[Elecraft] The great P3
This morning I wanted test my P3 - I have mounted a10mhz inverted see antenna, that I use from some days. I have an HP8640A and a Racal 9914 ovenized counter. I tested the K3S+P3 with signals starting at -135dBm up to -73dBm (S9). I thought that the P3 is a great weapon for doing and contesting. Now, after seeing the absolute precision of the P3 at every signal level I can say that it is a real measurement instrument, a kind of real spectrum analyzer.

[Elecraft] A request to Wayne - K3S NR firmware mod.
To Wayne and his Elecraft crew: I am an ultra satisfied cw user of a Elecraft K3S ( that I use with P3 and two SP3). The only things that I dont like are: - the noise blanker - i havent found situations where it help - or I am unable to use it, even if I tried lot of settings… - the NOISE REDUCTOR, that first times I thought it help barely, but after some time I found that it simply need to be reset (simple OFF-ON) at band noise changing time after time and it work well. About the NB I dont ask anything ( I simply accept that it doesn’t work), but about NR - Noise Reductor I ask you that with next firmware modifications you introduce an automatic NR reset ( at least every 5 minutes a ciclic OFF-ON, it simply improve a lot its results) Many thanks. 73 es gl, Ian IK4EWX __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] A request to Wayne - K3S NR firmware mod.
Noise blankers are difficult to design and to use. They work by blanking out the receiver during noise pulses. The user defines what is a noise pulse and how aggressively to blank it by adjusting the NB parameters. If you don't blank out enough, you still hear the noise. If the signal is below that noise, you won't hear it. If you blank out too much, you lose so much real signal that it is no longer possible to copy or to copy comfortably. *I have had very good results with the NB in the K3 on some kinds of human-made noise.* Other noises seem to have too high a duty cycle or signal strength to be effectively blanked. Your noise sources may be in that category. I don't think it is fair to say the K3 NB "doesn't work." It certainly does work on many kinds of noise. No NB that I have tried or heard of can work on all kinds of noise. 73, /Rick N6XI Rick Tavan Truckee, CA On Sun, Sep 3, 2017 at 8:12 AM, Gian Luca Cazzola wrote: > To Wayne and his Elecraft crew: > > I am an ultra satisfied cw user of a Elecraft K3S ( that I use with P3 and > two SP3). > > The only things that I dont like are: > - the noise blanker - i havent found situations where it help - or I am > unable to use it, even if I tried lot of settings… > > - the NOISE REDUCTOR, that first times I thought it help barely, but after > some time I found that it simply need to be reset (simple OFF-ON) at band > noise changing time after time and it work well. > > About the NB I dont ask anything ( I simply accept that it doesn’t work), > > but about NR - Noise Reductor I ask you that with next firmware > modifications you introduce an automatic NR reset ( at least every 5 > minutes a ciclic OFF-ON, it simply improve a lot its results) > > Many thanks. > > 73 es gl, > Ian IK4EWX > __ > 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 > Message delivered to rta...@gmail.com __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] Noise Blankers
I have never found the K3 noise blanker to be effective. On the other hand, in side-by-side comparisons, the noise blanker in my old FT-1000D can be very effective on my ever present power line noise. However, like all noise blankers of that design, it only works if there are no strong signals within many kHz of the operating frequency, so it's completely useless on a crowded band. The only way around this I know of is to use a second receiver, tuned to a clear spot nearby, to control the noise blanker. BTW, the K3 noise blanker uses a filter with a bandwidth of about 100 kHz. The idea is that, in such a wide bandwidth, the amplitude of the noise pulses should be large, making them easier to distinguish from signals. (The FT-1000 uses something like 15 kHz.) However, I've never been able to get the K3 NB to work, even on a completely dead band. Under the same conditions, I can often get a 20 dB reduction with the other radio. That I don't understand. I should investigate that sometime. 73, Scott K9MA -- Scott Ellington --- via iPad > On Sep 3, 2017, at 10:37 AM, Rick Tavan wrote: > > Noise blankers are difficult to design and to use.

