From frantz at pwpconsult.com Sun Jul 1 00:24:26 2018 From: frantz at pwpconsult.com (Bill Frantz) Date: Sat, 30 Jun 2018 21:24:26 -0700 Subject: [Elecraft] Filters In-Reply-To: <7B50C45D-527F-4588-A377-198C124715B1@yahoo.com> Message-ID: Mine moves in .10 increments, but it seems to like the numbers that end in 5. e.g. .350. I wouldn't worry too much about it. set the low end to .3 or to .4, depending on conditions and the voice you're listening to and call it good. The whole purpose of the knobs is to let you adjust the bandwidth to match conditions. 73 Bill AE6JV On 6/30/18 at 8:44 PM, elecraft at mailman.qth.net (Michael Gillen via Elecraft) wrote: >Hmmm when I try that I get Shif=.05 however and when I turn >VFO-A it says N/A and it still moves in .10 increments? > > >>On Jun 30, 2018, at 7:55 PM, Jack Brindle wrote: >> >>PB CTRL should do what you want.

The manual clearly states that PB CTRL only affects CW and Data modes, and shifts the increment between 0.05 and .01 KHz. It appears to be fixed at .1 KHz for SSB for both low and hi cut.

The variety of shades of green around the mountain is astounding this week.? All the trees have their new growth of needles, many species of berry bushes are blooming or forming berries, the ferns are almost done unrolling, and the leaves of the undergrowth have all formed.? The hummingbird feeder needs to be refilled every three days.? They seem to be in constant motion; feeding their young and defending territories.? Just one species is present again this year.? The chilly weather has kept the Anna's hummingbird away the last two years.? It would be nice to have some warm weather again, I had to start a fire a few days back to drive the chill out of the house. ?? The sun is spotless and mostly quiescent.? While it's not providing a lot of new ions it is not making much noise either. With less noise I can hear better but even my very low noise floor is not enough to make up for the lack of signals bouncing once or twice on the ionosphere.? By this time next year I hope to see an improvement.? Patience can get boring. Please join us tomorrow on: 14050 kHz at 2200z Sunday (3 PM PDT Sunday) ? 7045 kHz at 0000z Monday (5 PM PDT Sunday) 73, Kevin.

Temporarily switch to Shift/Width and set Shift to a value that, when divided by two results in a value of X.X5. Now switch back to Hi/Lo ... those value will end in X.X5 and step in increments of X.10. 73, ...

The LowCut and HiCut controls are like the Bass and Treble controls on a car AM/FM radio. Think what would happen if your radio's Bass control were reduced by 100 Hz instead of 50 Hz - the difference is insignificant. Oh yes, the Bass and treble controls on that AM/FM radio are not calibrated for precise frequencies like the K3 HiCut/LoCut controls are, so we "use our ears" to determine what is best. We should do the same for the K3/K3S/KX3/KX2. There is no communications effectiveness for frequencies below 300 or 400 Hz (0.30 to 0.40) on the low cut side, and there is little voice recognition in that range. The effective range for voice recognition begins at about 500 Hz, and extends to about 2600 Hz. That is for recognizing the characteristics of a particular voice pattern we are familiar with. For communications effectiveness, we can reduce the listening range to 500 Hz to 1700 Hz and still communicate with clarity. 73, Don W3FPR On 7/1/2018 10:20 AM, Clay Autery wrote: > I don't have "perfect pitch", but do have extensive music experience if > that matters.... > > Single tone, single voice, or an orchestra....? 50Hz off freq. is enough > to make me want to drill holes in my head.?

Yeah I know, the grid square should be sufficient, but years ago, there was a 6M beacon in the Washington DC area signing a KL7 call. This was before the proliferation of out-of-area call signs were common. Talk about shaking up the troops when THAT one hit the airwaves! And yes, when I moved to Virginia I held a secondary location call, WA4LJQ (could it get much longer for CW?), with k3ICH still assigned to my parents house in Forestville MD where I was 1st licensed as KN3ICH. I was very lucky to have been able to hang onto my original call, as many didn't have the luxury and had to loose their old calls when they applied for the new station location. 73, Charlie k3ICH/4 -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Wayne Burdick Sent: Sunday, July 01, 2018 10:33 AM To: Elecraft Reflector Subject: [Elecraft] Proposed: more 6 meter CW beacons When 6 meters opens up, a few low-power CW beacons I?ve never heard always pop up in the low end of the band.

If one is depending on only the F1 formant, then a cutoff of about 1000 hertz is appropriate. Another rule that applies is the 450,000 (or 500,000) rule. Multiply the highest frequency by the lowest frequency and the product should be one of those two numbers for a balanced response. So, if the upper cutoff is 1 KHz, then the lowest would be 500 hertz. Such a response is slicing the F1 formant which is typically 1 KHz wide.

The effective range for voice recognition begins at about 500 Hz, and extends to about 2600 Hz. That is for recognizing the characteristics of a particular voice pattern we are familiar with. For communications effectiveness, we can reduce the listening range to 500 Hz to 1700 Hz and still communicate with clarity. > > 73, > Don W3FPR > >> On 7/1/2018 10:20 AM, Clay Autery wrote: >> I don't have "perfect pitch", but do have extensive music experience if that matters.... >> Single tone, single voice, or an orchestra.... 50Hz off freq. is enough to make me want to drill holes in my head.

Message-ID: I dragged my HP8640B out of the "lab" (basement) to the second floor shack to do some antenna testing about a week ago. Before dragging this 50 lb instrument back down two flights of stairs I decided to do a quick MDS measurement on my K2 and got some results I'm a little concerned about. Yesterday I did an informal test. K2 set for cw, 1.5 KHz bandwidth, 14.05 MHz, AGC on, preamp off. Attached siggen, tuned the K2 to 550 Hz tone and cranked down the siggen amplitude until the signal and noise were about equal, "by ear". Siggen output was -130 dBm. This was enough to cause me to look further. Today I took some numbers. Same setup, but with a Fluke dvm instead of ears and the siggen phase locked . Started at -90 dBm drive and tuned the K2 to peak voltage reading. Then made the following measurements: _Sigen (dBm)????? Meter(V)_ -90????????????? ? ? ? ? .38 -100 ? ? ? ? ? ? ? ? ?? .15 -110 ? ? ? ? ? ? ? ? ?? .050 -120 ? ? ? ? ? ? ? ? ?? .017 -130 ? ? ? ? ? ? ? ? ?? .011 (off) ? ? ? ? ? ? ? ? ? ? .010 Then did a rough voltage-ratio-to-dB "calibration" as follows: Set siggen to -100 dBm & measured the same .15V ob the K2, then ran the siggen output to 103 dBm and measured .204V. So 3dB signal difference is a voltage ratio of 1.36. Finally measured MDS driving the K2 until the measured signal voltage was (.011 * 1.36 = .015 V).? I got this value at a drive level of -123 dBm. Tried a second set of measurements with the preamp on using the same technique and got the same MDS of -123 dBm. Tried a third set of measurements with preamp off? and AGC off and got a slightly worse MDS of -121. Now I know there are flaws with this measurement, especially in measuring a signal near the noise. But I know the provenance of the siggen, use it all the time and get good measurements from it. I trust it. If it was a matter of 2 or 3 dB I wouldn't be writing to the list, but this is 6-11 dB worse than the 2 numbers on Sherwoods site (-129 and -135). FYI, another informal "measurement" I made was on? 6M with the XV50. A signal was easily audible over the noise with the siggen set at -140 dBm drive! On air results are equivocal: yesterday afternoon I couldn't hear my friend Joe N2CX 145 mi away who was qrp portable on 20M (something I've done multiple time in the past), but I had 3? consecutive easy q's to eastern EU last night on 30M... On the K2, gain could be missing or noise could be high anywhere: front end, I.F, audio stages. What do you think.? Could / should I send it away for work. It'd have to go somewhere with better instruments, since the K2 isn't exactly "broken". Or should I don't worry be happy? 73, --Lenny W2BVH ps -FYI this is K2 1520, I built in 1999 & been in use here ever since.

Also for voice modes, I?ve compiled some ideas from this list (along with one of my own) for cleaner mic bias and for TX EQ and compression setup. https://observer.wunderwood.org/2015/08/16/yamaha-cm500-headset-with-ptt-on-elecraft-kx3/ https://observer.wunderwood.org/2015/09/09/transmit-audio-and-compression-with-the-elecraft-kx3/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jul 1, 2018, at 11:43 AM, Wayne Burdick wrote: > > Hi Joe, > > #1 suggestion: read the manual.

You can check and uncheck the antennas needed for each band. I don't have my station set up at the moment but something like this might work: Select Band 17 and 12, check Ant 1 and click apply Select Band 20, 15, 10 and 6, check Ant 2 and click apply Select Band 160, 80, 60, 40, and 30, check Ant 3 and click apply. Tuner mode will be selected when you are on a band and you select the mode. Note that you should train the tuner on 160, 80, 60, 40 and 30 and then run Manual mode, not auto mode.

If you "train" the KAT500 with your resonant antennas, it should discover and store the "bypassed" ATU setting. Even though the MODE LED says "MAN", the ATU settings stored are the "bypassed" settings. You can see this in the KAT500 Operate page - Try "ATU TUNE" for your resonant antenna. It should discover that the best setting for this antenna is "bypassed". On some bands (my 20 meter beam), I end up with "bypassed" at the CW end of the band, but up in the phone band the ATU provides a little help. But I don't want to have to manually choose between BYP and MAN for different band segments. The ATU training session provides matching reactances when needed, and ATU BYP when not needed. The ATU stays in mode MAN. The same concept applies if you choose an antenna that never needs help. Erase memories on that band/antenna combination, do an ATU TUNE at three point s in the band, then you'll get that same setting in intermediate frequencies. You can choose with the "BYPASS SWR THRESHOLD" what SWR the ATU should use when deciding whether to use "bypassed" or apply reactances. Some really want to see 1:1 when possible, others think that 1.2 is better bypassed than with any real or perceived ATU losses. The ATU relay settings with the ATU BYP and when in mode MAN or AUTO and the ATU discovers the "bypassed" setting in a tune are identical. It's a real bypass relay pair at either end of the ATU. 73 de Dick, K6KR -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Joel Hallas Sent: Sunday, July 1, 2018 14:10 To: elecraft at mailman.qth.net Subject: [Elecraft] KAT500 Antenna Memories I don't think my KAT500 (FW 01.75) is old enuf to suffer from the kind of memory problems I have, but it doesn't seem to do what I expect it to do.

A bad idea in my opinion.?Jim KC7QY From: W2xj To: KC7QY Cc: "414C6432-07B4-4D92-A502-06E47F34CD41 at elecraft.com" <414C6432-07B4-4D92-A502-06E47F34CD41 at elecraft.com>; Elecraft Mailist Sent: Sunday, July 1, 2018 4:05 PM Subject: Re: [Elecraft] 6M Beacons Context?

Unfortunately it comes with some other compromises. That said, I think a green display on the K3 would be awesome. In a similar, slightly humorous vein I wanted to replace some dial lamps on an old Yaesu with LED's. I had some white LED's and some sandpaper so set to work creating a degree of diffusion. Happy with the result I did a couple more and put them in the rig. The horror show started straight away. The 'white' LED's were in fact multi-colour of the seizure inducing kind, I guess they must call them rainbow LED's they change colour fast, then slow, then flash all colours in rapid succession. Quite the impression but not quite the right effect. Martin, HS0ZED On 02/07/2018 04:47, Bert Craig wrote: > I occasionally pose this question.

I found a log to sit on, in the shade (a luxury at the beach), then deployed the station. Within a few seconds I heard K2K in New Hampshire calling CQ on 20 m SSB as part of the "13-Colonies? operating event. Called him with 10 watts, and since there were many stations calling, I added ?QRP? at the end. Broke the pileup on one call. With a 4-foot whip :) ?QRP? sounds quite distinctive on the air, often drawing the attention of good operators. Timing is key: if you have several stations calling, they?ll all try to get their call in at the same time, pretty quickly, leaving a nice gap right at the end where that magic word can drop in. Give it a try next time you?re operating with low power or compromise antennas. I?m more of a CW guy, but this reminded me how much SSB can be when the bands are open. Also worked a number of VE stations as part of the concurrent RAC contest. I took a photo of the rig, antenna, and a supporting 2-legged ?bipod" that I?ll be happy to share if anyone is interested.

A two-conductor mic plug will short the mic bias to the logic bias. The logic bias is not filtered. I realized that a stereo splitter would separate the logic bias to one channel (where it could be used for PTT) and a mic could be plugged into the other channel with the filtered mic bias. I wrote the two articles because I got really, really tired of posting the same information over and over again to the this list. The problem was originally diagnosed on this list by Lyle, KK7P. He suggested turning off mic bias and using only the logic bias. Separating them out works even better.

The idea advanced to me by others in the know is? legacy receivers such as the K3 and K3S provide better performance when the receiver noise floor is about ~10 dB below no signal band noise.???? If the no signal band noise is -97 dBm or about S-5, and accepting the fact the receiver noise floor is -135 dBm, since we can't change receiver noise floor we must change the signal level to the receiver.?? By adding 15 dB of attenuation and reducing the RF gain by about ~10 dB, this should put one in the "sweet spot" for optimum receiver performance. Works for me every time.? The proper filter adjustments and configuration also helps. 73 Bob, K4TAX On 7/1/2018 7:37 PM, Bill wrote: > > Sent from Mail for Windows 10 > I want to thank everyone for all the response on the lo and hi filters > I tried your advice and they work wonders. > My radio usually runs a s9 with noise and I was able to pull out signals hidden in > It. > This is really an amazing radio > Thanks again for all the help. > Bill > W3WGG > ______________________________________________________________ > 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 k6dgw at foothill.net Sun Jul 1 22:22:48 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 1 Jul 2018 19:22:48 -0700 Subject: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip) In-Reply-To: <47F85FA7-84EB-483E-A321-DF1E42CA97A5@gmail.com> References: <73a8697e-f0e1-db2c-75d9-1abb5e91349f@embarqmail.com> <47F85FA7-84EB-483E-A321-DF1E42CA97A5@gmail.com> Message-ID: <7048306e-531f-1b7d-bbfa-d97022593969@foothill.net> Well, you're close Grant, probably close enough.?

So far, so good -- but he couldn't quite get my call right. There were dozens of guys standing by, and Martti stuck with me over and over, many many tries, until he finally got it.

In a contest no one cares how much power you are running they just want to copy your callsign and report as quickly as possible. Sometimes "QRP" is the only thing that is copiable and it becomes frustrating that the QSO cannot be completed because the actual callsign was not sent enough times.

In-Reply-To: References: Message-ID: Lenny, Are your IF filters aligned so a 550Hz signal is within the passband. With the K2, simply setting STP for 550 Hz will not do it, you must do CAL FIL to make 550Hz appear well within the receive passband. A properly tuned K2 will typically have a good response to a -140dBm signal from the HP8640B. It is easier to take the K2 to the signal generator than to lug that heavy signal generator to the hamshack! 73, Don W3FPR On 7/1/2018 4:35 PM, w2bvh wrote: > I dragged my HP8640B out of the "lab" (basement) to the second floor > shack to do some antenna testing about a week ago.

The "U3S" also has a lot of other features, and can send many other modes too, including CW, QRSS, JT4, JT9, JT76, Opera, Pi4, Hellschreiber, ISCAT. So it is possible to do what Dave NK7Z originally mentioned: a 6m beacon sending both CW and WSPR. The GPS interface on the "U3S" means you can let it run autonomously indefinitely, the GPS disciplines both the time and frequency. I know this is not an advertising forum but several options have been mentioned, including my personal website, and the U3S is a direct solution to the 6m beacon that Wayne was proposing, and is already in use as such by many people worldwide. So I hope it is Ok to mention it here. 73 Hans G0UPL http://qrp-labs.com > That's it!

There are two ways of taking the digest. With good mail programs, the best way is the MIME digest format. Although the details may vary, good mail programs will allow you to decompose the digest. In the case of Thunderbird/Iceweasel, it displays the concatenated messages, with specially formatted header lines, and provides access to the individual messages as though they were attachments. There is a minor bug in that, when replying to a reply, Thunderbird adds an extra "Re:", but that is easily fixed. Doing it this way, rather than just editing out the rest of the digest, has the added advantage that a correct In-Reply-To header is sent, that can help threading readers. (What I really hate is where people ignore the warning at the top of the digest, and simply copy the whole digest, or that part after the message to which they are responding. That cuts short the next digest and also forces one to plough through lots of old postings, possibly to find that the culprit has overflowed the digest size limit and there are no more real items in the digest.) -- David Woolley Owner K2 06123 On 30/06/18 15:09, Lee Murrah wrote: > I am receiving messages in the digest mode.

All the winding info is in the instructions for the KFL1-2, found on the Elecraft site at: http://www.elecraft.com/manual/E740020%20KFL1-2%20instr%20Rev%20I.pdf There were a lot of surplus 40/20m filter boards after the KFL1-4 came out in 2001. Perhaps someone has one for sale, to have 20m parts replaced with 80m parts. There was also an RFC and capacitor that had to be added on the K1 RF board for 80m operation. FWIW, somewhat bizarrely, links to documents for the KFL1-4 four-band filter board are missing from the Manuals and Downloads page of the Elecraft site. Now the two needed files must be selected from this link: http://www.elecraft.com/manual/?C=M;O=D or reached directly from these two links: http://www.elecraft.com/manual/KFL1_4_man_rev_A.pdf http://www.elecraft.com/manual/KFL1-4%20Errata%20Rev%20A-4.pdf It seems to me it would be better to have all this info still available directly at the Manuals and Downloads page for the K1.

Personally, I think what might be needed is some co-ordination on the lower VHF bands, to initiate something like the HF IBP system, where one frequency is used in turn by a collection of beacons.? (Multiple frequencies could still be used, but accommodating multiple beacons per frequency.) Using a Next Generation Beacon mode, you get not only human readable CW, but machine readable modes so you can leave a PC monitoring to build an appreciation of propagation to/from your location. See:? ??? http://www.ncdxf.org/pages/beacons.html ???????? ??? http://www.ncdxf.org/beacon/beaconschedule.html Also, for other idea's: ??? ??? ??? http://www.rudius.net/oz2m/ngnb/index.htm and:? ?? http://www.gb3vhf.co.uk/GB3VHFReceiving.html for some examples. No affiliation, just idea's, to perhaps avoid many beacons all QRM'ing each other. 73 Dave G0WBX. ------------------------------------------------------------------------ On 01/07/18 17:03, elecraft-request at mailman.qth.net wrote: > Subject: [Elecraft] Proposed: more 6 meter CW beacons > Message-ID: <062211FF-E9F9-4C6D-A665-C0A8F38A5BF6 at elecraft.com> > Content-Type: text/plain; charset=utf-8 > > When 6 meters opens up, a few low-power CW beacons I?ve never heard always pop up in the low end of the band. We could use a lot more of these during sporadic-E seasons. If you have a 6-meter-capable QRP rig gathering dust and an antenna to put it on, you might consider joining in.

In-Reply-To: References: Message-ID: <3c379b6d-d36a-9146-99b0-a350fd89158f@comcast.net> Thanks Don, As you say, I also would expect the signal from the 8640B to be clearly audible at -140 dBm on the K2. I took your advice checked the filter bandwidths. I used the old noise source I built when I originally built the K2 ( Tom Hammond design?) along with the filter measurement instructions from your web site, and the Spectrogram 5.17 program.? No changes were needed. The filters are centered on 550 Hz. So that is not causing the MDS problem. It was well worth doing to eliminate that as a possible cause. The reply on the Elecraft reflector from KN5L was helpful for me to make more MDS measurements and help me validate the ones I made originally. I used the instructions that come with the XG3 manual to set up the K2 and calculate the MDS. I used the 8640B as the signal source.? The results of those measurements are: _XFil BW Hz) ?????????????????? MDS (dBm) _400????????????????????????????????? -125 700????????????????????????????????? -123 1500??????????????????????????????? -121.5 So these results are actually a couple of dB WORSE (at the same bandwidth)? than the ones I originally got (e.g. the ones from my original email to the reflector a couple of days ago). Any additional advice you may have would be greatly appreciated. I don't know if you have fixed this type of problem before, but if you have, maybe I should be mailing it off to you to fix it? I did a qrp-qrp qso with an F5? last night on 40M, but it was pulling teeth to copy him. Another 1 1/2 s-units (or so) of signal would have been very welcome! Please let me know either way. 73 & happy 4th, --Lenny W2BVH ps - as for bringing the siggen to the K2? or vice versa, the siggen had to be upstairs in the shack for antenna measurements (can't bring the antenna connection down to the basement ;-).?

Each indicator must be separated from the assigned call sign by a slant ("/") or any suitable word that denotes the slant mark ("portable," "stroke," etc.). If the indicator is self-assigned, it must be included before, after, or both before and after, the assigned call sign (example "KP2/W1AW/contest").

Is transmit power full output? If both are correct, you will have to go through the Receive Signal Tracing in the Troubleshooting Appendix of the manual. If you have an oscilloscope with a 10X probe, you can use the HP8640B to drive the K2 receiver input.? Set the signal generator so you have an obviously measurable signal at the BNC jack.? The signal level should decrease only slightly through the T/R switch, but will decrease some through the BandPass filter.? The preamp will bring it back up as will the Post Mixer Amplifier. If you can achieve enough signal to give you as much 'scope deflection as the listed "Expected" values, that will give you some guide for the signal levels along the receive path. I can usually make a judgement about the relative levels as I progress through the receiver without consulting the receive chart, but then I have had a lot of practice. Note that with the inclusion of the back to back diodes across the IF amplifier, the expected values after that point have changed - if you get to that point, you can temporarily remove one end of the diode pair. 73, Don W3FPR On 7/2/2018 2:22 PM, w2bvh wrote: > Thanks Don, > > As you say, I also would expect the signal from the 8640B to be > clearly audible at -140 dBm on the K2. > > I took your advice checked the filter bandwidths.

Having lost out on two KX3s I'd thought I'd agreed to purchase in the last two days, I decided to try my luck here. I'm looking for a nice used KX3. Later serial number would be nice and the tuner, dual passband filter and battery charger options would be a plus, but for the right price, not necessary. The original box and manuals would also be nice, but again, for the right price, not necessary. Not be be blasphemous, but I picked up a new Yaesu FT-818 at Dayton, if anyone here is interested in some kind of trade. The FT-818 is new and comes with the case and an extra high capacity battery from Batteries America, along with everything that a new one comes with. Please don't scold me for the FT-818, I know what I did was wrong and I'm trying to right that wrong now... Please reply to my email to avoid list clutter and 73 to all!

What happens is the Macro executes, but when it completes, the P3/SVGA switches the Center Frequency back to the previous band and the band the radio is on is correct but the SVGA display differs from the P3 itself by quite a bit.? For specifics, I test the Macro by switching to 28MHz band.? After execution, the P3 shows the 28MHz center frequency but the SVGA shows 74Mhz, or thereabouts.? - If I change the SPN, the center frequency varies. Suspicious. What I am trying to accomplish is this: Change bands(6m), Set Mode(Data), Set VFO-A Frequency (50313), Set P3 Center (50315) and P3 Span (4.3) The idea is to have the audio bandwidth of FT-8 on the SVGA display (in this example). What obvious mistake am I missing and forgetting?? Thank you. 73, Byron Note the results are the same whether in a Macro button or some the test command line. The results are fine when the command is broken up.? I do know about delays in command execution, especially band changes, and it does work better when you are already on the band.

All Apple products should be wired the same way. The two standards are AHJ/CTIA and OMTP. Most modern phones use the AHJ/CTIA spec. See: https://help.longtailproducts.com/hc/en-us/articles/207970396-Smartphone-Headset-Standards-Apple-iPhone-AHJ-CTIA-OMTP A clever way to adjust compression is to use the two voice memories and play back different settings to compare them. Turn the power down to zero first! That was a suggestion from Lyle, KK7P. Also, it is probably best to set TX EQ before setting compression, because the frequency content of your voice will probably interact with the compressor. I compiled audio setup steps gleaned from this list in a blog post. https://observer.wunderwood.org/2015/09/09/transmit-audio-and-compression-with-the-elecraft-kx3/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jul 2, 2018, at 5:23 PM, Wayne Burdick wrote: > > >> On Jul 2, 2018, at 5:20 PM, Phil Hystad wrote: >> >> Do you recommend speech >> compression set to max or was that just a test of audio quality check. > > I generally leave TX CMP at 20, but even at 30, the audio is very clean.

The RF input from the K3S or the KX3 goes through a two position coax switch. Having both connected at the same time has not seemed to cause any identifiable problem in going back and forth between the two driving transceivers. The question is may I make the same connections through the KAT500, the K3S connected through the KAT500 via AUX cables and the KX3 connected to the KAT500 via the PTT RLY connections. It appears that the internal inhibit relay opens both lines when an interrupt is necessary and that other than that the two connections are in parallel.

I would set the fan to a speed that provides some air flow without being annoying. Perhaps speed 2 or 3, if I recall correctly. This should at least delay it turning on the noisier higher speed speed fan and may minimize some of the cool down clicking. John KK9A from: Bob McGraw K4TAX date: Tue Jul 3 09:24:13 EDT 2018 In running my KPA500 on FT-8 mode at about 400 watts output, what is the recommended setting for Fan CTL? I usually keep it in NORmal but have tried other settings. I watch the TEMP and see that it gets above 65?C. The fan speed increments up and down as the temperature changes accordingly. All appears norms. But, do you find setting the Fan CTL to some value is more efficient in regard to cooling? Thanks in advance for your inputs. 73 Bob, K4TAX From a.durbin at msn.com Tue Jul 3 11:52:58 2018 From: a.durbin at msn.com (ANDY DURBIN) Date: Tue, 3 Jul 2018 15:52:58 +0000 Subject: [Elecraft] KAT500 antenna selection Message-ID: I have a new KAT500 and am learning how to use it.

Each band can select up to three antennas to use.? One of the options is 'Last Used'.? That may apply to your station. Antenna selection cannot be determined without using the utility. If your antennas are multiband, the tuner can be taught which antenna on which band(s). If the tuner is not programmed for a specific antenna on a given band, you cannot override it from the front panel, this is logical and protects from accidental choices. Once you have the selection correctly set (SAVE) you can 'teach' the tuner on each antenna on each band segment, per the manual. It will remember (use save in the utility). The time you take to correctly program the tuner saves you hours of grief later.? It's time WELL spent.? Then leave the tuner set in manual mode so it doesn't attempt retuning if something occurs during use (a branch brushing a wire, an unfortunate bird action). I DO suggest that you (after complete setup)? at least glance over to the SWR LED display during operation to ensure things are as you expect, even after some time of successful use. 73, Rick wa6nhc On 7/3/2018 9:39 AM, Dennis Moore wrote: > Manual/Automatic is not used for overriding antenna selection, it > turns on or off the automatic initiation of a tune cycle when high SWR > is detected for the antenna that is currently selected.

Rather, we should be looking at the indicated gain reduction on audio peaks, and 10 dB is a good objective. As an audio pro, my advice is 1) set TXEQ so that you're not wasting power transmitting low frequency speech sounds (max cut for the first three bands, 6 dB cut for the fourth)? 2) Set CMP for the indicated value of gain reduction? 3) Get some signal reports from a good listener. This combination results in about 13 dB of increased talk power (3 dB for the EQ, 10 for CMP). 73, Jim K9YC From jim at audiosystemsgroup.com Tue Jul 3 13:23:11 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 3 Jul 2018 10:23:11 -0700 Subject: [Elecraft] KPA500 Fan Question In-Reply-To: <1801fc8e-cbf7-18fe-e39b-0036659eac56@blomand.net> References: <50D66F9F-EC0B-4F87-B904-7BDF76B78FB5@mac.com> <1801fc8e-cbf7-18fe-e39b-0036659eac56@blomand.net> Message-ID: <27e4e302-68d3-8a0a-d5c7-c2314e712bcb@audiosystemsgroup.com> On 7/3/2018 6:24 AM, Bob McGraw K4TAX wrote: > In running my KPA500 on FT-8 mode at about 400 watts output, what is > the recommended setting for Fan CTL????

I'm running meteor scatter and weak signal work, which means I'm transmitting on almost every cycle. To keep TEMP relatively low, I set the fan to either max speed or one step down. Into a different antenna on FD, the same amp ran significantly cooler. Using an LP100A power meter, I get at least 500W out on 6M, sometimes as much as 550W. 73, Jim K9YC From n6kr at elecraft.com Tue Jul 3 13:27:31 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 3 Jul 2018 10:27:31 -0700 Subject: [Elecraft] Adapter for use between iPhone headset and a KX2/KX3 In-Reply-To: <67c277f0-7cab-3dd6-d08b-0afe7dd78d45@audiosystemsgroup.com> References: <3153272B-97A1-413E-9EF8-C96C1DADD05B@mac.com> <5E76129D-3CB6-4DAE-8C8E-A9943B7C2B91@elecraft.com> <67c277f0-7cab-3dd6-d08b-0afe7dd78d45@audiosystemsgroup.com> Message-ID: <8BD8D078-9A02-4CF7-BC51-F44D122F5E56@elecraft.com> The numeric value is a relative indication generated by the math we use in our algorithm; it?s not actually an attempt to quantify compression in dB. Multiple factors including power level, ALC level, and mic gain setting are taken into account. I?ll dig up the full details of the implementation when I get a chance. Meanwhile (anecdotally): at any setting the compression is very clean, and at the high end it greatly increases the ?punchiness? of the signal.

Here is a specific example of a case that I don't understand: My configuration for 40 is Enabled 2 and 3. Preferred 2 My configuration for 20 is Enabled 1 and 3. Preferred 1 I select Auto and TX on 40 - Ant 2 is selected automatically and only 2 and 3 are manually selectable (all as expected) I select Ant 2 and then select Bypass I TX on 20 - Ant 2 remains selected and high SWR is shown I attempt to manually select Ant 1 but only 2 and 3 are selectable I select Auto and Ant 1 is auto selected. Now Ant 1 and Ant 3 are manually selectable. When in Bypass, either the Antenna selection should not be inhibited by the selection table, or it should be forced to match the selection table. What I see is that is forced to mismatch what's in the selection table. Would someone at Elecraft please try to duplicate this test sequence and explain why it should work this way.

While all rigs have certain strengths, the K3S has a combination of performance, features, and form factor that provide unique benefits to the operator, especially those who may encounter high-signal conditions or require portability (or both, as in the case of Field Day, DXpeditions, etc.). The comparison table is in draft form and will continue to evolve, so we?re not posting it on our website just yet. However, we?ll be happy to send the current edition on request to anyone actively weighing the tradeoffs between the K3S and other transceivers. Please email me directly if you?re interested. I?ll be happy to expand on information presented, whether theoretical or functional. No doubt these discussions will help us refine the table. 73, Wayne N6KR From n6kr at elecraft.com Tue Jul 3 15:36:58 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 3 Jul 2018 12:36:58 -0700 Subject: [Elecraft] FT8: "Magic radio"?

I still have a beating heart for my first ?personal computer?. For it?s time (late 50?s to early 60?s) it was a very smart and very fast, fully asynchronous, about 1 Mhz, machine with around 1000+ vacuum tubes, and one of the earliest machines (if not THE earliest) with dynamic memory allocation. I?m sure the Apple watch could easily outdo it now, just to display the time. I?d bet there will at some point be a version of the ?Teensy? that will be more than capable of running a contest without operator intervention, maybe with a link to Watson .. or not. There certainly ought to be a separate category. At least for the few of us old and getting older curmudgeons left that still use pen and paper logging and a sideswiper key (or heaven forbid ? AM). And that actually use the knobs on our radios to tune ? :-) :-) One of these days I?m going to get my Digital Group Z-80 out of the box, replace the one missing chip on the CPU board, and threaten everyone :-) Grant NQ5T K3 #2091, KX3 #8342 SKCC #18434 > On Jul 3, 2018, at 3:36 PM, Wayne Burdick n6kr at elecraft.com [KX3] wrote: > > Overheard yesterday on 40 meter SSB, in reference to FT8: ?Given the level of automation and whatnot, maybe they should call it ?magic radio? instead of ?ham radio?.? > > New contest category? > > From n8vz at qth.com Tue Jul 3 16:04:40 2018 From: n8vz at qth.com (=?utf-8?Q?Carl_J=C3=B3n_Denbow?=) Date: Tue, 3 Jul 2018 16:04:40 -0400 Subject: [Elecraft] FT8: "Magic radio"?

I?m now about halfway through and I?m doing better than I could have ever imagined. I?m not going to ever be a very fast CW operator, and sending will be a whole new challenge, as my manual dexterity and sense of rhythm are not very good, but I do see the light at the end of the CW tunnel, which for me has been a real challenge. And, I also do FT8. In fact, I got WAS with FT8 in only about one month. I wasn?t planning on an FT8 WAS endorsement, but when I noticed that I had 35 states without even trying, I thought I might was well go for it. So, in my case, FT8 has killed CW interest at all, in fact, it might have played a small part in increasing my interest. Maybe one day, I can get WAS CW endorsement. That would be a real accomplishment for me. 73, Carl N8VZ Sent from my iPad > On Jul 3, 2018, at 3:48 PM, Fred Jensen wrote: > > The last Q in the FAQ at the end of Dr. Joe Taylor's instructions for use of the DXpedition ["Fox and Hound"] mode of FT8 is: > > "Are you trying to kill CW?" > > If he is trying to kill CW, listening on 14023 and up suggests that he is failing. > > 73, > > Fred ["Skip"] K6DGW > Sparks NV DM09dn > Washoe County > >> On 7/3/2018 12:36 PM, Wayne Burdick wrote: >> Overheard yesterday on 40 meter SSB, in reference to FT8: ?Given the level of automation and whatnot, maybe they should call it ?magic radio? instead of ?ham radio?.? >> >> New contest category? >> >> 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 n8vz at qth.com From a.durbin at msn.com Tue Jul 3 16:10:16 2018 From: a.durbin at msn.com (ANDY DURBIN) Date: Tue, 3 Jul 2018 20:10:16 +0000 Subject: [Elecraft] FT8: "Magic radio"?

Had another whoopsie with my K2 Serial #7818. Number 4 wire, that attaches the encoder subassembly to the front panel, had a soldering pad disintegrate. I found this when I was testing, and saw that the encoder was not changing the frequency up or down. I am assuming that the wire not being soldered would cause the encoder to fail the test. I?ve had my kit together and apart multiple times now. I may have caused the malfunction by separating the boards too many times? Regardless, I?ve contacted Elecraft Parts and requested a new encoder subassembly PCB. Hope I can get just the board and not have to buy a whole subassembly! Other than that issue, I?m thrilled with my kit, and excited to continue populating the RF board. Do you think I should continue, or should I wait for the new PCB and complete the testing before continuing? I guess that is one of those ?Are we there, yet?? questions!

The primary differences from RTTY is that it's narrower, better utilizing the band space; it can easily work below the noise floor (not a dream of a chance with RTTY) and that FT8 is simpler for most folks than RTTY (point, click, connect). I score it as semi-automatic since an operator must still manage it; the signal strengths are more accurate (meaning honest) than the eternal '599' (after ten retries) and the largest bonus is that it keeps interest alive in the bottom of the cycle AND allows meager stations to have an improved shot at improving their DX standings.? It's a breath of fresh air to reinvigorate ham radio at some level.

This ham literally has 100W and a wire dipole, only half of which is outside - and is in the log at KH1/KH7Z with a 20M FT8 QSO. Amateur Radio is a technological pursuit.

Personally, I got bored with it after about a week and moved on. Certainly, it?s the cat?s meow if all you care about is logging someone, somewhere, without doing any work, other than making sure you have the right Windows drivers installed and the right boxes checked, and don?t care to find out what the other guy?s name is or what he/she does when they aren?t punching at their own keyboard (well, you don?t even have to do THAT very often).

In-Reply-To: <69B60D8A-9797-4468-B70D-97D60C0E1335@qth.com> Message-ID: I can't resist. My accomplishments: I have a DXCC with 150+ LotW confirmed entities. I have over 100 entities on both digital and CW, less on voice. I have a triple play WAS. I have 5 contacts with KH1/KH7Z in their log, 2 CW, 2 FT8, and 1 SSB. (I'm missing RTTY.) I'm active in ARES/RACES, and like to rag chew, either on the local repeaters, or with PSK31. I'm trying to be a well rounded ham. I look at FT8 as another step in station automation. Back when I started, in the early 1960s, it was normal to have separate transmitters and receivers. Frequently people would have to manually switch the antenna between the two. Now we have full break in with CW. That's an advance in station automation. We used to keep logs on paper, now many of us keep them on a computer reducing the chance for error in details like frequency and time. FT8 carries it a step further by building a log entry which includes the call, grid and signal reports. That's an advance in station automation. We used to scan the bands by turning the big knob to locate other stations. Now we have spotting networks and panadapters. That's an advance in station automation. When one station wanted to call another, it had to transmit for a long enough time so the other station could find him. CQs were long for the same reason. Now we can change to his listening frequency and make a call. Many people use this technique for working DX pileups. FT8 makes it even more automatic by highlighting all messages that include your call sign. That's an advance in station automation. Where do I come down in all of this? I'm all over the place. In CW contests, I operate unassisted because I want to improve my CW skills, and getting the calls from a spot or decoder doesn't help me toward this goal. When working as part of a contest team, I'm happy using everything that is legal for our entry category. When trying to work rare DX, I'm quite happy running power. I just want to put out a clean signal and not be too obnoxious to other hams. I've heard a lot of comment about various contest rules being too automated or requiring facilities that are not available to everyone. For example contests that provide real-time score tracking. Here I think we should let 1000 flowers bloom. Sure, enjoy Straight Key Night (SKN) and bring out your boat anchor and old paper log book. But also have contests where contesters and an audience can keep track of the scores in real time. Some people can't do CW and sit SKN out. Others may not have the Internet connectivity needed for the real-time contest. In the old days, many hams did not have a Teletype machine for RTTY contests and had to forgo RTTY contacts. Do what you enjoy. Ham radio is a very big tent. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz | Re: Computer reliability, performance, and security: 408-356-8506 | The guy who *is* wearing a parachute is *not* the www.pwpconsult.com | first to reach the ground. - Terence Kelly From jim at audiosystemsgroup.com Tue Jul 3 17:13:00 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 3 Jul 2018 14:13:00 -0700 Subject: [Elecraft] FT8: "Magic radio"?

While I've worked hard to improve my operating skills, transmitter, antenna, feedline, understanding propagation, working to find and kill receive noise are also part of it. And don't discount operator skill with WSJT modes -- knowing when to call, where to place yourself in the frequency window, all are things we need to learn. If I can work expeditions with FT8, I'll find better things to do with my time than sitting in a pileup for hours with guys tuning up or calling on top of the DX, which then brings out the childish "cops" cursing them and "yelling UP idiot." 73, Jim K9YC From wes_n7ws at triconet.org Tue Jul 3 17:16:24 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Tue, 3 Jul 2018 14:16:24 -0700 Subject: [Elecraft] FT8: "Magic radio"?

