Sec.  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are not superceded by specific provisions of this section.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 
performance.
    (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

[[Page 429]]

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 
outstanding authorization.
    (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 frequency.
    (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 
coordinator.
    (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 Sec.  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 200[deg] 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 160[deg] 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 
Sec. Sec.  73.1030 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 District 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 18[deg]20[min]38.28[min], West Longitude 
66[deg]45[min]09.42[min]), 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, 
Post Office Box 995, Arecibo, Puerto Rico 00613, Tel. (809) 878-2612, 
Fax (809) 878-1861, E-mail prcz@naic.edu.
    (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.
