Section 73.3571 - Processing of AM broadcast station applications(a) Applications for AM broadcast facilities are divided into three groups. (1) In the first group are applications for new stations or for major changes in the facilities of authorized stations. A major change for an AM station authorized under this part is any change in frequency, except frequency changes to non-expanded band first, second or third adjacent channels. A major change in ownership is a situation where the original party or parties to the application do not retain more than 50% ownership interest in the application as originally filed. A major change in community of license is one in which the applicant's daytime facilities at the proposed community are not mutually exclusive, as defined in § 73.37 , with the applicant's current daytime facilities, or any change in community of license of an AM station in the 1605-1705 kHz band. All other changes will be considered minor.(2) The second group consists of applications for licenses and all other changes in the facilities of authorized stations.(3) The third group consists of applications for operation in the 1605-1705 kHz band which are filed subsequent to FCC notification that allotments have been awarded to petitioners under the procedure specified in § 73.30 .(b)(1) The FCC may, after acceptance of an application for modification of facilities, advise the applicant that such application is considered to be one for a major change and therefore is subject to the provisions of §§ 73.3522 , 73.3580 and 1.1111 of this chapter pertaining to major changes. Such major modification applications will be dismissed as set forth in paragraph (h)(1)(i) of this section.(2) An amendment to an application which would effect a major change, as defined in paragraph (a)(1) of this section, will not be accepted except as provided for in paragraph (h)(1)(i) of this section.(c) An application for changes in the facilities of an existing station will continue to carry the same file number even though (pursuant to FCC approval) an assignment of license or transfer of control of said licensee or permittee has taken place if, upon consummation, the application is amended to reflect the new ownership.(d) If, upon examination, the FCC finds that the public interest, convenience and necessity will be served by the granting of an application, the same will be granted. If the FCC is unable to make such a finding and it appears that a hearing may be required, the procedure set forth in § 73.3593 will be followed.(e) Applications proposing to increase the power of an AM station are subject to the following requirements: (1) In order to be acceptable for filing, any application which does not involve a change in site must propose at least a 20% increase in the station's nominal power.(2) Applications involving a change in site are not subject to the requirements in paragraph (e)(1) of this section.(3) Applications for nighttime power increases for Class D stations are not subject to the requirements of this section and will be processed as minor changes.(4) The following special procedures will be followed in authorizing Class II-D daytime-only stations on 940 and 1550 kHz, and Class III daytime-only stations on the 41 regional channels listed in § 73.26(a) , to operate unlimited-time. (i) Each eligible daytime-only station in the foregoing categories will receive an Order to Show Cause why its license should not be modified to specify operation during nighttime hours with the facilities it is licensed to start using at local sunrise, using the power stated in the Order to Show Cause, that the Commission finds is the highest nighttime level-not exceeding 0.5 kW-at which the station could operate without causing prohibited interference to other domestic or foreign stations, or to co-channel or adjacent channel stations for which pending applications were filed before December 1, 1987.(ii) Stations accepting such modification shall be reclassified. Those authorized in such Show Cause Orders to operate during nighttime hours with a power of 0.25 kW or more, or with a power that, although less than 0.25 kW, is sufficient to enable them to attain RMS field strengths of 141 mV/m or more at 1 kilometer, shall be redesignated as Class II-B stations if they are assigned to 940 or 1550 kHz, and as unlimited-time Class III stations if they are assigned to regional channels.(iii) Stations accepting such modification that are authorized to operate during nighttime hours at powers less than 0.25 kW, and that cannot with such powers attain RMS field strengths of 141 mV/m or more at 1 kilometer, shall be redesignated as Class II-S stations if they are assigned to 940 or 1550 kHz, and as Class III-S stations if they are assigned to regional channels.(iv) Applications for new stations may be filed at any time on 940 and 1550 kHz and on the regional channels. Also, stations assigned to 940 or 1550 kHz, or to the regional channels, may at any time, regardless of their classifications, apply for power increases up to the maximum generally permitted. Such applications for new or changed facilities will be granted without taking into account interference caused to Class II-S or Class III-S stations, but will be required to show interference protection to other classes of stations, including stations that were previously classified as Class II-S or Class III-S, but were later reclassified as Class II-B or Class III unlimited-time stations as a result of subsequent facilities modifications that permitted power increases qualifying them to discontinue their "S" subclassification.(f) Applications for minor modifications for AM broadcast stations, as defined in paragraph (a)(2) of this section, may be filed at any time, unless restricted by the FCC, and will be processed on a "first come/first served" basis, with the first acceptable application cutting off the filing rights of subsequent, conflicting applicants. The FCC will periodically release a Public Notice listing those applications accepted for filing. Applications received on the same day will be treated as simultaneously filed and, if they are found to be mutually exclusive, must be resolved through settlement or technical amendment. Conflicting applications received after the filing of a first acceptable application will be grouped, according to filing date, behind the lead application in a queue. The priority rights of the lead applicant, against all other applicants, are determined by the date of filing, but the filing date for subsequent, conflicting applicants only reserves a place in the queue. The rights of an applicant in a queue ripen only upon a final determination that the lead applicant is unacceptable and if the queue member is reached and found acceptable. The queue will remain behind the lead applicant until a construction permit is finally granted, at which time the queue dissolves.