Dave,
You will have to mount the headers (2 pin) for the AUX RF and the AUX
12V on the RF Board unless you have already done that (none of your
current options require those).
Your current QRP K2 has a serial number less than 3000 -- You will also
have to make the mods on the Control Board for the sidetone source/TXD
from U6 pin 25 - again, this might have been done The instructions are
in the KPA100 manual.
Oh yes, you will also have to remove pin 4 from the Control Board header
that the KPA100 ribbon cable plugs into.
Other than that, you should not have to do anything other than the
mechanical swap.

G'day to all,
I have a couple of K2s that I would like to exchange options in and am
wondering just how involved it would be. I did not build either of these radios
initially.
Here are the two radios:
K2/10 S/N 02689 with KSB2, K160RX, K60XV, KNB2, KAF2, KAT2
k2/100 S/N 3523 with KSB2 ( I have KNB2, K160RX and KAF2 kits to install )
What I would like to do is pull the KPA100 out of the one radio and make what
is currently the QRP radio a K2/100. I'd like to know if there is anything to
be aware of or reasons that this might be a bad idea. How difficult of as
project would this be?
Tnx es 73,
Dave N8AG
