This is pretty much my experience too [except the Africa part :-)]. I'm more or less CW-only and I just can't get NR to make any real improvement in the readability of signals. On the other hand, careful use of the DSP selectivity and passband position works great.
The IF Noise Blanker works super on electric fence and ignition noise [although ignition noise seems to be a thing of the past these days], and not-so-bad on power mains noise. Really aggressive settings start to create their own racket, but that's true for any IF blanker ... punch big enough holes in the signal often enough and you start to "hear the holes." The DSP NB is sort of in there with the NR for me and I rarely try it. 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org On 11/6/2012 12:30 PM, Arie Kleingeld PA3A wrote: > Hi Pete, > > The NR of the K3 is not a feature that shines.
