It isn't listed in the specifications. I don't know, but I'm using an ARR GasFET preamp at the RXIN/OUT patch point, and the ARR 0.5 NF seems to be slightly better than the K3S-series Transverter Interface. Although I own an ARR mast-mount version, I'm afraid to put it at the tower because the 6M antenna is only about 10 ft below the SteppIR that I drive legal limit. :) The loss in my 325 ft of 7/8-in hard line plus coax for rotator loop and jumper at the shack is is a bit less than 1 dB on 6M. 73, Jim K9YC From w1sfr.qrp at gmail.com Wed Jul 1 07:34:15 2020 From: w1sfr.qrp at gmail.com (Stephen Roberts) Date: Wed, 1 Jul 2020 07:34:15 -0400 Subject: [Elecraft] Weird sounds coming from my K1...need a qualified exorcist Message-ID: Sorry.

Connect a dummy load to the base K2 BNC ANT jack. After that, check the maximum power from the base K2 - you should have at least 10 watts on each band. Record the power for each band.? To be clear, are you saying to disconnect all 3 connections between the K2 and the KPA-100? If there is 10+ watts out on each band, do I need to realign the band pass filters?

Everyone else is reduced to guessing because they don't have access to your PSU/K2/power lead. Simple: Measure the PSU voltage on RX at the PUS terminals. Measure the PSU voltage on TX set to 100W at the PSU terminals. Compare both of these with the internal K2 voltage display. Report the findings.

When the band is open, either via E or F2 propagation, signals are usually very "loud". The only "weak" signals are those at the initial start and end of the opening. I remember working a station in Alaska from here in Virginia on SSB, who was running 10 watts to a balcony mounted Saturn-6 halo, barely 10 feet off the ground ! He was +10 dB over S nine for over an hour. SO, don't fret over whether your noise figure is 0.5 dB or 2.5 dB, any decent modern radio will hear just fine. 73, Charlie k3ICH >160 countries confirmed on 6M on SSB & CW ONLY, no PSK-31, FT-8' etc. From ab2tc at arrl.net Wed Jul 1 11:48:56 2020 From: ab2tc at arrl.net (ab2tc) Date: Wed, 1 Jul 2020 08:48:56 -0700 (MST) Subject: [Elecraft] K3s noise figure spec In-Reply-To: References: Message-ID: <1593618536791-0.post@n2.nabble.com> Hi, Here is a quote of my response to the exact same question in 2017: "Hi, According to the ARRL review in November, 2dB!

That particular one cannot be bent over because it will interfere with the PA transistor mounting. If you also ordered the KSB2 option, there is an extra 0.01uF (10nF) capacitor in that kit. It has a narrow lead spacing, but can be used to solve this problem. If no KSB2, then do you have a capacitor that you can use instead of the one supplied. 73, Don W3FPR On 7/1/2020 5:19 PM, carlos.p wrote: > hi, c 135 10nf cap fitted on the bottom side of the rf board, > between the 2d fastener and transistor > seems sticking out to high, i wonder if someone experienced this, > not soldered in yet, i wait for some possible comments on that, > regards carlos on6cn > From norrislawfirm2 at gmail.com Wed Jul 1 17:39:58 2020 From: norrislawfirm2 at gmail.com (Eric Norris) Date: Wed, 1 Jul 2020 14:39:58 -0700 Subject: [Elecraft] OT: IC-705 Message-ID: I know Elecraft is very busy finalizing the K4, but I wonder if they have a secret Tiger Team working on a response to the IC--705?

The air cooled dummy loads not only require power for the fan, but may be over-rated for their power spec. I prefer dry or oil immersed dummy loads. A good dummy load should present a 1.0 SWR for all the bands of interest. Check with an antenna analyzer. If you have access to a vector analyzer, it should show 50 ohms resistive and zero reactance at all frequencies of interest. Those home-built with resistors can usually be OK up through 30 MHz, but may fail at 50 MHz and above - and that includes the 'cantenna' types (oil immersed resistors). careful construction is required to reduce the inductance involved in the mounting and assembly. I have 3 'cantenna' type dummy loads, two for 150 watts In quart cans and one for 1000 watts in a gallon can. They are OK up through 30 MHz, but not above that level. They are good for loads on the transmitter, but are not sufficient for precise measurement. I also have 2 precision dummy loads that are good up into the GHz region. Those are the ones that I use for measurements (up to 100 watts) And for the K3 TX Gain calibration. I have another that I rate at 50 watts (using a 100 watt Caddock thick film resistor on a heatsink) that is a good load up through 220 MHz. None of mine are air cooled. 73, Don W3FPR On 7/1/2020 7:45 PM, Eric Norris wrote: > Basically the same thing.

That particular one cannot be bent over because it will interfere with the PA transistor mounting. If you also ordered the KSB2 option, there is an extra 0.01uF (10nF) capacitor in that kit. It has a narrow lead spacing, but can be used to solve this problem. If no KSB2, then do you have a capacitor that you can use instead of the one supplied. 73, Don W3FPR On 7/1/2020 5:19 PM, carlos.p wrote: > hi, c 135 10nf cap fitted on the bottom side of the rf board, > between the 2d fastener and transistor > seems sticking out to high, i wonder if someone experienced this, > not soldered in yet, i wait for some possible comments on that, > regards carlos on6cn > From gibson at alma.edu Thu Jul 2 09:29:31 2020 From: gibson at alma.edu (John Gibson) Date: Thu, 2 Jul 2020 13:29:31 +0000 Subject: [Elecraft] Test message - 2020-07-02 Message-ID: Test. 73, John, no8v From jaunti at gmail.com Thu Jul 2 09:36:47 2020 From: jaunti at gmail.com (Jan Timmers) Date: Thu, 2 Jul 2020 06:36:47 -0700 Subject: [Elecraft] OT: Other Radios In-Reply-To: References: Message-ID: Regards; John Timmers Hehe - lightly salted snow.

Looking at the rating curve in the manual, that is 300 W for 30 seconds or 100 W for 90 seconds. For $50, I?d still go with the Oak Hills Research kit. That handles 100 W continuous, no time limit. http://www.ohr.com/rfl100.htm wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) From n7tb at comcast.net Thu Jul 2 12:54:02 2020 From: n7tb at comcast.net (Terry Brown) Date: Thu, 2 Jul 2020 09:54:02 -0700 Subject: [Elecraft] OT: RF Choke question Message-ID: <004501d65091$66ce3b80$346ab280$@comcast.net> I need some advice from someone with experience in dealing with RF problems. I have an in-home elevator that is putting out RF hash in harmonic locations on the ham bands, especially 80 meters. I've gotten tired of dealing with the noise. I have both a 240V circuit and a 120V circuit feeding the control panel. The 120V circuit powers the cab lights and elevator switches. The 240 feeds the motors the raise and lower the elevator. The cab is 3 ft. by 4 ft. so it isn't a small residential elevator. We had our house designed for it when we built two years ago. I have two 4 in. inside diameter RF toroid chokes that I bought specifically for the ham bands. I plan on putting these RF chokes on the electrical supply lines for each circuit right before they enter the control panel to see if it helps my RF issue. I have two questions. 1. Is rapping 10 turns of the electrical wires of each circuit around the toroid enough? 2. The electrical wires are individually connected to the control panel. In the case of the 120V, there is a white, black, and ground. In the case of the 240, there is 3 reds, a black and a ground. Do I have to wrap the ground wires of these circuits around the toroid as I do the other electrical wires? It will be interesting to see how much better my K4 will be when I get it, in rejecting RF noise, compared to my KX2, KX3, and K2.

Chokes must be right at the noise source (the elevator motor's variable speed control electronics), NOT near the panel. Choke both the AC line side and the wiring between the motor's controller and the motor. Also, make sure that the green wire between the AC line and the motor is the only ground for the elevator. If possible, make all wiring associated with the elevator twisted triplet (for 120V or pure 240V) and twisted 4-conductor for combined 120/240V wiring. 73, Jim K9YC From k6dgw at foothill.net Thu Jul 2 15:17:08 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 2 Jul 2020 12:17:08 -0700 Subject: [Elecraft] OT: Other Radios In-Reply-To: References: Message-ID: <823ea6e9-85bb-d04d-d63a-389cb68c1f5c@foothill.net> Can't report on snow, seasoned or otherwise, but never underestimate the usefulness of a barbed wire fence.?

NR6TT's Field Day was a Failed Day this year. Wanna know what it's like to break your slingshot on the very first attempt to use it? Good thing my 14-year-old was there to throw a few fastballs 20 feet up into the trees. And then this: Isn't FlexWeave wire supposed to be the Next Big Thing? As soon as I started to tension one end of the doublet, it broke. Man, it twanged! And not at a soldered joint or wrapped point... but right in the middle of the span! I was incredulous. Luckily, I brought a butane soldering iron, which barely worked at the 3000 foot elevation near Lassen Peak. Somehow I managed to repair the break, and spent more time in 100 degree heat putting up the antenna again, then thinking I could outsmart Murphy (!) I tried tensioning the *other* end of the antenna. And it snapped again-- in a different spot!! Yes, this was the 3rd Field Day I put up the same antenna, but what the heck? Is Flexweave that easily snapped? I'm not impressed. Well, as you know, when your antenna breaks, your Field Day is pretty much ended. I guess we could have used a piece of the broken Flexweave as a random wire, but my heart wasn't into it, for a number of reasons. (We had planned on operating on 40 meters only.) Instead, we went swimming in Hat Creek, had a great salami sandwich dinner and read stories to each other until we fell asleep. So it wasn't a total loss. Total score: 0.? Time spent with Blaise: Priceless. Al?

New amps have the mod already done. I modified my amp s/n 423 by changing two surface mount chip resistors on the filter board in the amp. Not for the faint of heart. One of the chip resistors is the size of "16" in the date 2016 on a penny. TINY!!! On older non-modified amps Pure Signal will only work at higher power since the level out the sample port is too low. It will work in the 1000 to 1500 watt range but not down to 20 watts like it does after the mod. Current production amps have this mod done along with several other mods that were incorporated after my amp was purchased. I HIGHLY recommend this mod be done by Elecraft unless you absolutely have the experience and equipment to do surface mount rework properly. Last thing you want is a $6000 paper weight I do not know when this mod was put into production amps. My Pure Signal has performed from 20 to 1500 watts output withy an Anan 7000dle (blue face) without any attenuation added. I have since sold the Anan but keeping the KPA1500 as it works VERY well. Solid and dependable after several mods were done to bring it up to current production standards. If you think I am kidding about the size of the chip resistor I can send a picture to anyone interested. I did take a picture next to a 2016 penny for reference ? -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of charles at k5ua.com Sent: Thursday, July 2, 2020 4:12 PM To: Elecraft at mailman.qth.net Subject: [Elecraft] KPA-1500 Pure Signal Output Does anyone know if the RF coupler output in the KPA-1500 is functional yet?

I think if you live in an area where there is high populations of amateurs such as FN20 or NW Europe it does help enormously if you can hear the DX early in the opening before the pileup really gets going. However for most urban or semi urban operators 6m is a noisy band. You only need enough gain to raise your noise floor by 10-15dB when a resonant antenna is connected. Any more than that and you have too much gain and you will be hit very hard by the HUGE signals that are around during a typical 6m opening. This is especially important now that we are all on 50.313/50.323. I must admit that I use an external preamp with my K3S so that I can use a band pass filter and a 2 way splitter (SDR for 50.323). I have 25dB gain and a 0.5dB NF LNA, the whole chain is- 0.5dB for the coax cable,- 1dB for the band pass filter, - 3dB for the splitter and a 6dB attenuator which I take out when on EME. My system noise figure is 2.9 dB for terrestrial and 1.6dB for EME. This is probably better than needed. The background noise on 6m dominates sensitivity. More gain than you need is counterproductive. 73 Conrad PA5Y ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of Charlie T Sent: 01 July 2020 17:26 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3s noise figure spec I can't speak for E.M.E operations, but from over 60 years of experience on 6M, I can tell you that super sensitive receiver performance is NOT a pre-requisite to working LOTS of DX of 50 MHz. When the band is open, either via E or F2 propagation, signals are usually very "loud". The only "weak" signals are those at the initial start and end of the opening. I remember working a station in Alaska from here in Virginia on SSB, who was running 10 watts to a balcony mounted Saturn-6 halo, barely 10 feet off the ground ! He was +10 dB over S nine for over an hour. SO, don't fret over whether your noise figure is 0.5 dB or 2.5 dB, any decent modern radio will hear just fine. 73, Charlie k3ICH >160 countries confirmed on 6M on SSB & CW ONLY, no PSK-31, FT-8' etc. ______________________________________________________________ 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 g0ruz at g0ruz.com From k2vco.vic at gmail.com Fri Jul 3 03:56:22 2020 From: k2vco.vic at gmail.com (Victor Rosenthal 4X6GP) Date: Fri, 3 Jul 2020 10:56:22 +0300 Subject: [Elecraft] [OT] Failed Day In-Reply-To: <137995580.1482038.1593736087978@mail.yahoo.com> References: <137995580.1482038.1593736087978.ref@mail.yahoo.com> <137995580.1482038.1593736087978@mail.yahoo.com> Message-ID: <75fa6b59-b5fc-a07f-4ee2-bd8feb4b07fc@gmail.com> I found this out the hard way at a FD site in the Sierras.

The audio world has not matched impedances since the old days of tubes. Typically a low impedance source is used to drive a high impedance op amp input. 73, Don W3FPR On 7/3/2020 9:07 AM, Rich wrote: > I am interested in using a studio mixer so I can use a single mic with > two K3s. > > The mixer output impedance is 150ohms and the K3 mic input is looking > for 600ohms. > > I have seen several articles using studio mixers with two radios but > none mention using an audio transformer to correct the miss match. > > Should I not be concerned about the difference in impedance? > > Do anyone have a recommendation on a device to match the the impedances?

Message-ID: <570ea2b9-724a-06b4-f821-799d564d8b8f@inkbox.net> Today I installed a new K144XV 2-meter module and K144RFLK reference lock board in my K3S. While trying various experiments to put it through some paces, I set the radio up with WSJT-X and configured it to listen for FT8 on 144.174 MHz, after I manually added that frequency to WSJT-X's menu. I notice that when I use the band pulldown on the WSJT-X top page to select 2m, it briefly displays 144.174 000 as the frequency, but then quickly changes to 144.173 998. The frequency on the K3S's display, however, still appears as 144.174.000. I tried this a couple of times in a row, with the same result. (Not an elbow-jog in this case.) I assume this has to do with frequency offsets. Although the written label on the K144XV case indicates that tests at Elecraft showed an offset of +3.83 (Hz, I assume) for the 144 MHz subband and +1.95 (Hz) for the 146 Mhz subband, based on the instructions for the K144RFLK board I ignored those written values. Instead, I went to Config:XVn OFS, hit 0 and noted that a REFLOCK value of -2.34 (Hz, I again assume) appears on the K3S display. This, I gather, is derived from the radio's master K3REF oscillator. So, two questions. First, does it seem likely to others (as it does to me) that the 2-Hz difference showing up in WSJT-X is caused by this -2.34 (Hz) offset? Second, is there a way to resolve this so that the frequencies shown in WSJT-X and on the K3S agree?

It had always been annoying, but after the Covid lockdown and my wife had to work from home, she was in the office/hamshack here 10+ hours a day, and leaving the KPA powered up in standby was just too loud for her to concentrate. It cost about $64 shipped to get the replacement front panel LED board, which includes a higher-value 3W resistor that reduces the idling fan noise to almost nothing now. It's a very simple mod that in retrospect I could have done myself, but for me with my shaky hands and not-great eyesight it's a big plus to have a friend like Dave who knows his stuff. If you have an older KPA1500 and the PSU fans (not the RF deck fans) were driving you nuts, this mod works great, and eliminates a big source of frustration. --------------------------------------------- 73 and Good DX Peter, W2IRT President, North Jersey DX Association DXCC Card Checker Letter O Manager, ARRL Incoming 2nd District QSL bureau From lists at subich.com Sun Jul 5 13:06:52 2020 From: lists at subich.com (Joe Subich, W4TV) Date: Sun, 5 Jul 2020 13:06:52 -0400 Subject: [Elecraft] K2 Radio interface cable to connect MFJ-993B ATU In-Reply-To: References: Message-ID: >> Best to ask MFJ how they detect TUNE mode in the K2, and once you >> have that answer, we can tell you how to construct the cable for >> both the PC and MFJ ATU connections.

So if it misses it for some reason, it won?t switch. Be sure the cable between the radio Aux port and the amp is completely seated and such. And make it a habit to watch the front panel on the K3 when you switch on the KPA or select operate. You should see the KPA500 Operate message. The other way you can check is wiggle the PWR knob and make sure the * is in the window. That tells you that the radio is using the amp power settings.

(The CW nets come during the dinner hour, and today I was at a family picnic dinner.) On 20M I could hear over half of the stations, some at ESP levels, but only Steve, WM6P managed to hear me and relayed my checkin. This was running 100W from my K3 to a 2 element wire beam. I was hearing Eric, WB9JNZ at 55 to 57, but he couldn't hear me. I've always assumed that being in Chicago, he has a fairly high local noise floor. I'm out in the country and can hear quite well. 40M was a total bust. I could barely hear anyone, and no one could hear my 100W to a dipole. The K3 and the two antennas worked well during Field Day, so I put it down to propagation. The question on 20M is why I could hear well and others couldn't hear me. It may be worthwhile to swap out the 20M antenna for another one and see if that improves things. Of course, on Field Day, I did most of my Qs on CW or digital -- two points per Q vs. one after all. And, CW and digital can punch through when conditions aren't good enough for SSB. 73 Bill AE6JV On 7/5/20 at 10:28 PM, ed at w0yk.com (Ed Muns) wrote: >Actually, the K4 I am currently using is Wayne's SN 2.

One of these years, perhaps, HF conditions will pick up to the point where my KX3 might just enable me to manage a Net check-in from this side of the Atlantic. Not yet, though. I have, on one or two occasions this year, just about almost managed to hear (maybe) the occasional SOTA activator operating from a summit on the eastern side of North America, but none yet clearly enough for me to work, though other operators in Europe (with better antennas and better Morse than me) have succeeded. > On the next call I copied M0YK M0YK M0YK.?I stared at the paper trying > to figure it out.?With code this good why hasn't he upgraded to a G > call? Heh. Given, for the most part, G* calls were issued first, and M* (and 2*) calls only came along (for amateurs, at least) when the G* space was full, I'm not sure there's ever been a path to upgrade from M to G. There are chunks of the G* space that used to be "class B licences" (without HF access), but that distinction died with the Morse Test. There have been cases where folk have taken over a call from a silent-key relative, but they're unusual. For the most part, calls are never re-isssued. Recently the regulator has relaxed (or possibly "confused") conditions a bit, and released some calls that were previously marked as "not to be isssued" into the pool, but changing your call when you're not also upgrading your licence is, at best, tedious. At best, these days, the only assumptions you can make are that Foundation licence holders will have an M?3*, M?6* or M?7* (where the ? is the regional modifier) call, Intermediate licence holders will have a 2* call, and all the rest will have Full licences of some vintage. Even then, there are some short (1- or 2-letter suffix) calls that break the pattern. https://en.wikipedia.org/wiki/Call_signs_in_the_United_Kingdom and one or two other places try to make sense of the whole muddle, but just when it seems they've nailed it some other confusion comes along... -- 73, Rick, M0LEP (KX3 #3281) From a.durbin at msn.com Mon Jul 6 09:29:05 2020 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 6 Jul 2020 13:29:05 +0000 Subject: [Elecraft] Strange Amplifier behavior Message-ID: "I have the USB communicating at 38400 Will try and back that off and see if that helps!" You seem to have confused "polling rate" with "Baud rate". Polling rate defines the interval between each frame of data requests (how frequently each request is sent). Baud defines how quickly each of those data requests is sent (the time it takes for each request to be transmitted). To reduce the K3 processor workload you would need to reduce the polling rate, not the Baud rate. I cannot comment on whether either will impact your problem.

Just super when you talk to an engineer and get advice on how to self diagnose. Back in another life I had an HP 60 KHz antenna preamp fail. Talking to an HP engineer, he suggested that he had one of those in his desk drawer and would pop it in the mail. That?s what I look for with ham radio purchases.

The first is that it produces distortion on 30 meters with side-bands that appear across the spectrum. There's no distortion on 20 or 40 meters so the condition is unique to 30 meters. The other issue is with 17 meters. I measured 8 watts output on this band (external watt-meter) but the signal does not show up anywhere on the 17 meter band. The receiver appear to be working, but it's not receiving 17 meter signals. I'm hoping these are minor issues that someone on the reflector maybe familiar with. The rig ( s/n 554 ) appears to be in excellent shape inside and out and the build quality is very good. Any help would be greatly appreciated.

This may NOT be your issue. However I have noticed SpectraVue does not operate as smoothly as it once did, as the waterfall freezes momentarily when demod frequency is changed .

In-Reply-To: References: Message-ID: I have both.? I've had the KPA500 much longer of course and it's nice.? Small, concise and quiet, perfect for closest stations (tight spaces). Having the KAT500 (essentially) built into one package with the 1500 watt amp (less cabling but one less antenna port too than the KAT500) with legal (US) limit is awesome, meaning full range from 0.1-1500 watts out (with overhead, not straining, don't ask ;-) oops). Since I moved to strictly resonant antennas, the KPA1500 tuner is being used only as an antenna switch, the fan noise isn't awful (the 12V 60A power supply fan on the other hand... wow!), but since that 240V circuit isn't on the house generator, when the power goes out, it'll be a quick swap to put the KPA500/KAT500 back into play.? It's nice to have options. With the KPA500, one must still use finesse, with the KPA1500, one shouts "Mongo hungry; feed Mongo!" (movie reference).? I strongly suspect that the KPA1500 will integrate so well into the K4 it'll simply be amazing, outstanding, (I'll find out later this summer). Each has it's place, if we ever get out of house arrest and back to having DXPeditions.?

If the LED is shorted (admittedly a less likely possibility) it won't have any (or at least very little) voltage across it ... just as if its drive circuitry was bad. Having been an engineer responsible for some LED product lines in the long distant past, I would say that the most likely faults would be an open LED (bad wire bond) or some fault in the drive circuitry, but a crystal fault could also cause a short in the LED. 73, Dave??

With your program it reads the WORKING Temp sensor in the amp and increases the speed as required automatically. With the Elecraft KPA1500 Remote software, it also reads the WORKING temp sensor, but you have to manually increase the speed as you want. STILL does not fix the issue within the amp of not automatically increasing the fan speed as the temp goes up. Thank you for your program. Great stuff.

Like many of you I worked the 13 Colonies event this last week. I have a K3, s/n in the 5600 range with the new SYNs and I'm running a KPA500 into a Carolina Windom when it isn't arcing.? I have TX EQ set up like this: ? 50 Hz = -16 dB 100 Hz = -16 dB 200 Hz =?? -3 dB 400 Hz =??? 0 dB 800 Hz = ?? 0 dB 1.6 KHz = +3 dB 2.4 KHz = +3 dB 3.0 KHz =? 0 dB Mic drive at 9, and compression is set at 20 and I use a Yamaha Shedmaster CM-500 headset.? My wife thought I had some weird disease due to all the black specs shedding from the headphone pads... I wanted to pass along to you Elecraft engineers my experience during this event.? I am a CW-only op for the most part and really never hear signal quality reports other than the obligatory 5xx. Switching reluctantly to SSB and swinging down that odd foam thing which usually resides over my head I received numerous comments like: "Best signal of the day here, very clean audio!" and "Wow! It sounds like you are in the room here, excellent audio"? and "Your signal is audible above the pileup because it is so clear!" and a few others which really surprised me.? Who knew you could actually send your voice through a ham radio! I take no credit for any of this other than turning the rig on. I heard many crappy sounding SSB signals during this event, some even difficult to understand despite good signal strength and I appreciate Elecraft making the K3 operate so well, I believe it was a real advantage.? I can only hope the K4 will build on this quality! Thanks again, guys!

I have the K3/10 and KX3 which are both 12w output and drive my KXPA100, nicely. It has the KXAT100 tuner. If I decided to have high power on HF that might also mean an upgrade in HF yagi (20-10m). I have an aged Hygain TH3mk4 which needs the antenna tuner to match. Its the old trap design so might opt for a SteppIR or a log-periodic, both of which need no tuning. 6-dBi gain would be adequate, non-contester or DXer on HF.

I have encountered it a few times in the process of repairing over 1000 K2s. The problem source is usually on the Control Board. Check the voltage on the gate of Q3 - it should be zero during receive. Also check the gate of Q4. If both gates are at about 5 volts, then you have a problem with the MCU and it should be replaced. You could try a Master Reset, but it is unlikely to correct the problem. OTOH, if only one gate Q3 or Q4 is at 5 volts, then look for something that is putting the K2 into transmit. Should you find the gate of Q3 at zero volts, and you still have 8T active all the time, either Q3 is not conducting when it should or there is a problem with Q1 and the RP1 resistors. 73, Don W3FPR On 7/11/2020 12:57 PM, Robert Calver via Elecraft wrote: > Hi Guys > > Anyone had a this fault?

Do you know that the Bird and slugs are good? Do you know that the dummy load is good? Bird meters, when they are calibrated, are specified at 5% of full scale, so +/- 1.25 W for the 25 W element and +/- 0.5W for the 10W element. Bird meters are rugged, but not really all that accurate. The dummy load should be 50 ohms resistive over the frequency range of interest. If they have been cooked, they often change. So, for two meters being off by 0.5W is within the calibration accuracy, even if the slug was calibrated. Slugs don't usually drift much though, unless cooked. Hams hardly ever calibrate their test equipment because it does cost a lot to do so, and it has to be done every year or two. In the case of the slugs, I think that calibration means measure and if bad, chuck it. The meter itself has a calibration, I believe. For 40M and 20m the readings are so different that it is likely something is wrong. Can you measure a different rig or with a different meter? 73, Mark W7MLG From ghyoungman at gmail.com Sat Jul 11 16:19:00 2020 From: ghyoungman at gmail.com (Grant Youngman) Date: Sat, 11 Jul 2020 16:19:00 -0400 Subject: [Elecraft] KX3 power out In-Reply-To: <23d1adb6-6ec5-74ee-a42c-ebc14ee90a18@inkbox.net> References: <07eb80bf-c36b-e2f8-b4f8-52144e84b09c@inkbox.net> <23d1adb6-6ec5-74ee-a42c-ebc14ee90a18@inkbox.net> Message-ID: As a start, I?d recommend running through TX GAIN calibration using the KX3 Utility ?

