How about Horton? Or Phoenix?
One of the big issues has been the quadrature, low noise, low spur
clock. Ray was investigating some of this in the Phoenix project, maybe
you could help him with this?.
Maybe a different approach is needed, where we use a non-quadrature
mixer to some IF where a fixed frequency integrating QSD could be
running. The IF filter doesn't have to be 200 kHz wide, it could be
much narrower and still be very useful. In fact, there may be cases
where a much narrower IF filter is really needed!
Or... ???
