The autonotch is one feature that I have not found to be all that useful with my K3. After this message from Wayne I decided to try it again and find it is better than I last remembered. However, on 75/160m where signals are usually quite strong there is a considerable amount of distortion on the received SSB audio when using the autonotch. On these bands I always have the preamp off and attenuator on plus the RF Gain is dialed back to about the two o'clock position on these two bands.
If I must get rid of a carrier such as from a group of AM ops 2 kHz away, I'll mostly simply adjust the Hi-cut down to 2.05 kHz which usually cuts off enough of the carrier to where it is not objectionable. Otherwise I must use the manual notch and possibly chase carriers from the round table of boat anchors that don't land on exactly 1945 kHz when I am on 1947 kHz. The distortion effect is along the lines of the autonotch aggressively searching for carriers to notch and it trying to suppress voice peaks. Perhaps the algorithm could be tweaked to lengthen the time the autonotch uses to determine a sine wave carrier as opposed to a voice peak. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.