Good suggestion. If a 2-meter module is installed, as is the case with mine, I wonder if the automated calibration using the KX3 Utility flies through all the bands including that one? I wouldn't want to start pressing buttons and find out the wrong way. The reason for my concern is that I only have one dummy load, the MFJ-260C. I'd like to get ahold of the Oak Hills Research RFL-100 mentioned here recently, but unfortunately when I tried to order one a few days ago his website said all sales had been suspended indefinitely due to COVID. I guess I can either scrounge another dummy load, or do the calibration band-by-band manually. Re Mark's questions about the Bird 43 and slugs, I do have an older Bird that I don't trust a great deal, but this one was bought new about a year ago, and the slugs are the same vintage or newer. I can try them out with other radios. As for Walter's point about the ATU, the results are mighty odd. I just set the KX3 to 40 meters with 15 watts out, appropriate slug in the Bird 43, set ATU to bypass and started keying. The power out dropped to about 5w. I then set ATU to auto and tapped the ATU Tune button. With the radio still set to 15w out, the Bird now peaked at about 25w! Is it plausible that antenna tuning activity within the KX3 could actually increase the TPO by ~5x? Or does that cast even more suspicion on the Bird?

I'd like to get ahold of the Oak Hills Research RFL-100 mentioned here recently, but unfortunately when I tried to order one a few days ago his website said all sales had been suspended indefinitely due to COVID. I guess I can either scrounge another dummy load, or do the calibration band-by-band manually. > From frantz at pwpconsult.com Sat Jul 11 22:36:21 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Sat, 11 Jul 2020 22:36:21 -0400 Subject: [Elecraft] KX3 power out In-Reply-To: <1ef5fed7-dc96-e106-2fa5-b7aaeb877b7c@inkbox.net> Message-ID: I believe that the KX3 does not have bypass relays in its ATU.

The KX3 will definitely cut way back on power out if it sees a mismatched load or a line voltage drop. I use my KX3 to tune a screwdriver antenna. I normally set the power out to about 3W, but sometimes forget and leave it at 15W. When matched, it puts out a full 15W. When it sees a high SWR, it will cut back to a few watts. I have the tuner bypassed. The KX3 will show you what it sees as the SWR as well as the power, and you can also look at reflected power on the Bird. Hopefully those will tell you something. 73, Mark W7MLG From vfo77 at inkbox.net Sun Jul 12 01:14:27 2020 From: vfo77 at inkbox.net (Frank O'Donnell) Date: Sat, 11 Jul 2020 22:14:27 -0700 Subject: [Elecraft] KX3 power out In-Reply-To: References: <07eb80bf-c36b-e2f8-b4f8-52144e84b09c@inkbox.net> <23d1adb6-6ec5-74ee-a42c-ebc14ee90a18@inkbox.net> Message-ID: <4bc6adab-fa24-25d8-6239-aaf138c4feaf@inkbox.net> On the KX3 display, the voltage is 14.3v at idle, 13.8v key-down.

I'm still baffled at why putting the ATU on auto and tapping to tune would cause the wattmeter to show TPO at 25 watts.

The reason is because I check the radio is not coming out with the proper power (test performed with dummy load and PWR-SWR meter Daiwa). "OUT" is at 2.0W, and I can see, on the power meter, 1W. I proceeded by removing the antenna tunner module, to be able to access L1, ... L6 (filter board for 40/20 mts band). However after this, when I try to calibrate the RF filters, I can only get 0.1 W when I put the K1 in tune mode. I check again the "OUT", and I stay 2W. If I reinstall the internal antenna tuner, the radio returns to the initial behavior (only 1W when "OUT" has been set to 2.0W). Can someone guide me on how I should perform the power realignment process?.

Message-ID: <4A64FD15-0130-4891-8897-33F482A9239F@elecraft.com> I have a friend about my age who got into amateur radio only a few years ago. Like many of us, he was enthusiastic about the technology. Intrigued with DX. I showed him my station; we talked endlessly about gear. Later, I helped him put up a simple wire antenna. Then, when his license arrived, he dove straight into FT8 and didn't look back. Within days, he'd worked all states, then DXCC. He'd bag a few rare ones over a light lunch, then pat his laptop on the back and congratulate his software app for its near-mythical ability to extract weak signals out of noise. Within weeks, he'd mastered everything there was to know about this glorious new hobby. Point. Click. In this new world order, those of us who took the longer, slower path to ionospheric enlightenment -- and who still occasionally enjoy making waves by hand -- often fail to explain why. I had failed to explain it to my friend. Even as hints of his boredom crept in, creating an opening, the best argument I'd made for trying CW was that he could do it without a computer. Coming in a weak second was the notion that CW was the original digital mode. For obvious reasons, I didn't bother with the classic argument about CW's signal-to-noise advantage over SSB. I had all but given up. Then, in a moment of delayed clarity, I decided on a different approach. I invited him to a weekday brunch. A bit of an escape. He willingly took the bait. On the appointed day, arriving at his workplace, I bypassed the lobby's glistening elevators and climbed the four flights of stairs to his office. I insisted we take the stairs down, too. "Why?" he asked. "And how'd you get up here so fast?" I pointed out that I always chose stairs, when possible. That's why I wasn't out of breath. We hustled down, jockeying for position, and emerged on the ground floor invigorated by the effort. "So, where are we going?" he asked. We'd been to every overrated twenty-dollar burger venue at least twice. I replied that we'd be going someplace we'd never tried. My kitchen. When we arrived, I put him to work chopping onions and broccoli and squeezing oranges while I whipped eggs into a froth and grated Swiss cheese. We ate our omelettes outside, in full sun and a cool breeze. "What's for desert?" he asked. "Isn't there a frozen yogurt place a two-minute drive from here?" I had something else in mind. Back in the kitchen, I handed him a water bottle, then strapped on a small pack I'd prepared earlier. We walked a mile or so through my neighborhood, admiring the houses' varied architecture, ending up (as planned) at a local park festooned with blackberry bushes. The most accessible branches had been picked clean, but with teamwork and persistence we were able to gather several large handfuls of fat, ripe berries, which we devoured on the spot. We'd been poked and scratched but didn't care. "Doesn't brunch usually end with champagne?" he wondered aloud, admiring his wounds. Not this time. I pulled out two bottles of craft beer that I'd obtained from a neighbor in trade for repairing his ancient home stereo. Carlos had spent years crafting an American pilsner to die for, sweating every detail, including iconic, hand-painted labels. My friend accepted the bottle, then tried in vain to remove the cap. Not a twist-off. "Opener?" he said. I handed him a small pocket knife, an antique without specialty blades. He soon discovered it could not be used to remove the cap directly. He looked at me with a bemused expression, no doubt wondering what I had up my sleeve this time. I pointed out that we were surrounded by white oaks, a species known for its hard wood. He got the message, smiled, and began hunting. Within seconds he'd collected a small fallen branch. I watched as he used the knife to fashion a few inches of it into a passable bottle opener. We popped the caps, toasted his new-found skill, and traded stories of our misspent youths. "Oh, one more thing," I said. I pulled a KX2 out of my pack, along with two lengths of wire. Of course he knew everything there was to know about Elecraft, and me, so he wasn't surprised when I also pulled out the rig's attachable keyer paddle. We threw one wire in the closest tree and laid the other on the ground. He didn't have to ask whether I'd brought a laptop. We listened to CW signals up and down 20 meters, which was open to Europe at the time. As he tuned in each station, I copied for him using pencil and paper. He'd learned Morse code, but only at very slow speeds. After making a contact, I set the internal keyer speed to 10 words per minute and dialed power output to zero, for practice purposes, then showed him how to use the paddle. He smiled as he got the hang of it. Sending the full alphabet was a challenge, but he got there. The KX2 decoded and displayed his keying, providing confirmation. We'd blown through his allotted lunch break by a factor of three, so it was time to go. We coiled up the antenna wires, packed up, and walked back. As I drove him back to his employer, we made plans to get together again for a weekend hike. I could have just dropped him off, but we went back into the lobby together. Out of habit, he stopped in front of the elevator. Then he looked up. "OK," he said. "I get it. This CW thing. It's slow, it's hard to do well, and it takes years of practice." "Like hunting for your own food, or carving your own tools," I added. "Or cooking from scratch. Or brewing your own beer. Building your own radio. And you use more of your senses. Not just your eyes, but your ears. Your sense of touch." I nodded. Listening. Feeling. That was the radio I'd grown up with. "Of course it's harder to work DX with CW than with FT8," I reminded him, playing devil's advocate. "Is that what matters, though?" he asked. A longer discussion for another day. "Your call," I said. He gripped my shoulder and smiled, then reached toward the elevator's glowing, ivory colored button, framed by polished brass. The path most taken. Point. Click. "On second thought," he said, "I'll take the stairs." * * * Wayne, N6KR From dpbunte at gmail.com Sun Jul 12 11:19:49 2020 From: dpbunte at gmail.com (David Bunte) Date: Sun, 12 Jul 2020 11:19:49 -0400 Subject: [Elecraft] "On second thought, I'll take the stairs."

You're not the only one that has a ham friend like that either. Sometimes I get a bit frustrated when people ask me about the hobby and why I only operate CW and my explanation falls on deaf ears. I think I will have to try your approach to the situation and see if I can't get a few more interested. The stairs are another thing though - LOL. I'm 78 now with a very bad knee and don't walk or climb stairs very well any more (though I do still try) and I'm afraid most of the new hams I know that fit this category would leave me behind very quickly - hi hi. I learned to copy CW as a "Morse Intercept Operator" in the US Army back in 1961, later taught myself to send with both a keyer and bug (I still prefer the mechanical bug), got my ham license in 1963 and have never looked back. Still use CW 99.5 percent of the time and only use phone when absolutely necessary (mostly on the VHF/UHF FM repeaters).

Like Elecraft radios, it was well-crafted and had just the right amount of ?stuff.? I?ve been a ham for a little more than a year. I?ve worked quite a few stations using FT8 ? because that is about all I can do here at the house. If have S7-S9 noise because of ancient power equipment in my neighborhood. Phone is out of the question. So it was FT8 if I wanted to play radio at home. Most of my ops are portable. I go out on weekends or during the week when I can, set up a portable station, and talk to other operators. I?m a little shy, so I?m not much of a ragchewer. But I like the contests, QSOPs, and working special event stations. Last fall I enrolled in the CW Academy and completed Basic and Beginner. One of the mentors is running an ad hoc Intermediate class this summer. I?m up to about 10wpm now and continue practicing to get my copy speed up. I?m not good enough (yet) to run a frequency, but that?s my goal. There have been many times I just sat at the rig, in the field, and tuned the bands? just listening to the other stations. I find something comforting in knowing there are these operators out there, communicating in a simple fashion using a relatively simple technology. I?m hearing a few slow-code stations talking on 40m many evenings. If I?m home, I turn my web browser to one of the websdr sites and listen. On Wednesdays I can sometimes hear a few stations during the CWTs at home. I?ve even worked a few of them from home, with my slow, clumsy fist. I really dislike listening to stations on my home rig, an upgraded K3. Because of the noise, when I use NB/NR to get a better SNR, the tone is chopped up and does not sound pleasant to the ear, as it should. But it gives me the chance to work a couple of stations and it?s only an hour at a time, so I can tolerate it that long. But I am enjoying my radios. I don?t mind working portable at all. The weather is often nice here in northern Nevada and I like the outdoors. I am also enjoying the CW mode. In many respects I?m something of a purist and the CW mode appeals to that part of my personality. There is something clean about the tone of CW and well-sent More Code is quite musical. I also prefer the stairs? 73 de AG7TX David Thompson, AG7TX Jack of All Trades Master of None dbthompson at me.com > On Jul 12, 2020, at 08:07, Wayne Burdick wrote: > > I have a friend about my age who got into amateur radio only a few years ago.

I caught myself a few moments ago digging out my paddles with thoughts of dusting off my CW skills?

In-Reply-To: <4A64FD15-0130-4891-8897-33F482A9239F@elecraft.com> Message-ID: I love Wayne's story, which demonstrates how much more value you get from mastering activities that involve some difficulty. As others have pointed out, it is very well written too. However, sometimes those arguments don't work. When that happens, my favorite argument is: And how do you ask for 5 units of type O+ blood on FT4/8? I use FT4/8 frequently, but it always seems a bit like cheating because there is no good answer to the above question. Contesting and DXing started as practice for emergency communications, which is the reason many people give for getting their licenses. Emergency modes should allow for the above message. As an example, when operating in Field Day, it is legal (I think) to use a cell phone as a link to an Internat based time server. Does this make sense for an EmComm based event? One can argue about GPS based time sync or high stability clocks, but modes that require time sync seem fragile in an emergency situation. What happens if a CME has taken out the GPS? The good news is I made many CW contacts, along with some PSk31, RTTY, and voice contacts which don't have these problems. 73 Bill AE6JV On 7/12/20 at 11:07 AM, n6kr at elecraft.com (Wayne Burdick) wrote: >Within weeks, he'd mastered everything there was to know about >this glorious new hobby. >Point.

I've been busy. But I'm having fun now! I have? the K2 Owner's Manual Revision G, May 29, 2007. I also have Errata sheet Rev. G-1, Dec. 12, 2007. In the Front Panel section, page 27, the original instruction advises to use two spacers at each end when installing the LCD backlight diffuser to keep the diffuser exactly 1/8" above the PC board. The Errata sheet clarifies to use the spacers but remove them after soldering the diffuser into place. The issue is that the two spacers are 1/8" thick. The diffuser leads are exactly 1/8" long. This means with the spacers in place, the diffuser leads don't actually reach the solder holes. The lead ends are suspended just above the holes. If I actually manage to line everything up and use rubber bands to hold all in place while I solder (good luck!), the solder would need to bridge up to the ends of the diffuser leads for the soldered connections to hold. This doesn't seem like a good practice. Is there a newer errata sheet? Or am I not understanding this correctly?

Solder them from the top of the board - being careful so the iron does not touch anything but the leads and the solder pads. If the leads do not touch the solder pads, sand down a spacer so that it does just touch. If there are rough spots on the spacers, sand them off. 73, Don W3FPR On 7/12/2020 1:02 PM, zk2boy wrote: > I am just getting around to building my K2 that I purchased in 2008. > I've been busy.

Install the jumper in band board J8 between pins 1 and 8. If your K1 does not have a "K1/ATU" switch next to the BNC jack, you will have to re-install R36 on the bottom of the board - it should have been left with one leg still soldered. The lack of R36 connection is likely what is causing the difference between the OUT parameter and the actual power out. Be certain you connect a dummy load - do not use an antenna. 73, Don W3FPR On 7/12/2020 6:00 AM, W4RAM wrote: > I want to realign the output of my K1, the radio has an internal antenna > tuner.

My understanding is Auto is used to tune the antenna but you then switch to MAN to operate after the ATU tunes to your antenna (my KXPA100/KXTA100 works the same way). My original 2m module (kit) did not reach full output so I returned the module to Elecraft and they fixed it. But I still only see 2.5w output on my Bird meter with 25C element into Bird load. My guess the Bird is off calibration though 5% of 25 is 1.25w, so it could be just the limit of the Bird's accuracy. I use it to drive a 60w MOT amp that only needs 2w drive so all good. My KX3 only outputs 12w on HF but I haven't upgraded firmware so maybe that would increase to 15w. No matter as the KXPA100 only requires about 5.5w drive for 100w out on 80-10m and 8w provides 80w on 6m (which is normal). I think the ATU is kind of fussy at times and I have to redo the tuning to have it work right. I usually trust the power & SWR meter on the KXPA100 for day to day use. I have two Bird meters (one is permanently in my 2m-eme antenna line). A couple years ago I discovered the calibration limits of Bird elements when using a 250E element to measure my 150w 1296 amp. It only read 125w. But the element is rated for 400-1000 MHz and falls off above that (which explains the low reading). I now have a 600w amp on 1296 and use directional couplers and my HP432A mw power meter. The 250E and 500E are grossly inaccurate at 1296. BTW Bird dummy loads can be found on e-bay and other ham lists. They are rated to 1000 MHz. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From n6kr at elecraft.com Sun Jul 12 14:24:03 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 12 Jul 2020 11:24:03 -0700 Subject: [Elecraft] "On second thought, I'll take the stairs."

I am still a beginner in CW, so I?m not yet feeling ?competent". But I?m sure this list has plenty of them. I received this from CWOPS? CW Academy recently: >> For a number of reasons, we are having an enormous number of students signing up for the Sep/Oct 2020 semester. We are anticipating somewhere in the neighborhood of 600 to 700 plus students. As it now stands, we are very short of competent advisors. We currently have around 75 advisors and with our target of approximately five or six students per advisor class, we really could use about 40 to 50 more advisors. >> >> To that end, we see you are not signed up to take or teach a class this fall.

I had considered whether to pursue getting into HF and DX, and what radio in general could offer over more "instant-gratification" forms of communication like SMS. What I kept coming back to is the excitement of learning and figuring new things out, the challenge of making contact, and the human element. I feel like quick and easy texting has made conversation disposable, I remember when email was a once-a-day transmission via modem? or you had to write an actual letter to reach someone? the content of the transmission was far more considered, precisely because it took time and effort? and I think that effort made the message even more appreciated by the recipient. When I was younger, my physics teacher gave me a shortwave radio? I must have spent hours tuning that dial listening to voice transmissions and strange beeps and boops. Then I got busy with a career working in computers. I am definitely a tinkerer and gadget geek. Fast forward to today, I?ve re-discovered radio, got my license and my VHF/UHF HT? and I?m still intrigued by those far away signals? who?s out there sending them, and where are they coming from? 73, Steve KM6ZNZ > On Jul 12, 2020, at 8:07 AM, Wayne Burdick wrote: > > I have a friend about my age who got into amateur radio only a few years ago.

If you are interested in CW operation I encourage you to look at the CW Academy sponsored CWOps at CWops.org. There is a program to carry you from beginner to 25 WPM with proper instruction along the way. That KX3 is a great radio for CW or any other mode you wish to pursue. 73, Bill WE5P Comfortably Numb > On Jul 12, 2020, at 16:11, Steve Belunek wrote: > > ?Hi Wayne, > > As a new ham, having just joined this list and excitedly awaiting my first HF rig (a KX3), I really appreciate this perspective. > > I had considered whether to pursue getting into HF and DX, and what radio in general could offer over more "instant-gratification" forms of communication like SMS.

There's no part in it, no shape in it, that is not out of someone's mind [...] I've noticed that people who have never worked with steel have trouble seeing this?that the motorcycle is primarily a mental phenomenon.* They associate metal with given shapes?pipes, rods, girders, tools, parts?all of them fixed and inviolable., and think of it as primarily physical. But a person who does machining or foundry work or forger work or welding sees "steel" as having no shape at all. Steel can be any shape you want if you are skilled enough, and any shape but the one you want if you are not. Shapes, like this tappet, are what you arrive at, what you give to the steel. Steel has no more shape than this old pile of dirt on the engine here. *These shapes are all of someone's mind. That's important to see.* The steel? Hell, even the steel is out of someone's mind. There's no steel in nature. Anyone from the Bronze Age could have told you that. All nature has is a potential for steel. There's nothing else there.? ? Robert M. Pirsig, Zen and the Art of Motorcycle Maintenance: An Inquiry Into Values So, it's important to see a main reason why these radios are so excellent; because they come from the minds of people who can express their love and talent for cw in radio circuits, just as eloquently as Wayne does in his story.

Well, we all have a life history with radio. Mine began with a real-life crystal set, the kind with a chunk of galena and a whisker and a coil wound over an oatmeal box. Later, a Meissner regen receiver. Still later, my first transmitter was all home-brew, 6146 final -- worked the world with it and a Hallicrafters SX-96. I've tried FT8 and even WiresX, but neither one seems much like radio. The digital qso via an internet gateway seems particularly pointless, sorta like a zoom call with a completely random person.

Message-ID: Very well done Wayne! For what it's worth, when someone asks me why ham radio and CW in the era of cell phones and internet, I usually ask them the question "Why do people buy sailboats?". It's a great way to start the conversation, and I usually see lights go on. As you eloquently illustrated, there's a lot of charm and fun to be had by taking the old traditional paths rather than the freeway. It requires a lot of knowledge and skill to be a good CW operator or a sailor in a wind powered vessel.

It'll take me awhile to shake this image :) The argument for digital modes like FT8 is that they're reliable at or below the noise floor, making it possible to work lots of DX even if solar conditions are very poor. Simplicity of protocol is a side effect of this design. But it begs the question: Is nearly effortless DXing all ham radio is about? If at least some part of your on-air time is more visceral, more tangible, then -- some of us argue -- the overall experience can be more fulfilling.

Message-ID: I'm as old as many here but, unlike most here, I left amateur radio for 40 years after my initial teenage enthusiasm as a "G3". My 15-17 wpm copy capability and a reasonable fist with an English WT-8A were completely lost. When I started over I had to learn the alphabet almost from scratch. I see CW as a "means to an end" and, for me, the "end" is chasing DX. If the DX is working CW I'll call them with CW. If they are working FT8 then I'll call them with FT8. It now seems far more likely that the DX I need is working FT8 and not CW. Despite that, in my 8.5 years chasing DX as a "K", I have more DX confirmed using CW than with digital or phone. I still can't have a CW conversation at more than about 14 wpm and never rag-chew. No problem reading my own call at 35 wpm though, so happy to chase DX at that speed if that's the speed the DX wants to work. CW is just the "means". If I want a conversation I can use Skype. 73, Andy, k3wyc From frantz at pwpconsult.com Sun Jul 12 18:49:00 2020 From: frantz at pwpconsult.com (Bill Frantz) Date: Sun, 12 Jul 2020 18:49:00 -0400 Subject: [Elecraft] "On second thought, I'll take the stairs." In-Reply-To: Message-ID: I sympathise with Andy's view, but there's another way of looking at it: Suppose you like tha ancient art of conversation with strangers, which I do. In fact, I'm doing it now. Now, what strangers do you want to select from? There are the people next to you in line at the airport (or at least there were BC). There are the people on long distance trains. etc. But to select for people who are interested and knowledgable about radio communications, other hams are a pretty good choice. And what better place to find them than on the air? Yes, you can find them on this list, and we are blessed with some true experts. But what happens here is more like letter writing than conversation. For conversation you need faster response. Pick up a mic, key, or an interactive digital mode and have a conversation. 73 Bill AE6JV In this case CW, PSK, RTTY, SSB, FM etc. etc. etc. are close to the end itself.

Since I retired and downsized to an apartment with no tower or beam in an urban environment I find myself using those very weak signal modes. Still have the KPA500 and KAT500, but using that kind of power in an apartment is just not "neighbor friendly" so I am saving them in case I decide to move back to a less congested area or find a place I can set up a remote station. In the mean time there are those digital modes that I can get on and make some Qs on. Please do not denigrate these modes because there are a lot of people in similar situations. Yes, I would love to crank up the juice, spin the beam around and pound the green keys in plain old RTTY, but it just ain't happening right now. So let me make a few Qs now and then and remember when I had a "real ham station" making "real contacts". And if you don't like it I don't give a (insert your least favorite term here) what you think. Have a nice day. On Sun, Jul 12, 2020, 18:54 Lynn W.

I'm no expert, but I think that the coding could have enough error checking to allow busted message frames to be printed (or converted to CW) ... although of course with errors. The extra error processing would reduce the character count, though, all other things being equal. The point is that the digital signal processing behind FT8 is extremely powerful and could be adapted to other user formats with a lot more flexibility than we have with FT8. The hams who just dismiss FT8 out of hand really don't understand the broader weak signal applicability of it. 73, Dave AB7E On 7/12/2020 4:53 PM, Lynn W.

I see why people would want to go on a DXpedition. It's quite an adventure. I can understand certificate hunting, DXCC and all of that. I get the people who are totally into linking VHF/UHF via the Internet. There is a vast amount of fun building radios, and there are similar "homebrew" opportunities. I know, I've done a lot of homebrew software. Then there is slow-scan TV, and in some metropolitan areas, fast-scan TV. I spent many an evening Transmitter Hunting, but to many driving around on a rainy night with a 4 element 2m quad sticking out the window is excessive. I got my Extra so I could become a Volunteer Examiner. I know I've left out a lot, but it's all important to the hobby. Every single niche and variation. I'm simply not attracted to FT-8. I understand that someone has taken the ideas behind the low bandwidth encoding and etc. and turned it into something you can chat through, and that sounds like fun to me. As usually, YMMV. 73 -- Lynn On 7/12/20 5:32 PM, Rick NK7I wrote: > You?ve just defined the vast majority of DX (and DXpedition in particular) contacts. > > That doesn?t make less a part of ham radio. > > Rick NK7I > > Email spiel Czech corruptions happen > >> On Jul 12, 2020, at 4:54 PM, Lynn W.

I'm aware of JS8 and tried it more than a year ago, but it still has much of the rigidity of the WSJT-X user interface and isn't as basic as I think would be desirable. Think of it this way ... CW works fine as both a contest mode, DXing mode, and conversational mode.? Underlaying CW with a well configured digital signal processing scheme like that which is under FT8, except with a different user interface than either WSJT-X or JS8,? could be equally versatile but with maybe 6-8 db better S/N ... possibly by an even greater margin if the decoding allowed errors instead of being all or nothing. I'm not saying text-to-CW is the only way to reap the benefit of modern digital signal processing ... only using it as an example. People only interested in a contact will probably always prefer WSJT-X/FT8 because it does that very well, but both contesting and rag chewing could really use a different (simpler) structure while still utilizing the superior weak signal peformance of modern digital signal processing.? I guarantee that it is possible to do so. 73, Dave??

I have to use JFETs because I got rid of all my tube stuff due to lack of room. But of course I will continue to benefit from the DSP in my K3, and its keyer (although I have a bug that I use once in a while). But those things don't take away the connection to history, they make it better. The point for me isn't to use the same gear as they did in 1912, but to enter the Morse space as they did. If I can do it with equipment that is more stable and effective, so much the better.

