Re: [Elecraft] K3 in a cw pileup - needs work
K2AV posted: Using slope 000 is likely most of your problem. With that setting all signals regardless of strength are set to the same level regardless of how loud they are coming in. Actually AGC SLP 015 flattens the audio output. AGC SLP 000 is the minimum AGC action but it still reduces the audio output compared to AGC OFF. If they are zero beat or close, it will mush the dickens out of the copy by making them all the same level in your ear. I set AGC SLP to 15 for contests. This makes a wide range of RF signal levels produce the same audio output level, probably not ideal for contesting. Make sure your ATT/PRE/RFGAIN use conforms to something like: 160m ATT plus RF gain at 2 oclock 80m ATT plus RF gain at 3 oclock 40m ATT plus RF gain fully clockwise. 20m 15m off plus RF gain fully clockwise. 10m PRE plus RF gain fully clockwise. 6m These ATT and PRE settings are generally OK, but band conditions and antenna/terrain gain can alter them. The RF Gain is seldom optimum at full scale.

Re: [Elecraft] K3 in a cw pileup - needs work
The Smiths asserted: Having the Slope set to 000 is like not having the AGC on at all. Not really. AGC SLP 000 still produces significant AGC action. See K8ZOA's paper. There is considerable white space between the Slope=0 curve and the AGC = OFF line. That's why Dave proposed enhancing the AGC SLP parameter with negative numbers.

Re: [Elecraft] K3 in a cw pileup - needs work
During the CQ 160 the K3 performed very well. Also in the (small) pile-ups. Only mushy experience I had the following situation: - Being on the DX cluster - Everybody clicks to you through some bandmap - Therefore everybody calls on exact the same freq No wonder it sounds mushy. (exception: K2's that are mostly more than a few Hz off can be heard :-) ) 73 Arie PA3A __ 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] New Power Supply
Hi Ruben, I use samlex 1223's for many years, mainly on my expeditions and also with K3. You have to know that there are PS's made in BY which look exactly like the original 1223 but they have no output filtering and they have a different 12V connector. They do have a noise issue, particularly on 80m SSB band. I know that these were sold at the Friedrichshafen hamfest a few years ago. There is enough room behind the 12V connector to add some filtering inside. Noise issues can be fully cleared up. I can send U some photos, let me know if you need. Don't worry, 1223 noise issues can be fully cleared up. 73! zoli ha1ag It is also wise to add a varistor to protect your radio if the PS bites the dust.

Re: [Elecraft] K3 Loses RX Audio at BW of 2.8 kHz
I have been noticing a similar anomaly since 3.76. The only difference is it happens when I go to 2.9. As I increase the width I see the filter switch at 2.8 (I have the 2.7 SSB filter and 6.0 AM filter) and then at 2.9 it goes dead until I advance it to 3.0 and from then on it continues as it should. Also when it goes from dead to audio at 3.0 I get a nasty click. Scott, maybe it's a Prather deal.

I've tried an EE-Init and reloaded the configuration, but the problem remains. Thinking this might be related to 3.76, I went back to 3.30 and I have exactly the same problem. If I turn on the sub receiver and change its BW using BSET, it loses LSB, USB and AM audio at 2.8 kHz as well. To get audio to return, all I need to do is change the BW to 2.9 kHz or greater on either the main or the sub. Looking through the reflector postings, it looks like someone saw something similar to this in the DATA mode a few months back, and pressing the A/B key would clear it. However, in my case the only way I can restore audio is to change the BW to 2.9 kHz or greater. In the CW and DATA modes, the audio does not drop out at any bandwidth setting.

Re: [Elecraft] K3 in a cw pileup - needs work
Hi Guy, The problem reported has the classic characteristics of in-passband IMD caused by a small dynamic range (IMDDR3) IF system, rather than being something caused by the AGC sub-system. Yes changing the AGC's loop characteristics will alter the effect, but the root cause is still non-linearity in the signal path. I suspect the second mixer. Trouble is that large IMDDR3 IF systems can consume a lot of power, and low power drain by the K3's receiver was a design goal I believe. 73, Geoff GM4ESD On Saturday, February 06, 2010 at 5:17 AM, Guy Olinger K2AV wrote: Hi Dave, Using slope 000 is likely most of your problem.

