Message-ID: I've been using an AFEDRI SDR as a panadapter for my K3 for about a year now using HDSDR. I use it every day but when I powered things up yesterday, the panadapter connection has suddenly experienced a lot of attenuation. I don't know at this point if the issue is in the K3 IF output or the AFEDRI input. The AFEDRI has adjustable RF gain and I can still see the signals if I crank the RF gain to the max but I have lost on the order of 20 dB in the IF connection. (I normally run the AFEDRI with about 20 dB of gain but I have to crank it up to 40 dB now to see the signals from the K3). I've tried rebooting things and checked the first layer of things like the coax cable but I haven't found the cause of this big attenuation. I went into the K3 menu and toggled the KXV3 off and on but that didn't help either. Thought I would ask if anybody has experienced attenuation like this in the K3's IF output.

I built that amp this past spring and it works great. I made my own cabinet, but bought the board from him. The parts were obtained through various online retailers. It works great - I've used mine, driven by 5 watts from my K3, on CW, SSB, and FM.

As it turns out, for reasons that escape me, TX INH was set Hi in my K3, despite me never (knowingly) have set it, since I have no transceivers. Go into the Config menu and dial up TX INH and make sure it's "OFF". Wes N7WS On 11/1/2014 9:03 AM, Steve Lett wrote: > I just purchased the entire K line.

This is used to block the INHIBIT# and other signals that should not actually go to the KPA from the K3. Some signals are already cut in the cable, but there are some that actually might be of use. INHIBIT# is one of them, but is very rarely used. Also, make sure that the INHIB IN entry in the KPA?s menu is set to DISABLE. While you are at it, make sure all the cables go where they are supposed to go. When in STBY, the KPA will show power out and SWR when power is above 25 watts. If you are not seeing this then make sure that you have the K3 output going into the KPA?s input. AND, make sure that you have that antenna output selected on the K3. - Jack B, W6FB > On Nov 1, 2014, at 11:33 AM, Wes (N7WS) wrote: > > Curiously, I just yesterday fired up my new KPA500 (kit) and had a similar issue.

I had never heard a noise like this one. I couldn't think of anything new around the house- and having no close in neighbors I was stumped. Interestingly, the only NB that 100% eliminated it was my bedside TenTec RX-325. But I digress. I took my KX-3 with a 24" whip on the BNC connector. AM mode on 160M and headphones. After eliminating any sources on the upper foors, I narrowed the search to my shop/lab. . More checking and I found a brand new LiPO charger that came with my new LED flashlight. I had forgotten I had even plugged it in. When the whip got close, the sound was deafening. The moral is- don't forget what's new in the house and the KX-3 makes a wonderful noise source detection tool.

I cannot get any power through the KPA500. You need a cable to put the KPA500 in TX mode. Two ways to do that, either one works fine. 1) an Aux Cable between the K3 and KPA500. 2) An RCA to RCA cable running the K3 to the KPA500. The AUX cable provides the additional function of bandswitching signals. But the KPA500 can bandswitch by detecting the frequency of RF input -- all it takes is a dit or a tap on the mic. So I use the RCA cable. 73, Jim K9YC From n6kr at elecraft.com Sun Nov 2 00:53:30 2014 From: n6kr at elecraft.com (Wayne Burdick) Date: Sat, 1 Nov 2014 21:53:30 -0700 Subject: [Elecraft] KPA500 fault at H44KW (no pwr high SWR) In-Reply-To: <1414901766474-7594358.post@n2.nabble.com> References: <003301ce0f7b$a94d69e0$fbe83da0$@blueyonder.co.uk> <1414901766474-7594358.post@n2.nabble.com> Message-ID: Sure, as long as the pinouts are the same, and the voltage and current ratings meet your switching requirements. 73, Wayne N6KR On Nov 1, 2014, at 9:16 PM, wa9fvp wrote: > Here's a funny story.

On 2m, with just 2w, I'm able to drive my SSPA to a full KW out (see the Oct 2012 QST article on the amp, or on the w6PQL web site). I do notice an instability on 2m, and hope Elecraft will address this when time permits. You won't notice this on SSB or FM, but in CW the carrier frequency jumps around a few Hz in a random fashion. You can also hear this on the KX3 LO signal in another receiver nearby tuned to the same frequency; it's barely detectable at 6m, and not at all on 10m and below, but it does make 2m CW sound less than pure. For me it was a great buy, and a replacement for older and less capable radios...I especially appreciate the ability to net transverter local oscillator offsets, and many of the other features.

I guess this makes sense, if you consider the 2m module is using the "x4" output of the KX3's local oscillator, so that if you tune to 144MHz for example, the LO would be running at 48MHz, so that in the 2m module the 144Mhz signal would be mixed with a 4x48=192MHz signal. This would place the "USB" image at 192+144=336MHz, which is discarded, and then place the "LSB" image (192-144) at 48MHz, which is then downshifted to 0MHz by the 48MHz LO in the main receiver. Because the LSB image is the one that is used, the frequencies appear "reversed" when you look at then on the I/Q output. By swapping the I & Q signals, you can effectively "reverse" the frequencies a second time, and get a normal display on the waterfall.

Mine feels warm on the > bottom and shows about 32C when everything else in the shack is 24C to 26C. I have not turned mine over to see how warm it is with the front panel power switch off. Remember, it is normally left in the position of having the rear switch turned on. There is a power supply that may be heating your bottom hot spot, but I'll let the official word come from Wayne or someone else on that. I can't turn mine over to see, since it is hooked up to many cables. On the other hand, I've checked mine many times on the sides, front, and top to see if there are any warm spots. I use an IR thermometer, so it is extremely easy and fast. Mine is always room temp unless I'm "heating it up". I also have a thermometer in the exhaust fan "cage" to keep an eye on that temperature, and I monitor temp on the amp's digital readout at all times I'm using it. If there is any condition or location (other than the bottom) that I can measure for you, spell out the conditions and I'll do it. I use it daily.

Seems to work well, occasionally I'll find it different, not sure why. In SS CW, I noticed that my lower span boundary was often 5 KHz up from the normal value ... such as 14025. It seemed to happen more when I was using the N1MM Band Map and clicking on spots, which sends frequency change commands to the K3. This is not a big deal, I just sort of like the bottom of the band to be at the bottom of the P3 span, but I can't find any other reason to complain except that I'm a retired engineer ... you know how we are, just ask my wife. This P3 effect doesn't seem to happen any other time, but it was pretty regular when the laptop was sending frequency commands to the K3.

In FLDigi there's a configuration knob to let you deal with that, under Configure->Misc->Sweet Spot. This will make the waterfall move in the correct direction when you tune, and it will make the QSY button tune your radio correctly. Please see if this fixes your problem in FLDigi. I don't know MixW, but it it changes direction from a certain band up, it may be configured to invert the sidebands like some old radios used to do. Other thing to make sure is that FLDigi (and possibly MixW) gets the mode correctly. Sometimes the K3 spews info too quickly and you get garbage in the Mode dropdown of FLDigi.

I?m replacing a Kenwood TS-480HX (an outstanding device also) which I ran with an Ameritron ALS-600S 600-watt linear. With some balancing and shielding I will be able to run the KX3 + KXPA100 into the 600 watt linear. So, I have my super compact QRP radio that I can put in my back pack and sit on a lawn chair with a Buddy Pole on top of a mountain, or the high power base station on my desk at home with the mini-beam. Cake and eat it too. The KXP3 pan adapter for the KX3 arrives today ? my weekend project. I?ll suggest the roofing filter especially for CW. Did not get an antenna tuner for either the KX3 or KXPA100, but might reconsider that later, since I have an auto-tuner for the big linear. Had no interest in using the KX3 on 2M and actually for the cost, you could probably find a very nice 2M rig. Assembly suggestion: they provide you with a lot of little teeny tiny screws. Get a cupcake pan or ice cube tray and separate all the parts and label them. Very difficult to tell a 5/32 screw from a 1/4. Tweezers help. And the customer support is extraordinary.

Simmons' wrote: > Does anyone put credit in the Sherwood Engineering Inc receiver findings? The reason I ask is in the past the K3 and then the KX3 was mentions as the testing show they were among the top receivers. Will now that the Flex radio 6700 is at the top now, does that say it is the best? Just wondering about what the test measurements revile versus the real would use of the radios. Hi Craig, Generally speaking, any of the radios near the top of the chart -- those having "Dynamic range narrow spaced" (2 kHz) in the high 90's or better -- will perform so well that you'd rarely notice the variation between them. You can then select based on other criteria, such as cost, size/weight, and features. If cost is your primary concern, I'm happy to say that you have two cost-effective choices in the top five from Elecraft. The other three radios in this group cost thousands more in their basic configurations. The Sherwood chart, by the way, is at: http://www.sherweng.com/table.html There's another of Sherwood's criteria which is notable and revealing: "100 kHz Blocking" (fifth column from the left in his table). Of the top 12 radios listed, only the K3 and the Hiberling hit the 140 dB threshold. What these two radios have in common is a down-conversion superhet receive architecture. Signals are first converted to a low intermediate frequency (8.2 MHz in the K3), where they are applied to one of several crystal filters. Downstream from these filters is an analog-to-digital converter, which drives the digital signal processor (DSP). The DSP does the work of demodulating signals and adding further amplification and signal processing, such as noise reduction. The advantage of the superhet architecture is that the A-to-D converter is protected from strong out-of-band signals by the crystal filters. This is of critical importance in multi-transmitter environments, such as big contesting stations, DXpeditions, Field Day, etc., as well as for home stations having high-gain antennas, or those that are in close proximity to huge interfering signals such as shortwave broadcast (or neighboring hams). Now back to your original question about the Flex 6700. It's certainly a heavyweight contender, and has some interesting characteristics such as the ability to look at multiple MHz of spectrum on its associated PC. (Of course it is a radio without a front panel, requiring the use of a PC keyboard and mouse for operation.) Two of the 6700's test results from Sherwood's table bear further scrutiny: 1. 100 kHz Blocking is shown as simply "A/D Limit" As I mentioned above, the K3 uses a superhet receiver with crystal filters that protect its A-to-D converter (ADC). This is not the case for the Flex, which has its ADC very close to the RF input of the receiver. The ADC is not protected by anything but very wide band-pass filters (multiple MHz), unless you turn on an attenuator. What this means is that the ADC becomes the limit on blocking dynamic range. ADCs do not handle overrange gracefully: as power builds up due to multiple signals appearing in the passband of the receiver, the ADC can start limiting, which generates a large number of spurious image responses ("ghost signals" that can be heard up and down the band). It is unclear just where this might start happening in the case of the 6700, since Rob did not publish any numbers. "A/D Limit" is a pretty ominous summary of what might be going on. I have heard that some testers will be evaluating front-end ADC limits using 3-tone testing, which can be very revealing. I'm looking forward to seeing those results. Meanwhile, I'm glad my K3 has crystal filters. 2. Noise floor with preamp off is only -118 dBm One of the nice features of the K3 is that even with the preamp off, the noise floor is -130 dBm (see Sherwood's chart). The Flex 6700 has a noise floor of -118 dBm with preamp off. What this means in practice is that on the higher bands, you'd be tempted to run with the preamp on at all times. There's also a footnote on the "Dynamic range narrow spaced" column that relates to the preamp. The 6700 is at the top of the chart only if its preamp is turned on (DR then = 108 dB). With its preamp off, DR is around 99 dB -- nearly identical to the K3 at 2 kHz, and worse than the K3 by 6 dB at 20 kHz. The reason the 6700's DR is better with the preamp on is probably because of the dramatic improvement in noise floor (from -118 to -135). But on the low bands where you run with preamp off, the DR will be 99, not 108 dB. On high bands with the preamp on, the ADC is subject to "A/D Limiting" 20 dB sooner. Time will tell what this means for operators. Regarding the KX3: The KX3 was optimized for small size and low current drain, and it's very low-cost relative to the other top-performning radios, so we were pleased to see that it performed so well in third-party testing. While it is not a superhet, it does have roofing filters as an option (in this case, analog filters based on precision op-amps). This is unusual for an SDR (software-defined radio). The K3 would be a better choice if you need excellent blocking performance close-in, again because of the crystal filters. But the KX3 is no slouch. Personally, I think it would be an excellent choice for a new General, but I may be biased :) 73, Wayne N6KR From rs500cat at icloud.com Tue Nov 4 10:26:28 2014 From: rs500cat at icloud.com (rs500) Date: Tue, 4 Nov 2014 07:26:28 -0800 (PST) Subject: [Elecraft] OK...

Here is something new to ponder about this that may help you... If I go to the "CW is LSB" option in MixW, and assert it, all behaves fine, (both waterfall and signal track as I turn main tuning dial), on 80, through 17 Meters, if on the other hand I then switch to any band 15 through 10 meters, I get the action where as I adjust the frequency up using the tuning dial on the K3, the "dial", (in the waterfall), on MixW, tracks fine, (as it does on the lower bands), but the signal moves in the opposite direction, so it looks as if the frequency of the signal is changing as observed by MixW. If I then uncheck the "CW is LSB" option, the actions are reversed-- that is to say, that all works as expected on 21 through 10, and the reverse behavior is on 80 through 17 Meters... This baffles me totally... If it happened with the change boundary at 14 Mhz, (20 Meters), I would say it is the rig changing sidebands... But it happens on 15 Meters, working just fine on 20... So my first thought was that it was just the radio changing sidebands, so I set the MixW as "CW is LSB", all works on 80-17, I go to 15, see the reverse behavior. I then then hold down ALT for changing to the opposite sideband... The change happens, but the reverse and lack of tracking behavior continues, just on the other side of the waterfall. There are some very odd things about the K3 I still don't understand... If I load up FLDigi, I get the reversed behavior on all bands... Maybe the K3s are possessed, this baffles me totally... At the risk of sounding frustrated, this did not happen on the Pro III, or PRO II I had... The serial port was also able to keep up, where I suspect the K3 is processor bound and can't keep up with a 38K data stream. Maybe you are right, somehow this is serial related, but I can't see how... I do have two ongoing serial issues: 1. During frequency load I get timeouts, I would not expect this. 2. The K3 appears to be unable to keep up with the data being sent by MixW, where the Pro series was able to do both items 1 and 2 with no issues. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Tue, 2014-11-04 at 07:26 -0800, rs500 wrote: > Dave, you are not alone.

Of course I should have looked at the International frequency allocations before asking about the 4 meter transverter. Duh... I appreciate all the input. You confirmed most of my thoughts about what to put into the complete KX3 station and what to leave out. As expected, the experts on the list came through big time. Of course since posting my question I've exchanged a few e-mails with my colleague, W1ZR, and he has me thinking about a more basic K3, and adding some of my wish list add-ons later. There are obvious reasons for both choices, so I am evaluating with option works best for me. Decisions, decisions. 73, Larry Wolfgang, WR1B From byron at n6nul.org Tue Nov 4 17:54:44 2014 From: byron at n6nul.org (Byron Servies) Date: Tue, 4 Nov 2014 14:54:44 -0800 Subject: [Elecraft] K2 cable distribution box instead of daisy chain? Message-ID: Hi, I am dreading having to re-build my K2 daisy chained cables as I re-configure my shack and add some new equipment. Soldering multiple wires into a DB9 connector has never been easy for me even thought I've been doing it since the 80's. So, I was thinking about building a little box that everything would plug into; a sort of K2 star network. Each K2 or accessory would have a straight cable that plugs into the box and there would be just enough circuitry to distribute the signals to the right connector. So, the daisy-chaining would be handled internally instead of at each DB9 connector. Has anyone done this? Good idea? Bad idea?

Message-ID: <201411042324.sA4NOaVI065108@huffman.acsalaska.net> Actually the KX3 is a good fit for any ham. With 10m, 6m, and 2m is great for the new Tech. And for the Extra that maybe is returning to ham radio after a busy life/career and now able to have a little more time for ham radio. Its a super nice radio considering size and cost since specs put in competition with radio costing much more. fantastic for portable and mobile or even the traveling professional that hasn't decided to slow down ;-) I got mine primarily to use on 2m as IF for microwave operation out on a hill-top "going lite". But, it has not gone out of the shack, yet ... gets duty monitoring for those rare 6m openings while my K3 is doing regular stuff. And it is a super QRP and packable radio for those endeavors. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From zl4pw at orcon.net.nz Tue Nov 4 18:45:15 2014 From: zl4pw at orcon.net.nz (Paul Ormandy) Date: Tue, 04 Nov 2014 23:45:15 +0000 Subject: [Elecraft] KPA5 Message-ID: <5459650B.4090806@orcon.net.nz> Hi all, Just calling FT4TA on 20m RTTY at about 500W, heard a loud crack from the KPA500, now not amplifying.

In-Reply-To: References: Message-ID: <54596B21.6050702@embarqmail.com> Byron, The K2 cable is in 2 parts. The TXD, RXD, Signal Ground (pins 2, 3, and 5) go only between the K2 and the PC serial port. All the rest of the wires are for control of Elecraft external devices - KAT100, KRC2, and the XV transverter series. It may work OK to arrange these second signals in a 'Star" configuration from a common "hub", but I do not know for certain because I have not tried it. I would suggest that you run the K2 to PC cable and the K2 to "other devices" in the same DB-9 connector that plugs into the K2 - then run the "other devices" end of that cable to your junction box. Then from the junction box, you should be able to parallel all the cables to whatever mix of "other devices" that you may have. The critical factor is the timing on the AUXBUS signal line. All the other signal lines are either DC levels or are at such a low rate that timing is not important. If you keep the lengths to the "other devices" short, I would believe you will find success. If it works, please share that information on the reflector. 73, Don W3FPR On 11/4/2014 5:54 PM, Byron Servies wrote: > Hi, > > I am dreading having to re-build my K2 daisy chained cables as I > re-configure my shack and add some new equipment.

I attended your talk at Pacifcon and have been implementing some bonding improvements including tying all the earth ground rods, tower etc. with #4 wire as well as better equipment grounding in the station. The beads on the power cable (only 110v AC no DC) appear to have improved the situation, but I understand it would be better to use multiple turns though a ferrite core on the VGA cable. Without clipping and re-wiring the end connector I have not acquired a big enough ferrite core to do the job. The BenQ does not appear to generate any trash at least to the level I notice it in my operations. At Pacificon, you did suggest a way to connect the monitor's DB-15 connector to the station ground through the small screws that hold the cable connector in place. I might try that.

Take off all of the clamp-ons and get things set up to reliably cause RFI. Then put 4 or 5 clamp-ons on one cable at a time. Try this on every cable in and out of your equipment. Such as the DC cable from your power supply to the K3. Then move onto the various PC cables. One of those cables is bound to show a reduction in RFI. When that happens just keep loading on the ferrites. For serious RFI one or two ferrites on a cable is never enough. 73, Mike K2MK mike wrote > When using KPA500 my external monitor (and the P3 display) often freezes, > sometimes up to 5 seconds, after I transmit.

Operate the K2 into a dummy load and monitor the data transmissions with a local receiver - borrow one if you have to, and you may need a 2nd computer for that test. You can feed the headphone output of the monitor receiver directly into the soundcard or even place a soundcard microphone near the receiver speaker to observe the decoded signal from the K2. Make certain the compression setting is 1-1 and adjust your SignaLink output to the level just below that which produces ALC bars in the bargraph - increase the gain until you see an ALC bar, then back down until it just goes off. If you operate SSB with compression it would be wise to activate the RTTY filter set and set the filters and BFOs for best operation with data modes. Remember that you must set the RTTY FL1 filter to OP1. You can copy the FL1 BFO settings from the SSB BFO settings. Using the RTTY filter set allows you to set the compression for the RTTY mode independently from the SSB compression setting. OK, if operating into a dummy load does not cause the problem, then you can blame it on RF in the shack. Rather than trying to fix the problem with ferrites on every cable, you may find easier and better success with using a more effective common mode choke at the antenna feedpoint and perhaps another common mode choke at the point where the feedline enters the shack. See the fine information on RFI by Jim Brown K9YC for creating effective common mode chokes. If you can keep the RF energy out in the antenna field where it belongs, you may not need any ferrite on the cables in the shack. 73, Don W3FPR On 11/5/2014 4:35 PM, Don Latham wrote: > My K2 with 100 watt amp and KAT100 works very well on ssb.

Jim Brown K9YC in his RFI tutorial shows the use of quite effective common mode chokes. 4 or 5 type 31 stacked ferrite toroid cores with 5 or 6 turns of coax wound through the stack. Use of one of those at the antenna feedpoint, and another where the feedline enters the shack will kill most all of the RF being brought into the shack on the outside of the coax shield. If you can keep that RF out of the shack by attacking it at its source and keeping it in the antenna field where it properly belongs, you may have little or no need for additional ferrite RFI suppression inside the shack. If you do need to use ferrite clamp-on cores on your in-shack cables, use ones with a large enough center that you can wind several turns through the core rather than adding more ferrite cores along the length of the cable - it is much more effective - you are building an inductor to choke off the common mode currents. 73, Don W3FPR On 11/5/2014 5:33 PM, Mike K2MK wrote: > Hi Mike, > > I think multiple ferrites will help but you might be surprised to find that > it works best when applied to a cable you haven't yet tried.

Set the power to 2 watts and adjust the 10 meter inductors for maximum output (L12 and L13) using TUNE, then switch to 12 meters and adjust C44 and C46 for maximum output. That should produce the best setting for both transmit and receive. If connecting the antenna when tuned to those bands results in an increase in noise in the receiver, you have all the sensitivity you can use. You should be using real signals (but weak ones) to compare receiver sensitivity - if you are comparing on the basis of the 'loudness' of the noise heard, that can create a false impression. What is important is the signal that stands above the atmospheric noise. 73, Don W3FPR On 11/5/2014 4:41 PM, Hans J Rasmusen OZ7BQ wrote: > My K2 (ser 04069) appears to lack a bit of receiver sensitivity on 12 and 10 Meters.

Right now I have the vga cable with two loops through a large snap-on of unknown mix (I have just ordered a couple of large 31 mix snap-ons) and placed seven snap-on beads of unknown mix on the AC cable. It looks like the situation is better as it now requires about a five second keydown to freeze the monitor, (not something that happens a lot, just a test.) I tried swapping the small beads on the AC line with a double loop through a snap-on (like the one I now have on the vga cable) but that was much worse. Regarding keeping RF out of the shack, Don, the 40/80 meter inverted vee has a several looped coax choke at the center feedpoint and the SteppIr vertical has a large DX Engineering one-to-one balun/choke. The Mosley 2 element Yagi has a common mode choke made of a string of beads originally used for a Spyderbeam. The coax feedlines are all between 75 and 100 feet. I will look into more suppression at the shack entrance. And Bryon, I will check to see if the BenQ mounting holes (I am using mounts) are connected to the D-shell.

In this way you are not limited to the PF1 and PF2 buttons. I use M2 through M4 to send SPLIT and SUB RX commands to the K3. And of course if you have a PC logging program running you should be able to set up macros from your PC keyboard. I have two macros that I use on my PC keyboard while running WriteLog that cause actions to occur on both my K3 and P3. One macro uses the F12 button and the other macro uses the * button on the numeric keypad. 73, Mike K2MK *********************************************** [Elecraft] [K3] Programmable/assignable Split Key?

Currently, my K3 and AL-811 sit on my desk. The Dentron sits about 15' away on top of a bookshelf next to the basement window where my antenna enters the shack (one wire for the radiator and one wire to the radial field). The Dentron has a "random wire" and "ground" post on the rear, which makes tuning this antenna a breeze (but I have to get out of my chair and re-tune whenever I switch bands). I'm considering the KAT500, but wonder how it would work for this situation. Here are my two (please suggest more) solutions: 1. Put the KAT500 right next to the K3 and AL-811 on my desk, run a 15' long 50 ohm line to a balun which would attach to the antenna outside my basement window. Computer control is easy because the KAT500 and K3 are right next to each other. 2. Put the KAT500 right next to the antenna and run a short (2-3') 50 ohm line to a balun which would attach to the antenna outside my basement window. A 15' line from the amp to the tuner would be required and no computer control would be possible. If I go with Option 1, then I am trying to match the 50 ohm line for 15' before I get to the balun/antenna outside the window. If I do with Option 2, then I won't be able to use the K3/KAT500 AUXBUS features (I had emailed Elecraft support about this in the past and they suggested not using a 15' long AUXBUS connector). Anyone else tuning random wires with the KAT500? How do you do it? Should I be considering another tuner altogether? I don't want to break the bank, but I do want a workable solution. 73 -john W4PAH Madison, WI From radiokc8i at icloud.com Thu Nov 6 12:27:18 2014 From: radiokc8i at icloud.com (Lyn Haddock) Date: Thu, 06 Nov 2014 10:27:18 -0700 Subject: [Elecraft] KXUSB with Linux Message-ID: <4EDF2E35-FC96-4B27-BA6F-54A89E18AC9F@icloud.com> I?m trying to connect my KX3/PX3 rig to a Linux computer to use the Utility programs.

If so, maybe it is kicking in too early, and you may need to look at setting the threshold (I think there are procedures in the K2 manual for this). You said peaking the band pass filter didn't help much (I guess you did this in the right order, as described in the manual?) What about the IF filter L34 adjustment? That could affect overall gain. Although not really related to sensitivity, while you are running alignment procedures, may as well go the whole way and check the setup of the crystal filter with spectrogram. It may be interesting to measure the sensitivity to see if there may be a problem. The following webpage may be a useful reference: http://www.cliftonlaboratories.com/k2_rx_sensitivity.htm When I built my K2, I used the measurement procedure in the XG3 signal generator manual to measure the sensitivity as a sanity check to see if I'd built it properly. The result came out somewhere in the ballpark of the figure published in Rob Sherwood's receiver performance list. http://www.sherweng.com/table.html There is an application note on the Elecraft website dealing with increasing the K2 sensitivity, although as the article mentions, there are trade offs: http://www.elecraft.com/Apps/RX_Gain_application_note.htm 73, Matt VK2RQ > On 7 Nov 2014, at 12:27 am, Hans J Rasmusen OZ7BQ wrote: > > Dear Don and Matt,Thank you for your comments.

Most likely the name of the port is /dev/ttyUSB0 as that has been standard convention for some time. Case matters in file names. If you are typing the name correctly, then all I can think of is that your username may not be a member of the 'dialout' group. You can easily check this in a terminal by typing the 'groups' command. There are various ways to do add your username to the 'dialout' group, as I recall, both Mint and Ubunutu offer a graphical program to manage your user's group membership. > When i unplug the KXUSB from the USB port on either Linux box and plug > it into my Mac, all is well.

I don't know about OS/X, but I recall that Windows will automatically make the device available to a non-privileged user. The Linux distributions are a bit more careful about security in this regard which sometimes seems like a bit of undue paranoia. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds.

There is a pot at R1 for the AGC Threshold level on all K2s SN 3000 and above. You can adjust the AGC Threshold lower than the suggested 3.8 volts, but as you lower it, the values for CAL S LO and CAL S HI become more and more erratic. I suggest keeping the voltage at CB U2 pin 5 to 6.5 volts or higher - a minimum of 2.7 volts is normally sufficient. 73, Don W3FPR On 11/6/2014 12:31 PM, Matt VK2RQ wrote: > > There is an application note on the Elecraft website dealing with increasing the K2 sensitivity, although as the article mentions, there are trade offs: > http://www.elecraft.com/Apps/RX_Gain_application_note.htm > > 73, > Matt VK2RQ > From w3fpr at embarqmail.com Thu Nov 6 14:25:36 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 06 Nov 2014 14:25:36 -0500 Subject: [Elecraft] Sub Band Speakers on 15M Band In-Reply-To: <001501cff9de$c806ab90$581402b0$@com> References: <001501cff9de$c806ab90$581402b0$@com> Message-ID: <545BCB30.6020202@embarqmail.com> Irwin, Do you have the Main tuned to 20 meters and the SubRX tuned to 15 meters? If so, the 20 meter Low Pass Filter is selected and will cut the 15 meter signal to almost nothing. The same thing can happen on other band combinations. To avoid that problem, either set the SubRX to a band lower than the MainRX. Or, use the AUX antenna input for the SubRX (that avoids the LPF). 73, Don W3FPR On 11/6/2014 11:29 AM, KD3TB wrote: > With the K3 in Split mode and Sub turned on, on 20 Meters I can hear the > Main and sub band in separate headset speakers, but cannot on 15 Meters > > > > Is there a Config/Menu function that has to be set by band? > From w3fpr at embarqmail.com Thu Nov 6 14:32:07 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 06 Nov 2014 14:32:07 -0500 Subject: [Elecraft] [K3] autotuner for K3 with AL-811 amp (KAT500 or other) / random wire antenna In-Reply-To: References: Message-ID: <545BCCB7.5050400@embarqmail.com> John, Use the 15' coax, but make sure it is low loss RG-8 size coax and all should be well.

