[Elecraft] K3 Basic 10W DSP1 firmware missing
Ser #893 comes up with ERROR DSE when turned on. I connected via the Utility software and tried to load all new FW but I get an error...no echo d and it goes into lockup. Repeated this several times before I noticed the FW 5.26 is loaded as is the mcu but it is showing question marks for DSP1 and DSP2. Basic 10w k3 so no second receiver. Any advice on how to get the DSP FW to load? If I get the download started it stops after the first reset with the echo error. Not my K3, just trying to help a friend out.

[Elecraft] K3 displayed power out is incorrect
During operation with a home-brew mag-loop antenna, my K3 (#1222) dropped power to just under 50W (by the display). There had been an occasional arc in the external loop tuner, so I'm assuming that was the cause of the K3 failure. Subsequently, running the 50W TX Gain Calibration, some bands pass but other do not. Pass-or-fail, however, power out on the dummy load shows more than 100W but K3's displayed power is on the order of 50W (definitely not right). Note that 5W TX Gain Calibration appears to work fine. During normal keying from a straight key, output power (seen on dummy load) ramps up quickly with KPA in operation and I get 100W out (on dummy load) when K3 display shows 40W. Because I'm getting full power on the dummy load, I'm thinking this must be something simple like a blown resistor in the metering path or gain-control circuitry. I get no error messages during operation and only get the TX Gain Failure message during calibration. I'd like to try a repair myself and would appreciate any counsel or direction.

It is not a job for the faint-hearted. However, if you take your time and cut the mounting pins of the encoders before you unsolder them, then you will succeed. Do not attempt to remove the LED board. Make sure you wick out the mounting holes thoroughly or you will have difficulty installing the new encoders.

Re: [Elecraft] KPA1500 Amplifiers are now shipping from Stock
Sorry, but it is not that simple to know exact status of every product these days. I'm not sticking up for Elecraft, either. I just retired from the military tactical commo world and since late 2019 info from component suppliers began to be, and still is now, nothing less than meaningless drivel. I ordered parts from Mouser for my own needs over a year ago. The last note I received has marked it for delivery in 2024. COVID ravaged the way my old company did customer service. Like it or not, life has changed and never will be what we used to know as "normal". "...regularly informed" nowadays is nothing more than copy and paste of the update 6 months ago.

Re: [Elecraft] Speaking of Counterpoise. The Wireman description
I used The Wireman 26 AWG and it is as they advertise, quite “invisible”. When operating at or above an average power of 25 - 35 watts on 40 mtrs, it gets warm after awhile. I finally elected to go with a similar 18 AWG wire and now I can work modes like PACTOR all day long without too much heat building up. The 18 is hard to see, just like the 26. I also installed a 1.5 KW UNUN when upgrading the wire, and that helped with heat buildup at that component. For reference, this is all when using a barefoot K4D.

[Elecraft] Sherwood Receiver Tests
Reading the Sherwood tests today I noticed the K4D tested ranked below the K and K3s and I started to look at the data published and I am still a little unsure of why it scores lower having assumed it would be significantly better in performance over the K3 and K3s. Perhaps somebody could point out to me if I am not seeing what is important. I believe in if I can hear them, I can work them but like most folk I like a quiet noise floor and a comfy buffer of audio over noise. My current thinking is hold onto my K3 until the K4 is improved as my upgraded #679 has served me so well and is the only transceiver I have ever loved and kept. It's not going anywhere soon hi hi.

