The power meter uses a series Schottky diode detector. The low reasonable resolution is about 0.3 VDC, or 0.3 * .707 = 0.21 Vrms out of the directional coupler. The Power for 0.21 Vrms is: 0.21^2 / 50 = .88 mW Assuming a 20 dB coupler 1:10 turns ratio, 0.88mW * 100 = 0.88W reflected power. Assuming forward power of 100 watts and 0.88 watt reflected power the return loss is: 10 * log(100 / 0.88) = 20.6 dB Using the calculator: https://www.allaboutcircuits.com/tools/vswr-return-loss-calculator/ 20.6 dB Return Loss computes to VSWR = 1.222 Therefore, the best lowest estimated K3 VSWR, assuming a 20 dB coupler, is about 1.2. Check my numbers. John KN5L On 7/27/18 9:58 AM, Dick Dickinson wrote: > I've noticed that I'm not showing a reading of less than 1.1:1 SWR on my > antennas per K3 SWR Numerical Readout.

Question answered, wsjtx FT8 v2.0.0-rc3 which the launch pop-up indicates cannot be used after 30 Nov is correct. It has ceased to run, blown up! Now the question is do I bite the bullet and install v2.0.0-rc5 and emulate my neighbour who spends a lot of time calling CQ and getting very little action with 77-bit messages or do I revert to v1.9.1 and continue to have plenty of action? For now v1.9.1 wins. I don't have the time to waste unnecessarily achieving so little. My beam is currently stuck pointing up the Americas, South, Central, North including VE and KL. Consequently I've been working on FT8 mode/band WAS as well as handing out grid GD18 which I confirm immediately via LoTW after I QRT from a run. December is a new month in the ARRL Grid Challenge and it seems a bizarre thing to do to try and force fundamental mode changes at this late stage of the activity. FWIW I have made WAS FT8 mixed band and 17m single band pending a confirmation of HI. 15m and 12m are not too far behind. In this quest my much upgraded K3 #00345 has performed flawlessly and continues to do so whilst running the current pre Beta 5.66 test firmware.

When the amp is in "standby" the fan would be under normal temperature control. This has the secondary benefit that blind operators would then have a way to distinguish between operate and standby which cannot be done presently.

You?re on the right track with changing the coax. You have some sort of resistive loss. As you note, the ?bandwidth? is much higher than it should be. My inverted L had a 2:1 SWR bandwidth of perhaps 35 KHz at most. Your low SWR across the entire band indicates very low efficiency and some sort of loss element(s). After the coax, I?d look at connectors, insulators, etc. etc. Do you have any feed-thrus, suppressors, or other things in the feed system? I?d suggest first checking the SWR and bandwidth right at the antenna base with the coax disconnected. Use a portable instrument.

Yes, the antenna appears to be resonant below 1.8 MHz. An inverted L consists of two parts, both equally important -- the vertical with the horizontal top, and the counterpoise/radial system.

That should tell you what the antenna itself reads both for resonance and SWR. Then put a dummy load on the antenna end of the coax. Most antenna analyzers are capable of measuring the coax loss, so go into the shack at the other end of the coax and measure it. Those two steps will tell you whether the problem is with the antenna or the feedline. If you do not have a coax loss function on your antenna analyzer, feed the coax, put a wattmeter in the coax in the shack and observe the power. Without changing anything on the rig, remove the wattmeter and move it to the other end of the feedline. Have someone else do a TUNE on the rig while you observe the power at the other end of the coax - compare the two wattmeter readings. If nothing is revealed by those tests, look with close scrutiny at any coax connectors or adapters that you did not use for the tests - adapters are a frequent cause of failure - lesson to use only good ones. 73, Don W3FPR On 12/1/2018 11:54 AM, Leroy Buller wrote: > There > I tried to get on 160 with my Inverted L last night. 60 feet up and the > rest over to a tree, 130 feet total.

The resonant point appears to be well below 1.8 MHz and there is clearly a lot of loss in there somewhere. He says he changed out the coax so water in the coax seems less likely. The fact that the resonance has dropped is odd, since it implies more length instead of less like you'd get with a bad connection. I wonder if the end of the wire that is in the tree has lost it's insulation and there is actually contact to wet wood there.

There are stations in groups in a number of places on the band. The P3/PX3 sure comes in handy going between them. Using the markers you can easily mark a group with marker A and tune to them, and go back easily, because you can see the FT8 groups easily. ??? Has anyone else come up with any operating tips?????This is the first time, I think, we have experienced the use of different frequencies on the same band.Now we need a MAP65 program that will read the whole band.

I?m not an electronically educated fellow, merely just seeking the practical. A resolution to my post was provided in the suggestion that the apparent 1.1:1 SWR might be the result of common mode current. Sure enough when I installed a 1:1 current balun at the feed point of the antennas (2 perpendicular Inverted Vees with a switchable common feed point), the value went from 1.1:1 to 1.0:1 and the bottom of the SWR curves which also broadened out. Still that doesn?t explain why the K3 was showing 1.1:1 while passing 1.0:1 information to K3EZ, or so it seems. I don?t think that the K3EZ is ?measuring SWR? rather merely posting information it is getting from the K3 no different measuring device or location. Perhaps it is a sort of ?rounding error.? By the way, for those who haven?t come across it, K3EZ has the great feature of being able to step the K3 across a frequency range, momentarily key it, step again, etc. and plot in text an SWR chart a handy feature for working with an antenna installation. Following is a situation that perhaps you have the theoretical background to explain I have a full-size monoband vertical for 40 meters. Simple architectural aluminum tapering from 1 ?? (?) in 6? telescoping sections. The radial field is designed to provide a 50 ohm match at the feed point 12 ? 13?+ radials. It is fed directly no matching device with RG-213 from the remote antenna switch about 50? away at my tower. The coax from the rig to the remote antenna switch is estimated to be ~ 50? in length. A lot of the time running K3EZ to sweep the band (typically 20 watts), it will indicate a 1.0:1 SWR from 7.0 MHz to 7.3 MHz in 20 kHz steps. Occasional deviation from one K3EZ run to another might be due to variations in moisture content of the ground or less than perfect connection to the vertical an uncommon situation. The K3 shows the same readings. Is this 1.0:1 SWR across the entire 40 meter band curious or remarkable? Dick ? KA5KKT ---------------------------------------------------------------------------- ---------- Hi Dick, Some numbers: using the K3 Schematic, "K3S RF Board" Sheet 2, Section B1. The power meter uses a series Schottky diode detector. The low reasonable resolution is about 0.3 VDC, or 0.3 * .707 = 0.21 Vrms out of the directional coupler. The Power for 0.21 Vrms is: 0.21^2 / 50 = .88 mW Assuming a 20 dB coupler 1:10 turns ratio, 0.88mW * 100 = 0.88W reflected power. Assuming forward power of 100 watts and 0.88 watt reflected power the return loss is: 10 * log(100 / 0.88) = 20.6 dB Using the calculator: https://www.allaboutcircuits.com/tools/vswr-return-loss-calculator/ 20.6 dB Return Loss computes to VSWR = 1.222 Therefore, the best lowest estimated K3 VSWR, assuming a 20 dB coupler, is about 1.2. Check my numbers. John KN5L On 7/27/18 9:58 AM, Dick Dickinson wrote: > I've noticed that I'm not showing a reading of less than 1.1:1 SWR on my > antennas per K3 SWR Numerical Readout.

There are many misconceptions and myths about VSWR. To try to overcome some of these misconceptions and to try to provide an easy and understandable summary, Electronics Notes has developed a page describing what VSWR is and this is accompanied by an embedded video. The page and video describe how a perfect match means that all the power is absorbed by the load, and it then goes on to show what happens when there is a mismatch. The case of the open and short circuits are used to show the extreme situations and then these are developed to show what happens with loads that are less than or greater then the characteristic impedance of the feeder. Understanding how the reflected power gives rise to voltage and current standing waves is the key to understanding what happens when there is a high VSWR.

While the SWR of my antenna ranges up to 2:1, the internal ATU kept it below 1.2 across the band. The output remained between 1400 and 1500 W across the band, and didn't drop significantly as the temperature rose. The current was quite high, 54-56 A, and the temperature stabilized at about 70 C during long runs. On other bands, I've noticed a drop in output as the temperature rose, and the ATU doesn't always keep the SWR that low. While I can't rule out something changing in the antennas, it has happened with several antennas, and I've never seen any fluctuation in SWR of any of them. I don't have a dummy load capable of a long term test, but surely Elecraft has run such tests. It would be interesting to see the results of a long term test with, say, a 2:1 load SWR. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From ardrhi at gmail.com Sun Dec 2 12:19:38 2018 From: ardrhi at gmail.com (Gwen Patton) Date: Sun, 2 Dec 2018 12:19:38 -0500 Subject: [Elecraft] Chrome OS and Elecraft Utilities In-Reply-To: References: <50D62AB4-4F52-40A4-91A3-F09CF099B865@law.du.edu> Message-ID: If you use the Crouton tool, you can load a separate FULL version of Linux onto a Chromebook. You will then have the option of using the Chromebook in ChromeOS mode, in which you will "have to deal with "a lot of 'cloud based' stuff" OR you can do the secret Chromebook handshake and use a full version of Linux. The default is Ubuntu. The issues with this are few but are significant: This does not, of course, affect your available RAM or storage space except that you'll have less of each, because you just put Linux on it. The other is that it's an ARM version of Linux, and anything relying on an Intel processor, or a specific chipset will fall over holding its throat making gurgling noises, then expire dramatically. But using Crouton it IS a true version of Linux. You CAN use a "lite" version to save space, but I didn't and it pretty much runs anything you can compile for the ARM processor. A lot of utilities these days that support Linux have builds for the ARM branch, so this is less of a problem than you might think. The Pixelbook ability to run some Linux programs is different, but may have some things in common with it. I don't know, I don't have a Pixelbook, I have a Chromebook I installed Ubuntu on using Crouton. https://arstechnica.com/gadgets/2017/06/how-to-install-linux-on-a-chromebook/ https://gist.github.com/garthvh/07805317032ce7d55887 https://github.com/dnschneid/crouton 73, Gwen NG3P On Sun, Dec 2, 2018 at 12:23 AM Rob Campbell wrote: > It is now possible to run Linux apps on many newer Chromebooks.

I'd guess that it's improbable and likely the result of measurement error. The reflected voltage will be zero for low or high power if the antenna system is a perfect match . However, the (measured) reflected voltage will also be zero for an imperfectly matched antenna system when there is not enough power for the reflected voltage to be above the detection threshold on the measurement device. The Elecraft SWR meters that I have (KPA500 and KAT500) will indicate SWR 1.0:1 with no forward voltage and also with some forward voltage and no reflected voltage. You have to know when to believe the reading and that may be only when the reading is not 1.0:1. Running the sweep with higher power may give quite different results, but running high power antenna sweeps may be considered anti-social. An antenna analyzer will probably give a much better indication of your antenna system characteristics.

Before he would allow me to actually pay for the rig he wanted to be sure all was up to snuff so he sent it to factory to get a top to bottom check out by Keith, WE6R.

Lost a month trying to get it to work while on VK2 holiday for a month. Now been back at it. The rig performs well with the exception of the communication issue. I have tried new interconnecting cables, run the interface to log on every combination of Com Ports, Rates, Parity, Start and Stop, Power, Polling rate and so forth. Because my son, VK2KDP is more computer savvy than I am, and the fact he has his station doing as it should and has helped other VKs get set up, I turned him loose through screen-share. No joy!

Yesterday, I was getting ready to operate SSB and I noted a hum through the monitor when I key the transmitter. By way of background, K3 is 2012 vintage and I assembled the kit. No problems with until this one. I have found several similar threads mentioning a hum on SSB transmit but of the mentioned solutions worked to solve my problem. I have Heil Pro set IC and Heil Gold Elite. The problem seems much more pronounced with Proset IC. Whether it is connected to front panel (FP.H or RP.H Bias on) makes no difference. If I used PTT or VOX it is there. Set Mic Gain at anything above zero it starts. With higher mic gain and higher compression it is worse. I have made some PSK contacts using the LIN IN input and seems to work OK. It seemed like low frequency noise so I set the TX filters for 50 and 100 Hz from 0 to -16. No change. Changed TX Gate from 0 to 10. No change. Disconnected everything from the K3 - RS232 cable, the antennas, keys, and paddle. All except power supply and the Mic. No change. Mic+Lin ON or OFF no change. Curiously, if I put my hand on the rig, it seems to reduce the volume of the hum. Recorded some audio with Proset on my PC and it seems clean - no noise detectable. I wonder if any of you guys - all of you probably more technically savvy than I - can come up with any ideas to solve this problem. Thanks in advance for any help you can give me. 73, Joe AJ1Y From donwilh at embarqmail.com Sun Dec 2 17:06:33 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 2 Dec 2018 17:06:33 -0500 Subject: [Elecraft] K3 stopped communicating with N3FJP log program and Elecraft Utility In-Reply-To: <50937314-8b6f-7b19-6214-93f0936821c4@midtel.net> References: <50937314-8b6f-7b19-6214-93f0936821c4@midtel.net> Message-ID: Tom, Are you operating with a real RS-232 port, or a USB to serial adapter? Don't forget that the serial port or adapter could be part of the problem - also suspect the cable to the K3 RS232 connector. Do you also have the P3 in the RS-232 loop? If so, remove it and connect the PC directly to the K3. What I am asking you to do is strip things down to the most basic configuration and then try again. We very often look to the rig for problems when it could be something external. Can I assume this is a K3 with an RS-232 connection and not a K3S or an upgraded K3 with the USB connection? My comments address the RS-232 connection. Check the RS232 baud rate in the menu and set it at 38400 if it is currently anything else. FACT, some USB to serial adapters do not like to work at slow baud rates, no matter how non-intuitive that might be. Forget N3JFP software or any other software application other than K3 Utility. Start K3 Utility and open the PORTs tab. Put the COM port number you are using into the port box on that page (specifying the COM port is much better than letting it auto-detect which can have false positives. If you are using a USB to serial port adapter and are not certain of the COM port number, go to the PC's Device Manager and open PORTS. If the associated COM port is not obvious, unplug it and see which one goes away - then plug it in again and observe which port is associated with the USB to serial adapter. After telling K3 Utility which COM port to use, click on Test Communications. If it is able to connect with the K3, there is no K3 problem, look at the setup stuff in your software application for the problem solution. If it actually is a COM port failure, it may have to take a trip to Watsonville. Or you may want to upgrade to the KIO3B with the built-in USB to serial adapter and the internal USB soundcard. 73, Don W3FPR On 12/2/2018 4:11 PM, Tom & Barb Valosin wrote: > > I purchased a previously loved K3, S/N 4734 from Rich, W2EG in Sept > 2016.

Very strange. I had just renewed the waterproofing on the splice, so I didn't think that could be the problem. The antenna has been up 8 years, so I spent some hours removing every mechanical connection one at a time, cleaning them (and they were grungy!), and rebuilding the antenna. Surely that would cure the problem? Nope, same results. In desperation I ordered a new Buryflex feedline, as the line sits on the ground in my backyard (never heard of Buryflex before, and the original line is RG213). Was it new when I installed it? I can't remember! By the time the new line arrived, our weather window for working on antennas had pretty well closed, and the contest was getting closer! The antenna was unusable. Lo and behold, we got a day of sunshine, and 40F temps! Out I go, and open the waterproofed connection once again. I'm going to check the antenna tuning at the antenna, and the original line looking back toward the shack, using a 50 ohm termination. Well, the antenna still looks good, so the current choke must also be good. Measuring back through the coax line, I see an SWR of 1:1, which at least indicates to me that the line is usable. Very strange. It looks the same when I move the termination to the antenna end, and measure the line at the shack end. Stranger and stranger ... in desperation, I connect the line back to the splice, and make the same measurement again from the shack, and the antenna seems to be operating first rate. So, I tighten up the connection with a wrench, re-waterproof the splice, pray to the gods, and check it again, and all is as it was 8 years ago. No signs of water in the coax, either. I can only assume that the splice connection to the coax line somehow became loose or disconnected, but it took weeks to do so, after I'd done my adjustments. Didn't feel loose, when I disconnected it. 4 days to the contest, it's all working well - my garden is muddy in the extreme at this time of year, so to Hell with replacing the coax line. The original line seems to be working for the moment, and it will be a lot more fun to do it next spring! Later - 200 QSOs in the contest on the weekend, over 7 hours. I heard EU, very unusual, and worked down into the Caribbean, and out to SD and MT ... and the band was definitely lively. Sure didn't do any harm to clean up that antenna after 8 years, even if it didn't fix the original problem! 73 Mike VE3GFN --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From gliderboy1955 at yahoo.com Sun Dec 2 19:48:10 2018 From: gliderboy1955 at yahoo.com (eric norris) Date: Mon, 3 Dec 2018 00:48:10 +0000 (UTC) Subject: [Elecraft] AXT1--with a twist References: <626583951.591290.1543798090514.ref@mail.yahoo.com> Message-ID: <626583951.591290.1543798090514@mail.yahoo.com> I rigged a camera mout arm to my recumbent trike.?

Most of them have a "tool" (card) to determine screw and thread sizes - use it and buy the appropriate thumbscrew or other fastener. To help you a bit, I would say that the screw thread is either 4-40, 6-32 or 8-32 - those are the commonly used sizes. Yes, there may be an Elecraft thumbscrew. Once you determine the size, look through the KX3 assembly manual to see if there is a match in thread size. 73, Don W3FPR On 12/2/2018 7:48 PM, eric norris via Elecraft wrote: > I rigged a camera mout arm to my recumbent trike.?

" I don't have a K3. I do have loads of recorded data that would allow comparison of KPA500 SWR and LP-100A SWR and a more limited set of data that would allow comparison of KAT500 SWR with LP-100A SWR. I have not performed either comparison but, as a general observation, it's obvious that the LP-100A is far more useful at low power levels or for mismatches that would give low reflected power. At high power levels there is quite good agreement between the LP-100A and the KPA500 for power and SWR. Since I know that, I look mainly at the LP-100A data. I did a quick test on 20 m. For an antenna system load that my LP-100A reports as SWR 1.09 with Z of 52.7 ohm at 4.3 deg it took about 70 W output power for my KAT500 to change from 1.00 to 1.11 SWR. To look at this another way - until the meter moves off the peg it isn't telling you much about the signal being measured. All it's telling you is that you need a better meter. I'm not saying there is anything wrong with the KPA500 or KAT500 SWR metering. You just need to know how it behaves and what it is useful for. I expect the same applies to the K3 SWR meter.

That normally means that the antenna is acting more like a resistance than a radiator. I would expect the SWR on 160 meters to be low only over a 25kHz or at most 50kHz range of the band. When the SWR bandwidth of an antenna increases, you should be looking for a problem in that feedline, antenna to feedline connections or in the case of a vertical, the ground radial system. One possibility is that the radial wires installed were aluminum - they do not last very long in the ground, for some reason, moles like to chew on them. 73, Don W3FPR On 12/3/2018 9:18 AM, Don Roberts via Elecraft wrote: > Lee, it looks like your inverted L wire has stretched.

I doubt it has stretched that far. I see huge swings in my inverted L resonance (with 4 elevated radials) and it is 100% related the ground freezing and unfreezing and ground conductivity changing. My 2:1 SWR points are about 80Khz apart. 2 months ago my resonance was about 1850khz. Today it has slice up and the end result is that my SWR at the bottom of the band is now 2.3:1 when it used to be 1.9:1. That is in 2 readings 28 days apart. My new low edge is 1813Khz. The easy fix is to add 3ft tot he vertical part. In the spring, I will have to remove it again. I have before and after screen shots, but I don't think I can send them to this reflector.

I did not have to do anything special with the radio to make that work. I do have a pretty good RF ground though.? Before I could get any decent performance on 80 (including decent SWR), I added to my RF grounding.? Where the HF coax enters the shack, the shield is pulled to ground (1' of #4 copper to an 8' copper clad ground rod).? That same grounding plate is also connected to another 8' ground rod about 15' away which is right below the service entrance to the house.? A piece of #4 connects from that ground rod to the electric meter base.? All of the #4 is buried except at connections where I've used Pentrox for CU/CU connections.? The ground rod at my HF coax entrance also is tied to 2" wide copper strap that runs into the shack to a copper bar (old -48vdc grounding bar from a phone switch) and all of my equipment is tied to that bar.? Under the shack where the copper strap comes in, the CATV coax and CAT 3 telephone wiring are grounded to that strap.? The CATV coax has a little 4' ground rod right at the wall entrance that is tied to the electric meter base also. This also cured some issues on 80 meters running an RF amp where I could make the phone ring and change channels on the TV when I keyed up!? All of that is fixed.

The AXT1 has two additional unthreaded 1/8" (3 mm) holes which should help with guying, etc. Something I plan to try soon is using the AXT1 as part of an adapter for *stationary* vehicle use of the AX1. (As noted in the manual, you should never use a lightweight telescoping whip on a *moving* vehicle, other than a bicycle.) The idea is to secure a custom-fabricated extender to the AXT1 (at the PEM nut) for use in window, roof rack, or trunk lid mounting of the antenna. 73, Wayne N6KR > On Dec 2, 2018, at 7:28 PM, eric norris via Elecraft wrote: > > One final final: The Elecraft part number for the thumbscrews is E700050 > 73 Eric WD6DBM From k4to.dave at gmail.com Mon Dec 3 14:17:44 2018 From: k4to.dave at gmail.com (Dave Sublette) Date: Mon, 3 Dec 2018 14:17:44 -0500 Subject: [Elecraft] Fred Cady Books Message-ID: Seems I recall a sale of these books announced, but I have lost the email.

I?m using the latest ? ver 1.0.22. I wonder if Roger might consider (in his next update to this program) enhancing the bargraph displays for power, current, and SWR, so that there is a way to see relative readings compared with limits you don?t want to exceed? Perhaps the bar color could change above a certain reading? On the physical amp, you have the yellow and red LEDs for power and SWR which you can see are not lit, and you can see the green LEDs which do light and so you know how close you are to the upper end of the scale. You don?t currently have this ability with the remote program. Also, a peak-hold feature would be nice, so peak power, SWR, and current would hold their peak readings for a few seconds.

Getting an 8A was a prerequisite for getting back to CW mode. I knew I could send reasonable code at 15 wpm with that key but was hopeless with a paddle.

