Just for the sake of debate, maybe we shoud discuss: Is the FCC asking the wrong question?
In Metro areas, it makes little difference to the COMMUNITY whether the AM band survives. (It makes a lot of difference to the current owners of AM properties.)
I would propose that the proper FIRST question is "What does the FCC see as the role of radio in small markets, rural markets." Maybe moving the AM stations there over to FM is the answer. So how do they come up with FM frequencies to serve the "boonies".
Class A FMs were originally limited to 3kw. But small market folks saw the dollar signs and wanted 6kw so they could reach into metro markets, or sell to people wanting to reach into metro markets. Many smaller communities under the umbrella of metro markets were left "stripped naked" or at best left with an AM daytimers.
Looking back over our shoulder, maybe they should have reduced Class A to 1.5kw, made more of them available by reworking the allocation tables, and given all Class A stations with more than 50% of the population coverage withing metro areas 48 months to move further out.
Are my suggestions likely to gain any traction in today's climate? No. Will any plan the FCC comes up with to revitalize the AM band likely gain traction, and solve anything? Probably not.
