[Elecraft] K3 Problems
Jettie, W6RFF Just got my K3 back from the factory, as they did not put a filter in the sub RX. Last night and this afternoon I worked quite a few stations on 20 meters, and everything seemed ok. After dinner I turned the K3 on and it would not operate correctly and HI SIG appeared on the screen. Evidently there is a strong signal blocking the Main RX. The SUB RX seemed to be OK as I could tune in signals on 40 meter CW. Also there seems to be quite a delay after most buttons are pushed, and some do not work. Some one had commented, yesterday about a loud noise in their RX, but it had eventually stopped. Also the K3 will not transmit. I went through all of the configuration, and nothing had changed. (had problems getting into config mode). Any ideas?? Jettie B.

Re: [Elecraft] Latest Sherwood table
I wonder how such a high performance filter would work in the K3? Not that its needed in the K3. However in the interest of science, it might be a worthy pursuit. It also might push the K3 well ahead of the FT5000 in ultimate performance. Not very well since it's at 70 MHz. ;-) The Inrad filters are already better than whatever is in the FT5000 since Sherwood measured ultimate rejection in the K3 at 105 dB vs 90 dB for the 5000. 73, Bill W4ZV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Latest Sherwood table
Is there a non-engineer's guide to the Sherwood table for those of us who are not engineers? In particular, the table is sorted by Narrow Spaced Dynamic Range, and I see that the FT5000 is listed first, but the K3 also gets a 101 in that column, albeit with a pf footnote instead of just an f. I decode these footnotes to be f = Measurement was Phase-Noise Limited And pf = Measurement was Phase-Noise Limited and was with 200 Hz 5-pole filter OK - so why is the FT5000 at the top of the list? Why no indication of what filter was used in the FT5000? What is the second sort column for the table? What puts the FT5000 on top? What does this table really tell us? It seems that both of these receivers are pretty close as many of the numbers are similarly different from those listed below them. When a parameter is higher or lower - which is better? I presume that the higher the narrow-spaced dynamic range, the better, but what about 100kHz blocking (for example). Is higher or lower there better? The K3 is a 140 on that one, and the FT5000 is a lowly 127. The Down-conversion Kenwood 590 gets a 144 in this column - is that better or worse than the K3? But, the 590 only gets an 88 in the narrow-spaced dynamic range, so I guess that means it's much worse?

Re: [Elecraft] K2 output power on 10 meters
Mike, The K2 maximum output power on 10 meters varies due to component tolerances and care taken during construction. Since you have apparently done the normal things to improve it, and the power is still low, it may be time to consider component tolerances - primarily for the Q5 and Q6 stages. One easy way to bring up the 10 meter output power is to change Q6 to a transistor that typically has better high frequency performance. The 2SC2166 that is being shipped with new K2 kits seems to produce better output on 10 meters than some older K2s that I have worked on - I guess this is tolerance drift over time, but that is only a guess. Another way to increase the 10 meter output power is to change Q6 to a 2SC5739 which has better high frequency performance specification than the 2SC2166. If you do make this change, also change the value of R46 from 270 ohms to 330 ohms to keep the Q6 transistor at a cooler temperature. 73, Don W3FPR On 12/30/2010 11:36 PM, Mike and Alicia Fanning wrote: Hi all, I have been tweaking on my K2 for the last several days trying to get the transmit power up to snuff on 10 meters.

Re: [Elecraft] Latest Sherwood table
Bob, I can't think of an easy answer - mainly because many or the parameters tested are in the realmm of engineering, and as such use engineering terms to achieve some level of communications clarity. In short, if you do not develop some understanding of the terms, there is no easy way and must involve some study. I would suggest two things - first is to try looking up each of the parameters on Wikipedia, second, do some study of the Receivers section in the ARRL Handbook to provide you with some understanding of how the various parameters work together. If you want to gain a little better understanding, look at the ARRL Testing procedures (for Receivers) - you really don't have to read the entire test procedure, usually the Purpose of each test will provide some insight. You can find the ARRL Test procedures at http://www.arrl.org/files/file/Technology/tis/info/pdf/Procedure%20Manual%202010%20with%20page%20breaks.pdf Lastly, some parameters will be more important to one type of operation than others. Exactly which ones relate to your operating tastes and style will vary. A contester or avid DXer will want good performance in the narrow spaced dynamic range because he must work in a section of the band crowded with signals and does not want the stronger ones to overload the receiver. If your operating style is more of the ragchew variety, that same parameter may not be important to you since you will likely QSY if QRM is nearby rather than trying to stick it out and work within the QRM area of the band. 73, Don W3FPR On 12/31/2010 7:42 AM, Bob Naumann wrote: Is there a non-engineer's guide to the Sherwood table for those of us who are not engineers?

