Assuming you have a MAHA/Powerex MH-C9000, for charge I would use 200 mA or 500 mA, if you have the time, and 1 A otherwise, and sparingly 2A if it's going to make your life better with operating time. In general in seems lower charge rates generate less heat and that's good, but 1A isn't really a problem. The MH-C9000 sets charge with current, and then decides when it is done. It will show you the charge delivered to each cell. The internal charger is low rate and time only. That seems fine too. I also recommend doing a "refresh-analyze" cycle, 200 or 500 mA charge, 200 mA discharge, and recording the results (and putting labels on each cell) when you get them, and every year or so. I have found that batteries that aren't tested can't be relied on long term. 73 de n1dam From anthony.scandurra at gmail.com Sat Oct 1 09:05:35 2016 From: anthony.scandurra at gmail.com (Anthony Scandurra) Date: Sat, 1 Oct 2016 09:05:35 -0400 Subject: [Elecraft] [K3] FW 5.5 issue??

I'm referring to the buttons 1, 2, 5, and 10 above the frequency in the VFO B panel of Commander. They do still turn on split in the radio and offset the VFO B frequency correctly. I thought they were also supposed to turn on my subreceiver and check the Dual receive box in the VFO A panel.

I don't have. My question was really: is it desirable to always aim for the lowest inductance of an ATU tuning. AFAIK this question is totally independent from the wire length.

I understand that either my english is very weird. Or that I can't explain things good. But that you and Davidthink that they must make a 42 joke on this is definitely weird. The question was: I can query the KX3 ATU for what it settled. I have an end fed antenna and so I have various variables: - used tap (1:4, 1:9, 1:16) - some random length wire - band And forget an "optimal wire", I might just have switched from 12m to 10m. Or back. Depends on what I find, propagation ... so assume that my wire is just some random wire, not necessary optimal for the band. And also, in the context of my question, this is entirely irrelavant. I was never asking about wire lengths, this is easy to read up. Okay, back to my scenario: I just switched the new band. I'm not going to let my portable glass fiber down because of that and change the wire length! Instead I do what a lazy OM does: I press the TUNE button and the internal magical antenna tuner does it's job. It's actually so magic, that it will do it's job on all taps. On the 1:4 tap, on the 1:9 tap. And on the 1:16 tap. Woah! But I can query the ATU for what inductance and capacitance it used to do the match. And so my simple question was: would a lower inductance have less losses inside the ATU? And please: if you don't know the answer of if you think that there is no answer, than just stay silent. 73, Holger From heinz.baertschi at bluewin.ch Sat Oct 1 11:25:43 2016 From: heinz.baertschi at bluewin.ch (Heinz Baertschi) Date: Sat, 1 Oct 2016 08:25:43 -0700 (MST) Subject: [Elecraft] how to optimize end-fed?

Message-ID: <7179DDC0-658F-4D50-9A26-33C0788ED831@mac.com> To the K3/P3 utility experts? A friend of mine, owner of K3/P3, has not updated his K3/P3 firmware, nor utility programs, in at least 3 years, possibly 4 years. The loss of his antenna, a divorce, and a move from one state to another lead to his long downtime. Now, he is anxious to get back on the air and fire up the old K3/P3. He asked me for instructions, I told him the following: 1. Get the latest versions of the utility programs for the K3 and P3 first. 2. Only need to update the latest set of software/firmware files since they are inclusive of all previous changes. Now, I am pretty sure I am correct on item 2 but not 100 percent confident. Given that he may have not updated for the last 4 years, is there anything special he made need to do. I don?t think he is interested in joining this group even though I have suggested it a number of times. 73, phil, K7PEH From jim at n7us.net Sat Oct 1 11:52:17 2016 From: jim at n7us.net (Jim McDonald) Date: Sat, 1 Oct 2016 15:52:17 +0000 (UTC) Subject: [Elecraft] [K3] FW 5.5 issue??

The higher the mismatch, the higher the feedline loss. Let's say you're operating on 14.300 MHz, and your wire is roughly 9.85 meters (32' 4") long. If I did the math right, that's pretty much exactly 1/2 wave, and the impedance at the feedpoint (the end) is near infinity. Your 16:1 tap might be good enough to bring that into the ATU range. The SWR would likely be high. Make the wire a bit longer (to get away from the exact 1/2 wave) and the impedance comes down. At some point, you'll get a better match (lower SWR) on the 4:1 tap than the 16:1 tap. For some wire lengths, the 1:1 tap will give the lowest SWR between the tuner and the wire. I'll be honest and say that I don't know how the inductance in the tuner is related to SWR. If you trim the wire so that the impedance is 800 ohms (16 times 50) and use the 16:1 tap, the SWR between the UNUN and the Tuner should be 1:1, but we're no longer talking about "random" wires. I'm sure those who invoked The Hitchhiker's Guide to the Galaxy were trying to point out that, without getting into a lot of specifics, it's hard to answer. That's why I picked 14.300 MHz -- to make the question far more exact. Humor doesn't always translate, however. Stay on 14.300 and make the wire three times longer, and the discussion stays the same -- instead of the wire being 1/2 wave long, it's 1 1/2 waves. Move to 7.150 and double the length of the wire, and the discussion stays the same, only the lengths change. This page talks about "random" wires, and the lengths that do fall near an odd multiple of 1/2 wave. Staying away from these lengths makes the tuner's job easier. I'm also ignoring (on purpose) how well the antenna radiates. It seems to me that if the power doesn't get into the antenna, it doesn't much matter. I'm sure we'll now hear suggestions from those who think another type of antenna is better, but your original question is the same with a miscut dipole as it is with a high-impedance end-fed wire. 73 -- Lynn On 10/1/2016 7:26 AM, Holger Schurig wrote: > My question was really: is it desirable to always aim for the lowest > inductance of an ATU tuning.

Should have gotten up earlier. To add to Lynn's comments, setting the balun tap to the lowest SWR means you are minimizing the work that the tuner has to do and as a result probably minimizing it's losses, as well. So to summarize... 1. Bypass the tuner and select the balun tap that gives you the lowest SWR. 2. Activate the tuner and enjoy lots of QSOs.

The Cout capacitance should be set to the highest value possible with the L and Cin supporting that for lowest SWR. I think this means the higher the inductor's Q the less losses seen in the matching network. Does this mean the higher the inductance (higher inductive reactance) the higher Q and the lower loss? That's how it is looking to me. I don't know what kind of matching network is used in the Elecraft ATU.

Use 80 meters instead of 40. When you come to the first point where the RF Voltage is substatially less than the Expected value, that is the output of the problem stage. You can then examine the schematic to see the components associated with that stage and evaluate each individually. 73, Don W3FPR On 10/1/2016 2:00 PM, Philippe wrote: > On Thu, Sep 29, 2016 at 07:12:58PM -0400, Don Wilhelm wrote: > I need to go 'deeper'.

The system is the final amplifier, the ATU, the feedline, the UNUN and the antenna. If minimizing the loss in the ATU increases the loss elsewhere, then we aren't optimizing the whole system, probably the opposite. From the subject, it's "how to optimize end-fed?" and without any other constraints. On 2 meters, I've used a lot of J antennas, and found them to be pretty awesome performers. It's an end-fed half-wave, with a quarter wave matching section. Build one out of wire for an HF band, and the same antenna is called a Zep. Properly trimmed, you don't need a tuner, but they're single-band. 73 -- Lynn On 10/1/2016 10:03 AM, Logan Zintsmaster wrote: > To add to Lynn's comments, setting the balun tap to the lowest SWR means you > are minimizing the work that the > tuner has to do and as a result probably minimizing it's losses, as well.

Anything your internal KX3 ATU can match it will match with good efficiency. Allow me a couple of observations that might help. Your assumption about low L is correct since, in any well made matching network, the greatest losses are when high circulating RF currents flow in inductors and result in resistance losses in the wire. In many modern miniature inductors using toroids, those currents can actually cause strong enough magnetic fields to "saturate" the torodial core, causing it to heat and consume more power. In the extreme, the core may crack. And heating the toroid may cause it to reach its Curie temperature where its magnetic properties change dramatically, which changes the inductance of the toroid. In operation, that may appear a a sudden large change in the SWR after transmitting for long enough to heat the core. "L-networks" such as Elecraft uses are very high efficiency matching networks. Other popular networks you will find used by Hams, such as the "T" network, may have wider matching capabilities but can produce very high losses as well. All passive elements, such as a coil, have some losses. So I avoid any extra elements that aren't necessary. If you are feeding your antenna wire directly - it is connected directly to the KX3 I'd not use an external coil unless the KX3 cannot find a decent match (by decent I mean 2:1 or lower). If you have a transmission line between the KX3 and the antenna you need to consider the losses in the transmission line, especially if it is a low-impedance line such as 50-ohm coaxial. If the transmission line is not terminated at the antenna in its characteristic impedance (e.g. 50 ohms for common coax) there will be standing waves on the transmission line. Those standing waves will produce areas of high currents flowing in the transmission line and result in losses due to resistance in the wires. In that case you can reduce the total losses by matching the transmission line to the antenna impedance at the antenna. The KX3 may be able to match the antenna, including the transmission line, to the KX3 but that won't reduce losses in a mis-matched transmission line. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Holger Schurig Sent: Saturday, October 1, 2016 7:39 AM To: Fred Jensen Cc: Subject: Re: [Elecraft] how to optimize end-fed? 2016-09-30 21:59 GMT+02:00 Fred Jensen : > This is reminiscent of one of the five volumes in Douglas Adams' > trilogy, "The Hitchhikers Guide to the Galaxy."

In that ? a logging program (Log4OM) when shutting down would drop the audio on the K3 and K3S to nil. A slight touch of the shift or width knob or the XFIL key would restore the audio. I had posted about this issue on this reflector a while back with no replies. Reverting back to FW 5.33 or 5.38 would seem to resolve the issue. FW 5.50 and up seemed to introduce the problem. I tested with two different computers and reloaded the logging s/w, replaced cables and more all to no avail. Granted a logging program shutting down audio on a rig is small potatoes among many of the issues I read and learn about here and everyone?s operations, but it still was a valid problem. I?m glad it appears that the Beta 5.54 has possible cured my (and a number of others) hiccup.

I don't think you can simply combine the two outputs. Any phase differences in the signals coming out of the two receivers will result in added canceling and/or adding of the signals. I can see two ways to go: 1. Two sound cards and some software that either understands the diversity. Or some software that will feed your existing software the stronger signal. 2. Some hardware that measures the signal strength on the two outputs and swaps which one is then fed to the computer depending on the signal level. Software that would take both signals would give the most options for extracting the last dB out of the signals. But an external "strength selector" would probably be a pretty simple project for people with soldering skills! Good luck, - Brendon KK6AYI.

The K3 and K3s only output a single audio stream (main Rx or sub Rx when properly set up, but not both). So what Don say is correct for the stock radio with sub-Rx, but... Full diversity receive is possible (using dual receive sw: Linrad or MAP65). But you have to add more equipment to enable this. I did that for dual-Rx on 2m-eme by adding a breakout of the 1st IF for the sub-Rx and connecting the 1st IF of both the main and sub Rx to two LP-Pan units (working as SDR) who I slaved to one LO so the two signals would be phase-locked and the two IQ baseband audio would stay in phase. Those four lines go to a two channel stereo soundcard (M-audio Delta44) which produces the two IQ data streams to a computer for each receiver in the K3. But you have to have a SDR sw which accepts dual-RX input to obtain a diversity result. At present only Linrad or MAP65 do that. WSPR is not included as option under MAP65 and I do not think Linrad can support it, either (less certain about Linrad). So there is a diversity solution to provide two signal streams but no dual receive vers of WSPR. I wonder if one might be able to run two essense WSPR on one computer with each taking input from a receiver? You still would have to manually compare WSPR output from each to determine which has the better signal. A good computer geek might be able to write an interface to both WSPR to compare each and outputting the best result. Here is how I set up my dual-Rx 2m-eme adaptive receiving system. With it I receive 2m in both Vertical polarity and Horizontal polarity with MAP65 providing the best signal reception (plus providing the actual signal polarity angle): http://www.kl7uw.com/LINRAD.htm So not exactly correct that diversity reception of digital modes is not possible; it is for JT65 with the addition of the necessary equipment. 73, Ed - KL7UW --------------------------------- From: Don Wilhelm To: MaverickNH , elecraft at mailman.qth.net Subject: Re: [Elecraft] WSPR & Diversity RX Message-ID: <0d1cfa26-19bb-a09b-93dd-e6bf695ffd82 at embarqmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed Bret, Since the computer soundcard is working only with one channel, diversity mode will not help - unless you can create an 'add-on' to interpret both channels and decide which one has better reception. When using Diversity Mode, you listen with both ears to the left and right channels and your brain figures out which is the better side to listen to - one channel from the main RX and the other from the subRX. With digital modes, the soundcard is listening only to the left channel - main RX. Yes, you have antennas that will do diversity for you, but that will only be useful in voice modes and CW because the human brain will automatically decipher the best signal from the two channels - you listen to diversity with one channel in each ear. 73, Don W3FPR On 9/30/2016 5:36 PM, MaverickNH wrote: > I'm wondering about my K3S in Diversity RX on Digital modes, such as WSPR.

Hmm, take each audio stream from the stero headphone. You would need two soundcards or a four channel card like the Delta44 because you need two data streams to produce diversity reception. So that does not solve the issue that WSPR does not provide for dual channel input. You might try running two instances of WSPR's on a computer to handle each diversity channel but that still leaves you with two displays which you would have to manually inspect for best signal. MAP65 does this for two JT65 inputs but does not support WSPR. Solution is for someone to write a dual-Rx version of WSPR for diversity reception.

Set the K2 to 4000kHz and measure the left end of R30 - it should not be above 7.5 volts (nearer to 6 volts is better). Then tune to 3500kHz and again measure the left end of R30 - it should not be below 1.5 volts. If it is within that range, the VCO is properly locking. If it is not within that range, do the VCO Alignment as indicated in the manual on page 64 (if the manual is older, you will find it on page 55). 73, Don W3FPR On 10/1/2016 2:00 PM, Philippe wrote: > On Thu, Sep 29, 2016 at 07:12:58PM -0400, Don Wilhelm wrote: >> Phil, >> >> Don't be too quick to draw that conclusion. >> Note that everything in the Low Pass Filter will appear to be connected to >> ground at DC.

If you simply combine two audio streams there can be phase cancellation, noise on one channel ruining both, and other issues. In contrast it's simply marvelous what our brains can do when left ear is listening to main RX and right ear is listening to sub RX locked to main RX frequency and RF/AF gains and AGC are set to create a "sound stage". Signals come from a point on the sound stage and noise is spread around. Signals in a pileup can spread around the stage. And since it has the normal "spatial spread" that we hear in normal life it's easier to listen to, less tiring. These are significant advantages that only apply in part to digital mode where the specific and nasty programming has actually been done. Check your third party digital decoding program's user's manual but don't hold your breath. Would be great if someone actually took that on. 73, Guy K2AV On Saturday, October 1, 2016, MaverickNH wrote: > Hi Don, I thought that might be the case.

Look at the release notes for both the production and beta firmware to see if there is anything that interests you - if so, download it. There are several on this reflector who are not familiar with the difference between Elecraft production firmware and beta firmware, and many are reluctant to install beta firmware. IMHO, beta firmware is just as good as production level, but has not had as much testing by customers who bring to the plate the variety of configurations possible - different loggers and control applications working in concert with the radio and remote control applications that pose additional potential for unforeseen problems to crop up. Releasing beta versions to customers allows that firmware to be tested under a variety of conditions that are not possible by a select few early testers. There is no fixed time between a beta release and when it is promoted to production level at Elecraft. If there is a flurry of customer requests for a new function, it can be a matter of days, but if there is not a high demand for the new or improved functions, it can be weeks. If you want the new function or problem fix, download and install the beta version. If you want a function that is included in the beta version, go ahead and download it, unzip and install it in your K3 (or K3S, KX3, KX2). If you encounter a problem, report it and revert to the production level or whatever level you have saved on your computer. Yes, it is just that easy. As far as firmware levels go, the revision level will remain the same if the beta version is promoted to production level - in other words, if revision 5.54 is determined to be adequate for production, it will still be revision 5.54. This production/beta revision there is a perfect example of the revision numbering. The production level is 5.50, but the current beta is 5.54. What happened to 5.51, 5.52 and 5.53? Those versions were released as beta, but either there was a problem reported by some of the early users, or it was further modified to add some additional function. Since the current beta is 5.54, it will be the one advanced to production level unless it is succeeded by a higher beta revision. Revisions 5.51, 5.52 and 5.53 will not ever be production level. In other words, if 5.54 needs to be "fixed", the fixed version will be higher than 5.54. There should be no fears about beta firmware "breaking your radio" because it has been initially tested in-house and by Firmware Field Testers.

Hi Don, A quick question for you: Lets say I am on 5.5, and I do a save via the K3 Utility software. ?I then update to 5.54. ?OK I am on 5.54, and my last save of the radio was while under 5.5. Now lets say I hate 5.54, and I want to revert. ?Can I just tell the K3 Utility to revert back to the previous save, or do I have to re-point the updating software at a version of 5.5, then load the firmware? I guess this boils down to-- is the K3 radio snapshot software, a full reversion, or is it just configuration settings reversion? Hope that makes sense... -- 73's, and thanks, Dave (NK7Z) For software/hardware reviews see: http://www.nk7z.net From dmoes at nexicom.net Sun Oct 2 20:11:41 2016 From: dmoes at nexicom.net (dmoes at nexicom.net) Date: Sun, 02 Oct 2016 20:11:41 -0400 Subject: [Elecraft] Notes on beta firmware In-Reply-To: References: <57f117b8.5077.8685b940.61e9b301@nexicom.net> Message-ID: <20161003001141.6738005.99264.35635@nexicom.net> Im sort of a don't fix what ain't broke. ? ?From time to time I look at the updates to see if there is anything jucy or effect?s my operation and only do the updates then ? why update firmware if it offers nothing to my personal operations.? ?One thing about this Beta update is the Fixed level on TX monitor to the line out. ? ? ?One thing I didn't ?like is that the line out was tied to the front panel monitor level and when recording messages or recording QSOs.

Look at the release notes for both the production and beta firmware to see if there is anything that interests you - if so, download it. There are several on this reflector who are not familiar with the difference between Elecraft production firmware and beta firmware, and many are reluctant to install beta firmware. IMHO, beta firmware is just as good as production level, but has not had as much testing by customers who bring to the plate the variety of configurations possible - different loggers and control applications working in concert with the radio and remote control applications that pose additional potential for unforeseen problems to crop up. Releasing beta versions to customers allows that firmware to be tested under a variety of conditions that are not possible by a select few early testers. There is no fixed time between a beta release and when it is promoted to production level at Elecraft. If there is a flurry of customer requests for a new function, it can be a matter of days, but if there is not a high demand for the new or improved functions, it can be weeks. If you want the new function or problem fix, download and install the beta version. If you want a function that is included in the beta version, go ahead and download it, unzip and install it in your K3 (or K3S, KX3, KX2). If you encounter a problem, report it and revert to the production level or whatever level you have saved on your computer. Yes, it is just that easy. As far as firmware levels go, the revision level will remain the same if the beta version is promoted to production level - in other words, if revision 5.54 is determined to be adequate for production, it will still be revision 5.54. This production/beta revision there is a perfect example of the revision numbering. The production level is 5.50, but the current beta is 5.54. What happened to 5.51, 5.52 and 5.53? Those versions were released as beta, but either there was a problem reported by some of the early users, or it was further modified to add some additional function. Since the current beta is 5.54, it will be the one advanced to production level unless it is succeeded by a higher beta revision. Revisions 5.51, 5.52 and 5.53 will not ever be production level. In other words, if 5.54 needs to be "fixed", the fixed version will be higher than 5.54. There should be no fears about beta firmware "breaking your radio" because it has been initially tested in-house and by Firmware Field Testers. I am surprised that the TX monitor out of LINE OUT was not discovered between MCU 5.40 and 5.50. My only conclusion is that those who used that function did not upgrade and observe the absence. An additional comment - use the firmware release notes to update your list of menu functions in the manual - for instance, MCU 5.40 added an option to the menu list for PA TEMP. 73, Don W3FPR On 10/2/2016 10:20 AM, dmoes at nexicom.net wrote: > > That explains it.

In the current situation of 5.50 vs. 5.54, if you do not have 5.50 on your computer, clicking Check Versions Fron Elecraft (or something like that) in K3 Utility should download 5.50 since the norm is to download the production version. If you have a prior version loaded in your computer, you can load that into the K3, it is just a matter of pointing K3 Utility to the prior firmware. So the answer depends on how many firmware revisions are resident on your computer. If you want to downgrade several levels, you may have to put the files in a separate folder and point K3 Utility to that folder. 73, Don W3FPR On 10/2/2016 6:55 PM, Dave Cole wrote: > On Sun, 2016-10-02 at 18:32 -0400, Don Wilhelm wrote: >> David and all, >> There are several on this reflector who are not familiar with the >> difference between Elecraft production firmware and beta firmware, and >> many are reluctant to install beta firmware. > Hi Don, > > A quick question for you: > > Lets say I am on 5.5, and I do a save via the K3 Utility software.

I have no idea how much programming is involved to do as you request, but I suspect a new menu entry to control the line out level independent of the monitor level front panel control would mean an added menu item. 73, Don W3FPR On 10/2/2016 8:11 PM, dmoes at nexicom.net wrote: > Im sort of a don't fix what ain't broke.

Unless you have added an IF buffer amplifier and IF output to your SubRX, you will not see signals from the subRX on your P3. 73, Don W3FPR On 10/3/2016 10:55 AM, John E Bastin wrote: > On Oct 3, 2016, at 10:19, Don Wilhelm wrote: >> John, >> >> The most common cause of that problem is the SubRX antenna selection - that is a per band setting. >> >> Go to 40 meters and get into BSET - then tap the RX ANT button. >> >> If that does not restore proper operation, contact Elecraft support. > I?ll check that, but it seems that if there was no antenna, there would be no signals in the sub rx on 40 meters, and I?m seeing the signals on the P3, I just have no audio. > > From w7ox at socal.rr.com Mon Oct 3 11:16:58 2016 From: w7ox at socal.rr.com (Phil Wheeler) Date: Mon, 3 Oct 2016 08:16:58 -0700 Subject: [Elecraft] K2 Utility In-Reply-To: <427b406f-7da1-2853-e8ab-eb55becafe5b@embarqmail.com> References: <1475504785254-7623052.post@n2.nabble.com> <427b406f-7da1-2853-e8ab-eb55becafe5b@embarqmail.com> Message-ID: <5a1402b1-0087-d9a0-b06a-0f1762f8e236@socal.rr.com> John, If you have a newly built K2 all firmware should be the latest. If you have an older one, purchased used, you may or may not need to upgrade the firmware by obtaining the ICs from Elecraft. To make that determination you must disassemble the K2 so you can see the firmware ICs and note the version written on them. Then look at the Elecraft site as Don says below and see if your chips are the latest -- and what any needed updates will do for you. The K2 was designed in the late 1990s. It and other early Elecraft transceivers (e.g. K1, KX1) did not have the capability to update firmware via downloads but required replacing the firmware integrated circuits. 73, Phil W7OX On 10/3/16 7:52 AM, Don Wilhelm wrote: > John, > > There is no K2 Utility. > To update the firmware in the K2, you must buy > the firmware ICs.

Message-ID: <54e9dd67-8722-195d-226a-901bfc208153@4email.net> Hola, Set up my K-Pod for K3 this morning. Initially a daunting task as I am not a programmer but between the Programmer's ref manual(my eyes glazed over after 6 pages), KE7X K3/P3 cookbook (Ch.11) and the enclosed instructions, was able to set up for my modest needs. What threw me off initially was the macro launch from F1-F8 as "Hold" rather than "tap". That struck me as counter intuitive as the K3's frequently used front panel selections are initiated with a 'tap'. The workaround was to select the appropriate macro from the K3 utility so as to mirror N1MM keyboard choices, such as F4 (tap) sends my call, by using Macro 12, which triggers M1 (HP1XT) on the K3. So, question is: Is it possible to reverse this selection so that F1-8 Macro from K3 Utility is a 'tap' rather than 'hold'? Ref page 6 of K-Pod instructions. 73 Tom HP1XT From wa2eio at optonline.net Mon Oct 3 14:41:13 2016 From: wa2eio at optonline.net (Ron Manfredi) Date: Mon, 3 Oct 2016 14:41:13 -0400 Subject: [Elecraft] New to the K3; ssb/cw question In-Reply-To: <2c703feb-7cc7-d34a-b2f8-7de6ce9afe78@embarqmail.com> References: <93634C54-0B55-48E9-8726-4D42A6116964@sssnet.com> <619df069-048b-a77e-8f9d-78e2ea3d50c6@embarqmail.com> <2c703feb-7cc7-d34a-b2f8-7de6ce9afe78@embarqmail.com> Message-ID: <0609eef0-16f8-24a5-8fbf-520a6e6af3cd@optonline.net> I have been getting acclimated to my (new to me) K3 and marveling over its many ways to customize its operation.

Will it ever be?, who knows. With the K-Pod, I believe a hold is easier to do because of the downward movement rather than a button on a vertical panel, and I believe that is the reason for the choice. Just move the macro into the proper slot for what you want. It is easy with the K3 Utility Macro Editor - you should be able to copy (or cut) from one and paste it into another. 73, Don W3FPR On 10/3/2016 2:37 PM, cx7tt at 4email.net wrote: > Hola, > > Set up my K-Pod for K3 this morning.

You should have the KXPACBL for best integration with the KX3. See pages 14 and 15 of the KXPA100 manual. If you do have those cables and have them connected correctly, then I would say that you have a problem with the KXPA100 and that you should contact Elecraft support. 73, Don W3FPR On 10/3/2016 5:53 PM, Gary Slagel via Elecraft wrote: > I'd like to be able to use my kx3/kxpa100 along with my k3 for so2r.

Some settings, such as AGC and equalizer, can take awhile to get what you want, their effects can be very subtle. Fortunately, the factory defaults right out of the box will provide you with a highly usable radio.

The amp will autodetect the new speed for the KX3 and you will not have to change anything else. On Mon, 2016-10-03 at 23:15 +0000, Gary Slagel via Elecraft wrote: > Thanks Don....

I used to save two frequencies in a memory...like 20m QRP and I would put CW in VFO A and SSB in VFOB. For some reason, when I load a memory now, it does not update VFO B. When I read the memories from the K3 using the memory management software, it shows the correct VFO B frequency and mode. However, if I save a new memory on the K3 and read it with the software, VFO B is set to the same settings as VFO B. Did this functionality quietly get stripped to scavenge more memory for other functions?

