From ebasilier at cox.net Thu Nov 1 00:08:41 2018 From: ebasilier at cox.net (Erik Basilier) Date: Wed, 31 Oct 2018 21:08:41 -0700 Subject: [Elecraft] OT: Surgery on female N-connector Message-ID: <000001d47198$938a2960$ba9e7c20$@cox.net> My apologies for going far OT here. Any replies direct only please. I am trying to fix the broken N connector on a surplus 100W dummy load, RELM T44004. The female part has lost 2 of its 4 fingers, and needs to be replaced. The connector has a standard size square flange with 4 screws. (This is *not* the same as the larger square flange of the interchangeable Bird connectors). On the back is a custom part that connects to the load resistor. It seems to be crimped to the female N part. My hope is that I will be able to separate these parts and attach the custom part to a new N-female part. The combo slides out easily from the teflon insulator. The first task is to obtain a new N-female part, preferably gold-plated. Taking a hacksaw to a barrel female-female, or elbow male-female seems like a lot of work. Even getting the center connector out of a chassis mount N female might take some work, but seems easier. My junk box is heavy with N connectors, but to my surprise I couldn't find a single chassis mount N female. My question to the group: Has anyone attempted to get the center part out from a female N connector? Was a particular brand of N connector especially easy to work on? Thanks in advance for any tips. 73, Erik K7TV From hillslaird at internode.on.net Thu Nov 1 07:02:13 2018 From: hillslaird at internode.on.net (Kev Schache) Date: Thu, 1 Nov 2018 21:32:13 +1030 Subject: [Elecraft] KX3 -Win4K3 Suite - external Soundcard Message-ID: <20a3a2c3-2f48-80c4-9201-3c4ccc99d501@internode.on.net> Greetings from South Australia to all, I'm an octogenarian ham, first licensed in 1960,? the very proud owner- builder of a K2 and more recently a KX3, extremely happy with Elecraft and both radios..

But, you can check on all of the potential cards on the Telepost web site. You can Google NaP3 and find the url that way. I use Win4K3 with both my KX3 and K3s with a Steinberg UR22. It works great. The point being that there are more than one card that will work fine if you need to buy a card. 73, Barry K3NDM ------ Original Message ------ From: "Kev Schache" To: Elecraft at mailman.qth.net Sent: 11/1/2018 7:02:13 AM Subject: [Elecraft] KX3 -Win4K3 Suite - external Soundcard >Greetings from South Australia to all, > >I'm an octogenarian ham, first licensed in 1960, the very proud owner- >builder of a K2 and more recently a KX3, extremely happy with Elecraft >and both radios.. > >I'm looking at the Win4K3 Suite with a view to using it with the KX3 >and my Windows 10 Notebook to get some form of pan-adapter, the PX3 >being out of my reach financially.

The rig goes into transmit but there is no RF output. I also tried other digital modes that have worked previously (Digipan and FLdigi) with no luck. I checked my mechanical connections, cables and K3 settings (LINE=35, MIC SEL=LINE IN) and all seems OK. I'm using WSJT-X version 1.9.1. My fundamental question is where to start on debugging a LINE IN problem? I should mention that the rig interface is a microHAM microKEYER (worked Z23MD on FSK so that part works).

I lose nothing and eliminate that lightning path. As to the cable itself coming to the house, I have replaced the cable company's grounded F81 Barrel Connector between the drop line and the house with a 75 ohm grounded surge protector bought at DXEngineering, I use them on my two HI-Z RX arrays as well. After taking a hit to my just out of warranty, McIntosh tube preamp's USB this year, (forcing me to either pay big $ in repair or go with Toslink, I chose the glass toslink. (For audio only, the Toslink is excellent but with this system Toslink only offers one way communication from the computer to the preamp and some home entertainment utilizes two way communication). Fortunately, my needs don't require this. Those 75 ohm cable lines must be protected, just like our communications coax. 73, Gary KA1J > very good suggestions Wayne.

I am about to get a KAT-500 to mate to my IC-7300. In searching for the Molex connector I need to make an interface cable for the radio to the tuner, I came across the MFJ-5124I cable which MFJ sells to mate their 99* series auto-tuners to Icom radios. The connectors on the tuner end are the same as used on the KAT-500. The wiring is the same with one addition. Where there is no ground connection from the sleeve of the 3.5MM stereo plug specified in the KAT-500 manual, the MFJ cable has the sleeve connected to the ground pin of the Icom connector. Seeing the that the sleeve of the 3.5mm stereo connector on the KAT-500 is chassis grounded anyway I think I can use the MFJ cable to interface my KAT-500 to my IC-7300. Does anyone see the flaw in my thinking?

It was the worst antenna I have ever tried to listen on. The dry reeds below rustling in the wind caused so much static that the noise level from it was more than all but a handful of local signals. Took me weeks to install and fight through the jungle of reeds and I ended up taking them down after a couple weeks of frustration. I worked no DX with those Beverages.

Message-ID: <5BDC89FA.10899.88F41E@Gary.ka1j.com> I seem to have an issue with the K3 memory settings for the microphone. I changed the TX EQ to match settings and now when I check, the TX EQ is back to flat again. This has been happening since I set the values. I've had to restore the values I know them by heart and can do it quickly. Still, I don't know when they get lost so I always have to keep checking to be sure they are still active. Just now, when I checked the different modes I find AM mic settings modified in the TX EQ but not with the same values as I used. I set the TX EQ for use with SSB and the MH4, I only found the AM settings were other than "0" when listening to some power line RFI on AM & that AM setting was still on when I happened to check the TX EQ settings. All the other mic settings for SSB were back to default 0. Having had to reset the mic settings frequently, last night I made the settings, turned off the K3, restarted & the settings were still intact. This next day, they are now lost again. To make the settings I enter the main config. Tap the needed # to get each individual audio band, I use VFO A to select the desired value, tap config when done to exit and that's all I do. What am I missing to save this to the K3's non-volatile memory?

I do use Win4K3, I need it to use WSJT as WSJT doesn't like to share ports. I used to use LP-Bridge which let me simultaneously run all my software flawlessly, till WSJT... and I fast discovered it would not play nice unless WSJT had sole communication with my K3/K3s. With Win4K3 I can use all the software simultaneously including WSJT, logging program, N1MM & MMTTY without having to shut all the other software down every time I want to change modes or software. If it wasn't for WSJT making this issue, it would be simple to just keep doing what I was doing with LP-Bridge. As I do use MSK144 & some FT8 and want to keep my logging program running, I need to keep using Win4K3. Tom wrote a clever bit of software, perhaps there is a way to tell it not to change EQ settings, I'll have to check that too.

The drivers in my Yamaha CM-500 are not and they cause problems with the telecoils (magnetic pickups) in my Kirkland Signature 7.0 hearing aids. When running more than 100 watts on 80 or 40 the RF causes the hearing aids to switch modes randomly when the telecoils are activated by a nearby magnetic field. None of my other headphones (Bose & Koss) cause this problem when used with the hearing aids, K3S and KPA500. I could not find this information on either the Heil or Elecraft site.

The answer is yes: All functions of the KAT500 can be conveniently controlled via our KAT500 Utility program, which runs on any PC. Alternatively, you could write your own controller application using the KAT500's simple 2-letter command set. The tuner would have to be housed in a weather-proof enclosure of your own choice.

As soon as I put on the CM-500s the aids switch to magnetic input and work well until the RF is present. The question was about the shielding in the Heil headset and not how to mitigate the RF. The levels are certainly high. I have learned that the Heil speaker elements are not shielded so I will not try them.

On the base K2, do check the voltage at the left end of R30 to make sure it is between 1.0 volts and 7.0 volts (1.5 to 6.5 volts is better) at the low frequency and high frequency ends of your preferred frequencies on 60 meters. You may have to adjust L30. If you do, then you should check the R30 voltages at the end points of all other bands to make sure they are all within range. That is mentioned in the K60XV instructions. You may also have to re-peak the 40 meter bandpass inductors and then peak the trimmer capacitors on the 60 meter board. Other than those alignments, no other ones are necessary. 73, Don W3FPR On 11/3/2018 10:20 AM, Martin wrote: > Elecrafters, > i'm in the process of installing the 60m module.

Certainly, the operator could always put the amplifier into standby when the KAT500 needs to tune, that reduces the seamless operation of the KAT500. 73, Don W3FPR On 11/2/2018 5:54 PM, Wayne Burdick wrote: > Someone asked me recently whether a KAT500 could be remote-controlled and placed closer to the antenna(s).

If it is on the K2, open the top (or remove the KPA100) and check the position of the switch or jumper on the top of the Control Board slightly to the right if center. The switch should be positioned toward the center of the K2 or if a jumper, the jumper should be on the 2 header pins closest to the center. Lo Batt can also be caused by a faulty power supply connection, power supply connections that are not tight. If you assembled APP connectors, make certain the contact blades are fully inserted. If you look in at the end of the connector and can see the tip of the spring as well as the tip of the contact blade, it is not properly assembled - push the contact blade and wire in more until you hear the spring blade click into place. Make certain your power supply is 13.8 volts to 14.3 (or even 14.6) volts. 73, Don W3FPR On 11/3/2018 2:12 PM, Mpridesti via Elecraft wrote: > Just hours before a contest now get a ?battery low? indication > From donwilh at embarqmail.com Sat Nov 3 14:50:29 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 3 Nov 2018 14:50:29 -0400 Subject: [Elecraft] Dual Ptt In-Reply-To: <758654889.509517.1541269271174@connect.xfinity.com> References: <758654889.509517.1541269271174@connect.xfinity.com> Message-ID: Ralph, If you must switch between the two rigs, you will need to connect the K3 for basic mode - only the KEYOUT line and not AUX cables. Although you might derive a diode "OR" circuit, I assume you will also need to switch the RF path - so I suggest that a hard contact switch or relay will be more trouble free and more free of operator errors caused by keying the amp and ATU from the wrong transceiver. You may also want to switch the microphone/PTT and/or paddles from one transceiver to another. Easily done with a switch or relay. I strongly believe in the KISS principle. 73, Don W3FPR On 11/3/2018 2:21 PM, Ralph S.

This cannot be determined anywhere but in the ATU, thus it must provide the break. That key line break is pretty important to the life of the ATU." Thanks to Jack and Dick for pointing out the flaw in my proposal. However, I still don't know of any other remote tuner than provides an amplifier keying interrupt. Are there any? If not, how do those QRO remote tuners survive? Wouldn't it be possible for KAT500 firmware to inhibit tuning when the input power exceeded a safe level? Isn't that protection included now? It would seem to be a requirement very similar to maximum power for key line interrupt - "When your KAT500 starts to tune, because of a band or antenna switch, a TUNE button press, or auto tune based on VSWR threshold, it waits for the transmit power to drop below this "Amplifier Key Interrupt Power", then it interrupts the amplifier key line, waits for a tune-level signal from the transceiver, and selects the appropriate relay settings.

But then it won?t tune and the cores will overheat from excess power trying to use a now-invalid solution. You must disable the amplifier to perform a tune or anytime the ATU needs to do any switching. It determines when it needs to do that (say from a QSY where it needs to go to a different solution). If you have fixed-frequency operation and can guarantee that the ATU won?t need to change the relays while power is high, then your analysis may be correct. Why risk it? So what is wrong with hot switching? You get arcs across the relay contacts greatly reducing their lives. Having to replace the relays isn?t fun, but having to replace a coil because the relay won?t make contact is even worse. There is a reason we designed the key line interrupt into the ATUs.

The main difference with version 1.0x firmware is that CAL PLL must be done on each band with the earlier firmware, and with version 2.01 and above it is run only on 40 meters. It sounds like your filters need to be aligned and the frequency display calibrated. You can start with the K2 Dial Calibration article on my website www.w3fpr.com. Detail of using Spectrogram for setting the filters can be found on Tom Hammond N0SS (SK) website which has been preserved by the mid-Missouri Amateur Radio Club and can be found at http://www.mmccs.com/mmarc/n0ss/ - scroll down to Elecraft K2 Related Files, and on that page Scroll down to the Spectrogram document. Do not use Tom's link to find Spectrogram. I have preserved a copy of both version 5.17 and version 16 (both freeware) on my website. Scroll to near the bottom of the home page to find the links. 73, Don W3FPR On 11/4/2018 9:40 AM, Martin wrote: > Elecrafters, > i successfully installed the 60m-Module, i have rx and tx. > The qso-partners tell me my modulation is very high pitched and > therefore almost unreadable.

But then it won?t tune and the cores will overheat from excess power trying to use a now-invalid solution. You must disable the amplifier to perform a tune or anytime the ATU needs to do any switching. It determines when it needs to do that (say from a QSY where it needs to go to a different solution). If you have fixed-frequency operation and can guarantee that the ATU won?t need to change the relays while power is high, then your analysis may be correct. Why risk it? So what is wrong with hot switching? You get arcs across the relay contacts greatly reducing their lives. Having to replace the relays isn?t fun, but having to replace a coil because the relay won?t make contact is even worse. There is a reason we designed the key line interrupt into the ATUs.

It is a remote tuner but not automatic. For a variety of reasons I have it sitting under a "Fake" rock that I got at a big box home improvement center. I think it cost about $28 and protects the tuner from UV and lots of other stuff... PLUS my XYL thinks it looks great compared to the tuner box sitting there. I also have a smaller fake rock over the conduit where it comes up by the tower base... a couple of real rocks (small boulders) helps 'balance' the look at the base of the antenna. If I recall correctly, AB2TC remotely controls his KAT500. He may weigh in on this discussion. What I recall of his setup is well thought out.

Then I got KXPA100 and forgot about HLA300. 73, Igor UA9CDC 05.11.2018 19:49, Petr, OK1RP/M0SIS ?????: > Hi all, > > I would like to ask if someone is tested or even using some 100W-150W > non-Elecraft booster for KX3? > > I am looking for something cheap but reliable and found this small toy: > http://www.rmitaly.us/index.php?main_page=product_info&products_id=128 > > The big disadvantage is that T/R switching is RF VOX by relays (no QSK > available on CW) > and second complain lack of output band-pass filters bank. > > Is there someone who has an experiences with that small amp from RM Italy > please? > (I do not want to remove my KPA500 from the rack...) > Any hints or tips are appreciated. > > > > ----- > 73 - Petr, OK1RP > "Apple & Elecraft freak" > B:http://ok1rp.blogspot.com > G+:http://goo.gl/w3u2s9 > G+: http://goo.gl/gP99xq > -- > Sent from: http://elecraft.365791.n2.nabble.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 ua9cdc at gmail.com > From rmcgraw at blomand.net Mon Nov 5 15:30:49 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 5 Nov 2018 14:30:49 -0600 Subject: [Elecraft] Dual Ptt In-Reply-To: <758654889.509517.1541269271174@connect.xfinity.com> References: <758654889.509517.1541269271174@connect.xfinity.com> Message-ID: I basically do the same with different radios.??

That's why it's cheap -- a lot of the parts are missing. It's quite normal for power amps to generate strong harmonics -- 5dB down is common for the second harmonic -- so they must be filtered by an output network. Solid state amps without tuners have networks that match to 50 ohms.

The only caution I can give of with a configuration like that is for the operator who uses voice modes with VOX turned on. Most ham mics are wired for VOX operation - in other words, the mics are 'live'. For those who use speakers too, the mic on the 'not in use' can pick up the sound from the 'live' transceiver speaker and set it in transmit mode. The use of headphones will likely cause no problems, but the combination of VOX ON with speakers live can cause a problem for voice modes. My preference is for hard switching to eliminate a lot of "strange happenings" - besides, I like to feel I am in control of such things. Such a switching arrangement can be easily built, but there are several SO2R boxes that will accomplish the same thing. 73, Don W3FPR On 11/5/2018 3:30 PM, Bob McGraw K4TAX wrote: > I basically do the same with different radios.??

I think it give a bit more protection from "tired operator syndrome".