[Elecraft] D-104 Mic Element Replacement
If you have a working, unamplified D-104, the solution to this is quite simple. Back in the 1990s, my transceiver was a TS-830S. I had a pre-citizens band D-104. These classic microphones were much heavier than the later ones and had a stamped serial number plate riveted to the head. The output of these microphones was very high and, when connected to an input with an impedance of a few tens of thousands of ohms, the frequency response was very strident. The Astatic data sheet for the D-104 contained a graph, with curves, which showed how a lower impedance load suppressed the mid range and bass response. Inside the base of the push to talk stand, I placed a 787 kilohm,, quarter-watt, metal film resistor in series with the hot side of crystal cartrige output. The D-104 no longer sounded shrill. The response was silky smooth, as determined by transmitting into a dummy load and recording the audio from a second transceiver. As a bonus, I could then run my mic gain at eleven o clock, rather than nine o clock. This made it much easier to set the mic gain properly, as the control was not so touchy. I was actively DXing, back then, and the slightly modified D-104 did a great job of breaking pileups. I was often complimented on my audio and often asked what microphone I was using. Gary, K0CX “Most D-104 mikes are not suited for use with today's radios.? The original D-104 was designed to work into a load impedance of 4 meg-ohms or higher.? Today's radios microphone input is about 50k ohms or so.?? The result is then excessive load on the D-104 element.? This is the major cause of frequency response issues.

[Elecraft] On ground - in ground radials
A friend was installing a homebrew, two tower, vertical directional array in his back yard. His method of placing the copper wire radials below the surface of the ground was quite unusual. He slowly crept along the ground on his hands and knees, while pushing a skil-saw, with carbide blade, against the ground. After sawing a slot, he poked the wire in with a homemade, forked tool. Stomping on the ground closed the opening. I don’t recall how many carbide tipped saw blades it took. His neighbors were probably questioning his sanity. Gary, K0CX With regard to installing radials on the ground: I used a weed whacker configured as an edge trimmer to make a cut through the grass. Feed the radial wire in the slit and use staples as Bob suggests to secure the wire. In a month or so, the grass grows over the wire and poses no problem mowing.

[Elecraft] On ground - in ground radials
...”Digging in radials does not interest me. Likewise, catching them in lawn equipment is also a PIA. So, here is what I have done and it has worked well”... Tom, WB2KLD” I did something very similar, many years ago, after hombrewing a 40 meter vertical. In order to pin the copper wire radials to the ground, I used pegs, made from wood dowel. I bought some lengths of quarter-inch wood dowel and cut them into 2 inch lengths. One-half inch from the end of each, I drilled a hole, large enough to pass the radial wire. I threaded several pieces of dowel onto each radial wire. As I stretched each wire away from the antenna base, I pounded the pegs into the grass with a hammer. When finished, each radial was stretched tightly to the ground. On uneven ground more pegs are required to cause the wire to adhere to the terrain. Within a few weeks, the radials were no longer visible and I could mow over the radial field. My reason for using wood pegs was that they were non-conducting. Thus, there would be no possibility of electrolytic corrosion or rectification between dissimilar metals. Also, the wood pegs are, over time, biodegradable. The aluminum tubing vertical antenna worked very well, until an ice storm loaded the guy wires so heavily that it failed. The radials are probably still out there.

[Elecraft] Need Mic adapter: Icom SM-50 to K3 mic input jack
It appears that MFJ makes a box, designed to convert one brand’s mic connector to others. It appears to be programmable, using jumpers. I believe the Foster connectors on the K3 or K3S are wired the same as Kenwood’s. The model number is MFJ 1263. I have not used or seen one, so cannot comment on its utility. Gary K0CX I have no microphone for my K3. I am usually on CW or the digital modes. Now I want to get on the KY Phone Net on 3838. So I talked DXEngineering and they know of no adapter plug/cable. So, I have an Icom SM-50 mic and a Yaesu MD-100 mic. Anyone know of an adapter connector that would fit either to adapt them to the K3? Or maybe a universal box that lets me plug all the mic's in and have a cable to the K3 Also run an Icom IC-9700 FWIW.

Re: [Elecraft] Wire antenna ends and spools?
I use extension cord winders (orange in color, from Home Depot, rectangle in shape, about 10 - 12 inches long. Sorry, O can't recall the official name). As for the roped ends, I use glass insulators to fluorescent yellow or fluorescent orange para-cord...about 50 feet worth on each end in order to meet most total distances between trees, buildings or otherwise. I also keep a number of wire ties, velcro straps, small carabiners etc in the "kit". Not sure if this helps.