I have always been taught that they need to be biased down to about half their safe output to avoid thermal runaway. That was a long time ago. Things may have changed. As they heat up, they increase their amplification, as they amplify, they heat up, and so on. Cold temps works the opposite. In the early days of solid state mobile rigs, and during Minnesota winters, we could turn on our rigs and get nothing but maybe a back-light on the dial. After a few minutes, it would start to have sound coming out of the speaker, as the circuit and components warmed up. It also affects the oscillators.

My dad chuckled as I hefted my box of gear into the camper. At the time I had no battery powered radios. The receiver was a Heathkit HR-10B. The transmitter was a 3-tube, 10-watt, WW2 CW monstrosity I borrowed from someone in the El Cajon ARC. I also didn't have an antenna tuner, so I brought a full-size 40-m dipole with #18 wire and 100' of RG58. Keyer was a Heath HD-10. Our campsite in Utah didn't have an electrical outlet. Fortunately I had a very long extension cord that I routed through the window of the men's room, two campsites down. I had to apologize to hostile strangers as I wove the cord through bushes and around cars.

Unfortunately the band wasn't particularly open that day, and I think I ended up making three contacts. Still, I got The Bug.

I got a callsign (HB9XVK if I remember right) and took along an all-homebrew CW station. The receiver was a transistorized direct conversion type and the transmitter was an "AC-DC" type: it ran directly off 120VAC with no transformer. The tube filaments were wired in series (I think the lineup was two 50C5s and a 12AU7 or something like that) and the high voltage was rectified directly from the AC line. Of course I had to use an autotransformer to make it work with European 240VAC. Then the hotel put me in a basement room where the window looked out onto a patio, so I wasn't able to put up a decent antenna. I think I only made two or three contacts.

It will probably be an amusing break from the day-to-day to make an antenna. For smaller gauge loops, thin-wall flexible copper tubing is nice. The kind of stuff you hook up a fridge ice maker with.

Needless to say, I didn't set up camp too far away from the car! But it was rather nice to have a battery-powered all-solid-state rig without needing a step-up switching supply for a tube radio. A few years later I homebrewed a transceiver with camping as a primary goal, see here. This was a major step forward in convenience with a high fun factor. Now I usually just carry along the KX2 in a small pack. The antenna varies, but most often I use a 20 meter inverted V suspended from a cord tossed up into a tree. 73, Dave ----- Dave My Web Site -- View this message in context: http://elecraft.365791.n2.nabble.com/Camping-radio-ops-then-and-now-tp7623097p7623108.html Sent from the Elecraft mailing list archive at Nabble.com.

The MIC29150 regulator data sheet claims it works with all capacitors, though I haven't tried it. If the MIC29150 is used, the LC network is replaced with a short. The way I wired the regulator to the KX1 required cutting a trace on the PWB, so the power could be switched ahead of the regulator. This prevents the regulator from discharging the battery when the KX1 is off. If you prefer not to cut the trace, you could wire the batteries to the regulator input through a connector, and just unplug that connector when you're not using the KX1. The tuner is based on the Pacific Antenna BLT+, using most of the same parts. I bought the BLT+ kit without the case, replaced the transformer, and put it in my own box. The kit includes the N7VE SWR bridge. Note that my version is only intended to match end fed half wave multiples, with impedances from about 1,000 to 6,000 Ohms, and it's strictly QRP. 73, Scott K9MA On 10/4/2016 13:04, John Ellsworth wrote: > Scott - I also have KX1.

As part of the effort to squelch the awful ignition noise, I decided I would put ordinary coax braid around all of the plug wires and ground it to the engine block and the frame. About a month in I had a chance to meet a prospective client ? the senior VP of a California bank -- and drive him to a meeting of his trade association. He found the HW-101 hitting his legs somewhere between amusing and annoying. And then the car stopped. In the center lane of the Hollywood Freeway where, if I remember it right, it narrows and goes through Cahuenga pass. We alone were keeping 300,000 other drivers from getting home to the Valley in time for dinner. The prospective client sat in the car with his feet hitting the HW-101 as I tore all the braid off the plug wires trying to restore the shorted distributor. He was no longer amused. He was, from a business point of view, fatally annoyed. A KX2 if available at the time could have effected a career-altering change.

My dad chuckled as I hefted my box of gear into the camper. At the time I had no battery powered radios. The receiver was a Heathkit HR-10B. The transmitter was a 3-tube, 10-watt, WW2 CW monstrosity I borrowed from someone in the El Cajon ARC. I also didn't have an antenna tuner, so I brought a full-size 40-m dipole with #18 wire and 100' of RG58. Keyer was a Heath HD-10. Our campsite in Utah didn't have an electrical outlet. Fortunately I had a very long extension cord that I routed through the window of the men's room, two campsites down. I had to apologize to hostile strangers as I wove the cord through bushes and around cars. Getting the heavy dipole up into the ponderosas required rope, rocks, and a few swear words I hadn't used in front of my parents prior to that time. Finally, I was on the air. Unfortunately the band wasn't particularly open that day, and I think I ended up making three contacts. Still, I got The Bug. These days, I use a KX2, two lengths of #26 wire, an earbud/mic, and a KXPD2 paddle. Total station weight: 2 lbs, counting the CS40 bag. Setup time: 2 or 3 minutes, depending on how many times it takes to hit just the right branch with a 1 ounce stainless steel weight. Or 1 minute if I'm using a whip. It's been a wild journey that I suppose could be graphed in terms of miles per watt per pound over 40 years. I bet there a few other variations on this theme.... 73, Wayne N6KR From ron at cobi.biz Tue Oct 4 20:00:00 2016 From: ron at cobi.biz (Ron D'Eau Claire) Date: Tue, 4 Oct 2016 17:00:00 -0700 Subject: [Elecraft] Camping radio ops: then and now In-Reply-To: <4388601D-067D-44AA-987D-C32536104310@elecraft.com> References: <4388601D-067D-44AA-987D-C32536104310@elecraft.com> Message-ID: <005b01d21e9b$6ad083e0$40718ba0$@biz> My first was in the summer of 1954 in the Mojave Desert near a place called "Giant Rock", actually an Air Force emergency landing strip where Flying Saucer enthusiasts gathered for meetings, calling it the "Giant Rock Interplanetary Airport" although I never say any extra-terrestrial visitors. My buddy John (also a Ham) borrowed his family's Willis station wagon and built up a motor generator set with a small gas engine driving two 115 VAC, 400 Hz surplus aircraft generators. We had a national receiver and a Babcock and Wilcox CW/AM transmitter running a single 2E26 in the final so, I suspect about 30 watts d.c. input. No trees in the desert, so we had two 30 foot masts made out of pipe and lots of guy wires. It was more of an adventure setting up and getting on the air than actually making contacts, but a fun 3 days in the desert. We slept on the ground and perhaps the most memorable part of it was waking up one morning, crawling out of my sleeping bag and when I went to roll it up I discovered that a rattlesnake had crawled in with me to keep warm during the cold night. Fortunately he was still pretty cold and lethargic and so it was easy to extract him and send him on his way after a few minutes in the morning sun.

I was going out to a remote checkpoint on the Alaska Iditarod Trail (sled dog race to Nome) and my radio stuff did not make the load from one bush town to another so the box with radio sat outside in the snow overnight. When we arrived at the checkpoint which consisted of a wall tent at the edge of a frozen lake, I checked the big round temperature dial put up on a post (it read from -60 to +100F) and the needle say on minimum (-60F). It stayed there for three days so we had no idea how cold it got at night. Snow was three feet deep requiring one to wear snowshoes everywhere. The interior of the tent was warmed by a wood stove (55-gal oil drum converted to stove) to -15F. When I got my station first set up the LCD screen did not work (too cold) so I left it turned off to warm up a little. It worked fine then at -15F inside temp for the rest of the time. The Honda 800w lunch box generator would not budge when the starting rope was pulled...until we sat the generator on top of the stove for an hour to warm up the lubricating oil enough to turn over the engine. Ran fine once warmed and I did not stop it except for a few hours at night while we slept (wore my insulated underwear inside the down sleeping bag with my down parka draped over (like a cocoon). Third day it warmed up to +15F and we were walking around outside in our tee shirts it was "so hot". A day later arriving back in Anchorage where it was +30F the sweat poured off me just wearing my wool shirt and jeans outside. March-1986. I am installing my KX3 in my truck so curious if it will have any issues when cold. Its easy to disconnect and bring into a warm house or trailer so maybe will not have to face that. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From jdfreed at bellsouth.net Tue Oct 4 23:18:20 2016 From: jdfreed at bellsouth.net (John Freed) Date: Tue, 4 Oct 2016 22:18:20 -0500 Subject: [Elecraft] RF noise on 80M with KPA500 plugged into AC outlet Message-ID: <6672071ABC6646D9841B8BB34DDF0DC8@homePC> Here is an interesting situation.

Do you mean there's just a power cord plugged into the outlet, and the other end connected to nothing? If that's the case, I'd suspect arcing at the plug at one end of the cord, in which case you should replace that cord immediately, before it starts a fire. The only other possibility I can think of is that the wiring to the wall socket is in conduit, so it's shielded, and the line cord is acting as an antenna, radiating whatever junk is on the wiring.

Minus 60 degrees F. is the coldest on record for Minnesota, and you experience far colder that that. The cold may do multiple things to the K3 if it has multi-layer circuit boards. I didn't notice if it does. Our club left a repeater in an unheated enclosure one winter. I would estimate it wasn't much colder than minus 30 degrees F. at that location. (To clarify for others, this is 30 degrees F. below zero.) I have seen what the multi-layer circuit board looked like. More specifically, the thru-the-hole solder connections from one layer to another were cracked. Maybe it was the type of solder used??? I'm sure circuit designs have changed since the first solid state rigs I described in the cold. LCD screens hadn't been heard of yet. I'm surprised they don't freeze and get damaged in your temps.

Next cut an another arch from plywood of about 19" or 19 1/2" and nail it to the other arch forming a channel. Use the channel as a bending guide to slowly bring the tube into shape.

John KK9A From: K9MA k9ma at sdellington.us Wed Oct 5 00:20:43 EDT 2016 The only other possibility I can think of is that the wiring to the wall socket is in conduit, so it's shielded, and the line cord is acting as an antenna, radiating whatever junk is on the wiring.

If not, that may be the cause. Even if it is not the cause of that behavior, it is a safety issue for you and your family and is a requirement according to the National Electrical Code. The only exception is if the ground rods are more than 100 feet apart. A power cord - connected only to the wall receptacle should not cause any noise. Try the same with another power cord - if the same thing happens, examine your house wiring. OTOH, if the other power cord does not produce the noise, you may conclude that the original power cord has some sort of leakage problem. 73, Don W3FPR On 10/4/2016 11:18 PM, John Freed wrote: > Here is an interesting situation.

The issue is not with CWskimmer. I have successfully installed the program from current files on the DXAtlas Website. I also have a good copy of the sdr14x.dll that is supplied by the manufacturer of my SDR-I/Q receiver. However when I try to register the sdr14x.dll, Windows 10 complains that it 'may not be compatible'. When I run CWskimmer, it issues the error 'Unable to create SDR14X object' meaning it cannot find/use the active-x file to connect with the SDR-I/Q receiver. The sdrIQx.dll is an active-x component that is listed with the other .dll files in the System32 folder (C:\Windows\System32). If you are running CWskimmer using the SDR-I/Q receiver, you might have installed the sdrIQx.dll file I am looking for.

Turns out the RF Space provided SDR14X.dll worked fine once I was able to get Windows 10 to register it. Problem solved by moving the file to the C:\window\system32\sysWOW64\ folder where the 64-bit version wants the 32-bit dll files to reside. Then running command prompt as an administrator, I executed the 'regsvr32 sdr14x.dll' command and it finally worked. I had to use the regsvr32.exe program that is in the sysWOW64 subfolder, rather than the one in the System32 folder. CW Skimmer ran hooked up to my SDR-I/Q receiver happily immediately thereafter.

It's just a matter of principal, Phil. I've never in almost 49 years a ham purchased HF gear that did not, at minimum, include the schematics. I'm a retired electrical engineer for whom knowing a little about what's inside the box is actually **much more important** than knowing how to operate the box. I accept that firmware will always be shrouded and proprietary. For the hardware, if the complete (though not wholly current) KX3 system schematics can released, it is hard to understand why the same hasn't happened for the simpler KX2 system. Mine is unpopular philosophy today, when ham gear is becoming more and more like smartphones whose internal workings are shielded from the view of the vulgar mob. (For my phones, I get as much info as I can from the FCC OET Device Listings ... even for Bluetooth headsets!) I just did not expect Elecraft to adopt that attitude. :-) 73, Mike / KK5F From kl7uw at acsalaska.net Thu Oct 6 00:42:37 2016 From: kl7uw at acsalaska.net (Edward R Cole) Date: Wed, 05 Oct 2016 20:42:37 -0800 Subject: [Elecraft] Cold K3 Message-ID: <201610060442.u964gdQB022667@mail42c28.carrierzone.com> Dick, The KX3 will not see those extreme cold temps. Where we live it rarely drops below -15F and typically is 0 to +10F at night in winter. The KX3 has a RAM bracket in my truck so it might sit outside at night. I was wondering how it would react to being powered on at down to -15F. Truthfully it might not ever face that as I have remote start for the truck to warm up for winter driving so the cab might reach +20 or higher before I would use it. A few miles driving and the cab should be +50 to 60F which is comfortable wearing a winter coat. More than likely I would just bring the radio inside at night if planning to use it the next day. My experience with the TS-180S was that the cold effected the LCD screen so operating was not possible until it warmed. That experience in 1986 was the coldest I have seen in my 36 years up here in AK. Quite possible the temp dropped to -80F at night (-78F is the official record for AK). Fortunately at extreme cold the air is completely calm most of the time. Dog teams coming into the checkpoint reported -45F on the ridge tops but with 30-40mph winds which would feel much colder than what we were down in the lake valley. The coldest I have experience at home on the Kenai Peninsula is -35F and that was nighttime so I stayed inside near the wood stove. I now live in a modern home with force-air natural gas heat and its +67F to +71F year round. Radio gear is std in all vehicles used at Prudhoe Bay on AK's "north slope" but either they leave the engines run continuously or they are plugged in with electric heaters on the inside keeping the interior from freezing. Ever climb into a suburban when the seats are -40F and hard as a rock (a very cold rock)? In fact the seats split apart if allowed to get that cold. Most repeaters up there are enclosed in warmed buildings and only antenna and coax outside. I had fun up there in Nov.1980 installing MOT radios in heavy equipment that was parked outside (it was only -15F so my bare hands took a punishment). After a couple days one of the operators showed me how to start up the engines and I got a little warmth inside the cabs (+15 vs -15). I was young (36) and adventurous - making $6500 in three weeks working 18-hour days didn't hurt, either. 73, Ed - KL7UW From: Richard Fjeld To: "elecraft at mailman.qth.net" Subject: Re: [Elecraft] Cold K3 On 10/4/2016 7:16 PM, Edward R Cole wrote: I've not tried running my K3 at outside temps, Hello Ed, I would caution you against trying your K3 in those temps. Minus 60 degrees F. is the coldest on record for Minnesota, and you experience far colder that that. The cold may do multiple things to the K3 if it has multi-layer circuit boards. I didn't notice if it does. Our club left a repeater in an unheated enclosure one winter. I would estimate it wasn't much colder than minus 30 degrees F. at that location. (To clarify for others, this is 30 degrees F. below zero.) I have seen what the multi-layer circuit board looked like. More specifically, the thru-the-hole solder connections from one layer to another were cracked. Maybe it was the type of solder used??? I'm sure circuit designs have changed since the first solid state rigs I described in the cold. LCD screens hadn't been heard of yet. I'm surprised they don't freeze and get damaged in your temps.

I suspect that Elecraft having not yet published a schematic is simply a matter of time. Schematics for most, if not all, of their products have been published, and the later ones (K3 and later) are on their website as pdf files. DX Engineering does not publish any of their schematics. K3LR , who I consider a good guy, runs that company, and I've let him know what I think about that policy. 73, Jim K9YC On Wed,10/5/2016 9:08 PM, Mike Morrow wrote: > It's just a matter of principal, Phil.

The K3 schematics were published shortly after the release of the K3 itself and have proved invaluable. They have saved me literally hundreds of dollars in return shipping costs for repairs that - thanks to having the schematics - turned out to be very minor and easily done at home. Fast forward to last year when, as an early adopter of the K3S, I was very disappointed to hear afterwards that the schematics would not be published. Having already had to repair the K3S more than once using the old K3 schematics, I can tell you that was no fun at all! Same as Mike, that was not the deal I'd had thought I was buying into. We have a saying in Scotland that "someone needs to have a word with himself" about this. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Mike Morrow >Sent: 06 October 2016 05:08 >To: Elecraft Reflector >Subject: Re: [Elecraft] Camping radio ops: then and now > >Phil wrote: > >> Why "But the KX2 has no schematics for the >> customer, so that prevents my purchase.", Mike? >> Mine works just fine, without schematics. > >It's just a matter of principal, Phil.

And, Mike, I do note with appreciation your many contributions to the K2 odyssey! Alas, times have changes and short of building another K2 that sort of pleasure is no longer available to me: SMT and have not become friends. Sure I'd like to have a KX2 schematic -- and haven't concluded Elecraft won't provide one in time. But I won't deny myself the pleasure of using it -- and pleasure it does provide -- for lack of a schematic. 73, Phil W7OX On 10/5/16 9:08 PM, Mike Morrow wrote: > Phil wrote: > >> Why "But the KX2 has no schematics for the >> customer, so that prevents my purchase.", Mike? >> Mine works just fine, without schematics. > It's just a matter of principal, Phil.

It is designed specifically to charge the Tenergy pack used with the KX2. As a charger, its output runs constant current initially, then it switches to a constant voltage for the final charge push. This type of charger should NOT be used with a KX2 because of the constant current output. The best type of mains-powered for the KX2 to use is an AC adapter, rated 3A or higher. I found that Triad makes a good set of them, and they're available at retailers like Digikey and Mouser. Others on this list have also tested various adapters for RFI, etc. (and DC power quality) and you might check the archives for that info. 73! matt W6NIA KX2 Project Manager On 10/6/2016 3:21 AM, Howard Sherer wrote: > With a change of din plug, can the Tenergy charger for the KX2 be used to > power the KX2 to full power.

The KX3 is designed as a modular "package" and a lot of design intent went towards adding on as the user wishes. The KXPA100 is even easier to work on, being a larger unit with fewer space constraints. In the KX3, I would add the battery charger first, followed by the ATU, then the VHF transverter after that. Take a look at the installation instructions for each, and use the assembly manual as a master guide. You will enjoy using the KX3, I predict! 73! matt W6NIA On 10/6/2016 7:31 AM, Brian ?VE3BWP?

Review your operating aspirations to determine which options will provide the most benefit for you, and in what timeframe. If you have resonant antennas at the home station (or are willing to use a manual tuner initially), then you can put off the KXAT100. If your main immediate goal is for portable operation, I would suggest that the KXAT3 would be a great help as well as the internal battery charger, but if your portable operation is on hold for the Winter, then you can add those next Spring. I am suggesting that you look at the sequence for adding your options in a way that will provide the most benefit for you while adhering to your ham budget. 73, Don W3FPR On 10/6/2016 10:31 AM, Brian ?VE3BWP?

I'd look at and consider moving the roofing filters up on the priority list because of the calibration required. Per the manual page 1 if purchased even as a kit the furnished roofing filter accessory is then furnished calibrated. So look at the roofing filter manual and read the calibration procedure. Would you want to do it at a later date or buy with the original purchase and not have to worry about it. Looking at kit verses factory assembly. If factory assembled was a consideration going for the kit would save 2/3 the price of the roofing filter option. The fun of building the kit and the satisfaction of the first turn on is priceless. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 10/6/2016 12:00 PM, Walter Underwood wrote: > The roofing filters require some calibration.

Thank you both. The original thread was about a K3 operating in the cold below freezing temps, and reduced power was observed. I think the question was asked if we could answer why. Someone posted with a question if the battery was cold. That may have been pertinent. I was curious. I posted about what I had been taught years ago concerning solid state circuit design.

I have an older IC-2800H VHF/UHF radio in my truck. It has a color LCD TV display. The truck is parked on the driveway [a little too long for the garage] and in the winter, I can turn on the radio, and it works, however the display is blank for several minutes until things warm up a little. 73, Fred K6DGW - Sparks NV DM09dn - Northern California Contest Club - CU in the Cal QSO Party 7-8 Oct 2017 - www.cqp.org From farrerfolks at yahoo.com Thu Oct 6 14:34:52 2016 From: farrerfolks at yahoo.com (Mel Farrer) Date: Thu, 6 Oct 2016 18:34:52 +0000 (UTC) Subject: [Elecraft] Soon to be an Elecraft(er)!

How comfortable are you in digging into the building process.? Like Bob said the experience is priceless.2.? Monetarily, you have to way the convenience vs the cost based on your ability to do the assembly.3.? All of the options can be added later, as they have said, it is just a matter of priority. I built the KX3 basic and added the ATU, VHF option and others later and it was a TRIP on first turn on to see I could do it........? Good Luck on your purchase you will not regret it.

I agree with Don on looking at the purchase sequencing.? I'd look at and consider moving the roofing filters up on the priority list because of the calibration required.? Per the manual page 1 if purchased even as a kit the furnished roofing filter accessory is then furnished calibrated. So look at the roofing filter manual and read the calibration procedure.? Would you want to do it at a later date or buy with the original purchase and not have to worry about it.? Looking at kit verses factory assembly. If factory assembled was a consideration going for the kit would save 2/3 the price of the roofing filter option.

However, when you put a roofing filter in the signalling path, it will introduce a further amplitude and phase imbalance (which as you say will be the same for all bands). The per-band nulling parameters you set up before adding the roofing filter will all need to be adjusted to take the impact of the roofing filter into account. This is why you should repeat the whole nulling calibration for each band when you add a roofing filter. Does this make any sense? 73, Matt VK2RQ _____________________________ From: Brendon Whateley Sent: Saturday, October 8, 2016 3:00 am Subject: Re: [Elecraft] Soon to be an Elecraft(er)!

The parts are under voltage and monitored throughout the range. Many of the failures at the very low temp ranges may not be permanent. As the temp is raised the device most of the time functions properly again. There are some anomalies though. We have seen some memory devices work fine at -55C and then lose bits around -40C. And then work fine as the temp rises again. At the high temp end there is greater chance for permanent failure. So, very cold temps can be an issue with any of our gear, especially considering we are using commercial parts. Test temp ranges for semiconductors; Commercial - 0C to +70/80C Automotive - -40C to +125C Military - -55C to +125C 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Edward R Cole Sent: Thursday, October 06, 2016 12:43 AM To: Elecraft at mailman.qth.net Subject: Re: [Elecraft] Cold K3 Dick, The KX3 will not see those extreme cold temps. Where we live it rarely drops below -15F and typically is 0 to +10F at night in winter. The KX3 has a RAM bracket in my truck so it might sit outside at night. I was wondering how it would react to being powered on at down to -15F. Truthfully it might not ever face that as I have remote start for the truck to warm up for winter driving so the cab might reach +20 or higher before I would use it. A few miles driving and the cab should be +50 to 60F which is comfortable wearing a winter coat. More than likely I would just bring the radio inside at night if planning to use it the next day. My experience with the TS-180S was that the cold effected the LCD screen so operating was not possible until it warmed. That experience in 1986 was the coldest I have seen in my 36 years up here in AK. Quite possible the temp dropped to -80F at night (-78F is the official record for AK). Fortunately at extreme cold the air is completely calm most of the time. Dog teams coming into the checkpoint reported -45F on the ridge tops but with 30-40mph winds which would feel much colder than what we were down in the lake valley. The coldest I have experience at home on the Kenai Peninsula is -35F and that was nighttime so I stayed inside near the wood stove. I now live in a modern home with force-air natural gas heat and its +67F to +71F year round. Radio gear is std in all vehicles used at Prudhoe Bay on AK's "north slope" but either they leave the engines run continuously or they are plugged in with electric heaters on the inside keeping the interior from freezing. Ever climb into a suburban when the seats are -40F and hard as a rock (a very cold rock)? In fact the seats split apart if allowed to get that cold. Most repeaters up there are enclosed in warmed buildings and only antenna and coax outside. I had fun up there in Nov.1980 installing MOT radios in heavy equipment that was parked outside (it was only -15F so my bare hands took a punishment). After a couple days one of the operators showed me how to start up the engines and I got a little warmth inside the cabs (+15 vs -15). I was young (36) and adventurous - making $6500 in three weeks working 18-hour days didn't hurt, either. 73, Ed - KL7UW From: Richard Fjeld To: "elecraft at mailman.qth.net" Subject: Re: [Elecraft] Cold K3 On 10/4/2016 7:16 PM, Edward R Cole wrote: I've not tried running my K3 at outside temps, Hello Ed, I would caution you against trying your K3 in those temps. Minus 60 degrees F. is the coldest on record for Minnesota, and you experience far colder that that. The cold may do multiple things to the K3 if it has multi-layer circuit boards. I didn't notice if it does. Our club left a repeater in an unheated enclosure one winter. I would estimate it wasn't much colder than minus 30 degrees F. at that location. (To clarify for others, this is 30 degrees F. below zero.) I have seen what the multi-layer circuit board looked like. More specifically, the thru-the-hole solder connections from one layer to another were cracked. Maybe it was the type of solder used??? I'm sure circuit designs have changed since the first solid state rigs I described in the cold. LCD screens hadn't been heard of yet. I'm surprised they don't freeze and get damaged in your temps.

Do you have firmware 5.14 or later installed in the K3? The current production release is 5.50 which is the recommended firmware at this point. If your firmware is okay, be sure the board is correctly aligned in the socket on the RF board so all the "pins" are engaged. Presumably it all works with the old KSYN3 board in place? IF so, then all that's left is a bad board... 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Michael via Elecraft Sent: Saturday, October 8, 2016 1:19 PM To: elecraft at mailman.qth.net Subject: [Elecraft] New KSYN3a installed and not working / recognized I just installed the new KSYN3a and when I turn on my K3/100/2M rig it does not seem to recognize the board.

I know because I hear relays activated in the KAT500 as soon as I click on a different window.

I can do mode-up and mode-down, or direct-select USB or LSB, but not select either the default mode based on band or the last-used mode based on band (which for me are identical). If I'm operating in RTTY or CW and wish to QSY to an SSB split operation I'd like to be able to include a mode operator in the macro sequence, as I can for every other mode. (MD3; for CW, MD6; for RTTY, etc). But for SSB, since 3 bands are predominantly LSB and 5 are USB, I can't find a way to do this automatically. Is it possible?

When I used it as a rotor loop, I made a couple of hoops around rather than directly flexing the cable around the tower. Not sure if that makes sense. In any case, doing it again I would definitely use a more flexible jumper for the rotor loop running to the antenna. In the shack I'm making jumpers from RG-214 which is very flexible and would work great as a rotor loop as well. 73, Josh W6XU On 10/10/2016 3:14 PM, hsherriff at reagan.com wrote: > OK all.

