"...batteries were quite discharged..." Bob, Glad you got things working. Keep in mind that if any cell was discharged below 1 volt, there is a likely chance that it has been damaged and cannot be recharged successfully.? That is why the KX3 shuts down at 8 volts, to protect the cells (1V per cell X 8 cells = 8V).? That is also why it is important to use Low Self Discharge (LSD) cells.? Non-LSD cells will continue to self-discharge below that 1V level, destroying themselves.

I chase 6M grids. Last season, I worked >140 grids, 40 of which were new ones. That's not easy to do from the west coast when you already have 350 confirmed. 13 were JT65 or JT9, 14 were FT8, 10 were MSK144, 3 were CW, and 1 was SSB. When you reach that level, the grids you're missing are mostly those with low population density. A relatively small number of hams working 6M know CW, and all of the WSJT modes are 20 dB or more better than SSB. So FT8, by virtue of its new popularity, is lighting up a bunch of grids that were otherwise not available for marginal conditions. In two strong openings about ten days ago, I worked more than a dozen JA stations in 9 grids! All but one has already been confirmed in LOTW. That's another strong point -- in general, those who use digital modes are FAR more likely to be on LOTW, which saves a lot of postage if you're chasing awards. 73, Jim K9YC From alorona at sbcglobal.net Fri Jun 1 12:59:22 2018 From: alorona at sbcglobal.net (Al Lorona) Date: Fri, 1 Jun 2018 16:59:22 +0000 (UTC) Subject: [Elecraft] Boldly OT: 6 meter Sporadic-E season and the FT-8 microjuggernaut In-Reply-To: <2C601204-FF2F-4BB8-B93E-1058BC0512C0@elecraft.com> References: <2C601204-FF2F-4BB8-B93E-1058BC0512C0@elecraft.com> Message-ID: <94714285.7870753.1527872362860@mail.yahoo.com> I wrote an April Fool's article back in like 1999 (I might still be able to find it on dejanews) describing a make-believe ARRL contest which was totally automated; contesters could come home from work and peruse their logs to see what stations their computers had 'worked' that day.?

When parody becomes reality, it's no longer funny. I'm chagrined that that fictitious day appears to have finally arrived. I suspect you haven't used any of the WSJT modes. Operator skill and experience significantly increases the likelihood of completing QSOs, especially QSOs with stations that you want to work. Indeed, auto sequencing often gets in the way of that, responding to calls from locals when DX (or stations in rare grids) are calling you. 73, Jim K9YC From xdavid at cis-broadband.com Fri Jun 1 13:27:10 2018 From: xdavid at cis-broadband.com (David Gilbert) Date: Fri, 1 Jun 2018 10:27:10 -0700 Subject: [Elecraft] Boldly OT: 6 meter Sporadic-E season and the FT-8 microjuggernaut In-Reply-To: <94714285.7870753.1527872362860@mail.yahoo.com> References: <2C601204-FF2F-4BB8-B93E-1058BC0512C0@elecraft.com> <94714285.7870753.1527872362860@mail.yahoo.com> Message-ID: <6478eb4e-5e45-d543-ffc9-d9b12851d5a9@cis-broadband.com> I think it's way too simplistic to dismiss FT8 as being merely a phase.? I haven't tried it yet, but it seems to me that FT8 contacts have similar appeal to folks who try to rack up as many countries or other entities as they can ... where having a chat isn't the main intent.? I've made a ton of CW contacts where all I had to do was copy a callsign and push a button on my keyboard to send my info.? I doubt you can make a strong case that those were much different than an FT8 contact. It is certainly likely that some other mode will eventually take it's place, but I don't see sub-noisefloor modes ever going away. They simply have too much benefit for hams with antenna and/or power restrictions.? Besides, I could probably argue that exploring new modes is well within the spirit of ham radio ... something you seem to have forgotten. Dave??

The distinction is between transmitting and receiving. In receiving, the difference is that in CW and SSB my brain is an integral part of the process of getting the signal information from audio to log, no silicon required or desired. Development and maintenance of the skills required to do that accurately and efficiently are what I find most rewarding about operating. In that respect, I've been "geek free" since 1964. 73...

When the bulk of an eight-hour work-day is spent in front of a monitor, it should come as no shock that an entire generation will prefer making QSOs with keyboard-keys rather than telegraph-keys. For them it requires less skill, less time, and less patience . . . precisely the kind of activities most sought by millennials. Everything on this earth evolves, including amateur radio, and evolution has never been straight-forward.? It explores, imagines, and experiments.? It leaves behind a trail of bad ideas, weird adaptions, and dead-end cul-de-sacs.? At one time trilobites ruled the oceans.? The oceans did not change, but the trilobites went away. My CW class on Saturday mornings has several IT guys who work for the State of Missouri.? They are fascinated by code ... not their kind of code ... Samuel F.B.'s kind of code.? They learned it mostly on their own and want to get better at it.?

When the bulk of an eight-hour work-day is spent in front of a monitor, it should come as no shock that an entire generation will prefer making QSOs with keyboard-keys rather than telegraph-keys. For them it requires less skill, less time, and less patience . . . precisely the kind of activities most sought by millennials.

It leaves behind a trail of bad ideas, weird adaptions, and dead-end cul-de-sacs. At one time trilobites ruled the oceans. The oceans did not change, but the trilobites went away. My CW class on Saturday mornings has several IT guys who work for the State of Missouri. They are fascinated by code ... not their kind of code ... Samuel F.B.'s kind of code.

Water cooling might work if you wish to modify it. :) But, there is no free lunch as was mentioned. Be prepared that any 1500 watt LMDOS amp requires cooling but since there is no tube, they are built in smaller boxes, so you get smaller fans that have to move more air. The B26 is somewhat quieter I think, but they worked on some things to make it quieter like extending the fan out the back so there is less disturbed air when it hits the fan blades. They aren't that loud and if were good headphones, you won't notice at all. my 2 cents, Mike va3mw On Fri, Jun 1, 2018 at 8:32 PM, Bill Stravinsky via Elecraft < elecraft at mailman.qth.net> wrote: > Rich > > You pretty much hit the nail on the head about solid state amps.

Doesn't matter what the converter is (transistor, tube, resistor, etc.). It all behaves the same. Need to get rid of 750 watts of heat. The only difference may be the way the heat is taken away of the converter... convection (heat sink), forced convection (heat skin plus fan), liquid convection (water cooled heat sink). The poison is the heat removal device not the converter. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch ? K9ZC Staunton, Illinois Owner ?

There are several issues that might be affecting the number of CW signals heard. One is the relative lack of CW skills in the general ham population. I'm a poster child for that lack of skill. I passed the 5 WPM test when I got my extra. Did that mean I could play in the 15 to 40 WPM world we see on the bands? Of course not. I've been trying to improve my CW. I started by chasing some of the big DXpeditions. I got so I could recognize my CQ, call sign, and TU, which let know whether to press the AE6JV key or the 5NN TU key. My vocabulary expanded to recognize things like CQ EU etc. and avoid being a complete boor. I also started running contests in S&P mode, learning how to decode call signs and exchanges, usually only after many repeats. Now I even try checking into the weekly Elecraft net. Thanks for putting up with me Kevin. I still like the digital modes. I fell in love with PSK31 after operating it a Field Day. It was a lot like computer chatting, which I had done as a part of my job in my last job before retirement. Another is the kind of QSO operators want to have. I was quite surprised when one of the younger members of our club -- in his 30s -- said he liked contesting because he didn't have to listen to old men talking about their medical problems. He is a good contester and regularly outscores me in contests. This kind of operator will be quite happy with FT8, or canned exchanges in CW and digital modes. I've met many of them on PSK, even when I try to indicate I'm up for a bit of a chat. I got to really like the automatic features when I was in the depths of side effects from my cancer treatment. I could sit back in my chair and make contacts without having ot expend a lot of the energy I didn't have. I do think the advertised 20-24 dB below the noise floor is a bit of crock, but not entirely wrong. If I understand the situation correctly, the noise is measured in a 3KHz band width while the signal is 50 Hz wide. That factor of 60 should be responsible for 17.8 dB of the advertised noise immunity of the mode. The other 2 to 6 dB is a real advantage over CW with the tightest K3 DSP bandwidth. (APF can do better, but dies when other signals, like DQRM, are near the desired signal.) When I was operating portable with a barefoot KX3 in New Hampshire a month ago using FT8, I had real problems getting all that juicy DX in EU to answer me. Finding an open space in the band was hard. Finally I tried finding an open transmit window and calling CQ. The DX came to me, and I contacted a few ATNOs. I had to move frequently as other stations started transmitting in the same window I was using. It's always worth pausing to see if you still have the window. Here full break in CW has a real advantage. SSB has some of the same advantage because transmissions aren't synchronized, as they are in FT8. To try to answer Wayne's question, perhaps setting up schedules using the Internet would help. Also calling CQ can help a lot. I was asked to test how 15M was holding up in preparation for Field Day. I found the band dead until I tried calling CQ. I didn't make many contacts, but calling CQ brought stations out of the woodwork including some DX. I agree with Jim's comments about LotW. My truly spectacular LotW success was with the 5 FT8 out of state 6M DX contacts I made last new years eve. All are LotW confirmed. Out of 88 FT8 contacts logged in this last trip to New Hampshire, 55 or 62.5% have been confirmed with LotW. Compare that with the CQ WPX CW contest last weekend. I logged 255 QSOs and have 80 LotW confirmations 31.4%). Of course, the WPX contest was quite recent, and more confirmations should trickle in. It is also almost certain that I blew copying some of the calls which would push down the number of confirmations. 73 Bill AE6JV On 6/1/18 at 8:46 AM, n6kr at elecraft.com (Wayne Burdick) wrote: >At first I thought it was my receiver.

In-Reply-To: References: Message-ID: <001201d3fa1b$fa36e940$eea4bbc0$@comcast.net> I personally think all the banter about KPA1500 fan noise has created confusion. Yes, the amp has three fans with five selectable fan speeds..and since the amp is small the fans are necessarily small and therefore must run faster ?. and as the fan speed increases the pitch and noise levels increase.. and the higher fan speeds do indeed create significant noise, but the higher speeds will rarely (if ever) be needed. I have had my KPA1500 about 3 months now, and have manually switched to level 3 just a couple times (cq running during cw contest and major cw split pileup), and thus far I have never had to use levels 4 or 5. The fans operate automatically as per heat sink temperature but can also be manually controlled. Fan speeds 1 and 2, to me, are just like any other amplifier, and noise is not problematic. Levels 3, 4, and 5 however are definitely noisy and can become annoying?. But again, those speeds are rarely necessary. IMHO, with five selectable speeds, the KPA1500 could very likely have the most capable cooling system available in any amateur amplifier.... and I call that a plus. The three additional amplifiers in my shack (Alpha 9500, Icom PA1 and Alpha 89) make noise too, but it?s probably a good bet that they do not have cooling capability that matches the KPA1500?s five speed fans.

Boehner MD) Date: Fri, 1 Jun 2018 23:07:20 -0400 Subject: [Elecraft] KPA-1500 Fan Noise Message-ID: <002901d3fa1e$d39e0db0$7ada2910$@yahoo.com> Just thought I would add a few thoughts as far as the fan noise. I'm not certain a YouTube piece would help, but perhaps personal observations might. First, via the menu, you can select the minimum fan speed, 0-5. Of course, the fan speed will go up with the Amp temperature. These are my personal observations: 0-Nothing 1-Barely perceptible 2-Acceptable fan noise, even for SSB operating. Low pitched whine 3-The noise and the pitch of the whine is past the acceptable point. Even a very directional mic will probably pick up the noise. This is where Noise Cancelling headphones would start to help. 4-Louder and higher pitched whine 5-Very loud and higher pitched whine So, the fan noise becomes particularly bothersome on level 3 and above. If you are doing CW and/or Digital, the noise will only be a factor with the operator. On SSB, the noise will probably be noticeable on the air. However, the SSB duty cycle may not require higher fan speeds. Those who have been active in contests will probably know that answer. Rich, if fan noise is going to be that strong a factor, perhaps you should be looking at tube amps instead. Personally, if I found the KPA-1500 fan noise excessive in the future, I would plan on moving it off my desk or remoting it rather than replacing it. It's integration with the K3 would be very hard to give up. ?73 de JIM N2ZZ #106 -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Dr. William J.

So just a bit of thermodynamics... if the input to any amplifier is 1500 watts and it is 50% efficient, since energy is conserved, 750 watts will come out in another form.. and in this case it's heat. Doesn't matter what the converter is (transistor, tube, resistor, etc.). It all behaves the same. Need to get rid of 750 watts of heat. The only difference may be the way the heat is taken away of the converter... convection (heat sink), forced convection (heat skin plus fan), liquid convection (water cooled heat sink). The poison is the heat removal device not the converter. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch ? K9ZC Staunton, Illinois Owner ?

Rich You pretty much hit the nail on the head about solid state amps. As they say there's no free lunch. Solid state has made great strides in high power ampsbut its still solid state and a p/n junction or some form thereof. 1500 watts of heat in those junctions has to be cooled down or it won't be long before it needsnew parts. Depending on your operating habits (contesting, casual, or whatever) there will be varying degrees of fan noise. The higher the duty cycle the higher thefan requirements. Pick your poison, a small light weight amp easy to move around or one you need a fork lift to pick up. I prefer tube amps for a few reasonsand have the Acom 2000a (and an Alpha 89 that now sits in the living room temporarily) but I'm still glad I got the kpa1500 at least so far. The kpa sits nicely on top of the Acom without causing the table they sit on to crash to the floor in pieces, hi. I'm surprised nobody has made a you tube ofthe amp in operation actually. But there are only just over 200 of the new amps out there. Good luck with your investigation, Rich.

The amplifying device must dissipate considerable heat because we are running Class AB and because of all electronic devices are naturally lossy. Remember that this heat is generated not only in the RF transistors, but also in the power supplies, bias circuits, lights, etc. There are lots of heat sources in every amplifier. I can honestly say that my KPA1500 is considerably quieter than the Expert 2KFA that I just sold and I would have to say it is quieter than my old Alpha 87A. I do operate it at full 1.5 KW output but I suspect my duty cycle on CW has not caused it to so how that the fans max out. Same for the 2KFA, but even at low speeds, it was far noisier. And, the 2KFA has REALLY loud T/R relays!

Obviously the Elecraft Reflector is a mainstay of CW ops. I've been using digital modes one eme since 2003. Back then the introductory program was JT44 which was supplanted by JT65 within a couple years. Then many variants were done to address conditions on certain bands or certain prop modes. WSJT was formed as the folder holding most of the new formats plus JT65. MAP65 came out with ability to display 100-KHz of a band showing all signals and even decoding all of them to display activity over the sub-band. Kind of like a P3 on steroids. The two digit negative signal strength numbers show SNR based on a bw of 2.5 KHz. -18 is about the lowest level signal one is able to hear. If one were using a 500-Hz CW filter the same signal SNR would be -11, or with 100-Hz super narrow bandpass the SNR = -4 dB which a good CW op should be able to copy (perhaps with a little difficulty). It all started on 2m-eme, and for years mainly was about eme. The "old guard" on eme grumbled and said it would never last. Today there are maybe a couple dozen CW-only eme ops on 2m in the world; 99% have gone digital. FT8 (as I understand was created by Joe Taylor - K1JT for HF users in mind). It started when a few tried JT65 on HF, then discovered WSPR. Now FT8 is gaining in popularity on HF. Whole world is moving on. K3 and KX3 are SDR's. Everyone on this list used a computer to read it.

Follow this link to view: https://vimeo.com/273064144 In addition to the KPA1500 the video also includes footage of my Alpha 9500 and Icom PA1 ? each running with their fans at maximum speed ? to provide a simple rather crude comparison. What do I think? I think that fan speed 1 and fan speed 2 on the KPA1500 are probably comparable to the fans that are installed on the other amplifiers as far as sound and efficiency are concerned and likely provide a similar degree of cooling at those speeds. And, I think that fan speeds 3, 4, and 5 (which are indeed noisy) provide the KPA1500 with enhanced cooling capability that is simply not available on other amplifiers.

No lawn mower, no umbrella, no place to store unwanted and unnecessary junk. You are livin' a dream. And you can string your dipoles from the Saguaro. Hey, if the arms are the correct lengths you can string some verticals to cover multiple bands. And if the arms are the same length maybe you can make a phased array?

I had a choice of Dayton blowers, one for ssb/cw (60 CFM if I recall correctly) and one for moon-bounce or key-down modes (100 CFM, I think).? I got the 100 CFM blower, anyway the one that moves more air; 100 CFM makes a lot more noise! The only discussion about blower noise was to provide this choice (sometime after I got my unit it became possible to purchase the 100 CFM blower but it ran at two speeds). I imagine that levels 4, and 5 are related to key down modes in KPA1500, and maybe level 3 as well.? I suppose one can reduce fan or blower noise to some extent by paying attention to relevant details about fan and noise but all significant variables held constant (like the size of the amp and the power output), there is no free lunch (as usual), solid-state or not. I recall the conduction cooled amps (no fan, no noise), one by Henry Radio (2 x 8873) and another by Heathkit (one 8873). You had to reduce power significantly for key-down modes, and neither amp made 1500 watts output rtty key-down (1000 watts cw for the Henry--but of course this was before the current maximum legal power output). Still, how long you could hold down the key depended upon ventilation of the amplifier. Heathkit recommended only 200 watts output for rtty. I imagine guys placed fans (making some noise) near the heatsinks! So, to put this into perspective, how long the key can be held down using kpa1500 at 1500 watts output power may have something to do with fan speed number five! If you want "almost silent high power", then try running kpa1500 at 500 watts output (about like a conduction cooled amp--but don't hold that key down too long without ventilation). 73, Will. wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Sat, 6/2/18, Jim via Elecraft wrote: Subject: Re: [Elecraft] KPA-1500 Fan Noise To: "John Perlick" Cc: "elecraft at mailman.qth.net" Date: Saturday, June 2, 2018, 6:20 AM I don?t have a dog in this fight - someone who spends half the year (the half with all the good contests) in a Florida condo is not a candidate for buying amps.

I leave my K3 here for remote use and use the amp at my winter home in Florida to use with my Flex 6500 with a Steppir Vertical antenna without the KAT500 tuner. When I got up here I installed the KIO3B option. The install went well with no issues, all looked good so I connected the K3, P3, KAT500, and KPA500 with the Elecraft provided cable set like I do every year. The issue I'm having is an SWR difference between the KAT500 and the K3. For example if I use the K3's internal tuner I can on a chosen frequency achieve an SWR of 1/1. I the put the internal K3 tuner in bypass mode and take the KAT500 out of bypass and set to auto. I then use the xmit button on the K3 to create a tune signal to be sent to the KAT500. The K3 then shows a 1/1, the KAT500 about the same but the KPA500 which is in STBY mode shows around 3/1. What this causes to happen is the Amp will fault out if I try to use any power output. If I check the antenna with a trusted SWR meter I see 1.3/1 at the frequency of use. I upgraded the firmware in all the devices in use, I also did a reset of the KAT's stored frequencies memory, and checked both the amp and tuner with the utility programs. I'm going to call Elecraft on Monday, anyone have any ideas in the meantime I can try? 73 Jeff kb2m From n1sv at comcast.net Sat Jun 2 12:07:37 2018 From: n1sv at comcast.net (Les Peters) Date: Sat, 2 Jun 2018 12:07:37 -0400 (EDT) Subject: [Elecraft] KPA-1500 Fan Noise In-Reply-To: References: Message-ID: <671987067.584291.1527955658276@connect.xfinity.com> Jim I agree with your personal observations.

RF sunburn :-) Hey, transistors can run pretty hot too, although they should not melt the solder. Case temp can get to 150 deg C and junction temp to 225 deg C. Yes your finger will burn on the case. And yes, the life of many power devices gets derated based on junction temp. As an example an LDMOS may have an MTTF of 1M hours at 150C and 70K hours at 225C junction temp. JANS space transistors are burned in at 220C and tested up to 125C case temp.

One other thought to keep in mind - solid state amps need a lower delta T than tube amps. Tubes like to run hot - solid state devices not so much. I've seen a tube with the fins so hot that the solder was in globs, while the transmitter was still operating. I doubt any solid state final would have survived that heat. When we installed our solid state TV transmitter, it was a new learning curve in cooling. Both transmitters were 30 kW class AB1. The tube transmitter moved air faster through 3 tubes but had almost 3 times the temperature rise than the specs for the solid state transmitter. Our HVAC company and architect worked on several complex systems with air mixers until we just decided to use wall mounted air conditioners into the room behind the transmitter racks and exhausted to the front of the transmitters. Our solid state transmitter did meet the OSHA limit for 8 hours exposure to noise but just barely. It was very noisy compared to the tube unit. No tube transmitter I have ever used had a temperature shut down on any of the tube stages. 73 George AI4VZ -----Original Message----- From: Don Wilhelm Only one bit of correction. If the output power is 1500 watts and the efficiency is 50%, that 1500 watts is only half the total power consumed, so there is 1500 watts of power that must be exhausted as heat. ______________________________________________________________ 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 tony.kaz at verizon.net From elecraftcovers at gmail.com Sat Jun 2 12:52:12 2018 From: elecraftcovers at gmail.com (Rose) Date: Sat, 2 Jun 2018 10:52:12 -0600 Subject: [Elecraft] OT: 6M proceedure Message-ID: IMO ? based on years of 6M operating.

Hopefully I won't piss off everyone... and it won't be too long. 0). First, monitor beacons or participate in the RBN for band openings and then call CQ on open bands. Heck, call CQ on "closed" bands... one never knows. I suspect there are more band openings than most would admit or even know about and maybe we need more hams willing to set up beacons. I once copied a SSB qso of ON4UN and a stateside ham on 15m when all the prop computer programs said 15m was closed. 1). CW ops should make MORE use of the computer... especially for calling CQ. Once a reply is heard switch to "manual" cw mode (this is nothing new) AND adjust speed to station answering your CQ. Nothing worse than an experienced cw op who won't bother to "talk" to a slow sending station... nothing. It just sends the inexperienced cwop to digital and/or ssb where someone will likely answer no matter the "speed". 2) CW ops need to not be prejudiced against keyboard sent code, especially at slower speeds or even someone using cw decoding sw. I think younger hams might actually do more if there wasn't such "stink" put on ops using a keyboard and decoding sw. Besides you do want to get younger hams interested in ham radio and especially CW... right? And as time goes on those young or even old keyboard cw warriors may or may not learn to send with a paddle or a key but you've got to get them interested in CW first. For some, it's an age vs. memory issue especially hams who started late in life. 3) Now to beat up the computer geeks. Someone could set up a twitter or gab account and advertise it to the ham community at large via reflectors and use the account specifically for reporting band openings. Then you could get notified on the ubiquitous smart phone and who knows maybe there is or will be soon a rig remote control app for your phone. 4) Digital mode software can be a bear to configure. Clearly there should be just one or two "tabs" max to get it working quickly and all the other program integration configuration is icing on the cake. Complexity in a basic "getting it working" configuration is not good. And how about making the program/app window and fonts larger for crying out loud... I don't see as well as I used to and with the proliferation of large monitors these programs are a pain to even see anymore. While this may increase digital ops I also believe that at some point even some digital ops will want to try and learn cw. 5) Finally, I've noticed that a lot of younger millenials like "old school" stuff from LP 33 records to radio. IF you can get them interested in Ham radio (a shameless plug for expanded tech privileges) there's a good chance they'll eventually want to learn cw one way or another. The point is, more hams equals more chances for someone to answer your cw CQ. I doubt any of that helps much except maybe paragraph 3, but there it is... thanks for letting me give it a shot.

It seems everywhere I read within Elecraft Documentation is that standard VGA cables should NOT be used. In regards to extensions, I do not know if they all work pin to pin, or that they are meant to just extend standard VGA cables. It certainly would be a way to extend the distance between the K3/K3S and the KPA1500, but still retain the functionality between the two. When the new firmware comes out, and the amp can be controlled by the function buttons on the K3 (PF1-operate/stby and PF2-antenna switch), it would be a sure winner.

Make certain the connectors are tight. Replace with a different coax if you have one. You can always do a check on the KPA500 wattmeter by connecting a dummy load to the KPA500 (no tuner). 73, Don W3FPR On 6/2/2018 11:48 AM, jeff griffin wrote: > I recently brought my KPA/KAT500 north for the summer and hooked up to my trapped multiband fan dipole that I use here in NJ.

For example if I use the K3's internal tuner I can on a chosen frequency achieve an SWR of 1/1. I the put the internal K3 tuner in bypass mode and take the KAT500 out of bypass and set to auto. I then use the xmit button on the K3 to create a tune signal to be sent to the KAT500. The K3 then shows a 1/1, the KAT500 about the same but the KPA500 which is in STBY mode shows around 3/1. What this causes to happen is the Amp will fault out if I try to use any power output. If I check the antenna with a trusted SWR meter I see 1.3/1 at the frequency of use. I upgraded the firmware in all the devices in use, I also did a reset of the KAT's stored frequencies memory, and checked both the amp and tuner with the utility programs.

I think that fan speed 1 and fan speed 2 on the KPA1500 are probably comparable to the fans that are installed on the other amplifiers as far as sound and efficiency are concerned and likely provide a similar degree of cooling at those speeds.? And, I think that fan speeds 3, 4, and 5 (which are indeed noisy) provide the KPA1500 with enhanced cooling capability that is simply not available on other amplifiers.

As you have pointed out 1 is barely perceptible and this helps to reduce the amount of time that fan speeds are on 2+. I'd like to have more separation between the K3S and the KPA1500 RF deck to further distance any noise but the KPAK3AUX cable is only about five feet long, it would be great if that were more like ten feet.? Since the cable pin out is straight thru I would imagine a DB15 VGA M-F extension cable would suffice?? That would put the potential fan noise even further away but have the RF deck still plenty close enough to view. Les, N1SV #113 > Date: Fri, 1 Jun 2018 23:07:20 -0400 >? ? From: "James F.

So, the fan noise becomes particularly bothersome on level 3 and above. If you are doing CW and/or Digital, the noise will only be a factor with the operator. On SSB, the noise will probably be noticeable on the air. However, the SSB duty cycle may not require higher fan speeds. Those who have been active in contests will probably know that answer. > >? ? Rich, if fan noise is going to be that strong a factor, perhaps you should be looking at tube amps instead. Personally, if I found the KPA-1500 fan noise excessive in the future, I would plan on moving it off my desk or remoting it rather than replacing it. It's integration with the K3 would be very hard to give up. > > >? ? ?73 de JIM N2ZZ >? ? #106 >? ? ************************** > ______________________________________________________________ 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 jboehner01 at yahoo.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k3wjv at yahoo.com From k6dgw at foothill.net Sat Jun 2 15:03:18 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Sat, 2 Jun 2018 12:03:18 -0700 Subject: [Elecraft] KPA-1500 Fan Noise In-Reply-To: References: Message-ID: <1e577518-7c98-298d-ca5a-00a33d3a9923@foothill.net> Yes John, and it turns out to be a fairly simple equation if you make a few assumptions.? Around 1958 or so and a student [sophomore], I spent the summer with a small crew building KPFK on Mt. Wilson in Los Angeles.? The TX was almost totally homebrew [REL serrasoid exciter], with 4 4-1000A's in the PA [4 parallel class-C 4-1000A's at 90.7 Mcs was a bit of a challenge [:-) ].? About to return to school, I was reviewing the physics I'd supposedly learned the previous year and realized I should be able to calculate the efficiency of the PA from the smattering of thermodynamics I knew.? Tx engineers don't have much to do until something breaks. I knew the pressure difference between the air inlet and the exhaust [quite small, there was a differential manometer], the filaments dissipated 600 W, nearly all in heat, and I knew the temp difference between the gozinta and gozouta air so I could calculate the mass of the air moving per unit time or so I thought.? Then, with the PA on and stable [3.5 A @ ~5.8 KV], I could do it again only this time calculate the power lost to heat the air.? Subtract the 600 W from the filaments, and I got 69.4%. I assumed the air was heated at constant pressure, my calculus hadn't progressed far enough to do otherwise. After I went back to school, they finally measured the efficiency on a 2-stage oil/water cooled dummy load and called me and said they got 71.3%.? If it doesn't go up the 3 1/8" hardline, it comes out as heat ... somewhere.? There's only two options. I'm a little surprised at the obsession with fan noise ... I'd like to hear about how much more DX everyone is working with a KPA1500. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/2/2018 1:06 AM, John Perlick wrote: > Bill Schmidt is right--you have to get rid of a bunch of heat--no matter what device you are using to amplify (tubes, transistors, or magic).

Yes the caution is warranted for "VGA" cables. They are not always pin for pin and can do two things wrong. One is that not all pins are wired and the other is worse as they sometimes tie the shields together shorting out needed pins. There are multiple versions of VGA cables. My source for the correct cables is L-Com here: http://www.l-com.com/d-sub-high-density-d-sub-cable-assemblies I've had good luck with products from them being reasonably priced and good quality. I'd just get the length I'd need rather than an extension. An extension adds another failure point as with all cabling jobs. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 6/2/2018 1:42 PM, James F.

The issue I was trying to point out and not doing a very good job is that with gab or twitter the band opening data could be "pushed out" to subscribers in near real time, something needed for quick openings on 6m. Besides who doesn't own a smart phone? I suspect a large percentage of hams do and if they want basic band opening data that surely is one way to "get it out" quickly unless there is some huge server delay. There may be something already out on the internet that does something like this I'm just not aware of it. I could be wrong, but a quick look around WSPRnet.org did not show me anyway to get data except for me going there and digging it out. Nothing wrong with that, just not what I thought Wayne was looking for. I had thought I might help out WSPRnet in the near future as the idea of running a low power beacon has peaked my interest of late. All the best and 73. Scott AD5HS On 6/2/2018 1:07 PM, Lynn W.

This was the response back then: Thanks for the contact.? To your questions on the AUX cables, you can actually connect 2 of them in series without a problem.? This will give you about 6 feet of cabling.? We've tested this with our E850463 cables on a KPA500 and it will work, assuming you don't have a problem with RF in the shack at 1500 watts. The limiting factor in extending the AUX cables is that the high-speed, single-wire AUX BUS system we use in the K3/K3S is extended to the KPA1500 so that the amp can 'talk' to the radio. ? The increased capacitance of the AUX cables are the limiting factor as extender cables are added. So, plan on a maximum of 6 feet or 2 E850463 AUX cables. Now that was back then and I don't know if there has been any more testing or engineering accomplished.? I opted for two cables to let me put the amp where I wanted it.?

If that is the case, did the assigned COM port get changed with the Windows 10 Update? Some have reported it has happened to them. To check the COM port that is assigned, open Device Manager and expand the PORTS listing. Then unplug the USB connector and see which COM port goes away - now plug it back in and observe which COM port is assigned. Plug that COM port into K3 Utility or any other application that you are using to communicate with the K3. If you don't see a COM port assigned, then suspect the USB to serial adapter - reload its drivers to see if that fixes it. 73, Don W3FPR On 6/2/2018 3:10 PM, Mark Wheeler wrote: > Wayne, > > No I cannot.

If so, it makes a lot of sense that you will see different SWR. The KPA and KAT are providing a completely different load for the K3. The better test is to feed the antenna directly from the K3 without the KPA and KAT in-line. I would expect you to see a closer match at that point, although I doubt they will ever be identical due to the differences in the directional couplers in the K3 vs the KAT500 (and KPA500 for that matter).

The install went well with no issues, all looked good so I connected the K3, P3, KAT500, and KPA500 with the Elecraft provided cable set like I do every year. > > The issue I'm having is an SWR difference between the KAT500 and the K3. For example if I use the K3's internal tuner I can on a chosen frequency achieve an SWR of 1/1. I the put the internal K3 tuner in bypass mode and take the KAT500 out of bypass and set to auto. I then use the xmit button on the K3 to create a tune signal to be sent to the KAT500. The K3 then shows a 1/1, the KAT500 about the same but the KPA500 which is in STBY mode shows around 3/1. What this causes to happen is the Amp will fault out if I try to use any power output. If I check the antenna with a trusted SWR meter I see 1.3/1 at the frequency of use.

As one those old farts, age 76 and a ham for 60 of them, I do still have all of my teeth, most of my hair and a 59-year-old fiancee. I guess I fail to understand the heartburn about calling frequencies. First, they aren't FCC assigned frequencies.? It is completely legal to operate on them on a first-come-first-served basis.? No one owns a frequency.? Now while it might be reasonably argued that it is bad form to occupy one continuously, it certainly isn't the end of the world. Regularly scheduled "nets" should certainly use a different frequency but if someone calls CQ and is answered by a distant station I fail to see a need to immediately QSY and risk losing the QSO, especially if it is MS.

Occasionally, when first turned on, it emitted a very loud medium pitched tone for a couple of seconds. Otherwise it seemed to operate normally. Now suddenly whenever it is turned on it emits this howl constantly, and no changes in settings affect this loud audio oscillation. Before I embark on the laborious process of taking it apart to start measuring every voltage, I was wondering if anyone has a clue to what failure might cause this problem so I can focus my investigation more efficiently?

I've built HP tube amps that required lots of air flow to live. See http://sadxa.org/n7ws.html for examples.? My thinking was that you could never have too much air.? That said, the blower noise was different in these from what my KPA500 emits.? In the 8877 amp for instance the blower IIRC, was rated at about 300 cfm.? But it operated into considerable back pressure from the inlet RF screen, the tube anode fins and the output grill.? Some of the noise was actually from the motor, not airflow.? Furthermore the amp was mounted in a 4' rack cabinet which further dampened noise.? It ran continuously and just became part of the background noise typical of a high power station and I lived with it. I don't have a KPA1500, just a KPA500 but I can say that at fan speed 5 or 6 it is way obnoxious.? In fact, just before writing this I went into the shack in the next room from the office and cycled the speeds.? My lady who is sitting in front of her computer here in the office asked, "What is all that noise?" I use a Yamaha CM500 headset at all times and I can say that a few nights ago when I operated as K7UGA and ran 300 Qs in 2 hours on 20 SSB the fan was pretty loud at times. Wes?

Testing I did was into a dummy load running CW and using the KPA1500 reported powers.? Ran K3s barefoot measuring the TX Sample level terminated with 50 ohms from 20 - 100W in 10W steps .? Then ran with KPA1500 operating up to about 1700W.? With the KPA1500 inline I ran the K3s from 5 W - 35W in 5W steps.? Max power reported at 35W was 1720W by the KPA1500.? Tuners in K3s and KPA1500 were bypassed in this data acquisition, the load was a Bird Termaline 1KW Dummy Load. TX Sample voltage is same with or without powering up the KPA1500, so pretty sure it is just a torroid with passive scaling. With the TX Sample terminated by 50 ohms I find?? POpep= (V^2)*55. Where V is the P-P TX Sample Voltage.? The constant 55 is from trying to do a linear regression.? Expect it is off a little based on accuracy of KPA1500 reported power and my scope has not been officially calibrated, but close. With an accurate RF voltmeter this could be refined by actually measuring power in dummy load but right now do not have the hardware to do that. Be interested if anyone has found a better fit. Be interesting to see what the manual reveals when they get caught up.

The release should be available in the next week or two. As noted by others, setting the minimum RF deck fan speed to 1 (or 2 if desired) also further delays going to higher fan speeds in TX. Also, since the RF deck is instant on, its OK to turn it off from the front panel when you are mostly listening and tuning the band. (The amp can also be set to power up in operate mode in its menu..) There are no limitations to turning it on and off frequently.

After feeling the first click, push them in further for the second click. We are finding some customers mistakenly think they are fully inserted after just the first click, which can lead to intermittent 50 V to the amp.

I would have thought the software would have kept the fans running even if you tried turn the amp off, until it had cooled down sufficiently. That's certainly the way my ACOM 2000 works and many other amps. - Paul From jperlick at ariacorp.com Sun Jun 3 02:29:40 2018 From: jperlick at ariacorp.com (John Perlick) Date: Sun, 3 Jun 2018 06:29:40 +0000 Subject: [Elecraft] KPA1500 Fan Noise Message-ID: Every amplifier has some level of fan noise. My new KPA1500 is seriously quieter than my former Expert 2KFA. My Henry 2K Ultra fans were so loud that I couldn't keep it in the radio room. Luckily I had the remote version. My Harris RF-3230 (all solid state) had 8 six-inch muffin fans! It sounded like a DC-9 warming up for a takeoff. I was two rooms away from the shack and I could still hear those fans! I run my KPA1500 at 1500 Watts SSB/CW and I have never heard the fans go past setting #2. If you want to run 1500 Watts of RTTY or AM, then expect the fans to be running hard to keep the amp cool. If you want a quieter shack, put the amp in another room.

I've had my KPA1500 (s/n 083) a few weeks and have enjoyed using it on the air, as well as subjecting it to IMD and other tests at a variety of power levels. Individual tolerance of acoustic noise varies and I put myself in the "sensitive" category. When I first set up the amplifier and power supply, I realised that I was going to have to do something more than simply stacking the units alongside my operating position: the PSU fan was just too annoying. Lacking any immediate "remote" options, I settled for putting the PSU on top of a small chest of drawers, located under my operating desk, which is made of thick, dense laminated particle board. The room is carpeted, and rather dead acoustically. I found that acoustically shielding the PSU helped enormously, while the chosen position still allows good airflow and access to the PSU. I did also experiment with some heavy felt drapes pinned under a section of the desk but, when the airflow to the PSU was good enough, there was no worthwhile improvement over just positioning the PSU under, and slightly towards the back, of the desk. As far as the RF deck fans go, I can live with the Level-1 speed but, in situations giving more than an occasional burst at Level 2, I'd be looking to locate the unit further from my desk. I do wear headphones from time to time, and that would certainly help with the acoustic noise issue, but it wouldn't be a long-term fix in my circumstances. The upside is that Australian power levels, and my operating modes, mean that the RF deck fans do not routinely get beyond Level 1. Even when doing the dummy load tests mentioned earlier, I paused the measurements if the fans hit Level 3. I'd add that the KPA1500 is likely one of a very small number of amplifiers of its class suitable for desk installation in my small shack. Notwithstanding my earlier comments about noise, I find it a nicely engineered product which meets my requirements for a high power, solid state gain block for use with a variety of exciters. My other amplifier is a Collins 30L-1 (4x811A), which now sits permanently attached to an S-line station. Fan noise was never a problem there, but 30L-1 cooling is less than generous, being helped by a single fan, the motor of which has aptly been described as a refugee from a record player. As an aside, I'm looking forward to the KPA1500 firmware upgrade, having also identified the occasional SWR bar graph errant excursion as most likely a firmware bug (aka algorithmic anomaly). 73 to all, Peter. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Don Butler Sent: Saturday, 2 June 2018 2:01 PM To: 'Richard Thorne' ; Elecraft at mailman.qth.net Subject: [Elecraft] KPA1500 Fan Noise Video posted In response to N5ZC?s request I just made this short video to provide a listen to the KPA1500's fans ... at least as they sound in my shack. Follow this link to view: https://vimeo.com/273064144 In addition to the KPA1500 the video also includes footage of my Alpha 9500 and Icom PA1 ? each running with their fans at maximum speed ? to provide a simple rather crude comparison. What do I think? I think that fan speed 1 and fan speed 2 on the KPA1500 are probably comparable to the fans that are installed on the other amplifiers as far as sound and efficiency are concerned and likely provide a similar degree of cooling at those speeds. And, I think that fan speeds 3, 4, and 5 (which are indeed noisy) provide the KPA1500 with enhanced cooling capability that is simply not available on other amplifiers.

