The manual calls for this to be greater than *100* ohms, not *100,000* ohms.
A kit sold for 14 years is unlikely to have incorrect test point standards. :-)

I have wished (for 14 years) for such PCB trace layouts.  They are very
appropriate for *ALL* kits.  For some reason that has never been coherently
explained, Elecraft has never supplied them.  Tom/N0SS (SK) published photos
of the PCB for the K1 years ago, but I do not think those are available any
more, even at the remnant of his web site that is preserved by his ham club.

Hi,

Yes, Tom had scans of all the legacy gear boards, both top and bottom.
They were on the preserved website at http://www.mmccs.com/mmarc/n0ss/,
but right now, it looks like the link refers back to the master page.  I
will try to contact their webmaster to see if that can be fixed.

In the meantime, I do have copies of those board images, and will email
them one at a time to anyone who requests them.

73,

You mean this link for N0SS signal tracing on the K1?

http://www.mmccs.com/mmarc/n0ss/k1_signal_tracing.pdf

Mid-Missouri radio club continues to maintain most of Tom’s papers.
