S Meter Lite is a no-cost program that displays your receiver's S Meter signal strength in a window. The next picture is an S Meter Lite screen capture. The S Meter data was obtained from my ICOM IC-756PRO radio. The large black bar below the typical S Meter scale is the S Meter reading, in this example, slightly more than S7 and a half. This bar is updated 20 times per second, and follows the S Meter on the radio. This window is shown at its actual size. The green bar above the S Meter scale displays additional S Meter data. It shows the minimum, maximum, and average S Meter values computed over a small period of time. In this example, it is the last one-half second. The left edge of the green bar is the minimum, and the right edge is the maximum reading. The black line within the green bar is the average S Meter reading computed from the last half second of accumulated data. The minimum S Meter reading is approximately S6.7, the maximum is S7.7, and the average is slightly more than S7.