The amount missing can be either a truncation or parts of the message below the decoding threshold. The FT8 message is structured with sync symbols at the start, middle and end so missing the start or end may have less impact than missing other parts since mostly sync symbols may be lost and they contain no message information." Hence, I dubbed the mode, "Imaginary"? since it hears things that aren't there. Wes?

The MDS problem is now apparently fixed! Before doing the signal tracing, I decided attend to a simple set of repairs on the K2 which I've put off for awhile. I changed the Ext Spkr jack on the back and the Headphones jack on the front (both? of which were starting to get unreliable). Also replace the AF Gain pot, which has been noisy for awhile (and with a loose shaft). After making the changes, just for giggles, I re-checked MDS using the same method as I used before (the one described in the XG3 manual). The results are: before: -125,? after -141.? Did measurements at other bandwidths and have similar offsets? with the other bandwidth measurements done before the fixes. The 8640 signal is audible now with a drive level of -140 dBm, which is good sanity check on the "fix". I guess I was losing 16 dB of gain in the audio portion of the K2 because of one of the replaced components.? I'm glad it worked out this way. I figured you'd be interested in hearing the news.... And thanks again for your advice. 73, --Lenny W2BVH On 7/2/2018 6:13 PM, Don Wilhelm wrote: > Lenny, > > Check the obvious - is the Receive Antenna (RANT) on? > Is transmit power full output? > > If both are correct, you will have to go through the Receive Signal > Tracing in the Troubleshooting Appendix of the manual. > If you have an oscilloscope with a 10X probe, you can use the HP8640B > to drive the K2 receiver input.?

In-Reply-To: Message-ID: Yes to both. I have taken advantage of the ability to receive, even with long dropouts, by turning off my transmissions for a few seconds to see if I'm on top of another station and therefore having more problems getting through. This ability also helps with noise bursts. The QRM solution is inspired. If wsjt-x decodes a signal, it will back encode that signal and subtract encoded signal from the received signal. Frequently it can then decode a station on the same or a nearby frequency. These "second decode" stations are reported at the end of the decoding report. 73 Bill AE6JV On 7/3/18 at 2:17 PM, jim at audiosystemsgroup.com (Jim Brown) wrote: >And I suspect FT8 has much better immunityto noise and QRM. -------------------------------------------------------------- Bill Frantz | There are now so many exceptions to the 408-356-8506 | Fourth Amendment that it operates only by www.pwpconsult.com | accident. - William Hugh Murray From kq8m at kq8m.com Tue Jul 3 17:38:44 2018 From: kq8m at kq8m.com (kq8m at kq8m.com) Date: Tue, 3 Jul 2018 17:38:44 -0400 Subject: [Elecraft] FT8: "Magic radio"?

There is still plenty of skill in working FT8 if the goal is to get in and get out quick just like any more. Hey if you have all day to work someone chances are you will get them sooner or later.

(G4WJS was responding to my concern about K3's timing issues on FT8 delaying transmission.) Now the JT65 guys "copy" callsigns by looking up the closest sounding one in a database with the program saying "Ah ha" that must be the one. I realize that contest software does the same guessing these days, but I don't regularly operate in contests, so I use my regular log and type it in myself. Regards, Wes?

In-Reply-To: References: Message-ID: Andy, that's not right ... you have to be in the shack to make sure the system keeps calling as there is a 2 minute timer that will turn off your transmission.???? It is also suggested that if you don't get a reply back after the first two minute period, manually move the Tx freq. Finally, once you do get that final acknowledgement from the DXpedition, you have to physically log the QSO.? It does not do it automatically. From the DXPedition mode user guide: "You may keep calling until he answers, perhaps changing your Tx frequency in the hope of finding a frequency clear of interference. Use Shift+Click on the waterfall to change your Tx frequency ? the red ?goal posts? marker on the waterfall scale. You will need to re-activate Enable Tx (or hit Enter on the keyboard) at least once every two minutes. (This restriction is to ensure that an operator is present and paying attention.)" As far as it still running, you must have missed this part of the Users Guide for HOUNDS in Item 12: "Note that WSJT-X will send this message even if Enable Tx is disabled, and even if you have not called Fox for several Tx sequences. If you have stopped calling Fox because you will be leaving the rig unattended, you should quit WSJT-X or disable Hound mode in order to avoid the possibility of unwanted transmissions." So again, the operator is still in charge of what he's doing. All that said, there are a lot of people who live in very compromised locations that now have KH1 in their logs because of FT8. Unfortunately, it wasn't me.?? My location is such I didn't hear them on any mode.

My limited math abilities express then relationship as- ? Dm(S10?+O?)=K? ??Kd(S?+O10?)=K Where Dm=Digital Mode????????? Kd=Knoband Dial radios????????? S= Setup ????????? O=Operating????????? ?= Time?????????K= Total effort ? Revisionswelcome-----??? Doug Millar K6JEY Dr.Doug Millar EdD.

The structured messages allow for redundancy if some of the original message is missing. The decoder can take the sync symbols so that the system can understand what type of message it is, it still needs the callsign and signal report.

I quickly got bored, but since there really wasn't any good DX floating around, I got addicted to it, just working for WAS, etc. One day in April, I had an Elmer tell me about /pskreporter/, to use in seeing where I was being heard, etc. One evening when 20M was pretty wide open to the east (AS and EU Russia) and west (Japan, China, VK/ZL), I noticed hams were being reported all around Uzbekistan, one of the dozen remaining entities I need. I looked up on a few websites that had active UK? Uzbekistan hams on the air. There was UK9AA, active and on FT8!!!! I had never heard Uzbekistan in many years and was excited maybe I could work him on FT8. Well, you can guess the rest of the story. I emailed him, Fedor, and we set up a sked, eventually completing the qso on FT8 on 20 meters! With 70 watts at that! Wow, that was easy! Since then, I have worked over 75 countries w/o even trying on the new digital mode! It's still not as exciting as grabbing a rare on on CW, but it sure gives one another tool to work the rare one! ----- Roger W5RDW -- Sent from: http://elecraft.365791.n2.nabble.com/ From w2bvh at comcast.net Tue Jul 3 23:10:26 2018 From: w2bvh at comcast.net (w2bvh) Date: Tue, 3 Jul 2018 23:10:26 -0400 Subject: [Elecraft] FT8: "Magic radio"?

The tradeoff is that the QSOs are highly structured. Not much opportunity for "How's the weather in Dogpatch?" But if you're willing to accept the tradeoff you can make QSO's that would otherwise be IMPOSSIBLE.? If you're not willing to make the tradeoff the other modes are still there for you, just maybe not with some OM's you'd like to work. I worked an HA the other night using FT8 with no repeats needed, and I didn't even see his signal on the waterfall. That's a Q that could not have been made otherwise.?

For example contests that provide real-time score tracking. Here I think we should let 1000 flowers bloom. Sure, enjoy Straight Key Night (SKN) and bring out your boat anchor and old paper log book. But also have contests where contesters and an audience can keep track of the scores in real time. Some people can't do CW and sit SKN out. Others may not have the Internet connectivity needed for the real-time contest.

I have had good luck with an h bridge motor driver based on the irf3205 that are sold for robotics. 73, Mark W7MLG From wes_n7ws at triconet.org Wed Jul 4 09:46:48 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Wed, 4 Jul 2018 06:46:48 -0700 Subject: [Elecraft] FT8: "Magic radio"?

You can then program it using the KX3 Programmers Reference. Or, you can check out the TuneMatic products from JT Communications. He's already done the work and it works with the KX3 standing along or with the KX3/KXPA100 combo for mobile applications. Tarheel Antennas also resells this controller. I'm sure there are others but I see Jim Trapani (JT Communications) in a booth at the hamfests.

Subjecting it to varying temperatures and humidity is something else. Obviously, high temps and humidity will be a problem for any radio. You need reasonable climate control no matter what. The reason I'm responding to this is because eventually the only way I will be able to operate is to place a transceiver in a shed on a friend's property and use a multiband antenna -all of which will be operated over the internet. The ambient RF noise in my townhome makes any HF operating impossible. A 5000 BTU air conditioner can be obtained from many retailers for very little money. This would solve humidity and high temperature issues. Unless the low temperatures are extreme, I don't think its much of an issue.

Yes, I agree the K3 is pricy but the performance is there. However for most things the IC-7300 does a grand job as does the TD590s. For now and for some considerable time in the past though the K3 has had a superior receiver good in contests and with high power neighbours. Other K3/S advantages: 1)Modular construction allows one to only purchase what is relevant to your needs and to build the radio up over time if desired. This also facilitates repair as modules can be swapped or sent back to California. No need to send the entire radio. Elecraft if you make a new radio in the future try to maintain this modular approach. 2) Just what type of support does one get from Icom? I very much doubt there is an equal forum with the designers involved. Support from the factory in getting questions answered is also excellent. 3)More attention should be given to the clean output signal of the K3. 4)I wonder if the facilitation of digimodes by the 7610 is the equal of the K3/S. 5) There is a very full line of accessories for the Elecraft line and again all of this is modular. 6) The ability to at least assemble the radio gives the owner of a kit built radio a better understanding as to operation and trouble shooting if ever needed. It also saves on import duties into the EU. Maybe Wayne should toot Elecrafts horn for these advantages as well. Again though you can work DX with an old FTDX 100 or Drake 2B with Johnson Ranger at much lower cost it will not be so well facilitated. The fully equipped K3 is not an inexpensive radio it is a Porsche of the radio world. I can not imagine a company better than Elecraft to deal with though I understand that Flex is pretty good and so to has TenTec been in the past. Are they as good - this is hard for me to believe. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Doug Person Sent: 04 July 2018 17:11 To: elecraft at mailman.qth.net Subject: [Elecraft] K3S VS: IC-7300 I didn't see any comparison chart for the K3S and the IC-7610.?

The fact that I still do not have a 7300 may indicate the results of my fact finding. My reasoning is simple: The K3 is a great radio, certainly part of the equation. The Elecraft product support is the other part of the equation. I have been there and done that with the other manufacturers and I have no desire to attempt to work with them again. Life is too short to have to deal with rudeness, shoddy workmanship, outright lies, and total lack of customer respect. I have experienced same with the big three and Flex. Happy 4th of July!

An exaggeration by those who don't want to use the mode and discredit those who do. What do I know -- I'm one of the younger guys -- only licensed since 1955, Extra only since 1959, primarily worked CW all my life except for contributing to our club score for contests. I do a lot of RTTY contesting, but I have yet to meet anyone who can copy RTTY with their two ears. And radio is FAR more than pushing buttons, yelling in to a mic, or doing CW. It also includes maximizing your station and understanding propagation, antennas, transmission lines, noise suppression, and operating skill. It is totally false that WSJT modes require no operating skills. Knowing where to place your signal in the waterfall, what to do when QRM causes problems, understanding that you can call a station when he's having difficulty with another QSO (the equivalent of "tail-ending" with other modes) and so on, are also a factor. If you don't like a mode (or don't want to learn it) don't use it, but don't disparage it by saying things about it that aren't correct. 73, Jim K9YC From wc2l at wc2l.com Wed Jul 4 15:55:29 2018 From: wc2l at wc2l.com (William Liporace) Date: Wed, 4 Jul 2018 15:55:29 -0400 Subject: [Elecraft] Low Voltage Band Data Output In-Reply-To: <9e68eae1-5219-f746-9973-1722f9b8ac65@wc2l.com> References: <9e68eae1-5219-f746-9973-1722f9b8ac65@wc2l.com> Message-ID: I really should have said antenna switch controller.

However, the IC-7300 comes well featured already, e.g., 100 watts, spectrum display, built-in tuner ( mine does much better than 3:1), effective digital filters, voice recorder for receiving and sending. > 2) Just what type of support does one get from Icom?

Ten-Tec has been (past tense since they pretty much don't exist at the moment) great. No argument regarding the involvement of Wayne and Eric in this group.

The K3/K3S outputs BCD band data. You need a decoder box to convert that into direct drive signals (high side drive) for both of the antenna switches. The Elecraft KRC2 will do the job quite well, as will quite a few other boxes. Be sure they have TTL-level inputs. The ones with opto-isolators tend to require quite a bit of current, more than the K3/K3S may be able to drive. Some will work, others, even from the same manufacturer will not. 73, Jack, W6FB > On Jul 4, 2018, at 12:55 PM, William Liporace wrote: > > I really should have said antenna switch controller.

You said it all. I don?t understand complaining about a mode you obviously have never used. As someone else said, FT8 has its positives and negatives. What I don?t like are the ops running a gallon or more. I consider QRO for the JT modes and PSK to be 100 Watts. I?ve only gone that high a few times to bag a difficult one. I usually use about 35 watts, which some purists will say is way too much. I?ve worked stations around the world who report they were using 1 watt or less. If properly used, these weak signal modes are truly amazing! 73, Carl Sent from my iPhone =========================== Carl J?n Denbow, N8VZ 17 Coventry Lane Athens, Ohio 45701-3718 carl at n8vz.com www.n8vz.com EM89wh IRLP 4533 Echolink 116070 PSK and JT65 Forever! =========================== On Jul 4, 2018, at 3:36 PM, Jim Brown wrote: >> First, I haven't read through this entire thread. >> >> I've been a RTTY guy for a long time and am in the #1 spot on the RTTY DXCC >> Honor Roll.

It also includes maximizing your station and understanding propagation, antennas, transmission lines, noise suppression, and operating skill. It is totally false that WSJT modes require no operating skills.

I guess we never met, Jim. I can copy CQ, 599, and my callsign in Baudot RTTY. Many years ago, there was a Dxpedition I was calling. There was a selective fade when he responded to the pileup and it didn't print. However, I knew he came back to me from what I heard. When he came back with the TU, my callsign printed to confirm it. Baudot RTTY is slow. I can copy CW at almost twice its speed, but that isn't a requirement, as I know a few other RTTY contesters who can also recognize their calls on RTTY.

Message-ID: <06D370AF-5CE8-454B-A3E8-F5275908D68F@me.com> As there are only one or two days left before the KH1 crew packs up and leaves Baker Island, I thought I?d post this in hopes that other antenna-restricted hams don?t think they have no shot. I live in a CC&R / HOA ?no ham antenna? neighborhood. However, I DO have several stealthy wire antennas strung through the trees in our yard. My 60-6 meter antenna is an 88 foot long doublet, about 45 feet high, fed with 110 feet of home brew 600 ohm ladder line. I also have a Hustler 5BTV ground mounted that I use for diversity receive. My primary station is a K3 / P3 combo, 100 Watts max. I had tried working the DX-petition on several evenings, usually on 20 or 40 meter CW. The pileups were horrendous. I knew I was duking it out with guys running mega antennas and a LOT more power than me, so I didn?t have much hope after the first few evenings. Usually went to bed with a headache and frustration. Last night was different. After an evening of TV with the XYL, I thought I?d give it another try. Listened on 20 and I could hear them, but just barely at the noise level; not loud enough to try calling. So I jumped up to 30 meters. Wow - the KH1 station was great copy at close to S7! And the pileup was once again monumental. Well, using the P3 I found a nice ?hole? where it seemed like there were no other signals. Took about 15-20 minutes and.... bingo: W6JHB 599 K. Yes! In the log for an ATNO! My hats off to the great ops at KH1/KH7ZZ and to the Elecraft developers for the fine rig. Having the K3 and the diversity receive capability certainly helped offset having to use crummy antennas and ?low? power. If I could work ?em, so can you! Yeah, I know - being on the west coast helps! :-) Jim Bennett / W6JHB Folsom, CA From wc2l at wc2l.com Wed Jul 4 19:54:52 2018 From: wc2l at wc2l.com (William Liporace) Date: Wed, 4 Jul 2018 19:54:52 -0400 Subject: [Elecraft] Low Voltage Band Data Output In-Reply-To: References: <9e68eae1-5219-f746-9973-1722f9b8ac65@wc2l.com> Message-ID: OK, the answer was to put a lower resistor in the input.

When I hook up a cable to the ACC plug for band data output, I get about 4.8v (slightly less than 5v). When I hook up the radio to any antenna switch that has band data input, the voltage goes down to 3v. This is not enough to drive the antenna switches.

Now all are considered giants. There's another similarity -- Diz never drank or did drugs, but a lazy magazine writer said he did, and the lie got repeated for a decade.

I had both radios (but not any more) and currently own K1, K2 and KX3. K3 is a great radio and K3S must be even better, but 7300 isn?t too bad even compared to K3S. When I consider the cost difference, 7300 is an awesome radio for an average guy like me. When I am not happy with service quality with those three Japanese companies, there are always good alternatives like N1EQ. I always give 5 stars to Elecraft, but it isn?t obviously for everyone.

There were no heat or humidity related failures. I see no reason that Elecraft radios and amps would not work after being stored this way. The proposed shed may be even hotter, I would recommend venting and insulating at least the roof. As far as running equipment in a shed, it probably would not like the extreme temperatures. Perhaps a small heater and A/C can be remotely turned on. John KK9A aka P40A Bob McGraw K4TAX rmcgraw at blomand.net Wed Jul 4 20:26:28 EDT 2018 My shop is about 300 ft from our house. In a corner of my 25' x 50' building {not a garage}, I have enclosed a 12' x 15' area, where I insulated the walls and ceiling. This is my radio room which has my test bench and equipment from a former service repair business. $$$$ investment. Due to the investment in the equipment and radios, I maintain a constant environment year around. Heating, cooling and humidity control. Most electronics components have a "storage" environment set of values and an "operating" set of values. These are usually values of temperature and humidity, and in some cases altitude. Just do what and as you think regarding the value for your equipment and hobby. Personally, I certainly would not expose my Elecraft equipment to long term uncontrolled environment conditions without expecting to have problems. 73 Bob, K4TAX From k4to.dave at gmail.com Thu Jul 5 08:38:12 2018 From: k4to.dave at gmail.com (Dave Sublette) Date: Thu, 5 Jul 2018 08:38:12 -0400 Subject: [Elecraft] Equipment Storage and operation Message-ID: I should start with an apology to the group. Although I stand by what I said in a previous post, I feel that the way I expressed myself was in violation of decorum standards for this group. I am sorry for that. After letting my BP come down and thinking about it a bit, I realized that I have useful experience doing the very same thing that the gentleman was asking about. I stored and operated equipment in an unheated, uncooled outdoor environment for over 20 years. To wit, I operated four microwave bands with transverters and amplifiers mounted remotely in a "weatherproof" box mounted at 185 feet on my 200 foot rotating tower. Here is what happened: The equipment was mounted in an enclosure commonly referred to as the "white box project" among microwave folks. It is of very high quality design and construction, having sealed gaskets around the hinged cover and screened vents. The equipment inside consisted of DEMI transverters, which I built from a kit and amplifiers that were originally built for commercial microwave links. The point being, it was all very good quality. I have the test gear to verify that it was all operating with good sensitivity, etc.... Over the course of the time I used it, I had to bring it down every two to four years for repair. Corrosion from condensation was a big problem. On the circuit boards, chip components would crack and solder connections opened, probably from expansion and contraction due to heat and cold. I don't recall any electrolytic capacitor failures, but those would certainly be vulnerable under those conditions. It was first degree abuse of electronics equipment, no doubt. My defense for this is that it was unavoidable because the equipment has to be mounted close to the antennas to minimize transmission line losses. I believe the majority of us that operate microwaves mount our equipment like this and there are many stories similar to mine. Some folks mounted fans and light bulbs in the remote enclosures. The fans removed some of the heat in Summer and the lightbulbs maintained some heat in Winter and kept some of condensation from forming. Short of elaborate measures, I don't know how the operating conditions could be matched to those in a heated and air-conditioned shack. So here is my attempt at constructive suggestion. I still cringe at the thought of putting any equipment in an unheated and uncooled space outside. 73, Dave, K4TO From gerry at w1ve.com Thu Jul 5 08:42:28 2018 From: gerry at w1ve.com (Gerry Hull) Date: Thu, 5 Jul 2018 08:42:28 -0400 Subject: [Elecraft] KX3 controlling K3s over Remote....

I've operated 6M since the mid-80's from the Midwest (Missouri). Propagation on 6M here is often a black hole for RF. Using FT8, there have been frequent EU, SA and JA openings, whereas in prior years they have been few and far between. It's not just propagation, it's the sensitivity FT8 brings to the table that has allowed the band openings to be realized. It might truly be a "Magic Radio" on the "Magic Band." I still check the CW and phone segments, and it's often "crickets" there while it's quite active on FT8. The mode has definitely enhanced my 6M experience. I concur with the comments that using FT8 to its full advantage requires operator intervention and some degree of skill. It's not simply an "appliance mode."

Seems like we might be getting toward OT here? A ?sawzall?, a trivial bit of framing, and a pre-hung window can fix that very quickly. If you are just installing a ?window mount? AC unit, you can save (a lot of) time and money by skipping the window and put the AC unit directly in the hole. If you want the structure to last, seal around the outside to prevent water ingress and long term damage.

Water (liquid/vapor) kills electronics. Now, HOW you control water is the key to longevity.? Basically, you have three factors that impact how well you control the environment:? temperature, pressure, and humidity. If you have all the money in the world, you can produce a standard temp/pressure/humidity in any size volume you want. Money is often the ultimate limiting factor.? Sometimes it is availability of power.... AND money. For a LOT less than they charge for these communications modules, you can produce an environment for your remote electronics that will insure effective performance and longevity for the components. It costs some money, but if you have the skills, energy, and time, you can DRASTICALLY reduce the amount of money it will take to address the situation. To the OP:? WHAT ARE YOUR REQUIREMENTS? Volume of artificial environment?? (length, width, height....? a box, a small room, a radio station?) What equipment do you need to put in the environment....? What are the operating and non-operating specifications for EACH piece?? What is the most restrictive spec for each of the following:? humidity, temperature (high and low), pressure, etc. Bottom line....? you gotta keep the water away from the electronics.... this involves 1) stopping the air pumping action from outside to inside via thermal/temperature and pressure delta pumping action, and 2) keeping the water vapor that IS inside the environment in a VAPOR state and stopping it from condensing.? There are other conditions and mitigation techniques for each. But until we know the requirements, we cannot begin to construct a solution. 73, ______________________ Clay Autery, KY5G (318) 518-1389 On 05-Jul-18 09:18, Walter Underwood wrote: > A good window air conditioner is $200.

The Baker Island folk were reporting temperatures of over 100 F (c38 C) with high humidity. I haven't heard of any problems with the radios, but I'll ask people who were there when they come back. When operating at field day this year, we had similar temperatures with low humidity. The front panel showed 49 C for a long time. While we were operating at 5 watts, rather than higher, I don't think that will affect the front panel very much. The front panel heat is mostly the digital electronics which should be similar regardless of the power output. Certainly if you are installing in high temperatures/high humidity, an air conditioning unit can help with both. Small heaters can help with cold, but I think that is less of a problem. Good insulation will help greatly with temperature cycling by evening out the changes. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz |"We used to quip that "password" is the most common 408-356-8506 | password.

Hi John, The prototype AX1 whip resonates on 17 and 20 meters via a 2-position slide switch. The ATU in the transceiver allows it to cover 15 meters as well (in the 17 meter position). In all cases I use a single 13? counterpoise wire. The coils in the antenna base were selected to get close to resonance on 17 and 20 meters with this wire in place. You can of course use more or longer counterpoise wires. But I?m generally in a hurry when I?m deploying the whip :) 73, Wayne N6KR From jim at audiosystemsgroup.com Thu Jul 5 13:47:38 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 5 Jul 2018 10:47:38 -0700 Subject: [Elecraft] K-Line Climate Control In-Reply-To: References: Message-ID: <64110a09-06a8-b32e-a489-0e893e4cea6c@audiosystemsgroup.com> On 7/5/2018 10:22 AM, Bill Frantz wrote: > The K3S and K3 seem to survive operating in extreem climates.

Hi John, The prototype AX1 whip resonates on 17 and 20 meters via a 2-position slide switch. The ATU in the transceiver allows it to cover 15 meters as well (in the 17 meter position). In all cases I use a single 13? counterpoise wire. The coils in the antenna base were selected to get close to resonance on 17 and 20 meters with this wire in place. You can of course use more or longer counterpoise wires. But I?m generally in a hurry when I?m deploying the whip :) 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 va3on.lists at gmail.com From k5atg.aaron at gmail.com Thu Jul 5 15:54:14 2018 From: k5atg.aaron at gmail.com (Aaron) Date: Thu, 5 Jul 2018 14:54:14 -0500 Subject: [Elecraft] KX3 Using FLDigi to send CW Message-ID: A year or so ago, someone told me how I can send CW with a KX3 using FLDigi and a SignaLink USB Sound Card.

You have the use the ATU TUNE button for it to tune. AUTO means the ATU will automatically set the L/C combination that was remembered from the previous tuning parameters that had been remembered when you change bands/band segments. In other words, you only have to do an ATU TUNE once on each band segment (unless you change antennas). 73, Don W3FPR On 7/5/2018 3:54 PM, usmcss wrote: > Hey guys, > > Just got my KX2, I thought when you keyed the mic and the ATU was set to > Auto it would Tune the Antenna? > > I was just operating it and the swr meter was off the chart on 10 meters.

If you wish to change the filters later, you must remove the subRX (which is not as difficult as some would make it). As far as the AUX antenna, I would recommend that you install the BNC jack the the AUX antenna. If you want to later change it to operate with the SUB AUX input using the non-transmit antenna, that is easy to accomplish (just keep the TNC cable). Unless you select the AUX antenna for the SubRX, it will use the same antenna as the main RX through the 3dB splitter - so no confusion until you select the AUX antenna. 73, Don W3FPR On 7/5/2018 12:21 PM, Lee Murrah via Elecraft wrote: > I recently purchased the subreceiver for the K3S.

Keys for success: 1- Inside of housing must be designed to route any condensation away from the electronics. Design ENCOURAGES condensation on normally cooler enclosure surfaces, not the electronics. 2- A compartment heater (actually a high wattage, low value resistor) is ALWAYS energized to keep interior air temperature and temperature of electronic assemblies slightly above exterior. 3- Compartment must be absolutely air tight so as not to allow breathing as atmospheric pressure changes. Condensation that occurs collects on housing and drains to bottom of enclosure. If cooling is required, it must be done with heat exchanger to avoid ingress of outside air. BTW, mission critical equipment was housed in nitrogen purged compartments, including conduit which is major source of humid air flow! We required that equipment stored during construction must have compartment heaters energized. So, it can be done.

I have been running a remote station in Ontario for 15 years. The building is not heated or cooled at all. It has seen from 100F down to -20F without issue. The radios have been Kenwood TS480 to a Flex 6300 and during the time, the amps were either an SGC500 or a KPA500. The TS480 and the KPA500 come right online from the coldest days possible. One day it took 10 minutes of full power RTTY to get the amp temp to read above 0C (32F). That is how cold it was. The Flex 6300 is only engineered to 0F for the FPGA as it is not cold temperature hardened. My solution to that is that I don't turn off the Flex all winter as the FPGA generates enough heat (about 5 watts) to keep itself warm. The humidity ranges from 20% to 100% and it can change from that in weeks if not days. That past week it has been mid 90's and about the same in humidity. I have a few tower control boxes and for the most part, they are open at the bottom to let any moisture drain out should it happen to get inside as I have given up on total box waterproofing. I have seen too many equipment boxes flooded, so 1/16" holes seem to solve that. Fresh water does not hurt most electronics. Yes, those in Salt Water areas have bigger problems. I've taken a KX2 out of a car that was at -20C and used it (yes, the LCD was slow). That same KX2 has been taken from its pelican case at +35C and used it. It might have been a bit off frequency but I had no way of telling or hearing if it actually was. I have yet to have an issue in the past 15 years that I can relate to being in a non-environmentally controlled room. The same is true for our cars that see the same temperature extremes without issues (other than car batteries that fail). I take that back. On one car, my XM radio antenna would fail if it got too cold. Welcome to the Great White North! The short story is, the electronics we use today are well engineered and can handle temperature extremes and with a bit of ventilation help, they should work just fine.

Many hams use xlr connected microphones with phantom power. A w2ihy iBox and a cheap behringer mixer will quickly disprove your assertion.

My measurements indicate that the frequency drift now is approx. 50 Hz when the oscillator temperature increase from 25C to 52C. Most of the drift happens between 45C to 52C. As far as I can measure there is about 25 Hz hysteresis during cooling down from 52C to 38C (where the stand by temperature stabilize).

Yes, you may be able to get the mike to communications quality with racks of audio processing equipment etc., but you will probably spend more for all that when you add the cost of the mike, than radio costs by itself. Seem a tad wasteful to me when the radio already has a good EQ and a mike costing a fraction of the fancy "studio" mike will sound the same on the other end of the QSO. I don't under the fascination (or logic?) of using a wide response and expensive microphone just to narrow it down to 300 to 2800 Hz, unless you're H3LL bent on putting out a 10 kHz wide VOA grade signal that is frankly, illegal anyway. Yeah, yeah I know, you're voice is "different" and you need all that stuff to make it sound "right". If that's what you want, then by all means go for it. It's the same logic as using your (insert $200k car) to make daily commuter runs mostly stuck in traffic. 73, Charlie k3ICH From rich at wc3t.us Fri Jul 6 08:01:55 2018 From: rich at wc3t.us (rich hurd WC3T) Date: Fri, 6 Jul 2018 08:01:55 -0400 Subject: [Elecraft] KX2, is the ATU activated when you key the mic?

As you said though, bandwidth, etc., tend to make things sound different depending on who uploads. The real useful thing about the spectrograms are that they can be used as a site survey tool as well. The snapshot page was basically and offshoot of this page: https://www.nk7z.net/sdr-rfi-survey-p1/ which uses an SDRPlay RSP-1 as the SDR engine for a way to characterize, or survey your RFI environment. I ended up with a lot of spectrograms as a result of the site survey page, and it occurred to me they might be useful to others in IDing RFI...

Of course you can throw money at the problem by buying these products. A fool and his money are easily separated. :) Very good sounding mics built into gaming headsets like the Yamaha CM500 and a similar Koss model plug straight into the K3 and KX3 and sound great. I looked up this mic and tried to find specs. There's nothing there -- it's all silly putty.? Every place I looked said something different. :)? There's no response graph, not even a description of what connector is used and how it is wired!? Inside that mic is a cheap (maybe a buck) electret capsule. The shiny enclosure is simply designed to facilitate the separation process noted above. I'm retired from a career in pro audio, A Fellow of the Audio Engineering Society, and have a closet full of REAL pro mics that I use for recording music. The only one I'd consider using (and have used) for ham radio is an RE16, a variable-D dynamic with a good blast filter.? I used it because, at the time, I didn't have anything better, because the variable-D construction eliminates the LF boost of proximity effect, and, because it's a dynamic, all I had to do was solder up a cable to a connector that mated with the rig. List members K4TAX and W4TV are also retired broadcast engineers, and I'm sure there are others. 73, Jim K9YC From n8sbe at arrl.net Fri Jul 6 14:04:04 2018 From: n8sbe at arrl.net (Dave New, N8SBE) Date: Fri, 06 Jul 2018 11:04:04 -0700 Subject: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip Message-ID: <20180706110404.1fa1e31b6b6b329ecc65be958babcc1f.f5c901f203.wbe@email09.godaddy.com> From no9e at arrl.net Fri Jul 6 15:01:48 2018 From: no9e at arrl.net (Ignacy) Date: Fri, 6 Jul 2018 12:01:48 -0700 (MST) Subject: [Elecraft] Expert 1.3 to KX3 In-Reply-To: <1A408E40-3977-4917-9DA5-5A39CD79D16C@chopcat.co.uk> References: <5F1A671C-FE45-4F69-9C8E-C0CA42CEE3CE@chopcat.co.uk> <1A408E40-3977-4917-9DA5-5A39CD79D16C@chopcat.co.uk> Message-ID: <1530903708419-0.post@n2.nabble.com> I used KX3 + 1.3k with Dan's cables during expedition to CE0Y in CQ.

Saving someone $400 dollars is FRIENDLY ADVICE, not criticism. I took the trouble to search for a data sheet for the mic, found nothing that would even tell me what connector was used, what powering configuration it had, or how the mic was wired. Pro electret mics used a balanced form of powering called "phantom," and must work into a circuit that feeds + to both sides of a balanced output and negative to the shield. The electret mics used with unbalanced inputs get their bias in a very different way. The two systems are NOT compatible, and phantom power is built into preamps and mixers. W2IHY has built this into his 8-band equalizer. At $299, it's the lowest cost box I could find on his website that does it. AND -- if you have a K3, K3S, KX2, or KX3 there's a VERY good equalizer built in, so you're spending $299 plus shipping on the mic interface. Bottom line -- with these radios, you don't need anything that W2IHY sells. If you must use a pro (balanced) electret mic with ham gear, Radio Design Labs sells some relatively low cost mic preamps, but by the time you buy the preamp and the power supply(ies) you've spent some bucks there too. http://www.rdlnet.com/search.php?searchquery=mic+preamp But we don't know which powering interface the mic uses -- nothing I've found on the internet tells me. IF there is access to the capsule itself, it can be wired directly to the KX3 input. 73, Jim K9YC From k6dgw at foothill.net Fri Jul 6 17:10:58 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 6 Jul 2018 14:10:58 -0700 Subject: [Elecraft] help wiring a mic?

As I understand "symbol rate" it is the rate at which the signal changes from one symbol (BAUD) to another. What is not limited is the number of bits sent with each symbol. To present an example I hope never to see on the air, on 15M we are permitted to send digital data between 21.0 to 21.2 MHz. Someone could come up with a digital mode that used 200 KHz of bandwidth and use up all the digital allocation on 15M. It would have to remain within the symbol rate limitation, but it could send many bits with each symbol. The performance might be quite spectacular with the right choice of data rate, forward error correction, and error checking. The ARRL recommended to the FCC that modes be regulated by bandwidth, and not just the mode. The FCC said no. However, that kind of regulation would solve this problem. 73 Bill AE6JV On 7/6/18 at 2:10 PM, k6dgw at foothill.net (Fred Jensen) wrote: >A data transmission could occupy any BW so long as its symbol >rate remains at or below 300. ----------------------------------------------------------------------- Bill Frantz | "The only thing we have to | Periwinkle (408)356-8506 | fear is fear itself." - FDR | 16345 Englewood Ave www.pwpconsult.com | Inaugural address, 3/4/1933 | Los Gatos, CA 95032 From hayden.sean at gmail.com Fri Jul 6 18:07:53 2018 From: hayden.sean at gmail.com (Sean Hayden) Date: Fri, 6 Jul 2018 18:07:53 -0400 Subject: [Elecraft] VFO NR Message-ID: Hi all, I have a new to me KX3 that produces VFO dial noise on a few bands.

Look at the temperature rise during an FT8 transmission - it should be much smaller than your drift from 52C to 38C. The "cure" for temperature rise during transmit is to reduce the power output, or put an aftermarket heatsink on the KX3. 73, Don W3FPR On 7/6/2018 6:50 AM, Hans J Rasmusen OZ7BQ via Elecraft wrote: > Hello, > Thanks to Gary of Elecraft I have been able to perform the temperature compensation procedure on my KX3, sn 18xx.However, because it is a rather time consuming process, I would appreciate advice on when the compensation is good enough for FT8 on 6 meters? > My measurements indicate that the frequency drift now is approx. 50 Hz when the oscillator temperature increase from 25C to 52C.

I would find it very surprising that the FCC does not specify bandwidth limits on signal in the amateur bands, regardless of mode.

But here's the trick: hold the RATE(KHZ) button. It should unlock. Don't ask how I figured this out. I forget what all (and expect someone else on the list will fill in), but there were some updates made after those earlier serial numbers. I think some of those updates can be applied to the older models, but not sure if all can.

I didn't much care about 17 and 30 but 160 is my newest interest.

They were weak and in the noise, but I eked out a marginal contact.? Ten minutes later they were way out of the noise and I considered making an insurance contact but didn't want to get on their bad side, so I refrained.? A couple of days later on the 29th I thought I would get some insurance.? This time I worked them @0618Z which was their morning twilight.? The enhancement peak was amazing.? They boomed in for ten minutes or more and then started fading into my noise, but they were still readable when I believe they gave up.? My first QSO didn't show up in Clublog at first so I was glad for the insurance.? Later it did show up along with an extra one.? They show me making three Qs but I only made 2. Maybe they're making up for 20-meters where I called and they came back to N7WH.? I sent my call twice and he finally sent it correctly but must have left the log wrong.? So I worked them again.? I did also get them on 30 and after working them on 17 CW and SSB, I broke down and let my computer work them on FT8. Wes?

If you have the optional KXFL3 filter board installed, it can be the source of much of the tuning noise on the early serial number units.? A simple mod to the roofing filter board is described here: http://www.elecraft.com/manual/KX3%20Tuning%20Noise%20Mod%20rev%20B3.pdf I highly recommend that mod.? Before I did it, I could not hear any signals while tuning across the band on 28mhz and higher.? It is simple, and probably took me less than 15 minutes.?

Why not help him out so he can learn something. BTW, the KOSS SB40's are really bad. All bottom end and little highs. Maybe the 2 I have are defective. I have one of these mics and I use it for several uses, but I have also had it on my Flex and it sounds darn good and for the money while running SmartSDR remote and using PC Audio. I would recommend it for someone on a budget. I guess I'll have to wire it up for my KX2 and see how it works. There might not be enough BIAS voltage as other had suggested.

During this period of time changes that the Reflector has undergone have been significant as to how and when the Reflector is to be used. Long ago Eric set up a set of guidelines to keep the Reflector from becoming what other's have evolved into by some who don't appreciate what the Reflector was designed to do. They don't know how to follow simple guidelines or to focus on posted questions without expanding the matter into OT subjects. One stellar example is how a simple question by someone who really needs assistance quickly morphs out of control and rambles through 20 or more responses until Eric is required to intervene. The past week certainly has underscored how out of control the Reflector has become. In the future, should I require assistance, I will simply contact Elecraft directly. My appreciation to Eric and others who have tried to make this site something genuinely useful to Elecraft equipment users. No response is needed nor desired. Let this just stand as posted without comment.

Normally, my RT ping times to the station run around 30-50 ms and the latency is just barely apparent if I spin the Big Knob really fast.? It's really apparent if I listen off the air on a separate rig of course but I only do that if testing.? RT light time for geosynchronous satellites is in the 250 ms range to which you'd need to add any other I'net and terminal latency. I'd guess that some kinds of remote ops would work OK on some modes [CW/SSB ragchew maybe], but RTTY and digital modes and contest operation might be a real problem.? The most noticeable for an operator might be the display delay when tuning.? At any rate, I think it would be fairly non-optimal. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 7/7/2018 12:05 PM, John Perlick wrote: > Has anyone tried remote operation with a satellite internet connection?

I don't think you misunderstood anything but I don't know how you decided the signal is through the dummy load rather than coupling in the KAT500 from the antenna port to the dummy load port. I don't remember hearing local stations on the dummy load when using the Alpha Delta switch. I suppose the only way to get good isolation data will be to do a sweep of the KPA500 and Alpha Delta switch with the SA+TG. If I do that I'll share the results.

