[Elecraft] SSB audio problem

[Ron D'Eau Claire]

Transmit, receive, or both? 

If on receive, that vintage of K2 needs the 2nd XFIL flattening mod as the
first step. It takes out the "tilt" in that filter (used only on receive)
that makes the audio sound bassy on one sideband and tinny on the other.

My K2 #922 ssb audio has a very pronounced sibilance problem (like a
lisp).  The amount varies with different people speaking.  SF4 (dsp)
will cancel it out but that affects intelligibility, and I don't have
that much to spare.  SF1-3 don't have much effect on it and turning
the dsp off doesn't help.  I don't know how long this has been going
on as I haven't used ssb for a few years--I have a 50 pound Kenwood
that does ssb pretty well if I feel the need for it.  I haven't done
the matched crystal mod and I'm wondering if that will help.  Any
ideas will be appreciated.