This fan noise issue has me concerned to the point that I?m considering cancelling my order. While the amp won?t be on my operating desk, it will be on a rack next to my operating desk. Remoting the amp is not an option. Quite frankly I have no interest in remoting the amp. Is there anyone out there that has a KPA-1500 willing to post a YouTube video so we can hear the fan in action and judge the noise for ourselves? From the research I?ve done it appears that if you want a solid state amp, regardless of make, you need to be prepared for fan noise.

So far as I know there is only one reciprocating engine made for aircraft that has a water jacket. (There might be others nowadays - I haven't owned an airplane for some years.) The reasons others don't are reliability, safety, complexity, and - mostly - weight. Second, isn't this largely a contest-operating issue? I believe we are still governed by the rule that we may use only that amount of power necessary for the communication. I contest too, so I'll face the problem on those occasions, but not for casual ragchews. I plan to make some graphs of when in terms of time, power, mode and band the fans on mine kick up a notch, and use it as a general operating guideline if I need to. > > Ted, KN1CBR > > From billclarke at nycap.rr.com Sun Jun 3 09:17:10 2018 From: billclarke at nycap.rr.com (Bill) Date: Sun, 3 Jun 2018 09:17:10 -0400 Subject: [Elecraft] Compare: K3 to Collins S-line receiver Message-ID: <1eaecc43-f2c3-6da0-67d6-ae4b78d2c3d4@nycap.rr.com> Discounting the digital capabilities such as memories, DSP, etc. and only considering actual signal reception: I have had S-lines in the past (dark dim past), so certainly am familier with them.

Message-ID: Just received SN 209 yesterday. Ordered late Oct 2017. Removed the KPA500 and put the big boy into place, using the same KPA cable to the K3. The K3 controls the amp and the amp band switches the K3, like it should. With between 30 and 40 watts drive I get full power out... except for the following: On 15 meters, I get less that 50w out. If I increase the drive pwr the 1500 goes into fault mode. On 20m, I have to increase the drive to 50w to get 900w out, then the amp goes into fault mode. On 17m, I have to increase the drive to 40w to get 150w from the amp, then fault mode. All other bands work fine, The amp ATU is bypassed, and the results are similar into a dummy load or a well matched antenna. The ATU in the K3 in bypassed. I have not changed any K3 settings since I pulled the KPA500 and plugged in the 1500. Also, when I tried to reset the amp as per the manual, (Hold edit when tapping the on button) nothing resets to factory defaults. I tested this by lowering the display brightness and contrast, and after the reset attempt, my dim settings did not change. I also downloaded and reloaded the firmware ver 1.4 from Elecraft, and reset it to factory defaults. Any ideas? Is this another case of equipment superior to operator?

If you want it, email me DIRECT, NOT ON THE LIST, and I can send it to you. It uses no more resources than any other cluster client, so it can work on many clusters. The script has more comments than actual code, so it is readable. You will need to change things to match your directory structure, and a few other items as well, but once working it is actually pretty reliable. The script scrapes my DX Cluster, and when if is sees "trigger number" of DX stations spotting US stations from zones 3, 4, or 5, for selected bands, it increments a counter for each zone and band. Once a "time period" it checks the increment counters to see what the count is for a selected zone, and band, and if the count is larger than a programmable trigger, if so, it announces that whatever band exceeded the trigger is open using an MP3 file. It actually works quite well. I am in the process of changing it to not look at zone, but grid squares to better localize it. Anyway, if you want a copy you are welcome to it, but please send email to me NOT TO THE LIST. I am out of town now, so it will be a few days before I respond.

So just to be sure I make a new set of RF jumper cables out of LMR-240. Hooked everything up and the problem is now fixed.

I leave my K3 here for remote use and use the amp at my winter home in Florida to use with my Flex 6500 with a Steppir Vertical antenna without the KAT500 tuner. When I got up here I installed the KIO3B option. The install went well with no issues, all looked good so I connected the K3, P3, KAT500, and KPA500 with the Elecraft provided cable set like I do every year. The issue I'm having is an SWR difference between the KAT500 and the K3. For example if I use the K3's internal tuner I can on a chosen frequency achieve an SWR of 1/1. I the put the internal K3 tuner in bypass mode and take the KAT500 out of bypass and set to auto. I then use the xmit button on the K3 to create a tune signal to be sent to the KAT500. The K3 then shows a 1/1, the KAT500 about the same but the KPA500 which is in STBY mode shows around 3/1. What this causes to happen is the Amp will fault out if I try to use any power output. If I check the antenna with a trusted SWR meter I see 1.3/1 at the frequency of use. I upgraded the firmware in all the devices in use, I also did a reset of the KAT's stored frequencies memory, and checked both the amp and tuner with the utility programs. I'm going to call Elecraft on Monday, anyone have any ideas in the meantime I can try? 73 Jeff kb2m ______________________________________________________________ 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 kb2m at arrl.net From n6kr at elecraft.com Sun Jun 3 12:19:47 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 3 Jun 2018 09:19:47 -0700 Subject: [Elecraft] FT-8 vs. PSK31: an enlightening Sunday morning field report Message-ID: <7AD2FB51-E216-40F5-B993-A9870141E595@elecraft.com> Thanks, everyone, for all the pragmatic and philosophical observations about FT-8. Depending on who you ask, it?s anywhere from miraculous to take-it-or-leave-it. Or both. This is characteristic of many aspects of amateur radio, of course. To each their own. A different sub-noise-floor mode, PSK31, was on my mind this morning. After breakfast I grabbed my KX2 and 17/20 meter whip and went outside to check the bands. All of the CW signals were weak at the time. Then I happened across a warbling PSK31 signal in this mode?s preferred segment (14070-14073)?a VA7 calling CQ. I used the KX2?s auto-spot function, resulting in perfect copy. He came back to me on the first call at 10 W, which is not unusual; PSK31 has an established track record as a great QRP more. The important point is that I was able to carry on a satisfying, non-automated, data-mode QSO using a only a hand-held radio with an attached keyer paddle. In my sweats. On a gorgeous day right out of a Maxfield Parrish painting. Without a computer. I was reminded that PSK31 *is* that mystical unicorn: the sub-noise-floor data mode that?s also a conversational mode. It isn?t full QSK, like CW, and it lacks the rigor of FT-8, but it has some of the advantages of both. This is why PSK31 (and PSK63) are built into the K3, K3S, KX3, and KX2. All you need is a keyer paddle. If you prefer a keyboard, you can use a terminal emulator application running on a variety of devices. Just attach your device to the rig using the supplied USB cable. To summarize: If you?re a CW op who?s temporarily out of CW signals, or an FT-8 user who longs for a few unmediated QSOs, take a walk on the wild side and try PSK. Notes: 1. Elecraft radios have a special mode, ?PSK-D?, that treats PSK31/63 as a narrowband mode for VFO tuning purposes. You don?t just park the VFO at 14070 like you do when using a sound card and a computer. Instead, use a very narrow filter bandwidth (50 to 100 Hz) and tune around the 3 kHz PSK segment using the VFO set to 1-Hz steps. When you find a signal, tap the keyer speed knob, which auto-tunes the received signal (this is the ?SPT? function). 2. RTTY mode (FSK-D) is also available. This legacy mode is great fun during RTTY contests. Last year at FD, taking a break from CW, I made over a dozen RTTY contacts using the KX2, including one of over 2500 miles with the rig hand-held + whip. 73, Wayne N6KR ---- http://www.elecraft.com From lee.hiers at gmail.com Sun Jun 3 12:39:36 2018 From: lee.hiers at gmail.com (Lee Hiers) Date: Sun, 3 Jun 2018 12:39:36 -0400 Subject: [Elecraft] [KX3] FT-8 vs. PSK31: an enlightening Sunday morning field report In-Reply-To: <7AD2FB51-E216-40F5-B993-A9870141E595@elecraft.com> References: <7AD2FB51-E216-40F5-B993-A9870141E595@elecraft.com> Message-ID: Yet i still can't copy it by ear....still just noise.

I pick up so much sqawks and buzzing weird interference, grating machine sounds, on my KX3 on all HF bands, it is horrible in my setting (ground floor apartment in the city). I have the same issues on 2 meter handhelds, noise all over the band, trips the squelch making it nigh impossible to scan without the radio stopping on some ghost signal that is only intermod. Same story with the KX3 2 mtr module though I can turn the squelch up enough to keep the radio scanning without stopping on noise for the most part. Is there any hope for HF? Would some sort of HF band pass filter help my KX3? Or is the filtering in the KX3 already good enough? I can't make it go away with the built in KX3 noise filters. There is this one company across the street from me, some internet megalith place with sat dishes on the roof and I wonder if some of the noise is coming from that establishment. Anyway... thanks for any ideas... head for a park, a mountain peak... I know... :) 73's Mike AB7RU DN17gp From n6kr at elecraft.com Sun Jun 3 13:13:24 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 3 Jun 2018 10:13:24 -0700 Subject: [Elecraft] Intermod filter for the KX3 In-Reply-To: References: Message-ID: <63E14232-B0A0-46F9-AED3-EA0C8F16D673@elecraft.com> Mike, What you?re describing sounds like noise that is in-band and would be debilitating for any radio. Not intermod. But just to be sure, set MENU:RX SHFT to 8.0 and turn off the noise blanker. This is the most resilient setup if you have monster signals actually causing IMD. Also try turning off the preamp. If the above steps don?t help, you could simply have a case of very high noise floor. Here are a few more things you can try: 1. Use very narrow filter bandwidths. In CW mode, use the APF feature (audio peaking filter). 2. Move the antenna farther from identified noise sources. 3. Try a magnetic loop. These are very narrow banded, and may have directional characteristics you can make use of. If all else fails, try taking your KX3 portable as an experiment. A location far from massive noise sources can be a breath of fresh air, both atmospherically and ion-ically. It?s not a long-term solution unless, like me, you discover that field operation is a blast. But it?ll give you some perspective about your noise at home. 73, Wayne N6KR ---- http://www.elecraft.com > On Jun 3, 2018, at 9:49 AM, Mike Parkes wrote: > > Hey group > I have an issue here and am wondering if a good band pass filter would > help?

You'd ALMOST HAVE to cool the copper heat spreader, since the LDMOS are I suspect soldered to it.? Don't know if the heat spreader is soldered or mechanically attached to the heat sink..? It is possible that you could gang multiple large OTS CPU coolers onto the heat spreader in place of the massive heatsink. Then you'd need to figure out what you were going to do with the 1- "n" number of sets of hoses and radiators.... and 1-3 times n number of radiators in very large fans. And THEN, remember that there are other thermal loads inside the chassis...? You'll still need to provided some airflow to those loads, so you'll still need case fans. Certainly and interesting and intriguing project for someone deep of pockets and most grande of huevos....? but not a trivial task certainly. I personally would not risk my $6k amp to do it...

I have one external power supply from a well-known ham-gear manufacturer of somewhat questionable repute which throws off S9 racket all over everything, or did until I gave the output cord about 10 turns through a hefty ferrite. I'd forgotten about the RX Shift feature being per-band somehow... it could be my imagination but it seems to take down the omnipresent 30Hz impulse noise a few dB at my QTH in San Mateo. (I've of course gone through turning off power to the house and driving around in portable operation... I think the problem is generally being anywhere near PG&E transmission lines, which is something that's hard to avoid anywhere in the SF peninsula. The noise blanker also does a pretty decent job of suppressing it even further.) Nick On 3 June 2018 at 10:45, Mel Farrer via Elecraft wrote: > Wayne, > You missed one.

Sherwood has made distortion measurements on many many receivers. As you see on his website, the K3 is far far better than the S-Line. The key measurements are dynamic range measurements?particularly with nearby signals. The radio is limited at the low end by its noise floor (and because HF is so noisy you really done need super low noise floor). But at the high end, the receiver is limited by distortion and blocking. The K3 and, interestingly the KX3, are near the top of the list. Far better than the old Collins rigs. I think what happens is we remember back in the 1960s when there were far fewer hams and that old 75A4 really sounded great! I fully agree?these radios did sound great! But today there are twice as many hams crammed into the same bands and is can be really tough for receivers to discriminate without distorting. If you want to see what I mean, try using your 75S3C during a busy contest then switch to a K3. As far as birdies, most radios have birdies. Modern radios are so sensitive and selective that they can pick up the digital modem two houses away on 6? of wire. We live in a digital world and there are noise sources everywhere! Even in the K3. I had birdies in my Icom 781, my WJ 8711?s and my K3. They were/are all below the atmospheric noise level. Never a problem! My PL noise was far worse. Good topic, Bill!

Message-ID: <1528059209888-0.post@n2.nabble.com> Hi, Very recently there was the same question asked about the K1. I don't recall any mention of this topic on the K3 on the reflector. It has internal trimmers on the per ham band HF filter. Is it advisable to occasionally touch these up? I have no reason to believe that my oldest K3 (ser#82) is out of alignment, but I'd like to be ahead of the game. I am old enough to have used tube rigs in my early ham career and they definitely needed occasional tune up. The narrow band ham band RF filters in the K3 have relatively high Q so the slightest component drift will quickly affect the shape of the filter curve. If the answer is affirmative, could we get a procedure for doing it properly? Tuning for max signal at the center frequency may not produce the proper shape of the bandpass filter (flat top for the required bandwidth). I know from my previous career as an RF engineer that tuning LC bandpass filters can be tricky.

The **most** critical adjustments on every tuned circuit of the K1 filter boards are made to peak transmitter output. These adjustments are far more critical than any for receiver performance. This means that the first sign of a need for filter board re-alignment is the inability to obtain 6 to 7 watts output on each band when the DC supply is about 14 vdc. If you are getting good power output on each band, then there is **nothing** to be gained for either transmit or receive performance by re-alignment. The only problems with drifting K1 alignment occurred with very early (2001-era) KFL1-4 four-band filter boards. The original white-body tuning-adjustment capacitors were found to drift eith temperature change, which had great effect on the KFL1-4 sharply-peaked LC-circuits. By 2002 superior new blue-body capacitors were supplied with with new KFL1-4 kits and also made available for back-fit in existing KFL1-4 boards. I installed the back-fit and that permanently solved the problem. The L-tuned KFL1-2 two-band boards never had the problem, but the circuits of the KFL1-2 are not as sharp as those of the KFL1-4 either.

There probably aren?t more than a handful of people on the reflector that have the necessary equipment and expertise to do it themselves. And that would mean that Elecraft would get every K3/s back periodically for routine adjustment. Doesn?t seem reasonable at all. Tuning at the ?center? will NOT produce a proper shape, guaranteed. And peaking the lower and upper pass frequencies aren?t likely to get it ?flat? either. It?s not exceptionally difficult, but you have to know what you?re doing AND have the proper (good) lab equipment. Most don?t, on either count. I suspect putting out instructions for a DIY approach to this would be a disaster waiting to happen, given the typical ham shack penchant for ?tightening all the screws? :-) Grant NQ5T K3 #2091, KX3 #8342 > > [The K3} has internal > trimmers on the per ham band HF filter.

In-Reply-To: References: Message-ID: Doug, The answer is "maybe". If all is working fine and you have good power output, then I would suggest 'leave it alone'. In any case, you will only have to peak the bandpass filters on the band board(s) very slightly with a TUNE at a power level between 1.5 and 2 watts. Make certain it has been powered on for at least 1/2 hour before aligning to allow things to come up to temperature. You do not have to do the receive alignment of the bandpass filters first unless you have changed a band on the band board. If you have the KNB1 installed, you will want to peak its trimmer capacitor for a maximum response in receive mode. After aligning the bandpass filters, you can proceed to the BFO frequency (set it to center the FL3 passband at your desired sidetone pitch), and set the Transmit Offset to the same pitch. You might also want to check the frequency of the VFO when the VFO knob is turned full counterclockwise, and also do the CAL OPF to get the VFO Display on frequency just in case the crystals on the band board have drifted over time. If you are having a severe receive or transmit problem, then you may want to resort to Receive Signal Tracing or Transmit Signal Tracing to find the troublesome stage, but that is not usually necessary except in problem cases. 73, Don W3FPR On 6/3/2018 2:36 PM, Douglas Hagerman wrote: > I have a K1 that I built several years ago.

Have you measured the receiver MDS and found it to be lacking from the last time you measured it? If the answer to both those questions is "NO", then the answer is that it does not need any alignment. Older tube rigs may be a different matter, but modern components are not as prone to value changes with age as they were "back then". This applies to any transceiver, and is not particular to the K3 or any other one transceiver. I have serviced K1s and K2s K2s that I had fully aligned and calibrated several years before, and find them still in perfect alignment (although I do go through the alignment procedures on those I service again just as a check). Unless you have adequate instrumentation, I would not attempt it. It would be simpler to send your K3(S) back to Elecraft than to attempt it yourself - by the time you obtain adequate instrumentation, you will spend more money on the project than a trip to Elecraft. Then you mention the other problem - lack of full instructions. Those are not available for the K3(S). Elecraft has automated testing lines set up to do that job. 73, Don W3FPR On 6/3/2018 4:53 PM, ab2tc wrote: > Hi, > > Very recently there was the same question asked about the K1.

I do not repair Elecraft radios. In fact within the past year I've stopped repairing all radios........except mine.?? And in my case, I've sent my K3S back to Elecraft to repair.

I really don't have the necessary items and tools to work in detail with surface mount components and the technology, extender boards, test fixtures and such items as used today.?? As to alignments, these are usually required but only after a component failure and thus it has been replaced. So to answer your question; "If you encounter a misaligned K3 in your repair activities, how do you fix it?"?? My answer:? I'd obtain a RA from Elecraft and sent it to them.?? What ever it cost, is what it cost. Present door to door turn-a-round time to Elecraft for repair is some 10 to 20 days plus transportation.??

I personally think that is an unfair suggestion. Fan noise with this amplifier is NOT an issue to me. I have made previous comments and have also posted a video on this thread, and if I have given the impression that fan noise is a problem in my shack I apologize, because that is simply not the case. Quite frankly, I think all the hubbub about KPA1500 fan noise is a huge overreaction. The reality is that the fans will NEVER be required in most operating situations. I've had my amplifier for three months now, and it has gotten many hours of use. Typically, with the amp idling in standby as I tune and complete occasional short CW QSOs, the fans NEVER do kick on. And if they do they will rarely rise above Level 2. Levels 3, 4 and 5 may be required during very heavy duty only, and, at least at my station, I cannot foresee that happening more than 1 or 2 percent of the time. I have manually selected level 3 on just two occasions, and have never had to use levels 4 or 5. I personally believe that folks out there are fretting over fan noise that may never occur. IMHO the KPA1500 is a great amp. Amps are going to get hot. The more an amp is put into transmit mode the hotter it's going to get. So it has to be cooled. There's no free lunch. When my amp does get hot enough to require speed level 3 or above I will simply put on my earphones and continue to operate (I use earphones most of the time anyhow). As I mentioned above, in the three months that I have owned this amplifier, I have manually switched to level 3 just two times (once while CQing for hours while running in a CW contest and once when I spent about 30 minutes chasing a DX station in a major CW pileup). To me, increased fan cooling capability is one of the KPA1500's uniquely great features. Yes, the fans create noise, but they also rapidly cool the heat sink (probably better than any other amplifier out there). But folks seem to be more concerned about this noise thing when (I think) they should really be appreciating the KPA1500's superior cooling capabilities. I think we should get over this fixation on noise and just enjoy our amplifiers. As far as I'm concerned fan noise is NOT as issue with the KPA1500.

In each case, I'm reading the power output on the KPA1500 display, but it appears consistent with the P3 TX monitor.? Any ideas?

In-Reply-To: References: Message-ID: <2E489689-049F-4367-8DF2-C509028D3BD1@elecraft.com> If you HOLD the ATU TUNE button, you switch the ATU between IN and BYPASS. When you tap ATU tune, and provide some RF from the exciter, the ATU searches for a match. If the SWR of the antenna is good enough without ATU reactances, the ATU discovers that the best tuning solution for that frequency is ?bypassed?. And when that happens, both ATU LEDS are illuminated. If you tune further up or down the band, and your antenna SWR is above 1.2, the ATU will insert reactances and if it does, the ATU BYP LED is not illuminated. 73 de Dick, K6KR > On Jun 3, 2018, at 18:06, Bill Hassan wrote: > > I was noticing that when I hold the ATU TUNE/ATU MODE button, the BYPASS > led above it always stays on. > The IN led will switch on and off as I hold the button a second time, but > the bypass led will always remains on. > I don't hear any relays latch. > > This happens on all bands, except for 30m. > > On 30m, holding in the button, releasing it and holding it again will turn > on the IN led, and then the BYPASS led. > I can hear the relays latch into place as it goes from in to bypass to in... > > On all bands tapping the button will put the amp into tune mode.

If this the case, use of noise reduction or noise blanking in the KX3 will likely make the issue worse, not better. ? ? One test is to use a step attenuator between the antenna and the receiver input.? Thus selecting some value of attenuation for all signals, thus equally reducing the 2 or more out of band signals.? If this improves your issues with regard to the interference, one can attribute to strong signals mixing and entering the receiver.? A band pass filter will likely help and allow you to transmit on that band as well as receive on that band.?? A band pass filter will be required for each band you intend to operate.?? A full set, they aren't cheap. Likewise on 2M, many paging and public service systems are now transmitting digital data streams.? These cause me havoc on 2M as I am 600 ft from the local 911 communications tower.? Only 12 total of antennas, VHF and UHF,? on that tower.?? A band reject or notch filter corrects the issue.?? But again, one needs to know the exact frequencies of the signals which are causing the interference as that is the frequency the notch must be applied. I use a filter from PAR Electronics which is a notch filter.? The insertion loss on 2M is very low allowing me to receive and transmit with the filter in the line between the radio and the antenna but provides about a 40 dB notch at the offending frequency. ? ? In general handheld radios do not have adequate space internally to design in and implement good front end filters.?? They in general are very subject to interference and do not perform well with RF from nearby services operating above or below the ham bands. If the interference is in the pass band of the receiver, finding and eliminating the source is the optimum approach.? If the mixing components are in the PA of a transmitter and thus being radiated and picked up by your receiver, finding the source is about the only solution.?? This could be the product of 2 FM stations in the building or a building of close proximity.?? As an example, 99.5 MHz and 106.7 MHz mixed together produce two signals being a sum and a difference.? The difference is 7.2 MHz.....smack in the 40M band. ? Probably due to harmonics affect 20M and 15M to some extent. ? Depending on exactly where the mixing is taking place, a corroded pipe on or in the building, in the PA of one of the transmitters, or some other device which becomes non linear when excited with RF, then it radiates the signal.? Finding and correcting the issue is about the only solution. Third choice.............move.???? Which in fact might be easier.?? Just be sure one doesn't move into an RF plagued area. 73 Bob, K4TAX On Jun 3, 2018, at 12:49 PM, Mike Parkes wrote: >> Hey group >> I have an issue here and am wondering if a good band pass filter would >> help?

What it is is a venturi pressurized by a bladed fan in the base. In this way it is trading high-pressure low-velocity for low-pressure high-velocity which is appropriate for a fan in free-air to cool human bodies.? Fans designed to push air through heatsink fins are designed for moderate to high back-pressure depending on fin density and height. When we modeled our convective heatsinks for the KX2 & KX3, we also did designs with fans (and brought some to Dayton).? After iterating a heatsink design in ThermalCAD for hours to get the last percent more convective cooling, it is sobering and amazing how much heat you can remove by forcing air to remove the stagnant boundary layer of air from the heatsink.? It makes you realize natural convection is a very weak motor for air movement. A tube amp can potentially be quieter than a solid state unit due to the fact that the total heat removal in BTUs is directly proportional to the temperature differential between the air and the object being cooled (Newton's Law of Cooling). Analyzing the thermal path in each situation; the anode fins of a common 3CX or 4CX series tube are directly cooled by the air and can run at 250?C, whereas the transistor has some additional series thermal resistances to overcome before meeting the cooling air which can reduce the effective heatsink temperature at FET max junction temperature and heat flux to 125?C.? Assuming 25?C air, there can be a 225?C differential between air and tube anode, and a 100?C differential between the FET heatsink and air.? This means for any given volume of air passing through the two devices, there can be 2.25 times as many BTUs removed from a tube.? The other issue is the fact that the ceramic tube fins are designed for high pressure low-volume cooling, and most non-ducted FET heatsinks are designed for lower pressure, higher volume air flow. High-velocity fans typically create more noise than do higher pressure fans due to the relatively slower air movement and lower turbulence past the fins.? This being said I have used some really noisy tube amps. I opt for an Elecraft KPA amp for many reasons; the fantastic K-Line integration, included ATU (in the 1500) and protection circuitry they design in.? I use a KPA500 which also can get loud, but I appreciate what it takes to remove 500 W of heat to keep a 500 W amp cool (assuming ~50% efficiency).? Based on the reliability of the KPA500, I also do not think there is a tube amp on the market which protects it's devices as well as Elecraft does their FETs.? In order to address the noise issue, perhaps a remote control like the Acom 2000A offers is a good option for the KPA1500 at this point? I was not paid to make this endorsement, just a happy customer.

Without wanting to comment on the likely reasons I will say that in some situations, typically non-intensive, good signal level conditions, the 75S3B here with a 312B4 console and that big 6x4 speaker does have a certain magical sound quality, even with the 2.1 mechanical filter. The rigs are on separate desks and not operated at the same time. I think I could be tempted to pull the S3 receiver and run it with the K3 side by side and see how it plays. Although I have 1.5kHz and 500Hz filters in the S3 it's not such a hotshot CW receiver, especially not having the correct bfo offset crystal which means using the variable bfo. The S3 notch filter is nothing special I feel and of course it lacks all the other great benefits that the K3 has. The 2 things I really like on the S3 are the sound and the tuning rate, I've never been able to replicate either with the K3. Putting the 312B4 speaker on the K3 might be a good start though.

I am stuck at #327 to achieve the bottom rung of the Honor Roll, so these past few months have been more than boring since the 3Y0Z situation. A ham friend of mine, Jim N5JS, told me about WSJT-X FT8 and I begrudging downloaded the software. Well, after getting the K3 plugged into the computer, I had the setup up and going. After a few days of ho-hum watching my computer work stations, I wondered when the next dxpedition was going to be on the air! In talking to Jim earlier, he pointed me to pskreporter.info. After awhile of playing with seeing who was hearing my signal across the globe, an Uzbekistan station was spotted on 20 meters earlier! One that I need, since my old DX contacts of the '70s never qsl'd me for the 5 Uzbekistan stations I had worked. I quickly made a sked with UK9AA via e-mail and in 2 days, 20M was wide open one night! Bingo, UK9AA answered my directed CQ and was quickly in the log. The card is on its way! All with 50 watts! I have a better appreciation of FT8 now, but still long to be in the crowd up 5-10 KHz working a weak "CW" DX station! ----- Roger W5RDW -- Sent from: http://elecraft.365791.n2.nabble.com/ From donwilh at embarqmail.com Mon Jun 4 09:57:46 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 4 Jun 2018 09:57:46 -0400 Subject: [Elecraft] Compare: K3 to Collins S-line receiver In-Reply-To: References: <1eaecc43-f2c3-6da0-67d6-ae4b78d2c3d4@nycap.rr.com> <005a01d3fb46$5d27d390$17777ab0$@kh-translation.dk> Message-ID: Henry, I believe you will find the arguments similar to those among audiophiles when recorded music was changing from vinyl to CDs. My take on the subject is that the dynamic range of the digital techniques exceeded the analog by a wide range you will not be able to discern the microprocessor noise at normal or even very high listening levels. Take a look at the dynamic range and MDS of modern hybrid (like the K3/K3S) receivers or good SDR receivers (like KX3 or KX2), in comparison to some of the best analog receivers, and you should find that the dynamic range is much greater (indicating its resistance to overload and distortion is greater). That increased dynamic range gives rise to a better MDS - in other words, it can hear weaker signals. The mathematics in the DSP code is not going to cause distortion unless the ADC is overloaded with a strong signal (good design says that should not happen). The Sherwood listings will verify what I am saying - yes, there are several analog tube-type radios in the Sherwood listing, but they are pretty far down the list. Any microprocessor noise should only be introduced in the audio section, and with good design, that should not happen either - oh yes, if you have very good ears, you might be able to hear some at a very low level if you turn the AF gain up all the way, but that is not a normal condition. If your ears feel that the tube audio gear is "warmer" than the solid state stuff, then consider that the tube gear generates some 2nd and 3rd order distortion which is normally what makes it sound "warmer". There are devices available for solid state audio which add a bit of that "warming sound" to better satisfy the ears of those who like to hear it. Certainly, the large speaker enclosures used with old tube-type radios sound much better than the small speakers in compact solid state radios, so please don't compare based on those speakers. Connect a good quality audio system to both radios if you want to make a comparison of that sort. 73, Don W3FPR On 6/4/2018 8:49 AM, Henry Pollock - K4TMC wrote: > Yes, I would like to here what others can add to this thread.

The secret to using the zero-beat method for the Reference Oscillator is in the ability to correctly tune WWV (or other standard station) to zero-beat. I make use of an audio spectrum analyzer running with my PC and soundcard. Spectrum Lab will do fine, but I use Spectrogram v16. For those who want Spectrogram 16 or 5.17, they are available on my website www.w3fpr.com - scroll down near the bottom of the opening page and you will find the links. Those files are local to my website and have been scrubbed many times for virus. With Spectrogram running, first tune WWV and feed the K3 audio to the soundcard input using SSB mode. Knowing that WWV transmits 500 and 600 Hz tones with a 1 second 1kHz tone at the start of each minute, it is easy to properly tune WWV (in SSB mode). Now switch the K3 to CW mode, and you should see the carrier displayed at your sidetone pitch on the Spectrogram screen. Adjust the tuning slightly if not true. Now that WWV (or other standard station) is tuned properly, lock the VFO and follow the other instructions in the Zero-Beat (Method 2) in the manual. All done. 73, Don W3FPR On 6/4/2018 12:32 AM, Clay Autery wrote: > It was not until recently that I acquired the TMP connectors and crimp > tool to make a proper jumper cable from my K3s' J1 connector on my K3s? > TXCO (TMP) to my frequency counter (BNC), so I have always used the > "zero-beat" method.?

I recently sold my S-Line that had a 75S3C receiver in it and I?ve owned two K3?s and now a KX3 and KX2. I gotta admit that the tube audio was much more pleasant to listen to as compared to the solid state rigs. Can?t exactly say what the differences are but the tube audio sounded much ?fuller and rounder? that the solid state gear. Don?t know if that poor description helps, but there it is. 73, Joe W2KJ > On Jun 4, 2018, at 8:49 AM, Henry Pollock - K4TMC wrote: > > Yes, I would like to here what others can add to this thread.

Well, it really isn't nearly as "complex" as it may look/read. The complexity is largely "self-inflicted" due to: a) the inclusion of a number of steps that for "normal" (aka: non-OCD) folks are OPTIONAL, b) my tendency to use 10 words when 2 will suffice, and c) the inclusion of many "beginner" button/dial instructions that most K3 ops wouldn't need. I wrote that specific procedure to amplify what the manual says about "Method 2", and for use without any external instruments/devices.? I even wrote it to exclude more than a passing mention of the P3, which can be used to great assistance IMHO. While using Spectogram is certainly an option, I would prefer not to insert anymore uncalibrated devices/items into the signal path than necessary. If I were going to use an external instrument, I'd just hook it up to the HP5335a counter or the VNA.? Most folks don't have these things. Perhaps a second draft noting which steps are, strictly speaking, "optional, and an abbreviated section that excludes all of the "beginner" instructions for "Tap", "Hold" and button and dial callouts. That would make the text a great deal less daunting. Thanks for the feedback! 73, ______________________ Clay Autery, KY5G (318) 518-1389 On 06/04/18 09:31, Don Wilhelm wrote: > Clay and all, > > That is good work, but I feel it is overly complex. > > The secret to using the zero-beat method for the Reference Oscillator > is in the ability to correctly tune WWV (or other standard station) to > zero-beat. > > I make use of an audio spectrum analyzer running with my PC and > soundcard.?

It's quite helpful. For those of you that don't think that fan noise is a potential problem, you need to understand my point of view on this. I've tried very hard to get a good clean noise free signal to my speaker or head phones..? This starts with a good antenna system followed by a good ground system and chokes as needed to reduce any induced noise into the system.? i still have work do in this area. It doesn't make much sense to get the above done, only to have the audio portion of the signal interfered with. So before I lay down significant $ for another device, I want to find out all the pro's and con's for that device so I don't later regret the decision. In my case I'm not interested in getting a set of headphones (that includes a boom mic) that clamps on to my head that causes discomfort.? If I'm going to use a set of headphones it will continue to be the Yamaha CM-500.? The mic is outstanding and it's the most comfortable headset I've ever used.? I use the headset for cw and ssb, but I prefer to use my external speakers for RTTY with the volume low. While I'm not all that interested in remoting the amp, I may end up going this direction.? I have the room to build a sound proofing wall that can be located between my operating desk and external wall to the shack where my entrance panel is.? This may be a good option, if needed, in order to have a quality piece of equipment in my shack. I've spent time on my antenna system to mitigate noise, I may have to do the same thing on the audio side. So the folks who don't mind the extra fan noise (if in deed it exists) fine, but understand where some of us are coming from that don't want to deal with the noise (if in deed it exists). At this time I'm still looking forward to taking delivery of the KPA-1500 in the very near future.

Musically pleasing to our ears is the difference between an audio signal containing 2nd or even order harmonics vs. a signal containing 3rd or odd order harmonics. Even harmonics (i.e., second order harmonics) are considered to sound fat and warm, although they can be muddy and soft sounding as well. Odd harmonics (i.e., third order harmonics) are considered harsher and edgier sounding.? A pure square wave gives only odd harmonics.? A pure sawtooth wave gives both even and odd harmonics.? A pure sine wave has no harmonics other than the fundamental.

An Orchestra sat behind a curtain. Between the curtain and the orchestra was a physical acoustic filter that had the bandpass of a typical AM radio/speaker of the day. The filter could be switched in or out. The audience said the limited bandpass sounded more natural. This was attributed to people being used to the sound of the radio but not a live orchestra. Those of us who grew up with the Collins/National/Hammarlund tube gear probably had our standard of how receivers should sound established by those units. The memory of the sights, smells, and sounds of our youth are with us forever.

I actually do like the idea of liquid cooling since it's efficient and flexible if designed properly, but it uses much more space ... the liquid tubes alone guarantee that and if you want quiet the radiator is much larger.? I don't think that weight is the real issue here ... space certainly is, though.? Liquid cooling for the KPA1500 would be unrealistic on a commercial basis for a small amp. But if you extract the heat via liquid cooling and transfer it to a large enough fan-cooled heat dissipator with larger and slower running fans, you can make the noise almost imperceptible.? I have liquid CPU cooling on my desktop computer and I can't even hear the two CPU fans over the relatively quiet case and power supply fans. 73, Dave??

It has an external fan on the rear of the chassis, and the floating blower inside the chassis. I had not until today realized that the fan on the back is the external fan recommended for RTTY use - it came that way and I don?t recall paying a premium for it. Regarding the fan speed selector switch, my alpha 87a does not have this switch. The internal blower and the external fan run all the time. The external fan is mounted in a location that suggests it is for cooling the power supply, and it is recommended for use on 50 Hz mains power. If there is a different variant of the 87a without the external fan, it may be 4 dB quieter than mine as was observed for the alpha 89. 73, Bob R From n7wy at rocketmail.com Mon Jun 4 13:08:11 2018 From: n7wy at rocketmail.com (n7wy at rocketmail.com) Date: Mon, 4 Jun 2018 17:08:11 +0000 Subject: [Elecraft] =?utf-8?q?Compare=3A_K3_to_Collins_S-line_receiver?= Message-ID: Rob Sherwood?s tables show that the 75S3B has about the lowest MDS of any receiver ever made. The dancing 75S3B analog signal strength meter needle is more appealing to me than a row of LCD indicator segments. The 75S3B tuning rate is pretty high compared to the K3(s). Tubes can be found, but it takes effort. The 75S3B first IF is very wide so all the selectivity is imposed by the mechanical filters in the 455 KHz IF. Thus, signals that can form IMD products are present at the 2nd mixer. Probably one reason for the 75S3B?s lower IMD performance. Rob Sherwood?s papers show that the 32S3B transmitter has very low 2-tone IMD compared with most of the recent TX that use solid state drivers and finals. Yes, I did have an S-Line station for 15 years, but now it is K-Line. 73, Bob Rennard - N7WY From Hamshack at N4ST.com Mon Jun 4 13:16:28 2018 From: Hamshack at N4ST.com (Jim - N4ST) Date: Mon, 4 Jun 2018 13:16:28 -0400 Subject: [Elecraft] Compare: K3 to Collins S-line receiver In-Reply-To: <004501d3fc1b$ad60b8b0$08222a10$@erols.com> References: <1eaecc43-f2c3-6da0-67d6-ae4b78d2c3d4@nycap.rr.com> <005a01d3fb46$5d27d390$17777ab0$@kh-translation.dk> <004501d3fc1b$ad60b8b0$08222a10$@erols.com> Message-ID: <015301d3fc27$cac5c880$60515980$@N4ST.com> Love my K3S and certainly wouldn't trade it.