IMO, while Bob's efforts have long been to document very close dynamic range, it seems that this one singular focus tends to skew the table somewhat (I'm not just saying that because the K3 is now presumed second rate by those who don't understand all of the parameters fully). I say it because I think one must take all parameters into account as I think they show that focusing strictly on one area leads to deficiencies in other areas. If, for instance, the Yaesu engineers consciously set out to acheive the top spot based soley on 2 kHz BDR, they won that battle but lost the war as other numbers indicate poorer performance for the FT-5000. IMO, the K3 should rank higher as the overall numbers are better and more consistent than the FT-5000. But, it's Bob's data and website and he has decided how to rank the various transceivers.

Re: [Elecraft] Latest Sherwood table
Thank you, Don. To make what I'm saying clear, I do understand that this is all very complex and decoding it all takes a deep level of understanding, which I suppose comes naturally to engineers and people who enjoy that sort of thing. I'm no longer one of those people. Even though I have been involved in electronics for decades and was an Electronic Engineering Technician for many years until I went to the dark side of management back in the 80's. So, I can/could understand what each of the terms means - but I don't see from the table how they were used to reach a conclusion of which radio is ranked #1. I guess that what I'm looking for is an Executive Summary with some answers to my specific questions: 1) Why is the FT5000 at the top of the list? (And not the K3 when they both get a 101 in the column the table is sorted on?) Is it because the FT5000 is newer so it goes at the top? 2) Why no indication of what filter was used in the FT5000? (Is that significant or not?) 3) What is the second sort column for the table? (which I presume puts the FT5000 on top since they seem equivalent in the Narrow Dynamic Range column with 101 for both). I think that even if I were to gain enough knowledge to fully explain each parameter in engineering terms, I would still be guessing at what criteria Rob used to rank these radios. A simple explanation like: Even though the FT-5000 and the K3 have the same Narrow Dynamic Range measurement, the ___ of the FT5000 puts it ahead of the K3 in the table.

Re: [Elecraft] Latest Sherwood table
The Yaesu car may be on top because of slightly higher acceleration, but I'm watching what people are driving around the race track, ya know those guys who have to add *everything* up to finish the race in front. The Yakencom boys keep throwing something or the other overboard to try and match the K3. And I would have thought that the Kenwood 590 would have finished in better shape (that's what's new on the list BTW). If you bought your K3 in a fit of p***s envy, you're sure to get knocked down on some list sooner or later. But if you bought it for all those high numbers AND reasonable cost AND two equally excellent receivers AND true diversity AND customer support AND constantly evolving firmware AND configurability AND an owner who's always listening to the troops AND ... , then the other guys on the list don't really compare. I note that the one other REALLY sharp RX on the list (Perseus) does not have a transmitter inside it's case. PS, after listening to a friend for a while last night, I recommended a 590 to him. Whatever else, the K3 has had an enormous effect on the state of the art. 73, Guy.

Re: [Elecraft] Latest Sherwood table
The numbers are there and pretty straight forward. What they really are saying is that unless you are operating under very stressful conditions, you can pony up your money and take your choice. I have 2K3s, 1 Eagle, 1 TS590, 1 ORION ll, and 1 FT5K. And I have many other radios. At this level the performance is a given.

Re: [Elecraft] Latest Sherwood table
Guy: - The Yakencom boys keep throwing something or the other overboard to try and match the K3. And I would have thought that the Kenwood 590 would have finished in better shape (that's what's new on the list BTW). If you bought your K3 in a fit of p***s envy, you're sure to get knocked down on some list sooner or later. But if you bought it for all those high numbers AND reasonable cost AND two equally excellent receivers AND true diversity AND customer support AND constantly evolving firmware AND configurability AND an owner who's always listening to the troops AND ... , then the other guys on the list don't really compare. -- Completely agree... And dont forget the weight factor... Its much harder to cart a pair of 7800'ds a kilometer across the soggy Russian Tundra than to carry a pair of K3 in each hand...