(g) Applications for change of license to change hours of operation of a Class C AM broadcast station, to decrease hours of operation of any other class of station, or to change station location involving no change in transmitter site will be considered without reference to the processing line.(h)Processing new and major AM broadcast station applications.(1)(i) The FCC will specify by Public Notice, pursuant to § 73.5002 , a period for filing AM applications for a new station or for major modifications in the facilities of an authorized station. AM applications for new facilities or for major modifications, whether for commercial broadcast stations or noncommercial educational broadcast stations, as described in 47 U.S.C. 397(6) , will be accepted only during these specified periods. Applications submitted prior to the appropriate filing period or "window" opening date identified in the Public Notice will be returned as premature. Applications submitted after the specified deadline will be dismissed with prejudice as untimely.(ii)(A) Such AM applicants will be subject to the provisions of §§ 1.2105 of this chapter and 73.5002 regarding the submission of the short-form application, FCC Form 175, and all appropriate certifications, information and exhibits contained therein. Applications must include the following engineering data: (1) Community of license;(4) Hours of operations (day, night, critical hours);(5) Power (day, night, critical hours);(6) Antenna location (day, night, critical hours); and(7) All other antenna data.(B) Applications lacking data (including any form of placeholder, such as inapposite use of "0" or "not applicable" or an abbreviation thereof) in any of the categories listed in paragraph (h)(1)(ii)(A) of this section will be immediately dismissed as incomplete without an opportunity for amendment. The staff will review the remaining applications to determine whether they meet the following basic eligibility criteria:(1) Community of license coverage (day and night) as set forth in § 73.24(i) , and(2) Protection of co- and adjacent-channel station licenses, construction permits and prior-filed applications (day and night) as set forth in §§ 73.37 and 73.182 .(C) If the staff review shows that an application does not meet one or more of the basic eligibility criteria listed in paragraph (h)(1)(ii)(B) of this section, it will be deemed "technically ineligible for filing" and will be included on a Public Notice listing defective applications and setting a deadline for the submission of curative amendments. An application listed on that Public Notice may be amended only to the extent directly related to an identified deficiency in the application. The amendment may modify the proposed power, class (within the limits set forth in § 73.21 of the rules), antenna location or antenna data, but not the proposed community of license or frequency. Except as set forth in the preceding two sentences, amendments to short-form (FCC Form 175) applications will not be accepted at any time. Applications that remain technically ineligible after the close of this amendment period will be dismissed, and the staff will determine which remaining applications are mutually exclusive. The engineering proposals in eligible applications remaining after the close of the amendment period will be protected from subsequently filed applications. Determinations as to the acceptability or grantability of an applicant's proposal will not be made prior to an auction.(iii) AM applicants will be subject to the provisions of §§ 1.2105 and 73.5002 regarding the modification and dismissal of their short-form applications.(2) Subsequently, the FCC will release Public Notices:(i) Identifying the short-form applications received during the window filing period which are found to be mutually exclusive, including any applications for noncommercial educational broadcast stations, as described in 47 U.S.C. 397(6) , as well as the procedures the FCC will use to resolve the mutually exclusive applications;(ii) Establishing a date, time and place for an auction;(iii) Providing information regarding the methodology of competitive bidding to be used in the upcoming auction, bid submission and payment procedures, upfront payment procedures, upfront payment deadlines, minimum opening bid requirements and applicable reserve prices in accordance with the provisions of § 73.5002 ;(iv) Identifying applicants who have submitted timely upfront payments and, thus, are qualified to bid in the auction.(3) After the close of the filing window, the FCC will also release a Public Notice identifying any short-form applications received which are found to be non-mutually exclusive, including any applications for noncommercial educational broadcast stations, as described in 47 U.S.C. 397(6) . All non-mutually exclusive applicants will be required to submit an appropriate long form application within 30 days of the Public Notice and, for applicants for commercial broadcast stations, pursuant to the provisions of § 73.5005(d) . Non-mutually exclusive applications for commercial broadcast stations will be processed and the FCC will periodically release a Public Notice listing such non-mutually exclusive applications determined to be acceptable for filing and announcing a date by which petitions to deny must be filed in accordance with the provisions of §§ 73.5006 and 73.3584 . Non-mutually exclusive applications for noncommercial educational broadcast stations, as described in 47 U.S.C. 397(6) , will be processed and the FCC will periodically release a Public Notice listing such non-mutually exclusive applications determined to be acceptable for filing and announcing a date by which petitions to deny must be filed in accordance with the provisions of §§ 73.7004 and 73.3584 . If the applicant is duly qualified, and upon examination, the FCC finds that the public interest, convenience and necessity will be served by the granting of the non-mutually exclusive long form application, the same will be granted.