I've noticed something else on this problem, below the 3-phase electrical
conductors, there is either a telephone or catv wire. The intense periods
occur when I drive by some type of device that loops this cable in to a pear
shaped configuration. I guess it's not a periodic sound but appears that way
because they are evenly spaced and I drive the same speed.
Maybe if anyone is still following this thread and that sheds anymore light
they'll respond.

It depends.

If they're radiating RF in excess of FCC part 15 limits, and do not
have a license to transmit in whatever frequency band they are using,
then they're very probably obligated to fix the problem or to shut
down whatever equipment is radiating.

If they're transmitting in a frequency band / allocation for which
they have a proper license, and if their transmission isn't leaking
spurious frequencies in excess of the FCC limits, then they're
probably quite legal. In this situation, what you'd hearing would be
considered to be "undesired reception" - that is, your car radio is
being overwhelmed by a strong signal outside of its normal passband -
and the FCC would consider this the fault of your radio.

Without doing some spectrum analysis and direction finding it's hard
to distinguish the two from the symptoms you report.
