[Elecraft] K3 Relay Noise
I am probably am just hearing "things", but for some time I have heard what sounds like a relay switch, just once, in my K3, #1292, while it is powered off. Is there anything that would be still powered and "busy" while the K3 is supposedly "OFF" that could be doing this? I have no other equipment in the area, and my ear is only about 18" from the K3 when I hear it. Anyone else hearing this? This morning when I heard this noise the K3 had not been powered "ON" since last night. I power all my radio equipment with solar charged batteries, FWIW. 73, Ken, NU4I __ 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] OT: Digital Signals on 20M
For the past several days I have been seeing a couple of powerful digital signals, S9+, between 14.018 to 14.032MHz. They seem to be comprised of 4 or 5 discrete frequencies rapidly moving around in a bandwidth of about 2Khz. When working with a narrow filter it is possible to work through them, with difficulty. With a wide filter, 2.8KHz set to the center of their bandwidth it sounds like a group of castanets clicking away with slightly different tones. I might have just discounted them but for the fact that I have just recently gotten a "poor man's" panadapter using a Rockmite and Z1 amp from Clifton Labs with the Rocky software monitoring my K3's IF output. These two signals have been here every time I get on 20M and are quite impressive in the amount of bandwidth they occupy. I have not seen this on any other band. Forgive my ignorance of digital modes, but I just don't recall hearing this sort of signal before. Can anyone let me know what this might be?

[Elecraft] Use of PC power supplies with K2
I would like to hear from anyone who has attempted to use one of the small external PC AC adapter power supplies with a K2. They are, of course, switchers, so I am not very hopeful. I have found a couple of possible candidates, one a Meanwell P40A-4PSJ rated at 13.8 volts at 2.66 amps and the other an APS AD-740U-1138, rated at 13.8 volts at 2.8 amps. They seem to have somewhat comparable specs as to regulation, ripple, and protection. I suspect they would be pretty bad on RFI, so even though they can be had cheaply, they may not be worth the grief. My fallback position would likely be the little unit from Gamma Research, HPS-1a, but that will be twice as heavy and probably ten times more expensivebut from what I've read about it, it is not very noisy electrically. I would really appreciate any thoughts, especially those with first hand experience. This would only be for portable operation, not "normal" use. Thanks. 73, Ken Moorman, NU4I __ 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] Use of PC power supplies with K2
Thanks John, I should have stated that this would be the K2/10. These little switchers are the sort that powered laptops. They are sealed units with single output voltages, not the boxes that go into the desktop machines with multiple output voltages. I should have been clearer about this. Ken, NU4I My summary comment would be that power supplies run the gamut wrt RFI problems, and that one might well have to proceed by trial-and-error. I have always rejected use of the PC-type power supply because they usually come with a spaghetti of different wires intended for different functions within the computer. The small Radio Shack 25 amp supplies are about the same volume as a typical PC supply, and a great deal more congenial (cosmetically) than the latter.

[Elecraft] K3 in AM-Sync Mode Receiving WWV
I have been trying out the new AM-Sync mode by listening to WWV on its 5 frequencies and am seeing something that I wonder is a "problem" for my K3 (#1292) or is it being seen by others as well. I have observed that on the 10MHz WWV frequency only, that my K3 will momentarily "unlock" with the frequency jumping either up or down by as much as 200 Hz. The frequency quickly, less than a second, will be corrected, and all is well again. This occurs at what appears to be entirely random timing, from several minutes, to as often as a few seconds. I haven't noticed this happening on any of the other WWV frequencies that I have observed, being all of the rest except 2.5MHz which is not open to me this morning. I did notice this yesterday on 10MHz, but did not check the other frequencies until today. I find it difficult to believe that WWV is having "jumps" in its 10MHz transmission. Has anyone else noticed this, or do I need to be giving Elecraft help desk a call?

