I listened to Eric & Wayne proclamations , and did not hear either say
that the "subtractive " algorithms were going into the k4. sooner or
later.
I believe that that is what BHI uses ....

Evert,
As one who suffers from such noise, I too look forward to such improvements.
The K4 will have a “subtractive” noise reduction/noise blanking algorithm that
essentially subtracts noise form a signal being copied. During the recent Zoom
call, I was told it would be available in about 3 months.
I think you can find a demonstration of this on YouTube somewhere. It is very
impressive.

For many years dynamic range and other receiver performance figures (see
Sherwood) and digital “features” like NB, NR, APF, Notch etc got a lot of
attention (which was good).
The transition from hardware to software opened a new world of possibilities.
But ….
Today, most of us are battling near-field man made noise instead of receiver
overload.
Reality tells us that this noise is not going to reduce the next decade or so.
Receivers will outperform competitors if they enable noise reduction and
improve S/N ratio.
This will be a combi of hardware (antenna’s and receivers) and smart software
solutions (algorithms etc.)
Just wondering if during the K4 design this “chance” was considered and if so,
how this was implemented ?
