Naturally, those could stay put. They should be given the option. The other 
possibility is change frequency, perhaps even to a 1'st adjacent, since so many 
of those stations would have vacated... they could end up with more night 
power, easier patterns, etc. Even if they kept the same power/patterns, just the 
migration of all the co and adjacent stations would give them a better 
coverage area at night.

Those should be the "automatic" moves... since they're designed to be "local" 
and non-D, anyway, put them all on the new FM band. I don't think too many of 
them would object too loudly if they had enough "overlap" time to allow 
listeners to get radios (or have existing analog ones modified.)

How many stations on AM are 1Kw or less? Those would be *The Prime Candiates* 
for a move to a new FM band. How much "cleaner" would the AM dial be if, say, 
100% of those stations migrated? Probably quite drastically. Daytimers with 
substantial power could change frequency and keep their original power, only 
now they'd get a substantial night power as well. Or they could migrate to the 
new FM.

It all makes too much sense, technically. If only...
