[Elecraft] K3 NR triggering
Hi Steve I also seem to get the impression that the selected NR setting is not exacty the same as the selected level within in the menu versus turning the DSP NR on and off without entering the menu, if that makes sense. What I am finding is that 2-4 when applied from within the menu, does not sound like 2-4 when directly turning the NR on and off without entering the menu. It sounds different after you go and turn NR off and then on again. Maybe its just the latency in the DSP that I am noticing. Anyway new firmware, new learning curve, who knows? Anyone else notice this? I also seem to get the impression that the noise blanker is working much better, especially the DSP blanker, which is great. 73 Craig VK3HE __ 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] K3 NR in Ver 3.27
I have just installed 3.27 and the NR is a disaster. On turning it on there is virtually no AF output even at maximum AF gain setting. I have turned the K3 off and on but to no avail. Also there are big birdies on 40m (I haven't checked any other bands) which I am sure were not there before I upgraded from 3.25. Has anyone any ideas . If not it looks as if I will need to go back to 3.25.

First, I can hear the change of the filters now without turning things on and off, as you mentioned it would work. The frequency response is decidedly less flat (less bassy) than the sound of 3.25. For CW, the 3 and 4 settings are much more efficient, not so in SSB, where the 1 and 2 settings are much cleaner sounding and better copy. I found that with no antenna and with the RF gain turned to 12 o'clock... Turn on the NR and all receiver white noise mutes and slowly ramps up. That's a recursive effect, I guess. I prefer the sound of the 3.25 version for ssb, its cleaner and somewhat less bright (flatter in response). I had to tweak the RX EQ to add some bass in the 3.27 version or it sounds harsh in my headsets (I dont use speakers hardly ever, btw). Inteligibility is marginally better with 3.27 on ssb and quite a bit better on CW, so you have drifted a bit to the CW side of the equation, but with a decent compromise for SSB. No more boingy peakyness in any mode, which is good, and the level while it still drops a bit, is better behaved. Can I assume from some comments I have read here that the NR process is pre EQ and AGC? How exactly do the processes stack in the radio architecture? If NR is at the top of the stack, a decent fix might be to somehow gang these three processes using presets so that they can be set up ahead of time and recalled from a memory button by the user. As an old brodcaster, we used to preset things in Switchers (vision mixers to UK readers) using a process called E-MEM... Which could recall preset parameters in salvos to preset multiple settings. This might work here. This would be handy in a contest environment where a minimum of tweaking and rapid adaptation to changing conditions is needed... You could play outside of a contest and create the settings then in the heat of battle, recall them with a single button push from a canned setup. It wouldnt be perfect for any environment, but it might mean the difference between working a mult and not working a mult. And multipliers, after all, are :) As you said, every receiving environment is different, but some generalizations can be made and being able to recall the multiple settings would be a definite plus feature of the radio.

The NR is an adaptive filter. When you turn it off, it is completely reset: all buffers are flushed and filter coefficients zeroed. When you move from setting to setting with the NR adjust feature, the buffers are not flushed nor are the coefficients reset. Instead, the new settings are applied to the current state of the filter. So, it takes from a few tens of milliseconds to perhaps a couple of seconds for the filter to adapt to the new settings. 73, Lyle KK7P __ 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

