At first I assumed it was just overload as I was using a 160 meter dipole and the signal strength meter was maxed: however moving to steppir antenna tuned to 40 meters gave the same result with and smeter reading of only S9. I have a local AM station on 1450 KHz that produces a -10 dBm into a spectrum analyzer and -30 dBm on the P3. I had assumed from this, without making any further checks, that the receiver was just overloaded. The cracking sound does not sound like any dynamic range problem I have heard before but I have not taken the time to make any serious tests. I make these comments because I am not convinced this is any form of overload and wonder if it could be related to your problem. 73 Brian KF6C.

The AGC in the K3 can be customized (see my website www.w3fpr.com). "supposed to work better with AGC off" sounds like a generalized statement. If there is an extra strong signal in the passband of the receiver, having AGC on will reduce the strength of all signals within the passband, but with the K3, all it takes is a turn of the width and shift knobs to isolate the desired signal so that reduction in gain due to the strong signal is no longer a problem. There is no need to have a full width waterfall when tuning to a specific signal. 73, Don W3FPR On 12/1/2015 9:33 AM, Peter Pauly wrote: > What about digital modes?

The radio has KFL3B-FM, KFL3A-6K, KFL3A-2.8K, KFL3A-400, and KBPF3A installed. Injection of a 50uV signal (50 ohms) (-73dBm) at 7.05 MHz produces an S9 reading and the P3 indicates about -76 dBm. It falls to about S8 with 50 Hz bandwidth setting. (I have not performed any filter calibration) Injection of a 50uV signal at 1.4 MHz produces an S8 reading and the P3 indicates about -83 dBm.. A local broadcast station on 1450 kHz produces -10dBm into 50 ohms from my antenna, as measured with a calibrated Anritsu MS2034A spectrum analyzer. Applying this signal to the K3s thru an attenuator indicates the signal is about 70 dB over S9. Removing all attenuation results in good audio but with some crackling. The carrier display on the P3 is not stable under these conditions. Tuning down to 640 KHz KFI produces a -20dBm signal into the K3. Listening to KFI under these conditions produces clicks at times but the audio is generally very good. This may not be anything to do with crackling noticed by others but better documents the problem I had. 73 Brian KF6C.

Provided the K3/K3S has a suitable selection of narrowed roofing filters available. If one has only the single default 2.7 or 2.8 KHz filter, it may not be possible to remove the strong interfering signal from the *input* to the ADC resulting in hardware AGC action and/or ADC overload which *can* create the crackling described. 73, ...

Regardless of what mode I'm using, I set the ATTEN and PRE for conditions on the bands where I'm operating. On the higher bands, ATTEN is off and one of the two PRE settings will be on (I have the new KXVB3 installed in my vintage K3). For 30M and below, PRE is usually off. On 80 and 160, ATTEN us usually on. 73, Jim K9YC From Rodenkirch_LLC at msn.com Tue Dec 1 12:02:29 2015 From: Rodenkirch_LLC at msn.com (James Rodenkirch) Date: Tue, 1 Dec 2015 17:02:29 +0000 Subject: [Elecraft] How to make the KX3 controlled by logging Message-ID: Tnx to all that replied - and, now, I can control the KX3 with N1MM ....

It could also be a poor connection somewhere in the antenna circuit. Sometimes a coax plug or socket is oxidized (or whatever) and it has high resistance for small voltages such as received signals; a shot of RF cleans it up. I had a problem like this which drove me nuts for months. It turned out to be a corroded solder joint in a balun (at the antenna feedpoint, of course). 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 1 Dec 2015 19:06, KY7M wrote: > Towards the end of CQWW CW, I was having issues with the K3 not getting back > to receive when I stopped transmitting.

It uses PIN diodes, which are just peachy fine at 100 watt power levels. Amplifiers are another separate problem. QSK is a strain on any amplifier running 1500 watts. This is because affordable PIN diodes for the usual circumstances sort of disappear beyond 500 watts or so. Ask anyone that has owned an Alpha 89, which came out with PIN diodes for T/R switching. They never did that again. The pin diodes will hold as long as you NEVER, EVER do anything like transmit into an open or very high SWR. One of the most common QSK caused problems in amplifiers is insufficient delay setting in the transceiver (ANY brand or model) to allow amplifier's t/r relays to close AND settle before RF is applied to the amplifier. This is sometimes called "hot-switching". The outcome of hot-switching is burned contacts at minimum producing the problem you describe and others. At worst if allowed to continue, this can produce burned a burned bandswitch with irreparable damage, ruined transmitting capacitors, arc paths in various places, or damaged internal coax runs. For certain kinds of transmitting tubes, the tubes can be damaged by non-engineered states present during an arc-fault. Many amplifiers will NOT t/r switch and settle in the K3's 8 ms minimum delay, and some require MORE delay than advertised. There are aftermarket t/r boards which drive vacuum relays such as Jennings RJ-1A to quicker closures by a very short burst of higher than normal actuation voltage. These produce measured switch delays in the 2-5 ms range. But hard QSK use does wear down the vacuum relay after a while and they need to be routinely replaced to avoid issues. BEFORE you tear apart your K3 or send it back to Big E, PROVE beyond a shadow of a doubt that it is NOT the t/r relay circuitry in your 87A. The FIRST reason to do this is to make sure that the inevitable amplifier damage caused by a bad relay in the 87 is headed off. If the relay is not contacting properly at times, TAKE THE AMP OUT OF SERVICE and get the relay fixed, or a quicker circuit installed. You could easily save your self a $1000 repair bill on the 87. The 87 will switch to transmit by grounding the relay jack. The next time that the receive goes weak, unplug the cable from the 87's relay jack. Then see if you can make the RX come back by repeatedly grounding the 87's relay jack while the K3 sits unkeyed in RX mode. If you can make the RX come back up that way, the problem is in the 87A, and it's time to take it out of service. This also is just another example of our strange predilection to always blame the K3 first, which after noting what actually was found, is most often just dead wrong. 73, and Good Luck Guy K2AV On Tuesday, December 1, 2015, KY7M wrote: > Towards the end of CQWW CW, I was having issues with the K3 not getting > back > to receive when I stopped transmitting.

Provided the K3/K3S has a suitable selection of narrowed roofing filters available. If one has only the single default 2.7 or 2.8 KHz filter, it may not be possible to remove the strong interfering signal from the *input* to the ADC resulting in hardware AGC action and/or ADC overload which *can* create the crackling described. 73, ...

If they are, then the RF gain becomes useful, otherwise I leave it alone. I recently tried turning the AGC off in DATA A mode. If you're trying to capture the entire audio bandwidth, it helps, a lot. A strong signal no longer swamps the weaker signals. This is for 'sweep' mode only, but I don't bother to switch it in for working DX. It follows my concept of never allowing AGC to kick in for the best data decoding (least is best). For low level signals, it seems to work better and is certainly worth a try. Then I narrow the filtering down to only the desired station per usual, clone the other VFO, offset split according to the DX instructions and make the contact. Pretty durned simple and easy. The only thing it's hard on is the ears, the sudden LOUDness of the band can be jolting when you switch to DATA A.

This has been done just because the owner is tired of the expense of the TX pin diodes, or living in circumstances that frequently present pin diode blow up events. Some folks I know had that mod done right away after they bought one used. Real QSK afficionados sometimes just deal with the diodes, which would put the problem somewhere other than the K3 and the amp, as in Vic's post. 86's, 87A's and 89's are legend for pin diode problems which is why so many have been converted to relays and need to be checked on intermittent RX problems just like any relay t/r amplifier. Such comments as this one in an eHam evaluation on an Alpha 86 are common: "I use the Alpha 86 for CW, RTTY contests and DXing. Since I had RF Concepts put in the vacuum relays, the reliability has been excellent." I know replacing the pin diodes is what I would do immediately on purchase of one of those. These days such things as W7RY's QSK boards for various amps make that relatively easy and result in an an outstanding amp for QSK. At some point I will have an SB-220, an AL1200, a homebrew 3-1000Z, and an HL-1K all modified with a W7RY board. 73, Guy.

Message-ID: Good afternoon, This past weekend when working the CW contest, I noticed something that may have a solution to it, but I don't know where to find it. I noticed that when I switched from one band using the KPA in Operate position to another band and then back to the original band again, the KPA500 reverts back to StandBy condition. It would be nice if the K3 would remember the state of the amplifier per band much like it does with the KAT500. Is there a parameter in the config/main menus that would allow me to set so that it would force the K3 to store the status of the KPA500 . If not, I have a suggestion for Wayne & Co.

But I would like to report some problems. This is with N1MM+ I interrupt a transmission with ESC. Periodically, I seem to hear completely different stations with CQ called on my run frequency. Before I was getting mad but now I know that K3 receives a different frequency than shown on the display. Pressing A=>B button fixes the situation. When running, accidentally pressing RIT or XIT causes K3 to get stuck in transmit. Switching off/on is the only solution. I am wondering whether most of the buttons can be make inactive in TX.

The KPA simply reads the BAND lines to determine the K3?s band. Your description sounds like you have the KPA500 menu setting BAND CHG set to STBY. If this isn?t the case, let me know.

I tuned one of them at 1.810 MHz and listened. The station identified as KGO, about 20 miles away with three beautiful towers at the edge of San Francisco bay. (Serious antenna envy here.) I then tuned to 810 KHz and indeed KGO was there as expected. I then used a band memory to switch back to the CW portion of 160 meters and the interference was gone. I think I have seen AM broadcast interference on 160M before, but I may be mistaken. Any ideas about what is going on? I have new synths and a new KBPF3A with the MF/LF mods. K3 is 6299. I did tune down below the BC band on November 14 when there were a lot of stations active down there, but the radio came up in the ham band when I switched with the band switch. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz | If you want total security, go to prison.

If you don't, ignore the rest of this post. But assuming you do, the sudden frequency appearance has nothing to do with the K3, all in MM logger. Check your setting in N1MM+ for: Config tab: Sub receiver always on. If you have "Sub rx always on" checked, if you have turned sub RX off and are listening to the main RX with both ears, in response to various events MM will turn the subRX back on at whatever frequency is on the "B" display. This will remove the main RX from your right ear substituting whatever is on the sub RX, which in a contest is just as likely to be CQ as anything. If you decide to go single RX at any point, remember to uncheck that config tab entry. Also there are keyboard shortcuts that when accidentally hit will cause issues. Have a look at http://n1mm.hamdocs.com/tiki-index.php?page=Key+Assignments+-+Keyboard+Shortcuts In particular look at Alt F12 in paragraph 3.5 In a lot of ways MM and the K3 have similar philosophical bents. MM is rich with options that well serve many people with preferences or special needs. The K3 does as well. This leaves the newby or the slow learner (like me) with the unenviable task of encountering these flexibilities without warning or understanding, all appearing as if the gods have gone mad in the radio. The reason it only took me six months to get used to my K3 was because it took me 2 years to get used to my K2, the two having some similarities in menu/operational philosophy. I've been using MM for six or seven years and I'm still getting used to it. I'm disadvantaged in this regard because I had TRLog imprinted on my neurons, which may never go away. Everything new anybody does to anything usually leaves me in the lurch wondering what is broke this time. Then I remember my own mantra ... It's almost never in the K3 ... and save myself a lot of grief by looking elsewhere. Totally empathize with your experience. You almost certainly will get used to it all faster than I did. 73, Guy K2AV > Am 01.12.2015 um 22:39 schrieb Ignacy: >> >> Generally K3 worked very well.

With N1MM the tilde key turns on the SUB RX. Now in my case this causes me to hear different stations in my right ear. But your K3 or your N1MM configuration may have a different reaction that is causing a frequency change. 73, Mike K2MK Ignacy wrote > Generally K3 worked very well.

I amy indeed use ` by chance although I have not done SO2V by choice. N1MM claims a bug in K3. This is in http://n1mm.hamdocs.com/tiki-index.php?page=Supported+Radios#K3_and_K3S: *The K3 contains a firmware bug that was reported several times and never been fixed which affects users who would like to use PTT via radio command. If the Esc key is pressed when a CW transmission begins and you are using PTT via radio command, the radio may not return to RX. The radio RX issue doesn't occur if the owner disconnects the CW jack from the rear of the K3 radio and doesn't change any N1MM Logger setting. Similar issues have been reported on other modes. Delay has been added to the N1MM Logger program when Esc is pressed but the problem still occurs intermittently. The problem seems to be worse with the very early K3 radios. Until this firmware issue is corrected, users may notice that the radio does not return to RX intermittently when using PTT via radio command. When this occurs, make another transmission and end it with the ESC key.* Ignacy, NO9E -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-N1MM-freq-jumps-etc-in-CQ-WW-CW-tp7611005p7611033.html Sent from the Elecraft mailing list archive at Nabble.com.

I'm also planning on purchasing the Powerwerks switching PS and the power supply cable for the PX3. Initially, I plan to use the system as a QRP CW/Phone (mostly CW) rig.

As far as I understand it, I'll need: *Main Items:* KX3 Kit PX3 Kit Power Supply for KX3 Powerpole terminated cable for above. Power Supply for PX3 *Connectors:* All of my antenna feed lines terminate with PL259 connectors. My research suggests that I'll need a BNC Male to SO239 adapter, as well as (for convenience) a right angle BNC-BNC connector. Is a right angle male BNC to SO239 connector available? That would be ideal. I'm waffling on the paddles, as I have 2 beautiful sets of brass K8RA P-4 and P-3 paddles to use in the shack. Probably a later purchase. I do have a question, however, regarding the charger. Will the internal charger charge LiPo batteries or only NiMH? Can LiPo batteries be used in the unit if charged with an external charger? I'll also need cabling to connect to my Windows 10/7 computer; I think this comes with the unit but thought I'd better check. Thanks for all of your advice and experience with the KX3! I'm excited!

For the shack, if you have some nice paddles already, I would suggest just using those. If you are operating portable, the KXPD3 paddles are light and convenient. Internal charger is for NiMH cells only. You can use an external LiPo battery, although I prefer LiFePO4 batteries myself (they are safer, and the voltage output from a 4S pack is ideal, whereas the output of a LiPo pack is likely to be too low or too high). You of course need an external balance charger designed to work with the specific battery chemistry you choose. If you plan to do phone, you?ll need a microphone. You can order one from Elecraft, or you can use a computer headset. The radio does not come with any cables (except a flying lead power cable and USB cable), so you should order a cableset if you want to connect the audio to a PC soundcard.

Only NiMH. > Can LiPo batteries be used in the unit if > charged with an external charger? No. AA batteries only. The consensus recommendation for internal batteries is Eneloop XX. Those are high-quality, high-capacity, low self-discharge batteries. You don?t need a right angle BNC unless you want to dress the cables that way. I don?t use one. I highly recommend the SideKX endplates and covers if you ever want to take the KX3 off your desk. High quality protection and a deal at $69. http://gemsproducts.com/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) From mhvnmn at gmail.com Wed Dec 2 12:38:26 2015 From: mhvnmn at gmail.com (Marc Veeneman) Date: Wed, 2 Dec 2015 12:38:26 -0500 Subject: [Elecraft] Ready to Purchase KX3 and PX3 - Would Like Advice on accessories and "must haves". In-Reply-To: References: Message-ID: Hi, Mark. I have 3 KX3s, 2 of them here in Grand Rapids and the 3rd in Vermont at our summer home. I used the KX3 for a single operator battery powered Field Day in 2014 on the deck in Vermont, so even have a bit of portable experience. I think I can answer all your questions, but first let me say you're getting probably the single nicest rig available. I do have a K3/P3 here on the desk next to my KX3/PX3/KXPA100 but rarely use the K3. Both my 80 meter dipole and the G5RV are hooked up to the KX3 system. I also have both the dual paddle and single paddle K8RA keys. They are larger and heavier than the rig! They're excellent keys and the single paddle is about as nice as they come. However they aren't style matches to the Elecraft gear so I usually use my 9A5N paddles instead. But what will you need? Start with right angle 3.5 mm stereo plugs. When you put the station together you'll find it's a mass of cables. The Mike, Key, and Earbud jacks are all on the side of the KX3 that abuts the PX3. They all deserve right angle plugs. I finally bought some right angle adapters so I could, when needed, use straight plugs. Get yourself a 3.5mm stereo Y cable so you can use both paddles without switching anything around. I do that with the single- and dual-lever paddles. When I was comparing paddles to see which kept me most mistake-free at higher speeds, I actually used serially connected Y cables and 3.5mm male to 6.5mm female adapters so I didn't have to rewire the paddles and keys I was testing. At one time I had 8 keys all active simultaneously into the single KX3 "key" jack. Yes, you'll need to convert BNC to SO239 and you'll want a right angle male-to-female BNC adapter -- again to keep things looking neat and keep cabling aimed away from you. If you get a KXPA100, it'll come with a right-angle BNC connector on a short cable with a PL259 on the other end. I'm sure you could buy just that from Elecraft and then use a dual SO239 to connect to your coax. So -- think right angle and you'll be set. The receiver on that KX3 is wonderful. You'll love it if you do much CW work. 73, -- Marc > On Dec 2, 2015, at 12:11 PM, Mark Tosiello wrote: > > Hi all!! > > > I'm preparing to purchase the KX3 and PX3 kits.

I bought them for mine and am glad that I did. It does a great job of protecting the rig. The only other thing you might look at is a good external speaker for use in the shack. I have used the West Mountain speakers ( http://www.rffun.com/catalog/speakers/5042.html) which don't have RFI issues and was pleased with them. I now use a pair of JBL near field monitors through a mixing board. Enjoy the new rig!

I've read your post and the replies and figure I maybe read what you said incorrectly, but you did say: Then use the TUNE button on the K2 to tune the loop to resonance, then operate. You can't use the K2's antenna tuner to tune a loop to resonance. That's not how they work. The loop is a complete tuned circuit in itself. There's the loop representing inductance and a capacitor in parallel with it. These are resonant at a frequency and the only practical way to move that resonant frequency is to adjust the value of the capacitor that's in parallel with the loop. You can't adjust that resonant frequency using an auto ATU at the end of a length of coax. It's rather like using a telephone conversation to make a physical change at the other end. You can't use the phone to make the beds back home, when you're away! The auto ATU will see the coax cable and the loop as a lump of L and C and will endeavour to match it to 50 ohms to get a 1:1 SWR. The coax forms part of the antenna and is not behaving like a transmission line and the loop is not behaving like a resonant circuit - you might just as well hook the coax to your automobile's fender and use the auto ATU to tune that! Please forgive my descriptions if I have misunderstood your question, but re-reading your quoted statement makes me feel like I'm the only one who has understood. Yes, by all means match the auto ATU into 50 ohms using a dummy load. That way, the PA is looking into a load that matches the impedance of the transmission line, although as Don suggested, you don't really need the auto ATU (and its losses) as the PA should be reasonably well matched by bypassing the auto ATU entirely. Now, at the loop end, there's a gamma match arrangement that ensures the loop, when at resonance, is a decent match to the 50 ohm transmission line you're using. So the rig matches to the transmission line which matches to the loop that's been tuned to resonance with its inbuilt tuning capacitor. A loop is only a single turn coil, the resonant frequency of which is varied by adjustment of its parallel capacitance. Because it's small and is a low loss inductor operating with a low loss airspaced (or vacuum) capacitor, the Q factor, or "goodness" of the single turn coil at resonance is very high. This means that a small excursion away from resonance, the loop's Q falls very rapidly and renders it pretty useless, thus it is necessary (more so when transmitting through the loop) to retune it for frequency shifts of more than a few kHz. That means that the SWR rises rapidly away from resonance and the coaxial cable is more involved in becoming part of the antenna and less of a transmission line. The outer surface of a loop (well, outer 6%) needs to be of very low resistance in order to maximise Q at resonance. RF skin effect uses only the outer surface of the conductor, thus the larger the surface area of the conductor, the more its internal resistance is in parallel and thus reduced, so the better performer the loop becomes. Even a soldered joint on copper piping offers resistance that compromises the loop's performance. Recently a friend gave an old army magnetic loop to a group of collectors/militia enthusiasts. It was in poor condition, but in its prime, its surface area must have been a foot across. This makes a mockery of the little bits of aluminium (aluminium) joined together with bolts and wing nuts. Yes, says the vendor, it is broad banded and only needs retuning every 100kHz or so. What he doesn't say is that its resistance makesthe Q so appalling that its performance is lousy (where lousy is the polite word), but those devices give properly engineered mag loops a bad name by tarring all with the same brush. Also, there are proportionally more crappy mag loops out there simply because they are cheaper than the "real" thing. The MFJ 1782/86/88 aren't too bad and are just at the crossing point between good and bad, with a bias towards the good, if not too many spiders and other insect life are resident under the black covers. These loops have an airspaced variable capacitor within the black covers and that capacitor is tuned by a small electric motor that's attached to it. DC power for the motor is fed down the coax cable itself, as well as the radio signals. They are not difficult to separate, eliminating the need for a control cable. The DC voltage on the coax is reversed in order to make the motor turn in the opposite direction. The more sophisticated MFJ controller has an inbuilt cross-needle SWR meter and the name of the game is to get the SWR as low as possible on the operating frequency. Their semi-automatic controller drives the motor and detects the lowest SWR point and stops. Of course, to detect the lowest point, it has to begin to increase again, so it always stops at a point that's not quite at resonance and this must be fine-tuned by the operator, hunting to and fro with up/down press-buttons. It takes more effort to describe than to do in real life Hi! One last caution. Circulating currents are very high in a transmitting mag loop and very high voltages (thousands of 'em) are also present when at resonance, so ensure that the loop can't be touched by anything that matters to you when it's transmitting, even at a few watts. Give it a LOT of respect, indeed, powerline respect. I hope my efforts haven't missed the mark by a mile, Brian and that instead, the wear and tear on my keyboard has been of some small use to you. 73 and early Season's Greetings.

The FAQ section addresses practically every scenario possible with the Elecraft products and Fred has invested notable effort in helping make sure you don't inadvertently purchase more of his publications than you really need. It cleared up my questions quickly.

For the KAT100 it is ATU CAL. The TUNE button will then simply put out a carrier (the KAT100 will not tune, but is effectively bypassed). With the KPA100, that power will be limited to 20 watts or if the Power Knob is set lower than 20 watts, it will put out a carrier at the set power. If it is significantly higher than that, the KPA100 wattmeter has a problem. 73, Don W3FPR On 12/2/2015 3:52 PM, Dave Lankshear wrote: > Hello, Brian. > > > > I've read your post and the replies and figure I maybe read what you said > incorrectly, but you did say: > > > > Then use the TUNE button on the K2 to tune the loop to resonance, then > operate. > > > > You can't use the K2's antenna tuner to tune a loop to resonance.

The "geeks" would have no problem with this proposal, but the casual user may run into difficulty. If the configuration data could be separated into general and K3 specific files, then your suggestion would be valid. I agree that posting the configuration of each K3 (K3S) would cause a huge increase in Customer Support calls and emails. The firmware load does not cost $500. It is more likely to amount to the minimum charge of $99 plus shipping. 73, Don W3FPR On 12/2/2015 7:43 PM, Kevin Stover wrote: > If I was Elecraft I'd run as far away as I could from this idea. > Elecraft would be responsible for fixing thoroughly screwed up radios > when junior firmware author blah blah posts his number 1 best K3(s) > configuration on the net. > > The configuration saved also includes calibration data for that > particular radio. > > On the other hand here is an opportunity for Elecraft to charge $500 > per radio for a firmware reload to default factory settings. > > On 12/1/2015 9:02 PM, Nr4c wrote: >> I think a lot of users would like to be able to save user settings so >> that several radios could be configured similarly.

If you want a mag loop to actually act like an antenna, it MUST be exactly resonant on your transmit frequency ... period. No antenna "tuners," which have never "tuned an antenna" anyway. Bypass the KAT2/KAT100 or whatever. Tune the mag loop cap to 1.0:1 ... not 1.5:1 or "close" ... 1.0:1. The K2 will tell you this. That's all you do. 100W into a small mag loop probably exceeds it's ratings by close to an order of magnitude, and please don't do it if I'm sitting next to it. :-) These are QRP field antennas. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/2/2015 1:14 PM, Don Wilhelm wrote: > Dave and all, > > You only have to put the tuner into Calibrate.

Overall everything works fine but there is a strange issue while configuring and getting to work the PTT port assignment. When I start the WSJT program, it will not key the K3s PTT unless I just start up and run another program like the K3 configuration tool. As soon as that starts up and shows the communications is good on port XX at 9600 baud. As soon as I close down the K3 config program, everything works fine with the WSJT software control of the PTT port. Other programs like WSJT-X have a newer interface and allow you to select the port and baud rate for radio control so 9600 works fine right off. What appears to be occurring is that the K3s USB com port which would normally be set at 38.4 for the config program is forcing the reset of the USB com port to 9600 to be compatible with the WSJT program. I have not been able to reset the baud rate for the K3s to be 38.4 as the default data rate using the Windows control panel.

I now have a K3s and it is running great along with the P3, KPA etc using the special CBLP3Y cable supplied for the P3. I have not yet tried to re wire the RRC box to the K3s but I am not sure if I should disconnect the PC end of that cable from the PC and plug on the P3 and connect it to the RRC com port, or remove the CBLP3Y cable from the K3s and install the RJ45-DE9s cable between the K3s and the RRC box? Since I am currently using the USB for my com port interface, I would assume that when using the RRC box, I would re configure the K3s for using the regular RS 232 port xxx baud? Has anyone on this list had experience with wiring up the K3s to the RRC remote unit?

Mark, your order is spot on and you?re going to love that setup, just as I do mine. As for speakers, let me recommend what I use. Formerly sold with the brand name Kinivo, my most recent purchase was called Satechi: http://www.amazon.com/gp/product/B007TOHOIQ They can be run for many hours on their internal lithium battery, can be separated so you hear split signals easily, and are ideal for CW. Their small size isn?t a negative when you want to hear sidetone at 440 as I do, or 600 or 700 as is more popular. They sound great and the price is, in my opinion, very low. The reason I bought a second pair is so I can run them on the K3 while the first set is connected to the KX3. My next pair will be stored in the Pelican case with my travel KX3. They are that good. Again, congratulations on your purchase. You learned one more thing today and that is the Elecraft order taking system. Those West Coast hams will steer you away from purchase mistakes and seem to have the customer?s satisfaction in view instead of Elecraft sales quotas. What a refreshing change! ?

Message-ID: <1449197142812-7611066.post@n2.nabble.com> Hello everyone on the reflector. I have recently really started enjoying CW again. I am relearning the code and have made some wonderful contacts. I was lucky enough to purchase a K8RA P5 Big Dog key from Jerry before his passed. It is 7 lbs of beautiful brass made in the USA key. I then wanted to own a straight key. So I purchased a Begali Blade Straight Key. When it came in I could not believe how big it was, but it was so smooth. I then learned of a first class key maker that made all of his straight keys by hand in his work shop. He makes these beautiful titanic keys and the quality is so impressive. He also makes a Ericsson Key which is a swiss pump style key. They looked awesome too. I spoke with this gentleman and he informed me he was going to make a new key and I could purchase serial number 1 from him. The key he as going to make was the Marconi PS 213 key. I agreed right off the bat to own this key. I researched it and they looked really nice. I received my key a day ago and all I can saw is wow. I could only stand there and be amazed with it. First thing that grabs you is its massive size, and then its beauty. I adjusted it to my sending style with is really no movement on the arm and it was sweet. Super smooth and really fine adjustments. I decided I needed to share this key with everyone on this reflector so I took a picture of it in front of my K3. I hope this photo shows up and I hope it does justice to how beautiful the key is and I know it will show its massive size. This Key was built by Mr. John Wellings from Birmingham England. He is truly a master craftsman.

Message-ID: Well after waiting almost 4 months it seems the US distributor that I ordered my 2k-fa amp from has gone qrt, permanently (Expert Amps USA). I chose them over the other US distributor because I though they looked more stable. Bad choice but it brought me to the realization of the dangers when dealing with '1 horse' companies. SPE in Italy appears to be the real deal but these two (now one) US distributors give me a less than warm & fuzzy. So as much as I really wanted the 2k-fa, I'm now in the market for an amp compatible with the k3s. What I want in an amp (or as much of it as I can get): 160-6 coverage Auto antenna tuner Auto operation when connected to the k3s so I can operate the rig remotely and only have to worry about monitoring the amp (it will automatically follow the transmitter, select the appropriate antenna and tune itself. Full legal limit + rated so I can operate with 'headroom' to spare. That's pretty much what the 2k-fa offered but I haven't been able to find a similar amp. The OM looks close. . . Any suggestions?

This was for a MFJ-1788 Magnetic Loop working with a KX3 and based on an Arduino micro-controller. I don't own the MFJ product but I do have an Alex Loop and with a few simple modifications the circuit should work nicely. The loop tuner uses a DC motor but I thought a stepper might be more elegant. Thus, I needed to determine the working bandwidth of the Alex Loop to get some idea of the angular resolution I needed from either a direct drive stepper, or a stepper using gearing. I looked at the Alex Loop around 7, 18 and 30MHz. 3:1 VSWR bandwidths were measured using a RigExpert AA-54 antenna analyzer. For 3:1 VSWR the measured operating bandwidths at these three frequencies were determined as 44, 65 and 190kHz respectively. Pretty narrow at the lowest frequency. Thus, to get a good chance of achieving a VSWR approaching minimum, I figured the angular motion should be fine enough at worst case (7MHz)to achieve an angular motion of the tuning capacitor of no more than 1/0th the 3:1 VSWR bandwith = approx. 4kHz. Since one and a half turns of the tuning capacitor tuned the Alex Loop from resonance at 7 through 30MHz (and assuming the frequency response is linear, which it is not) then the required angular resolution is 360 * 1.5 * 4 /(30000-7000) = 0.094 degrees. Since a typical stepper does 200 steps per revolution, then the required gearing ratio would be approximately 20:1. With this type of performance the magnetic loop could be very close to resonance at the chosen operating frequency presenting a VSWR approaching 1:1. 73's Gary K6YOA Message: 3 Date: Wed, 2 Dec 2015 20:52:18 -0000 From: "Dave Lankshear" To: Subject: [Elecraft] [K2] Tuning a magloop with KAT100 Message-ID: <7B2795A9D35B4139812BF284FD02542B at DaveLLaptop> Content-Type: text/plain; charset="us-ascii" Hello, Brian. I've read your post and the replies and figure I maybe read what you said incorrectly, but you did say: Then use the TUNE button on the K2 to tune the loop to resonance, then operate. You can't use the K2's antenna tuner to tune a loop to resonance. That's not how they work. The loop is a complete tuned circuit in itself. There's the loop representing inductance and a capacitor in parallel with it. These are resonant at a frequency and the only practical way to move that resonant frequency is to adjust the value of the capacitor that's in parallel with the loop. You can't adjust that resonant frequency using an auto ATU at the end of a length of coax. It's rather like using a telephone conversation to make a physical change at the other end. You can't use the phone to make the beds back home, when you're away! The auto ATU will see the coax cable and the loop as a lump of L and C and will endeavour to match it to 50 ohms to get a 1:1 SWR. The coax forms part of the antenna and is not behaving like a transmission line and the loop is not behaving like a resonant circuit - you might just as well hook the coax to your automobile's fender and use the auto ATU to tune that! Please forgive my descriptions if I have misunderstood your question, but re-reading your quoted statement makes me feel like I'm the only one who has understood. Yes, by all means match the auto ATU into 50 ohms using a dummy load. That way, the PA is looking into a load that matches the impedance of the transmission line, although as Don suggested, you don't really need the auto ATU (and its losses) as the PA should be reasonably well matched by bypassing the auto ATU entirely. Now, at the loop end, there's a gamma match arrangement that ensures the loop, when at resonance, is a decent match to the 50 ohm transmission line you're using. So the rig matches to the transmission line which matches to the loop that's been tuned to resonance with its inbuilt tuning capacitor. A loop is only a single turn coil, the resonant frequency of which is varied by adjustment of its parallel capacitance. Because it's small and is a low loss inductor operating with a low loss airspaced (or vacuum) capacitor, the Q factor, or "goodness" of the single turn coil at resonance is very high. This means that a small excursion away from resonance, the loop's Q falls very rapidly and renders it pretty useless, thus it is necessary (more so when transmitting through the loop) to retune it for frequency shifts of more than a few kHz. That means that the SWR rises rapidly away from resonance and the coaxial cable is more involved in becoming part of the antenna and less of a transmission line. The outer surface of a loop (well, outer 6%) needs to be of very low resistance in order to maximise Q at resonance. RF skin effect uses only the outer surface of the conductor, thus the larger the surface area of the conductor, the more its internal resistance is in parallel and thus reduced, so the better performer the loop becomes. Even a soldered joint on copper piping offers resistance that compromises the loop's performance. Recently a friend gave an old army magnetic loop to a group of collectors/militia enthusiasts. It was in poor condition, but in its prime, its surface area must have been a foot across. This makes a mockery of the little bits of aluminium (aluminium) joined together with bolts and wing nuts. Yes, says the vendor, it is broad banded and only needs retuning every 100kHz or so. What he doesn't say is that its resistance makesthe Q so appalling that its performance is lousy (where lousy is the polite word), but those devices give properly engineered mag loops a bad name by tarring all with the same brush. Also, there are proportionally more crappy mag loops out there simply because they are cheaper than the "real" thing. The MFJ 1782/86/88 aren't too bad and are just at the crossing point between good and bad, with a bias towards the good, if not too many spiders and other insect life are resident under the black covers. These loops have an airspaced variable capacitor within the black covers and that capacitor is tuned by a small electric motor that's attached to it. DC power for the motor is fed down the coax cable itself, as well as the radio signals. They are not difficult to separate, eliminating the need for a control cable. The DC voltage on the coax is reversed in order to make the motor turn in the opposite direction. The more sophisticated MFJ controller has an inbuilt cross-needle SWR meter and the name of the game is to get the SWR as low as possible on the operating frequency. Their semi-automatic controller drives the motor and detects the lowest SWR point and stops. Of course, to detect the lowest point, it has to begin to increase again, so it always stops at a point that's not quite at resonance and this must be fine-tuned by the operator, hunting to and fro with up/down press-buttons. It takes more effort to describe than to do in real life Hi! One last caution. Circulating currents are very high in a transmitting mag loop and very high voltages (thousands of 'em) are also present when at resonance, so ensure that the loop can't be touched by anything that matters to you when it's transmitting, even at a few watts. Give it a LOT of respect, indeed, powerline respect. I hope my efforts haven't missed the mark by a mile, Brian and that instead, the wear and tear on my keyboard has been of some small use to you. 73 and early Season's Greetings.

One solution is to activate QRQ mode (CONFIG CW QRQ = ON). There are some limitations, such as not being able to use it with SPLIT or RIT/XIT. The better solution is to buy the new synthesizer and replace it. In that case, if you have the second receiver, you need two synthesizers, which unfortunately will be expensive (especially in Europe). The K3S comes with the new synthesizer. I suggest you try sending with a paddle at the speed you want to use to determine if this is the cause. There is also a problem with any computer-generated CW that it can be affected by other processes in the computer, especially if you are accessing the Internet for spots at the same time. The best solution for this is to get a Winkey device which will interface with N1MM+ and generate the CW. Both of these issues could contribute to the problem. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 4 Dec 2015 10:14, Fausto Coletti wrote: > Hi all, > > I noticed a problem with N1MM + in CW. > When I select a speed higher than 28-30wpm, the weighing between points and lines changes and, > at 40wpm the transmitted message becomes incomprehensible. > Any suggestions? > > 73, Fausto IK4NMF From ik4nmf at gmail.com Fri Dec 4 04:26:00 2015 From: ik4nmf at gmail.com (Fausto Coletti) Date: Fri, 4 Dec 2015 10:26:00 +0100 Subject: [Elecraft] Test, do not read In-Reply-To: <56615B42.3020907@gmail.com> References: <8D7F6FA8EC114D6BB48033592EE67770@PCFausto> <56615B42.3020907@gmail.com> Message-ID: Test From ik4nmf at gmail.com Fri Dec 4 09:06:08 2015 From: ik4nmf at gmail.com (Fausto Coletti) Date: Fri, 4 Dec 2015 15:06:08 +0100 Subject: [Elecraft] Test do not read In-Reply-To: <56615B42.3020907@gmail.com> References: <8D7F6FA8EC114D6BB48033592EE67770@PCFausto> <56615B42.3020907@gmail.com> Message-ID: <5D6E226A2DD0454E91CA04774821F2FB@PCFausto> Test From huntinhmb at coastside.net Fri Dec 4 10:33:36 2015 From: huntinhmb at coastside.net (Brian Hunt) Date: Fri, 4 Dec 2015 07:33:36 -0800 Subject: [Elecraft] N1MM CW issue In-Reply-To: <8D7F6FA8EC114D6BB48033592EE67770@PCFausto> References: <8D7F6FA8EC114D6BB48033592EE67770@PCFausto> Message-ID: I think the dits that N1MM makes are too short, at least to my ear.

Now that the issue has come up on its own I wish to make an observation. During the contest I heard many stations with shortened dits. They sounded pretty bad and I reckon they weren't listening to themselves else they'd have done something about it. Presuming that some of these signals were coming out of K3's [because some of these were well-known contesters] I actually got nervous and checked my own signal which, like Tom's, is generated by N1MM+ keying the K3 through DTR, but was relieved to find that my dits were okay. So there's something going on out there, and I don't know what it is, but what I do know is that keying through the USB-to-Serial is proven to work well as Tom has verified. He should know; he is a very QRQ CW op. Al W6LX >>>For keying my K3, I use the DTR line.

It uses a tiny stepper motor as you described. I have demonstrated a proof of concept for it at the Palo Alto Amateur Radio Association, and I hope to have instructions ready by the end of the year. The idea is to release complete instructions for whoever wants to build one themselves, and maybe also offer it as a partly soldered kit for people who do not want to bother with SMD soldering.

Lots of settings, all done by selecting the setting with short push or long push of the right-hand buttons and setting values with the knob. For day-to-day operation, I have the display scaling set for 24 dB full screen and set the bottom of the display so that there's a small bit of "grass" visible. It is also a VERY good idea to set display averaging to a pretty long value (top button). I use the maximum setting. What this does is cause random noise to average to zero (because it's random) and add the signals (because they are the same on every sweep). For contests or DX pileups, when there are many strong signals, I adjust the display scaling as high as 42 dB (but never higher). 73, Jim K9YC From k6dgw at foothill.net Fri Dec 4 14:19:54 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 4 Dec 2015 11:19:54 -0800 Subject: [Elecraft] [K2/KX3] Tuning a magloop In-Reply-To: References: <56611503.4020005@hawkins-zhu.com> Message-ID: <5661E75A.50305@foothill.net> Might it also work with a K2? 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/4/2015 9:56 AM, Edouard Lafargue wrote: > Hi Gary, > > I need to set aside some time to finalize it, but I have designed a > fully automatic AlexLoop tuner that is designed to work with the KX3: From matt.vk2rq at gmail.com Fri Dec 4 15:12:30 2015 From: matt.vk2rq at gmail.com (Matt Maguire) Date: Fri, 4 Dec 2015 20:12:30 +0000 (UTC) Subject: [Elecraft] [K2/KX3] Tuning a magloop In-Reply-To: References: <56611503.4020005@hawkins-zhu.com> Message-ID: Does it include a resistive bridge that presents a constant 50 ohm impedance to the radio during tuning?

It uses a tiny stepper motor as you described. I have demonstrated a proof of concept for it at the Palo Alto Amateur Radio Association, and I hope to have instructions ready by the end of the year.

The P3 or LPPAN for that matter will not always show real weak signals. The waterfall as opposed to the spectrum can be more useful here. Also, averaging,set high will help dig out the signals. 73 Tom -----Original Message----- From: Ken Sent: Friday, December 04, 2015 12:55 PM To: elecraft at mailman.qth.net Subject: [Elecraft] P3 question - few signals show on the waterfall I have a new P3 here connected to a K3. I can hear signals that do not show at all on the waterfall, and barely on the upper part of the screen. And signals that show on the P3 display do not show on the attached VGA display. I've gone over the Elecraft documentation and Fred Cady's booklet on the P3 and I do not see any sensitivity adjustment for the display. There is the level calibrate but if I move that to extremes, it throws off the K3 and P3 showing the same signal strength. I don't think that is the right adjustment for what I want.

Read Alan's explanation in the P3 manual under Spectrum Display. After all, they are two different instruments. The K3 tells you the signal strength either before or after preamplification/attenuation and the P3 gives you the relative signal strengths of the signals across the band, derived from the IF, and compensated for the k3 preamp/attenuation.

The Alexloop tuner sounds like a great idea, provided it does both at the same time. IMX I tune the loop for maximum noise in the receiver. Properly designed small loops have very high Q, so the peak is very "sharp". If I then transmit and find that the SWR is high, I'm sure the coupling between the loop and the feed line is not correct. That is, the loop at resonance is not presenting a 50 ohm impedance to the feed line. So the challenge for optimum power transfer is to adjust the coupling and tuning to get both peak noise and low SWR at the same time. If you are not worried about feed line losses, I would expect the loop to work just fine using the ATU at the rig to compensate for the odd impedance presented to it by the feed line, but be sure to check the loop tuning after the ATU does its job since it will interact with the loop and shift its resonant frequency somewhat. It's like two people standing up in a rowboat. You both work together or you both get wet. 73, Ron AC7AC From k6dgw at foothill.net Fri Dec 4 16:59:56 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 4 Dec 2015 13:59:56 -0800 Subject: [Elecraft] [K2/KX3] Tuning a magloop In-Reply-To: <006101d12ed8$0a661190$1f3234b0$@biz> References: <56611503.4020005@hawkins-zhu.com> <006101d12ed8$0a661190$1f3234b0$@biz> Message-ID: <56620CDC.70101@foothill.net> On 12/4/2015 1:09 PM, Ron D'Eau Claire wrote: > IMX I tune the loop for maximum noise in the receiver.

