Last night at the radio club meeting the guys were checking out a Yaesu controller box that will operate the az/el rotor for an ARISS contact this June from our local library. No one could get it to work until someone brought in another connecting cable (I think it was a db 9 pin USB cable). Voila! It works. Just lurking on the Elecraft site I see many problems are connected to the incorrect cable or a faulty cable. Take away: don?t throw away those cables you have been collecting over the years. I have fixed a few problems over the years by trying a different cable. David J.

Investigation revealed the PSU board multiplier could produce 210V OFF LOAD with the PSU>LPF jumper disconnected but only 60v when the jumper was connected. Simulating the pin diode current consumption with a resistor also produced the same result. Turned out that R16 which should have been 100 ohm was now 1.2Mohm. Replacing it fixed that problem While talking to elecraft support it transpired that there was an upgrade kit (E850607) that replaces the Q5 FET on the LPF board with a transistor (as usual no reference could be found to it on the elecraft web site!).

My KPA 500 has been running ok for several years on 120 Volts. Today I turned it off on the back , unplugged it and opened the top because I thought I might need to change the voltage tap. I did not need to change it. I replaced the top cover, plugged it in and turned it on at the back. All ok, but when I turned it on with the front panel button the HV reads .1 in standby. If I tap OPER it shows a hard fault and "270V error" .The Manual says this is a 270V supply failure and to recycle the mains power KPA 500 after it is corrected. I tried recycling the power but still faults. I don't have any 270V power from the mains, if I did it would be 240ish, not 270. The fuse block on the back is set to 115V.Any advice would be welcome.Mike, WM5DX. ? --- This email has been checked for viruses by AVG. https://www.avg.com From richgilley123 at gmail.com Wed May 1 08:04:30 2019 From: richgilley123 at gmail.com (richard gilley) Date: Wed, 1 May 2019 08:04:30 -0400 Subject: [Elecraft] Dummy load Message-ID: Hi, Would like a recommendation for a 500 watt dummy load.

I see Don is stepping you through some things as well. Here are a couple of things I was thinking: Since you have a VFO output although low in frequency, I think because the voltage at pin 7 of U6 is so high it is driving the VFO circuit low in frequency. 8.37v seems to me to be the 8v rail in that circuit and since you can't really move that voltage on U6 P7, I might suspect a short between U6 P7 and P8 or at least a short between U6 P7 and the 8v rail. Just something else to look at... BTW - Don or I would be the guy to reply from support if you asked something there. So I just replied to the list so we can keep everything in a single thread. 73, Dave, W8FGU On April 30, 2019 15:49:42 John Wingard wrote: > Hi Don, > > No problem on the delay.

I want to use my hands to screw them on and off. Also, when you have SO239 chassis mounted "Round" connectors (using one large lock washer), then pliers will loosen them every time. What I do is, treat each connector center pin and threads with Caig DeOxit. I do this on all connectors. Now I can put them on and off by hand and there is no Oxidation causing High Impedance RF connections. I do the same on my outside connectors BUT I do also apply 2 inch lbs. of torque. This keeps them from working loose with vibration and prevents oxidation.

In addition to the low VFO frequencies, I had noticed some instability in the frequencies as displayed. Don suggested that I insert a 10-15pf cap between the source of the Q19 FET and ground. I did that late last night and not only did that clear up the frequency instability, but now my VFO frequencies are up about where they are supposed to be (8912 at 4000 and 12013 at 7100). I don't know if adding the cap did all of that or perhaps the process of reflowing the connection on the source pad of the FET straightened things out. So now I'm back to the original problem of the 8.37 V at R30 which has not changed. Don also wanted me to order two J310 FET from Elecraft, but in light of this latest finding I was waiting to see if he still wanted me to do that. 73 de John WB4GLJ On Wed, May 1, 2019 at 9:03 AM Dave Van Wallaghen wrote: > Hi John, > > I just got back in town and I know I'm late into this.

I want to use my hands to screw them on and off. Also, when you have SO239 chassis mounted "Round" connectors (using one large lock washer), then pliers will loosen them every time. What I do is, treat each connector center pin and threads with Caig DeOxit. I do this on all connectors. Now I can put them on and off by hand and there is no Oxidation causing High Impedance RF connections. I do the same on my outside connectors BUT I do also apply 2 inch lbs. of torque. This keeps them from working loose with vibration and prevents oxidation.

The "Cantenna" serves well for the purpose of checking the amplifier operation and determining if a problem observed is the result of "RF-in-the-shack" or an amplifier problem. A precision 50 ohm load is not required for those purposes. If you intend to do calibration operations, then the "Cantenna" is "iffy" unless you can be certain it is 50 ohms non-reactive (check with an antenna analyzer at the frequency of interest). If you need to do calibrations and make measurements of actual RF voltages, then you do need a known 50 ohm non-reative dummy load, and the "cantenna" types likely do not 'hack it'. 73, Don W3FPR On 5/1/2019 2:32 PM, Bob McGraw K4TAX wrote: > Those gallon bucket dummy loads, often referred to as "Cantenna" loads, > are inexpensive and generally work OK to a limit.?

(the latter could sort of be achieved today with the software sending the right commands of course) Cosmetically, the unit's display is starting to look & feel a little clunky by 2019 standards, but this is such a minor thing. But honestly the K3S has left me wanting for so little that it's somewhat difficult for me to imagine altogether very many ways to improve it, though I've only been operating with it about a year.

Is the output power at 20 to 25 watts? If so, so far so good. Now try a TUNE/DISPLAY (hold both buttons at once). Is the power near 50 watts? If so, you have proper power control and the problem is with the LED display. OTOH, if the actual power in both cases above goes to 100 watts or more, then the first step is to replace KPA100 D16 and D17. If that does not fix things, there is likely another problem in the KPA100 wattmeter, likely KPA100 U6 - but get back with the information before replacing it, there are more tests to verify or deny that possibility. 73, Don W3FPR On 5/3/2019 10:25 PM, Bill Coleman wrote: > I?ve recently seem a problem with my K2/100.

I wasn't panicking but I felt much better after reloading the files updating the firmware to 5.67. Turning off the P/S, unplugging the power to the radio and from the radio to the P3, and, probably most importantly, restarting the computer did the job. Support from Don on a Saturday night is a big reason why I remain a loyal, delighted customer, with a K3S, P3/SVGA, K-Pod, and KPA1500. I've had Elecraft since 2009, which is the longest I've owned one radio (actually a K3 and then a K3S) since being first licensed in 1964.

KPA-500 HV is 10 Volts Message-ID: <64dde9f9-0be3-e799-fc8b-fda322aa1433@ChesBayVA.com> Just got a repaired KPA-500 PA/LPF module from Elecraft and installed it in my KPA-500 Amp. I carefully (I thought) reassembled everything. When I powered-up the unit and tapped "HV" I get numbers between 9 and 11 volts (expecting ~ 65 or 70 Volts). I know this is not right. I double-checked the 270V line to the PA module and the top cover interlock. Surely I am doing something stupid.

KPA-500 HV is 10 Volts Message-ID: "When I powered-up the unit and tapped "HV" I get numbers between 9 and 11 volts (expecting ~ 65 or 70 Volts)." I'd suggest measuring the actual HV rail at the PA input spade terminal. That will tell you if you have a real low voltage problem or a voltage sensing problem. The interlock switch will need to be defeated which is not difficult but I leave that to your ingenuity. If the voltage really is low then (switch off) disconnect the 60 V bus from the PA module (switch on) and measure again. My HV supply is 80 V unloaded. The interlock switch is there to stop you doing this so don't defeat it without considering the risks and taking appropriate precautions. 73, Andy, k3wyc From kevinr at coho.net Sun May 5 00:11:18 2019 From: kevinr at coho.net (kevinr) Date: Sat, 4 May 2019 21:11:18 -0700 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: Good Evening, ??

I?ve built and owned Elecraft gear since 1999. Still have my KX3 and KX2. I bought a Flex 6600M rig and it was the best radio I?ve owned in years. But Flex messed with the firmware to where if you were in full QSK mode and used the internal ATU a loud relay would start clicking when sending CW characters, messing with the normally quiet QSK changeover from RX to TX. The reason given for this firmware change was that when the ATU was engaged in full QSK mode the receive signals would be 10db down as opposed to zero db loss without the tuner in line. To be honest I never noticed this problem but Flex, in all of their wisdom, made the disruptive change. IMHO this firmware change completely ruined a very FB CW rig. Perhaps the folks at Flex are not as CW-centric as the Elecraft folks. In terms of a K4 I would certainly love to see a beautiful 8? or large front panel display. This is the direction all modern radios are going?.just look at the YaeCommWood offerings plus the Sun MB1 rig. While the P3 and PX3 displays are OK, a full 8? or larger hi-res display is breathtaking and extremely useful. So, why not a K4 with a big hi-res screen? I?m ready for it?make it happen!! 73, Joe W2KJ I QRP, therefore I aim > On May 5, 2019, at 11:16 AM, Rose wrote: > > Bert, > > Then why not just purchase the Flex? > > 73 ! > > K0PP > > On Sun, May 5, 2019, 09:11 Bert Craig wrote: > >> I'm in the comparison stage of planning my next, and likely final, HF rig >> purchase.

Agreed. If a radio has an internal computer, it had better be transparent to the operator, including not taking forever to boot up and not being subject to problematic software upgrades.

This stubbornness, I suspect, was born out of a sense of technological arrogance. In the early 1970s, the Swiss watch industry, enamored with their mechanical movements, refused to embrace quartz technology. That decision would result in decades of rapidly declining Swiss watch sales. The ultimate irony is that today many Swiss watches make use of Citizen internal movements. Conversely, there are companies like Apple. Apple, was able to leverage existing technologies and make them ?better? for their end-customer. In other words, confront the paradigm shift head-on, know what your end-customers will most value (even if they don?t know it today) and positively exploit the emerging technologies. Elecraft is more of an Apple than it is a Swiss watch company. I have no doubt they will positively exploit emerging technologies and deliver products with features that we haven?t even thought about today. Have faith, all. And, by the way, as we wait, we?ll just "have to live with" our worldclass transceivers; not a bad position to be in if you ask me. 73, Joe W1GO > On May 5, 2019, at 12:41 PM, Drew AF2Z wrote: > > I've never doubted that Elecraft would produce a great CW rig, if not the best! > > The only thing I'd be concerned about is the operator interface.

So if you need a stronger signal just tune your Siglent to 1/3 of 50 mHz which is 16.6666 etc mHz. The third (and 5th, 7th, etc ) harmonics should be plenty strong. You may need to crank your Siglent up a bit to get the desired diode action. In theory this idea should work.

Not really looking forward to touchscreen controls here, though I suppose they are inevitable in modern rigs. Touch/mouse would provide a lot of flexibility. The trick would be to use "real" controls for things you do most often, and make sparing use of touch for basic operation. Of course touch has some cool aspects like tap/drag, pinch/spread, etc., that can be applied to new features such as an advanced panadapter. > > I think modern rigs could benefit by having an optional keyboard interface-- no need of an intermediary computer, just a dedicated plug-in (or wireless) keyboard that could be used to access all the rig controls and menu items. Definitely. > I wonder if Elecraft will stick with the high portability/low power consumption design. Those things aren't really important to me. I wouldn't mind a larger rig. We're dedicated to providing gear that won't break your back, runs efficiently, and can be used for portable applications when needed (Field Day, DXpeditions, emcomm, RV, etc.). A new radio would have be somewhat bigger to accommodate a large display, but it would not have to be twice as large, weigh 2 to 3 times as much, or consume 3 to 4 times as much power as a K3S. All of the K3S's newer competitors have one or more of these non-portable characteristics, and some have all three. 73, Wayne N6KR From wes_n7ws at triconet.org Sun May 5 13:27:25 2019 From: wes_n7ws at triconet.org (Wes) Date: Sun, 5 May 2019 10:27:25 -0700 Subject: [Elecraft] Prospective K4 In-Reply-To: <810500DF-DE94-47DF-8B7A-115ABE168A9E@charter.net> References: <328523bb-764e-7c51-204d-008fc34b0f1a@inkbox.net> <0811f46c-2d69-40a5-8feb-875153bdecec.maildroid@localhost> <810500DF-DE94-47DF-8B7A-115ABE168A9E@charter.net> Message-ID: <19d43f54-c19d-acfe-d2e1-e2d1000adaa1@triconet.org> How are you liking the radio performance wise??

SDRs (using wideband direct sampling and no crystal filters) process all incoming receive samples in large packets.This provides some economies of scale for signal processing algorithms, but it does impact latency. In some cases the impact can be dramatic ? like 100 to 200 ms QSK delays. An alternative is to process only the pan adapter data in large packets. If such data is only being used for a spectral display, the latency is not an issue. In CW mode or in other situations where latency must be low, time-domain DSP routines can optionally be used for processing data from the slices (signal channels) used for demodulation. Latency as low as just a few milliseconds is then possible, contingent on the level of filtering required. Filtering trade offs can be automated, e.g. in proportion to the QSK delay setting.

That goes so far that they use it with one setup, that might be the wrong one for a given frequency or antenna or mode. With Windows they choose their own language when they set up the PC to make the life easier. That may not work every time, like my case I could not set up Fldigi on Hungarian keyboard PC though W10 was English. So moved to a second PC. With SDR trx that option will never happen so they insist on simple radios, asking for manual translation.... For those a very simple menu system is welcome. K3 is a good, keep that practice, no multilevel menus are received well. Complicated SDR is not for them.

Not really looking forward to touchscreen controls here, though I suppose they are inevitable in modern rigs.Touch/mouse would provide a lot of flexibility. The trick would be to use "real" controls for things you do most often, and make sparing use of touch for basic operation. Of course touch has some cool aspects? like tap/drag, pinch/spread, etc., that can be applied to new features such as an advanced panadapter. > > I think modern rigs could benefit by having an optional keyboard interface-- no need of an intermediary computer, just a dedicated plug-in (or wireless) keyboard that could be used to access all the rig controls and menu items.Definitely.> I wonder if Elecraft will stick with the high portability/low power consumption design. Those things aren't really important to me. I wouldn't mind a larger rig.We're dedicated to providing gear that won't break your back, runs efficiently, and can be used for portable applications when needed (Field Day, DXpeditions, emcomm, RV, etc.). A new radio would have be somewhat bigger to accommodate a large display, but it would not have to be twice as large, weigh 2 to 3 times as much, or consume 3 to 4 times as much power as a K3S. All of the K3S's newer competitors have one or more of these non-portable characteristics, and some have all three.73,WayneN6KR______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html From elanzl at sbcglobal.net Sun May 5 15:34:45 2019 From: elanzl at sbcglobal.net (Eric Lanzl) Date: Sun, 5 May 2019 19:34:45 +0000 (UTC) Subject: [Elecraft] Elecraft SSB Net for Sunday April 28-2019 References: <2061454863.1646464.1557084885557.ref@mail.yahoo.com> Message-ID: <2061454863.1646464.1557084885557@mail.yahoo.com> Here is the list of stations from the net last Sunday.

See no possibility of anO3. The K3 is a super radio until one hears clicking in earphones while running 7QP in full breakin. That was not a factor in the O?s. For those of us with bigger hands/fingers the K3 is not optimum. Also too many menus. Nothing on the present market suits me, though the K3 is on my desk. Make a K4 bigger with many fewer menus. I am not interested in hauling my radio around the world, so bigger suits me just fine. Add solid state keying to reduce clicking especially in earphones. I am a CW op. Give me an optimized CW rig with FSK and for others SSB.

This stubbornness, I suspect, was born out of a sense of technological arrogance. In the early 1970s, the Swiss watch industry, enamored with their mechanical movements, refused to embrace quartz technology. That decision would result in decades of rapidly declining Swiss watch sales. The ultimate irony is that today many Swiss watches make use of Citizen internal movements. Conversely, there are companies like Apple. Apple, was able to leverage existing technologies and make them ?better? for their end-customer. In other words, confront the paradigm shift head-on, know what your end-customers will most value (even if they don?t know it today) and positively exploit the emerging technologies. Elecraft is more of an Apple than it is a Swiss watch company. I have no doubt they will positively exploit emerging technologies and deliver products with features that we haven?t even thought about today. Have faith, all. And, by the way, as we wait, we?ll just "have to live with" our worldclass transceivers; not a bad position to be in if you ask me. 73, Joe W1GO>On May 5, 2019, at 12:41 PM, Drew AF2Z wrote:>>I've never doubted that Elecraft would produce a great CW rig, if not the best!>>The only thing I'd be concerned about is the operator interface.

So if you need a stronger signal just tune your Siglent to 1/3 of 50 mHz which is 16.6666 etc mHz. The third (and 5th, 7th, etc ) harmonics should be plenty strong. You may need to crank your Siglent up a bit to get the desired diode action. In theory this idea should work.

SDRs (using wideband direct sampling and no crystal filters) process all incoming receive samples in large packets.This provides some economies of scale for signal processing algorithms, but it does impact latency. In some cases the impact can be dramatic ? like 100 to 200 ms QSK delays. An alternative is to process only the pan adapter data in large packets. If such data is only being used for a spectral display, the latency is not an issue. In CW mode or in other situations where latency must be low, time-domain DSP routines can optionally be used for processing data from the slices (signal channels) used for demodulation. Latency as low as just a few milliseconds is then possible, contingent on the level of filtering required. Filtering trade offs can be automated, e.g. in proportion to the QSK delay setting.

I suggest this as a compromise: Provide basic radio (say 50w with 13.8v output devices for portable use). I bought a K3/10 to start out. Then a KXPA100. Offer 200w 50v final as option. Basic radio would have manual controls like the K3/K3s. Offer a touch-screen option which would include P3 capability in a separate cabinet with mouse/keyboard I/F. Keep the firmware concept flexible with upgrades with an efficient cpu and OS. Have IQ baseband output for running various digital modes on customer's computers (maybe with wifi so one could use an ipad or equivalent). Or maybe bluetooth. I'm sure wireless is a rapidly changing field so will not speculate what would be best.

In-Reply-To: References: Message-ID: Frank, All of FT8 is supposed to fit in a voice grade channel, 2.1 KHz -3.0KHz. The S/N numbers you see are referenced to a 2.5 KHz. B/W. However, having said that, there are some operators that go out to just short of 3.0 KHz. I leave my receiver open to this larger number. If your question is really asking what is the signal bandwidth that is a different question than I just answered. My recommendation is to set your DSP bandwidth, the knob selectable B/W, equal to the roofing filter B/W plus just a little and not worry too much about it. You will see the majority of signals and the software will see the available calls and stations calling you. The downside is greater interference and some AGC issues caused by some station you really didn't want to work anyway. I'm not trying to be glib in answering you in the latter part of my comment above, but there is no easy single answer. I do believe most everyone is operating as I do, within the SSB filters of their radio. 73, Barry K3NDM ------ Original Message ------ From: "Frank O'Donnell" To: "elecraft at mailman.qth.net" Sent: 5/5/2019 5:54:34 PM Subject: [Elecraft] K3S filter for FT8? >I'm sure this is a well-covered question, but I'm getting so many hits on search terms that it's difficult to find past discussions. > >On the K3S or K3, what filter(s) are people finding optimal for FT8?

I sincerely hope the K3s remains among the product offerings, as a new bigger radio will be less suitable for some portable uses even if it is designesd with portability in mind. This would also help the resale value of the K3(s). Generally, I see Elecraft radios holding their value much better than other brands in the face of new model releases. 73, Erik K7TV From raysills3 at verizon.net Sun May 5 18:35:10 2019 From: raysills3 at verizon.net (Raymond Sills) Date: Sun, 5 May 2019 22:35:10 +0000 (UTC) Subject: [Elecraft] Prospective K4 In-Reply-To: <8a758c19-23fc-b1ed-bb09-33a60b6038ca@cis-broadband.com> References: <8a758c19-23fc-b1ed-bb09-33a60b6038ca@cis-broadband.com> Message-ID: <157362764.542847.1557095710160@mail.yahoo.com> And.... it's best to remember that Elecraft rigs are products...perhaps tools, but not investments. ?Maybe 50 or 100 years from now, they will be "collectibles" and become an investment (of sorts) at that point. ?

That's a habit formed when working JT65+JT9. You sometimes find interesting stations to work well above 2.7 kHz.

I've got "nearly K3S" radios for the added cost of less than $600 per radio (two RXs). 73, Jim K9YC From jim at audiosystemsgroup.com Mon May 6 01:57:50 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 5 May 2019 22:57:50 -0700 Subject: [Elecraft] Elecraft Digest, Vol 181, Issue 4 In-Reply-To: <91517203-a993-4ca2-9cc9-641b0d54a66e@iPhone> References: <91517203-a993-4ca2-9cc9-641b0d54a66e@iPhone> Message-ID: <5ab34bbe-46c3-f6ee-a3b8-a027377dac77@audiosystemsgroup.com> On 5/5/2019 1:19 PM, Email Service wrote: > The K3 is a super radio until one hears clicking in earphones while running 7QP in full breakin. W6JTI and I just ran 18 hours of 7QP with full QSK and no clicks. Two stations with a K3, KPA500, and KAT500. One station also had P3/SVGA. N7N activated six NV counties, making 2,200 QSOs. About 350 were SSB. You should investigate what might be causing you to hear clicks. Perhaps in your station or outside your station, like passive intermod. 73, Jim K9YC From jim at audiosystemsgroup.com Mon May 6 02:15:42 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 5 May 2019 23:15:42 -0700 Subject: [Elecraft] K3S filter for FT8? In-Reply-To: References: Message-ID: On 5/5/2019 2:54 PM, Frank O'Donnell wrote: > On the K3S or K3, what filter(s) are people finding optimal for FT8? IF selectivity is provided in DSP, not with plug-in filters as with older radios. Plug-in filters for these radios are ROOFING filters -- they protect the DSP from overload from strong signals outside the chosen IF bandwidth. Nearly all WSJT modes are designed to work with the full bandwidth of an SSB channel -- about 2.7 kHz, which is the bandwidth of the stock roofing filter that comes with a K3 or K3S. In fact, Joe Taylor, K1JT has long advised that rigs should always be set for that wide bandwidth for his modes, and let WSJT-X do the required signal processing to separate stations. There's a fundamental reason for that -- for most physical networks, and for digital simulation of physical networks and devices, any change in amplitude response has an associated change in the phase response. Decoding systems, including the human hearing system, are degraded by steeply changing phase response. We learned about this in pro audio world in the '70s, thanks to the work and teaching of the late Richard Heyser. THAT'S why Joe advises as he does. In the last few years, RTTY operators have learned this and taken it to heart. Gone are the recommendations for "double-humped" filters, with their associated phase distortion -- the top operators now use 400-500 Hz filters for RTTY. A major shortcoming of the K2 is that when the multi-stage crystal filter is realigned for narrow SSB bandwidth, the frequency response looks like a cross-section of the rocky mountains, making SSB speech more difficult to copy. The radio sounds great when the TX filter is used for RX, which is at full SSB bandwidth. 73, Jim K9YC From jm-ec at themarvins.org Mon May 6 03:11:51 2019 From: jm-ec at themarvins.org (John Marvin) Date: Mon, 6 May 2019 01:11:51 -0600 Subject: [Elecraft] WWV 100th Anniversary Event Message-ID: <6441d81c-c47a-69d2-5dad-623bb7cb9616@themarvins.org> Just a quick note, WWV is celebrating 100 years on the air this October, and NCARC (I'm a member) is sponsoring an event with NIST on the WWV property from 9/28 - 10/2. More information can be found at http://wwv100.com. So, how is this Elecraft related you might ask?

I estimated that guys hobby (they were all alike and traveling as a group) probably cost him $100,000+ and in five or ten years he will probably sell it all for new stuff at a great loss.

That is what I use in my mobile station and it provides about 250W due to the FCC amplifier gain requirements. I am fine with it, as that is what I have and higher power may affect the vehicle. I have seen someone post a modification to remove an attenuator in the amp and recalibrate the power meter, but I would assume that Elecraft will not be allowed to do that, as the FCC Cert holder. 73, Mark W7MLG From ardrhi at gmail.com Mon May 6 10:16:32 2019 From: ardrhi at gmail.com (Gwen Patton) Date: Mon, 6 May 2019 10:16:32 -0400 Subject: [Elecraft] Prospective K4 In-Reply-To: References: <129d0928-d6a2-641b-c302-8eb95ccdbd93@k8jhr.com> <4ec92c31-fa34-91ba-485c-5f68d8723651@bell.net> <1571168.Cje8jsEvI4@linux-hq78> Message-ID: I'm holding out for the KX9, the one with noetic circuits printed directly on the space-time continuum.

See the VFO CRS menu description. The other neat feature (which I use all the time) is to set VFO OFS to ON which allows the VFO B knob to move VFO A in large steps (according to VFO CRS) except when either RIT or XIT are on.

He had a big old Cadillac that had been fitted with the extra-large alternator for the towing kit to support his high-power mobile station.? Legend has it that he would sometimes set overhanging tree branches on fire because of the corona discharge from the end of the antenna.

What if you're running a KW, and gave a call on 20M. Suddenly, the guys brakes in the vehicle next to you locked up causing a multiple vehicle crash? I realize this is an extremely hypothetical and unlikely case, but these smart vehicle computer systems can't be all THAT immune to all sorts of RFI. I know the cruise control my 2000 Dakota would mysteriously jump 5 MPH if I keyed up with only 25 watts on 222MHz. It would return to it's previous setting when I un-keyed. VERY disconcerting eh? 73, Charlie k3ICH This begs the question: Why KX3s with KPA500s? That is what I use in my mobile station and it provides about 250W due to the FCC amplifier gain requirements. I am fine with it, as that is what I have and higher power may affect the vehicle. I have seen someone post a modification to remove an attenuator in the amp and recalibrate the power meter, but I would assume that Elecraft will not be allowed to do that, as the FCC Cert holder. 73, Mark W7MLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From scott.small at gmail.com Mon May 6 12:14:08 2019 From: scott.small at gmail.com (Tox) Date: Mon, 6 May 2019 09:14:08 -0700 Subject: [Elecraft] Mobile high power In-Reply-To: <50EA7432-010F-49FF-8019-F90E24AE23EB@elecraft.com> References: <003501d50417$1c6fde30$554f9a90$@erols.com> <29F4DB7C-B7B7-4F65-B7EB-42B08C417E45@elecraft.com> <1941352579.687242.1557158567041@mail.yahoo.com> <50EA7432-010F-49FF-8019-F90E24AE23EB@elecraft.com> Message-ID: Tire sensors are wireless, and the protocol has been reverse engineered.

So, they are relatively immune to external RF fields. On the other hand, they are frequently not designed to withstand a powerful onboard transmitter, unless specifically designed for a particular market, say police/fire/ambulance. In the case of those vehicles, the assembly plant typically installs bonding/ground straps to bond all major metal panels. Unfortunately, regular customers can't get those kits installed at the plant for them, and they aren't very effective as an aftermarket kit, because the customer would have to scrape the paint down to bare metal and access locations that might be completely closed off after assembly to install said straps. The other unfortunate effect of designing for police/fire/ambulance service, is that all those radios are now VHF/UHF and up. No more HF radios. They went out with the state-wide sheriff's networks of old that ran on 40 MHz or so. So, that leaves the amateur radio HF operator twisting in the wind, both for onboard interference from vehicle electronics, and susceptibility of same. I heard that one OEM had declared that no one used HF any more, because they scanned the FCC database looking for amateur station assigned frequencies (ala commercial stations which are assigned fixed channels or groups of channels) and finding none, reached the conclusion that no one is using those bands any more. Thus, all frequencies below 30 MHz are not protected, except for the AM broadcast band in the US, and MW in the EU. OEMs are concerned that their onboard entertainment radios (AM/FM/Sirius/XM) and their tire pressure monitor and remote keyless entry systems have no interference, but everything else can go to pot. At one time, I'm aware that at least one OEM tested using an Icom IC-706 with those dummy-load like 1-inch coil resonated antennas, but I don't know if that is any longer the case. The ARRL TIS (Technical Information Service) maintains a database of information on mobile installations, including official documentation (if any) from various vehicle OEMs on suggested mobile installation guidelines. Some OEMs used to come to Dayton with sample mobile installations, and answer questions but I've not seen them do this for some number of years. Hope this helps. 73, -- Dave, N8SBE From jim at audiosystemsgroup.com Mon May 6 13:30:30 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 6 May 2019 10:30:30 -0700 Subject: [Elecraft] Mobile high power In-Reply-To: <29F4DB7C-B7B7-4F65-B7EB-42B08C417E45@elecraft.com> References: <003501d50417$1c6fde30$554f9a90$@erols.com> <29F4DB7C-B7B7-4F65-B7EB-42B08C417E45@elecraft.com> Message-ID: <932b41bc-960a-ed98-ba3c-86f913aa13b2@audiosystemsgroup.com> I took delivery of my 2006 Toyota Sequoia SUV in time to make multiple trips moving from Chicago to NorCal, carrying stuff like master tapes, tech equipment, and other things I didn't want to fight with the moving company about their losing it or breaking it. Prior to the first trip, a ham friend opened his heated garage to me in a Chicago winter and helped me pull power from the battery and mount an antenna mount on the roof rack. Using an ohmeter, we found that there was no continuity between adjacent screws -- some were insulated by paint, so we had to poke around to find one to bond coax shield to the chassis to make it a counterpoise. I ran HamSticks, and found that they worked well enough, and mostly worked CW.? I mostly used an IC746 on the seat beside me, and found that the antenna tuner was a big help with the narrow resonances of short antennas.? That vehicle, which I still own, has bodacious RFI, but in the process of moving cross-country, I had no time to think about fixing it. I had mostly run one band leaving Chicago, and noticed that the ventilating fan sped up when I transmitted. No big deal. But driving through the very isolated NV desert the next day, I fired up on 20M, got three responses to my CQ, and then noticed that my speed had dropped to 20 mph -- RFI had gotten into one of the vehicle's computer and put me in "limp home" mode. Luckily, I had tools with me -- pulling fuses didn't reset the computer, so I had to pull the positive battery lead to reset the computer. This weekend, K6EU and I ran 6M FT8 and MSK144 from that vehicle with a K3 to a 6M whip. RF got into everything, which I tamed with a dozen or so chokes formed by 2 turns through a #31 clamp-on, multiple chokes in series on each cable, including the coax at the antenna. That shouldn't be a surprise -- the vehicle chassis is half of the antenna.? The clamps didn't help his Apple phone, which locked up in the presence of 100W of 6M. My Motorola phone had no RFI issues at all, even when we parked at county lines and ran a KPA500 from a generator to a 3-el Yagi 6 feet from the car. The objective of Tom's operation was to activate two rare grids for 6M grid chasers. 73, Jim K9YC On 5/6/2019 8:31 AM, Wayne Burdick wrote: > My Prius is so dependent on embedded processors that I take no chances -- I run only 10 W mobile.

Message-ID: So you want a new radio? So do a survey. Remotehamradio.com is running a network of radio stations for their users. Flex is growing their remote system but they still haven't got a turn the antenna rotator macro built in. You can band switch between your yagis you just can't turn them. Pointing on the dx spot list should in fact turn the antenna and tune the frequency on your radio, your amp following of course. So on the one hand we want a radio with a tuning knob, at least some of us do. We also want our radio talking to a screen, mouse, whatever to do the click change operate kind of stuff. So the new deal now that Elecraft has built a big amp for us is to go after all the add on software stuff that drives you guys nuts trying to get it to work with com ports etc. Elecraft needs code writers since the new box will be a radio but the magic will be in the remote capabilities and the tuning from dx spots and cw reader, spotter, stuff. More and more code i hear on dxpeditions is machine generated. Macro stuff. Allows the op to log you while the radio going QRZ up 10. He still has to enter your call but that's it. Entering your call logs you and tells you your 5NN dah id dah. So the next radio from Elecraft K4-9 will be the interface that does all the magic and the radio will still be there to tune around when you are in front of it. I am a remote guy. I live in a city and my station is 2000 miles away. I use a website to talk to it. What do I want next. I want a panadaptor on the website so I can SEE who is talking to ATNO so I can zerobeat that guy. No more tuning. Click. That is the future and it is here now and every new box will have an app that does everything and is always upgradeable. It can be on a phone or a table or laptop. The leaders are Elecraft and Flex. Nobody else comes close. Remote Rig is pass?. It has to be in the radio now. And available to whomever you authorize. Every serious Contest station has remote capability now.

But that wasn't the oldest WWV site. The original 1919 site was at the Bureau of Standards in Washington D.C. WWV moved to College Park MD in 1931 then to Beltsville in 1932. There was a major fire in the Beltsville WWV building on 1941, which forced a temporary move to a nearby building. WWV moved to a new site in Greenbelt i n 1943 where they stayed until they moved to Fort Collins in 1966. 73 Frank W3LPL ----- Original Message ----- From: "Phil Kane" To: elecraft at mailman.qth.net Sent: Monday, May 6, 2019 6:23:24 PM Subject: Re: [Elecraft] [OT Elecraft] WWV 100th Anniversary Event On May 6, 2019, at 00:11, John Marvin wrote: > Just a quick note, WWV is celebrating 100 years on the air this > October, and NCARC (I'm a member) is sponsoring an event with NIST on > the WWV property from 9/28 - 10/2.

They seem to currently be in the phase of using distributed localized grounding points (with several ground return wires per location), a kind of hybrid grounding system, if you prefer. I've always run a pair of wires back to the battery, but with one important difference. I tie the ground side of the pair near the battery end to the chassis terminal that the battery uses to 'ground' the negative to the vehicle chassis. This way, if the battery negative opens (either because of a loose terminal clamp or a defective battery-to-chassis connection), you won't get a load dump of the entire vehicle's current through your radio's ground wire, radio chassis, and antenna coax shield to wherever you've mounted your antenna. No OEM will ever recommend connecting the negative return of any accessory to the battery negative terminal, because of this. Folks that do this risk a 'thermal event' involving their gear if a load dump occurs. Finally, if your DC power cable came with a fuse in the negative lead, bypass it/take it out! Otherwise, you can blow the fuse in the negative, and put all your transmitter power load (30A peak for a typical 100W HF rig) down your antenna coax shield to (again) where ever you mounted your antenna. Also, put an inline fuse near the battery end in the plus DC lead, to guard against any shorts to chassis in the run to the rig. Most aftermarket installations don't do much to protect the added wiring, and it could chafe and get cut into someplace. Better to blow the fuse at the battery end, than to have another 'thermal event' burning up the wire.

Typical police/ambulance radios ran 110w MOT stuff. Some commercial ran 25-50w with smaller footprint sized radios. Nearly all is either high-band VHF 150-174 MHz) or UHF (450+). All were wired with neg tied to the chassis. However the local refuse company trash hauler trucks ran 42-MHz, and the state DOT still uses Low-Band VHF (47 MHz, I think). A lot of commercial radio was going trunked and into 900-MHz band (in urban areas). Low-band antennas were sensitive to good grounds (like HF ant are). Makes sense that the "cop cars" would be special-made for comms (interesting to see the 150mph speedometers). Most I installed in the 1990's were Crown-Vics; now they run Tauras' or other full-size sedans. Quite a few SUV's and PU's in use, as well. I had a 50w dual-band FM mobile with mag-mt whip on my 2002 Toyota Tundra and speed-control was sensitive to 2m transmissions (sped up about 5mph), but my 2015 F250 diesel seems immune to RFI. I run the 50w dual-band, KX3 plus KXPA100 on HF/6m and 2m-SSB at 150w. 12v power is run with two No. 8 wires from the left battery. Neg. is bolted to engine chassis about six inch away from battery and normal battery neg cable used to engine. Most of the equipment is turned on by a HD relay in the HD power cable with relay controlled from one of the front panel switches.

