RE: [Elecraft] K2 and data modes
This works but it is very soundcard dependent. If your soundcard has limited input gain or is particularly noisy the direct connection is marginal. The smart solution is a combination of J5 and a 20 dB buffer like the W3FPR/N0SS board. More recent interfaces - microHAM DigiKeyer and microKEYER II - include low noise preamplifiers to work with fixed level audio sources as low as 50 to 100 mV (e.g., J5 in the K3 and the fixed level outputs in many YaeComWood radios). 73, ...

Re: [Elecraft] K2 K3 (ssb)
Hi Trevor, thanks for that. This is an interesting programme, particularly for those without on-board processing, but I was hoping there was a way of evaluating a processed speech pattern without having to listen to it, ie completely objectively. Let's say I have a defect in my hearing (who doesn't have something lacking at our age?) how do I know that I have optimised my own transmitter for my own voice? Listening to my own voice is fraught with variabilities, I might just have a head cold that day or wax in my ears and apply too much boost to the hf end, for instance. The Vshaper is good for showing the spectrum, but speech intelligibility is not discernable from that spectrum. If you have the ARRL Handbook for 1988, the first page of Chapter 7 gives clues but not enough to go on for me. 73 David G3UNA David said: I just imagine that there is somewhere a reference that will help identify those bits of the display which contribute most to clarity and make it easy and more Is this of any use as an analytical tool http://www.dxatlas.com/VShaper/ Trevor G0KTN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 K3 (ssb)
The technique I used to set the SSB settings on my K2 was like this. 1. Transmit into a dummy load. 2. Receive on a known good receiver (Drake 2B in my case). 3. Record the receiver output in a high fidelity recorder (Cakewalk). 4. Listen to the recording on studio headphones. This allowed me to hear how my voice my mic sound through my rig. I was able to vary the TX level in the recording to simulate S-9+ signals or S-5 signals so I could see how things shifted as the signal went down.

During the time that Don was selling this device, he went from suggesting that it be installed on the left side panel of the K2 (see bottom image on the link above), to installing it between the FP and CTRL PC boards. See: http://w3fpr.qrpradio.com/download_files/FP-CB%20mounting%20photos.pdf Moving from the original installation point to the second site requires that all components be laid down flat against the PC board (e.g. low-profile), which the original PC board design did NOT accommodate terribly well. As I type this reply, I am _IN_ the process of redesigning the PC board layout to more readily accommodate standard components laid flat against the board. I have not yet decided whether to actually offer this PC board for sale 'in quantity' or to just make a few (in the kitchen) and then offer them on a per order basis. If demand was higher (I think Don pretty much answered most of the screaming demand for this device), I'd have a 'batch' run off at FAR Circuits, but this may not be the case. Regardless, it appears that new boards will be available very soon... probably within a week or two. If you'd like to obtain a board, please contact me.

Re: [Elecraft] K3 if isolation of softrock lite used as panadapter
I assume a simple MMIC amp plus a simple resistive attenuator circuit will provide enough isolation and also provide for matching levels up/down as may be necessary. At least, that will be my first cut at the problem unless somebody else comes up with a better plan before my K3 arrives. At down east microwave ( http://www.downeastmicrowave.com/cat-frame.htm ), see the http://literature.agilent.com/litweb/pdf/5967-6159E.pdfINA10386 (DC-2GHz, 24dBG, 3.5dB NF +14dbm 1dB Gain compression ) for only $5. Very easy to use something like this, I think. Depending on the signal level of the K3 IF output, we might get enough isolation from a resistive attenuator alone and still have a usable signal level on the softrock panadaptor. I would much prefer a plug and play manufactured solution if it takes more than an attenuator, but not an expensive one.

