I have 2 APC UPS devices - I moved one's 7 AH battery to an external container where I have three of them in parallel. That UPS runs the cable modem, router, and cordless phone system. The other one runs my desktop computer and accessories. Because of the type of battery in the machine, I would have to do serious soldering to attach external wires, which would void the warranty. My standby power mentor/guru explained to me quite a few years ago that given a large enough battery source, the limiting factor in most consumer-grade UPS is the heating of the electronics. Both of those UPSes are running at about 15% of "advertised capacity" which, according to APC's runtime curve, extends the run time by a factor of 10. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From kk5f at earthlink.net Fri Sep 1 00:56:39 2017 From: kk5f at earthlink.net (Mike Morrow) Date: Thu, 31 Aug 2017 23:56:39 -0500 (GMT-05:00) Subject: [Elecraft] KX2, spy radio Message-ID: <20263843.13890.1504241799987@elwamui-hound.atl.sa.earthlink.net> Here's a 1970-era small western world 'clandestine' set called the AVCO TAR-224A: http://www.cryptomuseum.com/spy/tar224/ It's about three times the bulk of the KX3, which is very small for the era and not too large even by today's standards. It puts out 20 watts A1 or A3 from 2 to 24 MHz, and is all solid state with auto antenna tuner and Morse key built onto the front panel. (Sounds familiar.)

I had a SmartUPS 750, and it was very bad. Put out crud all the way from VLF to VHF. I threw it away in the end.

When you get into the larger UPSes, they might want to charge really fast, but charging at a high rate and carrying the rated load will exceed 12 amps. So depending on the rating of the unit, and the recommended input circuit, some models will definitely charge slow. 16 hours is not too fast for charging. If the UPS can't carry the load for ten hours, then the discharge rate is WAY TOO FAST. Most UPSes are designed to carry the load for about 15 minutes, so if you aren't killing the battery charging, you're killing it discharging. 73 -- Lynn On 9/1/2017 10:32 AM, Phil Kane wrote: >> Second, a local computer guru, AE6KS, has observed that most UPS mfrs charge batteries at too fast a rate for good battery life. > Both spec sheets show a recharge time of 16 hours.

IMO, power amps are totally out of place on FD, which I've always seen as a "barefoot" or QRP event. We do county expeditions for QSO parties like 7QP and CQP, and run two or three stations, each consisting of a K3, KPA500, KAT500, and P3/SVGA. Each station is powered by a Honda 2000i running in Econmode. They make some RF noise, which must be filtered with a good multi-turn ferrite choke. Follow the guidelines for chokes on RG8-size cable (k9yc.com/RFI-Ham.pdf), and place the choke right at the generator. Commercial line filters do NOT work. My neighbor W6GJB converted his 2000i to propane, and loves it. Mine is still burning petrol. 73, Jim K9YC On 9/1/2017 10:37 AM, Michael Chowning wrote: > Being there is no better place to get advice than this reflector, I am seeking your recommendation.

Little worried after I read this review: http://ve3vn.blogspot.se/2015/02/kx3-review-by-qrp-dxer-and-contester.html Is any chance for Elecraft to make (KIT UPDATE) for XV144 to use IF on 14MHz, the most transceivers has much better characteristic on 14MHz then on 28MHz. One can choose if they want to make XV144 with 28 or 14MHz IF, depending on use (CW, SSB, FM). 73' Samir, sm7vzx From marklgoldberg at gmail.com Fri Sep 1 16:13:07 2017 From: marklgoldberg at gmail.com (Mark Goldberg) Date: Fri, 1 Sep 2017 13:13:07 -0700 Subject: [Elecraft] Portable Power for digital and Phone operation In-Reply-To: References: Message-ID: On Fri, Sep 1, 2017 at 10:37 AM, Michael Chowning wrote: > Being there is no better place to get advice than this reflector, I am > seeking your recommendation.

The inverter generators are quiet though. I have been threatened that my RV generator will suffer from "Lead Poisoning" if it is run in the woods.

A description with specific models may be found on: https://sites.google.com/site/marksrvmods/ The RV has a large inverter for 115V. I previously used a large inverter standalone. Both are Xantrex, a good brand. They make some RF hash, but they are tamable with Ferrite cores. Some inverters are very noisy. 200W of solar panels and two 75 Amp Hour batteries will run a 100W ham station for field day late into the night. I have 4 batteries and 400W of solar panels to run the RV too. I am really keen on the flexible solar panels I use. They are very light and efficient. They have gotten lots of attention whenever I set them out. They may not be the best for a permanent installation, but for quick setup and teardown they are ideal. Note that MPPT solar charge controllers are the most efficient but usually make lots of RF hash. I use a Morningstar PWM controller that has a bang bang option, that will either be on or off, no RF hash from switching. It does reduce the actual output of the 400W panels to 300W though. Lipo batteries do not produce the right voltage for radios. 4 Cells is too much, 3 cells is too little. LiFePO4 batteries do and they are safer. A 4 cell pack runs from about 14.4 V down to 12 V at 90% discharge, which is ideal for remote operation. They still take special charging, sometimes built in to the batteries, but they are very expensive. I have a 20 Amp Hour from batteryspace,com that I use for long QRP, and I have a separate special charger. They also have ones with built in charging / balancing circuits, but they cost more. I have two small 4s1p LiFePO4 packs from buddyrc.com for remote QRP, but they don't seem to sell them any more. bioennopower.com has lots of options with built in charging circuits that make it a little easier and they get good reviews. I could not afford to have the big boys be LiFePO4 though and have not bought from them. A few hundred Amp Hours of LiFePO4 will be in the thousands of dollars. For all these batteries, it is a good idea to monitor them and stop using them when they get down to about 12V. LifePO4 especially can be permanently damaged if discharged too low. Good luck in whatever you choose. As you can see, there are many options with no "best" option for all circumstances. 73, Mark W7MLG From n6kr at elecraft.com Fri Sep 1 16:31:00 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Fri, 1 Sep 2017 13:31:00 -0700 Subject: [Elecraft] Update on KXPD2 and KXPD3 paddles Message-ID: <53E6D35C-05DC-4292-A3CE-20698842B640@elecraft.com> I have to apologize for stating that there were mod kits available for the KXPD2 and KXPD3 that reflect improvements we?ve made over time.

For paddles under warranty that aren?t up to the current configuration, we?ll add the upgrades on request, at no charge. For those out of warranty, we charge a flat $79 fee (plus shipping) to do the upgrade. (We just reduced this from $95.) If you have an older KXPD3 you?d like to upgrade, please use the following link to place the order: http://www.elecraft.com/order_form_parts.htm#kx3 For older KXPD2s there will be a similar process, but it is not in place yet.

I have 2 APC UPS devices - I moved one's 7 AH battery to an external container where I have three of them in parallel. That UPS runs the cable modem, router, and cordless phone system. The other one runs my desktop computer and accessories. Because of the type of battery in the machine, I would have to do serious soldering to attach external wires, which would void the warranty. My standby power mentor/guru explained to me quite a few years ago that given a large enough battery source, the limiting factor in most consumer-grade UPS is the heating of the electronics. Both of those UPSes are running at about 15% of "advertised capacity" which, according to APC's runtime curve, extends the run time by a factor of 10. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ------------------------------ Message: 4 Date: Thu, 31 Aug 2017 23:56:39 -0500 (GMT-05:00) From: Mike Morrow To: Elecraft at mailman.qth.net Subject: Re: [Elecraft] KX2, spy radio Message-ID: <20263843.13890.1504241799987 at elwamui-hound.atl.sa.earthlink.net> Content-Type: text/plain; charset=UTF-8 Here's a 1970-era small western world 'clandestine' set called the AVCO TAR-224A: http://www.cryptomuseum.com/spy/tar224/ It's about three times the bulk of the KX3, which is very small for the era and not too large even by today's standards.

I had a SmartUPS 750, and it was very bad. Put out crud all the way from VLF to VHF. I threw it away in the end. In the shack I use a much older APC Back-UPS 500 for the computer, which doesn't seem to cause any problems. I've had to replace the battery every 3-4 years, but that's to be expected. 73, Richard G4DYA ------------------------------ Message: 9 Date: Fri, 1 Sep 2017 20:04:58 +1000 From: Glen Torr To: Elecraft Reflector Subject: [Elecraft] The times they are a changin.

The real use of SSB came when General LeMay of SAC adopted it for their world wide HF communications network and propagation conditions during that time were so good that it was almost impossible NOT to communicate anywhere you wanted to with SSB.

When you get into the larger UPSes, they might want to charge really fast, but charging at a high rate and carrying the rated load will exceed 12 amps. So depending on the rating of the unit, and the recommended input circuit, some models will definitely charge slow. 16 hours is not too fast for charging. If the UPS can't carry the load for ten hours, then the discharge rate is WAY TOO FAST. Most UPSes are designed to carry the load for about 15 minutes, so if you aren't killing the battery charging, you're killing it discharging. 73 -- Lynn On 9/1/2017 10:32 AM, Phil Kane wrote: >> Second, a local computer guru, AE6KS, has observed that most UPS mfrs charge batteries at too fast a rate for good battery life. > Both spec sheets show a recharge time of 16 hours.

IMO, power amps are totally out of place on FD, which I've always seen as a "barefoot" or QRP event. We do county expeditions for QSO parties like 7QP and CQP, and run two or three stations, each consisting of a K3, KPA500, KAT500, and P3/SVGA. Each station is powered by a Honda 2000i running in Econmode. They make some RF noise, which must be filtered with a good multi-turn ferrite choke. Follow the guidelines for chokes on RG8-size cable (k9yc.com/RFI-Ham.pdf), and place the choke right at the generator. Commercial line filters do NOT work. My neighbor W6GJB converted his 2000i to propane, and loves it. Mine is still burning petrol. 73, Jim K9YC On 9/1/2017 10:37 AM, Michael Chowning wrote: > Being there is no better place to get advice than this reflector, I am seeking your recommendation.

A description with specific models may be found on: https://sites.google.com/site/marksrvmods/ The RV has a large inverter for 115V. I previously used a large inverter standalone. Both are Xantrex, a good brand. They make some RF hash, but they are tamable with Ferrite cores. Some inverters are very noisy. 200W of solar panels and two 75 Amp Hour batteries will run a 100W ham station for field day late into the night. I have 4 batteries and 400W of solar panels to run the RV too. I am really keen on the flexible solar panels I use. They are very light and efficient. They have gotten lots of attention whenever I set them out. They may not be the best for a permanent installation, but for quick setup and teardown they are ideal. Note that MPPT solar charge controllers are the most efficient but usually make lots of RF hash. I use a Morningstar PWM controller that has a bang bang option, that will either be on or off, no RF hash from switching. It does reduce the actual output of the 400W panels to 300W though. Lipo batteries do not produce the right voltage for radios. 4 Cells is too much, 3 cells is too little. LiFePO4 batteries do and they are safer. A 4 cell pack runs from about 14.4 V down to 12 V at 90% discharge, which is ideal for remote operation. They still take special charging, sometimes built in to the batteries, but they are very expensive. I have a 20 Amp Hour from batteryspace,com that I use for long QRP, and I have a separate special charger. They also have ones with built in charging / balancing circuits, but they cost more. I have two small 4s1p LiFePO4 packs from buddyrc.com for remote QRP, but they don't seem to sell them any more. bioennopower.com has lots of options with built in charging circuits that make it a little easier and they get good reviews. I could not afford to have the big boys be LiFePO4 though and have not bought from them. A few hundred Amp Hours of LiFePO4 will be in the thousands of dollars. For all these batteries, it is a good idea to monitor them and stop using them when they get down to about 12V. LifePO4 especially can be permanently damaged if discharged too low. Good luck in whatever you choose. As you can see, there are many options with no "best" option for all circumstances. 73, Mark W7MLG ------------------------------ Message: 26 Date: Fri, 1 Sep 2017 13:31:00 -0700 From: Wayne Burdick To: Elecraft Reflector Cc: "KX3 at yahoogroups.com" Subject: [Elecraft] Update on KXPD2 and KXPD3 paddles Message-ID: <53E6D35C-05DC-4292-A3CE-20698842B640 at elecraft.com> Content-Type: text/plain; charset=utf-8 I have to apologize for stating that there were mod kits available for the KXPD2 and KXPD3 that reflect improvements we?ve made over time. Turns out that we only upgrade existing units at the factory, so we can do complete testing before returning them. For paddles under warranty that aren?t up to the current configuration, we?ll add the upgrades on request, at no charge. For those out of warranty, we charge a flat $79 fee (plus shipping) to do the upgrade. (We just reduced this from $95.) If you have an older KXPD3 you?d like to upgrade, please use the following link to place the order: http://www.elecraft.com/order_form_parts.htm#kx3 For older KXPD2s there will be a similar process, but it is not in place yet. We?ll announce it in a week or two. 73, Wayne N6KR ------------------------------ Message: 27 Date: Fri, 01 Sep 2017 20:41:38 +0000 From: "Yngvi (TF3Y)" To: "Elecraft at mailman.qth.net" Subject: [Elecraft] Bluetooth audio adapter for K3 Message-ID: Content-Type: text/plain; charset="UTF-8" Has anyone used a Bluetooth adapter for wireless headphones / headset with the K3?

There have been many thoughtful and detailed posts on this topic in the last six months.

We?re also going to make a minor change to the PCB. In general the changes would not be noticeable by the average user. But we have SOTA operators who are using them in very harsh conditions, and over time we?ll probably refine things based on their feedback. In general, if you feel that something isn?t working perfectly, please contact customer support so they can assess what the issue may be. 73, Wayne N6KR > On Sep 1, 2017, at 3:43 PM, Roger Meadows wrote: > > How do we tell if our current KXPD2 is up to the current configuration? > > Roger > AE4RM > >> On Sep 1, 2017, at 4:31 PM, Wayne Burdick wrote: >> >> I have to apologize for stating that there were mod kits available for the KXPD2 and KXPD3 that reflect improvements we?ve made over time.

You need to have a separate (receive only) antenna connected directly to the subreceiver's auxiliary antenna input, which I believe in your case is the K3S's ANT2 jack (depends on how you have chosen to configure the subRX's aux RF input). 73, Rich VE3KI N4SRN wrote: I getting to setting up my my K3S/100 with internal ATU with a KPA500/KAT500.

Indeed it is, Ian.? And superior in many ways to very expensive lab equipment, particularly in its frequency resolution. And the SVGA, which does an even higher resolution FFT, significantly improves that resolution.? To see examples of how it can be used as a test instrument, see http://k9yc.com/FTDX5000_Report.pdf Note also that even very inexpensive modern SDR receivers have excellent spectrum analysis capabilities, but, like the K3/P3, must be properly calibrated.

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

The K3 NB is really TWO blankers, operating in two different IFs. Each can be tweaked for various kinds of noise from the menu system.? Access the menu by a Long Push of the NB button. It's important to understand that there are many kinds of noise. Noise blankers are most effective on IMPULSE NOISE, which is the result of something arcing, usually in the power system, but also electric fences and neon signs. Most of the residential noise we hear today is ELECTRONIC noise, generated by switch-mode power supplies and microprocessors.? Noise blankers must be very different to suppress this sort of noise. The menu tweaks provided by the K3, K3S, KX3, and KX2 are very critical to making the NB effective on the noise you're experiencing. One size does NOT fit all. 73, Jim K9YC >> On Sep 3, 2017, at 10:37 AM, Rick Tavan wrote: >> >> Noise blankers are difficult to design and to use.

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

I also find that adjustment is highly dependent on the characteristics of the signal and the noise, and the effects of changing those adjustments is subtle.? The effect of a blanker on ignition noise was really astounding ... "was," because ignition noise seems to be history these days.? I suspect that many of the "it doesn't work very well" observations may stem from anticipation of a dramatic disappearance of today's noise from incidental and unintended radiators with NB on.? My local noise comes from the NV Energy power system and an uncountable number of Part 15 violators in the house and neighborhood.? K3 NB is very effective for me against them. I am a bit sorry that both the IF and DSP blanker parameters are so cryptic in the K3.? Depth of the blanking pulse and width of the blanking interval are the two "real" parameters involved.? The K3 seems to camouflage them which, for me at least, makes them a bit harder to adjust properly, I'm not sure what I'm doing when I change them.? Incidentally, punching holes in the receiver sensitivity to block noise pulses is itself introducing noise.? As with everything else in life, it's a trade-off. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/3/2017 9:40 AM, Jim Brown wrote: > On 9/3/2017 9:18 AM, K9MA wrote: >> I have never found the K3 noise blanker to be effective. > > >> BTW, the K3 noise blanker uses a filter with a bandwidth of about 100 >> kHz. > > > The K3 NB is really TWO blankers, operating in two different IFs.

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

In the K3(S) there is no "RF Gain" control unless by RF gain you mean "It's not the audio gain gain control."

It removes power line noise by muting reception 120 (or 100) times a second, corresponding to peaks in the power line voltage when the arcing occurs. If you chop an audio tone up at 120 Hz, you are amplitude modulating the tone with a 120 Hz waveform. That produces sidebands either side of the tone 'carrier'. This is why you should never use a noise blanker with FT8 and similar modes. The best way to use a rig with WSJT-X is, generally speaking, to make the computer do as much as possible and make the rig do as little as possible. Treat it more or less as a dumb transverter. Don't use the noise blanker, don't reduce the bandwidth below about 2.5 kHz, don't use the notch filter. WSJT-X's decoder works best if you just get the level about right and let it deal with the QRM. 73, Richard G4DYA From k9yeq at live.com Sun Sep 3 18:34:50 2017 From: k9yeq at live.com (Bill Johnson) Date: Sun, 3 Sep 2017 22:34:50 +0000 Subject: [Elecraft] MH4 Microphone Questions In-Reply-To: <4188BE6D-4ADE-4724-B5EF-C77ECE7DCFB7@elecraft.com> References: <484482972.1968836.1504444184457.ref@mail.yahoo.com> <484482972.1968836.1504444184457@mail.yahoo.com> <4188BE6D-4ADE-4724-B5EF-C77ECE7DCFB7@elecraft.com> Message-ID: Wayne, will you offer a mic adapter to also use with KX@ and KX3? 73, Bill K9YEQ -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wayne Burdick Sent: Sunday, September 3, 2017 3:05 PM To: Steve Kavanagh Cc: Elecraft Reflector Subject: Re: [Elecraft] MH4 Microphone Questions > On Sep 3, 2017, at 6:09 AM, Steve Kavanagh via Elecraft wrote: > > I find the MH2 a bit on the large side for my hands, so the MH4 looks interesting to me.

The PTT connection would be easy (PTT goes to ground), but if you also wanted the UP and DN buttons to work, you would have to add some level sensing circuitry whose outputs would be connected to the UP and down input pins on the Foster connector. Look at the schematic of the KX2/KX3 mic connections and compare the output to the pinout of the K3(S) mic connector and you will see the difficulty. So I think the adapter that you have suggested would not be practical for the KX2/KX3. 73, Don W3FPR On 9/3/2017 6:34 PM, Bill Johnson wrote: > Wayne, will you offer a mic adapter to also use with KX@ and KX3?

Rather, it's clearly just a technique that is not for everyone. AGC will reduce the gain according to the strongest signal inside the I.F. passband. Manually riding the "RF" gain ensures that a very weak signal is not affected by a strong signal that is also inside the I.F. passband. Of course that means your ears could be blasted by that strong signal, which is why Wayne included a hard limiter that can be enabled to chop such a signal down to size, making it no louder than the weak signal we want to copy. It has become a moot point for many operators today who cannot read CW if they are hearing two or three (or more) signals within the I.F. passband all at the same time. For them, it's essential to have enough I.F. selectivity to isolate one signal and so AGC is just fine. But some of us have a lifetime of experience sorting out multiple signals with our gray matter between the ears and prefer to continue to do so -- probably until we all become SKs. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wes Stewart Sent: Sunday, September 3, 2017 3:00 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Noise Blankers Just a couple of points.

The HRO receivers have the large dial which at that time provided good dial reading vs. frequency readings. That was done with a chart of frequency vs. dial number, and with Elecraft gear, that is done in firmware with the display showing the actual frequency without reference to a graph. There is a crystal filter in the HRO, but it is not like the filters in the Elecraft gear - in those old days, you had to adjust the crystal phasing to peak the signal and it was only useful for CW. I don't know which HRO receiver you are referring to. There is a big difference between them, culminating with the HRO50. My experience with National receivers goes back to the NC-100 which was the predecessor to the HRO series, and has the bandswitching system of the NC-240D (I still have it in the attic - a restoration project for "someday-maybe", but it may never actually happen). 73, Don W3FPR On 9/3/2017 1:46 PM, Doug Millar via Elecraft wrote: > For fun- What technical design technique does the National HRO receiver series? have in common with the Elecraft series of receivers that is unique to both of them??

KD5ONS From n4uw at chartertn.net Sun Sep 3 20:32:55 2017 From: n4uw at chartertn.net (Luther Phillips) Date: Sun, 3 Sep 2017 20:32:55 -0400 Subject: [Elecraft] OT - WSJT-X & K3s Message-ID: <3110E1C232AF4089A0067C71BCF94F9F@LPBStar> My software setup with a K3S, LP-Pan, and Asus U5 is as follows: LP-Bridge creating virtual ports for: NaP3 CW Skimmer Ham Radio Deluxe (last free version, 5.0 Build 2893, using the Logbook as my main log) N1MM or WriteLog for contests Note that HRD versions newer than about 6.2 will not work with LP-Bridge. I am able to run WSJT-X V1.8 rc2 & JT Alert by selecting Ham Radio Deluxe as the radio in WSJT-X, which connects it to the HRD server port. Sometimes changing bands from WSJT-X takes two tries, but otherwise it works fine, even in split TX mode. I'm also using the USB sound card in the K3S for the audio in to WSJT-X. Works great, I've seen decodes down to -26 to -28 in JT65 & JT9. JT Alert automatically sends the info for each contact to HRD Logbook when the 73 message is sent, or you can send it manually. If you haven't upgraded WSJT-X to the new 1.8 rc2 version, you should do so if you are using it for FT8. There are a number of significant FT8 improvements in rc2. There is a WSJT-X user group on Yahoo. Win4K3 also provides virtual ports and a HRD server port, maybe WSJT-X would connect to its HRD server. I have not tried that method. Hope this is of some help. 73, Luther N4UW From w3llbud at gmail.com Sun Sep 3 20:37:12 2017 From: w3llbud at gmail.com (Bud Governale, W3LL) Date: Sun, 3 Sep 2017 20:37:12 -0400 Subject: [Elecraft] K3 Jumps To High Output In Data Mode During Power Knob Rotation Message-ID: <823729C75B7446CE8BAE9ACB5C5AA246@Bud2> The K3 mode button is set to DATA and the transmit mode is DATA A. As I adjust the power output (PWR) knob during continuous transmit, the measured output displayed on the Power Master jumps to a high level. As an experiment, If the output is at a steady 40 W for example, when I slowly and continuously rotate the PWR knob, the output jumps to 150+ watts output during rotation of the PWR knob. As soon as I stop rotating the PWR knob the output is steady at the chosen output. If I choose a different power output during receive, the output is momentarily very high and then drops to the selected output ? Overshoot. No Overshoot if I don?t change the PWR knob. This is causing havoc with the amp. Out of curiosity I tried this in CW mode. In CW when I turn the PWR knob during a continuous transmit, the output does not jump to a high level but rather it follows the PWR knob setting smoothly. What may be the issue? 73, Bud W3LL W3LL at ARRL.NET From drzarkof56 at yahoo.com Sun Sep 3 20:45:41 2017 From: drzarkof56 at yahoo.com (Doug Millar) Date: Mon, 4 Sep 2017 00:45:41 +0000 (UTC) Subject: [Elecraft] What technical similarity do HRO receivers and Elecraft receivers share that is unique? - Answer References: <409844036.2082948.1504485941147.ref@mail.yahoo.com> Message-ID: <409844036.2082948.1504485941147@mail.yahoo.com> Hi Don and others- ?

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

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

In the HRO they had clips you could change over to go to "bandspread" mode on each coil assembly, Elecraft uses relays (switches) to change capacitor values in their bandpass filters so that the same assembly can cover two ranges. Essentially the same thing. I don't think any other companies have used this technique as extensively as National and Elecraft. Your opinion may vary......... Doug Dr.Doug Millar EdD.

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

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

Manually riding the "RF" gain ensures that a very weak signal is not affected by a strong signal that is also inside the I.F. passband. Of course that means your ears could be blasted by that strong signal, which is why Wayne included a hard limiter that can be enabled to chop such a signal down to size, making it no louder than the weak signal we want to copy. > > It has become a moot point for many operators today who cannot read CW if they are hearing two or three (or more) signals within the I.F. passband all at the same time.

In this regard, it is little different from AGC, which operates on exactly the same circuitry. Why some people believe that they are better at controlling i-f gain than the AGC system does is beyond me, but old wife's tales die hard.

When I have the K3S power knob set, in this case, to show 420-440W peak-hold as read on the KPA500 LED screen, I see the KPA500 SWR showing 1-3 LEDs lit (it may stay at 1 LED or climb from 1 to 3 LEDs over 15sec TX, always below 1.5), the KAT500 with SWR 1.2 LED lit, and P3TXMON indicating SWR 1.00 (it might start at 1.15 and settle back to 1.00 over 15sec TX). But PEP on the P3TXMON can range from 10-15W up to ~400W on successive 15sec periods of TX using WSJT-X FT8 (going for very distant CQs). Adjusting the K3S power knob down may bring P3TXMON displayed power up if its 10-15W. If the P3TXMON shows 200W adjusting the K3S power knob up may bring the P3TXMON power shown down. Is that how it's supposed to work?

My tuning practice is to change Frequency, turn KAT500 to BYP, tune the remote ATU, then set KAT500 to AUTO and let it adjust on 1st TX.

The KPA500 measures the signals it sees going into the KAT500, while the KAT500 measures what it sees going into the choke. Finally, the P3TXMON?s coupler measures what it sees going into the coax going to the SG-235. It is quite probable they will actually see different things. To make matters worse, you are trying to take measurements with a varying signal. You really want to step back and make the measurements with a steady signal (CW, key down) to see what is really happening. But when you do, be aware of what is happening in the SG-235. While the SGC literature says it is rated for 500W SSB, the important line says only 200W continuous. That means at 500W there is quite about of heating occurring in the toroid cores in the tuner. They won?t have much of any time to cool down between transmissions (SSB has very low peak to off times). Much of this and you will see the P3TXMon and KAT500 reading skyrocket and then will send the SGC in for repairs. If you intend to keep this setup, dial the K3S power down so that the SGC really only sees 200 watts, test everything at that level, then don?t change power levels when you switch to the digital mode. Also, you might want to move the choke to the output side of the P3TXMon pickup unit.The choke is designed to clear up currents on the outside of the coax shield (which you don?t want for reasons others will most likely explain). You are exposing the P3TXMON to these currents and probably adversely affecting its measurements. Make that change and the P3TXMON and KAT500 readings should become a bit closer. And remember to do all this at CW. Taking measurements with a varying signal can introduce interesting issues in the measurements themselves. The issue has to do with when the two signals (forward and reflected voltage) are actually measured. Unless they are simultaneously measured, then you won?t get precise values unless the signal is steady-state. I suspect you are running into a bit of this also. - Jack, W6FB > On Sep 4, 2017, at 5:06 AM, MaverickNH wrote: > > I'm learning about a new KPA500/KAT500 installed with my K3S.

Of course that means your ears could be blasted by that strong signal, which is why Wayne included a hard limiter that can be enabled to chop such a signal down to size, making it no louder than the weak signal we want to copy. > From cbjesseenh at comcast.net Mon Sep 4 12:26:50 2017 From: cbjesseenh at comcast.net (Charles) Date: Mon, 4 Sep 2017 16:26:50 +0000 (UTC) Subject: [Elecraft] [KPA500] K3S/KPA500/KAT500 - Adjusting TX Power In-Reply-To: <2CB71C2C-D109-475E-B528-80467788B27E@me.com> References: <1504526771666-0.post@n2.nabble.com> <2CB71C2C-D109-475E-B528-80467788B27E@me.com> Message-ID: <467567548.25493198.1504542410040.JavaMail.zimbra@comcast.net> From kd1na363 at gmail.com Mon Sep 4 12:27:41 2017 From: kd1na363 at gmail.com (David Robertson) Date: Mon, 4 Sep 2017 12:27:41 -0400 Subject: [Elecraft] Items you think you can depend on Message-ID: Everyone, Over time we can grow complacent on many service items such as electrical power, water and other services over time.

The distortion in an output stage increases if it is poorly matched to its load. Bob is my neighbor and we're both serious contesters. When I moved here, he made sure that I knew that, and that I kept my tube amp well tuned. Solid state amps mostly don't have tunable output networks, so the antenna tuner must provide that match. 73, Jim K9YC From farrerfolks at yahoo.com Mon Sep 4 13:32:34 2017 From: farrerfolks at yahoo.com (Mel Farrer) Date: Mon, 4 Sep 2017 17:32:34 +0000 (UTC) Subject: [Elecraft] Items you think you can depend on In-Reply-To: References: Message-ID: <1677217451.2689362.1504546354491@mail.yahoo.com> Funny you posted this.

If I change bands with the K3 band rocker button, go to 20 and then back to 17, the center remains where it is. However, if I change bands with the computer, for instance with WSJT-X, to 20M then back to 17M, then the center gets set to 18.150 -- I can no longer see the bottom 32 KHz of the band until I adjust the center again.

