I'm wondering about adding a KXPA100 into the mix. I think that KXPACBL provides the necessary connector breakouts for me to keep the modified MFJ-1707 here with the KX3, whilst installing the linear remotely, connected by CAT6 and coax. The MFJ-1707 will switch between the receive loop and the linear's RF input. I'm hoping that the keyline and ACC2 IO ports connected to the MFJ-1707 will function as they did before the KXPA100 was installed. I will use a computer adjacent to the linear to provide CAT remote control facilities (with Hamlib's rigctld) to the computer adjacent to the KX3. Is this notion consistent with reality?

If you are the kind of guy who will sit down with the manual and read every page and simultaneously perform functions on the rig then you don't really need the nifty books. Depending on how much you use your rig you will learn everything you need to know eventually. This may be 4 hours for some users and 4 months for others. After that you rarely ever have to refer to the printed manual. However, it's a good idea to keep the latest PDF version of the manual on your PC. This is very handy since you can search for words. 73, Mike K2MK Mike Zbrozek wrote > partial quote: > > I was wondering if its worth the added cost to purchase the fol: > Nifty Ham Accessories - K3 plus options. > Elecraft P3 Pan Adapter - Mini Manual Op Guide. > > As you know the K3 comes with a Op book.

The forecast is for snow this evening into tomorrow. I knew there was a chance for snow when I saw the daffodils sprouting. They really should wait a few more weeks. The sun has been fairly unspeckled recently but the SFU is still above 100. I was unable to test propagation this week due to a lot of computer work. But, hopefully things will be much like last week's fine nets. We did discuss whether we would want to live in or near Boston this year. Record snowfalls are great when school is cancelled but once you graduate all you can think about is digging out and driving in it.

The last check is to measure resistance across the 12V terminals to make sure its not a dead short. The documentation says it should be over 2000 ohms, but I measure open circuit. Can someone check for me what they see across 12V terminals on a regular working K3? This is probably a pretty stupid question but since I didn't build this K3 I'm not sure what to expect.

Meanwhile, "fixed-tune" mode became the obvious priority based on a survey of list comments, so our available PX3 firmware engineer switched gears and has been working on that. Fixed-tune is now on its second in-house release, and we'll probably be sending another update out to some PX3 users who gave us the first round of feedback. We will then return to the keyboard driver. There is probably some corollary to Murphy's law that goes something like, "Everything is harder than you think, and takes longer than you estimate." (Nevertheless, we persist. For example, the K3 is on its five hundred fourteenth firmware release.) 73, Wayne N6KR On Feb 28, 2015, at 4:40 PM, Josh Walton wrote: > We are close to entering into the second quarter of 2015.

It shows that I have a peak at 500 Hz, which correlates pretty well with my preferring a CW pitch of about 550. The site has, however, two recognized sources of error. One is that it can?t correct for peculiarities in the response curve of the headset used. The other is that the pitch change itself creates a subjective sense of impact. It showed that I have a second peak at around 3 Khz, which seems physiologically unlikely. Tones that high I find annoying, like chalk screeching on a blackboard, which may be the subjective equivalent of loud. The other side of the QSO equation is what tone frequency will best get you through the QRM. I wonder where most people who are listening to me (and a pileup of others) have their filters peaking? By listening to whom and where the DX is working as the pileup goes on we can infer the operator?s tuning habits and be on the next expected spot, but not all of them behave in discernible ways. If the target station seems to be listening at the same spot through multiple QSOs (as in contests), is it better to split (or XIT) and transmit up a touch first, or down, and by how much? Anyone know where the CW response peak of the ham population (or of its receivers) lies?

If I turn the power control up, the display defaults back to 8 watts.? In the config menu I have the tune power set to 20 watts. I reloaded the firmware to make sure there wasn't a glitch in the loading.? The same problem still occurs. The only other troubleshooting I did was to change the TX ALC (in the config menu) to "OFF"?

Message-ID: While in the NAQP RTTY contest this weekend, I noticed that on 80 meters the passband is centered on the indicator of the P3 and not off to one side (left or right depending on which side band I am using). Anyone else have this? Is there something I need to adjust?

I was member of the church choir. I play classical guitar...and never got better than 12wpm copying CW. But my musical background likely made sending easy (18-20wpm with straight key). So goes another "urban myth". Of course if I could have held my Novice longer than one year that might have helped vs getting a tech license and being banned to 6m-up which was mainly AM way back then. More likely was due to my initial interest in voice vs CW. After three years of failed CW exams at the FCC office (long before VE program or multiple-guess code tests - one minute perfect copy of five character groups of random text/punctuation/numbers). We lived 5 miles too close to take the Conditional license. But I passed in 1982 (24-years later) before the FCC at the Anchorage Office because I wanted to go out on the Iditarod Trail as a ham radio checkpoint volunteer. Comms were on 80/40m SSB so you had to have a General License. CW test made much easier to pass in 1982 with real text and multiple-choice testing on content. I also took and passed my Advanced in same sitting. Passed Extra in 2000 when code requirement was dropped to 13wpm. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From kl7uw at acsalaska.net Sun Mar 1 17:28:46 2015 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sun, 01 Mar 2015 13:28:46 -0900 Subject: [Elecraft] CW listening pitch Message-ID: <201503012228.t21MSlRt052154@huffman.acsalaska.net> These days my ear is perfectly tuned to 1000-Hz.

I could have passed the Extra with CW speed to spare except that back then you had to have 2 years of on-air experience before you could sit for it. I can still copy the W1AW 35 WPM on a keyboard. Age however has restricted my hand sending to somewhere between 25 and 30. Beginning in college, I tried to learn to play the piano, and continued for the next 50 years. Operative word in that sentence is "tried." We have an old piano. My wife insisted that I "practice" only when she was gone. When the kids were little, I took some guitar lessons. I learned one song ... "Little White Duck" which they sang as I played -- slowly. Apparently, the Urban Myth is symmetric ... skill with Morse does not always correlate with musical talent either. For what it is worth, the best pitch for someone may not be right at the peak in their hearing. It definitely isn't for me. My hearing was severely damaged many years ago and the peak for me is around 400 Hz. I'm basically deaf above about 1200 Hz, my hearing aids are at afterburner roar up there. Best CW pitch for me however is 570 Hz. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/1/2015 2:22 PM, Edward R Cole wrote: > I played in the school band from 5th grade thru 12th (played clarinet > and oboe).

I hated it and quit shortly after. In hindsight (20-20) I wish I would have stayed with it. In high school a friend was a drummer in the band. He wanted to take up sax but the *hole director wouldn't let him because he needed drummers for the marching band. My buddy convinced me to become a drummer so he could take up sax. Of course, you don't need to read much music to play snare drum in a marching band so my skill was limited. although I did play timpani in the orchestra so I read (past tense) a little. I was interested in radio even before high school so when I got there I met a guy who had been a (lapsed) Novice and learned a little more about it. We formed a radio club and since the principal was a Lt. Cmdr in the Navy reserve and CO of the local center, the faculty advisor was able to tape record the Navy's code practice records. The club would meet only once a week to practice code. Needless to say this wasn't often enough and we would start from the beginning meeting after meeting. I grew tired of this and wound up learning the code by sight from my 1954 Boy Scout Handbook (I still have it). As a consequence I never became proficient. I took my Novice and then Conditional exams from a neighbor (W7UVR sk). All was good for some time. I became interested in weak signal VHF work and got into 2-meter tropo and meteor scatter. Schedules were set up on the Central States VHF Society net on the high end of 75-meters. At some point it was decided for QRM reasons to relocate the net to the Advanced Class part of the band. Uh oh, "incentive licensing" reared its head and I needed to upgrade. The next time the RI came to town I was ready to take the Advanced exam. Since I had credit for 13 WPM already I didn't have to take the code test and didn't practice. After passing the exam I asked the examiner whether I could try the Extra. He said, sure sit over there, the test will start in a few minutes. When the test began I completely choked. I wadded up my paper and threw it in the trash. The examiner said that he needed to see it anyway. He was very kind and said something like, "I'm afraid I can't get much out of this." I was humiliated and vowed to pass the exam the next time the FCC came to town., which I did. But I'm still neither a musician or a fast CW man.

PSK D and FSK D do not use VOX and will show N/A if you try to turn it on.

This was hastily assembled after the audio interface arrived Saturday. Things came together splendidly whereupon I made QSOs with west coast stations from Virginia. Only after the contest did I realize I was a bit too conservative with the output power. I set the interface's audio transmit pot to yield not 4, not 3, not 2, not 1, but ZERO ALC bars. I did confirm transmit using a separate receiver and, of course, the contacts I made were quick, simple and productive. I saw it worked so just forgot about the ALC settings. I read in the manual the suggestion to adjust audio-in to yield about 4 bars ALC. My radio power was set to 5 watts. Question: Is there a chart of graph I've somehow missed relating ALC bars to the percentage of power output setting? Thanks.

VOX is active in AFSK-A and DATA-A modes. I've never used anything else for data modes. The sound card drives the Line Input, and it is usually necessary to adjust VOX gain and Line Input gain. 73, Jim K9YC From k3ndm at comcast.net Mon Mar 2 00:34:19 2015 From: k3ndm at comcast.net (k3ndm at comcast.net) Date: Mon, 2 Mar 2015 05:34:19 +0000 (UTC) Subject: [Elecraft] KX3 - Power out vs. ALC bars In-Reply-To: <54F3F161.3050206@hamradio.me> References: <54F3F161.3050206@hamradio.me> Message-ID: <1984730332.4149006.1425274459100.JavaMail.zimbra@comcast.net> John, The manual states that you should keep the ALC bars in the not to exceed 5 range.

I suspect that your Icom is rated at 100 Watts peak. Meaning you need to adjust the input to keep the level down to 1/4-1/3 the rated output. And, you may have need to back down on the input auto further so as to not generate too much ALC action. This satisfied two problems, distortion and over heating of the finals. The rules are the same for the KX3, keep distortion low and don't over heat the final. Elecraft says not to kick up too many bars for ALC. That's for distortion. Use the power control to keep your power down to the 100% duty cycle level. Your audio input controls the ALC. I don't have my manual handy, but I can say it is covered there. 73, Barry K3NDM ----- Original Message ----- From: "John" To: k3ndm at comcast.net Cc: "elecraft" Sent: Monday, March 2, 2015 12:44:07 AM Subject: Re: [Elecraft] KX3 - Power out vs. ALC bars Is it safe to say my very low input audio level was compensated by the KX3's power control loop to yield 5 watts out (the actual radio power setting)?

In order to make his manuals truly useful, Fred had to give the content a lot of thought, and do all he could to make them truly justifiable as an accessory. I think he has done that! Fred seems to have an exceptional "knack" for organization and strong content. I have Fred's manuals for both my K3 and my KX3, and I use them regularly.

The Omni VII manual seems to be decent, but I think it is rather "skinny", at least compared to Elecraft's manuals. Anyway, that was my perception. Also, I've had some Yaesu radios in the past where the manuals were fairly substantive, but the radios themselves were excessively complicated (in my opinion) with all the necessity to dig deeply into menus for regularly required changes. Now, all modern radios seem to require a lot of menu adjustments in order to deal with the plethora of features contained therein, but I personally feel that Wayne and Eric gave a lot of forethought to accommodating a lot of features plus ease of access to those features. If you will take the time to become as fully familiar as possible with each control on an Elecraft radio, and what all it will do, you will go a long way to making your life easier. Many/most of the menu items on Elecraft radios are "set them once and forget them" type items, if you even need to do anything! Almost all of the common adjustments are right there on the front panel! In any event, the complexity of most modern radios almost necessitates that we get all the help we can to properly use them. So, well organized 3rd party offerings are probably a good thing most of the time, but some are better than others.

In general, we humans hear logarithmically. Also, we hear differences in sounds that are separated by some "critical bandwidth" that is in the range of 1/3 to 1/6 of an octave. An octave is a 2:1 frequency ratio. So figure 2 to the 1/3 power and 2 to the 1/6 power. I set my radios between 500 - 550 Hz. Those with severe high frequency hearing loss might want to try even lower frequency settings. Most (but definitely not all) hearing loss is greatest at the higher frequencies. 73, Jim K9YC From k2av.guy at gmail.com Mon Mar 2 03:31:39 2015 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Mon, 2 Mar 2015 03:31:39 -0500 Subject: [Elecraft] New K3 Syn In-Reply-To: References: Message-ID: One thing that people need to remember when making a purchase decision on K3 upgrades, is that in the future, wanting to sell a K3, one of the first questions will be whether the rig has the newer synthesizer(s). For me, without, that would be a $300 derating for single RX and a $600 derating for the old boards. Cost plus inconvenience to bring it up to spec. It's like selling a K3 that has only a few of the mods, and particularly not having the new audio board. Someone buys it and immediately sends it back to the factory to be brought up to date, if they buy it. And then of course there are the "unintended" positive side benefits of an upgrade, like the much clearer audio when the AGC significant digit problem was fixed. Don't know what they are this time around, but I'm sure there are some. Beyond that, there is the profit angle, where a small percentage of total rig value is invested to bring it up to date, avoiding a new rig purchase to obtain same. Your purchase of upgrade materials rewards that business strategy and helps insure they keep doing business that way. If that were not enough, it maintains the reputation of a rig as not becoming obsolete, vastly improving its resale value. Seven year old radio, as modified, still at the top of the heap. Just how good is that. And still more, that means that any new Elecraft rig will build on top of proven CURRENT firmware and hardware knowledge, there because there were customer purchases to support it. The KX3 is a very clear example of that. Yeah it's certainly YOUR pocketbook and not mine, but hanging back is short term strategy and what I'm talking about is long term strategy. Don't lose sight of the long term. Support your radio manufacturer. 73, Guy K2AV On Sat, Feb 28, 2015 at 10:17 AM, drewko wrote: > Not a bad idea...

You now *own* your K3 in a special way that the factory-built model can never offer. One of the things we do when building a K3 is to 'train' all the connector pins to mate more easily with each other. We also train ourselves, so it really does become easier next time. This applies especially to the front panel because there are so many connector pins. I'd hate to think that anyone has assembled the front panel once but has then declared "Never again!" Next time, it will genuinely be MUCH easier. 73 from Ian GM3SEK From w3fpr at embarqmail.com Mon Mar 2 06:47:31 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Mon, 02 Mar 2015 06:47:31 -0500 Subject: [Elecraft] KX3 - Power out vs. ALC bars In-Reply-To: <54F3F8A7.3080705@hamradio.me> References: <54F3F161.3050206@hamradio.me> <1984730332.4149006.1425274459100.JavaMail.zimbra@comcast.net> <54F3F8A7.3080705@hamradio.me> Message-ID: <54F44DD3.6000102@embarqmail.com> John, The KX3 (or the K3 or K2) will not control its power output properly unless you drive the audio sufficiently. The "ALC meter" on the K3 and KX3 is a combination of an audio level meter and ALC meter. Below 5 bars indicated is really the 'no ALC' range. So adjust the soundcard audio and/or the KX3 mic gain to produce 4 bars on the ALC meter. After doing that, adjust to the desired power with the power knob. Remember that the KX3 will attempt to maintain the power level requested, so if your audio level is too low, the power control will become erratic and creep up and down. What I am saying is that attempting to control the power output with the audio level will not result in proper operation. 73, Don W3FPR On 3/2/2015 12:44 AM, John wrote: > Is it safe to say my very low input audio level was compensated by the > KX3's power control loop to yield 5 watts out (the actual radio power > setting)? > > It's hard to shake my Icom digital interface habits. > > Thanks. > John, kx4o > > On 3/2/2015 12:34 AM, k3ndm at comcast.net wrote: >> John, >> The manual states that you should keep the ALC bars in the not >> to exceed 5 range.

When you use two K1EL Winkeyers connected over IP you have additional latency because the local winkeyer is decided before the character is sent over IP. The major contribution to latency is the internet, and it is not constant. 73, Jim K9YC From andy.nehan at btinternet.com Mon Mar 2 07:59:40 2015 From: andy.nehan at btinternet.com (ANDY NEHAN) Date: Mon, 2 Mar 2015 12:59:40 +0000 (GMT) Subject: [Elecraft] Gearmo 4port USB to Serial Message-ID: <14523659.43586.1425301180606.JavaMail.defaultUser@defaultHost> A couple of months ago I saw someone recommend one of these (available through Amazon).

I am printing that one out and studying it carefully. One aspect of the listening tone frequency has been zerobeating a station. The K3 is the first time in my 52 years operating CW when I could actually do something about it instead of just trying to tune by ear to what I thought was probably about right. My ability to get that right was not very good at 700 Hz. That CWT is the greatest thing since sliced bread! As for tone frequency, I was initially trying to copy at 700 Hz and wondering why I was not doing as well as expected in the ARRL DX CW last weekend. I dropped it to 600 Hz and will experiment this week with 550 Hz and 500 Hz. My thanks to everybody on the Elecraft Reflector.

About 15 to 20 years ago, myself and maybe some 15 other USA hams got into QSO'ing at QRQ. (In my opinion, QRQ is anything over about 60 wpm) I had served in the Navy for 11 years, with six of those years spent on Navy aircraft carriers, mainly in the Gulf of Tonkin. Our berthing spaces were always immediately below the flight deck, toward the rear of the carrier; in other words about ten feet below where Navy aircraft were landing on the steel deck. My 'normal' hearing suffered greatly! When operating QRQ, sometimes with QSO's at around 120 wpm, but mostly >80 wpm, I found that a pitch frequency of about 520 hz was best for me; however as the years wore on, I found going down to around 480 hz was much better (as my hearing continued to decrease due to age!). Now, at age 76, I finally had hearing test done and found my hearing peaks at 375 hz, and 1 kc and 185 hz is 12 dB below that. The so-called "advantage" of this is that our hearing now also acts as filters for atmospheric static noise above about 800 hz. I think that as we age, all of us lose most of the high frequency audio spectrum and the typical manufacturer's classic sidetone frequency of 700 hz is seldom optimum for the 'over 45' age group. Still, IMO, the 'best' CW pitch is only determined by the individual. 73, Tom - W4BQF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Sverre Holm (LA3ZA) Sent: Sunday, March 1, 2015 10:33 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] CW listening pitch There is evidence that it is advantageous with a low tone for the pitch (asuming normal hearing).

IMO, the upgrade synthesizer is supposed to be an improvement if 1) you need better full CW QSK, and 2) if you need to copy very weak close-in CW signals in the presence of S9+ signals and/or if you do a lot of contesting. The basic K3 handles both of these criteria pretty well, comparatively speaking (look at the Sherwood data), and the quoted '$600' difference is strictly a user's option. I just sold my five year old K3 with the understanding that I was selling the buyer a darned good radio (that did not have the new upgrades) and I don't think the buyer was short-changed at all.

Once I'd gone through my modified version of Wayne's process for adjusting the VCO (i.e. adjusting the VFO to have the WWV 100Hz sub-carrier on 100Hz), I realised that this applied only to LSB FIL1. As soon as I switched to FIL2, the sub-carrier moved and I needed to use CAL FIL to adjust it back. Also, if you want to move the position of the filter in the audio spectrum (e.g. to change where the skirts are), and thus change the BFO; you need to run Wayne's process again.

I have no real knowledge of why low tones seem to make for better copy in QRM but I have guessed that it has to do with the relative difference in interfering tone for a given offset from the desired signal. If you listen to 1000 Hz (which many ops do) and the interfering signal is 100 Hz away, the difference is only 10%. But if you listen to 400 Hz, the difference is 25%. So the filter in your brain may be more effective distinguishing 400 from 500 Hz than it is in distinguishing 1000 from 1100 Hz.

The latency between the two keyers is a variable (depending on the locations of the two keyers), but the K1EL keyer latency should be some standard latency times two. Any idea how much that standard keyer latency would be? I'm interested in adding up the latency contribution from the basic components to understand how each part contributes to the total latency. I'll initially be most interested in voice, but then in CW and perhaps eventually in RTTY. This is mostly a thought exercise at the moment. There is a kickstarter going for an audio interface with less than 3 millisecond internal latency. It is designed for internet music jam sessions. My current equipment (including a router) seems to have about 18 ms latency and a total latency between two players seems to need to be less than about 25-30 ms for two or more to play together across the internet. So add internet latency and can't play with folks outside the West Coast. This all got me thinking about remoting radio and whether there might be a dual use for this "Jam Blaster".

If you presume that indeed you plan to sell the rig in a couple of years and that best way to sell a rig in the future is to have it "current" when you place it on the market, then presumably that means purchasing upgrades prior to placing it on the market. The question then becomes "buy the upgrade now or buy later?" The answer depends upon how you view the benefits of the upgrades: 1. Buy it now before potential prices increases later for those upgrades. There is no guarantee that today's prices will remain unchanged (labor, materials and other costs of production do change) so this is an assumption that the likelihood is that prices will go probably go up. 2. Recognize that the future value of the radio may be enhanced by adding the upgrade, but the "net value" of that rig will likely not increase as much as the cost of the upgrade. "Depreciation" coupled with the recognition that there is likely no warranty carry forward if the upgrade is installed by the prior seller means that the value to the buyer is less than what you paid for it. In other words, you'll get more for the rig, but the numbers may not offset the cost of the upgrade itself. 3. If you're going to install the upgrade at some point in the future anyway and you can afford to pay for it now, why not do the upgrade sooner rather than later? That way you'll also gain the benefit of the improvement for the remaining time that you own that rig, offsetting to some degree the "cost" of that upgrade through the enjoyment of those enhancements. This rationale is similar to your comment about making the purchase because you want the benefit of the upgrade. I'm adding to that sentiment by suggesting that if the purchase will definitely be made at some point, it is better to do so sooner rather than later so that you can benefit from it as well. 4. After using the enhancements it may be conceivable that the capabilities of the "new rig" may preclude the desire to sell it, thus avoiding the pain and suffering of placing it on the market in the first place and then going through the process of deciding what to get next. 5. Even if we decide not to do the upgrades and later sell the rig, the relative value of the "base case" is likely enhanced versus other products because the buyer has the option to add the enhancements. The rig is not locked into only those capabilities that existed at the time of production. The same approach should be considered in other major transactions. For example, if you know that you'l be selling your home in 3-5 years and recognize that some enhancements are needed to improve the marketability, why not do the upgrades sooner rather than just before placing the home on the market? That way you'll have the opportunity to enjoy the enhancements plus costs never go down, they always go up. Lock-in those costs earlier and not pay more later. Heck, you may decide after doing the enhancements to not sell after all, which is probably cheaper than going through the pain and suffering of selling one home, buying another, and then getting the new home setup the way you want it. Of course such decisions in amateur radio or other aspects of life are not always based on "logic" or economics. And each person has a different interpretation of cost vs. benefit, thus driving different decisions. I think we can all agree, however, that having Elecraft provide improvements to their products through both firmware and hardware updates is generally a good thing and that the marginal cost of these improvements has been less than purchasing a brand new comparable rig from Elecraft or someone else's product.

The latency (the time from when you send a character from Your paddle to the local PC until the remote rig starts to transmit this character) will be about half a second (500 milliseconds!) plus the internet delay. My understanding is that this delay at least partly is caused by the decoding of the paddle input. I did not measure this but I have used two connected Winkeyers for some time and that is my experience. When you use the keyboard as an input to the local winkeyer it corresponds to using a paddle input with very fast keying. In both cases (paddle or keyboard) you can input so fast that you constantly are a little ahead of the transmitted stream. That in fact is necessary for perfect CW. Therefore, break-in CW is a little easier using the keyboard rather than the paddle. However this only applies to a system based on local decoding (Winkeyer). The Remoterig system may be better in this respect- I have no experience with Remoterig. Of course if you have a poor internet quality (high latency or high jitter) this might be the limiting factor. Remote operation is no fun with bad internet quality! But you can definitely make fine CW QSOs even over a satellite link (ping time 600 msec). High latency is not too much of a problem - you can get used to it (in my view after using remote CW for ten years). But high jitter is a PITA. If you have a good internet quality (say latency around 30-50 msec) you will feel annoyed by the "buffer" latency, especially if you try to operate break-in using paddles. You will need to be prepared to stop transmission (cursor placed over the stop button in the Winkeyer window ready for you to left-click in order to stop immediately). This IS possible but NOT easy to do. Sendt fra min iPad > Den 02/03/2015 kl. 18.50 skrev "Rich" : > > Paul, thanks.

It is a design compromise, not much you can do about it. If you adjust the reference oscillator, eg. by using Wayne?s procedure, then you need to run the CAL PLL and CAL FIL procedures again to update the firmware parameters. So, if you modify the filter settings such as the skirt positions, don?t run Wayne?s process again, or you?ll need to repeat the CAL PLL/CAL FIL procedures. --? 73 de Matt VK2RQ On 3 March 2015 at 3:11:58 am, Gareth - M5KVK (m5kvk at m5kvk.org) wrote: I realise this is close to becoming an obsession, but I really want to understand what's going on. Once I'd gone through my modified version of Wayne's process for adjusting the VCO (i.e. adjusting the VFO to have the WWV 100Hz sub-carrier on 100Hz), I realised that this applied only to LSB FIL1. As soon as I switched to FIL2, the sub-carrier moved and I needed to use CAL FIL to adjust it back. Also, if you want to move the position of the filter in the audio spectrum (e.g. to change where the skirts are), and thus change the BFO; you need to run Wayne's process again.

Install went very easy even without a cat (or in my case a dog) on my lap. I am pretty much a SSB and Digi operator. I did tune around a bit looking for a couple of SSB signals that were right on top of each other to see if I could hear any difference from before. My impression is that my K3 is quieter over all (almost urban environment with a lot of RFI), and I felt that I could more easily copy one signal over another closely spaced signal. I didn't seem to hear that rumble from another station even though it was only a few KCs away. Does this make sense?

So adding options and or upgrades is hardly going to enhance the radio value by more than the cost of the option or upgrade. It is probably the case that a basic 100 Watt K3 is the easiest K3 for which to find a purchaser and thus maybe the radio which recoups the greatest percentage of the purchase price. Not having the SYN board would not significantly affect my decision to purchase. It could always be added later. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Chester Alderman Sent: 02 March 2015 14:40 To: 'Charlie T, K3ICH'; elecraft at mailman.qth.net Subject: Re: [Elecraft] New K3 Syn Hmmmm...I don't quite agree with Guy's assessment of the upgrades. IMO, the upgrade synthesizer is supposed to be an improvement if 1) you need better full CW QSK, and 2) if you need to copy very weak close-in CW signals in the presence of S9+ signals and/or if you do a lot of contesting. The basic K3 handles both of these criteria pretty well, comparatively speaking (look at the Sherwood data), and the quoted '$600' difference is strictly a user's option. I just sold my five year old K3 with the understanding that I was selling the buyer a darned good radio (that did not have the new upgrades) and I don't think the buyer was short-changed at all.

I've read the K3 specs and t he way I interpret them, the typo is on pg 8 and should read 20 kHz. I'd like someone to verify I'm not going off in a wrong direction here.

Recognize that the future value of the radio may be enhanced by adding the upgrade, but the "net value" of that rig will likely not increase as much as the cost of the upgrade. "Depreciation" coupled with the recognition that there is likely no warranty carry forward if the upgrade is installed by the prior seller means that the value to the buyer is less than what you paid for it.

If you're going to install the upgrade at some point in the future anyway and you can afford to pay for it now, why not do the upgrade sooner rather than later? That way you'll also gain the benefit of the improvement for the remaining time that you own that rig, offsetting to some degree the "cost" of that upgrade through the enjoyment of those enhancements. This rationale is similar to your comment about making the purchase because you want the benefit of the upgrade. I'm adding to that sentiment by suggesting that if the purchase will definitely be made at some point, it is better to do so sooner rather than later so that you can benefit from it as well. > > 4. After using the enhancements it may be conceivable that the capabilities of the "new rig" may preclude the desire to sell it, thus avoiding the pain and suffering of placing it on the market in the first place and then going through the process of deciding what to get next. > > 5. Even if we decide not to do the upgrades and later sell the rig, the relative value of the "base case" is likely enhanced versus other products because the buyer has the option to add the enhancements.

For example, if you know that you'l be selling your home in 3-5 years and recognize that some enhancements are needed to improve the marketability, why not do the upgrades sooner rather than just before placing the home on the market? That way you'll have the opportunity to enjoy the enhancements plus costs never go down, they always go up. Lock-in those costs earlier and not pay more later.

This in turn noticeably improves the K3's top performing close spaced Rx dynamic range, yielding even better weak signal detection in the presence of strong signals. FASTER CW BREAK-IN AND MORE ACCURATE CW ELEMENT TIMING EXCELLENT MECHANICAL STABILITY The KSYN3A is virtually immune to both physical vibration and magnetic coupling, and operates over a very wide temperature range. 600-METER COVERAGE The KSYN3A extends VFO tuning down to 100 kHz, with sensitivity gradually falling off below 450 kHz. Transmit output is as high as 1.0 mW for use with a suitable external amplifier. (Note: 600-m and below operation also requires the KBPF3 and KXV3 options.) wunder K6WRU CM87wj http://observer.wunderwood.org/ On Mar 2, 2015, at 6:02 PM, James D.

You must do things in order and all will work out properly. First, the 100 Hz WWV subcarrier should be outside the passband of the SSB filters, so it will have a very low amplitude. It is better to use the alternating 500 and 600 Hz as well as the 'on the minute' tone at 1000Hz to determine the correct tuning of WWV. The tone at 2 minutes after the hour is 440Hz. If your SSB OP1 (or FL1 if no KSB2) filter passbands are not properly aligned, do an initial alignment of the LSB and USB filters so the filter passband low frequency slope -5dB point is at 300 Hz (use Spectrogram to observe the passband position). Once the SSB FL1 filter is adjusted, then receive WWV and use the Spectrogram (or other audio spectrum analyzer) to properly tune the WWV transmitted tones. Once tuned properly, lock the VFO to prevent moving the VFO knob. With WWV properly tuned, set to CAL FCTR and alternate the internal counter probe between TP2 and TP1 while adjusting Control Board C22. Since all WWV transmissions are on '000.000 kHz boundaries, all you need to do is observe the 4 low order digits in the CAL FCTR display and you do not have to do the subtraction in every case. Once C22 is properly adjusted, put the counter probe in TP1 and run CAL PLL. When CAL PLL finishes, then go to CAL FIL. Even though the FL1 passband has been previously set, you must still change the BFO settings. Move them up one DAC count and back down to where they were before. Then adjust the BFOs for SSB FL2 thru FL4. I set the low frequency slope of FL2 at 350Hz, FL3 at 400Hz, and FL4 at 500Hz. Adjust the BFOs for the CW filters (and RTTY filters if you have them enabled) to properly position the filter passbands. If they were set correctly before, move them by one DAC step and back again - this is to force the BFO frequencies to be recorded into EEPROM with the current 4MHz reference frequency. After those steps, re-check the WWV tuning. It should be correct within 20 Hz. The BFO DAC steps are approximately 20 Hz wide, so you may see a shift in the tuning by that amount. If it is greater than 20 Hz, re-do the entire procedure from the beginning. I do this procedure more than 3 times a week on K2 repairs, and it always works. 73, Don W3FPR On 3/2/2015 11:11 AM, Gareth - M5KVK wrote: > I realise this is close to becoming an obsession, but I really want to > understand what's going on. > > Once I'd gone through my modified version of Wayne's process for adjusting > the VCO (i.e. adjusting the VFO to have the WWV 100Hz sub-carrier on > 100Hz), I realised that this applied only to LSB FIL1.

This is due to a change in the way the receivers are driven by the synths. In diversity mode, as long as the main and sub crystal filter offsets are matched, both receivers are driven by the main synth (the sub synth is not used in this case). So, when the VFO is moved, the local oscillator phase relationship remains stable between the main and sub receivers. With the original synths, moving the VFO even a small amount causes both the main and sub synths to be updated. Since they use separate LC oscillators, the phase relationship will change. The two will remain phase-locked to the reference, but the absolute value of the phase between the two synths will be some value between 0 and 180 degrees. We'll add this to the FAQ. 73, Wayne N6KR On Mar 2, 2015, at 6:10 PM, Walter Underwood wrote: > Start with the FAQ here: http://www.elecraft.com/manual/KSYN3A%20FAQ-ver-C-2.pdf > > The original announcement on this list described it like this: > > The KSYN3A synthesizer module is a completely new design that improves on the original KSYN3 in several ways: > > ULTRA-LOW PHASE NOISE > The KSYN3A significantly improves the K3's already excellent RX and TX phase noise at close carrier spacings.

If you need quick access to the 600-meter range (~475 kHz), you can use any of several different ways to get to it: - the four per-band "quick memories" on 160 m - the 100 general-purpose memories - direct frequency entry - a programmable function switch As an example of the latter, you could create a K3 command macro using K3 Utility, such as: FA00000475000;MD3;PA0; This sets VFO A to 475 kHz, CW mode, with the preamp off. Of course you would also want to bring the signal in through RX ANT IN or XVTR IN, so the high-pass filter in the T/R switch is bypassed. Using XVTR IN requires setting CONFIG:KXV3 to TEST. We may provide a simpler way to do this in the future. 73, Wayne N6KR On Mar 2, 2015, at 6:28 PM, wrote: > Hi Wayne > > with the new board and software up dates is there a new band or do you > just keep tuning below > the BC band,,,, if we ever get 600 meters the K3 would be a great and > only rig to have > coverage > > Bob K3DJC > > > On Mon, 2 Mar 2015 18:21:50 -0800 Wayne Burdick > writes: >> Some users of the new synthesizer have also reported an improvement >> in the way diversity mode sounds.

As I said before, if the benefit is useful to you now, by all means buy the upgrade now. If it isn't, it simply becomes a race between inflation and potential increases in cost whether or not it makes any sense to do so. Everything else you said is simply a rationalization. 73, Dave AB7E On 3/2/2015 11:50 AM, Barry Baines wrote: > Dave: > > You raise an interesting question, and the answer depends upon the underlying premise that drives your decisions. > > If you presume that indeed you plan to sell the rig in a couple of years and that best way to sell a rig in the future is to have it "current" when you place it on the market, then presumably that means purchasing upgrades prior to placing it on the market. The question then becomes "buy the upgrade now or buy later?" The answer depends upon how you view the benefits of the upgrades: > > 1. Buy it now before potential prices increases later for those upgrades.

Recognize that the future value of the radio may be enhanced by adding the upgrade, but the "net value" of that rig will likely not increase as much as the cost of the upgrade. "Depreciation" coupled with the recognition that there is likely no warranty carry forward if the upgrade is installed by the prior seller means that the value to the buyer is less than what you paid for it. In other words, you'll get more for the rig, but the numbers may not offset the cost of the upgrade itself. > > 3. If you're going to install the upgrade at some point in the future anyway and you can afford to pay for it now, why not do the upgrade sooner rather than later? That way you'll also gain the benefit of the improvement for the remaining time that you own that rig, offsetting to some degree the "cost" of that upgrade through the enjoyment of those enhancements. This rationale is similar to your comment about making the purchase because you want the benefit of the upgrade. I'm adding to that sentiment by suggesting that if the purchase will definitely be made at some point, it is better to do so sooner rather than later so that you can benefit from it as well. > > 4. After using the enhancements it may be conceivable that the capabilities of the "new rig" may preclude the desire to sell it, thus avoiding the pain and suffering of placing it on the market in the first place and then going through the process of deciding what to get next. > > 5. Even if we decide not to do the upgrades and later sell the rig, the relative value of the "base case" is likely enhanced versus other products because the buyer has the option to add the enhancements. The rig is not locked into only those capabilities that existed at the time of production. > > The same approach should be considered in other major transactions. For example, if you know that you'l be selling your home in 3-5 years and recognize that some enhancements are needed to improve the marketability, why not do the upgrades sooner rather than just before placing the home on the market? That way you'll have the opportunity to enjoy the enhancements plus costs never go down, they always go up. Lock-in those costs earlier and not pay more later. Heck, you may decide after doing the enhancements to not sell after all, which is probably cheaper than going through the pain and suffering of selling one home, buying another, and then getting the new home setup the way you want it. > > Of course such decisions in amateur radio or other aspects of life are not always based on "logic" or economics. And each person has a different interpretation of cost vs. benefit, thus driving different decisions. I think we can all agree, however, that having Elecraft provide improvements to their products through both firmware and hardware updates is generally a good thing and that the marginal cost of these improvements has been less than purchasing a brand new comparable rig from Elecraft or someone else's product. > > > FWIW and Enjoy the Ride, > > Barry Baines, WD4ASW > Westborough, MA > > > > >> On Mar 2, 2015, at 1:16 PM, David Gilbert wrote: >> >> >> Please explain the advantage of spending all that money now instead of potentially spending it several years from now when you might ... might ... want to sell the rig.

That opened my eyes to something I'd read, but clearly not absorbed: i.e. when a modified BFO is saved, the K2 re-calculates the value of VCO needed to obtain the same AF tone as before. Although the audio moves moves when the BFO is adjusted, once the BFO is saved, the tone goes back to where it was (or within 20Hz anyway). One thing though. Unless it's just my KSB2 filter, you can still see WWV's 100Hz sub-carrier on DM780 when the filter skirts are set as you suggest. It's very low, but DM780 has a high dynamic range and the carrier is just visible.

If you need quick access to the 600-meter range (~475 kHz), you can use any of several different ways to get to it: - the four per-band "quick memories" on 160 m - the 100 general-purpose memories - direct frequency entry - a programmable function switch As an example of the latter, you could create a K3 command macro using K3 Utility, such as: FA00000475000;MD3;PA0; This sets VFO A to 475 kHz, CW mode, with the preamp off. Of course you would also want to bring the signal in through RX ANT IN or XVTR IN, so the high-pass filter in the T/R switch is bypassed. Using XVTR IN requires setting CONFIG:KXV3 to TEST. We may provide a simpler way to do this in the future. 73, Wayne N6KR 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From no3m at no3m.net Tue Mar 3 02:42:18 2015 From: no3m at no3m.net (Eric NO3M) Date: Tue, 03 Mar 2015 02:42:18 -0500 Subject: [Elecraft] Synthesizer Issue In-Reply-To: <201503030730.t237URbo022431@denali.acsalaska.net> References: <201503030730.t237URbo022431@denali.acsalaska.net> Message-ID: <54F565DA.40602@no3m.net> Press-Hold "MODE up" is to put the rig in TX TEST (ie. disable RF output), not the same as CONFIG:KXV3=TEST.

With the Old synths since the phase relationship between the 2 vfos would shift after TX the positioning of callers in the Image would alter after each transmit operation, with the new Synths this no longer happens. The already very good Diversity mode has gotten much better with this upgrade. I'd also suggest that folks who didn't take to diversity before might wish to give it a second try. For Diversity reception the RX antenna needs to be different than the TX antenna (E.g a vertical and a beam, or a doublet ) you don't need a dedicated RX antenna, it just needs to have different characteristics than the main antenna. Physical separation &/or polarity differences will also help. For me, the price of the upgrade was worth it for the Diversity improvements alone 73 Brendan EI6IZ On Mon, 2015-03-02 at 18:21 -0800, Wayne Burdick wrote: > Some users of the new synthesizer have also reported an improvement in the way diversity mode sounds.