Yes, but in those days, there was a lot less electronics in vehicles to generate noise, and VHF/UHF is VERY different based on wavelength. What we got away with 30 years ago for VHF/UHF is bad practice for HF today. I agree completely with all of N8SBE's advice.

Absolutely. The last new product I was involved with at HP had an Intel based PC motherboard, and the instrument ran Windows. The instrument software was just a Windows app. I thought then it was a terrible idea and still do. PCs are commodities, their lifespan is way too short for anything other than a standalone PC. Putting one into a high quality, specialized instrument/radio/whatever makes no sense at all.

Ed Eklin, K8ZZ, is 300 counties shy of transmitting from all counties in the 50 states. He drives Hondas. He is available on QRZ and enjoys questions. He has learned how to transmit with his K3, KX3 with 100 amp, etc., over the years without having any auto related computer issues. He just gave another great lecture at our radio club explaining the grounding issues with mobile operation. Dave K8WPE David J.

But apparently it's an effect that would need to be taken into account by anyone interested in very precise frequency measurement at the sub-Hz level. I wonder if there are any comments here, or thoughts on managing it while doing FMT work? I just ordered a new K3S as a first-time user, and FMT (as an absolute rookie) is one area I'm interested in.

I've always come in with a measurement of better than 1 Hz.?? Not at all bad for amateur radio equipment.?? And we must remember..........the Elecraft K3S is amateur radio equipment. If you expect better, then I'd say take the cost of your K3 or K3S and multiply it by a factor of 10X and that's what you'll likely have to spend to get into the real world of frequency measurements. And in addition to the two events each year for the ARRL FMT, what does one do the other 363 days? ? That degree of precision is really not needed for day in and day out operation. ? Most ham transceivers are likely to have errors of greater than 1 Hz. anyway. ? Just don't believe what the digital display indicates unless you have gone through a very recent calibration.? I usually check and adjust mine about once per month, on one of those days I'm bored, the bands are dead and it is raining outside.??? As to what others say regarding frequency, I take those comments for no more than a grain of salt. It is ham radio, enjoy it. 73 Bob, K4TAX From kstover at ac0h.net Tue May 7 17:26:03 2019 From: kstover at ac0h.net (kstover at ac0h.net) Date: Tue, 7 May 2019 16:26:03 -0500 Subject: [Elecraft] Prospective K4 In-Reply-To: <83ea7234-e57a-4f98-af0c-d45aa633ba28@subich.com> References: <328523bb-764e-7c51-204d-008fc34b0f1a@inkbox.net> <0811f46c-2d69-40a5-8feb-875153bdecec.maildroid@localhost> <810500DF-DE94-47DF-8B7A-115ABE168A9E@charter.net> <260328f0-5354-b05d-3880-8b8550ed230c@gmail.com> <294f7b3b-4ea9-1668-7dfe-3466ea39a03a@kn5l.net> <83ea7234-e57a-4f98-af0c-d45aa633ba28@subich.com> Message-ID: <000a01d5051b$7e4e6360$7aeb2a20$@ac0h.net> Amen.

Change the XV2 IF parameter to 144. The XV2 ADR parameter gives the band decode that will be sent when that transverter is selected, and can be used to activate your 1296 transverter if you decode the band data correctly. 73, Don W3FPR On 5/9/2019 10:13 AM, Paul Gacek via Elecraft wrote: > I have had the KX3/2m and SG Labs successfully working by simply selecting the KX3 2m band (i.e the KX3 VFO displays 144.200Mhz etc) and driving the SGLabs box with 144Mhz signals. > > ?and if interested in prior UK adventure with my KX3/SGLabs box check out https://w6png.wordpress.com/2018/10/14/black-is-black > > As a SOTA guy mental arithmetic on a peak can be faulty and so I would prefer to configure one of the spare XVn (2-9) for 1296Mhz display/operation. > > I have left the 2m XV1 parameters untouched and set the XV2 parameters as follows; > > XV2 (on) = Yes > XV2 (RF) = 1296 > XV2 (IF) = 50 > XV2 (Pwr) = 3.0 > XV2 (OFS) = 0 > XV2 (Adr) = trn1 > > Unfortunately I am not driving the SG-Lab transverter with these XV2 settings and the band set to XV2 (i.e the one between 144 and 1.8Mhz > > What have I misconfigured? > From w6png at yahoo.com Thu May 9 14:50:59 2019 From: w6png at yahoo.com (Paul Gacek) Date: Thu, 9 May 2019 19:50:59 +0100 Subject: [Elecraft] KX3/2m driving an SG-Labs 1296Mhz transverter configuration question In-Reply-To: <7ffb5655-9111-27ec-20e9-a988a07530b8@embarqmail.com> References: <988A31EA-64D6-4E73-B178-28C3C5AFBE9D@yahoo.com> <7ffb5655-9111-27ec-20e9-a988a07530b8@embarqmail.com> Message-ID: <4A6B944E-82CC-423C-A537-EC9A6D77B590@yahoo.com> Thanks but 144 does not show up as an option when I select XV2 IF.

Message-ID: Hi, Out portable yesterday - KX3 powered by an 8400mahr LiFe battery pack, which was fully charged that morning before I started operations. Antenna was a Buddipole vertical on 7119, SWR1.1, with j, C and L components all zero (ie on the antenna's resonant frequency). KX3 running at 15W out. After an hour of operating (SSB), the KX3 started to wander off frequency by a 1Khz on transmit. A contact noticed this during a QSO. The battery showed 13.1v at the time.

I use my KX3 down to 10 volts an lower without any frequency change. I suspect rather great transitional resistance, especially when transmitting. Are the wires from the accu to the KX3 thick enough? Are the connectors are stable enough (no defective/intermittent contact)? 73/72 de Ingo, DK3RED - Don't forget: the fun is the power! www.qrp4fun.de - dk3red at qrp4fun.de From rmcgraw at blomand.net Fri May 10 09:26:46 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Fri, 10 May 2019 08:26:46 -0500 Subject: [Elecraft] k3-10 & K3S-10 In-Reply-To: References: <000001d506ce$d02c9530$7085bf90$@lazyh.me> Message-ID: I misunderstood the question. 10 watt no. 100 watt yes.

Sometimes the power output goes to the full programmed output and pulls back 1 watt or so. It doesn't happen every time I transmit but quite often and I can't figure what's wrong. Looking forward to find a solution for both of us. 73 Bert VE3NR On 5/10/2019 8:24 PM, Petr, OK1RP/M0SIS wrote: > Hi all, > > so all TX part alignment went ok.

The POWER control line originates at the U2 DAC on the front panel and is applied to Q5 on the RF Board. You should check all components associated with Q5 to be certain of the value and good soldering. Since the POWER signal line is derived digitally from data out of the MCU, it may be that the "problem" is simply one of digital resolution. If the real value is in between 2 DAC steps, the POWER output signal can vary between the two DAC steps causing the situation that you observed. 73, Don W3FPR On 5/10/2019 8:24 PM, Petr, OK1RP/M0SIS wrote: > Hi all, > > so all TX part alignment went ok.

That is difficult to do because the measurement probe can induce and pick up stray coupling at VHF/UHF frequencies. I normally judged the overall performance of the XVseries transverters by injecting a -140 dBm signal (controlled so there is little leakage) with a connected receiver.? I expected the receiver response of that combination to show a 20 dB or greater audio signal above the receiver noise floor. In other words, I used a 'system approach'. If the overall response was not acceptable, in all cases, replacing the PHEMT corrected it. 73, Don W3FPR On 5/12/2019 2:29 PM, Rajiv Dewan wrote: > Thanks Don for your prompt reply. > > I built it a few years ago and I think it worked then.?

I?ve built and owned Elecraft gear since 1999. Still have my KX3 and KX2. I bought a Flex 6600M rig and it was the best radio I?ve owned in years. But Flex messed with the firmware to where if you were in full QSK mode and used the internal ATU a loud relay would start clicking when sending CW characters, messing with the normally quiet QSK changeover from RX to TX. The reason given for this firmware change was that when the ATU was engaged in full QSK mode the receive signals would be 10db down as opposed to zero db loss without the tuner in line. To be honest I never noticed this problem but Flex, in all of their wisdom, made the disruptive change. IMHO this firmware change completely ruined a very FB CW rig. Perhaps the folks at Flex are not as CW-centric as the Elecraft folks. In terms of a K4 I would certainly love to see a beautiful 8? or large front panel display. This is the direction all modern radios are going?.just look at the YaeCommWood offerings plus the Sun MB1 rig. While the P3 and PX3 displays are OK, a full 8? or larger hi-res display is breathtaking and extremely useful. So, why not a K4 with a big hi-res screen? I?m ready for it?make it happen!! 73, Joe W2KJ I QRP, therefore I aim > On May 5, 2019, at 11:16 AM, Rose wrote: > > Bert, > > Then why not just purchase the Flex? > > 73 ! > > K0PP > > On Sun, May 5, 2019, 09:11 Bert Craig wrote: > >> I'm in the comparison stage of planning my next, and likely final, HF >> rig purchase.

Maybe corporate feels that FT8 is just an evanescent craze that will soon go away, thus no need for narrower notches. But hey! A boy can dream.

That's the width of only 2 FT-8 signals and the depth of the notch is about 40 dB.? Certainly will take out 1 or 2 signals and not affect others in the 2.7 kHz BW of the normal FT-8 receiver bandwidth. As to the bleeding ears, turn the volume down.?? I don't find it necessary to hear any FT-8 data.?? Also, correct attention to AGC parameters does a lot to deal with strong signals in the midst of weaker signals.?? Also the use of ATTN and RF Gain reduction is a big advantage, specially on 160M - 40M and to some extent on 20M.

The design of the K3 notch filter predates most digital modes currently used (excluding RTTY). Earlier digital modes, were wider. It may be possible to change the behavior. 2). The use of legal limit or not isn?t the issue; as it may be needed to make the DESIRED contact, typically often required on the lower bands. Your ability to hear such a strong signal has many factors, including band conditions and proximity. 3). I defy anyone to determine without going to the other station or asking, if the ?offending? station is using a 10 dB amp or 10 dB gain antenna. Gain=gain, the means isn?t important. Use what is needed to complete the contact. Without an amp, I would not have been able to work enough stations this past winter, for a 160 M DXCC (inverted L, 600 watts, 108 worked). It would have been simpler has most of those I worked, also had more signal. Full legal limit is very common there. I don?t listen to the digital modes but enjoy the quiet, volume down, ears safe (too late now). I also run with AGC off, which doesn?t stop the audio system from using its AGC and causing blocking. However, FT4 and FT8 are very adept at hearing around the very strong, to hear the very weak.

I don't find it necessary to hear any FT-8 data. Also, correct attention to AGC parameters does a lot to deal with strong signals in the midst of weaker signals.

Not quite -- there's a lot of phase shift associated with the amplitude response change of the notch, so it degrades docoding of signals for some unknown bandwidth on both sides of the notch. K1JT warns against using any filtering ahead of the WSJT-X decoders for this reason. 73, Jim K9YC From jim at audiosystemsgroup.com Sun May 12 20:02:17 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 12 May 2019 17:02:17 -0700 Subject: [Elecraft] K3s Notch Filter In-Reply-To: <02223B65-852E-460F-BBD2-A632EBE4F26B@gmail.com> References: <999F9D86-D5F7-4F08-9F1B-21992E027FD9@comcast.net> <20190512222724.C65DD149B209@mailman.qth.net> <0ee5ff4b-6d50-adf4-62cd-87418f419f45@blomand.net> <02223B65-852E-460F-BBD2-A632EBE4F26B@gmail.com> Message-ID: On 5/12/2019 4:17 PM, Rick Bates (WA6NHC) wrote: > The use of legal limit or not isn?t the issue; as it may be needed to make the DESIRED contact, typically often required on the lower bands. Your ability to hear such a strong signal has many factors, including band conditions and proximity. Right. As to decoding weak stations around much, much stronger ones -- I face that often on 160M and 6M, which is 99.9% of my FT8 activity. My solution is to set the input gain to the decoder so that the strongest signals don't cause the A/D to clip, but raise the level of the weaker stations so they are above the bottom of the A/D. The indicated input level is then about 70 dB. Clipping is indicated by the green vertical bar turning red.? And I run with slow AGC. 73, Jim K9YC From KD7RJ at frontier.com Sun May 12 20:17:06 2019 From: KD7RJ at frontier.com (Ron Gould) Date: Sun, 12 May 2019 19:17:06 -0500 Subject: [Elecraft] KX2 not transmitting Message-ID: <1040FAB6-00B3-4C0B-ACF6-95AB245AF0BF@frontier.com> Selecting CW or SSB the transmitter light does not indicate transmission nor does it transmit when microphone or paddle attempts send dits or das.

Probably not, but both the notch filter and AGC are the wrong tools for the job. The WSJT-X decoder has huge dynamic range (16-bit 48000 samples/sec input decimated to 12000 samples/sec, so over 90 dB), so it's best to use the RX as a dumb converter and let the decoder deal with it. It's the right tool for the job. This means keeping the bandwidth of the RX at least as wide as the band displayed on the waterfall and avoiding the use of anything in the K3 that might improve the signal for aural CW/SSB reception such as notch filtering, equalisation, noise blanking and noise reduction. AGC should be avoided because the level of every FT8 signal in the passband will be modulated by fading on the strongest signal, which makes the decoder's job harder. The AGC recovery time may also cause the loss of more symbols than necessary when there's impulsive interference such as lightning static. The trick is to set the gain manually through the chain, from the RF gain knob on the RX right through to the waterfall settings, so that levels are matched and no one stage in the chain is either clipping strong signals or pushing weak ones below the noise floor. If you ears are still bleeding then turn the AF gain down. If the WSJT-X 'thermometer' is in the red turn the RF gain down. If the waterfall isn't showing both the weakest and strongest signals properly, adjust the waterfall zero and gain controls accordingly. The "morons" are not running legal limit to cause you trouble. We're doing it (for example) because the loss on the 160m path between G and JA is so high that we need legal limit to get even a faintly detectable signal at the other end. 73, Richard G4DYA From dean.k2ww at gmail.com Mon May 13 08:37:54 2019 From: dean.k2ww at gmail.com (Dean L) Date: Mon, 13 May 2019 08:37:54 -0400 Subject: [Elecraft] FS--KX3 Message-ID: I have for sale my KX3 in very decent shape, includes: KXat3-auto tuner Kxfl3-roofing filters Kxbc3- Batt charger/clock Protective Handles Can deliver to hamvention, ior will ship USPS f not sold before then.

I will offer an alternative view on use of the NB. Yesterday, AG6EE was in a rare grid in northern NV on 6M, and there was VERY strong impulse noise coming from his direction. Without the NB, WSJT-X could not decode him. WITH the NB, it did, and I made the QSO. I would NOT recommend general use of the NB, because it generates IMD that results in multiple decodes of the same signal, but there are exceptions to every rule. :) > AGC should be avoided because the level of every FT8 signal in the > passband will be modulated by fading on the strongest signal, which > makes the decoder's job harder. I find that this is not a problem with AGC-S, primarily because in my situation, the very strong signals are locals, not subject to QSB. 73, Jim K9YC From rmcgraw at blomand.net Mon May 13 13:45:34 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 13 May 2019 12:45:34 -0500 Subject: [Elecraft] WSJT-X, AGC, Notch, and NB In-Reply-To: <9babcbc6-6c51-d9df-b5e3-d330810ffd19@audiosystemsgroup.com> References: <999F9D86-D5F7-4F08-9F1B-21992E027FD9@comcast.net> <1c932fbb-0361-db4c-33fe-63e80d02c8fb@lamont.me.uk> <9babcbc6-6c51-d9df-b5e3-d330810ffd19@audiosystemsgroup.com> Message-ID: I must agree with Jim on every point.??? The noise blanker does work but only on impulse signals.? It does little to nothing on broad band noise and in fact, as Jim stated,? can be degrading to the decoding of signals if used with broad band noise. And I agree that reducing BW or changing? SHIFT is not an ideal means, but do use 2.7 kHz to 2.8 kHz for better receiver performance.? Just let the software do its job.?? With wider bandwidths as opposed to filtering to lesser bandwidths, with wider BW's there is less impact on the decoding success of the software.?? The software is designed to operate within the normal SSB bandwidth of the spectrum.?? If there are signals higher in frequency or lower in frequency there is nothing wrong with using the "big knob" on the radio to change frequency slightly to receive those signals.?? And again, the software knows what to do when it comes time to transmit. And I find the use of slow AGC is really a must.? The electronics is much better than I am for determining if gain needs to be adjusted.?? Just let the superior electronics and software do the job. 73 Bob, K4TAX On 5/13/2019 12:18 PM, Jim Brown wrote: > On 5/13/2019 2:53 AM, Richard Lamont wrote: >> The WSJT-X decoder has huge dynamic range (16-bit 48000 samples/sec >> input decimated to 12000 samples/sec, so over 90 dB), so it's best to >> use the RX as a dumb converter and let the decoder deal with it.

The AXE1 is quite rugged. It's exactly the same length as the other two parts of the AX1 whip. All three easily fit into our smallest KX2 bag (the CS40) along with the supplied ground radials, a KXPD2 keyer paddle, earbud-mic, logbook, etc. We hope to have the AXE1 available in late summer. 73, Wayne N6KR > I really like this antenna and would love to extend its > capabilities to 40! > 73's Mike AB7RU From mspmail2 at gmail.com Mon May 13 22:08:18 2019 From: mspmail2 at gmail.com (Mike Parkes) Date: Mon, 13 May 2019 19:08:18 -0700 Subject: [Elecraft] AXE1 extender?

What it won't do is turn it back ON. As I understand it, what the two-button method is designed to do is to make sure the radio saves its current state before it shuts down. If you turn it off via the power line, it will lose any information or changes since you last shut it down properly. Theoretically, you could shut it off with a relay on the power, and all that would happen is it would revert to an earlier state that was saved by shutting it off with the two-finger salute. The problem is, as you noticed, with turning it back ON again. Turning off the power to turn it off only loses the current state, and that might be okay for your use case, but I don't know of any way to turn it back ON again by turning the power ON. This is one of the disadvantages of a soft-switch approach. You might be better served by using a radio that CAN be turned on and off from the power line without causing difficulties, if that is a dealbreaker. Unless you can figure out how to bypass the soft-switch by modifying the radio, something I certainly would NOT want to do myself. I'd probably let all the magic smoke out if I tried. 73, Gwen, NG3P On Mon, May 13, 2019 at 10:48 PM Kenneth P Alexander wrote: > I'm considering buying a KX2 for remote operation; CW and digital.

Something to seriously consider is the robustness of the remote connection, Given that you?ll be depending upon internet that spans the globe, the ham site will be remote and presumably not occupied for the majority of the year, and where a software failure or PC hiccup can destroy your ability to operate, please think about establishing a system that can be managed. I?m also struck that given all of the effort to put a remote ham site in service, you?re thinking of a (very good) QRP transceiver where QRP adds to the complexity of making actual contacts. I operate remotely 85% of the time where my station is in SE Georgia and I?m in Texas or New England. When something goes wrong at the ham site, it will be typically be 5-6 weeks before I?ll be back at the site. In your case, I suspect that you will not be able to visit your ham site as frequently. If your ?host? is not a ham, it may be difficult for that individual to help resolve any problems if he/she is not familiar with your equipment. So here are some suggestions/comments for your consideration: 1. Use a transceiver that allows for remote power on/off as a feature. 2. Avoid having to depend upon a PC at the remote site. PCs can have hardware failures. PCs can fail to reboot. A UPS may help mitigate power surges and short time power loss, but if the site is remote what are the chances of extended power outage? True, PCs can be configured for ?boot on power-up? but what if the PC fails to reboot due to loss of power or while doing a Windows update (which Microsoft continues to make it more difficult to prevent from happening)? If you?re depending upon a PC at the remote site to make things work, you?re also creating a single point failure. Do I use a PC in the shack? Yes, but it is not controlling critical systems so that if the PC is offline I can still operate. I can control it remotely with VNC Viewer. 3. What level of internet is available at the remote site? If it is relatively slow DSL (in Georgia I had to initially contend with 6 Mbps downlink/768 Kbps uplink until two years ago), you?ll need to use something that takes relatively little bandwidth to control the radio and feed audio both directions. Given the distances between Thailand and Canada, you may also have to contend with internet latency. 4. Will you need to control other devices such as an amplifier or rotor? If so, look for devices that provide a web-based interface so that you can avoid a PC in the shack and simply use a browser on the PC, tablet or smartphone in Thailand. 5. Think about remote access. Will you need to be able to remotely configure and/or activate/deactivate your equipment from Thailand? 6. Presumably you will be traveling to Canada to install your remote site. Be prepared to spend a considerable amount of time necessary to not only do the install but to extensively test your system through a remote connection including ?disaster recovery.? You don?t want to end up back in Thailand and then realize that a connection was missed, something did not reboot/come back online, something was wired backwards, etc. So with these considerations in mind, here is what I use for my remote station that meets the above criteria. I am not suggesting that my ?solution? is necessarily applicable to your situation or budget. Rather, I?m suggesting that taking the time to think through what it will take to establish a reliable remote system that meets your needs is critical to your enjoyment and that selecting the transceiver is but the first step in designing your system. A. The transceiver at the ham shack is a K3. This transceiver is designed for remote operation. I use the K3/IO-mini which mimics the front panel of the K3. I use the Remote Rig RRC-1258MKII "pair? for interfacing the two devices with one unit at the ham shack connected to the K3 and the other unit connected to the K3/IO-mini where I am. The beauty of this approach is that 1) I have complete control of the K3 operating it as a K3, 2) I can turn on/off the K3 with no problems, and 3) There are a variety of built-in audio Codecs within the remote rig available that allow you to select one based upon the quality of the internet connection. With only 768Kbps upload at the shack, I had no problems with audio quality while controlling the K3 as the remote site was uploading to the internet from other devices for other purposes simultaneously. B. The Remote Rig RC-1216H provides a web interface capable of controlling a variety of amplifiers and rotor controllers. I have one to control my KPA500 and one to control a Green Heron rotor. C. I use a Digital Loggers Web Power Switch Pro to remotely turn on/off AC devices. The system can be configured for each AC port (there are 8) to power off, a timer can be configured for a desired interval, and then automatically turn power back on. This allows me to reset my DSL modem, my router, the radio?s power supply, and other devices as needed. Again, equipment can ?hiccup? so being able to restart something as needed is very handy. The Web Pro Power Switch can also be configured to determine if an internet connection is lost and if so, power cycle the modem and router. D. For devices that use 12 VDC, I use a West Mountain Radio R4005i that allows web access to control five ports. This allows me to remotely turn on/off preamps, other radios, etc. E. I setup DDNS and port forwarding within the router at the remote site to be able to access the Remote Rig setup, Digital Logger and other devices. This allows easy connection to access everything in the shack from anywhere. Each device has its own UDP/TCP port identifier so that using a browser makes it possible to access individual devices. F. I will also note that I have a KAT500 tuner which does require a PC connection to be able to control remotely. However, I installed a Lantronics Serial-to-Ethernet converter that allows a PC where I am to access the KAT500 directly without having to use the PC in the shack. Hopefully, Remote Rig will someday modify the RC-1216H to be able to control the KAT500 through a web interface. My system has also evolved considerably since 2014 when I purchased my K3/KPA500/KAT500 I?ve added web-based devices to control my system. I added the Digital Loggers device and the Lantronics serial interface. I added an Antenna Genius that can be remotely accessed as well as configured for automatic band changes. I also use a Flex given that SmartLink 2.x was introduced in 2017 that made it possible to remotely connect to my Flex-6700 through SmartSDR, SmartSDR for iOS, DogParkSDR, and Maestro without a PC in the shack and my DSL in Georgia now has 2 Mpbs upload speed that can support the wider bandwidth requirements of Flex products. Bottom line is that it takes a considerable amount of time and effort (and money) to install a robust and reliable remote site. Reliability and ability to manage your equipment remotely are critical for sustained performance. If the system is offline and can?t be put back into service within a ?reasonable period? (whatever that means to you), then you?ve gained nothing. Remote operation allows me to operate HF anytime as there are restrictions to installing such a system where I am in Texas and New England. Given the benefits that it has provided me, I believe it has been worth the investment in dollars and sweat equity.

OTOH, the K3 and K3S do have provision for remote power on via the Power On pin in the ACC connector. The two button power on/off is present so the KX2 and KX3 cannot accidentally be turned on while bouncing around in a backpack, etc. Even if power is removed, the 2 button keypress is required to power it back on. If there is a human available at the remote location to power the KX2 on, then all should be OK. After power on, the KX2 can be controlled via CAT commands. 73, Don W3FPR On 5/14/2019 11:01 AM, Bob McGraw K4TAX wrote: > Consider adding a local phone and a touchtone decoder to do some basic functions, on off, resets, and etc. More reliable than the internet and it makes the station "legal" having a secondary means of control. > > Bob, K4TAX > From kb3ils at comcast.net Mon May 13 21:17:21 2019 From: kb3ils at comcast.net (Keith Thomas) Date: Mon, 13 May 2019 21:17:21 -0400 (EDT) Subject: [Elecraft] AXE1 extender?

A AX1 was waiting here for me last week when I returned from a business trip. I really wasn't sure what to expect but have a goal of doing more outside operating and antenna setup is always a deciding factor. If you only have a short time to operate, I don't want to spend it all playing with the antenna - and I have done that in the past as I rush along and tangle a pull line or the antenna in a tree. I will keep my wire antennas for sure - but want to get a little collection of tried and tested options for antennas that I can just take out and operate. Friday evening I put it together and set it near the window and connected the KX3 at 15W. I am never one of those "got it on the first call people" but in this case I got Maderia Island. with one call. 20M was closing up shop for the night so that was about all I got. It has been raining here in SE PA non-stop especially on weekends. It dried out a bit finally on Saturday so after cutting the grass instead of operating, I took a camera tripod and put it in the front yard and setup the AX1. It worked great just sitting on a bench nearby with my KX3. Worked a bunch of stations in the AR QSO party on both CW and SSB. Worked some special event stations and one Ecuador station on CW at 15W. I have the tripod adapter as I want the antenna away from me a bit. It works well but the 2 camera tripods I used (one with long extension legs and one with 3 little legs just to hold camera at table level) did not accommodate the adapter real well. When I put it on there, it made the BNC connection tight against the tripod head - but it worked. In the next few weeks I am headed out to central PA for a fly fishing trip and will take the AX1 in case I get a few minutes to operate. The most likely time is in the evening - which is where my interest in 40M and the AEXI comes in....... 73 de Keith KB3ILS > On May 13, 2019 at 8:55 PM Wayne Burdick wrote: > > > Hi Mike, > > > There was some discussion here about a possible extender add-on for the AX1 > > antenna to allow operation on 40 meters, called the AXE1.

The Elecraft K3/RRC-1258MKII package recognizes when a connection is lost and will not command the K3 to transmit once connectivity is lost. The Flex configurations I use also recognize when external control is lost. Given that these radio manufacturers provide products with ?positive control? for remote operating and the manufacturers don?t provide any instructions on the need for ?secondary means of control?, my presumption is that using these products does not require a telco backup to legally use their products. As an example of how well the Elecraft/RRC-1258MKII approach works: I was in Texas and tried to turn on the K3. No joy. The LCD screen of the K3/IO-Mini had an error message indicating that PTT was on as the radio was being powered up and would not complete the connection process to prevent inadvertent transmission. When I got to Georgia I tried to power up the K3 and saw the same error message on the K3 and it wouldn?t fully ?boot? (e.g. no receiver). I subsequently discovered that somehow the external PTT switch assembly (which has a momentary PTT as well as separate lockable on position) at the ham shack was somehow left in the ?locked on? condition. Removed the PTT lock and the K3 booted normally and subsequent test with the K3/IO-Mini confirmed that it was working as well. Nice. That said. presumably the key control is the ability to prevent the transmitter from operating. One way to do this would be to turn off the 12VDC feeding the transceiver. So the approach I use is a R4005i for internet access that feeds 12 VDC output to the radio so that it adds a second means of powering down the transceiver (the first being the radio?s remote on/off connection.) The R4005i output port would be ?on? to provide 12 VDC to power the transceiver. In my case, I use a separate R4005i to provide power to each transceiver. This is particularly helpful with the Flex because I can force a master reboot by removing power to the transceiver in addition to controlling through remote on/off via a relay. True, I?m using internet as the only conduit into the shack, but I do have the ability to inhibit transmitter operation through multiple means. I always turn off the radios when not in use as the turning off the K3/IO-mini turns off the K3 as well . For the Flex I can access the R4005i to shut down Remote on/off as well as do master shutdown as a matter of course. Given that the shack is in SE Georgia where thunderstorms are prevalent , I alway power down when not in use as well as isolate the antenna connection through use of a Paradan Antenna Disconnect Device for each transceiver that disconnects the coax when power is removed from the transceiver. 73, Barry WD4ASW > > Bob, K4TAX > > > Sent from my iPhone > From w6png at yahoo.com Tue May 14 13:31:55 2019 From: w6png at yahoo.com (Paul Gacek) Date: Tue, 14 May 2019 18:31:55 +0100 Subject: [Elecraft] KX3/2m driving an SG-Labs 1296Mhz transverter configuration question In-Reply-To: <988A31EA-64D6-4E73-B178-28C3C5AFBE9D@yahoo.com> References: <988A31EA-64D6-4E73-B178-28C3C5AFBE9D@yahoo.com> Message-ID: Just to close this out it turns out that the incorrect setting I had was XV2(Adr) = trn1.

In WSJTX Configuration (F2) Radio tab - I set Rig to "None". This turns off CAT control. Then I set PTT to RTS and the COM Port to the one that controls the RigBlaster that is connected to the K2. Lo and behold, the rig is recognized and operation is as expected. Sure, there are no CAT control bells-and-whistles, but the program works KISS.

CAL OPF is not difficult, but does require a signal of known frequency on each band - it is just an adjustment of the displayed frequency. 73, Don W3FPR On 5/13/2019 11:45 AM, Petr, OK1RP/M0SIS wrote: > Hi Don, > > perfect. many thanks for few hints. > > i will do it step by step. > At first I will check physicaly the parts and soldering around the Q5. > Then after I will try to measure the POWER voltage line (R10) for its > stability. > If needed i can replace both the Q5 and D18. > > the only I am worrying a bit about the factory reset if MCU/DAC sampling > issue > as I am not sure what should be re-aligned then after.

Of course PSK31 would be even easier I set the timeout on the KX3 fairly low, so that if something goes wrong the KX3 will automatically shutdown and can be restarted.

So, the suspects are likely D16 & D17. Fortunately, the last time I replaced them I put in a couple of pins from a machined pin socket, so it should be an easy job. I?ve had to replace U6 before as well. I think I have a socket there, too. > On May 4, 2019, at 12:11 AM, Don Wilhelm wrote: > > Bill, > > Set the power at 50 watts and do a TUNE. > Is the output power at 20 to 25 watts?

If that does not fix things, there is likely another problem in the KPA100 wattmeter, likely KPA100 U6 - but get back with the information before replacing it, there are more tests to verify or deny that possibility. > > 73, > Don W3FPR > > On 5/3/2019 10:25 PM, Bill Coleman wrote: >> I?ve recently seem a problem with my K2/100.

They are out of my price range. If I had even half the price of one of those radios going spare I'd consider putting it towards a spectrum analzyer.

Currently building my first Elecraft product, a K2. Got to the encoder assembly and tripped over a bit of a problem. The encoder would not sit flat in the hole in the front panel as the hole is actually only very slightly smaller than the encoder's shaft. I've seen another post mentioning this and reaming out the panel as a solution which was a no for me as it firstly wrecks the nice paint job and secondly makes the knob poke out too far. I sat for a bit and thought and then dug through the junk box and found a ~1.8mm thick M10 washer (10.05mm internal diameter). I used a cheap Noga deburring tool to widen this out to 10.4mm. This now sits over the metal sleeve on the encoder (not on the plastic body - never do this!) and allows it to sit flat in the front panel without rocking and be tightened down without damage. The encoder board does not foul the control board either. Cruddy MS Paint cross section: https://m0xte.uk/pub/k2-encoder-mount.png Hope someone finds this useful.

I'm glad that Elecraft maintains its position at the bleeding edge of amateur radio design and implementation [as I'm sure the K4 will demonstrate]. It's just that I'm still partial to the K2, and for me the K3/s is just a supercharged K2. I was satisfied with my MG-TD, and while appreciating the Porsche Spider, I never pined away for one.

With that done, the first shoulder of the encoder at the base of the threaded section will fit flat against the metalwork. No need for any additional hardware or washer. Of course, if you ream out the front panel hold enough so the shoulder beneath the threads can pass through, you will have to add a washer of the type you are describing. In any case, you must flush trim the leads on the encoder board and the back of the Control Board which might contact the encoder board. If that is not done "strange happenings" can occur. I have done this many times for my customers, and have corrected many where the customer did not understand and did it incorrectly. 73, Don W3FPR On 5/16/2019 7:45 PM, Chris Smith wrote: > Hi all, > > First post so hello. > > Currently building my first Elecraft product, a K2. Got to the encoder assembly and tripped over a bit of a problem. The encoder would not sit flat in the hole in the front panel as the hole is actually only very slightly smaller than the encoder's shaft. I've seen another post mentioning this and reaming out the panel as a solution which was a no for me as it firstly wrecks the nice paint job and secondly makes the knob poke out too far. > > I sat for a bit and thought and then dug through the junk box and found a ~1.8mm thick M10 washer (10.05mm internal diameter). I used a cheap Noga deburring tool to widen this out to 10.4mm. This now sits over the metal sleeve on the encoder (not on the plastic body - never do this!) and allows it to sit flat in the front panel without rocking and be tightened down without damage. The encoder board does not foul the control board either. > > Cruddy MS Paint cross section: https://m0xte.uk/pub/k2-encoder-mount.png > > Hope someone finds this useful. > From lladerman at earthlink.net Thu May 16 22:45:25 2019 From: lladerman at earthlink.net (W0FK) Date: Thu, 16 May 2019 19:45:25 -0700 (MST) Subject: [Elecraft] K4 price?

Well, the K2 is still available. I think it will be quite beneficial to Elecraft to offer the classic K3 architecture and now the K4 architecture. Until sales drop to zero or some critical component becomes no longer available, I expect the K3S to remain in the line up.

Although I've suspected for several years that this project was underway, I never attempt to compromise those friends by probing for info. I've long had friends and colleagues in sensitive gigs, and that's always been my practice. If someone wants to volunteer info, I'll listen. I'm quite happy with my early s/n K3s with dual RX and upgraded synth and preamp. I'm in no hurry to buy a K4. 73, Jim K9YC From jim at audiosystemsgroup.com Fri May 17 03:36:23 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 17 May 2019 00:36:23 -0700 Subject: [Elecraft] K4 In-Reply-To: References: <19B1349EE9904C8EB18EC2DB797DDFD5@LeroyPC> <9ec64341-adf9-4ec9-c016-464 9aab0a790@triconet.org> <13a715de-4f7f-d524-fd90-9ce81faea4b0@ve3syb.ca> <9814bd88-f0cb-d92e-9f6e-b77426f8b55c@audiosystemsgroup.com> Message-ID: <017ee923-017a-5eba-25a2-c573632fd017@audiosystemsgroup.com> On 5/16/2019 11:02 PM, Wes wrote: > My K3S has only one receiver.

