- 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.

That value was rounded from the 15.19 value set forth in the FCC Advisory Committee on Advanced Television Service's (ACATS) Final Technical Report (October 31, 1995) at Table 5.1. *** The time variability factor is defined as the difference between the F(50,10) minus F(50,50), where these two values are determined from the charts in Section 73.699 of the Commission's rules, 47 C.F.R. 73.699. This factor is a function of the distance between the transmitting and receiving antennas. Using the factors in the above chart, the minimum signal level that needs to be present at the input terminal of a television receiver, to provide service is the sum of the thermal noise, the receiver noise figure,

- to provide assurance that TV services will be adequately protected. Given that the power of fixed TVBDs will be limited to 4 watts EIRP, the most important variable in determining the separation distance between a particular TVBD and a TV station's protected contour is the height of the device's antenna above ground. For example, using the FCC curves in Section 73.699 of the rules and the D/U protection ratios specified above, we find that a transmit antenna at a height of 30 meters transmitting with 4 watts EIRP could cause co-channel interference to a TV receiver with an antenna 10 meters above ground at a distance of 14.4 kilometers and adjacent channel interference at 0.74 kilometers. For transmitting antennas at lesser

- variations of field strength with time and location are incorporated into the television planning models. For analog TV, the SHVIA ILLR model defines service using the F(50,50) field strength curves. We note that DTV service differs in that it is based on use of F(50,90) field strength curves, as derived from the F(50,50) and F(50,10) field strength curves in Section 73.699 of our rules, to define a DTV station's noise-limited contour. The F(50,90) service contour means at least 50% of the locations can be expected to receive a signal that exceeds the field strength value at least 90% of the time. We also note that the field strength standard for analog reception (the Grade B contour value) incorporates an adjustment to

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.

- used a procedure that first derived the Grade B contour for an existing NTSC station, and then redefined that contour as the limit of protected service for the DTV facility (27.8 dBu for channels 2-6, 35.8 dBu for channels 7-13, and 40.8 dBu, with a dipole factor applied, for UHF channels). 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

- 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).