Perhaps not directly. Preferences can always be strongly implied. I think it is inarguable that years back ARRL publications had a bias toward antennas that favored DX. DX is fine and perhaps that did keep more Novices in the ranks than would have otherwise stayed due to poor antennas. However, a low dipole antenna for the low bands was often derided as a "cloud warmer" without mention of why such an antenna might be useful. Perhaps it was the steady diet of Kurt N. Sterba in the now discontinued World Radio magazine as a Novice and Tech in the mid-80s that taught me that a low antenna on the low HF bands had a valuable use. I proved this to myself right at 35 years ago when I became active on the Novice bands and wanted to work the Kansas Slow Speed CW Net (QKS-SS). The vertical I had due to previously being convinced that I needed a DX antenna worked miserably for such close-in work as checking into a section net. I strung up a dipole that was almost too low and I was rewarded with very strong signals from within a few hundred miles on 80m. Working the section net was easy with that antenna. It wasn't until the quasi-military term Near Vertical Incident Skywave (NVIS) entered the amateur radio vernacular in the early '90s that "cloud warmers" became acceptable in literature printed in Newington. Denizens of low band section nets knew the secret decades before. Why do I use a K3 when over 90% of my operating time is spent on 75m nets these days? The QRM fighting features such as high and low cut with appropriate filtering and something about its receiver where I don't experience the fading other operators using other radios mention frequently. Perhaps it is my low doublet antenna that is overall a 3/4 wave on 75/80m that helps. > I don't know why some hams insist on fabricating controversy where there is > none.? It seems like the bulk of our American society is determined to be as > tribal as possible.? Sorry times we live in. There is a reason for that which is not apropos for this list. Suffice it to say that this has been the case for nearly the entirety of the existence of amateur radio and likely in other endeavors for centuries. A look at QST from the earliest decades show a bias toward traffic handling and as the shortwave spectrum was discovered slowly turned toward DXing. In later decades Emmcomm has assumed a greater stature while paradoxically traffic handling has almost been forgotten. Fact is that people will always have a bias toward their own interests. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."

I think the many changes since then have made it much less "rigid" and much more useful. In addition to plain old everyday ragchewing for example, it has the capability to auto-relay messages, store and forward messages, send to designated groups, interface with APRS and SMS messaging, etc. All functions that are not even remotely possible with FT8 or CW, for that matter. And do so at multiple speed levels that extend up into the 20+ wpm realm. All this can be done normally at very low power levels. 73 Lyn, W0LEN -----Original Message----- From: David Gilbert [mailto:ab7echo at gmail.com] Sent: Sunday, July 12, 2020 8:57 PM To: Lyn at LNAINC.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] FT8 - was "On Second Thought, I'll Take The Stairs" Not quite. I'm aware of JS8 and tried it more than a year ago, but it still has much of the rigidity of the WSJT-X user interface and isn't as basic as I think would be desirable. Think of it this way ... CW works fine as both a contest mode, DXing mode, and conversational mode. Underlaying CW with a well configured digital signal processing scheme like that which is under FT8, except with a different user interface than either WSJT-X or JS8, could be equally versatile but with maybe 6-8 db better S/N ... possibly by an even greater margin if the decoding allowed errors instead of being all or nothing. I'm not saying text-to-CW is the only way to reap the benefit of modern digital signal processing ... only using it as an example. People only interested in a contact will probably always prefer WSJT-X/FT8 because it does that very well, but both contesting and rag chewing could really use a different (simpler) structure while still utilizing the superior weak signal peformance of modern digital signal processing. I guarantee that it is possible to do so. 73, Dave AB7E On 7/12/2020 6:18 PM, Lyn Norstad wrote: > Enter JS8Call. > > All the technology of FT8, plus all of the conversationality of CW, RTTY and SSB rolled into one. > > If you haven't tried it, you really should.

I doubt any design change would be required. The display device would simply have its TX line disconnected and it would listen to KPA500 responses to utility polling. In my system that's done with a multiplexing relay so it can be used with or without the utility with no cable re-configuration. In my opinion the parameters that are useful when monitoring a KPA500 are PA dissipation and PA efficiency. This device displays neither.

I would not trust a Bird 43 or similar meter for any "Measurements" whatsoever. Especially if you cannot prove that the slugs and meter body were calibrated together. They are notoriously inaccurate, but are good for quick "power presence" indications, and "ball bark" VSWR checks. I honestly do not know why Bird 43's etc, are so coveted by the ham community, they are awful things for making measurements.. Note that the difference between 8W and 15W, is a bit less than 3dB. (2.73dB, or less than half an 'S' point!) And for 3 and 2.5W it's 0.79dB? (Less than 1dB is not bad.) Also, how good is the MFJ load at VHF, VSWR wise.? The spec says 1.5:1 above 30MHz.?

Each to his own of course but, for me, the pleasure of making a contact has almost nothing to do with the mode used and almost everything to do with how much I wanted to contact that station. I say "almost" because I still enjoy CW more than other modes. How many would refuse to work Bouvet if FT8 is the only mode they choose to use when/if it is activated?

In-Reply-To: References: Message-ID: <7A48B173-58B1-40E5-844A-2EE91020A67A@gmail.com> This is correct...there is skill and strategy involved with FT8. Sure, on a relatively empty band you can set and forget and let the software do all the work. Blindly call CQ and let others come find you. Yes, that could be construed as watching paint dry or grass growing. How often does an empty band happen? For me, and the times I?m on, never. Our little segment of FT8 is usually jammed from side to side with stations. At times it?s hard to get a word in edgewise. ;-) (And don?t get me started on the ops who grossly over modulate, spill out and take up half of our space?) If there?s a specific station you want to work, there is strategy and timing involved to increase your chances of making it into their decode window as a red line. It?s not rocket science, but it?s not Ronco Ron Popeil (?set it and forget it?) either. One can experiment with which window to start calling in, and moving the transmit point around, often to good effect. I have only gradually become aware of the strategy and timing aspects of FT8 by using it a lot. Seeing what works and what doesn?t. And I?m still learning by doing. I offer this only as point of consideration for those who may not have thought about it in this way. I?m not necessarily an FT8 evangelist. I love other aspects of the hobby as much or more. The beauty of this hobby is that you can take what you like and leave the rest for someone else. 73, David - N5DCH > On Jul 13, 2020, at 9:48 AM, Carl Yaffey wrote: > > My two cents: FT8 is a bit more than using a computer to make contacts.

Although I do have a gripe (is it FT4?) with the software that has arbitrarily plopped its users down in what was just a few months ago the home of mostly CW QRP activity on some bands. There does seem to be a need for coordination. Of course, I?m also old enough to remember, when SSB was beginning its surge because of the growing availability of good commercial gear. At the time, SSB was mostly relegated to the lower 25 KHz of most phone bands. AM ops would jump on anyone branching out from the then ?SSB ghetto?. Times change and nothing changes .. it just morphs into new groups co-opting spectrum from someone else :-) Still ?

I have learned that to work DX with a modest station such as I have, some skill in signal placement and timing is important.? Unfortunately, FT8 removes the timing trick, but signal placement does make a difference. My gripes with the mode is that it's too easy for DX stations to plop down on an FT8 freq and never check propagation or operate on traditional modes.? Another is that ARRL hasn't seen fit to create a separate DXCC award for these modes, but has lumped it in with RTTY (which has been downgraded to "Digital").? My DXCC certificate says, "RTTY" and I want to keep it that way. Wes? N7WS On 7/13/2020 8:48 AM, Carl Yaffey wrote: > My two cents: FT8 is a bit more than using a computer to make contacts.

It doesn't matter the mode, ties into history will still exist and can be honored (or ignored), even if elements are destroyed (statues or old unused modes).? And ham radio excels at exploring modes and methods.? FT8 (and RTTY before that) is merely a stopping point on the line of history, something 'better' will come along (always has, always will, a constant) to fill the (momentary) needs. The primary advantage (to some) of CW or phone is that it's human brain effort and skill, via the radio technology, that gives a sense of accomplishment (pride) while for some including the ties to history, the paths taken to get here.? For others, a complete technological contact with minimal effort, is what they seek and the world of ham radio allows that too. All modes are valid and equal; just as casual, contest or rapid fire DX appeals to some, it suits the needs and purpose of the operator; to ENJOY what is available. My satisfaction comes from using different modes (lately FT8 while it's popular AND CW and phone) to prove access to all parts of the planet (DXing) with a station that I assembled and built from what I could afford or manage to do the best (sometimes easiest) I can manage.? My 'competition' is me, my motivation is always to do better.? I confine it with other limits too (budget, space used) because I don't want numerous towers or a super station and because that would affect my other enjoyable concerns (the view for one). My preference is for a complete, simple station but that also means a group of single point failures exists (one of my choices). If another has different ideals, there is room for that too, it's a personal set of choices. Rick NK7I On 7/13/2020 12:59 AM, David Gilbert wrote: > > Fine, but that demarcation is pretty arbitrary.?

The only issue I've found is that I need to make sure I don't play with the audio settings on the laptop after I've logged in, as it also affects the audio settings on the main PC. I mute the laptop audio first and then log on. Otherwise, I have to open the sound control (Windows 10) and change the speaker setting to get reset transmit drive levels. Also remember to set a personal password under options and allow "easy access" to your main PC.

Doing things the same way they were done a hundred years ago may make a "connection" for you. But hams are supposed to innovate, invent and increase the knowledge. So you buy or build equipment with way more ability than to send simple CW, so you can do simple CW? Yes, CW is great stuff, but it sure isn't innovative, nor does in increase the knowledge of communication.

I can give you some troubleshooting information if you are willing to hang in there with me. Eliminate the "[Elecraft]" from the subject line and reply to me directly (not to the list). Relay K15 is common on all those bands, but not on 80 and 40m, but that does not explain why 15 meters is OK. Check the resistance between pins 1 and 10 of all 3 relays - that is the coil resistance, and if I recall, it is about 235 ohms. Check that C73 and C74 are the correct values. If that does not reveal the problem, you will have to measure the open/closed state of the relays for the next step. Can you find those relays on the schematic? They are all shown in the reset state. 73, Don W3FPR On 7/13/2020 2:52 PM, Keith Hamilton wrote: > I am having trouble with the K2 VCO alignment.

Before I start, I'll say that each mode has it's advantages, and so I am glad to have QSOs from all the ones I mention below in my log. There are a number of measures of "goodness" for modes. They include: Bandwidth, ease of tuning, complexity of equipment, noise suppression, signal awareness, features, etc. While some of these are obvious, others deserve some explanation. Noise suppression measures how easy it is to understand a message. FM is really good here. Signal awareness is a measure of how easy it is to notice other signals on your frequency. These signals can be your QSO partner trying to get your attention, or other stations. Full break-in CW is about as good as it gets while FT4/8 with its rigid time slots is about as bad as it gets. I think that bandwidth used is an important factor. When operators complain that people using a mode with 50 or 100 Hz bandwidth are using up "their" spectrum, I'm not very sympathetic. In amateur radio, it's our spectrum. If we don't use spectrum, it may become BigCommCorp's spectrum. (I AM in favor of following well thought out band plans.) There are the wide band modes: AM, FM, digital voice, SSB -- arbitrarily any thing over 250 Hz -- the width of my narrow filter. AM is a classic mode, and goes well with your Collins or Drake equipment. It is easy to tune and does a nice job of producing the heterodynes or yore. With 6 or more KHz of bandwidth it is quite wide. FM is very popular on VHF and above, but is even more of a spectrum hog than AM. It is easy to tune, and tends to have very low noise. Receivers tend to lock on to the strongest signal on the frequency, which can be an advantage or a disadvantage. The FAA went to AM for airplane radios to be able to hear a weak station as well as a strong one on the same frequency. Particularly on 2M, we are running out of bandwidth. Converting to a more bandwidth efficient mode would be an option, but consider all those then useless Baofengs, Yaesus, iComs, etc. The change over wouldn't be pretty. SSB is our workhorse for HF voice. We can understand communications in a 2 KHz bandwidth, although 2.7 KHz is easier on the ears. It is noisy and hard to tune. Digital voice - Doesn't yet have critical mass on HF. Might be nice, but probably won't work well at ESP signal levels. Can be slightly narrower bandwidth than SSB. Can have features like automatic message forwarding, digital streams at the same time as a voice stream etc. Just look at what the proprietary Yaesu and iCom modes do on VHF/UHF. They are not simple to set up or use, but they are loaded with features. Amateur TV etc. are proof that amateur radio is a very big tent. So now we have the narrow bandwidth modes. I'm only going to mention a few of them -- there are so many. CW is the classic. I'm glad people don't still use spark gap transmitters to enjoy the full retro-experience. It has the great advantage of needing very little in the way of equipment. A Rockmite is a large complex radio compared with the minimum of a simple transmitter with a regen receiver. It has the disadvantage of requiring a lot of operator skill. Those operators who have the skill are rightfully proud of their abilities. When you apply modern technology to the problem you can get something like a KX2 which can send/receive CW, tune your antenna, and log your QSOs == all in a package which will fit in a coat pocket. Another advantage of CW, with a modern radio, is that you can switch between receive and transmit quickly enough to determine if someone is trying to transmit on your frequency while you are still sending. RTTY is the classic digital mode. It needs a computer or a Teletype machine to decode and encode the signals. It is error prone, so in a contest you frequently have to send calls twice for redundancy. It is also quite wide for a narrow mode. You can have some interesting fun with RTTY. It is possible to interleave stations where the mark frequency of one station is between the mark and space frequencies of another, which goes to show that 170 Hz is wider than needed. Since transmissions aren't synchronized, it is possible to notice someone else transmitting on the same frequency as you, but noticing them is nowhere as likely as with CW. An amusing story: In a contest I heard 2 stations interleaving RTTY CQs on 20M. They were on exactly the same frequency and their mutual sync was perfect. I think they were in each other's skip zone. I managed to work both of them. The PSK modes were designed for rag chewing and require a computer. That computer is built into some radios, e.g. K3, KX3, KX2. PSK31 uses 31 Hz of bandwidth. Like the FT modes, they like to have a number of users in a 2000 to 4000 Hz chunk of spectrum. You might be able to cram 13 or so stations in a 1K bandwidth. There are some error detecting PSK modes, but as far as I can tell, no one uses them. The FT4/8 modes are the most sophisticated modes in common use. They require a computer, but are the only modes that can successfully decode two overlapping signals. They work several dB below the noise floor, so are attractive with low power, bad antennas, or high local RF noise. The only way to discover if you are trying to transmit through another strong signal is to pause sending. To slightly twist a famous quote attributed to Willie Sutton, I go to FT8 'cause that's where the stations are. The nearly fully automatic features were also very nice when I was physically wiped out from my cancer treatments, but still wanted to get on the air to improve my psychology. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)348-7900 | services.

Look for any evidence of a PC trace running on the other side of the board to that same pin. If there is, hopefully simply soldering on that side of the board may be OK, but if not, a wire on that side of the board may be necessary as well. The board uses thru-plated holes which carry signals from one side of the board to the other, some of which have components mounted in them. If you lifted a trace, you likely also destroyed the thru-plating, so be aware that you may have to do some repair on both sides of the board. This is all just general information, I do not have the particulars of the signal line in question. 73, Don W3FPR On 7/13/2020 5:17 PM, Jerry Ford wrote: > Good afternoon all: > > Gang: I need some advise from anyone familiar with the KX3 > control board. > > I replaced the encoder for AF/RF on my radio and while doing that, > I managed to lift the trace that runs under that encoder. > > Can anyone tell me where that trace goes ??? > > It run's under the encoder and the capacitors that are between Z2 and Z3. > > I pulled up the schematic and that trace should be the SWCOM.

You can check to see if the coils are intact if you measure the resistance between pins 1 and 10 for each. It should be around 230 ohms or so. If you find one open or well away from that resistance, then it would indicate a bad coil on that relay. You can also measure the intended path through the relays for each band and make sure there are no unintended paths. If you can read the schematic, it shows the path with each relay in it's reset state. You would need to consult the table in Appendix B to see which relay(s) are active for a respective band and you can then measure the continuity of the intended path. You should also check any unintended paths which could indicate a problem. As Don stated, this is not a fun problem to find and will take some good debugging skills. So far, everything you've indicated seems to suggest the PLL oscillator and VCO circuits are working properly, but the range selection area is not producing the proper capacitance to allow the VCO to produce the proper frequency on those bands you indicated. If reading the schematic is a problem, let us know and I am sure between Don and myself, we can give you some step by step instructions for tracing through this problem. 73, Dave W8FGU ------ Original Message ------ From: "Keith Hamilton" To: elecraft at mailman.qth.net Sent: 7/13/2020 9:34:03 PM Subject: [Elecraft] Fwd: Re[2]: K2 7747 VCO alignment problem >---------- Forwarded message --------- >From: Keith Hamilton >Date: Mon, Jul 13, 2020 at 9:19 PM >Subject: Re: Re[2]: [Elecraft] K2 7747 VCO alignment problem >To: Dave Van Wallaghen > > >Dave > >Yes the frequency changes when turning the VFO knob when measuring with CAL >FCTR on TP1. > >I have checked the markings on C71, C72, C73, and C74 (C75 is not installed >yet).

Any technology which allows one to work weaker signals with lower power is going to make DXCC easier. Even using CW it is infinitely easier to work DXCC on multiple bands these days than back in the fifties, well maybe I will make an exception for the 1958 era. There are so many aids and radios are better. This is a technological hobby and now the guy with the apartment and balcony might actually work DXCC. Viva engineering. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dauer, Edward Sent: Monday 13 July 2020 15:39 To: elecraft at mailman.qth.net; Victor Rosenthal 4X6GP Subject: [Elecraft] "On Second Thought, I'll Take The Stairs I agree fully with Victor; though the difference may be even simpler: Making a QSO using CW is a ham doing something with a radio.

When I make a CW contact, even if its total content is "ENN TU", I am connected to history, to Jack Phillips on the Titanic, to all of the military traffic men and airborne radio operators of WWII, to the operators on the merchant ships on the high seas and the Great Lakes, and to all the hams of the past, even Mr. Marconi, the first ham. I like hearing the propagation change with my own ears and struggling to capture an ESP-level call. I like the feel of the key and the sound of the code. I like the idea that there is another person like me at the other end with his or her hand on a key. I consider myself extremely lucky to have caught the bug at a young age and developed the skill needed to make CW as transparent to me as my mother tongue.

A chirp is a change in frequency of the transmitted signal. It is not the same as a click, which is a wide signal caused by too-short rise and fall times of the keyed envelope, or a badly shaped envelope. You can see the envelope shape on an oscilloscope. But the change in frequency caused by a chirp is very small in comparison with the frequency of the signal. The way to detect a chirp is to listen to the transmitted signal on a second receiver. Your ear is very sensitive to changes in pitch. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

It can also be cause by poor decoupling/loading of the oscillator circuit, but in the case of a well-designed circuit like the K2, this would normally only arise with misplaced components or poor connections.

If you can hear the change, then the change can be seen on an FFT. At least that would give a sense of whether the shift is up or down, if it is difficult to tell by listening. An FFT could also be applied to the RF, but, as Victor mentioned, the shift is small wrt the TX freq. It is NOT small wrt the decoded audio, however, which is why it was reported. So an FFT may well find it. There are different ways to get that analysis, and might not be worth the effort. One method would be to use a modern scope with FFT; another, a software scope such as the Zeitnitz scope; another might be fldigi. In the last two cases, you'd have to pipe the audio...that is the RX decoded audio...into the audio line in on a computer. But you still have to find out why...so maybe this FFT business isn't worth the effort...because you still then have to find the /cause/, even though you now have a pretty good idea where to look.

I worked DXCC as a Novice in 1957-58, all on 15 CW. It's true that signals were popping in from all over the world at the time. But the level and type of activity were completely different, of course. I worked many countries still deemed to be rare via QSOs with local hams (e.g. Johnston Island) or visiting scientists (e.g. Amsterdam Island), but only a couple via DXpeditions (e.g. Navassa). Often you'd have an exchange of name and qth, even with rare DX when others were waiting. You found DX by tuning and listening, and most QSLing was via direct mail. A different world. Now with clusters and micro-QSOs (5nn tu) you can knock off DXCC within 24 hours during a contest. Which is more fun? I dunno. Either way, hearing your call come back from the other edge of the world can give a little jolt of adrenaline, no matter how many times you've done it. I don't get any jolt seeing my call on the FT8 scroll. 73, Tony KT0NY From nr4c at widomaker.com Tue Jul 14 14:26:36 2020 From: nr4c at widomaker.com (Nr4c) Date: Tue, 14 Jul 2020 14:26:36 -0400 Subject: [Elecraft] Replace backup battery CR2032 in a K3 In-Reply-To: <6f55f162f44aaa20ed25533a3d241e14@xs4all.nl> References: <6f55f162f44aaa20ed25533a3d241e14@xs4all.nl> Message-ID: Don?t get too excited.

If you need an attenuator, try a 100k in series with the cable and a 10k from the line to ground. Those values are high enough not to interfere with the mic. Adjust the value of the 100k so you just light the ALC one bar. You may have to turn compression off if you do not get a clear DTMF signal out of the RF. The alternative is to get a DTMF microphone and rewire its plug to match your K2 mic configuration. 73, Don W3FPR On 7/14/2020 4:22 PM, Phil Kane wrote: > > I need to interface a DTMF pad to the mic input for special-purpose > signaling but I have not yet found a desk mic that has DTMF capability > built-in.

At least that would give a sense of whether the shift is up or down, if it is difficult to tell by listening. An FFT could also be applied to the RF, but, as Victor mentioned, the shift is small wrt the TX freq. It is NOT small wrt the decoded audio, however, which is why it was reported. So an FFT may well find it. There are different ways to get that analysis, and might not be worth the effort. One method would be to use a modern scope with FFT; another, a software scope such as the Zeitnitz scope; another might be fldigi. In the last two cases, you'd have to pipe the audio...that is the RX decoded audio...into the audio line in on a computer. > > But you still have to find out why...so maybe this FFT business isn't worth the effort...because you still then have to find the /cause/, even though you now have a pretty good idea where to look. > >> On 2020-07-14 18:15:+1000, you wrote: >> Generally a chirp would be due to an unstable power supply, resistance in >> the fuse holder, etc..

It also allows rotor control and AC power control turn turn various equipment on & off. This is accessible from any web browser, local or remote including smartphones. Definitely helps running remote. In the shack I run it on my iPad. A picture of the dashboard can be seen at the link below. It runs on a gui program,ing software on th e Pi called Node Red. We nave a groups.io group https://groups.io/g/nodered-hamradio It is open to all hams and we have flows supporting various ancillary ham equipment. I am currently writing a flow for the W2 wattmeter.

Yes, CW is great stuff, but it sure isn't innovative, nor does in increase the knowledge of communication. As a group we should encourage others to explore new communications systems, not denigrate them as "not REAL HAM RADIO". Some of you people should be ashamed of yourselves for your attitudes. We do not want Amateur Radio to die with our generation, so we should encourage new folks to do new things, not talk down to them because they don't choose to spend 99% of their operating time pounding brass.

At least that would give a sense of whether the shift is up or down, if it is difficult to tell by listening. An FFT could also be applied to the RF, but, as Victor mentioned, the shift is small wrt the TX freq. It is NOT small wrt the decoded audio, however, which is why it was reported. So an FFT may well find it. There are different ways to get that analysis, and might not be worth the effort. One method would be to use a modern scope with FFT; another, a software scope such as the Zeitnitz scope; another might be fldigi. In the last two cases, you'd have to pipe the audio...that is the RX decoded audio...into the audio line in on a computer. >> >> But you still have to find out why...so maybe this FFT business isn't worth the effort...because you still then have to find the /cause/, even though you now have a pretty good idea where to look. >> >>>> On 2020-07-14 18:15:+1000, you wrote: >>> Generally a chirp would be due to an unstable power supply, resistance in >>> the fuse holder, etc..

Remove the hand key, paddles, any PTT switch or footswitch and microphone to see if the Error goes away. If things are then OK, plug each one in one at a time and do a power cycle - when the Error message occurs, you will know that the last thing you plugged in is causing the problem. 73, Don W3FPR On 7/14/2020 3:02 PM, David F.

We took it in turns to be the Run station every 4 hours and I was using a 40M 2-El yagi at 60ft. I noticed that every 30-60mins, I needed to do a re-tune on the KPA1500 to keep the SWR at or near to 1.1:1, as it seemed to gradually creep up over time. The amp temp peaked at 70C but was mostly at about 55C. The SWR never got above 1.5:1 using KPA1500 screen but I know that the yagi was really presenting about 1.6:1 at the run frequency. When not operating as the Run station the other Op was in Partner mode spotting mults & helping with call identification. We were using the WinTest logging program as this enables us to private network with the other UK HQ stations (one on CW & one on SSB for each contest band ie. a total 12 stations at any one time, plus Partners). Because of Covid, this year we were all single Ops working from home rather than just a few multi op stations. My K3S & the KPA1500 worked faultlessly for the 24hours as did Wintest but I wonder what was the cause of the SWR increasing over time & needing a re-tune? 73 Ray G3XLG From k5rhd.73 at gmail.com Wed Jul 15 10:36:46 2020 From: k5rhd.73 at gmail.com (Randy Diddel) Date: Wed, 15 Jul 2020 08:36:46 -0600 Subject: [Elecraft] Calibrating RX on the K144XV Message-ID: <669BA91B-AB38-4A9A-B7C6-83DA33D4A970@gmail.com> Hi all, I have recently installed a K144XV in my K3s. From the factory, the offset value in the lower part of the band is +3.29 however, I tune into the Beam Spinner?s net every morning here in the Denver area on 144.200 however, with the factory recommendation, I have to tune 144.199.75 to hear stations clearly. Tuning the K3s?s VFO to 144.200, I have to change the offset to about +3.59 and then everyone sounds good and are ?on frequency.? There are several stations with have 9700?s so I would think they would be bang-on. So, should I set the offset by ear, should I recalibrate, or ??? I do own an XG3 so if I knew how to properly calibrate it, I could go that way too. Any help is appreciated! 73 K5RHD /randy From w8fn at windstream.net Wed Jul 15 10:38:39 2020 From: w8fn at windstream.net (Randy Farmer) Date: Wed, 15 Jul 2020 10:38:39 -0400 Subject: [Elecraft] KPA500 and VSWR Message-ID: <6073a9f0-8034-c29f-18f0-866e896fd64b@windstream.net> I just finished the 1300Z session of the CWops CWT and thought I'd pass on an observation on the KPA500. When I'm operating in contest mode, one of the things I like to keep an eye on is the KPA500 PA temperature, as monitored via WIN4K3. (WIN4K3 manages the multiple connections for CAT data needed to run my heavily automated SO2R station.) For the past few weeks, my regular strategy has been to run continuously in the early CWT sessions, usually on 40 meters. Late last week I made a tweak to my 80-40 inverted V antenna that resulted in raising it around 15 feet from its previous height of around 40 feet. As a result of this change, the 40 meter VSWR at the transmitter produced by my KAT500 dropped from about 1.4:1 indicated to 1.04 indicated on a well-calibrated LPA-100A. At the duty cycle of constant run operation at around 34 WPM, the PA temperature was previously running in the very high 50s, sometimes getting to 60? or even 61?. I'm actually slightly exceeding the amp's 500W output rating, since I set the drive to produce 500W as measured at the output side of my switched bank of Low Band Systems bandpass filters. With the lower VSWR, I never saw the PA temperature exceed 50?. I suppose this shouldn't come as a surprise, but it does show the PA heating effects of even moderate load mismatches on a solid state amplifier designed for a 50 Ohm load. Just an anecdote that some may find interesting. 73...

