Re: [Elecraft] What hardware mods would be best?
Hi Guy, Thank you for your reply. I understand what you are saying. The thought of selling the K3 has crossed my mind several times. However, having played with almost all the rigs of the competitors (TS 990, FTdx 9000, FTdx 5000, IC 7700/7800), I'm always glad to return to my K3. I certainly have no intention to sell my K3 nor can I afford to replace my K3 with a comparable transceiver (assuming there is a TRX that comes close to the K3). Furthermore, doing all the mods for the K3 will cost me over $200,- + shipping + tax. And then they need to be installed as well which unfortunately I myself am not comfortable doing. So it may be the kindest thing to do, it's not the economical thing to do. With no intention of selling my K3 I would rather be kind to my bank account - Maarten, PD2R Member of the PI4DX contest group www.pi4dx.com Elecraft K3 nr:1849 -- View this message in context: http://elecraft.365791.n2.nabble.com/What-hardware-mods-would-be-best-tp7590842p7590850.html Sent from the Elecraft mailing list archive at Nabble.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
Re: [Elecraft] Bluetooth Connection to K2
There's a couple of ways to use Bluetooth with the K2 on my list of mods (internal/external), and there are more on the mailing list.

Over the last couple of months I have sent several emails to various people and support at Elecraft and have never had a reply. This has also happened in the past when I was working with tech support on an issue with my KPA500. I have called to try and have this resolved but it did not get resolved. One email I send a few weeks ago, was answered a number of days later with an apology that my message was in the persons spam folder. However a follow up was not replied to even though it was resent several times. I am sure that this is an error somewhere in the Elecraft email server. I own the complete K line as well as the complete KX3 line. I am a developer of software targeting to the Elecraft products and at least 5 people have bought a K3 or KX3 as a result of my software, so it is important for me to have some feedback at times. I also have provided comments as to bugs that I have found. Could someone please resolved this for me? Thanks for your understanding.

[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.

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
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
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
Bill, With the NB, it will often help to *increase* the RF gain or turn on the preamp. The noise impulse must be above a threshold before it will trigger the blanking function. Keep in mind that setting the NB so the blanking pulse is wider may result in distorted signals. It does just what the name suggests, it puts a blank *hole* in the received signal. The NB is better for fast rise time impulse noise such as lightning and automotive ignition noise. NR will do nothing to help that type noise. I do not believe there is any one magic bullet. What works for one noise may not work for the next one. 73, Don W3FPR On 7/4/2014 10:39 AM, Bill W2BLC wrote: Actually - all of the above.

Re: [Elecraft] [OT] Jim's Dot Stabilizer
Why is it called Lake Erie Swing? Who knows? I always heard it called a banana boat swing but then my CW mentors were from around Lake Erie G. For that matter, why are there two Iambic modes in the first place? The original Curtis Iambic mode completed the element (dot or dash) being sent when [both] paddles were released at the same time. The iambic mode in the AccuKeyer had a logic error - the element memories were set as soon as the previous element completed - that completed the element being sent and then sent the *opposite* element if both paddles were released at the same time. This became known as Iambic B to distinguish it from the original Curtis iambic (Iambic A) mode. Those who learned on an AccuKeyer generally have problems with Curtis and vice versa. For an Iambic B (Accukeyer) user, trying to use an Iambic A keyer generally results in problems with incomplete letters (C, K, R, etc.) while for an Iambic A user trying to use an Iambic B keyer, the problems are generally more severe with extra elements added to the end of nearly any character which ends in alternating elements. 73, ...

Hi Terry, The AuxBus isn't yet supported by the KX3. It's on my list. But it will behave exactly the same as a K3 in this regard.

[Elecraft] Personalizing CW with the K Line
Eric -- Thanks for sharing the recordings. I've heard fists somewhat like that but none quite so distinctive. I tried to figure out what makes the swing sound the way it does. I don't have a scope or any other device to visualize or capture it, so this is just by ear - it seems that his dahs are much more than three times as long as his dits, and that the leading dah in a character that begins with a dah is longer than the following dahs. Maybe someone with the right equipment (and the time to spend on it) could do a better analysis. I would be interesting to know. Both the K3 and the KX3 allow for some personalization (as do many other rigs), by changing the weight ratios -- i.e. the ratios of dit length to dah length and of the element length to the inter-element spacing. There may be other variables in the F/W as well that I haven't looked at. I have never played with it, being an old stick-in-the-mud 3:1 curmudgeon; but I've wondered whether an idiosyncratic weighting would help make a signal stand out in a pile-up or make for better copy in the QRM . . .

