BDR figures probably preclude use of K4 in Multy cathegory contest environment and? we need K4HD for that purpose which would hopefully have 140-150 DB of BDR. Is their more detailed report available from Elecraft or from Sherwood? I am especially interested in such a TX parameters as wide band TX noise, but other things would also be useful to know.

Same advice here, but especially look for one of these "brick amps" PRE-MFJ, when they were built on the west coast by two or more different companies. W6GJB and I were looking several years ago, and a post on the NCCC reflector brought four offers. They're essentially 150W amps, but models with different drive levels, from 2 to 30W. 73, Jim K9YC From jim at audiosystemsgroup.com Tue Jun 1 15:04:13 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 1 Jun 2021 12:04:13 -0700 Subject: [Elecraft] 2 meter PA In-Reply-To: <38C85868-3AD6-4168-8178-F837E294DF0A@voodoolab.com> References: <5B210F0A-7852-4577-9D18-EA06F3C77D1C@gmail.com> <38C85868-3AD6-4168-8178-F837E294DF0A@voodoolab.com> Message-ID: On 6/1/2021 11:16 AM, Josh Fiden wrote: > I had great success with an RF Concepts brick for quite a few years.

When I built and ran my portable kx3 S02r station which ran both occasionally through a trixplexer, filters and into a HexBeam, I had very little noticeable interference from one kx3 to the other.

In-Reply-To: References: Message-ID: Drew, KX3 is not the best radio for multi-multi environment. The radio automatically protects itself by switching preamp off if 59+20 signal appears on the band. With even stronger adjacent signal the radio engages attenuation. Blocking dynamic range of the radio is not for multi-multi. You would be much better off with several K3. They are probably still the best choice for this kind of operation both TX and RX wise. 73, Igor UA9CDC 02.06.2021 7:23, Drew Arnett ?????: > Anyone try a KX-3/KXPA100 for multi-multi HF contesting like Field > Day?

Personally, I like choices, so I've considered getting a 10MHz IF if I ever got deep into transverters. This would in theory allow full use of both 2 meters and 70cm with the same radio, if not some higher bands. Of course, I haven't looked into it too closely to see whether 10MHz is even workable given that there's also a 10MHz clock input on the Q5 transverters, so any thoughts on that would be good.

All split IF at 28 MHz, single antenna path for each, PTT low. I?d go with the high stability LO, especially at 432 or higher. The lower level drive works fine with the K3 and I believe the K3S transverter interface is identical in that regard. You can set it on a per transverter basis to get the drive you need. If you intend to use the same transverter on a different radio that does not provide a low level drive or a split IF, your choices may be different. One other thing to consider is how to select the active transverter if you add more than one. The Elecraft transverters have that built in, as they can read the Aux bus. For others you may need some external switching so that you only key the transverter that is selected. I use a band decoder from unified Microsystems for this. Of course if you connect only one transverter to your K3S that?s not an issue.

Both have the transmit delay set for 15ms. The amp is keyed directly from either rig using RCA/RCA cables from the SEND jack to the amp's keying jack. I do not use a keying line buffer between the amp and either rig. The amp has a very low voltage/current keying circuit. I also do not use the ALC line. Transmit power is set at about 21%. The only other important cables are the coax from the radio to the amp and from the amp to the tuner. I also have a cable from the 7300 or 7610 tuner port to the KAT500. Your LDG tuner probably already has the cable. I don't believe the LDG tuner can interrupt the keyng line to the mp the way the KAT500 can. You will need to be careful to put the amp in standby before initiating ay tuning operation so you do not hot switch the amp or provide it with a very high SWR or no antenna connection. GL!

PTT set for ground on transmit standard for all bands. > > High stability Local Oscillator vs. standard. This is an individual choice as all crystals are not created equally. I have a K3 with the garden variety ref oscillator. It is more than stable enough for digital modes.? The problem is typically the LO in the transverter itself. Crystals drift as temperatures change. I? have a 10 GHz transverter with a crystal oscillator and the drift from cold start to warmup is about 2 kHz at 10 GHz. After it is warmed up, I see only a few hundred cycles of ambiguity from day to day.? It was stable enough to make me not change over to a synthesized LO since sideband noise on the synthesizers was not so hot. Others have had more trouble with crystals drfiting all over the place. Not all crystals are created equally.? Cleaning the crystal blanks affects drift drastically. Production methods vary. Recently, I made some digital contacts on 222 MHz and found that my old crystal oscillator in my DEMI transverter drifted a bit. I saw a 10-12 Hz drift after each JT65 transmit sequence.? The problem is the power amplifier inside the trnsverter that heats up the crystal over time. My solution was to put a small 12 volt fan on the heatsink just above the hybrid amplifier location. It cured the drift. After employing the fan, people assumed that I was running a ref locked local oscillator. Measurements indicate a drift of just a few Hz over time.?? At higher frequencies, (over 432 MHz) some sort of reference oscillator arrangement is needed for digital modes. Cheap 10 MHz sources are available on EBay. Just make sure that whatever ref locked oscillator you use, that it does not produce bad LO noise sidebands.? I have a proportional oven 10 MHz crystal oscillator made by Wenzel Associates. It was cheap on EBay, and more than stable enough for any digital modes. You do not need a rubidium standard at all. > > I could get a custom IF and I think there is some slight advantage to a > 14mHz custom but I'm guessing the 28mHz standard IF is good enough? I use 28 MHz on 50 thru 432. On 902 and above, I standardized on a 145 MHz IF for everything up to 10 GHz.? 24 GHz has double conversion. 73 Dave K1WHS > > Thanks in advance for any advice or references. > > > > > > ----- > 73, > > Joe, W8JH > > K3s, KPA 500, KAT 500 and KX3 happy user. > -- > From FlatHat at comcast.net Thu Jun 3 09:56:47 2021 From: FlatHat at comcast.net (Richard) Date: Thu, 3 Jun 2021 09:56:47 -0400 Subject: [Elecraft] K4 Lore Message-ID: <84DA621F-26E1-4EC0-9915-2878A0336191@comcast.net> Does the basic plain vanilla K4 have a built-in antenna tuner?

I then added a T1 tuner so I could use the tuner with other QRP radios. This setup worked quite well, if not a conveniently as an internal tuner in a K3. Then my wife, after watching me work QRP in CQP with marginal antennas said, "Oh go out and get the 100W amp." The order went out very quickly, before she could change her mind. I had some matched antennas and they worked well at 100W and I reduced power for the bands which needed the T1. After hitting the T1 with 100W a couple of times -- it survived and still works well -- I got the internal tuner in the K3. I'm a happy camper. 73 Bill AE6JV ------------------------------------------------------------------------ Bill Frantz |"Insofar as the propositions of mathematics refer to 408-348-7900 | reality, they are not certain; and insofar they are www.pwpconsult.com | certain, they do not refer to reality.? -- Einstein From jh at hoffmaninv.com Fri Jun 4 15:12:43 2021 From: jh at hoffmaninv.com (W8JH) Date: Fri, 4 Jun 2021 12:12:43 -0700 (MST) Subject: [Elecraft] K3s and DEMI transverter In-Reply-To: <1622640766882-0.post@n2.nabble.com> References: <1622640766882-0.post@n2.nabble.com> Message-ID: <1622833963134-0.post@n2.nabble.com> Many thanks for the replies.

When the pin diodes fail you generally get major signal loss across all bands. The description simply does not match that diagnosis. I would ask for further information: * Is there any change in 160m transmit operation (change in drive requirement)? * Was any retuning of the 160m antenna required? * How is the 160m antenna connected? Might it be split to another load somehow? * Any other changes you see? Let?s try to diagnose the whole situation.

Semiconductors: Issues: Energy Protection level, RX Intermodulation prevention. There are however some fast semiconductor diodes (ESD protection) available with low capacitance. They have safe enough voltage protection level even for sensitive RX electronics, but limited energy absorption. Spark gaps: A several kV, ns-fast, transient (ESD, EMP, high dV/dt) voltage RX input spike may be better limited in energy but more voltage amplitude; still around 800 to 1000V left over for a short time. Suitable spark gap can trigger quickly (dV/dt dependent). There is always some time delay in gap breakdown. Sensitive RX components need to survive that safely, without being pre-damaged . This low pressure gas ionization process is also governed by HV breakdown Paschen law https://en.wikipedia.org/wiki/Paschen%27s_law . The number of first available free gas electrons, needed for a quick avalanche breakdown, are important. By gap fast overvolting (field emission process from electrodes-> source of free electrons, without radioactive , ionizing material ) the spark gap is triggered. The gas tube would fire at much lower DC voltage levels ( e.g. <100.. 200V+ ) Fast pulse triggering creates a very broadband spectrum of the residual onset pulse (Time -Frequency Domain Fourier transformation ) . This triggering is different from a finally, time retarded, development of low resistance breakdown plasma channel. Here the residual voltage may be 30 to 50V. Too bad, the first spike may have already killed the RX. Therefore , if capacitance is not an issue (no HF RX) , one uses low pass filters after the spark gap. To control the energy reduction one can use additionally multi-stage protection modules ( 1.) Gap tube-full energy ,2.) elevated energy semiconductor, 3.) low energy semiconductor ) The triggering of the stages must be well time coordinated. If AC voltages are continuously present in PS Networks , the spark gap (low R Plasma) network follow on currents must be limited to lead to well controlled extinguishing of the gap. PS: One other trick to avoid high capacitances (high VSWR) is to arrange protection diodes in a bridge configuration -cancelling out C One other trick to avoid intermodulation is to DC bias diodes appropriately. Experience furthermore teaches: Even 4 unbiased Schottky Diodes ( ca. 0.3V each ) in series/anti parallel at RX front end are often critical regarding INTERMOD , e.g.in multi TX contest site scenarios ) End of lecture ...if considered too long and irrelevant just ignore it Hi Hi ? -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dr. William J.

A few more runs plus an antenna switch will be on order soon.? Four antennas should give me paths into much of North America.? If the bands ever strengthen the world may open up again.?

There were a few African contacts with at least one from the Middle East. None, so far, from South or Southeastern Asia.? I did forget to mention both Australia and New Zealand.? I missed Antarctica but logged him via relay. ?? I started the Elecraft CW Net on June 6th, 2002.? Many people have checked in over the years.? The format of the directed net was designed by N0SS, Tom Hammond (SK).? He helped for many years as an alternate net control from Missouri.? I miss him.? Wayne, N6KR, once asked me how I had kept running the net for so long.? I told him it had become a habit.? A good habit.? One where I get to meet new people and learn a bit more about the regulars.? I think I have been skunked only once and for only one of the two nets. Sometimes the bands are just too poor.? Other times folks are busy with holidays.? But I still get a few folks each week. ?? Procedures have changed a little since the beginning.? I am finally learning how to run a net.? The only strict rule is to have fun.? Well, the directed net part is kind of strict too, but without some control there is chaos.? Much like the transition from laminar to turbulent flow.? A little disorder is OK as long as everyone knows who is talking to whom.? "Little whorls have lesser whirls and so on to viscosity." ? Tomorrow will be the 19th anniversary celebration of the Elecraft CW Net.? Lime jello, cookies, and cherry pie for the lucky few.? Oh and fresh sour dough bread.? Now for an entree :) The rhododendron are in full bloom as are the nicely scented False Solomon Seal.? Many species of butterflies are enjoying a feast. Both species of hummingbirds are on display (Rufous & Anna's).? So warm up your heaters and get? your tubes glowing (I can dream) and see if the bands will support comms to NW Oregon (where it is back to 50 degrees with rain).

The K4 adds several important new wrinkles: 1. Up to 12 transverter bands Each transverter band has a corresponding button in the band selection group. Each band can be customized for lower band edge (up to 99,000 MHz), IF (0 to 53 MHz), oscillator error offset (+/- 99.999 kHz), and power level (0.1-5.0 mW). XVTR buttons display their lower band edge in MHz. 2. Convenient switching between HF and transverter bands When you tap the BAND button, you'll see the currently selected band within either the HF or XVTR band group. An additional button will be labeled either XVTR or HF, allowing you to easily switch to the last HF band if you were on XVTR, or XVTR band if you were on HF. VFO A can be on HF while VFO B is on a transverter band, and vice-versa. If the sub is on you can monitor both an HF band and an XVTR band at the same time. 3. Independent dual receive with two external transverters (K4D) If you have two external transverters, you can use RX ANT 1 for one and XVTR IN/RX ANT 2 for the other. With the sub RX on, you can then listen to both transverters at the same time, with stereo audio. You can then use the SPLIT control to determine which transverter is selected for transmit. (For this purpose, you'd need to drive both transverters' IF inputs from the XVTR OUT jack.) * * * The transverter band feature will be available with release 18 of the firmware, due out soon. 73, Wayne N6KR From kevinr at coho.net Mon Jun 7 01:42:29 2021 From: kevinr at coho.net (kevinr) Date: Sun, 6 Jun 2021 22:42:29 -0700 Subject: [Elecraft] Elecraft CW Net Report 19th Anniversary Edition Message-ID: <1f386b7e-f2df-ce8c-a1ac-e1b41eedb0c4@coho.net> Good Evening, ??

It seems to me that I should be able to connect a splitter between the RX Out and RX In ports on the K3, and use that to feed the SDR by pressing the RX Ant button? (at a cost of ~3.5 dB loss, of course).? Question is, what happens when I go to transmit - is the RX Out line muted so that my SDR won't try to spot me?

I'm probably far down the list anyway. Their are numerous reason for this decision. First, there is the cost. With a tuner the price is $4600 making it one of the most expensive transceivers on the market. I fully realize that the K4 is feature rich and extremely well designed. I would never take anything away from Elecraft's engineering ability. The K3 set a new standard of performance that made the other manufacturers substantially up their game - which they did. But is the K4 going to do the same thing the K3 did? To me, it doesn't look like it. Innovative in some, perhaps many ways - yes. A new trend setter? I'm not so sure. When the K3 came out it was very competitively priced. I'm not sure I would describe the K4 with the same words. It is unquestionably an expensive radio. At this point the price/performance just isn't there for me. I sold my very complete K3 station several years ago in anticipation of the K4. But now the waiting has left me thinking about how much I'm willing to invest and whether or not another brand whose transceivers are as much as $1500 less and whose performance seems quite impressive will meet my needs. After literally several years of contemplation I conclude that, for me, the K4 is not worth the price. $3600 (with the tuner since every other significant radio includes one) would seem competitive and I would jump on it at this price. But as it is? Can't see doing it. I apologize if feelings are hurt or I've made anyone angry. I'm leaving the list since I'm no longer waiting patiently for what we once called Vaporware. Good luck to everyone on their current and future K4s.

The last time I started operating, I noticed that my P3 did not know the frequency the K3 was using. I then noticed that I hadn't plugged the USB connection between the K3 and the computer into the computer. I plugged it in and everything worked again. I think this may have been because the K3 needs to be polled in order to send the frequency data. (There is a menu option to automatically send the frequency data. I am away from the radio so I can't check how it is set on my K3.) Hooking the radio to my computer let the logging program provide the polling. 73 Bill AE6JV On 6/8/21 at 10:15 PM, gthornton at thorntonmostullaw.com (George Thornton) wrote: >I have a more or less fully loaded K3 with the synthesizer >upgrades.

I'm probably far down the list anyway. Their are numerous reason for this decision. First, there is the cost. With a tuner the price is $4600 making it one of the most expensive transceivers on the market. I fully realize that the K4 is feature rich and extremely well designed. I would never take anything away from Elecraft's engineering ability. The K3 set a new standard of performance that made the other manufacturers substantially up their game - which they did. But is the K4 going to do the same thing the K3 did? To me, it doesn't look like it. Innovative in some, perhaps many ways - yes. A new trend setter? I'm not so sure. When the K3 came out it was very competitively priced. I'm not sure I would describe the K4 with the same words. It is unquestionably an expensive radio. At this point the price/performance just isn't there for me. I sold my very complete K3 station several years ago in anticipation of the K4. But now the waiting has left me thinking about how much I'm willing to invest and whether or not another brand whose transceivers are as much as $1500 less and whose performance seems quite impressive will meet my needs. After literally several years of contemplation I conclude that, for me, the K4 is not worth the price. $3600 (with the tuner since every other significant radio includes one) would seem competitive and I would jump on it at this price. But as it is? Can't see doing it. I apologize if feelings are hurt or I've made anyone angry. I'm leaving the list since I'm no longer waiting patiently for what we once called Vaporware.Good luck to everyone on their current and future K4s.Doug -- K0DXV______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:Elecraft at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to turnbull at net1.ie From gthornton at thorntonmostullaw.com Tue Jun 8 02:53:26 2021 From: gthornton at thorntonmostullaw.com (George Thornton) Date: Tue, 8 Jun 2021 06:53:26 +0000 Subject: [Elecraft] Giving Up In-Reply-To: <60bf0db5.1c69fb81.4d292.3a00@mx.google.com> References: <60bf0db5.1c69fb81.4d292.3a00@mx.google.com> Message-ID: I agree that the price for the K4 has to be compared with the fully loaded K3 plus P3.

I will keep my K3 and KX3 though and will possibly consider FTDX10 which sounds like a good value for money. If only Yaesu did not have those tiny difficult to find and deal with connectors. I have also got used to at least 3 audio output ports on K3 with own AF amplifier each. UI on Elecraft radios is sure much better thought out but the price tag overweight. 73, Igor UA9CDC 08.06.2021 11:53, George Thornton ?????: > I agree that the price for the K4 has to be compared with the fully loaded K3 plus P3.

The problem is hams thinking the order of listing is based on an overall figure of merit. It is *not*. Rob had to choose *one column* on which to sort his list. When he first published it, he chose third-order dynamic range (narrow spaced), probably because many receivers *of that day* had poor performance on that important metric. For consistency, he has chosen to retain that sort order even though many (most?) modern receivers have improved to the point where that particular parameter is almost irrelevant when choosing among top radios. George is correct that most of us can't tell the difference among radios due to minor differences in DR - they are ALL excellent and Rob is careful to point that out when he speaks at hamfests. In fact, most modern transceivers excel in so many receiver performance metrics that Rob and others are now rightly crusading for improvements in transmitter performance which has not advanced as much as receiver performance across the industry. K4 (and K3 before it) and a few others have excellent transmitter IMD and clean keying that make them best choices, especially in crowded or multi-transmitter environments and among hams who care about not generating unnecessarily broad signals. That plus ergonomics and operating features should be the new basis of comparison but they don't fit on a list of *receiver performance* metrics. I'd like to see a new table of select transmitter performance measurements. Ergonomics and feature sets don't lend themselves as easily to tabular comparison except by manufacturers who can choose which things to mention, so it's important to read the descriptions, read the reviews, listen to owners and, if still unsure, sit down with the radios before making a decision. The Sherwood data is good. Just don't interpret it the wrong way. 73, /Rick N6XI On Mon, Jun 7, 2021 at 11:54 PM George Thornton < gthornton at thorntonmostullaw.com> wrote: > I agree that the price for the K4 has to be compared with the fully loaded > K3 plus P3.

Using the 200Hz narrow filter in the K3, I could hear weaker CW sigs, with no keying artifacts, between, eg, W3LPL and K3LR adjacent each other, even though they pinned the meter thru the wider filters. The "comparison" rig, a Yazoo '857, was unusable on contest antennas on contest weekends. Tks to all those who have described mods to clean up the offshore dirtysig clickmachines instead of using the artifacts to hold a run frequency. W8JI.com, for example, has or had mods that clean up the clicks produced by the venerable FT1000 rigs.

I note these Yaesu rigs seem to have crystal filters and use a combination of superhet and direct sampling architecture whereas the K4D is direct sampling. I would hold off on reaching conclusions on relative performance until the K4HD comes out and is tested.

That was the year I bought my K3-10* (since updated with new synth).? I bought DEMI 144-28, 222-28, 432-28* and 1296-28 transverters as better design filtered LO better making 28-MHz a good choice for use with my K3.? Note: * indicates use of PLL locked to 10-MHz reference resulting in less than 2-Hz max drift on 28-MHz.? Choice of LO frequency is determined by ability to reject LO feed thru (primarily). Picking a too low IF can lead to troubles. I also have DEMI 3400-145* and 10,368-144* transverters.? Use of 144 or 432 as IF at 1296 and above is common.? They use the N5AC A32 PLL to lock LO.? The A32 is now NLA so look at DEMI digiLO as replacement.? Currently using an OCXO as 10-MHz ref but will switch to GPSDO this summer. Eventually Elecraft will offer 144 and 432 transverter modules for the K4.? Will be curious what IF is chosen. 73, Ed - KL7UW On 2 Jun 2021, at 15:46, Mooneer Salem wrote: Personally, I like choices, so I've considered getting a 10MHz IF if I ever got deep into transverters.

The other IF commonly used is 14MHz (by Kuhne for example), but we use 28MHz on all our VHF and up contest transverters. If you want to see how we do with this arrangement look up G5LK/P and G3M in the UK listing for the major portable contests.

I would not say the K4 is materially worse. I think it would be up to individual K3 owners to decide whether to sell and pay the difference for an upgrade. I looked at pricing for the Yaesu stuff and the comparable dual receiver model comes out at $4700. Their 200 watt version is advertised at $5200. We don't really know how much the superhet option will cost but what if it was a grand more, that would put the top of the line K4HD at $5000. At that level I would look more at a full feature comparison before I reached a conclusion about which is a better deal. I don't have full information on pricing and options so I don't know if my numbers are off. We are dealing with a US company versus foreign made and that may also be a factor. I also suspect Elecraft could in the future come out with a scaled down model that has only one receiver and that could become a lower cost option. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of David Gilbert Sent: Tuesday, June 8, 2021 12:08 PM To: Elecraft Subject: Re: [Elecraft] Giving Up Except that the K4 (not K4HD) does not equal the K3 for raw performance.?

Elecraft has made a marketing decision to market one radio and it is priced in the middle of the Ham-consumer pack with other radios with similar performance. They have opted to skip the entry-level market (like Icom with the 7300 that you can get for basically $1000, and a range of radios at different price points). Many people can't pony up the $4,000+ for the new (now) entry level Elecraft (no matter what the performance) and will go elsewhere for their radios. This is a different model than the entry level K3 that initially started barely over $1,000. That's what's up here... As Rob says in all of his talks... "Any of the radios in the top 10+ are about the same in performance... you serve yourself best buying one with the options that suit you". Unless, of course, you are a performance number chaser...