Yes, CW is great stuff, but it sure isn't innovative, nor does in increase the knowledge of communication. As a group we should encourage others to explore new communications systems, not denigrate them as "not REAL HAM RADIO". Some of you people should be ashamed of yourselves for your attitudes. We do not want Amateur Radio to die with our generation, so we should encourage new folks to do new things, not talk down to them because they don't choose to spend 99% of their operating time pounding brass.

At least that would give a sense of whether the shift is up or down, if it is difficult to tell by listening. An FFT could also be applied to the RF, but, as Victor mentioned, the shift is small wrt the TX freq. It is NOT small wrt the decoded audio, however, which is why it was reported. So an FFT may well find it. There are different ways to get that analysis, and might not be worth the effort. One method would be to use a modern scope with FFT; another, a software scope such as the Zeitnitz scope; another might be fldigi. In the last two cases, you'd have to pipe the audio...that is the RX decoded audio...into the audio line in on a computer. >> >> But you still have to find out why...so maybe this FFT business isn't worth the effort...because you still then have to find the /cause/, even though you now have a pretty good idea where to look. >> >>> On 2020-07-14 18:15:+1000, you wrote: >>> Generally a chirp would be due to an unstable power supply, resistance in >>> the fuse holder, etc..

The reason was because although the Yagi was tuned to resonate at about 7.130MHz it unfortunately has a rather narrow bandwidth. I needed to operate SSB in this contest in ITU Region 1 SSB, which is between 7.080MHz and 7.200MHZ. At 7.080MHz the SWR (with tuner bypassed) was 1.75:1 & at 7.200 was 1.95:1. I would be operating at power so I preferred to tune for 1.1:1. Yes I know the Yagi is not very good with that narrow bandwidth, but it is what it is. Normally I operate CW only on 40M & tune it to 7.030 with the bandwidth covering the preferred Region 1 CW portion of the band ie7.000 to 7.040 and the tuner is not needed. 73 Ray G3XLG From jim at jtmiller.com Wed Jul 15 11:48:05 2020 From: jim at jtmiller.com (Jim Miller) Date: Wed, 15 Jul 2020 11:48:05 -0400 Subject: [Elecraft] KPA1500 in the IARU Contest Last weekend In-Reply-To: <5f0f24a1.1c69fb81.494a8.1b86SMTPIN_ADDED_BROKEN@mx.google.com> References: <5f0f24a1.1c69fb81.494a8.1b86SMTPIN_ADDED_BROKEN@mx.google.com> Message-ID: Since it is so narrow I suspect it may be a trapped design or have loading coils which at 1500w may be heating and detuning as a result. 73 jim ab3cv On Wed, Jul 15, 2020 at 11:45 AM Ray Spreadbury via Elecraft < elecraft at mailman.qth.net> wrote: > > > A correspondent asked me why I needed to tune a resonant antenna. > The reason was because although the Yagi was tuned to resonate at about > 7.130MHz it unfortunately has a rather narrow bandwidth.

In short: I wish to operate digital modes from my control station to my remote station using K3 Twin mode of Remoterig setup (K3/0 Mini and K3 100). Have been using the setup for eight years using CW and SSB. Want to add Win4K3 to the control side. Want to (continue to) run N1MM+, DXLab Suite and add WSJT software on the control side. Can this be done? I also so have a Rigblaster that I can add to the mix. Do I need that or any other hardware or software? Below is an email sent to Tom at Win4K3 along with his response. -------- Original message -------- From: Darryl Hazelgren Date: 2020-07-15 1:07 p.m. (GMT-05:00) To: support at va2fsq.com Subject: Help with K3/0 remote setup Good morning Tom. I have been successfully running a remote station using an Elecraft K3 at the remote site and Elecraft K3/0, K3/0 Mini and K3 100 rigs at the control site in my condo, which is about 15 miles away from the remote site, for about eight years. I am using Remoterig RRC 1258 MkII boxes in the twin mode. Software is current. I run a KPA1500 which I control with the KPA1500 remote software. All antenna switching and rotating of Yagis is done with Green Heron and Array Solutions hardware and software. I am a DXer and Contester (Phone and CW) using N1MM+ and DXLab Suites. Now I want to start with the digital modes. The computers on both sides are Windows 10 with latest updates. I downloaded the latest Com0Com software and created three pairs for use with N1MM+, DXLab and WSJT. I downloaded the current Win4K3 app and began the setup. I am unable to advance beyond the Settings screen as I cannot get the K3/0 Mini drop down to connect. I have tried the virtual Com ports created by the Remoterig install app. I have connected to the USB port on the K3/0 Mini and verified that I have the latest version of software in the K3/0 Mini and noted the two ports the Mini uses. I have tried to connect via those. No joy. The last two pages of the instruct me to: "Save the settings and then from the Tools menu on the radio control screen pick "Enable K3 / 0?. I cannot get to the next screen to access the Tools menu. What am I missing? I have friends using Win4K3 and they love it. I?m looking forward to joining them... Answer from Tom, VA2FSQ: Hi I do not have a remote rig so I am not sure how this works. However, before you can go to the other connections, you must have win4k3 working and connected. Win4k3 uses pretty well all k3 commands including some undocumented ones for the k30 and I cannot say for sure of this will work with remote rig. I will say, you cannot connect to the radio with any virtual ports unless it is properly managed by remote rig. All other connections have to be through win4k3. 73 From juhakasari at gmail.com Wed Jul 15 15:19:46 2020 From: juhakasari at gmail.com (Juha - oh6os) Date: Wed, 15 Jul 2020 12:19:46 -0700 (MST) Subject: [Elecraft] KXV3 GAP1 Message-ID: <1594840786652-0.post@n2.nabble.com> Hello, I burned out GAP1 on KXV3 board, too much RF, hi.

If you do not find a problem with the relay coils, you should next check the contacts of relays K13, K14 and K15. On 20 meters, all the relays should be set - meaning you should have conductivity from pins 3 to 4 and not between pins 2 and 3. Check the other side of the relays - conductivity between pins 7 and 8, and open between pins 8 and 9 Then check 80 meters, only K13 should be set - so check K14 and K15 which are reset on that band - no conductivity between pins 4 and 3 and open between pins 2 and 3 Also check the other side, conductivity between pins 8 and 9 and open between 7 and 8. Then switch to 30 meters and you can check the reset state of K13 - Continuity between pins 2 and 3 and open between pins 3 and 4 Also conductivity between pins 8 and 9 and open between pins 7 and 8. If all that checks out, look again at the capacitor values of C71, C72, and C73. I know some of those capacitors are tight tucked between the relays, but bend them over a bit and use a good light and possibly a magnifier to read the markings. 73, Don W3FPR On 7/13/2020 11:00 PM, Keith Hamilton wrote: > OK Dave - > > I will check the relays as you suggest.

I've read your tutorials several times and they are an inspiration but it's just like linear amplifiers: you can't say an amplifier designed for intermittent service like ssb or cw is poorly designed because it doesn't pass the BOK test.

Anything you can slip on or off easily will not be water proof. I have used 3M rubber splicing tape to good effect over the years as it is self vulcanizing. Stretch it as you wrap it and it will fill the gaps. Then wrap it with a couple of layers of 3M Super 88 or 33+ electrical tape to protect it from uV. I've not tried what you're doing as I've covered splices (UHF to barrel to UHF, etc) with this method and the connection at the feedpoint of antennas. I've opened them years later and everything is clean and dry. The nice thing is that rubber will cut and peel away easier than the butyl of Coax Seal and such. I do use the butyl on connections for repeaters, hard line ground kits, and such!

Bigger core helps, Dave, No, it is NOT about size. It is about design of the entire antenna system, including the antenna, the feedline, and other parts needed to make the SYSTEM work. The principal characteristic of a common mode choke is the resistive component of its common mode impedance at the operating frequency(ies) where it will be used. Further, dissipation in the choke occurs at least as much in the WIRE that is wound around the core as in the core itself. There is another fundamental error in many antenna systems that ONLY looks at matching to the transmitter at the transmitter, ignoring the match between the antenna and the transmission line, using high impedance, parallel wire line, and using a random center-fed or off-center fed horizontal wire on all bands. Yes, the transmitter can be made to supply power to the feedline, yes, it will get to the antenna, and yes, it will radiate. But it may not receive all that well due to common mode current on the line from noise sources in our own homes and those of our neighbors. THAT is the problem with using a decades-old design for a world where there was 20 dB less noise than most of us face today. so a core that is OK for ssb > and cw might be undersized for AM or some data modes. Just like linear > amplifiers. So it is NOT the size of the core, it's the design of the antenna system. HFTA author and retired ARRL Antenna Book and Handbook editor Dean Straw, N6BV, published an excellent piece in QST 6-8 years ago called "Don't Blow Up Your Balun," in which he pointed out the differential mode dissipation in chokes, which can be extremely high if the choke is at a very high current point in a mismatched line. When he passed it to me for review, I noted that these losses were in addition to the common mode dissipation, and he revised the piece to reflect that. you can't > label something poorly designed because it doesn't pass the BOK test.

Yes, you have to worry about nearby objects unbalancing the antenna, which is less of a problem with a choked coax-fed dipole. But being able to use a very simple single antenna from (for example) 7 to 28 mHz. with relatively good efficiency is advantageous. My experiments with baluns seem to indicate that just using a current balun to go from an unbalanced transmitter or tuner to a balanced line works poorly unless you cancel out the reactance with a balanced network on the antenna side of the balun. All these tuners with "balanced" outputs provided by a balun (often a voltage balun) do not work well at all. My best result with balanced lines has been with the Johnson Matchbox. It's a shame that there doesn't seem to be an equivalent available today (and it wouldn't be easy to procure the parts to build one). 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 16/07/2020 6:26, Jim Brown wrote: > On 7/15/2020 1:36 PM, CUTTER DAVID wrote: >> It's all about size.?

I purchased mine at radio swaps from the guys that sell connectors. Also, try any of the wire/connector vendors on line.

I accept that wire size has an influence, but in my experience on smaller cores (UK limit is 400W) wound with RG316 I have observed the core getting hotter than the wire. BOK = Brick On Key. I think it was Alpha that used this in their advertising. So, in the protagonist's system, if he finds his swr climbing for no apparent reason, rather than blaming the linear it might simply be the core of the choke getting too hot with continuous use. A bigger core (or doubling up) helped me and it might help him. David G3UNA > On 16 July 2020 at 04:26 Jim Brown wrote: > > > On 7/15/2020 1:36 PM, CUTTER DAVID wrote: > > It's all about size.?

My question: I have lots of bags of K2 accessories unbuilt yet. Any chance somebody with a central database knows if there is a 15K resistor in an accessory kit that I could borrow and replace later?

Sometimes the vendor refuses to send to a post office box. What works then, at least in the USA, is to specify the street address plus the PO Box as if it was an apartment number. I always get a laugh when UPS refuses to accept the PO Box as a delivery address, but their Big Brown Truck pulls up to the PO loading dock anyway. This, of course, does not apply to items that the Postal Service will not handle, such as batteries and corrosive liquids. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From keith at elecraft.com Thu Jul 16 11:57:23 2020 From: keith at elecraft.com (Keith Trinity WE6R) Date: Thu, 16 Jul 2020 08:57:23 -0700 Subject: [Elecraft] Calibrating RX on the K144XV In-Reply-To: <669BA91B-AB38-4A9A-B7C6-83DA33D4A970@gmail.com> References: <669BA91B-AB38-4A9A-B7C6-83DA33D4A970@gmail.com> Message-ID: After it is at a stable temp, just change the offset number so it is on frequency. Do this below and above 146.000Mhz as there are two sections in the unit. Easiest way is to inject an exact 146.0000 signal, set the radio to fine, IE 46.00000 go into offset menu and tap SPOT. Then click down to 45.999999 on the radio and do the other side. Switch back and forth with the VFO, the tone should stay very close. Set the offsets accordingly if needed. If there is too much drift, then order the OPTIONAL K144XV Reflock board (installs inside the K144) and will lock it to the K3's main oscillator, which is more stable.

HFTA author and retired ARRL Antenna Book and Handbook editor Dean Straw, N6BV, published an excellent piece in QST 6-8 years ago called "Don't Blow Up Your Balun," in which he pointed out the differential mode dissipation in chokes, which can be extremely high if the choke is at a very high current point in a mismatched line. When he passed it to me for review, I noted that these losses were in addition to the common mode dissipation, and he revised the piece to reflect that. >> you can't >>> label something poorly designed because it doesn't pass the BOK test. >> BOK? >> 73, Jim K9YC > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to wunder at wunderwood.org From k1rdd73 at gmail.com Thu Jul 16 12:47:58 2020 From: k1rdd73 at gmail.com (Doug Daniels) Date: Thu, 16 Jul 2020 12:47:58 -0400 Subject: [Elecraft] Waterproof SO-239 covers In-Reply-To: References: Message-ID: Thanks for all the responses and suggestions.

I had to resort to FT8 to work Monaco to get on the Digital Honor Roll, with the other 330 having been on RTTY." Just to quickly add my input before the topic is canned. I'm not enamored with FT8 but just for grins, I conducted an FT8 experiment a few months ago to see how many countries I could work with no antenna terminated at the end of a broken open-feeder transmission line. That's right - no antenna, just a hunk of balanced open feeder line that sits unterminated on my backyard fence. Using a 100W rig with output power turned down to 20W, SWR is off-scale. I work on my own gear. If I blow it up, so be it. Over a few weeks I worked about 35 countries on 20m and 11 countries on 40m, all FT8 of course. No antenna and sky high SWR. By now, folks are thinking."yeah no antenna, but your line is the antenna, balanced or not." That's right. There's just enough imbalance between the two conductor feeders that the line has some radiation. The imbalance is caused by the usual culprits like proximity to aluminum gutters and some inherent imbalance between the rig and feeder. However, it just goes to show that skill to make FT8 DX contacts rests largely with the algorithm. Frankly, most of the skill needed is in learning to install and configure the WSJT-X software - which isn't difficult. As such, I find it amusing that anyone considers FT8 an accomplishment - and a semi-automatic one at that. But for those who feel it is an accomplishment, there's no point in denying their satisfaction.

I think he might have misspoken when suggesting using pliers to effect an extra quarter-turn on a PL-259 after first getting it finger-tight. The "quarter turn" idea most often refers to the trick of backing-off a screw "a quarter turn" and then re-tightening in order to break up corrosion.? More than one restorer has brought vintage equipment to life by doing nothing more than that. A second problem with using pliers to scrunch a PL-259 is the risk of permanently deforming the barrel making future removal difficult if not impossible. Plier-tightening has its place, but hardly more than the degree or two to which you alluded. Take care of that dandruff! 73, Kent?

Few ham antennas are perfectly balanced -- they are often unbalanced by their surroundings. For example, ground slope, unequal heights of the two halves, other conductors around the antenna, even vegetation. And yes, all elements of the antenna system, including the feedline, the antenna, and matching at both ends, contribute to the balance of the SYSTEM. THAT'S why it's wrong to talk about "balanced line," using "parallel wire" or 2-wire" line instead. 73, Jim K9YC From jim at audiosystemsgroup.com Thu Jul 16 16:18:09 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 16 Jul 2020 13:18:09 -0700 Subject: [Elecraft] K4 in production In-Reply-To: References: Message-ID: <77bc8d68-7f79-bdf8-c886-2bebd4c59ffe@audiosystemsgroup.com> On 7/16/2020 10:20 AM, Tox wrote: > The parts availability issue was supposed to have been resolved pre-covid.

No, misunderstanding/poor way of describing the problem. For good RF contact, the entire circumference of male and female connector must make solid and continuous contact. This can only happen if the teeth in the male connector fit within the corresponding gaps in the female connector. If that has been accomplished, wrench-tight may be less than a quarter turn, but it also depends on how strong your fingers are, and whether you are able to get a good grip on the connector. For example, I need more than a quarter turn with pliers in my fairly dense entry panel in the wall under my operating desk. And if the teeth are not properly mated, it's common to get more than a quarter turn when using the wrench. > > Also, I've never had a failure after simply applying a generous wrap of > self amalgamating tape, nothing else, to waterproof coax connectors.

We only tightened them hand (finger) tight. In may places pliers would have not fit any way. In black & white days we would want to be flat from DC to around 8 MHz with a smooth roll off to about 15 MHz. Later in color most of the video distribution amplifiers were flat to even 25 MHz. >From the late 60s to late 70s the connector density increased significantly and we went to BNC for video & later for even audio when we converted to digital audio distribution. In a typical studio plant any discontinuity in video coax tended to show up as a "ghost" in the video in black & white and in color the results could be only described as Technicolor gone wrong. We rarely had discontinuities - most of the time it was a poorly made connector or center migration due to too tight a bent in the coax. I don't ever recall that tightening a connector with pliers corrected these discontinuities. We solved the poorly made connectors by going to crimp style of connectors. When I became a Ham after retiring from Broadcasting - I had to go back to using UHF connectors. First tool I bought was a coax connector crimp tool! Unfortunately I could not afford the $300 to $500 tools for each coax size that we had at work. I had to buy a much less expensive tool with replaceable dies. Not quite as convenient & easy to use but much more cost effective! Then again I wasn't going to be spending hours putting coax connectors on cables. A broadcast plant had many hundreds and probably thousands of uhf coax connectors to deal with and a lot of experience in all conditions from fully climate controlled (tape rooms) to harsh outdoors on ENG or SNG truck masts going 60 or 70 MPH in rain, sleet and snow. In fact when we replaced a 1,000' tower. We cut off the coax seal on connectors that were maybe 20 or 30 years old - the connectors were bright and shinny underneath! Proper installation of the UHF connector is to make sure it is made properly, and then properly mated by rotating the coax until the tiny indentations on the female are found and mated with the male. Then tighten it hand tight. If not indoors then seal the connection. 73 George AI4VZ -----Original Message----- From: Mike Harris via Elecraft I must say that over many years and without any ill effect I've never bought into this idea of Gorilering up a PL259 with pliers beyond finger tight.

Probably the least unbalanced of "balanced" antenna systems that ever existed were the HF point-to-point rhombics and V-beams at the RCA, Mackay, and Marconi shore stations in the first 60 or so years of the 20th century.? Despite very precise engineering to make them balanced, the RF currents in each side of the open feeders were never exactly the same. As a teenage ham, I tended to think in absolutes and exactitudes. If my Heath MM-1 multimeter said the screen voltage was 176.5 V, I believed it was, exactly, and if the spec said 177.5 V, I needed to do something to "fix" it.? If the ARRL Handbook said the two halves of my 40 meter dipole needed to be exactly 32.9114 feet, I believed that the antenna would not work if I didn't assure my dipole was exactly 32.9114 on each side.? As I grew older, both in age and ham longevity, I realized my Elmer was right when reminded me on multiple occasions, "We're amateurs.? Most often, 'close' is good enough." Seems like many today are convinced that 32.9114 ft will work but 32.9000 ft won't. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 7/16/2020 1:00 PM, Jim Brown wrote: > On 7/16/2020 1:14 AM, Victor Rosenthal 4X6GP wrote: >> If the antenna is well-balanced and fed via a true balanced antenna >> tuner (preferably link-coupled) then there shouldn't be a problem >> with common mode currents. > > Few ham antennas are perfectly balanced -- they are often unbalanced > by their surroundings.

The other is the use of off-brand connectors that do not fit well. The other is that some connectors do not engage the protruding 'tabs' on the PL-259 do not seat properly with the indentations on the SO-239. Those are the ones for which "finger-tight" is not good enough. I agree that 1/4 turn is too much - if you can turn it that much, it was not properly mated, remove and start again. Just a slight touch of the pliers will make it certain the connector is tight. 73, Don W3FPR On 7/16/2020 5:25 PM, Gmail - George wrote: > Years ago in a land far-far away all video coax connectors in Broadcast > Television were UHF (PL259). > We only tightened them hand (finger) tight.

It?s easy to ignore this step because many hams think they mate automatically as the PL-259 penetrates the SO-239. They sometimes don?t.

One thing we noticed that was common to all the models in both the big box stores was a taped on paper sign reading BACK ORDERED. We had little success trying to get one from either big box website, but did finally get an order placed for delivery a month ago. Grandmother got the new dryer about two weeks ago. Delay after delay. I think we should realize that a lot of changes have to be made for a company to comply with the guidelines and ensure employee safety: workspace spittle shields, ingress body temperature checks, PPE such as masks and gloves, and the 20 questions that should be asked every Monday regarding what employees did over the weekend. Not only does Elecraft want to ship products and complete repairs in a timely manner, they also want to avoid jeopardizing employee health. We too should want Elecraft to meet these objectives, particularly the latter. I continue to see the video of some woman ranting about her right to not wear a mask. She is evidently completely clueless about how SARS-CoV-2 spreads. So, you can mock me for wearing a mask, but I hope you won?t have to mourn me because someone else did not wear theirs.

I agree completely, but there's a "catch". Traveling-wave antennas, such as Rhombics, or Beverages, or leaky transmission lines, are, technically, non-resonant. However, they can each present a 50 ohm feedpoint impedance that is purely resistive, and produce a 1:1 VSWR as a result. ;-) So, whether an antenna is resonant or non-resonant isn't the issue. The issue is whether or not a load impedance contains a reactive component. If it DOES, then it can never produce a 1:1 VSWR. 73 de John, KD2BD From k6dgw at foothill.net Thu Jul 16 18:58:54 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 16 Jul 2020 15:58:54 -0700 Subject: [Elecraft] K4 in production In-Reply-To: References: Message-ID: <6924711d-e6cd-9485-58f3-40ef8ce9661e@foothill.net> Yes, I too have a math degree and the mean population density of California is ~98/sq km and yes, all the people in CA could stand well more than 1 m apart and no one would need scuba tanks or find themselves in Nevada [or Oregon or Arizona or Baja California].?

He came home with 50 feet of RG58C/u which has a stranded center conductor and a characteristic Z of 53?. I politely asked him to return it since it wasn't the correct impedance. The counter clerk tried to explain that it was "better" because of the more flexible center and the very slight difference in characteristic impedance wouldn't make ANY difference in performance, but he insisted and came away with a new piece of RG-58/u. I think l I used it to string up a 15M dipole between our two chimneys. Never DID get that %$#@ Globe Chief to work on 15 though. For some reason, it had more output on 14 MHz than 21 even when I had the bandswitch on 15M My entire Novice career was spent on 40M CW and 2M AM back when Novices had 145 to 147 MHz. 73, k3ICH (ex KN3ICH in1959) -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Fred Jensen Sent: Thursday, July 16, 2020 5:41 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA1500 in the IARU Contest Last weekend Indeed! Probably the least unbalanced of "balanced" antenna systems that ever existed were the HF point-to-point rhombics and V-beams at the RCA, Mackay, and Marconi shore stations in the first 60 or so years of the 20th century. Despite very precise engineering to make them balanced, the RF currents in each side of the open feeders were never exactly the same. As a teenage ham, I tended to think in absolutes and exactitudes. If my Heath MM-1 multimeter said the screen voltage was 176.5 V, I believed it was, exactly, and if the spec said 177.5 V, I needed to do something to "fix" it. If the ARRL Handbook said the two halves of my 40 meter dipole needed to be exactly 32.9114 feet, I believed that the antenna would not work if I didn't assure my dipole was exactly 32.9114 on each side. As I grew older, both in age and ham longevity, I realized my Elmer was right when reminded me on multiple occasions, "We're amateurs. Most often, 'close' is good enough." Seems like many today are convinced that 32.9114 ft will work but 32.9000 ft won't. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County From zk2boy at hotmail.com Thu Jul 16 20:09:06 2020 From: zk2boy at hotmail.com (zk2boy) Date: Thu, 16 Jul 2020 21:09:06 -0300 Subject: [Elecraft] K2 15K Resistor In-Reply-To: References: Message-ID: Barry, There was one 15K resistor in the two RF bags.

Edmond Bruce's rhombic antenna patent was filed in 1931. www.aktuellum.com/mobile/circuits/antenna-patent ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1685103 The heyday for the rhombic ran from the 1930s through the 1970s with the advent of satellite communications. The 200 foot tower for my 40 meter stacked 3 element Yagis came from a decommissioned Laport Rhombic installed at the NSS receive site in Cheltenham MD. We removed it in 1985, but it hadn't been used for years. 73 Frank W3 ----- Original Message ----- From: "Fred Jensen" To: elecraft at mailman.qth.net Sent: Thursday, July 16, 2020 9:41:21 PM Subject: Re: [Elecraft] KPA1500 in the IARU Contest Last weekend Indeed! Probably the least unbalanced of "balanced" antenna systems that ever existed were the HF point-to-point rhombics and V-beams at the RCA, Mackay, and Marconi shore stations in the first 60 or so years of the 20th century. Despite very precise engineering to make them balanced, the RF currents in each side of the open feeders were never exactly the same. As a teenage ham, I tended to think in absolutes and exactitudes. If my Heath MM-1 multimeter said the screen voltage was 176.5 V, I believed it was, exactly, and if the spec said 177.5 V, I needed to do something to "fix" it. If the ARRL Handbook said the two halves of my 40 meter dipole needed to be exactly 32.9114 feet, I believed that the antenna would not work if I didn't assure my dipole was exactly 32.9114 on each side. As I grew older, both in age and ham longevity, I realized my Elmer was right when reminded me on multiple occasions, "We're amateurs. Most often, 'close' is good enough." Seems like many today are convinced that 32.9114 ft will work but 32.9000 ft won't. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 7/16/2020 1:00 PM, Jim Brown wrote: > On 7/16/2020 1:14 AM, Victor Rosenthal 4X6GP wrote: >> If the antenna is well-balanced and fed via a true balanced antenna >> tuner (preferably link-coupled) then there shouldn't be a problem >> with common mode currents. > > Few ham antennas are perfectly balanced -- they are often unbalanced > by their surroundings.

We solved the poorly > made connectors by going to crimp style of connectors. There is a very large difference in signal to noise ratios and operating power levels between an analog video production facility and a ham station. 30-40 dB SNR is great for that broadcast plant, and unless it's colocated with the transmitter, far less exposure to RF than a ham station running legal limit. In our ham stations, we may need 100 dB or more rejection of RF; the 60 dB difference translates to a 1,000,000:1 power ratio and a 1,000:1 ration of voltage or current. In addition to my own station, where I do a lot of serious contesting, I've long been part of teams that do serious county expeditions, and I read a lot to try to learn as much as possible from others who do it more, and at a higher level. Two admonitions from these folks who do it in the field stand out. 1) If anything is flaky in the station, ALWAYS suspect a bad piece of coax or badly terminated connector. 2) Always make sure that all connectors are wrench tight. And I'll add my own -- NEVER use junk connectors or adapters anywhere in your station. For RF connectors, that means Amphenol (83-1SP w/no suffix for UHF) or used MIL-spec. For audio, that means Neutrik or Switchraft. 73, Jim K9YC From norrislawfirm2 at gmail.com Thu Jul 16 22:47:48 2020 From: norrislawfirm2 at gmail.com (Eric Norris) Date: Thu, 16 Jul 2020 19:47:48 -0700 Subject: [Elecraft] K-POD Coiled Cord?