Here is a list of the required Linux libraries and facilities that must be present and enabled for Elecraft Utilities to operate successfully on that platform. 1) 32 bit vs 64 bit Distributions The Elecraft Utilities for Linux are 32-bit and will not run on 64-bit distros. There are 32-bit compatibility libraries are available that will allow 32-bit apps to run. To install the 32-bit compatibility libraries from a terminal: sudo apt-get install ia32-libs 2) FTP must be installed on your Linux You will have to install cURL if it is not pre-installed. Most distros have it pre-installed, but not all. It is easy to install from a terminal: sudo apt-get install curl 3) Ensure our DialOut groups are set up properly Most users, other than root and members of the dialout group, do not have read/write permissions on the serial port device files. The Utilities cannot access the serial ports if the user does not have r/w permissions. An easy way to set the permissions is to add the user to the dialout group: sudo adduser << your username>> dialout Cheers, David -- --------------------------------------- David Shoaf/KG6IRW Elecraft International Distributor and Customer Support 831-763-4211 x121 --------------------------------------- -- View this message in context: http://elecraft.365791.n2.nabble.com/KXUSB-with-Linux-tp7594439p7594446.html Sent from the Elecraft mailing list archive at Nabble.com.

My K2 (S/N 3500+ with latest firmware updates) had been off, no 12vdc to rig for about 2 months. When I applied DC to the rig and ATU and tried running the auto-tuner I got PA HOT error on the display, this after about 1 minute of warm up! So, went to the KPA100 manual to check tPA calibration, I discovered it was set two 255 celius, a bit warm for my shack....LOL. Using the Fahrenheit to Celsius formula in the manual, tPA should have read 18 Celsius. So, I adjusted the KPA100 to room temperature and KPA100 has been working FB now. So, any suggestions why tPA would lose its calibration? By-the-way, CAL CUR is set to 3.5 amps per the manaul.

The setting for C22 is only used during a run of CAL PLL and CAL FIL when the frequencies (actually equivalent DAC values) are stored in EEPROM. Once that has been accomplished, the 4 MHz reference oscillator serves only as the clock for the MCU and for that function, the exact frequency is not important. If you want to do a calibration run on your K2, I suggest you review the K2 Dial Calibration article on my website www.w3fpr.com. 73, Don W3FPR On 11/6/2014 3:50 PM, Steve Kavanagh wrote: > I just acquired a second hand K2 (my second one) and upon going thru the operation in detail I noticed that it was somewhat off frequency.

I took a quick look at Ubuntu 14.04 and didn?t find GUI options like Mint has to work with user groups. I suspect I would need to edit a file, perhaps having to do with ?dialout? privileges. This is beyond my attention span since Mint is now working fine. By the way, the Linux Elecraft Utilities (at least the ones I tried) are 32 bit applications. I installed 64 bit Mint 17 and could not get the Utilities to open at all until I installed the 32 bit libraries for Mint. I used the commands suggested by David - W4DES, shown at the bottom of this link? http://elecraft.365791.n2.nabble.com/linux-K3-utility-td7589395.html This installation went fine and then the Utilities would open. There is a 32 bit version of Mint 17 available for download, and I suspect it would work as installed. Thanks again for the helpful replies. 73 and Have Fun!

Indeed you need to add yourself to the dialout group and have the 32bit libraries. It is an item that should be the system settings window under user accounts but as I wrote before in the reflector: I had the same issue in Ubuntu Linux. The reason was that by default only root has access to /dev/ttyUSB0. If you add yourself to the group "dialout" like this: In a terminal do at the ~$ prompt: sudo usermod -a -G dialout where should be your name as shown on the prompt before the $... type your password... log out then log in again and start the utility. By then it should work ok. At least to me it did....:-) Canonical seems not to like people to mess around with group policies therefore leaves out a gui application to set them. -As far as I know group policy settings are back again in Ubuntu 14.04 but as that has other less likable bugs I still use 12.04 and Gnome-session-fallback (yes: I don't like Unity) 73, Peter - PA0PJE Op 2014-11-07 19:15 schreef Lyn Haddock: > Thanks to some helpful hints from several in the group, I found the solution to getting Linux (Mint 17 Qiana, Mate Edition) to work with the KXUSB adapter.

I was having problems like this until I spoke with Elecraft, and they had me keep the PX3 off until I kicked on the KX3, which then successfully powered on the KXPA100, at which point I power up the PX3 and everything works as intended. Something about passing through the control signals. I forget what firmware revisions I was on, I've made it a habit now so no idea if that's still the process.

Make certain the leads are well stripped and tinned (you should see some tinned wire above the board) and RFC3 is wound on the right core - I have found a few where the builder used the black powdered iron core instead of the ferrite core. The winding of T2 can reduce the power on higher bands, but not as severe as you have, but check anyway to be sure T2 is wound as indicated in the manual and spaced 1/16 to 1/8 inch above the board. You will likely have to do some modified transmit troubleshooting using the test points indicated in the manual, but at a higher power setting than 5 watts (I would recommend 10 watts setting). At each test point, compare the RF voltage for 20 meters with that for 15 meters. When you find the place where the RF voltage for 15 meters is substantially less than that for 20 meters, you have identified the output of the failing stage. 73, Don W3FPR On 11/8/2014 10:42 AM, Steve Kavanagh wrote: > As I proceed with checking the new-to-me (S/N 5133, bare-bones, no options) K2 out, I'm finding that the maximum transmit power output drops markedly as the frequency goes up.

S-meter indication was low (about S9 compared to 9+&( on my IC-910H without amplifier. I put Preamp in service but may be I could put some extra gain in the RX chain. KX3 is "leaking a bit" as I could hear it on my IC-910H; useful in order to put both transceiver on the same frequency ;-) Tomorrow I will leave my vacation house in SW of France and move to Paris for a few months there so I need to stop my tests on KX3 + 2m for the moment. May be I will use it in Paris with a more decent antenna that whip I used first (in fact I would need a ground plane attached to KX3).

DATA MODE A normally uses USB for all bands (see the Elecraft manual on "Data Mode Selection", page 31 in may manual. It's easy to end up with a different Data Mode and then things vary band to band. When you activate the Data Mode button, it shows USB or LSB. If you change data mode, or the sideband selection, I believe those are saved on a per band basis, so when come back to a band, you get the last selection. You might have to go through and correct it on all the bands individually. Ken WA8JXM On Nov 4, 2014, at 10:26 AM, rs500 wrote: > Dave, you are not alone. I have observed the same issue on my K3.

If the signals you hear go UP in pitch as you tune UP the band, it is using LSB. If the pitch of the signals goes DOWN as you tune UP the band, the radio is using USB. Once you understand whether the radio is set to use LSB or USB for a particular band, you can then set your digital mode software to match.

DATA MODE A normally uses USB for all bands (see the Elecraft manual on "Data Mode Selection", page 31 in may manual. It's easy to end up with a different Data Mode and then things vary band to band. When you activate the Data Mode button, it shows USB or LSB. If you change data mode, or the sideband selection, I believe those are saved on a per band basis, so when come back to a band, you get the last selection.

RFC3 looks to be right. T2 was sitting right on the board but I was able to pry the side next to T3 up so that it is certainly clear of all the leads around it and there was no change. So I guess I will have to wait a day or two until I get home and have a go with an RF probe. I did do a few DC measurements and noticed that the emitter voltage of the driver, Q6, is about 0.25 V rather than the 0.4 V specified in the manual (at 0.1 W power setting...the manual doesn't clearly specify the power setting for the DC checks). I wondered if the beta of Q6 might be a bit weak...but it doesn't quite feel like what would drop the power by 10 dB. The bias is about right...around 1.05V.

My KAT3 mistuning symptoms were similar to those you describe, except it was worse on the LF bands, improving and almost normal on higher HF bands. My main wattmeter and swr functions appeared to be working, so the usual suspects (swr bridge diodes D36, D37) did not seem to be the cause. I would say that those diodes and associated components, and L10 C10 on the KAT3 are the first things to check. I was given very comprehensive (and as it turned out, good advice) from Gary Surrency over what to look for (summarised below), but it did not fix the fault initially in my case (perhaps because of multiple causes), I was chasing around for ages. 1. To replace the swr bridge diodes D36, D37 (I used 1N5711 but the swr bridge worked just the same so refitted the original smd diodes) 2. To re-fix all earthing screws and connectors around the LPA (3 screws underneath), KAT3 and the SO-259 antenna sockets. 3. To check for dry joints or touching wires on the LPA HFP filters and KAT3. 4. To check filter L10 C10 on the KAT3 (8.215MHz IF trap, can be temporarily shorted, only a parallel tuned circuit) 5. To check relay function if a specific band or bands (which does not appear to be your fault) 5. After these checks and changes every time do a re-calibration (Wattmeter and TX gain) I did all this (but without re-cal every time), found no definite fault even though it improved slightly, without a complete cure. It was still hunting. At this stage I was thinking of sending the motherboard back to UK or USA but reluctant to do this because of the trouble involved and I wanted to fix it myself! On checking further I looked at the swr toroids and found one (T3) where the centre insulation was missing partly and the copper wire may have been touching the ferrite ? if so this could have caused an intermittent. I replaced the small ?U? wire with another using PTFE insulation. Also I found correspondence relating to KAT3 earthing. (thanks to GM3SEK, W3FPR, G3TJP and others). The KAT3 is earthed via a screw holding its pcb to a hex pillar and 2D fastener to the side panel connected to the back panel, what appears to be rather an indirect route. If any of these dis-similar metal fixings go high resistance, or there is higher than normal RF induced in the K3, then this may cause a problem. I fitted an extra 1mm flex wire on tags between the bottom SO-259 bolt and the back of the KAT3 pcb. I cut the side of the tag behind the KAT3 pcb to avoid a track which ran close, and used a new nickel plated screw with very small flat washer to fix the pcb. Surfaces cleaned and with thin layer of professional contact lubricant. After re-calibration again the fault had gone! Unfortunately because of its intermittent and non-precise nature, it was difficult to pinpoint the exact cause. Possibly general deterioration via several factors listed above ? Am sure Elecraft support or others can either correct any errors above or suggest other things to try in your case. 73 gl John G3PQA (K3 s/n 1123) From: ZL3IO [via Elecraft] Sent: Friday, November 07, 2014 3:47 AM To: John G3PQA Subject: Re: KAT3 Mistuning Hi John I have a similar problem on all bands.

The emitter should be 0.6 volts *lower* than the base - which should put it at the manual's voltage of 0.4 volts. The power setting should not matter for that measurement. Check the emitter resistor on U6 - it should be 1.5 ohms. If this is a K2 below SN3000 without the A to B upgrades, R50 may be a 1/4 watt resistor, and it was replaced with a 1/2 watt resistor. If R50 has been overheated, it is conceivable that its resistance is lower than the 1.5 ohms. Another thing to check is the TX buffer stage U9. First measure the DC voltage at pin 3 - if Q20 is working properly, it will be at 12 volts (or power supply voltage) during receive, but drop to 1/2 that value during transmit (or TUNE). If it does not change, replace Q20 (2N7000 which is static sensitive). Also check the resistance of R93 (820 ohms) and R94 (82 ohms) as well as the value of C150 (330pF). Note that R94 and C150 are in series which makes the gain of U9 greater as the frequency is increased. 73, Don W3FPR On 11/9/2014 10:56 AM, Steve Kavanagh wrote: > Don: > > Many thanks for the tips!

In doing some experimentation with a bandpass flter in the loop between the RX antenna "out" and "in" on the KXV3A I have discovered something which has baffled me. I have a 2KW station on 1480 kc 1.5 miles north of me and a 20KW station on 1300 kc about 5 miles south of me. The 1300 station is directional north and I am right in the boresight. I am experiencing +30 to +40 dB over S9 intermod from these two stations on 1840 kc. An intermod calculator shows a 5th order intermod at 1840 from the two stations. I normally run QRP at 5W cw and what I have discovered is that when I crank up the power above 15W (activating the KPA3), the intermod drops to about +5 to +10 dB over S9. This behavior is very consistent when switching between low and high power. Can anyone explain this or is something broke in my K3?

The insert point is *after* the PIN diode T/R switches for both the HPA (KPA3) and 10W LPA. Given Vic's description, it is likely the noise is being generated in one or more of the PIN diodes in the T/R switching and placing the highpass filter in the insert point will not resolve the noise. Vic, you can bypass (disable) the KPA3 to see if the noise generation is in the KPA3 T/R switch. 73, ...

It must be between the T/R switch and the antenna, which means it has to be able to handle transmitter power. There is a T/R switch in the KPA100 and one in the driver stage (which is the final in the QRP K3). Possibly the two T/R switches behave differently.

With the P3 on, hold down the MENU and PWR keys. Note, this will reset any function keys you may have set up. The frame rate will slow when the span is very narrow. For example at 2 KHz span, the frame rate will slow substantially due to increased sampling.

Sure, heatsink compound, carelessly applied, can be messy but given there is an oft reported issue with heat and the K144XV it seems, unless there are thermal pads somewhere hidden in the procedure, compound between the aluminium slab wall of the K144XV and the K3 side panel might be a something worth trying.

One simplistic way is to not use PTT - either use VOX or let the computer PSK31 application set the KX3 into transmit (some programs do it, others do not without additional aiding applications - example: flrig or hamlib or rigcat used with FLDIGI). The only way to "wire the plug to activate the PTT line on transmit" is to build your own cable. And you would have to use a serial port output on the computer and a 'one transistor keying interface' to control the KX3 PTT input line. It is easier to either use VOX or set the software application to key the transmitter by a CAT command. You will need 3 connections between the computer (or interface box) to the KX3 -- KX3 headphone output to the line-in (or mic in) on the computer -- Computer headphone output to the KX3 microphone input. -- The KUSB cable from a computer USB port to the KX3 ACC1 jack for software control of the KX3. You may find the KX3-PCKT Cable Set would be a helpful addition. It does contain a PTT input in the cable to the ACC2 jack, but requires setting the ACC IO menu parameter to the correct setting for your application. If you find hum or data corruption problems exist, they can be addressed with the methods in K9YC's RFI Tutorial for bonding your gear together, or use audio transformers to isolate the KX3 audio from the computer soundcard. I hope I have helped with some of your choices. It is not really complex, but with the number of choices available (dictated primarily by the choice of the PSK software and its settings), I have had to touch on several of those choices, and you will have to select one and try it out. Some study of FLDIGI help files may be in order. It is really not 'computer geek' stuff, but there is a bit of a learning curve if you are just starting. Actually, I think it may be easier than connecting a GPS to the aviation navigation system. 73, Don W3FPR On 11/10/2014 4:11 PM, Michael Lozano wrote: > The KX3 Manual states: > > Connect your computer?s audio output (Headset Jack) to the MIC jack.

I'm not a contester, but have done similar with mine with no issue. The fan will scream at you as it gets above 70C, but the temp levels out. I'm not one to push much beyond that, as that's all the warmer it gets in JT exchanges running power.

Correct. Full linearity is needed for these modes to keep IMD under control.

I should add, I'll be glad to make test temp readings for anyone wanting them. I have a digital thermometer sensor in the fan grate to show outlet temperatures and I monitor the internal temp via the front panel readout any time I'm using it, even when on SSB, where the fan almost never runs. In addition, I have an IR thermometer and can spot check anywhere outside the temp (except bottom) for you if needed. Just contact me directly.

How did you measure the power difference and did you do so with an instrument with enough resolution to accurately measure that difference at the power level you were using? For example a Bird Wattmeter can't possibly measure with that level of accuracy nor is one likely to be able to read an analog meter that closely.

The specific Mark/Space power levels were measured by placing the rig into transmit in FSK_D mode with the FSK input closed (Mark), measuring the power output for a given power setting, then opening the FSK input and noting the PO (and change). In all cases, the difference between MARK and SPACE was less than 2% (less than the meter's specified accuracy) and at two power levels (55 and 80 W) the measured difference was less than 0.2W (<0.2 dB at 55W). These measurements were made with standard "High tones" (2125/2295 Hz) and the K3 was equipped with the optional 2.8 KHz, 8 pole IF filter. 73, ...

The DL1 is the most accurate RF power measuring device under $30 and competes with RF power meters costing much more. Couple it to an accurate DVM and you have a very decent power measuring setup. Of course it's absorptive and not in line like a Bird but hey, it's a start. If you put the scope probe across the 25 ? tap where the diode is connected and left the DL1 output open, you could get an accurate "sample" of the RF envelope across 25 ?.

Second, my measurements were taken with a watt meter capable of .01 W (10 mW) precision and the worst case difference was less than 2% (0.08 dB) - not the 10% claimed. Dynamic (scope) measurements may show a slightly greater dynamic difference - if you can read them with the precision necessary to detect a 3% ripple on a 140V RF envelope - due to wave shaping for bandwidth control. Even then, such minor (0.08 dB) differences in mark/space power are insignificant with the majority due to ripple in the IF filter. Both the 2.7 and 2.8 KHz filters show > 1dB ripple in the passband - see: http://www.elecraft.com/K3/K3_filter_plots.htm 73, ...

Filter passband ripple has the the stock answer to what people are observing. Also what about dynamic vs static differences. Is it possible in the dynamic situation the differences would be greater? It does sound like there is some confusion precision with accuracy. A measuring device might offer high precision and resolution but lower absolute accuracy. People often make accurate difference measurements with with a device which less accurate than the delta one observes. If the difference are small, they can be quite accurate. 73 de Brian/K3KO On 11/11/2014 02:13, Joe Subich, W4TV wrote: > > > My K3 increases power by 10% when in Space as opposed to Mark. > > Two things here ... 10% is abut 0.4 dB.

That's not the reason for using a better sound card. Indeed, NO transformers are needed if the equipment is properly bonded together. The reason for using a better sound card is for better A/D converters and a quieter signal chain, which results in MUCH better decoding of digital signals. > the advantage of the signallink is that it has real level pots and its > becomes a second sound card. The SignalLink has several serious problems, and is NOT a good solution. Further, it's a single channel box.

Recent measurements I've done of a K3 driving a KPA500 both with pink noise on USB and keyed CW show that not to be the case. Yes, bandwidth increases a few dB from 400W to 600W, but I would NOT call it serious. This is preliminary work and a preliminary report. At its current stage, it's a proof of concept.As I have time (and the radios to test), I plan to look at lot of others. I've just lined up a couple in the FT1000MP family.

There is no doubt that turning a pure FSK modulated signal into an FSK + AM modulated (QAM) signal increases bandwidth. The question is how much and how far down are the additional side bands. I'm sure there are guys here who can either calculate or measure the effect. It would be interesting to know the answer. As a practical matter, mother nature does this to almost all FSK signals via propagation effects. Often received mark and space amplitudes different by a LOT more than the amounts we're talking about here. It is interesting to watch this. Given this mother nature bandwidth smearing, it is doubtful that the real world impact of K3 QAM vs pure FSK is significant. 73 de Brian/K3KO On 11/11/2014 06:56, Phil Wheeler wrote: > As a practical matter "My K3 increases power by 10% when in Space as > opposed to Mark": is this really something to be concerned about? > > Phil W7OX > > On 11/10/14 10:51 PM, Brian wrote: >> And what if this was done this with the standard 2.7 KHz filter? >> Filter passband ripple has the the stock answer to what people are >> observing. >> >> Also what about dynamic vs static differences.

Huh? "Full linearity" would be zero distortion. ALL amplifiers have some amplitude distortion. See ARRL test results for a sample of current products. 2-tone IMD in the range of -30dB is pretty common. In the link I just posted, look at the occupied bandwidth of the K3 driving a KPA500 to full power, and to a few dB less power, then compare to the K3 driving a triode tube amp to legal limit. The IMD sidedbands are clearly visible, even with a CW signal -- remember that a CW signal is a carrier amplitude modulated by a square wave. The square wave has harmonic content (as a function of its rise time and shaping), so it produces IM. 73, Jim K9YC From jim at audiosystemsgroup.com Tue Nov 11 03:07:03 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 11 Nov 2014 00:07:03 -0800 Subject: [Elecraft] Signalink and K3 In-Reply-To: <54612780.2503ec0a.18a8.fffff48a@mx.google.com> References: <54612780.2503ec0a.18a8.fffff48a@mx.google.com> Message-ID: <5461C3A7.6040301@audiosystemsgroup.com> On Mon,11/10/2014 1:00 PM, Jorge Diez - CX6VM wrote: I am to buy a signalink and want to know which is the best way to connect it to the K3 so I can order the right cables Don't waste your money on it, Jorge.

Don't do this kind of mental exercise at 2AM. There is a big difference in the "bit rate" between QSB and RTTY. 1)Those engaged in Frequency Measurement Tests typically observe carrier frequency shifts <1 Hz over several minutes due to propagation effects. Most of this is due to Doppler effect of moving reflecting layers. Amplitude variations are due to multipath signal phase difference. Anyhow the effective "bit rate" is low. 2)FSK with 45 baud amplitude modulation, one would expect a series of sidebands. They would occur outside the usually occupied spectrum for a series of RY's (essentially a square wave)-- maybe +/- 200 Hz and up. It probably makes a significant difference in sideband amplitudes and placements, whether the FSK transition is phase continuous or not. The text content being sent affects amplitudes of the additional sidebands. Maybe these conclusions made at 3:45 AM are more accurate. Again it would be neat to compare the calculated bandwidths for the two point QAM scheme (F1,amplitude 1), (F2, amplitude 2) to the ideal FSK (F1, amplitude 1), F2 (amplitude 1) modulation schemes. 73 de Brian/K3KO On 11/11/2014 08:03, Brian wrote: > Phil, > > That's the right question.

In doing some experimentation with a bandpass flter in the loop between the RX antenna "out" and "in" on the KXV3A I have discovered something which has baffled me. I have a 2KW station on 1480 kc 1.5 miles north of me and a 20KW station on 1300 kc about 5 miles south of me. The 1300 station is directional north and I am right in the boresight. I am experiencing +30 to +40 dB over S9 intermod from these two stations on 1840 kc. An intermod calculator shows a 5th order intermod at 1840 from the two stations. I normally run QRP at 5W cw and what I have discovered is that when I crank up the power above 15W (activating the KPA3), the intermod drops to about +5 to +10 dB over S9. This behavior is very consistent when switching between low and high power. Can anyone explain this or is something broke in my K3?

The insert point is *after* the PIN diode T/R switches for both the HPA (KPA3) and 10W LPA. Given Vic's description, it is likely the noise is being generated in one or more of the PIN diodes in the T/R switching and placing the highpass filter in the insert point will not resolve the noise.

Sounds like you have some problem between the amplifier and the antenna. Yes, that's a broad area, but includes it all. I had similar problem for awhile and found various small things that lower power didn't show up. Clean up the system, get rid of bad jumpers, clean the connections, and try it again. But first, shove a dummy load on it and see that it runs full power with no problem. If it doesn't, make sure the load is plugged directly into the amp with a good jumper. Eliminate every connection one by one until you find it...and then keep looking all the way to the antenna to clean up the whole system.

This would tend to explain why Russ sees a more of a problem at low power than at high power. Current through the receive diodes in the KPA3 is about three times as much as those on the RF board (13/200 vs. 7/320). One would need to look carefully at the specifications of the PIN diodes and the FETs being used for switching. However, the resistors to "tweak" would be R58 on the mainboard and R25 (as Lexa mentions) on the KPA3. The idea would be to keep the diodes turned on hard enough to prevent them from turning off on RF peaks. 73, ...

The are easily replaceable, and we can send you as many as you need. I believe the price is quite low. I don't believe is is possible to clean them, as they are sealed. In contrast, the VFO A and B encoders are optical, not mechanical, and they are specified at 10 million rotations. But the cost difference between optical and mechanical is huge (about 40:1). The mechanical encoders are very small, fitting in the available space, and are a pragmatic choice for the function controls. 73, Wayne N6KR On Nov 11, 2014, at 8:57 AM, "Olli Tuppurainen" wrote: > Has anyone figured out how to clean or fix front panel encoders (SHIFT/LO , > HI /WIDTH) ?

Nothing specific about this antenna switch -- getting any matrix switch like that to have low SWR at 6M is quite tricky to do. I had a similar problem with a different 2x6 switch on 6M -- rather high SWR. My solution was to not run my SteppIR through that switch. Instead, I feed it directly into one output of my KAT500. The matrix switch feeds a different input of the KAT500. I also found that other "stuff" I had in series with the path between the KPA500 and the tuner was increasing to the SWR -- a not very good power/SWR meter and a tapoff for a monitor scope. I also found a few junk connectors connecting that stuff. Bottom line -- when I cleaned up the signal path, SWR went from slightly more than 2:1 down to 1.1:1. 73, Jim K9YC From pbruk at gmx.de Tue Nov 11 14:11:53 2014 From: pbruk at gmx.de (Pbru kr) Date: Tue, 11 Nov 2014 20:11:53 +0100 Subject: [Elecraft] K3 connect to SB220 Message-ID: From dmoes at nexicom.net Tue Nov 11 14:26:03 2014 From: dmoes at nexicom.net (dmoes at nexicom.net) Date: Tue, 11 Nov 2014 14:26:03 -0500 Subject: [Elecraft] Signalink and K3 Message-ID: <546262cb.2b75.5f09c940.411e433d@nexicom.net> Jim and Jorge I was merely answering Jorge's question. perhaps I should have given better advice and steered Jorge away from signal link as you did.

Looking at the schematic, the T/R switch for the LPA uses the MA4P which is a true high power pin diode, but the KPA3 actually uses the S1M which is a rectifier diode. It makes me wonder why different type were used in the two designs. I assume this is correct since my K3 is one of the early ones (S/N 732). I t looks like both can handle 1A forward current. So... it looks like my options are to take apart my old faithful K3 (again) and change the resistor R58 as you suggested, or try to fabricate a high power bandpass or high pass filter, or just ignore it and stay away from 1840. I guess I'll have to seriously consider the first option.

This would tend to explain why Russ sees a more of a problem at low power than at high power. Current through the receive diodes in the KPA3 is about three times as much as those on the RF board (13/200 vs. 7/320). One would need to look carefully at the specifications of the PIN diodes and the FETs being used for switching. However, the resistors to "tweak" would be R58 on the mainboard and R25 (as Lexa mentions) on the KPA3. The idea would be to keep the diodes turned on hard enough to prevent them from turning off on RF peaks. 73, ...

