[Elecraft] K2: 40m bandpass filter

[David Pratt]

Don W3FPR:
A query about C228 a few days ago prompted me to look at my own K2 
manual which does not show C228. Unless my old grey cells deceive me, I 
recall the 40m bandpass filter being changed several years ago. In fact, 
I have found an old envelope in which I have gathered together the 
necessary five capacitors to make the change.

My question is: What was the reason for the change of the 40m bandpass 
filter and is it worth doing?  BTW, I do use my K2 on 60m.