K3 - Resolved Message-ID: <5BE1CC44.9816.1513A883@Gary.ka1j.com> Folks, FYI, there is a resolution to the issue. A history in short: I started having issues of localized frequency changes. I discovered REF CAL would only lock on a 10MHz source if the source was cold and then only after I rebooted the K3. I tried two different sources with the same exact results. Once it locked on, I could not engage XREF OUT, when I left REF CAL and returned to it, the asterisk was solid, not flashing. Rebooting with a cold 10MHz source was the only way to get a lock. After exchanging emails with support it at first appeared to be an issue with the K3EXREF board or connections but with the numerical value displayed in REF CAL, it was lower than expected and Elecraft support felt the TXCO in the K3 was suspect. With that, I had my old TXCO from when I exchanged it with the .1 TXCO, I replaced the failed .1 and WooHah, there is the always reliable K3 operating exactly as it should. Lock with REF CAL is working perfectly, the frequency is stable and it works fine with both 10MHz sources. This revelation coming last night, it's too soon to tell but I think I am seeing less artifacts that looked like constant vertical lines with regular horizontal lines in the waterfall on the P3 SVGA. This was only at certain times and worse on specific frequencies. Perhaps some of the stuff I've been trying to track down and failing to do so is because of this failing TXCO? Maybe someone with this future issue will find this thread and it'll help them, it's been a real work maker for me. 73, Gary KA1J > Ed, > > Thanks for the reply. I do need an > oscilloscope.

Those amps were marginal at best, although if you ran them well below their rated output they weren?t ?too dirty?! Hi. RM Italy also sold a line of amps that didn?t even have proper bandpass filtering as they were intended primarily for CB. I think those just had an ?HL? designation. These newer models supposedly are a much better design. I first saw them at Dayton a couple of years ago. The price went up substantially too! Supposedly these are all FCC certified, whereas the prior models were not.

One vendor who does have photos of some reproduction knobs for Philco sets on his website: http://www.renovatedradios.com/productlist.php A couple of additional possibilities who have lots of knobs for sale at vintage radio swap meets: Mark Oppat at http://www.oldradioparts.net/knobs.html And Jim Sargent (who runs an auction house as well as selling old radio parts) at http://www.sargentauction.com She?d likely need to send the radio?s model number and/or a photo directly to these resources to assist in tracking down the needed knob. The good news is that members of the antique radio community are generally great at helping folks looking to locate a needed component, and Philco sets were among the most common radios sold through the 1930s and 40s making parts more available . . . 73, Neil WA7VHT On Nov 6, 2018, at 3:45 PM, Dauer, Edward > wrote: I attended a performance today by a woman who does a Rosie the Riveter routine as if she is speaking from 1944, dramatizing principally the roles of women during WWII.

The FCC now allows companies to perform "self certification".?? In other words, they allow the fox to watch the hen house.??? The companies can elect to do the testing and submit the results to the FCC. Thus the FCC does not actually test products to issue the certification.?? I personally find many items, such as, power supplies, CFL lamps, routers, printer power supplies, and a host of other items that are producing noise and these do have the required Part 15 along with other certification labels. I did work for a company whose products were required to be "certified" by several safety organizations and to meet radiation and safety standards.? We used an independent testing company for all of these tests. ? ? On more than one occasion I observed a product just barely meet or just barely? exceed the required radiation levels.?? The company said "this is close enough we can pass it".?? I said NOPE, it has to go back to Engineering to be improved.? Well need less to say that caused turmoil with Sales, Marketing, Engineering and Management.??? But I stood my ground and said "improve it" knowing that production units might be worse in terms of emissions.?? Many companies seem to take the approach "we saw it work once and it almost meets specs........ship it". Further we find that production changes through the life of a product may be related to part and design changes.?? No further testing is required as the model number does not change.?? The labels are affixed and the items shipped.? Who knows if they meet the required safety and emissions requirements??? Just because it has the required labels and statements is no assurance that it meets those requirements.?? It is called "economics". 73 Bob, K4TAX On 11/6/2018 2:25 PM, dyarnes wrote: > John and All, > > I?m not necessarily recommending these amps, but you may possibly be confusing them with a prior model line-- The original ?HLA? series, such as the HLA 150 and HLA 300.

The K2VCOSHLDKT will eliminate it, as will a DC fan. The DC fan may have a magnetic field, but it would be constant instead of alternating polarity 120 times a second. 73, Don W3FPR On 11/7/2018 7:50 AM, Steve Kavanagh via Elecraft wrote: > I was experimenting with an external 120V AC fan to improve the cooling of the KPA100 during CW Sweepstakes this past weekend.

I've got one of those insanely oversize LG OLED TVs and it puts out zero RFI that I can see on the P3. I did a lot of testing during the free return period just to be sure I wasn't bringing a noise generator into the house, and it's excellent in all ways. Also, it uses so little power compared to a much smaller Vizio TV, The glass is cool to the touch and the processor compartment is slightly warm at most. OLED can produce a lot of brightness and power consumption relates to brightness so how you set it up matters energy-wise, but your Plasmas are multiples of the power the OLED uses. One very nice thing with OLED is you see genuine black, no backlit shade of gray, it takes awhile to get used to seeing very accurate color and shading when watching in a darkened room, we don't see that with the other kinds of TV. 73, Gary KA1J > We?ve got three plasma TVs in our home.

That's a very convenient way to do it, but connecting the radio directly to PA KEY on the KPA500 bypasses an important safety feature of the KAT500, which is designed to OPEN the PA KEY line while it is tuning. So I'd recommend connecting the other radio's Amp Key output to the PTT RLY (in) connector of the KAT500, and the PTT RLY (out) of the KAT500 to the KPA500 PA KEY. This places the KAT500 in SERIES between the transceiver's KEY OUT and the KPA500's KEY IN. This is well documented in Figures 2, 3, and 4 in the KAT500 Owner's Manual . 73, Bob, N6TV From pincon at erols.com Wed Nov 7 18:02:56 2018 From: pincon at erols.com (Charlie T) Date: Wed, 7 Nov 2018 18:02:56 -0500 Subject: [Elecraft] OT: TV RFI Question In-Reply-To: <166ef8b1c46-1ec0-1a1a@webjas-vae014.srv.aolmail.net> References: <5BE33136.16170.1A85EC37@Gary.ka1j.com> <166ef8b1c46-1ec0-1a1a@webjas-vae014.srv.aolmail.net> Message-ID: <006601d476ee$08ede750$1ac9b5f0$@erols.com> Do they even still sell Plasma TV's?

On page 42 of the KX3 manual, there is a reference to the BND END message that is supposed to appear if I transmit out of the ham band in my radio, however it puts out full power in CW mode (using a dummy load) at 2.5 MHz for example with no displayed message.

(You can also consider them as stepper motors, operating at maximum slew rate.) That's what "brushless DC motor really means". I'd expect to see an AC field, although at a multiple of the rotation rate, and with quite small gaps between stator poles, so with the 1/3 power near field fall off, quite weak at distances.

It is rugged, high performance, fully integrated with the KX3, and very reliable. With PIN diode T/R switching and a fanless design (very large heat sink), it's like having a 100 watt KX3. Also makes a great mobile amp, with fittings for trunk or under-seat mounting on both sides. There are obviously cheaper amps on the market, but they all have compromises compared to the KXPA100. It takes a lot of parts and a solid design to do this job correctly. 73, Wayne N6KR > On Nov 8, 2018, at 5:50 AM, Petr, OK1RP/M0SIS wrote: > > Gordon, > > many thanks. > I know about it but it is 50W only.

Activate the feature from the front panel of the K3S.??? The input impedance of the RSP-1? SDR is well above 50 ohms and thus I didn't observe any loading or loss of the received signal. As to software, HDSDR was my favorite and easy to setup and use. I added OmniRig to allow for full interface to the K3S.? This provides two way communications between the radio and computer. Thus any change on the radio is effected the same on the computer and any change on the computer is resolved on the radio.? Of course there is capability in the HDSDR software to have your choice of the radio following the computer or the computer following the radio or neither, thus both being independent. An excellent and economical approach which I used several years and with different radios as well.?? That is......until I purchased a P3 to go with my K3S. 73 Bob, K4TAX On 11/8/2018 9:19 AM, John Simmons wrote: > Isaac, > > I did exactly that, using the HDSDR software.

This kit was a rev C, and I have brought it up to the latest specs. U1 says PA 1.1. #1: It has passed all of the tests, except it apparently has no low fan speed. I have set the temperature of the heat sink using CAL tPA, after measuring it with an IR thermometer, and I have set and re-set the fan parameters in the secondary menu. On "nor" and on "LoHi" the fan is off. On "Hi" it runs. I have tested the amp's output into my power meter at 100w, but I haven't transmitted long enough to really heat anything up. When I first applied power to the KPA100 for the initial tests, I believe the fan ran at low speed, so I have probably broken something... #2: When I key the amp at 100w, through the power meter, and into a dummy load, I measure about .055v across R7, so that's ~11A. I expected higher current. Does that seem about right? Any insight would be appreciated.

Your audio level should be adjusted to produce 4 bars solid on the K3 ALC meter with the 5th bar flashing.

Has the bias been set correctly for a 400mA rise in PA current with no RF input? That bias setting will alter the operating class of the amplifier and it must be correct to be linear. 73, Don W3FPR On 11/9/2018 11:46 AM, Jim KO5V wrote: > Well, after checking that all of the components in the fan circuit were correct, I decided to follow Don's usual advice about checking my soldering, so I re-flowed all of their joints.

I used a known good DVM to measure the voltage across R7, and it agrees with old Beckman. I now think my old kit-built Ten Tec power meter may be badly out of calibration. I have a dead LP-100 that is on its way back to Larry for upgrade and calibration, so I'll just wait until it is back to finish calibrating the KPA's power setting. Here are what I measured and calculated at the approximate center of each band, in cw, when the K2's LCD read 100W: 10M: .067V, 13.4A 12M: .049V, 9.8A 15M: .064V, 12.8A 17M: .065V, 13A 20M: .048V, 9.6A 30M: .056V, 11.2A 40M: .052V, 10.4A 60M: .056V, 11.2A 80M: .054V, 10.8A The current seems to vary significantly between bands, but maybe that's normal?

My amp is #172 and has been in service since May 2018. It has been super and haven?t had any problems until yesterday. Was on a 160m net, checked in without issue. When my turn happen I keyed the mic and immediately got a fault. Reduced power and checked out. The amp will now only produce about 400-500 watts but the audio is not good per on air reports. Elecraft has my config file and fault table and I?m sitting waiting to see the next steps. This is my first major issue with Elecraft and I hope all goes well. Will keep the group updated. I?m sure glad I kept the the KPA500 and KAT500. That equipment has been in service a couple of years without any problems. Hope it didn?t catch anything from it?s big brother LOL.

Interestingly, even at idle, a switcher is a little less efficient than at full load, so it still needs some cooling air flow. We design all of our product cooling on a very conservative basis. There is a chance we over did this and can slow down the the 1500's PS fans a bit - I'll report back here after we do some further temperature testing. I don't understand the comment about the PS fans getting quieter when the supply is under load in TX. They always run at the same speed. Is there something else I'm missing? 73, Eric /elecraft.com/ On 11/9/2018 2:52 PM, Richard Thorne wrote: > As soon as the supply has a load on it a good bit of the noise is reduced. > > Maybe there's a way to put a small constant load on the supply? > > Rich - N5ZC > > On 11/8/2018 6:59 AM, eric norris via Elecraft wrote: >> Why is the KPA1500 PS fan making so much noise when the amp is in STBY and >> just the ATU is being used?

The Transmit RF Gain varies from band to band, and that will cause the current draw to vary.? I am surprised that 12M is so low, it is normally on a par with 10 meters. Part of the RF Gain variation is in the base K2 and some more of it is in the KPA100. Remember that those are steady state current draws.? The dynamic current such as with SSB operation may peak at greater than what you measured. Yes, use the LP-100 for calibrating the KPA100 wattmeter.? Since the LP-100 has NIST traceable calibration, I would believe it over the readings on a calibrated BIRD. 73, Don W3FPR On 11/9/2018 5:56 PM, Jim KO5V wrote: > Don and Bob, > > The K2 and amp are both powered from the amp's supply. > > I used a known good DVM to measure the voltage across R7, and it agrees with old Beckman.

Oh yes, you have to initially identify the Spam, but the filter learns what is spam and what is not and automatically directs it to the Junk folder. The Embarq (CenturyLink) "reject everything" is IMHO the worst solution to Spam - it not only requires the respondent to go to extra steps saying you are genuine, but requires those using it to respond as well. I know Thunderbird has the Bayesian spam filter built in, and yes, I identify anything that comes into my email with no reasonable content in the text body as Junk Mail. I do not count how many I receive, and I do not click on links that have no associated valid text telling me why I should click on it. Just my opinion. 73, Don W3FPR On 11/9/2018 6:56 PM, W0FK wrote: > Geez guys, I have a spam filter.

I get the inundation by spam situation. I utilize 17 email addresses to separate personal, hobbies, lists (like this one), public facing (club contact) and one used just for bingo card registrations. The club related email gets about a thousand spam emails a day, but most go directly to the junk folder. Unfortunately, so do legitimate ones on occasion. Some of the email accounts never receive a spam message and others get bushel baskets full.

The IT department decided to install filters that would block both incoming and outgoing e-mail that contained offensive language. So they made up a dirty words list, not telling any of the clients what was on it or even that it existed.

For the past 15 years or more, spam filtering has been an arms race. Spammers automiatically open a bunch of email accounts on a free provider, then have scripts try different variations until something would get through. Then they hammer the service with that spam until it was blocked. Then try again. Spam can evolve hour-by-hour to find weaknesses in the algorithms. Similar stuff happens with spiders for web search engines. I?m glad to not be in that business any more. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 10, 2018, at 11:26 AM, Dauer, Edward wrote: > > Before the authorities close this useful but somewhat-OT thread, I would share one anecdote told to me to be true, though I can't personally vouch for it, about an unnamed university twenty-plus years ago.

This is an opportunity to exercise, share and exhibit your personalized fist. This is NOT a contest. However, there is a very easy and quick requested signup form that can be found at https://w6sfm.com/bug-roundup/. Once you have read the page, and optionally registered for the event simply Call "CQ BR" so folks know you are a Bug Roundup Participant.? So lets grab that*bug*, clean those contacts, and let?er fly! We want to hear that ?Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist. *Reserve the date!*The event begins on Saturday November 17th (00:00 UTC) and concludes Sunday Nov. 19th (23:59 UTC), 2018 That's 4:00 PM Friday (Nov. 16th) afternoon until? 3:59 PM Pacific Time Sunday (Nov. 19th LOCAL Time). For more information, to register your station, and to help assist in spotting, potentially increasing QSOs, an*On-line chat window*link can be found near the bottom of Bug Roundup home page located at https://w6sfm.com/bug-roundup/ We hope to hear you all on the air! 73, W6SFM -- W6SFM www.w6sfm.com From eric at elecraft.com Sat Nov 10 20:46:27 2018 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Sat, 10 Nov 2018 17:46:27 -0800 Subject: [Elecraft] Spam filtering In-Reply-To: References: Message-ID: <0D5DD02B-80CF-4333-8381-80519C41A2BB@elecraft.com> Thread now closed (including related SPAM discussion threads. :-) 73, Eric Mooderator elecraft.com _..._ > On Nov 10, 2018, at 11:26 AM, Dauer, Edward wrote: > > Before the authorities close this useful but somewhat-OT thread, I would share one ...

Instead of keeping the local times and changing the UTC numbers I am staying with the Universal time and changing the local.? For me that works out to 2 and 4 PM.? 4 PM should give us enough time to run the 40 meter net before dark.? If those times don't work we'll have to try something else.? From what I heard there was a measure on the California ballot to eliminate changing the clock twice a year. Folks in Oregon and Washington are waiting on those results.?

