Message-ID: Hey everyone, quick question. I built my K2 over seven years now and just realized I had never completed the mic section. Granted, I didnt have my ticket at the time, so... Anyway, I recently picked up a d104 mic with a T-UG8 base (the one with the adjustable preamp in the base). I have not really verified the wiring in the base; it looks rather poor in parts, like someone did it with a dirty iron tip or whatnot but otherwise looks okay. The mic came with an old four pin connector. The cord itself has three wires plus the copper braid/shield: black, red, and white. In wiring it to a standard eight pin female, white went to pin 1, red to pin 2, copper braid to pin 7, and black to pin 8. On the P2 jumper, I jumpered it as per the KSB2 manual for Kenwood for AF, PTT, and the two grounds. That said, on keying the mic, the K2 goes silent but there is no evidence on the S meter that anything is happening. FWIW I have replaced the 9v battery in the base and attempted the same after adjusting the preamp pot to each extreme. Do I need to jumper the other pins on P2 as per the KSB2 instructions? Do I have the female connector wired correctly? Or perhaps I should revisit the wiring on the preamp and make sure someone else didn't Bubba it in the past... Any hints, suggestions or help would be most appreciated.

In-Reply-To: References: Message-ID: <56376072.7020906@blomand.net> There's several ways the wiring in the mike base can be done. There's two switches associated with the grip-to-talk bar on the T-UG8 base. I suggest, if not on the inside of mike base, you GOOGLE Astatic D-104 and get a schematic. You will need to use the amp in the base in as much as the K2 mike input Z is much too low for the mike element. Thus the amp serves as an emitter follower with gain to provide a proper Z for the mike element and drive the lower Z provided by the K2 mike input. {The D-104 element likes to see 3.0 megohms to 4.7 megohms input Z.} The mike cable will have two conductors which will be the PTT circuit and a shielded conductor for the audio. Schematics will be of great help in figuring out what needs to be done in terms of wires connected to the terminal strip in the base of the mike. 73 Bob, K4TAX On 11/1/2015 9:30 PM, Reuben Popp wrote: > Hey everyone, quick question. > > I built my K2 over seven years now and just realized I had never completed > the mic section.

To get started... Make sure that CONFIG: KAT3 is *not* set to "not inst". Be certain of that by hitting the "ANT" and "RXANT" buttons that you are on the coax connector you intend. After that there is the possibility that connecting the mini-coax you may not have seated the mini-coax connectors correctly. When fully seated, the little tabs on the connectors should be nearly up to the shoulder of the mini-coax jacks. 73, Guy K2AV On Mon, Nov 2, 2015 at 10:18 AM, Udo Langenohl - DK5YA wrote: > Gents, > > in spring I made an upgrade to my K3 (#59xx) with the internal ATU KAT3A. > After this I guessed that there is a noise drop on all bands from 160 up to > 10, but was not 100% sure.

I do have the cables as shown on Figure 9.17, page 189 of the ?Elecraft KX3 - Portable", with one exception: the Keyline interrupter is physically connect to the K3 Acc port, and the KPAK3AUX cable is connected to it and goes to the KAT500. The genders of the plugs on the Keyline Interrupter only allowed this connection, to the K3 rather than to the KAT500. Connecting the Keyline Interrupter to the K3 directly is shown in the Elecraft KAT500 owners manual in Figure 2, so I believe that is the correct way to do it. I do not have a ground wire connected from the KX3 to my shack common ground, though I would not think that is a contributing factor to what I am experiencing. That is something I could test. If I keep the K3 powered on, then everything seems to work ok: both the K3 and the KX3 can key the amplifier. It is just that, when using the KX3 to drive the amp and with the K3 on, the K3 needs to be on the same band as the KX3 to prevent band switching conflicts between the two transceivers. Thanks again and need to do that one test to add ground. 73, Hoop K9QJS On Nov 2, 2015, at 8:50 , James Bennett wrote: Hoop - Something must not be cabled properly.

I can?t easily check the cables on the back of my K3 as it is on a multi-tier desk shelf and would be ugly getting to it. The one thing that I have different in my cable scheme is that the line coming from the KX3 ACC2 jack goes into a Y-connector. One side of that goes to the KAT500 PTT and the other side goes into a small homebrew, handheld box with (1) a momentary PTT button and (2) an on-off toggle switch. This affords me the ability to have a hand-held PTT when I operate SSB (seldom) and not use VOX or have to press a button on the KX3. I do notice that you are using an evidently newer version of Fred?s book. Mine is simply titled ?The Elecraft KX3? and in that one the diagram is on page 147, but it still marked as figure 9.17. I wouldn?t think the diagram has changed, but maybe if Fred is reading this post he can comment.

The configuration file contains the serial number and calibration information specific to the K3 you're saving the configuration file for. I think you can print out the configuration files for each K3 and compare them. Then change only the parameters that are not K3 specific. There was an earlier thread that addressed a possible way to remove the specific K3 information from the configuration file and only load the non K3 specific parameters. I don't remember the details or even if it was determined that it was possible. You will have to search the archives.

Message-ID: I've noticed that, in my and other KX-1s, the sidetone sounds distorted. I am looking for methods of cleaning up the sidetone so that it will be easier for me to get on the same frequency as the other station by matching my sidetone (600Hz) to that of the incoming signal. Looking at the KX-1 schematic, it may be possible to add some R or C, between the junctions of R12 and R13 and the input to C2, to roll off the harmonics in the sidetone.

I'm old enough to remember that when I first built a VFO (ca 1953), if I wasn't responding to a CQ I was always careful to be sure there was at least one QSO between the frequency I was planning to use and the band edge. That way I had a decent chance of being "in band" since I really had little idea what frequency I was on otherwise. (And it wasn't remarkable that the station I was working wasn't particularly sure either.) 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Gary Sent: Monday, November 2, 2015 2:04 PM To: Bob McGraw - K4TAX; elecraft at mailman.qth.net Subject: Re: [Elecraft] 10 mHZ external reference VS the K3S's optionalKTCXO3-1 Bob, Thanks for asking, I too have struggled to understand the need given I only use the original digital mode, CW and SSB. :-) Gary -----Original Message----- From: "Bob McGraw - K4TAX" Sent: ?3/?11/?2015 7:56 AM To: "elecraft at mailman.qth.net" Subject: Re: [Elecraft] 10 mHZ external reference VS the K3S's optionalKTCXO3-1 Yes, I've been following this as well.

I have the macro set up to toggle split now. What goes wrong? Wrong antenna was one thing. How I end up with ANT instead of ANT1 is beyond me. I don't have the problem anymore, probably because I've gone through every band and mode memory and I've finally got everything on the proper antenna, including using the KAT utility to disable unused antenna ports. Seeing things in split doesn't mean you hear SUB, so make sure the SUB is displayed in the K3S and you should be good. Split and Sub are not the same, but they are both great features. When I use the SPLIT macro, I have it set both SPLIT and SUB and then I tab SUB if I don't want to hear the SPLIT frequency. Then, when I'm finsihed with split, the PF key sets things to NORMAL again. 73, Byron On 11/02/2015 05:58 PM, Amateur Radio Operator N5GE wrote: > I'm trying to set-up working Split Folowing Fred Cady's K3s manua land > I'm having trouble setting it up on 17m.

I now have a digital peak power meter between the K3 and KPA500 and I can see the surges. The power output from the K3 is steady apart from these brief bursts. The power will change from typically 25 to 30 watts to anything up to the full 100 watts. The KPA500 gives a soft or hard alarm depending on how high the burst is. I have tried running into a dummy load and the same thing happens. These surges are random but they appear to be more frequent on the lower bands - with different antennas and dummy load. The surges appear to be more likely to occur within a minute or so of changing the power output from the K3 - either up or down. I run the KPA500 between 400 and 500 watts to achieve 400 watts at the antenna feed point as per UK limits. This means that I also see surges that do not cause an alarm but briefly light the red power LEDs. I was up to date with all firmware when I last checked about 3 weeks ago. I have done the Tx power calibration. Any ideas?

If it only occurs on 1 or 2 bands you may need to manually touch up the results from the TX Gain Calibration on the affected bands. If the overshoot is seen on most bands then it is probably a different problem. A method is explained at the top of page 62 of the K3 manual for TXGN{pwr}. Go to the affected band, turn off CONFIG:TX ALC and set the CONFIG:TXGN number for that band to a lower number. Remember to turn CONFIG:TX ALC back on after changing the number. Retest. 73, Mike K2MK gi4doh wrote > With my K3/KPA500/KAT500 combo I occasionally get a soft or hard alarm on > the KPA500 due to the K3 briefly giving a high power burst. > I now have a digital peak power meter between the K3 and KPA500 and I can > see the surges. > The power output from the K3 is steady apart from these brief bursts.

What antenna is connected to the Sub-RX? Is the Sub-RX on? Many K3 settings are "by band," so making a change on one band does not carry through to other bands. This is often the cause of the K3 doing something you don't expect. :) BTW -- K3 and K3S operate the same, the K3S is simply the latest improved hardware. A good move when doing anything with the Sub RX or second VFO is to copy settings for the Main RX to the second VFO or Sub RX by quickly pushing A>B twice in succession. If you want to work split, do that first, then immediately tune the 2nd VFO to the desired split (so you don't TX on top of the DX). 73, Jim K9YC From w3fpr at embarqmail.com Tue Nov 3 14:14:07 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 3 Nov 2015 14:14:07 -0500 Subject: [Elecraft] Working Split with K3S In-Reply-To: References: Message-ID: <5639077F.5040302@embarqmail.com> Tom, SPLIT and the SubRX are two different things - try not to get them mixed up. The SubRX normally receives using VFO B (unless in DIVERSITY), but that is not the same as SPLIT. With SPLIT off, transmit will be on the VFO A frequency. When SPLIT is ON, transmit will be on the VFO B frequency. That is true whether the SubRX is turned on or off. Do a check - turn SPLIT off. Now can you hear both the main and SubRX? If not, do you really have SUB turned on? You should see the SUB icon in the display. If SUB is turned on, then check the antenna that the SubRX is using - use BSET and see if AUX appears in the display, if it does, then the SubRX is listening to the AUX antenna - which would be either the BNC ant connector or the non-transmit antenna (depends on how your SubRX AUX input is physically connected). Turn AUX off if it is turned on so the SubRX will listen to the main antenna (the same one used for transmit). You should be able to hear both the main and the SubRX. Once you can hear both, turn on SPLIT - observe that the arrow in the right of the display points to VFO B. The SubRX should still be heard. 73, Don W3FPR On 11/3/2015 1:33 PM, Amateur Radio Operator N5GE wrote: > I'm trying to set-up working Split Folowing Fred Cady's K3s manua land > I'm having trouble setting it up on 17m.

Its commonly thought that its a phase locking system (which it is not doing). Basic frequency accuracy and stability is established by the TCXO in the K3 which provides frequency reference to the VFO's. Per Elecraft K3 manual - page: TCXO-1 is 5ppm and TCXO-3 is 1 ppm Using 28-MHz as an example: 5ppm = 28 E+6 x 5 E-6 = 28 x 5 = 140 Hz 1ppm = 28 E+6 x 1 E-6 = 28 Hz note these are +140 to -140 Hz and +28 to -28 Hz My measurement show that EXREF improves this to 0.1ppm 0.1ppm = 28 E+6 x 1 E-7 = 2.8 Hz* *ONLY IF you have the TCXO-3 installed. Also the TCXO is in warm-up for the first ten minutes after the K3 is powered on. EXREF corrects all the warm-up drift, as well, so you can start using the radio immediately without frequency accuracy concerns. HOW: The EXREF ckt provides a more accurate 10-MHz reference for the TCXO to be compared with about every 4-seconds. If the TCXO is off frequency during the 4-second interval then sw writes an offset to the TCXO to bring into agreement with the reference. Drift is no different than running the TCXO alone. The improvement is that drift is only allowed a few seconds between corrections which provides the improved accuracy. Stability is still that of the TCXO that is installed.

While locked to the external source, the K3's reference oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not phase lock the K3's reference oscillator, the external 10 MHz source has no impact on the K3's phase noise performance.

The most probable cause is a defective solder connection in the BFO area. Carefully lift L33 and reflow the soldering of the BFO crystals. Reflow the soldering of C173 and C174, RP6. D37, D38, C169 and Q24. Make certain when you replace L33 that the leads of the resistor are well soldered and the leads of L33 are soldered to the resistor leads. 73, Don W3FPR On 11/3/2015 6:58 PM, K1FFX wrote: > I posted a query about this a few years ago and it remained largely > unresolved at the time. > > The "end user" symptom was and is that filters would over time "drift" > (there's probably a better technical term) out of alignment, requiring a CAL > FIL operation.

The reason I would want the marker is to quickly set it on a signal that has already progressed down the screen. I can't because basically there's no marker. If I just wait for it, desired signal is gone. Why can't the marker in the waterfall just be an extension of the one in the spectrum so you can use it? Is there some technical reason?

Imagine a mountaintop station with 16 yagis stacked often arranged to cover 360 degrees and running 3kW PEP output as some are permitted to do. Most normal transceivers even with fairly good transverters will fall apart under those circumstances. I have encountered receive systems that couldn't handle a line of sight station that was running 100 watts and a single antenna without overloading. You don't say how serious you are in 144 MHz contesting, and whether you already own a K3 or a KX3 and whether you already have the XV144 transverter, so it is difficult to know what your question is and give you an answer. The K3 would certainly be the better contest radio, though of course more expensive once you load it is with filters. The nice thing is you can add just the options you require, if you don't need HF and 100 watts etc. However there are better transverters available for contesting on 144 MHz than the XV144. There is the very expensive Kuhne TR 144 H , and the M+E ME2T Pro from HA1YA. The very best is needed for serious contest use. If you want to build something there is the Javornik. Now we have the G4DDK Anglian transverter kit available which is also good by all accounts. GM3SEK has recently built an Anglian transverter and PA -inside- his K3/10. The Anglian LO can be injection locked to 10 MHz too. HA1YA also makes banks of IF switched xtal filters that go between the transceiver and the transverter at the IF to further improve strong signal handling when you have close strong signals in contests. I live on the extremity of Europe and have only a few local strong signals to contend with, so rarely encounter huge problems with receiver overload, more commonly it is the poor quality of transmitted signals that causes problems ( IMD from over driven amplifiers and transmitted wideband phase noise from poorly designed systems). So I am happy with my KX3 with an ME2T Pro transverter at 14 MHz IF. However if I lived in Central Europe I would probably need something a little better and would certainly consider the K3S. Having the PX3 panadaptor is also nice for finding stations (search and pounce) on the band, it also shows very graphically the difference between a good narrow SSB signal and one that is being over driven and splattering. 73 David Anderson GM4JJJ > On 4 Nov 2015, at 10:32, Samir Popaja <7s7v at comhem.se> wrote: > > Hello, > > Is any difference between those two combo in prestanda for contesting?Will use only for contesting in Europe... > > Skickat fr?n min iPhone > ______________________________________________________________ > 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 gm4jjj at yahoo.co.uk From w3fpr at embarqmail.com Wed Nov 4 08:05:56 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Wed, 4 Nov 2015 08:05:56 -0500 Subject: [Elecraft] Microphone Setup In-Reply-To: <000901d116b3$285aee60$7910cb20$@yahoo.com> References: <000901d116b3$285aee60$7910cb20$@yahoo.com> Message-ID: <563A02B4.6050108@embarqmail.com> Dr. Jim, There is no FAQ that I am aware of. Actually the information is pretty basic. Microphone elements come in two basic types - Electret and Dynamic. The Electret types need a DC bias applied to the AF line. The Dynamic elements should *not* have bias applied or they will be distorted. The other thing that often causes confusion is the mic plug pinout. The mic plug wiring must match the pin arrangement used in the transceiver, and that information is shown in the transceiver manual. In the case of the Elecraft K3 and K3S, the 8 pin mic pinout differs only from that used by Kenwood in that the use of pins 5 and 6 are reversed. Since most Kenwood unamplified dynamic microphones do not use pins 5 and 6, most all Kenwood dynamic microphones will work directly with the K3 and K3S. Heil microphones normally use a 4 pin XLR as a generalized connector *and* use an adapter or special cable to change that XLR connection to that required for the transceiver. The adapter to be used with the K3 and K3S is the one for the Kenwood (which has a red band). Heil microphones come in both the dynamic and the electret types, although most are dynamic. If the microphone is designated with a "-iC" or "-K2" it is an electret type. A lot of information on microphones and transceiver connections can be found at http://homepage.ntlworld.com/rg4wpw/date.html. G4WPW has done an excellent job of collecting information about microphones, mic pinouts and even schematics. In your particular case with the Heil PR-781, use the Kenwood cable (Heil CC-1XLR-K) with that microphone and make certain the bias is turned off. I believe that microphone has a rather low output, so you may have to use the high range for the mic gain. So - the K3(S) MIC SEL menu should be set to "FP H". Set the mic gain as described in the K3 manual - first set compression to zero, then adjust the MIC GAIN until you see 5 to 7 bars illuminated on the ALC meter (that can be done in TX TEST so no RF is produced). Then bring the compression up to your tastes, usually in the 3 to 6 dB range. 73, Don W3FPR On 11/3/2015 10:44 PM, James F.

The voice coil move in one direction depending on the polarity. Now think of a dynamic mic element doing the same thing. After all, electrically, the element and speaker are essentially the same. The DC bias causes the mic element's static condition to be physically moved from its normal resting position, so the output waveform will not be an accurate electrical representation of the audio wavefront arriving at the element. 73, Charlie k3ICH From rmcgraw at blomand.net Wed Nov 4 09:01:15 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Wed, 4 Nov 2015 08:01:15 -0600 Subject: [Elecraft] Microphone Setup In-Reply-To: <000901d116b3$285aee60$7910cb20$@yahoo.com> References: <000901d116b3$285aee60$7910cb20$@yahoo.com> Message-ID: <563A0FAB.8040503@blomand.net> Jim: I use the PR -781 on my K3S with excellent results.

Message-ID: Am I doing something wrong or is this just how it works? I have the P3's waterfall marker turned on. The "marker" slowly crawls down the screen toward the bottom. Moving the Select knob drags the top of the marker and the rest slowly follows drawing a snake. Cute but...huh? Question: What good is this? The reason I would want the marker is to quickly set it on a signal that has already progressed down the screen. I can't because basically there's no marker. If I just wait for it, desired signal is gone. Why can't the marker in the waterfall just be an extension of the one in the spectrum so you can use it? Is there some technical reason? I'm used to using software for this and none of them work like this. Am I missing a setting somewhere? I've looked hard.

While locked to the external source, the K3's reference oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not phase lock the K3's reference oscillator, the external 10 MHz source has no impact on the K3's phase noise performance.

Thanks for the specific and detailed hints, Don (and thanks also to Matt and Bob for helpful e-mails). I decided to defer handling L33 and the two BFO crystals. I went ahead and reflowed the soldering for the other components. This has fixed the immediate problem: the center frequencies moved "up" and was I able to easily align all the filters. Hopefully, this will be a permanent fix and there will be no further significant BFO drift. If I continue to see drift, then I'll go ahead deal with L33 (whose solder joints all looked fine to me yesterday) and reflow the BFO crystals' soldered leads.

Geomagnetic storms can have interesting effects on the ionosphere and on radio wave propagation. Some years back there was a storm that pretty much killed all the ham bands on HF. I tuned around the bands and heard almost no activity. I eventually ran across two hams talking each other. Both of them had very good signals when I could hear so little activity. One person was in VK land (about the opposite side of the world for me). I forget where the other one was located. -- Cheers!

It's actually not too bad an idea, considering that signals are always heading to the bottom of the waterfall, but currently the marker's latest position is at the top of the waterfall.

If not, then most of my early electronics training was fanciful and my Elmers would be embarrassed were they not SK. It all depends upon whether you think of electrons or the spaces (holes) electrons fill as they migrate. Picture a straight row of coins on a tabletop. Mark the location for each coin. Now remove a coin at one end. That represents your power source pulling an electron away from an atom at the positive end of the power supply. Start shuffling the coins from one side to the other beginning at the end with the missing coin to fill it's gap, carefully moving one coin at a time to the marks keeping the gap open. Note that the coins (electrons) are moving in one direction as electrons move from negative to positive while the gap (hole) moves in the opposite direction from positive to negative. 73, Ron AC7AC From dmb at lightstream.net Wed Nov 4 09:22:19 2015 From: dmb at lightstream.net (dmb at lightstream.net) Date: Wed, 4 Nov 2015 09:22:19 -0500 (EST) Subject: [Elecraft] P3 - Waterfall Marker?

I don?t intend to use my antenna on 160 meters. I use the KAT500 with my 80-meter dipole fed by ladder line and a 4:1 Balun to Coax for last 20 feet. This antenna works excellently in concert with the KAT500 for 80, 40, and 30 meter bands. I don?t use it with other bands. This weekend, I was curious as to how close (or far) the KAT500 could bring the antenna in for the 160 meter band. I knew that it would not work though I was wondering how bad it would be. So, as I expected, the tuning never closed in on a descent SWR, the best I saw on one test only was SWR about 49:1 as reported by the KAT500 utility. But, the BYPASS SWR reported was about 11:1. Further tests showed varying bad reports of incomplete tuned SWR while also showing a much lower BYPASS SWR (under 13:1). According to my own tests of the impedance for the antenna on 160 meters, the BYPASS SWR is bogus. So, I am assuming that unless the KAT500 reaches a tuned SWR value under 1.5:1 (or, whatever threshold I set), the BYPASS SWR is totally meaningless. 73, phil, K7PEH From reuben.popp at gmail.com Wed Nov 4 16:06:44 2015 From: reuben.popp at gmail.com (Reuben Popp) Date: Wed, 4 Nov 2015 15:06:44 -0600 Subject: [Elecraft] MAB boards for the K2?

At certain lengths, it will act as an impedance transformer and could load your 80m dipole quite well. An 80m dipole on 160 will have a low impedance at the feed point. A quarter wave of ladder line will transform that impedance to a higher impedance. A half wave of ladder line will give the same impedance (no transformer effect.) If you have something near a half wave of ladder line, the 4:1 balun is totally wrong since it will transform a low impedance to one 4x lower! Try it with a 1: balun and see if the SWR improves or not. As for actual, honest SWR readings, I assume that most meters are unreliable in the actual readings when the SWR gets high, especially 10:1 and above. They are really built to operate in the 50 ohm range, not 500 or 1000. BTW, IMO the KAT500 is one of the best tuners I've used and I've been building or using them for over 50 years.

Some SWRs are simply too difficult to measure accurately, even with an error-corrected network analyzer. For near ideal reactances or very high or very low SWR, reflection measurements are inappropriate. In other words, if the impedance is on or near the periphery of a Smith Chart (rho ~ 1) find another method.

The radiation resistance on 160 will be very low and the 4:1 transformer will divide it by 4, meaning just a tad above 1 ohm. It is also very reactive. If you really want to use it on 160, try shorting the ladder line at the feed end, remove the transformer, and connect the shorted end to the coax through a variable cap. Run 1 or 2 wires on the ground from the coax shield and see if you can feed it as a Marconi-T. If your ladder line is 60 ft long, feed Z at the shorted end of the ladder line will be about 110+j1400 and an Xc of 1400 ohms will probably work fine for the KAT500. > > So, as I expected, the tuning never closed in on a descent SWR, the > best I saw on one test only was SWR about 49:1 as reported by the > KAT500 utility.

In-Reply-To: References: Message-ID: <563AB1BC.9040802@embarqmail.com> David, The KAF2 is mainly for CW use. It provides a great peaking filter at the frequency that you have set it to (presumably your sidetone pitch). It also has a low pass filter that is in-circuit at all times. That can reduce band noise hiss for all modes. The KDSP2 also provides filtering for CW, SSB and data modes. If you are bothered by signals nearby in frequency, the straight-sided filters of the KDSP2 will be an advantage. The KDSP2 also provides noise reduction algorithms, although turning on NR in any transceiver can introduce distortion for voice signals. How bad that is will be determined by the aggressiveness of the algorithms. The KDSP2 does allow a wide range of settings, and you may have to experiment with those setting if the defaults do not satisfactorily handle your particular noise situation. So, not directly answering your question, the KDSP2 can provide filtering as good as the KAF2 (even better), but if the operator is CW oriented, the additional cost of the KDSP2 option may not provide the improvement expected - for SSB operation, there is no choice, the KAF2 is not useful on SSB (other than the Low Pass Filter) and the KDSP2 is the only real choice between the two. 73, Don W3FPR On 11/4/2015 6:44 PM, David Inger wrote: > A friend has a fairly recent K2 with the KAF2 audio filter option.

In-Reply-To: References: Message-ID: When I built my K2 a year and a half ago, I also had to decide between bare K2 vs KAF2 vs KDSP2, and went through the archives. In the end I went with the KDSP2, but some of the points I considered along the way: Bare K2: - built-in IF filters do work very well, but I read some reports that strong stations nearby can produce some ??blow-by??, and that either the KAF2 or KDSP2 can help clean it up. - At some point, Elecraft may cease production of the K2, and if I leave my K2 bare, I may not get the chance to upgrade it later. KAF2: - cheap, very easy to use - for CW, reports seem to indicate it performs about the same as the KDSP2 - has a nice LPF stage that cuts down background hiss, seems to be better than the KDSP2 in this regard. Some people have added a KAF2-style LPF to their KDSP2 with good results. KDSP2: - much more configurable than KAF2 - has noise reduction feature, I thought this might come in handy if I have the K2 as a second radio, and have it sitting on my club?s SSB calling frequency. It does keep the radio very quiet, almost like a voice squelch. - also has automatic notch filter, in case I need it - can go very narrow. I had good experiences with the DSP filtering in my KX3, which was really effective in digging out some very weak sigs on our QRP net (although so far I have mainly used the K2 for rag chewing, haven?t really done any side-by-side comparisons with KX3) - Code for the DSP is open source, so might be fun to play with. However, I think the development kits are now out of production, and I think maybe the chip in my KDSP2 was not in a socket, but soldered directly to the board (someone correct me if I am wrong). So, there are some barriers to playing with the DSP code, and if I wanted to experiment in DSP techniques, a much easier way would probably be to use a generic PC with sound card and GNUradio or similar development environment. - KDSP2 chews a lot more power than KAF2, which may be an issue if you like to run off batteries. You can disable the KDSP2 through the menu, which significantly reduces but doesn?t eliminate the additional power draw. If you power-cycle the K2, the disable setting of the KDSP2 is forgotten, and the KDSP2 will become active again. - the KDSP2 is a lot more complicated to use than KAF2. This means you have more flexibility, and some people like having lots of settings to play with, so it can be a plus. But it can also be a minus as it can be hard to remember how to change some of the less commonly adjusted settings. Having said that, the defaults on the KDSP2 are usually fine.? So, is the KDSP2 a worthwhile upgrade? For your SSB friend, I would say yes. For a primarily CW operator like yourself who already has a KAF2, it might be harder to justify. Is the upgrade cost-effective? Well, the KDSP2 is significantly more expensive than the KAF2, and it is a personal choice whether the extra value/fun brought by the KDSP2?s additional features warrants the additional cost. After all, it is a hobby :-) --? 73 de Matt VK2RQ On 5 novembre 2015 at 10:44:52 AM, David Inger (ingerassociates at cox.net) wrote: A friend has a fairly recent K2 with the KAF2 audio filter option.

This is one of those ideas that, while having a solid theoretical basis, doesn't hold up once you plug numbers into the problem. That's because the bias voltage is typically provided from a rather high impedance source, so the bias current is too low and the sound pressure level is too low to drive the diaphragm anywhere near its limits. The simple fact is that it's virtually impossible to overload a dynamic mic. One major mic manufacturer advertised that their dynamic mics could reproduce a gunshot without distortion. It wasn't a lie -- almost any pro dynamic mic can do that. When you hear distortion from a dynamic mic, it's the mic producing enough output to overload the mic preamp, and the solution is to either reduce the preamp gain or add a pad (passive attenuator). Controls to do both are built into the mixers used for live sound, broadcast, and recording. 73, Jim K9YC From lightdazzled at gmail.com Wed Nov 4 21:25:24 2015 From: lightdazzled at gmail.com (Chip Stratton) Date: Wed, 4 Nov 2015 21:25:24 -0500 Subject: [Elecraft] MAB boards for the K2?

Some dynamic mikes I've encountered do use a transformer to get the voltage level from the very low impedance Z element to a respectable output value. Running a bit of DC through the transformer on the secondary side could tend to cause some DC saturation. And transformers which are not designed to handle DC can behave a bit odd under this condition. Other dynamic mikes I've encountered provide an internal DC blocking capacitor to prevent this issue, although that in itself has its issues. Yes, with any dynamic mike being used, set the bias to the off position.......just to be safe. And don't worry about overloading a dynamic mike, but do be concerned with the preamp or first analog stage being driven into distortion. 73 Bob, K4TAX On 11/4/2015 7:54 PM, Jim Brown wrote: > This is one of those ideas that, while having a solid theoretical > basis, doesn't hold up once you plug numbers into the problem.

And Don Wilhelm reminded me that some mics used with a K2 didn't like bias. That can, of course, depend strongly on the value of the bias source resistance. 73, Jim K9YC From jboehner01 at yahoo.com Wed Nov 4 22:14:54 2015 From: jboehner01 at yahoo.com (James F.

Boehner, MD; elecraft at mailman.qth.net Subject: Re: [Elecraft] Microphone Setup Dr. Jim, There is no FAQ that I am aware of. Actually the information is pretty basic. Microphone elements come in two basic types - Electret and Dynamic. The Electret types need a DC bias applied to the AF line. The Dynamic elements should *not* have bias applied or they will be distorted. The other thing that often causes confusion is the mic plug pinout. The mic plug wiring must match the pin arrangement used in the transceiver, and that information is shown in the transceiver manual. In the case of the Elecraft K3 and K3S, the 8 pin mic pinout differs only from that used by Kenwood in that the use of pins 5 and 6 are reversed. Since most Kenwood unamplified dynamic microphones do not use pins 5 and 6, most all Kenwood dynamic microphones will work directly with the K3 and K3S. Heil microphones normally use a 4 pin XLR as a generalized connector *and* use an adapter or special cable to change that XLR connection to that required for the transceiver. The adapter to be used with the K3 and K3S is the one for the Kenwood (which has a red band). Heil microphones come in both the dynamic and the electret types, although most are dynamic. If the microphone is designated with a "-iC" or "-K2" it is an electret type. A lot of information on microphones and transceiver connections can be found at http://homepage.ntlworld.com/rg4wpw/date.html. G4WPW has done an excellent job of collecting information about microphones, mic pinouts and even schematics. In your particular case with the Heil PR-781, use the Kenwood cable (Heil CC-1XLR-K) with that microphone and make certain the bias is turned off. I believe that microphone has a rather low output, so you may have to use the high range for the mic gain. So - the K3(S) MIC SEL menu should be set to "FP H". Set the mic gain as described in the K3 manual - first set compression to zero, then adjust the MIC GAIN until you see 5 to 7 bars illuminated on the ALC meter (that can be done in TX TEST so no RF is produced). Then bring the compression up to your tastes, usually in the 3 to 6 dB range. 73, Don W3FPR On 11/3/2015 10:44 PM, James F.

This just won't be the case in the real world. The VFO-B voltage indication is reliable in terms of the voltage in receive vs. the voltage in transmit. I think it reasonable to accept < 0.5 volt drop or less between RX and TX at 100 watts output. Do consider the regulation of the supply. Measure that with a good DVM at the supply terminals. And here, it is reasonable to expect less than 0.1 volt change between RX and TX at 100 watts. Many of the better supplies will be in the < 0.01 volt range under this condition. If one finds more voltage drop than expected, then further investigation is suggested. Are the terminals properly crimped and soldered on both ends? Are the terminals tight fitting? Is the wire gauge correct for the current demand and length? Are there other devices between the supply and radio that will contribute to voltage drop? These are a few questions to be answered. Better regulation and maintaining a voltage at the radio between 13.5 and 14.5 will make for a cleaner transmitter in respect to transmitted IMD. And that topic was "beat to death" in a previous discussion. If the supply is not well regulated, be sure the voltage at the radio will never exceed 15.0 volts. 73 Bob, K4TAX On 11/5/2015 7:36 AM, ok1rp wrote: > Hi Jeff, > > many thanks for your post regarding the soldering Anderson Plug leads > connections. > It seems that I should check it too as I have 0.7V drop RX/TX on VFO-B line > measurement. > (even although I never had any problem regarding the low voltage...) > > It is good hint for my old timer K3 (#778) although it work like champ now.

Message-ID: While many people recommend soldering crimped connectors, such as Anderson Power Poles, it is not a very good idea. The reason(s) it is neither required, nor desired, is partially as follows: 1. A PROPERLY crimped connection creates a molecular bond between the conductor and the connector that is more conductive than soldering. 2. The soldering process causes corrosion because even rosin core solder is slightly acidic. 3. The solder that flows into or onto the conductor (wire) causes it to stiffen and increases the probability that vibration or movement will cause the wire to break at that point. 4. The annealing of the copper wire is altered which also increases the possibility of wire breakage due to vibration or movement. It is absolutely necessary that the proper tool be used for the connection being crimped. If you are going to use a crimped connection it is imperative that you have a tool that matches the connector. If you do not have the proper tool then DO NOT use crimped connections.

If your crimps fail over time there's an issue with the crimp or there's extreme physical stress that's causing the crimp to fail. Part of my background is Military Avionics. Our connections are constantly subject to vibration, changing temperature, and changing humidity. I've never seen a proper crimp fail. I've replaced crimps after the pins were broken from improper mating or such. In the environment I came from it was common to re-work soldered connectors due to conductor breakage over time (consider the platform I flew on was from the 1960s). Validate the connectors are rated for the wire gauge/type please.

Message-ID: Content-Type: text/plain; charset="us-ascii" A friend has a fairly recent K2 with the KAF2 audio filter option. He asked me to remove the KAF2, build the KDSP2 board and install it in his K2. This got me to thinking: I also have a K2 wiht the KAF2 installed. My friend works mainly SSB; I work main CW and digital modes. Is the DSP board a significant improvement over the bare K2 or even with the KAF2 installed (which seems to be tailored for CW reception)? In general, radios that I have owned with AF DSP have been pretty much a disappointment. So is the KDSP2 a worthwhile and cost-effective upgrade? 73 de K6SBA David in Santa Barbara, CA ------------------------------ Message: 2 Date: Thu, 5 Nov 2015 08:44:51 +0900 From: "Atsu Taniguchi" To: elecraft at mailman.qth.net Subject: [Elecraft] WTB: KPA500 Message-ID: Content-Type: text/plain;charset=iso-2022-jp Anyone who can sell and ship used KPA500 to Tokyo with reasonable price please contact off the list.

Message-ID: <563AB1BC.9040802 at embarqmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed David, The KAF2 is mainly for CW use. It provides a great peaking filter at the frequency that you have set it to (presumably your sidetone pitch). It also has a low pass filter that is in-circuit at all times. That can reduce band noise hiss for all modes. The KDSP2 also provides filtering for CW, SSB and data modes. If you are bothered by signals nearby in frequency, the straight-sided filters of the KDSP2 will be an advantage. The KDSP2 also provides noise reduction algorithms, although turning on NR in any transceiver can introduce distortion for voice signals. How bad that is will be determined by the aggressiveness of the algorithms. The KDSP2 does allow a wide range of settings, and you may have to experiment with those setting if the defaults do not satisfactorily handle your particular noise situation. So, not directly answering your question, the KDSP2 can provide filtering as good as the KAF2 (even better), but if the operator is CW oriented, the additional cost of the KDSP2 option may not provide the improvement expected - for SSB operation, there is no choice, the KAF2 is not useful on SSB (other than the Low Pass Filter) and the KDSP2 is the only real choice between the two. 73, Don W3FPR On 11/4/2015 6:44 PM, David Inger wrote: > A friend has a fairly recent K2 with the KAF2 audio filter option.

