S Meter Lite 2.15
July 6 2011
S Meter Lite is a no-cost program that displays your receiver's S Meter signal strength in a window.
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.
S Meters are usually not accurately calibrated - both in the S Unit and dB portions of the scale. S Meter Lite has a second mode of operation where the typical meter scale is replaced with a dB-only scale that is centered around S9 (S9 equals 0 dB). In this mode, S Meter Lite can be calibrated to follow decibel changes accurately. This mode is entered by pressing the dB button. Here is a screen capture from that mode.
The typical S Meter scale has been replaced with a scale that ranges from -18 dB, through S9, to +12 dB. Since the data points have been set with the help of an RF generator, and a step attenuator, they are much more accurate than the usual S Meter markings. This example shows a local AM broadcast station transmission. The red lines separate the use of two different antennas. The signal strength difference appears to be about 17 dB.
S Meter Lite supports the following radios:
ICOM IC-756PRO (I, II, III) (not the 756 standard)
ICOM IC-706MKIIG (not the other two 706 family members)