It is made by Jackson Harbor Press and has some mods made by Clifton Labs. There is a lot of info on the Clifton Labs website about using this kit. It was really cheap in comparison to even a single Synthesizer board and there is no sensitivity roll off. I think I paid $14 and had to add a diecast box enclosure and a DC feedthru connector with two BNC jacks. NAA is very strong as are a myriad of navigation beacons and a few low band broadcast stations from Europe and Africa. The big problem is man made noise from all sorts of consumer products. I use my 160 M beverages to receive. You could also make up or buy an active antenna and maybe get more isolation from man made noise. It would have to be matched as the normal input is low impedance. I think the low freq converter is a great amount of fun to play with. $14 is about what you pay for a good hamburger these days!!

Personally, I like the tone bout 500 Hz. Don't forget that a square wave is made up of a sine wave + its odd harmonics. The higher the fundamental freq, the higher those first few, and most important, odd harmonics are. This can cause the waveform to lose its sharp edges and sound mushy when there is attenuation of those higher freqs due to hearing loss. Re musical ability, I played clarinet in jr high school and early high school, but gave it up because they required performing in marching band at the weekend football games - this interfered with contesting! I can play a little piano by ear, but never took lessons - one of my regrets...

I haven't found the Write commands to do that yet. Can you or any other really smart guys elaborate? For example, Let's say I'd like to create a toggle with a single macro. I would like it to do this without having an external application controlling things. So, internal to the K3, a macro would perform one or more functions, then before exiting, would rewrite itself to "unset" what was just done. Using the sample macro from Table 2 in the Programmers Reference for "AMP ON" and let's just assign it to say, Macro 1 In pseudo-code, I'd like it to run: MN019;MP001;MN255;PC065;DB65;DB77;DB80;DB32;DB79;DB78 and then, before the macro finishes, I would like it to rewrite itself to: MN019;MP000;MN255;PC100;DB65;DB77;DB80;DB32;DB79;DB70;DB70 Each time Macro 1 is executed, it toggles the Logic 1 output and alters the power output and displays "AMP ON" (or AMP OFF). One button thus becomes a toggle. Press a button, the external amp is enabled, and the drive is lowered for it. Press it again, and the amp is disabled and drive is raised back. Seems like all I need is a macro command that allows a new macro string to be written, especially to the one running at the time :) You could also have one macro change other macros in this way. In effect, you would only be limited by your imagination and what you can get stored in 120 character pieces. Hopefully we aren't limited in how many FLASH Write operations can be performed to the EEPROM. (1 million or more maybe? ) Since the K3 Utility obviously has the ability to write to the macro storage locations, would it be possible for macros to eat their own dog food too? If the macro language supports basic branching, I guess it could be done inline to the macro and not have to rewrite itself so... *Q2*: Is there a way to do IIF (or IF/ELSE) branching in a single macro? (strictly a wishlist item) In other words: IF (value) THEN (macro string) ELSE (another macro string) All this comes from my experience in making SCOM 7K controllers self modify it's macros to make wonderful things happen. Thanks! This is about to become very interesting... KD4Z - Warren (K3 / P3 Kits scheduled to arrive this Monday) On 3/3/2015 8:48 AM, Harry Yingst via Elecraft wrote: > 10 ?

For example, Let's say I'd like to create a toggle with a single macro. I would like it to do this without having an external application controlling things.? So, internal to the K3, a macro would perform one or more functions, then before exiting, would rewrite itself to "unset" what was just done. Using the sample macro from Table 2 in the Programmers Reference for "AMP ON" and let's just assign it to say, Macro 1 In pseudo-code, I'd like it to run: ? ? MN019;MP001;MN255;PC065;DB65;DB77;DB80;DB32;DB79;DB78 and then, before the macro finishes, I would like it to rewrite itself to: ? ? MN019;MP000;MN255;PC100;DB65;DB77;DB80;DB32;DB79;DB70;DB70 Each time Macro 1 is executed, it toggles the Logic 1 output and alters the power output and displays "AMP ON" (or AMP OFF).? ? One button thus becomes a toggle.? Press a button,? the external amp is enabled, and the drive is lowered for it.? Press it again, and the amp is disabled and drive is raised back. Seems like all I need is a macro command that allows a new macro string to be written, especially to the one running at the time :) You could also have one macro change other macros in this way.? ? In effect, you would only be limited by your imagination and what you can get stored in 120 character pieces.? Hopefully we aren't limited in how many FLASH Write operations can be performed to the EEPROM.? (1 million or more maybe? ) Since the K3 Utility obviously has the ability to write to the macro storage locations, would it be possible for macros to eat their own dog food too? If the macro language supports basic branching, I guess it could be done inline to the macro and not have to rewrite itself so... ? ? ? *Q2*: Is there a way to do IIF (or IF/ELSE) branching in a single macro?? (strictly a wishlist item) ? ? In other words:? IF (value) THEN (macro string) ELSE (another macro string) All this comes from my experience in making SCOM 7K controllers self modify it's macros to make wonderful things happen. Thanks!?

When you use rotatable macros you can use a single button to have it rotate through macros.

Hopefully they will help you understand how to create your own macros which can be used to rotate between a series of parameter changes via a single PF1 or PF2 key press. Have fun playing with them, without as many headaches that I had in learning how to get them to work. 73, Rich - K1HTV For those of you who want to play more with macros, here are four that I use to set up my K3 for USB, CW, DATA-A and RTTY. Parameters that are set up include mode, receiver bandwidth, audio input connector (Front Panel for microphone, rear Line-In jack for DATA-A modes), Mic Gain and Compression level for SSB, CW Speed, VFO lock for DATA-A modes like PSK31, JT65 and WSPR. You can add or change other parameters in the macros for the various modes as you see fit. Macros are created using the "K3 Utility" program on a computer connected to the K3 via one of its COM ports. 16 Macros can be save in the "K3 Utility" but only the first 8 macros can be uploaded to the K3. The macros can be tested using the "K3 Utlity" in real time. Once they have been uploaded to the eight K3 internal macro memory locations, they can be assigned to various keys. Each can be assigned to any of the M1-4 (Tap) keys, or M1-4 (Hold), or the PF1 or PF2 (Hold) keys. ***NOTE*** In the case below, 7 macros are created using the "K3 Utility" program. The first 4 macros (associated with 4 different modes) are loaded into MACRO memory positions 1,2,3 & 4 and programmed into the PF1 key. The last 3 macros (associated with setting 3 different power levels) are loaded into MACRO memory positions 5, 6 & 7. After they are loaded, when you HOLD the PF1 key the K3 will toggle between the USB, CW, DATA-A and RTTY modes. The 7 character mnemonic assigned to that mode wil flash briefly on the LCD screen. Wait for it to flash before HOLDing the PF1 button to toggle to the next mode. In a similar manner, when you HOLD the PF2 key, the power K3 level will switch to one of three different power settings.

The "#" below is the number of the macro memory location in which to store the particular macro in the K3. Since each macro command references a particular K3 memory to be used, do NOT change the K3 memories in which the macros are stored without making any necessary changes to the "MN110;SWTnn;" command. The sequence that holding the PF1 key will follow can be changed by changing the SWTnn command for each mode. In the example below, by holding the PF1 key, the switching sequence is USB, CW, DATA-A, RTTY, then back to USB. The two macro commands used to set up the next mode called is the MN110 (MACRO) followed by the SWTnn (keypad number 1-4) corresponding to the four modes programmed into those keys). Here is what is used for the sequence USB,CW,DATA-A,RTTY,USB : USB Macro #1 #1, MN110;SWT12 = Use Macro #2 (CW) next CW Macro #2, MN110;SWT13 = Use Macro #3 (DATA-A) next DATA-A Macro #3, MN110;SWT24 = Use Macro #4 (RTTY) next RTTY Macro #4, MN110;SWT11 = Use Macro #1 (USB) next Here is what is used for the sequence RTTY,DATA-A,CW,USB: USB Macro #1 #1, MN110;SWT24 = Use Macro #4 (RTTY) next RTTY Macro #4, MN110;SWT13 = Use Macro #3 (DATA-A) next DATA-A Macro #3, MN110;SWT11 = Use Macro #1 (CW) next CW Macro #2, MN110;SWT11 = Use Macro #1 (USB) next Here is what is used for the sequence CW,RTTY,DATA-A,USB: CW Macro #2, MN110;SWT24 = Use Macro #4 (RTTY) next RTTY Macro #4, MN110;SWT13 = Use Macro #3 (DATA-A) next DATA-A Macro #3, MN110;SWT11 = Use Macro #1 (USB) next USB Macro #1 #1, MN110;SWT12 = Use Macro #4 (RTTY) next = = = Once you have determined the mode sequence, here is the procedure used to program multiple macros into one of the PF1, PF2 or M1-8 keys: With the K3 powered on, open the K3 Utility. Click on the "Port" tab then click "Test Communications". If the test is successful, click OK and proceed. Click on the "Command Tester/K3 Macro" tab. Click on "Edit Macros" in the upper right corner. You can cut the "Macro Label" and the "Macro Commands" from above and paste them into the correct boxes for each macro number. The #[1-7] identifies which macro memory number in the K3 Utiliy to paste the info into. When all the data has been entered: Click on "Write Macros 1-8 to K3". Click "Save" then close or minimize the K3 Utility. Next, at the K3, to assign the four macros to the PF1 HOLD key: 1) Hold the MENU key. 2) Rotate the VFO-B dial so it reads to "MACRO" on the lower half of the LCD screen and the word "FUNCTION" above it. 3) Tap the first macro # to be entered (tap keypad #1). The LCD will read "Function MACRO #" 4) HOLD the PF1 key until "PF1 SET" appears. Next tap keypad #2, the hold PF1 again, then tap keypad #3 and hold PF1. Finally tap keypad #4 and hold PF1. All macros have now been programmed into PF1-HOLD key. 5) Tap the "Menu" key and MACRO will disappear from the LCD display. Follow the same steps to assign the three "Power Level" macros 5,6 & 7 to the PF2-HOLD key. Test the mode change with repeatedly HOLD (not TAP) the PF1 key. You should see a brief mnemonic on the LCD screen for each mode. Test power level with HOLD of the PF2 key. You should see a brief mnemonic on the LCD screen for each power level. 73, Rich - K1HTV ps There is another macro which can be placed in the 8th memory and assigned to the M4 (HOLD) key: Mem MacroLabel Macro Commands ------------------------------ #8 SCAN-M4 SWT15;SWT15;SWT15:SWT15;SWH41; Follow the same 5 steps above to assign the macro in K3 macro memory #8 to the M4 (HOLD) key. To do a scan, first set VFO-A to lowest frequency to be scanned. Next set VFO-B to the highest frequency to be scanned. Tap V>M then rotate VFO-A to channel 00. Tap V>M again to store the two freqs in Frequency Memory channel 00. To start the scan hold the M4 key. = = = = = = = = = Wayne, *Q1*: Did you just say that macros can be self-modifying! I haven't found the Write commands to do that yet. Can you or any other really smart guys elaborate? For example, Let's say I'd like to create a toggle with a single macro. I would like it to do this without having an external application controlling things. So, internal to the K3, a macro would perform one or more functions, then before exiting, would rewrite itself to "unset" what was just done. ............ All this comes from my experience in making SCOM 7K controllers self modify it's macros to make wonderful things happen. Thanks! This is about to become very interesting...

As I said before, if the benefit is useful to you now, by all means buy the upgrade now. If it isn't, it simply becomes a race between inflation and potential increases in cost whether or not it makes any sense to do so. Inflation and potential cost increases are indeed components of "time value of money" as well as what is the expected value of the radio in the future? I did not use that phrase, but the concept of "time value of money" includes expected inflation/cost increases as well as the projected "price" for an item. I also made the initial presumption that the "widget" would be purchased in any event in the next couple of years and installed in the radio; I wasn't suggesting that the decision to purchase in of itself is the proper one to make. Please keep in mind that "Time Value of Money" basically states that a dollar today is worth more than a dollar tomorrow. The longer the horizon, the less valuable "future money" is worth in today's environment; that is why future earnings are discounted when estimating the value of the same dollar amount after taking into account any potential future income stream from interest or other revenue generator using those same funds. In today's world where current interest rates are almost non-existent and there is the potential for future price increases, and assuming that the purchase decision has been definitely made ("I'm going to buy this either today or next year") the "time value of money" concept suggests that if you have the funds, buy it now rather than later because of the likelihood that your dollar will buy you less in the future than today. > Everything else you said is simply a rationalization. EXACTLY! Everyone implicitly or explicitly makes purchasing decisions based upon a variety of factors and considerations and we all attempt to organize ("rationalize") potentially disparate information in a way that makes sense to us. These may include: 1. Emotion. "I gotta have one of those!" or "The joy that I get from this is worth the price." 2. Utility. "The benefit in terms of how I use my radio will be enhanced by this widget by x%." 3. Cost/Benefit Analysis. "The cost of the widget is less than the perceived value of using this widget". 4. Future Value. "My equipment will be worth more to someone else if this widget is included." 5. Future Return. "When I sell my radio, the incremental revenue gained by including the widget will be greater than the cost of the widget" or "When I sell my radio, the incremental revenue by including the widget PLUS the value of the benefit of using the widget while I owned it is greater than the cost of the widget." 6. Liquidity. "Can I afford to buy it now given other purchasing needs that may have a higher priority?" 7. Alternative Choices. "I have only $xxx to spend on my amateur radio hobby. Is this the best way to use my dollars, or are there other products that will fill more important "needs" than this one?" This last consideration notes the need to prioritize purchasing decisions. One definition of economics is roughly "how allocation of scarce resources is done in a world of unlimited wants." Our pocketbooks are not deep enough to cover all "wants"; everyone has to prioritize which "wants" are met based upon their own criteria. Against these "rationalizations" is whether "future reality" meets our expectations. Since no one can predict the future, we all make financial estimations based upon past experience, observing current conditions, making assumptions about the future, and perhaps "hope." We're always taking "bets" that our ability to predict future outcomes will produce a better result than a different decision. So everyone will come to their own conclusions and there is no universal "right answer". My response below was simply meant to highlight one possible approach to the question you originally asked ("Please explain the advantage of spending all that money now instead of potentially spending it several years from now when you might ... might ... want to sell the rig"), taking into account both the "cost of money" as well as how we might view depreciation and relative value of a widget to the purchaser today and the future buyer in a couple of years. I also noted that selling a rig has its own considerations and that Elecraft's process of product improvement may well allow the current owner to benefit from those enhancements and not sell the rig in order to gain the latest benefits in a different product. In other words, generally speaking it is usually better to pay for incremental improvements in a rig that is already paid for than to sell it used (at a discount) and purchase a replacement (new at full retail price) unless the new technology is such a game changer that the current value of current products are wiped out. Clearly this new "widget" has generated lots of buzz. And those that believe the cost of the new widget is "worth it" will buy it now because they believe it will bring significant benefit. If one doesn't see the value of this widget relative to other purchasing choices, they will defer on it.

The question then becomes "buy the upgrade now or buy later?" The answer depends upon how you view the benefits of the upgrades: >> >> 1. Buy it now before potential prices increases later for those upgrades. There is no guarantee that today's prices will remain unchanged (labor, materials and other costs of production do change) so this is an assumption that the likelihood is that prices will go probably go up. >> >> 2. Recognize that the future value of the radio may be enhanced by adding the upgrade, but the "net value" of that rig will likely not increase as much as the cost of the upgrade. "Depreciation" coupled with the recognition that there is likely no warranty carry forward if the upgrade is installed by the prior seller means that the value to the buyer is less than what you paid for it. In other words, you'll get more for the rig, but the numbers may not offset the cost of the upgrade itself. >> >> 3. If you're going to install the upgrade at some point in the future anyway and you can afford to pay for it now, why not do the upgrade sooner rather than later? That way you'll also gain the benefit of the improvement for the remaining time that you own that rig, offsetting to some degree the "cost" of that upgrade through the enjoyment of those enhancements. This rationale is similar to your comment about making the purchase because you want the benefit of the upgrade. I'm adding to that sentiment by suggesting that if the purchase will definitely be made at some point, it is better to do so sooner rather than later so that you can benefit from it as well. >> >> 4. After using the enhancements it may be conceivable that the capabilities of the "new rig" may preclude the desire to sell it, thus avoiding the pain and suffering of placing it on the market in the first place and then going through the process of deciding what to get next. >> >> 5. Even if we decide not to do the upgrades and later sell the rig, the relative value of the "base case" is likely enhanced versus other products because the buyer has the option to add the enhancements. The rig is not locked into only those capabilities that existed at the time of production. >> >> The same approach should be considered in other major transactions. For example, if you know that you'l be selling your home in 3-5 years and recognize that some enhancements are needed to improve the marketability, why not do the upgrades sooner rather than just before placing the home on the market? That way you'll have the opportunity to enjoy the enhancements plus costs never go down, they always go up. Lock-in those costs earlier and not pay more later. Heck, you may decide after doing the enhancements to not sell after all, which is probably cheaper than going through the pain and suffering of selling one home, buying another, and then getting the new home setup the way you want it. >> >> Of course such decisions in amateur radio or other aspects of life are not always based on "logic" or economics. And each person has a different interpretation of cost vs. benefit, thus driving different decisions. I think we can all agree, however, that having Elecraft provide improvements to their products through both firmware and hardware updates is generally a good thing and that the marginal cost of these improvements has been less than purchasing a brand new comparable rig from Elecraft or someone else's product. >> >> >> FWIW and Enjoy the Ride, >> >> Barry Baines, WD4ASW >> Westborough, MA >> >> >> >> >>> On Mar 2, 2015, at 1:16 PM, David Gilbert wrote: >>> >>> >>> Please explain the advantage of spending all that money now instead of potentially spending it several years from now when you might ... might ... want to sell the rig.

Message-ID: <201503031717.t23HHRsR016341@ingra.acsalaska.net> Dave, I guess if you only want to receive that is a good choice. The new SYNTH enables both Tx and Rx at below 490-KHz (current synth will work down to 490). For those interested in operating on 472-478 MHz the K3+(new)SYNTH makes this possible (with the addition of an experimental license from the FCC). I will get the new synth when I have the funds (cost is x2 as I have the KRX3). Early on air reports look good for general use and extension to the new 630 meter band is a real plus! 73, Ed - KL7UW Re: TEST mode - I stand corrected by Eric (NO3M). I do use CONFIG: KVX3 = TEST for operating on 600m (bad memory). From: "Dave Olean" To: , "Elecraft Reflector" Subject: Re: [Elecraft] K3: Any SSB user comments regarding the new synth?

It is made by Jackson Harbor Press and has some mods made by Clifton Labs. There is a lot of info on the Clifton Labs website about using this kit. It was really cheap in comparison to even a single Synthesizer board and there is no sensitivity roll off. I think I paid $14 and had to add a diecast box enclosure and a DC feedthru connector with two BNC jacks. NAA is very strong as are a myriad of navigation beacons and a few low band broadcast stations from Europe and Africa. The big problem is man made noise from all sorts of consumer products. I use my 160 M beverages to receive. You could also make up or buy an active antenna and maybe get more isolation from man made noise. It would have to be matched as the normal input is low impedance. I think the low freq converter is a great amount of fun to play with. $14 is about what you pay for a good hamburger these days!!

But, I think you can save 5 macro locations by using the "*" tag in your memories. What I have done is program memory #60-64 with the 60 meter frequencies. Then you tag each one with the "*". This means each time you select any one of them as you move the tuning knob you will step through all 5 in a loop.

For example, Let's say I'd like to create a toggle with a single macro. I would like it to do this without having an external application controlling things.? So, internal to the K3, a macro would perform one or more functions, then before exiting, would rewrite itself to "unset" what was just done.

MN019;MP001;MN255;PC065;DB65;DB77;DB80;DB32;DB79;DB78 and then, before the macro finishes, I would like it to rewrite itself to: ? ? MN019;MP000;MN255;PC100;DB65;DB77;DB80;DB32;DB79;DB70;DB70 Each time Macro 1 is executed, it toggles the Logic 1 output and alters the power output and displays "AMP ON" (or AMP OFF).? ? One button thus becomes a toggle.? Press a button,? the external amp is enabled, and the drive is lowered for it.? Press it again, and the amp is disabled and drive is raised back.

In effect, you would only be limited by your imagination and what you can get stored in 120 character pieces.? Hopefully we aren't limited in how many FLASH Write operations can be performed to the EEPROM.?

I think it was not generally understood that the absolute value of the phase relationship of the receivers would change as the VFO was moved. The only person I know that is currently using his K3 for doing this is Ed KL7UW, so he may be interested in this. 73 David Anderson GM4JJJ > On 3 Mar 2015, at 02:21, Wayne Burdick wrote: > > Some users of the new synthesizer have also reported an improvement in the way diversity mode sounds.

The "magic" is that the I and Q channels are 90 degrees out of phase with each other. Each channel is what could be referred to as a normal audio signal. The 90 degree fixed relationship between the 2 signals no matter what the frequency or amplitude "does the deed" - each channel carries the same information, but the phase relationship 'does the magic'. With the 90 degrees out of phase information one can create (or decode) any form of modulation wanted - I did that "way back when" in my EE classes using pure math - it is a bunch of sines and cosines with a lot of other things thrown it. When you think of it that way, remember that the sine and cosine functions are 90 degrees apart. My studies were back in the pure analog days and the math was "a bear", but today with ADCs available, those signals can be digitized and the math manipulated by a computer before sending the result to a digital to analog converter (DAC). A full understanding may require in-depth study into modulation forms and techniques as well as skills in manipulating math equations involving sines and cosines. De-modulation is similar, but the opposite of modulation. Sometimes it is helpful to keep the pure math relationships in mind to fully understand what is going on. For a simplified view, a spectum display can be created by using Fast Fourier Transforms (FFT) and also by other techniques which will transform from the time domain to the frequency domain. That is what is being done to present the display on the PX3. In the time domain, you see a signal like you would observe on an oscilloscope - amplitude vs. time. In the frequency domain, you see the amplitude vs. frequency at any one instance of time. The 90 degree out of phase signals are necessary to convert from the time domain to the frequency domain (or vice-versa). If you want to dig into the math behind modulation techniques, then be my guest. The nice thing about DSP is that the math can be done "perfectly" within the range of the resolution of the ADC and DAC devices used. How good the DSP is depends on how faithfully it can represent the analog signal, and that depends on the number of bits of resolution that are needed for the task at hand. Hopefully this information is helpful. You are asking a complex question, and several others have given you guides to more detailed info. You can either accept my simplified answer, or dig into it deeper and come out with the full details. 73, Don W3FPR On 3/3/2015 4:59 PM, Rstafford12 wrote: > I am having trouble with I/Q modulation. > 1) Do the I and Q components have a frequency, or are they just amplitudes.

You have already been given links to tutorials on the subject, but here are some short answers to your questions to get you thinking. 1) The I and Q signals do have a "frequency", but it's called 'sample rate'. I and Q are constantly changing, but they are being sampled, or measured, at a regular rate which is the sample rate. By the time I and Q appear at the input of your soundcard they are considered 'baseband' or 'audio' and no longer have a carrier frequency associated with them because they've been demodulated. Think about this: does CW coming out of your speaker have a frequency? Well, not a carrier frequency, because it's been removed in the detector or demodulator, and besides we can't hear at the carrier freq, but the CW definitely has a 'words per minute' rate which your ear locks on to when it copies the CW. This is kinda like sample rate. You could call it 'data rate'. 2) I and Q are always 90 degrees out of phase. But their absolute phase is unknown. So once you see I and Q, if they aren't squared up you can rotate them artificially so that they line up on the X and Y axes that you see in all the math books. This is easily done with a phase shifter, which is just adding a delay to I and Q. If you take a picture of a football field, and your camera wasn't perfectly parallel to the chalk lines, your mind automatically 'adds phase' so that the lines are nice and square in your mind. That's kinda how it works in a demodulator. I hope I answered the question you had.

Don?t be worried if this takes a while to absorb. It is a shock to pretty much all EE students, right up there with Dr. Burrus?s lecture on negative frequency (with the omega belt buckle). I/Q is a natural fallout of the complex Fourier transform, but that does not make it intuitive. wunder Walter Underwood wunder at wunderwood.org http://observer.wunderwood.org/ (my blog) On Mar 3, 2015, at 4:18 PM, Al Lorona wrote: > Hi, Richard, > > These are very good questions.

After cleaning all the tin plated contacts within my K3 and installing 5.13 I still ran into errors in calibrating my PLL. Being a retired engineer I committed a sin by making an assumption.

The first step in producing IQ output is to spit the RF into two parallel mixers that use the same frequency LO, but one is shifted 90-degrees in phase. The LO is the same frequency as the RF so one gets audio as an output (same thing one does in an SSB demodulator). The two resulting audio outputs are 90-degree out of phase with each other. In the typical SDR the next step it convert to digital using a analog to digital converter (ADC)(hams are using their soundcard as a ADC). The resulting two digital signals are out of phase with each other and can be processed by a computer (called an DSP = digital signal processor). Due to the unique mathematical properties of the two digital signals one can recover CW/DSB/SSB/AM/FM/PSK modulation types (and I may have left out others). This is a very rudimentary (non-mathematical) description. The true beauty of using IQ is its versatility. No longer does the receiver have to have a product detector, discriminator, envelope detector, etc. The DSP does it all in digital form and re-converts the demodulated signal back to audio (or displays the signal on a screen). http://www.kl7uw.com/MAP65.htm the diagram may help understanding. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From mike.ab3ap at gmail.com Tue Mar 3 20:56:25 2015 From: mike.ab3ap at gmail.com (Mike Markowski) Date: Tue, 03 Mar 2015 20:56:25 -0500 Subject: [Elecraft] I/Q In-Reply-To: <201503040149.t241ni3t044775@ingra.acsalaska.net> References: <201503040149.t241ni3t044775@ingra.acsalaska.net> Message-ID: <54F66649.6090403@gmail.com> Me neither, but here's a page with both nice illustrations and description: http://whiteboard.ping.se/SDR/IQ 73, Mike ab3ap On 03/03/2015 08:49 PM, Edward R Cole wrote: > not going to repeat what everyone has already posted: > [...] > > 73, Ed - KL7UW > http://www.kl7uw.com > "Kits made by KL7UW" > Dubus Mag business: > dubususa at gmail.com From kevin.stover at mediacombb.net Tue Mar 3 21:04:03 2015 From: kevin.stover at mediacombb.net (Kevin Stover) Date: Tue, 03 Mar 2015 20:04:03 -0600 Subject: [Elecraft] [OT]Test Message-ID: <54F66813.4070008@mediacombb.net> Testing. -- R.

Dual polarity diversity reception for eme requires software to recover the polarity information. Two programs that I am aware of do this: SM5BSZ's Linrad (Leif Asbrink) and MAP65 (Joe Tayor). The software require two phase-locked receivers tuned to the same frequency to produce two IQ outputs which are in-phase with each other. Then the amplitude difference will produce polarity information which can be displayed and the software can digitally maximize SNR for best sensitivity (digitally aligns the output to the polarity of the signal). This does require both preamps, downconverters, receivers, and SDR's to have a constant phase relationship. Both sw have calibration routines to compensate the fixed phase difference in signal paths. Gains need to be balanced, as well. This is virtually impossible to achieve perfectly so the sw designers added a utiltity to test the difference and add digital compensation to remove this. My preamps are within less than a dB difference in gain and the downconverter uses an identical ckt as does the K3/KRX3. I use two LP-Pan for the SDR running on the 1st IF's of the K3/KRX3 with them using a common LO. Finding a test signal to perform the calibration is the hard part. Some eme signals are close to 45-degree polarity that is needed for this procedure. I will eventually upgrade my K3 with the new synth boards. 73, Ed - KL7UW Date: Tue, 3 Mar 2015 22:21:13 +0000 From: David Anderson To: Wayne Burdick Cc: elecraft Subject: Re: [Elecraft] Synthesizer Issue Message-ID: Content-Type: text/plain; charset=utf-8 Wayne, For folks that were using the two receivers for VHF EME polarity diversity reception over a wide bandwidth with MAP65 software, where they would have gain and phase matched preamps this must be an improvement for them. I think it was not generally understood that the absolute value of the phase relationship of the receivers would change as the VFO was moved. The only person I know that is currently using his K3 for doing this is Ed KL7UW, so he may be interested in this. 73 David Anderson GM4JJJ > On 3 Mar 2015, at 02:21, Wayne Burdick wrote: > > Some users of the new synthesizer have also reported an improvement in the way diversity mode sounds.

I just popped in the new SYN boards and have played around with my K3 for a few hours. I could almost cry because this was the one thing I was looking for that the K3 was slightly deficient in.good smooth CW above 36-38 WPM with RIT or SPLIT on. I am thrilled to hear how nice it now sends CW without being "jumpy". I'm not a real QRQ guy but when I'm in a contest down in the Caribbean I need to CQ at ~42 wpm and the K3 just wasn't able to handle it previously. It now sounds as smooth as butter. I've also never before been a QSK guy (even though my delay is usually set at only 12ms) but the huge improvement in QSK is an added benefit and may make a QSK guy out of me yet. I even tried QSK using SPLIT/SUB just now and it was perfect. If the RX dynamics are anywhere near the improvement I've seen so far I'll have hit the lottery. I only have a wire in the attic here at the house so I can't really test the benefits of the better RX specs until I get the boards installed on my contest K3s (out in the country with good antennas) but even if nothing else changes, I'm just thrilled with this new upgrade. I can't wait to give it a full trial during an upcoming contest. Wayne and Elecraft team, thank you VERY much for figuring out a way to "defy physics" (as you previously thought was going to be needed) on this K3 improvement.

Even crack operators have admitted during the past few days that they occasionally forget their split state, with embarrassing consequences. This is proof that the indications can and should be improved, if possible. See my previous posting. OK, I?ll tell you what often messes me up. One of the aggravating things about the K3 is that you cannot move freely between modes if split is engaged. You can change from CW to SSB or vice versa, but if you are in Data mode, or if you are trying to switch to Data mode, it won?t go until you turn off split. I generally tune in a station with VFO A, then hit A>B (twice) and move B to the correct DX receive frequency. If split is on, everything is good. If, for some reason, I had split on, but then turned it off so I could change modes, I sometimes forget to turn it back on. I hate this. I wish I could just select whatever mode in VFO A I want, regardless of split ? the firmware should prevent me from transmitting in unsupported configurations, of course, with an appropriate message in the VFO B display. If this could be fixed, it would help prevent me from making this mistake. (Yeah, I know, can I not see the bright yellow delta-F light? You?d think so?.)

I have a similar issue wherein my bank account was depleted by some $4000 the day after I placed an order for a new K3 and for six days never heard a peep from Elecraft. In my case, I goofed up and sent my question to 'sales' instead of 'sales3' and instantly got a helpful response from 'Mike', who has since kept me pretty much informed (of the parts issue) of the status of my order. For me, I understand the 'delay in shipment' of my new K3 (because of the huge order of synthesizers) and easily accept it, what ruffled my feathers was not hearing anything about a delay or even acceptance with my order.

A dummy load and a DMM are sufficient - just follow the instructions in the manual. The K1 and the K2 both include provisions for reading the internal frequencies as well as other built-in tools. Of course there are other tools that can be helpful - Spectrogram is useful for providing a visual display of the filters, especially on the K2. Take a look at the K2 Dial Calibration article on my website www.w3fpr.com. If you need Spectrogram, look for the links near the bottom of my home page. The filter display works best if you inject broadband noise from a noise generator such as the Elecraft N-Gen. If you do not have a dummy load, consider the Elecraft DL1. A signal generator that can provide a 50uV output is handy for setting the S-meter (like the Elecraft XG1, XG2 or XG3). An RF Probe can come in handy if you need to do troubleshooting. The parts for an RF Probe are included with the K2 kit (but not the K1). If you have the skills to operate it and interpret the display, an oscilloscope with a 10X probe is a handy instrument to make the tasks easier, but it is not required. 73, Don W3FPR On 3/4/2015 12:43 PM, Doug Hensley wrote: > What test equipment is needed to accurately perform the alignment > and proper tuning of a used K1 or K2 ? > > I'm not looking for minimum recommendations nor NIST-Traceable > recommendations; just what is needed to make sure they are up to > spec or up to speed for the guy who wants to enjoy what they are > capable of doing.

I know this out of the area of most interest on this list so bear with me: I forgot to say that using diversity reception with the K3 for eme, the receiver (VFO-A) is set to a single frequency and not moved. Typically on 2m-eme this is 144.125 MHz. The K3 is placed into diversity reception and Tx SPLIT is engaged so that VFO-B controls transmit frequency. Changing Tx frequency is done with VFO-B which does not affect the diversity Rx. This is used for digital eme modes so the K3 is run in DATA-A (USB) mode to interface with a computer soundcard. Special SDR sw (MAP65) is run on the computer which decodes received signals and generates the transmit digital signal. Receive tuning is done in the sw on the computer (VFO-A is not moved from 144.125). The sw displays up to 90-KHz of the band (like a panadaptor) and receive frequency is selected using the computer on the digital frequency span display. So the receiver VFO is not moved to tune within this sub-band and all frequencies preserve the same phase relationship in both receivers in the K3. Rx tuning is done in DSP and not in the K3. Note: that I do not use the internal DSP (2nd IF) of the K3, but tap off the 1st IF to two phase-locked LP-Pan to generate two IQ baseband audio streams which are converted to digital by a special four-port soundcard (M-Audio Delta-44). This is quite different on how most use diversity Rx (where one tunes VFO-A for different signals). 73, Ed - KL7UW PS: as far as I am aware, I have the only dual-pol adaptive eme Rx that utilizes the K3/KRX3 combo. Other stations use dual channel SDR's such as the HB9DRI IQ+ receiver. ----------------- Date: Tue, 3 Mar 2015 22:21:13 +0000 From: David Anderson To: Wayne Burdick Cc: elecraft Subject: Re: [Elecraft] Synthesizer Issue Message-ID: Content-Type: text/plain; charset=utf-8 Wayne, For folks that were using the two receivers for VHF EME polarity diversity reception over a wide bandwidth with MAP65 software, where they would have gain and phase matched preamps this must be an improvement for them. I think it was not generally understood that the absolute value of the phase relationship of the receivers would change as the VFO was moved. The only person I know that is currently using his K3 for doing this is Ed KL7UW, so he may be interested in this. 73 David Anderson GM4JJJ snipped-------- > With the original synths, moving the VFO even a small amount causes both the main and sub synths to be updated. Since they use separate LC oscillators, the phase relationship will change. The two will remain phase-locked to the reference, but the absolute value of the phase between the two synths will be some value between 0 and 180 degrees. > 73, > Wayne > N6KR 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From kf7gc at arrl.net Wed Mar 4 14:32:19 2015 From: kf7gc at arrl.net (Tomy) Date: Wed, 4 Mar 2015 19:32:19 +0000 (UTC) Subject: [Elecraft] K2 Speaker Message-ID: <1073759212.2779418.1425497539313.JavaMail.yahoo@mail.yahoo.com> When pulling out the head phones from the jack I do not have the K2 speaker working.?Just the head phones speakers.

No it is not hard to replace *if* you know which screws to remove to expose the jack. If you do not have good desoldering equipment, crush the plastic part of the jack with pliers or whatever tool works, then remove the leads one at a time. Clean up with solder wick and if the holes still have solder in them, heat the solder pads and push a wooden toothpick or a stainless steel needle through to clear the hole.

No it is not hard to replace *if* you know which screws to remove to expose the jack. If you do not have good desoldering equipment, crush the plastic part of the jack with pliers or whatever tool works, then remove the leads one at a time. Clean up with solder wick and if the holes still have solder in them, heat the solder pads and push a wooden toothpick or a stainless steel needle through to clear the hole.

He's going to re-test this after the unit is calibrated. We tested a few K3s with new synths in our lab, and all of them had sensitivity very close to the first K3 Rob tested. On the contrary, the new synth reduces noise considerably over the old (as much as 20 dB lower noise at a 2-kHz offset), which only benefit all measurements. 73, Wayne N6KR On Mar 4, 2015, at 8:56 PM, Dick via Elecraft wrote: > > Please advise if I am reading the new Sherwood receiver data correctly: > > 1) it shows a nice 6-8dB improvement in 3rd order dynamic range after > adding the new synthesizer? > > 2) it shows that the K3's sensitivity has been greatly reduced from the > original 0.33 & 0.19 to 0.8 & 0.5 after the addition of the new synthesizer? > If this is true, this would be bad news for weak signal 6 & 10-m. > reception. > > 73, > Dick- K9OM > ______________________________________________________________ > 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 n6kr at elecraft.com From stewart at g3ysx.org.uk Thu Mar 5 05:10:33 2015 From: stewart at g3ysx.org.uk (Stewart Bryant) Date: Thu, 05 Mar 2015 10:10:33 +0000 Subject: [Elecraft] K3 TX-INH Message-ID: <54F82B99.6000906@g3ysx.org.uk> Does the TX-INH state over-ride all other TX commands?

If you want to make sure the remote K3 does not stay in TX state when you loose the connection it depends on your solution. If you're using the Remoterig boxes they take care of it automatically. As soon as the connection between both controllers fails the remote RRC shuts down the remote K3 completely. Concerning TX-INH: Yes, you can do it that way.

OK that sounds good, but if it is already transmitting will TX-INH override any other TX commands (such as an active TX; command) and unconditionally take it back to RX? BTW I am surprised that there is not an addon that provides ToT and also command system on, two feature that are standard in all of the otherwise rather less capable transceivers. 73 Stewart/G3YSX > 73, Olli - DH8BQA > http://www.dh8bqa.de > > > Stewart Bryant hat am 5.

Tune it in to WWV, then tune the K2 into WWV until the tones match exactly ("zero beat"), then run the calibration procedures. That will get you close enough that the K2's DACs become the limiting factor. Spectrogram (free software on your PC that uses the sound card to display the audio coming out of your radio) can be helpful with the above if you don't have a musical ear, and I think it is pretty much essential for the filter calibration (you can use the default settings provided in the manual to get more or less in the ballpark, but they are far from ideal). If you have an external power meter, that can be useful for peaking the band pass filters. A DL2 dummy load with DMM would also work, or you could even use the internal power meter (but the resolution is somewhat limited) Don W3FPR has a web page that is a treasure trove of handy K2 information: http://www.w3fpr.com/ 73, Matt VK2RQ > On 5 Mar 2015, at 4:43 am, Doug Hensley wrote: > > > What test equipment is needed to accurately perform the alignment > and proper tuning of a used K1 or K2 ? > > I'm not looking for minimum recommendations nor NIST-Traceable > recommendations; just what is needed to make sure they are up to > spec or up to speed for the guy who wants to enjoy what they are > capable of doing.

To do as you want, you would have to use KEYOUT to start a timer whose output is with TX INH inactive and after some period of time would turn TX INH on and stay that way. 73, Don W3FPR On 3/5/2015 6:02 AM, Stewart Bryant wrote: > On 05/03/2015 10:28, droese at necg.de wrote: >> Hi Stewart, >> what's the reason behind?

The K3 excels for this task, as I can easily eliminate offending nearby signals and noise. That said, I really do wonder if I would get noticeable improvement from the new synth board? I asked previously, however didn't receive any really definitive answers. Hence, I ask again. What improvements will I notice? Such as less white noise? Improved filtering of nearby signals?