Message-ID: Content-Type: text/plain; charset="utf-8" When I built my K2 a year and a half ago, I also had to decide between bare K2 vs KAF2 vs KDSP2, and went through the archives. In the end I went with the KDSP2, but some of the points I considered along the way: Bare K2: - built-in IF filters do work very well, but I read some reports that strong stations nearby can produce some ??blow-by??, and that either the KAF2 or KDSP2 can help clean it up. - At some point, Elecraft may cease production of the K2, and if I leave my K2 bare, I may not get the chance to upgrade it later. KAF2: - cheap, very easy to use - for CW, reports seem to indicate it performs about the same as the KDSP2 - has a nice LPF stage that cuts down background hiss, seems to be better than the KDSP2 in this regard. Some people have added a KAF2-style LPF to their KDSP2 with good results. KDSP2: - much more configurable than KAF2 - has noise reduction feature, I thought this might come in handy if I have the K2 as a second radio, and have it sitting on my club?s SSB calling frequency. It does keep the radio very quiet, almost like a voice squelch. - also has automatic notch filter, in case I need it - can go very narrow. I had good experiences with the DSP filtering in my KX3, which was really effective in digging out some very weak sigs on our QRP net (although so far I have mainly used the K2 for rag chewing, haven?t really done any side-by-side comparisons with KX3) - Code for the DSP is open source, so might be fun to play with. However, I think the development kits are now out of production, and I think maybe the chip in my KDSP2 was not in a socket, but soldered directly to the board (someone correct me if I am wrong). So, there are some barriers to playing with the DSP code, and if I wanted to experiment in DSP techniques, a much easier way would probably be to use a generic PC with sound card and GNUradio or similar development environment. - KDSP2 chews a lot more power than KAF2, which may be an issue if you like to run off batteries. You can disable the KDSP2 through the menu, which significantly reduces but doesn?t eliminate the additional power draw. If you power-cycle the K2, the disable setting of the KDSP2 is forgotten, and the KDSP2 will become active again. - the KDSP2 is a lot more complicated to use than KAF2. This means you have more flexibility, and some people like having lots of settings to play with, so it can be a plus. But it can also be a minus as it can be hard to remember how to change some of the less commonly adjusted settings. Having said that, the defaults on the KDSP2 are usually fine.? So, is the KDSP2 a worthwhile upgrade? For your SSB friend, I would say yes. For a primarily CW operator like yourself who already has a KAF2, it might be harder to justify. Is the upgrade cost-effective? Well, the KDSP2 is significantly more expensive than the KAF2, and it is a personal choice whether the extra value/fun brought by the KDSP2?s additional features warrants the additional cost. After all, it is a hobby :-) --? 73 de Matt VK2RQ On 5 novembre 2015 at 10:44:52 AM, David Inger (ingerassociates at cox.net) wrote: A friend has a fairly recent K2 with the KAF2 audio filter option.

This is one of those ideas that, while having a solid theoretical basis, doesn't hold up once you plug numbers into the problem. That's because the bias voltage is typically provided from a rather high impedance source, so the bias current is too low and the sound pressure level is too low to drive the diaphragm anywhere near its limits. The simple fact is that it's virtually impossible to overload a dynamic mic. One major mic manufacturer advertised that their dynamic mics could reproduce a gunshot without distortion. It wasn't a lie -- almost any pro dynamic mic can do that. When you hear distortion from a dynamic mic, it's the mic producing enough output to overload the mic preamp, and the solution is to either reduce the preamp gain or add a pad (passive attenuator). Controls to do both are built into the mixers used for live sound, broadcast, and recording. 73, Jim K9YC ------------------------------ Message: 15 Date: Wed, 4 Nov 2015 21:25:24 -0500 From: Chip Stratton Cc: Elecraft Reflector Subject: Re: [Elecraft] MAB boards for the K2?

Some dynamic mikes I've encountered do use a transformer to get the voltage level from the very low impedance Z element to a respectable output value. Running a bit of DC through the transformer on the secondary side could tend to cause some DC saturation. And transformers which are not designed to handle DC can behave a bit odd under this condition. Other dynamic mikes I've encountered provide an internal DC blocking capacitor to prevent this issue, although that in itself has its issues. Yes, with any dynamic mike being used, set the bias to the off position.......just to be safe. And don't worry about overloading a dynamic mike, but do be concerned with the preamp or first analog stage being driven into distortion. 73 Bob, K4TAX On 11/4/2015 7:54 PM, Jim Brown wrote: > This is one of those ideas that, while having a solid theoretical > basis, doesn't hold up once you plug numbers into the problem.

And Don Wilhelm reminded me that some mics used with a K2 didn't like bias. That can, of course, depend strongly on the value of the bias source resistance. 73, Jim K9YC ------------------------------ Message: 19 Date: Wed, 4 Nov 2015 22:14:54 -0500 From: "James F.

Don, I am happy to say that the settings you mention below were the ones that I settled on after some experimentation prior to my post. I appreciate the validation and the background on the reasons why those settings are the desired ones. Not all information is in the manual, certainly not specifics. The collective experience on this list is greatly appreciated, especially from those of us that are new to the Elecraft line. Thanks again!

Boehner, MD; elecraft at mailman.qth.net Subject: Re: [Elecraft] Microphone Setup Dr. Jim, There is no FAQ that I am aware of. Actually the information is pretty basic. Microphone elements come in two basic types - Electret and Dynamic. The Electret types need a DC bias applied to the AF line. The Dynamic elements should *not* have bias applied or they will be distorted. The other thing that often causes confusion is the mic plug pinout. The mic plug wiring must match the pin arrangement used in the transceiver, and that information is shown in the transceiver manual. In the case of the Elecraft K3 and K3S, the 8 pin mic pinout differs only from that used by Kenwood in that the use of pins 5 and 6 are reversed. Since most Kenwood unamplified dynamic microphones do not use pins 5 and 6, most all Kenwood dynamic microphones will work directly with the K3 and K3S. Heil microphones normally use a 4 pin XLR as a generalized connector *and* use an adapter or special cable to change that XLR connection to that required for the transceiver. The adapter to be used with the K3 and K3S is the one for the Kenwood (which has a red band). Heil microphones come in both the dynamic and the electret types, although most are dynamic. If the microphone is designated with a "-iC" or "-K2" it is an electret type. A lot of information on microphones and transceiver connections can be found at http://homepage.ntlworld.com/rg4wpw/date.html. G4WPW has done an excellent job of collecting information about microphones, mic pinouts and even schematics. In your particular case with the Heil PR-781, use the Kenwood cable (Heil CC-1XLR-K) with that microphone and make certain the bias is turned off. I believe that microphone has a rather low output, so you may have to use the high range for the mic gain. So - the K3(S) MIC SEL menu should be set to "FP H". Set the mic gain as described in the K3 manual - first set compression to zero, then adjust the MIC GAIN until you see 5 to 7 bars illuminated on the ALC meter (that can be done in TX TEST so no RF is produced). Then bring the compression up to your tastes, usually in the 3 to 6 dB range. 73, Don W3FPR On 11/3/2015 10:44 PM, James F.

This just won't be the case in the real world. The VFO-B voltage indication is reliable in terms of the voltage in receive vs. the voltage in transmit. I think it reasonable to accept < 0.5 volt drop or less between RX and TX at 100 watts output. Do consider the regulation of the supply. Measure that with a good DVM at the supply terminals. And here, it is reasonable to expect less than 0.1 volt change between RX and TX at 100 watts. Many of the better supplies will be in the < 0.01 volt range under this condition. If one finds more voltage drop than expected, then further investigation is suggested. Are the terminals properly crimped and soldered on both ends? Are the terminals tight fitting? Is the wire gauge correct for the current demand and length? Are there other devices between the supply and radio that will contribute to voltage drop? These are a few questions to be answered. Better regulation and maintaining a voltage at the radio between 13.5 and 14.5 will make for a cleaner transmitter in respect to transmitted IMD. And that topic was "beat to death" in a previous discussion. If the supply is not well regulated, be sure the voltage at the radio will never exceed 15.0 volts. 73 Bob, K4TAX On 11/5/2015 7:36 AM, ok1rp wrote: > Hi Jeff, > > many thanks for your post regarding the soldering Anderson Plug leads > connections. > It seems that I should check it too as I have 0.7V drop RX/TX on VFO-B line > measurement. > (even although I never had any problem regarding the low voltage...) > > It is good hint for my old timer K3 (#778) although it work like champ now. ------------------------------ Message: 27 Date: Thu, 5 Nov 2015 10:18:36 -0500 From: Michael Blake To: Elecraft Reflector Subject: [Elecraft] Soldering crimped connectors is not a good thing. Message-ID: Content-Type: text/plain; charset="us-ascii" While many people recommend soldering crimped connectors, such as Anderson Power Poles, it is not a very good idea. The reason(s) it is neither required, nor desired, is partially as follows: 1. A PROPERLY crimped connection creates a molecular bond between the conductor and the connector that is more conductive than soldering. 2. The soldering process causes corrosion because even rosin core solder is slightly acidic. 3. The solder that flows into or onto the conductor (wire) causes it to stiffen and increases the probability that vibration or movement will cause the wire to break at that point. 4. The annealing of the copper wire is altered which also increases the possibility of wire breakage due to vibration or movement. It is absolutely necessary that the proper tool be used for the connection being crimped. If you are going to use a crimped connection it is imperative that you have a tool that matches the connector. If you do not have the proper tool then DO NOT use crimped connections.

In-Reply-To: References: Message-ID: Thanks Jim. I will give you my best answer as it related to our Bell System/Bell Telephone Labs tests done prior to our total conversation to crimped and wire wrapped connections. 1. No, soldering doe not create a molecular connection but is (memory suffers here) an amalgam which changes over time as components of the solder leech out. When new the soldered connection has a very slightly higher resistance than the properly crimped connection. 2. Not sure as we did not attempt to remedy a known problem when it could be avoided with no negative results. I suspect the answer is no as the contaminates within the soldered connection will continue to leech out over time. 5 The properly crimped connect has the lowest and most stable resistance over time.

Message-ID: Dave : Thanks for asking this question. As a K2 owner with the KAF2 installed, I have also often wondered what I am missing out on by not having the KDSP2 installed instead. From the responses to your question, the consensus seems to be that it is well worth the upgrade if you primarily operate SSB but maybe not so much if you are primarily a CW operator. I personally really like the KAF2 for CW. On a related note, it occurred to me that the K2 has been in production for almost 20 years ! Wow ! I think that this is a testament to the incredible job that Wayne and Eric did in designing the rig, then working at over the years to continuously improve it. What other Amateur radio can you think of that is still in production after 17 years ? It was an awesome rig in 1998 and it is still an amazing performer for its price today.

I presume you connected the cable to ANT 2 when you selected it? If not, try it. If it is OK on one antenna, take off the cover and check that the antenna connector that doesn't work is plugged into the KAT3 as it should be. Does this happen on all bands? That will tell you if there is a problem in the lowpass filters or the KAT3. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 5 Nov 2015 17:23, WR5DC wrote: > I have a K3 that quit transmitting on SSB last night so I connected an > SWR/Wattmeter/Dummy Load directly to Antenna 1.

For starters the crimper should have compound leverage and a ratchet that prevents you from releasing pressure before the crimp is complete. In addition to that the crimper should have removable dies so that it can be used for multiple crimp connectors. The real catcher is that the die used should be the correct die for the crimp connector itself. The connector itself should also match the wire size used. Sorry that was not a complete answer :) If the crimper does not have compound leverage handles and replaceable dies I would avoid it unless it was purchased for one specific use.

All of the connections are compression type, no solder no crimp, but metal to metal, like copper 0000 cable and brass terminals will brass set screws.? In all of my years, it was common practice to tighten the connections to the correct torque setting, then wait 24 to 48 hours and RE-TORQUE them as the metal under compression relaxes after the initial setting and every time the required torque had to be reset.?

There is only one good *type* of crimper, and that is the racheting type. Some come with changable dies while others are task specific. The crimp connector must be properly sized to the wire, and the die must be sized to the connector body. If the only thing you are going to crimp are Anderson PowerPoles, get the one specifically for that application - but also get the proper size APP contacts for the wire size you will be using. If the wire does not fill the wire cavity, the crimp will not be good and may pull out. Crimping to solid wire is also problematic. If you don't have the right crimper, it is better to solder for most ham applications. Mobile/high vibration applications will do better with crimping, and if you have to solder those for mobile use, support the wire about 2 inches away from the connector to prevent flexing where the solder has wicked up the wire. 73, Don W3FPR On 11/5/2015 12:51 PM, David Cole wrote: > Could someone recommend a good crimper please?

My KPA500 (S/N 2663) Amplifier stopped working in the middle of a CW QSO on 7MHz. It has been working flawlessly for the past two months (since new). At the time: Driver is a K3 running 20w and KPA500 running 400 watts. Antenna tuner is a KAT500. Antenna is a GAP Challenger. Frequency was 7.07 MHz. While transmitting, the SWR on the KPA500 went high and a Fault flashed. The KPA500 seemed to reset its self and I continued sending. The sequence repeated a few seconds later except that the KPA500 had no output power. Further testing resulted in the following findings: Reloaded the firmware. K3, KPA500 and KAT500 was connected in accordance with Figure 1, Page 5, of the Owners manual. For the following tests, the output of the KPA500 was connected directly to the SWR meter and the SWR meter was connected directly to the dummy load eliminating the KAT500. Frequency: 3.57 MHz, All works well. Frequency: 7.07MHz, K3: (ON) 100w, KPA500: (Standby), SWR on KPA500: 1, SWR on SWR meter between KAT500 and dummy load: 1.1:1 K3 power reduced to 10w, Switch the KPA500 to Operate, KPA500 no lights indicating SWR or Power. K3: SWR and RF indicators jumping up and down. Raspy tone heard in station monitor (TS-850). The LCD shows: "7.0 MHZ" no matter which switch around the display I push or how many times I push them or how long I hold the switch. Frequency 14.07 MHz, All works well. The KPA500 (kit) is under warranty, anyone know what s going on here? Did I do something wrong? Is it time to send it back to Elecraft?

All the rest are internal levels [+5/0 I think] and are internal control signals for accessories. The one you mentioned looks like a standard USB-Serial adapter. It also has the Prolific chipset. I haven't had any problems with Prolific but many folks have. The FTDI chipset is recommended by Elecraft. I sold my KPA100 and KAT100 when I went QRP on my K2, but while I had them, I just made a Y-cable from the K2 that split out the 3 RS-232 to one connector and the remainder to another. It wasn't hard. I think that's pretty much what you have to do. Elecraft may sell the Y-cable adapter. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 11/5/2015 3:50 PM, Tom McCulloch wrote: > I know the cable from the K2 to the nine pin plug is not wired in a > "standard" way, but how do I go about interfacing my K2 to the USB port > on my computer? > > I see this on Amazon, but I'm hesitant to try it: From w3fpr at embarqmail.com Thu Nov 5 19:18:56 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 5 Nov 2015 19:18:56 -0500 Subject: [Elecraft] USB for K2 In-Reply-To: <563BEB37.6090406@att.net> References: <563BEB37.6090406@att.net> Message-ID: <563BF1F0.7040606@embarqmail.com> Tom, It has been covered many, many times. All those who have purchased a used K2 and do not have the special K2 to PC special cable, please pay attenion - the health of your K2 may be at stake. Do *not* plug a computer serial cable into that connector. Note that it is labeled "AUX I/O" and that does *not* mean "RS-232" In addition to 3 RS-232 signal lines (TXD, RXD and Signal Ground), it contains internal K2 signals that are used to control the KAT100, XV series tranverters and the KRC2. RS-232 level signals from a computer port can damage those internal K2 signals, or at least cause "strange operation". Download the K2 KIO2 and/or KPA100 manual and build the cable that is shown in those manuals. You will need a length of shielded 4 conductor with ground wire, a male and a female DE-9 connector and 2 backshells to hold the connectors. You can plug that special cable into a computer serial port or connect the PC end of that cable to a USB to serial adapter (use an adapter with an FTDI chipset for best results). 73, Don W3FPR On 11/5/2015 6:50 PM, Tom McCulloch wrote: > Hi gang, > > I think this may have been previously covered, so I apologize if I'm > redundant. > > I know the cable from the K2 to the nine pin plug is not wired in a > "standard" way, but how do I go about interfacing my K2 to the USB > port on my computer? > > I see this on Amazon, but I'm hesitant to try it: > > http://www.amazon.com/dp/B00425S1H8/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=2BU7MNUYG3YU2&coliid=I1591SJBBKODFX > > > Thanks for your help with this, > > Tom, WB2QDG > K2 #1103 > ______________________________________________________________ > 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 mhvnmn at gmail.com Thu Nov 5 19:22:39 2015 From: mhvnmn at gmail.com (Marc Veeneman) Date: Thu, 5 Nov 2015 19:22:39 -0500 Subject: [Elecraft] Looking for Grandkid radio In-Reply-To: References: Message-ID: <1F25A31B-9086-4778-9C47-3E56A1ACDDD0@gmail.com> Code oscillator and key helped my grandson learn Morse 750 miles away from ham Opa.

Saw where someone said that Koss actually makes the CM500 for Yamaha so ordered the SB40 as replacement. First trial was CQ WW SSB a couple of weekends ago.? Rig had been sitting in the closet for several months so brought it out and coupled with Buddipole, 6ft out the window of 24th floor apartment here in HP. Audio reports were terrible including those from guys who knew my voice...I had to 'close talk' the SB40 with mic touching lips....using VOX as could not find the foot switch adaptor for the Heil footswitch. Vox had never been an issue as I have used VOX on the K3 for 7 years with no issues...best Vox I have ever experienced....audio was so bad, one guy suggested to turn down the drive on my amp....I was running barefoot K3/100 @ 90w.? Found CM500 in packing box and got it going....audio became the usual outstanding. So, what is the difference between these two headsets and what can I do to properly use the SB40? BTW, the Buddipole/CM500/K3 combo was great...due to proximity to building, could only use BP on 10 and 15m...worked over 600Qs in 3 hours on 10m on Sunday pm......great fun.

If you are running the SB40 into a sound card, you need a card with 20dB boost on the microphone input. One SB40 reviewer tried to replace the dynamic element with an electret, but he said there was insufficient lead length left after he removed the dynamic element. As a last resort, you can tape pretty much any old electret element to the mic boom and run a separate mic line from the element. Mouser has a good selection of electret elements, many under $5. My CM500 microphone element failed, and I replaced it with an electret element out of an old toy that I found laying around the house. It sounds fine. The SB45 headset has an electret element, but it is not the same comfortable headphone arrangement as the CM-500.

This is important; in evaluating suppliers for our adapters at Pro Audio Engineering we were sent a sample of non-Anderson PP connectors which just did not mate correctly with the real thing. The leaf spring under the contact was of insufficient preload to keep the pair mated under light tension, which also throws the reliability of the contact resistance into question. We didn't find a problem with crimp retention, but that is so very specific to the actual ID of the ferrule and the gauge of the wire being crimped. It is possible that someone using a wire at the small end of the range for that specific contact could have a problem. It can be compelling to save 50% or more on a connector, but we ended up using Anderson PPs, and have had zero quality issues as a result.

I would suggest otherwise. While regenerative receivers are "fun" to play with and can be quite sensitive and selective when properly tuned, they do require some 'training' to know how to properly operate both the tuning and the regen knobs together. If you want to pursue the Regen route, look at some of the regen designs by George Dobbs G3RGV - he has several that work well. Since your grandson likely has access to a computer, I would suggest that you look at some of the SDR receivers, such as the SoftRock kits - inexpensive and quite functional for all modes. Building the kit (with help from grandpa) may peak his interest in building his own gear and add to his interest in the hobby. some software running on the computer is necessary, but there are several software applications that will do - Rocky is one of the easiest to install and configure, HDSDR is good but requires a bit more configuration "smarts". There is also PowerSDR that can be used and there may be more that I am not familiar with. If kit building is not in store, then look for a used receiver/transceiver that may be up to the task. If you can find someone who has an SWL40 transceiver for sale (ask on the QRP-L reflector), that is a good starting point for 40 meters that will give good results - there are versions for other bands as well, but I suggest that 40 meters is the best starting band for single band rigs. There is usually some activity on 40 when other bands are 'dead' - and an antenna for 40 meters is of a reasonable size. I started introducing my 2 grandsons to electronics when they about 8 years old. It only "took" for one of them who got his license at age 13. The 6 granddaughters were not interested at all. So do keep working with him - if it "takes", ham radio in its diverse interests and niche activity groups can produce a lifelong hobby, and may be an introduction to a rewarding career in electronics and/or communications technology. I am one of those examples - I became aware of ham radio in Boy Scouts at the age of 14 when the local ham radio club offered classes in morse code. That led to my novice license at age 15, and those ham club members, coupled with my interest in math, led me to pursue an electrical engineering degree. That led to a very rewarding career and now even though I am officially retired and at age 75 1/2, my workbench is always full (and usually backlogged) with repairs of Elecraft gear. So there is hope for your grandson to engage in a lifelong pursuit that he may really enjoy. If he enjoys puzzles, he may enjoy puzzling over electronics problems which is the heart and soul of troubleshooting (and design). 73, Don W3FPR 73, Don W3FPR On 11/5/2015 6:46 PM, Niel Skousen wrote: > Found out last night that one of grandsons (6 1/2 yr) has developed an interest in Morse code and radios.

If the frequency response is reasonably level and the sensitivity is about the same as other electrets - in other words, if there's nothing "wrong" or "unusual" about it - then the K3 will manage the rest. Over the past 7 years I've had very good results with the Koss CS-100, a lightweight on-ear computer headset with the usual electret microphone. That headset was originally purchased for Skype but was found to work very well indeed with the K3 - not only for my own voice but also for my wife and for guest operators. As a result, these headsets have proliferated around our household and also throughout the radio club. Still preferring closed-cup headphones for my own use, about two years ago I switched to the Koss CM-45. The electret microphone is essentially identical to the CS-100, so operators can freely swap headsets without needing to change any microphone or EQ settings. >The SB45 headset has an electret element, but it is not the same >comfortable headphone arrangement as the CM-500. > Headphone comfort is a very individual thing. I have used the Koss SB-45 for about two years now with no discomfort over many long hours; on the other hand, Heil headphones hurt my ears within ten minutes. The CM-500 I have never tried, as it's not readily available in Europe. So, in what way is the headphone arrangement "different" between the SB45 and the CM-500? 73 from Ian GM3SEK (Please excuse any delayed replies over the next few days - we're having phone-line problems.)

What happens if you turn off the bias? If you get no audio, then it is an electret element, but if you do get audio out of it, it is dynamic. Operating a dynamic microphone with bias turned on will create distortion. 73, Don W3FPR On 11/5/2015 8:40 PM, cx7tt at 4email.net wrote: > > So, what is the difference between these two headsets and what can I do > to properly use the SB40? > > BTW, the Buddipole/CM500/K3 combo was great...due to proximity to > building, could only use BP on 10 and 15m...worked over 600Qs in 3 hours > on 10m on Sunday pm......great fun. > > Suggestions for using the SB40 w/K3? > > From rmcgraw at blomand.net Fri Nov 6 09:48:11 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Fri, 6 Nov 2015 08:48:11 -0600 Subject: [Elecraft] K3 Yamaha CM500 vs Koss SB40 In-Reply-To: <563CBB0A.8040607@embarqmail.com> References: <1446774016.641203.430603657.6CDA4D17@webmail.messagingengine.com> <563CBB0A.8040607@embarqmail.com> Message-ID: <563CBDAB.4000300@blomand.net> As a general rule, if you measure the DC resistance at the connector on the mike and it is less than 2K ohms, it is likely dynamic. If it is 10K or more, it is likely an electret element. If it is near infinity then likely there is a DC blocking capacitor in the circuit. The R values have nothing to do with impedance, as they are just DC resistance values. The electret element requires bias. They dynamic will likely distort when bias is turned on. 73 Bob, K4TAX From ae4pb at carolinaheli.com Fri Nov 6 09:56:25 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Fri, 6 Nov 2015 09:56:25 -0500 Subject: [Elecraft] having problems connecting my K-3 to Ham Radio Deluxe In-Reply-To: <563CB9BB.70704@blomand.net> References: <563CB9BB.70704@blomand.net> Message-ID: <017601d118a3$508e1640$f1aa42c0$@carolinaheli.com> What issues are you experiencing?

Don's suggestion about finding an SDR makes lots of sense. Add a key and oscillator so he can make noise but not transmit and away he goes. The goal of a quality receiver, that is simple to operate makes sense.

I was around Niel's grandson's age when my dad took me to his workbench in the attic. I came away with a homebrew crystal set which I built under his tutelage. It would only pick up the two local BC stations, but it worked. (I did eventually get to have his old Hallicrafters RX in my room for a while.) My homebrewing and kitbuilding continued later on from there with items like a Heathkit portable AM receiver (which I still have) and on to more recent kit offerings including Elecraft. My experience with today's web/smartphone focused kids is that any mention of communicating by radio with someone on the other side of the world is met with glazed eyes.

You may find a change in a firmware upgrade coming soon, but I don't know when. 73, Don W3FPR On 11/6/2015 12:05 PM, ok1rp wrote: > Hi all, > > few days ago I realized on K3 (using latest MCU/FPF) weird receive audio > dropout problem. > It happends during QSK CW operation and it is hearable in audio in between > TX periods > time to time but it is repeatable.

This issue is strictly on 12M, 10M and 6M. Even noticed on 10M and 6M AM with the artifact being a momentary carrier collapse. It's fast, about 10 milliseconds and does occur every 15 seconds. I tried a bug with my K3S and did not find to have reliable keying. I cleaned the bug contacts but to no avail. Went back to the Iambic paddles and the internal keyer with 100% satisfaction. 73 Bob, K4TAX On 11/6/2015 2:06 PM, Steve Ellington wrote: > K3S....QSK on any band, CW...I hear an occasional clunk or pop but only > when using the bug.

With my McElroy stream I had to add a 1uf capacitor in parallel with it. After reducing the dit gap to compensate to the keying, it sounds great. On my Vibroplex Presentation, no capacitor is needed and keying is perfect. I noticed the same thing on my old K3 and a few other rigs. I suspect it's something to do with contact bounce due to variations in the dit spring and how different rigs react to the bounce. I have to remember we are no longer just keying a circuit rather we are keying a computer from another planet. :*) Steve N4LQ On Fri, Nov 6, 2015 at 4:04 PM, Bob McGraw - K4TAX wrote: > Steve, I believe anything else you are hearing is something else.

Once again doing something worth-while with a soldering iron in your hands.!! The result: Amazing,? and yet I fell for the KDSP2 noise reduction on SSB signals as demonstrated on the home page of Elecraft. Having concluded and installed the KDSP2 I learned that it takes some time to get into the deeper intricasies of this add-on module. A friendly US amateur told me over a couple of mails: ?You will love it when you learn to master it. But when you do, it does work wonders.? He was right, but it does take willpower to remember what you were doing last time you changed something. The reason for the operational difficulties is, that the set-up of bandwith, filters and other specifics can only be reached in the second or third level of pushbutton strikes. After a thorough study of the manual it clear to you, but after a month?. Alas !!

These are only about 3 db variations however. Setting the speaker on the desktop makes a *HUGE difference* in loudness...Maybe 10 db or so. The reflection from the surface helps greatly and this is true of most speakers. Setting it on a shelf totally wrecks everything.

What OK1RP may be hearing is the ATU switching its relays when he first transmits in a band segment that requires new LC settings. The firmware attempts to do that between CW elements (in RX mode). This should be extremely rare. (If it's happening more frequently, it could be related to particular combination of AGC and QSK menu settings along with high QRM/QRN on a given frequency. I would try selecting "OLD QSK" or "NEW QSK" to see if that has any impact, and/or increase the AGC THR value.) The PA temperature anomaly reported earlier should also be extremely rare, and in fact no one had even mentioned it in years. Nothing has changed in this firmware recently. But I'm working on a firmware improvement for that and will discuss it later after testing.

Message-ID: <563D765C.23164.7277C07@Gary.ka1j.com> I must have hit something inadvertently because my P3 is exhibiting a new behaviour I haven't experienced before; Lets say I'm on 80M and switch to 160M. The K3 is now on 160M, the digital markers on the P3 show 160M frequencies. I tap the marker A button to highlight Green, I adjust it to a desired signal & when I push the control knob, it puts me back to 80 meters or at least to a different band. Whatever the cause, I have had it happen repeatedly lately, not every time but often enough I've become wary of where the P3 will send me. Since this is a new behaviour, it's either the result of my having changed a setting or something to do maybe with a recent firmware update?

K2 is a QRP radio SN 01392. This happened to me two times today. Occasionally when I come down into the shack and turn on the K2 I will tune around for a few minutes looking for anyone calling CQ. When I hear a station I will send my call sign. When I go to give the usual RST, name and QTH the VFO will drift up. The weird thing is that I can clear the problem by turning off the radio, wait 10 seconds, and then turn it back on. The VFO is stable and will not drift while I transmit. Today when I saw the rig drifting again I placed the rig on the dummy load. It will continue to drift until I turn it off and wait 10 seconds then turn it back on. Like I said it does not happen all the time. 73 Ron Polityka WB3AAL From indians at xsmail.com Sat Nov 7 06:42:05 2015 From: indians at xsmail.com (Petr Ourednik) Date: Sat, 07 Nov 2015 12:42:05 +0100 Subject: [Elecraft] K3 QSK CW Audio Dropouts In-Reply-To: <3A0863BE-B171-4B24-B452-BBABF9CAB3AE@elecraft.com> References: <1446829507154-7610047.post@n2.nabble.com> <563CE720.6090909@embarqmail.com> <3A0863BE-B171-4B24-B452-BBABF9CAB3AE@elecraft.com> Message-ID: <1446896525.1437356.431763537.60D016EA@webmail.messagingengine.com> Hi Wayne, Many thanks!

Is there some drag on the VFO tuning knob? If the knob is "free-wheeling", it can drift from its position easily. It may be that a solder connection in the PLL Reference Oscillator, or the BFO or the VFO has developed some oxidation over the years. Reflow the soldering in those areas. To identify the components, look at the RF Board schematic sheet 1 - everything on the top of that sheet has to do with the PLL and VFO. The BFO is on the lower right corner of sheet 2. 73, Don W3FPR On 11/7/2015 6:17 AM, WB3AAL wrote: > This happened to me two times today.

For many years I have been using an amplified "one to three splitter". It is stereo with a male input and three female outputs. The circuit appears to be six emitter followers, two for each output, so there is isolation with power gain but no voltage gain. It is powered by two AA cells that seem to last forever but I only use the splitter when using the K3 and have a guest in the shack and we are putting on the cans to keep other members of the household happy. I understand you wanted male outputs but that is easily converted by plugging in male to male cables. I got the first one from the manufacturer and latter picked up 3 more when RS was closing them out. I have since seen them advertised by other online sellers. Would this solve your problem? 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Joel Black Sent: Saturday, November 7, 2015 5:53 AM To: Elecraft Reflector Reflector Subject: [Elecraft] [OT] Headphone Splitter - Not The Kind You May Be Thinking I am looking for a stereo headphone splitter - with a caveat?

In DXLab Suite, in the WinWarbler Config window under the CW tab select "Xcvr Ctrl App" as the Keying method. Commander must be running. WinWarbler will direct Commander to use radio control commands to send CW. There is a way to force N1MM+ to use the method used by DXLab suite, by using user-programmed radio control macro commands, but this is a clumsy kluge that disables some of N1MM+'s features, as described in the on-line N1MM+ documentation. With a K3 or K3S (as distinct from a KX3), there is a better alternative that supports the full range of features in N1MM+, namely the one that is described in the next paragraph. In N1MM+, check the CW/Other check box beside the COM port number you are using for radio control, click on the Set button, and set DTR to CW. On the K3/K3S, set CONFIG:PTT-KEY to OFF-DTR. This is for VOX/QSK operation; if you want to have the computer control PTT, in the N1MM+ configuration set RTS to PTT, and on the K3/K3S set CONFIG:PTT-KEY to RTS-DTR. DXLab Suite cannot use the method used in N1MM+ because it does CW and radio control from two different programs that cannot share a single serial port. 73, Rich VE3KI K9OM wrote: > Using only the USB Port cable to the CPU, can CW be transmitted on the K3S > using N1MM Logger+ or DX-Lab software without the use of a WinKey?

The good stuff is made by Switchcraft and Neutrik, and can be bought from vendors like Full Compass (Madison, WI) and Sweetwater (Ft Wayne, In). You can find part numbers on one of the later slides in my Power, Grounding, and Audio tutorial. k9yc.com/publish.htm One of the tricky parts of making Y-cables is finding cable that's small enough to fit into connectors, yet rugged enough to withstand flexing, and connectors into which the cables can be fit. Switchcraft have the greatest diameter for cable entry and the most space inside the connector shell. 73, Jim K9YC 73, Jim K9YC 73, Jim K9YC From jbollit at outlook.com Sat Nov 7 12:20:54 2015 From: jbollit at outlook.com (jim) Date: Sat, 7 Nov 2015 09:20:54 -0800 Subject: [Elecraft] Grrrrr!

The rig I am using is a K3 with the new Synth boards and general coverage band pass boards. I have the KXV3 set to "test". That turns on the transverter in/out which I use for rx and tx. The tx out gives me about -30 dBm. I then use two Minicircuits ZHL-32 amps with some attenuation to get to +8 dBm. That drives the Hafler P3000 amp to about 200 watts out. Output on 630 meters from the K3 is about 1.5 dBm, so not much amplification to get some decent drive. The K3 dynamic range really comes into play on 630. I have WH2XXC about 12 miles from me. He is + 25 db as reported by WSPR, yet I can still decode stations during his transmit segment that are -25 db as reported by WSPR. Gotta love that K3. Take care.

Also use the same cable for my "stomp to talk" switch on the floor. I've also used the RG-74 cable for the EXT Speaker output from the radio to the two speakers sitting beside the radio.

Message-ID: I am wanting to connect a computer headset to my K2. I bought the K2 used along with an Icom HM-12 hand mic that I have used successfully. I haven't opened the radio up to see what the bias resistor is inside of the K2, but I measure +5V between pin 1 and pins 7 and 8 of the microphone connector. I believe that means that a bias resistor has been connected internally to put the bias voltage that the HM-12 needs on pin 1. (As a sidenote, trying to measure the bias on pin 6 with my DMM appears to reboot the microprocessor, sending the LCD screen back to "ELECRAFT"!!) I am not sure about the bias needs of the headset that I have, which I intend to use for infrequent SSB contesting. Following a recent message on this reflector, I measured the resistance from tip to sleeve of the microphone plug at 830 ohms. That message suggested that such a low resistance would be indicative of a dynamic microphone element. The headset works fine with Skype on a laptop if that means anything. I've got a mic plug and a female inline 1/8 socket and I will be making an adapter for the headset. I want to be able to change from the hand microphone to the headset without making internal changes on the K2, of course. Ideally, I would like to use the same 1/8 inch to 8-pin adapter for soundcard digital modes with the K2. What should I do about the bias on microphone pin 1? Should I just use the headset as-is, risking distorted audio with a dynamic microphone fed 5 volts of bias? Should I include a blocking capacitor (of what value?) in the adapter that I build? Thanks in advance for any advice you can offer. -Neil N0FN From joel.b.black at gmail.com Sat Nov 7 15:05:47 2015 From: joel.b.black at gmail.com (Joel Black) Date: Sat, 7 Nov 2015 14:05:47 -0600 Subject: [Elecraft] [OT] Headphone Splitter - Not The Kind You May Be Thinking In-Reply-To: References: Message-ID: <0F19B2A3-F254-4E34-AD51-CA635FEACBFA@gmail.com> Thanks for all the suggestions.