Commercial practice is to use a flexible jumper and "drip loop" between the feedline and the antenna, even if the antenna is fixed solid to the tower/mast. This relieves the stress on the antenna connector. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From josh at voodoolab.com Mon Oct 10 19:49:07 2016 From: josh at voodoolab.com (Josh Fiden) Date: Mon, 10 Oct 2016 16:49:07 -0700 Subject: [Elecraft] Antenna Question In-Reply-To: <671ab620-59f3-4af5-6aad-25d95577aade@montac.com> References: <1476137691.165213803@webmail.reagan.com> <671ab620-59f3-4af5-6aad-25d95577aade@montac.com> Message-ID: With an unbroken feedline, a failure or antenna swap can require soldering connectors up the tower. Not fun. If you're concerned about the additional loss of a barrel connector at 50MHz, you should be using feedline with lower loss than LMR400 up the tower. Wrap the barrel connection with good quality 3m vinyl tape and paint over with Scotchkote to keep water out.

The closest thing I can think of is to set up the M1-M4 memories for each band. I use M1 for CW mode, M2 for data mode, and M3 for SSB mode - M4 is unused in my case. That will get you to a particular frequency in each band (but it will not be the last used), but will set the mode as you have requested. Once those are set up. you can use the K-pod buttons to send macros which will "push those buttons". Yes, your macros will have to push the M>V button and then the proper M1-M4 button. If your interest is in SSB only, you will only use one of the K-Pod buttons. Each additional mode will require another K-Pod button. I do not use the K-Pod, but I do use the M1-M3 buttons as I have described. My M1 thru M3 buttons send the frequency to somewhere mid-band in each of the mode segments. It is easy to QSY from that point. 73, Don W3FPR On 10/10/2016 12:55 PM, Peter Dougherty wrote: > Hi all, > Just wondering if there's a command to select the last-used phone mode when > creating macro sequences.

Fail to see why an antenna failure or swap would require soldering "up the tower"... unless for some reason you change feedline to antenna connector type.... not likely... or you compromised a connector termination or failed to weather protect properly....

The point was using a lower loss cable for the long run up the tower, such as hardline, then flexible cable for the rotor/drip loop and short distance to the antenna feedpoint. At VHF, this is typical. > Fail to see why an antenna failure or swap would require soldering "up > the tower"... Failure is not necessarily the antenna. It could be the solid center conductor fracture after being flexed too many times :) If you swap antennas and it's a single run of cable, you have to manipulate the antenna on the tower to access the feedpoint. Then, for example, if you put up a longer boom yagi, the feedpoint will most likely be further away from the tower and your existing feedline won't reach. 73, Josh W6XU From josh at voodoolab.com Mon Oct 10 21:42:43 2016 From: josh at voodoolab.com (Josh Fiden) Date: Mon, 10 Oct 2016 18:42:43 -0700 Subject: [Elecraft] Antenna Question In-Reply-To: <889b5c54-ce0b-4f91-2af4-8e3a60c96a97@ptd.net> References: <1476137691.165213803@webmail.reagan.com> <671ab620-59f3-4af5-6aad-25d95577aade@montac.com> <889b5c54-ce0b-4f91-2af4-8e3a60c96a97@ptd.net> Message-ID: Completely agree.

At VHF, this is typical. Right... I'd use the best/lowest loss feedline I could afford/source, too... and then use a smaller jumper... I was simply responding to the OP who said he was using LMR 400.... and saying that LMR-400 CAN and IS frequently used as that "jumper" for the rotator loop... or something similarly sized in the .4-.5 inch range.... >> Fail to see why an antenna failure or swap would require soldering "up >> the tower"... > Failure is not necessarily the antenna.

I'm not a big part swapper/upgrader... I build things the best I can so I don't have to upgrade, so I didn't think of that... This situation would likely not occur for me, as I said above... I would likely NEVER use LMR-400 for a feedline run up a tower.

This isn't RTC drift -- the RTC is fine -- it's the way the display processor keeps the time display in software. If you do a number of things such as changing bands, changing modes, or just tapping the DISP key, the displayed time is corrected to the RTC time. This was reported as a bug, and verified, back in February. While it's considered a medium priority, and it's more or less cosmetic, it's still a source of irritation. It bugs me. I was hoping it would be fixed in the recent betas. It's still present in the recent September beta firmware release. Any ideas on time frames for squashing this bug?

The resistor is used to limit current draw when pin-7 is grounded (inhibiting Tx). With pin-10 directly connected to pin-7, pin-7 will go directly to low when pin-10 does. If you want a little more insurance that current goes the correct direction add a diode pointing toward pin-10 from pin-7.

Then form the coax into a spiral of several turns between the standoffs. Rotation will just tighten or loosen the spiral and not stress the coax at all.

RE: Coax Impedances, Losses, and the Maligning of UHF Connectors. Coax Impedances, Losses, and the Maligning of UHF Connectors by Dick Knadle, K2RIW, 31 May 2001. Coax Impedance -- Concerning the possible choices of the impedance of a coaxial transmission line, a great reference is "Microwave Transmission Design Data", by Theodore Moreno, Dover Publications, 1948. On pages 64 through 69 he discusses four criteria for choosing a particular impedance. The four choices displayed in the graph on page 64 demonstrates how non-critical (broad ranged) many of these impedances are. Most of the following addresses air dielectric coaxial transmission lines. Here are some interesting "Moreno" facts: 1. The maximum continuous power handling occurs at an impedance of 30 ohms. 2. The maximum breakdown voltage occurs at an impedance of 60 ohms. 3. The minimum insertion loss occurs at 77 ohms. 4. The maximum shorted line, resonant impedance occurs at 133 ohms. 5. Conductor losses (in dB's) are proportional to the square root of frequency. 6. Dielectric loss (in dB) is linearly proportional to frequency. Hence, at higher frequencies the dielectric losses become increasingly important. Cable Graphs -- We have all seen graphs of the insertion loss of our favorite cables. They are usually displayed on Log-Log paper with the horizontal axis being frequency, and the vertical axis being insertion loss in dB per 100 feet (or 100 meters). The curious thing is that the insertion loss graph appears as a sloping straight line, with some of the cables displaying a slight upward hook at the highest recommended frequency. Here is the explanation. On Log-Log paper an exponential function appears as a straight line where the slope is proportional to the exponent value. A square root function has a exponent of 1/2. A linear function has an exponent of 1. On most of the cables, only the conductor losses (exponent of 1/2) are significant throughout much of the recommended frequency range. Thus, most of that range is displayed with a slope of 1/2. The hook at the end represents the upper frequency range where the dielectric losses are beginning to kick in. Here the line is beginning to slide into a slope of 1.5, due to the combined effects of the 1/2 slope (conductor losses), plus the 1.0 slope (dielectric losses). Estimating Trick -- Knowing these facts allows you to make some interesting mental approximations. Let's assume you know that your favorite cable has an insertion loss of 1.0 dB per 100 feet at 144 MHz. If your friend asks you what's the approximate loss at 432, here is what you can do. Since you know that the cable is usable to at least 2 GHz, you assume that conductor losses dominate throughout most of the 144 to 432 frequency region, and conductor loss is proportional to the square root of frequency. 432 MHz versus 144 MHz is a 3:1 frequency ratio. The square root of 3 is 1.73. Multiply the 144 MHz loss (1.0 dB) by the 1.73 factor, and you come up with a predicted approximation of 1.73 dB per 100 feet at 432 MHz. Because there will be a slight contribution due to dielectric losses at this end of the cable's operating range you could round your prediction up to 1.75 dB per 100 feet. Try this procedure on the graphs of your favorite cables and you will be amazed how close the approximation usually is. Cut-Off Frequency -- As you go beyond the manufacturer's upper recommended frequency, the cable is capable of acting like a round piece of wave guide (WG). The presence of the center conductor adds a little capacitive loading that slightly lowers the WG cut-off frequency. Moreno recommends using this approximate equation for predicting the cut-off wavelength: Lambda = Pi * (a + b). a = outer radius of the center conductor. b = inner radius of the outer conductor. Pi = 3.1416 ... In other words, the limiting wavelength is approximately equal to the circumference at the arithmetic mean diameter. Coaxial WG -- Now, don't let this limitation always scare you into submission. The cable isn't going to explode if you use it above the recommended frequency, it just gets a little tricky up there. The first wave guide (WG) mode to consider is the TE11 circular mode. That's the one used by the 10 GHz guys who are using 3/4 inch water pipe as a poor man's wave guide -- it turns out to be a very high quality [low loss] wave guide. In the TE11 WG mode the maximum E-field lines flow from the 6 o'clock position to the 12 o'clock position in the pipe (vertical polarization is assumed). If your coax cable doesn't have any significant bends in it, and the inner conductor is centered, it won't launch any E-field (WG mode) at right angles to the center conductor. Your next question is "what's a significant bend?" The microwaver's are going to have to study this, but, my gut feel is that a bend radius of greater than 1 foot is OK. It is just a matter of time until some smart amateur intentionally launches both propagation modes in a piece of coax in order to lower the over-all insertion loss. It will require some careful tuning of the launching structures at each end of the cable to insure that the two modes end up co-phase at the top of the tower. This is because the phase velocity of the WG mode is faster than the coaxial mode. This technique can only be applied to a narrow band situation, or a set of narrow band situations (like 5 GHz and 10 GHz). UHF Connector Maligning -- There are many misinformed engineers and amateurs who have been led to believe that a UHF connector is the worst thing ever invented in the RF world -- due to it's lower internal impedance. They believe that each UHF connector causes a 1/2 dB insertion loss and a whole lot of VSWR at 432 MHz. I've heard quite a few amateurs claim that their 432 MHz brick amplifier will now have 1 dB greater gain since they just replaced the two chassis mounted UHF connectors with Type N connectors. This "Old Wive's Tale" has been propagated for decades. Everyone believes it. No one challenges it. Few people have ever make the measurement. A High Power "Calorimetry" Test -- Here is my observation. I took a 432 MHz Stripline Parallel Kilowatt Amplifier and applied 700 watts through a UHF female and a UHF male connector, and then into my antenna feed line. After 10 minutes of 700 watts throughput power the UHF connectors were mildly warm. If I estimate that "mildly warm" represents a dissipation of 3 watts out of 700 watts, that's an estimated insertion loss of 0.019 dB for the pair of connectors. You're about to ask, "how can this be, the internal dimensions are approximately a 35 ohm impedance, it's got to cause a 1.43:1 VSWR?" Well, it doesn't. Very Little Total System VSWR -- The mated UHF connector has an internal connector length of less than 0.9 inches. A free space wavelength at 432 MHz is 27.3 inches. The 0.9 inches represents a phase length of 11.9 degrees. If I plot this up on a Smith Chart (or use the mathematical equivalent) I find the following. A 50 ohm antenna with an 11.9 degree long section of 35 ohm line causes an input impedance of (47.9 -j7) ohms. That's an input VSWR of 1.16:1, which gives a worse case reflected-power-caused transmission loss of 0.024 dB. To me that's insignificant. Now, I'll admit that at 10 GHz, where the wavelength is 1.1 inches, that 0.9 inch electrical length connector would be much harder to tolerate. Power Tolerance -- A Type N connector can tolerate low-duty pulses of over 20 kilowatts without a voltage break down. However, steady state power of more than 1 kW could cause the connector to fail from the RF current overheating the center pin. Most connectors have a very similar failure mechanism when steady state high RF power is applied. The UHF connector has an oversized center pin that can more easily tolerate high steady state RF currents. Moreno said that 30 ohms impedance maximizes the power handling, and the UHF connector has an impedance of about 35 ohms. Each EME'er who is using those expensive type SC connectors on his kW amplifier could probably use UHF connectors for his indoor cable attachments, if he desired to save money. The UHF connector has a larger center pin than an SC connector, it might actually have a larger power tolerance than the SC -- this will require testing. But, remember that the Fluoroloy-H dielectric on the SC connector is designed to be a good heat sync that cools the center pin. It's User Friendly Assembly -- There are probably twice as many amateurs who can do a good job of installing a UHF connector on an RF cable, as compared to a Type N connector. The proper installation and WX proofing of a Type N connector requires considerable finesse and experience. It's almost an art form. UHF Connector Faults -- There are two major faults I can find with a UHF connector when it is being used on 432 and below: (1) the lack of weather proofing; (2) the lack of outer conductor finger contactors. With a proper tape wrapping job, I believe the weather proofing can be accommodated. However, the user must be sure that the internal "teeth" are properly seated, and that the outer nut is kept tight; otherwise the outer conductor can develop a considerable growth in electrical length, with the associated "scratch contacting" noise. For this reason the connector is probably inappropriate for a high vibration environment, unless an auxiliary nut-retaining mechanism is employed. So, maybe it's time we stop saying such bad things about the poor-orphaned UHF connector. For our purposes, it doesn't deserve all that flack. Properly used by a savvy engineer, who understands the idiosyncracies, it can give you a lot of bang for the dollar. It's been around for 60 years, that's no coincidence. I welcome alternate opinions on all of the above. Please feel free to correct the mistakes. 73 es Good VHF/UHF/SHF DX, Dick, k2RIW. Grid: FN30HT84DC27. APPLICATION NOTES: 1. UHF Connector VSWR at 432 MHz A 15 db return loss from a UHF connector that's being used at 432 MHz is quite good in many circumstances. That return loss (a 1.43:1 VSWR) only causes an insertion loss of 0.14 dB (before correction, such as re-tuning the transmitter). On the transmitter side of an EME system, you'll never know it's there. But, if there was a 15 dB return loss caused by a connector that's in front of a well tuned LNA, that is significant. It could make a considerable difference to the system's Noise Figure, if the operator did not apply VSWR corrective action -- such as tuning the LNA for best Noise Figure performance while it is connected to the real system. However, I suspect that very few of the currently operation EME antenna systems have a return loss of better than 15 dB -- particularly not during rain and snow. Therefore, that savvy EME operater has had to apply corrective action to the total antenna system, if he wants full performance of his LNA. If the UHF connector is part of that antenna system, it will get lumped together within that corrective procedure. Thus, that connector 15 dB return loss could be very tolerable to a well-informed operator. 2. More 50 Ohm Magic, UHF Connectors Introduction -- In various responses to my 31 May 2001 treatment of UHF connectors, cogent comments were made that I wish to address, and add to. Connector Brands -- Since the UHF connector doesn't seem to be protected by a MIL Specification, there is a wide variation in the quality and mechanical performance of the connectors that are available on the world wide market. The buyer must be wary. I hope that a savvy amateur will create a web site list that will inform us of the UHF connector brand names, and sources, that are worthy of our hard-earned money. Lloyd, N5GDB, and Lloyd, NE8I both strongly recommend the silver plated or gold plated versions, particularly with respect to solderability and connection integrity. Installation -- I probably was too hasty when I stated that twice as many amateurs/engineers can properly install a UHF connector versus a type N connector. An experienced RF maven (one who has a "feel" for the way RF flows) can almost always suggest an improvement in the connector installation procedure -- so that the lowest VSWR, least loss, best mechanical strength, best longevity, and best weather proofing are realized. Most of my outdoor equipment uses type N connectors, with BNC's most used indoors, and SMA's used within enclosures. For the few UHF connectors that I use, here is my favorite connector installation method. (1) After properly cutting back the braid and dielectric, I next tin the braid (and center conductor) with as little solder as possible, that will still coat the strands. Since the end of the cable is completely open to air at this point, the amount of melting of the polyethylene dielectric is minimized. (2) I slip the nut onto the cable and then screw on the connector body. The tinned braid causes extra resistance, and a strong pair of pliers are definitely required. (3) Assuming that I've chosen a connector brand that readily accepts solder, the process of tack-soldering through the 4 holes requires very little heating time, when using a large-enough, hot-enough, soldering iron. Thus very little further melting of the polyethylene dielectric takes place, and the complete braid is essentially bonded to the connector body. (4) Clean off as much solder from the tip of the iron as possible, and heat up the side of the center pin, while applying solder down the front hole. Try to keep solder off the side of the center pin. If need be, wipe off any excess while it is hot. Excess solder left on the outside of connector center pin will interfere with the proper mating with the female connector. A further benefit of the braid tinning process is that the strands of the braid don't become scattered, spread, and folded back during the process of screwing on the connector body. Thus, full braid strength, and electrical bonding is assured by this process. I suspect that other experts have further improvements on this process, and I welcome their comments. Crimp Connectors -- For indoor, non-critical applications I believe that crimp connectors can be very expedient and handy. However, the crimping process has a number of characteristics that bother me: (A) True UHF Frequency VSWR -- For many crimp connector designs the outer braid is crimped quite far back from the end of the cable. This creates an outer connector choke assembly that makes the outer conductor longer than the center conductor. (B) Salt Spray Survival -- My previous salt mine (the former AIL System Inc., now EDO-Electronic Systems Group) performed a number of salt spray tests a few years ago on crimp-connected semi-rigid cables. The results were not encouraging. In a number of the cables the UHF or SHF VSWR changed considerably after a few cycles of the salt spray exposure. It is hard to beat the RF bonding that a solder joint creates. (C) Ultimate Shielding Requirement -- Arguably, the most critical requirement for an indoor connector is that of the jumper cables on a repeater's duplexing filter. In this application you desire the connector to provide 110 dB of shielding integrity (if you can get it). I personally have experienced repeaters that would develop "scratchy interference" and RCVR desensitization as the type N crimp connected jumpers were manually moved. Lloyd, NE8I also mentioned these problems concerning silver plating. On the two occasions that I experienced this, the problem was cured when the jumpers were replaced with well-installed conventional type N connectors. I have been told of desperate repeater owners who used conventional type N connectors, but modified them by soldering the internal collet assembly to the cable braid before assembling the connector, as a way of avoiding any oxidation-caused scratchy braid connections. (D) Weather Proofing the Crimp -- In a conventional type N connector, the portion that consists of the compression bond of the braid and the internal collet is all contained within the weather-proof portion of the connector. However, in most crimp-type connectors, the crimped portion of the cable's outer conductor is exposed to the weather. This suggests that the crimped joint is subject to corrosion, and a subsequent poor connection. Most of us will tape and shrink-wrap our outdoor type N connectors as a "belt and suspenders" approach to secondary weather proofing. In the case of a crimped connector, our weather proofing of the outer braid is a primary protection requirement. My (Crimp) Conclusion -- If we do a really good job of installing a connector on an outdoor coaxial cable, we are likely to use that cable for 10 to 15 years. A crimp connector is capable of saving you a considerable amount of time during the initial installation. However, if the crimp connector gives you trouble within the first few years of service (that's what the salt spray tests suggest), than the time saving during the installation of a crimp connector might really be a false economy. I'm willing to spend an extra 10 minutes installing a connector, if it is likely to give me over 10 years of service. Here is my challenge. Does anyone know of a well documented set of salt spray tests that were performed on various stiles of RF coaxial cable crimp connectors? A salt spray test is a beautiful way of artificially putting 10 years of aging into a cable assembly within a week. Many of us live within a hundred miles of a sea shore, and this characteristic is important to us. I'll admit that the Microwavers who live in the Mojave Desert may not have this particular problem to worry about. Mismatch -- Leonard, N3NGE spoke of the difficulty of sweeping a cable system that has a high return loss connector at the beginning. Jerry, K0CQ suggested that the problem can be overcome with a Time Domain Reflectometer (TDR), and it will even display the water that is within a section of the cable. I've spent a few years of my life using TDR's and I love'em. They can make RF measurements that will amaze you. However, they are expensive, rare on the surplus market, and few colleges even mention this wonderful instrument. That's unfortunate. A really good TDR will allow you to inspect the integrity of your transmission line system at possibly every 1/8 inch at a time, and it will "look through" that poor connector that's at the beginning of the cable. There are TDR "De-Embedding Techniques" that will allow you to inspect portions of your cable that are surrounded by some pretty significant mismatches. There is a solution for us amateurs, it's called the Steinhelfer Technique. If you sweep the cable, and stop at say 1,024 separate frequencies, and measure the amplitude, and phase of the reflected power, you now have a data set that can do magic. Apply this data set to a computer program that performs a type of Fourier Transform, and it will simulate a TDR that is far above the performance of the one that you could afford. We have all seen those fairly inexpensive hand held VSWR Sweeper-Plotter machines. Add a phase measurement capability, and an RS-232 port to that machine, and you're almost there. That modified hand held device will gather the raw data, and a PC could process the data and make up the TDR plots. A VSWR plotter that sweeps 1 to 1,000 MHz could give you the capability of resolving what's going on in your transmission line system every 6 inches. For most of us, that's good enough to locate a faulty section. Sweep the data gatherer from 1 to 2,000 MHz, and you will resolve every 3 inches, etc. It's about time that somebody offers this as a new RF toy for our pleasure. I'll admit that the Steinhelfer technique involves some fairly heavy mathematics. But, it can be taken in stages, and you could share the responsibility. Just assemble an RF maven, a mathematician, and a Computer Science major, and point them in the right direction. This would make a fantastic Senior Project for a group of engineering students. Later, it might even make them rich. For those who wish to study this further, see the following references: (1) HP Application Note 62, "Time Domain Reflectometry", 1964.

I am not sure on the connection from the k3 to acom. I ran a 1010 for a while for CQP, only on SSB, so I can't comment on delay time. A simple RCA to RCA connector from the K3 to the 1000 is all that is needed to key the amp. You are correct that ALC should NOT be used between the K3 and the amp. This is true of virtually ALL rigs and amps. Using ALC to set power is a recipe for splatter and clicks. 73, Jim K9YC From jim at audiosystemsgroup.com Tue Oct 11 12:36:28 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 11 Oct 2016 09:36:28 -0700 Subject: [Elecraft] Antenna Question In-Reply-To: <003001d223c3$7c6d79f0$75486dd0$@erols.com> References: <1476137691.165213803@webmail.reagan.com> <671ab620-59f3-4af5-6aad-25d95577aade@montac.com> <04433fde-8c78-328d-1755-0465ab3374d5@audiosystemsgroup.com> <003001d223c3$7c6d79f0$75486dd0$@erols.com> Message-ID: <98058a7c-5944-4779-6595-1d69a6fa9c14@audiosystemsgroup.com> On Tue,10/11/2016 6:29 AM, Charlie T, K3ICH wrote: > I'm curious as to exactly why a "junk" connector supposedly has so much more loss than a "good" connector?

China RF do some good ones via Fleabay too. We use these extensively in our 6Gs DXpeditions, together with compression type PL259s. A side benefit is that it's easy to terminate the coax feed from multiple station in female connectors (forming a 'patch panel' in effect) so there is zero risk of cross-coupling 2 stations. My own station has mostly been converted to compression types; but there are Amphenols in there too. Motivation to change? Ease of waterproofing the compression types.

Forgive me if this has been closed.) This caught my eye, and I agree. I have found when buying PL-259's that are made in a 'metric' country, there can be slight problems converting to the dimensions used in North America. I have chased SWR troubles almost in circles only to find the tip of an imported PL-259 was making intermittent contact with the SO-239 socket. A simple fix was to apply a bit of solder to the tip and then file it down until I could feel a gentle friction as I plugged it into the socket. Another important item in a PL-259 is a good tinned surface for soldering. I like the so called 'silver plated' plugs when I can find them. I don't know if they are truly silver plated, but they do take solder beautifully.

You can then install whatever apps you like (as long as they aren't too graphics-hungry), and give that machine 'direct access' to whatever hardware devices you need to - serial ports, USB ports etc. I'm not, as it happens, aware of any 'emulators' that let you run individual apps as if they were running in Windows, but a VM is cleaner (and you'll not have issues with drivers because every device becomes a generic device once the VM hypervisor starts passing it through). 73, and a firm left handshake, John (XLX) -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Dauer, Edward Sent: 12 October 2016 17:21 To: elecraft at mailman.qth.net Subject: [Elecraft] Windows Emulator I give up.

I use Parallels as the virtual machine. It works fine. It allows you to run each Window's program in a separate window on the Mac screen or you can run all Windows programs under one window. If you are just running one Window's program it works fine but once you start multi-tasking it can be a problem particularly if the programs are graphic intensive or memory hungry. I often found the computer slowed up too much and gave up on the idea hence the stand alone computer. 73, Tom KQ5S On Wed, Oct 12, 2016 at 11:20 AM, Dauer, Edward wrote: > I give up. > > I have tried to be faithful to my decision of a few years ago, to swear > off Windows and work exclusively with Mac OS.

As John said, there are several options. I?ve never used the Oracle product, but for quite a few years I?ve been running the VMWare product called Fusion. Currently running on a 27? late 2012 iMac with 8GB RAM. I have several Ubuntu Linux guests in addition to a Windows 10 guest that run on this setup. I?ve got quite a few Windows-only applications that I use the Win10 guest for. In all these years I?ve never come across an application that would not run as a guest under Fusion. I?ve got the applications on the ARRL Handbook and Antenna book, EZnec, and the software that controls my AIM-4170 antenna analyzer, in addition to other applications - all work fine. My logging is done on the Mac OS side - I use MacLoggerDX. Several months back I built a couple little SDR rigs and drove them with software running on both Windows and Linux. I used a logging program called CQRlog for logging those QSO?s. It was a simple matter to export the ADIF records from CQRlog and put them into MLDX when I was done operating the SDR. Give Fusion a shot - works great! 73, Jim / W6JHB Folsom, CA > On Wednesday, Oct 12, 2016, at Wednesday, 9:30 AM, John wrote: > > Hi Ted, > > I wouldn't bother with an 'emulator' as such, instead what I'd do is go and grab some virtualisation software (personally I use Oracle's Virtualbox), and install a full copy of Windows inside that.

Your Mac is no more secure than a Windows computer (and in fact Apple collect a lot of data and hide the fact that they're collecting it, they just manage to hide it better than Microsoft do). Your assertion that you're safe just because you use a Mac is, at best, a false belief. I, and many other people, use a Windows PC on a daily basis, do all my online shopping on it etc, and I've not been a victim of any of the things you suggested will happen. Sure, I'm a careful user (by which I mean I apply common sense when browsing etc), but I'm at no more risk on my Windows PC than you are on your Mac. In response to Dick's question about cost, the only cost would be a Windows licence. With Windows 10 being free for a long time, you may still find that your VM can install, and be activated with, that for free. YMMV. Virtualbox is completely free to individual users (and I suspect other VM hypervisors mentioned in the thread such as Parallels and VMware Fusion are the same). 73, and a firm left handshake, John (XLX) -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Michael Wong Sent: 12 October 2016 17:56 To: Richard Fjeld Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] Windows Emulator I second that.

I am buying almost all my connectors from Dave's: http://www.daveshobbyshop.com/ Quite often at a savings in price and very rapid shipping. Another comment on elbow adapters: I initially used a gold-plated sma male elbow on the 2m connection for my KX3 wondering why output was low. I switched to using a short run of .141 rigid coax with sma connectors and get less loss.