[Elecraft] K3 #338 - Alive and well
Hi all, Just a couple of notes on my build of K3 #338. Here are some pics and notes on my web site: http://w8fgu.home.comcast.net/~w8fgu/k3build.html It arrived here on 2/6 and was built in about 9 hours on 2/8. I did a thorough inventory and was only a couple of 1/4 black pan head screws short. I substituted a couple of 3/16 screws until replacements arrive (they were on one of the panels). The packaging of this thing was amazing and very well organized IMHO. The documentation (Ron) was outstanding - anytime I wasn't clear on what I read, there was always a good picture or illustration to light the way. Like others have said, if you follow the instructions to a tee, you cannot go wrong. It really went together quickly and was a pleasure to assemble. I found it interesting that all of the talk around this radio has been mostly performance spec related (as well it should be), but I found the mechanical engineering equally as impressive. There are some really tight tolerances on this radio and when it is assembled, it really shows through. I did have some difficulty with placing the front panel PCB on the front panel itself. The two small led's over the power control were slightly bent to the left. I carefully moved them back in place and all mounted well. I only had a couple of problems - and both were my fault. I torque'd down one of the jack screws for the RS232 connector snapping it off. I was able to remove the KIO3 board and remove the rest of the screw. Fortunately, I had another one lying around to replace it. The second was a little stranger. All calibration went as expected, but I noticed when playing around with the radio that when I adjusted the power level from 12 to 13 watts (when the relay to engage the KPA3 would kick in), I would hear a noticeable drop in signal level and see a 4 - S-unit drop on the meter. I pulled the KPA3 module and began to inspect it when I noticed that I had crushed Q9 near the plug in connectors while placing it on the KPA3IO board. What was worse is that just days prior, Larry Phipps, N8LP, had just told me to watch out for that very thing in an email. In my case, the leads were all shorted together, but it was still intact. So, I carefully bent it back to a somewhat normal position and it seems to work just fine. I ordered a new one from Elecraft and will replace it when I receive one. Yesterday, after playing around with the receiver for a little while, I wanted to see if I could make a contact. I usually like to hang around the slow cw portions of 40m, but with the WPX contest going, I opted to try it out on 30m. I called cq just a couple of times and worked WB0YRM, John, in Longmont, CO with 50 watts and received a nice signal report. I felt kind of bad, because I was not totally attentive to our QSO, playing around with all of the nice features on the K3. With an unfamiliar radio, it is real easy to make the other ops signal disappear ;-) Just playing around with the DSP noise blanker and noise reduction settings, I'm amazed at what I can get rid of compared to my K2. I've only just begun to scratch the surface of what I can do with this thing and I look forward to all of the firmware upgrades. Speaking of firmware upgrades, after downloading the upgrade utility, it downloaded and upgraded my K3 without a hitch. Nice job on that utility. The RX equalizer is a nice touch as well. I thought that my K3, through some computer speakers, sounded a little thin compared to my K2. I adjusted the equalizer while listening to an AM broadcast station and everything else sounds great to me now. Back to playing some more tomorrow. 73, Dave W8FGU K2 #5099 K3 #338 - KAT3, KPA3, KBPF3. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 if isolation of softrock lite used as panadapter
Thanks - the post was actually captioned 2nd Run on Z1 Buffer Amplifier. For the K3, the universal model of the Z1 would be usable and will provide around 70 dB isolation, which, when combined with the isolation in the K3's internal source follower IF buffer pick-off amplifier should be enough to let a Softrock receiver work without interference to the K3. I've delayed receipt of my K3 until the 2nd receiver issues are sorted out, so I can't run tests, but based on the numbers involved (Softrock local oscillator output around -40 dBm if my memory is correct) the Z1 and K3 internal isolation in tandem should be adequate. A related issue is whether it is necessary/desirable to interpose a bandpass filter between the K3's IF output and the Softrock receiver input. There's a lot of stuff that comes out the K3's IF output port, signals from internal oscillators, etc. I don't have an opinion on whether a 300 or 400 KHz wide bandpass filter will be necessary or not. Again, that requires some measurements that I can not perform until my K3 arrives. Since the Softrock works with an antenna connected to it, I suspect that additional filtering won't be required, but it would be nice to verify my suspiscion. I also have a connectorized version of the buffer amplifier, but had not decided whether to make it available or not. I use them around my shop when I need extra amplification for a particular project.

[Elecraft] [K3] 6m power regulation
Ron It's a known issue. Mine is the same. 73 Dave, G4AON K3/100 #80 On all bands (except 6m) I can increase the power up to 12.0W in steps of 100mW. With KPA3 on Bypass (probably the same without the PA) that's the top end (firmware controlled as expected). With the KPA3 on Normal the amplifier kicks in just over 12W (relais clicks, RF scale changes) and the display jumps to 13W. Nothing strange so far. On 6m however the maximum power with KPA3 on Bypass is 8W (probably due to limitations of the LPA). With the KPA3 on Normal the amplifier kicks in just over 8W and the display jumps to 13W. No possible setting between 8W and 13W. This is the strange bit. SNIP PE8E, Ron. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] [K3] 6m power regulation
When playing around with the K3 (or should I say: during operational education) I noticed something that haven't read or seen mentioned anywhere. On all bands (except 6m) I can increase the power up to 12.0W in steps of 100mW. With KPA3 on Bypass (probably the same without the PA) that's the top end (firmware controlled as expected). With the KPA3 on Normal the amplifier kicks in just over 12W (relais clicks, RF scale changes) and the display jumps to 13W. Nothing strange so far. On 6m however the maximum power with KPA3 on Bypass is 8W (probably due to limitations of the LPA). With the KPA3 on Normal the amplifier kicks in just over 8W and the display jumps to 13W. No possible setting between 8W and 13W. This is the strange bit. At the moment I do not have a accurate powermeter on hand, so I didn't measure the output, just looked at the display. Not a priority issue, maybe a documented fact that I overlooked, but it would be nice to know if this behaviour is present on all K3's (possible technical limitation of LPA and/or firmware issue) or just on mine (possible hardware error or calibration issue)? Maybe this is also one of to be changed items on the famous firmware-list? PE8E, Ron. K3 #00201 (incl.