While the RX noise peak *is* quite narrow, especially on 40 and 30, it is still quite a bit broader than the resonance point. I've occasionally gotten the look to resonance with the RX noise peak, but it's pure luck. > > If I then transmit and find that the SWR is high, I'm sure the > coupling between the loop and the feed line is not correct.

The Alex is designed to present 50 ohms *exactly at resonance*, nothing else is required. Also true for MFJ. Once I've peaked the noise, I put the K2 into TUNE and adjust for an SWR of 1.0:1. It is much narrower an adjustment than the RX noise peak. No ATU, ever. > If you are not worried about feed line losses, I would expect the > loop to work just fine using the ATU at the rig to compensate for the > odd impedance presented to it by the feed line, but be sure to check > the loop tuning after the ATU does its job since it will interact > with the loop and shift its resonant frequency somewhat. Uhhh ... no. No ATU, ever. Everything is done with the little knob on the loop while watching the SWR. Conveniently, my K2 displays the SWR. No ATU, ever. This is an amazingly simple antenna to adjust, I'm a little surprised at the length of the thread. Many years ago [OK, decades ago :-)], I built a little analog phase detector from a QST, CQ, or 73 article. It powered a small DC motor connected to a variable cap that drove the reactance on the 75 m antenna on Dad's car to zero. Worked real good. Not sure why it wouldn't work with the loop since "resonance" = zero reactance. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org From edouard at lafargue.name Fri Dec 4 17:04:22 2015 From: edouard at lafargue.name (Edouard Lafargue) Date: Fri, 4 Dec 2015 14:04:22 -0800 Subject: [Elecraft] [K2/KX3] Tuning a magloop In-Reply-To: <56620CDC.70101@foothill.net> References: <56611503.4020005@hawkins-zhu.com> <006101d12ed8$0a661190$1f3234b0$@biz> <56620CDC.70101@foothill.net> Message-ID: On Fri, Dec 4, 2015 at 1:59 PM, Fred Jensen wrote: > On 12/4/2015 1:09 PM, Ron D'Eau Claire wrote: > > Uhhh ... no.

A small loop, like any other antenna, can be designed for any impedance feed line. If a given loop happens to present a 100 ohm impedance at the feed point, 50 ohm coax will see a 2:1 SWR. That will result in some oddball impedance at the transmitter, depending upon the electrical length of the feed line. If the transmitter output network (e.g. ATU) can match that impedance, all is good providing you are happy with whatever losses occur in the feed line. As I said, it's a balancing act. Messing with the termination at the transmitter end of the coax to match the impedance presented will shift the resonant frequency of the loop; the adjustments are interactive. If your loop is designed so that it always presents a 50 ohm termination to a 50 ohm feed line at all frequencies you need not adjust the rig's output network. None of the homebrew loops I've built maintained that match across the various bands. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Fred Jensen Sent: Friday, December 4, 2015 2:00 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] [K2/KX3] Tuning a magloop On 12/4/2015 1:09 PM, Ron D'Eau Claire wrote: > IMX I tune the loop for maximum noise in the receiver.

This is in direct violation of our "keep it friendly" list policy. A note to aspiring list police: Please restrain the urge to email someone or the list admonishing them about a posting. The last thing we want to do is to scare anyone off the list. As the 'official' list Cop, I'll jump in as necessary to keep everything orderly. I do this off line and occasionally to the list when it is appropriate. Our goal is to keep the Elecraft list a fun, informative central clearing house for Elecraft and Ham Radio related information and enthusiasm. All questions are welcome, and it is in direct violation to personally criticize a poster for making a post with abusive emails. (Even if the information they seek is basic, is on our web page or is available via the list archives, its OK to ask about it.) Anyone receiving private emails (via the list or direct email) belittling or chastising them regarding a post should **forward** that post to me as list manager. List members who violate this guideline by abusing others risk permanently being removed from the email list. It is also not necessary to defend Elecraft and to personally criticize a poster who has a critique or problem with our radios. (We have pretty thick skins ;-) We want to hear critical input so we can continue to improve our products and make them the best possible. Its certainly OK correct posters if their information is incorrect, and to help them with questions or misunderstandings, but please do it politely and with respect. Overall, the primary list guideline is to keep all discussions cordial and polite on the list and on follow up private emails related to list discussions. There is no place for belittling or chastising of list members when you do not think they should have asked a question or made a post, or if you disagree with their point. Its OK to have polite disagreements and discussions, but not to make it personal. All questions are welcome. Period. The bottom line: If you have a question - POST IT. If you are having fun - POST IT. If you are having problems - POST IT. If you have a suggestion - POST it. If you have a complaint about the list or another poster - do not post it to the list. Please send it to me. We'll jump on it right away. 73, Eric WA6HHQ Chief Elecraft cheerleader and list Moderator.

Please save this for future reference. The most important thing to remember is that this is a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a polite and enjoyable forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share experiences using our products, troubleshooting ideas etc. The Elecraft email list server (reflector) is provided to further the discussion of Elecraft products and related items. It serves as a forum for the discussion of both technical and operating topics including product features, construction and debug problems, sharing your enthusiasm and impressions from using our products and more general ham radio related topics of interest to our customers. (Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 posts. Once it hits ten posts do not reply at all (go off list if you feel the urge to continue.) Also, please do not try to always get the 'last word'.. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft at mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1xyz at arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w1aw at arrl.net from your physical address of joe at aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and sent to you each month). 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Top posting is the official standard for this list, and its especially important for those of us who also read our email on smartphones, iPads etc. Scrolling though a long thread before getting to the reply text is difficult on these devices and costs everyone a lot of time. Reading the response first, at the top, is a huge time saver, especially when you have to read hundreds of emails daily as we do here. We really appreciate your adherence to this. Please also delete -all- footers and as much of the prior email text as possible when replying to cut down on overall email size. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the Nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With thousands of list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building, using and troubleshooting their rigs. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line. Examples: "Subject: [K3] Filter Options" "Subject: [KX1] How to use ped portable?" "Subject: [XG2] Wow! Its a big help. 5. *** IMPORTANT - PLEASE KEEP ALL POSTINGS CORDIAL. Restrain the urge to email someone admonishing them about a posting, or snidely commenting on it. The last thing we want to do is to scare anyone off the list. Overly aggressive postings, arguments and negative comments about other posters only serve to scare away new potential Elecraft community members. Waiting over night before hitting 'send' really helps to put things in perspective.. Remember that -everything- you post here is archived and publicly visible for as long as the internet exists. Do you really want your friends, employers, kids etc. reading what you just posted in anger, foolishness, arrogance etc? If you have a complaint about someone or a thread please email it directly to me ( eric at elecraft.com ) and I'll address it. Please do not post complaints about other postings to the list. 5a. Do not post publicly or privately asking people to stop a particular thread, no matter how long, off topic or repetitive it gets. Email me instead. I will step in when I feel it is necessary to end a thread. (eric at elecraft.com) 5a1. Please exercise restraint in posting when a thread is getting heavily covered. 10-15 posts on one topic in a day is excessive. Please do not vote yay/nay or with 'me too' postings. That only clogs our email in-boxes. 5b. Please do not post any direct attacks or snide comments directed at a list member. Enthusiastic arguments are encouraged, but please keep everything cordial. Members who verbally attack or denigrate another (either via the list or via direct email) may be removed from the list. As the only official list moderator, I'll jump in as necessary to keep everything orderly. I do this off line and occasionally to the list when it is appropriate. Our goal is to keep the Elecraft list a fun, relaxed and informative central clearing house for Elecraft information and enthusiasm. 6. There are -no- stupid questions. Please feel free to post your technical questions and comments to the list. (And absolutely do not criticize posters for their questions either on list or via direct email.) Elecraft owners are your best source for quick answers (and they NEVER sleep!) If you don't get the answers you need from the list please email us direct at support(at)elecraft.com , which is our customer service address. We do try to watch the list traffic, but we may not respond to everything immediately and may miss some postings sent to the list or our personal addresses. 7. Please do post your experiences with your Elecraft kit, DX worked, crazy ideas, product ideas, complaints (yes - we do want to hear them, but please keep it polite . 7a. Commercial postings are allowed if they relate to Elecraft products, QRP, QRO, home-brewing, building etc. and are of interest to this list's membership. Please keep them as short as possible and provide web links to more detailed information. I'll step in if we feel someone is posting too many messages of this type. 7b. Please limit commercial postings to one per month per offering or product area (i.e. Builder for Hire postings, ham radio related products etc.) 8. Also, please -DO NOT USE CAPS- to emphasize words or phrases. This is interpreted as shouting rudely on the internet. If you want to emphasize something, surround it with -dashes-. 9. Send parts requests direct to parts at elecraft.com, instead of to the list. 10. If you don't get an answer to a question from the list, or by searching the list archives, don't forget to check the Builder's Resource Page at http://www.elecraft.com and our support email address: support at elecraft.com 11. Please note that Wayne, myself and our support staff do not read 100% of the emails on this reflector - especially when we are busy at hamfests, ramping up new products in production etc. If you expect us to reply to a posting, and we do not do so, please email us directly or contact our great guys at support at elecraft.com 12. And above all, HAVE FUN!. We hope that this list is both a good technical resource and that it serves as a Elecraft community gathering place. We enjoy reading it every day and it really helps us keep our energy level high so we can continue getting exciting new products out the door to you! 73, Eric WA6HHQ Elecraft COO, List Moderator, Modulator etc. From tomb18 at videotron.ca Fri Dec 4 19:06:37 2015 From: tomb18 at videotron.ca (Tom) Date: Fri, 04 Dec 2015 19:06:37 -0500 Subject: [Elecraft] New release of Win4K3Suite Message-ID: <58B30CF734BB4CAC9F5D155705BCE2F5@tomsPC> Hello, Just a note that there is a new release of Win4K3Suite out there. Release 1.778 has a couple of bug fixes where some text colors were not correct in the Frequency Memory display for a small subset of users. This has been fixed and while I was at it, Scanning as supported by the K3, K3S and KX3 added. This release also supports the old pre-XP Windows Classic theme since there seem to be many people still using it. In addition, this release now has preliminary support for 4K monitors with the Panadapter. This allows up to 3840 x 2180 resolution for the panadapter. This works quite well, but the downsampling has not yet been optimized. The next release will offer this. It is quite a sight to see a 4K panadapter spanning 192 kHz on a 40 inch 4K display!

It monitors serial communications on the ACC1 of the KX3. From this it pulls the KX3 operational frequency (AUTO INF must be set) that it compares to the frequency the loop is currently tuned to. If these frequencies are sufficiently different and the loop needs retuning, the KX3 is disconnected from the Alex Loop using a coaxial switch and a Fox Delta DDS then excites the loop at the KX3 frequency and an algorithm varies the angular position of the variable cap to minimize VSWR - similarly takes about 10-20secs. When the loop is returned to resonance the coaxial switch reconnects the KX3/disconnects the DDS and a logic line allows the KX3 to go into TX if required. This circuit does include a balanced bridge at 50 ohms and can't place any strain on the KX3 as it's not connected during the tuning process. I'm currently implementing the serial read of ACCI, after I've got that done I'm going to look at DDS options. All the components are controlled by the Arduino Uno - which is a fun device to play with.

That said, there may be an overlap between the two tasks. W1AW starts its CW practice speeds fast and then slows down. Presumably, as the speed get slower the mental demand lessens and copying becomes easier; then, ease of copying starts occurring at higher speeds over time/trials. From my days studying animal learning, I remember significant research to the effect that starting a new task in the easiest form [slow CW speed] lessened/prevented errors and, by the end, resulted in quicker and more accurate learning. I tend to practice 3-letter groups at 35-40 wpm, 5-letter groups at 30-35 wpm, and 7-letter groups at 25-30 wpm [for better or worse]. This is somewhat geared to DX contesting since call signs are not "words." All that said, I'm starting to wonder if the animal study folks may have a point. How about the reverse of the above approach. For example, start with 3-letter groups at an error free speed, slowing increasing speed as long as the error rate stays under some value [5%, say]. Keep working at a given speed until the error rate is reached, then increment. Proceed in this fashion until a goal speed is reached. Then, repeat in the same fashion for longer letter groups. The same approach could be used with numbers, complete call signs, and sweepstakes type exchanges. The general idea is to minimize the error rate so that only correct neural networks are formed in the brain. These can be slowly stretched, perhaps like increasing strength in weight training and increasing range of motion after orthopedic surgery, all the time working at the edge to slowly increase capacity. This might also be applicable to increasing the speed of characters as in the Farnsworth method.

You start with two letters at the final speed you wish to copy, none of this Farnsworth business of fast characters with extra space between words to slow the wpm down. You want to learn 40wpm, characters and words are spaced for 40wpm. You don't add a letter until you copy the original two at 95%. G4FON makes a fine piece of software specifically designed to support the Koch method.

I've been "pounding brass" as a Ham and commercial and military radiotelegraph operator since I passed my Novice license in 1952. I enjoy CW like many Hams enjoy casual SSB or FM QSOs; it's a way to carry on lengthy conversations (rag chews). Others use CW mostly for contests. The demands are different. I got my last ARRL code proficiency certificate at 35 WPM about 1970. That was copying by ear and on a mill (typewriter - computers weren't around then) a full minute of plain text with no idea of what was coming next -- such as what one encounters in a rag chew. But my rag chews are invariably 20-25 wpm or less. That's what most other operators are running and it allows me to putter around the shack while copying easily "in my head". In a contest I can follow an exchange at 40 wpm or higher because I know exactly what to expect and only need to copy the variables - number, section, etc. Perhaps for learning CW for contesting starting at the higher speed is better, possibly using "Farnsworth" spacing in which highly exaggerated spaces are left between letters at first and then slowly moving into a normal spacing. For me it was as you suggest, from slow speed and then upward, always striving to keep the proper element and word spacing. One thing I've come to expect is that when learning code "your mileage may vary" is certainly true. The "best" way for each of us is how each of us learned! 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Robert G Strickland Sent: Friday, December 4, 2015 7:22 PM To: Elecraft Subject: [Elecraft] [OT] increasing CW copy speed: practice slow -v- practice fast The following comments/questions focus on increasing CW copying speed, not the task of initially learning the code.

Take the heatsink off and again measure the resistance between ground and the collector of Q7/Q8. If it is then OK, simply get new thermal pads. Yes, F1 trips very quickly.

As I remember, there was not a lot of clearance there, especially with the adapter board for the encoder. I?d be looking for possible shorts around there. Just a comment on your observations with F1 ? if you are applying power and measure 0V on both sides of F1, then that suggests that F1 is not open circuit.

The leads on the encoder board must be flush trimmed (really close to the board), and the area of the Control Board behind the encoder board must also be flush trimmed. You might even want to put some electrical tape over the back of the encoder board as an added preventative measure. Another thing you can do to increase the clearance between the front panel encoder board and the Control Board is to add a 2nd lockwasher between the 2 front panel standoffs and the FP board. That will increase the clearance slightly. 73, Don W3FPR On 12/4/2015 9:35 PM, Dauer, Edward wrote: > Tegsting out the newly built K2 tonight. Everything was working just > fine.

It could be that the 0 volts is the result of your power source folding back or the soldering of D10 or the soldering of the power jack. In any case, cure the low resistance at the collectors of Q7/Q8 first - that low resistance indicates a direct short for the 12 volt power input. Once that is solved, you can move on to other potential problems. DO NOT attempt a TUNE or Transmit with the heat sink removed - doing that will kill the PA transistors very quickly. 73, Don W3FPR On 12/4/2015 11:36 PM, Matt Maguire wrote: > Good move taking a rest and a glass of wine ? it is important not to panic, as that can lead to doing something silly :) > > If you were entering 10000, you would have been tapping the ? 0 ? key next the the VFO knob multiple times, and maybe the pressure has caused the front panel and control boards to come into contact and short out.

That said, there may be an overlap between the two tasks. W1AW starts its CW practice speeds fast and then slows down. Presumably, as the speed get slower the mental demand lessens and copying becomes easier; then, ease of copying starts occurring at higher speeds over time/trials. >From my days studying animal learning, I remember significant research to the effect that starting a new task in the easiest form [slow CW speed] lessened/prevented errors and, by the end, resulted in quicker and more accurate learning. I tend to practice 3-letter groups at 35-40 wpm, 5-letter groups at 30-35 wpm, and 7-letter groups at 25-30 wpm [for better or worse]. This is somewhat geared to DX contesting since call signs are not "words." All that said, I'm starting to wonder if the animal study folks may have a point. How about the reverse of the above approach. For example, start with 3-letter groups at an error free speed, slowing increasing speed as long as the error rate stays under some value [5%, say]. Keep working at a given speed until the error rate is reached, then increment. Proceed in this fashion until a goal speed is reached. Then, repeat in the same fashion for longer letter groups. The same approach could be used with numbers, complete call signs, and sweepstakes type exchanges. The general idea is to minimize the error rate so that only correct neural networks are formed in the brain. These can be slowly stretched, perhaps like increasing strength in weight training and increasing range of motion after orthopedic surgery, all the time working at the edge to slowly increase capacity. This might also be applicable to increasing the speed of characters as in the Farnsworth method. I'm interested in what folks think. ...rober -- Robert G Strickland, PhD ABPH - KE2WY rcrgs at verizon.net.usa Syracuse, New York, USA ______________________________________________________________ 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 danny.higgins at keme.co.uk From vk2jng at icloud.com Sat Dec 5 05:25:49 2015 From: vk2jng at icloud.com (Gerard Elijzen) Date: Sat, 05 Dec 2015 21:25:49 +1100 Subject: [Elecraft] KX3 and PX3 screen flickering when scanning.

However I would also question whether F1 would produce a popping sound, although it might through thermal effects, or by affecting the power to the audio chain. F1 isn't a circuit breaker; it is effectively a rather aggressive positive thermal coefficient (PTC) thermistor. When the current gets too high, the temperature goes up, this causes the resistance to increase, which increases the heat generation for the same current, and you have a thermal runaway. The resistance goes up so fast that it limits the current in the device severely before the device gets hot enough to self destruct (although its on resistance is permanently raised), and the actual current needed to keep it hot is quite low. Once the current demand drops below the triggered state current, it will begin to cool, and at some point, as long as the current remains low, it will cool faster than it is being heated and the resistance will drop to the point where increasing the current won't cause an immediate runaway. In the triggered state it reaches an equilibrium, letting through enough current to keep it in the high resistance state. It's not like a bi-metal circuit breaker that has no self heating once triggered and will eventually reset given just time. On the other hand, I imagine there are some load conditions in which a polyfuse would go into a slow oscillation. https://en.wikipedia.org/wiki/Resettable_fuse -- David Woolley Owner K2 06123 On 05/12/15 04:36, Matt Maguire wrote: > > Just a comment on your observations with F1 ? if you are applying power and measure 0V on both sides of F1, then that suggests that F1 is not open circuit.

Using an ATU in place of properly resonating a Magnetic Loop is a no-no. If the loop, at resonance, doesn?t provide a good match to 50 ohms, then it is ok to use the ATU to ?fix? the mismatch. Note the use of ?fix? in quotations. You are really not fixing anything, just making the rig see a resistive 50 ohms or something close to it so that it is happy to deliver full power to the loop. You will incur some additional losses in the tuner, but they are likely minor. Just make sure you properly resonate the loop before kicking in the ATU. One additional point worth mentioning. A Magnetic transmitting loop fed via a coupling loop works like a transformer. The 1 to 5 ratio between the size of the coupling loop as compared to the main loop provides an impedance transformation that should normally give a good match to 50 ohms. If, at resonance, you are consistently seeing an SWR higher than what you would like then it is possible to tweak things by either slightly moving the position of the smaller coupling loop, or by slightly deforming the coupling loop in the vertical plane (i.e. making it rounder or more oval). It is usually easier to just bend the coupling loop. The process is trial and error but usually you can find a configuration that will yield a pretty good match on all bands covered by the loop. I had to do this with my MFJ-1786 Hi-Q Loop as the best match I could get at resonance was around 2:1 SWR. With a bit of tweaking it now typically around 1.5 : 1 SWR on most of the bands. Michael VE3WMB P.S. Manually resonating a loop by ear is an acquired skill. With practice, peaking band noise will get you very close to resonance without transmitting. Then with a second or two of applied RF, aided by feedback from an SWR meter, you should be able to hit the loop resonance point pretty much dead-on. >From: "Ron D'Eau Claire" > >Date: December 4, 2015 at 4:09:18 PM GMT-5 >To: "'Elecraft Reflector'" > >Subject: Re: [Elecraft] [K2/KX3] Tuning a magloop >There are two parts to tuning a small transmitting loop antenna: Resonating the loop at the >operating frequency and matching the loop at resonance to the impedance of the feed line. >The Alexloop tuner sounds like a great idea, provided it does both at the same time. >IMX I tune the loop for maximum noise in the receiver.

Unfortunately GWBASIC died with the advent of Windows3 and other versions of BASIC did not have the BEEP command that was used, but recently I have rewritten the program in Python and it runs on a Raspberry Pi2 at least up to 50 WPM.

This is somewhat geared to DX contesting since call signs are not "words." All that said, I'm starting to wonder if the animal study folks may have a point. How about the reverse of the above approach. For example, start with 3-letter groups at an error free speed, slowing increasing speed as long as the error rate stays under some value [5%, say].

El Numero Uno contest QSK problem, with nothing in second place, is QSK dealing with amplifiers that will not do T/R turn-around (including the relay points *settling*) in less time than the space between dits :>) The manufacturers do not want to deal with it because it's either expensive and tricky with relays, or it's pin diodes that get whacked at full QRO from transmitting into an open, static on the antenna, lightning induced pulses, etc. Some hams do fine with the pin diodes and others have nothing but trouble with them, depends on a lot of things. Some transceiver manufacturers simply clip the keyed input if the delay is too long, a defensive solution resulting in short dits but *not* burning amp relays or carbon-arcing amplifier bandswitches. Myself, I have given up on contest QSK, and let my microHam u2R handle providing PTT to the amp and delay to the u2R generated code. Since the u2R (not the K3) converts both ascii data via a serial cable from the PC and my paddle input to keyed line, and it uses the WinKey chip to do most of that, it is also in a position to slightly delay the onset of morse output just a little behind a PTT output. That delay can be set to match the most atrocious T/R relay, including an old unmodified AL1200, with never a clipped dit. That is separate from the ancient problem of a computer not quite having enough processing power to handle the operating system AND generate pristine on/off morse code key output. Again some do OK generating code this way and others have awful problems with it. The reasons why or why not are often not clear at all. These issues have gigabytes of postings on the subject in the various ham archives, rehashed ad nauseum as the subject comes up over and over again over the last two decades. It certainly is anything but an recently emergent problem. With my settings, the Alpha drops at the end of each letter, which is good enough to hear if someone already started sending under me and I can stop paddling or hit escape. I gave up on contest QSK not because of the K3, but because of the general issues that touch everything, and I am tired of replacing relays in amplifiers and finding out I have clicks when the contacts go bad. When there is a transistor full QRO amp using battleship grade pin diodes, where the entire amp is as reliable as the KPA500 or my tube Alpha, **and that does not exceed the rest of my station in purchase price**, I'll switch. But I *continue* to hear stories about pin diodes and transistor amps blowing finals, even if some insist that theirs have always been fine (God bless them, I envy their good luck). Last night in the ARRL 160 contest there was a K0 station that could not send "IA" for his section. Before dit-dropping occurred to me, he was sending "EA" for section and I was asking for a fill. 73, Guy K2AV On Fri, Dec 4, 2015 at 12:44 PM, Al Lorona > wrote: > Right after the CW SS I composed a message for the list, then trashed it > after sleeping on it which I always do before posting.

This is a "pileup" generator, where multiple calls come concurrently, at varying speeds & tones, with background noise. http://www.dxatlas.com/MorseRunner/ There was an old Commodore "Dr. DX" program that I still have around here somewhere that was an early version of this sort of function. N6MJ claimed 10,223 QSOs as a single operator (two radio) in CQ WW CW at ZF2MJ last month. Dan says he trained for months with two laptops running MorseRunner, one in each ear. https://www.youtube.com/watch?v=no8nGGa99cE http://www.3830scores.com/showrumor.php?arg=Lwa6zEfymmyvJ This was a remarkable performance. > 10K QSOs as a single op? That's an average of 3 contacts a minute, for 48 hours. He has a 10 minute spurt of 414 an hour.

I spend most of my practice time with Rufz, occasionally going to Morse Runner. I'm not drawn to G4FON's program, because there's no way to interact directly with the program as it generates code [as with Rufz]. Focusing on Rufz, my initial post basically asks about a comparison between starting at the target speed and working down or at a slower speed and working up. I'm quick to acknowledge that all methods/approaches presume that one puts in the practice time to become proficient. If one wants to increase cw proficiency, then spend a lot of time in cw qso's. No free lunches. Recently, when working at the computer on business, I tune in a cw qso and just let it go on "at the back of my attention" as I work. This seems to be having some positive effect. What I personally find happening - I'm 75y/o - is that in higher speed qso's I start slowly lagging behind the sender until I miss a word/words that breaks the intelligibility of the conversation. Frustrating! Another point, I think that copying call signs at high speed is more demanding in that one doesn't have the conversation stream/meaning to help fill in for missed words. ...robert On 12/5/2015 03:21, Robert G Strickland wrote: > The following comments/questions focus on increasing CW copying speed, > not the task of initially learning the code.

Inter-alia the covenants stated that no "TV dish antennas" may be erected on property, but with ever changing technology and a deteriorating Cable TV service, most residents now have a dish antenna and so that "rule" falls into the category of dis-use. Then there is the advent of "drones"; there are no rules governing the use of drones in the community, therefor, amidst uproar from the community, many drones are used as a hobby, uncontrolled, with no consequence! My "proposal" for an antenna to the HOA clearly stated these anomalies in their management process of the property and I clearly stated and included in my proposal as much detail of the Radio Parity Act, together with copies of my correspondence to our Florida Senators in Congress. I am happy to report that after submission of a detailed proposal; it was not a week later that I received permission for the erection of a 30 ft vertical, it may not be much, but it was a great start to keep my interest going in what I hope will be a long association with Ham Radio.

Diversity mode works by feeding two slightly different signals into a single brain that is programmed from birth to cope with two such inputs (two ears) and synthesize them into a combined information stream, using the phase and amplitude differences to add information value. The RTTY decoders I am familiar with don't do that; they are monaural. If you want to use two separate monaural decoders on the audio inputs from the two receivers, don't use diversity mode, just turn the subRX on and let each decoder decode its own input stream. If the two VFOs are not linked, each receiver would be listening to its own frequency (SO2V), but if you link the two VFOs (CONFIG:VFO LNK = ON), you can force both receivers to listen to the same frequency (presumably on different antennas, else what's the point?). This is different from "diversity decoding", which uses two different decoding algorithms on a single audio stream so you can compare the results of the two algorithms and pick the one that works best under the current instantaneous conditions. You don't need a second receiver for that; you can use an arbitrary number of decoders using the same channel of the same sound card and get the benefits of diversity decoding even with a single receiver. 73, Rich VE3KI W1UE wrote: > When the K3 is put into Diversity and the mode is RTTY, the Line out Audio > for the Sub Rx disappears.

First, I want to say again how much I appreciate not just this reflector, but more so the people who participate in it. Last night, within 20 minutes I had six replies from, literally, across the globe, every one of them encouraging and helpful. Thanks, guys. Second, for anyone who likes solving puzzles, I am reprinting below my recent off-list message to Don Wilhem, W3FPR, to whom the rig will be going for further investigation. Submit your diagnoses and I?ll let you know what Don discovers once he actually has the rig on his bench. No prizes available, but it might be fun . . . Here?s the latest status report: ___________________________________________ This morning the symptoms remained: No LCD light, popping noise in speaker, voltages at either side of F1 were 14 with power switch off and essentially zero with power switch on. The same on both sides of D10, and the same at the accessory DC power pins. Resistance from Q7 and Q8 cathodes to ground was about 2 ohms. 1. Removed control board and front panel board; tested RF board alone ? same symptoms (low resistance and apparently a short somewhere on the 13 VDC line.) So those boards weren?t the problem 2. Reassembled everything and then removed the heat sink. Resistance measurements at Q7 and Q8 unchanged. Examined thermal pads, checked shoulder washer placement and all associated hardware. No changes ? still low resistance from collectors to ground. 3. Reassembled and tried it again. No change ? no lights, popping noise in speaker, voltages as in step 1 above. 4. As a last ditch effort, decided to change power supplies (had been using an MFJ rated at 40 watts.) Made up a cord to connect K2 to a known good supply with a built-in ammeter. I thought I?d be able to see a current spike if there was a short, as F1 opened and closed. The K2 came to life and the current draw was nominal (less than 200 mA.) Switched back to the MFJ supply. That worked too. Problem solved? No. See number 5. 5. Decided to see if it really was cured. Connected K2 to a known good dummy load, through an SWR meter. Keyed it with power set to 10 watts ? but the forward power needle set for full scale barely nudged. Checked the power output as read by the K2?s onboard power meter. It read 0.5 watts, no matter where the power control is set. Confirmed that current maximum in the configuration menu was set at 3.5. It was. Tried the same routine with a known good antenna connected (measured SWR at less than 1.2:1) Same results. I don?t know what all this means, but I am going to take a wild guess. Last night something ? maybe Q7 or Q8 but maybe something else ? developed an internal short at exactly the instant I did a direct frequency entry of 10.000 Mhz (a relay clicks at that point). This morning, for whatever reason, when I changed power supplies, I am guessing that whatever had been shorted (or nearly so) burned out, creating an open circuit where there had been a low-resistance fault. Since the rig is producing 0.5 watts but not more, that makes me think it may be one of the output transistors. Note that, until last night, it happily produced as much as 15 watts. In any case, the rig came out of its coma but now it can?t speak. And maybe it can?t hear. Tthe receive function also seems to have been degraded ? I heard no signals when the antenna was connected ? though I can check that further by using the K3 to see if anyone is on the bands and comparing it to the K2. So, what do you think is going on?

There is little difference in price between the PR6-10 and the KXV3B.I had been waffling on the 6m preamp for years and when I saw the new XV board, I jumped. No regrets here. My noise floor is very low on 6, 10, and 12 so it does help a bit. Honestly though, I have seldom used the second preamp on 10 or 12 but 6m, definitely. 73,Jim, W5QM On Saturday, December 5, 2015 12:07 PM, SCDolphin0 wrote: Has anyone upgraded the K3 with either KXV3B, KIO3B or both and any comments?

You don't need to buy a book to know what I think about it. I found both upgrades quite worthwhile. The synth board makes your signal cleaner and reduces RX phase noise when the band is full of strong signals. It can be a very big deal in contests and with big DX pileups. The new synth board, combined with a mod to the KBPF3, also enables high quality reception below 500 kHz. It's VERY easy to install. Guys running QRQ say that it improves high speed CW significantly (I rarely work above about 34 WPM). If you have the Sub-RX, you must install two of the new boards. The KXV3B includes the new preamp, which helps a lot with weak signals on 12, 10, and 6M. Installation is more of a challenge mechanically, because physical tolerances make it a bit of a "shoehorn job." That's as far as I've gone with upgrades -- I'll upgrade to the new KIO3B only if it corrects the glaring Pin One Problems present in the original KIO3, which I consider the biggest design mistake Elecraft ever made. 73, Jim K9YC From ab2tc at arrl.net Sat Dec 5 14:18:24 2015 From: ab2tc at arrl.net (ab2tc) Date: Sat, 5 Dec 2015 12:18:24 -0700 (MST) Subject: [Elecraft] Mods to K3 In-Reply-To: <56632CD3.5040906@audiosystemsgroup.com> References: <56632CD3.5040906@audiosystemsgroup.com> Message-ID: <1449343104086-7611142.post@n2.nabble.com> Hi Jim, Well, I decided to upgrade to the K3S. The old K3 will replace my IC7200 as the "to-go" station. The 7200 is more than adequate for my use, but I have become so dependent on the panadapter with my K3(which the 7200 cannot support) that I decided on the upgrade. The "to-go" station is mostly used in the back yard deck on nice summer days. The new USB port is wonderful. I use it both for control (with HRD) and audio. One surprise I got was that the factory setting (010) for the line output (yes, that setting affects the USB audio level) was driving the audio right into clipping. I had to reduce it to 002 to be comfortably below clipping level. The audio is fairly clean: ab2tc.com/new_k3s_usb.png There is still some junk around 3.9kHz (it's always there regardless of whether there is a signal in the passband or not.) The test signal is a -73dBm signal from the XG3. The radio is in USB mode with passband 300-2700Hz. So, Jim, I would recommend the KIO3B. The pin one problems should be gone since you don't need the RS232 port and the line out anymore. I agree that the new preamp helps a lot on 10m (and undoubtedly on 6m which I don't use). I have the S-meter set for "absolute", but it does not yet work with new preamp. Hopefully Elecraft will correct that soon. I am a happy camper with my new K3S.

The Farnsworth method of CW training was the most beneficial to me. With Farnsworth the characters are sent faster than the words. For instance at 10wpm each character is sent at 20wpm but enough time is added to slow down the rate to 10wpm. The ARRL adopted this method years ago for their morse code training materials and the W1AW morse transmissions. For example when W1AW is sending at 18wpm the characters are sent at 20wpm. Its great to get time in the saddle copying QSO's but to really increase your copying speed you really need to spend some time exercising your copying abilities each day. Practice copying "only" at speeds faster than you can comfortably copy. Practice at a speed where you are only able to copy one or two characters in each word. Concentrate !! Do this for only 10 minutes each day. If you are really concentrating you will find 10 minutes is about when you are ready to throw in the towel for the day anyway :-) Later on after you find you are able to copy about half of the text then increase the speed back to where you can only copy one or two characters in each word. (This isnt supposed to be easy this is a training exercise.) We wont increase our copying speed by copying the same easier speeds all the time. Try this only ten minutes a day and see what happens ! Also don't fret over losing a word or words in a conversation and losing the intelligibility of the conversation, that happens to all of us and will be remedied when you copying speed is increased. my two cents Bob K6UJ On 12/5/15 9:03 AM, Robert G Strickland wrote: > I have used all the programs mentioned in this thread and have found > them all useful.

The pin 1 problems continue to exist because the return of the line in, Line out, and rear panel mic jacks are not tied directly to the chassis. They still follow an indirect path through the jack board, a pin header, to the KIO3B and through another pin header to the RF board and finally to the main circuit common/chassis. Line in/Line out actually "float" through audio transformers ... USB does not have a pin 1 problem but that dos not resolve existing issues with the microphone input or the "pin 1" issues (failure to tie the signal returns to the chassis *at the jack*) for all of the other signals that pass through the KIO3B board. 73, ...

The speed you use to practice is not important, it is writing down the letter when heard, over and over again. K7QO has a CW program on his site which does just that. Also, it is finding the time and dedication to put in the time needed. K7QO by the way has won copy contest at over 100wpm, he knows what he speaks. Just my two cents. Now, back to the practice. 73 and good DX Bill KC4ATU On Dec 5, 2015, at 2:37 PM, Kevin Stover wrote: > I've always thought the Farnsworth method was directly responsible for the "10 wpm wall" newcomers were running into.

The cardboard trim around the speakers is thicker than the fiber washers therefore the speaker ears do tend to bend. The washers should be thicker or the speaker ring should be thinner. Anyway....Leaving bolts this loose isn't good construction practice anyway. Surely a better method of attaching a simple speaker to a piece of metal can be found.

Ron (Tech writer) AC7AC here. After r/r the speaker in a K3, K3 and K3S many times, I have managed to make little dimples in the frame ears around the lock washers and nuts. But that does not damage the performance of the speaker. As you probably know, the distortion and buzzing occurs with the voice coil attached at the center of the cone rubs against the magnet. That happens when the entire frame is distorted. Such distortion can result from aggressively tightening the mounting screws so that the ring were the voice coil is attached is bent, which is why the warning in the assembly procedure. But it takes being very aggressive. It can happen as a result of handling too, particularly if the speaker is dropped, even when in its box. The magnet is heavy enough that it can bend the frame members supporting the magnet on impact. I did that once right on my workbench. It sounds like the factory accidentally may have sent you a defective speaker, since you obviously are aware of the distortion issue. Or it's possible the box containing the speaker was the victim of a shipping company "gorilla" dribbling it across the sorting table.

Originally no fiber washers were provided, and several builders tightened the screws excessively and deformed the speaker frame. That warning has been present in manuals calling for mounting the speaker ever since. The screws should be tightened securely, but not "beefed down" such as to squeeze the fiber washers enough to deform them - and that will deform the speaker frame. Like Wayne, I have not heard of this problem with the K3 or the K3S and have not heard of similar problems with the K2 after the fiber washers were introduced. There is an occasional bad speaker encountered, so I would tend to believe this is a "one-off" case of a bad speaker. There *are* two different thicknesses of fiber washers used in Elecraft kits. The thinner ones are used on the K2 PA mounting hardware, and the thicker ones are used for mounting the speakers. Perhaps Steve was sent the thinner fiber washers with his kit (that is only a guess on my part). 73, Don W3FPR On 12/5/2015 4:35 PM, ac5p at sbcglobal.net wrote: > I have an older K3 and a spare speaker (part #E850300).

I have a USB device that is not recognized in OS X 10.11. Well, that?s not entirely true. It?s recognized for how it connects (via USB) but not for what it is (an audio device). I cannot upgrade unless I upgrade (buy new) the device. The manufacturer has not made new drivers for it as of this past week sometime. It has something to do with something called the ?USB stack.? I am not a programmer nor do I pretend to know how an OS interfaces with the hardware on a computer. What I do know is that my E-MU 0204 sound card does not work in OS X 10.11. So, if Apple (or Microsoft or any OS) decides to change the way the OS operates with peripherals and manufacturers of devices won?t make a new driver, you?re hosed. Knut, I have to respectfully disagree based on my own experience just the past couple of months. 73, Joel - W4JBB > On Dec 5, 2015, at 4:27 PM, ab2tc wrote: > > Hi Joe, > > I don't share your pessimism about the future support of the USB devices (2) > presented by the K3S.

Early adoption of the latest and greatest OS always has it?s risks especially if you don?t immediately need the OS upgrade enhancements. Always make sure that all critical applications and hardware drivers you use are compatible with any new OS before upgrading. Many hw drivers often lag an OS release. Always make a complete system backup to allow reverting to an earlier OS version if disaster strikes. If the're going to be any problems others will have discovered them first. Then plan for sw and hw upgrades accordingly.

If the washers are one micro too thin you can warp the speaker. The cure is to have a spacer between the speaker and the lid. No air should leak. I think of something like a spacer for PC fans or a carburetor/manifold gasket. Just something stamped out of cardboard would be fine.

We are discussing increasing your code speed on receive. And speed is vitally important ! K7QQ is not the only one that can copy high speed CW, there are many of us out here. Transitioning to higher speed copy can be done through systematic and regular exercise. I have been a CW operator for over 40 years and it wasn't until fairly late in the game that I accepted the advice from several high speed ops on how to progress past mediocre copy speed. ( I will share this below) First we need to realize there are two distinct types of training for CW. The first is developing your rote memorization skills for learning the characters. I recommend the Farnsworth method for this. With Farnsworth the characters are sent faster than the words. For instance at 10 wpm each character is sent at 20 wpm but enough time is added to slow down the rate to 10 wpm. The ARRL adopted this method years ago for their morse code training materials and the W1AW morse transmissions. For example when W1AW is sending at 18 wpm the characters are sent at 20 wpm. Now to increase your speed you need to approach your training differently. (which is the subject of Roberts original post) There are different variations of the training used to increase your speed but they all have a common denominator. They all in some form or another introduce copying at a faster speed (go figure) Here is what I found to be most effective method for me I learned from other ops. Its great to spend time in the saddle copying QSO's in which your current copying speed will allow, but to really increase your copying speed you need to spend some time exercising your copying abilities each day by practice copying ONLY at speeds faster than you can comfortably copy. You wont increase your copying speed by always copying at the same comfortable speeds. Practice at a speed where you are only able to copy one or two characters in each word. Concentrate !! Do this for only 10 minutes each day. If you are really concentrating you will find 10 minutes is about when you are ready to throw in the towel for the day anyway Later on after you find you are able to copy about half of the overall text then increase the speed back to where you can only copy one or two characters in each word. (This isn't supposed to be easy this is a training exercise.) Try this only ten minutes a day and see what happens ! Also this needs to be practiced regularly, every day and if you miss a day, no worries, jump back in. Many hams never improve their speed and are content when they reach around 20 wpm max. In many chasing DX and contest operating CW activities it gives you an big advantage to be able to operate at higher speeds. We have all heard the high speed ops during a contest and marvel at how fast their contacts go by. It is great to be able to match their speed and grab a contact ! Its not that difficult folks, just 10 minutes a day of concentrated practice. As you are gaining your speed don't get frustrated over losing a word or words when you are in a CW QSO and losing the intelligibility of the conversation, that happens to all of us and will be remedied when you copying speed is increased. Lastly, you will with practice, increase your "comfortable" copy speed to upwards of 30 to 35 wpm and more. You will be able to really enjoy morse as a language. You will sit there and listen to sentences and paragraphs go by in your head with complete understanding. It is very enjoyable ! 73, Bob K6UJ On 12/5/15 11:54 AM, Bill Rowlett wrote: > The best way to learn CW is the same as learning any language, by the sound of the letters or charters. The speed you use to practice is not important, it is writing down the letter when heard, over and over again. K7QO has a CW program on his site which does just that. Also, it is finding the time and dedication to put in the time needed. K7QO by the way has won copy contest at over 100wpm, he knows what he speaks. > > Just my two cents.