Re: [Elecraft] K3 No ATU and 12w max
Tom and All, Sounds familiar! Your K3 serial number is low enough to be one that may be affected (mine is #96) by a problem that is fairly easily corrected. There's a cap that needs to be removed (if it hasn't been already, and another small cap that needs to be added. I see you have copied Gary Surrency, and he will undoubtedly supply you with the complete details (if I am right about the issue). If this happens again in the meantime, try this--disconnect the K3 from all power, and let it sit for a while. It may have to remain disconnected for a while. Chances are that this will temporarily restore your ATU. Sometimes I had to wait 30 minutes to an hour before this worked. After I made the mod, the problem has not returned, so I think it is solved. Since it is the weekend, you might not hear from Gary until Monday. I can send you the info he sent me, but I'm assuming it's the same problem. The cap that needs to be removed is C19, and the cap that needs to be added is an SMT cap (300 pf I think). You just tack it across two pins on an IC. Let me know if you need the info.

Re: [Elecraft] K3 NB and Digital Reception
Hello Julian, I also noticed the other day that I was hearing a whoosing in the background on a CW station that I never heard before. I was afraid I had blown a preamp or something. I finally found that I had set the NB on Wide 7, and as soon as I turned it off or back to Nar 1, the problem disappeared. So something must have changed in the NB operation in the latest Firmware. I also found last weekend when I switched to 144 MHz in the transverter mode for an EME sked, that my audio output from the LINE OUT suddenly seemed to be 15 or 20 dB down on that band, as compared to 6m. That had never been a problem before. I don't know if that is also related to the Firmware version or not. In the last week I also found that the noise level seemed to come up higher and reduce signal strength of incoming signals I use as reference (6m beacons). Anyway, I still use the same firmware version, but I re-loaded a Configuration file that I had saved several months ago...and readjusted the LINE OUT level in the CONFIG menu. That seems to have solved the problems except the one with the NB. Now I have to be very careful not to use the Wide 7 NB setting.

So I switched to another sound card - and still the same result after I had reset the controls again. Then I remembered that I had set the NB on (dsp off) and IF to Wide 7 and as soon as I had turned the NB off, his signal was copied just fine. What I found was that setting the IF to Wide 7, Med 7 or Nar 7 gave rise to what only can be described as intermodulation. The reason I use the NB at all is because my neighbour has one of these solar pads that heats his swimming pool on his roof, and the pumps in it generate this ta-pocketa-pocketa-pocketa noise (like an electric fence, but faster) - and I just leave the NB one most of the time, because my neighbours also own behemoth plasma TV sets :) So two questions: 1) has anyone else noticed spurious intermodulation in DATA mode when the IF NB is set to the 7 level - or have I got a fault?, and 2) Is there a beginner's guide to help me understand how to use the NB effectively - at the moment, I just spin the dials until the noise is gone. thanks, Julian VK4CMV -- Lance Collister, W7GJ (ex: WN3GPL, WA3GPL, WA1JXN, WA1JXN/C6A, ZF2OC/ZF8, E51SIX) P.O.

[Elecraft] K3 Utility program issue
I've been meaning to query the group about this for some time but the latest episode has finally prodded me into asking. I have noted before that when I ran the utility program after closing it and then trying to use my logging program, the log couldn't connect using the serial port. Apparently the utility wasn't releasing the serial port after having used it. Windows Task Manager would not show that the utility was still running, but it would take a reboot to fix the issue. Not only that, but Windows wouldn't shut down normally because it thought the utility was still running and wasn't responding. I would have to tell it to go ahead and close the utility. Last night afte reading one of the threads on this reflector I decided to read the release notes using the utility. The K3 wasn't even turned on and I obviously didn't try to address it with the program. After reading the notes, I closed the program, decided to go to bed, started the Windows shut down and left the room. This morning I came in and discovered that the computer was still up, didn't think much of it until I tried to open the logging program and got the I can't connect to the radio error. So even though I never used it, the utility apparently captured the serial port and I had to go through the whole process of manually shutting down Windows to get back to normal. For the record, I'm running a Lenovo T400 with WinXP Pro SP3 and a Quatech USB-Serial interface. Anyone else have this problem?

Re: [Elecraft] K3 Loses RX Audio at BW of 2.8 kHz
Jeff: Thanks for the suggestion concerning the K3's filter configuration, however, I'd already checked this. According to the K3 Configuration Utility, FL3 is enabled for LSB, USB and AM in both receivers. Another point to keep in mind is that FL3 is only selected at a BW setting of 2.7 kHz or below, FL2 is still used at 2.8 kHz. I just received the DSP board upgrade yesterday and intend to install it this weekend. However, I thought that before I make any hardware changes there might be some value in trying to determine what happened in case the swap-out clears this issue.

