Reception: there's what a Walkman can get but also consider car radios, home, etc You may have better luck with those. When people started talking about 97.7 as a poss. home for EEI, I tried it in my car at places like Endicott St Danvers, Rt 62 Beverly...it did come in. A Walkman or an mp3 player or portable HD radio which has FM might do well dep. on the brand.
With all the electronics around, AM or even FM recep. can get jammed, but esp. AM and as has been said some people have FM only on their mp3 players-with-radio (the HD radio port. would give you EEI, BZ, or poss 1200 via sub-signals but who knows if you'd get them if you aren't close to town)
As for 50kW signals that might be abandoned with a move to FM, they could be sold perhaps even to
outfits in town like Greater or CBS or CC if they think money could be made with who knows what
format. Ha, if RKO moved to FM, Jeff Santos could buy 680 for a song and put prog talk on

Or Entercom could keep it and run oldies--RKO on FM does talk while 60s, 70s, 80s oldies go on
