[Elecraft] Second Crystal Filter Update

[William Myers]

I'm trying to decide what K2 mods to do on my SN 1760.  Most decisions are
easy - but, I'm not sure about the Second Xtal Filter Flatness mod.

First, I generally follow the "don't fix it if it ain't broke" rule!  I am
looking for some guidance as to if I should do this mod - because my
subjective (read, "operating") reaction is that I've not had the problems
described. However, I'm 99% cw (but I do want the SSB feature to work right
for the other 1%!)

Using Spectrograph, what should I look for to make a proper decision?

Thanks!