Reading "The Art and Skill of Radio Telegraphy" Pierpont says the same thing. By stretching the time between words you give people more time to translate. if your going to copy Morse faster than about 10wpm you don't have time to translate. You have to know the character as soon as you hear it without using the look up table in your head. The Koch method has no exaggerated spacing between words or elements. You want to be proficient at 35 wpm, you practice with dit/dah and word speed set for 35 wpm. >> >> Building speed on the air is great as long as the code you are copying is "good" code meaning close to properly spaced and timed code.

All are welcome. We ask for your name, state, rig (K2, KX3, K3, or K3S) plus your serial number. Checkins using other rigs are fine as well. You can find your serial number in a variety of ways, most easily by looking in the menu under 'S'. If you would rather not share your serial number, that's fine as well. We will use relay stations to make sure we can get you checked in, as well as listen specifically for QRP, portable or mobile stations. We often have checkins from as far afield as Alaska and New Zealand. At the end of the net we will take comments or questions. I will be net control for today.

I know my CW speed jumped when I worked the high level CW nets (EAN) and suddenly HAD to copy fast and accurate! I think in a few weeks I went from 20 to 29 wpm, my limit for printing each character. There was no way I was going to keep asking for fills. It was, however, many years later until I finally broke away from printing and started copying in my head. IMO, when you get at the 35-40 wpm level, CW totally changes and starts to become more like a normal person to person conversation. Unfortunately, I was off the air for a dozen years and have not regained that speed. On a different topic you mentioned, I HATE Farnsworth. Yes, maybe it's a good way for people to learn but they fail to transistion to sending proper code. There are too many people sending Farnsworth on the air and it is improper and sloppy code. It's a shortcut to doing things right and it has a high penalty.

Is there a setting that reduces the pickup of static noise that is being converted into nonsense letters. My settings at the time were 250Hz filter and threshold was at 3 under decode settings and speed was at 5-40 wpm. Thanks in advance.

In-Reply-To: References: Message-ID: <56648990.8000202@embarqmail.com> Mike, You could try changing the decoder threshold. See "CW Decode Tips" in the manual (page 31). "Adjust the threshold so that the CWT bar flashes in sync with the received CW signal". A threshold setting of 3 is pretty low and may attempt to decode noise unless you have a very low ambient noise location. 73, Don W3FPR On 12/6/2015 1:44 PM, Mike Weir wrote: > Good afternoon, during the CQ CW contest the other weekend I used the CW decoder for the woodpecker code speed.

It's really annoying when I depart the remote radio site and forget to set both AFG pots to reasonable levels. In particular, if I leave the Sub RX gain at zero, which is where it often sits when I'm there in person, then every time I try to use the sub, its volume goes to zero and I have to wiggle the knob at the control site.

I should also note that my learning disabilities make it difficult to turn a string of letters into a word without seeing them on paper or a screen. That difficulty, and my inability to spell, resulted in my having no novice QSOs back in 1960. I do have a few observations. CW is a language, like German or Chinese (both of which I have studied). I got to be good enough with German that I could understand a conversation without translating it to English. The translation process takes too long and you lose the thread of conversation. The DX vocabulary is very small, and it is fairly easy to learn it at high speed. The major words are: CQ, AGN, ?, UP, TU, and your own call sign. Contesting has a somewhat larger vocabulary. From the 160M contest, we add: TEST, QTH?, SEC?, QRZ, 73, individual section names, and probably a few others. Note that none of these are words in any other language. To operate in the CW environment doing contesting or DXing, you will need to recognize these words the first time without having to translate them to letters, just like conversing in a foreign language. If you are search and pounce, you can get a stations call by listening to it repeated several times. Running a frequency means you will have to be able to copy calls the first time, at least most of the time. It might be useful to have a CW training system which drilled you in the major vocabulary words for the kind of CW you want to use. After you have been using CW for years, you may get to be like Ron, AC7AC and be able to have the radio on in the shack and just listen to a CW QSO, understanding without translating. 73 Bill AE6JV -------------------------------------------------------------- Bill Frantz | There are now so many exceptions to the 408-356-8506 | Fourth Amendment that it operates only by www.pwpconsult.com | accident. - William Hugh Murray From emoss98133 at msn.com Mon Dec 7 00:49:26 2015 From: emoss98133 at msn.com (KD7PY) Date: Sun, 6 Dec 2015 22:49:26 -0700 (MST) Subject: [Elecraft] Yahama CM500 help In-Reply-To: <1449464415489-7611186.post@n2.nabble.com> References: <1449464415489-7611186.post@n2.nabble.com> Message-ID: <1449467366865-7611191.post@n2.nabble.com> Thanks to everyone for all the replys.

It came loaded with the 32 bit version of Win7 Pro and I made the mistake of loading all my programs on it. Now I can't switch to the 64 bit version of Win 7 or upgrade to the 64 bit Windows 10 without losing all the loaded programs and having to reload everything. You have already informed Elecraft of this problem by posting here. The person who writes the code for the Utility monitors this list though you could also call Elecraft Tech Support (see their website for the phone#) and let them know as well.

I bought a special cable from Array Solutions that provides band data and ALC from K3 to amp. I thought that this cable would also provide relay information also, but it did not. I provided a cable labled ?relay? on the amp and ?Key Out? on the K3. I now have the K3 keying the amp. With around 45 to 50 watts drive from the K3, I am getting about 700 watts output from the THP amp. DO I NEED to also go in to the ?config menu? to set any settings for the K3 to properly adjust any relay delay, voltage keying settings etc. Previously I used this same set-up with my IC-756PRO2. The THP amp has a variable pot on the rear panel to adjust and set ALC voltage or relay voltage? for various radios. I don?t think that I need to readjust this with the K3, but not sure. I don?t want to damage the relays in either the K3 or THP amp. Has anyone on this Reflector used a K3 with the HL-1.5KFX amp?

Message-ID: <019c01d13108$d3de84d0$7b9b8e70$@verizon.net> Thank you to everyone that responded. I took the bottom cover off and immediately saw the problem - It was an assembly mistake. I had installed a standoff that was 1/32 too long on the screw holding the PA shield -- the screw at the top of the rear bottom panel that's above the right foot, looking at page 70 of the assembly manual. I replaced it with the correct length standoff, and the problem is fixed. Don't know how I missed that on assembly! Shouldn't work tired, I guess.

The THP amp has a variable pot on the rear panel to adjust and set ALC voltage or relay voltage? for various radios. I don?t think that I need to readjust this with the K3, but not sure. I don?t want to damage the relays in either the K3 or THP amp. I don't know this amplifier, but in general, it is VERY bad practice to use AGC from the amp to set drive power from a rig. Doing so usually results in bad splatter and key clicks. As long ago as the early 1980s, mfrs of decent power amps (in this case, Ten Tec) were telling customers (in the user manual) to NOT use AGC to set drive power. The K3 is very well behaved as an exciter for power amps, so the right way to set drive power is to use the Power Out knob on the K3. I've never done it any other way, including with a TS850, FT1000MP, and a K2/100. The ONLY good use of AGC between a power amp and a rig is to protect the amp if something in the antenna circuit fails. To do that, hook up the AGC and carefully set it so that it does not reduce drive power in normal operation at the highest power at which you operate. FWIW -- I have NEVER used AGC between an amp and a rig. My amps are a KPA500 and Ten Tec 425s (legal limit tubes, a pair of 3CX800A7s). 73, Jim K9YC From nf4l at comcast.net Mon Dec 7 13:28:45 2015 From: nf4l at comcast.net (Mike Reublin NF4L) Date: Mon, 7 Dec 2015 13:28:45 -0500 Subject: [Elecraft] Elecraft K3 Utility problem In-Reply-To: <7B5FA89B-11AD-4E8B-8BA3-0599E1129D62@wunderwood.org> References: <60B02A42-16B9-4A90-8BEB-D7702497D740@comcast.net> <002301d13101$9156fae0$b404f0a0$@elecraft.com> <66CB37CD-83F0-48C3-BBDB-0EE0291184AD@comcast.net> <7B5FA89B-11AD-4E8B-8BA3-0599E1129D62@wunderwood.org> Message-ID: <15A0AD8C-AAA8-46B1-8044-FDDED29F2C11@comcast.net> AMEN! 73, Mike NF4L > On Dec 7, 2015, at 12:08 PM, Walter Underwood wrote: > > That was an excellent bug report, which usually makes fixing it much easier.

Does not work vice versa (as in your request) as the K144XV only connects to the main RX (plus the sub RX if you share both, that would mean VFO A + B both on 2 m). Also take a look at the RX switching PDF on the Elecraft website for deeper insight into possible RX path'. 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 07.12.2015 um 21:58 schrieb Alan Muldawer: > I have a K3 with the second receiver KRX3 and I also have the internal 2 > meter card K144XV and what I would like to do is to be on 6 meter, VFO A > and to listen to 2 meters on VFO B .

A Half-Wave wire antenna (made from stranded copper wire from a "big box" store) that is resonant (trimmed to the right length) at the frequency you want to operate is both fundamental and highly effective. Take a look at half wave dipole antennas in an ARRL Handbook or Antenna Book. This will get you on the air quite effectively. >I am pretty new ham and a brand new KX3/PX3 owner excited to try >my hand at DX'ing!

Each is a compromise. Now having said that, there are several antennas that come to mind. First, there is a simple dipole, fan dipole, or off center fed dipole. This assumes that you have supports, trees or equal, that can allow you to get the antenna up at least 35' and are at least 70' apart. I prefer a 40 meter off center fed dipole, OCFD, as it covers all the bands, and being off center fed, allow it to be tuned fairly easily. A simple 40 meter dipole fed in the center will work on 20, but it will require a 4:1 current balun in the system. Fan dipoles can be made to operate on both bands, but tuning is interactive. If you want to spend ~$600, a Gap Titan is a good antenna. It is a bit cumbersome to stand up, but they work. Just make sure the bottom of the antenna is about 10' above ground. This height prevents clothes lining friends and relatives, and no radials are required. There are other antennas. Each has something good or bad, price, performance, difficulty, etc. My belief is simple is best.

It is easy and quick to get up, and will serve you well until such time that you decide whether to put up a tower and beam. It will also serve well as a portable antenna.

It is quite easy to build a pair of dipoles, one for 40 and one for 20 if those are your most desirable bands. Get some wire, and some good coax and a good common mode choke for each antenna and use the ARRL handbook section on dipoles to build your own - it is not difficult. Look at what you have for antenna supports - the higher the better, but for 40 meters, 50 feet is a suggested minimum for good performance. If you have only one support that high, an inverted Vee works nicely. Use resonant dipoles center fed and feed with 50 ohm coax. Low loss RG8X is almost as low loss as RG8 but not as heavy. If you are going to run power, use the RG-8 or RG-213 right from the start. With a single tall support, for an inverted Vee configuration, position a 40 meter radiator at right angles with a 20 meter radiator and feed both with a single feedline. Being placed at right angles to each other, there is little if any interaction. Get the ends of the inverted Vee radiators up as high as possible - if you can get the ends up to the same height as the center, that is great - you will have a pair of dipoles, so much the better. Put the dipoles up, cut a bit long from what the "formula" tells you, and then trim it a bit at a time for the lowest SWR or for a reactance of zero should you have access to an antenna analyzer at the midpoint of your operating frequency. If you have room for another dipole, consider adding a multiband antenna such as a G5RV so you can explore bands other than 40 and 20. Use a good common mode choke at the antenna feedpoint (for the G5RV at the junction of the parallel feedline and the coax). You will need a tuner for a G5RV or most any other multiband antennas. If your horizontal space is limited, try a vertical. I can recommend the GAP Titan, being a halfwave vertical, it needs no radials. Mount the base 10 feet off the ground so the loop for 40 meters is above head level and use a good common mode choke at the feedpoint. This is just for starters on your antenna quest. That quest is an ongoing exercise for most hams. Do not strive for the "best" antenna for starters, just get something up in the air and start operating - with time you will be able to determine how you want to improve your antenna farm. For portable QRP operation, take a look at the End Fed Halfwave antennas offered by LNR Precision - They work and they have a good "trail friendly" lightweight version. An EFHW can be easily deployed with one end in a tree and the other end near the transmitter. If your field operations are more of the picnic table variety than the backpacking type, then consider a 32 foot heavy duty telescoping pole to hold up the center of an inverted VEE antenna. Tie the center of a dipole antenna to the top of the pole and push it up - anchor the pole to whatever vertical support is available with bungy cords. Extend the radiator ends out to whatever bushes or other supports are available. So my suggestion is to start simple with homebuilt dipoles or other wire antennas, then grow your antenna farm after you get on the air and determine what you really want, and that may be a 150 foot tower with stacked rotating beams sometime in the future. If you have space and want "beam" antennas using wire, consider 4 130 foot wires spaced 45 degrees apart (total of 180 degrees spread) and you will have V-beams that can be steered - a very effective beam on 20 meters, but does require some feedline switching to select the pair of radiators to properly direct the radiation (it is bi-directional). 73, Don W3FPR On 12/7/2015 5:13 PM, CRAIG SCHROEDER wrote: > I am pretty new ham and a brand new KX3/PX3 owner excited to try my hand at DX'ing!

Agreed - you can afford to experiment and learn a lot about antennas by building simple wire dipoles and loops before investing big money in towers and aluminum. And getting a copy of the ARRL Antenna Book, even an old edition at a swap meet or from a ham friend is highly recommended. > Put up as many as you can as big as you can.

When I got into ham radio in the 1970s I often heard the expression "if your antenna didn't fall down last winter it wasn't big enough." But that's kind of like saying "If you're driving on the highway and you don't crash you're not driving fast enough." I prefer to suggest that we should try to design and construct antennas well so that they stay up and work right. Putting a pulley and weight on the support of one end of a dipole suspended between two trees to accommodate tension changes from wind is an example of good technique. Happy antenna building Craig.

Will have some gain and the main lobes will be closer to the wire than broadside, so watch the orientation for DX coverage. I put up a G5RV at my vacation home and it loads with a tuner on 80 to 10. Has some gain on the higher bands ,keep in mind that nulls go along with the gain main lobes.

Not an uncommon occurrence - no "lawyering" required. 1/32" difference is difficult for some to discern visually - measurement may be required.

Using a 5-letter group of random letters as the practice message, then my question, in terms of Bob's approach, could be stated as follows. Which is the quickest way to achieve some target speed: to start the group at a speed where only one/two character are correct, or to start where three/four are correct? I have no doubt that with the regular and intense "concentration" that Bob advocates, any method [within common sense limits] will result in higher copying speed. That said, which starting point is going to get the operator to the target speed the quickest? I don't know. Most of the folks who can comfortably copy at speeds in excess of 30wpm seem to be from the "old school" in that many learned in the military and have been at it a very long time. I have to believe that their speed developed over time with continuous usage/practice. Nothing beats time in the saddle. An interesting "experiment" would be to take a bunch of hams who can copy at 20wpm, divide them into the two approaches being discussed and "measure" how long it takes each group to be comfortable at 30/35wpm. A human factors issue is a person's task motivation and tolerance for frustration. Starting with only one character correct out of five may be pretty daunting for some and a piece of cake for others. But, that's a separate issue. Enjoying and learning from the discussion.

Each of us has our brains "wired differently". In other words, what will work well for one person does not mean that it will work well for all. The quickest way to increasing CW speed is to get on the air and start copying stations that stretch your current copying speed. In other words, push yourself to higher speeds even if you cannot copy everything. ARRL Code Practice is good up to 35 WPM, so try that, but on the air conversations may drop you back to 25 WPM because of CW being sent imperfectly. When you can copy imperfect code (from a bug or keyer without perfect spacing), then you have 'arrived'. There is no substitute for practice - I advocate the 10 minutes a day at trying to copy above your comfortable speed limit. More time than that leads to frustration. 73, Don W3FPR On 12/7/2015 8:27 PM, Robert G Strickland wrote: > Bob's approach to increasing speed once a basic level of cw > proficiency has been achieved speak directly to my original thoughts > on the subject.

If you were buying your first HF base antenna, primarily looking for performance on 20 and 40 meters, what would you recommend? Real hams don't BUY antennas, we BUILD them. Antennas are the most important part of any station, and until you get into a tri-band beam, it is easy to build better than you can buy, and for a tiny fraction of the cost. First, BUY a copy of the ARRL Handbook and the ARRL Antenna Book. STUDY (not quick read, but STUDY) these books so that you understand how antennas work. Next, STUDY the resources at your real estate -- what's available to support one or more wires up in the air? If the answer is nothing, then consider buying a multi-band vertical. Suggestions about that later. If you can support only one point, use it to support one or two "fan" dipoles. Build one fan for 80 and 40M, and hang the center from the very top of your single support. If you have two supports widely spaced enough, hang it between them. Build a second fan dipole for 20, 15 and 10M. On these bands, 30-40 ft is a good height. Feed these antennas with 50 ohm coax. If the feedline will be much longer than about 100 ft, use RG8 to minimize feedline losses. If you're limited to a vertical, go with the biggest Cushcraft R-series you can afford, and try to mount it on your roof. HF verticals work better up in the air than on the ground. Again, feed it with 50 ohm coax, use the bigger RG8 if the feedline is very long. There are lots of practical tutorials about how to build antennas on my website. k9yc.com/publish.htm Start with the slide show and the short written piece about Antennas For Limited Space. For portable QRP use -- start with plain ordinary insulated wire. #18 - #22 is a good size. Unroll a length close to a quarter wave, toss it into a tree, using string or rope to hold it up. Unroll a second length close to a quarter wave and connect it to the chassis of the KX3. Much cheaper and works far better than so-called QRP antennas that you buy. If there are no trees around where you plan to operate, buy one of the telescoping fiberglass poles designed to hold wire antennas and tape the wire to it that you would have tossed into a tree. Connect the second wire to the chassis. There's a photo of me on my qrz.com page doing exactly this about 12 years ago at a county park near Chicago. The rig is a K2. 73, Jim K9YC > Also, what do you suggest as a high performance field antenna for QRP?

For sure, individual differences make for a big difference, both in the rate of learning and the appropriateness of any one approach. I think we all agree that "stretching your current copying speed" is the only way to get faster. That's certainly my experience. I think my curiosity comes down to how much "stretch" is the sweet spot [individual difference aside]. Lots of stretch - few characters/words copied, versus some stretch - most characters/words copied. Speaking of individual factors... I was just practicing with Rufz and noticed how long I "hang" on the first character which inevitably leads to subsequent errors. So, I pushed myself to almost "ignore" the first character and move right along. Overall error rate dropped significantly. So, yes, lots going on. Nothing beats practicing, for sure. Have a good day. ...robert On 12/8/2015 01:46, Don Wilhelm wrote: > Robert, > > What is missing is that each person learns at a different level and > pace.

Since I didn't know any better, it worked great and I worked lots of DX running 75 Watts (DC input power) on 40-80 CW. Of course, later I learned that it's a very poor antenna so I'd never use one now ;-) 73, Phil W7OX On 12/7/15 7:40 PM, Wes (N7WS) wrote: > Oh please.

My brother got his license 15 years ago. He was a music major and is a band director, all of the rigs in his shack have the side tone set to 440 Hz, A above middle C. It's been a musical tuning standard for ages. Once he got the tone of the cw being received and sent set to a standard he knows quite well his CW abilities just exploded. He moved past me like white lightning in his copy ability. He's doing 40 wpm without breaking a sweat, is net control for the Iowa 80m CW net and mastered the Vibroplex bug inside of a month. I'm coming up on my 25th year licensed. I'm an IT guy, network engineer. I've always been math/logic and mechanically inclined. I can sub-net IPV4 networks in my head. I struggled learning code. I bought both the ARRL and 73 magazine tapes. My first try on a morse exam was a flaming failure. 5 wpm test set up in a huge auditorium at the local hospital. We all sat at the front listening to a boom box...and the echo off the back wall 60' away. I locked up. I did finally learn enough to pass the 13wpm test and later the 20 but it took a lot of work. I found the Koch method and the G4FON software 10 years ago. I can now do 30 wpm comfortably, 40 in a contest. The Vibroplex bug my wife bought me still taunts and insults me. I'm much more comfortable with the single lever paddle I have and my Winkey USB.

I would want to know a few more things about your situation if I were to make any recommendations which I thought were very precise. Of the responses I read, I think the best ones (my opinion) came from Don Wilhelm and Jim Brown. Don focused on your stated preference for 40 and 20 meters, and Jim added some good advice about vertical alternatives. You didn't say exactly what flexibility you have about erecting an antenna--trees, space, etc. If you want to work DX, you need to try and get your antenna up in the air as high as possible--at least 40 ft. or more. That's particularly important if all you are able to do is run at near QRP levels with a barefoot KX3. Resonant dipoles for 40 and 20, at a decent height, should allow you to achieve some success, and they are relatively easy to construct. You don't mention if you have a tuner, or if you purchased the ATU accessory for the KX3. If you don't have either, you should probably invest in one. The KX3's internal ATU is excellent, but even a simple tuner like an MFJ, can give you several added options. One is a single dipole fed with balanced feed line, which will probably allow you to operate several other bands. When using balanced feed line and an internal ATU, a balun like the Elecraft BL-2 may be a necessary addition. That is switchable between 1:1 and 4:1, and the 1:1 setting will probably be your best option generally. This can be a very versatile arrangement, and not difficult or expensive to construct. you can erect it as a horizontal dipole or an inverted vee, depending on what you have available for supports. Several responders mentioned commercial alternatives. End Fed Half Waves, like those from PAR Electronics (now LNR) do work quite well. Some models are power limited, so choose accordingly. The Par 10/20/40 is a good choice to match the KX3, but again, you should try and get it up in the air as high as you can. Commercial multi-band verticals can be expensive, but I like Jim Brown's recommendation for something in the Cushcraft R series. I've used an R8 (and also the R7 which preceded it) for years with very good results. As Jim says, put it up off the ground if at all possible. Mine is about 15 feet above the ground, and works considerably better than when I tried it ground mounted. Some others mentioned a Gap Titan, which will give you 80 meters as well (the R8 only goes down to 40 meters), but performance on that band is very marginal! You would probably be much better off with the dipole/balanced feed line system I mention above so long as you can make the radiator part at least 100 ft. long or so. An 88 ft. version suggested by L.B. Cebik (SK), who was a highly regarded "guru" on antennas, can work very well, but will test the capabilities of your tuner on 80 meters. Also, comparing the Gap Titan to the R8 was something done quite extensively by Ward Silver, N0AX, who is well known for his expertise. Overall, the R8 was the better antenna, but it does not cover 80 meters. If you look around, you might find a good used one of either model, and save a bunch of bucks! A lot of people will tell you that nothing beats resonant dipoles. They are probably right. However, you may not be blessed with lots of space or other important aspects necessary for having such, so a single dipole and balanced line, and a good tuner, can make up for a lot of sins. The balanced feed line will help you keep your efficiency up when multi-banding so long as you have a tuner to do the matching. Using coax on such a system will introduce significant loss unless the matching is all done at the feed point. Otherwise, you might see a decent SWR, but your output will be significantly reduced. Hope you are not totally confused by all of this. Just remember that your antenna is an extremely important part of your overall system, and needs a lot of consideration and effort to really enhance your results. You have a very nice radio, but it won't do much unless you put a decent antenna on the end of it.

Ask me how I know this :-) Time in the saddle is not the nirvana for higher speed CW. Try the exercise Robert then report back. It is only 10 minutes a day. As a sideline to being a ARRL VEC, I teach morse code to new hams and hams that want to improve their CW skills. I cant take credit for this exercise. I finally took the advice from other high speed ops and found it to be the most efficient and fastest method for me in advancing my copy speed. It is necessary to spend ten minutes in quality training time a day for a few weeks. (I wouldnt call that intense, hihi) Then enjoy "time in the saddle" but do your 10 minutes regularly for awhile and see what happens. ! 73, Bob K6UJ On 12/7/15 5:27 PM, Robert G Strickland wrote: > Bob's approach to increasing speed once a basic level of cw > proficiency has been achieved speak directly to my original thoughts > on the subject.

My first antenna was a 40m dipole hung from trees with lead in run in thru an upstairs window to my radio. Actually this was in 1958 and I was 14 years old so had no money. Back in those years there was something called twin-lead which was used as feedline for TV antennas and was cheap. I made a folded-dipole and used another piece of twin lead as feedline which I soldered into a PL-259 which I connected to my three tube receiver (which I also built from a kit). Yeah that was connected wrong and it had high SWR but it received just fine. Later it worked well connected to my Heath DX-35 which could load anything. I would not know anything about SWR for a couple years but had just a lot of fun with that wire antenna. It was probably 15 to 25 foot off the ground and put up with something called "clothesline". Back in those years people hung their clothes outside in the sun to dry attached to clothesline with something called clothes pins. OH well, that is how I, a pretty ignorant 8th grader, started out in ham radio on 40m (and it would also work on 15m). It received all bands pretty well. 10m AM in 1958 was something to have experienced. No one will every see conditions like that sunspot maximum again (well for a couple hundred years, anyway).

If I had no limitations, financial or regulatory, I would probably get a large Steppir beam on a tower at least 70' tall. But that is probably not what you are thinking of. A simple, cheap antenna is a dipole up as high as possible -- no less than 30 feet in the air at the center, preferably higher. You could simply make a 'fan dipole' for 40 and 20 meters, fed with coax and a 1:1 balun at the feedpoint. An even better antenna is a 40 or 80 meter dipole fed with open wire line (see ). You can buy this assembled quite reasonably. It will work with the KX3 internal tuner plus a 1:1 or 4:1 balun at the transceiver. If the feedline is at least 33 feet long, a 66-foot dipole will work on all bands from 80 through 10 meters (probably 6 meters too). Again, the higher the better. You can buy all kinds of expensive verticals and clever compact antennas, but the above will outperform all of them for both DX and local work. Some of the expensive ones will be far worse. The only better antenna is a directional antenna like a rotary beam. I'll let someone else answer your question about field antennas. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 8 Dec 2015 00:13, CRAIG SCHROEDER wrote: > I am pretty new ham and a brand new KX3/PX3 owner excited to try my > hand at DX'ing!

What does that mean? Please, don't take my comment seriously. It was tongue in cheek. There is one installed here serving a remote Elecraft station. On at least one band, 17 meters, and one simple test, the Steppir at 45 feet beats the Buckmaster by 30 db! Other bands, different results. The Buckmaster never wins compared to inverted vees though, but it DOES tune up on multiple bands. It and the Elecraft tuner get along fine, so it serves its purpose (which is NOT high performance).

Thus, you're either going to need to get a high gain antenna, e.g. tower and beam, or I would suggest digital modes. I've had a lot of success with WAS using JT65, JT9, PSK and RTTY using 10W or below with modest wire antennas. As many have suggested either wire dipoles, OCFD or G5RV all have there advantages and disadvantages. I'm currently using a RadioWavz FD40-3 fan dipole resonant on 40, 20 and 10m - for $56 this is a very cost effective and nicely built purchase and will get you on the air quickly while you consider other options. I've built many wire and yagi HF antennas, and whether you build or buy you're going to need an antenna analyzer to tune the antenna. I personally use a RigExperts AA-54, which I like a lot. Thus my suggestion to get going would be RadioWavz FD40-3 and a RigExperts AA-54 or similar.

When you're starting out is suggest keeping it simple and cheap. Get on the air and improve things as you gain knowledge and skills to best analyze your QTH and finances. A properly installed dipole can work the world. An OCF dipole design just allows impedance matching on multiple bands, but, it's primarily resonant on one band. You can achieve the same effect with a dipole cut for the lowest band you wish to work; fed with ladder line and a tuner, get the antenna as high as you reasonably can. Worry with towers, verticals, ...etc later after you've had time to enjoy the hobby. You can work the world literally with just a simple wire antenna. Personally I use the Buckmaster ocf 7 bands antenna broadside to Europe.

You can use the command line or an app called "Grig" (no doubt others too) to test Hamlib. 73.

Consider yourself (in a kindly way of course) doubly dunned.] To Larry and all other fellow noise sufferers equipped with K3/K3S transceivers... Short Version: See if the AM BC crud goes away when the NB LEVEL has IF set to OFF. The crud is a necessary possible artifact of IF blanking in the K3/K3S. This "IF" process in the K3/K3S is at root the same as 1950's noise blanking in tube gear, but with modern improvements. Long Version: The K3 or K3S (referred to as K3 in the rest of the post) has two separate noise blanker processes: IF and DSP. Depending on settings with a hold on the single NB button [LEVEL] you can have none, just IF, just DSP, or both processes running. If they are both on, they work in series. The IF NB works first, in broadband circuits before the roofing filters. The DSP NB works second, after the RX low IF analog to digital conversion. The DSP NB has algorithms doing its magic, and is buried in the number soup that is SDR. The IF NB is basically the same NB in the tube ham receivers I used as a teenager. A strong pulse is detected early in the RX string, and is used to cut off the incoming broadband signal for the duration of the pulse. There are refinements to that process, but at root blanking cuts off some part of the RF/IF string for the duration of the noise pulse. It is possible for the RF peaks of non-noise signals to trip the blanking threshold. The modern, mostly digital K3 still uses the ancient IF blanking because it still works for certain kinds of noise. Usefully, by messing with preamp/attenuator settings and the width and delay of the blank, the oldie but goodie blanking can be "tuned" to better blank certain kinds of noise. We get to "tinker" with the NB and discover the best setting for a certain kind of noise. But the IF NB still has inescapable aspects of blanking, drawbacks when I was a teen and the same now: modulating the RF or pre-filter IF with the blanking pulse, and MUST have sidebands and intermodulation from the process. Some of those artifacts of blanking will sound like chewed up signals that are NOT in the passband. This is because the blanking pulse has to be applied in a broadband place where the noise pulses are still extremely sharp and narrow. Anything loud making it through the front end bandpass filters can be in the NB IF process blanking artifacts. On 160 meters that easily involves strong local AM broadcast. In CW contests with many strong CW signals around the band, you can hear beeple bopple from intermodulating CW signals or crud from "spread out" QRN. The thinking? The crud, while possibly irritating, is far less of a problem than the line or spark noise that is being blocked. The K3 IF blocking does have sophisticated amenities added to the RF/IF blanking which improve on the old tube type versions which generally were either just on or off with no adjustments. I have found that a pernicious recurring line noise on 160 around my QTH is well dealt with using NB, IF set to narrow-3 and DSP to 1-7 or 2-7. This will produce a variation in effectiveness with frequency, usually with a noise null or two somewhere in the CW frequencies 5-10 kHz wide. The overall noise drop in these nulls is 5, 6, 7 S units, dropping down to the level of regular band noise without the buzz. There will be some blanker trash that comes and goes, but I am rescued from giving up on copying anything not S9 or louder and am able to operate the contest at 93% or so, placing my run frequencies in the K3 NB noise null. To those trying to get rid of a certain noise, remember that there are 21+21+(21x21) combinations of IF and DSP blanking. That's 483 combinations, not counting variations with preamp/normal/atten settings. Hope this has been helpful. 73, Guy K2AV On Tue, Dec 8, 2015 at 10:56 AM, Larry - K1UO wrote: > Hello all..

I also encountered occasional noise on 160, (neighborhood Christmas decorations!)?during last weekends contest as well. I found similar settings worked as you have described below. In addition, I found that switching in the notch filter and manually adjusting the notch frequency just a couple hundred hertz plus or minus from my CW offset of 600hz, and adding in some NR, I could reduce a bit more of the hash from the NB. I?was typically listening on the 250hz roofing filter and narrowed it down with DSP to 200hz. Point being, lots of?flexibility in adjustments to?kill much of the unwanted hash. ? ?73 Gene, N9TF ?

I got the distinct impression that it's never going to anything useful. For several years, I've been in line to buy N8LP's new LP500 TX monitor. It WILL do a LOT of useful stuff, and is due to go into production in the first half of 2016. A year or so ago, I bought a used LP100A from the estate of a local SK. It came with one coupler and I bought a second for my SO2R station. The LP100A auto-switches between them. I love it! As a result, I can run much closer to our 1,5000 W limit than with the less accurate power meters I used before. 73, Jim K9YC From john at kk9a.com Wed Dec 9 13:46:12 2015 From: john at kk9a.com (john at kk9a.com) Date: Wed, 9 Dec 2015 13:46:12 -0500 Subject: [Elecraft] P3 transmit monitor Message-ID: <906244722c82da8bbed21e1bbbe11ecc.squirrel@www11.qth.com> The LP100A is an excellent watt meter and N8LP offers great support.

Comments regarding the KX3 Noise blanker: It is effective for some kinds of power line noise and ignition noise, I normally leave it on at a setting of 6. It is not effective at all with heavy rain or snow static.? By way of comparison I have an SDRPlay dongle connected to the same transverter and using the HDSDR software can enable the RF noise blanker in that software and it can reduce an S9+20 rain static noise that masks all signals to almost zero and allows me to decode a distant weak CW beacon that is just above the noise floor. On the KX3, just S9+ noise no matter what setting used on the NB. I wonder if the DSP noise blanking could be improved in the KX3 to blank such heavy static? Does the KX3 noise blanker work in the demodulated audio or the RF domain?

Message-ID: "The Buckmaster never wins compared to inverted vees though, but it DOES tune up on multiple bands. It and the Elecraft tuner get along fine, so it serves its purpose (which is NOT high performance)." Whaaaaaaaaaaaaaaa????????? The Buckmaster is recommended to be installed as an inverted V. That's sweet that the E Tuner gets along with it but I have the 3,000w version and run full legal limit on all bands (where allowed) that it operates on without the need to use my tuner. Not high performance eh? Funny stuff. I suggest anyone considering this fine antenna consult the eHam reviews of it by people who actually own the antenna & have experience with it.

For that, I set the top of the display for maximum averaging, and I set the waterfall as slow as it will go. I set the display height to 24 dB for day to day operation, and 42 dB in contests (and DX pileups). I set the bottom of the display so that an empty channel shows up as tiny flecks of noise. I ALWAYS operate in Fixed Tune Mode, so that display averaging continues to accumulate as I tune across the band. When you do all of these things, random band noise goes away (it averages out to zero) so you're left with signals and coherent noise (like switching power supplies). Set the display width depending on what you're doing at the time. For example, to monitor a quiet band for activity, I typically set for 100 kHz or 200 kHz. In a contest, I'll set it for the width of activity for that contest. For a DX pileup, I go about twice as wide as the pileup, with the DX at one end. It can also be quite useful to assign commonly used settings to the soft-keys. I assign the Fixed Tune Toggle, the Peak/Average Toggle, and the display widths that I most often used. For the P3 that I use for spectrum measurements, I also assign the Capture to RAM command. 73, Jim K9YC From steven4lq at gmail.com Wed Dec 9 19:42:28 2015 From: steven4lq at gmail.com (Steve Ellington) Date: Wed, 9 Dec 2015 19:42:28 -0500 Subject: [Elecraft] P3 cw waterfall In-Reply-To: References: Message-ID: The P3 can't compete with a computer but it is handy. n4lq On Wed, Dec 9, 2015 at 4:10 PM, Barry N1EU wrote: > Is the waterfall speed adjustable? > > Any brilliant insights on optimal cw waterfall setup gratefully > appreciated!

Can you explain "averages to zero"? I would think that random noise would average to something non-zero and then be comparitively reduced by the averaging interval, and thus more like the normal noise level over sqrt(N). Perhaps this is then reliably below the threshold for any color to appear, which would make it effectively zero. (I have only used a P3 once, at field day, so I may be confused.) 73 de n1dam From rcrgs at verizon.net Wed Dec 9 20:13:50 2015 From: rcrgs at verizon.net (Robert G Strickland) Date: Thu, 10 Dec 2015 01:13:50 +0000 Subject: [Elecraft] Fwd: Re: [OT] increasing CW copy speed: practice slow -v- practice fast In-Reply-To: <5666656C.3090106@pacbell.net> References: <566393CB.5000109@pacbell.net> <5663EB10.5040804@pacbell.net> <56663204.80008@verizon.net> <5666656C.3090106@pacbell.net> Message-ID: <5668D1CE.6090306@verizon.net> Bob... Yes, I have used your comments to infuse a new energy into the business of "speeding up." At the moment, still using 5-letter groups and Rufz, I start with the "dot" letters, e/h/i/s with U & V, at around 20wpm and spends several trial at that task. Then, the full alphabet at 30wpm with the previously mentioned "ignoring the first letter." As you no doubt expect, the 5-ltr groups at 30wpm are going better. I increase the speed one ltr/min per trial up to around 35wpm at which point there are more mistakes. Then, I drop back to 30wpm and start the process over again. I do as many sequences as can comfortably fit into your 10min window. It's fun, and I imagine that speed is picking up. Thanks for your contributions to the discussion. Again, thanks to Elecraft for making space for this thread. ...robert On 12/8/2015 05:06, Robert Harmon wrote: > Robert, > > Human nature being what it is all of us put what we think is beneficial > "time in the saddle" > on the air but we become complacent and migrate back to easier copy and > we are kidding > ourselves and not really exercising our copying speed abilities.

In-Reply-To: References: Message-ID: <5668D879.7050907@subich.com> Off-center fed dipoles are a compromise at best. They will never be any better than a simple half wave dipole for the current band and a multi-band fan or trapped fan dipole generally provides a better match without complex and failure prone matching networks. A well designed multi-band fan or fan of trapped dipoles is easy for the user to build and erect for much less $$ than the Buckmaster. The only "benefit" of commercial OCF antennas is that they separate the inexperienced and unsophisticated from their cash. I've run 100W and wire antennas for more than 15 years ... in that time I've tried both OCF vs. tapped inverted Vs vs. multi-band fan antennas vs. G5RV type antennas. The multi-band fan is more efficient and less noisy quieter than any of the OCF or G5RV type antennas. For simple antennas, K9YC is correct ... use a multi-band fan for 80, 40 and 30 meters and the largest Cushcraft R-series vertical you can afford/install *on the roof* for [40/30]/20/17/15/12/10/6. When you get some experience and are ready to spend real money, install a tower and a good yagi (or yagis) for 20-6 meters. My dipoles and verticals have been enough to place 2nd worldwide in the low power/simple antenna class of CQ's DX Marathon for the last several years ... plus land me on the DXCC Honor Roll both CW and Mixed as well as rack up more than 2500 countries on DXCC Challenge. 73, ...

Add resistance. This is usually not a good idea, but works for military and diplomatic sites where they can just crank up the power. 2. Lower the Q, usually with fatter conductors. Search for ?cage dipole? for examples. Also used at VHF and UHF. Loading coils are high-Q, so reduce the bandwidth of an antenna. 3. Parallel elements resonant at close frequencies. These can be driven, like in a log periodic, or passive. From looking at pictures, the Gap Titan appears to use passive elements. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 9, 2015, at 6:00 PM, Charlie T, K3ICH wrote: > > I forget the name of it, (MAX-something) but there was an "antenna" produced back in the 70's that consisted of a sealed center box with a coax connector on the bottom and two eyes to attach dipole wires.

Fortunately, when they arrived with our gear, the guys in the Philippines had already adjusted and marked them. I wonder sometimes why coupled-resonator dipole haven't caught on in the ham community. I've built several, the first when the WARC HF bands opened. They're cheap, easy to build, and extremely easy to adjust, and they're "a half-wave dipole" on every band with a predictable pattern and balanced feed. I've never done more than 3 bands, but I've heard in the past [anecdotally] doing 5 using those old crossed spacers designed for cage elements. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/9/2015 6:10 PM, Ken G Kopp wrote: > The B & W antenna was/is a T2FD.

If you already have a good wattmeter, you don't need it. If you don't, the positive thing is that the wattmeter works just fine, and saves you from yet another box to put on your bench. So it does have value in a compact K-Line station. The waveform display can be replicated simply by using your bench O'Scope and an 18 inch long piece of wire. I expected more functionality from the P3 TX MON within the P3 hardware which Is, in essence, an SDR. What I thought I was getting was a pseudo Spectrum Analysis tool with a waveform similar to what you get if you unplug the P3 from the Serial Cable and use IF bleed through to see your transmitter spectrum and a RTTY cross pulse ellipsoid display, like my old Heath SB620 had. But after a three year wait to purchase and a two and a half month wait for delivery after ordering one last Dayton, all I got for my money was yet another wattmeter. And I already had plenty of those. The waveforms are cute and non-ham visitors to the shack think they are keen, especially an 8 year old that was amazed to watch his voice become green squiggly lines on the P3 screen during Kid's Day. As far as daily functionality, not so much. For signal testing for station maintenance? My O'Scope is infinitely more adjustable and can even compare audio in to RF out waveforms (dual trace). If this board had included the keyboard USB input for those of us who don't need the external VGA functionality, I would be less inclined to complain. As it is, for me, it was a useless expenditure as it does nothing at my station that I could not already do with existing equipment.

Simple dipoles or fan dipole for the desired bands is a much better option.

The Buckmaster is recommended to be installed as an inverted V. That's sweet that the E Tuner gets along with it but I have the 3,000w version and run full legal limit on all bands (where allowed) that it operates on without the need to use my tuner. Not high performance eh? Funny stuff. I suggest anyone considering this fine antenna consult the eHam reviews of it by people who actually own the antenna & have experience with it. Comparing a beam antenna to a wire is sort of ridiculous IMO for what should be more than obvious reasons.