Re: [Elecraft] K3 in a cw pileup - needs work
Dave indicates that the problem occurred when the pileup consisted of four or five loud stations. This leads me to wonder if the cause is the K3 hardware AGC threshold being too low, even after the mod introduced two years ago. That mod was supposed to raise the threshold from S9+5 dB to S9+25-30 dB. I got into this issue after repeatedly being botherd by thumping from loud CW stations above my passband during big contests. When I first noticed it, I was using the 5-pole 500 Hz filters and the DSP set to about 300 Hz. I'd hear the thumping from stations more than 150 Hz or even 250 Hz above my frequency. Testing revealed that I could hear thumping from loud CW signals as far as 700Hz away. The testing also showed that the filters were effective against a loud continuous carrier, but CW signals were slipping under the skirts. This suggested that the problem is caused by the hardware AGC being tripped by the loud signals. I switched to 8-pole 400 Hz filters, and that improved the situation considerably. My testing probably wasn't lab-quality, but it showed that the hardware AGC really kicks in much lower than S9+25-30dB. I think it's more like S9, or just above. Perhaps if two or more signals in Dave's pileup were that lour or louder, the hardware AGC kicked in and mushed them together? 73, Dick WC1M -Original Message- From: Dave Hachadorian [mailto:k...@arrl.net] Sent: Friday, February 05, 2010 10:45 PM To: Elecraft Reflector Subject: [Elecraft] K3 in a cw pileup - needs work Tonight I used a pair of K3's in the Sprint practice. Several times I had a pileup of four or five loud stations calling me. With AGC turned on, they were all mushed together, and I couldn't copy any of them. AGC settings: dcy soft hld 0.2 pls nor slp 000 thr 008 f 200 s 020 I tried both fast and slow agc. No joy. So I turned the AGC OFF. Now this introduces another problem - the very low threshold of the AF Limiter. The AF limiter, even at its highest setting of 030 introduces gross distortion on loud signals. This is even worse than the mushy AGC. So I transfer the headphones to the speaker output, so I can reduce the AF gain setting in an attempt to get away from the raucous AF limiter. This works for a while, until finally one loud signal blows out the K3's audio amplifier. This is the second time that has happened to me. I guess I'm a slow learner on that issue. Something really needs to be done here. My suggestions would to raise the agc threshold further, and increase the slope of the agc line (that would mean a slp setting of less than zero). The AF limiter threshold also needs to be raised, and the AF speaker output needs better protection.

Re: [Elecraft] K3 in a cw pileup - needs work
Yes. For non-portable use how about a K3 Pro or K3 MK V++ that clips a few circuit traces and has a daughter board that uses two or three filter slots to house a stout IF amp, an H-mode second mixer and a PIN attenuator before the DSP? The one remaining filter would only have to be good enough to get rid of the image. Just thinking out loud. --- On Sat, 2/6/10, Geoffrey Mackenzie-Kennedy gm4...@btinternet.com wrote: Hi Guy, The problem reported has the classic characteristics of in-passband IMD caused by a small dynamic range (IMDDR3) IF system, rather than being something caused by the AGC sub-system. Yes changing the AGC's loop characteristics will alter the effect, but the root cause is still non-linearity in the signal path. I suspect the second mixer. Trouble is that large IMDDR3 IF systems can consume a lot of power, and low power drain by the K3's receiver was a design goal I believe. 73, Geoff GM4ESD __ 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] K3 Utility program issue
The K3 Utility closes the serial port at exit. Windows process termination also closes open file handles. However the close process invokes device drivers to actually release the hardware, and sometimes that doesn't work as you might hope.

