[Elecraft] K2 #4990
Hello all Yesterday I started building my third K2. This one obviously not for me but for a friend who was very excited to own this little gem. I have just built the control board and front panel board and hope to undertake alignment and test part I this afternoon. Until now and like with the other K2s everything going flawless and with no troubles. I would like to finish this K2 just before my summer holidays to allow Xavier, EA3FTJ, to enjoy it as soon as possible. I am sure he will be delighted with it. K2 #4990 will have as options the KNB2 and KAF2 as far as Xavier is 100% CW. I adviced him to take only those options and try the basic K2 running 10 to 15W (in any case he would be able to upgrade to the K2/100 at any moment). I will let you know about the progress.

David wrote: My K1, once built, will be capable of all six bands. With that being said, If this capacitor is to help with 80 Meters, what does it do to performance if I don't have the band module that contains 80 installed? True, C78 and RFC8 are normally included only with the 80m filter board parts, but they are appropriate for *all* bands. It would be better for Elecraft to simply supply them with the basic K1. So have no qualms...even if you never use 80m. If you have them, install C78 and RFC8 when building the RF board right from the start. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Five hours to K2
When I bought the raffle ticket a month ago it was just helping out a club. I was already planning on buying a rig to replace a dying one (still got it apart). I did, too, a Yaesu FT-920 that we used at FD for CW and which is a very nice radio indeed. However... THAT radio had a 30 day warranty and is is now on its way back to Yaesu for repair. So when I got the E-mail it was good timing. Great timing, in fact. Thanks, SBARA! I don't know what mike pinout the builder wired this K2 for, but a key will work right out of the box.

RE: [Elecraft] k2#4877
Dan and all, There is a more certain method of centering the RIT than 'by ear'. Watch the display while turning the RIT on and off, when the two frequencies agree, it is centered. You don't need to repeatedly turn RIT on and off to do that either - just look at the frequency with RIT off and turn RIT on and adjust for the same frequency on the display. After doing that, one may want to loosen the knob and turn it a bit if the real center point is not lined up with the panel marking. 73, Don W3FPR -Original Message- The kit comes with a RIT Centering tool.

[Elecraft] Interesting Tuner applet
I broke your tuner! snip W9CF wrote a fun little T-match simulator that gives you a front-panel view of a tuner. You plug in the impedance you want to match and press Autotune, and it'll find the match and give you the circuit loss. And you can spin the dials manually and enjoy watching the SWR bounce around G It's at: http://fermi.la.asu.edu/w9cf/tuner/tuner.html /snip I find the applet very interesting. I also find it extremely difficult to get a match (just like in real life). What this tells me is that I don't know how to use a tuner!. I setup several impedance/frequency settings, and failed on all but 1 to get anywhere near the ideal match. The one I did find, the Autotune misses. Maybe Kevin needs to tweak his algorithm. I KNOW I need to tweak my on-air algoritym. Anyone got any rules-of-thumb for getting a match? The problem I stumbled on (the ONLY one where I beat the machine) was: R 100, X 75, F 14.050. I got: 210pf, 1.6mH, 250pf, 1.0:1, 0.9%, 0.0db. The machine gets: 162pf, 0.8mH, 77pf, 1.0:1, 2.2%, 0.1db. Further, maybe I didn't beat the machine. It does it with less inductance, but I get less loss. Isn't less loss better?

Re: [Elecraft] butternut]
RC, I have used them in the past, and found that if you really have a good ground (highly conductive) or lots of radials per band, they are fairly good. Otherwise, much of your RF goes into heating the ground (good for the worms, less good for your signal). If you can get plenty of radials or have a very conductive ground (and much of Louisiana does), you will likely be happy with them; if not, you will be happier with a dipole or a long wire (and a good ground). Of course, any antenna works better in the clear and with a good ground. Consider what the local hams are happy with as part of the equation, and what their communications objectives are; local, medium distance, or DX, and how do their goals match yours? On the average, antennas are the best investment a ham can make; you communicate better and further on average with a poor rig and a good antenna than with a great rig and a lousy antenna. And, they are a double gain; they help both TX and RX, unlike more power. kc5wa wrote: I am wondering if anyone is using Butternut Verticals (HF6V HF9V) for their K2's at their home QTH and how effective have they been?