There have been no shortage of issues with Virtual Serial Ports on Windows with their dependence upon interrupt and event timing. I took a different route, developing a shared serial port that ?outsources? serial port management to a Raspberry Pi. This avoids all of the issues in Windows, provides better performance due to caching, and presents less load on the K3 than from multiple individual devices. -larry (K8UT) -----Original Message----- From: Wes Stewart Sent: Monday, September 04, 2017 2:36 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] OT - WSJT-X & K3s I asked about this on the Yahoo WSJT-X group: >From one of the developers, "Hi Wes, we do not support serial port splitting products with WSJT-X, they are unreliable as there is no acceptable way to divide control of a single device without arbitration.

Won't WSJT work in VOX mode with no serial connection at all? Start with the minimum possible, then add things one at a time. 73 -- Lynn On 9/4/2017 12:01 PM, Barry wrote: > > ???

I don't do any port sharing, giving WSJT-X the port by itself, and log manually in DXKeeper. WSJT--X does its best to idiot-proof the setting of drive levels by shifting TX frequency and audio frequency in opposite directions so that harmonics are always out of the passband of the sideband filter. WSJT-X can be set to use it or not, to do it by setting the radio for split mode, or by simply shifting the VFO. If you're not an idiot, you can take reasonable care in setting levels for the audio between computer and rig and for audio gain in the rig. :) Easy to follow guidelines are in the last page or so of http://k9yc.com/USB_Interfaces.pdf 73, Jim K9YC From w2ljqrp at gmail.com Mon Sep 4 16:11:46 2017 From: w2ljqrp at gmail.com (Larry W2LJ) Date: Mon, 04 Sep 2017 16:11:46 -0400 Subject: [Elecraft] 2017 NJQRP Skeeter Hunt -Results are in!

On the other hand having a well designed "arbitrator" works wonders. The only way that "serial port splitting" products work properly supporting all possible commands is with "virtual radios" as in Win4K3. Nonetheless, the issue here is not necessarily related. The first step is to get it working without any software in the way. If this can not be achieved then there are fundamental issues that need to be corrected first. Here are one set of settings: Rig: Elecraft K3/ KX3 Serial port: Connected to your radio. Baud rate, the same on both radio and WSJT-X Handshake: None Force control lines - all off PTT method, VOX or CAT Mode: Data/PKT Split: Rig These are the settings needed to start. If it doesn't work like this, start looking at the hub or the serial connection. If you run everything off a hub including a SDR and sound card or SDRPlay then this is probably the reason. Some computers just can't handle this. Now this being said, WSJT-X has a few issues when it uses CAT control. For example, it will change mode before it changes band. It will go in split before it changes band. The consequence is you have to do it twice at times. Hope this helps. 73 Tom va2fsq.com -----Original Message----- From: Wes Stewart Sent: Monday, September 4, 2017 2:36 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] OT - WSJT-X & K3s I asked about this on the Yahoo WSJT-X group: >From one of the developers, "Hi Wes, we do not support serial port splitting products with WSJT-X, they are unreliable as there is no acceptable way to divide control of a single device without arbitration.

I caught myself several times referring to the line voltage required as 220 even though I know better. My age is showing. But I do know that if one is operating the KPA1500 in a commercial building with 3 phase service, the voltage is 120/208.

Not always.? In much of the US, power is distributed as "high-leg Delta" (sometimes called "wild leg).? Three-phase customers get 240V Delta, single phase customers get 120-240 from a center-tapped transformer fed by one of the sides of the Delta. Neutral is established by the center tap. This configuration is widely used in cities, and is what serves me in the Santa Cruz Mountains. > The KPA1500 power supply is a switcher, and most switchers can > tolerate a wide variation in input AC voltage. And the KPA500 power transformer can be tapped for a fairly wide range of supply voltages. 73, Jim K9YC From k3ndm at comcast.net Mon Sep 4 19:11:10 2017 From: k3ndm at comcast.net (Barry) Date: Mon, 04 Sep 2017 23:11:10 +0000 Subject: [Elecraft] OT - WSJT-X & K3s In-Reply-To: References: <3110E1C232AF4089A0067C71BCF94F9F@lpbstar> <0cb84277-baca-dc22-ea71-85d00ed667c4@triconet.org> <7e04f0e8-7355-3bbd-a207-cf42489fd9ed@blomand.net> Message-ID: Lyn, I guess I can understand the developers position.

The Signalink uses an internal vox to know what to do and an acceptable sound card that will take the radio's audio and feed it to your digital software. You can plug a powered speaker into the Signalink's aux out and that will allow you to change modes without need to do anything that remove the mic and replace it with Signalink's mike cable.

And, the usual connection is serial port, even when that port is created by a USB connection. I have a hard time understanding why there is so much angst over serial ports. Windows has a window call device manger. In it, you can see what ports are being defined. If you use a USB connection, you can watch the port announce itself. Just for clarification, I AM NOT a computer scientist and need my spell checker to get it spelled correctly. However, I did learn about device manager and have been happy ever since. If you plan on having your logging software know where you are and band you're on and track other activities, you really don't get much choice; you must be able to share the data to/from the radio. The best thing, best behaved, is Win4K3 for the Elecraft users, regardless of whether you are a KX3 or K3 user. I am being told the KX2 is also fine and my K3s works great. The one thing I have found here and 1 other station is having forgotten which ports I was using for what; I now have that written down and life is sweet. 73, Barry K3NDM ------ Original Message ------ From: "Lynn W.

That has not been my experience. My antenna presents a real challenge on some bands, but right now, for example, on 14.019 I have 1.34:1 indicated SWR in the shack at about 20 watts tune power. Key down with the KPA500 in line, showing power of 585 watts and the SWR holding steady at 1.34:1. If I put my remote tuner in ByPass, and use my KAT500, I am seeing the SWR at 1.28:1, whether at 20 watts, or at 500 watts. But, I will gladly use the remote tuner which is right at the base of my 30' Flag Pole Vertical. It is not a big deal on some bands, but with 125' of LMR400 coax, there is more loss on a few bands than I want to give away. I cannot tune this antenna on 160 with the KAT500, because impedance is WAY too low, and the native SWR is 'out of sight'. The KAT500 is an awesome tuner, but nowhere near up to that task. My remote tuner will make the rig happy on 160, but my antenna is so short for 160 that many folks think I am crazy to even try it, but I never claimed to not be crazy... I just keep on having fun.

The SignaLink is a single channel soundcard, and its sound quality is "just OK" for digital modes. Yes, there are connecting cables for several transceivers available from SignaLink that make connection to the transceiver easy and straightforward - but those are the only advantages. There are external soundcards that will do a much better job for a lot less money. Especially if you are planning to use the RX I/Q outputs on the KX3 or the outputs of LP-Pan for the K3/K3S for a panadapter display. A good panadapter display wants to use a soundcard with a 192kHz rating and typically 24 bits. You must have a stereo soundcard for the panadapter function, and the SignaLink has only the left channel present. As for the SignaLink VOX, it is generated in the SignaLink from the audio stream. The KX3, K3/K3S VOX will work just as well as the "PTT" from the SignaLink. Due to the single channel implementation in the SignaLink, it cannot be used for panadapter applications. So if you want a soundcard that can be used for both soundcard data modes and a panadapter display, get a good external soundcard (look for 192kHz/24 bits). It will likely have a lower noise floor than the SignaLink as well. Soundcards that have been tested for Panadapter use are listed on the www.telepostinc.com website. There are some there that are 96kHz/24 bit which will not allow the full 192kHz width of the panadapter applications, but that is usable if you only want to display up to 96kHz of the band. Of course, it you want a superior panadapter display, consider the P3 (for the K3/K3S) or the PX3 for the KX3. 73, Don W3FPR On 9/4/2017 7:11 PM, Barry wrote: Use a Signalink USB to connect to your KX3 for > digital modes.

I may not have been sufficiently clear. You do need a good stereo card for the spectrum display and another card, typically, for digital modes. I use and usually recommend the Signalink USB for use with digital modes for 2 reasons, they are inexpensive and they can key your transmitter directly. There has been a lot of discussion on what card to use for the spectrum display and a good source of data on cards is available on the LP-Pan site. I won't get into what I do and card I use as I don't want to start another branch in this discussion. Having said that, I am using a good professional level card for spectrum and CW Skimmer. 73, Barry K3NDM ------ Original Message ------ From: "Don Wilhelm" To: "Barry" ; "Lynn W.

For example, some "12 V" things that I use are external disk drives, powered USB hubs, radio accessories, and computer peripherals of all sorts. Some manuals list this, sometimes we are lucky just to get an instruction sheet with pictures let alone text. So far I've been satisfied with my power board set for a "regulated" level of 14.1 V for transceivers and "float" level (nominally 13.8 V) for everything else -- but I was wondering.

Is it really the same electrons that flow from the municipal generator to our rigs and then back to the powerhouse again? I would have guessed that any individual electron motivated by an applied voltage would simply have moved an atomic diameter or two to fill in a spot in an adjacent depleted valence shell, such that a current flow is actually a shuffling of electrons from one positive ion to the next, but that individual electrons really don?t move very far. And then they all shuffle back the other way every one sixtieth of a second. Sort of like cars on Route 128 around Boston, as I recall from my days there. On the other hand, maybe the uncertainties in the quantum wave function preclude our ever knowing an electron?s position anyway, in which case the question is moot, right? For those who care to respond, be kind. I am a lawyer, not a physicist. I will return the graciousness if anyone has a question about the mediaeval origins of the writ of coram nobis.

As a KX3/PX3/KXPA100 owner, with over 1,000 JT65/JT9/FT8 QSOs in my log, I can honestly say the only things you need to run WSJT-X on your KX3 are these: 1.? Good Soundcard with a 48kHz DVD quality input/output.? I use a Sound Blaster SBx pro USB soundcard picked up from Amazon.? There are cheaper USB sound cards available, but I went with a known producer of quality sound cards.? I've been using Sound Blaster cards since the 1990's. 2.? The KXUSB cable.? This is used for CAT control from the KX3 to the PC. 3.? Two stereo cables for audio input & output. I use the cables that came in the KX3-PCKT cable kit.?? Work like a charm That's all I need externally.? However, I would definitely run the ** KX3 VFO TEMPERATURE COMPENSATION, if you have not done it. ? You will need a good signal source.? I just picked up the XG50 kit from Elecraft. As far as WSJT-X settings: Radio tab: Rig: Elecraft K3/KX3 Serial Port:? you need to check to see what windows lists as the COM port, should be the same as used by the KX3 Utility Baud Rate:? same as the Utility, 38400 Data Bits:? Eight????? Stop Bit:? 2? (never touched these,probably the WSJT-X default) Handshake:? None No need to mess with the Force Control Lines. PTT Method:? CAT Transmit Audio Source (Should be grayed out) Mode:? Data/PKT Split:? Rig (its what I use as I have the KXLF3 filter installed Click the Test CAT button, it should turn green.? Click the Test PTT, it should turn RED.? Click it again to turn off. On the AUDIO Tab, you need to select the soundcard you're going to use.?? Its always a good idea NOT to use the internal card, as you have system sounds going through that too.?? Which is why an external soundcard of some type is recommended. Input:? Line IN on the SBx soundcard (Speaker input on KX3) Output:? Speaker on the SBx soundcard (Mic input on KX3) Finally, you must make sure you have a good time SYNC program install on your PC.??? Your time must be sync'd to within 1 sec as FT8 is much more demanding on time sync than other digital modes.

That's what I use now since, since I upgraded my K3 to have the internal sound card. When I was using a SignaLink, i actually built a cable for the PTT. The reason is that the K3 does not save VOX by mode and I was always getting VOX on when I switched to voice modes. I have too many conversations with others in my shack to be able to use VOX. Now I'm back to having to remember to switch VOX on and off as I change modes. When I forget I either don't transmit on my first digital transmission, or I do transmit when I talk near the microphone. I'm a really slow learner. 73 Bill AE6JV On 9/4/17 at 4:55 PM, donwilh at embarqmail.com (Don Wilhelm) wrote: >As for the SignaLink VOX, it is generated in the SignaLink from >the audio stream.

The only good reason I can think of for using the SignaLink is if that's all you have and you can't afford to replace it. It is NOT a good audio interface. More times than I can count, I've posted a link to my recommendations for much better audio interfaces that are MUCH cheaper, AND they're stereo. That means, for example, that with two VFOs or two receivers, you can have two instances of WSJT-X running either copying different frequencies or doing diversity reception! In addition to WSJT modes, I use my stereo sound card to do SO2R SSB and RTTY contesting. http://k9yc.com/USB_Interfaces.pdf And as Don has noted, the SignaLink derives PTT from the audio stream by a process known as VOX.? :) Your rig can do that as well. 73, Jim K9YC From donwilh at embarqmail.com Mon Sep 4 23:12:03 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 4 Sep 2017 23:12:03 -0400 Subject: [Elecraft] OT - WSJT-X & K3s In-Reply-To: <98d1597c-0e4b-fc0e-a3cf-5ab9f809a739@techie.com> References: <3110E1C232AF4089A0067C71BCF94F9F@lpbstar> <0cb84277-baca-dc22-ea71-85d00ed667c4@triconet.org> <7e04f0e8-7355-3bbd-a207-cf42489fd9ed@blomand.net> <98d1597c-0e4b-fc0e-a3cf-5ab9f809a739@techie.com> Message-ID: <6ca23bd9-201a-0da7-b62a-dd0d43f6739a@embarqmail.com> All good information, although you may want to check which is your Default soundcard.

I have no problem starting simple and seeing if it works. I have been in a position of needing to find what was happening without knowing what all was actually going on, something akin to solving for 2 unknowns with only one equation. However, I think you really need to know where you are going and establish a framework for that. I'm not convinced starting with just a single mode generator/decoder is the way to go. You are going to need to do at least some logging ability. Here you are, two requirements and no framework. I know I've been doing this for a long time, and I kinda knew where I was trying to go. So, I built my framework first, and then started to hang other applications on it. It appears to me we view things from different perspectives. Do I think you are wrong? NO, I don't.

The answer is that all the free electrons in the conductor move. Since there's a lot of free electrons in the cross section of a piece of wire, they're not moving very fast. OTOH, 1 amp of current is 6x10^18 electrons flowing past a given point per second, which is an awful lot of electrons. So, they are moving much farther than some atomic diameters, but if they want to visit the power company, they're going to be disappointed. It's called "drift velocity". 73, Josh W6XU On 9/4/2017 7:09 PM, Dauer, Edward wrote: > Is it really the same electrons that flow from the municipal generator to our rigs and then back to the powerhouse again? I would have guessed that any individual electron motivated by an applied voltage would simply have moved an atomic diameter or two to fill in a spot in an adjacent depleted valence shell, such that a current flow is actually a shuffling of electrons from one positive ion to the next, but that individual electrons really don?t move very far. And then they all shuffle back the other way every one sixtieth of a second.

But when you change either of those with the knobs, the change will be remembered. I use macros sent from DXLabs Commander program to set and reset a "pileup mode" in which the dx station is moved near the left edge of the screen and the span is reduced. If I go to another band the P3 will go back to 'normal' state. If I know I am going to be doing this I will manually change the parameters slightly back and forth in order to force them to be saved. Since I can easily send the macro to enter the special mode or reset everything to normal, this hasn't been a problem for me. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 4 Sep 2017 23:29, Fred Jensen wrote: > It annoys me too.?

I'm dropping the one to which I am not subscribed. There are two classes of "12V" equipment: * equipment designed for lead acid batteries, of which amateur radio equipment is typical; * computer equipment. The former is actually designed for 13.8V with a wide tolerance, although mainly downwards. The latter is designed for 12.0V with a tolerance of maybe 5%, and expectations of rather better. Depending on what it contains, it may actually tolerate a rather wider range. -- David Woolley K2 06123 On 05/09/17 01:09, Phil Kane wrote: > That is true for Elecraft equipment but I was referring to "generic" 12V > stuff.

The attenuation needed to reduce 1 V to 50 mV is 46 dB (20log(.005/1)). Transceivers using electret mics (e.g., Icom), have a typical mic input around 0.05 V RMS which implies the need for a 26 dB attenuator. Note, the mic preamp stage of transceivers designed for an electret mic typically has lower gain (~20 dB less) than those with dynamic mics are are thus far less likely to be driven into clipping. 73, ...

Instead, I have the SignaLink USB along with the Elecraft KX3 personality module and interface cable, and once I got over my initial hesitation to use it (a hesitation borne of the comments of "everybody says it's an inferior sound card"; because of that, I was loath to put it in service) I find that it is a satisfactory solution; it doesn't have nearly the fiddle factor and instabilities that I faced with the other interfaces and it satisfies my needs admirably. So I guess the one phrase I can use is "Different strokes and all that" when it comes to interfaces. :) --- 72, Rich Hurd / WC3T / DMR: 3142737 PA Army MARS, Northampton County RACES, EPA-ARRL Public Information Officer for Scouting Latitude: 40.761621 Longitude: -75.288988 (40?45.68' N 75?17.33' W) Grid: *FN20is* On Mon, Sep 4, 2017 at 10:24 PM, Walter Underwood wrote: > I cannot agree with the Signalink USB being inexpensive.

The > attenuation needed to reduce 1 V to 50 mV is 46 dB (20log(.005/1)). Joe, While I greatly respect your engineering, the output of a dynamic mic varies widely depending on what it's hearing. The classic "little old lady on a lavalier" in a TV studio may produce only 5-10mV, but when worked close to the mouth, as most ham mics should be used, the output is more like 100 mV. The fictional lead vocalist Arthur Leatherlungs can easily drive a dynamic mic to 1 V. Not only that, many ham mics are electrets, which tend to have output levels equal to or greater than dynamic mics. The mic input stage must accommodate all of these mics. Although I've not measured input clip levels of ham gear, I'd be quite surprised if they clipped below about 100 mV. And clip level is what matters. As to computer output levels -- while RATED output level for clip is typically in the range of 1V RMS, some I've measured suffer from increasing distortion 6 dB below their actual clip level. I've measured -30 dB harmonics just below clip, and -40dB at 6 dB below maximum output. Further, while pro systems are correctly adjusted so that all stages in a signal chain clip at the same level to maximize signal to noise, those systems are going for 100 dB or better. Few ham systems need better than 50 dB SNR in the audio spectrum, but distortion products can be critical. SO -- the output of a computer audio interface should not be run at its maximum level, certainly not hotter than about 0.5V RMS. Years ago, the venerable Shure M67 and M68 were designed so that they clipped in the range of 50 mV, and Shure had to sell inline pads (10-15 dB attenuators) to prevent overload. A new company, Tapco, led by Greg Mackie developed new inexpensive small mixers to compete with Shure, and ended up eating Shure's lunch with an input circuit with feedback control of input gain that handled much higher signals without overload. For at least 40 years, any pro mic input will handle signals up to at least 3V RMS through the combined use of switchable pads and feedback gain control. 73, Jim K9YC From jim at audiosystemsgroup.com Tue Sep 5 13:19:31 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 5 Sep 2017 10:19:31 -0700 Subject: [Elecraft] OT - WSJT-X & K3s In-Reply-To: <014525a7-1483-1612-7e85-a1283d2a55e3@techie.com> References: <45bba0fb-93ef-b631-710a-6b9cab3eda8a@embarqmail.com> <38b11fc7-98d0-fd87-0a25-fdbe4d3ce92c@triconet.org> <014525a7-1483-1612-7e85-a1283d2a55e3@techie.com> Message-ID: <1dffeb4e-11f7-c28a-b127-b8d9af6e3f38@audiosystemsgroup.com> On 9/5/2017 9:32 AM, Neil Zampella wrote: > The only problem with VOX and the soundcard is if you have only one > soundcard, and you also have Windows sounds going to it.

Used the serial output as a datalogger to track the grid dips (as low as 90v on 115v mains). This was in the mid-90s; I'd expect there to be a number of other solutions today.

Dig out the service manuals and run their mic circuits through SPICE or one of the other software programs that will show you where they clip. You will find almost without fail, the common emitter transistor preamp with unbypassed emitter bias resistor is, in fact, clipping well below 1V. Those preamps invariably have between 26 and 30 dB of gain and the outputs are connected in parallel (with or without switching) with the "Line In" (old Patch jack which was typically rated for 100 - 500 mV) which then drove the audio stage which included the mic gain control. Remember, we're talking about *AMATEUR* equipment - not professional and broadcast equipment with its 1V or 4V P-P standard "Line" levels and wide range mic preamps that provided standard level outputs Some newer rigs do better - high impedance, low noise op amp preamps that are much less sensitive to overload. TenTec had a "line" input with a 4V P-P tolerance but those "features" are far from the norm, particularly considering the number of 25 and 30 year old rigs still on the air. In any case, a typical dynamic microphone - professional or amateur - is rated around -55 dBV/Pascal (check Shure, EV, etc.) some may be a more sensitive, some less. For those who do not know, 1 Pascal is a 94 dB Sound Pressure Level (think traffic on a busy roadway) - nearly 25 dB above the EPA threshold for hearing protection! -55dBV is in *the millivolt range*. 5 mV is a decent level for normal conversation with a dynamic microphone within 6" of the lips. All of this information is available from public sources and a little study. 73, ...

The classic "little old lady on a lavalier" in a TV studio may produce only 5-10mV, but when worked close to the mouth, as most ham mics should be used, the output is more like 100 mV. The fictional lead vocalist Arthur Leatherlungs can easily drive a dynamic mic to 1 V. Not only that, many ham mics are electrets, which tend to have output levels equal to or greater than dynamic mics. The mic input stage must accommodate all of these mics. Although I've not measured input clip levels of ham gear, I'd be quite surprised if they clipped below about 100 mV. And clip level is what matters. >> As to computer output levels -- while RATED output level for clip is typically in the range of 1V RMS, some I've measured suffer from increasing distortion 6 dB below their actual clip level. I've measured -30 dB harmonics just below clip, and -40dB at 6 dB below maximum output. Further, while pro systems are correctly adjusted so that all stages in a signal chain clip at the same level to maximize signal to noise, those systems are going for 100 dB or better. Few ham systems need better than 50 dB SNR in the audio spectrum, but distortion products can be critical. SO -- the output of a computer audio interface should not be run at its maximum level, certainly not hotter than about 0.5V RMS. >> Years ago, the venerable Shure M67 and M68 were designed so that they clipped in the range of 50 mV, and Shure had to sell inline pads (10-15 dB attenuators) to prevent overload. A new company, Tapco, led by Greg Mackie developed new inexpensive small mixers to compete with Shure, and ended up eating Shure's lunch with an input circuit with feedback control of input gain that handled much higher signals without overload. For at least 40 years, any pro mic input will handle signals up to at least 3V RMS through the combined use of switchable pads and feedback gain control. >> 73, Jim K9YC >> ______________________________________________________________ >> 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 >> Message delivered to lists at subich.com > ______________________________________________________________ > 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 > Message delivered to wunder at wunderwood.org From Gary at ka1j.com Tue Sep 5 17:21:52 2017 From: Gary at ka1j.com (Gary Smith) Date: Tue, 05 Sep 2017 17:21:52 -0400 Subject: [Elecraft] OT - WSJT-X & K3s Message-ID: <59AF1570.15734.91C3038@Gary.ka1j.com> The topic has recently drifted a bit from my original question but the information given has been interesting.

That includes WSJT. When using the internal soundcard, make certain there is nothing connected to the LINE IN jack - it takes precedence over the output of the internal soundcard. As always, set the audio level to show 4 bars solid on the ALC meter with the 5th bar flashing (the WSJT instructions are not correct for the K3/K3S). Adjust the power level with the POWER knob. 73, Don W3FPR On 9/5/2017 5:21 PM, Gary Smith wrote: > The topic has recently drifted a bit from > my original question but the information > given has been interesting.

I suggest that you drag out a scope and look at the output of some these mics with speech with different people and different working distances. The variables are distance and how loud the speech is. I know guys who get pretty excited calling DX or during a contest. And sound pressure level follows inverse square law, just like antennas. That means the voltage doubles (+6dB) every time the distance between mic and mouth drops by a factor of 2.? 1-in to 2-in is 6 dB. 2-in to 4-in is 6 dB. 4-in to 8-in is 6 dB.

Tap RX ANT to listen to the RX ANT on MAIN. If you have the Sub RX (KRX3), you can connect the RX antenna to the BNC labeled AUX. Enable the SubRx (tap SUB), then HOLD the RX ANT button to toggle the SUB RX ANT between MAIN and AUX. There is no way to listen to the AUX BNC connector on the MAIN receiver, only the Sub RX. I assumes you have CONFIG:KRX3 set to ANT=BNC. If you have CONFIG:KRX3 set to ANT=ATU *and* you have wired the radio that way (there are two antenna wiring options for the SubRx), then the SubRx can listen on ANT1 or ANT2, whichever is not being used by the MAIN, instead of AUX. It seems there was a decision to make when I assembled it that had to do > with antenna configuration and I cannot find it in the manual. This is best explained in the KRX3 Installation on Operation manual , page 26. If you have two transmit antennas, say an all band vertical and a multi-band dipole, the ANT=ATU wiring option allows you to transmit on whichever one is hearing best on any particular signal, or you can use diversity reception and listen on both, one in each ear. 73, Bob, N6TV From n6tv at arrl.net Wed Sep 6 02:51:02 2017 From: n6tv at arrl.net (Bob Wilson, N6TV) Date: Tue, 5 Sep 2017 23:51:02 -0700 Subject: [Elecraft] K3(S) QSK Operation In-Reply-To: <1459baad-f9fd-8c0b-ec10-a8bb98ecc6de@sdellington.us> References: <1459baad-f9fd-8c0b-ec10-a8bb98ecc6de@sdellington.us> Message-ID: The 37 WPM jitter issue is actually related to VOX timing (with either QSK or semi-breakin). If you hold the PTT line closed while transmitting, via a foot switch, software-controlled PTT, or an external keyer like a WinKey with a PTT output, you can send as fast as you like, no CW jitter, but you give up QSK and semi-breakin. This works whether you have VOX ON or OFF. For more details, see this post from about 4 years ago: http://lists.f5mzn.org/pipermail/support/2013-November/083384.html The new KSYN3A synthesizer is highly recommended though, especially for QRQ CW.

Do that test first. You should see the RX ANT icon in the display. Then with the RX ANT still selected, move the antenna to the jack labeled RX ANT IN (not RX ANT OUT) and you should once again hear the signal at full strength. If not you have a problem with the KXV3 and should contact support. If you have the SUB RX, the situation becomes more complex, so do not select SUB when trying this testing.

Tap RX ANT to listen to the RX ANT on MAIN. If you have the Sub RX (KRX3), you can connect the RX antenna to the BNC labeled AUX. Enable the SubRx (tap SUB), then HOLD the RX ANT button to toggle the SUB RX ANT between MAIN and AUX. There is no way to listen to the AUX BNC connector on the MAIN receiver, only the Sub RX. I assumes you have CONFIG:KRX3 set to ANT=BNC. If you have CONFIG:KRX3 set to ANT=ATU *and* you have wired the radio that way (there are two antenna wiring options for the SubRx), then the SubRx can listen on ANT1 or ANT2, whichever is not being used by the MAIN, instead of AUX. It seems there was a decision to make when I assembled it that had to do > with antenna configuration and I cannot find it in the manual. This is best explained in the KRX3 Installation on Operation manual , page 26. If you have two transmit antennas, say an all band vertical and a multi-band dipole, the ANT=ATU wiring option allows you to transmit on whichever one is hearing best on any particular signal, or you can use diversity reception and listen on both, one in each ear. 73, Bob, N6TV ______________________________________________________________ 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 Message delivered to markmusick at sbcglobal.net From markmusick at sbcglobal.net Wed Sep 6 09:02:46 2017 From: markmusick at sbcglobal.net (Mark E.

Also, see KSYN3A FAQ on the Elecraft website order page. 7. How does the new synth affect CW operation? a. The KSYN3A switches faster than the KSYN3, which allows us to more precisely control CW timing. This means less "jitter" (timing variation) at high CW speeds. Many CW operators who had been using "QRQ" mode (CONFIG:CW QRQ=ON) for CW in the 35-60 WPM range will now be able to use normal CW mode (CW QRQ=OFF), meaning they no longer give up RIT and SPLIT when using fast CW. Receive recover times also improve. Note that we recently introduced a variation on CW break-in signal processing called "NEW QSK" (selected by tapping '3' in the CW WGHT menu entry). This eliminates audio T/R artifacts heard with the original algorithm ("OLD QSK"), at the expense of some slowing of receive recovery (by purging the DSP's "pipeline"). Installing a KSYN3A speeds up receive recovery for both the OLD and NEW QSK settings. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of K9MA Sent: Wednesday, September 6, 2017 2:25 PM To: Bob Wilson, N6TV ; Elecraft Reflector Subject: Re: [Elecraft] K3(S) QSK Operation Thanks, Bob.

That said, I agree with K9MA's post that "I have never found the K3 noise blanker to be effective". Though I would probably modify the word "never" to " very seldom". I realize that a great deal of work has gone into making the K3 NB all it can be but it needs improvement. I've found the NB on other radios to work a a great deal better reducing both impulse and even the "Electronic generated noise" mentioned by K9YC. There has to be a way to improve the K3 NB and I sincerely hope that more work will be done on this needed improvement. 73, Dick- K9OM On 9/3/2017 9:18 AM, K9MA wrote: > I have never found the K3 noise blanker to be effective. > BTW, the K3 noise blanker uses a filter with a bandwidth of about 100 kHz. The K3 NB is really TWO blankers, operating in two different IFs. Each can be tweaked for various kinds of noise from the menu system.? Access the menu by a Long Push of the NB button. It's important to understand that there are many kinds of noise. Noise blankers are most effective on IMPULSE NOISE, which is the result of something arcing, usually in the power system, but also electric fences and neon signs. Most of the residential noise we hear today is ELECTRONIC noise, generated by switch-mode power supplies and microprocessors.? Noise blankers must be very different to suppress this sort of noise. The menu tweaks provided by the K3, K3S, KX3, and KX2 are very critical to making the NB effective on the noise you're experiencing. One size does NOT fit all. 73, Jim K9YC From dave at nk7z.net Wed Sep 6 14:23:29 2017 From: dave at nk7z.net (Dave Cole) Date: Wed, 6 Sep 2017 11:23:29 -0700 Subject: [Elecraft] Radio storage cases In-Reply-To: <01e801d32736$9421d9c0$bc658d40$@cox.net> References: <01e801d32736$9421d9c0$bc658d40$@cox.net> Message-ID: Depending on the radio, a garbage can might work! :) Sorry, I had too... 73s and thanks, Dave NK7Z http://www.nk7z.net On 09/06/2017 10:35 AM, Erik Basilier wrote: > I have always used temporary solutions for storage of my smaller radios, > such as the KX3 and KX1.