I bought a 7300 because I thought it would be a descent backup to my K-line (K3). Two months after I bought it, I sold it for a net $200 loss. I did the test that Don outlines in his message quoted below. I searched for weak CW stations on my K3 and then switched the antenna over to the IC-7300 to see if I could pick them up. Not a a precise experiment but I would say about half of the weak signals I could hear enough to copy on my K3 were not copyable on the IC-7300 and a few of them were not even making an appearance. This test was all done with my 20-meter dipole near the resonant point of the antenna so no tuners were involved for either radio. But, that was not the kill-shot for the 7300. The relay clicks on break-in keying drove me crazy. 73, phil, K7PEH > On Jun 8, 2021, at 4:58 PM, Bert wrote: > > Here is the $ 64.000 question: > > Do you think you can work more stations with a K3 vs a 7300 > everything else being equal, antennas, location, etc.? > > Bert VE3NR > > > > On 2021-06-08 19:52, Ray wrote: >> >> Like the Old Saying?? >> If you cant Hear them You cant Work them???. >> That is WHY that is a $1000.00 Radio. >> Good Luck Hunting the DX?? >> >> Ray WA6VAB K3 >> >> >> From: Don Wilhelm >> Sent: Tuesday, June 8, 2021 4:35 PM >> To: Richard; Elecraft >> Subject: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 >> >> Richard and all, >> >> I have a friend who bought a K3s and then afterward bought an IC-7300. >> He is a weak signal CW type of guy and reports that there are many weak >> signals that he could copy on the K3, but were non-existent on the IC-7300. >> >> His reason for buying the IC-7300 had to do with possible "portable" >> operation.

I came prepared to test the radio. After having downloaded the manual and reading it through 3 or 4 times getting the menus, setting, knobs, filtering, general settings well in my head, I went to the store and turned one on for about 2 solid hours. I was so upset with my K3S/P3 costing over 6K$ being shown up by a $1700 radio. Granted it does not have all the bells and whistles that the Elecraft had but for a great receiver, it blows the K3 away with band noise, and electrical noise mitigation. I found the receiver to be much quieter over all and with no harsh roar constantly as the K3S has. The Pan Adaptor was way easier to use and adjustment to 5khz wide was a S&P dream to operate with an adjustable notch and contour peaking or nulling functions continuously variable for best reception. I went home and got my money back from Elecraft, $9879, they had it for over a year, and once it was in my account I ordered sight unseen and untested both FTDX101MP and D models. The MP came first. I had the D sent to the factory to install the extra 300hz cw filter. Putting the K3S/P3 on an A/B switch with the MP, the difference was astounding. I immediately listed the K3S/P3 and sold it within an hour. It went out the next morning to UPS and I have had no regrets. Both my son, NS0R, and I operated the Yaesu's in multiple contests. This was the first time in my life that we could hear stations that we could not work. Having the Yaesus was an absolute game changer for me. The VC tune is the money. This last WPX cw we increased our score by a million because we could hear stations that the K3 was deaf to. The Band noise and intermittent electrical noise in the city was easily managed by the FTDX101MP. The K3S could not even come close to this performance. Simply put the FTDX10 and the FTDX101MP/D just have better receivers, due to the noise mitigation, lower internal noise, easier to listen to for long periods, and features like the adjustable notch and contour controls coupled with the VC tune and remarkable DSP, width and IF shift controls...it is just not a little bit better, it is atleast a magnitude better. Running SO2R on a city lot with cramped antenna space is not a problem. They are clean and no phase noise/composite noise is detected on transmit in the other radio on receive. I have them side by side. I have given 2 or 3 presentations on Zoom to explain how I use the rig and the great noise mitigation that It can do. When you push a button or turn a knob on these radios, something happens. They are not there for display. FTDX101MP and D---The best radios I have ever owned or operated. 73, Morgan NJ8M On Tue, Jun 8, 2021 at 6:55 PM Ray wrote: > > > Like the Old Saying?? > If you cant Hear them You cant Work them???. > That is WHY that is a $1000.00 Radio. > Good Luck Hunting the DX?? > > Ray WA6VAB K3 > > > From: Don Wilhelm > Sent: Tuesday, June 8, 2021 4:35 PM > To: Richard; Elecraft > Subject: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 > > Richard and all, > > I have a friend who bought a K3s and then afterward bought an IC-7300. > He is a weak signal CW type of guy and reports that there are many weak > signals that he could copy on the K3, but were non-existent on the IC-7300. > > His reason for buying the IC-7300 had to do with possible "portable" > operation.

Message-ID: Just to mirror what Ed mentioned? I have my complete 160 - 5G station running off of my K3 bought in 2011 and upgraded. I have the internal 144 transverter which had to go back 3 times to get spurs sorted out. One think I note, is signal compression as I have pagers just below 144 Mhz and when they fire up They desense the 2 m transverter?. I?ve correlated this with an SDR. The problem is lack of filtering in the internal transverter as the front end sees well beyond 144 - 148. The solution was to add a filter with a steep rolloff below 144 Mhz? I would hope that the guys at Elecraft when designing the new K4 transverter system will take a cue from DEMI and Q5 and ensure adequate Bandpass filtering in the front ends? I would think TOKO or similar are your friends on this ? Just my 2 cents. I use the 2 m to drive all my microwave stuff as well and with GPS locking its nice to be able to know where you are ? Having said that, Q5 have a really slick multi band transverter that would integrate really well on the K3 or K4? but at a price point. Anyway I do hope Elecraft come up with something that is crunch proof and rock solid for 144 222 432 MHz. 73 Dana VE3DS From kc4atu at hotmail.com Tue Jun 8 20:32:34 2021 From: kc4atu at hotmail.com (Bill Rowlett) Date: Tue, 8 Jun 2021 20:32:34 -0400 Subject: [Elecraft] Other Radio lists thoughts.

On the -7300, I have to guess which of four buttons a given setting is behind.

In-Reply-To: References: Message-ID: I dunno, this seems like it's worth trying. I think there are roughly these steps: 1. Identify the radios we care about. Icom, Kenwood, Yaesu, Elecraft, and FlexRadio's current HF offerings, plus the cult favorite Xiegu G90, seem like a good place to start. 2. Identify the controls we care about. I could throw together a quick list based on what I use and what radios commonly feature as front panel controls, and solicit additions from the list. 3. Identify the operator classes we care about. I think rag-chewing / contesting / weak-signal are good classes, plus CW / SSB / digital; I'd be open to hearing other additions. 4. Trawl through the manuals for the radios and note how each relevant control is accessed. This is tedious, but the kind of thing I would find oddly enjoyable. 5. Estimate or observe how frequently and/or urgently each operator class uses each control. We could throw together a quick estimate, and could later refine it by surveying or observing folks who inhabit those classes. 6. Do the math on what we get from steps 4 and 5 to generate some scores. Anyone interested in contributing to step 5?

Skimmer won't spot your own call, but it will usually spot busted variants. I recommend disconnecting your skimmer from the RBN when operating at the same site. Local RF will usually leak into the SDR even with no antenna connected; the SDR is very sensitive.

In this my second attempt, let me say that I've always been amazed at the power wielded by Rob Sherwood. Thousands of hams hang on his latest tests. If he deems a new radio exceptional in some way, that can mean many millions of dollars for a manufacturer. And yet, if there were no such thing as gurus on the web and at places like Dayton expounding about how Brand A is better than Brand B, how would you answer the questions, "Do I like this transceiver?," and, "Is it any good?" You'd probably get on the air and use it, and decide that way. But we constantly have gurus telling us that Brand A is the 'best' which horrifies us if up until now we liked Brand B better. Against our personal experience we flip-flop and say, "Gee, I used to like Brand B, but Brand A must be better because the gurus say so." Yet, there will always be guys who'll be tortured owning a transceiver that has the 2nd highest dynamic range, or the 3rd best distortion. Never mind if they can't actually hear the differences. It's how a rig *sounds and feels* during actual operating that's most important. Not the numbers. For instance, Wes made a comment about his tuning knob, and although some of you might have laughed at that... it's darned important! That's the kind of thing I'm talking about. Here's my opinion on ranking receivers by 2 kHz 3rd order dynamic range: almost any modern receiver has enough dynamic range to make this ranking more and more meaningless as time goes on. Sherwood himself has said that 90 dB or above is plenty enough. To understand why, see this post from 2016 by one of the old guys on this reflector:?http://elecraft.365791.n2.nabble.com/K3-The-Way-We-Rank-Receivers-long-td7623639.html? Lastly, if you've been enjoying your rig for years and then hear someone else complain about a flaw you weren't even aware of, don't panic. There are a million reasons why his concerns might not involve you in the least. Above all, have fun.

If it brings you joy to have the highest performing rig you can, cool, and I hope it serves you well. But if a different aspect of a radio, or even one you can't name, brings you joy, that's also cool, and I'm happy it makes you happy! My KX3 isn't at the top of the Sherwood list, it doesn't have a panadapter (...yet), and connecting it up for digital modes is a bit of a rat's nest... ...but I'll be darned if it isn't just fun as shit to use. The UI is well thought out, the VFO knob is a work of art, (surprisingly) the compact size makes it more approachable/friendly for it, and the community here around it (as heated as it can get) is tighter-knit. None of those show up in a spec sheet or lab testing Get what makes *you* happy, and share your experience so the next ham can do the same.

All, I followed along this thread and I think it's not useful to compare the K4 to the K3. The K3 to the K2 makes sense, even a KX3 to a K3 as they are more similar. I think the only radio on the market right now that can be compared to the K4 is the 7610 from ICOM. And frankly, it's not so good for the K4. A little over a year ago, I was in the market for a high end transceiver and basically decided between waiting for a K4 or buy a 7610. I bought the Icom. While I am sure the K4 is a better radio in some ways, the question is: is it twice as good? (Add tuner, second ADC, etc.) Looking at the specs, I am shocked the K4 is shipping with only one ADC. At the price point and with the 7610 on the market for $2900 all day long it's a serious flaw for me. The K4 also has no pre-selector that I can tell and that is useful too me at times, especially on the low bands. IMO the competition for the K4 is the 7610 as they are architecturally very similar. Maybe an Apache ANON 7000 DLE would be in there as well but the Icom beats that too IMO. (Since it has buttons, and a tuner, and pin-diode QSK etc) That said, I have since bought a K3 to go with the 7610 and will likely get a K4 and an ANON in the future so I am as hopeless as the rest. 73's all. -- Dave Erickson AB0R 73 From FlatHat at comcast.net Wed Jun 9 00:15:51 2021 From: FlatHat at comcast.net (Richard) Date: Wed, 9 Jun 2021 00:15:51 -0400 Subject: [Elecraft] KPA500/KAT500 With a Yaesu FTDX10 Message-ID: <60E94DF2-78A9-41E2-9896-79BC13880F61@comcast.net> If you are using a Yaesu FTDX10, especially with a KPA500 and KAT500, please get in touch.

I have always got to buy and try all the newest rigs and then move them on if I am not that smitten. My current rigs/keepers are a K3 (2008 vintage), TS890, Omni 6+, Orion 2 (three of those !), SunSDR2DX. Been and gone rigs include the IC7851, IC7610, TS990 (only because it got too heavy for me so I got the TS890), MB1, Flex 6600M and a number of others. I have not yet succumbed to the FTDX101 or the FTDX10 but may give one or the other a try. However, one of my main requirements is good quiet QSK so I am not sure that the Yaesu is suitable and the bandscope strikes me as horrible. I too have had a no deposit K4D on order for about two years. I intend to just let the order sit there and see if anything eventually happens and if it does I expect I will buy it !!

Be sure to be aware of its limitations before you buy it. For example, the FTdx101MP has three show-stoppers (for a CW op like me), despite it's impressive numbers in the Sherwood table: - Poor QSK performance (the clicking keying relay cannot be disabled, same problem as the IC-7300) - No CW sidetone output on USB Audio CODEC-- cannot record both ends of your QSOs (a contest requirement in some contests) - Mouse wheel is not supported for fine tuning or RIT (I think). K4 supports this very well As for comparing the K4 to the K3, despite the K3's "superior" numbers in the Sherwood table, the K4 SOUNDS so much better than any K3. The K4 audio is just SO CLEAN compared to the K3, which makes a big difference when a pileup calls. That quality is not captured by any subjective measurement. The narrow DSP filters (down to 50 Hz) also seem to work so much better in the K4 than the narrow 250 or 200 Hz crystal filters in the K3 -- no ringing. 73, Bob, N6TV On Mon, Jun 7, 2021 at 7:34 PM Doug Person wrote: > Sadly, I've decided to give up waiting for the K4.

Neither the KPA500 nor the KAT500 can auto-track the frequency any Icom rig by itself. Instead, go for the KPA1500 with its built-in tuner, which auto-tracks *all* Icom rigs via it's 2-wire REMOTE (CI-V) connector quite perfectly. The KPA500 XCVR serial port and KAT500 PC DATA port are completely compatible with Kenwood's serial ports for auto-track, but the KPA500 XCVR interface is NOT compatible with Yaesu rigs, because Yaesu's frequency commands don't match the Kenwood standard properly (not enough leading zeroes, something Elecraft may be able to handle some day with a firmware update to both the KAT500 and KPA500). The KPA1500, on the other hand, WILL auto-track any modern Yaesu rig via serial port just fine. My Serial Box can help with the interconnections to both using stock molded cables, so no homebrew or expensive custom cables are needed. Though you can wire the LINEAR connector of a Yaesu rig to a KPA500 AUX connector, and it will auto-track band changes perfectly, the KAT500 will not track the VFO frequency, so it's only half of what you requested. So in sum, if you're looking at any Icom or Yaesu rig, consider the KPA1500 instead of the KPA500/KAT500 combo, or wait for new firmware to support Yaesu's frequency format. Icom support in the KAT500/KPA500 is not possible, only the KPA1500 has the hardware. Another option to consider is N4PY's Pegasus Plus software, which will translate Icom and Yaesu frequency data to Kenwood format for the KPA500 and KAT500. The S-BOX-USB can be configured as a null-modem cable interface to connect N4PY's software to both the KPA500 and KAT500 using a single USB port on the PC. 73, Bob, N6TV https://bit.ly/S-BOX From jim at audiosystemsgroup.com Wed Jun 9 04:22:31 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 9 Jun 2021 01:22:31 -0700 Subject: [Elecraft] Gurus In-Reply-To: <8fc0725c-8ed5-c26d-85c1-594a22ba9ed2@gmail.com> References: <716584982.5215873.1623203828375.ref@mail.yahoo.com> <716584982.5215873.1623203828375@mail.yahoo.com> <8fc0725c-8ed5-c26d-85c1-594a22ba9ed2@gmail.com> Message-ID: <0c73bdb3-c44d-2a70-f504-e3b4e1ad4a91@audiosystemsgroup.com> Exactly right, Vic.

I own a YAESU FTDX101MP ( SW/FW upgrade April 2020 ) since 1 Year and am very impressed by the high performance (I do SSB , also QRO CW; ragchewing/ DXing/ Contesting). This unit YAESU is partly even better than Tx / RX K3S, but not for QSK (relays chattering) . I would like to bring the following, unexpected findings -should get fixed a.s.a.p.- to your attention (or did I overlook something?): 1. Voice Messages (e.g. CQ) can be recorded e.g. in SSB and CW. Bacon Mode (automatic , interval repeat) is only possible in CW not in SSB , very impractical. 2. Incoming signals like QSOs cannot be recorded by the TRX directly. 3. The TX PWR Meter should read PEP not average. 4. 60m (5MHz) there is no sharp preselector available (VC Tune). It is also not possible to activate VC Tune on 12m, 6m. 5. RX: IPO to AMP1 to AMP2 is about a 10dB difference each step (20dB range) , Input RX Attenuator is correct with -6, -12, -18 dB 6. S-Meter Calibration 160m to 6m is not always real as (IARU Definition) S9=-73dBm or 50uV/50Ohm. Yes, below S9 there are -3dB steps per S-Unit, above S9 meter indication is correct as shown 7. The band scope needs different sensitivity settings for viewing RX and own TX signals. If optimized for RX, you will see a completly distorted/ overloading signal in TX mode ! * 160m to 40m: real S9 (AMP1) is more like S 7.5 on the meter, with IPO more like S 4.5 e.g. on 40m * 20 to 6m: real S9 is about S9 (AMP1) on the meter * Knowing about this I can live with it, easily. On the low bands the S-Meter is not very generous. A much more critical issue for some RX denoising applications is ? Tricky Antenna port selection , accessibility to Input RX1 and RX2 individually not possible (diversity or local QRM reduction by phasing?) * There are 3 Ant. Ports. * There is a RX1 out and RX2 out port, obviously only , individually selectable via menu * Normal Configuration: T1 is TX and RX Port-> measuring the RX signal attenuation between T1 (AMP1 , ATT 0dB, VC Tune on) and e.g. RX1 out: It varies, from 160 to 30m?15m from -6db/-9dB, on 12m it is suddenly +5dB, on 10m there is 0dB. On the low bands there is a considerable signal loss! * Special RX Ant. Configuration: port One (#3) can be configured e.g. as RX on 3 only , while T1 is only transmit * Configuration R3 (RX only: AMP1 , ATT 0dB, VC Tune on), T1 TX only. Measuring the RX signal attenuation now between RX only import and e.g. RX1 out: -10 dB on 160m, 80m -3dB, 60/40/30/20m -5dB, 17m -7dB, 12m +6dB, 10m +2dB. The mostly relatively sharp frequency band selection (VC Tune) is clearly visible. * Problem/Dilemma with using an external RX phasing/ QRM Eliminator, there is now a missing function of routing the Main (TX) /RX Ant 1 Signal safely through to an RX outport (as in K3S). In FTDX101MP it is either RX all on Ant 1 or all RX on R3. * The phasing unit NCC1 with me has 2 channels: A noisy main Antenna, B noise local noise pick-up by a 1m diameter magnetic broadband loop. The S/N improved, vector combined output port signal must go to the Transceiver RX input port ( e.g. R3). * Therefore the safe routing through of the main antenna (only Rx function ) is badly missed here. * Envisioned external solution: Order/Installation of a separate, ?Modular Receive Antenna Interface for Transceivers DXE-RTR-2? in front of the FTDX1001MP I also own a Elecraft K3S and did some EMI (Electromag. Interference) coupling experiment into the power supply (PS) port. This is another, aside from antenna port, important EMI port and potentially causing uncontrolled RX coupling. The effect is often overlooked. Conducted EMI -on the PS- of TRX ( Transceiver) results in backdoor coupling , if e.g. using external 12V (13.8V DC) external PS in a station. Investigation: Elecraft K3S ( minus on chassis ground and grounded by terminal (stud) to station ground => risk of loop formation with PE protective earth): Lab-Testing in a well-controlled coupling experiment (TRX Antenna terminated with DL 50 Ohm , 12V Battery operated-20 dB choked off, EMI injected capacitively into TRX plus, minus on GND ) * one can show S3 on the S-Meter on 80m for already some 20mVpp CM voltage ( 12V DC plus/minus input of TRX). * In the same test on 20m it takes just 30mVpp to reach S8 We have seen over 100mVpp induced on the 13.8V DC supply voltage in a K3S experiment 28MHz, 60W into Dummy Load 50Ohm. Using a MDS-clamp (EMC Test 30M-1GHz, --CISPR 16-1-3--, applicable to only on cable connection on K3S) test on the DC supply line resulted in 76dBpW ( about 40 micro Watt @28 MHz). This test is a "simple system configuration substitute" for a radiated test. An anechoic chamber was not available. >From this one can estimate the 100W PA shielding/filtering efficiency to be about 62 dB [10xlg(60W/40uW)]. This is not unusual, rather reasonable and ok. All this can easily be field/stray effect induced in a complex station wiring-situation. If you have only one, individual, linear power supply (with earth-minus-GND on PE) backdoor coupling may get even more critical. High permeability CM (Common Mode) ferrite chokes (in 13.8V DC plus/minus) will easily saturate. Plus-amp and minus-amp will be different, because the GND (GND K3/ Earth PE ) will carry the return current difference! The worst configuration is to use one common Power-Supply-BUS for several TRX (daisy chaining, forming ground coupling loops ). TRX with an internal PS ( mains operated TRX) are typically better decoupled, causing less RX EMI backdoor input. Hopefully you have now a better understanding for trying to de-noise your station! ------------------------------------------ -----Urspr?ngliche Nachricht----- Von: elecraft-bounces at mailman.qth.net Im Auftrag von Morgan Bailey Gesendet: Mittwoch, 9. Juni 2021 02:27 An: Ray Cc: Elecraft Betreff: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 I went to a radio store to see what all the hubbub was about the FTDX10. I came prepared to test the radio. After having downloaded the manual and reading it through 3 or 4 times getting the menus, setting, knobs, filtering, general settings well in my head, I went to the store and turned one on for about 2 solid hours. I was so upset with my K3S/P3 costing over 6K$ being shown up by a $1700 radio. Granted it does not have all the bells and whistles that the Elecraft had but for a great receiver, it blows the K3 away with band noise, and electrical noise mitigation. I found the receiver to be much quieter over all and with no harsh roar constantly as the K3S has. The Pan Adaptor was way easier to use and adjustment to 5khz wide was a S&P dream to operate with an adjustable notch and contour peaking or nulling functions continuously variable for best reception. I went home and got my money back from Elecraft, $9879, they had it for over a year, and once it was in my account I ordered sight unseen and untested both FTDX101MP and D models. The MP came first. I had the D sent to the factory to install the extra 300hz cw filter. Putting the K3S/P3 on an A/B switch with the MP, the difference was astounding. I immediately listed the K3S/P3 and sold it within an hour. It went out the next morning to UPS and I have had no regrets. Both my son, NS0R, and I operated the Yaesu's in multiple contests. This was the first time in my life that we could hear stations that we could not work. Having the Yaesus was an absolute game changer for me. The VC tune is the money. This last WPX cw we increased our score by a million because we could hear stations that the K3 was deaf to. The Band noise and intermittent electrical noise in the city was easily managed by the FTDX101MP. The K3S could not even come close to this performance. Simply put the FTDX10 and the FTDX101MP/D just have better receivers, due to the noise mitigation, lower internal noise, easier to listen to for long periods, and features like the adjustable notch and contour controls coupled with the VC tune and remarkable DSP, width and IF shift controls...it is just not a little bit better, it is atleast a magnitude better. Running SO2R on a city lot with cramped antenna space is not a problem. They are clean and no phase noise/composite noise is detected on transmit in the other radio on receive. I have them side by side. I have given 2 or 3 presentations on Zoom to explain how I use the rig and the great noise mitigation that It can do. When you push a button or turn a knob on these radios, something happens. They are not there for display. FTDX101MP and D---The best radios I have ever owned or operated. 73, Morgan NJ8M On Tue, Jun 8, 2021 at 6:55 PM Ray < wa6vab at gmail.com> wrote: > > > Like the Old Saying?? > If you cant Hear them You cant Work them???. > That is WHY that is a $1000.00 Radio. > Good Luck Hunting the DX?? > > Ray WA6VAB K3 > > > From: Don Wilhelm > Sent: Tuesday, June 8, 2021 4:35 PM > To: Richard; Elecraft > Subject: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 > > Richard and all, > > I have a friend who bought a K3s and then afterward bought an IC-7300. > He is a weak signal CW type of guy and reports that there are many > weak signals that he could copy on the K3, but were non-existent on the IC-7300. > > His reason for buying the IC-7300 had to do with possible "portable" > operation.

