SWL's Can File BPL Interference Complaints
Part 15 prohibits interference to licensed services from unlicensed
devices, but do you need to have a license yourself to complain about
interference? Can SWLs complain to the FCC if they receive interference
from BPL systems?
Yes, they can, with limited exceptions, according to Chris Imlay W3KD, ARRL
General Council:
"There is no doubt that international broadcast listeners have standing to
complain about interference to the reception of foreign broadcast signals.
One does not have to be a licensee of a transmitter in order to receive
harmful interference from a United States based RF source and have standing
to complain about it. No shortwave listener to a United States
international broadcast station can complain because they are not in the
target audience, but interference to non-U.S. based SW transmissions are
fair game.
The FCC and court cases on standing to file various petitions, etc. with
the FCC are complex, but the cases are clear that the allegation of
suffering actual electromagnetic interference to reception of a broadcast
service, even one generated internationally, from a domestic RF source, is
sufficient in every case to demonstrate standing to file a complaint."
Further, ARRL Dave Sumner K1ZZ points out that International
Telecommunications Union Radio Regulations require member nations to
protect HF communications from harmful interference:
RR 4.11 reads: "Member States recognize that among frequencies which have
long-distance propagation characteristics, those in the bands between 5 and
30 MHz are particularly useful for long-distance communications; they agree
to make every possible effort to reserve these bands for such
communications. Whenever frequencies in these bands are used for
short-range or medium-distance communications, the minimum power necessary
shall be employed."
RR 15.12 reads, "Administrations shall take all practicable and necessary
steps to ensure that the operation of electrical apparatus or installations
of any kind, including power and telecommunication distribution networks,
but excluding equipment used for industrial, scientific and medical
applications, does not cause harmful interference to a radiocommunication
service and, in particular, to a radionavigation or any other safety
service operating in accordance with the provisions of these Regulations."
The US is an ITU member nation, of course.
