8. Clicking on the "Bands" control on the left changes the chart from "Time" to "Bands", and the circuit values for all bands are shown together. The right-hand controls select time-of-day, and the chart may be animated through all 24 hours. Changing the "Values" and "Modes" controls on the left change from Value hints to Mode hints on both the Bands and Time displays. When Modes is selected, chart hints show the Most Reliable Mode (MRM) of the propagation prediction. The mode hints identify the number of hops the ionospheric layer for the MRM. This chart is one of twelve in the Main Chart area. Other selections include Required Power Gain, Reliability, Elevation Angle, Signal Strength (in dB microvolts) and Signal Strength in S-units. Each parameter may be graphed vs. time-of-day or bands. Each chart includes an ID line at the top that duplicates the comment line of the Inputs panel. The ID line qualifies the chart for a particular circuit specification when the screen is printed for reference.