Re: [Elecraft] KX2 temperature

Re: [Elecraft] KX2 temperature
I guess I misspoke. I have boxes and boxes of "heat sinks" that I've collected thru the years. I use them all the time. I'm constantly looking on eBay for a size or two, for a given project, almost on a monthly basis. I had no idea that after-market heat sinks existed specifically for the KX2. And they look very nice as well! But again, I've never thought to look until I saw this thread. My sincere apologies.

Re: [Elecraft] KX2 temperature
I had no idea heat sinks existed. But, I've never looked, I suppose. Looks like a good idea, but I'm guessing the radio will no longer fit in its case. I ordered a set of heat sinks to try 'em out.

[Elecraft] A or B?
An old friend, who has been inactive for several years, recently purchased a used K3. This is the first transceiver that he’s owned that includes a built in keyer. He has always operated CW with a straight key. He has acquired Vibroplex paddles and wants to know whether to set the radio’s keyer for mode A or mode B iambic. He has never used an iambic keyer or a bug, before. I learned iambic keying with a WB4VVF circuit board, back in the early 1970s, so mode B is what I prefer. I know there are a lot of died-in-the-wool CW people who frequent this list and I would like any opinions as to whether it is easier for a newbie to learn iambic mode A or mode B. I have no clue. Thanks in advance for any advice or opinions that I can pass along.

[Elecraft] Elecraft PA via Generator Power?
Anybody know, or have experience using an Elecraft PA (a 500 watt in my case) with a generator supplying AC power (a Honda 2 KW in my case)? I’ve not done it yet. Wanted to check to see if anyone else has prior experience before I end up blowing the final, or some such. The Honda flavor I have is the inverter styleand they have been known to put out a crappy “signal” at 60 Hz on occasion, not to mention fluctuations due to differing load at different moments.

Re: [Elecraft] K4 whining
Make me an echo of the previous sentiments in this thread. I laid out a full advance deposit shortly after the K4 was announced & there was an ordering ability offered. I chose a fully loaded K4D and am on the request/waiting list for a HD add-on when that is later made available. To me, it's boorish to complain Elecraft hasn't started shipping the K4 out yet, fulfilling orders. Nobody wants the K4 actively shipping more than Elecraft, it's their livelihoods and for us, it is our hobby: Food & shelter trumps fun every day. The whining is childish and makes no sense. You'd think anyone savvy enough to generate the disposable income to buy a K4 would also be savvy enough to know why such whining is useless. Too much QRM. 73, Gary KA1J Looking forward to my K4D on my table, when it's ready. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

Re: [Elecraft] best grounding technique
Many years ago I contracted with Motorola for a large repeater communications system/building to be located at an existing tower facility that was already called home to dozens of other radio systems. The Motorola R-56 standard was the 'bible' they quoted from and used. I have personally used that same method many times since then. It works for me. Your mileage may vary.

A replacement K3S KTCXO3-1 is no longer available from Elecraft. Does anyone have a stable KTCXO3-1, surplus to their needs, that they would consider selling? Even a standard, plus or minus 5 ppm TCXO might possibly be an improvement. There are also some, alleged, KTCXO3-1 oscillator modules for sale on eBay for about 40 bucks.

