[Elecraft] Re: K3 suggestion for future release - Band Skip
I believe your asking for something that the Yaesu FT-2000 does - enables you to choose the bands you do use and skip those you don't (for whatever reason, no antenna, don't like, not open). I agree might be a useful feature for some future update (I'm just keen to get my K3 in early Aug). If Elecraft do add this, I would hope it only skipped bands found via the UP/DOWN buttons. On 5/7/07 09:03, [EMAIL PROTECTED] DOUGLAS ZWIEBEL [EMAIL PROTECTED] sent: HOW ABOUT ADDING THIS: When using the band up/down button, enable a feature that allows to SKIP certain bands. I am thinking contesting. For example, to get from 10 to 20, using the Band Up/Down would take 4 pushes. If you know that you won't be on 12 and 17 (cuz it's a contest) and you could disable them (or skip them, whatever you want to call it), then it would only take 2 pushes of the Band Up/Down button. -- Accuracy Transcends Speed ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Toroid Winding Question
Perhaps this question has been raised before, but I haven't been able to find it in the archives nor in the manual. I've built a K1 (words fine) and am now building a K2. Yesterday, while finishing one of the first toroids in kit, I noticed one of the turns had crossed over the previous one, so I began to unwind it. Then I noticed that the wire had the enamel nicked in several places and chose to replace it. In thiking over what might have happened, wondered if I may have been pulling the winding too tight. Currently, I'm pushing the wire through the center of the core rather than pulling it so as to keep it away from the core to minimize scratching it. Obviously, though, it's not possible to know if the winding has been scratching in making the bend around inside. So, my question is, to quote Shakespear, is my concern much ado about nothing? Am I winding them too tight (I noticed there are LONG leads after winding that could indicate the turns are too tight)? 73 de Clark KE4RQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Toroid Winding Question
In my case, I wound them tight, and reduced the amount of wire used so I did not have so much extra after the torod was done. Some cores scrape the wire, I tried to use a bit more caution but still had some scrapes, it does not matter, they don't short out. I wound all my toroids with one extra turn, as the first pass through the core counts as a turn (I did not know that), the rig actually seemed to work better before I unwound one turn off every toroid and re-did the alignment/calibration. I would doubt the tightness makes much difference other than looks, as one turn more or less did not seem to make any big difference in my K2.

Re: [Elecraft] Toroid Winding Question
Clark, Scraped wire can lead to shorted turns. The core is not conductive, but if adjacent turns short to one another, failure will result. You are doing it right by pushing the wire through the center rather than pulling it. To keep the turns tight, dress the wire around the outside of the core with your finger, then push the wire through the center until a small loop remains - you can then snug the turn by pulling it the rest of the way through and no scraping should result. Those ferrite cores do have sharp abrasive corners - it is the nature of ferrite cores and one of those things we have to deal with. The powdered iron cores have smooth corners and do not create the scraped enamel problem. 73, Don W3FPR Clark Macaulay wrote: Perhaps this question has been raised before, but I haven't been able to find it in the archives nor in the manual.

Re: [Elecraft] Toroid Winding Question
Not sure about hand sanding, but i know grinding ferrite is a tricky process, I haven been designing flyback transformers of late and grinding the gap in ferrite cores has resulted in many cracked and broken cores, i would assume if you are meticulous and careful hand sanding is probably ok.

Re: [Elecraft] Toroid Winding Question
Hi Kevin: Probably more effort than it's worth. I have tried running a 'beveling' drill bit around the inner edges, and several other schemes, but not sure it's much help. For the relatively few ferrite cores in the kit, I would urge the careful application of restraint while winding and not worrying about it from there on. We hear very little(!) from builders regarding actual problems from shorted turns, so it's obviously not a significant problem... other than a source for worry for some builders. If it were a bulldog, his bark would be worse than his bite!

