Assuming this law passes, the FCC should use those 8 years to modernize the EAS system and use something other than commercial AM radio stations as its backbone.
(Read the next paragraph
before laughing at this one.

) What about also using those 8 years to expand the FM band downward (into the low VHF TV region) while simultaneously licensing all existing AM broadcasters to simulcast within that new FM spectrum -- with the goal of getting all of them off their existing, range-and-wattage-shoehorned, suboptimal FM translator frequencies, and off
most of their legacy AM frequencies, by the end of that same 8 year period?
Yes, I know very few members of the public will ever buy new hardware radios again, even for something like expanded FM coverage. However, I am wondering if the
car radios in most modern automobiles haven't actually been
SDR-based for a very, very long time now. If so, couldn't simple firmware updates automagically back-install expanded FM coverage into a huge percentage of cars on the road today? This would almost certainly be possible if automakers have been using
cookie-cutter SDR chipsets all along -- chipsets internally compatible with the international 66-108 MHz master range yet software settings-limited to tuning only subsets of that master range appropriate to each different country or region.
If magically back-installing expanded FM into a large percentage of existing cars were actually possible, and if it were up to me, I would do all the above, plus allow a subset of the existing 50,000 watt stations currently licensed on AM to remain there, acting as radio "superstations." With the AM dial mostly vacant by day as a result, I would also encourage IBOC AM again, at least by day. And any stations staying on AM would still be entitled to licenses for the expanded FM band, so they could also be where most of their local audiences were actually listening. But all these remaining AM signals would continue for the sake of co-channel interference-free national reception at night, plus for groundwave fill-in during the daytime -- and of course for their immense value during long power cuts and other disasters where AM shines as the "information distribution vector of last resort," courtesy its groundwave fill-in and skywave properties that FM and cellular cannot match.