Re: [Elecraft] K3 NR in Ver 3.27
I operate a lot on CW nets, with the b/w set to 700Hz, no EQ, AFX on, and use the NR to increase the apparent S/N ratio, and also to soften the effect of band noise on the ears. Before v3.25, this was frustrating because the NR took appreciable time to build the filter, and appeared to do so on each code element; the overall effect was to make the code sound mushy and harder to copy. Then v3.25 came along, and it made a big improvement. The mushiness was gone and by experimenting with the various settings, I could find a sweet point where the filters were not too aggressive and yet an appreciable improvement in copy was obtained. With v3.27, the filtering became even more focussed and this morning I used a 3-3 setting to pull weaker stations out of the noise on 40m, which was having one of it's less stellar days. I think the guys at Aptos are definitely going in the right direction, especially for the CW side of things. I've tried the NR on a couple of SSB nets, but there the improvement was less easy to pick out -- though I think it IS an improvement when you find the correct setting. Not a scientific review, just very subjective $.02 worth. 73, Van W1WCG __ 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
Re: [Elecraft] K3 NR triggering
Thinks likeIf F1-1 doesn't work, do we go to F1-2 or F2-1 or should we skip a few F's. Depends on the noise, the signal, the levels and the nature of the artifacts of NR you best tolerate. F1-x builds sharper filters, while F4-x typically has more attenuation... Should we turn NR off then back on every time we make a change? It usually won't adapt any faster if you do. Does changing NR settings while receiving a cw signal matter or should one change settings with no signal? Since you are trying to maximize the intelligibility of the signal, I'd only adjust it if there is a signal. I normally leave mine at F1-1 unless there is a good reason to change it. But that is for my antenna (3 element SteppIR), noise level (rural), band (20m daytime), mode (SSB), AGC settings (default THR and SLP) and typical signals (weak to moderate) I encounter here. 73, Lyle KK7P __ 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
Re: [Elecraft] K3 NR (what is the equiv to F3-1 from 3.25?)
hi... i'm one of the folks who is less happy with the 3.27 implementation of NR than the 3.25. i've been trying to do a 'scientific' comparison of the two, so i can record the audio and upload for others to hear/analyze (non trivial since band conditions and QSO's don't seem to last between loading of the FW) in any event, i'm listening right now to an LSB QSO on 7.182.50. receive EQ is totally flat, noise level here is about an S5. using 3.25, if i set the NR to F3-1, the noise drops down by about 50-75% and the audio peaks up (sharper/more intelligable) about 25% i then load 3.27 but can't find any settings that are similar... even F1-1 gives me a distinct ringing/echo (echo is not quite right... its more like the old spring reverb's of my youth!)... i think that F1-3 should at least match the taps of 3.25, but can i completely replicate the filter response of 3.25's F3-1? btw, i know there's a fair bit of multi-variable confusion and well, it works fine here, which is to be expected in beta testing... but given that (even with the small sample of this thread) folks seem to 'clump' into the two camps of works great and say what? i'm wondering if there's something else at play here? another bit of code that's specific to production run variation, or a change in the underlying DSP circuitry/programming during the life of the K3? lyle, is there, perhaps, a chart/form you could suggest for testing with some instructions (ie, make receive bandwidth flat, for SSB 40m, adjust bw/passband/etc., serial no of K3, etc?)... then those of us interested in more rigorous testing can provide some kind of unified feedback? i'm a beta tester for some other hw/sw consumer products and the reporting requirements usually establish a baseline so the engineers can look for patterns.

[Elecraft] One last rehash on tuning hash
In answer to Joe Planisky, here's my rehash on hash. My K3 which is factory built still has some tuning hash but it's now at a much lower in level, doesn't move the s-meter (with or without preamp) and is only centered around 28000 +/- 5 KHz. I can barely hear it now. I haven't added the h/w mod. Because this K3 is factory built and never been opened, lets assume it is properly built with cables and fasteners properly positioned and seated. Eric's comment: The h/w mod does not really impact the noise at all. It is required though and is there to maintain reliable signaling between the main processor and the synthesizers when the CPU to Synct serial bus speed is increased with SPI=2. Its the change to SPI=2 that reduces the noise. I've read some conflicting comments on the need to make the h/w mod. I gather it's Eric's position that it's necessary to keep the signals clean between the main MCU and synthesiszers. Before seeing this latest comment I was left thinking the h/w mod would also further reduce the tuning hash. With all this in mind I can live with small amount of remaining tuning hash. And, this K3 has been running in this configuration for almost a month without any signs of problems that could relate to omitting the h/w part of change. Cheers to the Elecraft team.

