5. This example adds a second curve for 90% Reliability, and the area between the 50% and 90% curves is shaded. The 90% curve shows the areas likely to be covered during 27 days of a 30-day month and is typical of conservative commercial HF operation. Starting with Version 2, you can now select any reliability level for the second curve of this display, or may show a selected reliability level as a single curve. When showing the ACE maps one after the other, a movie-like display is produced. In fact, the program that displays the sequential coverage maps is called MOVIE. Any of the area coverage displays may be shown on a world map -- a recommended procedure for the higher-frequency bands, where far-field fading is often present--or may be shown on a "zoomed down" map like the one shown above. Any one of four world maps or 24 zoomed-down maps of various world areas may be selected. Any given display screen may be printed once the area coverage limitations are produced. Then, the point-to-point analysis charts may be used to see the details of transmissions to particular locations. Each display includes an "ID" line that summarizes specified circuit parameters.
