[Elecraft] K2 Alignment and Verification of Specifications

[Don Wilhelm]

Mike,

Several 'builders for hire' will offer that service for you if you would
like it done for a fee.

The "Facts of The Case" are that you can Do It Yourself.  Follow the
instructions in the K2 manual for peaking the K2 bandpass filters (in
transmit), and set the IF filters using Spectrogram, and you will heve most
all of the critical alignment done.  Expensive and exotic lab instruments
are not required.

The 'critical tool' is Spectrogram.  You can download the last freeware
version form Tom Hammond's website www.n0ss.net, and use the instructions at
Tom's website, the Elecraft website, or the one that I like best, my website
http://w3fpr.qrpradio.com.  All you need to know about aligning the filters
and setting the K2 for accurate dial calibration may be found in my article
on K2 Dial Calibration.  It is not hard to do at all, and when you are done,
you can not only say "I built it", but also say "I aligned it to
perfection".

As I said, there is no 'magic', and there are no exotic tools required.  You
can 'DIY' with a DMM, and the free Spectrogram program running on your
computer - a wideband noise generator is nice to have, but not essential
(see my website article).

Honest folks, that is all there is to aligning the K2 - try it and see,
nothing exotic, just follow the instructions in the manual and use
Spectrogram as a visual aid for the precision filter alignment.

Don W3FPR
