K3's NR is more difficult to use but, with low settings like 1-1 or 5-1/5-2/5-3, I find it excellent and it compares favourably (equivalent) with the KX3 and other brands or rigs using mid-range settings. The more agressive settings are very special to use... I tested a lot of NR with various brands. Overall, none is better than the others but for some particular situation, one brand may give better results. This may explain this particular result with the static noises.

[Elecraft] K3 - noise reduction query
I find the noise reduction NR in KX3 is much easier to use and gives a better effect than NR in K3. I just wonder whether other elecrafters feel the same. Regrettably, none of the 4 x 8 =32 settings in the NR of K3 gives the performance in par with the NR in KX3. My observations only relate to SSB operation. I always try to find a way to effectively use the NR in K3 but failed. Perhaps, experts here could guide me to the right way to use the NR in K3. 73 Johnny VR2XMC 寄件人︰ Lyle Johnson 收件人︰ elecraft@mailman.qth.net 傳送日期︰ 2014年07月5日 (週六) 12:47 PM 主題︰ Re: [Elecraft] K3 - noise reduction query There is an incredible range of characteristics to unwanted "signals" that we loosely call noise.

OK; thanks for that; I stand corrected---to a large degree---turns out that their meanings actually overlap depending on the context in which each word is used (although I was brought up by a newspaper editor dad who explained things like this to me at an early age). While foundering at sea means filling with water and sinking floundering can mean almost the same thing; to flail about helplessly or be lost in a manner of speaking---as you so rightly point out.

Re: [Elecraft] K3 - noise reduction query
If you are talking about SSB on 80 and 40 - I was playing with trying to copy the K2M on 40 M SSB last nite thru all the qrn - something to play with is the SSB bandwidth and shifting the band- it makes a lot of difference depending on how the guy has his audio tailored or how his voice is. You also have a lot of AGC handles to play with - last night reducing slope and playing with threshold made significant differences at times. I don't think there is any magic bullet - conditions change and what works one time or at one location will be different another time. What works for one person . one location is very unlikely to be the solution at another place. I used TenTec Orions for about 10 years - they had an incredible NB for clean line noise spikes BUT BUT if there were any strong signals anywhere near (25 -50 khz or more) where you were listening , the blanker was useless -but absolutely great on a quiet band. I have never found a K3 line noise NB setting as good as the ORION BUT BUT I can get decent blanking in crowded band conditions -- I will take that any day over unusable incredible . Years ago Collins used to drive their blanker with a separate noise RX at about 40 mhz - often wished the Orion did that . NR is a whole different story - I have already been thru ten years of NR discussions, in my case for me NR F1-1 is as good as anything I have used on either CW or SSB but that is for me - a top flight contester friend across town with Orion and K3 to A/B and who lives in a 10 dB quieter location has entirely different opinions. What works for him is entirely different for me. NO MAGIC BULLET. My two cents worth . 73 Hank K7HP I am hoping someone out there has come up with a magic bullet setting (or even a workable setting) that can be shared.

Re: [Elecraft] K3 - noise reduction query
Probably K3 NB is not effective filtering your particular noise. Impulsive noise is very hard of characterize because are infinite patterns possible. I have filtered majority of arching noise but eventually not was possible. You are tested NB analog and NB digital and combined both? I remember a 11m radio (3-5825A) with a NB more effective than TS-440S, with only a particular noise. Recently I discovered a static noise effectively filtered by IC-736 but a IC-781 wasn't capable We must accepts not cheap equipment wasn't capable filter a type of noise is frustrating.

Re: [Elecraft] K3 - noise reduction query
The K3 is far more capable than the 480 and has the entire line running from it. I should not have to be content with the 480 - that is why I have the K-Line. That said, I am sure there is a setting out there that will work - I have not found it - hence, the reason I ask.

Re: [Elecraft] K3 - noise reduction query
Actually - all of the above. I have spent a lot of time playing with all the NB and NR settings (there are many combinations) and have incorporated the ATT and reduced RF Gain into the mix. My understanding is bringing in the RF at a lower level allows the various DSP devices to get a running start at cleaning up the noise. So far I have had very little success. I am hoping someone out there has come up with a magic bullet setting (or even a workable setting) that can be shared. This has been a summer with loads of lightning static.

Re: [Elecraft] K3 - noise reduction query
Hi Bill, Are you using; NR, IF NB, or dsp NB?

Re: [Elecraft] K3 - noise reduction query
Bill, I suggest you use your TS-480 rather than the K3 if that's what works for you.

Re: [Elecraft] K3 - noise reduction query
I am trolling for nothing other than suggestions and possibly successful settings used by other K3 users. The purpose of this reflector is to aid owners/users of Elecraft equipment. If you have a problem with my asking for K3 operating information and shared knowledge - TUFF!

Re: [Elecraft] K3 - noise reduction query
> The sad part is that My cheap little Kenwood TS480 does a much better > job of cleaning up this noise. You are trolling for complaints on the Elecraft noise reduction - not looking for a "solution". The Elecraft noise reduction is designed for "smooth" noise - not impulse noise which is a noise blanker function. A smooth noise reduction system (LMS) operates by forming bandpass filters around what it determines to be "signal" components and passing just the "signal". You will have better results with lightning by working with the noise blanker - probably on a "long" setting - as it is designed to work with fast rise time signals. 73, ...

[Elecraft] K3 - noise reduction query
It is lightning season and I have been floundering around the menus on the K3's DSP NR system. I have found no setting that really do much of clean-up on lightning static. I also have tried using the ATT and RF Gain settings also. The sad part is that My cheap little Kenwood TS480 does a much better job of cleaning up this noise. Of course, lightning static is very random and difficult to reduce. My use of HF is 40 and 75, so directional antennas are not an option - as some suggested.