I've not used VirtualBox, but have friends who have great success. Virtualization has some big advantages: You can isolate different things you do to different virtual machines. Probably the best example of that is to keep your financials away from general browsing and E-Mail where you might encounter viruses or trojans. You can always experiment with downloaded software in a VM and destroy the VM if you think the download did more than you expect. When you replace a computer, all of the VMs are just a set of files that can be copied to your new computer. 73 -- Lynn On 10/12/2016 9:50 AM, James Bennett wrote: > Ted, John, et al - > > Don?t give up!

I too use professionally (for testing) Oracles excellent VirtualBox - it is decent VM which for home use will allow you to try almost any OS you wish to dabble in. VMWares?s products are also excellent - but are generally tailored for commercial/large scale VM applications. There are others KVM, MVS, Hyper-V etc Do not stress about hypervisor 1 or 2 - You will use a level 2 hypervisor - just accept that and carry on forwards. The only caveat with home VM?s are these a) You are always running 2 machines - you have the physical machine which requires resources such as CPU, memory and disk - plus you have the VM which also needs the same. So you need to make sure you balance the load between the two. b) If you ?host? i.e. the machine where the VM software is installed can not see the device on a USB etc because there is no driver etc - then you will not be able to utilize this device inside the VM software. c) You often get what is termed ?VM-bloat? as you create a machine to run a skimmer, then another for Product-X - oh and another for product-Y - so keep an eye on your disk utilization - I used a separate 1Tb drive just to handle the 30+ VM?s I use !! So what have you got to loose - except a little disk space and time Best regards Tim - A45WG > On Oct 12, 2016, at 8:20 PM, Dauer, Edward wrote: > > I give up. > > I have tried to be faithful to my decision of a few years ago, to swear off Windows and work exclusively with Mac OS.

This should suffice unless you have an extremely low noise floor. If you do, then you can install the KXV3B option, which has a second preamp that has a much better MDS -- around -144 to -145 dBm. The K3S comes with the KXV3B option. 73, Wayne N6KR On Oct 12, 2016, at 5:46 PM, KC6CNN wrote: > I am curious why a fellow ham and I who both live within two blocks of each > other and have the same wire antenna, Except mine is a little higher.

The outboard preamp for the K3 solved that problem, but the new preamp that's part of the KXV3B module does it even better. I've upgraded my K3s to the new KXV3B, and am very happy. My QTH is pretty quiet except when I point the Yagi in the direction of my neighbor's solar system. In those quiet directions, the preamp adds several dB of weak signals that I wouldn't hear without it. Before that, I had a ARR GasFET preamp in front of the radio I used on 6M that also worked on 10M, and it was at least as good as the new preamp. So the executive summary is, "yes, the K3 doesn't hear very well on 10 and 6 without a preamp." 73, Jim K9YC On Wed,10/12/2016 9:49 PM, Bill Frantz wrote: > If you are hearing static, then you have enough sensitivity.

I bought the PR6-10 from a ham who was upgrading to the KXV3B. It made my K3 (SN 4340) circa 2010 much better on 10m and 6m. I even copied some 6m-eme* signals with the PR6-10 using my 6-element yagi in August of 2015. I now have a 6m GasFet preamp at tower top and it is a little bit better but only noticeably on 6m-eme. It has a little more gain so my s-meter runs higher with noise, but on terrestrial contacts can't say its any better than the PR6-10 (which also helps 10m). Before getting either preamp 10m was pretty quiet of signals (with Hygain TH3mk4). What is interesting is my KX3 does as well or maybe slightly more sensitive on 6m (of course with internal preamp on). *Note: now QRV on 6m-eme with 900w. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From david at aslinvc.com Thu Oct 13 06:55:23 2016 From: david at aslinvc.com (David Aslin G3WGN) Date: Thu, 13 Oct 2016 10:55:23 +0000 Subject: [Elecraft] Antenna Question In-Reply-To: References: <1476137691.165213803@webmail.reagan.com> <671ab620-59f3-4af5-6aad-25d95577aade@montac.com> <04433fde-8c78-328d-1755-0465ab3374d5@audiosystemsgroup.com> <3A4955B4-9182-441B-B814-17DBD28B0F57@widomaker.com> <0670a139-718b-7ce1-3481-f84040c1bc40@voodoolab.com> <1476222614605-7623260.post@n2.nabble.com> <971906579.525528.1476260264332.JavaMail.open-xchange@oxbe7.tb.ukmail.iss.as9143.net> Message-ID: Danny, Glad you like them.

It may have a problem saving TX/RX EQ settings, but I'm not sure. I always liked the program, which was developed by N2BC. It hasn?t been updated for a long time. For those not familiar with it, here?s a summary of the features from the help file: Overview: K3EZ is designed to provide the following basic functions: * A simple frequency ?Stacking? function with most of the K3 front panel buttons available to ?click and change? * An easy to use frequency memory database * An easy to use graphic display and Set and Get of RX and TX Equalizers with a saved setting database * Basic K3 information (COM port, Firmware levels, installed options, filters, etc.) * A formatted and functionally organized display of the majority of the K3 CONFIG settings * An easy to use K3 Command Utility, formats K3 responses in ASCII or HEX * SWR Scan function to sample and graph SWR With the exception of the K3 RX and TX equalizers, the program DOES NOT change K3 CONFIG settings. It does provide easy to use access to the settings, but YOU make the changes! 73, Jim N7US -----Original Message----- Has anyone gotten K3 EZ to run under Windows 10?

Do the research.... There's all kinds of info on how to create/route a feedline for rotator use... Most of the people I know with tall towers and big antennae use LMR-400 (or similar size) AS the "smaller jumper".

Commercial practice is to use a flexible jumper and "drip loop" between the feedline and the antenna, even if the antenna is fixed solid to the tower/mast. This relieves the stress on the antenna connector. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ------------------------------ Message: 4 Date: Mon, 10 Oct 2016 16:49:07 -0700 From: Josh Fiden To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Antenna Question Message-ID: Content-Type: text/plain; charset=windows-1252; format=flowed With an unbroken feedline, a failure or antenna swap can require soldering connectors up the tower. Not fun. If you're concerned about the additional loss of a barrel connector at 50MHz, you should be using feedline with lower loss than LMR400 up the tower. Wrap the barrel connection with good quality 3m vinyl tape and paint over with Scotchkote to keep water out.

If you really want to get picky, the 400 should come up to the connector [sealed of course] and supported on the tower, and then the jumper forms the drip loop to prevent water running down the coax from running over ... and eventually into ... the connector. I don't think I'd run 400 all the way to a rotating antenna. 73, Fred K6DGW Sparks NV USA Washoe County DM09dn On 10/10/2016 4:34 PM, Phil Kane wrote: > On 10/10/2016 3:14 PM, hsherriff at reagan.com wrote: > >> Would you connect the LMR to the antenna and allow it to move with the rotation, or run a short length of something much more flexible between the antenna and LMR? > > Commercial practice is to use a flexible jumper and "drip loop" between > the feedline and the antenna, even if the antenna is fixed solid to the > tower/mast.

The closest thing I can think of is to set up the M1-M4 memories for each band. I use M1 for CW mode, M2 for data mode, and M3 for SSB mode - M4 is unused in my case. That will get you to a particular frequency in each band (but it will not be the last used), but will set the mode as you have requested. Once those are set up. you can use the K-pod buttons to send macros which will "push those buttons". Yes, your macros will have to push the M>V button and then the proper M1-M4 button. If your interest is in SSB only, you will only use one of the K-Pod buttons. Each additional mode will require another K-Pod button. I do not use the K-Pod, but I do use the M1-M3 buttons as I have described. My M1 thru M3 buttons send the frequency to somewhere mid-band in each of the mode segments. It is easy to QSY from that point. 73, Don W3FPR On 10/10/2016 12:55 PM, Peter Dougherty wrote: > Hi all, > Just wondering if there's a command to select the last-used phone mode when > creating macro sequences.

IF you are using LMR-400 as the main feedline, there is NO REASON to use a different diameter at the rotator... I was simply responding to what the OP said were the conditions... NOT the "ideal"... Bottom line... IF you engineer and install things properly, the fewer breaks in the feedline, the better... Fail to see why an antenna failure or swap would require soldering "up the tower"... unless for some reason you change feedline to antenna connector type.... not likely... or you compromised a connector termination or failed to weather protect properly.... In either case, your odds of doing one of those things increase with every additional connector you add to the line. BTW, using the -DB suffix (if available) for any Times cable will radically reduce the chances of moisture ingress on the feedline... ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 10/10/2016 6:49 PM, Josh Fiden wrote: > With an unbroken feedline, a failure or antenna swap can require > soldering connectors up the tower.

The point was using a lower loss cable for the long run up the tower, such as hardline, then flexible cable for the rotor/drip loop and short distance to the antenna feedpoint. At VHF, this is typical. > Fail to see why an antenna failure or swap would require soldering "up > the tower"... Failure is not necessarily the antenna. It could be the solid center conductor fracture after being flexed too many times :) If you swap antennas and it's a single run of cable, you have to manipulate the antenna on the tower to access the feedpoint. Then, for example, if you put up a longer boom yagi, the feedpoint will most likely be further away from the tower and your existing feedline won't reach. 73, Josh W6XU ------------------------------ Message: 12 Date: Mon, 10 Oct 2016 18:42:43 -0700 From: Josh Fiden To: Elecraft Reflector Subject: Re: [Elecraft] Antenna Question Message-ID: Content-Type: text/plain; charset=windows-1252; format=flowed Completely agree.

At VHF, this is typical. Right... I'd use the best/lowest loss feedline I could afford/source, too... and then use a smaller jumper... I was simply responding to the OP who said he was using LMR 400.... and saying that LMR-400 CAN and IS frequently used as that "jumper" for the rotator loop... or something similarly sized in the .4-.5 inch range.... >> Fail to see why an antenna failure or swap would require soldering "up >> the tower"... > Failure is not necessarily the antenna.

I'm not a big part swapper/upgrader... I build things the best I can so I don't have to upgrade, so I didn't think of that... This situation would likely not occur for me, as I said above... I would likely NEVER use LMR-400 for a feedline run up a tower.

If you do a number of things such as changing bands, changing modes, or just tapping the DISP key, the displayed time is corrected to the RTC time.

I also have used Davis FLEX LMR400 equivalent and if I remember correctly Davis-FLEX that is what is stamped on the feedline. The difference between LMR400 solid center conductor and LMR400 FLEX stranded center conductor has a loss of about .1 or .2db more at 50 MHz. Again if my memory is correct.

"Good" means Amphenol 83-1SP for the PL-259s, and Amphenol or surplus MIL-spec for the barrels.

The connectors were Amphenol 83-1SP that I soldered myself. To test those cables, I spliced them together using Amphenol barrels and measured the loss of about 1300 ft of cable up to 500 MHz using HP generator and spectrum analyzer. The measured loss was LESS than the manufacturer's spec. There were 27 83-1SPs and 13 barrels in line.

Just set K3's power output to a level your Acom 1000 is satisfied with. Make sure not to overdrive the Amp. Find the maximum drive level in the manual of your Acom.

They're probably both (nickel, silver ???) plated brass with a dielectric insulator usually Teflon, phenolic or ?? Is it the plating, the insulator, the fit of the threads, the solder-ability, or what, that makes the lossy? I can understand it if the dimensions are way off or they don't thread on properly, but that should be obvious in the installation process.

RE: Coax Impedances, Losses, and the Maligning of UHF Connectors. Coax Impedances, Losses, and the Maligning of UHF Connectors by Dick Knadle, K2RIW, 31 May 2001. Coax Impedance -- Concerning the possible choices of the impedance of a coaxial transmission line, a great reference is "Microwave Transmission Design Data", by Theodore Moreno, Dover Publications, 1948. On pages 64 through 69 he discusses four criteria for choosing a particular impedance. The four choices displayed in the graph on page 64 demonstrates how non-critical (broad ranged) many of these impedances are. Most of the following addresses air dielectric coaxial transmission lines. Here are some interesting "Moreno" facts: 1. The maximum continuous power handling occurs at an impedance of 30 ohms. 2. The maximum breakdown voltage occurs at an impedance of 60 ohms. 3. The minimum insertion loss occurs at 77 ohms. 4. The maximum shorted line, resonant impedance occurs at 133 ohms. 5. Conductor losses (in dB's) are proportional to the square root of frequency. 6. Dielectric loss (in dB) is linearly proportional to frequency. Hence, at higher frequencies the dielectric losses become increasingly important. Cable Graphs -- We have all seen graphs of the insertion loss of our favorite cables. They are usually displayed on Log-Log paper with the horizontal axis being frequency, and the vertical axis being insertion loss in dB per 100 feet (or 100 meters). The curious thing is that the insertion loss graph appears as a sloping straight line, with some of the cables displaying a slight upward hook at the highest recommended frequency. Here is the explanation. On Log-Log paper an exponential function appears as a straight line where the slope is proportional to the exponent value. A square root function has a exponent of 1/2. A linear function has an exponent of 1. On most of the cables, only the conductor losses (exponent of 1/2) are significant throughout much of the recommended frequency range. Thus, most of that range is displayed with a slope of 1/2. The hook at the end represents the upper frequency range where the dielectric losses are beginning to kick in. Here the line is beginning to slide into a slope of 1.5, due to the combined effects of the 1/2 slope (conductor losses), plus the 1.0 slope (dielectric losses). Estimating Trick -- Knowing these facts allows you to make some interesting mental approximations. Let's assume you know that your favorite cable has an insertion loss of 1.0 dB per 100 feet at 144 MHz. If your friend asks you what's the approximate loss at 432, here is what you can do. Since you know that the cable is usable to at least 2 GHz, you assume that conductor losses dominate throughout most of the 144 to 432 frequency region, and conductor loss is proportional to the square root of frequency. 432 MHz versus 144 MHz is a 3:1 frequency ratio. The square root of 3 is 1.73. Multiply the 144 MHz loss (1.0 dB) by the 1.73 factor, and you come up with a predicted approximation of 1.73 dB per 100 feet at 432 MHz. Because there will be a slight contribution due to dielectric losses at this end of the cable's operating range you could round your prediction up to 1.75 dB per 100 feet. Try this procedure on the graphs of your favorite cables and you will be amazed how close the approximation usually is. Cut-Off Frequency -- As you go beyond the manufacturer's upper recommended frequency, the cable is capable of acting like a round piece of wave guide (WG). The presence of the center conductor adds a little capacitive loading that slightly lowers the WG cut-off frequency. Moreno recommends using this approximate equation for predicting the cut-off wavelength: Lambda = Pi * (a + b). a = outer radius of the center conductor. b = inner radius of the outer conductor. Pi = 3.1416 ... In other words, the limiting wavelength is approximately equal to the circumference at the arithmetic mean diameter. Coaxial WG -- Now, don't let this limitation always scare you into submission. The cable isn't going to explode if you use it above the recommended frequency, it just gets a little tricky up there. The first wave guide (WG) mode to consider is the TE11 circular mode. That's the one used by the 10 GHz guys who are using 3/4 inch water pipe as a poor man's wave guide -- it turns out to be a very high quality [low loss] wave guide. In the TE11 WG mode the maximum E-field lines flow from the 6 o'clock position to the 12 o'clock position in the pipe (vertical polarization is assumed). If your coax cable doesn't have any significant bends in it, and the inner conductor is centered, it won't launch any E-field (WG mode) at right angles to the center conductor. Your next question is "what's a significant bend?" The microwaver's are going to have to study this, but, my gut feel is that a bend radius of greater than 1 foot is OK. It is just a matter of time until some smart amateur intentionally launches both propagation modes in a piece of coax in order to lower the over-all insertion loss. It will require some careful tuning of the launching structures at each end of the cable to insure that the two modes end up co-phase at the top of the tower. This is because the phase velocity of the WG mode is faster than the coaxial mode. This technique can only be applied to a narrow band situation, or a set of narrow band situations (like 5 GHz and 10 GHz). UHF Connector Maligning -- There are many misinformed engineers and amateurs who have been led to believe that a UHF connector is the worst thing ever invented in the RF world -- due to it's lower internal impedance. They believe that each UHF connector causes a 1/2 dB insertion loss and a whole lot of VSWR at 432 MHz. I've heard quite a few amateurs claim that their 432 MHz brick amplifier will now have 1 dB greater gain since they just replaced the two chassis mounted UHF connectors with Type N connectors. This "Old Wive's Tale" has been propagated for decades. Everyone believes it. No one challenges it. Few people have ever make the measurement. A High Power "Calorimetry" Test -- Here is my observation. I took a 432 MHz Stripline Parallel Kilowatt Amplifier and applied 700 watts through a UHF female and a UHF male connector, and then into my antenna feed line. After 10 minutes of 700 watts throughput power the UHF connectors were mildly warm. If I estimate that "mildly warm" represents a dissipation of 3 watts out of 700 watts, that's an estimated insertion loss of 0.019 dB for the pair of connectors. You're about to ask, "how can this be, the internal dimensions are approximately a 35 ohm impedance, it's got to cause a 1.43:1 VSWR?" Well, it doesn't. Very Little Total System VSWR -- The mated UHF connector has an internal connector length of less than 0.9 inches. A free space wavelength at 432 MHz is 27.3 inches. The 0.9 inches represents a phase length of 11.9 degrees. If I plot this up on a Smith Chart (or use the mathematical equivalent) I find the following. A 50 ohm antenna with an 11.9 degree long section of 35 ohm line causes an input impedance of (47.9 -j7) ohms. That's an input VSWR of 1.16:1, which gives a worse case reflected-power-caused transmission loss of 0.024 dB. To me that's insignificant. Now, I'll admit that at 10 GHz, where the wavelength is 1.1 inches, that 0.9 inch electrical length connector would be much harder to tolerate. Power Tolerance -- A Type N connector can tolerate low-duty pulses of over 20 kilowatts without a voltage break down. However, steady state power of more than 1 kW could cause the connector to fail from the RF current overheating the center pin. Most connectors have a very similar failure mechanism when steady state high RF power is applied. The UHF connector has an oversized center pin that can more easily tolerate high steady state RF currents. Moreno said that 30 ohms impedance maximizes the power handling, and the UHF connector has an impedance of about 35 ohms. Each EME'er who is using those expensive type SC connectors on his kW amplifier could probably use UHF connectors for his indoor cable attachments, if he desired to save money. The UHF connector has a larger center pin than an SC connector, it might actually have a larger power tolerance than the SC -- this will require testing. But, remember that the Fluoroloy-H dielectric on the SC connector is designed to be a good heat sync that cools the center pin. It's User Friendly Assembly -- There are probably twice as many amateurs who can do a good job of installing a UHF connector on an RF cable, as compared to a Type N connector. The proper installation and WX proofing of a Type N connector requires considerable finesse and experience. It's almost an art form. UHF Connector Faults -- There are two major faults I can find with a UHF connector when it is being used on 432 and below: (1) the lack of weather proofing; (2) the lack of outer conductor finger contactors. With a proper tape wrapping job, I believe the weather proofing can be accommodated. However, the user must be sure that the internal "teeth" are properly seated, and that the outer nut is kept tight; otherwise the outer conductor can develop a considerable growth in electrical length, with the associated "scratch contacting" noise. For this reason the connector is probably inappropriate for a high vibration environment, unless an auxiliary nut-retaining mechanism is employed. So, maybe it's time we stop saying such bad things about the poor-orphaned UHF connector. For our purposes, it doesn't deserve all that flack. Properly used by a savvy engineer, who understands the idiosyncracies, it can give you a lot of bang for the dollar. It's been around for 60 years, that's no coincidence. I welcome alternate opinions on all of the above. Please feel free to correct the mistakes. 73 es Good VHF/UHF/SHF DX, Dick, k2RIW. Grid: FN30HT84DC27. APPLICATION NOTES: 1. UHF Connector VSWR at 432 MHz A 15 db return loss from a UHF connector that's being used at 432 MHz is quite good in many circumstances. That return loss (a 1.43:1 VSWR) only causes an insertion loss of 0.14 dB (before correction, such as re-tuning the transmitter). On the transmitter side of an EME system, you'll never know it's there. But, if there was a 15 dB return loss caused by a connector that's in front of a well tuned LNA, that is significant. It could make a considerable difference to the system's Noise Figure, if the operator did not apply VSWR corrective action -- such as tuning the LNA for best Noise Figure performance while it is connected to the real system. However, I suspect that very few of the currently operation EME antenna systems have a return loss of better than 15 dB -- particularly not during rain and snow. Therefore, that savvy EME operater has had to apply corrective action to the total antenna system, if he wants full performance of his LNA. If the UHF connector is part of that antenna system, it will get lumped together within that corrective procedure. Thus, that connector 15 dB return loss could be very tolerable to a well-informed operator. 2. More 50 Ohm Magic, UHF Connectors Introduction -- In various responses to my 31 May 2001 treatment of UHF connectors, cogent comments were made that I wish to address, and add to. Connector Brands -- Since the UHF connector doesn't seem to be protected by a MIL Specification, there is a wide variation in the quality and mechanical performance of the connectors that are available on the world wide market. The buyer must be wary. I hope that a savvy amateur will create a web site list that will inform us of the UHF connector brand names, and sources, that are worthy of our hard-earned money. Lloyd, N5GDB, and Lloyd, NE8I both strongly recommend the silver plated or gold plated versions, particularly with respect to solderability and connection integrity. Installation -- I probably was too hasty when I stated that twice as many amateurs/engineers can properly install a UHF connector versus a type N connector. An experienced RF maven (one who has a "feel" for the way RF flows) can almost always suggest an improvement in the connector installation procedure -- so that the lowest VSWR, least loss, best mechanical strength, best longevity, and best weather proofing are realized. Most of my outdoor equipment uses type N connectors, with BNC's most used indoors, and SMA's used within enclosures. For the few UHF connectors that I use, here is my favorite connector installation method. (1) After properly cutting back the braid and dielectric, I next tin the braid (and center conductor) with as little solder as possible, that will still coat the strands. Since the end of the cable is completely open to air at this point, the amount of melting of the polyethylene dielectric is minimized. (2) I slip the nut onto the cable and then screw on the connector body. The tinned braid causes extra resistance, and a strong pair of pliers are definitely required. (3) Assuming that I've chosen a connector brand that readily accepts solder, the process of tack-soldering through the 4 holes requires very little heating time, when using a large-enough, hot-enough, soldering iron. Thus very little further melting of the polyethylene dielectric takes place, and the complete braid is essentially bonded to the connector body. (4) Clean off as much solder from the tip of the iron as possible, and heat up the side of the center pin, while applying solder down the front hole. Try to keep solder off the side of the center pin. If need be, wipe off any excess while it is hot. Excess solder left on the outside of connector center pin will interfere with the proper mating with the female connector. A further benefit of the braid tinning process is that the strands of the braid don't become scattered, spread, and folded back during the process of screwing on the connector body. Thus, full braid strength, and electrical bonding is assured by this process. I suspect that other experts have further improvements on this process, and I welcome their comments. Crimp Connectors -- For indoor, non-critical applications I believe that crimp connectors can be very expedient and handy. However, the crimping process has a number of characteristics that bother me: (A) True UHF Frequency VSWR -- For many crimp connector designs the outer braid is crimped quite far back from the end of the cable. This creates an outer connector choke assembly that makes the outer conductor longer than the center conductor. (B) Salt Spray Survival -- My previous salt mine (the former AIL System Inc., now EDO-Electronic Systems Group) performed a number of salt spray tests a few years ago on crimp-connected semi-rigid cables. The results were not encouraging. In a number of the cables the UHF or SHF VSWR changed considerably after a few cycles of the salt spray exposure. It is hard to beat the RF bonding that a solder joint creates. (C) Ultimate Shielding Requirement -- Arguably, the most critical requirement for an indoor connector is that of the jumper cables on a repeater's duplexing filter. In this application you desire the connector to provide 110 dB of shielding integrity (if you can get it). I personally have experienced repeaters that would develop "scratchy interference" and RCVR desensitization as the type N crimp connected jumpers were manually moved. Lloyd, NE8I also mentioned these problems concerning silver plating. On the two occasions that I experienced this, the problem was cured when the jumpers were replaced with well-installed conventional type N connectors. I have been told of desperate repeater owners who used conventional type N connectors, but modified them by soldering the internal collet assembly to the cable braid before assembling the connector, as a way of avoiding any oxidation-caused scratchy braid connections. (D) Weather Proofing the Crimp -- In a conventional type N connector, the portion that consists of the compression bond of the braid and the internal collet is all contained within the weather-proof portion of the connector. However, in most crimp-type connectors, the crimped portion of the cable's outer conductor is exposed to the weather. This suggests that the crimped joint is subject to corrosion, and a subsequent poor connection. Most of us will tape and shrink-wrap our outdoor type N connectors as a "belt and suspenders" approach to secondary weather proofing. In the case of a crimped connector, our weather proofing of the outer braid is a primary protection requirement. My (Crimp) Conclusion -- If we do a really good job of installing a connector on an outdoor coaxial cable, we are likely to use that cable for 10 to 15 years. A crimp connector is capable of saving you a considerable amount of time during the initial installation. However, if the crimp connector gives you trouble within the first few years of service (that's what the salt spray tests suggest), than the time saving during the installation of a crimp connector might really be a false economy. I'm willing to spend an extra 10 minutes installing a connector, if it is likely to give me over 10 years of service. Here is my challenge. Does anyone know of a well documented set of salt spray tests that were performed on various stiles of RF coaxial cable crimp connectors? A salt spray test is a beautiful way of artificially putting 10 years of aging into a cable assembly within a week. Many of us live within a hundred miles of a sea shore, and this characteristic is important to us. I'll admit that the Microwavers who live in the Mojave Desert may not have this particular problem to worry about. Mismatch -- Leonard, N3NGE spoke of the difficulty of sweeping a cable system that has a high return loss connector at the beginning. Jerry, K0CQ suggested that the problem can be overcome with a Time Domain Reflectometer (TDR), and it will even display the water that is within a section of the cable. I've spent a few years of my life using TDR's and I love'em. They can make RF measurements that will amaze you. However, they are expensive, rare on the surplus market, and few colleges even mention this wonderful instrument. That's unfortunate. A really good TDR will allow you to inspect the integrity of your transmission line system at possibly every 1/8 inch at a time, and it will "look through" that poor connector that's at the beginning of the cable. There are TDR "De-Embedding Techniques" that will allow you to inspect portions of your cable that are surrounded by some pretty significant mismatches. There is a solution for us amateurs, it's called the Steinhelfer Technique. If you sweep the cable, and stop at say 1,024 separate frequencies, and measure the amplitude, and phase of the reflected power, you now have a data set that can do magic. Apply this data set to a computer program that performs a type of Fourier Transform, and it will simulate a TDR that is far above the performance of the one that you could afford. We have all seen those fairly inexpensive hand held VSWR Sweeper-Plotter machines. Add a phase measurement capability, and an RS-232 port to that machine, and you're almost there. That modified hand held device will gather the raw data, and a PC could process the data and make up the TDR plots. A VSWR plotter that sweeps 1 to 1,000 MHz could give you the capability of resolving what's going on in your transmission line system every 6 inches. For most of us, that's good enough to locate a faulty section. Sweep the data gatherer from 1 to 2,000 MHz, and you will resolve every 3 inches, etc. It's about time that somebody offers this as a new RF toy for our pleasure. I'll admit that the Steinhelfer technique involves some fairly heavy mathematics. But, it can be taken in stages, and you could share the responsibility. Just assemble an RF maven, a mathematician, and a Computer Science major, and point them in the right direction. This would make a fantastic Senior Project for a group of engineering students. Later, it might even make them rich. For those who wish to study this further, see the following references: (1) HP Application Note 62, "Time Domain Reflectometry", 1964.