If you open the KAT500 box, you will find that lines between antenna ports and switch relay are close enough to cause inter-port cross-talk. I wanted to switch 3 antennas with KAT500 but decided not. instead, I connected antenna 1 to port A, dummy load to port B and antenna 2 to power C. This improves isolation between antenna 1 and 2. 73 de JH3SIF, Keith Kiichiro (Keith) Onishi Sent from iPad 2018/07/08 7:08?Fred Jensen ??????: > Andy, > > From your explanation, it sounds like you've switched the active KAT500 antenna port to a dummy load on which you're hearing a local 6m station.

You could get a rough idea by listening to the local and removing the antenna(s) from the KAT500 and maybe terminating the unused ports in a PL-259 with a 47 ohm resistor. I don't know if the unused ports are shorted or grounded by the relays, I never traced it out when I had my KAT500.? I did like the antenna selection capabilities however.

That sure beats the original geosynchronous latency of over 2 seconds, really testing the mettle of AT&T's echo suppressors. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From huntinhmb at coastside.net Sat Jul 7 20:30:13 2018 From: huntinhmb at coastside.net (Brian Hunt) Date: Sat, 7 Jul 2018 17:30:13 -0700 Subject: [Elecraft] [KX3] Incredible 6 meter opening right now -- Western U.S. In-Reply-To: <7F8BE723-F478-4A6D-AC24-343276EB15BD@n0xdw.net> References: <7F8BE723-F478-4A6D-AC24-343276EB15BD@n0xdw.net> Message-ID: Just worked N4SL (DN28) in MT on 50.145 SSB with my K3 @ 100w and a inverted V doublet - through 2 tuners, no less.

In my law firm, it was interesting to observe which people chose to broadcast negative departure emails. There are decent materials out there about how to depart a group, including how to send an email if you must. See, e.g., https://www.psychologytoday.com/us/blog/fulfillment-any-age/201705/seven-guidelines-making-great-goodbye Includes this quote among others: "Audiences expect, and therefore appreciate, your efforts to help them feel good about the person who?s leaving (or who has left) and about themselves." It's hard for me to imagine if the writer down below did not get some good things from this reflector over his seven year tenure, even if from time to time one must separate the wheat from some chaff. Which effort I usually find trivial and sometimes interesting and even productive in unintended ways (recent example being the thread on FT-8 which has been helpful to me in understanding not only the technology but also how people are reacting to it). FWIW, I think Eric and Elecraft have just the right touch running this reflector, and I appreciate what they do and all the excellent information that comes from it. Jim, N4TMM ------- Why do people leaving a list always have to announce it? To make sure everyone knows how good they are and how bad everyone else is that's left so that we can all feel bad? Sorry I don't, had nothing to do with why you left, your choice. Why not just unsubscribe without announcing it?

This is complicated and expensive. I would not expect to find it in a normal HF amateur transceiver, tuner, or amplifier. Maybe in some specialized equipment for multiradio operation, SO2R or otherwise. It is certainly something to be hoped for in future equipment. However, one should not be very confident that a switch with high isolation numbers would always prevent the sort of signal leakage mentioned in this thread. "Transmitting on a dummy load" is a common expression, but I guiess it is seldom representationve of what is actually going on. More likely, some signal is flowing as on the outside of shields, and needs common mode chokes for suppression. This point is well known to high-end competition stations that depend on separate receive antennas for the low bands. The job of such a receive antenna is generally not to pick up as strong as possible version of the wanted signal, but to pick up an adequate sampling of that signal along with less noise covering up that wanted signal. This involves avoiding noise pickup where the feedline runs through a high-noise environment (read: the shack building), as well as long distance signals coming in from the back of the receive antenna. (A conventional "front-to-back" number is not much help, one must rather use a complicated measure of back side rejection over all applicable "back" direction angles.) Noise pickup on the outside of coax will generally nullify the performance of a well-designed receive antenna that looks good on paper, unless the installation includes liberal common-mode choking and grounding of coax shields. I seem to remember one report that said the grounding was so critical that a ground connectied only to one side of the coax was markedly infererior to one that completely encircled the coax. Installations normally include running the coax through metal conduits, not just for mechanical protection, but for blocking noise pickup. If it is not already obvious to the reader, I am referencing noise pickup on receive antenna feedlines as something that corresponds to transmit capability as well, allowing transmission "on a dummy load" even if the dummy load is perfectly shielded. Bottom line: Leakage and crosstalk is a system characteristic that results from more than the performance of a given component such as a switch. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of ANDY DURBIN Sent: Saturday, July 07, 2018 3:54 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KAT500 antenna port isolation "I suppose the only way to get good isolation data will be to do a sweep of the KPA500 and Alpha Delta switch" Sorry - that should have read "I suppose the only way to get good isolation data will be to do a sweep of the KAT500 and Alpha Delta switch".

If it is possible. On my Elecraft K3S, sn 10715, the if gain, or better the FLx GN, was setted 0 for FL1 (2700hz-5 pole), 4 for FL2 (500hz-5 pole) and 8 for FL3 (200hz-5 pole). I read somewhere that it would be better 0 for wide filter, 2dB for medium filter, 4 dB for narrow filter. What is better Wayne? Can I use on my great K3S 0dB-2dB-4dB? Or you prefer other settings? C op 99% of time... Second and least question for Wayne. Sometime I like to use my old Cubic Astro 102BXA, yesterday on 10 meters, with a bug. How can be that this rig, 35 years old, have the best agc and a great qsk even for today standards? Lot better than every ja rigs, but even more pleasant to listen than today greatest rigs in the world (Elecraft obviously....)

First, I will say that I own both radios, so I'm not "drinking the Kool-Aid" for either one. I like them both and use them equally. The IC-7610 can be had now, even without the $200 "Dayton Discount" for about $3.2k A similarly equipped K3S even in kit form is well over $5k, including the P3/VGA required to make the proper comparison, but NOT counting any extra filters you may want. Please note, I am NOT arguing on the basis of ultimate performance, but simply cash outlay for similarly equipped radios. And yeah I know a TS-520 sounds great and will do all a casual op will need and, can be had for less than the "Dayton Discount" itself. I like the operating logistics of the Icom over the K3S, but the Elecraft works better AND has more features even though some are buried in multiple menus which is also a requirement due to the lack of panel space. Elecraft does the best to wring out multiple functions from one control....punch, hold to 1 sec, hold for 3 sec while standing on one foot etc..... Icom's touch screen really IS easy to like, even though I thought I'd hate it. Being a ?Centurion, these are probably the last radios I'll buy anyway, so WTH..... "Live long and prosper" as the saying goes. 73, Charlie k3ICH -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of N4OI - Ken Sent: Sunday, July 08, 2018 7:23 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S Comparison table finalized (link attached) Nice document.

The user should click on that to bring up the security panel for that file, then tell Norton to 'trust' it and undo what it did. The other option is if you can download the file and before Norton scans it (as in extracting from a zip), you right click on the file, go to the Norton file area and within that you can also tell Norton to ignore that file. Failing those, you can have someone email the file to you (zip) and tell Norton that it's allowed.

Define "more pleasant." Maybe you can post an audio recording made from the headphone jack with an isolation transformer so that we can hear what you're hearing. Have you tried changing the K3's AGC settings from the factory defaults to the values recommended here ? As for QSK, T/R turnaround time is probably better in the Swan rig because it doesn't have any digital signal processing, so no latency added, so no delays waiting for buffers to fill before the receiver hears signals between elements. But no DSP means limited noise reduction, limited notch controls, no adjustable noise blanker, etc. You can't have everything. 73, Bob, N6TV From n6tv at arrl.net Sun Jul 8 12:32:43 2018 From: n6tv at arrl.net (Bob Wilson, N6TV) Date: Sun, 8 Jul 2018 09:32:43 -0700 Subject: [Elecraft] OT: 7300 vs 7610 question In-Reply-To: References: Message-ID: Best place to post this question would be: https://groups.io/g/ic-7610 73, Bob, N6TV On Sun, Jul 8, 2018 at 8:06 AM, Bill wrote: > I know the 7300 is a simple rig with only a single antenna connector and > single RX.

(Likely Speaker) Then plug in the BT RXc - is the same output still listed and the headphone added, or did Speaker get replaced with Headphones? Some soundcards will not allow simultaneous Speaker and Headphone use. Usually when the front panel jacks are used, the rear jacks are turned off. WSJT-X does not use the soundcard path for TX enable, but the serial port connection. Apparently your BT RXc is turning off the audio to the K3 for some reason - this is a computer audio path problem, not a K3 problem. 73, Don W3FPR On 7/8/2018 12:35 PM, MaverickNH wrote: > Hi Joe, > > Yes, MIC SEL = Line In and I'm in DATA A.

One method for determining the proper gain to use is to use the gain metering in the K2 itself and a signal generator. You will be using AFV and dBV in the Alternate VFO B display. See page 38 of the K3S manual. Be sure to turn Tech Mode ON in the configuration menu. Turn AGC off and center the signal in the narrowest filter (in CW mode). Then go to the widest filter. (stay in CW mode) Set the audio gain for a comfortable level and look at the K3S AFV - wait until it settles. Do not readjust the AF gain until finished. Change the VFO B display to dBV - it should read zero dB. Now switch to FL2 and again note the dBV value - if it is also zero, you already have the correct FLx GN value set. If not zero, make note of the dBV value and do the same with FL3. Once you have the dBV readings from the procedure above, you may go into the CONFIG:TXx GN values up or down by the dBV values you measured. This procedure is indicated on page 40 of the K3S manual, but I believe I have provided more detail. For setting the AGC for your K3S, you might want to look at the information contained in the "Noisy K3" article on my website www.w3fpr.com. KE7X, Fred Cady also has some information on his website. 73, Don W3FPR On 7/8/2018 7:49 AM, IK4EWX wrote: > I need an info, and this time I thought "why not ask to the Elecraft nr.1 top > tech?" > If it is possible. > On my Elecraft K3S, sn 10715, the if gain, or better the FLx GN, was setted > 0 for FL1 (2700hz-5 pole), > 4 for FL2 (500hz-5 pole) and 8 for FL3 (200hz-5 pole). > I read somewhere that it would be better 0 for wide filter, 2dB for medium > filter, 4 dB for narrow filter. > What is better Wayne?

With Windows you *MUST* set up the sound cards before starting your apps (WSJTX and JT-Alert) as the sound card assignments change every time a sound card is added or removed. Your symptoms indicate that WSJTX is configured for the default audio device (or only audio device if the "BT RXr" is not connected). Connect all of your audio devices, configure the default output device with (Windows) Sounds -> Playback -> "BT RXr" as the default device (and default communications device). Configure the default input device with (Windows) Sounds -> Recording -> "Logitech mic" as the default device (and default communications device). Once the defaults are assigned - *without adding or removing audio* *devices*, start WSJTX, select File -> Settings -> Audio and make sure Input: "mic (USB Audio CODEC)" (Left) and Output: "speaker (USB Audio CODEC)" (Left). After that, start JT-Alert, Select Settings -> Manage Settings -> Sound Card and set "The Sound Card used to play the audio alert (wave) file to "[0] Windows Default Sound Card". If *at any time* you change the sound card(s) attached to your computer (including the K3S/K3 with KIO3B) you will need to close WSJTX and JT-Alert, reassign the default devices, restart the applications and reconfigure their audio devices. The devices *may* keep their (device numbers) assignments but they may not - and will *most certainly not* if the a new device has been added or a device has been removed. 73, ...

However, packets could still collide ...does the protocol handle this? Is there some sort of multiplexer available?" If only one device is doing the interrogating then there cannot be any conflict and there is nothing to multiplex. Typically the listening device will only need a 2 wire interface (TXD and GND). My KPA500 just listens to my TS-590 responses to Omni-Rig. Multiple receivers can listen to an RS-232 transmitter, just be careful not to try to make a TX talk to a TX and that may happen if you make a poor choice of Y cable. 73, Andy k3wyc From donwilh at embarqmail.com Sun Jul 8 16:37:42 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 8 Jul 2018 16:37:42 -0400 Subject: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied In-Reply-To: References: Message-ID: <6987944b-4a5f-af3b-bda3-b52c624e73db@embarqmail.com> Steve, Are you using the KXUSB to connect with the KXPA100/KX3, or are you using the KXSER with a real computer serial port or a USB to serial adapter? Since your magloop controller only 'sniffs', it means it should only listen and never try to transmit on the RS-232 signal lines. If it only listens, there will be no collisons (RS-232 is not packet oriented, but an asynchronous communications system). If the magloop controller also transmits on the RS-232 bus, you will need some external device to act as "traffic cop" - note that RS-232 is a point to point system (unlike Ethernet and others) where there is one driver device and one receiver at each end. So yes, you can use a splitter - one with a 3.5mm stereo plug and two 3.5mm stereo jacks if using the KXUSB. If you are using the KXSER cable instead, yes, you can connect a "Y" DB9 splitter to the DB9 end of the KXSER cable - the computer connects to one side and the magloop controller connects to the other side of the "Y".

I am using a KXUSB to the computer, with a KXSER cable going from the the antenna controller to the KXPA. It is the KXUSB that presently has no place to connect to. So - I think I can try a 3.5mm stereo y-junction at the KXPA. Hopefully impedances won't be an issue at 38400 baud... I did look for RS232 multiplexers - they seem to exist for industrial applications. The documentation seemed to be sparse on the web. Anyway - thanks for the pointer :) 73, Steve NU7B > On Jul 8, 2018, at 1:37 PM, Don Wilhelm wrote: > > Steve, > > Are you using the KXUSB to connect with the KXPA100/KX3, or are you using the KXSER with a real computer serial port or a USB to serial adapter? > > Since your magloop controller only 'sniffs', it means it should only listen and never try to transmit on the RS-232 signal lines.

If your magloop controller also attempts to transmit, you can remove the connection to pin 2 on the DE9 end of the KXSER cable (just remove the backshell and disconnect the wire). RS-232 multiplexors are complicated devices and require the use of the full RS-232 bus (mainly DTR and CTS signals) to handle the handshaking signals. The 3 conductor KX3/KXPA100 wiring will not provide the proper handshaking signals. The handshaking signals are not provided from the data stream (as they are in Ethernet and other communications protocols), but from the explicit signals separate from TXD and RTS. Note that the KX3 (and most other Elecraft products) rely only on TXD and RTS, which are reserved for data transmission only in the RS-232 scheme of things. 73, Don W3FPR On 7/8/2018 4:56 PM, Stephen Rector wrote: > Hi Don: > > Yes - it occurred to me after sending the post that I might be able to create the split at the KXPA with a stereo Y-cable/connector.

Anytime you add a soundcard, Windows will try to make that new one the default card. That means that system sounds will go out through that soundcard you just added. That goes for the internal USB AUDIO CODEC in the K3S or any other USB soundcard as well. So when adding any soundcard for digital modes, check to be certain it is NOT the default soundcard after it is installed. Windows does not know about those of us who use soundcards for purposes other than playing music and making the Windows Beeps. They assume that we are all consumers who want to listen to our music through the new soundcard - that serves the majority of their customers, but not those of us who have a different purpose. 73, Don W3FPR On 7/8/2018 3:35 PM, Joe Subich, W4TV wrote: > With Windows you *MUST* set up the sound cards before starting your > apps (WSJTX and JT-Alert) as the sound card assignments change every > time a sound card is added or removed. > From brian.waterworth at gmail.com Sun Jul 8 17:39:09 2018 From: brian.waterworth at gmail.com (Brian Waterworth) Date: Sun, 8 Jul 2018 17:39:09 -0400 Subject: [Elecraft] KX3/fldigi/USB sound card In-Reply-To: <763BA733-320E-48BA-A1E4-6E051D48D22F@wunderwood.org> References: <763BA733-320E-48BA-A1E4-6E051D48D22F@wunderwood.org> Message-ID: Kenny, do have the kx3 set for Data A?

It works well with the K2, K3/K3S, KX3 and KX2. Quite different than using the 'one transistor keying device' on the DTR or RTS signal lines. I use PTT via CAT command successfully on all my Elecraft rigs, and no other wiring is required. Yes, you can use VOX on the K3/K3S, KX3 and KX2. The VOX on the K2 will not provide reliable transmit triggering. 73, Don W3FPR On 7/8/2018 5:22 PM, Walter Underwood wrote: > You can use VOX instead of wiring up some sort of PTT or using CAT PTT. > From donwilh at embarqmail.com Sun Jul 8 17:50:53 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 8 Jul 2018 17:50:53 -0400 Subject: [Elecraft] KX3/fldigi/USB sound card In-Reply-To: References: <763BA733-320E-48BA-A1E4-6E051D48D22F@wunderwood.org> Message-ID: <94765d9a-3f51-8aa4-2bf2-fc292a3e588b@embarqmail.com> Brian, VFO Scanning should happen only if Scanning is turned on in the menu. That has nothing to do with the mode selection - scanning can take place in any mode. The main reason for using DATA A is that compression is set to zero, the equalization is set flat, and in the K3/K3S you can set MIC SEL to LINE without interfering with whatever you have set for SSB settings. 73, Don W3FPR On 7/8/2018 5:39 PM, Brian Waterworth wrote: > Kenny, do have the kx3 set for Data A?

Then, simply use a single "dit" (enable SSB+CW in the CW WGHT menu) to cause the amp to auto-tune on your current frequency. You can also issue a short vocal sound, and the amp will auto-tune. There are a few software packages that can listen to the K3 CAT frequency changes and send them to the amp, but I think they are more trouble than they are worth; it also requires a "special" serial cable. You should also set your K3 tune power to 15 watts which is what the 2000A expect if you wish to set a customize tuning solution for a particular band segment. That's all you need to be up and running. P.S. The new 2000A Remote Control Unit can connect directly to the K3 to listen for frequency changes and automatically retune the amp for the new band segment (no SW needed). --- Chuck, AE4CW -----Original Message----- From: William Liporace Sent: Sunday, July 08, 2018 02:13:PM To: Elecraft at mailman.qth.net Subject: [Elecraft] K3 -> Very Early Acom 2000A Hi Folks, I am looking for instructions of tips on how to hook up the very early Acom 2000A amps to my K3.

This is the only part of the table that seems a bit unfair to the IC-7610. I've added the missing parts with ">>>" (I hope this formats OK): *Features* *K3S* *IC-7610* *K3S Benefits* Spectrum + waterfall display area total 7.5? 5.5? More readable display >>> Display. res.

Marker pointing mechanism Dedicated knob Touch Accurate marker tuning >>> or >>> USB Mouse (Mouse more accurate) In sum, even using only part of the screen for the waterfall, the IC-7610 display may be able to use more horizontal pixels than the P3, so it can show more signal lines. But the Icom waterfall display doesn't scroll in Fixed mode (the VFO A cursor just goes off screen), which is a major flaw in Icom's design, not to mention the complex menu settings required to adjust the waterfall span and edges. Yes, the P3 dedicated knob + markers may be more accurate than touching the Icom screen, but using that tiny P3 knob is really much more difficult than clicking on a signal with an SDR, or just moving the VFO knob. However, the IC-7610 does let you connect a USB mouse. Then you just click on signals with the mouse pointer on the screen, so Icom wins on that. However, I'm told that the scroll wheel on the mouse doesn't "fine tune" the Icom VFO position after you click, so they really missed the boat on that one. Again I beg for the P3's USB connector to add mouse support. The hardware is all there. Left click: Move VFO A Right click: Move VFO B Scroll Wheel: Fine tune VFO A, B, or last-clicked (user option) 73, Bob, N6TV On Sun, Jul 8, 2018 at 4:22 AM, N4OI - Ken wrote: > Nice document.

I'm pretty sure you can just connect the Key Out jack on the K3 to the Key In jack on the 2000A, and the hard-coded transmit delay in the K3 (5ms?) will be adequate for the vacuum relay in the 2000A to switch. However, if you want to be 100% safe, or if you get key sequencing faults from the 2000A, you can use the 2000A key loop. This requires connecting the 2000A Key Out jack to the K3 TX INH pin (pin 7) on the Acc jack. Since the 2000A pulls Key Out low when it's OK to transmit, you need to pull pin 7 on the K3 ACC jack up to 5VDC (max) with a 10K resistor. To do that, you'll have to run a line over to the K3 12VDC jack and use a resistor divider or a transistor circuit to drop it down to 5VDC (the latter is how I did it.) I've seen a diagram where someone got the 5VDC pullup voltage by shorting pin 1 to pin 7 on the Acc jack. Pin 1 is the FSK input, which is pulled up to 5VDC. I don't know if this works, but it's simpler than what I described above. I'm pretty sure it means you can't use the FSK input. Once you get the hardware connected, go into Config:TX INH and set INH = Hi. You'll need to be in tech mode to do this. Hope this helps. 73.

As someone has mentioned, you do not want to have two devices driving a data signal simultaneously. At some point one will go to +12V, the other to -12V. They will argue and one will win, the other will cease to function. We were very careful when designing the devices that need to ?sniff? the RS-232 cable. The KRC2 has an internal multiplexer that allows it to share driving the signal to the radio in parallel to the one from the computer. Even still, we advice folks to set one or the other for sending commands to the radio. The KPA500 has an internal relay to enable or disable the data being sent out the PC port. this is controlled by the menu system, allowing the KPA to perform serial polling (PC port TxD will be enabled) or pure sniffing (TxD disabled). Note that enabling both devices (computer and antenna controller) to poll the radio can be problematic, even with a multiplexing device. There are some PC applications that can be greatly surprised if they receive a response they didn?t specifically ask for. The surprise generally ends in a crash. Most programs have been rewritten to accept whatever comes there way. I won?t embarrass the problematic program?s authors, but they are aware. There is one other thing to consider. If you always use the radio and magloop with the computer running, then you are fine. But at some point if you don?t want to use the radio then you will need a source to poll the data. In that case just set the radio to output changes as they occur. That should do the job quite nicely, keeping the magloop controller happy with more data than probably needs to get the job done. 73, Jack, W6FB > On Jul 8, 2018, at 2:00 PM, Stephen Rector via Elecraft wrote: > > Hi Dick: > > Thanks - the diagram makes things very clear.

Why? The big weight (power toroid) is on the left side, while the heat generators (the PA transistors) are on the right. The center of gravity would be lower, cables would be down low (especially the power cable), and the fans up high. The only heat generators on the left side are the power regulators (for +5 and +12V). They don?t generate nearly as much heat as the PA. The down side? The carry handle is on the left. That?s why a short cradle would be needed to lift the case above the handle extension. Just opinion, not an official recommendation. Mine sits nicely on its bottom feet with the KAT500 on top. That allows me to cable the two very nicely using custom cables. 73, Jack, W6FB > On Jul 8, 2018, at 8:25 PM, Jeff Blaine wrote: > > To clarify - by "side" i mean the side that you would call the left or right side of the case - that is what i'm considering to have down.

Alas, on transmit the 2-meter transverter generates a LOT of heat, very quickly, even at quite modest power levels (e.g. 0.5 watts). Trying to attenuate some of that heat, I bought Fred Meier?s, VE7FMN, Cooler KX Plus heatsink. Fred?s aftermarket design is very well-done and he inlcudes very nice stainless steel fasteners. I have an early-2017-build KX3 (serial number 9428; factory assembled) which includes the upgraded factory heatsink. Apparently, this heatsink is bonded to the case with an adhesive in addition to the four fasteners. Normally one would apply heat to soften such an adhesive. Albeit, great care is needed to ensure internal components are not damaged. Reasoning that the KX3 folds back power at ~60C, I set that as my upper limit. Using a portable dryer and a Fluke IR temperature meter I brought the stock heatsink to just under 60C/140F. Still no-go. The stock heatsink will not budge. I expect I could pry the stock heatsink off using a flat-bladed screwdriver, if I were willing to mar the case of my KX3. But not damaging the radio remains the overarching priority. Any suggestions? 73, Jeff K4YWZ From fcady at montana.edu Mon Jul 9 11:07:13 2018 From: fcady at montana.edu (Cady, Fred) Date: Mon, 9 Jul 2018 15:07:13 +0000 Subject: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied In-Reply-To: References: , Message-ID: Thanks Don. It must have been interesting working all that out. I used to enjoy giving my students a history lesson explaining the control and handshaking signals in the RS232 connector from basic principles, starting with the Bell 103 modem. That didn't help explain the terminology and signal naming problem that Andy had. Manufacturers were terrible at keeping to the standard. And really, in isolation, it doesn't make sense that a signal named TxD would be a input and not an output. Documentation was scanty and so the scope, or my favorite test tool -- the RS232 Blinky Box -- had to be gotten out to tell what was what. The now used for other purposes signals are: DTR -- from the terminal to the modem to tell the modem the Data Terminal was ready. Now used for CW or PTT. DSR -- From the modem to the terminal to indicate the modem was ready (generally power on). The Bell 103 could send data only in one direction at a time so RTS and CTS were included to control the flow of the data. RTS -- Request to Send from the terminal to the modem to request the line. CTS -- Clear to send from the modem to the terminal to say the line was not busy and to go ahead with sending the data. RTS and CTS were also used to control the data flow from a fast device to a slow device. I think there were some kenwood radios that used this scheme. DCD -- Data Carrier Detected was used for the modem to tell the terminal that the carrier from the other data set was being generated (the phone line was working). RI -- Ring Indicator asserted by the modem when it heard a ringing signal at the other end of the telephone line. As I remember it.

We used Bell 103 protocol modems to provide full duplex connections for our users who were using ASCII terminals, both CRT and teleprinter. They could type at the same time the computer was sending data, so the modem was supporting full duplex. I note the Wikipedia article mentions: "The Bell 103 modem used audio frequency-shift keying to encode data. Different pairs of audio frequencies were used by each station: The originating station used a mark tone of 1,270 Hz and a space tone of 1,070 Hz. The answering station used a mark tone of 2,225 Hz and a space tone of 2,025 Hz." So the modem can both send and receive at the same time if the communication link supports it. Other terminals, such as the IBM 2741, could only handle data in one direction and needed the RTS/CTS lines to support their needs. And, radio applications would need separate transmit frequencies and good filtering to support full duplex. 73 Bill AE6JV On 7/9/18 at 8:07 AM, fcady at montana.edu (Cady, Fred) wrote: >The Bell 103 could send data only in one direction at a time so >RTS and CTS were included to control the flow of the data. --------------------------------------------------------------------------- Bill Frantz | Re: Computer reliability, performance, and security: 408-356-8506 | The guy who *is* wearing a parachute is *not* the www.pwpconsult.com | first to reach the ground. - Terence Kelly From k6xk at ncn.net Mon Jul 9 12:43:33 2018 From: k6xk at ncn.net (Roy Koeppe) Date: Mon, 9 Jul 2018 11:43:33 -0500 Subject: [Elecraft] Breakers for KPA1500?

For shorter runs it's fine. But measure the run length, multiply by 2 (two wires) and calculate IR voltage drop. It's not a big expense when you're installing to use 10 instead of 12 awg if it would make a noticeable difference. Seems like it wouldn't need to be said... but never let them cheap out and use aluminum wire. I actually had an electrician try that for a bigger gauge run. Fortunately I noticed before it was enclosed.

I know that there are feet are on the right side of the case, but if I were to place the KPA500 on its side, i think I would create a stand so that it can sit on the left side. Why? The big weight (power toroid) is on the left side, while the heat generators (the PA transistors) are on the right. The center of gravity would be lower, cables would be down low (especially the power cable), and the fans up high. The only heat generators on the left side are the power regulators (for +5 and +12V). They don?t generate nearly as much heat as the PA. The down side? The carry handle is on the left. That?s why a short cradle would be needed to lift the case above the handle extension. Just opinion, not an official recommendation. Mine sits nicely on its bottom feet with the KAT500 on top. That allows me to cable the two very nicely using custom cables. 73, Jack, W6FB > On Jul 8, 2018, at 8:25 PM, Jeff Blaine wrote: > > To clarify - by "side" i mean the side that you would call the left or right side of the case - that is what i'm considering to have down.

When developing the KPA500, we went back and forth as to which was the best side, so my memory can be a bit fuzzy there. Mine had no handle or side feet for quite a while. There is still significant heat production on the left side since the side panel is used as a heat sink for three (I believe) TO-220 regulators. I would still get that up off carpet so that at least some air can flow through to dissipate the heat. 73!

Other codes around the world are similar. For example, if you use AWG 12 Type UF cable, the base rating is 20 Amps. With the temperatures we have in Arizona, where it can get above 140F in an attic, they have a correction factor of 0.71 if the wire is rated to 90C. So it should only be used up to 14.2 Amps. If you are installing from scratch, I would go to AWG 10 just for a safety factor. Of course, you may not be here in Arizona. It actually may get hotter than that here in some attics. You can read the NEC for free by going here and signing up. It will tell you more than you want to know, in excruciating detail.

For shorter runs it's fine. But measure the run length, multiply by 2 (two wires) and calculate IR voltage drop. Actually, the voltage drop is greater than you calculate with the simple formula because current to electronic loads is not a sine wave!? This makes Josh's advice even better!? There's a technical discussion of this in? http://k9yc.com/GroundingAndAudio.pdf beginning around slide #56. > It's not a big expense when you're installing to use 10 instead of 12 awg if it would make a noticeable difference. Yes. The cost of that outlet is mainly labor. I would even consider #10 small if it's a very long run, and consider #8. And our advice is not specific to the KPA1500 -- it would be the same for any big electrical load. 73, Jim K9YC From jim at audiosystemsgroup.com Mon Jul 9 20:40:29 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 9 Jul 2018 17:40:29 -0700 Subject: [Elecraft] Breakers for KPA1500?

In my grad school days, I was a mentor to a HS kid whose dad was an insurance company safety engineer in the pre-OSHA days and later became a state-OSHA manager. I will always remember him saying that if a local inspector finds a safety violation, he will give you 30, 60, or even 90 days to correct it, but if the insurance company inspector finds the violation, they can impose a 24 or 48 hour deadline or the coverage will be suspended. I can believe that! The kid, BTW, did become a ham after finishing law school but passed away a few years ago. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From perry at spotlightdisplays.com Mon Jul 9 22:53:38 2018 From: perry at spotlightdisplays.com (usmcss) Date: Mon, 9 Jul 2018 19:53:38 -0700 (MST) Subject: [Elecraft] Ext Mic Displayed on kx2 screen?

This is a great (IMHO) way to keep track of firmware changes. I can carry all the annotated manuals with me during portable/mobile expeditions for the eventuality of a memory failure (mine, not the rigs'). It also saves a lot of trees. I always know where to find my PDF copies and really dislike most paperwork, except for the awesome KE7X books. I tried doing this with the IC-7610 manual, but it was not allowed. I would add this to the K3s vs. IC-7610 comparison chart as an Elecraft benefit. BTW, I have the 7610 manual to help a friend who bought one. His radio is back at Icom for what seems to be a common failure mode--suddenly no TX or RX. He would not drink the Elecraft Kool-Aid I tried to provide, even though he's operated many a K3 at FD or contest sites with me. 73, Bill, K8TE (catching up on e-mail) I download all the Elecraft manuals and print them on 3-hole paper (pre-punched) and then keep them in a binder. This way, I can add notes here and there in the right spot merely by inserting another 3-hole punched paper or punching printed e-mails or something myself. I think this is the absolute best way to manage the information you will collect over the years on different things like suggested settings for this-and-that and so on. 73, phil, K7PEH -- Sent from: http://elecraft.365791.n2.nabble.com/ From jim at audiosystemsgroup.com Tue Jul 10 03:10:01 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 10 Jul 2018 00:10:01 -0700 Subject: [Elecraft] KAT500 antenna port isolation In-Reply-To: <2EDBA00C-EE15-4768-97DB-567035399FC5@blomand.net> References: <025f01d41657$afd429f0$0f7c7dd0$@cox.net> <1531188727791-0.post@n2.nabble.com> <2EDBA00C-EE15-4768-97DB-567035399FC5@blomand.net> Message-ID: <9330eff2-5b7a-ea69-72e3-6b401684d201@audiosystemsgroup.com> Yep.? When you're trying to get 50-60 dB down, EVERYTHING has to be done very well. Several years ago, I was not achieving the harmonic suppression I thought I should, so I bought a spool of BuryFlex (RG8 with a robust copper braid shield) and replaced every piece of coax inside my shack. I didn't measure the result (not easy to do), but suppression was 10-15 dB better.? Another important component of minimizing crosstalk is having a good ferrite choke at the feedpoint of every antenna. 73, Jim K9YC On 7/9/2018 8:19 PM, Bob McGraw K4TAX wrote: > All this doesn't speak well for the quality of the dummy load or coax jumpers. > > Bob, K4TAX > > > Sent from my iPhone > >> On Jul 9, 2018, at 10:01 PM, Phil Kane wrote: >> >>> On 7/9/2018 7:12 PM, K8TE wrote: >>> >>> BTW, I have made a 75m QSO on a dummy load.

Some earlier KPA500s had a problem on 12 meters. Elecraft came out with a mod you could perform yourself or send the amp in and they would do it for you for free except you had to pay the shipping. You didn't have to send the whole amp back. Just the RF module. I have KPA500 serial #1523 and sent the RF module to Elecraft in July of 2014. It cost me $15.00 to ship the module. The invoice shows one hour of labor at $99.00, but no charge to me. They shipped it back to me at their expense. I don't know if it was Elecraft policy to do the mod for free for everyone. My amp was one of the T33A DXpedition amps. On the invoice it says T33A amp upgrade. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of David F.

While it will work if you use the ground wire as the neutral conductor, it is a severe violation of code to do so, and it is highly dangerous from a safety standpoint. The KPA1500 is a pluggable device, not a hard-wired device (unlike a range or a full house air conditioner). In fact for wiring our air conditioner compressor, I ran 3 wires plus ground (because that is what I had on hand), and the inspector required that the 3rd conductor NOT be connected to anything, so it works both ways. The way I see it: If the device is permanently wired in, 2 wires and ground is desired and sufficient. If the device plugs into a receptacle with the possibility of adding a 120 volt receptacle from that wiring box, run 3 wires plus ground. The neutral wire will be left unused unless a 4 wire receptacle or a 3 wire receptacle AND one or more 120 volt receptacles are added to the box in the wall. 73, Don W3FPR.

In that case, his other ham equipment would presumably run on older 120V wiring.

However, as has been pointed out, ham equipment doesn't constitute that much of a load, even for a station at full legal power.

If you own a Palstar AT-AUTO you need to remember that the RS-232 cable (null modem) originally supplied with the tuner is cross-wired (pin 2 to pin 3, and pin 3 to pin 2).? This is the correct wiring that allows the tuner to follow frequency excursions by the K3. Recently I returned my K3 (sn 21) to Watsonville for hardware upgrades that included replacing the KIO3A board with the new KIO3B board (now standard on the K3S).? However, this new board no longer utilizes a DB-9 connector for RS-232 functions, but instead uses a female RJ-45 socket for RS-232 functions.? This now renders obsolete the original DB9-equipped cable that came with the AT-AUTO.? Fortunately, Elecraft includes with the upgraded KIO3B board a pre-wired 30-inch RS-232 cable.? This cable has an RJ-45 plug on one end and a DE9S plug on the other end.? Unfortunately, this cable is wired straight-through . . . no cross-wiring . . . which means no QSY following by the Palstar. After spending more time than I care to admit in testing cable continuity, serial baud settings, and configuration menus in both the K3 and the Palstar, I suddenly tumbled to the fact that the Palstar cable is cross-wired while the Elecraft cable is not. Home-brewing a new cable with the proper wiring now permits the AT-AUTO to follow band and frequency changes in the K3. Unfortunately, the Elecraft cable uses molded connectors which prevented an easy and quick fix. Just a tip for those who own either the original Palstar AT-AUTO or the newer HF-AUTO (which I presume is wired the same), or for anyone using RS-232 peripheral devices who want to upgrade to the new KIO3B board.? Those pin-outs in the manuals are there for a reason! 73, Kent Trimble, K9ZTV Jefferson City, Missouri From john at kk9a.com Tue Jul 10 12:13:31 2018 From: john at kk9a.com (john at kk9a.com) Date: Tue, 10 Jul 2018 12:13:31 -0400 Subject: [Elecraft] Breakers for KPA1500?

Yes you can run three conductor Romex and have a 120v and 240v outlet but I do not see this as a good plan as it could easily exceed 20 amps on one leg. Upgrading to higher amperage circuit and you'll exceed the amperage rating for a standard 120v outlet. Two separate circuits are much easier to manage. John KK9A Don Wilhelm W3FPR wrote: Tony, While it is possible and safe to use only two wires plug safety ground (Green Wire Ground) for a 240 volt receptacle or 240 volt only device (in-home air conditioner, dryer, etc), it is quite unsafe to split off for a 120 volt supply using one hot and ground - in that case (such as a range that has a 120 volt outlet on it or a 120 volt fan) you MUST run 3 conductors plus ground. The ground wire should never carry current.

If you pay an electrician to do the work, the difference won't be 10% of the bill. If you do it yourself, following code and getting it signed off by an electrician and inspected of course so your insurance won't deny coverage, and you value your time, and there is a chance you may want extra 120 V in the future, it will save hours of replacing it later. I would go with the 10/3 with ground, but that's just me. When you sell your house and the next owner wants to put something else there, you may get more for the property. For example, the previous owner of our house installed a 20A RV power outlet. And yes, it came from one side of a 20A 240V feed with a neutral and ground. That was worth hundreds more to us. I would still put in 20A breakers. They protect the wires and if all you need is 20A for the load, it seems sensible to be more protective. I have heard of inspectors seeing 20A breakers and AWG10 wire and questioning it, but it seems you could explain it was done for an extra safety factor, etc. Breakers are quick to change. Good luck with whatever you do. 73, Mark W7MLG From jeff at kc9wsj.us Tue Jul 10 12:47:06 2018 From: jeff at kc9wsj.us (Jeff KC9WSJ) Date: Tue, 10 Jul 2018 11:47:06 -0500 Subject: [Elecraft] W2 wattmeter maximum Cat5 cable length In-Reply-To: <02B318D7-B821-4103-8466-0EA715C3CEAA@gmail.com> References: <02B318D7-B821-4103-8466-0EA715C3CEAA@gmail.com> Message-ID: <1531241226.28962.2.camel@kc9wsj.us> the standard cable is not Cat5, it's just a ribbon cable with RJ45's (I think?) at each end.

It's hard to imagine how 20A on a 240V circuit split to 120V outlets (with neutral) could be exceeded in a single operator ham station running legal power, and powering only ham gear from that circuit. Let's say that the power amp is drawing 15A keydown. That's 3.6kW, and you still have 5A at 120V on each of the two legs. Now, let's say that you have an Astron 14.4V supply running on one of those outlets powering a tranceiver, even two or three tranceivers, only one of them TX at a time. I find it hard to believe that the Astron draws more than 3A, probably less. Add an old big iron computer to the other leg, maybe 1A on that leg. Indeed, a second power amp could be running off that circuit as long as only one is in TX mode at a time! 73, Jim K9YC From n8sbe at arrl.net Tue Jul 10 13:20:38 2018 From: n8sbe at arrl.net (Dave New, N8SBE) Date: Tue, 10 Jul 2018 10:20:38 -0700 Subject: [Elecraft] =?utf-8?q?Ext_Mic_Displayed_on_kx2_screen=3F?= Message-ID: <20180710102038.1fa1e31b6b6b329ecc65be958babcc1f.e02b5eaa98.wbe@email09.godaddy.com> From john at kk9a.com Tue Jul 10 13:34:42 2018 From: john at kk9a.com (john at kk9a.com) Date: Tue, 10 Jul 2018 13:34:42 -0400 Subject: [Elecraft] Breakers for KPA1500?