This fluid state appears while a specific completion date and time was never assured of, & in subsequent conversations with advance purchasers. As there was never a promised date, there is a Pandemic where over 100,000 people in the USA alone have already died, Manufacturing globally has taken a real hit, transportation has taken a major blow. I had a USPS 2 day package shipped from Michigan on Sat 11 and it is nor the 16th & tracking shows it just left Michigan on route to CT. It may be here on Saturday. That'll be a 6 day delivery with a 2 day promise. That same kind of delay is happening to the construction of the K4 and any new components are also affected in this way. There is no other choice and I want it And I want It Now pressure doesn't do anything but waste everyone's time. It has zero rate on accelerating production and if anything, detracts from the focus from the principals. All this takes me back to the bemusement I get when reading such comments. Do they really believe in this arena it will move anything along faster, and if the company indeed did rush to complete while not having sufficient components in, on time, that it would behove the production run in any way whatsoever? Good friends, chill, this is an unprecedented time and Elecraft is moving along in the best way to give the best product they can do. We'll have our little beauties when they're vetted and competent.

No, it's FAR more complex than that. Horizontal antennas see the reflection from the earth as a parasitic element, which adds a complex impedance to the equivalent circuit. The reflection, and thus the parasitic impedance, will depend on height above ground, the skin depth of the earth, and the electrical qualities of the soil. The ON4UN book, "Low Band DXing," includes a set of very interesting plots of antenna impedance as a function of height and soil quality. In general, the feedpoint Z of low dipoles oscillates as height varies, with the average near 50 ohms, while high dipoles oscillate around 70-80 ohms. It's easy to see this in the very simple NEC model of a center-fed dipole (the model is a wire with a generator in the center of it) by varying the height and the soil parameters. My dipoles for 40 and 80M are up about 125 ft in tall trees, and I have lousy soil. The model predicts Z at resonance in the range of 85 ohms, and I've measured 88 ohms. I feed them with RG11. Some years ago, I was planning antennas for a CQP county expedition in a spot that has scrub trees (max rigging height ~40 ft) and lousy soil, but is on a small knoll, so the takeoff angle is great. NEC predicted 75 ohms for one of them and 50 ohms for the other, so we carried RG8 for one and RG11 for the other. When we measured them, they turned out as the NEC model predicted. There are computational tools and instrumentation that one can learn a lot from if we use them to study stuff like this. NEC is one of them. 73, Jim K9YC From k2vco.vic at gmail.com Fri Jul 17 03:04:55 2020 From: k2vco.vic at gmail.com (Victor Rosenthal 4X6GP) Date: Fri, 17 Jul 2020 10:04:55 +0300 Subject: [Elecraft] KPA1500 in the IARU Contest Last weekend In-Reply-To: <639b78c5-c34e-8ecc-3673-1e5ab7391cae@foothill.net> References: <20200715113656.Horde.Ez06_xF3RqQyKcmfjZAeHaW@www11.qth.com> <1245664018.350867.1594838808426@mail2.virginmedia.com> <81781e8b-5612-73c1-f2e5-deb484b2febc@audiosystemsgroup.com> <2064574118.350451.1594845405663@mail2.virginmedia.com> <77c02347-9128-d177-c3d8-171d02c8c36b@audiosystemsgroup.com> <601787d0-e7a2-66cd-be2a-95d1711f5dd9@gmail.com> <911a9163-7dba-7a4b-68d8-102691161f0c@audiosystemsgroup.com> <639b78c5-c34e-8ecc-3673-1e5ab7391cae@foothill.net> Message-ID: <3c170d2e-1a1c-5db1-441a-0e313d37e576@gmail.com> I took great care in the construction of my rotary dipole and feed system to make it as balanced as possible. I made a clamp-on device from a split ferrite bead that I can use to measure the relative currents in the open line conductors, and they are very close. There is one direction in which there is measurable unbalance due to a nearby object, but unfortunately this is also the direction of my major source of noise, another building 100m away, so it's not possible to tell whether the unbalance contributes to the noise or not. Someone else said that balanced lines don't reject common mode noise. It's true that common mode noise currents can flow on the feedline, but they are rejected by the balanced link-coupled tuner at the transmitter end. I unfortunately don't have a choked coax-fed dipole to compare it to, but it is much quieter than the previous antenna, a coax-fed multiband vertical. And it is also a far better transmitting antenna. Let's hear it for 1930s technology! 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

Using ALC to control the drive will also introduce distortion. The only disadvantage of the per-band power setting is that if you want to run more than 60w when you operate barefoot, you have to remember to turn it back down when you want to use the amp. This is automatic with the KPA500 and 1500, but not with a non-Elecraft amp. I once created a macro which would set the power and activate one of the K3's digital outputs, which I used to control a relay that switched an amp in line. That worked. But now I just run 60 or 70w when I'm barefoot. There isn't that much difference from the full 100w. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

I make sure that the cable is not free to flap around and "Plasticene" does the job. If there's only two "teeth" on the PL259 connector then I frequently file them off and ignore the slight plating loss. I cover the threads with a mixture of zinc and Vaseline anyway. This is a concoction that we used to use at work (in a loosely aerospace related company) to facilitate riveted ground points on galley structures prior to Meggar tests, but that process fell into disuse. It came about because the guys were using heatsink compound until I arrived and pointed out their error! I still use the zinc and Vaseline on threads though because it lubricates and the zinc helps conductivity a little, but my stock has all but gone.

Message-ID: I've upgraded both of my K3 while ago with all parts available to make them K3S (more or less). My main K3 shows some weird behavior with the audio level comparing left and right stereo channel (KIO3B). I'm feeding this K3 mainly with 144 transverter signals from XPol yagis (moonbounce system) with the Hpol signals on the main RX and Vpol signals at the second RX (AUX). Main RX is left channel on the USB soundcard while SUB RX is the right channel (Windows 10, MIC input). Even when on both RX (main and sub) the HF signal level is exactly the same (i.e. -120dBm from a HP8664A signal generator, split by 3-dB for main and sub) the left audio channel (main RX) shows exactly 6dB less compared to the right audio channel (sub RX) at USB audio out. On the IF-side (28 MHz) signal strength is exactly the same level, measured with my Siglent Spec Analyzer. Just .34dB difference main/sub. This doesn't happen on my 2nd K3 which is almost exactly the same inside like #1 except it's a 10W version. Any idea?

Yes, for normal operation, set your radio at a lower power to drive the amp to the desired level, which does NOT activate the ALC. However, if you do something "un-smart", the ALC will hopefully protect the amp's input. Just to make this plain, do NOT run your 100/200 watt radio at max output and depend on the ALC connection to cut it back. 73, Charlie k3ICH From kb1tcd at gmail.com Fri Jul 17 13:09:28 2020 From: kb1tcd at gmail.com (JP Douglas) Date: Fri, 17 Jul 2020 13:09:28 -0400 Subject: [Elecraft] =?utf-8?q?Joke_status_wasn=27t_wasted_on_me_?= =?utf-8?b?8J+Ygg==?= In-Reply-To: References: <6924711d-e6cd-9485-58f3-40ef8ce9661e@foothill.net> Message-ID: What does this have to do with Elecraft???

I have a dual-band 80-40m inverted-V with apex at 40-foot and 80m wire tail at 20-foot. The separate 40m wire is spaced 6-inches from the 80m wire with wooden dowels. I found by trial-n-error that one must tune the lowest frequency wires, first. I did that using an antenna analyzer. Then the 40m wires. Turns out (probably due to coupling) that the 40m antenna is narrow bw (50-KHz at best) whereas I get good SWR from 3650-4000 KHz. The purist will say that's not resonant but the transmitter is happy. I can run bypass on 3800-4000 KHz with my KXPA100/KXAT100 but must tune using the atu on 40m. For working around Alaska (out to 800-miles) this "cloud burner" works well with 100w. I only use SSB on these bands. 3920 is the defacto calling/emcomm channel in AK. When we have an earthquake, 3920 lights up (as well as 14,292) for reporting from our remote areas. I live two miles from salt-water so tsunami watch is common after a "big one". 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From k6dgw at foothill.net Fri Jul 17 14:20:09 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 17 Jul 2020 11:20:09 -0700 Subject: [Elecraft] K-POD Coiled Cord?

"All industries are equal, but some are more equal than others." I'm amazed at the folks that seem to think that ham radio equipment is even on the radar of anybody's 'essential' industry. What's even weirder, is that if you ask anyone to make up a list of 'essential' industries, it would look like no one else's list, ever. It seems that the industries that have the deepest pockets and the most to lose (all at the same time, it seems) are the only ones getting parts. All the small players are going begging. The major automotive OEMs (billions of dollars/yr in sales) have been back in production now for several weeks. Consider that the average vehicle these days has over 30K parts, and then try to figure out why small businesses like Elecraft can't get the parts they need to go back into production. It's not that the parts aren't available, it's that the parts went SOMEWHERE ELSE. Even the automotive OEM's have occasionally had to take a back seat to other manufacturers when it comes to electronics, especially the computer and cell phone guys. In the race to source microprocessor parts, there is a definite pecking order, based on volume and pricing and demand. If you sell a billion cell phones a year, guess who gets first pick? Sorry to bust everyone's bubble, but ham radio is really not that important, in the great industry wheel of things. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] K4 in production From: Rich NE1EE <73.de.ne1ee at gmail.com> Date: Fri, July 17, 2020 8:04 am To: elecraft at mailman.qth.net I'm sure that it varies by location and industry.

It is used by electricians to enhance aluminum to aluminum and aluminum to copper or brass electrical connections. Each of these products appears to be a mixture of a silicone based grease and powdered zinc metal. I have used such, between sections, when assembling an aluminum antenna. Before assembly, I apply the grease and use emery cloth to shine up the outer part of the inner tubing. I apply the grease to a wire brush made for plumbing and use that to clean the inside of the outer tubing. Aluminum is a very chemically reactive metal. It quickly forms an oxide that protects the surface from further reaction. Unfortunately, aluminum oxide is a pretty good insulator. By using the grease with the abrasion, the oxide is removed and the metal is protected from oxygen in the air during assembly. I find that this procedure prevents intermittent connections and makes future disassembly much easier. A friend had a multi band vertical antenna that was really flaky. The VSWR would change with the wind. We took his vertical apart and performed the antioxidant and abrasive treatment. His vertical worked reliably for years afterward. At one time, Mosley used to supply Penetrox with their beam antennas. A good move in my opinion. Gary, K0CX I cover the threads with a mixture of zinc and Vaseline anyway...I still use the zinc and Vaseline on threads though because it lubricates and the zinc helps conductivity a little, but my stock has all but gone.

The problem of believing you must have a resonant antenna arose with the use of coax cable began. High SWRs causes high system losses. Prior to the widespread use of coax, open wire was used and few antenna systems were really resonant, and nor were they reflecting a 1:1 SWR. Back then, no one cared as tubes were used and pi-net or swinging links were used to match to whatever was connected to the transmitter. In fact, I once visited a site that used rhombic antennas and Sterba curtains being fed by high power transmitters. The feed line were copper pipes about 1/4" in diameter and spaced about 4". The SWR, I was told, was 14:1. I asked if that was a problem of transferring energy to the system. The answer was no as the final output stage could match it and the system losses were low due to the type of feed line used. This was a lesson I learned 60 years ago and haven't forgotten it. The site was the RCA site the once stood on Montauck Point on Long Island, New York. One point that keeps getting forgotten is the conservation of energy concept. What that means is energy can only be changed and not lost. Typically that means transmitter energy would be changed to heat, but not lost. What is not changed to heat on the coax will make it to the antenna where it MUST be radiated and not lost.? Yhe practical application of this is use really good coax if you can't get to a 1:1-2:1 SWR, ot there about. Alternatively, use ladder line and a current balun. Elecraft tuners easily tune 10:1 SWR which contains system losses nicely. I have been doing this for a very long time and have achieved WAS, DXCC phone, DXCC CW, and DXCC digital, and, I'm 13 short on 80 of making 5BDXCC. 73, Barry K3NDM On 7/17/2020 1:47 PM, Edward R Cole wrote: > Interesting discussion: > > But most of us probably tune our antennas for best SWR at the desired > frequency. > > I have a dual-band 80-40m inverted-V with apex at 40-foot and 80m wire > tail at 20-foot.?

You're correct that open wire/ladder line transmission lines are not a panacea. But, in the average ham stations, open wire does overcome high losses with high SWR, or not so high SWR. What is needed is a look at the ARRL Antenna book for transmission line loss/100 ft. as a function of SWR. You see that on 10 meters running 10:1 SWR the total loss is around 1 db. And, as you go to the lower bands, losses become less. Typical 400 Ohm ladder line has a loss of 0.2 db at 10 MHz and 0.6 db at 100 MHz. Using these data and a little interpolation, I would use 0.4 db on 10 meters and a 10:1 SWR for this to be 0.8 db of additional loss for a total of about 1.2 db. Yes, I do use a balun and recommend them so add another 0.5 db. Add another 0.5 db for a good tuner and we end up with a total of 2.2 db. on 10 meters and less on 20 and it decomposes to an academic exercise on 40 and down. ??? Coax on 10 starts out with a higher loss/100 feet. I will use what I use here in K3NDM, Times LMR400. That represents 0.4 at 10 MHz. and 1.4 db at 100 MHz. That will yield about 1.2 db/100 ft on 10 meters. Add 0.25 db for a 2:1 SWR and 0.5 for tuner loss and you end up with about 1.95 at a 2:1 SWR. ??? Here coax wins IFF the SWR remains less than 2:1 which won't happen over the entire commonly used portion of the band. Using ladder line vice coax will contain losses over the entire band. This keeps things simple and the cost should be a lot less. ??? As to the RCA station with a 14:1 SWR, they used no balun nor tuner as we commonly know them today. The coupling to the final tube(s) were balanced and was capable of making the transformation from what the tube wanted and the reflected impedance at the transmitter end of the transmission line. Ergo, they had a very low loss if using 10 meters which they didn't. They typically used frequencies below 18 MHz and a slug of power.

But, in the average ham stations, open wire does overcome high losses with high SWR, or not so high SWR. What is needed is a look at the ARRL Antenna book for transmission line loss/100 ft. as a function of SWR. You see that on 10 meters running 10:1 SWR the total loss is around 1 db. And, as you go to the lower bands, losses become less. Typical 400 Ohm ladder line has a loss of 0.2 db at 10 MHz and 0.6 db at 100 MHz. Using these data and a little interpolation, I would use 0.4 db on 10 meters and a 10:1 SWR for this to be 0.8 db of additional loss for a total of about 1.2 db. Yes, I do use a balun and recommend them so add another 0.5 db. Add another 0.5 db for a good tuner and we end up with a total of 2.2 db. on 10 meters and less on 20 and it decomposes to an academic exercise on 40 and down. Coax on 10 starts out with a higher loss/100 feet. I will use what I use here in K3NDM, Times LMR400. That represents 0.4 at 10 MHz. and 1.4 db at 100 MHz. That will yield about 1.2 db/100 ft on 10 meters. Add 0.25 db for a 2:1 SWR and 0.5 for tuner loss and you end up with about 1.95 at a 2:1 SWR. Here coax wins IFF the SWR remains less than 2:1 which won't happen over the entire commonly used portion of the band. Using ladder line vice coax will contain losses over the entire band. This keeps things simple and the cost should be a lot less. As to the RCA station with a 14:1 SWR, they used no balun nor tuner as we commonly know them today. The coupling to the final tube(s) were balanced and was capable of making the transformation from what the tube wanted and the reflected impedance at the transmitter end of the transmission line. Ergo, they had a very low loss if using 10 meters which they didn't. They typically used frequencies below 18 MHz and a slug of power.

A low-loss (non-resistive) matching network connected directly at the feedpoint of an antenna will modify its resonant frequency. A matching network connected to the feedpoint of an antenna through 1 inch (25.4mm) of transmission line will also modify the resonant frequency of the antenna. A matching network connected through 1 meter of transmission line will also modify the resonant frequency of the antenna. A matching network connected through 10 meters of transmission line will also modify the resonant frequency of the antenna. And so on, and so forth... all the way back to the shack! ;-) Why? Because transmission lines obey reciprocity. As such they cannot (aside from the effects of losses) separate what's on their source end from what's on their load end. What you do to one end directly affects the other, and vice versa. Show me a transmission line that disobeys this property, and I'll show you a line that is either opened or shorted. So, yes, a non-resistive matching network in the shack will bring your antenna SYSTEM (antenna + transmission line) into resonance at your operating frequency. In the process, the resonant frequency of the antenna is modified, as well. 73 de John, KD2BD From k6dgw at foothill.net Fri Jul 17 21:59:43 2020 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 17 Jul 2020 18:59:43 -0700 Subject: [Elecraft] Antenna tuners In-Reply-To: <1427258661.2942136.1595031251283@mail.yahoo.com> References: <1290759943.2931936.1595028875860.ref@mail.yahoo.com> <1290759943.2931936.1595028875860@mail.yahoo.com> <0ca90e1b-178c-1dd4-a02c-f2ee06709c5c@pinrod.com> <1427258661.2942136.1595031251283@mail.yahoo.com> Message-ID: No antenna has, at any time, anywhere in any of our lifetimes, been "tuned" by an "antenna tuner."?

That's a reasonable design, and if you have it high, I am not surprised it's working out well for you. Not every ham has the liberty to put up, grow, an antenna farm. I am in that position. I have only two antennas up, a 20 meter vertical dipole center fed which I operate 20-10 and feed it with ladder line and an 160 meter inverted L fed at the base with a remote tuner. I also have 5 elevated radials of varying length connected to the remote tuner , just because. Collectively, they work out well. It sometimes amazes me how some wire in a tree or two can be used to reach out and touch people. :-) I have never used a beam, but I do have a KPA500 and matching tuner which I use primarily for working 100% duty cycle digital modes. All of my contesting and DX work has been at the 100 Watt level, except Field Day when I run QRP. So, good going and luck. 73, Barry K3NDM On 7/17/2020 9:18 PM, Lyn Norstad wrote: > Barry - > > +1 > > I use nothing but 600 ohm OWL (True Ladder Line) and a short piece of coax connects to a 1:1 / 4:1 hybrid balun to allow matching the impedance perfectly with my KAT500. > > The antenna is a 360' center fed EDZ (design frequency of 3.5 MHz).

Unless the "tuner" is simply a broadband transformer, I might agree. But if the "tuner" is an LC network, like an adjustable L network, T network, Pi network, or a linked-coupled network, then I strongly disagree. A tuner is a 2-port network. A transmission line is also a 2-port network. Both networks obey reciprocity, meaning that what you do to one port of the network will have a direct influence on the opposite end. That being said, if an antenna exhibits a complex impedance at our frequency of interest, and that behavior can be corrected (brought to resonance) by the application of a particular value of reactance at the antenna's feedpoint, then that application of reactance can, for reasons of convenience, be made at the "shack end" of the transmission line. As such, the "tuner" in the shack is really "tuning" the antenna! There's no "magic" involved here -- just a simple understanding that things that are connected together actually behave like they're connected together. A transmission line doesn't isolate the shack from the antenna: It couples them together with the highest degree of efficiency we can muster/afford. Therefore, what happens at one end of a transmission line DIRECTLY affects the other, and vice versa. And so, properly applying an adjustable LC impedance matching network in the shack CAN (and often does) modify the resonant frequency of an antenna. 73 de John, KD2BD From ab7echo at gmail.com Fri Jul 17 23:33:03 2020 From: ab7echo at gmail.com (David Gilbert) Date: Fri, 17 Jul 2020 20:33:03 -0700 Subject: [Elecraft] Antenna tuners In-Reply-To: References: <1290759943.2931936.1595028875860.ref@mail.yahoo.com> <1290759943.2931936.1595028875860@mail.yahoo.com> <0ca90e1b-178c-1dd4-a02c-f2ee06709c5c@pinrod.com> <1427258661.2942136.1595031251283@mail.yahoo.com> Message-ID: <5901cc77-8872-3eac-3d7b-726556a825af@gmail.com> That's not in the least true, but those among us fixated on semantics continue to push that tired old myth. You could, for example, have an antenna with a feedpoint impedance of 50 - j40 ohms, and if you insert 40 ohms worth of inductance in series with the feedline at the feedpoint you will TUNE that antenna to resonance exactly the same as if you put an appropriate amount of reactance in the antenna itself or adjust its length ... all of which do exactly the same thing.? The antenna and it's feedline are inseparable as far as the overall network is concerned.? One is not independent of the other ... ever. Furthermore, the adjustment (i.e., "tuning") can be done at the shack end of the feedline with EXACTLY the same effect except for the transmission line transformation by the feedline, and of course its associated loss, since whatever is done at the shack end is reflected back to the antenna end. Yours is really a very tedious distinction that has no basis in actual physics or network theory. 73, Dave??

Thanks much for the reality check. And this summer I was told of the reverse beacon system, too, and I intend to see how that goes. I am just getting back into HF after many years hiatus due to jobs and moving, and started learning Morse code May 1. I intend to make my first contacts in the next week, stumbling as they may be ;-) Ya gotta get wet to go swimming! I am inclined to use the least power I need, and have been following that principle since the early days. I am making a small AFC feedback circuit for my TS-830 to be able to run its power back from the 100/220W it runs at full speed. (No, I am not loading it into a wheelbarrow and carting it into the hills ;-) I have a KX2 on order, and have been assembling parts for hiking trips: antenna, battery, key. I spend a lot of time outdoors, and figure I might as well add ham to that and enjoy the best of both worlds. I expect to be on the air on some mountain in NH by mid Aug, if the KX2 gets here by then. I fully understand the delays, so not impatient. ;-) Well, maybe a little... Found a YouTube on PSKreporter, so will check that out.

Our company is a USA company making discrete semiconductors. We are considered essential. So, we have been open throughout this pandemic. We have a packaging and test facility in the Philippines for some of our parts. Many component manufactures use Southeast Asia for packaging and testing. It is not just the Covid-19 that has had an immense effect on getting parts out of that region, but also the earthquakes, especially the one on 2/16. We have not seen any parts out of that region since the earthquake. In June Luzon opened up again. But you just don't start shipping parts right away. You first got to perform maintenance on the equipment, run quals and make a preproduction run. Even though our plant turned on in June, we don't expect any parts till the end of August, at the earliest. And don't forget about shipping. Even your Amazon Prime shipments may take longer these days. And that is especially apparent when importing parts. Things don't clear customs as quickly as they used to. So, even essential businesses are having trouble getting parts. We are all affected in some way with Covid-19. 72, N2TK, Tony -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jim Brown Sent: Thursday, July 16, 2020 4:18 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K4 in production On 7/16/2020 10:20 AM, Tox wrote: > The parts availability issue was supposed to have been resolved pre-covid.

I just wanted to give an update and post a question. I spoke with don last week was working on a few xv transverters. After speaking with don I found the control cable from the K-3 was not fully seating in the plug due to screws on the plug were not in there proper place. Fixed that and everything started to work. But I was having some stability problems with the XV144 model transverter Don once again stated to check the attachment of the power module that it is grounded through the board where bolted to it. I also to some pics of the board. And for some reason when I looked at them I noticed all the flux I had not cleaned off the board. Never really noticed it much before even when looking at it through a large lighted magnifying glass. So I cleaned up the board. And the instructions have you putting a small washer between the board and the power module. So as he stated the is where the grounding is happening and a bad ground would affect the stability. I replaced the washers with ones slightly larger to give a little more contact area. I believe it was Don that told me Elecraft sells or did sell A power module that the mounting area is thicker so there is no washers required there used as a spacer. But now everything is good. When I turn it on cold I will get about 22 watts out with 20 indicated. When I leave it on for a hour or so and everything is up to temp. I get about 20 watts out with 20 still indicated. So every thing seems to be good on the XV144 model. The question I have is on the XV50 At first it did not work I found Q5 to not be biasing. So I replaced it. This kit was partially put together by my father in law who purchased it before he passed. Then about ten years later I decided to finish it. But any how when I went to replace Q5 it looked like two of the legs may have been solder bridged and shorted. Maybe it as not bad. But I was already unsoldering it and had a new one so I just went ahead and replaced it. Then it would turn on after that. Then in the alignment I was not getting voltage at TP5 with the radio keyed. Re soldered some joint I found that looked suspect and once again cleaned all the flux from the board. I had voltage at TP5 for a short time. Then it went away upon investigating I realized I did not have that coax selected at the coax switch to go to the dummy. So I guess I transmitted into an open ended coax. Probably SWR way to high. And I probably burned up the power module. Looking from the front of the Xverter on the third lead toward the rear I have 13 VDC. On the second one back I get 4.4 VDC when keying. But never get any worth while at the fourth one back. All I get there is about .011 when keyed. So IT looks like the power module is getting power and is being keyed but I am not getting anything out of it. Just hoping for someone to tell me if this is correct and maybe if I can get this part from Elecraft or not.

I am using RUMlogNG on my MacBook Pro in contest mode which uses the CAT interface to send and receive RTTY. (It also uses CAT with CW.) If I try to chain output, e.g. press the function key to send my callsign several times, frequently the first parts of the chained output are dropped, as shown by the text shown in the VFO-B display. This does not occur on CW, so I think the CW to Data conversion may be involved. The command is defined in the programmer's Reference as: KY (CW or CW-to-DATA Keying from Text; If I chain by using a K3 memory and pressing the M1-4 button several times, the VFO-B display shows "CHAIN" and things appear to work correctly. I will admit, that while I can check what is being sent by listening to the monitor tones with CW, but I can't quite be sure about the RTTY.

However I experience that strong RF signals generate a poping audio noise on my KX3 sn 181X, when I rotate the VFO A knob. There is no distorting noise when rotating the VFO B knob, nor when N1MM+ or DXLab Commander is used to software control the VFO A. Hopefully someone can point to a way to eliminate the noise, which I guess must have something to do with the VFO A encoder. Wishing all a nice DX weekend 73 OZ7BQ, Hans Joergen (Joe).

