I haven't played with the new NR enough yet but so far I haven't heard any weak CW signals that were lost due to turning on the NR. As long as the signal is still there and the S/N is better I don't mind if the overall volume seems to decrease a little when NR is turned on. The new NR sounds better to me than the old version, but I mostly use a pretty wide filter setting for CW so haven't really tried it with a very narrow filter and weak signal.
One small modification I would like is that when AGC is off and NR is turned on, instead of flashing "N/A" on the display, the NR should simply activate the AGC to the last used setting (Fast or Slow). This is a minor irritation to those of us who frequently jump between AGC-Off and AGC-On: you push NR; it flashes "N/A"; then you have to push AGC and then NR again. NR should just turn on AGC as necessary. (I don't really care whether or not AGC then remains on when NR is subsequently turned off.) 73, Drew AF2Z On Sat, 15 Aug 2009 13:21:19 -0700, Ron AC7AC wrote: >Not just "Q-multipliers" but go back another generation to the regenerative >receiver (or, more properly put, "regenerative detector").
