It may not be easy to do hardware wise, but just shifting the sample 
rate to fit ones bandwiidth (FFT size and resolution, ...) of interest 
seems ideal to me. This is often a problem in biological acoustics for 
example because one needs a wide variety of bandwidths for different 
species from blue whale to bat, but A/D cards are made at specific 
sample rates often not quite meeting the requirements of bandwidth and 
resolution ... no doubt similar problems exist in the electromagnetic 
spectrum.
