I think you are wrong that this is not related to AGC Threshold. However, if THR = 8 is not enough to raise the level of the threshold above the noise you probably won't see a difference. The noise will still modulate the AGC which makes the radio seem noisier, and weak signals will be reduced by the AGC to the same loudness as the noise.
There seems to be a growing body of evidence including the figures quoted by W4TV that the K3's AGC Threshold cannot be set high enough at least for some radios / some user situations. If others think it is fine, that may just be due to gain variations or people being blessed with living in quiet locations. If you cannot lift the AGC threshold above the noise then perhaps you can try reducing the noise below the threshold by turning the preamp off and using the attenuator. I don't think the RF Gain will help with this as I seem to recall reading that it is really an IF gain control. ----- Julian, G4ILO.