One of the Problems with the 7300 is generally not the radio, it is the operator. The 7300 has a pretty hot front end and using Attenuation well will make that radio shine. It has a really good DSP but you have to get into the menus to make it sing. Maybe someday there will be a CIV in port to make the 7300 really sing with the KPA500/kat500. The KPA 1500 has a CIV port and works well with a 7300. Yes, the audio of the 7300 is great. I do not use full breakin because I don't enjoy the constant hash/noise in the headphones. My general setting is semi with 30 to 50 msec delay. Essentially the KTA/KAP500 makes most any rig into a 500 watt transceiver---fully automatic. Once the cables are set up, the Kat/kpa detects the freq and does the band switching. Setting up the KAT for the frequencies before turning on the amp, once this is done the system is bomb proof simple operation. I am sure you are enjoying it. 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a breadboard tuner loading a 160 meter inverted L with 1000 watts.

I set it up with KAT500/KPA500 the way it is recommended by Elecraft. Using a tuner cable from IC7300 to power and provide key information to KAT500. First a word about my operating style - I like to operate with the filters open unless I have QRM problems. Even while contesting, the narrowest filter I tend to use is 500Hz. Before the contest started, I loved the sound from the IC7300. It had the cleanness that I associate with SDR radios - Mercury, Anan, Hermes, etc. From prior usage of direct conversion SDRs I knew to expect ADC overload and how to deal with it using attenuation. After the contest started, the IC7300 was trash. It just could not deal with the wall to wall signals. Tons of artifacts, AGC pumping. I tried narrower filters, etc. Absolutely bad. I had never experienced anything like this on the K3. It sure incentivized me to fix the K3, which I did and sold the IC7300 in January. The good news about the 7300 is that the demand is so robust that I only lost a little in the purchase and resale.

Unlike straight keys and bugs, cootie key (sideswiper) sending is almost universally heavily weighted: the time between dits and/or dahs is less than the duration of a dit. My guess is that this particular rig's debounce(?) processing routine could be having trouble interpreting that keying characteristic. (I once had a PicoKeyer that had a peculiar problem with straight key input above a certain speed, later fixed in firmware.) BTW, heavily weighted code can be perfectly readable to CW operators, may even be preferred under some propagation conditions or noise, whereas software decoders may have a problem with it. (RBN & fldigi decoders seem to have a problem interpreting more heavily weighted sending.) IOW, don't automatically blame the key/operator for poor sending. It would be useful to mechanical key users if modern rigs (hint: K4) had an option for varying the parameters in the debounce (or whatever) routine to suit various characteristics of bugs, sideswipers & straight keys. It is not uncommon for a key to work fine with one rig and produce keying glitches on another. Hoping to be using my 100+ year old Bunnell Double Speed cootie to key a brand new K4 at some point... 73, Drew AF2Z On 06/09/21 09:58, Louandzip via Elecraft wrote: > > >>>>rig will not key properly with a sideswiper key.

I own a?YAESU?FTDX101MP?(?SW/FW upgrade April 2020 ) since 1 Year and am very impressed by the high performance (I do SSB , also QRO CW; ragchewing/ DXing/ Contesting). This unit YAESU is partly even better than Tx / RX K3S, but not for QSK (relays chattering) . I would like to bring the following,?unexpected findings?-should get fixed a.s.a.p.- to your attention (or did I overlook something?): 1. Voice Messages?(e.g. CQ) ?can be recorded e.g. in SSB and CW. Bacon Mode (automatic ,?interval repeat) is only possible in CW not in SSB?, very impractical. 2. Incoming signals like QSOs cannot be recorded by the TRX directly. 3. The TX PWR Meter should read PEP not average. 4. 60m (5MHz) there is no sharp preselector available (VC Tune). ?It is also not possible to activate VC Tune on 12m, 6m. 5. RX: IPO to AMP1 to AMP2 is about a 10dB difference each step (20dB range) , Input RX Attenuator is correct with -6, -12, -18 dB 6. S-Meter Calibration 160m to 6m is not always real as (IARU Definition) S9=-73dBm or 50uV/50Ohm. Yes, below S9 there are -3dB steps per S-Unit, above S9 meter indication is correct as shown 7. The band scope needs different sensitivity settings for viewing RX and own TX signals. If optimized for RX, you will see a completly distorted/ overloading signal in TX mode ! ? ? 160m to 40m: ?real S9 (AMP1) is more like S 7.5 on the meter, with IPO more like S 4.5 e.g. on 40m ? 20 to 6m: real S9 is about S9 (AMP1) on the meter ? Knowing about this I can live with it, easily. On the low bands the S-Meter is not very generous. A much more critical issue for some RX denoising applications is ? Tricky Antenna port selection , accessibility to Input RX1 and RX2 individually not possible (diversity or local QRM reduction by phasing?) ? There are 3 Ant. Ports. ? There is a RX1 out and RX2 out port, obviously only , individually selectable via menu ? Normal Configuration: T1 is TX?and?RX Port-> measuring the RX signal attenuation between T1 (AMP1 , ATT 0dB, VC Tune on) and e.g. RX1 out: It varies, from 160 to 30m?15m ?from -6db/-9dB, ?on 12m it is suddenly +5dB, on 10m there is 0dB. On the low bands there is a considerable signal loss! ? Special RX Ant. Configuration: port One (#3) can be configured e.g. as RX on 3 only , while T1 is?only?transmit ? Configuration R3 (RX only: AMP1 , ATT 0dB, VC Tune on), T1 TX only. Measuring the RX signal attenuation now between RX only import and e.g. RX1 out: -10 dB on 160m, 80m -3dB, 60/40/30/20m -5dB, 17m -7dB, 12m +6dB, 10m +2dB. The mostly relatively sharp frequency band selection (VC Tune) is clearly visible. ? Problem/Dilemma?with using an external RX phasing/ QRM Eliminator, there is now a missing function of routing the Main (TX) /RX Ant 1 Signal safely through to an RX outport (as in K3S). In FTDX101MP it is either RX all on Ant 1 or all RX on R3. ? The phasing unit NCC1 with me has 2 channels: A noisy main Antenna, B noise local noise pick-up by a 1m diameter magnetic broadband loop. The S/N improved, vector combined output port signal must go to the Transceiver RX input port ( e.g. R3). ? Therefore the safe routing through of the main antenna (only Rx function ) is badly missed here. ? Envisioned external solution: Order/Installation of a separate, ?Modular Receive Antenna Interface for Transceivers DXE-RTR-2? in front of the FTDX1001MP I also own a?Elecraft K3S?and did some?EMI?(Electromag. Interference) coupling experiment?into the power supply?(PS)?port.?This is another, aside from antenna port,?important EMI port and?potentially causing uncontrolled RX coupling. The?effect is often overlooked.?Conducted EMI -on the PS-?of TRX (?Transceiver)?results in?backdoor coupling?, if e.g. using external 12V (13.8V DC) external PS in a station. Investigation:?Elecraft?K3S?( minus on chassis ground and grounded by terminal (stud)?to station ground => risk of loop formation with PE protective earth): Lab-Testing in a well-controlled?coupling experiment?(TRX Antenna terminated with DL 50 Ohm ,?12V Battery operated-20 dB choked off, EMI injected capacitively into TRX plus, minus on GND ) ? ? one can show?S3 on the S-Meter on?80m?for already some 20mVpp CM voltage ( 12V DC plus/minus input of TRX). ? In the same test on?20m?it takes just 30mVpp to reach S8 We have seen over?100mVpp?induced on the 13.8V DC supply voltage in a K3S?experiment 28MHz, 60W into Dummy Load 50Ohm. Using a?MDS-clamp (EMC Test 30M-1GHz, --CISPR 16-1-3--, applicable to only on cable connection on K3S) test on the DC supply line resulted in 76dBpW ( about 40 micro Watt @28 MHz). This test is a "simple system configuration substitute" for a radiated test. An anechoic chamber was not available. >From this one can estimate the?100W PA?shielding/filtering efficiency?to be about?62 dB?[10xlg(60W/40uW)].?This is not unusual, rather reasonable and ok. All this can easily be field/stray effect induced in a complex station wiring-situation. If you have only one, individual,?linear?power supply?(with earth-minus-GND on PE) backdoor coupling may get even more critical. High permeability?CM (Common Mode)?ferrite chokes?(in 13.8V DC plus/minus)?will easily saturate.?Plus-amp and minus-amp will be different, because the GND (GND?K3/ Earth PE ) will carry the return current difference! The worst configuration is to use one common Power-Supply-BUS for several TRX (daisy chaining, forming ground coupling loops ). TRX with an internal PS ( mains operated TRX) are typically better decoupled, causing less RX EMI backdoor input. Hopefully you have now a better understanding for?trying to de-noise your?station! ------------------------------------------ -----Urspr?ngliche Nachricht----- Von: elecraft-bounces at mailman.qth.net Im Auftrag von Morgan Bailey Gesendet: Mittwoch, 9. Juni 2021 02:27 An: Ray Cc: Elecraft Betreff: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 I went to a radio store to see what all the hubbub was about the FTDX10. I came prepared to test the radio. After having downloaded the manual and reading it through 3 or 4 times getting the menus, setting, knobs, filtering, general settings well in my head, I went to the store and turned one on for about 2 solid hours. I was so upset with my K3S/P3 costing over 6K$ being shown up by a $1700 radio. Granted it does not have all the bells and whistles that the Elecraft had but for a great receiver, it blows the K3 away with band noise, and electrical noise mitigation. I found the receiver to be much quieter over all and with no harsh roar constantly as the K3S has. The Pan Adaptor was way easier to use and adjustment to 5khz wide was a S&P dream to operate with an adjustable notch and contour peaking or nulling functions continuously variable for best reception. I went home and got my money back from Elecraft, $9879, they had it for over a year, and once it was in my account I ordered sight unseen and untested both FTDX101MP and D models. The MP came first. I had the D sent to the factory to install the extra 300hz cw filter. Putting the K3S/P3 on an A/B switch with the MP, the difference was astounding. I immediately listed the K3S/P3 and sold it within an hour. It went out the next morning to UPS and I have had no regrets. Both my son, NS0R, and I operated the Yaesu's in multiple contests. This was the first time in my life that we could hear stations that we could not work. Having the Yaesus was an absolute game changer for me. The VC tune is the money. This last WPX cw we increased our score by a million because we could hear stations that the K3 was deaf to. The Band noise and intermittent electrical noise in the city was easily managed by the FTDX101MP. The K3S could not even come close to this performance. Simply put the FTDX10 and the FTDX101MP/D just have better receivers, due to the noise mitigation, lower internal noise, easier to listen to for long periods, and features like the adjustable notch and contour controls coupled with the VC tune and remarkable DSP, width and IF shift controls...it is just not a little bit better, it is atleast a magnitude better. Running SO2R on a city lot with cramped antenna space is not a problem. They are clean and no phase noise/composite noise is detected on transmit in the other radio on receive. I have them side by side. I have given 2 or 3 presentations on Zoom to explain how I use the rig and the great noise mitigation that It can do. When you push a button or turn a knob on these radios, something happens. They are not there for display. FTDX101MP and D---The best radios I have ever owned or operated. 73, Morgan NJ8M On Tue, Jun 8, 2021 at 6:55 PM Ray wrote: > > > Like the Old Saying?? > If you cant Hear them You cant Work them???. > That is WHY that is a $1000.00 Radio. > Good Luck Hunting the DX?? > > Ray WA6VAB K3 > > > From: Don Wilhelm > Sent: Tuesday, June 8, 2021 4:35 PM > To: Richard; Elecraft > Subject: Re: [Elecraft] A Clarification: IC-7300 vs FTDX10 > > Richard and all, > > I have a friend who bought a K3s and then afterward bought an IC-7300. > He is a weak signal CW type of guy and reports that there are many > weak signals that he could copy on the K3, but were non-existent on the IC-7300. > > His reason for buying the IC-7300 had to do with possible "portable" > operation.?

I get no blurring listing to the side tone or listening on another rig while transmitting with the MP. I know you've also complained about how your side tone sounds.? Mine does not sound like a pure sign wave, but sounds very similar to actual signals heard over the air. Of course actual signals are not pure sign tones, either at their origin or coming out of the RX. (phase noise, non-linearities, and all that...)

Be sure to be aware of its limitations before you buy it. For example, the FTdx101MP has three show-stoppers (for a CW op like me), despite it's impressive numbers in the Sherwood table: - Poor QSK performance (the clicking keying relay cannot be disabled, same problem as the IC-7300) - No CW sidetone output on USB Audio CODEC-- cannot record both ends of your QSOs (a contest requirement in some contests) - Mouse wheel is not supported for fine tuning or RIT (I think). K4 supports this very well As for comparing the K4 to the K3, despite the K3's "superior" numbers in the Sherwood table, the K4 SOUNDS so much better than any K3. The K4 audio is just SO CLEAN compared to the K3, which makes a big difference when a pileup calls. That quality is not captured by any subjective measurement. The narrow DSP filters (down to 50 Hz) also seem to work so much better in the K4 than the narrow 250 or 200 Hz crystal filters in the K3 -- no ringing. 73, Bob, N6TV On Mon, Jun 7, 2021 at 7:34 PM Doug Person wrote: > Sadly, I've decided to give up waiting for the K4.

Mr. Brown accumulated graphs published by the ARRL Lab, which are interesting, yet fail to prove the point - mostly, I am told, because the problem involves a DIFFERENT TYPE of noise, which ARRL Lab Chief Allison told me was not being measured, although it had plans to do so in the future. Thus, these claims are essentially anecdotal hearsay with several ops merely repeating what others have said. Without serious technical substantiation, these claims are somewhat reckless with undue chilling effect on owning and using Yaesu and other brand radios, as if Elecraft is all good and without fault. I was truly impressed and caught off guard when Mr. Wayne at Elecraft admitted its transmitters are using old-school technology and could stand much improvement, along with the rest of the crowd - a frankly humble and forthright statement which earned my respect. I live in a fairly large metropolitan area with a lot of other hams, and no one is complaining about noisy transmitters from any brand. This seems to be an obsession of a very few hams who enjoy mounting the soap box. I wish everyone would be as careful and as measured expressing their take. as Mr. Wayne. ? ??

Gwen was asking whose *radio* was to blame. And "hey, your radio seems to be putting out some pretty strong interference on the harmonics, can you fix that?" isn't a personal attack. The answer might be "no, I have no idea how or why it is", though. But, regardless of how "dirty" a radio is or isn't, it's reasonable to ask someone to turn the power down when they don't need it -- it can overload receivers, it can amplify any noise the radio is putting out, and it takes up that spectrum in a wider geographic area than is needed.

The ordinary ham should be able to tell when his/her rig is out of spec. The ordinary ham should be able to operate his/her rig correctly. That is just no longer the case. There are a lot of folks out there that don't even know how a repeater works at the most basic of levels. They are operating HF rigs with no understanding of how they work, and no understanding of what limits they need to maintain. They create a mess on the air, and should be told about it. Nicely, but told non the less. It is far better to have a fellow ham tell you you have an issue, than have the FCC tell you... Speaking of the FCC, I don't remember the FCC turning over responsibility for signal quality to the manufactures of radios, absolving the operator of all responsibility... It is the operators job to make sure he/she is operating their radio correctly, and within tolerance, period, end of discussion, the operator is responsible. If he/she can not tell there is a problem, than that ham should not be allowed to transmit... There are dirty transmitters all over, and they meet FCC specs... How can that be you might ask yourself? In a lot of cases, the operator is not knowledgeable in how to drive the transmitter properly, or that low voltages feeding the transmitter can cause issues, or that triggering ALC in FT8 causes issues, there are any number of settings the Amateur can screw up, and the rig meets FCC specs... So no, it is not "out of line" to let someone know their transmitter is spraying crap.

How > can that be you might ask yourself? FCC Rules include numeric limits for harmonics. The Rules include a provision that a transmitted signal shall occupy no more bandwidth then needed for the method/mode of transmission. As a member of the Standards Committee of the Audio Engineering Society, we used clauses like this so that we didn't have to cover every possibility. The Rule essentially says, you've got to be as clean as a well designed, well operated product/station transmitting the same mode. The summary I prepared of FCC Lab measurements of the occupied bandwidth of then-current CW transmitters clearly showed that some occupied FAR more bandwidth than others. At that time, the K3 was the cleanest, the FTDX5000 was the dirtiest. My process was simple -- ARRL sent me the data in electronic form, I plugged into a spreadsheet (actually, several pages of a spreadsheet, one for clicks, another for phase noise), and plotted noise amplitude vs frequency for all of them on the same graph. That report is here. http://k9yc.com/TXNoise.pdf What that Rule says is that if one manufacturer's rigs occupies 500 Hz CW bandwidth 50 dB down from the key-down signal, others should meet that performance, or at least approach it within a reasonable time for engineering departments to catch up. The K3 was introduced in 2007, first sold, I think, in 2008. Someone will correct me if needed. Chief Engineer Wayne Burdick has made no secret of what he did to achieve that, and after Flex's 6700 measured badly at the lab for bandwidth, their engineers did something to correct it (maybe Wayne's waveshaping?) and reports were that it was much cleaner. AFAIK, ARRL has not re-measured it, and I've not been able to get an owner to bring one over here to measure. As to Yaesu's SSB bandwidth -- I first learned about this hearing a couple of locals on 6M, several months apart. The first was splattering badly, calling CQ, no one answering, so I called to let him know, and suggested that maybe he was overdriving his amp. No, he responded, no amp. What rig? A current model Yaesu. A few months later, same story, except but the second guy and I knew each other. We went through every thing I could think of, first, of course, turning off his amp. My method of studying this is simply to look at the signal on the P3 waterfall. The waterfall trace of a clean signal is a vertical bar about 2-7-2.8 kHz wide, with sides that are straight lines, while one that is splattering will see horizontal breakouts from that bar on voice peaks. For general operation, I adjust my spectrum display (the top graph) for a 32 dB difference between top and bottom of the screen (42 dB for high power contests), and I set averaging for the maximum value. The result in the spectrum will show how much bandwidth is being occupied, and I can freeze the screen, move the cursor along it, read frequency and note how many dB down the sidebands are away from the carrier. The signals I've measured have sidebands that are typically only 20 dB down from the strength of the transmitted audio for about 2.5 kHz on both sides of the signal. In other words, for LSB, 2.5 kHz above the suppressed carrier, and 8 kHz below the suppressed carrier. Sadly, because there are no numbers associated with it (in the Rules), it gets ignored both by manufacturers and ARRL, who gives passing (sometimes glowing) reviews to dirty products. The same spectrum measurement can be made by switching to peak mode, accumulating peaks for a while, then killing the signal by switching off the antenna input. In peak mode, of course, the reference point for the vertical scale must be shifted. With all of this, one must learn how to set up their P3 (or other spectrum/waterfall display) to separate the forest from the trees. With averaging turned on, random noise averages out, leaving signals and electronic noise. Set the bottom of this noise to the bottom the display. This will also make signals jump out of both the spectrum display and the waterfall. The K3/P3, especially with the SVGA module, is a very nice test instrument! Most SDRs I've seen are significantly better, with greater dynamic range on screen, wider possible bandwidths, an frequency resolution that is as good or better. 73, Jim K9YC From dave at nk7z.net Wed Jun 9 23:00:30 2021 From: dave at nk7z.net (Dave) Date: Wed, 9 Jun 2021 20:00:30 -0700 Subject: [Elecraft] Gurus In-Reply-To: References: <716584982.5215873.1623203828375.ref@mail.yahoo.com> <716584982.5215873.1623203828375@mail.yahoo.com> <8fc0725c-8ed5-c2 6d-85c1-594a22ba9ed2@gmail.com> <0c73bdb3-c44d-2a70-f504-e3b4e1ad4a91@audiosystemsgroup.com> Message-ID: <02456eda-cb8f-143d-9314-94f85b437bd5@nk7z.net> Actually for this use they are...

A big part of it is knowing what you're doing, and keeping any non-linearities in the system below the level that matters. It also depends on the quality of the software running the system. 73, Jim K9YC From k9yeq at live.com Wed Jun 9 23:32:28 2021 From: k9yeq at live.com (Bill Johnson) Date: Thu, 10 Jun 2021 03:32:28 +0000 Subject: [Elecraft] Gurus In-Reply-To: References: <716584982.5215873.1623203828375.ref@mail.yahoo.com> <716584982.5215873.1623203828375@mail.yahoo.com>, Message-ID: Here, here, Julie!

I have always got to buy and try all the newest rigs and then move them on if I am not that smitten. My current rigs/keepers are a K3 (2008 vintage), TS890, Omni 6+, Orion 2 (three of those !), SunSDR2DX. Been and gone rigs include the IC7851, IC7610, TS990 (only because it got too heavy for me so I got the TS890), MB1, Flex 6600M and a number of others. I have not yet succumbed to the FTDX101 or the FTDX10 but may give one or the other a try. However, one of my main requirements is good quiet QSK so I am not sure that the Yaesu is suitable and the bandscope strikes me as horrible. I too have had a no deposit K4D on order for about two years. I intend to just let the order sit there and see if anything eventually happens and if it does I expect I will buy it !!

Thus if I note you are splattering because of too much mic gain, or whatever, doesn't excuse the person from adjusting the signal or correcting the situation, regardless of the manufacturer. It is the HAM's station creating the issue that is legally needing to correct it. Don't be offended, fix it. I have had issues with my own Elecraft radio with a circuit failure... what did I do?

The ordinary ham should be able to tell when his/her rig is out of spec. The ordinary ham should be able to operate his/her rig correctly. That is just no longer the case. There are a lot of folks out there that don't even know how a repeater works at the most basic of levels. They are operating HF rigs with no understanding of how they work, and no understanding of what limits they need to maintain. They create a mess on the air, and should be told about it. Nicely, but told non the less. It is far better to have a fellow ham tell you you have an issue, than have the FCC tell you... Speaking of the FCC, I don't remember the FCC turning over responsibility for signal quality to the manufactures of radios, absolving the operator of all responsibility... It is the operators job to make sure he/she is operating their radio correctly, and within tolerance, period, end of discussion, the operator is responsible. If he/she can not tell there is a problem, than that ham should not be allowed to transmit... There are dirty transmitters all over, and they meet FCC specs... How can that be you might ask yourself? In a lot of cases, the operator is not knowledgeable in how to drive the transmitter properly, or that low voltages feeding the transmitter can cause issues, or that triggering ALC in FT8 causes issues, there are any number of settings the Amateur can screw up, and the rig meets FCC specs... So no, it is not "out of line" to let someone know their transmitter is spraying crap.

To me, quality, usability, simplicity, update ability, cost-effective use are more important. Not the numbers. Rob owns his preferences, is not influenced by manufacturers and to me does a fantastic job of reviewing (I use different sort order for my picks at times) and because of Wayne, Eric and their phenomenal team... yes, you can say I drink Elecraft.

