[TenTec] Noise Reduction Setting

[K4IA at aol.com]

Amen Emil!
 
And if anyone wonders how good NR "could be,"  load ver 1.371 and give  a 
listen.  That was the last time the NR in the Orion worked and it worked  really 
well.  It was dramatic, almost squelch-like.  
 
My O1 is just back from the factory so I assume it is properly adjusted and  
up to specs.  It is considerably noisier than either my FT1000 Field  or the 
FT2000 I played with at HRO even without any NR used in those  radios.  It 
sounds to me like there is an intermediate stage where the gain  is set way too 
high.  Reducing the RF gain controls and playing with the  threshold does not 
improve the S/N ratio.  Reducing the Bandwidth helps  some but never comes close 
to the clear sounding note in the Yaesus.  
 
Orion's strength is in the implementation of the roofing filters, not its  
DSP.