I acquired it a year ago from another amateur. He demonstrated it for me and I saw that it worked. I have not used it since then. Included: - Elecraft K2/100 HF Transceiver with 100W amplifier and RS232 I/O module - K2DSP internal DSP filter and real-time clock - KSB2 SSB adapter - KNB2 noise blanker - K60XV 60m and transverter adapter - K160RX 160M module - External KAT100 automatic antenna tuner It's in good condition and everything works. However, as I said I never sat down and used it. Instead, I retired and moved to Thailand where I now live. I wanted a K2 because it's on the Thai government's short list of type approved transceivers, i.e., it doesn't cover 6m or 70cm, which aren't currently legal bands here). Once I arrived I discovered that I can't ever get a Thai ham license because Canada doesn't have a reciprocal licensing agreement with Thailand. So the K2 is of no further use to me. The equipment is still in Canada. My friend VE3EG, Keith is handling the sale and shipping on my behalf. You can direct questions to me, but I will turn things over to Keith once we have ourselves a deal. Price for the package is Cdn $1,400 (about U.S. $1,060 at current exchange rates). Shipping is extra and is based shipping from Toronto to your QTH. Many thanks and 73!

Weird first time that?s happened. Closed the links and sure enough it tuned up for 40 fine. So I suspected the antenna is fine. Got home and connected the KX2 to a dummy load and it will tune on every band except 20. Maybe something has come adrift inside, I?m not sure.

The display will show you what is in the K3 IF. If instead you are using it as a sub-receiver, you would connect it to the K3 RX IN and OUT, or use a separate RX antenna on SDRplay.

On a TS-590S TX inhibit is menu 60. The EX command is used to change menu settings over CAT. For a TS-590S - EX06000000; reads the inhibit status EX060000001; sets TX inhibit EX060000000; clears TX inhibit For a TS-590SG the menu number is 66 so substitute 060 with 066 in the commands above. Note that, like almost all menu selections, the inhibit will only apply to the menu (A or B) in which it was set. To be safe it should be applied to both menus.

At least the Elecraft menu items are spelled out in abbreviated English and not a string of numbers. For instance the TX INH menu is not menu #60, but is labeled TX INH in the VFO B display. It is easy to scroll through the menu items to select the one of interest. VFO A changes the parameter in plain language as well. Normally no need to refer to the manual unless the operation of the menu item is in question. 73, Don W3FPR On 11/13/2018 9:33 PM, ANDY DURBIN wrote: > "How does one implement TX Inhibit on a Kenwood TS-590?" > > > On a TS-590S TX inhibit is menu 60.

I don?t see how that is really useful for SO2R where you need pretty much instant switching, but then I doubt that is its use on the Kenwood. That leads to the question of how the TS590S is protected in an SO2R or similar multi-tx environment. 73!

Depending on your software, you can use the SDRplay as a panadapter using either IF or RF (RX Ant In/Out). I use my SDRplay both ways. The software has to be told which connection you are using in order to label frequencies correctly in the display, but they both work and produce similar displays. Likewise, you can use the SDRplay as a second (or third) receiver using either feed method. Again, the SDR software has to know which connection you are using in order to know what frequency to demodulate the audio from, but there is software that will work either way. One caveat with using an SDR using a separate RX antenna: you may need some way to isolate the SDR from the antenna while you are transmitting, such as an external TX/RX switch, or some kind of receiver protection circuit; otherwise, the voltages induced on the receive antenna by your nearby transmitted signal may be high enough to damage the SDR. That is not an issue using either the RX Ant In/Out loop or the IF output from the K3; the RX Ant loop is behind the K3's TX/RX switch (the isolation is not perfect, but it is good enough to protect the SDR), and the IF Out level during transmit is also too low to be a problem. 73, Rich VE3KI W3FPR wrote: Your subject line indicates that you are using SDRPlay as a panadapter, and in that case, you would want to connect it to the K3 IF OUT and tune it to the K3 1st IF of 8.215 MHz. The display will show you what is in the K3 IF. If instead you are using it as a sub-receiver, you would connect it to the K3 RX IN and OUT, or use a separate RX antenna on SDRplay.

So for instance if you want to monitor 15 meters while listening to 40 meters, the signals will be greatly attenuated. There will be no attenuation if you are listening to a band below the frequency the K3 is tuned to. There are compromises to every solution - rule of life as well as radios. 73, Don W3FPR On 11/13/2018 11:39 PM, Richard Ferch wrote: > Actually, Don, that is not the case.

The same is true for Yaesu and Icom transceivers. Now if the radio does this itself behind the scenes, that is another story.

I operate almost exclusively on CW with a KX3 and K2 that I built in 2004. I have the audio from two computers and both radios run to a small Xenyx 502 mixer , then to a small stereo amp and a nice pair of speakers. I seldom use the speakers and I run a couple of pairs of corded headphones from the mixer. I often run afoul of the headphone cord. It gets tangled in the arm of my chair, etc... I would love to have wireless, noise cancelling headphones. However, this would involve putting a bluetooth (or other wireless) transmitter on the mixer output, compatible with whichever model of headphones I buy. The big issue (as far as I can understand it) is Latency. The CW sidetone must not be delayed. I have googled latency specs and found some pretty good data for headphones. I found at least one pair of headphones that measures 40ms latency, a number that would probably work. However, that doesn't include the latency induced by the transmitter. Is anyone using a transmitter/headphone combination for CW that works? If so, please share your setup details. Thanks.

That usually adds a couple of weeks to the repair queue.? (We can easily determine where the lightning activity is around the country from the return addresses..) Don't forget to disconnect ALL cables from your radios, amps etc when lightning is near. We frequently see damage when the cables between the radio and computer are left connected. Nearby lightning strikes have a way of finding ground via almost any odd path. 73, Eric /elecraft.com/ On 11/14/2018 4:38 PM, Don Wilhelm wrote: > The current stated turnaround time for Elecraft repairs is 3 to 4 weeks. > Given the staff techs with experience, that is the best that they can do.?

My K3 arrived in Watsonville on Oct 1, and was shipped back exactly 30 days later. That said, it was the first time my nearly 10-year-old K3 had been back to the factory and the first actual problem of any kind I?d had with it. At the same time, they installed the front panel board gold pins (which may have been the actual cause of the problem I was having), put a mod in the KPA3, added a bracket, aligned it, and checked it. I?d been sitting on a set of those gold pins for quite a while in my ?when I get a Round To-It? box of parts, and it?s probably too bad I hadn?t taken the time to put them in before some oxidation caused a problem. At least it?s done now, and I know my radio still meets or exceeds specs. 30 days was a small price to pay ? even though it was a lonely time :-) Grant NQ5T K3 #2091 KX3 #8342 >> >> >> >> The current stated turnaround time for Elecraft repairs is 3 to 4 weeks. >> 73, >> Don W3FPR From k9ztv at socket.net Wed Nov 14 21:20:11 2018 From: k9ztv at socket.net (K9ZTV) Date: Wed, 14 Nov 2018 21:20:11 -0500 Subject: [Elecraft] Possible K3s TX failure - distorted audio In-Reply-To: References: <276D3D6C9D5C8C4484211E9839FDE1AB4A396914@CITESMBX5.ad.uillinois.edu> <009301d46e77$d3558db0$7a00a910$@net> <5BD65B28.27529.1755B39@Gary.ka1j.com> <002e01d47c67$481ad220$d8507660$@net> <000201d47c79$cdc45470$694cfd50$@nwlink.com> Message-ID: <3956A010-22C8-4532-8B4D-CAF5AFD79100@socket.net> Good techs don?t come cheap, either, which increases overhead and inflates prices.

Certainly in some circumstances an external "interlock loop" could be useful to have, or a key switch on the front! On my TS870s, Menu 27 set to ON, utterly disables the front panel TX and Tune buttons, and both the Mic PTT, Aux TX line, VOX and the CAT TX command! It's state is remembered when powered Off too, so is useful if you have kids (or cats) in the house and when developing custom software that will use the radio. (The Aux port TX line needs to be used, so as to route digi-mode audio from that port to air, and mute the Mic.) Many Kenwoods also have a "feature" that if the Mic PTT is active when they are powered up, they will not TX, but locks out the transmit ability.? Many have been caught out by a faulty Mic that way! I don't know, but maybe Elecraft have implemented that last one, I've not tried that on the KX3.? If I remember, I'll try later. I do know that if you momentarily feed the KX3's Mic jack's PTT line a +ve voltage (I forget exactly, but somewhere greater than +3V) it will power up the radio from the OFF state!? Very useful for a QRP remote.?? Once "awake" the PTT line works as normal.?? A CAT command is used to power down the rig when you're done. 73. Dave G0WBX.

Message-ID: <20181115151943.UZEI4108.fed1rmfepo201.cox.net@fed1rmimpo209.cox.net> Norm and all, I bring mine down off the shelf every so often (a 4 bander), but not as often as it deserves! I still remember how much fun it was to build it, and how exciting it was when everything worked as predicted!!! The KX1 sort of lost momentum, partly due to subsequent alternatives, and partly due to lack of parts availability. When I first built mine it was only a two bander with two different boards to make it a 4 bander. Then they figured out how to get 4 bands on one board, and I upgraded. I just wish that had been an option from the get-go! Then, I guess, the 4 band board parts became problematic, and soon the K1 was not viewed as being as desirable as it once was. Somewhere along the way the KX1 came along, and that bifurcated interest as well. I have one of those too?in fact, I have at least one of almost everything except a K3S. The K1 is still a terrific radio. Even after I replaced it with newer models, I found it to be a particularly good choice for QRP Field Day! Now, though, it?s hard to justify opting for my K1 on Field Day when I have a KX2 and KX3 to choose from! Sort of an embarrassment of riches I guess. Anyway, my plan is to someday present that K1 to some deserving, young, new ham who needs a radio to get started?just like I did when I first got started. Of course, that means I have to identify someone truly interested in CW, but, well, that?s part of my definition of ?deserving?! Hi. In the meantime Norm, keep the ?Mojo? going! Cheers!

Having an issue with my KX2. Took it out /p on Saturday and connected it to my usual linked dipole for 20/40m, tuned and ran a nice little pile up on 40, split the links and hit tune on 20m and got 25.4:1 swr. Weird first time that?s happened. Closed the links and sure enough it tuned up for 40 fine. So I suspected the antenna is fine. Got home and connected the KX2 to a dummy load and it will tune on every band except 20. Maybe something has come adrift inside, I?m not sure.

The unit was powered on and it came up in operate mode while the HF radio was in TX at 100w on 6M. End result is that the magic smoke got out. :) Before I take it apart to find the offending part, a schematic would be useful. Now, no power out, not surprisingly.

But the list traffic is light because the K1 is, well, a less complex radio. I'm finally getting around to adding the noise blanker to mine, but it's a six-bander -- with a board swap.

Seems I was wrong. " According to the KPA500 Owner's Manual the KPA500 should react to excessive drive by first switching in the attenuator and, if that is not sufficient drive reduction, issuing hard fault 06 and dropping to STBY. Why was this KPA500 not protected? Are all KPA500 at risk of damage if driven with 100W? Will Elecraft be reviewing the fault log to see what went wrong? My standard procedure would prevent ever driving with excessive power. (Change bands, drop to STBY, send 5 W tune signal, read LP100A SWR, check TS-590 power setting, if power correct and SWR ok then select OPER). However, I know I'm fallible and it is a design goal that my TS-590 <> Elecraft interface will fully automate this sequence.

I set up the reference oscillator using Spectrogram and EA3ADV's method. Using 10MHz WWV (and a couple of iterations), I managed to get the frequency to read within 10Hz on 10MHz WWV and 5Mhz WWV and within 10-20Hz on 15MHz WWV (all higher in frequency). However, 20Mhz WWV is off by 80-90Hz lower in frequency - the direction of the error is as expected, but not its magnitude. I would expect the error to increase as the frequency increases, but this seems like a lot. Is this another "Don't worry, be happy" situation, or should I look for a problem? Also, the temperature of the rig and room do affect this! With the lid off, I put a towel over the open top for about an hour, then removed it and ~15 minutes later, the dial had drifted about 20Hz.

Actually it might be fun to do something like what you suggest on a lark, but not sure exactly how you ?weigh? the weight factor! Hi. For example, is the weight including, or excluding, batteries? I suspect a lot of KX1?s and KX2?s would become the rig of choice for those who have access to one. I might even opt for something like my super small ATS-3b rig which I still consider to be something of a marvel. --------------------------------------- From: Bill Frantz Perhaps we need some contests where the weight of the entire setup: radio, computer (if needed), power supply, antenna, and antenna supports is part of the scoring.

Li-Ion batteries are very fussy about the way they are charged. While it would be more efficient to run the charger directly on 12 Volts, such a charger for the Elecraft batteries is not available, as far as I know. Even if it were, it would probably cost more than the inverter. The inverter, of course, also has other uses. Elecraft also makes it very clear that their batteries shouldn't be charged with any other charger, and there are good reasons for that. 73, Scott K9MA On 11/16/2018 12:15, Dennis Moore wrote: > So you're taking your 12v source (let's say it's 13.8v), adding an > inverter to make 120v, then plugging in a charger to bring it back > down to 13.8v. > > I'm fairly new to the KX3 game, but it seems like I must be missing > something here. > > 73, Dennis NJ6G > > > On 11/16/2018 09:58, K9MA wrote: >> One solution to charging the Li-Ion batteries from a 12 V DC source >> is to use a small inverter.

Someone must have changed yours. The KPA500 can also be programmed to switch to standby on band changes. It defaults to selecting STANDBY or OPERATE per the last band change. When connected to a K3 using the KPAUX cables, the amplifier and the radio communicate and the radio will reduce power when you switch the amp to OPERATE. I run mine in Power up: STANDBY, Band change: Switch to STANDBY. Its harder to do stupid things in this configuration. I'd rather accidentally transmit at 100w than blow the amp up. Also, my KAT500 tuner can auto bypass the amp if the SWR reaches 2.5:1 threshold to protect the amp. This is also programmable. The menu settings for all of this are in the KPA500 Operations Manual on page 19. BTW, there is no T/R relay to click in the amp. It uses PIN Diode T/R switching. When you key the amp, and if you have it connected to the same PTT as the radio, you should see an asterisk (*) in the LCD window that tells you the amp is "keyed". You may have blown up the input attenuator. Or the RF deck. Or both. As a machine I used to work with said when its power supply was overheating: "$$$ UP IN SMOKE!". 73 Lu Romero - W4LT From: Michael Walker To: Andy Durbin Cc: "Elecraft at mailman.qth.net" Subject: Re: [Elecraft] Killed the KPA500 :) Message-ID: Content-Type: text/plain; charset="UTF-8" I have the schematics, as someone was kind enough to send them to me.

They should be able to help you with the situation. They may ask for a fault log from your KPA500 - if so please provide it. I will try to quickly turn around the analysis that I do each time one of these is requested. The KPA500 does have many protections for bad conditions. As others have stated, the KPA defaults to Standby at power on, but may be set to switch over to OPER mode shortly after power-up with a menu setting. This can be saved using the menu item: PWR-ON. That default value for that setting is STBY. When the KPA detects input power over 50 watts we will insert a 3db attenuator and continue operating. At this point the FAULT LED will be blinking to alert you as to the condition that needs correction. If the input power is over 60 watts for more than one half second or over 50 watts for 5 seconds we will go to a fault condition. If the input power is over 75 watts the KPA will immediately go to a fault condition. The KPA500 has a lot of checks and processes to correct problem situations. Excess power over an extended period or happening many times can damage the input network and lead to amplifier failures. As with any amplifier, avoiding that situation is always a good thing, and assures use of the amplifier for years to come. Let?s see what we can do to get you back on the air quickly. Again, please give customer support a call so we can get that going. 73, Jack, W6FB Elecraft Engineering > On Nov 16, 2018, at 6:58 AM, Michael Walker wrote: > > Sorry > > I don't use a K3 and it was a mistake in my in head checklist. > > Mike va3mw > > On Fri, Nov 16, 2018 at 9:56 AM Bob McGraw K4TAX > wrote: > >> You can configure the amp via the MENU to power up in the stand-by mode. >> Also have it go to stand-by when changing bands. >> >> You should have the amp connected to the K3 via the multi conductor cable >> and not use the amp key cable. >> >> The amp follows the radio and none of this will happen. >> >> Bob, K4TAX >> >> >> Sent from my iPhone >> >>> On Nov 16, 2018, at 7:52 AM, Michael Walker >> wrote: >>> >>> I have the schematics, as someone was kind enough to send them to me. >>> >>> Yes, I forgot the KPA500 powers up in Operate.