However, the VFO B encoder is defective. It has lost the push-in switch functionality. So, I need to replace it. If you've replaced one of the encoders, how harry is the process? I built my KPA500 and am relatively competent with a soldering iron, having replaced SMD diodes and transistor on occasion, but I'd hesitate with my oldish eyes to want to do much more than that.

If you can find someone who previously added the KAT100 and KPA100 to an EC2 enclosure, they might have the leftover front and rear and top panels. You can supplement those parts with K2 side panels and front bottom cover and 2D connectors and chassis screws to create a very near equal of an EC2 enclosure. 73, Don W3FPR On 7/10/2018 12:09 PM, Curt Nixon wrote: > Good Morning All: > > Does anyone know if the EC-2 project cabinet is still available??

First real info I've gotten. I said Cat5 because the documentation mentions it and I believe it says you can use a standard Ethernet cable. I haven't taken a close look at the coupler circuitry. If it's like most remote couplers I've seen, a too-long cable can cause a drop in the DC voltages that carry the forward and reflected power signals. If the coupler does a conversion to digital, then the cable length wouldn't be an issue.

A couple of years ago I called my home owners insurance company, USAA, and told the nice young lady who answered the phone that I thought building permit fees were just another tax and asked her if it would be acceptable to the insurance company if I hired contractors for the electrical, plumbing, heating, etc. work and specified in the contracts that all work would be performed to currant code. Her response was that they really did not care what I did unless there was a catastrophe. In which case if the cause of the catastrophe was traced to uninspected work, I was not insured. Not sure if this is still the case, but a few years ago the Trustees of the Town of Deertrail, Colorado put in place a system where a person could bring a description or sketch of proposed work written on anything, including a bar napkin from the VFW hall, to the Town Clerks office and be issued a building permit. For a fee of $2.00 you could have the work inspected by the Mayor/Building inspector when he was in town, since he was a long haul trucker he was frequently on the road but would do the inspection when he got back. Since most jurisdictions are more formal than Deertrail, I would recommend talking with the people in your local jurisdiction to learn the local requirements. Or as my Business Law professor said, "The expensive professional advice is always cheaper than fixing the problem(s) we create by not knowing the rules and regulations."

The twist action in CAT-5 does not help here at all. The things to watch for are signal loss due to resistance (shouldn?t be too bad, depending on the wire and length), and RF pickup. The latter can lead to bad and erratic readings. The best advice is to keep the cable as short as possible. 73, Jack, W6FB > On Jul 10, 2018, at 12:06 PM, Dick Green WC1M wrote: > > Thanks.

If it's like most remote couplers I've seen, a too-long cable can cause a drop in the DC voltages that carry the forward and reflected power signals. If the coupler does a conversion to digital, then the cable length wouldn't be an issue.

The breaker you install has nothing whatsoever to do with the equipment your going to use on that circuit. The breaker is chosen for the size of the wire you run in the walls. PERIOD!!! The amp is protected by the fuses in the amp! Not the circuit breaker. The only thing protected by the breaker is the wire use in that circuit. If you have a 50amp 240 v circuit, FINE! The amp will use what it needs. The fuses will protect it from overdraw of current. The circuit breaker will protect the wire to the receptacle. PERIOD! If you don?t know this you should hire an electrician. PERIOD! Talk about a thread that?s gone on too long!

I?m using the mic that came with the radio. It does have the buttons. Another thing that is happening is that the frequency is jumping sometimes by 1 kHz, I thought I was bumping the dial but that?s not the case, I was watching the screen and the frequency jumped and I was no where near the dial. And I?m not hitting the top buttons ether.

Suggested max from 51 - 51 MHz, 85 W,? 52 - 54 MHz 70 W. " ?? There are other specs related to K3S/10 and transverter outputs. Looks like 100 watts is a good number from 50 - 51 MHz. ? I see that on my radio and I've not checked power above 51 MHz.?? The internal tuner operates at around 5 to 7 watts output while resolving a match.? Using the internal tuner seems to tell me the external devices are not operating with a 50 ohm nonreactive load attached.? In that case, being voltage sensing devices, the load will affect the power indications. The point which would concern me most is having 3 different power measuring devices which give significantly different values. 73 Bob, K4TAX On 7/10/2018 10:26 PM, Nr4c wrote: > Did you check the specs?

Several companies make and/or sell multi-outlet strips for Power Pole connectors, and also sell Power Pole connectors. Many of us have standardized them for all of our DC powered gear. Once you've learned how, they're easy to install with nothing more than hand tools and a soldering iron.

And what I am referring to is the RF Meter, not a watt meter. The crazy thing is it only happens on 10 meters. When I have the radio set to 10 Watts and key the Mic, the RF Meter will not move when I talk. If I set the watts to 9.6 the RF Meter moves every time I talk. If I go to 20 meters the RF Meter will move on all watt setting when I talk. It only happens on 10 meters. If anyone out there has a Kx2 and can set there watts to 10 and transmit on 10 meters and let me know if your RF meter moves to your voice I would appreciate it. Also power might be the issue so if you have batteries please use battery power. My battery power is 12.4 when I try and transmit.

I chopped the wall wart power supply cables and used them for the interconnection between the equipment and my power box.?? Easy to add items, and easy to remove items.??? No wall warts at my QTH. While the distribution panels are nice, although a tad expensive in my thinking, and they generally limit me to one type of connector.? Also they are "rated" for much higher current.? In that regard, I would NEVER use one of these to power the transceivers.? The transceivers all connect direct to the station power supply.??? Reason:? more connectors in the path = more IR loss. 73 Bob, K4TAX On 7/12/2018 7:03 AM, john at kk9a.com wrote: > Probably the only commercial option is a Powerwerx distribution panel. > Then you will need cables with a round connector on one end and a > Powerwerx on the other.

Flush trim (diagonal cutters will not suffice) the leads on the encoder board and also the area of the Control Board which possibly could contact it. If you do not have flush cutters, you can find inexpensive ones in the tool section of your local Home Depot store. Look for Lufkin or Xcelite or Cooper (all the same company) "shear" cutters - they are inexpensive and will do a good job. As added insurance, you can place a piece of card stock (a business card) or better yet Fish Paper or a flat piece of thin plastic like that used for the shrink wrap on purchased small items between the encoder board and the back of the control board. 73, Don W3FPR On 7/12/2018 3:22 PM, Don Schroder wrote: > Hi all, > > I am very happy with my K2 kit.

In-Reply-To: References: Message-ID: <5f9198e8-d8fa-0c20-5255-ad08545186cd@embarqmail.com> David, J3+ is the power supply voltage. Make certain the APP connectors (both on the KPA100 and the Power cable) are correct. Look at the end of the connector - you should see only the contact blade. If you can see the spring finger that is under the contact blade, the contact blade is not inserted far enough. Measure the voltage at the end of your power cable - it should be 13.8 volts or higher (up to 15 volts is OK). If not, check your power supply or the power cable. Make sure all connections to the power supply are tight, and that the fuseholder on the power cable is assembled correctly. The free side of the fuseholder should slide freely along the red wire. If not, there may be a lack of contact with the fuse. You can also check with your ohmmeter to be certain the J3+ line is not shorted to ground. 73, Don W3FPR On 7/12/2018 9:13 PM, David Dawson wrote: > Hi to all, > Just put together the KPA100, and did the initial voltage tests while connected to the K2.

Back in those days we waited six months for the FCC examiner to come to town.? I sent my application to the FCC in DC, who in turn sent it to Long Beach, CA from whence the examiners came.? So the FCC had two chances to check the application before I took the exam.? I had requested three calls, W7WS, K7WS and N7WS.? I passed the exam and the paperwork went off again. Imagine my surprise when the application was returned to me because they didn't like the way I had signed it and wanted me to do it again.? In red pencil, the calls W7WS and K7WS and been lined out and N7WS circled in red.? Clearly, that was to be my call.? Unfortunately, when my Extra Class license appeared it was issued under my original call.? The vanity program of the day was just about to end and I assumed that during the delay "my" call had been issued to someone else and I was going to be out of luck. I fired off a letter to my US Senator, who happened to be K7UGA, requesting help.? I got a letter back suggesting that if I simply reapplied for the vanity call, he was "pretty sure" that I would get the call. Of course, I did. Wes? N7WS ?ps.? During the Memorial Day holiday week, I got to operate K7UGA, which is club call for the CADXA, on the 20th anniversary of his passing. ?On 7/13/2018 10:27 AM, ANDY DURBIN wrote: > "I want to learn about vanity call signs, why would I want one?

What do they represent?" A vanity call is one that is self selected rather than being the next in order assigned by FCC. The main reason for getting one is ....vanity. Many select a vanity call that represents their name or initials. Some because the call comes close to spelling a word that has significance for them. Some because it represents an area of interest. In my case I was assigned G3WYC by UK GPO back in 1967. I chose the vanity call K3WYC when I became licensed in USA. 73, Andy k3wyc ______________________________________________________________ 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 k4ar at comcast.net From edauer at law.du.edu Fri Jul 13 18:35:20 2018 From: edauer at law.du.edu (Dauer, Edward) Date: Fri, 13 Jul 2018 22:35:20 +0000 Subject: [Elecraft] Vanity call question Message-ID: <4834D789-E6EE-44FF-A2FA-E921ECE5B222@law.du.edu> KN1CBR was issued as my Novice call in 1957.

KDKA, KQV and KYW in Pennsylvania and KFIZ in Wisconsin were licensed before 1922. KFNS, KFTK, KGSM and KQQZ in Illinois and KWAM in Tennessee were originally licensed west of the Mississippi and moved a few miles east of the Mississippi but serve markets that are mostly west of the Mississippi. KJWP was originally licensed in Wyoming and moved to Delaware. KTGG in Michigan was probably issued by mistake in 1985... At least 20 stations with callsigns beginning with W are located west of the Mississippi, but that's another story altogether... 73 Frank W3LPL ----- Original Message ----- From: "Ken G Kopp" To: "Elecraft" Sent: Friday, July 13, 2018 9:58:26 PM Subject: [Elecraft] OT: Call location Trivia:.

Yes, I had turned the tuner while measuring the voltage, it did not change the voltage. So I took it all apart again and went over the Panel & Control boards with a magnifier and pick. Didn?t even heat up the soldering iron, just examined. Results? The tuner NOW moves the frequency, but not ALWAYS, just most of the time. Biggest problem now is, the tuner moves the frequency ONLY DOWN, even when turning it clockwise! (Which I assume should RAISE the frequency). With sporadic tuning (most of the time down, sometimes no change), and only going down and rarely up, I wonder if this is a result of a loose component or loose pin? I think my next move will be to retouch pins with a hot iron, and see what change that brings. Am I moving forward, or spinning my wheels? Thanks for your input! It IS greatly appreciated!

They pay the fee. My XYL Rose took Her Dads call [ W9DHD] after She passed the General test. I remember it being rare to hear a W 1 x2 and a K 1 x 2 was extremely rare.

I?ve had 7 call signs since 1959, moving around relatively frequently while the Call District still meant something. For a while, I thought about getting my first non-novice callsign (K5VCM) back, but passed on that. And then discovered that W5GY was available, and ended up passing on that, too, after looking around the shack and seeing in how many places my last and longest-held callsign was imbedded. By then I?d had it for around 30 years. Just passed on the whole thing ? :-) Grant NQ5T K3 #2091, KX3 #8342 > On Jul 13, 2018, at 9:59 PM, Pete Lascell wrote: > > I have known the previous and current YL's who have had W0MAN > > Pete W4WWQ > > ______________________________________________________________ > 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 ghyoungman at gmail.com From donwilh at embarqmail.com Fri Jul 13 22:54:49 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 13 Jul 2018 22:54:49 -0400 Subject: [Elecraft] Need help troubleshooting dead receive on KX1 In-Reply-To: References: Message-ID: <5a419334-ad7a-951f-c887-1fab0b45aca7@embarqmail.com> Jon, You will have to do some troubleshooting. First, check the VFO and BFO signal levels. The VFO should have a 200mVp-p signal (70mV RMS) at U6 pin 6, and the BFO should have a 200mVp-p (70 V RMS) at U5 pin 6. use an oscilloscope with a 10X probe to measure the peak to peak RF voltage or an RF probe to measure the RMS voltage. If it was working when you put it away, the most probable problem is that there is a marginal solder connection. Re-flow the soldering on the side of the RF board that is between the crystals and the headphone jack. If you have a signal generator that will develop 0 dBm, you should be able to trace through the signal path with an oscilloscope. 73, Don W3FPR On 7/13/2018 6:20 PM, Jon Ayscue wrote: > My KX1 was working fine the last time I used it a couple of years ago.

I built mine in late 2000 after a six-month wait between order and delivery. It was a deservedly popular rig. I used mine through Solar Cycles 23 and 24. It has been "hors de combat" since a DC power spike from a nearby lightning strike in 2015. I hope someday to return it to service. My KX2 is from a different realm of technology and function. I am amazed by its size and capabilities. I never go on a trip without it. There is one area where the KX2 is notably deficient, compared to the K1. That's its case color. and the problem has nothing to do with aesthetics. Black paint causes a rapid rise in temperature after only a few minutes exposure to direct sunlight...even when the KX2 is turned off! Black is a poor choice for a radio that is likely to see frequent outdoor use under temperate fair weather conditions. The case color appears chosen for style...not service. The traditional light "Elecraft" gray case color would have produced much less temperature rise in direct sunlight. White or light tan would be even better.

(I have also K3S+P3). The KX2 is a wonderful qrp rig, ultra charged with great options. But I love my old KX1, that I build enjoing building it, that worked immediately at first try, that have a wonderful rx with wonderful PBT, with wonderful QSK and a great auto tuner and a great keyer. I used it a lot 4 years ago when had a problem with my back and was confined to bed for 15 days. With internal battery discharged and 1 watt out connected with rg58 to my shack to the beam I worked great qso with W6 and W7 from Italy. It is even for today standards a little wonder, at less than half the price of a KX2. Are you sure that we dont want anymore a 400-500$ qrp rig as the KX1? The KX1mk1? 73 and thanks for your wonderful work.

Then she asked ?you said you?re a priest right??, to which I affirmed that I am indeed. ?Oh, this one will not do then,? she said, ?let me look for another.? She then gave me the callsign ?N8TTR?. I can only imagine what that callsign was that she refused to assign to me!

The following options are installed: FL1 - 13khz FM filter FL2 - 2.7 khz filter FL3 - 400 hz filter FL3 - 200 hz filter KPA3A 100 watt PA KAT3A 100 watt Tuner KBPF3A General coverage band pass KTCX03-1 High stability TCXO K144XV internal 2 meter module K3EXREF external 10mhz reference K144XV phase lock board. The K3S and options are all working. I had a problem with 2meters being off frequency after adding the K3EXREF and the K144XV reference board. I did a complete reset to factory defaults. I removed the K144XV reference board. Then set the 2 meter offset back to what was labeled on the module. The 2 meter frequency was accurate. I put the K144XV reference board back in. Now the 2 meter frequency is accurate with the board back in. My question is where is the TMP cable suppose to be connected on the KSYN3 board? I have one end connected to REF IN on the 2 meter module. I initially connected the other end to J4 on the KSYN3. I now have it connected to J1 on the KSYN3 do I have the TMP cable connected correctly? The documentation is a little confusing to me. Figure 13 page 15 on the K3EXREF manual shows J4 being used on the KSYN3A if both the KXV144 reference board and the KEXREF options are installed. There is an Errata sheet showing to use J1 on the KSYN3 board. Which one is correct to use for my set up J1 or J4? The K3EXREF is working with very accurate frequency on the HF bands with my GPS 10 MHz disciplined oscillator clock connected. The 2 meter frequency was off when connected to J4. I am not sure if it was corrupt software and doing the reset corrected the issue and am uncertain where to connect to on the KSYN3A board?

The confusion is the Errata is for the KXV144 Reference module dated Dec 5 2013 showing placement at J1 on the KSYN3A. The K3EXREF manual is dated August 23, 2016 and shows placement at J4 on the KSYN3A. Hence confusion?

The voltage rating for a fuse is "any voltage up to the rated voltage". The manual statement to use "12A fuses for 115V" does NOT mean that the fuses must be rated for 115V. 73, Don W3FPR On 7/14/2018 1:43 PM, John Clemmer wrote: > Hello. new owner of a KPA 500 and KAT 500.

"W" calls were assigned sequentially by call area, with some exclusions [e.g. W#X** calls were reserved for experimental stations ... W6XAO was Don Lee's television station in Los Angeles in the late 30's atop Mt Lee**, home to the "HOLLYWOOD" sign]. When the W's ran out, the FCC began with the K's, again by call area, and got to K6DGW in 1953. Those ran out at various times depending on call area, and they more or less standardized on WA#***.? My brother got WA6QJY [not much of a CW call] while I was at college, maybe 1960 or so, I don't remember exactly.? Novices got WV#*** which they converted to WA# upon upgrade.? WA's were followed by WB's.? They sort of skipped WC's, issued a few WD's [at least in CA], and then started in of the KA's.? That seems to have been a fairly straight progression except for having to skip some of the Kx prefixes that were already assigned to US territories ... KG4, KH2. East of the Mississippi, broadcast stations were/are generally but not always 4 characters beginning with W.? West, they were/are 3 or 4 characters beginning with K, but note KDKA in PA and WOAI in TX, KSL in SLC, KFI in Los Angeles, and KOH in Reno NV.? Coastal Marine stations followed the same pattern with 3 characters. Ships were 4 characters, those that floated mainly in the Pacific began with K, the Atlantic was home to the W's.? Ships do move around, while most of the ones I worked in 56/57 from KOK in Los Angeles were K's, there were a few W's occasionally. The Navy, which owned all the N's eventually gave them up for calls that followed the recipe for ham calls.? The Navy's/CG's coast stations still use N** calls [e.g. NMC at Pt Reyes CA, right next to KPH]. The US was also assigned AAA-ALZ, I don't remember when ham calls from that block became available, but they followed the ham call recipe.? Hope this helps a little. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County **Don Lee was wealthy ... very ... from selling automobiles, and he owned a goodly part of the ridge called Mt. Lee.? W6XAO became KTSL on Channel 2 about the time I was 8 or 9, and was joined by KTLA on Channel 5 shortly after.? CBS bought KTSL and it was KNXT for a long time, it's now KCBS-TV [KCBS-AM is on 740 KHz in San Francisco].? KTLA was still on the air from Mt Wilson last time we were in SoCal.

Message-ID: <000901d41bc3$331fed10$995fc730$@com> 230v fuses are perfect. Most people in the US will not have more than 120v on each fuse even when running 240v. I am not sure why slow blow was recommended, is that what the manual says? These fuses are easy to find, if you don't see them locally try Mouser. This IS the forum for Elecraft products, even though it doesn't always seem that way. John KK9A On 7/14/2018 1:43 PM, John Clemmer wrote: > Hello. new owner of a KPA 500 and KAT 500.

Exactly right. AND -- the breaker at the panelboard protects the entire circuit against faults that could be unsafe for personnel or might start a fire. By contrast, the fuses in the KPA protect the amplifier, NOT the circuit, from a condition where the amp is drawing too much current, and could destructively fail. SO fuses for 240V operation are specified for half the current of fuses for 120V operation (because normal current draw is half at 240V as compared to 120V). I buy my fuses from the usual suspect electronic distributors, and I've always kept a stash of standard values. 73, Jim K9YC From azstefano at mac.com Sun Jul 15 05:00:05 2018 From: azstefano at mac.com (Stephen Rector) Date: Sun, 15 Jul 2018 02:00:05 -0700 Subject: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied In-Reply-To: References: <6987944b-4a5f-af3b-bda3-b52c624e73db@embarqmail.com> <4EA64B97-12F0-46B4-B2A1-D6023D23053D@mac.com> <9a7ea828-46c7-f862-4b46-27f52349e80e@embarqmail.com> <7BA38726-70B3-4B4E-A748-BC23EF214861@mac.com> Message-ID: I'm following up here with the verified solution to my issue. To recap - When I used a KXSER cable to connect my KXPA/KX3 to my Ciro Mazzoni Magloop antenna controller, that left no port available for me to control the KX3 with RS232 using the program FLRig. The best solution I found was to use a DB9 Y-connector in conjunction with a breakout board for the DB9 branch going to the antenna controller. On that board, I patched only the RXD and ground lines: pins 2 and 5, from input to output. With this configuration, the Antenna controller has its TXD pin left unconnected. As many here noted, this is of necessity since only one TXD driver can exist on a common TXD line. So, for the controller to work, FLRig must be running and connected to the radio. Since FLRig polls the KX3 control parameters, the Antenna controller receives the VFO data it needs on its RXD line. Apparently it doesn't matter that the controller is not doing the polling, as long as something else is. If I wanted to return polling autonomy to the antenna controller, I would have to disconnect the Y-junction. But I think I will keep things in place. Just because FLRig is running on the computer, doesn't mean that I can't use the KX3 standalone as I usually have in the past. So this is an acceptable solution. I'll probably post it on Ciro Mazzoni's user site for others' benefit. Thanks all for the help and pointers! 73, Steve, NU7B > On Jul 8, 2018, at 5:07 PM, Don Wilhelm wrote: > > Sorry about the pin typo.

But based on your feedback and also that of N6TV, I see that I have multiple TX drivers on the TXD line. Even if there is no TX from the antenna controller, the low-impedance of its TXD driver will load the line. Bob also thinks the controller may be polling for info, much like the program FLRIG does. One correction to your info Don, I think TXD is pin 3 on the DB-9, and not pin 2. >> The KXSER cable DB9 shell appears to be molded - it's not obvious how to disassemble it.

Ship radio stations, OTOH, were reversed - W ships were registered in west coast ports, K ships were registered in east coast ports. This scheme for both BC and ship stations more or less went away, ships after WW-II and BC in the '70s.

That's because, with AC, the current goes to zero twice per cycle, so the arc can go out. Not so with DC.

This is incorrect! The current rating of a fuse is independent of the voltage. The fuse blows as a result of heat, which is proportional to I squared times R. The voltage rating is just a guarantee that if it does blow, it won?t stay conductive due to an arc.

I just today finished redoing the operating desk with new cabling etc. It is a real joy to have a piece of equipment work correctly and well right out of the box. Kudos to Elecraft once again. FWIW: The order date was May 15, so the delivery time was just about what was predicted on the day it was ordered. Might have come a bit sooner had the 4th of July not been in the middle of the time.. Gary at Elecraft Support advised it would be OK if the power supply were mounted vertically, so long as the clearances for air circulation were observed. There are four small rubber feet on the right hand side, so I put 1 inch blocks under those feet and set it standing on that side next to the operating desk, with more than four inches of clearance at the top, front, left side, and rear. The larger feet on the official bottom keep it stable and spaced from the side of the desk. In that configuration the main AC switch is conveniently near the top rear edge. That installation, with the side of the desk between the PS and me, cuts down the power supply fan noise considerably. It is, in fact, much quieter than the fan in the little Powerwerx SS30 that sits right on the desk powering the K3 and P3. As for the amp's RF deck, which is also desk-top in front of me, I can just barely hear the first stage fans when they come on -- while I am wearing a standard cushioned headset. I have not yet tried the higher fan speeds nor used the amp with a mic. Interesting advantage is that having the ATU in the RF deck actually reduces the rats' nest of wiring just a bit, compared to the KPA500 / KAT500 which it replaced. I always wondered why there wasn't a 13 DCV outlet on the KPA500, as there is on the K3, which could have powered the KAT500, rather than having to run a separate 13 VDC cable to the tuner. I'll bet 99% of them in the field sit one on top of the other. But no matter. That's history. In all, a happy camper.

Eric WB9JNZ was net control and I heard him fine and he heard me after a few calls. Today I could not hear Eric but did hear a few stations checking in, and a few relays. What is considered the proper procedure for a station unable to hear net control? Should I wait for net control to ask someone I can hear to give out a net call and act as a relay? Should I just keep throwing out my call and hopefully someone will hear me and act as a relay? Should I pick up my toys and go home till next Sunday in the hopes of better propagation conditions? I suppose the last option makes the most sense because is there much point to checking into a net one can?t hear. I?m running a KX3 at 10 watts into a 40m EFHW that is resonant on 20 meters from a 3rd floor apartment to a tree.

My power supply is under the table on a low stand, so is less than 3 feet from the K3s. Just FYI, but it seems I would hear something. 73, Roy K6XK Iowa I just received my new KPA1500 last Thursday. Ser. No. 316. I ordered it in Visalia on April 20. Tested it out on all bands and I am a very happy camper. I decided to place the power supply about 8 inches to the left of my K3 on a small shelf. I discovered that on 15 M, 21.020, I get a major switching power supply noise. The noise level as seen on my P3 goes up to S3. Has anyone else seen this? All the other bands are OK. I gave the amp a very good test during the IARU contest. Temp never got above 74 C. Fan comes on at 60. I received it with 01.63 firmware.

I am often in your situation when I'm in New Hampshire with my KX3. The following is what I try to do, but I would also love advice about better ways. (BTW, I wouldn't worry too much about QRMing the net. If you can QRM the net, then someone can hear you and will relay.) There seem to be two situations: (1) You can figure out when to transmit to check in. (2) You can't. If you can figure out when to call, add "need relay" to your call. If someone else can hear you, they will try to relay. (The last time I tried this technique from NH, both of use were cut off from the rest of the net.) If you can't figure it out, if you can copy someone who is checking into the net, try to call them for a relay. One of the great joys of this net is the relaying. Relaying is how amateur radio started -- it is the Amateur Radio RELAY League after all. We never know who will be relaying from week to week. This week, Phil NS7P, in Oregon was coming in S9+ with QSB into the San Francisco Bay Area, where I live. Eric, WB9JNZ, the usual net control was about S5 and faded as the net started. (Eric and I were running 1KW+.) I heard Bill, K7BRR try to checkin from Astoria, OR at about S6 and neither Eric nor Phil could hear him. Eric could no longer hear me, so I relayed the checkin to Phil who relayed it to Eric. Great practice for emergency communications. 73 Bill AE6JV On 7/15/18 at 2:03 PM, pasek001 at umn.edu (George Pasek) wrote: >Last Sunday I checked in to the Elecraft SSB net on 14.303.5 at >1800z.

I know about: 1. KPA500 and KAT500 know TX frequency and configure band, antenna, and tuning solution before transmitting 2. Adjustment of power output is based on band and KPA500 OP/STBY mode 3. Selection of band on KPA500 is passed to K3 and KAT500. I have developed an Arduino based interface that implements 1. 2 seems to be doable and useful. 3 seems doable but not very useful.

Hi, I am working with a friend to assist him in getting his K3S/P3 set up for macros... I was attempting to input a macro trigger character, using the Function keys F1-12 as the triggers. F1-F8 work fine as triggers, it appears that his K3S/P3, both running current software, does not accept F9-F12 as a trigger keys. The P3 simply ignores those characters while in MACRO MODE and inputing a macro and its trigger... My K3, (NON S), and P3, (both with current software), take those characters.

The QCX is a modern extremely sophisticated, innovative, and capaable design by Hans Summers, G0UPL. QCX Description Page: http://qrp-labs.com/qcx.html Presentation materials by Hans at Dayton FDIM; http://qrp-labs.com/images/news/dayton2018/seminar.pdf http://qrp-labs.com/images/news/dayton2018/fdim2018.pdf QCX Assembly, Alignment, Operation, and Theory Manual: http://qrp-labs.com/images/qcx/assembly3_LT.pdf This manual is outstanding in all areas. Like the kit design, it is a real tour de force. The kit requires no SMD soldering and is almost all easy TTH construction. The QCX includes all necessary built-in test signal generation and associated displays for making alignments. I don't believe there is any conflict mentioning the QCX mono-band unit on the Elecraft list because it is NOT a competitor to ANY product that has ever been in Elecraft's 20-year product line. In one year, almost 6000 QCX kits have been sold. I have recently received four of them and begun construction. There's more than enough room in my QRP world to appreciate the excellence of my three 20-year-old Small Wonders DSW mono-band units, my 18-year-old K1, my recent KX2, and my (I hope) soon-to-be completed QCX units. I love the technical innovation in every one of these.

Checking the archives it seemed it was a thermal problem so I partially disassembled the radio, cleaned out dust and reseated boards. I checked the p/s and swapped p/s and no change. The problem is not band or antenna dependent. The radio is not even warm when this happens. Any ideas before IARU contest starts tomorrow?

Perhaps for some owners this is not an issue. For me it is a significant issue. If the band change requires a change of antenna then my LP-100A may alarm on SWR before the KAT500 switches to the correct antenna and all the tuner relays clunk over to the proper selections. I much prefer to have my equipment configured before I transmit. My first approach was to drive the KAT500 band discretes with band band data derived from the KPA500 BN; response. This worked well. I then took on the challenge of deriving the exact TX frequency (to nearest 1 Hz) from FA, FB, and IF. When this information is fed to the KAT500 then the band discretes are no longer needed. Now the KAT500 not only selects the proper antenna before TX but it should also select the proper memorized tuning solution for that exact frequency. I have some more works to do and that includes optimizing the integration of my KPA500 and LP100 data logging with control of KPA500, KAT500 and SteppIR SDA-100. I wanted to know what I had missed in K3 integration advantages so I can decide how best to implement the final solution. I had no Arduino experience before I started this project. It has turned out to be fun and rewarding (and sometimes quite frustrating). 73, Andy k3wyc From challinan at gmail.com Mon Jul 16 15:56:13 2018 From: challinan at gmail.com (Chris Hallinan) Date: Mon, 16 Jul 2018 15:56:13 -0400 Subject: [Elecraft] Best powered speaker for KX3 In-Reply-To: <000001d41d3b$e43f0bc0$acbd2340$@nwlink.com> References: <000001d41d3b$e43f0bc0$acbd2340$@nwlink.com> Message-ID: I use a set of Bose Companion 2 Series III.

This started with three hours to go in FD (operating 1D at home). Checking the archives it seemed it was a thermal problem so I partially disassembled the radio, cleaned out dust and reseated boards. I checked the p/s and swapped p/s and no change. The problem is not band or antenna dependent. The radio is not even warm when this happens. > > Any ideas before IARU contest starts tomorrow? > Thanks, Mike WA5POK > > ______________________________________________________________ > 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 f1gwr at free.fr From scott.manthe at gmail.com Mon Jul 16 17:25:41 2018 From: scott.manthe at gmail.com (Scott Manthe) Date: Mon, 16 Jul 2018 17:25:41 -0400 Subject: [Elecraft] Matching the KX3's textured paint Message-ID: My KX3 had a slight accident, which resulted in a scratch on the back of the heatsink, about 1/8" x 1/3" long. I'm guessing the heatsink costs a few bucks and I understand the thermal adhesive is tough to remove, so I'm wondering if anyone knows of a textured paint that will closely match the powder coat on the KX3's heatsink?

Under past FCC rules, I had to give it up when I moved to a different call area. That actually happened twice! The first time I reacquired this call it cost me nothing! FCC just reassigned it to me as a previous holder. However, in the early 90?s, when I decided I wanted my original call again, and I was again in the 7th call district, I had to do so under the vanity program, and pay extra for it too! Even renewals were subject to a special fee! Now that has changed, thankfully.

I was attempting to input a macro trigger character, using the Function keys F1-12 as the triggers. F1-F8 work fine as triggers, it appears that his K3S/P3, both running current software, does not accept F9-F12 as trigger keys. The P3 simply ignores those characters while in MACRO MODE and inputing a macro and its trigger, if I change nothing, and press F1 it is accepted as a trigger... My K3, (NON S), and P3, (both with current software), take those characters. Is there something different with the K3S/P3 that might cause this? -- 73s and thanks, Dave NK7Z https://www.nk7z.net ______________________________________________________________ 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 dave at nk7z.net From kengkopp at gmail.com Mon Jul 16 18:25:46 2018 From: kengkopp at gmail.com (Ken G Kopp) Date: Mon, 16 Jul 2018 16:25:46 -0600 Subject: [Elecraft] OT: Call letter license plate trivia Message-ID: After an early retirement from my job Rose and drove an over-the-road semi for 5 years and a million miles.

It should work the same as the legacy serial port connection.

Answer: That is correct, I am connecting a USB keyboard to the back of the P3. I am using the term trigger as you are using the term recall key.

Answer: Yes, when I create a macro for keyboard F1, I see that character entered into the window on the P3 as the trigger character. If I backspace and enter F2 it works as well. If I were to continue it would accept the rest of the macro. If however I backspace, (after entering say an F1), and enter F8, the F8 entry is simply ignored as if I never typed a character, same for F9-F12. If I backspace and type F5 it works. THis is all using just the backspace key. Anything between F9 and F12 is not even accepted into the P3 and shown on the macro trigger display.

In an FT8 TX/RX cycle with output power 126 W my KPA500 clicks 7-8 times during 15 second transmit and 7-8 times during 15 second receive. In these TX/RX cycles my logger shows the finals temperature swings between 57 deg C and 63 deg C. During this test the KPA500 was seeing an SWR of 1.02:1 and calculated PA dissipation was 307 W. I don't think this temperature swing is likely to cause the heat sink to expand and contract significantly. The thermal mass of the heat sink is quite large and the heating and cooling periods are short. The first click happens almost as soon as the KPA500 is keyed. I think it is possible that the clicks are caused by expansion and contraction of the finals at their mounting points. Is that likely and, if so, why would it be considered normal? 73, Andy k3wyc From rmcgraw at blomand.net Tue Jul 17 08:28:52 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Tue, 17 Jul 2018 07:28:52 -0500 Subject: [Elecraft] KPA500 thermal clicks In-Reply-To: References: Message-ID: See page 14, paragraph 2 under Operation.??

This sends the ANT 1 or ANT 2 signal to the Out and then back to the In via the Y cable, while feeding same to the SDR play. Works great.? I use HDSDR with OmniRig to control my K3S from the computer and if configured as such the SDR play follows the K3S. In order to simplify a nest of cables and forgetting to push the RX ANT, I finally resorted to using the IF OUT to the SDR play. Again the HDSDR software allows configuring such that it tracks the K3S in all modes and frequencies. 73 Bob, K4TAX On 7/17/2018 8:16 AM, Steve Muenich wrote: > Hello gang, > > Is there a proper port on the K3S to connect a SDRPlay that would allow for sharing the main antenna while receiving, then be disconnected and isolated when the K3S go into transmit? > > Thanks > Steve, NA5C > K3S 10121 > > > Sent from my mobile device > ______________________________________________________________ > 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 lists at subich.com Tue Jul 17 10:16:33 2018 From: lists at subich.com (Joe Subich, W4TV) Date: Tue, 17 Jul 2018 10:16:33 -0400 Subject: [Elecraft] SDRPlay connection to K3S In-Reply-To: <9762C83C-1CD7-4F10-B9B2-69119628AEC5@gmail.com> References: <9762C83C-1CD7-4F10-B9B2-69119628AEC5@gmail.com> Message-ID: You will need a (hybrid) splitter ... connect the common port of the splitter to the RX ANT Out jack, connect one output of the splitter to RX ANT IN and connect the other output of the splitter to the SDRPlay antenna jack.

This has worked when another station near me (QRP) shared the band on FT8, which would have blocked anyone else (worst case). If you monitor (listen) to the band on digital, turn your speakers down FIRST!? ;-) Also never use noise reduction or blanking in digital, it causes distortion and may often produce ghosts in the audio (you decode them on multiple audio frequencies).

There is some confusion with the KX144XV REF LOCK manual and K3EXREF manual as to where to connect the REF IN TMP cable. I contacted Elecraft tech support. I found out there is an ERRATA dated 03/2018 for the KE3EXREF manual which did not come with my option module and is not on the Elecraft website. The KEEXREF manual shows the REF TMP cable going to J4 on the KSYN3A board. This is incorrect! The REF IN needs to go to J1 on the KSYN3A board. If you plug into J4 the 2 meter displayed frequency on the K3S will be incorrect and off frequency. Hope this my help someone else.

C135 ("103"), which sits adjacent to the 2D heat sink fastener, needs to be installed as close to the board as possible. Check that it is lower than the 2D fastener, otherwise the heat sink panel may not make good contact with Q7 and Q8. My C135 sat a tiny bit higher than the 2D block; I ended up shaving a very thin layer of the capacitor body with a razor blade so that it cleared the 2D fastener.

First, for double-hop E-skip on 6M, where openings are often brief and not very strong. Second, for weak signal conditions, and conditions on any band where the path is noise-limited. This is generally true of ALL of the WSJT modes -- legal limit is often used on VHF for moon-bounce, meteor scatter, and tropo communications.? Note that WEAK SIGNAL does NOT mean QRP. FT8 has signal to noise immunity that I would estimate as 6-10 dB better than excellent CW operators on both ends of the QSO.? When used on the HF bands, fairly low TX power is generally enough. But when used on 6M and 160M, it's common to run whatever power is needed to make the QSO. I run my KPA500 at 500W on 6M, and I'm running a borrowed KPA1500 at 1.4 kW. I don't generally use FT8 on the HF bands, although I did to work KH1 last month. My experience on 6M has been that even though I'm running high power, my signal report, which is based on signal to noise at the other end, is usually 6-10 dB worse than the report that I send.? Yesterday, for example, I failed to finish three 6M QSOs because the other station, who was reading -14 dB, couldn't copy me!? Sadly, it has become increasingly common for us to have very high noise levels, resulting from switch-mode power supplies, solar power systems, variable-speed motor controllers, leaking from CATV systems, defective components on power lines, and a host of other sources. 73, Jim K9YC I thought FT8 was a low power mode.? ?Am I wrong?? ?I am not referring to Fox Hound mode.

Having once operated EME (on CW) and meteor and tropo scatter, I can say that terrestrial path loss is not necessarily lower than the EME path.? Many years ago, W7UBI (SK) in Boise, ID and I ran twice-weekly two-meter MS schedules for over a year.? We both had EME capable stations.? The distance between up was about 850 miles, an easy MS distance but extreme for tropo.? If memory serves, our rate of completion of valid MS QSOs was in the neighborhood of 30-35%.? But what was interesting was that there were times when residual (tropo) signals were readable.? The point is that for either terrestrial mode, high power was both appropriate and necessary.? I should add that in addition to path loss, terrestrial noise is also an issue to be overcome. As to the broad (wide) signals, those are not necessarily caused by strong signals but weak receivers.

Part of this is perception rather than reality -- a failure to understand the waterfall display. Because the waterfall displays both signal strength and spectrum, a very strong signal may APPEAR to be broader than it really is. I have a half dozen or so neighbors running FT8 on 6M within about 15 miles, and all are running a power amp (mostly KPA500, but my closest neighbor, about 5 miles, runs 1.3kW.

K1JT recommends setting audio level into the computer for an indicated 30 dB on the bar graph. I think this is part of the problem caused by strong signals taking over the AGC and greatly reducing the gain. If, for example, a local who's 30 dB over S9, reduces the RF gain by 30 dB, an S9 signal would be below the level of the sound card!

It would be like turning off the power supply without first turning off the K3S, and I understand that's not recommended. Do I need a UPS for the K3S?

