Thanks for the NR news Wayne. I love working 160m, and I expect the new NR will be a welcome new tool. Really eager to hear some examples of it at work. 73, Bob N6WG > On May 31, 2019 at 10:11 AM Wayne Burdick wrote: > > > We've recently started testing a new DSP NR (noise reduction) algorit

I would think that, at best, there would be no benefit over using a fixed filter, optimised for the mode, and at worst, they would completely break the mode. The ideal digital mode signal looks like noise! COFDM as used for ADSL, digital TV, digital radio, and 4G mobile phones gets quite clo

I'm fairly happy with my K3's NR/NB. I could always use more and better NR, or course, but a major negative for me is the long time it takes for the filter to rebuild when changing NR settings or WIDTH. I hope the K4 will be speedier... 73, Drew AF2Z On 05/31/19 13:11, Wayne Burdick wrote:

That sounds promising! A side-by-side comparison of the same noise samples on a K3 would be interesting as well. 73, Drew AF2Z On 05/31/19 13:11, Wayne Burdick wrote: We've recently started testing a new DSP NR (noise reduction) algorithm for the K4. Our early testers are saying it's as good

Hi Wayne, The K3S’ NR algorithm is not operable on digital modes. Will that be the case on the K4 as well? 73, John WA1EAZ > On May 31, 2019, at 1:11 PM, Wayne Burdick wrote: > > We've recently started testing a new DSP NR (noise reduction) algorithm for > the K4. Our early testers are say

We've recently started testing a new DSP NR (noise reduction) algorithm for the K4. Our early testers are saying it's as good or better than anything else they've used, removing stochastic noise without the characteristic "hollow" sound of earlier algorithms. In my own tests, I'm finding weak SS