The Signalink is not required and is probably not up to par with just using a *good* soundcard. My first "soundcard" sw mode was psk-31 back when no body made interfaces, so I made my own (circa 1998). Obviously using the internal computer soundcard spkr and mic connections to connect to my FT-847 (which nicely provided an audio and PTT DATA port). My interface had 600-ohm 1:1 transformers and a NPN transistor for keying the radio from the DTR or RTS in the RS232 cable. http://www.kl7uw.com/Radio-Computer%20IF.jpg It was not long and several companies jumped into the soundcard interface business. On 2003 a new digital mode for eme was introduced (JT44) and I jumped on installing and running it. It morphed into JT65 in a couple years and about 3-4 years ago MAP65 emerged. I have run them all. http://www.kl7uw.com/MAP65.htm I was thrilled to find that Elecraft had the forethought to include the necessary interfaces for running soundcard digital modes without any extra "stuff". Now some other things I am involved in (I bought a LP-Pan) required better soundcard modems so I bought the (then) recommended emu-0202 external soundcard and later a four channel M-Audio Delta44. They run faster A/D and could support watching up to 190 KHz of spectrum with panadaptor sw (and WSJT sw). I think they also exhibit better linearity. Ahah! This is one of the characteristics that appear to help sw programs like JT65 "work better"! I have not studied recent soundcard offerings, but I am sure there some experts on that topic on this list who can assist anyone looking to *upgrade*. One thing to consider is OS compatibility (drivers). The other is physical interface (USB, RS232, etc.). My Delta44 has pci mounted pcb; you will be custom-building a computer to have a pci-buss these days). So *bottom line* the K3 does not need a Signalink. 73, Ed - KL7UW http://www.kl7uw.com/station%20layout.htm -------------- I ran JT65 EME for a long time using the computer sound card and had mysterious periods of no decodes even on signals I could easily see on the waterfall. This occurred even though I had carefully calibrated the clock rates. Then I bought a Tascam 122 mk II external sound card and the vast majority of missed decodes vanished. Plus you get two nice, big knobs to turn. Just make sure you install the latest firmware AND driver from the Tascam website--mine would not even work at all out of the box until I did this. Well worth the money, and as Jim says, you don't need the interface. 73 Eric WD6DBM 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From jim at audiosystemsgroup.com Tue Nov 11 16:07:27 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 11 Nov 2014 13:07:27 -0800 Subject: [Elecraft] KPA500 Power In Digital Modes In-Reply-To: <546228A2.6060307@subich.com> References: <545FE7EC.5000606@socal.rr.com> <545FE828.3000204@socal.rr.com> <5460F711.3020006@audiosystemsgroup.com> <54615889.6080507@subich.com> <5461B8A4.3060402@audiosystemsgroup.com> <546228A2.6060307@subich.com> Message-ID: <54627A8F.6010703@audiosystemsgroup.com> On Tue,11/11/2014 7:17 AM, Joe Subich, W4TV wrote: > Your measurements are not of the conditions I describe.

Right -- my test conditions for SSB are MORE demanding than either PSK31 or JT65A, and were intended to approximate the response of the K3 (and amp) to a speech signal. I also made one measurement of the K3 at high power without compression. Occupied bandwidth was nearly identical to the 10dB compression, so I did the rest with compression. Did you miss the CW measurements, where the modulation was a shaped square wave? When I have time (I'm currently hot and heavy with antenna work), I will, however, repeat these measurements with a PSK31 test signal, and with JT65A. I don't expect the results to be a lot different. 73, Jim K9YC From gm3sek at ifwtech.co.uk Tue Nov 11 16:27:45 2014 From: gm3sek at ifwtech.co.uk (Ian White) Date: Tue, 11 Nov 2014 21:27:45 -0000 Subject: [Elecraft] Signalink and K3 In-Reply-To: <201411112103.sABL3auQ049856@denali.acsalaska.net> References: <201411112103.sABL3auQ049856@denali.acsalaska.net> Message-ID: <007f01cffdf6$5b36bd90$11a438b0$@co.uk> On a related issue, has anyone located a Windows 7 driver for the EMU-0202? 73 from Ian GM3SEK From jim.w4atk at gmail.com Tue Nov 11 16:47:56 2014 From: jim.w4atk at gmail.com (Jim Rogers) Date: Tue, 11 Nov 2014 15:47:56 -0600 Subject: [Elecraft] KPA500 Power In Digital Modes In-Reply-To: <5461E539.3080702@mchsi.com> References: <545FE7EC.5000606@socal.rr.com> <545FE828.3000204@socal.rr.com> <5460F711.3020006@audiosystemsgroup.com> <5461E539.3080702@mchsi.com> Message-ID: <5462840C.1000501@gmail.com> Then you have a problem.

What are those problems? Probably the best place to start for issues with Signalink is: http://www.frenning.dk/OZ1PIF_HOMEPAGE/SignaLinkUSB-mods.html In general (at least in the case of the original units): 1) the Signalink design lacks a regulator for the V/2 bus that provides both a reference for the CODEC and the audio op-amps. The manufacturer of the CODEC (TI) calls for the V/2 regulator in the product data sheet and extensive audio design experience recommends regulation of the V/2 voltage in op amp circuits. 2) the Signalink is USB powered. However, the USB power is not adequately filtered or decoupled placing digital noise from the computer on the Signalink power bus (and coupling into both transmit and receive signals). 3) the Signalink uses low quality audio isolation transformers which create significant "tilt" across the passband 4) the Signalink internal PTT circuits require the CODEC output be run wide open for reliable PTT action. At lower voltages (and without regulation), the CODEC generates significant distortion at maximum output. 5) the Signalink internal power distribution lacks proper by-pass and decoupling resulting in both noise and audio crosstalk distribution via the power circuits. 6) In spite of the use of transformers, the unit still appears to be susceptible to a "pin 1 problem" and RF feedback - probably due to a number of the previous problems and most likely due to the lack of proper filtering/decoupling of the USB power source. > There's a fix in a recent QST (this summer) for one of them.

That SSB is *more* demanding than PSK31 is incorrect. SSB audio can be compressed/clipped significantly without IMD if the compression is done correctly. PSK31 on the other hand *can not* withstand *any* compression without significant close-in IMD. See the work by W7AY for that information. JT65A (and other JT modes) on the other hand is a saturated single tone mode akin to FSK that has *no issue* with compression and is, in fact, not compressible. > When I have time (I'm currently hot and heavy with antenna work), I > will, however, repeat these measurements with a PSK31 test signal, > and with JT65A. I don't expect the results to be a lot different. If you do the measurements correctly, they will be a LOT different. JT65A will show little or no change in IMD from 25 to 100 W average (and PEP) output on the K3 (or 100W to 600W average and PEP output on the KPA-500. PSK31, however, will go to pot in a hand basket if the average power output on the K3 goes above 30 watts or so or if the average power output of the KPA500 goes above 150 watts or so. If you are measuring *TRUE* peak power, those are equivalent to 100-110 W PEP from the K3 or 600W PEP on the KPA500 given the 6 dB crest ratio in the PSK31 waveform. JT65 and JT9 (all sub-modes) have a 0 dB crest factor, PSK31 has a 6 dB crest factor - other modern data modes have various crest factors - you need to understand the crest factor of the input waveform. > Did you miss the CW measurements, where the modulation was a shaped > square wave?

I see the Tascam mentioned in the PDF in the other thread, so I'm looking into those (the ones that support 192kHz now, that is) - are there any other suggestions to look into? I operate on a lot of digital modes, but my Lenovo Thinkpad T400's built in sound card adds a lot of noise to the signal I'm receiving. I have a Native Instruments Audio Kontrol 1 which works much better, but it is USB powered (it seemed to be indicated this was a no-no for best decoding in digital modes in the other thread). There are a lot of options out there now, so it's hard to sift through them all, and make a guess as to which are best for HF radio digital communication, so I thought a thread would be helpful in getting some ideas on what is tested/true. If Linux support is unknown, that's ok - I can do that research - but it would be great to have a list to start looking at that are known good performers with low noise. Thanks!

You will have to 'monkey' with the default soundcard for Windows each time you add one, because Windows always automatically sets the latest added card as the default. You select the soundcard to be used in the individual application. The 'problem' is "how do you get all applications to talk to the transceiver through one serial port" when each of those applications want to have a dedicated port to control the rig. Larry Phipps N8LP has created LP-Bridge which creates virtual ports that can be used to connect those other applications and send their command/responses through to the rig over the real serial port. There are other virtual port applications that do the same thing, but LP-Bridge was initially created for the K3 and works quite well with it - LP-Bridge presents an interface to the various applications that look like a K3 and buffers some information so as to reduce the polling and responses from the K3. There is an alternate LP-Bridge2 that works with other transceivers. Additional information can be had on the LP-Pan Yahoo Group. Larry is quite approachable and helpful with setup questions posted on that group reflector. Ed may chime in with more detail. 73, Don W3FPR On 11/11/2014 5:59 PM, Art Greenberg wrote: > On Tue, 11 Nov 2014, Edward R Cole wrote: > >> Now some other things I am involved in (I bought a LP-Pan) >> So *bottom line* the K3 does not need a Signalink. > > Ed, I presume you're running some I/Q processing with the LP-PAN.

Some soundcards do that better than others. One place to look for soundcards that have been tested by the manufacturer of LP-Pan is at his website www.telepostinc.com. Yes, all of Larry's info is Windows based, but the soundcard hardware info should be valid no matter what the OS may be.

Yes, the better soundcards have a lower noise floor which can help, but great bandwidth and bit rates are not required for those applications. OTOH, if you are looking at panadapter applications, a good soundcard is important to get 192 kHz span width with low noise, and you sill want to use it at the higher bit rates unless you are satisfied with a 96 kHz span. Select your needs and then select the soundcard that will fulfill those needs. Even the lowly 16 bit cards are adequate for data mode applications. 73, Don W3FPR On 11/11/2014 8:51 PM, dmoes at nexicom.net wrote: > > Im just curious > > I can see the bit depth making a difference 16 bit will have poor > dynamic range compared to 24 or 32 bit and this is important for some > modes like wspr or JTXX, but is there any advantage to high bit > rates in digital modes even a 44khz card has a bandwidth way beond > what any digital mode on HF needs. or is it that to get a 32bit > adapter just by default it will have high bit rates. > From w3fpr at embarqmail.com Tue Nov 11 21:23:57 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 11 Nov 2014 21:23:57 -0500 Subject: [Elecraft] Suggestions for good 192kHz external sound card fordigital modes In-Reply-To: References: <5462bd24.2b75.5ecdc940.3bba7446@nexicom.net> Message-ID: <5462C4BD.1030206@embarqmail.com> The limit in the KX3 I/Q outputs is due to the falloff of the output response of the KX3 - no soundcard can compensate for that.

Not necessarily -- the problem with the SignalLink is that it's done badly. Both of the units I recommend are USB powered. In the pdf, I described how I tested. If you run JT65 and regularly see decodes in the range of -20 and have no issues with hum, buzz, or RFI, your unit is probably fine. 73, Jim K9YC From n1al at sonic.net Tue Nov 11 23:14:45 2014 From: n1al at sonic.net (Alan) Date: Tue, 11 Nov 2014 20:14:45 -0800 Subject: [Elecraft] Suggestions for good 192kHz external sound card fordigital modes In-Reply-To: <5462C137.9040302@embarqmail.com> References: <5462bd24.2b75.5ecdc940.3bba7446@nexicom.net> <5462C137.9040302@embarqmail.com> Message-ID: <5462DEB5.6030402@sonic.net> I agree with Don. A high sample rate and large dynamic range are important for a panadapter but not for digital modes via the audio in/out of a transceiver. Even a 16-bit sound card theoretically has 96 dB dynamic range. True, it is probably not that good in practice, but it's hard to imagine the noise would be high enough to affect decoding the digital signal. For example, if the signal is S9 and the noise is S2, that's only (9-2) * 6 = 42 dB signal to noise ratio (assuming 6 dB per S-unit). Another factor is that 192 ksamples/sec sound cards need custom drivers that you have to install. The standard USB audio device driver that is built into Windows is only good to 48 ksamples/sec (stereo) as I recall.

I bought the emu-0202 to run with my LP-Pan since it was recommended (simple answer). Now to address your question. Yes, I needed to use a SDR (I chose the LP-Pan) to produce a IQ baseband output for the software I wanted to run (eg. MAP65). For this application I am not using the 15-KHz DSP of the K3 at all so not using the audio lines to the computer. The reason is that I needed faster A/D for wideband spectrum (90-KHz) display and the audio output of the K3 is limited to 4-KHz. I do use the RS232 I/F for keying the K3 Tx with the DTR line. However, I can run JT65 using the 4-KHz audio line-out from the K3. For that all that is needed is a soundcard. I use my emu-0202 because my internal soundcard "crapped out"; I disabled it so I could use the external soundcard. JT65 can display up to 4-KHz. I am not the person to answer running multiple simultaneous soundcard applications because it don't. But I suspect there is a way.

That info should be available in the archives if you do a search. If you have a Panadapter application loaded on your computer and a good quality wideband soundcard, you will be able to see the falloff on the display. When receiving no signals, but only band noise, the panadapter passband will take on an upside down "U" shape if your soundcard is capable of 192 kHz. That shape will indicate the actual falloff for your particular KX3. The PX3 does compensate for this loss of gain as the spectrum width is increased. Most of us do not have the capability to build special soundcard software, but if you do have that capability, perhaps you can make a KX3 panadapter application available to KX3 users which does the same "boost at the edges" as the PX3 does. 73, Don W3FPR On 11/11/2014 9:27 PM, David Orman wrote: > I am using it for wide-frequency viewing, which is why I made my request as > such re: 192kHz.

I don't know where you got the idea that I was suggesting compression for PSK31. My testing with pink noise is intended to simulate speech, and I tested with and without compression. It's raining, which stops antenna work, so I set up PSK31 measurements this afternoon. Here's a link to the data. Note that I used PSK-D mode -- internally generated by the K3. http://k9yc.com/P3SpectrumMeasurementsSlides.pdf Note that, except at full power, PSK31 is significantly narrower than CW. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Nov 12 01:40:16 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 11 Nov 2014 22:40:16 -0800 Subject: [Elecraft] Suggestions for good 192kHz external sound card fordigital modes In-Reply-To: <5462DEB5.6030402@sonic.net> References: <5462bd24.2b75.5ecdc940.3bba7446@nexicom.net> <5462C137.9040302@embarqmail.com> <5462DEB5.6030402@sonic.net> Message-ID: <546300D0.5040804@audiosystemsgroup.com> On Tue,11/11/2014 8:14 PM, Alan wrote: > Even a 16-bit sound card theoretically has 96 dB dynamic range. True, > it is probably not that good in practice, In the pro audio world, we think of a 16 bit card as being more like 90 dB, which is FAR more than we need as an audio interface for a radio. The 6dB difference is due to noise and non-linearity of the A/D and D/A converters at the low end of their range. As noted, the 24-bit and higher bit rate cards are appropriate for uses like SDR and LP-Pan. 73, Jim K9YC From gerryleary99 at icloud.com Wed Nov 12 06:30:59 2014 From: gerryleary99 at icloud.com (Gerry leary) Date: Wed, 12 Nov 2014 04:30:59 -0700 Subject: [Elecraft] KX3 Audio Compressor In-Reply-To: <8A43A6BD-4A1D-4D92-A097-ABDB94C7D837@elecraft.com> References: <54623C0D.3040800@gmail.com> <8A43A6BD-4A1D-4D92-A097-ABDB94C7D837@elecraft.com> Message-ID: <319F1DAC-3320-4078-AE12-679C5FE5E04B@icloud.com> I still have not connected my KSPA100 yet, because the KX3 gets excellent Audio reports every time.

Yes, it works. The headphone out to the K3 is good enough for all ham uses. The mic input is NOT good enough -- as has been noted, mic inputs tend to be very noisy, so they don't allow decoding of weaker signals. The difference can easily be 10 dB (10x the power). THAT'S why anyone serious about digital modes needs a dedicated USB I/O box. See the link I posted yesterday for recommendations of specific products. Or go to k9yc.com/publish.htm > Only thing missing was a way to key the K3. This is easily solved by using the RS-232 port on the K3; It's also easily solved by using VOX, which doesn't tie up a serial port.

When the computer boots, those port signals will be 'wiggled' active as the OS tests the ports. It does not matter if the signals appear in a real serial port or a USB to serial adapter - it will still happen. If you are using DTR or RTS for either PTT or keying, you should be aware. The 'cure' is to put the K3 in TX TEST if you have to boot the computer with the K3 powered on, or boot the computer before powering the K3. There is no other way to prevent this behavior that I know about. So take your pick of the method to put the transceiver into transmit when using digital modes, but be aware of what happens on the computer end and take steps so it does not create a problem or a surprise (or cause calls to Elecraft support unnecessarily). 73, Don W3FPR On 11/12/2014 1:53 PM, dmoes at nexicom.net wrote: > > The best is to key PTT via the serial port either use RTS or a > command. most good digital programs will do this for you.

Unfortunately, no. One of the first things I tried.

If it's Field Day, I assume you're using RTTY or trying for satellite QSOs. The internal sound cards can be sort of OK for most RTTY signals, but the outboard adapter will help for the weak ones. And for other digital modes, I would REALLY want the outboard interface. 73, Jim K9YC From kengkopp at gmail.com Wed Nov 12 16:20:42 2014 From: kengkopp at gmail.com (Ken G Kopp) Date: Wed, 12 Nov 2014 14:20:42 -0700 Subject: [Elecraft] Hardrock-50 kit review Message-ID: There's a review of the Hardrock-50 amplifier kit written by Phil Salas, AD5X in the December QST. 73 Ken - K0PP From wes at triconet.org Wed Nov 12 17:01:57 2014 From: wes at triconet.org (Wes (N7WS)) Date: Wed, 12 Nov 2014 15:01:57 -0700 Subject: [Elecraft] Suggestions for good 192kHz external sound card for digital modes In-Reply-To: <1850232246.8341474.1415754618043.JavaMail.zimbra@comcast.net> References: <1850232246.8341474.1415754618043.JavaMail.zimbra@comcast.net> Message-ID: <5463D8D5.4060004@triconet.org> Operationally, at least with a K3 and the modes I operate I've seen no difference between the built-in sound card on my Lenovo T400, a TASCAM US-100 or a SignaLink. Admittedly, I haven't yet tried the digital modes that dig out imaginary signals from the noise, but on RTTY and PSK I simply can't see an advantage to a better sound card. My T400 is what I use. I sold the SignaLink, so I can no longer compare but I just did a quick test on the other two. Using Spectrum Lab and listening to my Elecraft XG2 on 14 MHz with the K3 line out into the sound card, the SNR with either the T400 or the Tascam is about 50 dB. This is with the XG2 set to low power (~S3), AGC off, 400 Hz crystal filter. The filter shape is easily seen and disconnecting either card drops the baseline noise about 30 dB. I say "about" because about is good enough. The T400 is slightly microphonic but this is only seen with no audio input. IMHO, the SNR is set by the receiver and the defects in any practical sound card are, excuse the pun, in the noise. I'm looking at a couple of KHz of audio, why would I need a 192KHz, 24 bit card? (Actually, the T400 card is such) All of the other hand wringing about PTT, Windows sounds, etc, are just that, hand wringing. Turn off Windows sounds, turn on VOX and enjoy.

I see the Tascam mentioned in the PDF in the other thread, so I'm looking into those (the ones that support 192kHz now, that is) - are there any other suggestions to look into? I operate on a lot of digital modes, but my Lenovo Thinkpad T400's built in sound card adds a lot of noise to the signal I'm receiving. I have a Native Instruments Audio Kontrol 1 which works much better, but it is USB powered (it seemed to be indicated this was a no-no for best decoding in digital modes in the other thread). There are a lot of options out there now, so it's hard to sift through them all, and make a guess as to which are best for HF radio digital communication, so I thought a thread would be helpful in getting some ideas on what is tested/true. If Linux support is unknown, that's ok - I can do that research - but it would be great to have a list to start looking at that are known good performers with low noise. Thanks!

I don't disagree much with that, Wes. Although it might make a difference with weak signals in those modes, it's not easy to test in a quantifiable way. But it matters a lot for digital modes that work near the noise floor. 73, Jim K9YC From gary.hvizdak at cfl.rr.com Wed Nov 12 16:03:32 2014 From: gary.hvizdak at cfl.rr.com (Gary W.

The only issue at all is the digital connections between the radio, the amp and the PC. I put together a short tutorial which I think explains it better than the ACOM manual does. It is copied below. If you have any questions, feel free to contact me directly. You won't be disappointed. 73, Bill W6WRT dezrat at outlook.com +++++++++++++++++++++++++++++++++++++++++++++++++++ When operating an ACOM 2000A with an Elecraft K3, there are two possible modes of frequency control. Each mode requires a different cable. When a PC is NOT connected: Use a cable like that shown in figure 7.6 of the ACOM 2000A manual. You should set the K3 AUTOINF menu option to "nor", the default. In this mode the 2000A will poll the K3 for band data and will change bands accordingly. The K3 will also send band data when you manually change bands on the K3. When a PC IS connected: Use the cable shown in figure 7.2 in the 2000A manual. You should set the K3 AUTOINF menu option to "nor", the default. Note that this cable does NOT have the TXD wire going to the ACOM 2000A, but it does have the TXD wire running between the legs of the Y connector. This cable can be either a single cable terminating in two DB-9 connectors or it can be a single cable with a "Y" adaptor connected at the DB-9 end. In either case, it must be the electrical equivalent of figure 7.2. In this mode, the ACOM 2000A gets band data information ONLY from the logging program, not from the K3. If you close the logging program, the ACOM 2000A will NOT follow band changes from the K3. You can still do band changes by sending a "dit" as explained in the ACOM 2000A manual.

I have an inexpensive mic/headset that has a three connector plug (TRS). If I plug it into the Mic jack on the KX3, it works fine, although I have to use VOX, which, having an 18 month old in the house, is not a good choice! I've only made a few SSB QSO's (I'm primarily a CW op), but audio reports I get lead me to believe this mic is acceptable. OK, while on CW I don't always like using QSK. So I built a small PTT switch that has a momentary button and an on/off toggle switch. I plug this into the mic jack. It has a four connector plug - TRRS. My switches short ring 1 and ring 2 together. Works great. When I decided to try some occasional SSB, I had the problem of only ONE mic jack. So, I purchased an "octopus" connector. It has one TRRS male plug and three female TRRS jacks. I plug my headset mic into one jack and my homebrew PTT switch into another. When I'm on CW, all works fine - I press the PTT, the KX3 goes into transmit and I send CW with my paddle. But on SSB, things no longer work. If I put the KX3 into VOX, that works. If I put the KX3 into PTT mode and press my PTT switch, the radio goes into transmit, but speaking into the mic produces no audio! I put my VOM on the octopus leads. They are all as they should be - straight through on each connector - nothing cross connected. I've tried it with MIC BTN set to OFF and PTT. Neither makes it work. What do I have set wrong that's causing this strange behavior?

As alternative, you can use the ACC2 jack (2.5 mm) to wire in a PTT switch. This is discussed in the KX3 owner's manual -- see the ACC2 IO menu entry. This would allow you to use the mic jack with your headset/mic.

In-Reply-To: References: Message-ID: <546416A7.2040705@embarqmail.com> Jim, Since most soundcard data applications will allow the TX frequency and the RX frequency to be different on the waterfall, there is usually no need to put the K3 into split mode unless the offset is greater than the 2.7 kHz bandpass. Check your WJST software to see if it can lock the TX frequency while allowing the RX frequency to be changed via mouse-click. Yes, the K3 can do split in DATA A mode, but you must double tap the A>B button to transfer the mode and other settings as well as the frequency ( a single tap transfers only the frequency). When operating from a waterfall display, it may be easier to use the computer software to set the split. Refer to the help file for the software application. If using MMTTY or other single frequency software for RTTY, then the 'rules' are different, and in that case, you should be using AFSK A and yes, in that case, you want to put the K3 into split operation. 73, Don W3FPR On 11/12/2014 8:45 PM, Jim Miller wrote: > Is there a technical reason why split isn't available in DATA-A? > > It would be nice to use since DATA-A nukes all the equalization stuff and > would allow WSJT to do split as needed. > > jim ab3cv > ______________________________________________________________ > 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 jim at audiosystemsgroup.com Wed Nov 12 21:30:48 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 12 Nov 2014 18:30:48 -0800 Subject: [Elecraft] [K3] Split N/A in DATA A?

Its that simple. I have two RS audio cables to interconnect K3 line-in and line-out to my soundcard and my Elecraft USB/RS232 adapter cable to provide keying. For my applications I have PTT-KEY: DTR-RTS so that DTR keys PTT and RTS provides CW keying. This probably differs by the digital sw you use. Soundcard set up is much simpler since I use the emu-0202 which has HI-Z line-in jacks with manual level controls to set proper receive audio for the computer. I read the manual for the emu-0202 and set up the soundcard. You guys do read your manuals don't you? I use the headphone jack on the emu-0202 for connection to the K3 line-in (Tx) because it has audio level knob. That is easy as you go into your sw and key up with a test tone* while adjusting level and monitoring the K3 ALC meter = 4 steady bars with 5th flickering. *This is available on WSJT which is my main sw used. For other sw just set the K3 into TEST mode and key up with the sw to adjust level on the K3. I have LINE=10 on my K3 (press MIC knob to display LINE and set). I have no issue with computer sounds because the emu-0202 is not my main soundcard. Also easy enough to turn them off. I avoid keying the K3 when I boot-up my computer by always turning on the computer first and waiting for it to launch its applications. I am mainly running WSJT10, WSPR2, MAP65v2, and FL-digi. So there may be some "gotcha's" if you run other ham sw. I'd guess they have set up and operating manuals? 73, Ed - KL7UW PS: If you are not running a K3 an interface "may" be necessary. -------------------- From: RIchard Williams via Elecraft To: "elecraft at mailman.qth.net" Subject: Re: [Elecraft] Signalink and K3 (you do not need need a Signal Link) Jorge, Interesting enough, at a recent club meeting, the presentation was on using the SignalLink as an interface between your radio and computer to operate Winmore using RMS Express. ? Until reading all the threads the last couple of days, I was contemplating purchasing a SignalLink; ?however, last night I tried hooking my K3 directly to my computer. All I did was connect the line out on the K3 to the mic in on the computer (using a stereo cable) and the line in on the K3 to the headphone jack on the computer. ? Only thing missing was a way to key the K3. ? This is easily solved by using the RS-232 port on the K3; ?hook the K3 RS-232 port to your computer (since my computer does not have a RS-232 port, I used a RS-232 to USB dongle). ?First go to the config menu in the K3 and find "PTT -- Key"; ?set either DTS or RTS above "PTT" to on. ? Now open RMS express; in the setup there is a "PTT Port (optional) setup. ?Just selected the correct serial port (found in control panel/device manager), baud rate you selected in the K3 config menu, and use either RTS or DTS for keying (the same as you set in the K3 config "PTT --Key" setting). Fired everything up, set the Line out gain (I found 3 to work fine), then go to menu and select "Line In" and set the mic gain to an appropriate level (4 worked for me); that was it, and I was able to establish Winmor connections on 80 and 40 meters.

Causes can be as simple as forgetting to tighten the shell of a PL259, or the mic cable shield coming undone, or the mic cord connector wearing out.

Does the K2 drop out of transmit if you remove the mic plug from the K2? Any chance you are using the LOCK button on the mic instead of the PTT button? Do the two buttons have some 'goo' in them holding them in the active position for a time (slow button release)? Is the spring which restores the PTT button to the rest position weak? 73, Don W3FPR On 11/13/2014 9:54 AM, Leroy Marion wrote: > Here is a different problem for K2 gurus: > > > > Using a Kenwood MC-60, when keyed it toggles the K2 into transmit, > > and won't come out of transmit until you cycle power switch. > > Hand mic or Heil with foot switch works fine. > > Batteries in or out of MC-60 makes no difference.

If this has been discussed or otherwise, a pointer to the data would be great. When selecting filters for various operational modes on the K3, I was wondering if the 6k filter is ?Required? for ESSB operation, or if the 13k filter will suffice? Reads: I was informed that I can TX AM via the 13k filter and did not necessarily NEED the 6k filter for same. I am curious if this is also true for the ESSB mode. I am about to complete my filter compliment, and wish to efficiently utilize the five(5) available filter slots for maximum operational flexibility. This will be the primary filter configuration on the main RX. I may or may not take a different set of decisions with respect to the sub RX (to be installed). Thank you in advance.

Oh, one last thing - first barefoot QSO after getting this going: W1AW/1 in RI on 12 meter SSB; answered me on the first call with a big pileup underneath!

If you hold the BSET button it will momentarily flash which antenna is being used by the SUB RX on the lower display. You probably want to be using the same antenna as your MAIN RX so you want to see MAIN on the lower display and not AUX. 73, Mike K2MK mike wrote > Sub receiver all of sudden does not produce signal.

One would have to assume that one of the three switches has a moderate resistance when open (not completely open) that is just low enough to keep the rig keyed but not low enough to key the rig when plugged in. I'd start by testing PTT with just the base to eliminate the switch in the mic itself, then try putting a piece of paper between the NO contacts of the LOCK switch while operating the PTT, then in the PTT switch while operating the Lock switch. Isolating the individual switches should allow you to locate the source of the problem. 73, ... Joe, W4TV On 2014-11-13 11:47 AM, Phil Wheeler wrote: > eleMy MC-60 acts similarly.