It replaced my bench scope which took-up too much space on my desk and relegated to a corner and integrated the power meter/VSWR into one display. Now my P3 is on a shelf in front of me and in my field of view when transmitting. The SVGA is below on the desk top. I do like having the confidence of seeing my modulation envelop. Takes me back to the days of broadcast AM In Tampa in the 60s. I too would have liked to have a spectrum display as well, but knew when ordering it was not too be! Hopefully someday Elecraft will create such a product; but I doubt it will be anywhere in the price range of the Transmit Monitor. I'll give change for my $0.02. 73 George AI4VZ From lists at subich.com Thu Dec 10 08:41:52 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Thu, 10 Dec 2015 08:41:52 -0500 Subject: [Elecraft] OT: B & W antenna In-Reply-To: <1449728413.6805.32.camel@nostromo> References: <5668EECA.8050200@foothill.net> <1449728413.6805.32.camel@nostromo> Message-ID: <56698120.1010204@subich.com> > I have heard several stories about what it has for a resistor on it, > if anyone knows for sure, I would be most interested. https://en.wikipedia.org/wiki/T2FD_antenna 73, ...

That is what a dummy load is after all - great SWR but the losses are huge. I built a T2FD when I was newly licensed back in 1984 (when I didn?t know any better), from an article in Practical Wireless. I used the specified resistor and built it according to spec, and put it on top of a 220 ft building, raised 20 ft above the building. Any antenna should have worked really well at this height being totally up in the clear. The SWR was great across all the bands, but I was very disappointed in it?s performance. I have learnt a lot since then? BTW nothing wrong with OCFD antennas, they work well on their harmonic frequencies as a multi band antenna, provided they are installed properly, and a good CMC is used in the feedline. No, not an ugly Balun which might give you 1000 - 1500 ohms choking impedance if you?re lucky, but a proper CMC with more than 12 000 ohms choking impedance. I would rather hang a good OCFD with a quality 4:1 Balun at the feed point, and a quality CMC choke for 80 - 10 just before the coax enters the house, rather than fiddle with 8 dipoles yuck? Better yet, would be to use an EFHW 80-10 1K built by www.myantennas.com 73 John, ZS5J On 10 Dec 2015, at 3:41 PM, Joe Subich, W4TV wrote: > I have heard several stories about what it has for a resistor on it, > if anyone knows for sure, I would be most interested. https://en.wikipedia.org/wiki/T2FD_antenna 73, ...

As a user of an 80M OCF dipole, I knew it was going to be a compromise. My goal was to be able to put up an antenna on a small lot that would get me on the air on 80 and 40. I don't have room to run even a full 1/2 wave dipole for 80m, or a lot of wires,?but the OCF dimensions (45'/90') fit in to my lot with a bit of zig-zagging. I don't use the OCF on anything higher than 40m as I have a small beam for the higher bands. Yes, common mode current can be a problem if not designed properly. I use a 4:1 current balun and an additional 10 turn choke at the feed point, in addition to a single point ground system. No issues at this location. I agree simple dipoles or fan dipoles would be desired. In my case, I do not have 66' in both directions, of the direction of interest, to string a full size 80m dipole. But I can get 45' in one direction and the 90' leg does take a turn at 75'. Point is, we put up what we can, understanding the compromises (antenna theory) in the space we have. ? One point of?relative (A/B)?comparison I can share?. The 80m?OFC is resonate of course on?17 and 12 meters. I have a rotatable?trap dipole (D3W) on the tower for 12/17/30m at 42'. The OFC is at 35'. When comparing signal strength of the two antennas to EU, which is where the OFC is broad side to on 17m, the OFC is about 20DB less signal strength than the rotatable trap?dipole. So yes, the OCF is a compromise. ? There has been one benefit to the OCF in contesting, and that is in the NAQP and SS contest. With it's height above ground at only 35', it works well for close in state side contacts on 20/40/80. It comes down to what the operators goals are, and understanding antenna theory. ? 73 Gene N9TF ----- Original Message ----- From: john at kk9a.com To: elecraft at mailman.qth.net Sent: Thursday, December 10, 2015 7:16:30 AM Subject: Re: [Elecraft] Rick & antennas...

The Buckmaster is recommended to be installed as an inverted V. That's sweet that the E Tuner gets along with it but I have the 3,000w version and run full legal limit on all bands (where allowed) that it operates on without the need to use my tuner. Not high performance eh? Funny stuff. I suggest anyone considering this fine antenna consult the ?eHam reviews of it by people who actually own the antenna & have experience with it. Comparing a beam antenna to a wire is sort of ridiculous IMO for what should be more than obvious reasons. Lotsa haters out there as usual. kd0bcf ______________________________________________________________ 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 n9tf at comcast.net From fcady at montana.edu Thu Dec 10 11:26:43 2015 From: fcady at montana.edu (Cady, Fred) Date: Thu, 10 Dec 2015 16:26:43 +0000 Subject: [Elecraft] P3 cw waterfall In-Reply-To: References: <5668CA7C.70802@audiosystemsgroup.com> <53090.71.74.118.201.1449723323.squirrel@mail.expedient.net> <56690E78.2090202@kc9wsj.us>, Message-ID: The Refresh rate in the P3 menu changes the speed of the waterfall only in Fixed-Tune mode, not in Tracking mode.

I had a similar issue on my Chicago city lot. My solution was a loaded dipole for 80M that also resonated on 40M. You can buy antennas like this here. http://www.hypowerantenna.com/products/dipoles Look at the 2B4080L As others have noted, the major advantages are 1) predictable pattern 2) fed with coax, so they can be choked to kill common mode feedline current. Common mode feedline current makes a noisy antenna and puts RF in the shack. I've used the 160/80 M version of this antenna very successfully in three locations, adding a 40M fan element to cover that band. Barry's antennas are well designed, but their construction is a bit light weight for high stress applications (like 150 ft up in tall trees that sway in the wind). They're fine for lower stress installations. For the antennas I've built based on his designs, I've bought the loading coils and built the rest. His standard design was more than strong enough for my Chicago installation at about 40 ft between fixed points (not trees). 73, Jim K9YC From idarack at gmail.com Thu Dec 10 12:39:34 2015 From: idarack at gmail.com (Irwin Darack) Date: Thu, 10 Dec 2015 12:39:34 -0500 Subject: [Elecraft] OT looking for K3EZ utility In-Reply-To: <000a01d1335b$25824570$7086d050$@kh-translation.dk> References: <000a01d1335b$25824570$7086d050$@kh-translation.dk> Message-ID: Great Utility that I routinely use to check Config and Menu settings.

I'm having a similar problem with data modes and the sub receiver. Here's an example using a strong CW signal as an example to make it easy to hear: 1. Tune in a strong CW with the subRX off. 2. Press the A/B button twice to copy all info to the subRX 3. Turn on the subRX (tap SUB) At this point you will hear the main RX in the left speaker, the subRX in the right - as expected. It truly is the subRX audio as you can tune it and the right channel follows the tuning. Now: 4. Change mode to DATA. The result of this is you will hear the CW signal in the left channel change pitch but the CW signal in the right channel will remain unchanged - again as expected. 5. Press the A/B button twice to copy all info the subRX (the only thing changing should be the mode) Result: The audio remains unchanged in the left channel but the right channel goes dead. - NOT EXPECTED! If I change the mode back to CW, then double tap the A/B button everything returns to normal. MainRX in left channel and subRX in the right. This makes operating split in RTTY and trying to listen to the callers impossible. Perhaps this is by design? No logging software or K3 utility connected at the time, the K3 port is closed.

My novice antenna was an 80/40 fan dipole with the 80m legs bent back about 135 degrees. I feel that an antenna with full length elements, even if the ends are bent back, will perform better than one that uses loading coils. The reason I say this is that, when you have a full half wave antenna, most of the radiation comes from the high current center half of the antenna. The ends do not radiate nearly as much as the center portion. Ken WA8JXM On 12/10/15 12:38 PM, Jim Brown wrote: > > I had a similar issue on my Chicago city lot.

I just made a RTTY contact with HH2/N5JR using the dual RTTY function.

As I understand it a rhombic uses a resistor, and sometimes works quite well. On 160 I have an OCFD 1/2 wavelength that is goes from one side of the end of a very small canyon to the other. The net result is that the center of the antenna is about 80 feet above ground, the ends are only 50 ft above ground. On flat ground this would be a NVIS antenna being so low; however, with the ground 100 feet to the west at the same height as the antenna and the ground 100 feet to the east being 300 feet below the antenna I suspect the pattern looks more like a beam pointing east. Considering I have broken two important rules, the antenna is OCFD, and is on average it is well under 1/2 wavelength above ground it is amazing I can work the east so well. 73 Brian KF6C From k6dgw at foothill.net Thu Dec 10 19:32:34 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 10 Dec 2015 16:32:34 -0800 Subject: [Elecraft] P3 cw waterfall In-Reply-To: References: <5668CA7C.70802@audiosystemsgroup.com> <53090.71.74.118.201.1449723323.squirrel@mail.expedient.net> <56690E78.2090202@kc9wsj.us> <60615.71.74.118.201.1449761398.squirrel@mail.expedient.net> Message-ID: <566A19A2.7070805@foothill.net> I remember slowing it down when I first got my P3 but with it currently sitting on the shelf, I can't go experiment.

Other than those, I find the Elecraft factory options tend to work very well. I think one complication is that the SVGA option complicates the operation a little and there are things that work in the P3 display but not in the SVGA and vice versa. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/10/2015 3:08 PM, Barry N1EU wrote: > Sorry for my dimness, but I've tried Tracking mode and Fixed-Tune > mode, varying the "update rate" and "refresh rate" and I still am not > seeing a change in the waterfall speed.

I have noticed that I am flat topping on voice peaks which is a reminder that I need to turn the power down on the K3 to the ALS-600. I find the PEP wattmeter and SWR display useful. Yes, it compressed the FFT and waterfall some, but it was a trade-off that is now "normal". I am satisfied with it and have it enabled at all times. While I wish the TX monitor could also show an FFT of the transmission, I understand this is not possible. At least this way I am able to monitor my TX signal at the output of the amplifier. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

In-Reply-To: <005701d133a8$e44a1e40$acde5ac0$@com> Message-ID: Brian, Be careful of your logic. The reason a rhombic works so well is that most rhombics are 2 or more wavelengths long per leg. However, putting in a resister makes the beast directional toward the resister, not all bad nor inefficient. But the T2FD type antenna is only a 1/2 wave long on the lowest frequency making it more efficient as you go up toward 10 meters. I have been reading a lot of comments on antennas here, some are correct and some just may be close at best. Let me reiterate something I've said earlier and regularly. There is NO perfect antenna. Every one is some compromise in one way or another. in my case, I need to deal with 40 meter space with a desire to use 80 meters. So, part of my horizontal antenna is bent down toward the ground. It fits. Do I have the best antenna?? No. But, it does fit. OCFD antennas are not really bad antennas if you follow the rules of horizontal antennas. If the antenna was fed in the center, it would be 50 Ohms or nearly so at its 1/2 wave length. Above that, even multiples of the 1/2 wave frequency, the feed impedance would be very high. So, it was figured out that you can feed off center and could find a spot that would not be awful at the even harmonics. A 4:1 current balun will take of most of the impedance issue and bring it down into range of your tuner. A good balun will have a loss of less than 1 db. If you use good, low loss coax, losses will not be bad. The 1/2 wave dipole, center fed dipole. fed with open wire and a balun at the shack entrance makes a good antenna, and the losses may be a slight amount lower than the OCFD, but it follows the rules of horizontal antennas that are a specific height. There is nothing in ham radio that is argued more passionately than antennas, with maybe the differences between Windows and the Apple OS. 73, Barry K3NDM ------ Original Message ------ From: "Brian D.

Ummm ... rhombics *always* work well for their intended use. Unterminated, they are bi-directional. With the terminating resistor, they are unidirectional in the direction from the feedline to the terminator. Since terminated rhombics are usually 2 or more wavelengths on a side, they have very narrow beamwidths with a big F/B ratio, low radiation angle, and high gain. They were used on point-to-point HF circuits in the 30's through maybe the 60's or so. I worked coastal marine in 56-57. We generally used V-beams with wider beamwidths since our targets were ships that moved around, but we had a couple of rhombics, one aimed at NMO in Hawaii. Tap the key at 5 KW and they told us we were QSA 11R5:-) OCF's can serve well in the right situations and with the right precautions to mitigate the downsides. The infamous B&W folded dipole was never billed as anything other than what it was ... an antenna with a non-inductive resistance that pretty much swamped any effects from the antenna, and could be used 3 - 30 MHz, in the right situations. Tom Schiller, N6BT, likes to show his "illuminator", a 300 W light bulb fed through a common mode choke. He even put three up as a "phased array. Any RF in any conductor will radiate. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org From ron at cobi.biz Thu Dec 10 23:43:04 2015 From: ron at cobi.biz (Ron D'Eau Claire) Date: Thu, 10 Dec 2015 20:43:04 -0800 Subject: [Elecraft] Antennas with resistor and OCFD.

Instead, the resistor absorbed the RF that would have been radiated on (or received from) the reciprocal heading, giving the array its unidirectional characteristic. Yagi's, quads and similar arrays gain a stronger main lobe by suppressing radiation in other directions. A rhombic is a classic example of how the best design is not always the design that radiates the most RF. The problem with a rhombic for Ham use on the HF bands is that they tend to be an absolute beast to try to rotate. 73, Ron AC7AC From n1eu.barry at gmail.com Fri Dec 11 05:25:09 2015 From: n1eu.barry at gmail.com (Barry N1EU) Date: Fri, 11 Dec 2015 05:25:09 -0500 Subject: [Elecraft] P3 transmit monitor In-Reply-To: <20151211013050.GC3518@n0nb.us> References: <20151211013050.GC3518@n0nb.us> Message-ID: Can you get a relative assessment of the degree of compression (speech processing) by viewing the ssb waveform in the P3 TX monitor?

The Christmas tree definitely gets more distorted on the display as the compression is increased. Just now as I adjust it up and down while speaking into a dummy load the compression is quite apparent as the control hits 13 and above with the MC-60 mic. I typically leave COMP at 10 so it's not quite as noticeable on the display. Sometimes on 75m I have RFI get into the MC-60 (I've done the mods which helped but not totally eliminated it). With the TX mon I see it right away if I have the audio monitor turned down too low as I can hear a motorboating sound when it happens. It's quite apparent on the display. Could I live without the TX monitor? Yes. Is it a nice station accessory? Yes. Is it on a par with having a quality scope or spectrum analyzer? No. Does a scope give continuous feedback on PEP forward power and SWR? No. Do I plan to sell it? No. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

Ahead of the DSP are the mixer and its duplexer, which have a finite bandwidth, and possibly the roofing filters, which have much narrower bandwidths. Because of this, there's no way for the DSP to gain access to wideband data for blanking purposes. While this does reduced effectiveness on some types of noise, the blanker still works well on most. I use it every day at my QTH on noise ranging from telephone-pole ESD to appliances and computer peripherals. And because the blanker is strictly operating within a narrow bandwidth, it cannot easily be "pumped" by signals well outside the IF passband. The KX3's narrowband filtering also gives it a big advantage in blocking dynamic range compared to other SDRs that have nearly unlimited input bandwidth. For example, Sherwood measured the KX3's BDR at 138 dB, compared to something in the low to mid 120's for "pure" SDRs. The KX3 is also fifth on Sherwood's list for 2-kHz IMDDR3, again because of the narrow roofing filter. Since the DSP controls blanking, it may be possible to implement additional noise blanking algorithms in the future. That is definitely on our list. If you send us a detailed description of the types of noise you encounter, we could try to duplicate them in the lab during this effort. 73, Wayne N6KR On Dec 11, 2015, at 3:59 AM, David Anderson wrote: > Still interested in any comments about how the KX3 noise blanker is implemented, and if it could be improved to make it as effective as the wide band RF blanker in HDSDR. > > I now have the SDRPlay tracking the KX3 VFO so that in the event of static rain QRN I can switch to the SDRPlay for good copy when the KX3 is useless. > > 73 from David GM4JJJ > >> On 9 Dec 2015, at 20:30, wrote: >> >> I use my KX3 on 144 MHz (with external transverter). >> >> Comments regarding the KX3 Noise blanker: >> >> It is effective for some kinds of power line noise and ignition noise, I normally leave it on at a setting of 6. >> >> It is not effective at all with heavy rain or snow static. >> >> By way of comparison I have an SDRPlay dongle connected to the same transverter and using the HDSDR software can enable the RF noise blanker in that software and it can reduce an S9+20 rain static noise that masks all signals to almost zero and allows me to decode a distant weak CW beacon that is just above the noise floor.

Band stacking, memories, equalizers, info about settings, general configuration, RX configuration, TX configuration, AGC setup, a command utility, scanning of a band measuring SWR every 10 kHz (as I remember) plus setup for the K3 EZ itself. All very handy. It depends on your needs which of the functions you will be using.

The file naming is interesting, as the K3 was introduced at Visalia in 2007, I think. The developer, W2BC, was in declining health, and I see the call has been reassigned, so I assume he's a SK. I corresponded with him several times, and he was cordial and helpful. You can save screenshots of each screen after you scan the radio for each one. I use a microKEYER II with my K3 but have an A/B switch to bypass the MKII and connect the K3 directly to a serial port (actually a Gearmo USB adapter) when using this program or the K3 Utility program. 73, Jim N7US -----Original Message----- Thanks to Mark, WB9CIF, I've got the last three releases of K3_EZ available here: http://files.kc9wsj.us/~jschmidt/K3_EZ/ -- Jeff, KC9WSJ EN52wf From mikefurrey at att.net Fri Dec 11 12:39:13 2015 From: mikefurrey at att.net (Mike Furrey) Date: Fri, 11 Dec 2015 17:39:13 +0000 (UTC) Subject: [Elecraft] w4rnl (sk) and antennas In-Reply-To: <566B000F.1000102@audiosystemsgroup.com> References: <566B000F.1000102@audiosystemsgroup.com> Message-ID: <1872034647.949486.1449855553074.JavaMail.yahoo@mail.yahoo.com> As Jim mentions, this is a good article worth saving and it includes one of my favorite and often used antenna, the 20 meter EDZ - 86 feet long. I have also used this antenna on bands above 20 meters and on 10 it produces a nice clover-leaf pattern with gain. I had two of these at right angles to each other at a school I taught at. As for using it with the K3 ... I installed the internal tuner and at the output I attached a 4:1 balun. Some bands the K3 could not find a suitable match and I solved that by adjusting the length of the 450 ohm ladder line going to the antenna (can't remember the length). In another case I obtained a match by changing the length of RG8 between the K3 and the balun. In an apartment in FL I used the antenna in a stealth manor, 43 feet 18 gauge insulated green wire suspended from the limb of a tree outside my unit and 43 feet horizontal, hid in the same big tree. It worked very nicely. (Maybe I should write up the antenna I used on 160 in the SP test from that apartment.) For NAQP I built a 10 meter EDZ and suspended the entire antenna vertically and that also worked nicely.? 73, Mike WA5POK On Friday, December 11, 2015 10:57 AM, Jim Brown wrote: On Fri,12/11/2015 7:50 AM, Anthony Scandurra wrote: > You can find it here: > > http://www.qsl.net/v73ns/backyardwireantennaes.pdf Lots of great ideas here. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to mikefurrey at att.net From gm4jjj at yahoo.co.uk Fri Dec 11 13:55:22 2015 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Fri, 11 Dec 2015 18:55:22 +0000 Subject: [Elecraft] [KX3] Noise blanker comments In-Reply-To: References: <2F281D902E10CABD.1DBA5D3C-CFDC-488B-B062-7FF28B35587B@mail.outlook.com> <8706A9DE-DB68-42C4-8431-3551474A3135@yahoo.co.uk> Message-ID: <42AADEF2-E86C-47DA-A05A-21FAC480666F@yahoo.co.uk> Wayne, Many thanks for the comprehensive reply. Next time I encounter the static rain/snow that completely overwhelmed the KX3 noise blanker, I will make a short wide band RF recording from the SDR and can send you a link to the file which may help with developing other DSP noise blanking algorithms. I do agree the existing KX3 noise blanker does a great job on other types of pulse noises, and doesn't suffer much when used in the presence of other strong signals on the band. Much much better in that respect than my previous transceivers. For now I am happy to use the KX3 in tandem with the wide band SDR when I need to blank out the rain static on 144 MHz which happens from time to time. 73 from David GM4JJJ > On 11 Dec 2015, at 15:48, Wayne Burdick wrote: > > David, > > The KX3's noise blanker is implemented entirely within its DSP.

I discovered last night that I have the following situation. When in SSB mode on 160 Meters and the 2nd RX is turned on, the SSB signals are on the same frequency. When I invoke the diversity mode, the 2nd RX is receiving at 1.5 kHz higher. I tested this on numerous signals and at various frequencies; always the same. In the CW mode the problem does not exist. In diversity mode the CW signals in both RXs are on the same frequency. Anyone with an idea of what is happening here. I do not remember this happening before. RIT is off. I did not try other bands as I normally do not operate on other bands. I have searched the archives but have not gotten a hit on anything like this.

The problem almost always is not with the K3. I'd say 80% of the time it's the logging or computer program connected to/controlling the K3. Another 5% of the time it's external connections -- grounds, coax connectors, relays, baluns, etc. Another 5% of the time it's operator error. Another 5% is "It's supposed to work that way." And the remaining 5% is other factors, including the K3 itself.

How does the much lower opposite sideband rejection limits the effectiveness of the KX3 in a competitive environment? I have always imagined that everything is good as long as a strong signal doesn't get closer than 1 khz. Am I understanding this right? What would be the IMDDR3 of something like the K3 or K3S at 1 khz spacing? I have never had any issues with the KX3 during contest with IMD, but then I have small antennas; therefore, signals are not very strong.

In-Reply-To: References: Message-ID: <000001d1345c$996e3ff0$cc4abfd0$@biz> Scott, the three rigs use different design formats: The K3 and K2 and conventional superhetrodyne formats with an Intermediate Frequency in the H.F. range and crystal filters to set the passband. The K2 has an adjustable crystal filter and the K3 uses fixed crystal filter bandwidths. The basic K2 bandwidth is established by the crystal filter while the K3 adds an adjustable DSP filter after the crystal filter. (The K2 has an optional audio DSP for enhanced filtering.) Although you will often see Elecraft rig owners refer to "roofing filters" the Elecraft rigs avoid them, using an I.F. in the H.F. range instead that avoids a lot of the compromises involved in up-converting to a first I.F. in the VHF range with a VHF "roofing filter" to set the initial selectivity. The KX3 is quite different. It is a high-performance direct conversion receiver using phasing to suppress the unwanted sideband followed by filtering of the resulting audio. I'm a casual, mostly QRP operator who avoids pile-ups (and so contests) and enjoy all three. If I had to settle on one or the other I'd probably take the KX3 as my first choice because of its small size, the "transparent" sound of a direct conversion format and options such as the PX3 panadapter. My second choice would be my trusty and ever dependable 15 year old K2 simply because I'm basically an "analog" sort of guy. But I have no complaints about the K3/K3S. I'm sure others who enjoy busting "pileups" will have more to offer about the advantages of the K3/K3S.

Re "I am considering the KX3": The one caveat I would add, and others can expand on (or disagree with) this, is that if you operate in a dense ham environment like Field Day or with other nearby hams operating on the same bands the direct-conversion KX3 will not be as good as the two superhets because you may have more difficulty hearing weaker signals with those strong, nearby signals at adjacent frequencies. In Auckland this may or may not be an issue for you -- but as I recall 70% or so of New Zealand's population is in the Auckland area. 73, Phil W7OX On 12/11/15 1:40 PM, Ron D'Eau Claire wrote: > Scott, the three rigs use different design formats: > > The K3 and K2 and conventional superhetrodyne formats with an Intermediate > Frequency in the H.F. range and crystal filters to set the passband.

If he is far enough away, you could work through him. There is one caveat. We do have our antennas really spread out. Our GOTA antenna(s) can be any where from 200'-400' away depending on which of our many antennas are being used at the time. And secondly, all of our radios are using the 8 KHz offset. I was amazed at the demonstration the first time it happened. I would say that the KX3 can handle any intelligently crowed environment. 73, Barry K3NDM ------ Original Message ------ From: "Phil Wheeler" To: elecraft at mailman.qth.net Sent: 12/11/2015 6:23:11 PM Subject: Re: [Elecraft] Receivers? >Scott, > >I agree with all that Ron says -- and have the K2, K3 and KX3 .. and >like them all. > >Re "I am considering the KX3": The one caveat I would add, and others >can expand on (or disagree with) this, is that if you operate in a >dense ham environment like Field Day or with other nearby hams >operating on the same bands the direct-conversion KX3 will not be as >good as the two superhets because you may have more difficulty hearing >weaker signals with those strong, nearby signals at adjacent >frequencies. > >In Auckland this may or may not be an issue for you -- but as I recall >70% or so of New Zealand's population is in the Auckland area. > >73, Phil W7OX > >On 12/11/15 1:40 PM, Ron D'Eau Claire wrote: >>Scott, the three rigs use different design formats: >> >>The K3 and K2 and conventional superhetrodyne formats with an >>Intermediate >>Frequency in the H.F. range and crystal filters to set the passband. >>The K2 >>has an adjustable crystal filter and the K3 uses fixed crystal filter >>bandwidths.

If another station is on the same band, you may not know he is there if he is operating in another portion of the band. However, if he is in the same portion and far enough away, you will know he is there, but you may be able work through him. Hopefully, this reads better. But, remember I said we keep our antennas as far apart as we can and we operate QRP. 73, Barry K3NDM ------ Original Message ------ From: "dave" To: "Barry LaZar" Sent: 12/11/2015 7:10:54 PM Subject: Re: [Elecraft] Receivers? >Barry, > >Re-read your note carefully.

In-Reply-To: Message-ID: I have both a K3 and a KX3 and have used a K2. The principle reason I would consider buying a K2 is for the joy of assembling the kit. When I compare the KX3 and the K3, I think of the KX3 as being about 90% of the K3, but many options are standard on the KX3 but extra cost on the K3. (Note that the K3S is the same as the K3 in these examples.) Examples include: The digital voice recorder -- standard on the KX3. Separate board for the K3. Two memories on the KX3 and 4 on the K3. Dual Watch on the KX3 is a good example of the 90%. The same functionality is available on the K3 with the subreceiver. The difference between the two receive frequencies is limited on the KX3 while the K3 subreceiver is a separate receiver and can receive on different bands. Also, the dual watch needs to have wide enough bandwidth to cover both frequencies which can raise the received noise level. General coverage: Standard on KX3, needs additional filter board on K3. High stability local oscillator: Optional board for K3. Calibration procedure for KX3. (I suspect the K3's solution is more stable.) 100W amplifer: Internal on K3. A separate unit on the KX3. The KX3 is a heck of a good value, and portable too. 73 Bill AE6JV On 12/12/15 at 1:09 PM, zl1chm at gillen.co.nz (Scott Gillen ZL1CHM) wrote: >Can anyone compare the receivers in the KX3 versus K3 versus >K2?

For example, if you have the 2.8 KHz filter installed in RX1, but the 2.7 KHz filter in RX2, you will probably experience this (as I recall). If you can, try selecting a bandwidth while in SSB mode where both receivers will be using the same roofing filters (if they are installed), and see if the frequency shift suddenly disappears. I am not absolutely certain of the above, but I seem to remember that was what I experienced before I upgraded to the the new synthesizers many months ago. 73, Dale WA8SRA > I normally don't have much to post here, but today I do have a question. > > I discovered last night that I have the following situation. > > When in SSB mode on 160 Meters and the 2nd RX is turned on, the SSB > signals > are on the same frequency. > > When I invoke the diversity mode, the 2nd RX is receiving at 1.5 kHz > higher. > > I tested this on numerous signals and at various frequencies; always the > same. > > In the CW mode the problem does not exist.

The difference between the two receive frequencies is limited on the KX3 while the K3 subreceiver is a separate receiver and can receive on different bands.

The K2 is a fairly conventional, single conversion, analogue design. As stated, it uses the crystal filter for primary selectivity. It typically has up to two crystal filter options, one hard wired, and the other as an integral part of the SSB adapter. The hard wired one is adjustable, and the SSB one is fixed. The filters are constructed by the final assembler, from individual crystals. Although there is a DSP option, it works purely on the audio. The K3 and K3X are software defined radios (SDRs) of the non-direct sampling variety. I use SDR in the technical sense, not in the amateur radio community sense; the latter requires the digital processing to be performed on a PC. This means they have an analogue front end with at least one analogue mixer, but the final processing is done digitally. The K3 has a double conversion superhet architecture, with an HF first IF and an extremely low second one. There is a selectable crystal filter (using commercial sub-assemblies) in the first IF, which provides coarse selectivity. The final IF processing is digital. There is a quadrature path starting from the second mixer, analogue at that stage. Combined with digital processing, this creates an analogue of a phasing design receiver to suppress the final IF image, rather than the audio image. As the signal continues in quadrature, the digital processing may also act analogously to a phasing receiver to do the final conversion and audio image stripping, but it may be that the internal logic is more complex than that - the fine details are a trade secret, although they may or may not have release information about that part of it. The K3 also does digital processing on the recovered audio, but this is done within the same digital processor as the final IF processing. The K3X, for CW at least, implements a hybrid analogue/SDR direct conversion, phasing design. For SSB it may do the same, but it is also possible that it actually implements a final passband centre at 0Hz, and then does a final frequency shift to move the centre of the passband to the correct audio frequency (i.e. they could have implemented it as a single conversion architecture). Selectivity is provided entirely by digital processing. For both the K2 and K3, first mixer image rejection is provided by a combination of band pass filters, optimised for each band, and a low pass filter, also optimised for the band. For the KX3, the image is the one removed by the phasing, although there is also analogue band and low pass filtering - I'm not sure whether this is switched, or there is a single, compromise, filter. Block diagrams for all three are fairly easy to find. I have the K2, so did that from memory, but the K3 one is at and the KX3 at . There are likely other places, including a better K3 image. -- David Woolley Owner K2 06123 On 11/12/15 21:40, Ron D'Eau Claire wrote: > The K3 and K2 and conventional superhetrodyne formats with an Intermediate > Frequency in the H.F. range and crystal filters to set the passband.

For example, if you have the 2.8 KHz filter installed in RX1, but the 2.7 KHz filter in RX2, you will probably experience this (as I recall). If you can, try selecting a bandwidth while in SSB mode where both receivers will be using the same roofing filters (if they are installed), and see if the frequency shift suddenly disappears. I am not absolutely certain of the above, but I seem to remember that was what I experienced before I upgraded to the the new synthesizers many months ago. 73, Dale WA8SRA From w4rks73 at gmail.com Sat Dec 12 08:58:30 2015 From: w4rks73 at gmail.com (James Wilson) Date: Sat, 12 Dec 2015 07:58:30 -0600 Subject: [Elecraft] any ideals who might have these?

In-Reply-To: <566BD863.5080505@socal.rr.com> Message-ID: Phil, I am using Field Day as a worst case scenario. I can't think of any situation that is worse than have a collection of radios operating in close proximity, to include their antennas. QRP operation does offer the least challenges, but it still does have its problems. At the other end, the serious QRO stations like W3LPL all take special precautions in field layout and they use bandpass filters. However, I think you know all that. We don't have Frank's acreage to operate. We have to live within 2 acres for everything, but the KX3s do allow us to be less than absolutely rigorous in our operation. We chose what we do because it allows us to operate without the need to use bandpass filtering and the need to model our site so that everything will work. I suspect strongly we could operate at the 100 what level and still make no changes to our site or operation except that we would need to be careful to have only one transmitter on a band at a time, better band management. One could argue the definition of the term intelligently crowed. However, I was thinking that for a co-site operation no two transmitters would be in the same portion of the same band. I may have a bit clumsy with the my definition on this one. Bottom line: my original point is that the KX3 does survive quite nicely in what I would call an RF hostile environment. Will it wilt when things get really crazy? Yes, it will along with every other radio. 73, Barry K3NDM ------ Original Message ------ From: "Phil Wheeler" To: "Elecraft Reflector" Sent: 12/12/2015 3:18:43 AM Subject: Re: [Elecraft] Receivers? >Barry, > >You said "Our Field Day operation uses all KX3s, QRP ...

The IF of the KX3 can be 0Hz (direct conversion), 8KHz (single conversion), or as you point out, in the case of SSB weaver demodulation the 0Hz mark can be placed in the centre of the signal passband, then the I/Q signals are passed through the optional roofing low pass filter before being unfolded/shifted in the DSP. --? 73 de Matt VK2RQ On 12 d?cembre 2015 at 10:55:59 PM, David Woolley (forums at david-woolley.me.uk) wrote: I don't think these descriptions are accurate, particularly the K2 versus K3 one. The K3 has a double conversion superhet architecture, with an HF first IF and an extremely low second one. There is a selectable crystal filter (using commercial sub-assemblies) in the first IF, which provides coarse selectivity. The final IF processing is digital. There is a quadrature path starting from the second mixer, analogue at that stage. Combined with digital processing, this creates an analogue of a phasing design receiver to suppress the final IF image, rather than the audio image. As the signal continues in quadrature, the digital processing may also act analogously to a phasing receiver to do the final conversion and audio image stripping, but it may be that the internal logic is more complex than that - the fine details are a trade secret, although they may or may not have release information about that part of it. The K3X, for CW at least, implements a hybrid analogue/SDR direct conversion, phasing design. For SSB it may do the same, but it is also possible that it actually implements a final passband centre at 0Hz, and then does a final frequency shift to move the centre of the passband to the correct audio frequency (i.e. they could have implemented it as a single conversion architecture). Selectivity is provided entirely by digital processing.

In transmit, the same thing happens in reverse - the mixer sees the 15 kHz output of a DAC. 73, Don W3FPR On 12/12/2015 2:10 PM, Matt Maguire wrote: > In the K3 schematic, I don?t see any quadrature path starting from the second mixer in the RX path ? the two signals lines coming out of that 2nd RX mixer are a balanced (differential) output, not in-phase and quadrature signals.

That sounds like a good reason to do an EEINIT and restore the configuration file. If you need info on how to do EEINIT, look in the manual under Parameter Initialization n the Troubleshooting section.

IIRC, I think the M1 - M4 buttons can be used for macros or frequency selection. See the K3 manual on specifics. You may have accidentally set the M1=MENU as a macro. Try overwriting the M1 button with either another macro or frequency, whatever you want it to do. Good luck.

In returning the settings to use K30 control the only thing I see wrong is that the remote RRC settings indicate the K3S is off. I had not taken a note of this setting when the system was working but the K3S is on and I cannot see why the RRC indicating it is off. I have checked all cables on the K3S and remote RRC.

The MDS and BDR of the K3 (K3S) and KX3 are a bit better, but only marginally so. Take the top 20 transceivers in the Sherwood listing and give them a critical look. There will not be a lot of difference between them in practical operating terms. Measurements are one thing, but actual operating is another. Yes, there are pileup situations where a 1 or 2 dB of difference may make a contact or no contact situation, but those are extreme situations not encountered by the typical operator. The K3 (K3S) and the KX3 are near the top of the Sherwood list, and they will be better in extremely crowded band conditions - listening to a DX pileup for instance where you can 'saddle up' close to another station and not have him bother you (that is what the 2 kHz rating is all about). As for the K3 vs. the KX3, the K3 provides more "buttons at your fingertips" than the KX3 and has a few extra "bells and whistled". My recommendation is that if you are serious into contesting and DXing, the K3 is the better choice. If you want portable operation, the KX3 is the best choice, and the KX3 will provide a great showing in contesting and DXing as well. Bottom line, the K2, K3, K3S and the KX3 are all contest grade transceivers - take your pick based on your preferences and you will not be disappointed. 73, Don W3FPR On 12/12/2015 8:50 PM, Ignacy wrote: > KX3 is a pleasant rig if you don't need second ant, many memories accessed > with few clicks, super tight receiver....

Message-ID: <005701d13600$099d78f0$1cd86ad0$@com> Good Sunday evening, I was playing around with my KX3 on the AM band this morning and moved the receiver down to 435 Khz where I picked up an extremely loud signal. This signal turned out to be a radio station WiQO which broadcasts on 100.9 and is located about 12 miles from my home. The station does not have an AM presence and here are some of the specifications of the FM radio station WIQO; Station Status: Licensed Class A FM Station Effective Radiated Power: 210 watts Height above Avg. Terrain: 511 meters (1677 feet) Height above Ground Level: 20 meters (66 feet) Antenna Pattern: Non-Directional It appears to me that this is an KX3 internal situation. I'm just curious if others have experienced this type of reception in the area of 300Khz to 500Khz. I pick up no other AM or FM stations in this frequency range. I have also made the station manager info on this e-mail.

In-Reply-To: Message-ID: The West Valley Amateur Radio Association (WVARA) Field Day operation, using the K6EI call, has been using a mixture of mostly K3s with some K2s and KX3s. We run QRP and last year entered as 11AB. We have very little difficulty with mutual interference, even when we are running SSB, digital, and CW on the same band. The only extra filters we use are in conjunction with a triplexer which lets use one tribander on 10M, 15m, and 20M at the same time. We have been quite successful with the approach for many years as can be seen from the field day results. This year, we took our operation to Sierra County for the California QSO Party. There we ran 2 K3s and a KX3, all at 100 watts. We kept the SSB stations on separate bands. The worst interference problem we had was when our batteries got low and we got a lot of IMD in our signals. That caused interference between our stations. Replacing the batteries with freshly charged batteries cured the problem. 73 Bill AE6JV On 12/12/15 at 9:58 AM, k3ndm at comcast.net (Barry LaZar) wrote: >I am using Field Day as a worst case scenario.

It must be located OUTSIDE your shack to choke the common mode currents from entering the shack. Wind about 15 - 20 turns of your coax on a 6? PVC pipe. This will give you about 2500 ohms choking impedance. If there is still RFI getting in the shack, then purchase a commercial choke either from http://www.balundesigns.com/model-1115d-max-choking-1-1-balun-1-54-mhz-5kw/ this will provide about 10 - 12 000 ohms of choking impedance, or buy one from http://myantennas.com/wp/product/cmc-130-3k/ This one will give from 12 000 - 15 000 ohms of choking impedance. These common mode chokes merely get plugged inline in your coax cable. Always better to locate them outside the shack 73 John On 23 Nov 2015, at 1:02 AM, Jan Ditzian wrote: I have a problem that appears to be changing, but I could use some help. The problem is RFI in the audio input (microphone input) when I use my vertical antenna on 40 meters. Here is a rundown of what has happened: I have a 67-foot elevated vertical that I can use on 80 and 40, and it works fine on CW. However, on SSB, both bands, there clearly is feedback; there is no feedback on the other bands where I use a C3 yagi. Initially, the feedback was so bad that the rig would go into oscillation, and I had to turn the amp to standby. I recently purchased the new KSYN3A and decided to install it. I replaced the K3 with my IC-730 backup, using the hand microphone that came with the 730. The 730 did not have any RFI. I finished the modification and returned the K3 as the operating rig. Now, the RFI on 40 seems to have diminished substantially or disappeared, but it still happens on 75/80. However, it seems to be much less there as well. I do not suspect that the KSYN3A had anything to do with this, but perhaps I tightened connections better when I returned the rig to service. I also redid some ground connections. The microphone for the K3 is an Audio-Technica that works well everywhere else. It has a long cord, though. I put a few toroids on the cord near the microphone connector and that has possibly reduced RFI a little, but it is still there. Is there a possibility that a bypass capacitor is bad, or has someone else had the problem and solved it externally to the K3? For instance, has anyone found that a long string of ferrite beads has cured this problem? Despite decades of operating, I am hardly a troubleshooting hotshot, and I would appreciate guidance.

First, RS-232 is a point to point system. The use of "Y" connectors is not the norm and are applicable only under certain specific conditions. Those conditions are that the device added by the "Y" connection has no active drivers on the RS-232 signals - only line receivers are permitted. Think of it this way - a driver on an RS-232 line can have a negative voltage of up to -25 volts, and a positive voltage of up to +25 volts. Imagine that one driver is trying to produce -25 volts while the other driver is trying to produce +25 volts. In other words, they 'fight' with one another, and the result is 'confusion' because the receiver listening on that RS-232 signal line will not respond to a voltage that is less than 3 volts positive. In other words, use a "Y" connector only when the added device is capable of being put into a "listen only" mode (with its drivers disabled). Look at your amplifier information carefully to see if it can be placed in a "listen only" mode. If not, you cannot use it with a "Y" connector. The SteppIR is one example of a device that can be placed in listen only mode, so the use of a "Y" connector is possible, but that is not the general case. Bottom line, you can connect only *one* RS-232 device to another in the general case. Introducing a 3rd RS-232 device (with a "Y" connector) requires special conditions be present in that 3rd device - it must only listen to the data traffic and not attempt to transmit data. 73, Don W3FPR On 12/13/2015 10:52 AM, charles at k5ua.com wrote: > > > I have an OM2500A amp that works perfectly with my K3S when it is the > only thing connected to the RS232 of my K3S. > > I am using LP-Bridge and Na3P to create a panadapter and this works > perfectly when the computer is the only thing connected to the RS232 of > my K3S. > > The manual shows how to use a RS232 "Y" splitter so that two devices can > share the RS232 port of the K3S, but when I use the "Y" splitter (one > side to the OM2500A amp and one side to the computer) the following > malfunctions occur: > > 1.

My KX3 and PX3 kits and assorted goodies arrived 2 days ago. I have to build 2 computers before I got to open the boxes, but last night I build the KX3. It was a pleasure to build, the instructions were excellent, and save for having a minor bit of trouble making SURE the 4 pin connector of the ATU was seated, I had no issues. Bending the toroid under the antenna connector was a challenge, but I did it with a small hemostat, and it worked well. One of the windings seemed a little loose after I did so, but I don't think there will be an issue. Smoke test was fine, fired it up and enabled the autotuner. Not much on the bands, but I was able to confirm reception of some CW that my IC-746 Pro could barely hear. All in all, a fun nite. Tonight, I build the PX3! Just thought I'd share.