However, RO has presented its own peculiar set of adversities. In my case, the control location (CL) is at my home, and the radio location (RL) is at the remote site, and the sites are separated by a 20-25 mile non-line-of-sight path. The internet connection I am using between CL and RL is managed by REMOTERIG 1258 equipments at both ends of the path. The ISPs involved at the CL are Cincinnati Bell Telephone (mainly fiberoptic) and SPECTRUM (mainly cable), and SPECTRUM-only at the RL. Both ISPs seem to have the same problem: remote ops go well for random lengths of time, and then the connection suddenly "drops out". The evolving workaround is, after, say, calling CQ, and tuning in an answer properly, and turning the control off and on to store the proper tuning parameters in case of a dropout, to warn my (mostly CW) contacts of the possibity of a dropout, and, if one occurs, please QRX while I "reset the system". "Resetting the system" consists of turning off the control (K3 or the K3/0 MINI at the CL), waiting some few seconds until the control "beeps", then turning the control back on to see if the system has reset (resumed comms); if it hasn't reset, turning the control off again (and waiting for the beep) and then back on and repeating until the system resumes comms. Lately, it has been taking from 2 to 6 repeats to get the system operating after a dropout. I'm gonna wear out the power switch. Resetting the REMOTERIGs does not appear to cause, help, or otherwise affect the reset process. There are other issues, such as whether REMOTERIG implements all or a select subset of the K3 functions. They can wait. ----- Brgds, Dave, N3HE Cincinnati OH -- Sent from: http://elecraft.365791.n2.nabble.com/ From KY5G at montac.com Fri May 17 06:36:18 2019 From: KY5G at montac.com (Clay Autery) Date: Fri, 17 May 2019 05:36:18 -0500 Subject: [Elecraft] K4 In-Reply-To: <1444506055.1077939.1558087295055@mail.yahoo.com> References: <1444506055.1077939.1558087295055.ref@mail.yahoo.com> <1444506055.1077939.1558087295055@mail.yahoo.com> Message-ID: <122ab253-4eee-6282-1b71-2b659756acc0@montac.com> LMAO!!!!?

That was true for the K3 and KX3 - yes it is unlike the experience with the K2, K1 and KX1 which were not available as factory asssembled (kit only), but they held a Field Test with a number of builders which resulted in many changes to the assembly manual. That is not the same as the situation today. The kit version will available only after a substantial number of factory assembled units have shipped. My wild guess it will be 2 to 3 months later than the ship of the first factory assembled units. 73, Don W3FPR On 5/17/2019 9:41 AM, Dauer, Edward wrote: > Here?s the vexing problem.

If you have one it is still no guarantee that you will do great things (I haven't--not like Wes has!!). Nonetheless, it is a tool, and a very good one if used properly. Some may question the cost benefit, and that is a very valid point. However, cost/benefit doesn't seem to enter into the equation much of the time, since if it did, we wouldn't see so many exotic rigs on people's desks!!! My K3 has two receivers, as did the Orion II that preceded it. However, I didn't get the 2nd RX straight away on my K3. It didn't take long, though, as I had gotten spoiled by the Orion II's 2nd RX and what I could do with it. Actually I had a "taste" of what a 2nd RX could do with some of my older Ten-Tec gear (Omni A, series B, and a Corsair). Both had outboard 2nd VFO accessories, and with either you could monitor a 2nd frequency while transmitting on another. Not quite the same as having a 2nd RX, but close enough, particularly at that stage of rig development. Maybe I misread things, but with the K4 it looks like a 2nd RX is standard, not an accessory. The "P3" is built in as well. The only accessory I noted that would be mandatory in my case is the ATU, the KAT4. So, all together it seems that a K4 can actually be cheaper than a well accessorized K3S! Now, that is an interesting fact. I say that because, in the past, Elecraft has announced new rigs, but then taken several (many!) months to actually get production going. Since the K4 is supposedly a big advancement, and a well equipped one is actually cheaper than the predecessor K3S, it would seem that orders for the K3S are about to dry up--big time!!! I don't see Elecraft sitting on their hands for several months with no rig orders (can the KPA1500 orders sustain things in Watsonville?), so my guess is that the time frame between announcement and production is going to be much shorter than usual. Well, that's my guess anyway. Well, this is strictly a spectator sport for me. I have no plans to replace my K3 anytime soon. Not that I'm not impressed with new developments, but I'm just too far down the road to jump all over new stuff like I used to. I am looking forward to seeing a K4 in action though! Hi. Somebody nearby please buy one!!!! Cheers, Dave W7AQK ---------------------------------------------- From: Wes My K3S has only one receiver. The K3 before that had only one receiver.?

To reduce the current draw, increase the power source voltage - 14.5 volts or so will reduce the current. The K3 power control circuit is designed to maintain the requested power output - so more voltage equals less current for the same power. There is a basic current draw for the low level stages in any radio, and that is a major portion of the 3.6 to 4 amps of your current draw at 10 watts. At the 13 watt level you have to add the idling current of the KPA3. Above that 13 watts, you can assume about 50% efficiency for the PA itself. 73, Don W3FPR On 5/17/2019 7:02 AM, TL_Netvision wrote: > Hi all > > > > I am trying to understand power consumption of a 100W K3 (new synth., tuner > off, no 2nd receiver) at various output-power levels. > > > > 1.

On both radios, when I sold them, the TF-SET button didn't say TF-SET anymore... It was blank. I wore the label right off of them pressing that button rapidly over and over and over in split pileups. My K3 has two receivers. I have macros that automatically activate the second receiver and set my TX VFO up 1 or up 5 depending on the mode. The macro also places the second receiver in my left ear and the main VFO in the center of my headset stereo image. I don't hear the popping noise when switching VFO's anymore. I don't worry about remembering to press LOCK on VFO A to save me in case my timing is off when tweaking my TX frequency anymore. I like that. After 10 years of ownership, the K3's REV button still has the label printed on it. I don't expect that label will ever wear off. I really never touch it. Yes my right index finger doesn't get the exercise it used to, but when I need the workout, I go to my club station and use their IC7700. Icom was smart: They put the label UNDER the XFC button. The XFC button is metal. It should take the abuse better than Kenwood's plastic button. Times change. Technology and techniques change with it. Easy is good.

Message-ID: <201905171543.x4HFhU8D019068@mail46c28.carrierzone.com> I suspect not because only one ANT connector is designated VHF/UHF. The dual-conversion K3/K3s has only one DSP so could not do duplex. K4 is direct-conversion so guess its "maybe". One of the three HF/6m ANT would need to be co-opted for Tx. Duplex would really compete with the new IC-9700 for mainstream satellite. 1296 ext transverter would still be required if that band was wanted. 15w is fine for satellite and driving amps if more power is desired. My K3//10 with two Rx works well on 2m-eme with dual-polarity diversity reception using MAP65 and since I do little HF, I'm satisfied with it. I run 144/28, 432/28, 1296/28 transverters with it. Also 3400/144 and 10,368/144 thru an intermediary 144/28. And drive a 100w amp with 1mw on 630m. Like I said before: "only if I win the lottery". Then I would have both K4 and KPA1500 in SO2 with my K3 (haha). And the K4 would have remote capability when I travel away from home (maybe using my iphone). But the K4 is a handsome looking rig!

However when I started there were seperate TX and RX and then there was a Transceiver and I kept my Receiver. Interesting thing that 2nd RX. You put the DX on the RX and you find the guy talking to him with the transceiver and that is called a SLAM DUNK. When the Panadaptor came along we didn't have tune around looking for who DX was working we could SEE IT. I guess you can do the same darn thing reversing and A/Bing and using RIT or TIT or all this nonsense that is totally unnecessary if you have a 2nd RX. I guess what I am driving at here is there are many ways to skin the cat but the easiest way is with a 2nd RX and Panadaptor (pictures being worth 10 thousand words) But I do seriously give credit to those who prefer doing it the harder way. When I was rock bound in the good old days we had to tune up and down the band to find who ever may or may not be calling us. Long CQ's and longer replys to get the qso started. It's so much easier than that now. Same amount of fun still.

Thus the K3 is accurate for my EME and MSK144/FT8 adventures on 2m. Except: I discovered that the XV144 is not synced with anything. The K3 Menu/Config DOES allow for "XV1 OFS", and knob turning, to set in a "Calibration" value. As I do not have the luxury of a bench of accurate test and calibration equipment, I am unable to get the XV1 to get and remain near to accracy. Some friends told me they "Thought" that the XV144, external Transverter, does have the option for an external GPS REFLOCK as the K3 has. Calls to Elecraft revealed, other than friendly people, that there is no way they know to REFLOCK the XV144 .. So List people, figuring I do not want to calibrate every day, how are you users of XV144 keeping your other friends from naggin you every day and every time you call CQ on MSK144 ??

It is true that there is no stock means of syncing the XV144 to an external standard. A few owners have said they were successful with replacing the crystal with a circuit that is synced to an external standard, but I now nothing of that implementation. Perhaps someone who has done it will speak up. How is JP9 jumpered in your XV144. For maximum stability, the jumper should be between pins 4 and 5 (no other jumpers). With that setting, the crystal oven will be powered as long as 12 volts is applied to your XV144 - don't turn the power supply off! Let the oven warm things up for at least a half hour (longer if possible) and then calibrate. It should stay close on frequency. 73, Don W3FPR On 5/17/2019 3:06 PM, Bob KD7YZ wrote: > My K3 has an external "Leo Bodnar" reference [REF * CAL] .

For example when I was calling VP8STI on RTTY (my friend AA7A operating) I tried calling on his last listen frequency but he never seemed to call two stations who were on the same frequency.? So I started looking for a pattern; many guys will tune up (or down) a few Hz or kHz and pick another caller.? This didn't seem to be the case either.? After nearly two hours I finally determined his pattern was.... he didn't have one, he randomly tuned after every Q.? I finally picked a relatively clear frequency and called for awhile until he found me.? I queried him about this later and he confirmed. In either of these cases you really don't need a second RX to figure this out.? Your time is better spent learning sequences and planning when and where to call instead of constantly tuning trying to find the last guy worked. Besides all of the other two-receiver guys who don't know any better are going to be calling on the same frequency too. Wes?

Fred was in Denver at the end of April. I had lunch with him and with another ham friend on the 25th. Fred seemed a bit tired, maybe from having just driven to Denver from his home in Montana; but if he was feeling worse than that he allowed no clue. Because he visited Denver from time to time our getting together was not unusual. Like every other time, conversation with him was invigorating and wide-ranging. And as always he was creative and good humored and interesting and knowledgeable, and genuinely helpful about questions I had been wrestling with and wanted to share. It was for me a delightful occasion. A week or so later he sent a text saying that for medical reasons he would be staying a while longer in Denver, so we should arrange lunch again. Then he entered the hospital. I got a message to Fred via another mutual friend, asking if I could visit him there. The reply came back saying sure. I'll find him in his room among a bunch of tubing. Because I have been, and still am, away from Denver part of this week and through tomorrow, I arranged to visit Sunday, right after I returned. I was going to bring him my KX3, with the binding post adapter and a makeshift stealth antenna he might surreptitiously dangle out the hospital window. I was thinking just last night about talking with him about the new K4 and how quickly there might be yet another KE7X text to help us make the most of it. I did not know the precariousness of his condition and so missed the opportunity to say goodbye. And I missed the chance to do for Fred a small favor, a friendly though trivial thing, that would have been the tiniest fraction of all that he has done for all of us. 73, my friend.

After all, I am a K3 owner serial 443. This radio has been far beyond...great. i can crank out cw QSOs with the very basic K3. The Elecraft experience has been superb and superlative. I loved my K2 too. But, no way i could get a K4 because of the money involved. You see, i do not see rigs as investments. I see them like having a classic car. I just want it. But alas, i am retired. Money is not tight, just earmarked for certain things. K4 is not one. Now, i am flummoxed with a burning facination as to how i can obtain one of these K4 Dream Machines. I had to plant the seed of buying one with my Spouse and she wanted to see how it looked. I showed her the picture and said, "lots of buttons." ? Now, i see a glimmer of hope.

The K4 looks amazing! It will make a lot of people very happy, though I think Elecraft missed a trick not offering an optional 40lb lead base for it. When the K3s came out, I happily purchased a used K3/500 line and upgraded them. They are fantastic! I have used other peoples K3 setups on expeditions for years, and now I have a set for my own. They have already be wonderful. But, dang, I love my K1 and K2 (I have the complete"grey line"). They are the ones I actually want to turn on, and when I do, they are just so delightful to use. For Christmas, I even bought a new set of Bioenno batteries and solar panels just for them. So, yeah, I am very happy that Elecraft keeps pushing forward. It is a business; they must. But I still yearn for a new "hands on ham radio" kit. Maybe a mini-module, or a T2?

Message-ID: <201905180743.x4I7hKI9020468@mail40c28.carrierzone.com> Joe, The link you supplied was not available when I wrote my reply last night (in Alaska 4 hours behind EDST). That label is encouraging. Since the basic K4 model has two direct conversion receivers perhaps one can operate in duplex on a separate antenna. Would depend on separate DSP and audio cktry being present. The announcement refers to addition of VHF/UHF module (which I take to be internal to the radio cabinet unlike current XV series). Ref is likely the same EXREF module added to the synth as in the K3&K3s. Overall freq stability will depend on the TCXO like it is in the current K3/K3s if that is true. I hope provision is made for export of baseband IQ from both Rx. I take both main-IF and sub-IF from my K3 to two LP-Pan locked to the same LO to make use of dual-polarity diversity reception on 2m-eme. Being able to run special sw using IQ input from the K4 would set it apart from most other radios. I am not planning to buy a K4 during the initial roll out. I would wait for the kit version K4D. I have a venerable basic FT-736R that will do 144/432 duplex for the current crop of satellites. Their is work on a geosta 5/10 GHz hamsat that would use digital modulation and require a special transceiver (that is beyond any current satellite radio). Issue with such is finding cheap launch. So quite happy with my upgraded K3 and KX3 (for now). 73, Ed - KL7UW On 2019-05-17 11:43 AM, Edward R Cole wrote: > I suspect not because only one ANT connector is designated VHF/UHF. Look more carefully ... it appears that the XVTR IF IN jack is also marked "V/U ANT 2". Might be enough to allow duplex on 144/432. In addition, the rear panel marking does not designate ANT 4 as VHF/UHF only so perhaps a software upgrade will allow use of other antenna jacks for VHF/UHF. 73, ...

How does all that radio fit into a 10 lb package without compromise? I know Elecraft is known for leaning towards the compact and light weight side of things. For comparison, another new radio just released is almost 27 lbs. A flex 6700 weighs about 13 lbs and there's no faceplate or display on it. Definitely not tied to a desk.

The four internal shield panels are secured together, as well as to the exterior chassis panels. This forms a rigid, lightweight mechanical web that resists flexing, like the frame of an aircraft. In contrast many other transceivers use a heavy, cast interior frame.

I suggest you record your important menu preferences with paper and pencil. The K3 configuration file is for disaster recovery, and not intended to transfer the configuration of one radio to another. In fact, it is saved with a serial number identifier so it can only be used on that one radio. If you have a lot of stored memories, then it may be that the Frequency Memory Editor can be helpful - but I don't know if it will be directly reloadable into the K4. 73, Don W3FPR On 5/18/2019 9:39 AM, Nr4c wrote: > Probably not.

I would instead use the LeoBodnar Mini to replace the local oscillator in the XV144. The process is identical for the XV222. Comments below assume an otherwise properly adjusted and operating XV144, and that you are handy with a soldering iron or a hot air rework station. First, before you start, measure the DC voltage at TP1 on the XV144 with a voltmeter. Write it down. Be gentle unsoldering parts from the PCB. The traces and pads are fragile. Remove U2 - the regulator for the crystal oscillator. Remove the oven if one is installed (no need to create more heat). Remove C15. Repurpose the back panel "Aux" BNC connector and run RG174 (or similar cable) from the connector to the vicinity of C15. Connect the coax center conductor to one end of a small 1000 pF disc ceramic capacitor (value not critical) - short leads! The other end of the 1000 pF capacitor goes into the now empty hole previously occupied by C15 that is closest to Q2 with minimum lead length. Ground the coax at both ends. Done. The other oscillator components can remain in place. Set the LB Mini to 116000000 Hz and the output drive to "8 mA". Connect the LB Mini output to the "Aux" connector. Check the DC voltage level at TP1. If the voltage is the same or higher than the original reading, you are done.? If it is less than before, increase the LB Mini output to the "16 mA" setting. Measure the DC voltage level at TP1 again. Repeat if necessary. This step makes sure you have sufficient drive level to the mixer. My XV transverters are in close proximity to a computer and router, plus several (now shielded) ethernet cables, USB cables and a couple of serial cables. There were many weak birdies observed when tuning across the band. Lots of ferrites helped a little. There are internet articles by Jim, K9YC who discusses why the birdies appear (see his comments and drawings about the "Pin 1" problem), and Bruce, NT4RT, who shows what he did to (among other things) improve the grounding on his XV432. Many of his comments are applicable to the XV144. Adding in the LB Mini may increase the number of birdies present in the receiver output unless additional steps are taken. It may also help reduce birdies to run the LB Mini off of a linear lab power supply at 4.5 volts (cut off the computer side connector of a USB cable, use the +5 and ground wires in the cable to connect to the supply).

It is true that there is no stock means of syncing the XV144 to an external standard. A few owners have said they were successful with replacing the crystal with a circuit that is synced to an external standard, but I now nothing of that implementation.? Perhaps someone who has done it will speak up. How is JP9 jumpered in your XV144.? For maximum stability, the jumper should be between pins 4 and 5 (no other jumpers).? With that setting, the crystal oven will be powered as long as 12 volts is applied to your XV144 - don't turn the power supply off!? Let the oven warm things up for at least a half hour (longer if possible) and then calibrate.? It should stay close on frequency. 73, Don W3FPR On 5/17/2019 3:06 PM, Bob KD7YZ wrote: > My K3 has an external "Leo Bodnar" reference [REF * CAL]? .

That is a useful measure of the dynamic range, as most if not all 16 Bit A/Ds have a lower number of ENOB. Perhaps these should be more prominently advertised as they can be used to compare direct sampling SDRs in a more Apples to Apples fashion. Do you use an FPGA as a Digital Down Converter? If so, prominently advertise that too. Having a high bandwidth I/Q output to USB or Ethernet, and a driver to the standards used by multiple Panadapter and Spectrum Analysis software would also be great. Lastly, the ability to directly sync to a low phase noise 10 MHz reference without frequency jumps would be very useful with said Spectrum Analyis software to be able to use the K4 as a measuring tool. Maybe two modes, sort of follow a crappy 10 MHz source and lock to one that has low enough phase noise to match your radio's performance. 73, Mark W7MLG From rogerp at metalsales.com Sat May 18 14:36:07 2019 From: rogerp at metalsales.com (Roger Palmer) Date: Sat, 18 May 2019 12:36:07 -0600 Subject: [Elecraft] For sale K3S, loaded with loaded P3 Message-ID: If you are interested, please email me and I will email copy of my original invoice from Elecraft for this MINT K3S full options & setup.

I will check it out. Predistortion sure would place the K4 ahead of the majority of the manufacturers (at least the big ones). The tools and the possibilities are available for many years and have been for much longer in the professional sector. However I understand that most of the people don?t care about predistortion - maybe because they don?t really understand the benefit. It probably is a longer process like back in the 70s when car owners were afraid that emission cleaning causes engine problems and low power output. Actually it is funny that we are talking about unwanted emissions and power output here and there................................................(don?t pull my leg - although being German I DON?T appreciate the VW emission case at all!) 73 Roger, DL5RBW -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of ab2tc Sent: Saturday, May 18, 2019 7:36 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K4 and Predistortion Hi Roger, You wrote "With the radios receiverwise reaching the physical limits it now is time to pull up the transmitter side to the state of the art as well.

Hi: I plan to drop my use of Flex radios this year. Until yesterday, I had the new FTdx-101 and a K3S in mind but I'm not in a big rush and was hoping the rumors of a K4 would turn out to be true. Have to admit, I'm surprised by how fast it was announced. So I'm wondering what other people might be thinking about what seems to be two or three great options (Ftdx, K3S, K4). We can do this by direct mail if you like as I don't want to turn this into something it isn't meant to be. I'm just looking for other hams that might be thinking on the same options and maybe want to bounce some ideas around. My goal is a purchase by March 2020 but by the end of the year if I can pull it off. I'll have a 6500, 6700 and Maestro to offset the costs. I have a KX3 I'll be keeping for days in the fresh air. 73, Kev N4TT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From jim at audiosystemsgroup.com Sat May 18 16:56:44 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 18 May 2019 13:56:44 -0700 Subject: [Elecraft] Quandary - Anyone Seriously Considering the Alternativeto the K4?

AND on the air. I worked Wayne when we were operating as N7N from NV during the 7th area QSO party and he answered my CQ. It took a LONG time for Flex radios to be even slightly user-friendly, simply because the designers weren't operators. Their products started taking off when they started listening to top contesters who were beating them up about their terrible user interface. 73, Jim K9YC From w5jr.lists at gmail.com Sat May 18 17:17:35 2019 From: w5jr.lists at gmail.com (Mike - W5JR) Date: Sat, 18 May 2019 17:17:35 -0400 Subject: [Elecraft] K4, Spouse, Retirement, Burning Fascination In-Reply-To: References: <9a5a2ded-eb3a-a39a-4ce1-371263633b46@mail4life.net> Message-ID: You guys need a button class to get more out of your radios....

You might also sell stuff you do not really need around the house, instead of leaving it to your heirs to sort out after you are reassigned to a station in the clouds? You would be surprised how much green you can recover. I sold enough junk last year to finance a new guitar. My wife fully supports any purchase I make with new money outside the investment pool. A new transceiver may be within reach after all - plus you will have that heady sense of self satisfaction the comes from a job well done without dipping into your financial reserves. Work only as much as necessary - I am certainly NOT advocating against retirement! Besides, you may enjoy getting out of the house and mixing with people, and the extra cash should be fun to spend. That is just MY take, anyway ... your mileage may vary.

For sure! Same with current music. No extra charge for the distorted sound. Reminds me of a case some 45 years ago involving broadcast signal quality where I was testifying as the FCC's engineering expert. Those of us with engineering backgrounds knew that what I was referring to as "pre-distortion" was the pre-emphasis / de-emphasis curves commonly used in FM broadcast audio chains. The non-engineer lawyers jumped up and down "what, they are intentionally distorting the station's sound?"

All of which emphasizes the need for using the right words to describe things. The word "distortion" is most commonly used to describe non-linearity, not frequency response. And, BTW, that pre-emphasis/de-emphasis is a Standard, not just "commonly used." You know the Regs far better than I, but I suspect it's there too. As I'm sure you know, it was also common practice to go FAR beyond that, with multi-band dynamics processing and the tricky stuff that Bob Orban was doing. The engineering "rule of thumb" was that if you could see the modulation monitor needle move, you weren't doing enough.:) I did some research on the Orban FM processor, which I published as an AES Paper in 1986. http://k9yc.com/AESPaper-TDS.pdf 73, Jim K9YC From jim at audiosystemsgroup.com Sat May 18 20:16:35 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 18 May 2019 17:16:35 -0700 Subject: [Elecraft] KPA1500 AC Mains wire colours In-Reply-To: <97d7d9c3-bf6d-d9e1-b46f-584aa509304b@montac.com> References: <001d01d50ca4$7b8548c0$728fda40$.ref@arrl.net> <001d01d50ca4$7b8548c0$728fda40$@arrl.net> <35ad835d-7d3b-5ddf-8c8b-cd1665ba766c@ve3syb.ca> <97d7d9c3-bf6d-d9e1-b46f-584aa509304b@montac.com> Message-ID: On 5/18/2019 4:28 PM, Clay Autery wrote: > 230VAC on 3 wires??

Single-phase power normally comes into a building in North America as two phases and a neutral. We connect a 240V load between the two phases, and a 120V load between one phase and a neutral. It's not unusual to feed a sub-panel with both phases, neutral, and ground so that the panel can feed both 120V and 240V loads. The key here is that loads must NEVER be connected between a phase and ground, ALWAYS between phases or between phase and neutral. You probably know that EU runs on 230/240V, wired phase, neutral, and ground. 73, Jim K9YC From P.Hall at curtin.edu.au Sat May 18 21:21:15 2019 From: P.Hall at curtin.edu.au (Peter Hall) Date: Sun, 19 May 2019 01:21:15 +0000 Subject: [Elecraft] KPA1500 AC Mains wire colours In-Reply-To: <5ce01319.1c69fb81.8ecd1.0306@mx.google.com> References: <5ce01319.1c69fb81.8ecd1.0306@mx.google.com> Message-ID: You?re welcome, Doug. I?m glad you have the KPA1500 up and running. Your note, and my recollection of installing my own KPA1500, identify an important omission in the KPA1500 manual. Some other shortcomings of the manual (such as a decent working block diagram) are merely irritating but not including the proper mains connection for a $5000 device shipped internationally is a serious oversight. It?s clear there is not a widespread appreciation of global power standards in this email group (for example) and, rather than having a future user stumble across incorrect or incomplete information, the Elecraft manual needs to have the definitive instructions up-front. I?m not sure how the EU regulations are constructed but I suspect that it?s technically illegal to use the supplied cable in Australia. For Australian users a more immediate consideration on opening the box is that the US cable won?t fit through a standard Australian mains plug cover. You can buy one Clipsal brand plug from a specialised electrical wholesaler which will work, or you can use a heavy duty plug and socket if available. 73, Peter.

Electric clothes driers and stoves, for example, which have light bulbs and sometimes 120 V outlets. (You can imagine what would have happened if 240 V bulbs had been required here.) However, at one time the code did not require separate neutral and ground wires, so the ground was used as the 120 V return. If the ground opens up, your whole stove is suddenly at 120 V. Unfortunately, some of those are still around, and seem to be sort of grandfathered, or just ignored. Hopefully, there's no ham equipment wired that way! 73, Scott K9MA On 5/18/2019 19:16, Jim Brown wrote: > On 5/18/2019 4:28 PM, Clay Autery wrote: >> 230VAC on 3 wires??

I am *not* an official, or even unofficial, Elecraft spokesman and stand willing to be corrected. First, this is going to be another game-changer from Elecraft. The radio will have outstanding performance figures and an interface to die for. The screen is beautiful and functions can be controlled from either buttons or the touch-screen. There is band-stacking on the touch screen, a nit people have complained about on the K3. The radio is full SDR as opposed to the analog front end of the K3. However an option, the K4HD, is a superhet receive function. Like previous Elecraft radios, this can be added later if you think you need it. Preliminary is that it will not be necessary unless you operate in the presence of strong stations (multi-multi). Another option has a second set of band pass filters and ADC module that will allow the two receivers to operate on different bands or antennas (K4D). The radio contains a Linux computer so all this magic does not require an external computer except for logging or audio input. The rig will be addressable locally or over the internet with no additional software. I saw it operated from an iPad and Android is coming. The iPad screen looked exactly like the front panel, including the panadapter. There are multiple USB ports, an Ethernet port, RS232 and an HDMI port so you can project the front panel, or parts of it, to an external monitor. The panadapter looks awesome on the external monitor and you will be able to point and click to QSY the radio. The prices are targets but I got the impression the final will be very close. The cost is less than a fully loaded K3s. The kit version will be cheaper than factory-assembled and ship several months later to allow time to write the assembly manual. Target for the factory version is November. I suspect the K4 will replace the K3 series as K3s sales are sure to suffer because of product age and competition from the K4. I did not hear any talk about sun-setting the K3s when the K4 comes out. I am sure there are many people who will want to buy the basic K3s and upgrade over time (or not) rather than plunk down $4,000 for the K4. What does this do to the value of a K3 or K3s? I expect there will be some coming on the market. Anyone who buys, or retains, a K3 or K3s will still have one of the finest radios ever made. We are at the point where the difference among the top 5 or so on Sherwood's charts is a decibel or two, almost within the margin of error and certainly beyond the ability of the human ear to discern. So, don't panic. The demand for the K3 series will be strong for many years to come.

While the basic K4 is certainly going to be a great radio, it will likely NOT have the strong signal handling characteristics of the K3/K3S. There will still be the likelihood of A/D clipping suffered by virtually all 16-bit SDRs in a high-density RF environment. And although there is a second receiver it appears to be more like a Flex ?slice? .. sharing front end filters with the main receiver. In that regard, the K4D will be a great advantage for dual receivers in general, or for diversity. So by the time you get to the K4HD, you will spend a (I would guess) quite a bit more than a K3S for (perhaps improved by a few dB here and there) strong signal performance in the the most demanding conditions. Lot of tradeoffs to be considered ? for sure. I have far more than the current list price in my existing K3 .. I?ve purchased several new boards for it over the years as various K3 upgrades and the K3S upgrades came out. So the value it has is as a radio, and not a retirement plan. One way or the other, I?ve set up a K4 piggy bank, in anticipation of the kit version next year ? but have no plans at all to part with my K3. It?s too good a radio :-) Grant NQ5T K3 #2091 KX3 #8342 > On May 18, 2019, at 11:09 PM, Buck wrote: > > The following is offered based on my observations and discussions at the Elecraft booth.

So it is important to keep this in mind. To describe the process a little bit better it the introduction of "DeDistortion" would help. While DeEmphasis was done at the receiver end DeDistortion is done at the transmitter end by the amplifier. Just using one part of Distortion (or Emphasis) would really not reflect the true signal that is going into the microphone. As any amplifier stage is adding distortion it is appropriate to call the procedure done in the SDR (the ones that are capable of) PreDistortion. The DeDistortion in the amplifier gives you a much better approximation of a true linear amplification. Just ADDING Predistortion and not adding or better SUBTRACTING the proper amount of Dedistortion sure would make and leave the signal distorted. 3rd order IMD in the range of -60 dB and with careful design even more is possible. Consider this: the best receiver doesn?t help if a lot of average or below average quality signals are around and splattering into your "communication channel". The same is true if someone with a radio that creates a lot of phase noise is next to you - your radio can have a clean oscillator signal with low phase noise but still the other dirty signal will go into the equation. So after it has been acknowledged that high phase noise oscillators are a NO GO these days the next consequent step would be to clean up the transmit signal in terms of intermodulation. If someone tuning a motorcycle or a car he better not only tunes the engine for power but also adapt the brake system the chassis and everything else affected to handle the more power. 73 Roger, DL5RBW -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Sunday, May 19, 2019 2:09 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K4 and Predistortion On 5/18/2019 4:01 PM, Phil Kane wrote: > Those > of us with engineering backgrounds knew that what I was referring to > as "pre-distortion" was the pre-emphasis / de-emphasis curves commonly > used in FM broadcast audio chains. All of which emphasizes the need for using the right words to describe things. The word "distortion" is most commonly used to describe non-linearity, not frequency response.

Current electrical code requires L1, L2, Neutral, and Ground thus 4 wires and not 3. In some ham amplifiers the fan ran off of the split primary to supply 120 volts when the amp was being operated from 240 volts. Thus the ground/neutral was not a current carrying conductor. When I installed the 240 volt service to my operating position, I used 4 conductors of #10, thus I have L1, L2, Neutral and Ground. Of course the neutral and ground are bonded at the breaker panel as required by code.? The ground is a non current carrying conductor, unless an equipment fault occurs. 73 Bob, K4TAX On 5/19/2019 8:04 AM, hawley, charles j jr wrote: > I have in fact seen some home brew amplifiers wired with ground used as the neutral...and it was impossible to talk the owner out of it.

Nearly every radio receiver nowadays is largely an SDR, but the amateur community tends to use the term in a more restricted sense. What I think is meant by Full SDR is what, more correctly, would be described as direct sampling. However, the really key point is that Elecraft's main skills are with analogue electronics. To the extent that the K4 has no analogue front end, it really doesn't benefit from the company's core expertise (although low phase noise clocks may also be one of their skills). Personally, I suspect that there is significant analogue processing before the A/D convertor (the front end) and that is what will give it any edge it has over the competition. A/D convertors are essentially commodity items, to the only real input the Elecraft desginers will have is setting the price point. -- David Woolley Owner K2 06123 On 19/05/2019 04:09, Buck wrote: > The radio is full SDR as opposed to the analog front end of the K3. > However an option, the K4HD, is a superhet receive function.?

I think fldigi uses a few bins either side of the signal to determine the noise in the SNR measurement. When I narrow my K3 IF bandwidth down to just the, say Olivia, bandwidth the SNR number climb up to 30 dB high as the filter cut the noise in the adjacent "noise" bins. If I use a 600-700 Hz filter or wider for a 500 Hz wide Olivia then the SNR measurements stay the same. So I have always thought along the lines of your two emails Joe. Plus long time ago I discovered how I could add FFTs up and a coherent signal would "climb" out of the random noise. So for a signal with considerable time per bin measurement you get that gain as well. So have always thought of the WSJT type negative numbers as bogus. 73, tom w7sua On 5/19/2019 7:18 AM, Joe Subich, W4TV wrote: > On 2019-05-19 9:50 AM, Wes wrote: >> FT8 reports negative SNRs number but we both know those are bogus. > > All of the modes that quote negative SNRs are doing so by using SNR > in a voice (2500 Hz) bandwidth *NOT* SNR in the detector bandwidth > (bandwidth of the final filter whether than be a narrow IF filter, > the "ear-brain" filter or a software [computation] filter). > > If one looks at the SNR thresholds of the various Joe Taylor "slow" > modes, 80% of the "negative" SNR can be attributed entirely to the > difference between the occupied bandwidth and the [excess] measurement > bandwidth.?

Certainly whets the appetite. What the K4 does to the value of used K3 s, however, is highly speculative at this point. For one thing, their second-hand value will vary with how soon, if at all, Elecraft stops producing them, and there is no way even to guess about that without knowing all of the company's internal cost functions as well as sales projections. But speculating is fun to do so I'll add one variable of my own: The K4 may depress the value of whatever rigs many of us now have as backups under our K3. That's what I plan to sell, keeping the K3 as a backup (if I buy a K4.) But I have no idea what those rigs are in other shacks -- in many cases the station may be two K3 s deep now. But for others, which of the other two rigs to sell may depend on how easy it is to swap transceivers on the fly -- i.e., if a K4 fails at a bad time can I just take it off the table, put a K3 in its place, plug in existing connectors without needing adapters or other changes, and continue running QSOs? If so, some used K3 s may not be entering the market quite so fast. So yes, the relative value of used K3 s will very likely decline, inevitably so when there's additional competition. Though even that could depend partly on unpredictable changes in both demand (new hams entering the market) and supply (other radios made by other manufacturers becoming available at nearby price points.) But by how much will their value change relative to what would have happened in a non-K4 world? At this point, that calculation -- including this post -- has so many unknowns it's more in the realm of SWAG than analysis. Which doesn't mean it's not fun to do.

I've noticed that, unless there's QRM, reducing the receiver bandwidth really doesn't help, so the limit factor is the "processing". On the other hand, neither does slowing down below perhaps 15 wpm, as if the processing just can't make the effective bandwidth any lower. Perhaps the real advantage of the JT modes is that they can take advantage of the lower noise bandwidth at very slow speeds, while our brains can't. It would be interesting to compare the performance at 15 wpm. 73, Scott K9MA On 5/19/2019 09:18, Joe Subich, W4TV wrote: > On 2019-05-19 9:50 AM, Wes wrote: >> FT8 reports negative SNRs number but we both know those are bogus. > > All of the modes that quote negative SNRs are doing so by using SNR > in a voice (2500 Hz) bandwidth *NOT* SNR in the detector bandwidth > (bandwidth of the final filter whether than be a narrow IF filter, > the "ear-brain" filter or a software [computation] filter). > > If one looks at the SNR thresholds of the various Joe Taylor "slow" > modes, 80% of the "negative" SNR can be attributed entirely to the > difference between the occupied bandwidth and the [excess] measurement > bandwidth.?

