§ 74.24 Short-term operation.
All classes of broadcast auxiliary stations provided for in subparts D,
E, F and H of this part, except wireless video assist devices, may be
operated on a short-term basis under the authority conveyed by a part
73 license or a broadcast auxiliary license without prior authorization
from the FCC, subject to the following conditions:
(a) Licensees operating under this provision must be eligible to
operate the particular class of broadcast auxiliary station.
(b) The short-term broadcast auxiliary station shall be operated in
conformance with all normally applicable regulations to the extent they
are not superceded by specific provisions of this section.
(c) Short-term operation is on a secondary, non-interference basis to
regularly authorized stations and shall be discontinued immediately
upon notification that perceptible interference is being caused to the
operation of a regularly authorized station. Short-term station
operators shall, to the extent practicable, use only the effective
radiated power and antenna height necessary for satisfactory system
(d) Short-term operation under this section shall not exceed 720 hours
annually per frequency.
Note to paragraph (d): Certain frequencies shared with other services
which are normally available for permanent broadcast auxiliary station
assignment may not be available for short-term operation. Refer to any
note(s) which may be applicable to the use of a specific frequency
prior to initiating operation.
(e) The antenna height of a station operated pursuant to this section
shall not increase the height of any man-made antenna supporting
structure, or increase by more than 6.1 meters (20 feet) the height of
any other type of man-made structure or natural formation. However, the
facilities of an authorized broadcast auxiliary station belonging to
another licensee may be operated in accordance with the terms of its
(f) Stations operated pursuant to this section shall be identified by
the transmission of the call sign of the associated part 73 broadcast
station or broadcast auxiliary station, or, in the case of stations
operated by broadcast network and cable network entities, by the
network or cable entity's name and base of operations city.
(g) Prior to operating pursuant to the provisions of this section,
licensees shall, for the intended location or area-of-operation, notify
the appropriate frequency coordination committee or any licensee(s)
assigned the use of the proposed operating frequency, concerning the
particulars of the intended operation and shall provide the name and
telephone number of a person who may be contacted in the event of
interference. Except as provided herein, this notification provision
shall not apply where an unanticipated need for immediate short-term
mobile station operation would render compliance with the provisions of
this paragraph impractical.
(1) A CARS licensee shall always be given advance notification prior to
the commencement of short-term operation on or adjacent to an assigned
(2) The Commission may designate a frequency coordinator as the single
point of contact under this section for advance coordination of major
national and international events. Once designated, all short-term
auxiliary broadcast use under this section must be coordinated in
advance through the designated coordinator.
(i) Coordinators under this provision will not be designated unless the
Commission receives an initial request, in writing, to designate a
(ii) The Commission will issue a Public Notice with information
regarding the designation of such a coordinator.
(iii) All coordination must be done on a non-discriminatory basis.
(iv) All licensees must abide by the decision of the coordinator. The
Commission will be the final arbiter of any disputes.
(3) An unanticipated need will never be deemed to exist for a scheduled
event, such as a convention, sporting event, etc.
(h) Short-term operation is limited to areas south or west of the
United States-Canada border as follows:
(1) Use of broadcast auxiliary service frequencies below 470 MHz is
limited to areas of the United States south of Line A or west of Line C
unless the effective radiated power of the station is 5 watts or less.
See § 1.928(e) of this chapter for a definition of Line A and Line C.
(2) A broadcast auxiliary service station operating on frequencies
between 470 MHz and 1 GHz must be at least 56.3 kilometers (35 miles)
south (or west, as appropriate of the United States-Canada border if
the antenna looks within a 200Â° sector toward the border; or, the
station must be at least 8.1 kilometers (5 miles) south (or west, as
appropriate) if the antenna looks within a 160Â° sector away from the
border. However, operation is not permitted in either of these two
situations if the station would be within the coordination distance of
a receiving earth station in Canada which uses the same frequency band.
(The coordination distance is the distance, calculated for any station,
according to Appendix 28 of the International Radio Regulations.)
(3) A broadcast auxiliary service station operating on frequencies
above 1 GHz shall not be located within the coordination distance of a
receiving earth station in Canada which uses the same frequency band.
(The coordination distance is the distance, calculated for any station,
according to Appendix 28 of the international Radio Regulations.)
(i) Short-term operation of a remote pickup broadcast base station, a
remote pickup automatic relay station, an aural broadcast STL station,
an aural broadcast intercity relay station, a TV STL station, a TV
intercity relay station or a TV translator relay station in the
National Radio Quiet Zone, the Table Mountain Radio Receiving Zone, or
near FCC monitoring stations is subject to the same advance
notification procedures applicable to regular applications as provided
for in § 73.1030 of this chapter and § 74.12, except that inasmuch as
short-term operation does not involve an application process, the
provisions relating to agency objection procedures shall not apply. It
shall simply be necessary for the licensee to contact the potentially
affected agency and obtain advance approval for the proposed short-term
operation. Where protection to FCC monitoring stations is concerned,
approval for short-term operation may be given by the Regional Director
of a Commission field facility.
(j)(1) This paragraph applies only to operations which will transmit on
frequencies under 15 GHz. Prior to commencing short-term operation of a
remote pickup broadcast station, a remote pickup automatic relay
station, an aural broadcast STL station, an aural broadcast intercity
relay station, a TV STL station, a TV intercity relay station, a TV
translator relay station, a TV pickup station, or a TV microwave
booster station within the 4-mile (6.4 kilometer) radius Commonwealth
of Puerto Rico Protection Zone (centered on NAD-83 Geographical
Coordinates North Latitude 18Â°20â€²38.28â€³, West Longitude 66Â°45â€²09.42â€³),
an applicant must notify the Arecibo Observatory, located near Arecibo,
Puerto Rico. Operations within the Puerto Rico Coordination Zone (i.e.,
on the islands of Puerto Rico, Desecheo, Mona, Vieques, or Culebra),
but outside the Protection Zone, whether short term or long term, shall
provide notification to the Arecibo Observatory prior to commencing
operation. Notification should be directed to the following:
Interference Office, Arecibo Observatory, HC3 Box 53995, Arecibo,
Puerto Rico 00612, Tel. (809) 878-2612, Fax (809) 878-1861, E-mail
(2) Notification of short-term operations may be provided by telephone,
fax, or electronic mail. The notification for long-term operations
shall be written or electronic, and shall set forth the technical
parameters of the proposed station, including the geographical
coordinates of the antenna (NAD-83 datum), antenna height above ground,
ground elevation at the antenna, antenna directivity and gain, proposed
frequency and FCC Rule Part, type of emission, effective radiated
power, and whether the proposed use is itinerant. Applicants may wish
to consult interference guidelines, which will be provided by Cornell
University. In addition, the applicant shall indicate in its
application to the Commission the date notification was made to the
Observatory. Generally, submission of the information in the technical
portion of the FCC license application is adequate notification. After
receipt of such applications in non-emergency situations, the
Commission will allow the Arecibo Observatory a period of 20 days for
comments or objections in response to the notification indicated. The
applicant will be required to make reasonable efforts in order to
resolve or mitigate any potential interference problem with the Arecibo
Observatory and to file either an amendment to the application or a
modification application, as appropriate. If the Commission determines
that an applicant has satisfied its responsibility to make reasonable
efforts to protect the Observatory from interference, its application
may be granted. In emergency situations in which prior notification or
approval is not practicable, notification or approval must be
accomplished as soon as possible after operations begin.