Bill ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of Al Lorona Sent: Tuesday, June 8, 2021 8:57:08 PM To: Elecraft Reflector Subject: [Elecraft] Gurus When this subject appeared last week I had composed a reply but then slept on it and canceled it the next morning, as I probably do 80% of the time. In this my second attempt, let me say that I've always been amazed at the power wielded by Rob Sherwood. Thousands of hams hang on his latest tests. If he deems a new radio exceptional in some way, that can mean many millions of dollars for a manufacturer. And yet, if there were no such thing as gurus on the web and at places like Dayton expounding about how Brand A is better than Brand B, how would you answer the questions, "Do I like this transceiver?," and, "Is it any good?" You'd probably get on the air and use it, and decide that way. But we constantly have gurus telling us that Brand A is the 'best' which horrifies us if up until now we liked Brand B better. Against our personal experience we flip-flop and say, "Gee, I used to like Brand B, but Brand A must be better because the gurus say so." Yet, there will always be guys who'll be tortured owning a transceiver that has the 2nd highest dynamic range, or the 3rd best distortion. Never mind if they can't actually hear the differences. It's how a rig *sounds and feels* during actual operating that's most important. Not the numbers. For instance, Wes made a comment about his tuning knob, and although some of you might have laughed at that... it's darned important! That's the kind of thing I'm talking about. Here's my opinion on ranking receivers by 2 kHz 3rd order dynamic range: almost any modern receiver has enough dynamic range to make this ranking more and more meaningless as time goes on. Sherwood himself has said that 90 dB or above is plenty enough. To understand why, see this post from 2016 by one of the old guys on this reflector: http://elecraft.365791.n2.nabble.com/K3-The-Way-We-Rank-Receivers-long-td7623639.html Lastly, if you've been enjoying your rig for years and then hear someone else complain about a flaw you weren't even aware of, don't panic. There are a million reasons why his concerns might not involve you in the least. Above all, have fun.

How "clean" (or otherwise) is his signal on your RX, with no antenna connected, and all the RX attenuation switched in. Perhaps also fit a well screened dummy load to the rig's antenna port(s) Also disconnecting just about everything else except the power (and put some ferrite on that!) All that should greatly reduce the level of his signal that your radio "see's" to manageable proportions. Even turn the RF gain down too if needed. If he's not splattering as much or at all, then it is likley your RX is being overloaded. If it sounds just as bad, and splattering just as wide, then likely it's his end. Regards to All.

I got very depressed when I saw that my K3S had harmonics only 20db down on most bands when measured by Tiny SA and its telescoping antenna. It was not being overloaded and in fact I measured similar results when feeding a dummy load. Then I went outside the shack at a distance from the antennas and found that the harmonics were 40dB down or better. Evidently when measuring inside the shack I was getting RF leakage directly through the front panel of the rig.

When he gets on 40m, I hear him on 2 other bands via harmonics. He splatters all over 40 so there's no reason for me to even have my rig turned on when he starts transmitting. I can't tell if it's a bad radio on his end or just front end overload on my end. It's frustrating to try to do a bit of CW and find that I can hear him almost as well on 15m as on 40 and 20. I haven't checked 10m, but my guess is I'll hear him there, too. I talked to him about it, and he basically blamed it on my radio's insufficient rejection. It's a KX3.

I also don't use the built in antenna. I use a tap and attenuator combination. I am also using a non clone device, as opposed to a clone device. Some clones don't have the internal shielding. Here is a compare to a clone vs a non clone: https://www.youtube.com/watch?v=I5IzLAGgKg0 Here is an interesting video showing both the strengths, and weaknesses of the tinySA. A compare of the tinySA to an HP 8921A SA: https://www.youtube.com/watch?v=xFtF2AYT0iQ For the price, and if one is careful, and aware of how to use the tinySA, you can gain a lot of knowledge for around 100 bucks. I am half tempted to buy one, and add a tap to my output coax, add power, bring it to a very low input level, and just keep the tinySA on all the time I operate, as an alarm that I might have an issue. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

That depends on whether you are talking about RF frequency harmonics or harmonics of the modulating audio frequency. There is a plague of stations producing FT8 audio harmonics. The problem is not helped by people insisting that the cure is proper ALC adjustment. While there may be rigs that cause audio harmonics because of incorrect ALC adjustment it's far more likely that the clipping that causes these harmonics happens in the audio stages long before ALC is applied. Transmitting a clean signal is the responsibility of the operator not that of the rig manufacturer or software application provider.

An amateur operator designated by the licensee of a?station is to be?responsible?for the operation of that station. Refer to ?2.201 of the FCC Rules,?Emission, modulation and transmission?. It is the ham that holds the station license and the designated operator of that station that is responsible for all emissions from that station.? This is regardless of the brand or model of equipment being used. Reading the manual and operating the equipment as specified by the manufacture is absolutely mandatory for any good operator. Using excessive levels or power is not a good candidate for a good operator and thus leads to signal degradation. The FCC no longer evaluates or test ham radio equipment.?? Each manufacturer submits the required documentation to the FCC for approval.? In doing so they are attesting that the brand / model does meet the FCC requirements. ? {I have observed an instance where approval was granted but independent measurements confirm the particular brand / model did not meet the requirements.?? In a different occasion, the company / person performing the tests said "oh, that's good enough" when indeed the equipment did not make the required measurement values.} Splatter is just that, splatter.? It is not a harmonic. "A?harmonic?is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st?harmonic, the following?harmonics?are known as higher?harmonics."?? Thus if one transmits a CW signal then the 2nd harmonic is 2x the fundamental frequency.? Thus 3.562 MHz has a 2nd harmonic at 7.124 MHz.??? Or if one transmits an FT-8 signal at 735 Hz then the 2nd harmonic is 1470 Hz. Hams do make mistakes and can often mis-adjust their radios, deliberately, unintentionally, or unknowingly.? Advising one in a friendly and informative means is just good practice.?? I don't care how expensive or how advanced ones station might be, operated incorrectly it can and will cause spectral issues.?? Unfortunately many new hams aren't really technical and may not understand how and why certain things occur.? They have to be educated in proper station set-up and operation.?? It is up to the more experienced and more knowledgeable hams to provide this service. Don't be mislead by what I describe as "old ham lore".?? Just because someone said bla bla bla doesn't make it correct.? One must always check and verify to their own level of satisfaction or seek the advice of others.?? Or perhaps, just read the manual. The acronym for that is RTFM. 73 Bob, K4TAX On 6/10/2021 11:22 AM, elecraft-request at mailman.qth.net wrote: > Message: 1 > Date: Thu, 10 Jun 2021 04:22:25 +0000 > From: Bill Johnson > To: Dave,"elecraft at mailman.qth.net" > > Subject: Re: [Elecraft] Gurus > Message-ID: > > > Content-Type: text/plain; charset="utf-8" > > I would add, the radio operator with a license is supposed to know the requirements and operate accordingly. This includes staying with the passband of the FCC regulations. Just because a radio is FCC accepted, doesn't mean the operator doesn?t have responsibility to stay within the regulations. Thus if I note you are splattering because of too much mic gain, or whatever, doesn't excuse the person from adjusting the signal or correcting the situation, regardless of the manufacturer. It is the HAM's station creating the issue that is legally needing to correct it. Don't be offended, fix it. I have had issues with my own Elecraft radio with a circuit failure... what did I do?

Couldn't agree more. Dave said: "Here is an interesting video showing both the strengths, and weaknesses of the tinySA. I looked at the videos and said, "Okay, where are the strengths?" I spent a lot of years sitting in front of spectrum analyzers. One of the first things you want to do after displaying signals of interest is to adjust the input attenuator up or down. If you add or remove10 dB of attenuation and ALL of the signals do not change by exactly 10 dB, you have a linearity problem at that setting.? Don't use it, or if you do, understand that you are getting bogus answers. Likewise, if you have a really clean, stable source like a quality OCXO with published phase noise specs and you measure it with your SA and it looks other than that, you're measuring your SA's shortcomings.? That's okay as long as you understand them. Wes?

Steve K6UM, a neighbor at the time, contacted me and said I had bad key clicks. I was glad he did. We got on the phone, made adjustments and resolved it. Prior to that I didn?t know the default CW rise time was way too fast and that letting ALC control exciter power was a terrible idea. I LEARNED something and it was FUN. When I stop learning things and having fun, I will leave this hobby. Not likely! From the Amateur?s Code. Seems as valid today as ever. The Radio Amateur is CONSIDERATE...He/[She] never knowingly operates in such a way as to lessen the pleasure of others. PROGRESSIVE...He/[She] keeps his/[her] station up to date. It is well-built and efficient. His/[Her] operating practice is above reproach. FRIENDLY...He/[She] operates slowly and patiently when requested; offers friendly advice and counsel to beginners; kind assistance, cooperation and consideration for the interests of others. These are the marks of the amateur spirit. 73 Josh W6XU Sent from my iPad From dean.k2ww at gmail.com Thu Jun 10 15:36:41 2021 From: dean.k2ww at gmail.com (Dean L) Date: Thu, 10 Jun 2021 15:36:41 -0400 Subject: [Elecraft] Gurus In-Reply-To: <1b04e642-5ccd-1571-1f6f-3b1d5173a5df@triconet.org> References: <716584982.5215873.1623203828375.ref@mail.yahoo.com> <716584982.5215873.1623203828375@mail.yahoo.com> <02456eda-cb8f-143d-9314-94f85b437bd5@nk7z.net> <02a901d75dfe$e239e3c0$a6adab40$@n4st.com> <1b04e642-5ccd-1571-1f6f-3b1d5173a5df@triconet.org> Message-ID: looked at the videos and said, "Okay, where are the strengths?" the fact that it's $100 Not looking to wage war just stating facts The first rules of using test equipment you got to trust it... 73 all Dean On Thu, Jun 10, 2021, 15:26 Wes wrote: > Dean's making the case I thought to make.

Most often this happens at 7025 but also seen at 7035. The P5 show signals and the main RX is OK but the SUB RX is just noise and no sig. Some times just a very slight nuge of the B VFO in the HF direction is sufficent to restore sigs, but bring the B VFO down again and sub RX becomes deaf with a lot of noise again. When you tune across this edge 7025 or 7035 you can turn "ON" and "OFF" this sub RX noise. I have seen this very same effect at both M6T and when elsewhere on different SN radios. I can hear the shouts of B/Set already and antenna switching, but it's not this as in all ocasions we either had an ext antenna or loop back with filters etc. connected. I know this radio is getting on a bit old but it's got a few years left surley, hence any help re this would be much appreciated. Could this be a calibration issue? I doubt it as it is defetnaly related to the VFO(A) QSY issue. Any sugestions from the expert here much appreciated, apart from buy a new radio that is...! 73 Tony G2NF -- Sent from: http://elecraft.365791.n2.nabble.com/ From ardrhi at gmail.com Thu Jun 10 14:39:26 2021 From: ardrhi at gmail.com (Gwen Patton) Date: Thu, 10 Jun 2021 14:39:26 -0400 Subject: [Elecraft] Gurus In-Reply-To: References: Message-ID: Yes, precisely!

To add the SubRX IF output, you need to look at the holes for the coax that are next to the buffer amp - approximately in the middle of the board the holes for the coax are there - doing nothing until you use them. Then it is simply a matter of routing coax (RG174) from the holes for the coax to the left rear of the SubRX. If you want to do a really neat job of it, the board has holes for mounting a TMP connector.? I chose to use a 2 pin Molex disconnect just outside the SubRX assembly instead (since I did not have any TMP jacks available). Where you mount the SubRX IF out jack on the rear panel is an effort and a choice for the owner. 73, Don W3FPR On 6/10/2021 4:08 PM, Jeff Goldman wrote: > I am looking for any information on hooking up a P3 to the sub-receiver in a K3S.

Hi Mike, More than 15 years ago, while still living in Chicago, I bought used Elecraft transverters for 50, 144, and 220 MHz, to use with my K2. The two that I had occasion to use were unstable. A simple study of their construction made it obvious why.They were designed and built with Pin One Problems -- RF inputs and outputs are BNC fittings insulated from the shielding enclosure, as badly conceived non-solution to a stability problem lurking somewhere on the PCB, and the isolated BNCs were an inappropriately chosen band-aid. EMC guru Henry Ott talked in his seminars about "the hidden schematic lurking behind the ground symbol," and the unintended current paths that resulted from ignoring it. 73, Jim K9YC From charles.hardt at mgccc.edu Thu Jun 10 19:25:39 2021 From: charles.hardt at mgccc.edu (Charles Hardt) Date: Thu, 10 Jun 2021 23:25:39 +0000 Subject: [Elecraft] KIO3B upgrade In-Reply-To: References: Message-ID: I have the upgrade on my K3. Single USB cable that creates two virtual ports. One for rig control and the other K3 sound card. I am talking about a Windows 10 installation and operation. I have done it in Linux on Raspberry Pi, but had to watch a lot of YouTube videos to adjust audio via a Pi Terminal screen. I find windows a lot easier. In Windows you need to go in and find your serial port for both audio and rig control, just like you did with your Signal Link for rig control (I use a Signal Link with my KX3 and earlier with my K3 before upgrade). Then to adjust audio go into Windows "Setup", "Audio Devices" and adjust your audio output (Typically speaker audio level) from your computer to K3. Setup K3 to adjust your modulation level just like you did with the Signal Link. Typically levels are lower than the radio's microphone. Then adjust the audio in Windows, "Setup", "Audio Devices" as you did on the Signal Link. For audio from the K3 to the computer just increase audio (typically computer microphone audio level) until your computer program begins to react to the sound. Not sure what computer program you are using, but make sure you have selected the K3 USD sound card, typically called "USB audio codec" in your computer program. Otherwise the computer program may default to your computer sound card (Not Good!). I find windows adjustments very easy and can do it on the fly. I work NBEMS HF & VHF and that requires audio readjust going from HF to VHF and back. Getting rid of the required rats nest of wires with the Signal Link was worth it. I was banking on your experience with the Signal link, so did not go into a lot of intimate details. So if more details are needed don't hesitate to get back to me. I really like the USB K3 interface with Windows and I am sure a lot on this list will disagree with me. I have no experience in the Apple/Mac.

Maybe the RJ45, to two serial Db9 connectors isn?t really a split serial port.?? Any quick and easy guide to make the RJ45 work???

There is a plague of stations producing FT8 audio harmonics. The problem is not helped by people insisting that the cure is proper ALC adjustment. While there may be rigs that cause audio harmonics because of incorrect ALC adjustment it's far more likely that the clipping that causes these harmonics happens in the audio stages long before ALC is applied. > > Transmitting a clean signal is the responsibility of the operator not that of the rig manufacturer or software application provider. > > Andy, k3wyc > > > ------------------------------ > > Message: 2 > Date: Thu, 10 Jun 2021 13:24:04 -0400 > From: Joseph Shuman > To: elecraft at mailman.qth.net > Subject: [Elecraft] Gurus, Giving Up & Group Therapy > Message-ID: <0931F187-6D25-4ED9-B9FB-064BE15DFDC2 at icloud.com> > Content-Type: text/plain; charset=utf-8 > > Humor on this Board is sometimes misunderstood.

This includes staying with the passband of the FCC regulations. Just because a radio is FCC accepted, doesn't mean the operator doesn?t have responsibility to stay within the regulations. Thus if I note you are splattering because of too much mic gain, or whatever, doesn't excuse the person from adjusting the signal or correcting the situation, regardless of the manufacturer. It is the HAM's station creating the issue that is legally needing to correct it. Don't be offended, fix it. I have had issues with my own Elecraft radio with a circuit failure... what did I do?

Regarding Z4... there were a series of Builder's Alerts that came out with mods to be made. It's possible that yours is also a field test and/or some of the mods were not done in your version. Don W3FPR may be better able to talk to that, and to have the Builder's Alerts handy in digital form so I don't have to scan them for you. :) Anyway, Alert #5 says Z4 is supposed to be a 56 ohm resistor. I'll have to dig deeper to see what is up with Q1. 73 jeff wk6i On Thu, Jun 10, 2021 at 3:08 PM Don Wilhelm wrote: > Mike, > > Has the paint been cleared from all parts of the enclosure that contact > the 2D connectors? > If not, that could be reason for your observations. > > You might want to remove those capacitors to see if all is well without > them. > I have lots of experience with the Elecraft transverters and do not > recall that as a mod. > > 73, > Don W3FPR > > On 6/10/2021 5:37 PM, Mike Cizek W0VTT wrote: > > Greetings, > > > > > > > > I recently purchased a used XV222 that had some modifications done in the > > local oscillator circuit.

Db9/serial port problem I have read the Elecraft K3s manual, K3 manual, Expert 2K manual.. realize that I need to try to use db9..(RJ45) and have been told to use a Y connector (using the y connector I purchased from Elecraft for P3 display but I don?t use it).. and connect only two wires to Expert (ground and RXD- but NOT tXD)-and the the other Y I fed through a USB convertor. That goes to a Dell Win 10 computer which doesn?t even allow one to see comm ports in device manager. Yes I tried ?hidden devices? but never saw Comm port or LPT anywhere. Guess I might have to go back to a ?legacy computer -windows 7, or make my linux mint do it.. I do have WSJTX running fine on IC-7600, and CiV com talks to Expert 2K fine. Doesn?t work. Maybe the RJ45, to two serial Db9 connectors isn?t really a split serial port.?? Any quick and easy guide to make the RJ45 work???

This includes staying with the passband of the FCC regulations. Just because a radio is FCC accepted, doesn't mean the operator doesn?t have responsibility to stay within the regulations. Thus if I note you are splattering because of too much mic gain, or whatever, doesn't excuse the person from adjusting the signal or correcting the situation, regardless of the manufacturer. It is the HAM's station creating the issue that is legally needing to correct it. Don't be offended, fix it. I have had issues with my own Elecraft radio with a circuit failure... what did I do?

Audio levels are controlled two ways, 1, in the K3 menus and 2, in the computer operating system sound settings. The application may also have adjustments for the audio levels. At first, losing my knobs made it a little more difficult to set levels for different modes and applications, but once I got it set just right, I found that saving the configurations made the adjustments much more precise from and repeatable from mode to mode, etc. I really like the single USB cable between the PC & K3. 73 de Joe NE3R On Tue, Jun 1, 2021 at 7:39 AM Jim Leder wrote: > > I have an older K3 and have been using a USB Signalink for digital.

Message-ID: <025f01d76087$ce625040$6b26f0c0$@comcast.net> Having worked retailing amateur radios, people often ask which is best. Also often they are absolutely convinced they know the answer because their Elmer said so. When I review what someone actually wants to do with the hobby and get a sense of their budget, I can advise them. A new Ham often hasn't a clear idea what they want to do. Knowing most of what is available, there are no truly "bad radios" that would be unsuited for anyone at all. Not everyone can afford "the best". Not everyone can use the best. New operators may not even be able to manage a ton of fancier features. New Hams may not know there is more to the hobby than whatever their Elmer has locked on to (20+ years ago). Life in an HOA or a city with much RFI directs from most expensive and top of the line towards something portable. The visibility provided by a Pan Adapter function is especially important. Personally I have a KX3, PX3, KXPA100. I also own an IC 7300. My recommendations at work would tend to what I can sell of course. If someone knows what they want, they buy it. I find too that upselling the radio is not productive either. Once someone has a radio they will need antennas, feed lines, maybe a tuner, wire, rope, books, power poles, antenna analyzer - all that stuff is the really great stuff J Also, if someone gets a lot of books, they will learn other aspects of the hobby and get another radio and the cycle repeats.

Your advice is helpful. I have set the transmit delay to 15ms. I have found lots of info on using the IC7300 with the KAT500/KPA500 combination but none on using the setup that I have, ie., IC7300 exciter, to KPA500 with LDG AT-1000 Pro II autotuner. I will make sure that I don't pump full watts into LDG tuner during tuning (I will use only the IC7300 to do the tuning) or not to present a high SWR to the amp. As you know with the IC7300, I use the "tune" button on the IC7300 and it limits the output to 10 watts for the LDG tuner to go through its tuning cycles (the internal tuner in the IC7300 is bypassed when wired to the LDG tuner). I have tried to get some responses in other forums but no luck. -- Sent from: http://elecraft.365791.n2.nabble.com/ From a.durbin at msn.com Sun Jun 13 20:40:30 2021 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 14 Jun 2021 00:40:30 +0000 Subject: [Elecraft] KAT500 Tuner antenna selection stuck in #2 position Message-ID: "I cannot change the antenna selector via the front panel of the KAT500 or the utility software." What was the KAT500 mode when you observed this problem? There is a known firmware defect that may prevent enabled antennas being selected when mode is BYP. The same problem does not exist if mode is MAN and state is Bypassed. Until this is fixed the solution is to avoid mode BYP (Mode MAN and state bypass is electrically identical). 73, Andy, k3wyc From briankmaynard at gmail.com Sun Jun 13 21:25:27 2021 From: briankmaynard at gmail.com (Brian Maynard) Date: Sun, 13 Jun 2021 21:25:27 -0400 Subject: [Elecraft] [ELECRAFT] Are there any "bad radios"?

Clicks and what we have long called splatter ARE exactly the same mechanism -- intermod distortion of an amplitude modulated signal. In the case of CW, its 100% amplitude modulation of a carrier by a rectangular keying waveform. Phase noise is an entirely different mechanism. 73, Jim K9YC From lstronk at optonline.net Mon Jun 14 09:23:21 2021 From: lstronk at optonline.net (Lance HP) Date: Mon, 14 Jun 2021 13:23:21 +0000 Subject: [Elecraft] KAT500 Tuner antenna selection stuck in #2 position In-Reply-To: References: Message-ID: KAT500 mode is any mode - current mode is auto, but any mode change does not make any difference in ability to change from the #2 antenna position. haven't tried to erase all my settings and revert back to factory default settings...yet.

There is a known firmware defect that may prevent enabled antennas being selected when mode is BYP. The same problem does not exist if mode is MAN and state is Bypassed.

I've been in lots of contests where the operator is either unwittingly or intentionally putting trash on the band (there are hams on the Contesting reflector who have publicly admitted intentionally creating clicks to give themselves more elbow room), but it doesn't change the fact that there are also some pretty poor transmitters out there that were purchased by people who either didn't know it or didn't care.

Next time you have your K3 open, pull out KAT3 and preemptively remove L10 and C10, and replace with a jumper. You don't need them and they are probably messing you up at times. (Are there any other older K3 issues like this? Tell me!) I have an early model K3 that still has all of its original modules. I was having an issue where the power output was sometimes dropping to just a few watts. Running the TX calibration would sometimes fail completely with weird error messages, but if I could get it to run it would get through most of the way but always fail on 52MHz due to high SWR (over 2). With a dummy load or a matched antenna, SWR was over 2 also in normal operation. Of course, this low power situation would magically correct itself after some poking around, though the 52MHz high SWR was consistent. I finally decided that I wanted to do some 6m operating and I used the KAT3 to get matched to the load. I would just operate until something finally decided to fail fully. It did. After a few hours C10 on the KAT3 blew, LOUDLY and smokily. Undoubtedly due to some crazy high voltages presented by the tuner. After some sleuthing in the Elecraft reflector I found the C10/L10 filter issue being well discussed. Pulling them out and jumpering solved all my issues. With the K3, anyway. :) This filter was not included in the KAT3A. If you have one of those, you're good. If you want to know more about the history of this filter it's easy enough to find in the email archives. :) Hope this helps - jeff wk6i -- Jeff Stai ~ WK6I ~ wk6i.jeff at gmail.com RTTY op at W7RN Twisted Oak Winery ~ http://www.twistedoak.com/ From haljr.massey at gmail.com Mon Jun 14 17:59:12 2021 From: haljr.massey at gmail.com (Hal Massey) Date: Mon, 14 Jun 2021 15:59:12 -0600 Subject: [Elecraft] Are there any "bad radios"?