As suggested I rechecked the DC voltages on Q6 and got 1.03 V on the base and 0.25 V on the emitter. The difference is 0.79 V - high, but plausible. The emitter resistor R50 measures 1.4 ohms...OK. R93 measures 809 ohms....OK. R94 measures 83 ohms...OK. C150 is marked 331J...OK. Q20 seems to be working fine. W6 to ground measures 1kohm...OK. The ungrounded end of C212 is grounded for DC regardless of which band is selected...OK. RF voltage is seen on Q212 only on 24 and 28 MHz, so the correct filter is selected on those bands. 8T applied to D1 is fine. I measured the Q7/Q8 resistances per the manual. With the positive lead on the base I measured around 520 ohms to emitter and collector. With the negative lead on the base I get about 750 ohms to emitter and about 5k to the collector. The 750 ohm number seems a bit low and might indicate something. Here's my RF voltage measurement results for various requested power settings. These are actually the DC voltage displayed on a DMM using the RF probe circuit described in the K2 manual (though not using the Elecraft board). At W6 (in mV) MHz 1W 5W 10W 3.5 3 10 16 7 4 14 26 10 3 11 22 14 7 25 31 18 5 9 9 21 2 4 4 24 7 8 8 28 11 11 11 The lack of change at higher power levels on the higher bands seems to agree with the fact that the K2 output power stops increasing as the power knob is advanced. At Q5 collector (in V) MHz 1W 5W 10W 3.5 .088 .175 .25 7 .024 .070 .11 10 .080 .22 .34 14 .166 .36 .42 18 .35 .51 .51 21 .46 .72 .72 24 .60 .64 .64 28 .73 .76 .75 We see much higher output and less variation with power setting on the higher bands. This seems consistent with a following stage having gain roll off at the higher frequencies. At Q6 collector (in V) MHz 1W 5W 10W 3.5 .89 1.5 2.2 7 .90 1.7 2.2 10 1.0 2.1 3.1 14 1.1 2.4 2.8 18 1.6 2.5 2.5 21 2.1 3.1 3.1 24 2.5 2.7 2.7 28 2.9 3.1 3.1 Same behaviour here. At Q7/Q8 base (in V, no 1 W setting, not all frequencies measured at 10 W setting) MHz 5W 10W 3.5 .39/.41 -/- 7 .40/.40 .57/.62 10 .37/.36 -/- 14 .31/.35 .37/.42 18 .35/.33 -/- 21 .40/.40 .39/.37 24 .29/.33 -/- 28 .26/.29 .26/.28 Now we see lower voltages at the higher frequencies, despite what was seen at the collector of Q6. This is probably consistent with the lower base impedance as frequency increases (though feedback will modify this). At Q7/Q8 collector (in V, only some frequencies and no 1 W setting) MHz 5W 10W 7 5.1/5.3 7.0/7.1 14 5.4/5.3 6.2/6.1 21 4.6/4.8 4.6/4.9 28 3.6/3.8 3.2/3.4 The output voltage drops with frequency and increases with power setting only at the lower bands, which is consistent with what is seen on the power meter. My best guess is that one of the finals (Q7 or Q8) is bad, but it isn't completely clear since the manual only gives RF voltages for 40m and I don't know how it is supposed to vary over frequency. Any clues here for those more familiar with troubleshooting the K2? 73, Steve VE3SMA ----- Original Message ----- From: Don Wilhelm Sent: Sunday, November 9, 2014 4:26 PM Subject: Re: [Elecraft] [K2] Low TX Output on Higher Bands Steve, Re-check the voltage on Q6. The emitter should be 0.6 volts *lower* than the base - which should put it at the manual's voltage of 0.4 volts. The power setting should not matter for that measurement. Check the emitter resistor on U6 - it should be 1.5 ohms. If this is a K2 below SN3000 without the A to B upgrades, R50 may be a 1/4 watt resistor, and it was replaced with a 1/2 watt resistor. If R50 has been overheated, it is conceivable that its resistance is lower than the 1.5 ohms. Another thing to check is the TX buffer stage U9. First measure the DC voltage at pin 3 - if Q20 is working properly, it will be at 12 volts (or power supply voltage) during receive, but drop to 1/2 that value during transmit (or TUNE). If it does not change, replace Q20 (2N7000 which is static sensitive). Also check the resistance of R93 (820 ohms) and R94 (82 ohms) as well as the value of C150 (330pF). Note that R94 and C150 are in series which makes the gain of U9 greater as the frequency is increased. 73, Don W3FPR From rwmacdonald at charter.net Thu Nov 13 17:04:46 2014 From: rwmacdonald at charter.net (W8RJ) Date: Thu, 13 Nov 2014 15:04:46 -0700 (MST) Subject: [Elecraft] RoMac IDer In-Reply-To: <1415851890253-7594677.post@n2.nabble.com> References: <1415851890253-7594677.post@n2.nabble.com> Message-ID: <1415916286594-7594699.post@n2.nabble.com> Cable the output (Speakers/Line Out, etc) of a soundcard (normally the green jack) to the Line In on the back of the K3.

I have tried this with various modes and digital programs, does it every time, on several different bands. I prefer to run at 5 watts but I guess the easy solution is to run at 15 or 20 watts. Any help or ideas would be appreciated.

After tuning, use manual mode so that it doesn't "go hunting". This seems to be especially true for CW/SSB, where power varies between zero and X watts.

It is not designed as a QRP tuner. It can be used at 5W levels, thought we do not guarantee this, if it is pre-tuned first at higher power (20 W +) on each freq and then run in manual mode (which still auto-reads the frequency and selects the correct prior tune for that range). That should prevent most false frequency counts at 5W. Your WSJT power envelope will drop well below its 5W peak during transmission, causing the frequency counter to get multiple incorrect counts and generating a spurious re-tune when operating in auto-tune mode. The frequency counter in the KAT500 works best during regular TX for signals that are primarily peaking above the 20W range. Also, make sure you have the latest KAT500 firmware loaded in your unit. We have made significant improvements to the frequency counting and tuning algorithms since our earliest shipped units. Personally, even when running my KPA500 with the KAT500 at 500 W operating levels, I use auto-tune mode and 20-50 W to train the tuner to my antennas on each frequency with a CW carrier, and then run it in manual mode at 500+ W from that point for normal operating. 73, Eric elecraft.com On 11/13/2014 2:30 PM, ejkkjh at gmail.com wrote: > I have been doing some testing using WSJT-X, and other digital modes, with my K3 an my Signalink USB. > Receive works pretty good with decodes on WSJT-X at ?19 to an occasional decode at ?24. > On transmit using various digital software and modes, when I transmit at 5 watts the KAT500 has problems. > I tune up with 20 watts, all is fine, 1.0 swr.

If I transmit with the power above about 10 watts, clear up to 100, everything works perfect? The reason the KAT500 is misbehaving is that it is a high power antenna tuner. Last I looked, 10W was the minimum power for tuning. That's why Gary advised you to take it out of Auto mode once you've trained it with higher power and stored settings. 73, Jim K9YC From k6dgw at foothill.net Thu Nov 13 19:24:54 2014 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 13 Nov 2014 16:24:54 -0800 Subject: [Elecraft] K3 and KAT500 low power problems In-Reply-To: <54654877.70009@audiosystemsgroup.com> References: <8BB7FA43196D4BE98C3CF2BE9455EE47@ejhPC> <54654877.70009@audiosystemsgroup.com> Message-ID: <54654BD6.2060609@foothill.net> On 11/13/2014 4:10 PM, Jim Brown wrote: > The reason the KAT500 is misbehaving is that it is a high power antenna > tuner.

Mine wants to see a tune power of 20 - 25W for reliable tuning. I "trained it" on each segment, and normally run it in MAN mode. It recalls the settings almost instantly. Only annoyance for me is when it rains, the window-line changes characteristics just a little. California is in a deep drought however, so rain is scarce and this is a problem with *my* antenna system, not the KAT500. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the 2015 Cal QSO Party 3-4 Oct 2015 - www.cqp.org From wa6dzs at gmail.com Thu Nov 13 23:13:33 2014 From: wa6dzs at gmail.com (Philip Barnes-Roberts) Date: Thu, 13 Nov 2014 20:13:33 -0800 Subject: [Elecraft] MC-60 microphone Message-ID: Message: 12 Date: Thu, 13 Nov 2014 09:14:12 -0800 From: Phil Hystad To: Phil Wheeler Cc: Elecraft Reflector Subject: Re: [Elecraft] MC-60 microphone Message-ID: Content-Type: text/plain; charset=us-ascii I once had an MC-60 mic, brand new at the time several years ago.

Problem: I posted the problem outlined below to the MixW Yahoo group I manage, after posting it here. This group correctly tagged the issue as a MixW issue, which I was not sure I believed until K9JWI, Clyde solved this problem as outlined below. Problem: When using the K3 and MixW, (3.11 March 4th, 2012, or as it is sometimes called MixW 3.11h), and selecting Kenwood/K3, (either 2 CH, or non 2 CH), from the rig configuration within MixW, the following actions would occur: A. If "CW is LSB" is checked, (in MixW Serial port configuration), on all bands above and including 21 MHz, the signal on the waterfall and the tuning indicator on the waterfall would operate as expected. i.e. the rig/MixW worked fine. Signal tracked waterfall frequency display. B. If "CW is LSB" is checked on any band below 21 MHz., the tuning indicator on the top of the waterfall would work as expected, however the signal would move in the opposite direction of tuning, (no longer tracking Waterfall frequency), i.e. as I tune up, the waterfall frequency indicator moved in the correct direction, and the signal would take off in the opposite direction. C. Workaround: Unchecking "CW is LSB", would correct the action described in B above, (making the rig work as expected), and break it as described above in A above. D. After posting this to the MixW list, and after several people looked into it, the decision was made that MixW was handling the "CW is LSB" in error, and that the K3 and all macros were fine. Several days later Clyde popped up with this message: ==========CUT========== Dave & Colin, Here is some more fuel for the fire. In CAT settings check "CW is LSB" and select "All Kenwoods" instead of "Elecraft K2,K3". Then all works as expected here. Align works properly on all bands. Signal traces on the waterfall move along with the frequency scale instead of in the opposite direction. All without having to check and uncheck "CW is LSB" depending on which band is in use. Why? 73, Clyde K9JWI ===========CUT========= While I can't answer Clyde's question yet, this pretty well confirms that MixW's implementation for K3 rig control is bogon, and should not be used. The K3 is not at fault in any way for this. This however did not seem to fix the issue of MixW spraying out a lot of excess data for control of the rig when it comes to tuning. The thumbwheel tuning still lags quite a bit... This pretty well gets me back to where I was with my Icom 756 PRO III for rig control, and I like the radio better, so I am a lot happier with my K3 now... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info From idarack at gmail.com Fri Nov 14 17:53:59 2014 From: idarack at gmail.com (Irwin Darack) Date: Fri, 14 Nov 2014 17:53:59 -0500 Subject: [Elecraft] KXPA100 Firmware upgrade Message-ID: In preparation for the upcoming ARRL Sweepstakes, I checked the firmware versions for my KX3, KXPA100 & PX3.

One leg of the Y cable is very short so you'll need a serial extension cable. There's a good drawing from SteppIR that shows how the Y cable connects to the multiple devices. Not specifically the K3 but any transceiver. E-mail me directly if you need a copy. k2mk at comcast dot net Change the K3 config setting: CONFIG:AUTOINF to Auto 1 Of course you'll need the transceiver tracking option on the SteppIR controller and on the SteppIR transceiver setup screen set: MODE = KENW Din should match your current K3 and PC baud rate. The Y cable leg that normally goes to the transceiver will go to the P3 serial input and then the P3 serial output will go to the K3. 73, Mike K2MK pkhjr wrote > Want my steppir to track my K3, is the Y cable from steppir all I need?

When at the remote site, set the RF and AF gain controls to your most commonly-used positions. There are various events that cause the remote K3 to reset the gain levels to whatever those pots are physically set to - notably turning on or off the sub-receiver. It's rather annoying when trying to work a weak DXpedition running split on SSB, and I/we need to bug Wayne about this again :) 73, ~iain / N6ML From elecraft at mailman.qth.net Sat Nov 15 13:13:06 2014 From: elecraft at mailman.qth.net (Wim Dewilder via Elecraft) Date: Sat, 15 Nov 2014 18:13:06 +0000 (UTC) Subject: [Elecraft] For Sale LP-PAN + EMU0202 sound card for Panadapter Message-ID: <732232562.658607.1416075186040.JavaMail.yahoo@jws10067.mail.ne1.yahoo.com> The LP PAN and EMU have been sold, thanks Alan From w3fpr at embarqmail.com Sat Nov 15 13:21:46 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Sat, 15 Nov 2014 13:21:46 -0500 Subject: [Elecraft] K1 Power Out flaky In-Reply-To: References: Message-ID: <546799BA.30408@embarqmail.com> Dave, That sounds like the behavior of an unsoldered or poorly soldered connection that is heating when you transmit. I don't know where to tell you to start looking, but if you want to shorten the search, you might be able to tell something from the Transmit Signal Tracing steps in the back of the manual. It has a chance of leading you to the failing stage and then you can examine that stage in detail. Alternately, you can reflow the soldering over the entire RF Board with a hot (750 degF) iron and dwell on each connection long enough to watch the solder melt and flow. 73, Don W3FPR On 11/15/2014 11:02 AM, w1dwz w1dwz wrote: > I am an ELECRAFT Newbie.

Of course, the integration isn't quite as tight as it is with the KPA100+KAT100. For example, when I change bands, I need to hit the "dit" paddle to give the amp/tuner a squirt of RF and let it know my new QRG. But the tuner immediately selects the right antenna and recalls the last tuning solution for that band segment. I also set the power knob to 3W when doing a tuning cycle, and then maybe crank it up to 5W if I want a full 100W out of the amp. In order to make the amp work the the K2, you need a key out line. The basic K2 doesn't have this, but it is easy to add one. Here is what I did, based on an article from the Elecraft website: http://www.mwrs.org.au/2014/04/20/elecraft-k2-amplifier-keying-circuit/ The benefit of using KXPA100 solution is that I can leave it at home if I want to take my K2+built in QRP ATU out into the field, or I can bring it along. I can also use the KXPA100 with my KX3, in which case it is a fully integrated solution. The KXPA100 is completely silent, with no fans, and relays only used for antenna selection/tuning/protection, whereas I understand the KPA100 has some noisy fans when it warms up. Whichever way you go, the K2 is a lot of fun :-) 73, Matt VK2RQ > On 16 Nov 2014, at 6:33 am, Ken Miller wrote: > > All, > > Have updated the firmware and put in the keying mods on my K2.

I had to pay extra to add one into my QRP K2. Of course if you are swapping the top of your K2 to change between "QRP" and "QRO" modes, then you might want a KIO2 for the QRP lid anyway. Of course, you can run a K2 fitted with a KPA100 in QRP mode by powering it off the coaxial power connected instead of the Anderson power pole input, but then you won't have a KAT2 ATU, and will need something external.

Some of them work some of the time, if you're lucky. I've found ones that deal with anything more than screen, mouse and keyboard tend to go belly-up with emulators.

The KXPA100 (and KXAT100) take a dit or two to 'sync up' with the K2, but other than that it works quite nicely. OTOH, the KPA100 and KAT100 follow the K2 band changes automatically. But if you are mounting the KPA100 and KAT100-2 in an external EC2 enclosure, you will need the KIO2 (or a special cable to pipe the required internal signals to the EC2 enclosure if you do not wish to have a computer control connection). You do not need the amp keying circuit with the KPA100. So those are the requirements for either setup, take your pick. The price of the KPA100, KAT100-2 and EC2 enclosure is about 3/4 the cost of the KXPA100 and KXAT100 kits - no soldering with the latter. 73, Don W3FPR On 11/15/2014 2:33 PM, Ken Miller wrote: > All, > > Have updated the firmware and put in the keying mods on my K2.

It is absolutely seamless. There are some danger, danger issues with the cabling, like do not use a normal RS232 cord from it to a PC...destructions. Only the three basic RS232 leads are for computer. The rest of the pins are used to talk to the KPA100 and KAT100. The DB9 connection on the back of the K2 is proprietary, period. I have a split cable that breaks up into a regular three wire RS232 >From K2 to the computer, and another cable from K2 to the KPA/KAT100. You can build it or occasionally an already built KPA/KAT100/EC2 will show up for sale, or a WTB posting can stir up one gone surplus. The latter is how I got mine, third hand, originally built by one of the first to ever make one. I don't have anything else like my K2/10/Battery. In simply awful 160/80m situations very close to 50 kW BC stations, where the analyzers just give up, I can use the portable battery K2 and tune something by SWR. Can directly test an antenna and listen to received signals. I'll be keeping mine. The only conversion I might try is to a lithium ion battery pack with smart charger and solar panel controller to replace the stock SLA. So the back-end PA/tuner allows me to use the K2/10 in the station with a very simple hookup to the EC2, and the EC2 retains all the fixed station hookups. The K2 with the back-end is a good 2nd radio in a contest. And plenty good enough for casual if the K3 goes on a trip. 73, Guy K2AV On Sat, Nov 15, 2014 at 6:46 PM, Kevin Stover wrote: > KPA100 wins hands down. > The KXPA100 won't integrate with the K2 nearly as well as the KPA100 which > was designed for the K2. > There's nothing the KXP100 can do for the K2 that the KPA100 can't > do....better. > > -- > R.

I have both a vertical and a beam. I run a K3 with KPA500 in the shack. I have no relays. When changing frequencies within a band the antennas are pretty fast. When changing bands, especially from say 80 to 10 or 40 -15 it can take several seconds for the antenna to adjust. I've never run into a situation where I thought I had to transmit faster than the antenna can adjust. I simply wait until the tuning led on the antenna controller goes out and then I can transmit. I'm not sure what could possibly be so urgent that I might have to transmit before the antenna stops adjusting. No danger to the K3 or the KPA500 by showing a tiny bit of patience.

I have read many digests both from here and on the Elecraft KX3 Yahoo group. Greg (K2UM) has the same issue and so does one other person (call, name uncertain). So, I am posting this here in hopes it has happened to someone and they have a solution. In an attempt to update to 2.25, the MCU load failed. If just froze during the process. After waiting a reasonable amount of time (20 minutes) to complete,I closed the Utility and tried to manually restart the KX3. No luck. I don't have batteries in my KX3 so I pulled the power and then tried to bring up the radio. "MCU LD" still stuck on the display. Tried the hold power buttons down for 10 seconds and all that outlined in the Help topic in the KX3 Utility. No luck. As a last resort, I figured I would just EEINT and reload config file or re-calibrate. The radio will not EEINT. I have left power off overnight and tried many steps to revive it this morning.

I too have a SteppIR vertical and have been running it with my FT450D and YT450D LDG autotuner. They work well in combination - and as you say quick. I will soon be at the point of crossing over to attaching the K3 with internal 100 watt amp to the SteppIR. Hence your note to the Elecract mailman list caught my eye. I haven't read up yet on how automatic I can make that and how I might interact with the KAT3 internal tuner option I added to the K3. Don't anticipate any problems.

I just went through the same exercise with a K3 I'm rebuilding. On loading it the first time, the load failed mid-step. Trying to redo the firmware load, the utility couldn't even find a K3 attached. But it was because of the state of the serial port driver (or hardware maybe), not some failure at the K3 or within the K3 Utility program. In this case, I only had to exit the utility and cycle power on the USB hub with the serial converter attached. After doing that, the utility found the K3 in its "waiting for firmware load" state. This same scenario has played out with the KX3 as well. Rebooting the computer with nothing attached at the serial port would (should) work just as well. 73, matt W6NIA On Sun, 16 Nov 2014 09:42:44 -0800, you wrote: >This may sound stupid, but reboot the computer and try again.

The page is titled "MCU Boot Loader Troubleshooting". It describes a procedure to recover from interrupted firmware loads. One of several steps suggested include rebooting the computer to start the USB device driver from a known state. There are other important steps as well. EEINIT has to do with clearing the microcontrollers' EEPROM. The microcontroller we use stores firmware in one memory space (the "program memory") and EEPROM is a different area entirely. EEINIT does not influence the program (firmware) store. The "program memory" is changed by the firmware load process. EEPROM is changed by EEINIT and by normal operation of the radio. Loading firmware doesn't change EEPROM. (But the new firmware does immediately read that EEPROM on startup). The front panel steps needed to perform EEINIT depend on program code in installed firmware, so it's reasonable that you wouldn't be able to perform that procedure without proper firmware installed. 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Randy Diddel Sent: Sunday, November 16, 2014 8:44 AM To: elecraft at mailman.qth.net Subject: [Elecraft] KX3 bricked by F/W upgrade attempt Hello Elecrafters, First of all let me say that I have RTFM, and RTFHF (read the freaking help file) before posting this. I have read many digests both from here and on the Elecraft KX3 Yahoo group. Greg (K2UM) has the same issue and so does one other person (call, name uncertain). So, I am posting this here in hopes it has happened to someone and they have a solution. In an attempt to update to 2.25, the MCU load failed. If just froze during the process. After waiting a reasonable amount of time (20 minutes) to complete,I closed the Utility and tried to manually restart the KX3. No luck. I don't have batteries in my KX3 so I pulled the power and then tried to bring up the radio. "MCU LD" still stuck on the display. Tried the hold power buttons down for 10 seconds and all that outlined in the Help topic in the KX3 Utility. No luck. As a last resort, I figured I would just EEINT and reload config file or re-calibrate. The radio will not EEINT. I have left power off overnight and tried many steps to revive it this morning. I will mention that I had the PX3 in line but not on. I now know to update all firmware with the USB cable directly from computer to radio. Unless Wayne, Eric, anyone else has any ideas, it looks like I may have to send the rig home for repairs. Thanks, 73.

I was failing on loading one of them and restarting it did not cure the problem. I got around the problem by loading just that specific piece of firmware. I vaguely remember seeing a bug fix for the utility that seemed to be my problem, but I could have misinterpreted the README. I haven't had the problem since. Bottom line: Try loading just that piece of firmware. Then load the others separately if they aren't up to date. 73 Bill AE6JV On 11/16/14 at 9:57 AM, mzilmer at roadrunner.com (Matt Zilmer) wrote: >It doesn't sound stupid at all, Rick.

It may be that the KX3 is just sitting there waiting for the computer to feed it some data. Because this all started during a firmware update that stopped midstream for some unknown reason, I would suggest you be suspicious of the computer, the adapter cable and anything else associated with the serial connection. You may even want to try reloading the driver for the USB to serial adapter. It would be a shame to send the KX3 back to Elecraft only to discover that there was a problem at the computer end. If you have another computer (or can borrow one) try loading the USB cable adapter driver and KX3 Utility on that computer. If you have an XG3 signal generator, try using the same cable and the XG3 Utility - the cable for the XG3 and the KX3 are the same. 73, Don W3FPR On 11/16/2014 12:32 PM, Randy Diddel wrote: > As I stated.

Background (more of it): I use a PC hooked to the KX3 in the shack but I am a Mac guy in the rest of my life. I had been trouble shooting this issue with that PC. Since I have 3 USB brand new cables from Elecraft, I decided to open one that had not been used and try updating with my trusty Macbook Air. Steps: 1. Download the FTDI USB drivers for the Mac. 2. Download KX3 Utility from Elecraft. 2b. Open Utility and make sure verbose logging, trace, and Advanced options were selected-figuring that Elecraft will want this type of information. 3. Disconnect (already was) USB serial connection from KX3-leaving only power to radio. 4. Press and hold power for 10 seconds as per help file about MCU LD. 5. Connect USB cable to Mac then to KX3 6. Open KX3 Utility try connecting to KX3-success. 7. Click on Firmware Tab and Copy New Files From Elecraft 8. Still on Firmware Tab, select MCU box and then click "Send Checked Items to KX3" Wait.....I turned on trace and verbose logging in case I needed to send error log to Elecraft so it took longer than a normal firmware update. 9. SUCESS Message stated complete (or something like that) and I look over to see the KX3 on the frequency I left it on last night. I can only speculate but perhaps the recent FTDI driver update via Windows may have been the cause (more here: http://www.adafruit.com/blog/2014/10/22/ftdi-drivers-brick-counterfeit-chips-with-latest-windows-update/ ) NOT stating that the Elecraft chips supplied are counterfeit, but rather something with that update made my PC to KX3 connection wonky. The only supporting evidence that I have is that I changed OS Platform to OS X which would have completely different drivers and hardware handling. To my knowledge, FTDI update issues like those on the PC have not been reported on OS X. BTW, I am running OS X Yosemite. Oh, and yes I could/should have switched to the Mac and used the cable hooked to the PC first to rule out a bad cable. So I violated the first rule of trouble shooting: only change one thing at a time. HI HI. So all good now! Thanks for the suggestions that got me to where I had a solution Greg and Rick! Hopefully, you have access to a different OS platform and can try it. I suspect I could reproduce this via some Linux variant if I tried. 73 K5RHD /randy On Sun, Nov 16, 2014 at 10:42 AM, Rick Bates, WA6NHC < happymoosephoto at gmail.com> wrote: > This may sound stupid, but reboot the computer and try again.

It got to pipe freezing temperatures at least two nights this week. The oddest sight of the week was seeing frozen, very wrinkled green leaves. Normally things die off before it gets this cold but the transition from 50 degree days to highs in the teens happened overnight. However, it is sunny and will remain so for most of the week. Propagation is fantastic this week. The sun has been active but non-interfering. Few flares causing blackouts but a consistent flow of ions is keeping the ionosphere well fed. Please join us this afternoon and evening. 14050 kHz at 2300z Sunday (3 PM PST Sunday) 7045 kHz at 0200z Monday (6 PM PST Sunday) 73, Kevin.

In-Reply-To: References: Message-ID: Hi Greg. I think in Yahoo Digest 3503 you posed your question. Be sure to follow up there with your results. I am posting this to the Elecraft Reflector. I am certain that the other person on the Yahoo reflector having this issue will be happy to know what you/we did.-not to mention Elecraft(but they probably already know). It does seem to point to the driver and not the cable on the Windows side! If I was willing to be scientific, I would try to brick the KX3 again and see if the first cable I used is in fact OK on the Mac but I think I will just be happy with my solution. I am going to stay away from 2.27 Beta for now and just enjoy the radio. HI HI 73! /randy On Sun, Nov 16, 2014 at 1:15 PM, Greg Buhyoff wrote: > Randy, > > You are the man!

Ready for a surprise? The FTDI driver is actually built in to Yosemite. Mavericks, too. That means you don?t need to download the driver from FTDI. Why is this important? In Yosemite, drivers must be signed. The ones on the FTDI site are not. I didn?t believe this when I first heard it, so I tried an FTDI USB device with a fresh install (not upgrade) of Yosemite. It worked! The devices were recognized and worked properly. As a developer, I was surprised since I had seen no notification about this previously. 73, and glad you have things going.

First, make sure the audio is getting into the iMic. Plug the audio cable into something that you know produces audio, like an MP3 player or a portable radio. Can you see something on the waterfall - yes, it will not look like data mod signals, but you should see some flickering of colors on the waterfall display. Adjust your iMic input level until that happens. One hint - Windows7 by default mutes the line input to any soundcard (and iMic is a soundcard), so you have to explicitly unmute it. Once you know you can get audio into the iMic and have it cause some sort of waterfall display, plug the audio cable into the radio and adjust the AF Gain, or Line Out level to obtain something on the waterfall. You might have to adjust the soundcard line in level as well. You should see a bit of blue background noise color and signal levels rising to yellows or reds. 73, Don W3FPR On 11/16/2014 4:17 PM, Millerhill wrote: > Looks like I can TX but have no receive?.no waterfall.

If you look at the specifications you will find that the KAT500 will handle 1000 watts over a 3:1 SWR range (600 watts over a 10:1 SWR range) - and that is from 3 to 30 MHz. At the 1.8 to 2 MHz frequency range, the 600 watt level is reduced to a 5:1 SWR for low impedances (still 10:1 for high impedances). At 1000 watts the rating is still for a 3:1 SWR over an impedance range of 16 to 150 ohms. So the real answer depends on your required antenna tuning range. Will it work at levels exceeding the specifications? It may, but it may exceed the maximum voltage of the capacitors and/or the maximum current of the inductors. In other words, operation beyond the limits of the specifications is at your own peril. Examine the impedance of your antennas and then you can determine the answer for your station. 73, Don W3FPR On 11/17/2014 9:14 AM, David Cole wrote: > Hi all, > > I am considering the Elecraft KAT500K tuner for my station...