I went down this road a couple months back looking for something to run my KX2 mobile out in the boonies and still be able to charge without use of a geny. I stumbled upon an outfit out of VKland that seems to fit the bill. Company called REDARC: https://www.redarc.com.au/battery-chargers/in-vehicle-chargers They do have a US distributor now from what I can tell. Their unit also has Solar input - which would be a plus - and designed to handle the new "smart alternators" that are common on newer vehicles...I didn't know a thing about these newer alternators until I found this site. This is a common deal in VK with all the "overlanders". Dual batteries to run the fridge, radios, and other camp assy's while in the "outback". Charge off of solar while parked, 12vdc while in motion, to keep the LiFePO4's (aux battery) charged. I've used a goal zero inverter, and it works ok - if I don't use it and any radio gear at the same time. ;-) Todd KH2TJ K9MA wrote: > Hi Dennis, > > You're missing the charge controller.

Like tonight, at my QTH. 40 m is also a great local/emergency band, with many active regional nets. For such times, we may offer an extender for the AX1 that moves the 20 meter resonance down to 40 meters. A significant amount of additional inductance is required. The ATU built into the KX2 or KX3 provides any needed fine-tuning to efficiently cover the entire band, despite the unavoidably narrow-band nature of a short whip. I whipped up a prototype of the hypothetical "AXE1" this afternoon and had excellent on-air results. Tests were done in my back yard, featuring hard-packed soil and brown unwatered grass...in keeping with our legendary drought. With one call each I bagged British Columbia and Colorado. Both stations were peaking S-9, and both gave me reports in the S-5 range. This brings up an important caveat: a short whip is not the optimal antenna on 40 meters by any stretch, so calling strong stations is a good strategy. They could be strong due to propagation, good antennas, or high power, and two out of these three aid both ends of the QSO. The extender would be about 6" long and 1/2" in diameter. (Even a small amount of added length helps on 40 meters.) It threads into place between the AX1's whip and base, and adds just 1.8 ounces of weight, still consistent with hand-held use of the KX2. Equally important, for those of us who travel light, the extender -- plus a counterpoise wire for 40 m -- fits comfortably into our smallest bag, the CS40, along with the AX1 and an AXB1 whip bipod. (In answer to the inevitable question: it *might* also work on 30 meters in a pinch, with an ATU, but efficiency would be lower.) If you'd be interested in AX1 use on 40 meters, please email me directly. I won't necessarily be able to respond, but this will help us gauge interest. We'll keep a list for possible early announcement. 73, Wayne N6KR From tjdooley at comcast.net Fri Nov 16 21:04:23 2018 From: tjdooley at comcast.net (Tom Dooley) Date: Fri, 16 Nov 2018 21:04:23 -0500 Subject: [Elecraft] AX1 may add 40 meter coverage with "AXE1" extender In-Reply-To: <50656909-6B14-439C-8EDE-5C85D28FB541@elecraft.com> References: <50656909-6B14-439C-8EDE-5C85D28FB541@elecraft.com> Message-ID: <3E8B606C-DAAE-483B-9E15-DFA0BB75EC6E@comcast.net> Hi Wayne.

The pack has charge controller PCB to prevent over charge or under discharge. It does NOT provide the connector for balancing the cells. I bet you have one of the 12.6V Li-ion chargers there now. It probably looks like a 12.6V wall wart with an LED in it. Best DC-DC charger option is RC plane equipment like iMax B6 at ~$29 (Amazon). The more expensive ones also have AC input so you can use them anywhere. If you aren't addicted to the shrink wrapped packs, inexpensive 3-cell 18650 battery holders are available on eBay that allow you to manage your cells independently. BTW, you will probably need to change connectors to APP.

I went down this road a couple months back looking for something to run my KX2 mobile out in the boonies and still be able to charge without use of a geny. I stumbled upon an outfit out of VKland that seems to fit the bill. Company called REDARC: https://www.redarc.com.au/battery-chargers/in-vehicle-chargers They do have a US distributor now from what I can tell. Their unit also has Solar input - which would be a plus - and designed to handle the new "smart alternators" that are common on newer vehicles...I didn't know a thing about these newer alternators until I found this site. This is a common deal in VK with all the "overlanders". Dual batteries to run the fridge, radios, and other camp assy's while in the "outback". Charge off of solar while parked, 12vdc while in motion, to keep the LiFePO4's (aux battery) charged. I've used a goal zero inverter, and it works ok - if I don't use it and any radio gear at the same time. ;-) Todd KH2TJ K9MA wrote: > Hi Dennis, > > You're missing the charge controller.

Is that one for 20m which is probably the most likely the best chance for getting this ATNO? When the Peter I Island (in the same general area) expedition was out there, I could hear nothing but a whisper from them (and as the saying goes, if you can't hear'em you can't work'em, and sure enough I didn't), but I do have better antennas now for points south. I kind of reckon that if I can't hear them with my regular transmitting antennas, they won't hear me with my 100W on the same antennas either. So I have never bothered with erecting special receiving antennas. I don't have the acreage for it either. But I am crossing my fingers that this DX-pedition will succeed (and be heard up here with no exceptional receiving antennas). AB2TC - Knut David Olean wrote > Darn!

You can find some excellent choices on sites such as qth.com and eham.net. I've bought and resold 5 or 6 units since my very first SN #111 since I like to trade up to the latest production versions (now on #86XX). I're made enough on these units by stripping out options I don't need and reselling them separately for higher prices such that the total net cost of my current unit is probably zero or maybe even a net profit. Here are a couple of units on qth.com (click Search Ads at the top) that are worthy of consideration: Elecraft k3/100 100 watt transceiver; KAT3 Auto Antenna Tuner: KBPF3 General Coverage Receiver; KFL3A-28k 2.8khz 8 pole filter; K3FLA-400 400hz 8 pole filter; power cord; all manuals. SN23xx---no holes, blemishes, or dents. Never operated mobile or portable. Nicotine and pet free environment. $1450. Elecraft K3 / 100 Pristine condition- Radio has 2.7 filter ,KAT3A AT, KPA3A 100 watt amplifier Powerpole power cable, Manual, Latest firmware installed. $1450 plus shipping. $1450 is still a LOT of money for many of us, but a bargain compared to buying a brand new K3S, and you're getting about 95% of the performance.

During the contest, I repeatedly noticed that the KAT-500 was not re-tuning automatically to adjust to frequency changes based only on my SSB transmissions. But I found that if if I switched to CW for a couple of brief transmissions, the KAT-500 quickly re-tuned and reduced my SWR to near 1:1, so I could then switch back to SSB and complete the contact. [I retune the SteppIR manually as I change frequency, but the beam is only 40 feet up, and interacts with lots of trees, power lines, and other problematic structures close to my tiny 100 by 100 foot property, so the antenna itself is not always perfectly matched.] Has anybody experienced this problem or solved it? 73 - Rich, K1DJ Sent from my iPad From ai4ns.mike at gmail.com Mon Nov 19 08:04:41 2018 From: ai4ns.mike at gmail.com (Mike Short) Date: Mon, 19 Nov 2018 07:04:41 -0600 Subject: [Elecraft] KX2 battery options.

In-Reply-To: References: Message-ID: I've done both, for my KX3, using cells salvaged from old laptop batteries. 4 cells: at full charge, pack voltage is too high for the KX3. On the flip side, nominal pack voltage will remain high enough for the radio to operate at higher power until the pack is nearly dead. I've dealt with this two ways: 1) only charge the pack up to ~15.5v. This keeps the peak voltage within the acceptable range, but sacrifices some capacity. It may also increase the longevity of your cells (i.e. allow more charge cycles). It may also prevent any cell balancing from ever happening. 2) Charge the pack fully and use a buck converter until pack voltage falls off a bit. This will allow you to maximize the pack capacity but keep the input voltage where the radio wants it. The downside is the possibility of birdies (buck converters are switchers) and having to carry yet-another thing. Some power is "wasted" by the buck converter, but it can be removed from the equation pretty quickly (it doesn't take terribly long for the pack voltage to drop to where the radio is happy). 3 cells: peak pack voltage is perfectly acceptable for the radio, but may not allow operating at full power. Nominal pack voltage (11.1v) also won't allow full power out. When the pack is near dead, output power may need to be significantly reduced. I've dealt with the 3 cell pack by using a boost converter. This allows for higher output power but sacrifices efficiency (some power "wasted" by the boost converter), and may result in birdies from the converter. Since I already have both 3- and 4-cell packs, I use both of them. I ended up picking up a boost-buck converter. It's pretty small (deck of cards), and hasn't created any RFI that I've noticed yet -- even operating out in the field where the noise floor is very low. It lets me use either pack on the input side, and set the output voltage where I like. I can run the KX3 at 15W until the packs go dead. I've also used it with my Bioenno LiFePO4 pack if I needed a little more power to complete a contract. -detrick K4IZ On Mon, Nov 19, 2018, 08:07 Mike Short I have a bunch of 18650 batteries.

Also, after doing the training, I normally operate the KAT500 in the MANual mode. Also in the K3S manual, see KAT3 topic, page 60, for information on establishing VFO tracking with the KAT500.? When VFO tracking is enabled, the KAT500's L network will be continuously updated as the VFO is tuned. 73 Bob, K4TAX On 11/19/2018 11:07 AM, ANDY DURBIN wrote: > "Has anybody experienced this problem or solved it?" > > > I don't expect my KAT500 to re-tune with an SSB transmission since I send it the exact TX frequency before I start to transmit.

You should train the antenna (using TUNE) on all bands and all antennas at 25kHz intervals for each band. Then change the KAT500 to MAN. The KAT500 will follow your frequency and change to the pre-set L/C values for that band and antenna automatically. If you have the latest firmware, it will even follow the K3/K3S in receive. 73, Don W3FPR On 11/19/2018 5:28 AM, K1dj via Elecraft wrote: > I am primarily a CW operator, but participated in the SSB Sweepstakes over this past weekend, running low power (100W) from my K3S, which runs through my KPA-500 and KAT-500 to a SteppIR 3-element beam with the 30/40 meter loop), a 40 meter wire dipole, and an 80 meter wire inverted V.

Use the tripod mount option and a short piece of coax. 73, Don W3FPR On 11/19/2018 6:46 PM, Bill Robbins wrote: > I have yet to see comments here regarding the use of the AX-1 with the > K2 or K1. > > Any experiences or thoughts. > > Bill > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to donwilh at embarqmail.com > From va3mw at portcredit.net Mon Nov 19 19:51:46 2018 From: va3mw at portcredit.net (Michael Walker) Date: Mon, 19 Nov 2018 19:51:46 -0500 Subject: [Elecraft] Killed the KPA500 :) In-Reply-To: References: Message-ID: <6059F4D7-207E-4BD8-8A6D-2D37E33A68B3@portcredit.net> Knowing what I did while transmitting at 100 watts of msk144, I?m surprised the damage isn?t worse. The protection circuits did the best they could of. If you own any amp, you always need to be aware of the risk. I would never rely on the automation to 100% protected any amp. If you are worried about your amplifier and anyway I highly recommend you have checklist handy every time you turn it on and change Bands. Never depend on the protection circuits. I know I?m preaching to the choir too many people, however it is imperative you understand exactly how your amp works, how it?s wired, and how it interfaces with any HF radio.

Here's what I wrote: Here are a couple of observations on using the AX1 on the K2/10 with internal tuner. First off, I know that this is promoted for the KX2/KX3 and similar radios, the AX1 page doesn't list the K2 as a compatible product and probably doesn't get much use in /PM. With the K2 sitting flat, the AXB1 Whip Bipod legs aren't quite long enough to be effective. They do touch the table with maybe 1/2" of space between the legs. If you're using the K2 on an uneven surface they may not provide any support at all. I think another 1/4" - 1/2" of length would solve that. With the bail extended and the front of the K2 elevated the legs work fine but of course the antenna is no longer perfectly vertical K2 internal tuner tests were performed with the whip fully extended and the supplied radial wire laid out to its full length and tightened under the ground post as well as it could be. The pre-installed lug does not fit around the ground post. Switch position was appropriate for each band tested. On 20m the internal tuner found a good match wherever I was in the band. That is to be expected as the antenna was designed for 20m with no tuner. On 17m the best match I could get was 3.3:1, and on 15m I got a 1.1:1 match pretty much throughout the band. I don't know what caused the issue on 17m since it worked fine on 20 and 15. On my KX3 the AX1 tuned up fine on all three bands so I don't suspect an issue with the antenna, it must be the K2 tuner although it tunes other antennas well on 17m. I'll do some more playing around and if I get different results I'll post them. 73, Dennis NJ6G On 11/19/2018 15:46, Bill Robbins wrote: > I have yet to see comments here regarding the use of the AX-1 with the > K2 or K1. > > Any experiences or thoughts. > > Bill > ______________________________________________________________ > 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 dennis at mail4life.net From k4to.dave at gmail.com Mon Nov 19 20:46:12 2018 From: k4to.dave at gmail.com (Dave Sublette) Date: Mon, 19 Nov 2018 20:46:12 -0500 Subject: [Elecraft] Bluetooth Noise cancelling headphones Message-ID: Good evening, A few days ago I posted a question about using Bluetooth headsets and the latency problem. I got no answers, so I just took the bull by the horns and ordered something. Today I received the Avantree Audikast aptX low latency transmitter and the Avantree ANC031 Active Noise Canceling Headset. After three hours charging the headset, per the instructions, I hooked it all to the headphone output of my KX3. It works! There is no detectable latency. I can send and receive Morse without stuttering. I can't hear any latency at all. I walked the entire length of the house, about thirty feet in each direction with walls, etc. I can hear the receiver just fine. One end of the path is in the garage where my workshop is. That gives the possibility of listening to a fixed or scanned set of frequencies while I am working on something else. In short, it appears to be just what I wanted. Now I won't try to break my neck or drag all the radios off the table when I jump up to go get another Pepsi out of the fridge. :-) No connection to selling these products here. Just reporting the results to to this point. I may report again after I have used it awhile. The battery charge is advertised for 40 hours. I'm sure I will put that to the test. 73, Dave, K4TO From a.durbin at msn.com Mon Nov 19 21:16:44 2018 From: a.durbin at msn.com (ANDY DURBIN) Date: Tue, 20 Nov 2018 02:16:44 +0000 Subject: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW In-Reply-To: References: Message-ID: "when the KAT500 receives a burst of RF, it will tune to the remembered L/C combination for the frequency received, it will go immediately to that combination."

They're a folding set made by MPOW that I don't think they make anymore. You can also plug a 3.5mm stereo patch cable into them and not turn on the Bluetooth section, though you can still turn on the active noise cancelling separately. I've used them with several devices and they seem to work well. I've used then with the patch cord to the KX3 headphone jack, and they work just fine, but that's scarcely a test. I don't know how I would test the Bluetooth function with the KX3, as the rig doesn't have Bluetooth output that I'm aware of. I'd have to use a separate Bluetooth transmitter, which I don't currently have. The headphones I used are these, that I purchased at the time on Amazon. Unfortunately, they are no longer available. https://www.amazon.com/gp/product/B00LBO0PWM These appear to be a more recent model with similar functionality. https://www.amazon.com/Mpow-Cancelling-Bluetooth-Headphones-Noise-Cancelling/dp/B07GF8T9VT/ Gwen NG3P On Mon, Nov 19, 2018 at 9:44 PM GaryK9GS wrote: > Hello Dave,Do you have a link for what you purchased?73,Gary K9GS > -------- Original message --------From: Dave Sublette > Date: 11/19/18 7:46 PM (GMT-06:00) To: Elecraft Discussion List < > elecraft at mailman.qth.net>Subject: [Elecraft] Bluetooth Noise cancelling > headphones Good evening,A few days ago I posted a question about using > Bluetooth headsets and thelatency problem.