Although I am not a particularly frequent telephony operator, I have used the MFJ 434B with the K3 and it works just fine. Because I use my Heil headset with several different (in Field Days etc) I have had to confront the problem of different vendors using different microphone connectors - and even worse, the same connector with different pinouts....my solution was to wire the microphone plug to the Yaesu standard - with apologies for using the Y word on the Elecraft list :-) - , set the headers in the MFJ to the Yaesu standard (and also the appropriate header to apply the polarising voltage to the electret microphone insert), and then build individual Yaesu - Elecraft, Yaesu - Icom etc. adapters for rigs that don't use the Yaesu pinouts. I'm afraid I don't know where you can buy pre-made cables, but making up the adapters is straightforward if a bit fiddly. I don't know if that will help in your particular situation (I suspect perhaps not), but on the principle that any info might come in useful I thought I'd chip in. 73, Quin G3WRR? ________________________________ From: "pastormg2 at verizon.net" To: elecraft at mailman.qth.net Sent: Wednesday, 25 February 2015, 4:05 Subject: [Elecraft] MFJ 434B Connections Hi, this is Mark Griffin, KB3Z. Has anyone connected a MFJ 434B Voice Keyer to the K3? I assume that I would connect my Heil HM-12 microphone to the external microphone jack on the front of the unit. The man from MFJ said I would have to set up the jumpers in the unit for a Kenwood. But for some oddball reason they use a modular cable plug to connect the 434B to my K3. I realize I would have to use the MIC Connector on the back of my K3 and would have to make the necessary change with the K3 so it knows that I am using the MIC connector in the back. But where do I find one of these Modular cables to connect the 434B to the K3. Any help or advice would be very much appreciated.

I assembled K3 serial# 8887 (FW-5.14) so far succesful but have a problem with the SUB RX and diversity. I plugged the coax from the BNC AUX-RX into the KRX3 at assembly time. When I switch on the SUB RX it gets its antenna input from there, which I can verify by plugging out the antenna connected to BNC AUX-RX and do not hear anymore the signals received before. So the connection between the antenna connected to AUX-RX and the KRX3 is already established and working. ! When I now, while SUB is active, press and hold SUB, the diversity ! mode is established and the decimal point of VFO A starts blinking, ! I hear a relay switching noise out of the K3 and the signal received ! by the SUB-RX before went off. So it looks to me as if the KRX3 is disconnected from my receiving antenna by switching from SUB to SUB-diversity. What gets switched at this moment and why? Switching on diversity should only bind/link the SUB RX to VFO A (the same as pressing A->B after changing frequency) but phase coupled this time, or I am totally wrong? Switching between Config:KRX3 ATU and AUX makes on difference, and no relay clicking is audible. Can anyone with a newer K3 (and new syntesizers) tell me if he is oberserving the same behavior? I am not quite shure if I have overlooked something at assembly time or if this is a firmware bug. -- 73, Klaus, DF1TL From k2vco.vic at gmail.com Fri Mar 6 07:56:56 2015 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Fri, 06 Mar 2015 14:56:56 +0200 Subject: [Elecraft] Useful P3 feature Message-ID: <54F9A418.2040002@gmail.com> Here is something I would like to see on the P3. The P3 saves the REF LVL setting per band. But of course the noise level on a given band varies as conditions change, and I find myself often adjusting the REF LVL. The optimum setting is with the REF LVL just below the noise level. Setting it higher loses detail, and setting it lower fills the waterfall with noise. What I would like would be to adjust the REF LVL to optimum with respect to the noise level and then save this relationship. Then I would like to be able to push a function button to automatically adjust the REF LVL to re-establish the same relationship. This would make the readjustment, which I find myself making every few minutes sometimes, much quicker and easier. I don't want to save the REF LVL. I want to save its relationship to the noise level. -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ From vr2xmc at yahoo.com.hk Fri Mar 6 08:57:58 2015 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Fri, 6 Mar 2015 13:57:58 +0000 (UTC) Subject: [Elecraft] FS: Rigol DSA815-TG Tracking Generator Spectrum Analyzer Message-ID: <756030656.2773758.1425650278780.JavaMail.yahoo@mail.yahoo.com> Hello Elecrafters, About two years ago, I bought this Spectrum Analyzer with a view to doing some RF projects. ?Eventually, I did not have the time and have left this unit packed and unused.

It is not a 12 or 13.8V battery, but rather a low voltage source that has a switching circuit ( aka noise) that generates the higher voltages, These are designed to do as advertised and charge phones and tablets at relatively low current. If you want battery operation, an SLA or LIFE battery is your best choice. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-external-battery-Maxtron-VERY-NOISY-tp7599790p7599799.html Sent from the Elecraft mailing list archive at Nabble.com.

Take a look at the K1 specifications to be certain the frequency stability is sufficient for your needs. Yes, there is some drift as is common in any analog VFO (and the K1 uses an analog VFO). The frequency determining capacitors are either polystyrene or NP0 disc ceramics which have good (but not perfect) temperature stability. If the VFO inductor is carefully wound with the turns tight to the core and it is properly secured, the K1 VFO frequency stability will be better than specifications. I have dealt with 2 or 3 K1s with drift outside the spec limits, and they were 'cured' by properly winding the inductor and/or replacing the poly capacitors. Most of the K1s that I repair have frequency stability well within the specs. 73, Don W3FPR On 3/6/2015 4:25 PM, J wrote: > I was interested in building a K-1 4-band, but learned the 4-band boards are > unavailable.

Message-ID: <20150306234242.MLH4B.67809.root@cdptpa-web06> This mainly for Jay, W6CJ. Don answered your question about the availability of the K-1 4 band module. That is a shame as it really made the K-1 more versatile. I am really enjoying mine. You also asked about the stability of the K-1's VFO. I had not heard of any issues before buying mine and haven't had any problems. There is a small drift when first turned on, but stabilizes within a short time (minutes). If you had a signal within the bandpass, it will not drift outside the bandpass during warmup. After the rig has been on a few minutes you will not notice any drift. Of course this is only my experience.

My suggestion would be to remove the board feom the website entirely. However, its my second K1 and I intend to hang on to it. Now I just need to decide what to build to pick up a few more bands. Yeah, I know but I already built two K2s and a K3 so I'm aiming a little lower this time.

The KFL1-4 used 16 of them. Due to their wide capacity range, the same capacitors could be used in all 16 positions and provide successful tuning. Those capacitors have been discontinued by the manufacturer. The problem is that there are no substitutes that could be used for all 16 positions, and it would take a great deal of engineering effort to determine the suitable substitutes for each position on the 4 band board. In other words, would a 3 to 15pf trimmer be suitable in the C1 thru C4 locations and would a 12 to 30pF trimmer be suitable in the C5 thru C8 locations and so forth. Furthermore, if the 17 meter band were chosen instead of the 15 meter band, which low range trimmer capacitors would be used for each band. I am speaking of examples for the engineering effort that would be required to select the best capacitor for each position and each band choice. It is not a trivial exercise. I certainly would not want to do experiments to select the appropriate replacement trimmers necessary to resurrect the 4 band board, and I am certain the engineering staff does not have the time to do that work. The documentation would get more complicated as well - for example, "if you have chosen the 15 meter band, use the red trimmer capacitors at location Cx but if you have chosen 17 meters, use the yellow trimmers at those locations" Hopefully you get the point of the complexity created by those wide range trimmer being no longer available. The values I have proposed above are only numbers off the top of my head for examples, they have no value in the real world. 73, Don W3FPR On 3/6/2015 6:46 PM, Ross Primrose wrote: > Looking at the parts list, I can't imagine which part is no longer > available.... > > 73, Ross N4RP > > On 3/6/2015 4:37 PM, Phil Wheeler wrote: >> Confirm.

I assembled K3 serial# 8887 (FW-5.14) so far succesful but have a problem with the SUB RX and diversity. I plugged the coax from the BNC AUX-RX into the KRX3 at assembly time. When I switch on the SUB RX it gets its antenna input from there, which I can verify by plugging out the antenna connected to BNC AUX-RX and do not hear anymore the signals received before. So the connection between the antenna connected to AUX-RX and the KRX3 is already established and working. ! When I now, while SUB is active, press and hold SUB, the diversity ! mode is established and the decimal point of VFO A starts blinking, ! I hear a relay switching noise out of the K3 and the signal received ! by the SUB-RX before went off. So it looks to me as if the KRX3 is disconnected from my receiving antenna by switching from SUB to SUB-diversity. What gets switched at this moment and why? Switching on diversity should only bind/link the SUB RX to VFO A (the same as pressing A->B after changing frequency) but phase coupled this time, or I am totally wrong? Switching between Config:KRX3 ATU and AUX makes on difference, and no relay clicking is audible. Can anyone with a newer K3 (and new syntesizers) tell me if he is oberserving the same behavior? I am not quite shure if I have overlooked something at assembly time or if this is a firmware bug. -- 73, Klaus, DF1TL ______________________________________________________________ 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 hlyingst at yahoo.com From k6dgw at foothill.net Fri Mar 6 21:56:43 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 06 Mar 2015 18:56:43 -0800 Subject: [Elecraft] Useful P3 feature In-Reply-To: <54F9A418.2040002@gmail.com> References: <54F9A418.2040002@gmail.com> Message-ID: <54FA68EB.4050800@foothill.net> Yep, that would be cool, although I'm not sure it's doable. Would likely work if you were switching bands often, but if you don't come back to a band in a reasonable time, the "average" may be as invalid as REF LVL currently is. I generally take K9YC's advice if it pertains to audio, sometimes I'm a little slower on non-audio things. Jim runs P3 spectrum averaging as high as it will go. I never did ... fascination with the jumping spectrum display? I'm currently running at 12 for the spectrum and OFF for the WF and the WF is what I look at and I like the results. I find I don't have to adjust the REF LVL nearly as much. Having found out that 12 is safe for averaging, I may push it up. But, seriously, to my surprise, it really does tend to hold the REF LVL much more constant which is what I was looking for in the first place. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/6/2015 4:56 AM, Vic Rosenthal 4X6GP/K2VCO wrote: > I don't want to save the REF LVL.

It's completely understandable and correct that Elecraft would not want to spend the effort to re-engineer this board. However some of us on channel don't see the task as rocket science and in most cases would be glad to provide that expertise as a side effort just to make that equipment useful. If Elecraft had even something as simple as unpopulated boards to purchase for use as prototypes, it would make that task quite simple. Dr. William J.

The end result of these measurements is that you should disable the K3's AGC while listening to AM BC. It sounds so much better.

To emulate this stable capacitance with trimmers now available, you'd have to use a hand-selected C0G cap in parallel with a much smaller trimmer for each of the original 16 trimmers. This would be extremely tedious for builders. So, while it is possible, it is not practical.

Where are you measuring the 13.8V in your PSU - at the output terminals? The behavior you see is to be expected as the K3 has V/I metering points on both the main board and on the KPA3 amplifier. If there is 0.05 Ohms of total resistance (power lead, PowerPole connectors, connections to the PSU, etc.) between the PSU and metering points and your K3 draws 18A at 100W TX power, the voltage as measured in the KPA3 will drop 0.9V (I * R -> 18 * 0.05 = 0.9V) between RX and TX. Since the KPA3 contains a 15V zener for overvoltage protection, many prefer to adjust the PSU's no load voltage to 14.8V to accommodate the ~ 1V drop due to connection losses in transmit. This permits the KPA3 to operate at nominal voltage and improves transmit IMD somewhat. 73, ...

These are 1-40 pF with a very low temperature coefficient. Trimmers still available have TCs that are 2 to 4 times worse, and have a higher minimum C. These are fine for applications where small drifts in C with temperature don't significantly alter the passband of the filter (e.g., in the KFL1-2, K2, and K3). But the KFL1-4 requires very high-Q filters in order to remove mixing products from both the pre-mixer and transmit mixer stages. The low minimum-C is needed for the higher-band filters. We found that if we used trimmers with a worse TC on the KFL1-4, then power output would temporarily drop (in some cases by 50-70%) when the K1 was operated at an ambient temperature quite different from that at time of alignment. That would be unacceptable for a rig often used outdoors. 73, Wayne N6KR On Mar 7, 2015, at 8:06 AM, "Wes (N7WS)" wrote: > On 3/6/2015 9:33 PM, Don Wilhelm wrote: >> The part number for the bare KFL1-4 board is E100129 as listed in the KFL1-4 manual. > > Is there a commercial P/N specified for the capacitors? > ______________________________________________________________ > 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 n6kr at elecraft.com From w3fpr at embarqmail.com Sat Mar 7 11:37:36 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Sat, 07 Mar 2015 11:37:36 -0500 Subject: [Elecraft] K-1 4-band Availability/Status?

The manufacturer see orders shrinking and determines that it is not economical to continue the manufacturing line.

I believe the only filter that comes with the radio is a 2.7 KHz. If you operate CW, you'll want at least one for narrow cw, say maybe 400 or 500Hz. IF you're purely an SSB op, you might consider the 1.8KHz filter for crowded band conditions or contesting. Speaking of filters, you can't operate 6-meter FM without the FM filter. Other than that, you can't go wrong with a basic configuration and add-on later. That's exactly what I did. But I didn't have my unit long before I ordered the KXV3A, which is required for the panadapter, and also provides an auxiliary rx antenna input. 73 and Good luck! -Chris K1AY On Sat, Mar 7, 2015 at 11:42 AM, Richard Gillingham wrote: > I'm thinking about purchasing the K3-100 kit.

The stock SSB filter is fine for casual CW operation. If your computer doesn't have an RS-232 port, you'll need a KUSB USB-to-RS232 adapter so you can do firmware updates. Other than that, a bare-bones K3 is quite sufficient. Alan N1AL On 03/07/2015 08:42 AM, Richard Gillingham wrote: > I?m thinking about purchasing the K3-100 kit.

Not > too narrow (usually), and not too wide. There's a potential misunderstanding here. The plug-in filters are ROOFING filters, and are there to protect the IF from overload by VERY strong signals. The IF bandwidth is NOT dependent on those filters. Rather, the IF in a K3, like the KX3, is filtered by DSP. Those filters DO add to the selectivity of the K3 by virtue of a process called "cascading," whereby they make the K3's filter skirts fall off more sharply when the roofing filter is the same bandwidth or narrower than the DSP IF. So -- you DO probably need a CW roofing filter if you're a contester, or if you have a close-in neighbor who is active on the same bands when you are. For general operation, the IF is enough. 73, Jim K9YC From n4rp at n4rp.com Sat Mar 7 12:52:02 2015 From: n4rp at n4rp.com (Ross Primrose) Date: Sat, 07 Mar 2015 12:52:02 -0500 Subject: [Elecraft] Contemplating Purchase of K3 In-Reply-To: <54FB3587.5080304@subich.com> References: <54FB3587.5080304@subich.com> Message-ID: <54FB3AC2.5090608@n4rp.com> Or, get the 500Hz 8-pole from Inrad... 73, Ross N4RP On 3/7/2015 12:29 PM, Joe Subich, W4TV wrote: > If you operate any CW or RTTY you will want the 400 Hz filter.

However, if you have not yet done so, you should make a copy of your -particular- rig's settings. Elecraft recommends doing that the very first time you launch the utility. I presume you have already done that with your KX3. Don't forget that there a several new features that must be enabled via the rig's menu, and that you need to power cycle the rig after updates, to have the new firmware take effect. I'm a QRP guy, so I don't have any hints regarding using an external amp. :) I'm sure others will respond. 73 de Ray K2ULR KX3 #211 On Mar 7, 2015, at 12:24 PM, W4MIL via Elecraft wrote: > > I've not been active in some time with my KX-3.

If you DX or contest, that could make a difference. I have the 400 (8 pole) in both receivers, but I'm now wondering about changing to the 200 filters 5 pole or 250 8 pole (I'm adding the new synth, when the backorder is fulfilled). An edge is an edge but I suspect the 3 db is a rather bare edge. There is filter choice commentary on the Elecraft site, updated since I made my purchase. Consider that required reading. Can someone who has made the change comment? I can't do a comparison, all filters slots are filled, both receivers matched. If you want to use the K3 on local 6M repeaters, the 13 KHz filter should be added (good for AM too). Adding the KXV3a gives you other useful options (required for either preamp). If you operate digital (JT modes in particular), the TCXO option helps. The KDVR3 saves your voice if you contest or DX. If your computer does not have a serial port, the Elecraft cable (comes with, make your choice which flavor you want) is fine. Along that line, getting a multiport USB dongle is simpler in the long run (I have a 4 port, so one USB controls everything K line). If you want to operate on the experimental band, the KBPF3 is required. If you ever want to take the K3 someplace else (field day, portable, mobile in the RV) the tuner would be handy to have; else get the KAT500 (later? also in preparation for an amp; life is too short for QRP and you can always turn the power output down). Rick's rule of radio: Buy ALL the options you THINK you might EVER want at the original time of purchase because the budget will never be there to add on. However Elecraft is the one exception, mods and updates are generally simple. I'd strongly suggest looking though the options and consider how YOU operate, how you intend to grow and if they'd be useful now (buy) or later (budget). The answer to your question becomes self-evident. Since you can add more later if your mode of operation changes, you can adapt (building a budget to get you there). Caveat: If you're new to HF, contesting or DXing, having the receiver dialed in for the WORST operating conditions is your best advantage... close in strong signals are common in CW (your best DXing mode) and digital.

An > edge is an edge but I suspect the 3 db is a rather bare edge. I started with 400 Hz, then added 250 Hz. I've defined the 400 Hz filter as 450 Hz (so that it switches in at 450 Hz) and the 250 Hz filter as 350 Hz. Both are 8 pole filters. I find that I nearly always have the IF set to 200-250 Hz for CW, and 400 Hz for RTTY. In other words, I rarely use the 400 Hz filter. It should be noted that the 250 Hz filter actually measures closer to 325-350 Hz. Since they're the same price, I'd buy the 250 Hz filter if I was going to buy one at all. 73, Jim K9YC From dave at nk7z.net Sat Mar 7 13:52:06 2015 From: dave at nk7z.net (David Cole) Date: Sat, 07 Mar 2015 10:52:06 -0800 Subject: [Elecraft] K3, Replacement Synth question In-Reply-To: <54FB3B5C.1090304@gmail.com> References: <1425741024.15814.136.camel@nostromo.NK7Z> <54FB3B5C.1090304@gmail.com> Message-ID: <1425754326.15814.148.camel@nostromo.NK7Z> Hi, Thanks for the info!

If your KAT500 goes out and you have to send it back to the mother ship for repair, you'll still be able to use any antenna you want. You won't be forced into finding resonant antennas for the bands you want to operate. Also, it will be much easier to operate portable (I know, you have the KX3 :-) ) if you ever want to do so. And, the K3 is a great rig for operating portable if you want more juice than the KX3 offers. Just ask anyone who's been on the recent DXpeditions that used the K-Line.

In other words, I rarely use the 400 Hz filter. Whilst the 250 Hz filter works for strong signals on RTTY, the group delay increases rapidly as one approaches the knee of the response. That group delay has a significant impact on RTTY and causes a loss of several dB snr on weak signals that can hardly afford the added hit. The main purpose of the *roofing filter* is to protect the analog to digital converter from overload by multiple strong signals at the same time (and to prevent the hardware AGC from activating). The difference in selectivity between the 400 Hz (435 Hz @ -6dB) and 250 Hz (370 Hz @ -6dB) - see http://www.elecraft.com/K3/K3_filter_plots.htm is only some 30 Hz on each side of the passband. If a strong signal is close enough to be in that 30 Hz a slight tweak of the shift control will move him out. Even then, it is entirely likely that any signal close enough to cause problems in the 400 Hz filter will have phase noise, splatter and/or key clicks that fall inside the passband of *either* filter and can't be rejected in any case. If one is looking for the most efficient combination of IF filters, consider 400 Hz (or 500 Hz if RTTY is not a priority) with the 200 Hz (5 pole) as the 200 Hz filter is tighter than the 250 Hz filter to at least -50 dB on the skirts (and the 200 Hz filter is less expensive than the 250 Hz filter). 73, ...

There are many SB2xx amps, made modern with a full set of Harbach mods, still in use and likely to be around as long as we have ham bands. There are little circuits that can be put in tiny boxes, which you can find with Google, but the permanent answer is to bring it up to spec with the Harbach mods. 73 and good luck, Guy K2AV On Saturday, March 7, 2015, W4MIL via Elecraft wrote: > > I've not been active in some time with my KX-3.

Yes! A computer cord is not heavy enough, especially if you are converting to 120 from 240 configuration. Current will be DOUBLE. Just buy the cable from E-craft and be done with it. Why skimp on a $2K amp? Don't forget also, that the fuse configuration/block has to be changed.

I bought the 8-pole filters: 2.8-KHz and 400-Hz. The former because I run diversity on a KRX3 (which only has the 2.8-KHz). I figured the steeper filters would be valuable for resale (if that ever came to happen). I also bought the 13-KHz filter for FM (on VHF using transverters; also works on 10m & 6m). The 13-KHz is installed for AM. I have found in the very little CW operation on HF that I actually like tuning around with DSP bw = 500-Hz or wider. Once settled on a particular CW signal bw can be reduced to 400-Hz for quieter band reception. The only time I run CW at very narrow bw (typ. 100-Hz) is for CW-eme signals (very weak). I find those signals using a water-fall display (using either MAP65 display or Spectravue). Usually tune them with wider bw until exactly at the pitch I desire and then reduce DSP bw to enhance signal readability. Since you are a DXer, I suspect the 400-Hz 8-pole might give you a slight edge over the 500-Hz 5-pole in a crowded band (especially if you have close neighbor stations also vying for the DX). Then the new SYNTH ought to help a lot. My two cents observation from a non-expert. 73, Ed - KL7UW Date: Sat, 7 Mar 2015 18:10:59 +0000 From: Richard Gillingham To: "=?utf-8?Q?elecraft at mailman.qth.net?=" Subject: Re: [Elecraft] Contemplating Purchase of K3 Message-ID: Content-Type: text/plain; charset="utf-8" Many thanks for the recommendations.

Message-ID: Installed two KSYN3As today; worked V73NS on 10M/CW right after so I guess all is good. Installation fairly easy, though one suggestion for a revision to the instructions, noted below. More immediate question: What?s the best thing to do with the old boards? As I understand it: (a) KRX3 sub receivers are now shipping with the new synths. (b) It doesn?t work to have one old and one new. (c) Therefore anyone adding a KRX3 now has to buy an additional KSYN3A. And (d) - I think I saw this here a while ago - Elecraft (wisely) doesn?t want to deal with the old synths we-all remove. So, those of us who have upgraded don?t use the old ones but someone who wants to after-install a KRX3 might want one to avoid the additional $189. (That?s assuming a new KRX3 will work with an old KSYN3 - is that the case?) If I have all of that right, what?s the wise thing to do with old synths - some way to match up those who have them with those who want them? My suggestion about the instructions: The last step of the installation instructions is the Initial Checks. Calls for checking SYN1 and SYN2 on the VFO B Display. Fine; except SYN1 and SYN 2 don?t appear on Display unless Tech Mode is ?ON? in Config. Since it is recommended that Tech Md be normally off, I puzzled for a while about why Display wasn?t showing the SYNs - and then I read Fred Cady?s book, which toggled my memory about Tech Md. Maybe the instructions could add that, for those who - like me - don?t remember everything all the time. Also installed the P3 SVGA today. One anomaly there; will ask for help later if I can?t work it out.

They were used as the nulling capacitors in all the Elecraft integrated wattmeters, so for that application, the KAT2, KAT1, KXAT1, KAT100, and KPA100 have been impacted. The proper replacement for those wattmeter nulling capacitors is a 5-15pF trimmer E540012. Also impacted are the K2 trimmers used in the bandpass filters. The 5-15pF trimmers (E540012) work fine in the 10/12 meter bandpass filter, but do not have sufficient capacity for the 15/17 meter bandpass where a 7-25pF trimmer (Elecraft PN 540011) is the substitute. That fact requires a rewrite of the K2 manual stating that the red bodied trimmer capacitors are to be used at C32 and C34 while the white bodied trimmers are to be used at C44 and C46. That information will be good until the manufacturer decides to change the capacitor body color to something different (which is a constant exposure when trying to identify parts by the body colors). What I am saying is that the impact of the loss of these wide range temperature stable trimmers is not confined to the KFL1-4 board, but has a wide ranging impact not only for new Elecreaft kits, but for those wanting parts replacements. One must communicate the use to parts at elecraft.com (and sales) to obtain the correct replacement trimmer capacitor. The loss of that wide range trimmer capacitor is being felt in many areas of the K1, K2 and KX1 products. The impact is greater than just the loss of the KFL1-4 option. 73, Don W3FPR --------------------------------------------------------------- Herbert and all, There is no need for the KFL1 firmware to be open source, it is available from Elecraft as a spare part.

I have replaced a few of those blue bodied capacitors in the past, but the number has been very few considering the number of repairs I have done over the years. 73, Don W3FPR On 3/7/2015 5:49 PM, Humberto wrote: > Hi, > > I think this is quite a good idea !

You won't be forced into finding resonant antennas for the bands you want to operate.? Also, it will be much easier to operate portable (I know, you have the KX3 :-) ) if you ever want to do so.?

So, while it is possible, it is not practical. >>>> >>>> Wayne >>>> N6KR >>>> >>>> >>> >> ______________________________________________________________ >> Elecraft mailing list >> Home: http://mailman.qth.net/mailman/listinfo/elecraft >> Help: http://mailman.qth.net/mmfaq.htm >> Post: mailto:Elecraft at mailman.qth.net >> >> This list hosted by: http://www.qsl.net >> Please help support this email list: http://www.qsl.net/donate.html >> Message delivered to phystad at mac.com > From cyaffey at gmail.com Sat Mar 7 21:52:39 2015 From: cyaffey at gmail.com (Carl Yaffey) Date: Sat, 7 Mar 2015 21:52:39 -0500 Subject: [Elecraft] W1 SOLD Message-ID: Carl Yaffey K8NU Recording studio. cyaffeyNO_SPAM at gmail.com 614 268 6353, Columbus OH http://www.carl-yaffey.com http://www.grassahol.com From marrotte at verizon.net Sat Mar 7 21:59:33 2015 From: marrotte at verizon.net (Roger Marrotte) Date: Sat, 07 Mar 2015 21:59:33 -0500 Subject: [Elecraft] For Sale: Telepost LP-100 upgraded to an LP-100a Message-ID: <000001d0594b$e7e9e8b0$b7bdba10$@verizon.net> FOR SALE: A Telepost LP-100.

Maybe they need to get ready for more surprises. Sherwood's new numbers show a 6 dB lower noise floor without the preamp than the old synth and "sensitivity" numbers equivalent to the old synth with a 6 dB lower AGC threshold. That translates to a "hotter" *and* quieter receiver as well as a cleaner transmitter. The new K3 "no preamp" MDS is equivalent to that of the TS-590SG, Flex-5000, TenTec Orion, Yaesu FTdx5000 and Icom 7800 *with* their preamps (first step for the FTdx5000 and IC-7800). Very impressive. 73, ... Joe, W4TV On 2015-03-07 10:28 PM, Bill Frantz wrote: > Speaking at Radiofest today, Eric said they had been surprised by the > demand for the new synths.

I have just serviced a K2 where the previous owner had had soldering problems (untinned toroids, solder bridges, ...) as well as settings which were far off. I find it useful then to start by reading out the settings to figure out what the starting point is, as well as backing up all the values when the calibration has been completed. The AB3AP software is in the form of Java programs. My web browsers don't allow them to be run, but simply downloading the code and running them from the command line works fine.

Redoing my basement, adding insulation and sheet rock.....once that's done, I too must clean up the "wireless stuff" hanging out behind the K3, P3, two HP 23" displays, and Dell Optiplex 330 on the bench. While cleaning the wireless stuff up, I'm planning to follow some of the advice blogged by K9YC: replace zip cord with twisted pair (CAT5 type) for cabling (such as the winkeyer between the Dell and the K3) various items together, grounding the shielded of all boxes on the table to just ONE GND spot (which is also connected to GREEN safety). I'm also going to audit where the noise sources in the house are and add where needed CMC (chokes) to cut the noise level into the radio bench. For example, I have noted that the original contractor (19 year house) added one smoke alarm near the kitchen and one at each end of the basement. The cable for the later two runs just eight feet above my bench and the total length of that cable back to the breaker box is about 60 feet! That's likely a good antenna. I also need to audit all circuits (including door bell) running from the eight breakers in the main box and another 6 in the basement satellite box. Lots of potential antennas there for RFI pickup! Right now, my P3 shows a noise level on 30 meters of about 3 dB above reference. I also see several steady traces on the waterfall display below, finding that the source of that one at 10.122 is my LINKSYS router attached to my Dell with cable. So you see, the RFI cleanup is probably going to take longer than the basement redo project! 73, Phil, W0XI in Kansas. > > [(Fred Jenen...)

Interesting to watch to differences in the "fullness" of the band over a 50 kHZ range over time: The two antennas (tri-band beam and rotating dipole) sure show their different directivity when oriented the same direction.

I did that yesterday with my XG3 and it was pretty slick. No obvious change from the factory settings (my K3 is relatively new, about a year old), but I'm glad I did it. Motivation was that at some point yesterday 20 seemed to have died, and I wanted to check out the K3's RX. I did it only on 20 meters: Is there any reason to do it on more than one band?

In fact, it works so well that I have turned QRQ mode OFF. I can hear a slight change in 'weight' between QRQ engaged or disengaged (the state of which still changes as a function of engaging RIT, IT, SPLIT ...), but with the new Synth board, I actually prefer the timing w/ QRQ off. With QRQ disengaged, maximum sending speed is 50 WPM, whereas w/ QRQ engaged, the maximum speed is 100 WPM. I only use paddles, and I have no ambition (or capability) to send with paddles beyond 50 WPM, so for me, QRQ-OFF mode is PERFECT. Any and all other KSNY3A improvements/enhancements are just icing on the (K3) cake. 73, Dale WA8SRA > Barry - > > It will be interesting to hear from someone who has done that... but I put > two new synth boards in the K3 of W9FAM, and he is THRILLED at being able > to run QRQ without having to be in the QRQ mode, thus being able to use > RIT, without degradation of the CW his K3 is putting out. > > For him that is important every moment he is on the air...

Any help would be appreciated. Here are the symptoms: The spike appears at 11.8 KHz above the VFO A frequency, and stays at that distance as VFO A is tuned - that is, it moves as VFO A moves. It appears on 10, 15, 20, and 40 meters (haven?t tried others). The apparent amplitude is over S9. But there is no signal there - tuning across the spike?s frequency with the SubRX produces nothing audible in the K3. The spike disappears when SVGA EN is set to OFF. The spook appears although there is no SVGA monitor connected, and no computer connected to anything, so it?s not from some other box. Seems to be residing in the P3. Did not occur before the SVGA option was installed. Firmware in both the K3 and the P3 and its SVGA are current as of yesterday - but the anomaly appeared both before and after the updates, and before and after the synths were changed. Any ideas or suggestions? Thanks!

I don't really know what it takes to make the programs more useful. All I know is that everything that has to do with Java has gotten more and more difficult to use, especially for Windows users. I am running Windows 7 here myself. Therefore, after quite some struggle with browsers and security, it was a relief to find out that I could run the K2 Settings Retrieval Software from the command line in Windows by just typing in javaws params.jnlp after having downloaded params.jnlp to my harddisk. I realize that the security issues are caused by calls to your website. If a 100% local program could do the same, then perhaps that would make it simpler, but I am just a user, not a developer of these things, so I don't really know what it takes. ----- Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog: http://la3za.blogspot.com, LA3ZA Unofficial Guide to K2 modifications: http://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-Settings-Retrieval-Software-tp7599921p7599958.html Sent from the Elecraft mailing list archive at Nabble.com.

Here in Arizona we don't change our clocks, but just about everyone else does--Hawaii Doesn't, and there are a couple more pockets that don't change. Not that I particularly mind DST, except for the confusion it causes, but I never really understood how the claimed benefits were really backed up by fact. To me, the energy savings argument never made sense because, for one thing, it seemed like a lot of folks would run their air conditioning longer!!! Anyway, here's a link to the article: http://www.washingtonpost.com/opinions/five-myths-about-daylight-saving-time/2015/03/06/970092d4-c2c1-11e4-9271-610273846239_story.html?wpisrc=nl_headlines&wpmm=1 The article addresses various "myths" about why we have DST--it helps the farmers, it is healthier, it saves energy, business likes it, etc. None of these seem to stand up to scrutiny. In fact, there apparently is significant cost, in both dollars and extensive confusion, that counter the advantages--if they even exist! Apparently, even the cows get confused by DST! Hi. Right here in Arizona I marvel at how many people really struggle with the fact that, during DST, we are on the same time as California! Anyway, you may chose to believe what's written in the article, or not. It is an interesting discussion!

Objective measurements by ARRL Labs and by Rob Sherwood show that these radios are NOT "fine" transceivers. Most of them don't HEAR as well as a K3 (there are a few exceptions), and all of them are DIRTIER than a K3, many of them a LOT dirtier. Caps added for emphasis. Even the new Flex 6300 and 6700, which ARRL just reviewed and praised for its low phase noise and "excellent" keying are MUCH dirtier on CW than a K3. 73, Jim K9YC From w3fpr at embarqmail.com Sun Mar 8 19:54:03 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Sun, 08 Mar 2015 19:54:03 -0400 Subject: [Elecraft] PX3 Future Upgrades?

E3?FB was operating in split mode and was transmitting in REV RTTY and receiving in Normal RTTY. While I was operating in FSK D in split mode, the only way I found to toggle between Normal and Reverse was by depressing and holding the Mode switch as I went from Receive to Transmit. I was unable to go from Normal to REV by setting the A and B vfo?s when switching from Rx to TX. Is there a way to set the REV/Normal to follow the particular vfo in use at the time.

I still don't see why I would use/want it. I find (for me) what works great is to move the A/B cursor on the PX3 to the signal I want and tap the knob to go there. It seems to me with fixed mode I am still going to have to deal with display edges when I scan to/past the edge (unless there is an automatic new window). I guess I can see that moving the A cursor over the spectrum, being able to hear what you see and not having the display have to keep up with changes ("bounce"), might be more what my friend would have liked during the contest this weekend as we were also doing a radio demo for the cub scouts.

Likely Fixed-Tune will come first because a field-test of the code was out to a limited number of PX3 users several weeks ago.

The VFO A and B cursors are always there in Fixed-Tune mode [B may be off-scale right or left but there's an arrow to tell you which way it is]. They're where your VFO's are tuned, you don't have to do anything to "go there," you're there. Marker A and B are independent of this, you can turn them on or off, and if on and you put Marker A on a signal and tap the knob, you'll QSY there. > It seems to me with fixed mode I am still going to have to deal with > display edges when I scan to/past the edge (unless there is an automatic > new window). Yes, there is a new window, you don't have to do anything except keep tuning. On the P3 [and I'll bet the PX3 too when it is released], you have a choice of two behaviors: If you tune off the end of the display, you can set it to either give you the next full span, or the next half-span [i.e. tuning down past the edge, you see the lower half of the span you were on on the right and the upper half of the span you're tuning into on the left]. I use the full span shift. I set my span and centering so if I tune far enough down or up, the edge of the display will be the band limit. YMMV > I guess I can see that moving the A cursor over the spectrum, being able > to hear what you see and not having the display have to keep up with > changes ("bounce"), might be more what my friend would have liked during > the contest this weekend as we were also doing a radio demo for the cub > scouts. That's the second advantage of Fixed-Tune, the averaging in the spectrum plot remains constant until tuning past the end of the span. In tracking mode, the averaging must restart whenever you tune ... 1 Hz or more. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From frantz at pwpconsult.com Sun Mar 8 23:32:54 2015 From: frantz at pwpconsult.com (Bill Frantz) Date: Sun, 8 Mar 2015 20:32:54 -0700 Subject: [Elecraft] PX3 Future Upgrades? In-Reply-To: <54FCFE84.9090009@gmail.com> Message-ID: The big advantage, at least on the P3, is that when you move the tuning knob, you don't lose your signal averaging and waterfall history. Keeping the waterfall makes it a lot easier to tune to an infrequent signal, like the DX running a pileup. I haven't tried a keyboard on the P3 since it doesn't support hubs and all my spare keyboards are Apple keyboards with built in hubs. 73 Bill AE6JV On 3/8/15 at 6:59 PM, sm.shearer.01 at gmail.com (steve) wrote: >OK, thank you.

I would recommend using this software to record the settings right after an alignment, then remove the cable. If the BFO settings are to be re-installed, know that the 4 MHz Reference Oscillator may have drifted since the last alignment. If it is set correctly again, then the same BFO frequencies can be entered. Note that the BFO frequencies should be regarded as +/- 0.02 kHz because of the BFO DAC resolution. If you need information for accurately setting the 4 MHz Reference (C22), look at my website www.w3fpr.com article on K2 Dial Calibration. 73, Don W3FPR On 3/9/2015 9:24 AM, Sverre Holm (LA3ZA) wrote: > Hi Don > > Yes, you are right.

THAT'S why Fixed Tune Mode is so critical. Averaging is what allows us to pick weak signals out of the noise. Tuning, even very slightly, resets the averaging, making it FAR less useful. 73, Jim K9YC From jim at audiosystemsgroup.com Mon Mar 9 12:23:39 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 09 Mar 2015 09:23:39 -0700 Subject: [Elecraft] TS-990 In-Reply-To: <54FD17EE.40609@triconet.org> References: <9E1748497DCDA342A28EFCAB1C82CE58015B77A8@SVNT6-4.inepar.com.br> <51AE04A6.9030002@w2blc.net> <1370363759.95598.YahooMailNeo@web181005.mail.ne1.yahoo.com> <51AE1EC6.5090700@w2blc.net> <1370366602.85539.YahooMailNeo@web181002.mail.ne1.yahoo.com> <1370372919.83064.YahooMailNeo@web120304.mail.ne1.yahoo.com> <003901ce620b$5b0af490$1120ddb0$@net> <1370452578.89122.YahooMailRC@web181604.mail.ne1.yahoo.com><1370456288.38951.YahooMailNeo@web160201.mail.bf1.yahoo.com> <54FCDFB1.6050509@audiosystemsgroup.com> <54FD17EE.40609@triconet.org> Message-ID: <54FDC90B.5010607@audiosystemsgroup.com> On Sun,3/8/2015 8:47 PM, Wes (N7WS) wrote: > Has anyone other than me ever noted that Rob Sherwood doesn't own a > K3?