(4)(i) The auction will be held pursuant to the procedures set forth in §§ 1.2101 et seq. and 73.5000 et seq. Subsequent to the auction, the FCC will release a Public Notice announcing the close of the auction and identifying the winning bidders. Winning bidders will be subject to the provisions of § 1.2107 of this chapter regarding down payments and will be required to submit the appropriate down payment within 10 business days of the Public Notice. Pursuant to § 1.2107 of this chapter and § 73.5005 , a winning bidder that meets its down payment obligations in a timely manner must, within 30 days of the release of the Public Notice announcing the close of the auction, submit the appropriate long-form application for each construction permit for which it was the winning bidder. Long-form applications filed by winning bidders shall include the exhibits identified in § 73.5005(a) .(ii) Winning bidders are required to pay the balance of their winning bids in a lump sum prior to the deadline established by the Commission pursuant to § 1.2109(a) . Long-form construction permit applications will be processed and the FCC will periodically release a Public Notice listing such applications that have been accepted for filing and announcing a date by which petitions to deny must be filed in accordance with the provisions of §§ 73.5006 and 73.3584 . Construction permits will be granted by the Commission only after full and timely payment of winning bids and any applicable late fees, and if the applicant is duly qualified, and upon examination, the FCC finds that the public interest, convenience and necessity will be served.(iii) All long-form applications will be cutoff as of the date of filing with the FCC and will be protected from subsequently filed long-form applications. Applications will be required to protect all previously filed commercial and noncommercial applications. Subject to the restrictions set forth in paragraph (k) of this section, winning bidders filing long-form applications may change the technical proposals specified in their previously submitted short-form applications, but such change may not constitute a major change. If the submitted long-form application would constitute a major change from the proposal submitted in the short-form application, the long-form application will be returned pursuant to paragraph (h)(1)(i) of this section.(i) In order to grant a major or minor change application made contingent upon the grant of another licensee's request for a facility modification, the Commission will not consider mutually exclusive applications by other parties that would not protect the currently authorized facilities of the contingent applicants. Such major change applications remain, however, subject to the provisions of §§ 73.3580 and 1.1111 . The Commission shall grant contingent requests for construction permits for station modifications only upon a finding that such action will promote the public interest, convenience and necessity.(j) Applications proposing to change the community of license of an AM station, except for an AM station in the 1605-1705 kHz band, are considered to be minor modifications under paragraphs (a)(2) and (f) of this section, and are subject to the following requirements: (1) The applicant must attach an exhibit to its application containing information demonstrating that the proposed community of license change constitutes a preferential arrangement of assignments under Section 307(b) of the Communications Act of 1934, as amended (47 U.S.C. 307(b) );(2) The daytime facilities specified by the applicant at the proposed community of license must be mutually exclusive, as defined in § 73.37 , with the applicant's current daytime facilities; and(3) The applicant must comply with the local public notice provisions of § 73.3580(c)(5) .(k)(1) An AM applicant receiving a dispositive Section 307(b) preference is required to construct and operate technical facilities substantially as proposed in its FCC Form 175. An AM applicant, licensee, or permittee receiving a dispositive Section 307(b) preference based on its proposed service to underserved populations (under Priority (1), Priority (2), and Priority (4)) or service totals (under Priority (4)) may modify its facilities so long as it continues to provide the same priority service to substantially the same number of persons who would have received service under the initial proposal, even if the population is not the same population that would have received such service under the initial proposal. For purposes of this provision, "substantially" means that any proposed modification must not result in a decrease of more than 20 percent of any population figure that was a material factor in obtaining the dispositive Section 307(b) preference.(2) An AM applicant, licensee, or permittee that has received a dispositive preference under Priority (3) will be prohibited from changing its community of license.(3) The restrictions set forth in paragraphs (k)(1) and (k)(2) of this section will be applied for a period of four years of on-air operations. This holding period does not apply to construction permits that are awarded on a non-comparative basis, such as those awarded to non-mutually exclusive applicants or through settlement. 63 FR 48625, Sept. 11, 1998, as amended at 64 FR 19501, Apr. 21, 1999; 67 FR 45374 , July 9, 2002; 68 FR 26227 , May 15, 2003; 71 FR 6228 , Feb. 7, 2006; 71 FR 76219 , Dec. 20, 2006; 75 FR 9806 , Mar. 4, 2010; 76 FR 18952 , Apr. 6, 2011; 85 FR 36794 , June 18, 2020 For purposes of paragraph (h)(1)(ii) of this section, §73.182(k) interference standards apply when determining nighttime mutual exclusivity between applications to provide AM service that are filed in the same window. Two applications would be deemed to be mutually exclusive if either application would be subject to dismissal because it would enter into, i.e., raise, the twenty-five percent exclusion RSS nighttime limit of the other.
