I'm running 3.27/2.25 on K3 #569, mostly CW. No EQ, default AGC settings. The NR is so improved (for CW at least) with this version that for the first time I'm tempted to actually use it!. Normally I simply reduce DSP BW to overcome noise when working the weaker CW signals, but like to use a relatively wide BW when tuning around or copying the stronger signals. Yes, a filter is a filter but the NR artifacts are so minimal now that I can leave the BW at 800 Hz or so (I have the 1kHz roofing filter) and just turn on the NR ( I also like F1-3) if the band noise becomes too great. Give it a couple of seconds to converge and the noise vanishes yet all but the very weakest signals in the passband remain, with minimal distortion.