Does she OPERATE HF? Does she know what HF operators need? Does she design stuff with Pin One Problems? Does she know what a Pin One Problem is? Do YOU? What kind of operating do YOU do? I don't give a rat's ass about "new technologies" and the latest fads. I am both an engineer and an OPERATOR. I choose a radio that gives me the performance and the functions I need, and at a price I can afford. The K3s are my current choice. It is NOT a religious decision. Before that it was FT1000MPs, before that TS850s, before that a K2. Based on what I see of the performance and features of the current crop of SDRs, none are even close to offering what the K3 does. Someday that will change, and when it does, I may buy one -- if I'm not in hospice by then. I drive a big Toyota SUV because I need to haul stuff. I convinced my wife to buy a Prius because she doesn't. I have a modest music listening system, but a monster library of music on LP, CD, and DVD. As last count, >3,000 LPs, >4,000 CDs, and about 150 DVDs. I worked in pro audio, and for most of my professional life, people asked me about whatever the latest and greatest was. My advice, then and now, is to save their money and buy music by Prez, Billie, Pops, and Desmond. It is NOT about technologies. = = = = = = = And Michelle responded: K3s are great. Any solution in ham radio that makes the operator happy, and therefore leads to them being more efficient and achieving higher scores, is the optimum solution, for that ham, for that application. There is an assmption here of an objective ideal in terms of operating in contests. I don't think this assumption should go unquestioned. What works for one set of operators is not guaranteed to work for another. I use SDRs for (non-human-involved) cognitive radio research, and in experiments with new modulation schemes, for which they are absolutely necessary. I have a Flex, USRPs, boxes of HPSDRs, a BladeRF, a HackRF, and about a half dozen other custom boards and implementations in FPGA. I don't even consider legacy radios, outside of where I must have a simple cheap solution to radio sensor data back home (such as RFID). I'm an SDR zealot. I prefer the K3 for contesting due to a delightful user interface, portability, and durability. All of these radios under discussion are so far above what I would consider to be the performance cutoff for contesting, one should choose based on the remaining "highest nail" - the UI, or whatever else the situation demands. The Flex is an undisputed lab queen and is objectively "the best" in terms of stats. But we took K3s to the Cook Islands and Raro. If I go on another DXpedition, it probably won't be with a Flex. Not that I'm generally choosing - I'm a junior member of the DXpedition teams that invite me. I contest for fun, but I've put in enough hours with the local club to know that I'm not rig-limited. I know for a fact that I'd have to contest a lot more for the rigs I use to start limiting my scores, instead of my skill level limiting my scores. The Flex doesn't make me any better of an operator than the K3 or the 756Pro2. They all can have the killer app of panoramic display, which I depend upon. They are all easy enough to switch bands on. Above that, I'd need to put in so much more seat time in order for the Flex to start making a difference, and I just don't have that much time to devote to contesting. I have raced cars. If the objective measurements of transceiver performance can be likened to horsepower, then you obviously need a car with enough horsepower to compete. But if you pick a car based solely on this one axis, then you may end up backing a Corvette that fails to negotiate the twisty road, while the half-your-horsepower Porsche eats your lunch. Conversely, the Porshe will lose in the straightaway to the Corvette. Suspension, gearing, steering, track type, race format - etc. are are equivalent in importance to horsepower. So, If you want to talk about what the best contesting rig is, then I think you have to consider radios in a more multidimensional manner than by just comparing the equivalent of horsepower. Of which, Flex clearly seems to win. -Michelle W5NYV From elecraft at mailman.qth.net Mon Mar 9 12:24:22 2015 From: elecraft at mailman.qth.net (Don Putnick via Elecraft) Date: Mon, 9 Mar 2015 16:24:22 +0000 (UTC) Subject: [Elecraft] [K3] My K3 needs pimping Message-ID: <180264429.1627826.1425918262851.JavaMail.yahoo@mail.yahoo.com> Okay, folks.

I have read good reviews on eHam so I am wondering if there is a special trick to getting the Chameleon to perform as advertised. Anyone have experience with these antennas? So ..Not sure where to go from here. I am looking for advice on the current solutions I have or recommendations on something I have not tried yet. My main concern with portable use is weight. My main concern with home use is low visibility and also needing an antenna that works "well" close to the ground since I'm in a ground floor condo. I have debated playing around with wire (thin) loops since I have access to an SGC 230 and 237 tuner. I would love to know what has worked for others. Thanks for the help.

I decided to move to a different frequency, and had just pushed the buttons to start entering the new frequency, with a very strong/loud signal popped up right where I was listening. My hand shot to the AF gain knob, which I discovered was locked out. So I was stuck with way too much audio until I managed changed to a new frequency, at which point the AF control was re-enabled. Is there a reason why the AF control is locked out during keypad entry of a frequency? 73, Bob, WB4SON From sm.shearer.01 at gmail.com Mon Mar 9 13:59:25 2015 From: sm.shearer.01 at gmail.com (steve) Date: Mon, 09 Mar 2015 13:59:25 -0400 Subject: [Elecraft] Software suggestions for KX3 In-Reply-To: References: Message-ID: <54FDDF7D.8040805@gmail.com> The two I would recommend are fldigi and DXlab {both free}...

I have been a relicensed HAM since 2006 and am by no means a big or even medium gun. No towers, just wires and a vertical. I do not contest a lot but am an active DX'er. Last night, I was trying to get E30FB into my log for #299. In today's current state of DX'peditions, DQRM appeared, very persistantly I might add, on the DX transmit frequency (20M, CW). The DQRM was not exactly zero beat but real, real close. By using the 100hz filter setting (I have the 250Hz filter in both receivers) and shifting just ever so slightly I was able to hear them come back to my call and I was able to successfully make the contact. This is over a S5 DQRM almost exactly zero beat!! I honestly wonder if I could have done that with a different radio.

Of which, Flex > clearly seems to win. That claim hides a major blind spot. Sherwood's test numbers show that the K3 with the new synthesizer is every bit equivalent to the Flex-6000 series when one considers noise floor (MDS) (weak signal performance) and realizes that the Flex can not handle multiple very strong signals without serious blocking and compromised dynamic range due to A/D limiting. With the new synthesizer the K3 has a better MDS without a preamp than the Flex with its preamp enabled. The measured difference without a preamp on either unit is 18 dB! Even with a 20 dB preamp for the Flex (which reduces the strong signal handling capability by 20 dB and could be fatal with multiple strong signals), the Flex still has a 4 dB higher MDS (less sensitive receiver) that the updated K3 with its 10 dB preamp. So long as direct conversion SDRs have A/D limiting issues that occur at real world signal levels (e.g. on 160 meters within a few miles of 50 KW AM broadcast stations, on 40 meters in Europe with multiple strong broadcast signals in the band, etc.) the Flex SDRs simply can not be said to "win" any comparison of "horsepower" (and their user interface sucks!). 73, ...

In-Reply-To: References: Message-ID: <54FDE519.9070505@comcast.net> Mark, You are faced with what is becoming common. I assume you are running your KX3 barefoot. That makes your antenna installation critical. The problem with most simple antennas are they require a very good ground to really be effective. If you have been using the Buddy Pole as a vertical and many other variants, you are trying to use a 1/4 wave antenna with out a ground which is a must for this configuration. The Alexloop works well on 20-10 meters, but is very narrow band. As you already own one and if you are running QRP, use it. Just tune it around where you want to operate. You don't mention whether you have an attic in your town house and have access to it. If you do, a fan dipole in the attic works FB. The problem will be to run you feed line down. You have a few choices. One choice is to find the waste stack vent and feed your transmission line beside the pipe. There is usually enough room for this, but you can only run RG-8X for smaller, typically. The other choice is to run your transmission line like the cable guys do it, drill a hole in the wall in the attic and drop it down to where you want it to come in and drill another hole and bring it in. Portable antenna are interesting. You could use an end fed affair. The one I like is distributed by the Hawaiian Emergency Radio Club, or some name like that. They sell them as multiband antennas, but they work best with correct wire lengths for the band you want to operate. Changing to another wire in a 1 minute affair including recovering the nut that you drop on the ground. It is basically a 9:1 unum with a 1/2 wave wire attached. A couple of #22 gauge wires and the unum shouldn't exceed about a pound. All of these suggestion will work, But they will not perform as well a good beam or antennas in the clear. However, my suggestion for the portable antenna does do a credible job; I have one. 73, Barry K3NDM On 3/9/2015 12:48 PM, Mark Tellez wrote: > Hello all, > > > > I am a relatively new KX3 user.

It does work with the KX3. Just set it up for K3 operation. However, If you want to do it to the max, download a copy of Win4K3, $50, and buy a USB sound card that runs 24 bit sampling at 96KHz or better sample rate. They run anywhere from $75 to $150. That will give you spectrum display, radio control, CW/RTTY/PSK31 controls and macros, and an interface to HRD. The Spotting software in HRD will connect to the DX clusters and put your radio on frequency by just clicking. You will need to download a copy of com0com for port replication, but that is free. 73, Barry K3NDM On 3/9/2015 12:56 PM, Mark Tellez wrote: > Hello all, > > I posted a question on here a few weeks ago about software for controlling > and enhancing the KX3 experience.

I always thought that was to be used for a weak signal. The E3 was loud enough that I didn't think to engage it. I'll remember that in the future, though. The more I think about it, APF would be a useful tool for something like this. I'll have to create a Macro so I can switch between APF or Dual PB.

They are all great radio's in their own right and have their own distinct advantages and disadvantages. Anyone who would like to see all 3 in the shack are welcome to drop me a line (in bay area of course). So far I wouldn't be caught dead without my K3 in a contest and my KX3 with KXPA100 as needed is an awesome go-to travel solution of admirable performance in a pelican case. The flex does have a decent performing receiver but is still in its early stages of development feature wise and they are not cranking out updates with the same frequency that Elecraft does and their support eco system in in an equal fetal stage. But the platform does show some great potential to raise the bar.,, the jury is still out on that one. we shall see. There are a lot of great radios out there.. But very few have the entire eco system and solid communication channel/community that Eric and Wayne have developed with Elecraft.. Its the whole package and commitment to excellence that makes the platform great. Not the Sherwood chart. Thanks guys and keep up the good work! I Just raised the N6RO station record bar for 40 meters in ARRL DX this weekend with a K3/P3 combo... Believe me when I say this would not have been possible without this level of rig. I needed just about every receiver advantage I could to do it.

My current software configuration is to use Win4K3 ( http://va2fsq.com/ ) as the main software. It provides a panadapter scope (interfacing a Steinberg UR22 USB Soundcard to get a full 192khz spectrum) to the KX3/K3 I/Q. I then use Ham Radio Deluxe HRDLogger and Rotor Control. Win4K3 allows me to log Qs from the Win4K3 terminal into HRD and ADIF. Chasing DX, I can use the built in CW/PSK/RTTY features of Win4K3 and the KX3/K3 to chase and operate. In contesting mode, I still use Win4K3 with N1MM+. I also use cwskimmer. Win4K launches skimmer, HRD, and other apps. It will put spots from cwskimmer/wintelnetx into panadapter display. Win4K3 works with ClubLog to see your worked/confirmed to help you see if a new one in the spots is need or not. I will email you a configuration PDF. Win4K can be used in a small discrete way or to help you integrate all these other apps. I used Win4K flawlessly this weekend during the ARRL DX Phone contest to find slots to call cq/run. Need any other info, drop me a note.

If you're looking for something switchable [e.g. PK button toggles knob between A and B], I don't think Nick's firmware allows a PK function to change the PK programming. However, you could program one knob position [the switch when pushing the knob down] for VFO A control and the other for VFO B. Might also be possible to program one or more switches to select tuning rate on the K3. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/9/2015 12:19 PM, bob finger wrote: > Anyone come up with a way to control the VFO B knob (the small one) with > a Pig Knob on the K3?

Buy the P3 first. Both are useful. My primary use for the 2nd RX is diversity reception, which requires two antennas. It's most useful on the lowest bands, especially 160 and 80, but also on 40. I also use it to listen on my TX frequency when running split in a pileup. That way, I know if there's a QSO there. I can also time my calls with another station in the same pileup on that frequency. The P3 gives you a nice overview of the pileup, it allows you to monitor a "dead" band for activity (like 10M, 6M), it helps you identify RFI, it can even show you the bandwidth of dirty signals. In the E30FB pileup on 15CW this morning, K7RR was clicking almost 2 kHz wide, and the P3 clearly showed it. On 6M, I set the P3 for 200 kHz (max width), to display 50.08 MHz to 50.280 MHz. This lets me monitor for CW, SSB, and JT65/JT9 activity. I've picked up a lot of rare grids in short openings that way. Last fall there was an opening to CX and PY I made four Qs in three grids! 73, Jim K9YC From w7aqk at cox.net Mon Mar 9 17:36:00 2015 From: w7aqk at cox.net (dyarnes) Date: Mon, 9 Mar 2015 14:36:00 -0700 Subject: [Elecraft] Elecraft CW Net Announcement - the next Message-ID: Fred and all, You are correct! The Navajo Tribe does not stay on AZ time (standard time) during the DST timeframe. However, there are several reasons for that. For one thing, the Tribe itself is scattered over 3 states--AZ, NM, and UT. The biggest chunk is in AZ, but those other states do go on DST. More importantly, perhaps, is that the "capital" of the Tribe, Window Rock, is just barely in Arizona. However, for a great many things the Tribe is joined commercially at the hip with New Mexico. The biggest nearby city of any consequence is Gallup, NM, and Window Rock itself is generally served mainly from NM sources. Anything they need from an even larger city usually comes out of Albuquerque, including all (or nearly all) their professional services, etc. So, since New Mexico does go on DST, I think that makes it much more convenient for the Navajo Tribe to do likewise. I'm not sure what the Hopi Tribe does, and they are surrounded by the Navajo Tribe in AZ. That's the same issue that causes a couple of other non-DST areas to ignore their time zone in favor of what the nearest large metro center does. I think Indiana has some of this. At least one county in Oregon (my home state) is not in the Pacific time zone! that county aligns more with Idaho. I remember back in the late 50's, when I went to Ft. Knox, KY, the state of Kentucky was/is split between the central and eastern time zones (Tennessee is also). The odd thing back then was that the eastern half did go on DST (it was optional back then), but the western half did not! So, in the same state you had a two hour difference!!! That was pretty crazy! Isn't DST fun!!!

I feel blind without my P3. At a glance I can tell if the band is active or not. For example, last weekend with the DX contest and the wide open 20m, the scope was almost solid in certain spectrums. I find that I use the subRX if I am getting bored on the 75m net and want someone else to listen to. I also find it useful for tuning in the "+5" ahead of time before leaving the net with someone and making sure that it is available. I am not set up with a separate Rx antenna so I can't comment on how useful diversity Rx is. Bottom line, if I have to choose only one, I would choose the P3.

In the interest of balance ... I have a moderately vanilla K3 #642, KPA500, KAT500, and P3. I have the stock SSB filter and a 500 Hz CW filter. I do not have a SubRx. There may be some confusion lurking on the list. I have no problem whatsoever running split. I receive on VFO A which I put on the DX and leave alone. I transmit on VFO B, which I tune around in the pile-up using the "Little Knob." I decide where to park VFO B by looking at the P3 waterfall. I may occasionally want to listen to my tx QRG, I do that with one button. The confusion? You need a SubRx to do some things ... diversity reception is one example. You do *not* need a SubRx to chase DX split, operate in contests, or a variety of other operating habits. I don't know how having one would have any effect on how I operate. Initially, I bought the P3 as a toy ... last panadaptor I had was a WW2 rack-mounted monster with a 3" round screen perhaps 40 years ago. My wife has a needlepoint hobby, we have an Equal Hobby Allowance policy, and needlepoint is about as expensive as ham radio. My stuff is higher priced, but she buys a LOT more of her stuff. I have found a myriad of uses for the P3 since then, and now when operating, that's what I look at, not the radio. It is sooo very different to "see" the band rather than hear only the tiny segment where I'm tuned. Unless you have one of the distinct needs for the SubRx, and it is an either/or decision, my recommendation is the P3. I did buy the DVK for my K3 -- I have never used more than 2 memories and then only in ARRL SS SSB for my CQ and my exchange following the number. If I ever come up with another reason that works for me, I'll let you know, but for now, it is unused. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/9/2015 1:05 PM, Gary Smith wrote: > Don, > > The answer is: Yes. > > Why? > > The answer is: Well, of course. > > 73, > > Gary > KA1J > >> Okay, folks.

Both are useful. My primary use for the 2nd RX is diversity reception, which requires two antennas. It's most useful on the lowest bands, especially 160 and 80, but also on 40.

The MC; command is used only to QSY to a memory. Programming the memories using MC; and emulating button taps will be tricky. Especially if you want to deal with things like split, repeater offsets, and PL tones. It gets complicated. As Wayne suggested, you could possibly save the contents of everything (VFO A, VFO B, mode, datamode, offset, pl tone, etc) and restore them after sending the MC; command. But it won't be easy. 73,?

Problem is, it seems the way people try to work DX these days makes it virtually impossible to depend on a visual cue to know who's being worked by the DX if there's a pileup of any size at all. E30FB had the pile spread out for better than 20 kHz, and the scope showed a constant morass of signals all across the entire span. Aside from the obliviots who continually send their call whether the DX is listening or not, there are many who apparently see nothing wrong with coming back or continuing to call when the DX operator replies to a call that obviously isn't theirs. Every time E30FB would answer a complete call there were dozens of perfectly timed signals that jumped up all across the extent of the pileup. Luckily, using the second receiver I managed to stumble on to one that turned out to actually be the guy he was working. A minute or two of careful listening around that frequency revealed the operator's tuning pattern, and after just a couple of calls I was in the log too. If you really want to work rare DX these days you're going to NEED the second receiver. This isn't due to any problems with the capabilities of the P3 -- it's the result of operating practices that continue to deteriorate. You'll need all the tools you can get and all the cunning you can muster to work DX through the Doofus curtain these days. 73...

Message-ID: <008e01d05ad3$6b9c7780$42d56680$@wjschmidt.com> I have to scratch my head every time the issue of "what antenna should I use for bla bla situation" comes up on any reflector. It's similar to the question of "what radio should I use for X situation". When asked, the responses are mostly personal (as is evident by all the comments from using everything from a 52 ohm resistor at the back of the radio to a multiple stack of full-sized yagis), and sometimes even emotional. But some advice I've given my kids over the years in selecting "things" or "paths in life" is to look to see what successful people have done or used in the past. start there and build on the concept. One of what I consider to be a mentor (unknown to him of course). Doug DeMaw (W1FB). I used to always consult his articles as a young ham in the 60's and 70's. If it was good enough for him, chances are it would work for me, or at least be a great starting point. So basis the type of operating you do. (fixed or portable, contesting or DXing, High or low power, etc.), check out the people that are currently successful (or to whatever your goal is) in that area that you wouldn't mind emulating. What antennas (or equipment etc.) do they use? Of course, it's always ok to improve on what they've done. but why spend all the money and effort reinventing the wheel? What's even better, is most hams will talk ad nauseam about their stations if given the opportunity! Just a lesson from life learnings and listening. Dr. William J.

Fine job though. K1N was awful for DQRM, lids and untrained idiots. 3G0ZC the next week wasn't quite as bad, nor as rare. E30FB is rough here on the West Coast due to lack of signal strength, conditions and the same crowds. You can't hear, what isn't there. I see that problem cause as twofold: Lack of noobs seeking an Elmer for proper training NOT covered adequately in the classes or tests; Lack of folks willing to become an Elmer to guide the newcomers. That's WAY off topic for here. Putting in perspective and back on topic; the P3 was almost totally useless for K1N, except to watch and measure the height and width of the pileup (there WERE no holes to utilize in that pack). What you said is very true, the subreceiver helped, about as much because of the reasons you stated too. Together however, is still a deadly combination, by watching the (group of) signal(s) on the P3 that the DX is working, quickly tuning the receiver to the most likely being worked and confirming by ear, they allowed me to gain 13 Q's with K1N on a low dipole and some power (it's all in the DX pattern recognition, if they're not purposely avoiding a pattern). The other operating style was simply work the edges of the pileup, don't be in the middle. P3 and KRX3 in 'normal' DX collecting... fish:barrel. They are the sole reason I have 250 'entities' in the log over the last couple years. When I'm not traveling, I DX (sometimes I *am* the DX). Oh yes, the KPA500 helps, a LOT since I'm on a sole dipole. I don't see things improving in the ranks, so anyone looking at the purchase of the K Line should simply keep the budget open ended and collect everything as they can. P3 first (plan on the SVGA card too, your eyes will never improve), then a KRX3, then flesh it out with more. Let's look at your budget too. The P3/SVGA combo costs versus the KRX3 with filters (mine are all filled the same in both, for diversity and to minimize what my failing ears are subjected to when listening in two places). Add in that you'll have to replace the Synth card when you add the KRX3 (or obtain two used ones, storing the new one for later, but why) and I suspect that financially as well, the P3/SVGA will be more reachable first. That's my best reasoning for the P3 and why it should be first. It's the better of the two choices and it's more financially obtainable. Whatever you choose, good luck and good hunting.

When it is adjusted and you stay put on a frequency for a while. I disable the internal tuner when I use the loop. I find that the tuner is useful with my other portable field antennas, the SuperAntennas MP-1 and a random hank of wire. I find the MP-1 to be best when I have a good ground plane (car roof, porch railing, etc) and I am just tuning around. The random wire is great when I have the space and a tree. Each has it merits and its "issues", but when I have the loop set up and properly tuned, it is the best compromise in a portable unit.

I checked two bands 20m and 40m and got the same results. The XG3 is connected to the RX Ant and the ATU is BYPASS. My K3 has all of the latest firmware updates. SMTR MD is ABS so the preamp is OFF. I've triple checked the settings on the rig to see if there is something I missed (like RF gain) but all check out. Should the SMTR OF setting that is almost 20% off the factory default be an indication that something is amiss in the receiver gain chain?

No, my K3 is farther than that from the default. I've calibrated the S meter using the XG-3 and done the RF gain procedure. There is no issue with levels from the IF output and showing normal (calibrated) signal levels at -107dBm (S3), -73dBm (S9) and -33 (S9+40) dBm on either the P3 or SDR-IQ. 73, ...

Since you have the XG3, use the -107dBm level and measure the MDS of your K3. You can make the audio output measurements as indicated in the XG3 manual or better yet, use the dBV indication of the K3 display. If you have a receiver problem, it will show up in an MDS measurement - compare your result with the K3 spec. and/or Sherwood's MDS listings for the K3. The real determination of receiver sensitivity will be revealed by how well it can receive weak signals. The fact that your setting for the S-9 level does not agree with the default is not a large concern, especially when using SMTR MD = ABS. The factory default is for SMTR MD = NORmal. Note that all the above has to do with the K3 display S-meter reading. It has nothing to do with soundcard levels or the level of the signal on whatever software you are using for the panadapter display. First adjust the K3 for proper S-9 reading on the K3 S-meter and after that, use the soundcard gain controls and the controls in the panadapter software to adjust that applications display as you wish. There is a lot of information about the levels shown in the panadapter display at N8LP's website www.telepostinc.com. You can also signup for the LP-Pan yahoo group and ask questions related to LP-Pan and the various software applications that provide the panadapter display. 73, Don W3FPR 73, Don W3FPR On 3/10/2015 9:35 AM, engineercm wrote: > Last night I was adjusting the sound levels into my sound card from a new > LP-Pan2 and could not get to S9 using my XG3 at -73 dbm unless the preamp is > ON.

I built the 6L6 transmitter myself, so can definitely relate. Now I have the KX3, and am seriously considering the amp for it to use in the fifth-wheel. This would make it more like the K3, of course. But I have been having so much fun running QRP that I've decided to hold off on the amp. Do I use a laptop computer with my KX3 - you bet! That way I get all the benefits of the panadaptor, FLdigi, FLamp, etc. And a laptop has the added benefit of a battery (my Dell convertible using Win 8.1 gets 6-8 hours on a charge). Talk about portability - this is it! I used to have a Flex-1500, but the unreliability of the software drove me to sell it. Unfortunately I sold the 100-watt linear I had with it.

Message-ID: <3AE5C8AA7D6B4DF2A2932520B75DCF21@t30ce0d73e1b34> I recently got a new K3 and it was one of the first units supplied with the new and improved synthesizer board. In reading a few comments on the reflector, a number of people wanted to know if anyone could detect any difference between the old and the new. I also have some older K3s and decided to compare one of them head to head with the new one on ten meter CW using a 500 Hz bandwidth and check for MDS. I used the line out jack and an HP AC VTVM and 8640B signal generator. Here is what I found: K3 #8858 no preamp -137 dBm new synthesizer board preamp ON -139 dBm new synthesizer board K3 #1504 no preamp -134.5 dBm old synthesizer board preamp ON -137 dBm old synthesizer board I also ordered a pair of synth boards for one of my old K3s on March 1, but it will be awhile before it gets here I guess. I ordered a P3 kit with it and included comments that I was in no rush for the P3 so ship it all together. From the comments I have seen on how many have been ordered, I might be waiting a long time for the P3!! At my age, I'll probably forget about the order in another week or so. When it shows up, I'll wonder what it is and who ordered it!! The plan is to put new synth boards into #1504 and then I can check MDS again to see how it looks. From my checking, it looks like the newer K3 is almost 3 dB better than the older one at least as far as minimum discernable signals go. The new board definitely makes a difference, and my result tracks reasonably well with what what others have found.

I wish that were the case but my K3 has failed before and my BC-342N after only sixty years of service has developed a B+ short. On the other hand, except for replacing a noisy fan, I've never had a computer hardware failure.

On this topic, maybe I can hijack the thread but it still pertains the P3 functionality. I also occasionally travel down to Caribbean and operate CQ WW from places. I would love to have the pan-adapter handy when faced with pileups. Here are some possible benefits: - You have a visual picture of how large your pile is and it makes it easier to steer clear from congested areas. - You have a visual picture of your own TX FQ. You will know soon enough once lids start causing trouble on your TX frequency so that evasive actions can be taken. - Sometimes there is another pileup going on below or above your frequency. If the callers trying to work someone else overlap with your own,your rate takes a dive as you find yourself answering folks who are actually not calling you. In my case, P3 is too big (volume-wise) and there is no space to fit it in carry on suitcase along with K3, PSU, Cables, Laptop, Keyer etc. By looking at parts list from P3 manual, perhaps we can significantly shrink the depth of the unit by making the Top, Bottom and Side panels (E100362, E100363, and E100361) shorter if Elecraft would be willing to manufacture and provide such kit. We always have an option to use the hacksaw but it would not look pretty :-) 73, Nick ve3ey On Mon, Mar 9, 2015 at 9:59 PM, Rick WA6NHC wrote: > You're preachin to da choir son.

As one of the early adopters of the KX3 and later the PX3, I have a high regard for the excellent Elecraft customer service and quality of engineering. Whenever I am doing portable operations, I carry the KX3 along with a spare LiPO battery (e.g. Field Day or hikes). I am also the owner of a FlexRadio 6700. It is my home station rig along with the Alpha 9500. I have had the Flex for 6 months and am very pleased with it. It replaced my TenTec Orion II and functions well on many, many modes. I operate CW 98% of the time. I am delighted to be able to choose knob radios (SDR nonetheless) from Elecraft AND software HMI radios from FlexRadio. Both are excellent American ham radio firms.

I just had to have one. Three months later I just had to sell it because I realized that reliability was compromised when more than one piece of gear was needed for a task that used to be handled by a single piece of gear alone. Not only that, but I could not effectively use my computer for other tasks because it was needed to run the radio. I still use a computer along with my radio for ham related activities but I sleep better knowing I can still engage in ham related activities when my computer gets sick. Computers tend to get sick more often than radios. At least that has been my experience. Besides,I don't want to give up complete control of my radio to a computer.

In reading a few comments on the reflector, a number of people wanted to know if anyone could detect any difference between the old and the new. I also have some older K3s and decided to compare one of them head to head with the new one on ten meter CW using a 500 Hz bandwidth and check for MDS. I used the line out jack and an HP AC VTVM and 8640B signal generator. Here is what I found: > K3 #8858 no preamp -137 dBm new synthesizer board > preamp ON -139 dBm new synthesizer board > K3 #1504 no preamp -134.5 dBm old synthesizer board > preamp ON -137 dBm old synthesizer board > > I also ordered a pair of synth boards for one of my old K3s on March 1, but it will be awhile before it gets here I guess. I ordered a P3 kit with it and included comments that I was in no rush for the P3 so ship it all together. From the comments I have seen on how many have been ordered, I might be waiting a long time for the P3!! At my age, I'll probably forget about the order in another week or so. When it shows up, I'll wonder what it is and who ordered it!! The plan is to put new synth boards into #1504 and then I can check MDS again to see how it looks. From my checking, it looks like the newer K3 is almost 3 dB better than the older one at least as far as minimum discernable signals go. The new board definitely makes a difference, and my result tracks reasonably well with what what others have found. > > Dave K1WHS From elecraft at mailman.qth.net Tue Mar 10 17:05:34 2015 From: elecraft at mailman.qth.net (Doug Person via Elecraft) Date: Tue, 10 Mar 2015 15:05:34 -0600 Subject: [Elecraft] Flex VS K3 In-Reply-To: <54FEEBE1.2000907@mediacombb.net> References: <9E1748497DCDA342A28EFCAB1C82CE58015B77A8@SVNT6-4.inepar.com.br> <51AE04A6.9030002@w2blc.net> <1370363759.95598.YahooMailNeo@web181005.mail.ne1.yahoo.com> <51AE1EC6.5090700@w2blc.net> <1370366602.85539.YahooMailNeo@web181002.mail.ne1.yahoo.com> <1370372919.83064.YahooMailNeo@web120304.mail.ne1.yahoo.com> <003901ce620b$5b0af490$1120ddb0$@net> <1370452578.89122.YahooMailRC@web181604.mail.ne1.yahoo.com><1370456288.38951.YahooMailNeo@web160201.mail.bf1.yahoo.com> <54FCDFB1.6050509@audiosystemsgroup.com> <54FD17EE.40609@triconet.org> <54FDC90B.5010607@audiosystemsgroup.com> <54FDE479.4050202@subich.com> <54FEEBE1.2000907@mediacombb.net> Message-ID: <54FF5C9E.2010203@aol.com> This so-called minimum was state of the art 8-10 years ago.

I put Windows 7 on it because it is stable and I like it. I have no idea about Vista, I have never used it. This new box runs in conjunction with a "headless" Ubuntu 14 server for network attached storage and the repository for Subversion. My old computer will soon be set up the same way for even more attached storage. With most of the files off loaded to the servers my CPU rarely gets to 50% usage and then only when I run multiple instantiations of a variety of my simulations. There is no lag now which is greatly appreciated. So state of the art has changed quite a great deal from your minimum standard. This describes my ten year old machine except for the fact it had dual video cards to power four monitors. 73, Kevin.

A Microsoft Skydrive, or a Google update program, or one of a large number of other stuff, would periodically issue an interrupt that would take the CPU's attention away from the Flex data stream, introducing latency and/or crashes. The first design was a recipe for obsolescence. Besides, if you wanted PSDR, a K3 with LP-Pan and NaP3 has a superset of the capabilities of a Flex 5000, and none of the endless series of bugs that plagued the Flex version of PSDR. The new Flex stuff brings the data path inside the radio, so that the dependency on the OS is reduced, and it probably works okay if you want to try to operate your station with the mouse. But at least IMHO, a DXer working split in a big CW pile without knobs is at an overwhelming disadvantage. 73, Tony KT0NY From elecraft at mailman.qth.net Tue Mar 10 19:09:10 2015 From: elecraft at mailman.qth.net (Mel Farrer via Elecraft) Date: Tue, 10 Mar 2015 23:09:10 +0000 (UTC) Subject: [Elecraft] BC-342 and 6L6 In-Reply-To: <54FF466B.2040006@socal.rr.com> References: <54FF466B.2040006@socal.rr.com> Message-ID: <1192520037.830752.1426028950765.JavaMail.yahoo@mail.yahoo.com> Somewhere around 1956 I acquired a BC342 without a AC power supply because the Dyno made way to much noise.?

I guarantee it. So....you get to buy a top of the line high performance PC to run your radio. I find it interesting that nowhere that I've seen does Flex give a minimum requirement for om-board memory. I had a Polycom salesman try that while selling us an H.323 video conferencing system. I couldn't get the man to tell me exactly how much of my T1 connection to home office in Green Bay was going to be used for our daily teleconference. Finally got a ridiculous number out of him (256 Kb/s). The truth was 3X that much, half my T1 while trying to send real time data to GB. Now I always multiple minimum retirements by three....four if it's Microsoft, Cisco, or Polycom. Windows 7 and Vista need 4G of memory to run well. There is a difference between running well and running. How much memory does SmartSDR require to run well? I couldn't find it but I couldn't spend an hour looking. That number isn't a sales bullet point on the Flex website. Hmmmm, makes me wonder. Maybe it's just me. After a long day of dealing with the machinations of MS, IBM, VM Ware, Cisco, Barracuda, Dell and HP, all day along with 700 users who sometimes I'm convinced are UN-trainable, All I want to do is lay my hands on a radio, even though I know it's mostly firmware, and not another keyboard.

I still paper log, and automated spots do not excite me - I can bring up the spots on the computer and then dial the K3 to that frequency should I be so inclined. It causes me to think about what I am doing in the hamshack. Those hams who arbitrarily click on spots do not excite me. I prefer to hear the DX first rather than just transmitting without regard to others just because a spot says there is something of interest at that frequency. In other words, if you can't hear them, don't transmit - the ham bands would be much more sane if everyone did likewise. Just my not so humble opinion. 73, Don W3FPR On 3/10/2015 7:17 PM, Kevin Stover wrote: > You can't see Internet spots or balance your checkbook or read the > Elecraft reflector and run that "radio" at the same time.

It consisted of two of those Bud aluminum boxes. Box 1 had a cord to plug into the wall, two switches, and two single wires coming from each end. It weighed about 1/4 of a brick. The two single wires went into the ends of Box 2 which had two #47 dial lamps poking through rubber grommets on top. It weighed almost nothing. Plugged in, Switch 1 turned Lamp 1 on and off, Switch 2 turned Lamp 2 on and off. We hacked 1/4 of a brick off and put it inside Box 2 with duct tape. You could have both lamps off, one or the other on, or both on, however binary arithmetic had not yet arrived in Los Angeles and we failed to sense the significance of that. Convinced we were going to stump everyone at the meeting, we brought it out during the coffee break before the raffle. None of our teen friends could figure it out. The OT's remained silent but smiled a lot. We finally said we'd give them a hint. "Box 1 contains a transformer, two switches and two solid state diodes," just then coming onto the market. "Box 2 contain two more diodes, two lamps, and 1/4 of a brick." Still no one could draw the circuit, so Terry did for them. They asked, "What's the 1/4 of a brick for?" Terry said, "To make it seem substantial." Rather than put a brick inside my P3, I put two little squares of double-stick automobile moulding tape under the two front feet to keep it planted on the shelf. While I'd like to think Elecraft has a whole bunch of cool electronics and features to make use of all that empty space about to be released, I suspect it is as long as it is so it would keep the K-Line symmetric when lined up on the desk. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/10/2015 4:14 PM, Harry Yingst via Elecraft wrote: > You could always put a block or bag of lead inside > > > From: Wes (N7WS) > To: elecraft at mailman.qth.net > Sent: Tuesday, March 10, 2015 1:39 PM > Subject: Re: [Elecraft] (Mini)P3 v SubRX > > Lyle, KK7P, demoed a pre-production P3 to our DX club.

Since getting back on the air in 2003, I've always had a laptop in the shack. It great at taking care of the routine stuff, like day to day logging. With the push of a few buttons, I can upload my log to LOTW and eQSL. When I enter a call, I can see vitals for previous QSOs if I want them. When I hear a DX station (or see a spot), I can immediately see if I "need" a QSO for some goal. LOTW and eQSL mean that I only need to send cards to guys who really want a paper card. That sames me a LOT of time. It also saves me a lot of time and money if I need confirmations for awards. All of that is without rig control, without digital operation, without contesting, just logging and log-related stuff. I view the shack computer as making my life easier, freeing up my time to play radio, upgrade the antenna system and the station (or repair it), and so on. 73, Jim K9YC From wb4jfi at knology.net Tue Mar 10 19:52:22 2015 From: wb4jfi at knology.net (wb4jfi at knology.net) Date: Tue, 10 Mar 2015 19:52:22 -0400 Subject: [Elecraft] TS-990 In-Reply-To: <54FEFD29.2030506@subich.com> References: <54FEEBE1.2000907@mediacombb.net><1157610268.1738200.1425995409632.JavaMail.yahoo@mail.yahoo.com> <54FEFD29.2030506@subich.com> Message-ID: <769FDC38175C4F12A750232D0132DDC3@tfoxserver3> My goodness! So, now a Flex is nothing more than an expensive sound card? I wonder what happens when the K3 CPU goes squirrely, or the FP LCD has an issue. Or a software upload/upgrade causes the K3 to brick itself? Or a FP switch/button/control goes bad? I've seen these issues on the reflectors before, and just as bad as a computer problem. Maybe worse, as the K3 hardware is not necessarily off-the-shelf, and software source not available. Elecraft does a GREAT job to offset these problems, but shipping stuff across the country takes longer than going to the local Best Buy/Staples/local computer store. Hey Joe, you still watching NTSC television as well? Or is that black and white KoolAid still in control? I've got a K3/P3/SVGA, a KX3, a Flex 6700, an SDR-1000, an openHPSDR rig, an SDR-IQ, an SDR Cube, a HiQSDR, an STM32SDR, and several SoftRocks. And an FT-817. I like them ALL! My main rig is the K3, it works really, really well. I LOVE IT! The KX3 sees portable operation. The Flex allows me to see multiple bands at once, and/or more of one band than the K3/P3 does. The Flex 6x00 is also becoming a much more integrated digital radio, thanks to keeping ALL the demod sampling as digital, as it interfaces with FLDIGI, etc... programs. The K3 must still use analog audio interfacing, unless you use the internal decoder/encoder. Couldn't one argue therefore that the K3 is only an analog radio, based on this one weaklink? I am certainly NOT doing that, but it's as ridiculous as saying the Flex is NOT a radio. The Flex 6x00 series actually uses the newerSmartSDR software, that source is not publicly available. The older PowerSDR did have its source code available. Can you get the source code for the K3 or KX3? Not that I'd ever want Elecraft to do that! NO!!!! But, that's another point that Flex had. With the new synth, Elecraft just proved that their already wonderful radio CAN BE significantly improved. Congrats to them! Good Job! I love seeing an improvement like that, regardless of the platform. Elecraft is paying attention to both its hardware AND software/firmware. I SEE NO REASON TO TRASH ONE TYPE OF RIG FOR ANOTHER. Those that disparage one brand over another are likely insecure with their prior purchase decisions. Over the last two decades or so, it was Yaesu vs Kenwood vs Icom. At least now it's one SDR versus another. YES, the K3 IS generally considered an SDR, even by the original K3 software engineer. How about giving this product bashing a rest fellows? Implying a Flex is not a radio is just going too far. It shows personal bias and thick-headedness to the extreme. And BTW, there's this new thing called "Cable TV", and some future stuff called "streaming video" that may impact OTA TV. I'm keeping an eye on these new technologies as well, even though I've spent over 30 years as a broadcast TV engineer - and corporate engineering director, responsible for only 23 OTA TV stations throughout the country (including during the DTV transition).

You say power lead appears to be OK. Appears??? How did you come to that conclusion? If you placed your hand on the cable and said it is not hot and therefore concluded the cable appears OK you have again missed the point. At low voltages (and high currents) the quality of the cable (and connectors) is determined by the voltage drop. Additionally the voltage read on the front panel is read through a poly fuse which has a voltage drop that is greater than the voltage seen by the 100 watt amplifier which is alternatively feed through a 22 amp circuit breaker. The current that passes through the poly fuse is further regulated down to 5 volts so the voltage drop across the poly fuse is immaterial but it does represent an insignificant error that the 100 watt amp does NOT see. Ergo where you measure your voltages is all important to your pass/fail calculations. What to do? Measure the voltage at your power supply and then again at the K3 circuit breaker. If the difference is more than 0.5 volts I would use a heaver power lead. 73, Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of G4FNL Sent: Sunday, March 08, 2015 4:24 AM To: 'Robin Moseley'; 'Elecraft Reflector' Subject: Re: [Elecraft] K3 voltage indicator Guys I may need to re-enforce my power lead and connections - but they appear OK.