Indeed, the first place to put absorptive material is on wall surfaces around the amp, treating other wall surfaces can also help a lot. Hard surfaces contain the sound, causing it to bounce around the room. Soft surfaces absorb the sound, causing it to die out more quickly. Mechanical coupling of vibration to the desk increases the audibility of noise, so it can also help to isolate the amp from the shelf it is sitting on. Fan noise on the transmitted signal can be minimized in several ways, all of which are pretty simple. First, keep the mic close to your mouth -- sound falls off by 6dB per doubling of distance. Boom mics, like the CM500, are great for this. For best sound quality, I try to keep the mic an inch or two above and to the side of my mouth. The principle is to maximize speech and minimize noise -- a simple signal to noise problem. Second, don't turn mic gain up higher than needed, and don't overdo compression. This is the primary cause of excessive noise on transmitted signals. Third, set TXEQ to emphasize the speech range and de-emphasize other sound. My guideline EQ settings do this -- max cut of the three lower bands, 6 dB cut of the fourth band (400 Hz), and then get reports from a careful listener. 73, Jim K9YC From callen.baker at yahoo.com Mon Jun 4 14:38:02 2018 From: callen.baker at yahoo.com (C Allen Baker) Date: Mon, 4 Jun 2018 18:38:02 +0000 (UTC) Subject: [Elecraft] Fan Code References: <888001325.2019380.1528137482703.ref@mail.yahoo.com> Message-ID: <888001325.2019380.1528137482703@mail.yahoo.com> I opened the windows in my shack and inserted a key into the fan power line.

Those of olden tymes, recall the fanless 6146, 813, etc. The 3CX and 4CX ceramic tubes need high pressure for fast air movement to keep them alive. Note; cooling on these tubes is applied with filament voltage and run several minutes after removing voltage for cool-down. My 2m-8877 is run this way. I use a Lunar Link blower and seven-inch exhaust fan (originally for cooling 19-inch cabinets). Fan causes partial vacuum for blower to work into. Solid state amps occupy smaller "real estate" for similar power levels so big issue is heat conduction from the transistor to a air interface (cooling fins). I see most of the new LDMOS kilowatt level devices are mounted on thick copper bases to provide the lowest heat resistance and then mounted to aluminum heat sink fins. I would never think of running with out some air movement assistance (fans). Personally all my VHF+ high power LDMOS amps are being installed outside; 1. Primarily to lower coax run losses 2. Remove audio noise from the shack 3. Benefit from cool ambient air (here in Alaska summer air temp runs 15 to18c; winter its -5 to -10c on average). This might not be helpful if you live in hot climates and using climate-controlled interior air is better. My 1000w 6m amp uses five fans in a semi venturi manifold so air is also drawn thru cooling holes to interior ckt board. My 1296 600w LDMOS has 2-1/2 inch tall heats ink fins which I capped with a short manifold and two fans covering entire heat sink top to exhaust hot air. Only my 30w driver amp which is run 7.5w output is not fan-cooled. Have many days running outside this way. Outdoor enclosure has both 600w PA and 7.5w driver inside with air flow assisted by the two 120mm fans. 73, Ed - KL7UW ----------------------------------------- From: Howard Hoyt To: elecraft at mailman.qth.net Subject: Re: [Elecraft] L Bladeless Fan Technology Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed The Dyson ad is misleading: it merely has no EXPOSED blades. What it is is a venturi pressurized by a bladed fan in the base. In this way it is trading high-pressure low-velocity for low-pressure high-velocity which is appropriate for a fan in free-air to cool human bodies.? Fans designed to push air through heatsink fins are designed for moderate to high back-pressure depending on fin density and height. When we modeled our convective heatsinks for the KX2 & KX3, we also did designs with fans (and brought some to Dayton).? After iterating a heatsink design in ThermalCAD for hours to get the last percent more convective cooling, it is sobering and amazing how much heat you can remove by forcing air to remove the stagnant boundary layer of air from the heatsink.? It makes you realize natural convection is a very weak motor for air movement. A tube amp can potentially be quieter than a solid state unit due to the fact that the total heat removal in BTUs is directly proportional to the temperature differential between the air and the object being cooled (Newton's Law of Cooling). Analyzing the thermal path in each situation; the anode fins of a common 3CX or 4CX series tube are directly cooled by the air and can run at 250?C, whereas the transistor has some additional series thermal resistances to overcome before meeting the cooling air which can reduce the effective heatsink temperature at FET max junction temperature and heat flux to 125?C.? Assuming 25?C air, there can be a 225?C differential between air and tube anode, and a 100?C differential between the FET heatsink and air.? This means for any given volume of air passing through the two devices, there can be 2.25 times as many BTUs removed from a tube.? The other issue is the fact that the ceramic tube fins are designed for high pressure low-volume cooling, and most non-ducted FET heatsinks are designed for lower pressure, higher volume air flow. High-velocity fans typically create more noise than do higher pressure fans due to the relatively slower air movement and lower turbulence past the fins.? This being said I have used some really noisy tube amps. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From toms at xmission.com Mon Jun 4 16:41:58 2018 From: toms at xmission.com (Tom Schaefer) Date: Mon, 4 Jun 2018 16:41:58 -0400 Subject: [Elecraft] KPA1500 Signals attenuated in OPER Message-ID: <90FA1AA7-A193-48F0-9DAE-AF30769930BD@xmission.com> For some reason, when I switch to operate, signals are significantly attenuated.

That is in many cases, attenuation and RF gain reduction does improve the ability to copy a weak signal, be it SSB or CW.?? In most cases, optimal receiver performance is attained when the no signal noise is about 10 dB above the receiver noise floor.? Since one can't change the receiver noise floor, then attenuation and reduction of gain stages to bring the band noise down will then allow signals to pop out of the noise. On 160M, 80M & 40M to a large extent, I implement 15 dB of attenuation and reduce the RF gain accordingly.? At the same time, higher frequency bands have less noise and thus I can run less attenuation and/or more RF gain.? Finally on 12M, 10M and 6M I will engage the preamp.? I frequently encounter hams with the preamp engaged on 80 meters saying "it is needed to heard the weak signals".?? And I often find instances where the preamp is engaged along with the attenuation at the same time.?? That is much like driving your car with one foot on the brake and the other foot on the accelerator.?? I actually see a number of vehicles being driven that way.? At least that keeps the auto techs in business. 73 Bob, K4TAX On 6/4/2018 10:49 PM, Bill wrote: > > ??????

I took an Idiom Press SCAF-1 Tunable Audio Filter and put it between the audio out and my speaker. It removed most of the annoying hiss and while it may have introduced an issue or two others might want to avoid, those were unnoticeable to me. I was then able to listen to my MARS sessions without the fatique (or perceived fatique) that I used to have. After I sold the 7410, I put the filter on my K2 and it was a nice improvement to its audio. It has the KDSP-2 digital audio fliter in it which will tire you out as compared to the very pleasant audio of a K1. With the SCAF-1 between the K2 & my headset, it's almost like I have the K2's KAF filter without losing the advantages of the DSP one. Works for me. I'm not an engineer and what I do may not be recommended but it has made operating just a little more enjoyable.

The Super-Contest station of KL7RA (sk) is lined with acoustic tile and you note immediately how quiet the room sounds (even with radios turned off). Not sure how many of you knew Rich Strand but he was a radio astronomy consultant to NASA, flying world-wide to "fix" things at remote dish sites (thus his call sign).

The software is clunky but usable. There is a way to set other frequencies than what the pulldown menus offer. You need to go to and download a copy of the DSPLLsim utility in order to calculate the correct coefficients.. Below is a set of steps that Jan Verduyn has published that allows setting the two ports to other frequencies, in this case he was trying to get 10Mhz and 36MHz but using DSPLLsim you can work out other pairs. DSPLLsim is at If you only need one frequency then Bodnar also sells a smaller unit that is lower priced. AirSpy also sells this unit. Dave K5MWR From Jan Verduyn instructions for tailoring frequencies. Setting of the GPSDO Output 1 to 10MHz and GPSDO Output 2 to 36.000 MHz as external clock for the VNWA is done as follows: Start the GPS clock application for the Leo Bodnar standard 2 port GPSDO. 1. Set output 1 and output 2 to 10000000 Hz = (10 MHz) 2. Make sure both outputs are enabled 3. Press ?Find? and both output should be locked and produce 10.000 MHz 4. Now change the register details as shown below by typing in the following data: 10000000 = GPS Reference Hz 5 = N31 6 = N2_HS 450 = N2_LS 5 = N1_HS 108 = NC1_LS 30 = NC2_LS 0 = Phaseshift degrees (unchanged) 15 = BW unchanged 5. next press ?Update? button and both outputs should show red ? locked 6. If you measure with Frequency meter you will find that output 1 produces 10 MHz and Output 2 will produce 36 MHz. Note that the output 2 indication will continue to show 10 MHz, which is wrong. It should read 36MHz. These settings are stored when you switch off the GPSDO, When you apply power to GPSDO at a later date the same frequencies should be produced. Remember however as soon as you press the ?Find button? the settings will be lost and will need to be re-entered. If GPS Signals are lost then the output frequencies are derived from the built-in TCXO with the last correction factor applied before lock was lost. The above register settings were obtained using DSPLLsim utility. Make sure you select the SI5328 to obtain the correct settings. Attached is a screenshot of the GPS Clock Configuration screen. Good luck.

I always decide if I want the update, and if and when it can be applied. Your own the hardware, you license the software/firmware from the owner. The owner can make any changes they want without your input. But you can turn off updates. When you first load a program you have to agree to terms and conditions before you can proceed. You should read those, quite enlightening. Ted sez: This may be an instance of a much larger problem, one that has been discussed with regard to automobiles and light machinery among other environments of computer-type programming. It is, I suggest, a problem as much jurisprudential as electronic. When I buy a computer and an operating system, who owns it? Does it belong to he who bought and paid for it, or does it continue to belong to the company that produced it? Windows is not alone in this. Mac OS has its own version of forcing unrequested and often unauthorized updates, as is Samsung / Android or whoever makes those systems. Updates are installed at the producer's election, and as often as not in my experience with all three systems they disable or scramble the functions of some application I had been relying on. I don't recall granting permission to any of the operating system producers to enter my computer unacknowledged and change it, however benevolent their purpose may be. It is not a stretch in my mind to say that this is not much different from an automobile maker keeping the keys to the car I bought, finding it in my garage and entering it some night, and changing the color of the upholstery without my knowledge or consent. Absurd, right? From a macro-legal point of view, it's not a bad analogy. And then the complaints are met with silence. If a fix is offered, the user has to go hunting for it. No-one has ever told me that they patched something they fouled up. Elecraft itself it very different. Updates are announced; they are optional; the changes they make are described; and when a bug appears, the discussion even by the company owners is prompt and responsive. My ire is directed rather at the Big Three of the nether world. Users of the world unite!!

It will ALSO run fine (and preferred) at 5 volts DC from EITHER the USB port OR the External power connector. Here is what I do: 1) I don't have the GPSDO connected to the computer via USB when I am not ACTUALLY setting it via software. 2) I can run it from a USB cable connected to a "charge only" port on my computer connected hub OR from ANY port on the USB hub I use for "power only" and no connection to a computer. BOTH of these hubs have 12 VDC external power supplied STOCK by a 12 vdc switching PS (wall wart). "I" power them from the station power supply (13.9 VDC) via an LM317 based adjustable DC regulator that I set at precisely 12 VDC. 3) Alternatively, I can power the GPSDO via the Ext Power connector with 5 VDC from EITHER a USB cable hacked on one end to add the 5.5mm x 2.1mm connector (to the aforementioned USB hubs), OR via a twisted pair cable with 5.5mm x 2.1mm connector on one and and the other end terminated to connect to the 5VDC output of the regulator I mentioned earlier that primarily powers the HP 58516a GPS Antenna Splitter/amp. Bottom line... I eliminated the switching supplies from the picture and feed the GPSDO 5vdc to minimize the waste heat dumped into the GPSDO chassis. As an aside, and verified with Leo Bodnar, you can switch the GPSDO from computer connected to power ONLY WITHOUT cold booting the device (you do not have to power it down).? With the unit connected to the computer via USB, simply connect some other 5vdc power source to the Ext Power connector (USB or other as described above)? You now have 5 vdc going to both USB and Ext Pwr connectors.? THEN, disconnect the USB connection to the computer.? The unit is now on EXTERNAL DC only, no data/computer connection. I then perform an additional step...? I plug a pwer only connection BACK into the USB connector (to a charging-only or a power-only USB hub/power bus), and then remove the power cable from the Ext Pwr connector. Why? To remove the possibility that the computer connection might feed something back into the GPSDO and affect its frequency outputs. 73, ______________________ Clay Autery, KY5G (318) 518-1389 On 06/05/18 09:31, Grant Youngman wrote: > I?ve been using one in the station for a long time (starting years ago before the K3 came along).

First, in my post I described the matter not as a legal qissue -- that is to say, not what it is technically legal to do -- but as a jurisprudential question -- that is, given the broader and deeper traditions of American law, what should the operative legal principles be. Second, even on the question of waivers and consents and the like, take a look sometime at what became known as the shrinkwrap problem. Briefly, even before operating system manufacturers created even less accessible license and waiver texts, manufacturers of consumer electronics and other goods included their warranty limitation language inside the box, wrapped in plastic, which the buyer could not in any practical way read before making the purchase. Manufacturers nonetheless attempted to enforce their warranty limitation terms when defect problems arose. Some court decisions -- the better ones, in my view -- said no way; that's flat-out contrary to more fundamental principles of American contract law. As a practical matter, Windows 10 is sold to millions of people in an effectively equivalent way. As one example I bought a MS Surface laptop at an MS kiosk in a mall. When I bought it it had been fully loaded by MS's representatives and handed to me, ready for me to key in my passwords. I never saw nor had a chance to see anything disclaiming or waiving or defining anything before they charged my account. I therefore in fact agreed to nothing. Period. To say that I impliedly agreed because I should have known there was some pro-vendor verbiage somewhere inside is not a valid legal argument: it's the sort of argument that could legalize anything that was common usage no matter how nefarious. So I stand by my point that from a jurisprudential point of view, who should have what rights to change something in my computer without legally adequate notice to me and an opportunity to decline is a serious question worthy of some deeper analysis. ------------------------------ Message: 21 Date: Tue, 05 Jun 2018 14:10:38 -0400 From: w3ab To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Elecraft K3 USB Drivers Message-ID: <666ec53cfc774a86196c3db951b99eb9 at w3ab.org> Content-Type: text/plain; charset=US-ASCII; format=flowed . . .

I have yet to figure out how to use it correctly.? But there are those who have and MAY be amenable to calculating them for you. ____________________________________________________ Here are TWO methods for setting 36MHZ and 10MHZ together: Method #1: Output #1 = 10MHz; Output #2 = 36MHz? (Thank you, Jan!) Start GPS Clock Configuration application 1. Set Outputs 1 & 2 (Hz) to 10000000 (10 MHz) AND "Output Drive Strength" to 8mA. 2. Make sure both output enable boxes are checked. 3. Press ?Find?.? When complete, both outputs lock at 10000000 Hz.(10MHz) 4. Now, enter the following register values: ____________________________ 10000000? = GPS Reference Hz 5???????? = N31 6???????? = N2_HS 450?????? = N2_LS 5???????? = N1_HS 108?????? = NC1_LS 30??????? = NC2_LS 0???????? = Phase shift degrees (unchanged) 15??????? = BW? (unchanged) ____________________________ 5. Click "Update".? When finished, both will show 10000000 MHz, BUT wait! 7. Close the GPS Clock Configuration app.? Then restart the app.? The displays will update to reflect 10 MHz on Out #1 and 36MHz on Out #2.? You can confirm this by measuring them with a frequency counter/meter. DO NOT PRESS "Find"!? If you do, you will set both to 10MHz and have to start all over. ++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++ Method #2: Output #1 = 36MHz; Output #2 = 10MHz? (Thanks to Simon @ Bodnar) Start GPS Clock Configuration application 1. Set Output 1 (Hz) to 36000000 (36 MHz) and "Output Drive Strength" to 8mA. 2. Make sure both output enable boxes are checked. 3. Press ?Find?.? When complete, both outputs lock at 36000000 Hz.(36MHz) 4. Now, enter the following register values: ____________________________ 4800000? = GPS Reference Hz 11??????? = N31 11??????? = N2_HS 1350????? = N2_LS 9???????? = N1_HS 20??????? = NC1_LS 72??????? = NC2_LS 0???????? = Phase shift degrees (unchanged) 15??????? = BW? (unchanged) ____________________________ 5. Click "Update".? When finished, both MAY show 36000000 MHz, mine displays correctly about a third of the time.? BUT as before... wait! 7. Close the GPS Clock Configuration app.? Then restart the app.? The displays will update to reflect 36 MHz on Out #1 and 10 MHz on Out #2.? You can confirm this by measuring them with a frequency counter/meter. DO NOT PRESS "Find"!? If you do, you will set both to 10MHz and have to start all over. Here is an image to illustrate the results: http://www.montac.com/images/vnwa/36x10Mhz_Bodnar.jpg ================================ NOTE: You can tell the "Find" or "Update" process is complete when ALL three labels ("Find", "Update", and "Sleep") are NOT "greyed out.?

That can happen if you are using the Signalink cable to the 8 pin mic jack -- However, if you are using the Signalink LINE IN/LINE OUT connections to the K3 rear panel, you also need to connect the Signalink PTT output to the K3 PTT input. Alternately, you can set VOX to ON in the K3 - it works fine.

The 10 MHz source should have a signal level between +4 dBm and +16 dBm, nominal. For square wave sources, 2VDC to 3.3VDC peak is optimum. If the source is a 5V logic level, use a 50-ohm resistor in series with the input. Caution: To avoid damage to the K3EXREF, do not exceed these levels." So, it would appear that the +8dBm setting I have set as per the VNWA directions for 36 MHz, will work in that respect for the K3s. As I understand it, the Bodnar unit is square-wave, so the only question is what is the voltage envelope for the signal? I STILL am awaiting my crimper to match my cable stock, so I can't make a BNC to SMA cable to test the Bodnar output. The DC voltage on the output from my non-RMS multimeter is about 1.589 VDC, so that would indicate 2 x 1.589 = 3.178 approx. pk-pk, right? This agrees with the Bodnar site which says: "Both output signals are at 3.3V CMOS levels with 50 Ohms characteristic impedance." Thus, my conclusion would be direct connection via jumper wire only; no attenuation, et al. required. Thanks!? It was easier to research than I thought.? ______________________ Clay Autery, KY5G (318) 518-1389 On 06/05/18 14:31, Grant Youngman wrote: > My Trimble Thunderbolt puts out +7 dBm. ?The Bodnar can be set for > +13-something down to +7.7 dBm. ?Sounds in the ballpark. > > The Trimble hasn?t torched anything. ?I don?t recall seeing specs on > maximum input power for the K3 but I haven't looked at it for a while, > have a short memory, and they?re probably there somewhere in the > paperwork ? > > > Grant NQ5T > K3 #2091, KX3 #8342 > >> Can the Bodnar be fed to the K3s directly bu jumper without >> attenuation??

I was kind of stumped by Clay's question. Disciplining I take to mean controlling from an external source - huh? why? If you want GPS frequency accuracy then buy a GPSDO for a couple hundred dollars, but as far as affecting K3 frequency accuracy it will not be significantly more accurate than using an OCXO (Oven Controlled Xtal Oscillator). The Morion spec for short term stability is +/- 5 E-12. Long term stability is+/- 5 E-5. The OCXO drifts about 1-Hz per 6-months from my actual measurements. So, yes it needs to be disciplined occasionally (twice a year) manually by adjusting the freq. adjust pot comparing its output to an accurate 10-MHz source (I use my LPRO Rubidium as my reference). The short term stability of the Rb is +/- 5 E-11 but that is "good enough". BTW the K3 frequency is established by the TCXO and the external reference merely performs a periodic check. Any freq error causes a correction instruction to the TCXO to bring it back onto frequency. The TCXO-3 is rated at 0.5 ppm which is +/-5 E-7. Adding the EXREF limits drift to 0.1ppm or E-7. At 28-MHz that implies a 28 E+6/E-7 or 2.8 Hz. The TCXO drift is limited to +/- 2.8 Hz. The OCXO is 10,000 times more stable and thus more accurate. The reason you do not get the OCXO level of stability is that the EXREF system does not phase-lock the TCXO. It periodically corrects the error but the TCXO drifts normally between freg corrections which happen often enough to reduce the amount of drift from 5.6 Hz to 2.8 Hz at 28-MHz. The OCXO returns the TCXO to between 28,000,000.0005 Hz to 27,999,999,9995 Hz but then the TCXO drifts 2.8 Hz by the next frequency check. I think 0.0005 Hz is close enough. So maybe the GPSDO is +/- 5 E-13. That would correct the K3 to 0.000005 Hz, but it would still drift 2.8Hz by the next frequency check. My actual frequency measurements show 0.5 to 1.5 Hz inaccuracy at 28-MHz and 1.5 to 2.5 Hz inaccuracy at 50-MHz so my TCXO-3 is doing better than 0.5ppm. Now if you want to know why Elecraft chose periodic freq correction over true phase-locking, the answer is low LO phase noise. Much harder to get low phase noise in a PLL than in a TCXO. And now you know the rest of the story. 73, Ed - KL7UW From: Wes Stewart To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S XREF GPSDO recommendation needed I'm not answering for Ed, and I don't have the Ref Lock doodad for my K3. That said, a decent OCXO, like a Morion, will have, after warm up and a little aging, stability more than adequate to discipline a K3.? The K3 isn't phase locked to an external reference anyway, it's just "nudged" on frequency periodically. If GPS lock is lost on the Bodnar device it reverts to a TCXO that is likely no better than the one in the K3, assuming the high stability option.?

I have the Bodnar unit because my sweetie asked me what I wanted for Christmas a few years ago and I had just read about it.? I have no compelling need, but I did use it with a modified SDR-IQ to try my hand at the last ARRL FMT.? I also have a Morion, off eBay, that I thought I should have.? I have yet to apply power to it :-)? I suppose I was remembering the days when I would have killed to have something that accurate. Likewise after reading timenuts I thought I should get a TAPR GPS time standard kit.? I have absolutely no need for that either but Lady Heather looks nice on a spare computer screen ticking away at one second increments with nanosecond accuracy :-). Wes?

The K3 uses a counter lock scheme that does NOT change the phase noise of the internal oscillator. This is real obvious if you measure the 'locked' oscillator. When locked it still drifts around +/- 0.5 Hz. This is just marginally good enough for the ARRL Frequency Measuring Tests.

Why discipline the OXCO, or even the DOXCO? Because you can. Because the ability is there to progressively steer the correction instead of stomp on it twice a year. Lots of reasons, not the least of which is not having to open a chassis and/or drill a strategically placed hole in a chassis in order to allow you to manually make the correctly. And there are those of us who use the frequency reference for things other than just our radios. BUT I understand why you do it the way you do, now.? Which was the intent of the original question.? Thanks! And I do appreciate the information that the K3 is not phase locked and why the choice was made. Does anyone have any idea how often that "check and nudge" procedure is done or better the logic behind how it is determined when to make a correction?? I assume it is implemented in firmware.

During this count time, the circuitry draws about twice as much current as when it's static (it goes from 7 mA to 15 mA). When it's drawing more current, it slightly decreases the supply voltage to the reference oscillator, causing a small frequency shift observable at 2 meters and possibly even on 6 meters. The mod is simple to apply.

The associated T/R control firmware hasn?t changed in a long time, so hopefully there aren?t many users affected (or we would have heard about it). The shorter delay may be related to the improved KSYN3A synth, which switches faster than the original. We?re looking into this, and will update the displayed value to reflect the actual value. Details: When using a QRO amp with the K3, the KEY OUT line from the radio is used to key the amplifier, setting it up to receive RF. Since the K3 has very fast QSK, the amp?s T/R control circuitry has to be similarly fast. Those of you who are using KPA500s and KPA1500s need not be concerned about the K3?s fast QSK speed, since our amps use PIN diode T/R switching. They can easily keep up with the K3 at any code speed and with the default setting of the CONFIG:TX DLY menu entry. However, some other amps, especially older ones, use slow T/R relays. If the transceiver generates RF before the amp is ready, this might result in key clicks. (In practice there?s a bit of a grace period because the RF keying envelope rises very slowly. It?s a "raised-cosine sigmoid," resulting in the transceiver itself having incredibly clean keying sidebands. See K9YC white paper on this topic.) If you suspect your amp has a slow T/R relay, you should do a listening test, or better yet have someone else listen from a good distance. If you (or they) hear any evidence of clicks, increase the value of CONFIG:TX DLY. Use the lowest setting that eliminates the clicks. CW keying at higher code speeds may be affected if the value is too high. Other modes not using fast QSK will generally be unaffected (voice and data). An alternative to increasing TX DLY is to use a foot switch, as do many users of old amps regardless of transceiver type. 73, Wayne N6KR From bobk8rl at aol.com Thu Jun 7 20:22:34 2018 From: bobk8rl at aol.com (bobk8rl at aol.com) Date: Thu, 7 Jun 2018 20:22:34 -0400 Subject: [Elecraft] [FS] SP3 Message-ID: <163dcc601f2-c91-9eaf@webjas-vab028.srv.aolmail.net> For sale Elecraft SP3 speaker.

Message-ID: "I'm pretty sure I am seeing people running data WELL beyond the band plan into the SSB section of several bands... 20m for almost certain." Quite possibly the RF second harmonic of an in-band 40 m signal. It's unlikely that anyone would hope to work a data mode QSO far away from the accepted normal frequencies. 40 m data is allowed up to 7.125 and twice that is well into 20 m phone allocation. Even the typical FT8 upper limit of about 7.076 has a second harmonic inside 20 m phone allocation. 73, Andy, k3wyc From jim at audiosystemsgroup.com Fri Jun 8 01:03:42 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 7 Jun 2018 22:03:42 -0700 Subject: [Elecraft] Nice 6 m opening right now In-Reply-To: References: <20180607224853.F07E1149AF41@mailman.qth.net> Message-ID: <4e58c707-21be-4500-3d5e-25cfb40a118c@audiosystemsgroup.com> On 6/7/2018 6:16 PM, Clay Autery wrote: > Can someone send me a screen cap off a P3 or something of the waveform > for FT8 (and any other digital mode). Hi Clay, It's worth downloading WSJT-X, installing it, RTFM, and then start listening. It's excellent software, well written, well documented. And, if you RTFM, easy to use. Among other things, that will get your ears tuned in to what those modes sound like -- just set your Mon gain so you hear what you're TXing, and you'll know. Hookup to K3/K3S is super easy. feed the Line In from Computer Out, Feed Computer in from Line Out, set the K3/K3S for Digital A and VOX. in WSJT-X, push Tune to get the computer to send a steady tone, set Line In Gain and VOX Gain so that you go into TX, adjust Line In Gain so that ALC flickers 4-5 bars. Adjust output from rig to Computer so that you get indicated 30-40 dB on the WSJT-X bar graph. Choose FT8, select the band you want to try first, and you should see decodes every 15 seconds.? Also, WSJT modes require a clock within about 1 sec, do whatever is needed to accomplish that. I use this one. http://www.timesynctool.com/ 73, Jim K9YC From KY5G at montac.com Fri Jun 8 01:16:26 2018 From: KY5G at montac.com (Clay Autery) Date: Fri, 8 Jun 2018 00:16:26 -0500 Subject: [Elecraft] Nice 6 m opening right now In-Reply-To: <4e58c707-21be-4500-3d5e-25cfb40a118c@audiosystemsgroup.com> References: <20180607224853.F07E1149AF41@mailman.qth.net> <4e58c707-21be-4500-3d5e-25cfb40a118c@audiosystemsgroup.com> Message-ID: <3ce8ea7c-c33a-2f48-7f07-12ba006168d5@montac.com> Thanks Jim....

Hi Dimitry, I strongly agree. I HATE foot switches, because I'm very poorly coordinated. :) I've never used anything but VOX in my own station for any mode, and I do RTTY, CW, and SSB contesting, run FT8, JT65, JT9, MSK144 for small signal work. With every rig I've owned since 2003 (when I had time to back on the air) I've been able to set the delay between transmitted RF and the DC signal to pull in the TR relay for a power amp to the value that my amps have needed. The high quality, well designed amps I've used have never needed more than 8 msec. That's me. Everyone is different. :) 73, Jim K9YC From ua9cdc at gmail.com Fri Jun 8 06:22:42 2018 From: ua9cdc at gmail.com (Igor Sokolov) Date: Fri, 8 Jun 2018 15:22:42 +0500 Subject: [Elecraft] Default K3 transmit delay may be too short for slow QRO amplifiers In-Reply-To: <7310F839-A99A-4AF8-B5EA-753DEF4DD4D4@elecraft.com> References: <7310F839-A99A-4AF8-B5EA-753DEF4DD4D4@elecraft.com> Message-ID: Wayne it is a pity that TX delay setting affects CW timing.

I HATE foot switches, because I'm very poorly coordinated. :) I've never used anything but VOX in my own station for any mode, and I do RTTY, CW, and SSB contesting, run FT8, JT65, JT9, MSK144 for small signal work. With every rig I've owned since 2003 (when I had time to back on the air) I've been able to set the delay between transmitted RF and the DC signal to pull in the TR relay for a power amp to the value that my amps have needed. The high quality, well designed amps I've used have never needed more than 8 msec. That's me.

Instead of weighting, as Wayne suggested, set "Keying Compensation" or "1st dit extension" to match the actual TX DLY. This will restore proper CW timing ratios in the transmitted RF, as you increase TX DLY, since every dot or dash (or the first one in a message) will be lengthened by a fixed number of ms. No footswitch is required, since external keying methods can generate a leading PTT delay. If you are using the internal keyer of the K3 for hand sending, compensation is automatic. No need for any adjustment; use any TX DLY value you need, and the transmitted dot/dash ratios will still be perfect (I've measured it on a scope). If using external keying with a WinKey, use the menu setting for "Keying Compensation" (QSK), or "1st dit extension" (Semi-Breakin). to apply matching keying compensation. Example: CONFIG: TX DLY 010 Actual measured TX Delay 7-8 ms (with jitter) Set External Keying Compensation (for QSK) to: 7 ms Set 1st Dit Extension (semi-breakin) to: 7 ms If using a microHAM Device with a built-in WinKey, the menu settings for these values were (unfortunately) moved from the WinKey tab of the Router software. Instead, they are now a single setting under the PTT tab, called "R/T Delay" (improperly documented). So, in the microHAM Router, PTT tab: Set R/T Delay to 7 ms If using a LogiKey K1 or similar: Set the "K Factor" (keying compensatin) to 7 If using Win-Test with CONFIG:PTT-KEY OFF-DTR for QSK keying over the serial port DTR pin, or an external keying circuit, set the Keying Compensation in the Interface Configuration menu to 7 ms (this a new feature in Win-Test 4.28.0-dev). If using semi-breakin, set CONFIG:PTT-KEY to RTS-DTR and tell Win-Test to use a PTT Lead time of 10-20 ms, 0 ms keying compensation. Most WinKey/N1MM users can simply rely on setting the WinKey PTT Lead time to a sufficient value. Unfortunately, the WinKey PTT lead times are set in increments of 10 ms (0, 10, 20, 30 ms), despite the menu settings. If you ask for 11 ms of PTT delay in a WinKey, you actually get 20 ms of PTT delay. Note that the K3 will safely ignore any PTT lead time less than TX DLY, so if you set PTT LEAD to 3 ms you will actually get 7 ms and all elements (QSK) or the first element (semi break-in) will be shortened by 7 ms. FYI, the OM Power OM2000A+ non-QSK amplifier manual recommends a TX DLY of 20 ms (!). Final note: if using CW QRQ mode, the K3 ignores TX DLY completely, and you get 4-5 ms of TX DELAY (fixed, with jitter). Set keying compensation to 4 ms. 73, Bob, N6TV From ve7xf at shaw.ca Fri Jun 8 14:27:07 2018 From: ve7xf at shaw.ca (Ralph Parker) Date: Fri, 8 Jun 2018 11:27:07 -0700 Subject: [Elecraft] Foot switches Message-ID: >>Why in the 20 century we need to use foot switch? >I strongly agree.

I assume you are using CONFIG:PTT-KEY set to RTS-DTR to have T4RW provide CW and PTT over the K3 USB cable (or serial cable). > I use external keying from computer through USB-COM adapter. OK. For the K3S, or K3 with KIO3B upgrade, no adapter is required (it is built in to the K3). > The logger that does CW keying is TR4W. No keying compensation helps to > achieve correct CW weight if TX Delay in K3 is set to say 20ms and CW speed > used is above 30WPM. The TR4W manual says: "7.Support for PTT with programmable delay to ensure that antenna relays are cold-switched." But I could not find any further documentation showing how to set the CW PTT delay to 20 ms in TR4W. If the PTT line is held closed by the software, no keying compensation is required, and CW output will be fine. But, if you're trying to do QSK (full break-in) with VOX and external keying from TR4W, with no PTT output, you will either have to use a different radio, or use different software like Win-Test that (in v4.28.0-dev) supports keying compensation, or an external keyer with PTT or keying compensation, like a WinKey. Perhaps you can convince the author of TR4W to add keying compensation ( *not* weight), a setting that lengthens every dot or dash by a fixed amount. > Dependency of CW weight from TX Delay is only inherent in K3. All other > rigs do not have this dependency. > Most rigs will shorten the first dot or dash (semi break-in) or every dot or dash (QSK full break-in) by a few ms to compensate for the TX delay setting, the delay between the amp RELAY closure, and the RF output. Some rigs may use a hardware "buffer" for external keying, to provide perfect timing even with a PTT delay, but I don't know which ones do this (Icom perhaps). Again, for hand sending with the internal keyer of the K3, all TX DLY values work fine, no shortening of RF output. 73, Bob, N6TV From wunder at wunderwood.org Fri Jun 8 18:24:46 2018 From: wunder at wunderwood.org (Walter Underwood) Date: Fri, 8 Jun 2018 15:24:46 -0700 Subject: [Elecraft] Default K3 transmit delay may be too short for slow QRO amplifiers In-Reply-To: References: <7310F839-A99A-4AF8-B5EA-753DEF4DD4D4@elecraft.com> <959632774.2001731.1528477642117@mail.yahoo.com> Message-ID: <948CB54C-FE8C-4FA2-A626-B2E65C5A6BE6@wunderwood.org> Maybe you could put a tone generator on the foot switch to bleep yourself.

Not sure how to pull off reducing the input from 12 to 5vdc with a single external resistor. I DO know how to do it with a voltage divider....? Vout = Vin x R2/(R1+R2)?

It uses the so-called "AG6K circuit" which supposedly makes the usual Jennings RJ1A relay operate in 2-3 ms. I never had any problems with the default delay of the K3, both before and after installing the new synthesizers. I do recall that with the old synthesizers and an external keyer, increasing the delay above the default even a little seriously messed up the CW timing. However now I have the new synths. So on reading Wayne's announcement I decided to so some testing. I don't notice ANY difference in CW timing, either with the internal keyer or with an N1MM-operated Winkey, with QRQ mode on or off, with TX Delay set from 8 to 20 ms., in semi or full QSK mode, up to 40 wpm. I listened to both the sidetone and the transmitted signal. I didn't measure anything with the scope, but I have always been sensitive to CW timing, and it sounded the same to me. So the upshot is that if you have a slow amplifier, you should be able to just increase the TX DELAY as needed. And if Bob is right, turn off QRQ mode too. But it would be prudent to check the timing with your particular amplifier with a scope before taking my advice! 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 8 Jun 2018 21:12, Bob Wilson, N6TV wrote: > If you are using the internal keyer of the K3 for hand sending, > compensation is automatic.

Yes, a 12 volt source may damage the K3. A simple voltage divider will not do the whole job. That output must swing from 5 volts to zero volts., so at the the time the output should go to zero volts, the voltage divider will still be producing voltage. Look at the schematic for the driving device. What is the device providing the output? A relay, or a solid state device? If a relay, is it a SPDT relay with the output taken from the common? Is the NO contact connected to ground? Is the NC contact connected to +12v - if so, remove the source of 12 volts and connect a 2.2 to 10k resistor to that contact with its other end connected to a source of 5 volts. If instead of a relay, the output is a solid state device (transistor or FET) disconnect the collector (or drain) resistor and replace it with a 2.2k to 10k resistor with the other end connected to source of 5 volts instead of 12 volts. In other words, you will have to modify the driving device - alternately, you could add a device to the circuit (internally or externally) which takes the 12 volts as an input and uses a 2.2k to 10k collector (or drain) resistor terminated in 5 volts - a 2N7000 FET would work fine. That output would go from 0 volts when the input is 12 volts and go to +5v when its input is 0 volts. 73, Don W3FPR On 6/8/2018 11:12 PM, Clay Autery wrote: > I'm going to use ACC Pin #7 as Transmit Inhibit (High), and the manual > says this: > > "TX INH (Transmit Inhibit Signal) > Pin 7 of the ACC connector can be configured as a > transmit inhibit input by setting CONFIG:TX INH > to LO=Inh (or HI=Inh).

