[Elecraft] K2 mod questions

[N2TK, Tony]

I am ready to start Assembly Part III of my #3481 K2. So far, everything is
going fine.
I have the following options to build that I will be adding - KPA100,
K160RX, KNB2, KSB2, KDSP2.
My question - what mods should I consider for this serial number? Are the
following recommended? Any others?
K2 Control Board - R17 - change from 3.3M to 1M to operate QSK above 16WPM
K2 RF Board - for 160M - Change C13 and C14 from 1200pf to 2200pf.
KSB2 - KI6WX 2.5KHZ SSB mod.
Should these be done during initial assembly?

Tnx
Tony
