S Meter Lite

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. S Meters are often used as a basis for signal comparison. Perhaps the comparison is Between multiple stations or antennas. In order to make this comparison easier, it would be desirable to be able to save recent S Meter readings so that we could refer to them and see the difference. By clicking the Restore button on the above window, the window expands, revealing the full S Meter Lite window, shown in the following screen capture. The simple S Meter shown in the first picture has been augmented with several additional controls, and a large graph that shows the recent History of S Meter data. Again, the same green bar data interpretation is used. Each vertical green bar with a black dot represents the minimum, maximum, and average S Meter readings computed over a sample period - in this case, one half second. Since we are obtaining 20 S Meter samples per second from the radio, each sample or update period reflects the minimum, maximum, and average of 10 readings.
