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.