Perhaps it has KEY IN / KEY OUT, and you can use that instead, to activate PTT on the radio only when the amp. is "ready". PTT signal or footswitch keys amp., amp. keys K3 PTT IN, instead of PTT/footswitch keying radio, and radio keying amp. Or you could set CONFIG:TX DLY to a large value. If you must use the TX inhibit pin, 5V is available on K3 ACC Pin 1 (FSK keying). I use that plus a single resistor on my Simple K3 Lockout Circuit (see https://bit.ly/K3lockout which downloads a PDF schematic). The Y-BOX has this lockout circuit built in, as well as a 10K pull-up resistor for a separate 5V source if the FSK pin is already in use for RTTY. But, the circuit uses TX INH LO and you need TX INH HIGH? You could use the 12V from the amp. to key the base of an NPN transistor (through a 1K resistor). Ground the emitter and and connect a 470 ohm resistor to the collector. Connect other side of the resittor to the TX INH pin and +5V (Pin 1), as in my lockout schematic. When your amp outputs 12V, the transistor closes the circuit, and the INH pin goes low. When your amp. outputs 0V, that opens the circuit, and the INH line goes high (+5V). 73, Bob, N6TV On Fri, Jun 8, 2018 at 8:12 PM, Clay Autery wrote: > I'm going to use ACC Pin #7 as Transmit Inhibit (High), and the manual > says this: > > "TX INH (Transmit Inhibit Signal) > Pin 7 of the ACC connector can be configured as a > transmit inhibit input by setting CONFIG:TX INH > to LO=Inh (or HI=Inh).

That and very low phase noise and exceptional receiver dynamic range are why the K3 is such a superb Field Day transceiver. At the W3AO Field Day we use four K3 transceivers on 20 meters: CW, SSB, Digital and GOTA. N one of the 20 meter operators will be aware of the other three transceivers u nless one of the other transceivers accidentally lands on the same frequency. Is there any published data about the performance of the built in bandpass filters? tks 73 Frank W3LPL ----- Original Message ----- From: "Wayne Burdick" To: "Bill" Cc: "Elecraft Reflector" Sent: Saturday, June 9, 2018 4:34:53 PM Subject: Re: [Elecraft] Field Day rig experience > On Jun 9, 2018, at 5:24 AM, Bill wrote: > > Along the line (lightly discussed under "K3- AF Knob") of what rigs are used for dxpeditions and Field Day......

Proximity of antennas was close, on the order of 40 (tribander)-200' (double double extended Zepp on 40M) separation, power output limited to 100 watts.? There was a lack of trees to make more space between antennas without exceeding the 1500' limitation (besides, the snacks were there). The 7300 crumpled badly, operation on other bands 'desensed' (for lack of an accurate word) the 7300 effectively making it deaf in some cases.? It didn't matter what band the other stations were operating on, the 7300 was affected. No band filters were employed, it was a brutal test as a 'worst case scenario'.? The 7300 failed. The Pro-III the group normally uses, displayed no issues.? No one wanted to dis/re-assemble their Elecraft stations from home but I'm sure they'd hold up very well or better under the same test.? It wasn't a QRP event, so the KX2/3 was not deployed. However it's limitations, the 7300 does exactly what I intend it to be, a cheap light weight radio with 100 watts out that I can take into the field, use in the RV or the home shack (since I can control other transmitters).? It isn't an 'unworthy' radio, if you don't subject it to high RF fields. Eventually, I'll have a second K3 just for the RV but for now the 7300 will suffice. There will be two 7610 on site this year, but I won't be there to witness their use.? The Pro-III will be there in case the 7610 doesn't hold up.

Transceiver can not supply multi sequenced events, but can prevent to burn LNA if have long TX DLY time and input of sequencer connected to PTT of K3. You can say, who connect sequencer to the transceiver, sequencer must engage TRX and not contrariwise. Two ways is right, but every way have weakness. In first way when sequencer gives PTT command to TRX - pushing on "Send", "XMIT" or PTT on microphone or keyer will destroy LNA etc. if do not use TX Inhibit. In second way when we have enough delay between PTT signal and RF output - we need to set delay time little bit more then all commutations needs, for example I know my mast LNA needs 30ms, PA 40ms plus additional 10ms, so for safety use 80mS is enough(if U use delay time between LNA off and PA ON). I have use sequencer in the PA( sequence ~60mS) and generate -9V for TS-2000, for K3S I need different voltage for TX Inhibit, all this signals needs only because I do not have option to set TX DLY more than 20mS!

But looking at it theoretically: both the 7300 and 7610 are direct-sampling radios with about 25-30 dB less blocking dynamic range than the K3 or K3S. On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used. > > Dynamic range of all of these radios is quantified in the receiver performance table at www.sherweng.com, specifically the fifth column (?100 kHz Blocking?). > > Wayne > > > > ______________________________________________________________ > 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 xdavid at cis-broadband.com From k9ma at sdellington.us Sat Jun 9 15:54:37 2018 From: k9ma at sdellington.us (K9MA) Date: Sat, 9 Jun 2018 14:54:37 -0500 Subject: [Elecraft] Field Day rig experience In-Reply-To: <60985b55-7704-0900-9867-116b3e620b2e@cis-broadband.com> References: <23aceae9-88ab-7272-6345-3dfcf9a70112@nycap.rr.com> <4CC3643A-1115-4150-B5B1-CAE014617C99@elecraft.com> <60985b55-7704-0900-9867-116b3e620b2e@cis-broadband.com> Message-ID: <6f92dc7c-c0c0-46ff-3d42-463cdee0c703@sdellington.us> On 6/9/2018 14:52, David Gilbert wrote: > I think another major concern for closely positioned rigs would be > transmitted phase noise, and of course that doesn't show up in the > Sherwood? charts.

(Thanks to the 2 folks who replied!!) Task:? Build a cable that connects my K3s to an SPE 1K-FA amp (on loan until I can buy a KPA-1500) using the TX-INH signal from the SPE amp to INHIBIT the K3s from transmitting ALL the time UNLESS it is the selected exciter AND it sends the SPE amp a "key/relay" signal. Purpose:? To use the SPE as the arbiter of which INPUT/EXCITER has the drive privileges, to future proof the cable wiring for probable AMPLIFIER sharing between TWO exciters at some point. If BOTH exciters are put into inhibit BY DEFAULT by the SPE, an exciter may ONLY drive the amp IF, 1) the exciter is connected to the ACTIVE SPE exciter input, AND 2) the exciter sends a key/relay signal to the SPE amp.? There's a lot of other logic involved, but this is the key point....? BOTH exciters are Inhibited by default (TX light blinking on K3s), and ONLY one may EVER drive the amp at one time.? No external devices required. Components/Connections: K3s, using ACC port, Pin #7 (with TX-INH set to "High") (and of course Pin # 5, GND)? (There are other pins being used, but I am pairing it down to JUST this topic) SPE 1K-FA Amp Input #1 CAT port, Pin #13 (TX-INH) and Pin #4 GND. The SPE Amp outputs +12VDC on the TX-INH signal line to the exciter UNTIL the amp sends a key/relay signal to the amp, at which point the SPE amp drops the TX-INH signal to 0 vdc. Background:? The fellow I got the cable pinout, et al. from actually had the SPE TX-INH connected to the K3s Pin #7 (TX-Inh set "High) for over a year with no ill effects.? When he was informed that the SPE was using 12VDC, but the K3s was expecting 5VDC, he put a simple voltage divider on the signal line and to ground to reduce the SPE's TX-INH voltage to +5vdc, and it still works.? I am simply going through this inquiry to MAKE SURE that I am providing the K3s the specified voltages for the two states (TX Inhibited and TX Enabled). Questions: 1) What does the K3s expect to "see" at Pin #7 with TX-INH set to "High" (and low for that matter)? Is it, as I suspect, TX-INH set to "high" TX inhibited = +5 VDC and TX Enabled = 0 VDC.....?? OR.....? TX-INH set to "Low"; TX Inhibited = 0 VDC and TX Enabled = +5 VDC, or is it more complicated where the K3s wants to see +5VDC on BOTH sides of the TX-INH setting, where with TX-INH set Low, it's the same"? Inhibited = 0VDC and TX enabled is +5 VDC, BUT TX-INH set to "High" it wants to see TX Inhibited = (x volts above +5VDC) and TX Enabled = +5VDC.? I would think it is the former.... but the fact that it worked at 12 VDC for a year without torching/letting the smoke out of anything gives me pause. 2) IF the K3s simply expects +5VDC for Inhibit and 0 VDC for Enabled on Pin #7, and the SPE amp supplies the +12 VDC on the signal line for INHIBIT and then grounds that output for Enabled, why can't a simple 2 resistor voltage divider (or pot) can't be used to drop the SPE output from +12 to +5 VDC, or indeed why you couldn't simply use a single inline resistor of the correct value to do it? I should probably just replicate what has been proven to work and not worry about it, but I truly want to understand why/how this is supposed to work, so I know I am providing the signal levels intended. Going schematic diving.... 73 ______________________ Clay Autery, KY5G (318) 518-1389 On 08-Jun-18 22:12, Clay Autery wrote: > I'm going to use ACC Pin #7 as Transmit Inhibit (High), and the manual > says this: > > "TX INH (Transmit Inhibit Signal) > Pin 7 of the ACC connector can be configured as a > transmit inhibit input by setting CONFIG:TX INH > to LO=Inh (or HI=Inh).

We test every amp for IMD, and we see an average of about -35 dBc (3rd order, ARRL method) across all bands. This is state of the art for an LDMOS deign running class AB. Other SS amps using similar designs have have similar performance. Any amp?s gain levels off as it approaches peak power (ie, is slightly in compression). But it should not be flat-topping unless it?s over driven or is starved for supply current/voltage. Finally, both the transceiver and amp will vary from band to band somewhat in IMD. You might for example see -40 dBc on one, but in the low 30?s on the other, on a given band. Again, this is typical of all such SS rigs/amps except those running class A or using closed-loop feedback (predistortion). Please call Monday to discuss your test method with one of our technical staff. 73, Wayne N6KR ---- http://www.elecraft.com > On Jun 9, 2018, at 2:21 PM, K9MA wrote: > > I recently ran a two-tone test and measured CW power gain.

The W7, Israeli and Russian boards were used and they all suffered the same fate in various degrees. They would cease being very linear at about 75% of their CW output. Careful selection of bias and feedback levels would allow some improvement but in none of the cases were the devices even close to acceptable IMD wise at their data sheet output levels. The only one that am aware of that worked well was a W8 friend who is driving it (EB-104 water cooled Russian amplifier) with an Anan and used Pure Signal to effectively clean it up. On all of the others when the output came up to the target level you could immediately start seeing them in the opposite sideband. All of the data sheets that we saw at the time talked about CW/FM applications and none provided specs for SSB linear service. These have been my observations of the BLF-188 amps.

I AM making progress. What I have learned thusfar...? (Thanks for the patience of Don, WFPR and others.) ... and correct me if I am wrong, PLEASE. 1)? Pin #7 is TTL logic...? And logic pins need to NOT be left floating.? They need to see discrete logic high (+ 5vdc) or low (0 vdc) levels at all times. (Playing with the TX-INH settings on the K3s with nothing connected, I have seen what happens when the pin is left floating... the MCU doesn't know what it's going to get...? I've successfully gotten it to inhibit AND enable on both settings.) 2) The pull-up resistor basically acts sort of like a current limiter on the input pin and a load when the pin is pulled to ground. 3) Lower pull-up values improve switching speed.? Smaller is faster, but too small and you get too much current and power consumption/heating become issues.? Too high, switching too slow and voltage level may not be high enough to clearly be taken as a "high" logic state. 4) The "switch" needs to be between Pin #7 and +5VDC....? and Pin #7 So now, it's just a matter of? putting? together a switching circuit that feeds Pin #7 with +5VDC when the SPE TX-INH signal is 12 vdc, and when the +12 vdc is removed, Pin #7 sees 0 vdc.? Seems simple, but... Here is a link to a draft circuit I've drawn up based on a suggestion as to a particular MOSFET to use as a switching device: http://www.montac.com/images/circuits/TX-INH_circuit.jpg Notes/Questions: Q1 = 2N7000G Small Signal MOSFET (N-channel) R1 = Pull-up resistor, as per manual (2.2-10 kOhms) ?? R2 = Pull-down resistor, value unknown.? Needed?? I THINK it might be needed in view of the "requirement" for R3 below, and to potentially avoid using D1 below. R3 = Rgs resistor, multiple references to the gate to source as a non-polarized capacitor and the need for a bleeder resistor to ground to aid in reliability of switch turn-off.? Value undetermined as yet.? My gut tells me R3 < R2, but I can't understand why I think that yet, exactly. ?? D1 = Protection for Pin #7 from 12 Vdc via bleeder resistor path.? Yes, I realize I put it in the circuit the wrong way... ? I really don't want to give up the forward voltage drop, but I can reduce the drop with a Schottkey, et al.? Reckon this extra protection is actually necessary enough to trade the 0.3+ volts or so? +5 VDC....? Don't know where I'm going to get this yet....? Don't really want to steal the FSK pin...? maybe the amp has a line 5 volt line I can steal. This device is getting bigger by the minute... the idea is to shrink it into the cable right behind the connector housing... IDEALLY, it would be better INSIDE the connector shell, but that's not going to happen.? May have to demo the circuit and then recreate it in SMD. 73, ______________________ Clay Autery, KY5G (318) 518-1389 From kevinr at coho.net Sun Jun 10 01:22:22 2018 From: kevinr at coho.net (kevinr) Date: Sat, 9 Jun 2018 22:22:22 -0700 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: <386a4ac7-6491-7b8d-aa7e-298883174e31@coho.net> Good Evening, ??

That depends a lot on where you live. Around Chicago and around NorCal, two places where I've spent a lot of time on VHF/UHF, most 2M and 440 MHz repeaters DO TX CTCSS tones. 73, Jim K9YC From KX3.2 at ColdRocksHotBrooms.com Sun Jun 10 16:38:42 2018 From: KX3.2 at ColdRocksHotBrooms.com (Lynn W.

Perhaps it *should* be... but some of the worst examples of wideband transmitted noise are caused by additional amplitude noise in the TX chain, or by poorly filtered DAC noise in SDR-based transceivers [1]. These noise sources are additional to the LO noise, and are present whenever the rig is in TX mode (even without modulation). That unfounded *belief* that "the LO phase noise should be pretty close" was precisely the reason why none of the designers paid any attention to the excess transmitter noise. But the equipment reviews were equally at fault for failing to draw attention to the problem.

Because I switch other things besides my amp. For example: Beverages disconnected from RX input during TX. Parasitic TX array elements (active during RX, to ground during RX).

Both are due to the new synth. The rest of the signal chain is also very clean. You have to get this right on both RX and TX to optimize for close-proximity, multi-transmitter operation (e.g. Field Day, DXpeditions, and big contest stations). 73, Wayne N6KR ---- http://www.elecraft.com > On Jun 10, 2018, at 12:55 PM, David Gilbert wrote: > > > I couldn't find any data on transmit phase noise on the Sherwood web site either, and I searched all over for it. > > Dave AB7E > > > >> On 6/10/2018 11:17 AM, Jim Brown wrote: >>> On 6/9/2018 12:54 PM, K9MA wrote: >>>> On 6/9/2018 14:52, David Gilbert wrote: >>>> I think another major concern for closely positioned rigs would be transmitted phase noise, and of course that doesn't show up in the Sherwood charts. >>> >>> Yes, it does! >> >> All I've ever seen from Rob is RX phase noise.

RP1 is aligned correctly, and I've verified that it is the correct part for this location. Worth mentioning is that the rubber spacer that installs onto the bottom-side of the board in the corner nearest pin 10 of RP1 is attached with a small drop of super glue (the original adhesive on the rubber pad failed, as the pad fell off during casual handling of the board). My understanding is that this cyanoacrylate super glue is non-conductive, nor does the spacer w/glue bridge any solder pads. I've not inspected the front panel board from the top, as this would require unsoldering the 4 leads holding the encoder board to the front panel board.

Since you have the new encoder board, it could be touching the pins on the back of the Control Board which can cause all kinds of "strange happenings". First step is to flush cut (diagonal cutters will not do the job) the pins on the encoder board (cut right down into the solder). Then flush cut the leads on the back of the Control Board where it can contact the encoder board. As an added protection measure, put a piece of card stock (business card of part of a QSL card) between the encoder board and the Control Board - or better yet a flat piece of plastic, like that used in many shrink wrapped packages from the store. Then see if the behavior settles down. If it does not, you will have to find the problem in the Front Panel switch matrix (not an easy task). 73, Don W3FPR On 6/10/2018 6:44 PM, Mark Petrovic wrote: > Don, the soldering on RP1 is very clean, top (viewed from the side of > the board with a light and magnifying glass) and bottom.?

I've not inspected the front panel board from the top, as this would require unsoldering the 4 leads holding the encoder board to the front panel board. >> >> > From donwilh at embarqmail.com Sun Jun 10 19:43:11 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 10 Jun 2018 19:43:11 -0400 Subject: [Elecraft] K2 BFO CW alignment question In-Reply-To: <01234BC6-8A73-4FE3-851A-C44ECA20D74A@gmail.com> References: <13f11a52-d396-30df-e331-e7cda324ca0b@embarqmail.com> <673fd1f3-df53-4025-31e3-b1fbe640dff7@embarqmail.com> <01234BC6-8A73-4FE3-851A-C44ECA20D74A@gmail.com> Message-ID: <0f03413b-a78c-1445-0d2e-eb4bdd162505@embarqmail.com> Mark, Analyzing the switch matrix is an iterative process The first thing to do is to determine which wrong responses are being sent, and for that you must refer to the schematic.? In your case of the REV button and the STP 60 display, the hold of the REV button is bringing up the PF1 display. Check the TAP function of the same button (AGC) to see if it brings up the RIT announciator (I think it will). If so, it means that the D1 and D2 lines are somehow being activated at the same time. Your first check would be to see if there is continuity between pins 12 and 13 of U2.? Also check for continuity to ground for both of those lines.? If you find U2 pins 12 and 13 shorted together, look for the reason - a solder splash making a bridge or a bit of wire lead stuck between the pins, look top and bottom of the board. That is how the process goes - as I indicated, it is not 'nice'. Hopefully those two buttons are the only ones involved. At worst, it means removing the pushbuttons and replacing them with new.? If it comes to that, clip the leads on the switch side close to the switch body and remove the leads one at a time, then troubleshoot the board. 73, Don W3FPR On 6/10/2018 7:15 PM, Mark Petrovic wrote: > Thanks, Don. > > Would you mind outlining the approach for analyzing the front panel switch matrix? > > > From kevinr at coho.net Sun Jun 10 20:38:40 2018 From: kevinr at coho.net (kevinr) Date: Sun, 10 Jun 2018 17:38:40 -0700 Subject: [Elecraft] Elecraft CW Net Report Message-ID: <5111c605-3569-ee23-6b19-c2bcc4b88784@coho.net> Good Evening, ??

I'll begin the debug process. By the way, I have eliminated spurious contact between the encoder board and control board, as I debugged that some weeks ago: https://www.mail-archive.com/elecraft at mailman.qth.net/msg219585.html. There is now room between the boards such that the plastic packing material you mention moves freely about without friction. This spurious contact possibility was one of the first things I checked today when the "c" indicator would not light.

We hope, like 2016, the District will not close due to fire restrictions. That year, I took my K3 to the NM DHS EOC and operated in a trailer with the ARRL SM and others. They used an IC-7600 for SSB and PSK while I operated just CW. We had a tri-band beam up about 35 ft. and an 80m OCF dipole about 50 ft. away which I used most of the time. If I tried to operate on the same band (different mode), the 7600 crashed. That rig desensed the K3, but I could continue to operate. I made more contacts than the SSB/PSK guys who operated more than I. A friend and fellow contester received his IC-7610 a few months ago to replace the IC-7600 he won years ago. Even on different bands, and with bandpass filters on my K3, the 7600 suffered some in RX sensitivity when we were on different bands. It will be interesting to see how his 7610 performs under similar circumstances when it comes back from Icom. Like many of them, it has an intermittent problem that drops TX/RX unexpectedly and sporadically! Due our to demographics, we will operate 1A again like, last year (21st in 1A) with a second K3 sharing antennas (triplexer and filters) for training/practice. We made 754 contacts, 73% CW, with five hours downtime due to lightning. In 2012 we operated three K3's and two K2's and placed 4th overall! We could operate two K3's and a K2 on 20m (SSB, GOTA, and CW) with NO inter-station QRM until the SSB rig's battery ran down. Somebody hit the surge suppressor switch, disconnecting the generator power. A CW op asked what changed. This is a good example why we run 14 VDC on the K3 for a cleaner signal and not 10 VDC. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From n6kr at elecraft.com Mon Jun 11 11:54:26 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Mon, 11 Jun 2018 08:54:26 -0700 Subject: [Elecraft] Field Day rig experience In-Reply-To: <1079707427.2801282.1528670792176@mail.yahoo.com> References: <1079707427.2801282.1528670792176@mail.yahoo.com> Message-ID: <5D0013A9-1F89-4880-B6C3-587DEF0BFD64@elecraft.com> Yes.

In contests like the IARU HF Championship, ARRL 10m, etc. where both modes are allowed, keeping appropriate bandwidth settings and the RX bandpass locations on the P3 would be very helpful! Yes, we can use a K-Pod or Genovation keyboard to do a lot, but I would rather keep what settings currently exist and change them only when I want to do so. I guess the first question is: is there enough memory in the P3 to do this. If so, where is something like this in the firmware improvement plan. If not, how difficult is it to upgrade the firmware memory size to accomplish this? In the meantime, I rarely run my K3 without the P3, even when I operate portable, like the upcoming Field Day. In the shack I use an SVGA monitor connected to the P3. I plan to replace it with a PIP monitor so I can switch from P3-1 to P3-2 in SO2R configuration. I often take P3 screenshots for stations with broad signals and to use in presentations. Combining the P3 with the KRX3 makes for a winning combination in many circumstances! 73, Bill, K8TE www.dukecityhamfest.org -- Sent from: http://elecraft.365791.n2.nabble.com/ From jim at audiosystemsgroup.com Mon Jun 11 13:20:16 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 11 Jun 2018 10:20:16 -0700 Subject: [Elecraft] Field Day rig experience In-Reply-To: <1079707427.2801282.1528670792176@mail.yahoo.com> References: <1079707427.2801282.1528670792176@mail.yahoo.com> Message-ID: <17c262a6-862c-9d4d-0a76-96b4e21a959c@audiosystemsgroup.com> On 6/10/2018 3:46 PM, Al Lorona wrote: > If you do take the icom, at 3.5A receive current drain you'd better take two extra batteries, too.

The internal keyer compensates for the increased TX delay. This works with both full break-in (QSK) and semi break-in. CW speeds above 37 WPM are badly distorted by jitter for both internal and external keying if you do not have a K3S or K3 with KSYN3A upgrade and CW QRQ mode is OFF. As noted previously, if you want a true TX DLY of 10 ms, set CONFIG:TX DLY to 13 (not 10). If you are using external keying from a WinKey or via serial port with CONFIG:PTT-KEY = OFF-DTR, with VOX ON, QSK OFF (semi break-in) and no PTT line closure, the first transmitted element will be truncated by the TX DLY setting (minus 2 or 3 ms assuming you have a K3S or K3 with KSYN3A upgrade). If using full break-in (QSK), *all* trnasmitted elements will be truncated for any value of TX DLY above 008 with external keying. Tcompensate for that, as mentioned previously, increase the length of every externally-keyed element by a fixed amount, using the WinKey "Keying Compensation" and/or "1st dit extension" setting. In the microHAM MK2R+ Router, it is now called "R/T delay", located on the Router's PTT tab (not the WinKey tab). None of this applies if you set CW QRQ ON. The TX DLY drops to about 4.5 ms, and CONFIG:TX DLY is ignored. None of this applies if your keyer or software holds the PTT line closed for the duration of a CW message. I have not made any measurements on an older unmodified K3 yet. 73, Bob, N6TV On Mon, Jun 11, 2018 at 12:36 PM, Lee Trout wrote: > With the talk on using older amps, it seems I recall there was distortion > introduced on CW if the delay was set to the higher end?

If you are using an OCFD antenna, a good balun plus a common mode choke at the feed point plus a common mode choke before the amp/radio is required.??

If running on batteries, that should be sufficient. If running on a generator, you COULD connect a heavy wire between the KXPA100 and the ground rod for the generator (do not drive a separate ground rod because it can cause an AC hazard). As for lightning protection, the normal Field Day precaution that I know is to disconnect antennas and turn off the equipment when that is nearby lightning. For your mobile installation, I don't think many mobile hams do any grounding. If you feel you need it, ground to the vehicle with a strap. A mobile station is "battery powered" and a ground is not normally needed. Remember that a ground is only for AC safety and lightning protection, and normally demands that a connection to Mother Earth is needed and that any extra driver ground rods must all be connected wwith heavy wire to the Utility Entrance ground rod. The only equivalent in a generator powered Field Day installation is a ground rod at the generator. There is no equivalent for mobile operation. 73, Don W3FPR On 6/11/2018 5:09 PM, Smedes, Tad - Comcast wrote: > I am planning to use my KX3 and KXPA100 powered by Budipole PowerMini > and LiFEPO4 battery for field day this year and have a question about > grounding.?

The K3 remembers the last-used frequency and mode on each band, so the two devices will (more or less) stay in sync. if this is provided. But I think it would be beter that time and the limited memory of the P3 be devoted instead to implementing the *often-requested USB mouse support*, so one can just point and click and fine tune the P3 and VFO with a mouse, like all other SDRs can currently do. Left click sets VFO A, right click sets VFO B, mouse wheel fine tunes the last click. Intuitive and fast. This would be so MUCH faster and easier than trying to use the tiny P3 knob and P3 cursors. Regarding macros, given the current P3 command set, one would need far too many P3 macros to set the scope edges of the P3 appropriately for every combination of band and mode, so this will be of limited value unless you only operate on a few bands and modes. But being able to run macros from the P3 buttons would be useful for other purposes. P3 Center Mode is of such limited value that I hope the P3 does NOT switch to Center Mode whenever I switch bands. Fixed Mode "HALF" has worked really well for me, since only the VFO cursors move, instead of the entire band. This should have been the P3 default, IMHO. But, this only works well after you have set up the P3's band edges. I've published Win-Test scripts to automated this. The Win-Test scripts control the P3 scope settings via simple text commands in the logging program. They can also be assigned to function keys. The scripts have knowledge of both the top and bottom frequency limits of every phone and CW sub-band, so they can intelligently set appropriate edges after reading the frequency of VFO A. You cannot do this in a K3 or P3 macro, because a macro cannot "read" the K3 frequency then do any math or complex logic on the returned value. To use the scripts from Win-Test, all you have to do is type SPAN60 [Enter], say, and the left and right edges of the scope are set to appropriate values, based on the current frequency and mode, e.g. 7.000 to 7.060 if VFO A was on 7.040 CW, or 7.125-7.185 if VFO A was on 7.130 LSB (USA phone sub-band starts at 7.125). See https://bit.ly/wtscripts and download P3scripts.zip (incluces source code). I am encouraging others to copy the same logic into their own logging software like N1MM+. In the mean time, since there's a free version of Win-Test, and since it can happily share access to the K3's serial port via OmniRig, you could use Win-Test only for setting the P3 scope edges, while using any other software like Writelog, WSJT-X, or HDSDR, software that supports OmniRig. N1MM+ and HRD cannot (and will not) support OmniRig, so they cannot be used at the same time as Win-Test, except via VSPE, COM0COM, ELTIMA or similar, but then proper interleaving of K3/P3 commands from multiple programs simultaneously may not be guaranteed. The free version of Win-Test is at http://download.win-test.com/v4/freeware/ . OmniRig may be downloaded from http://dxatlas.com/Download.asp. To get the most recent rig definition updates, be sure to download and extract the "INI files for OmniRig" to the "Rigs" sub-folder after installing OmniRig. I'll be happy to help anyone get Win-Test going with my P3 scripts, if you cannot figure out how to do it (hint: set radio type in Win-Test Interface Configuration to OmniRig, and read the Readme file inside P3scripts.zip). Contact me off list if you need help. 73, Bob, N6TV On Mon, Jun 11, 2018 at 11:03 AM, n6hz wrote: > Hi Bill, > > Currently the P3 stores span and reference level based on band, but not > mode.

The K3 internal keyer does not support a Cootie key - nor does it support Ultimatic mode for dual lever paddles that I have been asking for for years, but I solved the problem with a single lever paddle. 73, Don W3FPR On 6/11/2018 7:09 PM, KC6CNN wrote: > I just received my Begali HST III Key today. > I have it plugged into the paddle slot on my K3. > The single lever works great.

Nothing is easy! Linux mainstream versions such as Ubuntu and Mint are great systems - I run Mint dual boot with Win 10 here. That said, I use the Win 10 side for everything to do with my K-Line. I am spoiled, as are many others, by the ease of installation/operation of the software I use on a regular basis. Further, some software I use is not replaceable under Linux. There is nothing up to the job available. Wine is not the answer, as many Win programs will not properly run under Wine/Linux - if at all. Recently, there is also a problem with Wine itself - as being discussed on various Linux forums. Personally, I would much prefer to run Linux 100% - for various reasons (mainly security). That said, until Linux is made much more friendly to the new user and the available software library drastically increases, it will never be more than a very minor player at the user level. Linux is, however, a major player in higher levels.

Last year we really appreciated the KX3's ability to natively do PSK-31 as it let us operate without having to figure out how to power "real" computers. We take the class a step further than is strictly necessary by the rules: we avoid generators entirely (no AC power outlets available at the campground). *Everything* is on battery, which makes keeping laptops running a real challenge. We use android tablets for logging, and low-power Raspberry Pi Zero W as the central logging point. Last year we added in satellite contacts, something none of us had ever done before. It took until the last few minutes of the day on Sunday to make a satellite contact, but there was so much excitement after making it that the antenna and HT got passed around so everyone could give it a try on the next few birds that passed. This year I'm set on adding 6m and 2m. I'll definitely be pressing another KX3 into service on both bands, but plan to have two other power hogs on standby in case it feels like those extra 2 watts of RF on 2m might make a difference. -detrick K4IZ On Sat, Jun 9, 2018 at 12:49 PM, aj4tf wrote: > What are your Elecraft plans for Field Day?

This year, the event is to be held on Sunday August 19th. It will be a four hour sprint - from 17:00 UTC to 21:00 UTC (1:00 TO 5:00 PM EDT). QRP stations who wish to be designated as "Skeeters" can get a Skeeter number by requesting one by sending an e-mail to w2lj at arrl.net Please let me know if you intend to operate from a state other than your home state as listed on QRZ. Skeeter numbers will be issued from June 21st (the First Day of Summer) through the day before the event. Only Skeeter Number requests received by e-mail will be honored. This ensures that I will not miss anyone's requests, especially those requested via social media.(I tend to miss those!), This year's theme will be "water - the breeding ground for Skeeters!" Operate near any sizable body of water - lake, ocean, creek, river, bayou, stream, brook, pond, etc, for an extra 100 bonus points. As always the rules for the Skeeter Hunt can be found at http://www.qsl.net/w2lj/ Once June 21st arrives and Skeeter Number requests begin to be honored, the Official Roster can be found at https://docs.google.com/spreadsheets/d/1dac2DytXjH9fCHMeD0-Hzwd-lSKSE0yg3aWnw3NBB3M/edit#gid=1141920406 Follow us on Facebook at https://www.facebook.com/groups/175763746290252/?ref=bookmarks 72 de Larry W2LJ NJQRP Skeeter Hunt Manager From mspetrovic at gmail.com Mon Jun 11 22:53:42 2018 From: mspetrovic at gmail.com (Mark Petrovic) Date: Mon, 11 Jun 2018 19:53:42 -0700 Subject: [Elecraft] K2 BFO CW alignment question In-Reply-To: <0f03413b-a78c-1445-0d2e-eb4bdd162505@embarqmail.com> References: <13f11a52-d396-30df-e331-e7cda324ca0b@embarqmail.com> <673fd1f3-df53-4025-31e3-b1fbe640dff7@embarqmail.com> <01234BC6-8A73-4FE3-851A-C44ECA20D74A@gmail.com> <0f03413b-a78c-1445-0d2e-eb4bdd162505@embarqmail.com> Message-ID: I had an internal dialogue with myself as to whether I should reveal what the problem was, and concluded that I should.

I do wish it were better, but Linux seems to be steeped in "geekdom language" - if you are not educated in the language, you do not deserve to be part of our culture. Until Linux produces plain text language for errors and such messages, it will not be a major player in the computer operating systems. Windows has its share of cryptic messages, but at least it is in plain text and does not often refer to "gobbledygook" that is only understood by Windows geeks. I have tried Linux and have been stiffed by questions to the forums saying essentially "if you don't understand the language, go away". I am not a computer dummy - I understand DOS, but the Linux language is a thing unto itself. Ubuntu and Linux Mint have reduced the Linux install process difficulty, but have not tackled the cryptic messages that can result. If you only want to do only email and web surfing, then Linux can work well for you, but anything else can be daunting with cryptic requests to enter a nonsensical string of commands for "who knows what results" and be shamed by the forum geeks who blame you for not understanding the language. 73, Don W3FPR On 6/11/2018 11:00 PM, George Pasek wrote: > ./exec said: ./kx3util: error while loading shared libraries: > libstdc++.so.6: cannot open shared object file: No such file or directory > > Add Arch support > ? sudo dpkg --add-architecture i386 > Followed by > ?? sudo apt-get update > ??

Let's use the right words for the right things we do.? BONDING is what we are doing when we may an electrically short and mechanically robust connection between equipment and between all of the grounds in our home.? GROUNDING is a connection to Mother Earth. It's purpose is Lightning Protection. > When I use my KX3 by itself mobile I have never grounded it and never > had an issue. In general, radio equipment should be bonded together, but should NOT be bonded to the vehicle. You MUST run a pair of big wires direct from the battery to the rig. NEVER use the vehicle chassis as a path for return DC current -- that's a recipe for disaster!? The only connection to the vehicle should usually be the coax shield to the best metal you can find at the antenna, because the metal in the car body acts as the counterpoise for your antenna. In other words, it is PART OF the antenna!? Make sure that whatever metal you bond to actually goes to the rest of the car's chassis. That's often not easy -- even when there are metal to metal mechanical connections, they're often insulated from each other by paint! > Is there anything special that I need to do do when I hook the KX3 to > the KXPA100 while mobile, and what is it? and or what do the rest of > you do when running mobile with a KX3 and KXPA100 for grounding? 73, Jim K9YC From rv6amark at yahoo.com Tue Jun 12 02:42:20 2018 From: rv6amark at yahoo.com (Mark) Date: Mon, 11 Jun 2018 23:42:20 -0700 Subject: [Elecraft] KX3 Utility Linux version Message-ID: Re:??

Since the 7610 doesn't have a front-end either, I imagine that it will do the same. Sherwood himself notes that using the SDR radio (i.e, without a superhet front-end) means reducing gain to limit ADC overload, but he has also suggested that blocking dynamic range is over-rated. Generally this is true, dynamic range is over-rated if you are using one radio. However, blocking isn't over-rated in a field day situation (more than one radio) or if you have a neighboring op running high power, or in legal-limit multi-op situations (with antennas relatively close to each other), or in legal-limit so2r. Reducing sensitivity works to prevent ADC overload on the lower bands where sensitivity is not needed in the first place but on 15m through 6m one can use the sensitivity. While SDR radios have their advantages, some of the advantages of superhet radios still exist today, namely, that a so-called roofing filter front-end (which is just a mode-specific filter ahead of the first mixer) will deliver outstanding blocking AND as much sensitivity as required (compared to SDR). I don't see any way around this fact (at least not yet) and you can see the difference in the Sherwood numbers. 73, Will, wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Sat, 6/9/18, Wayne Burdick wrote: Subject: Re: [Elecraft] Field Day rig experience To: "Bill" Cc: "Elecraft Reflector" Date: Saturday, June 9, 2018, 10:34 AM > On Jun 9, 2018, at 5:24 AM, Bill wrote: > > Along the line (lightly discussed under "K3- AF Knob") of what rigs are used for dxpeditions and Field Day......? How do the new technology ICOMs (7300 and 7610) do under the "several rigs on the same band" conditions? The size, weight, and cost factor is inviting for the 7300 - BUT!!! Is it up to the job? Close to up to the job? Or, better left home during these events? Hi Bill, Hopefully you?ll get some responses to this question from those with direct experience. But looking at it theoretically: both the 7300 and 7610 are direct-sampling radios with about 25-30 dB less blocking dynamic range than the K3 or K3S. On Field Day this could have a definite impact when using multiple transmitters on the same band, or even on different bands, depending on antenna spacing and power level used. Dynamic range of all of these radios is quantified in the receiver performance table at www.sherweng.com, specifically the fifth column (?100 kHz Blocking?).

This would include verticals like the Cushcraft R8. These do require a ground for static discharge protection. But, as Jim, K9Y, has pointed out numerous times, this ground is NOT for the antenna's operation/radiation. Buy Ward Silver's, N0AX, book on Bonding and Grounding, if you can find it. Jim's web site is free! Don's advice on lightning is paramount for safety! If lightning is within 10 miles, disconnect all antenna cables, and enjoy your food, beer, reading material, etc. We had two Airmen killed at Canon AFB NM when this requirement was ignored. Disconnecting antennas during last year's FD for five hours dropped us out of the Top 20 in 1A by one! However, unlike two years previous, we suffered not equipment damage and, most importantly, no operator damage. Sadly, the Cibola National Forest just announced it will close down (about 95%) this Friday due to extreme fire danger. I am seeking an alternative that meets our criteria. An EOC sounds enticing.

As to connecting to mother earth, it is the antenna that works against earth.? Thus if you are using a center fed dipole, no mother earth connection is needed.?? If you are using an OCFD antenna, a good balun plus a common mode choke at the feed point plus a common mode choke before the amp/radio is required.?? If you are using a vertical or inverted L, then a real ground system with radials is required for the antenna to work against.? If you are using a random length of wire thus end fed, then a real ground system is needed.?? A single? driven ground rod IS NOT a good ground system for any antenna.