It seems like that is what is happening, the OM2500 may be sending info back on the line into the "Y" connector, confusing Na3P on the computer end on making the OM2500 jump frequency rapidly back and forth between the correct frequency and the out-of-band phantom frequency. From the responses, there may be 3 possible solutions: (1) I read N8LP's comment under a different thread heading than this one. I am using his LP-Bridge program and LP-Pan hardware. Larry said that I could use one of the extra serial ports in LP-Bridge to send data to the OM2500A. I think that will work if I put a Serial to USB converter coming out of the RS232 port on the OM2500A going back to a USB port on the computer. (2) If all else fails, I have used DDUTILl in the past to talk to the OM2500A using the CI-V format into the CI-V port of the OM2500A. I don't really want to use two virtual serial port programs (DDUTIL and LP-Bridge), but I might have to try that. (3) I will email OM Power to ask if I can put the OM2500A into "passive listener" mode only. I thought that I might be able to accomplish the same thing by removing the wire in the DB-9 cable that would carry signals from the OM2500A back to the "Y connector, thereby making it a "passive listener" by default. If you look at the K3S DB-9 wire definitions in the manual, one of the wires is RX and one is TX. I was thinking that if I removed the Line 3 TXD OUT pin from the cable going to the OM2500A, any signals coming from the OM2500A would never get back to the "Y" connector to confuse the computer that is listening on the same line. On page 18 of the manual there is a table of the DB-9 pin-out. Although the names of the pins seem counter-intuitive to me..... Pin 2 (RXD IN) is used to _SEND_ data from the K3 _TO_ the PC and the OM2500A. Pin 3 (TXD OUT) is used to _RECEIVE_ data _FROM_ the PC or the OM2500A. I'm thinking that removal of Pin 3 from the side of the "Y" splitter that goes to the OM2500A will allow the OM2500A to _RECEIVE_ signals from the K3S/PC _BUT NOT SEND_ signals to the K3S/PC. Does that make sense? Would like to receive comments on these three possibilities. Thanks for all who responded.

I think you are right, I failed to consider signals going from the PC back to the K3S, they would go directly to the OM2500A as well. I guess using a different virtual serial port under LP-Bridge as suggested by Larry N8LP is the most promising solution since I am using LP-Bridge anyway for Na3P. Thanks for your post.

To make sense of the signal directions, you have to know whether the device is configured as DCE or a DTE. Data Communications Equipment or Data Terminal Equipment. The 'transmit' and 'receive' signals are relative to the DTE. In other words, the signal on pin 2 (RXD) will have a receicver in the DTE and a Driver in the DCE. The PC is the DTE and devices like the K3 and your amplifier are DCE type.

In order to resolve things, I built an 80-meter dipole to use as a test antenna. While all this was happening, over the past few months, I also added a used KAT-3 tuner and a KXYN3A to replace the original synthesizer. After building the dipole, I was puzzled that it would not tune up on 80. I do not know why it took me a week, but I finally checked out the rig on my dummy load. It shows a high SWR on the dummy for all wavelengths greater than the 40-meter band--60, 80, and 160. The rig works just fine on 14 mHz. and up, and I can certainly tune it up on 40 meters. Further checking shows that there is no output on 60-160, whether using the Tune mode at 5 watts or CW mode at 70 watts. I have no idea when or why this happened, but I really need to know the how it happened, so I can fix it. Can someone give me some guidance on what to look at to figure this out? It is possible that resolving this problem will also result in a resolution of the RF feedback problem, although I won't count on that. 73, Jan, KX2A From fcady at montana.edu Mon Dec 14 16:33:23 2015 From: fcady at montana.edu (Cady, Fred) Date: Mon, 14 Dec 2015 21:33:23 +0000 Subject: [Elecraft] K3s USB audio In-Reply-To: References: , Message-ID: No problem here with N1MM+ playing wav files through the USB audio codec.

Some folks think it is just plain wrong to label a signal TXD (transmit data) when it really is a receiving signal line. Or RXD when it is actually transmitting data. That is what pin 3 and pin 2 on the RS232 connector on your K3 are. About the only sure way to figure out what is an active source is to look at a schematic or measure the pins with a volmeter/scope or get one of the RS232 blinky boxes. For some more information, have a look at http://www.ke7x.com/home/miscellaneous-k3-information/unexpected-agc-behavior/rs232-interfaces-1 For even more fun and games, read up on the history and use of the handshaking signals RTS, DTR, CTS and RTS.

It all depends on whether you are a DTE or a DCE device. Prior to the IBM PC, all was well defined and an RS-232 interface used a DB-25 connector. AFAIK the IBM PC was the first to use the DE-9 connector for the serial port connector, and they initially envisioned the PC being used as a terminal device connected to a large mainframe - so the mix-up began there - thus the PC is a DTE device, and when things are run from a PC, the signals are "backwards". This state of affairs was adopted In any case, pin 2 is the DE-9 signal line for data *TO* the PC. So the proper check is for a driver on pin 2 in your amplifier. If your amplifier also implements other RS-232 signals that use drivers in the amp, it is likely that those should be disabled as well - check for drivers on pins 1, 6, 8 and 9 of the DE-9 connector. And just another twist on the connector designation - the 9 pin connector commonly used is properly a DE-9. References to it as DB-9 anre quite common, but are incorrect. If you look at the general category of D-sub connectors, the first letter is properly "D", but the 2nd letter refers to the shell size - "B" is the long connector typically seen in computer parallel ports, "E" is the smaller shell commonly used in PC serial ports. It is usually not important until you get to the typical 15 pin video port on computers - that is properly a DE-15HD connector. DB-15 connectors also exist, but it is longer and has 2 rows of pins rather than the 3 rows of the DE-15HD. Standards are standards, but many manufacturers do not conform to those standards. Never make the mistake of thinking "it looks like a computer serial connector, therefore it should be one" - that thought can lead to damaged equipment. Check the equipment manufacturer's manual. If it is not marked RS-232, it is not likely to be RS-232. 73, Don W3FPR On 12/14/2015 2:50 PM, charles at k5ua.com wrote: > > > Thanks for the detailed explanation Don.

It didn't work, and Don provided a clear and detailed explanation why that was the case. Serial data is echoed bidirectionally through the OM2500A. There is no "listen only" mode that I'm aware of.

The key thing to remember with RS-232 is that while you can usually have multiple devices listening to a path, only one can transmit. 73, Eric /elecraft.com/ On 12/14/2015 5:13 PM, Josh Fiden wrote: > Charles, > > At this point, it seems like a silly question.

It is the modem that is the DCE. The specification is really one for connecting things to modems. Initially PCs used 25 pin connectors and they were fairly rare in using them with the correct gender, male (as defined by the pins) for DTE and female for DCE. Even after the move to 9 pins, they continued to use this convention. Therefore, if you have a device that has a male connector, you can be pretty sure it is configured as a DTE. A female connector, unfortunately, is not a guarantee of the converse, and the K2, at least, appears to be non-compliant. It looks like the K3 has the same non-compliance. -- David Woolley Owner K2 06123 On 14/12/15 23:08, Don Wilhelm wrote: > AFAIK the IBM PC was the first to use the DE-9 connector for the serial > port connector, and they initially envisioned the PC being used as a > terminal device connected to a large mainframe - so the mix-up began > there - thus the PC is a DTE device, and when things are run from a PC, > the signals are "backwards".

Message-ID: Hi, It's come to my attention that my signature line has been getting thru into my list posts. After fact-checking my sources for my last rotating signature line (they change often and I tend to fact check pretty consistently), my most recent line was factually completely incorrect, and the attribution was false. I generally use NO signature line in mailing lists and forums such as these. I have a small program that deletes any signature material when I post to forums or mailing lists, which seems to have glitched, but is now in place again. Consider this an apology for both the factual error and for the malfunction itself. This is a great group, sorry to make waves and for the controversial and INCORRECT supreme court quote geting thru into my posts! 73 Mark KD8EDC From n5ia at zia-connection.com Tue Dec 15 11:28:02 2015 From: n5ia at zia-connection.com (Milt -- N5IA) Date: Tue, 15 Dec 2015 09:28:02 -0700 Subject: [Elecraft] K3 sub RX off freq in SSB diversity mode In-Reply-To: References: Message-ID: <18AA84519529427CB4C7283108D78CAE@Milts2009> Well, after following some suggested routines by various on and off list repliers, the problem still exists.

When I invoke the diversity mode, the 2nd RX is receiving at 1.5 kHz higher. I tested this on numerous signals and at various frequencies; always the same. In the CW mode the problem does not exist.

Rest assured there will be a great, very hard to miss, buzz on the reflector when the rest of the retrofits are available. The word is that they have to get production for these boards far enough ahead of numbers needed for K3S construction. There seems to be a firm demand for K3S. I know three among my local hams who had a K3, who had always talked about getting a second K3, and got a new K3S as their second K3 when they came out. None of them sold their K3. :>) The real biggie in the retrofitting, the KSYN3A, has been out there for K3 for a good while now. 73, Guy.

This will involve a few interim releases with different testing requirements, and I'm hoping to find testers who can directly benefit from each set of changes. This first interim release corrects a reported problem with PTT use from the N1MM software application, and possibly others. In rare cases, when PTT is used to start transmit, the "RX;" command from the software application doesn't return the radio to receive. This is primarily a CW-mode problem but it has been reported in other modes. I believe I have this fixed for all modes. If you've seen the symptom and don't mind putting this new code to the test over the next couple of days, please email me directly (not via the list).

If I read your post correctly, the K3S already has the ability to communicate with the computer thru the USB port, AND echo the same data through the RS232 port to the amplifier. In fact, after digging through the CONFIG Menu I found that setting AUTOINF to AUTO 1 will send band data on its RS232 port!! That should solve my problem! Will try it. Thanks for your post Eric.

I would suggest that you not break off the pins unless you have a cable with formed and sealed backshells. If you can open the backshell, just cut the wires on the 'backside' of the connector. 73, Don W3FPR On 12/15/2015 7:03 PM, charles at k5ua.com wrote: > > > One more question Eric. > > If I need to block the TX lines from the amplifier to the K3, which pins > should I break off of the male DB-9 connector? > > Thanks again for your help. > > Charles K5UA > > > ______________________________________________________________ > 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 w3fpr at embarqmail.com > From bill at wjschmidt.com Tue Dec 15 19:21:27 2015 From: bill at wjschmidt.com (Dr. William J.

I have no idea when that 'sometime' is because I have no information about the production capability of the board house supplying Elecraft with the KIO3B vs. the number of K3S units being ordered and shipped. When there are enough in house to supply both the K3S and the expected deluge of orders anticipated for K3 upgrades, then you will see the KIO3B offered for K3 upgrades.

This is intended for use with transverters, but it can also allow the K3 to act as a very stable, very low-noise signal generator.To route RX and TX through the XVTR jacks on all bands, set CONFIG:KXV3 to TEST. When milliwatt-level output is in effect, rotating PWR will show milliwatts on VFO A, and dBm (dB relative to 1 milliwatt) on VFO B. The RF bar graph displays power output in tenths of a mW.*/Does anyone know if it outputs a signal on any and all frequencies the K3 is capable of using this process, such as the AM broadcast band between 500 kHz and 1.6 mHz and the international shortwave broadcast bands?*/I've been reproducing some vintage 1920's and earlier crystal sets and regenerative receivers, and would like to use the K3 as a calibrated signal source when testing the bandwidth of parallel tuned circuits and tank circuits in these vintage rigs.

Seems the K3 was funded partially by guys paying up front and having a 6 month wait when this started years back, I assume a lot of those are still around and willing to pay up front if money is that short now. Stretching some of this stuff out for a year or more does not help business, only the most dedicated go for that idea. Perhaps its a labor shortage/paying for more labor, cant sell them yet as no instructions written, or "testing" done? Seems there are a number of guys willing to help out on that end. So all the quiet and non fulfilled talk is just that, talk, just being honest and frank about whats up and why its not available would put to rest the speculation and angst that silence brews. Not criticizing, just wondering, I need a couple and keep putting off installing KYSN3 boards in one radio, its been apart for so many mods the screws are wearing out, had to replace them to keep it decent looking.

Which reminds me on another thing, I have had lots of knobs crack on the K3 Elecraft has been super at replacing them, the last ones I got have a metal insert and will never crack I assume, but they are butt ugly, instead of semi shiny black knobs, they are a dull black material that looks like something that came on some military piece of junk.

As yet I am not a licensed ham, but a prospective candidate to join the ham radio hobby. I have no vested interest in the Elecraft business, neither do I have ties to any of the management personnel. In doing my research as to what equipment to purchase, there were a number of aspects I took into consideration, price was not the most important. "Customer Service" was paramount, made in the USA was very important, supporting documentation and acceptance from the ham fraternity was a condition of my final decision. Whilst this is not an exhaustive list of criteria to purchase from Elecraft or any other supplier, no other supplier came close to meeting all of these criteria. Your personal list of criticisms in this post is totally unfortunate and uncalled for. If you are genuinely invested in your hobby in these days of extremely difficult business conditions and took the trouble to visit with the Elecraft folk at their manufacturing plant you will be amazed to see just how professional a business entity they are and just how far they do go to satisfy all the needs of their customers (and prospective customers) What is needed in these challenging economic times is overwhelming support from their customers, even if Elecraft are unable to deliver every permutation of what we the users "think" they should be delivering to us. In my opinion, having visited the manufacturing facility, they are doing more for their customers now and in the future, to stay invested for the future in facilities, personnel and product development so that we as hobbyists can remain invested in our hobby. It is about time we stopped trying to second guess and critically challenge management publicly, before we have taken the time to comprehend their role in producing a product of great quality. We, the customers, should strive to encourage and support. That is far more difficult than degradation. Working with Elecraft in 2016 and beyond is our job to ensure we have a supplier committed to the hobby for many years to come.

I recently (10 minutes ago!) discovered that I prefer the sound of this wide passband with MENU:AGC ATK set to 207 instead of 215 (the default value). It may be the particular quality of the noise on 40 meters tonight. Not sure. But this slightly slower attack time creates a warmer sound with fewer fast transients on noise peaks. To change the attack time: - hold MENU - using VFO B, select the AGC THR menu entry - tap the '2' switch [ATTN] to change the name of the menu entry to AGC ATK (this is one of several AGC parameters -- see menu listings) - set the attack parameter to 207 (or experiment a bit) using VFO A - tap DISP to exit the menu Again, you may not notice any difference unless you're on a pretty noisy band using a wide filter setting. The change has little effect in SSB or other modes, which have a different attack characteristic generally. With the attack set to this lower value, it's possible that extremely strong signals might create a slight overshoot when they hit the receiver. Or not. I'd be interested in others' opinion of this change. If the response is extremely positive, we might consider reducing the default value. 73, Wayne N6KR From arcticpeak at yahoo.no Wed Dec 16 07:42:16 2015 From: arcticpeak at yahoo.no (Martin Storli - LA8OKA) Date: Wed, 16 Dec 2015 12:42:16 +0000 (UTC) Subject: [Elecraft] K2 Hand microphone In-Reply-To: References: Message-ID: <1311824252.3317689.1450269736718.JavaMail.yahoo@mail.yahoo.com> The Kenwood MC-43 gives much better audio quality than the MH2 on my K2.?Martin Storli LA8OKAOslo, Norway ?ARCTICPEAK's Radio pages! http://www.arcticpeak.com/radio.htm Fra: Aaron Scott Til: elecraft at mailman.qth.net Sendt: Tirsdag, 15. desember 2015 20.30 Emne: [Elecraft] K2 Hand microphone I need to get a hand microphone for my K2 and I have hear great things about the Elecraft K2 MH2 and Kenwood MC43S.

The boards are being populated by a board assembly house in California. In order to increase their production of the finished boards, they would likely have to hire more people and purchase more equipment. That is not a smart business move if the volume will taper off after the "crunch". So we have to wait until things 'even out' before those boards can be available for K3 retrofit. If a cookie manufacturer has capability of producing 100k cookies a day, but the holiday season customers want 125k cookies per day, do you think the manufacturer would increase the production facilities - especially if the demand would fall off to only 100k per day after the holidays? It is the same principle. I am quite happy with the RS-232 interface for my K3 and already have the external soundcard working, so I will not be begging to get the schedule advanced. 73, Don W3FPR > -------- Original message -------- > From: Merv Schweigert > Date: 12/15/2015 6:15 PM (GMT-08:00) > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] KIO3B > <> > We will have boards when the K3S demand is met? sounds like there is not > enough money to buy more boards than what they expect K3S sales to be? > Ordering another few hundred extra of the boards would solve the problem > of not > having enough on hand.

The issue for me is that my radio is at my place on J6 where my electronics lab is not. I have three options: 1. Bring the radio back and fix it, 2. Try to fix it down there (with very minimal resources), or 3. Bring a new part down with me to swap out and trouble shoot the broken part back here in the states. Ordering a new KIO3 would be less than smart. I decided last night i would simply order a new K3s, tell Elecraft to hot shot the KIO3B out of it and keep the radio/ send the radio with a replacement KIO3B when they become available (months from now, i don't care).

We build the assembled K3S base units ahead of time before option configuration, and for kits, the KIO3B boards are inside of sealed boxes of kitted product packaged ahead of time. We are also fully maxed out getting December orders out the door for last minute shoppers, presents etc. Fortunately, we will begin taking orders for the KIO3B board set the week after next - after the holiday rush. This will probably on either the 29th or 30th, and we expect to begin shipments 5-10 days after that. We should have the extra KIO3B boards in-house and tested by then. Please do not try to order or call before we announce that the order form is up as we do not have the web order form or internal order systems ready to handle KIO3B upgrade orders. (We prefer on-line orders to avoid phone overload here..) We are also maxed handling the holiday order rush. We will post here on the Elecraft List and of course on our web page as soon as we are ready to take orders and the order form is up and running. We're running as fast as we can - Its a busy month at Elecraft this time of year. 73, Eric /elecraft.com/ On 12/16/2015 8:03 AM, Dr. William J.

For me, the K3IOB is not an upgrade, per se, but a necessary part to get my broken K3 on an island in the Caribbean fixed. Alas, my K3 shall remain broken for a few more months while I await a stock of replacement parts (a few months because I only get there every few months at best). I guess I?ll bring my Icom 756 Pro II along with me on the plane tomorrow. So much for my (highly touted, and maybe not so permanent) K3. Dr. William J.

Schmidt, II Subject: Re: [Elecraft] KIO3B Hi Bill (and everyone else interested in the KIO3B upgrade), Unfortunately pulling the KIO3B boards out of a packaged K3S kit or already built K3S is not practical, and would really cause production problems here. We build the assembled K3S base units ahead of time before option configuration, and for kits, the KIO3B boards are inside of sealed boxes of kitted product packaged ahead of time. We are also fully maxed out getting December orders out the door for last minute shoppers, presents etc. Fortunately, we will begin taking orders for the KIO3B board set the week after next - after the holiday rush. This will probably on either the 29th or 30th, and we expect to begin shipments 5-10 days after that. We should have the extra KIO3B boards in-house and tested by then. Please do not try to order or call before we announce that the order form is up as we do not have the web order form or internal order systems ready to handle KIO3B upgrade orders. (We prefer on-line orders to avoid phone overload here..) We are also maxed handling the holiday order rush. We will post here on the Elecraft List and of course on our web page as soon as we are ready to take orders and the order form is up and running. We're running as fast as we can - Its a busy month at Elecraft this time of year. 73, Eric elecraft.com On 12/16/2015 8:03 AM, Dr. William J.

Ordering a new KIO3 would be less than smart. I decided last night i would simply order a new K3s, tell Elecraft to hot shot the KIO3B out of it and keep the radio/ send the radio with a replacement KIO3B when they become available (months from now, i don't care).

Mathematica already supports a pretty descent range of devices to feed data real-time. Not sure if it could handle the bulk of real time of actual signal frequencies. Also, Mathematica runs on Raspberry Pi and supports a number of data interfaces as a result of that work (part of their device support). However, my interest is not real-time. I am more interested in studying the math part of digital signal processing. That is what Mathematica is good at doing. I have ZERO (capitalized for great emphasis) interest in making my own SDR, after all, I have a KX3 (and most other rigs made by Elecraft). I have used Mathematica for many different projects over the last 15 years and some of those were gigantic number crunching projects for work. But, now that I am retired, I have the Home Edition of Mathematica (actually two copies, one for the iMac and one for the Macbook Pro) and I use it for physics calculations, antenna analysis (I built a runtime interface to NEC4), and even game playing such as solving Sudoku puzzles and playing chess. It is a great functional and pattern matching language besides the big ?curated? data interface it now supports (from the work of WolframAlpha). 73, phil, K7PEH > On Dec 17, 2015, at 8:33 AM, Per-Tore Aasestrand wrote: > > Interesting! > > Will Mathematica be able to handle the data-stream in real-time? > > 73 > > P-T / LA7NO > > > On 17 December 2015 at 17:29, Phil Hystad > wrote: > I thought of doing something with Python and SDR I/Q processing but never got around > to doing anything.

We build the assembled K3S base units ahead of time before option configuration, and for kits, the KIO3B boards are inside of sealed boxes of kitted product packaged ahead of time. We are also fully maxed out getting December orders out the door for last minute shoppers, presents etc. Fortunately, we will begin taking orders for the KIO3B board set the week after next - after the holiday rush. This will probably on either the 29th or 30th, and we expect to begin shipments 5-10 days after that. We should have the extra KIO3B boards in-house and tested by then. Please do not try to order or call before we announce that the order form is up as we do not have the web order form or internal order systems ready to handle KIO3B upgrade orders. (We prefer on-line orders to avoid phone overload here..) We are also maxed handling the holiday order rush. We will post here on the Elecraft List and of course on our web page as soon as we are ready to take orders and the order form is up and running.

That gives you a output that is prior to any IF filters in the K3S.

I have owned my K3 for about 2 months, after researching matters fully and finally making my decision to buy. As a benchmark, I also collect and operate Collins radios, which are works of art and evoke the character, talent, vision and elegance of Art Collins. I love my K3 and greatly admire Elecraft for reasons that parallel why I love Collins radios and the legacy of Art Collins. In at least these respects: 1. Elecraft are people who clearly build these radios as a labor of love. They operate cw (sometimes during lunch break!), do QRP, hike and accordingly know what?s needed to build radios that are a joy to operate ? even outdoors and on the trail where radios are put to the greatest test. They come from a long line of great radios, having built the NorCal 40 and the Sierra, among other great radios. I can tell from the craftsmanship, design, attention to detail and ergonomics, that my K3 is a labor of love. 2. I admire their story. I admire how Wayne Burdick left his day job to start this company, and how Eric also bet his assets on the venture as well. They believe in and love what they do, and my K3 sitting in my shack always reminds me of that powerful story. They are not beholden to the bankers who might encourage more massive production, corner cutting and expediency, next-Q profit mentality over quality. They have the discipline to avoid spreading themselves too thin. They have the courage to keep their focus on doing things well, even if that sometimes means we have to wait. Sometimes, as here, good things come to people who wait. 3. Their manual is well written, well organized, cogent, and pleasing-to-read ? some of the best technical prose I have ever read (this I can say after practicing telecoms patent law for 33 years). The manual is not just some random listing of buttons and features like you see in other manufacturers? manuals, but rather reflects the thought, care and organization of someone who has put himself or herself in the operator?s shoes. 4. As a builder, I appreciate the thought, competence and innovation reflected in how their circuits are designed, for maximum performance and reliability, and minimal power consumption. I also think it?s great they don?t seem to feel compelled to hire a Jony Ive for the latest cosmetic design in order to sell radios. 5. Their customer support is orders of magnitude above everyone else. The other night, for example, I sent an email about some error messages I was getting, and Elecraft responded with the correct fix early the next morning. Turns out I had inadvertently, in boneheaded fashion, hit the Config button and changed a setting. The level of care, tact and patience reflected in the email, on top of the raw technical competence, were not lost on me. 6. That said, I am doubly dismayed, saddened and annoyed when my reflector message list is fouled with the whining of people who seem blind to these great radios and this great company. People who whine because they want whatever *right now *so they can dash off to their island without delay, who are cheesed because the knobs are not sufficiently shiny, who seem affronted by the notion of having to open their radio up to add some of the amazing boards and circuits offered by this best-of-planet company because it might mar the paint job. I am reminded of that New Yorker cartoon some years ago that shows a Met Patron standing in front of a Monet and complaining, reflecting more on herself than on the artist. Would you people please *just stop*? Thank you.

For those who offered advice on the evening of the failure, and others who later submitted hypotheses about the cause of the problem, my thanks again; and here's the diagnosis from Don: ". . . one of [the PA transistors] had a collector-to-base short . . . A bit of wire (suspected to be a component lead cutoff) was found on the bottom of the board. It is only speculation, but that wire could [also] have caused the initial short." A lesson there. Clean up before closing up. I ought also to mention that Don had the rig repaired, calibrated and aligned, and on its way back to me within less than a week of the day I sent it to him. Outstanding. So, stand back everyone: Next week K2 S/N 7637 will be on the air!

If other than that, please correct me. The SWR displayed on the Transmit monitor is the SWR on the transmission line to the antenna - in other words, it is the SWR at the *output* of the tuner in the K3S. The wattmeter in the K3S indicates the SWR at the *input* of the KAT3. It tunes to 'keep the K3S finals happy'. That will not change the SWR on the feedline to the antenna. If you were to place the TX monitor sensor between the K3S PA and the KAT3 (impossible to connect there), then the TX monitor and the K3S should agree. In other words, the term "Antenna Tuner" is not an entirely correct term. It does not change the SWR on your antenna and feedline, but instead transforms the SWR at the output into a low SWR at its input. An ATU is a system of lumped components that compensates for the SWR on the antenna and feedline and transforms it to a low SWR at its input to match the 50 ohms resistive match wanted for maximum efficiency from the transceiver PA transistors. In other words, the K3S is showing you the SWR at the *input* of the KAT3, but the SWR at the *output* of the KAT3 will not be changed. If you want to change that, you will have to work on your antenna and feedline system. 73, Don W3FPR On 12/18/2015 7:35 PM, Ferris Jennings wrote: > Hell-o Everyone - > > > > Finished building my K3S and P3 (with TX Mon), and I'm starting to play with > the configuration/menus. > > I have the KAT3 ATU installed, and it works great.

You can either plug it directly into the 3.5mm jacks on the rear panel and program a function key (typically PF1) to turn the speaker(s) On/Off or you can use an 1/8" to 1/4" adapter for the headphones and a Heil AD1-K (Kenwood) adapter to connect the mic to the front panel (Foster) mic jack.

(no coax jumper to the sensor). The reason for the question is this. The tuner in the K3S adjusts the impedance the K3S's finals see to 50 ohms at the input to the KAT3 inside the K3S, but the impedance the KAT3 sees at the ANT connector to the coax might be quite different. That's what the KAT3 does. It transforms whatever impedance it sees at the ANT connector to 50 ohms, non reactive or as close as it can get and that's the SWR you see reported. It tells you the K3S finals are delivering power most efficiently to your antenna system. But it does nothing about the SWR on your coax feedline to the antenna. Unless your feed line is exactly 50 ohms and it is seeing exactly 50 ohms at the antenna, there will be standing waves on the feed line. The idea is to keep them low enough to prevent excessive feed line losses, but the SWR is virtually never zero. The impedance at any point along your feed line will vary as you move from the rig to the antenna. That's dependent upon the SWR on the feed line and the frequency. Any feed line between the sensor in the KAT3 and the sensor for the P3 TX MON will cause them to see different impedances and so they will report different SWRs. The best way to check the two is to mount your P3 TX MON sensor right at the K3S ANT connector with a double male adapter so there's an absolute minimum of feed line between the KAT3's SWR bridge in the one in the IX MON sensor. Ideally terminate the TX MON sensor in a good 50 ohm dummy load instead of connecting it to the antenna. Then both SWRs should agree within a reasonable range. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ferris Jennings Sent: Friday, December 18, 2015 4:36 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KS3/P3 SWR Display Readings Hell-o Everyone - Finished building my K3S and P3 (with TX Mon), and I'm starting to play with the configuration/menus.

In other words the SWR reading in the K3S (via KAT3) is the result of "matching" antenna to the output of the amplifier in the radio (LPA or KPA3). Your sensor for the TXMON is between the antenna and the radio so does not know of the "match" and reports the un-matched SWR of the antenna. Oh, the first law, "You can never have too many SWR meters, in the closet."

In effect, the VOX and PTT functions are in a logical OR relationship - if either one of them wants the rig to be in transmit, it will be in transmit. In your current setup you could disable computer PTT control entirely and you would not see any difference. There is a way to set the VOX delay to nearly zero, and that is to enable QSK. With PTT and QSK enabled, your computer messages will be controlled by PTT (no RX between characters), but your paddle-sent CW will be QSK. If you are using a non-QSK amplifier, this won't work for you. Without using QSK, you can reduce the VOX delay in the K3, but if you are using an external amplifier that is not capable of QSK, the amplifier may impose a lower limit on the VOX delay you can safely use, i.e. you may want to have a VOX delay long enough to prevent returning to RX between characters, and maybe also between words, during paddle input, and that VOX delay will also affect the end of computer messages. If you have an external keyer that has a PTT output, you can wire-OR the keyer's PTT output with the PTT signal from the computer. When the computer is sending, PTT will be asserted by the computer and there will be no RX during messages, but no delay in the return to RX at the end of the messages. When you are sending from the paddle, the delay will be controlled by the keyer's PTT settings. If you have a non-QSK amplifier you will have to configure the delay in the keyer to accommodate the amplifier, but the delay will only apply to paddle-sent CW, not to computer-sent messages. 73, Rich VE3KI S57AW wrote: > Simple question...

Adding the usb sound and USB data hw to that did not increase the end price by over $200. Lastly at ham radio market volumes, which are much lower than most consumer products, the cost to develop and support any design is folded in the price we must charge over time.

Ah, it all makes sense ... now. I kept thinking that the SWR signal was being sent from the K3S to the P3 via the RS232 port. Wrong. So, guess I have, with the P3 SWR display, something of an antenna analyzer. Nice to be able to have the K3S provide an "adjusted" SWR and the P3 provide the real SWR at the antenna. Seems like my antenna does need a little work. That project will have to wait a while.

(no coax jumper to the sensor). The reason for the question is this. The tuner in the K3S adjusts the impedance the K3S's finals see to 50 ohms at the input to the KAT3 inside the K3S, but the impedance the KAT3 sees at the ANT connector to the coax might be quite different. That's what the KAT3 does. It transforms whatever impedance it sees at the ANT connector to 50 ohms, non reactive or as close as it can get and that's the SWR you see reported. It tells you the K3S finals are delivering power most efficiently to your antenna system. But it does nothing about the SWR on your coax feedline to the antenna. Unless your feed line is exactly 50 ohms and it is seeing exactly 50 ohms at the antenna, there will be standing waves on the feed line. The idea is to keep them low enough to prevent excessive feed line losses, but the SWR is virtually never zero. The impedance at any point along your feed line will vary as you move from the rig to the antenna. That's dependent upon the SWR on the feed line and the frequency. Any feed line between the sensor in the KAT3 and the sensor for the P3 TX MON will cause them to see different impedances and so they will report different SWRs. The best way to check the two is to mount your P3 TX MON sensor right at the K3S ANT connector with a double male adapter so there's an absolute minimum of feed line between the KAT3's SWR bridge in the one in the IX MON sensor. Ideally terminate the TX MON sensor in a good 50 ohm dummy load instead of connecting it to the antenna. Then both SWRs should agree within a reasonable range. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ferris Jennings Sent: Friday, December 18, 2015 4:36 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KS3/P3 SWR Display Readings Hell-o Everyone - Finished building my K3S and P3 (with TX Mon), and I'm starting to play with the configuration/menus. I have the KAT3 ATU installed, and it works great. But I do have a question regarding the SWR displays. I'm running a simple diploe, and the KAT3 tunes it down to 1.0-1 in a second flat. However, the SWR meter on the PS display always reads way higher, something like 2.9 - 1. I've swapped antennas and lead (another dipole), and I get the same results. Question is: why the discrepancy in SWR from the K3S display to the P3 display? Am I missing a configuration setting?

Nevertheless it's a question of perspective. I already own all the other features of/with the KIO3 so I can only make up my mind on the additional features and decide if it's worth it or not as that is what makes the difference for me. If they would offer a trade programm, i.e. send back KIO3(A) and get KIO3B for $200 I might think about it but not this way. But then what would they do with all the old KIO3's? They didn't offer that option for the KSYN3A, same story there. But we will see, maybe the price tag mentioned was including labour for exchanging the board ... hope dies last. ;-) People always praise Elecraft for having an update path to keep their radios up-to-date while others come out with a Mk2 version where they would need to spend their money twice buying the Mk2 to get the latest features, a.s.o. Now Elecraft came out with the K3S as their "Mk2" ... hear hear! And if I would really keep my original K3 up to date with all the new boards, mods & features I could buy a second radio, too! Don't see much difference to other manufacturers (anymore) ...

Yes, that was me. Thanks for compliment. And I have often cited a program that you probably organized for the EMC group that I think was called Tales From the Trenches, or something like that. It was a dozen or so technical war stories of how each of the presenters solved an interesting problem. I learned a lot from it, and was able to contribute some thoughts to the group about one or two of them. This was one of the very best technical presentations I've ever attended. Right up there with one for the Audio Engineering Society that demonstrated a history of cinema sound at the Academy Theatre in Hollywood, another at an AES Conference in Nashville on all the different kinds of distortion in audio, and a talk at an AES Convention in Amsterdam by Ray Dolby on the history of Dolby. 73, Jim K9YC From kk7p4dsp at gmail.com Sat Dec 19 19:31:57 2015 From: kk7p4dsp at gmail.com (Lyle Johnson) Date: Sat, 19 Dec 2015 17:31:57 -0700 Subject: [Elecraft] KIO3B Audio Spec In-Reply-To: <5675E227.6060001@horizon.co.fk> References: <003001d139f3$f51957d0$df4c0770$@gte.net> <6E012225-A61F-4B6D-AA32-63FD9775C18E@wjschmidt.com> <56755DCE.9040501@triconet.org> <7F199BDA01F3454FAF5FAEE93DD4D1C8@ejhPC> <5675AB06.5000903@necg.de> <00ed01d13aa8$5d1f1590$175d40b0$@erols.com> <5675D960.8030704@necg.de> <5675E227.6060001@horizon.co.fk> Message-ID: <5675F6FD.6010407@gmail.com> The USB CODEC chip is 16 bit.

I believe this is normal. Page 9 of the manual (Transmitter - output power) implies 6 meters will be lower power max, although 106 watts is never actually stated. Based on the statements of a lower max setting for 6 meters in this specification, it would be a reasonable assumption the max power setting would be something lower than 10-160m. Also, when setting CONFIG:PWR SET NOR, 6 meters will operate independent of the other HF bands. Supporting some difference on 6 meters. I actually thought I saw a thread some time ago from Wayne or Eric confirming the difference in MAX power sets on 6 meters compared to the rest of the HF bands, but have not been able to find. 73 Gene N9TF K3S 10057 -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Vic Rosenthal 4X6GP/K2VCO Sent: Sunday, December 20, 2015 7:51 AM To: Elecraft Reflector Subject: [Elecraft] [K3] 6M power setting anomaly This is strange.

Further, the KSYN3AUPG and KXV3B are $220 and $200 respectively, so one might have expected the KIO3BUPKT to be similar. But, in fact, the KIO3/A/B assembly is more expensive than many of us realized. I am confident that Elecraft priced the KIO3BUPKT in the same fair manner as their other products. Each of us can decide if the price is worth the value we expect to receive from it. And, many have already chosen to buy the K3S rather than upgrade a K3. It's great that we have all these choices!

This is not a single board. It is a three board set that costs much more than our old KIO3B to manufacture. The board set also now contains a new USB Codec, USB Comm port, Internal USB hub and additional logic to handle routing of data between the USB and RS-232 paths (all fitting into the same space as the old boards). The upgrade kit also includes two external cables (one custom), new hw etc. These boards are also manufactured at a much lower volume than those in the PC market, with the subsequent increased cost on our end. A $200 price would be selling at a significant loss. Our goal is always to price our products as reasonably as possible after taking into account our production and support costs while making enough profit to continue to exist and serve the amateur radio market.

I don't think my cost was all that much different as I found a buyer for my K3 with all the upgrades I had put in over the years including the sync board. I have now used the K3s for 2 months and while I don't know that I have worked anyone I could not have worked with the K3 I am impressed with how well it works under poor conditions. I appreciate getting rid of the external pre amp, the external sound card and the USB to RS232 interface. I find it easy to use FLDIGI now. When I had all those wires behind my K3 I needed a day of warning before I could do a digital sked. The sync board made my K3 a top notch performer to sell and it is no different than when I put $3000 in my 12 year old car than had another major problem and decided to trade it in. I have never been sorry and now 5 years later still enjoy the new features of my new car. I hope next time around I get smart quicker and do not put $3000 in this 5 year old car before I trade it off but I do hope to keep driving it a few more years.

What are the characteristics of the inputs of your external device? The K3 band data outputs have pullup resistors to provide +5 volts or zero volts to an external device. If that device requires +12 volts and zero volts, it will not work. I might also point out that some early K3s do not have pullup resistors internally, but provide an open drain output. Those need external pullup resistors to +5 volts in the external device or installation on the internal resistors in the K3 - the internal resistors are documented as part of the K3ALC Mod. Do you have any other device (such an the KPA500 or other amplifier) connected which also wants to use the band data lines. That can complicate the addition of another device on the band data lines. 73, Don W3FPR On 12/21/2015 8:20 AM, Charles Yahrling wrote: > hello all and merry xmas! > > For various reasons I need to interface an external device with Band Data > from my k3-100 via the ACC port.

You are probably set for the wrong transmission mode, or have narrowed the IF bandwidth settings. Use Digital A for all computer-generated and decoded modes except RTTY.

The K3 and KX3 seem happy then. 40 amp hours at 12-13 volts should last 4 hours key down. I don't usually last that long. But the charger QRN is about S2 so you could conduct tag chew QSOs while recharging. My approach is to have a backup ready. YMMV -- Marc.

That's the first one I bought from them at the summer sale, and I did complain right away. Those are ideal for powering the KX3 and I carry one in the Pelican with my bare KX3. The USB port is used to power a plug-in LED lamp. I do wish more people making those power supplies could read English. I'd send them a copy of Parts 15 and 17 to read. It's going to take a concerted effort for all 170,000 of us U.S. hams to convince these people. I even had to hand a cheap transistor radio to a rep from our electrical service company to he could listen to the LED power supply he planned to install. He was surprised.

We were running a 100 Watt HF radio from early morning to sunset at 100 watts output. In all our activations, we have not come even close to depleting that battery, less than 20 AH were put back into the battery on charge. Those IOTA events generate large pileups and hundreds of QSOs over a period of about 8 hours. I've also run a K3 on Field Day, at our GOTA station, for 16 hours out of the 24 hour period using a LiFePO4 battery. During that time hundreds of QSOs were made at 100 watts. At the time I was using a 60 AH battery, and the current consumed was 34 AH. It certainly helped that the K3 has low RX current as well. GOTA is not as demanding as a full blown CW run station, but it is certainly more than casual operation. Our full blown Field Day run station is run off a 9 AH LiFePO4 battery for a full hour to obtain the Alternative Power Bonus -- In that time, hundreds of QSOs are made, and the battery is more than up to the task. Expect that a hard core contester using a K3 in full run mode will consume about 8 Amps an hour (8AH). A search and pounce station will consume about 2 Amps per hour, and casual operation will consume about 1 Amp. All at full output. 73, Bob, WB4SON On Mon, Dec 21, 2015 at 4:20 PM, Marc Veeneman wrote: > Oh, yeah. That's the first one I bought from them at the summer sale, and > I did complain right away.

If you are using SSB mode, there can be other factors involved which are not helpful - use DATA A. 73, Don W3FPR On 12/21/2015 2:36 PM, on4iq wrote: > I am sure someone can inform me, i reinstalled the K3 setup and did a check > on the output , audio output. > To obtain a flat reponse i have to put the equaliser to +16 on the freq > above 1khz, and -16 on the freq below 800hz. > This seems very odd. > Putting the equaliser on 0dB for the full range give a rapid rolloff above > 1KHz. > > I want to get a flat response for jt65 use. > Any ideas? > From mike at ve3yf.com Mon Dec 21 19:08:51 2015 From: mike at ve3yf.com (Mike VE3YF) Date: Tue, 22 Dec 2015 00:08:51 +0000 Subject: [Elecraft] K3EXREF Ext.

I use a program called SBSpectrum, it shows frequency changes less than one Hz. I note that the K3, does frequency correction in small sawtooth steps of about 1/4 to 1 Hz, across a few seconds of time, repeatedly... It is as if some threshold is passed and the K3 then instantly jumps to a corrected frequency, and then the process repeats...

By doing this I was able to reset the clock and start all over again with a brand new rig with all the upgrades and a full year's warranty to boot. ?You can save even more by moving your sub RX from the old rig to the new rig -- the Sub RX is one item which did not change. Put your old price list and the new price list side by side and you will see that most items have not increased all that substantially compared t the benefits you receive when upgrading. ? Re: [Elecraft] KIO3B pricing (was: Re: K3IOB) Eric Swartz - WA6HHQ, Elecraft?Sat, 19 Dec 2015 13:00:04 -0800 Also note that the KIO3B has all of the original KIO3 analog and digital functionality and HW. Adding the usb sound and USB data hw to that did not increase the end price by over $200.Lastly at ham radio market volumes, which are much lower than most consumer products, the cost to develop and support any design is folded in the price we must charge over time.