Re: [Elecraft] Toroid Winding Question
Kevin, I have not tried it, but I believe the ferrite material is harder than the 'wet and dry' paper. All in all, I do not believe any prep work on the cores is worth the effort. Just remember to *push* the wire through the center rather than trying to pull it through. Using your finger to form the wire around the *outside* of the core as each turn is placed will result in a neater and tighter winding than all the pulling in the world. Try it on 2 toroids - then wind your 3rd - after that you too can call yourself an expert. Many folks seem to have some anxiety about toroids until they have wound some. It is not necessarily the most pleasant task, but it is really easy - just do it. If you have a long wire to deal with, start in the middle, wind half the turns and turn it over and wind with the other half. As soon as you put a wire through the center of the core, start counting - that is one turn. One full winding around the core is two turns. 73, Don W3FPR KBG Luxford wrote: With respect to toroid sharp edges, should one rub some wet and dry abrasive paper around the edges before winding?

N6TR: Simply put - this is a great radio. I can't wait to get a second one so I can fully move my SO2R station over to them. KR2Q: A bit vague, but I'll take what I can get. Considering the source this is an outstanding endorsement! Tree N6TR is one of the best SO2R ops in the world. He often wins the NCJ CW Sprint which is probably the most difficult contest in the world. It's a 4-hour event where you must QSY at least 5 kHz after working anyone answering your CQ, so it is a true test of rig and operator agility. If my memory is correct, Tree holds the QSO record with something like 425 QSOs. Tree is also the author of TR Log so he also knows how rigs should interface to computers. Tree is also very understated. You won't see a lot of superlatives in his comments but you can be assured his comments mean that the K3 is not plagued with poor ergonomics or serious firmware issues, even at this early stage of beta-testing. Congratulations to the entire Elecraft K3 team for an outstanding endorsement from one of the best contest operators on the planet! 73, Bill W4ZV P.S.

Re: [Elecraft] Toroid Winding Question
Hi, Kevin- Some of the ferrite cores can be a bit rough around the edges. When I encounter a batch that exhibits this characteristic, I use a drill-bit to clean up the burr prior to winding. Pick a drill-bit of a size substantially larger than the toroid's inner diameter, and spin its tip back and forth a few times in the toroid's hole. You should fine that the burr comes off easily. I don't usually have trouble with the OD of the toroid, but in that case you could use some fine sand paper. 73, Mychael / AA3WF K2 #1025 With respect to toroid sharp edges, should one rub some wet and dry abrasive paper around the edges before winding?

[Elecraft] K3 Question
K3NG: can I expect comparable or better CW performance to what I have with my Kenwood 850 with a 500 Hz crystal filter? Probably better but you need IMD performance at 2 kHz spacings using the stock 2.7 kHz filter to answer for sure. Sherwood Engineering measured the TS-850S with dual Inrad 400 Hz filters (in the 8.8 MHz and 455 kHz IFs). At 2 kHz, IMD was 77 dB. Considering that this is with a 15 kHz roofing filter in the 1st IF of 73 MHz, I suspect the K3's 2.7 kHz filter in its 1st IF of 8.125 MHz will be substantially better. Using the optional 400 Hz filter in K3, we have already seen the following hints from Elecraft: N6KR: But just to give you a hint: a couple of days ago Eric measured a blocking dynamic range of 143 dB, and it remained 143 dB at 20 kHz, 5 kHz, and 2 kHz. To put this into perspective, the K2, IC-7800, Orion II, and FTDX9000all have a blocking dynamic range of -133 to -135. WA6HHQ: As an example, we're seeing third order IMD D.R. numbers on 20M at 20 kHz spacings in excess of 104 dB and 97 dB at 5 kHz with the 400 Hz filter ahead of the DSP. (de W4ZV - Orion II is 95 dB at 5 kHz) Plus, when N6TR says he is replacing both of his TS-850s with K3s in his SO2R setup, you can probably take that to the bank! 73, Bill W4ZV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 10m is open
Jacques, Have not been able to check 10m this past week, but some good but brief 10m multihop Es openings to the west the week before in among the Europeans. VE9AA worked G7CNF 6m - 4m crossband on June 26th via multihop Es. FWIW my bet is 10m F layer openings in 2 -1/2 or 3 years time!! 73, Geoff GM4ESD - Original Message - From: f9oj.7 [EMAIL PROTECTED] To: Ron Polityka [EMAIL PROTECTED]; .Elecraft elecraft@mailman.qth.net Sent: Thursday, July 05, 2007 3:21 PM Subject: Re: [Elecraft] 10m is open Hi Lots of European stations here in Europe, but not too many DX stations, unfortunately.