A small nit... perhaps my ignorance... but, I think that the roofing filter [by whatever name] comes after the first mixer, at the so-called IF frequency. Your points are well made. I think the far out SDR's speak more to what can conceivably be done versus what's the design approach that best meets a broad range of desirable receiver parameters. Elecraft seems to have found the sweet spot in the battle of trade offs. ...robert On 6/12/2018 15:49, WILLIE BABER wrote: > More then one so2r operator has noted that the 7300 will overload in an so2r situation so that you cannot clearly hear on 7300 when the other radio is transmitting (yes, on a different band). Since the 7610 doesn't have a front-end either, I imagine that it will do the same. Sherwood himself notes that using the SDR radio (i.e, without a superhet front-end) means reducing gain to limit ADC overload, but he has also suggested that blocking dynamic range is over-rated. Generally this is true, dynamic range is over-rated if you are using one radio. However, blocking isn't over-rated in a field day situation (more than one radio) or if you have a neighboring op running high power, or in legal-limit multi-op situations (with antennas relatively close to each other), or in legal-limit so2r. > > Reducing sensitivity works to prevent ADC overload on the lower bands where sensitivity is not needed in the first place but on 15m through 6m one can use the sensitivity. While SDR radios have their advantages, some of the advantages of superhet radios still exist today, namely, that a so-called roofing filter front-end (which is just a mode-specific filter ahead of the first mixer) will deliver outstanding blocking AND as much sensitivity as required (compared to SDR). > > I don't see any way around this fact (at least not yet) and you can see the difference in the Sherwood numbers. > > 73, Will, wj9b > > CWops #1085 > CWA Advisor levels II and III > http://cwops.org/ > > -------------------------------------------- > On Sat, 6/9/18, Wayne Burdick wrote: > > Subject: Re: [Elecraft] Field Day rig experience > To: "Bill" > Cc: "Elecraft Reflector" > Date: Saturday, June 9, 2018, 10:34 AM > > > > On Jun 9, > 2018, at 5:24 AM, Bill > wrote: > > > > Along the > line (lightly discussed under "K3- AF Knob") of > what rigs are used for dxpeditions and Field Day......

Most distros have it pre-installed, but not all. It is easy to install from a terminal: sudo apt-get install curl 3) Ensure your DialOut groups are set up properly Most users, other than root and members of the dialout group, do not have read/write permissions on the serial port device files. The Utilities cannot access the serial ports if the user does not have r/w permissions. An easy way to set the permissions is to add the user to the dialout group. sudo adduser username dialout 4) All files and directories included in the gzipped tar file must be kept together in the same location.

Look into the linuxham at groups.io mailing list (the home of Fldigi etc) Lots of GOOD help on there, by many who remember our initial frustration with it all. (Some Elecraft users there too.) As to one OS vs another. Linux is different, that is all. Do any of you remember when you first started using Windows or Mac*? I'll bet that was just as frustrating and confusing then, as if you expect to "just jump in, and survive" with Linux (or BSD, or MacOS) these days. (* Has to be said, that back in the Steve Jobs days, the UI was truly a work of art, you didn't need instructions. Since his sad demise, it's all gone a bit Pete Tong.) As others have said, it is possible to have a PC that will boot it's original OS (Windows or Mac) or one or more versions of Linux (or any other OS) so you can choose at boot time what you want. Yes, there are several well known Ham Radio programs that have no "Direct equivalent" Linux version, but there is other equaly good software native to Linux that will do the same job. Mostly. There are also some that have no equivalent, or even anything close (sadly.) Some of them will run under WINE, some wont. But, unless you use them all the time every day, you won't need them most of the time. (Thinking here of Motorola DMR programming software as an example.) In such cases, just boot into Windows, get that job done, then if needed reboot back into Linux (or whatever) and carry on. If you want to just get your toes wet, without risk of corrupting or bricking your main PC, get another, or even a Raspberry Pi, to experiment on. The Pi's are good, as the whole OS etc fits on one SD card. If you mess it up, it's trivial to wipe and start over. The latest Pi's are really good and powerful machines too, much more than you'd expect from something of it's size, and at the price, can't be beat. Dont give up. Keep moving. Explore the pre-built packages first, before trying to learn how to compile stuf from source. But when ready, get onto the Fldigi wiki, and follow the build instructions there, to build and install the latest Fldigi etc. http://www.w1hkj.com/doku/doku.php?id=start If needed, ask on linuxham.io for assistance, and it will be given. 73.

In the K3/K3S, we have a very strong mixer and post amp followed by crystal filters at the first I.F., 8.215 MHz. Since the IF and ADC are down-stream from these filters, they are very well protected from out-of-band signals. Our crystal filters are manufactured to very tight tolerances and as a result, provide consistently high dynamic range. The P3 panadapter gets its signal ahead of the crystal filters so it can display a wide spectrum. It is in effect a direct-sampling SDR in its own right. The beauty of having the panadapter?s receiver chain (P3) fully separate from the demodulation receive chain (K3) is that demodulation remains unaffected (up to very signal levels) even if the panadapter has to separately reduce its own gain. ?Pure? SDRs (IC7300, IC7610, Flex) don?t have this luxury; everything runs from the same wideband ADC, without narrowband protection via crystal filters. Another K3/K3S advantage is in its very narrow ham-band RF filters. These are positioned ahead of the P3 pickoff point, benefitting both the panadapter and demodulation channels. 73, Wayne N6KR > On Jun 13, 2018, at 11:38 AM, WILLIE BABER wrote: > > Robert is talking about the crystal filters, also known as roofing filters now-days, that are typically placed after the first mixer (I mistakenly typed "ahead" but I meant "after" as Robert notes), though there is a post amp and NB before these filters in K2 and K3. > > The idea is that a crystal filter right after the first mixer gives high dynamic range because high selectivity comes before the receiver has developed stages of gain that otherwise could cause blocking or IMD, especially when selectivity is postponed to the second mixer while ignoring gain distribution in prior stages of the receiver.

I did NOT know that. I DID know you can use 20A/120V * outlets on 15 Amp circuits, but I hadn't heard about the breaker spec down-grade as well. I recently changed out all my kitchen outlets to the 20A * type mainly just to get a heavier duty outlet. The code called for two separate 20A/12ga circuits in any kitchen which is what I used when I wired the house in 1974. The socket we use for a typical coffee maker recently felt too warm after brewing a pot, so after 40+ years, I felt it was time for a new socket anyway, so why not go with the heavier ones. Of course, I may be fooling myself as the size of the actual brass used in them MAY be the same as the regular 15A outlets. 73, Charlie k3ICH *In 20A/120V outlets, the neutral side (white wire terminal) can accept either the normal 15A parallel blade plug, or the 20A version where the neutral blade is perpendicular to the hot (black) blade.

Both designs are using the idea of "roofing filter" to refer to up-conversion radios similar to the use of up-conversion 3khz filters as roofing filters in Icom radios. "Roofing filter" (a mode specific filter after the first mixer including narrow cw filters) only makes sense in the context of the history of superhet design and in particular the use of one broad 15 khz first I-F (so that all modes may pass through it) typical of all Japanese radios until recently. Calling a 45 mhz filter at the first I-F a "roofing filter" as noted in the info you sent entirely misses the point of what roofing filter means. Or, to put it another way, all Ten-Tec radios had roofing filters in them (and were ssb and cw only) well before the term roofing filter was coined! Which is why an Omni C will out perform any wide (15 khz) first I-F Japanese radio, even those built well after the 1980 vintage Omni C. Unless mode specific up-conversion crystal filters can be made and as narrow as 200 hz (this is possible with down-conversion) then "roofing filter" and up conversion doesn't make sense historically or in reality. Actually, Icom says that did it with 1.2khz filter at 64 mhz in the Icom 7851, though I'm not convinced the filter is that narrow, and 1.2khz is far from the 200hz filter that my K3 has in it (however, the placement of this filter is why the 7851 is among the best radios in Sherwood's chart, on cw). It is possible to make very narrow and precise crystal filters as narrow as the 200 hz inexpensively, and this is the point of having multiple roofing filters at the first I-F. So, this is the origin of the term roofing filter---in comparison to the barn-door up conversion first I-F. 73, Will, wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Wed, 6/13/18, Wes Stewart wrote: Subject: Re: [Elecraft] Field Day rig experience To: elecraft at mailman.qth.net Date: Wednesday, June 13, 2018, 3:08 PM Certainly not to disparage the K3(S) architecture (I have two of them) there is nothing inherently wrong with an up-conversion receiver, if modern hardware is used.

You're correct about code and safety. Bigger wire has less loss and will stay cooler. Inspectors may look at a job, see a 15 amp breaker and yellow NM, and insist on the "correct size" breakers, and the "correct" 15/20A outlets. Sadly, code is often what the local inspector thinks it is. 73 -- Lynn On 6/14/2018 8:53 AM, Phil Kane wrote: > You can always/undersize/ the breaker - the code specifies*maximum* > current for the wire size.

Message-ID: "Will 15A house line supply enough juice for the K3S, KPA500, KAT500, and in the future a P3 Panadaper?" When I added my KPA500 to my TS-590S station I found the drop in mains voltage unacceptable. I made some changes in power distribution and now have a web power switch connected directly to the 120 V outlet. That web power switch feeds the KPA500 directly and feeds the other station equipment via breakout strips. One port of the web switch has a permanently installed "kill-a-watt" monitor. The outlet I'm plugged into is just the other side of the house wall from the breaker panel. With this power distribution arrangement I run my KPA500 at 500 W output and PA voltage does not usually drop below 60 V. In a spot check on 20 m (the band at which my KPA500 efficiency seems to be worst) I saw 119.0 V with KPA500 standby and 113.4 V with key down 500 W RF output. The situation is a bit worse when the heat pump is running but doesn't seem to cause any operational problems. If I ever build a real station I'll include 240 V outlets. 73, Andy k3wyc From jim at audiosystemsgroup.com Thu Jun 14 13:39:16 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 14 Jun 2018 10:39:16 -0700 Subject: [Elecraft] power requirements for a K3S, KPA500, KAT500, P3?

No power reduction is required -- let's do the simple math. The KPA draws about 10A at 120v keydown. That 12v (probably 13.8V) supply shouldn't draw much more than about 2A when the K3 is driving the KPA500, because the KPA needs less than 30W to get to full power. The 13.8V supply should draw no more than about 2A with the K3 barefoot at full power keydown. 73, Jim K9YC From jim at audiosystemsgroup.com Thu Jun 14 13:48:47 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 14 Jun 2018 10:48:47 -0700 Subject: [Elecraft] AC Power for the Station In-Reply-To: <0c8686de-018a-f464-2bd7-45e97607779f@ColdRocksHotBrooms.com> References: <024801d4038a$5448bbd0$fcda3370$@gmail.com> <7172e3b3-d178-8ac6-0d29-8e27a0d1d187@audiosystemsgroup.com> <012d01d40390$b91d0dd0$2b572970$@erols.com> <5B21EE6E.10420.BD8E0BB@john.johnjeanantiqueradio.com> <001c01d403db$10199460$304cbd20$@erols.com> <7c83625e-bbb3-57e1-af25-c0d6c9e1e3e3@blomand.net> <0c8686de-018a-f464-2bd7-45e97607779f@ColdRocksHotBrooms.com> Message-ID: <330453eb-6583-82ff-9251-ebfeff1944e4@audiosystemsgroup.com> On 6/14/2018 8:47 AM, Lynn W.

The 13.8V supply should draw no more than about 2A with the K3 barefoot at full power keydown. > > 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 hsherriff at reagan.com From wa6nhc at gmail.com Thu Jun 14 14:06:09 2018 From: wa6nhc at gmail.com (Rick WA6NHC) Date: Thu, 14 Jun 2018 11:06:09 -0700 Subject: [Elecraft] AC Power for the Station In-Reply-To: <330453eb-6583-82ff-9251-ebfeff1944e4@audiosystemsgroup.com> References: <024801d4038a$5448bbd0$fcda3370$@gmail.com> <7172e3b3-d178-8ac6-0d29-8e27a0d1d187@audiosystemsgroup.com> <012d01d40390$b91d0dd0$2b572970$@erols.com> <5B21EE6E.10420.BD8E0BB@john.johnjeanantiqueradio.com> <001c01d403db$10199460$304cbd20$@erols.com> <7c83625e-bbb3-57e1-af25-c0d6c9e1e3e3@blomand.net> <0c8686de-018a-f464-2bd7-45e97607779f@ColdRocksHotBrooms.com> <330453eb-6583-82ff-9251-ebfeff1944e4@audiosystemsgroup.com> Message-ID: <7e7ed91f-e0ea-71ad-221e-3c2b0935ef8c@gmail.com> As a retired career firefighter (line Captain), I say: A POX on the push in connections.?

Remember that there's a three-position jumper that selects a transformer tap inside the amp to adjust for line voltage. Access it by removing the top cover, and RTFM to learn how to set it. Unplug from power, of course. The KPA will go into protect mode if the HV is too high when NOT transmitting (greater than about 82V) and too low when transmitting (less than about 55V), so the key is to watch that voltage after changing the jumper. We run two K3/KPA500 for 7QP and CQP county expeditions from two Yamaha 2000i generators, which are providing 120V. We're running about 40 ft of #10-3 from the generator to the outlet where the amps are plugged in, and typically get 500W from the amp. Team leader W6GJB bought a "strapping kit" to run the generators in parallel, and changed the breaker on the one feeding the station to 30A. We do this for the generators -- they're happier in parallel with keyed CW. 73, Jim K9YC From elecraftcovers at gmail.com Thu Jun 14 14:30:28 2018 From: elecraftcovers at gmail.com (Rose) Date: Thu, 14 Jun 2018 12:30:28 -0600 Subject: [Elecraft] AC Power for the Station In-Reply-To: <7e7ed91f-e0ea-71ad-221e-3c2b0935ef8c@gmail.com> References: <024801d4038a$5448bbd0$fcda3370$@gmail.com> <7172e3b3-d178-8ac6-0d29-8e27a0d1d187@audiosystemsgroup.com> <012d01d40390$b91d0dd0$2b572970$@erols.com> <5B21EE6E.10420.BD8E0BB@john.johnjeanantiqueradio.com> <001c01d403db$10199460$304cbd20$@erols.com> <7c83625e-bbb3-57e1-af25-c0d6c9e1e3e3@blomand.net> <0c8686de-018a-f464-2bd7-45e97607779f@ColdRocksHotBrooms.com> <330453eb-6583-82ff-9251-ebfeff1944e4@audiosystemsgroup.com> <7e7ed91f-e0ea-71ad-221e-3c2b0935ef8c@gmail.com> Message-ID: Well said, Rick! 73!

If I were to discover them in any house I occupied, I would pull the wires out of the 'backstab' and put the wires under the screws. There is nothing wrong with the receptacles, except for that marginal wire contact in the 'backstab' contacts - change those to "under the screw" connections and all will be well. There are good 'strip and insert' receptacles use a clamping mechanism tightened with a screw, and those do not have the problem. My house is wired with #12 wire for ALL the receptacles, (lighting is #14) but I do use the 15 amp receptacles with no problem (except in the kitchen where they are 20 amp) - the 15 amp receptacles will not accept #12 wire in the 'backstab' holes, so the only choice was to use the screw terminals. I have 20 amp breakers on the receptacle circuits, but 15 amp on the lighting. Yes, I did it myself and the inspector had no problem with my wiring. 73, Don W3FPR On 6/14/2018 9:07 AM, Bob McGraw K4TAX wrote: > And in replacing receptacles, I found the original 1980 wiring in our > house was done by the "strip and push-in" connections.??

For what it's worth, I find it interesting how the term "Roofing filter" has changed a bit over time and with different 'ownership'. Personally, I first came across the term in around 1966 as a junior design engineer working on the Redifon R550 series of HF receivers. I understood then that the term "roof" referred to the "top of the house" filter used to provide the first measure of protection against adjacent unwanted signals. These and other similar HF receivers used an up-conversion architecture, and the R550/551 employed a first IF at 38 MHz with the local oscillator running 38 to 68 MHz. The bandwidth of this filter, which followed the first mixer, was around 15 KHz as I recall. The second IF was at 1.4 MHz (or 1.6 MHz in other similar designs) and featured a number of selectable crystal filters typically providing close-in band-widths from around 200Hz to 12 KHz. Employing a first IF above 30 MHz shifts the first image into the VHF spectrum and allows the use of a 30 MHz low pass filter in the front end, with sub-octave band pass filters to provide a measure of front-end selectivity. We would have loved to provide close-in selectivity at the first IF frequency and so avoid a down-conversion to the second IF, but achieving the required passband /stopband characteristics just was (is) not possible at 38 MHz. However, decent close in selectivity (passband and stopband) can be provided with crystal filters at around 9 MHz or thereabouts, and many of the earlier purely analogue designs of amateur equipment took advantage of this, including TenTec. I do not personally view this particular application as a roofing filter as is not protecting further stages of selectivity.t it All now ancient history...things have moved on a bit since then! Can anyone trace the term further back in time? However, It seems to me that the term "roofing filter" still makes perfectly good sense in the context of the K3 design, with the selectable crystal filters providing the maximum possible (mode dependent) selectivity protection in front of the final IF, even if that is now implemented using DSP techniques! Terry G3VFO -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of WILLIE BABER Sent: 14 June 2018 16:02 To: elecraft at mailman.qth.net; Wes Stewart Subject: Re: [Elecraft] Field Day rig experience Hello Wes, I took a look. Both designs are using the idea of "roofing filter" to refer to up-conversion radios similar to the use of up-conversion 3khz filters as roofing filters in Icom radios. "Roofing filter" (a mode specific filter after the first mixer including narrow cw filters) only makes sense in the context of the history of superhet design and in particular the use of one broad 15 khz first I-F (so that all modes may pass through it) typical of all Japanese radios until recently. Calling a 45 mhz filter at the first I-F a "roofing filter" as noted in the info you sent entirely misses the point of what roofing filter means. Or, to put it another way, all Ten-Tec radios had roofing filters in them (and were ssb and cw only) well before the term roofing filter was coined! Which is why an Omni C will out perform any wide (15 khz) first I-F Japanese radio, even those built well after the 1980 vintage Omni C. Unless mode specific up-conversion crystal filters can be made and as narrow as 200 hz (this is possible with down-conversion) then "roofing filter" and up conversion doesn't make sense historically or in reality. Actually, Icom says that did it with 1.2khz filter at 64 mhz in the Icom 7851, though I'm not convinced the filter is that narrow, and 1.2khz is far from the 200hz filter that my K3 has in it (however, the placement of this filter is why the 7851 is among the best radios in Sherwood's chart, on cw). It is possible to make very narrow and precise crystal filters as narrow as the 200 hz inexpensively, and this is the point of having multiple roofing filters at the first I-F. So, this is the origin of the term roofing filter---in comparison to the barn-door up conversion first I-F. 73, Will, wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Wed, 6/13/18, Wes Stewart wrote: Subject: Re: [Elecraft] Field Day rig experience To: elecraft at mailman.qth.net Date: Wednesday, June 13, 2018, 3:08 PM Certainly not to disparage the K3(S) architecture (I have two of them) there is nothing inherently wrong with an up-conversion receiver, if modern hardware is used.

That said, by the generally accepted definition, you are wrong. See Elecraft's take on this: http://www.elecraft.com/K3/Roofing_Filters.htm If you will think in Wayne's terms, the post-mixer filter is a "protective" filter, not a mode-specific filter.? So the question becomes, how much protection is necessary?? In Elecraft's case, quite a lot, IMHO.? With its QRP DNA, Elecraft uses post crystal filter circuitry that minimizes current consumption.? The trade off for this is the need for a bank of pricey crystal filters to limit the frequencies that the circuitry is exposed to. Now what if the subsequent circuitry doesn't require this much protection because it is more robust?? We now have direct-sampling radios that can digitize a whole ham band with good performance. If the BW was limited to 10-15 kHz in an up conversion configuration they should be even better.? The limitation now becomes LO phase noise, but newer synthesizer designs overcome that obstacle.? Another thing to note is that IMD in crystal filters is reported to be inversely proportional to BW. So a wider filter might actually be better from that perspective.? Some Elecraft filters exhibit passive IMD BTW. Wes? N7WS On 6/14/2018 8:01 AM, WILLIE BABER wrote: > Hello Wes, > > I took a look.

Here's a weird one: Two years ago, I bought a house that had been built in 1980, by the folks that I bought it from. No intermediate owners. Wired with copper wire (not aluminum). I'm replacing many of the AC receptacles because they are so loose that a plug falls right out of them. I've never seen that before. My previous house was built in 1970, and never had that receptacle problem, or in any other house I've ever lived in. Maybe a bunch of cheapy ones?

The narrower this filter is, the less exposure later stages will have. Thus a "narrow" roofing filter is desirable -- but "narrow" is relative, as I'll explain." What Elecraft said (above) is exactly what I said. Moreover, Elecraft's explanation is required because the term roofing filter is now applied to up-conversion in multiple conversion radios (with relatively wide first I-F filters compared to what is achievable at a low first I-F) which is what the term initially sought to rebuff in the first place, also my point. 73, Will, wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Thu, 6/14/18, Wes Stewart wrote: Subject: Re: [Elecraft] Field Day rig experience To: elecraft at mailman.qth.net Date: Thursday, June 14, 2018, 4:47 PM Will, First of all I have said before and will repeat it, I detest the term "roofing filter."?

(Wayne can correct me if I'm wrong.)? One, of course, is to reject the image of the second IF.? However, the dynamic range of the ADC in the second IF, by itself, just isn't enough to provide the 140 or so dB we need.? The combination of the ADC/DSP and the crystal filter does the trick, even though 8 MHz crystal filters aren't all that great.? As I recall, there were some earlier DSP only receivers, but their dynamic range was poor. Crystal filters are expensive, but until we have fast ADC's linear to at least 24 bits, they're necessary to get that kind of dynamic range. I've often wondered if any other communication system requires the close in dynamic range we do.? Why would anyone design a system that allowed signals 2 kHz apart to differ in strength by 140 dB? 73, Scott K9MA On 6/14/2018 20:33, WILLIE BABER wrote: > Wes, > > "A "Roofing filter" is simply a filter in the radio's first IF through which all signals must pass before they will be "seen" by later receiver stages.

And so end of thread. ----------------------------------- What "Roofing Filter" means to Elecraft There's been so much discussion about this topic that I'd thought I'd better try to clarify why we used the term when discussing the K3S. A "Roofing filter" is simply a filter in the radio's first IF through which all signals must pass before they will be "seen" by later receiver stages. The narrower this filter is, the less exposure later stages will have. Thus a "narrow" roofing filter is desirable -- but "narrow" is relative, as I'll explain. The term "roofing filter" has most often been used in relation to triple- or quadruple-conversion receivers. Such receivers have an? IF above the highest RF band covered; it's typically something in the range of 30 to 70 MHz or higher. But "roofing" as a term should be interpreted as "protective," not "high in frequency." A roofing filter protects later stages, including amplifiers, mixers, narrower filters, and DSP subsystems, just as the roof on your house keeps rain out of all of the rooms. But a roofing filter can be equally at home at a low first IF, if that is how the radio is designed. It still provides the same protective function. When we released the K2 in 1999, we never described our 1st IF crystal filters as roofing filters. We had only one IF, so the receiver model was simpler; there were no narrow filters at later stages that required protection. But now, we find that the term is in widespread use. Average hams now think of roofing filter bandwidths as the standard of comparison between receivers. This is why manufacturers have jumped through hoops to try to provide the narrowest possible roofing filters. Many operators have an understanding (justified) that a roofing filter that is wider than the communications bandwidth will not best protect the receiver's later stages. So the term now seems appropriate to use even in a radio such as the K2, K3S, or Orion, all of which use low-frequency IFs (5 to 9 MHz). In recent years, the roofing filter has become the centerpiece of receiver redesign: Suppose that manufacturer "A" initially designed their receiver to use a 15- or 20-kHz roofing filter. Yes, this allows the receiver to handle NBFM and other wide modulation modes; it may also be selected to constrain the signal bandwidth ahead of a noise blanker or spectrum scope. But it comes at a price. If you're using CW mode, you'll have much narrower filters selected at the radio's 2nd and 3rd IFs. Yet the 1st IF roofing filter allows a broad swath of signals into the earlier stages. You don't need this energy in your passband. It can cause trouble. Manufacturer "A," realizing they have a problem with dynamic range at close spacing, then announces that they've had a breakthrough: they can now offer a 6-kHz, or more recently 3-kHz roofing filter. This will certainly improve the situation for SSB and AM operation, but it still opens the barn door in CW or DATA modes, because the bandwidth is a factor of 10 wider than needed for communications.? So why don't they offer much narrower roofing filters that can be switched in for CW and data modes, or at times when adjacent-channel SSB QRM is very high? It's because they can't make filters any narrower at such a high IF. Enter the "down-conversion" rig (K2, K3S, Orion, etc.). By converting to a low first IF, the designer can easily create narrow filters that are compatible with the required communications bandwidth. This is why we are offering filters with bandwidths as low as 200 Hz. And yes, these are still "roofing" filters, because they limit exposure (bandwidth), thus protecting later stages (in the K3S case, the IF amp, 2nd mixer, and DSP). 73, Wayne N6KR CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Thu, 6/14/18, K9MA wrote: Subject: Re: [Elecraft] Field Day rig experience To: elecraft at mailman.qth.net Date: Thursday, June 14, 2018, 8:28 PM There are at least two excellent reasons for the narrow crystal filters in the first IF of the K3(s).? (Wayne can correct me if I'm wrong.)? One, of course, is to reject the image of the second IF.? However, the dynamic range of the ADC in the second IF, by itself, just isn't enough to provide the 140 or so dB we need.? The combination of the ADC/DSP and the crystal filter does the trick, even though 8 MHz crystal filters aren't all that great.? As I recall, there were some earlier DSP only receivers, but their dynamic range was poor. Crystal filters are expensive, but until we have fast ADC's linear to at least 24 bits, they're necessary to get that kind of dynamic range. I've often wondered if any other communication system requires the close in dynamic range we do.? Why would anyone design a system that allowed signals 2 kHz apart to differ in strength by 140 dB? 73, Scott K9MA On 6/14/2018 20:33, WILLIE BABER wrote: > Wes, > > "A "Roofing filter" is simply a filter in the radio's first IF through which all signals must pass before they will be "seen" by later receiver stages.

Inventory the inductor bag contents separately as well - there is a 1mH RF choke that looks very closely like a 1k resistor. If you are not adept at identifying screw sizes, measure them (they are all 4-40 diameter). The best method of keeping the parts organized is to use the old "Heathkit" method. Seal up an empty USPS Priority Mail Medium Flat Rate Box (the 13.5 x 12 x 3.5 inch size) and you have 2 'trays' with cardboard corrugation on both sides. Stick the component leads in the corrugations. The center of the tray can be used to hold the larger items and hardware. I personally do not like muffin tins or plastic boxes for the hardware because I cannot get my fingers in to grasp them easily, but some folks seem to like to use them. 73, Don W3FPR On 6/15/2018 10:45 AM, Scott wrote: > I'll be starting a K2 build in the near future after the inventory is > complete.?

Here's a couple of things that might help you along: It's not one kit it's 3. Think of it like that and keep everything separate. Even though you will do a minimal build on the RF board for test purposes it's still 3 kits. It's not a one day build. Even if you spend every waking hour on it (you wont!) it still takes a fair few days/weeks/months to get through. The book is right! Even when it's just plain wrong, it's right. Go back read it again, ask on here. But that build book must have been worked over almost 8000 times, it's right. I couldn't find any suitable trays to organise components but I bought a set of small(ish) plastic pots with lids. Big enough to get my fingers in. I had 12 I think which was more than enough, about 4 inches diameter and a couple of inches deep. Keeping the lids on and marked with the contents helped keep from them scattering from a careless movement or other accident. Keep everything as Elecraft intended. If it came in a separate little brown envelope, inventory it then put it back in the envelope. Keep the resistors on their tapes, they are in fitting order. Get a good quality pair of flush cutters and learn how to use them. It's worthwhile perfecting the technique of close cutting the leads before soldering, makes a nice board to handle afterwards and is very very very necessary in the area of the main vfo encoder. Ask questions here, it's a fantastic resource. Last, but by no means least, enjoy! As the ads say, it's the most fun you have with your clothes on. Though that might depend on how you do your kit building :) 73 Martin, HS0ZED On 15/06/2018 21:45, Scott wrote: > I'll be starting a K2 build in the near future after the inventory is > complete.?

So there would be an entire reel of 10k resistors, a separate reel of 100k, separate reel of diodes, etc. The sequencer then removes the parts from the tape and creates a new tape with the parts in the proper order and count.?

I think that's pretty good for an SS Amp. I also measured the gain on all the bands at 1.5KW out. Drive varied from 31W on 80M to 47W on 15M. or 16.8dB to 15.0dB. That amount of variation is rather disappointing. I also noted that the internal power meter is pretty inaccurate at low levels. For Example at 50W on 20M it reads 43W. Its pretty close above 300W and right on at 1.5KW where its calibrated.

I agree with all the previous advice, I picked up another 40 drawer parts cabinet for the parts, used them both,? and kept them in order that way.? Each board had its own area of the cabinets,Packing Box bag in one area,? Control Board in the next, RF board in another, etc.? I then segregated the parts by type. All the capacitors in one section, either by the PCB board number, or in the case of the '102' and '103' capacitors, all in one drawer and grabbed them as needed.??? Marked them across the front of the drawer with a Sharpie and masking tape. My resistors came all taped ready to go in order, just find the right end of the 'string' and work from there.?? Verify the colors, but it will save you a lot of time searching for the next resistor. Check and double check all the polarity and pin installations of the electrolytic capacitors, diodes and transistors.?? As far as ICs, make sure you have them positioned properly.???? When the manual says to verify PIN 1, you verify PIN 1. My only fault was that I installed an IC backwards.?? I looked at that thing daily and did not see that the large 'dimple' on the top and to one side of the IC was NOT the side with pin1 and the notch.???? It wasn't a costly mistake, but I lost about 4 weeks waiting for it to come back from Elecraft.????? FWIW ... I wasn't the only person who missed that, so I didn't feel so bad :) Make sure you have the right solder, and a GOOD temperature controlled soldering station.? I got a Hakko FX888 from Amazon for $97.00. Have a VERY GOOD digital meter that can measure capacitance, resistance, DC voltage, etc.??? Comes in handy when verifying parts you can see easily, but later on during the alignment steps. I had a good time putting it together.? I'm ready to build another one just because it was enjoyable, frustrating at times, but mostly enjoyable.??? The support from Elecraft is amazing, an email at 8 pm ET, would get a reply by 10 pm only because I don't think Don sleeps! Don't hesitate to send emails if you have a question, as the book says, they will not let you fail.???? Make sure you make the changes in the main manual as listed in the errata, definitely saves you time, and errors.????? I'd also download the K2 Manual Appendices from the website, and print out the board component location diagrams.?? Once you start placing components, you may not be able to see exactly where that final part goes, but the diagrams help, and taping them up over your bench keeps you from having to flip back and forth from your installation step to the diagram.?? I even printed out the inventory parts list from that file, made the changes from the errata, and used that to identify parts if needed to keep me from flipping back and forth. Finally, the Elecraft website has a lot of good tips under its "Builder Resources" page.? I will let you know that many of the K2 mods there are already incorporated in the new kits, so you can read about them, but you don't have to do them.?? You can verify if you need anything yourself. Enjoy, there is nothing that gives me greater satisfaction to turn on my K2/100 and say .. "I built that .. and it works !!!"

But if you are downloading the digest to your computer and not wanting it on your smartphone or other web based application, then read on. If you have an email client on your computer, IMHO subscribing to the digest is a cumbersome way to view the Elecraft email list. Subscribe to individual emails. Create a folder in your email client for the Elecraft emails. Set a filter to place all incoming emails with [Elecraft] into that folder. Presto -- you have your own digest on your computer. If you do not want to see the OT posts, simply create a filter to place anything with "OT" into into your trash. Mozilla Thunderbird works nicely and is free - multiplatform as well. 73, Don W3FPR On 6/16/2018 11:20 AM, Thomas Schaefer wrote: > While inevitably I will hear from people that I should just click hit the DELETE key, I get the digest form of this email list.

I changed over to non-digest. I use a Mac so I already have all radio list email go into a Smart Folder. I created a rule to automatically delete any email that has OT in the subject (ironically, this one). Hopefully we can ask people to give some serious thought to what they write and if they must post something off-topic, to include OT in the subject. Again, just a polite request?I?m not telling people what to post. I believe that takes care of this one so thank you all for your consideration and the bandwidth. We can now go back to discussing how FT8 cannot be used at Field Day (with my K3 to make it tangentially on topic) or how my P3 makes a better pan adapter than back in the day when I used an Kenwood SM-220 (and the resulting 30 post thread about how good the Kenwood TS-820 line was).

From dfmaase at aol.com Sat Jun 16 12:16:34 2018 From: dfmaase at aol.com (Dan Maase) Date: Sat, 16 Jun 2018 12:16:34 -0400 Subject: [Elecraft] K3 SSB + CW Power Overshoot Message-ID: <16409624b1f-c8a-18318@webjas-vab243.srv.aolmail.net> The K3 SSB + CW Power Overshoot behavior has been passed up the Elecraft Tech/Engineering chain.? I expect it may take them some time to get to it, so in the meantime it would be useful for those interested to conduct the test below to determine if the behavior is unique to my K3 or more wide spread.? ? My primary concern is operating with the K3 driving an amplifier (KPA 500 in my case).? It is often the case that the overshoot is so high that the KPA faults on the first key press when power is set for 500 watts and in SSB +CW mode. __________________________________________________________________________________ ? Following is a repeatable test that exhibits the overshoot and power adjust instability problem we have been discussing. ? Setup: 1,? Output terminated in dummy load (ANT 1) 2.? Config: CW WGHT -- [1]? SSB +CW 3.? S Meter Peak -- ON 4.? Meter Mode -- SWR/RF (to observe output power) 5.? Set Power 50 watts (initial setting) 6.? Select any band ? Operation: 1.? Select CW mode; VOX on ? Press key and hold. ? ? Note that power ramps up to the set 50 watt value ? ? Adjust power up or down; note that the power change is smooth with no jumps or overshoots ? ? Press key on/off/on .... -- power always returns to set value ? ? Release key and set power to 50 watts ? 2.? Change to SSB mode (upper or lower) ? ? ??Press key and hold while observing watt meter -- note that power overshoots the 50 watt level and then? ? ??? ??? ?drops to 50?watts. ? ? Adjust power up.? Note that the power jumps high then returns to set value.? ? ? Adjust power down.? Note that the power jumps high, than returns to set value. ? ? (note that whether the power is adjusted higher or lower, the output power jumps higher, then ? ??? ??? ??? ?reduces to the?set value). ? ? Also note that the power supply current jumps (overshoots high) coincident with each power adjustment. ? ? Release key, then press again and hold. Note that the power does not overshoot the set value.? Release and ? ??hold any number of times and power continues to be stable at set value. ? Changing now to CW mode with VOX and power is stable. Changing back to SSB +CW and power is unstable and with overshoot with first key press. ? This phenomenon occurs in both HP and LP modes. This phenomenon is apparent when the K3 is initially turned on from a cold start, but gets progressively more pronounced after about 10 minutes of on time in quiescent state (no RF out).? PA Temp at this time is 25C.? As requested, fan is set to level 1. ? Discussion: It is my understanding from old Reflector mail posts that the SSB +CW mode is implemented such that when key is pressed, the K3 changes dynamically from SSB to CW mode.? It appears that the CW ALC function is not in play until some time delay after key press, at which time the CW output settles at the set power level.? This time delay would appear to be at the root of the problem.? When the power is adjusted, it would appear the ALC loop opens up and then re-engages when adjustment stops. ? The fact that the phenomenon changes in magnitude as the K3 warms up, may simply be a function of linear stages within the ALC loop changing gain with temperature. ? The above test sequence is easy to apply and as such would be very curious to see if the phenomenon occurs on any of the Elecraft bench test K3's. ______________________________________________________________________________________ ?

What is SSB +CW?? ? 73, Jim K9YC? _________________________? Jim: SSB +CW is a mode/configuration whereby one can send CW when in the SSB mode. ?The CW frequency is offset from the SSB carrier frequency by the value of the selected CW side tone. ?Purpose: ?enables means to reply to a SSB communication with CW in poor band conditions. ??

Taylor, WB6UUT) Date: Sat, 16 Jun 2018 16:31:13 -0700 Subject: [Elecraft] Sorting mail automatically Message-ID: <1bb46059-7ff5-8823-35cc-4d359db2ec96@ColdRocksHotBrooms.com> I've mentioned this before, but it bears repeating. There is this awesome program called POPFile. You can get it here: This is an automatic mail classifier based on "Naive Bayesian Filtering" but you don't need to worry about that. Like all of us, I have some specific interests in what shows up on the list. I'd like something to sort them so that I don't have to. Let's say I'd like list mail sorted into the following: KX3 Portable Digital Modes Antennas Other I'd grab a copy of POPfile and set it up on my computer (Windows, Mac, whatever). I'd set up "buckets" for each topic in POPfile. Then I'd set up folders in my mail client, one for each topic. The POPfile website tells how to set up your mail client to read headers added by POPfile and create rules to move the mail. ... then you have POPfile check mail. First time, all of the mail will end up in the same place. You go through and read some messages and "classify" them -- there is a link that lets you tell POPfile which "bucket" or "folder" the message goes in. From this point forward, you scan the folders and reclassify only the messages that ended in the wrong place. After classifying maybe a dozen messages, POPfile will get it right more than 80% of the time. It gets better fast. If you're bothered by how much off-topic or uninteresting mail shows up on the list, this is your answer. I gave a more complex example. You could just sort the mail into "cool" and "boring" if you like. POPfile is free. 73 -- Lynn From dennisashworth49 at gmail.com Sat Jun 16 19:39:59 2018 From: dennisashworth49 at gmail.com (Dennis Ashworth) Date: Sat, 16 Jun 2018 19:39:59 -0400 Subject: [Elecraft] Sorting mail automatically In-Reply-To: <1bb46059-7ff5-8823-35cc-4d359db2ec96@ColdRocksHotBrooms.com> References: <1bb46059-7ff5-8823-35cc-4d359db2ec96@ColdRocksHotBrooms.com> Message-ID: <207B2ACB-DBE8-4950-859F-FFE8391A7DCB@gmail.com> I have no problem filtering mail, but why don?t we (as subscribers) respect the posting guidelines and keep ON topic?