In using a "hard wire" type of Y cable, for your application, you will end up connecting the audio output of the K3 to the audio output of the KX3 through the Y cable. I doubt that one radio will like driving the output stage of another radio and could damage one or both radios. You will need some form of isolation system or amplification. I suggest a small inexpensive mixing amplifier for the job. For my application I use a Behringer UB 802. The line level or aux output from each radio connects to a separate input of the mixer. The headphones connect to the internal mixer headphone amp. I can then control the level from each radio to the headphones and the headphone overall level. As to using a Y cable to connect one CW key to two radios, you will be likely keying both radios at the same time, unless you take steps to have one radio off and one radio on. Again, a Y connector is not the correct way to handle this method. Better is to use a box that will switch the output of each radio to the headphones making sure that only one radio at a time can be selected. This also applies the the CW key. Someone recently suggested using a two port printer switch, the one which has the 25 pin connectors on the rear. These are also known as an A/B switch. Even then you will have a good bit of wiring to accomplish. Lazy is not the proper term. Doing it correct is the proper method and a Y connector isn't it. 73 Bob, K4TAX On 11/7/2015 2:05 PM, Joel Black wrote: > The reason for wanting them is so I only have to use one set of headphones and CW key between my K3 and KX3.

It is time for new radios with the upgraded synthesizer and USB connections. They are all K3-100's equipped with: KRX3F Subreceiver KVX3A RX Antenna Module KFLA 500 in both receivers KFL3A 1.8K in the main receiver Serial Numbers are 3463, 3464, 4391, 4498. All have systematically been back to Elecraft and have the important upgrades installed. They are all in excellent working order with just a few cosmetic issues. They are offered at $2,900 each with the original boxes, including FedEx Home Delivery. A similarly equipped K3S is $4,150. This would be a time-phased sale. Obviously, we will have to sell three K3's to buy two K3S. Elecraft is quoting 3-5 day delivery for the K3S and we would have to schedule the change outs around major contests. S/N 3464 is in the box, just having been repaired at Elecraft. It is immediately available. No trades. No haggling. W7RN is a not for profit foundation subject to a chain of approvals.

I went ahead and rewired the T-UG8 base back to the original schematic to ensure that it was as "stock" as could be. I also noticed that the original crystal element (under the insulating material) looked like someone pushed it in some (and it had a small pinhole). I decoupled it and replaced it with a Shure 99E86 element that I had lying about. On the radio side of things, I went through the KSB2 alignment procedures, just to be sure. SSBA is set to a 3, SSBC is set to 2:1 (at least I think that's right.. the manual and radio is in the garage). Last but not least, I also turned the D104 5K pot to a hair above its bottom extremity. Now blowing or whistling or just plain talking into the mic will cause the K2 to cut out with a slight bzzt*pop* [from the radio] as the s-meter goes all the way to the right and then goes dark. This happens every time. That said, that Shure element is medium impedance as far as I know, about 300 ohms IIRC. At that point, can I (or should I?) completely bypass that preamp? Can anyone provide an example schematic on the routing without the preamp? Is it safe to just use the schematic from the unamplified UG8 base?

A better solution would be some of the specialty miniature shielded twisted pair cable that companies like Belden make for portable use with microphones. It IS possible to shoehorn two of them into a Switchcraft plug. BUT -- Bob, K4TAX is right about it being a really bad idea to tie output stages together. While they are probably protected by series resistance (good designers do that so when folks do dumb stuff the output stages don't fry), the resistance will also lose a lot of signal. I do NOT recommend Behringer products -- in the pro audio world they have earned a really bad reputation for lousy build quality, poor support, and ethics. The good brands (and companies) making good stuff for this kind of application are Rane, Mackie, and Radio Design Labs (RDL). Look for their products on their websites, then chase down used items on the usual places. 73, Jim K9YC On Sun,11/8/2015 10:18 AM, Ron D'Eau Claire wrote: > As others pointed out RG-174 has only one internal conductor.

Although is rarely happens here - most days it does not happen at all - but once in a while it does happen repeatedly. When it happens I think it is due to some kind of occasional interference on the 2,4 GHz WiFi. However, it is very interesting that whenever my KPA- and KAT Remote Clients disconnect, the same thing normally (not always) happens to the HRD Remote Client *but never* to the Winkey Remote Client. If some Server/Client programs are more robust than others I would rather see the not-so-robust ones be made more robust than solving the problem by incorporating an automatic reconnect. Can others confirm my observations - and if so can someone here explain why the WK Server/Client is more robust than KPA/KAT and HRD Server/Client? 73/Poul-Erik OZ4UN -----Oprindelig meddelelse----- Fra: Elecraft [mailto:elecraft-bounces at mailman.qth.net] P? vegne af Rick Tavan N6XI Sendt: 8. november 2015 23:59 Til: Elecraft Reflector Emne: [Elecraft] WBN: KPAxxx Remote Automatic Reconnect Both KPA500 Remote Client and KAT500 Remote Client have a tendency to lose connection to their respective servers here at N6XI and have to be commanded manually to reconnect.

There's several wiring diagrams on the internet, find one and wire the base accordingly.

If you are using the original D-104 element, then the preamp is necessary in order for the mike element to see a proper impedance and the preamp will drive a lower impedance such as found in today's radios.

To: Bob McGraw - K4TAX G'mornin Bob, The cord on the base is only four wires: black, red, white and shield. Note this is a T-UG8 base.. I think the UG8 was the unamplified base? I don't know if either had a cord with more than the four wires; I know my T-UG9 base does. Internal to the base itself there is a blue wire, as detailed in http://www.rollanet.org/~rrars/tech_files/d104_manual.pdf. That is exactly how the mic is wired now. The only thing I did not rewire is the leaf switches as they appeared unmolested. I will take a look at those tonight as I wanted to check their contacts anyway. In the old electromechanical pinball machines, those things would oxidize fairly quickly, so I thought it would be good to check here anyway. I will also give it a whirl with a dummy load. I only have the small dummy load kit from Elecraft... I assume that will be okay? I'll also take a look at bypassing or just flat out removing the preamp circuit.

AFSK works just fine. I have ran many RTTY contests with the K3 in FSK mode, using various software drivers. The problem is I get a single tone, but at the wrong frequency, Its about 200hz, not 2125Hz. I checked the pitch setting, its still setup for High tones, the radio keys just fine, I have not checked the fsk input signal, but even if that was bad and not toggling I should still have an output at the Mark frequency, not way low at ~200hz. I reloaded firmware, - no change. The K3 is a mid 5000 serial number and has worked flawless for many years of RTTY contests. This one has me baffled, any suggestions? (I switched to AFSK setup for now).

In-Reply-To: References: Message-ID: <5640A930.8010706@david-woolley.me.uk> Out of the box all pins on the microphone connector are open circuit. There is an internal jumper block that has bias free microphone audio and resistor free 5 volts on it. If you are seeing 5 volts on pin one on the external connector it is because someone has wired 5v to it. There may or may not be a load resistor on that, although if pin 1 is audio, one would expect there to be one. The jumpers are designed to be hardwired, but it is just possible to use an IDC connector as a pluggable jumper and there is a third party product, currently out of production, that provides plug in, configurable jumper blocks. If the connector is wired properly, other than the bias, you want to unsolder the bias resistor from the jumpers. It is unusual to find dynamic microphones on PCs, but if you do, they will normally have a mono plug. The normal PC microphone socket feeds bias to ring and audio to tip. If you plug in a dynamic microphone, bias is harmlessly shorted. If you plug in an electret, the microphone has tip and ring connected together internally. If you have a stereo plug on the microphone, I wonder if you have actually measured the substrate diode forward voltage, rather than any resistance. -- David Woolley Owner K2 06123 On 07/11/15 20:03, Neil Martinsen-Burrell wrote: > I am wanting to connect a computer headset to my K2.

This is important; in evaluating suppliers for our adapters at Pro Audio Engineering we were sent a sample of non-Anderson PP connectors which just did not mate correctly with the real thing. The leaf spring under the contact was of insufficient preload to keep the pair mated under light tension, which also throws the reliability of the contact resistance into question. We didn't find a problem with crimp retention, but that is so very specific to the actual ID of the ferrule and the gauge of the wire being crimped. It is possible that someone using a wire at the small end of the range for that specific contact could have a problem. It can be compelling to save 50% or more on a connector, but we ended up using Anderson PPs, and have had zero quality issues as a result.

The mark output from the radio is at RF, not at either 2 kHz or 200 Hz. Do you mean the audio monitor tone you hear from the K3, or are you monitoring in some other way? In FSK D (and also in AFSK A), the K3's dial displays the actual Mark frequency as transmitted. If you are monitoring via an external receiver, the two RTTY frequencies should be at the K3's dial frequency (mark) and at a frequency 170 Hz lower (space). The audio monitor tone from the K3 should be at the K3's Pitch setting. If it isn't, that would seem to point to something odd in the monitor, which does not necessarily mean there is anything wrong with the actual transmitted RF. 73, Rich VE3KI N1MGO wrote: > I normally use MMTTY, with DXLabs.

I get tripped up on this every once in a while. If these settings are correct you probably have a physical problem with the FSK keying lead between the interface and the K3. You can check the radio by grounding pin 1 of the ACC (DB15) connector. The tone will shift when grounded.

There is a BAT MIN menu item where you can specify the voltage below which that message will be blinked on the display periodically. It has a default value of 11 volts - check yours to see what it is actually set at. That feature is nice when you are working with a battery because you can see when the battery needs to be recharged. With a good power supply in use, if you see that message, it would be an indication that you should check your power supply and the PS wiring to the K3 for possible loose connections. For the remote operation questions, someone other than myself will have to answer, I have no experience with that. Brandon at Elecraft is quite knowledgeable and may be able to help along with the support folks at RemoteRig. 73, Don W3FPR On 11/9/2015 1:27 PM, cx7tt at 4email.net wrote: > > Went to the K3 manual and there is nothing about a battery in the Index. > Nabbled K3 battery and yes, there is a battery.

I got the system working. The problem was the pitch setting. While in FSK D If you hold the Pitch button the K3 shows the current pitch, (2125-170) is what was showing. I changed it to low tones (915-170) and back to 2125. That fixed it! I now have working FSK-D mode again. I'm not sure what was going on, but the pitch was at some value of ~200hz, not 2125. Resetting the pitch fixed it. So for future reference, don't believe the display, change it and then set it back to what you want!! I was hearing a tone of about 200 hz when going into tx, but was hearing the 2125 when I pressed the Pitch button. Now I hear a tone of 2125 and diddles when I use the software to send something.

The virtual ports seem to come from the RR box. On my computer [Win 7], the Device Mgr says the ports are there but they really aren't ... they're just reserved for when the computer and RR are connected via the USB. If the USB isn't connected, N1MM+ can't find the RR ports N1MM+ seems to want the CAT port to be RR1258 COM1 which on mine ends up being COM15.

What does impress me is the absolute quality of the received signals presented to my ears by the K3. In about 55 years, my K3 is the most satisfying receiver I have ever used - and I have had most of them along the way. Fed to my outboard speakers, it sure makes for some super arm chair rag chews. All I have to do to prove same, is to switch to one of my other rigs. Then get on 75 meters at 7:30 PM and have some group move in right beside you.

Too many for discussion here. However two thoughts. In general the faster the processor the 'more' chances of producing RFI. It could be Wayne and the boys kept the processor speed low to reduce noise. Also in CMOS processors the current drain goes up proportional to the square of clock frequency. Simply faster processors take more power and with power comes the need for fans and heatsinks. That's from the physical side. However the application of more filters could possibly reduce noise from the software side but this is far from a simple tradeoff.

The stuff's a real bargain, and the twisted pair construction makes it a great choice around RF. I picked up a 100 meter spool in eBay for around $30. I either don't use the spare pairs or double 'em up, depending on the capacity of the connector terminals. I use mostly Rean connectors, available from Mouser, for my audio cables. They're good quality and you can get shells that take larger diameter cable if needed for the 1/4" and 3.5mm plugs. 73...

What does impress me is the absolute quality of the received signals presented to my ears by the K3. In about 55 years, my K3 is the most satisfying receiver I have ever used - and I have had most of them along the way. Fed to my outboard speakers, it sure makes for some super arm chair rag chews. All I have to do to prove same, is to switch to one of my other rigs. Then get on 75 meters at 7:30 PM and have some group move in right beside you.

Comments from those that don't seem to have a use-case for NR aren't really applicable to this particular topic, either. Personally, I find the NR capabilities of the KX3 to be among the best and most flexible that I've ever experienced, but also find the K3's capabilities to be fairly anemic in comparison. I would love to see the KX3's approach implemented in the K3 - that would make for a VERY nice upgrade, IMO.

CW will be the primary mode. Many will run beacons while listening between transmissions for callers. There should be a fair amount of QSO activity. Within the past week or so I have had aural CW QSOs with stations in OR and WA from WPA, conditions were less than optimal. Last year several of us also passed NTS formatted traffic. There will also be a few VEs calling CQ and listening for Amateur stations on 40/80 meters. See details in full announcement copied below. If you do hear any stations on 630M this coming weekend, the operators very much appreciate Emailed reports. This weekend's "event" will probably be the most concentrated Amateur-like activity for the current lowband "season" on 630M. I will be running a K3 w/ transverter (dual channel RX for diversity) driving a modified SB-1000 for 500-1000W output to a 67 ft toploaded vertical over 22,000 ft radials.

This event marks the 107th anniversary of the Berlin Treaty that created the international distress frequency at 500 kHz. This event includes US experimental stations, Canadian amateur stations, and (we hope) US heritage maritime stations. US EXPERIMENTAL STATIONS For US experimental ops, this will be a CW event and the main activities will be: - Some stations will run beacons with special messages, and some will offer special QSLs. - Other stations will simulation maritime communication. They will call CQ on a designated calling frequency and then QSY to complete the QSO. Silent periods will be observed. - Some stations will pass message traffic. - The frequency bands are 465 to 480 kHz and 495 to 510 kHz. Different licensees have different frequency authorizations. - The designated calling frequencies are 475 kHz for the lower band 500 kHz for the upper band. MARITIME RADIO HISTORICAL SOCIETY The Maritime Radio Historical Society (MRHS) will conduct a mini "Night of Nights" on Saturday night, with special attention to MF operations. This will give listeners the best chance of copying their MF signals by operating during the winter and extending our operating hours well into the evening hours Pacific time. KPH will keep 500 kc and 426 kc (and HF) active with special messages, press and weather. And they will send a verification to any listeners who mail in a reception report. CANADIANS AMATEUR STATIONS Five Canadian amateurs will be operating in the 472 - 429 kHz band. In addition to activities similar to those of the US experimental stations, the Canadian amateurs will conduct cross-band communication tests with amateurs operating on 80 and 40 meters. The plans include: Station: VO1NA (Joe) GN37 Torbay, Newfoundland Time: 2130Z - 0130Z both Friday night (Nov 13-14Z) / Saturday night (Nov 14-15Z) TX Frequency: 477.7 kHz RX (QSX) Frequency: 3562 kHz Station: VE7SL (Steve) CN88 Mayne Island, B.C. Time: 0200Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z) TX Frequency: 473.0 kHz RX (QSX) Frequency: 3566 / 7066 kHz Station: VE7BDQ (John) CN89 Delta, B.C. Time: 0430Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z) TX Frequency: 474.0 kHz RX (QSX) Frequency: 3536 kHz Station: VA7MM (Mark) CN89 Coquitlam, B.C. Time: 0500Z - 0700Z Friday (Nov 14Z) 0400Z - 0800Z Saturday (Nov 15Z) TX Frequency: 475.0 kHz RX (QSX) Frequency: 3570 kHz Station: VE7CNF (Toby) CN89 Burnaby, B.C. Time: 0300Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z) TX Frequency: 476.0 kHz RX (QSX) Frequency: 3558 kHz / 7062 kHz All stations will either call CQ or run "VVV" marker beacons while listening on their respective QSX frequencies. QSX frequencies will be included in the CQ or marker beacon. TIME PERIODS The official time period is 00:00 Z on Nov. 14 through 23:59 Z on Nov. 15. These include Friday and Saturday evenings in North America. Stations on the east coast may start a little earlier if they like.

Just like in school.. Show your work. You say that radio has better than the K3/K3S with latest hardware/firmware. Please provide the data upon which you base this. What you hear /think you hear is not valid data because operator skill comes into play. I'm no expert but have played with the K3S long enough to know the power of it's NR is in finding the balance of settings to pull the desired signal out of the noise. Any system that only has a button for NR and lacks granular control of the parameters can't possibly pull signals out under all circumstances when compared to a system that allows for granular control. Opinions aside.. please provide the data upon which your claims are based. Claims without data are just opinion based on several factors; many of which are out of the operators control and change over time. No KoolAid, just facts. I don't know that the K3S is better. On paper a receiver system is dealing with component noise, board noise, power noise, dynamic range, overhead, sensitivity, gain..etc.. On my K3S when digging out signals I'm playing with RF gain, Roofing filters, IF DSP Filtering, AGC Slope, AGC Threshold, AGC Time, and finally NR DSP algorithm (of which the K3S has LOTS). I have 2 main NR settings: One when I expect to have strong local signals (e.g... contests) and one for normal use. When chasing weak signal DX I'll play with settings to see what I can do. You're lucky to have never had to send your Kenwood radio in for repair. You typically end up sending it to a third party repair shop with the hopes they know what they are doing and do more good than harm.

I used the +12V from the sequencer power supply, but you could use the +12V available at the RCA connector on the back of the radio to supply the necessary voltage. GL. 73, Rich - K1HTV = = = I am trying to use the Tx Inh (pin 7 of ACC) to allow the K3 to xmit only when my 2M EME sequencer allows. In testing out this function, I find that when Inh Hi or Lo is used, once you apply a logic change to pin 7 the Tx Inh will lock in the on position. Removing the logic signal, or returning to Rx leaves this function not active to allow for Tx. So Tx inh works fie but for only ONE time? I can re state the Tx Inh only if I go to config and cycle througe the states again. Am I not understanding the function of Tx Inh, or is there a problem in the K3 internal logic?

OTOH, a ham friend of mine a long time ago briefly lived in a trailer park while he was going through some marital difficulties. He had his Swan 350 set up there. A next trailer neighbor of his liked to listen to a rock FM station at high volume fairly early in the morning. My friend told me that he'd noticed a "swish" from the neighbor's stereo on a certain frequency when tuning across 15M. One morning he got tired of the neighbor's concert, turned on the Swan, moved down the band a ways and loaded it "full tilt", carefully zero beat the suspect frequency, keyed the mic, and yelled "bleaah" or some such into it. (He claimed he could hear himself coming through the neighbor's stereo.) The rock station volume immediately went down and he never heard it turned back up the rest of the time he lived there. Maybe Elecraft needs to do some research to see if there are some frequencies where the KPA500 would be effective in this way against nearby teen house parties ;-) However, I doubt it would be effective against earthquakes though.... 73, Al On Mon November 9 2015 9:09:24 pm Wayne Burdick wrote: > Steve Ellington wrote: > > The IC-7851 consumes *200 Watts in RECEIVE mode!* > > So it can dampen shaking due to earthquakes and nearby teen house parties. > > > The K3.....About 12 watts. > > So you can run it from a solar panel after the aforementioned disasters. > > Wayne > N6KR > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to wb5jnc at centurytel.net From Hamshack at N4ST.com Tue Nov 10 10:00:02 2015 From: Hamshack at N4ST.com (Jim - N4ST) Date: Tue, 10 Nov 2015 10:00:02 -0500 Subject: [Elecraft] K3S 40M Sensitivity Message-ID: <003101d11bc8$7eaea940$7c0bfbc0$@N4ST.com> So, I am a very casual participant in CW SS, usually just enough to get the participation pin. This was going to be interesting using my 2 week old K3S in the contest. I knew there had been some geomagnetic storming and even though the flux was high, I thought conditions could be iffy. As the Sun went down, I dropped down to 40M and was surprised that there wasn't much going on. In fact, there wasn't even a lot of atmospheric or manmade noise present. Checked the ATTN. Nope, it was off. RF Gain was at maximum and even tried Preamp 1, but it didn't seem to make much difference. My dipole was OK, because on my external power meter, power was going up the coax and not coming back. Just weird conditions I guess, but very slow going on 40M. Only made about 10 contacts in 40 minutes. Dropped on down to 80M and finished my contest effort that night. Next day, I decide to troubleshoot the 40M problem. Doh! 40M was set up to receive on the RX only antenna, and I don't have one connected. Glad it was an easy fix. Still made some 40M contacts, with no receive antenna! __________ 73, Jim - N4ST From n1rj at roadrunner.com Tue Nov 10 10:14:32 2015 From: n1rj at roadrunner.com (Roger D Johnson) Date: Tue, 10 Nov 2015 10:14:32 -0500 Subject: [Elecraft] APF Message-ID: <564209D8.5090008@roadrunner.com> Whatever happened to the plan to provide adjustable or stepped values of selectivity for the APF function?

The audio is great and radio control via Nick?s (N3WG) software is very stable. I use an Apple Mac mini and/or an iPad as the remote devices and also find that RumLog talks directly to the PigRemote via Serial over IP from either the local network or from any remote location via the Internet. I am under the impression that there are few differences between the the K3, K3s or KX3 as regards the PigRemote.

The design keys being S/N ratio, dynamic range, and gain. Any solution to remove hiss without consideration to S/N ratio and gain results in loss of signal level. Hard to complain about weak signal work if the system is degraded by mods/adjustments. 2. By default the K3S receive audio isn't optimal for everyone's ears and dynamic range. That's likely why there's an audio equalizer for both receive and transmit audio. If you've not adjusted that to optimize the audio to your tastes then you're missing out. I have different hearing issues in each ear. My wish is to be able to adjust left /right audio independently with both a single receiver and with the sub installed. I currently run with AFX on full delay. I usually hear signals on my right ear not my left unless I adjust the equalizer. My right ear being more sensitive than my left. Show me an audio circuit with no hiss and I'll show you missing signal level. For most audio applications this doesn't matter because there's ample signal. When working weak signal it's all about balance and working the edges. If you operate with all knobs cranked to the right I'd humbly and respectfully suggest that you review your operating procedures regardless of the radio you use. Kenwood makes a good radio, however, I've NEVER had good luck with service from them or Yaesu. Based on my experiences in forums, reflector, and talking with other hams; Elecraft is rabidly good about support.

I have a K3, KX3 and TS-590. It's well documented that the nr in the K3 is poor and leave a lot to be desired. Also, in an effort to fix it by making it more adjustable, Elecraft overcomplicated its implementation. I love Elecraft products, but also love the simplicity and effectiveness of nr implementation in the TS-590 (in my opinion even better than the one in KX3). Regarding warranty and service, I totally agree Elecraft is hand down #1 in this area. However, Kenwood just fixed the ALC issue in my TS-590 free of charge after 4 years. The question is, can I send my 3 yrs old (early production) KX3 to Elecraft to get all the latest corrections/improvements (e.g. tuning noise) free of charge. After all, I paid about the same amount of money that someone is paying today for a better product. ;) I'm a big fan of Elecraft, but resist drinking the Kool aid in order to encourage competition.

Hard to complain about weak signal work if the system is degraded by mods/adjustments. 2. By default the K3S receive audio isn't optimal for everyone's ears and dynamic range. That's likely why there's an audio equalizer for both receive and transmit audio. If you've not adjusted that to optimize the audio to your tastes then you're missing out. I have different hearing issues in each ear. My wish is to be able to adjust left /right audio independently with both a single receiver and with the sub installed. I currently run with AFX on full delay. I usually hear signals on my right ear not my left unless I adjust the equalizer. My right ear being more sensitive than my left. Show me an audio circuit with no hiss and I'll show you missing signal level. For most audio applications this doesn't matter because there's ample signal. When working weak signal it's all about balance and working the edges. If you operate with all knobs cranked to the right I'd humbly and respectfully suggest that you review your operating procedures regardless of the radio you use. Kenwood makes a good radio, however, I've NEVER had good luck with service from them or Yaesu. Based on my experiences in forums, reflector, and talking with other hams; Elecraft is rabidly good about support.

Here's a non-KookAid question for you. Just like in school.. Show your work. You say that radio has better than the K3/K3S with latest hardware/firmware. Please provide the data upon which you base this. What you hear /think you hear is not valid data because operator skill comes into play. I'm no expert but have played with the K3S long enough to know the power of it's NR is in finding the balance of settings to pull the desired signal out of the noise. Any system that only has a button for NR and lacks granular control of the parameters can't possibly pull signals out under all circumstances when compared to a system that allows for granular control. Opinions aside.. please provide the data upon which your claims are based. Claims without data are just opinion based on several factors; many of which are out of the operators control and change over time. No KoolAid, just facts. I don't know that the K3S is better. On paper a receiver system is dealing with component noise, board noise, power noise, dynamic range, overhead, sensitivity, gain..etc.. On my K3S when digging out signals I'm playing with RF gain, Roofing filters, IF DSP Filtering, AGC Slope, AGC Threshold, AGC Time, and finally NR DSP algorithm (of which the K3S has LOTS). I have 2 main NR settings: One when I expect to have strong local signals (e.g... contests) and one for normal use. When chasing weak signal DX I'll play with settings to see what I can do. You're lucky to have never had to send your Kenwood radio in for repair. You typically end up sending it to a third party repair shop with the hopes they know what they are doing and do more good than harm.

When there are storms around, I can take away most if not all of the static crashes and they are a clear copy and easily understood. In the afternoons, again on 40M, with stations no more thank 600 kilometers away, I change a couple of my settings BUT still use NR at 5.1 or 5.2 and I have TX EQ set up diferently on TX ESSB (set at 3Kz wide) and I have an armchair copy. I had the "hiss" appear but over time I seem to have been able to fine tune the receive so that I am not noticing it like it was. Is this after mods done by Elecraft recently and the new Synth board?, maybe, but I have learned to operate the K3 better since I went over many of the posts on the reflector and noted what ?thers"had tried. The end result, I now listen to the K3 on speaker without grinding my teeth and the CM500 headphones are perfect for my fractured hearing. This was not always the case, recently Elecraft conducted surgery on my K3 (#679) and I have a totally different wireless (intentionally used TIC) today to the one I purchased in 2007. I had a TS-480S and found the DSP was mostly ineffective (to my ears) and I had other issues with it so I sold it. As an ex-dealer for Yaesu and Kenwood, I can say with some certainty here that their service regimen is quite different to Elecraft and size of the companies does play a role here. I am not going to slam any company, nor am I heaping unwarranted praise, I know from my experience, Elecraft not only back up their products well, they show keen interest in each customer who reports an issue and work very hard to resolve the problem. I don't know that we can expect more. I think Jerry Moore is on the right track here, there are many things that can be adjusted on a K3 and I have been shown a K3 some time ago that the operator had lost interest in. I had a listen, made it sound like mine and the smile on his face was great to see. I have to admit, just abut every setting was changed, I wrote down what I had done and he is now back on air with his K3. The reason I won't be rushing to a K3S is simple, My K3 is too good to sell, and I have never owned a Ham rig for this long, no need to continue the search, I found the right tool for the job I want it to do. 73 Gary On 11 November 2015 at 03:28, Robert Vargas-KP4Y via Elecraft < elecraft at mailman.qth.net> wrote: > Wow, so much for a non-kool aid question...You comments give up my friend! > I have a K3, KX3 and TS-590.

Is all this feedback on how good or how bad NR works about reception of CW (or does it apply to SSB?). Only time I really need NR is when local noise overwhelms normally strong SSB (e.g. signal is running S8-S9 and noise rises up to S8-S9. I find NR will lower the s-meter to about S6-S7 under those conditions but the audio is distorted by NR such that intelligibility is lowered - ergo no help to copy the signal. I've tried several NR settings with some being better but none helping me understand speech better than running without NR. Often NB works better than NR, but NB also tends to distort audio. Using NR with normal noise conditions it is never helpful for improving intelligibility (for me). I will admit that I have extreme hearing issues that make ordinary speech a challenge. So any processing that imparts distortion reduces my ability to understand speech. It seems to me that NR appears to experience IMD with the noise frequencies. To be fair I have not had success using NR with other brand radios, either. The only NR that works for me is in my expensive Bose airline headset. That is working on different nature of noise (probably). To be fair I represent 0.2% of the population that NR probably is ineffective. I have it selectable in my hearing aids and often find it is not helpful, either; rejects noise from behind me but clarity of sound is impacted. In a crowded room full of babble of the multitude, I select the TV/music mode which provides wide-frequency response and I turn vol up to max. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From georgefritkin at yahoo.com Tue Nov 10 13:51:11 2015 From: georgefritkin at yahoo.com (george fritkin) Date: Tue, 10 Nov 2015 18:51:11 +0000 (UTC) Subject: [Elecraft] K3 DSP processor speed In-Reply-To: References: <000001d11bd9$096df7b0$1c49e710$@carolinaheli.com> <497175402.2188481.1447176490749.JavaMail.yahoo@mail.yahoo.com> Message-ID: <1513998932.2878225.1447181471840.JavaMail.yahoo@mail.yahoo.com> I have my hearing checked every year. ?My hearing is good. ?I have 2)K3 and 1)K3S. ?I have never had a hiss problem with any.

Is all this feedback on how good or how bad NR works about reception of CW (or does it apply to SSB?). Only time I really need NR is when local noise overwhelms normally strong SSB (e.g. signal is running S8-S9 and noise rises up to S8-S9. I find NR will lower the s-meter to about S6-S7 under those conditions but the audio is distorted by NR such that intelligibility is lowered - ergo no help to copy the signal. I've tried several NR settings with some being better but none helping me understand speech better than running without NR. Often NB works better than NR, but NB also tends to distort audio. Using NR with normal noise conditions it is never helpful for improving intelligibility (for me). I will admit that I have extreme hearing issues that make ordinary speech a challenge. So any processing that imparts distortion reduces my ability to understand speech. It seems to me that NR appears to experience IMD with the noise frequencies. To be fair I have not had success using NR with other brand radios, either. The only NR that works for me is in my expensive Bose airline headset. That is working on different nature of noise (probably). To be fair I represent 0.2% of the population that NR probably is ineffective. I have it selectable in my hearing aids and often find it is not helpful, either; rejects noise from behind me but clarity of sound is impacted. In a crowded room full of babble of the multitude, I select the TV/music mode which provides wide-frequency response and I turn vol up to max. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com __________________________________________________ ____________ 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 jbollit at outlook.com __________________________________________________ ____________ 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 pincon at erols.com From tposey at nettally.com Tue Nov 10 17:33:58 2015 From: tposey at nettally.com (Terry Posey) Date: Tue, 10 Nov 2015 17:33:58 -0500 Subject: [Elecraft] For Sale: KAT3 Auto Tuner Module for K3 Message-ID: <000401d11c07$e6542cc0$b2fc8640$@nettally.com> I upgraded my K3 to a KAT3A to realize the marginally lower insertion loss on 6M.

Some are better radios, but better is in the eyes {ears} of the beholder. However, those radios of yesteryear, as compared to the current breed of radios from Elecraft, Kenwood, Yaesu, ICOM, Flex and Tentec and ????? are really in the back seat in terms of overall performance. Yes we do have our favorite because of our operation preferences, our QTH, our antenna farm restricted or not, our personal type of noise and a host of other variables. I agree with Rob Sherwood...........If it fits your needs and budget and you enjoy using it, then it is a good radio. Look no further. However, as technology moves forward at present at lightning speed, I believe if a radio is approaching 10 years old or more, one should consider replacing it. 73 Bob, K4TAX K3S s/n 10163 On 11/10/2015 2:06 PM, GRANT YOUNGMAN wrote: > It seems to me that ?drowning in Kool Aid? is no worse than what are little more than anecdotal comments about how one radio is better than another one in regards to noise reduction.

The internal systems are specific for the radio and ham applications. The external devices usually cause more issues than they actually resolve. If you believe you need external signal processing, then you best examine other parts of the system to address the deficiency correctly. I do not use any external EQ or signal processing devices, other than a good mike, a good power amplifier and a good antenna. 73 Bob, K4TAX K3S s/n 10163 On 11/10/2015 4:17 PM, Jim Brown wrote: >> If you use an external EQ and compression device/s, curious what you >> use and/or recommend. > > Nothing -- what's built into the K3 and KX3 are first rate.

Yes, the Flex-67000 should be dropped significantly because it can not produce the both claimed dynamic range and noise floor (weak signal sensitivity) at the same time. Multiple -30 dBm (105 dB DR referenced to -135 dBm MDS) signals will cause ADC overflow with noticeable clicking and popping (distortion) with the preamplifier enabled. Turn off the preamplifier to prevent ADC overflow and the MDS degrades to -118 dB (nearly 20 dB less sensitive) and completely unsatisfactory above 20 MHz or so. 73, ...

Here's what I have set up on my PX3: I use the UP/Down, Ctrl-Up/Down, Left/Right and Ctrl-Left/Right. I have the up/down keys adjust the frequency by 1 Hz, Ctrl-up/down by 10 Hz, Right/Left arrow by 100 Hz and Ctrl-Right/Left arrow by 1 kHz: Up Arrow: UP1; Down Arrow: DN1; Ctrl-Up Arrow: UP; Ctrl-Down Arrow: DN; Right Arrow: UP8; Left Arrow: DN8; Ctrl-Right Arrow: UP4; Ctrl-Left Arrow: DN4; If you have a numeric keypad on your keyboard, you can use those keypad keys as band buttons. For example, you can map KP0 (keypad 0) to BN0; KP1 to BN1; and so on. Those 10 keys get you from 160 to 10 meters. Some day when I have some extra time here at Elecraft I'll put together some tips on macros. :-) Kind regards, Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/feature-request-PX3-keyboard-VFO-control-tp7610210p7610213.html Sent from the Elecraft mailing list archive at Nabble.com.

The ADC does not simply clip, when it overloads, the ADC output becomes total garbage. In other words, I don't know of any reasonable answer. To my mind, the ADC determines the maximum usable dynamic range. If the strong signals overwhelm the ADC maximum signal levels, no signals can be successfully demodulated. Mathematically, the overload situation might not be considered, but with practical devices (ADC), overload is quite possible. 73, Don W3FPR On 11/10/2015 7:32 PM, Fred Jensen wrote: > Question from a mathematics major [whose parents wanted him to be a EE]: > > In a direct-sampling receiver, how do you control the input level to > the ADC to achieve maximum available dynamic range without clipping at > the ADC? > From pauls at elecraft.com Tue Nov 10 19:57:00 2015 From: pauls at elecraft.com (Paul Saffren N6HZ) Date: Tue, 10 Nov 2015 17:57:00 -0700 (MST) Subject: [Elecraft] feature request PX3 keyboard VFO control In-Reply-To: <1447202625366-7610216.post@n2.nabble.com> References: <7194C15B-61E7-4A4B-9F7D-673F1E59EE25@yahoo.com> <1447201788087-7610213.post@n2.nabble.com> <1447202625366-7610216.post@n2.nabble.com> Message-ID: <1447203420527-7610221.post@n2.nabble.com> And the BN commands must be 2 digits.