If not, then check the common mode choke on the antenna, you are likely getting RF-In-the-Shack from the antenna - the fact that it diminishes when you put your hand on the K3 amplifies that this may be the problem. Forget about grounding the radio for this problem, solve it at the antenna feedpoint with a good common mode choke on the feedline. Other possibilities are power supply ripple (run it on battery to check) or an open microphone ground lead (try other microphones). Make sure the rear panel jacks are fully plugged (give them an extra push). 73, Don W3FPR On 12/2/2018 4:17 PM, Joe Rogers wrote: > I normally operate CW but the other day and have not been SSB for a few weeks to a month.

Don't flagellate yourself too much.? One of our 6-meter ops blew his K3's finals on Field day a few years ago by inadvertently tapping the ANT button instead of the ATU TUNE button which is directly above it.? Background noise on 50 MHz. being noticeably lower than on HF, he was unaware he was transmitting on Antenna 2 (which had no antenna) and after calling CQ for 15 minutes at 100 watts his finals went to heaven. He now hooks up a dummy load on ANT 2 when using only one antenna. This is an important "gotcha" of which all K3 owners should be cognizant, especially when non-K3 owners are operating the rig. 73, Kent?

If so, the magnetic field of a transformer from another piece of equipment in the shack (such as a linear power supply) may be coupling into your microphone. 73, Dale - WA8SRA On Sun, Dec 2, 2018 at 4:19 PM Joe Rogers > wrote: I normally operate CW but the other day and have not been SSB for a few weeks to a month.

Changed TX Gate from 0 to 10. No change. Disconnected everything from the K3 - RS232 cable, the antennas, keys, and paddle. All except power supply and the Mic. No change. Mic+Lin ON or OFF no change. Curiously, if I put my hand on the rig, it seems to reduce the volume of the hum. Recorded some audio with Proset on my PC and it seems clean - no noise detectable. I wonder if any of you guys - all of you probably more technically savvy than I - can come up with any ideas to solve this problem.

When I last did on air checks, I had the Proset in the rear panel jack and had same hum as in front panel - which, as you pointed out, would indicate that the adapter was not the problem and the issue is in the Proset itself. I am pretty much convinced it is in the Proset IC now. I just cannot understand why after only about a year, I have this failure. My prior Proset was 6 years old and no problem.

Since I am using a KPA 500 and KAT 500, everything goes through Ant 1, and I had had no occasion to use the Ant switch on the K3 itself for quite a while.

Before I could get any decent performance on 80 (including decent SWR), I added to my RF grounding. Where the HF coax enters the shack, the shield is pulled to ground (1' of #4 copper to an 8' copper clad ground rod). That same grounding plate is also connected to another 8' ground rod about 15' away which is right below the service entrance to the house. A piece of #4 connects from that ground rod to the electric meter base. All of the #4 is buried except at connections where I've used Pentrox for CU/CU connections. The ground rod at my HF coax entrance also is tied to 2" wide copper strap that runs into the shack to a copper bar (old -48vdc grounding bar from a phone switch) and all of my equipment is tied to that bar.

I managed to get the antenna -- a slow slung inverted L with a single raised radial as a compromise on my tiny 100 by 100 foot lot -- up in time. I then managed to get the antenna down to an SWR of 2 to 1 measured by a Rig Expert AA55 zoom analyzer, at the balun to which the raised wire and radial are directly attached, and ythen got the same 2.0 SWR reading at the shack end of a borrowed piece of about 50 feet of RG-213. [I recognize that 2 to 1 is not perfect by any means, but it was certainly within the range of my Elecraft equipment, I thought.] >>> >>> But then my K3S simply refused to tune or load into the antenna, either directly, using its internal ATU, or routed through my KPA-500 to a KAT-500 tuner. In both circumstances, the rig and/or tuner showed an SWR around 25 to 1, and tuned at best to around 16 to 1, resulting in no apparent RF output. >>> After trying to fix this in various ways, I gave up on the 160M contest and turned to other pursuits, while seeking advice from several Elecraft-loving, 160M-using, friends. >>> >>> It finally dawned on me this morning to connect the rig to my dummy load. The result of attempting to tune and load the dummy load is exactly the same as it was trying to use the new inverted-L: initial 25 to 1 SWR, tunes down only to 16.9 to 1. >>> The rig, amp, internal and external tuners, and dummy load work fine on 80M through 6M. This is my first time trying them all on 160M. >>> QUESTION: Are there special configuration or other steps I need to take to operate the K3S on 160 meters?

I saw you try to hit the reflector twice but nothing came through. Thanks for that suggestion but I think I found the problem. Looks like 60 Hz leaking into the mic from an open ground somewhere in the mic line to the headset. You raise a good point that I had not considered. I will keep it in mind in case I run into a problem in the future. 73 Joe AJ1Y From: Alan Sent: Tuesday, December 4, 2018 19:18 To: Joe Rogers Subject: Re: [Elecraft] [K3] - Hum on SSB Transmissions Hi Joe, I twice tried to reply on the reflector, but both times the message posted with no text. No idea what's going on. Anyway, you might check if the problem could be hum getting into the mic mechanically. At the community radio station I volunteer for we had hum on the desk mics in the main studio, but only when they were on the same table as the studio computer. I finally figured out it was vibration from the fan in the computer transmitted via the table to the mics. As an experiment you might try lifting the mic off the table. If that makes the hum go away, then it's likely mechanical vibration. The solution could be a shock-mounted mic or perhaps a boom mic mounted to the wall. 73, Alan N1AL On 12/4/18 8:03 AM, Joe Rogers wrote: Hi Don, You hit upon exactly what I did!! When I last did on air checks, I had the Proset in the rear panel jack and had same hum as in front panel - which, as you pointed out, would indicate that the adapter was not the problem and the issue is in the Proset itself. I am pretty much convinced it is in the Proset IC now. I just cannot understand why after only about a year, I have this failure. My prior Proset was 6 years old and no problem. Anyway, I am talking to Heil and hope to get the whole issue sorted out. 73 Joe AJ1Y -----Original Message----- From: Don Wilhelm Sent: Tuesday, December 4, 2018 10:48 To: Joe Rogers ; elecraft at mailman.qth.net Subject: Re: [Elecraft] [K3] - Hum on SSB Transmissions Joe, If you are using the Front Panel adapter for the ProSet-Ic, try plugging the microphone into the MIC jack in the back of the K3 and changing the MIC SEL menu to the rear panel. If the hum is not present, then you have a bad adapter instead of a bad mic. 73, Don W3FPR On 12/4/2018 10:32 AM, Joe Rogers wrote: Hi Don, Thanks for the email suggestions.

If not, then check the common mode choke on the antenna, you are likely getting RF-In-the-Shack from the antenna - the fact that it diminishes when you put your hand on the K3 amplifies that this may be the problem. Forget about grounding the radio for this problem, solve it at the antenna feedpoint with a good common mode choke on the feedline. Other possibilities are power supply ripple (run it on battery to check) or an open microphone ground lead (try other microphones). Make sure the rear panel jacks are fully plugged (give them an extra push). 73, Don W3FPR On 12/2/2018 4:17 PM, Joe Rogers wrote: I normally operate CW but the other day and have not been SSB for a few weeks to a month. Yesterday, I was getting ready to operate SSB and I noted a hum through the monitor when I key the transmitter. By way of background, K3 is 2012 vintage and I assembled the kit. No problems with until this one. I have found several similar threads mentioning a hum on SSB transmit but of the mentioned solutions worked to solve my problem. I have Heil Pro set IC and Heil Gold Elite. The problem seems much more pronounced with Proset IC. Whether it is connected to front panel (FP.H or RP.H Bias on) makes no difference. If I used PTT or VOX it is there. Set Mic Gain at anything above zero it starts. With higher mic gain and higher compression it is worse. I have made some PSK contacts using the LIN IN input and seems to work OK. ______________________________________________________________ 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 n1al at sonic.net From n6kr at elecraft.com Tue Dec 4 22:45:21 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 4 Dec 2018 19:45:21 -0800 Subject: [Elecraft] SSB Features of the KX2 & KX3 You May Have Overlooked... Message-ID: <2C655A63-62DE-44C3-9308-B3C7D0543A5B@elecraft.com> Our KX2 and KX3 transceivers have many standard features targeted specifically at SSB operation. Some are pretty much unheard of in other radios in this class. Just in case you missed them: *** DVR (Digital Voice Recorder) *** You can record and play back two 15 second DVR messages. These are especially useful during contests or SOTA operation, allowing you to store a CQ message, your call, or an exchange. To auto-repeat a played message, just hold the '1' or '2' switch rather than tap it. The auto-repeat interval can be set using the MSG RPT menu entry. *** Speech Compression *** Speech compression can add a lot of "punch" to your low-power signal, bringing up average voice power. As with the K3/K3S, our KX-line compression algorithm is exceptionally clean. Use the CMP switch on the KX3 (TX CMP menu entry on the KX2) to dial in compression of up to 30 dB. *** Receive and Transmit EQ *** 8-band graphic equalizers (MENU:RX EQ and TX EQ) can be used to tailor the receive and transmit audio to your liking. *** Built-In Mic (KX2) *** The KX2 is the world's smallest all-HF-band, all-mode "HT". Using the built-in mic, you can operate the KX2 like any handheld. Tap XMIT to transmit. *** ESSB (Extended SSB) *** If you're on a lightly used band and would like to experiment with higher-quality audio, give ESSB a try. It allows you to transmit with a passband of up to 4 kHz wide (wider than the usual maximum of about 2.8 kHz). Typically ESSB is used at both ends of a QSO, by agreement of both operators. (Again, make sure the additional bandwidth consumed doesn't interfere with adjacent signals -- e.g., don't use it in a contest.) *** Passband Low/High Cut *** When interference is heavy, you can often eliminate it by cutting the low or high end of the audio range. In SSB modes this low-cut/high-cut method is the default. Use the PBT I/II controls on the KX3, or tap FIL on the KX2 and use the two knobs above the switch. *** Auto-Notch *** If a carrier (sometimes called a "tuner-upper") appears, you can use remove it using auto-notch. Hold the NTCH switch on the KX3, or hold APF-AN on the KX2. *** Noise Reduction *** NR on the KX2 and KX3 can be adjusted using a single knob function, from completely a completely "dry" mix (no NR applied) to 100% "wet" (all NR). NR can relieve the fatigue of listening to weak signals on a noisy band. *** RIT (Receive Incremental Tuning) *** Many small transceivers don't provide this important feature. It is often called a "clarifier" because it allows you to tune in signals that are a bit off-frequency. The beauty of RIT is that it only changes your *receive* frequency, leaving your transmit frequency fixed. This is helpful if you're having a conversation with more than one station at a time, where each signal is a little off, such as on a net. *** Stereo Audio and Dual Watch *** The KX2 and KX3 are among very few radios that provide full stereo to the headphone jack. You can use this to advantage during normal operation by setting the AFX MD menu entry to "DELAY" -- this simulates stereo receive audio, giving voice signals a warm, rich sound. In dual watch mode (MENU:DUAL RX), you can listen to your VFO A and B frequencies at the same time, with VFO spacing wide enough to work most SSB DX stations operating split. *** Custom VFO Coarse Tuning Steps *** Using the VFO CRS menu entry, you can select coarse VFO tuning steps independently for each operating mode. In SSB mode, your choices are 0.1, 0.5, 1.0, and 2.5 kHz per step. The default is 0.5 kHz. Bonus feature: If the OFS/VFO B knob is in the OFS setting (OFS LED lit), you can use the VFO B knob to move VFO A in coarse steps while leaving the VFO A knob itself set for fine steps (10 Hz). *** CW-In-SSB Mode *** There are times when you can't quite complete an SSB QSO due to fading, and switching to CW has an advantage. With the CW-In-SSB feature turned on, you don't even have to change modes: just hit the key or keyer paddle and start sending. This feature is particularly useful on 6 meters with fleeting band openings. Many of have successfully completed (or initiated) a cross-mode QSO in this manner. To turn CW-in-SSB on, tap the PRE ('1') switch while in the CW WGHT menu entry. *** MIC Bias and Switch Configuration *** Just about any mic with a 1/8th (3 mm) plug can be used with the KX2 or KX3. To enhance versatility, you can turn mic bias on or off (MENU:MIC BIAS) and specify whether your mic has no switches, PTT only, or PTT and VFO UP/DN switches (like our model MH4). No PTT switch? Use VOX or the XMIT switch. *** VOX (Voice Operated Relay) *** This feature is missing from many small transceivers. It allows 100% hands-free operation for vehicle/bike/pedestrian mobile, or just for operating convenience with a headset/mic. You can turn VOX on/off, set the threshold, and dial in just the right amount of anti-VOX (VOX INH menu entry) to keep the speaker from triggering VOX. *** TX GATE (Transmit Noise Gate) *** This feature is useful if you're operating in a very noisy environment. By adjusting the threshold (TX GATE menu entry), you can automatically cut transmit audio off when you're not speaking; that is, wind noise or other environmental sounds won't be heard at the receiving end. * * * 73, Wayne N6KR From n6kr at elecraft.com Tue Dec 4 23:02:19 2018 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 4 Dec 2018 20:02:19 -0800 Subject: [Elecraft] [KX3] SSB Features of the KX2 & KX3 You May Have Overlooked...

My starting point with TXEQ for maximum talk power is max cut of the three lowest bands (-18dB), 6 dB cut of the fourth band, 3-6 dB of boost on the top two bands. Do that BEFORE setting compression. But EXCESSIVE use of compression can be a very BAD thing. I'd be very cautious about using more than an indicated 1-2 dB on voice peaks.? It should NOT be adjusted to a certain number on? the CMP readout, but rather to the meter that shows gain reduction. Once these settings are done, get signal reports from trained listeners, and tell them to set their RX bandwidth fairly wide. These two settings -- good low cut of voice frequencies and 10 dB of compression can increase talk power by 13 dB. That's multiplying your effective TX power by 20! 73, Jim K9YC On 12/4/2018 7:45 PM, Wayne Burdick wrote: > Speech compression can add a lot of "punch" to your low-power signal, bringing up average voice power.

I stopped after about 30% building while an addition to the house was going on with a move of the ham shack. I kept abreast of the various mods and ordered new firmware twice, ordered toroids from the toroid guy, and finished the build in about 2010. One of the firmware chips never got used. After all the delay and doing the mods without having to undo any thing, it worked fine when I powered it up and aligned it. So I would say about 10 years give or take a month.

Even if I set them really strangely with compression off, it goes back to whatever it was when I turn compression on. So I guess what I?m trying to say is no matter what I do with the equalizer, compression seems to negate it.

My starting point with TXEQ for maximum talk power is max cut of the three lowest bands (-18dB), 6 dB cut of the fourth band, 3-6 dB of boost on the top two bands. Do that BEFORE setting compression. But EXCESSIVE use of compression can be a very BAD thing. I'd be very cautious about using more than an indicated 1-2 dB on voice peaks. It should NOT be adjusted to a certain number on the CMP readout, but rather to the meter that shows gain reduction. Once these settings are done, get signal reports from trained listeners, and tell them to set their RX bandwidth fairly wide. These two settings -- good low cut of voice frequencies and 10 dB of compression can increase talk power by 13 dB.

Haarsager) Date: Wed, 5 Dec 2018 13:52:22 -0500 Subject: [Elecraft] KX3 power on/off Message-ID: I received my AX1 and, anxious to try it out, I dug out my KX3 which hadn't been turned on in at least a year and had worked fine prior to storage. The rechargeable AA cells were dead, of course, so I got the charger, turned the rig on, and went to set the charge cycle. The KX3 wouldn't accept the setting so couldn't charge the AA cells. Then I took the batteries out and used just the AC supply. When I plugged it in, the KX3 turned on instantly, without me doing the normal BAND-/ATU TUNE. Operation seemed normal until I tried to turn it off with the normal procedure. When I did that, the screen stayed lit but blank except for a row of 7 asterisks *******. Next, I bought some new precharged AA rechargables. Same thing. Turns on instantly and can't turn it off. Finally, I performed a reset. This time I could turn the set on *once* with the normal procedure. I knew the reset was going to delete my previous settings, but it also says I don't have an ATU installed when I tried to tune the AX1 (it had tuned fine before the reset). I still couldn't turn the KX3 off, getting the same ******* before I pulled the power. All internal connectors seem to be well seated. Any suggestions would be appreciated (before I make it even worse). 73, Dennis, N7DH -- 598 Haley Rd, Kittery Point, ME 0390 USA From c-hawley at illinois.edu Wed Dec 5 13:55:52 2018 From: c-hawley at illinois.edu (hawley, charles j jr) Date: Wed, 5 Dec 2018 18:55:52 +0000 Subject: [Elecraft] SSB Features of the KX2 & KX3 You May Have Overlooked...

There's a learning curve to operating MS, and QSOs via MS can take a while to complete. It's not unusual for it to take 30 minutes for "rocks" to align in the space between QSO partners to provide the reflections for pings that WSJT-X decodes to complete all the steps of the QSO. MS is NOT a good mode for QRP, and while QSOs can be made with 100W, more power increases the likelihood of a good ping and shortens the time it takes to complete. If you're chasing grids on 6M, MS is a great way to fill in those that are beyond the range of tropospheric propagation and too close for E-skip.? The limit for MS is about 1,300 miles, and even that distance requires great rocks, high power, decent antennas, great ops, and persistence. MS is one of the propagation modes for which the exchange format and progress of WSJT mode QSOs was developed, and it is rigidly followed. 73, Jim K9YC On 12/5/2018 9:00 AM, Mike Cizek W0VTT wrote: > MSK144 on 50.260 WSJT-X v2.0 More info here: > https://physics.princeton.edu/pulsar/k1jt/wsjtx.html > You will find the Ping Jockey chatroom very friendly and helpful: > https://www.pingjockey.net/cgi-bin/pingtalk From wes_n7ws at triconet.org Wed Dec 5 14:44:17 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Wed, 5 Dec 2018 12:44:17 -0700 Subject: [Elecraft] 6m meteor scatter In-Reply-To: <399e6612-c690-1088-68d4-0abcdbc7bd54@audiosystemsgroup.com> References: <9ce71e83-137a-4136-19e1-1c7561047787@metrocast.net> <66a88400-98b1-18be-6786-f541863c0e48@gmail.com> <632869E884D841AFA3F48B1FC949E0D5@X230> <399e6612-c690-1088-68d4-0abcdbc7bd54@audiosystemsgroup.com> Message-ID: <9731ed8f-8104-b4d9-6cbd-f01e76f7920a@triconet.org> Why not just use CW (or even SSB)?

If you have a really good station on both ends, SSB would be a lot faster and more fun in my opinion.? I used to get sked requests from K9NS for contest points on 50 and 144 a few years back. We used SSB and not digi mode. In September it took about 1 minute to complete with him on 144 MHz.? That was with a 20 dB antenna on each end and KWs. You spent more time pushing buttons on FSK-441 . SSB was effortless. I have not tried MSK144 yet.? If you have a marginal setup with less than 1500 w and a big antenna, the digi modes make sense for a faster QSO.? Still, I think SSB is more exciting. CW needs pretty high speed operating ability for manual xmissions, but that is just as exciting if you can swing it.? I can copy at about 35 if I am looking for calls. I think that is a good start for CW! 45 is better. The most fun I ever had in ham radio was working SSB random contacts during a Perseids peak, and then of course the big Leonids shower back in 2001 or 2002. I miss that stuff now.

The feedline buried hardline with an aluminum jacket. The soil here in upstate NY had eaten away the aluminum and produced a goo. When I disconnected all the feedlines to the tower the shield on the 160M feed showed a high resistance. The shield of the other feedlines were providing the return path. So, nice SWR but not a very efficient antenna. 73, N2TK, Tony -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Don Wilhelm Sent: Monday, December 03, 2018 10:07 AM To: don_roberts2000 at yahoo.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] Flumoxed Not necessarily - notice the relatively flat SWR (less than 2:1) over a large frequency range (for 160 meters). That normally means that the antenna is acting more like a resistance than a radiator. I would expect the SWR on 160 meters to be low only over a 25kHz or at most 50kHz range of the band. When the SWR bandwidth of an antenna increases, you should be looking for a problem in that feedline, antenna to feedline connections or in the case of a vertical, the ground radial system. One possibility is that the radial wires installed were aluminum - they do not last very long in the ground, for some reason, moles like to chew on them. 73, Don W3FPR On 12/3/2018 9:18 AM, Don Roberts via Elecraft wrote: > Lee, it looks like your inverted L wire has stretched.

When these radios lose power, they revert to the last saved settings when turned back on. Many settings for these rigs are saved by band, but since Wayne spends some of his available spare time tweaking the firmware to add features like that for more functions and more sets of operating conditions, you need to keep up the the changes when you load firmware updates, and/or study the Menu settings section of the latest version of the manual. 73, Jim K9YC From dave at nk7z.net Wed Dec 5 20:26:04 2018 From: dave at nk7z.net (Dave Cole (NK7Z)) Date: Wed, 5 Dec 2018 17:26:04 -0800 Subject: [Elecraft] OT: T2FD In-Reply-To: References: Message-ID: <4a13e303-de4d-f3a5-afc0-9a6850b34c13@nk7z.net> Your premise would be correct... :) 73s and thanks, Dave (NK7Z/NNR0DC) https://www.nk7z.net ARRL Technical Specialist ARRL Volunteer Examiner ARRL OOC for Oregon On 12/5/18 4:39 PM, Ken G Kopp wrote: > It's my premise that there's nothing actually new in the > antenna world since the '30s ? except the names. > > 73! > > Ken - K0PP > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to dave at nk7z.net > From jasimmons at pinewooddata.com Wed Dec 5 20:41:52 2018 From: jasimmons at pinewooddata.com (John Simmons) Date: Wed, 05 Dec 2018 19:41:52 -0600 Subject: [Elecraft] OT: T2FD In-Reply-To: <4a13e303-de4d-f3a5-afc0-9a6850b34c13@nk7z.net> References: <4a13e303-de4d-f3a5-afc0-9a6850b34c13@nk7z.net> Message-ID: <5C087E60.8080202@pinewooddata.com> Yes and no.....

As pointed out in previous posts, 6am local time is best for meteors, but you tend to get better results an hour or so later because more ops are awake. ?

Hard core DX'ers and contesters will scoff at a BWD-90 or my end-fed 80-10 at 6 ft on the wooden fence, and I don't intend to make the Honor Roll with it, but antennas don't need to be perfect to work and even work well. I snagged VP6D on 40, 30, 20, and 17 CW with 100 W to my WOOF [Wire On Organic Fence] and it was easy. The SOTA folk don't buy a tower, they just hike up a mountain. I worked two DL's in a row on 15 CW a couple years ago from W5N/RO-015 in SE NM with 10 W from my K2 into an Alexloop over my head. If we want younger people to try out HF, we need to assure them that they don't have to spend a year's take-home pay to get on and have fun. Wayne has been relating some of his QRP-ish field adventures which is really great.

