DSP Filters

If he is talking about NR I agree. I generally don't notice any decrease in background noise when turning on NR and the slider seems to have no impact. AN has been terrible here. I will qualify that with specifics later.... Greg

I have found that the NR does work, but it is pretty subtle at first and takes a little time to "ramp up" the quieting.  It doesn't color the receive audio nearly like what it did in the 1.0.24 beta.  There is some noticeable change with the slider, but that also takes a little while to ramp up.  It is noticeable, but not pronounced.  I would like to see a greater range of adjustment.  But it is a good start, and much improved over the beta.  

ANF it much better than either the 1.0 or the 1.0.24 beta.  The beta made the sound very tinny and would distort on strong signals.  The 1.1 version, again, doesn't color the frequency response nearly as badly and the two previous versions.  

NB works, but by definition doesn't reduce noise traces outside the slice bandwidth.  All noise blankers add distortion, this one also, but careful adjustment allows a happy medium.

What I have noticed is that there is no one, single, setup for these three features that work on all bands, all modes, and all noise situations.  When they fix it for one band/situation/noise type, it seems to be less effective on others.  This is why I would like to see greater ability to adjust various parameters on these functions... perhaps a right click on the buttons could pull up an adjustment window that gives three or four parameters with sliders, adjustment boxes, or number entry boxes.  These could remain persistent by band and/or mode.

Nevertheless, I think the three DSP functions are the best we have seen on SmartSDR so far.  NR could use a little fine tuning, but it is very close.

Just worked FT5 on 160M this morning.  Engaged NR and nada...nothing.  Did not take long to engage cuz nothing happened at all.  Left it on for 5 min and no improvement.

I find much the same as above, i.e. insufficient affect of NR. I've been using my Timewave 59+ to reduce noise in CW and SSB. Currently the 59+ is much better (twice the noise reduction)  than the SSDR NR feature.

Sometimes I find the NR works well and other times I am not sure it is on.  Since my last reset it seems to work most of the time.  I did not have to reinstall anything after the reset.  The NB seems OK though not great...mostly on pulsing noise as I would expect.  It is only active on noise in you filter passband and does nothing to the display, only the audio.  In otherwords with an electric fence on, I still see the pops in the passband, I just don't hear them.  The 5K NB was much more effective as it handled audio and the display.

I have only used v1.1 (just got my 6700) so nothing to compare it to, but I can concur that NR seems to do very little, if anything.  I'm kinda wondering if it does less when "wide" is enabled on the panadapters, but I haven't done much testing on that theory.  I'm happy to try stuff if it helps track down the issue, just let me know.
