After following a setup guide I worked and logged about 50 QSOs quite well. Then the receive signal disappears on the waterfall or meter reading in the software. The tx also disappears the radio goes into tx mode but no ALC or RF power. I am probably missing something simple but have spent days trying to figure it out without success.

I built 3 just for the pure pleasure of participating in the engineering art that the K2 represents. The key to success is to not watch the clock; to not consider time at all when performing the assembly steps. As in many things in life, you should focus solely on the current step and current component. Do not think of the next step or steps later on, or even finishing. Place each component with all the care you can. One mistake resulting from rushing will cause you frustration and disappointment. The greatest sense of satisfaction you can experience when your are finished is to know that you did everything to highest degree of perfection you are capable of.

When I went to do the 1mW calibration at the end, the calibration failed because the SWR was 2.9:1 on 52 MHz. I tried a couple more times, with different dummy loads and cables and found the same result. I then connected an external SWR meter to the dummy load and found that the external SWR meter showed a flat 1:1 SWR with the dummy load (as expected) but the K3 SWR value was always higher, typically 1.4 or 1.5:1 up to 2.9:1 on 52 MHz into the dummy load. The tuner works perfectly on all bands, however. Has anyone had a similar issue? I can?t quite tell if the problem is in the KAT3 or on the K3 main board, and more importantly what the fix might be. Also, since the 1mW calibration failed, are there any other workarounds?

They are sending me a new bottom cover and a noise kit for some transformer noise that I had not previously mentioned here. While this will involve me tearing down the amplifier and then rebuilding it the outcome will be a properly constructed amplifier. In all fairness they did offer to repair it at Elecraft but I declined because of shipping and insurance cost and not having appropriate packing since it was a kit. It was a good response I think.?

I built 3 just for the pure pleasure of participating in the engineering art that the K2 represents. The key to success is to not watch the clock; to not consider time at all when performing the assembly steps. As in many things in life, you should focus solely on the current step and current component. Do not think of the next step or steps later on, or even finishing. Place each component with all the care you can. One mistake resulting from rushing will cause you frustration and disappointment. The greatest sense of satisfaction you can experience when your are finished is to know that you did everything to highest degree of perfection you are capable of.

When I went to do the 1mW calibration at the end, the calibration failed because the SWR was 2.9:1 on 52 MHz. I tried a couple more times, with different dummy loads and cables and found the same result. I then connected an external SWR meter to the dummy load and found that the external SWR meter showed a flat 1:1 SWR with the dummy load (as expected) but the K3 SWR value was always higher, typically 1.4 or 1.5:1 up to 2.9:1 on 52 MHz into the dummy load. The tuner works perfectly on all bands, however. Has anyone had a similar issue? I can?t quite tell if the problem is in the KAT3 or on the K3 main board, and more importantly what the fix might be. Also, since the 1mW calibration failed, are there any other workarounds?

A K3 or K3S will drive one or two of them easily. The K3/K3S also have RX EQ to tailor the response to your operating position. I'll let others comment subjectively on the sound. 73, Wayne N6KR > On Feb 4, 2018, at 12:36 PM, Bill wrote: > > I am considering some station simplification, hence the SP-3.

That is for the KX3 - the PC connects to the KXPA100, the KX2 is similar. You will need the KX2ACBL to use the KXPA100 with the KX2. That is in addition to the cable that comes with the KXPA100. Those cables have nothing to do with the audio in and out for soundcard data modes, but will convey frequency and other data between the KX2 and the soundcard data software. You will have to connect the soundcard audio output to the microphone jack on the KX2 and the soundcard audio input to the PHONES jack on the KX2. Win4K3 has a great many features that you may want to take advantage of - study the WIN4K3 webpage to determine if it will enhance your particular operation. 73, Don W3FPR On 2/4/2018 5:38 PM, Tim N9PUZ wrote: > I have a KX2 and KXP100 which I would like to also connect to a computer > for sound card modes, etc. if possible.

That is especially true if the box is ported as opposed to sealed because the tuning of the port/vent is critical and will have a significant effect on the ultimate frequency response and 'Q' of the system, particularly in the lowest octave. No doubt all of that critical system design work has already been done and optimized on the SP3! ;-) 73, Dale - WA8SRA On Sun, Feb 4, 2018 at 7:36 PM, Bill wrote: > I shop at Amazon on a very regular basis.

The narrowest filters (50 and 100 Hz) do not support the equalizer, so the boost disappears (this is slightly oversimplified, since there is an option for the type of DSP filter used for the narrow bandwidths that also affects this). Anyway, the trick is not to boost any frequency ranges ? just have the equalizer cut the ones you don?t want. The rx equalizer doesn?t do much on CW with narrow bandwidths anyway, since the bandwidth determines the range of pitches that you hear.

One-owner PR-6, 6 meter-only preamp, at 0.5 dB, actually lower NF than my new one . This comes with original docs, both interface cables (one to +12 V, one to AUX) with connectors, both double-male BNC connectors to support and provide RF interface to K3. It can work fine with other receivers, just promise you won't transmit through it. Looks and works like new. Current price $160, my price $80 + $10 for regular shipping to CONUS only. This is not needed if you have a K3S. One-owner KXV3A Transverter interface for K3. This is needed for the PR-6 (or PR6-10) preamps, and not only for external transverters, but also for the internal 2-meter transverter. It also provides an IF output for use with a P3 panadapter or other SDR. It was working fine when I removed it last week, and includes original documentation and all needed hardware and cable. The K3S comes with the KXV3B, so does not need this. I will sell this for $80, 40% of the cost of the new KXV3B, plus $10 shipping to CONUS only. If you want both, I will pay shipping. I don't do paypal, so either postal money order or personal check drawn on US bank -- shipping upon clearance. Or better yet, bring cash to my house, by arrangement!

You can replace it yourself if you have de-soldering capability. If not, your K3 will have to go back to Elecraft.

I think that to get good bass response in a small enclosure you have to give up efficiency - it takes a lot more power to drive the speaker. Basically it's a tradeoff between small size, good bass response and good efficiency - pick any two.

The Pyle speakers are spec'd at 90 - 20 KHz (about the same as the SP3) and are easy to drive as well. I notice no difference in response between the speakers and my headphones (typically Yamaha CM500 but occasionally smaller, ear bud or "professional" Sony headphones) *HOWEVER* I have the K3 RX EQ set to roll off (-16 dB) the 50 and 100 Hz bands with a -6 dB roll off in the 200 Hz band for SSB/AM and with -16 dB at 50 Hz and -3 dB at 200 Hz for CW. There is no issue for me with the roll off if/when I listen to AM or shortwave broadcast but I can certainly "flatten out" the response by changing the RX EQ to flat or even add a bit of low end boost if band conditions are quiet/no QRM. 73, ...

This is a good description of the tradeoffs. BUT -- there is NO useful energy in human speech below about 200 Hz, and a cone doesn't have to be very big to reproduce that with reasonable efficiency. We're not reproducing music here. Riley Hollingsworth, our hero who cleaned up ham radio in his gig at the FCC before he retired a decade or so ago, said it quite well; "if you want to transmit hi-fi, buy a radio station." 73, Jim K9YC From jackbrindle at me.com Tue Feb 6 12:06:27 2018 From: jackbrindle at me.com (Jack Brindle) Date: Tue, 06 Feb 2018 09:06:27 -0800 Subject: [Elecraft] Different SWRs on K3 and External Meter In-Reply-To: References: Message-ID: <67A16660-B8D6-47D0-BEE4-A47D460216CA@me.com> John; Where did you have the dummy load connected for the milliwatt calibration?

This is a good description of the tradeoffs. BUT -- there is NO useful energy in human speech below about 200 Hz, and a cone doesn't have to be very big to reproduce that with reasonable efficiency. We're not reproducing music here. Riley Hollingsworth, our hero who cleaned up ham radio in his gig at the FCC before he retired a decade or so ago, said it quite well; "if you want to transmit hi-fi, buy a radio station." 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 tnnyswy at yahoo.com From k2mk.mike at gmail.com Thu Feb 1 09:49:01 2018 From: k2mk.mike at gmail.com (Mike K2MK) Date: Thu, 1 Feb 2018 07:49:01 -0700 (MST) Subject: [Elecraft] Selectivity In-Reply-To: <6bc6371a-ed29-5a5b-5ef6-fd7ea74c7595@roadrunner.com> References: <6bc6371a-ed29-5a5b-5ef6-fd7ea74c7595@roadrunner.com> Message-ID: <1517496541455-0.post@n2.nabble.com> Hi Roger, Take a look at your RX equalizer settings. If I remember correctly the DSP will not apply positive DB equalizer settings at a bandwidth setting of 100Hz or 50Hz. So if for example your pitch is set to 600Hz and you have a 6db boost dialed in on your equalizer at 600Hz then when you narrow your bandwidth you will experience a drop in audio level of 6db. Again, if I remember correctly, the solution is to only apply negative db settings for your CW RX equalizer. So you might drop all frequencies except 600Hz by 6db. Then when you narrow your bandwidth you won't experience an audio level drop. 73, Mike K2MK Roger D Johnson wrote > I noticed that during the contest, that if I selected 50 or 100 Hz > selectivity, > the audio would drop way down.

A recent firmware upgrade required a 5W and 50W re-calibration. I hadn't done a calibration since the early days of the radio back in 2008. The radio has worked fine all this time. It is on almost every day. With the tuner in bypass, I failed the 50 watt calibration on 52 MHz with an SWR >2 to 1. I finally got the calibration to pass by connecting the dummy load directly to the K3 antenna connector, without the cable. The SWR was still not 1 to 1 on 6 meters, but it was low enough to pass the calibration. I chalked it up to a tuner-bypass issue on that band. But I never went back to take a closer look. I seem to have a lot of RF in the shack on 6 meters now with my center-fed zepp. Perhaps better station grounding would help in that area. 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ From bill at w2blc.net Sat Feb 3 11:36:34 2018 From: bill at w2blc.net (Bill) Date: Sat, 3 Feb 2018 11:36:34 -0500 Subject: [Elecraft] SP-3 frequency range question Message-ID: In the real world, does the SP-3 exhibit well rounded frequency response?

I was making a few Qs but the received signals were so so weak ... I made sure ATT was off, had preamp on, checked antennas, plugs, switches, etc and I had written it off that the bands were just really bad. Then I saw it ... some how I had pushed in the RX ANT button. Even though the "RX" icon was displayed on the LCD, I didn't really pay close attention for some reason. I did not have (yet) a separate receive antenna and the signals (what few I could hear) were due to bleeding over. (still logged the Z6 on a couple of bands). Once before I had a serious receiving problem on the rig I had before my K3 ... on my old trusty FT1000 ... I could hear fine on the sub RX but nothing on the main RX. This went on for almost a month. I retrieved the box to send it off for repair. Taking one last look, I saw the problem, The width control was turned all the way to the to the left on the main RX setting the band width so tight that nothing was getting through. Setting it correctly fixed that WHEW! And a story I would tell my students ... On the weekends I loved to fix myself a big batch of pancakes from my favorite mix. One morning I was out of mix. I looked in a cook book (this was before the Internet) and saw that I had all the items to make them from scratch and so I did. They tasted awful! ... went out to breakfast. I do a good job of following instructions and couldn't let rest the bad pancakes so the following weekend I decided to make them again. I lined up the ingredients, made them again and once again, BAD. OK, this time instead of estimating the quantities, I measured carefully and scrutinized each ingredient. Again terrible! So, I wrote a letter to the publisher explaining that there could be a mistake in their wonderful cook book. A couple of weeks later I received a very nice reply:??? Dear Mr. Furrey ... Thank you for your letter ... ... ... but you should not use baking soda in the place of baking powder ... Shoot, I didn't know there was a difference. I tried it again and the pancakes were just fine. The moral of this is ... buy the mix. Seriously, check your knobs and buttons. 73, Mike WA5POK From kevinr at coho.net Sun Feb 4 14:53:03 2018 From: kevinr at coho.net (kevinr) Date: Sun, 4 Feb 2018 11:53:03 -0800 Subject: [Elecraft] Fwd: Elecraft CW Net Announcement In-Reply-To: References: Message-ID: Seems this epistle did not get out. ??

When its on its like the radio is a horse with blinders on. Any nearby flailing distractions are removed from view so the horses brain doesn?t have to process it. Its not that often I need it but when some other strong signal is close enough to your frequency and shows up on your pan adaptor the front end of the KX3 is negatively influenced and it will compromise the receivers s/n ratio and ability to receive the content to want even though you can hear it. The roofing filter will save the day and you can hold your ground and not have vacate the frequency. I use it on SSB and digimodes as well. I was recently doing QRP on the beach in the bahamas and after I got all settled in on a frequency and started a few pile ups some commercial shortwave station came on the air. It must have been very close because i Message: 22 Date: Mon, 29 Jan 2018 16:20:06 -0500 (EST) From: stan levandowski To: Elecraft at mailman.qth.net Subject: [Elecraft] KX3 Roofing Filter Question Message-ID: <765520bb.1faf0.16143ca985b.Webtop.39 at optonline.net> Content-Type: text/plain; charset=UTF-8; format=flowed I am going to order another KX3 this week. Probably tomorrow.? The last one I ordered in 2012 did not have the roofing filter option and I do not THINK I missed it. I use ONLY CW and I do NOT contest.? I like to CASUALLY chase DX and I play in low stress sprints like NAQCC but mostly I just like to RAG CHEW. My antenna is an EFHW installed as a "half square" in trees at 30 feet (MyAntennas 4010). I have reviewed the Elecraft site notes, and done a fair amount of Googling and I now am more confused than ever.? It seems that the real value lies in dealing with strong signals, crowded bands and ferocious contesting conditions. My bottom line question is this:? If I DO NOT get the roofing filter option will my KX3 receiver be LESS SENSITIVE?? The Sherwood report shows a pre-amp off sensitivity of .9 uv which improves to a very impressive .09 with the preamp on.? Is this somehow related to the roofing filter? I am especially concerned because I remember doing an A/B comparison on a weak signal between my previous KX3 and my 55 year old Drake 2B and the 2B beat the crap out of the factory built KX3.? I can't help wondering if the roofing filter I didn't buy in 2012 had something to do with this. I sure could use a real simple answer:? buy it or don't buy it?? CW sensitivity is my ultimate goal because if I can't hear 'em I can't work 'em.

Normally, my KX3 ATU is in bypass, and the KXPA100's tuner is too. The KAT500 does all of the matching. But when I want to operate in QRP, do I throw the KAT500 in bypass, turn off the KXPA100 (by the menu in the KX3? by the switch on the KXPA100?) and use the internal tuner in the KX3?

(Yay! :-)? We will be updating the shipping status page with this info tonight/tomorrow. Its been a lot of hard work getting it released and rolling, but we are all excited to see KPA1500s burning in on the test racks and heading out the door! For the next several weeks the initial shipping rate will be slow as we optimize our production and test flow, and then we will ramp up deliveries each week.?? We will be contacting customers by phone or email typically 2-7 business days prior to shipment to confirm their shipping info and get their CC for final charges etc. Please be patient with us as we get this going. Until we get the production rate increased and stable it will be hard to give exact delivery estimates due to the large number of orders. Please note that KPA1500 orders were received simultaneously via the website, emails, mail, trade shows and phone calls, so order numbers will not indicate exactly where you are in the delivery queue. We also received a very large number of KPA1500 orders each day during the first several weeks, so orders with the same order date will ship spread over a large number of days.

It is a Anderson PowerPole adapter for the KX3. (I have designs for the KX2 and FT-817 also.) This adapter uses a 3D printed shell to securely attach the adapter to the KX3, keeping the length of the low gauge wire to an absolute minimum.? There are other advantages to using an adapter like this - you can see them on the website. Please note that this current design cannot be used with an after-market heat sink.? I will have another product for that shortly. Elecraft uses available space on the left side of the radio so efficiently that it is very hard creating a design that I would be happy to take into the field. jon poland, n0wl On 1/31/2018 08:49, Dave Sublette wrote: > Good morning, > > I am using the standard power cable that is supplied with the KX3.

That is in addition to a second-hand fully loaded K2/10 I picked up in last February to start figuring out all the QRP excitement. So, with continued sales I would say they are close to, or surpassed the 8000 number. More than likely easily one of the most successful transceiver kits ever produced, and likely one of the most prolific transceivers in common use around the world. -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Robert G Strickland Sent: Wednesday, January 31, 2018 2:46 AM To: Elecraft Reflector Subject: [Elecraft] How many K2's sold As the subject says, how many K2's have been sold to date? ...robert -- Robert G Strickland, PhD ABPH - KE2WY rcrgs at verizon.net.usa Syracuse, New York, USA ______________________________________________________________ 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 wa7wjr at hotmail.com From laussana at icloud.com Wed Feb 7 00:14:37 2018 From: laussana at icloud.com (Jorge Mejia P) Date: Wed, 07 Feb 2018 00:14:37 -0500 Subject: [Elecraft] K3 No. 8527, CMP/PWR-Control not responding Message-ID: <858CAE82-DA55-4909-B11A-B41AD7D9B3F7@icloud.com> Hello Arne I had the exact sam situation with one of my two K3s serial 377 something .The power control sometimes did not work or if I wanted to increase power it went backwards, same with the CW pot.

They do seem to be more prone to this sort of thing, than other "lower class" of computing devices. It's sadly all too common an issue, and no one yet I think has found the definitive answer as to why it happens, or how! Unless you suddenly find that there is no RX immediately after a successful TX, in which case I'd suspect RFI getting into the PC/Sound-card interface. Check your cables are secure, and there are no "pin-1" problems anywhere.?? Keep the "area" of any ground loops to a minimum too. Check on the JT mode forum's etc.?? But you'll need to detail the make/model of PC, sound-card (if external) Radio.? Also the OS and version used, plus exact version of the software and perhaps sound-card drivers, for anyone to even begin to tie this down. 73 Dave G0WBX ------------------------------------------------------------------------ On 06/02/18 21:12, elecraft-request at mailman.qth.net wrote: > From: "Peter Lambert" > To: "'2M0TGN'" , > Subject: Re: [Elecraft] wsjtx-x drops receive signal and stops txing > randomly > Message-ID: <011a01d39c9b$35f9bea0$a1ed3be0$@qa.com.au> > Content-Type: text/plain; charset="us-ascii" > > First thing I'd check is that the PC hasn't decided that you really meant to > be using some other audio port and "done you a favour".

A 1 M length of 18 gauge cable will drop less than 0.1 V at the maximum current of 2.5 A the KX3 can draw at 15 W. Your internal voltage reading of 11.4 V is too low for the KX3 to allow operation over 5 W, and the problem is your power supply voltage is too low. I suggest you use a power supply which delivers at least 13.8 V with a receive load of 0.2 A. That will fix your transmit power issue, and it is the reason we designed the Kx33 Low-RFI power supply to output 14.2 V at a KX3 receive load of 0.2 A. There are other advantages as well to this higher supply voltage such as higher power output with lower IMD in digital and SSB modes. Cheers & 73, Howie - WA4PSC www.proaudioeng.com >>I am using the standard power cable that is supplied with the KX3.

This problem resulted in a complete mix-up of the function assignments of almost all buttons in the front panel - so I had to repair it. I decided to exchange all 4 encoders - because the types were changed in the meantime and the push feeling is different. As already written in an other comment: It was not really fun and not so easy. And the end I was quite happy when I powered it up and everything was working again (and nothing else got broken during the repair)... You may have already the latest encoder revision - in this case it's "only" one to replace...

I do quite a bit of SOTA and travel with my KX2, and I?ve found that it does very well. It holds a power cord, USB cord, extra KX2 internal battery, paddle, microphone, and an extra antenna adapter (and the radio!). It?s kinda fat when filled up, but works like a champ. I take that case and slide it into my backpack and I?m off and running. I?m a huge Pelican case fan (my wife informed me of this ?condition?), but I still like the Lowe Pro case for the KX2 (mine also has the SideKX panels and cover that you?re talking about). If you want ideas on Pelican cases, let me know?I have a case for just the KXPA100 and a case that holds a KX3, PX3, and KXPA100?I can give you those details/pictures if you need them. -Brad Butler W6BJB/JS6TQS From: KX3 at yahoogroups.com [mailto:KX3 at yahoogroups.com] On Behalf Of Richard Thorne rthorne at rthorne.net [KX3] Sent: Wednesday, February 7, 2018 1:28 PM To: KX3 at yahoogroups.com; Elecraft Reflector Subject: [KX3] KX2 Travel Case for Portable Operation I've seen a few neat ideas on how to carry/use a KX2 in the field.

ALC is not a "compression" mode and should not be used as such.?? The ALC performance in modern transceivers will usually be superior in performance to the voltage derived in the amp and then processed by the transceiver to control drive power. The amp should have adequate safeguards designed in to prevent overdrive and alert the operator of such occurrence. 73 Bob, K4TAX K3S - sn 10163 On 2/7/2018 6:39 PM, Nr4c wrote: > Just don?t do it. > > Sent from my iPhone > ...nr4c. bill > > >> On Feb 4, 2018, at 2:18 PM, Dave Cole (NK7Z) wrote: >> >> I have asked on and off about ALC over the past few months, and I think I want to use ALC as a safeguard to amp overdriving as an error, not as a way of obtaining compression.

I believe at lower BW settings the EQ will be negated thus you are losing the effects of the applied boost.?? As an operating practice, little to no RX EQ should be used for CW mode as EQ typically creates phase effects impacting harmonic content of the audio signal.???

It?s not overly padded but rather intended to slip into your main rucksack and not dig into you like a pelican.

I just picked up a very nice KX2 (Thanks WB5XX) that I plan on using for SOTA op's. It came with the SideKX end panels and the protective plastic cover. I was on a SOTA trip with WG0AT last September and he had a very nice tin that the KX2 fit in. It wasn't much bigger than the KX2. I've also run across the nice pelican case style setups. While the pelican case will definitely protect the KX2 it seems like a bulky solution while hiking. When I activated a couple SOTA"s last summer I took my KX3 with the side panels/cover. I just wrapped it with a towel and stuck it in my back pack. While it worked I didn't think it was the best solution. What are others doing?

Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed As a general practice, most do not recommend using ALC from the amp to the transceiver.??? ALC is not a "compression" mode and should not be used as such.?? The ALC performance in modern transceivers will usually be superior in performance to the voltage derived in the amp and then processed by the transceiver to control drive power. The amp should have adequate safeguards designed in to prevent overdrive and alert the operator of such occurrence. 73 Bob, K4TAX K3S - sn 10163 On 2/7/2018 6:39 PM, Nr4c wrote: > Just don?t do it. > > Sent from my iPhone > ...nr4c. bill > > >> On Feb 4, 2018, at 2:18 PM, Dave Cole (NK7Z) wrote: >> >> I have asked on and off about ALC over the past few months, and I think I want to use ALC as a safeguard to amp overdriving as an error, not as a way of obtaining compression.