All represent changes to the antenna itself, which would also include changing the height [e.g. cranking the tower up and down] and possibly cutting down nearby trees or metal buildings [:=).? Any change to the antenna itself or its near-field environment will affect the feed point complex impedance.? This would include adding traps, inductors, and capacitors to the antenna. When you're done flutzing with the antenna itself, you are stuck with whatever complex impedance you find at the feed point.? AM broadcast verticals are generally engineered for coverage near the edges of the market area, meeting non-interference FS requirements, and minimizing self-cancellation between the ground and sky wave.? Something in the vicinity of 195 degrees is generally optimal.? They are not usually resonant and there will be fixed matching network(s) at the base(s) ... AM broadcast stations aren't known to QSY much. I'm not familiar with the TurboTuner however many mechanical antenna adjusters operated by driving the phase angle between voltage and current to zero, that is effectively bringing the antenna into resonance so the feedline sees a resistive load. It's up to you to design the antenna so that resistive load matches the characteristic impedance of the feedline OR put a matching network between the feedline and the antenna feedpoint OR tolerate the SWR on the line and put the matching network in the shack.? Pick one. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 7/17/2020 9:44 PM, Rick NK7I wrote: > Save one; the screwdriver antenna on my truck is tuned (coil adjusted) by the TurboTuner attached to my radio until a match is found. > > And an argument could be made that a SteppIR controller performs a similar function. > > The rest are matching circuits to compensate for the disparity of input to output. ? > > 73, > Rick NK7I > > Email spiel Czech corruptions happen > >> On Jul 17, 2020, at 7:00 PM, Fred Jensen wrote: >> >> ?No antenna has, at any time, anywhere in any of our lifetimes, been "tuned" by an "antenna tuner."

Nothing gets "tuned." They come in a variety of flavors ... a pair of push-pull 807's with a resonant tank and a link feed to the antenna on open wire line is one.

I am using the internal K3 soundcard (ugraded my K3 with the K3S parts). The MITTY Option(O) has the proper Input and Output device selected (the internal K3 soundcard codecs). Asking MITTY to trasmit my callsign doesn't key the K3. The MITTY Options > Soundcard tab has the correct Reception and Transmission settings (the K3 codecs). I changed the Windows output device from the K3 internal codec to my headphones, and can hear MITTY transmit into my headphones. So I'm guessing this is a K3 setting, and I'm baffled. I have the K3 set to Data mode, with VOX on. The DATA MD setting is AFSK A, 45 BPS. The K3 CONFIG settings: RS-232 set to USB PTT-KEY set to OFF-OFF (I've tried all the settings) AFSK TX set to FIL OFF The MENU settings: AFX MD is DELAY 5 MIC SEL is set to LINE IN VOX GN is set to 000 Panel settings (lower left knob): The Mic gain is set to LINE 25. Vox delay set to 0.5. On the MENU settings, I ramped up the VOX GN from 000 to 050. Then when I transmitted with MITTY, it silenced the K3 during MITTY transmission, but no power generated. The red TX LED didn't light either. If anyone has suggestions, I'd appreciate it.

Maxwell was an engineer at RCA. He designed the antennas on several earth orbiting satellites and the antenna on the Lunar Rover. He explained this quite succinctly in his book Reflections (all three editions), by use of the conjugate matching theorem. As I recall, that chapter in his book (peer reviewed by the RCA engineering department) was called My Antenna Tuner Tunes My Antenna. Gary, K0CX But if the "tuner" is an LC network, like an adjustable L network, T network, Pi network, or a linked-coupled network, then I strongly disagree. A tuner is a 2-port network. A transmission line is also a 2-port network. Both networks obey reciprocity, meaning that what you do to one port of the network will have a direct influence on the opposite end. That being said, if an antenna exhibits a complex impedance at our frequency of interest, and that behavior can be corrected (brought to resonance) by the application of a particular value of reactance at the antenna's feedpoint, then that application of reactance can, for reasons of convenience, be made at the "shack end" of the transmission line. As such, the "tuner" in the shack is really "tuning" the antenna! John, KD2BD From w5sv.dave at gmail.com Sat Jul 18 16:00:57 2020 From: w5sv.dave at gmail.com (David F.

I note further when I turn on my KPA1500, my k3 tells me KPA500 (I guess I cannot update that?); when I switch the KPA1500 from STBY to OPER, it says OPERATE. So, why would it tell me AMP on power up (even with the amp disconnected and powered off)? And, is there a way to get it to report KPA1500 instead of KPA500?

Go to my website www.w3fpr.com and scroll the left column to the last article. That information will help you with setting the proper audio levels. At first, you may want to turn VOX off and use PTT via CAT command, or enter transmit with the XMIT button while adjusting the audio levels. After that is accomplished, you should be able to use VOX, although I think PTT via CAT command is better - each to his own, I know some disagree with me. BTW, you can make all those adjustments with the K3 in TX TEST mode so you do not have any RF output to worry about. 73, Don W3FPR On 7/18/2020 3:44 PM, Tyler Barnett via Elecraft wrote: > Dear Reflector gurus, > > Using my internal K3 soundcard, I can receive RTTY OK, but cannot transmit using MITTY. > > I am using the internal K3 soundcard (ugraded my K3 with the K3S parts). > The MITTY Option(O) has the proper Input and Output device selected (the internal K3 soundcard codecs). > Asking MITTY to trasmit my callsign doesn't key the K3. > The MITTY Options > Soundcard tab has the correct Reception and Transmission settings (the K3 codecs). > > I changed the Windows output device from the K3 internal codec to my headphones, and can hear MITTY transmit into my headphones. > So I'm guessing this is a K3 setting, and I'm baffled. > > I have the K3 set to Data mode, with VOX on. > The DATA MD setting is AFSK A, 45 BPS. > > The K3 CONFIG settings: > RS-232 set to USB > PTT-KEY set to OFF-OFF (I've tried all the settings) > AFSK TX set to FIL OFF > > The MENU settings: > AFX MD is DELAY 5 > MIC SEL is set to LINE IN > VOX GN is set to 000 > > Panel settings (lower left knob): > The Mic gain is set to LINE 25. > Vox delay set to 0.5. > > On the MENU settings, I ramped up the VOX GN from 000 to 050. > Then when I transmitted with MITTY, it silenced the K3 during MITTY transmission, but no power generated. > The red TX LED didn't light either. > From wes_n7ws at triconet.org Sat Jul 18 16:33:05 2020 From: wes_n7ws at triconet.org (Wes) Date: Sat, 18 Jul 2020 13:33:05 -0700 Subject: [Elecraft] Matching resonant antennas In-Reply-To: <013d01d65d34$cdd1f560$6975e020$@LNAINC.com> References: <034601d65ca1$4ed1a320$ec74e960$@LNAINC.com> <8BD199E8-CCBD-44AF-A379-134EC0A87C26@w2xj.net> <00b001d65d0c$3d319a60$b794cf20$@LNAINC.com> <013001d65d2e$aae03ef0$00a0bcd0$@LNAINC.com> <013d01d65d34$cdd1f560$6975e020$@LNAINC.com> Message-ID: Walt and I corresponded quite a bit at one time.?

In many cases, not necessarily yours, antenna performance seems to be based on countries worked, achieving WAS/DXCC, "It's way better than last year's antenna.", or "I worked Pitcarin Island last week." None of these "measures" are meaningful. I am a big proponent of having a half-wave dipole as one's "standard" antenna then using the RBN, WSPRLite, etc. to capture same-time data on the performance of each antenna over time. In other words, to say one's antenna works, is meaningless. To say it works well is also meaningless. To say it works better than...can have some value and perhaps even meaning. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From ghyoungman at gmail.com Sun Jul 19 00:21:11 2020 From: ghyoungman at gmail.com (Grant Youngman) Date: Sun, 19 Jul 2020 00:21:11 -0400 Subject: [Elecraft] KX3 Opposite Sideband Null -- Follow Up Message-ID: <09E829EF-9791-4A9A-B9AD-B2E22F16B3B0@gmail.com> Six weeks or so ago, I put up a couple of posts asking if anyone had had an issue with opposite sideband null on their KX3. I was having a problem getting a good null when FL3 was selected, although I had very deep nulls with FL2 or FL1. I wasn?t motivated to check because of a perceived problem. I had simply decided to rerun the null procedure on a ?just because? basis, for the same reason any radio I own ends up on the bench periodically for a checkup and alignment. I didn?t get any response from the list, so I presume this isn?t something most have rechecked. In any case, Elecraft support suggested my results indicated a defective KXFL3. After receiving and very carefully installing a new one, sure ?nuf. All is fine now. My subjective impression is that tuning around with narrow CW sounds ?cleaner? since I have a good null on all bands and all filter settings. I don?t really know if the original KXFL3 was DOA (although it was no doubt checked by Elecraft prior to shipment), if it suffered a random or infant failure, or if I was careless with the KXFL3 board while doing the initial kit build a few years ago. Could certainly and perhaps most likely have been the latter. Calibration is probably worth doing once in a while anyway. Components age and drift, and, no matter what, things just happen. And I did get excellent support from Elecraft while working through the problem.

My mistake was in assuming that my judgment, after 50 + years of doing this, would be accepted without laying out all the details, especially when combined with actual on-air performance (during times of less favorable propagation). So let me add to my prior post that I have spent a great deal of time with different "simple wire antennas" including inverted-V, sloper, end-fed, G5RV and yes ... several different "true" dipoles. Some single band, some resonant, some not, some with traps. And a few verticals with traps, base loading, center loading and top loading. And one three element tri-bander at about 55 feet. I am basing my opinion of this current EDZ on my experiences with those. That being said, I do not currently have any of those in place in order to facilitate an actual A/B test under exact same conditions. Nor do I plan to go to the cost or trouble to do so in order to satisfy the 5% of me that thinks it might be meaningful. 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of K8TE Sent: Saturday, July 18, 2020 9:57 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Matching resonant antennas Lyn, How do you measure your antenna's performance?

The problem went away after dismantling the K3 completely for another problem and the fan/temp problem has vanished. Maybe some loose connector had caused the problem. Monitoring the PA temp can be the first step to solve the problem. 73s Steef PA2A >> From: Tom Doligalski >> To: Elecraft Reflector >> Subject: [Elecraft] Cooling Fans >> >> I am the original owner of K3/100 #969, which still works great. >> >> I?ve noticed that recently the cooling fan comes on occasionally even >> if the radio is on, but not in use >>(volume down, no transmitting). >> FP temperature shows 41 C, and PA temperature is at 35 C >> >> This is not at objectionable at all, but made me wonder if this was a >> cause for concern. >> >> Any ideas? >> >> Tom W4KX From pa2a at xs4all.nl Sun Jul 19 15:34:16 2020 From: pa2a at xs4all.nl (Steef PA2A) Date: Sun, 19 Jul 2020 21:34:16 +0200 Subject: [Elecraft] K3 Issue In-Reply-To: References: Message-ID: <30843376c6f7f2aab7931f2b19943406@xs4all.nl> Ronnie, a few months ago I had the same problem when my K3 #1184 was on for about an hour. No RX, and no TX output. The KSYN3A synthesizer seemed to have lost contact with the rest of the K3 and it gave different error codes. The problem has finally been solved by disassembling the complete K3 and SUBRX with all of its TMP cables, and I suspect one of these cables caused the problem. An intermittent contact of the KREF3 reference oscillator could also be the cause. 73s Steef PA2A > From: Ronnie W5SUM > To: "Elecraft Reflector" > Subject: [Elecraft] K3 Issue > > Good Morning > > I purchased a used K3 a couple of weeks ago and received it last > thursday.

A properly seated TMP connector isn?t like to just pop out, even with the rigors of shipping. So it?s a better than even bet it wasn?t properly seated to begin with. If shipping actually did that to a seated TMP connector, you probably would have received a very non-rectangular radio with a forklift tine through the front panel :-) Grant NQ5T From n6kr at elecraft.com Sun Jul 19 16:52:14 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 19 Jul 2020 13:52:14 -0700 Subject: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution Message-ID: <67BF190D-8311-46E9-ABC0-C12CF3F5B567@elecraft.com> Those using a K4 transceiver with our KPA1500 amp will have the advantage of +/- 1 kHz resolution in VFO tracking. In many stations, this finer resolution will result in lower SWR and improved amplifier performance, especially on the lower bands. (The original resolution was +/- 8 kHz.) This is part an overall upgrade of our Auxbus control interface, taking advantage of the additional processing resources available in the K4. The revised protocol allows for more robust RFI rejection, as well as future enhancements to amp/tuner control. At present only the KPA1500 supports radio type K4, but we hope to add this capability to the KPA500 and KAT500 in the near future. All amps and tuners will continue to support the original Auxbus protocol, remaining 100% compatible with our existing transceivers. 73, Wayne N6KR From mspmail2 at gmail.com Sun Jul 19 17:02:37 2020 From: mspmail2 at gmail.com (Mike Parkes) Date: Sun, 19 Jul 2020 21:02:37 +0000 Subject: [Elecraft] KX3 - Receive Opposite Sideband and I.F.

(My KX3 is a later serial number 9852 and according to the RX sideband null A8.doc, most of this nulling procedure was performed when the KXFL3 was installed by Elecraft, the only part not done(?) is the 2nd part of the RX SHFT=8.0 I.F.

So, I am trying to work through this (using an XG3 with its freqs set per the instructions to 1810, 3510, 5310, 7010, 10110, 14010, 18110, 21010, 24910, 28010, 50010) and I am at Page 5, Step 7: 7. Optimize RX SHFT=8.0 I.F. image gain and phase settings as follows: a. Set both the signal source and KX3 to the target band (starting with 160 m). Recall that *the VFO should be set 16 kHz higher than the signal source*. Make sure you?re in CW mode. (Note: You can change bands and modes from within the RXSBNUL menu entry.) *You should hear a strong signal,* and see an S-meter reading of between S9 and S9+30 dB. If not, adjust the preamp setting or the RF source level. What strong signal? With the KX3 iin CW mode, set to 16 KHz higher than the signal generator frequency, there is no signal at all heard! If I tune down on 160 meters to the XG3 freq at 1.810 KHz then it is very strong S9. What am I doing wrong here? Thanks for any help!

If it is sending KY*somes-string*;, then the messages are not going to be chained. If it is sending KYW *some-string*;, then the messages should be properly chained, perhaps with a very brief pause in between if 0x04 (Ctrl-D, ^D or EOT -- ASCII End of Transmission character) is appended at the very end of a each chained message, before the terminating semicolon. The "W" means "wait for message completion," as documented in the K3 Programming Manual. However, once a message sent via KYW starts, you will not be able to interrupt the transmission by pressing "Escape" or sending an "RX;" command. The RX; won't be processed until the message completes, which isn't very helpful. Maybe *that* will be addressed (somehow) in the K4. In sum, if you need chaining more than you need message interrupt capability, use KYW in your macros. If you need message interrupt capability more than you need chaining, use KY. If you need both, maybe you'll have to "wait" (sorry) to see if the K4 team comes up with some way to interrupt chained messages already in progress via a special "high priority" software command or key tap. 73, Bob, N6TV On Sat, Jul 18, 2020 at 7:39 AM Bill Frantz wrote: > I'm getting ready for NAQP RTTY today, and I am reminded of an > old bug using the KY CAT command to send RTTY text.

It has been to visit Don Wilhelm W3FPR twice before he retired from working on K2 radios. He upgraded the radio, gave it the latest versions, and made everything perfect. He also built the I/O serial style usb cable adapter plug and cable that attaches to the back. I bought a KUSB serial cable from Elecraft to use with the cable adapter plug. I have been considering selling this for a year or so. I use my KX2 and FTDX3000 D often, and hardly ever use the K2 anymore. I would rather sell it to somebody else so they could use it, than let it continue to sit here not being used. The serial number is 03965. The radio has the following options installed. KAF2 Audio Filter and Real-Time Clock KSB2 SSB Adapter KNB2 High Performance Noise Blanker K160M 160M and 2nd RX Port KIO2 RS-232 Interface and Aux I/0 KAT2 Automatic Antenna Tuner The KBT2 battery option was installed. I removed it for easier access when adding the other options, and it will be include though it is not installed. There is no KBT2 battery with he radio. There is no mic. The plug is wired for an Elecraft mic. The manual is included. I most recently swapped out the speaker and speaker cloth with new ones from Elecraft. Price is $735 firm. Shipping with insurance will be an additional $30.00 Payment will be a Postal Money Order or if in person, cash. I will ship the radio after the Postal Money Order clears the bank. If you are serious, and would like pictures or video, please email me.

What am I missing? Hi Andy, The improved resolution ensures that the correct bin is detected when you get within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz. This improves repeatability of selected LC values vs. VFO frequency, especially on 160 and 80 meters where it's most likely to matter. This also means that, in the future, we could use smaller bin width on some bands if desired. This could be helpful if you were using the ATU to fine-tune a very narrowband antenna such as a loop or electrically short vertical. 73, Wayne N6KR From n6kr at elecraft.com Mon Jul 20 00:28:47 2020 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 19 Jul 2020 21:28:47 -0700 Subject: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution In-Reply-To: References: <67BF190D-8311-46E9-ABC0-C12CF3F5B567@elecraft.com> Message-ID: <5DA60AEE-59BC-4E9B-B3DB-6E881AF3F9E9@elecraft.com> The K4 defaults to K3/K3S auxbus protocol, ensuring compatibility with a KPA500, KAT500, or KPA1500.

I can feed the amp exact frequency info via a Node Red Raspberry Pi. Right now using CAT over the KXUSB cable. Also it would be desirable to have CAT take priority over internal frequency counter on the amp. I've had the internal counter fail and the amp was in never never land when trying to transmit. I do have to say that after all the mods were done (current to when I sent in the RF deck) the amp has worked flawlessly. Many thousands of QSOs. Any way to track if there are additional mods to the amp that have been incorporated since last serviced? I would think if there were something major that existing owners would be notified. 73 Dave wo2x -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Wayne Burdick Sent: Monday, July 20, 2020 12:26 AM To: Andy Durbin Cc: Elecraft Reflector Subject: Re: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution Andy (K3WYC) wrote: > I still don't see the advantage of AUX bus giving the KPA1500 the TX frequency to 1 kHz resolution. What am I missing? Hi Andy, The improved resolution ensures that the correct bin is detected when you get within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz. This improves repeatability of selected LC values vs. VFO frequency, especially on 160 and 80 meters where it's most likely to matter. This also means that, in the future, we could use smaller bin width on some bands if desired. This could be helpful if you were using the ATU to fine-tune a very narrowband antenna such as a loop or electrically short vertical. 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 rocketnj at gmail.com From a.durbin at msn.com Mon Jul 20 08:00:28 2020 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 20 Jul 2020 12:00:28 +0000 Subject: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution In-Reply-To: References: , Message-ID: Hi Wayne, "The improved resolution ensures that the correct bin is detected when you get within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz." It has always been possible to provide the KAT500 and KPA1500 with TX frequency to 1 kHz resolution using the serial interface. KAT500: F (Frequency, GET and SET) GET format: F; SET/RESPONSE format: F nnnnn; where nnnnn is the approximate frequency of the last transmitted signal, in kHz. KPA1500: ^FR Frequency GET format: ^FR; RESPONSE/SET format: ^FRfffff; where fffff is the most recent frequency in kHz. However, both the KPA1500 and KAT500 tuners are designed to replace AUX or Serial provided frequency with RF detected frequency. This means that, even if the bin is selected accurately with serial or AUX frequency, the tuning solution is likely to change as soon as TX starts. This will only be prevented if RF detected frequency does not replace CAT or AUX provided frequency. This is a change I have been asking for almost as long as I have owned my KAT500. (Dick has my KAT500 defect/enhancement reports) Hopefully this change to K4 design will accelerate some of the fixes/improvements in both KAT500 and KPA1500 tuner firmware. 73, Andy, k3wyc From jd at ko8v.net Mon Jul 20 09:52:10 2020 From: jd at ko8v.net (Joe DeVincentis) Date: Mon, 20 Jul 2020 09:52:10 -0400 Subject: [Elecraft] Cooling Fans In-Reply-To: <79E5D0D0-3805-4EDF-A60F-853099A40E97@mac.com> References: <79E5D0D0-3805-4EDF-A60F-853099A40E97@mac.com> Message-ID: <14994CBE-25EE-41F5-AD94-44F91A39D5F0@ko8v.net> Personally, I wouldn't be concerned about the radio just yet. There's a couple of other variables to check first. How's the air flow around the radio? What's the ambient temp right around the radio (not the room, but right next to the radio)? Any thing sitting on top of the radio? Heat needs an easy escape. Any heat generating items near the radio (e.g. incandescent lights)? BTW, if the fan noise is objectionable, you can replace the fans with Noctua fans that have very similar characteristics and are quieter. I used Noctua NF-A6x25 FLX fans. The specs were almost identical and the fans are quieter. Here's a post regarding the fan replacement: http://elecraft.365791.n2.nabble.com/K3-Fan-Replacement-td7592075.html .

If you want to use TinyFSK (which has its own problems), connect a Mortty to the K4 ACC port, same as you would on a K3. If you don't want to solder your own DE-15 connector, or if your ACC port is already occupied, use a Y-BOX plus 3.5mm stereo to dual RCA cable to connect Mortty to K3 or K4. I have a few of both still in stock. It will take a few weeks to order more boards if there is sufficient demand. It could present multiple serial ports. one for CAT, one for FSK and one > for Keying. This is already in plan. The K4 provides two virtual serial ports via the USB cable (FTDI), one legacy 9-pin serial port, plus the 15-pin ACC port. Any of them may be used for FSK keying, PTT, and CW keying, using MMTTY or your logging software. This is keying via TXD, DTR, or RTS pins, with no external hardware required (unless using ACC pins). EXTFSK will be required on the virtual serial ports. The 9-pin legacy port will not require EXTFSK if your PC serial port or USB-to-Serial adapter doesn't require it (example: Edgeport/4). The FSK could emulate tinyFSK and the keyer could emulate the K1EL > keyers.

TinyFSK has a problem. Using it with MMTTY and a Mortty, try the "send RYRYRY... forever" macro while using TinyFSK.FSK. Hear the problem? It hesitates every 32 characters or so. So its timing is not as "perfect" as claimed, at least not with that configuration. While I despise the following phrase as a SW guy (specifically embedded > real time operating systems): Hey, it's just S/W. I can see this as very > doable in the K4 given what I know about the architecture to date.. Much > harder in the K3s. > As a software guy, you can appreciate that it is impossible to perfectly emulate someone else's code (or chip) if you have no access to the source code, and only work from the external API. Lots of devices have attempted to emulate the WinKey interface, but none of them are 100% compatible with the chip. This includes RemoteRig boxes, the YCCC SO2R Box, the Mortty, etc. None of them will pass the WKTEST program ( https://www.hamcrafters2.com/WKTESTX.html), last time I tried. The RemoteRig emulator works OK with N1MM+, but not with Win-Test or DXLog.net (unless you select a unique option). These programs all use the WinKey chip differently. They work fine with a real chip not with the emulators. The only devices that pass the WinKey 100% compatibility tests are devices that use a real WinKey chip inside, such as those provided by the microHAM devices. Retooling the K4 to put a real WinKey chip or Mortty hardware inside, or attempting emulation via firmware, could delay K4 shipment or distract from other higher priority issues. It could also raise the price a bit. I don't think anyone wants to see either. Finally, there's no reason for Elecraft to try to take sales opportunities away from the manufacturers of WinKey and Mortty devices, is there? 73, Bob, N6TV https://bit.ly/Y-BOX From dougfaunt at gmail.com Mon Jul 20 15:42:51 2020 From: dougfaunt at gmail.com (Doug Faunt N6TQS +1-510-717-1197) Date: Mon, 20 Jul 2020 12:42:51 -0700 Subject: [Elecraft] GCaptain discovers ham radio Message-ID: GCaptain, a website for professional mariners, has discovered ham radio: https://gcaptain.com/watch-the-resurgence-of-amateur-radio-a-silver-lining-of-covid-19/ From f8acf56 at gmail.com Mon Jul 20 15:50:25 2020 From: f8acf56 at gmail.com (Christophe aufacf) Date: Mon, 20 Jul 2020 21:50:25 +0200 Subject: [Elecraft] sidetone problem Message-ID: Good morning all , I repaired my K2 with Don recently the problem now I realized that I can handle in Cw but I no longer have at the same time the sound of the CW of course in emission the STL 030 menu, whatever the level, nothing changes, any idea? -- 73 , F8ACF56 From Webrider at nc.rr.com Mon Jul 20 16:35:04 2020 From: Webrider at nc.rr.com (Webrider at nc.rr.com) Date: Mon, 20 Jul 2020 16:35:04 -0400 Subject: [Elecraft] K2 For Sale again (other buyer fell through), #03965, $699 plus $36 shipping.

I removed it for easier access when adding the other options, and it will be include though it is not installed. There is no KBT2 battery with the radio. This radio is not the 100 watt version, it?s has the regular 15 watts. There is no mic though the plug is wired for an Elecraft mic. The manual is included. I most recently swapped out the speaker and speaker cloth with new ones from Elecraft. Price is $699 firm, plus $36 for insured shipping to the lower 48 states. Payment will be a Postal Money Order or if in person, cash. I will ship the radio after the Postal Money Order clears the bank.

I know TinyFSK has issues. But I was not intending that Elecraft copy the problems. I just wanted something similar to what TinyFSK does ( send a '[' to start transmit, send characters, send ']' to end). It could even be something different. Just something other than having to string together KY macros which doesn't seem to work well with software other than the K3 utility in conversation mode. As to the emulating of the winkeyer, I can't comment too much on it as I'm not a CW guy nor a user of a winkeyer product. If it is tough to get a good emulation on it, then it may not be a good candidate. I can live with that, others may have different opinion. The intent is to reduce the number of cables and boxes involved. One cable from the K4 to the computer and I get everything I need to do every digital mode that can be generated on a computer). In addition, I don't have to rely on the Windows machine to do any thing but send data characters to the machine at rates faster than the radio can put it out on the air (e.g send RTTY characters at 9600 baud for 45.45 output). That ensures, I'm not at the mercy of Windows stalling on a character send due its lack of being able to do anything with determinism. That's why I'm. not a fan of using windows keying a line to generate FSK. Too many non real time issues to have the guarantee. My goal is as perfect a(n) RTTY signal as I can get when I'm using that mode. I've been looking at the TinyFSK code to see if I can fix the issues i have with it - I've already found one bug in the software (500 doesn't fit in 8 bits). But that project got put on hold when K4 was announced with the hope I wasn't going to need it. But if I need it to get a near perfect 45.45 baud, I'll resurrect it and make it work. The little arduinos should be more than capable. If not with the original code, I'll put a better RTOS on it. As to taking business away from Mortty and Winkeyer, Is Elecraft wrong for taking business from the SDR guys because they put that capability in their radios? Is it wrong that I don't need to buy remote rig anymore? Again, no. That's two businesses that loose out because of the K4. And I was considering the purchase of both of those up until the K4 was announced. It's the nature of business - adapt or die. So far Elecraft has done well adapting. From what I see the K4 is a great example of adapting. They listen to their customers and to date they can see the handwriting on the wall when things change (touchscreen with knobs, SDR, Ethernet, remote capability all built in). As an example of listening, I can personally attest to it. When I chatted with Eric at Dayton about the K4, I gave him an idea for the machine. It was good enough that he stopped chatting, put a note in his phone and asked me not to patent it. I don't think he was kidding either. Maybe he was, but it did make me feel good. I just hope that idea made it into the radio.

