[Orion] More ramblings about 2.059d firmware

[Joe Giacobello]

Gary, I have to agree with you.

I originally posted that the NR was working better than ever, but with 
more experience now, I see that it is clipping weak signals badly, 
especially in high QRN conditions.  With stronger signals, it does 
substantially reduce noise and behaves similarly to my the Dynamic Peak 
feature on my JPS-12 audio DSP unit. On weak signals, I have 
experimented with a range of AGC settings without success, but I'm still 
working on it.