[Elecraft] Using K2/100 on QRP
I have the K2/100 with the KPA100 and KAT100 mounted in the separate EC2 enclosure. I would like to use the K2/10 in a portable situation independently, leaving the 100 watt components here in the shack. I have no concern with the uncabling part of the operation, but I am wondering if there is some menu item(s) I must reset after getting the K2/10 separated from its high-powered components. This is the first time I have contemplated such operation since obtaining the amp/tuner about 18 months ago, and I can't remember what if anything I did to the menu items to get both "boxes" working together. I feel sure that this has been done by many folks who can quickly set me on the right path.

RE: [Elecraft] Suggestions for KDSP2 Firmware Revisions
I agree with Jeff that the KDSP2 is awkward to use. I will admit that it is my first and only experience with a DSP, so maybe this "comes with the territory". I tend to just leave mine on all the time, as I haven't committed the button push cycle to memory yet. It would be nice to have "Bypass" cycle with the DSP bandwidths as Jeff has proposed. Ken, NU4I -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Sent: Wednesday, June 06, 2007 8:37 AM To: Lyle Johnson; elecraft@mailman.qth.net Subject: [Elecraft] Suggestions for KDSP2 Firmware Revisions The KDSP2 DSP filter for the K2 works great, in my opinion, but I wonder if it would be possible in a future KDSP2 firmware revision to implement some or all of the following three suggestions, which would increase my CW operating convenience: 1. Reduce the number of button presses necessary to put the KDSP2 into bypass mode (turn it off). Currently, it takes a button tap, two button holds, and one more tap to turn it off, if you just turned on the rig, and two button taps to turn it back on. I find that the two button holds are the most time-consuming and bothersome parts of the process, so my suggestion is that the number of button presses to turn off the KDSP2 could be reduced to two taps and no holds by making the "dSP On / bYP" menu entry *always* come up first when the DSP menu is accessed. 2. Make the KDSP2 remember whether or not it is in bypass (off) mode, so that its state would not change when power is turned off and on. That is, the KDSP2 would not have to always be on on power-up. 3. Make the KDSP2 remember the currently selected DSP filter (CF1, CF2, CF3, or CF4), so that the same filter would stay in effect when power is turned off and on. Currently, the rig seems to remember the selected crystal filter, but not the selected DSP filter, when power is cycled off and on. I like to put the KDSP2 in bypass mode when tuning around the band in order to have a wider passband, so I can hear what's going on around me. It appears that the maximum bandwidth of the KDSP2 in CW mode is 800 Hz, which is too narrow for my taste when tuning around. Once I stop tuning and focus on a particular signal, I often turn the KDSP2 back on to eliminate QRM. This habit results in my having to do a lot of button pressing to turn the KDSP2 off and on repeatedly. Also, when I turn the rig on, I'm initially turning around, so I want the KDSP2 to start out in bypass mode, but it defaults to on, even if I had it off when I last used the rig. Another advantage of being able to easily keep the KDSP2 turned off is that having it off reduces power consumption. When operating portable from the internal battery, I would like to be able to make the KDSP2 stay off until I return home, rather than having to turn it off each time I power-up. As an alternative to suggestion (1), above, a slightly different setup that would make me happy would be the addition of a fifth state, bypass, when the K2's AFIL button is held repeatedly. That is, after cycling through the four DSP filters (CF1-CF4), the fifth setting would be bypass mode, in which the KDSP2 would be turned off, and next would be CF1 again, and so forth. Another alternative to suggestion (1) would be to increase the maximum DSP bandwidth in the CW mode to equal the maximum bandwidth of the crystal filters (2.49 kHz, I think). If one of the four DSP filters could be set to a very wide bandwidth, then invoking this filter would have approximately the same effect as turning the KDSP2 off (except that it wouldn't decrease power consumption). Do others agree that some of my suggestions would be improvements or are you happy with the KDSP2 just as it is? Please let Lyle, KK7P, know your preferences, as I believe he is the KDSP2's designer, and please let me know too.