Most of the time however, my K3/WOOF serves my needs which leaves the remotes to those on the crew who have no other option.

Lots of great info in this post. I'll expand on this comment. FT8, JT65, and JT9 are noise reduction modes -- the transmit the same message several times in the message cycle, and they use the entire message cycle to do that. They are designed to work on a path that is weak, but exists for most of the message cycle. MSK144, and it's predecessor FSK441, transmit the same message over and over again in segments of a few hundred msec. All it takes is for ONE of those few-hundred msec transmissions to get through. They are designed for a path that may be there for only a few hundred msec or, if we're lucky several chunks of a few hundred msec -- that is, when a meteor has ionized a region of the atmosphere that reflects our signal to the other guy, and, at some later time, the other guys's signal to us. As I understand it, MSK144 does SOME noise reduction, but not much. Another great thing about the implementation of MSK144 is that we can choose TX cycles of 5-30 msec. Last I looked, most stations were using 15 sec. The most surprising MSK144 QSO I've made was with a guy doing a 6M grid expedition through nowhere NV, a path of roughly 400-500 miles, mid-afternoon this past summer. The first stages (three, I think) were done with him driving down the road transmitting 100W into a vertical. He eventually parked and set up a small Yagi for the last two sequences to finish the QSO. I worked him to fill in a total of four or five nowhere grids, and failed on five others. Last I looked, K1JT was suggesting that MSK144 be used where we had previously used ISCAT, another mode designed for tropo scatter. To understand these propagation modes, study the ARRL Handbook and? Antenna Book. It makes very interesting reading, and using those modes can be a lot of fun. Anyone who says that these digital modes and propagation modes are easy has never done it. I've been doing it for about five years, and there IS a learning curve, and the more you know about the digital modes and the propagation modes, the successful you are, and the more fun you have. I've never tried 2M MS -- I'm in a very dense redwood forest (the trees top out around 250 ft and my Yagi is at 125 ft) and those trees are increasingly strong absorbers of RF with increasing frequency. 73, Jim K9YC From tony.kaz at verizon.net Thu Dec 6 07:09:13 2018 From: tony.kaz at verizon.net (N2TK, Tony) Date: Thu, 6 Dec 2018 07:09:13 -0500 Subject: [Elecraft] KPA1500 and Power Line Anomaly In-Reply-To: <1CCF28A1-9B3A-441E-9F79-5594DAF04B7B@coastside.net> References: <5c053da7.1c69fb81.71ea9.bb28@mx.google.com> <044d01d48cdf$2b5e4120$821ac360$@verizon.net> <1CCF28A1-9B3A-441E-9F79-5594DAF04B7B@coastside.net> Message-ID: <062201d48d5c$80d18770$82749650$@verizon.net> Anything is possible.

Yes, I make this point to anyone interested in getting started on HF. I worked my first 50 or so countries with 100 W and a 20 m dipole at 20 ft agl in my attic. If you want an example of working DX with hopeless antennas it would be hard to beat my working VP6D on 160 m and 80 m. I used an OCF wire running round my back yard wall at 5 ft agl. It is matched by a MFJ 993BRT at the feed point and that limits me to 150 W. They must have had zero noise on the island.

There are frequently enough longer pings and burns on 6m that SSB can be used effectively, especially during meteor showers. Many new (and old!) hams aren't even aware of meteor scatter at all and don't realise that it makes working real DX on all of the VHF bands a routine, daily event. Sure, you can't do it with a FM handheld and rubber duck, but with a 100W or more and a reasonable single-yagi antenna, QSO's in the 800-1000 mile range can be made year-round. Perhaps a little off-topic for the Elecraft list-server, but always worth mentioning! 73 Chris (pingjockey.net webmaster) -- 73 Chris Cox, N0UK, G4JEC chrisc at chris.org On Wed, 5 Dec 2018, Jim Brown wrote: > While MS QSOs can be made with random CQing on 50.260, most are > scheduled via Ping Jockey or ON4KST chat.

For those who want to build their own antennas, I suggest starting with a resonant dipole fed in the center. That provides a good match for 50 ohm coax, and a good current mode choke (balun) at the feedpoint keeps RF from flowing back onto the outer shield of the coax which can create a lot of RF in the Shack. Off Center Fed, and End Fed antennas can be made to work with more care. The feedpoint impedance does not match coax, and special care must be used to keep the RF on the radiator rather than coming back into the shack. I realize that OCF and End-Fed non-resonant antennas are popular because they can be used on multiple bands, but there are problems feeding them while keeping the RF on the radiator and not in unintended places such as the shack. For those who want multiband operation, I still suggest a center fed radiator fed with open wire or ladder-line to a good current mode choke balun at transition point to coax is a better choice than OCF or end-fed antennas - keep the coax short and use a tuner that can match the resulting impedance. Make the length of the dipole approximately the length of a half-wave at the lowest operating frequency desired. It will be more "tame" for RF in the Shack than many OCF or End-fed antennas. 73, Don W3FPR On 12/6/2018 8:56 AM, ANDY DURBIN wrote: > "RF current into a conductor will radiate, even if it's at eye level." > From kg9hfrank at gmail.com Thu Dec 6 10:12:28 2018 From: kg9hfrank at gmail.com (Frank Krozel) Date: Thu, 6 Dec 2018 09:12:28 -0600 Subject: [Elecraft] Elecraft XG-1 Manual?

After this message from Wayne I decided to try it again and find it is better than I last remembered. However, on 75/160m where signals are usually quite strong there is a considerable amount of distortion on the received SSB audio when using the autonotch. On these bands I always have the preamp off and attenuator on plus the RF Gain is dialed back to about the two o'clock position on these two bands. If I must get rid of a carrier such as from a group of AM ops 2 kHz away, I'll mostly simply adjust the Hi-cut down to 2.05 kHz which usually cuts off enough of the carrier to where it is not objectionable. Otherwise I must use the manual notch and possibly chase carriers from the round table of boat anchors that don't land on exactly 1945 kHz when I am on 1947 kHz. The distortion effect is along the lines of the autonotch aggressively searching for carriers to notch and it trying to suppress voice peaks. Perhaps the algorithm could be tweaked to lengthen the time the autonotch uses to determine a sine wave carrier as opposed to a voice peak. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

The rechargeable AA cells were dead, of course, so I got the charger, turned the rig on, and went to set the charge cycle. The KX3 wouldn't accept the setting so couldn't charge the AA cells. Then I took the batteries out and used just the AC supply. When I plugged it in, the KX3 turned on instantly, without me doing the normal BAND-/ATU TUNE. Operation seemed normal until I tried to turn it off with the normal procedure. When I did that, the screen stayed lit but blank except for a row of 7 asterisks *******. Next, I bought some new precharged AA rechargables. Same thing. Turns on instantly and can't turn it off. Finally, I performed a reset. This time I could turn the set on *once* with the normal procedure. I knew the reset was going to delete my previous settings, but it also says I don't have an ATU installed when I tried to tune the AX1 (it had tuned fine before the reset). I still couldn't turn the KX3 off, getting the same ******* before I pulled the power. All internal connectors seem to be well seated.

He was obsessing over getting it exactly 43 ft long and getting enough ground radials, when 42 ft would work about as well as 44 ft, and one radial will make a big difference over no radials and two will be better than one, but not twice as better.? I did finally convince him to just put it up, he ran 2 on-ground radials with the intention of adding more, and began using it.? I don't believe he's added any radials yet.

I started out on 40m with a center-fed folded dipole and built many dipole antennas early in my ham radio "career". Currently use a 80/40m inverted-V "fan style" fed with coax and balun. Works most of AK well on those bands. I built a 6m/10m J-pole but never worked well for ground-wave contacts.

This doesn?t affect antenna function, but leaves things feeling a bit loosy-goosy when it?s not snugged up, and can cause some scratching on the inside surface of the clear housing by the bits in there. The housing is held snug by the top assembly which screws onto the threaded attachment rod for the whip. But there are no ?flats? to provide a grip for retightening ? either on the top assembly or the small base ring accessible only with needle-nose pliers on the BNC connector. (The large ring at the base of the housing turns freely, so it does not provide a holding surface for tightening). It?s difficult to get a non-damaging grip on either end to snug things up while keeping the cutout centered over the switch, since my third hand was missing at birth :-) Just food for thought ? The solution is most likely not to over tighten the whip when putting it in place, and making sure you grab the aluminum ring at the top when removing the whip ? not just the plastic tube.

I worked my first 50 or so countries with 100 W and a 20 m dipole at 20 ft agl in my attic. Anyone who has seriously contested and analyzed their results will tell you that 2dB can be the difference between making a QSO over a difficult path or not. Some antennas are more efficient, or have better patterns than others. High antennas radiate better than low ones. Big coax burns less power than small coax. Some antenna tuners burn more power than others. I've worked 175 countries in about five years running 5W into very good antennas. I wouldn't have done nearly as well loading a mediocre antenna. Years ago, AC0C built a complex antenna system in his attic. He's since bought property in the country and built a much better antenna farm. When I got back on the air in 2003, it was with a dipole running through my loft to my garage roof. K6DGW's current HF antenna is a wire running along the top of a 6 ft high wood fence that encloses the small backyard of his condo. Fred drives it with a barefoot K3, and manages to make enough QSOs in contests to have fun. Many years ago, N6BT wrote up his demonstration of working all continents using a light bulb as an antenna.

However, when I look in the manual for a specific function, I will likely see the note with the most current information. RTFM is a popular acronym today. It also implies the "M" (manual) is current. It's our, IMHO, responsibiliy to keep our manuals current. We can even add our own notes, like lessons learned. Once updated, I save mine by adding "Annotated" to the original filename.

Since returning stateside in April, 1965 I have used it, and recommended it, to many a ham as a general purpose antenna.

It didn't seem to matter much if one used 52-Ohm or 73-Ohm coax.? :-) Cheers, Jan K1ND From rmcgraw at blomand.net Thu Dec 6 15:45:57 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Thu, 6 Dec 2018 14:45:57 -0600 Subject: [Elecraft] Less Than Perfect Antennas [was Flumoxed] In-Reply-To: <6f9a770a-7532-963b-3f84-4be9c2c1bd97@audiosystemsgroup.com> References: <6f9a770a-7532-963b-3f84-4be9c2c1bd97@audiosystemsgroup.com> Message-ID: For what appears to be a modest antenna installation, look at the obtained results? of KE4PT.?? Where on QRZ.COM he writes; ""At home, my Icom706mkIIg pushes 100 W through a coax-coil + ferrite current choke to an AH-4 automatic tuner unit at the bottom of a 4.3 m tall, 14.6 m long dual element inverted?L that is strung in the attic of my one-story home [/QST/, Oct. 2007, pp 33-37]. The antenna covers 160 m - 6 m. It's a modest station, but good enough for///WAS-TPA/,/WAC [8-bands]/,/DXCC [225 cfm]/, and/6m-VUCC/, and to copy HAARP lunar echoes on 6.7925 MHz with "/no visible means of antenna/". I'm always looking for Asian stations hidden behind the Auroral "ion curtain".? I enjoy chasing DX. The extra 17 dB that CW has over SSB helps with my modest station, so please look for me at the CW end of the HF bands!"" Yes, what appears as a modest antenna works, and becomes a good bit more than modest when correctly designed, installed and operated as Kai, KE4PT explains.?? Wire antennas do work.? They are the least expensive, easiest to construct, easy to erect and they do work.?? Yet many hams seem to think there is some "magic" to many of the various designs. ? In fact some of the commercial antenna designs are just "lousy" antennas. ? ? One often hears that? "a bla bla is a great antenna".? Well maybe so to them, that is until they encounter a true great performing antenna. And that great antenna is one which usually does not try to defy the laws of physics. Thus a basic 1/2 wave center fed wire, cut to the electrical length for frequency/band of choice, and fed in the center with good quality low loss 50 or 75 ohm coax and erected in the clear as possible and as high as possible is one of the best performing simple and certainly not a mediocre antennas.?? Of course it is a single band antenna.? Buy that fact!? I do suggest a 1:1 current balun at the feed point and unless the coax feed is perpendicular to the antenna, a good common mode choke at the station end of the coax is advised for resolving most Common Mode Current issues. ? Common Mode Currents are not caused by SWR as some seem to believe. As I have the space, my antenna of choice is 250 ft of #10 THHN in the air.? {There is no need to strip off the insulation and a choice of white makes it darn near invisible}.? Otherwise, space lacking, one can use a length that is about 1/2 wavelength at the lowest frequency one desires to operate. 80/75M = 125 ft, 40M = 66 ft, 20M = 33 ft. etc. To make it a multi-band antenna, change the feed line to 450 open wire, or 450 window line, or 300 ohm window transmitting line, and feed it with a 1:1 current balun and a wide range antenna tuner.?? Just keep the coax between the tuner and the balun as short as practical.?? Mine happens to be about 24 inches as I bring the balanced line from the antenna feed point all the way to the balun and tuner at the operating position.?? {A balanced feed system is really easy to use and install and, not as about 99% of the hams will say, it is asking for trouble.? Most that say this have never actually used one but are only repeating what others have said.? I've used balanced feed on at least one or more antennas at every station location of mine for the past 58 years.}? My K3S ATU and/or my KAT500 ATU will put this antenna on any frequency from 1.8 MHz to 52 MHz with less than 1.3:1 SWR. And I do agree with Kai, KE4PT that CW offers about a 12 dB advantage over SSB. 73 Bob, K4TAX From rmcgraw at blomand.net Thu Dec 6 15:47:20 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Thu, 6 Dec 2018 14:47:20 -0600 Subject: [Elecraft] SSB Features of the KX2 & KX3 You May Have Overlooked...

My friend Alan, K0BG, insists this word is actually an acronym which I have used in dozens of presentations: " WithOut Real Knowledge". This means someone made one or more contacts (anecdotes) so this antenna "works." I have used numerous antennas that "work". But, let's say on 40m, the big beam at 145 ft. at VY2TT outperformed anything else I have ever used! We demonstrated the difference between effective and far less effective antennas during FD this year, in spite of S9+ noise on RX. Our A4 (3L on 20m and 15m) and 40m dipole at 40 ft. helped us make more contacts, often four-to-five times as many, thAn other local FD groups, even the ones who ran more rigs than we (single HF rig). Also, my 40m dipole at 40 ft. works much better than many of the other local antennas that "work." Read W8JI's perspective on an OCF dipole and note he recommends an 80/20% split with a CURRENT BALUN. I use an end-fed wire with a 9:1 transformer and counterpoise for SOTA when atop a mountain. When others use a similar antenna at home, they often create RFI in their own shacks, frequently distorting their SSB signals. On the occasion when those antennas "work," they get great reports ("S7--great signal") in spite of 50% distortion. Another op in the same town with a half-wave, center-fed dipole is likely much stronger with no RFI in the audio. The problem--too few ops look into what's going on, give accurate signal reports, or compare their shiny (short and pretty) antennas against a dipole. Yes, I've made HF contacts with a light bulb and yes there is a light bulb contest on the horizon. But, I used my OCF and center-fed fan dipoles at 40 ft. to work VP6D on 160m-10m (excluding 60m), something which I likely would not have done with my 33 ft. end-fed SOTA antenna. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From ve3uvt at gmail.com Thu Dec 6 15:54:49 2018 From: ve3uvt at gmail.com (Chris) Date: Thu, 6 Dec 2018 15:54:49 -0500 Subject: [Elecraft] FS: KX3 Message-ID: I am selling my KX3 due to not enough use.

I had a 2L yagi for a few years as a boy in the 50s, but haven't had anything other than wire fastened to trees since 1960 or so. 100 watts (until recently) and nothing but dipoles and inveretd vees, and almost no time to get on the air, snagged 198 confirmed and very close to 5BDXCC, and one card away from 5BWAS. Hardly major leagues in this crowd, though done with no aluminum whatever. The wire in Colorado is a bit higher than it was on Long Island -- most of it is still not much over 40 feet AGL. But it's at 8,640 ASL. Typical cost of my antennas (excluding feedlines and baluns/chokes, remote antenna switch, lightning protection, and land acquisition) I would estimate at about $25 per band. Efficient? No. Aesthetically unobtrusive and XYL friendly? Yes. Cheap and near zero effort to maintain? You bet. It helps, of course, that what goes to and from the antennas these days connects to all-Elecraft gear.

I am going to access the SDR remotely using SDR Console and run CW SKIMMER on the ARRL DX Contest PC in the home shack. My K3 has no built in Tuner and no 2nd RX. I have been looking at various schemes people are using to split antenna feeds. Some are using a splitter between the RX IN/OUT jacks on the K3. What is the point of doing that? The MAIN Ant port is always used as TX antenna. When RX ANT (Tap) is activated the RX IN Port is connected to the RX/TX and the MAIN ANT Port is connected to the RX OUT port. I see people talking about the RX ANT "LOOP" . As far as I can see there is no RX ANT "LOOP". What is the point of the splitter between those those two jacks.? The jacks are labelled RX IN and RX OUT. The labels imply that the RX antenna also appears at the RX OUT jack but that is not the case. I am just going to connect a BNC "T" in the BOG RG6 line at the radio and feed the K3 RX IN port and the AFEDRI-LAN ANT port. If that doesn't work satisfactorily ...I'll use a passive splitter in the RG6. Am I on the right track? 73 Frank VO1HP Virus-free. www.avast.com <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> From mlmurrah at mac.com Thu Dec 6 18:35:45 2018 From: mlmurrah at mac.com (Lee Murrah) Date: Thu, 6 Dec 2018 17:35:45 -0600 Subject: [Elecraft] Elecraft Name Origin Message-ID: <6DFD278E-E75D-4CFD-9A20-CA79777B48FC@mac.com> I saw Wayne and Eric?s interview on HamNation and enjoyed it very much.

In-Reply-To: Message-ID: I would say that any Pelican box or Otter box which will hold the radio will do a good job. While the internal foam can make a nice custom case, I find my needs change so rapidly that I get at most one trip. Now I just make sure the radio/cameras etc are well padded with enough padding so they won't rattle in the case. The things you can't live without are things like medicines. If you are setting up a well publicized DXpedition, your radios may qualify. If you are just planning a vacation style DXpedition, probably not. The most common problem is luggage lost in the airline system. In this case it will usually pop out in a day or so, although there is a risk of theft by the hired delivery service. Picking it up yourself is safer. To deter light fingers, lock your luggage using locks that take a bit of time to open. I use miniture quick links that have to be unscrewed, taking 5 or 10 seconds. This deters the open and grab artists in the luggage crew who will instead attack someone else's, more conventionally protected luggage where they have a quick way in. In the worst case, only insurance will offer protection. 73 Bill AE6JV On 12/6/18 at 5:07 PM, dean.k2ww at gmail.com (Dean L) wrote: >I have a friend who worked for American Airlines Baggage. >His word to live by: >Never check ANYTHING (checked baggage) you cant live without when you >arrive at your destination! >Light sticky fingers everywhere!!!! ----------------------------------------------------------------------- Bill Frantz | Truth and love must prevail | Periwinkle (408)356-8506 | over lies and hate. | 16345 Englewood Ave www.pwpconsult.com | - Vaclav Havel | Los Gatos, CA 95032 From rlvz at aol.com Fri Dec 7 00:38:07 2018 From: rlvz at aol.com (rlvz at aol.com) Date: Fri, 7 Dec 2018 00:38:07 -0500 Subject: [Elecraft] For Sale: New RRIGSET Remote Control for K3 In-Reply-To: <1678727248a-1ec5-ae6@webjas-vae107.srv.aolmail.net> References: <1678727248a-1ec5-ae6@webjas-vae107.srv.aolmail.net> Message-ID: <167872c5175-1ec4-118c@webjas-vaa226.srv.aolmail.net> Purchased from Elecraft, new in original box: both Control and Remote RRC's for setting up a complete K3 Remote System.?

While being retired in Ecuador I had the advantage to try several antennas. The best over all was a fan dipole for 40, 30, 20,and 17 fed with RG6 up 80 feet AGL mounted on 30 foot bamboo poles at the top of a hill. Next was an 88 foot inverted L fed with 300 ohm line, then two RG6 coaxes, then homemade open line. The horizontal sloped from the 33 foot peak to a 20 foot pvc mast. I noted no real difference with either feed line. I also mounted the 88 footer with 66 feet in a slight vee from 33 feet peak to 20 foot supports for the ends and 11 feet vertical at each end. This also worked well all bands about as well as the inv L. I easily worked Europe Asia, South Africa, eastern and asiatic Russia with QRP or 80 watts. This was a test to see if an 80 meter ant could be installed in a limited space as many homes in Ecuador have lots that are small. While any antenna is better than no antenna, effort should be made to have the best antenna possible. Wire antennas are simple, economical and easy for most hams to iinstall.

Solid state gear is also very unforgiving of mis-matches, unlike an 807 PA with a link coupled tank circuit. [Note how deftly I avoided using the dreaded word, "balun". [:-)] Fan dipoles, where one coax transmission line feeds multiple dipoles on different bands work very well ... if you can get them cut correctly.? There is a lot of interaction between them since all the dipoles are directly fed. The lesser known Coupled Resonator antenna is much more forgiving in the tuning department.? It consists of a center-fed dipole for the lowest frequency normally fed with coax through an unbalanced-to-balanced network.? Close to it [like 1 - 1.5 inches max] are conductors cut for each of the desired higher frequencies, but which are *not* connected to the feed point. Trim the lowest frequency to desired resonance first, then move up to the next in sequence.? There is little if any interaction with the previously trimmed conductors. A convenient construction method is to use open wire or "window line" for the conductors with the lowest frequency one also suspending the assembly.? Trim the other one for the next higher frequency.? For 3 bands, bond another length to the longest conductor and trim the other side for the the 3rd band. I once saw a 5-band C-R with 5 conductors strung through the holes in the crossed spreaders normally used to create "cage" antenna elements.? The fed conductor was larger wire through the center hole and used for suspension, with the other four bands at the ends of the spreaders.? You can also feed the C-R with balanced line terminating at a transformer to get to unbalanced, 50 ohm coax to keep your TX happy. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 12/7/2018 8:39 AM, Don Sanders wrote: > As Don has said, a good dipole as high as possible, even in an attic, fed > with balanced line will out perform most other compromise multiband > antennas. > While being retired in Ecuador I had the advantage to try several antennas. > The best over all was a fan dipole for 40, 30, 20,and 17 fed with RG6 up 80 > feet AGL mounted on 30 foot bamboo poles at the top of a hill.

