    I don’t know how many of you have used the previous SDR sw, Power SDR. But it had a very effective ANF. Wish SmartSDR was as effective. NB does work well on pulse noise. TNF is very very good. WNB is an enigma, still don’t understand what conditions that make it useful.

    I use ANF regularly to notch out the idiots that tune on frequency--works fine. I used the WNB to eliminate noise from a timer. Software version 2.xx.

    I've seen it work on switching power supply and line noise. I don't have any of those anymore but it did work on those.

    The ANF does work for me, but it can distort the audio,,but it does what it should do.

    The ANF notches out a carrier but the carrier comes back as soon as someone transmits. It's modulated by the SSB signal.

    I find I can stop that from happening, it takes careful adjustment. I works well for me.

    What adjustment are you refering to Bill? Moving the ANF slider? I can see an slight improvement on the ANF from earlier versions, but it is not even close to the PowerSDR performance. Maybe I am not using it properly...

    Yes, the slider, I can find a good spot for it and It works well, but still has some distortion in it.

    I guess I got spoiled with PowerSDR. I would leave it ON and not notice it at all. 
    Nowadays I hardly use it, I find the distortion worst than the offending tuner. A TNF is more useful. Problem is when I am using the Maestro... no TNF there.

    I hope they come back to it again. Maybe in V2, I remember it took about 5 years before they got the DSP in PSDR as good as it got.