I made an assumption that if the IQ signal wasn't were it should be using a S9 signal, something must be wrong with the K3. Silly me. After putting SMTR MD back to NOR and using the Preamp (according to the Manual), the S meter was showing S9 to agree with the input signal from XG-3. So, back to the Telepost procedure for LP-Pan. What could I be doing wrong? Simple--had the Sub receiver ON which drops the signal by 3DB. Turning it off and the signal being ready by the digital meter popped up into the zone I expected. Now I have enough headroom for whatever comes my way. Learned a few things about the K3 I didn't know before. I love this radio stuff!

It wouldn't be hard to shorten the ribbon cable. If you're careful you could remove and re-use one of the connectors, install it near the other, and cut off the excess cable.

While it only gives a 3 or 4 khz spectrum, it is helpful, so I was able to find that "hole". Oh, yeah, I was running one watt, so there was a hole. So I guess I vote for the sub rx first.

In-Reply-To: References: Message-ID: Nate, I'll preface this by stating that I'm the repeater coordinator for Montana, and a retired career 2-way radio tech. It's common for repeaters to require a CTCSS tone for access, but is -very- rare to find one in the amateur world that also transmits the CTCSS tone. Out of almost 300 I have in Montana I'm aware of none. The ARRL Repeater Directory lists the tone required if it's needed for accessing a repeater. Yes, one can listen to the station that's accessing the repeater and perhaps ascertain the frequency of the CTCSS tone, but this is difficult to do since the tones are in the sub - audible range. There -are- scanners and amateur transceivers that can do this and of course professional test equipment. BTW ... CTCSS stands for "Continuous Tone Coded Squelch System". The tones are standardized and are the same for all brands of 2-way radios but each has their own trade marked names ... (Motorola = PL / Private Line), GE = CG / Channel Guard), etc. A Google search will tell you more..... 73 Ken - K0PP From w7aqk at cox.net Tue Mar 10 22:54:30 2015 From: w7aqk at cox.net (dyarnes) Date: Tue, 10 Mar 2015 19:54:30 -0700 Subject: [Elecraft] (Mini)P3 v SubRX Message-ID: <39080D104A91495394FC3C609C795281@TDYDell> Hi All, That modified (cut down) version of the P3 by WA6KBL is quite intriguing. Someone else has suggested that doing this could cause some interference action with the display, which is too bad if it is true. It seems to me that, since the PX3 works fine in a smaller enclosure, why wouldn't the P3 work O.K. as well? Personally, I wish the P3 had less bulk, particularly since it seems excessive and clumsy. I know the P3's dimensions were determined, at least in part, to correlate to the K3's dimensions. However, so much wasted space would be nice to eliminate if possible. Some time back, a friend of mine was casually asked whether he and his wife did much cooking at home. After a brief pause, my friend's tongue in cheek response was that "We store very valuable documents in our oven!" That's sort of how I felt about my old Orion II, which is (in my view) enormously oversized, and takes up a lot of desk space. There is a lot of empty space inside. Same goes for the P3 I now have. The width and height are fine, which accommodates the display size, but the depth is seemingly excessive, and not by just a little bit. I suppose some would say that the additional room you might gain by having a reduced sized P3 would just be dead space anyway. However, I think a smaller version would add significantly to the portability and handling ease of the unit without any sacrifice in utilization--assuming the interference concerns are unfounded. Even the modified version by WA6KBL doesn't cause things inside to seemingly be cramped. I've traveled with my K3 several times, but I have never taken the P3 along, and mainly because I thought it was just too much additional bulk. I might feel differently if my P3 was more in line size wise with the WA6KBL version. So, if Elecraft feels they could offer a modified enclosure kit, I, for one, very well might be interested. It looks to me like it might just be a matter of providing shortened top, bottom, and side plates. The back plate could be preserved. Would this be all that expensive or problematic to do???

In reading a few comments on the reflector, a number of people wanted to know if anyone could detect any difference between the old and the new. I also have some older K3s and decided to compare one of them head to head with the new one on ten meter CW using a 500 Hz bandwidth and check for MDS. I used the line out jack and an HP AC VTVM and 8640B signal generator. Here is what I found: >> K3 #8858 no preamp -137 dBm new synthesizer board >> preamp ON -139 dBm new synthesizer board >> K3 #1504 no preamp -134.5 dBm old synthesizer board >> preamp ON -137 dBm old synthesizer board >> >> I also ordered a pair of synth boards for one of my old K3s on March 1, but it will be awhile before it gets here I guess.

From the comments I have seen on how many have been ordered, I might be waiting a long time for the P3!! At my age, I'll probably forget about the order in another week or so. When it shows up, I'll wonder what it is and who ordered it!! The plan is to put new synth boards into #1504 and then I can check MDS again to see how it looks. From my checking, it looks like the newer K3 is almost 3 dB better than the older one at least as far as minimum discernable signals go. The new board definitely makes a difference, and my result tracks reasonably well with what what others have found. >> >> Dave K1WHS > > ______________________________________________________________ > 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 n6kr at elecraft.com From JimMiller at STL-OnLine.Net Wed Mar 11 02:04:33 2015 From: JimMiller at STL-OnLine.Net (Jim Miller) Date: Wed, 11 Mar 2015 01:04:33 -0500 Subject: [Elecraft] K3 - K144XV Output Power Range Message-ID: <010401d05bc1$3f484120$bdd8c360$@STL-OnLine.Net> Will the 1mw calibration have an effect on power output from the K144XV?

In-Reply-To: References: Message-ID: <54FFE31B.6060303@gmail.com> Hi Ken, It may be that way in Montana (one of my favorite places in the summer) but it's not that way in CA. Output tones on a repeater are common here because of the repeater density (simple proximity, co-channel or by distance) and because summer ducting is common. It's a poor mans noise filter. Many of our 'communities' are larger than Billings or Helena (together) and the cities are obscenities. The RF noise floor can be rough. Using output tones on a repeater makes a huge difference for users. Even where I live, in suburbia, the local club uses an output tone on all of our repeaters (6, 2, 220, 440 and 900) and there is no other 2M channel user for 200 miles, rare here. I'd bet that most metro areas of size (DFW, NYC) also use output tones on ham repeaters. It's a simple means to lower user irritation from other radio systems. We're starting to see more DPL used as well. No, to the original poster, the K3 does not listen for tones. I'm sure it could be added, but frankly I'd rather the team works on other things. Use of tones on 10/6M (stock K3 feature) repeaters is common here and the percentage of folks using 2M transverters for repeaters is a small percentage of the whole. There isn't much demand or return on engineering time to change the K3 to decode. I use a commercial radio on 6M repeaters (except when remoting from my station while traveling) and a dual band radio for 2M/440. It's simpler in the long run and they have the decode features, plus I can listen to the local DX repeater without tying up the K Line. ;o) 73, Rick wa6nhc From pincon at erols.com Wed Mar 11 09:00:29 2015 From: pincon at erols.com (Charlie T, K3ICH) Date: Wed, 11 Mar 2015 09:00:29 -0400 Subject: [Elecraft] [K3] Scanning for repeater tones.

Makes for a LOT less noise in your radio from local squelch breaks. We also use CTCSS tone squelch on simplex as well.

But, even with the DX Cluster up in the background, many times I just sit listening to a randow frequency or watching the RF spectrum of my Win4K3 driven scope powered by a K3 or KX3. I can't tell how many times I've been on some random frequency with nothing going on, and then someone pops up and calls CQ or asks if the frequency was in use. Just last night, BD9XE/QRP popped up last night on a random 20m cw frequency and I worked him before he was ever spotted. In this way, I learn about propagation openings, propagation timing, and such. When it comes to radios, the thing that excites me about the K3 and KX3 rigs are that you can operate using knobs or software. The Elecraft K3 and KX3 rigs gives you the best of many worlds...and over time the gear keeps getting better. *Back to different strokes for different folks*...A radio buddy, K3FK was asked by a reporter at our Field Day event in 2013, and I paraphrase, "what is it about ham radio that interests him", he answered "what is it about catch and release fishing that attracts people?"

Yes, I have a 6 core AMD computer with 8GB of memory dedicated to the ham station, but I do not use it a lot for rig control - its main use right now is to give me a panadapter display, but that part will soon be replaced by a P3. I still paper log, and automated spots do not excite me - I can bring up the spots on the computer and then dial the K3 to that frequency should I be so inclined. It causes me to think about what I am doing in the hamshack. Those hams who arbitrarily click on spots do not excite me. I prefer to hear the DX first rather than just transmitting without regard to others just because a spot says there is something of interest at that frequency. In other words, if you can't hear them, don't transmit - the ham bands would be much more sane if everyone did likewise.

Catch and release fishing. So, you can sit quietly by the stream and wait for a rise or use a full color fish finder while trolling. I like to do both styles of fishing and both forms of radio operation. Both take skill and a knowledge of how to use the basic tools. To each his own, because the one thing we won't hold back is the rate and pace of innovation. Might as well enjoy whatever is in front you and roll with the changes. For what it is worth, at least the guy operating from a spot probably got the split set correctly via the automatic QSX features offered by many programs. Many "Old Schoolers" still can't get that correct (Just some levity and not a poke at anyone). I make that mistake all the time when I stumble upon a new one starting up split. 73, Todd. -- View this message in context: http://elecraft.365791.n2.nabble.com/Re-TS-990-Don-Wilhelm-tp7600124p7600132.html Sent from the Elecraft mailing list archive at Nabble.com.

Technically that means fast settling, no overshoots, no skipped steps or resorting to a higher tuning step even when tuning fast.

It is probably picking specs out of the pepper , but it seems to me that testing a K3 around 5300 khz means there is essentially no benefit from the ham band bandpass filters the K3 uses - Would like to see those numbers compared for instance with the 3880khz or whatever freq it was with a filter in a ham band.

The sub-receiver in my K3 is equipped with a 2.7 5 pole filter in position 1, and a 400Hz 8 pole in position 5.? All works well until I narrow the bandwidth to 400 Hz, then the sub-receiver goes quiet (the main continues to work normally.)? I used the K3 utility to set filter 5 bandwidth both narrower and wider, and wherever it is configured is where the receiver goes quiet. I can't find anything in the archives about this particular problem, but thought I would seek the group collective wisdom before tearing into the radio.?Thanks, Chuck Teague, NN7U From n6kr at elecraft.com Thu Mar 12 12:27:33 2015 From: n6kr at elecraft.com (Wayne Burdick) Date: Thu, 12 Mar 2015 09:27:33 -0700 Subject: [Elecraft] Noise Power Ratio and the K3 with new synthesizer?

At times, I find it difficult to zero in on a station's 600-hz with my "600 hz" squarewave. Has someone come up with a mod? I'm thinking that plenty of audio is available at the sidetone level setting (STL), so it might be possible to make an RC filter.

When repeaters send CTCSS tones, many radios depend on the poor low frequency performance of small speakers to suppress the audio tone. This approach fails when using a car audio system to get enough volume to overcome wind noise etc. Having a fairly steep rolloff below 300 Hz available would help with this situation. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | "The only thing we have to | Periwinkle (408)356-8506 | fear is fear itself." - FDR | 16345 Englewood Ave www.pwpconsult.com | Inaugural address, 3/4/1933 | Los Gatos, CA 95032 From jbollit at outlook.com Thu Mar 12 13:49:12 2015 From: jbollit at outlook.com (jim) Date: Thu, 12 Mar 2015 10:49:12 -0700 Subject: [Elecraft] Noise Power Ratio and the K3 with new synthesizer?

I found one thing that maybe of interest I found when I ran it if the real time clock is on it takes about 3 minutes to run vs. the real time clock off it takes about 2 minutes 15 seconds. While the time difference is insignificant, the advantage of running with the real time clock is you do not get all the time print out. You do have to hit the menu button, after you run the parameter program with the real time clock off after the program says Done. On a different note, I can run the program fine from the web site, but I need directions on how to run the program off line. Could someone contact me off line and lead me step by step how to run the program off line. I am sure the reason I cannot get it to run off line is something simple.

I have no room to have a logging program running when I do eme - paper and pencil are simple - so is the eraser! Regarding my wife: Her (old duo-core P4 got so slow, I offered to rebuild it for her). But she went and bought a new i7 laptop before I got it rebuilt and that is what she uses. The rebuilt desktop is left turned off. She probably does 70-80% of her time using the ipad-3 (face-time and e-mail, oh and puzzles). Like I said what would she use a new desktop, for? If she gets a new desktop, I will seize the old desktop for doing something (dedicated auto-tracker? making coffee?). She has a Kindle-Fire (I got the old original Kindle - which is used more than she uses the fire). I just went thru FL-digi changing several macros for specific eme scripts. I am going to use it for keyboard CW when doing CW-eme (I verified I could copy CW audibly when the K3 is in DATA-A mode - required by FL-digi). The dusty shelf hold my Pac-Bell P100 40MB win95 and an old Dell desktop (upgraded to 512MB and XP32). Both probably headed to recycle. I'll keep the old IBM thinkpad P90 since it has a working FD drive and add-on DVD.

On this topic, maybe I can hijack the thread but it still pertains the P3 functionality. I also occasionally travel down to Caribbean and operate CQ WW from places. I would love to have the pan-adapter handy when faced with pileups. Here are some possible benefits: - You have a visual picture of how large your pile is and it makes it easier to steer clear from congested areas. - You have a visual picture of your own TX FQ. You will know soon enough once lids start causing trouble on your TX frequency so that evasive actions can be taken. - Sometimes there is another pileup going on below or above your frequency. If the callers trying to work someone else overlap with your own,your rate takes a dive as you find yourself answering folks who are actually not calling you. In my case, P3 is too big (volume-wise) and there is no space to fit it in carry on suitcase along with K3, PSU, Cables, Laptop, Keyer etc. By looking at parts list from P3 manual, perhaps we can significantly shrink the depth of the unit by making the Top, Bottom and Side panels (E100362, E100363, and E100361) shorter if Elecraft would be willing to manufacture and provide such kit.

This should be easy with RXEQ. It's also good practice to roll off the lows on FM TX for the same reason it's good on the HF bands. While the lows don't burn more power with FM, they do use up deviation that would better served by voice range, so the practical effect is the same. 73, Jim K9YC From keith at compassmarina.com Thu Mar 12 17:22:28 2015 From: keith at compassmarina.com (Keith D Jones) Date: Thu, 12 Mar 2015 17:22:28 -0400 Subject: [Elecraft] PX3 Stand Message-ID: <000601d05d0a$a58690a0$f093b1e0$@compassmarina.com> I bought the SOTAbeams low rider stand for my KX3 and when I got the PX3 I inquired with Richard G3CWI if one would become available.

(2) the KXPA100 would not come on; in trying to track it down, I observe that the PA mode in the KX3 was OFF; setting it to ON, the KXPA100 turns on, and the Sys Fault LED flashes, then it turns off the KX3 PA mode and itself OFF.

The issue is that Adam's data is flawed in at least two ways. The notch is wider than the SSB filter which means the noise is not being applied to the product detector or DSP ADC. Second by reducing the noise level for DDC receivers, they are not being fairly tested for the same level of total noise power. There are also questions about the effects of roofing filters of different bandwidth - to what degree do they change the total noise power applied to the entire receiver chain (including the product detector or DSP ADC)? Secondly, what are the effects of AGC ahead of the product detector/DSP ADC and does the noise power testing really measure dynamic range or is MDS compromised by the AGC? With a 3.3 KHz notch, the only way Adam can fairly test receivers is with a 6 or 15 KHz roofing filter. If he truly expects to test SSB performance, the notch width needs to be less than half the width of the SSB filter. Secondly, receiver MDS needs to be measured with the noise present to rule out AGC desensitization. BTW, Adam's MDS measurements for the two K3s he tested are off by 6 to 9 dB compared to both Sherwood and ARRL Labs while his MDS values for Icom are within 2 dB of ARRL Labs. There is something very unequal about the testing of the K3. 73, ... Joe, W4TV On 2015-03-12 9:26 PM, Johnny Siu wrote: > Hello Scott, > I am afraid I do not agree to your comments.

Fortunately my troubleshooting was very easy because my K3 would 'de-sense' every time I would switch from my tri-bander to my 40m yagi. Poor weather proofing at my antenna switch at the TOP of the tower was the culprit. Thus...NEVER put an antenna switch at the top of your tower plus weather your connections once and then go back and do it again! 73, Tom - W4BQF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Frankie Hunt K4TEN Sent: Friday, March 13, 2015 8:36 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 Receive De-sense Problem I had those exact symptoms, except with a different radio and band.

The PX3 problem of not turning on HAS been an issue and I am sending it back to Elecraft today for them to look at, actually. In my case at least, there is definitely a temperature relationship to the problem. The colder it is the harder to get it to turn on - sometimes many pushes do it, sometimes not.

Well, suppose the isolation between ANT1 and ANT2 is 50 dB. A signal from your friend that would have been 30 dB over S9 on ANT1 would show up at S5 or S6 on ANT2 due to the -50 dB bleedthrough. In the other direction, you were transmitting into a high SWR. To protect itself the transmitter would have folded power back to some low level, and on top of that there would still be the 50 dB of isolation between the transmitter and your antenna, so perhaps it's not so surprising he couldn't hear you even though you could hear him. 73, Rich VE3KI From rpfjeld at outlook.com Fri Mar 13 13:45:40 2015 From: rpfjeld at outlook.com (Richard Fjeld) Date: Fri, 13 Mar 2015 12:45:40 -0500 Subject: [Elecraft] K3 Receive De-sense Problem In-Reply-To: <1426250139384-7600192.post@n2.nabble.com> References: , <1426250139384-7600192.post@n2.nabble.com> Message-ID: I have found the center conductor on certain PL-259 plugs is slightly smaller than others.

It would be intermittent center conductor connection with capacitive pass-through. Desense would follow some external transmission pattern. Yours sounds more like a mechanical or corrosion based intermittent. If you own a K3, blame it dead last after you have triple-checked all other possible sources. The odds are way against the K3 being the problem. If the K3 is at fault you should be able to see it with only a wire connected to the chassis connector as a signal source. Coax patch cables are a long-time, NOTORIOUS source of problems. From the long experience of many, there is nothing redemptive about patch cables that should give them a free pass looking for trouble. Hams will use an old one because they don't want to make a new one. Also problematic are non-Amphenol coax elbow adapters which have a spring internally to go around the bend. The spring contact becomes corroded if QRO has EVER been used on them or they have EVER gotten damp. Amphenol's have the male pin internally threaded to screw into the line from the female end. This process makes it more expensive to manufacture, hence the more common cheep-cheep versions with the spring. They work ok OUT OF THE WEATHER with CB and RX only, and probably OK with 100w. But getting damp or running QRO will corrode the female-spring-male center conductor connection. Hams should THROW AWAY any spring-based elbow adapter, and only purchase Amphenol elbows. If there is a non-Amphenol in the shack, you will likely use it and forget that you did until it goes bad. You can go around a hamfest and pick up a dozen Amphenol elbows inexpensively. The Amphenol's are good forever. Older PL259's had a longer shell, and some manufacturers of new equipment have gone to mounting the SO239 chassis connectors with the flange INSIDE the chassis/case. Then the longer shells then cannot firmly force the pin and spline to mate, and you will have intermittent connection. THROW AWAY any PL259 with the longer shell or with anything other than teflon as a center insulator. Replace them on any patch cord. A K3 is almost never the source of intermittents. 73, Guy.

Unless you're one of the fortunate amongst us who have both the test equipment and experience to do all the necessary updates/upgrades, the cost of sending your rig back to Elecraft is very little and while you'll obviously have to pay more to have it done there than do it yourself, IMHO it is worth the time and $ to have your rig made to today's standards. I'd sent my K3 (Serial # 2382) back about a year ago for all the updates/upgrades. What I didn't do was have them put in the voice recorder and I should have had them do that while the rig was apart. Last month I replaced the Synthesizers and with that I now have a K3 that is every bit as good as a new K3. While it does cost a bit to keep it updated, I'm happy knowing that it passed the factory's blessing when it was shipped back to me and all is in calibration and working 100%. Not having to buy a whole new radio when I want to upgrade is fantastic and I'm happy to keep current bit by bit in an affordable fashion. I take my car to the shop annually for a check-up so it will keep running as new, it only makes sense that my radio should be given a check-up at the factory every several years and have them do anything new that has become desirable since its last visit.

The K3 is around .9-1.2 A, for the same reasons. To put these values into perspective: most modern desktop transceivers (many with performance ratings far below that of the K3) draw more like 2 to 4 amps in receive mode. > ?what is in the K3 that requires 4x more current? What do the additional current consumers contribute to the operation of the radio? The K3 has the following stages that add both current and features or performance advantages: - high-dynamic-range, dual-conversion superhet architecture with heavily biased mixers, post-amp, etc. - multiple stages of high-bias PIN-diode T/R switching and other PIN-diode path switching - high-performance 32-bit DSP I.F.s for main and sub receiver - large, brightly lit LCD with dual VFO displays, alphanumeric display for text decode, etc. - four multi-function encoders, each with two LED indicators - ATU that uses non-latching relays to maximize tuning speed - digital voice recorder (DVR) - high-power stereo AF amplifier - misc. support and I/O circuitry (not found on the K2) This isn't a comprehensive list, but you get the idea. Yes, it's more current drain than a K2, but we were able to provide excellent performance and a wide range of features in the K3 while consuming 1/2 to 1/4th the current drain of most transceivers in its class. The KX3 is another interesting point of comparison. Its receive current drain is about 200-250 mA, typically, while providing the highest performance of any ultra-compact transceiver by a wide margin. 73, Wayne N6KR From w7ox at socal.rr.com Fri Mar 13 15:13:01 2015 From: w7ox at socal.rr.com (Phil Wheeler) Date: Fri, 13 Mar 2015 12:13:01 -0700 Subject: [Elecraft] WTB: KPA100 & KAT100 In-Reply-To: <3B785A3D-C119-482E-ACE4-B3D2DBBBF04E@gmail.com> References: <3B785A3D-C119-482E-ACE4-B3D2DBBBF04E@gmail.com> Message-ID: <53FC3F7C-2820-4631-A4D2-795AF9649F0E@socal.rr.com> I'm with Matt on this.

Gary, We've been shipping the K3 since 2008. Things do wear out, sometimes, with products that get nearly continuous use (like K3s). We strive to locate and ship the best-quality parts we can that are compatible with the existing PC boards. And we do improve module designs as time permits. That said, you seem to have an extreme case. If you don't want to incur the cost of having us make these simple repairs or mods, perhaps you can find someone locally in VK--a PC or appliance repair shop, maybe even another ham with the needed tools. We can put together a package deal on all of the parts you think are required to bring your K3 back up to full health. I'll see to it that you're given pricing commensurate with your long history as a K3 owner. 73, Wayne N6KR From iwesterl at bigpond.net.au Fri Mar 13 18:34:02 2015 From: iwesterl at bigpond.net.au (Ian Westerland) Date: Sat, 14 Mar 2015 09:34:02 +1100 Subject: [Elecraft] Hello and a question Message-ID: <20150313223420.NKEU3884.nschwmtas06p.mx.bigpond.com@nschwcmgw06p> Hi!

That means even if you have selected ANT2 but do not have anything connected to ANT2 you might still hear signals from ANT1 if they are strong enough. 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 13.03.2015 um 14:17 schrieb Mike Reublin NF4L: > I was helping a friend with his remote setup.

They make a marginal contact with the SO-239 socket. Sometimes intermittent. The trouble it causes can be hard to identify. Junk connectors are a VERY common cause of problems. If the connector doesn't say Amphenol, it's almost certainly junk. An exception are the vintage connectors with MIL-spec numbers stamped into them.

Many thanks to Stephanie, Johanna, and Jashmin for accurately counting all of those tiny nuts, bolts and washers packed in what seemed like a hundred little envelopes and bags. Only 2 little bolts were missing, and were easily replaced from spares in the included extra parts bag. (thanks for including that Wayne) All seem to be well with the newborn after a minor visit to the ICU when one of the TMP cables didn't want to seat correctly in the J92 connector of the KRX3. A note to the folks that will be assembling/adding the KRX3 in the future, that J92 is mounted at a slight angle from the pcb, and it is prudent to support the back edge of the TMP socket while inserting the TMP cable connection. In my case, the connector started to pull up from the pcb so a small resolder operation of the ground connection was in order. All is well and the newborn K3 has exited the recovery room and has entered the world. How appropriate it was that my first contact with the new rig was with another K3 owner.

P3 Message-ID: Hi All, There has been a fair amount of discussion here about which accessory for the K3 trumps the other --a P3 or a 2nd RX. I don't have an answer, but I do have an opinion. I have the full K-Line here, but due to neighborhood restrictions, my antennas are modest. I use an R8 and a vertical dipole (Sigma 40XK) set up for 40 meters. That gives me decent coverage from 40 meters up, but nothing really fancy--and not a sure fire pile up buster! I'm certainly no threat to the "honor roll!" Hi. I think I have been a bit cavalier about relying too much on the P3 to spot DX listening frequencies with just the P3. I love the P3, but I can't say I have been particularly accurate by using it. I do turn on the 2nd RX fairly often, but more often than not, I get lazy about doing just that. The recent K1N Dxpedition was sort of a wake-up call for me about using the 2nd RX more. I'd use the P3, and think I had ID'd the listening freq., but it just wasn't producing any results. Their split was very wide, and besides that, stations were calling and calling, even though they weren't the station K1N had acknowledged. That' nothing new, but it was particularly bad on this operation. I was getting a lot of "false" readings just using the P3. For days I had "zero" success. Eventually I went to the 2nd RX, and the results improved dramatically. I got 5 band slots in fairly short order by doing so. There just doesn't seem to be a really good substitute for knowing exactly which freq. the DX station is listening on at the time. It doesn't guarantee success, but it sure gives you a leg up! I think, in my case at least, the 2nd RX may be the more advantageous for this kind of thing. Stations with more power, and bigger antennas, have a definite advantage. They can be picked out of the pile much more readily than I can. Some of the big guns have signals so strong they are like magnets! I think anyone in my shoes, who is trying to nab a good DX contact here or there, is apt to find the 2nd RX to be a great accessory, and more productive than the P3 for that particular purpose. Chances are I'm not using the P3 to it's best advantage, but I am trying to get better at it. I'm sure there are "tricks" I'm not aware of. Since the K1N DXpedition, there have been 4 or 5 other situations where the 2nd RX got me a contact in fairly short order--a couple of them just this weekend. Anyway, I'm getting more and more convinced that the 2nd RX was a good move on my part. The P3 was too, but it is more useful to me for other reasons. If I had it to do all over, and could only get one accessory, or only one at a time, I would start with the 2nd RX. By the way, on the KX3, the "dual watch" feature is priceless, and very effectively emulates a 2nd RX! K1N probably stretched the limits of that feature (15 khz), but generally that is more than adequate. The KX3 is just a super slick radio, and with the PX3 you have a dynamite combo!

My CONFIG:DUAL PB toggles between "nor" and "APF." The APF takes a little practice. Except when I'm NCS of our traffic net, I run about 250 Hz DSP BW. I have found that the APF gets very hard to tune with anything less than that and 300 Hz is even better. APF performance also seems to be somewhat connected to AGC settings.

P3 In-Reply-To: References: Message-ID: <550510C1.7050904@w0mu.com> A very difficult choice indeed. The P3 display can be studied to understand how a DX operator is working the pile. You can tell if he is working up or down the split or where in split in the case of large splits of late or if he is shotgunning it. I use both constantly. The 2nd receiver can be set up with just a couple of filters and you are good to go. The 2nd receiver is great to listen on a 2nd band if you have a 2nd antenna to use.

Yes, it is very good once you get the hang of it. I move the peak just a tad off of the center of the passband. It really seems to make a difference ... might be a result of my very compromised hearing, don't know.. It > is not something you will need to use all the time. There have been several posts over the time that APF appeared from people who use it essentially all the time. I use it a lot on weak signals at the noise, but not nearly "all the time." Any CW signal that's above my noise just stands out on the K3. APF also seems to help with multiple very weak signals in the passband. My guess is that when they're all at the noise, it's hard [at least for me] to actually associate a tone frequency to each, and they sort of just merge together. APF will usually yank the one I want out of the muddle. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From ron at midwin.com Sun Mar 15 01:21:44 2015 From: ron at midwin.com (Ron Midwin) Date: Sat, 14 Mar 2015 22:21:44 -0700 Subject: [Elecraft] S/N 1997 purchase date Message-ID: Found the receipt.

As taught me by my mentor K0AZ it is knowing "when" and "what" tool to use at the proper time to make a contact is what counts. Too bad there isn't a tool to do that also 8>) I know that I'm not using all the features that my K-Lines have but I'm still learning every day for all these years, then as soon as I get close new firmware and the learning and features start over.

You won't >need split and the dx is probably not going to move. > If "DX" holds any of its original meaning of "DX = Distant, DX = Difficult", then listening to the DX station on VFOB is a very bad idea. Although the K3's two receivers are identical in lab performance, they are not identical in terms of accessibility and ease of use. Apart from the VFOB knob itself, other subRX controls can only be accessed by first pressing the BSET button. Why is this important? Because you need to copy *every detail* that the DX stations sends! No matter how difficult it may be (and today we have to include a high probability of deliberate jamming) you need to copy the DX station's every instruction about where and when to call - and when he comes back to you, you need to hear that he copied your callsign correctly. That is why you should always listen to the DX station on your best receiver. The one that has all of its controls right there to hand. The MAIN receiver. If you listen to the DX station on the subRX, many of the important controls like SHIFT, WIDTH and APF can only be accessed by pressing the BSET button first - and while you're messing with that, Murphy will ensure that you miss teh DX station sending something important. But tuning the pileup is completely different. To plan your next call, you need to tune quickly to find the frequency where the station currently being worked is sending "5NN" or "fi-ni" - and that is all. No other details are important, and because pileups are so fast-moving and volatile, you won't even have time for any other controls. So why waste the main RX on listening the pileup? It really does seem perverse... and you probably know what I'm going to say next ;-) The only reason why anyone might want to adopt such a poor, counterproductive strategy is to avoid being caught out by the K3's dysfunctional SPLIT control. 73 from Ian GM3SEK From kk9wradio at gmail.com Sun Mar 15 09:38:32 2015 From: kk9wradio at gmail.com (kk9wradio) Date: Sun, 15 Mar 2015 06:38:32 -0700 (MST) Subject: [Elecraft] Kline for Sale Complete Message-ID: <1426426712162-7600280.post@n2.nabble.com> Complete K line system including K3 100 ,P3 with vga,amplifier, tuner, external display for p3.Rig is 3 months old, tuner is brand new.

P3 In-Reply-To: References: Message-ID: <60133.71.74.118.201.1426427213.squirrel@mail.expedient.net> What helps me a lot in cw pileup situations, is to set the filter width of the 2nd rx to as wide as it will go (2.8 KHz in my case), and tighten up the filter on the main receiver listening to the DX station. The wide filter on the pileup makes it much easier to quickly find the station currently being worked. I use both the P3 and KRX3 and wouldn't want to be without either, but considering the sadly frequent lack of good operating practice these days, you'll have the greatest chance of identifying the station being worked by using the 2nd rx. 73, Dale WA8SRA > Hi All, > > There has been a fair amount of discussion here about which accessory for > the K3 trumps the other --a P3 or a 2nd RX.

P3 In-Reply-To: References: Message-ID: <55058FC8.1010805@subich.com> A good analysis ... the P3 compliments the KRX3 and vice versa. Like Dave I have very modest antennas - an N6BT Q51 dipole at 6 meters for 20-10, an R5 or R7, and a 160/80/40 trapped inverted V at 12 meters. In many cases the P3 allows me to see quickly where the DX is listening, offset just slightly and get in quickly (if my signal is strong enough). However, with the bigger piles and the terrible operating behavior that has become the norm in the last 10 years or so the P3 doesn't do the job on its own. Just last night E30FB was on 40 CW calling for North America UP 3. Sure enough there were callers UP 3 on the P3 and the timing was right. After a few fruitless calls, I turned up the KRX3 and - sure enough - all the callers up 3 were simply calling whenever E30FB stopped transmitting. Looking at the P3 again - and using the KRX3 - E30FB was actually listening up 4.5. I called just above the last caller in a bit of a clearing and he was in the log. The same was true with K1N - although that one was almost a local. I think a lot of the "out of turn calling" is due to those who can not copy CW and are using decoders (whether that be in software or in the rig). Since the decoders are not 100% - particularly with QRM present - those lids simply push the memory/macro button to send their call every time the DX stops transmitting in hopes he will repeat himself *if* they were the one he was calling. Pile-up behavior on CW has become worse than what it was on SSB 40 years ago and phone is now so bad I won't even go there unless I need it for an ATNO (only 5) or band credit. 73, ...

It does exactly what it is designed to do - move transmit to the current setting of VFO B. If you want Quick Split, create a macro. Would it have been better if the K3 used a 16 button control pad vs. the 12 button pad? Sure. That would have allowed four buttons for VFO control/selection: A/B, REV, A->B (B->A on hold), Split (Quick Split on hold). It would also have provided three buttons to directly select mode - SSB, CW, DATA with "reverse" or DATA MD on hold - or be used for six additional macros. However, instead of the extra buttons we have a K3 that is 16 mm narrower than it would have been. 73, ...

Diagnosis was tough and I don't think anyone ever figured out what happened; after a good number of helpful but fruitless emails from Aptos I removed my sub and shipped it off to Elecraft for further troubleshooting. They found absolutely nothing wrong with it and sent it right back to me. I reinstalled it carefully as when I built it but still no joy. I double checked all the connections, filter configuration, etc. and everything was in place correctly. Just about when I was about ready to pull my last strands of greying hair out---I went through a whole new TX gain calibration (IIRC---it might have been another function but I'm 95% sure it was that). Voila! My sub sprang back to life as if nothing had ever happened! My only somewhat educated guess is that some stray RF from my full-bore QRO operation running split in hopes of snagging a DXpedition knocked the TX gain calibration out of whack (or something like that---others more technically inclined may well chime in with differing opinions) and thus my sub went almost deaf like yours (same symptoms exactly). So get out your K3USB cable and try another TX gain calibration; it will probably cure what ails your K3's sub (fingers crossed). 73 and GL, Jeff, NH7RO/AE (just passed my Extra exam yesterday afternoon; yippee!) http://www.louisferreira.org/Jeff_Cathrow.html From cathrowinternational at hotmail.com Sun Mar 15 12:03:35 2015 From: cathrowinternational at hotmail.com (Jeff Cathrow) Date: Sun, 15 Mar 2015 11:03:35 -0500 Subject: [Elecraft] sub rcvr problem Message-ID: I suppose I should have read the entire digest before replying; glad that Joe solved his deaf sub rcvr problem soon after he posted it here.

The weather has returned to normal here with steady, heavy rainfall, wind and cool temperatures. The daffodils got fooled into blooming early but now they are paying the price. Normally they don't even start until April. The sun has been active and caused a few communication blackouts this week. Hopefully the added ions will improve propagation for all of us.

Yes, I could use RIT and track each of you down but I am doing three things at once during each contact. My hands are busy with pencil, paddles, and two sheets of paper which makes tracking you down more difficult. I cannot change net frequency to follow you because I normally have to find an open frequency near where I have announced them.

So, when switching down to those bands I have to remember to toggle RX ANT off, then back on going back to 10 or 15 (where the PR6-10 works very well.) I am not sure of this, but I think the preamp can be set on a per-band basis using the cabling and removing the jumper, but not on a per-band basis by using the front panel RX ANT switch.

In-Reply-To: References: Message-ID: <24EAB20A-2CC7-4CC6-AFC9-717B6C4B0873@me.com> The K3 makes the determination. With RADIO set to K3, the BAND buttons simply send a command to the K3 that says which button was pressed. The K3 then does something. In the case of the AUX button, the K3?s decision is based on what features are installed. If a 2 meter module is installed, the K3 goes to 2 meters. Otherwise it will go to 10 meters. In all cases what the KPA does is determined by the state of the K3?s BAND outputs. Then there is the other answer - it has provided many, many questions about its use. ;-) - Jack Brindle, W6FB > On Mar 15, 2015, at 11:27 AM, Jim Miller wrote: > > What purpose does the front panel AUX button serve on the KPA500?

The KX3 has four internal options ? charger/clock, ATU, roofing filters, and 2m module. The K3 has far more than that. Also, the K3 is commonly used in complex base stations, with multiple antennas, external power amplifiers, and so on. So, more discussion about the K3 is normal. At this point, I think Elecraft has sold about the same number of K3?s and KX3?s.

New firmware for the KX3 will increase the mass of KX3 postings. New firmware for the K3 will likewise increase the mass of K3 postings. In the last month, they have announced a new super-low noise synthesizer for the K3, that's probably what you're seeing, it has been "all K3, all the time" recently. The K2 is a mature transceiver. Occasionally, someone will have a problem or a question and for a short period, the K2 may dominate the list. Likewise with the K1 ... we recently had a flurry of activity over the current and future unavailability of 4-band modules for it. Sometimes the list will be tilted to some particular ham usage or technique, such as diversity reception or EME or various digital modes, and not so much toward a specific product. It is very helpful if, when posting about a specific product, you put that product's ID in the subject line. Many people on the list filter their email into separate folders since they may not care about some products. It is also customary to end your post with name or nickname and call sign, if you have one.

So there's no need to manually switch it on and off all the time you change bands! My 6 m pre-amp is on all the time but the RX ANT state of the K3 is only put in on 6 m, not the other bands. This has nothing to do with the cabling. The cabling only takes care that the PR6(-10) internal relays are switched thru to allow an external RX antenna being used on other bands. So once again: if you do not use RX antennas (i.e. on the low bands) there's no need for the cabling from AUX to the PR6(-10) at all. Just switch it in on 6 m and be done. ;-) 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 15.03.2015 um 20:44 schrieb Dauer, Edward: > I do it without the Y cable as well; but there is one drawback to having > the preamp ?always on? - when it?s in the circuit on 40 and 80 it actually > degrades the K3?s performance (or at least mine does).

The easiest, most accurate way is to actually measure sensitivity using an XG-2 or XG-3 signal generator. You can check the S-meter on 80 and 160 compared to 20 meters and calculate the MDS on each band following the method in the signal generator manual. Have you calibrated the RF gain of the rig and checked the antenna settings (ANT 1/ANT 2 if you have the KAT3 or Main/RX if you have a KXV3 installed)? Both antenna settings are saved per band as is the preamp and attenuator. 73, ... Joe, W4TV On 2015-03-15 8:41 PM, Jan wrote: > I have a K3 that works fine on all bands except 75/80 and 160.

This is described on page 19 of the K3 manual. The KPA will see this as a switch to the 60m band, and thus will go to that band, displaying 5.3. Thus the behavior you guys describe is the correct one for both devices. You can actually fool the KPA into changing to a different band (although you?ll have a very difficult time getting it to go to 2 meters?) by setting the CONFIG:KIO3 to TRN, and then assigning the TRN settings in the menu. Again this is described on page 19 of the K3 user manual. Note, however, that if you do this, the K3 will not output the BAND signals for HF band operation, instead setting them to all zeros. This doesn?t make the KPA500 unusable, though, since it will automatically select the proper HF band when it does see HF energy on its input. Still, this might not provide the desired user interface for most ops. Since the K144XV (or any other transverter) does not output power through the standard K3 SO-239 connectors, there should be no problems with the KPA seeing RF on its input. Still, setting the KPA to STBY would be a good idea when you are using the 2 meter transverter. - Jack Brindle, W6FB Elecraft Engineering > > On Mar 15, 2015, at 6:21 PM, Harry Yingst via Elecraft wrote: > > > Mine does the same > Maybe a feature request to have the display in the KPA500 to show AUX? > > > > > > > > From: "kb2m at arrl.net" > To: 'Jim Miller' ; 'Elecraft Reflector' > Sent: Sunday, March 15, 2015 3:29 PM > Subject: Re: [Elecraft] [KPA500] Front panel AUX button? > > The AUX button on my KPA500 switched my K3 to 144.200 mHz, and itself to 5.3 > MHZ.

