[Elecraft] Resend: K2 Addons - now or later?

[Don Wilhelm]

Ron,

>From a technical (i.e electrical) standpoint, it doesn't make any difference
at all.
>From a physical standpoint, the K160RX and the K60XV require removal of the
heat sink, so you may want to minimize the number of times the heat sink is
removed.
>From an alignment standpoint, the KSB2 and the K160RX will influence the
base K2 alignment (and possibly the K60XV - but I am not sure on that one),
but all the others are add-ons and will not influence the settings
established for the base K2.

There IS a benefit in doing the alignment several times (bandpass filters
and CAL FIL primarily) - after operating the K2 for a while, you will
develop your personal preferences for filter bandwidth, sidetone pitch, etc.
And by planning to do that alignment several times, you will end up with a
K2 that better suits your needs and preferences.

Bottom line - it really doesn't matter a whole lot.