[Elecraft] Fwd: Noise Blankers
Forwarded Message Subject:[Elecraft] Noise Blankers Date: Sun, 3 Sep 2017 13:59:59 -0400 From: Ralph McClintock To: k...@sdellington.us Scott, There are two NBs available in the K3. Have you tried the K3 DSP NB? Don't even tell me about the "NB" in the FT-1000. Been there; _fought_ with Chip K7JA at Yaesu about how bad it was until he quit responding. That was about 1992/3. Tom W8JI finally explained where Yaesu really screwed the pooch with their entire FT-1000 line NB wise. I went through every rig from 1990 right up to 2014 when I got my 2nd K3 and the latest DPS software. During that time I was fighting electric fence and power line "crap" on 160 meters, my main band of interest. The "regular" for lack of a better word, Noise Blanker, in the K3 is probably okay for auto ignition noise, like all the rest, but for what I faced it was the DSP NB that blew all the rest of the crap away. NO Problems with strong signal overload on 160. I could copy very weak signals right in between New England/NY big guys, and that is on my transmit antenna! The K3 DSP NB was, and still is, a game changer for me. Give it a try on your power line junk.

Re: [Elecraft] Noise Blankers
I find the K3 NB to be surprisingly effective. I also find that adjustment is highly dependent on the characteristics of the signal and the noise, and the effects of changing those adjustments is subtle. The effect of a blanker on ignition noise was really astounding ... "was," because ignition noise seems to be history these days. I suspect that many of the "it doesn't work very well" observations may stem from anticipation of a dramatic disappearance of today's noise from incidental and unintended radiators with NB on. My local noise comes from the NV Energy power system and an uncountable number of Part 15 violators in the house and neighborhood. K3 NB is very effective for me against them. I am a bit sorry that both the IF and DSP blanker parameters are so cryptic in the K3. Depth of the blanking pulse and width of the blanking interval are the two "real" parameters involved. The K3 seems to camouflage them which, for me at least, makes them a bit harder to adjust properly, I'm not sure what I'm doing when I change them. Incidentally, punching holes in the receiver sensitivity to block noise pulses is itself introducing noise. As with everything else in life, it's a trade-off. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/3/2017 9:40 AM, Jim Brown wrote: On 9/3/2017 9:18 AM, K9MA wrote: I have never found the K3 noise blanker to be effective.

Re: [Elecraft] Noise Blankers
I agree. The adjustments are far too many and arcane. I'm currently plagued with powerline noise that has yet to be fixed, although they are supposed to be working on it.

Re: [Elecraft] Noise Blankers
In my experience, NR is much better than NB against power line noise. However, NR does not work on DATA mode. I use BHI Compact In-line DSP Noise Eliminating Module, which is inserted between K3 line out and USB audio module. For effectively eliminating noise, tuning RF gain and AGC level in addition to NB and/or NR would give you better results. de JH3SIF, Keith > 2017/09/04 4:38、Wes Stewart のメール： > > I agree.

Re: [Elecraft] Noise Blankers
Depending the type of noise, for repetitive pulse type noise only, the Noise Blanker does it job. Now one must understand that all pulse noise is not alike. Therefore, different values of NB, both with the IF values and with DSP values, will require some adjustments. If the noise is not repetitive then the NB is not the better choice but the NR is the better choice. Again, depending on they type of noise, certain combinations of NR values will be necessary. Yes, that is correct in that the Noise Reduction function is not available or can not be activated in the DATA mode. However the Noise Blanker can be used in the DATA mode. Again, the Noise Blanker is for repetitive pulse type noise. I've spoken with many hams and find their understanding of Noise Reduction being described as often does not work as expected. Further discussion seems to indicate they want NENoise Elimination. Well, NRNoise Reduction does in fact work when the values are selected based on the type of broad noise spectrum being encountered. NR has very little effect on pulse type noise. One fact not clearly understood, is that most hams operate with too much RF Gain. Thus the correct application of ATTENUATION and RF Gain reduction will greatly improve receiver performance in the face of noise. Optimizing receiver gain compared to band noise and the noise floor of the receiver is explained in a quote from Rob Sherwood, Sherwood Engineering: "If receiver noise floor is 10 dB below band noise, the receiver is contributing less than 0.5 dB of the total noise. Band noise varies by band over 30 dB, 160-10 meters. It also varies by direction and time of day, plus what the sun is doing. In an noisy urban environment it is anybody's guess as to your band noise level. A simple test is to see how much the noise coming out your speaker increases when you switch between a dummy load and your antenna, when tuned to a dead spot on the band. Example on 10 meters at my rural QTH, IC-756 Pro III: preamp OFF, noise goes up 3 dB. That means the receiver is contributing half the noise. Preamp 1 ON, band noise goes up 9.5 dB. Almost all legacy receivers are designed for 10 meters, and attenuation is desirable on the low HF bands." In Rob's first statement, how do we get the band noise to be 10 dB above receiver noise? Use Attenuation and RF Gain reduction. As an example, if receiver noise floor is -130 dBm and the band noise, no signal, is S-5 or -97 dBm, the difference being 33 dB. This would then indicate one should employ 15 dB of Attenuation and 8 dB of RF Gain reduction. Or 10 dB of Attenuation and some 13 dB of RF Gain reduction. Of course the band noise will be comprised of different noise components, depending on band and many other factors as he suggests. 73 Bob, K4TAX On 9/3/2017 3:06 PM, Keith Onishi wrote: In my experience, NR is much better than NB against power line noise.