[Elecraft] Spurious tone on K2
I have K2 #4456 that is generating a tone starting at 14360.66 kHz and ending at 14365.65 kHz. The tone is adjustable by both AF and RF gain controls, is not a function of which antenna is selected, or any antenna connected. It is steady in amplitude at 30 db over S9, and gradually rises in pitch as the receiver is tuned through the range stated, starting about 800 Hz to probably over 1 kHz. The K2 is equipped as follows: KSB2, KNB2, KAT2, K160RX, and KAF2. Does anyone know what this is? I have not closely re-read the manual, but I don't remember anything about this sort of spurious output over such a range of frequencies. The unit seems to be operating just fine in all other respects.

[Elecraft] T1 ATU used in attic environment
Hi All, I am considering using my T1 to tune a couple of attic antennas, a 40 mtr dipole with drooping ends, and a horizontal loop of about 130 feet total length, as close to the feed point of each antenna as possible to reduce losses in the coax from shack to attic. I would plan to use a relay to select between the antennas, the placement of same which would keep the coax length to about 6 feet after the relay to one antenna, and zero feet to the other. Directly prior to the relay (toward the transceiver) I would place the T1. I would use a small reed relay mounted in a pill box or something similar, to plug into the external tune jack on the side of the T1 to initiate the TUNE cycle, and observe the SWR on a separate SWR meter in the basement shack to know when the tune-up is finished. My concern is the heat buildup in the attic during our hot, sticky Virginia summers. Has anyone else tried to do this, and how did the T1 take the heat? It's a great little tuner, but I doubt it was designed to take 120+ degree heat for extended periods. Any thoughts and observations will be appreciated. BTW, 10 watts from my K2 will be the max expected power for this setup to handle. 72, Ken, NU4I ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] T1 ATU
I tried to use my Elecraft T1 ATU this weekend at a special event station outing on Jamestown Island, VA as an adjunct to the main station. I used my NC2030 on 20 mtrs, and ATS-3 on 40 Mtrs, both about 5 watts output, or that was to be the plan. The antenna was pretty poor, an end fed wire of roughly 100 feet sloping from about 10 feet up to about 30 to 35 feet, with about 20 feet of counterpoise wire under it. I used a BNC to banana adapter on the antenna output of the T1 with the antenna to red, counterpoise to black. Initially the T1 tuned this wire on 20 mtrs to an SWR of 1.0:1, according to the Info function of the T1. I made one contact on 20 to a station in FL, but the band conditions weren't too good at the time, so I switched over to 40. The tuner refused to tune this situation. It would not even start a tune cycledead silence, no relay activity. I tried different frequencies on 40 with same luck, and now the Info function of the T1 showed an SWR of 9.9:1. I went back to 20, but this time it refused to tune here either, stuck at 9.9:1 SWR. So I packed it all up for the day. When I got back home, I tried the T1 with the ATS-3, and my K2 in CAL S mode, and it tuned up the dipoles and loop antenna here just as always, first time. My question is, if the SWR of the random wire in the field was so high that the T1 couldn't handle it, would it not even attempt to tune it? I would have thought it would have searched around for some time, then stopped at it's best shot. Does this T1 sound like a normal one, or is there something intermittent going on with it? Just hoping someone out there has had a similar experience and could offer a bit of advice on what's going on.

Re: [Elecraft] 10.118.288 dead carrier
It's S9+5dB here in coastal VA and seems to be loudest from my NE quadrant as I use my K9AY Loop to receive it. Using CW Skimmer to observe it I can see some sort of rather deep drops in the received signal lasting only several milliseconds that is not related to any QSB. I also see upper and lower sideband info that is about 100Hz or less which seems to be also present at times. 73, Ken, NU4I -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike Flowers Sent: Tuesday, February 16, 2016 1:57 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] 10.118.288 dead carrier Yep - I hear it too.

