Re: [Elecraft] Microphone Qusestion [Thread CLOSED]
Yup, its certainly is a valuable thread, but once the volume gets too high, we ask that further discussion be taken off list as we have thousands of readers and not all are able to handle excessive email on topics they are not interested in. Also note that this type of discussion is a repeating topic over the years and can be easily found and read in the searchable Elecraft archives at Nabble.

Re: [Elecraft] Windows 8.1 tablet power
You should be looking for a USB-C docking adapter. It supplies power for charging and extends the USB for devices to connect. They are relatively new - there aren’t that many USB-C systems out so far, so you should expect them to be somewhat expensive. But, the adapters are available. I know that Apple sells one for their MacBook, which uses USB-C. Might be a good starting point, but keep looking to find what you really want. A standard USB hub will not provide what you need... 73, Jack, W6FB On Jul 7, 2015, at 8:57 AM, Mark N2QT via Elecraft elecraft@mailman.qth.net wrote: Actually the issue is the tablet is able to supply power to external devices, which must be disabled when the unit is being charged from an external source.

When replying to emails on the list, please remember to edit down the copied text to the minimum needed to retain context. One or two sentences from the original post are usually sufficient. This keeps the list and archive volume down and makes everything much more readable. *** Don't forget to delete the list footer message too or you will have multiple copies of it in your reply.

[Elecraft] Elecraft email List Official Guidelines 2015 - Updated
Elecraft eMail LIST GUIDELINES 2015 For those of you who are new to the list, (and for those of us who have rapidly failing memories) here is a quick list of things to remember when posting to this list. Please save this for future reference. The most important thing to remember is that this is a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a polite and enjoyable forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share experiences using our products, troubleshooting ideas etc. The Elecraft email list server (reflector) is provided to further the discussion of Elecraft products and related items. It serves as a forum for the discussion of both technical and operating topics including product features, construction and debug problems, sharing your enthusiasm and impressions from using our products and more general ham radio related topics of interest to our customers. (Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 posts. Once it hits ten posts do not reply at all (go off list if you feel the urge to continue.) Also, please do not try to always get the 'last word'.. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft@mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1...@arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w...@arrl.net from your physical address of j...@aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and sent to you each month). 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Top posting is the official standard for this list, and its especially important for those of us who also read our email on smartphones, iPads etc. Scrolling though a long thread before getting to the reply text is difficult on these devices and costs everyone a lot of time. Reading the response first, at the top, is a huge time saver, especially when you have to read hundreds of emails daily as we do here. We really appreciate your adherence to this. Please also delete -all- footers and as much of the prior email text as possible when replying to cut down on overall email size. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the Nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With thousands of list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building, using and troubleshooting their rigs. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line.
[Elecraft] FS: 10w 6m amplifiers
I recently became aware of a source of quite a few Yaesu FL6020 linear amps. I have three that all look in new condition. This coming out of an estate of a recently sk ham up here. All three tested with up 15w saturated output with about 1.5w drive. Nominal 1w provides 10w which is advisable for modes like FM or digital, and for SSB to avoid overdriving. I was able to get a manual and schematic for the amp to ID the three spring-loaded contacts. Two are associated with ALC and one is the TR ckt which takes +13.5v. These amps were a clamp-on option to the Yaesu FT690R (2.5w) that was produced in the 1980's. I'm using one to provide full drive for my 150w 6m Mirage amp (needs 10.5w). Both my K3/10 and KX3 only provide 8w on 6m which drives my Mirage to a tad over 100w (tad = 1-2w). I left the ALC terminals unconnected. I am selling the amps (tested) for $10 plus shipping which is about $10 via priority mail (to USA). I have one at the moment but more available in Anchorage (which I would have to have shipped down to me). I'm waiting on that until I see if there is any interest for them. 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Elecraft Digest, Vol 135, Issue 8
Just a gentle reminder: the vast majority of issues are not in the Elecraft equipment. Great gobs of personal time and frustration are saved by looking FIRST to the mechanical, then third-party adjunct programs, then to the manual (I know, I know, everyone HATES to read the manual). If you are new to Elecraft equipment, then the order is FIRST to the manual, then to the mechanical, then to third-party adjunct programs. Get a PDF copy of the manual, so you can use the search facities of the FREE Adobe Reader to find stuff quickly in the manual. Suffer with the manual for a few months. Ignore the headaches, PTSD, bleeding from the ears, and mental illness issues reading the manual may cause. They are temporary and will go away in a few years. If you think about it, the K3 firmware has been undergoing continuous high stress field testing and bug-fixing since 2008. Should one really reasonably expect the K3 firmware to be sloppy at this point? Good luck on all your issues, and may you please figure them out quicker than I do :) 73, Guy K2AV.