I used my TS-590s into a dummy load at it's minimum output of 5w on one side of the room and the K-1 into another dummy load on the other for signal generation and freq alignment (the 590 has a freq stabilizer installed). All the alignments went well and the K-1 fine tuned with full output power on both boards. I have (40/20) installed now and a (30/17). However, the noise levels with and without an antenna connected are identical. It's more hard of hearing than I am. I've read some previous posts regarding receiver sense and the possibility of a bad Q10. I was wondering if the recommendations would be the same in my case. Should I remove Q10 and see if that does the trick? I was hoping to take the rig on vacation with me.

The KX3 has four internal options ? charger/clock, ATU, roofing filters, and 2m module. The K3 has far more than that. Also, the K3 is commonly used in complex base stations, with multiple antennas, external power amplifiers, and so on. So, more discussion about the K3 is normal. At this point, I think Elecraft has sold about the same number of K3?s and KX3?s.

Is it a broadband hiss, some sort of squeal, etc? I no longer have my K1 but I seem to recall there can be some hiss in the audio. And how does it sound with an antenna connected? It could be that the noise you are hearing is drowned out by band noise and signals, and so is of no real consequence. 73, Phil W7OX On 3/16/15 2:37 AM, KH7AX wrote: > Just finished my new K-1 build and seem to be having way too much noise on > receive. > I used my TS-590s into a dummy load at it's minimum output of 5w on one side > of the room and the K-1 into another dummy load on the other for signal > generation and freq alignment (the 590 has a freq stabilizer installed). > All the alignments went well and the K-1 fine tuned with full output power > on both boards.

Yes it's broadband noise with another small higher pitched tone in the mix that does not include any of the assortment of other odds and ends you commonly hear when tuning up and down the band except for one very strong broadcast carrier right down close to 7.000 that's in our area. So if the signal is strong enough, as that carrier and also the 5 watt tone from my ts590 into the dummy load, it will get through. The noise level is the same whether or not the antenna is connected. Connecting the antenna, any antenna, bringsSo something is definitely wrong. -- View this message in context: http://elecraft.365791.n2.nabble.com/K-1-Poor-Receive-New-Build-tp7600322p7600333.html Sent from the Elecraft mailing list archive at Nabble.com.

In fact, I probably could have done just fine without ever having an 80 meter capability with the KX1. Primarily, I use the KX1 in portable QRP operations and in that scenario, 80 meters is harder to do because of the need for a better antenna then I typically put up. But, 30 and 20 meters are quite viable for QRP work with the KX1. I have used my 80 meter capability for only one kind of contact and that is a couple of times I would QNI into a CW net with QRP power. But, that was sort of just to use the newer 80 meter capability installed on my KX1. Today, I have done that using my KX3 so the KX1 80 meter capability will likely be unused from now on even though I have only had 80 meters on the KX1 since last year. If you have no great need for 80 meters such as joining some kind of scheduled net, I strongly suggest that you forget 80 meters for the KX1 especially when operating portable and definitely if you are operating from a hotel balcony. As for antennas, consider getting a Buddipole or Buddistick. I have the Buddistick and have used it successfully but never on 80 meters. 73, phil, K7PEH > On Mar 16, 2015, at 10:03 AM, J wrote: > > I'm considering replacing the 30M module in my KX-1 with a 30/80M module, > and had a few questions first: > > > > What chances of contacts with 4 watts on 80M. using a typical end-fed > antenna suspended from a tree or hotel balcony?

Mine would seat one side or the other but not both. I used a knife to par off a little notch in the cable housing to allow it to fit over the retaining nut. I even tried to line the nuts up so the sides were vertical but this didn't work. Hope you find the problem soon its a great system when all working together. 73 de Tony G6GLP On 16/03/2015 18:02, Rick Stanback wrote: > I just completed the build of my KAT500 and KPA500 and I had the > following issues. > > The KAT500: > the software was very flaky trying to connect to the KAT.

But it is generally not advisable to stay in AUTO mode during SSB transmissions as it still has a small probability of starting a full tune cycle during voice transmissions. AB2TC - Knut PS.

My first KX1, built in 2003 or 2004, had 20/30/40. My current one has all four bands. 80 m has never seemed a great QRP band for me, mainly due to the antenna issues. The KXAT1 *will* tune 80 m; there may be a mod you do to it while adding the 3080 module to make that feasible, not sure but the 3080 module instructions should tell you. Another plus of adding 3080 is in receiving 80 m and other non-ham frequencies, if you use the KX1 that way. Personally, if you have a KX1 with the original 30 meter module added I see no great benefit in adding the 3080 option in place of the 30 m module -- unless you have special interest in operating 80 meters. 73, Phil W7OX On 3/16/15 11:10 AM, Phil Hystad wrote: > I have a KX1 with 80/30 and I very rarely use it.

They take standard automotive fuses, and they're very robust. If you bought (or scrounged) a KXPA100 power supply cable, it would work well since it has APPs on one end, already crimped on. I've never had the problem you mentioned with the KXPA100's fuses. Anyway, just an idea. 73, matt W6NIA On Mon, 16 Mar 2015 16:12:05 -0400, you wrote: >My K3 is powered from a car battery as I am always /P.

I have an inline fuse holder for automotive fuses in the plus lead to each of the batteries. They have "OES" stamped into the plastic covers. If the fuse holders are warm to the touch, and there is not other source of heat nearby, then you have your smoking gun and that is where your problem lies. To trouble shoot this class of problems, measure voltage drops through the power supply wiring system. If there is a largish drop anywhere, find out why and correct it. I had to trouble shoot my battery setup with a dummy load and a brick on a straight key to discovered that the RigRunner part of the system wasn't able to carry full transmit load. Now there is a wire directly from the battery junction connector to the K3. Note that in an automotive installation, you need to fuse both the positive and negative leads. Fusing the positive lead is enough to cover most of the obvious failures -- radio develops dead short, a bare wire touches chassis etc. If the lead between the negative side of the battery and the chassis of the car (or a bolt on the engine) becomes loose, then when cranking the starter, the current from the starter may find a route through your antenna connection, radio and back to the battery. You want a fuse that will blow if this rare situation occurs. 73 Bill AE6JV On 3/16/15 at 1:12 PM, kk4oyj at gmail.com (John, 9H5G) wrote: >My K3 is powered from a car battery as I am always /P.

I have the Buddistick > and have used it successfully but never on 80 meters. I had a BP for quite awhile. It's a good antenna, but basically has two configurations despite the photos and diagrams in the literature: Horizontal and Vertical. Horizontal, it's an OCF loaded dipole and except for 12 and 10, is too low at any achievable height. I tried an extension mast made from copper water pipe, but with the stock tripod, it became top heavy and blew over in the lightest of winds. I had my best results as a center-ish loaded vertical ground plane. I ultimately got three of the 9' telescoping whips, used one for the radiator and two for two drooping radials. Didn't need loading on 10 and 12 meters. Unfortunately, on SOTA summits, verticals tend to radiate downslope. I tuned it with an MFJ-259. Setup and tuning took quite a while [~30-45 min] and band QSY took maybe 30 min. It was fairly heavy, about 17 lbs. I finally sold it and bought an Alexloop. It, and a very lightweight tripod weighs less than 3 lbs, it sets up in 5 min, and works amazingly well. It is insensitive to ground, I sit under it so I can reach up to the knob. Tuning is a little touchy on 40, better on 30, and fine on 20 and up. Tuned magnetic loops are resonant transformers. Bypass the ATU and tune the loop to 1:1. If you "get it close" and then run the ATU, you'll have a fairly good, non-radiating dummy load. Usual disclaimer, other than writing checks, I have no financial interest in Buddi-anything or or Alexloop. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From vk1zzgary at gmail.com Mon Mar 16 19:48:32 2015 From: vk1zzgary at gmail.com (Gary Gregory) Date: Tue, 17 Mar 2015 09:48:32 +1000 Subject: [Elecraft] K3 power supply fuses In-Reply-To: <550761E7.7040101@foothill.net> References: <71402902-8A29-433E-9F04-17C8F99ACAB5@gmail.com> <550761E7.7040101@foothill.net> Message-ID: Fred, As are lead acid batteries.

My first KX1, built in 2003 or 2004, had 20/30/40. My current one has all four bands. 80 m has never seemed a great QRP band for me, mainly due to the antenna issues. The KXAT1 *will* tune 80 m; there may be a mod you do to it while adding the 3080 module to make that feasible, not sure but the 3080 module instructions should tell you. Another plus of adding 3080 is in receiving 80 m and other non-ham frequencies, if you use the KX1 that way. Personally, if you have a KX1 with the original 30 meter module added I see no great benefit in adding the 3080 option in place of the 30 m module -- unless you have special interest in operating 80 meters. 73, Phil W7OX From kh7ax.mail at gmail.com Mon Mar 16 21:32:23 2015 From: kh7ax.mail at gmail.com (KH7AX) Date: Mon, 16 Mar 2015 18:32:23 -0700 (MST) Subject: [Elecraft] K-1 Poor Receive, New Build In-Reply-To: <1426498631154-7600322.post@n2.nabble.com> References: <1426498631154-7600322.post@n2.nabble.com> Message-ID: <1426555943430-7600374.post@n2.nabble.com> Not sure what I'm to do next.

DATA A mode is like SSB with the following exceptions: 1) TX EQ is disabled in DATA A mode 2) Audio compression is disabled in DATA A mode. 3) one can set the audio input to LINE IN for DATA A mode - no need to change it from MIC audio when using data modes. Either of those conditions may be present in SSB mode, and the first 2 will distort a data mode signal. So the answer is to use DATA A mode instead of SSB so you do not have to manually turn off those 2 conditions when running data modes in SSB mode. Unfortunately, some data mode software does not include recognition of the K3/KX3 DATA A mode and will force the rig to SSB mode. Be watchful of that condition and respond accordingly. The K3 offers a seamless solution to the use of both SSB and Data modes and is beneficial as long as you do not have to "fight" with the data mode software application to get that to happen. 73, Don W3FPR On 3/16/2015 8:43 PM, Sam Morgan wrote: > I have been running DATA A with my SignaLink USB for JT65 & JT9 using > WSJT-X.

The receiver muting is the easiest - is Q10 working is the question. If the gate of Q10 goes to 6 volts during transmit, but the audio is not muted (except for the sidetone), then Q10 may not be doing its job and deserves replacement. If it is a situation with the T/R switch, the problem is more complex. I can give you some points to measure DC voltages if Q10 does not cure your problem. You may have the skills to figure out the voltages that should be present in the T/R switch diodes for both RX and TX. If not, send a private email and I will try to help. 73, Don W3FPR On 3/13/2015 4:18 PM, bill m via Elecraft wrote: > My K1 SN1730 has unfortunately learned a new trick.This radio was my first Elecraft kit many years agoand has been a rock solid reliable radio until a few days ago.I started getting a little squeal through the speaker on transmit and it quickly went away and the radio started acting like it's own transmitter wasoverloading the AGC and shutting down the receiver for a couple of secondsor longer.

The amount of attenuation you hear is about the same as the isolation between the antenna selection in the K3 (40 to 50 dB). The antenna selection is on a per band basis. 73, Don W3FPR On 3/15/2015 8:41 PM, Jan wrote: > I have a K3 that works fine on all bands except 75/80 and 160.

The K1 will operate without Q10 installed, so that is your first troubleshooting tactic. However, without Q10, the receive audio will not mute when in transmit - just something to be aware of when evaluating the effects. If removing Q10 does not solve the RX problem, you will have to resort to Receive Signal Tracing in the back of the K1 manual. You will need a strong signal source and an RF probe to do that tracing. The Elecraft signal generators do not have sufficient output for that testing - I would recommend building the oscillator shown in the manual - the crystal should be within the tuning range of your K1. 73, Don W3FPR On 3/16/2015 5:37 AM, KH7AX wrote: > Just finished my new K-1 build and seem to be having way too much noise on > receive. > I used my TS-590s into a dummy load at it's minimum output of 5w on one side > of the room and the K-1 into another dummy load on the other for signal > generation and freq alignment (the 590 has a freq stabilizer installed). > All the alignments went well and the K-1 fine tuned with full output power > on both boards.

An end fed antenna suspended from a tree or a hotel balcony is not likely to do the job on 80 meters simply because it will have to be too long for practical purposes in those situations (135 feet). If you are happy with your 40, 30, 20 KX1 and do not have any pressing needs to add 80 meters, I would not change it. OTOH, if you are backpacking in the US Southwest areas and want to have a source of emergency communications (due to propagation conditions), 80 meters may be the only logical choice - just check out the antenna situation before embarking on your trip. 73, Don W3FPR On 3/16/2015 1:03 PM, J wrote: > I'm considering replacing the 30M module in my KX-1 with a 30/80M module, > and had a few questions first: > > > > What chances of contacts with 4 watts on 80M. using a typical end-fed > antenna suspended from a tree or hotel balcony?

The in-line 3AG fuseholders often do not have sufficient pressure contact with the ends of the fuse for a good connection. Poor connections to the fuse will cause the fuseholders to heat and also cause extra voltage drops in the power cable. 73, Don W3FPR On 3/16/2015 4:12 PM, John, 9H5G wrote: > My K3 is powered from a car battery as I am always /P.

If it were me I'd take a look at the inductors LD-LG (on page 4 of the schematic) to see if there is the possibility of one of them being shorted. I haven't had look at these but it's common to twist the terminating wires together - a likely spot for a short. I'd stick the CRO on the output of each of the 4 inductors (where the circuit shows "RX_I" and "RX_Q" and the opposite side of C1K and C1L) all the levels here should be pretty much identical. Of course you can only expect this over the range of +- 96kHz or so. 73's Peter VK4JD PS - love this little radio, it's an amazing bit of portable kit -----Original Message----- From: John [mailto:kx4o at hamradio.me] Sent: Tuesday, 17 March 2015 1:53 PM To: Peter Lambert; Elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 IQ Outputs - What to expect?

AFSK A and DATA A are both audio modes. AFSK A uses LSB and FC is set to MARK - 85 Hz (the center of the two RTTY Tones). DATA A is USB and FC is set to 1500 Hz (the center of the transmit audio passband [200 - 2800 Hz]). AFSK A also allows use of the AFSK transmit filter (a tight filter around the Mark/Space tones to eliminate hum/pops/etc.) and the use of the Dual Tone filter on receive. 73, ...

DATA A can be used for all audio-shift transmission modes, including AFSK and PSK-31. VFO A shows the transmit suppressed carrier frequency and USB is normal for DATA A. Compression is automatically set to 0 to reduce transmitted signal distortion. AFSK A is also an audio-shift transmission but is optimized for RTTY. VFO A displays the RTTY mark frequency and LSB is normal. The built-in text decoder and the dual-passband RTTY filter can be used. 73, Mike NF4L > On Mar 17, 2015, at 12:41, Fred Jensen wrote: > > Can you 'splain the difference between AFSK and DATA A?

I think it has what you need. 73 Mike KF6KXG ELECRAFT KX3 Application Note Determining I and Q signal output levels Revision A, February, 2013 Copyright ? 2013, Elecraft, Inc.; All Rights Reserved Background The KX3 provides a way to connect to popular Software Defined Radio (SDR) programs. Most of these programs utilize a PC-based soundcard to import the I and Q signals into these programs. This Application Note discusses the I and Q signals provided by the KX3 for this purpose. Determining the I and Q signal levels in the KX3 Equipment required: ? Dual channel Oscilloscope with at least 10mv per division sensitivity ? Signal Generator with -73dbm output. An XG3 or equivalent will work. ? 2.5 mm Stereo phone plug or other means to bring out the I and Q signals from the I/Q Jack Procedure: 1. Connect the oscilloscope vertical inputs to the tip and ring of the phone plug and plug into the IQ output jack 2. Set up signal generator to supply a S9 (-73 dBm ) signal to the KX3 antenna connector. 3. Tune the radio to the signal supplied by the signal generator. 4. In the KX3 menu go to " RX I/Q " Set it to "On" 5. With the Oscilloscope set to 500us per division and 10 mv you should see something similar to the picture below. Note that one trace is shifted in phase to the other by 90 degrees. Elecraft ? www.elecraft.com ? 831-763-4211 Guidelines for using a KX3 I and Q signals with an SDR ? Check configuration of your PC's soundcard for Recording devices and levels. We have found that many PCs default to Line level inputs rather than Mic level inputs. ? Confirm that the Mic input is set up for Stereo inputs. We see many PC's - laptops mostly - do not have a 2nd channel for the Microphone input. This will not work, of course, with the KX3/SDR setup as there are 2 complete channels required for I and Q signals to be amplified. ? Once set up for Mic input, ensure that all Input Level sliders are set to their mid point. Many drivers will have a +10/+20dB boost slider. Noise floor will rise with its use but the signal will appear in an SDR easier. We have seen that some soundcard drivers will also provide a handy bar graph of VU metering to allow you to see whether there's I/Q coming into the PC. ? Bring up whatever SDR software program and ensure that it has been configured to select the appropriate soundcard links for input and output. ? Monitor the levels of the I/Q with that program. Most of the SDR programs have some form of level indicator for input. Eliminating Ground Loops with PC soundcards ? Hum and Noise At times, we get reports of noise and hum on the I and Q signals. Typically, we find this is due to use with a PC with floating soundcard inputs which may create ground loops. In turn, this creates extra noise on the I and Q signals input into the soundcard. Additionally, noisy brick power supplies can raise the noise floor further. Generally, the use of isolation transformers will break the ground loops between a PC soundcard and the KX3's outputs. These are typically available from Radio Shack, PAC-Audio and Amazon.com, although some adapting of the connectors may be required for the 2.5mm connector on the KX3 I/Q port.

I think I have it figured out. I recently sold my SteppIR vertical which required me to use the PTT Key line to prevent the amp from keying while the SteppIR was moving. This piece was used to interrupt the PTT in the AUX cables (missing the 10 pin.) So when I removed the cables for the PTT key lines, I just forgot to take this little part off. Good, that 'splanins it and tells me I was not keying the amp for the last three and a half weeks. Maybe Elecraft should develop a flashing red light to warn a guy that he is not keying the amp when he thinks he is ..... just kidding! 73 ..mike AI6II -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-suddenly-low-output-only-30-watts-tp7600292p7600406.html Sent from the Elecraft mailing list archive at Nabble.com.

Of course I also figured it out at the same time. Interestingly one fellow suggested I 'read my manual', which of course I do daily (smile), but I already knew the 10 pin controlled the the PTT inhibit. I just didn't realize the gender changer had the 10 pin removed until I picked it up again and saw the writing on it for the first time. Getting old and don't always see things at first glance.

That is the correct audio level - set the power to the level desired and go. One thing about the K2 power level is that it is reset after a band change or a power level change. That is better than creating a power spike. It takes a couple of dits in CW or a few syllables in SSB mode. Because your data audio stream is not syllabic, it may take a bit longer for the K2 to adjust to the proper power level. There is no work-around that I know of other than doing a "throwaway" transmission into a dummy load after a band change or a power level change. 73, Don W3FPR On 3/17/2015 4:48 PM, Steve Kavanagh wrote: > I'm starting to play a bit with JT65 on HF (using WSJT-X) with my K2 and homebrew interface hardware.

It seems to happen less when I have plenty of audio drive - does it make sense that the K2 power control might get a bit confused by switching transients when there is only just enough audio to get the RF output up to the value set with the power knob?

Operator/User manuals tend not to answer that question, they are understandably focused on exactly how to operate the equipment. I'm very sure that, when I first set up RTTY, I went to AFSK A because I knew what audio frequency shift keying was and I didn't know what DATA A was. It all worked, so I never changed it or tried out the other choice. I guess if AFSK A is LSB and works with MMTTY in its default configuration, then DATA A is USB and I'd have to reverse the tones in MMTTY. I'll leave it as I've been using it, it works so it obviously doesn't need fixing. I was just curious. I have my "pitch" set at 915 Hz, I can't hear 2,125 Hz.

Hi Fred, AFSK A and FSK are for RTTY. They are set up to put the other guy's signal in the passband of the RX IF, so we can use filters on it. It's for "single-frequency", like we would do with MMTTY. You want to work a different station, you tune the big knob. DATA A is for digital software that has a multi-decoder function -- it decodes all the signals it can find in the 2.7 kHz bandwidth of an SSB rig. If we listen to the speaker (or headphones), we hear a bunch of signals, not only one. The usual computer display is spectrum and waterfall, similar to the P3. We choose which one we want to work by clicking on the decode string. I use AFSK for RTTY and DATA A for everything else. For non-contest RTTY operation, I use WinWarbler, which is a sort of package for MMTTY, and allows a 2Tone window. 73, Jim K9YC From fptownsend at earthlink.net Tue Mar 17 20:03:35 2015 From: fptownsend at earthlink.net (Fred Townsend) Date: Tue, 17 Mar 2015 17:03:35 -0700 Subject: [Elecraft] HP 8921 problems In-Reply-To: References: Message-ID: <002001d0610e$fb1a8500$f14f8f00$@earthlink.net> Niel: I think electrolytics are a good guess. Also selenium rectifiers but I don't think that model uses them. The problem is aluminum electrolytics are not made anymore. You can substitute polymer electrolytics but while they are electrically interchangeable they are not form-fit interchangeable. Sometimes it takes some mechanical rework to fit them in. I have seen aluminum electrolytics on the surplus market but they will be old and unreliable. Your best bet is the polymers. You'll find them at Digikey, Allied, and the like. 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Niel Skousen Sent: Tuesday, March 17, 2015 2:00 PM To: Elecraft Reflector; QRP-L Mailing List Subject: [Elecraft] HP 8921 problems Good Afternoon All, I have an HP 8921 Service monitor, and when I powered it up today, it worked for about 5 min... then the power supply started to sag, the display crashed, and I powered down.

Some waterfall display oriented data mode software will do fine sending and decoding RTTY as well as other data modes. MMTTY (which is the main choice for RTTY operation) does not do a waterfall and you tune to the signal desired with the VFO. A similar situation is true for PSK D and FSK D - you tune to the desired station with the VFO rather than clicking on a waterfall display. For those who are not clear about the data sub-mode designations try this: DATA A = Data mode (Audio) = waterfall display oriented (point and click) AFSK A = AFSK mode (Audio) = Tune in a single station with the VFO PSK D = PSK mode (Digital) = send CW with paddles (or ASCII in KY command), receive on K2 display or K3 Utility terminal FSK D = FSK mode (Digital) = send CW with paddles (or ASCII in KY command or 'wiggling the FSK IN pin on the ACC jack), receive on K2 display or K3 Utility terminal Hopefully that helps with understanding of what the "A" and "D" suffixes mean. In summary, if you are using an application that has a waterfall display, use DATA A and point and click on the waterfall to select the station. How you use the data sub-modes depends on which software application you are using as well as the physical connections to the K3. 73, Don W3FPR On 3/17/2015 6:48 PM, Fred Jensen wrote: > Hmmm ... this may be the first time Fred Cady's book has failed me.

If you have an early K3, there may be inductors in the ground path (and they may still be shown in the schematics). Those inductors were removed in later K3s and the Line-in and Line-out shells are now indeed grounded. Those inductors in the ground path can (and should) be removed (should you have an earlier K3 with them still in circuit). See "Improving the Immunity of Rear Panel RS-232 and Audio Connectors to RF" at http://www.elecraft.com/K3/mods/ELECRAFT_Application_Note_Improving_the_Immunity_of_the_Rear-Panel_KIO3_RS232_and_Audio_Connectors_to_RF.pdf. If you are dealing with a later K3 and have such problems with the SignaLink interface, follow Mike's instructions to combine the separate grounds into one bonded ground. 73, Don W3FPR On 3/18/2015 6:36 PM, mpupeza at sympatico.ca wrote: > ALERT!If you use an ethernet box to switch between a SignalinkUSB box and another modem, you may be in for some surprises.The Tigertronics SignalinkUSB cable SLCABK3 brings out 6 of the wires to the RJ45 connector.

Buy a copy of whatever flavor of Windows you prefer and use Boot Camp to boot your Mac directly into Windows. It'll run Windows natively, and better than most Windows machines. I know that finding ham stuff for the Mac can be frustrating, but it can be done. I only run Macs in my shack exclusively, and the only reason I ever run Windows on them is when I have to program my HTs. My logging programs, etc. are all OSX programs and free ones at that. I don't venture too far into the esoteric operating-wise, though... Good luck! 73, Scott, N9AA On 3/18/15 7:59 PM, Dauer, Edward wrote: > OK; I give up.

Steve, On the K2 with any data mode, run the audio up until you see one ALC bar, and then back it down until it just barely goes out. That is the correct audio level - set the power to the level desired and go. One thing about the K2 power level is that it is reset after a band change or a power level change.? That is better than creating a power spike.? It takes a couple of dits in CW or a few syllables in SSB mode.? Because your data audio stream is not syllabic, it may take a bit longer for the K2 to adjust to the proper power level. There is no work-around that I know of other than doing a "throwaway" transmission into a dummy load after a band change or a power level change. 73, Don W3FPR On 3/17/2015 4:48 PM, Steve Kavanagh wrote: > I'm starting to play a bit with JT65 on HF (using WSJT-X) with my K2 and homebrew interface hardware.? The frequency response of the K2 seems reasonably flat, but occasionally I see power dropouts when the tones change.? This is despite always hitting the requested power at any audio frequency using the "tune" button in WSJT-X. It seems to happen less when I have plenty of audio drive - does it make sense that the K2 power control might get a bit confused by switching transients when there is only just enough audio to get the RF output up to the value set with the power knob? For those who are using WSJT modes on the K2 successfully, what ALC readings do you usually run at ? I'm hoping eventually to get the K2 going with transverters for VHF meteor scatter on FSK441 - is the stock OP1 filter wide/flat enough to work well for this mode??

Recently I've seen the advantage of Blu-Ray quality video compared to conventional DVD quality video with my HD TV. For those like me, the difference is more than a little and the definition is incredibly life-like and very desirable. I looked at my TV and monitor, both have conventional video, Displayport and HDMI inputs. I'd like to be able to connect the P3 to the monitor with this quality display. HDMI now is at V 2.0 and Displayport is V 1.4A. The earlier Displayport versions offer essentially the same definition as the newest HDMI, with the newer Displayport doubling the new HDMI standard. Inexpensive cables to convert from Displayport to HDMI & vice versa are readily available. Most PCs and by far most of the laptops have Displayport or HDMI video outputs nowadays. My 5 year old HP laptop has Displayport & VGA not HDMI. The Displayport is the new standard, HDMI is legacy and will also persist for the foreseeable future. I'd like to see Displayport or HDMI incorporated into the P3.

Plenty of power for anything in the ham shack. They also come in i3, i5 and i7 configurations if you need more power. The NUCs are available through Amazon and most other computer distributors. You can also look up the specs and the various models on intel's website. 73, Doug -- K0DXV On 3/18/15 5:59 PM, Dauer, Edward wrote: > OK; I give up.

Some of the off-list messages cautioned against using a Mac as a platform for Windows, while others (below) have had more favorable experience. The problem for me, however, is the footprint of my MacAir on the desk - which is one of the things I would like to be rid of. Among the suggestions made both off-line and on is the NUC from Intel. Interestingly, one of the housings made for the NUC is called the K3. Who could resist a marriage like that?

I wonder though what software you feel is missing for your Mac? For logging I like RUMlog or the new RUMlogNG. They integrate with my K3 nicely, and in the case of RUMlogNG, the P3 control screen is something I miss when I play with other loggers. For Digital there is FLDIGI or cocoaModem. While cocoaModem is no longer supported by Kok Chen it is still very functional and has the unique advantage of being able to watch two RTTY screens at the same time if you have the Sub. For contesting I use RUMped or Skookumlogger. BTW, I am puzzled about your comment about lacking drivers for your Dell display for the Mac. I have never needed any drivers for any monitor I have used on my Macs. Currently I have an Asus connected to my mini using DVI and an HP using HDMI. 73, Rick K6LE On Wed, Mar 18, 2015 at 4:59 PM Dauer, Edward wrote: > OK; I give up.

Not everyone has the spare funds, some of the costs for "signed" programs and code, can be quite expensive, for a ham on a pension. I do run Win64 here in the office, but there are many XP and earlier app's that do not play well on it, if at all due to direct IO needs. The XP emulator is not up to that sort of work, even when it can be kicked into life. NO Win16 apps will run in any way shape or form on Win64, period! (Some don't play well on Win7 32 bit either, but they can be coaxed and cajoled.) Running XP in a real VM (V'box) is OK, but again, you need a licenced copy to install. I do this sort of thing for a living, not just for my own needs, so I do know what can/can't be done. 73. Dave G0WBX. > Hi, > That is definitely NOT the case.

But 32 bit is essentially obsolete. Most software that is still currently maintained and most hardware for which current drivers are available will run without issues on 64 bit Windows. As a Windows 10 Beta Tester I can also say that I'm experiencing Windows Fatigue. I'm tired of the constant churn in the U/I. XP, Vista, Windows 7, Windows 8, and Windows 10 all rearrange things just enough to be annoying and confusing. I'm now very much a Mac fan, although I find the prices of Apple products outrageous. While it is a highly usable U/I that is very consistent from release to release, the hardware remains a real issue. A decent Mac Mini is about $700. An equivalent NUC PC is half that. So, like Dave, I see linux as the future. My favorite is Linux Mint with the Cinnamon U/I. Perhaps the most popular linux distro on the planet. When I login to my linux box, it is always a pleasure to see a simple, non-intrusive, intuitive user interface, completely lacking in the heavy, complex and confusing baggage that Windows carries around. Mint Cinnamon and most other linux variations will take the average user a couple hours to get their arms around. Once you do however, you'll find yourself getting addicted to its beautiful looks and simple organization. Must linux distros will run circles around Windows on pretty basic hardware. It's also, surprisingly, extremely reliable, having been under non-stop development for over 20 years. 73, Doug -- K0DXV On 3/19/15 10:02 AM, Dave B wrote: >> Subject: [Elecraft] Windows Computer for K-line station >> Message-ID: >> Content-Type: text/plain; charset="iso-8859-1" >> >> OK; I give up.

Lots of QSB, and I'm hearing a lot more noise than usual. Of late, I've had problems getting 100% copy on some stations because the QSB, even when fast and not too deep, has clipped characters I try to copy (on CW) making it easy to miss something here and there. I've been checking my AGC to make sure it was fast rather than slow, but that didn't always solve the problem satisfactorily. Now, I do often just turn the AGC off, but that's usually to avoid the pumping that the AGC can cause. I've always been an advocate of turning the AGC off at times, but I noticed something else recently. Probably I've noticed it before and just didn't think about it. The recent combination of QSB and higher noise were BOTH much improved by just turning the AGC off. The noise went down considerably!!! That improved everything, and copy became 100%, or close to it! I don't know why I didn't think to do this sooner! Anyway, I am guessing that the AGC is enhancing the noise, and it has nothing to do with the K3 itself as to any oddity.

Hi. Time > for me to read, or re-read, how to properly take advantage of AGC! First thing to to do is get out your XG-2 or XG-3 and run the RF gain calibration on the K3. If the gain cal is off, the AGC may activate well before the signal has a chance to quiet the noise. Sherwood had that experience when he tested a K3 with the new synthesizers that had not had the RF Gain Calibration performed before it left the Elecraft factory. 73, ...

When testing AGC setting, listen not for the signals themselves, but to the pauses in the signals. For more guidance on choosing the right AGC settings for your condition, check out the "Noisy K3" article on my website www.w3fpr.com. 73, Don W3FPR On 3/19/2015 12:59 PM, dyarnes wrote: > The recent combination of QSB and higher noise were BOTH much improved > by just turning the AGC off.

I usually keep my AGC THR set to about 18. However, the higher the threshold, the closer the dynamic range approaches that of no AGC, but without the danger of overload or hitting the limiter that will protect your hearing. If that isn't to your liking try dropping it down to the mid to lower teens. Also -- don't overlook something as easy as simply reducing your RF Gain control. As you first begin to reduce it, the results are virtually identical to what you'll get by raising the ACG THR level -- and it's right there on the front panel. You may find that's all you need. 73, Dale WA8SRA > Hi again, > > I got several very nice responses to my question already, and it seems I > need to do some adjusting.

First, set the SLP to 15. That will give the most AGC action -- all signal strengths will sound about the same. You might want to do this if you are listening to a round table of differing strength signals. I keep my SLP = 0, to allow me to distinguish between strong and weak signal in a contest situation. Next, choose a noisy band or the band that you want to set the AGC THR. It very well could be different on different noisy bands. Now, while listening to the noise, decrease the THR until you hear a decrease in noise. You could also use the AFV and dBV measurements but that is a bit trickier. If it were me, I'd set the THR a little higher than where it starts to be activated by the noise. Actually, I like to run THR pretty high because I like to operate the receiver in a linear region to distinguish different strength signals. Sometimes, though, I run the THR down a bit when there are a bunch of weak signals, like EUs calling, in addition to a bunch of strong US stations. Then having the AGC clip the stronger signals lets me run the AF or RF gain up to be able to hear the weaker EUs without blasting my ears with the stronger stations. The bottom line is that there is tremendous flexibility in setting up the AGC and one size doesn't fit all.

The header is on the back of the Front Panel Board. See the KSB2 manual for the mic header connections for several popular microphones. If you want to change microphones frequently, you might want to look into the IMA sold by the UnPCBs guys - http://www.unpcbs.com/adaptor/ Another alternative is to wire the microphone configuration header for the Elecraft pinout and re-wire the microphone plug on the microphone you intend to use with the K2. Of course, that will dedicate that microphone to use with Elecraft gear. Remember that microphones with electret elements (computer type mics, Elecraft mics, and Icom mics) will need bias applied to the AF mic pin. Dynamic mics (most others) should not have bias applied or they will "sound funny". If you need information about various microphones and their wiring, take a look at http://homepage.ntlworld.com/rg4wpw/date.html - G4WPW has compiled an impressive list of microphone information. 73, Don W3FPR On 3/19/2015 3:56 PM, Aaron Scott wrote: > Are the MH2 Hand Microphone and the Proset-K2 the only microphones that you > can get for the K2? > From crcooklb at gmail.com Thu Mar 19 18:21:17 2015 From: crcooklb at gmail.com (Randy Cook) Date: Thu, 19 Mar 2015 15:21:17 -0700 Subject: [Elecraft] FS: P3 /SOLD In-Reply-To: <907412F6-1992-4B71-97DB-6FE41F8A2B4A@gmail.com> References: <907412F6-1992-4B71-97DB-6FE41F8A2B4A@gmail.com> Message-ID: <98DCF3A4-07AA-450C-B7EE-C72DA13A8E2D@gmail.com> Pending receipt of funds. 73 Randy- K6CRC k6crcus at gmail.com From nq5t at tx.rr.com Thu Mar 19 22:24:20 2015 From: nq5t at tx.rr.com (GRANT YOUNGMAN) Date: Thu, 19 Mar 2015 21:24:20 -0500 Subject: [Elecraft] AM Transmit Bandwidth Message-ID: If the FM filter is assigned to AM transmit, is there any improvement in transmit audio bandwidth beyond 3 KHz,or does it remain DSP limited to this relatively restricted range?

I would like to use the open-collector interface on the AT1000 (which is pulled low during tuning) to pull the KPA500 Inhibit (Aux Pin 11) line low so that I am not running high power into the tuner during tuning. (Note: I will also at the same time use the open-collector output to pull the correct line of the FTDX3000 low to enter the low power CW key-down mode.) Any "gotchas" with this scheme? The KPA500 will be keyed up via Aux pin 10 at the same time it will be inhibited via Aux pin 11. Is there a delay I have to be worried about? Is there an order of the pull-downs that matters? Am I going to get a few msec bump of high power? I realize that one normally interrupts the amp via the key line, but it seems a little more straightforward in my particular case to do it via the inhibit line.

I think you're doing it the hard way, Jim. The KPA500 senses RF very quickly, so you don't need to feed it band data. A dit or a tap on the mic is enough. I would do only whatever switching you need to protect the tuner. If the tuner has a "loop-through" interrupt relay for the amp key line, I would use that. If it doesn't, go ahead and use the inhibit on the KPA. Also, the KPA500 drives to full power with about 30W, so that should be your usual power out setting for the FT3000, except on 30M, where 12W is about right. Most auto tuners are happy with those drive levels. 73, Jim K9YC From jackbrindle at me.com Fri Mar 20 18:58:07 2015 From: jackbrindle at me.com (Jack Brindle) Date: Fri, 20 Mar 2015 15:58:07 -0700 Subject: [Elecraft] KPA500 Inhibit Line In-Reply-To: <277409093.14033665.1426857267854.JavaMail.zimbra@comcast.net> References: <277409093.14033665.1426857267854.JavaMail.zimbra@comcast.net> Message-ID: This actually should work. The #INHIBIT signal will disable transmission rather quickly, at least as fast as the key line. The catch is that most tuners don?t detect high SWR and output their tune signal all that fast. In fact most use a relay, adding 7-10 mSec of time to the overall time. You will probably end up with something like 15 to 20 mSec of delay between key down and disabling of amplification. Cutting that down as much as possible is generally a good thing. Now having said all this, this is exactly the problem that #INHIBIT is meant to solve. #INHIBIT is the fastest way to disable amplification, causing the proper TR switching sequence along the way, exactly the same way the negating the KEY line does. The general discussion above of reducing the ATU?s HI SWR / fault detection is important in that you want to reduce the time the amplifier is subject to the bad conditions. We took great lengths to reduce this time using the KEY line using the KAT500, unfortunately most ATU manufacturers don?t take quite as much care in this area. So, the answer to your question is yes, you will get sever mSec of high power, something like 10 to 20 mSec. Let us know how your experiments come out. - Jack Brindle, W6FB Elecraft Engineering > On Mar 20, 2015, at 6:14 AM, j-meister at comcast.net wrote: > > Setup is Yaesu FTDX3000 xcvr --> Elecraft KPA500 amp --> LDG AT1000ProII tuner.

However, I'm certainly not the expert here. For US hams, 47CFR97.307 begins: "(a) No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice" which would sort of preclude SSB much wider than what the K3 normally does. However, I am neither a Commissioner nor a lawyer. There were a few RCA Ampliphase 1KW AM transmitters made and they sounded pretty good in a 10 Kc channel. One or two might still be around and available. :-) Actually, I don't think RCA invented those. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/19/2015 7:24 PM, GRANT YOUNGMAN wrote: > If the FM filter is assigned to AM transmit, is there any improvement > in transmit audio bandwidth beyond 3 KHz,or does it remain DSP > limited to this relatively restricted range? > > Grant NQ5T From w3fpr at embarqmail.com Fri Mar 20 20:02:12 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Fri, 20 Mar 2015 20:02:12 -0400 Subject: [Elecraft] AM Transmit Bandwidth In-Reply-To: References: Message-ID: <550CB504.9030400@embarqmail.com> Grant, The AM audio bandwidth is limited by the DSP - both for transmit and receive.

