I first saw a similar problem earlier today when I turned on NR on SSB. To
remedy it I need to increase the NR setting to something like F(2-4)- (1-4).
example - F-1-3 exhibits this problem, but F-4-1 does not exhibit this
problem. I wonder if this is a function of the just released firmware?
I believe the K3 second receiver is required to hear both VFOs at the
same time, but is that variable amplitude between VFOs possible with
the K3?
Each receiver has its own AF Gain control, so you get the same effect.
