[Elecraft] KAT2 - Assy Manual Clarification; Typo's?

[Don Wilhelm]

Paul,

First question:
The most conservative approach is to follow the instructions in the Builders
alert.  During Field Test of the KAT2, A few of us found that the original
method of installing the washers would cause the boards to be too close
together - the BNC connector body was higher than the spacing provided by
the spacers alone.  As I recall, the folks at Elecraft found a different
supplier for the connectors (slightly shorter ones) and the original problem
went away.

If the top of the BNC connectors do not interferwith the spacing between the
boards (causing one or both boards to bow upward), all is OK no matter which
set of instructions you use.

Third question:
Yes, the center conductor is soldered to the RF point and the braid is
soldered to the GND point.

I don't have my manual handy, so I can't comment on your second question,
perhaps others will help.  (Or check the errata sheet to see if it is
mentioned there).

73,
Don W3FPR