You'll be amazed by the results. The K3 works well with just about any mic. Well done Elecraft. I never bought any handmic. But I own several headsets, a $4,50 plastic one (has a good mic), a Yamaha CM500 ($45, many K3 owners have that one, good mic) and a david clark aviation headset (several hundreds of dollars, good mic). The difference is in the ears of the headsets, all mics perform well, thanks to the EQ/gain/proc-setting possibilities in the K3. I take the plastic headset with me when camping, the CM500 in my quiet shack and the david clark when I'm working in a multi-operator contest with lots op people walking and talking. As far as mic-audio is concerned: how much hi-fi can you put through a 2.5kHz bandwidth SSB signal? Will the expensive Heil PR-10 make a real difference? For peace of mind: buy the Heil. 'My mic is is Heil PR-10' sounds quite different from "my mic is a cheap electret computermic'. :-) 73 Arie PA3A Op 13-10-2016 om 20:37 schreef Bill DeVore: > I just completed assembly of my K3S, KAT500, KPA500 and P3.

You are getting results very, very different than I do. What bands are you using? On each band in question, what is the noise floor on the s-meter when the band is open. On each band in question, what is the s-meter reading for the loudest signals you are receiving when the band is open. On each band in question, what are these settings made from the front panel: PRE, ATT, AGC, ANT, RX ANT, WIDTH, What are these settings made in the CONFIG MENU: AGC DCY, AGC HLD, AGC PLS, AGC SLP, AGC THR, AGC-F, AGC-S There is some kind of interaction with NB and NR for each of these. Perhaps there are one or two of them that are reducing your results. 73, Guy K2AV From jim at audiosystemsgroup.com Thu Oct 13 16:01:50 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 13 Oct 2016 13:01:50 -0700 Subject: [Elecraft] Microphone In-Reply-To: <38aa41f7-2100-1443-6238-d3531bcb98c7@xs4all.nl> References: <38aa41f7-2100-1443-6238-d3531bcb98c7@xs4all.nl> Message-ID: The CM500 is the clear winner -- great sounding mic, great sounding headphones are very comfortable.

The resistor is used to limit current draw when pin-7 is grounded (inhibiting Tx). With pin-10 directly connected to pin-7, pin-7 will go directly to low when pin-10 does. If you want a little more insurance that current goes the correct direction add a diode pointing toward pin-10 from pin-7.

I am concerned about the transmit IMD results mentioned only in a side bar "Lab Notes: ..." on page 50. Initially the transmit IMD in the original review sample was less than stellar, but eventually got resolved by Elecraft submitting a new review sample with KPA3A rev C4 and KLPA3 rev B installed. How can I tell if my relatively new K3S ser# 10480 has the new modules installed? If they aren't, is this a warranty repair?

On the air, these mics are indistinguishable from much cheaper units, if everything's adjusted properly. A ham who spends more than $75 on a mic because he feels he needs to to sound good is misinformed. However, one factor at play here may be the pride of sitting behind a big name mic as you transmit. I'm not going to take that away from any ham who wants that experience. Just don't claim that it makes you *sound* any better. It doesn't. R, Al? W6LX ???

While a thorough analysis of "To Preamp or Not to Preamp" is complex and very situational, the antenna check is really a very good indicator: Remove the antenna and note the noise produced by the K3. Connect the antenna. If the noise rises, adding a preamp at the radio isn't likely to do much for you. At the antenna, it can compensate for loss in the transmission line, but that's not likely very high on 10m or even 6m unless your coax is very long or full of water. My experience is: When the noise rises by connecting the antenna and I still can't hear the signals, I need a better antenna.

WRONG -- virtually all modern PA and sound reinforcement systems have used 3-pin XL connectors for more than 50 years. The exceptions are VERY CHEAP junk sold by places like Radio Shack, and those built into security systems. Most musical instrument amps have only unbalanced inputs. Back in the '70s, I was maintaining lots of paging systems professionally installed paging systems that used balanced mics and balanced wiring exclusively, and many of them had been in service for 20 years. I don't remember ever working on a PA system that used unbalanced mics except as lavalier mics connected to a wireless mic transmitter. Communications mics made by companies like Shure, EV, and Turner were/are made with output transformers that matched them to balanced low-Z inputs for use in professional systems and unbalanced hi-Z for use with ham radio, and PTT switches that can either be wired to key a transmitter or short/open the audio path. The Shure 444 is a great example -- the response is carefully tailored to roll off the low end and add a strong peak around 3 kHz to compensate the rolloff of the TX SSB filter. This response also works well for paging. 73, Jim K9YC From ab2tc at arrl.net Thu Oct 13 21:24:10 2016 From: ab2tc at arrl.net (ab2tc) Date: Thu, 13 Oct 2016 18:24:10 -0700 (MST) Subject: [Elecraft] Microphone In-Reply-To: <882c3082-a9f6-509b-541d-6f0bc1c47a3b@audiosystemsgroup.com> References: <38aa41f7-2100-1443-6238-d3531bcb98c7@xs4all.nl> <882c3082-a9f6-509b-541d-6f0bc1c47a3b@audiosystemsgroup.com> Message-ID: <1476408250435-7623336.post@n2.nabble.com> Hi Jim, Gee Jim, I don't quite understand what your point is. You and I have always been agreeing that the use of professional audio microphones and other equipment for communications is not only a huge waste of money but also a big inconvenience; 3-pin XL is not a convenient connector for ham radio use. Who cares what PA and sound enforcement equipment equipment is using for a microphone connector.

That is *IF* you are using DATA A submode where the TX and RX equalization is set to flat and the compression is turned off. If you are trying to use SSB mode, you can follow the "internet advice", but the using the Elecraft gear, you should follow the Elecraft manual - it behaves differently than most transceivers and has special provisions for data modes that are absent in other transceivers. The Fldigi manual is written for the 'other' transceivers because they are more plentiful. 73, Don W3FPR On 10/13/2016 9:33 PM, Thorpe, Jeffrey wrote: > I'm going though the FLDigi manual and have come across (at the "Operating Controls and Displays" section, regarding the QSY button) a reference to the 'sweet spot' and setting parameters for it in the configuration screen.

It was determined to be the optimum peak response for communications. For example, the famous D-104 with its original crystal element from the early 1930's featured just that peak. As others mentioned, any electret element sold today has a frequency response far better than any communications circuit can use. For example, I have a $4.00 Radio Shack electret element that is flat from 70 Hz to over 10 kHz. Of course, any decent SSB rig will limit the audio bandwidth to between 300 Hz and about 2.7 kHz. If you are really serious about getting the boost around 3 kHz an Elecraft K3, K3S or KX3 can have the Tx equalizer set up to provide that for you. 73, Ron AC7AC From jim at audiosystemsgroup.com Thu Oct 13 23:24:04 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 13 Oct 2016 20:24:04 -0700 Subject: [Elecraft] Microphone In-Reply-To: References: <38aa41f7-2100-1443-6238-d3531bcb98c7@xs4all.nl> Message-ID: <36da6c5d-c7d1-be14-b59d-a3489cf9a117@audiosystemsgroup.com> On Thu,10/13/2016 1:18 PM, Michael Wong wrote: > I?m still more of an audio professional than an accomplished ham, so I?ll ask while the thread is hot - why does ham gear use non-standard interconnects?

Not much. But there's more to microphone quality than frequency response. 1. Plosives. Will the mic handle poppy 'p' sounds without overloading? 2. Directionality. Is it directional? If not, you'll get more shack reverberation, fan noise and reflections from the desk (causing comb filter notches in the response). 3. Proximity effect. Will the mic increase LF as you get closer to it? If it's directional, yes it will, unless it's one of the Electro-Voice Variable-D types or similar. Omnis don't have proximity effect. 4. Handling noise. If hand-held, how much unwanted noise is generated as you move around? 5. Screening. Is it adequately screened? If not, it may be more prone to RF feedback. 73, Richard G4DYA From w2blc at nycap.rr.com Fri Oct 14 08:20:37 2016 From: w2blc at nycap.rr.com (Bill) Date: Fri, 14 Oct 2016 08:20:37 -0400 Subject: [Elecraft] Microphone In-Reply-To: <52fb3cd2-795b-db6c-0fb9-edc2b95c653a@lamont.me.uk> References: <52fb3cd2-795b-db6c-0fb9-edc2b95c653a@lamont.me.uk> Message-ID: <80aa6165-e65d-2377-6fea-a86dd76ceee9@nycap.rr.com> The point is: Using most any mic - from $10.99 to $500.00 - because it is all in the way you set up the K3(S).

I recommend you increase the AGC THR setting and decrease the AGC SLP. Look at my website www.w3fpr.com "Noisy K3" article. It will give you guidelines for setting those AGC parameters to best deal with the ambient noise you have at your location. Pay particular attention to the method of evaluating your changes. You must listen during pauses in a signal. If you listen only to the noise, you will end up adjusting the wrong direction. 73, Don W3FPR On 10/13/2016 3:58 PM, glcazzola at alice.it wrote: > > in the CONFIG MENU I have: > AGC DCY - nor > AGC HLD - 0.00 > AGC PLS - nor > AGC SLP - 012 > AGC THR - 005 > AGC-F - 120 > AGC-S - 020 > > From alsopb at comcast.net Fri Oct 14 09:53:56 2016 From: alsopb at comcast.net (brian) Date: Fri, 14 Oct 2016 13:53:56 +0000 Subject: [Elecraft] Is the K3 have low sensitivity on 10 M and 6 M In-Reply-To: <78e80614-b7c4-4ca4-64af-e29995ea7386@foothill.net> References: <1476319571408-7623290.post@n2.nabble.com> <1476362797084-7623306.post@n2.nabble.com> <78e80614-b7c4-4ca4-64af-e29995ea7386@foothill.net> Message-ID: <5800E374.3030506@comcast.net> This test may be a bit out of date.

(Nice website too.) One little point I would add to comments about listening to whether you hear band noise when connecting that antenna, is that if you're performing this test at VHF, or even the high end of the HF, the actual connection/disconnection of the antenna should be from the back panel of the radio, not via an antenna switch with some undetermined length of coax. What can happen is that sometimes simply connecting an open length of coax to the antenna input may change the audible noise coming from the receiver's speaker. I haven't tried this with my K3s, but I've observed this effect with other * radios, especially ones which depend on good input impedance matching for their antenna inputs. This effect is related to the length of the coax relative to the frequency you're listening to, so I doubt if it would be noticeable below, say 10 or 15 M with a few feet of line to an antenna switch. 73, Charlie k3ICH *I specialize in the restoration of the Collins 51S-1 receivers, and have noticed this effect with them. The 51S-1's sensitivity is quite susceptible to degrading from an unmatched antenna. During an alignment, I see a small, but noticeable difference in the antenna input coil adjustments from using a matched 50 ? signal generator versus leaving the antenna input open and relying on the calibrator signal for peaking.

One of the first problems I encountered with my new K3s/10 was poor Tx IMD performance. What I observed was flat topping that started at about 5W, and progressively got worse as the power was increased. The distortion was so bad at 10W, the envelope looked more like a squarewave than a two tone signal, and the 3rd order products were down only -18 dBc. After several months of working with Wayne, Rene, and the designer of the KLPA3A amplifier, replacing the KLPA3A three times, and sending the radio to the factory, the problem was reduced, but I still don't see better than -28 dBc at 10W out. Not wanting to send the radio in to the factory a second time, I decided to just live with the performance. The transmit signal generation in the K3s is a complex process based around the internal computer. Signal quality is affected by ALC, transmit power level, configuration settings, and the transmit power CAL, however, from all of the testing that I did, the signal going into the KLPA3A was very clean (-40 dBc). It is also important to note that Elecraft's approach to distortion management includes spreading the energy in the distortion out spectrally by the use of pre-distortion. This results in 5th, 7th, 9th,... order products being higher compared to some radios, as noted in the QST article. The QST article indicated that both the KLPA3A and the KPA3A have been modified to address the Tx IMD problem.

During the course of my troubleshooting, I noticed that a number of changes were made to the original KLPA3 in the process of getting to the new KLPA3A design.

Normally, the K3S (or K3) has worst-case TX 3rd-order IMD in the vicinity of -30 dBc (ARRL method) at rated power (10 W/100 W +/- 1 dB on most bands; see specs for exceptions). Nearly all other 12-V-capable transceivers are in this same range, because they all use approximately the same circuitry and PA devices. We have made changes in K3S production that improve average IMD performance at both low and high power levels by as much as 3 dB. We will make these changes free of charge on any K3S returned to the factory for this purpose, whether or not it is still in the warranty period. The only charge would be for return shipping. The changes were phased in at the following serial numbers: KPA3A (100 W PA option): Factory assembled, #10852 Kit, #10864 LPA (10 W module): Factory assembled, #10920 Kit, #10939 Please email k3support at elecraft.com if you have any further questions. 73, Wayne N6KR From n1rj at roadrunner.com Fri Oct 14 17:27:35 2016 From: n1rj at roadrunner.com (Roger D Johnson) Date: Fri, 14 Oct 2016 17:27:35 -0400 Subject: [Elecraft] Fwd: NaP3 version 5 In-Reply-To: <5801151A.1060701@roadrunner.com> References: <5801151A.1060701@roadrunner.com> Message-ID: <58014DC7.2010106@roadrunner.com> From n7xy at n7xy.net Fri Oct 14 18:46:27 2016 From: n7xy at n7xy.net (Bob Nielsen) Date: Fri, 14 Oct 2016 15:46:27 -0700 Subject: [Elecraft] e: Windows Emulator In-Reply-To: <805F933B-1084-419D-AA5B-C11261E25DDB@gmail.com> References: <805F933B-1084-419D-AA5B-C11261E25DDB@gmail.com> Message-ID: <56318a33-b3e0-a845-b7ed-4c7044372c15@n7xy.net> There is a WSPR-X app for the Mac.

Yes, you must provide a connection that grounds the PA KEY connection to the KXPA100. I do not know of a commercial cable that will provide KEYOUT from the Flex to the KXPA100. If you are not able to build the cable yourself due to whatever problems, perhaps you can find a local ham who would be willing to assist you with the soldering and cable construction. Look for a ham who has been licensed for many years (likely has a 1X3 call). We used to build our own gear and questions like this rarely came up. We were all expected to be able to do soldering and follow a schematic by our peers. Sadly, those days seem to be no longer the norm. 73, Don W3FPR On 10/14/2016 6:58 PM, Jose Rivera wrote: > I am a happy KX3, KXPA100 owner. I had the opportunity to obtain a Flex-1500 radio.

The one compromise I ended up making was not getting the aluminum up a full half wave in the air. Fully half the directionality is down a steep hill, so electrically it meets that criteria. However the other half is back into the hillside so in that direction not so much. It has still been a very worthwhile pursuit. This antenna beats my 80m @ .5 wave doublet multiband antenna.

I purchased the K3/10 in 2010 which is able to output up to 12w. Is the low power amp any better at IMD, or subject to the same limitations because its 12v transistors? I bought the KXPA-100 last year. Would it be any better than the KPA3 or KPA3A? 3rd-order IMD in the vicinity of -30 dBc is about what I have read for specs my many 12v power devices. I bought the new synth because I understood it would improve Rx performance (haven't installed them yet main & sub Rx). Also for K3 use at 630m. Would running the K3/10 at 5w driving a linear amp be lower in IMD? The amp uses 50v devices and made for TV which has greater linearity specs than SSB. I am also running it at about 60% full output on 6m. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From wes_n7ws at triconet.org Sat Oct 15 00:30:31 2016 From: wes_n7ws at triconet.org (Wes Stewart) Date: Fri, 14 Oct 2016 21:30:31 -0700 Subject: [Elecraft] K3S QST Article In-Reply-To: References: <20FD02D5-41BF-4459-82CB-75B04BB0BC4C@law.du.edu> <1476393931254-76 23325.post@n2.nabble.com> <1476461161413-7623355.post@n2.nabble.com> <147 6470017722-7623363.post@n2.nabble.com> <6f6fcc4a-45d4-10f8-7c5e-d9a50aab1049@ac0h.net> Message-ID: <1a951c8e-1e64-a589-4449-1de3f56f3f9a@triconet.org> Without too much elaboration let's just say that I discovered this problem long before ARRL did. (S/N 10020) I can tell you that my measurements show that IMD varies with Vcc (Vdd), drive level, power output and frequency. This latter parameter is, as best as I can determine, inexplicable by anyone, including the manufacturers of the transistors. Initially, I compared my shiny new K3S to my tired old, unmodified K3. At the original test frequency, 3.8 MHz the K3 had much lower IMD that the K3S under otherwise the same test conditions. Moving up to 14 MHz the situation reversed. Each of these radios had a different "sweet spot," neither of which was representative of the general case. If a testing entity happens to test at only one frequency and reports the results as typical then you get a false sense of the general performance.

Do NOT plug a standard serial cable into the AUX IO connector, that can damage both the K2 and the serial port. First, check to see if the PORT menu setting is ON. That is in the secondary menu (enter the menu and tap display to get to the secondary menu). Do you have sidetone on that K2? If not, go to the STL menu setting, Edit the parameter and tap DISPLAY until you hear sidetone. Then test again. Do you have 12 volts on pin 8 of the DE9 connector? If not, inductor L1 on the AUX board may be open. On the KIO2 board, check inductors L2, L3 and L4 for continuity. Those are quick checks. If you continue to have problems, it is likely to be the MAX1406 IC on the KIO2 that is the problem. If you are willing to disconnect a wire in the internal cable to the KIO2 board, I can give you some DC tests to check that IC. 73, Don W3FPR On 10/14/2016 11:40 PM, Brad Brooks wrote: > While I continue to review the list archives, I am requesting feedback from the group with regard to possible failure modes of the KIO2 board.

It provides many of the fundamental configuration details that apply if you're using a KX3 or KX2 as well. If you havent' done so, my suggestion is that you get PSK31 set up and running first then move on to WSPR or one of the other JT65 programs. FLdigi is a popular and low-cost (free!) way to get started that way. Do post here about what rig you're using and any additional soundcard devices you may intend to use. These details make a difference how the set up should work.

That's what I do, and it works perfectly. No additional hardware needed with the K3S, just the USB interface from the radio to the PC. Only thing to watch out for is to make sure Commander is set to "DATA-U" mode so the audio generated by your PC will be ported to the DATA input on the radio. That has gotten me a few times. Give me a call some time if you need more info. 73, Ken, KJ9B -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Steven Stuckey Sent: Saturday, October 15, 2016 9:34 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] JT-65 I looked in the owners manual and did a search for JT-65 and nothing was found.

Regarding the Yaesu radio that hit -38 dBc worst-case using the same PA topology: luck of the draw. There are many factors, including things as esoteric as the quality of the ferrite in the output transformers. We've measured similar rigs from all major manufacturers that were right around -30. In addition, many radios will not hit 100 W on all bands, even at 14 V. 73, Wayne N6KR On Oct 14, 2016, at 9:30 PM, Wes Stewart wrote: > Without too much elaboration let's just say that I discovered this problem long before ARRL did.

In a K3(S)/100 the HPA isn't activated until above 12W. IMHO, again based only on my measurements of my K3 and my K3S (before mods), I would recommend that Elecraft change firmware to set the max power out at 10W (LP) and switch in the KPA100 above 10W, not 12.

These days everyone uses MOSFETs, which are consistently in the -30 dBc range on at least one band. The K3S with the latest updates averages about -35 dBc at 100 W (see ARRL review).

Being tied to mains power would impact my club's use of K3s with batteries on events like the California QSO party. (Our location does not permit generators.) I don't know how much such a restriction would shrink the K3S market. A voltage booster could be a solution. Such a device would have to be well shielded and bypassed to avoid RFI. It could either be internal to the radio or a "bump on the power cable". Such devices are available in the market and seem to work well. 73 Bill AE6JV On 10/14/16 at 5:14 PM, kstover at ac0h.net (Kevin) wrote: >The cause for this is the use of 12V finals.

Offhand I don't have mine handy, but I was pretty amazed at how quickly the IMD rose above 10W. I'm not saying anything new here, back in December in this thread http://elecraft.365791.n2.nabble.com/Powering-a-K3s-from-a-battery-tt7611959.html#a7611980, I said among other things: "All I'm saying is that if you run the LPA at 10-12 watts, according to my measurements*, the IMD is pretty bad. If you have an HPA, then after it's kicked in, (13W in my K3S) the LPA is running at greatly reduced power. I don't believe Elecraft has to change anything. Guys with a KPA3(A) just need to avoid the grey area of 10-15W. *Remarkably, IMD measurements I made on my K3S using modest equipment correlated within 1dB or less to measurements made by Elecraft, on the same radio.

It provides many of the fundamental configuration details that apply if you're using a KX3 or KX2 as well.

FLdigi is a popular and low-cost (free!) way to get started that way. Do post here about what rig you're using and any additional soundcard devices you may intend to use.

Being tied to mains power would impact my club's use of K3s with batteries on events like the California QSO party. (Our location does not permit generators.) I don't know how much such a restriction would shrink the K3S market. A voltage booster could be a solution. Such a device would have to be well shielded and bypassed to avoid RFI. It could either be internal to the radio or a "bump on the power cable". Such devices are available in the market and seem to work well. 73 Bill AE6JV On 10/14/16 at 5:14 PM, kstover at ac0h.net (Kevin) wrote: >The cause for this is the use of 12V finals.

The ARRL publishes a "typical" IMD figure and a "worst case" figure which I assume to be the worst case for any band and they they publish which band this is (12m for the recent K3S review). Anyway, this doesn't change the fact that about 600 K3S purchasers are faced with the prospect of having to face the cost and inconvenience of having to return their rigs (I am one of them) to fix this apparent design flaw. Not to do so would be unethical (to transmit with excessive IMD). AB2TC - Knut Kevin wrote > Yaesu's secret was the ARRL.

Those of us involved in those exchanges were clear when Wayne "suggested" that we use K3S (capital S) for the new radio when posting here to avoid confusion. The problem exists because, for marketing and registration issues, Elecraft elected to use a *smaller font capital S for the S in K3S*. If you think about it, you will notice that we have no choice of a font selection here on this reflector for a smaller capital S. So, the obvious fix for here was to use K3S (capital S) for the new radio. I think Wayne tried to explain that back then and some new users just don't understand why, and consequently, attempt to mimic the artistic expression of the new radio graphic logo. If you look closely at the Elecraft web site you will see that much of the new literature and reference to the K3S on the site has begun to evolve into the K3S (capital S) probably for the sake of clarity.. Wayne may jump in to clarify, but that's what I recall.

My operations are different! The reason for entering this discussion is that the battery is being mentioned which I am more than pleased with for CW at 5 Watts. I have some observations and a question to finish with. First the battery pack appears to weigh approximately half that of the KX3 battery pack and is physically half size. I am most pleased at the rapid charging time of about three hours versus up to sixteen hours for the KX3 battery pack. From now on I will take the charger with me on trips - it works from a wide range of line voltages. Different computer line power cords for the UK, Europe and USA are easily obtained. One battery pack should do. You can not run the KX2 from the Charger!!! The charger is light and small with the line cord being an unfortunate necessity. Owning both a KX3 and KX2 my intent is in future to only use the KX2 battery pack with either radio. Travelling by plane with KX3 may be a problem in that the battery pack should be inside the radio. The KX3 will not be flying besides the KX2 is half the volume and weight. Normally the battery pack is kept external to the radio. Now this is not a comparison of like loads but I find that the KX2 battery pack will last nearly two pages of CW QSOs. The life span of batteries with the KX2 beats the life span of batteries with KX3 - this is not a numerical judgement but one observed through operation. Does anyone in the UK or the greater EU have a source of the KX2 type battery pack in Europe other than those sold by a UK official supplier? I want to continue using the KX2 charger. Adding a connector is no problem. Another KX2 KX3 topic: I find the KX2 an amazing wee radio. My KX1 has gone to a new home where it will be used on the trail. I miss 160M and would probably like 6M but to be honest TB is not used while travelling and the magic band QSO style I find boring in Europe - no one rag chews. Hopefully Bob Sherwood will do a review of receiver performance. The KX2 can not(?) match the KX3 but it is everything I require for portable operations. Maybe the KX2 underperforms the KX3 for QRP contesting or for a DXpedition with large pileups. It would be nice to know the RX figures. It was love at first sight when the KX2 viewed at Friedrichshafen. This is a fun radio for someone interested in portable and especially tail work. Alas it is portable operations here. 73 Doug EI2CN KX2 SN 1000 Yes this is correct -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Howard Sherer Sent: 16 October 2016 12:31 To: elecraft Subject: [Elecraft] Performance of the KX2 batt I have been running my KX2 with the Elecraft supplied batt pack for the past two weeks and have a question for others using the same.

At lower voltages, the KX2 IMD goes up, so the firmware reduces power output to maintain a clean signal. The choices seem to be: Keep going with 5W and enjoy QRP. Pack up the radio, go home, and enjoy a beverage of your choice. Use an external battery pack. Other chemistries, like NiCd and NiMH, tend to hold their output voltage longer into the discharge cycle. They might be a better, although heavier, choice for an external battery pack. 73 Bill AE6JV On 10/16/16 at 5:31 AM, hms4 at lehigh.edu (Howard Sherer) wrote: >I have been running my KX2 with the Elecraft supplied batt pack for the >past two weeks and have a question for others using the same.

I have a 400kz filter as my narrowest CW filter and tune like this: ??? 1) Zero beat exactly ??? 2) Hold the XFIL/APF button??? 3) Narrow the width as far as it will go? to .05 which I interpret as being 50hz??? 4) it might help to change tuning to 3 digits by taping the FINE button??? 5) Tune ever so carefully +/- a few hz and sometimes shifting slightly until the best signal is heard A weak signal often pops right out of the noise, but be you will find there may be unpleasantringing, popping in the noise you might not like.? Point is u can pull a signal out and work himwhen it would otherwise be impossible to copy. 73Dave N4DB?

