    Frank, have you considered that NB is for impulse noise and not general atmospheric noise? And as for ANF, mine seems to work fine at release 1.6.x.   Some have complained it causes audio distortion but it really does notch out any offending carriers.      73 Amici Mia,       Jim

    I also find NR, WNB and ANF vastly superior to what they were a few versions ago. I find playing with AGC for optimal Signal to Noise Ratio paramount to get good results.

    Yes, I should have mentioned AGC-T which is very effective in noise reduction.     Jim

    AGC-T is great. You just have to hit the sweet spot.  It's been that way since PowerSDR. 
    AGC-T does not solve the ANF problem however on SSDR. Toggling on ANF causes audio distortion and the carrier is audible behind any voice intelligence.  It's only silenced when there is no voice intelligence.

    Steven, maybe I think mine works great because I have no high frequency hearing.  HI HI.           73, Jim
