Hi Robin The last firmware NR was a bit on the to aggressive side making everything sound like it was coming through a pipe or hollow sounding I found my self not using it often to fatiguing over time to listen to. This revised NR is a bit on the other side of the spectrum while the finish product is not hollow sounding it does not offer a lot of reduction.
Could be the code writers are "range finding" shooting long then short to zero in nirvana as a cw first operator who is not afraid to go very narrow on the filters I do not find myself using the NR a lot the suttle influence is closer to my liking then the to agressive aproach. So might it be nice to have both in the next release the 1-4 2-4 could be like but with a bit of tweaking for more Reduction of Noise but not to much and then the 3-4 4-4 come back in from the other side of to much NR where it was hollow through a pipe response Robin Diane Goldstein wrote: > hi all... elecraft/k3 newbie here (new owner of gently-cared-for > #2102)... have read everything i can find, but can't dig up an > answer, so this is my first post to the list: > > i've downloaded the latest beta firmware and have read all the posts > reciting joy and jubilation (my words) in connection with the > operation of the Noise Filter... but i think i'm missing something... > i work almost exclusively SSB and find that i'm listening to stations > buried in the QRN... i -thought- this was where the Noise Filter was > suppose to help, but when i turn on the NF and adjust it from 1-1 to > 4-4 i seem to hear a somewhat filtered/somewhat distorted version of > the input signal. i understand that the filter works automagically, > but as i go from X-1 to X-4 it sounds like some kind of notch filter > is being applied in increasing amounts, but not in a > meaningful/useful way... then it goes from X-4 to Y-1 and the > narrowing 'hiss' starts all over again, this time with a slightly > harmonic distortion. > > on very strong signals i can sometimes find a setting (usually 3-2 or > 3-3) that sharpens up the audio just a bit, but those signals usually > are loud enough to blast through the noise anyway... what i'm looking > for is help with the S2-S3 stuff. > > any advice or perhaps a pointer to an audio/video file showing the > filter in (proper) operation? > > btw, the NB seems to work just fine as does the notch filter. > > many thanks and 73! > robin (K9RDG) > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
