Pactor (as used by Winlink) is less critical. Computer based transceivers can have slow change over due to long latency times. My K3 and my Icom IC-7300 are fine on Amtor (and Pactor). I have a KX3 but haven?t tried it. The ARRL review T/R speeds of the IC-7300 are 15/14mS, the KX3 is 44/30mS. The K3 with sync data mode was 22mS in the April 2008 QST review. No idea about the K4 though. 73 Dave G4AON -- Sent from my iPhone SE From mike.flowers at gmail.com Sat May 1 10:45:45 2021 From: mike.flowers at gmail.com (Mike Flowers) Date: Sat, 1 May 2021 07:45:45 -0700 Subject: [Elecraft] K3 / KXV3A / PR6 / SteppIR 3L - 6M Operation Message-ID: <005601d73e98$ab756e70$02604b50$@gmail.com> Hi Folks, I recently purchased a used PR6 6-Meter preamp in anticipation of the upcoming 6M summer season. My K3 has the KXV3A Interface option installed. I have a K-Line station; K3,P3,KAT500,KPA500. My 6M antenna is my SteppIR 3L. I've downloaded the PR6 and KXV3A manuals, and I'm reading the Elecraft K3 Owners manual and Fred Cadys K3 manual to understand the signal path for the proper use of the PR6 preamp. This is the first time I've needed to use the RX ANT feature on the K3, and there are a lot of ways to configure the signal path in the K3, I've discovered. My 6M operation is pretty simple. The SteppIR gives me a 3L yagi on 6M. I have the KAT500 configured to recognize the SteppIR as a resonant 6M antenna on ANT1 and the KPA500 gives me a full 500W if I need it. I'm looking for guidance for using the PR6 in this configuration, and I will appreciate any suggestions and cautions about how to effectively use the PR6 for my 6M operation. Thank you in advance for your help! - 73 and good DX de Mike, K6MKF, NCDXC Secretary From repair at willcoele.com Sat May 1 12:45:17 2021 From: repair at willcoele.com (wa9fvp) Date: Sat, 1 May 2021 09:45:17 -0700 (MST) Subject: [Elecraft] KPA500 Relay Failure Message-ID: <1619887517834-0.post@n2.nabble.com> I'm repairing a KPA500 for a friend that has the RX loss in standby mode. After a time, he also lost receive in operate mode. After doing a teardown, I found the problem. With the PA board removed, I checked K23A relay. The normally closed contact on the antenna side of the relay was open. K23B was OK. With relay on the board, there was no safe way to energize the relay so I didn't check the contacts on the normally open side. I also noticed that resistor R7 was un-populate and pieces of it was stuck to bottom cover. Looking at the PA schematic I came to the conclusion that the relay K23A was also having problems on the operate position. With no or a poor connection to the antenna, the 500-watt output voltage can go sky high. It can get rectified by D9 and feed a high DC voltage through L4 and damage resistor R7 or even un-solder itself. I replaced the relay and R7. I remove the cover on the old relay and using a 12v power supply, I set up bench test. With the relay energized, I connected a Fluke meter in diode mode and it proved that the antenna connection in operate mode was intermittent. ----- Jack WA9FVP Sent from my home-brew I5 Core PC -- Sent from: http://elecraft.365791.n2.nabble.com/ From wes_n7ws at triconet.org Sat May 1 12:51:41 2021 From: wes_n7ws at triconet.org (Wes) Date: Sat, 1 May 2021 09:51:41 -0700 Subject: [Elecraft] KPA500 Relay Failure In-Reply-To: <1619887517834-0.post@n2.nabble.com> References: <1619887517834-0.post@n2.nabble.com> Message-ID: Good work.

I'm not sure if I caused other issues when I swapped the boards, so if you hear me on, drop me an email to let me know how its sounding. The older board doesn't have the metal plate stiffener on it, nor does it have the 2010 mod. Meanwhile, I'm in the market for a K3SYN board.

I think it makes the 3 element antenna a 4 element antenna on 6 meters and greatly improves the F/B ratio and adds a small gain. I have not added this to my Yagi, since I seldom have operated on 6 meters, but it looks like it may be possible to add it to the boom from the top of the tower without much trouble since it is not too far out from the mast. At one time I think the cost was less than $100, but probably you could build your own element if you have aluminum scrap antennas. Just an idea, since every dB helps.

KD5ONS - There was three kings unto the east, Three kings both great and high, And they hae sworn a solemn oath John Barleycorn should die. They took a plough and plough'd him down, Put clods upon his head, And they hae sworn a solemn oath John Barleycorn was dead. But the cheerful Spring came kindly on, And show'rs began to fall; John Barleycorn got up again, And sore surpris'd them all. The sultry suns of Summer came, And he grew thick and strong; His head weel arm'd wi' pointed spears, That no one should him wrong. The sober Autumn enter'd mild, When he grew wan and pale; His bending joints and drooping head Show'd he bagan to fail. His colour sicken'd more and more, He faded into age; And then his enemies began To show their deadly rage. They've taen a weapon, long and sharp, And cut him by the knee; Then tied him fast upon a cart, Like a rogue for forgerie. They laid him down upon his back, And cudgell'd him full sore; They hung him up before the storm, And turn'd him o'er and o'er. They filled up a darksome pit With water to the brim; They heaved in John Barleycorn, There let him sink or swim. They laid him out upon the floor, To work him further woe; And still, as signs of life appear'd, They toss'd him to and fro. They wasted, o'er a scorching flame, The marrow of his bones; But a miller us'd him worst of all, For he crush'd him between two stones. And they hae taen his very heart's blood, And drank it round and round; And still the more and more they drank, Their joy did more abound. John Barleycorn was a hero bold, Of noble enterprise; For if you do but taste his blood, 'Twill make your courage rise. 'Twill make a man forget his woe; 'Twill heighten all his joy; 'Twill make the widow's heart to sing, Tho' the tear were in her eye. Then let us toast John Barleycorn, Each man a glass in hand; And may his great posterity Ne'er fail in old Scotland!

Yes, if you can't afford (or can't rig) a dedicated 6M antenna, the 3-el with the added director is a decent, but not great, antenna. I had a lot fun with it.

I remodelled it and I was able to improve a number of things and posted the measurements on my QRZ page if you are interested. Not only did it model better it performed better and loaded better as the SWR was lower. A bunch of my friends tried it and they were pleased with it as well. In my design, you can make the changes to a steppir on a tower if you can reach your passive 6M element. You don't have to order any parts to make this work. This was for the 3EL Steppir.

The key to making the SteppIR antennas anything more than pathetic on 6M is adding a fixed reflector. Some in the group have modeled and developed 6M antennas on the same boom that rival commercial monobanders on the same length using only the original driven element as being adjustable.

It was a s/n 8xxx with the old synthesizer. I first noticed "dead spots", primarily on 40 and 160. These dead spots would be a specific point. There were several and they were repeatable. I got some reports of bad chirps and figured out that the chirps were only when I was very close in frequency to one of the dead spots. I bought a new K3SYNA (which I was going to do anyway) and everything was fine. I never did any further failure analysis, eg swapping the "bad" syn into other radios, etc. greg/na8v you wrote: Let me give this another try.

It's inexpensive and Teflon insulation. I bought 2000 ft of #18 last week for work and it's right at 12 cents a foot. It doesn't melt when you solder to it and is easy to work with. The 22 AWG I normally buy is 3 cents a foot. We buy from Wiremasters south of Nashville in Columbia TN. $50 minimum order but no minimum on wire lengths. So you could buy as many feet of each gauge and color as you would like. Normally for home use I buy a thousand feet of a size/color at a time. When I started my work was buying the wire from Digi-Key and it was $60 for 100 ft spool. They no longer do and didn't know about other supplier. I can connect anyone interested with the rep there I use.

I've done this at least once per day for the last several years. This time, however, I heard arcing from the Astron's on/off switch. Then I saw that the KAT500 LED was blinking constantly about 3 times per second. After doing some troubleshooting, I replaced the power supply switch with one I had here but the tuner's LED kept blinking and the unit would not respond to any key press, including the power button. I tried connecting the KAT500 to the computer but there was no connection to be made. Then the blinking changed frequency and got faster. Eventually, I was able to connect and reload the KAT500 firmware and everything has been OK since. I do have the KAT500 connected directly to the power supply since I am powering a P3 and a PR6-10 from the K3's aux power connection. I noticed that, normally, all the LEDs in the KAT500 would blink momentarily as the power supply was turned on even though I have the KAT500 set to power-on in the "off" position. Then it would power up and work fine. Anyway, sorry for the verbage, but my theory is that the bad on/off switch in the Astron corrupted the firmware in the KAT500. I don't know what the blinking "man" LED meant, and I don't know why there were 2 different blinking speeds. I built a little switch box to keep the KAT500 power disconnected while the power supply comes on and settles down so as not to have another problem in the future. (Marlin P Jones sells an in-line power on/off switch with a 2.1 mm barrel plug on one end and a 2.1 mm barrel socket on the other end. I would have used that except I cannot normally reach the back of the KAT500 in my configuration). 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ From jim at audiosystemsgroup.com Mon May 3 20:30:05 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 3 May 2021 17:30:05 -0700 Subject: [Elecraft] KAT500 Blinking "MAN" LED - Bad Astron P/S On/Off Switch In-Reply-To: <1620083233962-0.post@n2.nabble.com> References: <1620083233962-0.post@n2.nabble.com> Message-ID: <6d45b8fe-ec1e-a03a-3398-d2fa8dd885b5@audiosystemsgroup.com> On 5/3/2021 4:07 PM, John W2XS wrote: > The other day I turned on my Astron RS-35M and then my K3, P3, KAT500, and > KPA500.

Every Astron I've checked had a manufacturing defect that fails to bond AC power line green wire to the chassis, thanks to paint under the lug to which it was soldered. In addition, the V- terminal is soldered to the same lug, connecting it to the green wire, but not to the chassis. I suspect that when the switch broke, it put some voltage on V- and failure to bond stuff properly in the shack coupled some voltage to the KAT500. 73, Jim K9YC From n6tv at arrl.net Mon May 3 21:24:14 2021 From: n6tv at arrl.net (Bob Wilson, N6TV) Date: Mon, 3 May 2021 18:24:14 -0700 Subject: [Elecraft] [K4FT] K4 software release 13 In-Reply-To: <5AF2F6C2-BC2F-45B4-9D61-29CB7F66A6D0@elecraft.com> References: <5AF2F6C2-BC2F-45B4-9D61-29CB7F66A6D0@elecraft.com> Message-ID: Installs fine.

