[Elecraft] ANNOUNCMENT: QRP-ARCI(sm) SILENT KEY MEMORIAL CONTEST
Good Day everybody! Please note that the BUBBA contest was inadvertently scheduled in a manner that conflicted with the 2005 running of the SK Memorial Contest. The organizers of the BUBBA event have apologized and modified their contest exchange to match the exchange of the SK Memorial Contest. A Contest TWOFER so to speak. The sending of the temperatures that is the basis of the BUBBA contest has been made optional, but please be courteous and comply with any requests for temperatures from BUBBA operators. Thanks Everybody. 73/72 Jeff - VA3JFF QRP-ARCI Contest Manager 2005 SILENT KEY MEMORIAL CONTEST ANNOUNCEMENT This contest celebrates and honors the QRP luminaries who no longer answer CQ's. Those generous people who graciously donated to the QRP community their time, effort and knowledge to advance the premise that more fun could be had using less than 5 watts. Some were irascible and some were even considered curmudgeons but when you took a keen look at their accomplishments and listened to those who knew them well you discovered truly wonderful people who would give you their last diode. The people we are celebrating are well known among the QRP Community. Some passed recently and some have enjoyed their reward many years. They are not forgotten for their accomplishments live on either on the bands, the internet, through published works or organizations that benefited from their largess. This contest celebrates ALL SK's who now call CQ from above, where all sigs are 599 and all contacts QSL 100%. Celebrate the many SKs that we have known and loved in years past. Date/Time: 20 August 2005, 1500Z to 1800Z. Mode: CW Only Exchange: Members send: RST, State/Province/Country, ARCI member number Non-Members send: RST, State/Province/Country, Power Out QSO Points: Member = 5 points Non-Member, Different Continent = 4 points Non-Member, Same Continent = 2 points Multiplier: SPC (State/Province/Country) total for all bands. The same station may be worked on multiple bands for QSO points and SPC credit. Power Multiplier: >5 Watts = x1 >1 - 5 Watts = x7 >250 mW - 1 Watt = x10 >55 mW - 250 mW = x15 <55 mW = x20 Suggested Frequencies: 160m 1810 kHz 80m 3560 kHz 40m 7040 kHz 20m 14060 kHz 15m 21060 kHz 10m 28060 kHz Score: Final Score = Points (total for all bands) x SPCs (total for all bands) x Power Multiplier + Bonus Points. Bonus Points: If you are operating PORTABLE using battery power AND a temporary antenna, add 5000 points to your final score. (You can NOT be at your shack operating from battery power using your home station antenna to qualify for this bonus.) This is to help level the playing field for contesters who work from the field against contest stations with 5 element yagis at 70 ft. Categories: Entry may be All-Band, Single Band, High Bands (10m-15m-20m) or Low Bands (40m-80m-160m) How to Participate: Get on any of the HF bands except the WARC bands and hang out near the QRP frequencies.

When I first built my K2 in 1999 my eyes and brain were fine, but now when building the Kio2, KPA100, Kat100, KDSP2 etc, etc, ...well I made a whole lot of mistakes and blew a lot of parts. I got to know the Elecraft technical staff very well ;o). I got to the point where whenever I blew a part or something didn't work, I would not worry in the least since I knew that when I called the next day they would set me straight and supply me with the proper replacement parts. Rest assured that anyone can build a K2 and not to worry about getting it to work. With this list, and Elecraft staff it’s a done deal. Steve, W2MY -- No virus found in this outgoing message.

RE: [Elecraft] Power Supply
Stan, If the voltages are ALWAYS exactly the same, you could be OK, but if the voltage sags on either supply, the one with the higher voltage will try to feed into the lower voltage supply just as if it were another load. What happens next depends on the exact power supply design. I would surmise that for one thing, connecting two supplies in parallel will possible defeat the foldback current limiting. It would be much better and safer IMHO to use 2 distribution boxes - unless you have one piece of gear that requires more current than the Astron can handle by itself. If I were going to attempt to parallel 2 supplies, I would check that the design (mainly the protection circuits) allows them to work together properly and definitely would NOT attempt to parallel 2 different supplies. 73, Don W3FPR > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Stan Rife > Sent: Thursday, August 18, 2005 6:57 PM > To: elecraft@mailman.qth.net > Subject: RE: [Elecraft] Power Supply (WAS: New amp) > > > That's what I have done here.

