[TenTec] Omni Vi and DSP

[Ken Brown]

Hi all,

A question posted on another reflector got me to thinking about the 
built-in DSP in my Omni VI. The only control the Omni VI has for it's 
DSP the NR button which essentially works as an on/off control. It is 
unclear to me, from the narrative description of the DSP operation, 
whether there is any other control to the DSP system which might set it 
for optimum DSP algorithms depending on what mode (CW/SSB/FSK/FM) the 
radio is operating. I suspect that there is no such control, and the DSP 
has just two modes, on and off. Anyone out there know any more about 
these details?

Also I wonder about connecting an external audio DSP unit such as a JPS 
NIR-12. This unit has various front panel controllable functions, which 
presumably could make it work better than a DSP that only runs one fixed 
algorithm, as I suspect the Omni VI's does. Or maybe it would just be 
more knobs to twiddle with no real performance advantage. I suppose if I 
were to try out the NIR-12 with the Omni VI, I would want to get audio 
from the Omni VI BEFORE it has gone through the Omni VI's DSP, and not 
from either the Omni's speaker output or "FIXED AUDIO", which are both 
AFTER the Omni's DSP. I am interested in hearing from anyone who has 
already tried an outboard audio DSP unit with an Omni VI.

Thanks,