Re: [Elecraft] Personalizing CW with the K Line
I wouldn't intentionally develop an idiosyncratic fist to make me stand out, but in the 60's I could identify all of my regular on the air ham friends by their individual fists without every hearing a call. The main characteristic of the Lake Erie swing was dots send at about 40 wpm and dashes at whatever the op chose. It was easy to send very fast dots with a bug (being automatic!), but dashes were much slower for most operators. I think the rationale was the 40 wpm dots brought the overall speed up, even though the op was still sending dashes at a lower capability. Eventually, though, I think the LE swing just became a dialect that propagated through a particular set of operators (Erie Canal for LE swing and marine ops for banana boat swing?), and spread from there. It may not even have been any more efficient--it was just the way you sent in a particular group to identify yourself and be accepted. The same way that non-Southerners start using y'all all over the place an hour after they land at a Southern airport. I don't have a K3, so I don't know if it can be set up to replicate an LE swing. It could if you can independently vary the speed of dots and dashes. You wouldn't have the sometimes difficult corruption of random extra dots and weird variations in dash length, but you could have the best of LE swing which was the lilt and charm of the faster dots. If I were to try it, I'd probably set dash length to 20 wpm equivalent and dot to 40 wpm. It would be fun to try, but not everyone likes to hear a Lake Erie swing--or Southern accents for that matter.

[Elecraft] A Good Antenna Length?
What antenna lengths are you using on 160M with your KX3 or KXPA100 internal tuner? What is best for 160-6 meters? I like making my own antennas with wire. I usually have to give up one band or another cause it just would not tune up on a certain band. I have tried to stay with in these guide lines. -- Jim K9TF __ 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 Good Antenna Length?
Jim, Having one antenna to cover 160 meters through 6 meters is asking a *lot*. But I would suggest starting with a halfwave on the lowest frequency band. If that is a half wave on 160, then the pattern will begin to break into multiple lobes beginning at 20 meters and up. Whether those lobes will be in a favorable direction for you is a different question. Of course, you would feed such an antenna with open wire line or ladder line because those are relatively low loss and losses will increase as the SWR increases. The feedline will have a high SWR on some bands. The length of the feedline makes a big difference in the ability of any given tuner to resolve the impedance at the shack end. A few sessions with the TLW (Transmission Line for Windows) may be helpful in determining the best feedline length compromise that ends up with a usable impedance at the shack end for all bands considered. Of course it will be necessary to know the antenna feedpoint for each band to know how to find the impedance transformation that will be present at the shack end. Antenna modeling can answer that antenna feedpoint impedance question. If the feedpoint impedance at the shack end is out of range of the tuner being used, some additional capacitance or inductance placed either across the feedline or in series with it may be necessary to bring the impedance into a range that the tuner can handle. Thirdly, you need a good current mode choke (balun) to keep RF out of the shack and to provide a balanced to unbalanced transformation. Its impedance must be at least 10 times (more is better) the highest line impedance seen at the place that current mode choke is placed. All the above must be taken into consideration for any antenna. Yes, there is much more to your question than just the lengths of the radiator. Any answers that do not also include the type and length of the feedline may not be able to be duplicated given your particular physical situation. Antennas and feedlines are just like that. Of course an antenna whose feedpoint impedance is matched to the transmission line characteristic impedance can use any length of that feedline, but that is not the usual case for multiband antennas. You will likely have better luck with 2 antennas - one for the low HF bands and another for the upper HF bands - those are normally easier to deal with. The ideal is a resonant antenna for each band, or fan antennas covering multiple bands (I restrict those to 3 bands because the interaction makes tuning frustrating). Good luck on finding that magic length - many have tried over the years and all are compromises. 73, Don W3FPR On 7/4/2014 5:21 PM, Jim GM wrote: What antenna lengths are you using on 160M with your KX3 or KXPA100 internal tuner?

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] A Good Antenna Length?
Just does not have enough isolation from ground. yet it presents a good match. Go figure. A dummy load presents a good match. It just doesn't get out well. Trying to have one antenna do 160-6 meters is just too much if you care about getting out. One antenna can do a fair job on two bands, sometimes, three if done right. But if you expect to have more than a dummy load on multiple bands, you need to plan on having multiple antennas.

