SUPPLEMENTARY INFORMATION:

OMB Information Collection Notification

The Federal Communications Commission, as part of its continuing
effort to reduce paperwork burden invites the general public and other
Federal agencies to take this opportunity to comment on the following
proposed and/or continuing information collections, as required by the
Paperwork Reduction Act of 1995, Public Law 104-13. The NRPM has been
submitted to the Office of Management and Budget for review under
Section 3507(d) of the PRA. Comments are requested concerning (a)
whether the proposed collection of information is necessary for the
proper performance of the functions of the Commission, including
whether the information shall have practical utility; (b) the accuracy
of the Commissions burden estimates; (c) ways to enhance the quality,
utility, and clarity of the information collected and (d) ways to
minimize the burden of the collection of information on the
respondents, including the use of automated collection techniques or
other forms of information technology.
OMB Control Number: None.
Title: Proposed Section 73.1630 Blanketing Interference.
Form Number: None.
Type of Review: New.
Respondents: Broadcast Licensees.
Number of Respondents: 21,000 Complainants.
Estimated time per response: The burden ranges from 1 hour to 2
hours.
Annual Burden: 41,000 hours.
Total Annual Cost per Respondent: 0.
Needs and Uses: This rulemaking proceeding proposes to provide
detailed clarification of the AM, FM, and TV licensee's
responsibilities in resolving/eliminating blanketing interference
caused by their individual stations. Under the current rules (Section
73.88 (AM), Section 73.318 (FM), Section 73.685(d) (TV)), the licensee
is financially responsible for resolving complaints of interference
within one year of program test authority when certain conditions are
met. After the first year, a licensee is only required to provide
technical assistance in determining the cause of the interference. In
this NPRM, we are proposing to consolidate all blanketing interference
rules under a new Section 73.1630, Blanketing Interference. This new
rule is designed to facilitate the resolution of broadcast interference
problems and sets forth all responsibilities of the licensee/permittee
of a broadcast station. For one year after the broadcast station
commences program tests, the licensee is financially responsible for
resolving blanketing interference complaints. After the first year, the
licensee is obligated to provide technical assistance to resolve
complaints of blanketing interference. The information provided to
complainants will be used to facilitate the resolution of complaints of
blanketing interference.
This is a synopsis of the Commission's Notice of Proposed Rule
Making in MM Docket No. 96-62 adopted March 21, 1996, and released on
April 26, 1996. The complete text of this Notice of Proposed Rule
Making is available for inspection and copying during normal business
hours in the FCC Dockets Branch (Room 230), 1919 M St., NW.,
Washington, DC, and may be purchased from the Commission's copy
contractor, International Transcription Service, Inc., (202) 857-3800,
2100 M St., NW., Suite 140, Washington, DC 20037.

Synopsis of Notice of Proposed Rule Making

1. This proceeding is initiated, on the Commission's own motion, in
order to clarify to what extent broadcast licensees are responsible for
eliminating blanketing interference caused by their individual
stations. In addition, this action is taken to refine and specify
methods for determining the geographical blanketing area. In many
cases, the licensee's responsibility in eliminating blanketing
interference is misunderstood by listeners and broadcasters alike.
Thus, the objectives of this action is intended to remove confusion and
facilitate the resolution of broadcast blanketing interference
problems.
2. Receivers are designed to operate in an environment consisting
of desired and undesired signals. As long as the levels of the signals
remain within the design specifications of the receiver, it will
operate in a predictable manner. If any of the signals in the
environment exceed the design specifications of the receiver, the
receiver will begin to operate with unpredictable results. In addition
to broadcast receivers, as mentioned above, a wide range of electronic
devices can suffer blanketing interference from the signals of nearby
radio and TV stations. For example, we are aware of problems with
telephone equipment (including answering machines, hard-wired,
cordless, and cellular telephones), hi-fi audio amplifiers, public
address systems, electronic music keyboard instruments, professional
studio and home recording components, and electronic medical equipment.
Currently, however, protection of these devices are not the
responsibility of the broadcast licensee.

Blanketing Interference Contours

3. Section 73.88 currently requires licensees of each AM broadcast
station to satisfy all reasonable complaints of blanketing interference
within the 1 V/m contour. Unlike the rules for FM, which define the
method of calculating the blanketing contour, no such method is
specified for AM. Thus, the licensee may find it convenient to
determine the 1 V/m contour by field measurements. As an alternative,
determining the AM blanketing contour mathematically for a single tower
antenna may result in a close approximation of the measured contour.
Determination of the AM blanketing contour from multi-tower directional
antenna arrays, however, may need to be calculated with near-field
considerations.
4. In continuing to use the current AM blanketing contour, we
propose that for directional antenna array systems, the determination
of the 1 V/m contour along each radial direction should be by actual
mathematical vector summation of the field radiated by each antenna.
Since this approach may require near-field considerations, we believe
that a more realistic determination of the 1 V/m contour AM blanketing
area would be reflected with this method. Therefore, we propose to
amend the rules for the method of calculating the blanketing