What has worked well for me is AGC off (although AGC on works fine as well), high isolation headphones, and the gain throttling techniques (most important) described by K3NA, W4ZV, myself, and others. 73, Barry N1EU (http://n1eu.com) -- View this message in context: http://n2.nabble.com/K3-in-a-cw-pileup-needs-work-tp4523884p4527366.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Just to continue from previous post - I experienced only mush in pileup reception until fully adopting this technique. High isolation headphones are critical because you want to set gain such that weak signals are lightly heard but clearly copiable. You're maximizing the receive dynamic range delivered to your ears and the high isolation means you can clearly hear fainter signals without turning up the gain and squashing the dynamic range (and too frequently engaging AF Limiter with AGC Off). 73, Barry N1EU -- View this message in context: http://n2.nabble.com/K3-in-a-cw-pileup-needs-work-tp4523884p4527626.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] Field Day Antenna Setup
Ok so far I've only had the pleasure of operating on a gain antenna in the HF bands for 2 days in my lifetime. I'm in the process of working out a setup that will allow me to gain at least one day a year... ;) I'm looking at a mast setup from Blue Sky Masts (http://www.blueskymast.com) From the looks of it they will allow me to get my antenna up to about 10 meters with margin. The antenna that I've been given is a Hustler 3-TBA its rated to provide 8dB of gain. Doesn't specify what band that gain pertains to or if its dBi dBd or what... But its got 8dB of magical happiness. And 27 to 28 dB of F/B ratio. It has a boom length of 14' and a longest element of 24'9. The wind surface is rated at 5.7sq. ft and it weighs 40 pounds. Blue sky has a max head load of 40 lbs at 11 meters on their sturdier towers. This is why I figure 10 meters would be a good number. However I plan on purchasing the 11 meter tower as it is the first model that comes with the secondary guying equipment rather than having to purchase it separately. So my question to you gentlemen is what are your thoughts on this antenna? How high to I really need to get this thing in order to get good performance out of it? I ask this because I heard from the Blue Sky sales guy that he'd only recommend going to about 8 meters and double guying. (I'm still waiting for a response from BlueSky Engineering on why I'm not allowed to use their mast to 10 meters as I'll be doing so with margin). I think the reason may be that their wind load ratings are tested with 1 sq ft of surface area. Then finally if I were later to add a better antenna system to this setup what would you recommend? Preferably more gain as I'm usually running with either 7 watts (K1) or up to 100 watts (K3) never more (and usually less). I think that less weight would also be beneficial as it would make things easier to deploy and might possibly lend itself to greater mast heights (I can always buy more mast sections to add to my setup at a later date). Thanks for your thoughts gentlemen. ~Brett (KC7OTG) __ 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
[Elecraft] Elecraft CW Net Announcement
Good Evening, I try to keep my announcements and reports cheerful and filled with stories about the outdoor occurrences in my area. This week is different. We have lost one of the fine gentleman of amateur radio. On the afternoon of Thursday, February 4th, I got an email headed with W6ZH - SK. I had lost another friend but was reticent to read the email. The feeling of having my heart drop just from a few characters written on a computer monitor had happened again. But I opened and read the note. Even though we had lost Pete Hoover the email was good in its way. He was surrounded by family when he passed on and had lived an exemplary life. One we could all aspire to but never hope to match. Please search the Internet for stories about him and his family. We all are in a very deep debt to his grandfather. The Commerce Secretary saved amateur radio and many of a certain era had their licenses signed by Herbert Hoover. Without his work and passion for what he knew we could do we would have lost our privileges. This passion was continued by Pete and his very charming wife Meredith. Thank you to Pete and to your father and to your grandfather. You will be missed by all that ever met you. Could we please dedicate tomorrow's two nets to Pete Hoover? Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Sunday 2300z (Sunday 3 PM PST) 14050 kHz Monday z (Sunday 4 PM PST) 7045 kHz Stay warm, Kevin.

Or was I dreaming :) You were not dreaming! The K2 will treat a simultaneous contact closure of both the dot and the dash lines as a straight key. The two diodes are there to eliminate the short circuit that would otherwise exist between the two sides of the paddle, which would cause a contact closure on either side of the paddle to ground both sides (and therefore be treated as a straight key as well). The circuit is on page 95 of the K2 manual. There is also a menu item that you will need to ensure is turned on. 73, Brian VE7NGR __ 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] K3 Loses RX Audio at BW of 2.8 kHz
My K3 was working fine last time I used it. Tonight I turned it on and noticed a similar problem -- no audio in USB or LSB modes whenever I set the width to 3.00 kHz or less. Tried downgrading from 3.76 to 3.63 but no change. Checked all filter settings in the config menu, nothing out of place. All other modes were fine. On a hunch, I restored my last configuration backup file. It worked! Everything seems to be behaving well again. 73 de WW2PT On Feb 6, 2010, at 12:45 AM, Scott Prather wrote: All: This evening when running FW 3.76 I'm seeing a problem with my K3 that I've never seen before. When the K3 is in the LSB, USB or AM mode, adjusting the bandwidth down to 2.8 kHz will result in total loss of audio, even though the S-meter continues to read incoming signal strength. I've tried an EE-Init and reloaded the configuration, but the problem remains. Thinking this might be related to 3.76, I went back to 3.30 and I have exactly the same problem. If I turn on the sub receiver and change its BW using BSET, it loses LSB, USB and AM audio at 2.8 kHz as well. To get audio to return, all I need to do is change the BW to 2.9 kHz or greater on either the main or the sub. Looking through the reflector postings, it looks like someone saw something similar to this in the DATA mode a few months back, and pressing the A/B key would clear it. However, in my case the only way I can restore audio is to change the BW to 2.9 kHz or greater. In the CW and DATA modes, the audio does not drop out at any bandwidth setting.

I agree with Brian, this arrangement works quite well, although I use a pair of 1N5821 Shottky diodes in place of the 1N4148 and have also wired a 0.47uF (474) capacitor across the straight key. Without the capacitor I got unpredicted errors, possibly caused by stray r.f. in the shack. My only regret is that the K3 does not have a menu option to accept my K2 dual key assembly. Consequently, I have to use a different key for the K3. 73 -- David G4DMP Leeds, England, UK -- __ 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
