[Elecraft] K2 Options - when?

[Chris Kantarjiev]

I've just added KNB2, KSB2 and KAT2 to s/n 3641, a basic CW K2.

KNB2 requires access to the top and bottom of the RF board - easy,
just the top and bottom cover.

KSB2 requires the same access - some of the work is a little more
crowded (just like the KSB2 itself). It *also* requires that you
add some components to the front panel board (and, while you're in
there, ground the mic jack, too!).

KAT2 requires that you remove the heat sink, which means fiddling the
PA transistors. You might want to put the aux RF connector in now,
if you have it already.

None of it was at all difficult.