It's worth understanding how well you hear a given signal in typical conditions: white noise with a mix of other interesting audio phenomena. Whether consciously or unconsciously there is always the question of your own hearing abilities versus the receiver. Knowing your own performance envelope can help you gain insight into how best to adjust your receiver to accommodate your own needs. I also think list moderation is Eric's job. Thus, your comment seems to be a tad bit out of line. David - thanks for bringing this at least to my attention. I found it useful and interesting. 73, Doug -- K0DXV On 12/21/2015 8:21 PM, David Ahrendts wrote: > Nope. I?m in the evil, ugly TV news business.

Jim showed me how to get around 30 dB EQ range, I just have to run the AF Gain higher, and it works. My hearing aids are fantastic, they came from the VA and I am truly grateful to the US taxpayers, they, and several of their predecessors have changed my life for the better. They run at afterburner roar, or so my wife says. They even talk to each other ... if one decides it's time to switch "programs," the other follows immediately. I did the test, failed miserably, which wasn't a surprise. :-) Every time they stuff me into the little silent booth, part of the test includes speech in noises. I'm a basic failure on SSB in a contest but my K3 has been the best receiver I've ever had on phone. For those who might be facing gradual hearing loss, a test like this can make a big difference for you.

If you don?t have it, count yourself lucky. You are so right about that. My wife and I both have tinnitus - hers is much worse than mine.

First, I want to thank everyone who offered suggestions, most of which I tried to follow up. After numerous failures, I managed to lure a local guru--a ham who makes his living getting RF and audio things to work. After ten minutes of BS in my ham shack, he said to start disconnecting each wire from the back of the K3, one-by-one. Some of you may have told me to do the same thing, and I remember approximating that, but somehow I must have messed up. At any rate, as soon as we disconnected the line from my outboard USB sound card to the rear input of K3, used for digital work, the audio RFI went away. My friend says he thinks that an isolated line would be better, but the fact that I have a stereo output going directly to the mono input is probably the real culprit. At the moment, only hours since his discovery, I have successfully worked on 80 and 40 meters with the amplifier, but I have not yet fixed up an isolated digital line. My thanks to the entire K3 community who attacked this problem. I am now using the original vertical, fed with patched lengths of hardline, with a hardline, wound choke at both ends. Each choke is 40-50 feet long. I also discovered that my RF ground point in the shack (back of the Ten-Tec KW tuner), shows 30-50 ohms resistance vis-a-vis the electrical ground terminals in the shack. Another rod as part of my RF ground system may be forthcoming. 73, Jan, KX2A From w3fpr at embarqmail.com Tue Dec 22 20:57:48 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 22 Dec 2015 20:57:48 -0500 Subject: [Elecraft] RFI in audio chain In-Reply-To: <5679FBA0.2040305@windstream.net> References: <5679FBA0.2040305@windstream.net> Message-ID: <5679FF9C.8010201@embarqmail.com> Jan, That 30-50 ohms resistance may be a shack safety problem. Your shack ground rod must be connected to the Utility ground rod by a heavy conductor (#6 minimum, but #4 preferred). That ground is only for AC safety and some part of lightning protection. It does not present an effective RF Ground. To use an example, consider an 8 foot connection to that ground and think of a 10 meter signal. That 8 foot connection is about 1/4 wavelength, so while the impedance at the ground rod may be low, the impedance to 28 MHz RF at the shack end is quite high (due to the properties of antennas and transmission lines). In other words, what you are viewing as an 'RF ground' at 10 meters is instead exactly the opposite, it is a high impedance to RF at 10 meters. The proper place to solve RF problems is in the antenna field, and not by attempts (sometimes futile) to bond things to a driven ground stake. 73, Don W3FPR On 12/22/2015 8:40 PM, Jan Ditzian wrote: > > > I also discovered that my RF ground point in the shack (back of the > Ten-Tec KW tuner), shows 30-50 ohms resistance vis-a-vis the > electrical ground terminals in the shack.

I discovered last night that I have the following situation. When in SSB mode on 160 Meters and the 2nd RX is turned on, the SSB signals are on the same frequency. When I invoke the diversity mode, the 2nd RX is receiving at 1.5 kHz higher. I tested this on numerous signals and at various frequencies; always the same. In the CW mode the problem does not exist. In diversity mode the CW signals in both RXs are on the same frequency. Anyone with an idea of what is happening here. I do not remember this happening before. RIT is off. I did not try other bands as I normally do not operate on other bands. I have searched the archives but have not gotten a hit on anything like this. Any responses, direct or to the reflector would be appreciated.

It uses the K2 as the weight to hold a KXPD1 paddle so there is plenty of weight without needing to have heavy paddles. You can see them at: http://www.elecraft.com/KX1/kxpd1k2.htm It was designed to hold the KXPD1 paddles, build for the KX1 which are very nice, but not mechanically adjustable. You might also think about making something similar for the KXPD3 paddles, but the design would need to be very different. There are lots of other light-weight paddles available, but it sounds like you are one of the heavy-handed users that Wayne ran into while alpha-testing the original KXPD1-K2 design; they kept knocking the bracket off the tilt stand. That would mean you need a method to hold them down. I would also recommend one of the paddle sets from Palm Radio. I also own a set of their mini-paddles and like them a lot. I That model is sturdy enough to clamp down with an ordinary C-clamp. I built a foldable wrist-rest attachment, using plexiglass, that allows me to hold them in place by resting the wrist of my sending hand on it to hold them in place. That makes for nearly infinite orientation options with minimal weight. Good luck with your search. 73, Fran > On Dec 23, 2015, at 08:42, Dauer, Edward wrote: > > Seeking suggestions about a CW iambic paddle for the K2.

This upgrade Includes: KIO3B 3 board set (KIO3B main, digital and audio boards), RJ45-RS232 cable, USB cable, h/w and manual. Its can be found on our order form at: http://www.elecraft.com/elecraft_prod_list.htm#kio3bupkt (There is also a link to it on our order page table of contents.) See our KIO3B Upgrade FAQ for details: http://www.elecraft.com/manual/KIO3BUPGD-FAQ%20rev%20A.pdf === The new KIO3B (standard on the K3S) adds high performance USB sound and comm port capabilities to the K3, eliminating the need for RS232 and 3.5mm analog audio cables to the PC. Basically one USB cable to the PC (included with the KIO3B) handles this all, eliminating both RS-232 headaches and potential RFI issues with analog audio paths. The KIO3B also includes all of the analog and digital capabilities of the prior KIO3 (Line in/out, headphone, mic, Aux Conn. and RS-232). If you are using an existing P3 with the upgraded K3 and KIO3B, you will also need to purchase the CBLP3Y, which provides a path to the P3's RS-232 connectors from the RJ45 jack on the KIO3B, and supports one USB cable connection between your PC and the K3 for all comm port I/O and audio. (New P3s are shipped with this cable.) The KIO3B still also supports all of the old methods for rs-232 connections between the K3, Computer and P3, so you can just drop it in to your current hook up without using the USB comm port, if desired. The KIO3B Upgrade FAQ linked above has diagrams showing these two main ways of connecting the KIO3B to the P3 and computer. 73, Eric /elecraft.com/ From ron at cobi.biz Wed Dec 23 19:20:27 2015 From: ron at cobi.biz (Ron D'Eau Claire) Date: Wed, 23 Dec 2015 16:20:27 -0800 Subject: [Elecraft] P3 Turn on Blinding Flash In-Reply-To: References: Message-ID: <001b01d13de0$e43e93d0$acbbbb70$@biz> The display uses an LED backlight so nothing is being stressed. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Steve Ellington Sent: Wednesday, December 23, 2015 11:24 AM To: elecraft at mailman.qth.net Subject: [Elecraft] P3 Turn on Blinding Flash Just wondering: My P3's 12v DC comes from the K3.

Basic interfacing should be like any third-party amplifier. For full integration, a la KPA500, check the manual to see if it will decode band data or do RF-sensed band switching. If not, you'll have to switch amplifier bands manually. Maybe another responder will know. You ask about SO2R and on that I do have some feedback on the SPE amps and it's important. I looked into SPE's claim to support SO2R with a single amp, something I've always fancied but never achieved. IMHO, the implementation is brain dead. The amps have two rig connection, six antenna connections, and a Rig 1/2 toggle input, which looks great on first glance. But the switching connects the non-transmit rig to a special, dedicated, receive-only antenna port labeled, ingenuously, "SO2R!" That means you can't receive on any antenna that is ever to be used to transmit. You effectively need a separate antenna for all reception on whichever radio is not transmitting and if it's not an all-band antenna, you need external switching among multiple, dedicated, receive antennas. Example: six monoband antennas connected to Ports 1-6 on the amp. You can transmit on Rig 1 or Rig 2 and the amp will automatically select the band-appropriate antenna and connect it to the transmitting rig. But it simultaneously and irrevocably connects the OTHER rig to the separate "SO2R" antenna port. Maybe you want to do all such receiving on an all-band vertical? I couldn't believe this when I read it so I called the importer and they confirmed that cockamamie design. Of course, TWO Expert amps will work fine in SO2R like any other amps, one connected to each rig. Use external antenna switching via something like a Six Pak connected to the two amps' ANT1 connectors. Pity, all that internal switching going unused.

The user manuals http://www.expertlinears.com/products.html do have the information to wire a cable to interface the K3(S) with the amp. They apparently have someone that will wire a cable up for you, as noted on their home page. It seems like a very simple build, though. Here is a YouTube video I found interfacing the 1.3K-FA with the K3S and a computer. Interesting that you need to select "Kenwood" in order for the amp to read the correct frequency from the K3S: https://www.youtube.com/watch?v=3rEKUbMuVKc However, they may have updated the amplifier firmware since this video. I saw the last post on SO2R, with the requirement of a receive only antenna. That seems a bit problematic.

One thing though, never use the Expert 2K FA into an antenna with SWR close to 2:1 without the antenna tuner or you will have a very broad signal on either CW or SSB. The solution is simple use the antenna tuner. I learned this when using my SteppIR trombone for 30/40 on 30 meters. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Roy Koeppe Sent: 24 December 2015 13:03 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3/2K-FA int.

But the switching connects the non-transmit rig to a special, dedicated, receive-only antenna port labeled, ingenuously, "SO2R!" That means you can't receive on any antenna that is ever to be used to transmit. You effectively need a separate antenna for all reception on whichever radio is not transmitting and if it's not an all-band antenna, you need external switching among multiple, dedicated, receive antennas. Example: six monoband antennas connected to Ports 1-6 on the amp. You can transmit on Rig 1 or Rig 2 and the amp will automatically select the band-appropriate antenna and connect it to the transmitting rig. But it simultaneously and irrevocably connects the OTHER rig to the separate "SO2R" antenna port. Maybe you want to do all such receiving on an all-band vertical? I couldn't believe this when I read it so I called the importer and they confirmed that cockamamie design. Of course, TWO Expert amps will work fine in SO2R like any other amps, one connected to each rig. Use external antenna switching via something like a Six Pak connected to the two amps' ANT1 connectors. Pity, all that internal switching going unused.

Be careful ... the 1.3KW uses transistors rated for maybe 1000 W CW. SPE's own IMD measurements were done at 800W and were marginal there!

I contacted Elecraft and they couldn't figure it out either. They were fully prepared to ship me an new set (Matched). Over the weekend I was doing some re-wiring of cabling and found that the original 4 cables that I was using were not up to par, could have been purchased offshore. I replaced the 4 cables with ones made in NA and the speakers worked perfectly. So for anyone having speaker problems, definately check out the cables. In my case I didn't use the supplied cables as they were not long enough for my situation. But excellent support from Elecraft on wanting to ship me out a new set of speakers. I also found that the original cables that I was using checked out ok with a meter, but once in the circuit they worked like crap. 73 De Mike VE3YF http://www.ve3yf.com [http://www.ve3yf.com/] From mike at ve3yf.com Thu Dec 24 09:43:09 2015 From: mike at ve3yf.com (Mike VE3YF) Date: Thu, 24 Dec 2015 14:43:09 +0000 Subject: [Elecraft] K3: External Macro Launcher (Revisited) Message-ID: <53407f4c-7b30-4c06-b446-b36839e0ec19@getmailbird.com> In?February?of this year, there was talk of using a?Genovation CP24 Serial Keypad which would allow either 24 or 48 macros to be stored on the keypad and just hit the applicable key and send a macro to the K3.

Speaker cables/connectors need to be very low resistance. One point of issue is machine-crimped pins in a connector that grab insulated wires and penetrate the insulation. It's possible for the pin crimping to contact only a few strands of the stranded wire and pass automated continuity checking but be entirely unsatisfactory for the low R speaker use. Also a bit of patina on a pin or mating surface can do the same thing. Glad you found it before you sent 'em back. That's sooooo embarrassing. I tore apart an amp once, in the middle of a multi-multi contest effort, where the problem turned out to be the RCA plug on the cable for the amp's relay connection. That was sooooo embarrassing. 73 and happy holidays, Guy K2AV On Thursday, December 24, 2015, Mike VE3YF wrote: > I received my pair of SP3's last week and I also had a problem, where I > could get stereo but 1 spkr would always be weaker in audio than the other. > I contacted Elecraft and they couldn't figure it out either.

Mine does the same thing, but since I have my P3 set to power up when I turn the power supply on and before the K3, I'm looking at the power supply when it turns on so I never saw it before today. It's part of the power on sequence. I don't find it bright enough to be annoying at all. It certainly hasn't hurt the P3 in 5 years of daily operation though.

It was OK but became two boxes by the time I had a decent external soundcard. I detested the then available PowerSDR software. Probably better now, but I use an SDR-IQ and SpectraVue* software. Interfaces perfectly with the K3/K3S. Gives both a spectrum and waterfall display, point and click tuning and demodulation if you like (I don't). The software knows all of the K3 i-f offsets and corrects the frequency display automatically. I have two of them, one on my K3 and another on the K3S. The SDR-IQ is out of production now but used ones show up frequently. It's been replaced with the Cloud-IQ which is double the price of the going rate for an SDR-IQ. The Cloud-IQ uses Ethernet instead of USB so I'm unclear about interfacing with the K3, even though SpectraVue is still used. I use LP-Bridge for USB port sharing between my logging programs, the SDR and the K3s. *SpectraVue is to me, straightforward. I have yet to find any other SDR software that is easily understood and used by a normal human being.

Here's an image from an LP-PAN/NaP3 panadapter that I used a while back on an Orion: http://www.tentecwiki.org/lib/exe/fetch.php?cache=&media=orionpan3.jpg The big issue is whether you want to deal with the computer interface side of LP-PAN/NaP3 and the necessary port-sharing if you also want to use a CAT-connected logging program. You'll also need to get all the settings right in NaP3 for the panadapter calibration to be accurate in all modes. The big advantage of NaP3 over other LP-PAN software options is the integral telnet connection that will paint a bandmap superimposed on the spectral display. 73, Barry N1EU On Thu, Dec 24, 2015 at 11:47 AM, Juliean Galak wrote: > I'm planning on getting a K3s and am wondering about panadapters.

Cheaper. $300 - $500 2. Better resolution potential but depends on which SDR or sound card you choose. 3. Point and click with mouse 4. Band changing from screen Computer based disadvantages: 1. Cabling complexity i.e. external sound card + LP-Pan. Sound card can be eliminated with a Fun Cube Dongle. 2. Total dependency on computer. 3. Requires a serial port which mandates using a virtual serial port program such as LP-Bridge is you want to use a logging program at the same time. 4. Computer must be fast enough to keep up with NAP3's requirements. I use a quad core, I7 and 12gb of ram. You could do with less but I know this works. This will certainly increase the CPU load on your computer. 5. Unless you have 2 monitors you will be constantly frustrated wanting to see both your log and pan at once. P3 System advantages 1. Simple connectivity to K3 2. Instant bandscope by simply turning on the K3. 3. Eliminates the need for any computer or software. You really need to experience this to appreciate it. NAP3 is no longer supported by the author and is not bug free. 4. Easy interface to a large screen monitor...Even your 65" TV will work via the optional SVGA adapter. Note: Not all monitors have VGA inputs therefore the P3 may need an adapter. I use a VGA to HDMI adapter. P3 Disadvantages: 1. Expensive $700 to $1000 2. Point and click but requires cranking a knob on the P3...I usually just tune the K3s manually instead. Like I stated above....I'm relieved to no longer depend on the computer. There was always something needing attention and software was really a pain. I've learned to live the the P3's shortcomings. Now all my computer needs to do is run the logging program. BTW: I use Logger32 and it allows using your mouse wheel for tuning anyway.

You're forgetting the cost of the computer and the sound card. My experience has been that NaP3 and other SDR software burns a fair amount of computer horsepower. Many of us use a vintage computer in our shacks for general logging, digital encode/decode, and contest logging.

Back in 1980 I was beginning my new career as two-way radio tech working in a BLM radio shop (had been mw engineer in old career in CA) and asked help troubleshooting from a "50's oldster". He told me that most new-young techs make the mistake of looking for high-tech problems when most "troubles" are simple. So check: 1. power source; signal input/output - first (that includes cables and connectors)(and test equipment-meters) 2. Control settings (pilot error stuff) 3. Look, Feel, Sniff (often the problem will be very evident to those senses)(that hot blackened thingy) 4. Then get out the schematic and repair manual 5. Call customer service (not always step five). Of course if you ARE customer service then ask the "old guy" ;-) Just yesterday two old trusted test cables went "open ckt" and a trusted coax went high SWR. My spectrum analyzer that "seemed dead" had a switch in the wrong position. If voltages seem wrong check the ground wire.

Software is NaP3v4. The screen [for all applications] is a 21" LG. The computer is an DIY AMD 2.1Ghz cpu, 2G ram, running Win7-64 [it's pretty long in the tooth]. I use a microHam CW keyer interface with its Router port-sharing software. Contest logging is N1MM. So... The choice of LP-Pan is dictated by space requirements; no room for another box at the operating position. So, my choice is not based on A-B comparisons/performance. Otherwise, all K-line station. I have never had any problems with the computer supporting LP-Pan and its software, N1MM, and browser all at the same time. I can fit all of the necessary and desired optional windows for all software on the screen during a contest. NaP3 has never given me any trouble albeit it's no longer supported by its author. No question that getting LP-Pan setup and running is more demanding than the P3 which, so I hear, is pretty much a turnkey operation. That said, once online, the LP-Pan setup is stable and runs constantly throughout a 48hr contest without a hitch. In contests, I run the NaP3 display at around 14"x4" on the LG monitor - very pretty and helpful. Some use a dedicated monitor for their panadapter; however, I have not found that necessary to provide the info that I "need" during a contest. Issues of cost are an individual matter. How one balances all these parameters is, again, an individual matter. Either way ends up with a useful tool. I can't imagine operating without a panadapter at this point. So, prepare to get "hooked." ...robert On 12/24/2015 16:47, Juliean Galak wrote: > I'm planning on getting a K3s and am wondering about panadapters.

I recently had a K2 on the workbench recently and observed that the receive response was not as good as expected. I connected it to my signal generator which verified the poor response. Then when turning the K2 on its back to do some probing, all the problems when away. Bottom line was that I had a bad coax jumper in my assortment of BNC to BNC jumpers. Wiggling the ends of the coax revealed which end it was and that end was immediately cut off. BTW, it showed no problem in transmit, only receive. Bad cables are often the culprit when experiencing a problem. Before digging into the equipment, check the cables. That will fix the problem in 75% or more of the cases. Build your own experience base and stow it away in your brain for later occurrences. 73, Don W3FPR On 12/24/2015 5:29 PM, Edward R Cole wrote: > Experience! > Back in 1980 I was beginning my new career as two-way radio tech > working in a BLM radio shop (had been mw engineer in old career in CA) > and asked help troubleshooting from a "50's oldster".

I'm looking for information from other T1 Automatic Antenna Tuner owners ----> A couple months ago I built a SoftRock RXTX 1 watt transceiver to use as a WSPR sending and receiving rig. My intention was to use it on at least 20 and 30 meters, with the WSPR software doing "band hopping". The WSPR software, when set to do band hopping, can be made to send a few seconds of continuous tone RF so an attached antenna tuner could do it's thing before the WSPR stuff is transmitted. The antenna I use is an 88 foot long doublet fed with 600 ohm ladder line. Obviously this antenna needs to be used with a tuner. I purchased the Elecraft T1 for this purpose. I was under the impression that the "automatic" part of the T1 meant that it would recall L/C values from memory automatically, so that when the WSPR software changed bands on the SoftRock and the radio sent out it's tuning signal, the T1 would see the RF frequency and automatically set the recalled L/C values. Mine does not. I am testing the newly-built T1 with my KX3. Here is what happens: First, I put the T1 into auto mode, and then I set the KX3 to a frequency on 20 meters and make the T1 tune. This works fine; my SWR on the KX3 goes from ugly to 1:1. Then I go to 30 meters and do the same thing. If I now put the KX3 back on 20 meters on that exact same frequency and press my key, I have the ugly SWR back again. I thought this tuner would recall the previous setting when it saw that 20 meter RF. But alas, it does not. So, my question is - have I messed something up in building the tuner, am I doing something wrong in my procedure, or have I bought myself a Christmas present I can't use?

That would have increased the size and cost of the tuner. It does, however, have remote-control capability, as described in the manual. You can send a simple pulse stream to the T1 to go to a given band (160-6 m) and recall the last-used settings. A microcontroller or PC program could be used to create the pulse stream. You should only have to tune up once on each band, assuming you don't change antennas. 73, Wayne N6KR (Taking a brief break from Christmas wrapping) On Dec 24, 2015, at 8:50 PM, James Bennett wrote: > I hope I haven't made a $150 mistake.

Unfortunately, it pretty much means that it is actually a ?semi-automatic? tuner.

I?ll investigate the feasibility of user mods to WSPR, but not holding my breath at this point.

The Com port number needs to be the same in WriteLog as in the K3 USB port on your PC. There are no isolation transformers because the audio in and out of the K3 is digital via USB. Your PC will now list an additional sound card which is the K3. Select that sound card for your mic input. When you first connect the USB cable between the PC and K3, Windows will find the USB and Codec drivers and install them. Wait for that standard Windows process to complete. Then you will have an additional Port device called USB something in Device Manager. Under Soundcards, there will be a new Codec which is the K3. If you are using one PC for SO2R with two K3s, then the PC will show two new soundcards, one for each K3. The PC will also show two new Ports, one for each K3. As far as knowing which soundcard and port go with which K3, only plug one USB cable in at first and note which Com port it installs with. Change that Com port number if you wish, but remember what it is for that specific K3. Go into the Soundcard section of Device Manager and rename the K3 soundcard to something like "K3-right". Then, plug in the second K3 and repeat. If you ever get confused, just unplug one of them and see what remains. No splitters or isolation transformers are needed. That is the whole point of the KIO3B. ;>) Ed W0YK -----Original Message----- From: WriteLog [mailto:writelog-bounces at contesting.com] On Behalf Of Ken Widelitz Sent: 24 December, 2015 21:21 To: elecraft at mailman.qth.net; writelog at contesting.com Subject: [WriteLog] Using K3 KIO3B USB with Writelog What Port Settings would I use in Writelog to grab the frequency from the Elecraft K3 using the new KIO3B USB connection?

See the URL: http://www.omnia-sdr.com/index.php?main_page=index&cPath=65 This radio covers up to 4 bands instead of just two, costs only slightly more than the Ensemble TXRX, is the same form factor as the Ensemble, requires no sound card, is compatible with all SoftRock Si570 control software, and, it directly connects to and commands the Elecraft T1 tuner. Another poster made a comment regarding the possible incorrect choice of the Elecraft T1 autocoupler for a particular application. One might instead consider that the T1 is an ideal choice, and then select a radio that works better as an integrated-system element. 73 Steve KZ1X ______________________________________________________________ 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 km4ik.ian at gmail.com --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From inventor61 at gmail.com Fri Dec 25 10:28:11 2015 From: inventor61 at gmail.com (inventor61 .)

That's true only in so far as the USB device does not have a unique serial number. The USB device descriptor in the EEPROM has a place for a serial number but many manufacturers do not make use of it. If the device is "numbered", it can be moved from port to port and the virtual COM number will not change. Unfortunately, many hardware manufacturers do not take the time to provide/program a hardware serial number before shipping their products - they rely on the chip maker's default device descriptor and drivers. 73, ...

My plan is to simplify digital interface cabling by replacing a MicroHam USB Interface III with the newly released KIO3B boards for the K3. My assumption is that the KIO3B's USB port will handle both audio and PTT control when using AFSK. Also, will the new KIO3B allow for FSK keying with no additional hardware or cabling to the K3's ACC connector? Has anyone experienced any USB connectivity issues that might justify keeping the microHam USB interface and existing KIO3A board? Merry Christmas to all!

THANK YOU! As I have neither seen nor owned one of these keypads yet, I assume one must program each key to emulate a key on a keyboard, separately first. So to check my understanding here is a brief overview: I program the Genovation, using a PC to have a few buttons emulate a few ASCII keys, and unplug it, and set it aside. I then use a normal ASCII keyboard, jacked into the USB port of the P3 to program a few macros, using teh same keys as triggers I programmed into the Genovation. I then remove the ASCII keyboard, and replace it with the Genovation keypad, now if I press one of the pre-programmed keys, (and that key matches a key I have pre-programmed into the P3), the macro associated with that key will trigger, thus controlling the K3, or P3. Is that even close to correct? If so I order a Genovation today! -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info For MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Fri, 2015-12-25 at 14:13 -0500, Joe Subich, W4TV wrote: > On 12/25/2015 1:26 PM, Jim McDonald wrote: > > Note that Fred said a P3 with the SVGA option. > > In which the Gennoation USB/HID version should work in lieu of a > keyboard as long as you know the keystroke equivalents to program it. > > 73, > > ...

No. The KIO3B does not support FSK - you still need a separate FSK signal connected to the ACC connector. > Has anyone experienced any USB connectivity issues that might justify > keeping the microHam USB interface and existing KIO3A board? The KIO3B hardware (hub, FTDI UART, and PCM9203E CODEC) are essentially identical to the microHAM USB Interface III. However, the KIO3B lacks an FSK output, does not have software that allows mapping the RTS/DTR lines to a separate virtual ports (e.g. MMTTY with CAT on one port and FSK/PTT on another) and it does not support tone based FSK (pFSK) or CW (qCW) like USB Interface III. With the KIO3B one needs a separate source of FSK and PTT independent of the UART in the KIO3B. 73, ...

I have the KAT500 Autotuner to go with my K3 and KPA500. Also have the internal tuners for the K3 and my KX3. I was thinking that the T1 would act in a similar manner, since it IS called an Autotuner. But that part of it isn?t auto!!! After reading Wayne?s reply last night my first inclination was to put the T1 up for sale and look elsewhere for something that would work with the SoftRock and WSPR for multi-band use. But I?ll hang on to it for now and see what I can do. My WSPR software is not able to make the SoftRock send any sort of band/freq signal to the T1 - only a burst of RF, so the T1 WILL work with my setup, but not exactly in the manner I was hoping. Adding more outside wires is a problem for me, as we are in a HOA/CCR restricted area and I?m not supposed to have any antennas out there at all. As it is I have the doublet, an 80 meter Inverted L, a 160 meter Inverted L, a ground mounted Hustler 5BTV, and a 144/440 ground plane for local repeater use. I?m really pushing it with all that stuff, although most is fairly stealthy. Someone suggested trying the Peaberry, but it is no longer in production. It?s successor, the Omnia SDR very well may be what I need to use instead of the SoftRock. It?s slated to be available some time in January and I sure hope to get one soon after they are out. I?ll use the T1 in conjunction with my SoftRock and WSPR, but un a semi-automatic setup for now. 73, Jim > On Friday, Dec 25, 2015, at Friday, 7:00 AM, Ray Sills wrote: > > HI Jim: > > I saw Wayne?s response to your inquiry. My guess is that it?s easy to assume that the ?auto? capability that -is- part of the larger tuners the Elecraft offers (like those for the K3S, and the KPA500) also applies to the T1.

My intention was to use it on at least 20 and 30 meters, with the WSPR software doing "band hopping".

Software is NaP3v4. The screen [for all applications] is a 21" LG. The computer is an DIY AMD 2.1Ghz cpu, 2G ram, running Win7-64 [it's pretty long in the tooth]. I use a microHam CW keyer interface with its Router port-sharing software. Contest logging is N1MM. So... The choice of LP-Pan is dictated by space requirements; no room for another box at the operating position. So, my choice is not based on A-B comparisons/performance. Otherwise, all K-line station. I have never had any problems with the computer supporting LP-Pan and its software, N1MM, and browser all at the same time. I can fit all of the necessary and desired optional windows for all software on the screen during a contest. NaP3 has never given me any trouble albeit it's no longer supported by its author. No question that getting LP-Pan setup and running is more demanding than the P3 which, so I hear, is pretty much a turnkey operation. That said, once online, the LP-Pan setup is stable and runs constantly throughout a 48hr contest without a hitch. In contests, I run the NaP3 display at around 14"x4" on the LG monitor - very pretty and helpful. Some use a dedicated monitor for their panadapter; however, I have not found that necessary to provide the info that I "need" during a contest. Issues of cost are an individual matter. How one balances all these parameters is, again, an individual matter. Either way ends up with a useful tool. I can't imagine operating without a panadapter at this point. So, prepare to get "hooked." ...robert On 12/24/2015 16:47, Juliean Galak wrote: > I'm planning on getting a K3s and am wondering about panadapters.

I don't know the T1, but... The WSJT programs are all open source, so you can do anything you want/need to do with them, subject to tools and skills availability of course (the latter is often the stumbling block for most of us, sadly.) The SoftRock kits: The embedded micro controller they use for USB<>I2C work, may have a spare pin or two, or you can hang another I2C I/O chip on the I2C bus (a PCF8574 for example) to get generic digital I/O ports. I've done that to control a bank of band filters between the antenna and a SoftRock here. The hardware was fairly simple, re-engineering the software however, is an "ongoing" project... The other way might be to check out what Hamlib has hiding, as that is used with the WSJT programs for rig control. Maybe, there is something in there that can send simple one byte values to a simple UART IC, that you can then pull some identifying code from, to poke the T1 tuner to change bands. Sadly, Hamlib on Windows is usually embedded in the main program, so you're stuck with what it has already. With the KX3 (+ K3, and other Kenwood remote like radios) you can also put the rig into AutoInfo mode, where it will spit out (among other things) the working frequency periodically, and when things change. There are other kits and products about, that can decode that info, and set/clear a small array of I/O bits, specifically for changing antenna's, and kicking ATU's into life. It does add to the overall complexity however. There is bound to be a WSJT support list/forum somewhere, you could ask on that to see what may be possible already to suit you needs. 73 & Seasons Greetings. Dave G0WBX.

Unfortunately, it pretty much means that it is actually a ?semi-automatic? tuner. And, since the band changing is being done from within a program K1JT?s WSPR, I have a feeling I?ve got no way to do the remote control stuff per the manual.

However, as I get older it seems foolish for such a wonderful radio to sit unused year after year. So I pulled it out of storage and put it on the air the other day and it works like ?yesteryear?. I had a nice QSO with an Oklahoma station who gave me a nice 559 from Colorado and said it sounded very nice. It?s a true Norcal Sierra All Band Transceiver from 1996. I remember it was a labor of love putting it together and painting the case. I also remember working and reworking the case until it was as perfect as I could craft it. The radio puts out between 1.5 and 3 watts and has a hot receiver. I installed a bar-graph LED Smeter and Wayne?s variable crystal oscillator filter modification. It also includes the original KC-1 cw memory keyed and all the modules 10 through 160. Undoubtable the module could all use a good peaking and the 10 and 160 band modules are unbuilt. The case has nice snap-latches that allow for quick band module changes. The case is in excellent condition but the top and bottom have a few very minor paint nicks. Also included is the original 1996 manual and a reprint of it along with some modification documentation including the KC-1 information. This is a rare radio and one I have treasured so my price is $350 for all. Pictures can be sent if you are seriously interested.

Message-ID: <567EC36E.3070307@bellsouth.net> Group - I'm wondering whether an upgrade to KIO3B would be a step forward or a step backward for me. My current setup, which works FB, uses two outboard USB sound cards. One outboard sound card runs CW Skimmer using a Softrock SDR, K3IF out, and one laptop USB port. The second sound card does digital modes and, having left and right channels, allows me to work RTTY SO2V in N1MM+. It uses the K3 line in and line out ports and a second laptop USB port. A third laptop USB connects the laptop to the K3 RS232 port for radio control and logging. LP Bridge creates the virtual com ports that make the K3 logging software and sound cards work together. I use DXLab for routine logging, N1MM+ for contest logging. My reading of the available info about the KIO3B is that when the USB port in the KIO3B is connected to a radio, the line in, line out ports will be disabled.

Since you already have your system running, and you already have the investment in the soundcard and USB to serial adapter, I would suggest that you not upgrade until those devices fail for you. 73, Don W3FPR On 12/26/2015 11:42 AM, Larry Libsch wrote: > Group - > > I'm wondering whether an upgrade to KIO3B would be a step > forward or a step backward for me.

How would I make my setup work with the > KIO3B? That is not correct. The K3S analog "Line Out" audio goes to both the input of the USB CODEC and the Line Out jack at all times. Connecting a plug to the Line In jack *disconnects* the output of the USB CODEC and uses analog audio instead of the audio from the internal USB sound card (USB CODEC). The USB "serial port" can be used independently of the USB sound card by making the appropriate selections in the configuration menu. You could eliminate one USB sound card (for digital modes) and the USB to serial converter in your SO2V configuration by using the KIO3B but I doubt that you will see any increase in performance if the USB sound card is of reasonable quality. 73, ...

I was thinking perhaps for the weak heterodyne issue, you could use the RX EQ feature. It is a broad brush, but it does have +/- 16dB of range in 8 bands. I tried that and found something rather interesting. The RX EQ is applied *before* the AGC! I never knew that - maybe I'm the only one. Makes sense since the IF is 0Hz - why waste AGC on energy I don't want. Kudos to the Elecraft engineers that thought that though the extra step! The auto-notch feature is great for intermittent tuneups or other (multiple) CW signals in the SSB passband, but it is applied after the AGC. That works well if interferer is equal to or less than the level of the SOI (signal of interest), but for the case where the interferer is much stronger than the SOI, the AGC is dominated by the RFI and can make the SOI difficult to copy. At least the tone is not blasting away in my ear;) But it does present a problem. There is a work-around. Use CW mode to receive the SSB signal, and harness the power of the manual notch. If in a QSO, use split mode to operate SSB on transmit and CW mode on receive with the filters widened and pitch offset removed to receive the SSB signal. Don't forget to turn off split when your done! =:O. I put the KX3 on the bench and measured the CW notch depth using the built-in dBV meter. I measured more than 60dB! If I adjusted the VFO about +10Hz, it was over 90dB!!! How accurate is 90dB?? Well, call it +/-10dB and you still get 80dB min! That is a *considerable* RFI countermeasure. And the best part? It is before the AGC!!! As an experiment, I tuned to 7255KHz where ECARS is active and used a siggen to create a CW RFI in the middle of the passband at S9+20dB. The auto-notch completely removed the tone, but I could not copy the net - S meter still at S9+20dB. Switch to CW mode and adjust for SSB receive. I could completely remove the CW RFI with the manual notch - gone! And the AGC was now totally operating on the signals - noise level was S2, signals were as low as S3. I suppose technically the AGC was noise driven at S2, but that is the point - no RFI. Note: for LSB use CW, for USB, use CWR. This is a really cool thing. I have, on occasion, had the problem of the "antenna matching enthusiast" coming up in the middle of a QSO, and making things challenging...for several minutes. I guess they are going for that last decimal point - and have no need for RX mode:\. Using CW mode and the CW notch in this situation makes it very easy to apply rule #1: Don't acknowledge the presence of the interferer - because they are no longer there! This is especially useful if the RFI is not an "antenna matching enthusiast", and does have RX mode :(.

In-Reply-To: References: Message-ID: <004801d1400f$5b2f5210$118df630$@com> I find it hard to believe that the processor in the KPA is locked up. I've done quite a bit of experimentation with the RS-232 port on it and have never locked mine up and never had the need to attempt a reset? Can you get to the menu of the KPA? If so, it is not locked up. However if you unplug power from the amp and wait a minute to two it may have the same effect. How is the Flex connected to the amp? Are the communication parameters the same if you are using RS-232? When you do attempt to key the amp, is there an asterisk (*) shown on the KPA display? When you changed bands on the Flex does the amp follow? 73, Cliff K3LL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of joeduerbusch Sent: Saturday, December 26, 2015 8:34 AM To: elecraft at mailman.qth.net Subject: [Elecraft] KPA500 RESET??

I did get the KPA500 working. Don't know what I did but I played around with the DDUtil a bit and it started working. The DDUtil acts as a bridge between the Flex and the KPA500. The DDUtil reads information from the Flex and send it to the KPA500. It makes the KPA500 follow the Flex during band changes. It also had a features called AutoDrive that lets the user set the Amp drive and the Barefoot drive. It knows when the KPA500 is offline or off and sets the drive accordingly. I do think it was inhibiting the PTT as even with the KPA500 in OPER there was NO *. Turning off the computer and turning off the KPA500 did not seem to reset the problem. I don't think it is an issue with the KPA500. Joe K0BX #1 Honor Roll Mixed Honor Roll RTTY 5BDXCC Plus 30,17,12 5BWAS Stop the insanity!

To expand: . I set up 20 meters to show S units (LvL Mode=S Units); a Ref Lvl from S0 to S9; Average = 5; Span = 20 khz, and apply that all to FN1 . I then set up 20 meters to show S units (LvL Mode=S Units); a Ref Lvl from S0 to S9; Average = 5; Span = 100 khz, and apply that all to FN2 That all works perfectly, and toggles between FN1 and FN2 is great. But, when I go to any other band: . FN1 and FN2 toggle correctly between 20 khz and 100 khz, the screen still displays S units; and the Average remains at 5. . But, on all bands except 20, where I configured the P3 , Ref Lvl is way off, with S5 displayed at the bottom with +30 at the top of the screen. Desired State: What I would like is for the P3 display to appear the same on all bands. So, is there a way to apply configuration changes globally to all bands, or do I have to manually set Ref Lvl on each band?

Change the band, and it remembers the settings for that band. In the P3, much of this is because what works best on one band may not work all that well on another. The 8 programmable function keys aren't enough for a selection of various options [like 2 SPAN's] and other parameters for each band. Everyone runs it different: For me, globally: Always fixed-tune mode Full-screen shift Spectrum Avg = max WF mode = monochrome WF Avg = min FN1 = 200 KHz span FN2 = 100 KHz span FN3 = 25 KHz span FN4 = 4 KHz span Amplitude scale = dBm I've still got 4 unused FN keys. :-) I use full-screen shift [the whole next span when I tune off either end] I use monochrome WF because I don't have any color vision, however several guest ops whose color vision is normal note that they can spot weaker signals in mono than they can with the color display. I'd recommend you try both. REF LVL: The reference level will change from band to band and from time to time on the same band. It is a reflection of reality ... that's what is really happening on the band, baseline noise [and noise characteristics for that matter] change with time, and we normally like the noise at the baseline. Monitoring signals on the bands, the spectrum amplitude will NOT reflect the S-Meter. You can calibrate it with a signal generator of course, but with max averaging in the spectrum, it won't directly, quantitatively follow the S-Meter. That too is normal. I bought my P3 as a toy never guessing that it would end up being what I look at while operating. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/26/2015 3:03 PM, Ferris Jennings wrote: > I'm configuring my new P3, and have one big question: is there a way to make > "global changes". > To expand: > > .

Message-ID: <201512270130.tBR1UMF7008540@mail40c28.carrierzone.com> Larry, Considering your current configuration is working with the KIO3A, probably easier to stay with it. My situation is a bit simpler as I just run digital modes with DATA-A and the line-in and line-out lines with my USB/RS232 conversion cable connecting RTS/DTR lines to the K3: "Not broken so why fix it?". Having direct USB interface for my K3 offers little inducement to upgrade the KIO3. I have two SYN boards to install which I will use on 630m very nicely and should possibly improve receive due to lower phase noise. So like you, I will defer the upgrade...at least for now. I am sticking with my old XP32 computer and will soon disconnect it from the internet, running exclusively ham applications. My internet/e-mail will be transferred to a laptop which has win10. If/when my old stuff croaks then upgrades may be in order, but my soundcards are not supported by win10 and most replacements do not check out well for my special applications (dual-pol adaptive reception of eme signals in diversity mode). 73, Ed - KL7UW busy working on 2M amps Date: Sat, 26 Dec 2015 13:12:17 -0500 From: Larry Libsch To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Upgrade to KIO3B?

Message-ID: <006801d1404d$9b0d3ad0$d127b070$@gte.net> The bottom of page 30 of the P3 manual shows a photo with the waterfall completely off on the P3 with the TX Mon option. The text immediately above that photo states "Note that in this illustration the waterfall display is turned off so the spectrum display and the waveform display fill the main part of the screen." I see the menu item under SVGA where I can turn the waterfall on or off. I don't see that option for just the P3 display. What I would like to accomplish is have the waterfall on the SVGA monitor, but not on the P3 display.