Hams should be *held responsible*, but should not be *condemned*, if their stations are causing problems and they're not aware. Hams should inform each other politely if their stations are causing problems, and should fix their stations if so informed. Hams may condemn each other if they knowingly continue to operate a station that is causing problems. You can't always point a finger at the radio, station configuration, or operator in isolation, and it's not generally helpful anyway. "What constitutes a problem?" is still a pretty open question though. 73, Julie On Mon, Jun 14, 2021, 18:01 Hal Massey wrote: > Aren?t the radios inanimate objects?

Clicks and chirps were quite evident on the bands.? Some were gradually culled out as those radios were taken out of service, but I think it was not until the 90s that we saw a great reduction in those radios. This was not operator faults, but deficiencies with the radios. In modern times, many hams overdrive their radios resulting in bad performance, and that can be termed operator problems, assuming he is using a clean radio. Those who intentionally produce clicks or turn the mic gain up so high as to splatter should be ashamed.? One can make plenty of contacts in a contest with a clean signal. I have operated a K3 in crowded band conditions - Field Day - and there were only a few stations that could not be worked. Now, if each radio had a hand to slap the operator in the forehead when he was transmitting a dirty signal, that might bring an end to this problem.? In the meantime, it is up to other operators to call out dirty signals. Straight Key Night were some drag out their 1950s and 1960s rigs may be an exception to this "rule". 73, Don W3FPR On 6/14/2021 7:41 PM, Mark via Elecraft wrote: > Those that think there are bad radios now don?t remember those of 60s.

There is a learning curve with the radio new nomenclature to understand on the new platform. I'm an old dog and there are few new tricks. So to the point. I connected the K4 to my PC with the supplied type B USB cable. I expected to find a new Com Port on Device Manager. However I found under Other Devices, 2 Dual RS232 icons. When looking at the Properties tab, there is no driver. I can find no reference on the Elecraft website or on the internet about which driver might work. I'm sure I'm missing some simple step, but I guess I don't understand why their would not be a driver and further, how would I direct my software to the Dual RS232 port?

When it's set to ON, it may induce gain and S-meter variations under certain noise conditions. (Otherwise, it does an excellent job of suppression large impulses due to appliance power switching, etc. In fact we call it the "Sherwood Pulse Detector" here at Elecraft Hq, because the original idea came from Rob.) For now I'd recommend setting it to OFF. We're working on a solution. 73, Wayne N6KR From jd at ko8v.net Wed Jun 16 08:44:03 2021 From: jd at ko8v.net (Joseph DeVincentis) Date: Wed, 16 Jun 2021 12:44:03 +0000 Subject: [Elecraft] K4 Rackmount Message-ID: I've decided to rack mount my K4. It looked like there were two options. I went with SNS Engineering (www.snsengineering.com) and I very happy with that decision. I placed the order and shortly thereafter, got a call from the owner (Ashok, N6NAC). He gave me some insight on the design of the rack mount as well as how familiar he is with the Elecraft line. I'll say Ashok really does know what he is doing. He sent some drawings over, we chatted about the drawings, and it all looked good. The mount shipped and a few minutes after it was delivered, he called to offer his help one on one if I needed it. That is customer service. The rack mount requires replacing the right-side panel, so it has mounting holes for the bracket (the left side uses the currently existing handle screw holes). The new right-side panel looks and feels identical to the OEM panel. If it weren't for the additional mounting holes, you would not be able to tell the difference between the two, right down to the feel of the powder coating. The finished work is first rate. All mounting hardware is stainless. The front rack panel is beast of an aluminum panel. Once it the radio is in the mount, it feels rock solid. The look and feel are very professional and makes the desk cleaner (my desk has space for 2 5U racks on it). Once Elecraft gets the remote software going, the entire radio system is going into a about a half size rack, and I'll relocate my operating position to a more comfortable place in the house. I will probably use a K4/0 or K4/0 Mini when they become available. When I do the final rack, I will probably need some additional racks for other equipment. He can do about anything you need. He has a full shop and a couple of CNC machines to do the work. I won't hesitate to call on him. I have no relation to Ashok, other than being a very satisfied customer. He was an pleasure to deal with and has lots of good information. 73, Joe, KO8V From calvin at kr5e.com Wed Jun 16 11:15:56 2021 From: calvin at kr5e.com (Calvin) Date: Wed, 16 Jun 2021 10:15:56 -0500 Subject: [Elecraft] K3/0 Remote Message-ID: <57753560-484f-82b3-55ae-06882aa4087f@kr5e.com> Anyone have a K3/0 Remote Control they would like to sell?

Message-ID: Hi, In the KX3 for Field Day department, we plan to use it for the GOTA station for phone on HF. (Yes, will have antennas not on top of each other and bandpass filters on ALL radios.) Would be great to setup with a headset and foot switch. Last weekend, I used my KX3 barefoot on 6 and with a transverters-store.com transverter (also barefoot) for 2. 6m antenna was 2 elements about 15 ft above the ground and 2m antenna 6 elements at 10 feet above the ground. I worked a couple of contacts on 2m phone with the headset. Later, when I tried to use the headset for phone on 6, seemed like I was having a feedback problem. Cabling was the stock cabling that comes with the Heil Pro 7 headset and a footswitch. Monitor was on and set to 4. So, ALC didn't indicate anything at the normal level (60), and increasing it very abruptly caused horrible sounding audio. (Yes, acts like positive feedback.) I have a small electret mic on a 1/8 plug thing I bought some time ago from the computer store. (Meant at the time for adding mic to laptops.) I have a 1/8" audio extension cable for it. I plugged that in instead of the headset mic and it seemed to act normally. Is this purely an RF from the TX antenna getting into the mic audio problem or is it something else? Best practice to avoid this problem? On my todo list: - ask here - look at KX3 schematic to see if it has RF ingress mitigation on the mic jack - ask Heil - unplug the Heil mic element and gator clip my cheap electret mic on instead and try on 6m in driveway with identical antenna/mast/radio setup - look for or assemble an RF filter to inline with the mic jack (tough to do with this little time before field day) Thanks and best regards, Drew n7da ps. Other than this, KX3 was great in the VHF test. Worked great with the transverter on 2 and was a lot of fun running barefoot with the sporadic E opening Saturday afternoon & evening.

In-Reply-To: References: Message-ID: I'd believe it! I've gotten weird noise artifacts before that were actually "the monitor level is so low that the DAC is running out of bits". Mine showed up most obviously as harmonics in the sidetone. Try adjusting the monitor level in CW mode and see if you hear your issue at the lowest levels but not higher. If you do, you could get an inline attenuator for the headphones so you can run the AF gain and monitor levels high enough to sound better.

They are uncomfortable to wear for an extended period of time. I do have RFI issues with them when running full power on HF SSB. I have an older Heil headset - not sure which model - came with a used IC-7700 several years ago. It plugs directly into the back Of the K3s. I get better audio reports with it than the Yamaha?s. All fairly subjective. I do have RFI issues with the Heil headset also. I am lucky enough to have used one of Bob?s mixing desks and a B-3 he had modified during a repair. He?s not a hack.

Part of the APP connector is inside the K3. You may be able to salvage the contact blade (be certain it is seated all the way), but if you cannot, I recommend you download the assembly instructions for one of the XV series transverters to see how those APP connectors are installed using #14 gauge wire - the alternative is to order new contact blades. You can optionally glue a new locking pin in place once you have completed the repair, but if you use "Superglue" between the halves of the connector, that is seldom necessary. 73, Don W3FPR On 6/17/2021 6:54 PM, Rich wrote: > [K3} - K3 Powerpole > > The positive (red) Powerpole plastic on my K3 broke while pushing it back on > my desk. > Has anyone replaced the plastic covers without taking the K3 apart?

An important advantage of a boom mic headset is that it maintains a constant distance from the mouth -- loudness varies as the square of the distance, so it minimizes variations in loudness. The only shortcoming of the Yamaha set that I've run into is the fragility of the cable. I'm hard on cans, and I've had to replace them twice over about 12 years. 73, Jim K9YC From jim at audiosystemsgroup.com Thu Jun 17 20:28:55 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 17 Jun 2021 17:28:55 -0700 Subject: [Elecraft] Heil Pro 7 headset with KX3 - RF feedback?

My latest with the FTDX101MP is Heil RED Pro 7 (with red contest cartridge) . Right after the TRX audio output and mike input I always have a Ferrite N30 7 windings on each shielded cable. The monitor (listening to SDRs e.g.) plug/shielded cable is blocked right at the headset with a small N30 core. The 1.5m long shielded audio cable goes to my station notebook. All is several times ferrite blocked and separated by a suitable audio transformer before going into the computer audio out. I also own a Bose Aviation A20 Headset (over 1K$) with super active noise cancellation. Guess what, into the spiral shielded cable I had to put a 10cm ferrite rod ( Hi permeability, positioned toward electronic battery unit ) to finally kill all RFI. It goes without saying mike cable and phone cable are both ferrite core blocked right at the transceiver K3S. In my Club CW Contests and FD I use Bose Quiet Comfort 25 (260$ around at that time?) - with N30 ferrite at the radio... I needed to build an extra audio attenuator to get to my wanted very low audio level. My other older Heil (Headset) systems have all ferrite cores towards the radio. Bose is most comfortable in my opinion...

Elecraft has a long history of Pin One Problems, which are a well known cause of RFI. I first alerted Wayne to this at least 15 years ago. Elecraft is not unique in the regard -- the last time I was at Dayton, several years ago, EVERY radio on display in booths that I was able to look at had obvious Pin One Problems. The following links were written nearly 20 years ago. Pro audio has mostly cleaned up its act.

That's acoustic interaction of the earphones with your aids, and depends on the placement of the mics in the aids. Mics for the aids are picking up their own amplified sound, because the acoustic space around the ear is modified by the presence of the earphones. In sound systems, we call that feedback. It makes sense that different headphones would interact differently with aids, depending on the construction of both. My XYL uses aids where the mics are outside the ear. She doesn't use headphones when she's wearing them. 73, Jim K9YC From rick.nk7i at gmail.com Fri Jun 18 15:04:25 2021 From: rick.nk7i at gmail.com (Rick NK7I) Date: Fri, 18 Jun 2021 12:04:25 -0700 Subject: [Elecraft] Heil Pro 7 headset with KX3 - RF feedback?

Any issues? The important (and killer) issue with Bluetooth is latency when you try to run CW. The delay makes it impossible to send with any form of bug, paddle, or straight key. The delay is also be problematic if you try to monitor yourself on SSB. When I was doing live sound for large crowds outdoors, I heard very professional announcers slow down and stop talking when they heard themselves coming back through the system 100 msec late. There are (at least) two forms of BlueTooth. The one for shorter distances (lower power) has less latency than the other. Both would be a killer for CW, but the shorter one might not be too bad for monitoring our own transmission on SSB. 73, Jim K9YC From w6jhb at me.com Fri Jun 18 16:10:25 2021 From: w6jhb at me.com (James Bennett) Date: Fri, 18 Jun 2021 14:10:25 -0600 Subject: [Elecraft] Heil Pro 7 headset with KX3 - RF feedback?

I have an IC-705 (my K-line is packed in storage currently) and have tried Bluetooth with it. Using several different BT headsets (Bose QC, Apple Air Pods, Avantree) it was an utter failure on CW. However, I recently got an Srhythm NC35 noise cancelling headset from Amazon. It works wonderfully on CW - zero latency to be detected. I operated several times in the CWops Wednesday night get togethers (high-speed CW) and THIS bluetooth headset was perfect. That being said, I am unaware what version of BT the ?705 is using. But, one shouldn?t completely abandon the technology - it can work in certain circumstances.

However, the headphone plug-insertion detect circuit may involve an IC downstream that could include a schottky diode junction -- a potential way a very strong signal could be rectified right at the radio end of the cable. We're looking at that. If the cable is not very well shielded, and the TV station is *very strong*, I can imagine modern physics just barely covering this situation. It would help if the headphone cable was about the length of an end-fed dipole at the station's frequency. As for the K4 chassis itself: It's very well sealed (far better than the K3/K3S).

I usually use a smaller, lower wattage rig, but decided recently to use the K3 portable. I've used the K3 for POTA activation three times before this week -- but all on SSB. Today, I used FT8. I first was on 20M and everything was quite normal. Then I switched to 30M, and I was hearing nothing and friend who I was texting who lives fairly close to the park wasn't seeing my CQs. I had the MODE set to DATA. The friend suggested I switch to USB mode, and lo and below I started seeing signals on my screen and completed several QSOs. I had used DATA mode on 20M and it worked FB. I also later used DATA mode on 40M. Why didn't DATA mode work on 30M? Is there some setting where I have to declare USB or LSB for each band separately for DATA mode? All of this seems very strange to me. I used my K3 before for data modes in the shack, and I don't recall this issue. Any suggestions would be greatly appreciated. -- 73 de Carl N8VZ -- Sent from: http://elecraft.365791.n2.nabble.com/ From pvandyke1953 at gmail.com Sat Jun 19 20:52:56 2021 From: pvandyke1953 at gmail.com (Paul Van Dyke) Date: Sat, 19 Jun 2021 20:52:56 -0400 Subject: [Elecraft] 12 meter CW, anyone?

There's output attenuation in the app, per-app output volume (on some operating systems), and master output volume. If it can be toggled or there are separate jacks, are you using headphones or line-out? Have you tried the other? If you've got an audio interface with a hardware output gain knob, have you checked the settings on that? Have you checked the cables and connections, and perhaps tried another cable? If you're using SSB instead of DATA mode, have you checked the COMP and TX EQ settings? (DATA mode avoids this problem.) Have you tried transmitting some other computer audio, like a plain sine wave of good volume? This would isolate the app, output attentuation, or per-app volume. Have you tried transmitting some plain mic audio in the same mode? This would isolate the app, computer, or interface. 73, Julie On Sun, Jun 20, 2021, 13:10 wrote: > > > My K3S occasionally does not put out any power when transmitting FT8.

With headphones set for stereo, you'll hear it in your right ear, with the main RX in your left ear. Once it's on, a long push on the SUB button puts you in Diversity mode, for which you need a second antenna and an input for it. Perhaps study of the rest of manual might be a good thing. Over the years, I've owned ICOM, Yaesu, an Ten Tec rigs, and their user interfaces have all differed radically from each other. The Elecraft UI is, by far, the best of them all, but you have to RTFM to understand it. 73, Jim K9YC From dick at elecraft.com Sun Jun 20 15:28:35 2021 From: dick at elecraft.com (Dick Dievendorff) Date: Sun, 20 Jun 2021 12:28:35 -0700 Subject: [Elecraft] New K3 user...

The process is mentioned in the KRX3 manual and at the end of the K3 manual where the various menu items are described. Hold the CONFIG button (the button is labeled "Menu") located near the top left of the front panel. Rotate VFO B until you see "KRX3" in the bottom line of the LCD screen. Rotate VFO A to Ant = ATU or Ant = bnc depending on your use of a 2nd antenna (mine says ANT = ATU). Leave the menu (by tapping the MENU button again), then turn on the SUB by tapping the SUB button on the bottom right of VFO A. the "SUB" icon (surrounded by a box) should appear beneath the two VFO frequencies on the LCD screen. Adjust the main and sub receiver volumes with the concentric RF and AF gain knobs. You can decide whether to hear the sub and main mixed into both headphones by the L - MIX - R menu item, mine is set to A b so that I hear the main and sub receivers simultaneously, one in each ear. Other possible problems are that the sub receiver may be switched to a different antenna, to check this, HOLD BSET (to the top right of the LCD screen), then set the ANT to the appropriate antenna for VFO B and make sure that the RX ANT is as you expect it to be. 73 de Dick, K6KR -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jim Brown Sent: Sunday, June 20, 2021 12:06 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] New K3 user...

It is set per-band. DATA A is usually the correct sub-mode for FT8. This uses the USB mode. On 30m, you were likely using the AFSK A mode, which is similar, but uses LSB mode.

My KPA500 was back to the factory in March and had this mod installed. That didn't help much in the "robust" department, because my amp went south almost immediately after its return. Apparently the PIN diodes D8, D9 and/or R7 have failed. I received many replies to my question on this forum from others who had the exact same issue. The symptom is recieve signal is attenuated about 20 dB when Operate is engaged; normal in Standby.

Been a ham since 1970. For some strange reason, my interest in amateur radio always peaks at the bottom of the sunspot cycle. No, I don't understand it either :). Lately, I've been playing a lot with CW & QRP radios. Got a uBITX "kit" from India. In quotes, because it was assembled and tested, you just mount the boards in the case. Then a "QCX+" kit from Hungary - this was a real kit, you solder in the parts. I discovered that I *really* like electronic QSK ( aka full-breakin CW ). The QCX+ does it really well. But it's only one band. I built it for 40M, but during the day, the action is mostly on 20. The uBITX is multi-band, but does not do QSK. What to do? I investigated converting the uBITX to full-break, but that turns out to be a very big deal. As in "Nobody's done that yet". ...So yesterday I pulled the trigger on an Elecraft K2 on Ebay. Waiting with bated breath for that box in the mail. It's an early serial number - 00845. It seems that a lot of changes took place over the years - and Elecraft doesn't show a manual for it - their download site only shows the manual for "Rev B" PC boards. I see that they still have some parts and accessories for this unit - and the SSB module is not too expensive. - Jerry KF6VB From n6kr at elecraft.com Tue Jun 22 14:29:51 2021 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 22 Jun 2021 11:29:51 -0700 Subject: [Elecraft] K4 Field Day configuration notes Message-ID: <92496386-CC72-4015-AECA-ABF8AB5E9BDD@elecraft.com> Field Day stresses most radios (and their operators) more than usual. That's part of the "fun" :) Beta release 18 of the K4 software provides an "RX Dynamic Range Optimization" menu entry that should be turned ON for Field Day, even if you normally leave it off. This configures the A-to-D converter for best dynamic range. (Turning it off may slightly improve sensitivity. At present the setting applies to all bands; in a future release it may be settable per-band.) We strongly recommend installing release 18 if your current software is older. Previous releases had only the equivalent of turning the menu entry off. Another setting you'll find useful is MENU:RX Auto Attenuation = ON. This allows the K4 to automatically and temporarily reduce front-end gain on a per-receiver basis if extreme signal conditions exist. Such conditions are presently indicated by the "+" in the S-meter's "+60" label turning to magenta. The indication will be more prominent in the next beta release (19, due in a day or two, most likely). You can also control front-end gain manually when you see the OVF (or "+") indication. 73, Wayne N6KR -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.

I'm not an expert on the K2, just a die hard fan. Others will advise you on the upgrade(s). I'm pretty sure the upgrade "kits" are available from Elecraft. That said, once you're satisfied with your upgrade you can go all the way a purchase the complete, current kit from Elecraft and put that together. Hardly anything beats that for fun.

Armed with that documentation, you can physically examine the K2 to see which upgrades have been installed. Physical exam is the only way it can be done. Elecraft still has the upgrade kits.

When a fan blower from a big amp is going right underneath the rig, there is a limit to gain and compression adjustments that can be made to get rid of that much background noise. Plus a room with hard floors makes the problem worse (although I do have throw rug down). This is the type of environment where downward expansion shines. Phase Inversion: Perhaps I wasn't clear: For some reason with my setup, this Heil GM5 mic produces negative deflection on a power meter when using AM. Example: you set the AM carrier at 25 watts, expecting modulation to 100 watts, but instead you observe 25 watts deflecting to 15 watts. I don't know why that occurs, but I do know that flipping the Invert phase switch solves the problem.

Here's what I have learned, specifically about chassis, from long experience: * If you want your case to act as a shield, do NOT put RF current through it. If you want your VFO to be stable and not shift when you touch the case, do NOT put RF current through the case. * If you don't want your tube radio to hum, do NOT put AC filament current through the chassis or case! Once upon a time, I built a linear with 4 sweep tubes in an ARC-5 cabinet. There was a hum on the HV - no amount of filtering would cure it. It turned out that the hum was caused by sharing a single ground return for the HV and the filaments. IIRC those filaments pulled 10A of ac current, which caused an ac voltage drop on the ground return. The fix was to use a separate ground for the AC filament current. And I had to lift all the individual filament pins off the chassis. Somebody gave me a Heathkit OM-1 oscilloscope. There was a hum on the trace. It went away if you shorted the input. No amount of filtering would cure it. The cause was - again - AC current being passed through the chassis. And the chassis was aluminum, held together with self-tapping sheetmetal screws. Dissimilar-metal corrosion caused resistance which the AC current turned into AC voltage. Whups, gotta go.

Directional, excellent sound reproduction. Bill K9YEQ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Tim Tucker Sent: Thursday, June 24, 2021 1:36 PM To: Elecraft Reflector Subject: Re: [Elecraft] K4D #150 I use a Heil GM5 mic, with the gain and compression adjusted so my lips have to be almost touching the windscreen to drive the rig. When a fan blower from a big amp is going right underneath the rig, there is a limit to gain and compression adjustments that can be made to get rid of that much background noise. Plus a room with hard floors makes the problem worse (although I do have throw rug down). This is the type of environment where downward expansion shines. Phase Inversion: Perhaps I wasn't clear: For some reason with my setup, this Heil GM5 mic produces negative deflection on a power meter when using AM. Example: you set the AM carrier at 25 watts, expecting modulation to 100 watts, but instead you observe 25 watts deflecting to 15 watts. I don't know why that occurs, but I do know that flipping the Invert phase switch solves the problem.

Color me happy :). I just ordered the SSB adapter. My first impressions: The UI is a little cryptic - a general weakness of things with small displays and few knobs/switches/buttons, but really not too bad. I've already got most of the buttons memorized. Receive is nice & quiet. When I disconnect the antenna, there is very little internal hiss. The AF gain control was scratchy at first, but quieted right down with a little use. Had my first QSO with it - with Don Huff, W6JL. Don gave me a good report. Even though I was only running 10 watts. I notice that the band noise changes tone between "CW" and "CW R". Could that be symptomatic of a misadjusted BFO? Also WWV is a little off - switching from CW & CW-R changes the beat note. Looking forward to getting into this; Ebay just yielded up a GPSDO ( GPS-disciplined oscillator ) which is supposed to emit 10Mhz accurate to a tiny fraction of a Hertz. I'll want to start inspecting the radio to see what needs updating. - Jerry KF6VB From gthornton at thorntonmostullaw.com Fri Jun 25 16:09:41 2021 From: gthornton at thorntonmostullaw.com (George Thornton) Date: Fri, 25 Jun 2021 20:09:41 +0000 Subject: [Elecraft] OT: Nano VNA In-Reply-To: <349017784.995928.1624623476977@webmail4.networksolutionsemail.com> References: <8b76eeb4-2d88-e96e-9ce4-8a24cce255af@gmail.com> <6f217343-5304-ce3e-f135-cacd57324e29@audiosystemsgroup.com> <349017784.995928.1624623476977@webmail4.networksolutionsemail.com> Message-ID: Roughly in the same price range is the Array Solutions AIM UHF. In the course of my HAM career I have used a variety of analyzers. I have a NanoVNA and it does work, but its menu system is horrible and counter intuitive. In addition the use of tiny connectors is not ideal for our common N and PL 259 equipment. It also has to be recalibrated a lot more than other units and that can be a hassle. I don't completely trust it because I am not always sure I am using it correctly. My favorite analyzers were the AA series and the AIM UHF. The AA 600 I owned was a stand alone unit and it was pretty trustworthy. The AIM UHF seems to be very similar to the VNWA referenced below and was in approximately the same price range. It also worked through a computer. In the end I much prefer the AIM UHF. Although it was a bit inconvenient to have to bring along a computer, I found that in nearly every situation it was worth the inconvenience. For instance, graphing a full SWR curve along a frequency range was very helpful to analyze antenna tune. You can see exactly how the curve goes including the lowest point and you could make gradual antenna modifications to get perfect tune. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of w2xj Sent: Friday, June 25, 2021 5:18 AM To: jim at audiosystemsgroup.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] OT: Nano VNA The problem with that is it requires a computer and is apparently limited to Windows software.

