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.
Ron AC7AC -----Original Message----- 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. -- Bob Baxter AA7EQ Walnut Ridge, Ar. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