Re: [Elecraft] Noise Blankers
Just a couple of points. In the K3(S) there is no "RF Gain" control unless by RF gain you mean "It's not the audio gain gain control." The "RF" gain control operates on the i-f amplifier, which is after the analog noise blanker. In this regard, it is little different from AGC, which operates on exactly the same circuitry. Why some people believe that they are better at controlling i-f gain than the AGC system does is beyond me, but old wife's tales die hard. If this is hard to fathom, watch the S meter as you reduce "RF" gain. The reading increases, no different from letting the AGC do it. Attenuation is a different matter. It operates at RF and is a viable tool. About noise blanking, I think I had a little to say about that almost 40 years ago: http://k6mhe.com/n7ws/Noise_Blanker.pdf Wes N7WS On 9/3/2017 1:48 PM, Bob McGraw K4TAX wrote: Depending the type of noise, for repetitive pulse type noise only, the Noise Blanker does it job.

It removes power line noise by muting reception 120 (or 100) times a second, corresponding to peaks in the power line voltage when the arcing occurs. If you chop an audio tone up at 120 Hz, you are amplitude modulating the tone with a 120 Hz waveform. That produces sidebands either side of the tone 'carrier'. This is why you should never use a noise blanker with FT8 and similar modes. The best way to use a rig with WSJT-X is, generally speaking, to make the computer do as much as possible and make the rig do as little as possible. Treat it more or less as a dumb transverter. Don't use the noise blanker, don't reduce the bandwidth below about 2.5 kHz, don't use the notch filter. WSJT-X's decoder works best if you just get the level about right and let it deal with the QRM. 73, Richard G4DYA __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] MH4 Microphone Questions
Bill, I would suggest that it would be much easier to create an adapter for the MH3 to an 8 pin Foster plug - an 8 pin Foster jack to a 3.5mm plug would be quite cumbersome and clumsy in comparison to the size and portability of the KX2/KX3. The PTT connection would be easy (PTT goes to ground), but if you also wanted the UP and DN buttons to work, you would have to add some level sensing circuitry whose outputs would be connected to the UP and down input pins on the Foster connector. Look at the schematic of the KX2/KX3 mic connections and compare the output to the pinout of the K3(S) mic connector and you will see the difficulty. So I think the adapter that you have suggested would not be practical for the KX2/KX3. 73, Don W3FPR On 9/3/2017 6:34 PM, Bill Johnson wrote: Wayne, will you offer a mic adapter to also use with KX@ and KX3? __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Noise Blankers
The advantage of controlling the gain manually is not an "old wife's tale". Rather, it's clearly just a technique that is not for everyone. AGC will reduce the gain according to the strongest signal inside the I.F. passband. Manually riding the "RF" gain ensures that a very weak signal is not affected by a strong signal that is also inside the I.F. passband. Of course that means your ears could be blasted by that strong signal, which is why Wayne included a hard limiter that can be enabled to chop such a signal down to size, making it no louder than the weak signal we want to copy. It has become a moot point for many operators today who cannot read CW if they are hearing two or three (or more) signals within the I.F. passband all at the same time. For them, it's essential to have enough I.F. selectivity to isolate one signal and so AGC is just fine. But some of us have a lifetime of experience sorting out multiple signals with our gray matter between the ears and prefer to continue to do so -- probably until we all become SKs. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Wes Stewart Sent: Sunday, September 3, 2017 3:00 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Noise Blankers Just a couple of points. In the K3(S) there is no "RF Gain" control unless by RF gain you mean "It's not the audio gain gain control." The "RF" gain control operates on the i-f amplifier, which is after the analog noise blanker. In this regard, it is little different from AGC, which operates on exactly the same circuitry. Why some people believe that they are better at controlling i-f gain than the AGC system does is beyond me, but old wife's tales die hard. If this is hard to fathom, watch the S meter as you reduce "RF" gain. The reading increases, no different from letting the AGC do it. Attenuation is a different matter. It operates at RF and is a viable tool.