Would miss it if gone for a few weeks :-) Though some thoughts: VNA's are, if calibrated and temperature stable, inherently accurate. Requirements are: Must have Log sample spacing. 2 port must have 12-term compensation. Required to normalize Port 2 Zin to 50.00 Ohm. For measurements over 100MHz, must have Arbitrary calibration capability. A way to test capability is measuring Ferrite complex permeability. An example is: https://www.kn5l.net/S21adapter/FR43-material/ Web page is in notebook style with several iterations. Final measurement under heading "FT50-43 Panel Jack Fixture." Follow link for "Calibration Process" In the example above, I predict Fair-Rite 43 material measurement, using HP E4991a with 16454A fixture (1MHz-3.0GHz), has a 2.47nH calibration error.

Test equipment has become a hobby in itself lately, for many of us I think. I hadn't thought of measuring crosstalk - that would be a method of determining 'why' a divergence of two VNA's might exist. I'm mainly interested in knowing if one exists, by how much and at what frequencies. Explaining the reason(s) for it might be something to be explored later.

I transferred all the antennas, microphones, and CW keys over from my K3 but have run into a few problems. First, I have tried transmitting in CW but cannot get the radio to transmit anything. I have tried two sets of paddles and ensured I plugged it into the correct jack. I also tried a straight key in the Key jack and the same issue presents itself. I also ensured VOX is on. Even if I manually activate transmit there is nothing transmitted. It has me thinking the Jack?s may not be turned on. I have similar issues with the PTT jack behind the radio. The switch I plugged into the jack is not activating the transmitter. I did ensure it was plugged in correctly. Finally, I have another issue with the front panel mic jack. I can key the radio from it, but the microphone I plugged in is not working. I checked and the front panel microphone is enabled in the settings. I have a CM500 plugged in to the rear of the radio and it does work when switched to rear input. Has anyone else run into something like this?

It must be wired to match your chosen microphone. Since you did not build that K2, you may not know how to get to the Front Panel.

Color me happy. I just ordered the SSB adapter. My first impressions: The UI is a little cryptic - a general weakness of things with small displays and few knobs/switches/buttons, but really not too bad. I've already got most of the buttons memorized. Receive is nice & quiet. When I disconnect the antenna, there is very little internal hiss. The AF gain control was scratchy at first, but quieted right down with a little use. Had my first QSO with it - with Don Huff, W6JL. Don gave me a good report. Even though I was only running 10 watts. I notice that the band noise changes tone between "CW" and "CW R". Could that be symptomatic of a misadjusted BFO? Also WWV is a little off - switching from CW & CW-R changes the beat note. Looking forward to getting into this; Ebay just yielded up a GPSDO ( GPS-disciplined oscillator ) which is supposed to emit 10Mhz accurate to a tiny fraction of a Hertz. I'll want to start inspecting the radio to see what needs updating. - Jerry KF6VB From k2asp at kanafi.org Sat Jun 26 14:22:16 2021 From: k2asp at kanafi.org (Phil Kane) Date: Sat, 26 Jun 2021 11:22:16 -0700 Subject: [Elecraft] K2 initial impressions In-Reply-To: References: Message-ID: <0c10cb04-1c4f-1ba6-59e4-7e16a25798a3@kanafi.org> On 6/26/2021 10:47 AM, Bob McGraw wrote: > Frankly, signal strength means little to me.?

When you get to jumper W6, know that you can and should adjust the bandpass filters for maximum RF voltage there. On a new build, be aware that the most common problems are soldering, misplaced or incorrect components and diode orientation.? If you suspect diode orientation problems, refer to the Parts Placement Diagrams in the back of the manual to check them. Another common problem is inadequately stripped and tinned toroid leads.? You should be able to see a bit of tinned lead on the top of the board. 73, Don W3FPR On 6/26/2021 4:58 PM, VA1CQ wrote: > Don, > > A logical suggestion.

All of the gear looks and functions as new. The KX3 has every option except the KXPD3 keyer paddle. The KXPA 100 received new finals at Elecraft in 2019 and has been used less than ten hours since that time. A set of manuals is included, the latest versions are of course available on the Elecraft website. The equipment consists of: KX-3 160m - 6m Transceiver with the following internal options: KXAT3 20 watt ATU KX3-2M 2 meter module KXBC3 NiMh Internal charger with Real Time Clock KXFL3 Dual Bandwidth Roofing Filter Also included with the KX3 are the following two items: KX3-PCKT Cable set MH-3 Hand mike I also have the following for sale: PX3 Panadapter with cables KXPA100 with internal KXAT100 tuner also with all cables My firm prices are: KX-3 equipment ?. $1550 Shipped in the US KXPA100AT ?. $1250 Shipped in the US PX3 ? $575 Shipped in the US I prefer to receive payment via PayPal the cost of which is included in the above prices. I would also very much like to sell the entire station to the same person. The price for all the equipment sold as one lot is $3200 Shipped in the US.

In doing my due diligence, I've stumbled upon a dilemma. It appears the KPA1500 will track bands for ICOM using CI-V. I am currently using CI-V to auto switch antennas, so that ties up the radio's CI-V port. The antenna box (Bandmaster V) is using BCD to control the relays at the box (RCS-10). It seems the KPA1500 supports band control via BCD. My question - can I parallel connect the BCD outputs from the Bandmaster V to both the relay box AND the KPA1500? Or alternatively, parallel the output the ICOM's CI-V port? 73 Kelly - N0VD From pvandyke1953 at gmail.com Sun Jun 27 15:08:34 2021 From: pvandyke1953 at gmail.com (Paul Van Dyke) Date: Sun, 27 Jun 2021 15:08:34 -0400 Subject: [Elecraft] 80 Meter Net Sunday Night In-Reply-To: References: Message-ID: Hey ... was in the Field Day and ducking storms and forgot to post to the List Tonight ..

I don't see anything wrong with the RF Detector circuit. The signal on D9 is only 84 mV when measured with the RF Probe. So I pressed forward with signal tracing. It appears I have an RF signal at the Transmit Mixer (0.274 V) and Buffer (1.45 V) outputs. But at W6 (Band-Pass Filter output) and T-R Switch #1 output, I have no measurable signal (0.5 mV). Further, DC voltages check out on diodes D1 to D7 on the RF Board and all diodes are oriented correctly on the board. I also noted that the Driver and PA transistors have correct voltages and seem to switch on keydown. Tuning the Band-Pass filters had no effect no effect on improving output power.? Power remains at 0.1 to 0.2 watts. I was able to tune L8 and L9 for the 30-metre filter to improve reception on that band to receive some RTTY, WWV and a CW signal. During the build, I swapped location of the two 20-metre trimmer capacitors (C21, C23) with the location for the 10-metre trimmers (C44, C46). In reversing these, it's possible I damaged one or more of the trimmers. But, if I did, I don't think this would cause the no power output problem on any band that I'm experiencing.

A major highlight was having slices of pizza (and Corona[s], with lime) delivered to my operating position in near darkness by amused family members. For the first half I used a KX2 at 10 watts, with a couple of different 4? whips. Not that my QTH is treeless; I was just evaluating QSO rate of electrically short whips vs. full length antennas. For the second half I used a K4 and a 7 amp gel cell. I stuck with 10 W, but used a 16? vertical. (Yes, QSO rate went up.) You may recall that Elecraft was launched on a Field Day weekend over 20 years ago. Back then our goal was simple: to design all of the accessories into the rig, in that case the K2. Now, doing FD with the K4, it?s a whole new ball game. The large display, dual panadapter, mini-pan, and dual receive make my style of hunt-and-pounce operation a joy. It?s what I wanted all along and didn?t know it. At 10 W, SSB contacts in particular are more challenging. But the rig creates more opportunities. While waiting to repeat a call of one station, I can engage the sub RX and scan farther up the band to find the next one to call. My only regret is not hanging out with the K6SRA gang this year. Already dreaming up new antennas for next year! 73, Wayne N6KR ---- elecraft.com From kl7uw at acsalaska.net Sun Jun 27 21:47:09 2021 From: kl7uw at acsalaska.net (Ed Cole) Date: Sun, 27 Jun 2021 17:47:09 -0800 Subject: [Elecraft] Fun on 14.074 today Message-ID: Well it started out troubleshooting why I had bad SWR with the new 20m dipole I put up.? And (of course) it was the RG-58 coax jumper I had used for umpteen years without trouble.? So realizing that my broken tri-band yagi might not be broken, I tried 20m and it tuned up nice with my KXPA100/KXAT100.? SWR was about 3.9 without tuning (very old trap yagi). So I listened to the FD a bit on SSB then tuned in FT8 on 14.074 (wholly Moses, the bandwidth was clobbered with signals).? So with only 100w I tried a few contacts.? In the last two hours of FD, I made 11-contacts (and messed up 12).? Best was working BH2UEZ in PM08 (China) with my yagi pointed East. worked: BC,UWA,SV,SCV,UT,WY,LAX, and OR.? About an hour at 100w the amp started faulting (surmised over-temp and lowered power to 30w, finally running my k3/10 barefoot).? Also checked 15m and 10m for tuning (all good).? Maybe the "old girl" still has some kicks! Other news I am building a MRF 1K50H LMOS HF/6m amp.? Cited at 1200w, it will replace my Harris ch.2 TV amp that I use on 6m.?

Among other things, that modern software can easily link computers from multiple stations in a club setup. That's important, because each station can see the other's log. We work QRP battery with a single K3, and are often weak at the other end of the QSO. When logging computers are linked, each station sees the QSOs we've already had on 20 (easier copy) when we work them on 40, 80, and 15, so it's rare for them to need a fill if they are networked. It was disappointing to see that so many hams fail to continue their ongoing education by learning new stuff, like modern logging software. I'll be 80 in the fall, a ham since age 15, BSEE in 1964, and I still try to learn new stuff every day. BTW - I do LOTS of FT8 and MSK144 on 6M and FT8 on 160M, our QRP CW operation was all CW. W6JTI and I made a combined 680 QSOs. I've been using K1JT's digital modes for more than ten years. So have a bunch of OTs I know. And when I was taking a break from CW, I worked FT8 on 6M (along with K6EU, our primary VHF op) to pass out our rare grid (CM86). That VHF station ran high power and was not part of our QRP FD operation from a contesting point of view. Tom and I were simply lighting up our rare grid. 73, Jim K9YC On 6/28/2021 1:34 AM, David Wilcox via Elecraft wrote: > One of the hams running our CW tent used his old favorite logging program and brought along an old DOS computer to run it??.

Set up portable at 7am Sunday in Bay View Park in Milwaukee (right next to Lake Michigan). Spent about 3 hours using only 3 watts and managed to work about 75 stations across 40, 20, 15 & 10. Thank goodness for 15 being open. This was my first time using the AX1. Worked flawlessly out of the box. It does help to elevate the counterpoise wires so it helped to have a few bushes near my park bench. Spent the rest of FD before and after the park operation using a 35? wire up maybe 7 feet at most, strung outside the window of our AirBNB. Overall 141 Qs in about 7 hours. No where near my best effort but for running 3 W in the park and 15 watts to a suboptimal wire antenna it was one of the most satisfying contests I have had in awhile. With QRP/suboptimal antennas (as with most other things in life - like waiting for a K4D) you have to be patient. QSOs take time but they can be more satisfying than rotating the beam and turning on the KPA500, thus blasting your competition out of the water ;-) - Yes, I do have a K4D on order but if it had arrived in early 2021 I would not have purchased the KX3. And BTW the KX3 works just fine with a KPA 500 - ?only? 200 watts but works better for me that the old IC737. I find it amazing that you can re-invent your love of a hobby just by getting some new gear. (First new radio in 26 years). This FD reminded me of my first FD in 1979 using an HW8 and a 135? wire and just how much fun it was (and still is) to have someone come back to your call. 73 Jay N9CIQ From jerry at tr2.com Mon Jun 28 11:00:37 2021 From: jerry at tr2.com (jerry) Date: Mon, 28 Jun 2021 08:00:37 -0700 Subject: [Elecraft] K2 BFO In-Reply-To: <18E133CB-4040-42B9-8E36-C7B4DE1FA4F9@gmail.com> References: <18E133CB-4040-42B9-8E36-C7B4DE1FA4F9@gmail.com> Message-ID: <386593fb3d5d5cfd7cf3a9367c869f3e@tr2.com> Hello all, I note that my new ( to me ) K2 is not well set up on the BFO for the narrow CW filters.

I used this antenna on 40-6 meters with my upgraded K3, KAT500, and KPA500. I do not have HOA constraints, but I live on a small urban lot that is topographically challenged (steep slopes). The Zero-Five build quality and materials are excellent. Customer support is great and very responsive. Conceptually, the flagpole and monopole antennas are similar in that they use a 4:1 UNUN, require radials, and are not resonant when used as a multi-band vertical. SWR on all bands is typically less than 4:1 and the KAT500 easily matches it. Zero-Five uses an UNUN made by Balun Designs which are well made and robust. If installing a flagpole antenna is your only option, Zero-Five is a good choice. Have you considered a vertical on a tilt base that you can easily lower. I like the Zero-Five but I am currently using a DX Commander all band vertical (40-6M). It is ?stealthy? as it uses a black fiberglass collapsible pole (33 feet in length). It could be installed using a tilt base. I like this antenna because it is simple, is resonant (less than 1.5:1 on all bands), and does not use traps, UNUNs, etc. I used the same radials I installed for the Zero-Five and have had good results with it. Good luck. 73 Howard/WX7HS > On Jun 28, 2021, at 09:53, James Bennett via Elecraft wrote: > ?Wondering if anyone on this reflector is using their K-Line rig (especially the KAT500) with one of the ZeroFive Flagpole antennas?

My radial field is putrid - just a couple of quarter-wave wires for each band, because our house lot in south Florida is 1/5 acre, and I have 7.5 kV 3-phase power lines running down two sides of the property. However, it (and its predecessor, a Zero-Five 20m quarter-wave vertical) has held up very well in the salt air, and performed beautifully. In fact, I also have a large coil that allows me to tune it on 630m. When using it without the 630m coil, the internal tuner matches up beautifully on all bands from 80m through 10m. I've always been very impressed by the construction of these antennas - beautiful machine work, precise fittings, and very durable, so I highly recommend them from that perspective. I augmented my radial field with three 8 foot ground rods pounded into the sand angled downward away from the base, plus I ran some #000to the ground screen under the swimming pool. Typical ground resistance at resonance is about 25 Ohms. I'm not subject to HOA/CC&R restrictions, and our city does allow amateur radio antennas to a certain extent (60 ft max for the first tower, oneadditional tower at 40ft), but considering we're right on the Atlantic coast, that's pretty understandable. (And, Florida Power & Light is in the process of moving all of the HV and household feeders underground, so really, at this writing, I have 3-phaseHV lines along only one side of the property, and those might have been de-energized at this point as well; I will perform another round ofnoise measurements when we return in November, but the noise was about S9 this winter before they started working on the lines).

The dial calibration data is stored in EEPROM and is what is used to display the dial frequency.? The EEPROM is loaded by running the CAL PLL menu routine with the counter probe in TP1. Yes, C22 must be adjusted just before running CAL PLL or CAL BFO. I use WWV which transmits 500 or 600 Hz tones on alternate minutes.? Using SSB, align those tones with the 500 and 600 Hz markers on your audio spectrum analyzer to assure that you are tuned correctly. Once you get the KSB2 option installed, you can enter the BFO frequencies suggested in the manual and then proceed to do a more precise dial and BFO calibration. The DAC steps for the BFO limits the precision that you can achieve, but 10 to 20 Hz is achievable. 73, Don W3FPR On 6/28/2021 2:16 PM, jerry wrote: > Hi Don, > > ??

The one that works the best for YOUR needs. Generic may not do contests well; contesting logbooks may not do every day well. Some play well with other code; some play well with hardware; some don't do either. Some cost money; some are free.? Some are just crap-ware...

Good luck with extending your own user interface.? I am sure there are contest logs listed somewhere on the web.? Not only would you get a list of CW ops who contest, you could also grab their details to fill in more fields.? Then scan that list with the partial call you copied.? Even brute force search algorithms would be fine. ?? As far as slicing and dicing data Perl, awk, and sed can do wonders with extracting, and formatting individual fields.? Plus they are already available on your OS.? A two line script with any of them can do what you want. ?? The killer app for contesters seems to be N1MM.? I think you will have more fun writing your own since you know exactly what you need and what you like.? Building your own app should not be shamed. ??? GL & 73, ????? Kevin.?

When the HOA was formed, I ran for the Board, got elected ( not > much competition ), and made d*mn sure I was on the architecture committee. That's where I was when we moved into a brand-new condo in California in1988. At the time the "Board" was the developer, and I scored a meeting with their VP-engineering. Spoke to him engineer-to-engineer and got approval for several VHF/UHF antennas on the roof. When the Board was turned over to the owners I made sure that I was on the new Board and I drafted a Memorandum of Ratification that covered more antennas including a long wire with secured access to the roof. The other two Board members were too dumb to do anything but approve it. Even after I was off the Board in a power play the antennas stayed there until we moved in 1999. Note - I have no intention of serving on a Condo or HOA Board again even for a sack of gold..... 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From louandzip at yahoo.com Mon Jun 28 18:30:10 2021 From: louandzip at yahoo.com (Louandzip) Date: Mon, 28 Jun 2021 22:30:10 +0000 (UTC) Subject: [Elecraft] K-Line / ZeroFive Antennas In-Reply-To: References: <88DA8B7E-35EF-4C2C-BC25-8B0BC7862C2A@me.com> <4BECCE10-860C-405B-821E-E07ABBEB2372@me.com> <49393640.2408783.1624904825774@mail.yahoo.com> Message-ID: <1272695632.1152117.1624919410324@mail.yahoo.com> One thing to consider with these (and any) antennas is FCC-19-126A1.?

But there are some excellent choices out there, and many are free or very low cost, so experimentation is probably the best teacher. Like you said, some have tons of features that you may not have even dreamed of. You may find that some of those features are indispensable once you have tried them, and others are useless to you. If you enjoy writing and maintaining code, more power to you! Playing with some of the free software might still be worthwhile just for the inspiration. On the other hand, if you're tired of rolling your own, you can probably find something that meets your needs and then some. I've found that different situations (e.g. DXing vs Contesting) call for different tools, so I use more than one, but that's a personal choice. Here's some logging software features that are important to me...they may not be important to you... #1) must allow me to record all of the information I care to log, and not force me to record stuff that I don't #2) must automatically capture any information from #1 that is provided by the radio or other peripherals (e.g. time, data, frequency, mode, callbook lookups, etc.) without me having to manually enter it 3#) must support import/export of data in standard formats 4#) must support reporting of things I'm interested in knowing from my log (canned reports and/or database queries) 5#) must be in active development and support (e.g., to support new contests, changes to DX entity lists, bug fixes) Some very nice to have items (bordering on essential for me): #6) integration with Logbook of the World #7) integration with DX spotting networks #8) integration with digital modes (e.g. software for RTTY, PSK, MSK, etc.) Other useful features: #9) integration to control antenna rotators #10) customizable colors, fonts, etc. #11) free or low cost I choose the software that works best for me, and then get the platform that supports it (Windows in my case). Others may value a specific platform (Mac/Win/Linux) more highly and look for software that can run on it. To each his own. I?ve settled on DXLab DXKeeper for general use and DXing, and a separate contest-focused logger for contesting (usually N1MM, but I occasionally use others specifically written for certain contests). I export ADIF files from the others after each contest and import them to DXKeeper as my ?master log?. I've also found the N3FJP loggers to be a good value for the money. I've dabbled with others as well on Windows, Linux, Android, and iOS - they all have their advantages. Good luck in your quest !

And (of course) it was the RG-58 coax jumper I had used for umpteen years without trouble.? So realizing that my broken tri-band yagi might not be broken, I tried 20m and it tuned up nice with my KXPA100/KXAT100.? SWR was about 3.9 without tuning (very old trap yagi). So I listened to the FD a bit on SSB then tuned in FT8 on 14.074 (wholly Moses, the bandwidth was clobbered with signals).? So with only 100w I tried a few contacts.? In the last two hours of FD, I made 11-contacts (and messed up 12).? Best was working BH2UEZ in PM08 (China) with my yagi pointed East. worked: BC,UWA,SV,SCV,UT,WY,LAX, and OR.? About an hour at 100w the amp started faulting (surmised over-temp and lowered power to 30w, finally running my k3/10 barefoot).? Also checked 15m and 10m for tuning (all good).? Maybe the "old girl" still has some kicks! Other news I am building a MRF 1K50H LMOS HF/6m amp.? Cited at 1200w, it will replace my Harris ch.2 TV amp that I use on 6m.? When new amp is running I will sell the Harris with the HP 50v PS I have been using (bought a new Meanwell RSP-3000-48 to replace it).

Among other things, that modern software can easily link computers from multiple stations in a club setup. That's important, because each station can see the other's log. We work QRP battery with a single K3, and are often weak at the other end of the QSO. When logging computers are linked, each station sees the QSOs we've already had on 20 (easier copy) when we work them on 40, 80, and 15, so it's rare for them to need a fill if they are networked. It was disappointing to see that so many hams fail to continue their ongoing education by learning new stuff, like modern logging software. I'll be 80 in the fall, a ham since age 15, BSEE in 1964, and I still try to learn new stuff every day. BTW - I do LOTS of FT8 and MSK144 on 6M and FT8 on 160M, our QRP CW operation was all CW. W6JTI and I made a combined 680 QSOs. I've been using K1JT's digital modes for more than ten years. So have a bunch of OTs I know. And when I was taking a break from CW, I worked FT8 on 6M (along with K6EU, our primary VHF op) to pass out our rare grid (CM86). That VHF station ran high power and was not part of our QRP FD operation from a contesting point of view.