Date: Wed, 18 Jul 2018 01:52:11 +0000 Subject: [Elecraft] K2 - Tuning is Nonlinear Message-ID: Dear Group: I am about finished building my K2, but have encountered a frustrating problem. Maybe someone can help me. I have performed most of the alignment in Part III, but noticed the following when trying to receive signals: When I turn the tuning knob, tuning is nonlinear. On some bands, it will change frequency gradually, as it should, but then jump to another frequency. On other bands, it never tunes linear at all, but just makes large jumps in frequency as you are turning the knob. I checked this jump, and sure enough, it was 5 KHz. So the PLL is working ok. The problem is the lower bits of resolution that are processed by U5 (the DAC) on the RF Board. On two of the bands, as the knob is turned, the output of U5 (pin 7) varies from 0 to about 0.8 volts, then jumps to 4.0 volts. On one or two other bands, it just jumps the 5 KHz -- no linear parts. And on the other bands, the output of the DAC does not change at all that I can tell. I checked the output of the encoder, and it seems to be working -- at least, digital levels are sent to the microprocessor U6 on the control board. I don't know if there's something messed up in the EEPROM or the DAC or the programming of the microprocessor. Have any of you had this problem or have suggestions?

Likely the radio just won't save the last parameters.?? And yes it is never advised to turn off the power supply before turning off the radio.??? The radio saves the last used parameters when the power switch is depressed.?? This won't occur when the supply is switched off before the radio. Yes, a UPS would be nice and will prevent such events but......be sure to get one that is sine wave {they usually generate less crud}? and one that does not generate RFI and birdies.??? Usually "cheap ones" won't pass muster in this regard.? Good ones run with the output locked in phase with the power line and may actually supply power 100% of the time.?? Others switch quickly to prevent power interruptions to the load. The "quiet" method is to float a small battery, depending on how long you want to hold the system up, determines the Ah rating. If your supply is running a solid 13.8 to 13.9 then a lead acid battery of the garden/lawn mower type works just fine.? Connect the battery across the supply output.? A 20 amp or so fuse should be in the positive line between the battery and supply. ?? You should check to see when the supply is off that it does not draw current from the battery.? Most don't, yet some do.? This will discharge the battery when the supply is off. ? ? I don't advise using diodes to isolate the battery from the supply and then feed the radio due to the voltage drop across the diodes.? Plus the diodes will need to be rated at the current of the supply and/or radio current demand, and those will likely require a heat sink. 73 Bob, K4TAX On 7/17/2018 8:46 PM, Bob Novas wrote: > My house occasionally has a power failure, typically lasting less than a > minute.

If that does not fix it, try doing a Master Reset (hold the 4, 5, and 6 butons in while powering on). When INFO 201 turns to the frequency display, do a CAL PLL and check again. Check the soldering of U5 and Control Board U7 and re-test after a CAL PLL run. Lastly, Try adding a 10 to 15pF capacitor between the source of RF Board Q19 and ground. Then re-run CAL PLL. 73, Don W3FPR On 7/17/2018 9:52 PM, Cox, Norman R. wrote: > Dear Group: > > > I am about finished building my K2, but have encountered a frustrating problem.

On some bands, it will change frequency gradually, as it should, but then jump to another frequency.

The problem is the lower bits of resolution that are processed by U5 (the DAC) on the RF Board. On two of the bands, as the knob is turned, the output of U5 (pin 7) varies from 0 to about 0.8 volts, then jumps to 4.0 volts. On one or two other bands, it just jumps the 5 KHz -- no linear parts. And on the other bands, the output of the DAC does not change at all that I can tell.

We have a Generac 20kW air-cooled generator at our house, that works wonderfully! IIRC, anything larger is water-cooled. Our house has two, 200amp breaker panels. We have three A/C units, an induction cooktop, ovens, dryer, and other goodies. When I started looking for a whole-house generator, almost every electrical contractor/company told me that I needed a 37kW, water-cooled generator, which has a small car engine for a motor. Generac even told them to tell me that's what needed for the loading and wiring in my house. I had done some research, and found that Generac sold a system that works with their ATS, called Nexus (or Nexys, or similar spelling). It includes "smart switches" that go in series with each heavy load device, such that the ATS can control those switches to turn on/of various loads, depending on what's running at any given time. There was only one electrical company here in Charleston, SC, that even knew about this system, they had just taken a course on it. Needless to say, they got my business. We've been through both summer and winter storm outages, up to about 24 hours, and the whole system works great! It does "stage" the air conditioners, depending on the load. The cost is higher, but I did NOT want a water-cooled car engine running on the side of my house. I've also switched to Rennai water heaters to get rid of constantly heating water for occasional use. We do have natural gas at the house, so the generator runs on that. We were going to get a gas cooktop, but during the kitchen remodel, we found the induction cooktop is as fast or faster than gas, and keeps the cooktop very clean. We can cook stuff with a layer of butcher paper between the cooktop and the pan. Highly recommended. 73, Terry, N4TLF -----Original Message----- From: AB4IQ Sent: Wednesday, July 18, 2018 5:20 PM To: 'Joe Subich, W4TV' ; 'Elecraft' Subject: Re: [Elecraft] A/C "Soft Start" ...

We have a Generac 20kW air-cooled generator at our house, that works wonderfully!? IIRC, anything larger is water-cooled.? Our house has two, 200amp breaker panels.? We have three A/C units, an induction cooktop, ovens, dryer, and other goodies.? When I started looking for a whole-house generator, almost every electrical contractor/company told me that I needed a 37kW, water-cooled generator, which has a small car engine for a motor. Generac even told them to tell me that's what needed for the loading and wiring in my house. I had done some research, and found that Generac sold a system that works with their ATS, called Nexus (or Nexys, or similar spelling).? It includes "smart switches" that go in series with each heavy load device, such that the ATS can control those switches to turn on/of various loads, depending on what's running at any given time.? There was only one electrical company here in Charleston, SC, that even knew about this system, they had just taken a course on it.? Needless to say, they got my business. We've been through both summer and winter storm outages, up to about 24 hours, and the whole system works great!? It does "stage" the air conditioners, depending on the load.? The cost is higher, but I did NOT want a water-cooled car engine running on the side of my house. I've also switched to Rennai water heaters to get rid of constantly heating water for occasional use.? We do have natural gas at the house, so the generator runs on that.? We were going to get a gas cooktop, but during the kitchen remodel, we found the induction cooktop is as fast or faster than gas, and keeps the cooktop very clean.? We can cook stuff with a layer of butcher paper between the cooktop and the pan.? Highly recommended. 73, Terry, N4TLF -----Original Message----- From: AB4IQ Sent: Wednesday, July 18, 2018 5:20 PM To: 'Joe Subich, W4TV' ; 'Elecraft' Subject: Re: [Elecraft] A/C "Soft Start" ...

I'm quite used to the low rumble of the blower in my Alpha 77D but that ticking would be like Chinese water torture to me. Listening to an individual tick it does seem to have a ring to it. Okay the recording was perhaps not the most acoustically perfect but it certainly does sound as if the ring is from the source and not any sort of artifact. If it is from the source then I think you can probably find a way to damp it. First trick will be to identify the specific source. I had read other comments about a ticking, always imagined it to be minimal and essentially unobtrusive but if what you have recorded is anything like how it sounds sat in front of it then definitely it does sound pretty bad to me and not just in amplitude but also in its timbre, pitch, and repetition rate.

That is likely to be a more balanced level. That said I'm not sure that having the specific absolute level in one particular environment is necessarily all that useful, in this case. Having a number, defined in specific terms doesn't help me to feel one way or the other if that would impact on my operating. But if I can hear what Andy hears and it sounds anything like what he recorded then I would be looking at ways to mitigate it. Recording and amplifying the offending sound as much as necessary in order to identify the root would seem a good start. What Andy showed is that there is a ticking sound and that sound is being produced by an action on one or more materials. If they can be identified it is possible that sound can be reduced. Whetherit is a loud or quiet sound is of less significance, we all hear differently.

I'm quite used to the low rumble of the blower in my Alpha 77D but that ticking would be like Chinese water torture to me. Listening to an individual tick it does seem to have a ring to it. Okay the recording was perhaps not the most acoustically perfect but it certainly does sound as if the ring is from the source and not any sort of artifact. If it is from the source then I think you can probably find a way to damp it. First trick will be to identify the specific source. I had read other comments about a ticking, always imagined it to be minimal and essentially unobtrusive but if what you have recorded is anything like how it sounds sat in front of it then definitely it does sound pretty bad to me and not just in amplitude but also in its timbre, pitch, and repetition rate.

Yes, it may seem to come from the heatsink, because the Z bracket is fastened to the heatsink and the sound will conduct to it. The tightness of the screws may affect the amount of sound you hear. Those wanting to reduce (or at least alter) the sound intensity may want to tighten the Z bracket mounting screws a bit after several hours of operation. To tighten the screws into the heatsink (see page 22 of the KPA500 assembly manual), you may be able to open the cover of the KPA500 and use a small angled #1 Phillips screwdriver, or you may have to remove the side panel and move the PA module assembly over. The Z bracket to case mounting screws are accessible from the bottom (see assembly manual page 24), so try tightening those first. 73, Don W3FPR On 7/19/2018 9:18 AM, hawley, charles j jr wrote: > The ticking sound is clearly the resonant aluminum heat sink fins.

Good stuff Sorbothane. Sorbothane was specifically designed for shock absorption and is manufactured to outperform every other material on the market. What makes Sorbothane the best material for shock absorption? * It absorbs more than 90% of shock energy and more than 50% of vibration energy; * It performs in temperatures ranging from ?20? to 160? Fahrenheit (?29? to 72? Celsius)]; * It performs at frequencies ranging from 10 to 30,000 Hertz; * It?s damping ratio is 0.344 at 2.34 HZ; * It doesn?t support bacterial or fungal growth and is relatively unaffected by industrial solvents such as diesel fuel, kerosene, and hydraulic fluid; * It has an extremely long shelf life; and * It has a superior damping coefficient. But I wonder about that temp rating :-) On 19/07/2018 21:01, Clay Autery wrote: > Y'all are making me want to find a unit with this "issue" now just so > I can solve the mystery.... > > IF it is the aluminum fins "creaking" due to rapid thermal > expansion/contraction, one possible/probably solution is a small > Sorbothane damper attached across the fins in an appropriate spot....? > Can likely be don without measurably challenging the airflow... > > 73, > > ______________________ > Clay Autery, KY5G > (318) 518-1389 > > On 19-Jul-18 08:18, hawley, charles j jr wrote: >> The ticking sound is clearly the resonant aluminum heat sink fins. >> The mechanical shrinking or expanding is abrupt and resonates the >> fins much like a tuning fork. >> My take on it... >> >> Chuck >> Amateur Radio, KE9UW >> _____ >> From: elecraft-bounces at mailman.qth.net >> [elecraft-bounces at mailman.qth.net] on behalf of Martin Sole >> [hs0zed at gmail.com] >> Sent: Wednesday, July 18, 2018 8:37 PM >> To: elecraft at mailman.qth.net >> Subject: Re: [Elecraft] KPA500 thermal clicks >> >> I think it sounds "orrible!".

That shows clearly that the groups of clicks that happen during the heating cycle are about half the amplitude of the group of click that happen during the cooling cycles. The fan speed gives a indication of PA temperature. Although I normally record PA temperature and fan speed my logger was not running when this audio file was recorded. This morning I removed the top cover and placed two thicknesses of Scotch double sided foam mounting tape on the top cover half way between the back and the vent holes. This presses on the heat sink fins and reduces the ringing a bit. I found I could still excite the fins by plucking them with a tooth pick inserted through the air holes. Subjectively the clicks seem to have less ring to them but I need to refine my spectral analysis technique to be sure what difference it actually made. I see no reason that dampening material couldn't be place on top of all the fins except those directly under the air vent holes. More to be done but it appears that ringing of the heat sink contributes to the problem. Next step will be to find out what excites the heat sink and eliminate if possible. I know it has been stated that it's movement between Z bracket and heatsink but I need to find out for myself. For those with a concern about my priorities - both this investigation and my Arduino coding are done while watching 6 m for an opening (CT and EA worked from AZ yesterday). 73, Andy k3wyc From wa6nhc at gmail.com Thu Jul 19 13:31:25 2018 From: wa6nhc at gmail.com (Rick WA6NHC) Date: Thu, 19 Jul 2018 10:31:25 -0700 Subject: [Elecraft] Elecraft earns yet more respect Message-ID: <23175cc9-8d6d-4319-2896-38c1777de8e5@gmail.com> My KAT500 had an arc between two jumpers atop the PC board, in the middle of the KH1 DXpedition rendering it inoperable.

I don't have a KPA-500 to take apart and play with, but I just spent about an hour reviewing the images in the assembly manual, et al. Yep.... It is likely the thermal expansion and contraction of the relatively thin aluminum Z-bracket.? The Z-bracket appears to be acting as a heat sink/spreader/connector between the 4 each rectifiers and the heat sink.? There are a NUMBER of potential issues in this setup that may be causing the noise via thermal cycling: 1) In high demand conditions, the rectifiers are dumping a sufficient amount of heat into the Z-bracket to cause the aluminum to increase in temperature enough to expand just the amount required to "tink" during thermal cycling.... because... 2) The Z-bracket is relatively thin... 3) The Z-bracket is constrained from expansion top to bottom by its connection to the top and bottom of the chassis. 4) The rectifiers are secured to a "tab" that sticks out of the end of the Z-bracket that is NOT constrained from expansion in either the top/bottom or side/side directions.? It reminds me of the little metal tabs in old thermostats designed to change position with temperature in order to switch conditions on the thermostat...? also reminds me of the temperature activated auto-resetting circuit breakers.... The heat imparted to that tab by the rectifiers causes the aluminum tab to heat up and expand....? that movement is transmitted to the rest of the Z-bracket....? the Z-bracket is constrained by its connections to the top/bottom chassis plates, AND in a thin row to the heatsink...? The unequal distortion of the thin metal produces a sound under thermal cycling... There are a NUMBER of factors that may have prevented this.... Thicker material in the Z-bracket would have provided more rigidity that MAY have allowed it to resist the distortion events long enough to smooth the thermal cycling....? More importantly, there would have been more thermal mass to spread the heat dump from the rectifiers.? But we can't do anything about that part....? but perhaps some mitigation (see below). The rectifier Z-arms could have been extended to include the rectifier tab so that it wasn't a small/thin aluminum tab floating in space taking heat hits from 4 rectifiers.... The Z-bracket has a relatively small thermal connection to the heatsink...? Had the contact patch between the Z-bracket and heat-sink been larger, the heat load MAY have been able to disperse into the heatsink fast enough to reduce the thermal distortion sufficiently to eliminate the sound under high demand through the rectifiers....? maybe.? (IAW...? attached to a FIN face, rather than the base strip) Other factors I won't address at present. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Mitigation: OK... there are a number of things that might be tried to mitigate and perhaps eliminate the sound...? The bottom line (I think) is that we need to provide a better thermal pathway for the heat from the rectifiers THROUGH the Z-bracket to SOMEWHERE ELSE at a rate that will prevent the Z-bracket from distorting to the "tink point".? 1) Connections to the chassis:? The chassis has the largest relative contact patch with the Z-bracket, and has thermal mass that opens to the exterior for heat rejection.? IF we can improve the thermal conductivity of the interface between the Z-bracket arms and the chassis panels, we can INCREASE the rate and magnitude of the heat dump into the chassis panels.? The idea is already to provide continuity between the Z-bracket arms and the top/bottom panels since the paint is masked to provide a metal to metal contact.? It also attached to the rear panel at two points as well...? Here are some things that can be done to increase the thermal conductivity between the Z-bracket and the chassis panels. a) Reduce the interface gaps at top, bottom, and rear attachment points.? How smooth is the aluminum plate on the arms and rear mounting bosses?? How flat is it?? One MIGHT consider lapping those areas FLAT and SMOOTH with a true surface/fixture and progressively finer wet/dry sandpapers to a grit size of 1500 or so...? This WOULD require disassembly of the amp such that you could work on the Z-bracket by itself.? And lapping the areas flat requires that you be able to do so squarely.... likely requiring a fixture.? I would do this.? But I've been lapping processor cases and heatsinks flat for many years. b) Further improve the interfaces both thermally and electrically by making sure the corresponding areas on the chassis panels are smooth and "bright"? (no paint, tape residue, overspray, or any other contaminant....? I would wet sand these areas with a small block and progressively fine grits of sandpaper or polishing compound...? Must be careful to keep the run-out minimized along the long axis of the Z-arm contact patches, et al....? I don't see whether the paint is masked off on the rear panel at all. c) Finally, these areas should be cleaned WELL with 91%+ alcohol or other suitably low-residue solvent to get them super clean.... think, mounting a heat-sink.? THEN, on reassembly, you want to use a QUALITY thermal compound..... Arctic Silver 5 would be almost ideal. IDEALLY, you would use an electrically conductive thermal compound, BUT because in this case, we are just "gap filling" to increase the contact patch integrity, it will still be electrically connected at the SAME points it would have without the compound.? AND the compound will keep the bright aluminum form oxidizing over time. 2) Connection to the heatsink:? The thin strip/patch where the heatsink mates with the Z-bracket is IMPORTANT.? This is the only path for heat to effectively travel from the rectifiers to the heatsink where it can be rejected via airflow from the fan to the outside world.? Using the techniques above similarly. a) Lap the z-bracket face that contacts the heat-sink flat and smooth to 1500 grit minimum. b) Lap the EDGE of the heat-sink flat and smooth to 1500 grit minimum.? This removes the "black" anodizing layer and provides a full and bright aluminum to aluminum thermal interface between the heatsink and the Z-bracket which SHOULD similarly increase the efficiency of heat removal from the rectifiers/Z-bracket. NOTE:? The heatsink is part of the PRE-assembled PA module.... If you do this, you MUST be careful to NOT contaminate or damage the PA modul board, traces, components et al with lapping wastes.? DO SO AT YOUR OWN RISK. c) Properly clean both surfaces and apply the same thermal compound at this interface joint.? Use ENOUGH to provide full coverage, but not so much that you have excessive squeeze out.... clean up the excess around the edges with q-tips and paper towels... Do not use alcohol as you don't want it to wash out the thermal paste at the edges or undercut the interface connection. 3) Sound/vibration absorption/conversion:? We can't just go hog wild and stuff the box full of dampers and sound absorption material.? We don't want to reduce the interior free volume any more than absolutely necessary, and for SURE do not want to jeopardize the air flow over the heatsink and out via the fan opening. I suggest using a layer of Sorbothane 1-side PSA sheeting of the appropriate durometer and of sufficient thickness to absorb any vibration/sound from the Z-bracket that might be made during a high demand thermal cycle... The sheeting should ONLY be applied on the torroid side of the Z-bracket so as not to interrupt/block that last airflow channel between the Z-bracket and the first heatsink fin.? The more area that is covered the better.... with the trade-off being that you are consuming interior free volume.? The area on the free-floating rectifier tab is of particular importance....? the area between the rectifier board and the tab should be fully populated to the end, around the stand-offs and to within about and 1/8' (or closer if you are good) of the mounting patches of the rectifiers making SURE NOT to interfere with the rectifier packages making full contact with the bracket.? You probably can't do a continuous section on the other side of the rectifiers and past the torroid.... and probably should not try...? the torroid appears to be very close to the bracket at the tangent point of the torroid.... and perhaps a 1/4" channel left for aiflow would be better....? We don't want to cause any flow short circuits that would produce stagnant air that will heat up and work against our purposes. You could also put a 1/8" thick sheet strip on the non-mating sides of the Z-bracket ears/arms.... AND one MIGHT consider a 1/8" sheet on the interior top panel (and bottom though the area is probably not sufficient for the trouble/small additional gains). As an aside and not related really....? There is the POTENTIAL that the 40-wire flat ribbon cable could be split and bound into a "rounded" cable, but I would NOT do that without first thoroughly reviewing the schematics and examined the signal arrangements....? there may be signals that need to be separate by intervening grounds on the flat cable....? We addressed this in the old days when I built 8 foot long PATA cables with 10x CAT-5 runs by giving EACH signal it's own twisted pair partner ground.? The only benefit to this would be to improve airflow in/around where the ribbon cable sits. 4) Other thoughts:? My original suggestion to put a Sorbothane damper across the heatsink fins in some fashion to break the resonance of the sound transmitted to them.... while perhaps offering some mitigation, is likely not needed if the above is done and may well reduce efficient operation of the heatsink and airflow.? IF I did this, I think I would likely try some small diameter disks just thick enough to offer an interference fit, and insert them between fins on the front, top corners of the fins. ========================================================================== Without a unit to examine, this is my best, first SWAG at this...? I could be completely off base.? But I think this is a good start.? There are a number of additional things that could be done. I have to say though.... I am overall very, VERY impressed with the package as illustrated.? Getting what they got into THAT package and making it do what it does is a testament to fine engineering! If anyone has a KPA-500-K they want assembled, I would LOVE to have the opportunity to put one together.... my way.? 73, ______________________ Clay Autery, KY5G (318) 518-1389 From Peter at w2irt.net Thu Jul 19 17:33:44 2018 From: Peter at w2irt.net (Peter Dougherty) Date: Thu, 19 Jul 2018 17:33:44 -0400 Subject: [Elecraft] Calibrating the P3 Station Monitor? Message-ID: <000301d41fa8$2c47d960$84d78c20$@net> Hi all, I recently installed a TX MON to my P3, and the readings are seemingly far off compared to two other meters. The 1.8-54 Mhz/2kW sensor was placed where my existing Alpha 4510 meter was connected (after the amp and low-pass filter, before the tuner), so I was expecting readings that were more-or-less close. However the TX MON is reading far below both the Alpha meter it's replacing and the power indicated on my Palstar HF-Auto tuner. Here are some sample readings, all of which are using the default 500ms TXMonMenu/SensorCal setting, running into a Cantenna resistive dummy load, keying down with 27 WPM dits Frequency K3s Drive Alpha HF-Auto TX-MON 14025 CW 100 W 101-107 W 96 W 80-82 W 100 W + amp 1425 W 1229 W 1140-1150 W 7025 CW 100W 105-107 W 99 W 79 W 100W + amp 1595 W (!) 1475-1500 W 1240-1250 W 1825 CW 100W 86-90 W 94 W 73-77 W 100 + amp 1350-1425 1320-1350 W 1000-1130 On SSB, the readings discrepancies are even more noticeable. While reading the same two sentences at an even cadence and voice level, using 100W of drive to the amp, tuned to 14210 and transmitting into the dummy load, the following levels were noted. 14210 SSB 101-105 W 88-92 W 33 - 35W 1530-1560 W 1348-1386 W 675-800 W I have adjusted the sensor scale settings, and 594 seems to be fine for 20m SSB, high power, but it's still low at 100W radio-indicated output. When switched to CW, using 594ms, it's reading high; the HF-Auto's internal meter is indicating 100W even while the TX Mon is indicating 115 W, and 1650-1675 Watts with the amp on, into the dummy load, with the HF-Auto's meter indicating 1425 W. In this case, for reasonably-accurate CW on 20m, the SensorScale setting needs to be at 549ms. At that lower setting, indicated power on the TX Mon is once again far lower (1050W vs 1325 on the HF-Auto). Also, once the TX Mon gets a reading it locks it there, and doesn't seem to change a whole lot if I continue talking. Both the Alpha 4510 and the HF-Auto react as I raise or lower my voice, or speak closer or further from the mic. I can chalk up minor discrepancies of up to 5-7%, to instrument error-these aren't lab-grade meters, after all, and I'm fine with that. But the numbers I'm seeing on the TX-Mon are way out of whack with what I'm after. Has anyone else run into this situation or did I get a bad sensor, do you think? ---------------------------------------------------- Regards, Peter Dougherty, W2IRT DXCC Card Checker/CQ-WAZ Checkpoint www.facebook.com/W2IRT From don_roberts2000 at yahoo.com Thu Jul 19 18:13:03 2018 From: don_roberts2000 at yahoo.com (Don Roberts) Date: Thu, 19 Jul 2018 22:13:03 +0000 (UTC) Subject: [Elecraft] KX3 line for sale References: <668314508.7479288.1532038383549.ref@mail.yahoo.com> Message-ID: <668314508.7479288.1532038383549@mail.yahoo.com> After careful thought I am putting my KX3 line up for sale as I seldom use it since I spend most of my time using the K line.

Several years ago, I bought W6OSP's LP100A from his estate. It came with one sensor, and I bought a second, sending the first back to Larry to calibrate for me. I have one sensor on the output of both power amps, and the LP100A autoswitches to display the one that is transmitting. I'm VERY happy with it.

My KPA 500 is hooked to a TS-2000 outputting 20 watts to the KPA500 and displays the following abnormalities : 1. At frequencies between 4581 kc to 4601.6 (we are working on MARS frequencies) using USB and a waveform of M110A, the following characteristics are observed. 2. The amplifier stops transmitting briefly (less than a blink of an eye) and then resumes during a M110A transmission at multiple random times. 3. Does not appear to happen when using voice, although some stations on the MARS net have mentioned that my transmissions sometimes do drop to very low levels. 4. This drop out does not occur: a. On frequencies outside the range as listed in item #1. b. If the emission is any other type other than USB/LSB. c. When I turn off the amplifier and only transmitting using the TS2000 at 100watts. 5. Occasionally, but not every time when this event occurs I hear a relay inside the KPA500 click 6. I did the following tests in an attempt to located the problem. a. The conditions occurs whether I am attached to any one of the antennas I have here. b. It also occurs when a dummy load is attached. c. It still occurs when I switch out KAT500 antenna tuners (I have two of them).

It spent about 3 weeks unconnected from its KX3. I sent it in because the amp was faulting and shutting down with NO detection of the fault using the KX3 or KXPA100 utilities. The amp relay clicked and ? just shut down in both the CW and SSB portions of the bands running ANY power (15watts or higher). My wire antennas are resonant. The amp came back with a clean bill of health, my faults could not being replicated in the lab. The KXPA100 came back calibrated with factory test equipment (KX3) values. My 90 days of repair warranty is ticking ? The tech suggested that maybe the KX3 was overdriving the amp and suggested I do the Elecraft KXPA100 + KX3 Power Calibration. Beforehand, we eliminating cabling and power supply issues between the 2 units. I have completed the CAL 75 calibration twice (2 times quickly, as he suggested) and with 110 watts selected on the KX3, the ATU in bypass mode and dummy load connected, I get the following power outputs and SWR readings from the KX3 display. 80 and 6 meters are well underperforming ?. So far, I have had no faults, good news! Yes, the dummy load is swept as flat SWR via my RigExpert AA54. Band Watts SWR TX Gain 1.840 100 1.6 3.4 3.585 58 1.1 4.6 7.120 87 1.2 4.4 10.130 92 1.3 3.7 14.200 97 1.2 3.0 18.100 98 1.2 2.4 21.200 93 1.2 2.8 24.930 86 1.4 2.4 28.400 93 1.5 3.9 50.125 54 1.1 5.0 For TX Gain (tX.X), see the KX3 manual, Appendix B, page 54. If I put the ATU back in with the dummy load and tune each band, the above values really don?t change at all, even on 80 and 6. The tech mentioned that he was not familiar with the TX Gain values and could not share any light on their goodness or validity. Can anyone speak to their reasonableness? How do I get 80 and 6 meters to full power from the amp? Am I worrying needlessly? Sorry for the long post, help me, gurus!

There are two jumpers on the the top of the board (#12 wire?) that cross(ed) each other and arced, causing damage.? Now one of the wires is running under the board so there can be no physical contact.? My take was that this issue had happened before, now it can't, I didn't ask. I wasn't given details but some resistors have been swapped and similar changes but it wasn't explained in detail on the phone. As with other Elecraft products, some changes happen throughout the life of the product, so yours may already have the updates. Mine will return being updated to current specs and mods (plus the PC traces repaired, spatter from the jumpers arcing burned the board and some trace).? Once the arcing started, the tuner couldn't take >300 watts, so barefoot won't be an issue. The internal K3 tuner works well too, a consideration until you go QRO. 73, Rick nhc On 7/20/2018 8:18 AM, ab2tc wrote: > Hi Rick, > > I am curious as to what mods you had performed: > > "It is repaired, UPDATED with all current mods (including moving the wires > that > arced to a different configuration) and is undergoing rigorous testing." > > I am running barefoot so arcing is not likely and I do not have any > immediate plans to get an amp, but I wasn't aware there were any mods done > to it. > > AB2TC - Knut > > > Rick WA6NHC-2 wrote >> My KAT500 had an arc between two jumpers atop the PC board, in the >> middle of the KH1 DXpedition rendering it inoperable.

Below is 80, above 60. Your KPA is trying to decide which band it needs to be on and is switching back and forth with the modulation as it causes the frequency to change. The delay is simply the band change. It would require firmware changes to fix this one. 73, Jack, W6FB > On Jul 20, 2018, at 6:58 AM, W1IE wrote: > > Good morning, > > I have an interesting problem in which I hope the group here has an easy > solution. > > My KPA 500 is hooked to a TS-2000 outputting 20 watts to the KPA500 and > displays the following abnormalities : > > 1.

I have always wondered how does it?s Signal to Noise Ratio figures I?m getting from the reporting stations mean in relation to being heard using CW. In other words, how close to a SNR of 0 do I have to be to say that if I were on CW they would hear me and not need a computer? I take it that anything on the + side of zero would make it, but when watching the waterfall and listening to my receive audio (KX3) I can hear stations that I am reporting a SNR of ?10 for example. I?m running 500mw into a 40m EFHW inverted sloper and have received a few SNR 0 and +1. I have attempted to look up this information but got bogged down in the math and formulas, most of which I don?t understand. So would a reported SNR of ?10 represent a reasonable number at which the reporting station would hear me if I simply switched from WSPR to CW, all other things remain the same, or is 0 the break point? tnx de George WD0AKZ --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From dave at nk7z.net Fri Jul 20 13:05:54 2018 From: dave at nk7z.net (Dave Cole (NK7Z)) Date: Fri, 20 Jul 2018 10:05:54 -0700 Subject: [Elecraft] S Meter Lite Problem In-Reply-To: <1799716960.7270949.1532103831654@mail.yahoo.com> References: <1799716960.7270949.1532103831654.ref@mail.yahoo.com> <1799716960.7270949.1532103831654@mail.yahoo.com> Message-ID: <7a278c63-4fb6-16fc-a431-93e3ee8ce22f@nk7z.net> Hi Steve, I can confirm it works on a K3.

Last I heard from K1JT, JT65 is a few dB better than FT8, and JT9 a few dB better than JT65. I can quote from this experience on 160M with JT65 and FT8. I'm near San Francisco. For most of the winter of 2016-17, in pursuit of the last three states I needed for QRP 160 WAS, I let JT65 run all night and kept a record of all the stations I decoded. I logged stations from all continents, including a dozen EU stations, and several times a week, VK6IR (about 8,000 miles). I also logged stations from every state except VT (one I needed) and most VE provinces. This past winter, there was virtually no JT65 activity, replaced by FT8. I heard a lot east coast stations working EU, but I didn't log a single EU station. 73, Jim K9YC From k2av.guy at gmail.com Fri Jul 20 14:31:44 2018 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Fri, 20 Jul 2018 14:31:44 -0400 Subject: [Elecraft] [K3} KXV3B's extra preamp on 160m RX?

These work well on the K1 and fairly well on the K2. NOTE: the kit requires soldering of SMD components prior to installation of the header. Don Wilhelm installed mine and did a great job. I paid $55. Will sell for $39.95 plus $4 USPS tracked & insured. One kit has a spare LED and will go to the first buyer. (2) for the K2, the Rework Eliminator kit to ease the task of changing microphone types. These are long out of production and early discussion of the next batch has them higher in price. Sell for $40 plus $4 USPS. I also have a spare color decal showing the mic positions for the Rework Eliminator. If you have the old black & white or your's is peeling, these are great. $1 plus a USPS first class mail stamp. You can find ALL of the information about these accessories by using Google. For the K3 and K3s I still have: two 2.7 kHZ 5-Pole filters (make an offer) Either one or both filters are $9.95 shipping which comes with tracking & insurance, 2-3 Day USPS Priority Mail.

Several years ago, I bought W6OSP's LP100A from his estate. It came with one sensor, and I bought a second, sending the first back to Larry to calibrate for me. I have one sensor on the output of both power amps, and the LP100A autoswitches to display the one that is transmitting. I'm VERY happy with it. I'm currently using a borrowed KPA1500, and find that the amp and the LP100A are within a 1-2 percent of each other. 73, Jim K9YC ------------------------------ Message: 6 Date: Thu, 19 Jul 2018 22:17:20 -0700 From: Jim Brown To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Long wire - portable operation KX3 with tuner Message-ID: <6f579d41-273a-e1b7-ffe8-a9e406437edf at audiosystemsgroup.com> Content-Type: text/plain; charset=utf-8; format=flowed On 7/19/2018 5:16 PM, Frank Krozel wrote: > I found 20? and 13? respectively in the manual but thought there was some ?other? reference for 30? and something for the trailing wire.

My KPA 500 is hooked to a TS-2000 outputting 20 watts to the KPA500 and displays the following abnormalities : 1. At frequencies between 4581 kc to 4601.6 (we are working on MARS frequencies) using USB and a waveform of M110A, the following characteristics are observed. 2. The amplifier stops transmitting briefly (less than a blink of an eye) and then resumes during a M110A transmission at multiple random times. 3. Does not appear to happen when using voice, although some stations on the MARS net have mentioned that my transmissions sometimes do drop to very low levels. 4. This drop out does not occur: a. On frequencies outside the range as listed in item #1. b. If the emission is any other type other than USB/LSB. c. When I turn off the amplifier and only transmitting using the TS2000 at 100watts. 5. Occasionally, but not every time when this event occurs I hear a relay inside the KPA500 click 6. I did the following tests in an attempt to located the problem. a. The conditions occurs whether I am attached to any one of the antennas I have here. b. It also occurs when a dummy load is attached. c. It still occurs when I switch out KAT500 antenna tuners (I have two of them). Initially, my thoughts were that the frequency range seems to lie some where in the boundary between 3.5 and 5.0 band ------------------------------ Message: 14 Date: Fri, 20 Jul 2018 07:01:32 -0700 (MST) From: "Petr, OK1RP/M0SIS" To: elecraft at mailman.qth.net Subject: Re: [Elecraft] My finished K2 Message-ID: <1532095292923-0.post at n2.nabble.com> Content-Type: text/plain; charset=us-ascii Dear Mark, I am sending big congratulation for nice job.

It spent about 3 weeks unconnected from its KX3. I sent it in because the amp was faulting and shutting down with NO detection of the fault using the KX3 or KXPA100 utilities. The amp relay clicked and ? just shut down in both the CW and SSB portions of the bands running ANY power (15watts or higher). My wire antennas are resonant. The amp came back with a clean bill of health, my faults could not being replicated in the lab. The KXPA100 came back calibrated with factory test equipment (KX3) values. My 90 days of repair warranty is ticking ? The tech suggested that maybe the KX3 was overdriving the amp and suggested I do the Elecraft KXPA100 + KX3 Power Calibration. Beforehand, we eliminating cabling and power supply issues between the 2 units. I have completed the CAL 75 calibration twice (2 times quickly, as he suggested) and with 110 watts selected on the KX3, the ATU in bypass mode and dummy load connected, I get the following power outputs and SWR readings from the KX3 display. 80 and 6 meters are well underperforming ?. So far, I have had no faults, good news! Yes, the dummy load is swept as flat SWR via my RigExpert AA54. Band Watts SWR TX Gain 1.840 100 1.6 3.4 3.585 58 1.1 4.6 7.120 87 1.2 4.4 10.130 92 1.3 3.7 14.200 97 1.2 3.0 18.100 98 1.2 2.4 21.200 93 1.2 2.8 24.930 86 1.4 2.4 28.400 93 1.5 3.9 50.125 54 1.1 5.0 For TX Gain (tX.X), see the KX3 manual, Appendix B, page 54. If I put the ATU back in with the dummy load and tune each band, the above values really don?t change at all, even on 80 and 6. The tech mentioned that he was not familiar with the TX Gain values and could not share any light on their goodness or validity. Can anyone speak to their reasonableness? How do I get 80 and 6 meters to full power from the amp? Am I worrying needlessly? Sorry for the long post, help me, gurus!

There are two jumpers on the the top of the board (#12 wire?) that cross(ed) each other and arced, causing damage.? Now one of the wires is running under the board so there can be no physical contact.? My take was that this issue had happened before, now it can't, I didn't ask. I wasn't given details but some resistors have been swapped and similar changes but it wasn't explained in detail on the phone. As with other Elecraft products, some changes happen throughout the life of the product, so yours may already have the updates. Mine will return being updated to current specs and mods (plus the PC traces repaired, spatter from the jumpers arcing burned the board and some trace).? Once the arcing started, the tuner couldn't take >300 watts, so barefoot won't be an issue. The internal K3 tuner works well too, a consideration until you go QRO. 73, Rick nhc On 7/20/2018 8:18 AM, ab2tc wrote: > Hi Rick, > > I am curious as to what mods you had performed: > > "It is repaired, UPDATED with all current mods (including moving the wires > that > arced to a different configuration) and is undergoing rigorous testing." > > I am running barefoot so arcing is not likely and I do not have any > immediate plans to get an amp, but I wasn't aware there were any mods done > to it. > > AB2TC - Knut > > > Rick WA6NHC-2 wrote >> My KAT500 had an arc between two jumpers atop the PC board, in the >> middle of the KH1 DXpedition rendering it inoperable.

Below is 80, above 60. Your KPA is trying to decide which band it needs to be on and is switching back and forth with the modulation as it causes the frequency to change. The delay is simply the band change. It would require firmware changes to fix this one. 73, Jack, W6FB > On Jul 20, 2018, at 6:58 AM, W1IE wrote: > > Good morning, > > I have an interesting problem in which I hope the group here has an easy > solution. > > My KPA 500 is hooked to a TS-2000 outputting 20 watts to the KPA500 and > displays the following abnormalities : > > 1.

I have always struggled with port sharing software--it has been off/on flaky for me. Hamation just came out with a box that connects to the K3 and then provides 1 UBS com port plus 3 real physical com ports. All the data from each port is passed to all the other ports. So you can have a logging program, an antenna switch, and two other programs all using K3 data and able to control the K3 too!

