I need help with an irritating noise problem.  My neighbor
and myself receive an intermittant signal on our TV and
FM radio (I don't know about AM).  The signal produces a
band of small white dots on TV, and a buzzing sound on
the radio.  It can be seen on a number of TV channels.
It also occurs on a portable radio held outside
my house, so I don't think it is in the AC power.  The
noise also seems to occur without any pattern that I
would associate with a ham radio, although I can't rule
out that possibility.  I have some power lines behind my
house carrying residential power, and also a transformer
on a pole back there.  

Can I track down the noise source with a portable radio?
The radio has one of those telescoping antennas.  If I
could get the noise to sound louder when I hold the antenna
in a certain position, how do I know which direction the
noise is coming from?

I would appreciate any advice.
