The digital signals are only 1% of the analog - IBOC's coverage isn't
even 50% that of analogs !


Digital has totally different properties than analog. I have seen plenty of
data showing the HD signal, on a 3rd generation receiver, is robust beyond
the "usable" signal range of analog AM or FM, which is the 10 mv/m AM curve
and the 64 dbu FM contour.