My solution then was a 40-meter inverted vee with fanned 20 and 10-meter elements, and W9INN coils on the end of the 40M elements to give me 80M.? I was working on 5B DXCC in those days, and eventually concluded the 80-meter side wasn't good enough, so I threw a 280-foot vertical wire loop up in the trees out back, fed through open wire line and a 4:1 balun. Finished the 80M part in just a few months When I moved here I had plenty of space, but not much time, so I threw up a Carolina Windom antenna at only about 35 feet.? Darned thing works so well, despite a site that is in a river valley with higher terrain on all sides, that I'm keeping it. Worked 92 countries during CQWW in about 6 hours on 40 meters, with ~900 watts 73, Pete N4ZR Check out the Reverse Beacon Network at , now spotting RTTY activity worldwide.

As has been noted, an inverted vee is a compromise dipole -- the sort of thing you can rig with a single support. A flat dipole with its center at the same height as the inv vee will have a dB or two more gain, and the directional pattern will be the classic "figure-eight" pattern with broad peaks broadside to the wire and nulls off the ends. Inverted vees tend to lose the nulls off their ends. All this stuff is in the ARRL Handbook and Antenna Book which every ham should own and study as we have time. For rigging heights that are possible for most hams, horizontal antennas for 160 or 80, and 40M over flat terrain produce more gain at greater height. It is a fallacy that an antenna must be low to work short distances. Low antennas radiate LESS signal at high angles than high ones. I published a study of this several years ago. It's here. http://k9yc.com/AntennaPlanning.pdf? beginning on page 10. Field strength at 70 degrees vertical elevation just starts to fall off as it is raised to 1/3 wavelength. That's 45 ft on 40M, 90 ft on 80M, 180 ft on 160M. 73, Jim K9YC From donovanf at starpower.net Fri Dec 7 20:34:15 2018 From: donovanf at starpower.net (donovanf at starpower.net) Date: Fri, 7 Dec 2018 20:34:15 -0500 (EST) Subject: [Elecraft] OT: HF discone In-Reply-To: <774FC6F8-ABCB-4C63-9578-64C6C8F85928@wunderwood.org> Message-ID: <130423371.12040554.1544232855280.JavaMail.root@starpower.net> Its a somewhat improved version of the Happy Accident Ground Plane in January 1957 QST http://p1k.arrl.org/pubs_archive/38955 73 Frank W3LPL ----- Original Message ----- From: "Walter Underwood" To: "Elecraft QTH.net List" Sent: Friday, December 7, 2018 11:45:37 PM Subject: Re: [Elecraft] OT: HF discone The lower element is a cone, but I think the analysis for the discone is pretty different.

Years ago read this would make a good NVIS antenna. Its a fan type dipole with about six inches spread at ends. 40m bandwidth is narrower than a separate dipole. I have the longer legs tuned for 3900 KHz so to work low end I use a tuner. It works well out to 800-1000 miles on 75m and farther on 40m. The Marine HF SSB stations use 4125-KHz in AK as a calling and emergency frequency. A dipole is common for shore stations. Comm Sta Kodiak (USCG) uses this channel thru out AK. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From mike.harris at horizon.co.fk Sat Dec 8 06:41:31 2018 From: mike.harris at horizon.co.fk (Mike Harris) Date: Sat, 8 Dec 2018 08:41:31 -0300 Subject: [Elecraft] K3 Fan Control Command?

Send an email to Howie at hhoyt at metbel.net and ask for the best method. You could also try info at proaudioeng.com. I strongly recommend you do it today ASAP. Howie is in the same area I am, and we are expecting extreme winter weather late tonight and through Sunday (maybe Monday) which can bring ice and snow and can create disaster to power lines, so we may be without power for a period of time. 73, Don W3FPR On 12/8/2018 8:01 AM, Richard watson wrote: > Good morning listers, > I am a new (back after 20 years) ham and just received my power supply > from pro audio.

I bring my balanced line all the way to the operating position where the balun is located and only about 18" from the tuner. There is no issue running the insulated balanced 300 ohm line through windows, walls, ceilings, floors and such.??? Just maintain about 10" or so from any metal gutters, metal duct work, AC wiring, phone lines, water lines and such. The question often arises about RF in the shack when using balanced line.?? If the line is reasonably well balanced the current in each side of the line is equal but 180? difference in phase.? The result is the field cancels and there is no radiation into the shack.??? Thus using a balanced feed system on a center fed antenna is the optimum configuration. 73 Bob, K4TAX On 12/8/2018 9:03 PM, Robert G Strickland wrote: > Ron... > > Would such an antenna cut for 80m, fed with ladder-line, and used on > 40m, be a better performer on either band than an 80-40m fan dipole > fed with 72ohm coax?

If it is more gain broadside (perpendicular to the antenna) then the answer is yes. On 80 meters the 160 meter elements alone will be Two Halfwaves in Phase and will have 2 to 3 dB of gain broadside to the antenna. Of course, that gain comes at a cost of radiation in other directions. L.B. Cebik (SK) explained it best - if you visualize the radiation from an isotropic antenna as a balloon, then squeeze that balloon so the largest projection is in the direction(s) of the gain, you will see the reduction of gain in other directions. In other words, there is no free lunch. For the dipole, squeeze the balloon in the middle a bit, and for 2 half-waves in phase, squeeze it a bit harder. If you want to achieve the maximum squeeze, change the length of each half of the radiator to 5/8 wavelengths and you will have the greatest broadside gain before the radiation pattern breaks into multiple lobes. You can find that basic information in most any good antenna handbook. It is the basis for all wire gain antennas. For rotatable arrays or other directional switchable arrays, that balloon effect is exactly what is desired, but for a fixed wire antenna, that balloon effect may not be desirable if you want to work stations that are off the ends of the antenna. So the answer is -- it all depends. Do you want to orient your antenna to favor certain locations, or do you want something more or less omnidirectional. An Inverted Vee will be slightly more omnidirectional than a horizontal dipole. A vertical is an omnidirectional antenna with a circular pattern, but normally with a lower take-off angle than a dipole at a modest height. If you want to work nearby stations as well as those further away, use a dipole - if you want to work DX (which usually comes in at low elevation angles, use a vertical. 73, Don W3FPR On 12/8/2018 10:03 PM, Robert G Strickland wrote: > Ron... > > Would such an antenna cut for 80m, fed with ladder-line, and used on > 40m, be a better performer on either band than an 80-40m fan dipole fed > with 72ohm coax?

First, resonant dipoles are a much closer match to 50 or 75 ohm coax than to 300 ohm line. Low dipoles are closer to 50 ohms, higher ones closer to 75 ohms. Second, the MOST important place for a choke is at the feedpoint. The feedline is part of the antenna until it hits the first choke! If, for example, the feedline is 60 ft long and the only choke is at the shack, that 60 ft of feedline is picking up noise and can be de-tuning your antenna. Additional chokes along the line can prevent the feedline from interacting with nearby vertical antennas, and can further reduce feedline noise. Third, N6BV wrote an excellent piece for QST several years ago observing that it's VERY easy to fry a common mode choke on a line with high SWR.?? This happens when the choke is at a high current point on the transmission line, overheating the line and the ferrite core. I will soon publish a new Choke Cookbook for chokes wound on a single #31 2.4-in o.d. core with RG400, a #12 teflon pair, and a #12 THHN pair. I am no longer recommending chokes wound with RG8/11/213 size coax, for reasons that will be detailed in the applications note that comes with the "cookbook." I've been beta testing THHN and enameled pair chokes for years; recent work shows that that RG400 and teflon #12 are the better choice. An 80/40 fan dipole will perform as well as separate 80 and 40 dipoles at the same height -- the only compromise is that SWR bandwidth is reduced by about half on 40M, but a fan dipole cut for the center of the band is still below 2:1 at the band edges. As to sag -- height IS a good thing. Modeling shows that horizontal antennas, it takes a change of 5 ft on 40M for between 30 and 70 ft, and 10 ft on 80M for antennas twice that height to make a difference of 0.9 dB.? That work is presented in this peer-reviewed paper. http://k9yc.com/AntennaPlanning.pdf? The discussion of rigging height begins around page 10. Yesterday in this thread someone questioned my statement that the difference in field strength between a horizontal dipole and an inverted Vee with it's apex at the same mounting height was in the range of 1-2 dB. For another project, I just modeled an inverted Vee for 80M with it's apex at 46 ft and ends at 17 ft. The difference was about 1.5 dB as compared to a horizontal antenna at 46 ft. Bringing the ends further down will, of course, increase that difference. I didn't model it, but 3dB seems a reasonable number. But remember, with antennas, higher is usually better. :) When we use Inv Vees for portable setups, we always try to rig the ropes for the ends of the antenna as far away and as high as possible. 73, Jim K9YC On 12/8/2018 8:00 PM, Bob McGraw K4TAX wrote: > The 80 / 40 M fan dipole fed with 300 ohm transmitting line {The > Wireman #562} and then use the balun at the point where the feed line > enters the house would be preferable.

L.B. Cebik (SK) explained it best - if you visualize the radiation from an isotropic antenna as a balloon, then squeeze that balloon so the largest projection is in the direction(s) of the gain, you will see the reduction of gain in other directions. In other words, there is no free lunch. For the dipole, squeeze the balloon in the middle a bit, and for 2 half-waves in phase, squeeze it a bit harder. > If you want to achieve the maximum squeeze, change the length of each half of the radiator to 5/8 wavelengths and you will have the greatest broadside gain before the radiation pattern breaks into multiple lobes. > > You can find that basic information in most any good antenna handbook.

Do you want to orient your antenna to favor certain locations, or do you want something more or less omnidirectional. An Inverted Vee will be slightly more omnidirectional than a horizontal dipole. A vertical is an omnidirectional antenna with a circular pattern, but normally with a lower take-off angle than a dipole at a modest height. > > If you want to work nearby stations as well as those further away, use a dipole - if you want to work DX (which usually comes in at low elevation angles, use a vertical. > > 73, > Don W3FPR > >> On 12/8/2018 10:03 PM, Robert G Strickland wrote: >> Ron... >> Would such an antenna cut for 80m, fed with ladder-line, and used on 40m, be a better performer on either band than an 80-40m fan dipole fed with 72ohm coax? Leaving all other extraneous but influencing parameters aside. I have the second antenna; the weight of all that wire and the coax with a ferrite balun results in a significant sag. I'm wondering if the first antenna, lighter and higher in the air, would perform better?

They are not easy to measure.? You can't measure them accurately with a single-port antenna analyzer. N6KT, a member of our contest club is building a station in the Caribbean and asked me to measure a Balun Designs 1115T common mode choke (often called a 1:1 current balun). It looks NOTHING like it's data sheet, which shows an approximately flat high choking impedance over the HF bands. It would be USELESS on 40, 80, and 160M! From what I've seen them write about chokes, I don't believe that they understand how common mode chokes work, and I certainly wouldn't suggest that someone ask them for advice. The Wireman 8232 is based on W2DU's excellent work from many years ago. He built chokes with 50, 100, and 200 of the largest #73 Fair-Rite beads that fit over RG142. This size bead of this material has the unique property of relatively constant choking impedance in the HF spectrum, but you have to a LOT of them.? Only the 200-bead choke has sufficient choking impedance to handle high power and kill receive noise, and that's what he recommended, yet most products sold as a "W2DU balun" have many fewer. The larger #31 cores are not useful at HF until you wind multiple turns through them, but are often sold for use as a string of beads on coax. How many beads are in the 8232? Are they Fair-Rite #73? 73, Jim K9YC On 12/9/2018 5:33 AM, Bob McGraw K4TAX wrote: > Balun Designs, both 1:1 and 4:1 for use with tuners.

A Buddipole in a horizontal configuration is off-center fed because it is inherently physically short and low, and the center impedance is also low ... ~20-30 ohms on 20 meters.? Moving the feed point out toward one end raises the impedance seen by the 50 ohm transmission line.? It also unbalances the entire system leading to undesirable current on the outer surface of the coax shield conductor. And, to the original subject I assigned to this thread, how many remember the Windom feed that Novices, who couldn't afford transmission line, used in the 50's.? Definitely "Less Than Perfect" but there are QSO's in my log using it. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 12/8/2018 7:03 PM, Robert G Strickland wrote: > Ron... > > Would such an antenna cut for 80m, fed with ladder-line, and used on > 40m, be a better performer on either band than an 80-40m fan dipole > fed with 72ohm coax?

Yes. Others have correctly identified the reason, but I'll go into a bit of detail for clarity. Noise cancellation works by amplifying a tiny mic on the outside of an earphone and feeding it to the headphones so that the acoustic output is out of polarity with the noise that is acoustically coupled to the ear. For deep cancellation, the sound from the mic and the sound that reaches the ear directly must be of precisely the same amplitude AND precisely the same phase (but out of polarity). This is particularly difficult to achieve, because 1) the headphones themselves attenuate the direct coupling of the noise to the ear, and that attenuation is not flat, and it varies depending on subtle differences in how the earphones fit/seal to the listener's head; 2) Phase is a variable, not a constant, and increases in direct proportion both to frequency and the distance that sound travels. 3) The small distance between the noise-sensing mic and the ear results in phase shift that increases with frequency. 4) The earphones themselves have non-flat phase response. 5) Directivity of both the microphone and the ear covered by the headphone is another variable. The above leads to these conclusions. 1) Low frequency noise is far easier to cancel than higher frequency noise. Noise produced by fans in the KPA1500 has significant higher frequency spectra. 2) Extreme care is needed in the design of noise cancelling headphones. I would expect products of serious audio companies like Sennheiser and Bose to be better performers. 3) I would expect to see new designs using DSP to introduce delay to reduce the time difference resulting from mic placement and equalization for non-flat amplitude and phase response of the total system. K9MA says that Radio Sport headphones effectively kill the sound. I have no problem believing that -- they're designed for use in high noise environments. But don't buy a pair until you've tried them on -- headphone comfort is a VERY individual thing that depends on the shape of our heads. Some contesting friends like them, so I've tried them on at several hamfests, and found them an instrument of torture. I couldn't imagine wearing them for even a few hours. 73, Jim K9YC From ghyoungman at gmail.com Sun Dec 9 14:34:54 2018 From: ghyoungman at gmail.com (Grant Youngman) Date: Sun, 9 Dec 2018 14:34:54 -0500 Subject: [Elecraft] Noise-cancelling headphones mystery In-Reply-To: References: <1062450814.1134995.1544361407222.ref@mail.yahoo.com> <1062450814.1134995.1544361407222@mail.yahoo.com> <22065279.297181.1544373621164@mail2.virginmedia.com> Message-ID: <127C17E1-0AEF-4CEE-B25F-35C80B758069@gmail.com> I find the RS60 very comfortable for long periods.

Define "they work." :) They don't blow up? You get signal through them to the antenna? They reduce common mode current? They reduce RX noise? You make QSOs with them in line? They make you feel good? The REASON for using a common mode choke is to reduce common mode current. That can reduce noise a bit -- the part of it picked up on the feedline, and it can eliminate the part of TX RF coming into the shack on the feedline as common mode current. By my definition, if a choke does that, or can do that if there's noise, it works. If it doesn't do that, or can't d that, it's not working or it's not a good choke. Chokes installed on antennas rarely make a large difference in noise -- a few dB is typical if your antenna is close to the noise source, it also picks up the noise. But if the antenna is far from the noise source and the feedline runs close to the source, the reduction can be more than a few dB. AND, when that DX you're trying to work is weak, that few dB can be the difference between copying him or not! 73, Jim K9YC From k4to.dave at gmail.com Sun Dec 9 21:52:19 2018 From: k4to.dave at gmail.com (Dave Sublette) Date: Sun, 9 Dec 2018 21:52:19 -0500 Subject: [Elecraft] KX3 has died In-Reply-To: <92D4977F-8630-4EBB-9150-637EAC21D4DD@wunderwood.org> References: <000001d4901a$e2aa0650$a7fe12f0$@elecraft.com> <92D4977F-8630-4EBB-9150-637EAC21D4DD@wunderwood.org> Message-ID: It is not looking good, folks.

I'm updating using a MAC. I don't think that has anything to do with the problem. It has worked perfectly for four years. Doesn't say that something couldn't have died. But the MCU LD and flashing Tx LED on the KX3 says there is a firmware error and I don't think a failed interface cable or computer would cause that. I'm not a computer guru. It will be interesting to see how this plays out. Thanks to all for helping. This is a knowledgeable and friendly group to deal with.

This all culminated in products that Spiderbeam now sell world wide, likely the only ocfd that work properly. He also has a section on his website called the Battle of the Baluns which is worth a read. He's not into physics just sound, repeatable, practical measurements.

The RX IN/OUT jacks are for the insertion of an external preamplifier or a splitter to tap off the main TX antenna. If using only RX IN, that antenna input will be used when you select RX ANT. Since you are using a separate RX antenna and want to split it to the K3 as well as another receiver, put the "T" or splitter on the antenna, one output to the K3 RX IN and the 2nd to the other receiver. On the K3, you will have to activate the RX ANT - if you do not, the receive will be from the main TX antenna. 73, Don W3FPR On 12/6/2018 6:15 PM, Frank VO1HP wrote: > I am want to split my BOG RX antenna between my K3 RX IN jack and the ANT > port on my AFEDRI-LAN SDR at my remote site.

Try this a few times, it sometimes needs that to pass.? Once it passes, save that config, then make sure it passes again.? And again until you're satisfied. Then check the power out at 100W. Failing that, time to call support.

I vote yes and did so myself. The amp just loafs along and probably prefers that voltage. However, properly configured at the transformer, it runs fine on 120v which is what I power it when portable for Boy Scout events. At some point you may want a 1500w amp which will definitely need 240v. Might as well do it at today?s electrician rates than tomorrow?s. 73, Kent K9ZTV > On Dec 12, 2018, at 6:13 PM, Tom Berry wrote: > > Is there any advantage to use 220 V over 110 V on the KPA500? > > Is it worth having an electrician come to the house and install a 220 V outlet for it? > > > Thanks > > Tom AA4VV > > ______________________________________________________________ > 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 k9ztv at socket.net > From w6jhb at me.com Wed Dec 12 19:27:47 2018 From: w6jhb at me.com (James Bennett) Date: Wed, 12 Dec 2018 16:27:47 -0800 Subject: [Elecraft] KPA500 AC power In-Reply-To: References: <7b35ac8a-7649-3567-82b3-b15a9b8179c5@comcast.net> <68b547dd-7cfa-61f3-f23f-f2d5d6273e0e@triconet.org> Message-ID: I?ve wondered the same thing here.

The current draw when running at 220V will be half that needed for 110V, which means the heat losses in the power cord and wall wiring will be cut by about one-fourth. This also means the voltage drop on the power cord and wall wiring will be much less at 220V. So, there is a pretty good advantage to running the amplifier at 220V. Having said that, I wasn?t willing to go through the trouble to add 220V outlets to my workshop, so my KPA500s run on 110V. You will hear many folks saying they run the KPA500 just fine at that voltage. Generally if the lights blink when you key the radio it is a good indicator that the wall wiring is too small. In that case you may want to have the electrician install the higher-voltage line. From experience I know that changing out wall wiring is a major effort involving wall patching. Basically, if you want to go through the trouble, go for it. Otherwise enjoy your KPA500 at 110V. 73 and enjoy the KPA500!

If you have to run new wiring to the shack, run 240 volts and if you run a 4 wire system, it can be split out to 2 120 volt receptacles that you can use exclusively in the hamshack. Your electrician will know how to split it out. Ask him to use #12 wire, or better yet #10 for a lower voltage drop from the breaker box. Many receptacles are wired with #14 wire (except for kitchen circuits which must be #12 wire according to code). If you have an older house, definitely get dedicated wiring to the shack - who knows what older wiring may entail, it was wired only to the codes at the time of construction. 73, Don W3FPR On 12/12/2018 7:13 PM, Tom Berry wrote: > Is there any advantage to use 220 V over 110 V on the KPA500? > > Is it worth having an electrician come to the house and install a 220 V > outlet for it?

If you have a stiff 120 V service from the breaker panel, a service that doesn't loop through other outlets, specially the ones that use the push in the wire type connections, then the KPA500 will run OK on 120 volts.?? If you have other stuff on that circuit,? or have the maximum legal number of duplex outlets of 5 on that circuit, then you may be approaching the limit of a 20 Amp circuit. The IR drop between 120 volts and 240 volts is noticeable, more so as the distance from the breaker panel to the load increases. The IR drop in the wire from the breaker panel to the outlet will be reduced by 1/4th when operated on 240 as compared to 120. There is drop in the outlet, the power cord and such, all will likewise be reduced when a 240 volt service is used.?? And then if you ever go to the KPA-1500, there is no choice except 240 volts. I ran a dedicated 240 volt service, 20A from the breaker panel with #10-4 wire and feed it from 2 single breakers.? The larger than required wire size makes for less IR drop.? I also have? 2 duplex 20A 120V outlets which are fed from each leg of the 240 V service thus the reason for using #10-4.? That provides L1, L2, Neutral, and Ground as required for the 120V duplex outlets.? This way I have a good solid power feed to the station.

Message-ID: Please forgive me if this is a FAQ. If it is, just point me to where I can find the old answer and I won't bring it up again. I can usually get the CW decode to work if I can clearly hear the signal. The CWT bar flashes and the text scrolls, and it gets a lot of characters right. BUT... ...that's only if I have the preamp OFF. I've tried using the preamp but decreasing the RF gain. I've tried using the preamp and the attenuator. I even tried setting a couple of bands to only 10db preamplification. But if the preamp is on AT ALL, the decode either never gets a "lock" and the CWT bar is flickering randomly (no matter what the threshold setting is) with no decode, or the CWT bar is solid, no flashing, and there's no decode. If have the preamp OFF, the same signal will usually decode at least somewhat, and sometimes excellently. Most of the time, W1AW can decode fairly easily...though FLDIGI and CWGET seem to decode more reliably. They'll decode 80-90%, while mush is appearing on the PX3 display lines. But at least I get something with the preamp off. But there's just some times when the signal is weaker and I can't get the threshold to crack without the preamp. But then I get no decode at all. Am I doing something WRONG? Is there some step that I'm not understanding? Heck, I've seen past entries in the list where some have said they can't get decode unless the preamp is ON! Or is there some known issue with preamp + decode that I haven't seen? Mind you, my antenna, while not fantastic, is adequate for me to get to Europe on FT8 at 35 watts. I even got from Philly to Fargo on 50w FT8 on 30 meters, using an indoor magnetic loop I built. So it's not my antennas. I have signal, but paradoxically, when the signal is strengthened by the preamp, I get lower decode performance. I'd expect that in high-noise conditions -- amplifying the noise as well as the signal and hashing them both -- but when the noise floor is low and the signal is just made more solid with the preamp, I should be able to decode it with the same technique as when I use it on a stronger signal without the preamp. Shouldn't I? Or am I simply not grasping some fundamental issue? I've read the manual, I've read mailing list archive messages, I've experimented with my own second rig on a dummy load sending a canned CW message (K2 s/n 1641). This will, I hope, be a moot point in a few months. I'm trying to learn to copy the CW barebrained instead of using the decoder. (I got rusty from when I first learned it back in 1999.) But I want to at least be able to check my copy using the decode function if I can until then. Between them, maybe I can hold a coherent QSO!