I believe at lower BW settings the EQ will be negated thus you are losing the effects of the applied boost.?? As an operating practice, little to no RX EQ should be used for CW mode as EQ typically creates phase effects impacting harmonic content of the audio signal.??? It is always much better to "attenuate" as opposed to "boost". 73 Bob, K4TAX On 2/7/2018 6:27 PM, Nr4c wrote: > ?Selectivity???? > > Do you mean DSP filter width? > > Narrow width does decrease the background noise. > > Sent from my iPhone > ...nr4c. bill > > >> On Jan 30, 2018, at 4:05 PM, Roger D Johnson wrote: >> >> I noticed that during the contest, that if I selected 50 or 100 Hz >> selectivity, the audio would drop way down.

What has surprised me is that when either tuning or operating the KPA-500 with WSJT-X there is a very noticeable buzzing noise, not a transformer hum, from the unit. The Power output LED?s light up but the last one appears to flicker at the same frequency as the buzzing.. This happens irrespective of whether the output is 50w or 300w. The KPA-500 is driven by a Flex-6700. Grateful to know if anyone else experiences this? I was expecting a very quiet unit but this buzzing is quite disconcerting.

DTMF tones work fine on the K3 as do also the UP and DOWN buttons with MIC BTN On in the CONFIG menu. The DTMF tones also work on the K2. What is surprising, however, is that everything works equally well whether MIC BIAS is On or Off. I would have thought that the voltage on pin-6 of the front panel socket would have gone off when MIC BIAS is set to Off, but that is evidently not the case.

So, it actually serves dual purpose, and is very easy to pack anywhere and while it doesn't offer the knock around protection of a Pelican case, I am not in the habit of throwing around electronic equipment. -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob DeHaney Sent: Thursday, February 8, 2018 3:58 PM To: elecraft at mailman.qth.net Subject: [Elecraft] Travel Cases Check Online for Drone backpacks and cases from DJI etc. They are very reasonably priced and have compartments for small drones, batteries, remote control, etc. Vy 73 de Bob DJ0RD/WU5T -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of elecraft-request at mailman.qth.net Sent: Thursday, February 8, 2018 09:18 To: elecraft at mailman.qth.net Subject: Elecraft Digest, Vol 166, Issue 8 Send Elecraft mailing list submissions to elecraft at mailman.qth.net To subscribe or unsubscribe via the World Wide Web, visit http://mailman.qth.net/mailman/listinfo/elecraft or, via email, send a message with subject or body 'help' to elecraft-request at mailman.qth.net You can reach the person managing the list at elecraft-owner at mailman.qth.net When replying, please edit your Subject line so it is more specific than "Re: Contents of Elecraft digest..."

It?s not overly padded but rather intended to slip into your main rucksack and not dig into you like a pelican.

I just picked up a very nice KX2 (Thanks WB5XX) that I plan on using for SOTA op's. It came with the SideKX end panels and the protective plastic cover. I was on a SOTA trip with WG0AT last September and he had a very nice tin that the KX2 fit in. It wasn't much bigger than the KX2. I've also run across the nice pelican case style setups. While the pelican case will definitely protect the KX2 it seems like a bulky solution while hiking. When I activated a couple SOTA"s last summer I took my KX3 with the side panels/cover. I just wrapped it with a towel and stuck it in my back pack. While it worked I didn't think it was the best solution. What are others doing?

Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed As a general practice, most do not recommend using ALC from the amp to the transceiver.??? ALC is not a "compression" mode and should not be used as such.?? The ALC performance in modern transceivers will usually be superior in performance to the voltage derived in the amp and then processed by the transceiver to control drive power. The amp should have adequate safeguards designed in to prevent overdrive and alert the operator of such occurrence. 73 Bob, K4TAX K3S - sn 10163 On 2/7/2018 6:39 PM, Nr4c wrote: > Just don?t do it. > > Sent from my iPhone > ...nr4c. bill > > >> On Feb 4, 2018, at 2:18 PM, Dave Cole (NK7Z) wrote: >> >> I have asked on and off about ALC over the past few months, and I think I want to use ALC as a safeguard to amp overdriving as an error, not as a way of obtaining compression.

I believe at lower BW settings the EQ will be negated thus you are losing the effects of the applied boost.?? As an operating practice, little to no RX EQ should be used for CW mode as EQ typically creates phase effects impacting harmonic content of the audio signal.??? It is always much better to "attenuate" as opposed to "boost". 73 Bob, K4TAX On 2/7/2018 6:27 PM, Nr4c wrote: > ?Selectivity???? > > Do you mean DSP filter width? > > Narrow width does decrease the background noise. > > Sent from my iPhone > ...nr4c. bill > > >> On Jan 30, 2018, at 4:05 PM, Roger D Johnson wrote: >> >> I noticed that during the contest, that if I selected 50 or 100 Hz >> selectivity, the audio would drop way down.

(The number of orders in even the first 30 minutes was amazing..) Here's a copy of what is currently posted on the shipping status page: *(Feb 6, 2018)? KPA1500s are now Shipping!* KPA1500s have now started shipping against our backlog (we started several days ago). Yay! :-) Its been a lot of hard work getting it released and rolling, but we are all excited to see KPA1500s burning in on the test racks and heading out the door! The first several weeks of production will ramp ramp up slowly, with the production rate speeding up after that. Email and/or phone notifications will be sent each week to customers whose KPA1500 will be shipped within that week. We are now beginning to ship orders from August 24th, the first day we began taking orders. Due to very large rush of orders we received that day, we expect to be shipping the Aug. 24 orders over the next 3-4 weeks. Please note that KPA1500 orders were received by the website, emails, mail, trade shows and phone calls, so order numbers will not indicate exactly where you are in the delivery queue. We also received a very large number of KPA1500 orders daily during the first several weeks, so orders with the same order date will ship spread over a large number of days. You can also see eHam reviews of the KPA1500 at: *http://www.eham.net/reviews/detail/13702* 73, Eric /elecraft.com/ ==== On 2/7/2018 7:01 PM, Jim Miller wrote: > Early notification received 9:14pm. > > Confirmation of full paid order received 9:34pm. > > No notice received yet. > > Jim ab3cv > ______________________________________________________________ > From ne2i at yahoo.com Thu Feb 8 12:47:53 2018 From: ne2i at yahoo.com (George Cortez) Date: Thu, 8 Feb 2018 17:47:53 +0000 (UTC) Subject: [Elecraft] Major Sheldon's Last Watt In-Reply-To: References: Message-ID: <115039019.492300.1518112073710@mail.yahoo.com> Wow!

In the future, hope very near, I am interested to buy also a k-pod. I read the k-pod manual and I seen that to power the k-pod directly from the data Port there is a modification to apply. My k3s is serial number 10511 so is one of those that needs the mod. I thought to do the mod this Saturday, to open the k3s only one time but I can't find a 6.8 ohm resistor in my rubbish. Is it necessary absolutely a 6.8 ohm or is possible to use other value more diffuse? Maybe a value near to 6.8 ohm or other combination? What exactly does this mod ? Any help, please ?

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. The K3S now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via the USB port, such as a read of the K3S VFO frequency. To turn 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 PTTKEY via USB but never send commands to the K3S may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S. 73 Frank W3LPL ----- Original Message ----- From: "Fred Cady" To: "Mike Flowers" , "John_N1JM" Cc: elecraft at mailman.qth.net Sent: Friday, February 9, 2018 12:40:42 AM Subject: Re: [Elecraft] Firing up K3 attached to PC via USB Go to CONFIG:PTT-KEY, tap the 1 key and set USB.SAFE.

For a non big gun station, that means a lot of S&P and pouncing on DX cluster spots. Lots of hopping between modes. I use earphones always but still find it necessary to tinker with fan speed. Keeping ambient KPA500 fan noise down and minimizing annoying fan speed changes during QSO's, requires different initial fan speed levels for different modes. To adjust fan speed from the KPA500 front panel: 1) Press Menu 2) Scroll down 5 times to FAN CTL 3) Press Edit 4) Scroll up or down to value 5) Back out (2 presses) 6) Press TEMP, PWR or whatever parameter you choose to display while operating. This got to be a pain. W6FB at Elecraft suggested using the ^FC command to make the changes over the PC connection. You could write your own program or use the firmware program to do this. I used the firmware program and programmed macros for speeds 0 - 4. The firmware program is minimized most of the time since it takes up significant screen space. It does require a dedicated USB or COM port. It is crude but does help. Any better ideas? Maybe the aux key could be pressed into service to scroll fan speed. What would really be nice is to have it automatic with the KPA500 knowing the mode your operating and what fan speed you like for that mode. I suppose some logging program could do the same. Another solution for some-- buy a KPA1500 which is supposed to be whisper quiet. 73 de Brian/K3KO From nz3o.us at gmail.com Fri Feb 9 12:12:23 2018 From: nz3o.us at gmail.com (Byron Peebles) Date: Fri, 9 Feb 2018 12:12:23 -0500 Subject: [Elecraft] P3 Macros - MEM to MEM Copy?

This release corrects an error with a missing DLL when a SDRPlay RSP1A is used and improves the RIT/XIT function. One of the useful features of Win4K3Suite is that it interfaces to all 3rd party logging and digital mode programs such as HRDLogbook, DX Keeper, NAP3, N3FJP, N1MM+, FLDigi, MIXW as well as hardware devices such as the K3/0, the Pig Knob and various antenna tuners and amps. In order to understand how to do this, there is a video on youtube that gives clear instructions on using the virtual port management facilities of Win4K3Suite: You can access it at https://www.youtube.com/watch?v=1jh6IS0S1dE&t=4s In case you are not aware, Win4K3Suite is a comprehensive control program for the Elecraft K3, K3S, KX3 and KX2. It supports all hardware such as the KPA500, KPA1500 and KAT500 even on the KX2. Win4K3Suite has built in panadapter support for the P3, LPPAN and the SDRPlay RSP. There is no configuration necessary to support all modes and filter settings for QSY's. You can read user reviews here: https://www.eham.net/reviews/detail/11214 There is a fully functional 30 day trial available at va2fsq.com 73 Tom P.S.

Ditch it completely and run one of the free Microsoft offerings and possibly Malwarebytes. You will need to run the KPA500 Utility to update its firmware, change the start-up banner and set various menu items easily. You should read the KAT500 manual along with Fred Cady's book. They give you sensible frequency segments to 'train' the KAT500, which is done in Auto mode. Once you've stored tuning parameters (automatic) for each band and antenna, you should switch to Manual mode, then every time you use a particular frequency, the KAT500 will tune to the nearest segment and settle down within milliseconds. 73, Alan.

Issues I am having: 1) KAT500 makes quite a racket whenever keying up. It seems to settle down, but as soon as I speak, it freaks out again. He has two antennas...a hex beam on ant 1 and a G5RV on ant 2. The KAT500 seems to behave the same on both. 2) He is running Norton on his PC. Norton allowed me to download the KAT500 utility, but not the KPA500 utility. It automatically deletes it. What's up with that? Thanks for any assistance. I tried to contact Elecraft support, but I guess I was too close to closing.

Once I find a signal, I narrow the filter down (400hz) by tapping the AF knob after tapping the FIL button. Opening up the filter (back to search mode) requires lots of cranking on the AF knob (back to 2.8khz) after tapping the FIL button. Wouldn?t it be nice if tapping the AF knob while in filter adjust mode would return the filter bandwidth to it?s previous setting (toggle between wide and narrow). Maybe there?s a way to quickly switch the filter BW back and forth (wide-narrow-wide) without having to crank the AF knob that I?m not aware? If not, seems like it would be an easy firmware update.

I acquired my K3 this past summer and then a P3 off of eBay shortly thereafter. I installed the SVGA adapter a couple months ago and I have a problem which sounds similar to what is described in this thread. For lack of a better description let me say this symptom happens only on 20Meters..... as I view my spectrum now from 14.250 to 14.350 the noise floor rests basically around S-2 across the entire band, revealing a few transmitted ham conversations, My center frequency on the scope is 14.300 and at this moment I see occasional noise peaks rising up to as high as S-5 in two or three instances approximately 10khz wide, and at times 20 khz or wider. These noise peaks are not consistent with any observed or detected human voice transmission. At times I can see a very broad band of noise on the waterfall which spans the entirety of the floating noise floor. The same observation occurs when I am tuned down in the CW portion of the band. I don't recall if this observation was present prior to adding the SVGA adapter, and I've not thought about opening the P3 to inspect or move any cables. I know this symptom can best be demonstrated with a photo, so if that would be beneficial, I will be happy to oblige. Just let me know who needs to see it. This is certainly a very annoying issue I wish to resolve. I'm open to any ideas or suggestions.

I installed the SVGA adapter a couple months ago and I have a problem which sounds similar to what is described in this thread. For lack of a better description let me say this symptom happens only on 20Meters..... as I view my spectrum now from 14.250 to 14.350 the noise floor rests basically around S-2 across the entire band, revealing a few transmitted ham conversations, My center frequency on the scope is 14.300 and at this moment I see occasional noise peaks rising up to as high as S-5 in two or three instances approximately 10khz wide, and at times 20 khz or wider. These noise peaks are not consistent with any observed or detected human voice transmission. At times I can see a very broad band of noise on the waterfall which spans the entirety of the floating noise floor. The same observation occurs when I am tuned down in the CW portion of the band. I don't recall if this observation was present prior to adding the SVGA adapter, and I've not thought about opening the P3 to inspect or move any cables. I know this symptom can best be demonstrated with a photo, so if that would be beneficial, I will be happy to oblige. Just let me know who needs to see it.

I waited to respond until the KPA1500 manual was published to see if there were any PF1/PF2 functions out of the box. What I'd like to see first is much less fancy than interacting with external relay-based antenna switching like you mentioned. How about initially providing a second set of ATU segment memories to allow a /manual/ external switch? The amp can't know or control which antenna is selected but it would be very handy to have a PF function key the operator could use to toggle between ATU segment set one and two, for example, when the manual antenna switch position is changed. I envision it like this: ANT1 \ Manual Switch \--: Antenna 1 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 2 (Manually select ATU logical segment set 2 with PF1 hold) ANT2 \ Manual Switch \--: Antenna 3 (Manually select ATU logical segment set 1 with PF1 tap) \--: Antenna 4 (Manually select ATU logical segment set 2 with PF1 hold) Just a manual logical segment set change in support of manual external antenna switching. Is that do-able? I imagine I'm not alone in the use of manual antenna switches and needing to accommodate more than two antennas without the ATU experiencing a high-SWR-triggered re-tune hunt each time an external switch selects a different antenna.

The screws on the left front of the RF board are in the way. I did a quick review of the assembly manual before attempting to remove it and some how I didn't notice this. It would be really cool if there was a software way to swap the controls A & B. I'm not sure in how many cases this would ever be useful, but this is certainly one case.

A full SO2R box that seamlessly integrates 2 K3S radios with all the necessary cabling fully shieldied with minimal problems interfacing with N1MM+. 2.) A band pass filter solution from 160-10 with auto switching controlled with full automation by either pressing the band switch buttons on different K3S or by clicking the Icon on N1MM+. Yeah I can dream. Right now i have the MK2R+. Nice unit but really a bit of a pain to routwall the cables necessary for the control of 2 rigs. Because of the interface problems, I am looking at the Flex 6600 as a one box solution and using the K3S as a back up rig. I have been underwelmed at the 6300 as a CW radio, but it has been some years since i sat at one and maybe the software is fixed better. Time will tell. In the end, The cost of a second K3S/P3 is the same as the FLEX. $5k either way. I am getting ready to retire and will be shopping hard for that final radio for contesting full time. Money is drawing intrest in the bank and i am just waiting for the reviews. Unfortunately the Icom 7610 is not an option, even though i do love the ICOM line, it just does not have the performance necessary for a CW radio in a high RF environment. I would not be much better off buying 2 7300s and puting them with the MK2R+. Unfortunately the selectivity and desensing is the issue. They sure do sound good on SSB but if i wanted broadcast audio i would be running Antique Modulation. Just my 2 sense.

Cleaning the contact with a small strip of paper helps for a while. I'm wondering if the contact closure current may be too low to overcome the slight surface corrosion that develops over time. When not in use I store the KXPD2 in the mesh pocket of the CS-40 case. Adjusting the contact spacing narrower allows less travel and seems to make the problem worse, widening it makes it better but doesn't eliminate the problem. 73, Brian, K0DTJ > On Feb 11, 2018, at 05:56, Tommy wrote: > > Hi folks, > > The right paddle seems to work intermittently on my KX2 paddles.

Here's what I know so far. I had previously performed the idea of turning off all items in the room except for the radio and P3, but the reported symptom remains. I then switched my antenna switch to the grounded position, and the problem goes away......... Now my suspicion is that my rfi is created from outside my house. My antenna system consists of two end fed long wires, 90% opposed to each other, and a minimal vertical out behind the house. The RFI from all antennas is approximately equal in amplitude as I select them one at a time (with the vertical slightly less but I attribute that to the relative poor receive sensitivity on that antenna. Nonetheless, the RFI on that antenna is quite noticeable. I hesitate to bother for additional thoughts at this point, at least until I can asses what possible causes external to my house might be at play, and now to pay close attention to whether or not it changes depending on the hour of the day. For example, at first notice of this problem I sensed that everything was normal until for example, the beginning of the work day. I soon discounted that thought however, when I realized it was happening late at night (as was the case up until I shut down last night around 11pm). And it affects only 20 Meters. All other bands are viewed normally. Perhaps once I can capture and submit a picture for review here, someone might be able to make a little more sense out of what I'm trying to describe.........If I can say it this way, it reminds me of a TV commercial where folks are in a Gymnasium doing a strength regimen involving holding a rope in each hand and making it serpentine by moving the arms up and down. Only that sine wave of baseline noise moves from S-2 to as high as S-7 when using my best antenna.......... I'll try to get a picture attached later this afternoon. Thanks for the help so far.

Thank you, Alan. Data for this particular measurement are very difficult to find on the web -- of course it took an ex-HP guy to do it! Times Microwave (a manufacturer of coaxial cable) says 0.01 dB per UHF connector pair (PL-259-to-SO-239) at HF; I have seen other private measurements that estimate 0.02 dB; and now this data from N1AL. I usually take the greater of these, 0.02 dB, as a worst-case number. But Alan's measurements pretty much show that the loss at HF is almost too small to measure-- even if he had performed a full two-port cal. Even so, you might be surprised to see how quickly it can add up. Beginning at the transmitter output (or receiver input) it is not uncommon to find 20 or more UHF connections in the path to the antenna. Using the 0.02 dB worst-case figure, that's at least 0.4 dB, or 9% of your power. I wouldn't worry about that but I know there are folks on here that would be bothered by that. This, of course, is not counting loss in cables, filters, lightning arrestors, power meters, bulkheads, switches, antenna tuners, baluns, amplifier through-paths, transmission lines, etc. These can add another dB or more to the total and far outweigh any loss in UHF connectors. If you want to minimize losses, UHF connectors are the last thing you should worry about. I encourage you to do an analysis to determine your system efficiency. I recently did so and discovered that I have a worst-case loss (to the feedpoint up at the antenna) of 1 dB, which is 21% of my power. Gone. Forever. Whoosh!

I have frequently thought that a QRP system which has the final amplifier at the feed point of the antenna would be very attractive. A crude way of accomplishing a feed point amp would be to take a radio like the Rockmite and place it at the feed point. If you run the Rockmite with a 9V battery, all you just need wires for the paddle and the headphones. The big problem as I see it is weight at the feed point. In theory, you could handle the whole operation with a RG-174 feed line. Run DC power on the feed line, and have the feedpoint electronics switch between transmit and receive depending on the signal level on the coax. But this is just another of the projects lined up to fill the time when I'm not operating. 73 Bill AE6JV On 2/11/18 at 11:49 AM, alorona at sbcglobal.net (Al Lorona) wrote: >I encourage you to do an analysis to determine your system >efficiency.

You didn't mention how you set up your K3 as far as antenna input to the sub receiver.? I use the BNC connector on the back of the K3.? A couple times when I found the sub receiver deaf, it was a matter of "operator error" with one of my big paws "holding" rather than tapping toe RX Antenna button.? The net affect of that is switching the input from Main to Aux.? A quick push and hold of the RX Antenna button to go back to Main does wonders to fix that issue!!!? ?Also, make sure you have the KRX3 option in the Configuration Menu set correctly (mine is set to Ant-bnc).

In other words, it affects the SWR slightly but does not actually absorb any power. If you are using any kind of antenna tuner and tuning for 1:1 SWR, mismatch "losses" have no effect. Even if you aren't doing that, the antenna is probably not a perfect 50-ohm resistive load anyway, so the connectors' mismatches are about as likely to make the SWR better as worse, depending on the phase and magnitude. But the general point is sound. Power loss is even more important for QRP than for QRO even though the number of watts of loss is less. When the other station can barely hear you, every dB counts!

Beginning at the transmitter output (or receiver input) it is not uncommon to find 20 or more UHF connections in the path to the antenna.

IMO, "mismatch loss" is a figment of the imagination of those who never get outside the lab. Transmission lines was one of my favorite EE courses, and I never heard of it until I heard it referenced in online discussions a few years ago. And the purported losses in connectors are an urban legend with almost basis in fact.

Keeping track of losses in systems is, of course, a great thing. Our FD group runs (and has won several times) FD 1A QRP Battery.

I view one should always look at the component which contributes the greatest loss in the system,? that is most often the feedline.? One should strive to improve the condition by using a line type of less loss.? {i.e. better quality feed line} and eliminate excessive feed line lengths.??? Factors influencing line? losses are; type of line, age of the line, length of line, frequency and reflected power. Manufactures produce charts and tables showing loss of a specific type of line taking into consideration of length and frequency. These numbers are for new or known good line and not likely "hamfest" bargain line. A second component which often contributes significant loss is the all famous "antenna tuner".??? Recent tests show some tuners, under some load conditions can contribute up to 25% of added loss or more.?? And while at the same time, the loss in the feedline remains the same. This brings me to the point where I view many hams obsess over SWR values.? Unless the transmitter is folding back power, as many un-necessarily do, then the use of the ATU may benefit making the transmitter happy, but at the sacrifice of added loss to the system.? To that end, there are several brands and models of radios, past and present, that do not fold back power with reasonable SWR values.? I find it not at all uncommon to operate with a 3:1 SWR without issues.? In this configuration, adding the ATU makes the SWR to the radio look better, but adds loss induced by the tuner and does not change the loss in the feed line. There is an interesting compilation of data on various match boxes i.e. ATU's? and their performance found on the following link.?? The compiled information and data is from various sources and presented in XLS format. http://www.dj0ip.de/antenna-matchboxes/matchbox-shoot-out/ 73 Bob, K4TAX On 2/11/2018 10:25 PM, Jim Brown wrote: > Thanks for this excellent post, Alan!