Re: [Elecraft] [OT] Jim's Dot Stabilizer
OK, thanks for the recordings Eric. It isn't unique to hams, or to Erie Canal RO's. I worked Coastal Marine from So California in 56-57 while I was a senior in high school. That swing was fairly common, as were a large number of fists I can only categorize as truly sloppy, like an air traffic controller giving a clearance with a mouthful of marbles. His signal was clean however, and very easy to copy. Transmitters afloat were usually powered by M-G sets which often modulated the carrier with a whine. MCW from an audio oscillator was common on 500 Kc [emergency receivers afloat were usually unpowered crystal sets with no BFO], and key down dragged the M-G down. The result was a carrier that chirped, sometimes through the passband of my receiver, a steady whine that chirped, and the MCW audio that chirped, each in it's own key and tempo. I sort of assumed the name came from the RO's on the freighters in the Great Lakes, but never really knew. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 7/4/2014 12:39 PM, EricJ wrote: Here's a couple of recordings of W0BMU and the Lake Erie swing that Buzz mentions.

Re: [Elecraft] A Good Antenna Length?
Why do you need a tuner with a well designed fan dipole. The lengths of each set of wires can be trimmed to allow coax feed. I have 2 fan dipoles here, one for 20, 15, and 10 and another for 30, 17, and 12 meters. Each fed with a single coax. Restricting them to 3 bands simplifies the tuning difficulties associated with interaction. Keeping the wires about 1 foot apart reduces that interaction. I do not mix bands that are 3rd harmonic related on the same coax, it just complicates things - in other words, I do not mix radiators for 80 and 30 on the same coax, the same for radiators for 40 and 15 meters.

Re: [Elecraft] A Good Antenna Length?
Jim, Try 102 feet (or so) for each leg of a dipole fed with twinlead or open-wire line. This is not a close multiple of a half-wave on any band from 160-6 meters, so it stands a chance of providing a reasonable match on all bands. If the internal tuners can't find a match on one or two bands, adjust the length of one or both sides by a couple of feet experimentally. It'll be slightly imbalanced if it ends up off-center-fed, but this won't have much practical impact. At my QTH I use a 4:1 balun (Elecraft BL2) right at the radio to feed this antenna. The BL2 also has a 4:1/1:1 switch. I use the 4:1 setting for all but one band, where the 1:1 setting makes it easier on the ATU. Note that if you don't get to a low SWR when you first tap ATU TUNE, tap again within 5 seconds and the tuner will try more LC combinations. This will nearly always provide a 2:1 or better match unless the antenna presents a very high impedance. The KXAT3 will match a wider range than the KXAT100. For safety reasons, our QRO ATUs put limits on the SWR they will try to match. Use a good ground at the station. If in your installation you experience any RFI at higher power, drop back to a lower level. 73, Wayne N6KR On Jul 4, 2014, at 2:21 PM, Jim GM jim.gmfo...@gmail.com wrote: What antenna lengths are you using on 160M with your KX3 or KXPA100 internal tuner?

Re: [Elecraft] Personalizing CW with the K Line
Back in the day I used relatively fast dots so I could vary my speed without readjusting the weights on the vibrating arm. Dunno whether they were 40 wpm dots or, more likely, somewhat slower than that. And I didn't know that was called a Lake Erie Swing. 73, /Rick N6XI On Fri, Jul 4, 2014 at 1:57 PM, EricJ eric_c...@hotmail.com wrote: I wouldn't intentionally develop an idiosyncratic fist to make me stand out, but in the 60's I could identify all of my regular on the air ham friends by their individual fists without every hearing a call. The main characteristic of the Lake Erie swing was dots send at about 40 wpm and dashes at whatever the op chose. It was easy to send very fast dots with a bug (being automatic!), but dashes were much slower for most operators. I think the rationale was the 40 wpm dots brought the overall speed up, even though the op was still sending dashes at a lower capability. Eventually, though, I think the LE swing just became a dialect that propagated through a particular set of operators (Erie Canal for LE swing and marine ops for banana boat swing?), and spread from there. It may not even have been any more efficient--it was just the way you sent in a particular group to identify yourself and be accepted. The same way that non-Southerners start using y'all all over the place an hour after they land at a Southern airport. I don't have a K3, so I don't know if it can be set up to replicate an LE swing. It could if you can independently vary the speed of dots and dashes. You wouldn't have the sometimes difficult corruption of random extra dots and weird variations in dash length, but you could have the best of LE swing which was the lilt and charm of the faster dots. If I were to try it, I'd probably set dash length to 20 wpm equivalent and dot to 40 wpm. It would be fun to try, but not everyone likes to hear a Lake Erie swing--or Southern accents for that matter.

