That's a good question, but I think a lot of the answer is found in the various set-ups of verious radios. With the Superhet formula (antenna, r.f. amp, converter, i.f amp, detector, a.f amp then loudspeaker) signals are boosted to pretty sensitive levels. I'm not quite sure how it's done with solid state.