Message-ID: My current station is a K3s, KPA500 and a remote MFJ 944BRT auto tuner. The remote auto tuner is being replaced with a local KAT500 and I am a bit confused on the workflow described in the manual. The K3s does not contain the built in auto tuner and the three boxes will be connected per Figure 1. Cabling Diagram: Elecraft K3, KPA500 and KAT500 Using E850463 Aux Interface Cables on page 5 of the KAT500 manual. The question(s) are: 1. With the KAT500 in the ?Auto? mode and the K3s ?Tune? power level set for 10 watts and the KPA500 on and in the Operate mode will the KAT500 automatically drop (not key) the KPA500 offline and perform an autotune, when the K3s ?Tune? button is pressed and the SWR exceeds the preset level? 2. With the KAT500 in the ?Auto? mode and the K3s ?Tune? power level set for 10 watts and the KPA500 ?ON" and in the ?OPERATE" mode will the KAT500 leave the KPA500 online and drive the KPA500 to whatever output 10 watts drive delivers when the K3s ?Tune? button is pressed if the SWR DOES NOT exceed the preset level? I assume that this will be the condition when returning to a previously tuned band/frequency. 3. If either 1 or 2 or both are not true is the procedure to always manually place the KPA500 in the ?Standby? mode until all KAT500 tuning operations have been completed.

Vacuum variables aren?t hard to find, but the $200 and up price tag is offputting. I have seen a couple of AVCs on E-bay that looked pretty ratty; and the commercial types for sale new look like low-power trimmers. Anyone know of a source -- or even have any they?d sell? Specifically I would like a range of 6 to 120 pf or more, butterfly or split stator, with plate spacing sufficient to take a kilovolt of RF. And ideally with reduction gear tuning though that?s optional. Thanks for any info anyone can provide . . .

Message-ID: FWIW, I have had a KAT500 for a few years now. I never use the KAT500's Auto setting. Once the KAT500's memories are set up, the Manual setting does everything I need. First, with the KPA500 in Standby (or turned off), for every band/antenna combination I use, I trained the KAT500 across the band. I did this by tuning to a frequency near the bottom of the band, tapping the KAT500's Tune button and then pressing the K3's Tune button (a long press, since Tune is a "hold" function) and left the K3's Tune signal running until the KAT500 found the best match, then turned the K3's Tune back off. Tune up 20 kHz and press the Tune buttons first on the KAT500 and then on the K3 until the KAT500 finds a match. Keep doing this until the band is covered. Repeat for all other band/antenna combinations. On 10 meters, you only have to do this every 100 kHz instead of every 20 kHz, and on 6m, only every 200 kHz. On 160m, the settings to be remembered are every 10 kHz. Once this set-and-forget once-only training step was completed, I just leave the KAT500 in Manual mode all the time. As I tune the K3 around, the KAT500 reads the frequency from the K3 and automatically selects the antenna for that band and the settings I trained it with for that frequency and antenna. You can hear the relays in the KAT500 click as you move from one band to another, or from one frequency memory segment to another one as the remembered tuner settings change. As long as the impedance presented by your antenna's feedline to the tuner does not change from what it was when you trained the tuner, the remembered memory settings will work fine. Sometimes, e.g. when it rains or snows, the SWR with the original setting starts to get higher. Perhaps this is the kind of situation where the Auto setting would touch the settings up automatically, but I heartily dislike having the tuner suddenly spring into action mid-QSO. Instead, I wait for a quiet moment, put the KPA500 in standby, put the KAT500 in Tune mode and use the K3's Tune button again in order to find the best match for the current conditions. As soon as the KAT500 finds a match, I put the KPA500 back into operate and carry on. Usually when this happens, the abnormal tuner settings are only needed for a few hours, and as the humidity returns to normal I redo the training procedure once more to bring the KAT500's memory for that particular frequency/antenna combination back to normal. 73, Rich VE3KI From pincon at erols.com Sat Jun 16 20:58:13 2018 From: pincon at erols.com (Charlie T) Date: Sat, 16 Jun 2018 20:58:13 -0400 Subject: [Elecraft] OT: Color code memory aid ...

In-Reply-To: References: Message-ID: Thanks Fred. Your document mirrors what I have heard, in various versions, from several local K3/KPA/KAT owners. Your logic for leaving the tuner in the ?Manual? mode makes some sense but I wonder why the software command structure does not automatically place the K3/K3s in the ?Tune?mode when the ?Tune? button on the KAT500 is pressed. Having to press two ?Tune? buttons in sequence seems a bit crude for an otherwise elegantly integrated system. But! Thank you for your input Fred. It is clear. Some input from Wayne as to his views on the implementation of the K3/KPA/KAT tuning system would also be welcomed. The reason I just ordered the KAT500 was because of a recent catastrophic failure of both VRF2933s in my KPA500, While the failure was covered quickly and completely by Elecraft?s near perfect warranty I want to do whatever I can to insure it doesn?t happen again. My goal is to achieve as much automated protection as possible.

With the KAT500 in the ?Auto? mode and the K3s ?Tune? power level set for 10 watts and the KPA500 ?ON" and in the ?OPERATE" mode will the KAT500 leave the KPA500 online and drive the KPA500 to whatever output 10 watts drive delivers when the K3s ?Tune? button is pressed if the SWR DOES NOT exceed the preset level?

Once the KAT500's memories are set up, the Manual setting does everything I need. First, with the KPA500 in Standby (or turned off), for every band/antenna combination I use, I trained the KAT500 across the band. I did this by tuning to a frequency near the bottom of the band, tapping the KAT500's Tune button and then pressing the K3's Tune button (a long press, since Tune is a "hold" function) and left the K3's Tune signal running until the KAT500 found the best match, then turned the K3's Tune back off. Tune up 20 kHz and press the Tune buttons first on the KAT500 and then on the K3 until the KAT500 finds a match. Keep doing this until the band is covered. Repeat for all other band/antenna combinations. On 10 meters, you only have to do this every 100 kHz instead of every 20 kHz, and on 6m, only every 200 kHz. On 160m, the settings to be remembered are every 10 kHz. Once this set-and-forget once-only training step was completed, I just leave the KAT500 in Manual mode all the time. As I tune the K3 around, the KAT500 reads the frequency from the K3 and automatically selects the antenna for that band and the settings I trained it with for that frequency and antenna. You can hear the relays in the KAT500 click as you move from one band to another, or from one frequency memory segment to another one as the remembered tuner settings change. As long as the impedance presented by your antenna's feedline to the tuner does not change from what it was when you trained the tuner, the remembered memory settings will work fine. Sometimes, e.g. when it rains or snows, the SWR with the original setting starts to get higher. Perhaps this is the kind of situation where the Auto setting would touch the settings up automatically, but I heartily dislike having the tuner suddenly spring into action mid-QSO. Instead, I wait for a quiet moment, put the KPA500 in standby, put the KAT500 in Tune mode and use the K3's Tune button again in order to find the best match for the current conditions. As soon as the KAT500 finds a match, I put the KPA500 back into operate and carry on. Usually when this happens, the abnormal tuner settings are only needed for a few hours, and as the humidity returns to normal I redo the training procedure once more to bring the KAT500's memory for that particular frequency/antenna combination back to normal. 73, Rich VE3KI From wunder at wunderwood.org Sat Jun 16 22:33:43 2018 From: wunder at wunderwood.org (Walter Underwood) Date: Sat, 16 Jun 2018 19:33:43 -0700 Subject: [Elecraft] OT - Source for Air Variable Capacitors In-Reply-To: <78545681-376C-4696-B4D5-5EDEBD741B4B@law.du.edu> References: <78545681-376C-4696-B4D5-5EDEBD741B4B@law.du.edu> Message-ID: <952D32D2-A6A5-4983-98D6-DFAE95C4F68F@wunderwood.org> MFJ sells butterfly capacitors.

I have backed off the contacts and verified that the little wires aren't shorted, and I seem to have narrowed down the problem to how snugly it is attached to the KX2. If I tighten then thumb screws finger-snug, it starts sending dits as if it's shorted. Backing off the thumb screws a bit seems to help with the issue. Obviously there's a short somewhere, but I'm not sure where to check. I'm not sure why the tightness of the thumb screws on the KXPD2 would cause a short. Does anyone have any suggestions on what to try next? I'm leaving for a camping trip tomorrow, and I'm taking the KX2 with me. I had hoped to use the KXPD2 paddle, but it looks like I may be packing one of my other paddles for this trip just in case. Any suggestions will be appreciated!

Definitely the beam at 80 feet helps but still it's great to be working JA and others on 21 and 28 MHz with just the 10 watts from my HS QTH. Since building the K2 it's been one of the first times I've been able to put it through its paces and it is a lot of fun. A quirk I've noticed, easy to work around, but I'm curious if its just mine. After a band change the first dit, or two, is not at full power. There seems to be an initial ramp up after which all is good and I don't see any fluctuation in power. Supply is 13.5 volts when producing full power, about 13.9 with just the receiver running. Full power current on 28Mhz is showing on the display as 2.66A. I can see the ramp up on the bar graph, it shows one bar for the first 3-4 dots then ramps up to all 10 bars. I have confirmed the same with an external power meter. Anything I can do about this?

To prevent overshoot, it starts out low and ramps up quickly to the requested power. It must sense the actual power output and adjust the drive accordingly, and that takes one or two dit times to happen. 73, Don W3FPR On 6/17/2018 2:43 AM, Martin Sole wrote: > A quirk I've noticed, easy to work around, but I'm curious if its just > mine.

This could leave the screw heads slightly exposed. You can contact support to obtain a replacement. As a temporary workaround, place a bit of adhesive label material on the back, over the screws. 73, Wayne N6KR ---- http://www.elecraft.com > On Jun 16, 2018, at 11:37 PM, Michael Jarvis wrote: > > Hello, > > I'm a fairly new owner of a KX2 with a KXPD2 paddle, and I just noticed this evening that something is causing the paddle to get "stuck" sending dots.

If you are using SSB, then you may have some TX EQ cranked in and the power varying with the audio tone. DATA A automatically sets compression to zero and equalization flat. Be certain to open up the bandwidth to maximum. DATA A defaults to a narrow bandwidth. 73, Don W3FPR On 6/17/2018 1:02 PM, MaverickNH wrote: > Yep - got that set with PC at ~30%, WSJT-X slider at ~60% and MIC (Line Gain) > at 18 so 4 bars solid and 5th just flickers.

I went ahead and took delivery of the amp Friday and hooked it up this morning. I have all of the equipment installed in a rack just to the right of my operating desk (updated pictures on qrz.com) within easy reach. I went ahead and set the fan to position 2 and started calling cq on 10m RTTY at 1500 watts output (no answers unfortunately).? I kept this up for 15 minutes or so.? With the fan set to 2 the temp approached 60 degrees.? I'm sure the amp will jump to fan 3 when I've operated RTTY for more than 15 minutes but I'm betting it doesn't stay at the setting for very long. I need to set the fan back to setting 0 and do some testing to see when the fans start and at what temperature.? I need to do this in all modes.? I started with RTTY as that's the most demanding mode that I operate. The fan noise at 2 is quite acceptable with no head phones on. The power supply fan is very acceptable.? It sounds like a fan on a computer to me.? It doesn't have a high pitch wine to it. Bottom line I'm glad I took delivery.? I still need to read the manual and setup the ATU but so far so good.? It's great having 1500 watts available if needed. I plan on using the two Elecraft amps for SO2R.? Hopefully the setup will get a good work out during IARU next month.

I removed the solder from the pins, flush-cut the pins on the solder-side, and solder-sucked a coupke more times. I then gently rocked the part side to side on the component side of the board until it broke free. > On Jun 17, 2018, at 11:18 AM, Don Wilhelm wrote: > > Mark, > > The only way I know of to do it reliably is to replace the inductor. > I suspect you stripped the threads on the inside of the inductor core and not the slug.

If so, just press and hold the ALT button unit the REV is no longer displayed above the DATA label on the display. As to SPLIT, that is to assure your transmitted tones are between ~1500 Hz and ~1999 Hz thus any distortion products are outside of the transmit SSB filter and thus attenuated by the filter.?? Thus if you are working a stations which is at 450 Hz on the waterfall, the software will shift the VFO such that the correct tone is transmitted to the receiving station.?? All of this is done? by the software and the radio under CAT control. With the WSJT-X setup, F2 menu, under the GENERAL tab and in the Behavior box,? the VHF/UHF box is not checked. I did tests with my K3S set at 50 watts.? Then transmitted data at 300 Hz, 1200 Hz, 1800 Hz and 2100 Hz.? The power output varied between 50 and 55 watts as read on an external power meter, and the K3S power bargraph always indicated 50 watts. If your settings and tones from WSJT-X are keeping the ALC bargarph between 4 and 5 bars then the power output from the K3S should be the value as set by the PWR control on the radio. Remember, unlike other radios, the K3S ALC bargraph shows audio level for the first 4? bars.? The actual ALC does not begin until after the 5th bar.?? Once set, do not change the PWR slider on the right side of the WSJT-X panel.?? The actual transmit power is to be controlled only by the PWR control on the radio. In my analysis, if your K3S output meter shows constant power and your KPA500 LED power indication is constant, then the issue lies with the P3TX MON. 73 Bob, K4TAX On 6/17/2018 7:08 PM, MaverickNH wrote: > Hi Don, I checked and my K3S is set in DATA A mode.

It can be off-list as this as probably been "hashed > over" before (I just didn't pay attention). I'll stick to the list. First, temperature stability is a MAJOR issue on the higher bands, especially 6M, for early serial number KX3s. As an introduction, skim this page. http://www.bigskyspaces.com/w7gj/KX3HeatSinks.htm After Lance's KX3 was built and after he made Elecraft aware of the issues, the main board was redesigned to eliminate the problem he highlighted, and the heat sink was beefed up. Elecraft also built into the firmware support for a temperature compensation procedure to be done by users. The good news is that, IF the TC run is done, a current production KX3 with these running production changes works very well for MSK and FT8 on 6M. The bad news is that while the main board can be replaced, it is VERY expensive. Better to sell your older KX3 and buy a new one. :) 73, Jim K9YC From nw8l at whitemesa.com Mon Jun 18 19:37:46 2018 From: nw8l at whitemesa.com (Robert Cunnings) Date: Mon, 18 Jun 2018 17:37:46 -0600 (MDT) Subject: [Elecraft] OT - Source for Air Variable Capacitors In-Reply-To: <7D5B07F7-D8AF-44C2-9EDD-61EAD45C615B@wunderwood.org> References: <90810604.1185391.1529323979618.ref@mail.yahoo.com> <90810604.1185391.1529323979618@mail.yahoo.com> <7D5B07F7-D8AF-44C2-9EDD-61EAD45C615B@wunderwood.org> Message-ID: Yes, the stator-stator 15-120pF range applies to the mag loop butterfly configuration. stator-stator is equivalent to 2 stator-rotor capacitances (20-250pF) in series, approximately.

Use the computer output controls to establish that level with the KX3 Mic Gain set to mid-range. You will want to use the headphone output of the KX3 rather than the IQ output.

It also functions much as a Piglet when using Ser2Net to give a virtual serial port accessed just like Piglet. This keeps my home tidy and is friendly towards my XYL. The Bluetooth solution would be small and elegant for ACC1 - and portable for travel. Further research has now shown the IRXON Bluetooth Serial Adaptor BT578 adapter , which is moderately priced. My idea was if the HC05 can interface directly then it would give very low cost wire free solution.

Into a dummy load I was getting high SWR numbers. I have been so busy at work that I haven't had the time to find the fault, but what does seem to work for me is not to tighten the case bolts too tightly. Looser is better, but not so loose that the rear legs are flopping about. When I relieve the tightness on these bolts, SWR values always settle around 1.0-1.2 depending on the antenna. Too tight and SWR jumps up to between 3-15. This sounds to me like a bad ground somewhere. Just haven't had the time to investigate. Another time that I had the types of SWR you are observing (25+, even 45+ for me), a few years ago, I had to send the KX3 back to Elecraft and they repaired something. I am not at home now so I can't recall specifically what they repaired. The prevailing theory of the issue was perhaps a static discharge from the antenna during the winter months when I connected the KX3 one day. This was my first experience with static discharge in the antenna system, assuming that was the problem that fried one of the components in the KX3. Again, can't recall which component (actually a surface mount chip on one of the larger components), but it needed to be replaced. regards, Brian VE3IBW On Mon, Jun 18, 2018 at 8:42 PM Bill Frantz wrote: > Thanks for reminding me to look at dumb things. > > Yes, the BNC was pugged into the tuner board.

Pin 8 is the "Power On" pin. Pulsing that pin low will cause a KPA500 or KPA1500 amplifier to power up. Powering up the K3 could cause such a pulse if you have the wrong cable connected between things. Pin 8 of the KPA1500 and KPA500 could also be connected in parallel to each other. Solution: use an Elecraft AUX cable, not a 15-pin cable or VGA monitor cable, between the Y-BOX, the KAT500, and the KPA1500. This cable has no connection on the power on pin. The recommended way to correctly connect these devices together would be: K3 ACC Port -> 15 pin M/M cable -> Y-BOX input Y-BOX v1.3 Output 1 -> Elecraft M/F AUX cable -> KAT500 -> 15 pin M/F cable (or another AUX cable) -> KPA500 Y-BOX v1.3 Output 2 -> Elecraft M/F AUX cable -> KPA1500 Y-BOX v1.3 Outputs 3/4 -> Other devices (Band Decoder, MK2R+, RemoteRig etc.) Some Elecraft AUX cables were modified to short Pin 11 (DIGOUT1) to Pin 8 to allow for remote power on. If you bought the cable second-hand, it may have been modified to do that. FYI, for Y-BOX v2.1 (upgrades available), only one Elecraft AUX cable would be needed to connect all three devices (KAT500, KPA500, KPA1500), because the new Y-BOX v2.1 has one dedicated "AMP AUX" port, which by default has no connection in pins 1, 4, 6, 7, and 8, same as the AUX cable). So it can be wired like this: K3 ACC Port -> 15 pin MM cable -> Y-BOX input Y-BOX v2.1 AMP AUX Output -> 15 pin M/F cable -> KAT500 -> 15 pin M/F cable -> KPA500 Y-BOX v2.1 Output 2 -> Elecraft M/F AUX cable -> KPA1500 Y-BOX v2.1 Outputs 3/4 -> Other devices (Band Decoder, MK2R+, RemoteRig etc.) 73, Bob, N6TV https://bit.ly/Y-BOX From ebasilier at cox.net Tue Jun 19 17:39:07 2018 From: ebasilier at cox.net (Erik Basilier) Date: Tue, 19 Jun 2018 14:39:07 -0700 Subject: [Elecraft] K3 receive audio phenomenon Message-ID: <01b601d40815$f3d11b90$db7352b0$@cox.net> I was transmitting wspr on 40 at 100 mW from a WSPRLite tx, and monitoring on an antennaless K3 in SSB mode (just listening in SP3, not trying to decode). (Background: I have for a while been fascinated with how room accoustics will sometimes, with a given head position, make the tone in cw reception almost disappear). Watching the WSPR signal on the P3 at minimum span, I could see two sideband peaks well separated from the carrier. Tuning slowly I noticed something similar to the cw/room accoustics phenomenon: At a certain tuning point the whistle from the speaker got very quiet. Moving my head around I concluded that this was probably not room accoustics but some kind of characteristic of the wspr modulation. Be that as it may, then came a big surprise, and here is my main issue for the group: Suddenly there was a loud click followed by complete silence, which lasted a second or so. It was like someone had ripped the speaker cable out of the radio. The normal sound then came back, but several seconds later the click and silence came again. This seemed to cycle forever. The picture on the P3 remained steady, so the wspr tx did not interrupt its operation, and the K3 front end kept operating normally. I then tuned around, changed the rx to cw, etc, and the phenomenon went away. Normally I would take time to study further before bothering the group, since many things could cause a break in rx audio, but I have not been able to repeat it. One thought that came to mind was that somehow the K3 dsp got saturated and hickuped, but the received signal was quite weak on a quiet band, only about 20 or 30 dB above noise, and hardware agc should prevent that anyway. While I am waiting for something similar to happen in the future, I am just asking the group if anyone has had a similar experience.

I used the KPA1500 meter to measure output, and the K3 power setting for input.? Results on the two bands were similar, though 15 required much more drive. On 40, the maximum gain occurred at about 800 W out, 17.2 dB.? At 1 kW, it was 16.9 dB, and at 1.5 kW it was 15.7 dB.? However, at 1.45 kW the gain was 16.2 dB, so there was a lot of compression in that last 55 W. The gain compression at 1.5 kW vs 1 kW is 1.2 dB, but only 0.7 dB at 1.45 kW.? Overall, I'm told this compression is typical of the KPA1500, and probably doesn't indicate excessive IMD, at least compared to other solid-state amplifiers. It's probably a good idea to be very careful not to overdrive it on SSB, though. The gain drops off at low power, to 16.0 dB at 200 W.? This is consistent with the BLF188 data sheet. However, the data sheet shows the gain almost perfectly flat to over 1 kW per device. They show maximum gain, in fact, at about 1 kW per device, which means gain ought to be a bit HIGHER at 1.5 kW than 1 kW for two devices. Since there are two of them in the KPA1500, the compression at 1.5 kW is a bit surprising. (That's about what one would expect from ONE device at 1.5 kW.) Yes, the data sheet curves are for a specific test circuit at 108 MHz, but it's still surprising. On the other hand, anyone who has designed electronics knows to take the published data sheets skeptically.? Elecraft has, no doubt, tested lots of them, and knows their REAL characteristics. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From john at kn5l.net Tue Jun 19 18:25:08 2018 From: john at kn5l.net (John Oppenheimer) Date: Tue, 19 Jun 2018 17:25:08 -0500 Subject: [Elecraft] KPA1500 Linearity In-Reply-To: <1a82ab84-1b39-ce29-147e-e7b7a5b44edb@sdellington.us> References: <1a82ab84-1b39-ce29-147e-e7b7a5b44edb@sdellington.us> Message-ID: <4aead6f9-ff90-a63b-ddc3-868455c25478@kn5l.net> Hi Scott, I wonder how the linearity of the two power meters was evaluated?

Typically wattmeters use diodes in their detectors, and the response will vary by frequency and by the power level. I would trust only something that has been calibrated to NIST traceable standards. The Telepost LP-100 is one example (and those are used on many Elecraft test benches). While 10% is an OK deviation for amateur purposes, two wattmeters each with 10% accuracy can lead to a 20% error in the final measurements. It is too easy to jump to conclusions by not considering the potential errors in measurement accuracy. If you want 5% accuracy in your conclusions, your measurement tools should be accurate to 0.5% - a far stretch for wattmeters as we know them. 73, Don W3FPR On 6/19/2018 6:25 PM, John Oppenheimer wrote: > Hi Scott, > > I wonder how the linearity of the two power meters was evaluated? > > Some years ago I checked the K3 and KX3 power meter against two other > meters.

Only one is actually 50 ohms but others are as low as 45 ohms and as high as 58 ohms, while one actually measures 50.5 ohms.?? If one is trying to measure power then both voltage and current should be measured with a known load and then do the math.? If you are using an antenna, it most likely is somewhat reactive.? This throws another curve into the ballpark in terms of power measurement. 73 Bob, K4TAX On 6/19/2018 7:15 PM, Fred Jensen wrote: > Most, if not all analog measurement devices are spec'd at % of full > scale which can lead to high absolute variances if the levels being > measured are significantly below full scale.?

I worked with Gary at Elecraft support who was a big help in shooting the problem. Your message was also an important clue, and maybe knowing about my problem will help you with yours. I ended up taking out the 2M board and the ATU board and the KX3 worked. I added in the ATU board and it still worked. When I put the 2M board in, the problem became intermittent. (GRRRRR!) I finally got it so I could poke at one corner of the 2M board and make the problem appear and disappear. It appears that my problem was being caused by having the antenna coax for the 2M SMA connector touch a toroid on the ATU board. The 2M board installation instructions warn about allowing that to happen. Just moving it caused the problem to appear and disappear. I'm hoping I have cured the problem, but time will tell. 73 Bill AE6JV On 6/19/18 at 9:30 AM, brian.waterworth at gmail.com (Brian Waterworth) wrote: >Hi Bill, > >I too suffered from issues as you are now with my KX3.

For those of > you who have such laptops, what is the current demand, and what is the > most common plug which such a supply would need to have? Several observations. First, that 14V supply is NOT quiet when providing enough current for transmit. Second, some laptop power supplies are quieter than others. For more than ten years, I've used nothing but Thinkpads, and I've always choked their cables. As a result, I don't hear noise. Third, the charge regulators for batteries inside laptops are at least somewhat dependent on the power supply feeding them. Failing to take this dependence into account could eventually result in premature end to the life of the battery. As to universality -- my older vintage Thinkpads came with a 16VDC supply with a rating in range of 3-4.5A, depending on model. Newer ones use a 20VDC supply in the same current range. There is little standardization of power plugs -- Lenovo's latest is rectangular in shape! Someone in this thread said he uses a DC-DC converter. The circuitry that does this has the same likelihood to create noise as any other switch mode power supply. I've standardized on Power Poles for all the DC in my home and shack. For most of the equipment, including laptops, I break the DC cables and add mating Power Poles to both the end coming from the PSU and the end going to the device. I've even done this for several laptop power supplies. This allows me to get around the non-standard connector issue, and also to use power supplies for older laptops that no longer work for other things. I never throw stuff like this away. I'm using vintage linear wall warts to replace noisy SMPS wall warts provided with new equipment. I'm using two old laptop power supplies to float-charge the batteries that run my shack, using a suitable charge regulator. Genasun makes several MPPT charge regulators for small solar systems, each designed for different battery chemistries and different panel voltage and current ratings. These Genasun regulators are pretty RF-quiet. If used VERY close to antennas a choke will kill what little noise you might hear. 73, Jim K9YC From wes_n7ws at triconet.org Wed Jun 20 13:36:34 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Wed, 20 Jun 2018 10:36:34 -0700 Subject: [Elecraft] KPA1500 Linearity In-Reply-To: References: <1a82ab84-1b39-ce29-147e-e7b7a5b44edb@sdellington.us> <4aead6f9-ff90-a63b-ddc3-868455c25478@kn5l.net> Message-ID: <8c72d186-dce3-7516-d598-15e1595c11d3@triconet.org> To make these kinds of measurements with amateur equipment and accuracy, I suggest acquiring some directional couplers and/or high power attenuators.? A spare K3 or a decent SDR receiver then makes an excellent "power meter" with significant dynamic range.? Gain measurements are really ratio measurements and seldom, if ever, require NIST traceability.? The ancillary hardware can be characterized by substitution. One further point: Although it's possible that two 10% accuracy power meters will have 20% uncertainty, it's highly improbable. In industry, all uncertainties: mismatch errors due to reflection coefficients of sources and power sensors, linearity errors, noise, temperature effects, etc are combined into one uncertainty by RSSing the individual errors.? You never add all the worse cases to get the answer. Wes? N7WS On 6/19/2018 3:42 PM, Don Wilhelm wrote: > John, > > You are exactly right for bring that factor to attention.

Message-ID: Here's the story. It's an odd one. Hope you don't mind a little rambling. The Barred Owl Radio Club W4OWL got together in Floyd, VA last year for a great Field Day. All the rigs were Elecraft Kx3 running QRP battery and it was an fantastic event for a small group of friends. Not long after Field Day I came across a fellow that does watercolor drawings for business. Out of the blue I asked him if I could send him some pictures of our event and get his interpretation of it. He was all over it! For months we went back and forth and, in the end, I not only got a wonderful watercolor original and some prints for the rest of the team but he added an additional drawing which actually seems a bit more Elecraft-focused... so not so OT.

Before I had aluminum in the air, I worked 6M with a pair of 80/40 fan dipoles. They were up 100 ft and fed with very good RG11. Running 100W, I managed to make several double-hop QSOs both to the east coast and to KH6. When I lived in Chicago, my 6M antenna was a pair of stacked horizontal loops up about 40 ft. I remember working a guy on Long Island with his antenna in the basement! 73, Jim K9YC From bobdehaney at gmx.net Thu Jun 21 02:43:51 2018 From: bobdehaney at gmx.net (Bob DeHaney) Date: Thu, 21 Jun 2018 08:43:51 +0200 Subject: [Elecraft] Tx Mon Message-ID: <000701d4092b$37a17980$a6e46c80$@gmx.net> I have a P3 with the TX Mon option.

(latest firmware) Maybe I am missing something... Example: When I select "data" with the mode switch and have DATA A selected the bandwidth is approx. 700 Hz. The bandwidth indicator gives "max. bandwidth" (all the bars). Given the fact that e.g. WSJT uses wide band audio I change the bandwidth settings to maximum, being 4 kHz. (Lo = 0.05, High = 4.05) The bandwidth indicator still gives "max. bandwidth" (no change to previous indication) Now I switch to AFSK A : I get the dual band pass filter for RTTY, as previously selected. So far, so good. However, I almost do not hear anything. Only when I turn "HI" a little bit back and forth I do get the narrow filter response in audio. As a next step I switch back to DATA A. Once again I get the indication of a large bandwidth in the display, however what I hear is quite narrow. Lo is set to 1.15 and High to 1.85. The bandwidth indicator still gives "max. bandwidth" I have to adjust shift/width to get the original/wanted 4 kc again. So I always see the wanted bandwidth in the display, but never hear the corresponding audio bandwidth right away when switching between DATA A and AFSK A. I get the impression that the bandwidth at DATA A has a fixed setting and is not stored like in SSB/CW. The behaviour at AFSK A is not clear to me. (The same happens when I switch to PSK D. No audio as well.) This could all be my error (if so, what am I doing wrong), dedicated design (if so, why?) or a bug. Can someone please tell me what I should do to get the correct behaviour and memory of bandwidth? Thanks! 73 Henk PA0C From jh3sif at sumaq.jp Thu Jun 21 05:41:00 2018 From: jh3sif at sumaq.jp (Keith Onishi) Date: Thu, 21 Jun 2018 18:41:00 +0900 Subject: [Elecraft] Data bandwidth behaviour K3s In-Reply-To: <008401d4093c$83456d40$89d047c0$@kpnplanet.nl> References: <008401d4093c$83456d40$89d047c0$@kpnplanet.nl> Message-ID: I guess that there is only ONE memory stack for entire DATA modes. So the latest filter setting is restored when any one of DATA mode is selected. If you have enabled multiple xtal filters for DATA mode, you can switch xtal filters by pushing XFIL and select band width accordingly. 73 de JH3SIF, Keith > 2018/06/21 17:47?Henk de Vries (hdv) ????: > > Hi guys, > > I experience a strange bandwidth behaviour when using DATA modes with my new > K3s.

This means that they can both read the status information from a Kenwood's COM port and act on it. This does not require the AUX cables which are specifically designed for the K3/K3S to provide the unique features they have when connected in that way. This would include the ability of the KAT500 to read the K3/K3S VFO frequency and pre-select tuning elements, band-tracking with the K3/K3S and the KPA500's ability to report its OPER/STBY status to the K3/K3S so it can switch between the 2 RF PWR settings it maintains on a per-band basis.

This means that they can both read the status information from a Kenwood's COM port and act on it." Now I'm getting confused. Based on earlier replies (list and off list) I understood that the KPA500 was the source of the single wire Aux bus and that both the KPA500 and KAT500 were listeners for the band discretes. How would the KAT500 receive frequency data from the Kenwood COM port? The KPA500 can be configured to do that, and mine is, but I see no way for the KAT500 to do that. There is no RS-232 transceiver port on the KAT500 and the RS-232 PC port appears to be usable only to exchange the KAT500 command set with a device that communicates using that command set. In my case the KAT500 PC port will be used to communicate with my station data logger. Perhaps its only of academic interest but I do like to have some understanding of the equipment I operate. 73, Andy k3wyc From jim at audiosystemsgroup.com Thu Jun 21 11:37:46 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 21 Jun 2018 08:37:46 -0700 Subject: [Elecraft] Tx Mon In-Reply-To: <6697DC10-4C55-4A77-B2FD-F79AB60D2572@me.com> References: <000701d4092b$37a17980$a6e46c80$@gmx.net> <6e04cbb2-f31f-59a8-ac33-5c38a9f80647@embarqmail.com> <6697DC10-4C55-4A77-B2FD-F79AB60D2572@me.com> Message-ID: On 6/21/2018 6:56 AM, Jack Brindle wrote: > Also remember that each box you insert into the line will cause impedance bumps and thus each will see slightly different loads.

The "AUXBUS" is a proprietary single wire communicaions interface that is used for communications between various units in the Elecraft gear - if for no other reason than to test for the presence of a particular device. The fact that the cable between the K3 and the KAT500/KPA500 is called the "AUX cable" - it is NOT the AUXBUS even though one of the wires is for the AUXBUS. That is quite different and separate from any RS-232 communications. There are no RS-232 signals in the AUX cable. 73, Don W3FPR On 6/21/2018 1:25 PM, ANDY DURBIN wrote: > It's clear that both the KPA500 and KAT500 must be RS-232 transmitters as well as RS-232 receivers.

It's important to understand how E-skip works. It's called "sporadic E" because it depends on sporadic activation of the layer for reasons that are not understood by me. Propagation from E-skip is often "spotlight" in nature, especially when more than one hop is involved. We can work "single hop" when the ionized cloud is roughly midway between us and the other station; for two or more hops, at least two ionized clouds must line up -- that is, ground to cloud one to ground to cloud two to ground. With double-hop Es, it's common to be able to work stations within a radius as small as 50 miles. And then one or both of clouds moves and a different radius is illuminated. Yesterday, for example, from here near San Francisco, stations 50-100 miles E of me were working China, and stations in TX and OK were working JA. I heard none of it. But at various times, a single skip cloud provided a path down to San Diego and into XE, another into AZ, S NM, and S TX. That was all before noon. Eventually I started seeing the SE US -- AL, FL, SC, GA, NC. Toward evening, we started seeing (and working New England and the upper Midwest (8-land). And so on. VT was there for perhaps an hour, then gone. Same for RI. VE3 was there for about an hour. After dinner, I returned to the shack to see a screen full of JA. It was roaring for at least an hour -- but around 10:20 PM local, it quickly faded. A great place to see (and study) this is this map. It stays in my browser during Es season (roughly May to July in NA).

Yes, CW is MUCH faster -- IF there are good ops on both ends. But FT8 also goes at least 6 dB deeper into the noise than CW, and CW is at least 10 dB better than SSB. I worked 40 new grids last season, and 40 new ones this season. Last season, all but three were worked with WSJT-X.? Eight were MSK144 to two hams doing grid trips. The rest were evenly split between JT65 and FT8. This year I've ONLY worked FT8. I estimate that at least half of those 80 grids have no hams who work CW and are active on 6M. 73, Jim K9YC On 6/21/2018 1:34 PM, gregg.w6izt1 at gmail.com wrote: > I'm not convinced of the merit of FT8 when trying to work multi hop E skip. > It takes too long to complete and exchange and propagation is constantly > changing.

Pin 8 is the "Power On" pin. Pulsing that pin low will cause a KPA500 or KPA1500 amplifier to power up. Powering up the K3 could cause such a pulse if you have the wrong cable connected between things. Pin 8 of the KPA1500 and KPA500 could also be connected in parallel to each other. Solution: use an Elecraft AUX cable, not a 15-pin cable or VGA monitor cable, between the Y-BOX, the KAT500, and the KPA1500. This cable has no connection on the power on pin. The recommended way to correctly connect these devices together would be: K3 ACC Port -> 15 pin M/M cable -> Y-BOX input Y-BOX v1.3 Output 1 -> Elecraft M/F AUX cable -> KAT500 -> 15 pin M/F cable (or another AUX cable) -> KPA500 Y-BOX v1.3 Output 2 -> Elecraft M/F AUX cable -> KPA1500 Y-BOX v1.3 Outputs 3/4 -> Other devices (Band Decoder, MK2R+, RemoteRig etc.) Some Elecraft AUX cables were modified to short Pin 11 (DIGOUT1) to Pin 8 to allow for remote power on. If you bought the cable second-hand, it may have been modified to do that. FYI, for Y-BOX v2.1 (upgrades available), only one Elecraft AUX cable would be needed to connect all three devices (KAT500, KPA500, KPA1500), because the new Y-BOX v2.1 has one dedicated "AMP AUX" port, which by default has no connection in pins 1, 4, 6, 7, and 8, same as the AUX cable). So it can be wired like this: K3 ACC Port -> 15 pin MM cable -> Y-BOX input Y-BOX v2.1 AMP AUX Output -> 15 pin M/F cable -> KAT500 -> 15 pin M/F cable -> KPA500 Y-BOX v2.1 Output 2 -> Elecraft M/F AUX cable -> KPA1500 Y-BOX v2.1 Outputs 3/4 -> Other devices (Band Decoder, MK2R+, RemoteRig etc.) 73, Bob, N6TV https://bit.ly/Y-BOX ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k9yeq at live.com From g4gnx at g4gnx.com Thu Jun 21 18:35:10 2018 From: g4gnx at g4gnx.com (G4GNX) Date: Thu, 21 Jun 2018 23:35:10 +0100 Subject: [Elecraft] Transverter calibration In-Reply-To: <491FB43E-E427-48D1-AD25-82F48AF1B774@voodoolab.com> References: <491FB43E-E427-48D1-AD25-82F48AF1B774@voodoolab.com> Message-ID: <26C0261A4CFE49AD828F851A5DDDD114@G4GNXLaptop> I built a K3S a few months ago and I've installed the K144XV 2 metre transverter into it, along with the K144XV Ref lock option.

It's important to understand how E-skip works. It's called "sporadic E" because it depends on sporadic activation of the layer for reasons that are not understood by me. Propagation from E-skip is often "spotlight" in nature, especially when more than one hop is involved. We can work "single hop" when the ionized cloud is roughly midway between us and the other station; for two or more hops, at least two ionized clouds must line up -- that is, ground to cloud one to ground to cloud two to ground. With double-hop Es, it's common to be able to work stations within a radius as small as 50 miles. And then one or both of clouds moves and a different radius is illuminated. Yesterday, for example, from here near San Francisco, stations 50-100 miles E of me were working China, and stations in TX and OK were working JA. I heard none of it. But at various times, a single skip cloud provided a path down to San Diego and into XE, another into AZ, S NM, and S TX. That was all before noon. Eventually I started seeing the SE US -- AL, FL, SC, GA, NC. Toward evening, we started seeing (and working New England and the upper Midwest (8-land). And so on. VT was there for perhaps an hour, then gone. Same for RI. VE3 was there for about an hour. After dinner, I returned to the shack to see a screen full of JA. It was roaring for at least an hour -- but around 10:20 PM local, it quickly faded. A great place to see (and study) this is this map. It stays in my browser during Es season (roughly May to July in NA).