[[Page 26493]]

interference contour for AM broadcast stations as presented under
proposed Section 73.1630(a) below.
5. Because many of the transmitting antenna signal characteristics
and structural locations are the same for both FM and television
broadcast stations, we are not aware of any apparent reason, at this
time, not to utilize for television stations the same blanketing area
contour currently used for FM stations. Therefore, for regulatory
consistency, we propose to amend the rules by specifying that the TV
blanketing area be defined by the 115 dBu contour, as presented under
proposed Section 73.1630(b) below.
6. When the 115 dBu contour was originally proposed for FM
blanketing in BC Docket No. 82-186, most of the commenters agreed with
its use. Now that the industry has had much experience with this
contour level, we seek information as to whether it continues to be an
appropriate contour for defining FM blanketing areas, and should be
extended for defining television blanketing areas. In addition, because
the 1 V/m contour used for describing the AM blanketing area was
established at an even earlier period than the FM blanketing contour,
we seek information as to whether the 1 V/m contour continues to be an
appropriate contour level in today's radiofrequency environment.

Licensee's Responsibility

7. Under the current rules, which we propose to continue, the
licensee is financially responsible for resolving complaints when all
three of the following conditions are met: (1) The complainant's
affected device is located inside the station's blanketing contour; (2)
the complainant filed notice to the station within the first year of
program test authority; and (3) the interference is not to electrical
devices excluded from protection by Section 73.318(b). When these
conditions are met, the licensee must provide effective technical
assistance in determining the cause of the problem and advising on
corrective measures. Resolution of such blanketing interference
complaints may involve the installation of electrical or electronic
filters and traps, or the replacement of the complainants' affected
equipment, and these efforts are at the licensee's expense and without
cost to the complainant. If an otherwise valid complaint is lodged
after the one year period, the licensee is only required to provide
effective technical assistance in determining the cause of the problem
and advice on corrective measures; the licensee is not financially
responsible for any necessary corrective equipment or measures. If a
complainant is located outside of the blanketing contour area and files
after the one year period or the complaint involves devices and
equipment excluded from protection, the licensee has no obligation
under our rules to resolve the interference problem. However, as noted
earlier, many licensees take voluntary steps to assist in alleviating
the interference to promote goodwill within the station's community.
8. To give broadcast licensees further detailed guidance in
resolving blanketing interference problems, we propose to publish in
the rules an outlined summary of the station's responsibilities. We
propose that the licensee responsibility will vary depending on (1)
whether or not the complaint was filed within the first year of
operation, (2) whether the complainant is located inside or outside the
blanketing contour, and (3) whether the device experiencing
interference is covered under the blanketing rule.
9. Additionally, we note that in today's highly transitory society,
neighborhoods may have many residents move in after the initial one
year period specified in the rules. Further, the proliferation of new
communications services and technology may bring into established
neighborhoods many new devices subject to blanketing interference.
Therefore, we seek comment on whether the Commission's rules should be
modified for situations when blanketing interference occurs after the
one year period. Further, we seek comment on whether locations of
temporary lodging or transient residences, e.g., hotels, university
student dormitories, and rental properties should be subject to the
blanketing rules beyond the one year limit. In other words, we seek
comment on whether a station's obligation ends with that initial group
of complainants that files within one year, or whether the station's
obligation should extend to subsequent residents. Further, we seek
comment on whether these types of cases should be considered on a case-
by-case basis.

Effective Technical Assistance

10. Section 73.1630(d) of the proposed rules states, ``[f]ollowing
the one year period of full financial obligation to satisfy blanketing
complaints, licensees shall provide technical information or assistance
to complainants on remedies for blanketing interference.'' The rule
requires that a licensee provide information and assistance
sufficiently specific to enable the complainant to eliminate all
blanketing interference and not simply that the station attempt to
correct the problems. Effective technical assistance entails providing
specific details about proper corrective measures to resolve the
blanketing interference. For example, licensees may provide
complainants with diagrams and descriptions which explain how and where
to use radiofrequency chokes, ferrite cores, filters, and/or shielded
cable. In addition, effective technical assistance also includes the
recommendation on replacement equipment that would work better in the
high radiofrequency fields. We note that the licensee may authorize a
consultant or service company to provide this information or
assistance. However, effective technical assistance is not rendered
merely by referring the complainant to the equipment manufacturer.

