  • the city of license, Otsego, Michigan, is 18.1 kilometers from the transmitter site chosen by Forum to serve Otsego. The predicted distance for a 70 dBu signal transmitted by a Class A FM station operating with maximum facilities, i.e., 6 kilowatts of effective radiated power and 100 meters of antenna height above average terrain (HAAT), is 16.2 kilometers. See Section 73.333 Figure 1 of the Rules. In this light, there is no reason to believe that Forum's Otsego transmitter site will provide a 70 dBu signal that will encompass Otsego, as required by Section 73.315(a) of the Commission's Rules. Therefore, we must deny Forum's Petition for Reconsideration of the staff action returning Forum's Petition for Rule Making. 4. Accordingly, IT IS

Therefore, petitioner's original petition for reconsideration and the subsequent "corrected" copy were both timely filed and will not be dismissed. The Commission's model predicts the field strength at distances from the transmitter according to the F(50,50) propagation curves in §73.333. These curves specify the estimated median field strengths expected to occur 50% of the time at 50% of the receive locations over a rolling or "average" terrain.

Here, Henderson fails to demonstrate that the terrain around the proposed site for Channel 274A at Caldwell departs widely (in excess of 50 meters Delta H) from the average terrain, other than stating that the Delta H of the path to the transmitter is 15. The F(50,50) curves in Section 73.333 of the Commission's Rules are based on terrain variations up to 50 meters Delta H. Henderson made no showing that it was appropriate to utilize a different propagation methodology. He did not show that the predicted distances to the 70 dBu contour were in question using the F(50,50) curves due to terrain around the proposed site departing widely from the