Re: [Elecraft] Windows 8.1 tablet power
Actually the issue is the tablet is able to supply power to external devices, which must be disabled when the unit is being charged from an external source. Best I can tell in some devices The direction of power is either negotiated by a digital message upon connection of an external device or by shorting or opening the data lines when the unit is to be charged. It looks like Dell tablets can operate with specific adapters but there is no guarantee this would work on another brand (and lots of review comments saying it doesn't). This was all a surprise to me, I just figured I could hook things up and go. Mark. N2QT On Jul 7, 2015, at 11:50 AM, Tom tom...@videotron.ca wrote: Hmm, that's interesting.

Re: [Elecraft] K3 KBPF3 mod for LF questions capacitor size ?
They're 0603s (.06 x .03), which would be considered mediums size by today's SMD standards. But it does take a bit of courage (and a good pair of tweezers, and maybe a shot of cheap whisky) to install them by hand. Hats off to our intrepid customers attempting this for the first time! 73, Wayne N6KR P.S. Our engineers and technicians routinely work with with packages that are about 0603 size, but have *6* leads that must all be soldered. This is done by flowing solder onto all 3 pins on one side at a time (carefully!), then wicking the excess solder off with solder wick or a vacuum tool. Not for the faint of heart.

[Elecraft] Observation on new Synthesizers for K3
Hello, I had what I believe to be a unique opportunity to test the new synthesizer in a high signal level environment, under some controlled conditions. K7OLN lives about 750 feet from me, and we both have static antenna setups, and because he is running WSPR K7OLN also has static power levels for these tests. The three test states are as follows: 1. The first P3 capture is K7OLN's K3, using the old synthesizer, as received on my K3 using an old synthesizer. 2. The second P3 capture is of K7OLN, using the same equipment on both ends, save the new synthesizer on my rig only, and received on my K3. 3. The third P3 capture is after K7OLN upgraded his K3 to the new synthesizer, with both radios using the new synthesizer. I have a personal Wiki, and have published the data there at: http://nk7z.net/wiki/elecraft-k3-macros/elecraft-k3-xlr-to-radio/elecraft-k3-new-synthesizer/ Not scientific, but close... As can be seen the new synthesizers make a BIG difference. Bigger than I would have thought! THANK YOU ELECRAFT! K7OLN's purchase of a K3, (I want my Hat Elecraft!), made it such that both he and I can operate on the same band, in the same segment, as close as 10 to 15 KHz away from each other and not even know the other station is there, save the HUGE spike in the P3, (which is supposed to be there), all while at KW power levels for both of us. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info For MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info __ 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

[Elecraft] SMD soldering help
I have done a bit of 0603/4 but mostly 0805 size. What works for me is a small helper I made. Actually the first of two; the second is much more elaborate. I do my boards flat/horizontal in a holding fixture so it doesn't move around. Then I made a 'T' shaped wire 'holder' that rests on the 'T' crossbar. The leg of the 'T' is long enough to bend into a 'C' as big as needed to reach the part. The end of the leg is sharpened to a small rounded point about 2/3 the width of the SMT or 0.02 and rounded with emery paper. A weight is added to the leg an inch or so above the point. In use I place the part with tweezers or other tool and then set the holder tool working end on top so it holds the SMT part in place. Careful use of the solder pencil tip does the trick. Takes a bit of practice but worked well for me. My newer design works better but is, as I say, more complicated to build but as simple to use. Same principle though.

