[Elecraft] Installing KSB2

[Don Wilhelm]

Phil,

The KSB2 installation requires only the removal of one capacitor and two
wire jumpers from the RF board.  The hard part is disassembling the front
panel to install the parts for the microphone input, but no de-soldering
there.

The K160RX requires only the removal of one jumper - all the rest are added
capacitors

The KNB2 is the 'hardest', it requires removing one jumper and 3 resistors.

IMHO, the potential problems with 'rework eliminators' (making an eror or
forgetting to install the RW boards when testing) exceed the benefit gained,
but your mileage may vary.

The rework eliminator that really complicates things is the one for the
K60XV.  I do not recommend installing any parts for that one until you have
the K60XV option in hand.  Your K2 VFO range cannot be correctly tested if
you install the parts and do not plug in the K60XV option itself.

73,
Don W3FPR
