I'd also increase transmitter power.
I hope this never happens, my collection of working antique radios will become doorstops if it does. I prefer analog audio wherever possible...My ear can average away analog noise, but digital breakup/dropout can not be averaged away so easily...
Audio quality has a lot to do with RX design. There is analog AM HiFi stereo, and it's audio quality can approach that of a decent FM RX. Most newer AM radios don't bother to design for good audio quality since they assume AM is talk only and need only sound as good as an 80's POTs phone line... Many modern FM tuners are rather halfassed too...If you listen to a high end tube or early SS rig from the years when top 40 AM was king, and classic music audiophiles were the FM market, and demanded that FM sound perfect you will never want digital.
