[Elecraft] Sierra's 10th
Wonder just how many of us have had the pleasure of using N6KR's design, the NORCAL Sierra? I picked up one on eBay and find it to be one sweet li'l rig. I've had it on 40 and 20 with consistently good reports. The rx is a pleasure to listen to. Definitely a keeper! I read somewhere that Field Day, 1994 marked the prototype's debut. So happy 10th, Wayne! Bill K3UJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post. Subscriber Info (Addr.

I picked up a Sierra about 3yrs ago. Nice rig but just a prelude to bigger and smaller better things. -- 73 ditdit, Doc YI9RVT/KE4RVT Al Kut, Iraq ***All emails and attachments scanned by Norton Antivirus with current definitions*** N33.29 E45.45 FPQRP #85 KX1 S/N 0337 QRP-L #2201 (sk)K1 S/N 0113 ARS #1696 K2 S/N 2768 FIST'S #10652 FT897 QRPARCI #11746 www.qrparci.org www.arsqrp.com www.fists.org Sometimes a little brain damage can help.

[Elecraft] Re: CW Readers and CW Keyboards
CW Get works pretty well when you monitor something like W1AW doing code practice (with strong non-QSBed signal) but on real signals you get drop-outs and a series of e e e e t t tt et te nonsense on very slow unsteady signals. The problem is that it is the best that I have tried! The human head is the best interface for receiving Morse. For keyboard keyers try something from K1EL (http://www.k1el.com) for $25 he has a kit (K-20) that is a keyboard keyer with variable speed, weighing, memories, etc. all you add is the keyboard (inexpensive computer type keyboard) or use it with paddles as a keyer. This unit would make a good keyer for portable operation as no computer interface is required, comsumes little power, and can be powered off the 12 volts for the K2 or whatever. He has several other kits. He is easy to deal with and takes PayPal. I am not associated with K1EL and his business.

[Elecraft] CW Readers and CW Keyboards
Larry Keith, KQ4BY wrote:: Has anyone used a CW Reader and/or CW keyboard with the K1? I would be interested in hearing about your experiences.. I've used one of K1EL's K20 keyers with my K2. Its an interesting kit with two PIC's and an EEPROM chip. One PIC is the keyer, one PIC is the keyboard interface, and the EEPROM chip saves all your current parameters and messages. The keyboard is used to control the keyer and can also be used to send CW from the keyboard if you are tired of using your paddles. The K2 was set up to accept straight key input, so it should also work with your K1. For me, it was an interesting kit project for under $30. The web site www.k1el.com indicates that he is currently out of K20 kits, but he has responded to demand with additional kits in the past. The usual disclaimers apply. I'm just a satisfied cuatomer. 73, Doug, VE3MCF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.

Re: [Elecraft] CW Readers and CW Keyboards
The K1EL website indicates that the K20 will be soon replaced with the K40 at $27 with shipping to USA/Canada. Awaiting a reply from K1EL when this will be available.

[Elecraft] KX1 Desk stand...
Hi All, A couple of days ago I was trying to devise a small desktop stand for my KX1 to make it a bit easier to operate while seated at my desk. Having it elevated and tilted forward were primary concerns. I noticed a couple of recent posts on the reflector about the same subject and thought you might benefit from what I found. I tried a couple of unsuccessful homebrew clipboard-type ideas, but eventually discovered a small metal Mesh Sorter at a local Office Depot (Item No. 346-395, about $7), which serves the task nicely without having to do anything other than just putting it to use. The sorter is a tiered, 4-divider desktop stand measuring about 3D X 7W. Its black finish matches the KX1 covers reasonably well. Its dividers of four different heights afford the KX1 several convenient positions to rest on while the paddle or any of its switches are operated. It seems quite stable and works well for me. The KX1's rubber feet rest securely against whatever divider I choose. The lowest one keeps the paddle at an excellent height for me. I have no interest in Office Depot, other than the fact that my local store seems to have a good selection of stuff that frequently is helpful for devout scroungers like me. 73...

[Elecraft] K2 - no TX power problem
Hi, I have a problem: No TX Out on my freshly assembled K2. f = 7100 Vpwr = 5V Valc = 7,5V Power reading on LCD = 0.2W (desired 5W) Power consumption 440mA on 12,4V At TP2 on transmit I get a nice signal on my oscilloscope, abt 0.005 Vrms But behind TP2 the signal vanishes. All measurements are way too low, if present at all. At U10 Pin 4 there's only a short Jump to 5V and immediately back to 0 on keying. No HF detectable. I unsoldered the Diode D36 and checked for resistance. Infinite in both directions. Does this mean what I think? This D is broken? Do you need any more information? What else could I check? Thanks for any advice in advance!

