VIA CERTIFIED MAIL - RETURN RECEIPT REQUESTED
September 28, 2009
Mr. Gary Palm
Operations Manager - Helena
Northwestern Energy
(address withheld)
Helena, MT 59604
Re: EB-09-GB-0027
Dear Mr. Palm:
The Federal Communications Commission contacted your company by letter
dated March 30, 2009, indicating that it had received complaints of
harmful radio interference possibly caused by power line equipment
maintained by your company. The interference was reported by:
(Name withheld)
(Address withheld)
Helena, MT 59601
Tel: (number withheld)
On June 5, 2009, you responded to the Commission detailing Northwestern
Energy's (NWE) efforts to resolve the matter and indicated that between
2003 and 2008, you repaired 215 poles and spent countless man hours in
attempting to resolve (name withheld)'s interference matter. You further
note that in late summer 2008 you executed a planned repair in (name
withheld)'s area in the hope that it would reduce his noise level. In your
letter, you explain that it was NWE's impression that the complained of
intermittent 18dB over S9 was no longer detectable and that (name
withheld)'s communication abilities were significantly improved. To
support that contention, you note that (name withheld) was able to
communicate with another licensed amateur in Germany. You did not ,
however, provide any details of recent attempts to resolve (name
withheld)'s noise. Rather, you noted that "NWE concluded that its
facilities were not adversely affecting the operator's ability to
communicate."
Such a response is not acceptable. (Name withheld) reports that as of July
1, 2009, the noise remains at S9 levels and has not decreased at all.
Contrary to your assertion, (name withheld)'s ability to communicate with
Germany is not indicative of an improvement in the "noise" level, but is
rather the result of his directional antenna. Should that antenna be
turned in another direction, the noise is again prohibiting his use of his
amateur equipment. Quite often in preparing a response to these letters, a
utility will indicate that they have spent countless hours attempting to
locate and correct "noise" in and around the residence of the amateur,
which is exactly what NWE is reporting herein. Unfortunately, those
sources of "noise" are not the noise that is causing interference to the
amateur. It is not the Commission's intent that the utility should correct
all sources of "noise" in and around the amateur's residence; rather, it
is our intent that you locate and eliminate the specific noise causing
radio frequency interference to (name withheld). In order to correctly
identify and then eliminate the source of (name withheld)'s specific radio
interference, staff from NWE will need to visit (name withheld)'s
residence and listen to the noise on his amateur equipment. Once your
staff has heard (name withheld)'s specific "noise," they will be better
equipped to locate and correct the specific source of his radio
interference.
To help you better understand your responsibilities under Commission
rules, here are the most important rules relating to radio and television
interference from incidental radiators:
47 CFR S: 15.5: General conditions of operation.
(b) Operation of an intentional, unintentional, or incidental radiator is
subject to the conditions that no harmful interference is caused and that
interference must be accepted that may be caused by the operation of an
authorized radio station, by another intentional or unintentional
radiator, by industrial, scientific and medical (ISM) equipment, or by an
incidental radiator.
(c) The operator of the radio frequency device shall be required to cease
operating the device upon notification by a Commission representative that
the device is causing harmful interference. Operation shall not resume
until the condition causing the harmful interference has been corrected.
47 CFR S: 15.13: Incidental radiators.
Manufacturers of these devices shall employ good engineering practices to
minimize the risk of harmful interference.
47 CFR S: 15.15: General technical requirements.
(c) Parties responsible for equipment compliance should note that the
limits specified in this part will not prevent harmful interference under
all circumstances. Since the operators of Part 15 devices are required to
cease operation should harmful interference occur to authorized users of
the radio frequency spectrum, the parties responsible for equipment
compliance are encouraged to employ the minimum field strength necessary
for communications, to provide greater attenuation of unwanted emissions
than required by these regulations, and to advise the user as to how to
resolve harmful interference problems.
In order to avoid enforcement action on this matter, you have thirty (30)
days from the date of receipt of this warning to respond to this office at
the following address: 1270 Fairfield Road, Gettysburg, PA 17325. The
response must contain a statement of when you visited (name withheld)'s
residence and after that visit, the specific action(s) taken to identify
and eliminate the source(s) of (name withheld)'s radio interference. If
you have any questions about this matter, please contact me at
717-338-2577.
Sincerely,
Laura L. Smith
Special Counsel