[Elecraft] Elecraft Support the Best!!
I know I'm preaching to the choir here but once again Elecraft has proven they have the best customer support in the world! After a recent portable operation with my K2 and KPA100/KAT100 in an EC2 I returned to find that the K2 would no longer control the amp and tuner. A quick swap of the QRO and QRP lids isolated the problem to the KIO2 in the K2. A check of the email archives suggested one of the subminiature RFCs was likely the problem. A quick check with the DMM showed that L1 on the AUX2 board was open. This is the 12V control line for remote connected devices. A quick email to Elecraft and Richard verified this was the cause of the problem. I sent back asking if this RFC was susceptible to failure due to high current when used with the remote KPA100. He wrote back and said yes and forwarded a copy of Lyle's (KK7P) article on remoting the KPA100 which specifically recommends replacing the subminiature RFC with a torroid wound on an FT23-43 core similar to L5 in the KIO2. I was all set to order one from Elecraft when Paul, Gary and Scott each sent emails telling me that they were sending me a couple of cores and some wire. Are these guys great or what? I had also suggested they consider changing the kit to replace the subminiature RFC on the AUX2 board with a torroid version and it sounds like they will be doing that soon. What other company provides such service. Outstanding! They truly are the best in the world for customer service. Unless Elecraft doesn't offer it, all gear in my shack will be Elecraft! 73, Mike WA3KYY K2 #2221 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Power Supply (WAS: New amp)
That's what I have done here. I have a 20 amp VJ Products and a RS-35 Astron. I have them in parallel and fed in to a home brewed distribution box. I had often wondered if the difference in current rating would create any problem. Also, I have never checked to see if they both have exactly the same output voltage.

And that's why I said one must be careful with a high-current supply. It's a lot harder to trip that crowbar circuit on a big supply! As I pointed out, a 13.8 volt, 50 amp supply will deliver full current into a 0.3 ohm load WITHOUT OVERLOADING! That's 690 watts that can cause a lot of heat in short order, and it won't even trip the crowbar. Where I've found some ops get a nasty surprise is that they've become used to seeing the crowbar kill the output when they accidentally short out a 5 or 10 amp supply, but when they do that with a bit of solder or wire on a 50 amp circuit, they're met with a face full of molten copper, solder or whatever it was that got across the circuit and the power supply barely hums...

Re: [Elecraft] Power Supply (WAS: New amp)
Not to take issue with Ron's comments... they are all appropriate, however one thing I think which may have been missed, or at least glossed over, is the fact the Astron supplies include a very good FOLDBACK CURRENT LIMITING circuit which, if directly shorted (e.g. HOT lead directly to GND) will instantly reduce the output current (and the voltage) to nearly zero with little or no damage to the supply, the attached equipment, OR to the cabling (or user). This having been said, as with just about any P/S which included this type of current limiting, if only a partial short (e.g. low resistance, but not quite a dead short) appears across the output, the P/S will attempt to provide as much current as it can.. until it reaches that 'trip point' internally set at which it then thinks it sees a dead short and reverts the foldback current limiting. So, if you place a really heavy load across such a p/s, it WILL try to honor your request, so to speak. All too often, I've (accidently) shorted together the "+" and "-" leads of my Astron VS35M (35A) supply. The only thing I hear is a momentary 'tick' when the wires touch, and the I see the voltage and current drop to zero... removing the short brings everything back to normal. This is definitely NOT something you'd want to do with a P/S you weren't ABSOLUTELY CERTAIN has foldback current limiting. For, as Ron stated so eloquently, BAD THINGS CAN (AND WILL) HAPPEN!!! 73, Tom Hammond N0SS At 12:51 PM 8/18/2005, Ron D'Eau Claire wrote: David wrote: Thanks everyone I have the answers I need and I am now planning to purchase an rs50m for my shack --- A few things to consider: 1) A 20 amp power supply will run the K2/100 with current to spare.

Re: [Elecraft] K2 tinny speaker
Craig, this comes up from time to time. Check the speaker mounting for the screws being overly tight and distorting the speaker frame. Or check that the frame is not bent or warped. You have to dismount the speaker to check that. Don't overly tighten the speaker mounting screws when you replace it. Sometimes, pressing two fingers near the voice coil will remove distortion showing that the voice coil is either under tension or is warped in its centering in the magnet field. Most of these cases turned out to be too much torque in mounting the speaker hardware to the top plate.

[Elecraft] K1 BFO alignment
I'm building a K1 to go with my K2 and KX1! The receiver is working and aligned, but I have a question about BFO alignment. I usually use a side tone pitch of 700 Hz, but I don't seem to be able to adjust the BFO trimmer c20 to get that high a note centred in the filter pass band. Am I aiming for the impossible, or should I have another go? I could always reduce the side tone pitch on my other rigs and get used to a lower one, I understand that's the way many experienced ops go. 72/73 Paul M0CDP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] New amp
If I remember correctly the power supply is included. It is a switching supply. With the smaller amp it is built-in. With the larger amp it is external.

[Elecraft] KX-1 #1204 Operational
#1204 is up and running without too much difficulty, other than the builder making a "rosin joint" at one of the relays which was quickly resolved. I made a few contacts up to 1500 miles away on 10 and 14 MHz, using 1.5 watts (internal batteries) and a Barker & Williamson AC 1.8-30 broadband antenna. This antenna while a great 1.6-30 MHz antenna for 100-watts and higher, MARS, military and allband use- is probably 6 dB down from a center-fed doublet or end-fed wire of similar shape... Still beats a short mobile whip though. The audio with the adjustable crystal filter sounds better than a comparison IC735 and an IC728, both with "CW Narrow" filters. The 600-Hz offset and sidetone is a lot easier for the ear and the brain to make out- compared to the 800-Hz sidetones and offsets in the Icoms and some other models. Now, the final part- choosing some good earbuds and a Pelican or other box for briefcase/suitcase/glove-box.