After giving it a test drive and making a few QSOs here at home in Madison I took it up to our cabin in northern WI where it will live. I operated the Florida QSO party with it, as well as the ARRL VHF contest with no problems. I also made quite a few FT8 QSOs on 6 meters in casual operation. This past weekend I went up there for the IARU contest. I started on 40 meters and noticed no problems. Note that I do virtually all my receiving on 40 with Beverage antennas in the summer due to thunderstorm noise. After a couple of hours I went to 20. I thought that the band was awfully quiet and pretty dead. After a few hours I took a break. I was working people at a fairly good rate running about 1300 watts, but signals seemed very weak. Coming back from the break the band seemed much better. After a few minutes I noted that I had forgotten to take the amp out of standby and was running about 30 watts. So I put the amp in the operate position and all the signals disappeared. After a lot of putzing and futzing it appears that there is somewhere between 20 and 30 dB of attenuation in the receive path when the amp is in the operate position. I didn't notice it initially on 40 because I was using the Beverages. This appears to be the case on all bands. I am using resonant antennas and it is unaffected on transmit. It will put out full power on all bands with a low SWR. It doesn't matter if the tuner is in the circuit or not. So I took down the amp and for the rest of the contest I used my old amp, a Tokyo HiPower 550 without any problems. So I brought the whole thing back home and set it up here. I rebooted the firmware and then downloaded the newest firmware without any change in how it is behaving. There is no problem with the K3 or the other amp. The K3 works just fine with my KPA500 at home. So the bottom line is the KPA1500 has developed an attenuation of somewhere between 20 and 30 dB in the receive path (estimated from the S meter on the K3 assuming an S unit is somewhere between 3 and 6 dB).? I haven't done anything klutzy like leave the K3 with the receive antenna switch on with no antenna attached....I've done this before :-). I'd appreciate any advice or ideas. 73 Jim WI9WI --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From donwilh at embarqmail.com Fri Jul 20 21:02:10 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 20 Jul 2018 21:02:10 -0400 Subject: [Elecraft] KPA1500 problem In-Reply-To: References: Message-ID: <6d7e69ec-076a-aca4-e81f-0c4f21a76e46@embarqmail.com> Jim, No answers here, but email support at elecraft.com.

My experience suggests that the internal resistance of the Eneloop Pro cells is higher than the standard Eneloops, despite the Pro having the higher Ah capacity. I would expect to see such a difference manifested in the T/R test and high current draw tests. I would like to be shown to be wrong! 73 On Fri, Jul 20, 2018 at 1:53 PM Howard Hoyt wrote: > Hi all, > > I had a request to add some charts to the battery test results we > published, here is the link to the page: > > https://proaudioeng.com/portable-battery-performance/ > > Thanks for the suggestions! > > Cheers & 73, > > Howie - WA4PSC > www.proaudioeng.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 lightdazzled at gmail.com > From k9ma at sdellington.us Fri Jul 20 21:25:27 2018 From: k9ma at sdellington.us (K9MA) Date: Fri, 20 Jul 2018 20:25:27 -0500 Subject: [Elecraft] KPA1500 problem In-Reply-To: References: Message-ID: <7d01de82-e857-39d1-81c7-be0101eea9b3@sdellington.us> It sounds like the PIN diode switches are either stuck in the transmit position, or the receive path has failed. Since a mechanical relay bypasses the PIN diode switches in STBY, received signals would then get through normally. 73, Scott K9MA On 7/20/2018 19:54, Jim Fitzpatrick via Elecraft wrote: > I received my new KPA1500 in mid April.

I am now also looking for a way to provide a CAT interface to the SPE amplifier without using a separate computer program. My set up is a K3 fully upgraded with the RJ45 serial port which connects via the Elecraft custom cable to a P3. Both connectors on the P3 are DB9, ie normal serial connectors. As such, can I simply insert a further Y cable between one of the P3 serial ports and the incoming cable from the K3 and then use the extra leg (with a DB9 on the end) to connect to the SPE amplifier for CAT control ? Or is that idea too simple ? Any advice would be appreciated.

I had this set up and working FB in the past, but now I can't transmit. Since the last time I used RTTY, I have installed a KPA500 and KAT500, with their associated factory cabling. But Elecraft Support says these have no effect on the USB sound card. I'm running Windows 8.1 Pro. I am convinced that audio from an application is not reaching the USB sound card. In Control Panel I can test the speakers by playing a sound. If I do this test with the computer speakers, I hear the sound. But if I test with the USB audio codec, the K3 doesn't go into XMIT (VOX is on), and there is no indication on the ALC meter. I have rebooted the PC several times. The K3 Utility communicates with the K3s, and the Terminal can transmit in the FSK D mode. But I assume Terminal does not send audio FSK tones, so it's of no help there. I have unplugged and re-plugged the USB cable from the Elecraft equipment to the PC, but this did not solve the problem. Windows Control Panel says the audio device is working correctly.

The one item I haven?t yet upgraded since putting the KPA1500 amp in place was a two-position coax switch. I have the K3/KPA1500 on one side and a standby rig ? a K2/100 ? on the other, switching either one to the antenna feed. The Daiwa CS-201A that I have in place now is rated to 2.5 KW SSB but only 1.0 KW CW. The Daiwa 201GII has a 1.5 KW CW power rating, but it comes only with N-type connectors. I could use that with three N-to-UHF adapters, I suppose, or redo three coax terminations; but thought I?d ask first if anyone knows of a manual switch with high isolation, unused side grounded, 1.5 KW continuous power capability, and UHF-F connectors.

It will also do the same for an ACOM CAT port or an Elecraft KPA1500 3.5 mm stereo "PC DATA" connector (for non-Elecraft radios). A serial Y-Cable alone on the P3 may not work unless you take care to make no connection from the SPE amp's CAT port to Pin 3 (TXD) of the P3's "PC RS232" port. I would need to see a schematic of the CBLP3Y to make sure, but I think TXD line from the K3 must be connected to the P3 there, which means you cannot connect anything else. Has anyone ever found a CBLP3Y schematic? If so, please share. SPE amps use a DA-15 "CAT" connector. To follow the K3's frequency data, they require on that 15 pin connector: Pin 1 = RS232 RXD (DE-9 pin 2) Pin 4 = Ground (DE-9 pin 5) Pin 9 = RS232 TXD (DE-9 pin 3) (*) (*) The TXD line should only be connected if the amp. *alone* is going to "poll" the K3 for frequency data. You cannot use a logging program on the USB port to poll the radio at the same time as the amp, and you cannot connect two TXD lines to each other in parallel. To get the amp. to always track the radio, you will need to have a logging programming polling the radio continuously, or use CONFIG:AUTOINF 1, while letting the amp. "just listen" on the RXD pin. The S-BOX will be sold with a new 100% shielded Amphenol cable that has all 15 pins wired straight through. It connects the DE-15 connector on the S-BOX to the DA-15 connector on the SPE CAT. One can then break out any pin on the SPE CAT connector via internal jumpers in the S-BOX, providing easy access to any pin required (e.g. RXD RS-232, TXD RS-232, RXD-TTL, TXD-TTL, Signal Ground, Amp Relay, Remote Power ON, ALC, TX Inhibit, etc.). Connect any SPE pin to an RCA connector on the S-BOX or to the proper pins on the DE-9 serial connectors, using the jumper wires provided. Stay tuned for more info. about the new S-BOX. 73, Bob, N6TV On Fri, Jul 20, 2018 at 8:43 PM, Barry Simpson wrote: > Thank you to all those of you who replied to my earlier query regarding > band data information. > > I am now also looking for a way to provide a CAT interface to the SPE > amplifier without using a separate computer program. > > My set up is a K3 fully upgraded with the RJ45 serial port which connects > via the Elecraft custom cable to a P3. > > Both connectors on the P3 are DB9, ie normal serial connectors. > > As such, can I simply insert a further Y cable between one of the P3 serial > ports and the incoming cable from the K3 and then use the extra leg (with a > DB9 on the end) to connect to the SPE amplifier for CAT control ? > > Or is that idea too simple ? > > Any advice would be appreciated. > > Thanks and 73 > > Barry VK2BJ > ______________________________________________________________ > 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 n6tv at arrl.net > From john at kk9a.com Sat Jul 21 17:52:44 2018 From: john at kk9a.com (john at kk9a.com) Date: Sat, 21 Jul 2018 17:52:44 -0400 Subject: [Elecraft] Elecraft] Coax Switches for KPA1500 Message-ID: <000c01d4213d$2898c810$79ca5830$@com> I have had a Daiwa two position switch for decades.

I just examined a CP board assembly to verify this. However, a lot of heat (not high temperature!? they aren't the same!) is needed to unsolder the frame mounting lugs. My approach would be to melt a small amount of ChipQuik on the 5 pins as well as the two lugs using a soldering iron set too a temperature too low low to melt regular solder, ensuring the ChipQuik has blended with the solder.? Might need a bit more at those pesky lugs. Then use a hot-air gun to warm those pads simultaneously.? The VFO B encoder should then easily come off the board without damaging or loosening any other parts. I would be very hesitant to do this without using ChipQuik or its equivalent to lower to melting point temperature at those seven connection points.? Repairing a heat-damaged PCB can be quite expensive. 73, Lyle KK7P (who designed this particular board in the KX3 product) On 7/21/18 3:06 PM, Scott Manthe wrote: > The VFO B encoder in my KX3 is defective.

What is important with ear buds is the SPL rating - the higher the number, the more response you will get from them. Where impedance matters is only in low impedance speaker connections. For instance the K2 internal speaker is a 4 ohm impedance. If you connect an 8 ohm speaker to the EXT SPKR jack, you may have inadequate audio because the audio amp cannot put enough power into an 8 ohm load. Headphones OTOH tend to be higher impedance devices, and the voltage produced by the audio amplifier will be the determining factor. The K2 has limited audio (by design) because the audio amplifier is typically the culprit for receive current drain. The K2 was designed for QRP portable operation with low receive current drain. 73, Don W3FPR On 7/21/2018 10:39 PM, kevinr wrote: > I am just starting my search for a good set of ear buds to replace those > I'm using.?

I have no idea what may have made them change, unless you tried to do a Master Reset which would change the filter settings back to factory defaults, which only work well in a few K2s. It is best if you use an audio spectrum analyzer running on your computer to see where the filter passband is located in the audio spectrum. Information on how to set up Spectrogram can be found on Tom Hammond's (N0SS, now SK) website which has been preserved at http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf. If you need a copy of Spectrogram, go to my website www.w3fpr.com and scroll near the bottom of the opening page. There you will find links to Spectrogram version 5.17 and version 16. These files are local to my website. If you did a Master Reset, also refer to the K2 dial Calibration article on my website. You will have to do a CAL PLL in addition to the filter alignment (CAL FIL). Advice to all - do not do a K2 Master Reset unless you first record ALL your menu settings, including the Filter settings. The first few pages of the K2 A to B upgrade instructions has instructions for recording all you menu settings. Restore them after a Master Reset. 73, Don W3FPR On 7/22/2018 1:36 PM, Pawlak, Daniel L wrote: > I'm having trouble figuring out what's wrong with my K2 (serial 3957).

Note: If a computer or other device asserts RTS or DTR while you?re in this menu entry, the K3S will switch to TEST mode (zero output) as a precaution. The TX icon will flash as a reminder. To avoid this, make sure software has flow control and/or keying options turned OFF while you?re changing the PTT-KEY selection. TX LED on all the time: This could indicate that PTT is being held on by external equipment. (Verify that CONFIG:PTT-KEY is set to OFF-OFF if not keying via the USB or RS232 ports. Try disconnecting equipment connected to the ACC, USB, and RS232 jacks.) Also check VOX gain (unplug mic if necessary). Unless you NEED the option, turn it off....?

The PTT line is connected to Pin 7, RTS, of a serial port in my computer and runs to the ACC connector on the K3S through a Y-adapter from Elecraft .

Thanks very much for the help. 73, Jim N7US -----Original Message----- Jim, What is the firmware level of your K3/K3S? If it is 5.33 or later, there is a SAFE/UNSAFE mode for PTT-Key. An excerpt from the 5.33 Firmware Release Notes is below: * PTT/KEY USE WITH THE USB PORT IMPROVED: PC applications can activate PTT and KEY at the K3S via the USB port's RTS/DTR signals. However, initial setup of the rig's USB port by the PC may cause pulsed or continuous activation of the transmitter. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on. Applications that use PTT-KEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S. 73, Don W3FPR On 7/22/2018 5:07 PM, Jim N7US wrote: > I've lost track of the (menu?) setting that prevents the K3 or K3S > from going into TX when the attached computer is powered on.

Its a common misunderstanding that the SVGA option is simply a video adapter. In fact its also an FFT processor with four times better resolution of the basic P3. Its best to use a full HD 1920 x 1080 monitor to fully exploit the high resolution of the P3 SVGA adapter. 73 Frank W3LPL ----- Original Message ----- From: "Michael Gillen via Elecraft" To: elecraft at mailman.qth.net Sent: Monday, July 23, 2018 2:19:28 AM Subject: [Elecraft] SVGA for P3 - only looking for ten (10) replies (is that possible?)

I don?t need the keyboard/ digital features it adds, just asking if a larger (20?+) SVGA display is worth it or is the default smaller display just fine? Is there some scenario where the bigger display really makes the difference or is it that bigger is better rules?

It does for 9-pin serial ports what my Y-BOX does for the K3 15-pin ACC port, and more. The S-BOX can provide automatic band changing and frequency tracking from any modern transceiver to any Elecraft, ACOM, or SPE automatic amplifier (if supported by their CAT or CI-V monitor). It also works with the SteppIR control boxes, the SDR-IQ, and other devices designed to "listen in" on serial port traffic between a computer and a transceiver. By default, only the RS-232 RXD and GND lines of the secondary serial ports are wired in parallel to the pass-through port, so there's little potential for RS-232 communications conflicts. Details, photos, examples, schematics and an order form link may be found here: https://bit.ly/S-BOX Each S-BOX can be custom wired and labeled to match your specific hardware interface requirements. But, the S-BOX is also flexible enough to be easily rewired in the field, as needed, when your hardware changes, with no need to obtain new custom interface cables. *For K3/K3S owners*, the S-BOX can provide one or two independent FSK RTTY + PTT keying interfaces, or an easy interface to an SPE or ACOM amp. with automatic frequency tracking, without requiring any custom-made interface cables. It can also be used to remotely "power on" a K3 or K3S, with no Remote Rig box required. *For KX2 and KX3 owners*, it can be used like a "Docking Station," providing computer-generated CW keying over the DTR pin of the same serial cable that is being used to control the radio, using only economical TRS-to-RCA stereo cables and a standard serial cable or a USB-to-Serial adapter, no WinKey required. The S-BOX also makes it easy to connect the KX2 or KX3 to an automatic linear amplifier without the need for any custom-made or home-brew cables. *For KPA500 and KPA1500 owners*, the S-BOX makes it easy to connect the XCVR or PC DATA connectors to the KX2 or KX3, or to non-Elecraft transceivers (Kenwood, Icom, FlexRadio), for automatic band changes and tuning, without having to rely on the "RF sense" feature. No hand-built "Cross-Over-Serial" cables required. The S-BOX can also be used to remotely and independently "power on" or "power off" a KPA500 or KPA1500, with no Remote Rig box required. The S-BOX includes four internal NPN open-collector keying circuits (CW, PTT, FSK), optionally keyed via any of the serial port TXD, DTR, or RTS pins using logging software, so you can key CW over the rig's serial cable, even if the radio doesn't support that feature (e.g. KX2, KX3,TS-590S, IC-7700, IC-7800). One can also key CW or FSK RTTY via a separate serial port, or key two different radios independently, using one or two serial ports and a single S-BOX. FYI, my other product, the Y-BOX, is still in production, and is especially useful to owners of the K3/K3S, KAT500/KPA500, or KPA1500 and SteppIR (see https://bit.ly/Y-BOX). The S-BOX can optionally be "daisy chained" to the Y-BOX, via a standard M/M DE-15 cable, or connected using RCA patch cables. Connecting the two is mostly useful if you need FSK/PTT serial keying or the K3 Remote Power ON feature. Thanks to Elecraft and all the Elecraft owners for your continued support of these projects and these reflectors. 73, Bob, N6TV From mspetrovic at gmail.com Mon Jul 23 09:56:40 2018 From: mspetrovic at gmail.com (Mark Petrovic) Date: Mon, 23 Jul 2018 06:56:40 -0700 Subject: [Elecraft] About a two-phase install of the KSB2 option on a modern K2 Message-ID: I have a couple days of available bench time this week before I go on vacation.

If you remove W2 and W3, you can restore receive by placing a bent wire jumper from pin 1 and pin 3 of both J9 and J10. Similarly, transmit can be made operational by installing a .001 capacitor between pins 7 and 12 of J11 (or you can leave C167 installed until the last minute before the KSB2 is installed). 73, Don W3FPR On 7/23/2018 9:56 AM, Mark Petrovic wrote: > I have a couple days of available bench time this week before I go on > vacation.

However the benefits of the SVGA option include: Better ?view? into the spectrum when operating Split/chasing DX With the better resolution comes the ability to ?see? smaller signals and pull them out of the noise With the larger display there is more physical area to see things including longer timeline of the waterfall (two minutes?) Easier to see if eyesight is diminished/diminishing for us older folks Quicker to glance over and see the important stuff as it is larger The built-in FFT processor provides much better resolution (4x?) and 1080p (1920x1080) Larger decode window for PSK/CW modes So the consensus is that the option is worth the cost if you have room for the monitor (which really can be anywhere from 20? up) however the P3 stands on its own quite nicely. My P3 arrives today sans SVGA option so I?m going to use it for a while ?barefoot? (Hi Hi) before I decide to add in the SVGA. 73 Michael KK6RWK > On Jul 23, 2018, at 7:27 AM, Bill Frantz wrote: > > And if you are using PSK or CW decoding, the SVGA gives you a much larger decode window and so more time to read what is being decoded. > > 73 Bill AE6JV > > On 7/22/18 at 8:17 PM, jim at audiosystemsgroup.com (Jim Brown) wrote: > >> On 7/22/2018 7:27 PM, Randy Farmer wrote: >>> If you're doing split frequency DX chasing or Search & Pounce in contests, the big screen is a VERY valuable resource.

I kept WB4SBE for 30+ years, even after moving to Ann Arbor, MI in 1982. I finally got off my keyster and passed my 20 WPM Extra in the early 2000's, just before the FCC lowered the code requirement to 5 WPM for all license classes, and eventually doing away with it altogether. Armed with my newly-minted Extra, I figured it was high time to look into a vanity call. For one thing, I had been plagued in certain contests with folks guessing my section as "Virginia?" because of the 4 in the call sign. Don't know why "Michigan" sounds so much like "Virginia", but I figured that changing to an 8 would fix that. I toyed with going with something like my initials (DN or DEN), but I shied away from DN since that is too easily mistaken for "/", and I think DEN was taken in all the short suffixes (W8, K8, N8) at the time. So, I found that N8SBE was available, and I figured the 'locals' would know who I was, based on just changing the prefix. Anyway, "Side Band Engineer" has a nice ring to it (as does "Subacute Bacterial Endocarditis", a throat infection, as related to me by a doctor on 20m phone one day), although I've found that on phone contests, "Sierra" is frequently mistaken for "Kilo", and has resulted in busted QSO's (and even more annoying, N8KBE is now found in the super partial check database, even though that station has not been active in the contests). I've tried using "Sugar Bravo Echo" and had Spanish-speaking stations correct me back to "Sierra Bravo Echo", so I guess you just can't win. On CW, N8SBE has a really nice swing to it, with mostly alternating dahs and dits in groups, helping to separate the characters. What's really funny though, is that the "BE" on the end is the same as the old 'knock/knock" that a a lot of old timers ended QSO's with, and I've actually had folks respond to my callsign with "dit dit". I don't know if they are just letting me know that the frequency is busy, or if they are just playing along with the joke. All I know is that I've had a lot of fun on ham radio over the years (coming up on 50 in 2020), and moving up to Elecraft (first a K3/P3 in 2009, and now K3s/P3 and KX2) has really enhanced my enjoyment of the hobby. Seems I'm discovering something new every day. I made FT8 contacts for the first time recently, using DXpedition mode with the KH1 folks, and it was really nice knowing that they had just as nice of radios on their end as mine. Thanks, Elecraft. 73, -- Dave, N8SBE From n8sbe at arrl.net Mon Jul 23 15:56:52 2018 From: n8sbe at arrl.net (Dave New, N8SBE) Date: Mon, 23 Jul 2018 12:56:52 -0700 Subject: [Elecraft] =?utf-8?q?SVGA_for_P3_-_only_looking_for_ten_=2810=29_?= =?utf-8?q?replies_=28is_that_possible=3F=29?= Message-ID: <20180723125652.1fa1e31b6b6b329ecc65be958babcc1f.32b04273d9.wbe@email09.godaddy.com> I think it unlikely that it could support spots easily, but I agree that it would be very valuable to be able to use a mouse to click on signals to QSY. I know the P3 has a turn 'n push knob, but mouse interaction would be a lot faster. For those that generally hold a frequency during normal CW/SSB contesting, you may not care for or need a large waterfall display. For those of us little pistols that resort to 'search 'n pounce', it's a miracle worker. 73, -- Dave, N8SBE > I really wish it were possible to implement the features of NaP3 on to > the display.

Since I have the K3S and now the KAT-500,? I've "trained" the KAT-500 for the antennas and frequencies on each band.? With the VFO tracking, I dial the frequency and everything follows. Specifically the KPA-500 I find to be very quiet, it delivers 500 watts + on every band, 160 - 6M.? Drive power is about 25 watts on every band.? The fan is quiet and is of no concern even at the highest speed.?? It does step down quickly as the amp cools. Normally the fan is off until the temperature rises.?? Using it on FT-8 at 500 watts out, it will increment to #2 on occasion.??? The input always appears as a 1:1 SWR to the transceiver.??? The high SWR circuit does protect the amp and is fast.? With my station configuration I feel as though I have a 500 watt transceiver, automatically selecting antennas and tuning as needed.?? I touch nothing but the VFO knob or enter the frequency for the next band.?? Everything switches silently and automatically. I come from a line of tube amps in the 1000 to 1200 watt class. Fans run all the time.? Power output varies with band as well as drive requirements.? Most seem to be optimized for 20M.?? My last tube amp was a AL-80B and it was one of the smoothest tuning amps I've used.? Power out always 1000 + watts.?? But it required tuning with each frequency and band change. The difference in power is 3 dB or only 1/2 S unit.??? All works for me.? I vote for the KPA-500. 73 Bob, K4TAX On 7/23/2018 8:22 PM, Rick Reynolds wrote: > I'm looking at upgrading my amp.

By the way as an Icom owner of both the 7300 now parked unplugged and for sale and the 7610 the cw qsk is better in the 7610 but? the K3 is my choice for split frequency DX QSK exchanges over both of the Icom radios the 7610 is a big improvement how ever I find it clumsy to work Split listening up stuff .... the Internal Keyer in the K3 is much better there is a better range of adjustments available in the Elecraft internal keyer ....would I like to see it like the Supper CMOS 3 keyer choices heck yes ....Icom gives you little choice my fist after a lot of practicing and paying attention is better with the Icom but not as good as the Elecraft Mode A Mode B is most important choice but even more choices would be nice like the length of (each element) not just the spacing between each element. One important discovery the 7610 muted VFO A from a S9 signal just up the band on vfo B while chasing the Baker Is DX-Pedition it took me a while to (find) out this is what was going on wanting to master the listening up pile up with the 7610 and only one VFO knob? takes getting used to the cw monitor side tone is 5 taps deep in the menu to change I can not hear it well enough even set at 100% you have to turn down the RF gain making the guy on the island weaker copy then turn up the AF gain making the side tone for my fist louder so I can hear what I'm doing on the paddle, (self defeating) and *stupid* The cw side tone is tied to the *flipping* AF gain not separate like in the K3..... *stupid*. If you can't hear the island on one VFO because a big signal is a couple cycles up push his button never listening to *hear the guy on the island* who he is working or know if he is calling Mr button pusher that kind of qrm is not necessary nor productive to the run rate. Mr button pusher was not working QSK was he waiting for a computer to tell him the island is calling????? You can't fix *STUPID*..............front end muting from a big signal near by is a problem. Now change to head phones you ears get blown up by the side tone level needing 5 taps deep in the menu then adjusting it even one more time *stupid* at the very least this adjustment needs to be in the MULTI button empty spot menu ...........like it is for SSB don't hold your breath waiting to Icom to fix this over site. Both radios drive the KPA500 well the hook up is straight forward easy to do QSK? relays perfect the best. Oh yea Icom needs a menu setting SPK+Phones, a rear plug for 3.5 Mic input and 3.5 Elec-Key input. ?Back to Baker Is DX I finally gave up switched to the K3 bam in the log ...... You get what you pay for there is a lot to like with the 7610 a lot, many features you don't get with the base set up in many other radios the price is really good but if you want to race? Pro Stock it is not cheep performance counts and cost.... Not sorry.. never have been on my choice I have put a helper fan on top to push air as soon as the amp comes on cooling it from before key down lower start temp.

To be fair a TV is always going two computers big monitor all making the room hotter. I get a couple more minutes till the temp runs to 65c kicks speed 3 on which is my time out timer to turn it over,? the equipment is also stacked to save space I found that at full song speed 3 kicks in if I'm in the middle of some sentence and keep going the fan will run at speed 3 then go back to speed 2 .....be nice to set the on set of speed 3 a bit higher in the tempeture range. This amp is well built really does the job I'm happy happy happy, and yes my Z bracket has the correct length hold down screws it will click when cooling down ( not always ) not real objectionable for me the fan noise more annoying. The screws were re-tightened after a heat cycle one at a time like you do with race engines. I also took the advice to run the amp to its limit not at 400w out it does seem the final is most efficient and running a tad cooler and longer before speed 3 which is annoying and to be avoided in my opinion. The helper fan starts things from a cooler lower temperature as well giving a bit longer run time to speed speed 3 another thing that can be done which I did before the helper fan is run speed 1 at turn on keeping the idle temp lower. The Quadra has been in stand by ever since the KPA500 made it debut plugged in and doing its timed maintenance mode, running the relays and noisy fans. I would switch between them, now its not even plugged in I do not see the need for what I'm doing....say that to say this I just might get the new 1500 if I can sell the Quadra ( new 1998) never an inrush current problem first run second version was the best, the only problem replaced the 4 meter lights a few years ago. Elecraft ATU is so good compared to the Quadra with? RF sniffing power needed is a speck in the ocean compared to the 50 watts into a perfect load Mr Quadra want's to see. Regards Art ka9zap /*After much investigation and consideration I elected to purchase the KPA-500/F.?? Since I have the K3S and now the KAT-500,? I've "trained" the KAT-500 for the antennas and frequencies on each band.? With the VFO tracking, I dial the frequency and everything follows. Specifically the KPA-500 I find to be very quiet, it delivers 500 watts + on every band, 160 - 6M.? Drive power is about 25 watts on every band.? The fan is quiet and is of no concern even at the highest speed.?? It does step down quickly as the amp cools. Normally the fan is off until the temperature rises.?? Using it on FT-8 at 500 watts out, it will increment to #2 on occasion.??? The input always appears as a 1:1 SWR to the transceiver.??? The high SWR circuit does protect the amp and is fast.? With my station configuration I feel as though I have a 500 watt transceiver, automatically selecting antennas and tuning as needed.?? I touch nothing but the VFO knob or enter the frequency for the next band. Everything switches silently and automatically. I come from a line of tube amps in the 1000 to 1200 watt class. Fans run all the time.? Power output varies with band as well as drive requirements.? Most seem to be optimized for 20M.?? My last tube amp was a AL-80B and it was one of the smoothest tuning amps I've used. Power out always 1000 + watts.?? But it required tuning with each frequency and band change. The difference in power is 3 dB or only 1/2 S unit.??? All works for me.? I vote for the KPA-500.

Perhaps it is a question of semantics, but Flex did start shipping the PGXL starting in May (the week after Hamvention). I received mine the week after Memorial Day. However, on 5 JUL 18 FlexRadio Systems released an e-mail that states in part, "Last month, as more users began exercising the 6-meter (6M) band in the exciting new FT8 mode, units began showing stress in a way not previously experienced. As a result, an issue in the post-amplifier 6M filter was identified. Our engineering team has already identified root cause and incorporated changes into the design to resolve the stress issues with the amp. Unfortunately, this has further delayed our delivery plan, and at this time we expect to resume shipments in approximately 8 - 10 weeks.? Arrangements are also being made for PGXL owners to ship their units back for repair at Flex?s expense and the two-year warranty will be reset to when the unit is returned to the owner following update. In the meantime, FRS suggests that owners not run their PGXL above 500 Watts on Six Meters. I have not yet been contacted by Flex to ship my unit back; I presume they?re spacing returns in order to minimize turn around time. As I don?t have a six meter antenna, this limitation doesn?t impact my current operation. I also have an Elecraft station at the same QTH (K3-P3-KPA500-KAT500, Remote Rig for use with the K3/I0 located elsewhere) and obviously don?t operate six meters with it as well. So yes, a PGXL ordered today will not be immediately delivered and I have no idea at this point as to their order backlog, but FRS did initiate deliveries in May and from I?ve heard from those that have them are really excited about the amp. What is more concerning to me is that the automatic tuner to accompany the PGXL is still under development. Given the lack of a tuner that can handle the PGXL, I?m essentially limited to use of my tri-bander whereas the KAT500 allows me to tune up the EFHW I have for whatever band segment I want for use with the K3/KPA500. Bottom line is that for remote operation (my primary means of operating HF), there are significant advantages in using the FRS approach to product design, but there are other advantages with using the Elecraft product line which is why I?m keeping my Elecraft setup. In my mind, the ?perfect remote setup? would be a blending of the two systems? ;-) FWIW, Barry, WD4ASW Keller, TX (Currently in Columbia, SC) > > -larry (K8UT) > > ------ Original Message ------ > From: "john at kk9a.com" > To: elecraft at mailman.qth.net > Sent: 2018-07-24 08:12:53 > Subject: [Elecraft] Amp comparisons > >> K7ERQ left EHAM reviews on both, it would be nice if he wrote a >> comparison.

I am working on this macro string for use in DXLab to set the K3 and P3 for 17M PSK operations. So, it's designed to: 1. Turn off the VOX 2. Set MODE to DATA, data mode to DATA A 3. Set LINE IN 4. Mic (Line) Gain to 3 5. Monitor Level to 3 6. Then set the P3's center frequency to 18101.50 kHz with a SPAN of 4 VX0;MD6;DT0;XF2;MN255;MN053;UP;UP;MG003;ML003;MN255;#CTF+00018101500;#SPN000 040;MN255; The macro as written performs Steps 1 - 5 on its first execution but will only perform Step 6 - the P3 commands - on the second execution. After the first execution, the center frequency on the P3 shows what appears to be a random frequency, and the correct frequency is only shown on the second execution of this macro. I think there is some band stack effect or something going on but the command set for the P3 is limited. It's no burden to click the button twice, but I'd like to understand why all these commands cannot be executed with one execution of the macro string.

The 1.3K has a 1db compression point of about 1300 watts although it will put out 1500 if it's pushed. If anyone is interested in a lightly used 1.3K let me know.

The K3(S) has an IF frequency of 8.215MHz. So when you listen to, say, 21.4, the synth is generating 21.4 + 8.215 = 29.62MHz. Multiply this by 3 and add the 8.25.MHz and you get 97.06MHz! The K3's mixer has a *very* strong response to the 3rd harmonic of the LO since it is essentially a square wave. The responsibility for removing this spur is entirely with the HF filter which evidently does not have enough suppression to totally reject this extremely strong signal. Do you have the tuner in the K3? Turning it on would probably help since it is low pass in nature. An external auto tuner should also help. Your ICOM radio probably is an up conversion radio so would not have this particular problem (responding to odd harmonics of the LO).

The advantage of the SPE is that it is instant on, operates on six meters, has multiple antenna inputs and does not generate as much heat in the shack. Its disadvantages are audible noise which for me is horrific and also I am getting RF noise on six and ten meters which does not show up on the lower bands. Literally I see the S meter go up an S unit in noise when I push the operate button. The Acom 2000A is a valve amp and is quiet operating without electrical noise. It is more tolerant of higher SWR antennas such as the SteppIR trombone on 30M - the SPE can generate hash on thirty meters annoying other hams if I am not careful. Generally, I prefer to use the Acom 2000A but for HF DX I sometimes use the SPE Expert 2k just to avoid a 2.5 minute warm up. I am beginning to think that the new Elecraft KPA 1500 may be added to the shack to replace the SPE amp. I suspect the Elecraft amp is also quite noisy compared to the Acom 2000A which uses valves. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Victor Rosenthal Sent: 24 July 2018 19:11 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Which Amp ?

When I received my 1.5K it was 21dB gain. I polled a few of the other new owners and they all reported around 21dB gain. Some 1.3K owners also reported the same high gain. To be honest most of the users that contacted me were happy with the higher gain as they were using them with QRP rigs like the KX3. I wanted a 15dB amp so that I could easily switch between the amp and my ACOM 2000 with a true 14.5dB gain The SPE manuals are specific in saying use ALC to control the power. At that time I was following the SPE1.5K reflector, and many users were doing what they were told, that is turn the rig up to 200W and let it fly. So many would not notice the drive power. Would you do that? Certainly not me? Fortunately SPE USA took my 1.5K back for a full refund, and I ordered the KPA1500. - Paul KW7Y At 12:10 PM 7/24/2018, Victor Rosenthal wrote: >The manual for the SPE 1.3K found on the Expert Linears website >indicates that gain is 14.5 dB, and the documentation states that it is >FCC approved. > >It is possible that there is an internal attenuator that may be disabled >for amplifiers sold in countries that do not have a gain limit. > >The comment about the US importer is unfair. > >73, >Victor, 4X6GP >Rehovot, Israel >Formerly K2VCO >CWops no. 5 >http://www.qsl.net/k2vco/ > >On 24/07/2018 18:14, Paul Baldock wrote: >>One point to note is that your SPE1.3K and the SPE1.5K amplifier I >>owned for a very brief period are illegal 1300W/10W = 130 = 21dB >>gain. >>FCC 97.317 reads: (2) Not be capable of amplifying the input RF power >>(driving signal) by more than 15 dB gain.

You can do that without any 1/8 inch to 1/4 inch adapter. The resistance of each earpiece should be easy to check with your ohmmeter and be revealing if there is a cord problem. The left channel (tip) should compare with the right (ring) unless something is open or shorted. 73, Don W3FPR On 7/24/2018 4:23 PM, Clay Autery wrote: > Anyone ever had a ProSet two fail to deliver two channel output when > everything is set up correctly (aka bad cable or failed R channel solder > joint at one end or the other)? > > My Elmer has a set bought in April of this year and has never been able > to get right channel.?

Normally the fan is off until the temperature rises. Using it on FT-8 at 500 watts out, it will increment to #2 on occasion. The input always appears as a 1:1 SWR to the transceiver. The high SWR circuit does protect the amp and is fast. With my station configuration I feel as though I have a 500 watt transceiver, automatically selecting antennas and tuning as needed.

I quote: "importing and/or selling an illegal amp is illegal. That tells you a lot about the US rep." The flaw in your logic is simply that they are not importing illegal amps. This also may be news to you but US hams ARE allowed to use an amp with more than 15db gain. FWIW as the amps are imported they are NOT capable of greater than 15db gain and are completely legal. The amps CAN BE modified after import to provide greater gain. The US rep and his wife are nice people an do not deserve that comment. Should you ever go to the Dayton Hamvention stop by and talk with them as I do each year. I have no affiliation with them. I sincerely hope your accusation presented as fact is just due to ignorance of the facts and I hope to help here. Also note that it is a not so well kept secret that the Elecraft KPA-500 can also be modified to provide much greater than 15db gain as well. That does not make Elecraft criminals either and I would also dispute any claim to the contrary in their defense also. I greatly enjoy my 10W K3s and KX3 when I use them with either my KPA-500/KAT-500 or my SPE-1.3Kfa. I also use them in a legal and responsible fashion to keep a clean signal on the air. Others should feel free to do the same whether they operate under antiquated FCC regs or happen to live in any other country. For non US hams I can only imagine how you must view this tempest in a teapot we live with. 73, Joe, W8JH ----- 73, Joe, W8JH K3 1713, KPA 132, KX3 7498 -- Sent from: http://elecraft.365791.n2.nabble.com/ From ua9cdc at gmail.com Tue Jul 24 18:22:02 2018 From: ua9cdc at gmail.com (Igor Sokolov) Date: Wed, 25 Jul 2018 03:22:02 +0500 Subject: [Elecraft] Which Amp ?

If it is that bad, then why FCC had approved it? If it is that bad, how do I manage? to use it with two radio on the same band and spacing of 3-5 kHz using two antennas separated 200 meters? Last year we had 2 combo of K3 and SPE 1.3 running in Field day contest. Both amps where fed from the same generator and we could easily run SSB and CW on the same band when antennas were separated less then 200 meters. May be other amps are even cleaner but what SPE does is more then enough to me. After all, IMD of 1.3K-FA measured by ARRL (Third-order intermodulation distortion (IMD): 3rd/5th/7th/9th (14 MHz, 1300 W PEP):??? ?31/?39/?57/?55 dB.)? is quite on par with IMD of K3 itself (Third-order intermodulation distortion (IMD) 3rd/5th/7th/9th order (worst case band):??? HF, ?29/?43/?46/?51 dB PEP; ) and pretty close to KPA 500 (Third order intermodulation distortion (IMD): 3rd/5th/7th/9th: 34/53/46/54 dB below???

I first experienced this in 1953 (before I was licensed) with stations near me on 930 kHz and 1470 kHz mixed on 3870 (I think). This is nothing more than passive intermod, and can occur virtually anywhere, including in one of the transmitters! I also experienced it intermittently when I lived on the northside of Chicago three miles N of Wrigley Field, and the mixes were of 50kW stations with TX locations 20 miles W of me.

FWIW, I'm running FT8 at 1400W on 6M with a borrowed KPA1500. Depending on which wattmeter you believe, it takes 38-42W of drive. Yes, you set KPA1500 output power by setting drive level from the K3. 73, Jim K9YC From paul at paulbaldock.com Tue Jul 24 18:59:48 2018 From: paul at paulbaldock.com (Paul Baldock) Date: Tue, 24 Jul 2018 15:59:48 -0700 Subject: [Elecraft] Which Amp ?

Well, FWIW I purchased a brand new SPE 1.5K amp from Bob the importer and distributor. The gain was measured to be around 21dB. As it did not meet the published spec which I requested, Bob agreed to take it back for a full refund including shipping. I didn't say he wasn't a nice guy.

My understanding -- Any *manufactured* amplifier that is sold in the US (by a manufacturer or distributor) must have 15dB or less gain. Also there must not be a simple way to modify it to a greater gain. That is the way I read the FCC rules. BUT any amateur may build an amplifier with greater gain for himself, and can sell the same at a hamfest or other flea markets without restriction. But he cannot be a manufacturer or distribute multiple amplifiers of that type. So it is perfectly legal to sell an individual amplifier with greater than 15dB gain - it is NOT legal to do so on a commercial basis. So, if the stock SPE amplifiers being sold in the US have greater than 15dB of gain as they come from the manufacturer or distributor, they are not legal for sale in the US. Other countries do not have similar restrictions. I will not post further on this topic. 73, Don W3FPR On 7/24/2018 6:19 PM, W8JH wrote: > Paul, > > Your statement is completely incorrect and unfair.

Drive power is about 25 watts on every band. The fan is quiet and is of no concern even at the highest speed. It does step down quickly as the amp cools. Normally the fan is off until the temperature rises. Using it on FT-8 at 500 watts out, it will increment to #2 on occasion. The input always appears as a 1:1 SWR to the transceiver. The high SWR circuit does protect the amp and is fast. With my station configuration I feel as though I have a 500 watt transceiver, automatically selecting antennas and tuning as needed.