In general the 135 ft center fed wire with your choice of balanced line, I use the vinyl covered 450 line from The Wireman, will work quite well.??? I bring the line from the feed point of the antenna all the way to the operating position where it terminated into the 1:1 current balun.? Balanced line of this type is not near as difficult to use as many will allude.?? Just use common sense.? Be sure to use lightning protection on the line before it enters the house. Regarding baluns, keep in mind that one is not "matching the line" i.e. 450 ohms but the overall load Z.?? Hence the better choice is the 1:1 current balun and not the 4:1 as many seem to believe.??? Also, understand that the design and rating of baluns is based on a matched operating condition on both sides of the balun.? The 135 ft center fed wire with balanced feed is in most cases far from matched.? Thus the balun should be rated for much higher power than one would ever expect to run.? In my case, for legal limit power, my balun is rated at 10KW.??? I do use BALUN DESIGNS products for my applications.? Be sure you select a balun which is designed to be used with a tuner as the voltage / current ratings will be different than those for matched applications. What is a matched application for a balun?.? A good example is a folded dipole made of and fed with balanced line.? Typically the folded dipole Z is about 300 ohms regardless of line impedance. However, due to reasonable proximity to the earth, the impedance is more like 200 to 250 ohms.?? Hence a 4:1 balun is the ideal choice providing an unbalanced feed to the transmitter of about 50 ohms. Here is a good source for real world applications and performance of baluns. http://www.dj0ip.de/balun-stuff/ 73 Bob, K4TAX On 2/12/2018 9:29 AM, David Bunte wrote: > Alan - > > I am pleased with results I have gotten with units from BALUN DESIGNS. > Their 1161 & 1171 models are possible choices.

The Elecraft tuners can not be beat for what they can tune, so the only real issue is how to transition to coax from open wire/ladder line. Probably, the easiest is to use a 4:1 current balun to make the transition. I would go with one that is rated at least 3KW. Why so heavy? The answer is core heating when running with a high SWR; this is more of a design "safety" issue. And, the current balun will stay balanced better than a voltage balun when presented a high SWR. I use a variant of this here in my station, meaning the antenna is slightly different. It works great with no problems and I can use my antenna 80-10 meters. DXengineering and Balun Designs make good baluns as I'm sure there are others, but I know these work. One last thought. Make the transition as close to where your egress point is. If you have a fairly lengthy transmission line run, you will be using the lowest loss line for as far as you can go and then transition. I would use a very low loss cable from the balun to the tuner, something like LMR-400. 73, Barry K3NDM ------ Original Message ------ From: "Alan Lambert" To: elecraft at mailman.qth.net Sent: 2/12/2018 9:26:40 AM Subject: [Elecraft] Suggestions needed - antenna to tuner >I could use a little advice > >My present setup is; >KX3 > KPA100 (w/ ATU) > MFJ Balanced line tuner > ladder line fed >80m Inv 'V' > >I run this with the ATU disabled and then manually tune.

The biggest benefit is that the K3 ATU remembers the settings from band to band so the QSY is very rapid. I love watching the DX spots come rolling through on my N3FJP logging program and clicking on them to QSY to that frequency and not have to tune up again. I use it on 80 through 6 meters with an 80m doublet fed with KW ladder line (300 ohm). My recommendation is to keep the piece of coax from the balun to the rig as short as possible. This is to minimize loss since that line will most likely be highly mis-matched on most bands. There was a QST article not that long ago which detailed the losses in that situation and I was surprised at how high they were. I once had an MFJ balanced RF Ammeter and made measurements of the JMB vs. the balun and they compared favorably. DJ0IP (referenced earlier) has kindly put those measurements on his website. (This is in the FWIW category!) I have not tried to substitute the tuner balun with another type but that might be a future experiment. 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ From n5lz at comcast.net Mon Feb 12 12:31:13 2018 From: n5lz at comcast.net (Don Butler) Date: Mon, 12 Feb 2018 10:31:13 -0700 Subject: [Elecraft] Y-Adapter for K3S ACC - KPAK3AUX - KPA-1500 Message-ID: <005101d3a427$48d4ecf0$da7ec6d0$@comcast.net> I've been studying the manual while waiting for my new KPA-1500 to ship ...

I used to have an Acom 2000A alongside the KPA500. I have a switch in the shack that selects the one output from the K3 to an A/B switch for the inputs of both amps and an A/B switch on the output for both amps to a coax switch. I key the amps in parallel with diode isolation. This has worked well for a long time. I like doing it this way because while the one amp is off I can use the other amp. If I have a problem with an amp all I have to do is turn off the one amp from the screen, turn on the other amp and hit the switch. I don?t have to go to the basement to do anything. Guess I can use a Y-cable with a second KPAK3AUX with both amps in parallel instead of the Y-Box. 73, N2TK, Tony From: rawilson at gmail.com [mailto:rawilson at gmail.com] On Behalf Of Bob Wilson, N6TV Sent: Monday, February 12, 2018 3:48 PM To: N2TK, Tony ; Elecraft Reflector Subject: RE: [Elecraft] Y-Adapter for K3S ACC - KPAK3AUX - KPA-1500 If you want to connect both amplifiers to the same K3, one on Antenna Port 1, the second on Antenna Port 2, just connect a second KPAK3AUX cable between the KPA1500 and the Y-BOX.

A $10 MF 15-pin cable (not a VGA cable) will work fine because the internal wiring of the Y-BOX v2.1 matches the Elecraft custom cable wiring wiring. It also adds a feature so you can power up the KPA1500 remotely with a K3 macro (something not supported by Y-adapters with an unmodified KPAK3AUX cable).

Not necessarily bugs, but these do not seem to be optimal. If you have a K3 without the Sub Rx, turning on XIT will change the transmit frequency on whichever VFO is set to transmit: VFO A if Split is off, VFO B is split is on. The receive frequency is not affected. XIT affects VFO A only in transmit, and VFO B when in Split. Perfect. If you have Sub Rx, turning on XIT with both Sub Rx and Split active immediately changes the VFO B frequency (which is now a receive frequency). VFO B is being handled as it is with the Sub Rx, which seems (to me) not quite right. It would make more sense (I think) if XIT was only applied to VFO B during transmit when the SubRx is active and Split is on. The other oddity is the display of the cursors on the P3 when controlling RIT/XIT using macros. If you control XIT using the front panel button, the red cursor is shown and removed as XIT is on or off. If, however, you turn on XIT (with an offset other than zero) by using the XT1 macro, XIT is enabled but the cursor is not displayed. If you move the Offset control, then the cursor is displayed. Similarly, if you turn on XiT using the front panel button (enabling the red cursor), turning XIT off using XT0 will turn off XIT but the P3 will still show the cursor. Not a big deal, but less than optimal. RIT does something similar. If you turn RIT on using RT0 (with an offset other than zero), the receive frequency change is not reflected on the P3 display and the green cursor does not move unless you move the Offset control. Turning RIT off using RT0 will indeed turn off RIT but the cursor and frequency display on the P3 do not update. In addition, if you now move VFO A the frequency/cursor shown on the P3 continue to be offset by the (now disabled) RIT offset. Using the front panel RIT controls show none of these oddities. You can sort of work around the P3 problems using SWT commands, but it?s not quite the same since button presses are toggles (rather than absolute commands like RT and XT) which requires knowing the current state of the function.

It makes more sense (to me) to always use the SubRx to listen to "your place in the pileup," so you can tell if you are calling on a clear frequency or a crowded one. Also, why bother with XIT at all when you're working split? Just keep XIT off and the much bigger VFO B knob, or use a command to move VFO B rather than move XIT. It would be very distracting to see the VFO B frequency jumping back and forth in full QSK mode when operating split, with the XIT on and the XIT offset set to a non-zero value, which is what you seem to be requesting. I really prefer the way it works now. But frankly, I almost never use split. I find it much easier to put the DX in the SubRX and just move the big VFO A knob to find a calling frequency. I also adjust the BALANCE control (CONFIG:SUB AF = BALANCE) so that the DX is always louder than the pileup, and in one ear only. 73, Bob, N6TV From kl7uw at acsalaska.net Tue Feb 13 03:31:53 2018 From: kl7uw at acsalaska.net (Edward R Cole) Date: Mon, 12 Feb 2018 23:31:53 -0900 Subject: [Elecraft] UHF connectors [was: Array Solutions Lightning Arrestor] Message-ID: <201802130831.w1D8Vs44031773@mail42c28.carrierzone.com> In fact my N-connector at my in-line Bird Meter element does get warm enough at 1500w at 144-MHz to "barely" discern by touch. Since room temp (70F) is 17c the connector may be at about 25c (nothing to write home about). When I first began operation of my 2m-8877 above 1kW it did burn up a N-connector which probably had poor connection. It was an old run of RG213 which should have been replaced for running that level. I replaced the two sections of coax with a single 20-foot run of LMR-600 which dissipates 0.216 dB which at 1500w is 73w power loss). LMR-600 at 150-MHz is rated at 1.08 dB loss/100-foot. So I run the amp with 1400w indicated by power meter which implies the amp is outputing 1500w (nom.). Most of the time I run 1300w which allows for 5% calib. error in the Bird indication. In the effort to achieve best NF at 1296, I actually measured connector loss in an N-elbow. It was below my measurement resolution of 0.02 dB. How I measured loss was by reading thermal noise from a 50-ohm termination with my SDR-IQ with sw set or 0.02-dB/DIV display. I only began to see some loss when I connected N-elbow + N-relay + N/sma adapter. That measured 0.15 dB at 1296-MHz. Interestingly 0.1 dB was contributed by just the N/sma adapter. For use below 50-MHz connector loss is negligible. Cable loss is way more significant but only above 50-MHz. Of course that is for NEW cable. That 25-year old run of RG8 might be loosing 2-3 dB at 20m. Cables do not last forever! Hint: measure them to know. 73, Ed - KL7UW From: Jim Brown To: elecraft at mailman.qth.net Subject: Re: [Elecraft] UHF connectors [was: Array Solutions Lightning Arrestor] Thanks for this excellent post, Alan! IMO, "mismatch loss" is a figment of the imagination of those who never get outside the lab. Transmission lines was one of my favorite EE courses, and I never heard of it until I heard it referenced in online discussions a few years ago. And the purported losses in connectors are an urban legend with almost basis in fact. Several years ago, W8JI poetically observed that if the 1 dB loss falsely attributed to UHF connectors was true, each would be burning 35 W carrying a legal limit signal, and be starting fires! Keeping track of losses in systems is, of course, a great thing. Our FD group runs (and has won several times) FD 1A QRP Battery. Every piece of coax in our station is low loss RG8 or RG11. 73, Jim K9YC 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From jwebsterlsu at gmail.com Tue Feb 13 03:34:24 2018 From: jwebsterlsu at gmail.com (John W Webster) Date: Tue, 13 Feb 2018 00:34:24 -0800 Subject: [Elecraft] Elecraft SSB Net - Report Message-ID: <77A60237-67BE-4D1A-BC56-19ED19E53DB8@gmail.com> Please consider joining us for the weekly Elecraft SSB net on Sunday?s at 18:00z (UTC).

See if this helps the 17M issue. I personally don't like the idea of using a 4:1 balun and much prefer a 1:1 current balun.? With the 4:1, without measuring the Z on the coax side, it may be the Z presented to the tuner is very low and thus outside the range of the tuner.?? Additionally, it is most likely with almost every ATU, the greatest loss occurs when the Z is low to very low.?

All of this requires a ladder and some creative juggling of tools/laptop etc. ;) 73 Chris On Tue, Feb 13, 2018 at 9:04 AM, Bob McGraw K4TAX wrote: > Chris; > > Add or remove about 6 ft of the open wire line.

You are matching the impedance seen at the shack end of the feedline, and that can vary from very low to very high. The impedance you have to match is NOT the characteristic impedance of the feedline. The 600 ohm line simply acts as an impedance transformer. The only time you will see a 600 ohm impedance at the shack end of that feedline is when the far end is terminated by 600 ohms, and I suggest that is not true of the feedpoint impedance at the antenna. 73, Don W3FPR On 2/13/2018 8:55 AM, Chris Hallinan wrote: > I have a very similar setup.

If I understand correctly, it can present from very low to very high impedances to the tuner. I will try a 1:1 and/or adding some wire length. Also, as I mentioned in my previous post, I've been wanting to get up on the ladder and scan it with my Array Solutions antenna analyzer to see what it really presents to the tuner. That may help me understand what I need to do. 73, Chris - K1AY On Tue, Feb 13, 2018 at 9:13 AM, Don Wilhelm wrote: > Chris, > > Try a 1:1 balun instead of the 4:1.

I originally couldn't perfectly match 30 meters with the Johnson Matchbox and added about 15 or 18 feet IIRC. That brought 30m into range and didn't mess up the other bands too much. Since your worst band is 17m, you might need only a few feet (5 or 10 is a swag). 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ From john at kk9a.com Tue Feb 13 09:44:24 2018 From: john at kk9a.com (john at kk9a.com) Date: Tue, 13 Feb 2018 09:44:24 -0500 Subject: [Elecraft] KPA500 Info Disappeared From Website Message-ID: <1f09203b62cdbb858498be8bde25bfda.squirrel@www11.qth.com> The photo also vanished from the products page http://www.elecraft.com/elecraft_products_page.htm I guess it was replaced by the KPA1500 :) John KK9A From: Mark W7MLG Date: Tue Feb 13 09:00:53 EST The KPA500 links seem to have been broken on the Elecraft Website: Not Found The requested URL /KPA500/KPA500.htm was not found on this server. 73, Mark W7MLG From rich at wc3t.us Tue Feb 13 10:26:17 2018 From: rich at wc3t.us (rich hurd WC3T) Date: Tue, 13 Feb 2018 10:26:17 -0500 Subject: [Elecraft] KPA500 Info Disappeared From Website In-Reply-To: <1f09203b62cdbb858498be8bde25bfda.squirrel@www11.qth.com> References: <1f09203b62cdbb858498be8bde25bfda.squirrel@www11.qth.com> Message-ID: Hmm.

Find the line ; default-sample-rate = 44100 toward the end of the file, delete the leading semicolon and space and then change the value to 48000. It should now look like this: default-sample-rate = 48000 Save the file, then reboot the entire system to ensure Pulse Audio restarts and grabs the updated settings and see if that helps you at all.

So, for years I used a Kenwood or two, then a Yaesu or three, then a Ten-Tec. Much of the time on CW. When I tuned a band, say 20M, I would start at the bottom of the band and tune upwards in frequency. When I did this, as I approached a CW signal it would be higher-pitched. As I tuned it to zero-beat with my 500-Hz CW offset the pitch would drop until it matched my 500 Hz spot. If I tuned too far, the pitch would drop below 500, then drop off the scale as I tuned past it. Similar in fashion to tuning a USB signal. My Elecraft tunes similar to one other rig I have owned, an iCom 706 MkIIG. As I tune up the band I first hear a low-pitched CW signal, then it centers, then it gets higher in pitch. Similar to tuning an LSB signal. This doesn't make a difference in usability, I guess it's due to the receiver architecture. And, yeah, I can go to "CW-R" and it works the way all those other radios did. My question is, is there a reason for it working this way? Does it provide some advantage?

There are two ways to get 80 meters (3.5-4 MHz) and 20 meters (14-14.5 MHz) using a single VFO and IF: 9 MHz IF, 5-5.5 MHz VFO: - Sideband direction is the same on both bands - VFO tuning direction is inverted on 80, non-inverted on 20 5.25 MHz IF, 8.75-9.25 MHz VFO: - Sideband direction is inverted on 80, non-inverted on 20 - VFO tuning direction is the same on both bands So the convention about using LSB on the low bands and USB on the high bands has nothing to do with a 9 MHz IF. It may have to do with using a 5.25 MHz IF and a VFO centered on 9 MHz.

The sidebands will NOT invert with a 9 MHz IF and a 5 MHz VFO. A little simple math should convince you. Assume a 9.000 MHz IF and a 5.200 MHz VFO and a modulating frequency of 1kHz. 9.000 + 5.200 = 14.200 for the carrier frequency 9.001 + 5.200 = 14.201 for the modulated frequency. That is Upper Sideband. 9.000 - 5.200 = 3.800 for the carrier frequency 9.001 - 5.200 = 3.800 for the modulated frequency - that is also USB. The early SSB generators (Central Electronics 10A for one) did use a 9 MHz SSB generator frequency, but there was a switch to change sidebands. If you have a 5 MHz IF with a 9MHz VFO as was used by Hallicrafters, the sidebands will invert between 75 and 20 meters. Try the addition and subtraction to convince yourself. 73, Don W3FPR On 2/14/2018 3:08 PM, Ken G Kopp wrote: > Here's a URL to a website with lots of information: > > http://www.ac6v.com/73.htm#LSB > > Or, search "BC-458 command set transmitter" and > "Central Electronics 10A" with your browser. > From nz3o.us at gmail.com Wed Feb 14 16:55:46 2018 From: nz3o.us at gmail.com (Byron Peebles) Date: Wed, 14 Feb 2018 16:55:46 -0500 Subject: [Elecraft] Using DX4WIN as P3 RTTY Data Terminal Message-ID: <214955d3-e133-6064-b68e-ce9f79a8aef4@arrl.net> I am taking the plunge into DATA modes for the very first time, and I'd like to get started with a simple test: Use my existing DX logger, DX4WIN, but leverage the P3/SVGA Pan-adpater for RTTY encode and decode.?

For the first two, the P3/SVGA approach is fine. Much less so for contesting -- for that, you want MMTTY or 2Tone and a contest logger like N1MM. FWIW, FT8 has put a big dent in casual PSK and RTTY operation, and for that, you need WSJT-X and a couple of audio cables. 73, Jim K9YC From wb6rse1 at mac.com Wed Feb 14 18:15:54 2018 From: wb6rse1 at mac.com (wb6rse1 at mac.com) Date: Wed, 14 Feb 2018 15:15:54 -0800 Subject: [Elecraft] OT: USB and LSB - How we got there In-Reply-To: References: Message-ID: <2099C39B-7AFE-4878-A425-ED04B348534A@mac.com> GM3SEK, Ian White's posting here in 2008 is much more illuminating. > https://marc.info/?l=elecraft&m=121161637904298&w=2 Steve WB6RSE On Feb 14, 2018, at 12:08 PM, Ken G Kopp wrote: Here's a URL to a website with lots of information: http://www.ac6v.com/73.htm#LSB Or, search "BC-458 command set transmitter" and "Central Electronics 10A" with your browser. 73!

This decision was made in April 1952 and eventually became an IARU standard - but its origins are surprisingly technical. The standard came out of two totally unrelated design decisions, made by different people on different continents, and at different times in the late 1940s. Those post-war years saw a rapid development in intercontinental HF telephone links. These links used independent-sideband (ISB) modulation to carry two separate voice channels on opposite sidebands, and a major manufacturer of ISB equipment at this time was the Marconi company. The ISB signal was created by up-converting two separately generated USB and LSB voice channels to the same suppressed carrier frequency, and the Marconi engineers made the smart decision to generate the ISB signal on 10.000MHz (a frequency on which they would never need to transmit, because it was already occupied by beacons such as WWV). For transmitted frequencies above 10MHz, Marconi used a crystal-controlled LO that was 10MHz below the output frequency; so the IF frequency was added to the LO and the two independent sidebands remained "the right way up". But for transmitted frequencies *below* 10MHz, the LO frequency was 10MHz *above* the output frequency; so the IF frequency was *subtracted* from the LO and the opposite sidebands were *inverted*. In an ISB system, that meant that the two telephone channels might very easily become swapped, so station engineers all around the world needed to be sure when to flip the appropriate switches. Out of these working arrangements between engineers, a worldwide CCIR standard emerged that 10MHz would be the frequency where the sidebands in ISB systems changed over. So what has this to do with amateur SSB? Amateur development in the late 1940s quickly followed the developments in commercial world - and sometimes involved the same individuals. A major influence was the W1DX SSB exciter, published in 1949, which automatically produced a sideband inversion between 80m and 20m. The W1DX design used the phasing method which allowed easy sideband selection by flipping a switch at AF, but by the early 1950s there were also many filter-method exciters that were not so agile. By 1951-52, experimenters in Europe and the USA were beginning to talk to each other on 20m, and quickly realised that they were heading for a mess. Most people were using USB on 20m, but there was no international agreement on 80m... and what about the other bands? >From eyewitness accounts, April 1952 was the moment when the agreement crystallized as we know it today. The two key points in this history are: amateurs were *already aware* of the commercial dividing line at 10MHz; and the popular W1DX exciter was *already compatible* with the new proposed standard [1]. And so it was that two entirely separate and obscure design decisions - by Marconi engineers and by W1DX - came together to create the standard that we have today.

To prevent flat-topping at 100% mod, for AM the carrier power should be no more than 25% of the peak envelope power. So I would imagine both amplifiers would do AM without the slightest difficulty.

The "9 and 5" scheme gave you 20 and 80 [and I'm not sure when phone on 40 was authorized in the US], but rigs such as the Swan 500 in the early 60's generated SSB at 5.500 MHz with additional VFO frequencies to hit 40, 15, and 10 as well. I was originally licensed in '53 but had been listening since mid '51 and the "LSB below 10 Mcs, USB above" convention was thoroughly and firmly established by then.?

What I don't know and cannot test is what USB device code is produced by the SignaLink. Normally a sound card is recognised by the linux kernel but in some cases it isn't Try to open a terminal screen (Ctrl-Alt+T) and type: lsusb That will list the available USB-ports in Linux and any asociated device. On the other hand: If the PC is a desktop and has both a line in and headphone out, use these to route audio to and from the KX3. WSJT-X produces an audio tone that is transmitted as a carrier by the KX3 and receives an audio tone from it, hence the dial setting and the use of Upper Sideband. In Mint, audio in and out can be set by right clicking on the speaker-icon and choose audio-settings from the drop down menu. There is no need to set the audio to 48000 Hz in the config. I have never done this and WSJT-X, to me, works as advertised. Even on my Raspberry Pi and an external Creative XFi USB soundcard. Of course YMMV 73, Peter Op 2018-02-14 07:18 schreef Aaron K5ATG: > I'm using a Signalink USB.

The path is from the K3 to the Microham III USB interface, then there is a straight USB connection from the Microham to the PC. I have downloaded the K3 Utility and tried to see if it will establish connection with the PC but it will not. COM port 1 is used. The K3 setting is currently at 38400 baud but I also tried setting the K3 baud rate at 4800 and doing a power on/off but with the same results. I see the K3 utility screen on the PC step through the various baud rates but it will not sync up to the K3. The PC recognizes the Microham USB interface when looking at the Win 7 Device Manager but it indicates there is no device driver. I don?t always trust what the PC says though.

If you have something like that on your shelf and it needs a new home, please contact me directly (off the reflector). 73/jeff/ac0c alpha-charlie-zero-charlie www.ac0c.com From alorona at sbcglobal.net Fri Feb 16 14:46:04 2018 From: alorona at sbcglobal.net (alorona) Date: Fri, 16 Feb 2018 12:46:04 -0700 (MST) Subject: [Elecraft] UHF connectors [was: Array Solutions Lightning Arrestor] In-Reply-To: <1d3490cc-9575-0653-18ad-e9dc5f4a5d09@sonic.net> References: <361248276.5807730.1518378588322@mail.yahoo.com> <1d3490cc-9575-0653-18ad-e9dc5f4a5d09@sonic.net> Message-ID: <1518810364222-0.post@n2.nabble.com> Hi, Okay, I thought your measurements were like S21 and could be considered a transmission (thru) loss. The other measurements I referred to were -- in other words, I don't believe they were measurements of 'mismatch loss'. The Times Microwave loss figure was definitely a transmission loss. I think it's clear that UHF connectors, at HF, are virtually lossless.