This device is no longer available from Creative Labs and doesn?t appear to be supported any longer either. I have been looking at the Focusrite 2i2 and trying to compare specs of it with the E-MU 0204. Without having one (the 2i2) in hand, I cannot do a side-by-side comparison. I am thinking of ordering one and seeing if it is comparable to the E-MU 0204. From the looks of and reading about the 2i2, it appears that you could hook two radios to it. I?m thinking the K3 w/ second receiver into Line 1 and the I and Q of the KX3 into Line 2. Line 1 and Line 2 are the Neutrik connectors and I *think* stereo (someone please correct me if I?m wrong) which would allow you to hook up the way I?m thinking. If someone knows about the Focusrite 2i2 (or other product) that is OS X 10.11-capable, please inform the group. I?m looking for something in the $100 - 150 price range. The devices that Jim (K9YC) recommends will work with OS X but not with *all* functionality (i.e. the Sonar U7 will not enable the buttons and volume adjustment in OS X the last I read). On another note, I?ve still not convinced myself that the K3SYNA upgrades are useful to me and my casual operating. I would have liked to gone with the KIO3B except for the price point (about which I am *not* complaining - it is what it is).

After tracking down a manual on the 2i2 it looks like Line 1 and Line 2 are two *mono* channels. You could connect one radio. If you are looking for a four channel device, the 2i4 may be more in line with the E-MU 0204 but not in the sub $100 price range. I have no answer to any of the OS-X related questions - if you can use two radios at the same time, etc. with the Focusrite boxes. An alternative is the Presonus AudioBox series - IIRC, they were a favorite of W7AY with his OS-X systems - although Presonus seems to be 30 - 50% more expensive than the equivalent Focusrite products. 73, ...

I am running multiple instances of WSJT-X (rev 1.6). The TASCAM US-322 should work well also. Both are available at Amazon.com. TASCAM provides drivers for OS-X.

The KBPF3 modification impacts only the 0.5-2.0 MHz section of the BPF3. In essence that section of the filter is converted from an 0.5 - 2.0 MHz BPF to a 0.1 - 2.0 MHz BPF. IIRC when I modeled the modification with filter design software, the behavior above 1 MHz showed little or no change while the low frequency response was substantially better between 100 and 500 KHz. 73, ...

After operating my K2/KPA100/KAT100 for years (and it's still great!) and also operating K3s frequently for contest operation the KX3 quickly became my favourite TRX, at home, on portable contest activities as well as stand-alone on battery power for true portable operation. The receiver is absolutely top performing and shows the power of true DSP designs. Besides implementing great algorithms the Elecrafters know the practical needs of the user community. E.g. receiving crisper clear CW with 50 Hz bandwidth, dual watch or the RTTY with CW input are just unbelievable! Thanks for making this rig happen. Having used my KX3 for about a year some wishes or ideas arose, which I'd like to present to the community. I am aware that not everything can be implemented in the existing radio. But maybe some of my "wishes" can be taken into consideration in future designs. - pushbutton switches Beginning with the K3 Elecraft turned over to rubber pushbuttons. I know these are much easier and cheaper to produce in an automated (SMT) parts placement process, but I still are not happy with them. The behaviour of these buttons varies rather large from button to button. At my KX3 some buttons provide intermittend contact closure resulting in undesired action. E.g. holding BAND+/RCL sometimes results in a number of super-fast band changes instead of recalling a memory. Other buttons work perfectly. Other KX3 or K3 have this issue on other pushbuttons. With the real switches of the K2 I never had this type of issue. Maybe a future firmware release could mask very fast contact closures as a continues hold. I guess no user who intentionally wants to press a button several times would do this with a rate of more than 1-2 presses/second. And maybe on a future rig Elecraft could think about going back to real switches? - recalling memories The KX3 features a vast amount of 100 general purpose memory. That's great. However, while dialling through the memories the receiver jumps to every frequency on display. I tend to sort memories by usage (e.g. beacon freqs) rather than by band. So a lot of time consuming band changes happen. This makes it practically impossible to quickly dial through the 100 memories. I'd like to speed dial the memories without tuning the receiver until I specifically select one memory. If other users prefer the current implementation maybe a one second tuning delay would allow speed dialling the memories while still allowing to temporarily listen to memories. - switching speaker / headphones At home I operate my KX3 together with the PX3. While in QSO I use to wear headphones. At other times I listen using the built-in speaker. As the headphone connector ends up between the KX3 and PX3 it would be nice to activate the speaker without removing the headphone connector. In some operating conditions parallel operation of phones and speaker would come in handy as well. This is not an important thing, but maybe this is possible under firmware control? - CW autodetect With my K2 I really liked the CW autodetect feature for parallel operation of computer keying (contest) and manual paddle keying. This K2 feature is absolutely great, allowing for very easy wiring and enhanced functionality, e.g. different speeds on computer and manually keyed characters. I really really miss this one. Maybe there is some code memory left for this? - Tilt stands The tilt stands of the KX3 are designed to tilt the KX3 while still allowing to operate the KX paddle. However, most of the time I use the KX3 on a table and for this it would be handy to tilt the KX3 front to a higher angle for improved access and readability. I use a 15 cm high strip of wood which gives a nice viewing angle while still providing enough clearance between the lower KX3 edge and the tabletop. Maybe Elecraft could provide longer tilt stands as an option? - CW weighting While I usually operate CW with a nominal weighting of 1, it sometimes would be nice to slightly reduce it to 0.90, especially for higher speeds in contest mode. Could the firmware allow weighting down to 0.90 ? - RX antenna I really miss the receive antenna connection of the K2 or K3. I know this does not easily fit in the portable KX3 enclosure. And on a true portable operation there is usually no need for a receive antenna connector. But as the KX3 is performing that great, I meanwhile use it for all kind of operation. From the practical point of view a receive antenna socket in the KXPA100 enclosure would suffice. While this is the wrong place from a technical point of view, it maybe could be "simulated" under strict firmware control? That's something for the KX4 or a KXPA100 rev 2 :-) - WSPR And finally, my extra dream function: A built-in WSPR beacon! Yeaah, it would be just too great to hike to some nice place and operate a WSPR beacon for some time just out of the KX3. I'm talking about transmit only. However, WSPR decoding could be something for the PX3? :-) Just kidding. Thanks again to all Elecrafters for their work. I hopefully haven't been wasting too much bandwidth here. A happy and prosperous new year 2016 to everyone with great times at the radio.

It is the voltage that matters. The output of the headphone amplifier is a low impedance source which will drive loads of varying impedance. Compare with plugging an appliance into a household AC receptacle - The power company provides a low impedance source, and the power transferred depends on the impedance of the appliance that you plug into the receptacle. 73, Don W3FPR On 12/28/2015 8:10 AM, Barry N1EU wrote: > Is there an acceptable range of headphone impedance for the K3/K3s? > > I've got some 300-ohm headphones and wondering if the impedance alone > makes them a poor choice for my K3s? > > From W2RU at frontiernet.net Mon Dec 28 10:20:26 2015 From: W2RU at frontiernet.net (W2RU - Bud Hippisley) Date: Mon, 28 Dec 2015 10:20:26 -0500 Subject: [Elecraft] headphone impedance In-Reply-To: References: Message-ID: The headphones I have used for over a decade are 600-ohm high-end stereo high-fidelity phones.

As others have told you, it's not an issue. For at least 50 years, audio equipment has low impedance outputs that are designed to work into relatively high impedances. In audio, we don't "match" impedances like we would in RF. Power amplifiers, of which headphone amplifiers are a special set, are typically designed to provide 1V or so into any Z greater than about 100 ohms. Think of it this way. High Z phones are designed to require more voltage but less current, while low Z phones require less voltage but draw more current. The IR drop in the output stage will reduce the voltage to low-Z phones, but they don't need as much voltage to be loud enough. And there will be little or no IR drop to higher Z phones, so they see the full 1V output. Bottom line -- nearly all modern headphones are designed to work with a 1V source. There's discussion of these issues in http://k9yc.com/GroundingAndAudio.pdf 73, Jim K9YC From n1eu.barry at gmail.com Mon Dec 28 13:08:04 2015 From: n1eu.barry at gmail.com (Barry N1EU) Date: Mon, 28 Dec 2015 13:08:04 -0500 Subject: [Elecraft] headphone impedance In-Reply-To: <568177FF.2090900@audiosystemsgroup.com> References: <568177FF.2090900@audiosystemsgroup.com> Message-ID: I believe this also means that the K3 headphone output circuit will deliver 10X power (with fixed V, P~1/R) into a 30-ohm headphone as a 300-ohm headphone, so at some point the amp might clip as you raise the headphone impedance?

I'll take the first 15 or so. If I don't send you the new firmware today, hang in there -- it should be beta in a week or two. Note on 15 W output level: This requires a power supply voltage of 12.8 V or higher on key-down as indicated by the KX3 itself (on the VFO B display). All of the usual firmware protections apply, i.e. the KX3 will roll power back to a lower level if necessary to keep current drain and temperature within a safe range, or if supply voltage is too low. 12 W max is the generally recommended level, so 15 W should be used only when really needed. And again, this is experimental. 73, Wayne N6KR From jim at audiosystemsgroup.com Mon Dec 28 13:16:48 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 28 Dec 2015 10:16:48 -0800 Subject: [Elecraft] headphone impedance In-Reply-To: References: <568177FF.2090900@audiosystemsgroup.com> Message-ID: <56817C90.6010609@audiosystemsgroup.com> On Mon,12/28/2015 10:08 AM, Barry N1EU wrote: > I believe this also means that the K3 headphone output circuit will > deliver 10X power (with fixed V, P~1/R) into a 30-ohm headphone as a > 300-ohm headphone, so at some point the amp might clip as you raise > the headphone impedance? Only if you crank the headphone output too high. My 1V example is simply the maximum sine wave output at clip, and that value is typical. When you turn down the headphone gain, you reduce that voltage. I don't recall the spec for the K3. In your 30 ohm headphone example, you would probably not need to crank the gain nearly as high, so the output voltage would stay below clip. The exception might be if the operator has significant hearing loss, so was driving the headphones very hard. 73, Jim K9YC From steven4lq at gmail.com Mon Dec 28 13:59:09 2015 From: steven4lq at gmail.com (Steve Ellington) Date: Mon, 28 Dec 2015 13:59:09 -0500 Subject: [Elecraft] headphone impedance In-Reply-To: <56817C90.6010609@audiosystemsgroup.com> References: <568177FF.2090900@audiosystemsgroup.com> <56817C90.6010609@audiosystemsgroup.com> Message-ID: K3 uses the.

Amplifier gain control is done digitally within the chip. With such a high Z load, gain would likely need increasing. The results of doing so are unknown. Consider pop, click, white noise etc. Also consider what happens when switching from headphones to speaker when the AF Gain control is turned up high. Blasting? I suggest sticking within the 16 to 32 ohm range.

Certainly a higher impedance load will reduce the power available from the amplifier, but the output voltage will be higher and the current requirement is lower. Most headphones (other than some audiophile types) do not require much power at all. 73, Don W3FPR On 12/28/2015 1:59 PM, Steve Ellington wrote: > K3 uses the. > > LM4811 Headphone Amplifier > > Texas Instruments Specs for output Z > > RL = 16? 105 mW > RL = 32? 70 mW > > At 60 ohms the output power drops to 20 mw.

You?ll find something called ?damping factor?, and it?s often 50 or more. Roughly speaking, it?s the ratio of the (loudspeaker) load impedance to the internal (source) impedance of the audio amplifier. So modern semi-pro and stereophile audio amplifiers are ?grossly out of specs?, as you put it. I have a legacy, hernia-inducing McIntosh power amplifier, circa-1960s, with output transformers and three taps ? for 4-, 8-, and 16-ohm loudspeaker loads. Nothing I?ve owned since then uses output transformers or matched loads. Most audio amplifier designs these days are voltage followers. Most manufacturers don?t attempt to match source impedance to load impedance. Highly damped output stages are ?good? things to have. Yes, it?s true that voltage-follower amplifiers deliver more power to low-impedance loads than to high-impedance loads. But if I were to follow your line of reasoning to its logical conclusion in the home audio arena, I would conclude that 4-ohm speaker systems are sonically superior to 16-ohm speaker systems simply because they require more output power from the audio amplifier to play my music collection. Does that seem like a reasonable way to choose your stereo system loudspeakers? Or headphones for your K3? If your 100-ohm (or higher) headphones can?t provide reasonable levels of undistorted sound pressure at your ears when your K3 or K3S audio gain control is at, say, 9 or 10 o?clock, perhaps it?s time to buy a new pair of ?cans?. That?s certainly gotta be cheaper than reverting to a 75A-4 with its audio output transformer and 500-ohm tap.

Higher impedance headphones (and speakers) have larger voice coils (more turns) than lower impedance headphones/speakers. The larger number of turns produces a larger change in magnetic field for a given change in current. Typically the magnetic field increases as the square of the number of turns while the current in the coil decreases linearly with the impedance. In simple terms, because audio is "low" frequency, doubling the number of turns will increase the magnetic field by a factor of four while increasing the impedance by a factor of two. Thus, although the audio amplifier produces less *power* with higher impedance headphones, the high-z headphones produce more sound pressure per unit of audio input ... the higher impedance headphones will be more *efficient* than low impedance headphones. Where an audio amplifier is relatively limited in power output (e.g., old battery powered "portable" radios) high impedance headphones were the 'phones of choice. 73, ...

That sets compression and equalization to zero, otherwise it is the same as USB. I am not sure why you have MIC + LINE selected, just set the input (while in DATA mode) to LINE IN. I assume you are attempting to use the soundcard built into the K3S - if so, be certain there is nothing plugged into the LINE IN jack on the rear panel. See page 33 of the manual. To set the audio level, put the K3S into TX TEST and you can set the level without transmitting any RF. Adjust the LINE IN level to produce 4 bars solid on the ALC meter with the 5th bar flickering - that is the "no ALC" point for the K3S (ALC begins at the 5th bar). Failure to set the audio to that level will result in the K3S "power hunting" in an effort to maintain the power level you have requested with the power knob. You can use both the computer audio playback slider and the K3S 'MIC GAIN' (it will set the line in level). To change the soundcard settings in Windows 10, right click on the speaker icon in the right lower corner of the screen, then select "Playback Devices" In the window that opens, right click on the device that represents the soundcard you wish to control and select Properties. On the window that opens, click on the Levels tab and you can see the slider for either Speakers or Line Out - adjust the slider with your mouse. I don't know of any documentation specific to the K3S. For the VOX problem, check the setting you have for VOX delay. 73, Don W3FPR On 12/28/2015 3:03 PM, Bob Novas wrote: > I've managed to hookup my K3S to my Windows 10 box and receive PSK31 using > fldigi, but I'm not having success transmitting.

Do not confuse this unit with the SB-40, which has a dynamic mic, and apparently doesn?t sound so good. The audio out of the headphones is also fine, just as good and loud and distortion-free as the CM-500, at least for communications use. I haven't tried either headset on music.

People on the net said the audio sounded just like the CM-500. I'll give a better long-term comfort report after the RTTY Roundup. The cord is nice and long, and the mic and headphone wires can be separated easily to go to different places, after cutting a little rubber thingie that keeps them together. My mic goes to the back of a computer on the floor, and my headphones go to an SO2R box on the table. The SB45 is around $25 on Amazon, compared to $55 for the CM-500.

It's a matter of personal fit perhaps, but I find the HD280 uncomfortable for long-term contesting use. For casual use for shorter periods of time, I would definitely give them a thumbs up if you need an isolating type headphone, although I prefer the higher priced Beyer DT770M. If you don't need the isolation, I prefer the more comfortable and better sounding circumaural open-back Sennheisers. 73, Barry N1EU On Tue, Dec 29, 2015 at 12:02 AM, AB2E Darrell wrote: > I'll share with the group a very positive experience with an excellent set of headphones I've not seen reviewed for radio before - Sennheiser HD280 Pro, online most places for $99.

One big plus for the HD280s is that you can buy replacement cables for them. I've not seen or worn them, so have no opinion on sound or comfort. Good to hear about the Koss SB45.

The power varies significantly depending upon where I put the TX sensor in the RF chain (K3 -> BPF -> Alpha 87A -> Coax Stubs -> Tuner -> Antenna Coax.) I have a 3" coax jumper on the appropriate end of the P3's TX sensor. I get similar results on both of my radios connecting the TX sensor in the same place in the RF chain. For instance, on 20 meters, with the K3 set to full power and the Alpha 87A in standby, the P3TX Mon displayed power is as follows: TX Mon Location Watts @K3 RF Out 106 -> 6' coax -> @ BPF Input 101 That is a 5 watt measured decrease in a 6' piece of RG-213. @BPF Output 92 That is a 9 watt measured decrease through an Array Solutions W3NQN design BPF. -> 6' coax -> @Alpha 87A RF Out 86 That is a 6 watt measured decrease in a 6' piece of RG-213 and through an Alpha 87A in standby. The Alpha 87A RF Output LEDs show just over 100 watts (the 4th LED flickers.) That indicates to me the TX Mon power displayed is incorrect. When the Alpha 87A shows full output (all green LEDs lit) the TX Mon reads 1329 watts. That is a 13+% difference. I don't have any other power meter as a reference. I have measured both coax jumpers and the BPF individually using an AIM 4170 and a 50 ohm load. The SWR is flat at virtually 1:1 for each. The SWR displayed on the P3 is almost the same when measured at the K3 (1.53:1) and on the AIM 4170 at the end of the coax to the antenna (1.48:1.) Does anyone have a good explanation for this? I know there is a calibration method for the TX Mon, but I that doesn't explain the measured power drop in the RF chain with the amp in standby. 73, Ken, K6LA / VY2TT From kevin.stover at mediacombb.net Mon Dec 28 20:15:01 2015 From: kevin.stover at mediacombb.net (Kevin Stover) Date: Mon, 28 Dec 2015 19:15:01 -0600 Subject: [Elecraft] headphone impedance In-Reply-To: <5681A745.2080206@gmail.com> References: <568177FF.2090900@audiosystemsgroup.com> <56817C90.6010609@audiosystemsgroup.com> <9183F166-FFB5-4BE3-928F-E7C3BC47F56B@frontiernet.net> <5681A745.2080206@gmail.com> Message-ID: <5681DE95.9030109@mediacombb.net> I love my HS-5's.

I don't know if this is a "good" explanation, but it is one that is sometimes [often?] true: Many TX Power sensors actually measure voltage, it's a whole lot easier than power. The meter or display is marked in watts which are computed by the designer from E^2/Z. Z is assumed to be constant, usually 50+j0 ohms. That's rarely the case in reality. Moving the sensor up and down the equipment-coax chain will subject it to slightly different values of Z, ergo E^2/Z changes. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/28/2015 4:50 PM, Ken Widelitz wrote: > I am having an anomaly with the TX Mon power measurements on my P3s.

The "standard" answer is that it is the result of a poor solder connection. I cannot guess at where it could be other than to say due to the periodic nature of the occurrence that it is associated with the MCU in some manner. So check the soldering of the Front Panel board closely. There is only one CPU in the K1, and it is on the Front Panel Board - the firmware on the band board responds only to the band change information from the basic K1. Soldering Tutorial 101: All solder connections should show that the solder has flowed out fully onto the solder pad as well as onto the component lead. If you can see a ring around a component lead, that component has not been heated sufficiently. If your solder connections result in a solder "blob" that is a bad connection (again resulting from insufficient heat to the connection). Solder connections should look like mountains, but not like a volcano. In other words, there should be a small and nice fillet of solder between the solder pad and the component lead. Some builders seem to worry about heating the component leads. The fact is that modern components and boards with thru-plated holes will withstand soldering temperatures for 5 seconds with no damage. Watch the solder. It should flow out onto the solder pad and the component lead in 2 to 3 seconds. If it does not, the iron temperature is too low, and if that happens in less then 2 seconds, the iron is too hot. I have repaired many transceivers where the problem was soldering - usually because the iron temperature was too low or the builder did not dwell long enough on the connection to allow the solder to flow out onto the solder pad and the component lead. Modern components and through-plated boards will sustain a soldering temperature of 800 degF for 5 seconds or longer. I recommend an iron temperature of 750 degF except for the KPA100 and XV transverters which have a large ground plane - for those, 800 degF will work much better. 73, Don W3FPR On 12/28/2015 8:16 PM, Bob wrote: > I just completed assembly of a 30m/20m K1 up through the point of Receiver > calibration.

Good to know this isn't normal, and I will certainly follow your advice and check the front panel assembly carefully, especially the solder. When I initially checked things with an optical loop, the solder appeared to be bright on both sides of the PCB (at least for things I could see). I did use a 700 degree tip on my Weller WTCPT Iron and standard Kester 44 solder, so the potential for decent soldering is there at least. Even though the second CPU on the filter board is mostly inactive, no telling what internal loops are going on that might result in it turning that 4 MHz resonator into a periodic signal. So I'll be sure to check around that too. Of course at this time in the assembly process, the Filter Board is not screwed down. Don't know if that is a source of noise or not. I'm also curious what the AGC_OFF signal is doing on that board. I'll investigate that later. Given that it is appearing in the audio chain (or at least post demodulator), I am suspecting the noise is propagating over the internal power rail. Figures I'd have an interesting problem.

I suspect that you have some incorrect components in the Q7/Q8 base circuit. After checking everything in the Q7/Q8 base circuit, check the PA bias voltage before installing the new Q7/Q8. Do a TUNE and monitor the voltage at the base solder pads for Q7 and Q8, the voltage should be between 0,60 and 0.64 volts. If it is not replace Q11 and Q13 and then recheck. Check all the components in the Q7 and Q8 base circuit for proper values and good soldering. 73, Don W3FPR On 12/28/2015 8:52 PM, K and K Stuber wrote: > While operating my K2 (SN 7581) on CW I heard a loud pop!

All of this is good EXCEPT that N connectors are NOT superior to good quality UHF connectors (Amphenol 83-1SP) for use on the HF bands. Yes, N-connectors are 50 ohm connectors, while UHF connectors are a bit off of that, but it simply does not matter below 50 MHz, and it matters very little below 200 MHz. 73, Jim K9YC 73, Jim K9YC From kk5f at earthlink.net Mon Dec 28 23:46:58 2015 From: kk5f at earthlink.net (Mike Morrow) Date: Mon, 28 Dec 2015 23:46:58 -0500 (EST) Subject: [Elecraft] [K1] Internal Noise Bursts every 12 seconds or so Message-ID: <29847883.1451364419442.JavaMail.root@mswamui-chipeau.atl.sa.earthlink.net> Bob wrote: > Even though the second CPU on the filter board is mostly inactive, no > telling what internal loops are going on that might result in it turning > that 4 MHz resonator into a periodic signal. In addition to the relays on the filter board itself, the PIC on the KFL1 board controls RF board relay K1 (the RF Attenuate ATTN relay). But that info is not likely to help isolate the problem you report. I own K1 #175 that I built in November 2000. It was unfortunately a lightning strike victim a few months ago, ending almost 15 years of service. A most excellent radio for all thoses years. I have never before read a report of a problem similar to what you describe, except for one in 2001 in which a burst of internal noise was generated on 20m after going from transmit to receive. This was caused by the PIC on the KNB1 noise blanker PCB, and1 was corrected by adding a 0.01 uF capacitor on the PIC's Vdd line to ground. It's a long shot, but you may want to check the installation of the similar capacitors on the Display PCB (C4) and KFL1-2 (C27).

You will then get a menu (It's called a Context Menu) that contains, among other things, "Input Devices" and "Output Devices". Click on "Output Devices". You will find displayed a dialog box with all of your output devices. I say "all" because if you're running Windows 10 you're probably running a fairly modern computer and you're likely to have at least three. You will probably have an HDMI output and possibly a Digital Output. Hopefully, you'll have one simply called "Speakers". Highlight the device and then click on the Properties button on the lower left. You'll now have another dialog with some tabs along the top. You should see Audio output as the first item. Lower down you should see controls to adjust your input levels as well. You might have several. Some systems have a "line in" as well as a "mic in". "Line in" is preferable if you have one. The next tab over is "Enhancements". It's wise to be sure that all "Enhancements" are turn off. You can insure this is so by clicking and checking "Disable all sound effects". So - netting it out - Right-click on the speaker icon located on the right side of the task bar. Then choose "Output Devices" and you're all set.

I can say, without a doubt, Windows 10 is the best Windows ever. Windows 7 has pretty much been abandoned with only the most critical security updates being issued. I understand some people don't like the menu system. I don't either and fought as hard as I could to convince the deciders that they were making a mistake - to no avail. They have a long term strategy that they are convinced will win over time. For the here and now, you can greatly improve Windows 10's usability by installing Start 10 . It's costs $4.99 and well worth it. This is advice not an advertisement. With Start 10 installed, your Windows 10 computer will look and work very much like windows 7. There is also Start 8 for people still using the tragedy known as Windows 8. And please, this isn't a Windows 10 problem. Windows has worked pretty much the same way for these devices for the past 20 years. 73, Doug -- K0DXV On 12/28/2015 1:39 PM, Guy Olinger K2AV wrote: > That sounds suspiciously like an entirely Windows 10 issue. > > Click on settings. > > In the "find a setting" box type "volume" without the quotes. > The window will switch to a new label "Search Results". click on "Adjust > system volume" > > You should get a new panel labeled "Volume Mixer". > > Your sound device should be listed.

Those numbers you quote are NOT the output impedance, they are the minimum LOAD impedance that the output device is designed to work into. Modern output stages are essentially constant voltage sources. That's what Bud is telling you with his discussion about damping factor -- the output Z (source Z) is typically 50-100 times the load Z. With headphone amplifiers, a good designer will add some small value of resistance in series with the output to prevent the output stage from failing if a short is connected to its output (which could occur when a plug is being inserted, or with an improperly wired plug). Line level outputs use a series output resistor to prevent the output stage from seeing the CAPACITANCE of a long cable, which could, by interaction with the feedback network, cause the output stage to oscillate. Executive summary -- simply buy good quality headphones, and don't worry about impedance. 73, Jim K9YC From xdavid at cis-broadband.com Tue Dec 29 03:32:06 2015 From: xdavid at cis-broadband.com (David Gilbert) Date: Tue, 29 Dec 2015 01:32:06 -0700 Subject: [Elecraft] K3 - N1MM & keyboard In-Reply-To: <56821D9F.833.1B532EC8@Gary.ka1j.com> References: <56821D9F.833.1B532EC8@Gary.ka1j.com> Message-ID: <56824506.8050000@cis-broadband.com> All you need is a serial port (regular or USB adapter) and a cable to the K3.

But I assume you are using a serial connection to the K3 so that N1MM can read your frequency for logging purposes. If this is true then you probably need to read up on using the memory functions. With 12 slots available you can pre-program some of the memory functions to handle the typical reach-for-the-paddle actions. Such as RRR or ee or 73. You can also press CTRL K to quickly bring up a free form CW/RTTY window that responds to anything you type on the keyboard. You can also program K3 macros into the message slots that access functions on the K3 such as the M1 through M4 memory keys. I always have one macro set up to call up the K3 Auto Spot function. And of course you can change frequency using the mouse wheel which you may already be doing. There is also incredible functionality with respect to skimmer spots. The only additional issue that will need to be addressed is whether you are satisfied with the response you get between your computer and the K3 when sending messages. Sending CW through the serial cable can sometimes come up jumbled. For this and other reasons many people use an external Winkeyer type device to handle the messages from N1MM over a USB cable and then to directly key the K3 through the KEY input jack (not the paddle jack). N1MM is a complicated, feature-rich program. Sometimes it's necessary to take it slow and learn the features during non-contest periods with the K3 in test mode. There are also tutorial video links available on their website. 73, Mike K2MK Gary Smith-2 wrote > When I contest I use N1MM, use the memories on the K3 and send with > the key when needed & I'm busy as a one arm paper hanger doing it > this way.

Yes, there are other dependencies like the weight and "stiffness" of the diaphragm, the strength of the magnet, the coil geometry, etc. However, there is still a strong correlation of efficiency with impedance in well built headphones. 73, ...

I've recently been bitten by the DXing/Contesting bug, and this has led me not only to work very hard on my CW skills (a mode I really, really like but which I'm still a novice at), but to take an interest in exploring the digital modes. I've recently built both the KX3 and PX3 kits with ATU and Roofing Filter, and I'm blown away by the quality of this little radio and its visual sibling. I DO have the cable kit. I'd like to ask for both recommendations on Windows or Mac software to begin working with (fPSK, RTTY and CW at least), and for fairly entry-level step by step instructions (a link is fine) as to how to get the entire mess cabled. Currently, I've got the KX3 and PX3 connected in standard fashion, a Heil Headset/Mic attached to the phones/mic jacks, and one of several keys (K8RA paddles, J-38 key, Begali Camelback, Vibroplex Original Chrome Deluxe) connected to the Key jack. Acc1 from the PX3 is connected via KX3 USB cable to my laptop. I have a Win 7 laptop (which I MAY upgrade to 10, it's an old Core 2 Duo) with headphone in and out and lots of USB ports and an early Mac Pro Tower (1.1 2006 model) running Lion. My understanding is that the stereo cables from my cable set connect KX3 mic in with Laptop Headphones Out, and Laptop Mic in with KX3 headphones out. One thing I wonder is if there is another way to listen to the signal (CW or other) while still seeing the decode/waterfall on the computer. I do have Fldigi and the Free version of HRD. My contesting (logging) software is N3FJP. I have no problems with Rig Control via USB, but I'm having trouble getting connected to any sort of software which supports digital mode or CW deode and getting other than gibberish. I know I'm doing something wrong.....LOL Thanks all, and all help and digital "Elmering" will be appreciated! I did purchase Fred Cady's wonderful KX Line book, which is where I started. 73, Mark From gm3sek at ifwtech.co.uk Tue Dec 29 11:16:39 2015 From: gm3sek at ifwtech.co.uk (Ian White) Date: Tue, 29 Dec 2015 16:16:39 -0000 Subject: [Elecraft] K3 comments on Koss SB45 headsets In-Reply-To: <937E8883FE5F4E79946FBF11F45CCFF1@Toshiba> References: <937E8883FE5F4E79946FBF11F45CCFF1@Toshiba> Message-ID: <00c201d14254$512d62b0$f3882810$@co.uk> Agreed, the SB-45 is excellent. The electret mic seems to be the same as the one used in the Koss CS-100, which has proved to work very well indeed with the K3/S and a number of other rigs. Once the EQ, Compressor and Noise Gate have been set up correctly, the same mic also suits a wide range of voices and attracts favourable comments for both ragchewing and contesting. Beyond that, it's merely a personal choice between styles of headphones. I prefer the closed-cup style of the SB-45 while my wife prefers the lightweight on-ear style of the CS-100; but otherwise they are interchangeable. Definitely recommended. 73 from Ian GM3SEK -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Dave Hachadorian Sent: 28 December 2015 23:40 To: Reflector Elecraft Subject: Re: [Elecraft] K3 comments on Koss SB45 headsets It's quite a coincidence that you asked about the Koss SB-45, because I just got one for Christmas! Mine is the one with 3.5mm connectors, not the USB version. I also have a CM-500. I was going to post a review here after wearing the SB-45 all next weekend in the RTTY Roundup, but here are my first impressions. The microphone quality is fine. The SB-45 needed about 3 dB more boost in TX EQ #4 to sound like the CM-500. The mic is an electret. Do not confuse this unit with the SB-40, which has a dynamic mic, and apparently doesn?t sound so good. The audio out of the headphones is also fine, just as good and loud and distortion-free as the CM-500, at least for communications use. I haven't tried either headset on music. I wore them for 1.5 hours on a long-winded net this morning, and they were totally comfortable over that time period. I do wear eyeglasses. People on the net said the audio sounded just like the CM-500. I'll give a better long-term comfort report after the RTTY Roundup. The cord is nice and long, and the mic and headphone wires can be separated easily to go to different places, after cutting a little rubber thingie that keeps them together. My mic goes to the back of a computer on the floor, and my headphones go to an SO2R box on the table. The SB45 is around $25 on Amazon, compared to $55 for the CM-500. I think this headset is going to be a keeper, but I?ll give a long term comfort report next week.

My view is that you can run an integrated station better on a PC. That is what most of the good software is written for. I use HRD 6 as my basic logging software and N1MM+ for contesting. The difference aren't all that great between what you have and what I run. There may be one exception. N1MM+ integrates with Fldigi as it's FSK interface. I don't know if your contesting software does the same. If it doesn't, switch over. You should feel comfortable with N1MM as it plays quite similarly to W3FJP. I don't use the PX3. I use Win4K3. However, the important thing is that you can see what is happening and react faster than if you had a second receiver, IMHO. I use the KX3 and just love it for contesting. One addition you might want to make is to add a Winkeyer to your collection of stuff. It is an external keyer that can be keyed by your contesting software or just used as your main keyer. In contesting, you set up your macros on the software and just click on a button or hit a function key and your radio starts to send that information. It really cuts down on your fatigue and increases your Qs rate. All of the rest of it is just practice. Get into as many contests as you can. You will make adjustments to your operation as you gain experience, but everyone does. 73, Barry K3NDM ------ Original Message ------ From: "Mark Tosiello" To: Elecraft at mailman.qth.net Sent: 12/29/2015 11:04:09 AM Subject: [Elecraft] Just Starting in Digital Modes >Hi, > >As a ham since 2006, I've been working pretty much straight phone and >hand-keyed (paddled) CW.

Well I can rule out the Filter Board, as the noise is still there when the Filter Board is removed. I hoped I could remove the CPU to see if there was an issue there, but with the CPU gone, the audio is eliminated (probably need to pull something high or low to get the audio back). In looking over the Front Panel Schematic quickly, my attention was drawn to the 6 volt power supply generated on the Front Panel ("6A") and distributed to several high gain parts of the RF board. Any noise on 6A is going to be an issue. I also noted that there is no traditional bulk storage cap on the input of the 78L06 regulator, U4, typically .3 to 10 uF, and while there are a few decoupling caps on the output, the closest one to U4 is several inches away C5. The output cap on a 78L series regulator is typically 0.1uF mounted as close to possible. Finally the original specified regulator has been obsoleted and a different unit was substituted. I've seen issues with TO92 cased 78L series regulators breaking into some strange oscillations when the input or output caps are not sufficient. So I'm going to check that out too. For the moment I will ignore it and move forward to complete the TX section. 73, Bob, WB4SON On Mon, Dec 28, 2015 at 11:46 PM, Mike Morrow wrote: > Bob wrote: > > > Even though the second CPU on the filter board is mostly inactive, no > > telling what internal loops are going on that might result in it turning > > that 4 MHz resonator into a periodic signal. > > In addition to the relays on the filter board itself, the PIC on the KFL1 > board controls RF board relay K1 (the RF Attenuate ATTN relay).

Now you may think this is a rare occurrence; in reality, with any battery, voltage dips occur due to hefty current surges (typically 20 Amps) on SSB. I used/and still use a 110 AHr GMS Deep Cycle battery. The resultant voltage drops were a complete disaster 2) There is a solution which I now use for K3 operation on battery. TE Systems sells voltage boosters which will maintain a constant 13.6 VDC regardless of the transceiver's current draw. However, the battery should be fully charged to start and I use a 75 watt solar panel in parallel with the battery to mitigate current surges during daylight operation. 3) Night operation using the TE device is limited to battery voltage which should not be allow to go below 10.5 VDC else you'll ruin the battery. TE sElls a meter bridge measuring both input (battery) and output (device) voltages for their units to facilitate night time ops. Lots of luck, 73, John Kountz, WO1S/6, T6EE From jim at audiosystemsgroup.com Tue Dec 29 12:55:30 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 29 Dec 2015 09:55:30 -0800 Subject: [Elecraft] Powering a K3s from a battery?

It is well known that IMD (splatter, clicks) with a K3 is least with higher DC supply voltage, and increases as the supply voltage is lower. By 11V, it's increased a lot. IMD is also reduced when the K3 operates at lower power. This is helpful when you're driving a power amp. The KPA500 needs about 25-30W for full power, my big 1.5kW tube amps need about 50W. There is a menu setting for the DC voltage below which the K3 will not transmit. Check the manual. > I have also run from a battery in the shack with a charger connected. No > problem. I currently run from two big 6V golf cart batteries that are float-charged by a regulated DC supply. With the charger connected, I get about 13.4V on TX. Without the charger, the voltage falls below 11.5 V when the batteries are getting low. Because I'm usually driving an amp, I have my K3s set to cut off at 11V. > Clearly the larger the battery, the less problems you will have. Yes, but the battery chemistry also matters. The "normal" operating voltage of LiFePO4 batteries is at least a volt higher than lead-acid, and the discharge curve is flatter. The problem is that LiFePO4 is currently a lot more expensive, and the chemistry requires a special charger. Prices are gradually dropping, and eventually that's likely where I'll end up. 73, Jim K9YC From kk5f at earthlink.net Tue Dec 29 13:21:21 2015 From: kk5f at earthlink.net (Mike Morrow) Date: Tue, 29 Dec 2015 13:21:21 -0500 (EST) Subject: [Elecraft] [K1] Internal Noise Bursts every 12 seconds or so Message-ID: <20615092.1451413282032.JavaMail.root@mswamui-chipeau.atl.sa.earthlink.net> Bob wrote: > In looking over the Front Panel Schematic quickly, my attention was > drawn to the 6 volt power supply generated on the Front Panel ("6A") > and distributed to several high gain parts of the RF board.

I wrote previously: >> It's a long shot, but you may want to check the installation of the >> similar capacitors on the Display PCB (C4) and KFL1-2 (C27). I would look closely on the Front Panel PCB (whicn I erroneously called the Display PCB above) at C4 (0.047 uF) on the 6A line to U1 pin 1 and 11. It of course is on the output of regulator U4. It would be interesting to see what happens to the noise if a similar cap was installed in parallel with C4.

Something I have become more aware of lately is I'll see a faint signal on the monitor and when I when I jump to it with a click using marker A, there is no signal underneath the marker any more. I usually operate CW and the P3 is usually set at a 1-3KHz span. For all the world it looks just like a very weak signal, the kind I look for the most on the air but since it disappears from under the marker when the button is tapped and nothing is heard when looking for a signal, it has to be an artefact. If it remained and was not a station but some RFI, I'd understand but since it disappears, it's got to be an artefact generated in the system.

I'm quite intrigued by what the KX3 can potentially do as an SDR, and am considering trying to get one. There are some downsides to the KX3 I've noted (price and lack of 70cm being two big ones), but the possibilities it opens up are pretty awesome to imagine. I've been playing around quite a bit with packet (AX.25 and APRS over 2m thus far) and am having a hard time figuring out if the KX3 offers advantages over a traditional transceiver's data port. They both /appear/ to require a TNC, although I'm not entirely sure if that's actually the case with the KX3. Is anybody doing 2m AX.25/APRS over their KX3 who could share some details about their setup?

The KX3 is a superb HF + 6M rig; while the 2M transverter does FM, it's real value is for CW, SSB, and digital modes. For FM on VHF/UHF, you're far better off continuing with a standard FM rig for those bands. I like the Kenwood TM-V71A.

It is advertised to connect to a KX3. It looks like it would work good, but for one thing. The baud rate needs to be set to 4800. If there is a KPX100 connected, there is no connection with the amp,since you can not change the baud rate in the amp. My goal is to have a one button tune for my Tarheel when mobile, for safety reasons. I can use the manual button, but then need to put the KX3 in tune, then watch the meter for lowest SWR.

Are you using DATA A mode? If you are using USB mode, you must manually turn off compression and set the equalizer flat. Using DATA A does that automatically. Another thing to consider is that the soundcard output of the laptop may be distorted. You might try an external soundcard. Do you have distortion in SSB voice operation? If no distortion in SSB, there is likely nothing wrong with the K3. Those are the only things I can think of at the moment - unless the problem is with the receiving station. One nice thing about remote operation (if the transmitter is really a good distance from your control position), you can use another receiver and computer to monitor your data mode signals yourself. A modest antenna should do OK for receiving your signal so you may be able to 'sneak it' by the HOA or your building manager. Think stealth antennas for portable work. 73, Don W3FPR On 12/29/2015 4:37 PM, DGB wrote: > I'm using a new K3/0 mini and the remoteRig boxes to remote my K3. > > I'm getting reports of my PSK looking like I'm over driving it. > > I have my laptop soundcard level set down to 10 as recommended by > Brandon.

You will likely have to short the signal path at several points to isolate it. One such point is the input to the product detector - solder a jumper between pins 1 and 2 of T2. If it disappears, you will have to look further toward the antenna - jumper from the base of Q3 to ground (or between pins 3 and 4 of RP6). OTOH, if it is still present with the jumper across T2, the next jumper to install is between pins 2 and 3 of U3 (which should do the same as when the K1 is muted). 73, Don W3FPR On 12/29/2015 12:35 PM, Bob wrote: > Thanks for the ideas, Mike! > > Well I can rule out the Filter Board, as the noise is still there when the > Filter Board is removed. > > I hoped I could remove the CPU to see if there was an issue there, but with > the CPU gone, the audio is eliminated (probably need to pull something high > or low to get the audio back). > > From billamader at gmail.com Tue Dec 29 19:00:01 2015 From: billamader at gmail.com (Bill Mader) Date: Tue, 29 Dec 2015 17:00:01 -0700 Subject: [Elecraft] Powering a K3s from a battery? Message-ID: <000001d14295$086c4a50$1944def0$@gmail.com> Actually, IMD in the PA increases significantly as battery voltage drops! For example, during Field Day a few years ago someone kicked off the generator power to our SSB station which kept operating on the back-up battery. Sometime later the CW captain stopped by asking if we had changed anything. He could hear "splatter" from our 20m signal on his 20m rig. This was not the case earlier in the day. I checked everything and discovered the AC power issue. I turned the outlet switch back to On and checked with the 20m CW operator. His reception had immediately cleaned up! He no longer heard anything from 20 SSB the rest of the (non-contest) event. BTW, we went on to take 4th place overall with just six transmitters (2012). When driving a KPA500, this is much less of an issue since the K3 runs typically under 30 Watts for 500 Watts from the KPA500. NC0B has spoken frequently, in less than glowing terms, about IMD issues in 12 VDC (nominal) PA's. I've seen a number of comments recently that some folks don't care if their radios' TX IMD is high. That attitude is exemplified in many DX pileups. I have raised my power supply's voltage in an effort to keep my TX IMD as low as possible based on my reading and empirical evidence related above. 73, Bill, K8TE Albuquerque DX Assn Message: 23 Date: Tue, 29 Dec 2015 15:57:18 +0000 From: John Macrae To: Marc Veeneman , Juliean Galak Cc: "Elecraft at mailman.qth.net" Subject: Re: [Elecraft] Powering a K3s from a battery?

