Can anyone explain the interaction between the NR and setting the Threshold of the AGC? The manual states that, "When DSP NR is selected, digital AGC artificially reduces the threshold setting of the digital AGC--" Is it reduced to the default 3.03uv? I know that if I have the NR active, adjusting the Threshold control seems to have no effect. I like the NR for two reasons--sure helps with the urban QRN it seems and when I disable the NR, my sweep function freezes. (I did a master reset last week and then the Sweep seemed to work with the NR on or off, but it now has returned to it's old behavior. It will not work if NR is on. )

tnx, Gary