Re: [Elecraft] One last rehash on tuning hash
What Eric says is quite correct. Some of the confusion a few days ago was around the fact that I had completely different issue surface right after installing the hardware mod that suggested it was necessary to upgrade the firmware if the hardware mod is done. That's not true. The hardware mod simply equips the K3 to handle a faster bus rate that can be selected in the MENU with 3.24 or later firmware. The mod does not interfere with using the original bus rate. The faster bus rate reduces the tuning noise on the K3s tested. Normally, you'll need to remove the antenna or listen on a *very* quiet 6, 10, or 60 meter band to hear the VFO tuning noise. Don't forget there are other potential sources for noise, birdies, etc. Among them are loose/missing case screws (but don't over-tighten them - it doesn't help to make them tighter once they are firmly seated) and cables for the KRX3 subreceiver module not routed per the instructions. The KRX3 manual has details about the cable routing that must be observed for best results. It's worth checking these things if there are any sort of noises or birdies, especially if they seem to have gotten worse or suddenly appeared after working on your K3. One case screw that's often overlooked is on the side of the K3 near the forward end of the handle. It makes sure that side is held securely against the front panel shield inside.

Re: [Elecraft] K3 NR
I loaded bata 3.27 yesterday have played with it on cw and ssb so far I like what I hear the NR is more to my liking adding the AFX is a nice touch to get the audio to pop out a bit. The bands are not the best here for me using a Hy Tower vertical as the only HF antenna I would say that 3.27 is an over all improvement so far as I see and hear it.

[Elecraft] NR in the latest K3 firmware released yesterday
I find this to be a great improvement on SSB for weaker ones buried in the noise. With NR turned on to the F1-1 setting I could pull out the weak JAs and VK/ZLs this morning on 40 SSB. It truly works well without to much of the hollow in the tunnel reception. Turning up the NR settings beyond the first doesn't seem to offer improvement. On CW the improvement isn't that great unless I open up the bandwidth to the F1 SSB filter. With FL2 turned on to about 300 Hz the weak signal improvement isn't as pronounced as on SSB. I guess the question is to know if narrow band CW signals can expect the same level of improvement using any DSP NR algorithm? Also, the CW mode auto tune tap on SPOT is slick. I'll keep that.

Re: [Elecraft] One last rehash on tuning hash
Hi John, This is not a personal position - Its official current Elecraft company policy. :-) To be totally clear, if you enable 'VCO MD, SPI 2 for the VFO noise reduction, you MUST ultimately make the corresponding h/w mod. Its OK to test without making the mod to see if 'SPI 2' helps your situation, but then you ultimately must do the h/w mod. Failure to do so, when using 'SPI 2', may cause your K3 frequency tuning to be unreliable at random times, depending upon a wide range of variables, including band, temperature, supply voltage, type and number of options installed etc. The display frequency will tune normally, but the actual Synthesizer frequency, may not always follow correctly. Of course, if the 'VCO MD, SPI' menu entry is left at the default of 'SPI 1', you do -not- need to make the h/w mod. (Note: regarding the confusion in this: Ron's original posting where he thought he had a problem turned out to be a red herring. Upon further investigation we found he had fast tuning turned -on- for his RIT control and was not aware of it. He was also seeing the actual freq display change on his K3, which was the result of bumping the RIT control in this mode with RIT=OFF. :-) 73, Eric WA6HHQ Elecraft John Lawrence wrote: In answer to Joe Planisky, here's my rehash on hash.

[Elecraft] K3 Shift
Hello All, I built S/N 1354 from a kit , with FW 3.25 , I have installed most of the mods. I operate digi modes some of the time and I need to set the shift to 1.25 instead of 1.50 to be centered in the IF strip. It's been this way ever since I built it. I'm not sure what I have setup wrong . All filters are 8 pole . With the new shift steps set to 10 hz the shift control knob needs to be set all the way to the left ( 1.28 ) to be centered. Also on 160 M when I rotate the RIT knob fast to change the frequency I have some kind of image, Not sure what this is ??