[Elecraft] Re: Sierra's 10th
Thanks for noticing, Bill ;) Not as well known is that I had a bit of help from Eric in test/refinement of the prototype Sierra. So 2004 also marks the 10th anniversary of our first collaboration. Also, the Sierra wouldn't have happened without Doug Hendricks, KI6DS, and Jim Cates, WA6GER (SK). These guys worked tirelessly to promote the Sierra (and other designs) as club projects, and deserve much of the credit. 73, Wayne N6KR On Jun 24, 2004, at 4:45 AM, [EMAIL PROTECTED] wrote: Wonder just how many of us have had the pleasure of using N6KR's design, the NORCAL Sierra?

Re: [Elecraft] K2 - no TX power problem
Gerhardt, Yes, I too would believe D36 is broken - it is quite fragile and will crack if the leads are bent too close to the glass body - HANDLE WITH CARE. You can temporarily substitute a 1N4007 diode until you can obtain a replacement (the 1N4007 was used in the D36 location until the keying waveshape change was implemented). You can likely find a 1N4007 easier than the proper PIN diode. With the 1N4007 in D36, your keying waveshape may not be exactly correct (it will be close enough), and it should get you through the testing of your K2. 73, Don W3FPR Life is what happens when you are making other plans - Original Message - At TP2 on transmit I get a nice signal on my oscilloscope, abt 0.005 Vrms But behind TP2 the signal vanishes.

[Elecraft] Field Day dipole/ no radial vertical
I've been having considerable success with the resonant feedline dipole (RFD) antenna as was described in QST a few years back and also in the '04 ARRL Handbook. Its basically a 1/4 wavelength of antenna wire followed by your coax feeder into the shack. Where they connect, the coax shield is left floating. Some of the feedline is wound into a choke at the 1/2 W/L point or thereabouts, decoupling and forming the dipole. (Position the choke for lowest swr.) With the far end pulled up high, they are good for long haul DX. I have one cut for 40m and it works well with low swr on 30m, 17m, 15m. and 10m. Another one for 20m rounds out the little farm. Mine aren't exactly vertical (kind of exponentially curved) and seem to be a bit directional. YMMV of course.

[Elecraft] Field Day Antennas
This will be my 2nd Field Day for my K2 #3421. This year I'm going to try my Commercial Buddipole (this time it is almost twice as long with three pairs of antenna arms and the 4 segment shock-corded whips). I'm also going to try throwing up a W3EDP (85' inverted L with 15' counterpoise) for the low bands and a compact transmitting loop (20' of 1/4 copper pre-tuned with matching coax stubs for 20m and 40m). Complementing my K2's power needs are the internal KBT2, a 7 AH external gel-cell, and a small 5W solar panel. My question for all of you Field Day guru's... I'm closing on my first house today. None of these antennas exist at the house. If I set them all up in a temporary sort of way in the backyard and take them down after Field Day is done, can I still be considered 1B (especially if I decide to log with a laptop plugged into commercial mains, and maybe drag the K2 inside when it gets too hot outside)? The laptop won't be used for sending or receiving, just logging. No towers or masts exist at the new QTH. Thanks for your rule interpretations in advance... and enjoy Field Day! - Daniel / AA0NI Oklahoma City ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.

[Elecraft] FS:KAT2 ATU
I have a brand new KAT2 that I built, aligned and tested but never got around to using it. Thought I would work QRP portable but never did. I bought it about three months ago and now I am selling it. I have built many K2's and other kits for many years so it is well built. I'd like to get $140 for it and that includes shipping in the lower 48.

[Elecraft] KIO2 Noise
Hello, I just installed the KIO2 option in my K2. All works well except that I now obtain a lot of noise on my PSK31 waterfall display. The noise is effecting the decoding of the PSK31 siganls. If I disconnect the serial cable from my laptop, the noise disappears. In the instruction manual it stated to not connect the sheild on the PC end of the KIO2 cable. I assume that this was to isolate the K2 RF/DC ground from the PC ground? Any suggestions on reducing the noise? Would putting a ferite choke on the cable be worth while? 73s, John - KI7V K2 #3706 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.
