[TenTec] Orion NB vs NR

I've been complaining about the poor audio. Eating some crow, and with 
thanks to Merle Bone who pointed this out, I hadn't read the manual 
correctly that the hardware NB is an off/on switch. So that's fixed and 
the NB works fine.

On to NR. Listening to A61Q this AM on 17 his signal was really weak. 
S-zero weak, but there. I could not copy him using Orion's NR at any 
level. I could copy him with the DSP59+. So I still think the Timewave 
has the edge for very weak signals.

On to strong signals. On 40 this AM the Asian OTH radar was in full 
song. I found a combination of NB9, NR9, and hardware NB took the radar 
out. Maybe not so pleasant to listen to, but made the 40 CW DX window 
usable. As others have pointed out, there's no one setting that covers 
it all.

Thanks to the many folks who have participated in this discussion. For 
me, back to the AGC discussion.