I've copied the detailed problem report below. I didn't have that problem until I tripped it during some experiments today, and through experimentation I have some additional data points. In my case, I am using the latest KX3 code available now (2.95/1.52), using the KX3 2m transverter (that converts to 6m) to tune a signal on 10 GHz: XV6 on XV6 RF 10489, or 89, or 489, or 9, doesn't matter XV6 IF 50, or 28, doesn't matter XV6 PWR 0.1 XV6 OFS 2.3 (Drew had 1.2 in his bug report) XV6 ADR int.trn0, doesn't matter The key is the OFS parameter. Set it above 0.66, so 0.67 or higher, then when shutting down the KX3 and switching back up the buzz problem happens. Setting the offset to 0.66 or lower and the problem isn't there (the problem isn't there all the way up to -9.99 kHz offset), but set the offset 0.67 or higher, then the buzz problem happens. I guess I didn't see this earlier because most of my SHF gear is GPS locked. For this experiment, I didn't, but clearly one can't use the xverter offset feature on the KX3. We now also know for sure that this isn't a radio-specific issue or defect since it reproduces on multiple radios. Since some of my bugs reported earlier produce both on K3 and on KX3, I tried the same problem on K3 - for this specific probleme, it doesn't have the issue, it is KX3 specific. I do hope that Elecraft will, at some point, step away from the KX4 chaos and spend some time to address these outstanding problems on older platforms. For one, they have been reported for years, and since source code isn't available, we have no other option to get this fixed. Since the K4 also is a software radio, abandoning software update (for the KX4 or K5?) really reduces the value of the product. And I think that fixing these bugs can be done in full corona lockdown. I've added the bugs I know to github (https://github.com/drewarnett/kx3-firmware-issues/issues) Since Drew's report is old, I'm copy-ing it below for reference. Geert Jan --- Drew Arnett Wed Aug 19 10:49:08 EDT 2020 Hi, Weird problem. Anyone else try this and do or don't see this? Just got my KX3 back from repair. This included an upgrade to the latest firmware. (Makes sense. Requirement for production test. I hadn't upgraded to the very latest, because I had no need for the latest improvements.) Set the radio back up for 10368 to 50 MHz transverter use on XVTR1 band. Now, if I power up the radio when it was shut down on the XVTR band, there is a crazy loud buzz on the audio output (and corresponding response of the S meter.) If I switch to any other non-XVTR band and then power up, no problem even if switching then to the XVTR band. FW is now 2.90/1.52I got the radio back just before the 10 GHz contest, so only made minimal changes to settings from the cleared state it came back in. Changes made: AFX mode off (was delay) ATU bypass (can't remember if it came back this way or not. XVTR is good 50 ohm load.) BAT CHG off (was not inst) BKLIGHT off (was on) MIC BIAS off (I think came back on; used dynamic mic during contest) MIC BTN Ptt (was up/down) TX DLY 10 (was 5. abundance of caution as 5 is more than enough for the 10 GHz rig I'm running) XV1 on XV1 RF 10368 XV1 IF 50 XV1 PWR 0.1 XV1 OFS (set in field) 1.20 XV1 ADR trn1 set the clock. :-) turned on the hidden in the menus CW-in-SSB feature I know I turned on or off a couple of front panel things as they left it. Don't remember. Stuff like vox, pre, nr or nb. Definitely adjusted mic gain and compression and keyer speed. :-) RX ISO changed to on during the contest, but problem occurs with it on or off What does the headphone jack output look like? Power up in bad state. Set volume control to 20. With no load other than 10X scope probe, the AC component is identical for left and right. Tip has about 0 V DC offset. Ring has about + 0.5 V DC offset. AC component looks like a the differential of a square wave. Peak to peak amplitude is 220 mV. (This follows volume control. Didn't check to see if DC offset follows volume control.) 12.2 millisecond repetition rate for positive and negative pulses. Negative pulse leads positive pulse by 2.2 ms, so 10 ms from positive pulse to negative. Very small AC ripple on that with a period of about 0.4 ms. I was very happy to find a sequence to avoid the problem (as described above.) To trouble shoot, I tried to rule out a number of things. Unplugged ALL cables from the KX3. That did not resolve. Tried external 12.4 V (battery on hand) and internal battery removed. Tried internal battery (charged) and nothing plugged in. No dice. Given that it's just back from repair, that sequencing gets it in a bad state, FW was upgraded to a new version, and audio path goes through FW, seems reasonable to ask if this is a known FW issue or if someone can try to reproduce this. Hoping to figure this out before the Sept VHF, the Sept 10 GHz contest weekend, and of course the HF contests coming up later this fall. :-) With my workaround, I was able to participate in the Aug 10 GHz weekend without interruption. I ran a W1GHZ XVTR barefoot (+5 dBm Pout) for best DX of 379 km. How much fun can you have with a KX3? Lots! :-) Thanks and best regards, Drew n7da From jmdriskell at msn.com Fri May 7 18:50:20 2021 From: jmdriskell at msn.com (James Driskell) Date: Fri, 7 May 2021 22:50:20 +0000 Subject: [Elecraft] Wall st journal article about dxpeditions In-Reply-To: References: Message-ID: It would have been fun to read the article but it's behind a paywall. 73, Jim Driskell W7OWI ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of Tony Estep Sent: Thursday, May 6, 2021 20:55 To: Elecraft Subject: [Elecraft] Wall st journal article about dxpeditions Complete with a pic of a K3. https://www.wsj.com/articles/post-pandemic-travel-for-ham-radio-fans-as-far-away-as-possible-11620312400?st=vb0vgz9a268gjgk&reflink=article_copyURL_share 73, Tony KT0NY ______________________________________________________________ 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 jmdriskell at msn.com From clawsoncw at gmail.com Fri May 7 19:50:41 2021 From: clawsoncw at gmail.com (Carl Clawson) Date: Fri, 7 May 2021 16:50:41 -0700 Subject: [Elecraft] K2 #7997 is alive Message-ID: I'm 20 years late to the game but I finally built a K2.

The main receiver is between 6 and 8dB worse than the second receiver. The stupid thing about it: it is not always like that, but the poor sensitivity comes sometimes creeping or sometimes suddenly. It seems to have something to do with the transmit / receive switching. I checked this very carefully with an HP8664A signal generator and a spectrum analyzer. Sometimes both receivers are exactly the same, then the main receiver slowly gets worse and worse (within a minute the amplification drops by 6-8dB) sometimes it happens immediately after switching from RX to TX and back. Then it happens that after switching from RX to TX and back again, both receivers are the same again. It can also happen that the main receiver is initially 8dB worse than the second receiver, but without RX / TX switching the missing 6-8dB are suddenly there again - in the middle of receiving mode, without switching. So it's intermittent and it drives me crazy not to find out what's going on. Is that another bad pin diode somewhere in the main receiver and if so: which one? Maybe someone has an idea? Help is very much appreciated. This is a K3 #56xx with all features and all upgrades so its more or less a K3S rather than an K3. 73 Udo, DK5YA From pa2a at xs4all.nl Sat May 8 07:59:03 2021 From: pa2a at xs4all.nl (pa2a at xs4all.nl) Date: Sat, 8 May 2021 13:59:03 +0200 (CEST) Subject: [Elecraft] KPA500-KAT500 tuning settings In-Reply-To: <747423459.373338.1620475014313@webmail.xs4all.nl> References: <747423459.373338.1620475014313@webmail.xs4all.nl> Message-ID: <1147289774.373491.1620475143144@webmail.xs4all.nl> Hi, if I switch the KPA500 with the band buttons to another band I would expect the KAT500 to follow the last tune settings on the new band.

It worked first time but was intermittent. I found the issue as I had omitted to solder the outer top pins of the twin three pin interconnects. That done everything seems ok and then........ No Apparent RF output. USB/LSB/CW Pressing TUNE produced a max of 0.8W. VOX would trip to transmit but the S meter showed no modulation. Coarse carrier balance adjustment worked but zero S meter readings was very wide (unlike earlier when it was a fine, narrow adjustment) All voltages looked slightly low but ball park on the KSB2 board except for U2 (the DAC) Pin5 which is ALC THR. This was sitting at 5.89v rather than 0.6 on both RX and TX. I have removed the KSB2 and full CW power output can now be achieved which is a relief. I will examine everything under a microscope again but has anyone any suggestions? I suspect ALC to be the culprit but how to investigate?

The KAT500 can auto-track any Kenwood or Kenwood-compatible rig that outputs frequency data in the format: "FA00014025000;". Connect the RS232 RXD line (Pin 2) of the Kenwood rig to the TXD line (tip) of KAT500 PC DATA connector, with no connection on ring. You have to use the BR; command to set the baud rate of the KAT500 PC DATA jack to match the rig's RS232 baud rate. You can also uise a program like N4PY Pegasus Plus to keep the KAT500 / KPA500 in sync. with the rig. The S-BOX-USB provides either capability using standard commercial stereo and serial cables, with parallel wiring to all logging programs and the KPA500 XCVR SERIAL connector, so no splitters or custom cables are required. If you're using a TS-590S with a working USB port, you can connect the computer to the USB port and connect both the KPA500 / KAT500 to the TS-590S COM port with such wiring (only wired RXD in parallel, never TXD). Modern Yaesu rigs do not output enough digits of information in the FA command output (they drop most of the leading zeroes). The KPA1500 firmware can handle the Yaesu format of FA frequency data to auto-track, but the KPA500 and KAT500 cannot, though they could potentially be updated to do that. 73, Bob, N6TV https://bit.ly/S-BOX On Sat, May 8, 2021 at 4:59 AM wrote: > Hi, > > if I switch the KPA500 with the band buttons to another band I would > expect the KAT500 to follow the last tune settings on the new band.

Even if the KPA500 was sending band info to the KAT500 it wouldn't be much use because KAT500 antenna and tuning solution selection is based on frequency not band. Having the KPA500 and KAT500 tune before transmit requires something to send TX band data to KPA500 and TX frequency data to KAT500. Following Kenwood FA is a weak (in my opinion hopelessly unsatisfactory) solution since split operation usually has VFO B as the TX VFO. Elecraft has been asked to revise the KAT500 firmware so it properly extracts TX frequency from IF, FA, and FB just like KPA500 and KPA1500 do. I don't know when/if that update will be available. 73, Andy, k3wyc From wes_n7ws at triconet.org Sat May 8 17:42:06 2021 From: wes_n7ws at triconet.org (Wes) Date: Sat, 8 May 2021 14:42:06 -0700 Subject: [Elecraft] KPA500-KAT500 tuning settings In-Reply-To: References: Message-ID: In answer to the last question I would expect, never.?

Plug and play cables and plus some menu configuration seems pretty easy to me, if you have a Kenwood rig. IMHO, the KAT500 and KPA500 *is* very easy to use with Kenwood radios, with VFO A auto-track, once connected property. It's all well documented in the KAT500 Owner's Manual (pages 16 - 18), and Elecraft can supply KPA500/KAT500 interface cables for a long list of non-Elecraft transceivers, listed here: https://elecraft.com/products/75-discount-on-a-kpa500-kat500-power-combo The S-BOX can provide plug and play interfaces in more complex environments, when you need even more devices connected to the Kenwood serial port, such as SteppIR controllers and Bandmaster band decoders. Some combinations (Icom, Yaesu) do not provide frequency auto-track with just cables, though Yaesu support should be easy to add to the KAT500 / KPA500 firmware since they've already done the code for the KPA1500. In the meantime, N4PY Pegasus Plus software can transform any supported transceiver's frequency into Kenwood format for the KAT500 as well, plus there are Icom/Yaesu/Kenwood translating hardware solutions available in some microHAM devices such as the MK2R+. 73, Bob, N6TV https://bit.ly/S-BOX From glcazzola at alice.it Sun May 9 13:38:46 2021 From: glcazzola at alice.it (IK4EWX) Date: Sun, 9 May 2021 10:38:46 -0700 (MST) Subject: [Elecraft] Elecraft CW keying mistakes using bugs - semiautomatic keys Message-ID: <1620581926927-0.post@n2.nabble.com> Dear friends, Elecraft K3S owners, now I am sure that the K3S is a CW transceiver suitable only for the use of paddles with its internal keyer or external pc keying.

There is and has been certainly a problem with the key input circuit on the K3S. I hope that the same design and construction error will not happen again on the K4 Elecraft.

If the KPA500 isn't tuned on, then the tuner is dumb.? IIRC (it's been awhile), turning on "AI" auto information on the TS-890 fixes this but introduces the problem that trying to use the "CW-T" (CW auto tune) feature on the '890 sends the KAT500 into never-never land.?