Just put the KX2 in the case and it is a GREAT fit!! Lots of room for paddles, earbuds/headphones, wire antenna. The nice thing is that the entire station (in a baggie) will slide gently into my small backpack and it will be very well protected between the padded LowPro case and the padding on the backpack. Now all I need is a summit! The bottom end of the A-Trail is just north of where we live, so in addition to attending a Cowboy Action match in the upcoming weeks, I can waddle up to a summit and give this SOTA thing a try! God Bless the brain trust at Elecraft for turning out such an astounding product! Flashback to the late 1950s and the TV show: Captain Midnight and the Secret Squadron......He had a tiny HT (probably UHF FM) and I use to dream of being able to talk all over the world with a tiny radio!

If that is the case, then you will only need to look at the MicroHam, the serial cable from the Microham to the K3 and the cable between the computer and Microham.

Joe can answer this best. Using the K3 utility with the MicroHam, is not something you generally want to do. Many of the commands are not part of the Elecraft serial port API. I know that in the past when Win4K3Suite was being developed, the MicroHam would not pass P3 commands and Joe was kind enough to add these commands to the router firmware. Now in the case of the K3 Utility, many of the commands are not published and therefore might not be passable through the serial port. Use of the K3 utility though any software router is not recommended and you might brick your K3. That being said, VMWare fusion will pass all USB ports through to the Windows 7 virtual machine. You must first plug them into the Mac OS and make sure they work there. Then you start up your virtual machine and make sure you have enabled and connected the USB devices in the VMWare settings (I think there is a tab on the top to do so.) If this is not done, then no ports are available. Hope that helps. 73 Tom va2fsq.com -----Original Message----- From: Don Wilhelm Sent: Friday, February 16, 2018 5:55 PM To: Greg Best ; elecraft at mailman.qth.net Subject: Re: [Elecraft] MICROHAM USB III INTERFACE WITH K3 UTILITY DOES NOT WORK Greg, Do you have a USB to serial cable other than the MicroHam?

If not, you will not transmit properly. See the article on my website www.w3fpr.com. Scroll down in the left column to the last article and click the link. Ignore the recommendations on the internet and many data mode applications to set the power to max and adjust the power with the audio level - it just does not work that way with Elecraft transceivers. 73, Don W3FPR On 2/18/2018 5:00 PM, James Bobo wrote: > Just trying to get on FT8 with K3.

You must set the K3 KEY-PTT menu to the correct setting (depends on the PTT setting you have chosen in your software application. If the red TX indicator does not turn on, you have not set it correctly. OTOH, using PTT via CAT command works reliably (with PTT-KEY set to OFF-OFF), and I recommend that. Alternately, VOX works reliably in DATA modes, so that is a good second alternative. If the TX LED turns on, the K3/K3S/KX3/KX2 is in transmit mode (so no problem with that), but if you do not get proper transmit, check the audio levels as I indicated in the last 2 emails I have sent on this subject. Two different problems - 1) failure to turn on transmit (PTT problem) and 2) Insufficient (or excessive) audio from the soundcard. Each one has its separate indicators. 73, Don W3FPR On 2/18/2018 7:14 PM, Michael Eberle wrote: > I am assuming you are running WSJT-X. > > I don't think you can use the same COM port for the CAT Control and PTT > Method.?

With the radio disassembled to the main pc board, (sans everything that can plug into the main board) and power applied thru the 1/8? coaxial power connector power doesn?t seem to get beyond that. I am not in a place where I can get more parts out on the bench, nor the equipment except for a cheap digital Voltmeter.

Looking for opinions on whether my solution aligned to your experience(s). I have a complete station - a KX3, a PX3, and a KXPA100. The KXPA100 is connected via a Cables On Demand connector with a PL259 on one end and a BNC connector on the other end. All other interface cables are Elecraft standard. This is NOT the first BNC connector that I've used. Prior to this last acquisition I had a couple of other BNC to PL259 jumpers that I was using, and the usual smattering of connectors and adapters in the junque box. No matter which one I used, If I removed the BNC connector from the rig (maybe to go portable, for example, or the last time it was because I installed Eneloop Pro batteries to the internal battery holders) I would put everything back together, and then would have severe - almost debilitating - signal attenuation when I got the rig fired up. If I twisted and spun the BNC connector on the jack, it would improve, and then get bad again more often than not. It could take up to 20 minutes to get everything "dialed in" so that the signal was appearing again. God help me if I accidentally moved something after that. And of course, while all this was happening the ATU was having fits, with 99:1 SWR readings and the amp was going offline; all kinds of weirdnesses. After things calmed down. the ATU behaved itself, the amp stopped being pouty, and all was then good. Thankfully, now that I have the Cables On Demand product, things seem to have quieted down - although I still don't disconnect without provocation. :) Though I'm desperately afraid of when I start to go mobile after the snow melts and the weather gets nice again. :) Hope I can get my IC706 fixed and back in service as my base station before that occurs. My question was going to be in desperation more than anything else if this last cable didn't work, but thankfully, that's been the only cable vendor that I trust for any of my specialized cables and they haven't failed me even with this one. Are BNC connectors that finicky? Is it possible that I just had a bad batch of low quality jumpers? I'm just wondering if anyone else has had excessive fiddling with their BNC connections. --- 72, Rich Hurd / WC3T / DMR: 3142737 PA Army MARS, Northampton County RACES, EPA-ARRL Public Information Officer for Scouting Latitude: 40.761621 Longitude: -75.288988 (40?45.68' N 75?17.33' W) Grid: *FN20is* From dick93117 at gmail.com Mon Feb 19 12:09:00 2018 From: dick93117 at gmail.com (RICHARD Martin) Date: Mon, 19 Feb 2018 09:09:00 -0800 Subject: [Elecraft] BNC connector oddity on KX3 In-Reply-To: References: Message-ID: Sometimes the center pin of the male BNC will get pushed back into the Teflon insulator.

During the 1960s, the easiest way to manufacture 75 ohm BNC connectors was to significantly reduce the center pin diameter from the 0.053 +/- 0.001 inch diameter specified by M IL - C - 39012. The problem is that the non-standard smaller pin does not fit properly into 50 ohm sockets or modern 75 ohm sockets using the standard 0.053 inch center pin opening. Modern 75 ohm BNC connectors now use the standard 0.053 inch center pin diameter. Unfortunately some cheap import BNC connectors and inter-series adapters still use non-standard small diameter center pins. If you have any obsolete 75 ohm BNC connectors (male or female) its best to throw them in the trash before you accidentally introduce them into your station, causing unreliability exactly as you describe in your email. Some readers will insist that BNC connectors were never manufactured with small diameter pins, but I have a few that I keep on hand -- that I clearly marked as "do not use" -- just to prove the point. 73 Frank W3LPL ----- Original Message ----- From: "rich hurd WC3T" To: kx3 at yahoogroups.com, elecraft at mailman.qth.net Sent: Monday, February 19, 2018 4:54:37 PM Subject: [Elecraft] BNC connector oddity on KX3 Hi, I had an oddity with hooking an antenna to the BNC connector on my KX3 that happened enough times to be chalked up to something other than random chance.

Unless the cable has an improperly installed connector or the cable is damaged, then and the BNC connection becomes intermittent it is usually because the female has become spread out. The solution is to just tighten it with a fine pick. We used solder picks but a dental pick is even better or a small pocket knife. I had that problem with my P3 using the factory cable. Elecraft replaced the cable. Then replacement cable became intermittent. I tightened the female pins. Haven't had an issue since. My P3 was ordered as soon as the P3-kit was announced. I should have remembered the issue before bothering Elecraft. Long ago - when we first started using BNC connectors instead of PL259 for video we discovered the hard way that you should not intermix 50 ohm & 75 ohm BNC male connectors in the plant. Prior to that time we only used BNC for RF; so our connectors were 50 ohm. We had ended up with both types in the BNC bin. We weren't the only station to trouble shoot this issue. It was a problem we discovered along with many other engineering departments. The good news is that the male center pin on BNC cables have been standardized to eliminate the issue; but cable assemblies with the smaller center pin are still out there. We had a home made gauge that we used when we changed brands or part numbers ordering BNC male connectors just to be sure. 73 George AI4VZ -----Original Message----- From: rich hurd WC3T Sent: Monday, February 19, 2018 12:51 PM To: Ken G Kopp Cc: Elecraft Subject: Re: [Elecraft] [KX3] BNC connector oddity on KX3 Well, if I did, then it's been placed into quarantine now. :) > Rich ... > > Any chance you have one or more 72 ohm BNC connectors and/or adapters? > > They -are- different than 50 ohm ones. > > 73! > > Ken Kopp - K0PP From bill at w2blc.net Mon Feb 19 14:09:13 2018 From: bill at w2blc.net (Bill) Date: Mon, 19 Feb 2018 14:09:13 -0500 Subject: [Elecraft] K-pod VFO not smooth In-Reply-To: <911e3d73-3f37-89f9-508a-80aec7ce99ca@triconet.org> References: <911e3d73-3f37-89f9-508a-80aec7ce99ca@triconet.org> Message-ID: <6f2e0283-5777-1697-e04d-55e3c50c1a4a@w2blc.net> I have had excellent service from my K-Pod.

I don't know why this works, but it does. I tried everything I could think of to get CAT control to work without success.? If you get it working please let us know how.

While it is possible that the "serial" cable may have been the the problem, that could have damaged the KIO2 (or KPA100), but it could also have damaged the MCU (U6) on the control board. Did it go into transmit with no load? If so, it may be that Q7 and Q8 have been damaged. Check the resistance from the collector to ground. It should start out at about 2k ohms and increase in resistance as the electrolytics charge. If it is substantially less than that, the PA transistors may have been damaged - that will trip the internal resettable fuse (F1). To remove 12v power from the PA transistors, you can remove them (do that if the resistance check reveals them to be shorted), or you can remove transformer T3. After removing 12v from the PA transistors, see if the K2 powers on. I don't know of anyone who is skilled in troubleshooting the K2 in central FL, but someone may volunteer. If you remove the PA transistors and do not have adequate desoldering ability, clip the leads at the transistor bodies and remove the leads one at a time. Clean up with solder wick and if solder remains in the holes, heat the pads and push the solder out with a wooden toothpick. Replace the PA transistors with the K2PAKIT from Elecraft - it has matched PA transistors. I can give you some tests to check with the PA transistors out to check whether transistors Q11 and Q13 are OK (they are included with the K2PAKIT). 73, Don W3FPR On 2/19/2018 10:20 AM, David Perrin wrote: > Hi- > > Two questions? > > After 18 years my K2 doesn?t turn on.

Antenna analyzers are often, but not always, connected at the input end of a transmission line, normally where it's connected to the transmitter and report the load characteristics the TX will see.?

Connect the TX monitor in line with the antenna. It will show the unmatched SWR and power to the antenna (the SWR will not change with the tuner settings), but serves as a monitor on any changes (faults) happening in your antenna system. If the SWR changes, there is a problem with your antenna. With the KPA500 and KAT500, you could place the monitor between the KPA500 and the KAT500 and see the SWR that the KAT500 has provided - but that information is also available on the KAT500 LEDs. With the TX Monitor placed between the KPA1500 ANT output and the antenna, the thing to monitor is *changes* in the SWR (not for an SWR of 1-1). A change in SWR of the antenna indicates something has changed in your antenna system. The LEDs on the KPA1500 will indicate the SWR match achieved by the ATU, and can be believed - no need to duplicate that SWR on the TX Monitor. 73, Don W3FPR On 2/19/2018 8:38 PM, Bill Wiehe via Elecraft wrote: > I have been looking over?the on-line manual and I unable to find any reference that explains how one will connect the P3TXMon Option Coupler to KPA1500 in order to measure power and swr.?Does anyone have any insight. > Thanks,Bill - W0BBI > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to donwilh at embarqmail.com > From donwilh at embarqmail.com Mon Feb 19 21:39:18 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 19 Feb 2018 21:39:18 -0500 Subject: [Elecraft] K2 is dead?

At the current time, I am doing support for Elecraft as well as both Elecraft repairs and independent repairs for the Classic (legacy) gear - the K2, K1, KX1 and XV series tranverters. All that keeps me quite busy and my turn-around time on repairs has slowed since I have been also doing support activities via both email and phone directly for Elecraft. Be that as it may, I still do many repairs of the K2, K1, KX1 and XV series tranverters, but my turn-around time has slowed a bit because of my other activities. Send me a direct email (w3fpr at embarqmailcom) asking for my service and I will send you my service form. If you prefer to go through the official Elecraft repair channel, send an email to support at elecraft.com and ask for an RSA number and form - wait until you have received the RSA number and shipping instructions before sending your K2. RSA repairs of the K2, K1, KX1 and XV series transverters are not done in Watsonville, but at my address in North Carolina, or possibility by Gary in Arizona. 73, Don W3FPR On 2/19/2018 8:55 PM, Ken G Kopp wrote: > I'll add my enthusiastic endorsement for Don, W3FPR.

I understand the reluctance to use that terminology, but strictly speaking you're wrong.? Reactance networks are reciprocal ... they don't care in the least which direction power is heading.? The combination of the feedline, the "antenna tuner", and the output impedance? of the transmitter reflect back along the feedline to the antenna the same reactance that you would use at the antenna feed point to zero out the total reactance there ... i.e., "tune" it.? The only difference lies with their respective losses., and if you had lossless feedline and lossless components there would be no difference at all. It's basic network physics, and reciprocity is reciprocity. 73, Dave??

I _think_ every modern OS uses an NTP implementation or at least has one available. Some light: https://en.wikipedia.org/wiki/Network_Time_Protocol and not so light: http://www.ntp.org/ https://www.eecis.udel.edu/~mills/papers.html reading for those who don?t know about NTP. I?d be interested to hear about ones that: a) don?t have an NTP implementation available and/or b) have one that does not work reliably One issue I?d keep an eye on is whether your OS (and it?s NTP daemon) will tell you if it?s having trouble syncing. With a good NTP implementation, you could go months (or years) with no significant time of day error and then loose your time sync and slowly drift off to the point that it matters for your application. You can also run into this problem if you are off the ?net and the NTP daemon can?t get to the NTP source often enough. -Dale > > wunder > K6WRU > Walter Underwood > CM87wj > http://observer.wunderwood.org/ (my blog) > >> On Feb 20, 2018, at 8:55 AM, John Stengrevics wrote: >> >> Richard, >> >> I run a Mac here.

This results in the clock drifting significantly from our perspective, but "not enough for the average user to care about." It can definitely be enough for JT modes to care about. I tracked my clock accuracy at one point on OSX 10.9 (I think), and as I recall I saw it drift up to 20 seconds at some points in time. I'm unsure if it's been improved in the most recent macOS releases, but the idea of forcing a restart of NTP either daily, or whenever you fire up WSJT-X, hasn't necessarily been as much of a faux pas as one might think. -detrick K4IZ On Tue, Feb 20, 2018 at 12:49 PM, Dale Chayes wrote: > > > On Feb 20, 2018, at 12:06 , Walter Underwood > wrote: > > > > Should not need to unlock and relock daily.

However, even when I doreboot occasionally, any transient loss of sync to the NTP servers doesn't seriously affectme when I use WSJT-X. OTOH, since I spend a lot more time listening than transmitting,while searching for "new ones", NTP has plenty of time to sync back up :-) I suppose if you want to really go overboard, you could get yourself a GPSDO and theninstall gpsd (GPSd ? Put your GPS on the net!) and NTPsec (Welcome to NTPsec)and then you'd not only be good-to-go for the WSJT-X modes, but you could then serveup a reference for the rest of us. Both of those can, AFAICT, be built for Windows,Linux and macOS, assuming you have the software development tools (compiler,linker, libraries, etc.) installed. BTW, NTPsec is a new/rewritten implementation of NTP that is far more secure and robust,and does not need gpsd or a GPSDO to use. If you're concerned that your currentOS/computing environment might not be behaving as well as you'd like with respect to NTP,it might be worthwhile to take a look at NTPsec.

Here?s the first part: ----------------- Mac mini running Sierra 10.12 New K3S Using USB cable only WSJT-X version 1.8.0 Primarily FT8 for the moment Major Problem #1: Communication between the software and the K3S is unstable and unreliable. For example ? When the software goes into Transmit right on the button, the K3S power comes on 2 to 3 full seconds later. When the software comes out of Transmit right on the button, the K3S keeps transmitting for 2 to 3 seconds. Sometimes the K3S NEVER stops transmitting. Sometimes the software goes into Transmit, but the K3S doesn?t transmit at all. Fun, huh? ??????

This can also happen if the spotting station is in split mode when the spot is sent to packet. You can prove this to yourself. Type a call into the call sign field of the Entry window. Put the K3 in split mode with the sub vfo a kHz or two away. Now just tune the main vfo away and watch the self-spot go into the bandmap. Take the K3 out of split mode. Use Ctrl+Up or Dn arrow and jump back to that spot. The K3 will go back into Split mode with the same offset as when you spotted it. Similarly, if the radio is in the split mode and you click on a non-split spot, it will cancel the split on the radio.

When teaching newbies the wrong phrase can cause problems that are not seen till later. Antennas are tuned with wire cutters or a hacksaw so the feed impedance is the desired value, ideally 50 ohm resistive or at least a match for the feeder concerned. Of course that is not always practical so an antenna matching unit brings the antenna or antenna plus feeder input impedance to the value wanted by the transmitter. Too often I have seen students believe the ATU alters the current and voltage distribution on the antenna so it looks exactly like the distribution on a dipole of the correct length for the frequency concerned. Granted the currents and voltages might change as the ATU is adjusted but that does not make the antenna radiate more efficiently. The reflection at the feeder/antenna junction is unchanged. In training we use the term antenna matching unit, AMU, to avoid best we can the students starting off with the wrong impression. Amongst ourselves we can get away with slack terminology, we all know what is meant; in front of trainees it is a different story. 73 Alan G0HIQ From rick at tavan.com Tue Feb 20 20:26:25 2018 From: rick at tavan.com (Rick Tavan) Date: Tue, 20 Feb 2018 17:26:25 -0800 Subject: [Elecraft] K3 with N1MM - SPLIT mode In-Reply-To: <006001d3aaa2$389ccb60$a9d66220$@verizon.net> References: <02ac01d3aa77$5d8f2a10$18ad7e30$@verizon.net> <00e601d3aa8c$de84b9e0$9b8e2da0$@comcast.net> <006001d3aaa2$389ccb60$a9d66220$@verizon.net> Message-ID: I think what counts is not the way the target station is operating but rather the way the spotter station is operating. If the spotter had Split engaged, for example to dither its calling frequency in order to stand out in the pileup, then the spot may specify split and cause your symptom, even though the DX station is operating simplex on a single freq. This won't happen all the time - it's a complex interaction among the spotter's rig, operating mode, logging software, Telnet interface, and your Telnet interface, rig, logging software, and settings. I don't think there is anything you can do about it except be aware. (Or maybe you can convince all the hams in the contest to use RIT/XIT/CLAR instead of Split when calling a simplex pileup? Good luck! And RIT/XIT/CLAR can provoke some frequency anomalies of their own.) 73, /Rick N6XI Rick Tavan Truckee, CA On Tue, Feb 20, 2018 at 3:26 PM, N2TK, Tony wrote: > Hi Ted, > All of the stations that I clicked on the bandmap were operating > transceiver.

Frequently a feed line does NOT have a low SWR by design. It is still a feed line in that it carries RF from the transmitter site to the radiator with a minimum of radiation from itself. A classic example is the Zepp antenna: a 1/2 wave long radiator fed at one end with a 1/4 wavelength long open wire feed line. The SWR on the feed line is intentionally very high because its function is to translate the very high impedance at the end of the radiator to a low impedance easily handled by the transmitter, nowadays generally using a matching network commonly called a "tuning unit" since modern transmitters are designed for a 50 ohm non-reactive load. Another example is a wire radiator fed at the center with open wire feed line for operation on a variety of bands. Again the SWR in the feed line will be very high, depending upon the length of the radiator, the length of the feed line and the frequency of operation. But, using a feed line with an impedance of 450 to 600 ohms, the SWR in a real-world H.F. installation where the radiator is at least 1/2 wavelength long at the lowest frequency of operation, the SWR on the open wire feed line will not exceed about 20:1 so the losses will be very low. The real advantage to this setup is that the matching network can be in the shack and within easy reach of the operator instead of being mounted remotely at the center of the radiator. I present the use of 50 ohm coaxial line without a matching network as a "special case" where it possible to design a radiator or system of radiators that presents an impedance at its feed point that is a close enough match to 50 ohms without the network. However, using a low-impedance like such as the common coax means we must pay special attention to the SWR on the feed line to avoid excessive losses. For example, with 50 ohm coax in an HF installation, it is easy to realize an SWR of greater than 100:1 and very high losses. In such a case a matching network at the transmitter will not reduce the feed line losses. 73, Ron AC7AC On 2/20/2018 8:16 PM, Alan B via Elecraft wrote: > This all depends on what is meant by antenna tuning. > When teaching newbies the wrong phrase can cause problems that are not seen till later. > Antennas are tuned with wire cutters or a hacksaw so the feed impedance is the desired value, ideally 50 ohm resistive or at least a match for the feeder concerned. > Of course that is not always practical so an antenna matching unit brings the antenna or antenna plus feeder input impedance to the value wanted by the transmitter. > Too often I have seen students believe the ATU alters the current and voltage distribution on the antenna so it looks exactly like the distribution on a dipole of the correct length for the frequency concerned. > Granted the currents and voltages might change as the ATU is adjusted but that does not make the antenna radiate more efficiently.

However, using a low-impedance like such as the common coax means we must pay special attention to the SWR on the feed line to avoid excessive losses. For example, with 50 ohm coax in an HF installation, it is easy to realize an SWR of greater than 100:1 and very high losses. In such a case a matching network at the transmitter will not reduce the feed line losses. 73, Ron AC7AC On 2/20/2018 8:16 PM, Alan B via Elecraft wrote: > This all depends on what is meant by antenna tuning. > When teaching newbies the wrong phrase can cause problems that are not seen till later. > Antennas are tuned with wire cutters or a hacksaw so the feed > impedance is the desired value, ideally 50 ohm resistive or at least a match for the feeder concerned. > Of course that is not always practical so an antenna matching unit > brings the antenna or antenna plus feeder input impedance to the value wanted by the transmitter. > Too often I have seen students believe the ATU alters the current and voltage distribution on the antenna so it looks exactly like the distribution on a dipole of the correct length for the frequency concerned. > Granted the currents and voltages might change as the ATU is adjusted > but that does not make the antenna radiate more efficiently.

In fact it adds additional system loss due to loss incurred in the tuner. If the transmitter can not deliver rated power into the load that is a different issue to resolve. The ATU may accomplish this, but with added system loss.

At least in my world, tuning refers to compensating for reactance at the feedpoint by some means that nets it out to zero.? In that respect, doing so with a network at the other end of the feedline accomplishes the exact same thing as using wire cutters or a hacksaw on the antenna itself.? They are not different.???? As you say, the current and voltage distributions are not the same as if you cut the antenna to length, but the lack of feedpoint reactance is. Matching the feedpoint impedance to the feedline, or compensating the effects of the mismatch at the transmitter end, is an entirely different matter and there is no requirement that "tuning" per se accomplishes a match at either end ... only that it bring the reactance at the antenna to zero.? We do, of course, also want our "antenna tuner" to give us the proper match, and in common practice that's what it does.? In that regard, calling it an "antenna tuner" only tells part of the story and "antenna coupler" might be a more rigorous term ... more rigorous even than "antenna matching unit." 73, Dave??