High Gain Antennas

11. Section 73.318(b) specifies the conditions under which
licensees and permittees must satisfy complaints of blanketing
interference. It states, in pertinent part, that ``[t]hese requirements
specifically do not include interference complaints resulting from
malfunctioning or mistuned receivers, improperly installed antenna
systems, or the use of high gain antennas or antenna booster
amplifiers.'' It has been our experience that high gain antennas have
not been a factor in blanketing interference problems. Therefore, we
propose to delete reference to high gain antennas from our blanketing
rules and seek comment accordingly.

Telephone Interference

12. A great number of blanketing interference complaints are
submitted because of interference to telephones. The Commission's
blanketing rules, however, do not currently require broadcasters to
resolve telephone interference. Hard-wired telephones are considered
non-RF devices under the current blanketing interference rules and
thus, are excluded from protection per Section 73.318(b). Cordless
telephones are covered by Part 15 of the Commission's rules and thus,
Section 15.5(b) states, in pertinent part, that cordless telephones may
not cause harmful interference and that interference to cordless
telephones caused by the operation of an authorized radio station must
be accepted. Portable and mobile cellular telephones are RF devices
licensed under Part 22, Subpart K, and are considered as mobile
receivers, and thus, not protected by the current blanketing
interference rules. Because cell sites are fixed locations, however,

[[Page 26494]]

they would be protected from blanketing interference by the
Commission's rules.
13. We are concerned about interference to all telephones and
wireless devices, including interference that may develop in future PCS
and specialized mobile radio (SMR) systems. Therefore, we seek specific
comment on the following questions:
a. Should the Commission require broadcasters to resolve
interference to telephones, either hard-wired or wireless?
b. If so, to what extent should broadcast licensees be responsible
for resolving the interference? The Commission found, while conducting
the telephone interference survey, that filters are not always reliable
in eliminating residential telephone interference. Thus, if such
filtering devices are ineffective and licensees are not required to
furnish them, to what extent should licensees provide other technical
information and assistance?
c. Should the Commission rely on industry voluntary efforts to
implement interference free design standards for telephones, or should
the Commission initiate a separate rulemaking proceeding to consider
imposing higher interference immunity standards for residential
telephones?
d. If voluntary standards for interference immunity are developed,
should there be any blanketing requirements for telephones that do not
meet the voluntary standards for interference free telephones?

Licensee's Response Time

14. There is currently no criteria for speed of service for
correcting blanketing interference caused by new or modified station
operation. Based on case history, many stations have been slow to
respond, i.e., months before a complaint was acted upon, and often even
further delay before the interference was finally corrected. There is
also no specific requirement to maintain records of name, location,
type of complaint, etc. The public inspection file requirements,
however, do specify that license application engineering related
matters need not be retained longer than three years in the local
public inspection file. Accordingly, in that blanketing interference is
of engineering related circumstances, the Commission expects broadcast
licensees to maintain all letters of such complaints that are timely
filed with the station per the proposed Section 73.1630. However, in
order to establish a station's definitive efforts to solve blanketing
interference, should we require stations to maintain a specific log for
some period of time, such as two years after new construction or
transmitter modification which would include name, location, phone
number, date complaint filed, date complaint resolved, type of
complaint, list of affected equipment (manufacturer's name and model
number), and what action it took to resolve the complaint? And finally,
should we require licensees to respond to complaints within a specified
period such as 10 working days and to resolve the complaints within an
additional period of time such as 30 calendar days?

Conclusion

15. In light of the proliferation of electronic equipment available
to consumers, the increase in the number of broadcast stations, and our
concern about the effects of blanketing interference on future wireless
communication systems, we believe that it is time to revisit the
subject of broadcast blanketing interference. In addition to proposing
amendments to refine the Commission's rules and regulations in this
area for broadcast licensees, this proceeding may stimulate various
related industry manufacturers to begin to meet the challenge of
producing components that are less susceptible to blanketing
interference. We are proposing specific rule amendments in the
broadcast services that primarily clarify our current requirements.
Additionally, we seek specific comment on the questions raised,
especially those regarding telephone interference, and the specific
rule amendments proposed below.

Rule Changes

Part 73 of Title 47 of the Code of Federal Regulations is proposed
to be amended as follows:

PART 73--RADIO BROADCAST SERVICES

1. The authority citation for Part 73 continues to read as follows:

Authority: 47 U.S.C. 154, 303, 334.

Sec. 73.88 [Removed]

2. Sections 73.88 is removed.

Sec. 73.318 [Removed]

3. Section 73.318 is removed.
4. Section 73.685 is amended by revising paragraph (d) to read as
follows:

Sec. 73.685 Transmitter location and antenna system.

* * * * *
(d) (See Section 73.1630 concerning blanketing interference)
* * * * *
5. A new Section 73.1630 is added to Subpart H to read as follows:

Sec. 73.1630 Blanketing interference.

