Application Note: Calibrating the K2's 4 MHz Master Oscillator

Eric Swartz - WA6HHQ

Here's a technique that allows C22 (K2 Master Oscillator Calibration
Capacitor) on the K2 Control Board to be set to precisely to the correct
position, with no guesswork, and no external test equipment.

We've just added this App note to our Builders Page at:
http://www.elecraft.com/Apps/K2info.htm

Look in the 'What's New?' section.

Thanks to Tom Hammond, N0SS, for formatting the app note!

73, Eric  WA6HHQ

Correction - The last 'l' in 'html' was dropped from the original link:

I can't get to that page. I'm told, "That page does not exist on this
site."

The url is correct, except the file suffix is html, not htm.

I think you meant;
http://www.elecraft.com/Apps/K2info.html

Note the .html vs .htm   :-)

Folks,

This IS the "N6KR method" that I have become so fond of (add an 'l' to the
link below).  Wayne was the originator of this method and Tom has done a
good job of documenting it.

I will still stick with my favored method of observing zero beat (looking at
the tone frequencies with Spectrogram) because it takes my ears and eyes out
of the picture and allows me to get within 3 Hz of zero beat.  I realize
that Wayne is trying to achieve a 'no added equipment required' flavor to
it, but for me, the added equipment makes it easier and more certain - YMMV.

I will be updating my webpage (www.qsl.net/w3fpr) with the link to the
document soon.

73,
Don W3FPR
