Got it
I also found out that PowerSDR only shifts to a 11.025Khz IF in the
DRM mode ... That means I don't have to offset my VFO which simplifies
things considerably ... no more than I use DRM, I can just figure the
offset in my head on the rare occasion I use that mode
Thanks Jean-Claude, Alberto and anyone else that helped me out ...
can't wait to get the finishing touches on my SDR hardware so I can
play with all these really great programs and hopefully use them to
evaluate different circuits for an optimized final version that will
be both software and hardware
