[Elecraft] kxpa100 mobile/ portable mounting.
Not having the facilities to bend and drill angle brackets to mount my kxpa; what are others using? I am planning to put together an H shaped wooden structure, large enough on the top for the amp and a power supply. The bottom of the H will probably be empty space as I keep my KX3 and all accessories in a nice lunch bag. __ 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] keys by VE3GHN
I purchased a key make by VE3GHN at a flea market and it is a really nice straight key. Made of brass and on a wooden base. Frankly it has become my favorite straight key. I have seen only one other example of his keys on the internet. If anyone has pictures, descriptions, etc. I would appreciate it. Len is an SK. I have no idea how many keys might have been produced but I suspect that many were one off units.

Re: [Elecraft] Miniature self-supporting HF antennas
I am not an antenna purist and will use whatever is handy but my favourite antenna (at the moment) are a 44 foot Center feed zepp with tv twinlead and a 4:1 balun or if trees are not available I really like my semi homebrew center loaded vertical using a 12 inch base rod, a Wolf River Silver Bullet coil and a collapsible military whip for 80/40 or just a 36 inch whip for 20 - 10 if I want to be stealthy. I had a buddy stick but it is to finicky to tune, whereas the Wolf river coil just slides down for maximum noise and let the KX3/KXPA take the last bit of swr out. For radials you can't beat the tape measure radials. On Sun, Jul 19, 2015 at 12:45 PM, Wayne Burdick n...@elecraft.com wrote: Hi all, Have you found the perfect above-the-treeline backpacking antenna for use with your KX3 or other small rig? I've used everything from a 10-meter coat hanger whip, to a yagi that breaks down into two dozen pieces, to a dipole held up at the center by a willing (and tall) campmate. The variety (and price range) of such antennas is staggering. I've had pretty amazing results using short, base-loaded antennas on the higher bands--especially when conditions were good. My personal best is JA from W6 on 15-meter SSB, running 3 watts to a Maldol 48 whip. These antennas collapse and break down into just two pieces, taking very little space in my lightweight go-bag. This leaves room for a couple of 25' wires, adapters, and weights for times when there are trees available. But the search for the ideal miniature HF antenna continues: something both very compact *and* highly efficient. Ideally it would break down to a length of 8 or less, do an excellent job on 20 meters and up, and earn a passing grade on 30 and/or 40 meters. One other key factor, at least with the KX3/KX1/K1 genre, is to take maximal advantage of the rig's internal ATU. A wide-range ATU (such as the KXAT3) can turn a narrow-banded antenna into one that covers a full band or even multiple bands, within limits. One general approach is to coarse-tune the antenna's own inductance, then let the ATU do cleanup. Is the best antenna for backpacking a very small magnetic loop? A cleverly designed, center-loaded telescoping whip? A length of #30 wire lofted by a small helium balloon? (Or, more intriguingly, some combination of these?) I'd be interested in hearing about your antenna theories and field experiences, backed up by entertaining fish stories, if they aren't embellished to an embarrassing degree. If your supporting documentation is too voluminous for the forum (attached photos, etc.), feel free to email me directly. If anything substantive or surprising emerges, I'll do a followup posting. 73, Wayne N6KR __ 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 bill.va...@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
[Elecraft] Info needed on 'Crimping'
After year of using a simple crimper - you know the 5$ kind that do an ok job. I bought a 7 pc quick change ratcheting wire terminal crimper kit. Now, I need to know how to use it and the various 'jaws'. I have looked on the internet, checked the local library and can't find much. Utube has a bunch of videos but mainly they are not useful. Does anyone have a 'crimper's bible' the kind of thing that tells me about the various jaws and do I put the terminal in the front or back? I have lots of questions but can't find much in the way of answers. One of the reasons for this is that I have been playing with a 160 meter antenna which needed to be lengthed. Other than using a torch in a forest (not a great idea) I thought that butt connector would work for my experiments. And they have; beats using up my long wire pieces on an experiment. Any help would be appreciated.

[Elecraft] cooler KX3
With all of the commercial hype about heat sinks and little real world data I would like to add my 20 cents worth of comments. I bought a heatsink from KB8UHN (see his QRZ page) . This heatsink is smaller, both in thickness and fin size. I was happy running winmor/RMS with the stock KX3 from home running 3 watts but I thought a bit bigger heatsink would allow me some higher power and with the diminutive size of John's heatsink I would not be snagging all sorts of items on the picnic table while portable. Once I installed it I did some totally unscientific testing with the following results: Test 1: start temperature of PA: 32 after 5 minutes: 56 Test 2: start temperature of PA 30 after 5 minutes 54 Test 3: start temperature of PA: 28 after 5minutes 53 These results are summarized and I will happily sent you the total Xcel spreadsheet. The above data was taken at 10 watts into a dummy load with the key locked down (on 20 meters) and are expressed in degrees Celsius. Room temperature was about 25 degrees C, no breeze or air movement. These temperatures compare very favorably with any other data that I have seen posted for the much more expensive KX3 Heatsinks. The heatsink also allows you to use the Sidekx handles and cover. I can't think of any mode that I would use my KX3 on which would require a larger heatsink but your operating habit may dictate otherwise.

[Elecraft] kxpa100 remoting
I want to remote my KXPA to the base of my antenna in my RV. My RV has a storage locker door 2 feed from the rear ladder and would be an ideal place for the amp/tuner but the interface cable is causing some problems. The manual specifies Cat 6 cables that are STP (shielded); max. 25 feet. My search for a cable locally has failed. Without a trusted source on line I hesitate to pay something in the neighbourhood of $70 cdn for an unknown quality cable. Has anyone tried unshielded cable?; Cat 5E cable?;or whatever! Any wisdom on the subject would be appreciated.

[Elecraft] k3 and rms express-.Help needed.
I seem to be hit and miss with RMS Express and my K3. Sometimes it works and sometimes it doesn't... ok, part of the problem is that I also use my KX3 with RMS express. Both have worked in the past - until I fiddle with one of the settings! Which one? I have no idea! Does anyone have the RMS/K3/KX3 settings that they can share with me? My setup is as follows: K3: line in/ line out via griffin Imic sound card (using a netbook without a mic in) data mode KX3 using a signall link USB. data mode. Thanks for reading this.