On the other hand, the Flex uses a really high speed A/D, but it is only 16 bits, if memory serves. That architecture is far more sensitive to gain distribution. Those who have suggested that the Flex may have a problem with all the bits going to 1 in a stress environment may be very correct. IMHO: With the state of the A/D art as it is, I believe Elecraft has the better practical architecture. As soon as low noise, high speed A/Ds become available with greater than 16 bits, my opinion may change. 73, Barry K3NDM ------ Original Message ------ From: "Fred Jensen" To: elecraft at mailman.qth.net Sent: 11/10/2015 7:32:56 PM Subject: Re: [Elecraft] Sherwood Receiver Test Data - K3S Added Today >Question from a mathematics major [whose parents wanted him to be a >EE]: > >In a direct-sampling receiver, how do you control the input level to >the ADC to achieve maximum available dynamic range without clipping at >the ADC? > >73, > >Fred K6DGW >- Northern California Contest Club >- CU in the Cal QSO Party 1-2 Oct 2016 >- www.cqp.org > >On 11/10/2015 3:58 PM, Steve Ellington wrote: >>Looks like the K3S should be above the Flex because the Flex achieved >>2DB >>higher due to: >> >>Footnote Y --- "This is a testing anomaly of a direct-sampling >>receiver." >> >>Congratulations K3S >>Steve N4LQ > >______________________________________________________________ >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 k3ndm at comcast.net From n6kr at elecraft.com Tue Nov 10 20:10:56 2015 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 10 Nov 2015 17:10:56 -0800 Subject: [Elecraft] Sherwood Receiver Test Data - K3S Added Today In-Reply-To: <56428247.6030007@cableone.net> References: <56428247.6030007@cableone.net> Message-ID: <8B47C146-9D88-4B2B-AEC8-9EC604F111CD@elecraft.com> Bill Breeden wrote: > Rob Sherwood added the K3S to his Receiver Test Data page today. Yes. We're pleased to see some excellent test results, including 106 dB of IMDDR3 at 2 kHz for both the 200- and 400-Hz filters. (The K3 came in at 104 dB for the 400-Hz filter. The 107-dB reading is within the usual +/- 1 dB lab/tech repeatability figure.) Also worthy of note: sensitivity of -145 dBm for the new Preamp 2 on 10 meters. This preamp is also used on 12 and 6 meters. I checked with Rob, and that blocking dynamic range number (>154 dB) is *not* a typo. He said he saw less than 3 dB phase noise degradation at 100 kHz with +19 dBm fed into the radio, and stopped at that point. I guess there's no point in melting the signal combiner :) (By the way, Rob's K3S BDR test level of +19 dBm is exactly 10 dB *higher* than the preamp-OFF ADC clipping level of the 6700. With preamp ON, it would clip at an estimated -11 dBm.) 73, Wayne N6KR From dl1sdz at gmail.com Tue Nov 10 20:14:57 2015 From: dl1sdz at gmail.com (Hajo Dezelski) Date: Wed, 11 Nov 2015 02:14:57 +0100 Subject: [Elecraft] feature request PX3 keyboard VFO control In-Reply-To: <1447203420527-7610221.post@n2.nabble.com> References: <7194C15B-61E7-4A4B-9F7D-673F1E59EE25@yahoo.com> <1447201788087-7610213.post@n2.nabble.com> <1447202625366-7610216.post@n2.nabble.com> <1447203420527-7610221.post@n2.nabble.com> Message-ID: Hello Paul, just let everything drop and write a "Px3 Macros for Dummies".

It's a matter of gain/attenuation before the ADC. If, for example, one looks at the Flex-6700 they have four steps of preamplifier gain: 0, 10, 20 and 30 dB. The best MDS and dynamic range is with 30 dB of gain as long as one keeps the *total input signal* below the ADC crapping threshold. If the total input signal exceeds the ADC crap threshold one needs to reduce the front end gain to bring total signal levels below the overload point but that drops the weak signals below the noise floor (typically on a dB for dB basis as preamp gain is reduced). Digital processing gain (decimation) helps with the dynamic range to some degree - e.g. dynamic range is better than the simple number of bits - but it can't do a thing when the ADC overflows and generates garbage data. 73, ...

Remembering that I'm the one who disappointed Mom and Dad when I got A's in Math and B's and C's in EE, and finally transferred to the Math Dept ... I didn't want to imply it was a problem, it was just a question. First off, I believe a direct-sampling SDR is one that essentially does nothing to the entire RF envelope being received except maybe bandpass limit it to the ham band of interest. No guarantee that's correct, and if it isn't, you might as well delete this now. But if it is what direct-sample means, and since the RF envelope is both + and -, in an 8-bit ADC, 127 would be zero, 255 [all 1's] would be the maximum along with all 0's for the negative parts. If the RF envelope is allowed to go above the value that digitizes to all 1's, it will still digitize to all 1's and it's excursions above all 1's are lost [i.e. clipped]. In my experience as a ham, this is rarely if ever a good thing. OTOH, you want as much dynamic range as possible, so you want the strongest input to the ADC be at the all-1's level so the parts of the envelope below that level will digitize to something other than zero [127 in my 8-bit example]. Any signals below that level will digitize to 127 and you'll never hear them. If the gain of the RF stage(s), and I'm assuming there is at least one RF stage, is such that the maximum of the RF envelope is below the clipping point, then it seems to me that signals you might have heard won't be heard because they never got digitized. My question was [and is], do direct sampling receivers employ some sort of AGC to keep the max RF envelope at the clipping point? If the answer is "yes", I have a second question in the wings waiting to be asked. Mom and Dad never recovered from their mathematician's defection from EE, despite having been a wireless addict since age 12. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 11/10/2015 5:06 PM, Barry LaZar wrote: > Fred, > When you have a 24 bit A/D and not looking at the entire spectrum, > this should not be as big a problem as you imply, if gain distribution > is correct. 24 bits should yield a great enough dynamic range to cover > greater than ~ 95% of time; that last ~5% covers your friend next door > with a KW or that thunderstorm over head. 24 bits also allows for some > amplification to overcome the down stream noise figure that may be > greater than ambient. > On the other hand, the Flex uses a really high speed A/D, but it is > only 16 bits, if memory serves.

In a perfect world, the rule of thumb is 6db/bit, 96 db may be accounted for. However, an A/D that can cover all the way to 2 meters has to be very fast > 296 msp, if you believe Nyquist. If you apply hardware AGC in any form, it is reflected across the entire spectrum. And to add further insult, high speed A/Ds have noise figures great enough to mask ambient noise at mid and above HF. That means you need to add a low noise amplifier ahead of the A/D with enough gain to overcome system noise, and that will start to bite into those 16 bits by a function of the gain of the amplifier. You can do some creative things like use tapered gain amplifiers that have a reverse taper so that max gain is at the high end of the spectrum; Typically signals and noise are greater at the lower end of HF even if SNR appear to be greater at the high end. The use of a 24 bit A/D allows for using a simpler approach and yet maintain a high dynamic range. It also disallows using A/Ds that can cover the entire spectrum as they don't yet exist. Unlike math and physics, EEs are more artists than scientists. I suspect the discussions at Elecraft over the architectures would have been very interesting. There are advantages and disadvantages to direct sampling and to the hetrodyne SDR's. Which is better? It's a function of how you want to handle the requirement set which may impact price. Why do I call engineers artists? The sciences are absolute and engineers have to craft a solution that accounts for the compromises, and few engineers always agree on the very same solution. One may like red and another may like blue so the creation comes out as a work of art. The bottom line is that the chosen implementations of Elecraft radios are Gee Whiz and exceed what the casual user needs and appears to be the best for contesting. That last bit is my opinion and I'm sticking with it. Just for the record, I use a KX3. It is lower on Sherwood's rankings, but I think it is the best overall radio out there. It satisfies a greater number of my requirements. And, that is how I colored my solution. ;-) 73, Barry K3NDM ------ Original Message ------ From: "Steve Ellington" To: k6dgw at foothill.net Cc: "Elecraft Reflector" Sent: 11/10/2015 8:51:16 PM Subject: Re: [Elecraft] Sherwood Receiver Test Data - K3S Added Today >Part of the problem here is that Flex won't release the schematic to >the >6000 series so who knows? >I suspect that the AGC-T (Agc threshold) control actually adjust the >input >level to the ADC....somehow. >This control is manual and must be fiddled with per-band as conditions >change.

Since I worked them often in their heyday I guess that makes me officially a fossil). 14 November KSM will extend is normal operating hours well into the evening and will make a special effort to keep 500kc and our MF working frequency (426kc) active to give listeners the best chance of hearing us. Our HF channels will be active as well. And the MRHS amateur station, K6KPH, will be guarding its usual channels for signal reports and regular contacts. KSM will continue operations past 0000Z on these frequencies (in kc): 426 500 4350.5 6474.0 8438.3 12993.0 16914.0 22445.8 K6KPH will guard: 3550.0 7050.0 14050.0 18097.5 21050.0 Numerous medium frequency experimental stations will also be active for this event. Our ops will tune the MF band to see which of these we can monitor. Dr. Fritz Raab has taken the lead on this part of the event. They enjoy getting your reports on the Ham frequencies.

My only experience with an ALS-600 was at a contest station in PJ4 several years ago. I found it to be a really inferior amp - most of the time, I was lucky to get 300W out if it.

Spaces and ; are significant - see the N1MM+ on-line documentation and the K3/KX3 Programmer's Manual. You can insert N1MM substitution macros like #, * and ! as long as the total length of the text to be sent stays below 24 characters. I believe you can also insert control characters by enclosing the hex code in angle brackets, e.g. <0D> for a CR character, etc. I have never tried this next, but I believe you can do something similar from DXLab Suite's WinWarbler by using the External Modem tab in the Config window and setting the Model to Xcvr Ctrl App. Commander must be running for this to work. There may be other configuration settings that are needed along with this. WinWarbler also has a radio control macro similar to the N1MM+ {CAT1ASC} macro that could be used in function-key macros, namely (note the ' ) - but I don't know whether you can use this in combination with other substitution macros, or whether you can embed control characters in the text. 73, Rich VE3KI NR4C wrote: > There was a recent post on a reflector (don???t know which one) that listed n1mm function key macros for sending FSK using KY commands I think.

If your situation is such that you do not encounter strong stations within that 2.7 kHz bandpass, you can do just fine with only that filter, the DSP is quite capable of isolating a single signal with no problem. The "problem" comes in if you have strong signals (S-9 +40 or more) near the frequency you are trying to receive. Those strong signals will activate the Hardware AGC and will cause AGC "pumping" - meaning that the signal you are trying to copy will appear to go up and down in strength. What is really happening is that the strong signals within the passband of the 2.7 kHz filter are activating the K3S hardware AGC and reducing the receiver sensitivity to keep that strong signal from overloading the ADC. You may not even hear that strong signal because it is outside the DSP filter bandpass. In other words, if you experience problems with the desired signal strength going up and down, then that strong nearby signal that you cannot hear may be to blame. A narrow roofing filter will not allow that strong signal into its passband and is a benefit during contesting (or DXing in crowded conditions. This was discussed at length in the early days of the K3.

I've received a few inquiries about my website (or lack thereof) and wanted to let all my customers know that I am still in business.

So I am without a site for the moment while I actively search for a new home.

I apologize for any inconvenience to my current or future customers and will hopefully find a new home soon. I'm currently looking at QTH.com as a possible home with my own domain name.

In-Reply-To: References: Message-ID: Hajo, I like your macro. I didn?t realize how poor the band conditions were until I tried to check into a state-wide 75 m net last night. Here are the two things I have programmed in my KX3 at the moment: PF1 - (Macro 1) MD3;SWT25;SWT25;FT1;SB1;UPB4;MN142;MP001;MN110;SWT27;SWH18;MN255; (Macro 2) SB0;FR0;MN142;MP000;MN110;SWT19;SWH18;MN255; PF2 - Turns on and off my ATU. PF1 looks more complicated than it is. As it is written, Macro 1 puts the KX3 into CW mode, puts the radio into split mode and moves the transmit frequency up 1 kHz (UP 1). Macro 1 goes into the Macro 1 slot in the KX3 program and Macro 2 goes into the Macro 2 slot. Macro 1 will load on the first long press of the PF1 button and pre-stage Macro 2. The second long press will execute Macro 2. It can be configured with different modes, power settings, split settings, etc. 73, Joel - W4JBB > On Nov 12, 2015, at 5:56 AM, Hajo Dezelski wrote: > > Hi, > > Although I have done my share in programming and have studied the > programmers reference manual and have played with the macro examples, I > must confess, that I am sometimes lost.

On page 36 of the K3s manual (page 34) of the K3 manual the setup is described. The K3 doesn't care if the excitation comes from the computer via the KY command or from the paddles so have a ball my friend. You can use the CW macros on RTTY.

Since multiple components burned through the LPF PC board, that is major damage and would require replacement of the whole LPF board, which is a major cost component of the amp. (Taking out this board and replacing it requires disassembly and reassembly of a major portion off the amp.) The repair cost also includes the tech time to diagnose, disassemble, repair, reassemble, retest and do full production TX burn-in of the amp on all bands. Component failure like this can occur in any manufacturer's radio or amplifier for many reasons, such as power line surges, nearby lightning strikes, operating with excessive SWR, transmitting into a wrong antenna etc. You do not need to be operating on a particular band, or even have the amp or radio on to incur lightning damage. This can also cause partial damage to components that then shows up as a failure later after additional operation. As a side note, every year during lightning season we see a significant increase in all sorts of 'interesting' repairs sent in to us on all of our products. Many times the user is not even aware that a strike occurred somewhere nearby while they still had their antennas connected. I'll review your repair report with our techs to make sure we didn't over charge for anything. I'll also check to see if they mis-identified which band the destroyed LPF components were from. 73, Eric elecraft.com _..._ > -----Original Message----- > From: Elecraft > [mailto:elecraft-bounces at mailman.qth.net] On > Behalf Of w4grj > Sent: Thursday, November 12, 2015 7:14 AM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] KPA500 troubles > > I need to correct the information on the repair > cost > > It was $615 with shipping not $650 as I previously > reported. > > Jack W4GRJ > >> On Wed,11/11/2015 12:10 PM, W4GRJ wrote: >> Got the KPA500 back from Elecraft. >> Problem found: L22 and other components in the > 60M low pass filter >> circuit burnt through the LPF PCB. > From georgefritkin at yahoo.com Thu Nov 12 10:42:22 2015 From: georgefritkin at yahoo.com (george fritkin) Date: Thu, 12 Nov 2015 15:42:22 +0000 (UTC) Subject: [Elecraft] Sherwood Receiver Test Data - K3S Added Today In-Reply-To: <56440FD2.2060003@sbcglobal.net> References: <56428247.6030007@cableone.net> <56428870.8030509@subich.com> <56428d32.6ae3420a.11493.04e3@mx.google.com> <56428F32.6040909@embarqmail.com> <5642BE4B.1000203@blomand.net> <56440FD2.2060003@sbcglobal.net> Message-ID: <2026609622.3944566.1447342942360.JavaMail.yahoo@mail.yahoo.com> If the TS990 had metal knobs not plastic, it might make 75 pounds! 73deGeorge, W6GF On Wednesday, November 11, 2015 8:09 PM, Jim Lowman wrote: Well, I guess the Kenwood TS-990S that I just unpacked doesn't qualify, even by virtue of its 54-pound weight.? :-) No tubes, less than 75 pounds, and no place to tie a rope. 73 de Jim - AD6CW P.S.?

I did send a message to Wayne for his review, so I don't want to cause double efforts on this..I appreciate the review. Since I do live in a active lightning area, I have a well grounded station and polyphaser surge protection. Coax is grounded when not in use.. possible but I don't think it was lightning related. In 15 years at this QTH I have never had a lightning issue with my station or anything in the house.

I don't use the signal link at all. I would probably have slightly better bandwidth and signal, but I just use the on board sound card with a proper TRRS adapter to split off the mic and headphones. I got mine from amazon for 6 bucks maybe. Then I just use the USB from the KX3 and connect the headphone out of KX3 to the mic in of the surface and headphone out of surface to mic on the KX3 with the cable set that Elecraft sells. I've made plenty of contacts that way without any issues with DXLab Suite, HRD and FLDigi and have used it with RMS Express via the winmor protocol. You may have to adjust the levels of your sound card in the surface, but as I said, I use it quite regularly without any problems what so ever. I do have a signal link, but I have yet to use it with my setup. Other than the adapter, adjusting levels, and plugging in cables, it should just work. Just make sure your software knows which com port the KX3 is on. I sometimes forget that part and bang my head for a while trying to figure out why it's not working right. hi hi I love the setup and it's nice not having to drag around extra cables and boxes in my suitcase just to work digital. Again, you may have a cleaner and/or slightly strong signal with a dedicated sound card like the signal link, but I haven't had any problems making contacts without it. And to me, it's one less point of failure I have to worry about. YMMV. 73, Tim KG1GEM On 11/11/15 10:42 PM, grif80128 at comcast.net wrote: > I'm interested in trying to get my MS Surface Pro 3, great to pack on the motorcycle, hooked up and usable with my KX3, also great to pack on the motorcycle, for portable PSK31.

This happened to me a lot when I used this keying technique with N1MM. 73 de Dick, K6KR > On Nov 12, 2015, at 07:05, John Lawrence via Elecraft wrote: > > Exactly, I get a series > of PTT key up pulses in a series of, " - - - - - - - " each dash representing the short PTT keyup > pulses on the K3 and it's always the seme series of PTT key ups.

There is no requirement to have a "measured" antenna; calculated gain (loss) is permitted. It's kind of like high school algebra, you just have to show your work. With modern analysis tools such as Eznec, it is almost trivial to do so, if you know what you are doing. Soapbox mode on: When I was first licensed, we were relegated to using the DC input (Vp x Ip) as our power limit because it was assumed that we did not have the ability to measure RF power accurately. As technology improved and this was no longer the case, the power limit(s) was changed to transmitter output power. Now we have been given a band, where like every other service, we get to use ERP, since the FCC, giving us the measure of the doubt, assumes that we know how to determine it.* We should, it's a requirement of *?97.13*: "(c) Before causing or allowing an amateur station to transmit from any place where the operation of the station could cause human exposure to RF electromagnetic field levels in excess of those allowed under ?1.1310 of this chapter, the licensee is required to take certain actions. (1) The licensee must perform the routine RF environmental evaluation prescribed by ?1.1307(b) of this chapter, if the power of the licensee's station exceeds the limits given in the following table:" * Also see https://www.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65.pdf where on page 16 it says: "Many antenna-modeling programs are based on NEC or MININEC analysis. These programs often yield very accurate results. An amateur enters his or her antenna dimensions and ground characteristics into the antenna model, and the program is then executed to calculate electric and magnetic field strengths near the antenna. These programs do require some amount of user skill, but the average amateur should not experience too much difficulty in using them. The ARRL Web page maintains a list of software vendors who sell antenna modeling software (http://www.arrl.org/news/rfsafety)" Soapbox mode off.

BUT -- there's a certain vagueness to the FCC definition, in that it does not specify mounting height of the reference dipole, making comparisons to a vertical antenna, which relates to mounting height quite differently, at least a bit squishy. 73, Jim K9YC From joel.b.black at gmail.com Thu Nov 12 07:23:48 2015 From: joel.b.black at gmail.com (Joel Black) Date: Thu, 12 Nov 2015 06:23:48 -0600 Subject: [Elecraft] What are your favorite K3 and KX3 macros?

PF1 looks more complicated than it is. As it is written, Macro 1 puts the KX3 into CW mode, puts the radio into split mode and moves the transmit frequency up 1 kHz (UP 1). Macro 1 goes into the Macro 1 slot in the KX3 program and Macro 2 goes into the Macro 2 slot. Macro 1 will load on the first long press of the PF1 button and pre-stage Macro 2. The second long press will execute Macro 2. It can be configured with different modes, power settings, split settings, etc. 73, Joel - W4JBB > On Nov 12, 2015, at 5:56 AM, Hajo Dezelski wrote: > > Hi, > > Although I have done my share in programming and have studied the > programmers reference manual and have played with the macro examples, I > must confess, that I am sometimes lost.

The issue is as described below past the dashed line. Note that the issue happens even if I haven't been transmitting. Don Wilhelm helped me attempt to troubleshoot the issue. We eliminated the base K2 as the source. After that, at Don's suggestion, I installed the KPA100 upgrade kit - no success. At this point we gave up. Recently I replaced D16 & D17 on the KPA100 after reading about similar problems caused by the damaged diodes. Still no luck. Has anyone out there had a similar issue? 73, Jim Elmore WA4YWM ------------------------------------------------------------------------------------------ I have a K2 serial no. 4729 with the 100W amp which I have been using for almost 10 years. It recently developed a problem with the following 2 symptoms: 1. After operating for some time (perhaps 1-2 hours) the Tune function will begin to display 1 W with a 1.0-1 SWR on all bands. It normally displays 22-23W with the correct SWR shown. 2. At the same time, if I attempt to transmit, the K2 will apparently begin to draw too much current and it shuts down and re-starts. The Tune function also shuts the K2 down at this point. I observed the same behavior on a dummy load - to eliminate an antenna or feedline issue. I also left the power supply on while letting the K2 cool down to see if the supply was the source of the problem. Apparently not since the K2 would operate for a significant time after turning the K2 back on. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-w-KPA100-power-resets-after-approximately-2-hrs-of-turn-on-time-tp7610298.html Sent from the Elecraft mailing list archive at Nabble.com.

If so, you have a problem with the power circuits in the base K2 or the components that feed the base K2 from the 12 volt power in the KPA100. First and most likely, check the crimp pins in the housing that plugs into K3 RF board P3 (AUX 12V). If the crimp pins are 'mashed', they will not make good connection - get new crimp pins and insert them properly into the housing. If those are OK, check the red and black wires - if they have ever been pinched between the KPA100 shield and the K2 side panel, they may have broken wires, replace the wires (use stranded wire). Check the soldering of KPA100 D9. In the base K2, check the soldering of F1 and the power switch. You might consider replacing F1. 73, Don W3FPR On 11/12/2015 8:27 PM, wa4ywm wrote: > I originally posted this in July and I still have the problem.

That said, I think you're making this too complicated. The rule states: "For the purpose of computing ERP, the transmitter PEP will be multiplied by the antenna gain relative to a half-wave dipole antenna. A half-wave dipole antenna will be presumed to have a gain of 1 (0 dBd). Licensees using other antennas must maintain in their station records either the antenna manufacturer's data on the antenna gain or calculations of the antenna gain." Note, there is no mention of any directivity, or lack thereof, so I would take it that this is a theoretical free-space value. Zero dBd is equal to 2.15 dBi so modelling another antenna and calculating its gain in dBi, which is the normal modelling outcome, then subtracting 2.15 from that number yields the gain relative to an ideal dipole, i.e the FCC reference. Right away this gives a significant advantage to an actual horizontal dipole that has ground gain, assuming that the dipole is rotatable and the elevation angle is favorable for the path. Absent that, and considering the physical size one would probably use a vertical and bump up the power to account for the inevitable losses.

The P3SVGA does not separately decode the CW. If you are not getting faithful copy of VFO B on the K3 to the P3, something is amiss in the station setup.

The text display on the P3/SVGA and P3 Utility are mutually exclusive - only one should be turned on at the same time.

I am completing a K2 build that will include the KAT2. The 2-pin connector (P6) on the K2 RF Board connects to the RF input on the KAT2. There is a clearance problem where inductor L20 overlaps the footprint of P6 on the RF board. This overlap is about 2 mm in my case. The recommended solution to this overlap is to simply unsolder L20 and roll it forward to eliminate this overlap. I am uncomfortable with this and am thinking about using an alternative method to make this connection.

I routinely swap out full options when doing troubleshooting (substitution is the quickest way to isolate a problem). If you use a non-standard connector, that cannot be done. That 2mm will not cause a problem at all. L20 will likely move toward the rear a bit if you bend over C202 and give it a slight push. 73, Don W3FPR On 11/13/2015 5:43 PM, David Brown wrote: > This post is for K2 builders that have the internal KAT2 ATU.

Because of the modularity, I'd guess that when they're servicing K2's, they might swap in a known-good module to troubleshoot a problem. Changing the connector makes that hard[er]. That said, note that there are in fact two of those 2-pin Molex-type connectors on the RF board. Note also that the each of the 2 cables will reach to either connector. Swapping them will short the 12 V and blow your fuse[s] ... hopefully. I don't recommend changing one of the connectors, but I do recommend some bright nail polish on one of them [both sides] to lower the probability of misconnection. I'm sure you can deduce how I know this. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 11/13/2015 2:43 PM, David Brown wrote: > This post is for K2 builders that have the internal KAT2 ATU.

The P3/SVGA simply gets a copy of the K3's decoded text and displays it on the screen. There is no separate decoding being done on the SVGA card. Therefore the problem is likely in the serial port between the K3 and P3, or some other program is fighting for the data. Check the serial cable between the K3 and P3. If you're still having trouble, email me directly at Elecraft.

The sound card would be high quality and have a low latency for use on software such as the MS-DMT M110A modem software. Such a sound card would allow a connection to the KX3 without resorting to special cabling for headset with mic that would have to split the audio in/out and ptt line/foot switch.

One could do that, of course, but your original post brought ground conductivity into the computation, which is, IMO, entirely appropriate. FWIW, I've done some extensive modeling studies of horizontal and vertical antennas at various mounting heights; horizontal antennas don't care much about soil but care a lot about height; vertical antennas care a bit about height and a lot about soil. That work is on my website. I think I would use average gain of the antenna as installed as the basis for compliance with the Rules, but the question remains, what height for the dipole? :) This is, for me, purely academic. My soil being terrible, a vertical is a poor choice for 60M, and I have a bunch of high horizontal dipoles, so I'd use one of them. :) BTW -- there's a 2-part piece on this topic by Rudy Severns in QEX this past summer, specifically addressing very short verticals for the 630m band. 73, Jim K9YC From anchor at chorus.ocn.ne.jp Sat Nov 14 00:03:20 2015 From: anchor at chorus.ocn.ne.jp (JE0LFI) Date: Fri, 13 Nov 2015 22:03:20 -0700 (MST) Subject: [Elecraft] [elecraft] PX3 Firmware 1.39 General Release In-Reply-To: <1447088627756-7610136.post@n2.nabble.com> References: <1446768491585-7610017.post@n2.nabble.com> <1446864334818-7610078.post@n2.nabble.com> <1447088627756-7610136.post@n2.nabble.com> Message-ID: <1447477400955-7610330.post@n2.nabble.com> Hi Paul My PX3 has been reset(MENU and PWR).

This can also cause partial damage to components that then shows up as a failure later after additional operation.? wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 13, 2015, at 9:57 PM, Vic Rosenthal wrote: > > But why would a filter for a band that the operator had never used fail? > > Vic 4X6GP/K2VCO > >> On 13 Nov 2015, at 11:52 PM, Wes (N7WS) wrote: >> >> Why would one filter, that like just like all of the others is switched into the circuit by a relay on each end, fail while none of the others do not? >> >>> On 11/11/2015 1:32 PM, Jim Brown wrote: >>> >>> The LPF is on the output of the amplifier.

There seems to be more extra space inside the PX3 cabinet for options, if you don't mind being tied to a PX3. I don't necessarily need an internal sound card. I'm very happy with the external soundcard I use with my notebook computer. However, I won't ever buy another transceiver that doesn't have a dedicated Data jack, even if it does say Elecraft on the front. I find it a pain to be constantly unplugging cables and inserting new ones each time I change modes. I'm afraid of wearing out the 3.5mm jacks on the KX3 with all the inserting in and removing of plugs. I know I can use Y-adapters, but that only adds to the considerable mess hanging off the side of my KX3. 73, Ken Alexander VE3HLS On 2015-11-14 7:19 AM, Erlend Grimseid wrote: > I would buy some like that in a flash.

There were requests on the original feature lists for the digital voice recorder back at the beginning of the K3. The voice recorder was available very early. Usually the user wants to use his own voice for synthesized speech, a rather complex task usually done by logging software running on a PC. This would be a PC that has the software for forming the letter, number and special message files needed for automatic contest speech in a contest with serial numbers, etc. The logging program then assembles those files into sequential speech using directory and file names specified by the program via a sound card. These tasks require developed software, which will have been developed for the two common hosts and operating systems. That would make the request suspiciously like inserting a mini PC into the K3. Interesting idea. Would worry about all the misc RF noise generated by a PC. And the heat. Still interesting ignoring all the practical issues to solve. If transportability was in mind and I had to have it tomorrow, I'd get a Surface Pro 3, load all the requisite software and files, and pack it in the same case as the K3. 73, Guy K2AV On Friday, November 13, 2015, Scott Gillen ZL1CHM wrote: > I'm wondering if Elecraft produces or has considered producing a speech > synthesiser board for any of there radios? > > 73 > Scott > ZL1CHM / N0HO > Auckland New Zealand > > Sent from my iPhone > ______________________________________________________________ > 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 k2av.guy at gmail.com > -- Sent via Gmail Mobile on my iPhone From k7jltextra at gmail.com Sat Nov 14 09:40:25 2015 From: k7jltextra at gmail.com (John Hendricks) Date: Sat, 14 Nov 2015 06:40:25 -0800 Subject: [Elecraft] KX3 Internal soundcard In-Reply-To: <1A3154CF-CE91-446A-A555-C7FFC3A534AC@gmail.com> References: <1447471057208-7610327.post@n2.nabble.com> <1A3154CF-CE91-446A-A555-C7FFC3A534AC@gmail.com> Message-ID: I agree that some type of menu selectable data connection would be a very nice addition to the KX3.

My modes of operation are principally digital, either meteor scatter, PSK31, RTTY, and WSJTx and its many variations. All of these are what I would term 100% duty cycle. For meteor scatter I run the KPA500 at 350W usually and the transmission periods vary from 15 seconds to a full minute. I hear a few pings and creaks from the heatsink but only rarely do the fans get to mode 4 and when they do, it only lasts for 15 to 20 seconds after transmission ceases. On PSK31 and JT65(HF) the amplifier is not used as the rule of thumb is 25 to 30 Watts. On RTTY for short contest exchanges, the amplifier is run to its limit. The KPA-500 was purchased in April of 2014 so it has seen some service, particularly on meteor scatter and ionospheric scatter. I do dumb things on occassion and the amp faithfully faults out and I realize what I have done. I have owned many rigs and amps in my 62 years of ham radio and I personally rate my Elecraft station as superior to all the others, names withheld to protect the innocent. Just my two cents.....

With the new syn QRQ mode becomes finally what it was intended for, a speciality mode for doing 80 WPM full break-in. And the ridiculous less than one millisecond TX RX TX state change budget, required to hear between bauds at that speed, mandates a no-frills necessities only lean and mean state change task list in the programming executed between bauds. I would think that it's time to drop the confusing old/new QSK distinction if new Syns are detected. Or keep and call them smooth/sharp or some such, sharp being I want to hear as much as possible between bauds, smooth being hear as much as can without clicky or popping sounds. 73, Guy K2AV On Friday, November 13, 2015, ok1rp wrote: > Yes, it is as Guy said and I agree. > Normal QSK is improved as reported and tested by several ops and I do not > worry which QSK is set at 40wpm or so on my K3 with new KSYN3A. > I just mentioned to Barry that new QRQ mode is off when RIT is used...;) > > 73 - Petr, OK1RP > ----- > http://ok1rp.blogspot.com > -- > View this message in context: > http://elecraft.365791.n2.nabble.com/KSYN3A-and-QSK-tp7610301p7610306.html > Sent from the Elecraft mailing list archive at Nabble.com. > ______________________________________________________________ > 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 k2av.guy at gmail.com > -- Sent via Gmail Mobile on my iPhone From M0XDF at Alphadene.co.uk Sat Nov 14 10:38:31 2015 From: M0XDF at Alphadene.co.uk (David Ferrington, M0XDF) Date: Sat, 14 Nov 2015 15:38:31 +0000 Subject: [Elecraft] OT: New W8FGU Enclosure Website In-Reply-To: References: Message-ID: <568A66F9-BD79-4B25-895F-01B6536EDD1A@Alphadene.co.uk> Nice Dave ? -73 de M0XDF > On 14 Nov 2015, at 14:56, "dave at w8fgu.com" wrote: > > Hi Everyone, > > Well, after receiving many recommendations about QTH.com, I went ahead and got setup with Scott and now have a new home for my site: http://w8fgu.com > > I just put the site up last night so I hope I have everything working, but if you find anything out of the norm, please drop me a note.

The fan does get to stage 4 fairly easily on six meters (for me). I run 430-480W out most of the time. I kick the manual fan setting to stage 4 when I start a run and if it takes too long, it will go stage 5 the last few seconds of each transmission and stay there until a few seconds (5 normally) after the end of transmission. When I'm done with the QSO, I move the fan back to normal. Starting with it on 4 just delays the onset of stage 5. I work very little JT65 and no PSK.

A lot of DXpeditions on 160 use 1823.0Khz for transmit listening up 1-5khz. Every time the K3 goes from A RX to B TX, and back again, it involves a cur-chunk from the KAT500 whether the tuner is in Auto or Manual. It happens where ever there is a segment boundary but is particularly annoying in the DX portions of the CW bands. Would it be possible to alter the K3's firmware to recognize a Split or XIT from the K3 as a Transmit on B VFO or XIT only? I know it would not affect owners of rigs other than the K3/K3s.

A CW signal should display offset from the center by the amount of your sidetone pitch. The K2 uses high side VFO injection for bands below 15 meters. For 15 meters and above, it uses low side VFO injection. That is the reason you are seeing the change on 15 meters and above. 73, Don W3FPR On 11/14/2015 11:15 AM, K8AC wrote: > I've been using my K2 with LP-Pan and NaP3 for a few months on the lower > bands and just recently got on 20 and 15 meter CW with it.

When you are in CW mode, you want the baseband to be LSB. This means for 80m-17m, you need to put the BFO below the filter passband, since the output of the 1st mixer is already LSB, but for 15m and 10m the output of the 1st mixer was USB, so you need to flip it by placing the BFO above the filter passband. ?This is why the perceived offset on NaP3 goes negative for the upper bands. Maybe you remember when you did the CAL FIL procedure, one of the parameters you had to set was in fact the BFO frequency. Why is there a difference between 20m and 80m-30m? I?m guessing maybe you are using a different filter on 20m, which has a slightly different BFO offset. For 15m and 10m, if you use a different filter, the change in BFO offset will be even more significant, since when you set the width of the filter, it mainly affects the upper edge of the passband, and so the BFO offset must be adjusted to compensate (remembering that for 15m and 10m the BFO is set above the passband rather than below). ??? --? 73 de Matt VK2RQ On 15 novembre 2015 at 3:16:21 AM, K8AC (floyd at k8ac.net) wrote: I've been using my K2 with LP-Pan and NaP3 for a few months on the lower bands and just recently got on 20 and 15 meter CW with it.

My desire for such a box comes from my habit of switching to a band and looking for signals with the PX3. When I see an interesting signal, I switch to the appropriate mode to work the station. This habit means I'm switching between SSB, CW, Data A, and AFSK A all the time. Saying this switching is a lot easier on the K3 than it is on the KX3 is an understatement. (The remaining problems in the K3 are turning VOX on for data and off for SSB and switching between DATA A and AFSK A. I think I have solved the data mode switching problem using the per-band frequency memories. I have one for CW, one for SSB, one for DATA A, and one for AFSK A. Each selects a frequency in the appropriate part of the band.) This box would include connectors for connecting the PX3 and its pass thru for a computer, the microphone, an external CW key, headphones, and DC power. It would include controls for headphone volume so the headphones could be used when tuning RTTY signals. I do worry about building the physical plug array so all the plugs make a reliable connection. Thanks fo Ken's message, I'm thinking of including sound card functionality and a microcontroller to perform mode switching and other functions via the async ascii programming interface. I don't expect to have time to start this project anytime soon, and I would be delighted if Elecraft or someone else picked it up and ran with it. 73 Bill AE6JV On 11/14/15 at 4:58 AM, k.alexander at rogers.com (Ken Alexander) wrote: >I don't necessarily need an internal sound card.

