K3S Receive Settings on WSJT-X

[stengrevics]

I am operating MSK144 on 6 meters.  I have a fairly high noise level which requires use of AGC, NR and NB to get the noise level down on other modes.  But, if I understand correctly, I shouldn't use those features on WSJT-X.  That leaves me with that noise level.  

I would be glad to know what settings other K3S users employ on WSJT-X.

Thanks,

John