The AUXBUS line (pin 2) in the AUX cable provides notification to the K3 as the amp switches from standby to operate, so drive power can be adjusted automatically AUXBUS also lets you use the band buttons on the KPA500 to change bands on the K3, which most folks find much more convenient than cycling through the band up/down buttons on the radio. 73, Bob, N6TV On Sun, May 9, 2021, 12:04 PM Jim Brown wrote: > On 5/9/2021 11:53 AM, Wes wrote: > > Some will argue that r-f sensing works, which is true if you want to > > transmit.

The dit contacts of bugs can be somewhat sketchy/scratchy. There's very little pressure pushing the contacts together when they first make.? It's a common problem on many rigs with many bugs. One fix that's been around forever (predates 555 timers and transistors) is a little arm that preloads the dit spring.? That's a mechanical fix that can work very well.

Not true. The K3 can easily be used with a straight key, plugged into the KEY jack. 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 louandzip at yahoo.com From louandzip at yahoo.com Sun May 9 15:40:33 2021 From: louandzip at yahoo.com (Louandzip) Date: Sun, 9 May 2021 19:40:33 +0000 (UTC) Subject: [Elecraft] K2 #7997 is alive In-Reply-To: <8c4760e5-586a-f1d7-88a1-3080dc2de9c1@k0dxv.com> References: <8c4760e5-586a-f1d7-88a1-3080dc2de9c1@k0dxv.com> Message-ID: <2014727116.1224825.1620589233760@mail.yahoo.com> Totally agree.?

Over 700 contacts in the log for the Straight Key Century Club. Some of those contacts were with different tube/boatanchor xmtr or QRP rigs, but the majority with the bug. I've not used a paddle since Oct 2019. I have had no issue with those two bugs, nor any other bug that was in short service in that time. No de-scratcher used, no capacitor across terminals. Stock, as-is. So it might make sense for any bug user to check setup of pendulum/contacts etc, apply some DeOxit or run thru some fine paper between the contacts. But I don't see any presence or absence of any circuit in the K3 required generally. I do use a straight key sometimes, but the above numbers are the telling sample. On my BA rigs, I do employ a simple keyer in-line with the bug in Straight Key mode, but only to provide a side-tone for xmtrs without side-tone generation.

And I use a Heil mic or a Kenwood MC60 and I get great audio reports. Not to make Wayne's ears burn - but, personally, I think the K2 is an absolutely brilliant design. Of course the K3 is also and no doubt the K4. But to design a kit that anyone handy with a pair of snips and a good soldering iron can build on a kitchen table - that's a special brilliance.

I built my KPA100 15 years ago or so and only recently I investigated updates. The KPA module has seen a number of design updates over the years and it makes sense to investigate. I've updated mine (thanks QRP-shop for getting the mod kits in Europe, through Corona times!) and at the end of a long evening I have a bag of swapped-out parts and a PA that worked quite a bit better, feels like a new unit. I have not used one of the upgraders (being in Europe, postage and customs would probably have me mortgage the house, frankly) but I do recommend updating. It is too bad you don't have the setup to do it yourself because on K2, these mods really are simple and can be done on the kitchen table.

I've had some nerve damage in my dominant hand. I can barely sign my name. Fortunately, I can still type pretty well. So.... Is there anyone that would be interested in performing this mod on my K2?

I think we are working in a similar relationship, except Gary was still employed by Elecraft, and I am now fully retired - I do that on a volunteer basis and my love for the Elecraft products. I still have my K2/twins SN 0020 (fully upgraded), my KX3 (the first one shipped - there was a photo of Lisa chasing down the USPS driver) SN 00020, and my K3 SN 00020 are in the hamshack. OK, my matching Serial Numbers were by request and Elecraft responded positively since the SNs had not yet been assigned.? The original K2 SN was assigned at random - 1 chance in 100 and I got 0020 in that draw. 73, Don W3FPR On 5/9/2021 6:12 PM, Dave Van Wallaghen wrote: > Wel Don, I don't know about all that.

You could also use RG58 if that is better for you. It does not have to have the high voltage ratings of RG8, and RG58 is more flexible than RG8X.

Cable loss for RG8 is about 1.6 dB / 100 ft at 50 MHz. Cable loss for RG8x is about 2.5 dB / 100 ft at 50 MHz. Cable loss for RG58 is about 3.3 dB / 100 ft at 50 MHz. So 2 ft of each would be 0.03 dB or 0.05 dB or 0.06 dB, all insignificant. Connector loss is on the order of .1 dB per connector. So, more important will be the quality of the connectors and the quality of the cable shielding. I use way better cables than required, so I would not be a good reference point, but I use a lab quality RG58C/U cable containing a stranded center conductor (for flexibility) with two BNC connectors and an adapter between my KX3 and amp. Don't buy cheap no name cables from Amazon or eBay. 73, Mark W7MLG On Sun, May 9, 2021 at 3:49 PM wb0m at flashdog.us wrote: > Hi Everyone, > > Quick question: Should the coax from the KX3 to the KXPA100 be RG-8x or > RG-8 (or the equivalents).

If your K2 is below SN 3000, then the K2ATOB mods are applicable - download the K2ATOB instructions for a list of all the mods are required. If your SN is below 2560, I recommend replacing the IF crystals for a better IF filter response. Those steps will bring it up to date except for the K2 Keying Waveshape mod which is currently not available from Elecraft as a kit.?

It's an auto antenna tuner, with memories that, hopefully, have been trained. So it's no trick to tune the rig to 10M, hit a dit to recall that memory, tune around (or study the waterfall if you have one), and either stay there or tune the rig back to where you were, hit another dit to recall that memory, and you're rolling. I have an SO2R station, with multiple antennas and auto-switching of many of them based on band-data. So it's no trick to listen on the other radio. And I also have other RX antennas I can use. Each of us builds as much of a station as we want and can afford and/or have the energy and space for. Even on a Chicago city lot, I had two tri-band dipoles for 20-15-10 (one with traps, the other a fan), and another loaded dipole that I could use on 40, 80, 160, and most of the WARC bands. None were higher than 40 ft. 73, Jim K9YC From kevinr at coho.net Mon May 10 00:56:28 2021 From: kevinr at coho.net (kevinr) Date: Sun, 9 May 2021 21:56:28 -0700 Subject: [Elecraft] Elecraft CW Net Report Message-ID: <2ec75b62-781a-338e-7115-ebc045038403@coho.net> Good Evening, ??

Any time you use a KAT500 with multiple antennas connected, and you also use a KPA500, you run the risk that the band change RF blip will fault the tuner, or the amplifier, or both. This happens because the RF pulse gets to the amplifier before the antenna is changed. This problem is not seen if the antenna is switched by an automatic antenna switch separate from the KAT500. The problem can be easily avoided by having KAT500 and KPA500 follow the TX VFO when the transceiver is in receive mode. Kenwood (at least the TS-590) does not restrict which VFO is used for TX or RX. In simplex operation either VFO can be in use. For split operation either VFO can be the RX VFO and the other is the TX VFO. Kenwood also allows memory channels to define TX and RX frequency. Memory channel frequencies do not influence FA or FB. They only change IF. Following Kenwood VFO A is, as I said before, a weak solution. Elecraft has known for years how to use Kenwood IF, FA, and FB to extract the TX frequency regardless of which VFO is in use. It's done in KPA500 and KPA1500. I still hold onto some fading hope that, when K4 demands less development attention, Elecraft will release a firmware update for the KAT500. 73, Andy, k3wyc From dave at nk7z.net Mon May 10 12:49:04 2021 From: dave at nk7z.net (Dave Cole) Date: Mon, 10 May 2021 09:49:04 -0700 Subject: [Elecraft] Microphone Jack Cover In-Reply-To: <56329D39-7520-4F6A-83DE-7CABA58BCFAE@mchsi.com> References: <56329D39-7520-4F6A-83DE-7CABA58BCFAE@mchsi.com> Message-ID: Why not use a metal cap from American Radio Supply?

Written language is poor at transmitting nuance. If I had such a printer I might consider making a cover. But I don?t and I too live in a less populated area and the closest person I know who has a printer is in Arizona. I am long retired and soon will need to be moving out of my house. I have no professional reason to support the purchase of a 3D printer and before long I would be needing to get rid of it anyway. So for me the obvious choice is to buy a cover. And I prefer chrome anyway. I think my question of why is legitimate and was answered satisfactorily by W0EB in a private email. I will admit that my comment on 3D printers may have seemed a bit harsh. However, I don?t see them as common as he does (it would be interesting to know what percentage of hams have one) and examining my own life, short of having a business that supports one, I find it hard to see the economic value for the average ham to have one. My lack of Ideas does not mean there are not compelling uses. In fact I would love to hear from other hams as to how they have found a 3D printer useful especially for problems for which no other solution is available. Again sorry if you felt offended.

The amp follows the radio, no problem. Very slick. I also have a TS-590SG that I can use as a second receiver for the TS-890. For this to work right, the sub RX needs to connect to the 890 via the serial port with a null modem cable and set to a 115,200 baud rate. Is there a simple way to get the band data to the amp while the 2 radios are connected to each other as described above?

Does the Sub receiver also suffer when sharing the main? There is a 3db splitter when you share the main antenna, so you should see that drop in both receives. When the sub is on AUX antenna, it is using the coax straight out the back of the sub receiver to either the Aux BNC or to the ATU where it would use the OTHER antenna (from the main). So, when the Sub is using MAIN, is it also down? The 3db splitter is on the little Sub-In board at the back of the sub receiver, there could be a bad connection there, the relay or solder on the little wires to the transformer, or cracked solder joint on something like the little black choke-coil. If both suffer when using the main, it could also be D25, just shotgun replace it. Look for damaged parts on that little daughter board next to D25, BSF (Band Stop Filter). It could also be something on the KXV3 transverter interface, you can pull and put two jumpers per the silkscreen. If it has the old single 3-legged D5, shotgun replace that.

The amp follows the radio, no problem. Very slick. I also have a TS-590SG that I can use as a second receiver for the TS-890. For this to work right, the sub RX needs to connect to the 890 via the serial port with a null modem cable and set to a 115,200 baud rate. Is there a simple way to get the band data to the amp while the 2 radios are connected to each other as described above?" Does the TS-590SG/TS-890S absolutely have to be 115,200? The KPA500 maximum data rate is 38,400. If the TS-590SG/TS-890S link will work at 38,400 then it may be possible to pick off IF, FA and FB with a Y cable. I don't know what subset of CAT commands is used when a TS-590SG is used as a second receiver so it may not be possible even if the interface does work at 38,400. Of course other options are available if an intermediate PC or smart controller can be used. 73, Andy, k3wyc From a.durbin at msn.com Mon May 10 15:45:24 2021 From: a.durbin at msn.com (Andy Durbin) Date: Mon, 10 May 2021 19:45:24 +0000 Subject: [Elecraft] KPA500-KAT500 tuning settings In-Reply-To: References: , Message-ID: "Kenwood rigs have master/slave menu options designed to enable one Kenwood rig to follow the frequency of another. ?The KAT500 manual recommends enabling these options, but I cannot confirm if they affect the frequency reported by the FA; command. ?If you have a null modem cable, can you please connect it to the TS-590 COM port when these options are enabled, and report what gets output when SPLIT is ON?"

I would check relay activations on the input and output sides of both the BPF and LPF 10/12 meter filter sections to be sure that those filters are being selected. You should try to listen on 10 and 12 meters if you have an external signal source (signal generator or another transmitter into a dummy load with a length of wire for a RX antenna near the dummy load) for those bands - are you able to hear a test signal? And the most obvious suggestion, which I would check first: do you have the proper antenna port selected on the front panel? (ANT 1 or ANT 2) The antenna port selection is band-specific.