Re: [Elecraft] K2: Change filter BW without realigning filters?
Andrew, The easy answer is YES. The Lower sideband setting will not change much, but the upper sideband BFO will change a lot. Do you have the KSB2 fitted to your K2? If so, I recommend you use it for a wide CW filter rather than using the variable filter at such a wide width - at wide widths (over 1.5 kHz) the filter passband becomes quite ragged within the passband, and would be quite noticeable with CW although it will provide intelligible SSB copy. If you choose the OP1 filter for a wide CW filter, just set the BFOs to the same frequency (or DAC value) as you have for a properly aligned SSB filter. In other words, 1.50 kHz was chosen as the wide CW default because that is about the widest that the variable filter can be set and expect a relatively flat passband. Use Spectrogram and a wideband noise generator for best results when setting the filter BFOs. If you are not familiar with the process, take a look at part 3 of the K2 Dial Calibration article on my website www.w3fpr.com 73, Don W3FPR On 12/31/2010 11:24 AM, Andrew Moore wrote: For best performance do I need to realign BFO settings (Spectrogram etc.) if I change the filter bandwidth setting on the K2? ex: FIL1 from the usual 1.50 to 2.49 etc... --Andrew, NV1B __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Running DM780 with the K3
Mark, Please explain what you mean by waterfall display is super messed up - the K3 defaults to a 400 Hz width for DATA A and that would show a narrow band on the waterfall until you increase the width. BTW, DATA A is the only one you should use, the other data modes are for RTTY or PSK generated by the CW paddles (and may generate very strange waterfall displays). Note also, that if you select the operating band/frequency and mode by clicking in DM780/HRD, you may end up in USB mode instead of DATA mode - I use the K3 tuning for that reason. Maybe Simon will fix that someday. For transmit, make certain you have set the Line-in level so that you obtain 4 bars on the ALC display with the 5th bar flickering, then set the power with the K3 power control, ignoring the advice in many interface boxes to set the power level by controlling the audio level - that will not work right with the K3 (nor with the K2). I believe it is Signalink that normally provides microphone level audio to the transceiver, but there is a jumper inside to increase it to line level. To drive the K3 Line-in, you must change the jumper in the Signalink. 73, Don W3FPR On 12/31/2010 2:23 PM, pastor...@verizon.net wrote: I am currently using a signalink USB with HRD and DM780.

It already has dedicated direct FSK and PSK with your CW paddles. But there is also an option to use Data-A mode to operate PSK or any other audio based digital mode in conjunction with soundcard-based digital mode software. It is usually best to use a second soundcard for your audio-base digital modes. This way you will not be plagued with Windows sound effects in your waterfall or in your transmitted signal. If you do not have that option, you can always go into your Windows control panel and open “Sounds and Audio Devices.” Select the Sounds tab and set Sound Scheme to No Sounds. Here are the steps to setup for PSK using Data-A mode: 1. Set your soundcard volume to about 50%. 2. Connect soundcard output to the K3 LINE-IN. 3. Connect the soundcard input to the K3 LINE-OUT. 4. Set Menu item MIC SEL to LINE IN. The K3 will remember this MIC SEL source next time you use digital modes. 5. Set mode to DATA. HOLD DATA MD to choose Data-A using the VFO B knob. 6. Set power to ~20W (just something to start with). 7. Use the MIC control to set the drive level so that your see 4 bars of ALC and output is equal to, or just below what you dialed in (20W in this case). Compression is locked at zero automatically when in Data mode and cannot be adjusted. When setup this way I get excellent PSK31 results with TX IMD at ~ -26 dB to -32 dB - a very clean signal. FOR PTT You can use a separate line for PTT from a computer COM port to the ACCY connector or the RCA PTT connection on the back of the K3. This requires a simple circuit using a transistor and resistor between the COM port and the K3. You can find this circuit on many ham radio websites, including the AA5AU RTTY website. You can also use the RS-232 serial connection if your software allows you to set it up that way. Not all software allows you to do this. Some programs will also allow PTT via CAT command. In the K3 CONFIG menu, set PTT-Key to either RTS - OFF or DTR - OFF. Then in your software set PTT to either DTR or RTS as appropriate to the same COM port the radio is connected to. hope there may be something in there that will help. if not feel free to use exercise your delete key! -- GB 73 K5OAI Sam Morgan On 12/31/2010 2:36 PM, Don Wilhelm wrote: Mark, Please explain what you mean by waterfall display is super messed up - the K3 defaults to a 400 Hz width for DATA A and that would show a narrow band on the waterfall until you increase the width.