In-Reply-To: References: Message-ID: <7601108f-5101-d5ad-2021-3b33ee110d74@blomand.net> I'd say initially that you aren't configuring the radio for the best decode.?? Here's something I wrote some months earlier.?? It might prove worthwhile in your case.? Of course not knowing what bands and your noise conditions is something you'll have to judge for yourself.? You may need to change the TEXT DEC value to a lower or higher value. **************** As to RF gain, I find many hams do not understand the way to get enhanced performance from their radios.?? And this applies to most all legacy radios today.?? More RF Gain does not assure one they can or will hear weaker signals.?? The story is Signal to Noise ratio, namely in the area of the receiver noise floor.??? Since we can't change the RX noise floor, as it is established by design, then we need to change the signal coming into the radio. Typically one wants the no signal band noise to be some 10 dB above the noise floor of the receiver.? And to do this we use a combination of attenuation and RF gain reduction. To run the math, if the RX noise floor is -135 dBm, typical of most modern radios, then the "sweet spot" for no signal band noise is -125 dBm or about S-1.? The -125 dBm value is 10 dB above the receiver noise floor. ?? If the no signal band noise is -97 dBm {S-5} then we need a combination of 28 dB attenuation and RF gain reduction.? I typically use 15 dB attenuation and then back the RF gain down a good bit on 75M.? While on 10M and 6M I will switch the attenuation off and engage the preamp.??? Running high gain and no attenuation just to see the S meter move upscale is just sucking up receiver headroom and certainly doesn't do anything constructive toward improving signal to noise ratio. Cranking up the RF gain and adding the preamp in many cases is the wrong way to go.? I hear all the time about stations running the receiver preamp on 80/75 meters.?? WOW, they must have a really really low no signal band noise.? Something like -135 dBm. In your dreams. ******************** Hope this helps. 73 Bob, K4TAX On 12/12/2018 7:21 PM, Gwen Patton wrote: > Please forgive me if this is a FAQ.

My K3s is finally enroute back home after a 6 week stay in the Elecraft Repair Department with a blown FET in the HPA, cause unknown. And I know I've been told I'm not the only one to suffer this failure, and it sounds like this is now a known issue. Does anybody have an idea as to what could be causing these FETs to fail, or steps to consider to lessen the chances of it happening? I can't speak for anybody else, but I baby the heck out of my gear and was shocked to discover it failed, when feeding directly into a KPA-1500. ---------------------------------------------------- Regards, Peter Dougherty, W2IRT -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wes Stewart Sent: Wednesday, December 12, 2018 4:55 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 Suddenly Putting Out Only 25 watts at 100 watts indicated If you have another receiver, run a two-test and listen to the K3 output in a narrow BW.

That can depend on how long the run is from the power panel to the outlet. For CQP and 7QP expeditions, we run KPA500s on 120V, and have had issues with under-voltage faults caused by too much IR drop combined with regulation issues with the generator. At home, I run my KPA500 on 240V, because I had 240 brought to the shack before I moved in. Since the power supply is unregulated, an advantage of running on 240V is slightly less voltage drop when the radio is keyed. BTW, IR drop and the associated power lost in wiring feeding electronic loads is significantly greater than predicted by Ohm's law for a sine wave because the current drawn by power supplies is not a sine wave -- current is drawn at the peaks of each half of the AC cycle to recharge the input filter capacitor. 73, Jim K9YC From idarack at gmail.com Thu Dec 13 08:07:55 2018 From: idarack at gmail.com (Irwin Darack) Date: Thu, 13 Dec 2018 08:07:55 -0500 Subject: [Elecraft] KPA500 AC power In-Reply-To: References: <7b35ac8a-7649-3567-82b3-b15a9b8179c5@comcast.net> <68b547dd-7cfa-61f3-f23f-f2d5d6273e0e@triconet.org> Message-ID: Unless you are having a problem, save your money.

If so, after "training" the tuner across the band of interest with any one antenna, change it to MAN mode and it will not try to re-tune. As you said, the KAT500 follows the K3 VFO, so there should not be a need for any retuning. The problem is that the forward and reflected powers cannot be read simultaneously. So if the forward power is read when the power is low, and the reflected power is read when the power is higher, an erroneous SWR calculation will result. 73, Don W3FPR On 12/13/2018 9:19 AM, eric norris via Elecraft wrote: > I am using an early KAT500 with a K3S.?

Message-ID: A very unpleasant dinner last night at a restaurant with a reported noise level of 84 db ? about the same as a gas engine lawn mower seated at the next table ? raised what is probably an elementary question. 3 db is the familiar doubling of power, and in an audio environment is a doubling of acoustic energy, I understand. However, I have read that ten db is what results in an apparent doubling of the sound level as we hear it. Is the difference attributable to something like an AGC circuit in the human auditory system? And as for RF transmitter power, does it take a ten db increase rather than 3 to effect an apparent doubling of audio amplitude in the ears on the other end of the QSO? Never mind the S meter ? I mean the actual ability to hear a signal over the noise, or over the QRM. Help, anyone?

That converts to 12.5A at 240v if PS is 100% efficient. At 120v that would run 25A which exceeds rating or No. 12 house wiring. I now have a 1200w sspa that draws 50v-50A (2500w dc). I installed my own 240v using 8-4 wiring bought at Home Depot. I get about 2vac drop when keydown at 1500w RF. I installed a small breaker box in the shack with one dual 20A breaker for 240v and split out two 120v 20A ckts which run my 12v-50A station PS and a 26v MOT repeater PS for my 220-MHz 150w PA. I also have a 1000w 50-MHz sspa powered by 50v-50A switching PS (2500w dc) that uses 240vac. Only run one QRO amp at a time. Running the 8-4 wire from my main load center down thru crawl space under the main floor then back up thru spare bedroom (shack) floor; about 35-foot run. I drilled small holes in floor joists to tie off the cable using wire ties. Crawl space is 4-foot high. Obviously if your house is on concrete slab you would need and alternative. Suggest running outside on house wall with conduit (which can be pvc if cable is sheathed). We have very lax building codes up here so home self-construction is common.

The KPA500 is listening to the same Band signals as the KAT (but not the Auxbus data), so I would turn on the KPA500, leave it in standby, and watch the display and listen to its relays to see if it changes bands when the K3 does. I think the key here is to determine exactly what the WSPR code is sending the K3. Is it also sending data to the KAT500? If so that stream would also be telling. If the computer is commanding the K3 to go into transmit before all the commands have been received it could cause a situation just like you describe. It might be up to the software author to fix this situation. 73! Jack, W6FB > On Dec 13, 2018, at 6:19 AM, eric norris via Elecraft wrote: > > I am using an early KAT500 with a K3S. When using WSPR in band-hopping mode at 5w, WSJT-X 2.0 commands a band change and transmit, the K3S starts transmitting, then stops, changes bands, then changes back to the original band, say 40 meters. I think this part is a WSJT problem, and has been reported. Now the K3 is on 40m. If I press the TUNE button in WSPR, the SWR meter shows a high SWR and relays click in the KAT500. If I press TUNE again, the swr is good. > The KAT500 is configured to follow the K3 vfo, so why is the KAT500 retuning? If the K3 shows 40m, why wouldn't the KAT500 have the proper tuning solution? It is properly cabled with auxbus cables between the K3, KAT500, and KPA500 in that order (the KPA500 is off). The KAT3 is in bypass mode. I don't think this is an rf problem because I regularly use the KPA500 with no signs of rf getting into anything. This seems very odd. All firmware is current.

This is true for music as well as speech or CW.

I copy code in my head but have played with the CW decoder on my KX2 for amusement and also at our FD station so the others could see what was being sent and received. A couple were interested in learning the code. One fella brought an MFJ CW reader. We could not get a "solid copy" on either of them except on very strong signals. With typical band conditions and even sorta weak QRP stations, I can get maybe 80% copy - not bad, but not 100% copy. I've also found the threshold around 3-5 to be the best, like you, though does tend to change from station to station and day-to-day depending upon band conditions. > So there's more at work here than signal strength. The advice on better copy without excessive RF gain is valid. However, you do need that extra gain to properly drive the CWT and decoder on most signals, as you noted, even if the signal-to-noise ratio is compromised. Tuning and filtering is also important. I usually set my CW filter at 25-30Hz for best decode and push the button that sets the VFO to the proper offset to center the CWT ... then tweak the VFO just a bit for best decode. Lastly, I have found the decode to work better at 18-20 wpm or higher; slower code speeds is prone to triggering on noise. I would recommend tuning where there are no signals - just noise - and set things for no false decode from the noise, then tune to the station you want to decode. Hope the above helps. The decoder can be a good tool for helping you learn the code, just realizing you will seldom achieve 100% copy on the decoder (and sometimes even by ear!). I admire you for your desire to learn the code. It takes a lot of nerve to get on the air for those first few QSOs. We all remember our first QSOs. And as we'll all tell you, the best way to improve your CW is to get on the air. Most CW ops are more than willing to match your code speed (except in a contest maybe) to give you an enjoyable QSO and help you along. Sorry for the long reply, but hopefully helpful to you and some others. 72, Paul NA5N PS - email me if you'd like to arrange a sked on the air. Will use my straight key and any speed is fine.

In-Reply-To: References: Message-ID: It's been 50 years since I worked in the acoustic labs at Boeing where I posed the same question. One of the specialists in the passenger accommodation section of the lab explained it this way: the human ear is a SUBJECTIVE and dynamic instrument. In other words, the perception of sound pressure level (SPL) is a function of environment, how a person feels (is the person ill or have a runny nose, etc.), the listeners temperament (is he happy or upset), the nature of the sound (does the listener like the sound or does he find it annoying), how much has the listener had to drink, etc. As for the dynamic aspect, depending on the environment, you may hear a particular sound one way but a bit differently a moment later, depending on the above factors. Another factor is that sound can be much like water leaking into a boat. Both the water and SPL increases over time depending on the opening through which the water or sound enters a space. That type of sound can be measured with instruments but difficult to assess by ear. Sound in a restaurant can be much like water in a boat, people tend to talk louder which increases the overall SPL which causes them to talk even louder. In short, the rule of thumb is that it takes about a 10 dB increase in SPL for a person to perceive a doubling in the level of the sound. 3dB is almost imperceptible with most any kind of background noise. On a tangential note, during the late 60s the Super Sonic Transport (SST) program was in progress and NASA conducted an extensive series of tests to determine objective and subjective aspects of sonic booms. The tests were conducted at Edwards Air Force Base in California over a three month period. Boeing, Lockheed, and other institutes participated. The base was building additional housing at the time so several of the new structures were used for the tests. Three of them were fitted out like regular homes with carpeting, window shades and curtains, furniture, etc., and a couple of the houses were configured more like offices or large department stores. Some of the homes had people in them and others did not. All of the buildings were extensively instrumented, both inside and out. All of my transducers were mounted on the outside of the buildings and my recording equipment was in a double garage of one of the houses. In my building, the garage door had been replaced with a large plate glass window to simulate a store front. The mounting assembly for the glass was changed from time to time to test various mounting designs. The subjective part of the test was done with people from the local communities who sat in various rooms and filled out forms designed to rate the effects of the sounds they heard. The sonic booms were generated by F104, B58, B70, and the then new SR71/YF12 aircraft. During some of the subjective tests, a KC135 (Boeing 707) airplane was used to simulate takeoff or low fly over sounds near airports. I never read the final report(s) of the tests but a few preliminary reports made the rounds. In the case of the subjective tests, people were all over the map. In many cases, people would give radically different scores for identical tests days or weeks apart. The objective tests often produced predictable results but there were times when repeat tests produced big surprises. Temperature, humidity, wind, and even doors open of closed, made noticeable differences in the measured data. For a quick look, we taped a ball point pen to the center of the large window and mounted a paper plate on the face of a clock so the plate was driven by the second hand. When the boom hit, the pen would produce a trace on the plate showing the displacement of the window. Some of the test were done with the garage being "tuned" by judiciously opening a door. A given aircraft would hit us with a boom then the door would be readjusted and the same aircraft would duplicate the boom minutes later. The difference could be startling. During one series of identical flights the first boom displaced the window 15mm but the second boom produced a displacement of 155mm. This type of testing is very expensive so, in an attempt to reduce the costs a ten foot diameter exponential horn which was mounted on a trailer. To test the efficacy of this device, the trailer was placed near one of the houses then two positive pressure pulses of gas were produced to simulate a sonic boom. The people in the house were told the boom was from an aircraft and asked to rate it in the usual way. (A sonic boom consists of a positive pressure spike followed by a negative spike. The amplitude, shape, and timing of the spike is a function of the speed and shape of the aircraft though the shape of the spike can be modified by structural and geologic features. The tests with the horn produced only positive spikes but the shape and timing could be adjusted mechanically. One day there was a lull in testing so I stepped outside for some air. Sitting on the ground a few feet in front of the horn was the neighborhood mutt. The dog must have noticed me because it cocked its head and looked at me. The image was right out of the logo for the RCA corporation.

In-Reply-To: References: Message-ID: Ted, I am not going to comment on the dB aspect, but the XYL and I have had great success in restaurants by asking the staff to turn down the music (or TV or whatever was making electronic sound). In many restaurants, it seems that the staff want to listen to *their* music over the din of patrons voices, and that only makes the situation worse. Lowering the music level will lower the overall noise level considerably. People tend to talk louder in a setting where there is loud audio background - they want to talk with their table partners over the electronic noise. I don't know how to counter the Holiday season when you have "Jingle Bells" or "Grandma got run over by a Reindeer" blasting in your ears - eat and shut up may be to only way to counter it or be branded as Grinch or Scrooge. Of course, there is always the one restaurant patron who has no concept of "inside voices" that becomes an irritant to everyone else. Choose restaurants with carpet instead of hard floors for a further decrease in ambient noise level - soft wall hangings help too. 73, Don W3FPR On 12/13/2018 12:16 PM, Dauer, Edward wrote: > A very unpleasant dinner last night at a restaurant with a reported noise level of 84 db ? about the same as a gas engine lawn mower seated at the next table ? raised what is probably an elementary question. 3 db is the familiar doubling of power, and in an audio environment is a doubling of acoustic energy, I understand.

I have a string of power attenuators followed by a step attenuator for calibration purposes.? Within its linear range the SDR-IQ is remarkably good.? This is a laborious process, sped up a little with the K3 utility and saved instrument states in SpectraVue. One nice thing about this setup is that I can actually record the spectrum display and play it back later for analysis just as if it was live.? A guy smarter than I could probably automate this; I put the numbers in an Excel spreadsheet and let do the charting. What you can find doing this is that the IMD is sensitive not only to power and voltage but to frequency.? Pick the right frequency and IMD can be -40 dBc, pick the wrong one and it's -20 dBc; same radio, same supply voltage and output power. Wes?

The ring contact of the end with the stereo jack will contact the shell (base) of the mono plug. Holding either paddle contact grounded when you power on will cause an ERR PTT or KEY ERR message. Easiest solution is to change the plug on the key to a stereo 1/8 inch plug. Connect only to the tip and the shell. You will be able to use it not only with the KX3, but also with other transceivers you might have. 73, Don W3FPR On 12/14/2018 8:18 AM, Mike Parkes wrote: > Hi everyone.

With my hearing loss the noise level just shoves everything to sound like noise with no intelligence detectable. I note that some now have cc activated on TV's with sound turned down to keep background sound lowered. That allows patrons to follow sports or news programs without everyone raising their voice to compete with the TV. Background music is just noise if I want conversation with anyone. Finer restaurants go to some lengths to produce the "quiet atmosphere" for fine dining. The restaurants that cater to twenty-something crowd seem to relish in making it loud. It really gets to me when they play loud music in the restrooms -ugh. Running the ham radio in the car or truck is challenge because I need the volume too high for my wife's comfort. Do not wear a headset as this might compromise my driving (ability to detect presence of other vehicle). But then I try to operate in the "parked mode" as distracted driving is not wise.

It will be the same port and connection that you use for loading firmware to the K3. Just tell Rumlog to use that same COM port.

Message-ID: I am interested in determining the best way to split out the KX3's receive audio for digital modes to an external speaker, so that if I want, I can listen to the band while running digital sound card modes. (Maybe I am just too old school, but my older rigs (like the IC-751a) could do this easily because they had a separate digital output for rtty and other fsk modes. So I was able to monitor the band while also decoding digital modes.) I thought I could use a splitter from the KX3 phones jack, and send one side to the PC and the other to a speaker (with its own vol control). I have no idea how that will impact the signal going to the PC though, at the least it will be less level to the PC. Or perhaps one of the USB sound card interfaces can do this, as I think some of them have their own audio out? Ideally I would also like to be able to monitor the transmitted audio signal too if possible (whatever the signal is that is leaving the PC and going to the KX3. If anyone has any advice on this I am all ears. Thanks!

RUMlog has been replaced by RUMlogNG, available through the Apple App store with a donation requested. Its been a while since I used RUMlog, but the basic setup is similar. Mine is: Use CAT checked For RTTY use Data AFSK A For PSK use Data Data A For unknown Data use PSK Serial Port Baud Rate 38400 Stop Bits 1 Parity None All the Flow Control and Power Up Lines unchecked Interface Serial For PTT use: TRS CAT These settings should get RUMlog talking to the radio. RUMlog will be able to copy the frequency from the radio, automatically setting up the entries for frequency, band, etc. It will also be able to make a good guess about the Mode of the QSO. In addition, if you use RUMlogNG, there is a useful built in contest mode that knows about many popular contests and can set up the PF keys to send canned messages. If you have any other questions, please ask. 73 Bill AE6JV On 12/14/18 at 4:19 PM, donwilh at embarqmail.com (Don Wilhelm) wrote: >Lee, > >I am not a Mac user, but the connection should be easy. >It will be the same port and connection that you use for >loading firmware to the K3.

Some came back but I have a -85 dB loss in my right ear and what I do hear is not what you hear but attenuated. Noise of any kind makes it difficult to hear and I have a pretty much world class stereo that helps greatly in hearing music but... Enter BOSE QC35 headphones... They are absolutely a Godsend when it comes to hearing. I've been using Bose headphones for years but the noise cancelling ability with these are the best yet. For computer, cell phone & TV I use its Bluetooth but for the K3s I plug in and this new generation of QC from Bose allows them to be passive or with noise reduction. As passive headphones they use no power and work just fine, they do cup the ear entirely and fit/act much like the ones I use with target practice. When plugged in, Bluetooth is defeated and when you power them on, the background sound disappears. My old Alpha is 1' from my head & on my good ear, with the Heil & Sony headsets, the fan is competing with faint signals. With the noise cancelling turned on, the fan noise is non-existent. I think I might hear the very faintest motor noise but I can't swear to it. The fan noise is totally gone. I don't think there is a microphone option when plugged in but when I use the headsets with the cell phone & I'm next to the amp, nobody I talk to can hear the fan so the noise cancelling truly works with the microphone as well. I got these from Bose as my old QC15 developed a problem and they don't repair out of production headsets but they give a generous price on a current set when you exchange your broken one. I even bought the YL a pair of the QC35 II for Christmas, they're that good. They have a 30 day trial if bought from Bose. I will say the included plug is miserably short and I had to buy a longer one from Amazon but it's a hefty cable and was inexpensive. I should add, when you turn on the noise cancelling & I'm listening to a faint CW signal, there is apparently zero loss of signal volume or quality, it's just that all the ambient sound and the sound like listening to a seashell you get with over the ear headphones just vanishes.

I took it apart and found the lock washer and nut. Figure 10 in the manual shows that there should be a spacer attached to the KXV3. The space is there on the top left mounting hole, but not the lower right one. There is no evidence that it was ever one soldered to it. My concerns are 1) Is the space still somewhere in side the radio causing very bad things when I power it up. 2) Without this spacer the KXV3 starts to flex if tightened to much an the KXV3 may short against .the rear plate. If not tightened enough it will vibrate loose again. Can anyone confirm that this spacer should have been on both mounting wholes ?

The owner's manual says: "A tune operation begins when RF power between 7 and 100 watts is applied and the SWR is above the tuning threshold in AUTO mode, or when the TUNE switch is tapped in either AUTO or MAN modes. The RF power must be below the key line hot switching limit (see Key Line Hot Switching, above) so the KAT500 can disable the amplifier. The KAT500 will not respond to less than 7 watts of drive and over 100 watts will cause a fault condition (see Fault Conditions on page 18)."? ? According to this description nothing should happen if tune is attempted with 5 W.? Why does the KAT500 fault?? (Fault code 01 No Match). Shouldn't the KAT500 either do nothing, as stated in the user's manual, or issue a fault code that indicates input power is too low to tune?

Shaking it will not normally hurt anything - if anything shakes loose (other than the spacer) If you can't find the spacer, you may be able to slide some split lockwashers between the board and the rear panel that fits over the board. Removing the left side panel will make access easier. 73, Don W3FPR On 12/16/2018 9:35 AM, mike stokes wrote: > I bought a used K3 and found that the lower right screw that holds the > KXV3t against the rear chassis had fallen out during shipping.

It has a frequency limiting component in the wire alloy that must be removed in order to use this type wire at RF. This removal procedure is fairly easy to accomplish. First, soak the wire in a bucket of laundry detergent and water over night, then remove the wire and rinse it thoroughly. After assuring the wire is dry, place in an oven set to about 150 degrees for about 3 - 4 hours. In lieu of the oven, you can also place the wire in an afternoon of summer sun. After that, place the wire on the ground and hold a 2 meter hand-held over the wire, approximately a foot away and key up the radio for 20 seconds at a couple watts output. If you see no reaction, sparking, especially tingling in your ears, or physical movement of the wire, it is now safe to use as an antenna.