Re: [Elecraft] Receiver Similaritie
Doug, Actually, I have no idea of what you are referring to. The HRO receivers have the large dial which at that time provided good dial reading vs. frequency readings. That was done with a chart of frequency vs. dial number, and with Elecraft gear, that is done in firmware with the display showing the actual frequency without reference to a graph. There is a crystal filter in the HRO, but it is not like the filters in the Elecraft gear - in those old days, you had to adjust the crystal phasing to peak the signal and it was only useful for CW. I don't know which HRO receiver you are referring to. There is a big difference between them, culminating with the HRO50. My experience with National receivers goes back to the NC-100 which was the predecessor to the HRO series, and has the bandswitching system of the NC-240D (I still have it in the attic - a restoration project for "someday-maybe", but it may never actually happen). 73, Don W3FPR On 9/3/2017 1:46 PM, Doug Millar via Elecraft wrote: For fun- What technical design technique does the National HRO receiver series have in common with the Elecraft series of receivers that is unique to both of them?

[Elecraft] OT - WSJT-X & K3s
My software setup with a K3S, LP-Pan, and Asus U5 is as follows: LP-Bridge creating virtual ports for: NaP3 CW Skimmer Ham Radio Deluxe (last free version, 5.0 Build 2893, using the Logbook as my main log) N1MM or WriteLog for contests Note that HRD versions newer than about 6.2 will not work with LP-Bridge. I am able to run WSJT-X V1.8 rc2 & JT Alert by selecting Ham Radio Deluxe as the radio in WSJT-X, which connects it to the HRD server port. Sometimes changing bands from WSJT-X takes two tries, but otherwise it works fine, even in split TX mode. I'm also using the USB sound card in the K3S for the audio in to WSJT-X. Works great, I've seen decodes down to -26 to -28 in JT65 & JT9. JT Alert automatically sends the info for each contact to HRD Logbook when the 73 message is sent, or you can send it manually. If you haven't upgraded WSJT-X to the new 1.8 rc2 version, you should do so if you are using it for FT8. There are a number of significant FT8 improvements in rc2. There is a WSJT-X user group on Yahoo. Win4K3 also provides virtual ports and a HRD server port, maybe WSJT-X would connect to its HRD server. I have not tried that method. Hope this is of some help. 73, Luther N4UW __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] K3 Jumps To High Output In Data Mode During Power Knob Rotation
The K3 mode button is set to DATA and the transmit mode is DATA A. As I adjust the power output (PWR) knob during continuous transmit, the measured output displayed on the Power Master jumps to a high level. As an experiment, If the output is at a steady 40 W for example, when I slowly and continuously rotate the PWR knob, the output jumps to 150+ watts output during rotation of the PWR knob. As soon as I stop rotating the PWR knob the output is steady at the chosen output. If I choose a different power output during receive, the output is momentarily very high and then drops to the selected output – Overshoot. No Overshoot if I don’t change the PWR knob. This is causing havoc with the amp. Out of curiosity I tried this in CW mode. In CW when I turn the PWR knob during a continuous transmit, the output does not jump to a high level but rather it follows the PWR knob setting smoothly. What may be the issue? 73, Bud W3LL w...@arrl.net __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer
Hi Don and others- Ok.Here is my answer- I don't think I am far off by saying that the unique similarity it is in using switched components to effect frequency coverage of the same tuning coil. In the HRO they had clips you could change over to go to "bandspread" mode on each coil assembly, Elecraft uses relays (switches) to change capacitor values in their bandpass filters so that the same assembly can cover two ranges. Essentially the same thing. I don't think any other companies have used this technique as extensively as National and Elecraft. Your opinion may vary. Doug Dr.Doug Millar EdD.