I've got a 3d printer. I used it a bunch a year ago. Now, the only thing that keeps it from becoming a coat rack is that it's nowhere near where the coats are. Not because I don't see good uses for it -- heaven forfend! -- but I simply don't have the energy to putter around with it! I've got all the cool software, I've played around with the various slicers and splicers and modelers (oh, my!) and I find that I simply don't have the spoons to deal with the thing very often, much as I would like to. I'm not as good at modeling as I thought I was -- back in the old ray-tracing days I did okay -- but the current crop of tools (Great Ghu on a pogo stick, don't get me started on how much of a pain in the tuchis Blender is!) can be a kilometer the other side of too damn much. And just as soon as I start getting the hang of a tool, the company that makes it changes their (dingbatted, expurgated, censored) licensing for the program and suddenly I can't afford to use it. (I'm looking at YOU, Fusion 360!) So now I'm back to Tinkercad and trying to make sense out of AC3D to see if it'll serve (I think it will, last time I had the energy to look at it). I've got lots of ideas for stuff to make, and could even see myself making a 3d printer project for the key socket adapter box I made someday. It's a nice little box that consolidates the key sockets in one place, and the same kind of connectors, instead of one kind on the left side of my KX3 and another, totally-incompatible with anything but the Elecraft paddle on the bottom. I have 4 TRS sockets, two of which are set up for Paddle and run to a jumper cable into the left side key socket, and two of which connect to the bottom 2x2 header and are set for Hand Key. I used the paddle screws for the bottom connector to hold the box to the bottom of the radio, where it fits very neatly. If I want to plug in a straight key, I use one of the two right-hand sockets. If I want to connect a paddle, it goes into one of the sockets on the right. I get an extra socket for each type as well. Right now, I have my Torsion Bar Cootie Paddle plugged into it on the "Paddle" side, but if I want it to be a Cootie, I just move it to the jacks on the right -- they're pre-jumpered to serve for a Cootie, straight key, or bug. Very convenient! But I digress... The whole "cover up the ports so they don't get filled with schmutz" concept is a good one IF you take the radio where there be schmutz. My KX3 is on a RAM mount clamped to the wire "bread" rack next to my recliner, the PX3 right above it. I used SideFX mounts, so I can unclip the radio and/or Panadapter at any time...if I want to hurt myself, as that (more dingbats, expurgations, and censoriousness) polycarbonate stuff is STIFF, and my fingers aren't what they used to be. So the KX3 stays in the house and the cheaper and less-dear IQ32 or other kit built rigs go with me to the park. Or DID go with me to the park...we'll see if I'm able to do that any more once it warms up a bit more and stops raining every 43.5 minutes out of nowhere. The lockdowns really messed up my ability to get any meaningful exercise, and I find it hard to do a whole heck of a lot of walking these days. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Mon, May 10, 2021 at 1:53 PM Jim Brown wrote: > I don't understand the need to have a cover for an unused jack that's > not outside, exposed to the elements. > > 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 ardrhi at gmail.com > From kwroberson at yahoo.com Mon May 10 18:49:40 2021 From: kwroberson at yahoo.com (Ken Roberson) Date: Mon, 10 May 2021 22:49:40 +0000 (UTC) Subject: [Elecraft] UHF - W2 Sensor References: <1584996528.2689592.1620686980630.ref@mail.yahoo.com> Message-ID: <1584996528.2689592.1620686980630@mail.yahoo.com> Anyone have a W2 - DCV/U 200a_144-450 MHz UHF sensor for sale contact me.

The big issue is 49.380 MHz is an unusual frequency and probably a custom order frequency standard. The knockoff makers generally don't spend for a custom part. They take a standard TCXO and generate that frequency using a crappy PLL based synthesizer with high phase noise and lots of spurs. I have not tested this particular type (Elecraft replacement) though. Others I tested were awful. The result would be more interference between radios that are physically close to each other and on the same band. such as contest and Dxpedition stations. The low phase noise is a big reason that Elecrafts are prized for such applications. Both RX and TX are affected. I make replacement TCXOs for Kenwood TS-590s. They also use an unusual frequency but I was able to get a TCXO chip supplier to provide me a custom frequency chip that I had to buy in some quantity. That allowed me to produce a quality product, although things are upside down now with the component shortages in the industry. If huge companies like auto makers and a company with a decent volume like Elecraft have part procurement problems, you can imagine how bad it is for a really small fry like myself. Has Elecraft stated why they are no longer available? I have not checked with my supplier recently, but I expect there would be no interest in low volume runs when demand can't be met for their high volume parts. 73, Mark W7MLG On Mon, May 10, 2021 at 5:58 PM Hank via Elecraft wrote: > I was thinking the same thing.

Osc. Compatible In-Reply-To: References: Message-ID: They are no longer available from Elecraft based on an email I received several weeks ago when calling to ask for a replacement. I sent my K3s in for an upgrade and to be generally looked over last year. I had already installed the KTCXO-3 crystal new from Elecraft earlier but was still having frequency drift issues. The factory replaced that one with a new one and upon return it began to drift. Without an external reference connected - I have to change the ref frequency almost every time I use the radio. 2 meters is so bad on SSB that it is unusable. I have switched back to the original crystal that came with the rig new in 2018. It is much better and I can use my rig for outings like field day or training exercises without a reference signal. For the money spent on a new rig in 2018 (which was the single most expensive ham radio purchase I have ever made and the first and only new Desktop HF transceiver I have ever owned) I am not happy that I can?t even get simple parts for repair less than 3 years later. If I knew a new model was approaching I would have waited. The factory has given me 2 options: use the original crystal which I am doing and the performance is ok, or take my KTCXO-3 and tweak it with a screwdriver to get it back closer to the reference frequency. I have done the first because I can?t do the later. 2 meter SSB is still a little off with the old crystal. I feet certain that my KTCXO-3 is bad and no amount of tweaking will allow it to be stable so sending back to the factory again probably will do no good.

The big issue is 49.380 MHz is an unusual frequency and probably a custom order frequency standard. The knockoff makers generally don't spend for a custom part. They take a standard TCXO and generate that frequency using a crappy PLL based synthesizer with high phase noise and lots of spurs. I have not tested this particular type (Elecraft replacement) though. Others I tested were awful. The result would be more interference between radios that are physically close to each other and on the same band. such as contest and Dxpedition stations. The low phase noise is a big reason that Elecrafts are prized for such applications. Both RX and TX are affected. > > I make replacement TCXOs for Kenwood TS-590s. They also use an unusual frequency but I was able to get a TCXO chip supplier to provide me a custom frequency chip that I had to buy in some quantity. That allowed me to produce a quality product, although things are upside down now with the component shortages in the industry. If huge companies like auto makers and a company with a decent volume like Elecraft have part procurement problems, you can imagine how bad it is for a really small fry like myself. > > Has Elecraft stated why they are no longer available?

It passes all serial lines straight through from PC (normally) to Radio RS232, and taps the RXD line (Pin 2) for the KPA500, KAT500, SteppIR, etc. This works with POLL OFF as long as a logging program is polling the radio properly. It also works in series with the K3S + CBL3PY + P3. The S-BOX can just as easily be inserted as a null modem cable + tap between TS-890S and TS-590S (and as a Y-cable to the KPA500, with TS-890S Pin 2 connected to KPA500 XCVR SERIAL Pin 2). So, it should work to connect the serial connector of the TS-890S to the TS-590S with a tap, but as you say, if Kenwood only supports that master/slave connection at 115200 baud, as stated in the Kenwood manuals, then neither the KPA500 or KAT500 will be able to track, since they both max out at 38400. FYI, the KPA1500 XCVR SERIAL connector supports all common baud rates from 4800 to 230,400 baud, but the KPA500 does not. 73, Bob, N6TV https://bit.ly/S-BOX On Mon, May 10, 2021 at 12:24 PM Andy Durbin wrote: > "I have a TS-890S that has a KPA500 connected to the radio's serial > port.

Yes the manual says that the Main / Sub radios must be connected at 115,200 bps, and while it was some time ago, my testing here seemed to prove it true. The 890 does install 2 virtual com ports for the USB connection: standard and enhanced. The standard port is used for radio control and audio in and out. The enhanced port seems to have limited functionality. It's a little beyond my skills and abilities to figure out if the band data is available here and if so, how to get it to the KPA500. I've gotten away with a single receiver for decades, so no big deal, or I can just go with the RF sensing on the amp.

But, once you've completed it and made your first QSO where you proudly say "Rig here is an Elecraft K2 that I just finished building...", you have a sense of ownership unlike anything you just took out of a box and plugged in. It's a marvelous little transceiver. It's truly fantastic for cw but shines in SSB as well. I can't recommend the experience enough. I've learned to have a very ZEN mind when I built them. Total focus on exactly one thing - a resistor, capacitor... what ever it is... do it perfectly and don't think of anything else. And then admire its perfection when its done. When I finish a board, I inspect it with a quality magnifying glass. I look at every solder joint, every part placement like it's a work of art - which, in many ways, it is. Whether it becomes your main radio or sits on a shelf awaiting an occasional use - it is always a source of personal pride. To me, building something like the K2, is a very important part of the Ham Radio Experience. 73, Doug -- K0DXV On 5/10/2021 1:08 PM, David Haines wrote: > I wish you all would stop talking about how much fun it is to build a > K2!?

My KX-3 (S/N 62**) gets very little use, so it's time to let it get. The radio has only been used a few times outside for backyard or picnic table "dxpeditions." This is a fully loaded radio with all options (except for the 2-meter module), It includes: * KXFL3 - dual bandpass roofing filter * KXAT3 - automatic tuner * KXBC - charger (with realtime clock) for internal NIMH batteries * MH3 - hand mic * KX3-PCKT - accessory cable package * KXSER - radio-to-computer USB cable * Pro Audio Engineering KX31 heatsink * Nifty Mini-Manual for the KX3 * Fred Katy's book - "The Elecraft KX-Line." * The Elecraft KX3 Owners Manual I think 60% of the original price is fair for this pristine radio. $1200 plus Priority Mail shipping ($21.90) to any US ZIP Code. I will be happy to send pictures to anyone seriously interested in the purchase, if you can put up with my primitive photography skills.

We strongly recommend that all K4 owners perform the update to remain current and take advantage of the latest improvements. An Ethernet connection is required to obtain new software. The K4 accesses our software server directly. To perform the update: 1. Tap the Fn button (on the LCD), then hold UPDATE 2. Select "Production Release" from the pull-down menu at the top of the screen. Then tap the "Check for Updates" button. This will download (but not install) the latest files. Note: You can tap "Release Notes" to read the release notes before doing an "Install" (step 3), if desired. You can also read them after installation. 3. Tap the "Install" button. This will install all software and firmware that is newer than what you have at present. NOTE: When the load process has completed, if you see any error messages in the status area of the update screen, please try loading a second time. This is a one-time step that may be needed that takes advantage of improvements in the updater itself. For more detailed information, tap the "?" button on the LCD from within the update screen.

Copies of each are attached for your use, but will of course be stripped from this post before it is sent to the reflector. K3_Remove_Replace_DSP_Board_Rev_B.pdf replace p35 and p30 on the k3.doc When the Elecraft website was rearranged according to type of document (manual, modification, part installation), the manuals for part installation appear to have been removed from the website. As far as I can tell, this is the case both for the parts no longer available and also for those still available, like the front panel gold pins p35 and p30.