Notice that he had no indication of the effects of poor IMD due to low power supply voltage. You will *not* hear bad reports from the stations you contact. However, your signal will "splatter" over the band at frequencies away from where you are transmitting. Be kind to your ham 'neighbors' (and they do not have to be in close proximity) and keep that power supply voltage up to reduce the transmit IMD. Most Elecraft products will be happy with a power supply voltage up to 15 volts. I recommend a power supply voltage of 13.8 volts (the voltage of a fully and recently charged "12 volt" lead acid battery). 73, Don W3FPR On 12/29/2015 7:00 PM, Bill Mader wrote: > Actually, IMD in the PA increases significantly as battery voltage drops! > For example, during Field Day a few years ago someone kicked off the > generator power to our SSB station which kept operating on the back-up > battery.

If you are operating in USB mode, I suggest you change to DATA A data submode. That will automatically set compression off and the equalization to flat. You have 2 controls to adjust the audio drive. One is in the computer, set the slider for the soundcard in use to about 2/3 of full scale for starters, and set the MIC SEL to LINE IN - the MIC Gain control in the K3S will allow you to control the gain of the LINE IN signal. BTW, if you are using the internal soundcard in the K3S, make certain you do *not* have anything plugged into the K3S LINE IN jack. If you do, the LINE IN audio from the internal K3S soundcard will be ignored and whatever you have plugged into the LINE IN jack will take precedence. You can adjust the audio levels by placing the K3S into TX TEST mode and no RF will be produced. Once the audio levels are correct, you can adjust the desired power level with the POWER knob. Once the audio levels are set, adjust the VOX gain for reliable transmit. 73 and HNY, Don W3FPR On 12/29/2015 8:12 AM, g0cut1 at virginmedia.com wrote: > Merry new year to all. > I am having trouble operating HRD psk31 to my K3s. > I can set it up to receive via the K3s usb no problem.

You'd be better served by buying an inexpensive 2 meter FM rig. It has everything you should need, and I'm unaware of any APRS activity on 70 cm. There are two meter rigs that already have TNCs built in like the ones that Kenwood sells. Or you can use software TNCs by just using the audio in and out of a sound card.

Something else to note, even at 14V, running a K3 at 11-12 watts is a disaster. Just because you're using "low power" doesn't mean that the amplifier isn't distorting. IMD is also frequency sensitive. One frequency measurements tell you nothing about IMD performance. At 30 watts output on 3.8 MHz my K3 IMD was 17dB lower than at 14 MHz. At 24 MHz the IMD at 10W was 29 dB worse than 30W! In all cases of frequency or output power the IMD was worse at 10W output.

Message-ID: Don kindly helped me out a couple of years ago with my K2 (S/N 3500+) with a PA HOT error when the K2 had been sitting off in my house, room temp about 67degs. Lately now when I turn on K2 from a cold start the fan turns on immediately and when I try to transmit into a 50-ohm dummy load I get the PA HOT error and the rig won't put out power now. Originally, the tPA was set for about 20c which is 68f, which is the room temp in my shack. So, as a hunch I ran tPA through 255 and set it at 5c (41degs f) which, I assume you, is not the temp in my house/shack....HI HI!! I ran tPA back up to 20c and the PA HOT problem returned. So, I set the tPA at 16c (60degs F) and my K2 is now happy! Any thoughts what's going on, is my K2 starting to head South, or maybe I should consider doing a hard reset? I hate a reset cuz all the filters also get reset and even after writing down all the values, it's still a pain in the a**! I have the KPA100 and the latest firmware from a while back.

That is the transistor which senses the temperature. You should re-check the bias setting for the KPA100 after replacing that transistor. The only other possibility is that the TSENSE input to KPA100 MCU has 'gone wonky' and U1 needs to be replaced. 73, Don W3FPR On 12/30/2015 12:24 AM, Eddy Avila wrote: > Don kindly helped me out a couple of years ago with my K2 (S/N 3500+) > with a PA HOT error when the K2 had been sitting off in my house, room > temp about 67degs.

If you have an HPA, then after it's kicked in, (13W in my K3S) the LPA is running at greatly reduced power. I don't believe Elecraft has to change anything. Guys with a KPA3(A) just need to avoid the grey area of 10-15W.

Your experience reaffirms my decision to avoid using a PC at the radio site to serve as an interface to the Elecraft equipment. PCs will at some point hang up or otherwise fail, introducing a single failure point that takes out everything attached to it. Like you I?m using Remote rig for interfacing between the radio at the ham shack in Georgia and my ?home site? in Massachusetts. For my purposes (SSB) this has been a reliable way to stay on-the-air. However, rather than use a PC at the shack to control the KPA500, KAT500, and my rotor (Orion), I?ve taken three approaches: 1. I?m using the Remote Rig RC-1216H to control the KPA500. This provides a web interface to control the amplifier, providing ?front panel? that includes the controls available on KPA-500 front panel including power on/off, standby on/off, amplifier temperature, band selection and including power output and reflected power Led-like display as on the amplifier. It has been 100% reliable and works like a champ. Best of all, it means I can control the amplifier with an Apple Macintosh computer running Mac OS 10.xx, an iPad or an iPhone and not be limited to Windows. BTW, this device also works with Expert Amps, Acom Amps, SteppIR, and certain other rotors, though a RC-1216H is configured for only one of these devices. See: http://www.remoterig.com/wp/?page_id=1010# Ham Radio Outlet now carries these devices after I kept bugging them to offer it last year as they were already carrying the other Remote Rig ?boxes.? I purchased mine in February 2015 and have been very pleased with it. 2. For the KAT-500 I?m using a serial-to-ethernet converter from Lantronix (EDS-4100) that allows me to connect to the KAT500 from a PC where I am. I also use this same serial-to-ethernet device to connect my Orion Rotor as it can handle up to four serial connections independently. Configure the EDS-4100 locally for the serial devices to be connected and install the Lantronix software on the Windows PC and the system thinks it is communicating directly with up to four serial devices (designating four com ports on that PC) when in fact it is over the internet to the radio site. This allows me to run the Elecraft KAT-500 software where I am without being dependent upon a computer at the radio site. I also run PSTRotoAz.exe at the computer where I am to direct my rotor. See: http://www.lantronix.com/products/eds4100/ I purchased mine through Amazon. Note that Lantronix only supports Windows machines. Now, if only Remote Rig came out with an updated RC-1216 to allow a web-based connection to the KAT500? 3. I?m running the West Mountain Radio RigRunner R4005i for internet-based power control to power on/off the Orion Rotor and other accessories. Again, this is a web-based interface allowing me to use Mac OS 10.xx or a windows-based PC to manage the connections. I?ve had mixed results in using an iPad/iPhone probably due to a difference in how these devices interact with web-based interfaces. If I add a login/password to the R4005i configuration, the iPad/iPhone doesn?t deal with it well. See: http://www.westmountainradio.com/product_info.php?products_id=rr_4005i In addition, I also have a USB-to-Ethernet device (Digi International?s AnywhereUSB) that allows me to run the Wave Node WN-2 and certain other USB devices remotely. I initially purchased this to use with my Flex-5000 and Alpha amplifier. It works well and allows me to monitor power output and SWR as measured externally as provided by the WN-2. It did not do well with controlling the Alpha amplifier using the software available from RKR Designs (v1.4). I suspect that the timing delays going over the internet causes problems, but it did work well connected to a PC in the shack. I have not tried controlling the Alpha through the Lantronix serial-to-ethernet device; I will do that at some point when I?m back at the radio site. I will also point out that AnyWhereUSB does not deal with Audio USB well; for example, it doesn?t deal with Fun Cube Dongles at all. Likewise, as with the Lantonix device, the AnywhereUSB only works under Windows (not Mac OS). See: http://www.digi.com/products/usb-and-serial-connectivity/usb-over-ip-hubs/anywhereusb The key to making this all work is the ability to connect to the radio site?s LAN and be able to ?see? the IP devices (Serial-to-ethernet, USB-to-Ethernet and Remote Rig). This can done a variety of ways including VPN or via DDNS and Port Forwarding. In my case, I had a commercial firm configure two Sonic Wall routers for me (one for each location) where essentially one LAN can interact with the other well enough where the web-based devices (RC-1216H and RigRunner), Serial-based devices (Lantronics), and AnywhereUSB in Georgia are recognized by the computer in Massachusetts without having to resort to VPN. It essentially provides a seamless process for controlling my amateur radio HF station without having to resort to a PC at the radio site. It also removes to some degree a ?single point failure?. For example, if the RC-1215H were to fail, I could still turn on and operate my rotor along with the K3 and KAT500 sans amplifier. I suspect that over time there will be more web-based interfaces developed for a variety of amateur radio applications, thus avoiding the need for PC at the shack to allow remote connection. In the meantime, I?m pleased with how my shack has evolved to allow improved remote operation. 73 & Happy New Year, Barry Baines, WD4ASW Westborough, MA > > 73 and a HNY Jeff kb2m From k6mr at outlook.com Wed Dec 30 12:10:19 2015 From: k6mr at outlook.com (Ken K6MR) Date: Wed, 30 Dec 2015 09:10:19 -0800 Subject: [Elecraft] Remote KAT500 Message-ID: A couple of possibilities: Use a USB/Serial converter at the tuner end and employ a USB over CAT5 extender device/cable to get there. CAT5 cable is cheap. There are also RS422/RS232 converters out there. RS422 is good for about 4000 feet as I remember and the converters are not very expensive. More expensive but more flexible is a run of duplex fiber optic cable with fiber/Ethernet converters on each end. I use this method and run the fiber in the same conduit as the coaxes between the radios and the tuners/amps. Fiber of course ensures no radiated noise. Plus if you want to control something else at the far end it?s easy to expand.

By the C revision, this was replaced by cable capacitance that the driver could feed. In practice RS-232 can regularly drive several hundred feet of cable, depending on the data rate. The problem in all this is the driver in use. If the driver meets the EI-232 spec, then there should be no problem. However, equipment that takes shortcuts (0-5V swings for example) are probably meant to just connect to something next to it. Thus the real answer is, ?try it.? If communications is flakey you may need to lower the data rate, but most likely you will be able to find a setting that works. Let us know what you find! - Jack, W6FB > On Dec 30, 2015, at 11:57 AM, Cliff Frescura wrote: > > 8 ft is not true for rs-232.

Beyond 100' I would expect that the bit rate would have to come down too, but I haven't tested that. I would also suggest a full 9 wire PLUS shield cable, bonding the shield at both ends to the device/computer chassis via the connector housing. You may need some ferrite too, to be determined.

I have made already some qso's at 100 watts. but .. when I was using the KX3 barefoot, it was connected to my PC via the KXUSB cable at ACC1, which provides an RS232 to USB conversion ; and logger32, which is my logbook software, was reading the KX3 frequency on the simulated COM6 port. I was expecting that the same will occur when I use the same hardware connected this time to the RS232 exit on the KXPA100 ; but now logger32 doesn't receive the frequency info from the KXPA100 when the PA mode is selected. When the PA mode is OFF , logger32 reads the correct frequency If I come back to the KX3 barefoot configuration, logger32 receives the frequency data as before. What did I missed ? I suppose something is not behaving as I was expecting on the RS232 exit from the KXPA100 when he is ON ? Thanks for any help !

The CODEC used in the KIO3B is from the same family as used by most of the amateur USB sound card products (including microHAM USB Interface III). Unless the designer cuts corners (like the designer of the Signalink USB) by eliminating critical power supply bypassing and regulators, performance of all devices using the same family of USB Audio CODECS will be very similar based on the limits of the 16 bit ADC, the noise figure of any audio preamplifiers used by the designer and the power supply noise rejection (does the design properly keep digital noise out of the power supply for the analog circuits?). I have not tested the KIO3B but I certainly would not expect that Wayne cut any corners in the design. Thus performance of the KIO3B and microHAM USB Interface III (noise floor, dynamic range, etc.) should be nearly identical - within unit to unit manufacturing tolerances. 73, ...

The other limiting factor is the capacitance between conductors in the cable - that distorts the waveform. It might work if you invest in good quality cable and work with slower baud rates. I would think the loss through 150 feet of LMR400 would be low enough to be practical and allow the KPA500 to live in the shack. 73, Don W3FPR On 12/30/2015 9:47 AM, Va3ied wrote: > My tower and garden shed are about 150 feet away.

Does that also apply to the KX3 which is also a 10-12w radio (160-24m)? I'm finding that hard to swallow considering the QRP background of the Elecraft owners. I note the topic started about using a battery but you cite this is still true at 14v regulated supply. Or are you saying this only about running the HPA at 10w? (which I do not have). I thought the HPA switched off below a set power level (again, not something I need to know since I do not have a HPA). Wayne you want to respond on this? I'd like to think I did blow a whole lot a money on a defective design (I bought both the K3/10 and KX3).

All I'm saying is that if you run the LPA at 10-12 watts, according to my measurements*, the IMD is pretty bad. If you have an HPA, then after it's kicked in, (13W in my K3S) the LPA is running at greatly reduced power. I don't believe Elecraft has to change anything. Guys with a KPA3(A) just need to avoid the grey area of 10-15W.

In the late 90's, my employer had a contract with Wells Fargo Bank to help plan and execute the move of a major data center from San Francisco to Roseville CA. As you might suspect, we became close friends with the WF IT folk. It so happened that my employer had recently purchased Network Solutions Inc., then the sole Internet domain registrar. At that point, they were updating the DNS network daily. While in a WF facility in PHX, I began to get what looked like random numbers on my pager [remember those?] On the premise that someone REALLY wanted to contact me, I began putting parts of the numbers into my Palm Pilot Zero [remember those?]. Mike [WF IT guy in SF] popped up, I called and asked if he was trying to reach me. In a huge panic, he said, "wellsfargo.com had disappeared from the Internet. Can you call NS since you own them and get it fixed." I did, they fixed it but it took about 12 hours to propagate everywhere. We tend to take things like the telephone and Internet for granted these days, actually we did then too. They do occasionally have hiccups. For the record, the Elecraft site comes up fine in NW Nevada. 73, Fred K6DGW Sparks NV Washoe County DM09dn On 12/30/2015 3:06 PM, Lynn W.

I don't think that was what was suggested at all. I read the post to be an observation of a *relative* condition. All amplifiers [at least that I've ever encountered] exhibit increasing distortion near their rated power limits. I've always assumed that's why distortion numbers are almost always accompanied by the power when the measurements were taken. My K3/100 is a K3/10 below about 15 watts ... the 100 W amplifier switches out of the circuit. I think all that the post was trying to point out is that, from 100 W downward, the distortion will decrease *until* the KPA3 cuts out. At that point, the LP amplifier/exciter is near it's max power, and it's distortion will probably be higher than the values from the KPA3 operating just above that power. In any case, absolute distortion from a K3/ is still among the lowest in the marketplace. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/30/2015 2:13 PM, Edward R Cole wrote: > Wes, > > So you are saying all of us with K3/10 should never run at 10w+ because > the LPA is a terrible producer of IMD?

I suggest a different solution for the wiring. Use a decent grade of CAT5/6 cable, using one pair per circuit. CAT5/6 is four twisted pairs, which inherently reject noise, and it has low capacitance between conductors. To avoid Pin One Problems, tie all four "striped" conductors together and wire them both to the signal ground pin and to the connector shell on both ends. If you do use shielded CAT5/6, wire the shields to the connector shells and the four striped conductors to the ground pin. Years ago, we used RS232 to control sophisticated audio signal processing systems in theaters, stadiums, and churches. The RS232 cable was often 200 ft or longer, running to a laptop. These links worked fine. I don't recall what baud rates we used. As to bandwidth -- RS232 is an un-matched protocol, with a low-Z source and high Z receiver, so bandwidth/baud rate is limited by cable capacitance. That's why the spec was revised many years ago to reflect the availability of low capacitance cables. 73, Jim K9YC From w3fpr at embarqmail.com Wed Dec 30 19:36:28 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Wed, 30 Dec 2015 19:36:28 -0500 Subject: [Elecraft] Elecraft gear relative IMD In-Reply-To: <56846E49.9010905@foothill.net> References: <201512302213.tBUMDmQ9011086@mail40c28.carrierzone.com> <56846E49.9010905@foothill.net> Message-ID: <5684788C.9030806@embarqmail.com> I think it is time to change the subject line (and I did). The original question was about increased IMD with lower power supply voltages. It has now morphed into the relative IMD at different power levels with higher (normal) power supply voltages. Whatever the actual IMD of the K3/K3S at any power level, the information I have heard from contesters and DXers is that the Elecraft gear is has lower IMD than most other transceivers. We have heard testimony to that repeatedly from Field Day setups and DXpeditions where there are multiple transceivers operating in close proximity to other stations. When station A cannot hear anything interfering when station B transmits, that is a good thing. Elecraft gear can do that while many other manufacturer's transceivers cannot say the same thing. What we do know is that higher power supply voltages provide better IMD figures, and since the Elecraft gear is rated for up to 15 volts, we will achieve better IMD performance if the power supply is cranked up to provide a voltage just a bit below 15 volts. 73, Don W3FPR On 12/30/2015 6:52 PM, Fred Jensen wrote: > Ummm ...

What is the choking impedance of that common mode choke? Take a look at the writings of Jim Brown K9YC for effective common mode chokes. The fact that you do not have the problem with the MH3 microphone strongly suggests that there is not a problem with the KX3 or KXPA100. Both microphones you mentioned are dynamic type and should have Bias turned off. You might check the coax connections and your coax jumpers. PL-259 connectors should be fully seated and be given just a bit more tightening than "finger tight" to make an effective connection to the coax shield. Use pliers to snug them up a bit after making them finger tight. Try different coax jumpers - it is not uncommon to have the connection to the shield fail. 73, Don W3FPR On 12/30/2015 7:31 PM, Jim Kutsch, KY2D wrote: > I'm running a KX3 and KXPA100 here.

Hi Scott, We have attached, below, the procedure to train and optimize the KAT with the KPA500. After the training is completed, please leave the KAT in the MAN position. It should operate better for you in that position. We would suggest you have the latest firmware loaded into the KAT. You can place each antenna on its own port and train the KAT for those bands. Once trained, the KAT will find the closest full cycle tune for the frequency you have landed on. If it can not find a successful tune, you will need to tune the KAT while in the MAN position to get the VSWR down at that frequency. As a side note, the use of the KAT Utility can provide the actual Bypass VSWR (under the Operate tab). This is what the KAT is actually seeing throught the transmission line. The Bypass VSWR should not be above 10 to 1, or the KAT will not be able to complete a full cycle tune. We hope this helps. 73, -- -------------------------- Craig Smith W6WL Elecraft Customer Support831-763-4211 x 174 -------------------------- ****************** Here is a procedure to setup your KAT500 with a KPA500 *********************************** Please enter the KAT500 Utility and select the Configuration tab then click on the button to Optimize for KPA500. *Training the Tuner* *Overview* We will be stepping through each band where you have an antenna connected to the KAT500, selecting the top, bottom and places in the middle of each band where you expect to operate. At each of these points, we will be causing the transceiver to emit a steady-state, CW RF signal for the KAT500 to use while it executes a full tune cycle. Since the KAT500 is an Automatic Tuner, it will remember the settings it finds at each of the points in the band. This is referred to as 'Training the Tuner'. The following sequence assumes that the transceiver, KAT500 and, if appropriate, the KPA500 are installed as specified in the KAT500 Owner's Manual, Figure 4. *Set up* - On the transceiver set it up to generate 25 watts. We recommend that you set up a way to generate 25 watts of RF with a constant carrier wave (CW) that can be keyed at will. This CW signal at 25 watts will need to be present until the KAT500 has completed a full tune cycle. - On the KAT500, select the MAN mode. - On the KAT500, Tap the ANT button to select the appropriate antenna for the selected band. The ANT LED will light solidly indicating the antenna port selected. - On the transceiver, select the the appropriate band. Then, adjust VFO to the lowest spot in that band where your antenna will work. *For each VFO Setting perform the following to Train the KAT500*: 1) Then, Tap the MODE button so that AUTO is enabled. The AUTO LED will stay on solidly. This places the tuner into Automatic mode so that it will remember the settings found during the upcoming tune cycle. - Next, Tap the TUNE button on the KPA500. The AUTO LED will now start to Flash. This indicates that the KAT500 is now awaiting the RF needed to execute a full tune cycle. 2) Cause the transceiver to send its 25 watts of CW RF 3) The KAT500 will begin to clatter as it searches for a low SWR. This is the Full Tune Cycle. The clattering will stop once a low SWR is found and the KAT500 AUTO LED will now be solid. This indicates that the full tune cycle is complete and the results have been memorized. - On the transceiver, adjust VFO frequency for the upper end of the band where your antenna will operate. Repeat Steps 1-3 above for this setting. - Then, move into the middle of the band and repeat Steps 1-3 again. *Train the tuner on all Bands* - Next, step to other bands where your antenna can operate within a 10:1 SWR ratio. Perform the same steps above as with the first band chosen. - How do you know how many times per band needed to fully train the tuner? Here's the answer from the KAT500 Owner's Manual. *Training the tuner with all of your antennas* If you have more than one antenna, continue to ANT 2 and ANT 3 ports using the same technique above for those antennas. The KAT500 tuner can remember settings for all 3 antenna ports separately! *Make it easy for your Tuner to remember what it was trained to do* Once you have fully trained your KAT500 tuner on all bands and all Antennas, you can save your work using the KAT500 Utility. Go to the Configuration tab in the Utility and select Save Configuration to complete your tuner's training.

I suspect it's a wiring problem. The RE15 is a dynamic pro mic and is balanced; pin 1 is the shield, Pins 2 and 3 are the signal pair. To connect any balanced dynamic mic to an unbalanced input (virtually all ham rigs) connect either side of the pair to the shield and to the sleeve of the Elecraft mic connector, connect the other side of the pair to the "high" side of the Elecraft mic connector. It's easy to make an adapter cable. Start with a female XLR3 connector and a male plug that mates with the KX3. A piece of RG58 or miniature coax like RG-174 work fine as a mic cable.

When I work in a pileup, I narrow the span to just cover the pileup (and DX). After I finish, I use a fn button to return to my normal span. The P3 keeps the same center frequency and widens the span, regardless if the new span includes frequencies outside the amateur band I'm working. As I almost never want to see what is happening outside the amateur bands, it would be nice if switching to a wider span would keep the entire span within the current band. For example, I am trying to work a DX and end up with a center of 14.021 and a span of 8KHz. When I finish and press the "Span 100" fn key, I end up with a frequency range of 13.973 to 14.073, when I would like 14.000 to 14.100. My suggestions are: For switching to a new band: Keep the old span and center. For setting span with the knob: Do not extend the top or bottom outside the band until the span exceeds the width of the band. For setting span with a fn key: Do not extend the top or botton outside the band unless the span is wider than the band. For setting the center: Allow the span to extend outside the band. These suggestions would help a lot with 17M and 12M, where the band edges aren't on 100KHz boundaries. 73 & HNY Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)356-8506 | services.

I did the transmitter gain calibration using the Elecraft K3 Utility. This week, to satisfy my need for rosin fumes, I completed a W1. I carefully calibrated the W1 using the DMM method (Fluke 189). Working into a 50 ohm dummy load, I notice that the W1 reads considerably higher power than that set on the K3s. The W1 is generally about "one LED" higher than the K3. For example, right now when the K3 setting just reaches 79 watts, the W1 100 watt LED illuminates. Before digging deeper, is there a known answer to the question "Which one is correct?"

This conversation had already given me the idea that I should remeasure the two radios' IMD at different voltages, as well as vs power vs. frequency. But you are asking for two different things, IMD and spurious signals. With a nominal "12 V" radio, absent some fancy feedback, IMD products will never be down 50 dB in this lifetime, even when using the "cheating" (IMHO) dB-relative-to-PEP method. Looking for and measuring spurs, other than harmonics, is a job for a spectrum analyzer, something I lack.

I have calibrated the K3s using Elecraft K3 Utility 2. I have carefully calibrated the W1 using the DDM method with a good quality DDM. 3. Comparing the results, I see that the W1 consistently calculates power about 1 dB higher than the K3s. Statistically, I would have expected them to be closer. From the W1 specifications, and not knowing the K3s power accuracy specifications, it seems that, possibly, the K3s is displaying about 3 sigma low and the W1 3 sigma high, which is unlikely. 4. The question: Should the K3s be calibrated from the W1 or should the W1 be calibrated from the K3s? (There could be a detailed, separate discussion of the meaning of "average" power and "PEP" as used in the W1 programming reference. It is my belief that the two should be the same thing if using a cw signal and the FCC definition of "PEP". It would be interesting to know what is going on in the K3s transmitter gain calibration process. It seems like there is an internal power measurement process and the gain is being set against that. Does that internal measurement process have accuracy equivalent to the W1 or vice versa?)

Do you have the KAT internal antenna tuner? If there is an SWR on the antenna line that the KAT is tuning out for the transceiver, then the W1 will read forward power and reverse power on the antenna line whereas the K3 will read output power. If you subtract the W1's reverse power reading from the W1's forward power reading, does that compare to the K3's power reading? Try reading the two power meters into a good dummy load. Then the K3 reading and the W1 forward reading should be equal.

The ProSet-K2/K3 uses an electret element which has a high output level - it needs to have bias turned on.

The IC version of the Heil was, as I understand it, introduced as a suggested model for Icom radios (thus the "IC" designation), and has an electret cartridge. Electrets apparently work quite well with Icom gear, and they work very well with Elecraft gear. As most already probably know, many of us who have Elecraft K3's and K2's have opted for the Yamaha CM500, which also has an electret cartridge, and is considerably cheaper than Heil's models. All the bias requirements for electrets are handled through menu options on the K3, so it is very simple to use them. It also plugs directly into the back of the K3, so you don't need any of the adapters. The K2 will also provide the necessary bias, but you have to change a connection internally. I personally don't find any particular benefit to either the Heil or the Elecraft models, and I have both. The Yamaha works great.

My original K3s test setup was per the manual: good quality dummy load (not the DL1 because of its 20 watt upper limit) with the ATU off. My high quality dummy load does not have a test point. After reading your results, I decided to take the DL1 as my "truth model". I found that the W1 display was 0.8 dB high and the K3s power display was 0.9 dB low. Each one was at the opposite end of the error budget. (sort of like winning the "losers" lottery). So, I set up the W1 to match the DL1 up to 20 watts and, surprise, the W1 TP voltage is now 4.87 volts. I don't have the W1 software and cabling installed yet. At that time I can fine tune all of this. It seems as though a consensus is building that the W1 manual specification of 4.5 volts is no longer correct, unless there is something "off" with the W1 internal algorithm. Good stuff. Thank you everyone for your comments and help. -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of John Oppenheimer Sent: Thursday, December 31, 2015 7:22 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] W1 Hi Ed.

The regulation states (I'm paraphrasing from memory) that the bandwidth of the transmitted signal shall be no greater than required for the means of transmission. I've served on the AES Standard Committee, and that's the sort of language used to say that the signal should be as narrow as possible, but that it is understood that through the years, it will be possible to make narrower rigs, so it leaves out the number, which is a moving target. Elecraft has pretty well set the standard for the bandwidth of a CW signal, thanks to the careful control of the keying waveform, pretty low IMD, and a design architecture that produces very low phase noise. In my tests, I see the K3 as no cleaner than other rigs I've tested on SSB, but significantly cleaner on CW, RTTY, and digital modes. Important note: IMD strongly affects the bandwidth of a CW signal, because CW is 100% amplitude modulation of a carrier by a square wave. Square waves have an infinite number of harmonics, the strength of which are related to the rise time of the CW keying (and NOT to CW SPEED). The IMD of a gain stage that amplifies that signal WILL produce sidebands (clicks). CW keying bandwidth can easily be measured using a spectrum analyzer that has low enough resolution bandwidth. A P3 can do it, and a P3 with SVGA has even lower resolution bandwidth. Likewise, an SDR with suitable software can do it, and I'm planning to buy an ANAN 10E for measurement only. But the FCC Rules make the operator responsible for occupying the minimum spectrum. So that means buying a rig that's clean in the first place, giving the rig enough DC voltage, and not overdriving audio stages and power amps. 73, Jim K9YC From w4rm at aol.com Thu Dec 31 13:09:59 2015 From: w4rm at aol.com (Bill OMara) Date: Thu, 31 Dec 2015 13:09:59 -0500 Subject: [Elecraft] Elecraft web site In-Reply-To: References: Message-ID: <031c01d143f6$7633ff30$629bfd90$@aol.com> I'm also having a problem getting to Elecraft Web page.

After they download, you should see the information in the "Firmware Revisions" section. You should see the list of what is installed in your K3S as well as what is Available. If your firmware is at a lower level that what is available, you can click either the "Send All Firmware to K3" button or the "Send All New Firmware to K3" button. The firmware load should proceed automatically. Yes, if you cannot connect to the Elecraft website, you will not be able to get the firmware files into your computer. Click on the Configuration tab and see if you can save your current configuration. 73, Don W3FPR On 12/31/2015 1:21 PM, John K3TN via Elecraft wrote: > New K3S arrived, seems to work fine as a radio > Came set for CONFIG:USB, connect Elecraft USB cable to Win 7 laptop, all drivers seemed to down load OK. > But when I start up K3 Utility, I get a COM Port 5 connection but will only say "K3 waiting for firmware load: RS232 speed 38400 bit/s" > This is version 1.13.5.9 of the K3 Utility, thought maybe needed later version - but Elecraft.com seems to be down.

In the one with the low end, I agree, no 60 Hz, 120 Hz or 180 Hz is seen. I measured my K3S with the radio connected to the computer via the USB port. No 60 Hz, 120 Hz or 180 Hz signal observed. I suspect if anyone is experiencing "hum" they best look for a ground loop which likely exists as there is a difference in potential between different pieces of equipment. 73 Bob, K4TAX On 12/31/2015 1:15 PM, ab2tc wrote: > Hi again, > > BTW, some people have been complaining about 60Hz hum in the audio.

Seriously. We need to think about two questions: Who owns the internet? How is it managed? The answers: nobody owns the internet. It's a network of networks ("Internet" is a contraction of inter-network, the protocol to tie multiple networks together). The various network owners manage their own networks. The really large networks can be called "backbones" but even that term is somewhat meaningless. The "management" is essentially chaotic. Nobody is driving the bus, but people make sure that all of the bus parts end up at the next stop. From here (on Verizon's dismal rural DSL) there are five networks on the way to Elecraft. Any one of them can have a bad day and I'd have trouble reaching www.Elecraft.com. The one thing I'm certain of is that all of us follow different paths through different networks, and any of those intermediate sites can have trouble. The odds are that it's not your provider, and it's not their provider, it's someone in-between, and generally speaking, they won't take complaints from you because you don't pay them. They'll fix it sooner or later, because someone who does pay them will be having issues. The amazing thing is that most of the time the internet is incredibly reliable. It's mostly self-healing. Mostly. Kinda. It's fun to talk about. 73 -- Lynn On 12/31/2015 11:22 AM, Robert Dorchuck wrote: > I am still unable to connect to the Elecraft website.

When checking shipboard radio installations in preparation for their annual FCC inspections, I used a variety of different specs the gear had to meet based on its year of manufacture. Older gear had a lot looser specs than the newer stuff. The same is true for Ham rigs. It's perfectly okay to run an old Heathkit AT-1 or a 1930's homebrew rig with cathode keying today as it was back then, even though the keying bandwidth will be substantially greater than modern rigs. The bottom line is to make sure the rig you have is being operated to produce the cleanest signal its design allows in the mode of operation being used. That's why double-sideband amplitude modulation is still legal even though it requires more than twice the spectrum of an SSB signal and CW is still allowed even though SSB and the various digital modes provide the same information in yet smaller bandwidths. 73, Ron AC7AC From jim at audiosystemsgroup.com Thu Dec 31 18:10:11 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Thu, 31 Dec 2015 15:10:11 -0800 Subject: [Elecraft] KIO3B Audio Spec In-Reply-To: References: <7F199BDA01F3454FAF5FAEE93DD4D1C8@ejhPC> <5675AB06.5000903@necg.de> <00ed01d13aa8$5d1f1590$175d40b0$@erols.com> <5675D960.8030704@necg.de> <5675E227.6060001@horizon.co.fk> <5675F6FD.6010407@gmail.com> <1451509529893-7612028.post@n2.nabble.com> <56844DB7.2000009@subich.com> <1451588737200-7612091.post@n2.nabble.com> <1451589343843-7612094.post@n2.nabble.com> Message-ID: <5685B5D3.9050106@audiosystemsgroup.com> On Thu,12/31/2015 11:29 AM, Barry N1EU wrote: > You'll get hum if your computer and K3 chassis aren't at the same ground potential.

WRONG. Double-sideband AM with a carrier is legal because it is a DIFFERENT mode permitted by the FCC Rules. (A3 is the FCC designator). SSB is J3 if the carrier is suppressed.

Right now, New Year's eve, there is an on air event taking place, Straight Key Night, that encourages the use of antique rigs on the air and is sponsored by the largest association of Radio Amateurs in the USA, the ARRL. Amateur radio is still a homebrewer's hobby, encouraging Hams to design, build and maintain their own rigs frequently without access to modern equipment to evaluate their performance. I believe it is for that reason the rules are very loose about things like spectrum bandwidth. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Thursday, December 31, 2015 3:27 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Elecraft gear relative IMD On Thu,12/31/2015 3:07 PM, Ron D'Eau Claire wrote: > The same is true for Ham rigs.

CW is A1. 73, Jim K9YC From w3fpr at embarqmail.com Thu Dec 31 19:32:36 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 31 Dec 2015 19:32:36 -0500 Subject: [Elecraft] KIO3B Audio Spec In-Reply-To: <5685BBEF.7080403@blomand.net> References: <7F199BDA01F3454FAF5FAEE93DD4D1C8@ejhPC> <5675AB06.5000903@necg.de> <00ed01d13aa8$5d1f1590$175d40b0$@erols.com> <5675D960.8030704@necg.de> <5675E227.6060001@horizon.co.fk> <5675F6FD.6010407@gmail.com> <1451509529893-7612028.post@n2.nabble.com> <56844DB7.2000009@subich.com> <1451588737200-7612091.post@n2.nabble.com> <1451589343843-7612094.post@n2.nabble.com> <5685B5D3.9050106@audiosystemsgroup.com> <5685BBEF.7080403@blomand.net> Message-ID: <5685C924.4020504@embarqmail.com> Bob and all, Bonding to a common point may not cure hum and buzz. Follow the advice of Jim Brown K9YC and bond from equipment to equipment - following the path of the shields on unbalanced audio cables and RF coax. In other words, bond from the computer to the K3 (or from the computer to any interface box, and then the interface box to the K3). The K3 to amplifier if present, then to the tuner if present. The bonding wires will take the majority of the current that *might* otherwise flow on the shield of those cables and reduce the possibility of noise coupling into the signals. Whether you also bond to a common point in the station is an entirely different matter. That common point ground may do well for AC safety and possible a measure of lightning protection, it will do nothing for the coupling of hum and buzz onto the signal paths. Jim often talks about the "pin 1 problem" which is part of the situation, but providing an extra low impedance path direct from equipment to equipment will do more to keep all pieces of your equipment at the same relative potential than any other means. 73, Don W3FPR On 12/31/2015 6:36 PM, Bob McGraw - K4TAX wrote: > Yes, this is correct. > > I have all of my station equipment bonded to the common point on the > station power supply.

Bonding from equipment to equipment is a series circuit in which the voltage divides across each value of R. Thus none of the equipment will be at zero potential. By using a bond conductor from each piece of equipment to a common point, this provides a star system which is endorsed by most audio and system design specialists. It provides the lowest resistance as all conductive paths are parallel. 73 Bob, K4TAX On 12/31/2015 6:32 PM, Don Wilhelm wrote: > Bonding to a common point may not cure hum and buzz. > Follow the advice of Jim Brown K9YC and bond from equipment to > equipment - following the path of the shields on unbalanced audio > cables and RF coax.

If you want to hear how bad some of those antique transmitters were, do listen tonight for SKN. Bad chirps, bad keyclicks and lots of phase noise that spread the signals out over a large portion of the band. The bands today are more crowded than they were back then, and while it is legal to use those antique transmitters and receivers, I do not think it should be an everyday event. Yes, I know several hams who are into 'boat anchors', particularly those old AM transmitters. Fortunately, that crowd concentrates on 80 meters when the band is not full of signals, but listening with today's more selective receivers and hearing signals in a 'net' so spread out and off frequency, it amazes me that we were able to communicate easily back then. BUT we did, and had fun doing it. I would not advocate using those transmitters and receivers in a contest today, but they did work for us back then. BTW, I was first licensed in 1955, so you can perhaps understand the advances in technology that I have seen over the years. There has been a LOT. I have often considered building again my Novice transmitter which I assembled from the article in the 1955 ARRL handbook (a 6CL6 xtal oscillator and a 6146 final), but obtaining the parts is almost impossible. Can you find 1 1/4 inch diameter, 4 pin coil forms these days? Maybe, but they are prohibitively expensive, and the power transformer is almost impossible to find although back then, they were quite common because they were used in TV designs. I pass by the flea market areas at hamfests and get enough of my nostalgia satisfied by looking at those old transmitters and receivers that I drooled over 'way back then' knowing that as a teen with limited income I could never afford them. I don't have time nor energy to restore any of those 70 pound radios, nor does my hamshack have space for them, so I look and marvel, but do not take any of them home with me. I do have my homebrew receiver, a version of the HBR-16 and an old NC100 receiver that I may someday bring out of the attic and bring back to operational status, but that is pretty far down on the priority list for me. Enjoy SKN and listen to those old transmitters (and even listen on your vintage receiver). It is a telling story of the history of ham radio and the gear available in the years gone by.

The important point is that adjacent pieces of equipment be at the *same* potential, whether that be at zero or 100 volts potential. OK, that is an extreme example, but the point is that there should be a low resistance connection between devices sharing an unbalanced connection between the two, and that low resistance connection should be something other than the shield of the audio or RF unbalanced cables. The easiest way to accomplish that condition is to bond the equipment from point to point by good heavy wire or braid. Since we commonly use computers in our ham stations, that is one source of hum, buzz and other noise. Bonding the computer straight to the transceiver will cure many ills. We did not have those problem in older gear where the connectors were mounted to the enclosure of the equipment, but modern construction where the input and output jacks are mounted to the PC board causes stray hum, buzz and noise and RF currents to be coupled to the PC board rather than being routed to the outside of the equipment enclosure is one of the primary causes of the problem - that is the "pin 1 problem" that Jim Brown K9YC refers to. 73, Don W3FPR On 12/31/2015 7:44 PM, Bob McGraw - K4TAX wrote: > Don et al: > > Well Jim and I are at 100% opposite positions on this point. > > Bonding from equipment to equipment is a series circuit in which the > voltage divides across each value of R.

I'll operate my DX-40, or Viking II, or 100V or other vintage rig anytime and anywhere I please, thank you. These radios don't generally chirp wildly or have substantial phase noise. If phase noise is a concern, be concerned about some of the infamous 80's import all mode solid state, with a hundred tiny knobs, impressive looking expensive radios that could well clear out a band. Fortunately that junk doesn't show up very often. A well built tube transmitter, vintage or not, is a good thing. A modern receiver is a great tool and we wail when it's S-meter reading is off by .01dB or it drifts 2 HZ or there's something wrong with a Windows driver or whatever. A vintage one with a pair of 6V6s driving a large loudspeaker and an operating manual that doesn't require a search engine has character, soul, and audio that has to be heard to be believed, even if it can't read freq out to a few milli-hertz :) And other than contest weekends, I keep searching and searching for crowded bands ...

Fortunately, that crowd concentrates on 80 meters when the band is not full of signals, but listening with today's more selective receivers and hearing signals in a 'net' so spread out and off frequency, it amazes me that we were able to communicate easily back then. BUT we did, and had fun doing it. > > I would not advocate using those transmitters and receivers in a contest today, but they did work for us back then.

Can you find 1 1/4 inch diameter, 4 pin coil forms these days? Maybe, but they are prohibitively expensive, and the power transformer is almost impossible to find although back then, they were quite common because they were used in TV designs. > > I pass by the flea market areas at hamfests and get enough of my nostalgia satisfied by looking at those old transmitters and receivers that I drooled over 'way back then' knowing that as a teen with limited income I could never afford them. I don't have time nor energy to restore any of those 70 pound radios, nor does my hamshack have space for them, so I look and marvel, but do not take any of them home with me. > > I do have my homebrew receiver, a version of the HBR-16 and an old NC100 receiver that I may someday bring out of the attic and bring back to operational status, but that is pretty far down on the priority list for me. > > Enjoy SKN and listen to those old transmitters (and even listen on your vintage receiver).