My benefit is the use of the radios and the buyer gets a good price. In one or two hamfests the radios are sold. My wife tells me I am just renting the radios and not to worry the price. I do try maintain a conservation of radio space rule. Buy one, sell one so shelf space stays constant. When we moved from VA to AZ sold 2/3rd of radios and should have sold 3/4ths. In this case I am likely to just shift my upgraded K3 over to a backup/field position if I get a K4. I sold my fully loaded dual receiver K3 using the 75% rule.

The 8-ary FSK of FT-8 may be buried in the ambient noise at my/your/somebody?s QTH. Like LPI communications, knowing where to look in frequency and time allows the decoder to combine noisy samples and recover the original; in the case of FT-8, a 63 bit message. Your receiver does not hear the 63 bits, just the symbols used in statistically recreating the 63 bits. The real issue with sensitivity or receiver NF is making sure that the receiver is a weak contributor to the overall noise power entering the detection process which is generally dominated by ambient noise. Most of the radios in the top Sherwood top 10 are weak contributors in most locations, even in the CCIR-defined quiet rural environments. 73 Bob R ?

As an electrical engineer whose major was "power" (back when it was actually taught) I would agree wholeheartedly. The "2 hot plus neutral" is most often a single phase of a three-phase delta 240V secondary with tapped center as "neutral". It could not be two phases of a wye because the voltage from phase to phase would then be 208V for 120V phase-to-neutral. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From lists at subich.com Sun May 19 14:15:55 2019 From: lists at subich.com (Joe Subich, W4TV) Date: Sun, 19 May 2019 14:15:55 -0400 Subject: [Elecraft] Sensitivity - Was K4 Observations In-Reply-To: References: <2baa6226-9d64-7439-2496-4fdb7db9c852@triconet.org> Message-ID: There is one place that digital modes (like those by Joe Taylor and associates) can improve the decoded SNR beyond simply reducing the detection bandwidth. If the modulation/encoding supports N states but the encoding only uses M of those states, the decoding software can make use of the "sparse constellation" to recognize states that are impacted by noise and select the "closest" valid state. This "coding gain" can improve the overall SNR beyond that provided simply by the "matched" (or optimal) noise bandwidth. However, with all amateur modes (CW to FT8 & FT4) the majority of the SNR improvement over SSB (or AM) is simply due to the use of optimal bandwidth to reduce extraneous noise in the detector bandwidth. Even with SSB, properly tailoring the IF bandwidth will make several dB difference in the detected SNR. For example, a 2 KHz bandwidth (500 - 2500 Hz) can provide significant improvement over a 2.8 KHz bandwidth (200 - 3000 Hz) under noisy conditions. 73, ...

It's clear there is not a widespread appreciation of global power standards in this email group (for example) and, rather than having a future user stumble across incorrect or incomplete information, the Elecraft manual needs to have the definitive instructions up-front. I'm not sure how the EU regulations are constructed but I suspect that it's technically illegal to use the supplied cable in Australia. For Australian users a more immediate consideration on opening the box is that the US cable won't fit through a standard Australian mains plug cover.

There is some "high-tech" coding that adds to the overall sensitivity of the modes. CW eme operators are said to be able to reduce bandwidth "in their heads" to 50-Hz. When I ran CW eme, I found setting my radio to 100 to 200 Hz worked best for me. 50-Hz DSP filter caused too much ringing for me to discern the CW note. Radio sensitivity requirements are mostly set by band noise whose minimum is established by "celestial" (or sky noise). Such noise is commonly characterized as applicable sky noise temperature (in Kevin). Tsky (144-MHz) is thought to be about 250K. At 432 that lowers to 70K and above 1000 MHz approx 10K. Receiver sensitivity is tied to noise figure (which also can be thought of as a temperature (Trx). Overall receiving sensitivity Te = Tsky + Trx + Tant The last factor, Tant mostly refers to how much noise the antenna sees. Earth at 70F is 290K. So if your antenna sidelobes see the earth, that adds to minimum sensitivity one can achieve. A typical 144-MHz eme receiving system noise temp: Te = 250K + 70K + 29K = 349K. Trx=70 is roughly a noise figure of 0.5 dB. As one goes higher in frequency, sky noise is less so one wants the receiver to be less, to improve overall sensitivity. But as one goes lower in frequency sky noise rises a lot. Tsky (50-MHz) is roughly 2000K and Tsky (28-MHz) is 5000K (or more). Making a HF receiver super low noise (low noise figure and thus more sensitive) is severely limited by Tsky (which is in 10,000K to 100,000K). And note that I did not add any factor for human generated noise sources. Te = Tsky + Trx + Tant + Tman-made Sensitivity is measured in signal power which is related to system noise temperature b the formula: Pn = KTB. K is Botlzmanns constant. T is Te derived above. And B is detection bandwidth in Hz. If noise power, Pn is in terms of dBm, then Pn = -198.6 + 10Log(Te) + 10Log(B) SNR = Ps - Pn, where Ps is signal power in dBm. SNR=0 is at the noise level (where Ps = Pn). K3 (with PR6) is spec at Pn = -143 dBm at B=500,000 Hz which is very sensitive. That level would only make a difference on 10m or 6m due to lower sky noise. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From hbjr at optilink.us Sun May 19 18:18:52 2019 From: hbjr at optilink.us (HB) Date: Sun, 19 May 2019 18:18:52 -0400 Subject: [Elecraft] KTCX03-1 high stability reference oscillator In-Reply-To: <6d529d3d-7033-9705-8a25-e9c586b0a432@horizon.co.fk> References: <009301d50e69$48e8d0f0$daba72d0$@optilink.us> <000201d50e84$0b2195c0$2164c140$@N4ST.com> <20190519210234.6A7BF149B58E@mailman.qth.net> <6d529d3d-7033-9705-8a25-e9c586b0a432@horizon.co.fk> Message-ID: More good info!!

There is actually a theory for the case of idealised white noise and no other degradation (both of which are likely to be assumed in the cases previously discussed), that sets a theoretical limit to the error free digital communication rate of channel, based on bandwidth and SNR. This is the Shannon - Hartley theorem, and states that the capacity in bits per second is: bandwidth * log2 (1 + Signal / Noise) Note that this formula still has a positive result even if the signal is only minutely greater than zero. The holy grail of communications coding is to get as close as possible to this without having excessive latency. Maybe a better figure of merit for these, "below the noise" digital systems would be to quote the channel capacity as a percentage of the Shannon limit. I think the system used for 5G mobile phones get very close. One does have to be careful with bits per second, as I understand that FT8 relies on some parts of transmissions carrying less bits than needed to encode the characters in the standard code used, e.g. the number of bits actually represented by a call sign is log2 (number of possible callsigns) and the number encoded in FT8 is log2 (number of active FT8 callsigns). -- David Woolley Owner K2 06123 On 19/05/2019 19:15, Joe Subich, W4TV wrote: > > There is one place that digital modes (like those by Joe Taylor and > associates) can improve the decoded SNR beyond simply reducing the > detection bandwidth.?

But for the safety of all concerned, a clear explanation in the manual of the mains wiring connections in even a couple of the major jurisdictions is essential. My comment re the 230V cable colour code was more directed to ourselves as "importers". Although I don't propose to change mine anytime soon, partly because I already have a lot of Collins gear running off a shack 120V system (including contemporary US cabling and connectors), I suspect that, strictly speaking, I should. 73, Peter.

This ability to purchase direct is important to me. We do not have a dealer in EI and well the UK is leaving the EU. I just as soon purchase direct. I am sure the UK sellers include a UK power cable as do the continental retailiers. Elecraft does a pretty good job. Changing a plug is not problem. Thanks for your help though. 73 Doug EI2CN ________________________________ From: Peter Hall [mailto:P.Hall at curtin.edu.au] Sent: 19 May 2019 01:21 To: turnbull; Ken Winterling Cc: Elecraft Reflector Subject: RE: [Elecraft] KPA1500 AC Mains wire colours You're welcome, Doug. I'm glad you have the KPA1500 up and running. Your note, and my recollection of installing my own KPA1500, identify an important omission in the KPA1500 manual. Some other shortcomings of the manual (such as a decent working block diagram) are merely irritating but not including the proper mains connection for a $5000 device shipped internationally is a serious oversight. It's clear there is not a widespread appreciation of global power standards in this email group (for example) and, rather than having a future user stumble across incorrect or incomplete information, the Elecraft manual needs to have the definitive instructions up-front. I'm not sure how the EU regulations are constructed but I suspect that it's technically illegal to use the supplied cable in Australia. For Australian users a more immediate consideration on opening the box is that the US cable won't fit through a standard Australian mains plug cover. You can buy one Clipsal brand plug from a specialised electrical wholesaler which will work, or you can use a heavy duty plug and socket if available. 73, Peter.

You should not be shipping US power corded equipment to Europe (or I suspect anywhere else outside the USA!) If it was purchased through a local dealer, "they" should have removed the US spec' cord, and replaced it with a EU (or other local) spec' power cord, and also possibly PAT tested it.? (Electrical safety test, relating to insulation and safety ground integrity for all exposed metalwork and connectors.) Do they also comply with the EU "Low Voltage Directive" in regards to Power Factor (Line current distortion) vs the power drawn from the supply I wonder??? If thy just have a transformer/rectifier/capacitor type supply, the answer will be no. If using a bought in SMPS, then maybe, but the SMPS makers data will need to be examined. Transformer Rectifier Capacitor type PSU's for "non industrial" use are largely outlawed over here for such high power applications these days. Regards.

Logically, this means that the RADIO has to be able to send the data stream to form the remote spectrum display. The HDMI output does present an independent from the front panel display of the recievef spectrum data, so there is some hope that this capability exists, at least inside the radio. The remote spectrum display in M1MM Logger + is a really helpful feature, so it would be great to have this without additional wedgeware to make it happen. The fact that there is a Linux core to this radio is encouraging from a feature development perspective.

As an electrical engineer whose major was "power" (back when it was actually taught) I would agree wholeheartedly. The "2 hot plus neutral" is most often a single phase of a three-phase delta 240V secondary with tapped center as "neutral". It could not be two phases of a wye because the voltage from phase to phase would then be 208V for 120V phase-to-neutral. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From pincon at erols.com Mon May 20 07:58:51 2019 From: pincon at erols.com (Charlie T) Date: Mon, 20 May 2019 07:58:51 -0400 Subject: [Elecraft] K4HD In-Reply-To: <29560993-5e72-56e0-b053-6a8c839cbfb4@triconet.org> References: <5ce1a49e.1c69fb81.b772a.3471@mx.google.com> <29560993-5e72-56e0-b053-6a8c839cbfb4@triconet.org> Message-ID: <001901d50f03$679d2c90$36d785b0$@erols.com> That reminds me of a joke that went around in the 40's about a guy named "Franklin Delano (bad word)".

Hi Charlie, The '7610 is an impressive and capable radio. We have one in our shop and have put it on the air. It's a bit of apples/oranges comparison to the K4, though. Since you asked ... here are some K4 characteristics to consider: * Controls -- The K4's UI is quite different, borrowing heavily from the K3, but with an infusion of versatility due to the 7" display. It has the widest available viewing angle and is very bright. (K4 tire-kickers at Dayton were extremely complimentary about the display, which was gratifying after 200 or so iterations on the concept drawing by yours truly.) There are three multifunction knobs (not just one), each mapped to a semantic group, e.g. "XMIT". Their functions adapt to the current operating mode, etc. On the right side of the radio there are three 400-count, ball-bearing drive optical shaft encoders, for VFO A, VFO B, and RIT/XIT offset. No need to multi-task one or two controls. Bottom line: ease of use. If you do get stuck, there's a built-in help system. * Dynamic range -- The K4 is a direct-sampling, dual-receiver radio in its base configuration. But those in high-signal environments can add the dual superhet module to realize a 20 to 25 dB improvement in headroom (blocking dynamic range) over any radio that is direct-sampling only. This is the same delta as, for example, a K3S vs. any other non-superhet on Sherwood's list. * Portability -- The K4 weighs only about 10 pounds, draws only about 2 amps on RX, and can run down to 11 volts. It will try to drag you off to a Field Day site or remote island if not bolted to your desk. ? Remote control -- The K4 comes with remote-control via Ethernet built in. One K4 can controlled by another, or by a tablet or PC. Eric must have demonstrated this 500 times at Dayton and I daresay he's getting good at it. * Modularity -- We segregated the K4's modules in such a way as to facilitate easy update to units in the field if/when new tech becomes available. For example, we could quickly and cost-effectively incorporate a new ADC or DAC. Call it planned non-obsolescence. This the 20th anniversary of the K2, and the 10th anniversary of the K3. Both are still shipping. * Extensibility -- In addition to the HDR module, the user will be able to add a VHF/UHF module, which in turn could morph in the future. This philosophy extends to software as well, given the K4's general-purpose computing module [not Windows]. I like to think of it as our "app engine," limited only by the imagination of our software team and other talented contributors. * External monitor output -- HDMI, not DVI. (To each his own?) * Tuning aid -- The "mini-pan" is one of our favorite features of the K4. When you tap on a signal you don't just get a geometric magnification of the main panadapter's pixels; you get a re-sampled, high-resolution spectral display of as narrow as +/- 1 kHz (varying per mode). This is great for signal auto-spotting and left/right peak search. The mini-pan is per-receiver and can either be turned on automatically or by tapping either S-meter. ? IO -- The K4's IO is a superset of the K3's, meaning it comes with all of the analog and control I/O you might need as well as 4 USB ports, Ethernet, etc. * Antenna sources -- There are up to 3 ATU antenna jacks and up to 5 receive antenna inputs. 73, Wayne N6KR From w1go at icloud.com Mon May 20 21:52:45 2019 From: w1go at icloud.com (W1GO (Joe)) Date: Mon, 20 May 2019 21:52:45 -0400 Subject: [Elecraft] AX1 first contact Message-ID: All, First use of AX1 today in New York?s Adirondack Mountains.

(I believe it is gigabit ethernet..) Usually your network router provides the wifi to connect wirelessly in the house (also including a DCHP iP address server.) Embedding wifi in the radio is problematic as it is a rapidly evolving technology with regular changes in security features, speed etc that are best handled by router sw and hw upgrades. Its unlikely wifi will stay constant over the radio's life. 73, Eric elecraft.com _..._ > On May 20, 2019, at 8:24 PM, Brian Denley wrote: > > Wayne: > When you mention that the K4 has Ethernet (which means cables to me), it must also have WiFi if you can control with tablets, no? > > Brian > KB1VBF > Sent from my iPad > > On May 20, 2019, at 8:39 PM, Wayne Burdick wrote: > >>> Charlie, K3ICH, wrote: >>> >>> OK, So why should I [pejorative deleted] my IC-7610 for a K4? >> >> >> Hi Charlie, >> >> The '7610 is an impressive and capable radio.

But how different can you make a rig with 2 vfo's and touch screen very much different looking.? Take the top and bottomcovers off each rig and see what's inside and hook each up to an antenna and see how they perform in contest condx copying some weeny teeny signal. There is a reason the 7610 is different than a K4 and it's not only the price.? But the 7610 is a decent radio too.? It all depends on what you want sitting on your shackdesk. Whatever tames your pileups.? The K3 is one of the best radios I have used and am glad I decided to buy it in 2009.? I've listened to a lot of radios since 1963.

There are features and performance that far exceed the Icom?s capabilities. Even though, on the surface, they ?look? somewhat alike. My question (only to myself, but rhetorically stated) is should I make the switch? 73, Charlie k3ICH From: David Bunte Sent: Monday, May 20, 2019 2:38 PM To: pincon at erols.com Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] Elecraft IC-7610, Charlie - I have not read EVERYTHING in this thread... but I sure don?t recall anyone saying you should get rid of your IC-7610.

Hi Charlie, The '7610 is an impressive and capable radio. We have one in our shop and have put it on the air. It's a bit of apples/oranges comparison to the K4, though. Since you asked ... here are some K4 characteristics to consider: * Controls -- The K4's UI is quite different, borrowing heavily from the K3, but with an infusion of versatility due to the 7" display. It has the widest available viewing angle and is very bright.

For example, we could quickly and cost-effectively incorporate a new ADC or DAC. Call it planned non-obsolescence. This the 20th anniversary of the K2, and the 10th anniversary of the K3. Both are still shipping. * Extensibility -- In addition to the HDR module, the user will be able to add a VHF/UHF module, which in turn could morph in the future. This philosophy extends to software as well, given the K4's general-purpose computing module [not Windows]. I like to think of it as our "app engine," limited only by the imagination of our software team and other talented contributors. * External monitor output -- HDMI, not DVI. (To each his own?) * Tuning aid -- The "mini-pan" is one of our favorite features of the K4. When you tap on a signal you don't just get a geometric magnification of the main panadapter's pixels; you get a re-sampled, high-resolution spectral display of as narrow as +/- 1 kHz (varying per mode). This is great for signal auto-spotting and left/right peak search. The mini-pan is per-receiver and can either be turned on automatically or by tapping either S-meter. ?

These products are thought to be manage by operative systems and drivers (like Windows or Mac or Linux), this is not the case of the K4 that have a custom "OS" and can't manage that kind of devices. Maybe you can use more complicated and expensive devices thought to be used with RJ-45 ports, where this device use a DHCP and give an ip address to the RJ-45 port creating a private network between the RJ-45 and the device, afterwards the device can access the WIFI network with his wifi adapter and work like a bridge between the two network. In this way, maybe, you can connect the K4 to the wifi in a more "natural" way. Like this one for example: https://www.amazon.com/Vonets-VAR11N-300-Multi-Functional-Wireless-Portable/dp/B01199OGK0/ref=sr_1_fkmrnull_1_sspa?keywords=vonets+VAR11+N-300&qid=1558431899&s=gateway&sr=8-1-fkmrnull-spons&psc=1 Best regards, Graziano Roccon IW2NOY / W2NOY Il 21/05/2019 06:26 Alan ha scritto: > For less than $10 you can buy a little WiFi adapter that plugs into a > USB port.?

These products are thought to be manage by operative systems and drivers (like Windows or Mac or Linux), this is not the case of the K4 that have a custom "OS" and can't manage that kind of devices. Maybe you can use more complicated and expensive devices thought to be used with RJ-45 ports, where this device use a DHCP and give an ip address to the RJ-45 port creating a private network between the RJ-45 and the device, afterwards the device can access the WIFI network with his wifi adapter and work like a bridge between the two network. In this way, maybe, you can connect the K4 to the wifi in a more "natural" way.

Wayne, Since 2015, N4CC and I have been operating a remote station on the FL/GA state line. A K3 and RemoteRig have been the centerpiece of the station. Hopefully, Elecraft has been getting feedback from its remote users on various networking and operability issues. While we consider the value of replacing the K3 with a K4, here's my list of items that would make the decision easier: 1) Incorporate variable panadapter streaming bandwidth, much the way that VNC users can change streaming bandwidth on the fly. Our station uses a Verizon 4G/LTE link on the "last mile." We're presently limited to a 30GB/month plan and between two users, we often approach the monthly limit with RemoteRig and VNC, especially during DXpedition activity. At low streaming settings, the display would need to show reasonably good resolution/screen refresh to be of any added value to us. Keep in mind that not all remote users have access to unlimited data plans; 2) Ability to kill audio streaming on the fly. When operating FT8, RTTY and other digital modes remotely with the digital applications residing on a host desktop via VNC or TeamViewer, there's absolutely no need to stream audio. An audio kill switch would save a tremendous amount of monthly data for users like us on a monthly data plan. 3) CW performance can be improved over RemoteRig. Instead of sending "dit and dah" elements, consider sending ASCII characters or a variant where full characters are transmitted in a data packet. K1EL remote software and the Ten Tec Omni VII stream CW in complete characters. In my experience, those systems have been far superior to that of RemoteRig. For five years, I used a pair of linked K1EL Winkeyers and never had the CW stuttering and missed keyed element issues I experience with RemoteRig. No doubt other users have had no issues but this is important to users like us who are dependent on multiple media forms in the complete transmission path (e.g., hybrid-fiber-coaxial to 4G/5G/LTE) where jitter and latency are constantly changing on the network. 4) Until a "K4 Mini" is released, it makes little sense to purchase a K4 if a companion K4 is required at the control point. That's a lot of dough sitting unused on the desktop. Any idea as to when a mini version will be released? These are my issues based on four years of remote experience with a K3. I'm sure other remote users may want to chime in with their own. All feedback is good.

Hi Charlie, The '7610 is an impressive and capable radio. We have one in our shop and have put it on the air. It's a bit of apples/oranges comparison to the K4, though. Since you asked ... here are some K4 characteristics to consider: * Controls -- The K4's UI is quite different, borrowing heavily from the K3, but with an infusion of versatility due to the 7" display. It has the widest available viewing angle and is very bright. (K4 tire-kickers at Dayton were extremely complimentary about the display, which was gratifying after 200 or so iterations on the concept drawing by yours truly.) There are three multifunction knobs (not just one), each mapped to a semantic group, e.g. "XMIT". Their functions adapt to the current operating mode, etc. On the right side of the radio there are three 400-count, ball-bearing drive optical shaft encoders, for VFO A, VFO B, and RIT/XIT offset. No need to multi-task one or two controls. Bottom line: ease of use. If you do get stuck, there's a built-in help system. * Dynamic range -- The K4 is a direct-sampling, dual-receiver radio in its base configuration. But those in high-signal environments can add the dual superhet module to realize a 20 to 25 dB improvement in headroom (blocking dynamic range) over any radio that is direct-sampling only. This is the same delta as, for example, a K3S vs. any other non-superhet on Sherwood's list. * Portability -- The K4 weighs only about 10 pounds, draws only about 2 amps on RX, and can run down to 11 volts. It will try to drag you off to a Field Day site or remote island if not bolted to your desk. ? Remote control -- The K4 comes with remote-control via Ethernet built in. One K4 can controlled by another, or by a tablet or PC. Eric must have demonstrated this 500 times at Dayton and I daresay he's getting good at it. * Modularity -- We segregated the K4's modules in such a way as to facilitate easy update to units in the field if/when new tech becomes available. For example, we could quickly and cost-effectively incorporate a new ADC or DAC. Call it planned non-obsolescence. This the 20th anniversary of the K2, and the 10th anniversary of the K3. Both are still shipping. * Extensibility -- In addition to the HDR module, the user will be able to add a VHF/UHF module, which in turn could morph in the future. This philosophy extends to software as well, given the K4's general-purpose computing module [not Windows]. I like to think of it as our "app engine," limited only by the imagination of our software team and other talented contributors. * External monitor output -- HDMI, not DVI. (To each his own?) * Tuning aid -- The "mini-pan" is one of our favorite features of the K4. When you tap on a signal you don't just get a geometric magnification of the main panadapter's pixels; you get a re-sampled, high-resolution spectral display of as narrow as +/- 1 kHz (varying per mode). This is great for signal auto-spotting and left/right peak search. The mini-pan is per-receiver and can either be turned on automatically or by tapping either S-meter. ? IO -- The K4's IO is a superset of the K3's, meaning it comes with all of the analog and control I/O you might need as well as 4 USB ports, Ethernet, etc. * Antenna sources -- There are up to 3 ATU antenna jacks and up to 5 receive antenna inputs. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From a.durbin at msn.com Tue May 21 09:33:57 2019 From: a.durbin at msn.com (Andy Durbin) Date: Tue, 21 May 2019 13:33:57 +0000 Subject: [Elecraft] K4 Remote Control Message-ID: "3) CW performance can be improved over RemoteRig.

If Elecraft has partnered with Microbit, then that saved a whole lot of remote development time and RemoteRig could easily be embedded into the K4, either on it's own board, or on the K4 I/O interface. If that's the case, I hope an option could be added to transmit complete characters in addition to the current configuration.

Last year I moved to the Flex because at that time it appeared to be the best option in the SDR world. I?ve always loved Elecraft but the K3S and P3 were a bit out of my price range at the time and didn?t have some of the features I was looking for since I was looking more to SDR type products. Fast forward to today with the K4 I am super impressed and it?s features out way those of the Flex. That?s my opinion. One in particular, which Wayne stated in this tread is the K4?s modularity. This is one thing that has been in the back of my mind ever since owning the Flex. As far a I can tell Flex (along with Icom, Yeasu, Kenwood) doesn?t have the ability built into the hardware. At least they haven?t said and I?m sure they would have if they did. This is a concern. Not only do Flex owners have to pay for software updates, at what point will they have to upgrade the hardware to take advantage of new features in software that can only be used with newer hardware such as ADC? That?s huge in my mind and with Elecraft track record with older models still being sold is a big advantage. The 7610 and radios like Flex are wonderful radios, don?t get me wrong, but I feel Elecraft is on the right and better track when it comes to listening to their customers and producing a radio that works and works well for all types of ham operator. Hopefully I?ll be a K4 owner one day so I can have that piece of mind that it will serve well for years to come.

Other replies indicate easy/cheap WiFi devices that can be driven by RJ45, so that solves operating from a minipad like the ipad, which has no physical connections. I suppose that was what was demo'd at Hamvention. 73, Ed - KL7UW Date: Mon, 20 May 2019 21:57:15 -0700 From: "Eric Swartz - WA6HHQ, Elecraft" To: Brian Denley Cc: Elecraft Reflector Subject: Re: [Elecraft] Elecraft / IC-7610 comparison Message-ID: <81C43842-A657-4C98-B7B2-BBF059239B87 at elecraft.com> Content-Type: text/plain; charset=utf-8 Hi Brian, Its a regular RJ-45 Ethernet jack on the rear of the K4. (I believe it is gigabit ethernet..) Usually your network router provides the wifi to connect wirelessly in the house (also including a DCHP iP address server.) Embedding wifi in the radio is problematic as it is a rapidly evolving technology with regular changes in security features, speed etc that are best handled by router sw and hw upgrades. Its unlikely wifi will stay constant over the radio's life. 73, Eric elecraft.com 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From ns9i at bayland.net Tue May 21 11:07:13 2019 From: ns9i at bayland.net (dgb) Date: Tue, 21 May 2019 10:07:13 -0500 Subject: [Elecraft] K4 Remote Control In-Reply-To: References: Message-ID: Will a K3 be able to talk to the K4 remotely?

If my memory serves me correctly the discussion was around the possibility of there being a Linux machine in the radio. Presuming there is in fact s Linux machine in the K4, then it is probably tasked with managing I/O and networking, in addition to the remote connection server, and whatever else. So there would be a standard OS type available for managing thing like a wireless adapter. Guesswork of course, since (at least in the videos I saw) there was no explicit discussion of the network environment in the booth or exactly how the K4 was connected to the wireless network. Wayne did comment that they were using the infrastructure installed at the hamfest facility. But there was clearly a wireless connection to the Microsoft table computer, which was running client side remote software in a Linux virtual machine. Eventually, there will be block diagrams of the control/processing structure in the radio .. and more will be known. Grant NQ5T K3 #2091 KX3 #8342 > > > this is not good for K4.

Hi Charlie, The '7610 is an impressive and capable radio. We have one in our shop and have put it on the air. It's a bit of apples/oranges comparison to the K4, though. Since you asked ... here are some K4 characteristics to consider: * Controls -- The K4's UI is quite different, borrowing heavily from the K3, but with an infusion of versatility due to the 7" display. It has the widest available viewing angle and is very bright. (K4 tire-kickers at Dayton were extremely complimentary about the display, which was gratifying after 200 or so iterations on the concept drawing by yours truly.) There are three multifunction knobs (not just one), each mapped to a semantic group, e.g. "XMIT". Their functions adapt to the current operating mode, etc. On the right side of the radio there are three 400-count, ball-bearing drive optical shaft encoders, for VFO A, VFO B, and RIT/XIT offset. No need to multi-task one or two controls. Bottom line: ease of use. If you do get stuck, there's a built-in help system. * Dynamic range -- The K4 is a direct-sampling, dual-receiver radio in its base configuration. But those in high-signal environments can add the dual superhet module to realize a 20 to 25 dB improvement in headroom (blocking dynamic range) over any radio that is direct-sampling only. This is the same delta as, for example, a K3S vs. any other non-superhet on Sherwood's list. * Portability -- The K4 weighs only about 10 pounds, draws only about 2 amps on RX, and can run down to 11 volts. It will try to drag you off to a Field Day site or remote island if not bolted to your desk. ? Remote control -- The K4 comes with remote-control via Ethernet built in. One K4 can controlled by another, or by a tablet or PC. Eric must have demonstrated this 500 times at Dayton and I daresay he's getting good at it. * Modularity -- We segregated the K4's modules in such a way as to facilitate easy update to units in the field if/when new tech becomes available. For example, we could quickly and cost-effectively incorporate a new ADC or DAC. Call it planned non-obsolescence. This the 20th anniversary of the K2, and the 10th anniversary of the K3. Both are still shipping. * Extensibility -- In addition to the HDR module, the user will be able to add a VHF/UHF module, which in turn could morph in the future. This philosophy extends to software as well, given the K4's general-purpose computing module [not Windows]. I like to think of it as our "app engine," limited only by the imagination of our software team and other talented contributors. * External monitor output -- HDMI, not DVI. (To each his own?) * Tuning aid -- The "mini-pan" is one of our favorite features of the K4. When you tap on a signal you don't just get a geometric magnification of the main panadapter's pixels; you get a re-sampled, high-resolution spectral display of as narrow as +/- 1 kHz (varying per mode). This is great for signal auto-spotting and left/right peak search. The mini-pan is per-receiver and can either be turned on automatically or by tapping either S-meter. ? IO -- The K4's IO is a superset of the K3's, meaning it comes with all of the analog and control I/O you might need as well as 4 USB ports, Ethernet, etc. * Antenna sources -- There are up to 3 ATU antenna jacks and up to 5 receive antenna inputs. 73, Wayne N6KR ------------------------------ Message: 11 Date: Mon, 20 May 2019 21:52:45 -0400 From: "W1GO (Joe)" To: Elecraft Reflector Subject: [Elecraft] AX1 first contact Message-ID: Content-Type: text/plain;??? charset=utf-8 All, First use of AX1 today in New York?s Adirondack Mountains.?

(I believe it is gigabit ethernet..) Usually your network router provides the wifi to connect wirelessly in the house (also including a DCHP iP address server.) Embedding wifi in the radio is problematic as it is a rapidly evolving technology with regular changes in security features, speed etc that are best handled by router sw? and hw upgrades. Its unlikely wifi will stay constant over the radio's life. 73, Eric elecraft.com _..._ > On May 20, 2019, at 8:24 PM, Brian Denley wrote: > > Wayne: > When you mention that the K4 has Ethernet (which means cables to me), it must also have WiFi if you can control with tablets, no? > > Brian > KB1VBF > Sent from my iPad > > On May 20, 2019, at 8:39 PM, Wayne Burdick wrote: > >>> Charlie, K3ICH, wrote: >>> >>> OK, So why should I [pejorative deleted] my IC-7610 for a K4? >> >> >> Hi Charlie, >> >> The '7610 is an impressive and capable radio.

Hi Charlie, The '7610 is an impressive and capable radio. We have one in our shop and have put it on the air. It's a bit of apples/oranges comparison to the K4, though. Since you asked ... here are some K4 characteristics to consider: * Controls -- The K4's UI is quite different, borrowing heavily from the K3, but with an infusion of versatility due to the 7" display. It has the widest available viewing angle and is very bright. (K4 tire-kickers at Dayton were extremely complimentary about the display, which was gratifying after 200 or so iterations on the concept drawing by yours truly.) There are three multifunction knobs (not just one), each mapped to a semantic group, e.g. "XMIT". Their functions adapt to the current operating mode, etc. On the right side of the radio there are three 400-count, ball-bearing drive optical shaft encoders, for VFO A, VFO B, and RIT/XIT offset. No need to multi-task one or two controls. Bottom line: ease of use. If you do get stuck, there's a built-in help system. * Dynamic range -- The K4 is a direct-sampling, dual-receiver radio in its base configuration. But those in high-signal environments can add the dual superhet module to realize a 20 to 25 dB improvement in headroom (blocking dynamic range) over any radio that is direct-sampling only. This is the same delta as, for example, a K3S vs. any other non-superhet on Sherwood's list. * Portability -- The K4 weighs only about 10 pounds, draws only about 2 amps on RX, and can run down to 11 volts. It will try to drag you off to a Field Day site or remote island if not bolted to your desk. ? Remote control -- The K4 comes with remote-control via Ethernet built in. One K4 can controlled by another, or by a tablet or PC. Eric must have demonstrated this 500 times at Dayton and I daresay he's getting good at it. * Modularity -- We segregated the K4's modules in such a way as to facilitate easy update to units in the field if/when new tech becomes available. For example, we could quickly and cost-effectively incorporate a new ADC or DAC. Call it planned non-obsolescence. This the 20th anniversary of the K2, and the 10th anniversary of the K3. Both are still shipping. * Extensibility -- In addition to the HDR module, the user will be able to add a VHF/UHF module, which in turn could morph in the future. This philosophy extends to software as well, given the K4's general-purpose computing module [not Windows]. I like to think of it as our "app engine," limited only by the imagination of our software team and other talented contributors. * External monitor output -- HDMI, not DVI. (To each his own?) * Tuning aid -- The "mini-pan" is one of our favorite features of the K4. When you tap on a signal you don't just get a geometric magnification of the main panadapter's pixels; you get a re-sampled, high-resolution spectral display of as narrow as +/- 1 kHz (varying per mode). This is great for signal auto-spotting and left/right peak search. The mini-pan is per-receiver and can either be turned on automatically or by tapping either S-meter. ?

I am a long time user of Flex SDR radios. I still have an operational 5000, and my main SDR for the past half dozen or so years has been a 6700. All the while I have kept a conventional radio along side. I like to listen and experiment with the Flex, but it's the conventional radio I really love to operate. My conventional radio is a now antique Kenwood TS-950sdx. I have kept it so long because in searching I have not found a replacement. The K3s has long been a top candidate and if I lost my old friend, would have gone that route. The Icom 7610 looks interesting. It's more of a hybrid, with SDR features but built like a conventional radio. It had been highly recommended, and I was considering it. Then a few days ago along comes the K4 announcement. My long experience with both conventional and SDR radios brought me to realize immediately, this is it! Wayne's earlier email hits many of the spots that are attractive. I especially like the mini-panadapters, which I do with the 6700, but in a very cumbersome way. But the main attraction is the promise that it will behave like -- have the look and feel of -- a conventional radio, while being saturated with SDR features to the core. I actually pre-ordered a K4D soon after absorbing the specifications. So while the 6700 will remain an important part of my station for the forseeable future, I'm on board and excited about the coming K4! Tks, 73 Ed w2rf E.H.

Last year I moved to the Flex because at that time it appeared to be the best option in the SDR world. I?ve always loved Elecraft but the K3S and P3 were a bit out of my price range at the time and didn?t have some of the features I was looking for since I was looking more to SDR type products. Fast forward to today with the K4 I am super impressed and it?s features out way those of the Flex. That?s my opinion. One in particular, which Wayne stated in this tread is the K4?s modularity. This is one thing that has been in the back of my mind ever since owning the Flex. As far a I can tell Flex (along with Icom, Yeasu, Kenwood) doesn?t have the ability built into the hardware. At least they haven?t said and I?m sure they would have if they did. This is a concern. Not only do Flex owners have to pay for software updates, at what point will they have to upgrade the hardware to take advantage of new features in software that can only be used with newer hardware such as ADC? That?s huge in my mind and with Elecraft track record with older models still being sold is a big advantage. The 7610 and radios like Flex are wonderful radios, don?t get me wrong, but I feel Elecraft is on the right and better track when it comes to listening to their customers and producing a radio that works and works well for all types of ham operator. Hopefully I?ll be a K4 owner one day so I can have that piece of mind that it will serve well for years to come.

