[RFI] If you're ATT, you can do something about RFI...

[Dave Harmon]

Hi Dale......
Interesting......for the last year and a half I have been forced off the air
due to terrible power line noise that I can easily locate.
The power company cannot fix it for some reason....these people are truly
lame.
I have done everything I can think of.
Hopefully....this will be fixed at some point in time....that's why you
haven't heard me on the CCA Midwestern net.

Tom, 

I suspect that your post will generate several replies.  Mine is as follows:

1.  Amateur radio is also a LICENSED service.  We CAN invoke the FCC, but
admittedly, it takes several more steps to get action than what AT&T had to
do in Houston.  It should be noted that 705 MHz DOES fall within the range
of controlled emissions for Part 15 devices, whereas 3.5 MHz does not. 

2.  This case seems to be pretty much like the situation hams face when a
neighbor has a plasma TV or touch lamp or battery charger that are
incidental radiators and cause grief to radio systems.  FCC may not do
anything about radiated interference on HF because of non-coverage under
Part 15, so you, the ham, then have the option of confronting the neighbor
directly about an offending device; the result is often similar to what the
defendant in this case is doing to AT&T.  The difference is, of course,
he'll probably lose.

3.  The one area in which FCC has gone to bat for hams has been with the
electric power companies when the interference can be shown to emanate from
distribution power lines and associated equipment.  I have had two
situations, one in IL and the other here in IA, in which the local power
company was very helpful and even quick in fixing severe RFI problems that
were affecting me.  I did not invoke FCC, but I think the power companies
were well aware of the sort of pressure or fines that can come from amateur
radio RFI complaints.   

4.  The situation here is not related to power distribution problems, and
neither are plasma TV or other consumer garbage RFI sources, so I suspect
that the fact that the light fixtures are putting out big sigs on 705 MHz is
a huge help for AT&T in getting action.  Incidentally, it sure would be
interesting to learn just how devices made to operate at relatively low
frequencies can generate strong harmonics or spurs way up into the UHF
range.