If you want to use TinyFSK (which has its own problems), connect a Mortty to the K4 ACC port, same as you would on a K3. If you don't want to solder your own DE-15 connector, or if your ACC port is already occupied, use a Y-BOX plus 3.5mm stereo to dual RCA cable to connect Mortty to K3 or K4. I have a few of both still in stock.

The K4 provides two virtual serial ports via the USB cable (FTDI), one legacy 9-pin serial port, plus the 15-pin ACC port. Any of them may be used for FSK keying, PTT, and CW keying, using MMTTY or your logging software. This is keying via TXD, DTR, or RTS pins, with no external hardware required (unless using ACC pins). EXTFSK will be required on the virtual serial ports. The 9-pin legacy port will not require EXTFSK if your PC serial port or USB-to-Serial adapter doesn't require it (example: Edgeport/4). > > The FSK could emulate tinyFSK and the keyer could emulate the K1EL keyers.

Using it with MMTTY and a Mortty, try the "send RYRYRY... forever" macro while using TinyFSK.FSK. Hear the problem? It hesitates every 32 characters or so.

Lots of devices have attempted to emulate the WinKey interface, but none of them are 100% compatible with the chip. This includes RemoteRig boxes, the YCCC SO2R Box, the Mortty, etc. None of them will pass the WKTEST program (https://www.hamcrafters2.com/WKTESTX.html ), last time I tried. The RemoteRig emulator works OK with N1MM+, but not with Win-Test or DXLog.net (unless you select a unique option). These programs all use the WinKey chip differently. They work fine with a real chip not with the emulators. The only devices that pass the WinKey 100% compatibility tests are devices that use a real WinKey chip inside, such as those provided by the microHAM devices. > > Retooling the K4 to put a real WinKey chip or Mortty hardware inside, or attempting emulation via firmware, could delay K4 shipment or distract from other higher priority issues.

Since the KY command works for both CW and RTTY, I tried an experiment: I switched the mode using the K3's front panel from Data to CW and the problem did not occur. (I listened to the monitor output.) The UI for the program still showed RTTY, so I don't think it noticed my change and changed its behavior. There may be a problem handling the Control-D character in the K3. This character is ignored in CW, but it tells the K3 to stop sending RTTY when processed in RTTY. My guess is that RUMlogNG appends it to all KY sends. If another KY command's data is added to existing data in the buffer, The Control-D at the end of the first set of data may cause the second KY's data to lose the first character. What should happen if the last character in the buffer is a Control-D, and more data is added, is to remove the Control-D so the two sets of data are merged for transmission. Now I'm getting tempted to haul the KX3 up next to the K3 and decode what actually goes out over the air. Another interesting question is what happens if the first character of the second part of a chain is a "W"? BTW, I worked on similar software systems when writing the Tymnet interface for Tymshare's IBM/370 VM systems. 73 & GL Bill AE6JV On 7/19/20 at 6:50 PM, n6tv at arrl.net (Bob Wilson, N6TV) wrote: >Bill, > >Before it can be "fixed" in the K4, the logging software has to be fixed to >send the proper KY command.

The message quoted below was meant just for N6TV. [I have BCCed the author of RUMlogNG.] By way of explanation, After my last post on this thread, I got a telephone call from TV Bob, N5TV. We discussed the problem and narrowed it down quite a bit. We assume that RUMlogNG is sending RTTY data using the KY CAT command(*). We also assume that is isn't using using the W (wait) feature. We also assume that it is ending every string with EOT to quickly stop transmission. The UI of RUMlogNG is basically a standard contest logger. It has function keys, with basically the same definition of those in N1MM. You can also send free text by typing it into a window and using buttons to send and stop sending. What I observe: If I try to chain sends by pressing a function key before the entire previous function key message has been sent, frequently the first character of the chained message is dropped. My usual use case is to press F4 several times to send my call multiple times. I first noticed that the "A" in my call, AE6JV, was being dropped. When TV Bob and I discussed the issue, one of our theories was that the problem was only in the K3's logic that displayed the output of the send. We decided to set up a test using the Reverse Beacon Network (RBN) to discover what was actually being sent on the air. I set up F1 to be a bunch of CQs followed by DE, "CQ CQ CQ CQ CQ DE". I then started transmitting the CQ message by pressing F1 followed by 2 presses of F4. I observed the problem on the K3's display. My message to TV Bob was the results of looking at the RBM spots. I will note that while E6JV can be a valid call (from Niue, DXCC Entity #188), the RBN did not report any spots before I started my experiment. The spot generated from my experiment is the right time and frequency to be one of my transmissions. 73 Bill AE6JV On 7/20/20 at 11:09 PM, frantz at pwpconsult.com (Bill Frantz) wrote: >I got spotted 3 times with AE6JV and once with E6JV. ??!!?? > >Headed back to Rivermead after watching the comet.

You mentioned that you tried a ferrite snap-on on the USB cable. In order to really be effective, the USB cable would best be tightly wrapped around the sides of the snap-on in something of a serpentine or sequential fashion, not just randomly coiled up like a garden hose. I don?t know the specifics of how you did it, but I mention this in case you did the garden hose method originally?in that instance it would be a worthy exercise to rework your choke, wrapping it properly and seeing if that then makes a difference. Also, it?s not unheard of to need multiple snap-ons with multiple turns each to get enough impedance to choke out the unwanted signal. Especially if you can?t get 6 to 8 passes through the center of a single snap-on. Oh, and once you get the snap-on wound, it?s highly recommended to cinch down a zip tie around the circumference to ensure that both ends of the ferrite material inside are making good contact with each other. If there?s the slightest gap, the thing won?t work worth squat. Hope that helps, and that at least one of these suggestions you?ve been getting on the reflector solves your artifact issue. ;-) 73, David - N5DCH > On Jul 21, 2020, at 2:26 PM, Jim Brown wrote: > > On 7/21/2020 11:10 AM, Ignacy wrote: >> Perhaps the USB cable acts like an antenna. > > That often happens.

What am I missing? Hi Andy, The improved resolution ensures that the correct bin is detected when you get within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz. This improves repeatability of selected LC values vs. VFO frequency, especially on 160 and 80 meters where it's most likely to matter. This also means that, in the future, we could use smaller bin width on some bands if desired. This could be helpful if you were using the ATU to fine-tune a very narrowband antenna such as a loop or electrically short vertical. 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 lyn at lnainc.com From ghyoungman at gmail.com Tue Jul 21 18:03:10 2020 From: ghyoungman at gmail.com (Grant Youngman) Date: Tue, 21 Jul 2020 18:03:10 -0400 Subject: [Elecraft] PX3 signal artifact - still seeking a solution In-Reply-To: <09090D07-7B4C-4559-A8FC-42BE8E69C522@gmail.com> References: <1595355047181-0.post@n2.nabble.com> <36f5a1ac-a470-0754-8dbe-7fa162a380e5@audiosystemsgroup.com> <09090D07-7B4C-4559-A8FC-42BE8E69C522@gmail.com> Message-ID: <9D801A98-9877-458B-9799-D203371EC387@gmail.com> If the cable is shielded, and the garbage is on the PC's USB signal lines, an external ferrite won?t do any good.

Hi Grant, See my earlier post in this thread and the reference cited -- the problem is that the noise is NOT differential mode (inside the cable), it's common mode, and often on the shield, due to its improper termination inside the box. 73, Jim K9YC From rocketnj at gmail.com Tue Jul 21 19:46:05 2020 From: rocketnj at gmail.com (rocketnj at gmail.com) Date: Tue, 21 Jul 2020 19:46:05 -0400 Subject: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution In-Reply-To: <026c01d65fa7$808e60c0$81ab2240$@LNAINC.com> References: <026c01d65fa7$808e60c0$81ab2240$@LNAINC.com> Message-ID: <025b01d65fb9$19c3a910$4d4afb30$@gmail.com> I have seen this behavior using a non-Elecraft exciter (Kenwood) and KPA1500 amp on digital modes. In my case it was right after connecting the new radio and TX audio levels were too high, causing splattering. The freq counter in the amp wasn't happy. Lowered audio level to where there is no ALC deflection on the exciter and problem never happened again. Just a thought but check your ALC when on WinLink. You should not see any ALC indication.

I am, in fact, using an IC-7300 as exciter but ALC does not appear to be the problem. The 7300 > KPA500 > KAT500 chain has always been flawless for me until this new version of Vara was introduced, and I suspect it is indeed the new modulation scheme in Vara v4. I had a suggestion from Dick Dievendorff to try different FCCS values, and it seems that changing it from the default setting of 12 to a higher level, in this case 300, solves the problem without introducing other issues. I will continue to check this and report if I need to refine that setting. Vara 4 has already gone thru an update, so I suspect there may have been some issues found. 73 Lyn, W0LEN -----Original Message----- From: rocketnj at gmail.com [mailto:rocketnj at gmail.com] Sent: Tuesday, July 21, 2020 6:46 PM To: Lyn at LNAINC.com; 'Wayne Burdick'; 'Andy Durbin' Cc: 'Elecraft Reflector' Subject: RE: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution I have seen this behavior using a non-Elecraft exciter (Kenwood) and KPA1500 amp on digital modes. In my case it was right after connecting the new radio and TX audio levels were too high, causing splattering. The freq counter in the amp wasn't happy. Lowered audio level to where there is no ALC deflection on the exciter and problem never happened again. Just a thought but check your ALC when on WinLink. You should not see any ALC indication.

I am seeing issues with my KAT500 not holding a setting, but jumping to (and displaying) a frequency 200 - 300 KHz lower unpredictably during a Winlink Vara session. It always comes back to the correct frequency when the rig is transmitting, but has to go thru a short relay-clatter routine to get there. This is on 80, 40 and 30 meters (all I have tested so far). For example, if the dial frequency is at 7101 the tuner can't seem to decide whether to sit on 7104 or 7096. That doesn't seem to cause a problem as much as when it suddenly drops to 6874, 6864 or 6856. I am seeing similar behavior on 80m and 30m. I recently did a total reset and reloaded the firmware (v01.75). Any thoughts? Bin width?

I was getting pulsating noise on the signal sent to the KX3 from my MacBook Pro laptop. I tried all the suggestions including bonding the computer and putting ferrites on all signal and power leads with no improvement. I finally noticed that Elecraft KXUSB cable connected from PX3 to the laptop for rig control has an LED which blinks at a rate (almost exactly once per second) with corresponds to the noise heard. On the MacBook Pro I was using a port adapter which allows connecting a HDMI cable, a USB cable and an apple Lightning power cable to one of the 4 USB-C (Lightning) ports on the laptop. By simply moving the power cable from the adapter to a separate port the noise completely disappeared. Since you mention that your foul signal disappears when you disconnect the USB cable from your laptop I suspect you may be suffering the same problem. In my case, apparently when the LED pulses some of the power supply noise is coupled into the USB port and contaminates the signals. I was worried about transmit signals and did not see if any artifacts were showing on the PX during receive.

I am trying to get my amp to run cooler." Your question seems to imply that you believe increased dwell will make the KPA1500 run cooler. I wonder if you have any test data that supports that assumption. My testing of my KPA500 showed no significant advantage to pre-cool or increased dwell but I don't claim to have explored all possible operating conditions. I suspect that the most effective way to reduce temperature will be to lower the fan speed temperature set points. There is a trade-off between temperature and noise. The recent increase in the KPA1500 fan setpoints seems to suggest that Elecraft has chosen to reduce noise. Yes, there is a downside to very long fan dwell time. The fans will run longer and therefore wear out quicker. Why do it unless you have data that shows some advantage? "FANticipator" may help: - https://tinyurl.com/y4tw92zz.

After two years, I gave up. RemoteRig's internal keyer and COM port path when using N1MM are flat-out awful unless the Internet connection has extremely low latency and jitter. Low-error results cannot be accomplished from multiple remote sites while traveling. No amount of adjusting over a two year period would correct all the timing errors. I'm now using two WinkeyerUSB boxes and K1EL's Remote Software. One WKUSB box is installed at each end of the link. CW from paddles or keyboard is always perfect even with marginal internet connections. Setup is easy and having a WKUSB at the control point also gives me four physical memory buttons. The box is small and doesn't add much weight or space inside a remote equipment case. I dread the thought that the K4 includes an embedded variant of the RemoteRig -- as a means to accelerate product development. Although it's probably too late for Elecraft to consider a real, internal WK chip (and negotiate a deal with K1EL), that would have been my preferred method of generating CW from a remote location.

After two years, I gave up. RemoteRig's internal keyer and COM port path when using N1MM are flat-out awful unless the Internet connection has extremely low latency and jitter. Low-error results cannot be accomplished from multiple remote sites while traveling. No amount of adjusting over a two year period would correct all the timing errors. I'm now using two WinkeyerUSB boxes and K1EL's Remote Software. One WKUSB box is installed at each end of the link. CW from paddles or keyboard is always perfect even with marginal internet connections. Setup is easy and having a WKUSB at the control point also gives me four physical memory buttons. The box is small and doesn't add much weight or space inside a remote equipment case. I dread the thought that the K4 includes an embedded variant of the RemoteRig -- as a means to accelerate product development. Although it's probably too late for Elecraft to consider a real, internal WK chip (and negotiate a deal with K1EL), that would have been my preferred method of generating CW from a remote location.

Pure water is an insulator. Leakage becomes a problem when water becomes contaminated with conductive particles. This rarely occurs in closed loop systems that use distilled water when non-contaminating hoses, fittings, and heat exchangers are used. My 2KW LDMOS amp uses water cooling in such a closed system. My main amplifier at home is an Alpha PA-70V. The amp uses an openly-cooled vapor-phase system. A pint of distilled water separates 4KV of plate voltage and chassis ground. Water is in direct contact with the plate. In time, air particles do contaminate the water (usually in the form of algae) and the system must be purged and refilled at annual intervals. If leakage exceeds a predetermined amount, the amp faults and shuts down.

The key KPA1500 menu choices are: TECH MODE ENABLED RADIO TYPE ICOM SERIAL SPEED XCVR 19200 (or 9600 or 4800, but must match the CI-V speed of the IC-7300). I use 19200 here. XCVR SERIAL HOST DISABLED The key ICOM choices: Tap MENU, then "Set", then "Connectors", then "CI-V" Set CI-V Baud Rate to the same value as the KPA1500's SERIAL SPEED XCVR, probably 19200 Set CI-V Output (for ANT) to ON I have CI-V Transceive ON, but I'm not certain that's critical.

The same scheme can work with the KPA500. Placing the amplifier in "no poll" mode means the logging program must be responsible for polling the radio for frequency data, instead of the amplifier. No polling, no tracking (except by "RF sense"). If you have no need to control the KX3 or send CW by computer, and just want the amp. to poll and track the KX3, then building your own 3.5mm TRS crossover cable would be the most economical solution. Connection of the KIO2 connector of a K2 to the KPA1500 through the S-BOX is also possible with a standard RS-232 cable as long as the "PC" connector on the S-BOX is not used (which would connect too many lines to the KIO2 DE-9 connector). One of the S-BOX secondary DE-9F connectors (or builtin-in FTDI USB-to-Serial adapters) can be used instead to just connect the TXD, RXD, and Ground pins to the KIO2, leaving the others open. I don't know if the KIO2 AUXBUS line (pin 6) is compatible with the KPA1500 AUXBUS line (pin 2), but if so, this connection is also possible through the S-BOX's 15-pin connector and a 15-pin M/F cable, which I can also supply. I don't know if the ACC2 AUXBUS option on a KX3 is compatible with the KPA1500 AUXBUS. 73, Bob, N6TV https://bit.ly/S-BOX From n6tv at arrl.net Fri Jul 24 04:05:49 2020 From: n6tv at arrl.net (Bob Wilson, N6TV) Date: Fri, 24 Jul 2020 01:05:49 -0700 Subject: [Elecraft] P3 screen grab COM port conflict.

Times sure flies, eh? From the beginning, the output on 15M has been a little lower at maximum power setting than on the other 12 watt maximum output bands. Typically, I?d see 9-10 watts. No big deal. More recently, I?ve been trying FT8 operation. What I?ve observed is that for the first transmission on 15M using FT8, the output power starts out at 1 watt and gradually creeps up to perhaps 3 watts by the end of the transmission. The next transmission might get to 5 watts, and the third might get to the final value of what I set - 7 to 12 watts. (Yeah, I know about heating. That?s not the issue.) I think this is due to the way the ALC system works in the KX3. It doesn?t exhibit this behavior on CW. But, other bands are not nearly as bad. For example, on 80M the maximum output is attained on FT8 within a second or so of the first transmission. On 10M, it takes about three seconds. This start-up thing happens every time I change bands. That suggests that the ALC is slowly adjusting per band. Makes sense. In an attempt to correct this, I tried a TX GAIN calibration. It didn?t help. I asked the very helpful, and currently overwhelmed, support folks at Elecraft about this. Doug sent me the factory original config file for this KX3 to me, asking me to try loading it and checking, thinking that perhaps some value gotten corrupted somehow. That didn?t help, though it was a great idea. So, I started looking through the TX GAIN values that you can view when the TECH MD menu entry is set to ON. What I discovered was that the 15M value was and is significantly different than for the other bands. This was true for both the factory original calibration as well as a recent TX GAIN calibration. My guess, and it?s obviously a guess, is that the amount of ALC correction done on changing bands is somewhat related to the TX GAIN value. So, the very different TX GAIN value for 15M is taking much longer for the ALC to adjust to than on the other bands. My question of all of you is: What is the TX GAIN value for your KX3 on 15M? Perhaps what I?m observing is normal and just the way the radio works. But, maybe, there?s something amiss with the hardware. No way to tell without poking around inside with an oscilloscope, which I?d love to avoid if I could. Thanks very much for any help.

Same time. > To use diversity rx with the K4D, does the second antenna have to be connected to the RX ANT port, or a second ANT port, and do you need the internal ATU to get multiple ANT ports? First, just to clarify for those not familiar with diversity: this requires different antennas for the two receivers, which implies a K4D. (A basic K4 can still receive on any two bands simultaneously, but only with a shared antenna.) With no ATU installed, your choices for the second receiver's antenna would include RX ANT IN 1 and RX ANT IN 2. You could even use these two RX antenna jacks for the main and sub receivers, independent of the main antenna jack, which would still be used for transmit. With an ATU installed, you'd be able to specify any one of its three antennas as an RX antenna. This can then be assigned to either or both receivers. So this, too, is a diversity antenna option. > Can the internal ATU be assigned to an ANT port, or is it always assigned to ANT 1? The ATU has three antenna jacks (ANT 1/2/3). At a given time, one of these can be assigned to the LC network and thus be available for transmit (and optionally for either or both receivers). The two jacks not assigned to transmit are then available for possible use as receive antennas (see above). As an example, here's the control sequence you'd use to select ANT 1 for transmit, RX ANT 2 for the main receiver, and RX ANT 2 for the sub receiver. ANT (selects transmit antenna; tap once or twice to get to ANT1 icon) RX ANT > RX1 (main receiver) SUB ANT > RX2 (sub receiver) The default for both receivers is to use the same antenna as the transmitter. This is selected by: RX ANT > =TX SUB ANT > =TX Antenna configurations are stored per-band. You can optionally assign names (like "YAGI3", "LOOP", etc.) to antennas using an on-screen QWERTY keyboard. These names will then show up in place of the main RX/sub RX/TX antenna icons. 73, Wayne N6KR From donwilh at embarqmail.com Fri Jul 24 11:48:41 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 24 Jul 2020 11:48:41 -0400 Subject: [Elecraft] KX3 TX GAIN Values In-Reply-To: References: Message-ID: <69a29dc0-4faf-b5a2-46de-91a4713375f9@embarqmail.com> Clarke, That slow rise in power out is known as "power hunting", and is usually the result of not providing enough audio to the radio.

This hunting situation is, by far, most severe on 15M. On the other bands I barely notice the effect. The only obvious difference between the bands is the calibrated TX GAIN values shown in the Menu item available when TECH MODE is turned on.

So, it doesn?t seem likely to be an RF-getting-into-the-system problem. 73, Clarke K1JX > On Jul 24, 2020, at 11:48 AM, Don Wilhelm wrote: > > Clarke, > > That slow rise in power out is known as "power hunting", and is usually the result of not providing enough audio to the radio.

We called it "Vulcan Blood". It was a special Ethylene Glycol much like automotive anti-freeze but thicker and with lots of other goodies inside. It was an interesting MSDS sheet. An older RCA UHF TV Transmitter I remember "fondly" used distilled water. There was a resistance sensor on the circulation system that measured the resistance of the water. The meter pointer on the yellow part of the meter meant a long Friday overnight to Saturday morning session that week. Usually quarterly. And, don't even think of turning the rig off during cold winter nights! The heat exchanger had no heating element, and if you left the rig off for more than a couple of hours, the water would freeze and crack it open, which was a really bad thing to happen. No snow ever gathered in the vicinity of the heat exchanger exhaust duct. There could be two feet of snow on the driveway, but there was always a spot on the side of the building that was not only snow free, but often dry. Often, the icicles on the adjacent windows were legendary! Nobody ever thought of bypassing some of that heat into the building... Those were the days of cheap energy.

I don't think we used distilled water because it's resistance would increase over time from picking up ions from the metal. In our case it was cooling loops in a copper 37" electrode. I thought it was some kind of antifreeze or maybe an oil? And also isn't distilled water quite reactive? To many bourbons ago ?

After several weeks of troubleshooting, led by Don, W3FPR, of realigning bandpass filters, checking RF and DC voltages per the K2 manual, and finally confirming that the bias voltages were correct to the Q7 & Q8 finals, Don suggested ordering the K2PAKIT and replacing the finals. I did that this morning and that corrected the problem. I?m now getting over 100w out on all bands except 10m where I?m getting 94w! Don deserves all the credit and Don, I can?t thank you enough!

This has come up before, at least once. I think I?d try giving it a spritz of DeOxit and then working it a few times. One suggestion was to run about 1ma of dc current through it and switch it a few times to clean it. (I?m not sure I?d go that far, but it might work).

We have a K3S Setup with the K3S, panadpter, secondary knob, and a KPA1500. The amp has recently started something weird. When turned off, it will power cycle on for about a second, then turn off and repeat. The cooling fan comes on full speed, although nothing is warm. Turned on, it seems to act normally, although I didn?t press the issue much, just tuned into the antenna with low power. I did update to the latest firmwear, I know that part works. Looking at the fault log, I notice it mentions 10Volts, but I?m not certain how to interpret the rest of it. Possibly a fault in there somewhere. I do have a report into Elecraft, but I submitted it Friday afternoon, and a good chance there wasn?t anyone there at the time, and haven?t heard back yet.

I just completed my K2 build and the RX works great. Wish I would have done this years ago. One issue I noticed with the transmitter is that when I press the tune button, the output power will either be above or below the power control setting. I found this during the transmitter alignment phase of the build. If I have the output power set for 2 watts, I get 2.8 or 1.6. if I have the output set at 10 watts I get 9 or 5 watts. I am using an external watt meter and I verified that the voltage to the K2 is around 13.6 volts. This occurs on all bands by the way. I have checked RF voltages back to the control board at Q8 Valc and found that the output voltage , at this point, varies by a few tenths of a mv, thus changing the drive power down the line, changing the output power that changes the Valc output.....

That was done as an aid to those using manual antenna tuners. The K2 normally tries to keep the power steady at the requested power. 73, Don W3FPR On 7/26/2020 11:21 AM, barry halterman wrote: > Greetings. I just completed my K2 build and the RX works great.

Elevated radials must be tuned to be effective, but only 2 are needed.

You may need to remove the top cover if you don?t recall what filters are installed; frequently there is a paper sticker on the inside of the top cover that helps.

I have used a single radial ground plane and found this to be true (at 6' over dirt on 80M).? It favors a morning net 800 miles away, yet worked DX in any other direction easily (then I moved to a rotating dipole at 60' which beats it out).? That ground plane easily beat out a horizontal dipole I used before them all (fixed, in the 'wrong' angle because of tree location). Both the radiator and radial are tuned (equally), but the angle of difference from dipole to the traditional 90 deg ground plane will cause the resistance to vary (roughly 72 ohms as a dipole, dropping to ~50 ohms when at 90 degrees),? So if another angle is chosen (inverted Y), to match a 50 ohm feedline (to have a 1:1 SWR), the element lengths are adjusted equally until that match is made; altering the resonance of the wires (maximum transfer of energy).? And inverted Y antenna would be between that 50-72 ohm range, still acceptably low SWR to not mess with. Which again, is not a significant variance, so put it up, try it out and compare to other antennas.? Wire is cheap enough to play with and try things out. Modeling will demonstrate the pattern and 'take off' angles quite clearly; reality is often different because of local objects, ground resistance, height... Don't forget to add a common mode current choke at the feed. 73, Rick NK7I On 7/26/2020 11:57 AM, Don Wilhelm wrote: > Fred, > > That would be correct if they are oriented at 180 degrees from each > other so as to cancel the horizontal radiation.?

If you have an unsymmetrical radial arrangement, it's best to put a choke at the feedpoint to kill the common mode current. Almost in any case there will be some imbalance caused by nearby objects, so a choke is a good idea. Two radials is slightly less efficient than three or four, but not that much. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

One day all OK, the next day serious problems. Serial no.: 07818. It has ATU and 100 W PA installed, and also a P3 connected. Both K3 and P3 were earlier well calibrated. Supply: 14,5 VDC. Symptoms: - Rx seriously reduced sensitivity, only strong signals to be heard. - No Tx output. Tuning not successful, no SWR indicated (only the 3 hyphens). - Same on all bands. - All displays, controls and menus apparently working normal. - Mic-gain & ALC normal indication on SSB. All menu settings seem to be OK. Connected an XG3 and injected a -73 dBm signal. It showed up on all bands with signal level about -100 dBm, so around 30 dB attenuation. Connected a LP-100A and a 50 ohm dummy load. Whatever we tried, the LP-100A indicated zero power out on all bands. Same on both Ant1 and Ant2. Bypassed the ATU: no change. Set power to < 10 W, effectively bypassing the PA: no change. It is clearly something that is common for both Rx and Tx. It is independent of the selected band. Apparently not related to ATU or PA. So, it could be some relay problem, or related to the SWR bridge or LP-filters. Hope you can give some helpful ideas on how to proceed.