After a brief and very unsatisfactory experience with a Kenwood 2000, all my HF rigs have been Elecraft and I have always gone kit. I currently own a well-populated K3 with some of the K3s modifications. I am less concerned about bells and whistles than pure performance. Can I hear them? Can I penetrate through under adverse conditions and get a QSL? Elecraft has always delivered and has always been at or near the top in performance. I have confidence with Elecraft that I am at the top in quality and when I can't get through it is not the fault of the radio. I know this is a smart company. It is an American company that has survived and excelled in a market dominated by foreign competition. On top of it, this is an organization that listens to and takes care of its customers. If something goes wrong they will help me sort it out and fix it. And they will do it for a reasonable price. I don't see myself ever going anywhere else. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dick Sent: Tuesday, May 21, 2019 6:40 AM To: elecraft at mailman.qth.net Subject: [Elecraft] K4 And after reading all the comments on ?why buy a K4, or even Elecraft when I have Icoms et al, etc.? .

Message-ID: <712213d0-0eb7-41f8-84b5-38e49a370ff1@www.fastmail.com> Hi, I've just completed my K2 up to the PLL reference oscillator. Initially when I assembled it the PLL reference oscillator would not oscillate at all. No reading on internal counter. I popped it on my external Racal counter and still dead. After tracing the problem out I found that the voltage on input to the varactors was pegged at 7.07V which was too high for the oscillation to carry on. I lifted one end of R19 on the output of U6A and the thing oscillates fine isolating this to a control voltage problem. Next I checked voltages on the thermistor board and input of the opamp. All good. However the input to U6A pin 3 from the LTC1451 DAC is stuck at 4.095V (top end of DAC range by the looks of it) which is forced up by the opamp. Popped U5 DIN on the scope and spun the VFO and it sends the same data word to the DAC every time regardless of VFO position. The CLK and CS lines are doing their thing correctly. Anyone got any ideas why the control word is the same? VFO reading on display is changing fine. What can I do to get out of this hole? Any help appreciated.

It's an upgrade from the KAT3, with three RX/TX antenna jacks and the ability to select any one of the three as an RX-only jack that bypasses the ATU.

I'm hoping for UHD (4K), that display would be beyond spectacular (and I'd presume that the linux machine would manage that to take the load off the K4 RF portion). Well done for moving to HDMI, as monitors are sharper AND cheaper than SVGA these days.? It could also allow a split screen (picture in picture) on a capable TV or monitor for other things to be displayed at the same time. Is it a safe presumption that audio is routed through the RJ45 as well so that no other wiring is required for remote?

I believe the initialization of that linearisation table that is locking it all up and driving the 12 bit DAC to max voltage. Cal PLL will not work because there is no lock. So it is stuck. Still need to track down the problem and then I'm thinking we have to come up with a way to redo the table to something nominal to move forward. 73, Dave, W8FGU On May 21, 2019 11:21:32 "Chris Smith" wrote: > Hi, > > Thanks for the reply.

As for the 7.07 volts from U6A pin 1, that is not necessarily the cause of the problem (Q19 should oscillate even with almost 8 volts from U6 pin 1) - if it does not, then the problem is Q19. While waiting for a replacement J310 from Elecraft, try putting a small value capacitor from the source of Q19 to ground - use 10 to 15pF. Then measure the PLL Reference oscillator range using the counter probe in TP3 and entering CAL FCTR in the menu. You should have oscillation at both the low (BAND-) and high (BAND+) and the frequency of the high end should be near 12100 kHz. Another potential problem if the voltage on U5 pin 7 (and as a result U6 pin 1) can be that the /DAC2CS input to U5 pin 3 is always at or near ground - check for that condition, and if present, find the solder bridge. That signal line should go to ground as you rotate the VFO, but otherwise should be at 5 volts. You will need an oscilloscope to see the negative transitions. 73, Don W3FPR On 5/21/2019 12:27 PM, Chris Smith wrote: > Hi, > > I've just completed my K2 up to the PLL reference oscillator. > > Initially when I assembled it the PLL reference oscillator would not oscillate at all.

I assume this is a bootstrap problem then i.e. the J310 has to be oscillating in the default state before the VCO linearisation can run and set up the LUT inside the EEPROM. Making a large assumption there of course as I can't see the source code! I tried the 10pF trick from another thread that you mentioned before after researching this issue and unfortunately that didn't start the oscillation. I did some experiments and will complete one more: Experiment 1 .... Did a hard reset (456+power up) to see if it reset the data. It showed the initialisation info message. FAIL Experiment 2 .... I just checked the VXO range by pulling R19 and using another bench supply. The thing gives a relatively reliable 3v p-p until the varactor control voltage hits 6.8V then it stalls. Obviously as DAC output eventually ends up at 7.07V it's game over straight up. Experiment 3 .... If I leave R19 lifted and run the PLL cal it doesn't throw info 232 straight away but appears to hang, probably because there's no control voltage doing anything which is hopeful if it works how I think it does! Experiment 4 .... (in progress) I'm going to put a J309 in (I don't have any spare J310s I don't think and this is same FET but binned with different Idss) and see if it oscillates across the full range. I will then run PLL cal. If that works then it'll at least clarify first assumption. I checked /DAC2CS and it does indeed go low during the load operation. The issue is the control data sent to the DAC is the same. Thanks for your help. Some ideas to try!

No reading on internal counter. I popped it on my external Racal counter and still dead. After tracing the problem out I found that the voltage on input to the varactors was pegged at 7.07V which was too high for the oscillation to carry on. I lifted one end of R19 on the output of U6A and the thing oscillates fine isolating this to a control voltage problem. > > > From eric at elecraft.com Tue May 21 14:58:55 2019 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Tue, 21 May 2019 11:58:55 -0700 Subject: [Elecraft] Where it's made In-Reply-To: <2022cdd0-4be4-9ddc-79bc-5821a804a015@montac.com> References: <20190521154930.E557C149B5D1@mailman.qth.net> <90652668-A5F6-4069-9773-61C022F673B6@w2xj.net> <693567408.4003474.1558464081041@mail.yahoo.com> <2022cdd0-4be4-9ddc-79bc-5821a804a015@montac.com> Message-ID: Let's end this thread for now in the interest of keeping list traffic manageable for other readers. 73, Eric Moderator etc. /elecraft.com/ From jh at hoffmaninv.com Tue May 21 15:24:28 2019 From: jh at hoffmaninv.com (W8JH) Date: Tue, 21 May 2019 12:24:28 -0700 (MST) Subject: [Elecraft] Where it's made In-Reply-To: References: <20190521154932.42A9A149B5E1@mailman.qth.net> <90652668-A5F6-4069-9773-61C022F673B6@w2xj.net> Message-ID: <1558466668924-0.post@n2.nabble.com> And we should respect that the Elecraft list has global coverage and there is a global customer base. 73, Joe, W8JH ----- 73, Joe, W8JH K3s, KPA 500, KAT 500 and KX3 happy user. -- Sent from: http://elecraft.365791.n2.nabble.com/ From archernf at gmail.com Tue May 21 15:25:17 2019 From: archernf at gmail.com (Neil) Date: Tue, 21 May 2019 15:25:17 -0400 Subject: [Elecraft] Reflector format Message-ID: <5CE4509D.1080306@gmail.com> It is a pity that the present format of the reflector does not allow a person to mouse click on a particular post so that one does not have to scroll thru spots that may not be of interest.

These products are thought to be manage by operative systems and drivers (like Windows or Mac or Linux), this is not the case of the K4 that have a custom "OS" and can't manage that kind of devices. Maybe you can use more complicated and expensive devices thought to be used with RJ-45 ports, where this device use a DHCP and give an ip address to the RJ-45 port creating a private network between the RJ-45 and the device, afterwards the device can access the WIFI network with his wifi adapter and work like a bridge between the two network. In this way, maybe, you can connect the K4 to the wifi in a more "natural" way.

I've been doing that for almost thirty years, originally with PMMail, then (and now) with Thunderbird. First, incoming mail is sorted into separate folders, one for each reflector that I read. Then it's easy and fast to read and delete (or keep) them. Even Yahoo's Windows interface makes it easy to do this too. 73, Jim K9YC From donwilh at embarqmail.com Tue May 21 16:28:16 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 21 May 2019 16:28:16 -0400 Subject: [Elecraft] Reflector format In-Reply-To: <5CE4509D.1080306@gmail.com> References: <5CE4509D.1080306@gmail.com> Message-ID: <164c2859-9c67-6207-4595-962989e5f716@embarqmail.com> Neil, If you receive the individual emails using a good email client running on your computer, you can do just as you requested. Unfortunately, it does not work that way for the digest nor if you are reading via webmail. My email client has a filter set to move all incoming email with "[Elecraft]" in the subject line to a folder that I have named "Elecraft" - that way I do not have all those posts in my main Inbox. I can open the Elecraft folder and read or delete individual emails and/or respond to those I wish to reply to. In other words, I have my own version of a "digest" in that folder that I can handle like any other email I receive. 73, Don W3FPR On 5/21/2019 3:25 PM, Neil wrote: > It is a pity that the present format of the reflector does not allow a > person to mouse click on a > particular post so that one does not have to scroll thru spots that may > not be of interest.

This from James Pastorfield: ?Educator, Author, Contester Fred Cady, KE7X, SK Fred Cady, KE7X, of Bozeman, Montana, died on May 16. An ARRL Life Member, he turned 77 earlier this month. Cady was a professor emeritus of electrical and computer engineering at Montana State University. He co-authored The Successful Ham Radio Operator?s Handbook with Vic DiCiccio, VE3YT. Cady also wrote several manuals on how to use Elecraft equipment. Licensed in 1959, Cady earned a PhD in electrical engineering from the University of Canterbury in New Zealand, and was a senior member of the Institute of Electrical and Electronics Engineers (IEEE). He taught for more than 40 years and published five textbooks on microcomputers. An avid CW contester, Cady was a member of the world record-holding Team Vertical contest group?. What a loss to not only his family, but to the Amateur Radio fraternity, especially Elecraft owners who use his books as a bible. RIP OM. 73, Alan.

I have not found that the EEPROM has been the source of the problem, but rather Q19. Q19 should oscillate with anywhere between 0 volts and 8 volts on the varactors. Before assuming it is a possible EEPROM problem, add the capacitor I indicated and see if it works. You should still replace Q19.

I think he was just asking about how to configure his KX2 to transmit and receive FT8 with his Asus computer, and maybe a data mode setting for FT8 specifically...though it's not necessary, as the DATA A is perfectly usable for FT8, I've done it with my KX3. Yes, Chris, DATA A is the setting you want to use. You want the phones from the radio going to the mike input on the PC, and mike on the KX2 going to the speakers on the PC. Turn off MIC BIAS and set PTT to OFF. CAT should work fine to key it. I just use the Elecraft USB control cable for that. If your PC doesn't have separate mike and speaker jacks, you can either make a special cable that splits them out, or you can use a USB sound card dongle. Then configure WSJT-X to use the appropriate sound card settings. That's basically what I do with my KX3, I just have to jump through some extra hoops on my Win7 machine to get WSJT-X to play nice with it. I have no trouble at all with a small Asus VivoMini Win10 machine, though. I'm not familiar with the Zenbook, so you may have some tinkering to do, but that's basically it. 73, Gwen, NG3P On Tue, May 21, 2019 at 11:24 PM rich hurd WC3T wrote: > No nudging needed.

Oscillator Range Test Problem. Message-ID: I am building an older QRP K2 kit ser. # 2438 Ver. A in the Alignment and test section Part 11. pg. 57, the PLL Ref. Oscillator Range Test is out of limits. The Reference High and Low frequencies are OK with readings (12100.53 high and 12089.43 low) with range limits of 11.5 - 25 KHz but it is low, 11.1 KHz. Is this a problem ? In the PLL troubleshooting section all readings are OK except the BFO buffer output (0.025 - 0.070 VRMS ) is slightly high 0.076 VRMS. Is this a problem ?

Be able to select a window on the panadapter screen using point/click with the mouse... i.e., a subset of the displayed spectrum that could be variable for both width and position.? For example, 2 KHz or 5 5 KHZ or 10 KHz window centered anywhere on the band, including from either receiver, or both receivers simultaneously. 2.? Change the waterfall to scroll from right to left below the spectrum display for only that subset window (or windows if from both receivers). 3.? Within reason, be able to adjust the rate of the waterfall(s), including the capability to pause/resume either one with either a button push on the K4 or a key press on a keyboard. I used to have this same thing set up on my computer monitor by feeding the audio from my K3 into the sound card of my computer and running both AutoHotKey and VE3NEA's CW Skimmer in "audio mode" (3 KHz bandwidth), but with decoding turned off.?? CW Skimmer has a very high resolution waterfall and it runs from right to left, and AutoHotKey allowed me to assign CW Skimmer's pause/resume to a couple of keyboard keys.? I could even run the audio from both receivers in separate windows since CW Skimmer can run multiple copies of itself.? The biggest problem with it, other than the hassle of setting it all up, was the monitor space required to run N1MM (both receivers) plus two long skinny windows of CW Skimmer. The result is that if I missed a character or two of a callsign or report while running stations in a CW contest (distraction, room QRM, fumbled logging requiring a correction, me being a poor operator, whatever) I could hit the pause key (if needed) and visually read the dots/dashes of the character I missed, reading from left to right as many of us are used to.? The way I had everything set up with the CW Skimmer windows set to full width of the monitor, I could get about 8 seconds of waterfall history, which is huge.? I only had to use it once in a while, but on those occasions it definitely saved me from having to ask for a repeat, and it didn't take me long to get used to visually decoding since I would mentally read the dots and dashes as dits and dahs.? I queried a couple of major contest committee members about the practice at the time and nobody could find fault with it under the rules.? After all, I'm still doing all the decoding. I think the K4 could potentially implement this as a useful feature for CW contesters, and possibly even have benefit for DXers or others who might want to simply monitor activity on a different frequency without having to listen to it.? Reading left to right is far more natural than down-to-up, and the capability for several seconds of history is useful as well. Comments appreciated. 73, Dave??

Often non-AV products use DVI or DisplayPort because of cost / licensing vs HDMI. This is why you see DVI and DP rather than HDMIi on a lot of computer monitors. I am guessing the video on the K4 comes from an SBC and the HDMI "tax" has already been paid. 73.

All good. What I'm referring to is packet-generated characters while using *paddles*. Instead of dit and dah elements, the keyer interprets paddle closure and creates an ASCII or similar character. For example, the worst-case character delay when using this mode is the number zero (0). The character isn't sent until the last "dah" element is formed and the dah paddle is released. One may think this creates a huge timing problem on the air, but it really doesn't in actual practice. To the best of my knowledge this mode of character forming was first used by Ten Tec in the Omni VI, then adopted by K1EL in his WinkeyerUSB device.

The radio computer can accept multiple, concurrent connections from front panels, tablets, and other computers, either on a local network or across the Internet. That's what they demonstrated at Dayton - an operational K4 being simultaneously controlled by its own front panel, another K4, and a tablet. I don't know if any of this required collaboration with microBit (RemoteRig), but those RRC boxes are definitely out of the picture. The big bennie for me out of all this is that I will be able *eventually* to set up my remote station once and access it locally, from a K4/0 at my other QTH, or from my laptop when traveling. I say "eventually" because the K4/0 will be released significantly later. They've also mentioned supporting the K*Pod external knob from the laptop/tablet implementations, thereby providing that all-important "big knob" for VFO tuning. Sounds great; eager to get my hands on it! 73, /Rick N6XI -- Rick Tavan Truckee, CA On Tue, May 21, 2019 at 6:40 AM Paul Christensen wrote: > >"If K4 uses a super-set of K3 commands then I assume it would support KY > mode ( ASCII characters transmitted over the CAT interface) for CW.

Overall it's functioning very well now, and I've been working some nice DX. I have one question at the moment. Especially under certain band conditions, audio level sent from the K3S to the apps seems low. With my prior rig (Icom 7300), my primary way of dialing up and down the audio level sent from the rig to the computer was by adjusting the RF Gain knob, which if turned far enough (i.e. too far) would virtually always put the WSJT-X received signal meter far into the red. With the K3S, I gather it's normal to operate with RF Gain turned fully clockwise all of the time. The only other adjustment I've found on the K3S is Config > Line Out. The default appears to be 10, and even if I take it up to the maximum of 100 it doesn't put WSJT-X into the red. (Not that operating in the red is desirable -- since clipping will occur -- but in the past I've found that if the rest of the band is quiet enough, WSJT-X's ability to decode a very faint DX signal may be improved by bring the received audio level up just to the edge of the red.) I'm much newer to FLdigi, where the signal levels I'm seeing seem chronically low, but that may reflect band conditions (and, I'm told by ops more experienced with it, that tends to be the way FLdigi always looks compared to WSJT-X). In the Mac's audio system, there are no level adjustments for the input USB Codec, and I don't think there are relevant adjustments in either WSJT-X or FLdigi. So my question is, are there any other settings or adjustments to experiment with on the K3S that might give me more flexibility on audio level sent by USB to the Mac? If not, would using a sound card-type device rather than USB be an alternative way to have more ability to control the level of received audio sent to the computer?

Why is there a KAT4 on the pre-order list. Like on most of our radios, the KAT4 ATU is optional and can be added at any time.

I have come to believe that it does not - it just sends ASCII characters in a format acceptable for the WinKeyer." I spent some time looking into this before I purchased my WinKeyer USB. Although N1MM+ does not directly support KY mode it is possible to build substitution macros that do produce KY command strings. I lost interest in that because Kenwood KY mode requires a full KY buffer before it will transmit. This makes the macros unusable for variable length substitutions such as call sign and serial number. However, I found the K3 does not require a fixed length full buffer to transmit and it is reported to work ok with variable length macro substitutions. Still a long way from converting paddle swipes to ASCII. 73, Andy, k3wyc From esteptony at gmail.com Wed May 22 15:04:25 2019 From: esteptony at gmail.com (Tony Estep) Date: Wed, 22 May 2019 14:04:25 -0500 Subject: [Elecraft] K4HD In-Reply-To: <20190522112822.1fa1e31b6b6b329ecc65be958babcc1f.21ad46ca5e.wbe@email09.godaddy.com> References: <20190522112822.1fa1e31b6b6b329ecc65be958babcc1f.21ad46ca5e.wbe@email09.godaddy.com> Message-ID: On Wed, May 22, 2019 at 1:29 PM Dave New, N8SBE wrote: > ...in 2009. ...I was put off by the Flex, both for lack of QSK CW... > =========== If you were thinking of using a Flex for CW in 2009 and you didn't do it, you saved yourself a LOT of heartache.

Especially under certain band conditions, audio level sent from the K3S to the apps seems low. With my prior rig (Icom 7300), my primary way of dialing up and down the audio level sent from the rig to the computer was by adjusting the RF Gain knob, which if turned far enough (i.e. too far) would virtually always put the WSJT-X received signal meter far into the red. With the K3S, I gather it's normal to operate with RF Gain turned fully clockwise all of the time. The only other adjustment I've found on the K3S is Config > Line Out. The default appears to be 10, and even if I take it up to the maximum of 100 it doesn't put WSJT-X into the red. (Not that operating in the red is desirable -- since clipping will occur -- but in the past I've found that if the rest of the band is quiet enough, WSJT-X's ability to decode a very faint DX signal may be improved by bring the received audio level up just to the edge of the red.) I'm much newer to FLdigi, where the signal levels I'm seeing seem chronically low, but that may reflect band conditions (and, I'm told by ops more experienced with it, that tends to be the way FLdigi always looks compared to WSJT-X). > > In the Mac's audio system, there are no level adjustments for the input USB Codec, and I don't think there are relevant adjustments in either WSJT-X or FLdigi. So my question is, are there any other settings or adjustments to experiment with on the K3S that might give me more flexibility on audio level sent by USB to the Mac? If not, would using a sound card-type device rather than USB be an alternative way to have more ability to control the level of received audio sent to the computer? > > Thanks and 73, > > Frank K6FOD > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html From ve2pid at videotron.ca Wed May 22 18:58:56 2019 From: ve2pid at videotron.ca (VE2PID) Date: Wed, 22 May 2019 18:58:56 -0400 Subject: [Elecraft] [AX1] Who has the AX1 antenna DX record?

Per Sherwood Engineering data, the noise floor for the K3S is -135 dBm.?? Thus 10 dB above that would be -125 dBm. Now since one can't change noise floor one must use the correct amount of attenuation and RF Gain reduction to attain the -125 dBm target for the no signal band noise. Here's the way I handle that.?? This example, the no signal band noise is S-4 or -103 dBm.? That is determined with the Attn off and RF Gain at max.? Then the difference between my target of -125 dBm and -103 dBm is 22 dB.? Thus I need 10 dB of attenuation and 2 S units of RF Gain reduction.????? Lets take this a bit further.? The no signal band noise, no attenuation and RF Gain at max, is S-8 or -79 dBm.? To attain our target of -125 dBm we need a total of 46 dB of attenuation and RF Gain reduction.? If we choose 15 dB of attenuation then we need 5 S units of RF Gain reduction.?? To easily accomplish this, I switch the radio from the antenna to a dummy load.? Then adjust the RF Gain until the S meter indicates S-5 where 1 S unit is = 6 dB.? Thus with 30 dB of RF Gain reduction the switch in 15 dB of Attenuation I have the required 46 dB or so. Then to the audio.? Here I adjust the Recording Gain of the Windows mixer.? Normally this level is about -10 dB or 24% which ever you choose to display the value.??? If the signal level on the WSJT-X is above 30 dB then you should reduce the Windows mixer level a bit more to bring it into ideal range. There is a caution in the K3S manual regarding advancing the K3S Line Output level which could cause distortion.? The default value is 10. As to using AGC, on or off, from the WSJT-X help file: ? "/Use the receiver gain controls and/or the computer?s audio mixer controls to set the background noise level (scale at lower left of main window) to around 30 dB when no signals are present. It is usually best to turn AGC off or reduce the RF gain control to minimize AGC action./" I find using my method for setting the receiver gain based on band noise, and the use of slow AGC will prevent any likely overload of the K3S audio path, the computer audio path, or the WSJT-X software processing. The receiver setting of gain values works quite well for other modes as well.??? But? today I hear hams say; "gotta have more gain to hear those weak signals".?? Yep, 50 years ago this was correct, but not with today's receivers. In looking at the Sherwood Engineering Test data 05/10/2019, the K3S has the lowest noise floor of any others at -135 dBm, it has the best sensitivity of any others at 0.27 uV, and it has the best 100 kHz blocking range of any others at 150 dB.?? The point being.......you have a darn great receiver in front of you.? Now tweak its user parameters to obtain optimum performance which it is capable of providing. Now for those that say "well I heard........" or that "someone told me......."? I say go research for yourself and learn the real facts. 73 Bob, K4TAX From jimithy66 at gmail.com Wed May 22 19:59:48 2019 From: jimithy66 at gmail.com (Jimithy66) Date: Wed, 22 May 2019 19:59:48 -0400 Subject: [Elecraft] K2 PLL Ref.

See the page 40, 41 of the manual here: https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740164%20KX3%20Kit%20Assembly%20Manual.pdf 5. Clean the pins in PCB with isopropylalcohol and blow out dust residues in connectors on the flex cable 6. Re-seat/instal the flex cable back to KX3 carefully. Be sure that the ribbon cable is oriented with the long tab toward the speaker and all pins are engaged when you will put it back to your radio. See Fig.61 on Page 41 of the manual here: https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740164%20KX3%20Kit%20Assembly%20Manual.pdf 7. Check again that flex cable seats well fully engaged and there is nothing forgoten inside of KX3. 8. Close the top and bottom covers of your KX3 carefully and secure them with thumb screws. CAUTION: As you close the covers ensure that the flex cable folds into the space next to the CP board connector as shown. Do not allow it to fold toward the battery holders. If the flex cable resists pushing into the space next to the CP board connector, use your finger to gently crease it along the edge of the connector as shown in Figure 61 of the manual. 9.

Even when the superhet module is in use, the panadapter(s) will still be in direct-sampling mode. The resulting I/Q stream could be used for this purpose.

Message-ID: "> Can the superhet option be switched in/out independently for each of the K4D receivers? In theory." Why is this theoretical? My interest in the question is for use with WSJT-X modes where I currently use a 4 kHz - 5 kHz RX bandwidth. My understanding of the superhet spec is that it would be limited to about 2.8 kHz bandwidth. What is the max bandwidth of the superhet module and, if limited to 2.8 kHz, can it be switch out of circuit?

On April 8th, I sent my K2 transceiver kit to Elecraft, to look at an issue I was having. On April 10th, (2 days later) Elecraft received my K2. I know this NOT because I was notified, but because I researched the tracking number. On May 7th, (29 days later), Elecraft cashed my deposit check that was sent with the K2.

When I was doing repairs for the classic gear, I did not have a staff (like they do in Watsonville) to send emails when the rig arrives, etc. I would email customers when I started work on it, ask any questions about what the customer wanted when the RSA form was incomplete. and let the customer know if there were significant delays. Then when I finish with it, I would send the report to the office and the sales staff would contact the customer about payment. It is tough to keep up with emails, repairs and everything else when there is a backlog of repairs. So working with a staff of one (me) it is difficult to keep up with customer communications in addition to providing prompt repair service. I was not a contract person, but a part time employee of Elecraft. I am certain Dave WFGU (who took over for me, and is also a part-time employee) is having similar problems. In additions, he also works for his Fire Department which has him at the station full time for stretches between 2 and 4 days at a time, and he may not know that his XYL got a repair package in during those days. I know he is currently on vacation and away from home - so any repair parcels are being held for him at the post office or UPS. Sorry that we cannot provide the same level of communications that are available out of Watsonville, but we do the best we can. I had an advantage over Dave because I was not working a full time job when I was doing that legacy repair work. Some patience and understanding is required, and your tracking numbers can be relied on - I never found them to be wrong. Do not send an advance check with your RSA repair. If a check is discovered, it must be sent to Watsonville, and will not be cashed until the repair is concluded. Also, do not send your classic gear to Watsonville, send it as indicated in the RSA instructions. If you do send it to Watsonville, expect an extra week delay because it must then be shipped to Michigan. The newer (non-thru-hole gear) IS serviced at Watsonville, but NOT the classic gear. 73, Don W3FPR On 5/23/2019 1:56 PM, Doug Hensley wrote: > Don, I think that is because the early stuff is farmed out to contract people who may not have an email routine going yet.

Above and beyond that (and equally important), you should pay attention to the Firmware Release Notes. They are on the website and also included on the K3 Utility Help Tab. Those Firmware Release changes also constitute changes/additions to whatever level manual you have. So if you mark up you manual starting with each firmware release after the date in the manual, you will have all the information in the manual. I don't think it is practical for Elecraft to issue a new manual with each firmware release. 73, Don W3FPR On 5/23/2019 3:55 PM, N4ZR wrote: > One of the nice things about Elecraft gear is the continuous improvement > that goes on, even years after initial release.?

As it is, the release notes are shown in the Help tab. But many do not update firmware each time it is available, so it is necessary to review the firmware release notes between what was previously loaded in the K3 and the current level loaded. One can download and print the entire list of firmware release notes or part of the list. They are in .rtf format. 73, Don W3FPR On 5/23/2019 4:48 PM, Jim Brown wrote: > On 5/23/2019 1:23 PM, N4ZR wrote: >> Hi Don - I know I can download a fresh manual, and it may yet come to >> that.?

I don't have a separate multi-band antenna that I can dedicate to the SDRPlay, so I think I need to go the IF Route. I run full legal-limit TX power from antennas in the center of a small city lot, so even if I put up a separate RX-only antenna, I would probably risk damaging the SDR, and also it would not be able to hear the weak signals that my tower-mounted Yagis are picking up and supplying to my K3s. I then need to feed the SDR output into CW Skimmer so I can populate my own bandmaps in N1MM and DX Lab Suite. Has anybody successfully done this, and if so, is there a step-by-step tutorial somewhere that I can reference? Or conversely, if someone wouldn't mind taking a few minutes to walk me through this I'd be extremely grateful. I'm getting precisely nowhere at the moment. --------------------------------------------- 73 and Good DX Peter, W2IRT President, North Jersey DX Association DXCC Card Checker Letter O Manager, ARRL Incoming 2nd District QSL bureau From jim at audiosystemsgroup.com Thu May 23 17:40:27 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 23 May 2019 14:40:27 -0700 Subject: [Elecraft] K3 manual errata In-Reply-To: References: Message-ID: <74f49b13-5d60-272f-ddc8-56d3d534193f@audiosystemsgroup.com> Not at all.?

One time having a question about my new KPA1500 I sent a query via email, it was 15 minutes later that the phone rang from one of the tech support folks. You can not beat that.

As Don, W3FPR pointed out, Don was and I am a part time employee. For a whole host of reasons, that I won't go into at this time, the transition has been somewhat slow but I am making progress. The amount of backlog has been overwhelming to an extent. But with Don's help we have managed to whittle much of it down. I am not making excuses for the lack of communication and will improve my response as I work through this transition. Poor Don is supposed to be retired and still provides excellent support in my absence or heavy workload. As he noted, my wife and I are on vacation well off of the grid. I do have some wifi here (sitting at the Tiki bar as I write this) but I am pretty much off the grid until next week. I do totally love the Elecraft customer service paradigm and will continue to strive for that plateau. But it will take me a little time as I still work a fulltime profession as well as this part time venture plus family blah blah blah.

The amount of backlog has been overwhelming to an extent. But with Don's help we have managed to whittle much of it down. I am not making excuses for the lack of communication and will improve my response as I work through this transition. Poor Don is supposed to be retired and still provides excellent support in my absence or heavy workload. As he noted, my wife and I are on vacation well off of the grid.

I do totally love the Elecraft customer service paradigm and will continue to strive for that plateau. But it will take me a little time as I still work a fulltime profession as well as this part time venture plus family blah blah blah.

When I was doing repairs for the classic gear, I did not have a staff (like they do in Watsonville) to send emails when the rig arrives, etc. I would email customers when I started work on it, ask any questions about what the customer wanted when the RSA form was incomplete. and let the customer know if there were significant delays. Then when I finish with it, I would send the report to the office and the sales staff would contact the customer about payment. It is tough to keep up with emails, repairs and everything else when there is a backlog of repairs. So working with a staff of one (me) it is difficult to keep up with customer communications in addition to providing prompt repair service. I was not a contract person, but a part time employee of Elecraft. I am certain Dave WFGU (who took over for me, and is also a part-time employee) is having similar problems. In additions, he also works for his Fire Department which has him at the station full time for stretches between 2 and 4 days at a time, and he may not know that his XYL got a repair package in during those days. I know he is currently on vacation and away from home - so any repair parcels are being held for him at the post office or UPS. Sorry that we cannot provide the same level of communications that are available out of Watsonville, but we do the best we can. I had an advantage over Dave because I was not working a full time job when I was doing that legacy repair work. Some patience and understanding is required, and your tracking numbers can be relied on - I never found them to be wrong. Do not send an advance check with your RSA repair. If a check is discovered, it must be sent to Watsonville, and will not be cashed until the repair is concluded. Also, do not send your classic gear to Watsonville, send it as indicated in the RSA instructions. If you do send it to Watsonville, expect an extra week delay because it must then be shipped to Michigan. The newer (non-thru-hole gear) IS serviced at Watsonville, but NOT the classic gear. 73, Don W3FPR On 5/23/2019 1:56 PM, Doug Hensley wrote: Don, I think that is because the early stuff is farmed out to contract people who may not have an email routine going yet.

I could put in an antenna switch, but honestly I'd rather not unless there's no alternative. I only need the CW portion of the currently active band to feed the SDR--but I agree, having full bandwidth would be better. I am also considering Win4K3 Suite, but I'm not sure about how to get this to work with the K3s, DX Lab Suite, and N1MM+. It's a real nightmare to understand if you don't really have much understanding of how it all works. - pjd -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Ignacy Sent: Thursday, May 23, 2019 7:20 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer Connecting SDR may be simpler.

I have found it really easy to control anything you want or have so long as it is compatible with the K3. It's all done using virtual com ports that you create using a FREE bit of software named com0com. You create the ports in pairs and name them com10, com11, etc. One com port is listed in the Win4K3 set up and the other is called out in the software you want to connect. I use about 6 pairs with no problems and it seems to be very stable. Listen for me this weekend as I will be using this set up for the CQ WPX contest with N1MM as my logging package. Getting CW Skimmer to work with SDRPlay is quite convoluted, so I use LP Pan to an external sound card to drive Skimmer with the required MME format data; I had the LP Pan left over from something else I was doing. You will dedicate a comport pair to Skimmer so it integrates and plays with everything else. I have played with a few different configurations and feel comfortable that this is the easiest way to go and it yields great flexibility with stability. Best of Luck. 73, Barry K3NDM ------ Original Message ------ From: "Peter Dougherty" To: "Ignacy" ; elecraft at mailman.qth.net Sent: 5/23/2019 7:57:31 PM Subject: Re: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer >I have the same front end protector on my K9AY receive loop, but that's not >a suitable antenna for anything above 80m, and I need the SDR to be >functional on all bands.

I am a new Elecraft owner... 2 k3s and a k3,and kpa1500. I bought the k3 used off of Ebay,and it had a problem. Elecraft emailed me when they received it,gave me prices,and told me it would be about 3 weeks. I was happy. Then the next day,I received an email telling me that they had fixed one problem,and found another. I said ok,fix it,and within 3 days it was done,and back in a box. That was super fast,and the radio works great. Rob in tech support has been helping me since the start. He is fantastic.

In fact I did that initially, I now use a Minicircuits Lab 2 way splitter and an about 6 db gain buffer amp between my K3s and the divider. This seemed to give me a bit better spectrum display. You will need NO SDR protection as you are using the receiver IF. I did use HDSDR during one of my early configurations. It just seemed harder to set up than what I use now. But, it won't require spending for an LP pan and sound card. Hmmm. I think I just got the answer to a question I had raised about using the I&Q data available from the K4 USB connector for CW Skimmer. I suspect the formats are the same. Your description at the bottom of your note will work if all you want is spectrum display, but to do serious integration like marrying up logging, spotting spectrum display CW skimmer and then a contest configuration, you are going to need to distribute and receive K3 band, frequency, and mode data. Using Win4K3 suite with com0com does make that easy and you could use what you describe using a pair of virtual ports. Should work well. 73, Barry K3NDM ------ Original Message ------ From: "Bob McGraw K4TAX" To: elecraft at mailman.qth.net Sent: 5/23/2019 8:36:06 PM Subject: Re: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer >Why not take the RX OUT of the K3 to a BNC T and the RX IN of the K3 to the other side of the BNC T and with a BNC T in that path, feed that to the SDR receiver.

Since I built K2-90X, I have had many conversations with the folks at Elecraft. Don has helped me with the many K2?s I have had over the years (10?) and now realize that I should keep the one that is here now, a K2/100 that Don calibrated as probably one of his last ones before he handed the batton over. Some of the questions and service I have asked for over the years was well over the top, one example was a KX3 that should have been discarded after lightning hit it (not my QTH, the guy I got it from) I believe Howard worked on that one for several (4?) hours. I got it back in perfect shape! I know he wasn?t happy with the condition of the radio but he kept working on it until it was done. (I put the same amount of effort in my business, of which I have owned now for 30+ years.) Each time, Elecraft excelled to the top helping me every step of the way. I got to know some of the early support folks quite well over the years. Recently I got a used K3 that needed some set-up done. One of the Techs walked me through for about an hour before we both realized that I really needed the USB cable to take it the next level. Got that from them two days later, and I got a call from the Tech ?to continue? until it was perfect. I am just thrilled with it now. Elecraft is number one here and they earned that place. My arsenal consists of a K1, K2, KX3 and now a K3. (Yeah there are some Collins here as well as a recent KWM-380 that I just got running but Elecraft is the radio that is ?always on?. Yes I do have some other gear non-Elecraft gear but like Microsoft, I look at that equipment with an eye that I will never get that level of support from the others. It took me many calls and a few mis-orders to get a clip for my 857 for example. I hope that we continue to see the consistent service that has made Elecraft Number One in my eyes.

