noise reduction in the K3 as opposed to your experiences with other
You are confusing two different concepts. I believe the K3 supports both.
In its terminology, noise blanking is used to elimenate broadband spikes
and basically uses a very broadband detector, early in the receiver, to
mute the signal later in the receiver, where it has suffered enough
group delay to allow the blanker to react. It needs to be done in the
analogue processing, at least when digitising at less than 10s of Ms/s
Noise reduction is intended for relatively narrow band, or continuous
sources. I believe it includes an automatic notch filter, but it may
also involve blanking audio sub-bands with little energy, etc. It's
done in the software defined part of the system.