You must "train" it by transmitting in every segment for each band/antenna combo you have, but once trained, it's solid. The segments are small on 160 and 80 [10 KHz? I don't remember, someone on the list probably knows], and get larger as you go up in frequency becoming 100 KHz or so at 10 m and maybe twice that on 6.? With the KAT500 in AUTO, tune to the center of each segment, and press ATU TUNE if you have a K3, or just transmit if you are using a non-Elecraft transceiver.? It takes anywhere from 20 - 25 or so watts to tune. Once you have hit every segment with every antenna that works on that segment, switch to MAN and leave it there.? The KAT500 utility will let you specify which of the 3 antennas are usable on each band and won't put others in the antenna selection cycle.? To switch antennas, just tap the button to get the desired antenna. The selection of tuning parameters is as fast as it takes for the relays to close when you first transmit.? It worked fine for me when I still had my KAT500 on CW, SSB, and RTTY.? IMI: Operate in MAN, not AUTO. If you have a K3/K3s and the cable between them installed and the KAT500 connected, the tuner will follow your receive QRG, selecting the correct parameters as you tune, but the RF sense is nearly instantaneous without the cable or a K3/K3s.? IMI: Operate in MAN, not AUTO.? Every time someone has asked me to help them, and despite the "Operate in MAN, not AUTO" advice from this list and others, I get there and find they're operating in AUTO. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 11/19/2018 4:43 PM, Don Wilhelm wrote: > The KAT500, will do the same for any transceiver - except for > following the receive frequency. > After training the tuner, when the KAT500 receives a burst of RF, it > will tune to the remembered L/C combination for the frequency > received, it will go immediately to that combination. > Train in AUTO mode, then switch to MAN for reliable operation. > > 73, > Don > W3FPR From hs0zed at gmail.com Mon Nov 19 22:26:22 2018 From: hs0zed at gmail.com (Martin Sole) Date: Tue, 20 Nov 2018 10:26:22 +0700 Subject: [Elecraft] Data troubles Message-ID: <6c8ea13d-8449-ca9d-edd2-1a1ed312afbf@gmail.com> Can anyone help with a quick DATA mode problem.

I can actually hear net control with a marching band next to me. (I also use a noise cancelling mic.) I haven't used them during CQP, but the RadioSport headphones I used last time really kept the outside chatter down. They should be useful in a tent/room of SSB operators.

I will do more reading in my Elecraft manuals and Cady books and adjust accordingly. This is a wonderful reflector! The one additional complicating factor for me is that there are so many interfering objects close to my SteppIR beam and low (40 foot) tower that the antenna impedance changes pretty significantly as I rotate the beam. So a perfect solution (probably beyond my meager abilities) would require me to train my KAT-500 to recognize and adjust for various frequencies AND antenna headings.

It made me focus on proper use of my KPA500 which has really done a great job for me since I acquired it and a KAT500 over the summer. Retitled this message because I do not want to hijack/derail the original conversation. What I want to know... is there no repair for absent minded button pushing and thoughtless antenna positioning? So that I don't forget again... A hopefully instructional "mea culpa" follows: I have been using the IC-7000 for 2M APRS ops with a Diamond VX2000 vertical. Also have been experimenting with HF simplex D-Star and Free DV digital voice recently. The KPA500 has been instrumental for DV ops because of recent squirrely propagation... Mistake 1: Over the summer, I forgot to shut down the packet ops and ground 6/2/440 tri-band antenna while using a "nearby" halo with 350 watts 6M DV. That blew the 2M front end of the IC-7000. Matt at SARTS/ICOM in Michigan repaired it and I put together a protection relay circuit to ground the vertical if I forgot again. That should have solved the issue... Mistake 2: A relay contact was faulty (and I did not test it properly) and a month later, an adventure on 6M DV mode took the 7000 front end again! Matt was kind about fixing it ...again... Here I claim total stupidity along with absent mindedness - I rebuilt the protection circuit, tested it, it "seemed" to work fine... but it failed again a month later! Mistake 3: Failed, because I had removed the dummy load and *forgotten* to replace it along with a key ground strap, which again left the receiver 2M front end exposed. Kindly, Matt agreed to fix the 7000 a 3rd time... The 7000 will not go back into service until I have completely re-arranged the station set up because, to top off this comedy of errors... I totally ignored one basic issue: Original Mistake: the vertical and halo antennas were mounted on the same mast because "I never planned" to use them at the same time. This is where stupidity/laziness compounded with my absent minded operating practices to create the "perfect storm". Until I started using the KPA500, the halo antenna field strength was not such that the 7000's 2M receiver section was stressed by the signal strength from vertical, so I got complacent. Add in the KPA500 and smoke is let out of Q551 in the IC-7000.

This is for the none Elecraft radios when using the Icom I *REMEMBER* to have drive power set and the amp is in STBY. Set the KPA500 menu for standby when power up or changing bands good insurance. With the K3 the freq info is automatic ...again do not run the KTA500 in AUTO mode it takes very little power for the tuner to see what is going on. My reason for running it in MAN mode is if the weather changes my wire antenna impedance Auto mode *might* try to re tune hot switching it.

Phil N3ZP From a.durbin at msn.com Tue Nov 20 11:27:07 2018 From: a.durbin at msn.com (ANDY DURBIN) Date: Tue, 20 Nov 2018 16:27:07 +0000 Subject: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW In-Reply-To: References: , Message-ID: "It does not make any difference whether he is using RF sensing or not." Don, Since I have trained my KAT500, I had assumed the OP had done that as well. I was thinking that the problem was that the SSB phone transmission was not causing the KAT500 to switch to the memorized tuning solution. I can see now that I had misunderstood the problem. I never use my KAT500 in any mode except MANUAL. AUTO takes control away from me and, in BYPASS mode, memorized antenna selections do not work correctly. In my station my KAT500 and my SteppIR follow the transmit frequency of my TS-590. This avoids any re-configuration at start of TX for cases where TX and RX frequencies are not equal. 73, Andy, k3wyc From wb6rse1 at mac.com Tue Nov 20 11:42:01 2018 From: wb6rse1 at mac.com (wb6rse1 at mac.com) Date: Tue, 20 Nov 2018 08:42:01 -0800 Subject: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW In-Reply-To: References: Message-ID: K3 + KAT500 via Aux Bus 1 - Train the KAT500 2 - Switch to Manual Mode 3 - Turn on K3 frequency tracking.

You can find some excellent choices on sites such as qth.com and eham.net. I've bought and resold 5 or 6 units since my very first SN #111 since I like to trade up to the latest production versions (now on #86XX). I're made enough on these units by stripping out options I don't need and reselling them separately for higher prices such that the total net cost of my current unit is probably zero or maybe even a net profit. Here are a couple of units on qth.com (click Search Ads at the top) that are worthy of consideration: Elecraft k3/100 100 watt transceiver; KAT3 Auto Antenna Tuner: KBPF3 General Coverage Receiver; KFL3A-28k 2.8khz 8 pole filter; K3FLA-400 400hz 8 pole filter; power cord; all manuals. SN23xx---no holes, blemishes, or dents. Never operated mobile or portable. Nicotine and pet free environment. $1450. Elecraft K3 / 100 Pristine condition- Radio has 2.7 filter ,KAT3A AT, KPA3A 100 watt amplifier Powerpole power cable, Manual, Latest firmware installed. $1450 plus shipping. $1450 is still a LOT of money for many of us, but a bargain compared to buying a brand new K3S, and you're getting about 95% of the performance.

I acquired it a year ago from another amateur. He demonstrated it for me and I saw that it worked. I have not used it since then. Included is: - Elecraft K2/100 HF Transceiver with 100W amplifier and I/O module - K2DSP internal DSP filter and real-time clock - KSB2 SSB adapter - KNB2 noise blanker - K60XV 60m and transverter adapter - K160RX 160M module - External KAT100 automatic antenna tuner It's in good condition and everything works. However, as I said I never sat down and used it. Instead, I retired and moved to Thailand where I now live. I wanted a K2 because it's on the Thai government's short list of type approved transceivers, i.e., it doesn't cover 6m or 70cm, which aren't currently legal bands here). Once I arrived I discovered that I can't ever get a Thai ham license because Canada doesn't have a reciprocal licensing agreement with Thailand. So the K2 is of no further use to me. The equipment is still in Canada. My friend VE3EG, Keith is handling the sale and shipping on my behalf. You can direct questions to me, but I will turn things over to Keith once we have ourselves a deal. I'm reducing the price for the package to Cdn $1,350 (about U.S. $1,017 at current exchange rates). Shipping is extra and is based shipping from Toronto to your QTH. Many thanks and 73!

You can set up the hardware buttons for whatever you want, so it?s very convenient to make quick changes to span, etc. SDRPlay is cheaper and can integrate with other software to show spots on the waterfall, etc. I started with a softrock and a sound card for a pan adapter, then moved to SDRPlay, then bought a P3. I don't miss the dependence on the computer, or the larger screen. Your mileage may vary.

I want to say thanks for the recent thread on the situation one member had with the Autotune between SSB & CW. I drive my KAT500 with an Icom IC-7300 and using the "Tune it in AUTO - Operate in MAN" scenario works perfectly. It even remembers different tunes for different antennas. I have a DXE 43' Vert for DX on 30 & 40M on ANT2 and a dipole for 40 & 80M for local chats on ANT3. The more I use this tuner the more impressed I am. I am presently waiting for a local ham to decide to upgrade his second station from a KPA500 to a KPA1500, as I am in line for that when he sells it.

I use the RSP for spectrum display and LP Pan with a good sound card for CW Skimmer; Yes, they are in parallel. I would say there is an advantage to using a software spectrum display vice a P3; my feeling is that there is more flexibility. I run my spectrum display, Win4K3, as a way to tie all of the software I use together for tracking and control and logging. If you go with the P3, you will still need some software to integrate station functionality. The real question is just how much spectrum do you really need to display. About 100 KHz works for me most of the time. That means a sound card that samples at 192 KHz. should be adequate, but there is always the desire to see more, whether you really need it or not. It's been a while, but as I recall I can see about 1 MHz. using the RSP. For chasing DX in split mode, I usually run about 50 KHz on my 24" monitor. This way I can see where the DX station is hearing. The way you operate will dictate what bandwidth you will use and when. 73, Barry K3NDM ------ Original Message ------ From: "Bill Weaver" To: "elecraft" Sent: 11/21/2018 1:17:12 PM Subject: [Elecraft] P3 v.

Here's what you need to know once you have the K3S talking to N1MM: On the K3S, navigate to the 'PTT-KEY' Config option and set it to 'rts-dtr'. Leave VOX turned off. In N1MM: with the port to match your K3S and SOxx set as desired, then: N1MM will send PTT and CW via the USB port. I have a K3 (not S) but the only difference in this case is your radio has a built-in USB to serial converter. 73, -John NI0K Jim Cary wrote on 11/22/2018 10:46 AM: > I?m trying to get my K3S and N1MM+ to work on cw without an interface (which I have used in the past).

Once I realized that the cw and ptt were controlled through the same port on the same line as the radio, all went well. As usual, an ?operator head space problem? 73 and have a Happy Thanksgiving.

SDRPlay RSP1A for panadapter In-Reply-To: <@localhost> References: <@localhost> Message-ID: Bill, The P3 is designed specifically for use with the K3/K3s line. It has features like function buttons for rig and display control, click on a signal to change the vfo(s) to that frequency, split display for both spectra and waterfall, updatable firm/software, etc. None of this is available with any of the play units without supplimental programs. The eye appeal of the P3 sitting beside the transceiver is hard to beat but, with the P3, the size of the display is fixed where with a play unit the size of the display is up to you and your budget. To me, the drawback with a play unit, beside the above, is the requirement for a computer and monitor to process and display the image. If the function buttons, split spectra/waterfall display, and VFO versatility is of little interest to you, the play units will save you a sack of bux, assuming you already have a computer and monitor.

Message-ID: <5ffae0bc-f910-bf40-5bd8-946cfab70a68@swsports.org> Season's Greetings to everyone on the list. I've been trying to set up for digital communications and I am having some trouble getting the computer to communicate with the KX3. I keep getting hamlib errors - the latest is "communications timed out while opening connection to rig".... Instead of jamming the already busy list, can somebody point me in the direction of some plain language (not technobabble) instructions on setting my KX3/SignalLink up for FT-8. Before anybody gets snarky, the computer industry passed me by many years ago and at my age, I'm willing to reeducate myself on all things computer, but I have to start somewhere. Thanks in advance.

Put the COM port number that your computer assigned to the KXUSB into Hamlib and see if it connects. If you still cannot connect, start KX3 Utility and see if that can connect - if it does, then you have some kind of configuration problem with Hamlib (in other words, the KX3 is working fine). Set the KX3 to DATA A data submode. For setting the audio levels, please refer to my website www.w3fpr.com.

Message-ID: <1543113354346-0.post@n2.nabble.com> We are operating a K3s remotely and varying conditions/operator styles make it necessary for us to adjust VOX delay for CW. Searching the archives I noticed that a software command to adjust VOX delay was on the "short list" in 2011. I can do a SWH57 to get to the adjustment, but I can't find any command to actually change the value, which makes me wonder why bother with SWH57 at all. There is an SD command for QSK delay, but it is GET only. Is this still on the "short list" or have I missed it?

The CM500 does not qualify. However, my hearing in the low frequency region is close to normal, so I remove my hearing aids when I use my CM500. Not all older hams have that advantage.

(#8331) that was fully loaded (upgraded it with all the new boards).? Purchased the K3S with the 100W amp, tuner, and 400 Hz filter at Dayton the year it was released, and ended up building serial number 10038.? I tore out the sub receiver, Voice Recorder, three additional filters in the main and sub receiver, and High Stability Ref Oscillator from the K3, and moved them to the K3S. My K3 options were now the 100W amp, tuner, and 400 Hz filter, and it became my standby radio (I have used it at Field Day for the CW station for the last few years). So, yes; if you do not need to sell it for financial reasons, I would suggest you keep it. Dick, K8ZTT On Sunday, November 25, 2018, 1:47:18 PM MST, Dennis L.

The SELECT knob on the PX3 is not just an auxiliary tuning control. So if you?re twirling the knob and expect the frequency to change, it won?t. You can turn on say Marker A, and use the SELECT knob to move the marker. That by itself won?t do anything but move the marker. But then, if you PRESS the knob, the frequency will change to match the marker. But it is not just a tuning control ?

