Compute the + 17 dBu contour as follows:
(a) Determine the effective antenna height above mean sea level according to the procedures in §§ 80.757–80.761.
(b) Determine the effective radiated power according to § 80,765. Determine
(c) Plot on a suitable map each point of + 17 dBu field strength for all radials and draw the contour by connecting the adjacent points by a smooth curve.