[Elecraft] K3S KTCXO3-1 possible problem
I have a K3S, purchased factory built, February 2019. This included the 1 ppm TCXO3-1-F option. A few months later, I noticed that SSB signals heard on 50.125.000 MHz all sounded a bit off frequency. Hence, I performed a reference oscillator calibration, using method 2. Because of my relatively short distance to WWV, the variability in the signal strength made its use difficult. Instead, I used a GPS disciplined TCXO as my 10 MHz standard. The GPSDO had been on for several hours before any calibration and the transceiver had been on for, at least, three hours. The frequency display on the K3S was set to 10.000.000 MHz. Beats were displayed on a Weston VU meter, driven by an opamp, connected across the external speaker output. This allows beats to be easily seen, that are less than one per second. The REF CAL as received from the factory was 49.379.766 On 7/10/2019, I changed the REF CAL setting to 49.379.448 (I chalked this change up to possible crystal aging.) On 11/30/2019, the REF CAL setting was changed to 49.379.110 On 3/1/2020 the REF CAL setting was changed to 49.378.926 On 1/16/2021 REF CAL was changed to 49.378.495 On 1/30/2021 REF CAL was changed to 49.378.484 On 2/22/2021 REF CAL was changed to 49.378.508 (the first time the setting has been increased) I have also noticed a change of several Hz in the beat note between the transceiver having been on for half an hour and having been on for three or four hours. This seems odd behavior to me for a high stability, 1 ppm TCXO. The transceiver is in a room, with a temperature of 70, plus or minus, 3 degrees Fahrenheit. There is nothing on top of the transceiver and there is plenty of space below, behind and on either side of the radio. There are no other heat sources near the transceiver. Am I being overly critical, or do you think this is unusual behavior for a KTCXO3-1? I posed this question to Elecraft tech support. The reply did not address my question as to whether this KTCXO3-1 is misbehaving. The reply only said that “We have no KTCXO3-1 and have no orders to restock at this time.” The tech, who replied, also gave me sourcing information for, apparently, the oscillator part on the board. Thanks in advance for any time taken to reply to my post.

Re: [Elecraft] KPA1500 goes into firmware load
Dick has pointed me at the mechanism. I had forgotten that the REM input is fed from the K3 12V output, and that is what turns the amp on. If that input is at 12V when applying 240V, you go into firmware load. So a slight mystery remains, as reported by others, that this sometimes occurs for no apparent reason, at times when we’re "pretty sure" the 240V is already on. When dead-starting and turning on the 240V, I always wait a few sec before turning on the K3 remotely. But sometimes it comes up in firmware load anyway. Thankfully this is always recoverable. FYI: You can also turn on a KPA1500 or 500 by pulsing a line in the Aux bus via a K3 macro. Info on this is on p. 21 of the K3 Remote Owner's Manual.

Re: [Elecraft] KPA1500 ATU band/bin operation
Thanks for the good explanation Dick. It got by me that the bins are storing the ant port# along with the tuner settings. That should work well having 2 antennas on every band if needed. Adding a 3rd might be cumbersome but more then I need for now anyway... I'll think about that later. Thanks for all 3 of your comments good food for thought.

The KPA1500 chooses the most recently stored ATU setting in the new “bin”. On transmission, if SWR exceeds a threshold, and a KPA1500 config choice for HiSWR retune is enabled, other ATU settings in the bin are evaluated. This requires a bit of RF. Once the best ATU setting is found, the bin is reordered and stored, so when you return to this frequency, the most recent setting is tried first. If you mostly use your three antennas on the obvious bands, there should be one or two ATU settings per bin. If you train your 80 meter dipole on 20 and your 40 meter beam on 15, there may be more ATU settings per bin. I’d consider putting the HyTower on the second ant port so that it can be used on all bands without having to search thru settings for the “other” antenna. If there are any ATU settings in the bin, only those settings will be tried, so tune in every bin if you have multiple antennas. It takes on the the order of 20 milliseconds of stable RF per ATU setting, which has to do with relay settle delay and reevaluating SWR. A CW dit at 30 WPM is 40 mSec. ATU relays are changed after bypassing the PA momentarily, and that also takes a few mSec. 73 de Dick, K6KR > On Nov 15, 2020, at 08:51, Gary Slagel via Elecraft > wrote: > > I'm thinking of replacing an old SPE amp with a KPA1500. > I have 4 antennas: 10/15/20 yagi, 40M yagi, 80/160 dipole and an all band > hytower vertical so will probably have 3 switched antennas to one antenna > port on the KPA1500 and 1 antenna to the 2nd antenna port. > After 'training' on all freq/antenna combinations I'll tend to have 2 or 3 > settings for each freq/bin.