The first question I will ask do you have resonant antenna for 15 meters. If so often this in itself will attenuate an FM signal by at least several S units. If you have a transmitting type low pass filter with a cut off frequency above 10 meters, or above 6 meters if you use this band, you could try putting it between your rig and your antenna. However these filters would not be appropriate if the antenna has any significant SWR?say over 2:1. This might give you enough attenuation of the FM signal and I suspect the filter would introduce less than a dB of loss in signal. If this does the trick, but introduces too much loss on TX, you could move the filter inside the rig, but route it so it would only be in the RX path. Another idea is to try a coax trap in the rx path only, would only involve a T connector and possibly a few adaptors?.research this in an antenna handbook, etc. You could try this on the rx jack on the rear panel first then move it inside. Another idea instead of a coax stub, try an LC trap?just a series C and small L (a few turn coil?very small) shunted across the RX path. Either of these ideas may or may not give you approximately the 30 dB attenuation you will need. Once again, if you have something like a random wire, endfed half wave, etc type of antenna it may let in lots of the FM signal, but a resonant Yagi, or even a dipole often, but not always, will be a rather poor antenna for the FM broadcast band. Just another thought. Try turning off your preamp for 15 meters?.probably not needed for 15 meters?however since the QRM is only S6, I doubt that this is the problem.

The K3 1st IF is at 8.2 MHz [or so].? The VFO injection is above the recv'd freq on 15, the 3rd harmonic of that plus the 1st IF comes out to 90 MHz.? When I was in FM/TV b'cast while in college, the FM deviation was +/- 75 KHz for an occupied channel of 150 KHz [may have changed, that was pre-stereo/pre-subcarrier days].? The JA rig's are probably up-conversion and the math doesn't work out.?? If the station is close it's very strong.? My HF mobile did very strange things when I parked at the TV transmitter at work.? This may have already been suggested, as soon as I saw your email I pulled out the calculator and voila! I think you said it got much weaker when you powered the K3 differently.? If so, the 90 MHz signal may be sneaking in on the power lead and a 90 MHz trap at the PP connector might suppress it enough.? You may not need to supress it very much before it disappears. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 7/24/2018 4:22 PM, Frederick Dwight wrote: > Mike, I have not had this particular problem with my Elecraft rigs, but have solved similar problems on other equipment. The first question I will ask do you have resonant antenna for 15 meters. If so often this in itself will attenuate an FM signal by at least several S units. If you have a transmitting type low pass filter with a cut off frequency above 10 meters, or above 6 meters if you use this band, you could try putting it between your rig and your antenna. However these filters would not be appropriate if the antenna has any significant SWR?say over 2:1. This might give you enough attenuation of the FM signal and I suspect the filter would introduce less than a dB of loss in signal. If this does the trick, but introduces too much loss on TX, you could move the filter inside the rig, but route it so it would only be in the RX path. Another idea is to try a coax trap in the rx path only, would only involve a T connector and possibly a few adaptors?.research this in an antenna handbook, etc. You could try this on the rx jack on the rear panel first then move it inside. Another idea instead of a coax stub, try an LC trap?just a series C and small L (a few turn coil?very small) shunted across the RX path. Either of these ideas may or may not give you approximately the 30 dB attenuation you will need. > Once again, if you have something like a random wire, endfed half wave, etc type of antenna it may let in lots of the FM signal, but a resonant Yagi, or even a dipole often, but not always, will be a rather poor antenna for the FM broadcast band. Just another thought. Try turning off your preamp for 15 meters?.probably not needed for 15 meters?however since the QRM is only S6, I doubt that this is the problem. > Rick KL7CW > From vr2xmc at yahoo.com.hk Tue Jul 24 19:53:04 2018 From: vr2xmc at yahoo.com.hk (vr2xmc) Date: Wed, 25 Jul 2018 07:53:04 +0800 Subject: [Elecraft] Which Amp ?

Joe, I do not know where the info about SPE being dirty comes from. If it is that bad, then why FCC had approved it? If it is that bad, how do I manage? to use it with two radio on the same band and spacing of 3-5 kHz using two antennas separated 200 meters? Last year we had 2 combo of K3 and SPE 1.3 running in Field day contest. Both amps where fed from the same generator and we could easily run SSB and CW on the same band when antennas were separated less then 200 meters. May be other amps are even cleaner but what SPE does is more then enough to me. After all, IMD of 1.3K-FA measured by ARRL (Third-order intermodulation distortion (IMD): 3rd/5th/7th/9th (14 MHz, 1300 W PEP):??? ?31/?39/?57/?55 dB.)? is quite on par with IMD of K3 itself (Third-order intermodulation distortion (IMD) 3rd/5th/7th/9th order (worst case band):???

I did have some issues with the company, but the way they resolved the issues makes me want to recommend them. The first issue was, I wanted a light battery to power a 100W radio, and first ordered a 15 Ah model, based on the website description that it could supply 30A continuous. When the battery arrived, its label indicated a much smaller continuous output capability. Bioenno acknowledged that the website was wrong, and arranged for me to trade up to the 20 Ah model. They said I could try the 15 Ah battery in actual operation before deciding to send it back. I did, and it did no do well at 100W rf out. Once I was set up with the 20 Ah model, I left it on the special charger for weeks between uses. The charger automatically stops charging at full charge, which is indicated by a red/green LED. However, one day I noticed the LED was dark. The charger had died. Bioenno quickly replaced it at no cost. I asked them if it would be better to unplug the charger from the AC when not needed, and they said yes.

Unfortunately we did not find the time to build and test alternative solutions to the P3 and consequently decided against an Elecraft K3S as our radio. However, the K3/K3S still was a very popular radio at WRTC so I did a survey on the WRTC-teams mailing list and asked about their panadapter solutions. My questions were: 1) Did you use the P3 as a panadapter? 2) If not the P3 a) which hardware solution did you choose? - e.g. which SDR/splitter etc? b) which software solution and how did you integrate the waterfall display? - e.g. on a separate PC/monitor or on the same PC/monitor as your logging software? - if on the same PC how did you handle the program focus? c) would you use the P3 if Elecraft added mouse support for point & click? Here is the summary: I got 20 replies in total. 6 used the Elecraft P3 panadapter. 14 went with another solution and chose the following hardware: Airspy HF+: 8 Funcube Pro USB: 2 SDRplay RSP1A: 1 Winradio: 1 Perseus: 1 other SDR: 1 I got less detailed answers regarding the use of splitters: commercial splitter: 1 passive T-connector: 1 no details given: 12 The software used was HDSDR: 4 N1MM spectrum display: 3 Writelog spectrum display: 2 SDR-console: 2 SDR-radio.com: 1 no details given: 2 I received very little information on how to integrate the panadapter. 2 were using HDSDR with the logging PC/monitor and used an autohotkey macro to get the focus back to the logging software. 11 (5 of P3 group, 6 of second group) would use the P3?s mouse functionality if Elecraft added it. The remaining 8 of the second group indicated that their solution, while more elaborate, is smaller, lighter and less expensive than the P3 and they would therefore stick to it. The replies also indicated that the native P3 users were using scope functionality predominantly in a passive way, e.g. watching general band activity and signal strengths. Those aiming to use the scope more actively were looking for solutions providing a fixed waterfall display with mouse support and point & click functionality. This allowed them to more effectively do search & pounce, interleave QSOs or click a new CQ frequency. 73, Stefan DL1IAO, SA3CWW/SM9A -- Stefan v.

Easily solved with any low-pass filter on the K3's ANT1 port (EF Johnson, Nye, Drake, Bencher, countless others). Then use ANT2 for 6m. The multipole LP filters typically have a sharp cut-off above 35 MHz and response is down some 70-80 dB at FM broadcast frequencies. Bencher specs their YA-1 filter -80 dB at 52 MHz with 0.2 dB insertion loss. I went through this very issue with several Ten Tec transceivers. I used a Nye filter that way for 10+ years and it completely cured the problem.

Unfortunately we did not find the time to build and test alternative solutions to the P3 and consequently decided against an Elecraft K3S as our radio. However, the K3/K3S still was a very popular radio at WRTC so I did a survey on the WRTC-teams mailing list and asked about their panadapter solutions. My questions were: 1) Did you use the P3 as a panadapter? 2) If not the P3 a) which hardware solution did you choose? - e.g. which SDR/splitter etc? b) which software solution and how did you integrate the waterfall display? - e.g. on a separate PC/monitor or on the same PC/monitor as your logging software? - if on the same PC how did you handle the program focus? c) would you use the P3 if Elecraft added mouse support for point & click? Here is the summary: I got 20 replies in total. 6 used the Elecraft P3 panadapter. 14 went with another solution and chose the following hardware: Airspy HF+: 8 Funcube Pro USB: 2 SDRplay RSP1A: 1 Winradio: 1 Perseus: 1 other SDR: 1 I got less detailed answers regarding the use of splitters: commercial splitter: 1 passive T-connector: 1 no details given: 12 The software used was HDSDR: 4 N1MM spectrum display: 3 Writelog spectrum display: 2 SDR-console: 2 SDR-radio.com: 1 no details given: 2 I received very little information on how to integrate the panadapter. 2 were using HDSDR with the logging PC/monitor and used an autohotkey macro to get the focus back to the logging software. 11 (5 of P3 group, 6 of second group) would use the P3?s mouse functionality if Elecraft added it. The remaining 8 of the second group indicated that their solution, while more elaborate, is smaller, lighter and less expensive than the P3 and they would therefore stick to it. The replies also indicated that the native P3 users were using scope functionality predominantly in a passive way, e.g. watching general band activity and signal strengths. Those aiming to use the scope more actively were looking for solutions providing a fixed waterfall display with mouse support and point & click functionality. This allowed them to more effectively do search & pounce, interleave QSOs or click a new CQ frequency. 73, Stefan DL1IAO, SA3CWW/SM9A -- Stefan v.

Three years ago, I asked Elecraft about the possibility of point-and-click tuning using a mouse plugged into the USB port of the P3SVGA. These were the key points of Elecraft's reply. 1. "The firmware architecture is arranged to control the P3 from the P3 front panel. The SVGA is controlled by the P3, rather than the other way around." Comment: That does seem to be a substantial technical point, although they also agreed that "anything can be done" (which we must presume to mean, "given sufficient demand and priority"). 2. "You would have to choose between a mouse and a keyboard. The P3SVGA USB does not support... multiple devices at the same time." Comment: Not a deal-breaker. 3. "Is the knob really that much slower than a mouse?" Comment: Words failed me! At that point I broke off the conversation. The gap in understanding was simply too wide. Since then I have purchased a second K3; but I did not purchase another P3. Instead I chose one of SDR-based alternatives which does more, better, at lower cost, and - crucially - continues to evolve. Meanwhile, the P3 falls farther behind. 73 from Ian GM3SEK >-----Original Message----- >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of Stefan von Baltz, DL1IAO >Sent: 26 July 2018 09:53 >To: Elecraft at mailman.qth.net >Subject: [Elecraft] Survey and summary: Elecraft K3/K3S panadapter >solutions > >My teammate and I decided that we wanted to have a panadapter with >mouse support and point & click functionality for WRTC 2018. >Unfortunately we did not find the time to build and test alternative >solutions to the P3 and consequently decided against an Elecraft K3S as >our radio.

I did have some issues with the company, but the way they resolved the issues makes me want to recommend them. The first issue was, I wanted a light battery to power a 100W radio, and first ordered a 15 Ah model, based on the website description that it could supply 30A continuous. When the battery arrived, its label indicated a much smaller continuous output capability. Bioenno acknowledged that the website was wrong, and arranged for me to trade up to the 20 Ah model. They said I could try the 15 Ah battery in actual operation before deciding to send it back. I did, and it did no do well at 100W rf out. Once I was set up with the 20 Ah model, I left it on the special charger for weeks between uses. The charger automatically stops charging at full charge, which is indicated by a red/green LED. However, one day I noticed the LED was dark. The charger had died. Bioenno quickly replaced it at no cost.

I presume you mean the West Mountain ?Epic PWRgate?? This device is designed to use LiPO4 batteries as a power backup for a fixed station operation where 120VAC/power supply (presumably 13.8 VDC) is present to recharge the LiPO4 while providing power to the station equipment. It isn?t clear to me whether the prior posts concern a fixed station use of the LiPO4 or a mobile or portable operation. I?ve suggested to the West Mountain Radio folks (at this year?s Hamcation and Hamvention) that a device that can recharge/manage LiPO4 batteries while mobile would that could power equipment when the vehicle?s engine is off and recharge the LiPO4 while the engine is running would be very helpful as it would keep equipment running during fuel or rest stops, preventing shutdown while also protecting the car?s battery from excessive discharge when operating for more extensive periods with the engine off. An alternator doesn?t provide the stable power that a 120 VAC power supply does and I was advised not to use the Epic PWRgate while mobile. Whether such a device will eventually be developed remains to be seen. Being able to use LiPO4 would significantly extend the amount of time that power could be supplied to mobile electronics as well as reduce the weight of the battery making it easier to install and secure. It would also be useful for portable operation where the LiPO4 battery could be recharged by the car?s alternator while in transit to the next portable operating site for use outside the vehicle (such as a KX2 or KX3 portable setup) or while parked using installed equipment. In the meantime, I?m using a 12VDC 7AH AGM with West Mountain Radio?s ?ISOpwr? to manage power to my mobile electronics, including USB Hubs to power various USB devices as well as mobile rigs. Keeping the USB devices powered during engine shutdowns for refueling is critical as it eliminates the need to reboot the laptop mounted in the car that is connected to a GPS receiver, 8 iMICS, and several RTS-3 USB-to-Serial adapters. If any of these devices lose power from their respective hub due to engine shutdown, it requires a reboot of the laptop to re-establish connection and restart of the various applications that utilize these devices to get everything going again. 73, Barry, WD4ASW > ______________________ > Clay Autery, KY5G > (318) 518-1389 > From htodd at twofifty.com Thu Jul 26 13:27:57 2018 From: htodd at twofifty.com (Hisashi T Fujinaka) Date: Thu, 26 Jul 2018 10:27:57 -0700 (PDT) Subject: [Elecraft] Elecraft SW (and wsjt-x) on Ubuntu 18.04 anyone?

Please visit the Elecraft K3 software page (www.elecraft.com/K3/k3_software.htm) to obtain our free firmware download application, the K3 Utility. This program runs on PCs, Macs, and Linux platforms.? The document on page 22 also explains how to determine the unit?s firmware and serial number: "Use the K3/0, K3/0-Mini or K3 CONFIG menu?s FW REVS menu entry to determine your firmware revision. The serial number of your K3/0, K3/0-Mini or K3, if needed, can be obtained using the SER NUM menu entry. This is the serial number of the K3/0, K3/0-Mini or K3 at the control site. It is not the serial number of the equipment used at the remote site.? By ?remote site? this is defined as the K3 that the K3/0 or K3/0-Mini is connected and the ?control site? is where the operator is located (K3/0 and K3/0-mini). See ?List of Terms? on page 4 of the ?K3-Remote Owners Manual.? Since the ?K3-Remote Manual? is now over four years old and an updated document has not been released, it would also seem that the firmware installed on the K3/0-Remote devices hasn't been updated. That said, the manual does not clearly state whether a separate firmware package is used by the K3/0 and K3/0-Mini versus the K3/K3S. The wording could be interpreted to suggest that the same firmware package is used for both the ?Remote? and ?Control? devices. Perhaps Wayne, N6KR or Don, W3FPR can clarify this for us. 73, Barry Baines, WD4ASW > On Jul 26, 2018, at 11:27 AM, Hisashi T Fujinaka wrote: > > Did you hear anything?

Just connect the PC directly to the COM port and the K3 Utility will recognize and update it.th n Thanks for the clarification on updating the K3/0 or K3/0-Mini firmware by using the K3 firmware. Question: Once you updated the K3/0 or K3/0-Mini with new firmware, did you notice any changes in capabilities of the ?control site? equipment (K3/0) or compatibility with the K3/K3S ?remote site? equipment (which presumably has newer firmware as well)? I ask because I?ve been fairly diligent about updating the K3 firmware from time-to-time but haven?t updated my K3/0-Mini devices at all (I have a device at two different locations). The oldest K3/0-Mini was purchased in August 2014. I?m wondering how critical the updates are to the ?K3/0? devices. From what I can tell, the K3/K3S firmware revision documentation doesn?t differentiate between features that impact the K3/K3S versus what impacts the ?K3/0? devices. 73, Barry, WD4ASW > > 73, > Mitch DJ0QN / K7DX > > -- > Mitch Wolfson K7DX / DJ0QN > 10285 Boca Cir, Naples, FL 34109 > Skype: mitchwo > USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 > Germany: Home:+49 89 32152700 - Mobile:+49 172 8374436 > From lists at subich.com Thu Jul 26 18:33:34 2018 From: lists at subich.com (Joe Subich, W4TV) Date: Thu, 26 Jul 2018 18:33:34 -0400 Subject: [Elecraft] Survey and summary: Elecraft K3/K3S panadapter solutions In-Reply-To: <1532640487146-0.post@n2.nabble.com> References: <9866137a-a8af-504a-4f2b-8a312e416ac6@wc2l.com> <1532640487146-0.post@n2.nabble.com> Message-ID: <0009d98f-a6d2-7f3e-fba3-3b30c873cc28@subich.com> The issue is that NaP3 does not support Airspy, SDRplay or RTS dongle based SDRs.

Firmware updates have slowed way down over the last few years, but there were a number of enhancements made within the period following the release of the original K3/0 and then K3/0 Mini that required to update both sides and keep them in sync. I can't remember the details or why, but Wayne or Eric would remember. I still do my best to maintain them in sync, although this may no longer be as critical as it was in the past (I am not into taking risks and it only takes a couple of minutes). 73, Mitch DJ0QN / K7DX -- Mitch Wolfson K7DX / DJ0QN 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile:+49 172 8374436 On 26.07.2018 22:39, Barry Baines wrote: > Mitch: > > >> On Jul 26, 2018, at 3:45 PM, Mitch Wolfson DJ0QN / K7DX > > wrote: >> >> Dennis and Hisashi, >> >> I have updated my K3/0 from time to time using the newest firmware >> for the K3.

Switch it on and connect your SDR of choice to the IF out connector. I have an SDRplay RSP1 connected to mine which allows use of the spectrum facility in Win4K3, N1MM and DXLabs on the big screen as well as the P3. Being an RSP1 you can of course use any of the software that supports it. Set aside a good bit of time, it's quite a rabbit hole and getting the settings just right is not always trivial.

The principles of how antennas work. RF current flows on BOTH the center conductor and shell of that BNC connector. It's a simple series circuit. The wire you CALL the antenna provides only half of that circuit -- a counterpoise, the other half of the antenna, provides a return path. We could, of course, connect it to a ground rod, but that causes the earth, which is a (very) big resistor, to be the return path, so it can burn (much) of the TX power. Far better to use a length of copper wire (a quarter wave is ideal) to carry that return current. A connection to mother earth is an important part of lightning protection.

It is used for an AC Safety ground and provides some measure of protection from lightning. If you connect it to a shack ground rod, that rod must be connected to the utility entry ground rod by a heavy (#4 or #6) wire on the outside of the building. If you cannot connect it to the Utility Entry Ground, it is my opinion that the K2 (and other shack gear) is better of left not connected to ground. 73, Don W3FPR On 7/27/2018 2:03 PM, Mark Petrovic wrote: > Oh, I see.?

This is not an option. ALL grounds within a building MUST, BOTH BY LAW, and by good engineering practice, be bonded together. Failure to do so is to INVITE lightning damage. 73, Jim K9YC From turnbull at net1.ie Fri Jul 27 15:16:38 2018 From: turnbull at net1.ie (Doug Turnbull) Date: Fri, 27 Jul 2018 19:16:38 -0000 Subject: [Elecraft] "The Elecraft Story" In-Reply-To: References: Message-ID: <0F7C0C7521614F33A02EA7AD747B7CBB@DougTPC> Hello Roccon, This was an interesting piece and most appreciated.

I believe the K3/K3S, KX3 and KX2 already qualify as SDR transceivers - but they do the DSP signal processing inside the box without any dependency on an external computer. Some seem to think that to be an SDR, you must connect with a computer - I do not share those thoughts, an SDR is all about mathematical processing - study a bit on DSP, that is "what it is all about". I and Q signals can be defined as 2 identical signals but 90 degrees out of phase - period (full stop there, anything more is what adds confusion). One can do "magic" with those two signals, and create filters, demodulate, modulate - all by manipulating the signals in the digital world. It can also be done in the analog world (examples, Rick Campbell's phasing receivers, and the old phasing SSB exciters) The K3/K3S does have I/Q signals, but they are digital and are at 15kHz, not audio, so one cannot feed them to a computer soundcard. The KX3 has I/Q signals (and I/Q outputs) because the I/Q signals are at baseband (audio frequency spectrum). The onboard computer (MCU) inside the radios do the processing rather than depending on a computer soundcard and the computer MCU for the processing. The KX2 is similar, but has no I/Q outputs. While some want to add their favorite computer software application to do I/Q processing separate from that done by the K3/K3S or KX3 or KX2. The current fact is that the K3 I/Q signals exist, but they are only in the digital world. The P3 does extract them, but for purposes of the P3, they remain in the digital world. Getting those signals into the analog world will take some work and design effort. It is more complex than a digital to analog converter. 73, Don W3FPR On 7/27/2018 5:17 PM, Dave Fugleberg wrote: > As I understand it, the KX3, and the P3, both contain a software defined > receiver, so the I/Q signals are already present. > > That is not the case for the receiver in the K3 or K3S, so adding it there > would involve adding a SDR. > On Fri, Jul 27, 2018 at 2:21 PM Dick Dickinson > wrote: > >> Ever the contrarian here, I note the KX3 has I/Q output.

I am using a 12 ele K1FO yagi - about q12 dB gain on 2. That enters the shack where it is connected to a Downeast Microwave 50 Watt transverter with about 17 dB gain on receive. The output of the transverter is connected to transverter input on my old K-3. For the longest time, I was receiving loud QRM from what I initially thought were power line noise bursts. But, I became suspicious because these bursts were about a second or so in duration consistently. During this time, I was testing my setup for meteor scatter using the MSK 144 software found in the current WSJT-X suite. These loud bursts created huge red images on the monitor watching in 144.150 MHz, the MSK144 calling frequency. I got suspicious that these signals were not simple electrical pole shorting noise. So, I connected a whip to my old TS-790S rig and tuned it to 144.390 MHz, the North American APRS frequency. WALAAAAA, the signals on my monitor connected to a K-3 tuned to 144.150 MHz corresponded perfectly to the WPRS signals on 144.390 MHz, some 240 kHz away! The preamp on the K-3 was off. There were no other receiving preamps in line at the time. Later, I turned on an external 2 Meter preamp and all that happened was that the APRS signals were larger at 144.150 MHz. It appears that the front end of my K-3 simply folds up in the presence of strong signals that are WAY off the receiving frequency. I can tell you that connecting the same antenna/transverter to a Kenwood TS 590SG, there were no traces of the APRS signals. And connecting the TS-790S to the K1FO likewise produced no APRS QRM at 144.150. To me, with the presence of a number of strong APRS signals on 144.390 makes this K-3 extremely unusable on 2 Meters. I was running the K-3 noise blanker to handle the rest of the noise here but likewise, I also had noise blankers running on the two Kenwood radios as well. Any suggestions are welcome.

If so, what band -- 10 meters? It makes no sense that the K3 would have difficulty with out of band signals in the manner you describe. It has far better dynamic range on all bands, including 10 meters, than the TS-590.

The hardware blanker does see a broad input frequency range (so it can suppress very fast-rise-time noise pulses), and as with similar blankers, you have to keep the NB threshold high enough to not cause intermod. Try using just the DSP blanker, which is post-crystal-filter. Or a touch of each. This can be very effective on disparate noise sources.

I did the alignment with Spectrogram. A few of the filters were off, and I corrected them. However, it didn't make much difference in improving SSB intelligibility. I then realized that the KDSP2 might be introducing artifacts to the audio. I turned the denoiser off, and the audio was much better, but the noise was unbearable. I was gong to play with the various settings, when I remembered there were many differing opinions on how to set them up properly, and I think the conclusion was that the factory settings should be used. Did I recall correctly? If that's the case, can you share them with me? I might have mucked them up a long time ago. 73, Dan KF4KKF ________________________________________ From: Don Wilhelm [donwilh at embarqmail.com] Sent: Sunday, July 22, 2018 2:04 PM To: Pawlak, Daniel L; elecraft at mailman.qth.net Subject: [EXTERNAL] Re: [Elecraft] K2 audio problem Dan, Align the IF filters. I have no idea what may have made them change, unless you tried to do a Master Reset which would change the filter settings back to factory defaults, which only work well in a few K2s. It is best if you use an audio spectrum analyzer running on your computer to see where the filter passband is located in the audio spectrum.

There you will find links to Spectrogram version 5.17 and version 16. These files are local to my website. If you did a Master Reset, also refer to the K2 dial Calibration article on my website. You will have to do a CAL PLL in addition to the filter alignment (CAL FIL). Advice to all - do not do a K2 Master Reset unless you first record ALL your menu settings, including the Filter settings. The first few pages of the K2 A to B upgrade instructions has instructions for recording all you menu settings. Restore them after a Master Reset. 73, Don W3FPR On 7/22/2018 1:36 PM, Pawlak, Daniel L wrote: > I'm having trouble figuring out what's wrong with my K2 (serial 3957).

I agree with Wayne that a noise blanker is responsible for what you are seeing. FWIW, what these two blankers are CALLED in their setup menu (long push of NB) is VERY confusing. Fact is, that they are BOTH working in an IF, one in the first IF and the other in the second. FAR better to call them IF1 and IF2. NOW it becomes clear which is post-xtal filter. How we talk about something makes it either easier or more difficult to understand. That's why I strongly object to use of the word "balun," which is used to describe almost a dozen VERY different THINGS, and multiple meanings of the word "ground," all of them very different from each other. Another is the phrase "ground loop." All three uses often cause people to do really dumb things to solve a problem because the words don't describe what is really going on! 73, Jim K9YC From billamader at gmail.com Sat Jul 28 03:24:51 2018 From: billamader at gmail.com (K8TE) Date: Sat, 28 Jul 2018 00:24:51 -0700 (MST) Subject: [Elecraft] "The Elecraft Story" In-Reply-To: References: Message-ID: <1532762691404-0.post@n2.nabble.com> Wayne's brief history of Elecraft was great to read.

The output of the transverter is connected to transverter input on my old K-3. For the longest time, I was receiving loud QRM from what I initially thought were power line noise bursts. But, I became suspicious because these bursts were about a second or so in duration consistently. During this time, I was testing my setup for meteor scatter using the MSK 144 software found in the current WSJT-X suite.

So, I connected a whip to my old TS-790S rig and tuned it to 144.390 MHz, the North American APRS frequency. WALAAAAA, the signals on my monitor connected to a K-3 tuned to 144.150 MHz corresponded perfectly to the WPRS signals on 144.390 MHz, some 240 kHz away! The preamp on the K-3 was off. There were no other receiving preamps in line at the time.

I can tell you that connecting the same antenna/transverter to a Kenwood TS 590SG, there were no traces of the APRS signals. And connecting the TS-790S to the K1FO likewise produced no APRS QRM at 144.150. To me, with the presence of a number of strong APRS signals on 144.390 makes this K-3 extremely unusable on 2 Meters. I was running the K-3 noise blanker to handle the rest of the noise here but likewise, I also had noise blankers running on the two Kenwood radios as well. >> >> Any suggestions are welcome.

You're can almost never tune in someone perfectly just by clicking, and you shouldn't need two hands to tune in a station, one on the VFO knob, and one on the mouse. A mouse driver for the P3SVGA could be very simplified. It does NOT have to work like a mouse on a PC. Like the P3 VFO "markers," all a mouse needs to support is *horizontal movement* of a single vertical line when you move the mouse, not a fancy mouse pointer that goes up and down. A vertical line is sufficient. We only need to click on signals on the waterfall, not "buttons" or "menus". This is what I'm expecting to see from the P3SVGA mouse support: Left click: Move VFO A to clicked freq. Right click: Move VFO B to clicked freq. (for DX split pileups) Scroll Wheel: Fine tune VFO A, B, or "last-clicked" (user option) Scroll Wheel Up = move VFO up in frequency Scroll Wheel Down = move VFO down in frequency I understand that modern Icom radios (IC-7610, IC-7851) already support click-to-tune on their waterfall displays using a USB mouse or touch-screen tap, but they ignore the scroll wheel completely, making them much less useful. Elecraft can and should do better. If Elecraft needs to "monetize" this to make it happen, *I would gladly pay $50 for a P3 firmware upgrade that provides P3SVGA mouse support.* Next best would be *P3SVGA K-POD support*, K-POD connected to P3SVGA via USB, used instead of the tiny P3 knob and awkward knob push, but maybe that's not feasible due to hardware limitations. 73, Bob, N6TV From ve7yc at shaw.ca Sat Jul 28 10:02:50 2018 From: ve7yc at shaw.ca (Ronald Stunden) Date: Sat, 28 Jul 2018 07:02:50 -0700 Subject: [Elecraft] Re Message-ID: I saw an add for what looked like a baase loaded antenna for the KX3, Now I can?t find it.

I like the P3 for Search & Pounce in RTTY contests, but it's very tiresome to use the QSY knob on the P3. Rather than using the P3 marker/QSY function, I found I could get similar results by using VFO B, A/B, and A>B on the K3, but that's tiring as well. So, I gutted out an old optical mouse except for the switches and scroll wheel/encoder, and stuffed an Arduino Nano inside. The Nano's USB port is plugged into the computer and assigned to one of the virtual ports of Win4K3, so it looks like a serial CAT device to the P3/K3. The Arduino's code has two states: Hunt and Devour. The Right button puts it in Hunt mode, where the scroll wheel adjusts VFO B. I scroll VFO B to the next RTTY signal on the band while working one on VFOA. When my QSO is done, a click of the wheel puts it in Devour mode. This executes A/B, then A>B, so both VFO are now on the new frequency. In this mode, the scroll wheel controls VFO A for fine tuning to zero in and devour the prey. Once I start that QSO, I click the right button to enter Hunt mode, and the cycle repeats. I call this gadget the RTTY Kitty, or the CAT-n-Mouse. Of course, general purpose mouse support on the P3 would be much more versatile, but this works pretty well for the specific purpose I had in mind, and it was fun to do. I suspect something similar could be done with a KPod, but I don't have one, and dead optical mice are plentiful. 73 de W0ZF On Sat, Jul 28, 2018 at 9:01 AM, Bob Wilson, N6TV wrote: > When Elecraft adds mouse support to the P3SVGA, please use the scroll wheel > for fine tuning after the click, as one does on an SDR.

Remote users can already do what you're requesting using a video capture card connected to the P3SVGA, Win4K3suite, and TeamViewer or equivalent: See this thread: http://elecraft.365791.n2.nabble.com/SVGA-capture-td7636918.html Remote P3 performance may be questionable (too slow for spectrum display probably). For those of us who need to keep the mouse pointer focused on our contest loggers, clicking on another PC window is not ideal (logger loses focus). Despite workaround hacks, I'd still prefer the separate standalone P3SVGA + mouse hardware. Yes, some loggers like N1MM+ have integrated it all in one window if you have an SDR, but for various reasons I prefer a different contest logger (Win-Test). For years I've used a Perseus SDR + HDSDR + OmniRig + Win-Test to get click-to-tune support on one display, but my logger loses focus when I click on the waterfall, so I'd really prefer a separate mouse and display. See my short presentation "Adding a Software Defined Radio (SDR) to an SO2R station", the very last link on the bottom of my QRZ.COM page , for screen shots of the current click-to-tune technique that works with any supported SDR + K3. 73, Bob, N6TV On Sat, Jul 28, 2018 at 9:04 AM, John K9UWA wrote: > Clay think about those of us who operate our stations remotely.

A significant amount of firmware is required at the P3 end, but we?re definitely looking at this.

I had to send my K3s to Elecraft for repair. I purchased a K3 a couple years back to set up for a close friend and though it has all the factory updates, it had a low serial # and he wanted one with a high one. I sold him my equally updated K3 with a higher Serial # and kept this one. It has sat on the shelf as my backup radio for the last two years I rarely use SSB, only CW & have maybe 3-4 SSB conversations/year. With the remote preamp attached it became problematic to the wiring and to simplify things I updated the K3 with the new KXV3B and KIO3B boards so it will match the connections of the K3s and simplify wiring issues and not need an external soundcard. I found I could not transmit with WSJT-X but I could receive and decode just fine, CAT and Test PTT worked perfectly, clicking on tune showed the K3 led red as in transmit but zero output regardless of line level or power out adjustment. The DATA MD is indeed set to DATA A. The computer sound settings showed the K3s USB was selected for default and the levels were both at 52. I exhausted all I could think of to do to get it to work but nothing out. However, the K3 transmitted perfectly in CW and the auto-tuner worked as expected. I discovered later that the K3 will not transmit in SSB. In AM it sends out the carrier appropriately proportional to the power setting but nothing of audio was transmitted. There is nothing plugged into the back of the K3 in the audio/line KXV3B I/O module. I loaded the config from two years ago when I brought it home and after changing the config to see the new components there were no changes in SSB transmission. I did a full EE factory reset, re-set the configuration to reflect the new K3s boards and still no SSB out. Since WSJT uses SSB to transmit, I assume this is the cause of no transmit with that software (it worked fine with the K3s). One assumption is the K3 I bought has a defective component from when I bought it and I didn't know that because I didn't try SSB. I thought I had while setting it up for my friend (now SK) but it was awhile ago and I don't remember if I did or not. ----- So with all the history above, has anyone had an issue like this that you found the resolution to? Maybe there is some setting in the K3 I need to engage? There's nothing to unplug from the rear and everything else works perfectly. Ideas & suggestions?

Diddeling with the mic gain does nothing. I used the ALC out of the rig to control the power. Here is my tune up procedure. SSB mode, tune the final stage for maximum output. Send a tone and adjust the power output by setting the ALC voltage from the 520. I normally tuned for 25W on an external meter. Max ALC voltage is -9V. I built a box, yes Altoids, with a 9V battery and a 10K linear taper pot. The pot MUST be linear taper. Then it's just proper wiring. The point being you must tune the rig as if you were going to use SSB including setting the mic gain where you normally use it. Don't monkey with it. My PSK meter said I was doing -35dB. Lets see ya do that with a 12V final solid state rig. R.

You might be able to reduce output by winding back the mic gain but it will likely sound a bit "thin" and any loud noises over an above nominal speech will produce more output. When you set the carrier or drive control that only has an effect on the CW output, it doesn't set the SSB output. I recall a common way to limit the output of these radios in SSB mode was to feed a dc voltage into the external ALC input of the rig in order to have it reduce power.

It works in the number soup which is after the high IF, *and* after the low IF, *and most importantly* after the analog to digital conversion. DSP NB, being accomplished in the number soup, is not restricted to the limits of analog methodology. While the signal being corrected is *representative* of the low IF, it is not accomplished *in* the IF circuitry and is subject to any outcomes of the analog to digital conversion. A good rule for using the IF labeled NB in the K3, is to only use it if it makes NB on ***that particular noise*** work better, otherwise don't use it at all. Some of the noise I have around here from time to time is better blanked with IF + DSP. Other noise is blanked better, sometimes much better, by DSP only. I'm to the point now where I know what each noise around here sounds like and can put up the best NB settings right away. Also some combo's that work well on 160 work poorly on 80m and up. For the new user of K3 NB, remember that METHODS are also being switched as you turn the knob, it's not at all like a simple 1 to 10 scale. You can use a (1st) IF method, and a DSP number soup method, or IF only or DSP only. When you use both methods, they operate separately in series, with the IF method necessarily being applied first. It appears, to me at least, that some DSP methods are diminished by running the IF blanking at the same time. For 2 and a half years I had an AC pulse noise on 160 that IF NAR4 + DSP T1-7 or T2-7 cleared out to below the band noise in a certain 5-6 kHz range and less efficiently away from that. Contest operation in that range was equal to no pulse noise. It turned out to be leakage in a splice in the 13kV buried line to easterly neighbors' power transformer. When the splice hard arced this spring, that noise went away and has never returned. The fuse blow up on the feed pole across US 64 sounded like a bomb. It rattled windows. They replaced all the buried 13kV line off that aerial 13 kV feed to our transformers. Noise has never come back. Currently the IF blanker is not useful for any noise I run into here. That could change, of course, at any time :>)) 73, Guy K2AV On Sat, Jul 28, 2018 at 12:10 AM, Jim Brown wrote: > .

What an awesome place! It feels like a coastal tourist paradise in another country, except that it?s just 26 miles from Long Beach. Definitely a bucket-list item. To recover from two days of gawking at beach scenery and tapping generous libations, I set off on a 6 mile solo hike to take in the view from 1500 feet. And to sneak in a little stealth radio op. From downtown Avalon I walked to the Wrigley Memorial, then zig-zagged up the Garden to Sky trail for 1.2 miles, where I was rewarded with a vista to the north that includes another of the Channel Islands. At this point I picked up the jeep road for another half mile, heading east, ascending even further to a gazebo overlooking the Hermit Gulch campground far below. (The trail down from here is very steep; if I ever do it again, I?ll go the opposite direction.) This gazebo was the perfect spot to break the KX2 out of its tiny ES40 bag and deploy the whip, which took all of 30 seconds. Aside from the obvious (gorgeous WX, killer view, and the joy of running 10 watts hand-held to an AX1 whip on 15/17/20), I was blessed with both acoustic and RF noise floors so low that I was reminded of a minor tinnitus condition. No wind, no other humans, the occasional cry of a hawk, and the radio equivalent of a peaceful, easy feeling. I could hear stations that were merely thinking about transmitting. It would be tempting to weave a tall tale about DX worked from this idyllic overlook. Truth is I just listened for awhile, marveling at how sparkling clean everything sounded without the usual three coats of RF grunge we often suffer at home. The noise drops with any trip away from civilization, of course, but this was exceptional. It?s yet another reason to get out of the shack.

A couple of other tips: 1. A small amount of NR (noise reduction) can be used along with the noise blanker to perform a bit of signal clean-up. 2. Most of us run with too much gain and/or too much AGC, in some cases making it sound like the noise blanker is doing less that it really is. I strongly recommend starting with preamp OFF and experimenting with AGC off as well to really hear the effect of the NB. 3. If you?re using CW, crank down the WIDTH control and also try APF. This can remove even more noise with zero signal degradation. (The APF works wonders on weak signals near the noise floor.) 73, Wayne N6KR > On Jul 28, 2018, at 10:17 AM, Guy Olinger K2AV wrote: > > Although I agree with other points, the DSP noise blanking does not work by > pulse-closing the analog 15 kHz IF.

Set the audio level correctly first and you will have no problem. For soundcard data modes (I don't care which one), set the audio so you have 4 bars solid on the ALC meter and the 5th bar flashing.

I am looking hopefully at the Nanuk case holding my KX3. No AX1 to complement it, but here's hoping the wx holds at least partially this week for a side trip to somewhere like Delaware Seashores State Park for a bit of the Right Coast version of that kind of op.