A quick look suggests that amplitude is down significantly in the vhf range, so given the size of an ammo can, it would probably be ok even if the lid is connected at only one point. However, it seems that there is significant spectral content up into the GHz range, and I would feel safer with contact all around the edge. Anyway, an ammo can is rather heavy. It would be nice to be able to bring the shielding container along on a camping trip without re-packing in a lighter container. If one accepts the need to re-pack, one might as well use a bigger container such as a full size trash can, and use it to shield a variety of electronic devices. In my mind I see some kind of camping food container made of aluminum that was used in my childhood. I guess that product has been displaced by plastic containers long ago. OTOH there are now companies that specialize in selling mesh or conductive fabric for turning your whole bedroom into a Faraday cage. Could there be a market for custom radio cases that incorporate a layer of such shielding material? 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Clay Autery Sent: Wednesday, September 06, 2017 11:42 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Radio storage cases Yes, all true milspec cans have gaskets for water-tight fit...?

Probably not worth the effort (removing that paint is difficult). The simple ground strap between top and bottom seems to work. A ?test, if you have full bars on your CDMA phone, is to place the mobile in the box and send yourself a text message! A CDMA phone is preferable to GSM because of its ability to add multi-path into a stronger signal. (This test may not be conclusive depending upon how fast the risetime of an EMP actually is. Should be OK for slower CME).?For those legacy radios in storage, a simpler solution might be to wrap them in a couple layers of aluminum foil! A more complicated solution is to build a house like mine: passive solar, 10 inch concrete walls & ceiling, 4 feet underground.

The ONLY way the engine speed can vary is to utilize an SS circuit to generate the required 60 HZ sine wave. I currently have a Honda EU7000 set up in an "almost" automatic running mode. I have to manually start the generator and hit a push-button which energizes a big transfer switch so certain circuits in the house go from mains to generator. When commercial power is restored for at least a continuous minute, the system reverts back to mains power. I then have to manually shut off the generator. Glad to see Generac moving to this type. It should make your UPS systems much happier. 73, Charlie k3ICH'' -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Mark Bayern Sent: Thursday, September 07, 2017 5:16 PM To: Mel Farrer Cc: Elecraft List ; Doug Hensley Subject: Re: [Elecraft] OT: Whole House Generator I found that Generac has a series of egens they call the 'Synergy' line.

We also had a Honda inverter [2 KW], used primarily in econo-mode to run the electric blankets at night [very quiet idle].? It was RF-quiet too, just struggled some if we tried to run the station on it. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/7/2017 1:54 PM, Mel Farrer via Elecraft wrote: > I tried to get more information on the "syntergy" process. ?I know of no electrical design of the alternator that allow a non distorted change in frequency of the output, ?However a method of load sensing and a planetary transmission with speed selection could do the job of letting the motor run slower while the alternator is at constant speed. ?The 5-12 minute load sensing could be the process of the speed selection so that no load is affected. ?Hummm interesting. > I have a 35 KW diesel Generac and never looked back. ?It uses the old governor method of adjusting engineer fuel/RPM to load.

Key questions are" 1) What loads do I need to run from it? Get hard numbers, including starting current for motors (refrigerators, well pumps, etc.) The 120V loads can easily be measured with a Kill-A-Watt meter. You'll need a clamp-on current probe for your VOM or scope to measure permanently wired loads and 240V loads. 2) How often are power outages?? How long do they last? 3) Do I really need to run A/C from a generator?? Obviously depends on climate, but also demands a bigger generator and a lot more fuel. I have two generators. One is a Honda 2000i, which I can easily carry, and use for portable hamming. The second is a 6.5kVA Honda (EU6500?) that can be set for either 120VAC or 120/240 with a neutral. I use it in the 120/240V mode. It's big enough to run my well motors. I've rewired the breaker panel in my home to put all my "critical" loads on one side of 120V -- lights, computers, TV, refrigerator -- and have found that the little 2000i can run it all in econ-mode. That gives us the option of using the smaller generator until we need to re-build the water pressure during a long outage. 73, Jim K9YC From n6kr at elecraft.com Thu Sep 7 20:49:13 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Thu, 7 Sep 2017 17:49:13 -0700 Subject: [Elecraft] 6 meter auroral propagation opening Message-ID: Just worked K7CW via auroral reflection on 50.136 CW.

Message-ID: <8c27486d-6bcc-990a-21a8-22f36920c4d4@montac.com> I need help shortcutting the response time to solving my problem. I am in the CW Academy trying to learn code, and don't have time to futz around trying to fix this issue and don't have money to throw at the problem right now. ISSUE:? Cannot seem to figure out how to get the CW Monitor (what I am sending) to mix with my voice audio via mic (either of them) and OUT via Skype for practice or class sessions. Current: Right now, I am simply setting SPKR+PH to "Yes" and turning the monitor level up to 60 (max) in order for my microphone to pick it up.? This is LESS THAN ACCEPTABLE as a solution as the K3 is on a shelf above the microphones and the mics don't pick up the audio well... How I am currently set up: Laptop: Dell Latitude E6540 on docking station. Radio: K3s connected to Laptop via USB cable Webcam: Logitech C922 connected to Laptop via USB Boom Microphone: ?- Connected to K3s via Mackie Onyx Blackjack 2x2 USB Recording Device (this is where the mic gets phantom power), Mic into Onyx via Mic channel and out via Right Monitor Out to the REAR K3s Mic IN jack. ?- Connected to Laptop via the Mackie Onyx USB connection to the laptop (this USB connection provides POWER to the Onyx and signal from the Onyx mixer to the laptop for recording ?- THUS, I can use EITHER the mic from the webcam OR the "Radio Microphone" for Skype...? I use the latter as I can use the same mic for Radio ops AND Skype at the same time (PTT for radio w/ mic muted in Skype). One would think I could figure out a way to mix the keyer audio stream over the USB connection AND the mic audio stream form USB connection IN the laptop via the soundcard and put the mixed audio out over Skype...? So far unsuccessful in this regard.? I can feed the signal from the radio to Skype OR the microphone...? Can't mix them... or at least can't figure out how to do it successfully. __________________________________________________________________________ So, I've decided to try to pull the signal off the radio via one of the outputs on the rear of the K3s....? (Speakers, Phones, or Line Out).? I would prefer NOT to use the Phones output as I use my headphones all the time and don't want to mess with switching plugs all the time (not easily accessible).? I CAN use the Speaker Out port, but I will be getting external speakers soon and would need to figure out a way to NOT have to switch stuff around there too eventually....? Line Out SEEMS to be the best candidate for now, although I seem to remember something about plugging into Line Out kills the USB audio line? or something. Whichever audio out signal I use, I plan to put it into the Onyx on its second channel...? the Onyx SHOULD take care of the mixing duties and I should be able to then grab the mixed signal for Skype via the laptop....? I hope. Anyway...? I will research this, but sure would appreciate it if one of you folks who've already crossed this bridge could help me shortcut the time suck for fixing this so I can use my time to practice instead of playing amateur audio engineer....? -- ______________________ Clay Autery, KY5G From kg9hfrank at gmail.com Thu Sep 7 22:56:07 2017 From: kg9hfrank at gmail.com (kg9hfrank at gmail.com) Date: Thu, 7 Sep 2017 21:56:07 -0500 Subject: [Elecraft] 6 meter auroral propagation opening In-Reply-To: <435741877.2267290.1504834032320.JavaMail.root@starpower.net> References: <435741877.2267290.1504834032320.JavaMail.root@starpower.net> Message-ID: Heard it on 14.3MHz signals in Northern Illinois, during the Net about 6pm local.

Are you driving the audio to illuminate 4 bars on the K3S ALC meter with the 5th bar flashing? You must operate Elecraft gear differently than other transceivers because of the closed loop system used for power control is different than the simplistic "control the drive level" system that other transceivers use.

However, the addition of suitable tanks and piping, which MUST be installed "professionally", would be well over the cost of the generator itself. All of you with non-invertor conventional 3600 RPM generators should take a look at the actual waveform coming out of them. My older Honda ES-6500 would run anything I connected to it, but my computer UPS did NOT like it. The waveform was basically 60 Hz but there was noticeable distortion and glitches. The inverters are certainly more complicated with potentially more things to fail, BUT the waveform out of My Honda EU-7000 is audio signal generator clean. 73, Charlie k3ICH On 9/8/2017 8:46 AM, Chip Stratton wrote: > I have a Kohler 8 kw unit on a whole house automatic transfer switch > that runs on propane, No A/C so 8 kW supplies the whole house just > fine.

I have had no problems using the internal speaker on my KX2 operating in the field. Plenty of volume and clarity, even operating in some fairly brisk winds. My experience is strictly CW, but imagine SSB would be the same. With the internal battery pack, it is a totally self-contained rig (except antenna) in a single box you hold in your hand.

The K3S setup and operation does not follow the suggestions for setting the audio levels as other radios and as described in the WSJT-X user information. In DATA mode, it is my view that A L C stands for AUDIO? LEVEL CREST.? i.e. the highest point, level or degree. ? ? It does not, in my terms, stand for Automatic Level Control as understood by many and as used on many other radio brands.?? Although, in SSB mode, the the normal convention of understanding with ALC does apply. With regard to WSJT-X, there is provision, in the AUDIO tab to have the levels remembered by band? for Transmit and Tune.?? I find with these boxes checked things work quite well.? Just remember that the transmit data level can or will be different than the tune level.? Thus some minor adjustment of the PWR slider in the software may be needed between TUNE and TRANSMIT.? Once done, all other things remaining static, the power from band to band and day to day remain precise as one desires. In my measurements, in DATA A mode with a single tone applied, I find that any audio level where the A L C indication? {AUDIO LEVEL CREST}? is less than 4 bars will allow the power control circuit in the radio to "hunt".? The result will be observed as a slow power increase. I'm stubborn, hard-headed and have used many other brands and models of radios in the past.? As I've said before, I had to learn to use the K3S as it is intended, thus it is not like other radios in this respect.? Once done, you'll be much more satisfied with its outstanding performance. 73 Bob, K4TAX K3S s/n 10163 On 9/8/2017 7:36 AM, Don Wilhelm wrote: > Bret, > > This is a condition we call "Power Hunting", and it usually indicates > that you do not have the audio level set correctly for Elecraft > transceivers. > > Are you driving the audio to illuminate 4 bars on the K3S ALC meter > with the 5th bar flashing??

That is the point of "Zero ALC" for the K3/K3S/KX3/KX2. The K2 is different in its indication in that the ALC begins at the 1st bar illuminated. The data mode setup for the K2 is the same - set the audio level correctly and control the power with the power knob. So for the K2, you advance the audio until you begin the see the 1st ALC bar illuminated and then back off until it goes out. 73, Don W3FPR On 9/8/2017 2:41 PM, Bob McGraw K4TAX wrote: > Don is absolutely correct on his earlier points.??

I recently acquired two K3s, and this is my first post to this list. One of the K3s has the 2-meter module in it but I haven't had it on the bench to test it. Looking to get some real data on the 2-meter module. Background: I'm mainly an HF contester, but I've also been known to operate on the higher bands. In the upcoming second weekend of the ARRL 10-GHz-and-Up Contest, I'll be operating on a few hilltops in ENY and New England and I'd like to use the K3 with the KX144 as the IF radio for my 10-GHz transverter. So today I have two topics: 1) How far down can I dial the K3 RF output on 144 MHz? On a related note, does the RF output spike toward full output (6-7 W) on key-down when the RF output is dialed way down? 2) Can I disable the PA in the 2-meter module through a menu setting or some other way that doesn't involve modifying the radio? Looking to get down to the 20-mW level for IF drive. The transverter has a single IF connection with PIN diode T/R switching. If needed, I could separate the transmit IF input and the receive IF output, but it would be better if I can keep the current configuration. Thanks in advance. --73, Rus, K2UA From donwilh at embarqmail.com Fri Sep 8 15:50:19 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 8 Sep 2017 15:50:19 -0400 Subject: [Elecraft] [K3] USB Interface In-Reply-To: References: Message-ID: John, Look back to posts earlier today regarding WSJT-X. We have been discussing how to set the audio levels for WSJT-X, but the same thing applies to and all other soundcard digital modes, including AFSK A - which you should be using with MMTTY. It defaults to LSB, turns off compression and TX EQ (so you don't have to disturb your SSB settings). See the manual for the features available with AFSK A mode. Set the MIC SEL to LINE. Like all other data modes with the K3 (and other Elecraft gear), set the audio for 4 bars on the ALC meter with the 5th one flashing. Adjust the power with the POWER knob. Ignore the common internet advice (and some software instructions) which say to "set the power to maximum and use the audio level to control the power" - that does not work well with Elecraft gear because it is unique among amateur tranceiver in the way the power is controlled. Some commercial transceivers control power in the same way as Elecraft gear, but no other amateur transceivers that I am aware of. 73, Don W3FPR On 9/8/2017 3:02 PM, John Reilly wrote: > I have the USB interface card in my K3.

I have had no problems using the internal speaker on my KX2 operating in the field. Plenty of volume and clarity, even operating in some fairly brisk winds.

The K3S manual on page 30 says among other things: "While speaking into the microphone in a normal voice, adjust MIC for a peak ALC meter indication of about 5-7 bars (see below)". Then regarding audio data modes it says on page 34: "If you?re using an audio-shift transmit mode (LSB, USB, DATA A, or AFSK A), you?ll need to set the MIC level while watching the ALC meter. You can use the same procedure outlined for voice modes (pg. 30), except that speech compression should not be used." So 5 to 7 bars seem to be indicated.? Where does the '4 solid, fifth flashing come from'? This is particularly questionable with constant amplitude modes, where it doesn't matter whether there is ALC developed or not. Maybe someone can enlighten me. Wes?

As explained by Wayne and Lyle several years ago, in data modes the ALC meter scale is shifted so that any display below four bars shows *audio input level* below the nominal operating point (whatever point below the ALC clipping level Lyle set to allow headroom) while five bars or more represents ALC action. In data modes (DATA A, AFSK A), the DSP algorithm will *increase* the audio gain (effectively increase the mic/line in level) as needed to provide sufficient audio drive for the DSP to work correctly (generate the nominal signal level prior to the ALC/Power setting routine). 73, ...

Set it first for midrange (about 30), and then set the soundcard "speaker" output slider for about 50%, and set the WSJT-X slider also to about 50%. Then see what the ALC meter reads during a transmit. You should be able to do that in TX TEST mode, or working into a dummy load so there is no need to put those "testing" signals on the air. With the K3 LINE IN set to midrange, adjust the computer sliders so you get close to the 4 bars with 5th bar flashing. Then fine tune that with the K3 LINE IN to get to the right level. If you cannot obtain the 5th bar flashing, settle for 4 bars solid with the 5th bar not illuminated at all.

Only a WAG, Wes. All of the Elecraft radios write their current setup to RAM when you turn off the radio with its own power switch, and the next time the radio is turned on, that setup is applied. If, however, you remove DC power from the radio, those settings are NOT written, and the last settings saved will apply. Also, if the radio is running and power is interrupted for some reason, the radio can go a bit nuts. This happened to me once when I was running from the 12V line in my Toyota SUV without the motor running and power dropped for a few seconds when I started the motor. In my case, it locked up. Taking advice from K6XX, I removed power from the radio, let it sit for 20 minutes, and turned it back on. As I recall, that's all I had to do, and it fired up. 73, Jim K9YC From jim at audiosystemsgroup.com Fri Sep 8 20:01:42 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 8 Sep 2017 17:01:42 -0700 Subject: [Elecraft] KX2/KX3 built-in speakers In-Reply-To: References: Message-ID: <743d3f40-2025-88dc-b5dd-5d87887b38a0@audiosystemsgroup.com> On 9/8/2017 3:00 PM, Christopher Hoover wrote: > I find the KX2 audio level to be borderline in most field situations. It depends a lot on what sort of "field" you happen to be in. On a quiet mountaintop or spot in the woods, it's plenty good enough unless you happen to have much hearing loss. If the "field" is noisy (N6WM's example of surf on the beach is a good one) or if you're in a moving vehicle or parked along a busy road, it's probably not nearly loud enough. The KX2 and KX3 are designed for backpacking, so minimizing current drain is an important design objective. You'll appreciate this when studying that spec in the manual -- only about 150 mA on RX!? That means that you can run the radio a LOT longer on batteries, which reduces the weight you have to drag up the trail! 73, Jim K9YC From josh at voodoolab.com Fri Sep 8 20:11:28 2017 From: josh at voodoolab.com (Josh) Date: Fri, 8 Sep 2017 17:11:28 -0700 Subject: [Elecraft] TX Mode issue In-Reply-To: <9a2a6b45-1660-bfce-69ae-0cef3bda0c90@triconet.org> References: <9a2a6b45-1660-bfce-69ae-0cef3bda0c90@triconet.org> Message-ID: <223CC09A-AA2C-464C-9BD4-F9D59B49AF02@voodoolab.com> I had these exact symptoms.

In my case, the results don't lend themselves to a simple summary so I am sending this as a fair response to what I learned: 1. I'm quite surprised by the many respondents with homes over 2500 sq feet running satisfactorily off generators under 10 KW with several as low as 5 & 5.5 KW. One 3300 sq ft home was happy on 7 KW. Generator size ranged as you would expect from the portable Honda to the stationary GENERAC & KOHLER units. Natural gas as a fuel choice got the most recommendations. The overall lesson seems to be to "know your load" and buy what you need, not what you want. 2. I'm was pleased to hear K3, K3S & KX3 owners consistently reporting whatever hash their units were producing had no ill effects on their Elecraft radios during the period their generator was running. One engineer measured his no frills stationary generator as having about 4% THD. Most reported only the audible noise from their generator was noticeable while it was running (I suppose like a lawn mower doing the lawn outside). 3. No one reported having a GENERAC Syntergy unit. 4. The 1800 RPM Kohler was recommended the most over the more prevalent & cheaper 3600 RPM units. 5. Finally, most people were in favor of an automatic transfer switch for the whole house with installation done by a proper electrician. Sorry I can't give any more specifics. The reports of Elecraft working nicely with or without the generator running was refreshing. Thanks to all who responded.

KPA100 I will change 1N5711 diodes just to be safe. 73 de Jukka OH4MFA, OG4T 2017-09-08 19:27 GMT+00:00 Don Wilhelm : > Jukka, > > Measure the values of R59 (4.7k), R60 (100 ohms), R61 (120 ohms), and R62 > (2.7k). > If this is a K2 with a serial number below 3000, R60 will be a 100 ohm > potentiometer - set it to full counterclockwise rotation or replace it with > a fixed 100 ohm resistor. > > Even though 0.65 volts is slightly higher than I like to see it, that > voltage will be OK. > > 73, > Don W3FPR From pincon at erols.com Sat Sep 9 14:36:11 2017 From: pincon at erols.com (Charlie T, K3ICH) Date: Sat, 9 Sep 2017 14:36:11 -0400 Subject: [Elecraft] OT: Whole House Generator - Update In-Reply-To: References: Message-ID: <007001d3299a$8642bf20$92c83d60$@erols.com> It's Generac "Synergy" not syntergy And yes, they just came out with them as their own version of the inverter type generator. I've only seen it listed on a few of their dealers so far. There's nothing magic about wiring a transfer switch. In the larger systems of about 7 - 8 kW and higher, think of it as a remote sub-panel that might for example, be in a garage and fed out of your main house panel through an appropriate sized breaker, but with a two way switch for the Line In that selects either the line from the main panel or, the generator. This applies whether it is manually operated or fully automatic. All the control switching logic comes from the manufacturers circuitry. The whole idea is to NEVER permit your generator output finding its way out to your main feeders. (You could electrocute a Lineman working on what he thinks is a dead line. That pole-pig outside works both ways. You apply 240 V on your side and there is 7? or higher kV on that deadly wire!) Unless there is a massive failure in the switch itself, this can never happen. Most of the ones I've seen are WAY overrated for just that sort of safety margin. My panel came with a 15 kW generator, but has a 200 Amp transfer switch. The commercial power input is completely dis-connected from the generator much the same way as a DPDT switch's outer contacts never touch. In some of the smaller transfer panels, each house circuit has its own two way switch such that you have to manually switch it from mains to generator and back when the juice comes back on. This works fine too and isolates the generator output. 73, Charlie k3ICH -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Doug Hensley Sent: Saturday, September 09, 2017 1:44 PM To: Elecraft List Subject: [Elecraft] OT: Whole House Generator - Update Someone on the list suggested we post a summary of private responses to us as an alternative, I'm guessing, to members not knowing what was said. In my case, the results don't lend themselves to a simple summary so I am sending this as a fair response to what I learned: 1. I'm quite surprised by the many respondents with homes over 2500 sq feet running satisfactorily off generators under 10 KW with several as low as 5 & 5.5 KW. One 3300 sq ft home was happy on 7 KW. Generator size ranged as you would expect from the portable Honda to the stationary GENERAC & KOHLER units. Natural gas as a fuel choice got the most recommendations. The overall lesson seems to be to "know your load" and buy what you need, not what you want. 2. I'm was pleased to hear K3, K3S & KX3 owners consistently reporting whatever hash their units were producing had no ill effects on their Elecraft radios during the period their generator was running. One engineer measured his no frills stationary generator as having about 4% THD. Most reported only the audible noise from their generator was noticeable while it was running (I suppose like a lawn mower doing the lawn outside). 3. No one reported having a GENERAC Syntergy unit. 4. The 1800 RPM Kohler was recommended the most over the more prevalent & cheaper 3600 RPM units. 5. Finally, most people were in favor of an automatic transfer switch for the whole house with installation done by a proper electrician. Sorry I can't give any more specifics. The reports of Elecraft working nicely with or without the generator running was refreshing. Thanks to all who responded.

Rather than many individual replies, I'll just add further comments here. The SS-USB-100 USB-to-Serial converter (Prolific chipset) is definitely bad. As I said it worked fine before but is flaky now. With the Edgeport 4-port, FT8 works fine and I can connect using the K3 Utility program and do everything it should do, although I note that reading Macros from the radio is very sloooow, to the point that I thought it wasn't working. I've updated the K3 firmware to the latest version (it was only one behind).? I can use the utility program to turn TX Test mode on and off (SWH18) and it works fine until the mode gets set randomly. Someone suggested that the KPA500 TX Inhibit is enabled. It is not.? The KPA500 isn't on and the K3 is connected to a dummy load since I've been doing a lot of IMD testing. In other words, no RFI issues.? But, I am getting suspicious that this is an Auxbus issue in the K3. I removed the Auxbus cable and let the radio set for about three hours without a fault.? I reconnected it and removed the cover to check the I/O boards, etc.? It faulted immediately. I wiggled the boards and everything seemed OK.? I replaced the cover, reseated the cable and watched for a couple of hours.? No problems.? I thought that maybe it was fixed.? The XYL to be called me to a late lunch/early dinner and when I came back to complete this message reporting success, the TX Test light is blinking again. And again. I should note that the same cable is used on the K3S without issue. Wes? N7WS On 9/8/2017 2:47 PM, Wes Stewart wrote: > I've had to remove my K3S from the station again for repair.

This note is information to all who are using any soundcard digital modes. This is a situation of having too many controls that do the same thing (adjust the audio level). There are 2 in the computer - soundcard "speaker" level and the WSJT-X "power level". In the K3/K3S, there is the LINE IN gain. None of those controls should be set to either the extreme low range or high range. When adjusting, start with all at midrange values. Setting the soundcard level (Speaker or WSJT-X POWER slider) to a high value can create soundcard distortion. When the K3 LINE IN gain is at either at the high or low ends of the range, each increment of change will result in a large difference (dBs are logarithmic), so strive for a midrange setting of LINE IN (mic gain). 73, Don W3FPR On 9/9/2017 6:43 PM, MaverickNH wrote: > That seemed to do the trick Don.

Instead, it has a quadrature mixer which converts the incoming RF into baseband (or 8kHz IF) I/Q streams which is then sent to analog to digital converter. The output of the A to D converter is a 'bunch of bits', which can be manipulated by mathematical processes (DSP) to poduce most anything you wish. So the KX2/3 receiver is similar to a SoftRock receiver which feeds its output I/Q streams to a computer soundcard for DSP processing. With the KX2/3, the soundcard and computer are contained inside the box (no computer needed). That is the best I can explain "how it works". If your study of signal theory also included Digital Signal Processing, then look to the DSP algorithms for modulation/demodulation of all forms of RF signals. AM, CW, SSB, FM are all just mathematical formulas by which to manipulate data. The DSP process is more akin to the phasing method of detection. If you want an all analog comparison, look at the phasing receivers that Rick Campbell KK7B has designed. His receivers did "DSP" with analog circuits, and the weakness of that approach is only that analog devices have component tolerances, while mathematical formulas can produce exact results without those tolerances. 73, Don W3FPR On 9/9/2017 10:19 PM, K9MA wrote: > It's been a long time since I studied signal theory in college, but I'm > curious as to how AM is demodulated in a direct conversion radio like > the KX2/3.?

If the receiver is a little off-frequency, the I/Q vector rotates (because the phase is constantly changing) but the amplitude is still just the length of the vector.

I guess that means the image is 16 kHz away from the desired signal, and is suppressed by the I/Q demodulation, as in a phasing transmitter.? It does explain why the post mixer amplifier cutoff frequencies are so high. However, is not the KX3, when it's using the zero frequency IF really a direct conversion receiver, just with quadrature mixers so one side of zero beat can be suppressed?? Perhaps the term "Direct Conversion" is avoided because of the lack of opposite sideband rejection in conventional DC receivers.

Such filters get more complex if used at 8kHz. It also allows RIT/XIT excursion that is equal on each side of the carrier frequency.? In the KX3, it is +/- 15kHz, while with the 8kHz shift, the RIT/XIT range is +7 to -23kHz. What is termed "Direct conversion" is a detector/mixer that goes from RF directly to a single audio stream - it hears equally well on both the desired and undesired side of the carrier. In a Phasing or DSP based receiver, there are 2 outputs from the mixer - out of phase by 90 degrees to each other.? That allows the opposite sideband to be suppressed.? The process is done mathematically whether by DSP techniques or analog components as in the KK7B "R2" or the very old phasing detector transmitters and receivers available in the 1960s.? Central Electronics made some (including the "Signal Slicer" for a receiver adapter and worked at the 455kHz IF common in receivers of that day). 73, Don W3FPR On 9/9/2017 11:39 PM, K9MA wrote: > I didn't realize the KX2 used an 8 kHz IF, though I see it is > mentioned in the manual.?

But the original question was simply "what is direct conversion?" and the answer is, you convert the incoming signal to baseband ... directly ... one time.? What you do with the baseband after that is a separate matter.? And, you can hear SSB, CW, and AM just fine with a free-running, reasonably stable LO. My experience listening to an analog direct-conversion receiver in a low ambient noise environment is that the RX noise is uncharacteristically low, almost to the point that I thought something was wrong, like no antenna.? Then, tuning across a signal, it just sort of pops up at the expected volume.? Since I've only done this with one receiver, it's hard to draw meaningful conclusions however.

I think we have a winner.? Josh, W6XU, had asked me earlier whether I had TX Inhibit disabled.? I assumed in the KPA500, he was unaware of that function but was thinking about the inhibit in the K3,? I hadn't thought of that one. So I had sort of a perfect storm situation.? For some reason, TX Inhibit in the K3 was set to High.? How it got that way is beyond me, since I sure didn't set it that way on purpose and the default is Off.? If it is set to Hi then it requires a pull-up resistor, which of course it didn't have.? However, I had used a standard VGA cable on the K3 but opened the unused pins at the KAT500 end, which is completely functional. Last night I had removed every cable from the K3 except the power cable and the Aux cable and reset the K3. This morning the TX light was blinking.? Before seeing Josh's email I decided to break off the unused pins on the K3 end of the cable and shorted up the interconnect between the KAT500 and the KPA500. I suspected a transient problem. I think I was right.? I'm guessing that without a pull-up resistor and TX Inhibit set Hi there was enough garbage on the wire to cause the fault.? This probably was enough but Josh's tip and turning off the function is likely the real answer. Wes N7WS On 9/9/2017 5:23 PM, Wes Stewart wrote: > Thanks to all who offered suggestions.

It is difficult to say which one without doing some measurements. I would connect the K3 to a dummy load for the 1st test. Get a 'scope out with a 10x probe. The 'scope and probe should have a frequency rating of at least 3 times the operating frequency. A coax TEE adapter inserted in-line will give you access to the coax center conductor so you can read the RF voltage peak to peak value. That RF voltage should be used to compute the actual power developed by the K3. Compare that to the power reading shown on the K3 - you can use the formula {V(p-p) squared} divided by 400 to obtain the power in watts to a 50 ohm load. Derivation of that formula is "left to the student", but if you don't believe it, you can always convert to RMS voltage and calculate from there. Formula reduction is required before plugging in values. Once you know the actual power when the K3 reads 10 watts, remove the dummy load and connect the amp (leaving the TEE adapter in-line). Now send what the K3 indicates as 10 watts, and again measure the RF voltage. That will tell you whether the K3 power indication is correct or the amplifier indication is correct. 73, Don W3FPR On 9/10/2017 5:10 PM, Bill Frantz wrote: > I have just set up an Expert 1.3K-FA amplifier with my K3 (with most of > the upgrades to become a K3S).