RE: [Elecraft] Accurate QRP Wattmeters?
Jay, I may have answered this already on QRP-L, but I find the most accurate way to determine power output is to use a good 50 ohm resistive load (check it with an antenna analyzer or use the Elecraft DL1). Measure the RF voltage across the 50 ohm load (RF Probe reads in Vrms while a 'scope will show you Vp-p), then calculate the power. I use this procedure to calibrate or check wattmeters. I don't trust any wattmeter (including a Bird) until I have verified that it is reading correctly - some can be off by as much as 20% and still meet their specs (2 watts on a 10 watt scale, 20 watts on a 100 watt scale), and I can get MUCH closer than that with my known good dummy load. 73, Don W3FPR -Original Message- Hello List, I've posted my question on QRP-L and here as well- since I will be building a KX-1.

Re: [Elecraft] Accurate QRP Wattmeters?
Jay, the Tek 492 will do the job IF you have an accurate way of calibrating it and IF you know exactly the attenuation at all frequencies of interest of the attenuator you will be using. I'm not familiar with the '492... I have a 7L13, and on the 2dB scale the divisions are .4dB.. which are pretty big steps. Don is right about the dummy load method, but first you have to determine the actual Z of the dummy load at all frequencies if you want to be within a couple percent. The resistors in the Elecraft dummy load are 5% metal film, so statistically, the average Z will probably be better than 5%, but unless you can measure it, you won't know. You also have to take into account the diode drop in the Elecraft to wring out the last bit of accuracy. Anything better than 5% absolute power accuracy, BTW, is wishful thinking on the part of manufacturers. Be advised too that even the Birds are rated at 5% of FULL SCALE... meaning ~ 10% of half-scale if that's where your reading happens to be... and that's best case with a purely resistive load. In develping my LP-100 wattmeter kit (more on my website), I learned a lot about power accuracy. It's a very elusive thing. My meter is accurate within a couple % of the calibrating standard at any power level from .1 milliwatt to 2500 watts... but ultimately, the accuracy of the standard determines the overall accuracy of the meter. In my shop, I can measure power to better than .001dB on a relative (not absolute) basis with my HP VNA, but it still all comes down what you're measuring against. One thing I can do, and have done for my own use is create Z vs. freq charts for all my precision loads (and Cantenna and other non-precision loads as well). These charts are accurate to better than 1%. As part of my LP-100 project, I plan to offer a 50W precision dummy load using thick film metal power resistors mounted on a heatsink to allow easy calibration of the meter. It would be a nice addition to any shack. I will provide a custom chart of Z vs. frequency for each one. It will be similar to the Elecraft DL1 in operation, but will use precision parts and come with the custom charts. I am also thinking of making a version of the dummy load with digital readout for power that comes already calibrated. It would be considerably simpler than the LP-100, and would not be a thru-line device, so would not measure SWR, etc. In the meantime, if you have a DL1 and want me to run a custom chart for you, send it with return postage and I will chart it for you.

RE: [Elecraft] Accurate QRP Wattmeters?
Tom, I believe I can answer that - the only thing you need with the DL1 is a DVM and you can either use the formula or the graph from the manual to determine the power. In other words, yes the circuitry is built into the DL1, but a caution, you will find the formula a bit different than the normal because the diode probe circuitry is connected across half the load rather than across the full 50 ohms. 73, Don W3FPR -Original Message- Chuck and all.