So-called speaker wire (which is really lousy for speakers because it should be twisted pair to minimize RFI) has Zo in the range of 75-100 ohms. Unless it's wet, virtually all the loss in transmission lines below about 100 MHz is due to wire resistance, not dielectric loss. There is, of course, additional loss due to any mismatch that may be present, but that still comes down to loss in the resistance of the line. While I haven't measured any zip cord, I've measured a lot of closely spaced parallel wire transmission line made from THHN, enameled copper, and Teflon insulated #12 silver-coated copper. In order of loss at dB/100 ft at 10 MHz from low to high, the Teflon #12 is lowest at 0.94dB, then RG400 at 1.22 dB (about the same as RG58), then #12 THHN at 1.34 dB. #12 or #10 enameled copper had the greatest loss, 2.4 dB/100 ft. 73, Jim K9YC From KX3.2 at ColdRocksHotBrooms.com Mon Dec 17 15:05:12 2018 From: KX3.2 at ColdRocksHotBrooms.com (Lynn W.

Hi Jim, Two parallel transmission line is the easiest of all to evaluate using a RF resistance table and knowing the impedance of the line. http://ve3efc.ca/wireohms.htm The wire loss is dB = 10 * log10((Zo + WireR)/Zo) Assuming Zo=100 for the #12 Teflon and THHN. R at 10 MHz = 4.24/100 = 8.48/200. Wire dB = 10 * log10(108.48 / 100) = 0.35 dB Using the two values above at 10 MHz, 0.94 and 1.34, the dielectric loss is 0.59 dB and 1 dB. The dielectric loss is about two and three times the wire loss.

It is fascinating to set up some wires in the model, plant a source somewhere, and then look at the radiation pattern and current distributions. Having been very active in Field Day over several decades and trying out different antennas (often more than one) each year, I would be willing to bet $100 that I have physically built more functioning antennas than you have.? Analyses paralyses my ass. The point is that analysis and practice are not mutually exclusive, and anything that helps us actually understand what we do instead of blind trail and error is worth the time and effort it takes. Learning by any means is not "bad" ... it is very, very good. Dave ?

If you do the balance with a dummy load that is truly a 50 ohm resistive load ( a 1.13 SWR just does not "cut it"), then adjust the forward KAT2 pot to give you the same K2 display as indicated by the LP-100, your power should track nicely. Your K2 power output does depend on the correct calibration of the KAT2 wattmeter. 73, Don W3FPR On 12/17/2018 9:03 PM, engineercm wrote: > I'm becoming more active in QRP contesting and need to make sure that my > power is <5W.

By contrast, the KX2, which I do own, uses an 11 V internal Li-Ion (Li-FePO, I believe) battery, and is designed to provide full output at that voltage. (The KX3 requires at least 12 V.) One possibility for the KX3 would be to do as I did for my old KX1, which was to replace the internal batteries with four AA Li-Ion cells, plus a low dropout linear regulator to limit the voltage to 15 V. The batteries would have to be removed to be recharged, and a second set would be required for longer operation. The scheme works well with the KX1, and I can't think of any reason it wouldn't work with the KX3. Obviously, an external battery pack of 4 larger cells could be used the same way. Of course, the usual safety precautions must be taken, as with any Li-Ion batteries, and there could be warranty issues. That said, I expect KX3 owners would appreciate it if Elecraft offered an internal Li-Ion battery for the KX3. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From clark.macaulay at gmail.com Mon Dec 17 21:46:58 2018 From: clark.macaulay at gmail.com (Clark Macaulay) Date: Mon, 17 Dec 2018 21:46:58 -0500 Subject: [Elecraft] K2 Power Control Question In-Reply-To: <31a8f145-6a5b-4995-20da-6363fa3617a2@embarqmail.com> References: <1545098606804-0.post@n2.nabble.com> <31a8f145-6a5b-4995-20da-6363fa3617a2@embarqmail.com> Message-ID: Ahhhh......

You can always use an external power supply or battery pack of up to 15 volts to provide full 12 watts output.

If your desire is to obtain the horizontal and vertical radiation patterns, then modeling is the best way to do that. If you want to cut only once, use the technique I had published in QST Technical Correspondence May 2018. Cut the radiator to 468/F(MHz) plus 5 or 10%. Measure the radiator length and put it in position. Then with your antenna analyzer, measure the resonant frequency in MHz. Now multiply the actual frequency times the length to find a new "cutting factor" (will be different than 468). Divide that new 'cutting factor' by the desired resonant frequency, and then trim the antenna to the new length - put it up and it will work. Remember that the resonant frequency is where the "X" component of the antenna is zero - it may be the same as the lowest SWR, but not necessarily so. 73, Don W3FPR On 12/17/2018 9:56 PM, Fred Jensen wrote: > Yes, to each his own.?

Connect both wires for a fat dipole. But, be careful. The phone company uses a device on the end that attaches to the house that is a break-away in case a tree, etc falls across the wire. The stuff is so strong that it will pull the siding off your house. I knew of someone who used it in a community with C&R restrictions. He requested that he could put up a dog run. The dog run was actually his antenna. When asked why the dog run had a wire going to the side of his house and ground, he replied "lightning protection". He didn't want his dog electrocuted during a storm.

There's the usual rain, insects, and insomnia of Field Day, of course. Murphy at his best. But our customers have gone well beyond this, conquering uncharted territory, experimenting with new technology, even recruiting diminutive ungulates as pack animals. Feedback about these experiences has helped us hone our ultraportable transceivers; they've gotten smaller, lighter, and more capable, leading to the present KX3 and KX2. We've also answered the call for a truly compact, multi-band pedestrian mobile antenna with the introduction of the AX1 and its accessories. No doubt -- with your help -- our gear will continue to evolve. Tell us about your operating adventures. And misadventures. What worked best? Where could things have been improved? For example, when you were clinging to a tree limb using an inverted vertical last winter, could you still hear signals above the blizzard? On that ironman run, did you need an antenna that deploys with one hand? Maybe an integrated speech-to-FT8 converter? And when you embellish your tales beside a campfire, should your detachable keyer paddle double as a bottle opener? A few of your stories will find their way into our monthly newsletter. All of them will help inform and inspire the next generation of Elecraft's outdoor product line. 73, Wayne N6KR From jim at audiosystemsgroup.com Tue Dec 18 13:54:00 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 18 Dec 2018 10:54:00 -0800 Subject: [Elecraft] Opportunism, bravery, insanity: putting the "eXtreme" in Elecraft's KX and AX gear In-Reply-To: <628725D3-3443-4E24-9C07-B7C6616F7888@elecraft.com> References: <628725D3-3443-4E24-9C07-B7C6616F7888@elecraft.com> Message-ID: How about KH6JF/MM? https://ae5x.blogspot.com/2018/03/hf-voyager-ocean-going-drone-with-kx3.html 73, Jim K9YC On 12/18/2018 10:41 AM, Wayne Burdick wrote: > Tell us about your operating adventures.

Although I've never done the design work for them, I suspect that bandwidth can be increased by careful design of the matching networks. Technical details of US broadcast antenna systems can be queried from this link. https://www.fcc.gov/media/radio/am-query > All resonance means is that the reactive component of the impedance at > the feed point is zero.?

And it's an even bigger problem for stations using directional arrays! Those arrays are required by the terms of their license to protect other stations on the same or adjacent channels from interference. As a college student, I worked for one of those stations, and later for a consultant (Pete Johnson) who designed those arrays. Pete and Carl Smith wrote the technical sections of FCC Regs for AM BC after WWII. 73, Jim K9YC From jthorpe at liberty.edu Tue Dec 18 16:43:37 2018 From: jthorpe at liberty.edu (Thorpe, Jeffrey) Date: Tue, 18 Dec 2018 21:43:37 +0000 Subject: [Elecraft] Opportunism, bravery, insanity: putting the "eXtreme" in Elecraft's KX and AX gear In-Reply-To: References: <628725D3-3443-4E24-9C07-B7C6616F7888@elecraft.com>, Message-ID: Since the KXPD3 has two paddles, why not a bottle opener on one, and a can opener on the other?

There were a few Class A's on the coasts that did use directional phased arrays since there weren't many/any listeners out at sea but I don't know if any of them are left.? Non-Class A's generally employ 2 or sometimes 3 phased verticals to achieve directional patterns at night to protect co-channel stations, putting null(s) in the direction of their service areas. Class A's, such as KFI, seek to maximize the coverage in their service area [i.e. maximize the area covered with an adequate field strength].? Neither a 90-degree vertical ... current max at the bottom ... nor a 180-degree ... current max half way up the tower ... will do that.? At 640 KHz, a half-wave is ~730 ft. The obsession with VSWR in ham radio is a bit surprising.? I can't really remember when the term became common, or when I first saw a VSWR bridge, but I do know that I never saw one in SE Asia in the mid-60's.? These days, high VSWR seems to equate to "antenna that doesn't work." 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 12/18/2018 12:38 PM, hawley, charles j jr wrote: > Interesting, I had an analog computer course exercise at the U of I Urbana when we had two verticals separated and phased to define the coverage pattern.

It does have a lot to do with the ability to match the feedline to the transceiver which normally likes a 50 ohm load or something close - but then an ATU can take care of that situation easily. Often a feedline is used as a matching section, and the reason it works is that SWR makes it work. See the antenna and feedline article on my website www.w3fpr.com. 73, Don W3FPR On 12/18/2018 5:43 PM, Fred Jensen wrote: > > The obsession with VSWR in ham radio is a bit surprising.?

Theoretically 225 degrees would yield the most radiation towards the horizon but presents two problems. The first (for class A stations) is the secondary lobe that causes self interference skywave. The second issue is self loading where the radiator is longer electrically than it is physically. In such instance a 225 degree radiator is actually electrically longer causing the main lobe to lift off the ground and break into additional sidelobes. For that reason, class A stations opted for a compromise height of about 195 to 200 degrees. This lowers the base impedance over 180 degrees while limiting secondary skywave lobes to an acceptable level and staying in a safe area as far as self loading is concerned. Some class C (former class IV) stations use 225 degree radiators, though. Bandwidth is partially a function of the size of the tower face and also the design of the matching network. The problem becomes challenging when radiators get down around 60 degrees. There are two directional class A stations I can think of - WBZ Boston and WWL New Orleans. Both are very much alive and well and still quite successful.

Non-Class A's generally employ 2 or sometimes 3 phased verticals to achieve directional patterns at night to protect co-channel stations, putting null(s) in the direction of their service areas. > > Class A's, such as KFI, seek to maximize the coverage in their service area [i.e. maximize the area covered with an adequate field strength].

If you want to go back to those "good old days", build yourself a link coupled tuner. It will likely use plug-in coils and perhaps a swinging link. Then you can tune it just like you did on your old transmitter/amplifier - except you do not have to "dip the plate" and change the link coupling to bring the plate current up to where you want. You adjust that tuner so you have a low SWR at the input. If you can't get a low SWR, adjust the transmission line taps on the coil and try again until you get it right. Each antenna requires different coil taps and different tuning. Tune up and band to band QSYs were not quick and easy in those days. Those who wanted instant band hopping had multiple amplifiers each with their dedicated antennas (rich hams) - now we can have that same capability with a single multiband antenna and an ATU. While I do have a couple of those tuners (with their wide spaced "bread slicer" capacitors) in my collections, I prefer to use the newer ATUs - push a button and it finds a match. The old methods are not better or worse, but just different. Newer stuff does it easier - but it is interesting to know what is happening in the stuff that does the impedance transformation. Engineers know the concepts, and older hams know what is involved even if they do not understand the theory. It seems that many newer hams do not care - push the button on the microphone and make a contact is the limit of their interest. Perhaps we need to launch a renewed effort in bringing newer hams into the fold of understanding what is going on other than pushing the PTT button on the microphone. I hate to see the ranks of ham radio descend into the same category as CB operators, but I think we are headed that way as far as understanding what is involved in RF transmission and reception. If you want a computer parallel (for those digitally inclined) it is the difference between someone who only wants to do email and web surfing and those who understand (or attempt to learn) networking and how all that fits into the World Wide Web and Internet of Things. We do not have to fully understand propagation, circuits, antenna theory and such to push that PTT button and talk, but if that is all you do, it is more akin to CB than it is to amateur radio. OK, I will crawl off my soapbox for the time being. 73. Don W3FPR On 12/18/2018 8:00 PM, Fred Jensen wrote: > Yep, the term was known when I became KN6DGW in 1953, but somehow no one > cared.?

This is completely due to broadband design. This can be solved by including an ATU as is done with a number of Elecraft products either as an option or a feature.

Right now it's still in the early days of release, but it's getting better and better, and they plan on a complete micro workstation for digital operations. It has lots of the features you would need. It's not quite to the point of just plugging it into the left side of a KX3, but that's probably something some enterprising engineer could cobble up as an adapter, or a 3d printer project. I've got one of the boards, I've just been waiting for the developer types to find all the flaws and figure out all the additional bits necessary to make it truly complete before I dive into it. Besides, I'm in the middle of relearning my code, so I can use CW again! I was a CW operator back in 2000, but I let it slide and haven't used it in a long time. So I need to relearn it! Here's the website. There's also a mailing list on groups.io if you need more information. http://nwdigitalradio.com/draws/ 73, Gwen NG3P On Tue, Dec 18, 2018 at 8:54 PM Keith Onishi wrote: > A small box, which consists of a Linux computer with WSJT-X and Bluetooth > capable to communicate with smartphone applications, attachable to the left > side of KX3 without connection cables would be nice.

A way to evaluate is to measure a length of speaker wire and compare to an air dielectric equivalent. Here is an example: https://www.kn5l.net/SpeakerWire/ The Air dielectric equivalent model is for #18 with spacing for a Zo match with the speaker wire, 117 Ohm. Note that at 10 MHz, the speaker wire loss is over three times the air dielectric equivalent. A DC resistance of the speaker wire suggested that the wire size is actually closer to #19. Tough measuring these very low DC resistances, so decided to assume #18 for the air dielectric model. The speaker wire loss and Zo used a Zoc and Zsc data set. There are links to the two files for verification. Check my math!

It appears that as I transmit, current consumption increases, and I get occasional high current messages. This is more apparent on long duty cycle modes like RTTY, and at higher power levels (80-100W). If I watch, I can see current consumption start at 16 amps, and slowly rise to 25-27 amps. I performed a TX gain Cal successfully, and that made it a bit more stable (only rising to 20 or 21 amps now), but it still concerns me. A friend suggested this may be blown coils in the output bandpass filters. I can wrap new coils if needed, but don?t want to do this if that?s not the problem. 73 Harv K2PI Sent from Mail for Windows 10 From: Don Wilhelm Sent: Wednesday, December 19, 2018 9:44 AM To: Bob Harvey - K2PI; elecraft at mailman.qth.net Subject: Re: [Elecraft] k3 High Current Message on 10 meters Harv, I did not see the initial post (fault of Nabble vs. the real Elecraft reflector), but High Current messages can be caused by a low impedance at the antenna connection, or also a fault in the KPA3, like one output transistor that is no longer functioning properly.

Also, built-in Free-DV support would be really nifty, for all the K-line. This is starting to show up in certain competitive radios. Thanks for asking. 73, -- Dave, N8SBE -------- Original Message -------- Subject: [Elecraft] Opportunism, bravery, insanity: putting the "eXtreme" in Elecraft's KX and AX gear From: Wayne Burdick Date: Tue, December 18, 2018 1:41 pm To: Elecraft Reflector , "KX3 at yahoogroups.com" Since the beginning, Elecraft products have been used under difficult field conditions. There's the usual rain, insects, and insomnia of Field Day, of course. Murphy at his best. But our customers have gone well beyond this, conquering uncharted territory, experimenting with new technology, even recruiting diminutive ungulates as pack animals. Feedback about these experiences has helped us hone our ultraportable transceivers; they've gotten smaller, lighter, and more capable, leading to the present KX3 and KX2. We've also answered the call for a truly compact, multi-band pedestrian mobile antenna with the introduction of the AX1 and its accessories. No doubt -- with your help -- our gear will continue to evolve. Tell us about your operating adventures. And misadventures. What worked best? Where could things have been improved? For example, when you were clinging to a tree limb using an inverted vertical last winter, could you still hear signals above the blizzard? On that ironman run, did you need an antenna that deploys with one hand? Maybe an integrated speech-to-FT8 converter? And when you embellish your tales beside a campfire, should your detachable keyer paddle double as a bottle opener? A few of your stories will find their way into our monthly newsletter. All of them will help inform and inspire the next generation of Elecraft's outdoor product line. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to n8sbe at arrl.net From donwilh at embarqmail.com Wed Dec 19 12:58:07 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Wed, 19 Dec 2018 12:58:07 -0500 Subject: [Elecraft] K2 with KPA-100 In-Reply-To: <68128b5f-57bb-2ba9-75bc-1fbf1b201a1c@comcast.net> References: <68128b5f-57bb-2ba9-75bc-1fbf1b201a1c@comcast.net> Message-ID: Gene, Look at the top of the K2 - does it have a black finned heatsink? If so, that is the KPA100. If you have 2 BNC connectors at the ANT1 and ANT2 positions on the upper rear panel of the K2, then the KAT2 is installed. BUT the KPA100 and the KAT2 cannot co-exist since they occupy the same physical space. Is there something you are not telling us - like is the KPA100 mounted in an external enclosure? In any case, even if you do have the KAT2, it will be automatically bypassed and set to ANT1 if the KPA100 is detected. The ATU must be located between the PA and the antenna - so you need the KAT100 if you are using the KPA100. Having an ATU at the input of the amplifier does no good because the amplifier input should present a 50 ohm load to the exciter. 73, Don W3FPR On 12/19/2018 11:11 AM, Gene O wrote: > For a portable operation: > > Can anyone tell me if I have a K2 with the KPA-100 and the KAT2 low > power auto tuner installed can it be operated at say 35 watts.?

Normally I do not run any analog digital mode at 100 watts due to a bit of compression that appears to occur in the PA stage. ? ? My suggestion, as I do, run 50 to 75 watts with analog data. Likewise with the KPA500, about 300 to 400 watts max for analog data signals. In working SSB do you get reports of "fuzzy audio" or with PSK-31 get reports of poor IMD ??

Ah, but the phaser (matching networks) for AM broadcast directional arrays usually is located at or near the transmitter - or at least they were when I dealt with AMers in the 1960s-1990s. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From nr4c at widomaker.com Wed Dec 19 17:21:35 2018 From: nr4c at widomaker.com (Nr4c) Date: Wed, 19 Dec 2018 17:21:35 -0500 Subject: [Elecraft] k3 High Current Message on 10 meters In-Reply-To: <123c848a-c1d6-bb30-37cf-7c56baca4be9@blomand.net> References: <4F5571C5.50905@km5ps.com> <1545229805572-0.post@n2.nabble.com> <237d8dcc-ce28-30a5-a56a-280a7a68a4af@embarqmail.com> <5c1a5b7e.1c69fb81.7a6a.bd36@mx.google.com> <2eb07792-099d-48a6-fce5-070b0c1315c3@embarqmail.com> <5c1a5ec0.1c69fb81.4bf13.0ec0@mx.google.com> <168dfb03-667a-ca42-9b86-8a097fb2acda@blomand.net> <003701d497b8$b592a410$20b7ec30$@net> <123c848a-c1d6-bb30-37cf-7c56baca4be9@blomand.net> Message-ID: If you?re using a BALUN is it saturating or ha anything changed in your antenna system?

My suggestion, as I do, run 50 to 75 watts with analog data. Likewise with the KPA500, about 300 to 400 watts max for analog data signals. > > In working SSB do you get reports of "fuzzy audio" or with PSK-31 get reports of poor IMD ?

Regarding the improvement, almost every internal component has been upgraded from new or existing suppliers. The burn in time has been tripled and the reliability is now at a .001 failure rate.

In other words, the KAT2 will not work with the KPA100 present. If an ATU is required with the KPA100 in-line, the KAT100 or other ATU between the KPA100 output and the antenna is necessary. Yes, the KAT2 is rated at up to 20 watts. The KAT100 is rated at up to about 150 watts. 73, Don W3FPR On 12/19/2018 11:24 PM, Brian Denley wrote: > ..unless you build it in the ?Twins? configuration.

The USB SD card reader may be different (I just don't know). While there is space in the computer to handle drivers for an SD card reader, the PX3 is more limited in its capability, the support for flash drives must be coded in firmware. 73, Don W3FPR On 12/20/2018 6:25 AM, Mike Parkes wrote: > Hello group, happy holidays! > Hey I am trying to get the PX3 working with a usb sd card reader (which > works fine on the pc)... and when I plug this into the USB port on the px3 > the display just freezes up, no "M" appears on the display.

But you can try it and see if the no-load voltage goes too high - move the tap back if it goes too high. Your problem is likely with the voltage drop on the 120 volt line. Is the receptacle shared with other receptacles in the house? If so, they should all be checked for tightness of the wires to the receptacles. If any use the "back-stab" connections, they should be changed to the screw terminals. If you are not qualified to do those checks, have a licensed electrician do it for you. If you can see your way clear to run a dedicated 120 volt receptacle into the area where the amp is located, that will help - have it wired with #12 or better #10 wire for the lower voltage drop. 73, Don W3FPR On 12/21/2018 5:58 AM, eric norris via Elecraft wrote: > My KPA500 used to be on a 220v line, but it is now in an area where that is not possible.?

It was was killed by a lightening strike because some moron operator forgot to unhook, and then forgot about it... Building this equipment has been the most fun I've had in this hobby, and it's incredibly gratifying when they come to life. Each one had its own unique "teething pains", but they were minor, and were quickly solved with the help of Don and many others on this list. I even figured out a couple of problems on my own! Electronics is a hobby, and was not my chosen profession - although I had a lot of exposure to many kinds of diagnostic and test equipment, and I did know how to properly solder and read a schematic. The kits are beautifully designed, with almost no point-to-point wiring, and the manuals are first-class. So, I just finished the KPA100/KAT100/EC2 kits that had been living in my closet for about four years, and the rigs are configured as the "K2 Twins". Even with my crummy antenna situation (which hopefully will have improved after the holidays), I've been getting some decent reports. Unfortunately, the EC2 enclosure is no longer available, so a future KPA100 will have to be mounted to the K2, and that does not allow the use of the KAT-2 tuner, but you could roll your own enclosure to get the "Twins". In that configuration, the K2 can have the KAT-2 installed, although I have two top covers and am currently using the unpopulated one with only the KIO2 and speaker installed. If you like to build, go for it! 73, Jim KO5V From forums at david-woolley.me.uk Fri Dec 21 15:33:26 2018 From: forums at david-woolley.me.uk (David Woolley) Date: Fri, 21 Dec 2018 20:33:26 +0000 Subject: [Elecraft] K2 with KPA-100 In-Reply-To: References: <9241f45e-5b95-77aa-bba7-993948fa60e5@comcast.net> Message-ID: <67de5ed7-be6d-f0bc-6813-a7abc359322e@david-woolley.me.uk> Unfortunately the KAT100-2 doesn't seem to be available any longer, even though it is still described on the man page for the tuner.