They are not. Yep.? And many antennas are better matched to other than 50 ohm feedlines. My high dipoles are in the range of 85-90 ohms, so I use a good RG11 to feed them. And those dipoles are for 80 and 40M, so their lengths are tweaked so that, with stub matching in the shack, the Z presented to the 87A (tube) power amps is within the range they are happy feeding. > At least in my world, tuning refers to compensating for reactance at > the feedpoint by some means that nets it out to zero.? In that > respect, doing so with a network at the other end of the feedline > accomplishes the exact same thing as using wire cutters or a hacksaw > on the antenna itself. Don't agree with that -- the match between the antenna and the feedline determines the loss in the feedline. The tuning network between the transmitter and the feedline does NOT change the loss in the feedline, it simply gives the transmitter a load that it's happy driving, and to which it can deliver maximum power.? AND -- we are NOT matching the antenna Z to the TX output Z -- for most real transmitters, their output Z is LESS than the load they are designed to drive, and that output Z changes dynamically with signal level! Back in the olden days, we young EEs learned about how do determine this with "load lines." > They are not different.???? As you say, the current and voltage > distributions are not the same as if you cut the antenna to length, > but the lack of feedpoint reactance is. But with most antennas, zero feedpoint reactance can be achieved at only one frequency -- it takes something like a SteppIR to move that zero point around the band. I may resonate my 80M dipole at 3625, but I almost never operate there. Rather, I'm mostly between 3500 and 3600, and between 3650 and 3850. And then there are directional antennas like Yagis. :) 73, Jim K9YC From Gary at ka1j.com Wed Feb 21 02:05:40 2018 From: Gary at ka1j.com (Gary Smith) Date: Wed, 21 Feb 2018 02:05:40 -0500 Subject: [Elecraft] OT Power Strip suggestion.

These devices use MOVs to conduct the surge to the Green wire, and that ANY surge protector that does that raises the voltage on the chassis of the equipment to a VERY high level. When that equipment is connected to equipment plugged into a different outlet, the DIFFERENCE in potential between the two pieces of gear is very likely to fry circuitry in both of them. The ONLY safe place for MOV protection is at the service entrance -- the "whole house protector."? The only safe protection on a branch circuit (that is, anywhere else) is a SERIES MODE protector. Series-mode protectors store the surge in a big inductor, then slowly discharge them after the surge has ended. They are widely used in pro audio systems, which have many interconnections between equipment. That industry uses protectors made by Surge-X; a company called Brick Wall is a competitor that focuses on the home entertainment market. I use Surge-X units in by home, office, and ham station. I've done consulting work and technical writing for Surge-X, but I was specifying their products for the large audio systems I designed at least ten years before they hired me for technical writing and teaching at industry trade shows. In other words, my recommendations are professional, not based on a business relationship, and I haven't done anything for them for about four years. There are more detailed tutorials about this on my website. I wrote http://k9yc.com/SurgeXPowerGround.pdf The next two links are for a 4-hour tutorial workshop that Andy Benton and I taught at Infocomm for 6-8 years. Andy and I collaborated on http://k9yc.com/InfoComm-PowerSystems2012.pdf and the material on surge protection is Andy's work.? There's nothing in it that I disagree with. This one is all mine. http://k9yc.com/InfoComm-Grounding2012.pdf This slide deck focuses on our ham stations. It served as much of the basis for N0AX's excellent ARRL book on the topic. http://k9yc.com/GroundingAndAudio.pdf Bottom line -- proper grounding and bonding is FAR more important than surge protectors. Good surge protection isn't cheap, but cheap surge protection is more likely to CAUSE equipment failure than to protect against it. If you don't want to spend the bucks, do the proper grounding and bonding, which is, essentially, free. The "whole house" units take care of strikes coming in on the power line, the branch circuit units take care of what's picked up on wiring within the house. The whole house protector I'm using is made by Joslyn. I didn't do research to find it -- a fellow ham bought some at a good price and offered them to me. It's a high quality unit. 73, Jim K9YC On 2/20/2018 11:15 PM, hawley, charles j jr wrote: > These were always thought to be the best. > > https://www.tripplite.com/isobar-8-outlet-surge-protector-12-ft-cord-3840-joules~ISOBAR8ULTRA From lsierdsma at gmail.com Wed Feb 21 08:53:32 2018 From: lsierdsma at gmail.com (Laurens Sierdsma) Date: Wed, 21 Feb 2018 13:53:32 +0000 Subject: [Elecraft] For sale: Elecraft K3 plus P3 panadapter Message-ID: For sale: Elecraft K3/100 plus P3 panadapter #5996 KDVR3 (Voicekeyer) KAT3A (Antennetuner) KXV3B (RX Ant, IF Out & Xvrtr Int) Included P3 2400 Euro?s Without P3 1800 Euro?s Email for more info or pictures 73 Laurens PD9X From rmcgraw at blomand.net Wed Feb 21 09:19:09 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Wed, 21 Feb 2018 08:19:09 -0600 Subject: [Elecraft] OT Power Strip suggestion.

You can find those that automatically reset. They are a bit more expensive. https://community.spiceworks.com/topic/1525772-ups-power-state-after-power-loss-and-battery-depletion "As batteries begin failing, automatic restart back into a protected operating mode when power is restored becomes more challenging for the UPS to provide. You can overcome it by ensuring that your battery set is frequently tested and replaced well before failure. What else can you do to ensure that your application will restart automatically when power is restored? Get a UPS with BATTERY INDEPENDENT RESTART ability. UPS systems that include this feature will restart back into a protected UPS-enabled operating mode when power is restored, so long as batteries are in good-enough shape to provide protection. If batteries aren't in particularly good health when power is restored, a UPS with BATTERY INDEPENDENT RESTART will automatically begin passing BYPASS OUTPUT to power your connected equipment right-away after power is restored, regardless of the condition of the battery set. While bypass isn't a protected operating mode (it won't provide UPS protection), it's better than nothing! This allows your applications to begin operating right away." 73 de Brian/K3KO On 2/21/2018 15:13 PM, Reed wrote: > Gary I have used APC UPS for over 23 years on all electronic equipment > including my XYL'S Bernina sewing machine.??

If the spotter had Split engaged, for example to dither its calling frequency in order to stand out in the pileup, then the spot may specify split and cause your symptom, even though the DX station is operating simplex on a single freq. This won't happen all the time - it's a complex interaction among the spotter's rig, operating mode, logging software, Telnet interface, and your Telnet interface, rig, logging software, and settings. I don't think there is anything you can do about it except be aware. (Or maybe you can convince all the hams in the contest to use RIT/XIT/CLAR instead of Split when calling a simplex pileup? Good luck! And RIT/XIT/CLAR can provoke some frequency anomalies of their own.) 73, /Rick N6XI Rick Tavan Truckee, CA On Tue, Feb 20, 2018 at 3:26 PM, N2TK, Tony > wrote: Hi Ted, All of the stations that I clicked on the bandmap were operating transceiver.

On the spots that you clicked on and the K3 went into Split mode, were the spotted stations actually operating split? This can also happen if the spotting station is in split mode when the spot is sent to packet. You can prove this to yourself. Type a call into the call sign field of the Entry window. Put the K3 in split mode with the sub vfo a kHz or two away. Now just tune the main vfo away and watch the self-spot go into the bandmap. Take the K3 out of split mode. Use Ctrl+Up or Dn arrow and jump back to that spot. The K3 will go back into Split mode with the same offset as when you spotted it. Similarly, if the radio is in the split mode and you click on a non-split spot, it will cancel the split on the radio.

The sale helped nudge me to do it now rather than later, but I had been slowly settling on that package for a month or two now. I'm currently using a Heathkit SB-1000 amp - a fine amp, but manually tuned. Plus, if I run it conservatively I usually am putting out around 600 watts. Yes, it will do a kilowatt. For a bit, and that is pushing it. So, I have worked plenty of DX and busted pileups with 500 to 600 watts. It does seem to me that I am often QSY'ing quickly so the amp isn't really peaked up, so half the time it's more like 500 watts out than 600.

As far as I know all 75 ohm BNC connectors made in the USA use the correct diameter center pin. However... This is NOT true for many import connectors and adapters, even modern high bandwidth 75 ohm import connectors often have serious design and quality control problems. I've found three categories of serious reliability problems with import 75 ohm BNC connectors and adapters. - much smaller center pin diameter, they're copies of 40 year old obsolete "made in USA" 75 ohm BNC connectors - center pin slightly too small in diameter -- a quality control or manufacturing problem that causes unreliable connections. - tapered center pin with incorrect diameter over most of its length that causes unreliable connections Don't believe me? I have modern import connectors with all three types of problems. 73 Frank W3LPL ----- Original Message ----- From: "Chris Cox, N0UK" To: "Dale Parfitt" Cc: "Chris Cox, N0UK" , kx3 at yahoogroups.com, elecraft at mailman.qth.net Sent: Wednesday, February 21, 2018 4:25:15 PM Subject: Re: [Elecraft] [KX3] BNC connector oddity on KX3 Indeed - i didn't know that.

In order to 'encourage' development, I'll now make the suggestion publicly (hey, it worked for the KPA1500 after all!). Proposal:? Since the K-pod uses the previously unused (by the consumer) plug under the from panel of the K3, I submit that it could also be used for creating a network interface board to make the K3 a network device.? I suggested an FPGA with an audio section for those older K3 without the newer interface boards; or it could be incorporated into a new(er) K3IO board.? That could standardize the audio interface; removing the need for an audio device (SignaLink being popular), simplifying the overall wiring as well.?? Upgrading to Wifi (even less wires, BONUS!) is possible too. If the K3-FPGA (or another IO board) was made, with the addition of the KPA1500, the entire K line could more easily be remoted via the network (and Internet) and managed with the appropriate software or apps for tablets/phones; withOUT requiring a computer to manage them at the station (one less common point of failure, less energy used).? It could be in essence, a QRO version of the, uh, another known brand. Existing software (HRD being popular) could be updated to include IP addressing instead of COM ports (HRD would be simple, it's already IP based) and device apps for tablet/phones could follow. Yes, one can go the route of a K3/0 if one required knobs to turn, but having the complete K line network capable means less to pack (or lose), less weight when traveling (or if operating from another room).? Making it network capable also means one could put the station in a closet or more easily in an RV compartment and still have a functioning station (XYL approved, peace survives in the house). In the meantime, I use TeamViewer and Skype (via the SignaLink USB) AND a station computer to manage things remotely.? While it works and is awesome, I've had some issues with USB in an RF environment, which includes the SLUSB.? Those issues are a challenge to tame so a network based interface really appeals to me (I operate remotely, often and QRO). Caveat:? There may be a better/simpler way to get this done than an FPGA board, but I'd bet a network interface device (with audio) would be cheaper than a K3/0 for those willing to shed knobs and buttons.? The wizards and Elecraft are much more informed and capable than I'll ever be, so let's be hopeful of this path. 73, Rick WA6NHC From w5rg at yahoo.com Wed Feb 21 17:48:44 2018 From: w5rg at yahoo.com (Bob Gibson) Date: Wed, 21 Feb 2018 22:48:44 +0000 (UTC) Subject: [Elecraft] POWER LOCKED References: <1800491276.3283313.1519253324247.ref@mail.yahoo.com> Message-ID: <1800491276.3283313.1519253324247@mail.yahoo.com> I just bought a used K3 and I did a update on the rig..all seems to go OK but I get a power lock and no output from the rig..What did I do wrong?

Will the K3 not power on? or can you not move the POWER knob? In either case, I would suggest you first remove all cables from the K3 except the power cable and a dummy load and see if it clears. Did you use the latest K3 Utility to download the firmware? If not, download K3 Utility from the ELecraft website and re-load all firmware (you may have to "Force a Firmware Download" see manual. If all else fails, you may have to do an EEINIT (See Reset to Factory Defaults in the manual), and then reload the firmware. If you had the K3 set up as you like it, hopefully you saved a configuration (see K3 Utility). If so, you can Restore Configuration using K3 Utility. 73, Don W3FPR On 2/21/2018 5:48 PM, Bob Gibson via Elecraft wrote: > I just bought a used K3 and I did a update on the rig..all seems to > go OK but I get a power lock and no output from the rig..What did I > do wrong?

The FW rev level is from 2008, and it?s a good bet you?re missing quite a few needed and worthwhile hardware and board-level updates as well. It might even be worth your while to send the radio to Elecraft, have them go through it, and bring everything up to date. In many ways, it will be a different (better) radio when you get it back (or do the mods and updates yourself). Enjoy ? :-) > On Feb 21, 2018, at 8:42 PM, Bob Gibson via Elecraft wrote: > > Carl..

I'm primarily a contester and dxer. I sometimes use the builtin keyers in the K3 and the Icom IC-7800. However, I do like and have several Winkeyers. They interface easily in N1MM+ on their own serial port. The speed can be controlled either from the Winkeyer speed pot or from the N1MM+ program with a mouse to change the speed. I have the standalone Winkeyer USB, also 2 of my Rig Expert interfaces have builtin Winkeyers. To me I like the stability and accuracy of the Winkeyer. It's easy to adjust the speed up or down 2wpm at a time. So boils down to personal preference and I have nothing bad to say about the builtin keyers. 73 Darrell AB2E ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of Bill DeVore Sent: Wednesday, February 21, 2018 8:52 PM To: elecraft at mailman.qth.net Subject: [Elecraft] K3S and Winkeyer I?d like to start contesting and plan on using N1MM with my K3S.

This works fine for some, but others have issues with timing (it's dependent on Windows and the COM port operating smoothly). The WinKeyer is very well regarded amongst contesters, and will generally provide the most dependable operation. 73, ~iain / N6ML From tomb18 at videotron.ca Thu Feb 22 00:17:00 2018 From: tomb18 at videotron.ca (Tom) Date: Thu, 22 Feb 2018 00:17:00 -0500 Subject: [Elecraft] K3S and Winkeyer In-Reply-To: References: Message-ID: <83FDDB83F2394DCCB39F30D00DDC887D@DESKTOPAV61F2H> One big advantage, if you play to use keyboard based CW at all, is that on the K3, you cannot use software keying using the built in keyer on the Elecraft. Instead, you need to use N1MM's DTR keying which is software based and cannot be used reliably unless you only have N1MM software running with the K3. If you use any virtual ports, it will not work reliably. A WinKey is a good solution and not expensive. Most software packages support WinKey. 73 Tom va2fsq.com -----Original Message----- From: Bill DeVore Sent: Wednesday, February 21, 2018 8:52 PM To: elecraft at mailman.qth.net Subject: [Elecraft] K3S and Winkeyer I?d like to start contesting and plan on using N1MM with my K3S.

But it depends on a lot of things. In my case, the CW got poorer when there was a lot of internet activity on the computer. Computer sound generation and other stuff also affects it.

Since I started using Win4K3, I?ve had to use alternate means. I?m planning to go with a Winkeyer type device for all the reasons mentioned by the others. I recently found the Nanokeyer project, which is a Arduino based Winkeyer clone built on the code from K3NG. I?ve got one knocked together on the workbench and it seems to work well, so I?m going to give it a workout and see if it meets my needs, as soon as I find time to move it from a mass of jumper wires and clip leads to something resembling a completed piece of equipment.

Dipole, Phone on 75, phone on 40, 20, 15 Inverted-L on 160 Yagi on 6 Mostly the antennas are below 2:1, but they need some flattening on 160, 80 and 40 if I have to go beyond their sweet spots. When I build the KAT500, what is the best use of the 3 ports available to maximize it's tuning algorithm? In other words, how can I maximize the likelihood that a band change or QSY will result in a rapid tune due to prior memorization, versus a somewhat longer full tune? My thoughts were perhaps to put the 6 and 160 antennas each on their own KAT500 port, then use the manual switch for the three that would cover HF. Fine, except there could be a situation where the KAT500 had memorized a tune for 7.100 that might be fine for the vertical but different for the dipole. The vertical is omni, so at times it would be a better choice than the dipole. Or, perhaps experienced users can tell me that the tuning works quick enough that even if I try to confuse it the KAT500 will be quick enough that it isn't an issue. 73 de Chuck, WS1L -- =================== Chuck Chandler chandlerusm at gmail.com =================== From wunder at wunderwood.org Thu Feb 22 11:02:41 2018 From: wunder at wunderwood.org (Walter Underwood) Date: Thu, 22 Feb 2018 08:02:41 -0800 Subject: [Elecraft] KX3 low volume In-Reply-To: <1883901833.3758312.1519314929643@mail.yahoo.com> References: <1883901833.3758312.1519314929643.ref@mail.yahoo.com> <1883901833.3758312.1519314929643@mail.yahoo.com> Message-ID: <1C947543-CC4D-4331-9D9B-05063C7A332D@wunderwood.org> Here is a copy of what I sent to the KX3 list less than 12 hours ago.

Connect the 2 antennas you most frequently use to their own KAT500 port, then connect the others through your switch. Since you have the vertical which covers all bands, and other bands that overlap band coverage, put the vertical on one KAT500 port. Then put either the 160m or the 6 meter (whichever band you use most) on another port. Connect the 3rd port to the antenna switch. Select the vertical and the other antenna connected to the dedicated port with the ANT 1,2,3 selection on the KAT500, then with the antenna switch port selected, you switch between the other antennas. Don't worry about the number of memories and antenna ports. The KAT500 will remember the tuning settings easily. Just don't forget to operate the manual switch when you change to a particular band. Another idea if it appeals to you and you have the subRX - use the vertical to connect to the AUX RX antenna on the K3 for the sub. That allows you to use the vertical along with another horizontal antenna for diversity reception. 73, Don W3FPR On 2/22/2018 10:56 AM, Chuck Chandler wrote: > Currently I have five antennas connected to my K3S via a manual switch: > > LPDA, 20 through 10 > Vertical, CW on 80, low end of 40, 30, 20, 17, 15, 12 and 10. > Dipole, Phone on 75, phone on 40, 20, 15 > Inverted-L on 160 > Yagi on 6 > Mostly the antennas are below 2:1, but they need some flattening on 160, 80 > and 40 if I have to go beyond their sweet spots. > > When I build the KAT500, what is the best use of the 3 ports available to > maximize it's tuning algorithm?

What I found works with nice sound reproduction is the Jam plus (Bluetooth) wireless speaker you can plug in with a 3.5 stereo (male) both ends from the headphone out of the KX3 into one of the Jam plus. They are? small great sound ( full range) if you require com audio set the RX eq up to your liking. The only draw back is mini USB port for charging will need power input for more than 4 or 5 hours of running off the internal battery. A possible solution is a back up smart phone battery to power for long periods of operating or plug it or them I have two into the USB port on you computer if you have one along. The pair of Jam Plus will connect (pair) up together via there Bluetooth so the connection to the KX3 only needs to be on one of the speakers. Paring them requires a pair of the same speaker models. I have not tried the pair on the KX3 in stereo to test? RX split like when using the headphones.

You can connect several antennas to a given port through external switches, but if two of those antennas are ever used on the same band, there is a danger that the KAT500's settings that work with one of the antennas will be wrong for the other antenna that you use on the same band/port combination, requiring the KAT500 to retune every time you switch between those antennas. To avoid this situation, you should try to make sure to the extent possible that on any band where you use more than one antenna, those antennas are connected to different ports on the KAT500. Since you have three different antennas that are used on 20 and 15, you should try to ensure that those three antennas are connected to separate ports on the KAT500. That means that the LPDA, the vertical and the dipole should all be on separate ports. In your case, once you have done that the only antennas you have left are single-band antennas that you do not use on any band that is shared with any other antenna, so you can put them on whichever port you want. If you are likely to be switching back and forth between two antennas because their bands are often open at the same time, it might be best to separate those antennas to minimize the number of times you need to operate a manual antenna switch. That suggests putting the 160m inverted L on the same port as the LPDA, to minimize the amount of switching back and forth between 160 and 80/75 (where you use the other two antennas). The 6m antenna can go anywhere; wherever you are least often likely to have to switch back and forth, e.g. on the same port as the dipole. 73, Rich VE3KI WS1L wrote: When I build the KAT500, what is the best use of the 3 ports available to maximize it's tuning algorithm?

The only niggle I have is that I need to remember to disable the ATU when using my mag loop on antenna 2 and enable it when using the end-fed wire on antenna port 1. Given that the firmware very effectively memorizes the various optimal tuning combinations for the various antennas, it woul dbe very nice that it remember whether the tuner should be enabled or disabled depending upon which antenna is selected.

By dumb luck, I bought a couple of CyberPower units that do NOT have this serious design defect, AND which are also RF quiet. The model I bought is the CP1500PFCLCD. It has RFI filtering and meets FCC Part 15 Class B. I'm guessing that I bought the first of these units 4-5 years ago, and it's been protecting a big "old iron" Dell tower ever since. Run time still seems quite good. I bought the second one a few years ago to keep low power 120V shack gear running through the occasional power drops we experience up here in the mountains. Both units are plugged into a SurgeX box.

The value is established via the F2 setup menu, Advanced page, under Miscellaneous.??? Additionally if you are using VOX control via the radio, this delay of audio is very apparent.?? I suggest you configure for CAT control.? Also, if you are using VOX the VOX delay must time out before the radio returns to receive. Depending on other applications which may be running on the computer, the lag time due to processor activity may be apparent as well. ? And there is processor timing activities within the radio which adds delay time to transitions. I find CAT control to be preferable to VOX control. 73 Bob On 2/22/2018 4:22 PM, James Bennett wrote: > Got a question about using my K3 with WSJT-X 1.8.0 with FT8 > > I started looking at the ?time bar? in WSJT-X and when the K3?s red TX light comes on with the meter showing RF going out.

Does anyone experienced this issue? PS. The PA put out 100w as it should. 73, MatteoM0TKM From john at kk9a.com Fri Feb 23 08:20:19 2018 From: john at kk9a.com (john at kk9a.com) Date: Fri, 23 Feb 2018 08:20:19 -0500 Subject: [Elecraft] OT Power Strip suggestion.

Is it possible something is autobauding? I have every thing set explicitly to 38.4K. The WSJT-S software, the com port on the computer, and the radio. Nothing is searching for speeds... Many people forget that the computer might auto search for speed if not set to the speed presented to the com port. I am running 38K speed, and have set the computer to do 38.4K as well. I would look to my computer for the delay, not the K3, unless the K3 is broken... My K3 is in RS242 B mode at 38.4K. 73s and thanks, Dave NK7Z https://www.nk7z.net On 02/22/2018 09:19 PM, Wayne Burdick wrote: > RIchard, > > There are no long delays inherent in the K3/K3S transmit timing.

The RATE button currently toggles between two rates. Could a third rate be added that changes the step to kHz (as opposed to the current .1 or .01 kHz rate)? This would greatly simplify getting from one end of the CW sub-band to the other, as is sometimes the case if I'm near 14060 and then see a DX spot for a station on 14015 for example. I know I can punch in the desired freq with the numerical buttons but I think a faster rate would be easier in actual operation.

