[Lowfer] Sudden Fades?

[Dexter McIntyre W4DEX]

I have seen what you describe Bryce.  One way to see the noise floor changes with Argo is to run it with the AGC off.  It's seldom I can use Argo in that mode but it's nice to have the capability.

Since I see that AGC is usually on in these screen shots, isn't it more likely that the local noise floor has jumped?  Even if a couple signals disappear couldn't it be because the ones that stay are only there because they were strong enough to still be above the new noise floor?  Just curious about which is contributing more, an actual drop in Rx signal strength or a rise in the noise floor.