My recollection from numerous amps that they may read OK (within 10 -15%) near full power, at low power they typically were way off. I suspect whatever calibration was done, if any, was at the high end of the scale. The load was probably pure resistive and near 50 ohms. By way off, I mean perhaps 50% not a factor of 3 like being reported. I wonder if anybody has any hard data on this. If it is true, why? In the old days with a non-digital meter, nobody could tell.... 73 de Brian/K3KO On 9/10/2017 21:32 PM, Don Wilhelm wrote: > Bill, > > I would say something is not calibrated correctly - either the K3 > wattmeter or the power determining device in the amp.

I got out my old Phillips 25 MHz scope and looked at the calibration sticker dated 1983. I decided to check the readout with a fresh alkaline battery and both the battery, checked with the DVM, and the scope looked OK. I did the measurements on both 20M and 40M, since 40M is less than half the scope bandwidth and got the same result. 6.4v p-p times 10 for the probe 10.24W, well within the margine of error for my measuring equipment. My conclusion is that this is a question for the Expert Amp people.

You may need to back down the AF and/or RF gain controls to hit a comfortable receive signal level. When AGC is ON, it compresses everything, both signals and noise, to the point that it?s sometimes hard to hear the true effect of blanking. This is especially true when multiple complex noise sources are present. With AGC off, you?ll better hear the effect of different noise blanker settings. As an example, I have a very high noise level at my QTH on 40 m tonight, a combination of narrow pulses (arcing poles), local light dimmers and appliances, and stochastic (atmospheric) noise. I turned the blanker on and initially thought it was having little effect. I then turned AGC off and was able to fine-tune the DSP and IF blanker settings on the K3S using my ears and the S-meter. An S-meter won?t tell the whole story. But in this case, my settings resulted in a 15 dB indicated reduction (about 3 S-units), and a definite improvement in weak signal copy. If you turn the AGC back on, noise blanker performance may be about the same in terms of improving S/N ratio of on-air signals, but turning it on/off will be a lot less dramatic due to gain compression. (Note: Don?t forget to turn the RF gain back up as required. This setting is a global value, not per-band, and you probably won't want the gain reduced on quieter bands.) 73, Wayne N6KR From k9ma at sdellington.us Sun Sep 10 22:51:34 2017 From: k9ma at sdellington.us (K9MA) Date: Sun, 10 Sep 2017 21:51:34 -0500 Subject: [Elecraft] KX2/3 DSP AM Demodulation In-Reply-To: <9d721120-44fb-db2c-4e20-08cab328556c@embarqmail.com> References: <36425e7f-92c9-6cd0-d66c-3fd7f5212d02@sdellington.us> <72369b3a-3ec9-ada6-95b0-0fcd498cbcda@foothill.net> <0757d365-8004-a900-2979-04fd30833019@sdellington.us> <9d721120-44fb-db2c-4e20-08cab328556c@embarqmail.com> Message-ID: <81cd93e6-e5a1-1248-9064-a3715dad56b9@sdellington.us> Don, OK, I'll turn that around, and ask why the KX2 does NOT convert directly to baseband, rather than to 8 kHz?? You said something about AM signals breaking in.? What's that all about?

You are free to call it what you will, but the rest of the world refers to that as an SDR. The 8kHz shift allows the opposite sideband and other garbage to be 16 kHz away from the desired signal where it is easily dealt with - no interfering results. 73, Don W3FPR On 9/10/2017 10:51 PM, K9MA wrote: > Don, > > OK, I'll turn that around, and ask why the KX2 does NOT convert > directly to baseband, rather than to 8 kHz??

That means yours is well within specification. That also means you should let it warm up for 15 minutes or so from a cold start. There is a means of adjusting the thermal compensation of the K2, but it takes a bit of experimentation, patience, and measurement. It involves changing the 1/4 watt resistor value on the Thermistor board. Download the PLL Upgrade instructions and look at page 4 of those instructions. Your K2 already has the PLL upgrade installed (I can tell from the serial number), but the upgrade instructions is the only place where the additional compensation adjustment is documented. Note that the first step of the instruction is to allow the K2 to warm up for 30 minutes. If your K2 does not drift excessively after a warmup period, you will not be able to improve it after the extended stability procedure. 73, Don W3FPR On 9/11/2017 9:13 AM, Curt wrote: > I built K2 s/n 06424 some time ago, then added KSB2 and finally converted it to 100W a few years ago.

I had planned to use the station as a portable endeavor when I first started acquiring it in 2013. However, a fall off the roof of my house has left me with significant orthopedic sequelae and it is time to sell. The station has never been outside my radio room. It sat on the operating desk with rare use. As of last month, the station has worked perfectly. All the components have the present firmware. I am a non-smoker. 1. KX3 SN 5351 Factory Assembled - All modules except the 2 M and 4 M modules. The NiMH charger has eight Eneloop cells in place, fully charged. There is a KXPD3 keyer. A complete cable set is included. SideKX panels are in place with the cover and a Nifty stand as well. The original panels are also in the package. There is a Heil Proset headset and Fred Cady book along with the original manual. There is a Nifty Mini-Manual. 2. PX3 SN 0052 Factory Assembled - SideKX panels in place, originals in the package with cover and a Nifty stand. Original manual and cables and a Nifty Mini-Manual. 3. KXPA100 SN 0549 Factory Assembled - Has the optional ATU installed. All the optional cables are present. Original manual and a Nifty Mini-Manual are in the package. I am asking $2,500 for the entire station. I am not interested in splitting the components. I will pay for packing, shipping and insurance in CONUS via UPS. PayPal is strongly preferred. Please contact me off-list at mike.n1md at gmail.com if seriously interested. 73 Mike N1MD From n6kr at elecraft.com Mon Sep 11 14:27:45 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Mon, 11 Sep 2017 11:27:45 -0700 Subject: [Elecraft] "HF Pack Lite": Remote control of KX2 via UP/DN buttons on the MH3 mic Message-ID: <07AA15D9-AEC3-4048-A65C-9D902827634A@elecraft.com> Use of an HF radio while walking, or at least while standing (perhaps taking in a view of the great outdoors), is generally referred to as ?pedestrian mobile.? Some operators even add /PM to identify as such. Two common forms of pedestrian mobile operation include: 1. HF Pack: This usually implies a radio carried in such a way that the front panel can be used and the display viewed at all times. Often a substantial antenna is used, as well as a large battery. This style of operation may require a specialized backpack and other hardware, and is reminiscent of military field communications. 2. HT-Style: This is as simple as it gets. Attach a whip antenna to your hand-held radio (e.g., KX2 or KX3), connect a trailing ground wire, and off you go. I?m interested in a third form that?s somewhere in between the two: 3. HF Pack Lite This is similar to HF Pack, in that the radio is worn in some fashion, but it?s optimized for light weight and simplicity. For example, it might involve: - placing the radio inside a small day pack, sling, or waist pack - using the radio?s own internal battery - a very lightweight antenna, such as a telescoping or flexible whip - simplified user interface, with just essential controls Combining all of the above, you get a minimalist station that allows for a lot more freedom of movement and won?t wear you out because it?s so lightweight. HF Pack Lite is also ideal for those (like me) who wish to remain under the radar during urban hiking. I recently made progress on my own HF Pack Lite station that others may benefit from. First, I found a great way to carry the KX2 or KX3: I?m now using a Patagonia Atom 8L Sling, purchased at REI. This bag is very small, has an internal compartment for the radio, and has a zipper that allows the antenna to emerge at the top. Being a sling, it has roughly the aesthetics of a ?quiver,? with a single strap you place over your neck and shoulder, like a camera bag. The only modification I made was to add a grommet at the bottom through which I pass the mic cable, earbud cable, and ground wire. I?m considering making a little harness for these to speed up connect/disconnect. Next, I?m working on a firmware release that will allow extended radio control via the MH3?s UP/DN buttons. Initially this will be added to the KX2, then to the KX3 after field testing. Here?s how it works: Each time you press the mic?s UP and DN buttons together, you advance through a set of mic-based operating functions. At present, these include: VFO control (default; this is what the UP/DN buttons already do) Key (hand key or keyer paddle using UP/DN buttons) Filter bandwidth (a few per-mode discrete selections) AF gain ATU tune Band Mode Morse code audio feedback is used to report the selected function. If you go through the selections rapidly, the Morse characters are truncated, so with a little practice you can quickly navigate to the function you want. Functions are arranged from most often to least often used. Other subtleties: * Anytime PTT is pressed, the menu resets to VFO control (a safe default). * Whenever the mic menu is used, all regular front-panel controls are locked out, preventing their accidental adjustment. (Thanks to Matt, W6NIA, for this suggestion.) All controls are unlocked if you power down and back up. * A long hold of the UP/DN buttons puts the KX2 into a ?standby? mode, at about half of its normal current drain. Another press of the UP/DN buttons restores normal operation. I started testing this yesterday. The small sling pack is a joy to use compared to bulkier backpacks. It stays in place surprisingly well, and with just a KX2 (1 lb with internal battery), it?s easy to forget you?re wearing it. The mic controls are very intuitive in both CW and SSB modes. One thing I have yet to find is a 4 to 5 foot ultra-flexible whip to replace the MFJ-1820. Ideally it would cover multiple bands. The MFJ whip is light enough, but it doesn?t coexist well with trees and doorways, and it?s still a bit too obvious for my taste. (See ?under the radar,? above.) In short, HF Pack Lite is a great way to indulge in a bit of radio while burning some calories, birdwatching, sightseeing, or engaging in post-apocalyptic Neighborhood Watch. Comments or suggestions welcome. 73, Wayne N6KR From jimk0xu at gmail.com Mon Sep 11 14:36:34 2017 From: jimk0xu at gmail.com (Jim Rhodes) Date: Mon, 11 Sep 2017 13:36:34 -0500 Subject: [Elecraft] kxv3 output question In-Reply-To: References: Message-ID: Can someone tell me the output range of freq for 10 meter if and power output level.

The frequency range is about 2MHz. I recall that initially the internal 2 meter transceiver design was to be for a 50MHz IF, but was later changed to a 28MHz IF which required switching between 2 crystals to cover the entire 2 meter band. That is a limitation imposed by the 10 meter bandpass filters. If that information is not correct, I am certain that someone at Elecraft will provide corrections. 73, Don W3FPR On 9/11/2017 2:36 PM, Jim Rhodes wrote: > Can someone tell me the output range of freq for 10 meter if and power > output level.

The Maldol AH-C14 is much lighter but the Watters-Stanton multi-band tapped coil could provide additional bands. My only concern would be strain relief. I can work on that. I do run and would love to use my Camelback which has externa rear Pocket which would easily handle the KX2. Running and operating aren't what I would intend to do, but I can run to destination and walk and operate on one of the bluff peaks in the neighboring park. If you would please send the firmware to me to FT. I have yet to test my conductive fishing pole idea with a conductive center wire. I lack some of the testing equipment to get it going. Thought I would have by now. 72 & 73, Bill K9YEQ, FT?er for K2, KX1, KX3, KXPA100, KAT500, W2, etc. -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wayne Burdick Sent: Monday, September 11, 2017 1:28 PM To: Elecraft Reflector Cc: KX3 at yahoogroups.com Subject: [Elecraft] "HF Pack Lite": Remote control of KX2 via UP/DN buttons on the MH3 mic Use of an HF radio while walking, or at least while standing (perhaps taking in a view of the great outdoors), is generally referred to as ?pedestrian mobile.? Some operators even add /PM to identify as such. Two common forms of pedestrian mobile operation include: 1. HF Pack: This usually implies a radio carried in such a way that the front panel can be used and the display viewed at all times. Often a substantial antenna is used, as well as a large battery. This style of operation may require a specialized backpack and other hardware, and is reminiscent of military field communications. 2. HT-Style: This is as simple as it gets. Attach a whip antenna to your hand-held radio (e.g., KX2 or KX3), connect a trailing ground wire, and off you go. I?m interested in a third form that?s somewhere in between the two: 3. HF Pack Lite This is similar to HF Pack, in that the radio is worn in some fashion, but it?s optimized for light weight and simplicity. For example, it might involve: - placing the radio inside a small day pack, sling, or waist pack - using the radio?s own internal battery - a very lightweight antenna, such as a telescoping or flexible whip - simplified user interface, with just essential controls Combining all of the above, you get a minimalist station that allows for a lot more freedom of movement and won?t wear you out because it?s so lightweight. HF Pack Lite is also ideal for those (like me) who wish to remain under the radar during urban hiking. I recently made progress on my own HF Pack Lite station that others may benefit from. First, I found a great way to carry the KX2 or KX3: I?m now using a Patagonia Atom 8L Sling, purchased at REI. This bag is very small, has an internal compartment for the radio, and has a zipper that allows the antenna to emerge at the top. Being a sling, it has roughly the aesthetics of a ?quiver,? with a single strap you place over your neck and shoulder, like a camera bag. The only modification I made was to add a grommet at the bottom through which I pass the mic cable, earbud cable, and ground wire. I?m considering making a little harness for these to speed up connect/disconnect. Next, I?m working on a firmware release that will allow extended radio control via the MH3?s UP/DN buttons. Initially this will be added to the KX2, then to the KX3 after field testing. Here?s how it works: Each time you press the mic?s UP and DN buttons together, you advance through a set of mic-based operating functions. At present, these include: VFO control (default; this is what the UP/DN buttons already do) Key (hand key or keyer paddle using UP/DN buttons) Filter bandwidth (a few per-mode discrete selections) AF gain ATU tune Band Mode Morse code audio feedback is used to report the selected function. If you go through the selections rapidly, the Morse characters are truncated, so with a little practice you can quickly navigate to the function you want. Functions are arranged from most often to least often used. Other subtleties: * Anytime PTT is pressed, the menu resets to VFO control (a safe default). * Whenever the mic menu is used, all regular front-panel controls are locked out, preventing their accidental adjustment. (Thanks to Matt, W6NIA, for this suggestion.) All controls are unlocked if you power down and back up. * A long hold of the UP/DN buttons puts the KX2 into a ?standby? mode, at about half of its normal current drain. Another press of the UP/DN buttons restores normal operation. I started testing this yesterday. The small sling pack is a joy to use compared to bulkier backpacks. It stays in place surprisingly well, and with just a KX2 (1 lb with internal battery), it?s easy to forget you?re wearing it. The mic controls are very intuitive in both CW and SSB modes. One thing I have yet to find is a 4 to 5 foot ultra-flexible whip to replace the MFJ-1820. Ideally it would cover multiple bands. The MFJ whip is light enough, but it doesn?t coexist well with trees and doorways, and it?s still a bit too obvious for my taste. (See ?under the radar,? above.) In short, HF Pack Lite is a great way to indulge in a bit of radio while burning some calories, birdwatching, sightseeing, or engaging in post-apocalyptic Neighborhood Watch. Comments or suggestions welcome. 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 Message delivered to k9yeq at live.com From markmusick at sbcglobal.net Mon Sep 11 18:15:07 2017 From: markmusick at sbcglobal.net (Mark E.

If that doesn't work, try setting the KAT500 to the factory defaults using the utility. My KAT500 has lost its marbles a couple of times and I find it easier to just set it back to the factory defaults and retune the memories for the two antennas I use it for. Also, you do not need to turn the KAT500 on before you turn on the K3S. That issue was fixed years ago in a K3 (not S) firmware update. I don't remember which one. It was before the K3S and the K3 SYN upgrade came out. You must have an old KAT500 manual, if that is where you got the information you need to turn the tuner on first. Go to the Elecraft website and down load the current KAT500 manual. If that bit of information is still in the current manual, it needs to be deleted.

Message-ID: <00d201d32b53$f4f87580$dee96080$@cox.net> Please reply off list only. For those who want to follow this discussion, just send me an email and I will be happy to include you on my own little list, that was established some time ago when I sought advice on replacing my central A/C system without generating RFI. After the previous discussion, I successfully had my old central A/C system, which was broken and non-repairable, replaced with a new system using old enough technology that it generates no RFI. However, that did not address the fact that my radio shack (which is a corner room facing south and west) is too hot to be comfortable during the hot season here in the Phoenix area (and that is true even *before* I turn on any of the radio equipment). Adding a conventional window A/C unit is not practical, as the windows in the room are obstructed by furniture and equipment. For the same reason a "portable" A/C unit (that stands on the floor, with a big hose connected to a window) is not practical. What should work is a "mini-split" room air conditioner. This consists of a condenser unit mounted on the outside of the wall, and a separate evaporator unit mounted on the inside. The units are connected together through just a small hole in the wall, maybe 3". These units are fairly new to the U.S. maket. Most people here don't even know that they exist. But when I searched homedepot.com I found that many different models are available, priced from under $1000 to several thousands. Home Depot sent an installer to my house. He told me that every model available uses variable speed motors, so I can't just buy a single speed unit in order to avoid RFI. Also, none of their customers would allow me to go to their house and let me listen for RFI while standing outside their house. However, he said these kinds of systems have been marketed in Europe for at least 20 years, and homes there either have no A/C at all, or they have mini-split's. So, all I have to do is talk to some hams in Europe, that have A/C, and ask what model they have, and whether it generates RFI. So far, I have discovered that my sister in Europe has a mini-split, but of course she cannot listen for RFI. So rather that turn on a radio and start searching for European contacts, I thought I would once again draw on this list. I know there are lots of Elecraft users in Europe, and surely some of them have A/C units. Please, guys, let me know how that is working out with respect to RFI! Again, please don't discuss on this list; I will be more than happy to include you in the discussion using my separate little list, and if you are kind enough to give me some information, but don't want to receive email, just let me know.

Feed the K2 with a broadband signal generator although noise on a portion of a band with no signals will also work. Compare the amplitude of the noise signal using the CW filter (width about 700 Hz is ideal) with the amplitude from the OP1 SSB filter. The amplitude should be about the same. If they are about the same, the filter is OK. Check the position of the filter passband (again with the noise source and the audio spectrum analyzer) - the filter should extend from about 300 Hz to 2300Hz if you have the older 2.1kHz width filter. If the newer 2.4kHz width, it should extend from about 300Hz to 2600Hz. Adjust the BFO to align the filter passband properly. For audio spectrum analyzers, you can use SpectrumLab or download Spectrogram from my website www.w3fpr.com. If the filter on receive shows near the same amplitude as the CW filter, then the filter itself is OK. Look for the problem at D14, R10, or R11 - check soldering. You should also check to be certain that the TXS signal from U1 pin 15 is at least 5 volts during SSB transmit. If not, replace U1. Try setting the SSBC parameter to 3-1 and see if the response improves. 73, Don W3FPR On 9/11/2017 7:53 PM, gt-i at gmx.net wrote: > Hello list, > I recently tried to use my K2 on SSB.

I don't think I've ever seen residential central A/C here. Common brands here are Mitsubishi, Daikin, Toshiba, and a bunch of others. Plenty of JA origin though most are locally manufactured. I have in my house a mix of Daikin, Mitsubishi and Fujibishi. 7 units in all. I can't say that any of them seem to add an amount of noise though the general background noise level is fairly high so it may well be masked. The one thing I was advised by a friend was to stay away from the units marked as inverter. These use switching inverters to control the speed and potentially could generate a lot more noise. A regular stepped speed analog unit should be okay in that respect. Martin, HS0ZED On 12/09/2017 02:16, Erik Basilier wrote: > Please reply off list only.

Not exactly. When using the USB port for CAT control of the radio, the RS232 (RJ45) port becomes a listen-only CAT echo of the responses sent by the K3S to the USB port. I am unfamiliar with the Acom amplifier's requirement for band info, but your amp will track K3S band data under the following conditions: - A conventional logging program is polling the radio on the USB port for band and frequency (which would result in K3S CAT responses emerging from the RS232 port) - The Acom is satisfied just hearing that CAT info (IOW - it does not generate it own queries and require responses. The SteppIR controller operates similarly ) -larry (K8UT) -----Original Message----- From: Steve Steltzer via Elecraft Sent: Tuesday, September 12, 2017 3:34 AM To: elecraft at mailman.qth.net Subject: [Elecraft] band data from the RS232 port while using the USB cable?

See the K3S manual for the pins. The only lines on the RS-232 line (or USB) are RXD, TXD and Signal Ground, and band data is present on the communications line when data is flowing because of communications with something like a logging program. 73, Don W3FPR On 9/12/2017 3:34 AM, Steve Steltzer via Elecraft wrote: > Brand new to the K3S. Is there a way to get band data to control an Acom amp on the RS232 port while using the USB cable? I had a lot of trouble with Win10 assigning the radio to ports already in use when I tried using the RS232 port. Going in and manually changing the port number in Device Manager didn't work. Finally got it working using the USB cable and I really don't want to go through all that hassle again to try and get PC comms working using the RS232 port. Apparently when you select USB in the menu, it shuts off the RS232 port?

Message-ID: <1ce763059cd7d1b9241d2eab163847b5.squirrel@www11.qth.com> I had five mini-split A/C units of various brands an my Aruba home and so did every neighbor. I never noticed any RFI. These are not new to the US, I had a Samsung mini-split heat pump installed in my garage over a decade ago. Mini-splits are very nice, you never have to get up out of your operating chair to adjust them and from a sound perspective they are very quiet.

For those who want to follow this discussion, just send me an email and I will be happy to include you on my own little list, that was established some time ago when I sought advice on replacing my central A/C system without generating RFI. After the previous discussion, I successfully had my old central A/C system, which was broken and non-repairable, replaced with a new system using old enough technology that it generates no RFI. However, that did not address the fact that my radio shack (which is a corner room facing south and west) is too hot to be comfortable during the hot season here in the Phoenix area (and that is true even *before* I turn on any of the radio equipment). Adding a conventional window A/C unit is not practical, as the windows in the room are obstructed by furniture and equipment. For the same reason a "portable" A/C unit (that stands on the floor, with a big hose connected to a window) is not practical. What should work is a "mini-split" room air conditioner. This consists of a condenser unit mounted on the outside of the wall, and a separate evaporator unit mounted on the inside. The units are connected together through just a small hole in the wall, maybe 3". These units are fairly new to the U.S. maket. Most people here don't even know that they exist. But when I searched homedepot.com I found that many different models are available, priced from under $1000 to several thousands. Home Depot sent an installer to my house. He told me that every model available uses variable speed motors, so I can't just buy a single speed unit in order to avoid RFI. Also, none of their customers would allow me to go to their house and let me listen for RFI while standing outside their house. However, he said these kinds of systems have been marketed in Europe for at least 20 years, and homes there either have no A/C at all, or they have mini-split's. So, all I have to do is talk to some hams in Europe, that have A/C, and ask what model they have, and whether it generates RFI. So far, I have discovered that my sister in Europe has a mini-split, but of course she cannot listen for RFI. So rather that turn on a radio and start searching for European contacts, I thought I would once again draw on this list. I know there are lots of Elecraft users in Europe, and surely some of them have A/C units. Please, guys, let me know how that is working out with respect to RFI! Again, please don't discuss on this list; I will be more than happy to include you in the discussion using my separate little list, and if you are kind enough to give me some information, but don't want to receive email, just let me know.

A couple of days of booth duty patiently and politely answering a wide range of questions is taxing enough but when you add setup and tear down its as much effort as a mini DXpedition. The second generation KPA 1500 definitely looks like it was worth the wait since the time I saw the original at Dayton. Hats off to the design crew for creating a new classic. I will order mine when the kit version comes out. As a television broadcaster, Over more years than I will admit, I have been involved with the deployment of numerous solid state high power transmitters and have toured several manufacturers development labs but never have I been able to put one together and I REALLY want that opportunity, even if it's solder free and doesn't save a lot of money.

It appears that many seem to make a simple solution much to complex. Stop and think about the elements or points that control audio levels. And don't forget, if you use the computer for other sound card applications, it may change levels. It may be necessary to make notes as to values or settings until you feel comfortable with each application. Here to assist.

However, I believe that I do have a fault in the KSB2 (Rev. D) or K2, since I know it behaved differently years ago. For example, the ALC shows 7 steady bars, no matter what power level I set nor how much SSB amplitude is produced. Regardless of the power level set, the RF signal is never stronger than 1 bar. I will try to experiment further, and I'm open to get any hints. Thanks! Gernot, DF5RF Am 12.09.2017 um 01:53 schrieb gt-i at gmx.net: > Hello list, > I recently tried to use my K2 on SSB.

My station: At the moment I have an Ameritron RCS-8V remote coax switch. I also have a remote ICE Model 516 antenna switch. I use the ICE to switch between the triband or the Ameritron controlled antennas. The Ameritron is controlled by 350' of CAT cable, hardline is from the house to the switch. My Ameritron controlled antennas are wires in trees, I also have a tribander which when I use it, I manually switch. All the antennas are tuned so there is no tuner other than the one in the K3s. I select the desired antenna thusly: 160M - 160 wire 80M --- 80 wire 40M --- 40 wire 30M --- 30 wire 20M --- 20 wire & tribander 17M --- 80 wire 15M --- 40 wire & Tribander 12M --- 80 wire & 160 wire 10M -- 160 wire & Tribander 6M ---- 160 wire & Tribander* * I have a homebrew addition of W1ZR's 6M passive elements added to the tribander. There are two transmit coax that exit the house; one to hardline leading to the wire antennas, the other is to the tribander. So here's the dilemma... I'm thinking of replacing the remote Ameritron switch with one that will automatically switch antennas as I switch bands, controlled by the K3s band change. If I decide to switch between the Tribander or wire, it would be nice to do that at the touch of a button but the ICE does a fine job. My Alpha 77SX is incredibly forgiving and if I don't make a proper antenna selection, nothing fails & I correct the problem & go. I am though considering the new Elecraft KPA 1500 amp (Do I really want to sell the SX or not... That is the question to my getting the new amp...) so why not make antenna switching foolproof and get an automatic remote antenna switch. I would though like to have one that does not require a control line.

So yes, USB may work OK, but you have a lot more flexibility with other modes when using DATA A. That allows you to set whatever you want for SSB and not have to change it when you want to operate digital - which should not use compression nor equalization to minimize distortion in the transmitted signal. 73, Don W3FPR On 9/12/2017 8:58 PM, Tommy wrote: > ?

Works great and I?m not relying on any Internet for time synchronization. One word of caution, be sure to turn off serial enumeration for the GPS COM port (if it uses one). Otherwise, Windows will think your GPS is a mouse due to some of the strings the GPS transmits. This ancient code Microsoft has in Windows to support plug and play of serial mice (who uses serial mice anymore? - I?m not sure you can even buy one these days). I believe the setting should be off by default, but not in Microsoft?s infinite wisdom. The serial port enumeration setting is found in the advanced settings for the COM port.

When I power on my K3S the KPA500 comes alive as well into the Standby mode. Standby is the setup PowerOn state so that is correct. It's as if the K3S is tugging the KPA500 Pin8 on the AUX connector but Pin8 on the K3S is an input rather than an output. Any idea what might be going on? It's otherwise working correctly.

There are other good ones. http://www.timesynctool.com/ The speed (frequency) of some computer clocks are more or less accurate than others, so the intervals between time sync required to stay in sync will vary from one computer to another. 73, Jim K9YC From ad8p at wcoil.com Wed Sep 13 12:40:03 2017 From: ad8p at wcoil.com (Bill Gaines) Date: Wed, 13 Sep 2017 12:40:03 -0400 Subject: [Elecraft] F/S New-in-Box P3 SVGA card and PR6 Preamp Message-ID: <5DB3EB0324B24DCAB88472F387A78C3E@BillPC> I have both items that are new and in the box.

Make certain your KSB2 has the PSK mod installed. Look at the schematic for the recent KSB2 and compare the values of C38, R4, R7, and R9 with what is installed on your KSB2. Also make certain you have adjusted the carrier balance for minimum carrier with no audio being transmitted. In SSB mode, close the DOT paddle to put it into transmit - the DOT signal and PTT are combined in the K2. It is best if you can monitor the carrier with an oscilloscope, but a monitor receiver will also do well, just adjust for minimum S-meter on the monitor receiver. 73, Don W3FPR On 9/12/2017 4:59 PM, gt-i at gmx.net wrote: > Hello again, > > Thanks to Volker, DL4ZBG, he replied directly with the following link: > http://www.qrpproject.de/Media/pdf/ZusammenfassungMods.pdf > It is a nice description of many improvements that can be made for the > KSB2. > However, I believe that I do have a fault in the KSB2 (Rev.

Why?? Because the other station can be off in the other direction, and what counts is the DIFFERENCE between you and the station you're trying to work. And the greater that difference, the less likely that you will decode each other, especially under weak signal conditions. Why?? Because the noise reduction schemes for JT65, JT9, and FT8 are synchronized to the beginning of the transmission period, and the decoding station needs to lock onto the sending station. Time sync is LESS critical for modes like MSK144 and ISCAT, which are primarily used for meteor scatter, decode from short bursts of signal, and do not depend on sync for their decoding. 73, Jim K9YC On 9/13/2017 1:38 PM, Lynn W.

Digital modes have standard sub-band or operating frequencies, so I set up my K3 modes (eg CW, SSB), including DATA-A selection for my favorite digital "channels". Example on 6m: I have 50.100 programmed for CW, 50.125 for USB, 50.200 for DATA-A (eme) and 50.260 for DATA-A (msk144). Of course the selection of digital modes is done in the sw (e.g. WSJT-X). I have several instances of my WSJT sw set up for different digital modes so I only need launch that instance of sw to be up and running on a given mode. Soundcard audio settings still need tweaking but the test signal selection in the sw makes that a quick function (I use an external soundcard with manual level controls). My K3 Line In is set to 10 which works fine for me. On 2m-eme I use MAP-65 which a different sw than WSJT, so 144.125 is set for DATA-A and I just launch MAP-65. Hope this suggestion might ease changing of modes for some of you. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From donwilh at embarqmail.com Thu Sep 14 07:19:51 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Thu, 14 Sep 2017 07:19:51 -0400 Subject: [Elecraft] Subject: Re: Setting the audio level for use in soundcard data modes.