Re: [Elecraft] A K3 Pileup Wrinkle with CW Skimmer
I use it this way too, and agree it is very helpful.

I'm using it with an LP-Pan in what Skimmer calls the Softrock-IF mode. One rub, though, is that the pileups are so wide that it often is not possible to go split, listen on VFO A, and transmit on the second VFO,. because Skimmer tracks VFOA and the action is too far above K1N's frequency to display on my monitor. My K3 has the separate subRX, happily, so I can invert things - listen to K1N on VFO B, while tuning up the band on VFO A looking for the last successful caller.

[Elecraft] KPod "Memory Helper"
I have had my KPod for several months and have enjoyed using it to save having to use knobs and pushbuttons on my K3 and keeping my hands nearer the keyboard and paddles. But I have had a problem remembering which KPod buttons perform which functions. Cheat sheets just seemed to get in the way or get lost so I wondered what I could do to make my KPod more user friendly. I made the following modification to my KPod to put the name of each used function directly beside the buttons so I could quickly find what I wanted to do, and made it very easy to change the function names as I reconfigured the device. The links below show a couple of views of what I did. Basically, using some double sided pc board I fashioned a couple of "wings" that I eventually attached to the existing device using the screws that help hold it together at its top face. After shaping and drilling the pieces, I soldered the pieces together to form each "wing", spray-painted them, glued into each top face on each "wing" two small rare-earth magnets. Then I made two plastic cover plates the same size as the top faces, drilled and mounted two more of the magnets taking care to get the poles correct with the lower ones in the wings. Then I typed up a couple of label sheets, placed them on the top faces of the wings, and placed the plastic covers over them to finish the project. It makes a very neat way to easily locate and reconfigure the KPod functions. If anyone has more interest in this I have several more pictures of the way I did mine but I'm sure this idea could be fashioned in many ways from other material you may have at hand. https://www.dropbox.com/s/at0urhx9vehxzxr/IMG_5813.JPG?dl=0 https://www.dropbox.com/s/5o8w7rqagtcipn2/IMG_5811.JPG?dl=0 73, Ken, NU4I __ 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 Message delivered to arch...@mail-archive.com

Ken, NU4I -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Locher Sent: Tuesday, September 04, 2007 12:17 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Major Flaw in the K3 I have found a really major flaw in the K3. It can be fixed with an accessory but it will be very expensive. The flaw can be a great frustration. Fortunately, I have been able to fully document what causes it. Here it is - the receiver hears entirely too well. I am hearing all sorts of DX, particularly on 40 and 20 meters, where I spend most of my time. I am hearing a lot of rare DX stations that no one else is calling. The frustration is that when I call them they can't hear me. Often not at all, while at other times they try to get my call but do not manage it. Just because they are S0 or S1 in the K3 is not an excuse; they are solid Q5 copy. This is not a single isolated incident; this has happened to me repeatedly. Of course, once these stations have K3's the problem will probably go away; then they will be able to hear me. But in the mean time this issue must be dealt with. I see two possible solutions. One is to turn off the receiver preamp and turn on the attenuator that Elecraft has so thoughtfully provided - this makes me suspect that Wayne knew all along that this would be a problem - the other is to add a 1500 watt solid state linear with built in antenna tuner and full QSK. I suspect that this is the fix that Eric has in mind. 73 Bob W9KNI ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] PLL Control Voltage Range
I have been having some flakey operation with the main receiver in SN 1292 recently which I believe I have cured for the moment by re-calibrating the main VCO. As suggested in the manual, I have been observing the PLL control voltages on the VFO B display. Depending on the band, it is varying from a low of about 1.5 volts to about 5.1 volts. I also notice that there is sometime a rather large difference between the PLL1 and PLL2 control voltages (about 2 volts) on a given band, but not in all cases. These voltages do not change much over several tens of KHz tuning on any given band. Do these values and actions sound reasonable? I don't recall seeing a table of acceptable PLL 1/2 control voltage ranges by band.