Currently the K3 documentation is confused at best.? According to the release notes, the latest MCU is 4.77, but my radio was back to the factory early this year, and it now reports an installed MCU version of 5.66.? Oddly, though, the K3 Utility says that 4.67 is still the latest available.? There are similar discontinuities in the FPF and DSP firmware. So I have absolutely no idea what's changed in my radio. 73, Pete N4ZR Check out the Reverse Beacon Network at , now spotting RTTY activity worldwide.

Your description at the bottom of your note will work if all you want is spectrum display, but to do serious integration like marrying up logging, spotting spectrum display CW skimmer and then a contest configuration, you are going to need to distribute and receive K3 band, frequency, and mode data. Using Win4K3 suite with com0com does make that easy and you could use what you describe using a pair of virtual ports.

You should use IF out. You need not disconnect your receive antenna. I believe there is a buffer between the receiver IF and the connector on the back of the K3, but the splitter adds a little over 3 db loss/per output. The buffer amp I added, the Clifton Lab amp available from DX Engineering, adds little better buffering and just enough additional gain to make up for the losses caused by the splitter. You loose NO coverage this way. You really do want to use the Win4K3 suite all the time. It will be the center for all of your radio to various software communications even if you never use the built in features. Please do not stress over setting up com ports; it really isn't that hard with a port replicator like com0com. There is only one port to worry about, the one real one that connects to the radio. You can make that anything you like using device manager, but just use whatever your computer calls it. To find out what that is just bring up device manger, look under ports. You should see a list of com ports. If there is nothing there, you probably have only USB ports. If this is the case plug in your USB to serial adapter. It will show up as a com port with number. That is what your radio will use and you will tell Win4K3 that number. The virtual comports you create will remain constant; just write them down so you don't forget them and the pairing. Win4K3 communicates through these virtual ports, and they will not change. The one real one may change due to software upgrades, but it can be changed back in device manager. Now you cab connect any software package you want and use a virtual com port. If you use logging software, use the same com port as you would for your contest logger like N1MM. Since you will use one or the other, your logging can alsways be on that com port; this keeps a constant plan no matter what you do. And I do the same thing with FLDIGI and WSJT-X. My point is pick some com port designators and some configuration plan. You can also use this plan with onmirig and whatever you want. Hopefully, this whole thing helps. 73, Barry K3NDM ------ Original Message ------ From: "Peter Dougherty" To: "Barry" ; "Bob McGraw K4TAX" ; elecraft at mailman.qth.net Sent: 5/23/2019 10:00:14 PM Subject: RE: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer >I had an LP-PAN and sound card and could never get them to work very well >(they're up for sale for anybody who's interested).

The hfwnotes.rft has every update from the first to the latest firmware updates. My career as as broadcast engineer I had developed a habit keeping all modifications with instruction books. My procedure is to copy the latest changes to a paper page and then add that page to a notebook labeled FW Notes K3. I have done the same for the rest of my K-Line and KX3/KXPA. When I load new firmware (usually the beta versions), I replace the hfwnotes.rft with the latest version to also have a searchable version. I keep telling myself that I will print the latest K3 IB and make all the changes by hand; but somehow retirement has left me too little time.

Oddly, though, the K3 Utility says that 4.67 is still the latest available. There are similar discontinuities in the FPF and DSP firmware.

There's a paradigm shift going on in transceiver design, and we reached a point where we needed to embrace it. This shift is not entirely aligned with accessibility, as you know. I'll address alternatives in this email. As for the K4 specifically, its user interface is dependent in part on use of the touch screen. This was simply the only way to integrate an equivalent of the K3S, P3, and all of the new hardware/software required to implement a direct-sampling radio. The use of a touch screen allows context sensitivity (physical overloading) for controls, making the K4 the equivalent of a much larger radio without touch. The resulting compact size is still compatible with portable use (4.5" x 13.5" x 11", 10 pounds, and power-efficient), a hallmark of Elecraft transceivers. Regarding accessibility, there are three possible approaches: 1. The K4's entire complement of controls, both hard and touch, will be represented by a set of "2-letter" commands. This API will be fully public as it is for our other transceivers. Presumably external devices or computers will be able to immediately make use of these commands to effect a flexible accessible interface. 2. In theory we could implement a large-target version of the LCD's touch controls, with proximity-based audio feedback and no panadapter. This would be a very ambitious project requiring ongoing support, similar to that needed for mobile/fixed app development. We don't have the staff to support this, so we'd need to engage the wider community to find a developer with suitable skills and motivation. The API or spec for such an effort doesn't exist at this time. 3. The K3S has very similar strong-signal performance and similar basic features, without touch. Since many of the added features of the K4 are panadapter-centric, a blind ham may very well find that the K3S is a viable alternative. No doubt there will be more used K3's and K3S's on the market over the next year. The KX3 and KX2 provide audio CW feedback on most controls and are another non-touch alternative. I hope the alternatives I've suggested to use of the K4's normal UI will be helpful in most cases. 73, Wayne N6KR > On May 24, 2019, at 9:20 AM, Buddy Brannan buddy at brannan.name [KX3] wrote: > > [Sorry, sent this to Gary instead of the list] > Hey Gary, > > I?m curious about this as well, as are others?see K8HSY?s post on the blind-hams list.

I?ve found it?s important to remove the transverter?s top cover to do this ? because it is possible when pushing cables into the female connectors blind, even being careful, to actually bend back the business end of the sockets. I don?t remember off hand which two it is, but I?ve had enough problems with them that I now support them from the rear with a screwdriver blade when seating cables to ensure a solid connection. Otherwise, it sounds offhand like there?s something bad on the transverter board ?

I appreciate your forthrightness on this issue and willingness to tackle the more difficult questions/aspects/design decision justifications. Elecraft has, as I stated in my original email, always been supportive of the blind ham community inasmuch as design limitations and parameters allow, and I for one appreciate your continuing commitment to that. Computer control couldn?t be simpler on the Elecraft rigs I own. The Hampod is also a fantastic accessory, and we appreciate your working with the developers of these aids. I suspect that, were I able to get a higher end rig, I?d be opting for a K3 for the exact reasons you specify. But I?m a knob and button kind of guy. I think, were I interested in going whole hog for a K4, that your option (1) seems to be the most straightforward path, certainly in the short term, to get the mostbang for our accessibility buck, as it were. There?s lots of flexibility there. I?m not sure what the state of the art is for touch screen accessibility under GNU/Linux. I know there is a GNOME-based screen reader, as well as an Android-based screen reader. Given the right clever people, it might be possible to have an alternative UI, but, as you say, that would be a pretty significant support issue for a pretty small market of users. But one could potentially duplicate those controls on, say, an Amazon Fire or Android tablet app. I think there really are possibilities for the right clever people?shame I?m not one such. Again, I appreciate that Elecraft at least considers these issues, which is more than I can say for many, many other companies.

This was simply the only way to integrate an equivalent of the K3S, P3, and all of the new hardware/software required to implement a direct-sampling radio. The use of a touch screen allows context sensitivity (physical overloading) for controls, making the K4 the equivalent of a much larger radio without touch. The resulting compact size is still compatible with portable use (4.5" x 13.5" x 11", 10 pounds, and power-efficient), a hallmark of Elecraft transceivers. > > Regarding accessibility, there are three possible approaches: > > 1. The K4's entire complement of controls, both hard and touch, will be represented by a set of "2-letter" commands. This API will be fully public as it is for our other transceivers. Presumably external devices or computers will be able to immediately make use of these commands to effect a flexible accessible interface. > > 2. In theory we could implement a large-target version of the LCD's touch controls, with proximity-based audio feedback and no panadapter. This would be a very ambitious project requiring ongoing support, similar to that needed for mobile/fixed app development. We don't have the staff to support this, so we'd need to engage the wider community to find a developer with suitable skills and motivation. The API or spec for such an effort doesn't exist at this time. > > 3. The K3S has very similar strong-signal performance and similar basic features, without touch. Since many of the added features of the K4 are panadapter-centric, a blind ham may very well find that the K3S is a viable alternative. No doubt there will be more used K3's and K3S's on the market over the next year. The KX3 and KX2 provide audio CW feedback on most controls and are another non-touch alternative. > > I hope the alternatives I've suggested to use of the K4's normal UI will be helpful in most cases. > > 73, > Wayne > N6KR > > > > >> On May 24, 2019, at 9:20 AM, Buddy Brannan buddy at brannan.name [KX3] wrote: >> >> [Sorry, sent this to Gary instead of the list] >> Hey Gary, >> >> I?m curious about this as well, as are others?see K8HSY?s post on the blind-hams list.

My KPA1500 died (I think they had a bad run on capacitors because others have reported the same thing to me via email) and I emailed the list here on a Sunday. Eric immediately asked for logs to be sent to support. Now I've had odd email problems with Elecraft in the past. At the very least I've never seen a firmware update email so I called Elecraft in the middle of Monday when I didn't see a reply. What I got was a call back late in the day where the support person (I can't remember who) was reading me the riot act about not responding immediately to "the CEO". Soon afterwards, the support person found my email in their spam folder. It turned out OK, but I'm still uncertain why they had me try a different cable, then take the cover off and measure voltages. I'm perfectly capable, but the KPA1500 isn't a kit. In the end my amp works fine. UPS was really inexpensive for shipping. The only odd part was the interaction with support, and how long it took to debug before they asked me to ship it down. I'm happy with Elecraft, but the interaction with support was a little odd.

Try FM on HF with someone close and see if if it is really caused by the K144 Does the K144 output also drops or is that stable. 73 Henk PA0C Verzonden vanaf mijn Samsung Galaxy-smartphone. -------- Oorspronkelijk bericht -------- Van: Nr4c Datum: 23-05-19 19:32 (GMT+01:00) Aan: Hank Cc: Hank Blackwood , Elecraft Reflector Onderwerp: Re: [Elecraft] K144XV issues in K3S Frequency drift comes to mind.The HF ATU probably won't do anything for VHF.Let the radio warm up for half an hour before doing anything with VHF.Remember 1PPM at VHF is 144 Hertz.You need the high def oscillator and maybe the Ref In.Sent from my iPhone...nr4c. bill> On May 23, 2019, at 1:05 PM, Hank wrote:>>> Hey Folks... ?>> I have noticed 2 unusual issues with my recently installed K144XV. ?I bought it used from a list member and installed it a few months ago. ?It seems to work ok but after some extended use (which recently begun) it is does 2 things: after it has been in use (even just monitoring) for local FM repeater work, the S-Meter on the K3S starts to read lower and lower (by as much as 3 S-Units) for the same repeater signal; and 2 - the audio becomes a little distorted on stronger signals (the ATT makes no difference in the audio distortion).>> The audio happens almost immediately after turning up the rig, but the signal "weakening" takes 10 to 15 minutes of the transverter being active (active band on K3S). ?It will occur faster it is being used (transmitting). ?I have it set to very low power (display reads -6db), and it will still show "weakening" on the S-Meter during reception after using it. ?I noticed it fist doing some longer packet transmissions, but it will also happen after a period of time of just listening.>> The audio distortion is not as noticeable on signals below S-9, but listening in headphones will reveal the distortion is still there.>>> The K3S currently has the standard TXCO installed and no reference lock on the K144XV. ?The 13khz filter is installed in the main receiver. ?I have no external reference board installed in the K3S. ?I have ordered the higher stability TXCO for the K3S and the K144XV reference lock, but have not received them yet from Elecraft.>>> The audio on HF is OK and the S-Meter does not seem to "weaken" in a similar fashion when monitoring strong net signals over time.>>> Any ideas?>> Hank> K4HYJ> K3S, P3, KX3>>>>>>>> ______________________________________________________________> Elecraft mailing list> Home: http://mailman.qth.net/mailman/listinfo/elecraft> Help: http://mailman.qth.net/mmfaq.htm> Post: mailto:Elecraft at mailman.qth.net>> This list hosted by: http://www.qsl.net> Please help support this email list: http://www.qsl.net/donate.html______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html From ghyoungman at gmail.com Fri May 24 16:04:00 2019 From: ghyoungman at gmail.com (Grant Youngman) Date: Fri, 24 May 2019 16:04:00 -0400 Subject: [Elecraft] Elecraft Customer Service - Outstanding In-Reply-To: References: <0FDA957D-C09B-4DFF-AAF3-14357E31BFDF@icloud.com> Message-ID: <5568FDC7-9DF3-4B71-8CF9-33A1794E36BF@gmail.com> Since on at least one occasion your unanswered email was discovered in Elecraft?s spam folder, it?s possible your email domain is being flagged for some reason by whatever mail host/service/application is being used at Elecraft.

I appreciate your forthrightness on this issue and willingness to tackle the more difficult questions/aspects/design decision justifications. Elecraft has, as I stated in my original email, always been supportive of the blind ham community inasmuch as design limitations and parameters allow, and I for one appreciate your continuing commitment to that. Computer control couldn?t be simpler on the Elecraft rigs I own. The Hampod is also a fantastic accessory, and we appreciate your working with the developers of these aids. I suspect that, were I able to get a higher end rig, I?d be opting for a K3 for the exact reasons you specify. But I?m a knob and button kind of guy. I think, were I interested in going whole hog for a K4, that your option (1) seems to be the most straightforward path, certainly in the short term, to get the mostbang for our accessibility buck, as it were. There?s lots of flexibility there. I?m not sure what the state of the art is for touch screen accessibility under GNU/Linux. I know there is a GNOME-based screen reader, as well as an Android-based screen reader. Given the right clever people, it might be possible to have an alternative UI, but, as you say, that would be a pretty significant support issue for a pretty small market of users. But one could potentially duplicate those controls on, say, an Amazon Fire or Android tablet app. I think there really are possibilities for the right clever people?shame I?m not one such. Again, I appreciate that Elecraft at least considers these issues, which is more than I can say for many, many other companies.

This was simply the only way to integrate an equivalent of the K3S, P3, and all of the new hardware/software required to implement a direct-sampling radio.

Without it, I would be chasing the K3 with a mouse via HRD (mouse or K-Pod sits on the edge of my desk within easy reach).? I prefer to run without being tethered to a computer. A few extra buttons on the K-Pod would be great, but it is what it is and I appreciate it for what it is. A suggestion for the touch-screen users out there (IC-7300 and Fire Tablet in my station) is to use a stylus. Very accurate and does not crud up the screen.

Recent Google Android phones do a decent job of voice recognition on the phone itself with no connection to the internet or cloud voice recogniton servers. There are open source voice recognition software applications that run on Linux. No idea how powerful the K4 processor is or how capable it might be to do this, but I'm throwing the idea out there. 73, Mark W7MLG From srmuenich at gmail.com Fri May 24 17:53:09 2019 From: srmuenich at gmail.com (Steve Muenich) Date: Fri, 24 May 2019 16:53:09 -0500 Subject: [Elecraft] FS: K3S w K-Pod Message-ID: <3B944E99-CA55-46BB-B3B9-B858AC87DDDF@gmail.com> I am selling my K3S with extras It includes: KPA3A 100 watt amp KAT3A ATU KXV3A IF in/out 2nd Receiver KIO3B USB audio in/out Both Main RX and Sub RX have same filters in each 2 each KFL3A-2.7K (2.7khz, matched pair) 2 each KFL3A-400-IR (inrad filters, 400 hz, 8 pole) 2 each KFL3A-200 (200 hz, 5 pole, matched pair) standard 5ppm oscillator K-POD Never has been to factory, never have had any issues.

I believe the S/N was around 4K? It was back in the day when almost every DXpedition was using K3's so it was obviously the radio to own. (Around 2009?) It was at the top of the Sherwood ratings. Owner's bragged, incessantly, about its Sherwood rating. After a period of time I grew to really dislike that radio. The audio was just plain awful and the man/machine interface was the worst I have ever seen. I detest bar graphs. I suppose if you play at ham radio 8 hours a day, seven days a week, the interface is "normal", even usable. For those of us who might get on the air for an hour or two a week, the controls were a mystery. Tap this button to do this, hold the same button for three seconds to do that, the list goes on. NOTHING was intuitive. It did not help that it was an incredibly ugly, too light and unsubstantial, radio. It's looks may have been barely acceptable when first introduced but it aged badly, rapidly. Over a ten year period it's price has become a real problem. There were many, many questions on this reflector regarding the controls, the same questions about the same controls, over and over and over again. That should have been a very large hint that the controls should be massively improved in any new radio. I sold my K3 and moved on to the big Japanese three, ANAN, and Flex, over the years. All had many, fairly easy to understand, controls. All were far, far more usable than the K3. Both the ANAN and Flex service departments are as good as Elecraft's. Eventually I left the Elecraft reflector, and that is a whole other story..... Last week the K4 was announced so I rejoined the reflector. It sounded like a really great radio. Sadly, I have concluded it will be a dud, mostly because it is designed with the same philosophy as the K3 was, a small, compact, easily transportable radio, "a hallmark of Elecraft transceivers", to quote you, Wayne. From all that I have read, the controls will be even more complex. Ham radio operators are an aging group. Some suffer from the "fat finger" syndrome, others have vision problems, to name just two. The last thing they need or want is a tiny radio with minimal controls, each of which serves two or three or four or five purposes. They favor a radio that has many single or dual purpose knobs. They want bigger screens, the K4 screens are too small. I suggest you double the size of the radio and change your design criteria. Enlarging the physical size would not be a huge cost driver. Remember who your customers are. And when the Flex 6700 kicked the K3 out of first place in the Sherwood ratings in 2014, the Koolaid drinkers on this reflector were heard to say, "People put too much faith in numbers". Hypocrisy is thy name. I haven't stopped laughing. This email pertains to only the second and third paragraphs of Wayne's reply below. I wish Elecraft well with the K4 but I really think your minimalist/too complex way of designing needs to change. You've probably already guessed that I won't be a customer of the K4 as currently proposed. And you really, really ought to improve this reflector........... 73, Harry K1RSA -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Wayne Burdick Sent: Friday, May 24, 2019 2:03 PM To: Elecraft Reflector ; KX3 at yahoogroups.com; Elecraft-K4 at groups.io Subject: [Elecraft] Elecraft K4 and Accessibility Hi Buddy et al, We've definitely been thinking about this. There's a paradigm shift going on in transceiver design, and we reached a point where we needed to embrace it. This shift is not entirely aligned with accessibility, as you know. I'll address alternatives in this email. As for the K4 specifically, its user interface is dependent in part on use of the touch screen. This was simply the only way to integrate an equivalent of the K3S, P3, and all of the new hardware/software required to implement a direct-sampling radio. The use of a touch screen allows context sensitivity (physical overloading) for controls, making the K4 the equivalent of a much larger radio without touch. The resulting compact size is still compatible with portable use (4.5" x 13.5" x 11", 10 pounds, and power-efficient), a hallmark of Elecraft transceivers. Regarding accessibility, there are three possible approaches: 1. The K4's entire complement of controls, both hard and touch, will be represented by a set of "2-letter" commands. This API will be fully public as it is for our other transceivers. Presumably external devices or computers will be able to immediately make use of these commands to effect a flexible accessible interface. 2. In theory we could implement a large-target version of the LCD's touch controls, with proximity-based audio feedback and no panadapter. This would be a very ambitious project requiring ongoing support, similar to that needed for mobile/fixed app development. We don't have the staff to support this, so we'd need to engage the wider community to find a developer with suitable skills and motivation. The API or spec for such an effort doesn't exist at this time. 3. The K3S has very similar strong-signal performance and similar basic features, without touch. Since many of the added features of the K4 are panadapter-centric, a blind ham may very well find that the K3S is a viable alternative. No doubt there will be more used K3's and K3S's on the market over the next year. The KX3 and KX2 provide audio CW feedback on most controls and are another non-touch alternative. I hope the alternatives I've suggested to use of the K4's normal UI will be helpful in most cases. 73, Wayne N6KR > On May 24, 2019, at 9:20 AM, Buddy Brannan buddy at brannan.name [KX3] wrote: > > [Sorry, sent this to Gary instead of the list] Hey Gary, > > I?m curious about this as well, as are others?see K8HSY?s post on the blind-hams list.

I respect your right to an opinion and right to vote with your dollars. You represent a market segment that Elecraft May or may not choose to address. It?s Wayne and Eric?s strategy to decide. I for one may represent a different (slightly) younger market segment and I have been drawn to the Elecraft UI and design philosophy. I create computer based products, although mostly software these days and I think Wayne and the development team are spot on. To me, the Elecraft menus just ?feel right? compared to the Japanese approach. There?s lots of room for different market segments in this hobby. Everyone should vote with there dollars. Eric, Wayne and the whole team should be mindful of all feedback, but be respectful of their their choices (and others tastes). let?s not come on the Elecraft reflector to troll Elecraft design. It?s not cool to call someone?s kid ugly.

We don't have the staff to support this, so we'd need to engage the wider community to find a developer with suitable skills and motivation. The API or spec for such an effort doesn't exist at this time. 3. The K3S has very similar strong-signal performance and similar basic features, without touch. Since many of the added features of the K4 are panadapter-centric, a blind ham may very well find that the K3S is a viable alternative. No doubt there will be more used K3's and K3S's on the market over the next year. The KX3 and KX2 provide audio CW feedback on most controls and are another non-touch alternative. I hope the alternatives I've suggested to use of the K4's normal UI will be helpful in most cases. 73, Wayne N6KR > On May 24, 2019, at 9:20 AM, Buddy Brannan buddy at brannan.name [KX3] wrote: > > [Sorry, sent this to Gary instead of the list] Hey Gary, > > I?m curious about this as well, as are others?see K8HSY?s post on the blind-hams list.

From all that I have read, the controls will be even more complex. The K4's controls are actually quite a bit simpler, and more intuitive, thanks to the new display. We were limited to a small display with fixed segments in the K3/K3S, which constrained the ways we could provide visual feedback. Also, as the years went by, we added many new features that, in turn, were constrained by the existing switches/knobs/display. This evolution may not have been ideal from a UI standpoint, but it provided our customers with features they wanted, without the need to continually buy a new radio. We accepted a long time ago that we can't please everyone or satisfy every ergonomic requirement. Our business was forged at Field Day, so portability will remain a high priority. Lifting or carrying a K4 won't hurt aging backs. We (and hundreds who tried the radio at Dayton, expressing delight at the new front panel) feel that the K4's UI is not just a significant advance over the K3/K3S, but also over most other transceivers in its class, regardless of their size and weight. I invite you to try the radio in person if you get the chance. 73, Wayne N6KR From rkourey at carolina.rr.com Fri May 24 20:36:40 2019 From: rkourey at carolina.rr.com (Rick Kourey) Date: Fri, 24 May 2019 20:36:40 -0400 Subject: [Elecraft] Location of VFO B on the K4 Message-ID: First, let me say, I have never owned an Elecraft radio or amplifier but I have become interested in the K4 and the KPA1500 amplifier combination. One of the most surprising features on the K4 is VFO B is located at the top right side of the radio. Thus you cannot rest the palm of your hand on the desktop and turn VFO B with ease using your fingers like you can do with the main VFO A. This seems so unnatural to me and I wonder if there is a reason VFO B would be placed in such a high-up location. I am not sure I have ever seen this on competing radios as the smaller VFO B knob always seems to be located next to the main VFO which is near the bottom edge of the radio. Help me understand why this physical design was chosen.

And, in many ways, critical feedback inviting a review of basic design principles is at least as valuable as pages of Q&A about work-arounds and detail; it all has its place. Harsh criticism, respectfully delivered as Harry's was, is not trolling. I'm a happy KPA1500 owner but, as you recognize, not everyone warms to all products from a given manufacturer and, despite close examination of Elecraft transceiver offerings, I made alternative choices, most recently involving a TS-890S (which, by the way, also has the RIT/XIT in the right place!). I look forward to the K4 release and have no doubts it will be a great radio. I may yet vote in that direction but I found the way Elecraft handled the K4 announcement (controlled leak?) baffling and reminiscent of Apple and their fanboys. I recall a thread on the K4 being closed a couple of months ago, only for another sanctioned one to emerge and continue, followed by the dribble of actual news about the K4. It was all just odd, in my view. 73, Peter (VK6HP). -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Rod Hardman Sent: Saturday, 25 May 2019 8:17 AM To: hwhite1 at maine.rr.com Cc: Elecraft Reflector ; KX3 at yahoogroups.com; Elecraft-K4 at groups.io Subject: Re: [Elecraft] Elecraft K4 and Accessibility Harry, you got they the first time.

Which means they were totally shorted. I replaced them with new diodes (which measured 316 forward, and infinite backward), and the RF display is once again working. Unfortunately, I don?t have a dummy load to do the calibration on page 48 right now, so it will probably have to wait a few more days before I can everything in the same place.

I am expecting to buy a new radio next year so good discussion on the K4. I expect to use my current upgraded K3 both at home and in the field, perhaps at a field day event so high dynamic range is good. At home we are out in a rural area so the K4 or K4D will be good. I tend to not use tough screen things but if the touch screen was robust as I read is true for the K4 that might be fine. Comments below...

Also I have waited days for a response. Sometimes having to email a second time. The problem with the email support system is the customer does not know if the email has been received or read. I have suggested on more than one occasion to Eric and Wayne at trade shows they should consider a trouble ticket based system. Then the customer could just log onto the system through a web browser and know the status of his request. At my old place of employment the IT department used this type of system. Both Ham Radio Deluxe and Logic 9 use a form of this system which I have used successfully. Yes there would be some upfront cost but I would venture that it would save the Elecraft support staff time and frustrated customers. Along with the K4 would it be great if the support system was modernized.

From all that I have read, the controls will be even more complex. The K4's controls are actually quite a bit simpler, and more intuitive, thanks to the new display. We were limited to a small display with fixed segments in the K3/K3S, which constrained the ways we could provide visual feedback. Also, as the years went by, we added many new features that, in turn, were constrained by the existing switches/knobs/display. This evolution may not have been ideal from a UI standpoint, but it provided our customers with features they wanted, without the need to continually buy a new radio. We accepted a long time ago that we can't please everyone or satisfy every ergonomic requirement. Our business was forged at Field Day, so portability will remain a high priority. Lifting or carrying a K4 won't hurt aging backs. We (and hundreds who tried the radio at Dayton, expressing delight at the new front panel) feel that the K4's UI is not just a significant advance over the K3/K3S, but also over most other transceivers in its class, regardless of their size and weight. I invite you to try the radio in person if you get the chance. 73, Wayne N6KR --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From ve3hls at gmail.com Sat May 25 09:04:43 2019 From: ve3hls at gmail.com (Kenneth P Alexander) Date: Sat, 25 May 2019 13:04:43 +0000 Subject: [Elecraft] Location of VFO B on the K4 In-Reply-To: References: Message-ID: I'm sure somebody make a custom CNC titanium VFO-B wrist rest...right after they get their 2 lb custom CNC VFO knobs to market! ?

That's been a "typical" location for many years across many radios. Yaesu's FT1000D and FT1000MP Mark V, Ten-Tec Orion, Icom IC-7800, etc. From my perspective, the location in the lower right is more convenient for tuning VFO B (transmit frequency) with dual receive to locate where the DX station is listening in split operations. Granted, with a KPOD, the location of VFO B tuning becomes moot as tuning control is at my fingetrtips. But absent a KPOD, reaching up isn't quite as convenient and you can't rest your wrist on the desk to tune. If I were designing the radio, I'd move the VFO B knob down to the lower right, use a larger knob, put RIT immediately above that, and move the 4 buttons up where the VFO knob is currently located. 73 Lou, W0FK ----- St. Louis, MO "The difference between stupidity and genius is that genius has its limits."

With the KPA100 installed the KAT100 wattmeter is only used to calculate the SWR and use that value to light the SWR bargraph. But otherwise they are electrically equal. Why the KPA100 diodes get zapped while the KAT100 ones are often unscathed is a question I do not have an answer for - it may have something to do with the physical placement of the toroid and the diodes.? The KAT100 has a greater groundplane area around the toroid and diodes, and I believe that has something to do with it. I would suggest that you do something like putting a non-inductive resistor from the KPA100 SO-239 jack to ground to bleed off residual static.? I have used 3 watt 47k resistors successfully for that purpose. While you are at it, put one across each ANT jack in the KAT100 as well - if you have the KAT100-1, you can easily solder them on the bottom of the board - with the KAT100-2, it is not difficult to solder the resistors directly across the SO-239 jacks. 73, Don W3FPR On 5/25/2019 1:24 PM, Bill Coleman wrote: > Don, I have one question. > > This is the second time my K2/100 has completely toasted D16 and D17.

Once I tune to a station that's operating CW split, I press the PF1 button on my K3 to run a macro that turns on the second receiver, sets its bandwidth and enables TX up 1 KHz. My hand then moves to the B VFO control for TX frequency adjustments based on my success vs what I hear the DX send and what I see on the P3. I almost never use RIT. I too would have placed the K4 B VFO knob in a location similar to the K3's. Taking a closer look at the K4, I see four programmable buttons (vs two on the K3). If I were to use PF1 for the same macro as above my hand would already be right there to tune the B VFO. Of course the proof is in the actual experience. I suspect getting use to position of the K4 B VFO control will be quick. Looks like cognitive science at work. 73 - Steve WB6RSE From donwilh at embarqmail.com Sat May 25 13:52:11 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 25 May 2019 13:52:11 -0400 Subject: [Elecraft] [K2] K2/100 RF power indication not working - Blown D16 & D17?

If the KAT100 is connected to a QRP K2 (KPA100 physically removed) through a KIO2, then the KAT100 wattmeter will be used for power control and SWR display in the K2 display. As long as the KPA100 is physically connected, its wattmeter is used for power control and also display of SWR on the K2. 73, Don W3FPR -------------------------------------------------------------------------------------------------------------------- Bill, Both wattmeters (KPA100 and KAT100) are in-line at the same time. With the KPA100 installed the KAT100 wattmeter is only used to calculate the SWR and use that value to light the SWR bargraph. But otherwise they are electrically equal. Why the KPA100 diodes get zapped while the KAT100 ones are often unscathed is a question I do not have an answer for - it may have something to do with the physical placement of the toroid and the diodes.? The KAT100 has a greater groundplane area around the toroid and diodes, and I believe that has something to do with it. I would suggest that you do something like putting a non-inductive resistor from the KPA100 SO-239 jack to ground to bleed off residual static.? I have used 3 watt 47k resistors successfully for that purpose. While you are at it, put one across each ANT jack in the KAT100 as well - if you have the KAT100-1, you can easily solder them on the bottom of the board - with the KAT100-2, it is not difficult to solder the resistors directly across the SO-239 jacks. 73, Don W3FPR On 5/25/2019 1:24 PM, Bill Coleman wrote: > Don, I have one question. > > This is the second time my K2/100 has completely toasted D16 and D17. > I also have a KAT100 connected at the same time, which has virtually > identical SWR bridge. > > How is it that a static discharge can destroy D16 and D17, but the > diodes D1 and D2 in the KAT100 are unaffected? > > With the K2/100 / KAT100 combo, at which time are each of the SWR > bridges used? > > From donwilh at embarqmail.com Sat May 25 14:08:51 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 25 May 2019 14:08:51 -0400 Subject: [Elecraft] Help with K3S upgrades In-Reply-To: <001501d5131e$9f1f4170$dd5dc450$@optilink.us> References: <001501d5131e$9f1f4170$dd5dc450$@optilink.us> Message-ID: <545b7411-542b-9a11-e3ef-49932b2e95f9@embarqmail.com> Hank, You don't need a highly accurate frequency counter. You can get closer with the beat note method. You can use an audio spectrum analyzer (like Spectrogram or SpectrumLab) running on your computer and the K3S rear headphone jack connected to your soundcard Line In. That will give you a visual display. When you turn on SPOT, if the two audio frequencies are far enough apart, you will see two both of them. When both frequencies are quite close, they will appear as one signal. When they are VERY close, you will see the "signal" begin to oscillate in amplitude - when that oscillation slows to zero, that is the beat point you are seeking. In practice it is difficult to get it to exactly zero, but get it as slow as possible - one or two oscillations each minute is practical using that method. If you need Spectrogram (Windows application), go to my website www.w3fpr.com and scroll near the bottom of the opening page to find the links. Those are internal links on my website, and the files have been thoroughly scrubbed for virus - although Norton does not like them because they do not have a large enough user list for that application. 73, Don W3FPR On 5/25/2019 1:23 PM, hbjr at optilink.us wrote: > I have just installed the 1 PPM TXCO in my K3S.

Once done, then tune up from WWV or down from WWV by 10 to 20 Hz and press SPOT again.? The radio should come to 15.000.000.??

With the software approach, any sound card error (which can vary a lot) is corrected so any software using it, is dead on. Bottom line is that unless you're attempting the ARRL FMT, a few hertz won't be noticed by most; aging ears just aren't that good a test and most software isn't that critical either.

However, since last week I have thought about it and I realized that I do not use the VFO B knob very much. Because I have the sub-RX, if I want to search for where the transmitting stations are located, I send the DX frequency to the B VFO/sub-receiver , and tune the pile up with the A VFO. Also because I use diversity rx on the low bands, I am almost always controlling the radio with the A VFO. I also note that the new FTDX-101 does not have a separate "B" VFO knob but this task is handled by switching between "A" and "B" vFO's. My only concern about the "B" VFO is that I believe that the "B" tuning knob on the K4 is a bit smaller than the "B" tuning knob on the K3. That is a step backwards in my opinion and the knob should be made larger.

Thank you for your help!! I tried both Bob and Don?s method after letting the K3S warm up for about 30 minutes tuned into a SW broadcast. After using Bob?s CWT method on 20 Mhz (conditions finally improved enough to get a good S9+ signal), I could tune to any strong broadcast signal and use the CWT and SPOT function and the frequency display would be perfect. Tuning 50 Hz away ? either side ? and pressing SPOT would bring the frequency back to the correct frequency. I tried Don?s method using. I regularly check my soundcard calibration using FLDIGI?s method. I?m using the Timewave PK-232sc+ for a soundcard. It is very stable ? checking it today it required no tweaking. After running the spectrum analyzer, the tuning was dead-on as far as the waterfall showed. Both great ideas!!!! Thanks again for all of the replies. I learned more about my radio today!

I prefer to use CW mode with CWT active .?? Tune the radio to one of the WWV frequencies.? Thn press and release SPOT.? This will match the sidetone to the WWV carrier and adjust the radio to the correct frequency.? If for example, one tunes to 15.000.000 and presses SPOT? the radio may then move to 15.000.002.? If so, adjust the Ref Cal down about 3 or 4 Hz.? And do the procedure again.? It will take 3 or 4 times and adjustments to get the radio "dead nuts on".?? Once done, then tune up from WWV or down from WWV by 10 to 20 Hz and press SPOT again.? The radio should come to 15.000.000.?? Thus no listening, no zero beating, no computer, no external software is needed.? Everything is referenced to the internal Reference.? This also assures the sidetone frequency is accurate at the user selected frequency. 73 Bob, K4TAX On 5/25/2019 1:39 PM, Rick Bates (WA6NHC) wrote: > By ear is very close but if you already have WSJT-X, there is a calibrate mode for the last few Hertz. > > Rick WA6NHC > > Smell Czech correction happen > >> On May 25, 2019, at 11:08 AM, Don Wilhelm wrote: >> >> Hank, >> >> You don't need a highly accurate frequency counter.