It?s learning rate is too rapid, and that causes it to lock on and off of rapidly varying voice peaks during SSB phone reception. The effect sounds much like someone overdriving their mic input at the transmitter. Last night I was listening in headphone diversity mode, with my K3 on the left and an IC-7700 on the right, to some SSB comms. The left ear (K3) sounded crackly and distorting, like the op was overdriving his transmitter, but the right ear (IC-7700) sounded just fine. I removed diversity by listening only to one receiver or the other. The IC-7700 continued to sound okay, but the K3 was gritty and abrasive, and I could not tolerate listening for any long duration. So I started tracking things down?. I normally listen to the SSB subbands with the auto notch enabled to avoid all the tuner uppers, and with the NB enabled at a very low setting just to get rid of incidental impulses. After disabling the NB no change occurred. I then examined both the K3 and the IC-7700 audio output on an audio spectrum analyzer. There were no obvious indications of IMD in either of them. So perhaps I need to feed 2 tones? I did so, and still no IMD. I tried lowering the Line Output setting, fearing that I might have it too high and I was inducing harmonic distortion, but the spectrum analyzer showed nothing down to -60 dBc. Just by chance, I removed the AutoNotch while listening to some more SSB phone, and immediately noticed that the speaker?s voice quality dramatically improved. Aha! The AutoNotch is too quickly adapting to varying voice peaks, and the sudden disappearance / appearance of nearby treble peaks in the voice was causing a crackling sound in my headphone. I notice that on heterodyne tones the K3 almost instantly removes them, while the IC-7700 takes a fraction of a second longer, perhaps 100-200 ms.

This mirror was tested at better than 1/8 wave accuracy, (P-P wavefront) A tested value of .972 for Sterehl rating. All testing was performed by Optical Wave Labs in California. The original test certificate will be included with the mirror when purchased. The mirror was ground by Optical Wave Labs as well. This is a high quality mirror, that has been finished, tested, and aluminized by a professionals in the United States. If you are going to build a 12.5 inch scope, this is the mirror to use! To purchase this mirror, it would cost you between $1000, and $1500, even locating a full thickness Pyrex blank is hard to do anymore. Asking $800.00. I am no longer interested in Astronomy, (I was going to build a scope out of this mirror), and the mirror is now up for sale, or trade, for radio gear. I will consider any like value trade for this mirror. The mirror is in mint condition, not near mint, but mint condition...Unused, unmounted, and still packed in the original shipping box from the lab that ground it. What have you to trade for it? I will pay shipping/Insurance for the mirror within CONUS, you pay shipping/insurance within CONUS for your item. Looking for amps, rigs, test equipment, etc... What have you?

The answer is ? regardless of transmit filter selected, the upper end of audio in AM transmit is a pretty hard limit at about 2.95 Khz give or take a bit where the output drops off to better than 10dB below the mid range of the audio passband. At 3 KHz there?s virtually no audio at all. So no, there is no improvement in transmit bandwidth by using the FM filter for AM transmit. Which is a shame. The Flex radios (for example, and ignoring the rest of their faults) if properly driven and adjusted can produce very nice AM audio with a reasonable transmit passband for this mode. The K3 on the other hand generally gets a pretty bad (and perhaps deserved) rap on this in the AM community. It would seem since ESSB allows up to 4 Khz of audio bandwidth, that it might be possible to offer something in this range for AM and perhaps a bit more (adjustable to conditions) as well when using the FM filter for transmit. It would make a big difference over the 2.9+ KHz currently available. **** Please note, I am not trying to start yet another long thread on the whole bandwidth war discussion, or what the rules say or don?t or make anyone?s head explode. But it sure would be a good thing if Elecraft could see a way clear to improve the transmit fidelity in AM.

They are high fidelity, with lots of highs and bass. The Grado iGi sells for about $89. I am very fond of my big, on-ear Grado headphones. When my old ones died after 15 years, I upgraded to more expensive Grado phones. Or you can get some ear protectors at the hardware store and put them on over your earbuds. Those are around $20. wunder K6WRU CM87wj http://observer.wunderwood.org/ (my blog) On Mar 21, 2015, at 5:08 PM, J wrote: > I've been using Sony earbuds that are more like small speakers that lie in > the ear. > > Fidelity seems OK; highs and hiss are not emphasized. > > The problem with these earbuds is they let in too much background noise. > > I'd like some recommendations on earbuds with good CW performance, > sensitivity, low-hiss, that comfortably fit the ear canal to block out > noise. > > > > Thanks & 73 > > > > Jay > > W6CJ > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to wunder at wunderwood.org From jim at audiosystemsgroup.com Sat Mar 21 21:12:18 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 21 Mar 2015 18:12:18 -0700 Subject: [Elecraft] Best earbuds for KX1?

Shure and Etymotic Research are two excellent companies that make these sorts of earphones. In the pro audio world, they're called "in-ear," and are mostly sold to pop musicians for in-ear monitoring during live performance. They are used with UHF FM transmission systems, and because it's usually REAL loud on stage, they must be very good at sealing the ear canal. My favorite audio vendor is Full Compass, near Madison, WI. It's a family-run outfit that I used to compete with. I also like B&H in NYC. Check out their online catalogs for more options and pricing. 73, Jim K9YC From wunder at wunderwood.org Sat Mar 21 21:20:02 2015 From: wunder at wunderwood.org (Walter Underwood) Date: Sat, 21 Mar 2015 18:20:02 -0700 Subject: [Elecraft] Best earbuds for KX1?

I have an early pair of Ultimate Ears in-ear phones, but they start at $400 now. In-ear phones that seal in your ear canal can be tricky to fit. I seem to have very small ear canals, because the smallest options are a bit tight in my ears. That is why I suggested getting a pair of big yellow ear protectors over your earbuds. Works great. wunder K6WRU CM87wj http://observer.wunderwood.org/ (my blog) On Mar 21, 2015, at 6:12 PM, Jim Brown wrote: > On Sat,3/21/2015 5:51 PM, Walter Underwood wrote: >> There are earbuds that seal into the ear canal.

My K3 arrived last Wednesday and has since been set up and is now in use. It is a great transceiver I am enjoying getting to kno. I am using a Hampod to provide access via voice output and am wondering about the RX antenna button on the K3 front pannel. When I turn the RX antenna off and on, the Ham Pod announces "Pre-amp." When I press the Pre-amp button the Ham Pod annunces "Pre-amp enabled/ disabled" depending on which press of the button is active. Is the Pre-amp announcement on the RX antenna button what you see on the screen? I would have thought that the button for the RX antenna would be announced as the Rx antenna off/on.

So for example you could have it on with the rx antenna and off with antenna 1 and on for antenna 2 on a given band. Possibly when you turn the rx antenna on or off you are also changing the state of the preamp, and that is what the ham pod is announcing. In this situation, you would see both rx and pre appear on the screen if both were on. Vic 4X6GP/K2VCO > On Mar 22, 2015, at 4:53 AM, Ian Westerland wrote: > > Hi!

Which raises the question - is there a marked difference between the target practice protectors and the industrial protectors? I get my K2 audio via a Blue-tooth connection to my in-ear hearing aid devices so keeping "outside" noise out is important lest everything gets amplified to the same level. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From eric at elecraft.com Sun Mar 22 12:37:33 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Sun, 22 Mar 2015 09:37:33 -0700 Subject: [Elecraft] K3/0 Mini KEY jack not working?

I?m trying to find a schematic diagram and board layout for the Mirage D10210 432 mHz amplifier. I just bought one on eBay. Although it generates power into a dummy load, I think something?s wrong with it because it has no idle current. The amp is supposed to be biased for SSB but doesn?t seem to be. There are three ?thumb wheel? pots on the board, two of which appear to possibly be bias current settings for he pre amp and amp. However, tuning them does nothing to change the amp?s total current draw (which is 30 MA, presumably for the Power On LED). thanks in advance; please reply off the list. lew Lew Phelps N6LEW Pasadena, CA DM04wd Elecraft K3-10 / KXV144 / XV432 Yaesu FT-7800 Lew at N6LEW.US www.n6lew.us Sent from my Mac Pro 256-Array Supercomputer (9.42 teraflops) From elecraft at mailman.qth.net Sun Mar 22 14:49:40 2015 From: elecraft at mailman.qth.net (Harry Yingst via Elecraft) Date: Sun, 22 Mar 2015 18:49:40 +0000 (UTC) Subject: [Elecraft] KPA500 Proper Transformer Tap setting Message-ID: <1247167177.286344.1427050180894.JavaMail.yahoo@mail.yahoo.com> In the manual on page 9 it shows to set the tap for the line voltage, but on Page 17 under Note it states "The KPA500 operates to full specifications when the HV under full load isbetween 60V and 85V as shown on the LCD (Tap HV to display the voltageunder CW ?key down? conditions at full power).

The LSB side has significantly better bass response than the USB side. Likewise, USB has more highs and very little low end. It?s much like the response that occurs when the LSB/USB oscillator carrier frequencies are offset from their correct position relative to filter edges. Virtually anyone who has ever owned a KWM-2 or 75S-3x would understand what I?m talking about. The difference is apparent whether the sync detector is locked on a carrier or not. Wonder if anyone can comment on this (Eric?). It occurs with either the 13KHZ or 6KHz filters.

Good analogy, I'm left-handed ... you learn to adapt. Apple and Microsoft approached the market essentially orthogonally. Jobs wanted to control the entire user experience and as a result, the Apple hardware and software was tightly bundled, controlled, and protected. If Apple didn't make it or authorize its creation, it doesn't exist.

If that is the Red tap, then use that one. The two sentences are not in conflict. You should expect a major drop in HV on key-down due to losses in the power supply. This includes the components in the KPA500 (transformer, etc), the power cord, plug, wall outlet and wiring all the way to the main pole transformer. You can?t do much about most of this, but making sure the power cord can handle the current without overheating is a great idea. Of course this problem is worse with a 120V supply than 240V since the current is proportionately higher.

IF the wiring between the breaker panel and the outlet is under your control, it is a very good move to use bigger copper for that run. #14 is minimum for a 15A circuit, #12 for a 20A circuit, but going up to #`10 will reduce the IR drop under load. When doing the calcs, remember that the line current is NOT a sine wave, but rather pulses centered around the peaks of the waveform to recharge the input filter caps. That means that the voltage drop will be greater than if it were a sine wave. I have 240VAC in the shack to run my big tube amps, so I also run my KPA500 from 240V. 73, Jim K9YC From k2av.guy at gmail.com Sun Mar 22 16:35:38 2015 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Sun, 22 Mar 2015 16:35:38 -0400 Subject: [Elecraft] K3 Sync AM receive freq. response In-Reply-To: <6AA7413E-E3FC-4BF0-BD27-C5F6650A6CFB@tx.rr.com> References: <6AA7413E-E3FC-4BF0-BD27-C5F6650A6CFB@tx.rr.com> Message-ID: The appearance is that the filter being used for RX does not have its offset set for the center of actual measured filter band pass edges. 73, Guy K2AV On Sunday, March 22, 2015, GRANT YOUNGMAN wrote: > One of the things I?ve observed in sync AM receive, is the difference in > AF response between LSB and USB (selected by the shift control). > > The LSB side has significantly better bass response than the USB side. > Likewise, USB has more highs and very little low end.

Message-ID: Am contemplating a purchase of a DXE NCC-1 receiving antenna/noise phasing unit very soon (tomorrow, actually---so I will have it in time for the WPX next weekend) for use with my K3/P3/KPA500 and was wondering if anyone else in the group uses one and how they have it configured. Apparently I will either need to run it via my RX antenna jack or else with a sequencing unit (or RTR-1A controller that DXE also sells) if I want to run it inline with my main antennas. My main usage will be for the reduction of RFI that I am often subject to here in our condo complex (plasma or LCD TVs, wall warts and other electronic RF garbage producers nearby). I currently use an old JPS ANC-4 with its attached noise receiving whip that works fairly well---but could still be much better. (I don't plan to buy the active antennas that DXE also sells with or without the NCC-1; at least not for any foreseeable future). I also use my Elecraft PR6 6M preamp affixed via the XVTR or RX antenna BNC jacks and am wondering if I can run the NCC-1 through it with or without the PR6 being on (I have it wired so that the PR6 activates only when I am on 6M, IIRC)---but I am getting older these days and am more easily confused/dyslexic when it comes to IN/OUT jacks than I used to. Will it be fairly easy to run both together or will it require removing the PR6 if I want to run the NCC-1 through the RX ports? Any user comments or thoughts on the subject will be appreciated; I have seen a few YouTube videos on the NCC-1 and it looks like it can be very effective on QRN coming from one particular source (like my ANC-4 but even noticeably better). It certainly will be fun to see the noise disappear or fall dramatically on my P3, too! 73, Jeff, NH7RO K3/P3/KPA500 From emoss98133 at msn.com Sun Mar 22 17:11:23 2015 From: emoss98133 at msn.com (KD7PY) Date: Sun, 22 Mar 2015 14:11:23 -0700 (MST) Subject: [Elecraft] KPA500 Proper Transformer Tap setting In-Reply-To: <1247167177.286344.1427050180894.JavaMail.yahoo@mail.yahoo.com> References: <1247167177.286344.1427050180894.JavaMail.yahoo@mail.yahoo.com> Message-ID: <1427058683397-7600550.post@n2.nabble.com> You got me to check my KPA500, and with the yellow wire connected I showed at rest 73.7 v and 59.0 v key down, I changed to the next tap (red wire) and now it is 80.9 v and 65.9 key down, I think the amp has a shut down fault if the voltage goes over 85v I believe the assy manual says the the voltage should not go below 65v on key down. if it does you need to reduce the drive power to keep the distortion down.. my line voltage measured 240.2v so it seams the tap changed it about 7 v Ed -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-Proper-Transformer-Tap-setting-tp7600537p7600550.html Sent from the Elecraft mailing list archive at Nabble.com.

Line voltage varies through the day depending on the overall power load seen by the electric company in your area. So while you may measure 239v now, it may droop or go higher as the overall load varies during the day. That makes it difficult for us to give an absolute value for the tap setting, and also makes it difficult for you to say that any one is always the best. Try one for now, and if it works out in the long run, then keep it! If you start seeing HV high voltage faults, then drop back to a lower voltage tap. As K9YC says, you can help by using the biggest wires you can find, especially for the power cable from the wall to the KPA500. This is especially important at 110V, but applies to 220V as well. And, for the record, the KPA500 HV fault is at 90 volts. But you don?t really want to get there?

From: Jack Brindle To: Harry Yingst Cc: Elecraft Reflector Sent: Sunday, March 22, 2015 6:41 PM Subject: Re: [Elecraft] KPA500 Proper Transformer Tap setting One thing to remember is that the 240 volt power line is not constant voltage. Line voltage variesthrough the day depending on the overall power load seen by the electric company in your area.So while you may measure 239v now, it may droop or go higher as the overall load varies duringthe day. That makes it difficult for us to give an absolute value for the tap setting, and also makesit difficult for you to say that any one is always the best. Try one for now, and if it works out in thelong run, then keep it! If you start seeing HV high voltage faults, then drop back to a lower voltagetap. As K9YC says, you can help by using the biggest wires you can find, especially for the powercable from the wall to the KPA500. This is especially important at 110V, but applies to 220V as well. And, for the record, the KPA500 HV fault is at 90 volts. But you don?t really want to get there?

The two sentences are not in conflict. You should expect a major drop in HV onkey-down due to losses in the power supply. This includes the components inthe KPA500 (transformer, etc), the power cord, plug, wall outlet and wiring allthe way to the main pole transformer. You can?t do much about most of this,but making sure the power cord can handle the current without overheating isa great idea. Of course this problem is worse with a 120V supply than 240Vsince the current is proportionately higher. So, again, if the red tap gives you better output and keeps the HV within the 85Vspec under no-load conditions, use it. Make sure it meets both conditions, though. 73, Jack B, W6FBElecraft Engineering On Mar 22, 2015, at 1:10 PM, Harry Yingst wrote: My line voltage is 239 (which calls for the yellow tap)??but on Key down it sags to 59v With the Red Tap it only sags to about 66v (80.7 no key) So The proper tap would be?

I have owned a pair for twenty years, and still love them. They come with the 3-flange ear tips, but are best used with deep canal ear molds. These are individually molded at an audiologists, and the resulting fit can offer up to 35dB or more broadband attenuation to ambient noise. This allows the use of moderate drive power and by suppressing ambient acoustic noise really opens up the noise floor for analysis. For those who desire a more modest model, the next best alternative IEM I have found is the Audio Technica ATH-ANC23, which has Active Noise Cancellation (ANC) which works well. Although the amount of noise cancellation they offer is less than some Bose models, I find the audio quality to be superior to the Bose. I have used these in many multi-op contests where an SSB op was yelling "AGAIN, AGAIN???" for what seemed like hours next to me while I tried to copy weak CW, and the ANC really helped! For the record, the very best audio quality I have heard from an IEM comes from the Sennheiser IE800s. They rival the best over-ear models and approach the quality of the Stax electrostatics at lower volumes.

The K3 has adequate mic gain range to handle most any microphone. I believe the HC-7 element has relatively low output, so you may have to use the High mic gain range.

For non-synch AM, the center is significant as you state. The filter slope on the low frequency side will not be the same as on the high frequency side. Even though the 13kHz filter theoretically has zero offset, you may find a better balance for the bass response by experimenting a bit with the offset value for that filter. 73, Don W3FPR On 3/22/2015 4:50 PM, Grant Youngman wrote: > That could be.

Likewise, USB has more highs and very little low end. It?s much like the response that occurs when the LSB/USB oscillator carrier frequencies are offset from their correct position relative to filter edges.

However, like any electret element it requires some TX EQ to be effective. The low end typically needs to be rolled off [-6 dB @ 200 Hz, -16 @ 100 and 50 Hz] to prevent "rumble" and wasted transmit power while the high end generally needs boost [+3 dB @ 1600, +5 dB at 2400, +6 dB at 3200] for "articulation" (as paging and PA system designers have known for decades). The HC7 has that contour already 'built-in' - the only thing needed is to disable the "bias" (DC voltage) on the mic jacks and select a little higher gain for the mic preamp (an electret has about 26 dB more output than a dynamic mic like the HC7). 73, ...

There was way too little mike power to move the needle. I then bought the Pro-Set that Elecraft sells, and it came with the little "iC" sticker indicating the Icom version. I sent my Pro7 back for a swap of elements to the iC electret, and everything worked fine. BTW, the Elecraft hand mike (MH2) also worked fine, and one of the guys at Elecraft told me it had an electret element. That said, I am certain the same problem did not occur when using the mike with the K3 itself. Plenty of gain with either version mike. 73 de Brian W3BW Brian F. Wruble, C.F.A.

The 13 KHz filter has more than adequate bandwidth for Sync (USB/LSB) AM. Even if it is off by as much as 2 KHz the bandwidth is enough to pass the full 4.5 KHz recovered bandwidth. The upper/lower edge is determined by the DSP characteristic, not the crystal filter bandwidth. Looking at an audio spectrum display with "hold" it's fairly clear to see there is roughly a 50 Hz difference in the lower frequency limit between "LSB" and "USB" in Sync detection while by ear there is a qualitative difference ("more open") high end in "USB". There is no perceptible difference when moving the FM filter offset from limit to limit. The difference persists even when forcing use of the 2.8 KHz crystal filter. It's purely an issue in the DSP function. 73, ...

I realize this is totally subjective because I don't even have the test equipment to "run the numbers" but from an operators standpoint, it was just amazing to be able to copy weak Russians fluttering over the pole after this weekend's flare incident. I'm in Texas and we don't see "East coast" conditions too often so I was really concerned that conditions would be too frustrating to hang in the contest. I don't recall ever getting pushed off a CQing frequency by a close by station other than one guy's terrible key clicks that covered 25 Khz. I operated 23 of the 24 hours and was relatively ready to continue but the rate had completely dropped into the tank by the last hour so I hit the sack. Beside the RX side improvement, the CW keying is now perfect (perfect for me means not a bit choppy at 35+ WPM speeds) and reflects exactly the weighting my logging software tells it. This is another huge improvement after having to previously play with the weighting to get even semi-reasonable code out at 35+. These seem to be big steps forward for the K3 and completely satisfies what I'm looking for in a rig.

Not really expecting to hear something like that so now I am scratching my head wondering whether or not to jump in anyway or hold off another year if/when the improved model hits the shelves. Some of what you wrote is a bit over my head but I got the general gist of it; obviously there is still room for improvement (perhaps in the quality control department if there is such a broad range between various units?). Perhaps you got the one and only Edsel of the lot, though considering that most every other review I've read has been overwhelmingly positive. I thought the YouTube demonstrations were compelling; especially the one with two strong BCB stations on the same frequency---with either one being able to be nulled out almost completely. Night and day! I'm not sure whether my simple condo antenna setup will be a better candidate or not compared to yours and others who have DXE noise antennas set up far away from their shacks and TX antenna(s). Right now I'm using a variable-length inverted U dipole (10-12-15-17-20M) with the top horizontal portion/feedpoint only about 20 feet above ground. It is suspended by some fiberglass poles mounted at the top of a wooden beam over our front porch balcony and I am able to work plenty of DX with the help of Ion, the Propagation God and the 650 watts that my KPA500 provides. While far from ideal at least I am able to enjoy the hobby much more and utilize my entire K-line again since departing KH6 (DX paradise) three years ago. As I mentioned before, my noise antenna so far is only the three or four foot whip atop my ANC-4 and most of the time it works from almost fair to very good---depending on various factors and the type of noise involved (usually next door or downstairs TV). My noise antenna is only about 20 feet away from my balcony dipole (whose ends are hanging down so it has both vertical and horizontal components---probably helping my signals get beyond the surrounding obstacles so close to me here. I am also just about to finish building my first STL (magnetic loop antenna) for 10-20M which are the bands I operate 98% of the time, too. I have been taking my time constructing it carefully so that it should perform at optimum levels for what it is (I rolled a 9.5' copper pipe 1.125" OD into a circle and it has only two silver brazed connections for the vacuum variable capacitor clamps). This loop will probably end up replacing the inverted U and also be less susceptible to the RFI that I am now experiencing---but I want to go the extra mile with my station anyway. I plan to roll additional loops (recently purchased a Hulk tubing roller that works very well) so my noise antenna will follow in my TX antenna's "footsteps" soon. I can put that 2nd (noise) loop out on our cramped back balcony and hope for the best. I don't really know much about how the coupling (or lack of) factors into all of this but it will be interesting to see how two STLs will perform with an NCC-1 and also the diversity feature in my K3. ( I also will upgrade both main and sub synthesizers, too later this year after every little bug is worked out and the backlog of orders gets caught up). One last thing I'll mention before I QRT and make a run to Home Depot (building a wooden stand for my loop); most of my noise is up on the higher bands---unlike your 160M operation that you used the NCC-1 for---so maybe I will enjoy better results for this particular usage? Anyway, I think I will go ahead and take the plunge today and try it out despite your helpful warning---curiosity might be getting the better of me... I already have some gold-plated BNCs and RCA phono cables that I can rig up so I will try it hooked into the KXV3A ports (I'll just remove the PR6 as nothing's happening on 6M now anyway) as well as make a cable for the PTT line. I hope to get this up and running by the upcoming WPX this weekend---either way, I will follow up with my impressions here thereafter in case other K3 owners are considering adding one of these to their ham shack. Thanks again for taking the time to explain your experience, Hank and if mine doesn't cut the mustard I can't say you didn't try to warn me, hi hi! 73 to you and the Elecraft forum for listening to my rambling, Jeff, NH7RO > From: pfizenmayer at q.com > To: cathrowinternational at hotmail.com > Subject: Re: [Elecraft] Anyone using a DXE NCC-1 with K3? > Date: Sun, 22 Mar 2015 16:32:46 -0700 > > I see I did not address how it was connected - Like you , all the possible > configurations with the KXV3A and aux ant input to sub rx give you a > dizzying set of choices. > > In my case I wanted to null against my TX antenna.

The limitations on what can be achieved with noise cancellation units like this is NOT inadequacy of the design of the box. It is entirely dependent on the noise sources, their locations, your main antennas, and what you can do for sense antennas. You can wait forever for "an improved model," or you can study how antennas work and how signal cancellation works. I suggest the latter course. You may also benefit from studying k9yc.com/RFI-Ham.pdf, which is a tutorial about RF noise and how to reduce it, among other things. 73, Jim K9YC From cathrowinternational at hotmail.com Mon Mar 23 15:31:14 2015 From: cathrowinternational at hotmail.com (Jeff Cathrow) Date: Mon, 23 Mar 2015 14:31:14 -0500 Subject: [Elecraft] Anyone using a DXE NCC-1 with K3?

Anyway, my apologies to all concerned. I hope it is all clear to everyone now and that the NCC-1 discussion can continue further without much distraction. When I ordered the NCC-1 a little while ago DXE said that it would be a whole new design that they would be coming out with---not a modification of the NCC-1 per se, FWIW. I decided to try one out this week as I otherwise might be "waiting for Godot..." (indefinitely). I also ordered a "Receiver Guard 5000" to put into the noise antenna line which protects the receiver further while transmitting QRO as I often do; a bit of extra insurance for my precious K3. 73, Jeff, NH7RO > From: pfizenmayer at q.com > To: jim at audiosystemsgroup.com > CC: cathrowinternational at hotmail.com > Subject: Re: [Elecraft] Anyone using a DXE NCC-1 with K3? > Date: Mon, 23 Mar 2015 12:07:07 -0700 > > > > Jim - I am really PO'ed that a private message to this guy is now on the > Elecraft reflector - I am even more PO'ed that you chose to infer that I > don't know what the hell I am doing, and especially on an open reflector . > > For your information apparently you do not have the whole story, unless Jeff > sent you my original message.

If people do not like the feature set of a product, people will not purchase it. If Elecraft does not appeal to the market segment that buys a radio for the features they offer, they will soon begin to dwindle and ultimately die. Then there are zero resources for anything. I personally think a better CW code reader would be a better use of resources compared to AM. Do you think new buyers of radios are more interested in AM performance, or the ability of the radio to decode CW (for those that don't know CW). Of those two categories of buyers, which one has a larger number of people? A company (or senator, or representative, or president, or any elected official) MUST focus their efforts, or fall prey to competition that does focus on the majority. If not, they perish. Technology, while important, is not the only factor. There are more CW operators in the world than there are AM'ers. That fact makes Elecraft's decision easier. Focus on CW as opposed to AM. They did this very same thing with the recent release of the synth. The new synth makes little difference on SSB (and AM for that matter) and has it's impact on CW. BUT not that much of an impact on a band that is not crowded. It only shines on a crowded CW band like Sweepstakes, 160 meter contests, and the like. My interest is CW, without a computer. Hence my decision to go with the K3. I had a TS-480, and it worked great and met my CW needs. There was no real reason to change to a K3, as for my style of operation, the 480 was good. But the 480 did not have a panadaptor or a roofing filter, that was important to me. So, Kenwood lost a customer, and Elecraft picked one up. Those are the realities of the market. If Kenwood loses to many customer, the will go the way of the Globe's, the Vikings, the Drakes, the Eicos, the Heathkits, the Hallicrafters, the Collins. The list goes on and on and on. BTW, I am an old phart too.

If people do not like the feature set of a product, people will not purchase it. If Elecraft does not appeal to the market segment that buys a radio for the features they offer, they will soon begin to dwindle and ultimately die. Then there are zero resources for anything. I personally think a better CW code reader would be a better use of resources compared to AM. Do you think new buyers of radios are more interested in AM performance, or the ability of the radio to decode CW (for those that don't know CW). Of those two categories of buyers, which one has a larger number of people? A company (or senator, or representative, or president, or any elected official) MUST focus their efforts, or fall prey to competition that does focus on the majority. If not, they perish. Technology, while important, is not the only factor. There are more CW operators in the world than there are AM'ers. That fact makes Elecraft's decision easier. Focus on CW as opposed to AM. They did this very same thing with the recent release of the synth. The new synth makes little difference on SSB (and AM for that matter) and has it's impact on CW. BUT not that much of an impact on a band that is not crowded. It only shines on a crowded CW band like Sweepstakes, 160 meter contests, and the like. My interest is CW, without a computer. Hence my decision to go with the K3. I had a TS-480, and it worked great and met my CW needs. There was no real reason to change to a K3, as for my style of operation, the 480 was good. But the 480 did not have a panadaptor or a roofing filter, that was important to me. So, Kenwood lost a customer, and Elecraft picked one up. Those are the realities of the market. If Kenwood loses to many customer, the will go the way of the Globe's, the Vikings, the Drakes, the Eicos, the Heathkits, the Hallicrafters, the Collins. The list goes on and on and on. BTW, I am an old phart too.

Some oh-not-so-old Kenwood radios are excellent on AM. The Orion I/II is truly an excellent AM transmitter (I owned 3 of them, and even now they aren't exactly shabby on any other mode). The Flex-most-anything can be broadcast quality (perhaps you should seek one out). There is a large, vibrant, and growing AM community (who's technology is far younger than CW). Universally, they dis the K3 for its poor (relatively) AM performance, and avoid it (in some quarters with great disdain) for that reason. Frankly, I'm getting too old to keep hauling around a Globe King 500 and a Globe Champion 300. Given the K3 is an SDR -- there is no reason (well, other than "mode" bias perhaps and a few (100/1000) lines of code that it could not also meet the needs of the AM community and become a popular radio there. I get exceedingly tired at being scolded for being an old f*rt, simply for enjoying an operating mode that is younger than CW. (And, by the way, I like CW too, and SSB, and various digi modes from time to time). There are many groups of hams involved in many different aspects of the hobby. I'd respectfully suggest we might want to be a bit more respectful of ALL, even if they don't fit with our personal ham radio ideology. But that's another subject for a different venue. .. :( Grant NQ5T Sent from my iPhone > On Mar 23, 2015, at 4:28 PM, jim wrote: > > A more gentlemanly form: > > Elecraft needs to remain competitive in the market. > > They have limited resources to advance the art.

Small, simple, a game-changer, got the job done. It's a delight to use. Drake didn't leave the Ham radio market because of AM, or focus on AM, or lack of focus on AM. They probably left because in the end they couldn't price compete with relatively cheap offshore radios. And decided the cable TV market was more profitable and could increase the length of yachts, whatever. The 1-A was a benchmark. SSB only. CW not even considered, so don't blame it on AM or not. But a marvelous radio, ignored for its novelty by a lot of hams. Now, they're expensive for a reason. It was the 2-A and 2-B that made the transition. Beautiful radios. The R-4B for example (properly aligned) is one if the VERY best CW/SSB radios from the era - in many ways better than Collins. And a pretty good AM receiver for its genre.

The question is whether they should bother to support wider AM ("Enhanced AM") to 4 KHz audio bandwidth as they do with ESSB. I'm of the opinion that transmit audio bandwidth needs to remain consistent with "communications quality" which is defined variously as 2.7 or 3.0 KHz depending on whether the definition uses "highest modulating frequency" or "necessary bandwidth". As an FCC official famously said at the FCC Forum in Dayton, "If you guys what to play with Hi-Fi, apply for a broadcast license." The use of excessive bandwidth is not simply bad manners, it is against the rules. 73, ...

Because both receivers are tuned by VFO A when in diversity mode, you must revert to the operating techniques needed for a single receiver radio. You will be listening to the DX station on VFO A and searching for the station that has successfully broken through the pile-up with VFO B, which can be tuned independently of VFO A. VFO B controls the transmit frequency in split operation. 1. Tune into the DX station with VFO A. 2. Tap A>B to transfer VFO A to VFO B. 3. Start up diversity reception by holding SUB for more than two seconds. 4. Hold SPLIT to enter split mode. Now you will be transmitting on VFO B. 5. When you hear the DX station go back to a station in the pile-up, hold the REV switch to reverse VFO A and VFO B temporarily. Quickly search through the pile-up using VFO A to find the station going back to the DX. When you find it, release REV and get ready to call the DX on the next over. 6. You may also hold B SET to enter b SEt mode. You will hear the Main receiver in the left ear and the Sub in the right ear. This temporarily overrides diversity mode allowing you to hear the DX station on VFO A and the pileup frequencies on VFO B.

How do I get it to work on both waterfall screens?? Second, I run the K3 in conjunction with my Flex5000A.? I notice that the Flex waterfall appears to have considerably more detail and a more robust color scheme than the P3.? The Flex also has more detail (I see signals on the Flex that barely come up on the P3).? I switch between the same antenna, so that should not be a factor.? Is there a sensitivity adjustment on the P3 that I need to play with?? If not, I must admit that the P3 waterfall does not appear to perform nearly as well as the Flex.? Finally, once you assign a function to an FN series button, is there a way to delete the assignment, short of assigning another function over it?? Thanks for your input. ?? ?K0GFY? R.

All of your concerns are answered in the manual. The P3 is a very powerful and versatile product, and the SVGA board increases its capabilities. It's scan width can set to any value between 2 kHz and 200 kHz. Amplitude range can be set between about 10 dB and 80 dB. The unit can be calibrated to the voltage at the K3's input terminals (a signal generator is required). Both amplitude and waterfall can be averaged or not, and average settings are adjustable. There are separate settings for the P3 display and the external display. The frequency resolution is quite good, and is improved by a factor of 10 or more by the separate FFT used to drive the SVGA output. Here's a link to some lab quality spectrum measurements I've done with my P3/SVGA. k9yc.com/FTDX5000_Report.pdf The P3/SVGA combination has frequency resolution that is roughly 100X better than my HP 8509D. 73, Jim K9YC From esteptony at gmail.com Tue Mar 24 16:05:05 2015 From: esteptony at gmail.com (Tony Estep) Date: Tue, 24 Mar 2015 15:05:05 -0500 Subject: [Elecraft] Don't have a 50W dummy load In-Reply-To: References: Message-ID: Aha, I did have all the files for version 4.83.

Ridge Equipment has a 50 ohm 75 watt dummy load good up to 1.5GHz for $11.95, but you will need an adapter for UHF connectors so that is an additional $5. See https://www.ridgeequipment.com/store/dummyloads.html. If ever you run into a problem, the first check is to see what happens when you transmit into a dummy load. That removes many variables - like RFI problems and antenna problems. It is the first check I recommend. If the rig works into the dummy load, you need to look for the problem somewhere other than the rig. I have had rigs sent to me for "repair" only to find that there is nothing wrong. The resulting repair charge is greater than the cost of a good dummy load. If you look for one at a hamfest, take your ohmmeter along to check if it is still a 50 ohm load - some are burned out from excessive power. 73, Don W3FPR On 3/24/2015 3:25 PM, Tony Estep wrote: > Well, now I downloaded the new firmware, only to discover that I have to do > the 50W calibration.

The same REF LVL and SCALE settings are applied to both the spectrum and the waterfall displays. For further details, see the PX3 User's Manual section called "How to Set Up and Interpret the OX3 Display". To erase a FN key setting, use the FN Erase menu function.

I have a homebrew gallon size "Cantenna" that I built many years ago. I happened along some large wattage carbon resistors (about 1/2 inch in diameter and 2.5 inches long - maybe 25 watts each) and used several of them in parallel to create a 50 ohm load ( I recall it was 11 560 ohm resistors). This was when I was a "cash-flow restricted ham". I measured mine recently with my antenna analyzer and was surprised to find it was still less than 1.15 SWR up through 30 MHz. This is despite reports that the old 'trusted' carbon carbon resistor changed value with age. In any case, I am happy with the results of that old homebrew dummy load. In the same batch of resistors, I also had many 1500 ohm units. I was going to put 30 of them in parallel for a dry dummy load, but the lead length was excessive and the leads gave it an inductive characteristic above 14 MHz. The original Cantenna used a single resistor which apparently did change in value with aging. 73, Don W3FPR On 3/24/2015 6:44 PM, Dave KW4M wrote: > It's a good idea to check the resistance of any used dummy load, especially > one that has some age on it. > > The resistance of my 30+ year old Heath Cantenna gradually reduced to 42 > ohms.

The ultimate BW of your receiver is set by the DSP and noise power is "sort of" proportional to BW. The purpose of the roofing filters is to protect the ADC sampler at the head end of the DSP from very strong signals that could drive it to saturation. Noise, other than atmospheric and galactic, needs to be attacked at the source. Like getting rid of your switching wall warts and power supplies. So long as the atmospheric noise is not saturating the ADC, reducing the DSP BW is the only really effective way to reduce it's impact, and that's a lot easier on CW than on SSB. Different roofing filters are not likely to make much difference at all unless they're more narrow than your DSP setting.

The ultimate BW of your receiver is set by the DSP and noise power is "sort of" proportional to BW. The purpose of the roofing filters is to protect the ADC sampler at the head end of the DSP from very strong signals that could drive it to saturation. Noise, other than atmospheric and galactic, needs to be attacked at the source. Like getting rid of your switching wall warts and power supplies. So long as the atmospheric noise is not saturating the ADC, reducing the DSP BW is the only really effective way to reduce it's impact, and that's a lot easier on CW than on SSB. Different roofing filters are not likely to make much difference at all unless they're more narrow than your DSP setting.

There is also the "NR" noise reduction feature which may be useful. However on CW I find that narrowing the PBT bandwidth cuts out a lot of the band noise. As someone else stated, a roofing filter is not going to help you with this sort of problem; a roofing filter is to protect against strong stations on nearby frequencies so you don't get problems like AGC pumping and undesired mixing products. 73, Matt VK2RQ > On 25 Mar 2015, at 1:49 pm, Fred Jensen wrote: > > Joshua, Probably not.

Works well, but has to be retuned for each band of course, and the resistance varies with brightness. Because of the variation, do not use with an automatic antenna tuner or the tuner will constantly seek a correct tune.

Yes, TX CAL will do that. You need a good 50 ohm non-reactive dummy load good to 54MHz. Light bulbs worked well with old transmitters that had an output circuit that could match most anything. We did not need tuners back then - but then along came limited range transmitter output circuits which sometimes needed a tuner, but today's transmitters need to see a 50 ohm non-reactive load if they are to work properly - and then tuners became essential - they just moved the matching network out of the transmitter and put the equivalent into another box called an antenna tuner. 73, Don W3FPR On 3/25/2015 2:25 PM, Bob Gibson via Elecraft wrote: > HOW ABOUT A LAMP WITH 100 WATT BLUB, THATS ALL US OLD GUYS HAD! 73s Bob W5RG > > From fcady at ece.montana.edu Wed Mar 25 17:14:43 2015 From: fcady at ece.montana.edu (Cady, Fred) Date: Wed, 25 Mar 2015 15:14:43 -0600 Subject: [Elecraft] text display on p3 external monitor In-Reply-To: References: Message-ID: <31B0BCE89606784FB09EF0C6CF94794F045C5ECE91@coeexch1.coe.montana.edu> Hi Paul, It's in the P3 SVGA sub-menu (SVGA data), Table 9-8, page 255. :-) Cheers and 73, Fred KE7X Author of: "The Elecraft K3: Design, Configuration and Operation 2nd ed" "The Elecraft KX3 - Going for the summit" "The Elecraft KPA500 and KAT500 - the K-Line Dream Station" Printed, coil bound copies of these are all available at www.elecraft.com KPA500 and KAT500 Quick Set Up Guide http://www.ke7x.com/home/k-line-introduction-and-set-up-guide KAT500 and KXPA500 Tuner Operation http://www.ke7x.com/home/kat500-and-kxpa100-tuners > -----Original Message----- > From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of > Paul VanOveren > Sent: Wednesday, March 25, 2015 12:38 PM > To: elecraft reflector > Subject: [Elecraft] text display on p3 external monitor > > Somehow I turned off the text display on the bottom of the P3 external > display.

