Rick Dettinger wrote: I could probably get the SWR on 40 meters down by changing the feed line length. Of course, this would change the other bands. Easier than trimming (and maybe lengthening!) window line is the following: wrap a piece of aluminum foil about 1 foot (30 cm) wide around the ladder line. Slide it around on the line until you find a place where all the bands are within matching range. You can use more than one piece of foil if it helps. You have made a capacitor whose effect on the impedance will be greater as you approach a voltage loop for a particular band. I have done this successfully with a few hundred watts -- it probably would not be good for very QRO situations where the voltage loops can reach thousands of volts, but it should be safe for your KX1 :-) -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Tuning 88' with KX1 autotuner?
Jim - That is my antenna, currently installed as an inverted vee with center at 40 feet. I have about 80 feet of window line. I just tried it with my KX1 using an Elecraft 4:1 balun. [Usually, I use an outboard Z match tuner (NORCAL)]. On 40 meters, I got an SWR reading of 2.3 while 30 and 20 meters were 1.1 and 1.0 respectively. I could probably get the SWR on 40 meters down by changing the feed line length. Of course, this would change the other bands. The balanced antennas are harder to match than the end fed wires recommended in the KX1 ATU manual. I get close to 1.0 on all 3 bands with an end fed 80 foot wire sloping up to 30 feet and a 33 foot wire laid on the ground. I highly recommend the KX1 for portable use. 73 - Rick - K7MW - Original Message - From: "Jim Miller" <[EMAIL PROTECTED]> To: Sent: Sunday, February 20, 2005 3:21 PM Subject: [Elecraft] Tuning 88' with KX1 autotuner?

[Elecraft] Elecraft CW Net Report for February 21st, 2005
Good Evening All, At z the 20 meter band fell silent. Then, out of this silence sprang the Elecraft CW Net. Folks were not too tired to slow down from 40 wpm contesting speed to check in. 17 folks on the first net and 12 on the second one. The bands were not worn out but seemed quite good across the continent. Alaska to Florida and New York to California. Pretty good geographic spread. K1s, K2s, and KX1s were represented as well as the odd glow bug instrument. Ken, W0CZ, won the coldest town award and was going for two during the second net. 12 degrees F is a bit chilly. Palmer, Alaska and Greely, Ontario, Canada could not beat that mark. There was a bit of snow out East but not too much for the folks in ND, PA, and IN to handle. No reports of snow or cold from Colorado though. A few new faces and a lot of familiar ones. Nice mix all around. But, on to the lists.

[Elecraft] First Contest With K2 # 4616
K2 4616 built by Alan W1HYV had its first major workout in the QRP all band category during ARRL CW over the weekend. Didn't have as much time to operate as last year (3rd place) but the results of a casual operation were: Band QSOs Country 1.8 1 1 3.5 44 35 7 131 53 14 16051 21 14951 28 26 1 8 Total 511 209 Score: 319,143 The K2 is amazing! The receiver / DSP is the best I have ever used. The reduction in operating fatigue during S&P operation is significant .. I was able to work stations in the noise that I couldn't hear with my other QRP radios. KH6 & TF on 80M were good examples. Thanks to Eric and Wayne for a great design it is world class!! Also many thanks to Alan for a great job with the construction.(My manual dexterity isn't what it used to be and I wasn't comfortable with the K2 as a first effort.). 72/73 Tom N1TM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Tuning 88'
For reference, I have tuned this exact 88' CF doublet with 75' of balanced feedline with the K2 ATU and it easily tunes on all bands and modeles very well on 40-10. I used a homebrew 1:1 current balun right before it went into the BNC connector of the K2. Operating in the field on a battery for FYBO in the hail, I drew big static arcs to my EARS through my HEADPHONES until I ran a simple static ground from the K2's GND post to a nail pushed into the soil. What a Shocker! (sorry). I made my doublet AND feedline from 26AWG 19-strand copper weld wire intended for balloon lift that is VERY strong and flexible but doesn't twist or kink and seems to weigh nothing. I highly recommend it for a field antenna: http://www.davisrf.com/ham1/flexweve.htm Bottom of the page, PN "POLYS-26" Good stuff. 73, Steve N4SL __ Do you Yahoo!?