Set up portable at 7am Sunday in Bay View Park in Milwaukee (right next to Lake Michigan). Spent about 3 hours using only 3 watts and managed to work about 75 stations across 40, 20, 15 & 10. Thank goodness for 15 being open. This was my first time using the AX1. Worked flawlessly out of the box. It does help to elevate the counterpoise wires so it helped to have a few bushes near my park bench. Spent the rest of FD before and after the park operation using a 35? wire up maybe 7 feet at most, strung outside the window of our AirBNB. Overall 141 Qs in about 7 hours. No where near my best effort but for running 3 W in the park and 15 watts to a suboptimal wire antenna it was one of the most satisfying contests I have had in awhile. With QRP/suboptimal antennas (as with most other things in life - like waiting for a K4D) you have to be patient. QSOs take time but they can be more satisfying than rotating the beam and turning on the KPA500, thus blasting your competition out of the water ;-) - Yes, I do have a K4D on order but if it had arrived in early 2021 I would not have purchased the KX3. And BTW the KX3 works just fine with a KPA 500 - ?only? 200 watts but works better for me that the old IC737. I find it amazing that you can re-invent your love of a hobby just by getting some new gear. (First new radio in 26 years). This FD reminded me of my first FD in 1979 using an HW8 and a 135? wire and just how much fun it was (and still is) to have someone come back to your call. 73 Jay N9CIQ ------------------------------ Message: 5 Date: Mon, 28 Jun 2021 08:00:37 -0700 From: jerry To: Jay Grokowsky Cc: elecraft at mailman.qth.net Subject: [Elecraft] K2 BFO Message-ID: <386593fb3d5d5cfd7cf3a9367c869f3e at tr2.com> Content-Type: text/plain; charset=US-ASCII; format=flowed Hello all, I note that my new ( to me ) K2 is not well set up on the BFO for the narrow CW filters. It's fine for the 1.5kHz one, but the audio passband is too high for all the narrower ones - so I cannot "spot" tune. If my sidetone is set to say 600Hz, it's on the lower slope of the audio peak. It seems to be straightforward to adjust the BFO per filter with the CAL FIL function. With a tablet running a spectrum analyzer, I can pull the audio spectrum right down to where it needs to be, no problem. HOWEVER, when I try to save it, I get "INFO 230" which means that the frequency counter is not connected to the BFO. And the passband doesn't stay changed. Is it true that the rig will refuse to save the BFO setting unless it can measure the BFO frequency? My radio came to me without a frequency probe. I do have one on order from Elecraft. I also have enough junk to make one. A hunk of RG316, some dupont connectors, an 11pf dipped silver mica capacitor. But - at the moment, I really don't want to do any of that stuff. I just want to slide the audio output spectrum down to where I can get on with operating. And I'm not interested in the numerical BFO reading. Ultimately, I will set up the filters from scratch - I have the upgraded crystals AND the SSB adapter on order. Can the radio REALLY not save the BFO setting unless it can measure it? - Jerry KF6VB ------------------------------ Message: 6 Date: Mon, 28 Jun 2021 11:14:20 -0400 From: Don Wilhelm To: jerry , Jay Grokowsky Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] K2 BFO Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed Jerry, Yes, you need to have the counter probe plugged into TP2 to save thee BFO frequency. You can build your own probe - if you use #14 solid wire, it will fit nicely into the test points. Solder the 11pF right above the tip and coax up to the header on the Control Board - the shield goes closest to the left side panel. 73, Don W3FPR On 6/28/2021 11:00 AM, jerry wrote: > Hello all, > > ??

I?m moving to a new home with HOA/CC&R crap (you know the drill - happy wife, happy life) and am considering the ZeroFive 24 foot, 40-6 meter flagpole antenna. If you?ve run one of these antennas and have matched it via a KAT500, how well did it work? Did you have the KAT500 on your desk, or remote at the antenna base? These antennas have gotten great five-star reviews on eHam.net , so that seems to indicate that these very expensive verticals might be a viable solution.

Made up a counter probe from a hunk of rg316, crimped a couple of dupont female clips onto the end, put them in a shell, squished a dab of hot melt glue between the pins so they couldn't short out, slipped over a bit of shrink...etc. I recently acquired a GPSDO ( GPS Disciplined Oscillator ) that is supposed to emit 10MHz accurate to a tiny fraction of a Hertz. Will be using that to calibrate the frequency counter. But for the nonce... ..

I used this antenna on 40-6 meters with my upgraded K3, KAT500, and KPA500. I do not have HOA constraints, but I live on a small urban lot that is topographically challenged (steep slopes). The Zero-Five build quality and materials are excellent. Customer support is great and very responsive. Conceptually, the flagpole and monopole antennas are similar in that they use a 4:1 UNUN, require radials, and are not resonant when used as a multi-band vertical. SWR on all bands is typically less than 4:1 and the KAT500 easily matches it. Zero-Five uses an UNUN made by Balun Designs which are well made and robust. If installing a flagpole antenna is your only option, Zero-Five is a good choice. Have you considered a vertical on a tilt base that you can easily lower. I like the Zero-Five but I am currently using a DX Commander all band vertical (40-6M). It is ?stealthy? as it uses a black fiberglass collapsible pole (33 feet in length). It could be installed using a tilt base. I like this antenna because it is simple, is resonant (less than 1.5:1 on all bands), and does not use traps, UNUNs, etc. I used the same radials I installed for the Zero-Five and have had good results with it. Good luck. 73 Howard/WX7HS > On Jun 28, 2021, at 09:53, James Bennett via Elecraft wrote: > ?Wondering if anyone on this reflector is using their K-Line rig (especially the KAT500) with one of the ZeroFive Flagpole antennas?

That reassured me that the dial was accurate enough to keep me inside the ham bands. People often instruct one to "zero beat" WWV. I fail to see how this can be done with an SSB receiver with a properly set BFO, since the carrier is then outside of the filter bandpass. Also, except during the announcement period, WWV is actually transmitting multiple "carrier" frequencies at the same time. Not going to mess with SSB a lot at this time because I have the SSB adapter on order, and I'd have to do it all again anyway after receiving that. I just calibrated the counter with the GPSDO.

My radial field is putrid - just a couple of quarter-wave wires for each band, because our house lot in south Florida is 1/5 acre, and I have 7.5 kV 3-phase power lines running down two sides of the property. However, it (and its predecessor, a Zero-Five 20m quarter-wave vertical) has held up very well in the salt air, and performed beautifully. In fact, I also have a large coil that allows me to tune it on 630m. When using it without the 630m coil, the internal tuner matches up beautifully on all bands from 80m through 10m. I've always been very impressed by the construction of these antennas - beautiful machine work, precise fittings, and very durable, so I highly recommend them from that perspective. I augmented my radial field with three 8 foot ground rods pounded into the sand angled downward away from the base, plus I ran some #000to the ground screen under the swimming pool. Typical ground resistance at resonance is about 25 Ohms. I'm not subject to HOA/CC&R restrictions, and our city does allow amateur radio antennas to a certain extent (60 ft max for the first tower, oneadditional tower at 40ft), but considering we're right on the Atlantic coast, that's pretty understandable. (And, Florida Power & Light is in the process of moving all of the HV and household feeders underground, so really, at this writing, I have 3-phaseHV lines along only one side of the property, and those might have been de-energized at this point as well; I will perform another round ofnoise measurements when we return in November, but the noise was about S9 this winter before they started working on the lines).

Just adjusting C22 is not enough for a complete job of dial calibration. That oscillator is the clock for the MCU.? The dial calibration data is stored in EEPROM and is what is used to display the dial frequency.? The EEPROM is loaded by running the CAL PLL menu routine with the counter probe in TP1. Yes, C22 must be adjusted just before running CAL PLL or CAL BFO. I use WWV which transmits 500 or 600 Hz tones on alternate minutes.? Using SSB, align those tones with the 500 and 600 Hz markers on your audio spectrum analyzer to assure that you are tuned correctly. Once you get the KSB2 option installed, you can enter the BFO frequencies suggested in the manual and then proceed to do a more precise dial and BFO calibration. The DAC steps for the BFO limits the precision that you can achieve, but 10 to 20 Hz is achievable. 73, Don W3FPR On 6/28/2021 2:16 PM, jerry wrote: > Hi Don, > > ??

I rolled my own, but it's quite primitive. It runs on my Linux server and I access it via a web browser. It gives me a pair of clocks at the top - local and UTC. At the bottom, there's a big text window for copying code. In between - the list of contacts, plus a form for entering a new one. The current UTC timestamp is automatically put in. The latest contact has a button for ending it - and putting in the "end" UTC timestamp. It was easy to do that, because I already wrote substantial software in support of my business, and the infrastructure was all there - webserver, SSL, libraries for linking multiple pages, templates etc etc. I'm sure that other people have written logging software with features I can barely imagine. Right now, I'm thinking of having it automatically nominate text in the CW copy window for new contacts...."anything that looks like a callsign". Also need something to slice & dice the logbook data for contest reports. - Jerry KF6VB On 2021-06-28 14:16, Michael Walker wrote: > I agree with Jim on this one. :) > > Mike va3mw > > > On Mon, Jun 28, 2021 at 4:55 AM Jim Brown > wrote: > >> Yes, he SHOULD throw it away and learn modern logging software.

The one that works the best for YOUR needs. Generic may not do contests well; contesting logbooks may not do every day well. Some play well with other code; some play well with hardware; some don't do either. Some cost money; some are free.? Some are just crap-ware... It's a struggle; just fill your needs. 73, Rick NK7I (specifically NOT saying which one I use) On 6/28/2021 2:54 PM, jerry wrote: > So what's the hot ticket nowadays on logging software? > > ?I rolled my own, but it's > quite primitive.?

Good luck with extending your own user interface.? I am sure there are contest logs listed somewhere on the web.? Not only would you get a list of CW ops who contest, you could also grab their details to fill in more fields.? Then scan that list with the partial call you copied.? Even brute force search algorithms would be fine. ?? As far as slicing and dicing data Perl, awk, and sed can do wonders with extracting, and formatting individual fields.? Plus they are already available on your OS.? A two line script with any of them can do what you want. ?? The killer app for contesters seems to be N1MM.? I think you will have more fun writing your own since you know exactly what you need and what you like.? Building your own app should not be shamed. ??? GL & 73, ????? Kevin.?

When I upgraded to a KPA1500, again I wanted to have back up using my only other HF rig, the KX3. At full output the KX3 will drive the KPA1500 to 900 Watts.

My Windows 10 laptop takes a full 18 minutes to boot up from a cold start. I've researched this "feature" and had it in to 2 repair places and have been told that the only fix is a SSD for $$$. My old XP machine and even older DOS based machines are up and running in less than 30 seconds. Indeed they are ancient, and vulnerable to modern threats, but with proper attention I have been able to avoid any issues. Certainly, a modern machine is required for some things, but my take is that as we move forward with computer hardware/OSes, we are actually taking a few steps back.

That suggests something seriously wrong with the computer, possibly the hard drive. Or perhaps it is seriously under-powered. I own six laptops, three with Win10-64, two with Win 7-64, and one with XP. None of them take more than a minute to boot. Perhaps there are problems with the hard drive, or there's not enough memory. The XP box is about 16 years old, one of Win 10 boxes is 12 years old, the Win 10 in my shack is 5 years old, and the Win 10 box in the the house is 3 years old. Some of these computers are left over from when I was running my own small biz. Also, my computers last as long as they do because I don't try to buy the cheapest, least powerful stuff, but something with a modern processor, decent hard drive, and plenty of RAM. All of them are Lenovo Thinkpads, some bought new, but most bought used. 8 GB of RAM is an absolute minimum for Win 10, and 16GB is much better. Very nice well-equipped used (off lease) Thinkpads can be bought in the $350 - $400 range. When I've had problems like yours, I've gone to one of the guys in our ham club who specializes in setting computers and solving problems for people who pay him for his services. I can afford to pay him, and I do. I suspect he would do it as a favor, but he needs the money more than I do. 73, Jim K9YC From edauer at aya.yale.edu Mon Jun 28 22:32:46 2021 From: edauer at aya.yale.edu (edauer at aya.yale.edu) Date: Mon, 28 Jun 2021 20:32:46 -0600 Subject: [Elecraft] HOA antenna restrictions Message-ID: <000501d76c8f$0c371aa0$24a54fe0$@aya.yale.edu> I confess to having done something similar, though I used a jiu-jitsu move rather than rational argument as Phil did.

Or one antenna? Only using one band? No; we tend to be packrats (including my entire TS520 station stored away from the 70?s). Having only one is ?a single point of failure? issue. Redundancy is good and repurposing helps. I have several radios and computers. Each radio serves a purpose, some are back ups. Others, like a couple computers, are placed around to simply save walking to access one lol, in handy places. Each computer serves a purpose also; as needed. Such as IRLP node, weather data collection and collation, producing a web page to present it; critter cam management with shared presentation and scanner streaming (since no one else around here does that). Each element carries a load, more gets done. I have back up computers stored also in the event of failure (or someone in need, I?ve given several away). I like toys and I share well with others. Windows is not the only OS, there are options available. Some still work really well on ?old? hardware. And yes I have a fast multi core running at GHz speeds, with multiple fast hi-Rez displays for critical things like station ops hi hi. As well as a Pi, just to play with. I said I like toys.

One solution for software that needs an older OS is Virtual Box. I'm using on a Win10-64 machine to run an ancient version of Quicken that I don't have to buy every year. It's running in an XP box. You can load a lot of different OSs if you have them on media to get them loaded. The > next try will be on a 3-1/2 inch floppy (have one of those floating > around??) Yep -- both in two dead towers from around 2000, in a couple of ancient laptops that still work, and one I recently bought that goes to a USB port.

Rent a station is NOT ham radio.? Argue all you want; but ham radio is about RADIO, even if it's just owning and using an HT because that's all you can manage. You may as well log cell or Skype phone calls or EchoLink contacts (or IRLP, DMR, DStar etc) as use remote stations that are not yours; they have equal merit; none, zilch, nada, nil.? Only a few even have a radio involved; the rest is internet links; not ham radio. EVERY entry in my log is from MY gear, a station assembled by ME (sometime with help building etc), a result of MY best efforts at THAT point in time.? It's a matter of pride and is a moral imperative to my standards.? Yes, it means I don't make EVERY contact or work every DX when I want; I have to wait for propagation, then hope I've done enough.? Yes, I've put money into equipment to own, use and maintain; not someone else's pocket to rent.? But I EARNED every log entry. I pity you some; you've lost your compass.? Yes, you can get DXCC in an afternoon, moving sites to best apply propagation <>.? It's NOT your station, it's not worthy of your log; it has no value, because you purchased your log and awards instead of investing your time and efforts. It's your ego being stroked by your wallet. Ditto using remote receivers to augment your own; your station can or cannot; it's THAT simple. You have ZERO emergency preparedness without a radio; one of the tenets of ham radio.? You can't be prepared if you don't own a radio; if the systems are down, you have nothing.? An HT can at least saturate the neighborhood to check on others around you. If you are so HOA bound that nothing outside can grow as an antenna (has NEVER been totally exclusive; stealthy has a market); build a club station where you can; drive there to operate it and log from that.? If it is an emergency and there IS still access, then use the remote if you have nothing else.? At least own and learn to use a portable radio (KX3, dual band HT, SOMETHING). Yes, I operate a station remotely; MINE.? And if done well, no one knows where you really are at the time of the contact. But you won't ever sell me that not owning a radio at all and to rent and operate remotely is even CLOSE to being a ham.? For pity's sake, hand the man an HT! Harsh, perhaps.? But it's also one reason to escape the blasted HOA world too to make your own decisions. HOA is an infestation, a virus that allows others to make choices for you, even if you don't like their decisions. /rant off; hot button; this arena gets old fast/ 73, Rick NK7I More curmudgeonly every year it seems, ain't nuttin wrong with old school, it's just not as popular On 6/28/2021 8:41 PM, William Levy wrote: > Gents, > > Let me remind all of you in an HOA that you don't need to put up antennas. > You can join remote ham radio dot com and use giant antennas all from your > website.

Also, my computers last as long as they do because I don't try to buy the cheapest, least powerful stuff, but something with a modern processor, decent hard drive, and plenty of RAM. All of them are Lenovo Thinkpads, some bought new, but most bought used. 8 GB of RAM is an absolute minimum for Win 10, and 16GB is much better. Very nice well-equipped used (off lease) Thinkpads can be bought in the $350 - $400 range. When I've had problems like yours, I've gone to one of the guys in our ham club who specializes in setting computers and solving problems for people who pay him for his services. I can afford to pay him, and I do. I suspect he would do it as a favor, but he needs the money more than I do. 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 wa6vab at gmail.com From wes_n7ws at triconet.org Tue Jun 29 01:15:42 2021 From: wes_n7ws at triconet.org (Wes) Date: Mon, 28 Jun 2021 22:15:42 -0700 Subject: [Elecraft] HOA Crap In-Reply-To: <51d73949-58de-b605-d0df-62ef3f62e89b@gmail.com> References: <51d73949-58de-b605-d0df-62ef3f62e89b@gmail.com> Message-ID: I was going to write something like this and then I looked at his QRZ page and changed my mind.

I?d recommend at least 32 radials - as long as you have space for. On or in ground is fine. Yes, and I'll suggest that you buy the tallest one that the HOA will approve, simply because taller makes it more efficient. Also, on-ground or buried radials don't have to be resonant or all the same length. The only rule of thumb is that more wire on the ground is better. Wire size is important only to the extent that it's big enough to hold up better. Wire can be insulated or not, but definitely NOT stranded (less corrosion). 73, Jim K9YC From foxfive.vjc at gmail.com Tue Jun 29 01:29:41 2021 From: foxfive.vjc at gmail.com (F5vjc) Date: Tue, 29 Jun 2021 07:29:41 +0200 Subject: [Elecraft] HOA Crap In-Reply-To: References: <51d73949-58de-b605-d0df-62ef3f62e89b@gmail.com> Message-ID: Yes, do take a look at his QRZ page! :) On Tue, 29 Jun 2021 at 07:17, Wes wrote: > I was going to write something like this and then I looked at his QRZ page > and > changed my mind. > > Wes N7WS > > > On 6/28/2021 9:45 PM, Rick Bates, NK7I wrote: > > No! > > > > Rent a station is NOT ham radio.

Think again, they are far from secure, unless you spend several hours disabling a lot of "phone home" & auto update facilities in all the pre-installed (and usually unwanted) crap-ware (sometimes including parts of the OS itself) that are often nigh on impossible to un-install. If you want "security" never connect it to any network, certainly never the internet! If you do use the internet, then at the very least disable UPnP in your gateway/router device.?? And keep said gateway/router device firmware up-to-date (and ensure that UPnP is OFF after such updates!) And as for efficency...?? Have you measured the power consumed by a modern PC when watching streamed video for example? Much of the older technology was built for reliability too, not the cheap mass produced lead free tin whisker prone stuff of modern times.?? Dont either fall into the trap that SSD's last forever.? They wear out too, but in different ways. Best to use a SSD to boot from (largely read only) but keep the swap file and user working data on a rotating-rust drive. Archives can go on the SSD (as well as an off site store...) I wonder if the Linux based OS in the K4 is locked down, firewall on and configured to drop incoming requests by default, with certificate only based remote access for example where needed, and full (different certificate) authentication when/if it phones home to Elecraft, to help mitigate MITM spoofing issues.?? (Man In The Middle.) If you can "see" it (or any other PC/device) on your network, it(they) is(are) not secure. You wouldn't want your shack to be compromised by malware in the radio, or lightbulb!? (Yes, there is malware/ransomware for Linux, not common yet, but nasty.) 73. Dave G8KBV.

But for those of us who keep them I understand. Why throw away something that is still functional? One of my "many" hobbies includes vintage computers. Considering that I use my IBM 5150 to write 1702 EPROMS justifies not throwing the old machine away. I use another older DOS machine to build images for my PDP11 that uses a SCSI controller. New hardware can't do this. The newer machines don't support older style parallel and serial ports. The buss on the motherboards do not allow for ISA cards. Also many hardware devices expect a 4.77 Mhz clock. DOS box and other emulators don't interact well with real hardware. And last... I love the new mentality that anything more than a few years old should become eWaste. All this "obsolete" just is overwhelming our landfills. People toss out cell phones, computers, TV's way before their useful life is up. You do what you want, my parents taught me not to be wasteful. 73 Len -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Dick Sent: Monday, June 28, 2021 7:09 PM To: Elecraft at mailman.qth.net Subject: [Elecraft] Old DOS computers I will never understand how those in the Amateur radio hobby can spend thousands of dollars on equipment, yet they keep old PC?s that are not very efficient at all, nor are they secure.

Considering that I use my IBM 5150 to write 1702 EPROMS justifies not throwing the old machine away. I use another older DOS machine to build images for my PDP11 that uses a SCSI controller. New hardware can't do this. The newer machines don't support older style parallel and serial ports. The buss on the motherboards do not allow for ISA cards.

The ThumbDV cost me $99 a few years ago. I had the Raspberry Pi I run the server for it on lying around going unused. The most I pay for it is a dynamic DNS link I use to reach the server via my phone when I'm not at home. The server lets me access it from any computer in the house, or from my Android phone.

In-Reply-To: References: Message-ID: To follow up. Had a 20m cw station 3 elements 56 ft up. I spent some time with the GOTA station using my KX3 on 20m phone with 3 elements 30 ft up. Preamp off, att off. 210 ft separation. Could faintly hear the CW as broad background noise, but only detectable, not strong or bothersome. No thumping. Could have been a function of how clean/dirty the CW transmitter is than anything else. So, in this situation, completely fine coexistence. Yes, I'd still prefer a richer set of performance numbers from bench measurement of both radios, but then it's like work instead of hobby. :-) Anyway, the GOTA operator who had never made a QSO before was tossed into the deep end of the pool of trying to work SSB phone during the madhouse that we call Field Day. :-) When he was done, he said he wasn't a fan of the extreme challenge of FD contesting. I told him he should try any other day of the year. And I'm sure he will. Could be he's really a CW op. Maybe he'll find out. Sitting with him and coaching him through the patience and the 20 million subtleties, I was impressed watching him bust through the pileups some of the loud stations on 20 had going. Got one by pausing before dropping call and another by picking up on an out of rhythm cue. When he was picked out of the horde, the QSOs themselves were easy.

