I don't thing the F.C.C. does much of anything about interference any
more.
One block from my house is a guy with a 50' tower and a very large
amateur
radio beam antenna.  Every night people for several blocks around can
not
watch TV because of his transmitter.  Many people have complained to him
and
the FCC including me.  We all received the exact same form letter and
questionair in the mail from the FCC.  Over 100 people complained and
nothing has happened at all.  The FCC new policy is to have the person
or
persons that file the complaint do all the investigation work.  Then and
only then will the FCC check into it.  The questionair from the FCC asks
things like the persons name,  model number of the radio they are using,
how much power are they using, what is the serial number of the
transmitter,
what is the manufacture of the antenna, what is the manufacture of the
transmitter, what is there frequency, what is there call letters, most
of
the questions can not be answered so nothing gets done.  Many people
have
talked to him about it but he doesn't seem to care that his transmitter
over
powers everyone TV and radio.  For 3 years people have put up with this
and
most have connected to cable TV now because they can not watch regular
TV
any more.  About 6 months ago someone connected a truck or something to
his
antenna in the middle of the night and pulled it down and left it in the
middle of the street in a tangled twisted mess.  He hasn't put it back
up
yet.  The problem is solved for now, no thanks to the FCC.