It is paired with a K3. It survived about 24 hours of operation, though it faulted a few times, as described below. Clearly, the protection circuitry did its job. Firmware is 1.87. A couple glitches: The power gain drifts downward as the transistors heat up. If I start out at 1500 W, it will drift down to about 1100, without changing frequency or SWR. Conversely, if I turn the drive up after the amp is warm, and forget to turn it back down, the amp will fault when cold. Since the amp is talking to the K3, couldn't some clever software fix this? Despite setting tune power to 40 W, the ATU sometimes just won't get the SWR below 1.4:1 or so. This is with antennas below 2:1, and the ATU stop set to 1.0. This happens on 40 meters, so it's probably not an ATU L/C resolution limit. This 1.4:1 SWR is sometimes high enough to limit output to well below 1500 W due to high drive power or high current. I have not yet tried manually tuning the ATU to see if I can get the SWR lower. Finally, after "training" the ATU across the band, I sometimes find that the SWR has gone up significantly at some frequencies. I don't believe this is due to changing antenna SWR. It seems more like the ATU has "forgotten" the settings, or tried to retune itself without permission. (HiSWR RETUNE OFF) Has anyone else seen similar issues? 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From kl7uw at acsalaska.net Mon Nov 26 20:20:36 2018 From: kl7uw at acsalaska.net (Edward R Cole) Date: Mon, 26 Nov 2018 16:20:36 -0900 Subject: [Elecraft] FS: New CM500 headset Message-ID: <201811270120.wAR1Kplr009925@mail40c28.carrierzone.com> Well I got quite a few comments back on the CM500. Firstly, I have extreme hearing loss. Without my Phonac-Silvia hearing aids the world it very quiet. I have something like 30-dB loss in both ears so not wearing them with headphones is not an option. As many of you may know, hearing loss is not simply lack of volume. I have a lot of problem with speech recognition. For instance even wearing my hearing aids (which cost me $5200) I still need closed-captioning when watching TV (at any volume). Hearing weak-signals on ham radio I use my headsets a lot (while wearing the hearing aids). My (now pretty old) Sony MDR-V600 stereo headphones do pretty well. Never any feedback with my over the ear aids). Unfortunately the acoustic design of the CM500 produced immediate and continuous feedback. I bought them along with the AntLion boom mic for comparison. The AntLion installed on my "old" Sony headset work just fine and I got great audio reports with the boom mic. So that made an easy decision not requiring engineering solutions or "fixes" by my audiologist. Main purpose was acquiring a boom mic for portable operating situations. Also hearing SSB with either NB or NR causes enough distortion of the sound to make it harder to understand speech (yes I have tried all the different settings). My hearing rolls off at 1000-Hz so I lose the consonant sounds. Lake/take/bake/make... all sound like eight or ate. Digital modes work well for me: I can read FB; volume can be set to zero. When I run my 1500w amp for eme I do not wear my hearing aids to lower blower noise (probably > 120 dba). CW I would need 40-dB or higher isolation in the headset. I'm moving all my QRO amps out of the shack for this reason (and for less coax line loss). Thanks for all the helpful suggestions. Simple solution was to sell the CM500. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From clawsoncw at gmail.com Mon Nov 26 20:22:22 2018 From: clawsoncw at gmail.com (Carl Clawson) Date: Mon, 26 Nov 2018 17:22:22 -0800 Subject: [Elecraft] (OT) CQWW CW band noise In-Reply-To: References: <35b2a5b2-8711-2ddd-2b11-82dd24bfa0cc@verizon.net> Message-ID: I guess it depends on your location.

See the K3 menu CONFIG: CW QRQ. That mode will allow clean CW keying up to 100 WPM. However, the transmit and receive frequencies must be shifted with each code element, and further if RIT, SPLIT or XIT are turned on, QRQ mode will be automatically turned off. For the best results for high speed CW, install the new synthesizer(s) in a K3 that has not yet been upgraded. The frequency can be changed more quickly than with the old synthesizer. 73, Don W3FPR On 11/27/2018 8:01 AM, Mpridesti via Elecraft wrote: > Been having issues with the quality of the CW sending from my K3.

The new synth board alleviates these CW problems ("faster CW break-in and more accurate CW timing" as compared with the original KSYN3 board). Second question: What is the CONFIG:TX DLY set to? If it is anything above the minimum (8 msec), that can result in "choppy" CW (shortened elements, less accurate timing). Third question: Do you have CONFIG:CW QRQ turned on? This improves CW timing at high CW speeds, but it turns off automatically if RIT, XIT or SPLIT is on. You are less likely to need CW QRQ on if you have the new synth board installed. This is not just hearsay; the issues with TX DLY and CW QRQ are described in the K3 Owner's manual. 73, Rich VE3KI K1RX wrote: Been having issues with the quality of the CW sending from my K3.

That can cause signal strength changes at 6.0 MHz similar to what you report. With ATU MD in AUTO, I get some signal drop at 6.0 MHz increasing. With ATU MD in BYP, I get absolutely NO signal change at 6.0 MHz, increasing or decreasing. The mystery is that you report the signal strength changes at 6.0 MHz even with the KXAT3 ATU MD in BYP. I am at a loss. There should be no relay operation in the KX2/3 at 6.0 MHz if the KXAT2/3 ATU MD is BYP. Do you hear any relay operation at 6.0 MHz with ATU MD in BYP?

I have at least 40dB. across the spectrum, in one ear, and 15dB at 500Hz, degrading to 70dB at 8kHz, in the other, and I'm only classed as having a moderate loss. These figures are a few years old, so the current ones are marginally worse. If you have severe enough loss to need full ear moulds, I think all modern aids have various options to directly feed the aid with, at least mono, audio, and some headsets will naturally work with aids that can be set to an induction loop setting. Typical options for full stereo, are blank headsets, that just create an induction field, ear hooks that hook over the ear and create an induction field, and direct audio input shoes that plug into over the ear aids, and allow a copper connection to the aid. For most aids you can get a bluetooth adapter, that you wear on a, conductive, neck loop. This is generally mono. You can typically provide a copper audio feed to these, in which case there is no bluetooth (the near field link uses a different protocol, and at HF, not SHF), or you can remote bluetooth adapters, which have low latency, as well as the normal bluetooth adapters, with their high latency. The Phonak brand name for this feature is ComPilot. My aids are Oticon, for which it is ConnectLine. I think the open fit aids, used by people with, typical, age related, high frequency loss may be more of a challenge, as they are designed to pass the low frequencies directly and only amplify the high ones. -- David Woolley Owner K2 06123 On 27/11/2018 01:20, Edward R Cole wrote: > Firstly, I have extreme hearing loss.

Because of this I have tuned all my segments manually. I find if the SWR is not adjusted to be close to 1:1 in all segments of a band then the drive requirements vary across that band, which would be very annoying. In addition the tuner may not always be in the segment you think it is. This is due to the 8KHz resolution of the internal counter, that wins over you sending it a more accurate frequency, and also the hysteresis algorithm that can require a 2 segment frequency change before the tuner changes. Gary from Elecraft says "if you are off by one bin segment then it should not matter too much" I also note that when into a perfect 50 Ohms, and the tuner bypassed, on 6 meters, my KPA1500 says the SWR is 1.4:1. On 10 meters it reads 1.2:1. Rene from Elecraft says "this is the best they can do".

Grounding, RF and impedance issues, etc., all can contribute to inconsistent behavior. The Elecraft tuning is among the best for price for in rig performance IMO.

Because of this I have tuned all my segments manually. I find if the SWR is not adjusted to be close to 1:1 in all segments of a band then the drive requirements vary across that band, which would be very annoying. In addition the tuner may not always be in the segment you think it is. This is due to the 8KHz resolution of the internal counter, that wins over you sending it a more accurate frequency, and also the hysteresis algorithm that can require a 2 segment frequency change before the tuner changes. Gary from Elecraft says "if you are off by one bin segment then it should not matter too much" I also note that when into a perfect 50 Ohms, and the tuner bypassed, on 6 meters, my KPA1500 says the SWR is 1.4:1. On 10 meters it reads 1.2:1. Rene from Elecraft says "this is the best they can do". Other than the issues above I am very happy with the KPA1500. - Paul From k2vco.vic at gmail.com Tue Nov 27 15:15:06 2018 From: k2vco.vic at gmail.com (Victor Rosenthal 4X6GP) Date: Tue, 27 Nov 2018 22:15:06 +0200 Subject: [Elecraft] Wish I had a KAT1500 In-Reply-To: References: <9e6caa1f-5e9a-11e3-edbf-b5f16a212b37@gmail.com> <8dbc25f5-c1ea-2234-021e-19841dfd3398@embarqmail.com> <69999145-627b-8c35-85c8-47431dbaaf77@gmail.com> Message-ID: <5843a9f6-5dce-aa99-a6ca-81e59e0e94cc@gmail.com> I would worry about exceeding voltage ratings on capacitors even if it was pre-tuned.

Connect the KX3 to the PX3 with heavy wire (or braid), then connect the KX3 to the KXPA100 with heavy wire - from the KXPA100, connect to the ground rod. You should see a reduction is audio noise on the PX3 (which can be made worse by separate ground wires) and the KXPA100 and KX3 should 'play' better together. If you want more information on bonding, look at the documents produced by Jim Brown K9YC - he posts frequently on this reflector. One thing to keep in mind - grounding everything (the KX3 and PX3 are 'grounded" by virtue of the bonding wires) will not do anything about RF pickup - Mother Earth is not a sink for RF. The grounding is for AC main safety and some protection against lightning and static charges (but not a direct strike). 73, Don W3FPR On 11/27/2018 4:58 PM, richard gilley wrote: > Hi, > Following F.

One comment is that those feedline lengths should be electrical lengths - they will be shorter than the physical length by the amount contributed by the feedline velocity factor. After (or before) that experiment, grab most any good book on antennas and transmission lines, looking with particular interest at the sections dealing with mismatched lines which are directly associated with SWR. 73, Don W3FPR On 11/27/2018 5:51 PM, Michael Walker wrote: > If you truly want to understand SWR, I recommend you pick a frequency and > make up a 1/4, 1/2 and 1 wavelength sections of 50ohm coax. > > Then measure the SWR at those points into various different resistive > loads, like 10, 25, 50, 75, 100, 150 and 200 ohms. > > I think you will find the results very interesting.

When I think about it, it seems pretty obvious that an autotuner could get at least as good a match as a human, and probably faster. We?ve had AI search algorithms for thirty or forty years. The true match can?t be much better than the accuracy of the reflected power bridge. Look at the accuracy of the bridge, make sure the smallest L and C values have a reactance that makes adjustments that small, then use a good algorithm. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) From ghyoungman at gmail.com Tue Nov 27 19:39:28 2018 From: ghyoungman at gmail.com (Grant Youngman) Date: Tue, 27 Nov 2018 19:39:28 -0500 Subject: [Elecraft] Phantom signals In-Reply-To: <8fff7f93-9029-6b54-8fc6-bf79f2aac33d@embarqmail.com> References: <4f658da7-33b3-d310-5575-8fd9604d23dc@comcast.net> <7dda60e2ed721c42dc833f79e10f8ea7@smtp.videotron.ca> <1543359424460-0.post@n2.nabble.com> <8fff7f93-9029-6b54-8fc6-bf79f2aac33d@embarqmail.com> Message-ID: <31701A13-F960-4559-8293-8F81FA02F9BD@gmail.com> I sometimes notice a host of phantoms that follow the tuning, but only when the preamp is off.

I remote in to my station once in a while, and I'm at a big disadvantage on 40 when I need to go on phone.

That would be a good test if you can manage it. The other thing that may help is to bond the K3 to the other gear, following the paths of the IF out coax and also the audio cables. Bond from box to box rather than trying to "ground" everything to a single point (which may cause additional noise pickup.? Use the information on that subject from Jim Brown K9YC. If everything else other than the K3 is plastic cased, bond to BNC connector shells and/or computer I/O connector jackscrews. 73, Don W3FPR On 11/27/2018 9:44 PM, N4ZR wrote: > > Trouble is, my computer supplies N1MM+, including its spectrum > display.

Good question - I am unsure. I have my annual hearing test tomorrow and will ask my audiologist for a spectrum chart for each ear. I have an optional remote that provides bluetooth connection which I use with my iphone. It also has a little plug-in adapter to provide bluetooth connection to any audio source (probably intended for computer soundcard connection). I have not tried it. The hearing aids provide for T-coil connection but I found that not good for my use. Picks up too much magnetic fields and noise.

While the length of transmission line doesn't affect SWR (other than the effect of loss), the impedance at a given SWR does change with line length, and that may cause the indicated SWR to change with some instruments. I wonder if an antenna analyzer, which actually measures impedance, and calculates SWR from that, would do any better. If it measures impedance accurately, it should. 73, Scott K9MA On 11/27/2018 21:34, Wes Stewart wrote: > I fail to see what that will prove.

Also, in September, for the power-up sequence, I successfully used the Utility to put in a banner with my call-sign. The idea today was to get DX-Lab and its WinWarbler connected to the KX3. I had read that the KX3's CW-decoding could be displayed in WinWarbler. But now, I have an issue and I'm not even out of the starting-gate. The Utility's tab "Firmware" shows that wheels are spinning in "Attempting to connect KX3 on port COM3 at ...." using various bit/s speeds. The KX3 is set at 4800 bits/s. So, I used Win10's trouble-shooting and got this message: The error I get is "Prolific USB-to-Serial Comm Port (COM8) has a driver problem." I'm mystified that I see COM3 in one place and COM8 in another. I have no idea what to do next. I was horrified to read that I had a Prolific USB adapter; so much bad press about Prolific.

However, I don't think self fitting would be allowed in the UK, as setting the gain too high can cause unnecessary damage to residual hearing, and many new users would set it too low to be effective. Mobile phones are also not accurately calibrated. The other reason for not allowing self fitting of real hearing aids is that hearing loss can be a warning of more serious things, like brain tumours, and a proper audiologist will refer patients for more detailed investigation if there are hints of that. Also, this is only going to work with open fit aids. You can have just a few sizes of fitting. They do tend to work well for people with age related loss, where most of the loss is in the high frequencies. People with more complex losses require custom made ear moulds, and the most difficult cases actually require aids that change the frequency of the sounds. It looks like Olive only address the easy end of the market. I'm not even sure it would be classified as a hearing aid in the UK (hearing aids are prescription only - RX Only in US terms). I can find none of the technical documentation that I would expect for a normal aid, and, in particular, I can find no graphs showing the performance envelope. It looks like it has something more like an in the ear headphone fitting than the sort of fitting you would expect on a normal hearing aid. It has enough output to damage hearing if used incorrectly. It looks to only have one microphone, and loss of directionality is one of the big problems with using hearing aids. Multiple microphones allow some beam forming. Hearing aid pricing is complex, because the marginal cost of manufacture is quite low, but there are are high R&D costs for the noise reduction and automatic adaptation. A lot of the R&D will be recovered by private buyers paying a large premium for the latest technology (a bit like films take a lot from theatre audiences, but eventually are sold cheaply to TV stations). Also the service costs in prescribing and maintaining can be high. For the NHS these dominate the cost of the physical instruments. -- David Woolley On 28/11/2018 02:48, John Simmons wrote: > A friend of mine told me about the new Olive hearing aids coming from S. > Korea.

It was charged at 12.8V with 1 A limit and the connection to K2 was by a resettable fuse. Keeps > 11V for about half the charge. Never a problem despite travelling across all continents. Very light. But I was always afraid that something would short causing trouble. With batteries with PCB for limits, the risk is far lower.

It arrived in early May this year. It failed in October after 6 months of usage. I?m using the same antennas with the KPA500/KAT500 without issues, as I did for a year before the KPA1500 arrived. My questions: Was the KPA1500 released too early without sufficient testing? Why does the KPA1500 see the antennas differently? I have 2 Buckmaster dipoles and a GAP Vertical which all work well with the KPA500/KAT500. All with low set readings. Is this going to be a recurring problem with this new amp? It cost me an additional $210 to return the amp back to Elecraft under warranty. I haven?t seen any comments from Elecraft about failures and what is being done to address the issues. All my other Elecraft gear has been superb and maybe I?ve been lucky... I?m not the smartest guy on the block and this my first big amp so I?m feeling unsure about my last Elecraft purchase. I appreciate this forum... and the group?s advice and feedback.

But I still contend that, with a lossless line anyway, the impedance of a load, resistive or otherwise, is the same at either end of a 1/2 wavelength line, or integer multiple thereof.? A quarter-wavelength line has the "magical" property of inverting impedances, best seen on a Smith chart.? But the rotation is around a circle of constant SWR, with radius=rho. Of course better instruments as a rule make better (more accurate) measurements.? I have several vector analyzers, an N2PK that I built years ago, an SDR-Kits by DG8SAQ, an FA-VA5 by DG5MK, an AA-55 Zoom by Rig Expert and if it ever clears US Customs, an FAA-450 by EU1KY.? Any of these, used with appropriate care, is more than accurate enough for any normal transmission line/antenna evaluation and remarkably inexpensive. Wes?

The nice thing about using the KX2 battery is that it plugs into the power jack in the back of the K2 - no need to mount it inside. Get the charger from Elecraft and you can unplug the battery and charge it without opening the K2. 73, Don W3FPR On 11/28/2018 11:53 AM, John Harper wrote: > Isn't this essentially a KX2 battery (ie, same cell type & number of cells)? > > John AE5X > https://ae5x.blogspot.com > ________________________ > > But I would choose > Li-Ion something with less max current and PCB board for safety and > reliability.