You load an older firmware version as you would a new version. Bring up the K3 utility, point it at the firmware version you want and tell it to send the firmware to the K3. I have many of the older firmware versions. Prior to 5.50 I have 5.38, 5.29, 5.26. I can e-mail you which ever one you want. I do have further back than 5.26 if you find it too has the PTT change. Just let me know. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of n6ee Sent: Thursday, September 14, 2017 3:34 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] XMIT button not working?

These are ?VOX-only? modes, like hit-the-key CW, for historical reasons. Several PTT assertion cases were improved long ago, and this code has been in use by thousands of of K3/K3S users.

I don't know about the quality of "no-name" connectors in EU, but in NA, the quality is generally quite poor. When I got back on the air in 2003 after more than 20 years of inactivity, I re-stocked by parts stash with an assorted bunch of at least 40-50 adapters. Prices ranged from about $2 to about $3. Over a 4-5 year period, those connectors and adapters turned out to be junk that caused me nearly a dozen problems, many of which were not easy to troubleshoot or fix. There are many common defects. Pin diameters out of tolerance so that connectors don't mate reliably, dielectrics that melt when you try to solder, metals that don't take solder, connectors that physically fall apart, Tee connectors where the male and female center pin are connected by a tiny spring that melts with high power, intermittent connections, etc. Here in NA, Amphenol is the trusted mfr. They're more expensive, and the adapters are a LOT more expensive, but they don't suffer from the defects described above.? Likewise, vintage surplus MIL-type connectors and adapters (usually with type-numbers stamped into them) are still found at major hamfests, and are nearly always of very good quality. My absolute rule is, if it isn't one of those vintage MIL-types or if it doesn't say Amphenol, it's probably JUNK. Exception -- if you're a manufacturer and can verify the quality of parts from other manufacturers. Few of us fall into that category. There are similar issues with audio connectors. Neutrik and Switchraft are the good mfrs. 73, Jim K9YC From wes_n7ws at triconet.org Fri Sep 15 09:12:11 2017 From: wes_n7ws at triconet.org (Wes Stewart) Date: Fri, 15 Sep 2017 06:12:11 -0700 Subject: [Elecraft] OT: Looking for adaptor In-Reply-To: References: Message-ID: <484c932d-c5ad-f78b-1012-69d62d1cc951@triconet.org> Mea culpa.

It was first introduced at Hamvention earlier this year with a limited quantity available, but is now in production and available on our website. What is Key Line Pi? It is a mounting bracket that allows your Elecraft KXPD2 or KXPD3 paddle to be swiveled 45 degrees left or right to allow the operator to have a more comfortable keying position, while keeping the rig straight in front of you.

In particular, I'm trying to figure if the "Genius" can be controlled directly from the K-3 ACC using it's band data info. I'm controlling my 8x2 Antenna Genius from the per-band switched 12V outputs of two 5B4AGN bandpass filter band decoders. The 5B4AGN unit is driven from the K3 ACC output. The Antenna Genius is pretty flexible in how it can be controlled. There are dip switches that select the control logic. The manual is online, but when I was installing my Antenna Genius a year or two ago, the 8x2 was a brand new product and the manual wasn't as complete as it should have been, so I had to get pin-outs of the DB connector from Ranko via email. The Antenna Genius 8x2 has EXCELLENT RF performance, with greater than 100 dB isolation between outputs for any combination of selected outputs on all bands, and very low SWR. My measurements were done with a 50 Ohm VNA and all unused outputs unterminated, which is worst case. 73, Jim K9YC From k9fd at flex.com Fri Sep 15 13:41:08 2017 From: k9fd at flex.com (Merv Schweigert) Date: Fri, 15 Sep 2017 07:41:08 -1000 Subject: [Elecraft] 630 meter band open for use In-Reply-To: <41306a97-64d7-cc2b-042a-8bd37341391a@audiosystemsgroup.com> References: <15e8624d7f3-c09-795a@webjas-vad237.srv.aolmail.net> <41306a97-64d7-cc2b-042a-8bd37341391a@audiosystemsgroup.com> Message-ID: <5d7c6c27-79ab-47c1-3dc0-020ba25f0abc@flex.com> Since we finally have the 630 meter band open for amateur use, (after you file intent of operation with the UTC and wait 30 days), is there any plan to put this band on the K3/K3S band plan?

Message-ID: <01d535dd-c26f-8993-b73d-4026a56a9d64@effable.com> I am developing plans a hut-to-hut skit tour in Canada for next winter. On this trip, I will want to operate my KX2 inside of metal-roofed A-frame huts with a 60' feedline (RG-174, RG-58, or 300? twinlead?) to some kind of wire antenna outside. I plan to operate SSB on 40 & 20 meters at a minimum, and 15 & 10m if possible; likely in adverse weather conditions. I read the FAQ for the T1 on using it as a remote tuner, which says: > The T1 is intended for use near the operating position. But with a little effort it could be remoted, and its extremely small size would be beneficial for this purpose. First, the tuner must be placed in a weatherproof container if used outdoors. Second, controlling the tuner remotely requires a shielded control cable back to the operating position; this cable must supply, at minimum, a simple switch closure to wake up the tuner. It?s also possible to create your own band-data interface from the rig to the ATU, as explained in the T1 Owner?s Manual. Finally, you?ll need an SWR bridge at the operating position since you won?t be able to see the LEDs on the T1. I can see that the KX2 manual and the T1 manual give a lot of information about control signals and such. But before I take the time to try to engineer something or hack something, I'll ask the obvious question: Has anybody out there done this? Follow-up questions to anybody who has: Can you describe your set-up? Have any of you found a way to use the KXIO2 and either the PFn or some other feature to control the T1 from the KX2 through a separate 3-conductor cable? Thanks and 73s.

A no-loss transmission line and a full size dipole or vertical. With the small antennas (with respect for wavelength) that are typical for that band, very low antenna and transmission line efficiency is most likely quite low. EIRP is stated to account for those losses, and more power will be required. 73, Don W3FPR On 9/15/2017 7:23 PM, Mel Farrer via Elecraft wrote: > Interesting in reading the FCC notice, ALL modes are allowed!!! ?So some enterprising company should make a transverter for us??????? ?It is only allowing 5W EIRP, a signal generator and do +20 dBm, Hummmmmmm.

For receive purposes, either transceiver is fully self-contained. For transmit, you?ll need an external amp of some kind. RECEIVE The K3S, or a modified K3, will receive on this band via the XVTR IN jack (or RX ANT IN). You?ll need: - A KXV3 transverter interface module (standard with the K3S but optional for the K3) - A KBPF3A filter module, or a KBPF3 with a small mod (see KBPF3MDKT). The KBPF3A mod kit also comes with a capacitor to be installed on the K3?s RF board to suppress LF noise. RX performance is quite good on 630 meters. Note: The XVTR IN and RX ANT IN jacks work on 630 meters (472 kHz) because both are post-TR switch. The TR switch has high-pass filtering that rolls off starting around 1 MHz, so you can?t use ANT 1 or ANT 2. TRANSMIT You can get a transmit signal out on 630 meters using the XVTR OUT jack (same requirements as above). Our initial tests shows about 0.5 milliwatts. In this case you?d use XVTR IN for receive, not RX ANT IN. You?ll then need an external amplifier. It could be keyed using the rig?s KEY OUT jack. This signal could also be used to control a T/R switch if you needed to use the same antenna for both transmit and receive. If you use two different antennas, you?ll still have to cut the RX antenna off during TX, most likely. Firmware configuration: To use XVTR IN and OUT on this band, set up the radio for 160 meters, then set the CONFIG:KXV3 menu entry to TEST. This is necessary because 160 meter isn?t available as a transverter IF selection (yet). 73, Wayne N6KR From n6kr at elecraft.com Fri Sep 15 20:26:52 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Fri, 15 Sep 2017 17:26:52 -0700 Subject: [Elecraft] T1 as remote tuner for KX2/KX3?

Yes, you could use one of the general-purpose I/O signals from the KXIO2 module to activate a T1 ATU. The associated menu entry could be assigned to one of the four programmable function buttons. There?s no way to do full T1 control from the KX2, however, as that requires generation of a serial data stream. 2. If you were to use good quality twin lead or ladder line, you could obtain equally good results just using the KX2?s internal ATU option (KXAT2). This is exactly how I operate at my own station. I use an Elecraft BL2 balun between the radio and the feedline. (Coax from the radio to the BL2 should be very short.) In my case the feedline is connected directly to an off-center-fed dipole about 90? long. I can match this antenna on 80-6 meters with the ATUs in any of our transceivers. 73, Wayne N6KR > On Sep 15, 2017, at 10:57 AM, Steve Sergeant wrote: > > I am developing plans a hut-to-hut skit tour in Canada for next winter. > On this trip, I will want to operate my KX2 inside of metal-roofed > A-frame huts with a 60' feedline (RG-174, RG-58, or 300? twinlead?) to > some kind of wire antenna outside.

I'm astonished that the FCC permits phone on 630m. CW and digital is most efficient use of spectrum and weak signals. 97.313 https://www.ecfr.gov/cgi-bin/text-idx?SID=2689706e634fb3e73b9f4ef814c352e9&mc=true&node=se47.5.97_1313&rgn=div8 (l) No station may transmit in the 472-479 kHz (630 m) band with a transmitter power exceeding 500 W PEP or a radiated power exceeding 5 W EIRP, except that in Alaska, stations located within 800 kilometers of the Russian Federation may not transmit with a radiated power exceeding 1 W EIRP. So this observes that 630m transmitting antenna are expected to be very inefficient 500w resulting in < 5w erp. My inverted-L calculates to be 3w erp with 100w. So Mel +20 dBm (100mw) will result in about 3mw erp using my antenna.

But I assume you want to use the band decoder built in to the Antenna Genius, not a separate box, which means you're setting the dip switches on the Antenna Genius to "BCD" mode rather than "Pin to Port" mode. The K3 band data lines on the ACC port can indeed be used to drive the corresponding Band Data lines on an Antenna Genius set to BCD mode. But there are some issues: 1. Even though they both use the same DE-15 D-SUB connector, Elecraft uses pins 13, 3, 9, and 14, for band data (in that order, "Band 0" to "Band 3"), but the Antenna Genius uses Pins 11, 12, 13, and 14 (for "Band A" to "Band D"). This means you'll have to solder a custom cable, wiring Band 0 to Band A, Band 1 to Band B, etc., plus ground, instead of a stock DE-15 M/M cable. You could also use a pair of Y-BOXs and two stereo patch cables with the 4 RCA connectors wired to the correct Band Data pins at each end, if you don't feel like trying to solder tiny wires to those miserable high-density DE-15 connectors, but that's much more expensive. Time or money, pick your poison. 2. The K3 uses all band data lines low to represent 60m. The Antenna Genius does not recognize 60m at all (perhaps something that could be changed in AG firmware). All the other HF + 6m band decoding works the same as on the K3. 3. Biggest problem: Once you connect the Antenna Genius, no other device that reads the band data lines, such as a KPA500 or KPA1500, will follow the K3 band changes any more. That's because the Antenna Genius draws the voltage of the band data lines down much too low to be recognized by any other band-decoding devices wired in parallel (band data line voltage drops from +5V to about +3V as soon as you connect the AG). To solve issue 3 for Y-BOX customer WD4ASW, I built a custom prototype "Band Data Isolator" circuit that used the 12V output of the K3 to "boost" the BCD lines fed to the Antenna Genius, while isolating the AG's current draw from any other devices wired in parallel to the band data lines of K3 ACC port. I'm thinking about offering a new Y-BOX model that will have this isolator and appropriate pin wiring built in, just for Antenna Genius customers, so I can add you to the interest list, if you're interested. But I don't know how many other K3 owners want to use an Antenna Genius and Elecraft amplifier or other band decoder at the same time. Others should send me a private message, off list, if they want to be added to the "Y-BOX-AG" interest list. Wiring other band decoders like the Top Ten Devices Band Aide or the Elecraft KRC2 in parallel with a KPA500 causes no problems. The Antenna Genius is the only device I know about that needs special handling when wiring it in parallel. 73, Bob, N6TV https://bit.ly/Y-BOX On Fri, Sep 15, 2017 at 8:25 AM, Art via Elecraft wrote: > Anyone have experience using this combination?

Back in the days when shipping used these frequencies, only Morse was allowed for routine communications although modulation was applied to produce MCW for emergencies. That was a carryover from the days when some ships still used crystal detectors for emergency comms. Un-modulated CW produces no tone and at best soft clicks in a crystal receiver. But in those situations everyone had to QRT around the frequency of the emergency signal (usually 500 kHz) so sidebands were of no concern. It is true that a little bit CAN go a long way. Back in the 1990s when I was working on ships with MF CW gear I had the opportunity to share coffee with a radio operator and his captain who had spent hours circling in the Pacific looking for the source of an SOS on 500 kHz. It turned out to be a hand-cranked lifeboat transmitter in the Med.! They were chasing a phantom signal at the antinode half way around the world. The emergency transmitter ran a couple of watts at best into a very limited antenna hung by a kite or balloon over the raft. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Edward R Cole Sent: Friday, September 15, 2017 7:17 PM To: Elecraft Reflector Subject: Re: [Elecraft] 630 meter band open for use Bill, I could not believe it when you stated all modes allowed, so I checked the CFR47, 90.307 https://ecfr.io/Title-47/se47.5.97_1305 630m allows RTTY, data (see 97.307 (3) 630m phone and image (see 97.307 (1)(2) But seriously no 3-KHz phone should be used since one QSO would occupy nearly 50% of the 7-KHz wide band.

So this observes that 630m transmitting antenna are expected to be very inefficient 500w resulting in < 5w erp. My inverted-L calculates to be 3w erp with 100w.

There have been no interference reports. The ARRL was very conservative suggesting a 1 Kilometer standard for separation between an amateur radio station and transmission lines carrying PLC data in regards to non-interference. The truth is, shorter distances would still likely not produce interference. The FCC did adopt the 1 kilometer distance as a standard, however. '73 de JIM N2ZZ Aha!

The ones without the SVGA were saved from the P3 Utility. Those with the SVGA were saved to a USB thumb drive via the SVGA menu.? These data were all obtained by accumulating peaks on the signal. Before saving the screens, I used the cursor to points along the curve on both sides to document the frequencies and levels and wrote them down. Then I saved the screens. Note also that there are small calibrations along the top of the screen, and that these are sub-divisions of the scan width. Using graphics editing software, it's possible (not easy) to turn the screen grab negative so that the background is white and the traces are some color dark enough to print. When using these calibrations, it helps to set the scan width to a the smallest value that contains all the data and that makes these calibrations a convenient scale. When printing the graphics, it helps to scale the image so that the spacing between calibrations is the same or close to whatever ruler is available. Also, decimal rulers help. The edited graphics can be printed, vertical lines drawn, and points picked off with an architect's or engineer's scale. I've done this with some P3 data, and also ARRL Lab data for which data files were not available. Older engineers (those of us trained 50 or more years ago) learned these techniques (and a lot more) in our freshman year.? Data for Fig 2 in k9yc.com/TXNoise.pdf was obtained by applying these methods to the plots on Pages 1 and 2. If this sounds like a lot of work, you're right. Which gives you an idea how much time I put into producing those reports. :) 73, Jim K9YC On 9/16/2017 10:43 AM, Dave Cole wrote: > I am looking to impress a grid structure on the P3, as opposed to some > lines I need to move.?

I have the MFJ-212, but other similar devices should work also. It makes having a P3 even better. Before I bought my P3, I had been using a MFJ-212 MatchMaker to help me adjust my external tuner/matchbox. It applies a pulsing white noise across the spectrum. I have my P3 display the K3 frequency in the center of the screen. I was pleased to see that when the P3 is set to 200 Khz bandwidth, and as the tuner reaches a good match at the frequency of the K3, the pulsing white noise forms the shape of a ?V? on the screen or monitor. In a way, it becomes a piece of test gear. The shape of the Vee can be adjusted by moving the controls on the manual tuner until the best match is achieved. Ideally, the base of the Vee will bottom at the center of the screen. The shape or ?Q? of the Vee can reveal problems. Also from one day to the next, without touching the tuner, the Vee may be as far away as 40 KHz or more from the K3 freq due to changes in the antenna system (rain, frost, trouble, etc.) It gives a visual glance at the condition of my antenna system. After making a change to the antenna or open wire feedline, and I need to find the new tuner settings, I can watch as the color of the waterfall changes to help me see progress toward finding a match until the Vee begins to form. If I get a proper looking Vee, I don?t need to check the SWR because experience has shown it will always be a 1.0:1. I do glance at the SWR indicator on the K3 to verify it as I transmit. It can also show the behavior of my external ATU after it has tuned. (Keyword is external to the radio). I have only had one ATU to look at so far, and I hope others tune better. The best part is, I can tune without transmitting and while listening. No hurry, no worry. I can even ?tune up? on a QSO while listening to what is being said. Once again, FWIW.

From kl7uw at acsalaska.net Sun Sep 17 15:01:05 2017 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sun, 17 Sep 2017 11:01:05 -0800 Subject: [Elecraft] 630 MHz transmit and receive using the K3s or modified K3 Message-ID: <201709171901.v8HJ17Wa030644@mail41c28.carrierzone.com> Thanks Wayne. I have been using my K3 (SN 4043) purchased in 2010 on 495 to 502 KHz from 2012 as part of the ARRL Experimental 500-KHz Group using experimental license WD2XSH/45. Primarily using std CW or WSPR at about 4w ERP. Our experimental license specified using power up to 20w ERP so one had to calculate from EIRP. New ham regs now use EIRP which is typically shown if modeling an antenna using EZNEC. I modeled my 43-foot high by 122-foot long inverted-L which results in impedance at 503-KHz of Z = 0.83 - j886.5. I measured the antenna using my modified MFJ-269B at 18 - j0 after adjusting the base loading coil for resonance. Then get total radiated power from TPR = 0.83/18 * 100 = 4.6w (note my amplifier is running 100w into 50-ohm load). From EZNEC-5 antenna gain = 1.48 , EIRP = 4.6 * 1.48 = 6.8w ERP = 6.8/1.64 = 4.15w. Thus my antenna efficiency is only 4%. My unmodified K3 will only operate down to 490-KHz but I have the new synth board and mod kit for the KBPF3 to install which will extend operation to the new 630m band (472-479 KHz). I was able to get 1mw output with my unmodified K3 in TEST which I drove a modified NDB transmitter to 100w. The NDB is an aircraft CW beacon with dual xtal LO separated by 400-Hz. By CW keying that shift it produced a mcw signal. I removed he LO and simply capacitively couple about 0.1 mw to fully drive the three stage amplifier. I was able to pick up the NDB surplus for $40 which is self-contained with 55v PS. I expect them to quickly be snatched up by 630 ops. I home made a 10-inch by 11-inch base coil wound 1/4 inch spacing on a plastic form to provide loading. I have two taps which are moved between winter and summer soil conditions which shift the ground resistance enough to shift resonant frequency. I got about 5-Hz SWR bandwidth. Previous to the new mods, I ran a SDR-IQ receiver and only transmitted with the K3. I have picked up the CW signal from an Oregon station and my signal has been detected as far as Buffalo, NY. AFAIK only two commercial radio will operate on our new ham band: K3s (and mod K3) or theTS590. This opens a market for entrepreneurs to provide preamps, amplifiers and transverters. Puts Elecraft ahead of the "crowd", again! NOTE: FCC requires pre-registering with UTC before operating on 630m. Its a 30-day process. I'm waiting for my approval. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From n7tb at comcast.net Sun Sep 17 15:28:46 2017 From: n7tb at comcast.net (Terry Brown) Date: Sun, 17 Sep 2017 12:28:46 -0700 Subject: [Elecraft] OT: Rohn 25G Tower on tilt base. Message-ID: <64539A97-7571-43E3-B54F-D75BF3902B8C@comcast.net> Hello All, Please reply to me directly if you would please. We have far too many OT threads that take on a life of their own. I own a KX2, KX3, PX3, KXPA100, and K2. I love my Elecraft rigs. I have learned much from this list so thought I would ask a question. Background: I took down my 50 ft. Rohn 25G tower and Cushcraft ATB-34 beam (old) when I sold my house. I am building a new home and I am considering two setups for my tower. I don't want to climb a tower anymore and I am trying to keep my XYL happy by not putting up so tall a tower. I know it won't perform as well as before. Four horizontal ft. of my roof will be 23 ft. above the ground. The peak to the east is about 12 ft. from the tower. The rest of the roof is 20 ft. from the ground. The yard slopes downward to the east. The house is high on a hill looking east. To the west the ground is gently sloping up. I know my proposed free height (8-11 ft.) above the roof isn't ideal. Since I already have 5 sections of tower, I want to try to use them. Here are my two ideas. 1. Putting up two 10 ft. sections and a top 9 ft. section of Rohn 25G. I will mount a new Mosley TA 33-JR. on it with a mast putting the beam 2 ft. above the top section. This would put the beam about 31 ft. above the ground. My rotator is my reconditioned Alliance HD-73. I estimate the total weight of tower and beam at just under 200 lbs. I would like to put it on a tilt over base, either custom built or the Rohn if it can take the load. The tower would be attached to the house at the 13 ft. level, leaving 16 ft. unguyed. I would have a pulley system at the 12 ft level of the house to lower the tower. Is this setup something that will work? I am concerned about the load on the hinge on the base as the tower tilts over. 2. Put up one section of 10 ft. tower and a top section. Put an aluminum mast in place that sticks up 12 ft. above the top section. Everything else is the same. This reduces the weight a bit and has only 6 ft of unguyed tower. I just don't know how well 12 ft of mast above the top section will work. I would appreciate any advice anyone could give me. Thanks!

Have a K3s using USB to the computer & the internal card for digital modes. I wanted to work a few Q's in the RTTY contest and have been using WSJT-X for FT8 contacts. In the K3s WSJTX requires Data A for FT8 and in MMTTY it requires AFSK A (45BPS is normal). I went to use MMTTY after using WSJTX and with an excellent scope copy of the RTTY signals, gibberish is on the screen. I tried Reverse; REV in MMTTY and tried ALT in the K3 and no benefit. I tried so many things to decode in MMTTY but nothing worked until some random change in a K3s setting worked and then perfect copy as usual. I later clicked on WSJT to make a Q, the radio complied and switched to the settings for WSJT and when I went back to MMTTY, the copy was again gibberish. I don't recall what it was I did to set the K3s back so MMTTY can decode RTTY I did return it to AFSK A 45 but nothing decodes. It was a K3 setting that made the difference but I have no idea what it was I chanced on. anyone work out this issue yet when switching from WSJTX to MMTTY & the change in settings then required in the K3s?

Normally it defaults to 400 to 500 Hz, but your switch from DATA A to AFSK A may be confusing it. I cannot speak to interaction between WSJTX and MMTTY, but you may find something there in the switchover. Normally in MMTTY, you tune to a specific signal where in WSJTX you are setting to a wide bandwidth to view the waterfall of all signals in the passband. This is only a guess. Some control programs send commands to the K3 in the wrong order - changing modes before making a band change is one instance - that does not work with the K3/K3S. 73, Don W3FPR On 9/17/2017 3:37 PM, Gary Smith wrote: > Hard to enter a short subject that is > complete... > > Have a K3s using USB to the computer & the > internal card for digital modes. > > I wanted to work a few Q's in the RTTY > contest and have been using WSJT-X for FT8 > contacts. > > In the K3s WSJTX requires Data A for FT8 > and in MMTTY it requires AFSK A (45BPS is > normal). > > I went to use MMTTY after using WSJTX and > with an excellent scope copy of the RTTY > signals, gibberish is on the screen.

If not, the software is to blame. The sequence of commands (or lack of commands) sent to the K3 may be part of the problem. You certainly can use DATA A for RTTY if you shift to the ALT sideband, but the bandwidth will likely be set wide. Where are you trying o decode? on the K3 or on MMTTY? 73, Don W3FPR On 9/17/2017 3:37 PM, Gary Smith wrote: > Hard to enter a short subject that is > complete... > > Have a K3s using USB to the computer & the > internal card for digital modes. > > I wanted to work a few Q's in the RTTY > contest and have been using WSJT-X for FT8 > contacts. > > In the K3s WSJTX requires Data A for FT8 > and in MMTTY it requires AFSK A (45BPS is > normal). > > I went to use MMTTY after using WSJTX and > with an excellent scope copy of the RTTY > signals, gibberish is on the screen.

Sometimes using N1MM with MMTTY there is a bit of software change and PTT-KEY change but never just running MMTTY alone with the K3s. When I went to N1MM it was with AFSK A and it was already in the data mode as my last 20M Q was with WSJTX. Everything seemed normal in every way except garbage was what was being sent to the screen. Finally I tried to have the K3s decipher by changing the DATA MD to FSK D. Now the K3 was not deciphering either. Based on a suggestion that mentioned on-off... I shut down WSJT and MMTTY and retried and it worked for decode on MMTTY. Why that would have an effect on the K3s decoding I have no idea. I'll revisit the issue later this week, there's a RTTY contest coming up but for now while things are working, I'll enjoy the air a bit & make a few more Qs. If I find out anything helpful, I'll post that here for anyone with the same issues, later. 73 and thanks, Gary KA1J From alorona at sbcglobal.net Mon Sep 18 01:16:13 2017 From: alorona at sbcglobal.net (Al Lorona) Date: Mon, 18 Sep 2017 05:16:13 +0000 (UTC) Subject: [Elecraft] OT: Street lights - for US hams only References: <82738602.4042086.1505711773093.ref@mail.yahoo.com> Message-ID: <82738602.4042086.1505711773093@mail.yahoo.com> Yellow sodium vapor street lights can be a significant source of nighttime RFI on the lower bands. They are ignited at dusk by an RF arc that typically lasts between 5 and 10 seconds, the lamp lights, and the arc is extinguished. This arc noise sounds like a constant, dense static and is easily seen as a higher noise floor of up to 10 dB on the screen of a P3 panadapter or equivalent, depending on how far the street light is from your antenna. The problem occurs when the lamp reaches end-of-life. After turning on for the first time in the evening it will go off again after a period of seconds or minutes and must be ignited again. Therefore, every so often the noise floor suddenly rises, stays there for some time, and then returns to normal after the lamp re-lights. This cycle can repeat several dozen or hundred times per evening until it turns off for good at sunrise. 160, 80 and 60 meters are the bands most affected by these lights. I have been able to lower my ambient noise floor by several dB by going out on 'street light patrol' at night, armed with a flashlight, MP3 recorder and roll of bright orange tape. I drive around out to about a mile from my house looking for street lights that are cycling on and off. An efficient way to do this is to look for street lights that are off and watch them for a few minutes to see if they come on again, while listening on the car's AM radio for the characteristic interference. When I find an offending light, I use the flashlight and record the location, pole number, and any other important information on the audio recorder. Then I mark the pole with the bright orange marker tape and continue to search for other lights. On a good night, I can find 5 or more lights within a radius that I know can cause RFI at home. I have found that lights a half mile away will raise the noise floor only a couple of dB, while those within a block or two can add 10 dB to the noise floor. My local electric utility has a web site to report street light outages. I simply log in and transfer the information from the MP3 recordings to the form on the web site and submit the report. I'm extremely fortunate that my utility, Southern California Edison, faithfully replaces lamps within a business week of my report. They like several reports at once which makes it worth their while to spend a day replacing lights in one area, and they also appreciate the orange markers which helps them sight the poles easily. A few poles in my city are owned by the city, not the electric utility. In that case, I have made friends with the city worker in charge of taking outage reports and so I have someone to e-mail my reports to. Interestingly, the city can take several weeks to replace a bad lamp. [Government always seems to be less efficient than business.] I encourage you to be vigilant for sodium vapor street lights that could be a large source of HF nighttime interference for you.

Don't think for a second that these LED lamps were designed for low noise or that compliance with EMC standards will prevent unwanted interactions. A single LED luminaire is permitted to conduct and or radiate RF across HF up to and including 50dBuV, which equates to S9+15dB (S9 ~ 34dBuV into 50ohms). I'm now resigned to moving my HF station out and into a remote location that doesn't have these nasties with a bulls roar of my receiver.. Sad but true. 73 Matthew VK5ZM On 18 September 2017 at 14:46, Al Lorona wrote: > Yellow sodium vapor street lights can be a significant source of nighttime > RFI on the lower bands.

LEDs are low voltage devices, and the culprit is NOT the LEDs, but rather the SMPS (switch-mode power supply) used to convert the AC line voltage to the low DC voltage needed by the LEDs. OR, to be really cheap, only a step-down transformer driving the LEDs with no rectifier other than the LED itself.

I did eventually find one station that was decoding. It was a W7 station. That meant something was working. Then, I changed baud rate - set it to 75 and now I could decode most of the RTTY traffic I was seeing (some of the weak ones or the 45 stations - not so much). The source of most of the RTTY I was seeing at the time was the BARTG Sprint 75 contest. Maybe you ran into the same issue. 73.

The paralleled LMR-400 lines should produce a feedline characteristic impedance of 100 ohms. It is normal to connect the shields together at both ends. At the antenna, the connected shields are left floating, but at the rig end, are connected to chassis common (your BL2 ground lug) - perhaps "floating" is what you meant by "unterminated". Are the shields connected at the antenna end? As I recall, the matched impedance loss would be twice the loss of a single run of the coax, but at reasonable distances and the low loss of LMR-400, it should not be a problem at HF. The advantages of using parallel coax for a balanced feedline is the same as using coax over open-wire or ladderline. It can be run on or in the ground, run next to or thorough conducting metallic surfaces, or coiled up with no ill effects. Open wire and ladderline takes more care in its installation and must use gentle turns and be spaced away from nearby conducting objects. 73, Don W3FPR On 9/18/2017 6:02 PM, Wayne Burdick wrote: > > The experimental feedline, running under the house for half its length, was more deliberate if not justified in the literature.