Re: [Elecraft] K3 KBPF3 mod for LF questions capacitor size ?
I can vouch for what Ed has said. Much of the problem is with the fear of small parts. If you have 'eye problems', a magnifying headband can be a great help. Tweezers are a great tool, but be cautious with their use. Too much grip on the part can send it flying to parts unknown where it becomes vacuum cleaner food. A touch just light enough to secure the part is what you want. I prefer straight tweezers while others prefer the angled type - it all depends on how you hold them to determine which is best for you. If you naturally put the main body of the tweezers in your palm, then the angled ones will work best for you. I leave the main body 'sticking up in the air', so straight tweezers work best for me. The prior advice about tinning (putting a small pool of solder) on one end of the existing capacitor is correct. Heat that solder while sliding the added capacitor atop the existing one - when it 'sticks', go solder the other end, and then come back and dress up the soldering on the first end. I don't know about the calming effects of Whisky or tobacco for mellowing, but if you have some technique for calming the shakies, use it. Age is doing its thing on me, and I am beginning to feel the effects of 'tremors'. I find I need to support the heels of my hands on the board or the bench surface to counter that problem. Despite that, I am able to solder SMD components as small as 0603, and I am fortunate that my eyes allow me to do that part without magnification - I then inspect the work with magnification afterwards and make corrections as needed. Use magnification at the start if you are not so fortunate. If you need Microscope enlargement, then a webcam on your computer may be the answer to your problem - that is a 'cheap hams microscope'. In other words, with these hints, give it a try.

You melt that solder with iron and slide in the top cap - hold - carefully remove iron -keep holding a couple seconds till solder solidifies. Now add a bit of solder on the other end. Use an ohmmeter to test continuity from the top cap to the pc trace where the cap is installed. Good continuity - you're done! Continuity across the cap - bad - do over.

Re: [Elecraft] Observation on new Synthesizers for K3
We like to think that a VFO exists only at one frequency -- the frequency on the receiver display. But in reality every VFO has width, and it occupies not only it's nominal frequency but is smeared both lower and higher in frequency, too. This is because of the phase noise of the synthesizer or VFO. Because of the smearing effect of this phase noise, received signals can also appear wider than they are. The noise floor on either side rises in direct proportion to the synthesizer's phase noise. Dave's screenshots of the P3 spectrograms show this smearing clearly. An oscillator with less phase noise looks more like that ideal picture we all have in our heads -- of a signal that's infinitely narrow. In the third of Dave's screenshots you can see how the new synths are closer to an ideal oscillator-- the CW signal's width on the spectrogram is much narrower. If a signal has lower noise sidebands (whether the sidebands are generated in the transmitter or the receiver... each of them has a synthesizer) then you can enjoy less interference from an adjacent signal. You will also *cause* less interference to your neighbors on the band. I have no idea of the design of the new synths, but in general to design a synthesizer with low phase noise you have to start with very low noise devices, pay really careful attention to the parts of the phase-locked loop like the Q, feedback, the numeric dithering, the loop filter and various other aspects of the circuit. It's a real art. It appears from Dave's observations that there is a significant and measurable difference.

[Elecraft] Windows 8.1 tablet power
I bought a win 8.1 (not RT) tablet from Cowboom for $59, hoping to interface it using its micro USB port. However the USB port is the only way to provide power to the thing, and battery life is such I'd like to leave it on charge while operating, while not losing the USB port data functionality. The unit is sold by Best Buy under the Unbranded name. Anyone have luck powering such a tablet without losing the USB data capability? Mark.