My antennas are all fairly well matched. When the KAT500 doesn't like the load or the power, it faults to protect itself. If you're a reasonably technical guy who won't expect the tuner to do things it cannot do, I think you'll be very happy. I am. As Don has said, it won't let you run high power to a badly matched load. The KAT500 has three outputs, and the firmware remembers settings for each on each band (and even multiple frequencies on a band). Like the KPA500 (which I use when not contesting), all it takes is a dit or a bang on the mic to change bands and recall settings. I use no band data for either unit, and only PTT for the KPA. 73, Jim K9YC From w7ox at socal.rr.com Mon Nov 17 13:29:05 2014 From: w7ox at socal.rr.com (Phil Wheeler) Date: Mon, 17 Nov 2014 10:29:05 -0800 Subject: [Elecraft] ESSB In-Reply-To: References: Message-ID: <546A3E71.30802@socal.rr.com> I think you meant KHz, not MHz, David :-) My thinking is that the narrower "communications quality" signal would be more effective.

Change those MHz to kHz. :) The answer is "YES, MUCH stronger and punchier, more dB transmitted" with limited bandwidth. The difference is roughly one S-unit. A big part of the difference comes not from the high end, but from the low end. For best communications quality, go to TXEQ and set the three lowest bands for maximum cut, set the fourth band (400 Hz) to -6dB cut, and get signal reports. For most ham mics and voices, leave the rest of the bands flat. For mics or voices that sound a bit dull or deep, boost the top two bands by 3-6 dB. Professional mics will require more boost on the high end. We can also increase our talk power by using the compression built into the K3. Set it so that you see no more than 6-10 dB compression on peaks, using the compression display. 73, Jim K9YC From alorona at sbcglobal.net Mon Nov 17 13:48:06 2014 From: alorona at sbcglobal.net (Al Lorona) Date: Mon, 17 Nov 2014 10:48:06 -0800 Subject: [Elecraft] ESSB In-Reply-To: References: Message-ID: <1416250086.16006.YahooMailNeo@web181605.mail.ne1.yahoo.com> Your intuition is correct, David.

If you live in California (escalating rates based on monthly usage), you probably want to turn everything off when you leave the shack to save on your electricity bill. My differential rate is in the range of $0.35 per kWh, and even being frugal, I'm always subject to that rate. Back in Chicago, where I was paying in the range of $0.13 in the summer and a few pennies less in the winter, I left everything on all the time. :) 73, Jim K9YC From davidahrendts at me.com Mon Nov 17 14:01:17 2014 From: davidahrendts at me.com (David Ahrendts) Date: Mon, 17 Nov 2014 11:01:17 -0800 Subject: [Elecraft] ESSB In-Reply-To: <1416250086.16006.YahooMailNeo@web181605.mail.ne1.yahoo.com> References: <1416250086.16006.YahooMailNeo@web181605.mail.ne1.yahoo.com> Message-ID: <35A0148B-4206-49E6-AF9B-89353D240B05@me.com> Well put, Al.

If you heard Jim's signal during the SS this weekend then you got to hear what the shaping he is describing sounded like. His audio was very piercing but clean. It's not what I would want to hear during a long ragchew with him, but his purpose was to project his intelligibility across 40 meters for the purpose of a 30-second contact. Another way to look at this is that our ear is most sensitive to frequencies around 2 kHz (roughly) and so you really want to put as much of your power in that region as you can. In this way, you're using the response of the other op's ear to your advantage. To further paraphrase what Jim said, when it comes to compression, "A little is good, but more is not better," as evidenced by so many shockingly bad signals this weekend. I wish someone would undertake a project to send contesters recordings of themselves. I happened to be listening when a station with especially egregious audio called K9YC, who gave the op a quick but honest report at the end of his exchange.

Human voice has very little energy between 700 Hz and 1200 Hz with most of the power (fundamental energy from the vocal chords) between 200 and 500 Hz with sibilance and unvoiced energy (sounds made with the tongue, teeth and lips) that contribute to "definition" (consonants) in the 1400-4000+ Hz range. The ear needs a balance (although not 1:1 relationship) between lows and highs for best intelligibility. While I do not try for maximum "punch" like K9YC, what he suggests is a good starting point. I don't completely roll off 200 Hz but set it to about -6dB. I also set 800 Hz to -6 or -10 dB which helps eliminate background noise. Then I use a 3 dB/octave rise at the high end: +3 at 1600, +5 at 3400 and +6 at 3200. With the K3 compression engaged, the rise means the highs will be "more dense" (or clipped harder). They will not be any louder than the lows but they will be more pronounced through the noise and *will* contribute to enhanced intelligibility without sounding "rough," "muddy", "tinny" or "narrow". Excessive low frequency response generally causes voices to be muddy. Excessive high frequency energy with too little low frequency response causes voices to sound "tinny" and too much mid-range (excessive low and high cut) causes voices to sound hollow. 73, ...

I added a hearing aid to my only functional ear a week ago and found not only improved volume but improved freq response (in retrospect, not a surprise!). Now folks with high, "squeaky" voices are much more intelligible than they were before. The downside is using headphones: I've preferred an Apple ear bud and have quite a collection. So I'm experimenting with new headphones vs. removing the hearing aid. I tried one over the ear type, well reviewed, that resulted in a sequence of chimes in the hearing aid -- not a good sign. So now I can hear ESSB better -- but I still don't like appreciate it: Big hog of bandwidth, IMO. And it's so easily recognizable on my P3 or PX3. 73, Phil W7OX From nq5t at tx.rr.com Mon Nov 17 16:33:30 2014 From: nq5t at tx.rr.com (GRANT YOUNGMAN) Date: Mon, 17 Nov 2014 15:33:30 -0600 Subject: [Elecraft] ESSB In-Reply-To: <546A6229.3080201@socal.rr.com> References: <546A3E71.30802@socal.rr.com> <1416251100.29810.YahooMailNeo@web181602.mail.ne1.yahoo.com> <546A5A18.30902@subich.com> <546A6229.3080201@socal.rr.com> Message-ID: <84F5D7C0-915F-49D5-9B43-6655A7EAFFE4@tx.rr.com> > but I still don't like appreciate it: Big hog of bandwidth, IMO.

Not every mode has a place on every band. ESSB has no place on any band where wideband FM is not permitted due to the bandwidth. Amateur radio is a communications service, not a broadcast service and 2.7 KHz is all that is necessary for clean SSB with reasonable fidelity ... audio that does no sound tinny, muddy or hollow.

But, your answer leaves a lot of details out. So, if I am using the side tone generator to zero beat another CW station, I do two things. One, I adjust the sidetone pitch to something I prefer. Two, for the actual CW station, I adjust the VFO until the pitch of the CW signal closely matches my sidetone pitch. (I know, I could push the spot button too and I usually do that). If this is true, then the sidetone generation itself is a function of the VFO frequency, that is, it is, say, 600 Hz away for example in a BFO kind of way. I was looking for a description of more of the details of how this was implemented and I admit it is to satisfy my curiosity. Math functions don't scare me though, I did my graduate work in Math. I admit to being a bit weaker with typical DSP algorithms -- more of a philistine than a practitioner. 73, phil, K7PEH > On Nov 17, 2014, at 2:16 PM, Don Wilhelm wrote: > > Phil, > > The CW sidetone is nothing more than a set of math functions inside the DSP. > With the proper DSP code, you can make up most any kind of sound wanted, even sidetone mixed with demodulated signals.

It is not a function of the VFO, it is just a constant tone. The demodulated audio (from the signal you are listening to) does vary with the VFO setting. So yes, the selected sidetone pitch tells the DSP not only what spot pitch to send, it also is used to figure out how much frequency offset to use on the signal received as a result of the VFO setting. I can't give you the DSP math to produce that, but Lyle certainly could. I suspect the demodulated signal tones and the sidetone are simply added - that is at least the result in the analog world. I do know the BFO/signal relationship is a "mixer" process and if I recall that in DSP math is some sort of multiplication process - as you can tell, I am not well steeped in DSP techniques, but I do recall a bit of signal processing math from my college days even though that was 54 years ago and I did not use that theoretical level of it, so much has become 'fuzzy' with time. Perhaps some study of DSP algorithms would help you out. 73, Don W3FPR On 11/17/2014 5:51 PM, Phil Hystad wrote: > OK, so side tone generator is a DSP function.

The Mean Time Between Failure for any component is so great (mostly 100,000 hours or more) that it is only a minor consideration. Of greater concern is "what can happen during idle periods" - such as a lightning or other static event that can cause damage. That can happen whether the equipment is powered or not. So, when the transceiver is not in use, switch the antenna connection to a dummy load is a good preventative measure. Yes, lightning surge paths can be other than the antenna, they can come in on the AC power lines or the telco line (read as computer connections), but a connected antenna is the most likely 'gatherer' of lightning and static charges. 73, Don W3FPR On 11/17/2014 6:16 PM, W4GRJ wrote: > My question is technical not financial....

Now folks with > high, "squeaky" voices are much more intelligible than they were before. Very important topic for those of us with compromised hearing. Both my ears still work, but the bulk of my hearing disappeared in one event one night many years ago. I hear almost nothing above about 1200 Hz where both ears are about 85 dB down, without the $6,000 worth of microelectronics stuffed into my ears [fortunately, the government pays for mine :-)]. My new ones can identify music, conversation, noise, fire truck sirens, and CW, and adjust accordingly. They even talk to each other so they change programs together. > > The downside is using headphones: I've preferred an Apple ear bud and > have quite a collection.

Mine do not work under my headphones [Heil Pro-Set I got from Elecraft], they just shut down. I run the AF Gain at about 1 o'clock on CW [don't operate much SSB, too hard to understand] which is right at the beginning of distortion in the cans. I don't know if it's coming from the K3 audio amp, or the headphones are being overdriven. My CW sidetone is at 570 Hz, and I use a mark of 915 Hz on RTTY, both of which I can hear if they're loud enough. Since the hearing aids communicate with each other [if I manually turn one up or down, the other does it too ... some bluetooth-ish thing I suppose], I've wondered if there's a way to feed audio directly into them from the K3. I haven't found one yet, and I don't know if it would be better than the headphones. If the audio distortion is coming from the AF amp in the K3, an outboard amp might allow me to get higher sound levels in the headphones. If it's coming from overdriving the headphones, maybe I need a better headset/mic? If anyone has any experience driving digital hearing aids directly, I'd like to discuss it with you. My aids are Phonak Savia's. SS SSB and NAQP SSB are the only phone contests I play in, and only then to create some points for my club.

But simplifying as much as possible: - based on the sidetone setting eg. at 700Hz, the DSP will produce a sine wave audio output at 700Hz and add it to the output audio of the radio demodulator. - the frequency of local oscillator in the KX3 is set to the frequency of the signal of interest plus 700Hz, and put through a quadrature mixer. This brings the signal down to a baseband at 700Hz. - the I and Q output of the mixer is sampled by an A-D converter, and the maths mentioned in the article linked above is used to remove the opposite sideband image, and you are left wi the desired signal at 700Hz. When mixed with the 700Hz sidetone, you hear a single tone. - if you tune the VFO a bit, it moves the local oscillator, and the demodulate signal is no longer exactly at 700Hz. You will hear the resulting signal "beat" against the 700Hz generated sidetone. - when you transmit, it will be based on the sidetone frequency, eg. 700Hz. If you have zero-beating in the receiver, then you know the output of the transmitter will exactly match the received signal frequency. If we select CW-R, then we put the LO 700Hz below the signal of interest. If we select other features like IF SHFT=8kHz, dual watch, etc. then the maths gets a bit more complicated, but essentially amounts to implementing a second mixer stage in DSP software. 73, Matt VK2RQ > On 18 Nov 2014, at 11:42 am, Phil Hystad wrote: > > Don, > > Thanks for the comments.

It's not what I would want to hear during a long ragchew with him, but his purpose was to project his intelligibility across 40 meters for the purpose of a 30-second contact. Another way to look at this is that our ear is most sensitive to frequencies around 2 kHz (roughly) and so you really want to put as much of your power in that region as you can. In this way, you're using the response of the other op's ear to your advantage. To further paraphrase what Jim said, when it comes to compression, "A little is good, but more is not better," as evidenced by so many shockingly bad signals this weekend. I wish someone would undertake a project to send contesters recordings of themselves. I happened to be listening when a station with especially egregious audio called K9YC, who gave the op a quick but honest report at the end of his exchange.

I wear hearing aids in both ears. I found a device that allows me to use my hearing aids as headphones. My hearing aids are made by Widex. Wide offers a small accessory device called the MDEX, which communicates by radio waves (not Bluetooth) with the two hearing aids. The MDEX communicates by Bluetooth with cell phones and any other devices that have Bluetooth audio capability. The MDEX (which is about half the size of a pack of cigarettes) can also be connected directly to the K3 with a mini-stereo cable. In that mode, the K3 audio goes directly to my hearing aids. I can shut off room noise if I wish, or leave it to be piped into my ears along with the radio audio. More info is available at http://www.widex.com/en/products/accessories/dex/mdex/ about the MDEX device. Warning: this is not a low-budget solution to the headset problem. The hearing aids are $3K each, and the MDEX costs about $400. But it works well when I want to use the hearing aids as a headset, either for ham radio or music listening purposes. 73, Lew Lew Phelps N6LEW Pasadena, CA DM04wd Elecraft K3-10 Yaesu FT-7800 Lew at N6LEW.US www.n6lew.us ?The plural of ?anecdote? is not ?data.??

Wide offers a small accessory device called the MDEX, which communicates by radio waves (not Bluetooth) with the two hearing aids. The MDEX communicates by Bluetooth with cell phones and any other devices that have Bluetooth audio capability. The MDEX (which is about half the size of a pack of cigarettes) can also be connected directly to the K3 with a mini-stereo cable. In that mode, the K3 audio goes directly to my hearing aids.

The t/r transitions in QSK and semi-QSK CW when there are nearby strong signals make a horrible racket -- enough to make me turn down the volume when sending, which negates the utility of QSK, of course. Although the QSK is smooth and quiet on a quiet band, this is not the case when there are strong signals around. Here in 4X the EU signals can be super-strong, and in recent FT4TA pileups, the banging and crashing around my sidetone made operating sheer torture. Yes, I am using QRQ mode (I listen to the DX on the subrx and the pileup on the main so as to make this possible) and New QSK. It doesn't matter. The problem is as bad or worse in 'simplex' operation when numerous stations are calling a DX station on the same frequency. I understand that this is caused by the limitations of the synthesizers. But I have discussed with Wayne and Lyle the possibility of changing the RX muting function, which would slow down the QSK but at least make it quiet. Fast QSK is worthless if I have to turn down the audio to protect my eardrums! This would do a huge amount to increase the operating pleasure of serious CW operators. The feature could be optional so those who like to ragchew at high speed in QRM-free spots could turn it off. -- 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ From dmoes at nexicom.net Tue Nov 18 08:31:23 2014 From: dmoes at nexicom.net (david Moes) Date: Tue, 18 Nov 2014 08:31:23 -0500 Subject: [Elecraft] ESSB In-Reply-To: References: Message-ID: <546B4A2B.8090406@nexicom.net> Not sure if it was you and I cant even remember what band 40 I think, but during the contest I did run across what appeared to be a rather wide ssb signal typical of ESSB, rag chewing The audio was great sounding a little reminiscent of some the AM nets on 40m I would think that it would have less punch or diluted as you well describe it but would be much better sounding for rag chew.

Normally, the output of the amplifier would go to a tuner, like the KAT500, or whatever flavor your prefer, and then to an antenna switch to select antennas. Some people only have a couple of antennas and the 3 output connections on the tuner would suffice, but most serious hams have more than that, plus a dummy load, multiple radios, etc. You also need to consider lightning protection, depending on where in the country you live. Personally, I have the radio going to the amplifier, which goes to the tuner. From the tuner, I select either the dummy load or my active antenna, leaving one output port on the tuner unused. I have the dummy load on the default (power off) port, so that the load is on the radio/amp if the power fails. From the active antenna port on the tuner, I go to a 5 port arc suppressed antenna switch, selecting one of 4 antennas (I need more ports). I left out the multi-radio switching and other complications in this description.

CALP bypasses all the L/C elements, so if the problem is in the tuner L/C section, it will be bypassed. If the problem were in the tuner wattmeter or thru path, all bands would be affected, so you already know that is not it. More than likely, the problem is in the low pass filter, and yes I would expect a solder problem or an inadequately stripped and tinned toroid. If you have the KPA100, there is one LPF in the base K2 and yet another in the KPA100. There is also the chance that the problem is in the bandpass filter. You might try putting it in the refrigerator overnight to induce the failure -remove the top cover so you can direct the heated air at one particular spot - you my have to fabricate a narrow nozzle for the hair dryer. 73, Don W3FPR On 11/18/2014 1:22 PM, EMD wrote: > I have had my K2 (7109) for 3 years now and I have noticed something about it > when it gets cold out.

Message-ID: <0F844674D89140769877A107433DC50D@JIMDESK> I've stumbled into a strange problem. I have 4 friends with similar K3 stations to my own; K3 >>> KPA500 >>> KAT500. The stations are powered with similar power sources. One station sounds fine, works great. The other 4 had strange issues that manifested themselves as audio distortion when running the amplifier. After looking all over for RF and grounding issues, we swapped the coax cable from the K3 to the amplifier, with a longer cable (about 6 to 7 feet - largely because that was the only free cable we had handy). Making the cable from the K3 to the amplifier longer eliminated the issue. putting the cable back brought the problem back. Making a new short cable still left us with audio distortion. The only thing that seemed to solve the issue in all 4 cases was making the K3 to amplifier cable longer. This got me to investigate my own station. It turns out that the cable I used between the amplifier and the radio was about 6 feet long. Swapping this cable for a shorter length brought about audio distortion symptoms. Does anyone have any thoughts about this?

We had relocated the station and used different (shorter) coax to wire it all up. We encountered various problems the main one being a high SWR. The cables were checked but nothing untoward was found. Then one member said that we shouldn't use short cables and so we found some longer cables, about 2m long, (not the originals) and everything worked fine. We never did find out the reasoning behind not using the short cable lengths.

Since the K3 turns off the final stage when below 13 watts, does that mean running 10 watts is a bad choice since that's running the lower power stage at near maximum? From a cooling perspective alone, I have often wondered if it's better for a K3 to be run at 15w rather than 10.

I've stumbled into a strange problem. I have 4 friends with similar K3 stations to my own; K3 >>> KPA500 >>> KAT500. The stations are powered with similar power sources. One station sounds fine, works great. The other 4 had strange issues that manifested themselves as audio distortion when running the amplifier. After looking all over for RF and grounding issues, we swapped the coax cable from the K3 to the amplifier, with a longer cable (about 6 to 7 feet - largely because that was the only free cable we had handy). Making the cable from the K3 to the amplifier longer eliminated the issue. putting the cable back brought the problem back. Making a new short cable still left us with audio distortion. The only thing that seemed to solve the issue in all 4 cases was making the K3 to amplifier cable longer. This got me to investigate my own station. It turns out that the cable I used between the amplifier and the radio was about 6 feet long. Swapping this cable for a shorter length brought about audio distortion symptoms. Does anyone have any thoughts about this?

As it relates to that part of the distortion caused by compression or clipping in the amplifier chain (IF-> Low power amplifier -> PA), running the K3 at 10 watts is probably worse than running it at 20 watts. I don't have specific data on the particular devices used in the K3 but in general IMD is minimum around 80% of maximum rated output. 73, ...

Yeah sounds great, but the devil is in the details. I just finished a port to a faster refurbed multicore WIN7 machine. The task involved: 1)50 programs and data 2) 3 sound cards (4 if you include the video) 3) eight USB ports of stuff 4) five RS232 ports of stuff 5) one lpt port 6) Networking with XP computers 7) Internet I started October 23. Finally I have 98% of what I had working under XP. It took an estimated 80 hours of work and cost in excess of $500. Admittedly, I'm on the low knowledge end of OS stuff (and maybe in the majority of ham users in that regard). The most difficult parts were: 1) Device drivers. Trial and error process. 2) Sound card problems. It's a zoo. 3) Networking (it takes 15 at first unknown steps in several pull down boxes to do what a single click in XP used to do) I still have one unresolved issue with the motherboard sound. It simply won't output anything via line out. I'm almost convinced that the sound out hardware is bad. It's quite possible on the refurbed machine that the previous owner clobbered the hardware. WIN7 seems a bit flaky in sound card stuff. It isn't a trivial process unless you're just interested in E-mail, Internet browsing and a few spreadsheet programs. Thank goodness WIN7 isn't bleeding edge. I can't imagine doing this for a newly released OS.

When I read the longer cable response, I thought that it's just a change to the RF getting into something.

OEM versions will likely not have drivers for your machine (if different from the OEM's target). System Builder OS versions come with a bunch of commonplace drivers, but nothing specific to any machine. For drivers, it's best to to visit the computer OEM's support website and download what you need. You can find out what you have on the mobo by running Device Manager and scrolling through the device tree, making a list. I've had to do this three times for Win7 - once for a Samsung laptop using System Builder, and twice for Dell desktops that were slightly different from each other, each using an OEM version of Win7. It's not too big of a chore, and being thorough lets you build a platform that doesn't have any missing or improperly-configured devices (um, well in theory at least). Or maybe everyone already knows all this. :) If you have ancient software that uses the Win16 model, you can also install Virtual XP to run these apps. Microsoft doesn't support XP any more, but you can still download the VM and the XP CD image files and install them. The VM method allows running two OSs on one platform at the same time. The same method may be used to run Ubuntu Linux and other OSs in a similar way. 73, matt W6NIA On Wed, 19 Nov 2014 14:39:25 +0000, you wrote: >You often see postings here advocating abandoning XP in favor of newer >OS's.

Windows 8 or 8.1 is hardly a totally new OS - it is primarily a touch interface layered over Windows 7. If one is not using the "tablet" or Windows Phone interface on a touch enabled device, switching to the traditional desktop provides nearly the same interface as Windows 7. Coupled with some third party add-ons (like Classic Shell) the user can achieve nearly the same interface as Vista or Windows XP with the added reliability of Windows 8 under the hood. I have both Windows 7 and Windows 8.1 systems with Classic Shell and I would not bother with Windows 7 on a new system - nor would I even consider upgrading hardware that will not support Windows 8 given the sub-$500 price point of quality new i5 based systems. 73, ...

Joe made this statement assuming that the KPA500 produced FAR more distortion than it actually does. A few days later, I showed measurements with a K3 driving a KPA500 to 500W with PSK31 showing that the distortion was EXTREMELY low. I had already published comparable measurements for CW and SSB, with the same result.

I've been using T4x Thinkpads running XP for years, and they have done everything I needed, both in the shack and for some very demanding engineering applications. The newest of them, a dual core T61 that's about six years old, is very happily running N1MM+. To make it work reliably, I give it real hardware serial ports, a decent USB sound card, and use WinKey to send CW. One serial port comes from a docking station, two more from a PCMCIA card. This summer, with XP support ended, I bought a Win7 machine for my desktop that does engineering work and email, and a Win 8.1 for the XYL who does only email and A/V playback. I found the "mind of its own" of Win 8.1 to be maddening, but I very much like Win 7 once I found and read an excellent third party manual. I have a hard and fast rule to NEVER upgrade a machine to a new OS, but rather to buy a new machine with the OS I want installed. Because power is unreliable where I live, I use laptops almost exclusively. I've found that it is always a good move to buy the docking station -- for older machines, it comes with at least one real serial port, several good USB ports, and a VGA port. Bought on EBay, they're pretty inexpensive. 73, Jim K9YC From k2vco.vic at gmail.com Wed Nov 19 12:21:59 2014 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Wed, 19 Nov 2014 19:21:59 +0200 Subject: [Elecraft] K3 audio artifacts In-Reply-To: <546CC84D.301@audiosystemsgroup.com> References: <546B3B3F.80508@gmail.com> <546C744C.2090401@gmail.com> <546CC84D.301@audiosystemsgroup.com> Message-ID: <546CD1B7.5020207@gmail.com> 400 Hz, 1.0 kHz and 2.8 kHz.

Usually the 400 Hz is in use. Why? I was wondering if what you are hearing is the result of overload of the DSP. I do most contesting with a Ten Tec Titan. Although it does very good QSK, I've also had the experience of vacuum relay failures during a contest, so when I'm using it, I don't use QSK. I do use QSK in 100W contests like NAQP, and I don't remember the sort of issue you describe. Of course, other signals are 15 dB weaker too. :) I have the 8-pole 250 Hz filter, and have it engaged most of the time for CW contesting. On the lower HF bands, I usually have the Atten engaged and the preamp off. On the higher bands, Atten is off and Preamp is usually on. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Nov 19 12:41:52 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 19 Nov 2014 09:41:52 -0800 Subject: [Elecraft] OT- experience porting XP->WIN7 In-Reply-To: <546CD432.8010103@gci.net> References: <546CAB9D.1090900@nc.rr.com> <546CC105.6030408@subich.com> <546CD0A9.4060403@audiosystemsgroup.com> <546CD432.8010103@gci.net> Message-ID: <546CD660.9030709@audiosystemsgroup.com> On Wed,11/19/2014 9:32 AM, Jim Wiley wrote: > Would you be so kind as to enlighten the rest of us as to the title > and author of that Win 7 manual?

As I wrote on another list just a day or two ago, there are many reasons to upgrade both hardware and operating systems -particularly when one is using Windows XP with hardware commonly available when XP was the newest and greatest. Current hardware - particularly the mid-speed Intel i5 processor and its AMD equivalents are much faster - typically eight processor units (four hyperthreading cores) - and the support chipsets are capable of much higher data through- put (disk access rates) that there is simply no comparison when one runs multiple programs or sets of programs. For example, most of the logging (particularly contest logging) environments severely stress a single or dual core Pentium processor that was the norm before the introduction of Windows Vista. Those support chip sets do not contain the Windows High Performance Event Timer [HPET] used by 2Tone and EXTFSK 2 for bit bang FSK generation or by some loggers for CW generation. The dual core Pentium processor is simply maxed out when doing CW or FSK, logging, running Cluster, etc. not to mention trying to handle DSP necessary to run an SDR Console for sound card based Panadapter (or CW Skimmer), etc. Both operating systems and PC hardware have advanced light years in the nearly 13 years since Windows XP first appeared in preview mode and even in the eight years since Windows Vista. Those old platforms are as much off the developers' RADAR as 16 bit Windows 3.1, 95, and 98 ... reactionary attempts to keep those platforms going not withstanding. 73, ...

I specifically said "*average* power from the KPA-500 should be kept 6-10 dB below the maximum". Jim made his measurements at PEP which *includes* the crest factor (PEP = average power X Crest factor or alternately Average Power = PEP/Crest Factor). If his measurements were made at average power, the results would have been considerably different. With most PSK, MFSK, PACTOR, etc. modes, it is important that the average power output be kept low enough that none of the amplifier stages is driven into saturation on the peaks which can be anywhere from 3 dB to 13 dB greater than average depending on the digital modulation. Note: FSK, JT65 and JT9 modes are "saturated" - their crest factor is 1 (0 dB). Like CW, for those modes, PEP = average power. 73, ...

Message-ID: <546CF65D.9000008@bluewin.ch> Well, this is surprising, to say the least. Inasmuch as it seems to have happened in several places. I normally don't post remarks of the "no-problem-here" sort but I don't think this has anything to do with RFI or inductance. Neither are ferrite chokes likely to solve the problem. My K3->KPA500 cable is only 65 cm (26") long (the only piece of RG58 in my setup) but nobody mentioned any distortion. BTW: Both the K3 AND the KPA500 are earthed (grounded, if you prefer) separately to a common earth... I mean: grounding point, as well as the (manual) tuner, the SteppIR controller, etc. If a longer cable can solve the problem, it's OK but the main question (the "WHY?") remains unanswered...

