K4 NR & NB

[Drew AF2Z]

Has there been any news about the K4 NR & NB? If so, I've missed it. I'm
particularly interested in the user interface compared to the K3.

On the K3 the NB has 21 DSP settings and 21 IF settings which have to be
scrolled through sequentially to find the best ones. The NR has 32
settings to scroll through, with a noticeable delay to build each one
after selected. Also a delay to rebuild every time the width filter is
changed.

I expect the annoying delays will not be present on the K4 with the
faster processor, but what of the filter selection: will we still need
to scroll sequentially through long strings of NR & NB presets?

Despite the limitations of the K3 filters I have found them to be very
useful for my local noise problems. Still, I hope there is something
better on the K4...


73,

Hi Drew,

The K4 has one linear control range of 0-15 for both NR and NB, making
adjustment far simpler. There's virtually no delay in setting up NR.

Will the NR "mixed mode" (NRmF5-x and above) where some of the
unprocessed signal is mixed with the processed signal be available on
the K4 as it is on the K3?  I've discovered that feature coupled with
the APF is an excellent way of copying near-the-noise CW signals.

Thanks & 73,
Brian, K0DTJ
