(a) This section consists of the following Figures: 2, r3, 5, 6a, 7, 8, 9, 10, 11, 12, and 13. Additionally, formulas that are directly related to graphs are included.
(b) Formula 1 is used for calculation of 50% skywave field strength values.
Formula 1. Skywave field strength, 50% of the time (at SS 6):
The skywave field strength, F
c(50), for a characteristic field strength of 100 mV/m at 1 km is given by:
The slant distance, D, is given by:
Note (1): If |FM| is greater than 60 degrees, equation (1) is evaluated for | FM| = 60 degrees.
Note (2): North and east are considered positive; south and west negative.
Note (3): In equation (7), k = −1 for west to east paths (i.e., b
T), otherwise k = 1.
(c) Formula 2 is used for calculation of 10% skywave field strength values.
Formula 2. Skywave field strength, 10% of the time (at SS 6):
The skywave field strength, F
c(10), is given by:
(d) Figure 6a depicts angles of departure versus transmission range. These angles may also be computed using the following formulas:
Computations using these formulas should not be carried beyond 0.1 degree.
(e) In the event of disagreement between computed values using the formulas shown above and values obtained directly from the figures, the computed values will control.

Title 47 published on 2015-10-01
The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 47 CFR Part 73 after this date.
In this document, the Commission announces that, the Office of Management and Budget (OMB) approved, on an emergency basis, for a period for six months, an information collection for FCC Form 177, Application to Participate in a Reverse Incentive Auction, and certain Commission's rules contained in the Report and Order, Expanding the Economic and Innovation Opportunities of Spectrum Through Incentive Auctions, FCC 14-50. This document is consistent with the Report and Order, which stated that the Commission would publish a document in the Federal Register announcing OMB approval and the effective date of the rules and requirements.
In this document, the Media Bureau adopts the following a final catalog of expenses; a procedure whereby reimbursement payments will be disbursed via the agency's internal vendor payment system; a procedural requirement that the Reimbursement Form, with supporting cost documentation, must be submitted each time an entity makes a request for reimbursement from the Fund; and a decision that cost documentation, as well as the name, address, and other identifying information pertaining to vendors, will not be made publicly available.
This document resolves the remaining technical issues affecting the operation of new 600 MHz wireless licensees and broadcast television stations in areas where they operate on the same or adjacent channels in geographic proximity. Specifically, the Commission adopted the methodology and the regulatory framework for the protection of both wireless services and broadcasting in the post-auction environment that it proposed in October 2014. The Commission affirms its decision regarding the methodology to be used during the incentive auction to predict inter-service interference between broadcasting and wireless services. The Commission also affirmed its decision declining to adopt a cap on the aggregate amount of new interference a broadcast television station may receive from other television stations in the repacking process.
In this document, the Federal Communications Commission (Commission) proposes to extend its foreign ownership rules and procedures that apply to common carrier licensees to broadcast licensees, with certain modifications to tailor them to the broadcast context. The Commission also seeks comment on whether and how to revise the methodology a licensee should use to assess its compliance with the 25 percent foreign ownership benchmark in section 310(b)(4) of the Communications Act of 1934, as amended, in order to reduce regulatory burdens on applicants and licensees. Finally, the Commission makes several proposals to clarify and update existing foreign ownership policies and procedures for broadcast, common carrier and aeronautical licensees.
In this document, the Commission refines the rules it adopted in the Incentive Auction Report and Order and the preceding Channel Sharing Report and Order to provide greater flexibility and certainty regarding channel sharing agreements (“CSAs”). Among other things, we modify our rules to allow broadcasters that relinquish rights in the incentive auction in order to channel share to enter into CSAs after the auction and, whether they enter into CSAs before or after the auction, to determine the length of their agreements.
In this Second Order on Reconsideration, the Federal Communications Commission (Commission) provides more flexibility to broadcasters interested in the channel sharing option in the broadcast incentive auction by clarifying that back-up channel sharing agreements (“CSAs”) are permitted under its rules and providing more time for successful bidders to transition to shared facilities after the auction. The Commission also provides guidance regarding how the CSA exception to the prohibited communications rule applies with respect to back-up CSAs.
This document announces the final application procedures for the broadcast television spectrum incentive auction (Auction 1000), including the forward and reverse auctions (Auctions 1001 and 1002 respectively). This document also summarizes detailed information, instructions, and deadlines for filing applications, as well as certain post-auction procedures established by the Commission's prior orders.
In this document, the Federal Communications Commission (“Commission”) amends the portion of its rules known as the “Contest Rule” to permit broadcast licensees to comply with their obligation to disclose material contest terms either by broadcasting those terms or by making them available in writing on a publicly accessible Internet Web site. In particular, the Commission amends the Contest Rule to allow licensees to satisfy their disclosure obligation by posting material contest terms on the station's Web site, the licensee's Web site, or, if neither the individual station nor the licensee has its own Web site, any Internet Web site that is readily accessible to the public. The Commission also adopts requirements that define the disclosure obligation in cases where a licensee has chosen to meet its obligation through an Internet Web site.
Petitions for Reconsideration (Petitions) have been filed in the Commission's Rulemaking Proceeding by Ari Q. Fitzgerald, on behalf of GE Healthcare; Ronald J. Bruno on behalf of The VideoHouse, Inc.; Benjamin Perez on behalf of Abacus Television; Lawrence Rogow on behalf of WMTM, LLC; and Larry E. Morton on behalf of KMYA, LLC.