So here's the ATU issues: I find that the ATU very rarely will learn a setting to get the SWR below 1.2:1 on any band. I can usually tweak it down to 1.0:1 using the Utility Program. And yes, before anybody asks, I have ATU STOP TUNE and the ATU BYPASS set at 1.0:1. On 6M into a perfect load (laboratory quality to 8GHz) with the ATU bypassed, the internal SWR meter reads 1.4:1 I would have expected it to be 1.0:1, but Elecraft tell me it is normal. So the ATU on 6M will have to tune out what is left when the 1.4:1 internal mismatch sees your external antenna mismatch. Maybe this is contributing to your problem. Try adding a quarter wave of coax, maybe it will achieve a better match. Fortunately my 6M antenna is flat enough that I can work CW, SSB and FT-8 in BYPASS. For your interest, on 10M in to perfect load with ATU bypassed the internal SWR meter reads 1.2:1. Not 1.0:1. Another issue I have with the ATU is that the internal frequency counter has 8KHz resolution which according to one of the Elecraft techs can lead to a 16KHz error in measurement. It appears that during "learning" that the ATU is based on the internal frequency counter measurement, not the frequency you transceiver sends to the KPA1500.This means that on the bands that have 10KHz or 20KHz segments, you cannot be sure which segment you are using, and when you use the tuner it could be in a different segment. Being off by a segment could be a problem with a high Q antenna. Apparently the counter originally had 1KHz resolution but was changed to fix some other problem. An Elecraft tech told me they currently have no plan to change it back to 1KHz. I am not suggesting that the tuner should change segments exactly on their edge. Clearly there has to be some hysteresis to stop hunting. 25% of a segment width might width be a good number to choose, but this would require the current frequency counter to have improved resolution. - Paul KW7Y At 08:53 PM 6/21/2018, K9MA wrote: >Dick, Have you tried manually adjusting the >ATU??

About 2002 it was stated there were 3802 licenced hams residing in AK. Now you know half of them never get on at all. Out of the other half 50% do only HF: the other 49% do only VHF-FM. That leaves 1% maybe 38 hams spread over an area 2-1/2 times the size of Texas. In fact there are spread. 50% of the state's population lives within 100-miles of Anchorage (pop 370K), then Fairbanks (about 80K). 6m Es work into the Fairbanks area more often than south of there. KL7NO is well known 6m op up there. I live 65-miles south of Anchorage (KL7KY and KL7HBK who are devout sixers) often have Es and I don't or vice versa. Then there are hundreds of square miles without anyone (let alone a ham). Who you gonna work out there on the Tundra? A Cariboo or Bear? Es do no good it not landing in the very limited populated locations. Then Es are (evidentally) more common in lower latitudes. The *real* answer is EME. Prop is open for eme when the moon is up; happens every day. Yes, there are parameters that make eme better or worse so maybe say is available half a month, every month. And that is why I am building a two-antenna 6m eme array. So all you down there can achieve WAS. I will not be QRV until September with new array. 73, Ed - KL7UW http://www.kl7uw.com/6m.htm "My question would be how (m)any KL7's did you work? 99% of openings do not happen "Up here"." And that is my problem! Only Alaska left to work for 6 m WAS and it seems that even in the best openings there are very few Alaska stations even listening. Yesterday I did see that KL7KY and KL7HBK were shown as FT8 listeners by PSKReporter but I couldn't raise either. That was on a day that I worked Canary Islands in the afternoon and Japan in the evening. So what is the the magic set of circumstances that opens a 6 m path between AK and AZ? 73, Andy k3wyc 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From pincon at erols.com Fri Jun 22 07:58:06 2018 From: pincon at erols.com (Charlie T) Date: Fri, 22 Jun 2018 07:58:06 -0400 Subject: [Elecraft] FW: Seems That 6 Meters is Some What Open In-Reply-To: <0ECC2EE1-0A23-4C9B-A0D9-B5E22AE5F098@voodoolab.com> References: <010101d409c1$5b27f370$1177da50$@erols.com> <0ECC2EE1-0A23-4C9B-A0D9-B5E22AE5F098@voodoolab.com> Message-ID: <003901d40a20$4bd77670$e3866350$@erols.com> We only have to wait maybe, 5 or 6 years. I think we're at, or near, the 11 year cycle minimum. If you think E openings are great, as the old saying goes, "You ain't seen nuthin' yet" when the F-2 thickens up. Unless the next peak is a wash-out for six meters, there'll be times when you'll think your band scope is stuck on 20M.

Look on page 19. You can adjust the offset with the K3 menu XV1 OFS. The offsets for each band segment should be indicated on the XV144 top cover. If you have accurate frequency beacons available, you can refine those offsets as needed. 73, Don W3FPR On 6/21/2018 6:35 PM, G4GNX wrote: > I built a K3S a few months ago and I've installed the K144XV 2 metre > transverter into it, along with the K144XV Ref lock option. > > Although all of the main K3S calibration is OK, I find that the K144XV is > about 200Hz off nominal frequency, certainly in the 144-146 MHz segment. > > The manuals mention calibration being automatic, so I can't find any > reference to adjustment where the frequency is incorrect. > > Anyone any ideas how I can get the transverter on frequency across the > band?

It has been working, but occasionally I get a message about COM port conflicts, about the two COM ports that are used to control the radios, and this causes problems during a contest such as tomorrow.... I have spent some time looking for the source of conflict, but don't see those two COM port numbers used by anything else in Device Manager, even when using "show hidden devices". When I set up everything related to N1MM, and the u2R I totally avoided using those two COM ports that are used for the radios. I never get the errors when just running the radios without N1MM/u2R. I don't remember any such error from long ago when I was using N1MM without SO2R. I sought advice on a computer forum and a Microsoft employee advised me to try using high port numbers such as 25 or higher for my applications, as any "hidden" usage in Windows would be unlikely to use a high number. No conflicts are reported for the numbers I use for N1MM and u2R, so it seems meaningless to change those to high numbers. It seems I need to try high COM port numbers for communicating with the radios. How can I do that? Using the Elecraft FTDI adapters.

I do have a KPA500 and KAT500 so I think I can comment.? In my opinion, the function of these tuners is to provide a match into which the amp can deliver full power.? If 1.5:1 does this, then that's good enough in my book.? Furthermore, a better match might entail higher tuner losses.? So why worry about it? Another thing; a 1.0:1 SWR infers infinite return loss.? To measure infinite return loss, you need a directional coupler with infinite directivity or some mathematical correction derived from very well known calibration standards and no other errors,? So maybe you say, 1.0:1 can't be measured (you would be correct), let's shoot for 1.22:1.?? That's a return loss of ~20 dB.? Now I have no idea of what the directivity of the coupler is in the KAT500 or KPA1500 but considering it has to work from 1.8 to 54 MHz and to keep the numbers easy, 20 dB wouldn't be unreasonable. (Note: I'm only considering the directivity error, there are several others, internal mismatches, frequency tracking, detector non-linearities, etc.) If we measure a load with 20 dB RL using a directional coupler with 20 dB directivity the answer can be anywhere between infinity to 14 dB.? (Full cancellation of the two reflection coefficients to the sum of the reflection coefficients)? In SWR terms, a 1.22:1 load can measure anywhere between 1.0:1 and 1.5:1.? A "perfect" load will measure 1.22:1. Folks, these things aren't laboratory instruments and until Elecraft builds in vector network analyzers with full error correction this is what we get. Wes?

Once the proper settings are made in the CONFIG menu, the calibration occurs automatically as both oscillators are phase locked to the master K3REF oscillator in the K3. Enable the calibration as follows: Be sure you have K3 Firmware ver. 4.42 or later installed. Tune the K3 to any frequency in the 2-meter band. Hold CONFIG to access the CONFIG menu and select XVn OFS, where n is the transverter number you assigned to the K144XV (see Enabling the K144XV Module in the K144XV Installation and Operation manual). Tap the 0 switch until you see REFLOCK on the K3?s LCD. The automatically calculated offset will appear in upper half of the K3?s LCD. This enables reflock for both the 144 and 146 MHz band segments. You don?t have to repeat the procedure for each segment. If the K3 EXREF option is also installed, the K3?s reference oscillator itself will be automatically calibrated by the external 10 MHz reference. In this case, enabling REFLOCK for the K144XV module will allow the K144XV frequency to track the external reference. The accuracy of the 2-meter frequency will be less than that on HF by a factor of about two, due to the higher frequency of the K144XV local oscillators. I have that installed in my K3 along with the EXTREF module driven by a 10MHz GPSDO. From a cold start the automatically calculated offset can be seen to change +100Hz as the TCXO drifts with warm up. Belief and reality ain't necessarily the same thing.

I just got back from 'experimenting'! I turned the Reflock off and manually set the offsets according to the figures on the Xverter top. With the Reflock still turned off, the discrepancy is several KHz (I did not note the exact figures). With the Reflock turned back on, the discrepancy is back to around 200 Hz and there's no way to manually adjust that in software. I wonder if the K144XV itself is a tad off?

This means you have to keep adjusting the power control within a single band. This appears not to occur if the SWR is 1.1:1 or better. I don't know, but I would guess a solid state untuned amplifier efficiency is better into a 1:1 SWR than a 1:5:1. This could lead to the dreaded more fan noise. By the way by suggesting 1.0:1.

My test data for my KPA500 show there is a very significant difference in PA dissipation and also in harmonic output for loads giving indicated 1.4:1 SWR and loads giving 1.0:1 SWR. When I have a more complete data set I'll make it available for peer review.

The CP1 seems to be representative of Elecraft directional couplers across the line. There's a picture of the W2 high power HF coupler in the manual, it's just larger cores. Sweeping a 20 dB CP1 across the band with a VNWA with a 60 Ohm load, 1.2:1, results with a relative constant -40 dB reflected gain and a -20 forward gain. A closer match to 50 Ohm fall's apart with a wide -40 db to -70 dB dip at 7 MHz reflected across the band at 50 Ohm. I can agree, 1.2 : 1 is about the limit.

If there are other detrimental issues with greater load mismatch then they might need to be addressed.? Unfortunately, Elecraft doesn't specify a load requirement for rated output.? Gain ripple that you observe is possibly a reflection (no pun intended) of the LPFs rather than the intrinsic performance of the transistors, although as I have reported elsewhere K3S IMD is frequency sensitive, but not overly so within a band. One point I would like to make is that guys who wring their hands because the SWR meters on the K3, KAT500 and KPAs all read differently should lighten up.? There are reasons why this can be without there being product defects. Wes?

Paul Kiciak, N2PK, mentions in his paper, "An HF In-Line Return Loss And Power Meter", that this coupler suffers from poor input match at lower frequencies.? So the SWR meter has high SWR!

If there are other detrimental issues with greater load mismatch then they might need to be addressed.? Unfortunately, Elecraft doesn't specify a load requirement for rated output.? Gain ripple that you observe is possibly a reflection (no pun intended) of the LPFs rather than the intrinsic performance of the transistors, although as I have reported elsewhere K3S IMD is frequency sensitive, but not overly so within a band. One point I would like to make is that guys who wring their hands because the SWR meters on the K3, KAT500 and KPAs all read differently should lighten up. There are reasons why this can be without there being product defects. Wes?

SWR reduces this to a single variable, that doesn't even respect the sign of the deviation from the ideal load. That means that efficiency may even be better than the nominal efficiency at a particular SWR, whereas that same SWR can also produce a lowered efficiency. (Similarly, an SWR may destroy a PA or be safe, depending on the fine details.) In particular, a higher load resistance may result in a higher efficiency, at the expense of a lower maximum output. There is actually a K2 build option, that winds the output transformer to impose a higher load resistance, in order give better efficiencies at low powers. Tuning across the band will change at least the reactance component of the load on the PA. Also, if input SWR isn't 1:1, I think you will find that the measured forward power doesn't reflect what is actually available to go out through the antenna. Whilst some of it will circulate back and forth and eventually make its way out in the right direction, some will also get absorbed by the PA.

With the Reflock still turned off, the discrepancy is several KHz (I did not note the exact figures). With the Reflock turned back on, the discrepancy is back to around 200 Hz and there's no way to manually adjust that in software. I wonder if the K144XV itself is a tad off?

I bought this MTR5B "MountainTopper" new from LNR Precision ($400) a couple years ago. Used it when I went to visit my sisters & neices in Florida and Louisiana with excellent results. I did add the optional tuning encoder (I grew up turning knobs for tuning rather than Up/Down button pushing). Also included in the package will be an MFJ 9201 "QRPocket Tuner" which will actually handle 100 watts when tuned at lower power. Original power cable with added "Deans Connector" + matching Deans female as well as a package of spare power connectors to fit the MTR5B. Main power cable has 2 series Schottky diodes in series with the + side to drop a 13.8V power supply to just under 12 V which is the stated max input voltage for the MTR5B. Rig puts out just under 5 watts on 11.9 volts and cosmetically it's a 9 out of 10. It has some scratches around one sides mounting screw hole that happened when I drilled the hole for the encoder. The good news is, Ihave a brand new case for it, still in the box which will be included. The manual is downloadable from LNR Precision's website but I have the original one which has the schematic in it. The one on LNR's website is very abbreviated. A printed copy of the original will be included. Asking $325 Shipped in the US for everything. Anyone interested please contact me off list, (w0eb at cox.net) for pictures, to say "I'll Take It" or for further information. Payment by USPS Money Order or Pay Pal would be preferred.

Apologies for it being a bit long. My K3 is fitted with the line up REFLOCK, EXTREF (10MHz GPSDO) and KTCXO-3 +/-1ppm. In the past I have done several warm up runs from cold start to to T+4 hours where for all practical purposes KTCXO-3 drift as measured by the EXTREF module stopped. The results are repeatable with small variations, cold start temperature and room temperature were a reasonably consistent, +23C. Front panel temperature change gives a reasonable indication of the warm up environment of the KTCXO-3. My KTCXO-3 at power up starts at 49.379.836 on average and after warm up stops drifting at 49.379.890. It goes through two plateaux phases the first at T+5 minutes (49.379.863) until T+26 minutes (49.379.865). It then starts a slow rise to T+120 where after it enters the second plateaux (49.379.884) where after there is little change. This is repeatable. However, it must be noted that this is my KTCXO-3 other units will have their own characteristic, even drifting in the opposite direction. I was unable to programme my GPSDO for both 10MHz and 145.5MHz outputs, maybe a forbidden combination, must get to grips with this. So I decided to do a run with a sniff of the 145.5MHz signal fed into the 2m input and the K3 not locked to an external source. The manual REFCAL setting was at the top end of the drift range (49.379.886). After cold start and a quick tune to the 145.500.000 signal the initial dial reading had to be set 176Hz high. There after retune took place for the first hour at one minute intervals and the dial error recorded. Retune was accomplished by offsetting the dial slightly LF and netting with TAP SPOT. There is a small 3Hz difference between netting from LF or HF using this method so for consistency LF was always used. The change in dial reading was consistent with the previously measured warm up drift characteristic of my KTCXO-3: T+1 +176Hz T+5 +98Hz T+28 +86Hz T+60 +17Hz T+80 +11Hz T+100 +9Hz T+120 +8Hz T+180 +4Hz T+240 +1Hz At T+240 the manually set REFCAL frequency and the true drifting frequency of the KTCXO-3 will have converged. The dial frequency and the signal frequency has also essentially converged. When I figure out how to programme two frequencies out of my GPSDO or find a suitably stable 2m source it will be interesting to run the same test with my K3 EXTREF locked. There is great faith placed in digital displays to tell the truth, however, there are factors at play which can render this truth to be a little coloured. Any radio with a free running reference oscillator for example will be in error at some point. I standby to be shot down.

It has been working, but occasionally I get a message about COM port conflicts, about the two COM ports that are used to control the radios, and this causes problems during a contest such as tomorrow.... I have spent some time looking for the source of conflict, but don't see those two COM port numbers used by anything else in Device Manager, even when using "show hidden devices". When I set up everything related to N1MM, and the u2R I totally avoided using those two COM ports that are used for the radios. I never get the errors when just running the radios without N1MM/u2R. I don't remember any such error from long ago when I was using N1MM without SO2R. I sought advice on a computer forum and a Microsoft employee advised me to try using high port numbers such as 25 or higher for my applications, as any "hidden" usage in Windows would be unlikely to use a high number. No conflicts are reported for the numbers I use for N1MM and u2R, so it seems meaningless to change those to high numbers. It seems I need to try high COM port numbers for communicating with the radios. How can I do that? Using the Elecraft FTDI adapters.

Despite temperatures in the mid-90?s and blistering sunshine, we had many visitors, including a lot of curious non-hams. This tends to be a social event with lots of conversation and ad-hoc experimentation with radios and antennas, so I won?t be bragging about our claimed Field Day score. Still, a good time was had by all, with vast quantities of water and other liquids consumed to avoid heat stroke. Late Saturday afternoon I undertook a brief solo trek to exercise the KX2. I had intended to climb a nearby hill. Given the outrageous temperatures, I settled for a picnic table on the other side of the parking lot, beneath a large oak. Normally I would have tossed a wire into this tree. Instead I used a prototype 2-band, 4? whip, in keeping with the ?two QSOs per foot challenge? we proposed in a recent Elecraft newsletter. I made 10 QSOs over the course of about 20 minutes (that?s 3.00 Q/ft, for those keeping score), ranging from KH6 to the East Coast. Overall, conditions were not thrilling. 20 meters was pretty much single-hop until Saturday evening. 15 m was deceased until this morning when, back at the home QTH, I noticed things picking up on this band around the same time as some sporadic-E kicking in on 6 m.

I believe John was referring to external band-pass filters of the type used in multi-transmitter stations that may be operating at high power into antennas in each other?s near-fields. The K3S and K3 can survive a lot of abuse of this type; it includes built-in signal detection and shut-down of various RX stages. But pumping many watts into the front end (due to tight antenna coupling) is never a good idea. 73, Wayne N6KR > On Jun 24, 2018, at 4:10 PM, donovanf at starpower.net wrote: > > The K3 and K3S have built in transmit and receive bandpass filters. > Unfortunately their performance data is unpublished. > > > > http://elecraft.com/manual/K3_Schematics_Jun_2010.pdf > See the third page > > > > David hasn't shared what the specific circumstances may have > caused the HI SIGNAL response.

Prior to that, I had a screen full of JA decodes on 6M, but after, I had none. Returning from FD, I put the KX3 into an old HP generator of unknown calibration, and, for comparison, also fed the RX in of my K3. 50uv at 50.09 MHz gave S9 on the K3, but only S5 on the KX3 with the preamp off and 5 dB over S9 with the preamp on. I can clearly hear the preamp turning on and I could hear -143 dBm (the lowest level to which I can set the generator). So, the question is, is this "normal?"? Is it possible that a protection diode has fried? This is major physical effort for the four guys carrying a complete station up a 3 mile trail that gains 1,000 ft, so I want to make certain that they're taking a good radio. :) 73, Jim K9YC From n6kr at elecraft.com Sun Jun 24 20:06:51 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 24 Jun 2018 17:06:51 -0700 Subject: [Elecraft] KX3 Tech Question In-Reply-To: <4d758924-2f0b-1831-eb3f-9de28c9f3610@audiosystemsgroup.com> References: <4d758924-2f0b-1831-eb3f-9de28c9f3610@audiosystemsgroup.com> Message-ID: <5EA8465F-C1CC-4569-9845-8527D4A1252A@elecraft.com> Jim, S9 (or S9+5) is in the right ballpark with a 50 uV signal. This applies to the preamp-on case for all of our rigs. Also, if you can hear a -143 dBm signal, you?re doing just fine :) I suspect there?s some other reason for the loss of decodes on 6 m. Make sure you weren?t in SPLIT, didn?t turn off the preamp, didn?t turn on the attenuator, and had RF GAIN set to -0 dB. Also set COR LVL to the default (0.1 W, or +20 dBm). Note that the KX2 and KX3 both have high-signal protective features born and bred during close-quarters HF Pack operation. Depending on the offending signal levels, they will automatically turn off the preamp, turn on the attenuator, turn off an IF gain stage, or even open all of the LPFs. We?ve tested these features by injecting levels up to 10 W directly into the antenna jack. 73, Wayne N6KR > On Jun 24, 2018, at 4:53 PM, Jim Brown wrote: > > While setting up for a grid expedition next weekend, I fear that W6GJB and I may have blown up the front end of my KX3 -- transmitted 1kW FT8 into a Yagi within 100 ft of the antenna connected to the KX3.

"Electrons," I answered with a straight face. His face broke into a big sunny smile. Turns out he's not only interested in hamming himself but also runs a private girl's school and they are heavy into the STEM thing (no "A", please) and we ended up our f2f by making plans for a Skype session for the girls for later this year for me to chat about that voodoo that we do. I did offer him a GOTA session. Sadly he never made it over. He was busy opening cabins and getting his properties ready for the summer. After I was done and packed up, the nieces and nephews took a page out of my kids' playbook by chanting "Whiskey Charlie Three Tango" for the rest of the weekend. Hey, I've been called worse.

Lots of rain but good times. Quite a positive education for all, esp the hardcore CW ops accustomed to 100 Watt contest stations. Ended up logging on iPads (Hamlog) syncing to a Raspberry Pi Zero Server - which the Operators found easy in power but the lack of automation proved tedious. (We should have implemented the Piglets) That?s ok, we automated with people! Everyone had very good things to say about the KX2. Fantastic experience and the bands were kind to us.

I made 10 QSOs over the course of about 20 minutes (that s 3.00 Q/ft, for those keeping score), ranging from KH6 to the East Coast. Overall, conditions were not thrilling. 20 meters was pretty much single-hop until Saturday evening. 15 m was deceased until this morning when, back at the home QTH, I noticed things picking up on this band around the same time as some sporadic-E kicking in on 6 m.

I have a Genovation 64 Key programmable keypad working that fires macros into the SVGA, at the push of a single button. See: https://www.nk7z.net/adding-external-keypad-k3/ I fire all sorts of prebuilt macros into the P3, from reconfiguring the rig for various modes, to setting up complex split operations for DX, to sending my call in CW. I program the Genovation once, (and never touch it again programming wise), then just add my macros to the P3 after that. Once a macro is added, that macro is available at a single button press from then on. Works great in a pileup. I press the "Split Plus" button on the Genovation and the P3 moves the tuned DX signal to the hard left side of the P3 display, sets the span of the P3 to 5 KHz., (showing me the 5 KHz. above the DX signal), turns on VFO B for control of my my transmit on the K3, narrows the K3 filter to 100 Hz., (centered on the DX signal), centers the IF passband on my DX signal, and then shows the transmit cursor on the P3. This lets me find a hole in the pileup, use the VFO B knob on the K3 to move my transmit to that hole in the pileup, and when I hit the ID button it fires off my ID as fast, and as often as I press the button for ID. The entire operation takes about 2 seconds to set up, and start calling... 73s and thanks, Dave NK7Z https://www.nk7z.net On 06/25/2018 05:29 AM, N4OI - Ken wrote: > > I have a P3 and will be ordering the P3_SVGA.

Reason for request: The macro capability of the K3/P3 seems very underused. In general it is an enormously powerful tool, but the process of loading macros into the P3 is at best, 1980ish, and and at worst reminds me of keying in ones and zeros into my old IMSA 8080 machine to program it way back in the day. I suspect very few folks are using macros launched from the P3, because of this. Something like the Frequency editor, (only for Macros), would be grand, but ANYTHING that allows for off-line macro creation and testing, then automating the upload precess would be vast improvement over the current 1970ish process that exists today. -- 73s and thanks, Dave NK7Z https://www.nk7z.net From dave at nk7z.net Mon Jun 25 11:01:18 2018 From: dave at nk7z.net (Dave Cole (NK7Z)) Date: Mon, 25 Jun 2018 08:01:18 -0700 Subject: [Elecraft] P3_SVGA Wireless KB Support?

The Logitech Unifying receiver plugs into the P3SVGA?s USB port and just work. Recent keyboards such as the K380 give you additional features - you can also use the keyboard with up to two additional devices. This can be used to control both the P3 and the shack computer (and maybe a second P3 for SO2R). These keyboards have a set of three buttons that allow you to select one of three devices they are directly communicating with. In my test setup I have the device 1 button switch to the P3 (on my left) while the device 2 button selects the computer. The keyboards can use both Unifying and BLE for communications. For use with my older Mac (which does Bluetooth but not BLE) I acquired a second Unifying receiver to allow it to use the keyboard. There are several styles of keyboards at various sizes which allow you to fit the keyboard to your desk. Note that you will need one of the newer keyboards that have the Unifying receiver. The company makes quite a few bluetooth-only keyboards (mostly for use with iPads and Android tablets). These will not work with the P3SVGA. If you have any questions, just give me a shout. 73!

I believe you would be better off putting the rig into DATA A. Set the rig's mode to DATA and the data submode to DATA A. With the rig in DATA A, adjust the K3's filter controls to put the Lo-Cut at around 0.20 and the Hi-Cut around 2.8. With the rig in DATA A mode, set MIC SEL to LIN (this will not affect your microphone setting for voice modes). MIC+LIN will be N/A. Adjust the MIC gain control to somewhere above zero, e.g. LIN 5 or so. In the WSJT-X Settings window under the Radio tab, if you are not using some other radio control software such as the DXLab Suite Commander, then set the CAT control port to the COM port number that Windows has assigned to the K3S's USB serial port. Set the Mode in WSJT-X to either None or Data/Pkt - not to USB. For PTT, I prefer to set WSJT-X's PTT method to VOX and turn VOX on in the K3, or you can use PTT via CAT. Under Split Operation, choose either Split or Fake It. In the WSJT-X Settings window under the Sound tab, select the K3S's USB Audio Codec as the soundcard device for both input and output. Right-click on the Windows speaker icon in the Windows system tray and select Playback devices, then select the USB Audio Codec (in the K3S) and click on the Properties button. Select the Level tab and adjust the level slider so it is in the middle of the range. While receiving in WSJT-X with WSJT-X's Monitor function on, adjust the K3S's LIN OUT level so that band noise alone is enough to bring the level indicator on the left side of the WSJT-X window to about 30 dB or so. When receiving actual signals, the level thermometer should not turn red; if it does, reduce the K3S's LIN OUT level. In the Wide Graph window, you may need to adjust the waterfall and spectrum gain and zero controls to get a good looking spectrum and waterfall. I don't check Flatten - if you do, make sure that the Wide Graph window does not display any frequencies outside the K3S's filter bandpass. Now transmitting into a dummy load or a dead band at low power or in TX Test mode, put WSJT-X into transmit and adjust the Windows level slider and/or the K3's MIC gain control to get 4-5 bars on the K3's ALC meter. Once this is adjusted correctly, you should no longer need to adjust either of these controls. Use the K3's PWR control to adjust the output power. Do not try to control the output power by changing the audio level. Leave the Pwr slider on the right side of the WSJT-X window at the top of its range and don't change it. 73, Rich VE3KI W0EB wrote: For some reason I can't get WSJT-X to pull the input sound or send output sound to the K3S through the USB port.

Here was our layout (well, almost): https://groups.io/g/OCRA-DFMA/photo/39174/1?p=Name,,,20,1,0,0 Installing that many antennas in the requisite 1000 ft circle with minimal mutual interference is a real feat, let me tell you! We even had a sagging 80M OCF dipole tangle with a beam at one point... This year we finally achieved our long-term goal of all Elecraft transmitters.? Our testing over the last few years agrees with the collated test results by K9YC here: http://audiosystemsgroup.com/TXNoise.pdf Although a few years old, his results agree with our tests that the K3 has the lowest in-band phase noise of any we have tested. This has been a real problem in past years, with almost all Yaecomwood transmitters we tried txing intolerable levels of phase noise like this Kenwood (20M, 200 KHz spacing) running SSB from last year as recorded in the CW shack: https://proaudioeng.com/wp-content/uploads/2018/06/Kenwood-tx-phase-noise.mp4 This year we had 7 Elecraft K3s and two KX3s.? The only phase noise issues we had were from the one KX3 running FT8 digi, and mostly ~S3-5 when a beam was pointed towards the digi antenna from ~300 feet away with a 30 KHz spacing.? Other than that we were really pleased to have finally been almost free from the band-shattering noise experienced in previous years.? Kudos to Elecraft for such great Tx performance! Overall the band condx were OK although not great from central NC, although a surprising appearance of 6 and 10 meter propagation helped!? It is always a challenge contesting QRP and it is difficult to break pile-ups, so running as opposed to S&P is often the best bet.? Of course running is not a panacea when QRP, I must have been stomped on a dozen times by others who (to give them the benefit of the doubt) didn't hear me CQing on channel. We once again attempted to wireless network N1MM over all 9 stations, but it became erratic so logging was done in several networked pods instead.? We won't know the total score until the logs are collated. I would say the biggest challenge we faced is one I heard from other groups: it is getting to the point where a lot of heavy lifting (we had 6 towers) is difficult with a bunch of old fogies.? If large FD efforts like W4EZ are to continue youth outreach is not an option.? Nevertheless, at least this year no one was hurt, except for many a branch from lines shot over trees, and many a burger and other refreshments were enjoyed as well!

We were 4A all qrp at 5 W on a local park that?s on an old volcano (Kelley Butte) with elevation and tons of trees. I used my KX3 for 40,20 and 15 CW coupled to a rhombic/loop antenna copied from the June 2017 article by WU0I. You can switch the configuration between a rhombic or a full loop at the end opposite the feed point (450 ohm line). In the article it?s done manually but one of the club guys devised a 24V latching relay we could engage /disengage by sending a pulse through the feed line (disconnected!). I ended up using it mostly in the rhombic configuration as it loaded better and was quieter, and seemed to perform slightly better on 40, my primary band. Still I wasn?t too impressed by its? performance on 40, but I have to say that on 20 and 15 it was outstanding! Almost always one call and I had ?em. 15 opened very nicely for a big run for me Sunday morning around 9 AM (PDT) and I stayed there till the end-worked a ton. Of course the KX3 shone particularly with the filtering-I used the APF a lot and guys were blown away how clear it was. I also noticed a big difference from last year since I installed the roofing filter. I used an amplified speaker system so folks could hear as they came in-next year I need to find a small portable mixer so I can use phones but still allow others to hear. I had the panadaptor as well which was helpful, but I need to learn to use it more effectively in this crowded situation. the other thing that was really helpful was the little wooden stand to mount the radio and panadaptor from the ?NOGA? (North Georgia QRP club) that Marino KE7EMV loaned me. All in all I think I did about 2-250 Q?s with only a 3 hour nap, but next year I plan to have other operators I?m training on CW to spell me.And-there?s another cw station with old gear that I need to switch to another KX3 or K3! My next adventure will be SOTA with the KX2 in Oregon and a couple of QRP Foxhounds where I?m the fox-planning to go to some SOTA sites for these runs in August. All fun!

Right. The concept is to make them "colinear," so each antenna is in the other's null (off the end). We have done exactly that for our CQP county expeditions, where we run K3/KPA500 stations on the same band. Running 7 dB more power requires at least double the separation. Another important component is an effective ferrite choke at each antenna's feedpoint -- that can improve isolation by preventing feedline radiation/reception from filling in the nulls. Careful planning of antenna setup is key to a successful multi-transmitter setup. Since we're on the left coast, we do the same thing you do - Yagis pointed to W2/W3, dipoles broadside in the same direction. Operating from the middle of the country, dipoles are a better choice than Yagis, especially for CW, again oriented broadside E/W. We do QRP FD, CW only, and it's obvious that some stations have paid a lot more attention to RX noise than others. Our club's call is W6BX, and we worked W3AO on at least three bands. Don't know if we made it on 80 -- haven't looked at the log. 73, Jim K9YC From ve2tzt at arrl.net Mon Jun 25 17:45:47 2018 From: ve2tzt at arrl.net (VE2TZT) Date: Mon, 25 Jun 2018 17:45:47 -0400 Subject: [Elecraft] K3S internal USB sound card seen as microphone since new Win10 release ?

Because I recently had minor skin surgery on my head, I was not using my headphones as usual for CW on my KX3. Instead I hooked my SP3 speaker into the headphone jack on the KX3. Volume was fine for the actual signal but the monitor sound level was not very loud. Due to the fact that the band was noisy this morning (20 meters, 14.014 MHz to be more precise) I had significant trouble hearing my own CW via monitor. With monitor volume level turned all the way up, 40 I think, it was distorted enough to be causing ill to my sensitive ears. Is this expected behavior? No preamp on that SP3 connection, direct headphones jack to SP3. With headphones alone and even with the internal KX3 speaker, monitor level is just fine, no problems.

We actually installed twelve 48 foot masts in two 950 foot North/South straight lines separated by 150 feet. We couldn't fit 22 antennas in a single 950 foot line! Mast and antenna installation and deployment of more than 7000 feet of RG-213 began at 10 a.m. Friday and was completed seven hours later. It took less than four hours to dismantle the entire site. Our site is a school/athletic field complex with more than 25 acres of mowed grass and no trees, its slightly elevated above surrounding terrain. This type of school/athletic field complex is very common in Maryland. Its an ideal Field Day site if you have many portable masts. But our VHF ops would still prefer a mountain top location...

We used K6EI for our main call and W6ZZZ for GOTA. This year we were 14A, QRP, battery and solar panel powered. We had the luxury of lots of panels, so we were able to have a 120V utility for running our computers. We also had enough extra power to run our fans etc., as the temperatures on Saturday were in the high 90s (c36C or so). Note, we are not permitted to operate generators at night, so we don't use them at all. We were in category 14A with 3 CW stations, 3 SSB stations, and 2 digital stations on HF. VHF and UHF filled the rest of the transmitter slots. We had separate triband antennas for CW, SSB, and digital with triband filters to allow use of all three bands at once. We also had separate wire antennas for 40M and 80M. GOTA had its own set of antennas. Getting all this set up took the better part of the daylight on Friday. (Thanks ARRL for the rule change that permits early setup Friday when it is cooler.) We minimize interference between stations on the same band by careful antenna placement, running QRP, using Elecraft and Flex gear, and providing adequate voltage to the radios. I could see our CW stations on the P3 while operating digital, but they were just strong CW stations and caused no interference. Our networked N1MM logging system lets us cheer every time we pass a QSO count milepost, as well as providing lots of backup for the logs. Our GOTA operation was quite popular, with QSOs 150% of last year. Since we are next to a popular trail in the San Antonio Open Space Preserve, we get a lot of bicycle visitors. Some know about ham radio and others have never heard of it. It appears our main operation QSO count was slightly ahead of last year, but I haven't seen a full comparison yet. We got lots of people on the air, with some trying new modes for the first time. I counted 21 people who actually made it into the group photo. Everyone had a good time and went home tired. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz | Re: Computer reliability, performance, and security: 408-356-8506 | The guy who *is* wearing a parachute is *not* the www.pwpconsult.com | first to reach the ground. - Terence Kelly From turnbull at net1.ie Tue Jun 26 02:42:39 2018 From: turnbull at net1.ie (turnbull) Date: Tue, 26 Jun 2018 07:42:39 +0100 Subject: [Elecraft] KPOD In-Reply-To: <20180626043132.7339B149A637@mailman.qth.net> Message-ID: <5b31e063.1c69fb81.261f2.4233@mx.google.com> Friends,? ?

This would be correct if the computer was not attached to the rig. Many people use CAT control which makes logging so much easier, in in that configuration one has to run both the rig and APC from battery if claiming battery power status.

My #1 reason for the KPOD? is to get my arm supported by my desk to relieve strain on an ancient shoulder injury.? Pigknob worked equally well for that.? KPOD has a rocker switch that switches the knob between VFO-A, VFO-B, RIT.? There are 8 push buttons, 4 on each side of the knob.? You can use the K3 Utility to program the 16 macros inside the K3.? Tapping the 8 buttons activates 8 of the stored macros.? Holding the 8 buttons activates the other 8 macros.? It also has 4 LED's that you can turn on and off with the buttons to indicate various states.? I haven't messed with them. In a remote configuration with a RemotRig RRC-1258 [and perhaps other configs as well], the KPOD knob and rocker switch work normally, controlling the host radio.? The buttons will activate the 16 macros stored in the host.? This is fine if your remote is yours and no one else uses it.? In a shared station remote environment, there needs to be agreement between all the users as to the actions of the 16 macros. The KPOD is moderately heavy for its size and stays put on the desk fairly well.? The little tilt stand will not allow it to lay flat due to a couple of protrusions, I beefed up the 4 rubber feet with little stick-on silicone "dots" [ACE Hardware] since I use it flat. It would be nice [for me] if the macros were stored inside the KPOD like the Pigknob, but it is meeting my primary need when remote, and all of them when running locally. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/25/2018 9:08 PM, Edward via Elecraft wrote: > Is anybody using the KPOD and if so, seeing it?s benefit? > > 73, > Ed NI6S > From k5hm.ron at gmail.com Tue Jun 26 14:40:42 2018 From: k5hm.ron at gmail.com (Ron Litt) Date: Tue, 26 Jun 2018 18:40:42 +0000 Subject: [Elecraft] All K3 Field Day Message-ID: Down here in Houston four clubs came together for an all Elecraft Field Day.