[Elecraft] KPA1500 ATU band/bin operation
I'm thinking of replacing an old SPE amp with a KPA1500. I have 4 antennas: 10/15/20 yagi, 40M yagi, 80/160 dipole and an all band hytower vertical so will probably have 3 switched antennas to one antenna port on the KPA1500 and 1 antenna to the 2nd antenna port. After 'training' on all freq/antenna combinations I'll tend to have 2 or 3 settings for each freq/bin. When I tune from one frequency to the next and one bin to the next bin, the tuner will have to select one of the 2 or 3 settings for the bin. Does it wait until I transmit (a dit with the key) to select the new setting or will it track with the k3 and make changes as I move from freq to freq. Will I notice the tuner trying each setting (lights flashing, relay noise) until it finds the correct setting? My older SPE has a similar freq/bin concept but has 4 antenna ports and 1 set of band/bins per antenna port. This allows it to know exactly setting to use which is nice.

DLI does sell a rackmount PDU with 80-240 VAC capability and C-13/C-19 connectors, making it truly universal. I use several of them at my remote sites.

[Elecraft] K3, k4 Black knobs
OK, I operate portable and often at night and lighting has to be managed to reduce critters of the night dive bombing me when operating. Wearing a head mounted light causes the critters to go into a frenzy so does not help. I often wonder what it would be like If the buttons and/or knobs could be either back-lit or maybe they could be lighter in color to help nighttime operation. As it stands, the k3 is very hard to see if i need to use any front controls. Placing a light behind me has worked for me but at times the critters wander away from the light and use me as a target for harassment. Anyone found an alternative to what I have tried?

Re: [Elecraft] K4 Headphones Q
Jim, I only use my Bose QC-35 when: 1. on the cell phone. 2. mowing the yard/tuning my motorcycle 3. whenever using the K3 & K3s. The noise cancelling works perfectly with the blower from the Alpha 77SX right next to me, I only hear what is coming in from the radio. Why your QC-35 does not noise cancel when attached via cord is not normal, mine is a Godsend. 73, Gary KA1J > > I have Bose QC-35 headphones.

Re: [Elecraft] K4 Pricing Posted
Well, let’s think about this one a bit. I for one was not disappointed with the pricing; I think they did a super job. I have a K4D on first-group order for $4700. The new price adds $300. I’m ok with that due to the extreme circumstances involved with getting parts, etc. But there’s another way to look at it. To get a rig from Elecraft pre-K4 such as the K3S, compared with the K4D, you would have to add a K3S SUB RX, synthesizer board, at least one CW or narrow SSB filter (or both), the I/O board for all the antenna connections, a P3, a P3 SVGA option, a P3 TX monitor option, a digital voice recorder. And, I’ve probably forgotten a few, such as the K4’s ethernet connection and all that implies. Throw in the extras offered by the K4D and man this is a great deal. For example the P3 cannot compare with the display on the K4(D). Throw in performance and it’s even better. Enjoy the hobby whatever you choose to get. Fun is the name of the game. 73, Gary W2CS > On Oct 3, 2020, at 12:09 AM, Dave wrote: > > I was disappointed to see the pricing for the K4.

