Re: [Elecraft] CW Mistakes
Practice a bit with a partner, or a recording device. It is very important to get the spacing between elements, letters, and words correct. A bad fist will not attract as many QSOs as a good one. Sloppy sending, or a fist with too much swing is a genuine pain to copy. A good fist is a thing of beauty that everyone will appreciate.

Re: [Elecraft] K1
Nope - Don't worry about the toroids. The K1 manual is excellent - has drawings and very clear explanations. I actually think winding toroid is fun! I don't get what all the hllabaloo is about. As far as tinning the leads - the way I do it is use an exacto knife to scrape off the insulation. I find it to be easier and more positive than the hot-solder method. In order for the solder method to work, the iron must be hot - hotter than I choose for actual soldering. If I can do it anyone can. 20-600 vision, thick bifocals, and colorblind to boot. Have fun!

[Elecraft] BL1 vs. BL2 balun
Aside from the switch to change from a 1:1 to 4:1, what are the differences between the BL1 and BL2? I've never seen either, however it appears to me that the BL2 has two binocular cores, and the BL1 has a single core. Is this so? By the way - does anyone know the specs on the binocular core? I'm guessing it is a mix 43.

Re: [Elecraft] ARRL RTTY Roundup
After a week of building a new K1, I was anxious to try it out and get on the air. Imagine my dismay when all I could hear was a racous cacaphony of RTTY splatter from 7.025 to 7.100. Similarly 14.060 was also RTTY hell. I was even pushed off of 10.130 (WARC) by an incessant RTTY CQ TEST. I wonder what drives the ritty boys to swamp the traditional CW bands and wipe out the QRP calling freqs - oh yes, now I remember, the ARRL has deemed CW as non-relevant. Renewal of my ARRL membership is becoming less and less attractive.

Re: [Elecraft] 2SC2166 Driver replacement?
My new K1 seems to have a replacement final as well. I'm going to make a leap of faith and solder in the undocumented 2SC5739 in place of the specified 2SC2166. Carl WA7CS PS: K1 serial Number 2476 is alive and listening - Transmitter installation underway! Don Wilhelm wrote: Put the 2SC5739 in the Q6 position - it will be just fine. Sorry about the lack of an update for the Errata sheet (we can probably blame it on the K3 preparation and resulting overtime at Elecraft). If I can guess a bit, the change was part of the switch to RoHS compliant devices, but that is only a guess. 73, Don W3FPR Matt Palmer wrote: Again I invoke the elecraft gods, i dont have a 2sc2166, mine is a 2sc5739, checking the data sheets these are the same except they have lower voltage, current and power dissapation rating, is this a documented replacement?

[Elecraft] K1 # 2476 alive and well
K1 #2476 just completed it's first QSO. Received a 569 on 20 meters from WA6UIJ's long wire antenna 10 feet off the ground. Not bad for QRP from a ground mounted vertical.

[Elecraft] K1 S-meter / AGC problems
I'm knee - deep into building a K1 Last night - right before my mandatory bedtime I performed the receiver alignment and tests. Everything worked A-OK, with the exception of the S-Meter and AGC. There appears to be no S-meter response, and the AGC does not seem to be working. With the K1 and my K2 connected to the same antenna a S-6 on the air signal (as indicated by the K2 S-meter) provides no response on the K1 S-Meter. I also cranked up the K-2 power to 100 watts to the antenna and monitored the signal with a hank of wire attached to the K1 antenna jack - REALLY loud signal, but still no S-meter response. The K1 S-meter consistently shows one bar regardless of input signal strength. The S-meter bar graph test pattern (i.e. brief display of all the bars) functions when DISPLAY is pressed. I checked the S-meter zero and full-scale settings. If the S-meter zero settings is adjusted with the SIG function, the S-meter bars increase and decrease as described on page 53 of the manual, however there is still no response to input signals. Adjusting the full scale setting similarly does not change response to input signals levels. Due to my assigned bedtime, I was unable to perform the voltage checks at U1, U2,Q1, Q2, D2 in the troubleshooting table. Now, I'm at my desk at work, unable to concentrate on my livelihood. Please offer some suggestions so I can keep my day job!

[Elecraft] K1 crystal grounding
I'm currently building the K1. When I built a K2 a few yers ago, there was an errata sheet or a builder alert, etc. advising that crystal grounding should be done near the bottom of the crystal can as opposed to the top of the can. I can't seem to find similar advice for the K1. I've already installed all of the crystals with the ground wire soldered to the top of the cans. I'm considering going back and tacking the ground wire to the sides/bottom of the crystal cans. Also, in the K2, I seem to recall that all of the crystals were grounded together with a wire along the top - no similar instruction for the K1. Should I do this, or is any potential benefit not worth the effort/risk?