I have found on my own and a friends K3, both very low S/N around 300, that the KREF3 board has been the culprit for this exact problem. First check the all the TMP cables to and from the KREF3 board and the synths. If all look good you should examine the K3REF board. In both cases I have found 100nF (0.1uF) capacitors on this board to be essentially a low DC resistance. Look in particular at the 5 volt line. This supply affect IC6 the divide by 6 which provides both the second LO for the receivers and one input to the mixer for the TXIF1.

Here's where I would start: 1) Find spots on the RF board (top side) where you can measure the control voltages 7R and 7T. Verify that these change in opposition to each other, i.e. if 7R is high, 7T should be low and vice-versa, when changing from RX mode to TX mode and back. 2) Presuming that both voltages 7R and 7T behave properly in switching from RX to TX mode and back, I would measure the voltage on the drain of Q7, the MOSFET switch, when 7R is high. Assertion of 7R should pull the Q7 drain voltage low, which causes sufficient current to pass through both PIN diodes D26 and D27 to enable the RX signal to pass through, presuming there is not a problem with PIN diode D25. 3) It is possible that the Q7 drain voltage could be pulled low if only one of PIN diodes D26 or D27 functions properly and the other has failed open, so test (2) is not conclusive. 4) If you have a scope with a 10X probe, I would check for presence of RF on the anode of PIN diode D43 when in TX mode - any frequency on the VFO within the scope bandwidth should suffice. D43 must be forward-biased by the 7T voltage in order for RF drive to be coupled to the low power (10 Watt) PA assembly (Z2 on the block diagram). The fact that you have not been able to detect any transmitted power in TX mode whether the 100 watt PA is bypassed or not may indicate that the low power PA is not receiving drive from the mixer. The 7T voltage is supplied to the anode of D43 via the low power PA input connector, but it's unlikely that the simple path internal to the low power PA board is at fault, i.e. 7T is not reaching D43. I haven't had my K3 opened up for many years, nor have I experienced the problem you described, so I can't easily point out where to access the circuit points mentioned above. There is another set of PIN diode switches around the mixer, but I would start with those closest to the low power PA before going further back up the signal processing chain. 73, Mike, K8CN -- Sent from: http://elecraft.365791.n2.nabble.com/ From Mike.Carter at unh.edu Mon Jul 27 13:34:38 2020 From: Mike.Carter at unh.edu (Mike K8CN) Date: Mon, 27 Jul 2020 10:34:38 -0700 (MST) Subject: [Elecraft] Elecraft K3 problem In-Reply-To: <60265736-bbfd-39dc-91f8-91602ee9a832@gmail.com> References: <1595854256553-0.post@n2.nabble.com> <60265736-bbfd-39dc-91f8-91602ee9a832@gmail.com> Message-ID: <1595871278393-0.post@n2.nabble.com> I agree with Martin's simpler hypothesis. The sudden change of behavior in both TX and RX modes could well result from insufficient LO drive to either the 1st or 2nd mixers. Check that possibility before launching into detailed testing of the PIN diode T/R switch. It may be as simple as a loose or corroded TMP connector.

When the subRX is off, the only receiver you can hear is the main receiver. The main receiver's frequency is always controlled by VFO A, so with the subRX off you are always listening on the VFO A frequency (you can press and hold the REV button to swap VFOs temporarily and listen on the frequency that was in VFO B instead, but as soon as you release the REV button the VFOs are restored). When the subRX is on, you can hear both receivers simultaneously (depending on the L-MIX-R configuration setting). With the default A-B setting, the main RX is in the left channel and the subRX is in the right channel. The subRX's frequency is controlled by VFO B, except when the subRX is in Diversity mode, at which times the subRX's frequency is the VFO A frequency the same as the main RX.

Message-ID: Thanks to all who suggested a solution! Most of the hams on this list could easily work for the engineering or design departments at Elecraft. Sadly I am not one of them. I didn?t realize the mistake I was making when I did a EEinit on my K3S without a current config file. Fortunately Elecraft keeps config files on new radios or ones they repair. They emailed me the config file they saved when the rig was in for repair about a year ago. Thanks Rob! To those of you who don?t qualify for Elecraft employment. Make sure you save a current config file before doing anything as DRASTIC as an EERint.

Note that saved config files may be poisoned. Here's an email I meant to send to the list, but ended up just sending to NR4C: I had a problem with the mw Transmitter Gain calibration. It kept saying it read 2.07 mw when it should have been 1.00 mw. I went through a bunch of suggestions from support, which ended in EEINIT. That, and a manual reconfiguration of the radio to include the 100W amp, tuner, and USB computer interface let me run the transmitter gain calibration successfully from the utility. THANKS ELECRAFT SUPPORT. I then went back and reloaded old saved configurations. I had to go back about 5 of them, to 2017, to get one that would let me run the Transmitter Gain calibration without error. Doing the may have had some benefit in letting me being able to checkin to the 20M and 40M Elecraft SSB nets. That's hard to tell, but conditions today were pretty bad. 73 Bill AE6JV On 7/26/20 at 5:48 PM, nr4c at widomaker.com (Nr4c) wrote: >I don?t know why owners jump to a EEINIT to solve problems. >There are less distructive ways.

So FYI, this may or may not be the issue for the fellow who hears no signals on his K3. Note that I WAS seeing signals in NaP3, so at that point it was obvious that it was 'hearing' to a point, so the rest was somewhere and indeed was indeed within those TMP cables going into and out of the front boards. Thankfully it does not appear that I will have to resort to obtaining and installing the 'gold pins'. That would be WORK! Brian Pepperdine VE3VAW ________________________________ From: Brian Sent: July 10, 2019 12:36 AM To: elecraft at mailman.qth.net Subject: K3S IF signals seen in P3 and NaP3 but nothing heard A few weeks back I bought a used K3 upgraded to K3S in many ways, including a sub-receiver (which I doubt I will use). Anyhow.. about a week or so in I was in a situation where I could see IF signals on the P3 (and NaP3) but hear no signals. I contacted Elecraft service and they felt that if it persisted I might look at replacing the receiver board at the front (behind display panel) with gold pins (which could be ordered from DigiKey) but would require removal/replacement of the pins on the board. Not eager to do that if avoidable. Anyhow, by the time (day or so) Elecraft had consulted internally and responded the receiver was once again hearing and presenting signals. I left it at that, thinking well the radio WAS shipped etc. so maybe some settlement etc. Anyhow, earlier today (a month later ? ) the same thing happened. So before pulling the receiver board and re-setting it in the pin socket (hoping for a better connection) I looked at the other hardware connection there.. the two TMP plugs/sockets. So I took the two cables out with the TMP plugs on them and reset them twice. Behold, signals heard. I will let this be for now and if it does not repeat then leave it. I will let you all know if in the short/medium term the program stays away or returns. I did see ONE reference to this in the mail list archives, but the gold pins were mentioned there. Nothing re. the accessible and simpler TMP plugs. 73 Brian VE3VAW Toronto ON From donovanf at erols.com Tue Jul 28 17:28:49 2020 From: donovanf at erols.com (donovanf at erols.com) Date: Tue, 28 Jul 2020 17:28:49 -0400 (EDT) Subject: [Elecraft] Foot Switch Doesn't Work In-Reply-To: <1e28095d-d11d-fc9c-9d5a-a474c84e0035@kg6mzs.net> Message-ID: <1897414696.947711.1595971729959.JavaMail.root@starpower.net> Does the PTT in the microphone connector work? ----- Original Message ----- From: "kg6mzs" To: "Mike Harris" , elecraft at mailman.qth.net Sent: Tuesday, July 28, 2020 6:17:47 PM Subject: Re: [Elecraft] Foot Switch Doesn't Work Hi Mike, Thanks for the reply.

This is certainly a mysterious problem... If your microphone PTT works then the electronics in your K3 is working properly. As far as I know the microphone PTT and PTT jack on the rear of the K3 are connected together! In a pinch it wouldn't be difficult to build a simple cable that allows you to use the microphone PTT instead of the rear panel PTT jack. Heil microphone adapters already do that for you. 73 Frank W3LPL ----- Original Message ----- From: "kg6mzs" To: donovanf at erols.com, elecraft at mailman.qth.net Sent: Tuesday, July 28, 2020 10:32:38 PM Subject: Re: [Elecraft] Foot Switch Doesn't Work Yes, when connected to the front panel jack, the PTT in the Kenwood MC-60 works just fine.

K3 users are mostly familiar with the Tx Gate function that blocks audio below a threshold level to reduce background noise. Would it not be possible to recognise audio input above a certain pre-settable level and have that also block transmission. Normally a cough or sneeze is much louder than our normal speech (ignore this if you purchase larynx oil and practice for the appearance of P5 on a regular basis!).

Andrew G8BYB -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of kg6mzs Sent: 28 July 2020 17:11 Hello All, I've connected a Heil foot switch to to rear panel PTT In RCA jack and it doesn't key my K3. I searched the archives here and found that Don W3FPR had suggested testing the foot switch of another unfortunate, Dick K9OM, who suffered the same problem. This thread went unresolved, AFAICT. I've tested the Heil and it checks out. Any ideas as to why my foot switch will not key the K3?

Icom kinda gets a C grade on their 7610. So a radio that is going to compete with the likes of the Flex 6600 or 6700 is going to be a lot harder task. So Elecraft is probably working their keisters off to hit specs. The wait is frustrating, but it?s best if they get it done right. Note 2. I?ve come here because our club has a K3S setup. My personal radio is a Flex 6600.

To memory it was centered on 1500 Hz and about 1000-Hz wide. I went about looking for sources and disconnecting cables. With all antenna connections disconnected it was still there (oh bad). But I also wondered if a setting might have changed to produce it. Recently a question about setting up FT8 on the K3 had me going thru my settings so I rechecked them. Strangely clicking XFIL button cleared the display of the interfering signal. Hmm I said to myself, noting that button also controls DUAL PB. Could activating dual-PB in DATA-A mode produce this "effect"? Attempting to reproduce it with the XFIL/DUAL PB button was unsuccessful (which is OK). So this remains a mystery signal (apparently internal to the K3)?

Unlike N and BNC connectors, a PL-259 is dependent on proper engagement of its outer shell and interconnecting teeth to the mating SO-239 socket. Use a small pair of pliers to snug up -- not tighten -- the shell. Be careful not to crush the shell by exuberant use of force! It takes just a few seconds to assure a reliable connection. When engaging the center pin, be suspicious if the mating force is unusually low. 73 Frank W3LPL ----- Original Message ----- From: "Rick Robinson" Cc: Elecraft at mailman.qth.net Sent: Wednesday, July 29, 2020 4:34:52 PM Subject: Re: [Elecraft] Foot Switch Doesn't Work - Now Working Along the same line, use this thinking with your PL259/SO239 connectors.

BNC connectors have rather poor shielding performance caused by imperfect axial alignment and limited engagement pressure, both of which are easily demonstrated by a VNA, especially above 20 MHz. Both BNC and N connectors suffer from small center pin size and weak center pin engagement pressure, both of which affect reliability and power handling capability. Don't even consider installing the long obsolete multi-part BNC and N connectors with loose center pins requiring precise placement and axial orientation. Very many of these obsolete connectors are improperly installed by both hams and professionals. Modern BNC and N connectors with captive center pins are much more reliable and less subject to installation errors, although for some hams no job is so simple that it cannot be done wrong. 73 Frank W3LPL ----- Original Message ----- From: "Bill Frantz" To: elecraft at mailman.qth.net Sent: Wednesday, July 29, 2020 9:05:22 PM Subject: Re: [Elecraft] Reliable PL-259 UHF connector engagement As someone who is currently switching bands by going outside and replugging PL259s, I fully agree that other connectors, e.g. BNC would be nicer.

And there is. After conferring with Dave, WI6R and super helpful owner, there is already a resistor inside the CS6-ELK cable and two dip switches to control whether to provide bias to the mic element. Some blocking and filtering is also part of the circuit. The only thing I needed to do to the radio was to wire wrap from pin 6 to pin 5 on the K2 mic header to provide 5V at the mic jack pin 5 in the fashion of a Kenwood radio. Pin 6 was not connected at the mic jack. The CS6-ELK cable needs the provided bias to act like a Kenwood, not a K2. Then set the DIP switches and it works great. Now 1 cable and 1 mic element for both the K2 and K3! I've copied the circuit image inline, I just don't know if the reflector filters them out. If so, be happy to email it direct.

That's a standard tool in the cable industry for installing and removing "tamper-proof" F-connectors that have a shroud around them to prevent a subscriber's fingers from loosening them. It also works on non-"tamper-proof" connectors that are difficult to reach.

Does Comet have a tripod adapter? Elecraft has a tripod adapter for its portable antenna, the AX1. Will that adapter work for your use? If that adapter won't work, you can build an adapter. The standard tripod thread is 1/4" x 20. You should be able to get some nuts of that size and glue them to the necessary bracket to attach the adapter to your antenna. Or you can get a drill and tap and tap it yourself. There are many other choices and ways to proceed. As to the tripod, a lot depends on what you intend to do. If you are doing SOTA activations, you probably want a very light weight tripod for backpacking. If you can stand something heavier, there are photographic tripods in a bewildering array of models. I will also note that photographic light stands also have 1/4" x 20 threads and can be used as well. They aren't as useful on uneven ground as a tripod, but they go up higher. These things are available at a wide range of prices.

You make life easier for the matching unit by making your antenna non-resonant on bands you want to use. That way the unit does not have to cope with especially high voltages which are most likely to cause internal damage. Save your time, weight, money for other options.

Remove the line for other things, eg guys and turn it upside down. Peg the legs if it's windy. Make/buy a clamp for your antenna pole. I used this with a screwdriver antenna and a few radials on the ground; also with a fibreglass pole just taped on. They are quite heavy, so, not walking-portable but fits the boot/trunk of the car for a drive to your favourite spot. The legs are very long, so, cut to suit what you are doing if need be.

We all wish the best for Elecraft. It has been horrible for them and all of us living with this cloud. Free shipping or whatever I don't really care at this point. What I find fault with is the lack of communication. How hard would it be to have a regular update on the progress of the K4 box and other products? Even if there is no new news just say so. I am sorry but the communication has been far less than desirable. When I look at the Elecraft "stories" the last update on the K4 was May of 2020. The last update on in the newsletter was July 2020 with virtually nothing on the K4. Please...as you can see from the emails...just tell us what is going on. 99.9% of us are very understanding.

Free shipping while nice is not my concern but it would be reassuring for Elecraft to keep the many of us with large deposits better notified as to progress and delays. As I am in the EU, my shipment date will be longer by months than those of you in W land. We must have CE approval for shipment; this is essentially a EU wide check for safety purposes not too dissimilar to UL approval but perhaps more wide ranging. How much longer CE approval will take we have never been told that I can remember. My money stays with Elecraft. I am an Elecraft supporter and owner of many Elecraft products. When this K4 becomes available I may well order a second K4 plus second KPA 1500. It would sure be nice though to get a monthly update. It would also be interesting to have a more detailed specification sheet though I suppose this is being left to other labs to produce. Elecraft must though have these numbers. Maybe the good people in California want to make a big bang when the K4 does ship by blowing competition away. I am not about to ask for a refund of my deposit but I do pray that Elecraft is not another casualty of the Covid 19 virus. There is enough suffering and much more to come in commercial life. There are good people in the mother ship. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Richard Zalewski Sent: Friday 31 July 2020 16:26 To: Morgan Bailey Cc: Elecraft Reflector Subject: Re: [Elecraft] Free shipping My two cents.

The ?problem? is that Elecraft is not in position to provide their customer base with updates that will meet customer expectations regarding ?when will Elecraft start shipping product?? The moment that they make a public announcement, their feet will be held to the fire, both by their anxious-to-receive customers and themselves. So as Elecraft continues to work hard to get their product released, it doesn?t make sense for them to put out a public statement each week stating ?We don?t know yet when we?ll be shipping?. Such an effort to ?improve Communication? will simply further frustrate everyone > When I look at the Elecraft "stories" the last update on the K4 > was May of 2020. The last update on in the newsletter was July 2020 with > virtually nothing on the K4. Please...as you can see from the > emails...just tell us what is going on. 99.9% of us are very understanding. With all due respect, ?understanding? has its limits because we all want our stuff ?now?. And if they make an announcement and then modify it, what do you think the reaction will be? More frustration and angst. While customers are anxious to get what they ordered, Elecraft?s future is totally dependent upon releasing a quality product as soon as they are able to do so because of the significant investment they?ve made over the past couple of years to create the K4 and they need to gain revenue from the investment to maintain their future. I don?t know their financial position, but I consider them to be a ?small business? which means they don?t have unlimited resources. Customers are anxious for a product; Elecraft is anxious to maintain a business, support their employees, and maintain their reputation for quality products that exceed customer expectations. Who?s neck is more on the line with each passing day; the customer or Elecraft? So give them a break. The K4 will be released as soon as Elecraft believes that all of the ?ducks? (logistics, documentation, manufacturing, customer support, etc.) are lined up and ready to roll so that when their new product is delivered, it will more than meet everyone?s expectations. FWIW, I?m also a Flex customer and their reputation has been sadly soiled by the design/production issues they?ve had over the years. I ordered a Flex-6700 in 2012 when it was announced and received it in November 2013. However, SmartSDR was woefully inadequate and it wasn?t until May 2017 when version 2.0 was released that the software allowed the radio to do what they claimed would be possible (e.g. remote operation). In February 2018 I ordered the PGXL amplifier with accompanying tuner. I received the PGXL in May 2018 but I?m still waiting for the tuner, making the PGXL ?useless? for me to use with a EFHW that requires a tuner. In the meantime, I purchased a K3-KPA500-KAT500 with the Remote Rig/K3-I0 combo in August 2014 so that I could operate remotely as it was clear Flex was years behind in software development. Today, I use both Flex and Elecraft, but the ability to use an amplifier on all bands is only with the Elecraft. Lesson learned: Technology is really difficult to translate into quality products and that some companies have a better knack for translating a vision into a viable product than others. I enjoy the Flex system, but it has been a slow, painful process for software development and product to get to the point to where the product meets stated capabilities.

I _assumed_ that would happen when I (mostly) retired but it hasn?t yet - too many other interesting things that I?m still physically capable of doing - more serious radio will come later. I understand that folks paid serious money quite a while ago to get a spectacular radio and the combination of ?typical? delays in getting such sophisticated gear through production and shipping has been seriously extended by parts availability. All that is incredibly frustrating - I spent a couple of YEARS being customer technical representative for a couple of $1M+ ship-mounted mapping sonars that never really worked ?right.? It was a mess and I don?t expect Elecraft to go down that road but it puts me in the position of understanding both sides of the problem. >From my perspective as an owner of a well configured but rarely (yet) used KX3, I think about priorities like this: #1 - I want this (all) high quality manufacturer(s) of equipment I own to continue to be in business (if/when I need support some day) #2 - I also want them to have the resources (money, time , staff, tools, etc.) to continue to innovate while continuing to support older gear as long as parts are available #3 - To achieve #1 and #2, they also need the resources to mange the business, personnel, finances, etc. in addition to the engineering effectively. #4 - when I purchase their product I want to feel like I got a good deal. Achieving all of those is tough. As I often remind myself: ?Patience is a virtue, I?m gona get me some someday." -Dale > On Jul 31, 2020, at 11:05 , Joseph Trombino, Jr wrote: > > Howdy Gang. > > For all those Elecrafters who have plunked down kilo-bucks for the first K4?s coming off the line (when?grin?), let?s all ask Elecraft to reward out good faith by providing free shipping on said K4?s. > > Certainly would be a nice gesture, not sure about it being a good business practice though (grin). > > Looking forward to receiving my K4, hopefully before my 76th birthday in September!! > > All the best to Elecraft in these trying times in getting a product to market. > > Getting ready to put my Flex 6600M up for sale (grin). > > Stay healthy and enjoy. > > 73, Joe W2KJ > I QRP, therefore I am > ______________________________________________________________ > 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 > dale at ldeo.columbia.edu ______________________________________________________________ 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 ab4iq at comcast.net From norrislawfirm2 at gmail.com Fri Jul 31 15:27:45 2020 From: norrislawfirm2 at gmail.com (Eric Norris) Date: Fri, 31 Jul 2020 12:27:45 -0700 Subject: [Elecraft] Free shipping In-Reply-To: <0B11C30B-D8BD-4E6C-AC52-5F4075348A83@bellsouth.net> References: <0B11C30B-D8BD-4E6C-AC52-5F4075348A83.ref@bellsouth.net> <0B11C30B-D8BD-4E6C-AC52-5F4075348A83@bellsouth.net> Message-ID: Elecraft is a small, tightly-run company, who suffered the misfortune of discontinuing their flagship K3S just before a global pandemic struck and as they were trying to get a radically new worldbeater, the K4, out the door. They, like other responsible California companies, have put the health of their employees first. Those of us who remember the rollout of the K3 are familiar with the get-there-itis. One of my ham friends wanted a weekly update of where he was in the shipping queue. Those of us who paid for our KPA1500s a year before shipment remember the incredulousness of some who thought an interest-free loan for vaporware made us fools. Who could have anticipated that six months into the pandemic we would still be right back where we started due to apalling inaction from our country's leaders. I will wait patiently for my K4, and I expect to pay full shipping for it. In the meantime, my K-line is on the air nearly every day, giving me the same joy it has for well over a decade. Though my eyesight is fading with age, by now I know where all the K3 buttons are even in the dark. Sometimes I operate my K2, or K1, or KX1, and relive the excitement of building them. I hope all the Elecraft employees stay healthy, and Elecraft as a company stays healthy, too. I really look forward to operating my KX's out in the sunshine again with my buddies. The K4 will ship when it is ready. Stay calm, wash your hands, and wear a mask! 73 Eric WD6DBM On Fri, Jul 31, 2020, 8:05 AM Joseph Trombino, Jr wrote: > Howdy Gang. > > For all those Elecrafters who have plunked down kilo-bucks for the first > K4?s coming off the line (when?grin?), let?s all ask Elecraft to reward out > good faith by providing free shipping on said K4?s. > > Certainly would be a nice gesture, not sure about it being a good business > practice though (grin). > > Looking forward to receiving my K4, hopefully before my 76th birthday in > September!! > > All the best to Elecraft in these trying times in getting a product to > market. > > Getting ready to put my Flex 6600M up for sale (grin). > > Stay healthy and enjoy. > > 73, Joe W2KJ > I QRP, therefore I am > ______________________________________________________________ > 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 norrislawfirm2 at gmail.com From jasimmons at pinewooddata.com Fri Jul 31 15:35:13 2020 From: jasimmons at pinewooddata.com (John Simmons) Date: Fri, 31 Jul 2020 14:35:13 -0500 Subject: [Elecraft] [K3s] SteppIR Control In-Reply-To: References: Message-ID: <2cdcd758-d7c6-3202-5de8-e097cc4f366c@pinewooddata.com> K3 won't do both RS232 and USB at the same time.

I ordered a KVX3B board from the website she said they still have a few in stock. Also, the CBLP3Y cable is still available. If you have a P3 you will need that when you upgrade to the KIO3B. I ordered both. It appears the K3EXREF is still available. The KBPF3A says unavailable, but it let me put it in my cart. So, I'm not sure about that one.

A custom cable is required to allow the SteppIR auto-track to work via the K3 9-pin serial port at the same time. This is something I implement in my Serial Box (S-BOX ) offering so that one can use standard economical serial cables and omit all Y-adapters and expensive custom SteppIR cables. The serial cable connection from the SteppIR to the K3S serial port (via the Elecraft RJ-45 to DE-9F adapter cable, P/N E980297) must make no connection on Pin 3 (TXD), and Pins 7 and 9 must be shorted. Finally, a logging program must be actively polling the K3, or CONFIG:AUTO INF must be set to AUTO 1, or else the SteppIR won't get any frequency data. If you are also connecting a P3 via the CBLP3Y, then a serial Y-cable or S-BOX must be connected to the P3 "PC - RS232" port, with one side going to the CBLP3Y male DE-9 connector, and the other side going to the SteppIR cable. 73, Bob, N6TV https://bit.ly/S-BOX https://bit.ly/Y-BOX On Fri, Jul 31, 2020 at 12:36 PM John Simmons wrote: > K3 won't do both RS232 and USB at the same time.

You can connect your device to the RS232 data in two ways: 1. Use the RJ-45 to DE-9S cable plugged into the RS232/USB port on the K3 and sense the RS232 signals at the DE-9S connector. 2. If you have a P3 Panadapter connected to the K3, sense the RS232 signals at the connection to the PC connector on the P3. Never attempt to sense RS232 signals at the XCVR connector.

Low voltage at the antenna does not mean low voltage at the shack end of the feedline.? That's why it's called VSWR. 2.? Low voltage at the antenna does not mean low voltages internal to the tuner, which can be quite high depending upon the degree of non-resonance.? You aren't necessarily "making life easier for the matching unit" at all. 3.? Multi-band antennas mean highly variable pattern from band to band.? The same antenna might have a peak to the U.S. (from England) on one band and a major notch on another band.? If you don't care about pattern, dummy loads match pretty easy too. Multi-band antennas are fine as long as you recognize that they are a compromise.? I'd be interested in the reason why an antenna properly designed for a particular band is a bad idea. Dave??

In-Reply-To: References: Message-ID: IMHO, both the RIT/XIT knob and RIT clear button in the Kenwood ST-995sdr image are poorly located. I wouldn't recommend this radio for "big gun contesting" unless they offered an outboard RIT knob with an RIT clear button, like the Elecraft K-POD, or the old Ekletech outboard tuning knob (made by K9SD). Perhaps it was designed primarily for military use? However, I do like the concentric knobs in the Kenwood. Concentric optical encoders are (or were) quite expensive, which is why the K4 doesn't have any. The only concentric knob on the K4 is the AF and SUB AF gain knob, which is a POT. I expect this new Kenwood transceiver will generate sticker shock when the price is finally announced, similar to the Icom IC-7851. 73, Bob, N6TV On Fri, Jul 31, 2020 at 1:04 PM Douglas Zwiebel wrote: > http://www.cqdx.ru/ham/new-equipment/kenwood-st-995sdr/ > > de Doug KR2Q > From lrahnz at garlic.com Fri Jul 31 16:39:01 2020 From: lrahnz at garlic.com (lrahnz at garlic.com) Date: Fri, 31 Jul 2020 13:39:01 -0700 Subject: [Elecraft] That's a whole lotta buttons and knobs!

All Kenwood HF transceivers sold in the US since the early '70s have had a "TS-" prefix. I don't see Kenwood changing that designation. Has there been a brushed aluminum front Kenwood radio offered since their first dual-bander in the mid-'80s? I don't even thing the home entertainment line is available in anything but black. I tend to agree that this is an "artists conception". 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."

Any who are ahead of me that want to quit please do so get your money back so I move closer to the start of the shipping. My K4HD will be here when it gets here.