Re: [Elecraft] k2 question
Frank The K2 tuning experience is smooth, but a bit different. The K1 is continuous tuning with an LC oscillator. The K2 uses a sort of synthesizer, in that the tuning goes about 5 kHz then there is a tick as the internal works switches to the next 5 kHz range. For all practical purposes, it is continuous tuning. An advantage to the K2 tuning is that you can change the tuning rate from the front panel. Mine has three different tuning rates which I just love. 73, Bob N6WG - Original Message - From: Frank [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Thursday, July 05, 2007 5:33 AM Subject: [Elecraft] k2 question K2 users, I'm thinking about building a k2 for myself.I built the k1 and do use it.Is the VFO operation better than the k1?

Re: [Elecraft] Toroid Winding Question
You can reinsulate the wire by painting it with clear nail polish. In fact, the cores are not a concern as they are an insulating material. The bare wire touching the core is not a concern, a bare wire touching an adjacent winding is what to avoid. You do not have to have the turns pulled so tight against the cores that you are abrading the insulation. Gently pushing or pulling them thru should be fine. I sometimes make my cores look better by pushing gently on the winding to make the wires lie more flat against the core. This is safely done with the fleshy part of the thumb.

[Elecraft] Trade Ten Tec Jupiter towards a K2/100
I have an excellent condition Ten Tec Jupiter with the remote tuning knob that I would like to work out a trade towards a late serial number K2/100. I am going to go with Elecraft for my HF equipment. (also patiently waiting for my K3) The Jupiter looks and works great, has the factory shipping container, power cord and manual. It does NOT have the internal tuner. Has the latest firmware installed. Please email with details if interested. Probably not many on this list interested in this trade, but there are a lot of K2/100's here.. :) Thanks Tim NZ8J ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Zero Beat WWV
Ok, totally confused by the zero beat to WWV. I can zero beat an un-oscillated WWV carrier at two points, in USS and LSB. When they add the odd-hour 600hz tone, things become even more confusing. I suppose I am relagated to obtaining a spectrum analyser, but which mode should I use to zero beat when I do so? USB, LSB or CW? Killing me here...

Re: [Elecraft] Zero Beat WWV
Joe, Let me see if I can help. First I usually think of 'tuning WWV' rather than 'zero-beating' just to keep my mind straight - I leave the Zero Beat term reserved for CW use when you want to tune the desired signal to match your sidetone pitch. Tune WWV in using LSB or USB because the K2 does not add an offset for LSB and USB. There are 3 ways of doing it: 1) Tune the carrier to an audio frequency of zero (which you cannot really hear, but go as low as you can) and refine it by tuning until the voice announcements sound 'natural'. 2) Understand the sequence of tones transmitted by WWV - for the most part they alternate between 500 and 600 Hz on alternate minutes (there is also a 440 Hz tone transmitted one minute of each hour). Set your sidetone pitch to either 500 or 600 Hz and use the SPOT on the K2 to match the transmitted tone at the correct minute. Or 3) My preferred method is to use Spectrogram (yes, this is an audio 'spectrum analyzer') and feed the K2 audio into the computer soundcard input - with Spectrogram set up properly, you will be able to see the transmitted tones on the Spectrogram display, set a marker in Spectrogram to 500 Hz and another to 600 Hz and watch the display to be certain the tones alternate between those two markers - when they do, you are accurately tuned to WWV. I find this is the easiest method for folks like me who have trouble discerning the pitch of a tone - if you are a musician and have 'perfect pitch' you will not likely need such a visual aid. You can download the last freeware version of Spectrogram from Tom Hammond's website www.n0ss.net. If you need some information on how to set up Spectrogram, read over the K2 dial calibration article on my website http://w3fpr.qrpradio.com - the latter part of that article (CAL PLL) has information and links to setting up Spectrogram. 73, Don W3FPR joey mcg wrote: Ok, totally confused by the zero beat to WWV.

Re: [Elecraft] Zero Beat WWV
They turn off the tone modulation every hour for a bit. See their schedule for time of this. That is the time you do your most accurate zero beating, and in CW mode of your receiver.

Bounce back and forth between LSB and USB (hold down CW RV for a second to quickly switch), adjusting the frequency until the tones WWV transmits sound the same in both modes. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