[Elecraft] 2nd Run on Z10000 Buffer Amplifiers?
I'm contemplating a second kit run on the Z1 IF sample buffer amplifier, and I'm interested in whether there is any interest in a second run. For the unfamiliar, the Z1 kit is a small PCB that pulls an isolated sample of the K2's IF signal out and makes it available on an SMA connector installed on the K2's rear panel. There's a great deal more information on it that can be obtained by reading the manual at http://www.cliftonlaboratories.com/Documents/Z1%20Buffer%20Amplifier%20Assembly%20%20Operation.pdf. Also, http://www.cliftonlaboratories.com/k2_interface.htm provides more details. My thought is that with the increasing interest in using a Softrock receiver as a K2 panadapter, there needs to be a way to extract the IF signal and to prevent the Softrock's nasty local oscillator signal (around -40 dBm or stronger) from getting back into the K2. That's exactly the purpose for which the Z1 was built. The original Z1 price was subsidized by the associated Z90 panadapter, which will not be the case on a second run. Hence, there will be a price increase to $34.95. If I go ahead with the second run, this price will include the PCB, all parts, a cable with the miniature coaxial cable and SMA connector installed and a printed copy of the assembly and operation manual, and postage within the US. If sufficient interest is found, I would make the second run available beginning in mid-to-late April. The kit can be built either in the K2 version (which includes bandpass shaped response) or the broadband version, suitable for receivers with a different IF. Price is the same, but the universal and K2-specific kits will be different products. Please respond privately to me.

[Elecraft] K3: Interim Build Report
Dave, Your statement: 'Several reports are surfacing here and elsewhere from very reputable sources about the current lack of SSB bandwidth'. Could you give more information on your statement above. I have not heard of any SSB bandwidth problem and would like to here the details. Thanks and 73, Joe N9VX K3 S/N waiting -- Dave wrote: Hi Everyone, As I posted here at mid week, K3 #371 arrived from Aptos in fine shape. I have begun the build and thought I would share some comments both positive and negative with all. You opinions of course will most likely be different but here are mine so far: Positive: The kit was packaged magnificently. The care in packaging is first rate. The manual is by far one of the most comprehensive I have seen in building many kits over the years. Clear, concise and detailed but very logical and easy to follow. Build quality of the boards is indeed elegant. Fit and finish is simply excellent. Tolerances are amazing. It is a work of engineering art. Congrats to Eric and Wayne of all of this. They should be proud of their baby. Negative: Yup I have a negative. Of all of the kits I have built over the years, many of them fairly complex, from Heath, LDG, W9GR and many others, this is the first to arrive short parts/hardware. And while the shortage is minor, it is specialized and significant enough to stop me cold in the build process and add yet another week to the final K3 experience. Simply put, it has been deflating. Yet more delay. While Elecraft was attentive to this matter over the phone and in a response from K3Support, I am still not sure if the parts are headed this way as no confirmation has been positively received. This will be my last kit experience. I should have bought it factory assembled as I planned originally. But I bought into the kit mystique. Never again. Concerns: I am both a CW and SSB operator as non-contesting DX'er. SSB TX issues are important to me. Several reports are surfacing here and elsewhere from very reputable sources about the current lack of SSB bandwidth and the lack of more powerful modulation. I urge Elecraft to address these issues ASAP (now perhaps with more priority than the second receiver.) This will be a deal breaker for me if not rectified. IMO it should have been correct out of the box. This K3 will be evaluated against my highly modified Ten Tec Omni V.9 which has for my operating requirements beat out every transceiver on both CW and SSB since its arrival here at this QTH, bar none, including my Pro III which for all its true Rx warts is a pretty darn good value for the $$. I paid my $$ and took my chances and hope that this will all get rectified in the end. And for those of you who may think that I should not air complaints in public, I ask, did yours arrive complete?