In-Reply-To: <546CF65D.9000008@bluewin.ch> References: <546CF65D.9000008@bluewin.ch> Message-ID: There are certainly other possibilities. Making an amplifier unconditionally stable with any combination of source impedance ,load impedance , drive level , and supply voltage and achieving any reasonable gain , efficiency , bandwidth , and able to withstand about anything a customer can dream up at the same time is a real challenge . And what these source and load impedances are in band or well out of band have a strong bearing on stability. Then to add to the fun, if you are not a high quantity buyer of the semiconductors , and therefore cannot demand there be no changes in processing, you can do a design and a couple years later all of a sudden you have a stability problem that never existed because the vendor decided to make a process change such that the device still met the typical specs ,but had a much stronger propensity for half freq oscillations. Some process changes that raise low frequency gain without much effect on high frequency gain can make an amp have a tendency for low frequency oscillations because the decoupling /low frequency circuitry loading is now not sufficient to suppress that . Enough of that , what CAN be happening here is with certain cable lengths between the amp and the K3 , in band or out of band impedances presented to the K3 could well make the K3 PA want to have a spurious output like half frequency oscillation or low frequency oscillations . I do not recall if the KPA500 has any resistive broadband padding at the input in normal operation , I believe they say they switch in a 3 dB pad when extreme overdrive is applied. Resistive pads are a great way to limit in band or out of band impedance excursions - BUT you give up amp gain dB for dB. Same is true at the output of the amplifier -(or combinations of in and output) certain loads may make the amp more prone to a spurious output at half the driving frequency - even though the load may look like a perfect 50 ohms in band at the fundamental frequency . This is another joyous feature of semiconductor power amp designers get to experience whether bipolar or FET . The designer has to be careful what the out of band impedances of the output filters are - and just because you have a 1:1 SWR in band with your antenna , the out of band impedances can be darn near anything . As I recall , in this case , he had the same problem even into a dummy load on the output. So just as an experiment it might be interesting to see of a 3 dB resistive pad between the amp and the K3 made the whole thing totally independent of cable length. I am m not talking about cable loss , I am talking about limiting the possible impedance excursions especially out of band . Enough of this - I spent 30 years of my life designing and putting into production these beasts , I enjoy the fruits of the Elecraft designers efforts .have no interest whatever in doing that again. I like antennas much better they don't half f or oscillate at low frequencies- at least so far .

Well, this is surprising, to say the least. Inasmuch as it seems to have happened in several places. I normally don't post remarks of the "no-problem-here" sort but I don't think this has anything to do with RFI or inductance. Neither are ferrite chokes likely to solve the problem. My K3->KPA500 cable is only 65 cm (26") long (the only piece of RG58 in my setup) but nobody mentioned any distortion. BTW: Both the K3 AND the KPA500 are earthed (grounded, if you prefer) separately to a common earth... I mean: grounding point, as well as the (manual) tuner, the SteppIR controller, etc. If a longer cable can solve the problem, it's OK but the main question (the "WHY?") remains unanswered... Strange, indeed. 73 Richard - HB9ANM ______________________________________________________________ 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 pfizenmayer at q.com From dld at degeorge.org Wed Nov 19 17:52:05 2014 From: dld at degeorge.org (David DeGeorge) Date: Wed, 19 Nov 2014 17:52:05 -0500 Subject: [Elecraft] KX3 Voice Monitor In-Reply-To: References: Message-ID: <546D1F15.70307@degeorge.org> I am a new KX3 user also and have noticed that the monitor seems to have some sort of effect applied much like the audio effects (which I have turned off).

Wish you were next door and we could compare OTA, which is, admittedly probably the best way. But I will try KK7P?s suggestion to DVR a clip and then play it back (repeated below). I have no doubt that the KX3 produces superior audio, and I?m experimenting with that as I get to know the rig. I have learned also (by just using this list) that there are abundant opinions and preferences about audio quality and parameters (moderator just began laughing loudly). For me, my monitor using a Heil 5.1 Gold Elite in its broader mode (it has two two modes) sounded less crisp than OTA S9+ copy. So I?m experimenting with that mich and with the Elecraft MH3. Thanks for comparing notes. 73?s. David Ahrendts, KC0XT, LA KK7P, Lyle: "Note that the KX3 has a great tool for adjusting Tx EQ and CMP. Record your voice using the DVR, then play it back using MON. Adjust Tx EQ and CMP and play back the sample and you will be able to hear what your signal will sound like to the other station. Doing this "live" with a microphone is not nearly as effective due to bone conduction of your voice to your ears." > On Nov 19, 2014, at 2:52 PM, David DeGeorge wrote: > > I am a new KX3 user also and have noticed that the monitor seems to > have some sort of effect applied much like the audio effects (which I have turned off). > At first I thought that it might be RF in my headset but it persisted with the RF output > turned to 0 and the rig terminated in a dummy load.

This can wreak havoc with your CW side tone for example if you add an aftermarket audio DSP to a radio. Elecraft have obviously taken steps to make sure that the KX3 doesn't have an issue with CW sidetone, but in the case of voice where they are doing audio equalisation for example, they may be using some long FIR filters that introduce a bit of delay. Can't say I've really noticed, because I rarely use the KX3 on fone, and never with monitor on fone. 73, Matt VK2RQ > On 20 Nov 2014, at 12:37 pm, David DeGeorge wrote: > > Not so sure that I buy the bone conduction theory; I use the same headset with > my ICOM-7600 and its monitor, same head, same bones :-), but no effect.

The audio through bone conduction will be apparent in your ears before the audio from the monitor. The delay will not not be much, but it will give rise to a similar response (as you said) to the AFX delay response. 73, Don W3FPR On 11/19/2014 8:37 PM, David DeGeorge wrote: > Not so sure that I buy the bone conduction theory; I use the same headset with > my ICOM-7600 and its monitor, same head, same bones :-), but no effect.

Appreciate all of your input, Genuinely. But, I never had an ?issue of a delay? in response in the MON function. My issue was a ?muddy? audio response, i.e.: not sibilant enough for my taste, rather weighty at the bottom audio freqs but not balanced at the top, etc. And I wasn?t sure, being three-weeks into the KX3 as a newby, that I was actually hearing what my microphone was producing. A nice 10-minute session of DVRing helped tremendously and I did come up with EQ that I prefer ? to my ear: good presence, not muddy, pushed 2400 and 3200 gently. This is with the wonderful Heil MC5.1 Gold Elite which, I think already pushes the 2K mark some. Gonna do the same test for the fabulous Elecraft MH3 another day. My conclusion: MON is pretty darn close, but there is nothing like DVRing it and stepping aside to really listen objectively while you?ree not speaking. Best to you all and 73s.

As I said in the first reply, I guess I was having one of the old timers memory problems and forgot about looking on the Elecraft web site for the needed information! BUT, something very curious while connecting the cables. The first cable I connected went from a Toshiba laptop, running Win8. This is the setup where I had a problem with the Internet search not returning the needed driver, hence the request for help here and manual search. This morning, I hooked up the second cable to my home built PC, running Win7, and it took all of 10 seconds to go out on the Internet and find/install the needed driver. Very curious with the difference between Win8 and Win7 Internet search results!

I am using the popular SatPC32 software to track the birds and I have an azimuth steerable 5 element 2m Yagi which enables me to receive telemetry and the downlink side of QSOs when tracking birds which use a 2m downlink. This has wetted my appetite for full-on QSOs, and I am now the proud owner of a 70cm crossed Yagi which I plan to erect on my mast when weather permits. My problem is that all of my reading on what rig to use steers me towards Yaesu (and other Elecraft competitors) and never towards Elecraft. Ideally you need a duplex 2m/70cm rig with CAT tuning from the tracking software like SatPC32 to handle Doppler (when receiving things like FunCube telemetry I have to watch my P3 and manually tune my K3 and manually slew my rotator. Fine for reception, but probably not manageable on two bands for a QSO!) I do have an ft817 which is supported up-to-the-hilt by software and neat CAT interface boards (eg ARRL project kit) but I am stubborn and want to use my K3 with its superior specs, perhaps by adding an external KV432 transverter for 70cm. My question to the learned reflector brains trust is therefore:- Is anybody doing anything like this with their Elecraft rig? If so how do they overcome the apparent Yaesu bias in software etc? I guess Duplex isn't going to be possible but a neat simplex controller to switch bands for Tx/Rx probably is. Ray Coles, C.Eng.

For years I used my K3 and a Vista laptop with West Mountain USB converters. This setup worked perfectly. A laptop failure required me to upgrade. Due to the purchase of the new Win 8 laptop I needed to replace my USB RS232 adapters. I bought the WM cables for Win 8. Both of these cables failed while i was operating. They replaced them and then they failed again. I would guess they are extremely sensitive to RF. I should mention that these are used while operating portable.

Do you have the SSB module installed, and have set FL1 to OP1? In that case, when you switch from FL1 to FL2, you are changing from the crystal filter on the SSB module to the crystal filter on the main RF board. Maybe if there is a problem (eg bad solder joint, component in wrong place) on the SSB module, then maybe this is why you observe a difference in the volume? 73, Matt VK2RQ > On 21 Nov 2014, at 6:09 am, Eddy via Elecraft wrote: > > Greeting all to all the K2 wizards out there!

There are at least 2 different ways published by Elecraft for the filter settings. The K2 manual uses the default widths of 1.50, 0.70, 0.40, and 0.10 while the KSB2 manual indicates the use of the OP1 filter for CW FL1. Those filter widths are not graven in stone, the user is able to set most any filter width desired for his particular operating preferences. Since you have Spectrogram installed, you can measure the AF signal amplitude as well as the filter width and placement within the audio spectrum (just don't change the AF Gain during the comparison). Normally the amplitude through the filters is close to the same. If it varies substantially, you have a problem to locate and resolve. 73, Don W3FPR On 11/20/2014 2:09 PM, Eddy via Elecraft wrote: > Greeting all to all the K2 wizards out there!

I know this because I wanted to increase the volume in one ear and there is no balance control. One thing that "could" cause this is if CONFIG:SPKR+PH is turned to YES. There are variables that might affect this suggestion. Such as whether you are using the front or rear headphone jack and whether you have external speakers plugged in to the rear jack. 73, Mike K2MK Jeff Maass wrote > We have a new-to-us K3 at the PJ2T station (#00157).

This was particularly so for the I-phone OS. Some of the newer apps required the update, so I did it. It made a mess of just about everything else - enough so that I ditched the I-phone entirely and bought a Samsung Galaxy. Apple made it impossible to go back to the original OS, and numerous other functions slowed down (a few just stopped working as they once had.) The same happened with the latest OS X for desktops. On my charitable days I suspect the old hardware just doesn?t have the horsepower to run the new operating systems. On my cynical days I've wondered if it?s a marketing strategy - to sell new hardware. Today is a cynical day.

I agree, a separate SVGA display, with its higher resolution, and of course the added features over the P3 is the better solution. Unfortunately, I think there are many who are like me who do not want yet another big display in the shack. In my case, I have no room for one and if I did, I don't think I would put one in front of me. When I operate, I like the K3/P3 smack dab in front of me, not a screen. I am not anti-computer though -- having been a professional programmer for 47 years (now retired), I do have my Mac computers in my shack, one iMac-24 and my Macbook Pro laptop. The only ham radio related function that I use with these is running the Elecraft utility programs or maintaining my logbook in my own logging software written to my personal demanding & selfish tastes. I don't rely upon the decoding features very much but I admit that when I have friends in the shack, it is nice to be able to show them the text of the CW being received. Having this function on the P3 would be a nice added feature. If it were to require some extra hardware component that cost about the same as the SVGA P3 option then it would not bother me at all. 73, phil, K7PEH > On Nov 21, 2014, at 7:19 AM, Charlie T, K3ICH wrote: > > I have no recent experience with any of the digital modes, but I can tell you, the only time I even LOOK at the P3 is when I want to hit one of it's control buttons.

I subsequently sold both in favor of the K3 and KX3, respectively. Of course the K3 will not support duplex operation (only one DSP Rx). But I have not determined if one can operate split band between Rx and Tx. If so, probably sw can be developed to control VFO-A (Rx) separate from VFO-B (Tx). I use free sw (Trakbox from IK7EZN) to do that for eme in the same band but both Rx and Tx are not tuned by sw during operation. Another approach is using two radios. I have not tried it (yet) but using the KX3-2M on 145-MHz and my K3/432-xvtr on 435-MHz for full-duplex operation is an approach I am looking to do. You could combine using your FT-817/K3+KV432? I believe SatPC32 can control two radios to give you auto-tune/track. Perhaps we will hear from someone else whether dual-band split-freq works with the K3. 73, Ed - KL7UW -----------snip Ideally you need a duplex 2m/70cm rig with CAT tuning from the tracking software like SatPC32 to handle Doppler (when receiving things like FunCube telemetry I have to watch my P3 and manually tune my K3 and manually slew my rotator. Fine for reception, but probably not manageable on two bands for a QSO!) I do have an ft817 which is supported up-to-the-hilt by software and neat CAT interface boards (eg ARRL project kit) but I am stubborn and want to use my K3 with its superior specs, perhaps by adding an external KV432 transverter for 70cm. My question to the learned reflector brains trust is therefore:- Is anybody doing anything like this with their Elecraft rig? If so how do they overcome the apparent Yaesu bias in software etc? I guess Duplex isn't going to be possible but a neat simplex controller to switch bands for Tx/Rx probably is. Ray Coles, C.Eng.

They are ACCUMULATED peaks for a fairly long measuring period, so they show transient clicks and other forms of distortion far better than an averaged measurement. Indeed, I showed measurements of the KPA500 running at 500W out that have very low distortion (as indicated by occupied bandwidth). Yes, bandwidth (and distortion) increases at bit if the KPA500 is driven harder. As to peak and average power -- the measurements are of Peak Envelope Power, which for CW, RTTY, PSK31, and the WSJT modes is keydown power, and for all but CW, is the same as the Average Power. The average power is less on CW because of the spaces between elements. Crest Factor is relevant only on SSB. For normal speech, crest factors range between 10 and 20 dB. We often use compression to reduce that Crest Factor, and the K3 sounds very good when it is set for about 10 dB of compression on peaks. I haven't measured the resulting Crest factors, but long experience in pro audio suggests values of 6-10 dB would be the result. The KPA500 is quite well protected against conditions of overload. It will add resistive attenuation if overdriven by as little as a dB and/or into a poorly matched load, and will Fault if overdriven by a lot. Thus, it is probably not possible to drive a KPA500 deep into saturation. This is true regardless of the type of modulation in use (CW is modulation by a square wave). The highest power measurements I made of the KPA500 were at the level which more drive would have caused that resistive attenuation to be added. Indeed, the only way to reduce the Crest Factor with a KPA500 is to apply more compression to the driving signal. Note also that I showed measurements of the K3 driving a very good legal limit tube amp to its rated power, and the waveforms were nearly identical. That tube amp, a Titan 425, has no protection circuitry, only a red LED indicating excessive grid current. So -- the ONLY way in which my measurements show "better" numbers than an averaged measurement is that they use peak power as a reference, and applies ONLY to the SSB measurements. 73, Jim K9YC From matt.vk2rq at gmail.com Fri Nov 21 14:36:21 2014 From: matt.vk2rq at gmail.com (Matt VK2RQ) Date: Sat, 22 Nov 2014 06:36:21 +1100 Subject: [Elecraft] KX3 - SWR Display of "--" In-Reply-To: <5a9d170e.159d01.149d31ad34e.Webtop.54@optonline.net> References: <5a9d170e.159d01.149d31ad34e.Webtop.54@optonline.net> Message-ID: Above 10W of power, the KX3 will disable the internal KXAT3 ATU and rely on the amplifier to supply the SWR readings over the ACC1 cable.

The KXPA100's SWR bridge is on its LPF board, and is part of all KXPA100's, with or without the KXAT100 Antenna Tuner Option. The KX3 currently doesn't display the KXPA100's SWR, it instead displays the KX3 SWR measurement. When the KXPA100 is PA Bypassed (under about 10 watts), the KX3 SWR bridge sees the antenna impedance, so the SWR display is appropriate. However when the KXPA100 is not bypassed, the KX3 SWR display is of the input of the KXPA100. Wayne has on his KX3 firmware "todo" list a task to display KXPA100 SWR on the KX3 display when appropriate. The KX3 displays dashes when its power is too low for an accurate SWR measurement. The KXPA100's view of the antenna system SWR can be displayed with the KXPA100 Utility Operate Page, LEDs on an KXAT100-equipped KXPA100, or an external SWR meter like our W2. 73, Dick, K6KR -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Matt VK2RQ Sent: Friday, November 21, 2014 11:36 AM To: stan levandowski Cc: Elecraft Subject: Re: [Elecraft] KX3 - SWR Display of "--" Above 10W of power, the KX3 will disable the internal KXAT3 ATU and rely on the amplifier to supply the SWR readings over the ACC1 cable.

The KX3 SWR indication is used below 10 watts, but the KXPA100 indication is used above that level. It should go away if you increase (or decrease) the power a bit. It sounds as though you are operating right on that critical threshold. 73, Don W3FPR On 11/21/2014 11:06 AM, stan levandowski wrote: > I just got a KXPA100 yesterday.

On my side, I am a bit disappointed with my KX3-2m because of low TX output (2W instead of 3 announced) and lot of birdies on dummy load in RX mode. When using an external antenna, noise level increases and some birdies disappear but not all especially on 144.400 MHz. Do not try to connect an antenna (flexible quarter wave in my case) directly on SMA socket, you will receive a lot of birdies so, no way to use my KX3-2m like I used to do at the end of 70's with my IC-202 transceiver and telescopic antenna.

I'm wondering if I am tuning properly. Should I be tuning on the PX3 so that the frequency tuned is on the center of the PSK31 stream on the waterfall? Or something else? Auto spotting doesn't seem to help a lot. With really strong signals, it seems to decode fairly well, but I've been having trouble with the weaker signals.

Good idea, but it is not a RF feedback. It happens also with VOX=off (RF output power=0). With a audio record (e.g. Audacitiy or scope) of the sidetone you can see, that dot length is very unregular (set speed to 40 wpm). If you do the same on a HF band, each dot has the same lenght - perfect. On 2m CW is useful with low speeds only. On higher CW speeds the sidetone is very irritating for keying. tnx es 73, paul hb9axl From nf4l at comcast.net Sat Nov 22 07:08:14 2014 From: nf4l at comcast.net (Mike Reublin NF4L) Date: Sat, 22 Nov 2014 07:08:14 -0500 Subject: [Elecraft] K3+KPA500+Steppir or K3+Expert KFA+ Steppir ?

The SteppIRs follow the K3 precisely. It's totally transparent. Just remember to use protection so that you don't accidentally transmit high power when the antenna is tuning. Damage to the SteppIR EHU can result. Use the KPA500 aux cable keying interrupt from Elecraft and either get the tuning relay option for the SteppIR SDA 100 controller or purchase the N8LP tuning relay. Before the other posts start to fly, yes you can go without protection but the operative word here is "accidentally". Sh1t happens especially when you add a computer into the mix. Do you want to risk damaging the expensive SteppIR EHU or do you want to spend some money for protection. 73, Mike K2MK Elecraft mailing list wrote > GM/GA/GE, > The K3 question in connection with Steppir yagi(s). > Will Steppir yagi follow K3 in the same manner as it follows Icom rigs, > that is, one tunes the Icom rig and the Stepper exactly follows it or does > one need to transmit on K3 so the Steppir knows where to tune ?

I have a BigIR vertical and a two element SteppIR beam running HRD, N1MM, Writelog and am about to add LP-pan to the mix. Everything works together and does so very well.

My personal KX3-2M is only putting out 2 watts on SSB, too (like yours), while the one of a friend of mine even only 1.5 watts (all measured on a calibrated PEP meter). Both units put out the full 3 watts on CW & FM. The low SSB power out is reflected on the KX3's internal meter, too. It seems there are units that have the problem and some that don't. Wayne's supposed to work on the problem and it should be fixable by firmware, that's the last response I had from him 2 weeks ago (after we had done a few other checks the weeks before). Eagerly waiting for new beta software to try the fix overhere ... Concerning the birdies: Yes, there are a few. With a real antenna connected there are only 3 or 4 left that are audible stronger than s1 in the 144.0 to 144.5 MHz range, non of them stronger than s3. Yes, it would be great to have no birdies at all in the weak signal band but to be honest I do not know of any transceiver of the last 20 years (and I've tried a few) that has no birdies at all. We certainly have to accept a few compromises when putting so much technique into such a small package. Haven't tried connecting just a whip directly to the KX3 yet, always had a yagi connected as with the small power out you need every bit of antenna gain you can get anyway to make QSOs. ;-) Have you tried using a smal HB9CV or 2L yagi a few meters away?

TX output 2W: Do you apply enought supply voltage? Min 2.5W are specified with 13.8VDC supply. Birdies: Yes, it has quite a few. But for my use this is much less tragic than the CW trouble. Hope you will find a solution for your usage. Merci es 73, paul hb9axl ---------------------------- Sorry Paul, no answer to your problem with CW (not yet tried). On my side, I am a bit disappointed with my KX3-2m because of low TX output (2W instead of 3 announced) and lot of birdies on dummy load in RX mode. When using an external antenna, noise level increases and some birdies disappear but not all especially on 144.400 MHz. Do not try to connect an antenna (flexible quarter wave in my case) directly on SMA socket, you will receive a lot of birdies so, no way to use my KX3-2m like I used to do at the end of 70's with my IC-202 transceiver and telescopic antenna.

Got it on Amazon.com . Selling the SLUSB on eBay paid for the TASCAM unit. I have it connected to my 27? iMac and use it for PSK31, JT65, JT9, and an occasional RTTY QSO. No jumpers to fiddle with, no special cables - simple cables with RCA connectors. Couldn?t be happier with it.

Yes, the K3 can be set to remember drive power by band and mode. The KPA500 does not need a control line from the rig to change bands -- it detects the TX frequency with a dit or a tap on the mic. There is a control line, but I've never used it. The only control that is needed is PTT from the rig to the KPA500. There is a serial port. The only thing I use it for is to load firmware updates. 73, Jim K9YC From jim at audiosystemsgroup.com Sat Nov 22 12:52:42 2014 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 22 Nov 2014 09:52:42 -0800 Subject: [Elecraft] [Elecraft[ [K3] Sound card suggestions In-Reply-To: <01db01d00673$8e1f3540$aa5d9fc0$@gmail.com> References: <01db01d00673$8e1f3540$aa5d9fc0$@gmail.com> Message-ID: <5470CD6A.1060307@audiosystemsgroup.com> On Sat,11/22/2014 8:44 AM, Ian - Ham wrote: > So, my question is this - What else are people using as an external USB > sound card with their PCs and the K3?

Good idea, but it is not a RF feedback. It happens also with VOX=off (RF output power=0).

Thanks VK2RQ for the pointer. I tried it out while listening to the LZ contest on 15m today, tuning across the many contest stations in CW sounds so much better with VFO NR OFF compared to VFO NR ON, the latter causes a ?hickup? with audio going low at every strong signal I tune across. Band noise is high enough at the moment to mask the KX3 VFO tuning noise so no need to enable VFO NR. Still, I plan to do the tuning noise mod on the KXFL3 as soon as I can find some time to do it. 73, Wouter Jan PE4WJ On Wed, Nov 19, 2014 at 9:18 PM, Matt VK2RQ wrote: > Have you got VFO NR enabled?

I am considering the same antennas for my QTH and adding a second receiver to the K3. I find that I am RX limited compared to signal reports that I get that are not just the 59 contest mode. So for me this will be a significant investment with the receive system and extra receiver so I only want to do it once and want to be sure that I make the best choice I can. The only thing I know so far is that I have had personal interaction with persons who have used the K9AY and HI-Z and the HI-Z is consensus winner in this comparison.

In this release there have been a number of improvements to the panadapter display for the KX3 and LPPAN. In particular 1) A rework of the downsampling routines for the spectrum display has resulted in a much greater resolution than previously. 2) Addition of 24 bit audio mode 3) Customization of the look and feel of the spectrumscope http://va2fsq.com/?page_id=612 4) The CW - FSK-D - PSK terminal mode has been made more compact and now has a much larger type ahead buffer. Win4K3Suite is the most comprehensive radio control program available for the K-Line and the KX3.

Here, output power is the same using internal batteries or external 13.8V in FM or SSB; here, I can perform precise power measurements up to 24 GHz. Thanks in anticipation, Wayne, for power improvement to come.... May be that a future software release will manage to also improve rejection of birdies too. For the moment, I have just tried with an external antenna 3 elements Yagi antenna located a few meters from KX3 and it was the same situation regarding internal birdies. Interesting to know what is the behaviour of 4m module compared to the 2m one? 73's.

The old EMU0202 that everyone recommends isn't available any longer, and a search of eBay this morning turns up none being offered there at the moment. I have a SignaLink USB, which is currently configured for use with my FT-817 when I'm operating portable, and I don't want to have to reconfigure it every time I want to use a different rig. So, my question is this - What else are people using as an external USB sound card with their PCs and the K3? I have an HP desktop with Windows 7. The computer doesn't have room inside for another internal sound card due to other expansion boards I put into it. :) Thanks and 73, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik.ian at gmail.com 10-10 #74624, North Georgia Chapter #2038 K3# 281, P3 #688, KPA500 #1468 --- This email is free from viruses and malware because avast!

I get zero power output into a 50 ohm dummy load. As it is right now, it is built only as the 20/40 meter with no ATU installed (the base kit). I have run through the troubleshooting table and made sure: 1. R4 is fully clockwise (and there is a difference in level to a monitor KX3 nearby when this is adjusted). 2. J7 is jumped between pins 1 and 3 3. T1, L3, L1, and L2 are wound correctly and all have resistance of less than 1 ohm. When measuring the DC voltages across the transmitter: Q1 - (D) 13.85; (G) 0.31; (S) 1.61 Q4 - (E) 0.23; (B) 0.95 [with power out via the watt meter during measurement]; (C) 2.46 Q5 - (E) 3.71; (B) 2.45 [with power out during measurement]; (C) 13.85 Q6 - (C) 13.85 The Q5 emitter seems to be high with the other values close to those listed in the KX1 manual. I'm not sure what to make of the power out during the measurement other than a poor connection somewhere. I'll be contacting Elecraft for some help with the troubleshooting, but thought I'd ask the group in the mean time. Any suggestions would be appreciated.

When the K3 is in DATA A mode the mic gain will adjust the level for the line in so adjustment when using different programs is easy. level differences can be a problem with running multiple programs for digital as they seems to have different algorithms and different output levels I no longer use FLdigi and have moved to MMVARI as it has internal TX level adjustment that is independent of the soundcard level. with this I can match the output with the WSJT-X and MMSSTV. I can't seem to find this independent control for FLdigi. I have only tried Coacomodem some time ago but I believe it too has an independent level control that may help in matching levels with other programs although I cant remember if that setting is linked to the windows levels or not I don't believe that WSJT-X has this though.

I would suggest you check the soldering of R11 and R10 since those set the DC bias point for Q5. Also check the value and soldering of C41. That capacitor bypasses R10, so that for purposes of RF, only R11 is present in the Q5 emitter path. Do you have capability to measure the RF voltages at the various stages? An RF probe or an oscilloscope with a 10X probe will do fine. If so, let me know which and we can check the RF voltage at each stage to determine the point of failure. I know that is not detailed in the KX1 troubleshooting section, but I have 'normal' RF voltages for each stage of the KX1 transmit section, or I can verify with my testbench KX1. 73, Don W3FPR On 11/23/2014 6:35 PM, Scott Anderson wrote: > Hi all, > > I'm working on getting KX1 2846 up and running and have run into an issue > with the transmit testing.

At this drive level, I didn't bother to connect the ALC but the amp still has it's SWR etc. safety features enabled. It didn't like it when I had my 40M dipole selected and tried transmitting on 14 MHz.! The PW-1's are going for around $3k and DO have a decent antenna matcher inside. Admittedly, this makes for a much larger station package, but if you get a good deal on one, it might be an alternative. Especially if you also own a K3. That said, remember, if you're 20 over S-9 at a kilowatt, you'll still be S-5 at 100 milliwatts. 73, Charlie k3ICH From nw8l at whitemesa.com Mon Nov 24 11:14:38 2014 From: nw8l at whitemesa.com (Bob NW8L) Date: Mon, 24 Nov 2014 09:14:38 -0700 (MST) Subject: [Elecraft] K3 and FLDIGI Question In-Reply-To: <5472726F.7010705@nexicom.net> References: <74E8F226-89C1-4EB5-8E85-20E5E1870D8C@me.com> <5471ECB4.5090908@nexicom.net> <37994A37-AA94-482C-B095-35D0FB4A1C23@me.com> <54725C18.2080200@happyvalleybiz.com> <5472726F.7010705@nexicom.net> Message-ID: Fldigi has a TX level *attenuator* control on the status bar (to the left of the AFC button) that can be used to trim the TX level.

