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,
