When I built K2 # 54xx last May 2006, I had high
hope of eventually sending the completed K2 back into "Elecraft's Service Dept" and having it aligned and checked over by the experts. I would have been willing to spend that extra $$$. But - Elecraft Inc. said NO. At which point I came to believe that Elecraft Inc. has no service dept. Sounds like a good opportunity, for us 5800+ K2's alone - to offer this professional factory service.

Possibly the K2 email list archives - would helm us through these troubled waters. Or other experts would surface. Luckily, my K2 build came thru with flying colors, and with the help of Spectrogram - even the filter setup, went seemingly well. But the notion, that "many K2's are out there in poor alignment and in poor performance shape" - is a little scarey. Do you remember the Heathkit Color TV Kits? It was a handfull to build, and it too even had its own test and alignment circuits inside. I don't recall what Heathkit's position was on Service Department?

Hi Group,
Happy New Year! Although I cannot consider myself as an Elecraft expert, I have already built 10 K2 plus numerious modules. The merit of K2 is that it does not require laboratory type of equipment to calibrate and align. I think this has been repeatedly mentioned by other Elecraft experts here. All you need is to closely follow the manual in calibration. With the advancement of technology, good quality frequency counter can be obtained at a very cheap price say US$100. You would need it for frequency calibration. Other than the frequency counter, you will need a Power meter to peak the filters. Any power meters will do a fine job because you need a relative reading only. I have recently bought an advanced LP100 meter from Larry Philip. Upon recalibraton of my K2, I do not see any major difference from the past. For alignment of BFO, the spectrogram is a very handy tool and easy to operate. Again, you do not need expensive equipment. Even you do not use the spectrogram and just follow the suggested settings in the manual, the result is not bad at all. To conclude, I do NOT feel there is a need for factory alignment service. In fact, the design criteria is to avoid calibration using laboratory type equipment. 73 Johnny Siu VR2XMC From: "Fred (FL)" <[hidden email]> To: [hidden email] Subject: [Elecraft] K2 Alignment, etc. What don't I get?

First of all: HNY guys and may 2007 bring all good to you.
I'm not a super experienced builder but I've done a few things here and there. If you are able to build an Elecraft K2, then you simple must be able to do the alignments. Alignment is not the difficult part. Just do it. Getting the right parts in the proper places and solder everything right without any damage; that's the challenge. I'm reading this reflector for about6 months now and have learned a lot about the K2 this way. IMHO nearly all the messages are about faulty components, right components in wrong places, solder blobs etc. Problems with alignments are mostly traced back to a small mistake during the building of the kit. Therefore I think the problem is not the alignment of the K2, it is faultfinding. Question is if one would like to send a not aligned (or better not alignable) K2 to one of the experts of this group for alignment? I'm afraid it will come down to faultfinding. (Again my humble opinion). 73, Arie PA3A -----Oorspronkelijk bericht----- Van: [hidden email] [mailto:[hidden email]] Namens Fred (FL) Verzonden: zondag 31 december 2006 17:55 Aan: [hidden email] Onderwerp: [Elecraft] K2 Alignment, etc. What don't I get?

I agree Arie. I think the issues are more concerned with a lack of
confidence in people's construction abilities. If you believe you have assembled it to a high standard then you will have confidence that you can align it correctly. Fault-finding can also be daunting but there is considerable assistance available on this Reflector. Perhaps the other point to make is that it is sometimes difficult to believe that having assembled such a complex looking set of boards with so many components, alignment can be so simple.It is easy to make your self believe that there must be other more technical things to do to male it work properly! I do have some receiver spec issues but will post those separately.

I try to compare my K2 to others when I get the chance. This helps show
up flaws that wouldn't otherwise be apparent. For example, imine wasn't as "quiet" as had been reported by others, and I traced the problem to my having damaged the mixer on installation. The MDS was fine, but something (the modulation products from other signals perhaps) were causing a harsh noise. The DSP also started workiong better, as it had always had more noise to contend with. The funny thing is that I had ordered a replacement mixer (not a cheap part!) but since it looked difficult to remove, had put it off, because the MDS test was ok. It was the compare-and-listen test that told me something was wrong.