(a) Calculation of the Blanketing Interference Contour for AM
Stations. Areas adjacent to the transmitting antenna that receive a
signal with a strength of 1 V/m or greater will be assumed to be
blanketed. The determination of the location of the 1 V/m contour along
a radial shall be by actual field strength measurement or by iterative
vector summation of the field radiated by each antenna until the 1 V/m
contour is located. The distance from each tower to the point at which
the fields are being summed, shall be calculated using the Cosine Law
with the distance from the tower to the array reference point being one
side, the distance to the point of summation from the reference point
being the second side and the angle between the two sides being the
included angle. The field radiated by each tower is attenuated using
only inverse distance attenuation and the phase of the field component
from each tower shall be taken as the phase of the current at the
tower's current loop minus the space phase from the tower to the point
of summation.

Note to paragraph (a): If dn is the distance from the
reference point to the point of summation, sn the distance from
the reference point to the tower n, and n the
included angle, the distance Dn, from tower n, is given by
Dn = (dn2 + sn2
-2dnsncos( ))\1/2\. The Field ,
a vector quantity, is given by =
n/Dn where n is the field
radiated by tower n and Dn is the distance from tower n.

(b) Calculation of the Blanketing Interference Contour for FM and
TV Stations. Areas adjacent to the transmitting antenna that receive a
signal with a strength of 115 dBu (562 mV/m) or greater will be assumed
to be blanketed. In determining the blanketed area, the 115 dBu contour
is determined by calculating the inverse distance field using the
effective radiated power of the maximum radiated lobe of the antenna
without considering its vertical radiation pattern or height. For
directional antennas, the effective radiated power in the pertinent
bearing shall be used. The distance to the 115 dBu contour is
determined using the following equation:

D (in kilometers) = 0.394P
D (in miles) = 0.245P

Where P is the maximum effective radiated power (ERP), measured in
kilowatts, of the maximum radiated lobe.

(c) After January 1, 1997, permittees or licensees who either
commence program tests, replace their antennas, or request facilities
modifications and are issued a new construction permit must satisfy all
complaints of blanketing interference which are received by the station
during a one year period. The period begins with the commencement of
program test, or commencement of programming utilizing the new antenna.
Resolution of complaints shall be at no cost to the complainant. These
requirements specifically do not include interference complaints
resulting from malfunctioning or mistuned receivers, improperly
installed antenna systems, or the use of antenna booster amplifiers.
Mobile receivers and non-RF devices such as tape recorders or hi-fi
amplifiers (phonographs) are also excluded. (See the Appendix to
Sec. 73.1630 for covered devices and non-covered devices.)
(d) A permittee collocating with one or more existing stations and
beginning program tests on or after January 1, 1997, must assume full
financial responsibility for remedying new complaints of blanketing
interference for a period of one year. Two or more permittees that
concurrently collocate on or after January 1, 1997, shall assume shared
responsibility for remedying blanketing complaints within the
blanketing area unless an offending station can be readily determined
and then that station shall assume full financial responsibility.
(e) Following the one year period of full financial obligation to
satisfy blanketing complaints, licensees shall provide technical
information or assistance to complainants on remedies for blanketing
interference.
(f) A summary of the station's responsibilities are as follows:
(1) Complainant Within the Blanketing Contour.
(i) Complaint Received Within First Year of Operation--Paragraph
(c) of this section.
(A) DEVICES COVERED UNDER Section 73.1630--Licensee/permittee is
financially responsible for resolving interference complaints.
(B) DEVICES NOT COVERED UNDER Section 73.1630--Licensee/permittee
is not financially responsible for resolving interference complaints.
(ii) Complaint Received After First Year of Operation--Paragraph
(e) of this section.
(A) DEVICES COVERED UNDER Section 73.1630--Licensee/permittee is
not financially responsible for resolving interference complaints.
Licensee/permittee is required to provide technical assistance to
complainants. This entails the providing of information on the cause of
the interference and also providing information on proper corrective
measures.

[[Page 26496]]

(B) DEVICES NOT COVERED UNDER Section 73.1630--Same as paragraph
(f)(1)(i)(B) of this section.
(2) Complainant Outside the Blanketing Contour.
(i) Complaint Received Within First Year of Operation--Paragraph
(c) of this section.
(A) DEVICES COVERED UNDER Section 73.1630--Licensee/permittee is
not financially responsible for resolving interference complaints.
However, the licensee/permittee is expected to cooperate with
complainants by providing technical assistance in determining the cause
of the problem and providing advice on corrective measures.
(B) DEVICES NOT COVERED UNDER Section 73.1630--Same as paragraph
(f)(1)(i)(B) of this section.
(ii) Complaint Received After First Year of Operation--Paragraph
(e) of this section.
(A) DEVICES COVERED UNDER Section 73.1630--Same as paragraph
(f)(1)(i)(B) of this section.
(B) DEVICES NOT COVERED UNDER Section 73.1630--Same as paragraph
(f)(1)(i)(B) of this section.