I believe the loss is the same as a single run of coax. Each coax has only half the loss since it carries only half the power, but there are two of them so the total loss is the same. That assumes the SWR is the same in both cases. If 100 ohms is a better match than 50 ohms, then the loss will be lower in the parallel configuration.

It is the same as for a parallel line - the current is equal and opposite, so both conductors contribute to the loss. The total loss should be the same as two runs of coax, but that should be matched loss. This situation is likely mismatched loss - which according to the feedline loss with SWR can be relatively small, but present. Consult the charts in the ARRL handbook and the Antenna handbook for the loss due to SWR - for reasonable SWR and low loss feedlines it is minimal. The loss due to SWR is minimized for lines that have a small matched loss. The specification for LMR-400 is 0.7dB at 30 MHz for 100 feet, so it is small at HF. In contrast, RG-58 at 10 MHz has 3.6 dB attenuation at 10 MHz per 100 feet. I may be mistaken (it has happened before), but I am certain that the loss (in dB) is twice the loss in a single run of coax because the total length of coax is doubled. bottom line, with LMR-400 at HF that loss is likely minimal. For installations that would lead to sharp bends in ladderline or vintage 300 ohm line or close proximity to conducting surfaces, the use of parallel coax is a good choice for multiband antennas. Real open wire may be a better choice if it can be spaced with tension on the wires and run in spaces that are void of nearby conductors, but that is difficult to achieve in many situations. Wayne's "run under the house" may negate the advantages of using parallel conductor lines and make the parallel coax a better choice. Your situation may vary, but for low loss coax like LMR-400 at HF, that may be a good choice for multiband antennas. The only "problem" is the weight of 2 runs of low loss feedline to the antenna feedpoint. If the feedpoint is supported by a support pole, then that obstacle is not a problem. 73, Don W3FPR 73, Don W3FPR On 9/18/2017 9:19 PM, Alan wrote: > Yes, I agree the shields should be connected together at both ends. > > I believe the loss is the same as a single run of coax.?

The matched loss in parallel runs of coax, whether wired in series (to double the Zo) or in parallel (to divide Zo by two), is the same as for a single run of the same coax. The virtues of parallel runs are the lack of interference with surrounding objects and the impedance transformation of the series or parallel connection. 73, Jim K9YC From Gary at ka1j.com Mon Sep 18 23:22:29 2017 From: Gary at ka1j.com (Gary Smith) Date: Mon, 18 Sep 2017 23:22:29 -0400 Subject: [Elecraft] OT?

An OCFD is nothing more than a dipole cut for the lowest operating frequency with an off center feed. By doing this, it allows reasonable match for multiples of the fundamental frequency. If a center fed dipole is ~50-75 Ohms at say 80 meters, it will be somewhere around 700-1000 Ohms on even multiples. Feeding the antenna off the center just puts the feed at a point that reflects a more reasonable impedance. At this point there are two ways to go, the Carolina Windom way or the straight OCFD. I have used both configurations and they do really work well if you can get the antenna up in the clear. Feeding it with something like LMR-400 keeps the losses reasonable even with an SWR that may be 4 or 5:1. In both cases a 4:1 balun should be used, a current type if you use the simpler OCFD. Every Elecraft tuner I have used handles this without breaking a sweat. Happy DXing! 73, Barry K3NDM ------ Original Message ------ From: "Don Wilhelm" To: elecraft at mailman.qth.net Sent: 9/18/2017 10:20:22 PM Subject: Re: [Elecraft] Question for Wayne about your OCF Dipole >Alan, > >The loss is determined by the current in the coax, not that it carries >1/2 the power.

CATV coax is optimized for physical properties and for RF performance at UHF (CATV does include "backhaul" information from the customer for billing, etc., and that does run at HF). Nearly all CATV coax has a copper-clad steel center and a shield with braid and one or more foils. The shield is usually 100% Al. Loss in coax below UHF is all due to I squared R losses. The steel center causes increased loss at MF and low HF, while skin effect takes the steel out of the picture at VHF and above. And because it's Al, shield resistance is higher than for a good copper braid. Further, an important property of a cable shield is its transfer impedance, which is the ratio of differential voltage induced by current on the outside of the shield. In other words, its a parameter defining the effectiveness of a shield against common mode current. The lower the transfer impedance, the better the shielding, and the lower limit on transfer impedance is the resistance of the shield at the frequency of interest. That's an important reason for using common mode chokes on coax used for RX antennas! W8JI says that "RG6 cables can handle TX power," without qualifying which RG6 cables he's talking about (there are hundreds of them). I use CATV RG6 extensively for RX antennas, and buy flooded Commscope on 1,000 ft spools for about $95. While thinking about OCF dipoles, remember that because they are inherently unbalanced, they tend to pick up lots of noise on the feedline, and because they're nearly always fed with 2-wire line and usually a poor match on most bands, they are impractical to choke effectively. [To understand why, study my tutorial k9yc.com/RFI-Ham.pdf] No problem if you're in a quiet location in the middle of nowhere, but not a great choice if, like most of us, you're surrounded by neighbors, each with dozens of RF noise sources. 73, Jim K9YC From donwilh at embarqmail.com Tue Sep 19 00:03:28 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 19 Sep 2017 00:03:28 -0400 Subject: [Elecraft] Question for Wayne about your OCF Dipole In-Reply-To: <00a801d330f5$dd9de670$98d9b350$@erols.com> References: <000001d330c5$7af08530$70d18f90$@nwlink.com> <1371C400-FAFB-4F8F-ABEE-02AE3736DE39@elecraft.com> <000201d330d9$45958660$d0c09320$@nwlink.com> <00a801d330f5$dd9de670$98d9b350$@erols.com> Message-ID: <5b644d15-d026-fcfb-f89a-fd8b0390a68d@embarqmail.com> Charlie, The power handling efficiency of RG-6 is better than equal size RG-8X, so it should work well.

And if you are trying to operate it at frequencies below its halfwave resonance, it can be astronomical. I'm running a 10m long rotatable dipole, center fed, on all bands from 40 through 6m. There is no way this could work with any kind of coax feed; the SWR on 40m is around 100:1. The feedline is 34 feet (about 10m long). I discovered that the losses in a balun at the rig end are too great -- I nearly destroyed a 5kw rated DXE balun trying to do this (power was 1.2 kW). You need either a balanced tuner, or some balanced arrangement to cancel the reactance before the balun. I chose the latter. I recently upgraded my balanced feedline to no. 12 spaced 10 cm. I put a twist in it about every 1m to improve balance. Calculated loss on 40m (by far the worst band) is less than 2 dB.

I modeled my 43-foot high by 122-foot long inverted-L which results in impedance at 503-KHz of Z = 0.83 - j886.5. I measured the antenna using my modified MFJ-269B at 18 - j0 after adjusting the base loading coil for resonance. >> >> Then get total radiated power from TPR = 0.83/18 * 100 = 4.6w (note my amplifier is running 100w into 50-ohm load). >> From EZNEC-5 antenna gain = 1.48 , EIRP = 4.6 * 1.48 = 6.8w >> ERP = 6.8/1.64 = 4.15w. Thus my antenna efficiency is only 4%. >> >> My unmodified K3 will only operate down to 490-KHz but I have the new synth board and mod kit for the KBPF3 to install which will extend operation to the new 630m band (472-479 KHz). I was able to get 1mw output with my unmodified K3 in TEST which I drove a modified NDB transmitter to 100w. The NDB is an aircraft CW beacon with dual xtal LO separated by 400-Hz. By CW keying that shift it produced a mcw signal. I removed he LO and simply capacitively couple about 0.1 mw to fully drive the three stage amplifier. I was able to pick up the NDB surplus for $40 which is self-contained with 55v PS. I expect them to quickly be snatched up by 630 ops. >> >> I home made a 10-inch by 11-inch base coil wound 1/4 inch spacing on a plastic form to provide loading. I have two taps which are moved between winter and summer soil conditions which shift the ground resistance enough to shift resonant frequency. I got about 5-Hz SWR bandwidth. >> >> Previous to the new mods, I ran a SDR-IQ receiver and only transmitted with the K3. I have picked up the CW signal from an Oregon station and my signal has been detected as far as Buffalo, NY. >> >> AFAIK only two commercial radio will operate on our new ham band: K3s (and mod K3) or theTS590. This opens a market for entrepreneurs to provide preamps, amplifiers and transverters. Puts Elecraft ahead of the "crowd", again! >> >> NOTE: FCC requires pre-registering with UTC before operating on 630m. Its a 30-day process. I'm waiting for my approval. >> >> >> >> 73, Ed - KL7UW >> http://www.kl7uw.com >> Dubus-NA Business mail: >> dubususa at gmail.com >> ______________________________________________________________ >> 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 >> Message delivered to n6kr at elecraft.com > > ------------------------------ > > Message: 13 > Date: Sun, 17 Sep 2017 18:13:03 -0400 > From: Don Wilhelm > To: Gary at ka1j.com, elecraft at mailman.qth.net > Subject: Re: [Elecraft] OT?

Theoretical loop Z is 140-ohms so I was thinking parallel RG-11. Still have the big variable caps needed for the tuner, but I bought a old Drake MN2000 and now have the KXPA100 with atu for the tribander and inverted-V; Inverted-L has a tapped base coil. Well, short story: "in 2006 we moved to property with heavily forested 1-3/4 ac so loop idea was abandoned and I put up an inverted-L between two towers separated 130 foot". 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From kwroberson at yahoo.com Tue Sep 19 13:39:41 2017 From: kwroberson at yahoo.com (Ken Roberson) Date: Tue, 19 Sep 2017 17:39:41 +0000 (UTC) Subject: [Elecraft] 630M Antenna References: <689791639.5245208.1505842781354.ref@mail.yahoo.com> Message-ID: <689791639.5245208.1505842781354@mail.yahoo.com> For those interested in 630 meter , I use a 60 ft vertical.Photo on qrz dot com 73 Ken??

Some as low as 20 ohms. Yes, but that depends strongly on ground conductivity and electrical height. I'm part of a team that activates CA counties with few if any hams for the CA QSO Party, and do most of the antenna design work. The QTHs where we set up mostly have very poor ground, and I take that into account when modeling them in NEC. Our 40M dipole for the SSB station was rigged from trees at about 35 ft, and modeling predicted a feedpoint Z around 75 ohms, so we fed it with RG11 (it was a long run to minimize QRM to/from the CW station on 40M). When rigged, I checked SWR with an AEA SWR bridge calibrated to 75 ohms and the SWR was close to 1:1. That antenna at the same height over good ground modeled closer to 50 ohms. Using a vector network analyzer and SimSmith software to transform measurements in the shack to the feedpoint, I've measured the feedpoint Z of my 120 - 140 ft high 80M dipoles over poor ground in the range of 85-90 ohms. Feedpoint Z of horizontal antennas includes the mutual impedance of the ground reflection, and that reflection varies in both magnitude and phase with electrical height and ground conductivity. This can be clearly seen in graphs of computed feedpoint Z vs height for horizontal antennas, which show low dipoles oscillating around 50 ohms and high dipoles oscillating around 75 ohms. One place I recall seeing such graphs is in ON4UN's Low Band DXing, much of which is about antennas and counterpoise/radial systems for 40-160M. 73, Jim K9YC From K1ND at comcast.net Tue Sep 19 15:34:51 2017 From: K1ND at comcast.net (Jan) Date: Tue, 19 Sep 2017 15:34:51 -0400 Subject: [Elecraft] OT: G5RV trivia Message-ID: You are making me relive history Ken, K0PP; for in 1963 Jim, 9M2DQ sent me the 1957*/RSGB Bulletin /*with the article.

What a surprise; we all gained at least an S-unit between stations between Singapore, Malaya and Thailand. {you'll have to ask W8JVP about his*propagation* studies in Thailand}.

In an OCF the currents are not equal. 2) The two cables are operating in a (different and largely unknown) mismatched condition. Using ARRL publications for calculating additional loss due to mismatch is fraught with danger. As is I might add, using older versions of TLW software. (If you are an ARRL member and have a T1 line and infinite patience, I have neither, you can use the absolutely abysmal archive to read about this in the online June 2014 issue of QST.) 3) OK more than a couple. In a mismatched condition the loss isn't necessarily doubled for a doubled length. See http://ac6la.com/swrloss.html, for everything you need to know about this. Wes?

So here's the issue: My KX2 will show the power I've set with the knob precisely, right up to 110 watts. ?However, my KXPA100's green LEDs seem to be about 20 watts lower beginning at the 50 watt level. ?For example, when I've set the KX2 to 70 watts, the KX2 bar graph indeed reads 70 but the KXPA100 shows the green 50 watt LED. At 100 watts the KX2 reads 100 but the KXPA100 reads 80 watts. At 25 watts, the KX2 and KXPA100 indications are in agreement. I don't know which piece of equipment to believe. According to the KXPA100 manual (which ONLY refers to the KX3), it says the drive levels have been set at the factory against a laboratory grade KX3 and should not normally need to be messed around with. So is the KX2 calibrated in equal fashion at the factory or do I need to go through the CAL Pout routine for each band?? Anybody else run into this situation? ? 73, Stan WB2LQF From jim at audiosystemsgroup.com Wed Sep 20 00:06:56 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 19 Sep 2017 21:06:56 -0700 Subject: [Elecraft] Specs KIO3-B internal sound card In-Reply-To: <57a7b50b-07af-537f-58a2-54d39640f94e@dk5ya.de> References: <57a7b50b-07af-537f-58a2-54d39640f94e@dk5ya.de> Message-ID: <9fc660d4-a7d7-974d-a472-7665fceee556@audiosystemsgroup.com> On 9/19/2017 3:55 PM, Udo Langenohl - DK5YA wrote: > compared to high quality external devices SNR and THD+N is rather > poor.

Don't fall into the trap of "specsmanship" and thinking you need cutting edge audio products for ham radio, which is a FAR less demanding application. WSJT-X operates at 48 kHz 16-bit, no matter how exotic your sound card, the ~90 dB dynamic rangeand 5 kHz audio BW are more than sufficient for the audio I/O for the digital modes used in ham radio. I can't comment on audio distortion -- I haven't bothered to add a KIO3B to my vintage K3s. IMO, THD+N doesn't matter, THD and IM do. Greater sampling ratesand a few more bits ARE useful for the I/Q signals needed to drive spectrum displays, but the K3S does not provide I/Q data via the USB port. Great engineering is buying only what is needed for good performance, not paying for stuff you don't need. 73, Jim K9YC From JimMiller at STL-OnLine.Net Wed Sep 20 00:36:16 2017 From: JimMiller at STL-OnLine.Net (Jim Miller) Date: Tue, 19 Sep 2017 23:36:16 -0500 Subject: [Elecraft] Are the internal 2m Transverter and the external XV144 the same internally?

While EME needs every last fraction of a dB of RF performance, the same is not true of an audio interface used for JT65. In this respect, EME is less demanding than day-to-day HF operation, where the passband may have 20 or more signals of widely varying strengths. As long as you follow the WSJT-X authors' advice about setting levels, a consumer-grade audio interface such as that in the KIO3B is more than adequate. A studio-quality audio interface will add nothing to the performance of your station. WSJT-X requires audio input as 16-bit linear PCM, sampled at 48 kHz. (The next thing it does is to downsample to 12 kHz.) So there's no advantage in greater bit-depths or sampling frequencies. 73, Richard G4DYA From richard at lamont.me.uk Wed Sep 20 04:16:37 2017 From: richard at lamont.me.uk (Richard Lamont) Date: Wed, 20 Sep 2017 09:16:37 +0100 Subject: [Elecraft] Specs KIO3-B internal sound card In-Reply-To: <9fc660d4-a7d7-974d-a472-7665fceee556@audiosystemsgroup.com> References: <57a7b50b-07af-537f-58a2-54d39640f94e@dk5ya.de> <9fc660d4-a7d7-974d-a472-7665fceee556@audiosystemsgroup.com> Message-ID: <889cff95-f343-6452-5940-7c53be4dde60@lamont.me.uk> On 20/09/17 05:06, Jim Brown wrote: > WSJT-X operates at 48 kHz 16-bit, no matter how exotic your > sound card, the ~90 dB dynamic rangeand 5 kHz audio BW are more than > sufficient for the audio I/O for the digital modes used in ham radio. When operating JT65 or FT8 on HF, and having (as recommended) turned AGC off and adjusted the K3S's gain to set the level to 30 dB on WSJT-X's 'thermometer' on white noise, I've had strong signals drive the system over the clipping point on HF. This can occur with either a very strong local signal or 1000km+ sporadic-E. IMHO the 16-bit dynamic range of the KIO3B and WSJT-X's internals are not quite good enough for these fortunately rare occurrences. Another 10 dB would suffice, but achieving it would of course require changing the whole chain from ADC onwards. 73, Richard G4DYA From w0eb at cox.net Wed Sep 20 07:53:55 2017 From: w0eb at cox.net (Jim Sheldon) Date: Wed, 20 Sep 2017 11:53:55 +0000 Subject: [Elecraft] Specs KIO3-B internal sound card In-Reply-To: References: <57a7b50b-07af-537f-58a2-54d39640f94e@dk5ya.de> Message-ID: Udo, I've been using my K3S on FT-8 with great success via the K3S' internal soundcard.

Different boards, different size, different logic, different adjustments. The XV144 design point is for CW/SSB at the lower end of the band. The K144XV covers the entire band and switches crystals half-way. It will do FM. The XV144 can be used with most any rig and can be driven to full power with less that 1mW or up to 8 watts. There are jumpers to set the innut power level. It can also use either split 28MHz IF or a single coax. To the 144MHz antenna, you can use either one coax or a separate ones for TX and RX. The XV144 is thru-hole construction and it must be assembled piece by piece. The K144XV is SMD and if a kit, you assemble the board and enclosure and plug in the cables. 73, Don W3FPR On 9/20/2017 12:36 AM, Jim Miller wrote: > Are the internal 2 meter Transverter and the external XV144 the same > internally? > Is it the same board in each? > > Same logic but different board layout? > > Adjustment differences? > > > > Thanks, Jim KG0KP > > ______________________________________________________________ > 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 > Message delivered to donwilh at embarqmail.com > From dk5ya at dk5ya.de Wed Sep 20 11:36:10 2017 From: dk5ya at dk5ya.de (Udo Langenohl - DK5YA) Date: Wed, 20 Sep 2017 17:36:10 +0200 Subject: [Elecraft] Specs KIO3-B internal sound card In-Reply-To: References: <57a7b50b-07af-537f-58a2-54d39640f94e@dk5ya.de> Message-ID: <6366e953-8851-a0bf-2609-2a11c9b99189@dk5ya.de> Sounds good, gonna give it a try next week and will compare external stuff / internal stuff and let the group know.

Rudy moved a couple years ago to new property and has new antenna farm. I believe his study of elevated grounds was published in QEX and later in QST. Virtually all transmitting antenna for 630m will be "short" verticals so his findings are useful if you consider getting on 630m. EZNEC-5 indicated my radiation resistance would only be 0.83 ohms with a 43-foot high top-loaded vertical. Actual measurement showed 18 ohms so efficiency is 0.83/18 = 0.046. My ground plane is woefully too small: four 70-foot by 2-foot wide runs of chicken wire on ground. But most hams have too little acreage for anything even close to 1/4 WL (521-foot). My antenna consists of three parallel vertical wires spaced 1-foot apart and shorted by a 1/2 inch copper tube at both top and bottom; horizontal leg is two parallel wires spaced 2-foot and 122-foot long (like-wise with copper tube shorting bars). The parallel wires lower Q a bit to widen the SWR bandwidth which is about 5-KHz. Extra horizontal wire increases top-hat capacitance which makes vertical look longer. I will make a new webpage to show what I am using on 630m (old webpage was hacked several years ago and I never resurrected the 600m page). I may still get my inverted-L repaired and rehung with aid of my prof. tower person, though winter wx is not far off up here (freezing temps expected within a week). 73, Ed - KL7UW I will probably play with running WSPR and the new FT8 digital modes on 630m.

If you see a significant voltage drop, the first thing to look for is a bad shield connection between the shield and connectors. Right now, you have too many variables in the 'equation' - follow the steps below to find out what is working and what is not: Take a dummy load out to the tuner and connect it to the coax, then see if the power and SWR are decent. If not, work on your coax - but before that, take the dummy load and connect it with a short known good jumper to the KXPA100 and see what power and SWR are shown on the KX2. If it shows good power and SWR at the far end of the coax, then check your tuner and antenna to make sure it has good connections at all points. Disconnect the parallel feedline from the tuner and use 2 dummy connected together with a TEE adapter to create a 25 ohm load. See if your tuner matches it on all bands of interest. If the KXPA100 still does "funny things", then try the KX2 alone into the dummy load (removing the KXPA100 rather than just putting it into bypass). That will either isolate the problem to the KX2 or the KXPA100 - or prove them to be OK. Most problems of that nature will eventually trace to something having to do with the coax and antenna system.

The RX and LO parts are almost completely taken over from the XV144 so you can expect a similar level of RX performance from the K144XV. Contrary to the XV144 the TX/RX switching inside the K144XV is implemented by using PIN diodes, which is smaller, faster and not really a drawback in terms of IMD. To further reduce the K144XV size the TX driver and final amps have been completely replaced by discrete stages rather than using a RF module as in the XV144. The design of these high gain discrete power stages under space constraints can be a challenging task, since unwanted coupling between components might cause oscillations. As there are no dedicated control lines connected to the K144XV, the transverter functions are handled by the KXV3A interface via DC voltage levels and pulses on the IF in/out lines. TX/RX switching is maintained through an overlayed DC voltage on the receiver IF line, whereas the transverter ON/OFF and LO range control is managed through different length DC pulses on the transmitter IF line."

At first glance many look much like today's wire antennas. One or more horizontal wires above the home with a "feed line" leading up from the shack (often in the attic). But looks are deceiving. The "feed line" is actually the antenna - a short vertical antenna - connected to the horizontal wires for "top loading". A robust matching network (a.k.a. "tuner") completes the system. Very inefficient, but also very effective under the right conditions. However, it's clear that once HF propagation was discovered Hams stampeded onto the "short waves" for a reason. 73, Ron AC7AC From eseeliger at earthlink.net Wed Sep 20 19:49:11 2017 From: eseeliger at earthlink.net (Edward Seeliger) Date: Wed, 20 Sep 2017 18:49:11 -0500 (GMT-05:00) Subject: [Elecraft] KX3 Cruiseship Antenna (Rx) Message-ID: <33134178.30985.1505951351879@elwamui-hybrid.atl.sa.earthlink.net> Does anyone have experience or suggestions for an antenna to use with a KX3 on a cruise ship for receiving?

Minor changes to a particular menu item may happen more frequently. Look at the firmware release notes - any changes to the menu will be noted there. That is the source of the very latest information. You can write any change information in your manual menu listing on pages 35 through 41 in your KX3 manual. When the manual is updated, that information should be included. Look at the manual errata pages too. The errata is updated more frequently than the manual itself. If you find multiple versions of the errata, you do not have to keep earlier ones for that particular version of the manual. 73, Don W3FPR On 9/21/2017 1:19 PM, Keith Hamilton wrote: > Could anyone please direct me to an up-to-date menu listing for my KX3 that > I could print? > I have seen several and looked at the KE7X books but none seem to be > up-to-date as of > MCU version 2.76. > > I hate looking all over for corrections to the old menu versions available > on the net. > > For that matter is the Elecraft KX3 Owners Manual menu chapter up-to-date? > > Thanks for any help!! > > Confused in Ohio!

I have a Kx33 to power my K2/10. If I remember correctly, it is rated 14.4 V at 4 Amps. For K2 owners who have the internal battery, he has an adapter you can purchase that will reduce the voltage to 13.8 Volts for battery charging. It is a very good power supply. You will not be disappointed if you acquire one. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of MaverickNH Sent: Thursday, September 21, 2017 7:30 PM To: elecraft at mailman.qth.net Subject: [Elecraft] Kx33 PSU for KX2?

Lauderdale-->6Y-->P4-->HP-->TI-->XE [x3]-->Los Angeles.? Bought the KX1 to take on the trip 15 day trip. I wrote to Princess Lines with the radio specs and photos.? Answer by telephone was "Absolutely not!? It might interfere with operation of the ship and you could start a fire."? On the principle that "the Captain runs the ship," I took the rig, contacted the Purser's office after we were aboard, and a very young junior officer came and looked at my radio.? Once he knew the power and frequencies, he said, "You have permission to operate your amateur radio set but not in public spaces, and do not remove any paint," and wrote this in my log. This confined me to the "balcony" outside our stateroom, which would more properly be called a "shelf," maybe 4 m x 1.3 m or so. I had chosen to take my 8 m wire+counterpoise made by peeling the braid back on RG-58 since the MP-1 knockoff I have looks suspiciously like a pipe bomb on the x-ray.? Stringing 8 meters of wire in a 2 meter square hole in 3 cm thick steel proved to be a challenge.? Doing so in a configuration that would actually radiate was an order of magnitude harder.? It did work, I managed about a dozen Q's with So. Americans [the ship was between me and NA all the way].? I've never taken a radio on a cruise again. I used a 4S1P LiFePO4 battery with no way to charge it, but I didn't come close to depleting it.? 15 days on the Big White Boat was about 5 days too many.? The Canal was great.?

In-Reply-To: References: Message-ID: <4D9715F8-7889-416C-B584-1A2DE05D381C@elecraft.com> Hi Anne, Congratulations! As the principal designer I can make a few suggestions: - Keep the preamp on most of the time. As with most quadrature downconversion radios, this dramatically improves the S/N ratio. Turn off the preamp and/or turn on the attenuator only if you have very strong signals to contend with (like a nearby ham or broadcast station). - If you?re a CW op, be sure to try CWT (CW tuning), which can tune in signals automatically when you tap SPOT. Also try APF (audio peaking filter) for CW. It?s a very narrow filter, but works like magic on really weak signals. - Data modes are a lot of fun. There?s an RTTY contest this weekend, so by all means tap DATA, select FSK-D mode, turn on text decode using the TEXT switch, and practice tuning in some RTTY signals. You?ll them from about 14080 to 14100 kHz during contests; otherwise, typically 14080-14090. RTTY stations will be decoded and displayed right on the radio?s VFO B display. You can transmit in this mode using the keyer paddle (or the terminal function of KX3 Utility). You can decode/display/send CW and PSK31/PSK63 in the same way. - If you?re not hearing much on the bands, check WWV at 5.0000, 10.000, 15.000, and 20.000 MHz. These give you a rough idea of what conditions are like. I find that if WWV is S9+10 dB or stronger on a given frequency, the nearby ham bands should have activity. If not, start it! Call CQ. Also try listening for 6 and 10 meter beacons if there?s a high-frequency opening. Dxmaps.com is a great tool for watching for openings. - The KX3?s LCD is transflective, which means you can read it in direct sunlight. You?ll need to take the radio outdoors for this purpose, and of course that?s what we designed it for (hint!). Of course the display also has a backlight for indoor and nighttime conditions. - I hope you won a KXAT3 ATU, too! This makes all the difference when operating portable. - You can use any type of AA batteries internally, but I?d recommend Lithium non-rechargeable 1.5 V AA camera batteries. OTOH, if you have the internal charger, you *must* use NiMH cells. When running from internal batteries, recommended power level is 5 W or less. With an external supply you can run up to 15 W on 80-15 m and 10 W on the other bands. Have fun! 73, Wayne N6KR > On Sep 21, 2017, at 9:54 PM, Anne Dirkman wrote: > > I've had my license since 2011 with very little exposure to amateur radio > before that - pretty much started from scratch...

I suspect that you have either a faulty paddle or it's just badly adjusted, with the contacts too close. I've had a paddle give strange results, where one paddle pulled on the wiring when operated, which in turn pulled the wire on the opposite paddle and made it operate too. AFAIK there's nothing in software/firmware to allow that behavior to be set. 73, Alan.

They are available in printed form from Elecraft or a .pdf version at the link Vic provided. It is a real study guide for the operation of the KX3, and as such contains exercises to help you learn all about it. If you go from start to finish, you will know about everything concerning the operation of the KX3 under various operating conditions. As Vic indicated, the manual contains everything, but is more of a manual than an operating guide if you are not familiar with HF operation. 73, Don W3FPR On 9/22/2017 6:22 AM, Victor Rosenthal 4X6GP wrote: > I have the K3 book in this series, and it helped me enormously.

I have used my K3 and MMTTY for RTTY mode communications for a long time. I used MMTTY as a standalone program, I used it imbedded in N1MM classic and I also used it imbedded in my logging program Logger 32. Life has gotten in the way of operating and as a result I haven?t been on RTTY for several months. Well this past weekend there was an RTTY contest on and I had a few minutes to get on so I turned the rig on and brought up one of the programs to get on and have some fun. Well I couldn?t make any of the three show me the XY scope. it was just a small dot in the middle of the screen. I could transmit OK and would decode on the screen of the radio but I can?t seem to get it going again in MMTTY. Is there someone using any of these three programs that could help me discover what setting I am missing either in the software or the radio?

The generic setting information provided in the digital program instructions Will Not Work for the KX3. ALC in Elecraft radios works differently than any other major brand of tranceiver. 3.

