Hi Ron,
What you described is the way I have been using the v2.xxx NR since day one
(rcv'd OII 12/29/05). Changing the NR value seems to adjust the amount of
expansion, and with the rf gain, the user can set the threshold. And I find it
helps a lot. Also with SSB, but not as much for obvious reasons. Is this also
your impression?
73,