Note also, that if you select the operating band/frequency and mode by clicking in DM780/HRD, you may end up in USB mode instead of DATA mode - I use the K3 tuning for that reason. Maybe Simon will fix that someday. For transmit, make certain you have set the Line-in level so that you obtain 4 bars on the ALC display with the 5th bar flickering, then set the power with the K3 power control, ignoring the advice in many interface boxes to set the power level by controlling the audio level - that will not work right with the K3 (nor with the K2).

Re: [Elecraft] Latest Sherwood table
Hi Bill I understand the differences in IF frequencies. The question still remains, how much extra IMD dynamic could be squeezed from the K3 if high performance 8mhz roofing filters were used. We have seen no data on the K3 filters that quantified their impact on IMD dynamic range. PA3AKE has shown that careful selection of crystals and building a roofing with due care contributes a significant amount to the ultimate IMD dynamic range. http://www.xs4all.nl/~martein/pa3ake/hmode/roofer_intro.html I wonder if a company like Network Sciences did build an improved 8 mhz filter how much performance increase we would see.

[Elecraft] [K3] Question about APF with Diversity Rx enabled
GA: Perhaps someone (Wayne or Lyle or ??) could provide some further explanation about how the APF is implemented when Diversity RX is turned on. As I understand it, (at a high level) with Diversity turned on, both the MainRx and SubRx are turned on, use the same bandwidth roofing filters and the main VFO A provides the same LO signal for both receivers resulting in audio from the MainRx going to the left ear and the SubRx audio going to the right ear. If the APF is now turned on, does the DSP1 for the MainRx and DSP2 for the SubRx now apply that filter functionality to the two separate Main and SubRx audio signals so that turning the shift knob actually tunes the peak in both of the separate audio streams together? I'm just trying to get a better understanding of what's going on in the radio.

First, the K3 must be in the DATA A mode, and you need a cable from the output of the sound card to the line input of the K3, and the playback mixer in your computer must be set to send the .wav generated sound to the computer output. Second, you need to get the K3 to transmit. One VERY easy way to do that is to use VOX. That's what I do for both PSK and RTTY. You can also do it by command from DM780. Don't ask me how -- it's been a couple of years since I've run PSK. Third, you have to place DM780 in transmit mode. Study the doc for DM780 for answers to both questions. Next, you need a serial connection between the computer and the radio. Use a real serial connection if your computer has one, or a USB to serial if you don't. There's a lot of detail about the various connections and how to set levels in http://audiosystemsgroup.com/HamInterfacing.pdf and in http://audiosystemsgroup.com/RFI-Ham.pdf Both are free downloads. It is VERY important to set levels correctly. If you don't, you can create a lot of interference to other PSK users.

Re: [Elecraft] Panadaptor for K2
Rick, A panadapter that will work with the K2 has already been developed. It is the Elecraft P3. Yes, you must provide an IF output from the K2, and that has been accomplished by Clifton Laboratories in the Z1-K2 buffer amplifier. Another solution that involves a computer display is afforded by LP-PAN (or a SoftRock receiver). Check the LP-PAN and/or the Softrock Yahoo Groups forums for more information on those solutions. I believe the present solutions are much easier (and offer better performance) than attempting to convert one of those older Panadapters. 73, Don W3FPR On 12/31/2010 5:02 PM, n...@aol.com wrote: Setting around here wondering what the world has in mind for the k2 I wonder if anyone has ever contemplated the possibilities of modifying a monitor scope, such as the HO-10, SB-610, Ho-13, or ones oscillocope to use as a panadaptor.

Re: [Elecraft] Latest Sherwood table
Both the Inrad and Elecraft filters use crystals that are hand- screened for low IMD. We built several high-performance test fixtures for ourselves and Inrad to make sure this was done consistently.

Re: [Elecraft] K2: Is there an ideal power supply voltage?
Andrew, For K2 receive, as long as the power supply voltage is between 9.5 volts and 15 volts, there will be no change in receiver performance. The receiver circuits all operate on the output of the 8 volt regulator (well, except for the AF Amp) which will supply 8 volts until the voltage drops below the regulator's dropout voltage (it is a low dropout regulator). For the same reason, a voltage change will not change the receiver alignment. The 4 MHz reference is not critical during operation since it is not used dynamically. It is important that it be aligned just before doing a CAL PLL and/or a CAL FIL operation - it is used at that time to store DAC values into EEPROM, and those DAC values do depend on the frequency measured by the internal counter probe - and that frequency is dependent on the 4 MHz reference oscillator frequency at that time. 73, Don W3FPR On 12/31/2010 5:28 PM, Andrew Moore wrote: While the K2 is capable of operating from a range of input voltages, is there an ideal power supply voltage it prefers to see for best receiver performance?