The problem is that the EC2 enclosure is no longer available. The supplier is no longer in business. Fortunately, there is a "cure" (even if it is only temporary - until Elecraft runs out of the panels). Elecraft still has some KAT100-2 front and rear panels available, and one can make up the rest of the enclosure with metal panel parts from the K2. As far as other non-metal parts to be added to the KAT100-1, there are only 3 headers. If anyone wants to go that route, I can provide a list of parts to purchase. 73, Don W3FPR On 12/21/2018 3:33 PM, David Woolley wrote: > Unfortunately the KAT100-2 doesn't seem to be available any longer, even > though it is still described on the man page for the tuner.

I was kind of taken by surprise. Two years ago I decided to leave my K2 as is with the amplifier installed. The KX2 kind of made a QRP only K2 obsolete. So I bought another KAT100 because I thought the K2 and accessories might be discontinued. I'm glad I was wrong. The KAT100-2 kind of got forgotten about. Building a K2 is an experience I highly recommend to anyone. But, most especially to anyone just getting their feet feet in ham radio. There's no better feeling in this hobby than making contacts with a K2 that you built yourself. Personally I wish there was a K2 Mark 2. But, I also wish there was a K4! Maybe someday! Over the years I have built pretty much every kit with the big "E" name on it multiple times. 5 K2, 3 K1, 3 KX1, etc. The one big confidence builder when tackling complex kits is Elecraft's support and most especially a guy named Don who has bailed me out several times when I really goofed - like putting a transistor in backwards. So, really, even if you really goof up bad, someone, such as Don, will get you through it. 73, Doug -- KJ0F From w2xj at w2xj.net Fri Dec 21 20:40:00 2018 From: w2xj at w2xj.net (W2xj) Date: Fri, 21 Dec 2018 17:40:00 -0800 Subject: [Elecraft] AM Broadcasting In-Reply-To: References: Message-ID: There aren?t many 12 tower arrays out there.

It is a bandswitching version of the old plug-in coil tuners. The matching range is not as great as that with the plug-in coils with movable taps on the coil, but it is quite useful even with the more limited matching range. Yes, it provides a bandpass response which keeps out 'crud' from bands other than the one to which it is tuned. The high pass filter of the "T" network tuner or the low pass filter of a "PI" network cannot provide that same filtering. Our local club has used fixed bandpass filters for the last 3 years with a great improvement in station to station interference. The first year, the 40 meter bandpass filter did not work as planned, and my Johnson Matchbox was used in its place and did a fantastic job. I admit, I am enslaved by the convenience of the Elecraft "L" network ATUs, and I have not evaluated the comparison of receive noise with a bandpass type ATU or filter. I am fortunate to have a relatively low noise location for my station. I cannot comment on the "RF-in-the-shack" aspects, but the balanced Johnson Matchbox likely presents a better balanced load to your antenna with parallel transmission line than any unbalanced tuner with a balun. 73, Don W3FPR On 12/22/2018 12:03 AM, Victor Rosenthal 4X6GP wrote: > I just replaced my single-ended T-network tuner plus balun with a > massive old Johnson Matchbox.

From what you say, I infer that you are using the KW version, mine is the 275 Watt unit. I believe they used similar designs. One of the things I sort of recall is that it was really a balanced feed antenna tuner that could be used for unbalanced load tuning. And yes, it was high Q meaning it was useful, sort of, for some filtering. However, the final amplifier output circuit in the Johnson gear of the time was a pi network which is useful as a low pass filter. And in those days low pass filtering was important and the antenna tuner was important for its intended design, matching only. Tuner efficiency was important as there could be a lot of heat as AM, full carrier, was the mode of the day, unless you ran CW.

My measurements, as well as circuit simulation, show about a 40 dB rejection of AM stations when the tuner is tuned to 40 meters. Circuit simulation of the Johnson circuit shows not all that high a Q, but it certainly is starting to look like a broad bandpass response. (It's actually? more high-pass than band-pass.) That's why it's effective against the broadcast band. It's yet another argument to use a tuner like that one. Interestingly, I just moved from a link-coupled tuner back to an unbalanced tuner with balun because my measurements of common-mode current on the transmission line show that the balun is more effective at suppressing it. The link-coupled tuner acts more like a voltage balun which would be okay if the antenna were inherently balanced, but in many cases the current balun suppresses common-mode better when the antenna is in an environment that makes it not well-balanced. When power lines or houses or cars or other things are in the antenna's near field it tends to make the antenna present an unbalanced load to the transmission line. That's when equal currents (not voltages) work better. But I'm repeating what has long been known. If you can measure this stuff, like with an RF current meter, it becomes much clearer. Enjoy your new, cleaner reception, thanks to that tuner! Al?

When I used a vertical antenna without a tuner, it was enough to overpower the bias in the K3?s T/R switch and generate spurs all over 40 and 30 meters. I fixed it with a highpass filter before changing to a horizontal antenna . When I rotate my dipole, there is a point where one end gets close to a structure. The tuning changes, so I know it has an effect, which must unbalance the system. Maybe coincidentally and maybe not, local noise increases at that point. I think I will try isolating the tuner from ground and feeding it through a balun.

If so, the simplest way to do data modes, and particularly WSJT-X, is to run the digital program in the computer at the radio site and control it using remote desktop software. In WSJT-X modes you don't need to listen to the audio, you don't need access to the radio's front panel, and by doing the digital encoding and decoding at the radio site you avoid any potential issues with Internet latency and jitter. You can either run WSJT-X stand-alone controlling the radio directly, or you can use Commander to control the radio and have WSJT-X use Commander for rig control. In CW and SSB you do need audio transport over the Internet as well as front-panel control (the big tuning knob, in particular) and in CW you will likely want a paddle at the control site as well. The RRC boxes do a great job with all of this. You can configure the virtual serial ports in the control-site RRC box to provide CAT control and a Winkeyer port for a copy of N1MM+ running at the control site. In this configuration you do not need a PC at the radio site, unless you need one for controlling other devices (rotor, amp, antenna switches, equipment power on/off, etc.). Or, if there is a computer at the radio site you can configure the radio-site RRC box to provide CAT control and CW keying access to a copy of N1MM+ running at the radio site and then control that copy of N1MM+ using remote desktop software. 73, Rich VE3KI AE4ED wrote: Before attempting to set up remote using K3s/0 and RRC-1258 MkII, I was using DXLab Suite and WSJT-X just fine on my K3s.

Powered speakers are historically very RFI susceptible, even high priced ones made for pro use and for the high futility world. I would also be quite concerned about RF noise produced by their power supplies, which are almost all switchers. 73, Jim From donwilh at embarqmail.com Sat Dec 22 18:11:08 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 22 Dec 2018 18:11:08 -0500 Subject: [Elecraft] K2 100 Tuner question In-Reply-To: <4b150fa8-05b5-9db2-0ba5-c1e0b313235b@kj0f.com> References: <4b150fa8-05b5-9db2-0ba5-c1e0b313235b@kj0f.com> Message-ID: <9c24a7f2-44c1-5144-fda5-793cd0c63c3a@embarqmail.com> All, Once again, the EC2 was discontinued because the metal supplier is no longer in business. To find another vendor is out of the question. The startup and tooling costs would be excessively high for the projected quantities involved. How many EC2 enclosure could Elecraft sell at a price point of $250 or more per unit (my guess, not anything official from Elecraft)? It was not a high sales volume unit where such startup and tooling costs could be swamped out by the sales volumes. 73, Don W3FPR On 12/22/2018 4:44 PM, Doug Person wrote: > > On 12/22/2018 2:30 PM, Rick Wheeler wrote: >> I always wondered why Elecraft discontinued the EC2 enclosure.

Both times, I found that when I tuned my K3 to a signal peak in the P3 display, there was no sound in the headphones.? When I tuned 900 Hz past the peak I found the signal.? This was a little embarrassing last night, because I issued a spot via DX Summit that was 900 Hz off from later spots on the same station put out by others. I found that the error could be corrected by turning the sub receiver on, putting the K3 in split mode, then going out of split and turning off the sub receiver.? This problem may be associated with my habit of putting one VFO in CW mode, and the other in Data mode at one of the FT8 frequencies.? The problem seems to come up when I turn off the WSJT-x program. My K3 has the latest firmware installed (5.66); I am using DXLab's Commander v. 13.8.1, and WSJT-x v. 2.0.0 . I'd appreciate any hints about what I may be doing wrong.

But there's only so much any tiny amp can handle. I actually found a pair of super efficient non-amplified speakers meant to work off a headphone output. Not a lot of volume. But a lot more than the built-in. I also built a small speaker enclosure using a plastic utility box with 2 1.25" Mylar speakers driven by one of the now highly common tiny amplifier boards. I shielded and beaded everything.

Small volume parts like this would be cut on a laser and bent with a CNC press brake. The only setup is loading the programs and there is no tooling. If someone draws the parts using a CAD program like Solid Edge, the resulting 3D models can be utilized directly by the vendor. Even small job shops have laser cutting ability, especially for small gauge material like this. Hard tooling would only be used in high volume (thousands at least) for a very cost sensitive project. I'm not familiar with methods prior to the '80s, but even back then this would be done on a turret punch press. You'd only need tools for oddball shapes the vendor didn't have, and those are fairly inexpensive. For small runs you'd have the setup time of loading tools into the turret, but as noted, that no longer exists. 73, Josh W6XU Sent from my mobile device > On Dec 22, 2018, at 5:15 PM, Don Wilhelm wrote: > > Josh, > > The stuff needed to punch the panels out of a piece of aluminum and put the holes in the right place.

One generally tries to tune them for minimum Q to minimize losses. If tuned to a high Q, however, both the T and pi networks generally will provide some rejection of adjacent frequencies. Just how much is impossible to predict, unless you know just how the antenna impedance varies with frequency. At far removed frequencies, of course, a T does act like a high pass, and a pi like a low pass, but in neither case do they match the antenna to 50 Ohms, unless it happens to actually be 50 Ohms at some frequency. That said, is suppose it IS possible that a tuner/antenna combination just happened to have a deep null right on the frequency of a nearby broadcast station which was causing intermodulation. If that were the case, a more reliable solution would be a trap or stub. 73, Scott K9MA On 12/22/2018 08:52, Bob McGraw K4TAX wrote: > The Johnson Matchbox configuration is indeed a banpass filter meaning > it attenuates both above and below the frequency to which it is > tuned.???

Now you're just making things up. I just had some structural brackets made. They had 18 holes, laser cut and bent from 3/8" thick 304 stainless. They were $45 ea for 13 pcs. Supplier did the CAD for me from my pencil sketch. Took him less than 10 minutes, no extra charge. A little difficult to extrapolate from that example, other than to note the very low volume, it's expensive material and slow to cut. 73 Josh W6XU Sent from my mobile device > On Dec 22, 2018, at 7:03 PM, Don Wilhelm wrote: > > Josh, > > I may not be up to speed, but there are startup costs for anything.

Link coupled tuners can also, of course, be inherently balanced. I've never been a fan of using baluns with single-ended tuners to feed unmatched balanced antennas, because it's just about impossible to build a practical balun that can cover the whole range of possible impedances. Open wire can operate with a 10:1 SWR with modest losses, but the impedance at the tuner could be anywhere from 45 to 4500 Ohms. The problem with link coupled tuners is that tapped coils are cumbersome and somewhat dangerous. The differential capacitor in the Johnson Matchbox was a way around that, but it was expensive and limited the range of the tuner. 73, Scott K9MA On 12/22/2018 21:20, Al Lorona wrote: > No, not a null, but a rolloff.

The network Q is set only by the two impedances to be matched. (I did once contrived a situation where matching the very low R, high C gate impedance of an FET could be done with lower loss using a series pair of L networks, but this is unusual.) In correspondence with Dean Straw 20+ years ago when we were prepping my article on ladderline, I pointed out to him that the problem with T networks with three variables was that there are an infinite number of solutions, with only one giving the lowest loss and some giving huge losses, with the operator being clueless. I believe the same would be true with the Match Box. ? (By what I'm sure must be coincidence, it was shortly after that an ARRL favored author wrote article on tuner losses.) Any rejection due to an antenna matching system is just serendipity and depending on it for that purpose is foolhardy, IMHO, of course. To pick one nit with Scott, a pi-network can be high pass and a tee-network can be low pass. Wes?

FIXED In-Reply-To: References: Message-ID: <84e0383b-9448-42d1-65df-15166b749ac5@googlemail.com> Right.. Not exactly the usual done thing, answering ones own question, but here goes... ~ ~ ~ I had previously performed:- ??? $ sudo apt-add-architecture i386 as recommended elsewhere.? However that was not enough. I found I also needed:- ??? $ sudo apt install ia32-libs-multiarch That pulls in a huge number of 32 bit compatibility libraries, and enables "multi architecture support". Now, the Elecraft XG3 and KX3 utilities run as advertised on this 64 bit Linux Mint 19 system. (Based on Ubuntu 18.04 I believe.) Well, they work OK, but there is a warning shown when launched from a command line. (xg3util:1328): Gtk-WARNING **: 10:56:10.065: Unable to locate theme engine in module_path: "adwaita", That's one for the developer to figure out I suspect.? This system uses the "Cinnamon" desktop. Note!? The leading $ in the above command line examples, just signifies that the command was entered into a terminal command line.? "sudo" is needed to temporarily elevate oneself to "Root" privileges, as what is needed, needs to be placed deep within the system, where ordinary users cannot (usually) write to.? (The password it asks for, is your usual login password.) Hope the above helps someone else. FYI: Using the file command, will show you what sort of executable the program is. $ file ./xg3util ./xg3util: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.0, stripped Using the ldd command:- $ ldd ./xg3util ??? linux-gate.so.1 (0xf7f35000) ??? libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7f05000) ??? libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf7ee6000) ??? libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf7d60000) ??? libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7c5e000) ??? libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xf7c40000) ??? libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7a64000) ??? /lib/ld-linux.so.2 (0xf7f37000) You can now see the linkages (for example) between libc.so.6 as requested by the program, it now points at the same name library in the /lib/i386/i386-linux-gnu/ location. In both the above examples, those commands were run from a terminal session, while located in the folder where the xg3util program resides, hence the preceding ./ before the filename. 73 ???

Many of you may never had done a small volume production. I have. I cannot afford to purchase CNC tooling, metal brakes, etc. for a project of twelve copies. Vendors are all out of state with added shipping costs. So I chose a good quality commercial chassis from Hammond and built an aluminum jig to hold it in a vise for drilling. Square holes required hand filing. Stick-on labeling. I used a pcb made by a reputable small production house (W6PQL). Those that bought the 80w 2m amp got a pretty good product but no confusion that it was hand made. Costs were hard to get competitive with commercial amp mfrs but I think the reliability might have been better. You would have to survey my customers who all read this list and most have Elecraft radios that were used with the amp (majority had the KX3-2M). I had an opportunity to buy out a popular line of transverters and recently a popular preamp maker. Cost/labor time were decisive against them (mostly at my age).

When you are a doing it as a hobby, you may not count the cost of that design element. For a manufacturer, it means a lot more that getting a part in-hand. Engineering prototypes are one thing, getting a product out for production sales is entirely a different matter. If you are a manufacturer, there is a big difference. You have to count the cost of Engineering Change Orders, vendor negotiations, re-designs to meet the requirements of the particular vendor you are dealing with, and finally creating a Bill of Materials and stocking and inventorying the product, and creating sales data (even if it is a re-vamped product). In other words, all the relevant pieces of your organization have to have the information needed to work in lockstep with each other. And most of that effort is in-house and takes up much of the staff resources. A one or 2 person shop can do it more quickly and easily, but in a manufacturing evironment, all the "T"s must be crossed and the "i"s dotted if you are going to succeed with a product that is only a small piece of your product line. 73, Don W3FPR On 12/23/2018 11:19 AM, W2xj wrote: > Times have changed. 3D printing permits one off runs with little effort after the initial design. > > Sent from my iPad > >> On Dec 23, 2018, at 8:00 AM, Edward R Cole wrote: >> >> Have to agree, in principle, with Don. >> >> Many of you may never had done a small volume production.

While you may be describing the 20th century method for large scale manufacturing, it has little to do with today?s technology. To begin with, Elecraft is a small low volume operation. I doubt they go through all the processes you describe. In any event the discussion began being about a relatively small case that was low volume in the first place. They could put the existing drawings on line and let the ham community take it from there. On a vastly larger scale, the auto industry is moving towards 3D printing parts on site and cutting out all those middle men (along with import and tariff hassles).

I purchased a badly-built and fried XV144 several years ago (I got it really cheap). The builder had shorted leads 1 & 2 of T1 above the PC board, and during initial testing, I think that caused a burned a trace on the board. The adjustable cores of L15, L16 and L17 were driven to the bottom of the inductors, and were broken from contacting the board. I removed all of the XV144-specific parts including the SMT stuff, and replaced them with the correct XV50 parts. I repaired the trace and re-wound T1, and checked that each component was correct and properly installed. I also tested all of the active devices. I then re-soldered every joint. It looks pretty good now, but I hope the processor isn't also ruined from the smoke test. Here's my question: in the XV144 and XV222 sections of the assembly manual, Q1 is installed with long leads, standing above the board. The XV50 instructions do not mention this. Should I re-install it in the usual way (close to the board), or leave it. Also, can anyone tell me the reason for elevating it in the other XVs? That seems like a good way to pick up noise to me, but a lot of you have forgotten more than I know about this stuff...

Likely for LO stability, and better separation from the ground plane on the board. I believe it should work mounted the same way in the XV50. If you find LO instability, then mount it down on the board. If you scraped the paint from all panels where they contact the 2D connectors and the output jack, there should be little noise conducted to the inside of the transverter. 73, Don W3FPR On 12/23/2018 1:30 PM, Jim KO5V wrote: > First, Happy Holidays to everyone, and thanks for all of the helpful advice over the past few months. > > > Here's my question: in the XV144 and XV222 sections of the assembly manual, Q1 is installed with long leads, standing above the board.

It is a better thing to have a roofing filter, i wouldnt like to use only the dsp with the 2700 ssb filter. I have the 500hz 5 pole filter (and the 200hz 6 pole), but I find that sometime I have a nicer audio tone with a wider filtering. 1000hz is too wide for me, sure it is good with rtty, but for cw with our noisy and crowded band is too much. So I think that a 700 hz Bessel filter, or a better (wide at the base) gaussian 600hz sure would have a better audio cw in reception. -- 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 donovanf at starpower.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ky5g at montac.com From mtkoszew at gmail.com Sun Dec 23 15:58:05 2018 From: mtkoszew at gmail.com (N1VH) Date: Sun, 23 Dec 2018 13:58:05 -0700 (MST) Subject: [Elecraft] K3S - Win 10 Pro USB Audio Codec Issue In-Reply-To: <1576bce1-faff-afe1-a369-c0c82467124c@embarqmail.com> References: <1545513288406-0.post@n2.nabble.com> <1576bce1-faff-afe1-a369-c0c82467124c@embarqmail.com> Message-ID: <1545598685167-0.post@n2.nabble.com> Thanks to everyone for your suggestions, I tried them all. After additional sluething, I believe our K3S has an issue with the KIO3B board. The USB Audio CODEC will not load or be recognized on any computer (CAT control works fine and is recognized in the Elecraft K3 utility). Additional testing: I tested other devices on our club PC. It quickly recognized the USB Audio CODEC for an IC7300 and mini external sound card. I then tried my personal K3S....and it quickly recognized both the USB VCP and the Audio CODEC. Next I attached the club K3S to my personal PC - same result as with the club PC, it was not recognized on my computer either. I then tried reloading the firmware (again). No change. My conclusion is that there is an issue with our club K3S. I will have to call Elecraft support to see if there is a way to address the USB audio CODEC or if the KIO3B must be replaced. -- Sent from: http://elecraft.365791.n2.nabble.com/ From donwilh at embarqmail.com Sun Dec 23 16:07:21 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 23 Dec 2018 16:07:21 -0500 Subject: [Elecraft] K3S - Win 10 Pro USB Audio Codec Issue In-Reply-To: <1545598685167-0.post@n2.nabble.com> References: <1545513288406-0.post@n2.nabble.com> <1576bce1-faff-afe1-a369-c0c82467124c@embarqmail.com> <1545598685167-0.post@n2.nabble.com> Message-ID: You might want to wait until after New Year's day to make that call.

If Elecraft has determined that it isn?t economical for them to continue to produce the EC2, then perhaps we shouldn?t be giving side eye about what it costs to laser cut a piece of metal at even a mom and pot shop. Sure .. maybe that?s cheap, but there?s a good deal more that goes into producing an actual market-ready finished product. I could list quite a few additional steps besides metal cutting ? but that wouldn?t prove much. Any more that arguing that laser cutting metal is cheap ? unless you?d like to have raw laser cut metal as a cabinet for a radio ?

I have operated nearly 100 % CW for 64 years, and am glad I got this filter. Through the years I have found that something like approximately a 700 Hz filter is very helpful in scanning the bands and for casual QSO?s. However if you are on a budget something like a 1000 Hz or even one of the SSB filters will give your nearly identical performance since the Elecraft DSP filtering is so good. I cut my CW teeth in the old days with wide bandpass receivers and we used our brain filters quite effectively so enjoy a somewhat wider filter so we will be aware of things happening near our operating frequency. Now for sure in contest operating I do often need or want to switch in my 400 Hz filter often. I do agree with IK4EWX that CW sounds SLIGHTLY better (to my ears) with crystal filtering than using mostly DSP filtering, however the difference is small in most situations. So if you are a serious CW operator and have the extra funds you may appreciate the 700 Hz filter, however something like the 500 Hz filter or a wider filter with DSP should be satisfactory for many folks.