Re: [Elecraft] OT - WSJT-X & K3s
Bob, Because of logistics, I can't connect the K3s to the computer directly, I am using a powered USB hub. That shouldn't be an issue, if I halt LP-Bridge (which stops control of my logging software), I can use the K3 & P3 utilities. I did try closing LP-Bridge and running WSJT alone (changing the port to 8 which is what the K3s is identified with) but I had similar results. I have tried the different settings in K3s config under PTT-KEY but that hasn't helped either. I really hate to take up a lot of bandwidth on the reflector lest it become an overload & the thread becomes closed. OTOH, for those that want to use their K3s with this program and are not getting it to work, this thread may help them as well. 73, Gary KA1J > Connect the K3S direct to a USB port on the computer.

Re: [Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer
In the HRO-7 coil sets (that I had) they were screws that changed the connections. It was a fun thought experiment for those of us who had HRO receivers. I miss my HRO but mine came to me from W6HUA - Field Gray who was Jack Webb's art direction on the original Dragnet TV shows and well as the feature length movies "The DI" and "Pete Kelly's Blues"). I met Field on 80 meters and he said he'd sell me his HRO IF I promised that if I needed the cash back he'd buy it from me. In College that happened and he took it back for the $100 I paid for it (about $15 in today's money). I was just starting college and some months later he left it at my Mother's home. I then found out he had become an SK from cancer. Decades later another young fellow used to spend hours in my shack listening to it. Eventually I turned it over to him, no charge because that is what I paid, with the same conditions. That made it a great receiver, no matter how good it was or was not by today's standards. That's the Ham radio I grew up in. Most gear was passed onto the next generation with no idea of profit. The price we paid was what it was worth to us for the enjoyment we gained from it. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Doug Millar via Elecraft Sent: Sunday, September 3, 2017 5:46 PM To: Elecraft Reflector Subject: [Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer Hi Don and others- Ok.Here is my answer- I don't think I am far off by saying that the unique similarity it is in using switched components to effect frequency coverage of the same tuning coil.

Re: [Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer
The Hallicrafters SX-73 used three selectable fixed very low value resistors to alter the Q and hence, the passband of three IF stages. Does this qualify? 73, Charlie k3ICH If you happen to own one, I'd strongly suggest checking these resistors. I have two radios in for restoration, where the resistors were off by as much as a factor of 3 which completely screwed up the alignment. -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Doug Millar via Elecraft Sent: Sunday, September 03, 2017 8:46 PM To: Elecraft Reflector Subject: [Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer Hi Don and others- Ok.Here is my answer- I don't think I am far off by saying that the unique similarity it is in using switched components to effect frequency coverage of the same tuning coil.

Re: [Elecraft] OT - WSJT-X & K3s
Gary, I cannot speak to your problems about the communications between WSJT-X and the K3S. But once you have solved that remember that the instructions in the WSJT-X help file are not correct for the K3S (or other Elecraft radios). You must drive the audio to 4 bars on the ALC meter with the 5th bar flashing. Set the desired power with the power knob. Elecraft radios are different than other ham transceivers in how they control the power. Do not attempt to use the audio level to control the power output - that will create a condition affectionately known as "power hunting". The same is true for all soundcard digital modes. Follow the instructions in the Elecraft manuals and ignore the internet advice. 73, Don W3FPR On 9/3/2017 9:19 PM, Gary Smith wrote: I am likely missing something.

Re: [Elecraft] Receiver Similaritie"
The HRO 500 was my dream receiver as a young guy but unaffordable for a teenager. That one had a digital display and was all solid state. Around 1967 or so. The old building that housed the National Radio plant is still there about a mile from where I live.

[Elecraft] HRO Story
Hi Ron, What a great story- the soul of ham radio. I had similar similar experiences. Fellow hams gave me stuff or sold it for little, just to give me the experience of getting on the air. I hope that that still happens. I am involved with the microwavers both terrestrial and EME and that spirit is strong. Part of it is that if we don't get others on, say 5Ghz, there is no one else to talk with. There is more to it, though. I think it has to do with how it feels to have your first QSO or DX, or whatever gets you excited, and wanting others to have the same experience. You are right about the early HRO's, it was a screw change that changed the bandwidth and developed into the funny butterfly swivel. Very similar idea. I'd like to think that Elecraft designers had a similar approach to the guys who developed the HRO and ACS with their economy of parts and innovative and careful engineering- separated by 60years or so. Thanks for responding and for you story.