Our ARES group fell for the ICOM D-STAR story about 10 years ago, even got the county to spring for several repeaters. One is on the air unused for the most part except by one or two diehards and the other sits in the warehouse in the original boxes. That's why I was hesitant when the local SAR group (not affiliated with ARES) went with DMR lately and several of our ARES leadership tried DMR. Long story short - I've been active on DMR for the last month or so, split time between nets and QSOs on various TalkGroups using both the one repeater that I can reach using a 5-w hand-held inside my apartment and the SkyBridge HotSpot where I can talk to the world. My first QSO was with a ham in the UK! There are plenty of DMR repeaters on the West Coast that are all linked up. I wish that I could do that with my K2 and I miss doing so. But I'm still keeping it and occasionally see who I can contact with a dummy load... :-) (There's one guy in the neighborhood who claims that he can read me when I use 100 W into MFJ's "finest".) 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From w2xj at w2xj.net Tue Jun 29 12:48:05 2021 From: w2xj at w2xj.net (w2xj) Date: Tue, 29 Jun 2021 12:48:05 -0400 (EDT) Subject: [Elecraft] HOA Crap In-Reply-To: References: <484692fc-ccbf-ce37-f65b-c5ade19a0b74@benlomand.net> <56393cda-b8a9-ad55-d2d8-c9ace2177f50@benlomand.net> Message-ID: <1304043315.21021.1624985285518@webmail4.networksolutionsemail.com> Can you provide a link to it? > On June 29, 2021 12:27 PM Jim Brown wrote: > > > On 6/29/2021 7:50 AM, Bob McGraw wrote: > > I totally agree. > > Did you do as N7WS suggested and look at this guy's website> I did. > > 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 w2xj at w2xj.net From rich at wc3t.us Tue Jun 29 13:15:08 2021 From: rich at wc3t.us (rich at wc3t.us) Date: Tue, 29 Jun 2021 13:15:08 -0400 Subject: [Elecraft] HOA Crap In-Reply-To: <1304043315.21021.1624985285518@webmail4.networksolutionsemail.com> References: <484692fc-ccbf-ce37-f65b-c5ade19a0b74@benlomand.net> <56393cda-b8a9-ad55-d2d8-c9ace2177f50@benlomand.net> <1304043315.21021.1624985285518@webmail4.networksolutionsemail.com> Message-ID: <0aed01d76d0a$522f6fa0$f68e4ee0$@wc3t.us> https://www.qrz.com/lookup/n2wl -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of w2xj Sent: Tuesday, June 29, 2021 12:48 To: jim at audiosystemsgroup.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] HOA Crap Can you provide a link to it? > On June 29, 2021 12:27 PM Jim Brown wrote: > > > On 6/29/2021 7:50 AM, Bob McGraw wrote: > > I totally agree. > > Did you do as N7WS suggested and look at this guy's website> I did. > > 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 > w2xj at w2xj.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to rich at wc3t.us From jim at audiosystemsgroup.com Tue Jun 29 14:15:02 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 29 Jun 2021 11:15:02 -0700 Subject: [Elecraft] HOA Crap In-Reply-To: <1304043315.21021.1624985285518@webmail4.networksolutionsemail.com> References: <484692fc-ccbf-ce37-f65b-c5ade19a0b74@benlomand.net> <56393cda-b8a9-ad55-d2d8-c9ace2177f50@benlomand.net> <1304043315.21021.1624985285518@webmail4.networksolutionsemail.com> Message-ID: <55fc6c9b-f98a-6738-6949-72eb032a0e7b@audiosystemsgroup.com> On 6/29/2021 9:48 AM, w2xj wrote: > Can you provide a link to it?

Yes. Two things. With all this guy has done with ham radio, I don't think anyone has the right to lecture him on what ham radio is. And eventually, if we live long enough, all of us are likely to be in situations where having our own station is simply not possible. I fail to see a problem with operating another station remotely. My only objection (and is a STRONG one) is the use of a station geographically positioned to add a new country or band country to one's DXCC count. 73, Jim K9YC From wes_n7ws at triconet.org Tue Jun 29 15:41:25 2021 From: wes_n7ws at triconet.org (Wes) Date: Tue, 29 Jun 2021 12:41:25 -0700 Subject: [Elecraft] HOA Crap In-Reply-To: References: <484692fc-ccbf-ce37-f65b-c5ade19a0b74@benlomand.net> <56393cda-b8a9-ad55-d2d8-c9ace2177f50@benlomand.net> Message-ID: <7c66f9c8-1776-6b42-3664-258d265636ef@triconet.org> Apparently so.

[With apologies to N4ZR. I'll try to tie my comment to germain topics.] I generally disagree with NK7I's comments because I think ham radio is a huge tent, and the point is having fun. However, this comment tickled the thought that setting up remote receivers could be something hams do regularly. I can imagine a remote receiver at one son's house in Colorado, and another at the other son's house in California. These receivers might be useful for activities like the Elecraft net, where frequently the QRO stations, which are the backbone of the net, can't hear the QRP stations who try to check in. It would be a fun project in station building. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz | Re: Computer reliability, performance, and security: 408-348-7900 | The guy who *is* wearing a parachute is *not* the www.pwpconsult.com | first to reach the ground. - Terence Kelly From rick.nk7i at gmail.com Tue Jun 29 17:03:42 2021 From: rick.nk7i at gmail.com (Rick NK7I) Date: Tue, 29 Jun 2021 14:03:42 -0700 Subject: [Elecraft] HOA Crap In-Reply-To: <9dfeb410-8772-7558-9f24-17d4ded7e3b9@gmail.com> References: <484692fc-ccbf-ce37-f65b-c5ade19a0b74@benlomand.net> <56393cda-b8a9-ad55-d2d8-c9ace2177f50@benlomand.net> <9dfeb410-8772-7558-9f24-17d4ded7e3b9@gmail.com> Message-ID: <4a1652a4-ea45-d2d6-1a6c-cf236accfeca@gmail.com> The difference there is that you(r club) own/s, maintain/s the station, not rents it.?

Jim, I agree, rental hopping for the purposes of DXCC or similar, is equally immoral and as such, should be banned from such awards.? Use your own, a club or a friends station WHILE physically there if your morality reaches that far.? Mine doesn't; I've used other stations and entered into THEIR log, not mine (the station is not mine, simple). I've read the OP page on QRZ and that's all great; a life WELL lived.? But to call a non-radio owner a ham, just isn't right. It's ham RADIO, not ham internet. Noise was one of the reasons for me escaping the HOA world; some things just can't be fixed.? I was able to make informed choices on my purchase, which has made ALL the difference (in DXing at least).? -127 dBm is my normal noise floor on most bands now; not the -80 I had before. At the least, own a simple HT, KX#, to call yourself a ham in more than license. 73 all, Rick NK7I On 6/29/2021 12:47 PM, Gordon LaPoint wrote: > I setup a remote about 10 miles from my house, with KT1I and WB8PKK, > because KT1I had to move into an apartment with no antennas, and my > noise level has gone to 20overS9 on 80-20 and is some what bad on > 18-10.?

You can have fun renting a sports car or renting a nice ham station in a good QTH, but neither is the same 'achievement' as owning your own. For me, it doesn't feel as rewarding to use internet linking or remote rigs; what makes ham radio cooler than the Internet is how little infrastructure we need. Talking directly to someone hundreds or thousands of miles away using a couple pieces of electronics and some wires is *magic* to me. But I don't think renting is 'worthless'; for some folks, that magic comes from talking to people halfway around the world, and a little extra infrastructure in between doesn't ruin it. Plus, you're still honing some of the same skills you'd use for local operation. I do think renting passes up a chance for even casual emergency preparedness; having and knowing how to deploy and use your own station is potentially useful in emergencies. I can, however, imagine that remote stations outside a disaster area could be helpful in routing traffic to and from the disaster area. Like a lot of aspects of this hobby, it boils down to: do what you find personally fun and rewarding, share it to inspire others, and don't tear down what other folks enjoy. 73, Julie On Tue, Jun 29, 2021, 17:07 John Jolly wrote: > Been reading the 'rent vs own either does or does not = reality' posts and > am in a bit of a quandry. > > So when I rent a car to go on vacation, then it's not a vacation? > > 73, > > John, N7NWL > ______________________________________________________________ > 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 julia at juliatuttle.net > From lists at subich.com Tue Jun 29 18:00:47 2021 From: lists at subich.com (Joe Subich, W4TV) Date: Tue, 29 Jun 2021 18:00:47 -0400 Subject: [Elecraft] HOA Crap In-Reply-To: <4f44cbd2-83b5-b18c-a23c-1eec4fdf681b@k0dxv.com> References: <4f44cbd2-83b5-b18c-a23c-1eec4fdf681b@k0dxv.com> Message-ID: <97ba9a86-340e-0cf4-ca1b-9d1a34a1b710@subich.com> On 2021-06-29 5:40 PM, Doug Person wrote: > I own a condo in Loveland, CO just south of Fort Collins.

Using a remote station that you own/use exclusively is one thing. Using a remote station that rents by the hour - in New England one hour, the Pacific Northwest a few hours later, perhaps in Hawaii or Puerto Rico the next day ... that simply is no longer Amateur Radio. "Rent a Shack" is about as close to commercial radio as one can come and still pretend to be amateur. I'm not talking about a rental condo/home in some Caribbean island for a week or two holiday with a ham shack for "down time" (or a contest weekend) ... that is more like using a club station, a friend's shack or tossing a wire off a hotel balcony on a business trip. However, "shopping" rental stations for the best propagation to work some DX station is simply immoral. ARRL should modify DXCC (and contest) rules to limit the use of "remotely controlled stations" to *one station*, with all transmitters, receivers and antennas within a 500 foot circle of which the licensee is the sole owner of the station. 73, ...

No, they understand that may move a lot. *HOWEVER* even the most mobile don't move around the country at the speed of light. They don't make one contact from Maine followed by a contact from Washington State, followed by a contact from Coastal Carolina, follow by a contact from Southern California depending on the best path to the DX.

We do if we take the challenge of DXCC seriously. I started over when I moved from Chicago to Santa Cruz 15 years ago. I would have viewed it as cheating if I hadn't. I didn't start over when I moved the much shorter distance from SW WV to Chicago.

Some people object to anything that isn't what they thought ham radio was 50 years ago. And what W4TV said -- that's MY objection. The DXCC rule that a ham can operate from multiple locations anywhere in the lower 48 (for example, San Diego, Seattle, Maine, and Florida) and combine all of the QSOs for DXCC is ludicrous! Especially since the ham but can't combine them if he were to move from Detroit across the river to Windsor, ON. 73, Jim K9YC From rocketnj at gmail.com Tue Jun 29 20:25:18 2021 From: rocketnj at gmail.com (Dave) Date: Tue, 29 Jun 2021 20:25:18 -0400 Subject: [Elecraft] What is DX?

Ham radio is what you make it. Your version is just fine for you. How you actually get on the air is not a law. It isn't a requirement. All you have to do is work within the legal requirements for your country. What would you do when you have to move into assisted living? Where the house is not your own. Will that take you off the air? Make contacts any way you can. For you, get on the air and make contacts. BTW, you can't force your vision on anyone. You can preach it, but that doesn't mean anyone has to listen to it. :) Everyone is wired just a bit differently (some like me, a lot different). 73, Mike va3mw On Tue, Jun 29, 2021 at 12:47 AM Rick Bates, NK7I wrote: > No! > > Rent a station is NOT ham radio.

Any DX you work from within the USA can count towards your DXCC credit.?? Worked All States has a 50 mile radius of your home station, that being said you can have more than one WAS account if you want to achieve WAS from other areas.?? I have a friend who splits living in FL and NY.? He has an account for each location for his WAS. As for contests you need to use the exchange information for the transmitter location (remote station), State or Section for domestic contests, ITU or CQ zone for those contests.? Serial no. contests really do not matter much I guess. > > If you're doing it for the fun of it, I feel like borrowing someone else's > is fine. > > I'll throw in a related question: what's the right way to identify or > disclose when you're borrowing someone else's station? I've got 15 W into a > random wire in a noisy city QTH, but my girlfriend one state over (but same > FCC callsign digit) has 100 W into a proper 40m dipole in a quiet rural QTH. It does not matter whose station you are using your call is your call,? keep in mind if your friend (or anyone) gives you permission then you can use their call.?? You can even borrow a call to use during a contest.? Example in the CQ WPX contest it is all about being a rare prefix.?? So if you call is K6xxx, K6 is very common, but you have a friend whose call is AC6xxx, much more rare,? you can with permission use that call during the contest. That being said you can only operate within the limits of your license unless they are present and acting as a control operator and monitoring your operating.

I'm a VEC and over the last year have participated in several tests which resulted in over 100 new hams (not bad for a county of only 18,000).? Most were over 50, some 30-40's and a handful are juveniles (under 18).? At the last test, a woman in her 80's tested (failed, but it didn't break her spirit, she'll try again; GREAT attitude).? This is an older county, most of the younger crowd leaves to find a career, attend college or be in the military (no career prospects here, but farming, logging, milling and working at a local store).? So the ham representation here tends to be 40-ish and higher for new hams.? The younger crowd is more interested in starting their lives and making a living; very challenging here. Since the class only has time to teach to the test (no real learning involved, just answers) the local club meetings have short sessions about "I'm licensed, now what do I do?'? Without such information, these neophytes will never progress and the hobby, along with their interest, dies.? It's good old fashioned Elmer'ing and we help each other build stations. Most noobs tend to get the cheaper $35 imported radios, until they learn just how filthy those are on the air (learning creates change which allows progress).? They are taught how to use it, program it, what to (not) discuss on the air, manners, protocols and in general HOW to be a ham.? They are exposed to many facets of ham radio from contesting and DX (which tends to be connected); satellite, HF, EME, repeater operations, including the local RF linked network (and more) AND how to apply theory (this month discusses "What is antenna gain and when/where do I want it?"). In ALL discussions, a radio is involved; even for those able to start building an HF station (just like when I started 40 something years ago) or put up a 2m ground plane.? They are taught to NOT turn all knobs to 11; to read the manuals, adjust carefully (and why) and generally how to properly produce the cleanest signals they can (some radios make that a challenge).? Progress is slow, which is fine as long as it's forward. Surfing the internet to use a receiver (other than scanning fire calls) is never discussed; it has little to do with running a ham station.? The only discussion about the internet is when logging, spotting and filing entries is covered.? (I'm not SO old school that SOME new tools are taboo.) Ham radio is better without gaming the system to seek an advantage and remote stations for rent, do exactly that.? It creates an unfair advantage and only requires a fat wallet, not the knowledge and experience gained by making your own station and learning how to maximize it's ability.? Put another way, rental buys the plaques, awards and acclaim with a wallet, not with ability.? Such items are valueless because they weren't earned by effort, but money. I've driven VERY fast sports cars (and proven that they are both quick and fast, while being scary responsive), but it doesn't make me a race driver.? Renting a world class station, even if I bring my own radio; doesn't make me a world class contester/DXer, just someone with 'disposable income'.? To me, the only real fun would be to have different propagation than what I have at home. If I build the race car (or radio station) by hand, know intimately EVERY part and it's place, then learn how to best use it; then I can call myself improved and eventually qualified to operate it.? Winning the race (contest) or not simply allows me to rate my progress over time (my competition is me against me, EVERY time, just like golf).? In a small group, we 'motivate' each other to improve the stations and number of DX worked and condole with each other when there is a failure or poor showing. You're right, remote operation of another persons efforts is legal but that isn't the point.? Being able to do something doesn't make it morally right.? With remote rental, you're taking credit for another persons efforts.? You didn't EARN that plaque/award/score if you didn't help put it all together; you bought it. I'm not forcing anything on anyone, everybody has a moral code and choices to be made.? I've made it clear that mine is that I'll only count (log) from a station that I built/assembled and not any other station.? I may use other stations, but they won't be in MY log book. IF that day comes that I can't manage the station anymore; I'll move to an HT and keep in touch with my neighbors and make new friends.? If I degrade below being able to manage even that, I probably wouldn't know the difference anymore (it won't matter). It is ham radio, not Xbox; it uses RADIO, not a game panel.? The internet is a tool; it's not ham radio without a radio. See you on HF! 73, Rick NK7I On 6/29/2021 5:51 PM, Michael Walker wrote: > Rick > > I think you need to look at the average age of today's ham (hopefully, > it is going down). > > Ham radio is what you make it.?

The "handlebar" on the S Max is not a straight bar, but a round donut type of handle. All of the Cell phone handlebar mounts will not work with the KX2. Any one with any ideas out there? Thanks, Mike Take a look at Lido Mounts (www.lidomounts.com ) that offers a bicycle mounting bracket that one can then attach various mounting points for different items such as HTs and front panels of various radios. See if the panel they offer will for the KX3 will work with the KX2. I have a Segway I2 which has their mounting piece for a bicycle that I?ve attached their mount to hold a HT using the belt clip. So the question is whether you can ?mix and match? to get what you need. There is a mounting package for the KX3, but it includes hardware for mounting the assembly in a vehicle, not a bicycle. You can call them at 949-690-5616 to discuss your needs. They?re on the West Coast so take that into account when calling them if you?re not on the West Coast yourself.

Looks like quite a little project. The workbench is cleared off, soldering iron loaded with its smallest tip, Panavise in place & grounded, anti-static strap hooked up. ....Lemme at it! - Jerry KF6VB ------------- endsnip ------------------- Am about halfway through stuffing the circuit board. Installed most of the caps, ICs, resistors. A few parts, I put off installing because they are at the very edge of the card, and would prevent me from holding it in the Panavise. Each part that I did not install, I put a big circle around in the manual. When everything else is stuffed, I'll go back and install those. One of the resistors went *SPOING* and flew across the garage. Luckily, I have complete stock of all the common values of jelly-bean 1/4W resistors. I shouldn't have to do much to the base K2, because it already had the SSB installed - somebody had removed it and reinstalled the bridging cap. I will however need to pull the control board and pull a couple of jumpers off the microphone jumpers array - that will be my excuse to treat the control board to a good scrub with alcohol. - Jerry KF6VB From phystad at mac.com Wed Jun 30 12:08:41 2021 From: phystad at mac.com (Phil Hystad) Date: Wed, 30 Jun 2021 09:08:41 -0700 Subject: [Elecraft] Temperature or Warmth of KPA500 when "Off" ?

An alternative would be to run QEMU on the Pi, which provides an x86 execution environment, and then try to get the N3FJP software running under Linux Wine (Wine provides versions of the Windows libraries needed by a? Windows app that translate to linux libraries / system calls). I'm not saying this is an easy path to follow, but there are a lot of people who have succeeded doing this. The N3FJP software is simple enough that it would probably work reasonably well. Getting all the pieces in place though will be difficult, unless you can find an appropriate canned image for the RPi that already has Wine and QEMU installed properly.? Here's a two year old one for a RPi 3 running Debian Stretch: https://sourceforge.net/projects/pi-qemu-wine/ People have been successful getting WIne running on Qemu on the RPi4 and newer Linux distributions, but I haven't seen a canned image for use by those who are not linux / QEMU experienced users. Here's a link to a tutorial that was used to create the above canned image (including a youtube video).? People have adapted that to make things work on the RPi4, etc : https://www.novaspirit.com/2019/04/15/run-x86-arm/ There used to be a (non free) x86 environment for the Raspberry Pi called Exagear Desktop, but that is no longer available (but there are plenty of articles on the web giving instructions on how to run Wine on Exagear Desktop, so don't go down that rathole). Anyway, there's a lot more web pages that discuss this, and perhaps there is one out there that is more recent that would allow you to get it all running on a RPi 4. 73, John, AC0ZG On 6/30/2021 10:38 AM, Mike Short wrote: > Atomic Pi is an alternative for this.

Although I don't live in the Mac world, I'm told that there are decent logging programs for Ios. Dunno about iPad. Skookum Logger is one I've seen mentioned. About five years ago, I bought a used X230 Thinkpad (the smallest and lightest weight in the family) for much younger guys to drag up a 3 mile trail that gained 1,000 ft elevation to activate very rare grid CM79. I also bought a high capacity battery for it as a spare. On several trips, they got most of a day out of it before needing to change the battery. It's a very capable computer, and we've used it in several portable setups for contest logging, including FD last weekend (running N1MM+), but not on its own battery. On FD, we were 1A Battery at 5W, so we ran it from a DC-DC supply running from solar-charged 12V lead acid batteries. DC-DC converters are usually RF-noisy, but W6GJB found one that isn't. 73, Jim K9YC From wabernat at gmail.com Wed Jun 30 15:05:19 2021 From: wabernat at gmail.com (William Abernathy) Date: Wed, 30 Jun 2021 15:05:19 -0400 Subject: [Elecraft] SDR filter improvement Message-ID: Hi, Seems that SDR radios have software emulation of mechanical filters like noise reduction.

You can download that manual to check - I know that one works.

It is normal. The microcontroller is on, but sleeping when the rear-panel power switch is on. It needs to run to be able to respond to serial commands and for the front-panel power-on button to work. It is powered by the 5V linear regulator, which is providing the heat you feel, along with the +12V and -12V regulators (also linear). I seem to recall that the input to the regulator is something like +15 or +18V, which gets regulated down to the three supplies that are used for running the microcontroller the RS-232 interfaces and the LCD. The LCD is disabled when front-power is off. So yes, the small amount of heat you feel is quite normal. 73, Jack, W6FB > On Jun 30, 2021, at 3:16 PM, Dave wrote: > > I would assume so, as mine is the same way...

I swapped out USB cables to no effect. I swapped out another Win 10 computer to no effect. On Win 10 I went into device manager and confirmed the FTDI serial emulator on COM4 was working properly. I went into the config tab on N1MM+ and confirmed the K3s was linked to COM4 and the proper settings were still in place, 38400, N, *, 1, no, no. I swapped USB sockets on the computer to no effect. I changed to COM9 on both computer and N1MM+ to no effect. I rebooted the computer and the radio after every change to no effect. The K3s does respond properly to the Winkeyer on COM5 and it transmits and receives using VOX normally. I don?t know where to go from here. Assistance greatly appreciated.

The ambient temperature is really not the issue as much as whether heat is carried off. I know it's hot in the pacific northwest but I think you can still enjoy your gear. The larger issue is RFI from air conditioners. The environmental consideration many people neglect is atmospheric pressure. As altitude increases, there is less air to carry the heat away. People sometimes install fans with an idea to sucking out the heat. This is actually wrong. The fan should blow ambient air in and the venting for it to get out should intend that pressure inside the case be a bit higher than the ambient pressure. More molecules against the hot part, the better. If you read the fine print on electronic specifications you will often (and should always) see an atmospheric spec with the heat spec. All the above is just rule-of-thumb of course. There is a lot more to cooling electronics than the above but I think these are worth considering. Elecraft gear is pretty good at protecting itself as well. If your radio cuts out, it's doing its job of living for more fun later.

So I pulled the card out, scrubbed it again with IPA, stuck it under the microscope to look - again - for solder splashes and cold joints. Scraped off a little something here & there. Also, I had doubts about the connections to the input & output transformers. So I hit those again with the soldering iron. Put the card back in the K2 - and ...Wow! Lively SSB receive! RF out on transmit! Still need to align the rig. Piping the output into another ham rig through a big attenuator - it sounds pretty good. One niggle - carrier suppression. If it's nulled out for LSB, it's not for USB. The nulls are in different places on the pot. I guess you set a compromise position, and make sure the carrier is off the skirts of the filter, so that can help. - Jerry KF6VB From n6tv at arrl.net Wed Jun 30 22:07:16 2021 From: n6tv at arrl.net (Bob Wilson, N6TV) Date: Wed, 30 Jun 2021 19:07:16 -0700 Subject: [Elecraft] Case-maker Rose's OM K0PP, SK Message-ID: Retired case-maker Rose, N7HKW, and her OM Ken, K0PP, seemed like part of the Elecraft family for so many years. https://buttefuneralhome.com/obituaries/kenneth-glenn-kopp-age-83-of-anaconda-montana/?fbclid=IwAR2OvmrovnqFtcmHs2oMmg-lS8c3_YN27SilgKHGdpDz82MQpr5Lzq9d-VE Condolences to Rose and her family.
