[Elecraft] Upgrade question

[Don Wilhelm]

Jim,

I forgot to mention - for all K2s with serial numbers less than 2560, 
replace the IF crystals too - the filter will improve dramatically.  A 
set of 7 matched crystals is only $10 from Elecraft and if the KSB2 is 
installed, a set of 14 matched crystals is only $15.  There is no need 
to match the KSB2 crystals to that used in the K2 IF filter, 2 matched 
sets of 7 crystals will work nicely too (if you purchase a KSB2 option, 
you will receive a matched set of 7 crystals with the kit.

73,
Don W3FPR