The new version makes changes in the digital format of FT8 and MSK144 that make it INCOMPATIBLE with older versions. The changes have been made to allow a few more characters to be transmitted, to allow for /R to indicate Rovers, to allow for contest exchanges for Field Day, RTTY Roundup, and VHF contests, and to allow for more complex and non-standard callsigns. V 2.0 also includes better error checking, resulting in fewer false decodes, and it eliminates the grid wierdness that occurred in V 1.9 when one station was using Contest Mode and the other was not.. While V 2.0 is currently in Beta, it's well-advanced beta, and works very well. Those using 1.9 cannot copy or transmit to stations using V 2.0 and those using the latest V 2.0 betas cannot copy stations using V 1.9. The non-beta release of 2.0 is scheduled for Dec 10. (Early 2.0 beta versions DID allow 1.9 and 2.0 users to communicate, but this capability has been removed to allow the final version to work better.) Users are encouraged to switch to the new version as soon as possible. The only downside is that most users are still using V 1.9, so you won't be able to work them, but this will gradually change as more users upgrade, and the transition will happen more quickly as more users upgrade. K1JT's Quick-Start Guide is here. https://physics.princeton.edu/pulsar/k1jt/Quick_Start_WSJT-X_2.0.pdf Links to installation packages are here. https://physics.princeton.edu/pulsar/k1jt/wsjtx.html 73, Jim K9YC From eckerpw at gmail.com Wed Nov 28 15:39:09 2018 From: eckerpw at gmail.com (Paul Ecker) Date: Wed, 28 Nov 2018 15:39:09 -0500 Subject: [Elecraft] For Sale P3 with SVGA, TX Monitor Message-ID: The P3 has been Sold.

This is a "mock" contest. The 2nd one - also a mock test - is this Friday evening (NA time) from 0200-0300Z. Both of the above test contests will take place on 7078 and 14.078 kHz and require thus use of either -rc4 or -rc5 although -rc5 is preferred as it i sexpected to be the final beta version before the finished V2 is released in mid-December. These versions allow for the contest exchange used in the RTTY Roundup.

I installed v2.0.0-rc4 which locks you into 77 bit messages and found very little decode action on my waterfall so I reverted to v2.0.0-rc3. It is advised that -rv3 cannot be used after 30 November. Is it software bombed and will stop working, time will tell. I have downloaded rc5 but as yet haven't bothered to install it and might just pass over it to the general release v2 when I feel it's worth doing.

Message-ID: Hello All, I have a K3 and a K3/0 mini control head. They are both mounted with the front panel vertical in my shack. That's the natural way the K3 sits, but not the K3/0 mini. The K3/0 mini is designed for use primarily in a portable setting with the display at a shallow angle to the desktop. My problem is the K3/0 mini display is quite washed out in the vertical position even with the LCD Adjust Menu entry set to 100. At the minimum setting of 2 the display is virtually blank when viewed directly on at eye level. Does anyone know of a "Super LCD Adjust" menu setting that will override the design tendency of the K3/0 mini to only be used at shallow angles on a desktop rather than at eye level?

I had my annual hearing test today. I asked for a chart and out of curiosity we looked back to my first exam in 1996 which resulted initially getting hearing aids. Apparently little change but my audiologist remarked that i had significant loss even back then at age 52. I will summarize the chart L-ear/R-ear: 250-1000 Hz -55 dB 1000-1500 Hz -60/65 dB 1500-3000 Hz -80/70 dB 3000-4000 Hz -80/80 dB >4000 Hz -110 dB/95 dB Equipment unable to produce sounds that I can detect - essentially deaf above 4-KHz. testing speech recognition without hearing aids I get about 50% understanding - mostly via right earl My hearings are 22-ch A/D and we made some radical adjustments including a feature that translated some sounds at high freq to a lower freq where I have better hearing. Anti-feedback is right on margin which would explain sensitivity to the CM500 headset. She made several adjustments to equalize my hearing for each ear. Really works much better so will be interested to see how that affects hearing weak-signals (aka eme signals). Probably a good point to end this discussion on the list.

Contributing to the development of FREE software that we use is a bad thing? WSJT-X is a voluntary effort by a group of hams who are proficient at programming. Simply by using the new software we make QSOs with other hams who are also using it, we are contributing. Since my earliest days in ham radio (I was 14) other hams taught me CW, electronics, radio, and how to operate. One gave me my first rig, another taught me the fundamentals of contesting. Ham radio has always had a tradition of of individual hams contributing what they can based on their capabilities. I've watched W6OAT do a wonderful job of warmly mentoring a prospective ham at the GOTA station on Field Day. Testing beta software is a contribution. I contribute by doing research on technical issues that matter to hams and publishing it, FOR FREE. Mamy of the folks who make the greatest contributions to ham radio don't ask for money, but they really hope that others will do their part. Among them are AC6LA, the author of great spreadsheets that run in Excel to do tricks with antennas and transmission lines, AE6TY, who wrote the wonderful SimsSmith software, AA6YQ, author of the wonderful DXLabs suite that includes DXKeeper, and the team that produces the N1MM contest logger. And there are the thousands of hams who contribute to EmComm, to mentoring new hams, to teaching license classes, to helping other hams with computers, antennas, and so on. This is a chance for all of us to help out the WSJT-X team. All of this stuff is GREAT software, and it's FREE. The least we can do is using their beta software! 73, Jim K9YC From lightdazzled at gmail.com Thu Nov 29 10:30:22 2018 From: lightdazzled at gmail.com (Chip Stratton) Date: Thu, 29 Nov 2018 10:30:22 -0500 Subject: [Elecraft] PROPOSAL: K2/10 Battery LiPO / 8AA carrier option In-Reply-To: <1543422838178-0.post@n2.nabble.com> References: <708740531.3441458.1543338490180@mail.yahoo.com> <1701215562.112532.1543383705628@mail.yahoo.com> <1543422838178-0.post@n2.nabble.com> Message-ID: I think you would be much better off with a 4S LiFePO4 instead of a 3S LiPO. Your fully charged voltage would be just under 14 volts, and fully discharged around 12 volts. I once found a 4S LiFePO4 battery on Ebay that was almost exactly the same size as the SLAB that the K2 battery kit included, and fit inside the K2 using the existing battery strap. It worked very well, even using the original charging circuit. Although it had a balance connector, I found that the cells were never significantly out of balance using the K2 charging circuit. I made a point not to leave it plugged in to the mains power supply once the battery was fully charged, but LiFePO4 in my experience tolerates overcharging time at low currents rather well, unlike regular LiPO. Having said all that, YMMV and it is always best to balance charge any Li rechargeable battery with an appropriate balancing charger and away from the radio or potentially flammable materials, etc. etc. etc. Chip AE5KA On Wed, Nov 28, 2018 at 11:37 AM Ignacy wrote: > This battery has very high current potential but does not have a limiting > board.

Of course helping test Open Source software is a good thing, but there is a certain technical sophistication that is needed by users to make trouble reports that are meaningful to the developers. It also requires closely following the WSJT-X group to be aware of what is going on in the development process. I would guess that most WJST-X users are interested in using the software to make QSOs. Some of you are probably aware that the FT8 data frame is being modified from the current 75 bit frame to a 77 bit frame in the 2.0.0-rc release candidates causing versions >= rc-4 to be inoperable with 1.9.1. This is causing no end of confusion for people using the release candidate versions but who are not really up on what is going on with the new development. So, IMHO, those who are interested enough in the development process are helping with testing the release candidate versions and those who are not should just enjoy 1.9.1 until the 2.0.0 version is released. There are a lot of people testing the rc's so it isn't really a problem. 73, Steve K6ZX From KX3.2 at ColdRocksHotBrooms.com Thu Nov 29 14:27:41 2018 From: KX3.2 at ColdRocksHotBrooms.com (Lynn W.

Even though the changes were minor, a few other functions were updated for esoteric reasons having to do with "the linker," etc., that I won't bother you with. However, because of this, we need to do a full re-test (all bands, all modes, all features). The best way to make sure we've covered all the bases is to send the code out to a lot of testers as a field-test release. If you're available to load and test this code (just doing normal operation) between now and Monday, please contact me directly. Thanks!

I have no interest in how good any Elecraft tuner is at finding a minimum SWR solution. I use my LP-100A which will give good complex load readings with far lower power output that is required for the KAT500 to give a much less useful SWR reading. None of my tuning solutions was derived by the KAT500. It can't find a solution with the 5 W signal I like to tune with. As to your assertion that an SWR of 2:1 should be tolerable I call "bollocks!" The KPA500 will not even accept 1.5:1 if the R is on the low side of 50 ohm. SWR is a poor indicator of the load presented to an amplifier. I was perfectly happy with an SWR of 1.5:1 until I started using my KPA500 and realized the very significant difference the complex load made to PA dissipation and the probability of fault trips. I use my KAT500 as a manual tuner and just wish it would do what I tell it. (I found a solution for this frequency, I gave it the frequency, use the solution I told it to use for that frequency.)

An SWR of 1.4:1 can cause it to fault well below 1500 W due to either excess current or excessive drive power, or to greatly exceed 1500 W output.

I've carefully "trained" my KAT500 all across the 160 meter band. Since the manual states that the tuning bins are 10 kHz wide below 3 MHz, I do a tune at 1805, 1815 ... up to about 1895. My antenna is an impossible load above 1900 kHz, so I don't try to tune up there. Since I don't have exactly a great antenna system, I almost always stick to S&P operation in 160 meter contests. As I tune across the band I can hear the relays selecting the appropriate tuning solutions. But... every once in awhile, as soon as I key the transmitter I hear the relays in the KAT500 switch, presumably out of the commanded tuning bin due to frequency measurement error in the RF detection circuit. This shouldn't be a problem, since the tuning doesn't change significantly between adjacent bins. However, since the amp is being keyed while the tuner is changing presets, the amp immediately faults and goes off line. This is very annoying, and probably not so good for either the amp or the tuner. If the RF measurement resolution is really as poor as 8kHz, I don't see why there's any point in providing for 10 kHz wide tuning bins on the low bands. I would also strongly agree that if good frequency information is available to the tuner via the serial bus that's what it should use to select tuning bins. The RF sensing information should be a backup source, to be relied on only in the absence of such data. 73...

Although, I prefer not to operate in that configuration if not necessary. I think in general we fret too much over values of SWR which are 1.5:1 or less at the station end i.e. between the tuner and the amp or transceiver.? This is? without regard to the actual SWR on the feedline between the tuner and the antenna load.? That is where the real power loss occurs.? Also, in many cases, using a tuner in a feedline where the SWR is 1.5:1 or less, most likely the tuner introduces more loss than if the tuner was not in the path.??? There is a nice XLS spreadsheet http://www.dj0ip.de/antenna-matchboxes/matchbox-shoot-out/ showing the actual loss of many different tuners, different bands, and different matched and unmatched losses.?? Rather eye opening. Regarding the SWR fault at 1.4:1, is that at 35 ohms or at 70 ohms??? Significant difference in current demand of the PA between the two values while SWR appears to remain the same.?? This is largely the reason I often state that SWR only tells 1/2 of the story of antenna system performance.? A PA correctly designed will monitor the current in addition to SWR? and not just SWR as most seem to do. 73 Bob, K4TAX On 11/29/2018 6:16 PM, K9MA wrote: > > That certainly is not the case with the KPA1500.

That 2:1 SWR can be anywhere from 25 to 100 Ohms, plus various reactive impedances in between. On simple-minded way to look at it is to imagine an amplifier as a low-impedance source. (A crude approximation, but a useful one.) With the same drive level, it might deliver 200 W to a 25 Ohm load, or 50 W to a 100 Ohm load.? If you reduced the drive to the 25 Ohm load for 100 W output, the amplifier would be very inefficient, as current would be high. On the other hand, if you increase drive with the 100 Ohm load, it is likely the amplifier will saturate before reaching full power, due to limited voltage output capability.? The only way to make an amplifier tolerate such big load differences is to make it capable of much higher output, which increases cost. A good ATU is probably more cost effective. 73, Scott K9MA On 11/29/2018 19:22, Bob McGraw K4TAX wrote: > In checking my K3S into an antenna that presents a 2:1 SWR as > indicated on my external Power/SWR meter, my KPA500 in STBY, and my > KAT500 in bypass mode, it does deliver 100 watts.??

I paid a lot less attention to the SWR that my Titan 425 amps saw because their manually tuned Pi-Li output stage could make the tubes happy working into much higher SWR than the auto-tuned Pi-L in the 87As that replaced the Titans. And they both use the same tubes. The Alpha will fault as the SWR approaches 2:1.? And, has been noted, both KPA amps introduce loss in the drive circuit to reduce power if the SWR gets too high because it makes the output devices too warm. > This is? without regard to the actual SWR on the feedline between the > tuner and the antenna load.? That is where the real power loss occurs. Yes and no -- most hams believe that excess loss due to SWR is much higher than it is. I got into this many years ago when specifying low loss 75 ohm CATV coax for remotely located wireless mic antennas for sound systems in large spaces. Engineers for the major wireless system mfrs told me that 1) they didn't know what the input Z of their receivers were and 2) that was probably somewhere between 50 and 100 ohms. My logic was (and still is) pretty simple -- thanks to the very high volume of coax for CATV systems, low loss 75 ohm coax is FAR cheaper than low loss 50 ohm coax, and even assuming a 50 ohm RX input, worst case excess loss for a 1.5:1 mismatch is 0.18 dB no matter how long the line is. That said, because the bandwidth of 80M is a rather percentage of its operating frequency, SWR can get fairly high at the band edges of a dipole cut to the center of the band. My dipoles are up about 120 ft at the end of about 170 ft of coax with feedpoint Z are resonance about 88 ohms (measured), so they're fed with the lowest loss RG11 I can find (currently Davis RF RG11, which measures like Belden 8213). > Also, in many cases, using a tuner in a feedline where the SWR is > 1.5:1 or less, most likely the tuner introduces more loss than if the > tuner was not in the path.???

Rather eye opening. Nice chart, which I've seen before. Over the years, ARRL has published this sort of testing for a lot of tuners.? I'd far rather see this in dB -- 10% lost power is 0.46 dB, 20% is 0.97 dB. 73, Jim K9YC From donwilh at embarqmail.com Thu Nov 29 21:48:24 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Thu, 29 Nov 2018 21:48:24 -0500 Subject: [Elecraft] KPA-1500 issues In-Reply-To: <7b6d58ff-8e1b-6f74-d27d-5aa15ac137a2@tx.rr.com> References: <7b6d58ff-8e1b-6f74-d27d-5aa15ac137a2@tx.rr.com> Message-ID: <2d10521d-b15d-1749-c4db-e288ca7bd630@embarqmail.com> Randy, That indicates that you do not have your KAT500 and amplifier properly connected.

The tuner should be "trained" to the antenna(s) in AUTO and then placed in MAN for operation. That will prevent the ATU from attempting to tune when it falsely detects a high SWR - usually only happens with SSB operation, or frequency sensing of a frequency where the ATU has not been "trained" to store the L/C values appropriate to the antenna selected. 73, Don W3FPR On 11/29/2018 9:16 PM, Bill Johnson wrote: > And a poor antenna system cannot be "fixed" by any a antenna tuner, > especially an? automatic one.?

If it is happening to you it suggests that you are not running the amp keying line though the KAT500, or the KAT500 is not performing as intended. The interrupt is monitored by the KAT500 utiliity but the update rate is too slow to catch a typical keying interrupt.

If you are running a tube amplifier that requires tuning, and the tuner always provides the identical load, you can tune the amplifier once, record the dial settings, and quickly reset the amplifier tuning "by the numbers" when you change bands. But even a small change in load impedance might require manual touch-up of the amp tuning. So it is nice to be able to preset the tuner exactly.

Like most mechanical components, there is a wearout time, but I suspect it is in the vicinity of 1000 to 5000 hours. That is a lot of operating time. If you are concerned about wearout, just turn the KPA off (or standby) when not using it. 73, Don W3FPR On 11/30/2018 10:30 AM, Monkeys wrote: > Is there any harm in setting the fan at level 2 and just leaving it > there?