I tried to figure out what makes the swing sound the way it does. I don't have a scope or any other device to visualize or capture it, so this is just by ear - it seems that his dahs are much more than three times as long as his dits, and that the leading dah in a character that begins with a dah is longer than the following dahs. Maybe someone with the right equipment (and the time to spend on it) could do a better analysis. I would be interesting to know. Both the K3 and the KX3 allow for some personalization (as do many other rigs), by changing the weight ratios -- i.e. the ratios of dit length to dah length and of the element length to the inter-element spacing. There may be other variables in the F/W as well that I haven't looked at. I have never played with it, being an old stick-in-the-mud 3:1 curmudgeon; but I've wondered whether an idiosyncratic weighting would help make a signal stand out in a pile-up or make for better copy in the QRM . . .

Re: [Elecraft] A Good Antenna Length?
A few years ago I took a cue from a usenet posting by Walt, W2DU, that stated that the 102 foot doublet of the G5RV is a good antenna on 80m when fed with twin/window lead and a tuner as it is 3/8 of a wavelength on that band. I carried it further and have a 204 foot doublet fed with 450 ohm window lead and a Palstar AT1500DT tuner and the apex around 40 feet above ground level and the ends around 20 feet.. It may or may not work with the K3's internal tuner as I've not tried feeding it with coax. It works very well for me on 160m, 80m, and 40m. At the moment I am also feeding it on the higher bands until I get dedicated wires up for those bands. As I understand it, the 3/8 wavelength on the lowest band avoids feeding it at the voltage loop so matching is easier. Having a 3/4 wavelength 80m and 1.5 wavelengths on 40m also matches easily in my experience. 73, Nate N0NB -- The optimist proclaims that we live in the best of all possible worlds.

Jim, Try 102 feet (or so) for each leg of a dipole fed with twinlead or open-wire line. This is not a close multiple of a half-wave on any band from 160-6 meters, so it stands a chance of providing a reasonable match on all bands. If the internal tuners can't find a match on one or two bands, adjust the length of one or both sides by a couple of feet experimentally. It'll be slightly imbalanced if it ends up off-center-fed, but this won't have much practical impact. At my QTH I use a 4:1 balun (Elecraft BL2) right at the radio to feed this antenna. The BL2 also has a 4:1/1:1 switch. I use the 4:1 setting for all but one band, where the 1:1 setting makes it easier on the ATU. Note that if you don't get to a low SWR when you first tap ATU TUNE, tap again within 5 seconds and the tuner will try more LC combinations. This will nearly always provide a 2:1 or better match unless the antenna presents a very high impedance. The KXAT3 will match a wider range than the KXAT100. For safety reasons, our QRO ATUs put limits on the SWR they will try to match. Use a good ground at the station. If in your installation you experience any RFI at higher power, drop back to a lower level. 73, Wayne N6KR On Jul 4, 2014, at 2:21 PM, Jim GM jim.gmfo...@gmail.com wrote: What antenna lengths are you using on 160M with your KX3 or KXPA100 internal tuner?

