[Elecraft] K1 BUILD ISSUES

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.