This is to match the output level so it matches other programs this adjustment is independent so it wont effect levels from other programs. If the output levels of all program can matched ie FLdigi WSJT-X, MMsstv, etc. it simplifies things when moving from one digital program to another by not having to readjust levels every time to achieve the proper setting of four bars fifth blinking. I think if you read the rest of the postings you will understand this need.

At least in the Windows world (Vista, Windows 7, Windows 8/8.1) that adjustment is handled in the Windows Sound Mixer. The "Master" control (hardware) for the output is set to 60 to 80%, the application specific outputs are maintained as separate sub-mixer levels and are generally left at 100% - 100% of the maximum set in the hardware - since application based controls are all relative in the hardware abstraction layer *unless* the particular application is designed to use the sound card in "*exclusive* modes ("Port Audio" is not exclusive). In any case, reducing the audio output of a Windows based digital application to control power output *will* run afoul of the ALC/power control in the K3 (and presumably the KX3). The "attenuator" in Fldigi (and any other digital software) should be left at 100% and the audio drive controlled by the K3 Line In control. 73, ...

From doug at ellmore.net Mon Nov 24 18:57:30 2014 From: doug at ellmore.net (Doug Ellmore) Date: Mon, 24 Nov 2014 18:57:30 -0500 Subject: [Elecraft] New Release of Win4K3/KX3 Suite Message-ID: First let me say, I am not an employee of Win4K Suite, but I just want to spread the word about a product that make that investment in your K3 and KX3 even more powerful and fun. I thought I pass on the word if you have not checked out the new release of the Win4K3/KX3 Suite (http://va2fsq.com/) and you have a KX3 or K3, you should. Version 1.708 has a number of significant improvements to the spectrum scope. One such improvement is a rework of the downsampling of DSP data for the display. My buddies and I gave Tom some feedback and showed him what we like in other panadapters. He took our suggests and did something with it. New routines now display many more peaks than previously and even many more than the NAP3 panadapter display. I use to be a beta tester for NAP3, and I have extremely impressed with Tom's development. It seems to be an incredibly stable software product. When I compared it side by side with NAP3, Win4K Suite found signals NAP3 did not see. There is flexibility to use either a 16 bit or 24 bit sound card. There are 32bit and 64bit releases, too. One of the things that is nice is the customization of the panadapter display. You can put in your band limits for your zone or license class, and define colors nicely. There were some refinements of the terminal window, too. I used the a pre-release during SS SSB with N1MM+ and both were very stable. During SS CW, I was able run CW Skimmer, CW Get, use the Terminal to capture long strings of the K3 decodse of CW, and run N1MM+. I've never been able to run on CW during a contest before. But with all that going, I was able to get long cw runs going day and night on 40m, rates twice as high as any of my previous search and pounce rates. Lots of fun. A big batch of LoTW confirmations afterwards towards 40m CW WAS, too! I use com0com with Win4K Suite for virtual com port support, then run HRD Logger application, and HRD Rotator (when not using N1MM+) with Win4K Suite. I no longer use HRD's Rig Control. Win4K suite replace HRD's Rig Control as the server HRD and other apps can connect to in order to access the K3/KX3. HRD Logger works extremely well with Win4k suite. click on a dx spot in HRD Logger or Win4K3 dx window, and the radio QSYs. Nice! With HRD Logger and Win4K cluster window open, you can be connected to two different DX Clusters like Club Log (synched with your DXCC Status) and HRD Logger (also synched with your DX status). Then using the spectrum you can look, listen and feel on the DX is working and where! Awesome. He has a nice split feature that allow you to click on split, then right click up 1, 3, 5 or 10. Quick and not mistakes sending on the DX station wanting to work split. Give it a try during CQ WW CW or chasing DX/WAS, I think you will be excited with the product. 73, Doug NA1DX From nw8l at whitemesa.com Mon Nov 24 20:53:53 2014 From: nw8l at whitemesa.com (Bob NW8L) Date: Mon, 24 Nov 2014 18:53:53 -0700 (MST) Subject: [Elecraft] K3 and FLDIGI Question In-Reply-To: <54735D74.3090107@subich.com> References: <74E8F226-89C1-4EB5-8E85-20E5E1870D8C@me.com> <5471ECB4.5090908@nexicom.net> <37994A37-AA94-482C-B095-35D0FB4A1C23@me.com> <54725C18.2080200@happyvalleybiz.com> <5472726F.7010705@nexicom.net> <54735D74.3090107@subich.com> Message-ID: Sigh. I don't see how you read that into my message. I am *not* advocating using the Fldigi attenuator to adjust transmit level in the K3. That ofcourse is done with the K3 power setting, with the K3 input control set for 4-5 bars ALC indicated. I'm saying only that the attenuator can be used to establish the level from flidigi to the soundcard, e.g. to equalize it (if possible) with the output of other programs so that the soundcard and K3 settings don't have to be touched when switching between them.

It took a few adjustments to get it to look like I wanted, but I finally did it. I run with a 192KHz, 24 bit card. Tom now supports 24 bit. It isn't a spectrum analyzer, but it sure does look good. I don't run with the total of software applications that Doug is running, but I use three monitors to display all that I do run. I use HRD for logging and spotting, CWSkimmer and FLDIGI or DM780 depending on circumstance. For contesting, I replace HRD with N1MM. What I have noticed is that running without the need to use LPBridge allows my software and computer to be less finicky. Overall, the switch to Win4K3 has been an improvement in what I can see and smoother operation. I would like to recommend that any KX3 owner who wants to really see what an integrated station operation can do start with installing Win4K3. 73, Barry K3NDM ----- Original Message ----- From: "Ellmore, Doug" To: "elecraft" Sent: Monday, November 24, 2014 6:57:30 PM Subject: [Elecraft] New Release of Win4K3/KX3 Suite First let me say, I am not an employee of Win4K Suite, but I just want to spread the word about a product that make that investment in your K3 and KX3 even more powerful and fun.

Of course that's wrong. But again, that's not what I said! I refer to the attenuator merely as an option to set the baseline fldigi output level. This would be a static setting, made in the program setup phase, with no need to touch it again. Rest assured, there are 4-5 bars ALC at all times on my K3 during digital operation, and if I want to change the power level I use the power control!

My understanding is that N1MM does not directly support sending the KY command to the rig's control interface. However, I found some hints about directly keying a KX3 without any additional interface by wrapping the "KY" command in N1MM's CATA1ASC command inside a function key macro. I have not checked in detail but my feeling is that KX3 and K2 use the same command structure for CW keying with the KY command. Will this approach work with a K2 as well? Will the "special serial cable" work with a serial to USB adapter? Has anyone tried this already?

I thought I pass on the word if you have not checked out the new release of the Win4K3/KX3 Suite (http://va2fsq.com/) and you have a KX3 or K3, you should. Version 1.708 has a number of significant improvements to the spectrum scope. One such improvement is a rework of the downsampling of DSP data for the display. My buddies and I gave Tom some feedback and showed him what we like in other panadapters. He took our suggests and did something with it. New routines now display many more peaks than previously and even many more than the NAP3 panadapter display. I use to be a beta tester for NAP3, and I have extremely impressed with Tom's development. It seems to be an incredibly stable software product. When I compared it side by side with NAP3, Win4K Suite found signals NAP3 did not see. There is flexibility to use either a 16 bit or 24 bit sound card. There are 32bit and 64bit releases, too. One of the things that is nice is the customization of the panadapter display. You can put in your band limits for your zone or license class, and define colors nicely. There were some refinements of the terminal window, too. I used the a pre-release during SS SSB with N1MM+ and both were very stable. During SS CW, I was able run CW Skimmer, CW Get, use the Terminal to capture long strings of the K3 decodse of CW, and run N1MM+. I've never been able to run on CW during a contest before. But with all that going, I was able to get long cw runs going day and night on 40m, rates twice as high as any of my previous search and pounce rates. Lots of fun. A big batch of LoTW confirmations afterwards towards 40m CW WAS, too! I use com0com with Win4K Suite for virtual com port support, then run HRD Logger application, and HRD Rotator (when not using N1MM+) with Win4K Suite. I no longer use HRD's Rig Control. Win4K suite replace HRD's Rig Control as the server HRD and other apps can connect to in order to access the K3/KX3. HRD Logger works extremely well with Win4k suite. click on a dx spot in HRD Logger or Win4K3 dx window, and the radio QSYs. Nice! With HRD Logger and Win4K cluster window open, you can be connected to two different DX Clusters like Club Log (synched with your DXCC Status) and HRD Logger (also synched with your DX status). Then using the spectrum you can look, listen and feel on the DX is working and where! Awesome. He has a nice split feature that allow you to click on split, then right click up 1, 3, 5 or 10. Quick and not mistakes sending on the DX station wanting to work split. Give it a try during CQ WW CW or chasing DX/WAS, I think you will be excited with the product. 73, Doug NA1DX ______________________________________________________________ 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 w4ccs at w4ccs.com From w3fpr at embarqmail.com Tue Nov 25 08:07:10 2014 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 25 Nov 2014 08:07:10 -0500 Subject: [Elecraft] K2 plus N1MM logger in CW In-Reply-To: <1416918273682-7595061.post@n2.nabble.com> References: <1416918273682-7595061.post@n2.nabble.com> Message-ID: <54747EFE.5000508@embarqmail.com> Ralf, I cannot answer your N1MM question, but I can answer with certainty about the K2 'special cable' - Yes, the 'computer' end of that cable can be plugged into a USB to serial adapter. Just do *not* plug the adapter directly into the K2 AUX IO connector. You may find some USB to serial adapters that will not work well at the slower 4800 baud rate used by the K2. Try to find one with an FTDI chipset. 73, Don W3FPR On 11/25/2014 7:24 AM, DL6OAP wrote: > Will the "special serial cable" work with a serial to USB adapter? > > From paulbousquet at icloud.com Tue Nov 25 10:36:36 2014 From: paulbousquet at icloud.com (Paul Bousquet) Date: Tue, 25 Nov 2014 10:36:36 -0500 Subject: [Elecraft] GND Connection Between KX3 & KXPA100 Message-ID: <95C72E45-E1E0-4567-A526-EF434E302ED1@icloud.com> Just wondering how important it is to have connect the GND terminals between the KX3 and the KXPA100 amp.

I am aware of the approach that keys the K2 with the one transistor-circuit using the CTS/DTS control line, but will be running a small netbook under WindowsXP - mainly because this computer produces less rf noise than my other two - so I am not sure if I will have the latency issue or not. I always liked the Winkeyer solution more (I have a Microkeyer interface, but no cable for linking the MK to the K2) But it is worth trying. When I got the K2, I used the parallel port of my old laptop (with CT software, I think) with a similar one-transistor circuit for keying, but was not completely satisfied - using this K2remote tool from the Elecraft webpage (using the "KY method"), the keying sounded much better to me. In my understanding, sending just the textstrings to the KIO-interface and let the K2 form the dots and dashes should be closest to the Winkeyer solution, and would only use ressources that I already have. I think I will test the macros on the KX3 first and then try my USB-serial adapter with the K2 (the adapter works with a rather old Garmin Geko handheld GPS, am not sure about the Baud-rate, but I think it also is at 4800). If this is not working, I will try the "CTS/DTS method"...

In fact bonding everything in the station together with heavy wire or braid can cure many "strange happenings". Other than that, you are correct that there is no need from a signalling connection standpoint to bond the KX3 to the KXPA100. Bonding the station equipment together and to a station ground point is to keep all the gear at the same potential and can assist with such things as extraneous noise pickup, stray RF and other electrical annoyances. While on the subject of grounding, remember that NEC code requires that all ground rods and wires be connected back to the utility ground rod with heavy gauge wire (#6 or larger). This is a safety consideration and has nothing to do with the proper functioning of your equipment. 73, Don W3FPR PS: Your first post is just fine.

The issue is how N1MM sends CW on the serial port, which can get choppy when it is interrupted by other software running on your computer. WinKey is a very good way to send CW from a computer. It works quite well for me. At low speeds, and under the "right" conditions on the computer, you can send CW on the DTR pin of the serial port. It even works with USB to RS232 adapters. You need a simple transistor inverter to convert the keying signal to a short between the keying line and the chassis. Collector to keying line, emitter to chassis, DTR through 4.7K to the base. 73, Jim K9YC From k6dgw at foothill.net Tue Nov 25 12:34:22 2014 From: k6dgw at foothill.net (Fred Jensen) Date: Tue, 25 Nov 2014 09:34:22 -0800 Subject: [Elecraft] K2 plus N1MM logger in CW In-Reply-To: <1416918273682-7595061.post@n2.nabble.com> References: <1416918273682-7595061.post@n2.nabble.com> Message-ID: <5474BD9E.7020301@foothill.net> On 11/25/2014 4:24 AM, DL6OAP wrote: > However, I found some hints about directly keying a KX3 without any > additional interface by wrapping the "KY" command in N1MM's CATA1ASC command > inside a function key macro.

You can use the CATA1ASC command in any N1MM function key macro to send commands ... any commands you want. For SS SSB, I record my CQ and exchange in the K3 DVK memory and then use the function keys to send SWTxx commands to emulate tapping the M1 or M2 keys. > > Will this approach work with a K2 as well?

Be aware however that the 9-pin D connector on the back of the K2 is *NOT* an RS-232 serial port. 3 pins [Gnd, RX data, and TX data] are RS-232 levels. The other pins are not.

Dig out the KPA100 manual and look at page 48. Do the SWR Bridge Null Adjustment first. Then do the Power Calibration. There may be some variability in the calibration from band to band because the diode response is not entirely linear with respect to frequency, but if you do the calibration on 40 meters or 30 meters, it should be quite reasonable for all bands. 73, Don W3FPR On 11/25/2014 12:55 PM, W8OV wrote: > I recently acquired a very clean K2/100 with external KAT100 ATU.

If one is using the Windows operating system, YOU MUST GO INTO THE OPERATING SYSTEM AND TURN OFF WINDOWS GENERATED SOUNDS!! For about the 30th time, the reason for that is because when Windows generates its internal sounds, the CPU first SHUTS OFF THE I/O PORTS, generates the operating system sounds, then turns the I/O ports ON again; and that is why Windows generated CW 'stutters'. Shut off the Windows sounds generation and the CW output will be as clean and stutter free as any external purchased CW generator. 73, Tom - W4BQF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Tuesday, November 25, 2014 12:29 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K2 plus N1MM logger in CW On Tue,11/25/2014 9:09 AM, Byron Servies wrote: > My K2 sounds great to me, as the operator, when using a paddle.

While a single point star grounding system may be best from an EMC point of view, it is not the best for noise reduction and 'sneak paths' in the gear we deal with in a ham station. In fact the multiple paths to that single point ground can create currents in the grounding system giving rise to noise in the gear that we are trying to reduce the noise. Review Jim's presentation on grounding in entirety. Jim does speak from many years of experience dealing with noise and sneak paths in professional audio installations, and I respect his opinions based on his years of experience dealing with these issues. If you have no ground current induced noise and are only striving for a lightning protection grounding scheme, then yes, the single point grounding system is the way to go, but that is not the situation in the modern ham station where we have to deal with audio and digital paths to/from computers, interface devices, ancillary gear and "who knows what" to the transceiver. Bonding all equipment together (with a mind to the path for the audio and RF) will minimize the extraneous noise currents on the shields between the boxes in the shack which will reduce the noise level in the receiver. I too have years of experience with design and testing for EMC considerations, and as I have indicated, each method of grounding has its place, but we are not dealing with EMC considerations alone. 73, Don W3FPR On 11/25/2014 5:46 PM, Eric Buggee wrote: > Hi all, > > One additional comment regarding grounding for RF interference, > extraneous noise & elecrical safety considerations is that the > preferred method for grounding should be: > > Single point grounding, ie all rig & amplifier ground connections > should be taken from a single point, (shack grounding buss). > > Relying on "daisy chain" grounding for example: through coax > cable(s) & their connectors; Rig > Amp > tuner > tground point can be > the source of intermittent RFI & distortion > > problems that can be difficult to nail.

What am I missing?. -- Dick - K4XU ______________________________________________________________ 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 bill at wjschmidt.com From n6kr at elecraft.com Wed Nov 26 00:36:58 2014 From: n6kr at elecraft.com (Wayne Burdick) Date: Tue, 25 Nov 2014 21:36:58 -0800 Subject: [Elecraft] K3 Timekeeping In-Reply-To: <398f3734-4cae-4fd0-9943-244d443b0d42@me.com> References: <398f3734-4cae-4fd0-9943-244d443b0d42@me.com> Message-ID: This is an unusual amount of error; it's typically more like +/- 1 or 2 seconds/day.

I updated N1MM logger to the most recent version, re-edited the macros in the manner described by K4MTX in his blog (who did it for the KX3) and it seems to work with the K2 as well. There seems to be enough space in the connectors of the "pseudo-serial" cable for the one-transistor keying circuit, so I will add it to the cable later and see how well this works - with the system sounds off. I hope, I have the date right - happy Thanksgving!

This is not quite as bad as Arlen's clock, but it is still annoying. I run quite a few skeds and nets and I like to be spot on time. Dear Wayne, are you listening? We need your help to write a little routine that goes like this:- When the K3 powers up, it reads an eeprom location which stores the last turn-on time. It calculates how long ago that was from the present time. It reads the correction factor in tenths of seconds per 24 hours from another eeprom location. It calculates the correction required in tenths of a second and updates the clock accordingly. It stores the tenths of seconds remainder in another location ready to be taken into account in the next calculation. Finally it updates the last turn-on time. Of course you will realize that an extra menu item will also be needed, so users can enter their clock correction factor. A single byte can store a correction factor from -12.7 to +12.7 seconds per 24 hours. With this software addition, the K3 will become a superb chronometer. Perhaps once a year the user will need to tweak the correction factor to allow for crystal aging in the real-time clock. 73 Roger, VK4YB From eric at elecraft.com Wed Nov 26 18:02:31 2014 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Wed, 26 Nov 2014 15:02:31 -0800 Subject: [Elecraft] K3 Timekeeping In-Reply-To: <4643D0CC-0D27-46AA-B75E-17CBCC932364@mac.com> References: <398f3734-4cae-4fd0-9943-244d443b0d42@me.com> <547653AA.6050508@elecraft.com> <4643D0CC-0D27-46AA-B75E-17CBCC932364@mac.com> Message-ID: <54765C07.1030908@elecraft.com> Not that I can think of.

Then drop down to Latency Timer and set that to 1ms.

Pick a 'time standard' that is appropriate for you - Cellphone time or Atomic clock as your time for skeds (those are quite accurate) as well as the time standard from WWV. The K3 clock can be reserved for those times when access to those other time standard sources are not available (such as Field Day and other similar occasions). The K3 RTC depends on the crystal and the associated capacitors. It is not a precision device, but is more than sufficient for logging purposes for outings where it is the main source of time stamping - assuming it is set correct at the beginning of the outing. My Timex watch seems to be quite accurate - I have not had to reset it in the last 3 months! In other words, I would not depend on the clock in the K3, KX3 or the K2 to be more accurate than my Timex. The need for time precision to the second is overrated IMHO - logging QSOs to the nearest minute seems to be acceptable, accuracy to the second is not required for logging purposes. 73, Don W3FPR On 11/26/2014 6:01 PM, Roger Crofts wrote: > My K3 clock loses about 9 seconds per day.

Thanks Pete. I'm using real hardware serial ports, usually provided by a Quatech 2-port PCMCIA adapter that I've used for nearly 10 years.

Unless things have changed in clock design in the past 2 or 3 years, "WWVB" clocks don't sync here. I suspect not enough signal in a ground-floor frame building even on the wall facing south. I have investigated an ethernet-synced digital wall clock and they aren't cheap by any means, well into three figures for a single-color one displaying HH:MM:SS readable across the room. My dream would be one with normal yellow color that turned red during the 15-18 minute and 45-48 minute parts of each hour and green during the 0-3 minute and 30-33 minute parts of each hour. Any old shipboard brass pounders will recall why! :) 73 de K2ASP - Phil Kane T2-00000208 Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From ormandj at corenode.com Wed Nov 26 19:53:35 2014 From: ormandj at corenode.com (David Orman) Date: Wed, 26 Nov 2014 18:53:35 -0600 Subject: [Elecraft] K3 Timekeeping In-Reply-To: References: <398f3734-4cae-4fd0-9943-244d443b0d42@me.com> Message-ID: I'm feeling lucky (quite rare). My KX3 (just checked) was ~20s off my NTP synced computers, and I set it about 3 months ago. I suppose it will drift more over time, but it sounds like there is variance that exists between units. How much do these clocks change over time in terms of cycles/accuracy? I'm not familiar with crystal based clocks and their operation by any means, hence the question, as reading some responses it sounds like it will change.

You *should* see: 1. The carrier 2. The 100 Hz subcarrier around it that carries the IRIG-H time code 3. The pair of tone sidebands [if the tone is on]. What you *will* see depends on which WWV you're tuned to. If it's 2.5 or 20 MHz, the above pretty well describes the display. If it's 5, 10, or 15 MHz, you will see: 1. The carrier 2. The 100 Hz IRIG-H subcarrier 3. The pair of tone sidebands 4. The second and third harmonics of the tones, maybe the fourth harmonic depending on conditions and strength of the signal at your QTH 5. The 100 Hz IRIG-H subcarrier around the pair of tone sidebands and all the harmonics. There is a single combined baseband that feeds all transmitters. Apparently, the 2.5 and 20 MHz transmitters are low level modulated with linear amplification. The other three appear to be plate modulated class C PA's right out of the hamshacks of the 50's. The difference is striking and surprising. I've always thought NIST was the Gold Standard. With a single tone modulating my K3 in AM, I see the carrier, the two sidebands, and essentially nothing else on a spectrum analyzer. I sent screen shots and an explanation to WWV, and asked them about the transmitters. The reply said, "We're pretty sure we're on frequency." I have an extra Hamstack Microchip 18F46K22 CPU here looking for a project. Maybe an outboard WWV [or WWVB] timecode demodulator that sets the K3 time [I assume that's possible via serial commands, didn't look]. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 11/26/2014 4:15 PM, Phil Wheeler wrote: > My watch is a Casio Pathfinder (barometer, altimeter, compass, and even > keeps time!).

It used the mains frequency for time keeping so the long term accuracy was good. Recently it became faulty and I could not get a replacement chip, so I decided to build something similar but more modern. (I do have a clock that is synchronised to 60KHz MSF but it is local time only, not UTC). I wanted something that would just give me auto setting, choice of UTC or Local time with auto DST. A bit of overkill for a 4 digit shack clock, but I used an Arduino, a GPS module, and an IR controller to switch modes etc. I did try it without the GPS conditioning but the RTC I had was very poor and even with calibration routines was less accurate than my old mains frequency clock, so I went for GPS which gave me auto setting as well. Nobody in their right mind would probably want to duplicate it, but anyway I put the details on: http://sourceforge.net/projects/arduinoledgpsclock/ Still to put it all in a box, but it works great. Full disclosure: I am a time nut! ;-) 73 David Anderson GM4JJJ > On 27 Nov 2014, at 00:25, Bob wrote: > > I built my own 24 hr dual zone station clock.

It is quite accurate - I check it against WWV about once a month and it has never been off by more than 2 seconds. I replace it when the battery dies or the plating on the edges of the back wears off. My Seiko sits in the drawer and shows the correct time twice a day:-) .

The rummer is that as analog watches age, the lubricants evap/deteriorate causing greater strain on the "motor" and that is why batteries don't last in older watches compared to newer.

The tones [500 and 600 Hz on alternate minutes] are transmitted at 50% modulation. The second harmonic of the tone on 10 MHz is about 15 to 18 dB below the fundamental tone on my P3 using the dBm scale. There is selective fading visible on the tones. The third harmonic is roughly another 15 dB below the second harmonic, and it fades more. At times, I can discern the fourth harmonic on the waterfall in monochrome mode, but can't see it on the spectrum display. The tone fundamental and each of the harmonics are surrounded by the sidebands of the 100 Hz sub-carrier and the IRIG-H time code. The striking part for me is the difference between 2.5/20 MHz and the other three. 2.5/20 are very clean, no tone harmonics, and the 100 Hz sub-carrier is where it should be and nowhere else. > > When I've listened to WWV (not often), I hear distortion. They're a > Standard for Frequency and Time, not high futility. :) The modulation that is generated at Ft. Collins [tones, ticks, time announcements] appears to be very high quality and exact. The weather, GPS status, and propagation announcements seem to come from other places and are of highly variable quality, mostly unintelligible for me. The WWV time announcements are rumored to be the voice of San Francisco area radio announcer. This may be an urban legend however. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From gm4jjj at yahoo.co.uk Thu Nov 27 15:36:28 2014 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Thu, 27 Nov 2014 20:36:28 +0000 Subject: [Elecraft] OT: K3 timekeeping In-Reply-To: <5476762D.2050803@foothill.net> References: <7FBA01A77AB64B809884E3A28D0CDDC6@ROGERN> <54766824.2020305@embarqmail.com> <54766D3A.7050002@socal.rr.com> <5476762D.2050803@foothill.net> Message-ID: <2975BA7F-77FF-447A-81B2-9A6F34742CF2@yahoo.co.uk> > I sent screen shots and an explanation to WWV, and asked them about the transmitters.

A receiver is not a watch! The main difference is quantity of the precision crystals required to maintain a few seconds per month accuracy that can be purchased. Timex can easily purchase them at a low price based on an order of 10,000 or 100,000 or even 1 million. Elecraft could only swing a deal on a purchase quantity of 100 or 1000. The quantity pricing difference is extreme. The K2, K3, KX3 are known for having fine receivers, that does not mean they are also precision timepieces. The RTC is meant to be an aid to logging when no other means is available. When working in the home shack, use computer time or some "Atomic Clock" to provide you with accurate time. When operating portable, set the Elecraft clock to the correct time before your outing. It will be sufficiently accurate for logging purposes over the weekend event or even the weeklong event. Remember "logging accuracy" rather than precise time to the nanosecond. Alternately, wear your Timex (or whatever) and ignore the Elecraft gear clock. If I want to know the time, I instinctively look at my wrist, it is a habit developed over many years. It is much quicker and more reliable than dialing up the time on any of my radios. 73, Don W3FPR On 11/27/2014 4:58 PM, Barry wrote: > Don Wilhelm-4 wrote >> The K3 RTC depends on the crystal and the associated capacitors.

First clock crystals of the variety used in the K3 are dollar items in qualities of one. I have bought them in 1000 piece quantities for 50 cents. They are available from many vendors. Second the K3 design places a 33pf capacitor (C60) on the high side of the crystal to ground. However the clock chip manufacturer (see the data sheet at http://www.nxp.com/documents/data_sheet/PCF8563.pdf) suggests a 5 to 25pf NPO variable at this node. They also specify a maximum of 25pf on the node so the 33pf fixed value is actually out of spec. Furthermore if the 33pf cap is not NPO or COG grade it will have a poor temperature coefficient. This could easily explain the wide range of accuracy seen by users. I would hope that Elecraft would offer a 5-25 NPO trimmer upgrade. When, properly trimmed, we should be able to get the same accuracy as that $10 watch. 73, Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Thursday, November 27, 2014 2:33 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] re K3 timekeeping Because the Elecraft receiver is not designed to sync with those multiple time signals, it is only capable of receiving them, and you can use them to sync the time with the Elecraft RTC. A receiver is not a watch! The main difference is quantity of the precision crystals required to maintain a few seconds per month accuracy that can be purchased. Timex can easily purchase them at a low price based on an order of 10,000 or 100,000 or even 1 million. Elecraft could only swing a deal on a purchase quantity of 100 or 1000. The quantity pricing difference is extreme. The K2, K3, KX3 are known for having fine receivers, that does not mean they are also precision timepieces. The RTC is meant to be an aid to logging when no other means is available. When working in the home shack, use computer time or some "Atomic Clock" to provide you with accurate time. When operating portable, set the Elecraft clock to the correct time before your outing. It will be sufficiently accurate for logging purposes over the weekend event or even the weeklong event. Remember "logging accuracy" rather than precise time to the nanosecond. Alternately, wear your Timex (or whatever) and ignore the Elecraft gear clock. If I want to know the time, I instinctively look at my wrist, it is a habit developed over many years. It is much quicker and more reliable than dialing up the time on any of my radios. 73, Don W3FPR On 11/27/2014 4:58 PM, Barry wrote: > Don Wilhelm-4 wrote >> The K3 RTC depends on the crystal and the associated capacitors.