If I center the signal on the NaP3 indicator using my most-often-used 400 Hz filter, advancing through subsequent narrower filters I see just a bit of movement of the signal relative to the pointer. But, with the two wider filter positions, the movement is substantial and would require a much larger or smaller offset in NaP3 to get the signal aligned with the pointer. With a bit of work, I can probably get the signal and pointer pretty much aligned by tweaking the BFO settings for the wider filters. I'll watch the shape and position with Spectrogram while doing that. By the way, this isn't just an academic exercise. When I'm operating split and chasing DX, I often need to be able to position the transmit VFO pointer on a signal and have the K2 exactly on that frequency and not a couple hundred Hz away. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-and-NaP3-IF-offset-values-tp7610348p7610356.html Sent from the Elecraft mailing list archive at Nabble.com.

From the symptom, I suspect it's nowhere near resonance on 12m, and the KAT500 is jumping through hoops to get power into the feedline. And, if the antenna is a poor match to the feedline (which is why it would need a lot of tuning), the loss in the feedline is likely to be high. 73, Jim K9YC From zl1chm at gillen.co.nz Sat Nov 14 18:27:20 2015 From: zl1chm at gillen.co.nz (Scott Gillen ZL1CHM) Date: Sun, 15 Nov 2015 12:27:20 +1300 Subject: [Elecraft] Speech bord for any of the Elecragt rigs?

If you use CW-R on 15m & 10m, then that will help you match up the BFO frequency on those bands, as again the BFO will be placed on the low side of the crystal filter pass band, although the ?pitch you hear as you tune up the band will go high to low instead of low to high. To really fix this this up properly though would require some enhancements to NaP3. Not sure if the author ever released the source code though. 73, Matt VK2RQ On Sat, Nov 14, 2015 at 12:29 PM -0800, "K8AC" wrote: I suspect that the difference I saw in the offset for 20M was indeed due to a different filter selection. If I center the signal on the NaP3 indicator using my most-often-used 400 Hz filter, advancing through subsequent narrower filters I see just a bit of movement of the signal relative to the pointer. But, with the two wider filter positions, the movement is substantial and would require a much larger or smaller offset in NaP3 to get the signal aligned with the pointer. With a bit of work, I can probably get the signal and pointer pretty much aligned by tweaking the BFO settings for the wider filters. I'll watch the shape and position with Spectrogram while doing that. By the way, this isn't just an academic exercise. When I'm operating split and chasing DX, I often need to be able to position the transmit VFO pointer on a signal and have the K2 exactly on that frequency and not a couple hundred Hz away. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-and-NaP3-IF-offset-values-tp7610348p7610356.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to matt.vk2rq at gmail.com From w4grj at satterfield.org Sat Nov 14 19:35:26 2015 From: w4grj at satterfield.org (Jack) Date: Sat, 14 Nov 2015 19:35:26 -0500 Subject: [Elecraft] FS KPA500 Message-ID: KPA500 is sold Jack W4GRJ From bill at wjschmidt.com Sat Nov 14 19:38:20 2015 From: bill at wjschmidt.com (Dr. William J.

And...can the unit be operated without a computer connection? The KAT500 Utility is a CONFIGURATION UTILITY. Look at it. It allows the user to choose which outputs CAN be used on each band. That set of choices is saved to the unit. Then, during operation, the user chooses the output as he operates using a front panel button that cycles through those choices. Let's say, for example, that my only 30M antenna is on output number three. I set the KAT500 so that it automatically goes there when I go to 30M. Now, I have a 20M-6M SteppIR on output number one and a 20m monobander on output number 2. When I go to 20M, the Ant Selector button on the KAT500 toggles between output 1 and output 2. This is a simple example. There are many possibilities. My station has monoband antennas for 160, 40, 20, 15, and 10, so I select them with an external switch to output number 2. And, like the previous example, my SteppIR is on output number 1. On these bands, the front panel button toggles me between outputs 1 and 2. I happen to have three antennas for 40m, so the third one gets switched externally between it and the 30M antenna to output #3. So on 40M, the front panel button toggles between all three outputs. Put up a new antenna? Use the KAT500 Utility to change the config as you need it. Hope this helps. 73, Jim K9YC From NZ3O at arrl.net Sat Nov 14 23:31:33 2015 From: NZ3O at arrl.net (Byron Peebles) Date: Sat, 14 Nov 2015 23:31:33 -0500 Subject: [Elecraft] KAT500 Re-Tuning In-Reply-To: <5647B709.7030605@audiosystemsgroup.com> References: <5647A28F.6090408@arrl.net> <5647B709.7030605@audiosystemsgroup.com> Message-ID: <56480AA5.9060809@arrl.net> M2 Log Periodic flat from bottom to top.

All you need to do is select the antenna of interest from the Front Panel - no computer required. KAT500 Utility can make the setup of the various bands and antennas easier than doing it manually. That does require a computer, but once set up, no computer is required. You can setup the KAT500 without the use of KAT500 Utility, but it will take longer and require more mechanical steps. The Utility program can be downloaded from the Elecraft website - it does not come already installed with the KAT500. 73, Don W3FPR On 11/14/2015 10:09 PM, Robert Clark wrote: > Doesn't the KAT500 come with a utility program already installed?

To make it work for the upper bands, you'd need to be able to specify a separate global offset value based on the band you're on. I'm afraid there isn't much interest in making things work right for the K2 at this point. I see that NaP3 has the ability to poll the rig for the IF frequency and filter shift and that appears to be for the K3. I don't believe the K2 has the ability to respond to those commands. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-and-NaP3-IF-offset-values-tp7610348p7610373.html Sent from the Elecraft mailing list archive at Nabble.com.

Other suggestions. First, put it on bypass and see what the SWR indication is. If it's reasonable, go to MAN mode, force a tuning (put K3 in TUN mode) and let it tune. Carefully check the entire coax path between K3 and the antenna. All connectors should be finger tight, then tighten with gas pliers. Any indication that the coax is wet? Moisture entering anywhere along the run will usually migrate all the way down to the lowest point. Open connectors to see if there's any moisture. A good way to test is to use a tissue or paper towel as a probe. If you have TDR capability, look at the feedline for any discontinuities. You should see connectors, the antenna, and any switching between the antenna and your test point. Most vector analyzers can do TDR. If you don't have one of them, ask around your ham neighbors to borrow one (and ask them to help you do the measurement). 73, Jim K9YC From jim at audiosystemsgroup.com Sun Nov 15 13:19:56 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 15 Nov 2015 10:19:56 -0800 Subject: [Elecraft] Looking for more P3 Operating Information?

If I don't find a very strong signal, what conditions, in your experience, would create a signal strong enough to turn on the K3 attenuator? Or are there other circumstances that would cause the K3 attenuator to turn itself on? As additional info, if the preamp is on and the radio is switched to 80M, the preamp will turn itself off. This indicates an RF signal of +3 to +10dBm- or S9+80 or so- when the radio is switched to 80M.

If you have the attenuator on for 160 meters, then leave that band, it will still be set on when you return to 160 meters. While switched to 160, turn the attenuator off - change to another band and then go back to 160m - the attenuator should be off. Similar for your preamp statement for 80 meters. 73, Don W3FPR On 11/15/2015 2:06 PM, Dennis wrote: > I have a situation where a K3 with the attenuator off, when > bandswitched to 160M, turns the > attenuator on.

The need for this functionality is very apparent when running split on 40m SSB when the DX is below 7.1 MHz and listening up much higher than 5KHz for anyone using a narrow bandwidth 40m antenna. Consider that the KAT500 already tuned the antenna on your TX, so the "fix the antenna solution" doesn't apply. Listening ~50KHz away should not require any retuning since the tuner's settings at your TX should be good enough for RX. Here is how it would work: 1. When the KAT500 sees a *transition* from split off to split on... a. The KAT500 would recall settings for TX Frequency or retune (under the VSWR settings condition) when it sees RF for the first time after this split transition 2. When split is on (Split mode) b. The tuner should not change any settings regardless of frequency/band - except under VSWR conditions based on settings. c. Perhaps both the "Auto" and "Man" indicators would be on in order to indicate this mode on the KAT front panel. 3. When the KAT500 sees a transition from split on to split off then go into "normal" (non Split) mode. The main reason I am using the tuner is because of a compromise antenna. If the antenna was flat enough across the band I wouldn't even engage it. In my specific situation there is also at KPA500 connected, so the way that the KAT500 works today will result in the KAT inhibiting the KPA while it retunes/recalls. Although fast, I suspect that the amp is not engaged initially when I send (speak) my call sign in the pile. On very rare occasions there is also a KPA VSWR Fault. While probably not an issue, the amount of relay chatter in very short period of time between fast RX/TX/RX transitions is a bit unsettling. 73, Cliff K3LL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Sunday, November 15, 2015 10:04 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KAT500 Re-Tuning On Sat,11/14/2015 8:37 PM, Byron Peebles wrote: > I will put the antenna analyzer on it tomorrow and make sure it's > still solid after all this wind.

I've been knee deep in the KPA500 serial protocol (with great results thanks to Jack W6FB) and thought they may have some high level similarities, but not really. Do you know how the KAT500 interprets frequency, if driving only the band data lines (BAND0-3) via an external TTL device? Does it pick middle of the band if there is no last used frequency? 73, Cliff K3LL -----Original Message----- From: Cliff Frescura [mailto:cf at cfcorp.com] Sent: Sunday, November 15, 2015 2:58 PM To: 'Cady, Fred'; 'Elecraft at mailman.qth.net' Subject: RE: [Elecraft] KAT500 Re-Tuning Apparently yes.

The need for this functionality is very apparent when running split on 40m SSB when the DX is below 7.1 MHz and listening up much higher than 5KHz for anyone using a narrow bandwidth 40m antenna. Consider that the KAT500 already tuned the antenna on your TX, so the "fix the antenna solution" doesn't apply. Listening ~50KHz away should not require any retuning since the tuner's settings at your TX should be good enough for RX. Here is how it would work: 1. When the KAT500 sees a *transition* from split off to split on... a. The KAT500 would recall settings for TX Frequency or retune (under the VSWR settings condition) when it sees RF for the first time after this split transition 2. When split is on (Split mode) b. The tuner should not change any settings regardless of frequency/band - except under VSWR conditions based on settings. c. Perhaps both the "Auto" and "Man" indicators would be on in order to indicate this mode on the KAT front panel. 3. When the KAT500 sees a transition from split on to split off then go into "normal" (non Split) mode. The main reason I am using the tuner is because of a compromise antenna. If the antenna was flat enough across the band I wouldn't even engage it. In my specific situation there is also at KPA500 connected, so the way that the KAT500 works today will result in the KAT inhibiting the KPA while it retunes/recalls. Although fast, I suspect that the amp is not engaged initially when I send (speak) my call sign in the pile. On very rare occasions there is also a KPA VSWR Fault. While probably not an issue, the amount of relay chatter in very short period of time between fast RX/TX/RX transitions is a bit unsettling. 73, Cliff K3LL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Sunday, November 15, 2015 10:04 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KAT500 Re-Tuning On Sat,11/14/2015 8:37 PM, Byron Peebles wrote: > I will put the antenna analyzer on it tomorrow and make sure it's > still solid after all this wind. Other suggestions. First, put it on bypass and see what the SWR indication is. If it's reasonable, go to MAN mode, force a tuning (put K3 in TUN mode) and let it tune. Carefully check the entire coax path between K3 and the antenna. All connectors should be finger tight, then tighten with gas pliers. Any indication that the coax is wet? Moisture entering anywhere along the run will usually migrate all the way down to the lowest point. Open connectors to see if there's any moisture. A good way to test is to use a tissue or paper towel as a probe. If you have TDR capability, look at the feedline for any discontinuities. You should see connectors, the antenna, and any switching between the antenna and your test point. Most vector analyzers can do TDR. If you don't have one of them, ask around your ham neighbors to borrow one (and ask them to help you do the measurement). 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 cf at cfcorp.com ______________________________________________________________ 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 fcady at montana.edu From jackbrindle at me.com Sun Nov 15 19:27:58 2015 From: jackbrindle at me.com (Jack Brindle) Date: Sun, 15 Nov 2015 16:27:58 -0800 Subject: [Elecraft] KPA500 RX Attenuation and TX Without Amp Key In-Reply-To: References: Message-ID: Mark; Recheck the ribbon cable connections in the amplifier.

All you need to do is select the antenna of interest from the Front Panel - no computer required. KAT500 Utility can make the setup of the various bands and antennas easier than doing it manually. That does require a computer, but once set up, no computer is required. You can setup the KAT500 without the use of KAT500 Utility, but it will take longer and require more mechanical steps. The Utility program can be downloaded from the Elecraft website - it does not come already installed with the KAT500. 73, Don W3FPR On 11/14/2015 10:09 PM, Robert Clark wrote: > Doesn't the KAT500 come with a utility program already installed? > And...can the unit be operated without a computer connection? > > ______________________________________________________________ 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 g4gnx at theatreorgans.co.uk From vr2xmc at yahoo.com.hk Sun Nov 15 20:30:50 2015 From: vr2xmc at yahoo.com.hk (Johnny Siu) Date: Mon, 16 Nov 2015 01:30:50 +0000 (UTC) Subject: [Elecraft] Status of KIO3B for Elecraft K3 - also DSP board In-Reply-To: <20D7DA18-4DA1-4C46-8217-5A7417C6DA30@nobis.net> References: <20D7DA18-4DA1-4C46-8217-5A7417C6DA30@nobis.net> Message-ID: <1407357624.4219470.1447637450799.JavaMail.yahoo@mail.yahoo.com> Hello Bob, Oh, I would also like to know when the new DSP board (with improved audio) will be available for K3 upgrade.

Not all power supplies are created equal ... in a host of ways ... but a really solid one can make a big difference in a number of ways.

You do not mention which rig you are using to drive the KPA500 or how you have the transmit switching configured. I bought a new TS590SG some months ago and set it up using the solid state switching which on the face of it is exactly the same as the TS990 which works perfectly with the KPA500. However, with the TS590SG, all it did was exactly as you describe. What is happening is that the transmit switching arrangement - whatever it is that you are using - puts the KPA500 permanently in a transmit state and then it works normally to amplify the signal when you key the rig (or horror of horrors speak into the microphone. If by any chance you are using a TS590SG you can test the amplifier for correct operation by changing to the relay switching rather than solid state. In my case, the matter was resolved after some liaison between the Australian Kenwood Service Centre and Elecraft determined that the pull up or pull down resistor ( I can't remember which it was) in the TS590SG was too low such that it put the KPA500 permanently in a transmit state. Kenwood simply increased the resistor appropriately and now it works fine just like the TS990. I hope that might point you in the right direction. 73 Barry VK2BJ On 16 November 2015 at 07:24, Mark Goldberg wrote: > I will contact Elecraft tomorrow, but posting in case someone > recognizes the symptoms. > > I just put together a new KPA500 kit.

(I use an external transverter). As I need to be able to switch between Data (WSJT)and SSB/CW frequently and didn't want to be constantly plugging and unplugging mic and speaker leads here is what I did: For the receive audio I used a Behringer HA400 4 channel stereo headphone amplifier which feeds stereo headset, powered stereo speakers and soundcard. Problem solved. I can leave the KX3 audio gain at a fixed level and control individual levels on the headphone amplifier. I can monitor receive audio while on Data etc. For transmit audio I built a switch box which has a switch to change from Soundcard (Data) or Microphone ( switching audio and PTT) . I also have a switch to choose either headset boom microphone or another desk (or hand) microphone. I have a footswitch for PTT when using the headset boom mic. It was half a day's work to make this neat plastic box with a couple of switches and 3.5mm sockets. A nice feature of having a mic/soundcard switchbox is that when in Mic position there is no possibility that when I boot up the computer that the PTT of the transceiver gets pulsed on and off. It would have been great is there had been extra switching and sockets for doing this in the KX3, but I realise that it is a portable radio and there have to be some compromises to make it so. I am just amazed what Elecraft have been able to squeeze into it. 73 David Anderson GM4JJJ > On 14 Nov 2015, at 12:58, Ken Alexander wrote: > > Myself, I would prefer not to lose my 2m capability.

I'm very happy with the external soundcard I use with my notebook computer. However, I won't ever buy another transceiver that doesn't have a dedicated Data jack, even if it does say Elecraft on the front. I find it a pain to be constantly unplugging cables and inserting new ones each time I change modes. I'm afraid of wearing out the 3.5mm jacks on the KX3 with all the inserting in and removing of plugs.

In the K3 the roofing filter is in the analog 8 MHz IF and the DSP filter is program code working on the number soup somewhere after the RX analog to digital signal conversion. The only "interaction" possible is the sum of the two pass band losses at a given frequency for the two filter bandwidths chosen. Speaking particularly of CW contest operation there is a good deal useful to be said for aligning the -15 dB points on both slopes to create the narrowest -30 dB points when the actual roofing and DSP bandwidths are set the same. One might term this a *desired maximum* "interaction" (sum) of the two filters. This results in operating bandwidths of 450 and 350 Hz using the "400" and "250" filters respectively for the most abrupt combined skirts. When running (calling CQ and listening for answers) in a contest one needs to listen up and down a little because we get answers to our CQ's not zero beat. We need to hear that bandwidth well and then have the combined filter skirts drop off as steeply as possible beyond. This is because as routinely experienced the next running station up or down frequency can be obscenely loud. The combination of roofing and DSP filter skirts is the only defense against loud adjacent signals which are routinely up and down 500 Hz and as close as 300 Hz. When there are nearby clicky signals, the sharp combined skirt drop results in a reduced amplitude sharper click which the K3 noise blanker handles well set to DSP 2-7 and IF off. These very positive K3 behaviors are very well known among serious CW contest operators and one of the reasons for its high popularity in this group. 73, Guy K2AV On Monday, November 16, 2015, wrote: > > > Although Elecraft has documented the response curves of their 5 and 8 > pole roofing filters, I can't find any plots of their narrow DSP CW > filters, like the 50, 100, 150 or 200 hz filters.

I'm hoping that the constant slope you described is not the way the DSP filters are implemented, because that would mean the 50hz filter has a 5.625:1 shape factor, the the 100hz filter has a 5:1 shape factor, the 200 hz filter has a 3:1 shape factor and the 400hz filter would have a 2:1 shape factor. To achieve better than 2:1 shape factor at 30dB per 100hz, the width of the DSP filter would need to exceed 400hz. I wonder if anyone has put their K3 or K3S in the 1 hz tuning mode with a signal generator and ploted out the approximate response curves using the S meter. It's a rather crude way to do it, but in the absence of more accurate test gear it will give some idea of the shape factor of the DSP filters. I will be ordering a K3S today and will ask Elecraft if they have plots for the 50, 100, 150, and 200 hz DSP filters. If not, I will get the little signal generator and report my findings on the reflector. If anyone reading this thread has plotted out the 50, 100, 150, or 200 hz DSP filter response curves, please let me know.

I understand your rationale for aligning IF and DSP filters for additional out-of-passband rejection in crowded contest conditions. My concern stems from using IF shift to move the DSP filter within the roofing filter passband. The Elecraft rep I spoke to last week told me that the 8 Mhz IF roofing filter and the DSP filters do not track. The roofing filter is fixed and will present a fixed bandwidth in which the DSP filter can operate. Therefore, there will be an interaction between the two filters, the fixed roofing filter, and the DSP filter which can be moved higher or lower with the IF Shift control. If the roofing filter and the DSP filter have the same bandwidth, the interaction between the filter skirts creates a high cut or low cut condition depending upon the direction of the IF shift. If the IF can be shifted enough, a stop-band condition occurs and all signals disappear. I am primarily a "search and pounce" contester, but I can appreciate your desire to have the sharpest combined filter skirts to keep the adjacent run station from getting into your bandpass. However, my limited experience with "run" contesting revealed that extremely sharp filters are a double-edged sword because of the inability to hear off-frequency callers. In fact, I think there is an option in the K3S menu system that provides for higher shape factor DSP filters in order to allow off-frequency caller to be heard. In the S&P contest mode, I also want very sharp DSP filters, but I want them to exist within a wider roofing filter bandwidth so that I can use the IF shift to discriminate between signals in that passband. If my DSP filter and my roofing filter are about the same bandwidth, I can't use the IF shift effectively because its filter skirts will interact with the roofing filter skirts and cause an undesirable high cut or low cut resultant filter response, or worse, the dreaded stop-band condition. Another consequence of cascading a roofing filter and a DSP filter of the same bandwidth in a run contest mode is that the only recourse to hear an off-frequency caller is to engage the RIT (since engaging IF shift with result in the above stated undesirable resultant filter response curves). When I am in "run" contest mode, especially in very crowded conditions, using RIT changes the pitch of every station that is audible, and I just don't like to lose my awareness of where each station is. I much prefer to use the IF shift to "highlight" the caller I want to contact without changing the pitch of every single station. Therefore, I hope you can see why I would not want to have a roofing filter that is too narrow for the DSP filter that I plan two use in combination with IF shift. Since I like to use the 100 hz DSP filter bandwidth, I would not chose the 200hz roofing filter as an option because it would severely limit the amount of IF shift that I could use with a 100hz DSP filter. If I were not a fan of IF shift, I would do what you are doing, cascade the 200hz roofing filter and use the 100 or 200 hz DSP filter. In summary, I am hoping that the DSP filters have very steep skirts to maximize the IF shift that can be used before the DSP filter skirts interact with the roofing filter skirts. If you have any data on the narrow DSP filter plots, please let me know.

Both sets of S meter readings below start with the K3 in CW mode tuned to 3550.000 with the S meter reading S9+40 from a 3550.0 signal supplied by an HP8640B. As you suggested, I then tuned the K3 away from the signal from the generator. 400 Hz filter in "normal" configuration (400 Hz DSP also): +40 = 3550.000 +35 = 3550.134 +30 = 3550.166 +25 = 3550.177 +20 = 3550.182 +15 = 3550.185 +10 = 3550.190 +5 = 3550.195 S9 = 3550.198 S8 = 3550.204 S7 = 3550.208 S6 = 3550.213 S5 = 3550.224 400 Hz filter with DSP narrowed to 200 Hz: +40 = 3550.000 +35 = 3550.068 +30 = 3550.080 +25 = 3550.094 +20 = 3550.104 +15 = 3550.112 +10 = 3550.120 +5 = 3550.126 S9 = 3550.130 S8 = 3550.138 S7 = 3550.142 S6 = 3550.145 S5 = 3550.150 I only had time this morning to measure two filter settings on one slope of each filter. I'll let you plot the data. I hope you find this information useful until you get some better information. 73, Bill - NA5DX [Elecraft] K3S DSP filter plots *charles at k5ua.com*charles at k5ua.com /Mon Nov 16 10:59:13 EST 2015/ * Previous message (by thread):[Elecraft] K3S DSP filter plots * Next message (by thread):[Elecraft] K3S DSP filter plots * *Messages sorted by:*[ date ] [ thread ] [ subject ] [ author ] ------------------------------------------------------------------------ Thanks for the reply Joe. I'm hoping that the constant slope you described is not the way the DSP filters are implemented, because that would mean the 50hz filter has a 5.625:1 shape factor, the the 100hz filter has a 5:1 shape factor, the 200 hz filter has a 3:1 shape factor and the 400hz filter would have a 2:1 shape factor. To achieve better than 2:1 shape factor at 30dB per 100hz, the width of the DSP filter would need to exceed 400hz. I wonder if anyone has put their K3 or K3S in the 1 hz tuning mode with a signal generator and ploted out the approximate response curves using the S meter. It's a rather crude way to do it, but in the absence of more accurate test gear it will give some idea of the shape factor of the DSP filters. I will be ordering a K3S today and will ask Elecraft if they have plots for the 50, 100, 150, and 200 hz DSP filters. If not, I will get the little signal generator and report my findings on the reflector. If anyone reading this thread has plotted out the 50, 100, 150, or 200 hz DSP filter response curves, please let me know.

This will give me a pretty good idea of the shape factor of the 200hz DSP filter. I just ordered a K3S, and the technician that helped me with some of my questions said that no one has ever asked him about the shape factor of the DSP filters. So I guess we are breaking new ground with this thread. The definition of a filter's shape factor is the width of the filter between its -6 dB points and it's -60 dB points. Since we are using an S-meter to determine signal strength as we move away from the signal's center frequency, it is a rough approximation of true signal strength. We are also going to assume that the K3 S-meter is 6 dB per S-unit all the way from S5 to S9+40dB. I am also assuming that these reading would be symmetrical if you had measured the lower side of the filter skirts. Given those assumptions and their limitations, let's see if we can determine the shape factor of the two filter scenario's you measured. Data Set 1. Cascading the DSP 400hz filter with the 400hz roofing filter gave a -6 dB point approximately 140hz higher than the center frequency (extrapolating 1 dB down from the -5 dB frequency of +134hz). That would make the width of the filter at the -6 dB points approx 280 hz. The S6 level would represent a drop of 58 dB from the center of the filter (+40 dB + 18dB), so the -60 dB frequency would occur at approx +216hz from the center frequency. That would make the -60 dB width of the filter (216hz + 216hz) = 432hz. So the shape factor of this cascaded 400hz roofing filter and 400 hz DSP filter would be 432hz/280hz = 1.52. Notice that this is a better shape factor than the roofing filter alone which has a Elecraft documented shape factor of 2.1. Data Set 2. The DSP filter has been narrowed to 200 hz in this scenario and still cascaded with the 400hz roofing filter. This should give the opportunity to dtermine the shape factor of the DSP filter itself since it is entirely contained within the passband of the wider 400hz roofing filter. The -6 dB point of the DSP filter is approx +70 from the center frequency ( extrapolating again 1 dB down from the -5 dB frequency of +68hz). That would make the filter width at the -6 dB points (70hz + 70hz) = 140hz. As in the first scenario, the S6 level would represent a drop of 58 dB from the center of the filter (+40 dB + 18dB), so the -60 dB frequency would occur at approx +146hz from the center frequency. That would make the -60 dB width of the filter (146hz + 146hz) = 292hz. So the shape factor of the 200hz DSP filter is 292hz/140hz = 2.08. Based upon the data provided, the shape factor of the DSP filter is virtually identical to the shape factor of the roofing filter. I'm not surprised that cascading two 400hz filters with identical shape factors create a resultant filter with a better shape factor than either filter alone. I ordered the XG3 with my K3S, so I will obtain data for the 50, 100, and 150 hz DSP filters inside of the 400hz roofing filters. I will also obtain data for the 200hz DSP filter inside of the 2800hz SSB filter. The data should be identical to the 200hz filter inside of the 400hz roofing filter. Thanks to all that replied to my inquiry.

The IF shift is normally used to reduce interference from an "offending station". That along with the Width control can isolate a single station with ease and with the 50 Hz minimum DSP bandwidth, operation in a crowded band segment can actually be a pleasure - unless an extra strong signal gets past the roofing filter passband and activates the hardware AGC. When you get your K3S, give it a try and I think you will find the use of RIT to be more effective. Of course, if you ordered the KRX3, you can always go to SPLIT and eliminate the need for using RIT. Split will cover a much greater range than RIT. The KRX3 is not required to operate SPLIT, but if you want to dynamically listen to your transmit frequency and the desired signal at the same time, the KRX3 is the only way to do that. Without the KRX3, you can use the REV button to temporarily listen to your transmit frequency, but you will not hear both frequencies at the same time with the REV button. Yes, I realize this is a bit different than the discussion of filter shapes and the interaction of the roofing filter with the DSP filtering. If it is not relevant, then please ignore my comment. 73, Don W3FPR On 11/16/2015 12:35 PM, charles at k5ua.com wrote: > > > Thanks for the reply Guy. > > I understand your rationale for aligning IF and DSP filters for > additional out-of-passband rejection in crowded contest conditions. > > My concern stems from using IF shift to move the DSP filter within the > roofing filter passband.

I have done measurements using a broadband noise for the source and measured spectrum of the recovered audio. Of course as the DSP BW is changed the recovered audio changes accordingly. The definition at 6 dB and 60 dB can be attained. I doubt the S meter method is more than an approximation of values unless all values are related to S units @ 6 dB per S unit or the value in dBv which can be obtained from the detector via the Config Menu.. Perhaps Wayne is better qualified to define the performance of the DSP filter system, usually limited by the number of poles and is done mathematically. This of course would be somewhat different than the recovered audio method. Yet, my preference is recovered audio in as much as that's what we hear. 73 Bob, K4TAX K3S s/n 10163 On 11/16/2015 6:00 PM, Don Wilhelm wrote: > Charles, > > I believe most operators use the RIT control rather than IF Shift to > tune for off frequency stations. > The IF shift is normally used to reduce interference from an > "offending station".

For CW I use 0.1 kHz. 2.5kHz is typical for FM stations, but too wide for SSB or CW. To me, it is just a quick way of scanning through the band. If your expectations are more than that, then submit your request for an additional firmware upgrade. If the coarse tuning does not land you on a 'netted' frequency, a slight adjustment of the VFO A knob will bring in the occasional 'off frequency' station. I regard it as a way of scanning the band with the knobs and do not mind fine tuning any station of interest with the VFO A knob. YMMV. I prefer that to using computer control of the frequency although I am of the 'old school', and old habits die hard. 73, Don W3FPR On 11/16/2015 8:36 PM, Peter Pauly wrote: > The Rounding YES/NO doesn't seem to have any effect.

It is all about the DSP system. Lyle performed an experimental test of a 500 Hz DSP filter inside a 2.8 KHz roofing filter, so the DSP filter was the determinant factor. Here is his email again: http://marc.info/?l=elecraft&m=120716404727940&w=2 The inference I drew from Lyle's response is: DSP 60 dB BW = DSP Setting + 300 Hz. You can see that DSP "shape factor" varies with the DSP setting, so it is easier to remember the DSP+300 formula. Dave Hachadorian, K6LL Yuma, AZ .

It's worth mentioning that a similar thing happens with analog crystal filters. The shape factor gets worse the narrower the filter bandwidth.

I believe, at least at some bandwidths, the K3 offers both IIR and FIR (infinite and finite impulse response filters). For data modes, FIR filters are better, as they are linear phase filters. The skirt slope of such a filter is directly proportional to the number of taps used in the filter (the number of old samples added together). Having a large number of taps increases the processing load on the DSP, so will be limited by the need to work within the processing power of the DSP device. Also longer filters mean larger group delays. IIR's have variable group delays and ring, but can produce responses that could only be approximated by very long FIR filters. Incidentally, merging the roofing and DSP filter edges is likely to compromise the good group delay, and lack of ringing, characteristics of the FIR filters. -- David Woolley Owner K2 06123 On 16/11/15 15:59, charles at k5ua.com wrote: > I'm hoping that the constant slope you described is not the way the DSP > filters are implemented, because that would mean the 50hz filter has a > 5.625:1 shape factor, the the 100hz filter has a 5:1 shape factor, the > 200 hz filter has a 3:1 shape factor and the 400hz filter would have a > 2:1 shape factor.

When I want to go fast, I sometimes change modes to get a faster skew. What I would like in this are is to have the K3 adopt the KX3's behavior of zeroing the low order digits of the frequency. Enough radios make it easy to transmit on these frequencies that it is useful to easily tune them.

I was having problems on the low end of 6 meters. VSWR was all over the place! The K3 would always measure a 1.2 :1, the KPA500 measured 1.5 to one and the KAT500 wouldn't match my 6 meter beam. I agree that there was a problem with my Hygain 66DX6 but even on my Bird dummy load the SWR measurements were off. On Sunday, I re-tuned my 6 meter beam. I was able to match the antenna but the VSWR on the K3 was still all over the map. I remember when I was building the KPA500 that there was a 4" twisted wire from the PA board to the RF out jack. A short twisted wire as a transmission line on the HF bands is probably OK but On 6 meters, the inductance in twisted wire, I'm sure, will exhibit loss. I replace it the wire with a 4" length of RG58U. Now all 3 SWR readings agree and the VSWR is 1.1:1.

Normally twisted pair makes a very effective and self shielding transmission line, even at 6 meters. The characteristic impedance does depend on the diameter of the conductors and the thickness of the insulation separating the two conductors. I am glad that you had success with your RG-58 substitution, but I believe there was some other condition present that your substitution corrected. 73, Don W3FPR On 11/17/2015 5:55 PM, wa9fvp wrote: > I remember when I was building the KPA500 that there was a 4" twisted wire > from the PA board to the RF out jack.

I also purchased the Hampod, refered to in an earlier post. Again I've only been using the hampod for a matter of days, but first impressions are it's an amazing peice of kit, providing spoken access to vertually all of the functions of the K3s. The Hampod is a stand alone unit which connects to the serial port on the rig. More info can be found at www.hampod.com Like I said, I'm only beginning to become acquainted with both the K3s and hampod, so can't really offer much more information. However if You're thinking of a k3s or kx3, I reckon the hampod is certainly worth investagation. Btw, the JJ radio software I think provides some degree of speech access to Elecraft equipment, but of course this requires connection to a PC. Hope this is of some help.

I have had my K3 doing rounding for some time now, but I forgot just how it was done - the menu listing told me how to do it. I would encourage everyone to study the menu listing rather than just the text of the operating manual.

Because the input circuit offered a j0 match, I concluded that the problem had to be associated with the amplifiers output. In bypass mode, the bypass relay connected the input directly to the output. I was confident that the Elecraft did their homework and the PA, PC board design was correct and offered a j0 match from the input to the output. I think the problem is on the ground side of the twisted pair. There's enough stray inductance to introduce loss between the PA board ground and the connector ground. There's no direct connection from the wire ground pin to the chassis. If my memory serves me, the only ground points on the PA board are on the corners of the board. On the input connection, there's a mini coax jumper. Before changing it, I untwisted the wire about 4 turns and the VSWR went from 1.2:1 to 1.4:1. I twisted the wire tighter and it went back to the original measurement. When I worked at Argonne National labs, in the Avanced Photon Source RF group, we were working with 350 MHz, 1 megawatt klystrons. We learned all about ground loops the hard way. jack WA9FVP ----- Jack WA9FVP Sent from my TRS-80 :-) -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-KPA500-VSWR-on-6m-tp7610474p7610483.html Sent from the Elecraft mailing list archive at Nabble.com.

I am now ordering the parts which in some cases gets quantity discounts and/or reduced shipping per unit. The next opening for taking orders will be at 0000utc on Nov. 23 (which is Sunday evening in the US). Orders will be taken but no payment will accepted at this time. Production on this group of orders will begin in Jan. 2016 and I will contact those ordering the last week of December for payment of their order. Orders will be filled in order of order received and paid. I probably will cut off the next group of orders at five as that is about what I can produce in a month and no point in someone waiting longer. Any orders received next week beyond 5 will be retained and contacted near end of Jan. This batch ordering method will allow me to keep parts costs minimized and pass the savings to you. Currently the price is $299.00 plus $18 US ship&ins for kits and $369.00 plus $18 US ship&ins fully assembled and tested . International shipping& insurance is more (eg: to England $69.95). Shipping is via medium sized Priority Mail carton. There may be some adjustment in price after I see what the initial parts costs total. The amplifiers are W6PQL design pc boards. Input drive 1-10w with 80w output (linear). 12v dc power. Internal TR relay bypasses for Rx. SSB/FM time constant switch and RF output LED bar meter. 4-inch fan on 5-3/8 by 8 inch heat sink.

Toggling twice brings you back to the mode you were first in. I set up the F4 button to accomplish this toggle. So a quick double press of F4 gets me centered. There was a side benefit.

Toggling twice brings you back to the mode you were first in. I set up the F4 button to accomplish this toggle. So a quick double press of F4 gets me centered. There was a side benefit.

The K2/100 also has a grounding screw. With the KX3, you can put a ring terminal under one of the thumbscrews. Which piece of Elecraft gear do you have that is lacking such a screw?

