[TenTec] Orion questions

[Greg Fischer]

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.
