  § 90.175   Frequency coordinator requirements.

   Link to an amendment published at  83 FR 61095 , Nov. 27, 2018.

   Except for applications listed in paragraph (j) of this section, each
   application for a new frequency assignment, for a change in existing
   facilities as listed in § 90.135(a), or for operation at temporary
   locations in accordance with § 90.137 must include a showing of
   frequency coordination as set forth further.

   (a) Frequency coordinators may request, and applicants are required to
   provide, all appropriate technical information, system requirements,
   and justification for requested station parameters when such
   information is necessary to identify and recommend the most appropriate
   frequency. Additionally, applicants bear the burden of proceeding and
   the burden of proof in requesting the Commission to overturn a
   coordinator's recommendation.

   (b) For frequencies between 25 and 470 MHz: (1) A statement is required
   from the applicable frequency coordinator as specified in § § 90.20(c)(2)
   and 90.35(b) recommending the most appropriate frequency. In addition,
   for frequencies above 150 MHz, if the interference contour of a
   proposed station would overlap the service contour of a station on a
   frequency formerly shared prior to radio service consolidation by
   licensees in the Manufacturers Radio Service, the Forest Products Radio
   Service, the Power Radio Service, the Petroleum Radio Service, the
   Motor Carrier Radio Service, the Railroad Radio Service, the Telephone
   Maintenance Radio Service or the Automobile Emergency Radio Service,
   the written concurrence of the coordinator for the industry-specific
   service, or the written concurrence of the licensee itself, must be
   obtained. Requests for concurrence must be responded to within 20 days
   of receipt of the request. The written request for concurrence shall
   advise the receiving party of the maximum 20 day response period. The
   coordinator's recommendation may include comments on technical factors
   such as power, antenna height and gain, terrain and other factors which
   may serve to minimize potential interference. In addition:

   (2) On frequencies designated for coordination or concurrence by a
   specific frequency coordinator as specified in § § 90.20(c)(3) and
   90.35(b), the applicable frequency coordinator shall provide a written
   supporting statement in instances in which coordination or concurrence
   is denied. The supporting statement shall contain sufficient detail to
   permit discernment of the technical basis for the denial of
   concurrence. Concurrence may be denied only when a grant of the
   underlying application would have a demonstrable, material, adverse
   effect on safety.

   (3) In instances in which a frequency coordinator determines that an
   applicant's requested frequency or the most appropriate frequency is
   one designated for coordination or concurrence by a specific frequency
   coordinator as specified in § 90.20(c)(3) or § 90.35(b), that frequency
   coordinator may forward the application directly to the appropriate
   frequency coordinator. A frequency coordinator may only forward an
   application as specified above if consent is received from the
   applicant.

   (4) For any application for mobile repeater station operations on
   frequencies denoted by both § 90.20(d)(90) and (92), or by both
   § 90.35(c)(93) and (95) the frequency coordinator responsible for the
   application must determine and disclose to the applicant the call signs
   and the service areas of all active co-channel incumbent remote control
   and telemetry stations inside the applicant's proposed area of
   operation by adding a special condition to the application, except when
   the applicant has obtained written concurrence from an affected
   incumbent licensee, or when the applicant and the incumbent licensee
   are the same entity.

   (c) For frequencies above 800 MHz: When frequencies are shared by more
   than one service, concurrence must be obtained from the other
   applicable certified coordinators.

   (d) For frequencies in the 450-470 MHz band: When used for secondary
   fixed operations, frequencies shall be assigned and coordinated
   pursuant to § 90.261.

   (e) For frequencies between 470-512 MHz, 769-775/799-805 MHz,
   806-824/851-869 MHz and 896-901/935-940 MHz: A recommendation of the
   specific frequencies that are available for assignment in accordance
   with the loading standards and mileage separations applicable to the
   specific radio service, frequency pool, or category of user involved is
   required from an applicable frequency coordinator.

   (f) For frequencies in the 929-930 MHz band listed in paragraph (b) of
   § 90.494: A statement is required from the coordinator recommending the
   most appropriate frequency.

   (g) For frequencies between 1427-1432 MHz: A statement is required from
   the coordinator recommending the most appropriate frequency, operating
   power and area of operation in accordance with the requirements of
   § 90.259(b).

   (h) Any recommendation submitted in accordance with paragraphs (a),
   (c), (d), or (e) of this section is advisory in character and is not an
   assurance that the Commission will grant a license for operation on
   that frequency. Therefore, applicants are strongly advised not to
   purchase radio equipment operating on specific frequencies until a
   valid authorization has been obtained from the Commission.

   (i) Applications for facilities near the Canadian border north of line
   A or east of line C in Alaska may require coordination with the
   Canadian government. See § 1.928 of this chapter.

   (j) The following applications need not be accompanied by evidence of
   frequency coordination:

   (1) Applications for frequencies below 25 MHz.

   (2) Applications for a Federal Government frequency.

   (3) Applications for frequencies in the 72-76 MHz band except for

   ownership, control or corporate structure if there is no change in
   technical parameters.

   (10) Applications for mobile stations operating in the 470-512 MHz
   band, 799-805 MHz band, or above 800 MHz if the frequency pair is
   assigned to a single system on an exclusive basis in the proposed area
   of operation.

   (11) Applications for add-on base stations in multiple licensed systems
   operating in the 470-512 MHz, 769-775 MHz band, or above 800 MHz if the
   frequency pair is assigned to a single system on an exclusive basis.

   (12) Applications for control stations operating below 470 MHz,
   769-775/799-805 MHz, or above 800 MHz and meeting the requirements of
   § 90.119(b).
