SWR PLOT allows you to enter up to 10 frequencies and their corresponding forward and reverse power readings. The program will then calculate and plot the SWR for each frequency on a bar graph. The program will plot on one of two graphs according to the highest SWR calculated. If the highest SWR calculated is over 2.5 to 1, the plot will be on a graph which reads up to 4 to 1. If any calculation is over 4 to 1 the plot line will extend to the 4 to 1 line and then print a plus (+) to indicate that the SWR is over 4 to 1. If the highest SWR calculated is 2.5 to 1 or less then the plot will be on a graph which reads up to 2.5 to 1. Using two graphs allows lower SUR calculations to be displayed on a larger scale. A 1 to 1 SWR is indicated by an asterisk (*) printed on the 1.0 to 1 line.