Anything under 2:1 won't make a difference in performance. Using two 50 ohm dummy loads connected in parallel, either instrument should show a 2:1 SWR. Be sure the dummy loads are actually 50 ohms and not just labeled such.? I have one of those "gallon" type loads that measure 58 ohms cold and 64 ohms hot.? The label on the bucket says "50 ohms". A man with a watch will always know the time.? A man with four watches is never sure of the time. 73 Bob, K4TAX On 2/23/2018 8:34 AM, Roger Meadows via Elecraft wrote: > I decided to do a spot check on SWR readings on my antenna with my KX3 after I tuned it with a MFJ 259C.

Well, here is the strange thing: the iMac that the K3 is connected to consistently is giving me a DT response of 0.1 to 0.2 on 90% of the decoded stations, so I?m thinking that the default time server the iMac / OSX is connected to is pretty accurate.

My point was that in the radio, with the VOX correctly adjusted, response to a transmit command using VOX is virtually indistinguishable from PTT. Any significant delay is on the release. Agree with you that PTT is the better choice. Only mention VOX because that is what was chosen in the setup in this case. Btw, I copied your setup parameters for my K3 in the WSJT-X setup and I still get the same, consistent 1-second delay before audio is transmitted. This is not a problem, for me anyway. But those who are seeing longer, varying length delays, it's puzzling.

Have exclusively used VOX for FT8 and JT65. The 100+ countries worked apparently saw no issue either. Don't hear any predominant "others transmitting earlier". Occasionally but that may be their clock. This is with a K3 not K3S. WSJT-X has no radio chosen. I could never get WSJT-X (or JT65) to attach to the K3 via a LPBRIDGE virtual port. If I directly connect to a dedicated serial port rig/wsjtx rig connects OK. Can't live with that. Note: This is WIN7 32 bit and a slightly older version of LPBRIDGE, the latest version of WSJT-X and the computer's internal sound card. 73 de Brian/K3KO On 2/23/2018 14:19 PM, Ted Bryant wrote: > Hardly.

K3/K3S VOX is very fast on attack and can be set to very fast on release as well. It should be just as fast for data modes as for voice modes. This means you can test it by simply putting the radio into SSB mode: set the VOX delay to something small (say 0.05, or 50 ms). Set the VOX gain using the menu. If it?s slow, *then* it?s our problem.... but it shouldn?t be slow. PTT should work equally well. Wayne N6KR > On Feb 23, 2018, at 7:32 AM, brian wrote: > > Agree.

Well, here is the strange thing: the iMac that the K3 is connected to consistently is giving me a DT response of 0.1 to 0.2 on 90% of the decoded stations, so I?m thinking that the default time server the iMac / OSX is connected to is pretty accurate.

In CW mode the default is 0.1 kHz, but you can set it to something higher. This would allow you to QSY much more quickly. Another trick: Whenever the OFS knob?s LEDs are both off (RIT and B), the control does coarse control of VFO A. Assuming RATE is set to 10 Hz, this means you can do fine tuning with VFO A and coarse tuning with OFS -- no switch taps needed.

That normally isn't a problem: when you're tuning an antenna you are aiming for lowest SWR. The exact SWR isn't important as long as it is minimum.

In it I slightly facetiously coined the term "imaginary modes" for the WSJT-X suite and explained it in the footnotes copied here: "* I call them imaginary because the programs actually decode signals that aren't there (1), or use databases of callsigns as lookup tables to guess received calls (2). In a discussion I had with one of the FT8 developers about the TX delay in Elecraft radios causing transmission to be delayed until after the decode window opened, he opined that it might not matter because the decoder can "decode" signals that it never heard. (1) Quoting G4WJS: "For FT8 the net effect is that up to about 5 seconds of a message may be missing yet still be decoded. 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." (2) Another compelling paper discusses JT65 as used on EME. http://www.sm2cew.com/Digital%20communications%20using%20minimal%20transfer.pdf " ?So not to worry, your computers can continue to work each other without worrying about VOX delay.

Joe Taylor-K1JT invented all these nice new digital modes which originally were designed for ms (meteor scatter) and eme (moonbounce). Knowing ms and eme stations run QRO on VHF+ with low noise preamps, there was a need to delay the digital transmission so all the various relays and accessories were switched to transmit. Typically that was 300msec (0.3 seconds). So the sw engages PTT and waits for everything to be ready before sending audio to the transmitter. Now that "hot shot" HFers are wanting to "Hot switch" their gear a guess FT8 and WSJT-X versions have provided for user input on the delay length. Now you "know the rest of the story". Note: I use a USB/RS232 cable and key with DTR. I couple audio input and output via two RS audio cables from my external soundcard (emu0202) to my 2010 K3 (4340). I have computer generated audio turned off (no "you have mail" or internet beeps). Besides, I have a separate computer for normal internet/e-mail, etc. My dedicated ham radio computer is normally disconnected from internet and I keep computer time by use of a GPS dongle (I can restore internet for K3 fw upgrades). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From dave at nk7z.net Fri Feb 23 15:51:59 2018 From: dave at nk7z.net (Dave Cole (NK7Z)) Date: Fri, 23 Feb 2018 12:51:59 -0800 Subject: [Elecraft] K3 And WSJT-X FT8 Timing In-Reply-To: References: <0B96B19D-4A6D-47EB-8200-84A7D64897AD@comcast.net> <58e0ff14-597e-4c0a-82fa-62207b1ca225@blomand.net> <3DA46F6C-8EBA-46ED-A25D-2B5D30819673@comcast.net> <359427454.4778105.1519408722453@mail.yahoo.com> <3CC28F07-655D-418A-954B-E31DD0872484@me.com> Message-ID: What is the CPU and Memory usage in percent, under the PERFORMANCE tab of the system task manager, with WSJT-X sitting idle and listening? 73s and thanks, Dave NK7Z https://www.nk7z.net From wes_n7ws at triconet.org Fri Feb 23 15:52:00 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Fri, 23 Feb 2018 13:52:00 -0700 Subject: [Elecraft] K3 And WSJT-X FT8 Timing In-Reply-To: <201802232012.w1NKCGdd030451@mail41c28.carrierzone.com> References: <201802232012.w1NKCGdd030451@mail41c28.carrierzone.com> Message-ID: And before that we used CW.?

I counted down the 60 Hz to generate timing, either 15 sec or 2 min depending on mode.? This started the changer over sequence and the memory playback.? However, the generated CW was run through a shift register (FIFO) with a variable speed clock that determined the TX delay, allowing the various stuff to accomplish their missions. Some retriggerable one-shots held things in the correct states until the message ended and the sequence reversed. I ran an 8877 and GaAs FET preamp at the antenna and never had a failure except when I rushed to get on FM using a multimode (non-sequenced) rig to work W5LFL.?

I usually have the K3 USB coming int through another USB hub. (Note that KIO3B has in internal hub branching out to a USB Audio Codec, and a FTDI USB <--> RS232 interface. As such, all the RS232 parameters in wsjt-x are used, so it is important that they are set correctly. I did have to fiddle with the driver configuration on my MacBook, probably because I installed a FTDI driver before Apple started providing one with the system, and 2 drivers confused things. (I don't know if Windows has a similar issue, but I understand that recent releases of Windows include a FTDI driver.) I do all kinds of things with my computer, mostly downloading and reading email, while my FT8 contacts complete themselves. If you had a K3 without the KIO3B upgrade, you should be able to get wsjt-x to control the rig through the CAT interface using a USB <--> RS232 converter (brand Elecraft recommended). Really, the things you are buying with the KIO3B are fewer cables and fewer audio level adjustments. 73 Bill AE6JV On 2/23/18 at 6:16 AM, rmcgraw at blomand.net (Bob McGraw K4TAX) wrote: >?I'm not running any other applications such as JT Alert, >N1NM, etc.?

That could be an arc or the match isn?t really 1:1. Using an antenna analyzer at the balun would be useful. If you?re on 80M, without the tuner, you?re likely to see ~3:1 untuned at the balun, within the range that should almost work, BUT it also depends on the length of the open wire feed. (Using a 75 ohm feed would be wiser if used for only 80M). Try modeling it on EZ-NEC, then adjust the feed (in the model) by some feet to see what that does. If you?re using it for multiband, you?ll have to run it for each band. Getting it to work well on all bands is a serious challenge, near impossible; something has to give. It?s likely too that the model won?t show coupling or losses exactly to the real world (metal, trees, walls), so if it suggests you make changes, you?ll still have to adjust to your real antenna. In short, go play. My 340? 80M EDZ was textbook perfect (2 opposing 5/8 wave, center fed, NOT resonant) but didn?t load that way, until I added almost 30? more antenna AND shortened the feed by 50? in the real world. After more than 200 countries later (on all bands 160-10), I?d say it worked pretty well. Not easy, but I was patient. Having a K3 made the difference, often the DX did too. Good luck, it?s one of the fun things to do in ham radio. 73, Rick WA6NHC Smell Czech correction happen > On Feb 23, 2018, at 9:42 PM, Chris Hallinan wrote: > > Greetings from southwest Florida. > > My KPA500 is kicking out with REFL HI warning (high SWR).

We see more of than than we would like. There are many poor UHF connectors and (especially) adapters around. This is especially true with right angle connectors. There is another possibility that could be happening. RF loves any wire it can find for return currents. The outer braid of the 40 feet of coax could be doing a great job of picking up RF and conducting it back to the KPA500. We usually see this with vertical antennas which are very happy to use the feedline for return current, but this also could be happening with your setup. The idea is that at HF, current flows on the edge of the braid. In this case there are two edges, one inside the cable (closest to the center conductor, with the second on the other (outer) side. The current you expect is flowing on the inside, and the outer can pick up anything stray, including the signal you are trying to radiate. This is conducted back to the amplifier where it really messes up the sample signal. I would also expect you to see RFI with this setup. A third possibility comes from where you now live. As I learned long ago as a young ham in Miami, the South Florida heat is very harmful to coax cable. Over (an amazingly short) time the coax inner conductor can migrate through the insulation and come into contact with the shield. This is very common, occurs within just a few years (or months in some cases) and requires coax to be replaced every few years. It almost always occurs at bends in the coax. This, of course, leads directly to the arcing issue described above (and by others). Foam dielectric coax is probably the worst with this issue. The solution is new coax. And do your best not to bend the cable! The solution to the second issue is a good balun choke. K9YC would advise running the coax through a large toroid several times to help resolve the problem. An alternate is to use a large number of coax-size toroids fed onto the coax, which will also choke off the unwanted currents. You might want to prefer the latter because of the same migration issue described above. In this case the turns on the toroid _will_ fail within a short time. See K9YC?s excellent web page for more information. He has a very good paper on baluns, especially choke baluns. Best o flick solving this issue. That South Florida sun and heat can play havoc with ham stations. Much different problems than those seen in 1-land! 73, Jack, W6FB, ex-WA4FIB > On Feb 23, 2018, at 9:42 PM, Chris Hallinan wrote: > > Greetings from southwest Florida. > > My KPA500 is kicking out with REFL HI warning (high SWR).

Most authorities suggest a 1:1 balun with a setup like this. As you know, the impedance seen at the balun will vary all over the map, depending on the band and the length of the 600-ohm line. I've calculated that the voltage that appears at that point in my somewhat similar setup is as high as 7 kV when I'm running 1200 watts on one particular band.

Some additional information: This installation is brand new. The antenna has been up only a month or so. Tuner and Balun even less. Coax is newly run, and I've deliberately avoided sharp bends. I purchased the KPA500 in December, so all of this QRO is new for me (in this century at least!) I am running through a surge protectors from Alpha Delta. I will double check is is not the 200W versions! Hmmm, now that I think of it, maybe that's it??? Will check after coffee! Any tips on how I would detect/locate any potential arcing? I do understand the nature of the antenna and the potential wide range of impedances possible with this multi-band setup. - I'm going to scan it at the balun this morning with my AIM 4300 for starters. Oh, and check/bypass the surge protector too!

If you want to do an easy test to localize where the failure may be, you can do it with a dummy load. First put the dummy load at the rig. Check to see if all is OK, if not, blame the rig. Then check the coax - connect the dummy load at the end of your coax (replacing the remote tuner). If the problem shows up, then blame the coax. If all is still OK with the dummy load at the end of the coax, you can blame the tuner, balun or the antenna or RF getting onto the coax outer shield. Look for evidence of arcing, make sure all connections are solid - then try adding a K9YC type current mode choke near the entry point entry to the shack to choke RF coming in on the outside of the coax braid. 73, Don W3FPR On 2/24/2018 12:42 AM, Chris Hallinan wrote: > Greetings from southwest Florida. > > My KPA500 is kicking out with REFL HI warning (high SWR).

Dummy load at the end of the tuner chain-- if it works at high power then all is good from the dummy load back, the problem lies downstream of the dummy load. If it fails with the dummy load there, then you have a coax problem between the radio and the dummy load. So far you have done a bit of triaging already, if you operate on the vertical, with no tuner, and all is good, then you know the radio and amp are OK. You also know the feed line to whatever type of coax switch you have is OK... Move the dummy load around to triage out as much as possible... If you don't have a dummy load, you need one... Every station needs a dummy load just for this sort of testing. 73s and thanks, Dave NK7Z https://www.nk7z.net > On 2/24/2018 12:42 AM, Chris Hallinan wrote: >> Greetings from southwest Florida. >> >> My KPA500 is kicking out with REFL HI warning (high SWR).?

On MFJ's "Mobile" tuner I had to bend the adjacent turns away from the soldered taps (by pushing each adjacent quarter turn into the coil's interior, which is standard practice for these air inductors) in order to get it to work right.

That was the case for my 370' 80M EDZ (two opposing 5/8 wave, center fed).? That is specifically a non-resonant antenna on any ham band but it performed best with the 4:1 instead of the 1:1.? It was a compromise either way, this was the better choice since I needed that antenna to work on all bands.? If it was only 80M, the 1:1 was the better choice. While I am not a fan of MFJ so consider it suspect in this case, I also believe that since the common mode choke (referred to as a balun in this thread) should GREATLY exceed the voltage expectations for simple overhead.? The cost differences for higher ratings are not significant.? In my stations, I use the 10KW rated devices from DX Engineering (KPA500 amp) and I've had no issues with them, even at extreme SWR mismatch (QRO on 160M into the above dipole, 20:1 unmatched with a Heathkit tuner).? My new station will be entirely resonant, so a 1:1 CMC will suffice but I'll still use the high power devices. The bottom line here is that the antenna in this thread is not resonant (because of the feed choice, which is understandable for multiband use), the voltages presented will be extreme, component overkill (and a more qualified tuner) should be used.? It's not a fault of the amp, but of the matching network. It is also KEY that the LEAST amount of coax is used (under 10' to the final) because the high SWR is present there as well, so the losses will be extreme and it could even exceed the voltage limits of the coax, depending on brand, age and type.? Been there, done that (darned HOA limits).? This also means that the coax should be tested, from time to time, until proven worthy.

Any in-the-shack pre-amp ahead of the K3's 2M transverter is a waste of time. Unless of course, you just want to see your S-meter read higher and don't care that you've completely destroyed the dynamic range of the system. The best way to improve on this is by installing a mast-mounted pre-amp which will over-come the inevitable feed-line loss. As stated, the 2nd best way is to use a lower loss feed-line, but unless you're now using RG-58, the low-loss stuff might be more expensive than the remote pre-amp depending on the length you need. 73, Charlie k3ICH -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Peter Torry via Elecraft Sent: Saturday, February 24, 2018 12:45 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Adding a low noise preamp into the receive line of the internal 2M trnsverter Howard, Adding an internal preamp is not a trivial task as it would mean some surgery on the transverter board.

The higher the swr, the higher the max voltage, for a given power level. So, the manufacturer of the protective device should probably not just tell you a wattage rating, but also the acceptable swr level for that power. The higher swr level that is acceptable, the less protection is provided for your rig and tuner, etc. My guess would be that those protectors are meant for use at low swr. A multiband dipole fed with ladder line + balun + coax will have high swr on the coax at least on some bands, regardless of whether it is 1:1 or 4:1 or whatever. I would not expect the impedance to be close to 50 ohms on the coax. You might want to forget about the protection. Or, build a spark gap protector to be located on the ladder line. Or abandon the ladder+balun+coax approach and go to an end-fed dipole with transformer that can provide low impedance coax feed on all bands. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Rick WA6NHC Sent: Saturday, February 24, 2018 10:41 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 faulting on high VSWR on power rise One exception is when the dipole is used on multiple bands, then a 4:1 may be required. That was the case for my 370' 80M EDZ (two opposing 5/8 wave, center fed). That is specifically a non-resonant antenna on any ham band but it performed best with the 4:1 instead of the 1:1. It was a compromise either way, this was the better choice since I needed that antenna to work on all bands. If it was only 80M, the 1:1 was the better choice. While I am not a fan of MFJ so consider it suspect in this case, I also believe that since the common mode choke (referred to as a balun in this thread) should GREATLY exceed the voltage expectations for simple overhead. The cost differences for higher ratings are not significant. In my stations, I use the 10KW rated devices from DX Engineering (KPA500 amp) and I've had no issues with them, even at extreme SWR mismatch (QRO on 160M into the above dipole, 20:1 unmatched with a Heathkit tuner). My new station will be entirely resonant, so a 1:1 CMC will suffice but I'll still use the high power devices. The bottom line here is that the antenna in this thread is not resonant (because of the feed choice, which is understandable for multiband use), the voltages presented will be extreme, component overkill (and a more qualified tuner) should be used. It's not a fault of the amp, but of the matching network. It is also KEY that the LEAST amount of coax is used (under 10' to the final) because the high SWR is present there as well, so the losses will be extreme and it could even exceed the voltage limits of the coax, depending on brand, age and type. Been there, done that (darned HOA limits). This also means that the coax should be tested, from time to time, until proven worthy.

Actual ratings at other loads can be inferred on that basis. An end fed dipole is MUCH harder to tame than a dipole (or fan dipole) and inherently challenging to keep the RF away from places like the shack.

Message-ID: <20128430.37282.1519508554015.JavaMail.defaultUser@defaultHost> I have a P3 with latest revision of firmware and an SVGA card and a station monitor and a USB keyboard plugged in as well. The frequency readout on the P3 and external monitor is correct under all common operating situation when I have a ?span? of, say 100KHz. However, when I use the command sequence:- #CTF00000000000;#SPN00040;RCF+002000 which gives a span of 4KHz, centres the frequency and then effectively moves the filter area to the left there is a small problem. If I set the dial to 7.100KHz then apply the above command string (via a stored macro accessed via the USB keyboard) then the reading on BOTH the SVGA connected monitor and the P3 itself stow 7.100.0 at the left 7.100.00 middle and 7.104 at the right edge. Clearly this is not correct. Thoughts and observations welcomed.

Such antennas should not behave much differently compared to end-fed verticals such as the R5 that I have had for many years and which creates no problems even at high power. Like that antenna, the wire models now becoming popular use a high ratio wide-band impedance transformer. The R5 also includes tiny radials and a common mode choke at the feedpoint. The R5 behaves well even at high power with its feedline length of maybe 50ft, and there is not enough RF in the shack to affect the operation of radios or other equipment. However, for good measure I added a second common mode choke in the form of several ferrite snap-on's about 10 ft from the feedpoint and then found a noticeable reduction in shack RF (measured in the shack using an MFJ RF current sensor). I believe there are lots of satisfied users of the Cushcraft endfed verticals. As to the wire end-fed's I am constructing an imitation of a popular commercial version, and will find out for myself if there are any difficulties. I will add a common mode choke placed either at the feed point (like the R5) and a separate counterpoise, or I might try placing the choke a distance away from the feedpoint to let a portion of the feedline act as counterpoise. Again, a second common mode choke further down the feedline will likely be added. Based on the positive reports by so many users of the commercial versions, who apparently don't add any common-mode chokes, I am fairly confident of success. 73, Erik K7TV -----Original Message----- From: Rick Bates (WA6NHC) [mailto:wa6nhc at gmail.com] Sent: Saturday, February 24, 2018 1:35 PM To: Erik Basilier Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 faulting on high VSWR on power rise I?ve always presumed that the ratings were based on 1:1 SWR as there is no reasonable way to define it otherwise.

I was able to find more usable bands with the 4:1 (meaning closer matches). If the dipole is single band only, using a 75 ohm feed (choke at the transition from feed to antenna) is best. A resonant dipole is closer to 72 ohms, ignoring local conditions, one of which is elevation above ground. Inverted vee systems are lower impedance so 50 ohm is the proper choice (again, single band only). For this example of multiband use AND open wire feed (for dramatically lower feed loss at high SWR) which alters the impedance of the system and the length of the feed matters; one can use an analyzer to find which transformer works best or simply try both. The 4:1 presents a bit more device loss compared to a 1:1, but if it also provides near resonance on more bands, so that loss is negligible. With open line (75-600 ohm typical) you don?t match the line with the balun, you match what the SYSTEM presents, antenna and feed.

Unless it is a resonant antenna, the impedance is not purely resistive, usually far from it. It can be almost anything. The feedline length will affect what the impedance is at the tuner. The tuner, if you have one, will select, or you will select the configuration and values of inductance and capacitance that provide the correct match. Those components, especially the inductors have losses and heat up. You don't generally know what those losses are and they vary from part to part. The tuner It can often match with a 1:1, 4:1 and other baluns, as long as the impedance seen by the tuner is within it's range. The claims that a tuner can tune 10:1 or 3:1 are not that useful, except for a general comparison. They can't match every possible impedance, inductive, capacitive or whatever within that range. Depending on the manufacturer's choices of values, they may be able to match a higher SWR if it is very inductive, rather than capacitive, for example. The optimal match will also be determined by the losses. You may be able to get a match, but 50% of your power may be absorbed by the tuner, with smoke eventually being let out. I use a homebrewed dual core switchable 4:1 / 1:1 currrent balun. Most of the time, the tuner can match my Horizontal loop with the switch in either position. It may result in a lower SWR in one position or the other and I usually choose the position that results in the lowest SWR after the tuner matches. In a few cases, after transmitting for a while, the tuner will try to retune. I believe that is likely due to an inductor heating up in the tuner and changing value. That tells me the losses are likely high and I try the other switch position and see if it stays tuned. If you know what impedance your antenna system and feedline present to the tuner, you may be able to choose an optimal balun. In my case, with so many bands, there is no single best choice. I choose whatever works best on that particular frequency. 73, Mark W7MLG On Sat, Feb 24, 2018 at 8:30 PM, Bob McGraw K4TAX wrote: > I question the 4:1 balun being the correct nor best choice.

