UnPCBs (Rework Eliminators) question

[Bruce Beford]

Received my set of UnPCBs earlier this week, and just wanted to say
the quality is as good as I have seen in any board. I have a fully-
loaded QRP K2 (s/n 4444). I bought these to have on-hand, in case I
ever need/want to remove an option module, and keep the radio
operational. These will fit the bill nicely, with a quality product
that will be right at home in my beloved K2.

Now the question. At some point I will probably want to build
another K2, and start with the base model, gradually adding options.
Has a list of parts been made indicating the number/size of female
headers and other components needed to put all the unmodules in a
base K2? I remember seeing an exchange on the Elecraft email
reflector about his, but am unsure if a final tally or list was ever
posted.

I seem to remember mention of 8 or 9 female headers. (I could, of
course simply count the number on the un-modules...) I am most
interested in the other discrete components that are added or
replaced as the options are added. I do remember that a resistor for
the KNB2 was needed. What else? A complete list of any
resistors/caps etc would be handy.

Thanks in advance, and thanks again for a great product!

73,
Bruce, N1RX

Bruce,

I suggest that you download the manuals (or use your existing ones) for each
option and review the installation steps.  The parts lists also show the
part numbers for the headers and standoffs and other parts required.  The
'short' list is as follows:
K160RX - header, standoff and 3 capacitors
KNB2 - header, standoff, 1 resistor
KSB2 - 3 headers, standoff plus parts for the Front Panel board - mic config
header, 5 capacitors, 1 transistor, 1 resistor and 1 R-pack
KAF2 or KDSP2 - 2 headers.

I cannot recommend putting on the RF Board parts for the K60XV until you are
ready to actually install that option because the VFO Range Selection
mechanism is modified although you may want to install the 2 headers, but I
see no gain in doing so because the K2 heat sink must be removed to install
the K60XV and adding the headers at that time is just another easy step.