There?s an RTTY contest this weekend, so by all means tap DATA, select FSK-D mode, turn on text decode using the TEXT switch, and practice tuning in some RTTY signals. You?ll them from about 14080 to 14100 kHz during contests; otherwise, typically 14080-14090. RTTY stations will be decoded and displayed right on the radio?s VFO B display. You can transmit in this mode using the keyer paddle (or the terminal function of KX3 Utility). You can decode/display/send CW and PSK31/PSK63 in the same way. > > - If you?re not hearing much on the bands, check WWV at 5.0000, 10.000, 15.000, and 20.000 MHz. These give you a rough idea of what conditions are like. I find that if WWV is S9+10 dB or stronger on a given frequency, the nearby ham bands should have activity. If not, start it! Call CQ. Also try listening for 6 and 10 meter beacons if there?s a high-frequency opening. Dxmaps.com is a great tool for watching for openings. > > - The KX3?s LCD is transflective, which means you can read it in direct sunlight.

OTOH, if you have the internal charger, you *must* use NiMH cells. When running from internal batteries, recommended power level is 5 W or less.

That in turn could have a number of explanations. First, check that the audio cable between the rig and the sound card is connected correctly and seated properly in the connectors. Next, check that the correct sound card is selected in MMTTY. Windows can and does change the list of sound cards, so this is not a set it once and forget it setting - re-check it any time something goes wrong with the audio. If the correct sound card is selected and the physical connections are OK, check levels. Check the K3's LIN OUT level in the CONFIG menu. If there is a physical control on the sound card device, make sure it is not turned all the way down. In Windows, check that the sound card has not been disabled, and that the Windows level setting for the receive (recording) sound card is correct/reasonable. 73, Rich VE3KI AD8P wrote: I need some help.

Life has gotten in the way of operating and as a result I haven???t been on RTTY for several months.

Well I couldn???t make any of the three show me the XY scope. it was just a small dot in the middle of the screen.

The main reason was the contact spacing was too close. I like a light touch and close spacing. I spent quite a bit of time adjusting the pivot pin play using the small allen wrench provided. You want them tight enough to not allow the paddle to "wobble" but not so tight that it binds. Once those adjustments are made, set the contact spacing where you like it but wide enough for the "swing" needed to make reliable contact. You can also use a small strip of stiff paper slid between the contacts to clear out any dust or corrosion. 73, Brian, K0DTJ From rich at wc3t.us Fri Sep 22 11:22:48 2017 From: rich at wc3t.us (rich hurd WC3T) Date: Fri, 22 Sep 2017 11:22:48 -0400 Subject: [Elecraft] 630M In-Reply-To: <334afe79-f531-08a0-f841-6f5b1f8f6e80@montac.com> References: <589034430.6545377.1505994006178.ref@mail.yahoo.com> <589034430.6545377.1505994006178@mail.yahoo.com> <73DDDFE9-49B7-4550-AFE8-FAF713E7EF6D@elecraft.com> <59C513B5.9010506@roadrunner.com> <334afe79-f531-08a0-f841-6f5b1f8f6e80@montac.com> Message-ID: And some folks are doing it on our own, without waiting for the Academy. --- 72, Rich Hurd / WC3T / DMR: 3142737 PA Army MARS, Northampton County RACES, EPA-ARRL Public Information Officer for Scouting Latitude: 40.761621 Longitude: -75.288988 (40?45.68' N 75?17.33' W) Grid: *FN20is* On Fri, Sep 22, 2017 at 10:53 AM, Clay Autery wrote: > Be thou not a crotchety OM! > > There are still a bunch of folks working hard to learn code even though > it's not required.... 1+ year wait to get into the CW Academy! > > 73, > > ______________________ > Clay Autery, KY5G > (318) 518-1389 > > > On 9/22/2017 8:44 AM, Roger D Johnson wrote: > >> How ham radio has fallen.

In the past we?ve had customers turn on VFO LNK because they thought they needed to use this in conjunction with diversity mode. Since VFO LNK was rarely used intentionally, we decided to just turn it off when coming out of diversity mode, since on average it was probably turned on unnecessarily. If you use linking a lot, you might consider using a programmable function switch to turn it on/off quickly. You can even set up a macro (using K3 Utility) to do several operations at once, e.g. turn on diversity, turn on linking, set VFO B = VFO A, select an antenna, turn the preamp on, etc. Macros can be very long. 73, Wayne N6KR From jowoc1 at gmail.com Fri Sep 22 11:37:10 2017 From: jowoc1 at gmail.com (Zbigniew Tyrlik) Date: Fri, 22 Sep 2017 11:37:10 -0400 Subject: [Elecraft] Back to VFO linking.

I do this life and person and I operate it remotely, via a computer. The mode doesn't matter.? The success is still the result of personal effort.? Or would you also belittle long standing modes like RTTY and SSTV?? I also use IRLP and DMR radios which are mostly computers also, for voice! So I would say "On the contrary, ham radio has RISEN to accept modern devices, modes and uses."? There are MANY options, modes and features available to enjoy, challenge the mind, the ability to build and even struggle against atmospheric and solar conditions.? Including the use of computers to learn and discuss more about ham radio, which is presumably why you're reading this list (uh, computer to computer).

I bought a KX1 with the 80/30m option. This is not my first used rig but it is my first used kit rig. ?The rig is in good shape and appears to be well built. I haven't made a QSO with it yet but I have done some listening. ?All the menus appear to behave as they are supposed to behave. I also bought the internal ATU kit, which I built over the last couple of evenings. The ATU seems to work but I have a little more testing to do before I am sure. Here's the question(s): ? Does it make sense to run through the test and alignment procedures that one would do while building the kit?? Is there a list somewhere of tweaks and things to be aware of, especially with regard to power output, filtering or key clicks?? I have seen a random post or two about adjusting coils and the like.

The main reason was the contact spacing was too close. I like a light touch and close spacing. I spent quite a bit of time adjusting the pivot pin play using the small allen wrench provided. You want them tight enough to not allow the paddle to "wobble" but not so tight that it binds. Once those adjustments are made, set the contact spacing where you like it but wide enough for the "swing" needed to make reliable contact. You can also use a small strip of stiff paper slid between the contacts to clear out any dust or corrosion. > > 73, > Brian, K0DTJ > ______________________________________________________________ > 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 > Message delivered to rmcgraw at blomand.net > From ok1rk at seznam.cz Fri Sep 22 13:24:11 2017 From: ok1rk at seznam.cz (ok1rk at seznam.cz) Date: Fri, 22 Sep 2017 19:24:11 +0200 (CEST) Subject: [Elecraft] WTB Elecraft K3S (K3) Message-ID: <36J.16YpR.1Ew}7zmzPZD.1PnKSx@seznam.cz> I'm looking for loaded 100w Elecraft K3S with ATU and Sub RX with as many as possible CW and SSB filters in both main and sub RX Consider equally options loaded and already upgraded K3 with S/N 8801 or later I accept radio from smoker shack but must be clean and 100% electrically Shipping to EU or US address, as you prefer Payment thru PayPal or Bank transfer Contact me off-list with feature list and asking price, please: ok1rk at seznam.cz(mailto:ok1rk at seznam.cz) 73 tnx David OK1RK From edauer at law.du.edu Fri Sep 22 13:29:47 2017 From: edauer at law.du.edu (Dauer, Edward) Date: Fri, 22 Sep 2017 17:29:47 +0000 Subject: [Elecraft] Parts or Support Message-ID: <4B2D8F5E-F450-4B80-8DF7-F616A3837260@law.du.edu> I vaguely remember reading somewhere that requests for parts should now be sent to Support rather than to Parts.

Even in the manual it recommends using a band filter. It prevents high level, out of band RF from a nearby transmitter from getting into the RX port, Elecraft also mentioned that high level in-band harmonics can be an issue. This may sound strange but to protect my K3S, I found another solution. Sold by International Crystal Manufacturing, the VFA-1 is a 6 (or 2 meter) RF amplifier. Mine was build for 6 meters and was given to me years ago, before he went SK, by a fellow ham. I remember that tubes are very rugged and can withstand high RF levels and static discharge. There was an article that appeared in Popular Electronics magazine (Feb 1959) and the 1960 Electronic Experiment Handbook. Don Smith W3UZN built a box with a power supply and the VFA-1 attached. He also added an RF gain control. I decided to copy his design and try it on my K3S. Using a vertical 6m antenna and the second receiver, I monitor 6 meters on a daily basis while working the HF bands at the same time. I never experienced 6m front end overload. Because the VFA-1 has 20 DB of gain, there's no need to use the K3S preamp. I have no way to measure the noise figure but compared the K3S pre-amp, I can hear signals just as good. The tube is a 6BQ7. ----- Jack WA9FVP Sent from my home-brew I5 Core PC -- Sent from: http://elecraft.365791.n2.nabble.com/ From garyk0bc at windstream.net Sat Sep 23 01:15:23 2017 From: garyk0bc at windstream.net (Gary Harrison) Date: Sat, 23 Sep 2017 00:15:23 -0500 Subject: [Elecraft] OT: cruise ship operating Message-ID: I participated in the first QCWA Cruise Convention in 2001.?

For the last week 9/18 thru 19/23 I turn on the supply and then the K3/0 and the remote station comes up and plays as it should. Later in the day when I shut it down during the day it will not come back up and all I get is a bunch of beeps. This happens each morning. On Friday the 22nd I turned it on at 5 AM and 5 off at 5 PM. When I tried to recycle the K3/0 to turn on the remote it would not initialize and would just beep at me. This is all be done in my shack at home but via the internet thru a router. The router can see both of the RRC-1258 boxes and IP addresses which are good with the software, Microbit Software manager. I?m at a loss and can?t figure out what is causing it not to work when it works well in the morning. I can shut it down and back up in the morning but after an hour and more it will not start up again. Just beeps. Could it a cable? I had Friend stop over with his K3/0 mini head and that did not work either. I changed the K3 remote radio with another K3 radio and that did not solve the problem.

The question goes to intent. Do you intend to operate mostly, or do you intend to learn the radio inside and out? Yes, a new to the shack radio should be checked out. Doing that, can be done in a number of ways, depending on the intent. If you want to assure that it is working to specs... then a rx sens check, a spectogram sweep, power out, and tx waveform, with a monitor of current consumed, could be accomplished without disturbing the radio or risking delving into the internals. Not too time consuming either.? ? On the other hand, delving into the radio, finding out how it works, and what all goes on when signals happen, tx and rx.. then go thru the entire setup in the manual. Be aware of required test equipment to accomplish that. Takes a bit longer.. but you learn a lot too.? ?Good Luck,?

I can supply that. If you have the KXAT1 installed, pull it out and jumper between pins 1 and 3 of the 3 pin header next to the BNC jack. That connects the antenna with the KXAT1 not in place. If you have a wideband noise generator, connect it to the BNC jack - if not you can likely use an antenna - tune to a spot where there is only band noise and set the RF Gain to max clockwise and the bandwidth to a mid-point. Select 20 meters and tune CA and CB (marked 20A and 20B on the board) for a noise peak. If you cannot discern a peak, try it tuned to a moderate strength signal. Then, switch to 40 meters and peak CC (marked 40) the same way. If you have 30 meters, switch to that band and adjust the 2 trimmers on the 30 (or 30/80) meter band board for a peak (30A and 30B). Receiver alignment is done. There is not much transmit alignment to do, but if the power output is not up to par on 20 meters, try changing the turns spacing on L2 - occasionally L1 as well. These are the Low Pass Filter toroids. Yellow cores unless the KXB3080 is installed and then they are red. Work with the green windings on L1 and L2 if you have the KXB3080. You usually spread the turns a bit, but sometimes squeezing them helps. So much for the receive and transmit alignment of the base KX1. Now you can put the KAT1 back in and balance the wattmeter. Connect a good 50 ohm dummy load and set the ATU menu to CAL. Get your DMM out and set it to read a low DC voltage. Connect the negative lead to a ground - the 3/16 inch standoff on the battery connector end is my choice - use a clip lead on the meter lead. Find an insulated tuning tool that will fit the slot of the capacitor on the KXAT1 board. Put the positive meter lead on the test point next to the REFL potentiometer. Do a TUNE and adjust the trimmer capacitor for a null - at least in the low millivolt range if it does not go all the way to zero. If you have a well calibrated QRP wattmeter or other means of measuring power below 5 watts, install it between the KX1 and the dummy load. Do a TUNE and observe the power on the wattmeter an also on the KX1 display. Adjust the FWD potentiometer until they read the same. If you do not have an accurate wattmeter, observe that there are two black dots on the rotor of the potentiometer and a line on the stator. Put the two dots on either side of the line and call it good. Set the dots of the REFL potentiometer the same way unless you have a good dummy load of 25 or 100 ohms, in which case, adjust for a displayed SWR of 2.0 when that load is connected. Go to the ATU menu and set it to TUN. Close up the back cover of the KX1, you are finished inside. Now you can set the other menu parameters dealing with calibration. These are well written in the manual. BFO is first. Best done by tuning to a known frequency AM station. If your KX1 has 30 meters, use 10 MHz WWV Ignore the exact KX1 frequency display (it will be close) and tune first in LSB to a clear tone or announcement voice, and write down the frequency displayed. Then switch to USB and tune again for either the voice or the 500 or 600 Hz tone if you have perfect pitch - write down the displayed frequency. Subtract the LSB number from the USB number and record if the number is positive or negative. See page 68 of the KX1 manual for the full procedure. After the BFO Calibation, do the DDS Calibration as indicated on page 68 of the manual. You may now adjust the SIG parameters of the menu. See the menu entry on page 65 of the manual. Put the KX1 into DISPLAY with no signal input and adjust the LO parameter so there are no bars indicated. You will have to exit the menu each time to observe. Start with 1 more bars displayed and reduce the LO parameter by two until you see no bars. Sometimes you can see the lower bar flicker dimly (do not count that as a displayed bar). Then try going up one number to see if you get a bar displayed - if not, leave it alone. To set the HI parameter you will need a signal source that produces a known level signal of S-9 or S-9+20. Adjust as indicated in the menu listing for 5 bars with an S-9 signal or 6 with an S-9+20dB signal. That is it for the KX1 alignment. 73, Don W3FPR On 9/23/2017 3:38 PM, bill - K7WXW wrote: > > Intent? Good question.

I thought about trying to take a KX2 along (I?ve operated on cruise ships before), but their policy is discouraging. You can operate in the territorial waters of Canada and the U.S., and I guess maybe even Holland, but not in other territorial waters. Somehow, I thought there might be a work around on this from the Captain, but decided not to try. Well, I did bring an HT, but never used it! Holland America?s policy is sort of intriguing. It seems they don?t have a basic problem with operating, so long as you don?t obstruct things, but it also seems they are concerned about operating privileges in various countries. In other words, does the operator have the necessary reciprocal permissions under CEPT or otherwise. If that?s the case, I sort of see their point as it could be problematic for the ship. However, it also seems that one could provide the necessary documentation to show permission. I suppose that could be just too complicated for them to deal with. I also interpret their policy to NOT be prohibitive if you are on the open sea! On many cruises you are not really sure just how far out you are as you can often see land in the distance. However, there are usually several ?at sea? days, and on a trans-oceanic cruise you should be relatively safe. On the Westerdam, the TV system has a channel that constantly shows the ship?s current position, so a little navigation skill could allow you to determine your distance from any country. Even my cell phone indicated when we were ?at sea?! Hi. In essence, given their stated policy, I guess I could have done some operating. Oh Well!

Re: [Elecraft] KX1 rehab Bill, Dale gave a good answer, but did not include how to do it with the KX1. I can supply that. If you have the KXAT1 installed, pull it out and jumper between pins 1 and 3 of the 3 pin header next to the BNC jack. That connects the antenna with the KXAT1 not in place. If you have a wideband noise generator, connect it to the BNC jack - if not you can likely use an antenna - tune to a spot where there is only band noise and set the RF Gain to max clockwise and the bandwidth to a mid-point. Select 20 meters and tune CA and CB (marked 20A and 20B on the board) for a noise peak. If you cannot discern a peak, try it tuned to a moderate strength signal.

Of course I forgot the mic, but I figured I could use the built in one. The problem was that everytime I transmitted (pressing ?XMIT?) in the mode window it would switch to CW and back to USB as I released it.I thought it might be the CW in SSB setting, allowing CW to be sent while in SSB mode so I changed the menu setting in CW Weight, but it still continued to show the same in the mode window. And-never did get a Q. Of course it might have been working and they never heard me, but any ideas why that might be occurring?

This seems to have occurred with the latest Windows 10 update. Hence in this weekends CQWW RTTY contest, I could only use MMTTY with the K3s in LSB mode and not Tx Data mode.

(and spkr issue) Message-ID: I haven't seen much (if any) discussion about the latest KX2 beta firmware (MCU 2.77 / DSP 1.50, May 26, 2017). I generally don't try beta firmware unless I have a surplus device to try it on (or unless I really don't care if device I'm trying on works). Who else, outside of Elecraft employees, is running it? Have you noticed any stability issues? ----- As a side note, I thought I had somehow blown my KX2 speaker by accidentally turning off the AGC. So I just switched to earbuds and didn't mess with it for a month. Then I got brave and set out to remove the speaker from the KX2 bottom plate. After removing the bottom plate from the KX2, and before removing the speaker, I saw something shiny between the grille and the cone. It was a single whisker-strand from the 26ga copper-clad I use for my portable wire antenna. It was completing a magnetic circuit between the voicecoil spool and the chassis sheet metal. After some very patient work with tweezers, it was removed and my speaker was fixed. I recommend that Elecraft glue a layer of fine mesh fabric to the inside of the sheet metal to protect the speaker from this kind of dirt.

The next day a courier appeared at my stateroom door with a message from the Chief Radio Officer offering me a personal tour of the ship's radio room. I was let up to the bridge by a steward and Per, the Radio Officer took me into the radio room where there walls full of older HF gear which he quickly told me they don't use much anymore (mostly VHF and satellites now). He let me sit at the gear and tune around. I got some nice photos too. Huge signals from everywhere and lots of fun. Never hurts to ask, even if you've brought no gear.

It was also convenient for changing frequency and with a little very simple programming I was able to control a few features on the radio without reaching over the keyboard to the K3S. The only weird thing is the touch button programs (which is the easiest and fastest way for me to use a button as opposed to holding it down) start at macro 9 and not 1. For RTTY contesting have my K3S main and sub receiver set up in Writelog as separate radios using N6EE's instructions and works well for SO2V except for one issue. When I arrow between the two receivers, it mutes the headphone sound of the one that is not highlighted although both continuously decode in Writelog. If I move the K3S volume control even slightly the headphone audio returns however this is a pain to keep doing as I switch back and forth often during a contest. I want to hear both receivers simultaneously all of the time. Is there a setting for this?

It must have been "a long time ago" because commercial high-seas MF/HF CW traffic ended July 12, 1999. The Maritime Radio Historical Society has resurrected San Francisco Radio (KPH/KFS/KSM) on the air Saturdays under the auspices of the Golden Gate National Seashore (National Park Service) but very few ships have Morse equipment and/or operators. Safety watch is no longer kept on 500 kHz since the Global Maritime Distress and Safety System (HF SITOR/SSB, VHF-FM, and satellite radio) came into force for US-flag vessels in 1999. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From donwilh at embarqmail.com Mon Sep 25 16:42:10 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 25 Sep 2017 16:42:10 -0400 Subject: [Elecraft] [K1] Looking for KAT1 built/unbuilt for my son In-Reply-To: <1506317214688-0.post@n2.nabble.com> References: <1505114073069-0.post@n2.nabble.com> <1506317214688-0.post@n2.nabble.com> Message-ID: <6b3076f0-59b7-6819-910c-2ff0ff93ac52@embarqmail.com> Petr, Have you checked with Elecraft?

I serviced many of those consoles while they were still required and found it interesting how the economics worked. For example, the required "back up" receiver was a crystal detector for many years after "high tech" regenerative receivers were added. In the 1980's I still found a space (now blank) for the crystal detector on some ships (and that is why emergency comms always used MCW, right up to the end in 1999, in case someone was hearing the signal on a receiver without a BFO such as a crystal detector). Most of the ship's LF/MF consoles used a regenerative receiver as the required backup, once a superhet took over the main receiver position. It was fun servicing them and they were effective. As one Sparks told me when I returned his regen receiver, hooked it up and noted that local broadcast band stations near the port were causing heavy blocking, "Sonny!" He said, "If'n this tubs sink'n and someone is close enough to block my regen he's the ship I WANT to talk to!" As Archie Bunker said, "Those were the days!" 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob McGraw K4TAX Sent: Monday, September 25, 2017 11:17 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] OT - Cruise Operation My son, KD4ODR, and myself, K4TAX and our wives on a Royal Caribbean cruise many years ago had the opportunity to visit the Radio Room of the ship.

(CW only OP so no Mic to deal with so I don't know off hand what effect that has on a mic PTT, but I'm sure a quick look of the manual will answer that) Its a bit like locking your cellphone to prevent accidental number dialing. It also makes a brilliant code practice keyer in this mode and its easy to remember its set as the C for CW mode flashes, I have one of the programmable function keys set to the key input menu item too, that way its really easy to switch from hand key to paddle. I've not got round to doing the diodes on the lines yet to do that autonomously, a job for the next wet Oregon day. I've tried a number of different radios over time, and after building my K2/100 with options and a KAT100 and also my K2/10 loaded with options these are the radios for me and it's all I use and need now. Love them.

Early comparisons between SRDplay and LP-Pan were invalid due to a plastic case and cheap cables used on the SDRplay - resulting in terrible noise floor and birdies on SDRplay reception. After inserting the SDRplay in a metal case, including an inline FM broadcast filter, and replacing cheap cables, I now find the LP-Pan and SDRplay performance to be nearly identical.

My wife is diametrically opposed to taking one. Quite a few travellers to Alaska come up by cruise ship. The untold cheap alternative is taking the Alaska Ferry System. Unknown if ham radio is allowed, but I suspect so. Only US and Canadian waters are sailed. Advantage of the Ferry is that you can disembark at any stop and explore with your car as long as you wish and then catch the next Ferry to continue your trip (at no extra cost). Many Alaskans camp on the passenger deck and avoid the extra cabin charge. Ferry has a cafeteria but you are allowed to bring your own food. Cheapest rate is walk-on without a vehicle. I know that several members of the ARRL Experimental 500-KHz Group previously were ship's radio operators or land-base station ops. That results in 600m early activity being CW. FCC limited the modes we were permitted so most digital modes were not legal for us. Subsequent experimental licensee's sought permission to use several digital modes which enabled them to operate with them. We were restricted to only making 2-way contacts with members of our group and not with other licensees (definitely not with ham's). The lead person has instructed the group to cease operating now that ham radio use is permitted. I would guess you will start hearing the active members as hams as soon as they are approved by UTC. I applied the first day. But I still need to repair and rehang my inverted-L and install new synth in my K3 to be operational. When I modified my aircraft beacon (NDB) transmitter I found two xtal oscillators running at about 265-KHz separated by 400-Hz they were keyed by a MCW keyer which shifted the frequency for dots and dashes and back to original frequency for non-keyed signal thus creating 400-Hz MCW. Aircraft radios are primarily AM so could receive MCW. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From pa0pje at xs4all.nl Tue Sep 26 19:05:41 2017 From: pa0pje at xs4all.nl (Peter Eijlander (PA0PJE)) Date: Wed, 27 Sep 2017 01:05:41 +0200 Subject: [Elecraft] practicing CW on K2 without transmitting?

The amp uses the space occupied by the optional battery pack and ATU. Installing the ATU/Battery cover with those accessories makes for a nice, one box, QRP portable rig. It's not a huge issue to swap top covers, changing the K2/100 into a K2/10 or back again. Of course you don't need a heavy power supply for just 10 watts (the rated maximum output from the K2). The difference between 10 watts and 100 watts will be 10 dB (between 1 and 2 S-units at the receiving end). I've never found that to be a problem, but then I'm a QRP guy, Hi! (Note that while some get more than 10 watts from their K2, it is NOT recommended operating voice mode (SSB) at higher power levels to avoid excessive distortion.) The ATU is similar to the other Elecraft ATU's - a high-efficiency L-network with series inductance and shunt capacitance at either the input or load end. One caveat is that the miniature T1 ATU has somewhat restricted matching range on 160 and 80 meters owing to the limited space inside for the inductors required. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of KM6JMR Sent: Tuesday, September 26, 2017 3:27 PM To: elecraft at mailman.qth.net Subject: [Elecraft] K2 20 watt internal tuner I have purchased a K2/100 and was wondering if the 20 watt internal tuner cover is more or less better for field work or field day. -- From k6dgw at foothill.net Tue Sep 26 20:17:37 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Tue, 26 Sep 2017 17:17:37 -0700 Subject: [Elecraft] OT - Cruise Operation In-Reply-To: <201709262238.v8QMc6rv001733@mail47c28.carrierzone.com> References: <201709262238.v8QMc6rv001733@mail47c28.carrierzone.com> Message-ID: This uber-complexity seems to occur in many early radio equipments, often the ones purchased by the government.?

I suppose one could build exactly what you proposed using a box of knobs, switches, and meters connected to an Arduino or similar microcontroller, which would talk to the radio via the serial port. I actually did build a controller of sorts using a Arduino nano stuffed inside an old optical mouse. I used the mouse wheel and buttons and assigned them specific serial commands to send to the K3. Works pretty well for its intended purpose. An expansion of that idea could likely give you most of what you want.

There is no need to drill down into the menu for operation. The menu is normally for setup of your K3 which can be customized to your preferences before any serious operating events. I wonder what form of operating you are doing that requires constant access to the menu system. The K-Pod was not intended to alter the menu settings, it is an accessory that allows the operator (primarily contester of DXer) who uses a keyboard to reach the commonly used controls (VFO A, VFO B and RIT) without moving the hands to the radio - it is only a small distance to move the hand from the keyboard to the K-Pod. Yes, the K-Pod can initiate up to 16 K3 Macros via the buttons. What those macros may be are defined by the user. So if you are constantly using the menu system for some adjustments during normal operation, it would be wise to write macros that access that menu item(s) from a K-Pod button tap or hold. 73, Don W3FPR On 9/26/2017 9:08 PM, Byron Servies wrote: > Hi there! > > Isn't this the niche the K-Pod was supposed to fill?

When the passband edge is higher than this, FL1 is used (wide filter). (If no KXFL1 is installed, FL1 is always used.)" Indeed, when I set it to 2.9kHz the FL2 switches exactly at that point. But when I set it to 2.4kHz, the FL2 switches at 1.7kHz. I made a video clip showing that: https://youtu.be/bh3xZxrxhko. Is there any explanation?

Due to the fact the K-Pod can control the K3(s) over the production interface and the K3 can be controlled by an K3/0 mini over the UART Interface. An idea came up for improved SO2V operation if an K3/0 mini is available like in my case. If an crossed cable between production interface of K3/0 and K3(s) is used to interface the K3(s) by an K3/0 mini and the FW enables the possibility to use all "BSET" features on the K3/0 including displaying frequencies of Sub-Rx I can imagine this will improve SO2V operation dramatically. So Idea is Main Receiver and TX settings on K3 on left side of the table and K3/0 mini on the right side of the table and controlling Sub-Rx including filter etc. Just an idea which I had in mind for several days.

The most I've ever had to do is tweak VOX level, and that's VERY rare. I plug my Yamaha CM500 into the rear panel, which, by default, mutes the speaker, so I have the Speaker * Phones toggle assigned to a PF key. Since 2008, I've not found a need for the other PF key. Maybe it's VOX level. :) I LOVE the lightweight, small footprint design of the K3 -- when I replaced a pair of FT1000MPs on my very cramped operating desk, it gave me lots of space for useful accessories. I agree with Ken Kopp -- if you want a big boat, buy one. :) 73, Jim K9YC ?On 9/26/2017 11:29 PM, David Gilbert wrote: > I don't understand the need for all that menu access in the first > place for normal operating.?

The SideKar or SideKar Plus made by QRPWorks. Painless plug and play for K3 K3S KX3 and KX2. Also comes with Elecraft-level personal service from Shel, KF0UR.

SDRUno is the one they paid someone for, but before I gave up on the radio, I'd try the others.? Most (if not all) are freeware. One of the first I'd look at is Simon Brown's contribution (he was the original author of HRD when it was freeware, sold it to current owners when he got tired of answering support questions. Another issue may be that you haven't figured out how to switch in the BCB filter.

Message-ID: <3f2daabb-e231-99e7-5c70-de61c80d2383@gmail.com> For years the following setup worked well. USB Connected K3s/P3/KPA500/KAT500. CAT is COM10. Device manager says COM10 is set for 9600 baud, no parity, 8 data bits, 1 stop bit (9600,n,8,1). HRD is my main control and logging program. Everything is all hooked up and working well. Then I installed SatPC32 tracking software for future satellite work. The K3s is configured with TRN1 for my XV144 2M transverter. I turn on SatPC32's CAT switch and I can see the K3 display pausing for a split second every time SatPC32 sends a frequency update to the K3s. But the K3s is not getting the update. Checked the P3 baud rate and it? is 38,400 (remember this has not been a problem until now).? So I begin adjusting its baud rate and eventually drop to 4800 baud. Bingo! it is all working together, frequency updates to the K3s are getting there, everything is cool.... Until I get out of satellite "mode" and go back to HRD. Now HRD is not communicating with the K3s, until I set COM10 for 4800 baud as well. That actually makes good sense. The same baud rate throughout the entire connected system, but how did it work before with COM10 CAT baud rate a 9600, and the P3 running at 38,400? If you look in the K3s manual (p.63) for the RS232 menu item you will notice that it says the default is 4800b. To set it to any other value, you must get out of USB mode and use the RS232 port. At that point it is no longer COM10 but is whatever port your USB/Serial adapter is assigned by the computer. COM problems are sometimes difficult to resolve. I found an invaluable aid in Eltima software's "Serial Port Monitor".? The pro version is recommended. At 150 bucks, it is worth the money and is packed with features.