There should be no issues with the IC-7600 or the 7300. You will need to connect the RF keying line from the amp to the radio. Check the manual on each for the correct TX output. It is pretty straightforward as all the radio does is to pull a line to ground to put the amp into TX. The Amp will then bandsert in milliseconds. I have not used the tuner, but others will comment. I suspect it either has a amp keying line or auto sense keying. Mike va3mw On Mon, Dec 24, 2018 at 8:27 AM Tom KG3V wrote: > Are schematics available for current Elecraft products?

That is not what I did when using a TS-590 with KPA500 and KAT500. I connected the TS-590 keying output to the KAT500 and then the KAT500 keying line to the KPA500. This routing of the keying line is required since the KAT500 must be able to interrupt amp keying when changing its configuration or when high reflected power is detected. My key line routing is actually a bit more complicated than that. My path is TS-590 > SteppIR interface > LP-100A > KAT500 > KPA500. They all have to agree it's ok to QRO before my KPA500 is keyed.

If you have the PTT-KEY menu set to anything other than Off - Off, that can occur as the computer tests the com ports. Other than that, the K3S is detecting a key, paddle, or PTT closure when it is powered up. You just have to find out which one. Unplug all of them and plug them in one at a time (powering on after each one is plugged) to reveal which one is causing the error.

Much of the rolloff depends on your microphone. Jim Brown K9YC has long advocated reducing the TX EQ below 500 Hz or so in order to increase your effective communications power. An improvement of 3 dB or more can be had by reducing the low frequency audio since those low frequencies take a lot of the total power and add little to communications effectiveness. 73 and Merry Christmas, Don W3FPR On 12/25/2018 11:03 AM, Michael Blake via Elecraft wrote: > When using the stock K3s 2.7 KHz. roofing filter and all TX EQ settings are zero (0) what is the normal TX audio rolloff below 300Hz.?

The published curves ( https://elecraft.com/pages/k3s-8-215-mhz-first-if-crystal-filter-response-curves ) suggest that there will be significant low end rolloff below 300 Hz. But I have not taken the time or effort to attempt to measure it myself. I believe that the ESSB improvements also require a wider filter to be totally effective. The reason I ask is that when on-the-air testing of my new HyperX Cloud Pro headset there was not much change (none actually) noticed when I rolled 50Hz. And 100Hz. off to -16. I thought that I had seen actually measurements of the actual rolloff in the past and thought that someone might recall where there were.

What you add to the high frequency end is subtracted from the low end. The high end is normally about 3kHz which means the low end of the roofing filter is at about 300Hz. Yes, ESSB operation would require the 6kHz roofing filter. 73, Don W3FPR On 12/25/2018 12:05 PM, W2xj wrote: > The rule for a balanced sound is that the product of the lowest and highest frequency should be between 450,000 and 500,000.

The published curves ( https://elecraft.com/pages/k3s-8-215-mhz-first-if-crystal-filter-response-curves ) suggest > that there will be significant low end rolloff below 300 Hz. The actual low end is controlled by two parameters: the low cut frequency in the DSP algorithm and the local oscillator frequency (where the IF filter is placed relative to the carrier frequency). In general, the "normal" passband for a 2.7 KHz SSB signal would be 300 - 3000 Hz. In the K3/K3s that bandpass would primarily be set by the DSP. In fact, if you look closely at the response of both the 2700 and 2800 Hz filters you will notice they are not symmetrical - they have steeper skirts on the high frequency side than the low frequency side. If the filter were the only determinant of transmit audio response, one sideband would have less low end response than the other. In analog filter SSB designs, one typically set the carrier at -40 dB on the filter skirt (to improve carrier suppression) and accepted the low frequency roll off that started between 200 and 500 Hz (depending on the filter skirts). For the K3/K3S, I'm certain that Elecraft adjust the "carrier offset" to some degree for normal SSB and ESSB settings but I don't recall ever seeing response specifications other than total bandwidth (2.7, 3.0., 3.1, 3.2, 3.2, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9 and 4.0 KHz). 73, ...

An improvement of 3 dB or more can be had by reducing the low frequency audio since those low frequencies take a lot of the total power and add little to communications effectiveness. >> >> 73 and Merry Christmas, >> Don W3FPR >> >> On 12/25/2018 11:03 AM, Michael Blake via Elecraft wrote: >>> When using the stock K3s 2.7 KHz. roofing filter and all TX EQ settings are zero (0) what is the normal TX audio rolloff below 300Hz.? > From jhfitzpa at wisc.edu Tue Dec 25 16:19:55 2018 From: jhfitzpa at wisc.edu (JAMES H FITZPATRICK) Date: Tue, 25 Dec 2018 21:19:55 +0000 Subject: [Elecraft] Original Bandmaster and K3 Message-ID: <55e46c59-4004-fb54-7159-eb3c894284ca@wisc.edu> I have recently come into possession of an Array Solutions Bandmaster, the *original* edition.

A data mode software that I am familiar with have provision for PTT via CAT command and I think that is the cleanest solution. It sounds a bit like the RTS signal is 'stuck on' at the output of the internal USB to RS-232 adapter chip in your K3S. Consult with the Elecraft support and tech folks after the 1st of the year.

If you were able to test all cells and they are all the same, the pack is bad. If only one cell, you either need to dispose properly and buy a new one, or if you can find a vendor who will remove and reconnect a good cell. That is the way to go. BatteryPlus cannot do locally, I tried with another battery situation. If you run a LiPo pack down too low, kiss it goodbye. Great way for the sales team to make $'s. My advice: Use the correct charger, don't run the pack too low and recharge as required. If you try to extend operation on LiPo's you are going to damage the battery or the pack. I do RC... know the drill. I never ever ask more of the battery to avoid my high power packs to go below specs. Matter of fact, I am very conservative. When you have 2 packs at over $100 a piece, that is stupid. I monitor, check and recharge, even before necessary. 73, Bill K9YEQ https://wrj-tech.com/ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Robin Kiszka Sent: Thursday, December 27, 2018 3:40 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KX3 battery problems Hi, Some time ago I purchased a KX3.

While they are good, they do have a lifetime that is expressed in number of recharge cycles. Personal experience has shown that the life of such batteries is in the vicinity of 3 to 4 years. It is often that the no-load voltage of a battery is OK, but as soon as you draw any current, it goes "belly up". You can monitor the voltage of the pack with the KX3 alternate VFO B display.

I'll keep track of how long I have 'em in the radio and replace 'em around 3 years. But I use a Talentcell LiPo pack that gives 5, 9, and 12v. It's lightweight, comes with a charger, and was intended to charge items that take more power than a phone. It gives 6A at 12v with 8300 mAh. I keep it external to the radio of course. I use a smaller one (12v at 3A)for my old K2 since the old SLA battery died. I'm tempted to get their top-level 12v/11000mAh/6A pack for some longer endurance. The 8300mAh and 11000mAh packs also have 5v USB and 9v coaxial plugs, while the 6000mAh is only 12v/3A coaxial. The prices are all very reasonable, and the packs are compact and have tough plastic cases with power switches and LED indicators. With a Y-cable, I can plug in both the KX3 and the PX3, AND have the charger plugged in to keep the battery topped off if the drain isn't too severe. The switching wall wart chargers are even fairly quiet RF wise, as far as I've been able to tell. I DO have the NiMH pack for the KX3, and a couple of sets of Eneloops for it, but I keep them charged up for emergencies. 6000mAh Talentcell for K2: https://www.amazon.com/gp/product/B00MF70BPU/ -- $30 8300mAh Talentcell for KX3/PX3: https://www.amazon.com/gp/product/B01337QXMA/ -- $50 11000mAh Talentcell: https://www.amazon.com/dp/B016BJCRUO/ -- $65 On Thu, Dec 27, 2018 at 8:32 PM wrote: > I am finding the same with my Eneloop NiMH batteries.

I believe the 'keyword' may be "Send" or Keyout or something of that nature (PTT should be an input to the transceiver, not an output, but some manufacturers mix them up causing confusion - check the documentation). Connect that output from your transceiver first to the KAT500 AMP KEY connector and from the other KAT500 AMP KEY connector to the KPA500. That allows the KAT500 to disable the amplifier keying if the KAT500 needs to tune. You should then be "good to go" with the basic cabling. When you get the proper cable, it will integrate better with your Icom, but the basic cabling will get you on the air with your new toys. 73, Don W3FPR On 12/27/2018 11:14 PM, Ken B via Elecraft wrote: > Just received my the kap500 and found out it was missing the accessory cable which goes from the icom 7600 to the kat500.

The QSK Delay adjust the trailing hold time for the Keyout after keyup, not the start delay.

The best way to test them is to use an external battery charger built for RC that accomodates NiMH chemistry, and can both charge and discharge multiple cycles, and has a top-off low current cycle built in. This will balance the pack. Take the batts out of the kx3, put them in an empty battery holder, and run them through three charge/discharge cycles. The charger will show their true capacity. Running several cycles will build up their capacity a bit. I use only Eneloops. Regular NiMH batts can lose all their capacity in a few days, and if you let them sit too long, they are ruined. Eneloops can hold 80% of their capacity for many months. > All batteries have a finite life. > I am sure others will disagree. This is my (considerable) experience with NiMH.

I am not sure about the partial discharges, and whether each one counts as a whole cycle. That is certainly NOT true of lead-acid and Li-Ion batteries, which will survive many more partial discharges than deep ones. Li-Ion batteries should not be stored for long periods fully charged, but at 50-70 percent. Fortunately, their self-discharge rate is so low that you would have to store them for years before you would have to worry about them becoming completely discharged, which is bad for all types. 73, Scott K9MA On 12/28/2018 10:41, Bob McGraw K4TAX wrote: > Something I learned from one of our "tech reps" regarding rechargeable > batteries and charge cycles. ??

Normal NiMH batteries will self-discharge in a fairly short period. Low-self-discharge batteries will hold a charge for a long time, and can be sold as "pre-charged" so the consumer can buy the rechargeable batteries they want and not have to buy "temporary" alkalines. Eneloops are considered to be the best, certainly the most well known. 73 -- Lynn On 12/28/2018 8:21 AM, Robin Kiszka wrote: > Put in a new set of NiMh cells and all seems OK.

Consulting the factory, they stressed that the batteries were getting cycled each day that the Sun came out and the charger started charging the batteries. I used the batteries sparingly at my remote ham shack, discharging about 10 to 12 % typically on the days that I used them. Only once did I discharge them to almost 75% of full.? I should have used them more so I would not feel so cheated having them die so quickly.? My solution is to replace them with LiFePO4 batteries and disconnect them from the solar charger unless I need the batteries for a specific event.? They can go a few months with no charging.? I can keep the charge cycles at a much lower rate with LiFePO4. You can't do that with lead acid, or at least not as well.

However, use of these signals may also allow the PC?s USB port initialization to unexpectedly activate transmit at the K3S. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on. Applications that use PTT- KEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S. I have my K3s in USB.SAFE John N1JM -- Sent from: http://elecraft.365791.n2.nabble.com/ From kc4atu at hotmail.com Sat Dec 29 16:54:10 2018 From: kc4atu at hotmail.com (Bill Rowlett) Date: Sat, 29 Dec 2018 21:54:10 +0000 Subject: [Elecraft] Ideas for an FT8 Radio In-Reply-To: <1768811326.10637320.1546118162298@mail.yahoo.com> References: <1768811326.10637320.1546118162298.ref@mail.yahoo.com> <1768811326.10637320.1546118162298@mail.yahoo.com> Message-ID: 25 watts out max.

"Message board"?? Do you really want to go back to the 1980s BBS days?

Six years on a pair of big AGMs? You are lucky - I usually get about 4-5 years on a pair in float service.

My email is sorted automatically when it is received (I use Thunderbird although other email clients have similar capability). I put it into separate folders with the filters based on something in the subject line. For instance, I use a filter to place all email containing [Elecraft] into my Elecraft folder - that gets it out of my Inbox and into a folder that could be considered as my own "Elecraft Digest". I can then read the posts one at a time and delete those not of interest, reply to those I want to comment on, or save for future reference. Then I can do a SEARCH if I want to see posts referencing a particular topic (or individual). It gives me a lot of flexibility. Once a year or so, I trim off all posts older than a year old so the folder does not get too big. I figure if I have not needed anything in over a year, I can delete it. The filtering and searching tools provided by modern email clients give one a lot of capability. It takes a bit of thought to set it up, but makes email quite sane and manageable once set up for your needs and desires. Down with the bulletin boards, I can't find anything of value in those! Nabble is almost as bad, and I don't use it unless I get a link of interest, but even then I usually don't find anything valuable there. 73, Don W3FPR On 12/29/2018 7:05 PM, Phil Kane wrote: > On 12/29/2018 12:14 PM, W2xj wrote: > >> It is just that too many do not seem to have fully grasped email after about 3 plus decades. > > When one cuts one's teeth on torn-tape Telex/Teleprinter systems of the > 1950s/60s, e-mail is the greatest thing since sliced bread.!

Yes, Thunderbird can do a great job, but it won't filter off topic, and you have to do a lot of work. With POPfile, you classify a few messages (KX3, K3S, Antenna, Digital Modes, whatever) and the filter "scores" the words from the messages you classified, and uses the score to put the message where it belongs. If it gets one wrong, you reclassify it, and the filter improves. It does *not* rely on posters to put rational subjects, and it deals with topic drift automatically. POPfile works with real mail clients (with their awesome search capability). 73 -- Lynn On 12/29/2018 4:49 PM, Don Wilhelm wrote: > The filtering and searching tools provided by modern email clients give > one a lot of capability.?

I believe the 'keyword' may be "Send" or Keyout or something of that nature (PTT should be an input to the transceiver, not an output, but some manufacturers mix them up causing confusion - check the documentation). Connect that output from your transceiver first to the KAT500 AMP KEY connector and from the other KAT500 AMP KEY connector to the KPA500. That allows the KAT500 to disable the amplifier keying if the KAT500 needs to tune. You should then be "good to go" with the basic cabling.? When you get the proper cable, it will integrate better with your Icom, but the basic cabling will get you on the air with your new toys. 73, Don W3FPR On 12/27/2018 11:14 PM, Ken B via Elecraft wrote: > Just received my the kap500 and found out it was missing the accessory cable which goes from the icom 7600 to the kat500.

Passwords have become unworkable as a security measure. Too many sites need them, and some of those will get compromised,leaking your password; Using a different one for each site means it is difficult to remember them all; Rules that you must not write them down result in the same password being used across both well secured and poorly secured servers. Rules that passwords be changed frequently, combined with the need to have many different passwords, results in weak passwords, as inventing good ones, that are different form other people's, is difficult. Any organisation where security is important should not be relying solely on passwords. On the original subject, most technical mailing lists obey the convention that mail to -owner@ will go to a human administrator (I would say that any well managed list should do this). Failing that, many will forward anything not understood to a human (or reply with help saying how to contact a human) if mail is sent to -request@ and doesn't contain a valid list command. Most such lists also have a number of guidance links in the message headers, e.g., for this list: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Amongst other things, the help reply says you can send this to the -request address: unsubscribe [password] [address=
] Unsubscribe from the mailing list. If given, your password must match your current password. If omitted, a confirmation email will be sent to the unsubscribing address. If you wish to unsubscribe an address other than the address you sent this request from, you may specify `address=
' (no brackets around the email address, and no quotes!) This does rely on the subscribing address being still valid, but if it is not, the mail bounces should eventually get the subscription terminated, automatically.

I think that would be a "killer" for data modes like FT8 which need rather precise timing. To get an idea about the latency of Bluetooth, try monitoring your CW with a Bluetooth headset - unless you are a slow operator, the delay (which is caused by latency) will drive you to phone operation. 73, Don W3FPR On 12/30/2018 2:26 PM, Jeff Stai wrote: > Hmmm... as long as you use a generic tablet with a KX2, you're going to > have a box and wires.

Secondly, it will compute the SWR and if it is below 1.5, it will go into bypass - no tuning is necessary. Is it possible that either one of those conditions exist? 73, Don W3FPR On 12/30/2018 6:12 AM, Ken B wrote: > Yes? from the 7600 accessory 1 pin 3 to the kat500 > > Sent from Yahoo Mail on Android > > >? ?

That connection list will be most helpful in this effort. My thinking on the ground issue is that the power-plug ground is completing a circuit that should not exist and thus disrupting operations on band change. The question would be what is connected to ground that should not be, and where? Are the KPA and KATs kits or did they come assembled? 73!

The encoder itself seems fine, when I rotate it, it performs perfectly. When I push on it, often the marker does not move or, it moves the frequency part way. If I hold the knob and apply a little downward pressure when pushing it usually works. This leads me to think the switch has an issue. Because this happens often but not continuously, I don't think it has anything to do with the logic circuitry and the downward pressure usually does the trick. It seems mechanical in origin. I thought I might spray Deoxit to help with the contact if build-up on it is the issue but I don't know how that might affect the encoder function. I should open the case and assure the solder connections are intact. Before contacting Elecraft for a new encoder, has anyone had this issue and resolved it?

Thanks for the detail. Table 2 on page 8 of the KAT500 manual should have given you the exact connections you needed to make for the Molex to KAT500 cable. Note that the plug o the KAt500 end is stereo with tip, ring and sleeve. Please recheck these connections to make sure that pin 4 of the Molex does indeed go to the sleeve of the mini-phone plug. It would be best to ohm out the cable to make sure the signals go to the right places and there are no shorts between pins. Table 3 on that same page shows the Key-line connections, which I suspect are correct at the point. In any case be sure to check that cable as well. 73!

Thanks for the detail. Table 2 on page 8 of the KAT500 manual should have given you the exact connections you needed to make for the Molex to KAT500 cable. Note that the plug o the KAt500 end is stereo with tip, ring and sleeve. Please recheck these connections to make sure that pin 4 of the Molex does indeed go to the sleeve of the mini-phone plug. It would be best to ohm out the cable to make sure the signals go to the right places and there are no shorts between pins. Table 3 on that same page shows the Key-line connections, which I suspect are correct at the point.

My thinking on the ground issue is that the power-plug ground is completing a circuit that should not exist and thus disruptingoperations on band change.

Unplug the mini-phone plug from the KAT500. This will leave the KAT powered from the 7600, but requesting a tune from the 7600 won?t cause the KAT to respond. Next key the radio and make sure everything works properly. After that, change bands on the radio and re-key. Both the Kat and KPA will sense the new band and both should change. The KAT will further require a tune and should break the key line causing the KPA to drop out of transmit. Try this test and let me know what happens. Oh, and before I forget, there is actually no soldering involved in assembling either the KPA500 or the KAT500. They are both no-solder kits. But there are a lot of mechanical tasks such as screwing in small screws and tightening nuts. Having just assembled one of each of these, I can?t say I blame you for buying it factory-built. 73!

I do agree with Jack the issue seems to be related to a grounding issue.? And I agree with Jim as his assessment likewise.?? His work and that of W. Silver from ARRL does support this thinking.?? [The ARRL publication Grounding and Bonding for The Radio Amateur is a MUST HAVE for every station.] Three points: (a) each piece of equipment should be connected to the station supply via a dedicated ground/bond conductor. (b) the 12 ft driven ground with 0 ohms resistance is questionable.? And if this ground rod is not bonded back to the AC Mains ground outside of the house, this must be corrected as it presents a dangerous condition and clearly is not in compliance with NEC. (c) the power strip being used for the station equipment,? from my experience, is usually questionable in terms of integrity. I would disconnect any station ground to the outside. ? Anyway, any and all of the lightning protection devices should be applied to each feed line and rotor line outside of the structure and connected to the driven ground. ? Again, this ground must be bonded back to the AC mains ground. I would connect each piece of equipment with a dedicated ground/bond conductor to the station power supply ground terminal.?? For this I use #10 AWG auto primary wire with a suitable ring terminal which is crimped and soldered on each end.?? As to the power supply ground point, do note that the DC negative may or may not be connected to power supply ground. For station AC power distribution, lacking dedicated wall outlets, I make quad boxes using good quality duplex outlets and caps {plugs} and do not use the "stab" type connection.? Hook the wire around the screw clockwise and tighten the screw.? Use #12-3 rubber covered,{ SJ as I recall} for the pigtail. I would then re-evaluate the condition of concern. 73 Bob, K4TAX On 12/30/2018 8:30 PM, Ken B via Elecraft wrote: > Thank you - I followed Fig 3 on page 10 which is specific to ICOM.

Unplug the mini-phone plug from the KAT500. This will leave the KAT powered from the 7600, but requesting a tune from the 7600 won?t cause the KAT to respond. Next key the radio and make sure everything works properly. After that, change bands on the radio and re-key. Both the Kat and KPA will sense the new band and both should change. The KAT will further require a tune and should break the key line causing the KPA to drop out of transmit.? Try this test and let me know what happens. Oh, and before I forget, there is actually no soldering involved in assembling either the KPA500 or the KAT500. They are both no-solder kits. But there are a lot of mechanical tasks such as screwing in small screws and tightening nuts. Having just assembled one of each of these, I can?t say I blame you for buying it factory-built. 73!Jack, W6FB On Dec 30, 2018, at 6:30 PM, Ken B wrote: Thank you - I followed Fig 3 on page 10 which is specific to ICOM.

Thanks for the detail. Table 2 on page 8 of the KAT500 manual should have given you the exact connections you needed to make for the Molex to KAT500 cable. Note that the plug o the KAt500 end is stereo with tip, ring and sleeve. Please recheck these connections to make sure that pin 4 of the Molex does indeed go to the sleeve of the mini-phone plug. It would be best to ohm out the cable to make sure the signals go to the right places and there are no shorts between pins. Table 3 on that same page shows the Key-line connections, which I suspect are correct at the point. In any case be sure to check that cable as well. 73!Jack, W6FB On Dec 30, 2018, at 4:13 PM, Ken B wrote: Good evening??The Icom IC-7600 KAT500, and KPA500 are each?grounded to a single terminal strip with a #10 cable directly to a ground rod 15 ft away.

My thinking on the ground issue is that the power-plug ground is completing a circuit that should not exist and thus disruptingoperations on band change. The question would be what is connected to ground that should not be, and where?Are the KPA and KATs kits or did they come assembled? 73!Jack, W6FB On Dec 30, 2018, at 2:22 PM, Ken B wrote: Please allow me to clairify.? ?Everyone deserves time off.?

If you don't have one, you should purchase one right away. I have seen the type of fault many times, and a good percentage of the it is not the amp.? One fault I have seen more than once is using high power into a load with high SWR.? That develops very high voltages on the coax, and it arcs through.? Once that happens, you need to find the issue with the antenna and replace the coax.