I had fits trying to use APF with 200-400 Hz dialed in until I launched Spectrogram and made sure the signal peak aligned with the APF peak. Weak signals still show even when you have trouble hearing them.? This alignment helps with pulling them out.? One can tune either the K3 shift knob or K3 main tuning if it is set at 1 Hz steps. Works every time. Spectrogram can be collapsed to a small rectangle for this purpose an permanently left on the display.? HSDR also has a narrow bandwidth display. Other spectrum display programs would work as well. 73 de Brian/K3KO On 10/16/2016 13:03 PM, Chip Stratton wrote: > I seem to recall a recommendation to use a 400 Hz bandwidth with APF. > In my own exerience, narrowing DSP bandwidth much below this does not > seem to help APF function and rather muddies it. > > Chip > AE5KA > > On Sat, Oct 15, 2016 at 11:44 PM, Brian Hunt > wrote: > >> On the other hand, when used in conjunction with NR a wider DSP BW is >> desirable since NR works on uncorrelated noise.

The laws of physics dictate that uniformity of high frequency response is limited by diaphragm size -- the larger the speaker, the worse it sounds off axis. The speaker built into the K3 is a nice small one, so it has pretty good off axis response, but it faces straight up. In most shacks, the highs bounce off of nearby surfaces to get to the listener. A front-facing loudspeaker will have flatter response, but takes up more space on the operating desk. 73, Jim K9YC On Sun,10/16/2016 3:02 PM, MaverickNH wrote: > So what's the verdict, High-Fidelity or HAM-Fidelity?

While it is true that there is not normally much response above 4000Hz from a ham transceiver, the speaker should not be the limiting factor. IMHO, the best characteristic of a speaker is the flatness of its response curve rather than its frequency range. A speaker with a flat response will allow you to hear the transceiver "as it should be" without distortion. So my vote is for "High-Fidelity" speakers. 73, Don W3FPR On 10/16/2016 6:02 PM, MaverickNH wrote: > So aside from speakers that match the design of a transceiver, there seems to > be some difference in philosophy about frequency range.

I'm pretty sure it isn't also saved per mode. I've never been at ease with memory functions that simply save the last state without leaving a message somewhere on the display what the current saved state is. When the "Power for KPA state" feature came out, there were several times when I faulted the KPA on the first dit because the power was at 100W. I know it was pilot error but I began to check it just to be sure. For a remote station with multiple operators in various places on the planet, I really do *always* check the power settings before transmitting. 73, Fred K6DGW - Sparks NV DM09dn - Northern California Contest Club - CU in the Cal QSO Party 7-8 Oct 2017 - www.cqp.org On 10/16/2016 3:38 PM, George Kidder wrote: > I suspect that most of us like to reduce our power output on digital > modes, so the continuous carrier doesn't overheat something.

While I agree that the speakers should not color the transceiver, excessive low frequency response on receive is as wasteful as excessive low frequency response on transmit. In that regard, I'm very happy with a pair of Pyle PCB3 (3" Mini Cube Bookshelf Speakers) - one left and one right. They are specified for 90 Hz - 18 KHz and I *still* use the maximum RX EQ cut on the 50 and 100 Hz bands. Speaker response above 5 - 6 KHz is moot since the K3/K3S includes a 4.5 KHz "brick wall" lowpass filter in the headphone/speaker channel. 73, ...

In the late 50's, in college and on a limited budget, it was common for students to use 5 or 6" speakers in tight cubic boxes made of 3/4" plywood and stuffed with some wall insulation for the then-new stereo records. They sounded pretty good and doubled as supports for the ubiquitous cinder-block shelving. My roomie and I painted ours black.

One way to get excellent performance from 300 to 3000 Hertz is to have very good performance from 30 to 30,000 Hertz. Or something like that.

It's dramatic! Back in the K2 days, many hams folded some stiff card or paper to make such a deflector to tape to the top of their rigs.

What matters is smooth (flat) response from about 200 Hz to about 3 kHz as heard at the ear of the operator. The laws of physics dictate that uniformity of high frequency response is limited by diaphragm size -- the larger the speaker, the worse it sounds off axis. The speaker built into the K3 is a nice small one, so it has pretty good off axis response, but it faces straight up. In most shacks, the highs bounce off of nearby surfaces to get to the listener. A front-facing loudspeaker will have flatter response, but takes up more space on the operating desk. 73, Jim K9YC On Sun,10/16/2016 3:02 PM, MaverickNH wrote: > So what's the verdict, High-Fidelity or HAM-Fidelity? ______________________________________________________________ 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 ron at elecraft.com From donwilh at embarqmail.com Sun Oct 16 23:32:46 2016 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 16 Oct 2016 23:32:46 -0400 Subject: [Elecraft] Speakers - Optimal Frequency Range?

I don't think that applies today for receivers have adequate selectivity to do that filtering job. Some low end receivers that do not provide adequate filtering may benefit from a peaked speaker, but that is not true of any of the Elecraft receivers. Besides, unless your "filtering" speaker matches the filtering provided by your headphones, there will be a vast difference when switching between the speaker and the 'phones. In modern days, a flat speaker response in the 300 to 3000 Hz range is the best for communications. If the speaker response is greater than that range, it will not matter because the receiver will not produce audio much beyond that 300 to 3000 Hz range. To me, the goal is a flat speaker response in the range that the receiver produces audio. The fact that the speaker is also flat beyond that range is of no consequence unless that same speaker is also used for Hi-Fi listening. 73, Don W3FPR On 10/16/2016 8:17 PM, Dave Cole wrote: > On Sun, 2016-10-16 at 18:28 -0400, Don Wilhelm wrote: >> Bret, >> >> In my opinion, a speaker should not "color" the audio response of the >> receiver. > > Au contraire, the speaker is as much a part of the radio as the > synthesizer, or the APF is.

Several years ago I debated buying a home theater system with prof. speakers as I wondered if I could discern the improvement. I found that having very linear response from 50-Hz to 20KHz improved understanding of voice on the TV as well as enjoyable music. Later, I found choosing the flat response program in my hearing aids also provided the crispest voices and better understanding. Long ago I bought a pair of Sony stereo headsets for listening to weak signals on ham radio. Appears that also was a good move. So even if the audio output is restricted to 300-4000 Hz the speaker reproduces that faithfully. My new blue-tooth capable hearing aids have much wider freq response as I am hearing a wider range from low to high freq. The plus is my iphone connects directly to my hearing aids for best hearing in public (and that half is private). I have yet to try using bluetooth with my K3. Let you know how that sounds, later. 73, Ed - KL7UW PS: my KX3 audio will be connected to the truck speakers via sync; more on that, later.

While it is true that there is not normally much response above 4000Hz from a ham transceiver, the speaker should not be the limiting factor. IMHO, the best characteristic of a speaker is the flatness of its response curve rather than its frequency range. A speaker with a flat response will allow you to hear the transceiver "as it should be" without distortion. So my vote is for "High-Fidelity" speakers. 73, Don W3FPR 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From dave at nk7z.net Mon Oct 17 01:44:54 2016 From: dave at nk7z.net (Dave Cole) Date: Sun, 16 Oct 2016 22:44:54 -0700 Subject: [Elecraft] Speakers - Optimal Frequency Range?

You are assuming that receivers are all 300-3000, they are not, else ESSB would never have come about. ?We are not running broadcast stations, we are running communications links. Best communications is achieved using something close to 300-3000. ?See: http://www.w0btu.com/ssb_audio-weak_signal.html In reality, it really would not matter if one put a high end stereo speaker on the radio, assuming the radio were limited to 300-3000, (as it should be), save a bit of amp noise leaking through... ? So, as I said in my original post, it is the most efficient use of the hardware is to use a limited response speaker. ?No need for high end stereo speakers on a K3... ?That said, I may put on some better speakers on my K3 because in the long run it is a bit less stressful on my ears... ?:) ? -- 73's, and thanks, Dave (NK7Z) For software/hardware reviews see: http://www.nk7z.net From jim at vistasierra.com Mon Oct 17 01:50:23 2016 From: jim at vistasierra.com (Jim Stockwell) Date: Sun, 16 Oct 2016 22:50:23 -0700 Subject: [Elecraft] Sold - K3-100 Message-ID: <000601d2283a$5ae6b910$10b42b30$@vistasierra.com> The K3-100 has been sold.

COARSE (10 Hz) VFO steps is usually close enough but you can switch to FINE (1 Hz) if necessary for ultra weak signals. I also strongly endorse N6KR's suggestion below: "I suggest setting the passband width to about 250-300 Hz when using APF." This is extremely important since bandwidths too narrow will introduce additional ringing to the APF which already borders on ringing. I actually use a 200 Hz XFIL but set to actuate at DSP 400 Hz. With WIDTH set to 400 Hz, the signal first goes through the relatively broad (4.0 shape factor) 200 Hz XFIL, then a 400 Hz DSP and finally the narrow APF. This makes the cascaded XFIL/DSP seem more like 250 Hz, reduces ringing, still allows you to hear off-frequency callers (although attenuated) and helps your ears discriminate weak signals from noise by providing a wider background sample of noise. ####################################################### The last phrase "helps your ears discriminate weak signals from noise by providing a wider background sample of noise" is key. Narrower bandwidths are not best for the human ear/brain...no matter what theory says about narrower bandwidths having better S/N. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-APF-and-selected-bandwidth-tp7623407p7623455.html Sent from the Elecraft mailing list archive at Nabble.com.

But let's look at the physics of loudspeakers, which I tried to do on an earlier post. A SMALL diaphragm has better dispersion of high frequencies, while it doesn't produce loud bass. We don't need loud bass, so a GOOD small diaphragm loudspeaker is what we need. And that is EXACTLY what Elecraft uses in the K2 and both versions of the K3. The late Dick Heyser famously said that "trying to describe an audio device or system using only frequency response is like trying to write Shakespeare with only one word in your vocabulary. In addition, to have any meaning, a frequency response spec must include +/- dB limits and it must include angular dispersion. VERY few consumer loudspeakers do that -- they simply quote upper and lower limits. Many cheap loudspeakers (and headphones) have very bumpy frequency response, and those bumps create phase distortion that degrades speech intelligibility. So, to repeat my earlier advice, the best loudspeaker for ham radio is one that has smooth response from about 300 Hz to about 3 kHz and has wide, uniform dispersion within those limits. In other words, it sounds the same both on and off axis. Loudspeakers that cover a wider frequency range are FINE, but don't pay extra to get one. A loudspeaker with wider response would reproduce lower lows and higher highs, but our ham rigs (at least the good ones when well adjusted) limit audio to a range of about 300 - 3,000 Hz in the IF. There is no good reason to buy a speaker rated for 300 - 3,000 Hz. What we want is one with good performance within that range, and most that do will have at least another octave or two above and below those limits. (An octave is 2:1 frequency) BTW -- I purposely set my RXEQ flat because I primarily work CW, and I want to hear the off-frequency signals that may be very low or very high in frequency, and I limit frequency response on SSB with the settings of my IF filters. 73, Jim K9YC On Sun,10/16/2016 10:44 PM, Dave Cole wrote: > So, as I said in my original post, it is the most efficient use of the > hardware is to use a limited response speaker.

See Wayne's post yesterday. They improved the Transmit IMD for the current K3S and are offering to make that change to older K3S. They are going out of their way to add the change to your K3S free of labor charge - all you have to pay for is the shipping. I think that is above and beyond the call of duty. I have not heard of another ham manufacturer that would do anything like that. 73, Don W3FPR On 10/17/2016 4:41 PM, Jim Rogers wrote: > Elecraft has sold me a radio specifying it to be in compliance with > specifications of IMD.

SVGA Monitor Height = Main P3 = 30 When ever I turn on the P3 (and monitor), I need to reset the Waterfall Height. The Height is fine on the P3, but takes up 3/4 of the screen on the external monitor. The P3 remembers the original Height setting. To reset the Waterfall Height on the external monitor, I need to go to the P3 Waterfall Height, make any change in the Height value, and then the Waterfall Height on the external monitor corrects itself.

VW purposely faked the test to meet a gov't spec. However, Elecraft sold a radio that DID meet their published specifications for transmit IMD which are typical of other competitive radios on the market. THEN, they figured out a way to make an improvement, which makes them BETTER than the typical radio for this parameter. AND, they're willing to make the mod for free IF you handle shipping. Believe me, the "big-three" would simply come out with a Mark II, or "A" model and leave it at that. And, every time I hear that they did in fact do just that, I'm that much gladder (if that's a word) I have Elecraft's in the shack. If I'm wrong, I'm sure I'll hear about.

OK. Everybody ready to go out and buy a 28 volt power supply for the new K3S? The range of 12 volt supplies is way, way broader than 28 volt. The Astron LS35M 35A at 28VDC is 380 dollars. Oh, a built-in? Where does it go in the case? And does the K3S add an internal inverter to produce 12V for everything else from the 28V? Lot of expense for a small improvement that they can get with a freebee change to a late developing gift improvement for the cost of shipping. What would be a practical way to actually introduce such a change? Lay out all the specifics involved. Let's see your critical path item by item plan. It's cheep and easy to just blurt out "they oughta go to 28 volts." 73, Guy K2AV From k2av.guy at gmail.com Mon Oct 17 20:50:35 2016 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Mon, 17 Oct 2016 20:50:35 -0400 Subject: [Elecraft] SVGA/P3 Question -Waterfall Height Problem In-Reply-To: References: Message-ID: I do not have this problem, and I have P3/SVGA.

My first career was a buyer for an audio chain. I listened to everything they brought in. My assistant and my secretary and I NEVER agreed on what system sounded best. I would think a speaker that is reasonably flat from 200 hz to maybe 5khz with low mechanical distortion and good power handling would provide a decent baseline. After that - your warm tones are my screeching trebles; your full bass is my headache- inducing low range. I use a quality, small bookshelf speaker and then use the K3's equalizer to make the sound fill into the peaks and valleys of my ear's response curve. $50 would probably net you a pair of small Sony, Polk, KLH, JBL or even Pyle. New or used - you can't beat a nice rigid box with a woofer and a tweeter. Other interesting options are line-out to a Bluetooth audio source and then to one of the many Bluetooth wireless speaker systems. Or to a small stereo hifi amplifier. The K3 has stereo line output - a nice pair of bookshelf speakers left and right would definitely give you the best sound the K3/K3s is capable of producing (especially the K3s or an upgraded K3). A good audio setup will amaze you when you talk to another properly adjusted radio with a good microphone. There is a very broad range in the quality of signals on HF SSB. From dreadful to beautiful. I recommend setting up your station for the very best receive quality your radio can produce - which in the case of the K3, is substantial.

Wow Phil, right on. My first career was a buyer for an audio chain. I listened to everything they brought in. My assistant and my secretary and I NEVER agreed on what system sounded best. I would think a speaker that is reasonably flat from 200 hz to maybe 5khz with low mechanical distortion and good power handling would provide a decent baseline. After that - your warm tones are my screeching trebles; your full bass is my headache- inducing low range. I use a quality, small bookshelf speaker and then use the K3's equalizer to make the sound fill into the peaks and valleys of my ear's response curve. $50 would probably net you a pair of small Sony, Polk, KLH, JBL or even Pyle. New or used - you can't beat a nice rigid box with a woofer and a tweeter. Other interesting options are line-out to a Bluetooth audio source and then to one of the many Bluetooth wireless speaker systems. Or to a small stereo hifi amplifier. The K3 has stereo line output - a nice pair of bookshelf speakers left and right would definitely give you the best sound the K3/K3s is capable of producing (especially the K3s or an upgraded K3). A good audio setup will amaze you when you talk to another properly adjusted radio with a good microphone. There is a very broad range in the quality of signals on HF SSB. From dreadful to beautiful. I recommend setting up your station for the very best receive quality your radio can produce - which in the case of the K3, is substantial.

Floor will either be sealed concrete or maybe tile (embedded radiant heat in the concrete). But perhaps a area rug would dampen echos? This is how radio station booths are designed. Person on the mic sounds like next to you in your living room vs in a barn. re: speaker linearity and THD also important as freq range. I'm keeping my eight-inch National speaker in the big metal box. K3 sounds very nice with it. For very weak signals I will be trying out bluetooth direct to my hearing aids. I spent more for the hearing aids than my K3 plus accessories. 73, Ed - KL7uW Date: Mon, 17 Oct 2016 19:56:08 -0700 From: "Ron D'Eau Claire" To: Subject: Re: [Elecraft] Speakers - Optimal Frequency Range?

Provide an *optional* 28V PA that would drop into the existing space. If heat and/or maximum gain are an issue, it does not need to be specified for 200 W output ... 150/160 is good enough. As to power supplies, Yaesu had a dual voltage switching supply for the FT-1000MP MK V for many years. A "KPA4" could certainly have its own 28V connection to avoid changes to the K3/K3S (the present design keeps 13.8V on the PA all the time). Once one has a 28V option, the K3/K3S controller can be modified to limit power from the 12V KPA3A/KPA3B to 80 watts max which should further decrease IMD by keeping the FETs out of compression. Most published power transistor/FET data sheets show a sweet spot for IMD at around 60 - 80% of the CW ratings. 73, ...

I am trying to place macros in the P3 SVGA memories and have run into the problem that appears the K3 response time for doing band changes is preventing the ability to write a complex macro. Is there a way to insert delays into the macro to allow band change (possibly other functions) to complete? An example of what I am trying to do is below where a band change at the start results in having to run the macro twice to work. It depends on what prior band was in use. My desire is to switch from other bands/modes to specific operating frequencies and have the P3 span and center freq be specific.

The major issue is NOT sound on the air, but to minimize the sound heard by an operator while other operators are shouting into their mics. We contesters tend to get excited. Guys that have operated with the great operator Jerry, WB9Z, say that he doesn't need a mic! I visited W3LPL several years ago and noted no sound treatment at all in a room having only hard surfaces. I urged extensive sound absorbing materials. The room should NOT affect on the air sound if 1) you're working a mic within about 2 inches of your mouth, 2) TXEQ is set so that you're not transmitting below about 400 Hz, and 3) mic gain and compression are set so that you get no more than about 10 dB on voice peaks. 73, Jim K9YC From jim at audiosystemsgroup.com Tue Oct 18 13:51:12 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 18 Oct 2016 10:51:12 -0700 Subject: [Elecraft] K3S QST Article In-Reply-To: References: <97c2f34c-ecb3-fb87-b289-93d6cf2669a7@gmail.com> <22ff6588-0967-d97e-e799-2f2faa7830e7@ac0h.net> Message-ID: <5cd85434-9a74-4315-348e-8fbdb2e9e96b@audiosystemsgroup.com> On Tue,10/18/2016 3:43 AM, Yngvi (TF3Y) wrote: > How fast does IMD deteriorate with increased power from the K3S or K3? > > What are the IMD figures when running 20-25W driving a linear amp. such as > the KPA500? I've looked carefully at this, and so has my neighbor Bob Wolbert, K6XX, who is an engineer at Elecraft and a serious contester. The first link shows my measurements, the second is a pdf of the slides for a talk that K6XX gave to NCCC three years ago. It includes measured data showing how TX power out and DC voltage affect IMD. In my measurements, increased IMD causes CW bandwidth to increase. You can see that difference by comparing measurements at 30W, 50W, and 100W. http://k9yc.com/P3_Spectrum_Measurements.pdf http://k9yc.com/K6XXAmpTalk.pdf 73, Jim K9YC From jim at audiosystemsgroup.com Tue Oct 18 14:01:08 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 18 Oct 2016 11:01:08 -0700 Subject: [Elecraft] K3S QST Article In-Reply-To: References: Message-ID: Like Bill, I operate with several other hams for Field Day, CQP, 7QP (7th Area QSO Party), and VHF grid trips. Field Day is a single K3 for HF and a KX3 for the VHF station. We run 1A battery/solar. CQP and 7QP are multi-transmitter, K3/P3SVGA/KPA500 and run from Honda 2000i generators. These very nice generators DO produce some noise, and need a serious common mode choke on their output if they are close to antennas. (We operate from very quiet places in the middle of nowhere). When running power, we have double stubs on the output of the KPA500s feeding antennas for 80CW and 40CW, where the harmonics land on the next higher band.

But as a work around I would suggest setting the SVGA waterfall height to operate on its own, independent of the P3's waterfall height. To do that, press the MENU button on the front of the P3 and using the encoder, select SVGA Menu. Then select 'WfEn' and change it to 'Waterfall on'. In this mode, the SVGA's waterfall is controlled independently from the P3's waterfall. To adjust the SVGA waterfall, use SVGA Menu>WfHt. To adjust the P3's waterfall, use the regular P3 menu selection 'Waterfall' Also note that in this 'separate mode'. the SVGA screen 'unfollows' the P3's waterfall average, waterfall color, and waterfall markers settings. Refer to page 44 of the current P3 manual (revision H, available on our website) for more information.

My PX3 exhibits the same behavior in a system that includes the KXPA100. I see it happen when I twist the KX3's OFS knob to quickly QSY. However, if I turn OFF the the KXPA100 via the KX3 "PA MODE" menu option, the PX3 responds immediately to a twist of the KX3 OFS knob. If I turn the KXPA100 "ON" again, a quick turn of OFS results in the original sluggish PX3 response. Perhaps communications between the KX3 and the KXPA100 is at a higher priority than between the KX3 and the PX3. 73, Dale - WA8SRA > I have seen a similar issue with my PX3 but it may not be the same or it > may be related to the root of the problem. > > What I notice is what "in the old days" would be switch bounce.

The failure was quite unusual as it was an intermittent solder connection in that particular LPF. We rarely see that in this area on our professionally assembled and inspected boards. It must have been intermittent as it passed our automated board level and final K3S tests. As a double check we tightened our visual inspection of that area of the board and reviewed our test procedures. So far no other failures like this one found. 73, Eric /elecraft.com/ On 10/18/2016 2:51 PM, n9tf at comcast.net wrote: > Hi Eric, > Just curious/devils advocate question.

You may need some filtering on the 12V power connector in the center console of the Model S. The 12V battery is also quite small in the vehicle. I'd be inclined to package an LiFePO4 battery pack and a charger for it and place it in the center console area, powering the mobile rig from the LiFePO4 pack. That will give you surge capacity for higher power should you desire it, probably make any necessary 12V noise filtering easier and limit the stress on the 12V system in the Model S. For antenna mounting, you might consider adding a trail hitch adapter, and then mount the mobile antenna to that, using its bonding to prevent possible damage or modification to your vehicle. In the U.S., such a hitch is made by Torklift (www.torkliftcentral.com then click through Ecohitch and Tesla Model S) and seels for under $400 plus shipping and installation. It is invisible when not in use. I know a couple of Model S owners here in Tucson that have these hitches and are satisfied with their quality and durability. 73, Lyle KK7P On 10/19/16 7:45 AM, Johnny Siu via Elecraft wrote: > Thanks Bill.

This change greatly enhanced the operation of the select knob encoder. If you're experiencing severe 'jerkiness' of the encoder, it's usually a sign that the encoder is bad.

This instruction is buried/hidden in the manual - it does NOT appear on the page where it should appear, i.e. where the MIC SEL menu option is explained. I was planning to make a documentation improvement suggestion to Elecraft at some point about this, but I didn't get around to it yet.

I've been on the satellites for many years and recently started using 2 radios controled by SatPC32 software - one radio for uplink and another for downlink using converters. I decided to experiment with the K3 and P3 for the downlink side. It worked like a charm when 2 meters was the downlink (I should add that I'm using preamps for both bands placed at the antenna). Most of the satellites, but not all, use 70 cm for uplink and 2m for down. I then decided to try sending the output of both down converters, through relays switching, to the K3 transverter input. Only one band at a time would be selected by the relays and the other sent to the uplink radio. I tired using a Daiwa duplexer to accomplish this and I tried a simple splitter. For some reason this messed everything up and it seemed like the preamps were totally ineffectual, especially the 70cm preamp. I've been scratching my head to understand why this isn't working. This could be a wonderful satellite station using the K3 and P3 with or without the external monitor card for downlink. What am I missing? 73 Rick, W2JAZ From vr2xmc at yahoo.com.hk Wed Oct 19 21:00:05 2016 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Thu, 20 Oct 2016 01:00:05 +0000 (UTC) Subject: [Elecraft] operating HF / KX3 in a Tesla Model S In-Reply-To: References: <1551644396.2852938.1476849778666@mail.yahoo.com> <603829311.3458073.1476888349712@mail.yahoo.com> Message-ID: <1163370621.6452.1476925205794@mail.yahoo.com> Hello Lyle, Jim and Ignacy and others, Thanks for all your valuable advice. Hong Kong is small and good for Electric Vehicles. ? The population of EV has increased from 100 to now around 7000 in 5 years time. ?Regrettably, installation of chargers at condominium car parks is still a uphill battle. In fact, in terms of number of EV per km of roads, Hong Kong is the highest among the Asia Pacific. 73 Johnny VR2XMC ???? Lyle Johnson ???? elecraft at mailman.qth.net ????? 2016?10?19? (??) 11:41 PM ??? Re: [Elecraft] operating HF / KX3 in a Tesla Model S Hello Johnny! You may need some filtering on the 12V power connector in the center console of the Model S.? The 12V battery is also quite small in the vehicle.? I'd be inclined to package an LiFePO4 battery pack and a charger for it and place it in the center console area, powering the mobile rig from the LiFePO4 pack.? That will give you surge capacity for higher power should you desire it, probably make any necessary 12V noise filtering easier and limit the stress on the 12V system in the Model S. For antenna mounting, you might consider adding a trail hitch adapter, and then mount the mobile antenna to that, using its bonding to prevent possible damage or modification to your vehicle.? In the U.S., such a hitch is made by Torklift (www.torkliftcentral.com then click through Ecohitch and Tesla Model S) and seels for under $400 plus shipping and installation. It is invisible when not in use.? I know a couple of Model S owners here in Tucson that have these hitches and are satisfied with their quality and durability. 73, Lyle KK7P On 10/19/16 7:45 AM, Johnny Siu via Elecraft wrote: > Thanks Bill.?

The fwd lobe [in the plane of the loop] is very broad, very hard to discern the peak, so it really doesn't matter. The null [orthogonal to the plane of the loop] is very sharp, very noticeable. It can be used to null QRN/QRM, provided of course that the QRN/QRM is located in exactly that direction. Fortunately, because the fwd lobe is so broad, this actually does work fairly regularly.

If the plane of the loop is parallel to the ground, it is omnidirectional. If the loop is vertically oriented, it can be horizontally or vertically polarized, but in both cases, there is a sharp null in axis of the loop. (Technically, if the loop is parallel to the ground, the null points at the ground and the sky.) The vertical loop can be horizontally polarized by feeding it in the middle of the top or bottom edges. It can be vertically polarized by feeding it in the middle of the vertical edges. Changing the polarization may change elevation angle, and might affect ground wave propagated signals, but once it bounces, Faraday rotation makes polarization irrelevant.

