Thankyou for the links regarding NR. I hope possibly in future firmware updates that a signal selection scale will provide more bleed-through at the -1 setting, allowing for a less distorted starting point with better/more audio level.
In addition hopefully the comparison signal selection process algorithms can be improved to better discern noise against audio. After a year with the K3 and experimenting with settings I am happy with the K3 as I have learnt to deal with various signals on various bands. I quite often have local op's telling me they could not hear the station I was talking too. For me having both the 2.1 and 1.8 k 8 pole filters is a plus and I usually listen between 1.8 to 2.1 k width. I use AGC threshold at 8 and slope 0. RX Eq set to N1EU pink noise roll-off settings (red). Some time ago I listened to a USA 40m net on a noisy band. I went through every NR combination with 6-1 giving the relatively best result for NR settings. Then I turned off the NR and turned on the ATT (RF gain already back to 2 o'clock) and what a difference. The noise had become suppressed and transparent, and every weak signal was copied with good clarity compared with the best NR setting I could find, which still sounded like mush in comparison. So I learned using ATT was the way to go. The K3 obviously has plenty of sensitivity to spare. It just makes me wonder how Yaesu's DNR works etc, as it seems very effective without the same issues. Maybe they use a different method?