[Elecraft] K3 NR triggering
It's become obvious to me that the most of the full time CW ops on the reflector were very happy with the fast responding, instant changing, very aggressive filters on the Pre 3.25 NR. So long as you didn't choose a filter that was too aggressive for your needs, I never found that I cut out any CW tones. As matter of fact, I found that with the old NR I was able to actually Enhance CW tones. I DO NOT find this to be the case with either 3.25, or 3.27. Without an Audio peak filter on the K3, I much prefer what I had previously. As a late night, high QRM 30meter DXer I find that I enjoyed the ability to switch between filter groups and hear the results instantaneously. Unlike SSB where you can wait that extra second, on CW, every dit and dah counts. Instead of trying to find a single NR DSP that would satisfy both groups, which seems near impossible to do. Wouldn't it be best to implement some way to have the OLD NR on CW mode, and then perhaps something like 3.25 or 3.27 on SSB mode? This way the CW guys, like myself, can enjoy the serious filter ability of the old NR, and the SSB guys can enjoy the pipeless artifacts when using NR in SSB mode. Some times you can't satisfy all the people all the time with one road. But you can send them in different directions and try to help them both at the same time.

Re: [Elecraft] K3 Shift
Hi Ken. You can save two unique filter setups using the NORM knob. 1. First, hold NORM to clear any shift to give you a good starting point. 2. Now set desired WIDTH and SHIFT the FC to where you want it. 3. Now do a LONG HOLD of the NORM knob till you see SAVE. Rotate the knob while you have it pressed to the left to save your custome filter to setting 1. 4. Do the same process and rotate to the knob to the RIGHT to save setting 2. I do this for SSTV and PSK. Its a quick and easy way to recall a custome filter for digital modes. Also, If you use DXLabs (and I believe others can do this as well but its very easy in DXL) you can enter CAT commands by mode. So when I use WinWarbler and select PSK it automatically sets the shift and the BW, and power output to what I want. No need to go to the radio to make any changes. It just happens.

Post-3.25, I find I'm now using it more often than not. My preference would be for progress to continue in the 3.25/3.27 direction. Of course, ideally they'll come up with a way to let each operator use what works best for them. 73 -- Joe KB8AP On Aug 27, 2009, at 11:18 AM, The Smiths wrote: It's become obvious to me that the most of the full time CW ops on the reflector were very happy with the fast responding, instant changing, very aggressive filters on the Pre 3.25 NR.

Re: [Elecraft] K3 NR - Audio Artifact on Button Press F1-x (Beta 3.27)
ok... this is something that other folks can absolutely test (grin) i have audio feedback (button beeps) turned on in my K3 and i've been playing with the 3.25 and 3.27 beta's i just noticed that with 3.27 that when i either 'turn on' or 'turn off' (momentary press) or long-press the NR button and the filter is set to either F1-1, F1-2, F1-3 or F1-4, the button beep is not a clean beep sound (sine wave?) but a little 'dirty' like there are some overtone/harmonics mixed in... you can possibly hear this through the speak, if you have great hearing, but it is very obvious with headphones (i'm using the sony mdr-v6) if you set the filter to F2-x, or F3-x, then the beep is perfectly clean and sweet (like a stravinsky concerto!) extra wrinkle... i have NB off but had NOTCH set to auto... turning the notch filter off or to manual seems to 'change' this behaviour, but not in a predictable way... with the notch filter off the button beeps are clean (i think) but sometimes turning the notch back on makes the beeps dirty again, and sometimes not... wish i could be more clear. btw, i'm doing all this testing with the audio level down to zero, listening through phones to just the beeps (yah, sometimes that's safer than trying to call CQ) some kind of interaction in the DSP between the NR code and NOTCH code? wondering if anyone else can repeat this and, if so, are you having success with the new 3.27 NR modes in SSB? many thanks to anyone who can do this test! 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
Re: [Elecraft] K3 NR triggering
I would like to still see some kind of APF filter to peak up weak cw, I'm still always looking for more volume or gain against the noise floor. For me its hard to compare something from a couple of months ago to what I have now in firmware but for the impressions or notes taken back with other firmware set ups, with varying band conditions I really can't tell unless you had two radios side by side to compare in real time both on the same antenna at the same time with no a/b switching. Out of 4 cw attempts at my daily cw fix only one had enough level of volume s/n that was a comfortable arm chair copy, another fellow K3 owner at a camp ground in Mo. I would go for the dual firmware one for CW and the other for SSB also, 3.27 does well on SSB with the audio response, so far I like it a lot. Regards Art ka9zap Some times you can't satisfy all the people all the time with one road. Truer words were never spoken! I'm a full time CW operator (well, 99.9% CW, 0.1% digital modes.) I played with the pre-3.25 NR quite a bit and I was never able to find a setting that made a CW signal easier to copy, so I never actually used it in a QSO. Post-3.25, I find I'm now using it more often than not. My preference would be for progress to continue in the 3.25/3.27 direction. Of course, ideally they'll come up with a way to let each operator use what works best for them. 73 -- Joe KB8AP On Aug 27, 2009, at 11:18 AM, The Smiths wrote: It's become obvious to me that the most of the full time CW ops on the reflector were very happy with the fast responding, instant changing, very aggressive filters on the Pre 3.25 NR. So long as you didn't choose a filter that was too aggressive for your needs, I never found that I cut out any CW tones. As matter of fact, I found that with the old NR I was able to actually Enhance CW tones. I DO NOT find this to be the case with either 3.25, or 3.27. Without an Audio peak filter on the K3, I much prefer what I had previously. As a late night, high QRM 30meter DXer I find that I enjoyed the ability to switch between filter groups and hear the results instantaneously. Unlike SSB where you can wait that extra second, on CW, every dit and dah counts. Instead of trying to find a single NR DSP that would satisfy both groups, which seems near impossible to do. Wouldn't it be best to implement some way to have the OLD NR on CW mode, and then perhaps something like 3.25 or 3.27 on SSB mode? This way the CW guys, like myself, can enjoy the serious filter ability of the old NR, and the SSB guys can enjoy the pipeless artifacts when using NR in SSB mode. Some times you can't satisfy all the people all the time with one road. But you can send them in different directions and try to help them both at the same time.