In earlier times, the "Collins Standard" was 6 dB/S-unit and 50 uv = S9. My 75S3 came in at 53 uv for S9, and pretty much held to the 6 dB/S-unit below that. Not so much above S9 With my service monitor feeding my K3, it is exactly 50 uv = S9 because I set it for that. It's a little hard to tell on the bar graph S-meter, but it seems to be about 5 dB/S-unit below S9. It also seems to be about 5 dB/S-unit above S9 [i.e. quite linear, in the logarithmic sense :-)]. I've often wondered why S-meters go above S9 which should be about the strongest signal you ever receive and thus would be full scale. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 11/16/2015 10:09 PM, Vic Rosenthal wrote: > I believe 5 dB is the correct number.

In-Reply-To: References: Message-ID: <564CEEFF.2020204@sonic.net> Of course in fixed-tune mode the screen always displays the same fixed frequency range -- as you tune the K3 VFO, the cursor moves across the screen while the displayed frequency range remains the same. In tracking mode, you can offset VFO A to the left side of the display using the CENTER control. (You have to have enabled the CENTER control using the CenterEn menu item.) Once you do that, the VFO A cursor will remain at the same position on the display as you tune the VFO. If you have the display set up to show (let's say) -1 kHz to +9 kHz from the VFO frequency, it will continue to do so. Alan On 11/18/2015 12:36 PM, Mike Reublin NF4L wrote: > Span is set at 10.

Just hold the CENTER button and turn the SELECT knob until the VFO-A green cursor is at the far left. It will stay put as long as you don't move VFO-A on the K3. The VFO-B (magenta) cursor (and the split red cursor) will move as you tune the VFO-B knob on the K3. If you also want to use the A and B markers they will follow the select knob on the P3. 73, Mike K2MK Mike Reublin NF4L wrote > Span is set at 10.

If the piece of equipment does not provide such, then one will need to be added. Be sure to remove the paint from both inside and outside of the area where one drills the hole. A #8 screw, add internal tooth lock washer and #8 nut and this will be adequate. Be mindful when drilling from the outside to the inside that the bit does not suddenly grap and drag the rotating bit into the inside causing damage to whatever it may strike. I prefer removing the rear panel and use a drill press for any drilling and de-burring. That way there's no chance of metal shavings getting inside. 73 Bob, K4TAX On 11/18/2015 2:45 PM, Frank wrote: > I am a firm believer in a good ground for ANY transceiver, but need advice: > Where would be the best location (internal OR external ) to install a small bolt for attaching a ground rather than having to us a ?clip? attached to a ground. > > Thanks, Frank Sharit, W6DHN From rmcgraw at blomand.net Wed Nov 18 18:42:41 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Wed, 18 Nov 2015 17:42:41 -0600 Subject: [Elecraft] About to fire up the k3s for the 1st time In-Reply-To: References: Message-ID: <564D0CF1.5000103@blomand.net> Yep, it's in the manual.

My impression is that the K3 and KX3 use the -73 dBm reference even on 6m. Is that right? What about with transverters - does one have gain calibration? Obligatory Elecraft comment: it would be really nice to be able just show signal strength in dBm.

The transverters typically have 10 to 15 dB of gain as measured from input to output in receive. It is nice that I can do frequency calibration via the K3S. This corrects minor errors existing in the transverter conversion oscillator. 73 Bob, K4TAX On 11/18/2015 7:18 PM, Greg Troxel wrote: > My impression is that the K3 and KX3 use the -73 dBm reference even on > 6m.

One adjusted the volume for a good listening level and read the S-unit reading off of where the volume control pointed! The impetus for Collins was very pragmatic. Production test techs on the assembly line needed a specific reference to determine that the receiver and S-meter were working as expected. That meant an S-number corresponding to a certain RF level at the antenna input. My point is that there was nothing "sacred" about that decision. And keep in mind that back then the High Frequencies (H.F.) stopped at 30 MHz. Anything above 30 MHz, including the 10 meter Amateur band, was officially Ultra High Frequency (UHF). All the focus of most Hams was on H.F. But most Hams simply gave signal reports based on how the signal sounded. Personally I have always appreciated the QSA system we used on commercial radiotelegraph circuits: QSA 5 was very good and QSA 1 a barely perceptible signal. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob McGraw - K4TAX Sent: Wednesday, November 18, 2015 3:46 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S DSP Filter Plots The original S meter development for HF radios was done by Art Collins.

One of the best ways to familiarize yourself with the K2 and its options is to open the manual and imagine yourself building it, and particularly concentrating on the the Alignment and Test sections. You probably don't have to make all the adjustments, but you can run through the exercises that involve turning the knobs and pressing buttons. Repeat for the KPA100 and the KAT100, and then follow up by doing the same thing with the manual for each of your installed options. By the time you finish that process, you should be familiar with the operation of your K2 Twins. Hopefully the prior owner provided you with the control cable that plugs between the base K2 KIO2 module and either the KPA100 or KAT100 DE-9 connector. If you do not have that cable, the KAT100 manual contains the diagram for the cable that you need to build. 73, Don W3FPR On 11/19/2015 9:57 AM, Alan KB7MBI via Elecraft wrote: > A few months ago I purchased a K2/100 "twins".

If I tune higher with B or B marker, I hit 14.027.5 a little to the right of the physical center of the screen. So is there a way to have that almost full screen from the A cursor on the left edge to the right side of the screen cover 5 KHz? It sure would make it easier to find the sweet spot in the pileup. 73, Mike NF4L > On Nov 18, 2015, at 4:34 PM, Alan wrote: > > Of course in fixed-tune mode the screen always displays the same fixed frequency range -- as you tune the K3 VFO, the cursor moves across the screen while the displayed frequency range remains the same. > > In tracking mode, you can offset VFO A to the left side of the display using the CENTER control.

In tracking mode, if you set the span to 5 kHz and adjust the CENTER control until the VFO A cursor is right at the left edge of the screen, then it will display from the VFO frequency to 5 kHz above it. As you tune the VFO you will always see 5 kHz just above the VFO frequency. 73, Alan N1AL From rmcgraw at blomand.net Thu Nov 19 14:28:03 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Thu, 19 Nov 2015 13:28:03 -0600 Subject: [Elecraft] No transmit on 12m in split??

The K3 *can* transmit cross-mode if you set it up as indicated on page 36 of the manual. With cross-mode operation possible, it is not desirable to set all parameters of VFO B to the same as VFO A unless the operator intends to do exactly that. Thus the double tap is required. 73, Don W3FPR On 11/19/2015 2:41 PM, Larry Gauthier (K8UT) wrote: > Tom, > > When you tap/hold the button, watch the K3 display to see if > you get the error message "SPL N/A" (Split Not Available ?).

Message-ID: Pete: you replied with this...I find that WSJT-X works better for me than JT65-HF and is written by Joe Taylor (K1JT) himself. I see this at his website: WSJT-X implements JT9, a new mode designed especially for the LF, MF, and HF bands, as well as the popular mode JT65. Both modes were designed for making reliable, confirmed QSOs under extreme weak-signal conditions. They use nearly identical message structure and source encoding. And this...A 2 kHz slice of spectrum is essentially full when occupied by ten JT65 signals. As many as 100 JT9 signals can fit into the same space, without overlap. (more efficient is a good thing). Are there like or similar numbers of JT9 ops as there are JT65 ops? Is JT9 rockin' the lower bands - 160, 80 and 40??? I'm "axin'" 'cuz I'm about to load JT65 s/w and get it runnin' 'tween my Microsoft Surface Pro and my KX3 -- I'm not averse to loading WSJT-X and getting a friend of mine to configure he s/w and get it running.....might be more beneficial to go with WSJT-X as it has a "bi-lingual" operating mode so you can switch between the two....is WSJT-X any more difficult to set up or, if one is fairly familiar with the "old JT65"? 72 de Jim Rodenkirch K9JWV From frantz at pwpconsult.com Thu Nov 19 19:06:45 2015 From: frantz at pwpconsult.com (Bill Frantz) Date: Thu, 19 Nov 2015 16:06:45 -0800 Subject: [Elecraft] Get the kids off the street - making my move!

There is quite a bit of activity between 14.070 and 14.073 on the 20 meter band. You can use the radio's VOX for keying, so you can avoid having to worry about a keying interface for the start. The PSK signal is symmetric, so you should be able to work and copy other stations without worrying about USB vs. LSB issues. When you get PSK running, you know your computer can communicate with your radio both ways. Then when you try other modes, and they don't work, you start debugging with a large number of things that do work. 73 Bill AE6JV On 11/19/15 at 8:57 AM, ab7mp at arrl.net (Mark) wrote: >After being CW only for over 2 decades, I've made the decision >(now that I have a K3S/100) to move into digital comms.

I did install WSJT-X and see a lot of JT-65 but no JT-9 yet. Started working through configs for PSK31 with WinWarbler and think I'm about ready. I'm going to spend some time looking at the macros so I don't have to think too much when I "stick my big toe in the pond" - maybe tomorrow. I want to spend some time copying to catch the rhythm of the operating and get a feel for what would be expected in a QSO. Actually, that's what makes JT65 look appealing - very canned action for the most part. Just don't get to know the other op as well.

Although I use the K3S, there is only one cable required between the computer and the radio. It handles the audio and the PTT and CAT commands. No interface required. I do use a SignaLink USB with one of my other radios. For software, FLDIGI is free, and has the required configuration files for the KX3 and K3/K3S radios. Plus the MACRO's are easy to configure for your personal liking and it creates a log which can be uploaded to your favorite logging program. I finally figured out that the more software applications I have running to do different things, the more issues I have to resolve. Some software systems will easily hand shake and work with others, while others turn into more of a fist fight. I typically only run one application and let it do all my radio chores. 73 Bob, K4TAX K3S s/n 10163 On 11/19/2015 6:06 PM, Bill Frantz wrote: > I generally recommend people start in the digital world with PSK31. > There is quite a bit of activity between 14.070 and 14.073 on the 20 > meter band.

I find most hams believe they can operate any old radio and don't need to read the stinkin' manual. HA! As to operation, your QTH & noise, your antennas, your selection of optional filters and options, choice of mike and key or paddle will make a difference in the way the radio is configured or set to run specifically for you. The way it comes from the factory is about 90% of what you'll need. You should have it on the air and getting good reports in 1 hour or less. Every one will have or suggest individual tweaks or preferences. Just keep it simple, change what you need to change and resist tweaking everything just because someone said such and such needs to be changed. If one makes a change, I believe they should have a very good reason for making a change and know what to expect after they make the change. Otherwise, put it back to the value(s) it was. The K3S is far from the "cookie cutter" radios of Kenwood, ICOM, Yaesu, Tentec and others. It doesn't operate like those. I know, I transitioned from one of those competitive models.

Message-ID: <1jts4bhfe41h3c6ffngron0a8e10dh4e8q@4ax.com> > Is JT9 rockin' the lower bands - 160, 80 and 40??? Can't answer that, but JT9g is going strong on 10 meters (28.148). It's a high speed version of JT9 used on both meteor scatter and Es. A slightly higher bandwidth version, JT9h, is used on 6 meters, and is quite popular (50.280). Currently, there's lots of activity daily, but we're needing to spread the word to DX folks to tune up that high. Transmission lengths available are 5 second, 10 second, 15 seconds, and 30 seconds. When the band is up, a full exchange can be done using 5 second tx/rx cycles in less than one minute. Extending to 15 second cycles takes appropriately longer. Semi automatic completion is used most of the time. Typically, a full QSO will be done before you can finish entering it in the log! :) 15 second exchanges are default, but can be extended when sigs are quite weak.

Each of us has our favorite settings that have been derived from our own personal desires and operating styles. However, the K3 (and K3S) can be used "out of the box" with its default settings. So operate it for a while with those defaults. Look through the options presented in the manual to get an idea about how the K3S can be configured and you should see just how versatile it can be in configuring it for your personal preferences. Yes, you can ask others for their settings, but since those preferences vary from operator to operator, you are just as good using the defaults initially. Over some operating time along with a review of the menu settings, you should be able to customize the K3S to your desires. Use it as-is for a while, and listen to the settings that others use, but more importantly, listen to "why" they use those settings and decide whether those reasons fit you operating preferences. We all like to think our particular choices are "the best", but they may not apply to all. If those choices were to apply to all, then they would be present in the default settings. Use the defaults and then vary from them as you see fit after some operating experience with the K3S. 73, Don W3FPR On 11/19/2015 8:12 PM, Jerry wrote: > The xyl always tells me that . . .

In the process, several calibration settings are also set to the factory standard default values - but those values may not be the ones that exactly match your K3S - there are calibration settings that are unique to each K3 (K3S). The process for EEINIT (Parameter Initialization) can be found on page 66 of the manual. If you have saved a configuration using K3Utility prior to encountering any problems, you can restore that configuration and the calibration settings will also be restored. If you have not saved a configuration when the K3S was operating properly, you will have to go through the calibration procedures after doing an EEINIT. Bottom line, save a configuration file on your computer when you get your K3S and again after making any significant changes. In case of difficulty, you can then try an EEINIT and reload the last working configuration and you should be "good to go". 73, Don W3FPR On 11/19/2015 8:46 PM, Tristani Ramon wrote: > Is there a button or combination of buttons/actions that can re-set the K3 to the ?Factory Configuration??

Yes, you will have to set the software to activate PTT with either DTR or RTS and set the K3 menu accordingly. The microphone will still be live during the time that PTT is active, but that is less severe than using VOX where room sounds will activate transmit. The only other cure is to use a microphone that is muted until its own PTT switch is activated (usually mobile microphones). Most amateur microphones are wired "live" to allow the use of VOX, but a few open the AF line until the PTT switch on the microphone is activated. Your exact microphone wiring diagram may present clues at how the microphone can be configured. Some microphones do not give you a choice. 73, Don W3FPR On 11/19/2015 9:25 PM, Bill Rogers W3UL wrote: > I'm all set for Sweepstakes SSB with N1MM+ and a K3.

Why do I say everyone? Simple, there are so many menu choices/settings that can be made - that the rig becomes customized to each individual. In other words, the K3 offers so much user versatility that it amounts to thousands of individual K3 rigs that are all different. I doubt if there are too many out there that are identical. The K3 is a tinkering ham's dream. So many changes can be made - none with a soldering iron or tuning wand in hand. Saving settings to computer files is a great idea, however, I have found nothing that beats keeping good notes. That way you will not reinvent the wheel some day down the road. Good notes will also rescue you from the fire of "something went wrong."

The rig is at 3.524. I double-tap the Split button to equalize the VFOs, then hold Split. The P3 is set to a span of 10, i.e. -5 appears to the left, +5 appears to the right. I set the P3 to tracking mode and move the green cursor to the left edge of the screen. What I'm looking for is that when I tune either the B VFO or the B marker up band, it reaches the far right edge of the screen when I get to 3.529, instead of reaching 3.529 when it gets just to the right of the screen center. In this set-up moving the B marker moves the A & B cursor and the marker and changes the center freq. displayed on the screen. That isn't desirable.

It must be somebody out there who is also using Microkeyer2 together with K3 and P3!! 73 /SM6BGG/Kurt Email: Kurt.Wiksten at tele2.se From matt at nq6n.com Fri Nov 20 10:45:30 2015 From: matt at nq6n.com (Matt Murphy) Date: Fri, 20 Nov 2015 09:45:30 -0600 Subject: [Elecraft] KPA 500 voltage drop on key down Message-ID: I just set up my KPA 500 and the HV on standby is 72.5 volts.

That should work fine for all except for loading firmware. To load K3 (or P3) firmware, do *not* connect through the Microkeyer2, connect directly to a PC serial port or USB to serial adapter. See the cautions on the MicroHam website about attempting to load firmware with the MicroHam gear in-line. 73, Don W3FPR On 11/20/2015 10:34 AM, Kurt Wiksten wrote: > I have just bought the P3-kit to work with my K3 S/N 23xx. > According to the P3 manual, the Male ?

The input from the K2 is present, although of course 5mW is pretty hard to measure accurately with my scope. There is also no signal at the input of the power amplifier module, but if I connect my scope probe to C48, at the output of the bandpass filter, and key the rig I have more or less correct output and a good 50MHz sinewave on the scope - as soon as I remove the probe the output disappears again. So the output module is fine and the fault would seem to be related to the U6 buffer or the bandpass filter. I am a bit mystified and need to sit down and work out what is really happening. Is there anywhere I should be looking? 73 Dave G3YMC http://davesergeant.com From cf at cfcorp.com Fri Nov 20 11:13:05 2015 From: cf at cfcorp.com (Cliff Frescura) Date: Fri, 20 Nov 2015 08:13:05 -0800 Subject: [Elecraft] KPA 500 voltage drop on key down In-Reply-To: References: Message-ID: <007901d123ae$56d6e2a0$0484a7e0$@com> Sounds like the amp is plugged into an outlet that is potentially overloaded or underrated.

You would need a very physically large front panel of your boat anchor form factor radio to support all that. In this modern age of radios, I think that menus and multi-function buttons and dials is the only way to go.

You want to use the largest power cabling possible when feeding the KPA500 (or any amplifier). The KPA500 goes from very little current to 10 amps or more very quickly. Resistance in the power wiring gets translated into heat loss and voltage drop, which you see as the lights dimming. This is one of the reasons many amp owners run their amps on 230V instead of 115V. It?s also the reason we ship a very beefy power cable with the KPA500. Unfortunately we can?t do anything about the wiring in your wall. You might want to have it checked or use a non-loaded outlet for the KPA500. I don?t believe that the manual actually states the lower limit for the 60V supply. For the record, the KPA500 will fault if that supply drops below 40 volts. This is really an overall power supply check - I don?t think I have ever seen the supply drop that low except in testing. The upper hard limit is 90 volts, which is where the transformer taps come in to play. You don?t want the supply to go above 90V when idle, so we have you set the tap according to your line voltage to make sure this is handled properly. If you do see a high voltage fault, then you should actually change the tap for a lower voltage to make sure we stay within limits. 73, Jack Brindle, W6FB Elecraft Engineering > On Nov 20, 2015, at 8:13 AM, Cliff Frescura wrote: > > Sounds like the amp is plugged into an outlet that is potentially overloaded > or underrated. > > Changing the tap won't solve the problem and may damage the amp. > > 73, > > Cliff K3LL > > -----Original Message----- > From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Matt > Murphy > Sent: Friday, November 20, 2015 7:46 AM > To: Elecraft Reflector > Subject: [Elecraft] KPA 500 voltage drop on key down > > I just set up my KPA 500 and the HV on standby is 72.5 volts.

Put an AC voltmeter on the AC line in a spare socket where the KPA500 is plugged in. Key it and watch the AC voltage. If it sags any more than 2 or 3 volts, you have a wiring problem of some sort somewhere. Amplifiers really should be on their own circuit (or a good stiff circuit if shared) back to the breaker box. *Especially* so if its 120V, even a KPA 500, which will draw a KW from the AC key down. Precipitous keydown drops in AC voltage at the socket means a fire hazard, and possibly some nasty problems in your AC wiring. No fooling around with this problem. Sometimes these kinds of things come from a problem in the power line neutral somewhere. That is really dangerous. 73 and Good Luck, Guy K2AV From ron at cobi.biz Fri Nov 20 13:10:58 2015 From: ron at cobi.biz (Ron D'Eau Claire) Date: Fri, 20 Nov 2015 10:10:58 -0800 Subject: [Elecraft] KPA 500 voltage drop on key down In-Reply-To: References: Message-ID: <000c01d123be$ced578b0$6c806a10$@biz> Matt, refer to your Owner's manual section, "Power Supply Transformer Tap" starting in page 8 to set the transformer tap. Your goal is for a voltage of 85V maximum "key up" as described in the text. You can't hurt the amp. If the voltage goes too high, the power supply will fault and shut down automatically. The KPA500 does heavily load a 115 VAC circuit. Most of the drop is likely between your breaker panel and the outlet and, of course, the further from the breaker panel you are the more drop you'll experience. One key point of loss is a bad wall outlet. The spring contacts in the outlet can grow weak over time and not make good contact. Be sure the wall plug fits snugly and does not come out easily. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Matt Murphy Sent: Friday, November 20, 2015 7:46 AM To: Elecraft Reflector Subject: [Elecraft] KPA 500 voltage drop on key down I just set up my KPA 500 and the HV on standby is 72.5 volts.

This means that the serial data will be scaled by the same amount. It will have affects on the auto-switching in the unit, as well as the alarm function. This means that if you set the alarm for 1000 watts and set the scaling so that 1000 watts is read as 500 watts, you won?t get an alarm. Conversely, if you scale so that 500 watts is indicated as 1000, you will see an alarm. I would not recommend modifying the connections into the pickup unit - you would have to modify all of the sensor connections, and it would have adverse affects on our ability to detect characteristics of the unit. Changing the scaling might be interesting for your use, though. If you try it, let us know how it works out for you. 73, - Jack Brindle, W6FB > On Nov 20, 2015, at 9:07 AM, Alan wrote: > > I just tested it.

The response to the turns count is actually a squaring function, so it would be difficult to remove turns and have the effect you want. The other problem is that the W2 firmware has a lot of data tables that depend on the values that are set in the sensor - changing the sensors means changing the tables. I believe that using the scaling factor that is already built in to the W2 would be the best way to achieve what Scott wants. It does have a down side, though. If someone else were to look at the scaled W2 and see the 10 LED light up, we would naturally think it was indicating 10 (or 1 or 100 or 1000) watts instead of whatever value Scott has scaled for. - Jack, W6FB > On Nov 20, 2015, at 10:08 AM, Michael Blake wrote: > > Alan, while I do not own a W2 it would seem that the pickup coils in the sensor could be reduced in turns by the correct amount to lower the coupling loss loss by 3 dB.

The probe can pick up RF and produce false output indications. The fact that you can induce output by probing C48 does normally indicate that U6 and U7 are capable of producing a signal. Check the LO signal. If that is good, then the problem may be in the 28 MHz bandpass or the mixer. I am puzzled by your reference to 5mW. The K2 with the K60XV has 1mW output - was that a typo? If you want to probe the 28 MHz IF in the XV50, you can re-plug the transverter for up to 5 watts input and you should be able to follow the signal path through the 28 MHz bandpass filter - all the way to the mixer input. If it works with the high level input, then try the low level input again - the 1mW input removes the attenuator and adds the gain of the Q6 stage. 73.

There would be no buttons or menus for all of those features or configuration items. The radio sets and optimizes itself. If there is QRM, the radio itself adjusts the bandwidth, notch, agc, etc. to get the clearest signal. If there is noise, the radio turns on the noise blanker and/or noise reduction and finds the best setting for the type of noise and the signal desired. It would all be automatic. The radio would set the mode, split frequency, etc all by itself. It would know what the signal is, and set itself up accordingly. If the DX station announced it was listening up 2, the radio would automatically set the TX up 2. So very few controls would actually be needed. Come to think of it, an operator wouldn't even be needed! Okay, so now I am thinking this silliness of mine is getting out of hand.

I rarely use the NB here so it usually surprises me when it happens. The K3 NB is made up of two parts: IF and DSP. For the IF NB, the spectrum is sampled ahead of the roofing filter and is quite broad. This allows the IF NB circuit to take out very short pulses. But when there is a strong signal (or many in the case of VK9WA) in that bandwidth it will cause what you are seeing. The strength of the effect somewhat depends on the IF NB level setting. The DSP NB, of course, is implemented in the DSP code which is after the roofing filter so it's not as susceptible unless the strong signal is inside the roofing filter passband. So if you can select a narrower roofing filter the effect will pretty much go away. Incidentally, this effect isn't unique to the K3.

Then I started listening on 20 ssb with my new 80/75/40 fan dipole. There was S79C working 5 up on 14.260 & abt a S5 on the meter. Unfortunately I haven't gotten to getting the Heil headset to work on the mic side, that's for tomorrow. Bottom line - after the initial intimidation I'm really motivated to get going on the air, tho I have worked S79 in the past :) Thanks again & 73 Jerry k1tgx From eric at elecraft.com Fri Nov 20 22:00:49 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Fri, 20 Nov 2015 19:00:49 -0800 Subject: [Elecraft] K3 NB problem In-Reply-To: References: Message-ID: <564FDE61.7030300@elecraft.com> Hi Larry, For the IF NB I usually use a level of 3, or 4 max, with a narrow typically for the width. This generally works quite well for me with minimal intermod. More aggressive thresholds and wider widths significantly increase the likelihood of nearby strong signal intermod with IF based NBs. As another poster mentioned, the DSP NB can be cascaded after the IF NB, or just on its own. So trying different combinations of these may also help in your situation.

Seems like the NB settings on the K3 are causing IMD and phase noise from the pileup up the Band a bit to sound like rain static and jump to a level of S5-6 on the K3 meter! Never ran into that before with a K3... Then again, except for this new electric fence pulse, I never needed to use the NB for anything at this previously dead quiet location.

Having looked at it again it does actually look as if the output from the K2 transverter socket is missing or very low. I got a bit confused about levels (as well as making typos) and I should most definitely be able to see the 1mW on my scope (632mV p-p). I did have to tighten up the locknuts on the phono sockets at the K2, maybe there is an open circuit or short circuit there as well. Will take the K2 apart again later and check, but the XV50 is probably OK. 73 Dave G3YMC On 20 Nov 2015 at 14:28, Don Wilhelm wrote: > Dave, > > Be cautious with conclusions when probing with a 'scope probe in the 50 > MHz section of the XV50.

The available choices now are NAR/MED/WID with 7 degrees of level. Electric fences are wide pulse. I have observed that width vary based on the manufacturer and the quality of the installation; read - all terrible! This is almost exclusively due to inadequate (_non existent_) grounds, bare wire nailed to tree trunks, wire connections that are not really connections at all and the inevitable brush/branch/grass growth along the wire paths. All the JA manufacturers since the 1970s built 40lb primary station radios with noise blankers set to eliminate automobile ignition noise! ICOM with their IC-781 in the late 1980s added a width control along with the level control. Besides my K2 & K3 I have an ICOM 7600. The latest iteration of it's menu system allows adjustable NB level 0-100%, depth 1-10 (still not sure what it does; I leave it at 4) and width adjustable 0-100. With the NB Width control set half way at 50, I can eliminate the pulsing with a Level setting of 50%. If I try that on 160/80 CW chasing DX the pileup will blow the IF away. Increasing the Width to 75 and reducing the Level to 20% the fence pulsing is close to non existent but the pile up is not overloading the IF.

The pin of the BNC plug at the XV50 end had pushed back so not making. Together with the BNC/phone adaptor at the K2 end which is not the best arrangement. I obviously need to make up a couple of proper phono-BNC cables. I assume the BNC sockets on the XV50 are 50 ohm variants. I know the pin diameters of 50 and 75 ohm are supposed to be compatible but maybe that on the off the shelf BNC lead I used, presumably 75 ohm, has thicker pins which caused the issue. 73 Dave G3YMC On 21 Nov 2015 at 10:45, Dave Sergeant wrote: > Thanks Don.

It seems we have arrived. OTOH, there is the challenge of building the robot and making it work that is sure to appeal to many, while some of us prefer to ride a horse instead of a 4-wheeler, split fire wood with an axe instead of a hydraulic ram and on the air we quite literally "pound brass". It's amazing how broad the range of interests in Ham radio have become. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bill W4ZV Sent: Saturday, November 21, 2015 2:05 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] didn't make myself very clear :( "So very few controls would actually be needed.

In the menu settings MIC BTN change from UP.dn to off, then turn on VOX, just to the left of VFO A tuning knob. The other solution which is a little more elegant is to tell your JT65 software to use CAT control as the PTT method. I use WSJT-X on Linux, the setting is in File->Settings, then click on the radio tab. Under RIG select Elecraft K3/KX3, then whatever serial port you are using, then your baud rate-probably gong to be 4800, unless you are using a KXPA100 then the bauud rate will be 38400 most likely. On the right hand side of the window under PTT method select CAT.

I've surely done that myself, once with the equipment out and ready to ship before logic gained the upper hand and I started checking cords and connectors, finally detecting a male BNC on a cord with a retracted center pin. Sound familiar? :>) So many of us have had experiences like this. Cord goes bad and to start off we spend time trying to figure what's the matter with the box, the K3, the transverter, etc. One local ham went nearly nuts thinking his box had been supplied with non-standard type F female chassis connectors until a friend discovered that the male F connector in question had not been threaded in the manufacturing process ! That story was source of a lot of local ham laughs. Carefully checking the cords and connectors *first* seems to be counter-intuitive. While logic says that connectors and wire in the cords take all the mechanical abuse, our gut lurch is elsewhere. Maybe it's because making cords is such a royal pain in the *ss and our subconscious is rebelling against making another jumper. I share your pain.

But obviously these cheaper ready made up cables use cheap plugs so may well have fat pins. As an interim measure I have taken a couple more of the cheap BNC/BNC leads and chopped one of the plugs off and fitted a phono plug, which at least gets round the problems of adaptors - still 75 ohms of course. A quick search shows that all made up BNC-phono leads are 75 ohms so to go to 50 ohm leads you really do need to make it up yourself - and I don't seem to have any BNC plugs in the spares box at the moment. This has got it up and running again, but I have revealed another issue - the earthing of the phono sockets in the K60XV at the K2 end is not ideal. Only the output phono has a grounding lug, the input phono relies on earthing via the aluminium panel. Although there are crinkle washers both sides of the socket the socket tends to wear loose every time you put the plug in. The receive noise on the XV50 shows this, as you wriggle the cable at that end the noise goes up and down. It really needs a direct earth to the ground on the K60XV panel. I guess now having got it going not much else will happen until the sporadic E season starts next May... 73 Dave G3YMC On 21 Nov 2015 at 19:44, Danny Higgins wrote: > I remember buying some cheap BNC patch leads at a rally which worked > fine.

Unless someone used substitutes, they have a hex nut on each side of the panel and an internal tooth lockwasher on each side of the panel too. Use wrenches (spanners for you) or pliers and tighten them securely. The internal tooth lockwashers need to 'bite' securely into the aluminum. 73, Don W3FPR On 11/21/2015 3:03 PM, Dave Sergeant wrote: > This has got it up and running again, but I have revealed another issue > - the earthing of the phono sockets in the K60XV at the K2 end is not > ideal.

What if on landing approach I lower the landing gear and one does not extend and lock? What if I pull back the throttles to cruise setting after take-off and #2 quits. What if on a cold winter day I take off, have the airplane off of the runway and look at the panel only to discover the airspeed is zero!

There is a seemingly little-known failure that frequently occurs to Bird meter movements ... or more correctly ... to the connector at the sensor casting end of the length of coax used to connect the (30 ua) meter to the sensor. Often a sharp "whack" on the housing will cause the meter to resume working, often for long periods of time. The connector's internal connection is made by inserting the (solid) center conductor of the coax between turns of the coils of a tiny spring that's part of the center pin assembly of the casting end's cable connector. There's such a tiny amount of current flowing through the coax center conductor and the spring "connection" that it seems to corrode easily, and most assume the meter movement has failed. The resulting tiny disturbance to the wire/spring junction is why the "slap" on the housing often brings the meter back to life. Many of the expensive proprietary meters have been needlessly replaced because of this. 73 - K0PP From w5sum at comcast.net Sat Nov 21 18:24:00 2015 From: w5sum at comcast.net (w5sum at comcast.net) Date: Sat, 21 Nov 2015 17:24:00 -0600 Subject: [Elecraft] Stereo Speaker for K3 Message-ID: <84D4D90CEE6446BCB001253AB9693734@MININTMC1HLDC> I?m interested in getting a nice stereo speaker for my K3 so I can listen to both of my rx?s at the same time without having to wear cans.

Those small speakers were popular some time ago. I picked up a pair of Radio Shack Optimus speakers in a second hand store for $5 and they work great with my K3 - those speakers are 5 inch cubes. They are not powered - just speakers, so no worry about RF getting into the amplifier. Alternately, build your own small speaker enclosure and mount a good high fidelity speaker inside (look at the audiophile sites). Get a full range speaker - the speaker should not restrict the audio frequency response, the K3 has the RX EQ which will allow you to tailor the audio response that you want to hear. With my KX3, I needed amplified speakers, and after many trials with PC speakers which howled during transmit, I 'bit the bullet' and ordered a pair of West Mountain Radio COMspkrs - shielded and nary a sound of RF feedback from them even with the KXPA100. They are a bit larger than I would like, but they do work fine. They will work great with the K3. 73, Don W3FPR On 11/21/2015 6:24 PM, w5sum at comcast.net wrote: > I?m interested in getting a nice stereo speaker for my K3 so I can listen to both of my rx?s at the same time without having to wear cans.

"Technician (or Engineer), know your test equipment and especially know its limitations". That means always be prepared to verify your measurement equipment readings by some other means rather than trusting the indication of any one instrument. In other words, if your test gear is telling you something that looks "funny", verify the test equipment as a first order of business - use an alternate measurement method to do a 'sanity check' and remember that test equipment can fail just as well as the equipment under test. Trust no piece of test equipment that cannot be verified for correct operation. As an example, I have a wattmeter that is supposedly good for HF as well as VHF/UHF. The VHF part starts above 30 MHz. When I had problems getting XV50 transverters to develop 20 watts as indicated on that meter, I used an alternate power meter and discovered that wattmeter took 36 watts to indicate 20 watts on its meter on 50 MHz. On 144, 220, and 432 MHz it was accurate. So that condition is now plainly marked with a sticker on that meter. Verify before believing the meter in use. I know that such verification is not always within easy reach for the average ham, but usually there are locals with test gear that can be borrowed to give you a validation of whatever test equipment you are using (test 3 and let the most common vote be the deciding factor). You do not have to pay the cost of a calibration lab to do that kind of verification of your test gear, but do be suspicious if you have not validated your test equipment in some manner. 73, Don W3FPR On 11/21/2015 6:23 PM, Ken G Kopp wrote: > An earlier posting brings this to mind .... > > There is a seemingly little-known failure that frequently occurs to Bird > meter movements ... or more correctly ... to the connector at the sensor > casting end of the length of coax used to connect the (30 ua) meter to the > sensor. > > Often a sharp "whack" on the housing will cause the meter to resume > working, often for long periods of time.

I received seven boards and some parts from Byron. The boards are separated and drilled. I have been talking to the Internal Mic Adapter folks about getting some of the IMA boards. Today I sent a check for 20 IMA boards. I need to order enough parts to finish out the seven MAB board sets on hand. Before I order parts, I would like to see if there is enough interest to order another 9 MAB boards. So now is the time to let me know if you really want a MAB board. They will be furnished assembled, with the Mic adapter board installed. Pricing depends on how many sets of parts I order. The larger volume of parts, the lower I can get the price for everyone. Your cost will be just above my parts cost and shipping. You can find more information about the MAB project at the link below. If you are interested please let me know as soon as possible. I will be ordering parts next week.

For instance trying to measure an HF signal with a 'scope. The 'scope may b rated for 200 MHz, but if you try to us a "hunk of coax" for a probe, the frequency rating may diminish to 2 MHz (OK, that is just an example). You need to consider the whole measurement system. A scope's frequency rating must also be coupled with the frequency rating of the probe. The use of 10X probes is necessary to keep capacitance loading of the circuit under test to a minimum. And those probes have a frequency rating too. Take the entire setup of the test equipment into consideration when doing measurements. Make certain that every part of the test equipment being used is suitable for the frequency involved. A simple coax probe may be OK for AF frequencies, but it is not adequate when the frequency is increased. A 'scope can show proper RF voltage amplitude, but the frequency rating of the probe and the 'scope should be taken into consideration. For instance, a 35 MHz scope will only show a signal that is 3 dB down at 35 MHz. I would suggest that valid RF voltage measurements be made at 1/10 of the 'scope's frequency rating (and that goes for the probe too). Again I state, trust no measurement equipment until its accuracy has been verified. 73, Don W3FPR On 11/21/2015 10:09 PM, hsherriff wrote: > I'm the supervisor of a metrology lab and that is one of the first > things I ensure a new technician understands.

