The inverse option estimates a distance at which a threshold signal level is reached. Optionally graphs the elevation profile between the points on a rectangular plot, does fading calculations and stepping of parameters. Two transmitters may be plotted simultaneously, with either separate or combined contours. Optionally a CD-ROM drive may be used to provide map features such as political boundaries, water boundaries and roads. The map may also be scaled to allow use as a map overlay when plotted on plotters with up to size E vellum or paper.
