Hi Floyd:  Was just following the thread, and checked out you web listing.
Glad I did!  I am a 9050SDX owner and found your comments most useful.
Thanks.

| I think the difficulty here is because the adjustment is again in steps
| of 20.  Mine sounds the closest when LSB is set to -40 and USB is set to
| 20.  I've never gotten any bad reports regarding my SSB audio, but then
| I've not spent much time soliciting comments either.

| I often run the high cut 3-4 notches counter-clockwise to cut the QRM -
| it works as I expect.  When I cut in the 1.8KHz filter, the received
| signal sounds as if the carrier is in the wrong place - the resulting
| audio is too high pitched and devoid of lows.  So, I crank the high-cut
| control 4 notches counter-clockwise again, and the received signal
| sounds perfect.  I've not played with the carrier points to see how that
| affects the 1.8 filter operation.  I'll give that a try.
|
| Several months ago I placed some info I had deciphered from the manuals
| on a web page: http://home.sprintmail.com/~sentek/950tips.htm .  If you
| have anything to contribute to that, let me know and I'll add it.  Maybe
| someone can give us some better guidance on this carrier point
| procedure, and I can add that there as well.