I've have the external ref module which actually measures the TCXO frequency and on my K3 the drift is pretty close to over after 60 minutes. I've tracked it all the way to four hours. It is useful to keep an eye on the front panel temp (DISP - FP). The TXCO is located in close order with the front panel and that influences the drift. Mine usually tops out at 37 to 39C.

Here?s an unrelated thing that might be possible as an option on the K4: in CW mode, what if the gain increased gradually as you decreased the bandwidth? It would give a feeling of focusing on a signal. Just a thought.

I've have the external ref module which actually measures the TCXO frequency and on my K3 the drift is pretty close to over after 60 minutes. I've tracked it all the way to four hours. It is useful to keep an eye on the front panel temp (DISP - FP). The TXCO is located in close order with the front panel and that influences the drift. Mine usually tops out at 37 to 39C.

This is exactly the opposite of how I feel about radios -- I'll be 78 in the fall, but I'm still an active guy dragging my gear to portable setups, and my shack is a SO2R contesting setup (single op, two radios). For both reasons, I am VERY happy with the light weight and small footprint of the K3 (as well as it's predecessor, the K2, and relatives, the KX3 and KX2). I don't want big knobs or even a lot of knobs -- when I'm operating, the only knobs I'm using are the gain controls and whatever changes frequency, including RIT or XIT. But what do I know -- I've only been doing it for 63 years. 73, Jim K9YC From tomg3olb at gmail.com Sun May 26 14:35:23 2019 From: tomg3olb at gmail.com (Tom Boucher) Date: Sun, 26 May 2019 19:35:23 +0100 Subject: [Elecraft] Trees eating wire Message-ID: Wayne's problem with a tree eating his wire reminds me of an incident some years ago when I was attempting to get an antenna halyard over a tall oak tree. I used some braided nylon cord with a probable breaking strain of several hundred pounds, which was attached to a drilled golf ball. My catapult put the ball and cord over a branch somewhat lower than intended so I attempted to pull it back. Of course the inevitable happened and the ball wound itself around the branch. No matter how hard I pulled the cord it wouldn't come. So I wound the cord around a piece of wood and with my heels dug into the ground, gave it my full body weight plus some. Finally it released itself and the golf ball shot towards me hitting me in the right foot and breaking several bones. I had literally shot myself in the foot! I'm just thankful it wasn't 2 or 3 feet up otherwise my voice would now be an octave or so higher. Heard the guys sniggering behind the curtain in the hospital A&E department after I told them I had shot myself with a golf ball. XYL not at all impressed at having to drive me to the salt mine for 6 weeks. Lead weights used by anglers could be even more lethal. Needless to say I don't use that method any more and now use a compressed air device with weighted tennis balls which works a treat! 73, Tom G3OLB From rick at tavan.com Sun May 26 14:55:13 2019 From: rick at tavan.com (Rick Tavan) Date: Sun, 26 May 2019 11:55:13 -0700 Subject: [Elecraft] Elecraft K4 and Accessibility In-Reply-To: <0e9401d5128c$da9559c0$8fc00d40$@maine.rr.com> References: <1CC08B58-96C1-4F87-B338-141C2483642E@brannan.name> <2FE75C61-6B01-42DD-9EFA-D5CADA541F6B@elecraft.com> <0e9401d5128c$da9559c0$8fc00d40$@maine.rr.com> Message-ID: Wow. Your preference seems to be in a minority, Harry, although I have to admit that my opinion is subjective and based mainly on what I've read on this reflector which may well be biased by folks like me who *like* the K3. I think Elecraft retained in the K4 many of the design points that made the K3 very successful and enduring, including its light weight and small size which are two major complaints on your list. So it may be a chocolate vs. vanilla situation - some people (like me) value those characteristics while other people (like you) dislike them. Of course, you're right that many prospective buyers are aging and some may come to dislike smaller knobs, I for one still find the knobs and buttons plenty big enough and I'm now 70 years old. I once measured the K3 button size and spacing against my prior favorite rig, the FT-1000MP, and found them practically the same. I never had trouble operating the K3 and its menu structure was logical, rarely needed, and self-documenting. The new K4 screen is plenty large enough for me and comparable to many current, competitive radios'. It can also be blown up to as large as you like through the addition of an in expensive, external, HDMI monitor or a tablet. I've seen it and it was gorgeous. So you're certainly correct that some people like big, heavy radios with "substantial" knobs and they may not buy the K4. Others like radios they can lift without back strain, carry to vacation homes and field sites, operate remotely with minimal external hardware, and expect to survive through upgrades for a decade. Many of them, like me, have been K3 fans for 12 years or so and will be delighted to buy the K4. The market will decide. I think the K4 will be highly successful and I'm rooting for it. We'll see. 73, /Rick N6XI -- Rick Tavan Truckee, CA On Fri, May 24, 2019 at 5:00 PM wrote: > Wayne and interested others, > > Way back when, I bought a loaded K3. I believe the S/N was around 4K?

So it may be a chocolate vs. vanilla situation - some people (like me) value those characteristics while other people (like you) dislike them. Of course, you're right that many prospective buyers are aging and some may come to dislike smaller knobs, I for one still find the knobs and buttons plenty big enough and I'm now 70 years old. I once measured the K3 button size and spacing against my prior favorite rig, the FT-1000MP, and found them practically the same. I never had trouble operating the K3 and its menu structure was logical, rarely needed, and self-documenting. The new K4 screen is plenty large enough for me and comparable to many current, competitive radios'. It can also be blown up to as large as you like through the addition of an in expensive, external, HDMI monitor or a tablet. I've seen it and it was gorgeous. So you're certainly correct that some people like big, heavy radios with "substantial" knobs and they may not buy the K4. Others like radios they can lift without back strain, carry to vacation homes and field sites, operate remotely with minimal external hardware, and expect to survive through upgrades for a decade. Many of them, like me, have been K3 fans for 12 years or so and will be delighted to buy the K4. The market will decide. I think the K4 will be highly successful and I'm rooting for it. We'll see. 73, /Rick N6XI On Fri, May 24, 2019 at 5:00 PM wrote: > Wayne and interested others, > > Way back when, I bought a loaded K3. I believe the S/N was around 4K?

Any Suggestions? Message-ID: <2012631868.3116.1558898159248@wamui-moana.atl.sa.earthlink.net> Good afternoon, I have a ~24" LCD monitor that I want to use for logging, to display my panadapter, etc. Unfortunately, it is very noisy on HF. When It goes to sleep, the noise goes away. This is even more irritating because I now have the K2/computer/logging, etc, all working together. I've searched a bit on-line, but so far, I have not found any real solutions (but a lot of "me too" answers, and one suggestion to ditch the radio and make use of the internet...). There are what look to be ferrite beads on each end of the signal cable from the computer to the monitor, and on the monitor end of the power supply's low-voltage line (I assume it's a switching supply). There are no beads on the supply's power cord. All the radio equipment and the computer are using the same AC circuit. The rig and amp are grounded to the station ground, but the computer and monitor are only grounded through the AC supply. I have four clip-on ferrite beads that I've tried on each end of the monitor's two lines, and they make no difference. Does anyone have any suggestions? Maybe I've missed something dumb. I don't mind getting some big cores if necessary, but I would like to hear of someone's success before spending a lot of money trying to "shotgun" the solution, and I really don't want to get a new monitor - but if anyone has a suggestion of a noise-free one, please let me know.

The base K2 provides power to the critical circuits and MCU in the KPA100 even though the PA is turned off in the menu or not powered via the APP connector. You MUST connect the antenna/dummy load to the KPA100 SO-239 ANT jack - you cannot use the base K2 BNC ANT jack unless you physically remove and disconnect the KPA100.? If you try, the base K2 will think there is no power being produced and will increase drive to maximum - as high as 19 watts uncontrolled power output will result no matter where you set the power control. 73, Don W3FPR On 5/26/2019 2:56 PM, Bill Coleman wrote: > So, if you turn the KPA100 off via the menu, the KPA100 SWR bridge is still used in any case? > > I?ll plan to add 50-100 kOhm resistors across the output, as you suggested.

With my parents' Samsung, the noise is even audible if you're sitting next to it. The only solution I've found, if indeed this is what's giving you trouble, is to turn the backlight brightness up to 100%. Even at 99% the PWM kicks in and makes a hell of a racket.

This is a very common problem. There are (at least) two heads to the snake. The most common, and easiest to fix, is the power supply if it is a wall wart. Wind multiple turns of the power cable through a #31 Fair-Rite core. The other head of the snake is noise from within the monitor itself, which radiates directly from it's own wiring and from the video cable. No fix for what radiates from it's own wiring, but multiple turns of the video cable around a #31 Fair-Rite core will kill that part of the noise. Another very good solution to the power supply component of the problem is to replace the noisy power supply with a quiet one -- namely, a vintage linear supply with a transformer, rectifier, and filter. There's a lot more detailed advice on this on my website. http://k9yc.com/KillingReceiveNoise.pdf http://k9yc.com/KillingRXNoiseVisalia.pdf 73, Jim K9YC From k9qjs at icloud.com Sun May 26 16:05:36 2019 From: k9qjs at icloud.com (JK Hoop Hooper) Date: Sun, 26 May 2019 13:05:36 -0700 Subject: [Elecraft] VERY noisy LCD Monitor.

Mine is 27? by Nixeus - the least expensive 27 inch monitor I could find. Two kinds of problems include broadband noise of about 2 to 3 dB across 20 meters and a specific frequency noise of about 3 kHz wide at about 14.250 MHz. Like yours, the noise goes away when it goes to sleep. Like you, ferrite additions have not worked. I have 2 1/2 inch ferrite cores through which I wrapped the power and signal cables. My solution? Turn off the monitor. It is a second monitor, paired to my iMac 27 inches which has no such noise. A future, more expensive solution will be to get a new, better-hopefully monitor. Not the answer you want to hear, but I feel your pain. 73 Hoop K9QJS On May 26, 2019, at 12:15 PM, Jim KO5V wrote: Good afternoon, I have a ~24" LCD monitor that I want to use for logging, to display my panadapter, etc. Unfortunately, it is very noisy on HF. When It goes to sleep, the noise goes away. This is even more irritating because I now have the K2/computer/logging, etc, all working together. I've searched a bit on-line, but so far, I have not found any real solutions (but a lot of "me too" answers, and one suggestion to ditch the radio and make use of the internet...). There are what look to be ferrite beads on each end of the signal cable from the computer to the monitor, and on the monitor end of the power supply's low-voltage line (I assume it's a switching supply). There are no beads on the supply's power cord. All the radio equipment and the computer are using the same AC circuit. The rig and amp are grounded to the station ground, but the computer and monitor are only grounded through the AC supply. I have four clip-on ferrite beads that I've tried on each end of the monitor's two lines, and they make no difference. Does anyone have any suggestions? Maybe I've missed something dumb. I don't mind getting some big cores if necessary, but I would like to hear of someone's success before spending a lot of money trying to "shotgun" the solution, and I really don't want to get a new monitor - but if anyone has a suggestion of a noise-free one, please let me know.

This is exactly the opposite of how I feel about radios -- I'll be 78 in the fall, but I'm still an active guy dragging my gear to portable setups, and my shack is a SO2R contesting setup (single op, two radios). For both reasons, I am VERY happy with the light weight and small footprint of the K3 (as well as it's predecessor, the K2, and relatives, the KX3 and KX2). I don't want big knobs or even a lot of knobs -- when I'm operating, the only knobs I'm using are the gain controls and whatever changes frequency, including RIT or XIT.

From a.durbin at msn.com Mon May 27 19:05:36 2019 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 27 May 2019 23:05:36 +0000 Subject: [Elecraft] KAT500 VSWR Threshold for key interrupt Message-ID: The KAT500 utility provides the means to set a VSWR threshold for Key Interrupt either by individual band, or the same value for all bands. Selecting ALL, entering 1.50 in the Amplifier Key Interrupt box, selecting Apply, results in 1.50 being set for all bands as expected. After the operation Apply is dim. Leaving the Config menu and returning to it still shows 1.50 selected for all bands. If All is reselected, 1.60 entered, and Apply selected then Apply does no go dim but the individual bands, and ALL, each show 1.60. Then select OK and Operate. Then return to Configuration, edit Configuration, VSWR Thresholds. With ALL selected Amplifier Key Interrupt is blank. Inspecting the value for each band shows 160 = 1.59 and all other bands 1.50. The entered value of 1.60 was not applied. This anomaly seems repeatable in that 1.50 can be entered, 1.55 can be entered, 1.80 can be entered, but 1.60 and 1.56 cannot be. The sign that that data entry has failed is that Apply does not go dim. Is this a known problem with KAT500 utility 1.16.7.25?

But I did get a chance to put my K4 through its paces in WPX for the first time, and had a blast. Even though the "hard" controls of the K4 are very similar to those on the K3 (or K3S), the kinesthetic operating experience is quite different due to its display-centric design. The average "reach" as you manipulate panadapter settings vs. other settings on the radio is cut roughly in half. There's a modest learning curve associated with the three new multifunction controls, given that they're remapped from their counterparts on the K3. But you quickly realize the advantage of persistent parameter labeling. All semantically related operations are efficient; just push the knob briefly to toggle between them. For example, in CW mode the "XMTR" multifunction knob's default assignments are WPM and SPEED, each showing their current settings. The secondary assignments -- DLY (VOX delay) and PTCH (CW sidetone/offset pitch) -- are also displayed, and can be selected as needed. I made things more challenging by using only 10 watts during the contest and sticking with hunt 'n' pounce. (Those who've known me for a long time won't be surprised by this. I love the smell of lightly toasted electrons in the early afternoon.) This forced me to make more extensive use of the radio's panadapter, VFO, and spotting controls: carefully selecting which stations to call, using VFO B as a leapfrog/holding register for the next-most-likely contact, optimally setting up the span and main/sub filter bandwidths, etc. Compared to parking on a frequency and calling CQ, my preferred modus operandi is akin to the visceral experience of driving a stick. Despite my obvious bias as a developer of the radio, I have to say that I really love the radio's display. It's very bright and has an extra-wide viewing angle. It drew in unsuspecting passersby, such as my college-age daughter, who seemed mesmerized by it despite having no clue what I was up to. If we ported Instagram to the internal computer she'd be on the waiting list for sure. With a heavy discount, mind you. I could have made great use of the mini-pan tuning aid and dual-pan configuration, but both are in software dry dock right now as they undergo last minute tweaks. I'll be running them through crunch conditions soon and will report the results here. Field testers, of course, will be weighing in with a lot more data in coming months.

Since there is a splitter there is a 3dB or so loss in the signal. It's worth trying out. The latest releases also come with the EiBi shortwave databases and will show the station info on the spectrum. It's amazing how many shortwave stations are still out there and when you think propagation is bad, you will still finds lots to listen to. Brings back memories as a young kid with my two transistor SW converters.. This set up if you can stand the wiring, will work with the KPA100, KPA500 and the KAT500. 73 Tom va2fsq.com -----Original Message----- From: Don Wilhelm Sent: May 27, 2019 8:15 PM To: Adam Goler ; Tom Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] KX2 waterfall Adam, As I understand it, the KX2 is the receiver for your normal operating.

No reading on internal counter. I popped it on my external Racal counter and still dead. After tracing the problem out I found that the voltage on input to the varactors was pegged at 7.07V which was too high for the oscillation to carry on.

All good. However the input to U6A pin 3 from the LTC1451 DAC is stuck at 4.095V (top end of DAC range by the looks of it) which is forced up by the opamp.

Message-ID: Gm Group I connected a newly acquitted ?twin? Amp and Tuner in a separate enclosure setup this weekend. While bench testing with a dummy load I noticed that I would get high a current message if the power setting was turned over midway, and the amp was trying to produce more than 100 watts! I disconnected the Amp and Tuner, continued to test the bare K2. On 40 meters my power setting wasn?t tracking the actual output. The actual power out was a lot higher than the radio?s setting. I downloaded the calibration instructions and continued testing. When I Set the power to 2 watts and attempt to peak the 40 meter coils, The power goes up to over 10 watts? I pulled the lids and looked at the connections around the 40 meter coils, also I did a reflow on the connections in that area. I?m trying to understand the cal instructions? If you set the control at 2 watts and peak the two coils, and the power is higher, how will it track accurately? I?m trying to decide if I have a problem With my Radio, or am I just not understanding the calibration instructions?? I went to Don?s website and downloaded his condensed instructions, but I was too tired to give them a try!!

Since you indicate that the problem exists with only the base K2, that is the place to start troubleshooting. Do not connect the KPA100 - it must be physically removed. Set the power to about 2 watts, but monitor the actual power with an external wattmeter and drive a dummy load. Then do a TUNE while monitoring the VRFDET signal. It is easiest to probe at Control Board P4 pin 10. Limit the time for a TUNE to 15 to 20 seconds if the actual power is going to maximum (it may be as high as 19 watts). If the DC voltage on VRFDET is near zero, the RF Detector is not working for some reason - replace RF Board D19 and try again. If still no voltage on VRFDET, reflow the soldering on RF board R66, R67, R68, R69 and C77. Should you find a DC voltage that is above 3.5 volts, D19 is working fine, but the MCU is not responding. The most likely problem is that the MCU (Control Board U6) has a damaged input at pin 2. In that case, it has to be replaced. Here things may get a little complicated depending on the level of your current MCU. If it is 2.04P or 2.04r, you can order FW-K2MCU and simply replace U6. If it is less than that, you must order FW-K2MCIO and replace both CB U6 and RF Board U1. So hope the problem is D19, that is inexpensive, but the firmware is expensive. 73, Don W3FPR On 5/28/2019 7:39 AM, Johnny Matlock wrote: > Gm Group > I connected a newly acquitted ?twin?

Anyone know the status of Greene County Fairgrounds buildings? I?ve seen no reports about the Fairgrounds (which is a good thing). There are news reports of trees down in Greene County (which includes Xenia and Beavercreek) and a barn damaged probably due to a tornado. There are also electrical outages. The fact that the Fairgrounds was not mentioned in local news coverage probably means that the Fairgrounds did not take a direct hit.

I used the AX1 as a test in WPX CW last weekend for only an hour on a picnic table. No problem ...in that time I got 13 QSOs from FN45 including FL. (10 Watts KX2, 13' counterpoise). -- After NEC simulations (0.005, 13 average ground) , we find how the gain is maximized in the direction of the counterpoise. On 20 meters, if the wire is horizontal at 4 feet height, the take-off angle is about 56 degrees. But if the wire goes down from 4 feet to the ground (15 degrees slope), the F/B is less but the take off angle is lower at 35 degrees (Image at https://i.imgur.com/XKPjM8T.jpg ) 73, Pierre VE2PID ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From kevin at ve3syb.ca Tue May 28 13:45:37 2019 From: kevin at ve3syb.ca (Kevin Cozens) Date: Tue, 28 May 2019 13:45:37 -0400 Subject: [Elecraft] OT: Dayton area In-Reply-To: References: Message-ID: <6313def0-c84a-2fe0-fb32-b109a9640dc9@ve3syb.ca> On 2019-05-28 12:35 p.m., Ken G Kopp wrote: > The Weather Channel spending lots of time on the Dayton area today.

The computer COM port (or USB to serial adapter) is normally considered as the output device. First assure yourself (or contact support for those devices to be certain there are no RS-232 DRIVERS (receivers are OK) in their RS-232 ports, and if there are drivers, can they be disabled. There must be only one driver on each line of the RS-232 connection or the circuits will not work because an active driver's voltage level will interfere with the inactive drivers. See information on RS-232 for more complete information and voltage levels of active and inactive drivers. You will need two RS-232 DE9 Y adapters (unless you can find one with one female 3 male connectors. The female connects to the computer and one each of the male connectors go to the K3, your amp, and the antenna switch. 73, Don W3FPR On 5/28/2019 12:58 PM, PY2KP wrote: > Hi Guys > > I bought a K3 and only have an RS232 output, I need to control a linear OM and antenna switch. > How could I control the two devices ?

I heard from Madelyn at Sales this morning. The answer is that, in such a circumstance, the deposit could be refunded; but the place in line could not be transferred. If the original deposit-maker doesn't take delivery, their place is taken by whoever is next. Reporting this is not a complaint on my part. The company's policy would be justifiable either way.

The northern edge of the impact area picked up Celina (40 mi NNW of Dayton) and extended SE to SE Pickaway County (but staying south of Circleville). Like all tornado events in that part of the country, the major damage was spotty as the funnel clouds skipped along ... and more focused on the western end of the storm track in this case. 73, ...

The same K3 "upgradeable approach" applies to K4.? If you are not into contesting then K4 SDR may be all you wish (especially if you already have a K3 for contesting). You do have to pay for the upgradeable approach even if you are not interested in upgrading. This is the advantage of Elecraft IMHO.? I purchased my first k3 in 2008, and it is as good in 2019 as my K3s.? An upgradeable radio also helps with radio repair cost, in addition to NOT purchasing a new model radio just to obtain improved performance. Before I ended up with K3/P3 so2r in 2015, I went through a new board to improve K3 audio, the replacement of the pins affecting the KPA3 module, and new synthesizers (plus a few minor mods). My K3 eventually replaced ft1000mp, Omni VI, and (finally) Orion. I'm satisfied using K3 so2r more so than at any point in the past. Based on my past experience I suspect K4 has a bright future! 73, Will, wj9b PS: This is not the same as saying that I do not like other radios. I still have Orion and a broken Omni VI that I hope to repair.

Your preference seems to be in a minority, Harry, although I have to admit that my opinion is subjective and based mainly on what I've read on this reflector which may well be biased by folks like me who *like* the K3. I think Elecraft retained in the K4 many of the design points that made the K3 very successful and enduring, including its light weight and small size which are two major complaints on your list. So it may be a chocolate vs. vanilla situation - some people (like me) value those characteristics while other people (like you) dislike them. Of course, you're right that many prospective buyers are aging and some may come to dislike smaller knobs, I for one still find the knobs and buttons plenty big enough and I'm now 70 years old. I once measured the K3 button size and spacing against my prior favorite rig, the FT-1000MP, and found them practically the same. I never had trouble operating the K3 and its menu structure was logical, rarely needed, and self-documenting. The new K4 screen is plenty large enough for me and comparable to many current, competitive radios'. It can also be blown up to as large as you like through the addition of an in expensive, external, HDMI monitor or a tablet. I've seen it and it was gorgeous. So you're certainly correct that some people like big, heavy radios with "substantial" knobs and they may not buy the K4. Others like radios they can lift without back strain, carry to vacation homes and field sites, operate remotely with minimal external hardware, and expect to survive through upgrades for a decade. Many of them, like me, have been K3 fans for 12 years or so and will be delighted to buy the K4. The market will decide. I think the K4 will be highly successful and I'm rooting for it. We'll see. 73, /Rick N6XI -- Rick Tavan Truckee, CA On Fri, May 24, 2019 at 5:00 PM wrote: > Wayne and interested others, > > Way back when, I bought a loaded K3. I believe the S/N was around 4K?

(I have pre-ordered.) The VE6WZ station is a 100% remote station. My remote QTH is a purpose built station with a low-band focus. I have some questions, and perhaps comments about what the remote functionality of the K4 will look like. Currently at my remote is the K3 twin setup (rcc-1258 remoterig boxes) and the Flex 6600. I can switch between either radio. My radio of choice for weak signal CW remains the K3, because of the superior RX. However, the Flex is my preferred radio when traveling away from the home QTH because of the interface to the laptop. Using the Flex SmartSDR software on the laptop and the Flex control knob (like the Kpod) it is exactly the same as sitting at home. The K3 on the other hand requires the remoterig rcc-micro dongle and clumsy third party radio interface software, and will not allow dual channel diversity rx. So...my questions/comments: I will never actually see the K4. For all it?s beauty, it will be sitting at my remote shack all by itself never to be touched. Control will be entirely dependant on the ?yet to be seen? PC control software. This software is crucial to my operating. 1.) Will the K4 return the CW sidetone back from the remote to the control station PC? Believe it or not, Flex has not corrected this deficiency in their radios even though users have been complaining about it for 5 years! This is important to many remote operators who, like myself CW key the radio ***at the remote PC*** which is sitting beside the radio at the remote. (This eliminates any chance of corrupted CW from packet loss...which DOES happen) Even if the radio is keyed at the control PC with N1MM, we still need the sidetone returned. All this is done perfectly with the remoterig K3 twin set-up, so I?m assuming this will be done, but after the Flex experience I had to ask. 2.)Apart from the possibility of a K4/0 (front-panel), is there a possibility of a K4 with a detachable front panel, or a K4/0 and a ?K4 radio-only? (no front panel) option? This is not a deal breaker for me since I use PC only control exclusively with the Flex and it is great. Using the Flex control knob I have complete radio control and all CW is sent via the keyboard. I did own the Maestro, but never used it so sold it after a few months. 3.) I hope some functionality will be available to adjust the internet bandwidth for those with limited connection speed. 4.) will the K-pod be available for use with the PC at the control station? 5.) the Flex can integrate DX spots from my logging program directly onto the waterfall on the PC and they are available for ?point and shoot? radio control. Is such a feature possible with the K4 architecture? 6.) As explained above, the remote software functionality is crucial for my operating, and committing to a radio purchase prior to viewing is not possible. Is there an eta for when the remote control software will be released for preview, or at least is it planned to be available before radios begin to ship? I was at Dayton and did speak to both Eric and Wayne, but I forgot some of these questions...and the crowds were thick! de Steve Ve6wz From Babcocks iPhone From donwilh at embarqmail.com Tue May 28 18:12:17 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 28 May 2019 18:12:17 -0400 Subject: [Elecraft] K2 Over Current High Power 40 Meters.

I presume he means the Flex M radios and the newly released Mk 2 Anan which do have knobs while the predecessors do not. I thought about my recent usage of my K3. After pressing the power button, I set the output power to drive my alpha amp, and while operating adjusted the audio level control and infrequently the audio passband filter, turned on XIT 20 Hz low when pouncing or used RIT when running, rarely touched high and low cut, and used the VFO. Using N1MM I am able to tune the radio, change bands, adjust the keyer speed, clear the RIT and toggle it on and off, and even spot tune a CW signal. I like the organization of the knobs and buttons that it does have. Those that are dual function do not confuse me at all. I do not find the buttons too small and they are definitely not too cluttered. I operate portable a lot in the summer. The compact size and light weight are a plus. I am older than Rick T. You commented about the 6700?s place on the Sherwood tables. Yes, it is in second place for 2 KHz offset dynamic range, but not for 20 KHz offset. Oh, did you read footnote ?y? ?

I've seen no mention of how they are to be selected though. In my imagination, I see pressing the RX ANT button putting a list of up to 5 antennas on the screen. This is pretty close, Bob. There are actually four antenna controls on the K4: ANT (tap) Selects the transmit antenna (if a KAT4 is installed: ANT 1/2/3) REM ANT (hold) Might be used to control a remote antenna switch, rotator, etc. (future) RX ANT (tap) Selects the main RX antenna (default: TX ANT) SUB ANT (hold) Selects the sub RX antenna (default: TX ANT) When you tap RX ANT or hold SUB ANT, you'll get a pick list of all available antennas for that receiver. In the case of the K4D or K4HD, you can make independent selections for these, because they both include the diversity option module (with a second ADC, second set of band-pass filters, and separate set of of RX antenna relays). The default antenna for both receivers is the selected transmit antenna. This means the signal goes through the KAT4 ATU and its antenna switch (ANT 1, 2, 3). The other possible receive antenna choices are: RX ANT 1 RX ANT 2 (which doubles as XVTR IN) Either of the two KAT4 *non-transmit* antennas ANT 4 is reserved for use with the future VHF/UHF module. The connector could be UHF or N. 73, Wayne N6KR From Hamshack at N4ST.com Wed May 29 00:03:45 2019 From: Hamshack at N4ST.com (Jim - N4ST) Date: Wed, 29 May 2019 00:03:45 -0400 Subject: [Elecraft] K3S: CW and Digital Interface In-Reply-To: <9286a2db-dbfb-6247-b08d-3436dc5ca9de@rthorne.net> References: <9286a2db-dbfb-6247-b08d-3436dc5ca9de@rthorne.net> Message-ID: <011e01d515d3$873025e0$959071a0$@N4ST.com> If you have the Winkeyer, just connect that to the key input of the K3S.

The front panel talks to the guts of the radio via Ethernet so any local or remote K4 can control another local or remote K4, including the entire front panel display and controls. - I saw the tablet app which was beautiful but I didn't delve into what it could and couldn't do. They talked about a similar PC app but I didn't see it. But I am confident that I'll be able to configure my mountain remote station so that I can access it either from my valley QTH or from a hotel room without any cabling differences. - I vaguely recall hearing that K*Pod will be supported with either a tablet or PC app. That will be awesome when I travel and want to do some casual ham radio. - If you use N1MM Logger+, you can display clickable call signs on its spectrum display. I think there will be some N1MM programming needed to support direct I/Q input from the K4 but I'm confident the MM development team will be right on top of that. If there is a delay, I know I can use an external Airspy HF+ SDR in the K4 RX ANT loop the way I do with my K3's. - They said a K4/0 was in the offing but not real soon. - I am confident that K4 remote operation will be better than the K3-RRC--RRC-K3 configuration I use today. 73, /Rick N6XI -- Rick Tavan Truckee, CA On Tue, May 28, 2019 at 2:52 PM VE6WZ Steve wrote: > I eagerly await the K4.

Well, we both agreed that since the K3S has world class receiver specs, that would not be a bad thing. I started comparing the information about the K4HD with the K3S manual and found: K3S K4HD Feature 8.215MHz ~8MHz First IF 15KHz ? Second IF (if used in the K4) 24 16 ADC width ~30KHz? 122MHz ADC sample rate (WAG for the K3S) 5 2+1 Crystal filters (one empty slot is from a post on this list.) Note: In the K4 FAQ there are forward references to a K4HD section, but I couldn't find it on the web site. Analysis and wild speculation Both DSPs and ADC technology have had at least 10 years to improve between the K3S and the K4. WHile I don't track ADC tech, DSPs are computers and we all know what has happened in computers. The basic processors are somewhat faster, and there are many more cores on a chip. The K4 certain to have taken advantage of these improvements. The K3S uses a 32 bit floating point DSP, and I don't see any reason to change that specification for any of the K4 models. Not changing means that much of the K3 DSP code should easily port to the new DSP. I don't understand how the basic K4 can get good dynamic range with a 16 bit DAC. The K3's 24 bit DAC seems a better choice, although getting high speed and wide bit width at the same time is hard and expensive. In the wild speculation department, there seem to be several approaches for the K4HD. (1) Run a K3 like superhet with an ~8MHz IF and digitize that into the DSP. (2) Duplicate the K3's 2nd IF and use the 16 bit ADC at 15Khz. (3) Use a wider ADC at either 8MHz or at 15KHz. Note that one of the features of the K4 is ease of upgrade to new ADCs. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz |"Web security is like medicine - trying to do good for 408-356-8506 |an evolved body of kludges" - Mark Miller www.pwpconsult.com | From Jeff at scaparra.com Wed May 29 03:55:18 2019 From: Jeff at scaparra.com (Jeff Scaparra) Date: Wed, 29 May 2019 02:55:18 -0500 Subject: [Elecraft] K4 DSP bit width In-Reply-To: References: Message-ID: Comparing a 24 bit ADC at a 32 KHz sample rate to a 16 Bit ADC at 122 Msps and saying it is less bits and therefore will have worse performance isn't a great comparison.

Many thanks. After this, the PLL calibration routine completes successfully. The EEPROM appears to be ok here. So at a high level the issue appears to be: 1. The J310 or circuit was at fault. Either the J310 device spread is suspect or the circuit is device spread sensitive. Having built a few VXOs over the years some problems are almost inevitable here so it's expected really. 2. The default EEPROM contents without PLL calibration have no calibration data so it's not possible to tune the oscillator down into a running state, not that it'd help potentially based on point 3. 2. The default DAC value of full scale pegs the varactors at full swing resulting in the oscillator not starting. 3. The PLL calibration routine will not run if the oscillator is not running which is fair enough. Diagnostic steps to positively identify the issue: 1. Reset K2 (456+power up) to clear cal data. This will wedge the DAC at full scale. 2. Hook scope/counter to TP3 (internal counter is fine). If there is a signal here at around 12MHz, then the oscillator works. No further diagnostics required. 3. Lift one end of R19 to disconnect the DAC from the PLL oscillator. 4. Hook bench supply to RP2 pin 2 or 4. Set on 0V. 9v battery with 1k pot across it and DMM on wiper terminal will do if you don't have a bench supply. 5. Sweep bench supply across 0-8V and ensure that there is a signal at TP3 across the entire range. 6. If there isn't replace Q19 (J310) and retry until there is oscillation across the entire range. 7. Reinsert and solder lifted end of R19. 8. Complete PLL calibration. As a test, I also tried an NOS On Semiconductor J310 (which arrived the same time as Elecraft's replacement!) and that worked consistently across the board. I have however substituted the Elecraft supplied replacement which matches the On Semi one now as well. Thanks to Don for landing on this issue straight away. Next steps in progress now.

No reading on internal counter. I popped it on my external Racal counter and still dead. After tracing the problem out I found that the voltage on input to the varactors was pegged at 7.07V which was too high for the oscillation to carry on. I lifted one end of R19 on the output of U6A and the thing oscillates fine isolating this to a control voltage problem. > > >>> > > >>> Next I checked voltages on the thermistor board and input of the opamp. All good. However the input to U6A pin 3 from the LTC1451 DAC is stuck at 4.095V (top end of DAC range by the looks of it) which is forced up by the opamp. Popped U5 DIN on the scope and spun the VFO and it sends the same data word to the DAC every time regardless of VFO position.

Perhaps it?s the way I phrased it. So, let me ask it a different way: 1. Noise Blanking: On the website, under K4 FAQ - Performance Differences, it says "In a direct-sampling radio like the K4, the DSP can ?see? a wider bandwidth in its signal chain, allowing it to provide higher-performance noise reduction, noise blanking?? Can you quantify the improvement of the K4 over the K3S regarding noise reduction and noise blanking? 2. Sensitivity: Rob Sherwood?s transceiver test data shows the following sensitivity for the K3S (in microvolts): 0.27 0.20b 0.0810 b Built-in preamp actuated 10 10 meter data, preamp ON How does the K4 compare with the K3S on this measure of sensitivity?

I've seen no mention of how they are to be selected though. In my imagination, I see pressing the RX ANT button putting a list of up to 5 antennas on the screen. This is pretty close, Bob. There are actually four antenna controls on the K4: ANT (tap) Selects the transmit antenna (if a KAT4 is installed: ANT 1/2/3) REM ANT (hold) Might be used to control a remote antenna switch, rotator, etc. (future) RX ANT (tap) Selects the main RX antenna (default: TX ANT) SUB ANT (hold) Selects the sub RX antenna (default: TX ANT) When you tap RX ANT or hold SUB ANT, you'll get a pick list of all available antennas for that receiver. In the case of the K4D or K4HD, you can make independent selections for these, because they both include the diversity option module (with a second ADC, second set of band-pass filters, and separate set of of RX antenna relays). The default antenna for both receivers is the selected transmit antenna. This means the signal goes through the KAT4 ATU and its antenna switch (ANT 1, 2, 3). The other possible receive antenna choices are: RX ANT 1 RX ANT 2 (which doubles as XVTR IN) Either of the two KAT4 *non-transmit* antennas ANT 4 is reserved for use with the future VHF/UHF module. The connector could be UHF or N. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From w2up at comcast.net Wed May 29 09:27:39 2019 From: w2up at comcast.net (Barry) Date: Wed, 29 May 2019 06:27:39 -0700 (MST) Subject: [Elecraft] Hara Arena Hit by Tornado In-Reply-To: <4A37BE7A-E4EF-4F16-8671-D47AE57357A1@qth.com> References: <7085bb6a-5304-82aa-45bc-9267489545b7@kj0f.com> <0ebd01d51576$e8dd7750$ba9865f0$@arrl.net> <4A37BE7A-E4EF-4F16-8671-D47AE57357A1@qth.com> Message-ID: <1559136459107-0.post@n2.nabble.com> Carl-N8VZ wrote > According to what I was told, the Greene County Fair Board has agreed to > put in air conditioning in the three main buildings if the the Hamvention > folks will sign a long-term contract.

