[TenTec] OMNI VI+ audio

[Rob Atkinson, K5UJ]

Part of the success with the Omni VI rx audio has to do with what the 
station you are listening to is transmitting.  If you are copying a station 
that is txing at your rx bandwidth capability, he's going to sound "normal." 
  The Omni VI is an analog bandwidth limited rig--the dsp is used for rx 
noise reduction.  For what it was designed for, mostly dxing and contesting 
like the FT-1000D, it is fine.  The move to the wider INRAD 2.8 KHz filters 
with the smoothing filter ripple mod will offer noticeable improvement but 
no matter what you do you are still limiting yourself to receiving mostly 
mid-range audio frequencies.  My experience listening to the hi-fi audio 
guys with mine opened to 2.8 KHz was some puzzlement--they sounded okay but 
also rather anemic.  As others have reported, my experience was 
underwhelming.  I simply did not realize I was only getting their mid-range. 
   I think this accounts for most of the, "I don't get what's so great about 
this hi-fi stuff" comments.
I finally began listening on a SSB rx opened up to 6 KHz; the difference was 
almost incredible, like (if you are old enough to have experienced this) 
watching B&W tv for years and years and then getting a color set and seeing 
all the shows in color for the first time.   When color tv was new everyone 
used to say after you have had one for a week or two you won't be able to go 
back.  Same with this--after a week or two of hearing all the high and low 
frequencies in addition to the mid-range you won't want to go back to < 2.8 
KHz.