The stand-by current of the K3 varies considerably depending on how long the power has been disconnected before the measurement is made. I measured the current of my K3 after the power had been disconnected for about six hours and the current was 15mA as measured on a good quality moving-coil (d'Arsonval) type of meter. Having used my K3 and then switched off, the current was 65mA and then reduced slowly. I can only assume that the variation is due to internal circuits (capacitors, etc) being recharged after the POWER button switches the K3 off. 73 -- David G4DMP/G3KEP Leeds, UK -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 and data modes
Nick: Wiring up my K2 for data modes - recall seeing a post from someone who had done an easy mod to get audio out (i.e. line out) which is not affected by the AF gain control. Have looked through the archives in vain - can anyone help please? 73 Nick G3RWF That was Don Wilhelm, W3FPR. Don WAS selling a fixed-output audio device which he'd designed and for which I'd laid out the PCB design. See: http://w3fpr.qrpradio.com/K2_Fixed_Audio_Output.htm Just got a note from Don yesterday that he's sold the LAST(!) of his PC boards and is NOT planning on ordering more for resale. During the time that Don was selling this device, he went from suggesting that it be installed on the left side panel of the K2 (see bottom image on the link above), to installing it between the FP and CTRL PC boards. See: http://w3fpr.qrpradio.com/download_files/FP-CB%20mounting%20photos.pdf Moving from the original installation point to the second site requires that all components be laid down flat against the PC board (e.g. low-profile), which the original PC board design did NOT accommodate terribly well. As I type this reply, I am _IN_ the process of redesigning the PC board layout to more readily accommodate standard components laid flat against the board. I have not yet decided whether to actually offer this PC board for sale 'in quantity' or to just make a few (in the kitchen) and then offer them on a per order basis. If demand was higher (I think Don pretty much answered most of the screaming demand for this device), I'd have a 'batch' run off at FAR Circuits, but this may not be the case. Regardless, it appears that new boards will be available very soon... probably within a week or two. If you'd like to obtain a board, please contact me. I will be happy to send you a PDF of the new board layout if you are interested. First, visit Don't links (above) to see what is required for the installation.

[Elecraft] K2 on order
Hello, This morning, I ordered a K2. I figured it would take a few days to process the order, pack the box etc. I received an E-Mail a while ago, it has already been shipped. It should be here Wednesday. The UPS delivery date is not yet available, but normally from California to Utah is normally two days. The next week or so, will be fun. I love building stuff!!

RE: [Elecraft] Dayton 2008
I have not seen one either Just ordered one. 72, Bill K9YEQ K2 #35, K2 # 5279, KX1 #35, Mini Modules, etc. -Original Message- will apologize in advance. I was wondering if Elecraft is planning to be at Dayton Hamvention. I have not been to Dayton this century and was looking for excuses to go. After all, I think that I am the only Elecrafter left that has not seen a K3 in person.

[Elecraft] K3: KBPF3 and KFL3A-6K
Roger, I have been lobbying from the sidelines that when the (not yet available) FM filter is ready that it should be usable for AM and FM reception both, because 5 khz is not enough IMO. SSB reception through this filter also makes sense to me. At present, if you don't have the AM 5khz filter, the 2.7 khz filter is used on receive and there is no AM transmit. The FM filter is supposed to be ready by the end of this week, don't know if it will be or if the firmware is ready for FM, my cat control program cannot set the FM mode yet. All of these are fine tuning details, the radio is absolutely worthy of getting serious about!!! [Elecraft] K3: KBPF3 and KFL3A-6K Roger Marrotte rmarrotte at verizon.net Mon Feb 11 20:38:21 EST 2008 I'm finally getting serious about buying a K3. Up until now I have not paid much attention to all the details, especially those concerning the filters. For now I'll not get the 2nd RX. It's not available yet, so maybe I'll get it later on. I'll get a couple of CW filters for now. I do mostly CW. I'll get a narrow 1.8KHz SSB filter. I do get on SSB sometimes. I sometimes like to listen to AM but will probably never transmit on AM. I've read the archives but I'm still not absolutely clear about the need for the KFL3A-6K filter in addition to the KBPF3 filter for AM listening. I see the need for the KBPF3 for AM listening outside the ham bands. What will the KFL3A-6K filter do for a casual AM listener? Will there be a noticeable narrowing of the AM signal without it? If the AM will sound better and/or be better filtered with it, I might as well get it. I'm cheap but not that cheap.

[Elecraft] Quiescent current drain K3
Have mine on an AC strip - off is OFF.