It was sourced in Santa Cruz YIPPEE! Confirmation was the new charge to the credit card. The two new synch cards, PR6-10 and P3SVGA are on their way!!! I ordered 23 Feb, after Elecraft survived a massive weekend ordering frenzy. But after checking on it this morning (expecting/hoping for "Out for Delivery"), for reasons only known to UPS, the package is now sitting in South SF limbo for "at least a day". Bubble deflated. It's a small package so easily fitted into nooks, but no reason given, it's a UPS Ground thing. That's only a 3 hour drive from here, plus or minus Bay Area nonsense. I mention this as a status update so others can maintain their hope that the back order is indeed being pushed out the Elecraft doors as quickly as they can. Hang in there!

My current HF antenna is a Barker and Williamson ACS110, a terminated end-fed Vee which is similar to the Radiowavz EFT-110. I wasn't expecting a lot from this type of antenna and my three watts. It's more suited to 100-1000 watt operation, MARS, E-Comm, it covers all of 1.8-30 MHz. I was pleased that I did not need the internal KX1 ATU running on 40, 30 and 20 M with my antenna. In a week of very casual operation, I worked more stations on the KX1 than I had since its completion in 2005. Most contacts were CONUS with the Exception of HI, and several contacts were QRP-to-QRP on 40 and 30M. I was pleased with the audio and filtering in the KX-1, whether it was driving earbuds or an amplified computer speaker. The adjustable crystal filter produced non-fatiguing CW copy. It was enjoyable to put the fancy radio station away and get back to basics. 73 Jay W6CJ From elecraft at mailman.qth.net Wed Mar 25 20:51:58 2015 From: elecraft at mailman.qth.net (Bob Gibson via Elecraft) Date: Thu, 26 Mar 2015 00:51:58 +0000 (UTC) Subject: [Elecraft] Fw: Fw: Don't have a 50W dummy load In-Reply-To: <551347B4.6080007@foothill.net> References: <551347B4.6080007@foothill.net> Message-ID: <1358386164.1784905.1427331118349.JavaMail.yahoo@mail.yahoo.com> ?You guys are right!!

If the logging program is not active, then SteppIR must poll for band information - there is a setting in the SteppIR application to allow or disallow the SteppIR direct polling for K3 data. Check the SteppIR information for the details. It does come down to the fact that RS-232 buss definitions do not allow for multiple drivers on a signalling line. When in use with other com port oriented applications (such as a logger), the SteppIR controlled must disable its drivers (but not the receivers). When the logger application is not present, the SteppIR controller must issue commands (A driver must be enabled) to the K3 and apparently in your case, that is not happening. Check your settings for the SteppIR application. 73, Don W3FPR On 3/25/2015 9:32 PM, Rick Tavan wrote: > All of a sudden, my SteppIR stopped tracking my K3 even though the SteppIR controller was in General Mode.

I have a small transmitting loop on ANT1 and a horizontal wire loop on ANT2. The STL has an ATU for tuning the loop physically, and thus I should not be using the ATU on the KXPA100/KX3. I'd like to disable/bypass the ATU for this antenna, but the ATU is necessary for the horizontal wire loop, so I would like to have it enabled on the other antenna. Currently I have to be careful when switching antennas not to short-press the button as it will tune on the STL if I do, which is non-ideal. I also have to clear all tuning every time I turn on my radio to make sure I haven't fat-fingered and tuned up the wrong antenna. Having the ATU setting by antenna specific would make this significantly easier. If this isn't currently possible, I submit it as a feature request.

One possible cause: The communication chips that send and receive this sort of message have a little bit of on-board memory, which is used as a ring buffer. Sometimes, due to a static blip or an accident of timing or whatever, these buffers can get hosed. A hardware reboot will fix it. This might have been what happened in your case; the computer and the steppir chips were working okay and could talk to each other, but the k3 had gotten into a frozen state. This sort of thing can also be caused by rf in the shack. Anyway, you're up and going, so all is well. 73, Tony KT0NY On Thu, Mar 26, 2015 at 10:57 AM, Rick Tavan wrote: > Thanks, Don.

I have experienced this behavior. Do you have more than one SteppIR controller? Are they slaved together and is the master controller the older style and the slave controller(s) the SDA100 style? If yes, then the problem may be caused by the fact that the old controller resolves frequency to 10Hz and the SDA100 resolves to 1Hz. Logging programs tend to request frequency information every second or so. The SDA100 display will immediately display the exact frequency. But a second later it will correct itself to the 10Hz resolution of the master controller. 73, Mike K2MK Rick Tavan N6XI wrote > Thanks, Don.

I will give away a set of 17 resistors to anyone that mails me a postage paid, 4 by 6 inch, padded envelope. I think two stamps will do it...maybe three if you are having doubts.

I presume I would need to set the BPS to 4800 and either poll the K2 or turn AutoInfo on for this to work. The assumption here is that the RJ45 TxD/RxD lines are carrying standard serial data at standard bit rates.

In-Reply-To: References: Message-ID: No, but if you change bands on the K2, a quick tap of the "dit" paddle will trigger the frequency counter in the KXPA100, and instantly recall the band pass filter/antenna selection/tuning solution for the new frequency. If you want the greater degree of integration that you mention below, you need to look at the KPA100/KAT100. That said, it may well be possible for Elecraft to implement the sort of integration you mention between K2 and KXPA100; it would come down to whether they see it as a worthwhile investment of engineering resources. 73, Matt VK2RQ > On 27 Mar 2015, at 6:45 am, Jessie Oberreuter wrote: > > > Will connecting a K2's serial TxD/RxD lines to the KXPA100 (over the RJ45 jack) allow the KXAT3 to automatically follow band and VFO changes? I presume I would need to set the BPS to 4800 and either poll the K2 or turn AutoInfo on for this to work. The assumption here is that the RJ45 TxD/RxD lines are carrying standard serial data at standard bit rates. If true, I would also expect to be able to talk to the K2 through the KXPA100 just as I would talk to a KX3. > ______________________________________________________________ > 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 matt.vk2rq at gmail.com From karlerb7 at gmail.com Thu Mar 26 17:25:19 2015 From: karlerb7 at gmail.com (Karl Erb) Date: Thu, 26 Mar 2015 17:25:19 -0400 Subject: [Elecraft] [K2] voltage/current sensing K2 SN 4277 Message-ID: Display now reads E00.7 i0.06 and low batt following my poking around inside.

Check to see if the voltage at U6 pin 5 is the same as at U3 pin 7 - it should be. In this case, the fact that the display indicates a low voltage says either that the trace between U3 pin 1 and U6 pin 5 is broken, or that the U6 pin 5 input is faulty. As for the display of current part, either Q11 is misbehaving or there is something wrong with R7 (check for solder bridges). That may be correct if part of the receiver is not functioning. The normal current draw is 0.240 to 0.270 amps dependent on the options installed. You did not say what your "poking around inside" consisted of. If you induced static charge on some of the pins of U6 that could be the cause - OTOH, if you were soldering, look for solder in places where it should not be (solder bridge). 73, Don W3FPR On 3/26/2015 5:25 PM, Karl Erb wrote: > Display now reads E00.7 i0.06 and low batt following my poking around inside.

If you clear the memories for ANT2 using the KXPA Utility, put the ATU in bypass, select ANT2, tune your loop for low SWR at the middle of the band, then put the KXPA100 into mode MAN. While transmitting, with low SWR because you tuned the loop, press the ATU TUNE button. The KXPA100 will measure the SWR and find that it's less than 1.2:1 and will store "bypassed" result as the desired ATU tuning solution for ANT2 on that frequency. You can watch this with the KXPA Utility Operate page if you want to make sure that it's "bypassed". Repeat this on each band where you use the loop. Thereafter, keep the ATU in mode MAN, and when you transmit on ANT2 on any frequency, the ATU will look for a memory nearest the transmit frequency. If there's only one mid-band tuner solution saved, that's the one it will find. And because that antenna tuner setting is "bypassed", the ATU will load the "bypassed" solution. If the SWR becomes suddenly high because you didn't tune the loop, in mode MAN, the ATU will not attempt to retune. It'll fault with a high SWR fault. If the ATU is put in mode AUTO, it will attempt to retune based on a high SWR. In your situation, you'd want to stay in mode MAN. 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Orman Sent: Thursday, March 26, 2015 7:54 AM To: Elecraft Reflector Subject: [Elecraft] Per antenna ATU settings for KX3/KXPA100 Is it possible to bypass the ATU on one antenna but not the other? I have a small transmitting loop on ANT1 and a horizontal wire loop on ANT2. The STL has an ATU for tuning the loop physically, and thus I should not be using the ATU on the KXPA100/KX3. I'd like to disable/bypass the ATU for this antenna, but the ATU is necessary for the horizontal wire loop, so I would like to have it enabled on the other antenna. Currently I have to be careful when switching antennas not to short-press the button as it will tune on the STL if I do, which is non-ideal. I also have to clear all tuning every time I turn on my radio to make sure I haven't fat-fingered and tuned up the wrong antenna. Having the ATU setting by antenna specific would make this significantly easier. If this isn't currently possible, I submit it as a feature request.

"Lord willin' and if the creek don't rise", I will be at FDIM again this year. Hoping to see you there. Your power output with that supply voltage is not unexpected. Yes, you could install the KX1 power mod to your KX1. If you always operate with the battery, that would be an OK thing to do, but if you also operate with a higher voltage supply, reduce the power to less than 5 watts with the variable R4 pot (its adjustment slot is reachable through the hole in the bottom cover and in the KXAT1). The technique for removing components from the board without professional grade desoldering tools is to clip the leads or crush the component (leaving enough lead to grasp with pliers) and removing the leads one at a time. Clean up with solder wick, and if there is still solder in the hole, heat the solder pad and insert a wooden toothpick or stainless steel needle into the hole to clear the solder. 73, Don W3FPR PS: "if the creek don't rise" is indeed a valid consideration here - our driveway passes over a creek, and in a heavy rain, it has been known to overflow the driveway - it has only happened 4 times in the past 14 years we have been here, but who knows when the next very heavy rain will occur.

In-Reply-To: References: Message-ID: I have local noise problems which come and go depending on time of day, day of week etc. I didn't like the idea of having a noise cancelling device in the high power transmit path, so picked up a DX Engineering NCC-1 which is perfect for use with my K3, inserted between the antenna OUT and antenna IN jacks. I have a horizontally polarized loop which I use as the RX antenna on the K3 when I need to fight noise. A vertical doublet antenna is used as the transmit antenna, which serves as the noise sense antenna in receive when the NCC-1 is active. To do this, the loop antenna goes to antenna port A on the NCC-1 (receive antenna input), K3 antenna OUT (from the transmit antenna) goes to antenna port B on the NCC-1 (noise antenna input) and the output of the NCC-1 goes to the K3 antenna IN. K3 KEY OUT goes to NCC-1 T/R CTRL to put it in bypass when the K3 is keyed. Now I have 3 choices: 1. If I then select the RX antenna on the K3, the NCC-1 is inserted and I use the quieter loop antenna for receive while nulling noise with the NCC-1 controls. 2. If I don't select the RX antenna on the K3, the NCC-1 is bypassed, and the transmit antenna is used for receive. 3. If I select the RX antenna on the K3, but turn the NCC-1 OFF, then I receive on the loop antenna, but the signal passes straight through the NCC-1 from antenna port A to the output without modification (sometimes that's all that's needed, it's much quieter than the vertical when it comes to the nearby noise pollution sources). The NCC-1 can provide a very deep null on the receive loop antenna for vertically polarized noise which is "heard" better on the vertical. The trick is to correctly balance the levels of the two antenna inputs on the NCC-1. The balance and phase controls are very precise and repeatable, and the phase control has a wide range. Having the P3 to look at helps in identifying the noise and finding what can be a very sharp (but deep) null. There are complications. One is that when the NCC-1 is active I need to disable full QSK on the K3 in CW mode so that the internal bypass relay in the NCC-1 doesn't make a lot of noise as it follows the keying. The other involves antenna tuners. I use a KAT500, and if a frequency change causes it to recall new L and C settings then the NCC-1 phase setting may need to be touched up because the phase of the noise signal from the transmit antenna is changed (and the NCC-1 null can be very sharp indeed). But for me the benefits have far outweighed the costs.

The ferrite cores are a dull gray. The more common ferrite cores are type 43 Mix, but could also be a 61 mix. The 61 mix is a lighter shade of grey than the 43 mix. For reference, the tiny cores used for winding the KSB2 RFC1 and RFC2 are FT25-43. The FT designates a ferrite material, The "25" or "37" (or any other number) is the outer diameter in inches x 100 - i.e .25 inch diameter is 25. The number after the dash is the ferrite mixture type. I hope that helps. 73, Don W3FPR On 3/26/2015 11:15 PM, Brian Denley wrote: > Ken and Don: > I am interested in this as well.

Will the KX3 features: - CWT mode enables FINE tuning - SPOT with RIT enabled tunes RIT, not VFO A be ported to the K3? I liked these features at my KX3 a lot. And I think implementing these features at the K3 will be a great improvement as well. Scenario -------- You are calling CQ and the answering station is not at your tx frequency. KX3: ---- Tip spot and your rx-rit moves to the calling station. (your tx frequency will not change) K3: --- Tip spot and VFO-A (and so your TX frequency) moves to the calling station. May be the calling station wonders why you are vanished. As spot is good but sometimes can not be perfect, in my opinion it will be a good idea to auto switch on FINE tuning then. I wonder that after a such a long time the K3 exists noone else but John (KN5L) and now I missed these features.

In-Reply-To: References: , Message-ID: Thanks, Bob, for your concise description of how you use your NCC-1 with your K3---it is very helpful to me as I am almost confused by all the choices of configuration---a lot more ways to set it up than I thought. My situation is that I plan (at least initially) to use only 1 un-amplified noise antenna into the B input of the NCC-1 along with a DXE Receiver Guard (high RF limiter to protect both rig and NCC-1 during xmit) since my transmit antenna is a mere 20 feet or so from my operating desk. I'll see how that works and then add a second noise/receive antenna to the A input. Both noise antennas will be simple vertical wires or short indoor dipoles here in our small rented condo; maybe one will be longer and bent around corners and windows out to the back balcony. I can't really put the noise antennas outside the shack as our windows and back balcony are screened in with fiberglass in a frame that the owner installed that I would be very reluctant to mess with. At least my xmit antenna is outdoors and a bit higher up. While I am on a multiband inverted U dipole now I am almost finished building a really fine magnetic loop as mentioned in my earlier post; it will probably be an improvement over the inv. U to start with and its high Q will undoubtedly help with the RFI hash before I put the NCC-1 to work, too (fingers crossed). Ultimately I will also employ a second and third STL (mag loop) as noise/receive antennas for diversity reception and better noise nulling once I am able to put them in place. But that may a lot more tricky than I imagine if I will have to constantly re-tune them as well as the main transmitting loop---so we'll see how it goes with the simpler vertical wires first. I got the big box from DXE yesterday and lo and behold, the NCC-1 is almost the same size and heft as my loaded K3/100! I still need to make up some RG58 jumpers so I can hook it all up but I will try to do so tomorrow during the WPX (been delayed with other stuff all week so am not ready to get it up and running just yet). I want to make sure I hook it up correctly and your reply has certainly given me a clearer picture of how to accomplish that now. Since my noise antenna(s) will not be active I will set the internal dip switch to external power for the noise antennas and keep power from being applied to that port completely. Also, since I run QRO most of the time (and my STL will be set up to handle 650 watts from my KPA) I will make sure that the TX control line is plugged into the K3's PTT jack and that the BNC receiver Guard is correctly placed ahead of both the NCC-1 and K3 RX input. I considered spring for one of DXE's sequencers but as I am already over budget on this shebang I decided to go with the less expensive Receiver Guard initially. Hopefully this will suffice with no further gear inline required---but if anyone here thinks that is still unwise please speak up ASAP* as I want to try to get this going sometime Saturday during the WPX---I'll need it with the current noise on most of the bands here. (*If I AM running the risk of damaging my receiver/NCC I will not use it at all during QRO operation until I can eventually get a sequencer in line, too) Fingers crossed and hoping that I will be OK with what I have now so I can start enjoying this fine piece of gear right away. Thank you again, Bob for helping me out; it is very much appreciated. I can't wait to watch the noise diminish on my P3, too.

My problem included no receive. The upshot was that the KX3 had been dropped and the antenna BNC connector had been pushed in just a little. The clearances are quite tight there, and the antenna BNC was shorted. I bent the case back into shape, removed the antenna connector, and fixed the short. Everything works again. BTW, the schematic doesn't show the antenna low pass filter. I had to look at the circuit board to be sure that when I was reading zero ohms resistance across the antenna jack, I was not reading an inductor. With the jack disconnected from the board, the resistance should be infinity, or at least very high. (When it is connected to the board, the resistance is very low.) 73 Bill AE6JV On 3/27/15 at 11:25 AM, elecraft at mailman.qth.net (George via Elecraft) wrote: >No longer matches any antenna.

Message-ID: I have two dummy loads that might be useful for the 50-watt TX-gain calibration but neither of them are dead on with a 1:1 SWR and 50 ohms resistive load. Actually, my smaller 150 watt dummy load is closest with a range of 42 ohms on the load to about 55 ohms on the high end as I step through the frequency ranges of my Antenna analyzer. My 1500-watt dummy load is worse as the resistance goes up to 87 ohms Z (resistive plus reactive) with 54 MHz test signal (using MFJ 259 analyzer). My little Elecraft DL-1 20-watt dummy load (mini-module kit) is best as it is flat 50-ohms resistive across the entire HF spectrum. I am thinking of using and following the advice of Wayne to let it cool down between bands. But? If I want to let the dummy load cool down between bands then can this be done using the automated procedure with the K3 utility or do I have to run the manual procedure. In other words, does the automated procedure allow me to automate the process on a band by band basis. I have not tried it yet because I didn?t want to start something until I was ready to finish it (and I have not installed the latest firmware yet). Question: How accurate should the dummy load be ? is an SWR of 1.2:1 and under good enough? Question: Does the K3 Utility allow me to perform the TX gain calibration on a band by band basis?

But it has a fan, and when there is nothing going on in the shack, the fan is audible. So I got a temp control gadget on eBay for 15 bucks shipped from the U.S. I opened up the power supply. I opened up the supply, cut the hot lead to the fan and brought out a little twisted pair to an R/C connector so I could control the fan with the temp gizmo. I stuck the sensor next to one of the power transistors with some picture-mounting gum. Now all is quiet until I transmit. Then it kicks on and stays on (you can set both in and out temperatures), so everything stays nice and cool as well as nice and quiet. If you're looking for a good power source for your K3, I recommend the Pyramid, and I also recommend this simple mod.

In-Reply-To: References: Message-ID: <55173E14.7040306@embarqmail.com> Phil and all, There are two types of dummy loads - one is simply to provide a load to your transceiver or amplifier for a quick sanity check that the transceiver or amp is providing output and is capable of transmitting a signal. The other type of dummy load is one used for calibration and/or measurement of the output power. The first type does not have to be exactly 50 ohms non-reactive - it is only to protect the transceiver or amplifier, but the 2nd type needs to have a real 50 ohm non-reactive impedance if the results of the calibration or measurement is to be valid. So it all depends on what you are using it for and the accuracy of the results you expect. In other words, the dummy load that I switch my transceiver to when the antennas are not in use does not need to be accurate, but the dummy load that I use for the K3 TX gain calibration does need to the 50 ohms non-reactive over the frequency range that is to be calibrated (1.8kHz to 54MHz). In the past, I have mentioned several ways of obtaining good and accurate 50 ohm non-reactive dummy loads. Those range from the 75 watt dummy load available from Ridge Equipment, to those VHF/UHF dummy loads available at hamfests. Add to that good dummy loads that can be homebrewed - Caddock 50 ohm thick film resistors mounted on an adequate heatsink, or several other sources for homebrew dummy loads in a quart can filled with mineral oil. Yes, the accuracy of the 50 ohm non-reactive load will affect your results - get a good one if you want good results. The K3Utility is an automated process which proceeds from band to band automatically. There is no way to pause it to allow the dummy load to cool down. If you want to use a dummy load of lesser wattage than the required transmitter output (50 watts), then you will have to do the TX gain Calibration manually from the K3 menu. 73, Don W3FPR On 3/27/2015 8:27 PM, Phil Hystad wrote: > I have two dummy loads that might be useful for the 50-watt TX-gain calibration but neither of them are dead on with a 1:1 SWR and 50 ohms resistive load.

In-Reply-To: <55173E14.7040306@embarqmail.com> References: <55173E14.7040306@embarqmail.com> Message-ID: Phil, Your 20-watt dummy load will work with the automated procedure, and it is the best one because if the SWR is over some threshold you'll get a "SWR too high, calibration failed" message. The 20-watt load is very unlikely to overheat; my 10-watt load did not overheat, because the 50-watt transmissions are short. However, the sure way to make it work is to cool it with a sandwich bag filled with crushed ice. The automated version only takes a minute or so to do and it only has to be done once. If you are unsure, you can follow Wayne's advice and do it manually, allowing some time to cool in between each band. 73, Tony KT0NY From jameskvochick at me.com Sat Mar 28 20:31:49 2015 From: jameskvochick at me.com (James kvochick) Date: Sat, 28 Mar 2015 20:31:49 -0400 Subject: [Elecraft] ESTATE SALE: K2 with options & KPA100 +KAT100 in EC2 Enclosure Message-ID: <81719AD2-5129-4269-975B-B43816B08B06@me.com> Estate radio for sale: K2 Transceiver (serial number in 58xx range) Transceiver includes: KSB2 SSB Module K160RX 160 Module KNB2 Noise Blanker KAF2 Audio Filter KAT2 20 Watt Tuner KIO2 Serial Port Kenwood Microphone Rework Modules KPA100 & KAT100 (100 Watt Amplifier and 100 Watt Tuner) Built in an EC2 enclosure (includes serial cable to connect to K2 All manuals I?ve had the station on the air, and despite the frequency display being a little off (probably needs an alignment) everything seems to work great.

(b) Continuation and extension of the amateur's proven ability to contribute to the _advancement of the radio art._ (c) Encouragement and improvement of the amateur service through rules which provide for advancing skills in both the communication and _technical phases of the art._ (d) Expansion of the existing reservoir within the amateur radio service of trained operators, _technicians, and electronics experts.__ _ How does all of this fit with having a failure and rather than troubleshooting that failure first and possibly fixing it simply (i.e a cold solder joint), boxing up the radio and shipping it off to the factory for repair, so as to "avoid further damage?" At the rate this hobby is going downhill I can envision the day when radios are returned to the factory to get a blown fuse changed.

At 150 MHz, the impedance is 50 + j2, which is pretty good for metal oxide resistors. At HF, I can't measure any reactance but that's probably due to the SWR meter. The load is convection cooled (flow-through).

I recently uncovered a bad solder on C41 that had been there from my initial build some years ago. Now I get 4.1w on 40m and 2.7w on 20m--both much higher than I've ever seen. I'd like to get more power out on 20m even if it takes away from 40m. L2 is wound pretty tight so there isn't much movement in spreading the windings. In searching the mail list for ideas, it does seem as if 20m should be closer to 40m. Should I rewind L2 loosely so it is easier to move around? Or leave it alone? And, yes, I've checked the number of turns on L1 and L2 as well as the capacitor values multiple times. These measurements are with the ATU out of the circuit.

The hummingbirds, at least the first species, have returned and are busily eating bugs. More flowers are opening for them also. The weather has been unpredictable but no weatherman does very well around here. It is wet and cool in the winter and dry and less cool in the summer; that is accurate enough. Propagation has gradually improved over the week to where on Friday it was almost back to good. The solar wind has slowed but its effects have left the ionosphere in pretty good shape.

So, do whatever you need to to accomplish that. Actually, you do not have to adjust all the turns, just move the end turns closer together or further apart. Yes, you should be able to achieve a bit more power on 20 meters, but remember that the KX1 LPF is a compromise - play with the toroids a bit to see what you can accomplish. Actually, you may be better off rewinding L2 on a new core (assuming you have one). I have found that some of those yellow cores vary in permeability, and if the one you have installed has a greater permeability than normal, the cutoff frequency of the LPF may be too low and shunt some of the 20 meter RF energy to ground. 73, Don W3FPR On 3/29/2015 1:55 PM, engineercm wrote: > Hi, all. > > I recently uncovered a bad solder on C41 that had been there from my initial > build some years ago.

Last week I bought the PX3 for my KX3. The PX3 required a much later firmware installed in the KX3 than was in it (I had not kept it current; if it ain't broke, don't fix it mentality). So, I downloaded the current KX3 utility, got the latest firmware and started the process to load the new files to the KX3. Nothing. Couldn't get the Windows laptop pc running Vista to talk to the KX3. I have three KXUSB cables. Tried them all. Nothing. Went back to the Elecraft website and downloaded the FTDI chipset driver. Still nothing. This is the same computer I have been using all along with all of my Elecraft equipment and it worked last time I tried. Contacted tech support at Elecraft, followed all their suggestions and still no joy. So........ since the laptop was getting a few years on it and lacked many of the modern features (no touch screen, etc) I went to my local big box electronics store and bought the least expensive laptop (out the door for a little over $300) they had running the most up-to-date Windows operating system. Installed the utility and files on it then uploaded the new firmware to the KX3 first try. I had needed a new laptop anyway that was dedicated to the ham shack so I solved two problems with one purchase. Maybe you have a friend willing to let you try his computer? Or maybe you are in need of a new laptop? I sure like the PX3!

I set up a JT65 macro to switch antennas and change my power down to 20 watts as well as put the K3 into DATA mode. I have a second macro to switch back to regular CW mode, other the antenna and 100 watts. I also have the PWR SET to PER-BAND so as not to overdrive my KPA500 (typically it needs 20-25 watts). The PWR SET has two sets of PER-BAND power levels, one for barefoot level (100 watts in my case) and one for the KPA500 (20-25 watts). Works perfect (yes, I am using the cable between the K3 and KPA500), except when switching back from JT65/JT9 mode. BOTH power levels on that particular band get reset to 100 watts. More than once I panicked when I had red lights and the OVERDRIVE message. But, thank you Elecraft for building very good protection into the KPA500, so no ill effects other than my heart rate raising too quickly. The easy solution is to set power control on switching back to CW mode to a much lower power, say 20 watts. And I have done that. But my question is: is there another way to do what I am doing without resetting the 2 per-band power levels? Thanks.. Jim Leder ...

In-Reply-To: References: Message-ID: <5519819B.8040609@embarqmail.com> Frank, The problem has to do with the light conductivity of the LCD diffuser. It is possible that one of the thin plastic sheets on the diffuser that should not have been removed was actually removed during assembly. The only correction is to replace the diffuser. Unfortunately, it is below the LCD and inside its pins. While removing the LCD with its many pins may be possible, it is not practical. If you want to change the diffuser, you will have to remove the LCD. The best (safest) method is to cut the LCD pins near the LCD body and remove the pins one at a time. Then remove the diffuser. Replace both the diffuser and the LCD. If that is too much pain, you will have to live with it as-is. 73, Don W3FPR On 3/30/2015 12:05 PM, Frank Krozel wrote: > Folks, I have two of these one is S/N 906 and the other one is 57xx. > The light on 906 is bright on both ends and the 57xx is about the same level across the display. > Without tearing apart both? anyone know what I can change on 906 to make it the same level of brightness across the panel? > > From wb5jnc at centurytel.net Mon Mar 30 13:05:15 2015 From: wb5jnc at centurytel.net (Al Gulseth) Date: Mon, 30 Mar 2015 12:05:15 -0500 Subject: [Elecraft] K3 firmware update failure In-Reply-To: References: <09613181-7D1B-4DBA-9928-AC8B9BE6AA69@charter.net> Message-ID: <201503301205.15560.wb5jnc@centurytel.net> The first cardinal rule when a peripheral or device quits working under a Windows OS: check/reinstall the driver and look for anything that might have changed in software. I cringe at the number of modems, sound cards, etc. which have been thrown in the trash by people who didn't understand the process. "My [insert device here] quit working. I went to Best Buy etc. and bought a new one. It works so the old one must have been bad." By installing the new device a new device driver was installed DUUHHH!! There is a good chance the driver or something in the OS was corrupted or incompatable, rendering the original device useless. (The classic related to this was a few years ago when some users reported receiving blue screens after a windows update was released. Investigation proved it to be an incompatability of the update with a certain piece of -- malware!) 73, Al On Mon March 30 2015 11:01:53 am Tony Estep wrote: > On Mon, Mar 30, 2015 at 8:02 AM, GDR wrote: > > ...This is the same computer I have been using all along with all of my > > Elecraft equipment and it worked last time,,, > > ======================== > I had a Windows 7 laptop that ran my station perfectly for years.

It sounds like you've gotthat much at least partially configured. I'm assuming you have HRD 6.2.9.354 (which I have) or later. Does the HRD Rig Control come up properly, and does it"follow" your VFO when you turn the main knob on your K3? On DM780, go into "Program Options" -> "Soundcard" anddouble-check that it's looking at the audio device you thinkit should be looking at. (I use a SignaLink USB, so it showsup as "USB Audio Codec"; YMMV, and yes, I know better, but...). Also under "Program Options", you might want to investigate"Soundcard Calibration". I'm not convinced that that alonewould fix your problem, but it might give you a better idea asto which tree to bark up next. On the main DM780 window, click on "Soundcard", which shouldbring up a couple of vertically oriented bar graphs - see ifthe receive one is behaving appropriately; you may need toadjust an input level on your Tascam or other device if it'sin "Overload" or barely bumping the "thermometer". BTW, thereare some helpful tips in the info area in the lower right-handcorner of the "Soundcard" window. You might also need to go into the OS X settings to double-checkthat it isn't (also) trying to grab the Tascam and/or the K3's serial line,even if VMWare and Windows think they own them. I haven't looked at the HRD forum lately, but you might take a lookover there just in case someone with this particular configurationhas encountered this problem before.

There's an oxymoron ;) If you have PSK31 working, you can do AFSK RTTY with the same hardware configuration, but use the "AFSK A" sub-mode, instead of "DATA A". If you want to do FSK instead ("FSK D" sub-mode), you'll need a hardware interface of some sort (could be as simple as a couple of transistors and resistors to level-convert between a RS232 port and the K3's PTT and FSK inputs. Whether or not FSK is better than AFSK is somewhat of a religious debate...... 73, ~iain / N6ML On Mon, Mar 30, 2015 at 11:56 AM, Joe Moffatt wrote: > I think I actually misworded things. > > I have N1MM and use it for CW all the time. > > I have the audio cables, and everything works fine for AFSK PSK31. > > I just have little experience recently with RTTY, and I just want to set it up correctly. > > Joe > > > > From: Gordon LaPoint [mailto:gordon.lapoint at gmail.com] > Sent: Monday, March 30, 2015 1:51 PM > To: Joe Moffatt; 'Elecraft Reflector' > Subject: Re: [Elecraft] RTTY K3 Help > > On 03/30/2015 02:42 PM, Joe Moffatt wrote: >> Apparently I haven't fooled with RTTY of any seriousness in years, but I am starting to get interested in DX chasing with it. >> >> So, how do you guys recommend setting up the K3.

N1MM will also use the MMTTY engine for you in a contest or when calling DX in a pileup. Download MMTTY to someplace on your computer, and then in the N1MM setup, tell it where to find MMTTY. Then, in N1MM when you open the digital interface window, the MMTTY window will also come up. MMTTY is a tad complex and obscure, but the good news is that it works well right out of the box, so you can ignore most of the options. Never understood the infatuation with direct FSK, but to each his own. For RTTY, select AFSK-A. You can select audio frequency with the K3 PITCH control, there are 4 choices I believe, mine is at 915 Hz [lowest]. Be sure MMTTY is also set at 915. Recent firmware editions include a filter in AFSK-A which really narrows your signal. AFSK-A is LSB. Put the K3 in TX TEST, go to transmit, and adjust the MIC GAIN for 4 solid bars ALC with the 5th flickering. Then go to TX NORM and set the desired power. You can't control the power on a K3 with the MIC GAIN. You won't find many casual QSO's on RTTY. "AFSK PSK31" is actually redundant. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/30/2015 11:56 AM, Joe Moffatt wrote: > I think I actually misworded things. > > I have N1MM and use it for CW all the time. > > I have the audio cables, and everything works fine for AFSK PSK31. > > I just have little experience recently with RTTY, and I just want to > set it up correctly. > > On 03/30/2015 02:42 PM, Joe Moffatt wrote: >> Apparently I haven't fooled with RTTY of any seriousness in years, >> but I am starting to get interested in DX chasing with it. >> >> So, how do you guys recommend setting up the K3.

Are their any plans to do this? Doubt it ... especially considering that the non-mini K3/0 is no longer available. You probably could sell your K3/0 and buy a K3 kit to build (and not be left with useless PCBs).

Through more testing, it appears it's not DM-780 problem at all, but more likely a bug in the VMWare USB stack. I can get PC sounds to play through the device, but as soon as I change anything at all, the sounds stop working and nothing I can do except unplug and replug the device (virtually, using the VMWare Fusion Disconnect/Connect menu items) will make it work again.

In-Reply-To: References: Message-ID: Yes, you are. Dummy loads are not fun, like nice radios. When I built a Heathkit HW100, 45 years ago, I needed a dummy load to align the transmitter section. Not having one, and having just spent all my discretionary funds on the radio, I used a pencil lead to make a resistor element. I had to experiment with different drafting pencils to find the correct resistance. I carefully removed the wood with a razor blade, and attached clip leads at the points that gave me 50 ohms. I dunked the result in a container of motor oil (probably not the best choice), and finished the alignment. It worked well and was a one shot deal. Later, following instructions in a ham radio magazine, I built a dummy load using two copper disks and 10 resistors. This was also installed in a quart can filled with oil of some kind. I put the dummy load under my shack and ran coax up to my rigs. Also worked well. Now, I use an Elecraft 20 watt load, and have used it for short periods of time at higher power to make quick measurements. This included the alignment work on my K3/100. 73, Rick Dettinger K7MW On Mar 30, 2015, at 2:43 PM, Dave Baxter wrote: > I often wonder about people who will buy expensive (but excellent) radio's, > then baulk at spending a few bucks, quid's or ?, on basic test kit like a > half decent dummy load! > > Am I missing something? > > Dave G0WBX.

Ask any boat owner. There is a reason why they call boats holes in the water you pour money into. Same thing for planes at engine overhall time. The problem is that connectors and coax and dummy loads are the sorts of things that can cause things to grind to a halt if they fail, or are not of good quality. A dummy load or SWR bridge that's out of spec can cause us to make bad decisions about matching in our system, or to mis-calibrate it. El-cheapo coax (or coax that's been wet inside) and junk connectors (and connectors that are badly installed) all cause failures that can cost big bucks. And all of these problems can be VERY hard to find. I recently spent more than $1,200 finding and fixing a problem with my SteppIR that turned out to be a piece of coax (good stuff) that got stepped on near a connector (good connector).

Unfortunately, it comes down to whether the product would have sufficient appeal to justify the R&D costs. Well, I tried! 73 de Jim - AD6CW On 3/30/2015 5:30 PM, Milverton M.

Interesting how some can build an entirely wrong building out of wrong assumptions. I have a 300w and a 1500w dry dummy loads and a Cantenna that all work just fine but just thought this 100w one would be fun to build and the price is right. Can't have too many toys. I have two complete VHF go kits each with digital capability and an HF go kit as well all with separate components from my base station. We sometimes have exercises and use dummy loads instead of antennas in tabletop training so can use a couple of extra dummy loads at times. Works very well with one in the go kits as well as one at the base. 73, Jim KG0KP From mcduffie at ag0n.net Mon Mar 30 21:43:21 2015 From: mcduffie at ag0n.net (mcduffie at ag0n.net) Date: Mon, 30 Mar 2015 19:43:21 -0600 Subject: [Elecraft] 50 Ohm Load - source?

I've recently started dabbling with FSQCall and have some issues optimising the KX3's filter for reception in this mode. FSQCall's waterfall shows the received audio spectrum between roughly 50Hz and 1630Hz, it's modem has a waveform bandwidth of 300Hz with a nominal centre frequency of about 1150Hz. I'd like to set my rx filter passband with a centre of about 1150Hz and a bandwidth of about 500Hz, but this can't be easily achieved. The best I can do is to set the filter fc at 1.28kHz, the bandwidth to 0.65kHz and block some more at the top end of the desired passband by activating the notch filter (which is quite broad) set to 1520Hz. Is there any good reason that the range of usable filter centre frequencies in DATA-A mode is limited from 1.28 to 1.72kHz? A larger range would be much more useful.

Message-ID: I have built, installed and tested a keying circuit and followed the instructions to interface the KXPA100 with the "Basic Operation with any Transceiver". My KX3 requires PA Mode to be On allowing all antenna matching to be done by the KXPA100. With the K2 and its KAT2 ATU, I cannot identify how to bypass the ATU and allow the KXPA100's ATU to do the antenna matching. I have previously adjusted the KXPA100's ALC to accommodate an FT817. Or, use J4 Ant on the RF Board as the interface to the KXPA100. The relays in the K2 will click and have no effect on the matching to the KXPA100. In this configuration, a 1.5 Watt unattenuated by the 3db KXPA100 Switch, shows a power output of 60 Watts on all KXPA100 modes.

We are seeing the K4 as every improvement comes along to our already excellent radio. Think about all the advancements since you got your K3 (OK, since I got mine sn 14xx). Remember those that were prompted by users like the expansion of the macro buffer among others. How many other companies would do that? ZERO. Your radio continues to just get better. I, for one, am glad they are doing it as they are instead of saving all the improvements for a new radio that I would have to buy to get them.

Part of the reason that we keep seeing these kinds of "Where's the K4" posts is that people are conditioned by the "big 3" to expect a "new" rig every year or two to get the latest and greatest features and performance. Eric and Wayne give us Elecrafters an ongoing stream of upgrades and let us chose what we need based on how we operate. This is why I rarely look at new rigs any more at Dayton. I'm not going to buy into the IC756/IC765Pro/ProII/ProIII upgrade path any longer. There is no K3/K3Pro/K3ProII. There is just the continual improvement of a terrific rig. I'm not going to spend $5100 on the FTDX5000/D/MP/LT just to have to buy the FTDX5100/D/MP/LT in a year at $5700 to get the upgraded performance. My K3 is constantly upgraded at a reasonalbe cost, and I can decide whether or not I want or need the upgrade. It's not Elecrafters who are drinking the "Kool Aide," it's those people who EXPECT to have to spend more money every couple of years to get performance upgrades who are guzzling Kool Aide day and night. Stop asking for the K4. You've already got it. 73, Scott, N9AA On 3/31/15 11:11 PM, Jim Miller wrote: > Exactly, I had my response written then erased it.

Well that seals it, it's the new P3 transmit monitor function we'll be seeing soon... :) 73, Scott, N9AA On 3/31/15 11:08 PM, Wayne Burdick wrote: > We don't comment on prospective product ideas.