Message-ID: <20170928171654.CAVT14996.fed1rmfepo101.cox.net@fed1rmimpo210.cox.net> Hi All, I generally am pretty reticent to take issue with my ?Tucson Compadre? West, N7WS, as he most often is making very good points. However, I think he exaggerates a bit (perhaps intentionally) in attributing so much of the split operation error to K3 owners. There are a lot of us, but not even remotely close to being that many of us!! I tend to attribute that error, more than anything, to the lost art of ?mentoring?. Too many hams these days have never been effectively schooled in proper/normal operating procedures, and have no clue as to the meaning of the simple term ?UP?! Admittedly, there have been occasions when I was guilty of the sin mentioned, but only momentarily. The K3 does have the ?delta F? light to warn you, and the display does indicate ?split?. I do wish both were more obvious. Externally it looks like there might have been sufficient room to make both of those LED?s bigger and brighter. The ?split? indicator on the LCD could be bigger as well! That would be a very good enhancement. Is that possible through firmware? If there is a problem with the K3, I think it can be attributed to the trade-off between rig size and display size. I, for one, am happy with a smaller piece of gear on my desk, but I must admit that some of the display info is pretty difficult for these old eyes to see clearly. I?m inclined to agree with those who don?t feel the K3 requires an inordinate amount of menu accessing. I think Elecraft did a marvelous job of putting most needed adjustments right on the front panel. I have had a much bigger problem in this respect with other rig brands. Of course, the urge to make rigs smaller caused much of this, but even some very big rigs have this problem. The Ten-Tec Orion II is a good example. It has a big, beautiful display, and lots of panel space, but still you need to make several button pushes to make very commonly needed changes like power level and keyer speed. Both of these are instant adjustments on the K3?s front panel. Most rigs these days are fairly complex and versatile. Some are unduly complex or convoluted, but I don?t think that applies to the K3. However, if you reach for a knob or a button on any of these rigs, you better be paying attention! I think most operator errors are due to just that, and not to design issues. If something on your K3 doesn?t sound or act right, take a good, hard look at your display and panel indicators. The answer is probably right there in front of you! How many times have we seen a response like ?Are you on antenna 1 or antenna 2?? Dave W7AQK ---------------------------------------- From: Wes Stewart Have you never turned on VOX when you meant to change bands? Or set up VFO A and B to split frequencies and then accidentally (and unknowingly) written A to B when you tried to turn on Split?? Your Split indicator gives you comfort but you're still transmitting on the DX.? Probably half the, "He's split you moron" comments in pileups are directed at K3 owners. And don't even get me started about memory management.

Look specifically at the baud rate. Then set the K3 and P3, your COM ports, and other devices to the same rate. It should be the highest rate supported by your equipment and applications - so the response times are the fastest they can be and will not interfere with normal operation. There is no benefit to be gained by running at a lower rate, that will only take longer for the responses to flow between boxes. What I am saying is that if everything but one or two boxes is capable of 38,400, but you have one whose top rate is 19,200, then you should set everything to 19,200. Normally set the COM port for the highest speed it can handle and let it go at that. The application(s) will usually throttle the communications back as necessary. I don't know why the K3 defaults to 4800 baud, it is certainly capable of 38,400. 73, Don W3FPR On 9/28/2017 10:43 AM, Jim Rogers wrote: > For years the following setup worked well.

Perhaps this would encourage one to learn a bit more about the radio, as opposed to taking it out of the box, connecting a few cables and start turning knobs and pushing buttons.? Then they exclaim:?

In typical use you search for the control's indicator somewhere on the display screen in order to check its status (say AGC-S, AGC-F, etc); then search elsewhere for the control; then back to the indicator to watch it while you operate the control/button. You aren't really conscious of all the extra mental gymnastics you go through zigzagging your attention back and forth, but it's one reason why a boat anchor is more satisfying to operate-- not simply fewer controls, but the controls are self indicating or directly adjacent to meters, pilot lamps, etc. Dislocating the status indicators from the controls also makes learning to operate the rig more difficult initially and probably leads to recurring errors like SPLIT. 73, Drew AF2Z On 09/28/17 13:16, dyarnes wrote: > Hi All, > > I generally am pretty reticent to take issue with my ?Tucson Compadre?

I think Elecraft did a marvelous job of putting most needed adjustments right on the front panel. I have had a much bigger problem in this respect with other rig brands. Of course, the urge to make rigs smaller caused much of this, but even some very big rigs have this problem. The Ten-Tec Orion II is a good example. It has a big, beautiful display, and lots of panel space, but still you need to make several button pushes to make very commonly needed changes like power level and keyer speed. Both of these are instant adjustments on the K3?s front panel. > > Most rigs these days are fairly complex and versatile. Some are unduly complex or convoluted, but I don?t think that applies to the K3. However, if you reach for a knob or a button on any of these rigs, you better be paying attention! I think most operator errors are due to just that, and not to design issues. If something on your K3 doesn?t sound or act right, take a good, hard look at your display and panel indicators.

Gee -- every time I buy (or otherwise need to use) a new product, I RTFM. As a result, I've never had any problem with knowing how the K3 works and getting it to do what I want it to do. And I never bother with FAQs, which are written either for users who have never RTFM, or who don't know much about the functions for which the product is designed, or for products for which the manual is so bad that everyone has questions. :) I'll be 76 years old in a few weeks, and I've been a ham for 62 years. I've owned and/or used dozens of radios over the years. I find the design and user interface of the K3 series of radios VERY well thought out and both the front panel controls and the display quite logical. But then, I RTFM. Another thing -- a K3 is pretty easy to pack as a carry-on -- W0YK carries two of them in the passenger compartment for DX and contest trips!

Is the setup for your data mode application software set up the same on the old computer and the new? Does the red TX LED light? If so, the PTT signal from the application is putting the K3 into transmit. You must set the computer soundcard audio for 4 bars solid with the 5th bar flickering. Do you have that set? How is the computer application sending PTT to the K3? Via CAT command or via the RS-232 connection? If the RS-232 connection, is it using DTR or RTS? Is the K3 PTT-KEY menu set to the same signal for PTT? In other words, too many variables. Give us your complete setup information, and maybe we can help. Just saying "it doesn't work" can leave a large batch of possibilities. Since you know the K3 worked before (with the old computer), then the problem is with your application setup on the new computer. 73, Don W3FPR On 9/29/2017 11:31 AM, John Green wrote: > I have successfully made JT65 contacts with a prior HP laptop using it's sound card and a K3 with the new K3S synthesizer.

At that time I also changed the scrolling sign on banner. Now when I power up the K3, I'm getting text showing up before the reset banner. For example if my new banner is my call, W3SB, before it scrolls there is text, let's say "XYZ_" ahead of it. Since "XYZ" is a piece of equipment I used to have, I know that I set "XYZ" at some point, but for the life of me I don't know how. Is there some other way that the sign on banner text can be set?

It?s true that Wayne Burdick is just about as good as they come in this regard, but he has long had some serious competition. Steve Weber and Dave Benson are just a couple. Wayne took it to a new level when he joined forces with Eric to form Elecraft. I?m not convinced there aren?t a lot of great ideas along this line that are running through Wayne?s head. He just has a lot on his plate right now. Besides, the KX2 isn?t all that old, and it has Wayne?s fingerprints all over it! As for Hans Summer, who created the QCX rigs, well, he?s been around a good while too! The problem is that a lot of us on this side of the pond, and maybe even other places outside the U.K., haven?t been all that aware of what Hans has been doing for a long time! Hans was elected into the ARCI Hall of Fame back in 2009, and that recognition was probably late in coming! Members of GQRP have probably been aware of Hans and his talents for years. If you have only been following the various Elecraft reflectors, you probably haven?t heard much about him. It?s sort of like TV news channels?if you don?t flip around a bit, you don?t get the big picture! I also think Hans has a ?day job? which keeps him otherwise occupied. Right now I guess Hans is ?The Man of the Hour? with his QCX kits. Over 1,000 of them have been sold in just a few weeks! More are in process! Amazing! We are so fortunate to have stuff like this made available to us. It?s no wonder this hobby keeps on giving!

That is in contrast with the work Dave Benson did for the hobby. I understand that they (or at least those who kit them) are individuals and are reluctant to take a longer term risk of investment in boards and the parts that go on them - things that may take years to sell and recoup the investment. Let's face it, those folks take delight in experimenting and coming up with new designs, but have no desire to turn those designs into a long lasting product line. They have no factory behind then to take over the chores after the initial fervor has died down. 73, Don W3FPR On 9/29/2017 2:08 PM, dyarnes wrote: > Hi All, > > I also have a couple of the QCX kits here waiting to be assembled.

If you read the top right column of page 19 in the K3 manual (or page 21 of the K3S manual, you will see that AUX IO pin7 (XVTR ON) could also be used, but if you use TX INH or plan to possibily do so in the future, that same pin is dedicated to TX INH.

Amateurs are permitted to operate on five specific frequency channels, each having an effective bandwidth of 2.8 kHz. *Table 1:* Channel 1: 5330.5 kHz Channel 2: 5346.5 kHz Channel 3: 5357.0 kHz Channel 4: 5371.5 kHz Channel 5: 5403.5 kHz These frequencies are available for use by stations having a control operator holding a General, Advanced or Amateur Extra class license. It is important to note that the frequencies shown above _are suppressed carrier frequencies_ ? the frequencies that appear in your transceiver?s tuning display when your transceiver is in the USB mode. Amateurs may transmit with an effective radiated power of 100 W or less, relative to a half-wave dipole. If you?re using a commercial directional antenna, FCC Rules require you to keep a copy of the manufacturer?s gain specifications in your station records. If you built the directional antenna yourself, you must calculate the gain and keep the results in your station records. When using a directional antenna, you must take your antenna gain into account when setting your RF output power. For example, if your antenna offers 3 dB gain, your maximum legal output power on 60 meters should be no more than 50 W (50 W plus 3 dB gain equals 100 W Effective Radiated Power). *Upper Sideband Operation* Upper Sideband operation on 60 meters is simple. Just tune your transceiver to one of the channel frequencies shown in Table 1 and operate, being careful you do not over modulate and create ?splatter? that would fall outside the 2.8 kHz channel bandwidths. If your transceiver allows you to adjust your maximum SSB transmit bandwidth, setting it to 2.4 kHz should keep you well within the legal limit. *CW Operation* CW operation must take place at the _center of your chosen channel_. This means that your transmitting frequency must be 1.5 kHz above the suppressed carrier frequency as specified in the Report and Order (see Table 1). Operating at strict channel-center frequencies may come as a disappointment to many, but cooperating with the NTIA is key to expanded privileges in the future. The channel center frequencies are: Channel 1: 5332.0 kHz Channel 2: 5348.0 kHz Channel 3: 5358.5 kHz Channel 4: 5373.0 kHz Channel 5: 5405.0 kHz Consult your transceiver manual. Some transceivers transmit CW at the exact frequencies shown on their displays, but others offset the actual transmission frequency by a certain amount (for example, 600 Hz). If your manual is not clear on this point, contact the manufacturer. If you have access to a frequency counter, this is an excellent tool for ensuring that your CW signal is on the channel center frequency. *Digital Operation* Our expanded privileges on 60 meters were the result of collaboration between the FCC and the NTIA ? the National Telecommunications and Information Administration, the agency that manages and coordinates telecommunications activities among US government departments, the primary users of the band. The NTIA expressed concern about possible interference and requested that amateurs limit digital operating to PSK31 and PACTOR III only. It is certainly possible to interpret the FCC Report and Order somewhat broadly as it concerns digital operating on the band, but be careful not to read too much into the text.Therefore, as a practical matter it appears that any J2D data emission is to be permitted up to a bandwidth of 2.8 kHz, provided that care is exercised to limit the length of transmissions With an eye to the potential for expanded 60 meter privileges in the future, the ARRL believes it is critical to cooperate fully with the NTIA. Therefore, the ARRL asks all amateurs to *_restrict 60-meter digital operations to PSK31 or PACTOR III._**_ _* With PSK31 you must operate on the following channel center frequencies: Channel 1: 5332.0 kHz Channel 2: 5348.0 kHz Channel 3: 5358.5 kHz Channel 4: 5373.0 kHz Channel 5: 5405.0 kHz The easiest way to achieve this is to place your transceiver in the USB mode and tune to one of the suppressed carrier channel frequencies shown in Table 1. With your PSK31 software display configured to indicate audio frequencies, click your mouse cursor at the 1500 Hz mark (see below). With your radio in the USB mode, this marker indicates the center of the channel and it is the frequency on which you should be transmitting. PACTOR III operation on 60 meters is straightforward. With your transceiver in the USB mode, tune to one of the suppressed carrier channel frequencies shown in Table 1. Note that only live keyboard-to-keyboard operation of PACTOR III is allowed. Unattended automatic operation is not permitted. 73 Bob, K4TAX From k6dgw at foothill.net Fri Sep 29 21:41:22 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 29 Sep 2017 18:41:22 -0700 Subject: [Elecraft] 60 meters and the K3S In-Reply-To: <1FC8BF91-04CB-4925-94F5-E7F1FF96B62C@widomaker.com> References: <002201d33960$6c8670b0$45935210$@comcast.net> <1FC8BF91-04CB-4925-94F5-E7F1FF96B62C@widomaker.com> Message-ID: <2732fce2-11b8-cfbe-5dcb-21aa6e721223@foothill.net> Bill, while the original post was about the 60 m channels, the K3 Memory Editor works for all frequencies for all bands.?

I was never able to tame the large 'spike' at the IF frequency. I then switched to an external USB sound card (Xonar U7) which was better, but still not great. Then i got a SDRPlay RSP1, which makes a pretty decent panadapter, but was not really happy with any of the SDR software that i tried (and I tried several). Finally, I built a P3 kit. The P3 requires far less fiddling around that any of the other things I used before. I was concerned about the small display, but found it perfectly adequate for me. Your mileage may vary. I did hook up the RSP1 to the IF Out of the P3 to try it with Win4K3, with the idea of getting 'point and click QSY' with the mouse. That worked, but I found that I didn't really use it, so I'm back to just using the P3. I guess I like the fact that it just works - no need to launch software, mess with configuration of SDR options, fiddle with calibration to get the frequency on the screen aligned with the frequency on the K3, etc. I have not tried SpectraVue as suggested by N7WS...perhaps i should. I found HDSDR and even Rocky just too much bother just to get a useful panadapter. I do not have the SVGA option, so cannot comment on that. My only gripe with the P3 is the way it implements the QSY function. You need to move the marker with that tiny knob, then push the knob to make the VFO jump to the marker. I often wind up bumping the rotational position of the knob when pushing it in, and/or pushing the whole unit backwards on the desk. So, I seldom use that function. Instead, I move the P3 VFOB indicator to the signal of interest with the VFOB knob on the K3, and hit A/B on the radio to jump there. If I could manipulate the markers and the 'QSY to marker' function with a KPod, I'd consider buying one.

I cannot speak for Steve Weber, but I do *NOT* produce kits only for a limited amount of time! I *DO* have a desire to turn kits like the QCX http://qrp-labs.com/qcx into a long-lasting product line.

The QRSS/WSPR transmitter kit product line has been running now since my Dayton FDIM talk in 2010; the current Ultimate3/3S incarnation http://qrp-labs.com/ultimate3 has been in continuous production since 2013 - selling well over 4,000 units to date. Of course, it IS correct that I love experimenting and coming up with new designs... as I am sure Wayne does too... but this is still a serious business! 73 Hans G0UPL http://qrp-labs.com Don wrote... While Steve Weber and Hans Summer do really good work and well thought out designs, I see only one problem with the stuff they do - the kits are available only for a limited time. That is in contrast with the work Dave Benson did for the hobby. I understand that they (or at least those who kit them) are individuals and are reluctant to take a longer term risk of investment in boards and the parts that go on them - things that may take years to sell and recoup the investment. Let's face it, those folks take delight in experimenting and coming up with new designs, but have no desire to turn those designs into a long lasting product line. They have no factory behind then to take over the chores after the initial fervor has died down.

" Sorry Lyle:-) > For measurement purposes I love the SDR-IQ and SpectraVue; but operating and contesting are a different application. When operating, I focus almost entirely on the waterfall display because that presents a time-history of everything that has been happening for the past several minutes across the entire displayed bandwidth. The waterfall is a huge information resource. On an empty band the waterfall shows instantly where new stations are popping up, while on a full band it shows if there are any free channels and how long they have been free. Meanwhile the color shading shows which signals are strongest, and instantly identifies which ones are spreading more than they should. Compared with that wealth of operating information from the waterfall, I find the spectrum-analyzer display is almost worthless (but remember we're talking about here operating, as distinct from making measurements). To extract the maximum possible information from the waterfall, I normally maximize the vertical size, aiming for a time-span of 3-5 minutes. The spectrum analyzer display is always minimized (and if the display software allows, I get rid of it entirely). When operating, the waterfall display is front-and-center on a wide-screen monitor. For most modes, only the small log input windows need to share display space at the bottom of the screen, and all other operating windows are displayed on a second monitor. RTTY is the only exception, where multiple decoder windows take over the center screen and the waterfall has to take second place. I currently have two K3s with different types of spectrum/waterfall displays. The HF/50MHz setup uses a P3, which of course has the advantage of very tight integration with the K3. However, I do find that the P3 requires the SVGA adapter to display the wealth of detail that the waterfall has to offer. The P3's own screen is bright and clear, but is simply too small (in terms of pixels). And unfortunately the P3/SVGA has a number of disadvantages compared with the SDR-PC competition. There is an issue with the P3SVGA's limited color palette which tends to suppress weaker signals. The P3 also lacks any method to QSY *quickly* across a wide frequency span to grab fleeting DX opportunities on a nearly empty band. The other K3 is used with external VHF/UHF transverters, and for this application I decided not to buy another P3 but to play the market of separate SDRs and PC software. The SDR is attached to the K3 at the transverter IF frequency of 28MHz, which gives much better display sensitivity than the 8.2MHz IF. For VHF/UHF contesting and DXing it is essential to display everything that lives and breathes across the entire "contest sub-band", which in Europe extends over at least 250kHz. Important multipliers tend to lurk at both the top and bottom ends of that range, so 200kHz is not acceptable. Several good SDRs with 190-200kHz maximum bandwidths, including the SDR-IQ and the P3, had to be ruled out for that reason. After some searching I found that the SDRplay RSP-1 delivered the best combination of dynamic range, available spectrum width (far more than I need) and value for money. Again after some experimentation, I settled on the HDSDR software, which gives a very readable and sensitive display on the large screen and provides most of the facilities of a second receiver. Integration with the K3 was not easy to configure, but after some work it now has all the frequency agility that is so lacking in the P3. The SDR frequency is linked to VFO B on the K3, and can be tuned using any combination of the VFO B knob, point-and-click on the display (rolling the mouse wheel for fine tuning), clicking on the bandmap in N1MM+, or typing frequencies directly into the callsign window. Thanks to HDSDR's built-in Omnirig interface, any one of those frequency inputs will automatically update all the others. As a receiver, the SDR is more than adequate for searching the band and finding new stations to work, interleaved with calling CQ on the K3. If a new station appears on the SDR, its frequency is already pre-loaded into VFO B on the K3 so one tap of VFO A/B will swap that signal into the K3, ready to call at the right moment. I do share Wes's dislike of "video-game" displays. I hate how modern software so often arrives with every possible function activated at once... but if you take the time to strip away the dross, the end result can be quite lean and functional. Maximizing the waterfall display and hiding the controls tends to remove most of those annoyances, and the advantages of a really good panadapter have persuaded me to live with the rest. 73 from Ian GM3SEK From donwilh at embarqmail.com Sat Sep 30 07:32:24 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 30 Sep 2017 07:32:24 -0400 Subject: [Elecraft] OT: The times they are a changin In-Reply-To: References: Message-ID: <0ff6496b-e580-7023-6625-0be5d184da37@embarqmail.com> Hans, Thank you for that correction.

I have a K2, 6000+ serial number, that I'm trying to get working correctly. Unknown history. A quick test showed the filters were not properly adjusted (could hear both sidebands of carrier on some bands). I thought it would be best to do a top-down alignment. I adjusted the 4 MHz oscillator, verified the PLL reference oscillator range (12.43 kHz), VCO test and VCO alignment. No problems up to that point. I'm having an issue at the BFO test. The BFO high frequency is 4916.04 kHz and the low frequency is 4913.82 kHz. That's a difference of 2.19 kHz, well below the 3.6 kHz stated minimum. I verified the crystals at X3 and X4 were the correct type, along with the values of D37, D38, C173 and C174. I didn't see any PCB trace damage in the area. I reflowed the solder on those pins but didn't see a significant change in the BFO frequency range. I checked the VBFO control voltage and had 7.81 V at the high BFO frequency down to 0.00 V at the low BFO frequency. Any advice on how to move forward? Thanks and 73, Mike M.

The toroid wires are very fine and sometimes are not visible to the naked eye, so use magnification to examine them. When re-soldering, use a pointed tool to bring the fine toroid wires down onto the solder pad instead of further up on the securing resistor lead. For adjusting the 4 MHz Reference Oscillator (that has nothing to do with the BFO range), refer to the K2 Dial Calibration article on my website www.w3fpr.com for the most accurate method of adjusting the Reference Oscillator. Be aware that the 4 MHz Reference oscillator can drift in normal operation, so soon after adjusting it, run CAL PLL and CAL FIL while it is still "on frequency". That oscillator is not used in operation for the K2 frequency display. In other words, simply adjusting the 4 MHz Reference does nothing for normal operation. 73, Don W3FPR On 9/30/2017 9:35 AM, Mike Maiorana wrote: > Hello all.

The waterfall is a huge information resource.

The spectrum analyzer display is always minimized (and if the display software allows, I get rid of it entirely). When operating, the waterfall display is front-and-center on a wide-screen monitor. For most modes, only the small log input windows need to share display space at the bottom of the screen, and all other operating windows are displayed on a second monitor.

The HF/50MHz setup uses a P3, which of course has the advantage of very tight integration with the K3. However, I do find that the P3 requires the SVGA adapter to display the wealth of detail that the waterfall has to offer. The P3's own screen is bright and clear, but is simply too small (in terms of pixels). And unfortunately the P3/SVGA has a number of disadvantages compared with the SDR-PC competition. There is an issue with the P3SVGA's limited color palette which tends to suppress weaker signals. The P3 also lacks any method to QSY *quickly* across a wide frequency span to grab fleeting DX opportunities on a nearly empty band. > > The other K3 is used with external VHF/UHF transverters, and for this application I decided not to buy another P3 but to play the market of separate SDRs and PC software. > > The SDR is attached to the K3 at the transverter IF frequency of 28MHz, which gives much better display sensitivity than the 8.2MHz IF. For VHF/UHF contesting and DXing it is essential to display everything that lives and breathes across the entire "contest sub-band", which in Europe extends over at least 250kHz. Important multipliers tend to lurk at both the top and bottom ends of that range, so 200kHz is not acceptable. Several good SDRs with 190-200kHz maximum bandwidths, including the SDR-IQ and the P3, had to be ruled out for that reason. After some searching I found that the SDRplay RSP-1 delivered the best combination of dynamic range, available spectrum width (far more than I need) and value for money. > > Again after some experimentation, I settled on the HDSDR software, which gives a very readable and sensitive display on the large screen and provides most of the facilities of a second receiver. Integration with the K3 was not easy to configure, but after some work it now has all the frequency agility that is so lacking in the P3. The SDR frequency is linked to VFO B on the K3, and can be tuned using any combination of the VFO B knob, point-and-click on the display (rolling the mouse wheel for fine tuning), clicking on the bandmap in N1MM+, or typing frequencies directly into the callsign window. Thanks to HDSDR's built-in Omnirig interface, any one of those frequency inputs will automatically update all the others. As a receiver, the SDR is more than adequate for searching the band and finding new stations to work, interleaved with calling CQ on the K3.

Excellent analysis, Ian. I agree completely. FWIW, Elecraft is very much in touch with the contesting world -- K6XX works there, and guys like N6TV had great input into the SVGA. Both are world class contesters.

A hybrid splitter is used to maximize the isolation between the SDR and the K3's receiver. This method is used in preference to the internal 8.2MHz IF output of the K3 because the transverter output port can deliver a higher signal/noise ratio to the input of the SDR, which improves its ability to display extremely weak VHF/UHF signals. 73 from Ian GM3SEK >-----Original Message----- >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of Dave Fugleberg >Sent: 30 September 2017 14:15 >To: Ian White; Elecraft at mailman.qth.net >Subject: Re: [Elecraft] SDRPlay as panadapter > >You raise some great points, Ian.

It's the "Real Radio Man" arrogance that kicks in with a new radio. As for the button/knobs vs. menu's argument, what is the difference between a button or knob on the face of the rig that gets adjusted once and never touched again and a making the same change with a menu? There is no difference in functionality. Maybe it's that the higher button and knob count increases the machismo? "I, a Real Radio Man, can operate this radio that looks like a 707 cockpit" (caveman grunting and chest thumping ensues), and it will really impress the neighbors. Possibly people don't know how to set the rig up and have to fiddle with it continuously? Knobs and buttons do make fiddling easier. They do not change the fact that you do not know the radio or how to set it up. The days of the 70lb Samsonite sized rig with 100+ knobs and buttons (TS-990S) are over Real Radio Men.

If you used your DMM while it was in-circuit, then you have an open L33.? The BFO would oscillate, but the range would be restricted as yours is or more narrow. First thing, check capacitors C173 and C174 to be certain you have the correct values installed.? Those blue capacitors with the yellow printing on them are difficult to read, so use a magnifier and lots of light. Then check D37 and D38 to be certain they are oriented correctly - the slightly angled side is the "rounded" side. Make certain RP6 is well soldered - reflow with a hot iron (750 degF) and apply a bit of extra solder - you really one need the flux.? The iron dwell time should be about 3 seconds, but watch for the solder to flow out onto both the solder pad and the component lead to assure good soldering - up to 5 seconds dwell will not hurt anything. Then when doing the BFO Hi and BFO LO frequency checks make sure RP6 pin 7 goes to quite near 5 volts and also quite near zero volts. The above are the easiest items to check. Keep in mind that the resistor which holds L33 is really an insulator, it serves no electrical function. You are correct that a bad BFO crystal could cause the problem, but to change them (change them as a matched pair), you have to lift L33.? Not too bad is you are careful, leave the leads connected to the resistor leads, heat the solder pad and pull the resistor lead out - repeat for the other side and lift L33 and the resistor off as an assembly. So try the easy stuff first, and if that does not cure it, contact Elecraft Support and request a pair of BFO crystals and a new L33 and 5.1 meg resistor to replace them. 73, Don W3FPR On 9/30/2017 5:40 PM, Mike Maiorana wrote: > Thanks Don. > I triple-checked the inductor wires and they are well soldered to the > pads.

I presume there is a tradeoff between real estate being used by the monitors versus preferred viewing size for seeing what the P3 can provide. Exactly right. There's also the issue of finding monitors that will run on 12-14VDC, so that they can be powered from clean power supplies. :)? And you want a monitor with a VESA mount. Several years ago, Costco was selling a 24-in Samsung that runs on a nominal 14VDC, and that is reasonably quiet if its cables are well choked. 14VDC models have been disappearing from Samsung's product line, but there may still be some around. Also, not all Samsung monitors are RF quiet -- W4UAT gave me one with touch controls that turned flips in the presence of RF and also was quite noisy. He couldn't use it in his station because he was on a small lot with antennas very close to the shack. I tried using it for a while, but eventually gave it away. 73, Jim K9YC From donwilh at embarqmail.com Sat Sep 30 20:30:24 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 30 Sep 2017 20:30:24 -0400 Subject: [Elecraft] KX3: slow build to full power on 15 meters only In-Reply-To: References: Message-ID: <5aa97d78-ac24-47d6-197f-d2c1cf90e6f4@embarqmail.com> Bob, It sounds like your KX3 is "power hunting". The KX3 (and other Elecraft transceivers) control power differently than any other amateur transceiver, so you must ignore the common internet (and many data mode instructions) in how to set up the KX3 for data modes. Do you have sufficient audio into the KX3 on 15 meters? You should drive the audio enough to produce 4 bars with the 5th bar flickering on the ALC meter. Since the RF Gain can vary from band to band, you really should check the level on each band. Check out the document on my website www.w3fpr.com. Scroll down to the bottom of the left column for the link to the page. Ignore the internet advice and set your KX3 properly for audio, and then control the power with the power knob. 73, Don W3FPR Refer to the document on my wesite On 9/30/2017 7:48 PM, R Edward wrote: > I have an odd issue that is only happening on 15 meters, and I notice it most in digital modes because they are 100% duty cycle.

I'm hacking on a monitor like the two I'm using to figure out where to bypass the internal power supply and tap in to provide clean DC. At this point, I'm simply trying to minimize the number of voltages required rather than get everything to the near 12-14 vdc...

I presume there is a tradeoff between real estate being used by the monitors versus preferred viewing size for seeing what the P3 can provide. Exactly right. There's also the issue of finding monitors that will run on 12-14VDC, so that they can be powered from clean power supplies. :)?

I think I've found the problem. After doing the visual checks you suggested I wanted to try and isolate the crystals to see if the problem was there. I left L33 alone and carefully removed the BFO crystal that was accessible without removing the inductor. Now CAL FCTR showed the BFO frequency as 00000. Interesting. I then removed L33 and the second BFO crystal. Using a simple crystal tester/oscillator I have showed the second crystal (the one under L33) did not oscillate. The other crystal seemed to oscillate fine. So, it looks like an order for a pair of BFO crystals should get me back in business, or at least let me continue the alignment. Hopefully this was the only problem. Thanks again Don for your expert advice. I'll follow up when I get the replacement parts. Best regards and 73 Mike M.