It and a 80M dipole are my current antennas, until I plant a tower later this year (55' US Tower, motor drive, tilt over).? I have to admit that I'm not a fan of vertical antennas. Since I moved here last year and haven't gotten the tower up yet, the R7 is 'adequate' for a temporary antenna, but dipoles are more effective.? It also provides decent diversity reception with a horizontal dipole.? (The new antenna, when it gets up, is a SteppIR DB-42 at 60', resonant 80-6M then I'll add in a Beverage for RX only since I have the space now or a K9AY.? I have a 160M inverted L up too (bend at about 90'), using the underground water pipe as the counterpoise, buried down 4-5', 1:1 CMC at the base, it was quick and simple.? I'm adding a tuning network to that so that will be a 80/160M resonant vertical, giving me another option on 80M.)? The beautiful part is that with only 2 resonant antennas, I can cover 160-6M once I'm done, perfectly matching the new KPA1500.? Simple ROCKS! The R7 (like the R5, 8, 9) has a matching network (torroids mostly) in the black box and trap and capacitive elements on the main element and short radials at the base to get it to load, but that doesn't meant that it's efficient; it means it presents a load that is acceptable (so does a dummy load).? The EDZ at my last QTH beat? the R7 in almost all scenarios on any band, unless the other station was off the ends of the dipole, then it was even money; which left the R7 being used for diversity. So it works, but I wouldn't rate it highly unless one is limited by space, HOA or similar.? It reacts badly when near (w/in 10' of) any metal and the base must be at least 10' AGL.? Adding more choking is very wise.? I would expect similar results from a non-commercial antenna, unless used only on one band (and it's still a challenge to tame).

Such antennas should not behave much differently compared to end-fed verticals such as the R5 that I have had for many years and which creates no problems even at high power. Like that antenna, the wire models now becoming popular use a high ratio wide-band impedance transformer. The R5 also includes tiny radials and a common mode choke at the feedpoint. The R5 behaves well even at high power with its feedline length of maybe 50ft, and there is not enough RF in the shack to affect the operation of radios or other equipment. However, for good measure I added a second common mode choke in the form of several ferrite snap-on's about 10 ft from the feedpoint and then found a noticeable reduction in shack RF (measured in the shack using an MFJ RF current sensor). I believe there are lots of satisfied users of the Cushcraft endfed verticals. As to the wire end-fed's I am constructing an imitation of a popular commercial version, and will find out for myself if there are any difficulties. I will add a common mode choke placed either at the feed point (like the R5) and a separate counterpoise, or I might try placing the choke a distance away from the feedpoint to let a portion of the feedline act as counterpoise. Again, a second common mode choke further down the feedline will likely be added. Based on the positive reports by so many users of the commercial versions, who apparently don't add any common-mode chokes, I am fairly confident of success. > > 73, > Erik K7TV > > From nr4c at widomaker.com Sun Feb 25 01:35:55 2018 From: nr4c at widomaker.com (Nr4c) Date: Sun, 25 Feb 2018 01:35:55 -0500 Subject: [Elecraft] K3 Configuration Listing?

Certainly I rarely use mine as I get much better results with my horizontal beam (Sommer XP708). My comments regarding the R5 were meant to be only about issues with matching and rf in the shack etc. I agree that reality isn't always in agreement with the theories at hand. That is why I plan to compare the end-fed with a center-fed before I commit to it for personal use. In a previous thread I have outlined my planned comparison, "side by side", trying my darnedest to notice any performance loss resulting from the endfeed. We shall see about that. I won't take up space here to repeat all the discussion about that testing. What I have tried to say in this thread, is that I am rather confident that I can "tame" the end-fed in the sense that it won't cause problems with rf in the shack, and regarding performance I will assume there is no problem until my comparison shows that there is. The original poster had a problem with coaxial protection devices, and if I understood his configuration correctly, such problems could be anticipated in that configuration. I pointed to end-feed with tunerless low swr as a potential approach to make those protection devices work as intended, with a radiator that is the same length wire as what he had. Your antenna farm is a separate subject, as is mine, and in this thread I will just comment briefly on those subjects. I got interested in SO2R, but don't have space for two towers/beams. You may not be thinking about SO2R, but if you are, and if you too can't put up a second tower/beam, then you might want to think twice about using SteppIR. With a beam that can work multiple bands without retuning, I use a multiplexer that allows two transmitters to use the same beam as if I had two separate ones. (Minus the capability to point them in different directions!). If an end-fed wire antenna works well without tuner on multiple bands, it can also be used with a multiplexer to perform instantly on another band, without retuning. Not so with a simple center-fed dipole (but a fan or trapped dipole would be ok). My other comment is about your verticals fed against a pipe in the ground. When I was using inverted L's for 160 and 80, I first tried them against a single, 4" wide copper strap going part way around the house and tied to a few ground rods here and there. Then I tried it against two zigging wires used as elevated radials. This worked much much better. Like others have said so often and so well: If you are going to bury radials, it will take many of them. 73, Erik K7TV -----Original Message----- From: Rick WA6NHC [mailto:wa6nhc at gmail.com] Sent: Saturday, February 24, 2018 10:30 PM To: Erik Basilier Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 faulting on high VSWR on power rise I have an R7 (end fed vertical 40-10M). It and a 80M dipole are my current antennas, until I plant a tower later this year (55' US Tower, motor drive, tilt over). I have to admit that I'm not a fan of vertical antennas. Since I moved here last year and haven't gotten the tower up yet, the R7 is 'adequate' for a temporary antenna, but dipoles are more effective. It also provides decent diversity reception with a horizontal dipole. (The new antenna, when it gets up, is a SteppIR DB-42 at 60', resonant 80-6M then I'll add in a Beverage for RX only since I have the space now or a K9AY. I have a 160M inverted L up too (bend at about 90'), using the underground water pipe as the counterpoise, buried down 4-5', 1:1 CMC at the base, it was quick and simple. I'm adding a tuning network to that so that will be a 80/160M resonant vertical, giving me another option on 80M.) The beautiful part is that with only 2 resonant antennas, I can cover 160-6M once I'm done, perfectly matching the new KPA1500. Simple ROCKS! The R7 (like the R5, 8, 9) has a matching network (torroids mostly) in the black box and trap and capacitive elements on the main element and short radials at the base to get it to load, but that doesn't meant that it's efficient; it means it presents a load that is acceptable (so does a dummy load). The EDZ at my last QTH beat the R7 in almost all scenarios on any band, unless the other station was off the ends of the dipole, then it was even money; which left the R7 being used for diversity. So it works, but I wouldn't rate it highly unless one is limited by space, HOA or similar. It reacts badly when near (w/in 10' of) any metal and the base must be at least 10' AGL. Adding more choking is very wise. I would expect similar results from a non-commercial antenna, unless used only on one band (and it's still a challenge to tame). Dipoles are much simpler, even when used for multiband operations. Cut the antenna to the desired (available) length, add the feedline, measure, adjust for local conditions (add/cut feedline for open wire or antenna for single band) then see how it plays.

The water pipe (300+' in two directions, deep enough to never freeze) is the L counterpoise, for now.? It isn't ideal but it works and isn't meant for forever. I will be installing a lightning protection and counterpoise system with lots of copper, ground rods etc, which will come to box (for feed line, rotor control) at the tower end of the conduit to the shack (AND tie into the house grounding per code).? The box will have hardline from the house, coax for the tower, matching network for the Inverted L and the surge and lightning devices on each feed (static or lightning stays OUTside).? I'll also put an AC power outlet at the base, for occasional power tool use and a wifi web cam (may as well, I have to power the electric winch motor). I DX, I don't contest, so I don't need SO2R (other than the second rx for DX chasing on splits).? Should that someday change, I'm blessed with the space for a tower farm or I'll put the EDZ up (kind of a favorite, I worked a LOT of DX on that dipole).? With the KAT500 (or KPA1500), rapid QSY isn't an issue on the EDZ. No slam was inferred or taken on the Cushcraft; only that the compromises add up to make it work, but not as well as a tuned dipole. I'm not sure that an end fed wire antenna will work well on multiple bands without a fair amount of effort (remote tuner at least, absolutely a CMC to back that up).? The voltages at radical SWR (non-resonant afterall) can be high.? Isolating the radiation to the wire is a major issue, that antenna tends to want the feedline (coax commonly) as the counterpoise, bringing RF into the shack (and why I went with the inverted L which partly warms the worms). 73, Rick NHC On 2/24/2018 10:53 PM, Erik Basilier wrote: > Your antenna farm is a separate subject, as is mine, and in this thread I will just comment briefly on those subjects.

I have not been using it very much - just a few FM QSOs. I have not seen any problems. Now I have just started using K144XV on digital modes - especially FT8 (42% TX and 58% RX).

But without regard to the starting point I could get normal output again just by changing the output a little bit. It did not matter whether I increased or decreased my power a bit. I did not hear any fans starting up and I could not feel any heating at any sides of the K3. Can anyone explain what is going on - what I am doing wrong - what I can do to keep the output stable?

Yes, K3 Utility polls the K3 for each data element that is stored. If you want to "roll your own" version to save specific data, you can do that - look at the K3 Programmer's Reference (download from Elecraft) to see the commands needed to accomplish that feat. The data is not a fixed K3 file, but depends on the individual K3. For one thing, it contains your current menu settings and other information unique to you particular K3.

To me, moving a dipole's feed from center to the end (or to somewhere in between) doesn't change its radiating characteristic as a dipole. Whether the feed method is free of loss, or free of diverting power off of the dipole are complicated questions better answered by serious testing of an individual design than by simple rules of thumb. I haven't recently looked into the "box" of my Cushcraft vertical, but it has been reported that there is a separate impedance transformer and a separate common mode choke. A very low swr is achieved without a tuner, at full legal power (within bandwidth limitations; people have blown up toroids when going outside bandwidth on 40m on the R7). There is obviously not a high level of power lost in the "box", or it would not survive full legal power. Thus this is not like some antennas that sacrifice efficiency by swamping in order to achieve low swr. Therefore most of any observed loss of performance can be attributed to the radiator and its environment, in combination with some rf going on the outside of the feedline (which is not completely prevented by the one CMC in the box). Some end-fed antennas use a non-resonant radiatior. This invariably results in swr high enough to require a tuner. Since the R5/R7 has low swr and not very high losses in the "box", the radiator obviously is resonant on all bands, presenting a non-reactive impedance at the end. That impedance must be very high since it is at the end. The very high non-reactive impedance makes it comparable to the end impedance of a resonant halfwave wire dipole even if the Cushcraft radiator is in other respects different. That is my basis for assuming that the Cushcraft "box" can be compared to what you would put at the end of a wire dipole when moving the feed from its center to one end. An end-fed dipole can be resonant and present a very high but non-reactive impedance on multiple (higher) bands. This can allow a fixed, broad-band impedance transformer to provide low swr on multiple bands without a tuner. Yes, one has to be suspicious of possible losses in the transformer, and it takes a fight to stop rf from going onto the outside of the feedline. But since one avoids swr-caused losses in coax, and balun losses, and tuner losses with end-feed, I consider it an alternative worthy of serious consideration. If optimal protection against high voltages on the coax is a main goal, that just might tip the scale to make the end-fed dipole the winner. 73, Erik K7TV -----Original Message----- From: Rick WA6NHC [mailto:wa6nhc at gmail.com] Sent: Sunday, February 25, 2018 2:52 AM To: Erik Basilier Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 faulting on high VSWR on power rise Hi Erik, I'll keep this short as the thread will likely be closed soon (or should). What I have up now is Field Day style, simple antennas (the inverted L for example, an 80M dipole, R7) shot into the trees so I could get on, pending the install of 'the real station', hi. The water pipe (300+' in two directions, deep enough to never freeze) is the L counterpoise, for now. It isn't ideal but it works and isn't meant for forever. I will be installing a lightning protection and counterpoise system with lots of copper, ground rods etc, which will come to box (for feed line, rotor control) at the tower end of the conduit to the shack (AND tie into the house grounding per code). The box will have hardline from the house, coax for the tower, matching network for the Inverted L and the surge and lightning devices on each feed (static or lightning stays OUTside). I'll also put an AC power outlet at the base, for occasional power tool use and a wifi web cam (may as well, I have to power the electric winch motor). I DX, I don't contest, so I don't need SO2R (other than the second rx for DX chasing on splits). Should that someday change, I'm blessed with the space for a tower farm or I'll put the EDZ up (kind of a favorite, I worked a LOT of DX on that dipole). With the KAT500 (or KPA1500), rapid QSY isn't an issue on the EDZ. No slam was inferred or taken on the Cushcraft; only that the compromises add up to make it work, but not as well as a tuned dipole. I'm not sure that an end fed wire antenna will work well on multiple bands without a fair amount of effort (remote tuner at least, absolutely a CMC to back that up). The voltages at radical SWR (non-resonant afterall) can be high. Isolating the radiation to the wire is a major issue, that antenna tends to want the feedline (coax commonly) as the counterpoise, bringing RF into the shack (and why I went with the inverted L which partly warms the worms). 73, Rick NHC From kq5stom at gmail.com Sun Feb 25 10:02:21 2018 From: kq5stom at gmail.com (Tom-KQ5S) Date: Sun, 25 Feb 2018 09:02:21 -0600 Subject: [Elecraft] K3S Memories In-Reply-To: References: Message-ID: Thanks to Dan, N3ND, the answer was in the help files for the program.

If he cannot easily remove the two boxes from the larger one because it is a tight fit, it is easy to bend one flap down and roll the box over that flap and over again so the box is sitting on its open end. Then it is easy to lift the outer box off with no struggle. The way the gear is packaged, it will survive that "rolling over" with no harm at all. I do that regularly at trade shows for the K3, and more recently the KPA1500 because it is difficult to lift the units vertically out of the box due to the tight fit and the resistance of the foam shipping material to the sides of the box. Much easier to roll it over and lift off the box. 73, Don W3FPR On 2/25/2018 3:53 AM, G4GNX wrote: > > What Bill wants is two SEPARATE boxes to be shipped to him, without an > outer wrapper to combine them.

Both KB7Q and I have observed this behavior after carefully setting up our K3s for WSJT-X operation with the K144XV. KB7Q found if he ran JT65 in USB mode the power setting behavior of the K144XV was normal but if he ran in DATA A mode it was anomalous. I have had the exact same problem while running MSK144 in DATA A mode. Both of us observed the same ?cure? as Kjeld: slight movement of the power control restored normal power output. Neither of us had this problem while running SSB or CW. The two K3 transceivers we made these observations on were SN 7xx and SN 4611, which are widely spaced in date of production and board revision levels. When KB7Q upgraded to a K3S, using the same K144XV module, the anomalous power setting behavior in DATA A mode did not occur. I have a very strong suspicion that this problem is related to the new firmware that is shared by both the K3 and K3S. It works correctly in the latter case but not the former. Unfortunately I cannot revert to a pre-K3S firmware version. 73 Gary, N7IR -------------------------------------------------------------------------------- Kjeld, Are you driving the audio up to 4 bars on the ALC meter with the 5th bar flashing?

Message-ID: On my recently acquired K3s (MCU 05.62, FPF 01.26, DSP1 02.88, DSP2 N?A, DVR N/A), Serial number 11501, I have notice a USB audio anomaly that I do not understand nor can I find described in the manual. If you monitor the USB audio output port on the attached computer you will hear, or see on the audio display of a scope application, fldigi waterfall or monitor speaker any audio that is being used to modulate the transmitter. The transmitter can even be in the TEST mode where no actual output occurs. This ?looped back? audio is unaffected by the MON function and does not vary in amplitude with MON set anywhere from 0 to maximum value. It does not matter if the source of the audio is the FP mic, RP mic or Line In audio source. The audio is looped back to the USB output port at a constant amplitude. This occurs when the LIN OUT configuration option is set to NOR and at any amplitude. Only when the LIN OUT option is set to PHONES is the loopback path broken and the MON function performs as expected with the looped back level changing from OFF (MON = 0) to a varying level as the MON level is increased from 1 to 60. When using either Speakers, Headphones or both all actions are normal and as described in the manual. It is only when you monitor the USB output toward the attached computer (Mac or Windows) that you become aware of this loopback path. I believe it is a BUG but if it is a feature I would appreciate knowing where it would be beneficial.

Please indulge me in one more effort. All this recent talk about K-2?s makes me homesick for the one I built shortly before my retirement (Serial #5529). I spent an entire summer carefully following the instructions and created an astonishing radio. Sometime after that, the lure of the K-3 took over and I sold my K2 to finance the purchase of the K-3. I now regret that decision. If anyone out there knows who has my old K-2 please contact me off-list. I?d like to discuss reacquiring the radio.

When I needed to move the power supplies for my Ten Tec Titan amps, I slid them from the shelf under my operating desk onto a rolling chair. I can't even lift, let alone carry, the 87As that are on my operating desk. I got help from a neighbor ham carrying them in. Perhaps that might be a solution for others. 73, Jim K9YC On 2/25/2018 12:53 AM, G4GNX wrote: > What Bill wants is two SEPARATE boxes to be shipped to him, without an > outer wrapper to combine them.

You and Eric are too kind. Sadly, the years have taken their toll on my ambitious youth. I?m less patient these days, and far from as steady of hand as I was then. Perhaps my efforts to reunite with my K2 are a last gasp to hold on to my memories of a 16 year old kid with a new novice license. Wow! That?s lot of baggage to heap on a lowly K2. Maybe fate will lead me to the radio. Anyway, I couldn?t build a new one now, even if you threw a KPA1500 into the deal. BUT, if I do find the radio, how about I bring it to Dayton and collect those signatures. The Dayton booth is where I bought my lost K-2. And if experience is any guide, I?ll buy a KX2 while I?m there. Thanks for being a friend to me and all of us Elecraft enthusiasts.

Later this year, I want to make several enhancements, including the replacement of the KPA500 and KAT500 with a KPA1500. The amp/tuner should be a fairly straightforward hardware replacement, but it does necessitate a few station changes which I?m not certain how to implement. Let me explain and hopefully the masses have ideas/approaches for consideration. 1. I feed a HyTower vertical (optimized for 40M & 80M) on all bands. Where the driving impedance is close to 50 ohms on 40M & 80 (my bands of interest) there has been no attempt to match the HyTower on other bands. With the KAT500, matching was not a problem and I reduced mismatch losses on the feed line by using hardline from the in-shack tuner to the antenna. When I switch to the KPA1500, operation on the unmatched bands might prove problematic. To address this, I plan to provide switchable matching networks to transform the HyTower drive impedance on each band to something the KPA1500 can match. I can design the required impedance transformation networks, but not sure how to automatically select the various (relay based) impedance networks required for each band. Clearly, I need to grab band data from the K3, but what?s the best hardware to use for this task? BTW, I want to power the KPA1500 ON with the K3, which requires a Y-cable modification, or perhaps one of the N6TV boxes? 2. I want to interface a K9AY RX antenna 4 position switch to some sort of UI that I can access remotely. I can design an electrical interface to the K9AY switch, but controlling and monitoring remotely is the issue. Ideas? 3. I have a Windows computer available at each end of the radio circuit. The only other hardware is a SignalLink used for digital mods. 4. Configuring the station for future antenna enhancements (e.g. SteppIR if we live long enough to see sunspots return!) are great if they come without significant reliability impacts. Any ideas how to accomplish the required switching/monitoring?

It includes a tuner, and I would expect it to be capable. I have been using Arduinos to control things, as they have lots of I/O and appear to the computer as a USB serial port. Those serial ports can be remoted via software, although I have not done it. I write simple software that takes commands over the USB serial port and replies with a response. See an example at https://sites.google.com/site/spectrumlabtesting/home/usb-controlled-rf-switch Maybe you can modify it to control something else. There are Arduinos with multiple serial ports and lots more I/O that may be useful too. If you have not tried it, programming an Arduino is not that hard and there are plenty of examples out there to do almost anything you can think of. I can't help much with the other stuff, as I have a KPA500 but none of the other stuff you listed. 73, Mark W7MLG On Sun, Feb 25, 2018 at 2:50 PM, Dennis Ashworth wrote: > I?ve been remoting my K3, KPA500, KAT500 station via the RemoteRig boxes > and K3/0 mini for two years with solid results.

John KK9A From: K4TAX Date: Sat Feb 24 19:46:55 EST 2018 Based on the specification of 500 volts peak, 5KW at 50 ohms = 500 volts. It would seem the PL-259 is adequate for ham radio applications per specification to 0.3 GHZ or 300 MHz without issues. Of course one is dealing with 50 ohms, which implies essentially a 1:1 SWR. 73 Bob, K4TAX From radiok4ia at gmail.com Sun Feb 25 18:44:23 2018 From: radiok4ia at gmail.com (Buck) Date: Sun, 25 Feb 2018 18:44:23 -0500 Subject: [Elecraft] [K3] low audio volume and low s meter readings In-Reply-To: <986265306.5278192.1519600366073@mail.yahoo.com> References: <986265306.5278192.1519600366073.ref@mail.yahoo.com> <986265306.5278192.1519600366073@mail.yahoo.com> Message-ID: Try running the Rx Gain calibration routine in the K3 Utility? k4ia, Buck K3# 101 Honor Roll 8B DXCC EasyWayHamBooks.com On 2/25/2018 6:12 PM, Gary Slagel via Elecraft wrote: > I took my k3 to Belize for ARRL DX CW and pre contest worked a few contacts all of which told me I had a great signal while I could barely hear them.?

Please consider that this ham's problem with the Alpha-Delta protector may be simply that the gas-discharge device in the protector has absorbed enough energy (both from lightning and from RF) that its rating is no longer the same as a new one. Those devices do degrade after a number of "events"- That is the reason why Alpha-Delta gas discharge devices are replaceable - they do not last forever.

If you look at the K3 (or K3s...the same) the Band Data outputs are open collector pulled up by 2.2K in series with 200ohms. I knew this could be a problem with anything which wasn't properly buffered so I looked at the BCD14 schematic. I found the BCD-14 online schematic differed from the unit I had after inspection with a ohm meter and magnifying glass. I probed my unit and found the optoisolators on my board had a current transfer ratio insufficient to drive the decode chip input to a proper logic low level when used with its supplied collector resistor and driven by the K3s' modest pull up. After some discussion with the supplier I changed the collector resistors to 33K and it works perfectly now. The dark current on the optoisolator and the input bias current on the decoder are insignificant making this resistor change possible. The improper logic levels on the board could easily result in operating in the linear zone and oscillate as a result.

The original K3 did not have pullup resistors on the band data lines (correct by engineering practices, the pullup resistors should be in the receiving device). BUT as a concession to those band decoders did not implement pullup resistors in their decoders, Elecraft got a lot of "flack" because the K3 did not work with those decoders. As a result Elecraft added pullup resistors in the K3. However those pullup resistors only work with devices which will respond to the +5 volt high level. There are some band decoders that DO provide pullup resistors, and some of them tie the pullup resistors to +12 volts. Those band decoders will not work with the K3/K3S unless the pullup resistors in the band decoders are removed AND that the band decoder will respond to a +5 volt level for the logic high. The result is that the K3 and band decoder "fight" for the logic high level. IMHO, the original K3 design "did it right", and the problem lies with the band decoders. The K3 addition of the internal pullup resistors caused problems with all except those band decoders that did not have internal pullup resistors. 73, Don W3FPR On 2/25/2018 9:08 PM, John Nogatch wrote: > I had difficulty with the Unified Microsystems BCD-14, i.e. the CMOS > inverter IC was overheating. > > I eventually received the following advice from AB3CV, which I found to work. > > -John AC6SL > > > From: Jim Miller > Date: Sat, Dec 26, 2015 at 7:06 PM > Subject: Re: [Elecraft] K3 and Band Data > To: John Nogatch > > > My BCD14 purchased this summer was unreliable as well.

