Mike,
Do the K160RX first and then add the K60XV is the short answer.
However if you have a high confidence level in your work ...
You can install almost all of both at once if you are careful, and you will
only have to remove the heat sink from the K2 once.
Install all the headers and parts that go under the heat sink in one pass:
If you do not have a 4.7 pf capacitor in your spare parts bin, temporarily
leave out the 4.7 pf capacitor from the K60XV so you have one for initial
testing, othewise build up both option boards.
Do the RF Board additions for both options EXCEPT, do not install D19 and
D20 and do not change C71 as instructed in the K60XV manual.
Replace the heat sink on your K2 and put a jumper between pins 3 and 5 of
J13 (replaces W1). Put the legs of the 4.7 pf capacitor into pins 1 and 3
of J15 (to replace C6 which was removed).
You can now install the K160RX board and complete the testing for that
option.
Now solder the 4.7 pf capacitor onto the K60XV board, add D19 and D20 to the
RF Board, and change C71 to the 120 pf value per the K60XV instructions.
Install, align and test the K60XV and you will be done.