[Elecraft] Internal battery question
I recently installed the KBT2 internal battery kit in my K2. I bought this kit from a ham in Australia who had installed it in his K2 and later removed it. Consequently, it had been all assembled prior to my receiving it. I had only to move the various components to my existing cover, mount the connector jack on the main circuit board and plug everything in. I charged the battery overnight and read a voltage of 12.5V the next morning. I then removed the external power supply and turned the K2 on. With the backlight turned off (LCD = Day) and the AF gain at 33% volume, the battery voltage dropped from 12.5 volts to 9.3 volts in four hours. After receiving the kit, I left it on my shelf for almost a year before doing anything with it. When I finished installing it in my K2 a couple days ago, the battery voltage was 8.9 volts before I charged it up. Given the relatively rapid rate at which the battery seems to have been depleted, I am wondering if sitting on the shelf for a year at a charge below 10 volts has ruined the battery. Should I assume it has and just buy a replacement battery? 73, Charlie N1AOK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Internal battery question
I have a bunch of gel cells sitting around here that have been subjected to stress like that and yeah, they go down in efficiency, but I sure would not throw them out if they are working. I might not get as good a time as if I had taken care of them, but they are still useful. Unless it is really bothering you, I would continue to use the thing.

[Elecraft] Elecraft CW Net report for July 3rd 4th, 2005
Another two sessions of the Elecraft CW Net were run this evening. The bands were not as good as I had hoped. Forty was especially tough due to the storms in the heartland. But Ken, out camping, had a very good signal. Not to be outdone however, was a new comer from Bozeman, MT N7GS with a fine signal from his K2. Welcome to ECN. Welcome back to Jerry; it has been a long time and with a new KX1 too. On 14050 kHz at 2300z: N0SS - Tom - MO - K2 - 008 VE3XL - Ric - ON - K1 - 968 KL7CW - Rick - AK - KX1 - 798 K6III - Jerry - CA - KX1 - 1101 W0QQS - Bruce - MN - K2 - 3646 On 7045 kHz at 0200Z: N0SS - Tom - MO - K2 - 008 N7GS - Mal - MT - K2 - 456 W0CZ - Ken - ND - K2 - 1031 VE3XL - Ric - ON - K1 - 968 N7AF - Dave - AZ - K2 - 4795 QNI #10 Thanks to all who were able to join us and sorry to those who listen but could not hear either Tom or myself. There were a few close to subliminal stations out there but even waiting for some helpful QSB was not enough to bring them out. Ric made it the second time on a wing and a prayer. But V??XL is enough for me ;) Can't wait to see the effect of the probe on the comet this evening. Should have been shortly before the second net if my timing is correct. Too light for us to see it on the West Coast but maybe in EU. Please be careful tomorrow. Pat and I will be at the beach eating a little seafood and camping for an evening. I'll take a rig out with a vertical wire and my homebrew ATU. Maybe my might 5 watts will work on 80, 40, 30, or 20 meters or maybe I will just listen. But you never know unless you try. 73 all, Kevin. KD5ONS (Net Control Operator 5th Class) -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

RE: [Elecraft] Internal battery question
Charlie, It is likely that you ddid not have the battery fully charged. What was the voltage out of your power supply - a standard 13.8 volt supply will not adequately charge the battery (see the Elecraft internal battery manual). Before you give up on the battery, try putting a 14.3 volt power supply on the K2 and let the battery charge up for several days, even a week. If the battery is at full charge, you should see a bqttery terminal voltage of 13.8 volts (float voltage) while the battery is connected to the power supply - it will drop a bit after removing the power supply, but not more than a volt. Charge it until that condition comes valid. After that, you can evaluate the discharge cycle and compare with the Panasonic typical performance data for that battery. If the discharge cycle on your battery is significantly shorter than normal, you may want to replace it - examine your needs (portable operation duration, etc.) and decide if the current battery will suffice for your needs. 73, Don W3FPR -Original Message- I recently installed the KBT2 internal battery kit in my K2.
