Thanks George. This does seem to be the consensus. Would be nice if the DSP was affective at all levels and bandwidths. Such is the nature of the beast I guess.

It is interesting to watch the spectrum of receiver noise output change as
you invoke NR in various degrees of aggression. My experience would echo
yours, Jerry. Also I find that signal level to an external device has a
bearing on how well it works, viz, my NIR-12.