Re: [Elecraft] K3 DM 780
Don, Listen to the output of your soundcard with headphones (or your computer speakers) while sending with PSK31 - if you hear the PSK31 warble, then your soundcard output is normal (you will likely only hear it in the left ear). Please verify this before anything else - if the soundcard does not output the tones on the left channel, things will not work. Use VOX initially just to keep things simplfied - others have suggested VOX settings. For the time being, turn off PTT -- KEY in both the K3 and DM780. Actually, using HRD/DM780, it is best to key the transmitter through the RS-232 port than to use the DTR or RTS signaling (DM780 activates transmit through HRD - but HRD must be configured to activate transmit too). If you use DTR or RTS, those lines will become active for a short period when you power the computer on, and will signal to K3 to go to transmit mode. Put the K3 into TX Test and verify that the ALC meter goes up to 4 bars with flickering of the 5th bar. Adjust the Line-in level or the soundcard output level to produce that amount on the ALC meter. A word about the K3 ALC meter - it does not indicate ALC until the 5th bar - the lower levels are more like a VU meter to allow you to set the audio level below that of the onset of ALC, 73, Don W3FPR On 12/31/2010 4:27 PM, gold...@charter.net wrote: I want to use DM 780 with my K3 to work either CW or one of the data modes.

Re: [Elecraft] Latest Sherwood table
What gets me in a K3 is that there is still some room in there, even after installing the KRX3 to the 100W transceiver, to add something else. So far the possibilities haven't tickled my fancy. But the way it is put together allows some intriguing homegrown devices. We ARE around here designing some quiet 160 RX antennas SPECIFICALLY for diversity, kind of like a 4 square, where one ear listens to the selected direction, and the other ear listens to an equally quiet channel of the two directions adjacent to the selected. No K3 and we wouldn't even be THINKING of such a thing. Now the RX antenna switch box HAS to have a diversity port on it, and sending just ONE direction from the array back to the RX is intolerable. Two runs of flooded RG6. Whoodda thunk it... 73, Guy.

Re: [Elecraft] spectrogram
Tom, There is one benefit for me when using Spectrogram 16 - it has a larger display area, and therefore greater resolution and interpolation is available. BUT, it has more setup parameters and a few more bells and whistles that are of no use to me. Version 5.17 is entirely suitable for aligning the K1/K2 filters and does match your documentation for setup and operation. Other versions have different setup data. So my recommendation -- if you are a newby to using an FFT based audio spectrum analyzer, download version 5.17 from Tom's website and follow his documentation for setting it up. If you are interested in further enhancements after you have become familiar with the operation, then download version 16 (the last freeware version) and do whatever you wish with it - it has a lot of capability. 73, Don w3FPR On 12/29/2010 4:10 PM, Tom Hammond wrote: John: There are several(!) versions of Spectrogram available.

You CAN use newer versions of Spectrogram with my alignment docs, but there's absolutely NO benefit in doing so and newer versions offer features you will not need nor wish to use.

Re: [Elecraft] K2: Is there an ideal power supply voltage?
Since the regulator is a low drop out, the ideal voltage would be about a volt over the minimum input for the regulator. That keeps the dissipation at the lowest level inside the radio. Of course the Tx is another issue.

Re: [Elecraft] K3 #4951
Jetti, It would seem that you are having a multitude of strange behaviors. The usual thing to try is an EEINIT, but before doing that, try to use K3 Utility to save your parameters (or better yet, have a prior configuration save done before the problems surfaced). Try an EEINIT and restore your parameters from a known good working set if possible - if you do not have a good set of saved parameters, you may have to restore all your settings manually. Things do not go to hell in a handbasket with multiple symptoms unless the data tables get scrambled, and it sounds like you have multiple problems there. 73, Don W3FPR On 12/31/2010 8:34 PM, Jettie Hill wrote: HI SIG on readout.

Selling these WHEN? Oh gak. I've been day-dreaming again.