[Elecraft] Installing New Mods in K3
I have just installed the K3 VFO Tuning Noise Reduction mod and the K3 Automatic Front-End Protection mod in my newest K3. The mods went in well, but on the NoiseTuning Reduction mod, I did find the two vias on the left (viewing the RF board from the bottom) full of solder. I cut the 470 ohm resistor and soldered it in the proper via. I then cut the 1N4148 and soldered the anode in the proper via. The loose ends of these components were then cut and soldered together. Regarding the Automatic Front-End mod, be careful not to use too much solder on the right end of R56. I did, and created a bridge to the adjacent via. I had to use my desoldering gun to remove the excess solder. Now for the good news. While making these mods, I noticed that the KRX3 Subout Connector mod will be easily accessable. It is located under the bottom front panel same as the above mods. R8 is located on the right central part of the exposed RF board. The SMD resistor should not be hard to replace. I presume Elecraft will make this resistor available. Maybe it will be included in the P3 kit.

Re: [Elecraft] K3 NR triggering
Joe and all, As I understand the changes, in the pre-3.27 NR situation, there were audio peaks in the response envelope - so it worked very well (similar to an APF) for some who used a CW pitch near the peaks, but there were others who used other sidetone pitches and they were not happy with the CW NR at all. The peaking in the response made SSB NR unusable for me, but now it enhances the signal while getting rid of the noise - Yes, I hear a bit of 'hollowness', but that is acceptable to me - at least I can hear and understand SSB signals down near the noise level. The key to finding the right NR settings is to adjust them while listening to a signal - if there is no signal, any of the NR settings can reduce the noise, but it may not be a setting that is suitable for the band conditions, antenna, noise type or signal strength. With 3.27 on 20 meters at my location, I use F1-x through F2-4 on SSB, but the F3-x and F4-x give me some signal attenuation - many CW operators have reported that F3-x and F4-x work well for them on CW. Experiment with it a bit, but do it while listening to the weakest signal that you wish to hear, and you should be able to find what will work best for you under those band and noise conditions. 73, Don W3FPR Joe Planisky wrote: Some times you can't satisfy all the people all the time with one road.

