[Elecraft] [K2] DXE Clifton Labs Z10000 Buffer Amp

[Clark Macaulay]

Helps a lot, Jim.

Yes...you answered my question in that you have done it.  So, I'll set
aside a morning where I swear off coffee (steadier hands) and using a new
razor blade give it a try.  Didn't know the cable in the kit is RG178 which
is about 30% smaller than RG174.  I don't see anyplace on the board to tack
on a RG174 cable as the pads for the SMT components are so small.  It's
actually a beautiful board.

For anyone who stumbles on this thread, I'm not being critical of the DXE
kit.  Nor am I inexperienced in building stuff (several QRP radios
including the K2).  Looking at the size of the cable, I'm not at all sure I
can make this happen.  I really do want the buffer amp installed in my K2.

Nothing ventured, nothing gained so say the sages.