[Elecraft] New awards & announcement.
To all Elecrafters, Due to the inspiration of Arnold Olean KØZK, I am happy to announce two new Elecraft Awards. Arnold has already earned the first and is the proud owner of certificate #001. The new award that Arnold has earned is the Elecraft "50 in 50" Award. This is earned by using your Elecraft rig(s) to work another Elecraft rig in each of the 50 United States. This does not replace the existing Elecraft Worked All States Award - it just brings it to a new and separate level. In the same vein, I am also announcing the new Elecraft "100 in 100" Award. This award can be earned by using your Elecraft rig(s) to work another Elecraft rig in 100 different DXCC entities (as defined by the ARRL DXCC department). Again, this does not replace the existing Elecraft Century Club Award. This one is totally different and introduces an exciting new challenge. Is it possible to even achieve this award? As Elecraft becomes more and more popular around the globe; and as we have seen Elecraft rigs being taken on major DXpeditions - the answer has to be "yes"; but it will be a challenge! Full details on how to apply will be forthcoming in the next few days. For now, the application for the "50 in 50" Award will be the same as for the basic "Elecraft Worked All States" Award with the added provision that you must supply the model and serial number of each Elecraft rig that you have worked. I welcome any and all comments, questions and suggestions - please contact me off list via [EMAIL PROTECTED] 73 es happy operating! Larry W2LJ Your Humble Awards Admin.

[Elecraft] K2/100 magnetic screening?
Has anyone successfully improved the K2's immunity to magnetic fields, e.g. from nearby mains transformers? I'm thinking of making a mu-metal cover to enclose the K2 (apart from front and rear), leaving room for air circulation top and bottom. I think this should do the trick, but wondered if less drastic action would surfice, e.g. lining the bottom panel with steel or mu-metal. In my case the nearest mains transformers are two feet away or more, off to the sides and rear, and it's not really practical to increase the separation further. I've had reports of less than T9 and tests indicate it's due to these transformers, one in the linear amp. and one in the linear PSU that powers the K2/100. No problem on receive, but the magnetic field is obviously stronger during TX. Thanks / 73 Fraser G4BJM #4368. _ It's fast, it's easy and it's free.

If you like a copy send me an email ([EMAIL PROTECTED]) Also comments and suggestions for improvments are very welcome !

[Elecraft] K1 Builders
Hello K1 builders, I am currently (since Autumn last year) building K1 (no. 1550). It is the first kit I am building and I am droping from problem into next problem. Looks like soldering isn't my thing. Perhaps someone can help with my actual problem. I have reached chapter 7. When I am doing the LED-test the ATTN LED first turn on briefly yellow, then the RIT/XIT turns on green and then red (instead of orange), finally the ATTN LED turns on again briefly orange. Any idea why? The other thing is that the rig sucks (all LED off) 83 mA and 93 mA (instead of around 55mA, mentioned in the manual). It does most of the alignment and test in chapter 7 the correct way, but I can't do receiver alignment as described in the KFL1-4 Manual. Even using a hamradio transceiver on a dummy and a short piece of wire in the antenna jacked I don't hear anything. First the rig is very quite, but then - suddenly when doing some manipulations on it (but I can't find out a specific manipulation that causes it) there is a lot of noise in the loudspeaker (and the S-Meter shows on full scale). If someone has any idea pleas give me a hint. Thanks very much! vy 73 Gernot DL2FN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 PLL Ref. Osc. Range Too Narrow
Mike and all, There is a note in the "What's New" section of the Elecraft Builder's Resource webpage that says a PLL Range of 8.8 to 18 kHz range is OK. It seems that information has not made it into the Errata pages yet, butr I expcet it soon. As I understand things, a narrow PLL range is better than a wide one - the PLL reference will be more stable. 73, Don W3FPR > -Original Message- > > I'm building my first K2, purchased about two months ago, and I've hit > a little bump during alignment and test (part 2). > > During the PLL Reference Oscillator Range Test I came up with too > narrow a range (9.37 kHz somewhat below the 9.8 minimum)).

Re: [Elecraft] Ultimatic Keying.
One step away from a bug in that a string of dahs not just one dah comes out when you hit and hold the dah paddle. There is a circuit in "Solid State Design for the Radio Amateur" page 178 that I think does this using three NE555 'timer' ICs, VERY simple, with a pot controlling speed. The Dah, Dit and Spacing times can also be adjusted to suit the user's taste. The authors were discussing applications of the NE555, not keyers as such. CMOS ICs would keep the power draw low. 73, Geoff.

[Elecraft] K2 PLL Ref. Osc. Range Too Narrow
Hello Group, I'm building my first K2, purchased about two months ago, and I've hit a little bump during alignment and test (part 2). During the PLL Reference Oscillator Range Test I came up with too narrow a range (9.37 kHz somewhat below the 9.8 minimum)). My high freq. ref. during the test was 12099.95, and the low was 12090.58). I gather that my low point is not low enough. I did check the components listed in the trouble-shooting section (D16, D17, C84, C85. L31) and they are ok. I have also checked all soldering, and it looks fine. I have looked over many of the messages on the list, but still wanted to put out a request for help to those experienced with the K2. I have seen some reference to a range as low as 9.1 kHz being ok (others say it needs to be at least 9.8). I have also read that going to an L31 value of 12 uH is a solution. Anyway, as always, helpful comments are welcome. Mike/NR7F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