The remoterig boxes just act as an IP-protocol converter for CAT, audio, ptt, etc. So without IP in between you do not need them. Most connections like mic, ptt, key, speaker can be wired directly. For CAT most probably you have to connect at the RS232 level, so at the K3/0-mini side convert from USB to RS232 and use the RJ45 RS232 at the K3s side. (mind the grounding of pin 1 in the RJ45 connector, otherwise the CAT data stream is routed to the K3s USB port; see schematics) When you get CAT going the rest is straight forward. If this set-up will be free from hum, rf-pick-up, etc. is another matter, depending on the local situation. 73 Henk PA0C -----Oorspronkelijk bericht----- Van: elecraft-bounces at mailman.qth.net Namens Paul GACEK via Elecraft Verzonden: woensdag 12 mei 2021 03:27 Aan: Elecraft Reflector Onderwerp: [Elecraft] ?Direct connect? of a K3/0 to K3s feasible/possible? Is it possible to connect, using just copper wire a K3/0 to a K3s and forgoing a pair of Remote Rig devices? The use case is a K3s rack mounted in my house and a lot of cat6 (4x pair of copper) wire running around that is not connected to my LAN. The K3/0 would be in another room and I?d use a free cat6 to connect the /0 and the k3S. Scenario is CW. Given it?s last order time on K3 parts, I want to check feasibility of the K3/0 without spending a fortune on the remote rig boxes given my use case is intra house. Anyone have any ideas or direct experience?

One example is the KDVR3. Here is a link to the manual on the K3 website: https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740130%20KDVR3%20Option%20Installation%20Rev%20C.pdf In those instructions, look at pages 6 thru 8 on how to separate the front panel from the rest. In the process, you will also remove the bottom front cover which you need to have off to replace the p35 and p30 jumpers. 73 de Raj, N2RD > On May 12, 2021, at 12:47 PM, Paul Kirley wrote: > > Dear OM Pete N4ZR, > > Instructions for removing and replacing the K3 front panel assembly are included in the following two Elecraft documents, neither of which I was able to find today on the Elecraft website.

The average mail client, like Thunderbird can be set to send both HTML and plain text. Some clients, more specifically those that use webmail CAN send in HTML only.

Have you tried running the K3S directly into a dummy load to see if the ALC behavior is the same as what you've observed (or run the KPA500 in STBY mode to bypass its PA)? Just wondering if the issue arises in the KPA500 ALC feedback to the K3S rather than directly in the K3S itself?

Message-ID: <97E3B80F-DD88-4FCB-96FA-47AF258D8D1C@gmail.com> In a mild panic here. Need some wise advice. Set up my brand new KPA500 and KAT500 today with my K3. Used only Elecraft cables and followed the wiring configuration carefully. Set the K3 for bypass of the internal ATU. All the KPA menu items are set to factory default. When I power up the KPA the screen says INVALID. My limited understanding is that the KPA thinks it is being told to operate outside of its frequency range. But the K3 is set to 80m and well within the band edges. My thinking is we have a failure to communicate in that the K3 is not sending the frequency to the KPA, perhaps sending no info at all. Any thoughts? I?m assuming I have overlooked a simple setting on the K3 and/or the KPA.

This is either coming from the radio?s BCD pins or from RF sampled by the KPA500. First thing to make sure is that the pins in the AUX cable are contacting properly, and are not bent and thus not plugging in properly. Check this on both cables, all four connectors. Did you get this indication without transmitting any RF? If you did get it from an RF transmission, that would indicate that the sampled RF is outside the acceptable range of the KPA. This range is from 1.6 to 26 MHz and from 28 to 54 MHz. Let?s see what we can do to gt you going - I may ask for a fault log if your checks don?t fix things so I can see exactly where the band problem is being picked up. 73, Jack, W6FB Elecraft Engineering > On May 14, 2021, at 8:47 AM, Steve Fox wrote: > > In a mild panic here.

Well my KPA500 must be broken. It changes bands with the band buttons with neither serial port connected and no AUX data source and with K3 selected as radio. It also changes bands with any other radio type selected.

It depends on what is plugged into the AUXIO connector. If nothing, then the KPA will see the BAND signals all high and will assume that no K3 is connected. If a K3S is connected (or K3 with KIO3B), but off, then the same situation applies since the K3S will not pull the BAND signals to Vcc in this case. In this situation, it will then act the same as if RADIO is set to BCD and will change the band on its own in response to a band button press. If a K3 with the original KIO3 board is connected, then the KPA will behave exactly as I described. in this case the KIO3 is pulling the BAND signals to Vcc (0V) and thus indicating 60 meters (even though it is off). The KPA will then believe the radio is active and will try to send the band info to the radio, but will not see a band change. It will thus stay on 60 meters. So, it depends on the radio, but my original analysis is actually correct. 73! Jack, W6FB > On May 14, 2021, at 11:03 AM, Andy Durbin wrote: > > "If you try this, be sure to set RADIO = BCD.

Quick question for K3 owners. A local ham who has 2 K3 radios,wants me to take rig # 1 which has a newer KSYNA board,and swap it with radio # 2 which has the older board. I have done many upgrades where I remove the old board,replace it with a newer board..do the calibrate function as per the manual,and it works fine..super easy.. When I do it in reverse..put the older board back into a radio that has the newer board ..do I still do the calibrate step ? or will it work fine after the swap ?

That was the beginning of me being obsessed with perfection. Finally retired from a career starting with a 2H pencil, scale and triangles which matured to developing a 3-D design process on a brand new CAD system bought by my employer in the late seventies. The purpose of the 3-D process results was to be able to tumble large multimillion dollar structures to determine how they fit into the humankind environment.

The Brown Truck came at about 2 PM. That morning I had checked into an 80M net using my trusty K3. For 8)M is use an inverted V. All was well. Monday afternoon was a frenzy of setting up and using the new K4. Pretty easy setup. All week long I used the K4. All was good, but I was disappointed at signal strengths on 80M. I kept thinking that the K4 just couldn?t receive well on 80M! Yesterday I was out in the back doing yard work. That?s when I noticed that the support ropes on BOTH ends of the 80M inverted V had failed, and the the antenna was lying on the ground! We had had a storm come through here Monday mid-day, and my supposition is that the support ropes had failed. I restored the support ropes, and low and below the K4 works well on 80M again! I normally would have noticed the change in SWR, and realized that I had an antenna problem. But, of course, I had tuned the K4 for the first time on 80M when I received it! A learning moment (operator error?). Gonna try to check the antennas out a bit more frequently! 73, Tom W4KX From dbthompson at me.com Sun May 16 10:08:46 2021 From: dbthompson at me.com (David Thompson) Date: Sun, 16 May 2021 07:08:46 -0700 Subject: [Elecraft] K1 backlight kit In-Reply-To: <680235705.595675.1621170408987@mail.yahoo.com> References: <4153F235-4006-432C-AE43-10AC2E4ACB71@me.com> <680235705.595675.1621170408987@mail.yahoo.com> Message-ID: <0485B57C-F19E-4500-BC0B-AE445C591F47@me.com> > On May 16, 2021, at 06:06, Louandzip via Elecraft wrote: > > If you can't find a kit: I modded my K1 to illuminate the LCD back in '03, before the mod kit was available.

Morning Lou, I looked on the Elecraft site and the part number for the transreflective LCD is E600015. A search for that part number on the site turned up nothing. So they don?t appear to be stocking that part anymore. If someone reading the reflector knows the source for that part, I will see if I can find one. If not, I found this approach ? https://bit.ly/3fgvtL2 ? to adding a backlight to a built K1. With a little tinkering, the latter should work as well. Thanks Lou!

On the assumption that the K4 antenna tuner has similar capabilities to the one in the K3/K3S, it can tune anything. An antenna lying on the ground is child's play for these tuners. Tom said that he hooked up his spiffy new K4 and tuned the antenna. No wonder he didn't see a bad SWR. :-) 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)348-7900 | services.

This includes: - documentation and software updates - K4-related product announcements - issue alerts (operational or hardware) - technical topics of broad interest - Day-to-day discussion supporting K4 user questions will go only to the Elecraft-K4 list. I've resisted any sort of list bifurcation in the past, but I believe it's called for in this case.

Message-ID: <1621447332824-0.post@n2.nabble.com> I put SN122 through its initial paces today. Here are some of observations: Appearance and general behavior: 1. This is a very good looking radio. The front panel design looks great. 2. The rear panel has more room than the K3. 3. The BNC connectors protrude farther out the back panel than the K3, and look a little strange to me. (But who really cares what the back panel looks like!) 4. The touch screen is extremely easy to read in all lighting conditions that I've used so far (it's gorgeous!). 5. The touch response is very good, though every once in a while it seems to have to "think" a little before responding. Build quality: 1. The cabinet fit and finish are as good as I've seen. It's very solid and the finish is great. 2. The interior is very interesting. Most parts appear to be very cleanly integrated. The CPU has a bit of a "tacked on" appearance. I applaud Elecraft for not trying to design their own high performance processor board, but the interface cabling looks a little ad hoc. It all works, but I have to wonder how it would survive getting knocked around enroute to a Dxpediton. 3. The front headphone jack was completely dead on my radio, but the rear headphone jack was fine. It was pretty easy to figure out how to release the front panel (thanks to Wayne's excellent video on the 3D model of the K4). The front headphone jack attaches to its circuit board with a socket that plugs onto a 4-pin header. That connector was completely off the header. When I connected it, I noticed that the insertion force was almost nil, so it's likely that it came off during shipment. I slightly bent a couple of the header pins to provide a little more friction. When I got it back together it worked fine. I believe that it would be good to consider adding more physical restraint to that connection. 4. The pushbutton switches on the front panel are much more solid, with better tactile feedback than the K3. I like them much better. Operating impressions: 1. Rx audio seems to be less fatiguing than the K3. 2. Tx audio reports were very good (from trusted critical sources). 3. Tx audio compression seems to be very weak compared to the K3. Even at 30 (max setting), it seemed to do less than a setting of 10 on the K3. It might need some DSP attention. 4. Most of the UI is absolutely great. Things like setting EQ levels for Tx and Rx using a touch screen were a real dream-come-true. There are multiple ways to do many things, and there is a little bit of irregularity in the ways to do things. However, overall I think it is very easy to use given the complexity and huge variety of controls that are needed. 5. The spectrum display system is a work of art. I always found it necessary to have an external monitor on the P3 to make it really effective. In most cases, I feel that the spectrum display on the K4's built-in screen could stand alone. However, I'm hanging on to my external monitor because the ability to configure it independently of the built-in screen likely will open up many valuable use-cases for display management. 6. Data and CW decoders can run simultaneously on the A and B VFO frequencies. So this radio can actually copy two different QSOs at the same time. That's very cool. Also the CW decoder seems to work better than the K3's, though that's hard to quantify. One caveat - I believe using both decoders is effectively a "multi-channel decoder" as defined by some contest rules. You may want to check before enabling it during a contest to ensure it doesn't put you into the Assisted category if you don't want to be there. Station installation: 1. My goal was to disconnect my K3s/P3 pair, and then "drop in" the K4, making note of the changes that needed to be made. It turned out to be very easy to get it going in my station. Here's a quick summary of what I did: a. For CAT control, I moved the DE-9 from the P3 to the DE-9 on the K4, removing the daisy chain cable between the radio and the P3. b. The K-Pod changed from its original custom cable to a standard USB cable going to the back panel. c. The external monitor changed from a VGA connector on the P3 to an HDMI connector on the K4 (fortunately my monitor has an HDMI port). d. I added a (shielded) Ethernet connection. e. I removed the IF plumbing for the P3. Everything else was identical between the K3 and K4. That includes keying in and out, accessory connector going to KPA/KAT500, custom TX inhibit input, and Mortty FSK. Special shoutout to N6TV for the awesome Y-box! Since I used the RS-232 serial connection for control, I didn't have to change ANYTHING in N1MM to take control of the K4. It just worked! All I had to do was select the different sound card instantiation that appeared in windows to get data modes working. Actually, I also needed to select the correct inputs on the K4 for the different modes and set levels. But the transition from a fully integrated K3s/P3 to a fully integrated K4 was less than an hour, including full N1MM integration. There are so many different ways to integrate both the K3 and K4 that your mileage will almost certainly vary. 2. The K4 takes less room horizontally than the K3/P3 combo, but it is deeper (see attached photos). That actually helped me because the front panel ended up a little closer to me than the K3's did. I have a pretty deep desk, but if you have tight quarters in front of your K3, you may have to rearrange some things. One weird thing: 1. I noticed very shortly after I turned the radio on for the first time (AF gain at zero, no antenna connected) that I thought I had a ringing in my ears. When I turned off the radio it went away. It wasn't loud, it just felt like a very slight case of tinnitus. It was sort of like one of those high pitched tones that you try to guess if it's there during a hearing test. I noticed that it seemed to come and go as the display came up and went away. (I resisted the urge to hold my finger up and down as it came and went :) Then I noticed that it got fainter if I turned the display brightness down. Just to be sure I wasn't imagining it, I hooked a microphone up to my PC and Audacity, held it in front of the display, and then powered up the radio. I could see nothing in the time domain, but when I ran a spectrum on it, there was a very distinct spike at 10 kHz. The spike disappeared with the radio off. The "ham demographic" probably includes very few who could hear it, but I'm one of them. Just to put it in proper perspective, I'm that guy who during sound checks in church says "where is that squeal coming from?" and everyone else looks at me like I'm nuts. It's just barely on the edge of being annoying, but there is hopefully something that can be done to mitigate it for those of us that can still hear weak 10 kHz audio. My guess is that it is a DC-DC boost converter somewhere in the display with a ringing inductor. Bottom line: While very reminiscent of the K3, this is NOT a K3. It sounds better on Tx and Rx and its UI is a whole new animal for Elecraft (in a good way!). It has far more connectivity and control options than the K3, which means you will have to invest some time to learn how the K4 thinks and acts. I waited exactly 2 years (to the day!) for this radio, and I can say that it was certainly worth it for me. Congratulations to Wayne and the whole Elecraft team for getting this radio out under some really tough conditions. 73, be safe, have fun!