In reply to this post by Bob McGraw - K4TAX I would be surprised if two garden variety instruments, even placed at the same point, would agree. The directional bridges/couplers in most "(V)SWR" meters that hams routinely use externally or which are built into our radios are not precision instruments. There are a number of error sources in reflection measurements; source match, diode non-linearity, coupler tracking errors and often the most significant, directivity error. In an ideal coupler, (i.e signal separation device) one port measures the forward (incident signal) and another measures the reverse (reflected) signal and there is no coupling between ports in the unwanted direction(s). In other words there is no signal at the reverse port due to the forward signal. In a real world coupler there is some leakage signal appearing at the reverse port due to the forward signal, absent any reflected signal. The "goodness" of a directional coupler in this instance is called "directivity" and the error signal is directivity error. Directivity is usually specified in dB. Really good couplers might have directivities in the 40 dB neighborhood. Really really good directional bridges can be 50 dB, but so-so units might be 25-30 dB. Not ready for prime time units are lower than this. Now I have no way of knowing what the directivities are of the couplers built into K3s, KPA500s, KAT500s, etc. but considering that they have to work over about 5 octaves, I'm going out on a limb and saying that 25 to 30 dB is a fair estimate. If I'm wrong, I'm sure I'll hear about it. For sake of discussion I'm going to use 26.5 dB. What this means is that if I terminate the output spigot of one of these radios with a perfect 50+j0 load, I'm going to measure a leakage signal (directivity error) that is 26.5 dB below the incident value. I'll introduce the concept of return loss here. We hams usually speak in terms of SWR. SWR = (1 + p) / (1 - p) where p is the reflection coefficient. Here the p = the voltage measured at the reflected port and the constant 1 represents the incident signal. In reality both of these quantities are complex numbers, they have both magnitude and phase but SWR measurements are scalar, we throw away the phase (since it's difficult to measure) and just use the magnitude. (In fact the symbol "p", which is really the Greek letter rho, indicates the magnitude of the reflection coefficient in normal usage) We can also express this ratio as return loss, which is -20 * log10(p). So return loss, SWR and reflection coefficient are just different ways to express the same thing; the ratio of incident to reflected signal. Let's return to our example; the coupler with 26.5 dB directivity, which indicates a return loss (RL) of 26.5 dB even with a perfect termination. Doing the math and converting RL = 26.5 dB to SWR we get 1.1:1. Our perfect load measures 1.1:1 with our imperfect instrument. And this assumes that there are no other errors, which there always are. But it gets worse. Let's say that the load we want to measure really is 1.1:1. We now have two (apparent) reflections, 1) the real one and 2) the directivity error and they both have the same magnitude. In our simple detector, they sum together. Now I said earlier that we don't measure phase, only magnitude, but just because we don't, or can't measure the relative phases doesn't mean they aren't there. We will examine two cases to determine the limits of error. Case 1) both reflections are in phase, they add up to p + p or 2p, RL = 20.5 and SWR ~1.21:1. Case 2) they are exactly out of phase, they sum to zero. p = 0, RL is infinite and SWR = 1:1. The possible RL error is then -6 to +infinity dB! In other words, an actual SWR of 1.1:1 can be measured anywhere between 1.0:1 and 1.2:1. Is it any wonder that we often read about concerns that one device measures one thing, while another located at the same, or close location measures something different. Of course all of this is predicated on a directional coupler with 26.5 dB directivity and no other error sources. It's entirely possible that the Elecraft couplers are better than this. They are certainly no better than 40 dB since the internal reference resistors are 51 instead of 50 ohm. Plus the "Tandem Match" configuration is in itself not a great match to the transmitter output.(1) Furthermore, the coupler, at least in a K3 is driven by a LPF, which isn't a great 50 ohm source. Plus the coupler output port isn't connected directly to the coax connector..... and so on and so forth (2). All of this creates "uncertainty." In a metrology lab heroic efforts are made to reduce uncertainty but do we, or should we, really care in this situation? In my opinion, no, but everyone is free to differ.

Precision can be accomplished by adding the extra digits, but the accuracy of the instrument will tell you how many of those extra digits are to be considered. Most digital voltmeters, even the cheap or free ones from Harbor Freight and others are surprisingly accurate (5% or so is common), but typical voltage readings of 3 significant digits are reasonable but any digits more than that are extraneous unless the instrument is of lab quality. 73, Don W3FPR On 11/30/2018 11:12 AM, Charlie T wrote: > Yep, ur right Don.

The professor used the example of bullet holes in a target. If the holes were closely spaced, but far from the bulls-eye, the shooter was inaccurate but precise. If the holes were widely spaced, but the average was near the bulls-eye the shooter was accurate but imprecise. Closely spaced on the bulls-eye precise and accurate Widely spaced, and the average not near the bulls-eye, imprecise and inaccurate. Easy to remember. Some other memorable nuggets from that class: Evaporation is a cooling process. High octane gasoline is slow-burning gasoline.

For instance an instrument that is accurate to 5% and has a 4 digit display can show us (when measuring a 5 volt source) anywhere between 4.750 volts and 5.250 volts and still be within the 5% accuracy window for the instrument. Review the specs and calibration for whatever meter you are using and do not expect those extra digits to be correct - in other words round the numbers displayed. Many wattmeters are only accurate to 20% of the reading - so if one wattmeter at 100 watts shows 120 watts and another shows 80 watts, the actual power could be 100 watts. Take that into consideration. The Telepost LP-100 when calibrated to NIST standards is accurate to 5% (it can be lower, but Larry will not guarantee it). So any power it displays between 95 and 105 watts can actually be 100 watts. In other words, look at the specified accuracy of whatever meter you are using and take that into consideration.

There are instructions for doing so in the operating manual. It's kind of interesting to see how it appears on the P3, though. The spurious will tune across in reverse directions from normal signals, and usually at double speed. If you've notched it out of your receiver (the procedure jiggles the synthesizer frequencies a bit in the immediate area of your receiver passband) you will see it approach your receiver passband on the display and then magically disappear as it crosses your passband cursor. It will then re-appear on the other side. Pretty interesting effect, but perfectly logical, once you understand what is being done 'under the covers' to prevent you hearing that birdie in your receiver. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] P3 Phantom Signals From: Keith Onishi Date: Thu, November 29, 2018 11:43 pm To: Elecraft I have the same on my P3.

A little bit of trial and error with the amp on on 160 meters shows that the intermittent high VSWR faults I was encountering were due to a "feature" of my antenna system. Apparently there is water in the FCP transformer box or a bad coax cable that was causing an intermittent arc or other breakdown at high power. The problem is much worse at the high end of the band, where the antenna VSWR is higher (imagine that!). All of this led me to spend a couple of hours investigating what the KAT500 was actually doing on 160 meters. It turns out that, despite what the manual says, the tuning bins on 160, and presumably everywhere below 3 MHz, are actually 8 kHz wide, not 10 kHz. This was verified by slowly tuning the radio and listening to the presets changing. My 160 antenna has a VSWR that changes rapidly enough as a function of frequency that most every bin had a slightly different tuning solution. This made it possible to see the bin boundaries across most of the band. The bins start at 1800 kHz and are spaced exactly every 8 kHz. Tuning slowly with fine tuning engaged it can be seen that, for example, when the radio is tuned from 1807.999 to 1808.000 kHz the KAT will change to the next preset. I re-trained the tuner by tuning to the center of each bin: 1804, 1812, 1816... all across the band and executing a "Tune" operation at each frequency. I had always wondered why the KAT utility reported frequency values that were frequently quite different from the actual transmit frequency. It turns out that the "Observed Frequency" value displayed in the utility Operate window is the low end of the particular tuning bin that has been selected by the selection algorithm. 1836 reports as 1832, for example. Since my antennas for 80 meters and higher are not extremely high Q, it would be difficult to do a similar experiment to determine what the actual tuning bin widths are on the higher frequency ranges. I realize this behavior may be of academic interest only, since the firmware does seem to do a good job of selecting the appropriate tuning solution, but for a very high Q antenna such as is frequently found on 160 and/or highly compromised shortened antennas for other HF bands it could be important. It would be nice if the Elecraft folks would correct the manual to show what the actual tuning bin widths are for each range. 73...

It turns out that the "Observed Frequency" value displayed in the utility Operate window is the low end of the particular tuning bin that has been selected by the selection algorithm. " I don't think that is correct. From my experimental observations I believe the last observed frequency (the value returned by the F; interrogation) is the most recent value of F received over the serial interface unless that value has been changed to a more recent RF detected frequency. RF detected frequency has a resolution of 8 kHz which may or may not match the size of a tuning segment. (There is an exception to this though - If the last value of F received over the serial interface caused a KAT500 band change then the last observed frequency will be stuck at zero until another F transmission is made or until an RF transmission is made . This anomaly has been reported to Elecraft and it's "on the list") The behavior of last observed frequency does not change if the KAT500 is in bypass mode where no tuning solution is being selected. it is my understanding that the KAT500, when connected to a K3, actually tracks the K3 receive frequency not the transmit frequency. My TS-590 Elecraft interface gives the KAT500 the calculated transmit frequency not the receive frequency which seems to me to be a better implementation. ( I had enough problems with my SteppIR retuning at the start of a split TX to want to play the same games with my KAT500 and KPA500) Andy, k3wyc From nr4c at widomaker.com Fri Nov 30 16:02:00 2018 From: nr4c at widomaker.com (Nr4c) Date: Fri, 30 Nov 2018 16:02:00 -0500 Subject: [Elecraft] External AMP In-Reply-To: <3E86C9D6-3916-4C0F-9297-E5EF6BE5E9C2@gmail.com> References: <3E86C9D6-3916-4C0F-9297-E5EF6BE5E9C2@gmail.com> Message-ID: <9483333A-DA38-476F-9D84-22EDFD227BC4@widomaker.com> How many Amps does it draw?

I would bet that once in a while you will find two adjacent frequency segments that fall in the same bin, and no change occurs. I also suspect that the RF frequency count resolution is 8 KHz (as it is in the KPA500), which will show similar frequencies when transmitting. When operating the KAT500 with the K3/K3S, we usually have the K3 tell the KAT its current frequency, which is why it switches during receive and on 8 KHz boundaries. I sympathize with you on the water issues. We see a lot of that kind of problem. My ?favorite? is the right-angle coax adapter (this one bit me). The cheaper ones do a poor job of constraining the inner conductor, and at high power will arc to ground. I changed out all my adapters for good ones (read: more expensive), and no longer have the issue. Figuring out the problem is usually rather difficult since you can?t actually see the arc results because they are inside an enclosure. You are lucky to find your issue so easily, but then water intrusion is a bit more obvious. As far as calculating bin size, I suspect that K3WYC?s solution of sending FA; response frequencies into the KAT500?s serial port might actually yield a better solution since those frequencies can have 1KHz (or better) resolution. In this case the relays should switch very close to the actual boundary instead of at 8KHz boundaries. What I don?t know is if the KAT500 uses RF counted frequency for its bin determination or if it can use the externally reported frequency. I suspect it is the former. Glad you found the issue. Perhaps you now might find a way to lower the antenna Q to require fewer bins (and perhaps wider bandwidth), but it is good to know the KAT is providing a solution for your antenna the way it is (well, without the water). 73!

A little bit of trial and error with the amp on on 160 meters shows that the intermittent high VSWR faults I was encountering were due to a "feature" of my antenna system. Apparently there is water in the FCP transformer box or a bad coax cable that was causing an intermittent arc or other breakdown at high power. The problem is much worse at the high end of the band, where the antenna VSWR is higher (imagine that!). > > All of this led me to spend a couple of hours investigating what the KAT500 was actually doing on 160 meters. It turns out that, despite what the manual says, the tuning bins on 160, and presumably everywhere below 3 MHz, are actually 8 kHz wide, not 10 kHz. This was verified by slowly tuning the radio and listening to the presets changing. My 160 antenna has a VSWR that changes rapidly enough as a function of frequency that most every bin had a slightly different tuning solution. This made it possible to see the bin boundaries across most of the band. The bins start at 1800 kHz and are spaced exactly every 8 kHz. Tuning slowly with fine tuning engaged it can be seen that, for example, when the radio is tuned from 1807.999 to 1808.000 kHz the KAT will change to the next preset. I re-trained the tuner by tuning to the center of each bin: 1804, 1812, 1816... all across the band and executing a "Tune" operation at each frequency. > > I had always wondered why the KAT utility reported frequency values that were frequently quite different from the actual transmit frequency. It turns out that the "Observed Frequency" value displayed in the utility Operate window is the low end of the particular tuning bin that has been selected by the selection algorithm. 1836 reports as 1832, for example. Since my antennas for 80 meters and higher are not extremely high Q, it would be difficult to do a similar experiment to determine what the actual tuning bin widths are on the higher frequency ranges. > > I realize this behavior may be of academic interest only, since the firmware does seem to do a good job of selecting the appropriate tuning solution, but for a very high Q antenna such as is frequently found on 160 and/or highly compromised shortened antennas for other HF bands it could be important. It would be nice if the Elecraft folks would correct the manual to show what the actual tuning bin widths are for each range. > > 73... > Randy, W8FN > >> On 11/29/2018 8:48 PM, Don Wilhelm wrote: >>> Randy, >>> >>> That indicates that you do not have your KAT500 and amplifier properly connected. >>> >>> The KEYOUT line from the transceiver should go first to the KAT500, and then from the KAT500 to the amplifier. >>> When the KAT500 needs to tune, the amplifier will not be keyed and tuning will take place at the power output of the transceiver. >>> After tuning, the amplifier will be engaged. >>> >>> 73, >>> Don W3FPR > > ______________________________________________________________ > 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 jackbrindle at me.com From jackbrindle at me.com Fri Nov 30 16:11:46 2018 From: jackbrindle at me.com (Jack Brindle) Date: Fri, 30 Nov 2018 13:11:46 -0800 Subject: [Elecraft] External AMP In-Reply-To: <3E86C9D6-3916-4C0F-9297-E5EF6BE5E9C2@gmail.com> References: <3E86C9D6-3916-4C0F-9297-E5EF6BE5E9C2@gmail.com> Message-ID: <63357469-D87E-4890-A97B-9A5EAC22DEA8@me.com> No. There is no power source in the ACC connector from the K3.

What I don?t know is if the KAT500 uses RF counted frequency for its bin determination or if it can use the externally reported frequency. I suspect it is the former." Not quite how I implemented the frequency interface. What I do is use the values of IF, FA , and FB to determine the frequency my TS-590 would transmit on if it went into TX at that instant. This calculation to done each time I get a new value of IF, or FA, or FB. I send that frequency value to the KAT500 using the F command but I only send it if the calculated transmit frequency differs from the KAT500 last observed frequency by more than 8 kHz. Sending the raw FA value to the KAT500 is not a useful solution for several reasons - The TS-590 may not be using VFO A for RX or TX; if the TS-590 is using VFO A then FA alone is not enough information to know if A is the TX or RX VFO for split; Even if A is the TX VFO, FA does not include XIT offset; FA is not meaningful for memory channel operation; etc. ) The KAT500 follows the TX frequency I send it and sets the proper tuning solution for that frequency with no RF transmission required. The only issue with my implementation is that RF detection can override the frequency I provided and move it to an adjacent, incorrect or less accurate, value. The fact that the last observed frequency is changed by RF does not necessarily mean a new tuning solution will be selected. That depends on how the 8 kHz increments of last observed frequency overlay the tuning segment boundaries (and other factors that are likely Elecraft proprietary). 73, Andy k3wyc From kt3y at aol.com Fri Nov 30 17:50:11 2018 From: kt3y at aol.com (pca) Date: Fri, 30 Nov 2018 18:50:11 -0400 Subject: [Elecraft] K3 power level question Message-ID: <9F4DD0F7-55F3-4B86-9D1F-F8BF37AF551C@aol.com> Is there a way to limit a K3 to, for example, 25 watts via it?s firmware.
