[Elecraft] K3 - auto-notch question

[Bill]

I use the auto-notch a lot - mostly to get rid of the tuner-uppers on 40 
and 75 meters
SSB. It does its job of removing the offending tones well.  However, it 
does introduce a
slight artifact into the received audio. Is there any means to get rid 
of the artifact?

I also use a Kenwood TS-480 (simple and inexpensive rig) as a backup. 
The auto-notch
also works very well on that rig. But.......... the 480 does NOT exhibit 
any artifacts.

Perhaps I have a setting in the K3 done incorrectly - any suggestions?
