mile stretch. Along this 1.5 miles I
travel 3 different directions and the intensity doesn't change much and it
doesn't make any difference what time of night or day. Near one end of this
area, there is a transmission tower of some type. The tower has been there
long before cell phone towers started sprouting like weeds, also it doesn't
have the dish array near the top just a straight tower, probably 15' sq. at
the base and 75' tall.

Is the person or company responsible for creating this type of interference
obligated to correct the cause?