Often, when I?m trying to work a weak DX station, I?ll switch the sub receiver off and on, so I can better hear the DX station, then to try and hunt for the station he?s working. Lately, after switching a few times, the sub receiver audio will go dead. Changing the sub receiver volume makes no difference, it?s just not there. Once it does this, switching the sub receiver off and on does nothing. The audio does not come back until I power off the K3 and power it back on. Any one else experience this?

There are three ways to access them remotely: 1. Run them on a Windows machine at the radio site and access them via a remote desktop app such as Chrome Remote Desktop which runs natively on either Windows or Mac. The Windows machine at the radio site can be very inexpensive and, since it isn't used for general computing, can be very reliable. I do this sometimes and it works fine. My Windows server is an Intel NUC that's sized about 4"x4"x2". You can find cheaper, though. 2. Run them as server apps on a Windows machine at the radio site and access them from a Windows machine running the same apps as clients. I do this most of the time and it works great. I do it from both a "real" Windows machine and from a virtual Windows machine running under VMware Fusion on a MacBook Pro. But beware that, although Fusion on the Mac can be made to work, it's a complex environment. I needed three professionals to help me get it working, including two on the Fusion team at VMware! (It was my son, who doesn't work at VMware, who finally figured out a fatal trackpad driver problem.) 3. Run them on a local Windows machine or virtual Windows OS at the control site with remote serial ports at the radio site. This is the minimal hardware solution but it does require Fusion with the same caveat as above. Remote control is a lot of fun if you can enjoy or at least tolerate the system integration! 73, /Rick N6XI Rick Tavan Truckee, CA On Fri, Feb 23, 2018 at 9:58 AM, Chris Hallinan wrote: > Any solutions for MAC out there? > > http://www.elecraft.com/k2_remote.htm#k3remote > > I use MacLoggerDX for logging and basic rig parameter feedback for the log > and I love it.

But I don't have any desire to run the Windows OS. And worse, there are known issues running hardware devices like multiple USB serial ports using a Virtual Machine. I want to use my MACs natively. MacLoggerDX is excellent for anyone who hasn't looked lately. And the support is awesome. Heck, I'd port the utilities to OS X myself if I could get access to the source code.

Not quite. First, for at least 40 years, RG-numbers are NOT a specification, but only a generic description of cable, mostly telling us the approximate outer diameter and the characteristic impedance (Zo). Below about 500 MHz, loss in coax is all due to I squared R, which depends entirely on the combined resistance of the center conductor and the shield at the frequency of interest. Zo depends on conductor diameters, spacing, and the dielectric material. Coax with a foam dielectric allow the center conductor to be larger for the same shield diameter. THAT'S why foam cables have lower loss, NOT because of lower loss in the dielectric -- dielectric loss doesn't show up until we're well into the UHF region. Shield resistance is reduced by a larger diameter for two reasons -- more copper and skin effect. Many coax cables don't use copper for center or shield or both. Loss will be greater at low frequencies if the center is copper-coated steel, which is often done for both cost and physical strength. Loss will also be greater if the shield uses less copper or is made from aluminum. As usual, Frank has asked the right questions -- there are important "applications-related" differences between coax types, even from the same manufacturer. In general, it's best to use bigger coax from a trusted manufacturer, and with the best quality shield. Larger coax has less loss. Don't buy smaller coax because you're running low power -- our Field Day team runs QRP, and all of our coax is RG8-size with a foam dielectric for low loss and a robust copper braid shield!

Hi Tom. I don't know enough about this issue to say anything useful, except for this.? When N6RZ died something like 8 years ago, I bought a lot of his stuff and helped his XYL, Kerry, get rid of the rest of it. He had a lot of coax and some hard line; I bought the hard line, and took the random lengths of coax to an NCCC meeting, telling members where it had come from. Almost all of it was good quality stuff, some used inside, some outside. I even found some stored in a shed. I'd guess most of it was at least 20 years old. Everyone turned their noses up at it, so I brought it home, made stubs out of it, and measured their effectiveness. I didn't have a VNA then, so I used an HP generator and HP spectrum analyzer (as an RF voltmeter), doing point by point measurements. Most of the stub data in that Q&A are for that cable. Since a harmonic stub depends on a low value of impedance to work, that tells me the cables were still quite good. The only bad piece of cable I found was one whose interior jacket was green from oxidation of the shield. I think it had come from that shed. Until I learn more about it, I go under the assumption that the primary hazard is moisture.? Because dielectric loss doesn't kick in until at least UHF, I don't buy that being as a factor at HF. A few years ago, I noticed moisture around the Polyphaser for one of my high dipoles when I removed it for some reason. I had only recently replaced the dipole and the coax run (Belden 8213), but hadn't done a good enough job of sealing the coax around the center insulator. Water penetrated, came down between the braid and dielectric, and in less than a year, had turned the shield black. I put that length of coax on the VNA and found that loss had increased from about 0.4 dB to about 0.45 dB. I'm copying this to the reflector, hoping that guys like W3LPL will jump in with more. 73, Jim > > Thanks > > Tom W2SC > > -----Original Message----- > From: elecraft-bounces at mailman.qth.net > [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown > Sent: Monday, February 26, 2018 10:11 AM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] RG-8X > > On 2/26/2018 9:28 AM, john at kk9a.com wrote: >> I believe all RG8X has a .242 diameter PVC jacket and about the same loss. >> Certainly some brands are better made, I use only Belden 9258. > Not quite.

Below that value it will initiate tuning but finish at an SWR of between 3 and 6. When this happens if I connect my station 13.6v supply or an external 12v battery supply it will immediately tune to the expected low SWR. Elecraft tech support was a bit non committal on this issue. They said that 10v was close to the minimum value for the relay drivers to operate properly. This is a bit strange as one does not have to operate long with internal NiMh batteries before the transmit voltage drops below 10v. An easy work around is to perform my portable tuning when I first start operating. Still this seems strange behavior for a rig designed to work on the internal battery pack. Is this normal operation for the internal tuner? If not, then what should I check? I thought that tuning at a lower power might help but the manual states the tuner operates at either 2w or 3w and the value is not under user control.

I think what you?re seeing is not enough forward power to qualify the SWR readings. If the load impedance you?re working into is low (on a given band), the instantaneous key-down TX current drain will go up and the forward power might drop below the minimum required level for accurate readings. The ATU will skip LC combinations that don?t meet the measurement criteria. The effect could be made worse by batteries that have higher ESR, which varies with state of charge, number of charge cycles, and temperature. Any increase in ESR reduces key-down max power output. To see if the bridge is working correctly, connect the rig to a dummy load, run it from 10 V, turn the ATU off, and check the key-down SWR reading (TUNE) at 0.5 W, 1.0 W, and 2.0 W. Let me know what you find. 73, Wayne N6KR > On Feb 26, 2018, at 4:36 PM, AL7CR wrote: > > My KX3 internal tuner works perfectly at transmit voltages above 10v.

It s a much better investment to step up to the next larger diameter coax, especially at 50 MHz. LMR400 or LMR400-DB (waterproof flooded coax) are much better choices for 100 foot cable lengths at 21 MHz or above. Of course its hard to beat LDF4-50A but at a cable length of only 100 feet the difference in loss compared to LMR400 is less than 1/2 dB at 50 MHz. You'll never notice the difference. LDF4-50A or LMR600 is an excellent choice for a 200 foot coax length at 50 MHz. Much beyond 200 feet at 50 MHZ and LDF5-50A or LMR900 is a better choice. All of this assumes proper installation.

All was fine when I first installed the KRX3, right after it was released. However, when I installed the new K3SYNA boards the audio problem for the sub receiver manifested itself. I have verified that the settings and filters for the sub receiver are the same as the main receiver. Note that the RF signal between the two receivers is identical, as shown on the K3 S-meter and the P3 display. Recently I noted the latest KRX3 installation manual (downloaded from electraft.com) has a section entitled "Checking and Modifying Resistor R91 and DAC Input Circuits?. The manual I followed when installing my KRX3 only had a similar section entitled ?Checking and Modifying Resister R91?. The latest KRX3 installation manual states that the missing step involves cutting two traces on the main board board to the left of R91, with the justification that ?This modification ensures the digital-to-analog converters (DACs) always receive the proper signal levels.

In-Reply-To: References: Message-ID: Hi Jim, Since MSK144 has a bandwidth about 10 times the size of JT65A, I expect that any KX3 calibrated with the temperature compensation routine (http://www.elecraft.com/manual/KX3%20Custom%20VFO%20TC%20rev%20A9.pdf) should work OK. As you know, KX3 units with number above about 10,000 have the new main RF board, and should be quite stable even for narrower weak signal modes as long as the temperature compensation routine is done correctly. My early KX3 is number 800 something, so it has the original RF board, and there was a big problem with resistors heating up during transmit which caused the nearby oscillator to change frequency suddenly.? Five years ago, I had hoped that adding big heat sinks and coupling the oscillator to those would make the KX3 stable enough for JT65A on 6m for EME.? Although it helped, the ultimate solution was to remove the two problem resistors from the RF board, and replace them with a single tiny flange mount 20w resistor (AVX100) mounted directly to the case/heat sink, and coupling the temperature sensing IC more closely to the oscillator.? The stability now rivals my K3 with the optional high stability oscillator. Full details of the modifications are shown on my web page here: http://www.bigskyspaces.com/w7gj/KX3HeatSinks.htm My current objective in improving the stability was to be able to use the KX3 in FT8 mode for SOTA activations.? I now feel very confident that the KX3 is stable enough for that, or for other weak signal modes such as JT65A even up on 6m.

I was chasing 3D2EU on 80m this morning and ran into this problem ? sub receiver turned on, but the right headphone went dead. I was trying to hook up the Line Out to see if I was getting audio there, when I went ahead and pressed the memory 4 button to send my call again. Lo and behold, the sub-receiver came alive again in the right headphone again when the rig stopped transmitting. If anyone has insight into this intermittent problem, I?d appreciate it. Apparently transmitting ?fixes? it. I?m also going to see if the line out has audio when the sub receiver is active, but the headset is not. (3D2EU got really strong just after sunrise, but I didn?t manage to work him on 80m. Next time.)

I have run the test you suggested with the following results. Test Conditions Tuner bypassed, KX 3 connected via 18" commercial RG8X patch cable to dummy load, power via internal Eneloop batteries with three charge cycles since new, frequency 10.136 Mhz, receive battery voltage 10.8v, battery voltage during transmit 10.2v Results .5W SWR no reading (double dashes) 1.0W SWR 1.0 - 1 2.0W SWR 1.0 - 1 Stepping the power up in .1w increments from .5w gave no SWR reading until .8W which was 1.0 - 1 The above test was then run at a frequency of 14.074 with the same results. I then repeated the above tests with two other convenient power sources. An external sealed lead acid UPS battery which gave a receive voltage of 11.0v and a transmit voltage of 10.9v. and my station power supply giving a receive voltage of 13.6v and a transmit voltage of 13.5v. The result of the tests with the alternate supplies were exactly the same. Hence it appears that at transmit voltages from 10.2v to 13.5v, a KX 3 power setting of .8w is required for an SWR measurement to be obtained. The two antennas I was attempting to tune which led to the original question were a 135 foot doublet at 30 feet and a Buddistick mounted to my shop picnic table. The doublet does indeed have a low impedance as you suggest. I have not measured the impedance of the Buddistick. I am quite interested in your analysis of the above results. Should the KX 3 give an SWR reading into a dummy load at .5W output? If so, what can be done to adjust my unit. 73 de AL7CR On Mon, Feb 26, 2018, at 4:57 PM, Wayne Burdick wrote: > Hi Dean, > > The latching relays in the tuner should work just fine at low supply > voltages; they run off a voltage regulator, so their coils should see 5 > V even when the rig is running from as low as 8 V. > > I think what you?re seeing is not enough forward power to qualify the > SWR readings.

The receivers should have the pullup resistor to whatever the appropriate voltage needed (within reason) *and* a steering diode in series with the input. This will prevent another device with a higher voltage from feeding current back into the device which could damage semiconductors.

But many (most) ham devices do not do it that way, they expect the pullup resistors will be provided by the driver gear. So, because of that, Elecraft added pullup resistors to the band data outputs of the K3 long ago. So yes, we are left with a situation that often requires steering diodes. 73, Don W3FPR On 2/27/2018 3:48 PM, ab2tc wrote: > Hi Don and all, > > Hear,hear, Don.

One is the filesystem type, and FAT32 is pretty common. The other one is whether there is an MBR with a DOS partition, or the more recent GPT. If you were to take a flashdrive, put it in a Mac, and format it as "one partition, FAT32", I think you will end up with EFI. My impression is that the Elecraft firmware requires not only FAT32 but also MBR partitioning instead of GPT partitioning. But I am only 80% sure. 73 de n1dam From netbsd21 at gmail.com Tue Feb 27 19:40:17 2018 From: netbsd21 at gmail.com (Scott) Date: Tue, 27 Feb 2018 18:40:17 -0600 Subject: [Elecraft] K3s Low sub receiver volume In-Reply-To: <57CED875-FE0D-4721-AD6F-CD131E816C22@mac.com> References: <897A28DB-D125-4670-B5F6-73398AE1DA5B@mac.com> <5A957273.4010404@comcast.net> <7DC62A85-404A-4BAA-A094-1C4DC3F7BF8A@mac.com> <164ADAE0-237C-4FC0-B7A9-A894AEA4EE80@mac.com> <5A958275.8080202@comcast.net> <57CED875-FE0D-4721-AD6F-CD131E816C22@mac.com> Message-ID: <5e0bf6e2-57e3-67c1-63aa-c5419bfa2b82@gmail.com> Check NR and ATT are the same on both main and subrx.

Actually, most devices that use BCD "band data" expect an open emitter driver not an open collector driver. Open emitter will *source* voltage for logic high and be open circuit for logic low. This is the convention from the early Yaesu rigs which were the first devices to support "band data" (it is the way the FL-7000 and Quadra amplifiers operate). You will find the W9XT BCD10/BCD14 decoders with their opto-isolator inputs work just fine with the "open emitter" drivers. Other devices designed with Yaesu transceivers in mind have appropriate current limiting (series) on the input lines and "pull down" (parallel) resistors on the logic gates. Some "standard" devices (Top Ten BD-Y and the original microHAM Band Decoder) will provide both current limiting resistors and internal pull-ups but I have not seen any amateur product with series diodes in the band data lines. 73, ...

In the communications (non-ham) world, the expectation is that the driver device produces either a logic low (short to common) or a logic high ( open circuit). Look at the data sheets for "line drivers" and "line receivers" to check out what I am saying. Open collector or open emitter does not make a difference in function, it is only a circuit design decision. Yes, open Collector (or open drain) is commonly use in logic where the active state is zero volts (transistor or FET conducting to ground). The open emitter design is the opposite. A conducting device will provide a voltage on the line (or signal) being driven. The point is that in a properly designed communications system, the drivers provide either conduction to ground or an essentially open circuit to the communications line (think of a relay being either open or closed). The receiver provides the voltage to detect whether the driver is in an open circuit or closed circuit state. If there are multiple receivers in the system, only one can be "boss", and that one determines the open circuit voltage and contains the pullup resistors for the system. Other receivers work in listen mode and will contain no pullup resistors or active drivers. This whole situation goes back to the "one driver, one receiver" condition. Only one driver can exist on a communications system without conflict. Multiple receivers are possible, but only one (at the far end of the line) should provide the pullup resistors. All other receivers must be only in the listen mode. 73, Don W3FPR On 2/27/2018 8:06 PM, Joe Subich, W4TV wrote: > > > But many (most) ham devices do not do it that way, they expect the > > pullup resistors will be provided by the driver gear. > > Actually, most devices that use BCD "band data" expect an open > emitter driver not an open collector driver.?

As such, any "industry standard" is moot. The design is for active high/voltage source (to +12V originally) and was not intended for any purpose than providing band switching for the FL-700 then the Quadra. It would seem to me that any product that claims to inter-operate with the Yaesu "Band Data" would emulate or at least be compatible with that behavior - including the ability to *source* sufficient current at +12V. These devices are not operating in the "communications (non-ham) world", they are strictly amateur products. 73, ...

The point is that the devices don't work together because the third party manufacturers did not bother to understand the Yaesu design and take the necessary steps to be compatible. Yaesu's only purpose was to provide band switching data from the transceiver to a Yaesu amplifier. Their was no reason to design their system according to some inapplicable "standard" from the data processing world. Third party manufacturers need only provide a low impedance source of +12V for a logic high and open circuit for a logic low on the "transmit" side to emulate the Yaesu transceiver. On the receive side, any device that would connect to a Yaesu compatible transceiver needs to tolerate +12V on the input and have a moderately high (1 - 2K) pull down on any logic inputs (if it uses logic inputs); opto-isolator inputs simply need the appropriate current limiting resistors for 12V inputs (or +5V inputs given that many transceivers have failed to provide +12V logic high outputs). The bottom line is that this is not a "standards based" application. If one is going to provide (or use) BCD "band data" the device must closely emulate the Yaesu transceiver or clearly state that its signaling levels are not [guaranteed] compatible with Yaesu. 73, ...

Yes, if another transceiver manufacturer chooses to emulate Yaesu's protocol (BCD based "band data" with 160M = 1, 80M = 2, 40M = 3, 30M = 4, 20M = 5, 17M = 6, 15M = 7, 12M = 8, 10M = 9 and 6M = 10), they should also emulate the signal levels. Icom and Kenwood have spoken, Icom used its own proprietary "Stepped Voltage" for the IC2KL/IC4KL and certain antenna tuners (which Elecraft supports in the KPA500 and KPA1500), while Kenwood have never provided any "band Data" outputs. I don't know/care what Flex are doing in their current "radios" - their older products could be made to properly emulate the Yaesu Standard by running a third party software application that drove an LPT port in the computer that did the majority of the Flex's "work" - that LPT sourced sufficient voltage/current (in "full power" ports) to be compatible with the Yaesu implementation. 73, ...

There certainly is no problem at the 5 volt level, that is entirely within the range of the + level valid RS-232 signals. The possible problem is with the low level. A proper RS-232 receiver should ignore levels between -3 volts and +3 volts because it could be in a range defined as noise. However, all receivers are not designed to ignore a 0 volts low level. The receiver on the KX2 and KX3 as well as the XG3 (and probably others as well) will interpret 0 volts as a low level. Note that the 'real' RS-232 spec is written for very long communications lines. Short lines (10 feet or so) can take liberties with the levels if the receivers are such that they can tolerate those switching levels yet will accept signals with the full RS-232 voltage swings. Properly connected, you would need to have the KPA1500 TxD disconnected and depend on the PC application to poll the radio while the KPA1500 'listens' in to get its frequency information. Without the PC connection (and the KPA1500 TxD connected, the KPA1500 will poll the radio for that information. RS-232 is point to point communications and not multipoint, although there can be multiple receivers listening to the communications, there can only be one driver. Sort of like ham radio - everybody can listen, but if two operators transmit on the same frequency, they will QRM each other and "data corruption" occurs. 73, Don W3FPR On 2/28/2018 6:30 PM, Paul Baldock wrote: > The manual on page 24 says: > > Serial: A Kenwood, Yaesu, Elecraft K2, K3, K3S, KX2, or KX3, or > FlexRadio? transceiver that responds to IF; FA; FB; FT; polls with > frequency and VFO information.

There will be no issue with the +6V from the TS-990 true RS232 being heard by the KPA-1500 and PC, however I am concerned that the -6V from the true RS232 might get clamped close to 0V by the KPA-1500 input and so screw up communications between the TS-990 and the PC. Hopefully the KPA1500 has a reasonable input resistor and so clamping will be minimal. - Paul At 04:25 PM 2/28/2018, Don Wilhelm wrote: >Paul, > >It is possible that short runs of "RS-232" can operate on TTL levels. >There certainly is no problem at the 5 volt >level, that is entirely within the range of the + level valid RS-232 signals. > >The possible problem is with the low level.

The issue is that of false powering of receiving devices. In this day of low power micro controllers and other digital devices, the device can actually be powered through the I/O port when the device is supposed to be off. The I/O current flows into the input pin, through the protective diode and onto the Vcc rail, bypassing the main VCC pin. This means the device may be partially functional, and not under proper control. It can lead quickly to the destruction of the device. This is the big reason for modern-day communications techniques between devices, and why protective measures must be taken to avoid false powering other devices. Yes, devices connected to BCD band data _can_ be false powered. We do see it. It makes me wonder if perhaps the old Yaesu method should be retired and no longer used. I certainly won?t be buying any of those devices. There is no reason that BCD data should not be carried at logic levels between devices if these measures have been taken. There appears to be two separate ?standards? at this point, the Yaesu 12V system, and the 5 volt TTL logic level system. Devices that play in each should be clearly marked so the buyer can beware. Unfortunately many are not. This does provide an opportunity for the creation of interfaces which translate between the two methods, providing protection to both the transceiver and the device being driven. The problem comes from hams who don?t realize the issue and try to connect the two. Either they get frustrated because the connection doesn?t work and no harm is done otherwise, or they get really frustrated because the 12V driver blows up their device. Luckily we don?t see the latter happen that much. But arguing that the ?old ways? are somehow better, when we know otherwise, doesn?t do very much good.

If the device is designed to be +12V tolerant (input current limiting and properly selected "pull down") there is no damage. The input current limiting and pull down also keeps any voltage on the inputs low enough to prevent "false powering." For that matter, the BCD signals are DC and the third party device could use shunt zener diodes on the signal lines to limit the input voltage to and prevent false powering. It's only when the third party device makes assumptions without understanding the history of the Yaesu "Band Data" (or "Linear") interface that one has an issue. 73, ...

The issue is that of false powering of receiving devices. In this day of low power micro controllers and other digital devices, the device can actually be powered through the I/O port when the device is supposed to be off. The I/O current flows into the input pin, through the protective diode and onto the Vcc rail, bypassing the main VCC pin. This means the device may be partially functional, and not under proper control. It can lead quickly to the destruction of the device. > > This is the big reason for modern-day communications techniques between devices, and why protective measures must be taken to avoid false powering other devices. Yes, devices connected to BCD band data _can_ be false powered. We do see it. It makes me wonder if perhaps the old Yaesu method should be retired and no longer used. I certainly won?t be buying any of those devices. > > There is no reason that BCD data should not be carried at logic levels between devices if these measures have been taken. There appears to be two separate ?standards? at this point, the Yaesu 12V system, and the 5 volt TTL logic level system. Devices that play in each should be clearly marked so the buyer can beware. Unfortunately many are not. This does provide an opportunity for the creation of interfaces which translate between the two methods, providing protection to both the transceiver and the device being driven. The problem comes from hams who don?t realize the issue and try to connect the two. Either they get frustrated because the connection doesn?t work and no harm is done otherwise, or they get really frustrated because the 12V driver blows up their device. > > Luckily we don?t see the latter happen that much.

Rechargeable Ni-MH batteries will also last a longer time. If you do not have the internal charger, you will have to remove them for charging, so carry a 2nd set of fully charged batteries. Two hours seems like a short time for receive only. If you are using alkaline batteries, use a good brand - the off-brand bargain batteries are often short lived. 73, Don W3FPR On 2/28/2018 10:21 PM, Dennis W0JX via Elecraft wrote: > I have just put my KX-3 into portable service trying to locate noise sources around my property and neighborhood.