It is the most overrated power meter, especially in the amateur community. The calibration is only possibly five percent at a single frequency, usually the center frequency of the slug. Away from that frequency it rapidly goes way off , I have seen as much as 30% in the range of the slug. It?s a very rugged meter, used to confirm a rough level of RF. It is better at confirming a SWR, as the frequency error is the same in forward as in reverse. I have seen many new slugs that could not be calibrated to >10% over a 10Mhz range. Accurate power meters have frequency calibration factors for each power head sensor., in modern ones it is sometimes in a PROM in the sensor head. I have told this story many, many times in the ham community. Bird marketing may be the reason for the ridiculous reverence for them in the ham community. You can drop one from the tower and it will probably work as poorly as it ever did, one of their only strengths .

Some of this was the "fault" (i.e. normal operation) of the noise blanker; some of it was due to the absolutely abysmal quality of too many of the signals. Regrettably, there were probably some K3s contributing to the mess if some recent QSOs I've had with other owners are any indication. Although I often get unsolicited kudos for my audio, I recently had a 17-meter ragchew with a W6 transplant in GA whose K3 sounded simply awful and looked it on the spectrum scope. Regarding the K3 NB, frankly, I wonder why, with a radio with so many "smarts" built in, we have to adjust I-F NB parameters at all. Setting the threshold automatically, under most conditions, should be automatic and extending the blanking pulse width to match the noise impulse duration should be trivial. See: http://k6mhe.com/n7ws/Noise_Blanker.pdf for some ancient work. (I actually wrote this paper as a final exam for a technical writing course I took. We were told to write something suitable for publication, including letters of submission and a release from the company I worked for. I said to myself, "Self, you've done all of the work, why not just for the heck of it submit it to a ham radio publication? Since the company only gave "published papers awards" for peer-reviewed publications, I figured I really didn't require their approval so I sent it to Ham Radio Magazine and they paid me instead. A couple of years later a guy said to me, "I see your circuit was published in Bill Orr's Radio Handbook." First I knew about it. One would think that a guy who stole your work would at least give you a free book; but no.)

Would like to point out that some commercial scopes these days come with probes that are inadequate for the bandwidth of the scope they are connected to. The scopes might be rated foe 100 MHz but with the supplied probes the system is lucky to make 50 MHz. Tektronix was an exception. Their bandwidth specs were met with factory probes. Unfortunately the only way to know is to test the entire systems response with a calibrated generator. One bargain sampling scope I bought was not such a bargain after buying several sets of probes to find ones meeting bandwidth specs. Even then the best match probe had to have its ground lead shortened a bit to flatten the response. Developing a trust in ones test equipment takes effort and time. 73 de Brian K3KO Sent from my iPad > On Nov 21, 2015, at 10:58 PM, Don Wilhelm wrote: > > Harlan, > > That is correct - improper test leads are often a 'culprit'. > For instance trying to measure an HF signal with a 'scope. The 'scope may b rated for 200 MHz, but if you try to us a "hunk of coax" for a probe, the frequency rating may diminish to 2 MHz (OK, that is just an example). You need to consider the whole measurement system. A scope's frequency rating must also be coupled with the frequency rating of the probe. The use of 10X probes is necessary to keep capacitance loading of the circuit under test to a minimum. And those probes have a frequency rating too.

For instance, a 35 MHz scope will only show a signal that is 3 dB down at 35 MHz.

In the commercial RF generator business we used Bird's. But every 6 months we calibrated the unit with a calorimeter for the specific frequency of our generators. We would make a new meter face and also tape the slug to the particular meter so it couldn't be changed. We bought a lot of slugs. It was not unusual for a brand new slug out of the box to be off >30%. Birds are good as a loose measurement device. By the way, one year at Dayton I picked up a couple used Drake W-4 wattmeters. They were surprisingly accurate on 20M. Today there are better choices in wattmeters for the shack. 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of lmarion Sent: Saturday, November 21, 2015 11:35 PM To: Ron D'Eau Claire ; elecraft at mailman.qth.net Subject: Re: [Elecraft] OT: Bird Wattmeter "meter failures" The Bird wattmeter is a coarse and loose measurement device.

Actually, I don't condone physical punishment of children. A word or a look can do much more...my Dad was a master at that and I guess I picked up some from him. But back to electronics: I recently had a transverter customer call that it wasn't showing anything on his Bird meter. The internal LED bar meter was showing RF output which is driven by a simple diode. So there was RF at the output of the unit but none at the meter. First thing I suggested was trying a different coax jumper, then I suggested a different element. Interestingly he said received a beacon 60 miles away just fine - hmm. That told me the internal coax and LO were working. Had him check some other connections. Finally, I told him to connect the antenna and try making contact with a nearby ham. He called me later to say that he made the contact and got S7 report. He then confessed that the Bird was unused for a couple years and stored in his garage. I asked if he had a 2m FM radio that he could use to test the meter and he said, yes. Haven't heard back but I'm guessing he discovered the meter was not working. He had another Bird meter to try, but it was also stored in the garage. He lives in a humid climate on the Gulf of Mexico. As Don put it know your test equipment and don't jump to conclusion the radio has failed. I look at wires first. Oh and make sure the PS is turned on! ;-) I drove two hours to a customer's house to determine why his satellite TV quit...wife knocked the ac cord out of the wall socket with vacuum behind the book shelf entertainment center.

We've all asked questions here which were repeats of questions asked, answered, and the responses archived. I find the archives for this group to be sometimes a bit overwhelming and cumbersome to work with. It is possible to miss something that is in there. Most of the members of this group will simply either ignore the fact the question has been asked and answered, or answer the question, and then point out that you can also search the archive for previous questions/responses. And you will NEVER get a mean-spirited or nasty response from any of the Elecraft employees who monitor this list. I know I sound like a Kool-Aid drinker (I prefer to think I go head-first into the punchbowl, myself :-) ), but Eric and Wayne have gone out of their way to hire staff who are not only very knowledgeable in their particular areas, but who strive to help us poor users make sure we have the best experience possible, regardless of which piece of Elecraft gear we own. Keep posting those questions, and they'll keep getting answered properly. 73 de, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik.ian at gmail.com 10-10 #74624, North Georgia Chapter #2038 PODXS 070 #1962 K3# 281, P3 #688, KAT500 #860, KPA500 #1468 -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of w5sum at comcast.net Sent: Sunday, November 22, 2015 6:12 AM To: elecraft at mailman.qth.net; Bill Subject: Re: [Elecraft] Stereo Speaker for K3 Thanks for the positive responses y'all, I'll pick up some speakers soon. as for the unpositive responses off the list, dang..

How long does it take for the power to begin increasing and does it reach a limit? or does it continuously increase? The K3 and K3S will normally reduce power after a band change or a change in the power knob, then it should rapidly increase power to the power level that you have set. It is done that way to eliminate the possibility of an overshoot. Is this initial adjustment of the power what you are observing? Or does the power climb to above the requested power level? I don't know anything specific about the K3S with the USB audio interface that should cause that behavior. If the power increases above the requested level, there is a problem with the power control circuits in your K3S and you need to contact K3support. Take the KPA500 out of the picture and connect the K3S directly to a dummy load through an in-line wattmeter to see what is really going on. 73, Don W3FPR On 11/22/2015 10:05 AM, Howard Sherer wrote: > When I use the Data A or AFSK A modes, I set my line in to just fill the > lower 4-5 bars of the ALC scale, and then adjust the pwr out for the > desired level. what occurs when I xmit is an increase in RF output as it > rapidly drifts up.

Sorry to hear that you have encountered some "nasty spoilsports". I may encourage newcomers to review the list archives to provide additional information, but I will never admonish a newcomer for asking a question. This is an email list, and not a FAQ listing. Back to the speakers question, Elecraft has recently released the SP3 which works great with the K3 and K3S, but if you have the KX3 in your home station, you really need amplified speakers. As I stated before, shielded speakers are a 'must' because most amplified computer speakers will 'howl' in the presence of RF (it depends on the band). At the workbench, I have that situation with my standard issue computer speakers even at 10 watts working into a dummy load. Since I know what to expect (and I am just testing at the workbench, not operating, I ignore it, but that would not be tolerated for the hamshack). If you need good shielded and amplified speakers, I can vouch for the West Mountain Radio COMspkr. It works FB with my KX3 with KXPA100. With the K3, non-amplified speakers work fine, and I will continue to use my bargain basement RS Optimus speakers. If you have the K3 or K3S and are looking for speakers, the Elecraft SP3 is a great choice (it is not an amplified speaker) and matches the K3, K3S for those who like matching components. 73, Don W3FPR On 11/22/2015 6:12 AM, w5sum at comcast.net wrote: > > Thanks for the positive responses y'all, I'll pick up some speakers soon. > > as for the unpositive responses off the list, dang..

If you have a calibrated 1000 watt slug and meter it will read within 100 watts of the real power. What many people miss is that the possible 100 watt error is constant over the range of the meter, so measuring 500 watts the meter will indicate something between 400 and 600 watts and at 100 watts the reading can be off by a full 100%! That's why they make a variety of slugs for various power readings. For anywhere near +/-5% accuracy you need a slug that produces a reading near full scale at the desired power output. Preparing radios for an FCC inspection I used a Bird 43 because the FCC field engineer used a Bird 43. All I cared about was whether when he hooked up his meter it read within specifications for the radio. A regular thread on the reflector is about how much accuracy is important. It's obviously a matter of opinion. If I voice any opinion it will trigger endless responses with other opinions. So I'll stop right here. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of lmarion Sent: Saturday, November 21, 2015 8:35 PM To: Ron D'Eau Claire; elecraft at mailman.qth.net Subject: Re: [Elecraft] OT: Bird Wattmeter "meter failures" The Bird wattmeter is a coarse and loose measurement device. It is the most overrated power meter, especially in the amateur community. The calibration is only possibly five percent at a single frequency, usually the center frequency of the slug. Away from that frequency it rapidly goes way off , I have seen as much as 30% in the range of the slug. It?s a very rugged meter, used to confirm a rough level of RF. It is better at confirming a SWR, as the frequency error is the same in forward as in reverse. I have seen many new slugs that could not be calibrated to >10% over a 10Mhz range. Accurate power meters have frequency calibration factors for each power head sensor., in modern ones it is sometimes in a PROM in the sensor head. I have told this story many, many times in the ham community. Bird marketing may be the reason for the ridiculous reverence for them in the ham community. You can drop one from the tower and it will probably work as poorly as it ever did, one of their only strengths . Leroy AB7CE , retired NIST calibrations standards technician.

Sorry to hear that you have encountered some "nasty spoilsports". I may encourage newcomers to review the list archives to provide additional information, but I will never admonish a newcomer for asking a question. This is an email list, and not a FAQ listing. Back to the speakers question, Elecraft has recently released the SP3 which works great with the K3 and K3S, but if you have the KX3 in your home station, you really need amplified speakers. As I stated before, shielded speakers are a 'must' because most amplified computer speakers will 'howl' in the presence of RF (it depends on the band). At the workbench, I have that situation with my standard issue computer speakers even at 10 watts working into a dummy load. Since I know what to expect (and I am just testing at the workbench, not operating, I ignore it, but that would not be tolerated for the hamshack). If you need good shielded and amplified speakers, I can vouch for the West Mountain Radio COMspkr. It works FB with my KX3 with KXPA100. With the K3, non-amplified speakers work fine, and I will continue to use my bargain basement RS Optimus speakers. If you have the K3 or K3S and are looking for speakers, the Elecraft SP3 is a great choice (it is not an amplified speaker) and matches the K3, K3S for those who like matching components. 73, Don W3FPR From frantz at pwpconsult.com Sun Nov 22 13:06:21 2015 From: frantz at pwpconsult.com (Bill Frantz) Date: Sun, 22 Nov 2015 10:06:21 -0800 Subject: [Elecraft] Can I pre set Data A mode in a memory In-Reply-To: Message-ID: I have the 4 per-band memories on my K3 set up to set modes and go to appropriate parts of the band.

About a year ago I picked up a set of Pye PCB3BK 3.5" cube speakers ... a perfect size to set on either side of the "K-Line" ... for about $25 on Amazon.com. Since then, I've picked up several other pairs for my second K3 and other rigs. I like the PCB3BK because its 90 Hz - 18 KHz response is far more appropriate for "communications". They do not rumble and turn muddy with low frequency noise like the larger bookshelf speakers and/or amplified speaker systems while the high frequency response is more than enough to prevent distortion on the high end. They are efficient enough that the K3's audio amplifier is capable of creating more than 90 dBa sound levels without running into apparent distortion. 73, ...

The order page separately lists the SP3 external speaker and the Second SP3 external speaker but listed with the same price of $179.95. The first entry on the order page says ?(main/sub audio)? and the second SP3 entry says ?(for stereo FX, separate main/sub audio)?. What is not clear to me is whether these two speakers are IDENTICAL or DIFFERENT in some way. The photos linked with the Order page only show the face of one speaker, not the back. I think I remember seeing a more detailed data sheet on the SP3 that might have shown the back connections and that might have given hints whether these two speakers are the same are not.

You need to be sure you shut that off when you wire it direct. I did a demo many years ago, when PSK31 was the new guy on the block, where I had a laptop on one end of the meeting room for our ham club and the receive audio source on the other end. It copied perfectly, even with the room acoustics.

Computer Line Out to K3 Line In, and K3 Line Out to the computer Line In (or mic in). If your computer has only Mic In, look in the soundcard properties window to see if you can set that input for line level. Tell Fldigi to use that internal soundcard. The K3 and K3S have galvanic isolation built in, so there is no real need for an isolated interface box. Turn off Windows Sounds so you do not play those over the air. Use VOX on the K3. With data modes, there is no concern about ambient room noise triggering the VOX. After experimenting with that setup, decide whether you want to use your existing SignaLink with the K3 or whether you want to buy another external USB soundcard - compare the cost of the USB soundcard vs. the K3 cables for the SignaLink. Many adequate soundcards are available at low prices. Look at Amazon and Ebay for example, most any soundcard will do for data modes. If you have aspirations about using the K3 and LP-Pan for panadapter use (in lieu of the P3) then get a USB soundcard that will do that job - 24 bits and a 192kHz rating with a low noise figure (see the soundcards listed at www.telepostinc.com) instead of the low price soundcard. By switching the audio cables, you can use that soundcard for both data modes and the panadapter application. 73, Don W3FPR On 11/22/2015 2:33 PM, Steve via Elecraft wrote: > I think I may just be overcome by an embarrassment of riches.

In the K3, there is an RS-232 port rather than a USB connection - no soundcard in the K3 - at least until the KIO3B option is available, and then more confusion will be present and will result in asking if the owner has the KIO3B or the K3 original KIO3. Your answer is correct for the K3S, but not for the K3.

Why would one want to use an amplified speaker on a K3 since the radio already has an amplifier? Doing so would seem to invite distortion and RF pickup. The K3's audio output is supposed to have a 4 ohm load and computer speakers are probably closer to 1000 ohms. It's almost like having no load at all. I don't think that's good for the K3's output chip. I have the West Mtn. speakers here and they sound rather poor compared to almost any comparable computer speaker.

An audio amplifier will operate into a 4 ohm or a 1000 ohm load just fine. With the 4 ohm load, power is required, but for a 1000 ohm load, not much power is necessary. But more direct to your question, the K3 or K3S does *not* need amplified speakers, but for the KX3 you will likely want amplified speakers for adequate volume in the home hamshack application - the audio amplifier in the KX3 is designed for low receive current draw and that means it does not have powerful audio, but is entirely sufficient for headphones or the efficient internal speaker. There is no harm in using amplified speakers on the K3 (K3S) but it has enough audio power to use non-amplified speakers. Yes, ordinary computer speakers are subject to RF pickup resulting in 'howls' and other noises during transmission, thus my recommendation to use shielded speakers (if they are amplified) in the hamshack. The COMspkr is a communications quality speaker, and is great for normal ham use. If you want full range audio for HiFi SWLing, use something else. 73, Don W3FPR On 11/22/2015 4:15 PM, Steve Ellington wrote: > Am I missing something?

This also applies to almost all watt meters as well, and that is the power calibration is relative to a 50 ohm load only. Any other load Z will introduce errors in the meter accuracy and indication. At the same time, the ratio measurement for forward power and reflected power will always be correct in that each value will be measured with the same degree of error. Thus using this information, one can accurately calculate the SWR using the forward power indicated and the reflected power indicated. Where as, absolute values will not necessarily be accurate under these conditions. 73 Bob, K4TAX On 11/22/2015 11:38 AM, Ron D'Eau Claire wrote: > Bird instruments specs a Bird 43 at plus or minus 5% of full scale. If you have a calibrated 1000 watt slug and meter it will read within 100 watts of the real power. What many people miss is that the possible 100 watt error is constant over the range of the meter, so measuring 500 watts the meter will indicate something between 400 and 600 watts and at 100 watts the reading can be off by a full 100%!

Since the K2 did not tune above 30 MHz (and did not do FM), there was not much interest in having the XV144 output to be above 146MHz. Enter the K3 with its FM capability and tuning above 30MHz and the picture becomes "cloudy". I do not know the range of the 28MHz nor the 144MHz bandpass filters in the XV144, so I cannot directly answer your question. Certainly the XV144 could be tuned to provide whatever coverage of the 2 meter band that you choose, but I do not know if the bandpass is sufficiently wide to cover the entire band with full power output or full RX sensitivity. 73, Don W3FPR On 11/22/2015 4:55 PM, Peter Pauly wrote: > The datasheet for Elecraft's external transverter says that the IF > frequency is 28-30 Mhz.

The manual covers those items quite nicely, but you have to know what microphone and whether it needs bias or not. Those are the subtle things that cannot be covered in the manual because there are so many variations. 73, Don W3FPR On 11/22/2015 5:05 PM, David Glasser wrote: > Hi > I am a real newbie searching for someone in the Orlando area (I live just south of Disney!) who owns a K3S and who has the patience to chat through the things I need to consider in setting up a shack for a soon to be acquired K3S!! > All help small or big would be greatly appreciated. > I have overcome my first hurdle by convincing our HOA to grant permission to me for the erection of a 30ft vertical antenna! > I can be contacted at: > From k6uj at pacbell.net Sun Nov 22 17:46:02 2015 From: k6uj at pacbell.net (Robert Harmon) Date: Sun, 22 Nov 2015 14:46:02 -0800 Subject: [Elecraft] OT: Bird Wattmeter "meter failures" In-Reply-To: <56523DFB.9020405@blomand.net> References: <56510BF9.2050204@pacbell.net> <5651186E.20501@blomand.net> <001501d124d8$0ec51d30$2c4f5790$@biz> <51BD47B71B744B3EBE8BCF98E5A7630E@LeroyPC> <006101d1254c$9f4f1f80$dded5e80$@biz> <56523DFB.9020405@blomand.net> Message-ID: <565245AA.1010700@pacbell.net> Thanks for all the info on diagnosing the intermittent problem with my Bird 43 guys !

The problem is RFI in the audio input (microphone input) when I use my vertical antenna on 40 meters.

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.

Do be prepared to check the test gear prior to taking measurements. While that is not practical in most cases, do be suspicious of your measurements until you have taken steps sufficient to validate your test setup. I do not know how to tell you how to validate your test setup in detail, because that will vary depending on the equipment used, but what I am saying is that you should not trust the indication of any measurement device at face value. Verify that the measurement device is giving proper indications as the fist order of business - or at least second order when measurements begin to "look funny". 73, Don W3FPR On 11/22/2015 5:46 PM, Robert Harmon wrote: > Thanks for all the info on diagnosing the intermittent problem with my > Bird 43 guys ! > I discovered their was a poor connection where the RG58 from the meter > movement > connects to the element.

Refer to the writings of Jim Brown K9YC for effective baluns (he prefers common mode chokes because balun is not a specific thing - some good, some bad). Look at chapters 6 and beyond of http://audiosystemsgroup.com/RFI-Ham.pdf to eliminate the theory and get right to the subject of constructing effective common mode chokes for HF. Keeping RF out of the shack is your first measure of defense. Cure the antenna field problems and if there are still problems, then try ferrites on the station equipment lines. 73, Don W3FPR On 11/22/2015 6:02 PM, Jan Ditzian wrote: > I have a problem that appears to be changing, but I could use some > help.

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.

Elevated verticals will treat the [outside of the] feedline as a random length radial. The current on the feedline will be proportional to how close the feedline length is to a quarter (or half) wavelength depending on whether the chassis of the transceiver/tuner/amplifier is floating/grounded. It is *imperative* that there be a high quality common mode choke on the feedline at the feed point of the antenna. "Ugly balun" or other random solenoid wound chokes are not reliable - see the work by K9YC, GM3SEK, etc. and select a choke that shows at least 5 K (preferably 10K) choking impedance on 80 and 40 meters to disconnect the outside of the coax shield from the antenna. > The microphone for the K3 is an Audio-Technica that works well > everywhere else. Assuming the Audio-Technica has an XLR connector, make *sure* the shield (pin 1) is *not* connected to the mic return (pin 7, pin 8) and depending on the age of your K3 make sure there is no RF choke between pin 7 or pin 8 and the circuit board ground. 73, ...

Basically, a "combiner" is a transformerish arrangement which isolates the ports from each other to keep them from interfering while maintaining the correct impedance. They can be pretty simple and inexpensive, with basic versions requiring just a couple of small ferrite cores (of the correct mix for the frequency range involved) with tapped or bifiliar windings and a terminating resistor or so. The following articles explain things far better than I can: AN10-006 Understanding Power Splitters - Mini Circuits www.minicircuits.com/app/AN10-006.pdf ?

Perhaps where the feed line enters the house. A common mode choke can be also known as "The Ugly Balun" http://www.hamuniverse.com/balun.html or can be a series of ferrite beads on a section of coax.

With nothing but power and a dummy load connected to the K3, while in TUNE on 10 meters, PWR adjusted to 15 watts, the K3 momentarily stops transmitting every 15 seconds. When I push the TUNE button it starts transmitting. After 15 seconds the K3 momentarily stops transmitting for about a millisecond, again at 30 seconds, again at 45 seconds, and again at 60 seconds and so on. The same result in both CW and DATA modes. If I reduce the power to under 12 watts, the K3 transmits continually. Has anyone experienced or duplicated this characteristic with their K3?

I'm using a STEPPir vertical for 40 through 10. I tried several baluns with no satisfying success. I then decided to build a SPGS (single point grounding system) on the outer wall next to my shack in the back yard. My SPGS is enclosed by DX Engineering's "Grounding and Utility Encloser," (DXE-UP-2P) and I installed in that three ALPHA-DELTA lightning arrest (surge protectors) (for three different antennas, one being a Beverage), and a CONTROL LINE PROTECTOR, (DXE-IS-RCT), that protects my Steppir vertical antenna control system. In addition to that I ran #6 copper to the house utility box ground (from the antenna ground) AND (perhaps most important) ran three ground rods spread out (at twice the length of the 8' rods) and connected all of that to the vertical grounding plate (of the SPGS box) The important thing is that I did not use #6 wire from the vertical to the SGPS box; instead, I used 2 inch wide copper strip that is bonded to the rods with copper plates and connections at each end of the run. The 2 inch copper strip is then attached to the SPGS 14 x 14 plate (with another ground rod) just outside the house. THE THEORY IS THAT THE WIDE STRAP PROVIDES FOR A VERY LOW RF IMPEDANCE AT THE FREQUENCY OF OPERATION. This substantially shunts off any interference returning on the outside braid of the coax from the vertical. In addition on the inside (at station) I ran a strip of the 2 inch copper along the back of the station table and then smaller braided strap from the copper strip to each major piece of equipment on the station (a reverse V from the SPGS if you will) : DELL OPTIPLEX COMPUTER (station computer), two 19 in flat screens, my fully loaded Elecraft K3 with P3 WinkeyerUSB, and Astron switching supply. The result was immediately apparent: the spikes I had been receiving that were spaced up and down the 40 through 20 bands as noted on the P3 panadapter where now completely gone. An added surprise was that the noise floor even went down a bit (and I live two blocks from a shopping mall!). Prior to this large station upgrade - inside and outside the house - I would even see interference on the 19 inch screens - that is now gone too. If you like I can send you more detail on what I did, including pictures. I've only been testing it for a week so may find some glitches....but so far very happy. 73 and good luck.

There is pin #1, pin #2 and pin #3 plus a ground terminal. The cable between the mike and radio should be 3 conductor shielded. Thus - Red, Black, White and shield.

That way I can cover the whole 3 MHz of the "new" 1?M band from 222 to 225 MHz. Admittedly, I have not yet tried it with my new K3s, but with the original K3, Elecraft sent me a program to allow transverter ( low level ) output down into the chicken band. The program may allow output down to 26 MHz which may also solve the problem of the 4 MHz wide 2M band. I don't think the program would allow any significant power output at 27 MHz, but it was perfect for my needs. I sold my K3, so I need to ask them again for that program so I can get my new K3s working on the 220 ( I still call it that) band. As an aside, I don't think anything ever came of that total guvmint fiasco where 220 to 222 was taken out of HAM service but we were give some space below 220 to use.

I have read EVERYTHING on the internet about this subject, and have now been experimenting with the PLL frequency compensation board, changing the RA value, with mixed results. Here's my question...I see that the compensation unit varies the voltage applied to the varistors with changing temperature. I am wondering if it would be feasible to replace that unit with one of the huff puff type stabilizers like the x-lock or K4DPK stabilizer that samples the output of the oscillator and applies a correction voltage based on frequency shift.

I'm using a L222-28 DEMI transverter and tunes 222-225 for Rx with no issue. All activity is centered on 223.50 calling frequency with exception of one repeater: input is 223.34 and output is 224.94 so 28-30 covers what I transmit since 224.94 is Rx. I also can transmit 222.100 CW/SSB but hardly any stations with other than FM up here. I only use my transverter at low level output (5mw) to drive a 150w surplus amp (which was originally destined for the now defunct 220 service). My two ancient CC 220-11 yagis at 60-foot make working the stations in Anchorage 65+ miles north of me possible. Most of them run 20w FM rigs with mere vertical whips. Mostly there are four of us that have regular contacts: KL7XJ, KL6M, KL4E, and myself. We use is as sort-of intercom for coordination of other bands.

My 15-year-old K1 serial 175 (R.I.P...lightening strike!) with 13.8vdc supply could easily produce 6 watts on 15m, using either a 40/30/20/15m or a 30/15m filter board. Have you attempted re-alignment of the 15m coils (L3, L4, L7, L8)? Have you verified the exact number of of specified turns on the 15m toroids (L11, L12)? It is easy to put an extra turn on toroids (just putting the wire through the center counts as the first turn). That alone will adversely affect the maximum power output.

My K2 has the original jack after many hours of use, but as it happens I have a right-angle plug so there is no long lever to apply force on the internal components in the jack if I tug on the cord accidentally. Some years ago, several others reported excellent results with a right-angle adapter on their K2s - once the damaged jack was replaced. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of mbyrd22 at tampabay.rr.com Sent: Monday, November 23, 2015 6:04 AM To: elecraft at mailman.qth.net Subject: [Elecraft] K1 headphone jack Good morning, I know this is a known issue with some headphone jacks for the K1 and K2s.

I found a surprising result: The microphone wire is a two-conductor wire, consisting of a single insulated conductor and a shield. At the microphone XLR end the single wire is connected to pin 2. At the rig end, this same wire is connected to pin 1 of the eight pin connector. At the XLR end, the shield is connected to pin3 and pin 1, while at the rig end, this shield goes to pin 8. I know that audio gets to the rig with this setup, but it clearly is not what you guys are talking about. I see several alternatives: 1. Remove the shield connection to pin 3 at the XLR; leave pin 2 connected. 2. Remove the shield connection to pin 1 at the XLR; leave pin 2 connected. 3. Get a new cable with two or three conductors inside a shield and still use only pins 1 and 2 at the XLR, using only conductors, not shield. 4. Get a new cable with two or three conductors inside a shield and still use only pins 3 and 2 at the XLR, using only conductors, not shield. Alternatives 3 and 4 leave me the choice of connecting the shield only at the microphone end, or not, depending upon what works best at reducing RFI. I think that this exhausts the alternatives, so if one or both of you can give me a shove in a single direction, I may be able to row out the rest of the way by myself. I gently patched things back together so I can meet my 2000Z sched, but I await further instructions, O Masters of the Universe.

As pointed out in private e-mail, professional installations have migrated to *three wire* plus shield cables with pin 1 connected to circuit return (PTT ground in the case of amateur transceivers) and shield connected to the shell of the connector (chassis) on both ends. However, most analog work still uses two wire plus shield with an XLR plug that ties pin1 to the shell internally. > I see several alternatives: > > 1. Remove the shield connection to pin 3 at the XLR; leave pin 2 > connected. If your cable is a "coaxial" one - a single wire with shield, the best short term "fix" is to connect the center wire from pin 2 of the XLR to pin 1 of the Kenwood/Elecraft Foster plug and connect the shield from pin 3 of the XLR to pin 7 of the Kenwood/Elecraft Foster plug *with no connection to pin 1 of the XLR plug*. In this case the cable is acting as a simple two wire cable. > 4. Get a new cable with two or three conductors inside a shield and > still use only pins 3 and 2 at the XLR, using only conductors, not > shield. If I were using two conductor with shield, I would wire pins 2 and 3 as above and connect the shield between pin 1 on the XLR and the *shell* of the Foster plug. If the transceiver properly bonds the Foster jack to a metallic chassis, the shield is properly terminated on the chassis as it should be. If the transceiver mounts the mic jack to a circuit board on an insulated panel, the shield is floating (isolated) where it should cause no problem. *Under no circumstances* would I connect the shell of the Foster plug to either the mic return (e.g. Pin 7 as done by Heil) or the PTT ground (e.g. Pin 8) as that "circuit' can wind its way many places in the transceiver before it is bonded to the actual chassis (and power supply) return. If replacing the cable, look for shielded, *twisted pair* cable. The twisted pair will help balance out any common mode RF and hum resulting in lower noise even when the shield is floating on one end. 73, ...

To: I've had my K2 #58xx for quite a few years now, but have recently added the KPA 100 amp. I would like to improve the frequency stability. I have read EVERYTHING on the internet about this subject, and have now been experimenting with the PLL frequency compensation board, changing the RA value, with mixed results. Here's my question...I see that the compensation unit varies the voltage applied to the varistors with changing temperature. I am wondering if it would be feasible to replace that unit with one of the huff puff type stabilizers like the x-lock or K4DPK stabilizer that samples the output of the oscillator and applies a correction voltage based on frequency shift.

It works properly as a microphone, but still has extreme RFI on 75 phone. I rechecked my other microphone, a Ten Tec Model 705 with a home made adapter from 4 to 8 pins. That microphone shows the same RFI. I know that my IC-730, tested last week, did not have any RFI on 75 meters, so I am still stuck as to why this is happening. Both the "ugly" baluns (coiled hardline chokes) in this feedline are about 50 feet in length, and both are spiral-wound, not scramble-wound. I will try to do a radial survey on Sunday. I believe that I already tried removing all other feedlines from the antenna tuner, but I will assess that again on Sunday. A field-strength meter in my shack shows RF on 80 when I transmit, but there is some RF on 20 meters as well; there is less RF on 20, but there is absolutely no sign of audio problems. 73, Jan, KX2A From netbsd21 at gmail.com Mon Nov 23 22:45:36 2015 From: netbsd21 at gmail.com (Scott) Date: Mon, 23 Nov 2015 21:45:36 -0600 Subject: [Elecraft] Dead K3 In-Reply-To: <077a01d12630$db1a88d0$914f9a70$@verizon.net> References: <077a01d12630$db1a88d0$914f9a70$@verizon.net> Message-ID: <5653DD60.5040008@gmail.com> Before you crack the chest or of your K3, check the APP connectors on the back.

Elecraft support did respond. I had sent the msg to support at elecraft.com and not the correct address which is k3support at elecraft.com. The test was to disconnect the remove the ATU board and connect the RF board directly to the antenna port - which worked OK - 1.2:1. With ATU installed and auto-tuned, I get 10 watts delivered to the load, so in my case the bypass VSWR is little high, but not really a concern. Since the ATU *is* installed, just tune it and everything works fine.

I have printed out Joe's directions and placed them in the K3 file - for future reference. 2. Is you K3's chassis connector OK - loose ground? 3. Have a proper ground from the K3 to your station ground? 4. You are using the same feedline to test the K3 as used to test the 730? If not - do so. Everything needs to be eliminated. You have now eliminated the problem from causes in your station layout and the antenna/feedline to the K3 - as the complete same using the 730 works fine. True? Then the problem is with the K3 or something attached to it. 5. Disconnect everything from it except power, antenna, and mic. Test it. All clear - the RF is coming in on something other than the mic (plugged into the K3). Problem still there? 6. At this point, try an alternate mic and see if it works. If it works good - the problem is the mic/mic wire/connector. If it does not and you still have RFI - walk away for a while and cool down. Just a few simple steps that would apply to any radio in a similar situation.

True? Not true ... the Icom uses an electret mic, not the dynamic Audio- Technica. If the microphone is wired correctly, the issue is in the antenna system and probably requires improved common mode decoupling. Air wound solenoidal chokes are not sufficient in the most intractable cases *like elevated verticals*. Replace the elevated vertical with a dummy load.

It seems to me that I read an old post from Wayne or Eric (when they announced the BFO mod) that said they would be experimenting with N750 caps in the BFO, but never saw anything about the results. Perhaps I will go that route and try to stabilize the BFO first. Maybe between that and careful selection of RA on the thermistor board (to stabilize the PLL) I can achieve some improvement. Just a note...the rig doesn't drift excessively and is probably within spec, but there is room for improvement ----- Paul, N2PD -- View this message in context: http://elecraft.365791.n2.nabble.com/Using-X-lock-to-stabilize-PLL-osc-tp7610743p7610787.html Sent from the Elecraft mailing list archive at Nabble.com.

Thanks to W4TV and W3FPR for intelligently moving the discussion back on track. Questions: EXACTLY what is the configuration the the "vertical antenna? Quarter-wave with radials or half wave without radials? How many radials? How long? Where is the antenna feedpoint with respect to the radio? What coax are you feeding it with? Are you SURE that the connectors at both ends are properly installed and gas-pliers tight at both ends? Is there a short, fat copper bond from chassis to chassis between every piece of gear in your shack? Is there short fat copper from there to all the other grounds in your home? Joe is exactly right -- ANY "balun" that isn't multiple turns of coax around a #43 or #31 ferrite core is USELESS at HF. Those "string of beads" "baluns" sold by various vendors are badly misguided copies of the W2DU design, which what a very good design that used a LOT of #73 beads. Joe is also exactly right -- the ONLY proper connection of a cable shield is to the SHIELDING ENCLOSURE of the equipment it feeds. The cable shield should ALSO be bonded to the shielding of the microphone. Some fundamentals: ANY antenna that "works" will put RF in the shack -- it does that by radiating RF. An antenna that lacks an effective common mode choke will ALSO put RF onto the feedline. Summary of suggestions/comments: Answer the questions I asked above. They are all important. Download and STUDY k9yc/com/RFI-Ham.pdf and http://k9yc.com/GroundingAndAudio.pdf Follow these instructions carefully. I suspect that the cause of Jan's problem is failure to properly connect cable shields, and/or to bond all the gear together. 73, Jim K9YC On Tue,11/24/2015 6:54 AM, Joe Subich, W4TV wrote: > Not true ... the Icom uses an electret mic, not the dynamic Audio- > Technica.

The 100w PA pulls off its current ahead of the fuse and diode so using the front panel is not indicative of the voltage of the current going to power amp. Hang a voltmeter on the APP if you want accuracy. Incidentally the polyfuse will permanently change cold value after interrupting for the first time so there is another variable. 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Joe Subich, W4TV Sent: Tuesday, November 24, 2015 9:31 AM To: Robert Nobis; Elecraft Subject: Re: [Elecraft] K3 Voltmeter calibration ... > You could easily drop 0.2 volts in the cable depending how long it > isand the gauge of the wire.

