Interference-limited contours are used in the tv_process program to determine the number of persons that would receive DTV service, consistent with OET No. 69, the methodology used by the Commission in creating the DTV Table of Allotments.

PART 1: EVALUATION OF SERVICE The Area Subject to Calculation Under the FCC's rules, computation of a TV station's service area or coverage using the Longley- Rice methodology is limited to the areas within certain specific geographic contours. For analog TV, computations are made inside the conventional Grade B contour defined in Section 73.683 of the FCC rules, 47 C.F.R. § 73.683, with the exception that the defining field for UHF channels is modified by subtracting a dipole factor equal to 20 log[615/(channel mid-frequency in MHz)].