Not seeing the 80M band DN going to 100MHz. Not seeing random 3xxMHz . Still have frequent jump down 1MHz . Removed Front panel, removed DSP board. Reseated both twice. . Working normally at room temp . Cooled off the K3 FP = 13 . Failing as above, 1MHz down shifts . FP = 15+ seems to be working OK . Cooled off the rig . Exercised frequency control and band changes via RS232 - this rig is also operated remotely - no failures noted . Other freq jumping as above occurring via manual tuning.

That's true for a loop having a full-wave circumference, but "Magnetic Loops" have circumferences that are typically only a fraction of a wavelength, and as such operate under a much different mechanism. A vertically oriented magnetic loop, regardless of where it is fed, will achieve the highest degree of coupling to a vertically polarized signal, and have a bi-directional (half-wave dipole-like) radiation pattern. A horizontally oriented magnetic loop, regardless of where it is fed, will achieve the highest degree of coupling to a horizontally polarized signal, and have an omni-directional radiation pattern. This is because a magnetic loop is most responsive to the magnetic component of the RF wave. When we speak of RF polarization, we are speaking of the polarization of the electric field. A vertically polarized signal will have a horizontally polarized magnetic field, and vice-versa. It is the horizontally polarized magnetic field from a vertically polarized wave front that will cut through the center of a vertically oriented magnetic loop and induce a voltage across its terminals. 73, de John, KD2BD From mbaileycrna at gmail.com Thu Oct 20 15:37:29 2016 From: mbaileycrna at gmail.com (Morgan Bailey) Date: Thu, 20 Oct 2016 14:37:29 -0500 Subject: [Elecraft] Mag Loop Message-ID: Having played with a Loop, I made one octagonal about 64 inches across, and mounted it vertical or perpendicular to the ground, I observed sharp nulls through the center of the loop. Additionally, I took a 4 or 7 watt flurescent bulb and while transmitting (low Power) ran the bulb from top to bottom and found that about ( reference feed point at the bottom, 6 o'clock position, im calling it zero degrees and tuning cap at the top, im calling 180 degrees or 12 o'clock position) 60 degrees about at 4pm point the bulb started to glow and was brightest at about 100 degrees 2:30 position and dropped back to dim to extinguished at 180 degrees. The loop was made for 20 and 40 meter operation. It is physically too large for 15 meter operation. When I made a tuning cap to resonate it on 80 meters knowing the efficiency would be maybe 3 percent, the only place the bulb lit was near the top with no glow from zero degrees 6 o'clock to 150 degrees or about 1-130 o'clock positions. All NVIS on 80 meters with a small loop. This was reinforced by its behavior on 20 and 40 meters. 40 had about a 5 or 10 degree higher angle of radiation over the 20 which was more evenly current distribution on the loop, with the main (brightest) lobe lower in the loop. So when we look at loops and directionality, the frequency of a multi band loop does change the radiation pattern. The bigger the loop for the band the more evenly distributed current was distributed along the loop. Up until the physical size of the loop does not follow the loop formula and gets too big to be considered a magnetic radiator. On 40 it radiated brightly at the 3 to 4 oclock positions but on 20meters, the current was more evenly spaced from about 430 to 1 oclock positions. On 20 it was brightest at about 245 positions. Maybe this is not scientific but my believe is that, this is demonstrating the angle of the lobes coming off the loop. It seems that it radiated well in the 20 to 30 degree take off angles on 20 and 40 meters with 40 meters being a bit higher more like 25 to 45 degree take off angles. Having this loop in my dining room on the floor of my house over a 3 foot crawlspace, I was able to work Europe repeatedly during the afternoon hours. I did this more than one time months apart. It was not a propagation fluke. Rig was 75 watts CW from a Yeasu FT 450d. I use it as my test rig. I built the loop to prove that they do not work....yet again I was proven wrong. My loop was made out of 1.5 inch by .25 inch thick Radiused edged aluminum bar. I got this from onlinemetals.com. I used radiused bar because RF does not flow around corners well. And, structurally, it was self supporting with a small bracket for a stand. And, it is just easier to work with flat stuff rather than round stock. By using the calculation on the web it performed identical to a 1.5inch copper tube. It was cheaper and much easier to work with. Additionally, I made it so it could be disassembled, yes I know the problem with resistance, don't go there, after all it is a compromise antenna and I was building it for portability and sturdiness. This loop really performed beyond my expectation. Was it better than a full sized vertical or a trap vertical with radials...Oh hell no, but I did make good contacts and even checked into many 40 meter and 20 meter nets from having it inside my house on the floor of my living room. I positioned the plane of the loop east west and was easily able to work both coasts and into Europe. Most of my contacts on it were on CW. See the attachment of it in my living room. When I rotated the loop 90 degrees on the axis the signals dropped from 2 to 6 S units, mainly depending on the distance from my location. The closer in the less drop. I attributed this to the NVIS component of the radiation (the 1 o'clock radiating area). [ATTACHMENT TOO LARGE FOR FORUM STANDARDS, IF YOU WANT A PIC I WILL GLADLY FORWARD IT.] Well this is my experience with my loop and here is a picture of the loop in its final configuration (see attachment) and no I don't want to be flamed about the construction but it works and with some fine emery paper and no-al-ox on the joints. It has a very sharp resonance and narrow band width of maybe 5kc 2to1. After that, it ,the SWR climbs like a wall > 25 to 1 But even though the SWR may be high off the sharp resonance transmit frequency, it still was a good rx antenna broad banded 100khz with very low noise. I can not say it was immune to but, it did not pick up electrical noise like the full sized vertical and the noise floor was lower than the typical vertical antenna. I have a full sized 40 and 20 meter vertical with 60 radials to compare it to and it does not get the same sig reports as that vertical but I did not expect it to. On occasion, with a preamp for rx (dx engineering one) copy was better on some stations over my outside vertical---only because of the reduced noise floor. It was a fun project and I really enjoyed the construction. They are not a miracle antenna but any antenna is better than no antenna and for many this may be the only option to be able to operate. Hell when I get moved into a retirement home, I will use it for a clothes rack and transmit on it when no one is looking. Since digital, PSK**, would be an ideal use for a loop as you don't need much power for the computer to do the heavy lifting. QRP signals are still good enough for computer ears, but not necessarily for ours.. LOL. In the end, it is another example of "QRP Works."

Your fluorescent bulb is responding to the voltage/current nodes around your octagon. Your loop is coupling to free space using the H-field, to which the bulb is pretty much insensitive. Because an electrically small loop couples via the H-field, it tends to be fairly insensitive to the ground and objects around it, so long as the permeability of the objects is roughly 1.0 [trees, rocks, you, anything non-ferromagnetic]. The ultimate radiation pattern resembles the winding on a toroid, expanded, with the null through the center. I worked a couple of DL's using my K2 @ 5W and AlexLoop from a summit in SE New Mexico on 15. Kind of sobering to realize that all the lines of force going everywhere several thousand miles away come together through the center of the little loop directly over my head, and a tinfoil hat won't help. If you're parked on the tracks in a railroad yard, things will be somewhat different. :-) Be careful with your loop, even very moderate power levels will involve very high voltages and circulating currents.

They are E-field antennas [just like a half-wave dipole or 1/4 wave vertical] and the feed point determines the polarization. Polarization matters at VHF and above, but at HF, the received polarization will be random and changing due to Faraday Rotation in the ionosphere. I believe this thread is about "small magnetic loops," whose circumference is only a handful of degrees, such as the AlexLoop [a resonant transformer], and others directly fed. The feed point does not matter for small magnetic loops. 73, Fred K6DGW - Sparks NV DM09dn - Northern California Contest Club - CU in the Cal QSO Party 7-8 Oct 2017 - www.cqp.org On 10/20/2016 4:27 AM, Steven Dick wrote: > The vertical loop can be horizontally polarized by feeding it in the > middle of the top or bottom edges. > It can be vertically polarized by feeding it in the middle of the > vertical edges.

When the temp is low, maybe there are some bad contacts. Take off the front panel and clean all pins of the connections.

" This isn't the case for most antennas we use which launch an electromagnetic wave by generating an electric field. Ground characteristics affect the pattern of a vertically polarized wave much more than they affect a horizontally polarized wave for these types of antennas. The mag loop however, as I understand it, launches an EM wave by generating a magnetic field. Do the ground characteristics not affect the pattern of a magnetic field the way they do an electric field? If they do have the same affect, then the above statement isn't true.

This was noted during a power out on all bands of the ?TUNE? function with ATU in BYPASS. Initially KX2 was matched using the ATU on various bands with antenna presenting load not ideally matching 50 Ohms. The line SWR was > 4:1 in some cases (measured in ATU BYPASS). The matched (ATU AUTO) SWR indicated 1.2 or 1.3 : 1 on each band. Connecting a 50 Ohm load and using an Oakhills Research Wattmeter, a check of the power out was performed for all bands using the TUNE (3W) function in the ATU BYPASS mode. The SWR as measured by the KX2 indicated 1.2:1 on each band. Power out ranged 3.8W (80M) down to 3.2W (10M) as measured on the watt meter, which is acceptable. Reflected power was essentially ?0? on all bands. Setting the ATU back to AUTO, and performing an ATU TUNE on all bands, then resulted in an indicated SWR of 1:1 using the TUNE(3W) function. Setting the ATU back to BYPASS, the SWR as measured by the KX2 indicated 1:1 when TUNE (3W) was initiated on each band. Is there an issue with the way the fw updates the SWR measurement for display?

In-Reply-To: References: Message-ID: <4a992d2f-e922-a643-8a25-5bc11acfa9f9@audiosystemsgroup.com> Hi Jim, I'm doing exactly that, but with a Ten Tec Titan 425 rather than the 1500. My method is pretty simple -- I'm using two of W2VJN's 1x2 Top Ten relay boxes, one at the inputs, the other at the outputs. They work well, except that the SWR is pretty poor on 6M (and is starting to rise on 10M) because these boxes use the chassis as the signal return rather than carrying it on the circuit board. To clarify, only a single wire goes from each coax connector to the circuit board. And even if the shield was carried, the return layer is broken on the return layer. I put a "band-aid" on the SWR problem by adding the return path, and by adding a small stub on the output of the switch on the KPA500 side. To add the return path, you need to run a short piece of braid from each coax connector to the circuit board near where the center conductor is terminated, and add short sections of braid across the board following the signal path from input to each of the outputs. That reduces the SWR by half, the stub finishes it off. Other vendors make similar boxes, but I haven't seen them, so I don't know if they do the signal return correctly or not. I don't recall the exact length of the stub, but I think I recall that the alternative was a cap of about 11 pF. 73, Jim K9YC On Sat,10/22/2016 4:12 PM, Jim Miller wrote: > I'm considering adding a bigger amp to the shack.

Not important, but I have an Array Solutions Power Master II wattmeter with two couplers connected to the amplifiers' outputs. My approach is pretty low tech. I have the 87A connected to the K3's ANT2 port and the KPA500 connected to ANT1. I use an Alpha Delta manual coax switch to switch my only antenna coax between the two amplifiers. (I considered using a spare Daiwa switch but it's not rated at 1500W.) I looked up the inter-port isolation for the antenna switch when I connected it, and it seemed adequate, but I don't remember the specs. The only thing that's a bit fancy is a macro I did recently to use in my K-Pod. I don't switch amplifiers often so I used two press-and-hold buttons on the K-Pod. KPA500 MN058;MP123;MN081;UP;MN255;AN1; 87A MN058;MP000;MN081;UP;MN255;AN2; You can either look through the K3 Programmer's Reference Manual if you want the mental exercise or read my notes below: MN058 - menu MP123 - sets K3's tune power to 15W (just my preference). MP000 - sets K3 tune power to NOR (not per band) MN081 - toggles between per band power for the KPA500 or NOR for the 87A. MN255 - exits the menu AN1/AN2 - selects antenna 1 or 2. 73, Jim N7US -----Original Message----- I'm considering adding a bigger amp to the shack.

You have to use the KPA500 KEY INTERRUPTER in this situation. It is attached at the KPA500 AUX. The AUX cable goes from the K3 ACC to the KEY INTERRUPTER that is plugged into the KPA500 AUX. If you have the KAT500 as I do the AUX cable goes from the K3 ACC to XCVR on the KAT500 then an AUX cable from AMP on the KAT500 to the KEY INTERRUPTER plugged into the KPA500 AUX. Then to control each amp's keying I have a RCA Phono Y plugged into the K3 KEY OUT. One side of the Y goes to the 9500 KEY IN. The other side goes to the KPA500 PA KEY or top RCA Phono PTT RLY connector on the KAT500 if you are using a KAT500. Then a key line jumper from the bottom PTT RLY RCA Phono connector on the KAT500 to the PA KEY on the KPA500. When both amplifiers are powered up, the one not being used is in standby. When in standby the amp will not be keyed. I hope all that makes sense. If not, let me know and I will try and clarify it.

I used a pair of surplus coaxial relays to switch the inputs and outputs. I have my amps set up with a 12v 'enable' input which operates a relay to put the amp in standby or operate mode, and the switch that operated the relays also switched this line. I simply isolated the amp key lines with diodes, because when the amp was in standby, the key line was disabled. Just some ideas.

(This applies equally to the K3S, at either end.) Here's the applicable release note: * * * K3 MCU 5.55 * KPOD WORKS IN REMOTE-RIG TERMINAL MODE: The K-Pod will now function correctly with a K3 or K3/0-mini being used as a remote-rig terminal. Basic functions of the K-Pod can be used, including switch tap / hold and VFO A/B/offset control. LEDs and AUX outputs of the terminal K-Pod are not yet supported. Note: At present, when switches on the terminal K-Pod are used, they will execute macros stored at the remote K3. This will be apparent when macro names are flashed on VFO B. * * * If you're interested in testing this new capability, please email me directly. 73, Wayne N6KR From donwilh at embarqmail.com Sun Oct 23 15:11:59 2016 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 23 Oct 2016 15:11:59 -0400 Subject: [Elecraft] Adding 222 mhz to K2 In-Reply-To: <157f28e8c71-229a-866@webprd-m77.mail.aol.com> References: <157f28e8c71-229a-866@webprd-m77.mail.aol.com> Message-ID: Mike, The native K2 (with options) has only bands 160 thru 10 meters. If you have 50MHz on it, it must be by using a transverter. How to physically add the 222MHz transverter should come from the 222MHz transverter manual and perhaps also the 50MHz transverter manual. There is some information in the Using Transverters section in the base K2 manual - download if you do not have it. Download the Elecraft XV series transverter owners manual to give you some information about how to connect the transverters and configure the menu. The TRNx entry in the K2 sub-menu (TRNx RF) setting will allow you to read the transverter frequency on the K2 display. There are other TRNx functions to set the IF band, the transverter offset (to compensate for the LO in the transverter not being exact) and the power level. If your K2 has the K60XV option, you can use the low power outputs. 73, Don W3FPR On 10/23/2016 1:20 PM, WB8PFZ via Elecraft wrote: > I am the proud owner of a K2 that has 50 mhz.

The Z-bracket attaches to the front and back panels, the bottom cover and to the top. Make sure you got all the screws tight. Also, be sure you installed the transformer correctly, including the rubber disk between the transformer and the bottom cover and you have the bumpers in place where the transformer rests against edge. Be sure the Bellevue washer is installed right side up. That's the washer under the nut holding the transformer in place. As the text explained, it is very slightly conical and must be installed so the center hole of the washer is slightly higher than the edges. Put it on the desk and tap on the edges of the washer with a pencil. If it rocks a bit, it is upside. If it is right side up, it will sit still. Be sure it is installed right side up. Finally, tighten the nut on the Bellevue washer a bit more. If you have a torque wrench available, it should be set to 55 in/lbs but it is not real critical. As the text says, run the washer down onto the Bellevue washer, and then tighten one or two turns further. IF needed add a bit more to quiet it! My KPA500 hums under full load, but not loudly - about as loud as my Astron power supply under full load. If anything is "buzzing" it is certainly a loose fastener somewhere. 73, Ron AC7AC On Sun, Oct 23, 2016 at 5:46 PM, W1GO (Joe) wrote: > > Hi all, > > Finished assembly of KPA500 and a little surprised at the magnitude of > hum / buzz during CW (no real issue on SSB); I've read about it but was > surprised at just how pronounced it is.

Contact Elecraft support for further assistance. If you are willing and capable of handling such problems yourself, they can provide pointers for you, otherwise you will likely have to send it in for repair.

Unfortunately, those are masked to a search of the .pdf of the manual because they are images in the manual. See page 12 (last column) for the definition of the OFS/B knob. The use of the UFS LED is in the RIT and XIT text on page 16 - similarly the VFO B shows use of the B LED on page 16. Also see pages 5 and 23 for the use in Special VFO B displays. Page 5 indicates that the VFO/B knob is used to scroll through the menu entries. Use of the knob for selecting data submodes is on pages 27 and 28. Use of the knob for Text Decode is on page 29. I may have missed a few of the references to the OFS/B knob images or the OFS and B LEDs, but the above are a few of them. OFS is an abbreviation for OFFSET. 73, Don W3FPR On 10/23/2016 9:20 PM, Emory Schley wrote: > OK, I'll try this again... > > I'm the new owner of a KX2 and am trying to learn all I can about the rig.

Does the K3S need to be switched off of safe mode for the PTT-PTT settings to not change? ? PTT/KEY USE WITH THE USB PORT IMPROVED: Some PC applications can control PTT and KEY at the K3S via the RTS/DTR signals of the USB port. However, use of these signals may also allow the PC?s USB port initialization to unexpectedly activate transmit at the K3S. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on. Applications that use PTTKEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S. ? http://www.elecraft.com/manual/E740258E%20K3S%20Owner's%20man%20errata%20A1-2.pdf ?

This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency.

Message-ID: <201610241953.u9OJrXbL021456@mail42c28.carrierzone.com> Just warning about the CX-600NL. I initially used them for TR relays on 2m-eme at 100w to 600w with no problems but once I increased power to >800w the relays began to fail. The contacts apparently not able to carry higher RF current as they eventually heat and melt the center wiper usually such that it shorts the coaxial section -- Not a nice thing to do to a 1500w amp. As I said I have had three fail this way. I use sequencing so absolutely not due to hot switching (at least 30msec delay before RF applied). Maybe they will handle HF power better (I do not have HF QRO). Also when running 2m-eme my 8877 is key down for 50-seconds under JT65 and key up for 70-seconds, which repeats as long as in transmit. So this is "almost" Alpha brick testing! When one of the relays shorted I noted that my 8877 output went to 1800w and drew over an amp at 3000v. Fortunately I noted this quickly and shut it down. Grid current was higher but apparently no harm to the 8877 (what a really tough tube -- I have eight years running on the same tube). I use a G3SEK Triode Board for bias, warm-up delay and overcurrent protection for both anode and grid. Two coax relays probably work as well as a transfer relay for the two amp application. Make sure the output relay can handle the max power. I have one surviving CX600NL which is used to select either 1296 amp or 900 amp at my tower top (both low power level drive input for the amps). I now use NARDA sem123N (1200w at 150-MHz) in the high power ckts. 73, Ed -KL7UW From: "Joe Subich, W4TV" To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500/KAT500 paired with AL-1500?

What I'm wondering is, what is the orientation of the 4 turn loop with respect to the copper tubing loop? You don't mean that you wound the 4 turns around the copper pipe do you? The two loops should be in the same plane, perhaps offset, but you should be able to stick a rod through both loops.

I'm sure he'll be fair, as he always is. -- 73 Carl N8VZ > Carl J?n Denbow > October 19, 2016 at 12:39 PM > Thanks, Matt. Problem solved. Actually, it wasn't a problem.

For instance, the Elecraft K3's (after synthesizer upgrade) number is 103 dB, good enough to be in the top ten. In fact, this number is so strong that very few hams will ever be affected by it. To the best of my knowledge, I have *never* been close to running out of dynamic range. To understand why, let's put "103 dB" into English. Let's say you're on 20 meter CW, operating at 14.050 MHz. You're listening through your fine Elecraft 500 Hz crystal filter when suddenly, and by incredible coincidence, two equally strong 49 dB over S9 signals begin transmitting at the exact same time, one on 14.052 and the other at 14.054 MHz, exactly 2 kHz and 4 kHz up from where you're listening. With the preamp off (which is totally believeable on 20 meters with a decent antenna) you will just barely hear a "ghost signal" right at the noise level... if you notice it at all. That "ghost" signal is the two-tone, 3rd order intermod product generated in the K3 receiver by those two hugely strong and perfectly placed signals. Not a very likely scenario, but that's what 103 dB of dynamic range buys you. I have assumed a noise floor or MDS of -130 dBm because it's a nice round number. If your 20 meter noise floor is higher than this, then the two signals would have to be *even stronger* to hear the intermod come out of the noise. Even if each of those interferers was *60* dB over S9 -- pegging the S-meter-- the intermod product on 14.050 would still be only S5. Amazing. This kind of performance begs the question, "How much more dynamic range is really needed?" and some (like Rob Sherwood) have said that once you're above 90 dB, you already have enough, at HF at least. Perhaps it's time to rank receivers by a different measurement, something that affects more of us. Looking through the table at the link above we see another measurement called "2 kHz blocking gain compression" and for the same K3 it is 143 dB. This is a measurement not of two interfering signals, but a single interferer just 2 kHz away. Since there's only one signal, it won't generate a "ghost", but it will reduce the gain of the receiver. ARRL defines this as the signal level that reduces the gain by 1 dB. One dB is really small, something like changing your RF Gain knob from the 3:00 o'clock position to maybe the 2:45 o'clock position. Barely noticeable. Nonetheless, for our K3 the signal required to do this is about +13 dBm, or 20 milliwatts, which is probably near the damage level of the receiver! (I'm quite sure that Wayne has made intercontinental QSOs at 20 mW.) It's a theoretical value that very, very few hams would ever encounter... only the ones living next door to a guy running a kilowatt. So this measurement is even less relevant to us. Finally, we notice a measurement called "2 kHz reciprocal mixing dynamic range" -- probably the limiting spec nowadays for top tier receivers. In our example of the single strong signal, way before reducing the gain of the receiver, that signal will have another effect: it will mix with the phase noise of the K3's own local oscillator and deposit that phase noise right onto your desired frequency of 14.050 MHz. As you're listening there, you suddenly notice that the noise floor seems to be rising for no apparent reason. You listen some more, and notice that the noise is following some kind of CW keying. You glance at your panadapter and notice an enormous signal just 2 kHz away on 14.052. So there are two culprits: that strong signal, and the K3 oscillator phase noise. The K3 with upgraded synths has a spec of "-115 dBc", again near the top of the list, which means that a signal 2 kHz away and 115 dB above the noise floor will cause the noise floor to rise by 3 dB. For a K3 noise floor of -130 dBm this is -15 dBm, or about 60 dB over S9. The reason I say this is the limiting factor is because the chance of just one 60 dB over S9 signal nearby is greater than *two* of them at the right spacing as in our discussion of 3rd order DR. For these reasons, we could start ranking receivers by 2 kHz reciprocal mixing dynamic range because reciprocal mixing is far more likely to happen to a larger number of hams. It's not a catastrophic effect, but it's quite noticeable. There's a problem, however, because sampling receivers don't follow the classical reciprocal mixing model. We need a measurement that hasn't been invented yet to compare modern receivers. Maybe we could simulate the worst-case contest by applying thousands of signals and noise to the receiver and seeing how much junk is generated to cover up the signal you're trying to copy at 14.050, something kinda like the noise power ratio test. But in order to compare apples to apples, the exact same test conditions must be used on every receiver, regardless of architecture. Finally, the general unlikelihood of any of these conditions occurring also convinces me that other ergonomic factors -- not necessarily measureable-- should be considered when choosing a receiver. 'Usability' (whatever that means to you) is underrated. So is 'listenability' -- again, a very subjective term. For instance, I have come to believe that the AGC system in a receiver has everything to do with how it "sounds" and explains why receivers with similar specs can sound so different from each other. This area needs further study. I hope that this helped turn mere numbers into an actual operating reality.

It's nice to know that the K3 ranks high on the charts, but I agree that 'usability' and 'listenability' are underrated. Before I purchased my K3, I went to AES in Wickliffe and listened to several receivers. I liked the sound of the Kenwoods, but I liked the 'modularity' of the Elecraft K3. I was also influenced by my conversations with Eric and Wayne at Dayton. 73, Art WB8ENE On Tue, Oct 25, 2016 at 1:21 AM, Al Lorona wrote: > Receivers are always ranked by the "2 kHz third order dynamic range", such > as at: http://www.remeeus.eu/hamradio/pa1hr/productreview.pdf but do we > really grasp the meaning of these specs?

I want to know how well a receiver is able to separate a weak signal from strong signals 50-100 Hz away. It would be interesting to speculate how such a measurement would be done. Let the RX use whatever analog or digital tricks it can to achieve the above. Your idea of simulating a contest with a hundreds of signal injected at various random frequencies to gauge RX performance has merit. Have you overlooked the MM, FD and DXpedition RX uses which in fact push the dynamic range and mixing limits today? There are MM stations which operate two transmitters on the same band. 73 de Brian/K3KO On 10/25/2016 5:21 AM, Al Lorona wrote: > Receivers are always ranked by the "2 kHz third order dynamic range", such as at: http://www.remeeus.eu/hamradio/pa1hr/productreview.pdf but do we really grasp the meaning of these specs?

The listen ability and ease of ergonomic operability are the reason I love radios with knobs. This is what the maestro is trying to do for for the Flex 6XXX radios. There is just not a better box for both on the market other than the K3, K3s, KX3, KX2. Seemingly Elecraft has nailed it. Your post only confirms what I believe all Elecraft owners already know and experience when we hit the power on switch. Again you summary is excellent and great reading. Well written and well thought out and equally well presented. Strong work.

That is noise/RFI reduction. The Pandora's box of RFI has been opened and can't be shut at this point. We need to address the issue of noise reduction and noise blanketing in some quantitative way to compare various RX's. Right now the "comparisons" are all innuendo, e.g. "my old xyz rig did a much better job at noise blanketing power line noise than my new widget." The recent QST article on the K3S singing the praises (without giving any data) of its NR and NB capability is another example. This would be tough since the world of RFI sources is huge. It would take some real effort to quantify the world of noise sources and their signatures and then find some algorithms to deal with them. Impossible? The world of big data isn't so big any more. Such an catalog might be doable. Algorithms are another issue. My hope is that NR/NB could be made adaptive to recognize the signature(s) and generate appropriate algorithms on the fly. There are a lot of smart people out there who could perhaps address these issues. Unfortunately commercial interests have to see some payoff. They haven't as of yet. The fact that AM broadcasters are being burned by RFI and becoming proactive is a plus. 73 de Brian/K3KO On 10/25/2016 14:32 PM, Bill Frantz wrote: > Before I bought my K3, I discussed the radio with someone in the booth > at Radiofest, a small hamfest held near Monterey, CA.