Here are some of observations: Thanks, Rick. My comments below. > 3. The BNC connectors protrude farther out the back panel than the K3, and look a little strange to me. (But who really cares what the back panel looks like!) Unlike the K3, the five BNC connectors on K4 have bushings that are used to physically and electrically secure the connectors to the rear panel. This is part of the overall noise-reduction strategy. It also provides very rigid mounting for the RF board. > 2. The interior is very interesting. Most parts appear to be very cleanly integrated. The CPU has a bit of a "tacked on" appearance. I applaud Elecraft for not trying to design their own high performance processor board, but the interface cabling looks a little ad hoc. It all works, but I have to wonder how it would survive getting knocked around enroute to a Dxpediton. Our goal here was to be able to adapt to future single-board-computer technology rather than be constrained to what's available today. Swapping boards would be a matter of adjusting mounting screw locations on the replaceable adapter bracket and at worst, replacing a couple of cables. > > 3. The front headphone jack was completely dead on my radio, but the rear headphone jack was fine. It was pretty easy to figure out how to release the front panel (thanks to Wayne's excellent video on the 3D model of the K4). The front headphone jack attaches to its circuit board with a socket that plugs onto a 4-pin header. That connector was completely off the header.... We're going to improve the mating connectors. Thanks for finding and reporting this. > > 4. The pushbutton switches on the front panel are much more solid, with better tactile feedback than the K3. I like them much better. This is due to our use of real tact switches beneath the rubber in the K4. The K3 (and our other products with rubber switch matrices) uses carbon-dot contacts that rely on hysteresis in the rubber itself. > 3. Tx audio compression seems to be very weak compared to the K3. Even at 30 (max setting), it seemed to do less than a setting of 10 on the K3. It might need some DSP attention. Agreed. This is on our list. > > 4. Most of the UI is absolutely great... > > 5.

I noticed very shortly after I turned the radio on for the first time (AF gain at zero, no antenna connected) that I thought I had a ringing in my ears. When I turned off the radio it went away. It wasn't loud, it just felt like a very slight case of tinnitus. It was sort of like one of those high pitched tones that you try to guess if it's there during a hearing test. I noticed that it seemed to come and go as the display came up and went away. (I resisted the urge to hold my finger up and down as it came and went :) Then I noticed that it got fainter if I turned the display brightness down. Just to be sure I wasn't imagining it, I hooked a microphone up to my PC and Audacity, held it in front of the display, and then powered up the radio. I could see nothing in the time domain, but when I ran a spectrum on it, there was a very distinct spike at 10 kHz. The spike disappeared with the radio off. The "ham demographic" probably includes very few who could hear it, but I'm one of them. Just to put it in proper perspective, I'm that guy who during sound checks in church says "where is that squeal coming from?" and everyone else looks at me like I'm nuts. It's just barely on the edge of being annoying, but there is hopefully something that can be done to mitigate it for those of us that can still hear weak 10 kHz audio. My guess is that it is a DC-DC boost converter somewhere in the display with a ringing inductor. We'll definitely investigate whether it's a DC-DC converter on the front panel board or within the LCD itself. If there's a way to suppress the 10 kHz a bit, we'll find it. > > Bottom line: > While very reminiscent of the K3, this is NOT a K3. It sounds better on Tx and Rx and its UI is a whole new animal for Elecraft (in a good way!). It has far more connectivity and control options than the K3, which means you will have to invest some time to learn how the K4 thinks and acts. I waited exactly 2 years (to the day!) for this radio, and I can say that it was certainly worth it for me. Congratulations to Wayne and the whole Elecraft team for getting this radio out under some really tough conditions.

Just watch the amplitude of the signal - when the beat goes to as close to zero as you desire, you are "there".? I have found that I can easily get as close as 1 beat in 5 seconds, which is 1/5 Hz or .2 Hz in the final calibration. There is a limit to the DAC steps that may keep you from getting to an absolute zero beat - this is not an analog thing, but then it is more stable than an analog VFO, so there is some tradeoff. 73, Don W3FPR On 5/19/2021 6:54 PM, Louandzip via Elecraft wrote: > I count beats.?

It is a very low stress part that sees at most 5 volts at very low current. R22 is different for each sensor - the values shown in the schematic are not necessarily correct. Also, these are precision 1% resistors. With that in mind, the values are: 2KW HF Sensor, R22 is a 2K ohm 1% SMT resistor. 200W HF Sensor, R22 is a 1KW 1% SMT resistor. 200W VHF Sensor, R22 is a 4.7K 1% SMT resistor. We need to be careful what we might plug the sensor cable into. The standard box would not stress the resistor to the degree that the resistor blew, especially since that connector also has a ground attached as well. If it were to be plugged into something like an ethernet adapter, I would expect the sensor not to survive since those pins connect to entirely different signals with different characteristics. 73, Jack, W6FB > On May 20, 2021, at 6:12 AM, William Carpenter wrote: > > My W2 wattmeter suddenly stopped working properly this morning along with > that dreaded smoke smell.

One needs to do a careful zero beat cal first, to make sure you are in the ballpark. You can verify later by tuning to 9,999,998 and counting the beats in 10 seconds. The number of beats on the two frequencies should add up to 40. Incidentally, by counting the number of beats in 10 seconds on 10,000,002 (or 9,999,998), you can estimate your residual frequency error in tenths of a Hz (beyond the capability of the dial display). For example, if there are 23 beats in ten seconds, your radio is telling you that you are 2.3 Hz from zero beat, so you are actually tuned to 10,000,002.3 Hz. That info can be used to correct your results in the Frequency Measuring Test (FMT), but is of no other practical use that I can think of. It was fun to beat some of the big boys in the last FMT, using only a stock K3 without even a TCXO!

Does the K3, like the TS-590, have a user option that defines how the change to CW is handled? The options are typically to keep the dial frequency the same and shift where the RX is listening, or to keep listening in the same place and shift the dial frequency. In either case the shift is the chosen CW pitch. 73, Andy, k3wyc From jstengrevics at comcast.net Thu May 20 18:02:23 2021 From: jstengrevics at comcast.net (John Stengrevics) Date: Thu, 20 May 2021 18:02:23 -0400 Subject: [Elecraft] Not Able to hear CW In-Reply-To: References: Message-ID: <2F9078A8-FCCF-4574-A5AD-96BE926670D8@comcast.net> Unfortunately not that simple Andy.

With it producing about a 1 kHz tone in the tx data mode, I switched the mode on my k3 to CW. the tone dropped down by 600 hz, which is the CW offset/sidetone point I have in my K3. If you hear it on the tx data mode, and you move to CW, adjust the vfo +/- 600-700 hz, and I'm sure you will hear it. The radio is just shifting the offset.

Not that I know of. In digital and SSB modes, the dial frequency is the suppressed carrier. In CW mode, it's the actual signal frequency. The K3 takes the desired CW note frequency into account. In RTTY modes, it's the Mark Frequency. When you switch to CW to hear a CW signal that you heard in Digital mode, you'll have to tune it in. The K3 has a front panel button that allows the op to use plus or minus CW offset. 73, Jim K9YC From hms4 at lehigh.edu Fri May 21 06:18:07 2021 From: hms4 at lehigh.edu (Howard Sherer) Date: Fri, 21 May 2021 06:18:07 -0400 Subject: [Elecraft] New PC not finding the KPA 1500 on its USB port Message-ID: I just purchased a new Dell laptop to be installed at my remote KPA 1500.

The ferns are unrolling, adding their hue to the mix.? The hemlock are adding new growth and some of the Doug fir are too. Time to add another antenna before the ferns get too thick. ? The sun is waking up.? Multiple CMEs have been shot out of AR2824.? In a day or two they should be aimed at us. SpaceWeather.com mentions we may notice unusual propagation below 20 MHz.?

I?m getting around 60K or 43K with my Fluke 117, depending on which way I connect the leads. Each of R10 and R11 individually test ok, and I don?t see any solder bridges or missing joints, and I?ve reflowed anything suspicious that might be related. Has anyone seen this or could offer an explanation before I start pulling parts or digging out the oscilloscope? The second check is also off. "Resistance between D3 anode (end without the band) and the ? ?? pad near D7 (ground) where the black wire is attached: > 100 K-ohms (may show open or infinite on some DMMs). Press S1 and confirm the reading drops to between 117 K-ohms and 130 K-ohms. If the resistance is higher, try reversing your DMM leads.? Attaching the red lead to D3 shows infinite resistance and pressing S1 reads 170K. Reversing shows about several M-ohm initially, but then pressing S1 gives 180K. Note that if I use normal automatic ranging it won?t get a lock on the second S1 measurement (with black lead on D3 and red on Ground), I had to use manual range.

I can add and subtract the ham bands and how they display when I use the Up/down buttons for the Band access. That works great. Is there a software switch somewhere that will add the shortwave bands into the list when I use the UP/down Band buttons? Such as being on 3.5, hitting up and going to 4.0 Mhz, then up to 5.0 Mhz, etc. Is there an easy way to access the bands or do I need to put them in the memories somewhere? Thanks.

I still think it's my multimeter in auto mode. I went back and retried the initial test using manual ranging and if I set the range to 600K it shows a reasonable value. I suspect the caps in the circuit are fooling it, will have to google that and see if there is an adjustment. The second test still shows a bit high as well, but if I measure from the *cathode* of D3 instead of the anode then I get a reasonable value as well; perhaps the difference in meter currents used for measurements is messing up due to the diode being in the circuit as the check is worded?