If you already have a KX3 that you normally only use for portable operation, you might give this idea a try. The output from the KX3 is wideband (~200 kHz) analog I/Q, not digital, but that?s fine if your computer has a high-performance sound card interface. The KX3 will work well in this application since it has very good RMDR (receive mixing dynamic range) thanks to its low-noise synthesizer, strong mixer, and front-end band-pass filtering. Recommended one-time setup: 1. Connect the KX3?s antenna input to the rig?s IF OUT jack (standard on the K3S; comes with the KXV3 option on the K3). 2. VERY IMPORTANT: Set the KX3?s power output to ZERO watts to avoid problems should you accidentally transmit into the IF OUT jack. The IF OUT jack does have a carrier-operated relay, but we?ve already tested it. You don?t need to. 3. Use FREQ ENT on the KX3 to set it to 8.215 MHz, matching the K3/K3S IF. This will switch the KX3 to the 40-meter band. 4. Other recommended settings at the KX3: - Set mode to USB - Normalize the filter passband (NORM) - Turn the preamp on to ensure a good noise figure driving the computer?s panadapter or other application - In the menu, turn RX ISO ON, set PREAMP gain 20 dB, and make sure RXIQ is ON. - Set rig?s AF GAIN to 0 (you won?t be listening to the signal on the KX3, though you could, just for fun) 5. Connect the RX I/Q jack on the KX3 to your computer sound card input. 6. Run your favorite software application(s) that need I/Q data. (Note: If you see symmetrical signal images in a software-based panadapter display, chances are the RX I/Q connector isn?t fully plugged in at the KX3 end.) 7. The above setup may require additional tweaking depending on what applications you?re using. You might need to adjust the KX3?s VFO frequency to match the crystal filters used in the K3/K3S, for example. Since the KX3 itself can be controlled from a software application over USB, it would be easy to automate settings using a bit of custom software. If you try this, please post your settings and results to the list for the benefit of others. We might summarize things in an application note. It?s an excellent use of any KX3 that?s otherwise stashed away in a go-bag. 73, Wayne N6KR From john at kk9a.com Sat Jul 28 15:21:03 2018 From: john at kk9a.com (john at kk9a.com) Date: Sat, 28 Jul 2018 15:21:03 -0400 Subject: [Elecraft] KPA-1500 Power Supply Cable Size Message-ID: <005901d426a8$20cffd90$626ff8b0$@com> The 75 amp Powerpole connector is designed for 6, 8 or 10 AWG wire so you might have problems squeezing a larger wire in.

I'd trim down the end of the conductor to JUST fit into the 75 AMP crimp contact. Then, I'd tine the trimmed down end to bond ALL the conductors together right at the end before I crimped/soldered. Then, I'd crimp/solder the terminal on making sure not to be sloppy and cause a fitment issue. If possible, I would put as many twists in the red/black leads between radio and power supply connection as possible.... I've not investigated the wiring yet, BUT, if there is a ground wire between the PA chassis and the PS chassis, I would integrate the ground wire into the power harness in a 3-wire bundle with all three wires as close to the same length and shinked into a single cable.

What an awesome place! It feels like a coastal tourist paradise in another country, except that it?s just 26 miles from Long Beach. Definitely a bucket-list item. To recover from two days of gawking at beach scenery and tapping generous libations, I set off on a 6 mile solo hike to take in the view from 1500 feet. And to sneak in a little stealth radio op. From downtown Avalon I walked to the Wrigley Memorial, then zig-zagged up the Garden to Sky trail for 1.2 miles, where I was rewarded with a vista to the north that includes another of the Channel Islands. At this point I picked up the jeep road for another half mile, heading east, ascending even further to a gazebo overlooking the Hermit Gulch campground far below. (The trail down from here is very steep; if I ever do it again, I?ll go the opposite direction.) This gazebo was the perfect spot to break the KX2 out of its tiny ES40 bag and deploy the whip, which took all of 30 seconds. Aside from the obvious (gorgeous WX, killer view, and the joy of running 10 watts hand-held to an AX1 whip on 15/17/20), I was blessed with both acoustic and RF noise floors so low that I was reminded of a minor tinnitus condition. No wind, no other humans, the occasional cry of a hawk, and the radio equivalent of a peaceful, easy feeling. I could hear stations that were merely thinking about transmitting. It would be tempting to weave a tall tale about DX worked from this idyllic overlook. Truth is I just listened for awhile, marveling at how sparkling clean everything sounded without the usual three coats of RF grunge we often suffer at home. The noise drops with any trip away from civilization, of course, but this was exceptional. It?s yet another reason to get out of the shack.

The directional bridges/couplers in most "(V)SWR" meters that hams routinely use externally or which are built into our radios are not precision instruments.? There are a number of error sources in reflection measurements; source match, diode non-linearity, coupler tracking errors and often the most significant, directivity error. In an ideal coupler, (i.e signal separation device) one port measures the forward (incident signal) and another measures the reverse (reflected) signal and there is no coupling between ports in the unwanted direction(s).? In other words there is no signal at the reverse port due to the forward signal.? In a real world coupler there is some leakage signal appearing at the reverse port due to the forward signal, absent any reflected signal.? The "goodness" of a directional coupler in this instance is called "directivity" and the error signal is directivity error. Directivity is usually specified in dB.? Really good couplers might have directivities in the 40 dB neighborhood.? Really really good directional bridges can be 50 dB, but so-so units might be 25-30 dB.? Not ready for prime time units are lower than this. Now I have no way of knowing what the directivities are of the couplers built into K3s, KPA500s, KAT500s, etc. but considering that they have to work over about 5 octaves, I'm going out on a limb and saying that 25 to 30 dB is a fair estimate.? If I'm wrong, I'm sure I'll hear about it.? For sake of discussion I'm going to use 26.5 dB.? What this means is that if I terminate the output spigot of one of these radios with a perfect 50+j0 load, I'm going to measure a leakage signal (directivity error) that is 26.5 dB below the incident value.? I'll introduce the concept of return loss here. We hams usually speak in terms of SWR.? SWR = (1 + p) / (1 - p) where p is the reflection coefficient. Here the p = the voltage measured at the reflected port and the constant 1 represents the incident signal.? In reality both of these quantities are complex numbers, they have both magnitude and phase but SWR measurements are scalar, we throw away the phase (since it's difficult to measure) and just use the magnitude. (In fact the symbol "p", which is really the Greek letter rho, indicates the magnitude of the reflection coefficient in normal usage)? We can also express this ratio as return loss, which is -20 * log10(p).? So return loss, SWR and reflection coefficient are just different ways to express the same thing; the ratio of incident to reflected signal. Let's return to our example; the coupler with 26.5 dB directivity, which indicates a return loss (RL) of 26.5 dB even with a perfect termination.? Doing the math and converting RL = 26.5 dB to SWR we get 1.1:1.? Our perfect load measures 1.1:1 with our imperfect instrument.? And this assumes that there are no other errors, which there always are. But it gets worse. Let's say that the load we want to measure really is 1.1:1.? We now have two (apparent) reflections, 1) the real one and 2) the directivity error and they both have the same magnitude.? In our simple detector, they sum together.? Now I said earlier that we don't measure phase, only magnitude, but just because we don't, or can't measure the relative phases doesn't mean they aren't there. We will examine two cases to determine the limits of error.? Case 1) both reflections are in phase, they add up to p + p or 2p, RL = 20.5 and SWR ~1.21:1.? Case 2) they are exactly out of phase, they sum to zero.? p = 0, RL is infinite and SWR = 1:1.? The possible RL error is then -6 to +infinity dB! In other words, an actual SWR of 1.1:1 can be measured anywhere between 1.0:1 and 1.2:1.? Is it any wonder that we often read about concerns that one device measures one thing, while another located at the same, or close location measures something different.? Of course all of this is predicated on a directional coupler with 26.5 dB directivity and no other error sources.? It's entirely possible that the Elecraft couplers are better than this.? They are certainly no better than 40 dB since the internal reference resistors are 51 instead of 50 ohm.? Plus the "Tandem Match" configuration is in itself not a great match to the transmitter output.(1)? Furthermore, the coupler, at least in a K3 is driven by a LPF, which isn't a great 50 ohm source. Plus the coupler output port isn't connected directly to the coax connector..... and so on and so forth (2).? All of this creates "uncertainty." In a metrology lab heroic efforts are made to reduce uncertainty but do we, or should we, really care in this situation?? In my opinion, no, but everyone is free to differ. Wes? N7WS (1)?

Where to begin. All was going well until "installing" U1 MAR-1 MMIC. Initial inventory of said kit was missing U1 MAR-1 MMIC. FWIW, there are no part numbers and no pictures in the pdf manual. So I emailed parts at elecraft and they sent me E600080 MAR-1 MMIC in a plastic bag. Upon inspection of this part during the build 2 weeks later it did not look like a solderable part, there were no leads for the thru holes. It appeared to be just plastic with a raised "+" on one side and two holes on one end. So I emailed parts at elecraft and said there has to be a mistake/problem and could they please check again and send the correct part that was solderable. I received the second E600080 MAR-1 MMIC. Meet the new boss same as the old boss... the parts were identical. Upon closer inspection under magnification there is a "part" located inside the "+". So cut it out and it is a very small black cylinder with 4 "arms" 90deg apart. If this is the correct part then I'll send back the first one they sent me. But here is the problem. The Ngen PCB Rev B (which is the PCB that I have) has 4 "thru holes" for installing U1 MAR1 MMIC and there are no leads from E600080 to solder it to the PCB. There are 4 "arms" but it is unclear to me how these "arms" are to be soldered to the board. Unless I solder wires in the 4 thru holes in the PCB and thence to the "arms" of E600080 I have no idea how to solder this part to the PCB. The pdf manual does not say anything about soldering wires into the thru holes and thence to the "arms". http://www.elecraft.com/manual/E740057_N-Gen_Manual_Rev_D.pdf I'm hoping someone else has built this module kit lately and figured it out or Elecraft is going to have to give me some guidance on how to solder this part to the board because it sure is not obvious to me.

Because you all cared enough to offer help, I went back over this problem today and have some answers. First of all, Wayne, Jim and Guy were on the money regarding the NB. But first, let me go back a bit. I was listening on 144.150 mHz upper side band; no preamp on with the K-3. No other preamp in line. I am using the K-3 as an IF for a new Downeast Microwave 2 meter transverter. This transverter offers about 17 dB receive gain to the K-3 at 28 mHz, the IF frequency. The transverter is connected to a K1FO yagi with about 12 dB forward gain. The line audio output of the K-3 was patched to the mic input of a Dell PC that was running MSK 144, a program in the WSJT-X suite of software, and I was testing the system to run in upcoming meteor showers. Suddenly, I was interfered with by APRS local signals transmitting at 144.390 mHz. Everyone was very helpful in making me understand how the two noise blankers in the K-3 work. Your comment, Jim, about calling them NB1 and NB2 is absolutely correct! This is what Kenwood does on their TS-5909SG radio. So, I tuned the TS-790S to 144.39 mHz and being a Saturday, there was plenty of activity. The local APRS station that is closest to my QTH must be really close because he pins the S meter on the 790S connected only to a mobile whip in my steel building. That is the signal that appears at 144.15 mHz on my K-3. APRS is FM and I assume that these signals are generated by a transmitter operating in Class C. Just looking at the signal on my monitor that is printing the activity on 144.15 mHz, it looked pretty dirty. And I am listening on upper side band. There is a large signal entering the transverter input port on the K-3, given the antenna gain, the receiver gain of the transverter and the large APRS signal. Operating the noise blanker control on the K-3, I discovered that at EVERY setting level using the IF noise blanker, the APRS signal was not just leaking through but was really strong on 144.15 mHz. (Sorry, I was not able to quantify ?really loud?, but you get the picture) There was no way to eliminate these APRS signals by changing AGC or eliminating AGC. Then, I turned off the IF noise blanker and turned on the digital noise blanker. It not only eliminated the APRS QRM at 144.15 mHz, but, it also eliminated much of the power line noise. I ended up at T3-5 setting as best. So I am pretty happy now. I just need to confirm that the digital filter setting does not distort SSB signals by being too aggressive. Here is my question to the low band crowd on the reflector. You are listening on 160 or 80 meters in the winter. You are having trouble with some kind of noise interference. Your antenna on receive is unity gain or less, but you have a 30 to 40 dB receiving preamp on your receiving antenna. You are running the noise blanker in the IF mode on the K-3. Is it not possible that you are having the same issue as I discovered? The interfering signal is off frequency somewhere relatively close by and the IF noise blanker is somehow opening up the receiver to QRM on the desired receive frequency? Based upon what I discovered today, there is certainly a issue with the IF noise blanker in the K-3 (don?t know about the other Elecraft radios) where lots of gain is used to amplify weak received signals and where there is (are) very strong (maybe just dirty FM signals) close by. My situation could be easily duplicated. I now recall that I first noticed this very same problem about 8 years ago with the same K-3 on 2 meters. This was at another QTH with a normal suburban lot and the same antenna. I was receiving a loud interfering signal on 144.2 mHz that I tracked down as cable channel 16 (I think) at about 136 mHz or so. This was also an FM video and audio signal and I am sure that I tried unsuccessfully to eliminate the interference using the K-3?s IF noise blanker. I had the Comcast tech come out and he explained that Comcast disconnected service to a neighbor about 100 feet away. When he said ?disconnect? that is what he meant, leaving an exposed center conductor on their coax to radiate. They do not put a short or load on the disconnected line so it just radiates. Nice! The good news is that the digital noise blanker worked well with my issue. Again, thanks for all the very helpful input! 73?s Dick W5AK On Jul 27, 2018, at 8:59 PM, Richard Beerman wrote: > > Wonder if anyone else has encountered this on 2 Meters?

I can tell you that connecting the same antenna/transverter to a Kenwood TS 590SG, there were no traces of the APRS signals. And connecting the TS-790S to the K1FO likewise produced no APRS QRM at 144.150. To me, with the presence of a number of strong APRS signals on 144.390 makes this K-3 extremely unusable on 2 Meters. I was running the K-3 noise blanker to handle the rest of the noise here but likewise, I also had noise blankers running on the two Kenwood radios as well. > > Any suggestions are welcome.

Do NOT break the body of the MMIC, you will destroy it. Find the one lead that is cut at an angle (that is the input) and orient it toward the center of the board. If you cannot see the angled end, it is the lead closest to the dot on the body. If there is a hole in the board, the body of the MMIC goes into that hole. If there is no hole, orient the MMIC so the angled lead (or dot) is toward the center of the board. Solder those "ARMS" to the 4 solder pads below. If there is no hole for the body you have to press the leads down with a screwdriver to make contact with the solder pads, then do it. No wires are necessary - just fill the holes on the solder pads with solder and solder the leads flat onto the board. 73, Don W3FPR On 7/28/2018 8:26 PM, Scott wrote: > Arrgh.? Where to begin.?

Elecraft can and should do better. Yes, we used two IC-7851s at WRTC and the scope worked as you described. Besides you could use a right-click on the mouse to listen on a frequency and return to your CQ-frequency upon releasing the button. Yes, the fine-tune functionality is missing at ICOM. During practical operation one hand was controlling the mouse and the other hand the main-VFO for fine-tuning. Room for improvements! > If Elecraft needs to ?monetize" this to make it happen, *I would gladly pay > $50 for a P3 firmware upgrade that provides P3SVGA mouse support.* I would be willing to pay for it as well. While playing with my P3 with SVGA-option for a while, now, I realize that I sometimes would prefer a slightly faster waterfall speed. On the other hand I never use the scope display above the waterfall. So maybe some CPU power could be rearranged to optimize the waterfall. Thanks everybody for a good P3 discussion! 73, Stefan DL1IAO, SA3CWW/SM9A -- Stefan v.

Now, as I understand the P3 cannot handle more than one USB device and if Elecraft ever adds mouse support to the P3 the Genovation keypad cannot be used at the same time. Has someone succeeded to connect the Genovation or another keypad directly to the K3/K3S instead of the K-Pod? If not, is there a chance this functionality can be added? Maybe something like a A/B USB-switch to choose between a mouse or keypad in junction with the P3 could be a solution. 73, Stefan DL1IAO, SA3CWW/SM9A -- Stefan v.

I found out what I did wrong. or did not do right.....wait. here is the procedure in the users guide:Setting the Date and Time Turn the K2 on. Tap M E N U , then tap D I S P L A Y to switch to the secondary menu, and locate the R T C menu entry. E D I T the parameter and change it to O N using B A N D + or B A N D - . (This enables the clock feature.) Tap M E N U twice to return to the frequency display. To set the real-time clock you must set the date first, then the time, as described below. (The KAF2 firmware enforces this sequence to help prevent accidental time changes. If you attempt to set the time first, or if you switch between time and date display more than once, any changes will be disabled.) 1. Turn the K2 off, wait a few seconds, then turn it back on. If you plan to use WWV or some other on- air time announcement, tune it in now. If you're setting the clock to UTC, don't forget to use the UTC date if it's different from the local date. 2.Tap D I S P L A Y . After about 1 second, you should see a time display (H H . M M . S S ). The time may not be changing at this point, and may be set to 0 1 . 0 1 . 0 1 or to a random time. Note: The receiver is not muted when time is displayed, so you may hear microcontroller-generated noise. If the noise is objectionable, turn down the AF gain when leaving the clock displayed for long periods of time. 3. Hold B A N D +and B A N D -together to switch to date display (M M - D D - Y Y or D D - M M - Y Y3). 4.Tapping B A N D + or B A N D - will now change the day, and holding B A N D + or B A N D -will change the month. To change the year: If the month is set to 1 2, each subsequent hold of B A N D +will increment the year. If the month is set to 1 , each subsequent hold of B A N D -? decrements the year. Once the desired year is selected, you can set the month by moving it back in the other direction. 5. With the date now set, hold B A N D? and B A N D - together to switch back to time display. 6.Tapping B A N D + or B A N D? will now change the minute, and holding B A N D + or? B A N D? will change the hour. Every change resets seconds to 0 0, so you can sync to a time reference if desired. 7. To disable further changes, switch to date display, then back to time display. Then move the VFO knob or tap? D I S P L A Y twice to return to the normal frequency *Here is what i found* Tap BAND+ or BAND- to set Day ( there is about a 1-2 sec delay between tap and change!) change the day, even if you put it back before trying to set time Hold BAND+or BAND- to set month (1-2 sec delay after depression) to set year, if year must increase,set month to 12 then, Hold BAND+ to bump year up. If year must decrease, setmonth to 1 then Hold BAND- to decrease year \once date is set Hold BAND+ andBAND- to display time. Tap BAND+ or BAND- to set minute (1-2 sec delay after tap) Press and) Hold BAND+or BAND- to set hour (1-2 sec delay after tap)when you change either minute or hour the seconds reset to zero so wait for your reference to hit 58 or 59 seconds before you make the last change. Now tap DISPLAY twice to return to frequency display and your date and time are set! What messed me up was the delay after the tap or tap and hold.

Yes, setting the time on the KAT2 is made intentionally difficult by the firmware.

For the record I read the manual pdf several times and had figured out the orientation of the MAR-1, it's just the soldering instructions that did not compute, "solder to the pads below"... the pads below did not look like pads but mere silk screen. After I saw a picture of it soldered (thanks Chuck), I reexamined the PCB. What looked like silk screen for the MAR-1 the 20+ times that I looked at the PCB before now looked like metal pads. The minimal difference in the color of the silkscreen and the metal pad was my confusion. I guess my color vision is starting to go. At any rate, it is now clear how to solder it to the board. Thanks again to everyone. Now to solder it and get the spare back to Elecraft. Scott AD5HS On 7/28/2018 11:03 PM, Don Wilhelm wrote: > Scott, > > Those 4 "ARMS" of the MMIC are the leads.?

Elecraft support sent me a paper on hum reduction, a longer transformer bolt, and additional rubber washers. I did not use any of this new hardware but now have acceptable hum/buzz during TX. I learned that hum/buzz is strongly related to PA current. I first made a significant reduction in hum/buzz by changing the transformer tap from yellow to red. This gave a high voltage below warning level at my highest line voltage. A second significant decrease in hum/buzz was achieved by matching all antenna loads to better than 1.2:1 SWR. Although the KPA500 is specified to accept loads of 1.5:1 SWR, the PA efficiency is degraded and PA currents increase as the match become worse. For bands where I use my KAT500 tuner I have manually selected L and C to gives a match better than 1.05:1. Bottom line - if you don't like the KPA500 hum/buzz level consider changing the transformer tap and improving load matching. Neither of these factors is mentioned in "KPA500 Application Note - Hum Mitigation.pdf". I went from a hum/buzz level greater than fan speed 4 to less than fan speed 1. 73, Andy k3wyc From k6dgw at foothill.net Sun Jul 29 20:10:25 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 29 Jul 2018 17:10:25 -0700 Subject: [Elecraft] Lightweight and inexpensive remote control of my K3s In-Reply-To: <00a201d4278c$65794ca0$306be5e0$@net> References: <00a201d4278c$65794ca0$306be5e0$@net> Message-ID: <1a9e7beb-d1cd-45e9-6978-33d67c829cf9@foothill.net> There are two flavors of K3/0's.?

Remember, this plugs into the P3/SVGA, not the K3 as you originally asked. The only difference I see today, is the current version is version 2.0, while I used version 1.1. I suspect this is just a software change, which will make no matter if so. I have the keypad image to update the keypad which makes it P3 compatible on my site as well. You will need to have the P3/SVGA to make this work. 73s and thanks, Dave (NK7Z/NNR0DC) https://www.nk7z.net ARRL Technical Specialist On 07/29/2018 02:54 PM, hawley, charles j jr wrote: > So I've been looking at the these keyboards on the sites. > > I find the CP48 USB UHID and the CP48 USB VS and the CP48 DB9S > So the one I want is the CP48 UHID one? > Just to be sure... > > Thanks, > Chuck > c-hawley at illinois.edu > Amateur Radio, KE9UW > ________________________________________ > From: elecraft-bounces at mailman.qth.net [elecraft-bounces at mailman.qth.net] on behalf of Dave Cole (NK7Z) [dave at nk7z.net] > Sent: Sunday, July 29, 2018 10:23 AM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] Genovation keypad & K3/K3S > > Here is a complete how to, with software, and macro list: > > https://www.nk7z.net/adding-external-keypad-k3/ > > I will be interested to see if a hub can be implemented. > > 73s and thanks, > Dave (NK7Z/NNR0DC) > https://www.nk7z.net > ARRL Technical Specialist > > On 07/29/2018 07:09 AM, Stefan von Baltz, DL1IAO wrote: >> Taking the P3 discussion one step further: >> Based on the positive experience of other K3/K3S users I have ordered a Genovation CP24 keypad to implement band buttons and change AGC settings on the fly.

Speaker wire is made for speaker systems. Although it may look like "lamp cord" it is not listed for use to wire up a lamp. You should buy rated "lamp cord" for that purpose. I think the same applies for dc wiring. I am not the code inspector for anyone, so do what you want, but if I had a long remote power supply feed, it would be wired with the proper size cable rated for the purpose. I suppose one idea could be to splice the larger size cable required for the longer distance to the Elecraft supplied cable at the termination end of the amplifier. The power supply protection protects the smaller Elecraft wire as designed, so going back to it at the very end is not an issue. -- Sent from: http://elecraft.365791.n2.nabble.com/ From marklgoldberg at gmail.com Mon Jul 30 10:07:39 2018 From: marklgoldberg at gmail.com (Mark Goldberg) Date: Mon, 30 Jul 2018 07:07:39 -0700 Subject: [Elecraft] Decoding the Serial Output from a KX3 In-Reply-To: References: Message-ID: I have asked if this will work, but did not get any answers.

The S-BOX enables easy connections between the KX2/KX3 ACC ports and standard D-SUB connectors used for serial ports (9 pins) and the KPA500 AUX port (15 pins). No custom cables or soldering required. As long as a PC is polling the KX3, other devices such as the KPA500 and perhaps your screwdriver controller can "listen in" on this serial traffic and change bands automatically, like the SteppIR control box does. All the "Y" connections are handled in the S-BOX. No Arduino needed unless required by your Screwdriver controller for some reason. I don't have connection diagrams for the KX3 up on the web site yet, but I'm working on an update. Of course the S-BOX can do the same thing for a TS-590 just as well, plus it will allow computer-generated CW keying over the same serial port (DTR pin), something the K3 has built-in, but the TS-590 and KX3 do not. 73, Bob, N6TV https://bit.ly/S-BOX https://bit.ly/Y-BOX On Mon, Jul 30, 2018 at 11:05 AM, Brian Waterworth < brian.waterworth at gmail.com> wrote: > It does.

It may work, but in the KX3 documentation, the ACC2 PIN GPIO as AUXBUS is only documented for communication with Elecraft's transverters, not the KPA500. Trying to drive the screwdriver controller with AUXBUS data will require reverse engineering the AUXBUS protocol, which is not recommended (not published, subject to change). My main point is that the KPA500 can automatically follow the KX3's frequency without having to use the AUXBUS. You just set RADIO to SERIAL, RS 232 X to the KX3 baud rate, and connect the KPA500's RS232 XCVR port (the MALE DE-9 connector, rarely used) to the KX3. The S-BOX can do that for you using a standard serial cable plugged into the back and an RCA stereo cable plugged into the front, plus it can share the KX3 frequency with other serial devices and KEY CW.). 73, Bob, N6TV On Mon, Jul 30, 2018 at 11:29 AM, Mark Goldberg wrote: > I was trying to find out if the Auxbus works between the KX3 and KPA500. > That would be ACC2 IO = TRN CTRL and connect ACC2 tip to the KPA500 Auxbus. > The ACC2 Ring is already connected to the KPA500 PTT in and works fine. > > There is no PC in the picture.

Although it may look like "lamp cord" it is not listed for use to wire up a lamp. Right -- it has to do with voltage breakdown of the insulation, which must be 3kV on the AC power line (in the case of a lightning spike). It is my understanding that the KPA1500 operates at about 60VDC, and that cable is carrying 50-60A. There are no lightning spikes to contend with. All that matters is DC resistance, sufficiently robust physical construction, and voltage breakdown. In large sound systems, power amps often produce voltage peaks in the range of 150V. FWIW, the Red/White zip cord sold as speaker cable is often pretty lousy quality. Insulation is made very thick as a marketing measure -- to make it look "beefier" than it really is, and therefore worth more money. :) When I've measured some hamfest cables like this with a micrometer I've found that they're actually smaller than labeled!? In other words, we're getting cheated. :) 73, Jim K9YC From davidjw1 at cinci.rr.com Mon Jul 30 15:36:51 2018 From: davidjw1 at cinci.rr.com (David J "Dave" Windisch) Date: Mon, 30 Jul 2018 15:36:51 -0400 Subject: [Elecraft] test for blocking Message-ID: <004901d4283c$abd9e640$038db2c0$@cinci.rr.com> test for blocking From gd0oud at manx.net Mon Jul 30 15:47:28 2018 From: gd0oud at manx.net (Stuart Hill) Date: Mon, 30 Jul 2018 20:47:28 +0100 Subject: [Elecraft] FW: Enquiry Time Message-ID: <002801d4283e$25cca900$7165fb00$@manx.net> Does anyone know the usual time taken to get a reply from the k3support at elecraft.com email address?

Trying to send it Auxbus traffic thus would be fruitless. Bob?s comment about connecting the KX3 and KPA500 using the serial connection is a very good one. In fact when I was developing the KPA500's communications code, I used a K3 for testing. As he alludes, sharing this data from the KX3 with the KAT500 should provide the information you need. You can do this with one of his S-Boxes, or a simple Y cable should do the trick, with the transmit data coming from the KAT500 disconnected so that only one device drives the line. The KPA500 can then poll as required, or you can have the KX3 auto-send data as Bob describes. The KPA500 responds to IF; FA: and FB; messages - it polls for all three when RADIO = SERIAL and SER POLL = ON. Thus the FA; response going back to the KAT500 should be just what you want. If the screwdriver controller also understands FA response (or FB; or IF; for that matter) then you should be in good shape. The proposal to use a small computer (Raspberry PI, etc) will certainly work, it just needs a little careful coding. I would stay away from the Auxbus stuff, though.

If sent over the weekend or late Friday or on a Monday, realize that Mondays are very busy with support emails trying to catch up with the weekend backup. I suspect something has happened to the email in cyberspace. I suggest re-sending. You may use support at elecraft.com since the other support addresses all flow into the same bucket anyway (or at least they should). 73, Don W3FPR On 7/30/2018 3:47 PM, Stuart Hill wrote: > > > Does anyone know the usual time taken to get a reply from the > k3support at elecraft.com email address?

There is no automated screwdriver controller. I would make one that drives the motor and sends serial commands to the KPA500 to go to standby, to the KX3 to go into tune mode and respond back with the SWR and then I would adjust the screwdriver antenna and re-enable the amp. All the controllers I know of have a separate directional coupler, something extra to put in the line, and don't account for putting the amp in standby for tuning. Basically looking to fully automate with what is already included in the Elecraft equipment, under software control. I have build several special purpose Arduino projects to do similar things. There is no tuner except the screwdriver antenna. Yes, I know I can buy things to hook together to do what I want, but I am now retired, with lots of time, a brain to keep occupied and not as much money! 73, Mark W7MLG On Mon, Jul 30, 2018 at 1:03 PM, Jack Brindle wrote: > Just a quick reminder (for Bob), the KPA500 does not listen to Auxbus > traffic at all.

Have your controller break the PTT line for this (with a small relay) so that the KPA immediately stops amplifying. Since you want your controller to issue commands to the KX3, you can use a regular Y cable at the KPA500, but be sure that SER POLL = OFF. The KPA has an internal relay that will disconnect its RS-232 drive on the XCVR port for this situation. I think you will find that having the directional coupler will provide a far better solution. The KX3 will tell you the match going into the KPA500, but not necessarily the one the KPA500 sees. The KPA500 _will_ modify the load the KX3 sees making the SWR info somewhat useless. The FWD and REF power (or SWR) measured by the KPA500 at low power may not give you enough resolution for your needs. Making a directional coupler is rather easy, and the code for handling the data is not too bad either. The thing to watch for is to measure the two values (FWD, REF) as close to each other in time as possible. Sampling them simultaneously is ideal. Sounds like a fun project. Good luck with it! 73, Jack, W6FB > On Jul 30, 2018, at 1:14 PM, Mark Goldberg wrote: > > Thanks. > > There is no automated screwdriver controller.

Although it may look like "lamp cord" it is not listed for use to wire up a lamp. Right -- it has to do with voltage breakdown of the insulation, which must be 3kV on the AC power line (in the case of a lightning spike). It is my understanding that the KPA1500 operates at about 60VDC, and that cable is carrying 50-60A. There are no lightning spikes to contend with. All that matters is DC resistance, sufficiently robust physical construction, and voltage breakdown. In large sound systems, power amps often produce voltage peaks in the range of 150V. FWIW, the Red/White zip cord sold as speaker cable is often pretty lousy quality. Insulation is made very thick as a marketing measure -- to make it look "beefier" than it really is, and therefore worth more money. :) When I've measured some hamfest cables like this with a micrometer I've found that they're actually smaller than labeled! In other words, we're getting cheated. :) 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 pincon at erols.com From indians at xsmail.com Mon Jul 30 18:11:42 2018 From: indians at xsmail.com (Petr, OK1RP/M0SIS) Date: Mon, 30 Jul 2018 15:11:42 -0700 (MST) Subject: [Elecraft] [WTB] KAT1 for K1 is needed...

The whip was attached directly to the back of my Patagonia Atom 8L sling bag, which turns out to have rugged, stretchy loops in exactly the right places, holding the antenna perfectly upright with no additional mounting hardware. The antenna is exactly the right length for this when the telescoping part and base are secured together. For control purposes, I just held the rig in my hand, with nothing but a coax cable running back to the pack. The rig weighs only one pound with batteries, so this turns out to work much better than putting the rig in the pack and trying to control everything with fancy firmware (something I reported on earlier). Later I operated a bit of /PM SSB, using the rig?s built-in mic and XMIT switch as PTT. The KX2 fits easily in one hand, so you might think of it as a mic on steroids, one that happens to have and all-band/all-mode radio built in :) I think I?ve finally found the magic elixir -- pure HF Pack Light. The sling pack gives this lash-up a bit of Errol Flynn cache. As for operating, this was no walk in the park! During one memorable QSO I was sending fast CW with the built-in keyer paddle while climbing a narrow 45-degree trail, praying my shoes had enough tread to grip the loose soil. The operator at the other end put up with a bit of dodgy sending as the trail?s slope hit a local maxima. Arriving at the top of the bluff, I found myself in a maze of imposing weeds sculpted by some evil California parks department employee. The plants were Vulcan in appearance, 7 to 8 feet tall, and simply irresistible to the local oversize bees. Dozens of them. I was ducking left and right to avoid the real bees while finishing my QSO with the contest ?bee." About halfway through the maze, tuning the VFO knob with the thumb of my rig-holding hand, I found another /BB station to call. I?m guessing I now hold the all-San-Mateo-County record for in-maze pedestrian mobile CW contacts. Overall, the experience was somewhere between Little Shop of Horrors and The Shining. But I didn?t get sunburned, stung, or ejected for public nerdiness. It doesn?t get much better than this.

My experience and requirement was fairly simple and I needed something brainless to help make field day easy. I have the acc2 cable from elecraft and then used a single phono cable to transmit the ptt event from the kx3 acc2 cable to the kpa500 PA Key input. Band switching was accomplished by the kpa500 directly. I quote from the kpa500 manual: *Automatic Band Switching: The KPA500 automatically measures the frequency of the RF drive * *and selects the proper band. The PA KEY input must be connected to the driving transmitter. * Again my apologies for taking us off topic as I don?t think I answered the spirit of Mark?s original post as I rely on the kpa500 to figure out what band I was transmitting via the Kx3 via the rf interconnect.

Generally, we coexist, but a couple of years ago on a Sunday afternoon I was clearing some algae and one of the little SOBs stung me on the palm.? I didn't think too much of it until my hand swelled up to double size and I developed a rash in some very sensitive areas. I didn't want to go to an ER but I did find a Walgreens with a nurse practitioner. She gave me a steroid injection and a prescription for EpiPens.? These cost Medicare about $600, thanks taxpayers. A few months ago I had a repeat, but got the stinger removed very quickly.?

It also illustrates how the S-BOX supports logger-generated CW keying over the DTR pin of the same serial port that is controlling the KX3 (something built-in to the K3 serial port, but not the KX3 or KX2). https://bit.ly/S-BOX Scroll down a bit and click on S-BOX Features and Wiring Examples then click *KX3 Docking Station*. For those using RemoteHams software with the K3 or K3S, there's a new diagram showing how one of my customers plans to use his new S-BOX to remotely power up and use his K3 with the RCForb client/server software (no RemoteRig box required). It's a complex setup with a P3, FSK keying, a KPA1500 and a Hamation ShackMaster SM-8 antenna controller all working cooperatively through the S-BOX, while being controlled remotely. I've also added new examples showing how to connect the K3/K3S (or any supported radio) to an ACOM or SPE amplifier with automatic band changes. I plan to add one more showing how to connect any supported non-Elecraft radio to a KPA1500 through the S-BOX. If you have a particular configuration where it is not obvious from the current examples and schematics how you would connect things, please send me your requirements (off line), and I'll see what I can come up with. I've also simplified the S-BOX order form a bit. 73, Bob, N6TV From K8ZCT at ARRL.NET Tue Jul 31 08:13:56 2018 From: K8ZCT at ARRL.NET (K8ZCT) Date: Tue, 31 Jul 2018 05:13:56 -0700 (MST) Subject: [Elecraft] KPA-1500 Power Supply Cable Size In-Reply-To: <1cb9a88c-30cf-037b-6c92-276696241305@audiosystemsgroup.com> References: <6aa0db70-f377-45c5-a892-ba0cdf37012f@rthorne.net> <1532949141797-0.post@n2.nabble.com> <1532958234190-0.post@n2.nabble.com> <1cb9a88c-30cf-037b-6c92-276696241305@audiosystemsgroup.com> Message-ID: <1533039236120-0.post@n2.nabble.com> Jim Brown is on the National Electrical Code Committee, so he knows what he is saying and I would trust his opinion 100%! I guess my thought on any remote wiring is, if your really going to go through all the effort to do the project, then do it with materials, that you know when you purchase them are going to work for the duration of the installation, and provide you a reliable and safe installation. Cost should not be your only consideration. I have never seen any detailed specifications on speaker wire, when I have bought it to wire up my audio system. However, I knew that I was using it to wire up speakers, and the speakers were not a long distance from the amplifier. If the remote run is long, voltage drop in the cable is very critical. You also should consider protecting the wiring, so you may need to think of using conduit or some type of protected raceway as having wires carrying 60V in the open is also not a good idea. I think that considering diesel locomotive wire or similar flexible cable would be a good solution. It all depends on how far away the remote supply is located from the main amplifier and where it is being routed to the final destination. Unfortunately, I have seen people try to use speaker wire or lamp cord to do provide power in crazy ways. One guy I remember years ago was a recent immigrant from Eastern Europe with no electrical knowledge although he was an engineer. He wired his entire basement with speaker wire. Of course, I politely told him that was not a good idea, and that it was against the local and National Electrical Code to install. His initial response was that he thought is was a lot easier to install than the solid wire cable called Romex.

It's the extra understanding of how things work, you get when doing projects like that.?? Most important for the times when suddenly things stop working, one has then the knowledge and skill to diagnose, debug and repair. A refreshing change to the "I use this device from that company" one so often sees these days. Plus, the Elecraft rigs using a Kenwood like protocol, it'd be easy to massage the code to accommodate other Kenwood like rigs, etc too. Well done.?? This is what Amateur Radio is all about.?

A legal limit amp dissipates ~1kW of heat. Small compact amps must provide the same heat dissipation as physically large amps. Thus airflow must increase in order to cool the components in a physically small case amp. Physically large amps have more room and slower airflow with the same cooling capacity. Slower air makes for less turbulence and equally less noise.

I should have stated that you are are a contributor to the 2018 Edition of "The ARRL Handbook". I have many of your articles and to be honest the ARRL "Grounding Book" has a lot of information that is also in the National Electrical Code and IEEE "Green Book". I also made major contributions to N0AX's ARRL Gounding Book -- much of it is based on the Power and Grounding slide show talk that's on my website.?

I have a little water feature in the back yard, that unfortunately has goldfish in it. My late wife's idea, so I don't want to kill them. Hence I get a lot of algae because I can't chemically treat it. I also get a lot of bees that come in for the water. Generally, we coexist, but a couple of years ago on a Sunday afternoon I was clearing some algae and one of the little SOBs stung me on the palm. I didn't think too much of it until my hand swelled up to double size and I developed a rash in some very sensitive areas. I didn't want to go to an ER but I did find a Walgreens with a nurse practitioner. She gave me a steroid injection and a prescription for EpiPens. These cost Medicare about $600, thanks taxpayers. A few months ago I had a repeat, but got the stinger removed very quickly. This time I couldn't find handy medical attention so I sat around EpiPens at the ready, but I never had a serious reaction. Still I shudder to contemplate being stung hundreds of times.