Go into the CONFIG menu, set Tech mode "On", then go to the "ADC REF" setting. Note what it is before changing anything, in case this adjustment affects anything else adversely. Adjust the ADC REF value to cause the voltmeter display to read the value you want. You will need to go in and out of the menu display to see the results (kinda clumsy). Again, this adjustment may affect other measurements, so an accurate K3 voltmeter may not be that important after all. 73, Brian, W6FVI On 11/24/2015 9:32 AM, Joe Subich, W4TV wrote: > > It matters not if there is a series diode.

I connected one of the terminals to the vertical and the other to the ground base. The result was an SWR a little lower than with the hardline, patched-together feedline, but RFI when I run power.

On page 53 of that manual it has the following description for ADC REF and how to calibrate it. ADC REF Allows calibration of the voltage reference used by the K3 to measure and display certain values, such as the rig's supply voltage. (Optional.) First, disconnect anything attached to the ACC jack. Next, locate the ADC REF menu entry. It will initially show 5.00 volts as the reference voltage. Using a DMM set to DC volts, measure the actual voltage at pin 2 of the ACC jack. This must be done while the ADC REF parameter is being displayed. (Note: The (-) probe of the DMM should go to the K3's chassis ground, e.g. at the GROUND lug.) Finally, use VFO A to set the ADC REF menu parameter to what you measured at pin 2. So you need to set ADC REF to the voltage on pin 2 of the ACC jack. NOT what is at the APP connection on the RF board. 73, Mark Musick, WB9CIF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Brian & Cyndi Sent: Tuesday, November 24, 2015 11:19 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 Voltmeter calibration ...

For the moment, I am using the E980297 cable to go to the P3 and then the P3 to the computer. I also have a Y at the computer with a cable going to the CAT input to the Acom 2000A amplifier. Acom says they get serial data from pins 1 and 5, but the logging program is what talks to the Acom. I have not figured out the ramifications of this, but I am temporarily not using the K3CAT feature with the Acom as it has not been reliable. So, If I wanted to use the USB interface to take advantage of the sound board options, I could use the CBLP3Y for the P3. But how can I communicate with the Acom?

Make sure you are only listening and not hooked up to send data to the P3/K3 via this path. We basically take the USB comm data between the K3 and the computer and then echo it out the RJ45 CBLP3Y connector to the computer input DB9 on the P3. The other connector on that cable returns the P3 data to the K3, along with the computer data.

When it happened, I was running a frequency, and I would go into TX sometimes before the P3 would unfreeze and the P3 would display my TX peak, following my modulation. Seemed to maybe happen at some transition of the P3 going back to RX when I keyed the microphone. Also noticed sporadic freeze decay of P3 after stopping TX. Most times it switched to RX right away, but sometimes it hung up for a second or two. I thought I was seeing things! Any ideas out there?

The results: PLL drifted 50hz UP, and the BFO drifted 60 hz DOWN. Perfect for the higher bands where they almost cancel, but not so for the lower bands where they add (do I have that right?).

Hi Jim, Sorry for the confusion. I'll pull everything into this post to put it in the correct context: Problem: 6M band -> VSWR 1.8:1 (KX3 meter) on 50ohm load connected directly to ant connector (no cable). ATU - bypass mode Load verified good. All other bands good. ATU will match to 1:1 if enabled and tune requested. After ATU match, 25ohm load yields 2:1 (KX3 VSWR meter test - OK). So the issue was that the ATU in bypass mode on 6M into good load gives a 1.8:1 VSWR. Working with Elecraft support, I removed the ATU board to check VSWR w/o the ATU in the line. That checked good 1.2:1. The ATU in bypass mode on 6M does not quite function as a 50 ohm transmission line. For my particular unit, it was higher than expected. 1.4:1 is considered OK. If the ATU is enabled and tune is engaged, it has no problem matching the output stage to the load and delivering rated power. So, operationally not really an issue. Just leave the ATU enabled and tuned. The reason for going into bypass mode was to perform a TX gain cal procedure, which specifies the ATU must be set to bypass. I used the KX3 utility to do this and it sets the ATU to bypass and steps thru each band. When it got to 6M, it failed - probably because the foldback circuit was kicking in @ 1.8:1 and/or the output stage can't deliver the 6 watts need to complete the cal into that mismatch. Doing the cal manually with the ATU on and matched for 6M band works fine. Hopefully, this provides a more useful note for anyone else that may have a similar issue. Trying to contribute back to the list - as I have learned a lot using this resource.

M4 memories can be used on each of the bands to store information. For example, on 20 meters you might program M1 to 14.000.00 CW, M2 to 14.070.00 DATA, M3 to 14.150.00 USB, and M4 to your favorite 20 meter net frequency. Because these are per-band memories, you can use M1 ? M4 again on other bands. Storing a Per-Band Memory 1. Set VFO A and VFO B frequencies and other information to be stored (CW, SSB, antenna, pre-amp, attenuator settings, etc.). 2. Tap V>M and then tap M1 ? M4. Recalling a Per-Band Memory 1. Tap M>V and then tap M1 ? M4. Erasing a Memory 1. Select the memory to be erased by tapping V>M and rotating VFO A to the memory to be cleared and then tapping CLR. You cannot clear the M1 ? M4 quick memories this way. These can only be reprogrammed.

You can also use the Memory Editor program from your PC. I enjoy using the program because it is fast and it presents all of the data in a nice spreadsheet-like format. It also saves the data in a file. And the help feature really goes into detail about how to use the K3 memory features. http://www.elecraft.com/K3/FreqMemEdit/K3_Freq_Mem_Editor.htm 73, Mike K2MK charles-2 wrote > Just got my K3S yesterday and spent most of the night setting up the > menu and config selections.

I resolved the RFI and distortion problem with my 67 foot vertical on 75/80 meters. The difficulty was, as some suggested, with the station ground. I should have realized that 20 years of a wire clamped to a copper rod exposed to the elements would probably result in some oxidation. I removed the clamp and used steel wool to scour the rod, the inside of the clamp, and the wire (I do not remember the exact size, but it is substantially larger than #10). I put everything back and now I no longer have audio oscillation nor spikes on the SB-610 scope. When I first put things back together, I forgot to ground the K3 itself, but the audio was clean. I suspect that the corroded ground acted as a semiconductor that detected the RF. Anyway, the purists among you can relax, I attached the ground to the K3 and it still works. In my usual fashion, I chased down the cheap solutions before the costly ones. At this point, I am using the 50 ohm feedline with the commercial 1:1 balun, but, weather permitting, I may try the hardline and chokes again (cheaper that way). I want to thank the many hams who responded to my call for help and gave me plenty to chew on. I especially want to thank Joe, Phil, and Bob, although everyone's input helped.

From there you can change your email preferences. My recommendation is *not* to receive the digest, but to receive individual emails *and* then on your email client, set up an Elecraft folder under your Inbox. *Then* create a filter that moves any email with [Elecraft] in the subject line to that Elecraft folder. You will be left with your own personal "digest" where you can respond to individual emails or delete them as you choose rather than dealing with the digest as a whole. 73, Don W3FPR On 11/25/2015 8:59 PM, Byron Peebles wrote: > I don't see how to switch from "every message" to Daily Digest. > Do I need to register a second time and somehow delete my previous > registration? > From w4rks73 at gmail.com Wed Nov 25 23:37:39 2015 From: w4rks73 at gmail.com (James Wilson) Date: Wed, 25 Nov 2015 22:37:39 -0600 Subject: [Elecraft] P3 Showing Transmit Signal Message-ID: This has been mentioned before but - if you want to consistently see your own signal (for adjusting audio, compression, Etc.) Here's how: Transmit a SSB signal into - say, a dummy load - and while in transmit mode, do a reset on the P3. ( I have one of the function keys set for a handy RESET.) When the P3 comes back on, the switch signal for the P3 has already been sent and the P3 comes up showing your own signal. Handy!

My Thanksgiving Eve was great when the UPS man walked up and delivered the long desired KX3. I spent the next few hours putting the kit together and it felt like it went together without a hitch. I then decided to make my first QSO and wanted it to be DX so I worked a bunch of stations in the Carribbean on CW and it was great. I worked a few more this morning as well. I decided to test out SSB....and seem to be running into an issue. I don't think I am getting any power out. When I key the Elecraft mic, the TX light does come on but the power meter does not show any output. I see one vertical bar above the RF initial on the RF meter. It does go up higher (to 12) when I am on CW. The SWR meter does not show any vertical bars when trying to transmit on SSB. I get one one bar when I transmit on CW. My ANT is a Steppir vertical so it is resonant on the frees. I am powering it with an Astron power supply that I used on my 100W rigs...so I think I am fine there. I did follow the steps on page 15 of the operating guide to setup Voice....no luck. Any ideas/thoughts would be greatly appreciated. 73 de Keith KB3ILS From ktalbott at gamewood.net Thu Nov 26 09:41:14 2015 From: ktalbott at gamewood.net (Kenneth Talbott) Date: Thu, 26 Nov 2015 09:41:14 -0500 Subject: [Elecraft] Need a KFL1-4 Manual In-Reply-To: <000301d12822$830a6270$891f2750$@net> References: <13508547.1448521353302.JavaMail.root@elwamui-rustique.atl.sa.earthlink.net> <000301d12822$830a6270$891f2750$@net> Message-ID: <005d01d12858$80f94d30$82ebe790$@gamewood.net> In my experience, the employees at Elecraft are in a class by themselves.

Remove it and plug it in again. Did you turn on bias? The MH3 needs that to be on. Do you have your mic gain set to a high value? If so, turn it down to a low level - set compression to zero initially. Then bring up the mic gain until you see 5 to 7 bars illuminated on the ALC meter - that is the correct audio drive for voice modes. Once you have achieved that indication, you can add a bit of compression - 3 to 6 dB is the usual range, too much and you will distort (you have heard those signals on the air during a contest). Set the desired power with the power knob and you should be 'good to go'. 73, Don W3FPR On 11/26/2015 9:33 AM, kb3ils at comcast.net wrote: > I decided to test out SSB....and seem to be running into an issue.

Amp was built from CCI kit: http://www.communication-concepts.com/140-watt/ And built on 1.5x5.5x6 inch heat sink with 5.5x11x3 inch custom chassis. I added 4-inch fan controlled by thermistor and added a RF output 10-bar LED meter (forward power only - front panel switch removed). It has a 7-pos rotary switch for selecting LP filters which are not installed (I built the CCI's LP filters but could not get low SWR thru them). PowerPole No. 10awg six-foot power cord included. I tested 2nd harmonic on 40m at -45dB and at 20m at -40dB running 100w output into 50-dB attn into my HP141T spectrum analyzer with added 20-dB attn. I recommend not running over 120w which is easily does with 2.6 to 4.5w drive depending on band (I can supply spreadsheet with measurements). http://www.kl7uw.com/AN762_SN0001_front.jpg http://www.kl7uw.com/AN762_SN0001_Inside.jpg http://www.kl7uw.com/AN762_SN0001_rear.jpg http://www.kl7uw.com/AN762_SN0001_top.jpg I have about $370 in materials into this project. $225 with Free flat-rate shipping to US.

It takes the form of various buzzy spurs evenly spaced across the band and quite easily seen on another SDR. Even with just a power connector and no other leads connected I got this QRM. I was told this was normal and had to be expected with the switched mode regulators inside the PX3. Putting my hand near the screen of the PX3 made the noise stronger and louder, but sometimes putting pressure sideways on the DC power plug would almost eliminate it, unfortunately as soon as I released the pressure it came back again. I almost considered hiring someone to hold the plug for me while I operated the rig ;-) Getting totally fed up with this annoying noise, especially as one of the spurs was on 144.300 the SSB calling channel, I decided today to see if I could improve the situation, and I have. I had already checked that the DC Jack was grounded properly to the side panel. However what I hadn't appreciated is that the common of the PCB is connected to a switch in the Jack and is not directly connected to the chassis of the Jack. What was happening was the barrel of the plug was connecting to the pole of this switch and the PCB common, but only loosely to the chassis of the Jack. Movement of the plug sideways with enough pressure did connect the plug better to chassis and resulted in the noise going away. I opened up the back of the PX3 and connected the chassis part of the Jack to the PCB common side of the jack's switch by soldering a small piece of copper EMI tape across the gap. This ensures that the PCB common is stoutly connected directly to chassis at the DC Jack. This has had the desired effect, no more intermittent increases in spurs heard in the receiver as the leads are touched or moved, and no forest of spurs visible on the SDR when I turn on the PX3. I can now listen to relaxing white noise on 144.300 now without having to put the notch filter on to remove the heterodyne ;-) The usual caveats apply, don't do this modification unless you need to, and only then if you know what you are doing, take anti static precautions, and accept that it may or will invalidate any warranty you may have with Elecraft. 73 from David GM4JJJ From pmeier at me.com Thu Nov 26 17:39:44 2015 From: pmeier at me.com (Pete Meier) Date: Thu, 26 Nov 2015 15:39:44 -0700 Subject: [Elecraft] FS:KXPA100/AT100 Message-ID: For sale KXPA100 with internal automatic antenna tuner and includes KXPACBL to interface with KX3, manuals and original box.

I don't recall a audible tone, but it's possible. The K2 alone is spec'd down to 9.5 VDC supply, but at reduced output as follows: 9.0 V min for 2 watts out 9.5 V min for 5 watts out 10.0 V min for 7 watts out 10.5 V min for 10 watts out While you may be able to get more than the indicated power out for a given voltage, IMD will increase or other issues may crop up. The manual says to "monitor transmitter output signal". The KPA100 is spec'd for a minimum voltage of 11.5 volts. AFAIK, the warning level is not adjustable. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Chris Kimball Sent: Friday, November 27, 2015 7:19 AM To: elecraft at mailman.qth.net Subject: [Elecraft] K2/KPA "Low Batt" warning and beep I'm checking my K2/KPA rig as the battery runs down.

Very strange, and extremely interesting. While it was ongoing, both 40 and 80 were open across NA. Those of us with very good antennas for 80 and 40M, and especially those with directional RX (either a beam or Beverage) are well aware of long path openings at certain times of the day.

Those of us with very good antennas for 80 and 40M, and especially those with directional RX (either a beam or Beverage) are well aware of long path openings at certain times of the day.

I fed the AA-54 into a Alex Loop inside the house and had the KX3 connected to my mini-G5RV outside. I set the AA-54 to do continuous spot measurements at approx 14.082MHz. In this mode the AA-54 excites briefly approx once per second at the chosen frequency. Using HDSDR connected to the I/Q output of the KX3 via computer in CW mode I observed a pulsing signal peak at 14,081,530Hz. In LSB mode I observe the signal peak 14,082,127Hz. In AM mode I observe the pulsing peak on HDSDR at 14,071,114Hz. I get the difference between the first two measurements (600Hz side-tone), I don't understand the results for AM display. Now if I tune the KX3 manually and listen for the signal I get the following, LSB strong S9 1KHz pulsing tone at approx 14,082,600, CW strong pulsing tone S9 zero-beating tone at 14,082,108 and finally AM weak peak (S2) pulse at approx.14,081,800Hz. These measurements make more sense but don't explain what I'm seeing using HDSDR monitoring AM obtained from KX3 I/Q.

I'm fuzzy on the details, but The KX3 can function either as a zero-IF receiver or essentially as a more or less 8 kHZ IF, which can trade some problems for others. My theory is that in your setup, with AM the IF is moved, and your external decoded didn't get the memo. 73 de n1dam From rcrgs at verizon.net Fri Nov 27 21:19:09 2015 From: rcrgs at verizon.net (Robert G Strickland) Date: Sat, 28 Nov 2015 02:19:09 +0000 Subject: [Elecraft] (K3) need help with cw keying - right now Message-ID: <56590F1D.6080007@verizon.net> All of a sudden and for whatever reason, when using my Vibroplex hand key [3-pins], all I can get is an automatic "A" that keeps repeating, in either paddle direction.

But it is more likely that it is a ducted signal in the magnetosphere. The actual delay varies with geomagnetic latitude, and the further south one is the closer the delay time is to 1/7 second. Such signals can be trapped in occasionally occurring, tubular magnetospheric ducts, which stretch from the northern to the southern hemispheres along the Earth's magnetic-field lines. I wrote about it in QST in 2009 - http://folk.uio.no/sverre/papers/2009_MagnetoDucting-QST-LA3ZA.pdf. There was also an excellent article about it in Radcom by P. Martinez (G3PLX), "Long Delayed Echoes, A Study of Magnetospheric Duct Echoes 1997-2007," Radcom, Oct 2007, pp. 60-63 (not on the web to my knowledge). I have an analysis of several such medium delayed echoes or magnetospherically delayed echoes (MDE), including that of G3PLX, here: http://la3za.blogspot.no/2010/03/magnetospherically-ducted-echo.html The echo time can be predicted from latitude, so if I get more data, I can run my program to estimate the delay time for a given place at a certain time (geomagnetic latitude rel to geographic latitude varies with time). ----- Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog: http://la3za.blogspot.com, LA3ZA Unofficial Guide to K2 modifications: http://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html -- View this message in context: http://elecraft.365791.n2.nabble.com/LDEs-Long-Delayed-Echos-tp7610884p7610886.html Sent from the Elecraft mailing list archive at Nabble.com.

For my CW work it was fine as is, but with WSPR it should be as close as possible. The WSPR software includes a small suite of programs to help make offsets in WSPR for the dial frequency of the KX3, making the actual receive and transmit frequencies extremely accurate - within a few hertz. I'm trying to locate someone with a KX3 who has used those FMT programs for their WSPR operation. The measurements I've gotten look suspicious to me. I've posted a question on the WSJT Yahoo group and even emailed Joe Taylor K1JT about it, but so far I've gotten nada. Anyone...?

Yes. Peter was the father of AMTOR, one of the most fun modes there ever was, in my opinion. Too bad it died off, especially when today's rigs would handle it so well. The throughput rate was just right to keep you humpin' on the typing and carry on rag chews lasting as long as you didn't run out of material to chew on. ;) By the way, the AMT-1 was his design, if I remember correctly, and built by AEA, who also built the big PK-232.

To my knowledge, there is no basic difference between Sitor and Amtor. Only the name is different. I remember when working for Microlog Corp back in the 70's, when we were developing the SiTor terminal programs, we'd (illegally to be sure) fire up the TR-7 on the marine 12 MHz band and call marine coastal stations to check out our operating program, asking for radio reports etc. We knew most of the ops, so nobody cared too much. Especially if the network was quiet for a while before we called. Curiously, the TR-7 IS fast enough to successfully operate Mode A Amtor. Since there was a several month lead time for ads in QST, I remember getting the inside scoop that the FCC was about to OK the use of both Mode A (hand-shake) and mode B (Forward Error Correction) Sitor, or Amtor if you please on the HAM bands. The ad was scheduled to come out in the issue of QST, the same month the FCC OK came out. This was the "Now, you can chirp back." Ad and boy was I sweating bullets that the OK would in fact come out in time. Luckily for me, it did so I avoided a huge "egg-in-the-face" situation. It was quite a challenge back then to find radios that would switch (from full power transmit to full sensitivity receive) fast enough to run mode A. This was not break-in CW because almost all the programs used AFSK with the rigs in SSB mode.

The factory defaults work great, I used them for several years before digging into the menus. I recommend you separate the screws, nuts, and lock washers into separate bins by size, a muffin tin or egg carton works well, just don't put ESD sensitive components into Styrofoam. Go slow [this is not a sprint], ban the vacuum from your shack until done, and defer working on it after a beer or a glass of wine. :-) Just follow the build instructions exactly, and no fooling, check them off. If your concerns are about shack wiring and usage after build, consult this group, be as specific as you can [I recommend one question at a time, it seems to lower the hijack rate of your need]. If you've got locals, go there first. Feel free to ask me why I know this.

There are no shortcuts. If you're buying the kit or assembled version first step always is to read the manuals, both assembly and operators. They're free for the downloading from the Elecraft site. I would also add Fred Cady's books on the K3 to the required reading list. If after reading all you can from these good sources on the K3 you still feel the need for help then this mailing list is available. If this is your first Ham Radio ever you need to spend some time with the ARRL Operating Manual before ever getting on the air. The K3 is possibly the most configurable radio ever built. You will be doing yourself and it a disservice by jumping before looking.

The "official" name for SITOR is NBDP (Narrow Band Direct Printing). San Francisco Marine Radio (Station KSM) transmits press and weather on Saturday afternoons using both RTTY and SITOR My PK-232 decodes SITOR when used in AMTOR mode when I can get a decent signal on their 8 MHz or 12 MHz frequencies.

Your new rig will come out of the box ready to TX, but you will need to hook up a paddle, mic, computer, and antenna. Like any complex piece of gear, the first move is ALWAYS to STUDY THE MANUAL. It will tell you how to hook stuff up to the radio, how the controls work, how the meters work, etc. This is vital stuff, so take your time with it. You can even get a running start by downloading the manual from the Elecraft website and studying it while you wait for UPS. :) Yes, there are menus and options, but they mostly are for things you add to the radio, or different ways you want the radio to work. Leave this stuff for later. 73, Jim K9YC From ron at cobi.biz Sat Nov 28 23:04:07 2015 From: ron at cobi.biz (Ron D'Eau Claire) Date: Sat, 28 Nov 2015 20:04:07 -0800 Subject: [Elecraft] Final attempt at SOS !!!!

One morning before heading to work I was pointed toward the setting moon looking for JA or UA0. As I tuned around I heard a CQ. As I listened for the call, I heard another CQ on a slightly different frequency. "Wow" I said to myself, "this is amazing." As I continued to listen, I identified W5UN on one frequency. I had worked Dave several times, even on SSB, so I passed on him and tuned to the other guy. He was also W5UN! I was hearing Dave off the back of the antenna on tropo (950 miles) on one frequency and off the moon with some Doppler and a 2.5 second time delay on another frequency.

The K3S is usable out of the box. The best way to use it is to connect it per the manual then use it. Over time you will find things you wish to tweak.

If reflock is turned on, moving the dial will only get the the response "reflock" from the vfob lcd line" and will not change the frequency The solution is hidden away in the "K144XV REFERENCE OSCILLATOR PHASE LOCK OPTION MANUAL ERRATA Rev. A1-1, March 22, 2013" document (30 months old!) why it is still there after all these years and hasn't been put in the manual proper only Elecraft know... I have already helped 3 UK amateurs who have had the same issue!- "Tune the K3 to any frequency in the 2-meter band. Hold CONFIG to access the CONFIG menu and select XVn OFS, where n is the transverter number you assigned to the K144XV (see Enabling the K144XV Module in the K144XV Installation and Operation manual). <<<<>>>>>>>>. The automatically calculated offset will appear in upper half of the K3's LCD. This enables reflock for both the 144 and 146 MHz band segments. You don't have to repeat the procedure for each segment."

In the last year I?ve built: KX3, KPA500, KXPA100, PX3, W2, KAT500, K3S and a P3. Best advice I can give is to make a place/space where you can separate all of the parts into understandable cups or trays, or something of your choice, and then label them. You?ll be dealing with lots of small screws and nuts and washers. Many look a like, but they?re not. I used my wife?s muffin trays ? couple of them ? and then you can quickly separate everything before you begin assembly to make sure when they call for a specific screw and a specific washer, you?ll know where they are in an instant. Know the Elecraft assembly manuals are very good. Really first class. They do ship a black-and-white manual, but I believe the download PDF is a color manual which does help in some rare instances. Best of luck with your K3S. Do not hesitate to reach out on this list or directly. Happy to assist.

I operated the CQWW CW Contest in "holiday mode", which means when the family was otherwise occupied and I wasn't, I'd hop on the radio for a few contacts. With a couple of late hours on 40 meters each night, and some spinning through the cluster spots, I was able to make about 400 QSOs in very few hours. I felt pretty good about that considering I'd sold my Alpha 9500 to bring in the KPA500 and KAT500. My Sunday was otherwise occupied or the numbers would have been significantly higher, since you really don't tire when listening to this receiver. It felt really good to break a pileup on something distance, like D4C or CE0Y without the legal limit. With the 8-pole filters the receive is amazing, even in crowded band conditions. I viewed this as a weekend of practice with CW and the radio and I feel better about my abilities with both. I have more to do, of course, but I viewed the weekend a success and my decision to upgrade to the K3S a great one. 73, Byron NZ3O From n7tb at arrl.net Sun Nov 29 22:17:13 2015 From: n7tb at arrl.net (n7tb) Date: Sun, 29 Nov 2015 20:17:13 -0700 (MST) Subject: [Elecraft] Horizontal Loop question Message-ID: <1448853433182-7610926.post@n2.nabble.com> I currently have a horizontal loop at my QTH being matched by an Icom AH-4 Tuner. It is interfaced with my Icom 756. I will be running a new-to-me K2 with the auto tuner installed. Right now, the loop is connected at its end points to 450 ohm ladder that has one leg attached to the tuner's antenna connector and the other leg to the ground lug. Coax comes from the tuner to my rig and works great on my Icom 756. Now for the several questions. 1. the AH-4 interfaces with the 756 via a four conductor molex connector. Is there some way to take those 4 wires and interface them to my K2 and let the AH-4 tune the loop instead of the internal K2 tuner? 2. I presume it possible to take the coax feed from the A-4 off my 756, or have an antenna switch do that, and attach the loop coax feed to my K2, then turn on the 756 to the same frequency that I want to transmit on the K2, and press the tune button on the 756 to tune the loop? 3. I could manually take 450 ohm loop antenna connection off the Ah4, attach it to a balun attached to another length of coax that attaches to the K2, but this is very cumbersome. Perhaps an antenna switch is available that has two balanced feedpoints and a coax feedpoint that would allow me to switch remotely? Does anyone know of such a thing? 4. If I decide to feed the 450 ohm twin lead to coax to my rig, what type of balun do I need? 4:1 or 1:1? Thanks so much for all you help.

In-Reply-To: References: Message-ID: <565C4DE2.9090708@embarqmail.com> Cotter, Yes, it is as easy as changing the turns spacing on L1 - but you will have to squeeze the turns rather than spread them. Do to the mixing scheme, tuning the VFO to a lower frequency raises the output frequency. Be aware that the lower frequency may not be consistent from band to band. That is due to variation in the exact frequency of the crystals on the band board, so plan a bit of coverage just below your desired low frequency limit. 73, Don W3FPR On 11/30/2015 2:56 AM, Cotter W.

For the balun, the impedance at the shack end will determine whether a 4:1 or a 1:1 will be a better choice. Measure the impedance on all bands of interest with an antenna analyzer and use the results to figure out which will be the better compromise. The antenna feedpoint impedance will change from band to band, and the length of the feedline will transform that impedance to something else. If you have trouble matching it on any one band, try adding or subtracting 1/8 wavelength of feedline for that particular band and measure again. 73, Don W3FPR On 11/29/2015 10:17 PM, n7tb wrote: > I currently have a horizontal loop at my QTH being matched by an Icom AH-4 > Tuner.

You can also swap the VFOs, then swap them back before transmitting, but if you lose track of which is which in the 'heat of battle', the UP cops will admonish you. To listen to both VFOs simultaneously, you need to install the subRX. 73, Don W3FPR On 11/30/2015 7:16 AM, simon m0vky via Elecraft wrote: > hi > > recently purchased and built a k3S, without the SUB RX. > i was under the impression that you could RX on the same band but on > VFO A and VFO B. > ie, to RX the DX QRG and RX the pile up when working split. > this appears not to be so. > do i need to buy the SUB RX board to be able to do this or am i not > doing something correct?

Signals follow earth magnetic field - bouncing back when they reach the southern hemisphere - and the delay therefore depends on your magnetic latitude (distance from the magnetic pole). It is quite a long path and for my QTH the delay is 237 msec which is so long that it is easy to hear your own echo with any modern rig. In fact you would think someone is jamming you until you find out its yourself! The phenomenon has been researched and is well understood. It seems to occur around winter solstice and I have heard it several times, mostly 4 to 5 hours after sunset. I wrote an article about it in QST Nov 2009 (Observation of Long Delayed Echoes on 80 Meters) and I can send you a copy if you mail me off-list. I can also send you an audio recording so you can hear what it sounds like. Anyone else who wants a copy (article and/or sound recording) please contact off-list. Good luck - I expect chances will be best on 80m in a few weeks time from now on until around February. 73/Paul OZ4UN Sent from my iPad > On 28 Nov 2015, at 04:38, Dauer, Edward wrote: > > I just finished reading Eric Nichol?s (KL7AJ) book titled Radio Science > for the Radio Amateur, in which LDEs and other non-linear propagation > events are discussed (ch. 11).

A 3 foot piece of coax goes to the tuner (this coax should be as short as possible). You will find that the Elecraft tuners will cover a broad range. Mine covers all bands excluding 160. Actually it will tune 160 but with an amplifier, I expect extremely high voltages at the balun. On 160 you could tune it against ground if so inclined... The antenna is a delta loop with the top at 120' in a pine tree. The bottom wire is at about 50' and it is fed about 1/3rd up a vertical side. It is an excellent performer and depending on where the lobes are on the higher bands, it sometimes beat my 3 element tribander. On 40 it really shines. There is much written on the net on current baluns vs voltage baluns and 1 to 1 vs. 1 to 4. Also, much is written on common mode current.

When connected to a computer, that cable will be assigned a virtual serial port by the computer - just like any other USB to serial device. Plug that cable into the KX3 (or the PX3 if you have it) and tell whatever software application you are using to use whichever COM port has been assigned by the computer.

Connect it from a USB port on your computer to ACC1 on the KX3 (described on p. 5 in the KX3 manual). You can use the KX3 Utility to test the connection (I think you have to close the com port after testing it with KX3 Utility. Otherwise N1MM will think it's still in use). Go into the configure ports screen in N1MM and set COM3 to work with a KX3 (pulldown list) and click the SET button to set up the serial communication parameters. The latest version of N1MM even suggests the proper settings to use for a KX3. Not the most complete description, but I'm at the office and working from memory, which is always dangerous for me. I think you should be able to get it running with this procedure. You'll know it's working when you see the KX3's frequency displayed in the upper left corner of N1MM's main window.

I received many directly to my email address. I came away many great ideas. One is to get ELNEC and use it! I am sorry I did not elaborate about the size of my loop. It is 60 feet on a side, fed on a lower corner (the other three are in trees) with 450 ohm ladder to my AH-4. I was given the following information for finding an interface for the AH-4 that will interface with any radio. I thought others who may be feeding antennas with this tuner and wanting to interface a non-Icom rig to it might find the link helpful. http://www.ebay.com/itm/ArtCraft-Electronics-AEAH-4-Icom-AH-4-Antenna-Tuner-Interface-/291613533877?hash=item43e58566b5. ArtCraft Electronics sells them directly on their website. I think they build to order mostly. Using the interface is the simplest solution for me, so I ordered one.

Jim, Keying is an entirely different situation than attempting to use the rig control features of N1MM that you asked about. Such nit-picking is necessary for clarity in my mind - i.e. controlling the KX3 does not include keying it. I believe N1MM allows you to set up a different COM port for keying separate from the rig control (I don't know that for sure because I do not use N1MM). If it insists on using the same COM port and uses RTS or DTR for keying, you cannot use the KXUSBa cable since you cannot get to the RTS or DTR signals. Instead use a USB to serial adapter (the Elecraft KUSB is recommended) - and obtain the KXSERa cable (Serial to KX3 cable). Then from the KUSB cable, break out the RTS or DTR signals and make up a "simple one transistor keying circuit" (do web search for details) and use the output of that keying circuit to key the KX3. If N1MM does allow you to use a different COM port for keying, you still need that different COM port (or USB to serial adapter) - apply the RTS or DTR signals in that port to the one transistor keying circuit and take the output of that circuit to the KX3 key jack. 73, Don W3FPR On 11/30/2015 1:25 PM, James Rodenkirch wrote: > Don - I can change bands with N1MM BUT when I select the F1 CQ button I get this -- "no CW port is selected in Config" > > ________________________________________ > From: Don Wilhelm > Sent: Monday, November 30, 2015 11:20 AM > To: James Rodenkirch; elecraft at mailman.qth.net > Subject: Re: [Elecraft] How to make the KX3 controlled by logging sofftware like N1MM?? > > James, > > The KX3 comes with the KXUSBa cable (USB to 3.5mm plug). > When connected to a computer, that cable will be assigned a virtual > serial port by the computer - just like any other USB to serial device. > Plug that cable into the KX3 (or the PX3 if you have it) and tell > whatever software application you are using to use whichever COM port > has been assigned by the computer.

When the ATU menu is set to CAL, the L and C elements in the KAT100 are bypassed. There may be some residual L and C in the PC traces and relay contacts, but that should be minimal. Yes, you can use the TUNE button and observe the SWR on the K2 as you tune the loop. Be aware that the TUNE with the KPA100 in-line and powered will be at 20 watts unless you set the power knob to a lower level. 73, Don W3FPR On 11/30/2015 2:20 PM, Brian - N5BCN via Elecraft wrote: > I've recently acquired a magloop that will be used with a K2/KPA100/KAT100 > and I wanted to double check my tuning procedure. > > My plan was to tune the KAT100 into a dummy load (ATU in AUTO mode) and then > place the ATU into SWR (x.x-1) mode.

Plus you'd be experiencing significant line loss on your feed if the SWR wasn't right. That's two major drawbacks of your plan. I would suggest that bypassing the KAT100 and tuning only with the controls for the magloop is a far better way to go. A mistuned magloop will also show substantial LOSS at the desired frequency so all tuning should happen at the antenna for best operations. First peak the receiver noise as you adjust the antenna controls, then apply only enough power to get a response from the SWR meter (say 5-10 watts); fine tune the antenna controls for a good match. Do NOT use the tuner in the radio. I was given one, have tried it and frankly I'm unimpressed with the operation and performance. I was hoping for better as it would make a nice RV antenna, but a dipole works MUCH better. If it is all one can manage (HOA or lot limitations), it works but it is so narrow that typical S&P ops are rather challenging, you're never tuned for that new frequency. As one that changes bands often and quickly, it would severely hamper how I operate. Tuning requires patience and time on the lower bands, even a 20 KHz frequency change requires retuning. But the bottom line is that in this case you must tune the ANTENNA, not match it externally. Good luck! 73, Rick wa6nhc On 11/30/2015 11:20 AM, Brian - N5BCN via Elecraft wrote: > I've recently acquired a magloop that will be used with a K2/KPA100/KAT100 > and I wanted to double check my tuning procedure. > > My plan was to tune the KAT100 into a dummy load (ATU in AUTO mode) and then > place the ATU into SWR (x.x-1) mode.

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 radio is only several months old and I don't think the control is the problem. Any Ideas.

For exactly the same reason, it is a highly compromised miniature antenna. I have the model 100 on my truck. But I keep a manual tuner and all band dipole with feed lines and a CCM in the RV... except most of the time the trees are too short to be of value. :-\ Rick nhc On 11/30/2015 3:46 PM, Bill Frantz wrote: > I had the same experience with the Little Tarheel II on my 4Runner.

You can adjust it with the RefCal menu entry. See the "Frequency Calibration" section of the P3 Owner's Manual.

Comer Sent: Monday, November 30, 2015 6:41 PM To: elecraft at mailman.qth.net Subject: [Bulk] [Elecraft] Re Elecraft] Crackling in Headphones I have noted a similar Cracking in the speaker when listing to AM broadcast station KFI (640 KHz). 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.

So with an antenna appreciably smaller than 1/2 wavelength, a very narrow bandwidth is something to celebrate! The only way to increase the inherent bandwidth of a physically small antenna is to increase the resistive losses where RF is wasted as heat. Ever since Maxwell set down his equations unifying electricity and magnetism in 1865, those equations have been proven correct. 73, Ron AC7AC