I can confirm the two switchover frequencies you mention (1700 and 3300kHz), but observe at most a couple of dB change when crossing the boundaries. I use an external panadapter (LP-PAN/NaP3 connected to IF-OUT) so I can easily see the same stations and noise while tuning across the boundaries. On the 1700kHz boundary the signals are a couple, maybe 3dB stronger when below 1700kHz. So it sounds to me that the filters in your KBPF3A are not being switched in when it is supposed to be used. The KBPF3 needs to be enabled (set to "nor") in the configuration menu. Have you checked that? Hmm, I neglected to carefully read the last part of your post. It sounds like your KBPF3A might be working above 4210kHz so may be just the 2 lowest bands are defective. If you look at the schematic you see that those two bands use the same filter but with some components switched in and out by another relay (K2). So that could narrow the problem down to one relay (K1) not operating. Is this a *new* problem or has it been like this since you got the K3 or installed the KBPF3A?

Not finding much activity here, Antenna to small forEME. Amateur satellites are moving objects, so you would need to know when a satellite?s footprint is over Shawnee. The ability to aim your antenna both in elevation and azimuth would also be helpful to provide the strongest signal to your receiver. You can look up a particular satellite?s expected passes over your grid square by using the ?Predict? page on the AMSAT website: https://www.amsat.org/track/index.php You can also review the list of active satellites and their downlink/uplink frequencies here: https://www.amsat.org/fm-satellite-frequency-summary/ Otherwise, is there another ham in the area that can fire up a CW/SSB/FM signal between 432-436 MHz (the coverage of the XV432)? Perhaps a member of a local radio club could assist.

Further info - Utah does not have a "by right" statute such as other states have, specifying a height at or below which the jurisdiction cannot restrict height. It does have a PRB-1 type statute that requires local administrations to grant "reasonable accommodation" by "least restrictive means" - which are legal terms that can vary amongst jurisdictions. I am a great fan of getting those limits adopted, which involvs hard work with legislatures. I don't know what your local zoning codes specify, but in those cases where I have written or reviewed local zoning codes, I have tried to get ham radio antennas exempted from Conditional Use Permits or Special Variances by a process called Administrative Permits that don't involve neighborhood hearings, notifications and fees, especially if there's a "by right" statute. Something that you need to check into. If you are required to get a Conditional Use Permit or to apply for a Variance and you need legal assistance - check out Kenneth D. Lougee, K7AAO in Sandy, who like myself is an ARRL Volunteer Counsel but is licensed in Utah. He is listed in the ARRL website for Volunteer Counsels. A building permit is a different kettle of fish. Cross that bridge after the :Land Use permit business is settled.

All other functions appear to be working normally, but the rotary encoder is disabled. If I ground the V- pin (via 100 ohm resistor) the encoder comes to life and functions normally. I have verified good continuity between encoder V- and pin 14 of U3. In the manual it says that the MCU can disable the encoder under certain operating conditions. What might those conditions be? One thought I have is that the MCU is disabling it for some reason. My current plan is to try replacing U3. All other functions of U3 appear to be working. Any troubleshooting advice would be appreciated.

It is possible for it to have one bad input and is quite static sensitive. But first, check that 8R and 8T signal lines are working properly.? An easy place to check is at the anodes of RF Board D6 and D7. The anode of D6 should be near 8 volts during receive and the anode of D7 should be close to zero. That situation will reverse during transmit. If you find 8R and 8T are on at the same time, that could be reason for the problem. If you have a problem with those signal lines, check back on the control board at Q1, Q2, Q3 and Q4 to determine where the problem might be. 73, Don W3FPR On 5/27/2021 4:15 PM, Josh Gibbs wrote: > My K2 (SN: 4073) suffered a sudden problem yesterday.

Try to set the fixed range a bit above the highest expected resistance for the best results. It all depends on the voltage the DMM applies to the circuit. Too high a voltage can make ICs and transistors conduct causing a low reading. 73, From rmcgraw at benlomand.net Thu May 27 21:51:26 2021 From: rmcgraw at benlomand.net (Bob McGraw) Date: Thu, 27 May 2021 20:51:26 -0500 Subject: [Elecraft] OT Need copy of "Antenna Zoning and the Radio, Amateur " second edition Message-ID: Be sure and check you local and state codes.

A K4HD would provide somewhat higher dynamic range for those stations in extreme signal environments, but the vast majority of operators will find that the K4/K4D more than meets their needs. I'd like to highlight a few important items in Rob's chart. First, the K4D has a high 2 and 20 kHz dynamic range value of 101 dB. Because it's a direct-sampling radio, this figure will hold at nearly all offsets from strong signals. Second is the block dynamic range number (128 dB), higher than almost every other "pure" SDR measured. Finally, there's the LO noise (local oscillator; 148 to 155 dB) -- again, very favorable compared to all competing SDRs. This is an important number correlated with reciprocal mixing dynamic range (RMDR). Taken together these demonstrate that the K4D will offer excellent performance in crowded band conditions. Inevitably a question will arise regarding the chart position of the K4D relative to a couple of our other transceivers: the K3S and KX3. There's a bit of "apples to oranges" in both comparisons. The K3S uses a superhet receiver architecture. The K4HD will provide a receive setting that emulates this superhet performance when and if it's needed. But the "pure" (direct sampling) method used by the K4 (all models) has many advantages. One is the elimination of artifacts associated with crystal filters. Another is that, as a pure SDR, the K4 has a far more flexible architecture. We'll be able to provide updates to the receive and transmit digital signal chains that cannot be added to a superhet like the K3S or its competitors. The KX3 is another Elecraft radio high on Sherwood's chart. Its performance is excellent, especially at its price point. But its numbers relative to the K4 are somewhat misleading, as hinted at by Rob's footnotes. The KX3 uses a quadrature downsampling architecture, which digitally samples at baseband audio rather than at RF. This is ideal for a radio like the KX3 that has to have very low current drain for portable operations. The K4 uses a direct-samping architecture that requires a higher power digital signal chain, resulting in important benefits over quadrature downsampling including much higher and more consistent opposite sideband image suppression and 2nd-order intermod rejection. So the two are really designed for different applications. Overall, this first independent test of the K4 validates the performance of our SDR architecture. Feel free to send us any further performance questions. 73, Wayne N6KR From n6kr at elecraft.com Fri May 28 13:04:51 2021 From: n6kr at elecraft.com (Wayne Burdick) Date: Fri, 28 May 2021 10:04:51 -0700 Subject: [Elecraft] =?utf-8?b?SzQg4oCcT3duZXLigJlzIE1hbnVhbOKAnS4=?= In-Reply-To: <5E604D1E-E94A-4679-A0BC-A3D3A7FF53D1@gmail.com> References: <5E604D1E-E94A-4679-A0BC-A3D3A7FF53D1@gmail.com> Message-ID: Hi Sid, We do plan to merge the printed "Introduction to the K4" manual with the "Operating" manual when time permits.

Most obvious among them: the K4?s quantum leap in user interface. Second is perhaps the expansion of digital audio interfaces, including HDMI video, multiple USB ports, and ethernet. The K4 also has unlimited expansion capability, both in software and hardware, to adapt to future needs. The HDR and transverter modules are only two examples. The ADCs and DAC are also located on small, easily upgraded modules, ready for whatever exotic technologies the future may bring. The internal main CPU is also in an industry standard form-factor so it can be easily upgraded.

This is especially useful with external amplifiers. Mine is set to PER-BAND. If a KPA500 is connected to the K3S via the ACC cable (as mine is), two sets of per-band power settings are saved: one for ?barefoot? operation, one for use with the amp. Where and how do I save and then access these two savings? Are the somehow automatically selected? In my case I want to save 100 watts for "barefoot" operation and 25 watts for amplifier operation. I've tried using Quick Memories 1-9 for bands ? which works fine ? and Quick Memories M1 and M2 for the two power settings for each band ? which does NOT work. What's the right way to do this?

We made it much easier than that. Make sure you have the K3 and KPA connected with the AuxIO cable. Now go to a band on the K3 (matched on the KPA500). With the KPA in STBY, set the power setting on your K3 to whatever you want - probably 100 watts. Next tap the OP/STBY button on the KPA to put it in OPER mode. Then adjust the power setting on the KPA to the lower value for the KPA (25 watts is what you indicated). After this when you switch the KPA in and out of OPER mode, the K3 will show you the change on the ?B? display and it will automatically set the K3 power for what you want. I usually set my OPER power while transmitting so that I get what I want out of the KPA. I have two KPAs & K3s, and each needs a different TX level to drive the KPA to full power. Hope this helps! 73, Jack, W6FB > On May 28, 2021, at 1:34 PM, Richard wrote: > > In the Config Menu: > > PWR SET > If set to PER-BAND, the power level is saved on each band. > This is especially useful with external amplifiers. > > Mine is set to PER-BAND. > > If a KPA500 is connected to the K3S via the ACC cable (as mine is), > two sets of per-band power settings are saved: one > for ?barefoot? operation, one for use with the amp. > > Where and how do I save and then access these two savings?

Using my K3 and KPA 1500 on Six meters FT8 I get this message only while transmitting on the K3 screen with no indication of a problem on the KPA 1500 . If I place the KPA 1500 into standby mode the message does not appear. I do not use ALC. There seems to be no reference to this error message in either manual. The amplifier seems to be working just fine. If I lower the K3 drive (8W) drive to the amplifier so that the K3 KPA internal amp is not engaged but the KPA 1500 is in operate mode, the problem does not occur. Should I increase the power to 12 W from the K3 with KPA 1500 in operate mode the error code does appear. Again the KPA 1500 seems to operate perfectly. The K3 at 95W with KPA 1500 in STBY does not result in the KPA 1 message. What does ERR KPA 1 indicate on the K3 screen? Thank you for your help. 73 Doug EI2CN SWR 1.1 to 1 -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Richard Sent: Friday 28 May 2021 20:35 To: elecraft at mailman.qth.net Subject: [Elecraft] K3s Power Selection In the Config Menu: PWR SET If set to PER-BAND, the power level is saved on each band.

Because it's a direct-sampling radio, this figure will hold at nearly all offsets from strong signals.

Finally, there's the LO noise (local oscillator; 148 to 155 dB) -- again, very favorable compared to all competing SDRs.

The K4HD will provide a receive setting that emulates this superhet performance when and if it's needed. But the "pure" (direct sampling) method used by the K4 (all models) has many advantages. One is the elimination of artifacts associated with crystal filters. Another is that, as a pure SDR, the K4 has a far more flexible architecture.

The KX3 uses a quadrature downsampling architecture, which digitally samples at baseband audio rather than at RF. This is ideal for a radio like the KX3 that has to have very low current drain for portable operations. The K4 uses a direct-samping architecture that requires a higher power digital signal chain, resulting in important benefits over quadrature downsampling including much higher and more consistent opposite sideband image suppression and 2nd-order intermod rejection. So the two are really designed for different applications. > > Overall, this first independent test of the K4 validates the performance of our SDR architecture.

