  • stations will meet the contour overlap restrictions of Section 73.215(a) and we are not persuaded to do so here. Calvary's citation to Section 73.313(e) of the Rules is unavailing because that Rule section deals with the use of supplemental showings in the context of coverage prediction - not interference calculations. Calvary's reliance on the terrain roughness factor curves in Section 73.699 Fig. 10(e) of the Commission's Rules is misplaced. Use of those curves was suspended shortly after they were adopted because they often yielded anomalous results. Similarly, we cannot find that the ``point-to-point'' propagation model discussed in the Streamlining Order - but not adopted by the Commission - is an appropriate means of estimating contour overlap pursuant to Section 73.215(a).

Id. at n.12 (citing Fifth Report and Order, 17 FCC Rcd at 6704 � 39). This is necessary because a station's predicted 38 dBu signal contour is a function of its ERP, see 47 C.F.R. � 73.699 Figs. 10-10c, but the power limit for site-based AMTS stations in the rules and on their licenses is based on transmitter output power rather than ERP, see 47 C.F.R. � 80.215(h)(5), and determining a station's ERP requires additional information, such as antenna gain and line loss.

It observes that using the appropriate curves from Section 73.699 of the rules, the DTV power necessary to reach the Grade B contour was then determined radially. It states that when the maximum calculated power was found to be above the maximum power allowed (e.g., 1000 kW), the power was scaled to that maximum. H&E argues, however, that the scaling process necessarily reduces the directional replication pattern to power levels

Calvary's citation to Section 73.313(e) of the Rules is unavailing because that Rule section deals with the use of supplemental showings in the context of coverage prediction - not interference calculations. Calvary's reliance on the terrain roughness factor curves in Section 73.699 Fig. 10(e) of the Commission's Rules is misplaced. Use of those curves was suspended shortly after they were adopted because they often yielded anomalous results. Similarly, we cannot find that the ``point-to-point'' propagation model discussed in the Streamlining Order - but not adopted by the Commission - is an appropriate means of estimating contour overlap pursuant to Section 73.215(a).
