Re: [Elecraft] K2 crystal filter question
You can get a pretty good frequency display from CocoaModem. Peter N8MHD On Sat, Feb 27, 2010 at 8:07 AM, lstavenhagen lstavenha...@hotmail.com wrote: Ok thanks Don. I'll be darned hi hi.

[Elecraft] K2 crystal filter question
Hi all, Just remembered something from my K2 build that I'm still wondering about and never asked on the reflector about. On P54, the 5th step of the build manual: you're instructed to read the number written on the package containing the 7 crystals for the crystal filter. I remember there being such a number on there and writing it down in this step. However, I don't ever recall being asked to use this figure in any of the steps having to do with the crystal filter. Or indeed use that number at all. Unless I goofed up and skipped it somewhere? So my question is, what is this measurement/number ever used for? Just wondering as my K2 seems to work fine and the filters seem to work fine too...

Re: [Elecraft] K2 crystal filter question
LS, That number is ignored in the base K2 manual, but if you add the KSB2 board, the number that is printed on the crystal set for that option is important to initially set the SSB filter passband right. If you just used the default values for your filter, they will be close, but you will find an improvement if you refine the filter alignment. It is not difficult, and there are several methods, but bite the bullet and use Spectrogram. Go to my website www.w3fpr.com and read the article on K2 Dial Calibration. Part 3 of that article deals with the filter setup, and has links and references. You can download version 5 of Spectrogram (it is freeware) from www.n0ss.net. Note that it is no longer available at Visualization Sofrware's website. 73, Don W3FPR lstavenhagen wrote: Hi all, Just remembered something from my K2 build that I'm still wondering about and never asked on the reflector about.