Relative to the current production release (13), the beta update includes many new features and improvements. Here are a few highlights: MACRO EDITOR -- Allows operator to customize up to 13 switch functions on the K4 itself as well as all 16 functions of the K-Pod remote controller. Supports virtually the full K4 remote-control command set. RECEIVER PERFORMANCE -- Changes have been made to significantly improve dynamic range under extreme signal conditions. (Sherwood's receiver performance table reflects these changes.) SSB/ESSB BANDWIDTH CONTROLS -- You can now directly set the SSB and ESSB transmit bandwidth. ADC OVERFLOW INDICATION: The "+" symbol in "+60" on the S-meter turns magenta if the associated receiver's ADC hits overflow level. In previous releases this was happening on some transitions from RX to TX. With this corrected, uers can now set MENU:RX Auto Attenuation to ON if desired. * * * Full release notes can be viewed at the K4 at the time the beta release is downloaded (and prior to installation, if desired). Let me know if you have any questions about the new beta code. Additional minor changes will be made for the next production release. 73, Wayne N6KR From msadams60 at gmail.com Sat May 29 20:56:44 2021 From: msadams60 at gmail.com (k2qo) Date: Sat, 29 May 2021 17:56:44 -0700 (MST) Subject: [Elecraft] KPA500 cabinet buzz In-Reply-To: References: <1917A1F1-C862-41E0-ACFF-C7CCBFC088D1@mac.com> <003401d3964f$e31281a0$a93784e0$@ad6a.com> Message-ID: <1622336204380-0.post@n2.nabble.com> After much searching, this 2.4 year old thread is the only info I can find on this issue.

I own two. KPA Numero Uno was bought way back when, when the kits were first available. When I first built it, it buzzed something akin to to your teeth clacking when you notice a full-grown T. Rex is standing next to you. At that time, many were complaining about KPA500 buzz, but one must understand that some would complain that their K3 did not come with the case stuffed with Krugerands. A call to Support convinced them it was really loud. They sent me an updated bolt, washer, and spacer set. I very carefully repositioned the transformer, and torqued the bolt to factory spec. Several times. No buzz then, no buzz now that I can hear. I do now have an LP-100A sitting on the top left forward of the cabinet. A perfect fit. Perhaps that is a dampner, who knows. KPA500 Numero Two-o was bought this year, is factory-built, and has a very slight audible buzz on cw. These amps have compact, toroidal, linear transformers that produce a little buzz. If it ever rises to an annoying level, I would: 1) Turn off the amp using the front-panel switch to drain the filter caps and let the fan run all the way down. 2) Turn off the rear-panel switch. 3) Unlug the amp from A/C. 4. Remove the top cover as shown in the manual. 5) Using a very strong light, see if the transformer is touching the cabinet. 6) If so, you can SLIGHTLY. loosen the bolt (PAY ATTENTION TO THE TIGHTNESS OF THE BOLT IF YOU DO NOT HAVE A TORQUE WRENCH), and very, very carefully adjust the transformer so it is a hair away from the cabinet on all sides. 7) Reverse the steps. Repeat if necessary. OR Call Support. OR wear headphones. OR Fuggedaboutit. NOTE: You can indeed make it worse. The reason you are probably hearing it for the first time is that all amps I have owned with linear supplies also buzz, but the constant fan masks it. 73 Eric WD6DBM On Sat, May 29, 2021, 5:57 PM k2qo wrote: > After much searching, this 2.4 year old thread is the only info I can find > on > this issue.

Message-ID: Hi, A report on recent events with my KX3: When I tried to use it yesterday, I found that several buttons were no longer responding: PRE, ATT, MSG and CLR. Tried power-off/on, no change. Removed the battaries for 5 minutes, no change. I was able to go to setup and started SW TEST so I could test the front panel. Every button and knob was working, except for these four, which didn't show up with the test. Looking at the K3 schematics, these buttons all share the same SCAN103 going to pin27 of U10 on the front panel, the front panel processor. Briefly, there is a voltage divider (R81, R80, R90, R89, R96) and operating any of the four buttons should switch a different voltage to SCAN103. This clearly worked for SCAN100, SCAN101, SCAN102, SCAN104 but not for SCAN103. I was worried that the SCAN103 input was zapped. Looking for people wo encountered this before, I found the blog from OK1RP (http://ok1rp.blogspot.com/2019/05/no-response-from-msg-pre-and-attn-keys.html). On the blog, the solution was to disconnect the flexfoil PCB between control board and RF board, clean the contacts and re-install. I checked the connectors - they were seated correctly as predicted in the blog, I disconnected them, looked for dirty / corroded connectors, and re-set it, and fortunately the issue was solved. So, if others encounter this, Petr's blog may help. But, I still wonder what had happened. The SCAN103 signal is not connected to said connector and a bad contact cannot affect SCAN103. SCAN103 only connects said buttons and the CPU, and that is all on the control panel - no-where near to the interconnect connectors with the flexfoil. I wonder if an initialisation issue on the frontpanel processor U10 can have caused this? Looking closer at the schematic, I see that the SCAN lines are completely floating if a button isn't pressed. If nu button is pressed, the input represents a high-impedance floating input. A static field (an operator walking to the radi, and, without touching the radio first, opererating one of the buttons) may perhaps cause an issue setting up the input. I wonder why these pins don't have 100k to GND or so? Perhaps the disconnect made power really disappear to do the recovery? I noticed that my KXBC3 clock was running 20 minutes behind after the operation - that is the time I worked on the issue, so just removing the power isn't good enough to really drop all power. I don't want to badmouth Elecraft, and I don't want to start a war similar to the "yaesu IF filter discussion" of a few years back, but I wonder if someone has done a more thorough investigation? I note that adding resistors is easy (add them at the encoders) and wonder if this is a change that has been implemented with newer KX3 builds?

The K3, like most exciters, does pull down the KEY PTT line just before transmitting RF; we just keep that from reaching the amp. This technique works with a lot of exciters, without a need to modify them to emit RF without pulling down the KEY line. Our KPA1500 ATU tune button interrupts the amp key line, (putting the PA in standby temporarily) and can be configured to send a message to K3 or K4 to start tune level RF. When ATU tune is complete, the amp sends a message to the exciter to cease sending RF, and after RF level drops, the amp restores the key line interrupt relay. 73 de Dick, K6KR > On May 30, 2021, at 07:32, James Beitchman wrote: > > ?I think the answer is no, but I'll ask this question anyway. > > > > The station configuration is K3 followed by amp followed by automatic > antenna coupler, where the Key Out line of the K3 is used to switch the amp > inline. > > > > I would like to generate RF from the K3 without switching the amp inline in > order to operate the automatic antenna coupler at low power from the K3 > before putting the amp inline.

K4 owners are encouraged to give the examples a try, allowing them to gradually become more familiar with the transceiver's capabilities -- including some they may have missed. * * * K4 Highlights #1: Stereo Audio Pitch Mapping Working in CQ WPX this weekend, I was reminded of the "wall of sound" effect you can experience during a CW contest. This was the motivation behind the K4's AFX PITCH feature (pitch-mapping audio effect). While AFX PITCH can be used in other modes, it really shines in CW mode, especially when wider bandwidths are used (800 Hz and up). What it does is "map" lower-pitched signals to the left, and higher-pitched signals to the right. All it takes is a little DSP magic. Here's one way to think of it: Imagine you're listening to a great jazz ensemble using mono headphones. Yes, you can hear all the instruments, but your brain does a lot of extra work in separating them. Now put yourself near center stage in an actual performance venue: the performers surround you, with each instrument's voice standing out distinctly thanks to binaural hearing. This is what happens when you turn K4 pitch mapping on. The effect with headphones on is dramatic. Steps: 1. Tap MAIN RX. 2. If the AFX button shows AFX OFF, tap to turn it ON. 3. Hold the AFX button to switch from DELAY to PITCH. Headphones and wide CW bandwidths are recommend when you first try this. This will give you the full effect. And you'll want a pileup or contest to be going on to provide plenty of signals. Full disclosure: The CW operators in your passband won't know they're part of your own private band. And unless it's a traffic net, they won't be working together on a single composition. Yet whatever notes they're playing, they won't sound like they're all sitting in the same chair. 73, Wayne N6KR From a.durbin at msn.com Sun May 30 12:30:47 2021 From: a.durbin at msn.com (Andy Durbin) Date: Sun, 30 May 2021 16:30:47 +0000 Subject: [Elecraft] KPA500 cabinet buzz Message-ID: "The KPA-500 transformer should be more than just a "hair" away from sides (step 6 above) as there are rubber bumpers and a ribbon cable between that should NOT be pinched.

In case you could just switch a remote relay which yes/no passes the PA PTT signal you are all set. You could use the switch capacity of the Remoterig boxes and activate a relay remotely. Remoterig provides a web-based switch (see manual) You could also use one of the Remoterig COMM ports. This circumvents the need for a PC, just a switch can be used. I do use COMM1 CTS as (control) input and have at the radio COMM1 RTS as output. At the control side I have added a MAX232 so I can use a switch to ground at the MAX232 input. (output to COMM1 CTS) At the radio side RTS goes to a simple transistor relay driver. You can use the remote relay for anything you want, so also PA PTT control. In case you need more specifics just send me a mail off list. 73 Henk PA0C -----Oorspronkelijk bericht----- Van: elecraft-bounces at mailman.qth.net Namens James Beitchman Verzonden: zondag 30 mei 2021 18:35 Aan: 'Dick Dievendorff' CC: Elecraft at mailman.qth.net Onderwerp: Re: [Elecraft] Can the K3 make power without activating Key Out?

I wonder if the DIGOUT1 output of the ACC connector can be made to do what you want: drive a relay that interrupts the KEYOUT line. Alternative (and perhaps more expensive): The KPOD has 3 outputs that can be switched using serial commands. If you try this, be aware that the documentation of the KPOD is (or was) wrong: tip is output3, not output1, and vice versa. If you want to use this to drive a relay you probably want a PNP transistor as buffer. 73, Geert Jan PE1HZG From jackbrindle at me.com Sun May 30 16:33:13 2021 From: jackbrindle at me.com (Jack Brindle) Date: Sun, 30 May 2021 13:33:13 -0700 Subject: [Elecraft] Can the K3 make power without activating Key Out?

The ATU should have a signal that indicates when it needs to do a tune (or is doing one). Simply use that signal to operate a relay. That relay either passes the Keyout signal to the PA (normal), or opens the relay to unkey the PA (tuning). That is exactly what the KAT500 does with the KPA, or any other PA it operates with. This is a very simple, and elegant automatic solution. 73, Jack, W6FB > On May 30, 2021, at 9:34 AM, James Beitchman wrote: > > Thanks, Dick, > > But here is the real issue, not reported in my post. > > My antenna - my only antenna - is a non-resonant 600 foot square loop which provides amazing performance especially on high bands.

Message-ID: "So I guess the correct sequence would be to press TUNE on the KAT500 and then push TUNE on the K3 and the KPA500 would not KEY. Correct? Why not have pushing TUNE on the KAT500 initiate the whole sequence...unkey the KPA, start the TUNE on the K3 and tune?" That's may not be as perfect a solution as you might think. While I developing my Kenwood/KAT500/KPA500 controller I found that KAT500 enabled the key line when its internal logic saw the tune sequence had terminated. That was before TX had completed and there was a large power spike. KAT500 should not re-enable the key line until it detects RF has gone to zero. (Maybe it works better with full Aux bus integration with a K3). For me the solution was simply to manage the entire tuning sequence with my controller. One key press and the rest is automatic. The sequence is: Detect tune request Ensure KAT500 keyline is inhibited Initiate tune TX and increase tune power to level needed by KAT500 Initiate KAT autotune Detect end of autotune Terminate tune TX and reset tune power to low level Verify TX has terminated Enable keyline (but only if KPA500 OPER mode is active) It may sound complicated but the effort of developing the code is more than paid for by having a completely automatic single button capability. As a bonus I save the tuning solution that existed before tune initiation so it can be restored if I don't like the new solution. 73, Andy, k3wyc
