>From an operational standpoint I suppose it is useful (i.e., the segments filling up when you turn down the gain) so that you can adjust it visually to the approx level of the background noise by reducing it until the flickering stops.
Probably everyone adjusts RF gain by ear though; I mean those who don't just turn RF gain to max and leave it there. 73, Drew AF2Z On Thu, 30 Aug 2012 13:39:39 -0700, you wrote: >The S-meter reading is normally derived from the AGC voltage, and the AGC >voltage controls the RF Gain.