Re: [Elecraft] K2 Noise Blanker Problem
Eric, First do a test to see if your NB is working at all. Remove the antenna, turn on the Preamp, then tap on the case of Q21 with a screwdriver. The taps will create impulse noise in the receiver which should be blanked when NB1 or NB2 is turned on. Be careful to differentiate between the clicks from the impulse noise and the rush of 'antenna/band noise' that happens because the screwdriver shaft can act as an antenna. If you find the NB is responding to that test, but it still does not help with your noise source, you can try widening the gate time a bit - try adding an additional .001 uF capacitor in parallel with C11 (just soleder ti to the solder pads for a test - if that helps, you can either leave the parallel cpacitor in place or change C11 to .002 uF. Other values may help as well, so some experimentation may be of help. If the noise gate is widened too much you will begin to notice holes on the received signal. 73, Don W3FPR eric norris wrote: I built my K2 some months back with the KNB2 option.

[Elecraft] 3.27 NR Works fine here
Hi Guys, I have just upgraded to the latest Beta release, using the new NR algorithm. In my opinion, it is the best it has ever been ! My only qualifier...I only operate SSB mode. 73 Glenn VK4BG __ 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] K2 - Connecting the K2 to a RigBlaster Pro and computer
Evening All I think it's time for a bit more of the combined wisdom of the list before I proceed. The rig is a K2. It has all the internal modules except the ATU at this point. I have successfully used both HRD and K2 Remote to control the K2. The RigBlaster Pro is several years old. It was connected to an Icom - 706 until tonight, but only really used for PSK31 with Digipan. P1, the mic jumper block has been reconfigured to the K2. And an on air test was satisfactory. It's now time to configure P16 for Rig Ctl, CW, PTT, FSK, etc. I believe that diagram #9 on page 29 of my manual is the correct configuration. Then the 232 cables would be compter to RigBlaster 232-A, and RigBlaster 232-B to K2. Is this correct? And finally, what experience do others have in connecting and using the K2 with a RigBlaster? Any recommendations on other hookups that work best? Maybe some that aren't obvious?

[Elecraft] W2 Watt meter
Hi Everybody; It sure would be nice to take a peak at the W2 manual especially since it is listed as shipping sometime between 2009-08/30 and 09/07. 73's, Bob K7HBG __ 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
Re: [Elecraft] W2 Watt meter
We're working on it right now. I'll post a preliminary version as soon as we have it. 73, Eric --- k7hbg @dslextreme.com wrote: Hi Everybody; It sure would be nice to take a peak at the W2 manual especially since it is listed as shipping sometime between 2009-08/30 and 09/07. 73's, Bob K7HBG __ _..._ __ 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
Re: [Elecraft] 3.27 NR Works fine here
hi glenn... since i'm one of the SSB operating folks who is having problems with 3.27 NR (but not 3.25) i'm wondering if you might answer some questions: 1. can you tell me your rig serial no/when it was mfg 2. what setting(s) are you using under NR and do you have AGC Fast or AGC Slow? 3. without NR on, what's the background noise S-level, and how much above that (if any) is the audio signal you're trying to pull out 4. are you using the 2.7 or 2.8khz roofing filter 5. what settings do you have BW/SHIFT/Hi/Low set at 6. when you turn NR on, what do you hear? (instant clean audio or a slow build-up? any echo effects or other audible artifacts?) 7. are you listening through the internal speaker/external speaker/phones and if stereo, do you have AFX on (and what setting) 8. have you altered your factory AGC settings under CONFIG from the defaults and if so, what settings are you using? 9. are you using a flat RX eq curve, or have you made any changes? 10. there is no question 10. i'm being a pain in the ss i know, so many thanks in advance for any info you can provide (and anyone else who is liking/loving 3.27 for SSB if you could answer these questions, that'd be great too!) 73, Glenn! robin (K9RDG) Hi Guys, I have just upgraded to the latest Beta release, using the new NR algorithm.

[Elecraft] NR for Dummys
Where can I buy the book? Let's start with SSB on 3.27 (for me at this time). Will somebody send me the non-factory settings you have changed and what you have them set to that give you the what you see as the best setting (at any particular instant). I know this will change by conditions, antenna, location, etc. BUT, I would like somewhere to start AND have an idea which settings you change that help you in addition to the NR settings. Is this impossible?