The 2kHz test results does indicate that to me. Just how much improvement is gained for each receiver is open to some question, and depends on what tools are available and used. Certainly the K3(S) APF function would be of help with its 30Hz peak, but if testing is to be conducted using very closely spaced multiple signals, then it would be necessary to specify which of the interference abatement tools were used on each receiver. I doubt if Rob Sherwood would want to buy into that form of testing, there are simply too many variables in that all receivers do not have the same interference fighting tools. A long time ago, I built a receiver based generally on the HBR-16 design, except that it used a double-coupled 85kHz IF instead of the 100kHz IF. I added a Q-multiplier stage at 85kHz, and it was fantastic at pulling a signal out from the 'mud'. I have no idea about the dynamic range or the 2kHz test for it, but it was quite capable. The K3(S) APF provides similar capability to the Q-multiplier of old. 73, Don W3FPR On 10/25/2016 10:32 AM, Bill Frantz wrote: > > I like Brian's idea of simulating contest conditions to test receivers. > Such a simulation would need to be reproducible and good enough that it > can't be gamed.

Comments preceded by asterisk * inserted below: --------------------------------------------------------- Date: Tue, 25 Oct 2016 05:21:20 +0000 (UTC) From: Al Lorona To: Elecraft Reflector Subject: [Elecraft] [K3] The Way We Rank Receivers (long) Receivers are always ranked by the "2 kHz third order dynamic range", such as at: http://www.remeeus.eu/hamradio/pa1hr/productreview.pdf but do we really grasp the meaning of these specs? For instance, the Elecraft K3's (after synthesizer upgrade) number is 103 dB, good enough to be in the top ten. In fact, this number is so strong that very few hams will ever be affected by it. To the best of my knowledge, I have *never* been close to running out of dynamic range. To understand why, let's put "103 dB" into English. ===snip I have assumed a noise floor or MDS of -130 dBm because it's a nice round number. If your 20 meter noise floor is higher than this, then the two signals would have to be *even stronger* to hear the intermod come out of the noise. *I wonder where in the world one sees a 20m noise floor that low when antenna is connected? Only when I lived off the grid running on battery power did I see S0 noise on my radio (3.9-KHz with TS180S from a dipole). I doubt that radio had a noise floor that low, but maybe. I see S3/5 noise on my K3 connected to triband yagi, preamp off. That is probably about -110 to -100 dBm noise floor. My SDR-IQ is very good at 28-MHz and displays -132 dBm without an antenna connected (190-KHz bandwidth). But connecting an antenna raises that instantly. ===snip Perhaps it's time to rank receivers by a different measurement, something that affects more of us. Looking through the table at the link above we see another measurement called "2 kHz blocking gain compression" and for the same K3 it is 143 dB. This is a measurement not of two interfering signals, but a single interferer just 2 kHz away. *I can only think of two instances seeing such a strong adjacent signal: 1) At 310-KHz a GPS-reference station is locate less than a mile away and I measure it at -30 dBm on my inverted-L (tuned to 490-KHz) with SDR-IQ. 2) I once measured a high power pager running 158.100 100-foot away from my company's 161.325 repeater showing 1/4w on the Bird power meter installed on the repeater antenna whenever the pager transmitted (repeater was turned off). That would be +23 dBm. Amazingly the repeater Rx survived this (due to duplexer and helicoil prefilter). IMD mixing of the 158.1+161.325 produced a horrendous signal on 156.450 (which interfered marine ch.9). Both examples extremely unlikely to occur for HF hams. ===snip Finally, we notice a measurement called "2 kHz reciprocal mixing dynamic range" -- probably the limiting spec nowadays for top tier receivers. In our example of the single strong signal, way before reducing the gain of the receiver, that signal will have another effect: it will mix with the phase noise of the K3's own local oscillator and deposit that phase noise right onto your desired frequency of 14.050 MHz. *this has application for me. The occurrence of a high power signal off frequency mixing with the phase noise of my eme Rx. This is one of the reasons driving a goal for extremely low LO phase noise in eme systems. This is one of the major selling points for me to purchase my K3 and upgrade synthesizers. ===snipped the rest (though very interesting proposal) 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From wunder at wunderwood.org Tue Oct 25 17:43:39 2016 From: wunder at wunderwood.org (Walter Underwood) Date: Tue, 25 Oct 2016 14:43:39 -0700 Subject: [Elecraft] [K3] The Way We Rank Receivers (long) In-Reply-To: <201610252131.u9PLVt8H022181@mail46c28.carrierzone.com> References: <201610252131.u9PLVt8H022181@mail46c28.carrierzone.com> Message-ID: <16BF83BF-787F-4624-9A8A-2FB277D3D094@wunderwood.org> > On Oct 25, 2016, at 2:31 PM, Edward R Cole wrote: > > I wonder where in the world one sees a 20m noise floor that low when antenna is connected?

Here's what I think I know so far: 1. The KAT seems fine. 2. The P3 Output Monitor thinks it sees 0.6W on the antenna line after the KAT. 3. This implies to me that the K3S thinks it is tuning with 25W, but it isn't. 4. This implies that the KAT isn't tuning due to low drive (and maybe it's already tuned). 5. Last night when I ran one of the Utilities, probably the KPA one, I though I saw an Fxx code streaming into the text box on the MACRO tab of the utility. I thought it might be F00F00F00, but I'm not sure. That could be some communications error between the KPA and the K3S, but it isn't happening now. 6. The HIGH SWR display at the K3S is 11:1 plus/minus in TUNE (25W) when the KPA is STANDBY and 9:1 plus/minus when in OPERATE and 15:1 when the KPA is OFF. In all three situations the K3S thinks it is outputting 25 watts, but it doesn't seem to be. 7. If I key the radio in KPA OPERATE it looks like the KPA is outputting 30 or 40 watts if you trust the display. Varying the K3S output doesn't have a corresponding change in KPA display, it just moves from 30 to 40 to 30 out. That happened once but I cannot repeat that test result. 8. I have powered-off the KPA with the rear switch and discconected "the mains". This should have reset any hard faults. 9. The FAULT LOG shows the last error as "60V Supply Over limit" if the latest is at the top, or "Excessive Reflect4ed Power (High SWR)" if the latest is at the bottom. There is no timestamp so I cannot be sure when these occurred, but an occasional HIGH SWR happens as I tune and fiddle with antennas. (Sometimes I forget to retune a segment.) Should I suspect control cable issues or something internal to the KPA?

Go into device mgr and you will see four new ports: RRC1258 COM0(COMw) RRC1258 COM1(COMx) RRC1258 COM2(COMy) RRC1258 COMExtra(COMz) 5. Note the "x" for RRC1258 COM1. Use that COM port# in your logger for the CAT control. 5. It is possible that Windoze may have assigned a COMx that is already in use. Do not try to change the RRC1258 assignment! Go into the other [duplicate] port and change it to something unused. Whatever is using that port will likely have to be adjusted as well. #5 above is brought to you by Windoze 7, 8, and 10. You can thank Microsoft for that feature. 73, Fred K6DGW - Sparks NV DM09dn - Northern California Contest Club - CU in the Cal QSO Party 7-8 Oct 2017 - www.cqp.org On 10/25/2016 3:29 PM, Mike Murray wrote: > Got the RemoteRig setup working great except for one small wrinkle - > logging.

And thanks to several others who offered even the smallest suggestion. To describe the circumstances: K3S->KPA->KAT->ANT When opening the station Monday evening, the KPA was producing no output. I had attempted to work an easy QSO for me, but called for several minutes before I noticed the power was at zero. Nothing out of the KPA. As I went through my usual "what happened now", which means "what happened last year that looked like this" I tried the K3S TUNE to see if I was in a band segment that hadn't been recently updated. But, the K3S showed it was outputting 25 WATTS with an SWR of 11-15:1 - unlikely. And the KAT was making no attempt to tune. And the KPA still had zero output. Long story, in hours, short after determining the K3S was fine, then the K3S->KAT were fine and then the KPA was not, I retested the reconnected KPA after resetting the CONFIG using EDIT+ON at power-up and things are back to operation. Thank you Mike, thank you everyone else, and thank you Elecraft for the EDIT+ON option.

In order to access CAT, you need to get to COM2 without touching it. The easiest method is to duplicate COM2 over COM1 using a function in the RRC as follows: - Change both RRC's COM1 to mode-7. Note that the baud rate does not have to be identical with COM2 to fit a lower bandwidth or software requirement. - If using a "real" serial cable: - connect between the control RRC's COM1 and the PC, but note that the pinout is not the standard straight-through serial port. Use the pinout description in the RemoteRig manual, or just try a null-modem cable which usually works (may need a gender changer). - The serial setting for COM1 "Use USB Com Port as COM1" must be set to NO - If using USB: - make sure that first Microbit Setup Manager is installed first on the control PC to get the drivers. - Then change the serial settings for COM1 to change "Use USB Com Port as COM1" to YES - connect the USB cable between the RRC and computer and wait for the drivers to finish installing - go to the Windows Device Manager and look at which virtual serial port was assigned to COM1 and use that for your software, taking the correct baud rate into account. Note also that you can pull CAT data in parallel off of the radio RRC to use a PC on that end, or to sync with a remote device (amplifier, SteppIR, etc.) 73, Mitch Mitch Wolfson DJ?QN / K7DX 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile:+49 172 8374436 On 25.10.2016 19:01, Fred Jensen wrote: > I'll repeat back what I think I understand about your current setup: > > You have a serial-USB adapter plugged into the female DE-9 labeled > "COM1" on the front of the RRC-1258, the other [USB-A] end is plugged > into a USB slot on your computer, and device mangler tells you it is > "COM3". > > If that's exactly what you meant, I have never been able to make that > work with N1MM+.

So I would like to make a feature request; A new K-Pod macro controlling rocker-switch function so that the macro switch the main know function.

Please review the recent release notes below. If you'd like to do testing because you'll be affected by these changes, or if you're just interested in helping us qualify the firmware for beta release, please contact me directly. 73, Wayne N6KR * * * K3 MCU 5.56 / DSP 2.88 / FPF 1.26, 10-26-2016 * SCANNING WORKS WITH FREQUENCIES BELOW 1.0 MHz. Previously, scanning would stall in this case. * REDUCED K-POD MACRO FLASH TIME: If text decode is enabled, then the length of time that K-Pod macro names are flashed is greatly reduced. This reduces the obstruction of text shown on VFO B. * DT, FR, and FT HOST COMMANDS DISALLOWED IN TX MODE: Previously, these commands (data submode, split off, and split on) could be sent to the K3 during transmit from software applications. This could sometimes cause side effects such as muting of transmit audio in DATA modes. K3 MCU 5.55 / DSP 2.88 / FPF 1.26, 10-20-2016 * KPOD WORKS IN REMOTE-RIG TERMINAL MODE: The K-Pod will now function correctly with a K3 or K3/0-mini being used as a remote-rig terminal. Basic functions of the K-Pod can be used, including switch tap / hold and VFO A/B/offset control. LEDs and AUX outputs of the terminal K-Pod are not yet supported. Note: At present, when switches on the terminal K-Pod are used, they will execute macros stored at the remote K3. This will be apparent when macro names are flashed on VFO B.

We are also releasing the K-Pod Utility (Windows, OSX, Linux) which is used to program your K-Pod. Like all other Elecraft products, the Utility will automatically download the latest version of firmware. Please BE SURE TO READ the K-Pod manual before attempting to download firmware. We're also releasing rev.D of the K-Pod manual. In it you will find information on how to write macros on the K3 that control the LEDs and outputs on the K-Pod. For developers, this release also includes the K-Pod USB API spec. This document explains the USB HID interface command set and report formats.

You're listening through your fine Elecraft 500 Hz crystal filter when suddenly, and by incredible coincidence, two equally strong 49 dB over S9 signals begin transmitting at the exact same time, one on 14.052 and the other at 14.054 MHz, exactly 2 kHz and 4 kHz up from where you're listening.

Looking through the table at the link above we see another measurement called "2 kHz blocking gain compression" and for the same K3 it is 143 dB. This is a measurement not of two interfering signals, but a single interferer just 2 kHz away. Since there's only one signal, it won't generate a "ghost", but it will reduce the gain of the receiver. ARRL defines this as the signal level that reduces the gain by 1 dB. One dB is really small, something like changing your RF Gain knob from the 3:00 o'clock position to maybe the 2:45 o'clock position. Barely noticeable. Nonetheless, for our K3 the signal required to do this is about +13 dBm, or 20 milliwatts, which is probably near the damage level of the receiver! (I'm quite sure that Wayne has made intercontinental QSOs at 20 mW.)

In our example of the single strong signal, way before reducing the gain of the receiver, that signal will have another effect: it will mix with the phase noise of the K3's own local oscillator and deposit that phase noise right onto your desired frequency of 14.050 MHz. As you're listening there, you suddenly notice that the noise floor seems to be rising for no apparent reason. You listen some more, and notice that the noise is following some kind of CW keying. You glance at your panadapter and notice an enormous signal just 2 kHz away on 14.052. So there are two culprits: that strong signal, and the K3 oscillator phase noise. The K3 with upgraded synths has a spec of "-115 dBc", again near the top of the list, which means that a signal 2 kHz away and 115 dB above the noise floor will cause the noise floor to rise by 3 dB. For a K3 n > oise floor of -130 dBm this is -15 dBm, or about 60 dB over S9. The reason I say this is the limiting factor is because the chance of just one 60 dB over S9 signal nearby is greater than *two* of them at the right spacing as in our discussion of 3rd order DR. > > For these reasons, we could start ranking receivers by 2 kHz reciprocal mixing dynamic range because reciprocal mixing is far more likely to happen to a larger number of hams. It's not a catastrophic effect, but it's quite noticeable. There's a problem, however, because sampling receivers don't follow the classical reciprocal mixing model. We need a measurement that hasn't been invented yet to compare modern receivers. Maybe we could simulate the worst-case contest by applying thousands of signals and noise to the receiver and seeing how much junk is generated to cover up the signal you're trying to copy at 14.050, something kinda like the noise power ratio test.

Rather it is a problem with your power supply or the power cable. Check the voltage at the center pin of the coaxial DC power jack. If it is showing the same thing as D10, then you either have a bad power cable or a bad coaxial power jack. OTOH, if the voltage at the center pin of the DC coaxial jack is OK, and the voltage at D10 drops significantly, look on the bottom of the RF board to see if the power PC trace between the coaxial jack and D10 has been damaged - if so, solder a wire in its place and scrape out the lifted parts of the PC trace so they do not cause inadvertent shorts. If the voltage at the coaxial power jack also drops significantly, then your power supply or the power cable is at fault. 73, Don W3FPR On 10/27/2016 7:13 PM, David N. via Elecraft wrote: > Hello all my k2 has problem > Turn it on the s meter goes full up > 5 seconds later says low voltage shuts off. > I checked the display and the voltage is dropping and shut off at about 4.2 volts. > I checked at the power jack d10 and d12 and show the same thing but voltage at these points drop down to 9.4v on DVM then shuts off.

I did turn on my K3 connected to triband yagi and am seeing S5 noise "floor" where there are no signals (preamp off). Checking 6m I also see S5 but this is pointed at a local noise source and with ext Gasfet preamp on. If I turn the 6-element yagi 90-degrees the noise level drops to as low as S3 with preamp on (K3 needs some kind of preamp when using 6m). I also have the PR6-10 which I use on HF or 6m if I turn on DIGOUT-1 which energizes the PR6-10 and disconnects the ext preamp. It shows about one s-unit lower noise due to less gain than the Gasfet.

From there you can work out by how much (or how little!) you have to rotate the shaft per kHz of change. This will then dictate how you computer control your loop. Unfortunately you need to start at the other end of the project first and work backwards to find the right motor and gearbox. Transmitting loops with high Q can be fiddly to tune and then hold in tune, especially when they are only 3kHz wide. 73 Matthew VK5ZM On 28 October 2016 at 12:36, johnpierce wrote: > I have seen general definitions about motors for driving a capacitor in Mag > Loop.

In which case, HRD is probably sending some other command that changes DSP settings during transmit. You will probably need to document what commands HRD is generating in response to WSJT-X and work with Elecraft to determine which of those commands results in DSP changes. The 5.56 beta changes were in response to documentation of commands by Commander and another software package with the K3. I'd start with all commands from about 2 seconds before x:00 until x:05 since HRD is so unpredictable and commands could be delayed or out of order. *Any* application should know not to change things like split status, mode (including data sub-mode), sideband, transmit VFO, etc. while in transmit - whether directly or via an intermediary like Commander or HRD but, as we've seen, application programmers tend to be sloppy and not consider how the rig will react. 73, ...

Second, is your cap a butterfly cap. Those camps make a huge difference in performance. Although I have successfully used a double ganged cap with excellent results. Using a toroid to connect the loop with the turns on the toroid and the pipe going through the loop may be a better set up. Spacing on the coil turns and contact with the loop will change dramatically and I would highly recommend a faraday loop for feeding/driving the loop. make this coil/loop a circle with diameter 1/5 the diameter of the loop. For a 48 inch diameter loop that would be about 9.5 inches diameter. My loop worked great with a 1/4 inch copper tube 1/5 the diameter of the main loop fed directly across the coax, that is, braid on one side center on the other. I adjusted the matching by moving the loop up and down on the central axis. It worked great and would take 350 watts with out heating up, providing the resonant frequency of the loop was matched with the capacitor. My cap was rated at 2500 voltage break down. You might consider a gamma match with your loop, Although this will make the loop favor one side over the other but only marginally. Personally, I have never had much luck with just turns on wire on the loop to make it work. I know it is in the literature but it never worked repeatability for me because of the variability of the construct. I never used a 1to1 balun on any of my loops. And never got kissed by RF coming back at me. I could see that a wire wound choke balun may introduce inductance in the match and cause problems where as a bead balun may not cause problems. Also you are expecting way to much from this loop. Loops only work well for 1 maybe 2 bands at a time. This is limited by the variability of the capacitor and the inter capacitance of the construct. As you go up in frequency your need way way less capacitance and soon your loop will be unmatchable. Your 48 inch loop makes the conductor length of 12.5 feet. This is way big for 15 meters because it is greater than a 1/4 wave at that frequency and loops only function as a loop if they are a fraction of a quarter wave in frequency. You loop, if it is 48 inches in diameter is ideal for 30 and 20 meters and with the right capacitor will be usable on 40 with reasonable efficiency. A 2.5 foot diameter loop for the high bands is more in the ideal range for 20-10 meter operation. Because the total circumference of the loop is only 8 feet which is shorter than a 1/4 wave at the lowest frequency, 28 mhz. A loop this size will best work on 15-10 meters and will be matchable to work with decreased efficiency on 20. It calculates to about 48 % on 20 with all the other values much higher in efficiency as the frequency goes up. The Problem is with the matching capacitor minimum and maximum values and the intrinsic capacitance of the total system changing the resonance. Finding capacitors has always been the weak point in Loop construction. Vacuum variables with high Q values are the best widest frequency solution and can run the most power to the antenna because of their high voltage break down. The problem is the fragility and the cost factor of the capacitor. I shopped EBAY and found air variable double gang or butterfly caps that would work over a wide value of frequency for pennies compared to the dollars spent on vacuum variables, and for less than 100 watts, worked quite well.

Using two buttons (left&right) for control. Not that easy to fine-tune using an SWR-meter. Last year I switched to a stepper motor, bought controller hardware and developed a program in Visual Basic. Check my website for building info and free download. http://www.pa0kv.nl/magnetic_loop.html (see "part 2" for the stepper) Twan - PA0KV I have seen general definitions about motors for driving a capacitor in Mag Loop. But I have not seen a recommendation of a specific type to look for on Amazon or Ebay. For starters I am looking for a 12vdc reversible motor. I would like to start with a simple push button system for tuning. Maybe I will consider a stepper later. I think that would need some computer control. I am also wondering what RPM to consider for use on the lowest frequency (40mtrs). The capacitor I am expecting to use would not have a stop and could travel a full 360 degrees.

This unit is in mint condition and has never been used in a contest. It probably has about 30 hours of use, max. My original intent was to upgrade this K3 to a K3S, but this is not fully possible, given that all of the K3S upgrade boards have not been made available. Hence, I bit the bullet and went for broke! This K3 has been fully updated by the factory and currently "meets/exceeds factory specs." I had the original accessories migrated to the new K3S and the two units are presently en route to my home QTH, scheduled to arrive Tues. $1800 shipped and insured. 73, Ed NI6S From dave.phelps at gmail.com Sat Oct 29 12:32:52 2016 From: dave.phelps at gmail.com (Dave) Date: Sat, 29 Oct 2016 11:32:52 -0500 Subject: [Elecraft] KX3 & RMS Express - T R latency Message-ID: Howdy, I'm using an old laptop to connect my KX3 to winlink system.

K3/K3S is not powered up and online, you?ll get a warning signal. This means that the mini is not ?seeing? the host transceiver. Power up the K3/K3S and see if that doesn?t resolve the issue. If you?re still having issues, then check your cables for proper connection and that you indeed have internet between the K3-Mini site and the K3/K3S.

I'm assuming when you say RRC you mean the MicroHAM RemoteRig Control system - I've helped set these up and test them for a couple of years now, so assuming I've got that bit right... It simply means that it's unable to talk to the other end (ie the kit you haven't connected at the far end). The MicroHAM RRC systems use SIP over UDP on three different ports - one for voice data, one for CAT data, and one for control signals between the remote head and the unit body. If it's a SIP connection error you're seeing, it's because the two ends of the RRC system can't see each other (which, as you say, is the correct case because you haven't hooked up the remote unit yet). If I'm barking up the wrong tree, please correct me. 73, and a firm left handshake, John (XLX) -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Cary Sent: 29 October 2016 22:27 To: elecraft at mailman.qth.net Subject: [Elecraft] K3 Mini Error question I just packed up both my control and remote systems and moved them down to my ZF QTH, where they will be permanent.

All fine as your remote is not connected yet. ;-) SIP is the Session Initiation Protocol, basically the standard to initiate a digital phone contact (the RRC's are using exactly that, an VoIP connection). 73, Olli - DH8BQA (SOSB10 in CQWW thus time to answer, hihi) Contest, DX & radio projects: http://www.dh8bqa.de Am 29.10.2016 um 23:26 schrieb Jim Cary: > I just packed up both my control and remote systems and moved them down to my ZF QTH, where they will be permanent. > > I have the K3 mini hooked up to the control RRC unit, but haven?t hooked up the remote unit yet/ > > When I powered up the mini, and turned the volume control I got a three tone warning signal.

See the DATA MODES section in the manual for more detailed information, but "in brief": PSK D does not respond to audio, but only to input from the paddles (in CW which is converted to PSK signals) or from ASCII text sent over the CAT cable. You did not say what you have connected on the other end of those cables, and that is an important piece of information. If you have a soundcard connected to the other end of the cables, you must use DATA A submode (or AFSK A for RTTY). Again, see the DATA MODES section of the manual. Since those cables have TRS plugs (and not TRRS plugs), you may have to turn off MIC BTN and MIC BIAS in the KX3 menu. 73, Don W3FPR On 10/29/2016 6:25 PM, David Inger wrote: > I decided to get my new (to me) KX3 going on psk31.

My notes were a little incomplete. So, I embarked on a few tests to narrow down the proper KX3 settings. Don had the right advice for you - the secret sauce is the Data A mode. The Mic Btn menu item can be set to anything. An additional observation is that the mic bias and mic btn menu items will not be available to change their values when in Data A. Mind you though, I also had the Mic Btn set to just PTT (as Bill suggested) from a couple of years ago. But, today's tests showed me scanning would happen regardless of the Mic Btn value. FYI...I have the latest firmware on the KX3 (non-beta). I did a few tests to prove my theory. Data A being set for any external sound card hookup yielded no scanning. If the 'D' data modes were selected, unplugging and plugging the mic cable (green), would result in a short scan and then stop. I tried various values of mic bias and mic btn and all had the same scanning effect when not in Data A mode. regards, Brian VE3IBW On Sat, Oct 29, 2016 at 8:28 PM, Nr4c wrote: > From menu turn OFF Buttons. > > Sent from my iPhone > ...nr4c. bill > > > > On Oct 29, 2016, at 6:25 PM, David Inger > wrote: > > > > I decided to get my new (to me) KX3 going on psk31.

When you tune, much more power is used. I have a 160m antenna and never have an issue if I run below 100W. The minute it gets to 110, I have the same issues as you. I suggest turning down the tune power as a test.

A converter box made by Frederick Electronics converted the RTTY Baudot code to Morse. However, we did have an old 2-hole CW tape machine that was used for the frequency-measuring tests because you could send long dashes with it by manually covering up the "off" hole at the end of a dot or dash. I don't remember what brand of machine it was. You might consider donating your "find" to the ARRL museum.

However, it now has a problem tuning my 160M dipole for no obvious reason. Symptoms are continuous searching for a match. If it finds a match in tune mode, ?as soon as you hit the key, ?it begins tuning again in "Auto" mode or faults in "MAN" mode, regardless of power level. ? What is interesting is that the KAT500 will tune my OCF Windom on 160M with no problem. Initially assuming it was the antenna at fault, I did the follow checks. - Checked the 160M dipole with an Antenna Analyzer and both it and the coax check out fine. Even where the analyzer ? ?suggests a 1:1 match, the KAT500 tries to retune.?- Switched input ports on the back of the KAT500. No change. - Used the K3 ATU (with KAT500 in bypass mode and with the dipole directly connected to the K3) and it matches the ? 160M ?dipole antenna with no trouble.?- Erased all the previous 160M tune memories, no change.- Reset factory defaults, no change.- Reloaded the firmware from the website, no change. ?

I took my extra code exam with a portable version of this machine, run by the FCC examiner. It's a long story which I won't repeat, but it involved a tape machine malfunction! Cranky beasts.

Note that this will erase any settings such as FN keys etc that you have programmed, so you may want to save the configuration with P3 Utility or write them down. To perform the parameter reset, turn off the P3 and then while holding down the MENU key, press the POWER key. If the parameter reset doesn't fix it, please contact Elecraft Customer Service via phone or email. Their email is k3support at you know where dot com. 73, Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-wonky-on-30-meters-tp7623700p7623755.html Sent from the Elecraft mailing list archive at Nabble.com.

Instruct-O-Graph sounds familiar. My ham license instructor (elmer) used one in night-time class a nearby HS (Caro, MI). He was music teacher for his day job. Must have trusted me as he let me take it home after class ended. I got to where I had memorized the tape after playing it, so resorted to copying code with my 3-tube regen receiver on 40m. He administered my Novice exam resulting in KN8MWA in Nov. 1958.

I've always had it OFF-OFF. Apparently during or after our move to NV, probably while setting up the gear in the new "shack", it got changed to DTR-OFF [obviously by me, who else?]. There are no radio programs or loggers running on the computer but it is an RS232-USB adapter. Thanks to all who suggested the solution. 73, Fred K6DGW - Sparks NV DM09dn - Northern California Contest Club - CU in the Cal QSO Party 7-8 Oct 2017 - www.cqp.org