Re: [Elecraft] K4 training
Yes, That's the current way of things. What I suggest would be more like an on-line video operator's manual sanctioned by Elecraft, with logical menu to find the how-to, exactly, the function you want being done. I'm not thinking so much where is the Power Switch, but more like how to determine which thought process to use with the K4/K4D/K4HD to best accomplish commonly used procedures, and then how to get that done. Things like the display will be a bugger for awhile & the picture being worth a thousand words concept is magnified with concise video. Do-it-yourselfers on youtube will not get to the point & will be offering opinions which isn't helpful to the direct question. More, you'll have to use youtube's search engine to hopefully find what you're looking for, and then be subjected to advertisements before and during the presentation. It'll all be sorted out, I'm just thinking the official video how-to would be a real asset to many. Maybe not. 73 & stay safe, Gary KA1J > I AM SURE... > When the first K4 is in the hands of users, that there will be a > "flurry" of YouTube un-boxing videos.

[Elecraft] Antenna tuners
You are in good company with Walter Maxwell, W2DU, now silent key. Maxwell was an engineer at RCA. He designed the antennas on several earth orbiting satellites and the antenna on the Lunar Rover. He explained this quite succinctly in his book Reflections (all three editions), by use of the conjugate matching theorem. As I recall, that chapter in his book (peer reviewed by the RCA engineering department) was called My Antenna Tuner Tunes My Antenna. Gary, K0CX But if the "tuner" is an LC network, like an adjustable L network, T network, Pi network, or a linked-coupled network, then I strongly disagree. A tuner is a 2-port network. A transmission line is also a 2-port network. Both networks obey reciprocity, meaning that what you do to one port of the network will have a direct influence on the opposite end. That being said, if an antenna exhibits a complex impedance at our frequency of interest, and that behavior can be corrected (brought to resonance) by the application of a particular value of reactance at the antenna's feedpoint, then that application of reactance can, for reasons of convenience, be made at the "shack end" of the transmission line. As such, the "tuner" in the shack is really "tuning" the antenna!

[Elecraft] Waterproof SO-239 covers
A similar concoction is readily available in the U.S. Depending on who manufactures it, the brand might be Penetrox, NoAlOx or OxGard. It is used by electricians to enhance aluminum to aluminum and aluminum to copper or brass electrical connections. Each of these products appears to be a mixture of a silicone based grease and powdered zinc metal. I have used such, between sections, when assembling an aluminum antenna. Before assembly, I apply the grease and use emery cloth to shine up the outer part of the inner tubing. I apply the grease to a wire brush made for plumbing and use that to clean the inside of the outer tubing. Aluminum is a very chemically reactive metal. It quickly forms an oxide that protects the surface from further reaction. Unfortunately, aluminum oxide is a pretty good insulator. By using the grease with the abrasion, the oxide is removed and the metal is protected from oxygen in the air during assembly. I find that this procedure prevents inte rmittent connections and makes future disassembly much easier. A friend had a multi band vertical antenna that was really flaky. The VSWR would change with the wind. We took his vertical apart and performed the antioxidant and abrasive treatment. His vertical worked reliably for years afterward. At one time, Mosley used to supply Penetrox with their beam antennas. A good move in my opinion. Gary, K0CX I cover the threads with a mixture of zinc and Vaseline anyway...I still use the zinc and Vaseline on threads though because it lubricates and the zinc helps conductivity a little, but my stock has all but gone.

Re: [Elecraft] K4 in production
I'm always bemused when a completely unexpected series of profoundly affecting variables, none of which are from internal causes, make themselves a factor in development and construction, appear and globally interfere with design, production, and supply. This fluid state appears while a specific completion date and time was never assured of, & in subsequent conversations with advance purchasers. As there was never a promised date, there is a Pandemic where over 100,000 people in the USA alone have already died, Manufacturing globally has taken a real hit, transportation has taken a major blow. I had a USPS 2 day package shipped from Michigan on Sat 11 and it is nor the 16th & tracking shows it just left Michigan on route to CT. It may be here on Saturday. That'll be a 6 day delivery with a 2 day promise. That same kind of delay is happening to the construction of the K4 and any new components are also affected in this way. There is no other choice and I want it And I want It Now pressure doesn't do anything but waste everyone's time. It has zero rate on accelerating production and if anything, detracts from the focus from the principals. All this takes me back to the bemusement I get when reading such comments. Do they really believe in this arena it will move anything along faster, and if the company indeed did rush to complete while not having sufficient components in, on time, that it would behove the production run in any way whatsoever? Good friends, chill, this is an unprecedented time and Elecraft is moving along in the best way to give the best product they can do. We'll have our little beauties when they're vetted and competent. Till then, chill, practice some CW Check the antenna connections stop thinking of it should have been here by now, because it was never promised to be here by now. Things are moving forward nicely. And yes, I dropped the full deposit for a K4D and am aware I'll have to wait for the HD module to be created.

