[Elecraft] K2 Update Process?

[Don Wilhelm]

Bill,

Go to the Elecraft Order page on their website and surf to the K2 Spare 
Parts and Mods section.  From there, your point of interest is the K2 A 
to B mods.  Order all within that A to B list and also order the 
K2KEYMODKT.  That will get your K2 up to date.  Since there was a change 
in the crystal specs that occurred at SN 2560, I also recommend that you 
order the set of 14 matched crystals (if you do not have the KSB2, you 
only need the set of 7).

73,
Don W3FPR