Re: [Elecraft] A Good Antenna Length?
102 feet. There is nothing magic about 102 feet if you feed it with open-wire line. Having a decent match at the feed point doesn't mean squat because feed-point impedance is transformed by the feed line and what you get at the transmitter end won't be the same as at the feed point unless feed-line length is an even multiple of a half wavelength. What IS important is the total length of one half of your dipole plus your open-wire feed. For whatever frequency/frequencies you want an easy match on, make half of your dipole plus feed length as close to an odd multiple of a quarter wavelength as you can. This can be problematic if you want to operate on multiple bands. Don't despair--it's not that hard. You can adjust flat-top length or feed-line length or both to get something you can match on all your bands of interest. Bottom line. Your ability to match is affected by both dipole length and (open-wire) feed-line length. 73, Hank, W6SX __ 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] [P3] Center Freq Left Edge Command
Jim AB3CV wrote
I've been scanning the P3 Programmers manual looking for a way to combine
commands to achieve the effect of making the VFO-A frequency set to the
left edge of the display.
I found a way to trick the P3 into setting the frequency to the left edge
for USB, Data, RTTY and CW or right for lower sideband. It is a combination
of K3 and P3 commands which are mode dependent. I wanted to be able to look
at a signal with a narrowed span with the carrier at the edge. I use DXLabs
Commander to execute the macro commands. It ends up tickling the P3 to do
what you want. I included examples for USB and LSB. I have versions for
CW, Data and RTTY as well. I know it looks silly from a command standpoint
but it works pretty repeatably. I use a series of ifmode statements in
Commander to pick the correct macro commands based on mode {not shown}. The
result when the commands execute is the Carrier goes to the edge and then
the span is set 4.5Khz so you can look at the signal your listening to
across the full display.
Try this for USB: [The wait is a delay that is specific to Commander's

Re: [Elecraft] A Good Antenna Length?
Hi All, When in Key West I have little space for antennas. I built a simple Off Center Fed 40M Windom [ 67/33 or about 44' 22' ]. The long element is a 15' off of the ground while the short element that is not much higher goes up to the peak of my QTH and back down to the other side of my deck. My K2/100 - KAT100 generally runs 75W I've had great success with this antenna on every band 40-10. For 80M and 160M I alligator clip an 8' piece of wire from the end of the short element to my gutter system with provides another 80' of metal to the antenna. Do I burn up 160 80, not big time no but, I make contacts on both bands. In addition, if you ask me what I do for a ground: It's a 40' piece of #14 wire connected to a 2' piece of copper ground rod. Key West is a rock and it's tough to get down any further. Is my 40M Windom Gutter/Rube Goldberg Contraption a dummy load, no! I have the K2ZR/4 contest wallpaper and logs full of contacts to prove it. It 'taint perfect but you do what ya gotta do. And, if the bands are in lousey shape I ride my bike 5 minutes to my shady spot at Fort Zachory Taylor Beach and play some tunes on my Taylor Big Baby guitar.

Re: [Elecraft] K3 - noise reduction query
There is an incredible range of characteristics to unwanted signals that we loosely call noise. The K3 has an array of tools to fight noise, and sometimes they work well in concert and sometimes better alone. There is an IF blanker with adjustable threshold and pulse width - but some impulse noise ay wider than the widest available setting and this is likely to include lightning-based pulses. There is also a DSP-based IF noise blanker. There is a noise reduction, or denoiser function available with a wide range of settings. AGC settings can also affect the operation, and apparent effectiveness, of the DSP-based noise reduction and to some degree the noise blanker. There is a pulse function in the AGC system that you can enable or disable, These settings may all interact to some degree. As the station operator, you have a complete communications system to manage: antenna, feedline, QTH, desired path, time of day and so forth. The radio is one component of the system. The K3 offers a range of tools for you to use, but in the end there is unlikely to be a magic setting that works for everything. If there were, we would have set that at the factory for you (and probably removed the settable knobs for you to adjust)! I suggest that if you are having a severe noise problem, you experiment with the various settings - including AGC threshold and slope and PRE and ATT settings as part of the tool set - and note which work best for you in your system and under which types of noise and mode(s) of operation. You won't hurt anything, and you may learn a lot. And, yes, some radios may work better than others with some types of noise under some circumstances. 73, Lyle KK7P (still learning after all of these years...) NO MAGIC BULLET.

[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 kk7p4...@gmail.com 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. The K3 has an array of tools to fight noise, and sometimes they work well in concert and sometimes better alone. There is an IF blanker with adjustable threshold and pulse width - but some impulse noise ay wider than the widest available setting and this is likely to include lightning-based pulses. There is also a DSP-based IF noise blanker. There is a noise reduction, or denoiser function available with a wide range of settings. AGC settings can also affect the operation, and apparent effectiveness, of the DSP-based noise reduction and to some degree the noise blanker. There is a pulse function in the AGC system that you can enable or disable, These settings may all interact to some degree. As the station operator, you have a complete communications system to manage: antenna, feedline, QTH, desired path, time of day and so forth. The radio is one component of the system.

Re: [Elecraft] K3 - noise reduction query
Joe - Please stop posting personal criticisms of other list posters. This is both rude and against list policy. The Op in this case was asking a reasonable opinion.