Re: [Elecraft] K4 Books
I second the use of PDF for finding answers. It really helps these old eyes to be able to expand the print quickly after using the search feature to find the word I'm searching for. A searchable PDF does this wonderfully. Another thing that helps me greatly is a video say on youtube that has an outline and an instructor doing certain things with a clear camera view so it's like having an instructor right in front of you & the equipment so you can mirror image what they are doing exactly, to understand. Being able to look on an outline and see for example "Adjusting the noise blanker": 14.45 Meaning at 14 min, 45 seconds, that presentation is found on the video. 73, stay well, Gary KA1J > I solved my issues with understanding Elecraft radios, I prefer all > thee methods of learning to fully know the ins and outs.

[Elecraft] OT Good Source for Stainless Fasteners and
Stainless hardware is commonly used on FM broadcast antennas. Stainless is a bit on the gummy side. When tightened, the threads tend to distort and this can make future disassembly a challenge. Tower crews frequently end up twisting off nuts or bolt heads when replacing damaged elements. If you are going to use stainless hardware, I suggest applying anti-seize lubricant, available at auto supply stores, to reduce seizing and galling. I also suggest never reusing stainless hardware. Replace with new. Gary, K0CX “When using stainless hardware there is very little strength compared to a steel fastener. So the minimum strength needs to be confirmed. You don't want the bolts to shear and topple over. Please be careful to get the right grade bolts. You will not get what you need at a hardware store or a tractor supply.

[Elecraft] K3s discontinued?
Was there a reason why the K3s was discontinued? Looking at the pricing for a K4 was a shock in itself, when I did the numbers to convert to AUD I was floored. That is one great beast BUT too far out of my price range sadly. As one who normally does not buy unwanted used equipment, I was hoping to add a K3s to my current setup (K3 #679) but that appears to be out of the question dammit.

When I added my furnace, I made it part of the purchase contract that there was to be no new RFI. This makes the vendor very careful. Tell them it is a showstopper, and they will be responsible for RFI removal if RFI comes with the new purchase. Get it in writing if possible. Insist they call the manuafacturer and ask about RFI for the unit you are considering, and are there RFI kits for that unit, PRIOR to your purchase... Be careful assuming brand and model numbers will remain RFI quiet over time. Vendors change parts, and circuits, within a fixed model number all the time... What is RFI quiet today, may not be RFI quiet tomorrow... Take measurements first, before the install, and after install. Use this process: https://www.nk7z.net/sdr-rfi-survey-p1/ It is part I of III in a series on using an SDR to model your RFI environment. Perform the tests, save the results, then run them all again after install... I run a full sweep once a year here, and keep the results... Also see my March 2020 article in CQ on this subject...

Re: [Elecraft] Quiet Ductless HVAC System
At our remote site, we have a new Mitsubishi 12000 BTU mini-split. It is located right under our 30 ft tower with Yagis and wire antennas. There is no detectable elevation of the noise floor nor any buzzing birdies on 160 thru 2m. An external thermostat adapter was installed, and on the cable to the thermostat I did apply a proper choke, just in case. All AC wiring is in Sealtite or EMT conduit. Exact models are MSZ-GL12NA-U1 - indoor. MUZ-GL12NA-U2 - outdoor. -Gary NA6O > > Does anyone have suggestions for an RF quiet ductless, also called a "mini > split" heat pump system.