I would add that the watch is really poor at RX and TX but you aren't complaining about that. The K3 does *not* have continuous background access to time signals independent of VFO frequencies, unless firmware and circuity is added to do so. Then it's a marketing decision whether there would be enough K3 owners who would pay the extra money for a K3 precision internal clock board that for most duplicates multiple devices in the shack. If you are using N1MM to log contacts, it is looking to the *computer* to supply time/date for contacts. If I were paper logging, I'd be looking to my wrist watch for the time. Why do I want to spend money to put a clock in a K3? I wouldn't buy the board. Myself, I wouldn't have put the clock in the K3 in the first place, just to prevent threads like this one. Now if I could get my K3 to make me fresh coffee during the contests, that might be interesting. How come the K3 doesn't make coffee? Isn't it just a little too easy to spend someone else's time and money? 73, Guy K2AV From david at g4dmp.fsnet.co.uk Fri Nov 28 05:41:34 2014 From: david at g4dmp.fsnet.co.uk (David G4DMP) Date: Fri, 28 Nov 2014 10:41:34 +0000 Subject: [Elecraft] [KX3] Backlight while charging In-Reply-To: <0396E3E3-8A77-4CF9-8990-7FEE8088B63A@gmail.com> References: <0396E3E3-8A77-4CF9-8990-7FEE8088B63A@gmail.com> Message-ID: <2CvLJpCeFFeUFwtn@g4dmp.fsnet.co.uk> Ah, at last some else sees my point of view, Seth.

From some of the comments above, it's not expensive nor difficult to implement. Firmware could be implemented to simply update the time when the radio is turned on, similar to the way Windows does periodic internet time updates for a similarly inaccurate timekeeper. We can always hope and ask for more. No harm in that. It's nice that Elecraft is so responsive to our many requests, unlike KIY. Thinking back 10 years, I never thought I'd own another American-made radio, after my Drake line. And I'm soon to own my first American car in 30 years, as well.

Virtually painless install that took all of 35 minutes and another 20 or so to finish reading the instructions and get it configured properly. Quick check on the local 2M repeater has it working on FM just fine with the repeater though I got reports of my TX audio being light and I did have to reconfigure the deviation as our local machine wants to see 4.5KHz instead of the default 3.5. I don't have a horizontal beam up for 2 meters yet (should be here next week some time) so I haven't checked the other modes yet. Right now the batteries are charging so I can haul it to our ham radio breakfast in the morning for a "show and tell" demo. The received audio sounds pretty distorted though. Almost as the RX is off frequency but tuning around while someone was transmitting didn't offer much change. This may be due to the way the DSP demodulates FM, not sure. Maybe Wayne will chime in after the holiday with an answer to this. Our repeater does have 5.0 KHz output deviation and isn't narrowbanded like many of the newer ones are so this might be the problem. There are a ton of repeaters here in KS and the surrounding states that still use the old standard of 4.5 KHz deviation so this could be a potential problem around here. However, I didn't get the transverter to operate FM repeaters with anyway so it's not really a complaint, merely an observation. All in all, it was extremely easy to install and configure but you DO need to read the manual and follow the instructions explicitly, especially when it comes to those super miniature coax cables for the local oscillator and antenna connections. A GOOD magnifier sure helps get those connections right - LOL.

After the recent reflector postings about WWV / WWVB I thought I would get first-hand recent information from him. The GPS satellites all carry on-board cesium standards that are synchronized with NTIS, and because of changes (below) to WWVB, cell phones remain the most accurate source of time for most of us. All the HF transmitters at Ft. Collins are the same TMC units that were put in service when the facility was built. The 2.5 and 20 MHz transmitters run at lower power due to propagation considerations. The time and other station-related voice info is sourced on site in Ft. Collins, and the various propagation and weather info comes from various "dial in" land-line sources. Hence the widely varying quality of these announcements. I forgot to ask about the individual who made the voice recordings ... Here's the most important info .... as of about a year ago the modulation scheme on WWVB (60 kHz) was changed (phase reversal each minute) and this has rendered most of the end-user equipment inoperative. Most (all ?) tracking receivers like the HP-117's are now useless without extensive modification. Most of the "atomic" clocks now in use ->do not<- synch to the current modulation scheme on the 60 kHz signal. This will explain the differences in displayed time on supposedly identical clocks and how some appear to not be getting sufficient enough signal to synchronize. He offered no comment on how to locate "consumer" clocks that -do- respond to the "new" modulation scheme. The 60 kHz transmitter is indeed an ex-LORAN C unit, and because of the higher power of the "new" transmitter the antenna system was rebuilt using material from the LORAN C site. The 20 kHz transmitter was "home made" by NBS staff at the old Beltsville, MD facility and moved to Ft. Collins. There is no longer an antenna for this transmitter and it will not return to the air. Trivia: The antenna was of such high-Q that a near-by thunderstorm system would often detune the system and cause the overload protection to trip the transmitter off. He suggests that a visit to the NBS website would be "informative". 73 Ken Kopp - K0PP From tomb18 at videotron.ca Fri Nov 28 15:41:49 2014 From: tomb18 at videotron.ca (Tom Blahovici) Date: Fri, 28 Nov 2014 15:41:49 -0500 Subject: [Elecraft] OT: Changes at WWV, WWVB Message-ID: <0NFR00MJEO5PW820@VL-VM-MR002.ip.videotron.ca> Hi interesting.

IIRC, the rubidium standards are much smaller and lighter and much more suited to satellite use. At one time I used a cesium standard to troubleshoot a timing issue when clocking the phone network. I think it, in its shipping container, weighed about 75#. The container probably weighed less than 15#. A cesium standard is fairly heavy. We had to lug it up to the 3rd floor of one central office. But the rubidium standards in the satellites are synced to the earth mounted cesium standards each day. And rubidium standards actually have better short term stability than do cesium standards. At least that is what I was taught in the various timing classes I attended. 73 de dave ab9ca/4 On 11/28/14 2:18 PM, Ken G Kopp wrote: > I have a long-time close friend who's retired from > the NBS in Boulder and was the project engineer > on the NBS #7 cesium standard.

But after more than four decades of being beaten to a pulp in systems design and programming for installs, hardware, planning systems, and statistical systems running on everything from mainframes to PC's: If it looks simple, it isn't. If you think you understand, you don't. If it looks really complicated, and you are convinced that it contains some awful problem beyond your current skill set, it's probably twice as complicated as it looks. But at least you are on the same planet as reality. The actual cost and time to provide actual fully debugged software is almost always more than the developing company can afford. Perfect code is never profitable. Nature could give a rat's a** whether her laws and behavior can be programmed with short, sweet, inexpensive code. She does not care whether you can feed your family on a programmer's salary. This is why hardware is such a b*tch to code for. She doesn't like you, and would just as soon smack you down. As soon as you fix one bug, the customer will find another and complain all the louder. Over a lifetime, programmers don't even get a percent of the praise they deserve. Software and firmware are reserved by the human race as a default container to receive complaints. Anyone who does not complain about software and firmware is presumed mentally deficient. Software and firmware that work perfectly are resented, never acknowledged and presumed programmed by snooty people that look down their noses at regular folk. The human race is completely confused by the idea that an SMT chip 1/2 inch by 1/2 inch could contain firmware that cost 500 bux to make in one afternoon by a single programmer, or could contain firmware that cost billions of dollars and tens of thousands of employees to develop over decades, and the only visual clue is a different unreadable number printed on the chip surface. Hams in particular will expect to pay the former price for the latter content, based on the size of the chip. This vein goes on for miles and miles, but you get the drift. 73, Guy K2AV From jmlowman at sbcglobal.net Fri Nov 28 17:28:59 2014 From: jmlowman at sbcglobal.net (Jim Lowman) Date: Fri, 28 Nov 2014 14:28:59 -0800 Subject: [Elecraft] Heil mic/headset for use with K3/KX3?

OMEGA was on 10 - 14 or so KHz. There was a LORAN-C station in Gillette WY, maybe WWVB came from there. I would imagine converting a 100 KHz transmitter to 60 KHz is a whole lot easier than 10 KHz to 60 KHz. Near the end of the LORAN-C era, some of the transmitters were replaced by "Accufix" transmitters by MegaPulse Corp. No oscillator(s) or amplifier(s), no tubes, basically harked back to spark ... except they used SCR's instead of a spark gap. They also had a roomful of high-tech timing equipment, and produced exact LORAN-C pulses at a megawatt or so. I doubt WWVB is using one of those. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org >> On Nov 28, 2014, at 1:54 PM, Ken G Kopp wrote: >> >> Hi Roger! >> >> Yes, you're not the first to spot my error about ND, and my friend is >> trying to confirm where the WWVB >> LORAN C transmitter came from From htodd at twofifty.com Fri Nov 28 18:40:41 2014 From: htodd at twofifty.com (Hisashi T Fujinaka) Date: Fri, 28 Nov 2014 15:40:41 -0800 (PST) Subject: [Elecraft] OT: Changes at WWV, WWVB In-Reply-To: References: Message-ID: On Fri, 28 Nov 2014, Ken G Kopp wrote: ... > Here's the most important info .... as of about a year > ago the modulation scheme on WWVB (60 kHz) was > changed (phase reversal each minute) and this has > rendered most of the end-user equipment inoperative. > Most (all ?) tracking receivers like the HP-117's are > now useless without extensive modification. > > Most of the "atomic" clocks now in use ->do not<- synch > to the current modulation scheme on the 60 kHz signal. > This will explain the differences in displayed time on > supposedly identical clocks and how some appear to > not be getting sufficient enough signal to synchronize. I heard from my time-nerd friends that the modulation scheme changes for a short period at night to allow a chance for older equipment to sync up. I don't know that for sure.

But I do have several automatically syncing clocks in the house and have noticed that he syncing isn't as robust and dependable as it was some years ago. For example, switching from standard to daylight savings time and back takes some of them a few days to accomplish, with some of them switching back and forth from day to day before finally getting it right. Don't think that signal strength is the problem. As someone else noted, it sure would be good to know which manufacturers use the new standard! 73 Craig AC0DS From k5rhd at arrl.net Fri Nov 28 20:16:27 2014 From: k5rhd at arrl.net (Randy Diddel) Date: Fri, 28 Nov 2014 18:16:27 -0700 Subject: [Elecraft] VOX SET Command? Message-ID: Good evening, night, day, etc. I have been working hard on getting my KX3 programmed to switch between voice and digital modes using a string of commands assigned to PF1 and PF2. I have them working perfectly except for setting VOX to ON for data modes. In the programmer's manual from Elecraft, it states that "A SET version of the command is planned." Has this been implemented? Does anyone know the syntax? For those interested here are the two strings: For Data: MD6;PA0;MG005;AG001;DT0;BW0400;PC12;PC015;ML000; For Voice: MD2;MG005;BW0240;SWH34;PA1;ML000;AG040;PC110;PA0; These really help out as I can be working JT65 and see a new one on the clusters, switch over, and jump in the side band pile up. VOX works best with WSJT-X and my specific configuration-that is why it would be good to have a bit to set it ON in the string listed above and a bit to switch it off when I switch to voice mode. 73 K5RHD /randy From n0nb at n0nb.us Fri Nov 28 20:19:31 2014 From: n0nb at n0nb.us (Nate Bargmann) Date: Fri, 28 Nov 2014 19:19:31 -0600 Subject: [Elecraft] OT: Changes at WWV, WWVB In-Reply-To: References: Message-ID: <20141129011931.GA23242@n0nb.us> * On 2014 28 Nov 17:41 -0600, Hisashi T Fujinaka wrote: > I heard from my time-nerd friends that the modulation scheme changes for > a short period at night to allow a chance for older equipment to sync > up. I don't know that for sure. I have an older LaCrosse LCD clock that is my shack unit and started to not keep good time around 18 months ago that I noticed at my former QTH. Two years ago I added an amp and I presumed that I zapped something in its receiver as when reset it will keep sync for a time and then lose it. Right now it is 27 seconds fast and was last set at the beginning of April. At work we have a newer LaCrosse LCD clock on the wall and here in the kitchen I have an analog LaCrosse clock (it was purchased soon after the shack clock) and both stay in sync. > Technology Review said there are millions of pieces of equipment that > use the older scheme. It's possible that the shack clock is a victim of this change but the other two were purchased around the same time. One difference is that the shack clock is set to GMT and the others are set to local time. As I recall the clocks sync around midnight so the shack clock could be trying to sync five to six hours before the other two. If WWVB is set to account for this and runs the old protocol at midnight EST (10 PM MST) through midnight PST (1 AM MST), then that would make sense to me. I can try setting the shack clock to CST and see if it stays in sync, I suppose. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

Put KAT500 into tune, HOLD Tune on the K3, and let it tune at your tune power [>20W]. Then put KAT500 into MAN mode and see what happens.

[snip] A number of years ago my late wife and I were touring the western states and went to Ft. Collins. I've looked at several big antenna sites during my travels (NAA, KVLY, VLA, Owens Valley, Guaymas Apollo Station, etc) and thought I'd try to see the WWV complex. So I called them up on the telephone and asked the guy who answered whether I could get a tour of the facility. He was somewhat incredulous and told me in no uncertain terms that they didn't give tours. I said, "What a pity, I've visited other fun sites and gotten tours, I'm an engineer in the defense biz, a ham, yada yada." He said, "Sorry". Then after an, "Ah shucks" from me, he said, "Well, I'll tell you what, there's a contractor doing some work here and the gate is unlocked. Drive in and take a look around, but stay in your car please."

If I set Tune power to 30w and then press Tune, then with the KAT500 in manual it will tune down to 1.2:1. HOWEVER, if I leave it there with the tune power on,the KAT 500 starts showing 1.2, three seconds later, an bunch of relays click, the power SWR scale lights up, the fault line comes on. Then all of a sudden, it is steady again. Shows 1.2:1.. Three seconds later it all repeats. Now if I do it with CW, same thing is happening although it's more difficult to see what's going on due to the intermittent signal.. So it's something with the KAT500 and the antenna.

I don't know this for a fact, but I would assume that they all run at UTC and then run a correction, based on your timezone setting, that shifts it the proper amount for the timezone you set. Ken - Thanks for that info. It helps me understand why my shack clock quit working a long time ago. I moved it all over the place, including in place of another one in another part of the house that worked right, and it would never correct. It was minutes off when I finally tossed it and bought a couple of new ones. They all work fine now. Because of this, I really doubt that they switch back once a day to bring the old equipment up to speed and then switch back. It never corrected itself in over a year.

Somehow the failure of frequency comparators and/or frequency standards that were based on doing a PLL with the CARRIER of the WWVB signal is being extrapolated to the failure of all Radio Controlled Clocks which do not track the carrier but instead read the time code that is imposed on that carrier. This is completely wrong. The new Phase Modulation signal is imposed on top of the legacy PWM signal that has been broadcast pretty much since the beginning. Radio Controlled Clocks that just read the PWM encoding should not be affected by the phase changes of the PM signal, and will still work as before. The reason that some clocks may only get a lock at night is purely an issue of propagation, and will almost certainly be true for clocks located in the eastern part of the US. In fact, that is the primary reason for adding the PM signal, since it can be decoded at lower signal strengths than the PWM signal can be decoded. However, devices like the HP-117 and Spectracom 8170 performed a PLL on the carrier of the signal, since the carrier frequency itself is very accurate. These are broken by the addition of the PM signal, since it is flipping the phase of the signal by 180 degrees periodically. None of the cheap consumer "Atomic Clocks" do this (phase lock the carrier). People have developed external circuits that "reclock" the WWVB signal and allow these type of devices to continue to work. Also, WWVB did shut off the PM part of the signal for a few hours every night during a transition period that ended in May 2013. That is no longer happening, but again this only affects phase locking receivers. Specifically LaCrosse states clearly on their website that their clocks are not affected by the addition of the PM signal. Finally, I don't think there any commercially available clocks, at least at the consumer level, that support the new PM signal at this time. The decoder is patented, and I believe chips that support it are either still in development or only recently released. I'll try to do some more research regarding this.

The following which give the details from the horse's mouth http://www.nist.gov/pml/div688/wwvb-030513.cfm http://www.nist.gov/pml/div688/grp40/wwvb.cfm Consumer clocks and watches that sync to WWVB old and new generally are not affected by the changes to the modulation scheme. The changes do affect frequency standard products that phase locked to the carrier, and some specific clocks that used synchronous AM detection, not your Radio Shack atomic desk clock. The reason WWVB clocks check around midnight is because the reception is generally much better at night and with fewer interference sources switched on there is a better signal to noise available at the receiver. I would venture to say that most clocks that have stopped working as well as they did in the past would be because of an increase in interference levels due to our modern digital lifestyles and poor enforcement of EMC standards, not the change of the WWVB modulation to add PSK which is backwards compatible to the old scheme. 73 David Anderson GM4JJJ > On 29 Nov 2014, at 02:16, david Moes wrote: > > I recieved a new la Crosse clock about two months ago In the instructions it stated that it would only sync a a specific time at night.

Use the stage-by-stage points shown in the manual Appendix A page 14 starting at the middle of the left column. BUT you will have to deviate from the instruction to set the K2 on the 40 meter band - use a failing band instead. If the measured RF voltage is greater than the expected value, that is OK. What you are looking for is the 1st stage in the sequence where the RF voltage is significantly *less* than the expected value. That is the output of the failing stage. 73, Don W3FPR On 11/28/2014 10:50 PM, EMD wrote: > Hello Don, > > Thanks for your reply.

If there is a corroded connection that is heating up and failing, then cooling and reconnecting, it could be happening with CW and not SSB. Try reducing the output of the KPA500 to 100 watts on CW and see if the trouble goes away. We one time had a failure something like this at NY4A. The trouble was traced to a male/female UHF elbow coax adapter, one of the cheeep, cheeep kind that makes the center connection around the bend in the elbow with a spring in the center. This is easier to manufacture than the good kind, which is why they are cheeep. Over time these springs heat up, lose their tension, corrode at the connection points, and display weird symptoms like you describe. Worth checking out. The only reliably non-spring elbows are Amphenol's, where the male center pin screws into the conductor from the female side. Once you know what to look for, you can tell in an instant. Throw all the spring based elbow coax adapters into the trash. They cannot be rehabilitated. If you get any from a supplier, send them back and demand a refund. I walked around a hamfest and easily found 25 of the Amphenol types to take home. You can also get the same kind of symptoms from a PL259 where the braid was not soldered, or has undergone exceptional amounts of flexing, or has lived for a long time at a current max at a high current place. These issues are exacerbated by cheeep coax with lesser amounts of conductor in the shield. Good luck & 73, Guy K2AV On Fri, Nov 28, 2014 at 10:13 PM, wrote: > > > Ok more detail.

BTW, there's a typo in the manual pages, the troubleshooting ones are linked as "Troubleshooting" while the files are "TroubleShooting". Was there in previous version as well.

You sure have that right re interference due to modern digital lifestyle, David. My always-reliable Casio Pathfinder watch updated great until I added a Time-Warner converter in my bedroom a couple of months ago. It updates fine if the converter is unplugged, not at all if it is plugged in. OTOH -- other electronics nearby, including a Roku and old 9" CRT TV, don't impede the update. So mostly the TW converter is unplugged and I use the Roku for watching TV in bed at night. 73, Phil W7OX From pf at tippete.net Sat Nov 29 11:05:31 2014 From: pf at tippete.net (Pierfrancesco Caci) Date: Sat, 29 Nov 2014 17:05:31 +0100 Subject: [Elecraft] K3 FPF firmware load failed In-Reply-To: <1417275412.16239.8.camel@nostromo.NK7Z> (David Cole's message of "Sat, 29 Nov 2014 07:36:52 -0800") References: <87sih24bpb.fsf@snoopy.tippete.net> <1807212665.1526630.1417273972474.JavaMail.yahoo@jws10097.mail.ne1.yahoo.com> <1417275412.16239.8.camel@nostromo.NK7Z> Message-ID: <87k32e3sc4.fsf@snoopy.tippete.net> >>>>> "David" == David Cole writes: David> Along this same line...

I have 3 of the clocks here. Two are not affected but the other one, after any fairly nearby thunderstorm, requires that I remove the battery, let it completely discharge all energy held within (this takes a few minutes as they are very low power drain and apparently have decent sized caps inside) and restart it. It will then lock up and stay that way until the next thunderstorm rolls through. But once a storm rolls through, it will unlock and refuse to re-lock not matter how many times I press the 'resync' button. Something appears to get hosed up in its OS and it declines every attempt to resync it. I can tell when it has lost sync by checking the little 'sync' icon. And, of course, the time is off . . . 73 de dave ab9ca/4 On 11/29/14 11:30 AM, Joe Subich, W4TV wrote: > > Unfortunately the consumer clocks seem to attempt to sync between > 0200 and 0400 *local* (display) time regardless of the time zone. > I have a couple that would display UTC but when I set them to do > so they never sync because their "window" does not seem to include > the optimum propagation window. > > 73, > > ...

The ATU is rated to match antennas with 10:1 SWR at 600 watts, 3:1 SWR at 1000 watts. If the unmatched SWR exceeds 10:1, the ATU might disconnect the amp at a lower power to protect itself from destructive current through its inductors.

Antenna on my end was a Ringo Ranger (vertically polarized) only 12 feet off the ground and the antenna on his end was also a Ringo Ranger but his was on a real short (6 foot) ground mounted mast. There is quite a bit of hilly terrain between us and signals were only 539 both ways but with the low noise on the band copy was real easy. We tried SSB but I don't have the latest Field Test firmware in my KX3 and the transverter is putting out maybe a watt on SSB. It does the full 3.0 watts on CW. Also as previously reported, CW using the internal keyer is kind of messed up. It misses character elements and gets choppy at times. I didn't have time to try external keying with my bug but that will come in another test tomorrow.

I now use CWSkimmer. It appears to be heads and shoulder above what Elecraft coded. Some my buddies use CWget. They seem to really like that program. However, there is technique that needs to be learned. As I stated, I use Skimmer. I set it up for the proper offset and CW tone I use, the same as that for my KX3. At this point the trick is to "zero beat" the station you want to work using the spot button on the KX3. This should align the other guy for proper decoding. You won't do runs this way, but you will work a lot of stations. It worked amazingly well this weekend on 40 where the QRM level was unreal. I use search and pounce for contesting and do pretty well. Try it, and good luck. 73, Barry K3NDM ----- Original Message ----- From: "Tom Blahovici" To: "lmarion" Cc: "elecraft" Sent: Sunday, November 30, 2014 8:13:19 PM Subject: Re: [Elecraft] K3 CW decoder and CQ CW contest That sounds interesting.

Many will tell you you need to start with a straight key, and only when you're competent can you actually try out a paddle. You will find they are universally old, as am I, but get a paddle, plug it in and send! I use the Bencher HexKey from Elecraft at home, my field radio uses a little paddle from American Morse Equipment ... other than the checks I've written, I have no financial interest, etc, etc. I have a couple of standard Benchers too, one I use left handed on the Winkey. I've used several of the "high end" paddles [not mine] and they are very smooth and easy. That's probably not your goal right now, give it time and practice and maybe it will be.

Message-ID: Blond, brunett, redhead....... Chevy, Ford, Plymouth ....... It's mostly a matter of personal preference, but until you "know" CW, you're not likely to be qualified to know what you like. If you want a paddle, the Benchers are very good. There isn't as wide a choice in straight keys. If you have ample funds Google N3ZN Keys. I have one of Tony's straight keys and one of his paddles. They're both wonderful. Many are fond of the Begali line of keys. 73 Ken - K0PP On Nov 30, 2014 8:27 PM, "Tom Blahovici" wrote: > Ok > So I'm sure this is going to get a lot of opinions...

For paddles, the Brass Racer paddle (also Vibroplex, both current production). If you get the Bug bug, buy an older Vibroplex bug with the "I" style damper, and a Vari-Eze (bar style) to slow it down. You can send perfect code from 11wpm up. The Champion and Lightning models had the old"I" damper. You can then extend the Vari-eze straight out the rear of the bug. You can't do that with newer-style dampers. The Viz Vertical is also a great bug that can be slowed down--just ask Tom to make you a double-length weight, and extend it up beyond the damper peg. Some will tell you to buy these brass weights sold for another use, or just use solder. These have never worked for me. If you add too much weight, it screws up your timing--you need the longer arm. Just please do not become one of the many lids who send at 13wpm with their bugs making 30wpm dits. Ewww! And keep your contacts clean to avoid that awful scratchy sound I'm happy to work a QRS sked on the air with you on CW anytime. 73 Eric WD6DBM Tom Blahovici wrote: >Ok >So I'm sure this is going to get a lot of opinions...

There isn't as wide a choice in straight keys. My opinions. :) In today's world, only a purist needs or wants a straight key. I agree the Bencher paddles are very good, and they're a bargain compared to the others mentioned. The least expensive way to buy one is used as part of a MFJ keyer that has one built it. That's because of MFJ's reputation for quality. :) I have 3 or 4 Benchers, all bought used. Paddles don't wear out. Several years ago, I fell for a Begali, and I have a hard time sending with it. One of my friends has an N3ZN that he brings to Field Day and CQP expeditions. It's a nice looking paddle, but I haven't used it. So my advice is to buy a used Bencher, and spend on something else only after you're a seasoned CW op. Most rigs have decent keyers, so you only need an outboard keyer for use with a contesting program to overcome issues with how they work with Windoze to send CW. The Winkey, an inexpensive kit, has become an accepted standard. 73, Jim K9YC From nq5t at tx.rr.com Sun Nov 30 23:11:26 2014 From: nq5t at tx.rr.com (GRANT YOUNGMAN) Date: Sun, 30 Nov 2014 22:11:26 -0600 Subject: [Elecraft] K3 CW decoder and CQ CW contest In-Reply-To: <547BE5DF.6040601@subich.com> References: <0NFV00LZBW9H0I30@VL-VM-MR004.ip.videotron.ca> <547BE5DF.6040601@subich.com> Message-ID: <084CB873-166B-4CB0-A122-1A736A18B354@tx.rr.com> > > A straight key ... any quality straight key.

I can't use a straight key any more for more than 20 minutes without a lot of pain. Have fun! Oh, one more thing--there are fewer lids, asholes, and many more superb ops and just plain interesting people on CW :-) 73 Eric WD6DBM GRANT YOUNGMAN wrote: > >> >> A straight key ... any quality straight key.

It's been nearly 60 years since I went through that. Paddles and keyers did not exist -- we had "bugs," but did start on straight keys. But bugs are inherently different from the paddle/keyer combo. Perhaps one of the CWOps guys who are working with CW Academy can offer an opinion. Mine is that sending good CW is mostly a matter of training our brain and fingers to mimic the good CW that we hear. Unless you're a real straight key "pro," they're far too slow for most on air CW, so if you're going to learn what you're going to use, I don't see the value in going through an intermediate step. BTW -- if you want to get a great start on CW (or build your skills), by all means take advantage of CW Academy. This is the brainchild of K6RB and a few other CWOps members, and it's been quite successful. http://www.cwops.org/ I'm a proud member of CWOps, but not very active. It's a great group. Membership is by invitation. You don't need to be a member to be in CW Academy or the many on-the-air events.

Professional telegraphers got an early version of RSI called ?glass arm?. It appears that you can avoid that with excellent technique, the same way you avoid RSI on a computer. But I have not heard of RSI injuries with paddles. wunder K6WRU CM87wj http://observer.wunderwood.org/ On Nov 30, 2014, at 8:42 PM, Jim Brown wrote: > On Sun,11/30/2014 8:25 PM, Leroy Marion wrote: >> Does not a paddle and keyer give you perfect timing? > > It's been nearly 60 years since I went through that.
