Re: [Elecraft] K1 BUILD ISSUES

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.

[Elecraft] K1 BUILD ISSUES

2018-04-12 Thread 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.
