Lance, Both the AF Gain setting and the AGC on/off condition will modify the S-meter response. As a result, comparing S-meter readings with AGC on vs. off is not a valid comparison. All I can say is that "yes" the S-meter reading will change. Some combination of that behavior is present on each receiver I have ever owned or operated. Each one is different. How the S-meter changes with each condition depends on where the particular receiver picks off the S-meter signal.
