[Orion] Are AN and NR mutually exclusive?

[John Buck]

Not exactly.

The auto notch  seeks and suppresses continuous tones.  The noise 
reduction tries to identify the characteristic desired signal and 
separate it from background noise.

I cannot think of any reason why they should be mutually exclusive 
unless the dsp processor just cannot handle sufficient calculations to 
do both.

According to the front panel, they are not.  That is, AN on and removing 
a carrier and then when I turn on NR the AN still says on but it is not 
functioning.  Or if NR is on then turning AN on and off has not effect 
except on the front panel.

I avoided using the words mutually exclusive because the NR takes 
priority in the way it seems to be working.

Or 40 meter SSB I love to take out offending carriers while using the 
background noise reduction capability.  No can do with Orion at present.

I doubt that mutually exclusive is an intended feature.  There is no 
such implication in the manual that I can find.
