  • this instance, KBAK-TV has not provided such information. Second, with regard to Grade B coverage, we note that the engineering information KBAK-TV has provided is based on the TIREM propagation method. In determining a station's technical coverage in relation to local coverage in market modification cases, the Commission has typically relied on propagation studies using standard methodology established in Section 73.684 of the Commission's rules. More recently, the Commission has accepted the use of Longley-Rice propagation studies which take geographic terrain into consideration in the determination of Grade B coverage. However, the Commission has not addressed or accepted the probity of the TIREM propagation method in any market modification case to determine technical service nor has it endorsed it as a

NBC also claims that over 99% of the total loss area within KNTV(TV)'s current Grade B contour would continue to receive Grade B or better service from at least five other analog stations. In its informal objection, Young asserts that NBC's engineering analysis is flawed because it fails to include a description of the methodology used, as required by Section73.684(f) of the rules, 47 C.F.R. � 73.684(f), or to justify the use of an alternative methodology. Thus, Young contends that it is impossible to verify NBC's loss and gain figures. Young further states that, rather than result in a net gain of 77,000 people, as NBC claims, the proposed analog modification will result in a net loss of service to

This determination was made using information in the engineering database, including directional antenna data, and using terrain elevation data at points separated by 3 arc-seconds of longitude and latitude, in conjunction with the FCC F(50,90) curves. The FCC curves (47 C.F.R. �73.699) were applied in the usual way, as described in 47 C.F.R. �73.684, to find this noise-limited contour distance, with the exception that dipole factor considerations were applied to the field strength contour specified in 47 CFR �73.683 for UHF channels. The station's post-transition DTV ERP was then calculated by a further application of FCC curves, with noise-limited DTV coverage defined as the presence of field strengths of 28 dBu, 36 dBu, and

  • We affirm our decisions regarding the protection contours for TV stations. First, we decline to change the method that must be used to calculate TV station protected contours. No party has described an alternative model that will provide more accurate calculations of TV station contours than the Commission's current method. The current method of calculating TV station contours in Section 73.684 of the rules using the FCC curves in Section 73.699 of the rules is straight forward, well understood and has proven sufficiently accurate over time. Given the lack of compelling information to the contrary, we believe that calculations of channel availability relying on that methodology will provide satisfactory protection of TV services. Further, with respect to Adaptrum's request that TV

A Grade B contour describes the area in which 50 percent of television sets will receive a viewable signal through an antenna 50 percent of the time. See 47 C.F.R. 73.684 (1997). The end result was essentially to require carriage in portions of petitioners' Grade B contours, taking into consideration individual facts involving each station, such as geographical and political boundaries and the nature, scope, and longevity of programming. Motions for reconsideration from the broadcast stations and the cable companies were filed and consolidated. The FCC adopted an order on August
