K1 BUILD ISSUES

[KENT TRIMBLE]

The following two issues arose during a K1 build that, while obvious to
some, weren't to me, and probably wouldn't be to many . . .

(1)  Even though the Errata sheet says trimmer caps C13 and C20 "may
look different from what is shown", the trimmer caps shipped with recent
K1 kits not only look different, they are structurally different in that
they have no "flattened" side which is the indicator for how they are to
be mounted.  However, continuity testing between the tuning slot (the
metallic tab that the screw driver turns) and each contact leg will
reveal that the leg with the continuity is the same as the "flattened"
end.  I would have guessed it was the leg with the dab of red paint but
I would have been wrong.

(2)  At first I thought I was missing eight 0.1mf capacitors said to be
labeled "104."  A strip of eight, blue, square components with no "104"
was remaining in the RF board bag, and I eventually surmised they
constituted the missing capacitors, although they looked different from
any capacitor I had ever seen in my 58 years in the hobby.

My thanks to Don Wilhelm for saving me a lot of extra work.

Suspecting the K1 and K2 kits are probably not long for this Earth, I
bought both last Fall with the intent of building the K1 this Spring and
the K2 this summer.  A close friend talked me out of my KX1 a while back
which, for some reason, resurrected an urge to build again.  I've built
all the mini-modules and the big rigs, but screw-driver assembly isn't
nearly as satisfying as solder-assembly.

Kent and all,

The K1 needed to be discontinued because the enclosure metalwork was no
longer available, and the cost for a new vendor to tool up was prohibitive.

OTOH, the K2 is around and selling for just as long as possible.
Procurement of thru-hole components becomes more difficult as
manufacturers are switching to all SMD components.  So far Elecraft has
been able to provide suitable substitutes such as the SA612 IC mounted
on a carrier board so it can be used in a thru-hole board.  Other such
substitutions will be coming in the future, but Elecraft is dedicated to
keeping the K2 kit alive for as long as possible.