What equipment at our Field Day site must be operated off of the emergency power in order to claim the 100-point per transmitter bonus? A. You must operate all transmitting and receiving equipment from emergency power. If you use a computer for digital modes, and/or to control or operate the radio, it also must use emergency power. If the computer is used only for logging and is not keying the transmitter, it does not need to be emergency powered. If the pc is not connected to the radio it does not need to be on emergency power. But if the radio is controlled or keyed by the pc then the pc is part of the transmitter and must be on emergency power. I believe that if the pc is on mains power and you use it to key or otherwise control the rig, i.e. run digi, then you should be in the commercial power class. If you can't claim the emergency power bonus then you must be on commercial power, even if the radios are on generators. 73 de dave ab9ca On 6/26/18 2:26 PM, 1lasportsman 1lasportsman wrote: > How would this apply as we had the radio's on generator power? >> On June 26, 2018 at 1:08 PM Howard Hoyt wrote: > > > Buck, k4ia wrote: > >>Only the transmitter has to be on battery power. > >>You can run a computer, air-conditioner and > >>television on a generator or even mains power. > > This would be correct if the computer was not attached to the rig.

I am running Windows 10 and controlling the radio and PTT with Ham Radio Deluxe. It worked well that way. However, a couple of days ago there was a thread on using the internal sound card, and I decided to try it. I have the single USB cable hooked between the radio and the computer. Is that the only connection required? I have the computer and WSJT-X set to USB CODEX both input and output. Decoding and the PTT are working. When I click tune or Enable transmit to send CQ, the rig goes into transmit, and the ALC indicates signal out. However, a second later the transmission ceases. I had already discovered the microphone privacy setting issue and fixed that problem. Any suggestions on what I might be doing wrong?

I posted this to https://groups.io/g/Elecraft-K3/message/29258 on March 31st, but I'll repeat it here: To change the K3 USB sound card to Stereo mode: 1. Right click on the Speaker Icon in the Windows Notification Area (lower right corner of task bar, near the clock) 2. Select Recording Devices 3. Click to select the USB Audio CODEC for the K3 (you may have more than one of these) 4. Click Properties 5. (optional) On the General tab, above the Change Icon button, you can give the K3 USB Audio CODEC a new name like K3 USB AUDIO 6. Select the Advanced tab 7.

I built a new custom cable to feed the speakers from the outputs of my stereo amplifier using the pinout data supplied in the SP3 manual. I also verified that the pinout shown pictorially (in two places in the manual) matched the schematic. Upon installation, nothing worked correctly -- I could only get right channel audio out of one of the speakers. I spent a while troubleshooting last night and resumed this evening. To make a somewhat long story short, I discovered that although the SP3 pictorials and schematic showed that the input connector expected right channel audio on the tip and left channel audio on the ring, the speaker was actually wired for left channel on the tip and right channel on the ring. Strangely enough, this is exactly the pinout shown for the speaker and headphone jacks in the K3 and K3S manuals. The connection from the left speaker output jack to the right speaker input carries right channel audio from the ring on the tip of the interconnect cable. I opened up one of the speakers and verified that it was wired to match the K3 standard. Once I reversed the left and right input sources the stereo pair started behaving as they should. If you're only using one SP3 in a mono configuration it will work just fine; it's only when you try to connect a pair in stereo that the documentation error becomes troublesome. I'd be real curious to know how the SP3 docs got to be so wrong. This problem should be corrected ASAP. 73...

Figure 2 in the SP3 manual has it backwards. The Elecraft K3 and SP3 both follow the standard convention for a TRS or "stereo" connector: Tip = Left Ring = Right (an alliteration that's easy to remember) Furthermore, when using TRS-to-RCA patch cables: White = Left Red = Right (another alliteration that's easy to remember) However, I have several cheap TRS to RCA patch cables that reversed the colors (that's whey they were cheap). Always use a continuity checker to verify that Ring connects to Red, Tip to White, Shield to Shield, an no shorts. Figure 4 looks correct though, because it's talking about the cable on the OUTPUT connector for second SP3, which must be placed on the RIGHT, and it says a MONO cable can be used, so tip = RIGHT makes sense in that context only. I agree that the labeling of R and S (Ring and Sleeve) appears reversed in the schematic. It's the TIP (VFO A, left channel) that goes to the speaker, not the RING. Of course everything gets mixed up if CONFIG:L-MIX-R isn't set to A b. 73, Bob, N6TV On Tue, Jun 26, 2018 at 7:45 PM, Randy Farmer wrote: > I just received a new pair of SP3 speakers and began their installation > last night.

The K3 cannot be fully upgraded to a K3s, and what all 'can' be done depends on such things as: Do you already have the new synthesizer board or boards, depending on having the sub receiver or not. And, are there options that you do not want. Perusing the Elecraft website will give you a pretty good idea, and if you have questions just email support and discuss what you have, what they can do, and what you want... then they can give you a much better idea than I can. I already had the new synths in my K3, and the upgrades I opted for came in at close to, but somewhat under $1000 including shipping.

Sorry for the length of this post: Its a bit complex and I needed to let people know that I *think* I know what I'm talking about! {'-) k ??? Well, while Field Day 2018 is now in the past, I am having some concerns about my KX3. This is a little hard to explain, but here goes! ??? Our setup was in, unfortunately, a fairly high noise area. I was working 20 CW. The noise level was S3, with times reaching S6. I believe, "normal" would be closer to S1. And, of course, lots of signals all over the board signal strength wise. Many of them very strong (10 to 20 over 9!). Also note that this unit has the crystal filters and ATU. I also have the KPA100, which also has the built in ATU. I upgraded the KX3 software to the latest just last week in preparation for FD. Okay, that's the setup. Here are my observations: ??? First, my KX3 has "some" opposite side band bleed through. On 20 CW, I believe it is using the equivalent of lower side band (as you tune from higher to lower frequency, the CW notes go from "high" to "low"). As you pass through zero beat, on reasonably strong signals, a "ghost" signal can be heard going from "low" to "high", but it is very attenuated. This is what I consider "normal" (or perhaps "average") operation for a KX3 as configured. But, there's more... ??? I started to notice that, as I was tuning "down" the band (from higher frequency to lower), there were several "artifacts" (for lack of a better word). First, the several things I noticed were "in sync" with the expected behavior of pitching from "higher" to "lower" as I tune the Rx frequency from "higher" to "lower". So, as far as I understand, /_not_/ opposite side-band "bleed-through." The first artifact seemed to mimic a signal, but it had a distinct difference, which I'm at a bit of a loss to describe. Let's just say "muffled," though that's not accurate. If I remember correctly, it was always a strong signal and seemed to shift with changing frequency properly. I could recognize it, so at least I knew it and could ignore it. Now for the coup d'etat... ??? I also noticed that I was apparently receiving "ghost" signals that were about 500 (or so) Hz between. These signals seemed identical to each other. With the large number of signals on the bands, my bandwidth was narrow - between the tightest (I believe 50 Hz?) and a maybe 1 k. This is the artifact that bothers me. I have no idea which one was the "real" signal (like something from the old "What's My Line" TV show!). So, here's my question: Has anyone noticed something like this before? Is this some sort of configuration issue or is it hardware, or maybe it's just me (!). I don't know if I can reproduce it, so... ??? Anyway, any input is appreciate it. Thanks! ??? kurtt, ???

Some of us, and likely many more ops, need the ability to control the amp from a remote desktop without the need of desktop replication software like TeamViewer and VNC. N4CC and I share his KPA1500 at a remote and while the KPA1500 setup utility gets the job done, it's a poor user experience. What's needed is a highly graphical client/server application similar to the type designed by Bernd Koch, DF3CB for the Alpha 87A amplifier. That package has client and server components, and the GUI is a high-resolution graphic of the amplifier complete with switches, LEDs, panel graphics, even the logo. Clicking on the GUI is just like finger presses on the actual amp. It would be great to utilize the KPA1500's Ethernet port but even client/server connectivity via USB is fine for now -- just to get something going other than the KPA1500 setup utility. I'm willing to help finance the development to get something moving along now and not some TBD date in the future.

Also moved the DVR to the K3s. Then I upgraded, did, all the mods to the K3 that kits were available for including the USB update. However, I did not upgrade the synthesizers. I used the K3 and the K3s the way I used them and feel more than satisfied with the K3 as a spare rig. My K3 is a 4xxx serial number from about 2010 and has the gold plated connectors. I did not buy the tuner for the K3s because I never used the one in the K3. I didn?t move it over either. The new tuner is improved and would just buy it if I felt I needed one. There are a few things that cannot be improved on the K3, like the audio amp, but I don?t seem to miss them when using it.

As for not exchanging yours after a month, it is not COSTCO... How far in advance should they stop selling one product before its replacement comes out? How far back should they be willing to do an exchange? I fear there are no good answers for a small company that needs some cash flow to keep progressing during development; nailing down exact dates for FCC acceptance and supplier readiness and so on can be difficult, and besides, I have learned to measure the goodness of my purchase decisions based on "was it a good decision based on all information available to me at the time?".?

If you are strictly a casual operator, those qualities may not be important to you, but if you are a DX'er or a contester, or otherwise operate in crowded band condition, those things should be important to you. 73, Don W3FPR On 6/27/2018 9:03 AM, hawley, charles j jr wrote: > I decided to bypass the replacement of the synthesizers.

I was working split on 40M, TXing on the TS990 Sub Frequency and RXing on the TS990 Main frequency. All worked well. After the QSO I switched the TS990 Main frequency to 20M to listen around. The Main is still selected RX and the Sub still selected for TX. I heard the KPA1500 going click click click ..;, looked over and saw it going back and forth between 20M and 40M; it couldn't decide which band to be on. I would have expected the KP1500 to go to the TX band and stay there. I will try turning off the logging program, add a wire to the XVR connector for TXD, and set the KP1500 to poll the TS990 and see what happens then. - Paul From huntinhmb at coastside.net Wed Jun 27 11:40:43 2018 From: huntinhmb at coastside.net (Brian Hunt) Date: Wed, 27 Jun 2018 08:40:43 -0700 Subject: [Elecraft] KX3 - Strange Behaviour In-Reply-To: <0d1619fb-527a-4889-bf5f-7a519dc6ed39@pinrod.com> References: <0d1619fb-527a-4889-bf5f-7a519dc6ed39@pinrod.com> Message-ID: Did you have the NB on?

The MAIN and SUB VFO's can be on the same band and have a similar problem. If the frequency is different by more than one KPA-1500 ATU segment and you are TXing on the SUB frequency, then the ATU will switch continuously back and forth the between the two frequencies. This means you can't go split (TXing on the SUB) when using the ATU, by more than 10KHz on 160M and 20KHz on 80M-12M. - Paul KW7Y My KPA1500 is "sniffing" the frequency that is being sent by the TS990 to my logging program. I was working split on 40M, TXing on the TS990 Sub Frequency and RXing on the TS990 Main frequency. All worked well. After the QSO I switched the TS990 Main frequency to 20M to listen around. The Main is still selected RX and the Sub still selected for TX. I heard the KPA1500 going click click click ..;, looked over and saw it going back and forth between 20M and 40M; it couldn't decide which band to be on. I would have expected the KP1500 to go to the TX band and stay there. I will try turning off the logging program, add a wire to the XVR connector for TXD, and set the KP1500 to poll the TS990 and see what happens then. - Paul From mlmurrah at mac.com Wed Jun 27 12:39:21 2018 From: mlmurrah at mac.com (Lee Murrah) Date: Wed, 27 Jun 2018 11:39:21 -0500 Subject: [Elecraft] Issues Using K3S nternal Sound Card for FT8 Message-ID: <31D61368-5581-4210-A133-0AB91968085C@mac.com> Thanks for the suggestions.

The new synthesizers make a big improvement - If I recall it is an 8 to 10 dB improvement in the receive noise floor.

When you press the OFF button on the front panel the control circuitry is still active. This permits software to remotely power up the amp. If you turn off that rear switch all power is removed from the amp; the same as pulling the plug from the wall socket.

Very nice indeed. Very capable. As I integrated it into my K-Line station (K3s, P3 with TX Mon, SP3, KAT500) I immediately noticed that the KAT500 does not have the same height feet on it as any other cabinet in the K-Line. Whatever it is placed next to it sits a bit over 1/8? lower. I realize that it probably does match the W2 wattmeter but with four other SWR measuring devices (K3s, P3/TX Mon, KPA500, KAT500) I really didn?t plan to buy one of those just to even up the cabinets :). So for us OCD folks maybe it would be possible to include both height feet in the kit so that it could match the rest of the product line when desired.

When choosing those com ports, I avoid the com port numbers already in use for radio control, as well as any others that I might find to be in use by looking at Device Manager. If the MicroHAM router can do anything to change the radio control physical com ports, I have missed it. Thanks for your input, and also thanks to others who have replied to my question. Exhausted after FD, I will need some time to recover before considering each piece of advice and otherwise looking at this issue again. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of john at kk9a.com Sent: Sunday, June 24, 2018 8:58 AM To: 'Elecraft Reflector' Subject: [Elecraft] How to change K3 COM port to a high number (to avoid N1MM/u2R problem) Doesn't the MicroHAM router control the com ports? You should be able to set it to anything you want in the router. I have had no issues using Com 1, 2 and 3 with Writelog. John KK9A K7TV wrote: I run two K3 radios with MicroHAM u2R for SO2R in N1MMplus. It has been working, but occasionally I get a message about COM port conflicts, about the two COM ports that are used to control the radios, and this causes problems during a contest such as tomorrow.... I have spent some time looking for the source of conflict, but don't see those two COM port numbers used by anything else in Device Manager, even when using "show hidden devices". When I set up everything related to N1MM, and the u2R I totally avoided using those two COM ports that are used for the radios. I never get the errors when just running the radios without N1MM/u2R. I don't remember any such error from long ago when I was using N1MM without SO2R. I sought advice on a computer forum and a Microsoft employee advised me to try using high port numbers such as 25 or higher for my applications, as any "hidden" usage in Windows would be unlikely to use a high number. No conflicts are reported for the numbers I use for N1MM and u2R, so it seems meaningless to change those to high numbers. It seems I need to try high COM port numbers for communicating with the radios. How can I do that? Using the Elecraft FTDI adapters.

I've had a KPA500 for quite some time, so I have an idea of what constitutes "normal." In the last few months I've noticed that every morning, between roughly 9-10 AM, I hear brief 1-5 second pulsations of easily audible hum emanating from the KPA500. The pulsing events last perhaps 30 seconds to a minute, and may happen more than once. Yes, this ceases if the power cord is out or the power switch on the rear is OFF. But again, it is brief-lived when it occurs, and it's new. To me, guessing, it sounds like something connected to the main AC feed is coming up out of phase, then finally syncing, after which the hum stops. A neighbor's solar array? I have no idea as of this point. 73 Chris NW6V >Message: 23 >Date: Wed, 27 Jun 2018 12:48:19 -0500 >From: Bob McGraw K4TAX >To: elecraft at mailman.qth.net >Subject: Re: [Elecraft] KPA500 Noise While Off >Message-ID: <47eb73a6-cc2f-5fd6-4318-17e76867d441 at blomand.net> >Content-Type: text/plain; charset=utf-8; format=flowed > >Although the front panel switch is OFF, the control circuit of the power >supply remains ON as long as the rear power switch is ON or power is >applied.?

(I've asked about it time or two). Also the main 4-layer RF board has never been listed for upgrade, Which is a shame, on both. I understand the main board ? you would have to essentially re-kit the K3 to replace it, and then build the radio again. For many of us who built our K3 radios to begin with, it would be a couple day?s work. A lot of folks would have sent their radios back to get it installed, and Elecraft would have spent all their time tearing down and rebuilding k3s(or building a K3 over again from a bag of boards) instead of building K3(s)s .. How the heck do you differentiate between plurals with this radio :-) In any case, I understand (sort-of) why the new main board wasn?t an offered upgrade option. But I?ll still throw in my vote ? be happy to buy one. I guess Elecraft needs to maintain some differentiation between versions.

That is far too simplistic. Anyone's personal definition of "the better synthesizer" will depend on what range of frequency offsets is more important for their particular type of operating. For HF CW in particular, phase noise at small frequency offsets is of paramount importance and I wouldn't argue with Don's report of "a huge improvement in both transmit and receive phase noise" - but *only* in that specific context. There are also several other advantages that are relevant to high-performance HF CW that could also justify upgrading to the KSYN3A. At close frequency offsets from the carrier, the KSYN3A does indeed offer a large reduction in phase noise compared with the KSYN3 (which itself was already good). But at wider frequency offsets, that situation reverses. According to the ARRL review [1], at all offsets beyond about 6kHz, the older KSYN3 continues to have a lower noise floor than the newer KSYN3A "upgrade". Performance at wider frequency offsets, 10-100kHz and beyond, is of much greater importance in VHF-UHF contesting. This due to a combination of factors. The strongest signals at VHF-UHF are often much stronger than on HF, due to the use of high-gain beam antennas; and also the weakest signals are *always* much, much weaker due to the lower levels of natural background noise. These two features stretch the requirement for dynamic range on VHF-UHF far beyond those for which most HF transceivers are designed. Anyone transmitting wideband phase noise has a much greater risk of raising the noise floor of many other stations across the whole contesting segment of the VHF or UHF band. Running the numbers reveals that anyone aiming to be a Big Gun in VHF contests has a responsibility to keep their wideband transmitted noise floor below about -130dBc/Hz at frequency offsets of 50kHz and more [2]. This can be a major engineering challenge, and the performance of the transceiver is almost always the most important building block. The KSYN3A just about meets the -130dBc/Hz noise floor target at frequency offsets of 10kHz or more... but according to the ARRL review [1] the older KSYN3 achieves it much more comfortably, with 10-15dB to spare. I have both a K3S and a very early-model K3. The K3S (with the KSYN3A, of course) is used for HF contesting where smaller frequency offsets are important. Meanwhile the old K3 is now used as a transverter driver for 144MHz and above - and for that particular purpose there are very good reasons *not* to replace the original KSYN3. 73 from Ian GM3SEK [1] http://www.arrl.org/files/file/ProductReviewsForDeb/2015/pr112015.pd f [2] https://thersgb.org/members/publications/video_archive.php?id=5703 Sorry, this talk is accessible only to RSGB members, but in a few words... G8DOH runs the numbers to demonstrate that the -130dBc/Hz target for transmitted phase noise is necessary to avoid raising the noise floor of other stations many kilometres away, and also many tens to hundreds of kHz away across the band, whenever their high-gain beams happen to be pointed at each other. That calculation assumes the UK transmitter power limit of 400W PEP output. For the US power limit of 1500W output, keeping all other assumptions the same, the target for transmitted noise floor would need to be better than -135dBc/Hz. The older KSYN3 can still meet that more stringent target but the KSYN3A probably cannot. >-----Original Message----- >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of Don Wilhelm >Sent: 27 June 2018 14:23 >To: hawley, charles j jr; Charlie T >Cc: elecraft at mailman.qth.net >Subject: Re: [Elecraft] [K3] factory upgrade to K3(s) > >Chuck, > >A big reduction in receiver noise floor and a huge improvement in both >transmit and receive phase noise.

The K3S is more than an upgraded K3 (for example, the RF Board cannot be changed in the K3), but it is similar to the change in the K2 that happened at SN 3000. Hindsight says it should have been called the K4 or something similar. Eric is likely to shut down this thread soon!

I'm certain that some charlatan preying on high futility nuts would be quite happy to lighten his bank account by at least as much as he paid for the KPA500. These products provide no benefit to audio consumers, and they would provide no benefit in a ham station. Their only function is to transfer money from the buyer to the seller. None of what's being discussed here should be a problem, and the easiest ways to minimize the symptoms are 1) to simply beef up the wiring between the power amp and the distro panel, or 2) shorten the wiring, or 3) provide a breaker dedicated to the shack. A single 15A circuit should run all the RADIO equipment in the shack where the power amp is a KPA500. Obviously, a 20A circuit provides more margin, bigger copper and shorter copper reduce IR drop. For the printer, as others have noted, the IR drop between it and the breaker panel for the turn-on surge, so bigger copper for that part of the run would also have to be replaced.

The new synthesizer does not make any difference to the noise floor in the absence of strong nearby signals. This is how noise floor is usually measured. What it does is improving the reciprocal mixing of nearby signals and the phase noise on transmit. This improvement is significant. But the basic sensitivity of the receiver (noise floor) is not affected.

Receive recovery time seems shorter. And I believe they extend receiver usability in VLF from 500 down to 100 Khz or so, for 220M. At the time they became available Elecraft published an FAQ about the new synths, which might still be available online. As for what the old synths can be used for when removed, the best I heard was drink coasters. I tried to give mine away but there were no takers even at zero dollars, shipping prepaid.

The new synthesizer does not make any difference to the noise floor in the absence of strong nearby signals. This is how noise floor is usually measured. What it does is improving the reciprocal mixing of nearby signals and the phase noise on transmit. This improvement is significant. But the basic sensitivity of the receiver (noise floor) is not affected.

It looks like even on 20m they are at their best between midnight and 4am EDT. I have resigned myself to some sleepless nights in order to nail them. For me it's an ATNO. The propagation forecast site linked to on their web site correctly predicted this, but I couldn't quite believe it until I saw the evidence on the spotting cluster this morning. I have worked many of the nearby South Pacific islands in the past but never in the middle of the night.

I just checked it, and the link to http://kh7z.net/ is working here and has the latest info. Updated this morning from that page: --- June 29 1100z Update June 29, 2018 by kc1cwf Good news. All but one station deployed. We are running up to 7 stations on all bands and making many QSOs after a weather related slow start. We hope to provide many ATNOs over the next week. We are now well over 10,000 QSOs, with great rates on CW, slightly slower rates on SSB, and FT8 has been effective. Please make sure to read our primer at baker2018.net on working us on FT8. The bad news is our BGAN terminal system for log uploading refuses to link up with the bird. We have two BGAN terminals on island and neither are correctly connecting to the satalite. We will continue to work to sort this out, but right now we can?t upload logs. The weather continues to be extremely hot and humid. But that is what we expected. Tomorrow we plan on constructing the 6 meter antenna. That?s all for now. Many people to work. --- 73, Eric /elecraft.com/ On 6/29/2018 3:56 AM, James F.

That's not necessarily a bad thing, but if you're looking for "pleasant" sounding audio, the HC4 might not be the best choice.

I realize that Elecraft's position is that VOX is a no-no. However, CAT is a PITA no-no for me, particularly when Microsoft reassigns comports Willy-Nilly. There is a reason for using "real" split and that's to get audio IMD products out of the passband.? Except for chasing the KH1 operation, I've abandoned FT8 and haven't been keeping up, but at one time it was agreed that WSJT-X sends a split command to the K3 at the beginning of each transmission and waits for a response back before actually transmitting.? Hence the delay.? I fail to see how anything done in Task Manager will fix this.? It's a non-issue on receive.

When you transmit the lower audio tones, their harmonics and distortion will still be in your audio passband and be transmitted along with the desired tones. The purpose of using proper rig control is to keep the audio tones above 1500 Hz so the harmonics and distortion are out of your transmit passband. -- 73, Mike Cizek W?VTT -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Rick WA6NHC Sent: Friday, June 29, 2018 14:06 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 and WSJT-X Split operation.

In fact the DATA MODES section of the K3 manual clearly states "You cn use either VOX or PTT." If your audio levels are correct, VOX should be no problem. I personally prefer PTT via CAT command. Now if you are using the K2, then I definitely recommend NOT using VOX because it does not trigger reliably with DATA mode audio. 73, Don W3FPR On 6/29/2018 3:24 PM, Wes Stewart wrote: > I realize that Elecraft's position is that VOX is a no-no.

Message-ID: A few years ago, in a distant land known for its modular seafood delicacies, one of our vendors decided--without informing us--to stop producing a critical item used in the Elecraft K2: the LCD backlight. We got the news when we attempted to re-order early this year. Worse, they could never make them again. Both the dusty scrolls upon which the details were scribed and the monks who toiled in the secret factory had vanished. We would have to reinvent this particular wheel. That task has now been completed; we home-rolled our own backlight from modern materials. We?re pleased to announce that the new green glow is the equal of the old. Thus the K2 is reborn, on approximately the 20th anniversary of its first beta shipments. It?s in stock and ready to exercise kit-building muscles of all ages. Why build a K2? To summarize what our thousands of builders have told us: - it?s fun, and the fun can be shared (with one?s progeny, for example) - educational (you?ll learn a *lot* about how a radio works) - rewarding (it?s still the only high-performance, all-band HF kit radio) Regarding the K2?s performance, you may have read recent enthusiastic Field Day reports from its owners. This is no coincidence. The K2 was bred for success at battery-powered field outings, with both ultra-low current drain (~150 to 200 mA) and high blocking dynamic range (it?s one of very few low-cost transceivers to hit the magical 135 dB level, allowing co-located rigs to play fair). The K2 is also an analog superhet design, with crisp audio and very fast QSK. This is a great time to embark on a K2 adventure, given various specials in honor of summertime and the K2?s reemergence. You can find these specials on our order page (www.elecraft.com/elecraft_prod_list.htm). Or give us a call to talk about which K2 package would best suit your needs. A K2 can be upgraded at any time by installing your choice of several option modules. No particular order is required. The most popular options are the wide-range ATU (KAT2) and SSB module (KSB2). If I?ve left any of the K2?s technical or philosophical mysteries to your imagination, feel free to email me directly. 73, Wayne N6KR From alorona at sbcglobal.net Fri Jun 29 17:47:13 2018 From: alorona at sbcglobal.net (Al Lorona) Date: Fri, 29 Jun 2018 21:47:13 +0000 (UTC) Subject: [Elecraft] [K3] factory upgrade to K3(s) In-Reply-To: <002601d40e60$004a5df0$00df19d0$@co.uk> References: <5B32F062.7050307@verizon.net> <3C14F4C5-B734-4ED6-AAF1-5B8FFFE1D47E@widomaker.com> <001401d40e0c$2fef37f0$8fcda7d0$@erols.com> <715485a9-7326-35eb-d6df-9a30533cb4a9@gmail.com> <003d01d40e16$23dd6bd0$6b984370$@erols.com> <924754C0-76C6-4BF5-8921-E5A70C72BB5C@illinois.edu> <6c584e00-234a-30ec-021c-bc0bd76329a2@embarqmail.com> <002601d40e60$004a5df0$00df19d0$@co.uk> Message-ID: <1478776376.584067.1530308833590@mail.yahoo.com> I'm not sure I agree with the exact numbers, Ian. I'm looking at the review from Nov 2015 QST (from the Product Review archive on www.arrl.org ) and it appears that the difference in phase noise between old and new synths is closer to about 3 dB (difficult to tell from the graph) beginning at offsets of *50 or 100 kHz*, not the 6 kHz you cited. At 6 kHz the new still beats the old by almost 20 dB! So, while the old synthesizer certainly exhibits lower transmitted phase noise out beyond 50 kHz offset, the new one is within a few dB of it, and at 50 MHz both seem to meet the -130 dBc/Hz limit you cited.

That is far too simplistic. Anyone's personal definition of "the better synthesizer" will depend on what range of frequency offsets is more important for their particular type of operating. For HF CW in particular, phase noise at small frequency offsets is of paramount importance and I wouldn't argue with Don's report of "a huge improvement in both transmit and receive phase noise" - but *only* in that specific context. There are also several other advantages that are relevant to high-performance HF CW that could also justify upgrading to the KSYN3A. At close frequency offsets from the carrier, the KSYN3A does indeed offer a large reduction in phase noise compared with the KSYN3 (which itself was already good). But at wider frequency offsets, that situation reverses. According to the ARRL review [1], at all offsets beyond about 6kHz, the older KSYN3 continues to have a lower noise floor than the newer KSYN3A "upgrade". Performance at wider frequency offsets, 10-100kHz and beyond, is of much greater importance in VHF-UHF contesting. This due to a combination of factors. The strongest signals at VHF-UHF are often much stronger than on HF, due to the use of high-gain beam antennas; and also the weakest signals are *always* much, much weaker due to the lower levels of natural background noise. These two features stretch the requirement for dynamic range on VHF-UHF far beyond those for which most HF transceivers are designed. Anyone transmitting wideband phase noise has a much greater risk of raising the noise floor of many other stations across the whole contesting segment of the VHF or UHF band. Running the numbers reveals that anyone aiming to be a Big Gun in VHF contests has a responsibility to keep their wideband transmitted noise floor below about -130dBc/Hz at frequency offsets of 50kHz and more [2]. This can be a major engineering challenge, and the performance of the transceiver is almost always the most important building block. The KSYN3A just about meets the -130dBc/Hz noise floor target at frequency offsets of 10kHz or more... but according to the ARRL review [1] the older KSYN3 achieves it much more comfortably, with 10-15dB to spare. I have both a K3S and a very early-model K3. The K3S (with the KSYN3A, of course) is used for HF contesting where smaller frequency offsets are important. Meanwhile the old K3 is now used as a transverter driver for 144MHz and above - and for that particular purpose there are very good reasons *not* to replace the original KSYN3. 73 from Ian GM3SEK [1] http://www.arrl.org/files/file/ProductReviewsForDeb/2015/pr112015.pd f [2] https://thersgb.org/members/publications/video_archive.php?id=5703 Sorry, this talk is accessible only to RSGB members, but in a few words... G8DOH runs the numbers to demonstrate that the -130dBc/Hz target for transmitted phase noise is necessary to avoid raising the noise floor of other stations many kilometres away, and also many tens to hundreds of kHz away across the band, whenever their high-gain beams happen to be pointed at each other. That calculation assumes the UK transmitter power limit of 400W PEP output. For the US power limit of 1500W output, keeping all other assumptions the same, the target for transmitted noise floor would need to be better than -135dBc/Hz. The older KSYN3 can still meet that more stringent target but the KSYN3A probably cannot. >-----Original Message----- >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of Don Wilhelm >Sent: 27 June 2018 14:23 >To: hawley, charles j jr; Charlie T >Cc: elecraft at mailman.qth.net >Subject: Re: [Elecraft] [K3] factory upgrade to K3(s) > >Chuck, > >A big reduction in receiver noise floor and a huge improvement in both >transmit and receive phase noise.

The first 4 bars are there to assist you in adjusting the audio level. I don't know how many times we have to repeat that, but follow the instructions in the manual. If you need a more complete explanation, go to my website www.w3fpr.com and scroll the left column down to the bottom article - click on the link to get the full information. 73, Don W3FPR On 6/29/2018 8:24 PM, Bob McGraw K4TAX wrote: > If it power hunts, this is a clear indication that the audio level is > not correct.?

Someone may be quoting bad advice, or misunderstanding good advice. :) FWIW, I've NEVER used PTT for any mode to key a radio -- I use it ONLY between radio and power amp. Only VOX works fine for all digital modes, and I also use it for SSB.

To my surprise, the reason for the difference between Al's interpretation and mine is that there are *two different versions* of the ARRL review of the KSYN3A, both available on the arrl.org website. The version retrieved appears to depend on the search route taken. My message posted on Wednesday 27th June was based on the weblink referenced within the message. In that version, Figure 10 shows a very distinct phase noise advantage for the older KSYN3 at wider frequency offsets. However, the version accessed by Al is *different*. In this second version, Figures 10 and 11 both show much lower levels of phase noise from the KSYN3A at wider frequency offsets. (That appears to be the only change, that Figures 10 and 11 have been quietly replaced.) Based on this second version, I would agree with Al that there is no significant difference in phase noise between the KSYN3 and KSYN3A at wider offsets. In view of the uncertainly between the two different sets of published results for wider frequency offsets, it seems best to withdraw my message posted on Wednesday 27th June. Thanks once again to Al W6LX for pointing this out. 73 from Ian GM3SEK >-----Original Message----- >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of Al Lorona >Sent: 29 June 2018 22:47 >To: Ian White; elecraft at mailman.qth.net >Subject: Re: [Elecraft] [K3] factory upgrade to K3(s) > >I'm not sure I agree with the exact numbers, Ian.

I can't believe how much pleasure that piece of equipment has given me. This morning I'll be disconnecting the K2 this morning and heading out to coffee with our little klub in Bigfork, MT. BARK/K7CMT We set up a little ham stick dipole up at 12 feet or so outside the coffee shop and operate CW. Curious customers always are amazed the radio was a kit. The CW ringing out from the speaker sounds so nice it draws people over. We worked ON4UN with 10 watts about 6 months ago from there. It shows how good his antenna's work! I hope every ham on the reflector orders one from you. Long live the K2.

I got my very first amp on Wednesday, a KPA500 and started using it along with the KAT500 I ordered and a K3S I purchased last month. Here is my question: I noticed that when I transmit, the power output varies significantly depending upon how close my mouth is to the Kenwood MC-60 microphone (no batteries in the mic). Is this normal? And how do I make this more consistent? Try to always put my mouth in the same relative position? Buy a different microphone?

The amp and tuner are a great combination. Regarding the mic and varying power, you need to maintain a consistent distance from the mic and a consistent audio level when speaking into the mic or your power will drop off. Watch the mic gain setting, you don?t want it so sensitive that the mic picks up room noise.

Also, you will need to adjust the MIC gain value such that you get 4 to 5 bars on the ALC scale. Yes, mike-to-mouth position is critical.? I'm not familiar with the the MC-60 and its pattern characteristics.? If you like that mike and you get good quality audio reports then I'd say it is OK.?? Personally I use a dynamic mike such as the Shure SM-58 or other like mike.??? With that, the "4 finger" rule, being mouth straight on axis with the mike and 4 fingers distance from the face of the mike I find to produce the best result.?? At the same time, the closer to the face of the mike, the more critical the mike-to-mouth position becomes. ? And if one is too far from the mike, added mike gain is required and the room noise becomes noticeable. Again, mike-to-mouth position and consistency is very important to good quality audio.? Perhaps that is why many use a headphone boom mike.? The mike stays constant with regard to ones mouth as they move around and look at different things in the room. 73 Bob, K4TAX On 6/30/2018 8:29 AM, Michael Gillen via Elecraft wrote: > Hello guys! > > I got my very first amp on Wednesday, a KPA500 and started using it along with the KAT500 I ordered and a K3S I purchased last month. > > Here is my question: I noticed that when I transmit, the power output varies significantly depending upon how close my mouth is to the Kenwood MC-60 microphone (no batteries in the mic).

I have the KXPD3 paddle. I also had the intermittent keying operation with dits and dahs and did the mod to add the small wires to correct it. For the most part, that did fix it. However, recently I?ve noticed that the dah side gets screwy now and then, dit side seems ok. During FD, I had made about 90 contacts, and other then my operator errors, the paddle worked perfectly. I got up to get a drink, hit the head and came back for more operating. The KXPD3 immediately started acting up with incomplete dahs, dit side was just fine. NO one touched it and it only sat idle for 10 minutes or so. I was forced to break out the Bencher BY1 and was able to net another 30 contacts before hanging it up. Bencher worked fine (except for me on occasion). I like the paddle, and really don?t want to drag the much bigger and heavier Bencher around with me on the portable operations. I am at a loss to understand why it could do so well for so long, and then get weird. Any suggestions or ideas? Elecraft? Anyone? Thanks? Jim Leder ?

I was getting no output from the PC to the radio. So thinking that the problem was how I had the internal sound card and WSJT-X set up, I switched back to using my SignaLink, which had worked perfectly before. It worked fine for a while, but then the failed output problem returned. Mysteriously, it would start working again and then after a time fail again. At one point I found that there were two USB Audio Codecs and the standard Realtek driver associated with the speaker settings. I selected the one one not then i use, and the output returned. Then after another failure, I found that there was only one USB Audio Codec associated with the output. This morning I rebooted the computer with nothing connected and found only the Realtek driver. I added the K3S USB cable, and one of the Codecs returned. I added the SignaLink cable, and the second Codec returned. By selecting the correct USB Codec, I was back in business. So somehow the Codec driver for the SignaLink is getting changed or wiped out. I assume that when I used the internal sound card, the wrong Codec was selected. I hope this helps anyone else having similar problems. Any insights on how the CODEC is wiped out would be much appreciated.

I was pleased to see that a recent version of Win4K3 displays the ALC on transmit. I discovered however that the mike gain control in Win4K3 does not control line in when using Data A as it does on the radio but continues to control the mike gain. That is a major problem if you wish to do remote control using a screen mirroring program. I considered writing a macro for this purpose however there does not appear to be any provision for controlling or reporting the line in value in the command set. As a result of the above I have two questions: 1. Is there a method to remotely control the line in value? 2. Does a K3/0 control line in when in Data A and mike gain when in SSB as does the radio?

Unfortunately, these have become unobtainium. The KX2 and KX3 take a different approach. They still have per-band filters with excellent stopband attenuation, but they don?t require tuning. Of course these rigs also cover many more bands (9 and 11 respectively) without the need for modules.

Shift and Width will drive you crazy because each time you reduce the width, you will have to adjust Shift to maintain a good center frequency. HiCut.LoCut adjusts it automatically. Set the low end between 300 and 400 Hz initially, then set the high end initially for 2800 to 2900. If there is QRM on the high frequency side, reduce the HiCut, and if there is QRM on the low frequency side, increase LoCut. You will find that you cannot cut the low frequency end very far before you lose intelligibility, but you can cut the high end significantly. While you will lose the voice characteristics, it will remain intelligible down to 1600 or 1800 Hz. 73, Don W3FPR On 6/30/2018 8:07 PM, Bill wrote: > I recently purchased a K3 and trying to set up for SSB.I do not do code. > Is there any recommended settings for the shift lo cut and width? > It has the KFL3A-400 and the KFL3A-12.8 8 pole filters installed > I have read the manual and it does not really help me.

The K3 is a really nice radio with extraordinary factory support. For SSB, I set low cut to .35 KHz and adjust the upper cut between 1.9 KHz and 2.8 KHz, depending on conditions. Higher makes for easier copy, but lower will eliminate more noise, and help with nearby stations. Remember, the crystal filters are to protect the AtoD converter in the receiver.

Set LoCut for 300Hz and HighCut for 2700Hz initially. That gives you comfortable audio when there is no serious QRM. If QRM from above in frequency bothers you, crank the HiCut down to 2400Hz or even 2100Hz. If you have narrower crystal filters, like 2100Hz or 1800Hz they will switch in automatically. Don't touch the FL button. If you have QRM from below (assuming USB) unfortunately there isn't much you can do. As Don says (in a different thread), cutting the lows much above 300Hz quickly affects intelligibility. Lowering the HiCut also lowers the noise floor of the receiver if you are listening to a signal in the noise.

One question: On my K3S I cannot set the LO CUT to .35KHz it only steps in .10 increments not 0.05 increments is there some CONFIG item I need to change?