Thru-hole J310s have been discontinued. Last August, Elecraft ordered a new supply (from a new source) which proved to be inadequate for the K2 PLL Reference Oscillator circuit. A source of New Old Stock for J310s was sought and finally found. Those parts were received in January 2019 and the stock that was deficient was scrapped. 2. So the K2s which were affected were shipped between mid-August 2018 and January 2019. Not all J310s shipped during that period were sub-par, some worked fine while others did not. 3. So this problem reared its ugly head on some of the K2s shipped during that period while others worked fine. The problem would show up during the PLL Reference Range Test during early testing of the K2. Many have been corrected so far, actually I hope all those which failed have now been corrected - time will tell. With the current stock of J310s at Elecraft, this problem has been solved. Warranty support for those K2s exhibiting the problem will be addressed as the symptoms are revealed. The circuit is not to blame. The circuit has been unchanged since the Field Test K3s and it has worked successfully until this J310 situation came up. There are no new thru-hole J310s being manufactured from the original manufacturers - SMD J310s have no problems. 73, Don W3FPR On 5/29/2019 4:56 AM, Chris Smith wrote: > Hi, > > I have replaced the J310 and the oscillator now runs over the full voltage range of the DAC.

Either the J310 device spread is suspect or the circuit is device spread sensitive. Having built a few VXOs over the years some problems are almost inevitable here so it's expected really.

I've seen no mention of how they are to be selected though. In my imagination, I see pressing the RX ANT button putting a list of up to 5 antennas on the screen. This is pretty close, Bob. There are actually four antenna controls on the K4: ANT (tap) Selects the transmit antenna (if a KAT4 is installed: ANT 1/2/3) REM ANT (hold) Might be used to control a remote antenna switch, rotator, etc. (future) RX ANT (tap) Selects the main RX antenna (default: TX ANT) SUB ANT (hold) Selects the sub RX antenna (default: TX ANT) When you tap RX ANT or hold SUB ANT, you'll get a pick list of all available antennas for that receiver. In the case of the K4D or K4HD, you can make independent selections for these, because they both include the diversity option module (with a second ADC, second set of band-pass filters, and separate set of of RX antenna relays). The default antenna for both receivers is the selected transmit antenna. This means the signal goes through the KAT4 ATU and its antenna switch (ANT 1, 2, 3). The other possible receive antenna choices are: RX ANT 1 RX ANT 2 (which doubles as XVTR IN) Either of the two KAT4 *non-transmit* antennas ANT 4 is reserved for use with the future VHF/UHF module. The connector could be UHF or N. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html From n6kr at elecraft.com Wed May 29 10:22:53 2019 From: n6kr at elecraft.com (Wayne Burdick) Date: Wed, 29 May 2019 07:22:53 -0700 Subject: [Elecraft] K4 RX antenna ports In-Reply-To: References: <21604.1559074084676464540@groups.io> <5BC15BC8-79DD-4E4E-9EFD-38665A350CE7@elecraft.com> Message-ID: > Jim Miller (ab3cv) wrote: > > If/when implemented how would the REM ANT control communicate with the controlled device?

There should be no RF input to the KPA500 when on 2M, and when on HF+6M there should be no RF input to your 2M amplifier. So, are you OK with keying both amplifiers all the time no matter which band is selected? If so, then just connect the KEYOUT line to your 2M amp and make no changes to the connection to the KAT500/KPA500. OTOH, if you do not wish to key both amplifiers all the time, you will need to use the Keyline interrupter and cable the KeyOut from the K3 to some sort of switching arrangement (could be manual or automated through a band decoding device) so the K3 KEYOUT line is routed to the 2M amp when 2M is selected and to the KAT500/KPA500 when 2M is NOT selected. The decision depends on your desires. Do NOT use both the AUX cable without the keyline interrupter and the RCA keyline connections to the KAT500/KPA500 - strange things can occur. 73, Don W3FPR On 5/29/2019 9:10 AM, Mike Sanders wrote: > I have a K3 with built in 2M transverter.

The KAT4 is an option, as is correctly stated throughout the K4 web page and order forms. This was also made clear at Dayton for those placing an order. But you're right, we need to clarify this in the sales brochure. (I was in a huge hurry trying to get that copy ready in time for the hamvention.) > Also, is it true that the K4 has just one receiver? Not true. Even a basic K4 can do dual receive, with identical performance on both receivers, on any two frequencies in the full tuning range (100 kHz - 54 MHz). The two receivers have independent VFO and gain controls, and separate setting of all RX functions including modes, filters, NB, NR, etc. They can even do text decode in two different modes simultaneously, with two separate text-decode windows. The basic K4 can also be set up to display two panadapters (and two high-resolution mini-pans). The K4D and K4HD add a second ADC and a second full set of band-pass filters to allow for diversity operation. A basic K4 can be upgraded to this configuration at any time, in the field, with no soldering. 73, Wayne N6KR From donwilh at embarqmail.com Wed May 29 10:36:25 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Wed, 29 May 2019 10:36:25 -0400 Subject: [Elecraft] K2 PLL reference oscillator problems (DAC side!)

Bob, I have a Hara story. Several years ago, while setting up to demonstrating the KX2, I was cursing the building's steel construction. The only signals I could hear on HF were the on-site demo station, RTTY from an Elecraft XG4 sig gen at the QRP Works booth, and a bunch of *&*#^%@ from nearby computers. I was determined to install an antenna outside. First, I traded "future considerations" for 100 feet of coax at one of the antenna vendors. Next -- and this took about half an hour -- I convinced a guy on the Hara ground crew to drive the elevated lift truck over to our booth. I handed him the coax, which he strung through the rafters some 20' off the ground, with the final catenary terminating near the exterior wall. At this location we had discovered a hole just large enough to accommodate a PL259. The problem was getting the coax up to the hole, which was at about the 15 foot level, directly above a nice display of screwdriver antennas. Again the groundsman stepped up, bringing us a ladder. Unfortunately we still couldn't reach the hole, so we taped the coax connector to the end of a push-up mast in such a way that, when it was poked through the hole, the tape would break, dropping the coax to the ground on the other side. At least that was the plan. It took several tries. Once we had breached the wall, we redeployed the ladder outside and attached wires to form an OCF dipole. Lord knows what the resonant frequency was. We didn't care. We'd be using the internal auto-tuner in the radio to tune it up. One end of the dipole sailed cleanly into a tree after several tries by different Elecraft staff members. One of us was almost but not actually injured by the attached weight. The other end flopped uselessly on the metal roof, so we sent Bob Wolbert (K6XX, a veteran of many precarious antenna installations) up to fix it. The kind folks at Hara allowed our coax and antenna to remain in place for the next two shows. No doubt it is still there, part of the ancient infrastructure kept that wing of the building from collapsing in the tornado. 73, Wayne N6KR From Tbry441 at myfairpoint.net Wed May 29 11:19:25 2019 From: Tbry441 at myfairpoint.net (Thaire Bryant) Date: Wed, 29 May 2019 11:19:25 -0400 Subject: [Elecraft] AX-1 DX Message-ID: <9BD27C37-3D1D-457A-8307-3A50EF21070F@myfairpoint.net> In January, when I received my AX-1 I set it up on the deck (on a tripod and with the one radial) and promptly worked LZ and YO on 20 M from New Hampshire.

But there have not been 500 of them over the last 22-days. Our most destructive earthquake since the 1964 "Big One" was last Nov. 30 at 7.1. We were about 85 miles south of the epicenter so suffered no loss. At least there is no regular season each year for earthquakes. I grew up in central MI where each spring brought tornado season. We were at the extreme edge of the normal range for them so didn't worry (much). Living in tornado country one develops a second-sense of the wx conditions that spawn them. We lived in houses with basements so had shelter. Many homes these days are built on concrete slabs so one has to shelter in the bathroom. Glad those days are long gone. We just have four volcanos that have erupted since I moved here within 50-100 miles (and an occasional earthquake). 73, Ed - KL7UW From: Wayne Burdick To: Phil Hystad Cc: "elecraft at mailman.qth.net" Subject: Re: [Elecraft] Hara Arena Hit by Tornado So... you?re not worried about the Cascadia subduction zone?

Basically, there are limits to achievable dynamic range with an A to D converter (direct sampling). The superheat module improves dynamic range by protecting the demodulation channel with narrow band crystal filters. In particular, blocking dynamic range (BDR) improves by 20 to 30 dB. This may be important for stations that have a nearby high-powered broadcaster, or in a multi transmitter environment. The HDR module can be turned on when needed, either manually or automatically. When it?s turned off, the K4 will use its normal direct sampling for the demodulation channels. In all cases, direct sampling is used for the panadapters. 73, Wayne N6KR ---- elecraft.com > On May 28, 2019, at 7:55 PM, Charlie T wrote: > > What exactly does the Superhet Module added to a K4D actually do? > It's obviously a desirable improvement add-on, but that's about all I know. > > I must have missed the explanation if it was provided. > > 73, Charlie k3ICH > > > > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html From W2xj at w2xj.net Wed May 29 12:37:07 2019 From: W2xj at w2xj.net (W2xj) Date: Wed, 29 May 2019 12:37:07 -0400 Subject: [Elecraft] K4 DSP bit width In-Reply-To: References: Message-ID: <927430CD-72B2-453C-A9B0-7253236842E4@w2xj.net> The K4 is a direct sampling radio. It has no IF. It samples directly to IQ baseband and performs all filtering and processing in the digital domain. That requires a very high speed ADC. In this case it is just above the Nyquist limit for 6 meters. Getting a 16 bit converter that fast approaches the limit of available technology. These converters are pipeline architecture and have better than 90 db dynamic range. Looking at S units, there is 88 db from S1 to 40 over S9 before any attenuation or AGC is applied prior to the ADC. The problem comes when there are signals exceeding that dynamic range like working someone who might be S1 or S2 while someone else is transmitting nearby as a direct conversion radio has no front end selectivity. As Eric already explained, this is the reason for the K4HD option. This appears to essentially be a K3S superhet single conversion front end that feeds an approximate 8 MHz IF into the ADC. It would then provide a very narrow band reception option for the K4. Looking at K3s architecture, the ADC is a PCM1804 which is a delta sigma converter which is basically a one bit ADC clocked at 768 times the sample rate or somewhere between approximately 24 and 36 MHz depending on what sample rate Elecraft selected. In the mode used in the K3S it can sample up to 48 KHz although there are other modes permitting up to 192 KHz. The one bit sample is decimated to 24 bits. This ADC is a fairly typical high end stereo audio converter. The two approaches are very different and each fulfills a different need. Fortuneately, the K4 can provide both with the right options installed.

(1) Run a K3 like superhet with an ~8MHz IF and digitize that into the DSP. (2) Duplicate the K3's 2nd IF and use the 16 bit ADC at 15Khz. (3) Use a wider ADC at either 8MHz or at 15KHz.

There should be no RF input to the KPA500 when on 2M, and when on HF+6M there should be no RF input to your 2M amplifier. So, are you OK with keying both amplifiers all the time no matter which band is selected? If so, then just connect the KEYOUT line to your 2M amp and make no changes to the connection to the KAT500/KPA500. OTOH, if you do not wish to key both amplifiers all the time, you will need to use the Keyline interrupter and cable the KeyOut from the K3 to some sort of switching arrangement (could be manual or automated through a band decoding device) so the K3 KEYOUT line is routed to the 2M amp when 2M is selected and to the KAT500/KPA500 when 2M is NOT selected. The decision depends on your desires. Do NOT use both the AUX cable without the keyline interrupter and the RCA keyline connections to the KAT500/KPA500 - strange things can occur. 73, Don W3FPR On 5/29/2019 9:10 AM, Mike Sanders wrote: > I have a K3 with built in 2M transverter.

If I would have known Elecraft was going to share the link, I would have waited to upload the 4K version of the K4. :) If you have 4K capabilities, you can now see Eric Swartz immortalized in 4K 60 frames per second on your high computer or 4K capable big screen TV. Is this overkill for an interview / Q&A video, yes... but hey, it's 2019 and the long awaited K4 has been announced, so it makes sense to have a 4K UHD video of the K4 (Palindrome ). This version is a full frame version compared to the original video. The quality is much better and you can select resolutions all the way up to 4K 60fps (if you have the hardware to view UHD video that is). On YouTube you can't replace a video and keep the same URL link, so I'll leave both versions up on my YouTube channel.

Theoretically the dynamic range (ADC overload to noise floor) of an ADC is a little better than 6 dB * number of bits, which would be over 96 dB for a 16-bit ADC. But they are never that good in practice. I believe 90 dB is way optimistic, especially when you take into account the analog circuitry that is needed in front of the ADC. For example, the 16-bit LTC2107 from Analog Devices has 80 dBFS signal-to-noise ratio. Note that is a theoretical figure in that it assumes no degradation at all by external circuitry. This state-of-the-art device draws 1.28W of power and costs $99 in 1000-piece quantity. > Looking at S units, there is 88 db from S1 to 40 over S9 before any attenuation or > AGC is applied prior to the ADC. >> K3S K4HD Feature >> 24 16 ADC width As others have noted, that's an "apples and oranges" comparison because the 16-bit direct-sampling ADC is way oversampled compared to the 24-bit ADC at baseband or low-frequency IF. The S/N ratio of an ADC is improved by 10 * log(sample_rate/receive_bandwidth) dB For example, if the sample rate is 130 MHz and the receive bandwidth is 500 Hz, that's about a 54 dB improvement. If the ADC dyanamic range, including all external circuitry, is (let's say) 75 dB then the 500 Hz dynamic range is 129 dB. I think with current technology at reasonable cost, the high 120's dB is about the best you can do with a direct-sampling receiver and many don't do that well. By constrast, I believe the blocking dynamic range of a K3S is about 150 dB in a 500 Hz bandiwdth. I assume the K4 high-dynamic-range option will be similar. Whether you need the extra 20-30 dB of blocking dynamic range depends on your situation and what you plan to use the radio for.

That requires a very high speed ADC. In this case it is just above the Nyquist limit for 6 meters. Getting a 16 bit converter that fast approaches the limit of available technology. These converters are pipeline architecture and have better than 90 db dynamic range. Looking at S units, there is 88 db from S1 to 40 over S9 before any attenuation or AGC is applied prior to the ADC. The problem comes when there are signals exceeding that dynamic range like working someone who might be S1 or S2 while someone else is transmitting nearby as a direct conversion radio has no front end selectivity. As Eric already explained, this is the reason for the K4HD option. This appears to essentially be a K3S superhet single conversion front end that feeds an approximate 8 MHz IF into the ADC.

Since that IF bandwidth can be adjusted by xtal filters and will be MUCH narrower than 0.1 - 54 MHz it will also be far less susceptible to overload from strong signals not in that passband.?

The easiest solution is just to replace the encoder. I have repaired many KX1s, but only a few well used ones have had encoder problems, so I don't believe there is a "bad batch of encoders" in the KX1 history. Yes, yours was an early KX1. Look up the part number and description in the KX1 parts list and email it to parts at elecraft.com. You will receive a return email with the cost, and then you can order one using the Quick Order form on the website. 73, Don W3FPR On 5/29/2019 7:26 PM, ab2cj wrote: > All: > > I purchased a used KX1 and noticed that the rotary encoder behaves > erratically on occasion where it will momentarily fail to change > frequency when turning the knob. > > There's some play in the VFO shaft which maybe the cause of the problem. > The serial number is 666 which seems like an early model and I was > wondering if there's a history of a bad batch of encoders shipped at > that time?

Let me take a stab at some of these, and thanks to Alan, Jeff, and W2XJ for furthering my technical education about ADCs. (1) With direct sampling, if you are operating in a contest, you can keep an eye on other bands, like 10M in the current conditions, while operating on bands which have propagation. It's just another window on the screen. A superhet will severely narrow the bandwidth in the IF stages, so you need a separate superhet for each band (ala the 2nd receiver in the K3). (2) As far as I can tell, the K4HD should perform as well as a K3, or perhaps even better. Using the formula Alan posted, if I'm tuning a 4KHz FT8 band on a K4 with its 122 MHz sample rate, I will get a 44.8 dB improvement in S/N from the over sampling. I would get 47.6 dB for a 2.1 KHz SSB bandwidth and 60.8 dB for a 100 Hz CW bandwidth. (These are ranges I normally use in my operations.) Add the 77 to 85 dB range for a real 16 bit ADC with real support circuitry (these numbers are admittedly a WAG), and you get some pretty respectable performance. You also win big with the K4HD in the same way as with the K3. The IF filters greatly suppress signals not in the passband, such as that CW station in the tent next to your RTTY station, (which describes the WVARA QRP field day setup). (3) The details of the K3 ADC are beyond my current level of knowledge, but the documentation lists it as 24 bits, as does W2XJ's post. 73 Bill AE6JV On 5/29/19 at 4:01 PM, k6dgw at foothill.net (Fred Jensen) wrote: >I understand what direct sampling is and how it works.?

In some cases the counterpoise itself radiates more. On top of that, the SWR can vary all over the map depending on counterpoise characteristics and terrain. This is why the AXE1 literature will specify that an ATU is required. Under all but ideal static conditions, SWR is unpredictable and the ATU will be required for transmit matching. 73, Wayne N6KR > On May 29, 2019, at 4:56 PM, David Gilbert wrote: > > > It's not the takeoff angle that makes the difference here.

There are some subtleties in noise blanking that may distinguish the two modes (direct sampling or superhet). The blanking used in direct-sampling should have an advantage on complex, high-duty-cycle noise sources, while the hardware blanking modules used in the superhet may have an advantage with extremely short pulse sources.

Most line noise IS impulsive, and some noise blankers can be quite effective, but only if there are no strong signals nearby. I'm hoping a direct sampling receiver could avoid that problem. One method that has been used in the (distant) past was a second receiver tuned to a nearby but clear frequency to control the noise blanker. It seems that a direct sampling receiver ought to be able to do something like that. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From jim at audiosystemsgroup.com Wed May 29 23:12:55 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 29 May 2019 20:12:55 -0700 Subject: [Elecraft] K4HD question In-Reply-To: References: <5CEEE2EC.27414.AFFB029@Gary.ka1j.com> Message-ID: <379d3cec-da16-cdf7-211c-70ab3b1aebb2@audiosystemsgroup.com> On 5/29/2019 6:57 PM, Fred Jensen wrote: > Noise blankers were designed for repetitive impulse noise, the largest > former example of which was ignition noise from vehicles.?

The ARRL book on power line noise specifically states that virtually all power line noise is impulse noise, the result of arcing at positive and negative peaks of the 60 Hz line voltage. It is NOT random noise. It IS quite broadband. Arcing can also occur in big motors, or in any system where an arc occurs. BEFORE the days of microprocessors, switch-mode power supplies, and other power control systems that use square waves, nearly all man-made noise was impulse noise. NOW, most of the noise that surrounds us is from those microprocessors, switch-mode supplies, and other power control equipment. That noise is NOT impulse noise, and noise blankers cannot act on it. 73, Jim K9YC From k9ma at sdellington.us Thu May 30 00:45:15 2019 From: k9ma at sdellington.us (K9MA) Date: Wed, 29 May 2019 23:45:15 -0500 Subject: [Elecraft] K4HD question In-Reply-To: <379d3cec-da16-cdf7-211c-70ab3b1aebb2@audiosystemsgroup.com> References: <5CEEE2EC.27414.AFFB029@Gary.ka1j.com> <379d3cec-da16-cdf7-211c-70ab3b1aebb2@audiosystemsgroup.com> Message-ID: On 5/29/2019 22:12, Jim Brown wrote: > BEFORE the days of microprocessors, switch-mode power supplies, and > other power control systems that use square waves, nearly all man-made > noise was impulse noise.

I use the LP-Pan on 8.215 IF output of my K3 and that goes to the A/D in my Delta44 soundcard to provide a digital stream to sw in my computer. The 1st IF of the K3 is ahead of the roofing filters so fairly wideband. The LP-Pan is in fact a SDR which outputs IQ baseband to the soundcard. So with the K3 it is a single-conversion SDR. LP-Pan passes nearly 400-KHz of RF bandwidth which wider than most soundcards. The Delta44 is 96-KHz wide soundcard. Using a special eme sw all signals inside approx 90-KHz wide band are simultaneously decoded and displayed showing virtually all the calling stations. You could also say it displays as a 90-KHz panadapter. This sw has the ability to take two IQ streams so one can use the 1st IF of the subRx in the K3 simultaneously. With two antennas orthogonally polarized (Hpol and Vpol) the sw can actually solve for the real polarization angle and maximize the signal. So how does this relate to the K4? I'm guessing the A/D processing the panadpater display might also provide digital IQ output to a computer which could perform similar wideband decoding of digital signals. I guess the question would be if the IQ stream is available for export. 73, Ed - KL7UW From: Wayne Burdick To: Bill Frantz Cc: Elecraft Reflector Subject: Re: [Elecraft] 3 technical questions Message-ID: Content-Type: text/plain; charset=us-ascii The K4 is always doing direct sampling for panadapter purposes.

In general there is more immediate component heating on 6M for a given power (especially in the LPF and other areas outside of the PA transistors), so we start the fans at a lower heatsink temp. Also, when using very high dissipation modes like FT8 and JT65 on 6M at 1000-1500 W, we strongly recommend setting the minimum fan speed to at least 1 or 2. 73, Eric /elecraft.com/ ==== On 5/29/2019 1:08 PM, Richard Zalewski wrote: > Sorry for that...talking about my KPA1500. >>> On May 29, 2019, at 10:17 AM, Richard Zalewski >> wrote: >> >> Is fan speed band dependent as well as temp?

This is a relatively low resolution in today?s display environment compared to a current generation 12? laptops (such as the Dell Latitude) which has a default resolution of 1920 x 1080. Given the size of the monitor screen (10.5?) I also presume that there wouldn?t be much ?effective coverage? for displaying whatever software may be running. FWIW, I run a Dell Latitude laptop in my vehicle for a variety of data decoding purposes (primarily railroad signal data, EOT/HOT and distributed power unit transmissions) that decodes packets transmitted in the VHF and UHF bands using a variety of analog and SDR receivers. Being able to quickly scan a screen and not have to scroll the screen makes a huge difference in usability and safety. Whether there are 10-12? mobile monitors that can handle 1920 x 1080 is not something that I?ve looked for. Presumably this criteria would be something that would be needed in the instance you?re outlining. I would also suspect that whatever version of Linux may be in the K4, the real constraint would be how the effective capacity of the built-in system to manage the K4 to also handle non-K4 activities. I can tell you that the FlexRadio Systems Maestro has a built-in tablet display (apparently running a version of Windows) that has no provision for the user to run non-Flex software. If FRS were to add this capability, it would likely increase the cost of the product to provide a more robust tablet that could handle the appropriate data storage and presumably split-screen requirements. It would also introduce other potential issues in terms of security and the potential virus infection. Given that FRS controls ?firmware updates? for Maestro, their approach presumably reduces the prospects for nefarious intrusion. Also keep in mind that adding capabilities such as handling data streams for various comm programs may also increase the internet bandwidth requirements when operating remotely. I don?t know what the ?minimum? bandwith will be to operate a K4 remote system. The K3 & K3/IO-Mini system using Remote Rig has very low requirements given that there is no panadapter/waterfall display and only audio and control are exchanged between the two units with the audio codecs configurable to take into account internet upload limitations. Given that remote operation may entail low-speed internet (e.g. as noted during the Remote Operating Forum given Friday morning of the just concluded Hamvention, ?Locations with excellent internet service have poor RF conditions and locations with excellent RF conditions have poor internet service?), the ability to manage internet bandwidth in order to provide a reliable connection to operate is an important consideration. FRS has significantly improved their SmartLink system to work more effectively at slower upload speeds though it still requires more bandwidth than the K3 system (for obvious reasons-FRS has built-in Panadapter/Waterfall display).

Again, K3, KPA500 and KAT500. All are connected using AUX cables as described in the KPA500 and KAT500 manuals. KPA500 is STBY, and KPA500 NOT in any fault condition. K3 is transmitting at 100 watts, user taps the Operate button on the KPA500. The KPA500 decodes the button, then if RADIO is set to K3, it sends an auxbus message to the K3 indicating it is transitioning to OP mode. When the transmission of the message is complete, it then proceeds into Operate mode where it can process PTT input levels. The K3 will decode the auxbus message and set up to operate with the KPA.The KAT500 does not listen to KPA500 auxbus traffic; it does nothing (unless it see high SWR, of course). If RADIO is set to BCD (or something other than K3), then the auxbus message does not apply, and the KPA500 will immediately transition to Operate mode. When placed in operate mode the KPA500 is allowed to process PTT levels. Continuing your scenario, the KPA will then start sequencing the internal controls to switch to full transmit. This is a process that takes several milliseconds to complete (I?ll stop short of saying how many) and puts us in full transmit at the end of the sequence. I would expect that the K3 would have the time needed to drop its power to the requested level and we would keep going. This, of course assumes the K3 is set for Power per Band as described in the K3 manual. The KAT500 will not open the key line unless it sees high reflected power and needs to do something about it. I will have to test this to see exactly what happens, whether the KPA will fault or not. It is possible that the K3 processes the command quickly enough to drop power and things just keep going. My experience has been that Wayne is _really_ good at getting high performance out of the K3?s processor. I would not suggest trying this if at all possible. The stress the high power places on the input network will eventually cause damage to those components. While I enjoy visiting my friends in Watsonville, I don?t like bringing my radios down for them to be repaired (and thus not having their use)... And, Andy, I haven?t forgotten your other questions, I?ll get to them as soon as I can. 73!

It seems there is some risk that a fully integrated K3, KAT500, and KPA500 could experience a power spike for the scenario I proposed. Up to this morning I had been opening the KAT500 key line anytime my TS-590 was set to 40 W or more regardless of KPA500 mode. This is the pro-active overdrive protection I had previously told you about. With that implementation I saw a 600 W power spike when I selected OPER during an FT8 transmission with 37 W set for STBY but 8 W set as OPER band power. My setting of OPER band power will be much slower than the K3 response to the Aux bus signal. This morning I changed my controller code so KAT500 key line is always open when KPA500 is STBY. When I see KPA500 change to OPER I wait a second to allow OPER band power to be set and then enable the KAT500 key line. This greatly reduces the risk of a power spike at the STBY to OPER transition. Here is the diagnostic output for the transition 37 W STBY to 8 W OPER: 2:39:22.997 New KPA_mode - ^OS1; 2:39:22.998 STBY_OPER_time set 2:39:23.145 Sending PC008; to Kenwood 2:39:23.388 New PC - PC008; 2:39:23.999 power_prot_limit=40 2:39:24.000 Power protection cleared 2:39:24.001 KEN power verified 2:39:24.003 Sending AMPI0; to KAT500 2:39:24.062 New AMPI - AMPI0; My power management code is not all that complex but it has taken a while to understand and accommodate the various "corner cases". Your willingness to share your insights has been helpful. 73, Andy, k3wyc From vetterestorer at gmail.com Thu May 30 19:20:14 2019 From: vetterestorer at gmail.com (DC) Date: Thu, 30 May 2019 16:20:14 -0700 Subject: [Elecraft] K3 Help need to buy old style K3 synthesizer In-Reply-To: <3E3F8789-0E6B-4C84-9F85-950CCA575F0E@elecraft.com> References: <00bc01d516ce$ed3427f0$c79c77d0$@qrv.com> <3E3F8789-0E6B-4C84-9F85-950CCA575F0E@elecraft.com> Message-ID: <23e3ec4d-1f87-5c5f-d10f-b90eeb6d2203@gmail.com> All: I just had the synthesizer on my K3 stop working.?

If the part that is built into the K3, I would strongly suggest getting the part direct from Elecraft. These have to be securely mounted within the radio. If the part that connects, note the following: PowerPole connectors come in sizes according to the current amperage required for the particular circuit. Anderson PowerPoles consist both of the red and black housing and the crimp connectors for the wires. The housing size used in the K3 is the standard size that will fit both 15, 30 and 45 amp crimp connectors. You choose the connector that fits the particular wire size. 30 amp capacity circuits are adequate to power the K3 and should be used. Unless you purchase pre-assembled connectors you will also need a crimp tool to crimp the connectors to the wires. There is also a small learning curve on how to crimp and insert the crimped wires into the housings. I would get the parts you need from a company such as Powerwerx. They can help with any connections. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Lee Trout Sent: Friday, May 31, 2019 8:12 AM To: Elecraft Reflector - post Subject: [Elecraft] K3 PowerPole connector I am looking to replace the powerpole connector on my K3.

The advantage of doing this on the LCD rather than with hard switches is that we can provide different arrangements depending on the operator's needs. For example, the op may want more transverter controls, may not use the WARC bands during contesting, or might prefer to dedicate one or more switches to specific frequencies. If a new band is allocated in the future -- perhaps limited to a subset of countries -- we'll be able to add it with a software update. Band-stacking depth will be adjustable. 73, Wayne N6KR > On May 31, 2019, at 9:00 AM, dhhdeh wrote: > > I owned a K3 from February 2008 until mid-2015. > > One of the its UI features that I could never warm up to was the lack of dedicated band switching buttons and multiple band stacking registers. > > Can someone please give some insight on how the band button below the K4 screen works and its capabilities? > > Thanks and 73 de N1LQ-Dave > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html From n6kr at elecraft.com Fri May 31 12:19:31 2019 From: n6kr at elecraft.com (Wayne Burdick) Date: Fri, 31 May 2019 09:19:31 -0700 Subject: [Elecraft] K4 VFO B Front Panel Positioning In-Reply-To: <6a0cbe8f-abfb-1e29-956e-006ab8e89a90@comcast.net> References: <6a0cbe8f-abfb-1e29-956e-006ab8e89a90@comcast.net> Message-ID: Dave, Here's what I posted earlier: * * * Based in part on a survey of potential users, we chose to put the RIT/XIT knob at bottom right -- also a traditional location, one that matches that of the K3/K3S/KX2/KX3. VFO B is less often used in practice. That said, the radio is only 4.5" tall and both knobs are very comfortably used in these locations. * * * I use the K4 every day and find the control locations work well.

You can then select one. We'll also provide an alternative behavior for the MODE switch for ops who use only CW and SSB (for example): tapping MODE will just alternative among 2 or 3 specific modes. This will eliminate the need to tap the mode buttons on-screen. The *hold* function of the MODE switch is "ALT", as on our other rigs. This alternates between USB and LSB, CW-normal/CW-reverse, AM/AM-sync, etc. Each VFO has its own mode identifier.

I have installed Powerpole plugs without the crimper however the crimper is a nice tool to have. You can purchase custom cables already made from Powerwerx of you don't wish to make them. The 30 amp plug is adequate however the 45 amp plug will allow using a larger conductor. To minimize voltage drop you should use a very large cable, I use 8 awg when my power supply is set up on the floor. John KK9A George Thornton wrote: Are you replacing the connector that plugs into the K3 or are you replacing the part built in to the K3? If the part that is built into the K3, I would strongly suggest getting the part direct from Elecraft. These have to be securely mounted within the radio. If the part that connects, note the following: PowerPole connectors come in sizes according to the current amperage required for the particular circuit. Anderson PowerPoles consist both of the red and black housing and the crimp connectors for the wires. The housing size used in the K3 is the standard size that will fit both 15, 30 and 45 amp crimp connectors. You choose the connector that fits the particular wire size. 30 amp capacity circuits are adequate to power the K3 and should be used. Unless you purchase pre-assembled connectors you will also need a crimp tool to crimp the connectors to the wires. There is also a small learning curve on how to crimp and insert the crimped wires into the housings. I would get the parts you need from a company such as Powerwerx. They can help with any connections. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Lee Trout Sent: Friday, May 31, 2019 8:12 AM To: Elecraft Reflector - post Subject: [Elecraft] K3 PowerPole connector I am looking to replace the powerpole connector on my K3.

I have several more of a secondary nature to ask for now. Thanks for taking the time. -Will the shift/width and lo cut/hi cut functions be on the K4 similar as with the K3, or does the nature of the direct sampling IF architecture make that no longer available? -I notice a CW APF circuit is installed. Is it a variable width and how is that performed? -Is the screen exclusively a touch screen or can screen functions also be mouse controlled? -Does the DVR permit recorded QSO playback over the air as with the K3? -Any estimate as to when a user manual will become available to study?

The RigPi is 4 parts - Rpi, windkeyer card, audio card, and software. I now have it setup on a Rpi I already owned with generic USB audio dongle connected to headphone jack and mic on radio. Works fine. I don?t intend to use for CW so I will soon be listing my MFJ-1234 for sale on QRZ. I don?t need the data cable because audio from it is not processed and not acceptable for SSB. Software is excellent with low latency on CAT. Audio is carried via Mumble server which is pre-configured in software. You will need to download/setup the Mumble client for remote. So if you want to do SSB on the cheap- just buy the software. Very good docs at rigpi.net/help which should answer most.

I have done the power supply rebuild, the soft-start and other mods. I have also directly grounded the grids of the 3-500Zs (Eimac brand). In driving it with my K3 (SN 51XX, software up to date) I find that the RF power stair-steps to the set power in a hesitating way over a few seconds. This happens sending Morse code or using the "Tune" button. The supply voltage, as monitored on the K3 display, is at about 13.4 volts when transmitting. I have a power/SWR meter between the K3 and the amp and it shows a low SWR at all times, as does the K3 SWR meter. The power meter between the K3 and the amp shows the power gradually increasing. As the K3 increases power out, the amp power out increases in a similar fashion. I see no indication of oscillation. The power meters on the output side of the amp show no power when the amp is keyed but no RF is supplied. I placed a low-pass filter (41 MHz cutoff) between the K3 and the amp to no effect. I notice that if I send a series of Morse code characters such that the K3 transmit delay timer never times out, once the power ramps up to the set value, it remains solid until the timer expires - when I start transmitting again, the power step process repeats. When I put the amp in Standby, the K3 functions normally. This smells like an oscillation problem, but I see no evidence of one. Any advice would be appreciated.

It is stranded with much finer / smaller wire than THHN and is much more flexible than THHN. ?? It does correctly fit the 30 amp PowerPole connectors thus no splicing is needed or as suggested. I also recommend not only correctly crimping the PowerPole pins but carefully flow solder into the sleeves.?? Likewise on the other end, the correct size ring terminal should be used, crimped and soldered, for the power supply connections. The transceiver power should come direct from the power supply, thus avoiding any DC distribution panels. 73 Bob, K4TAX From rmcgraw at blomand.net Fri May 31 20:18:19 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Fri, 31 May 2019 19:18:19 -0500 Subject: [Elecraft] Problem with K3 driving old tube amp In-Reply-To: References: Message-ID: Sounds as though ALC from the amp is causing the transceiver to step power.??
