Have you ever listened to AM (MW) HD? The voices sound MUCH better
than analog!
It's actually pleasant to listen to. But, they are only HD during the
day, so they're almost useless, except on weekends! That's why WINS
AM is on FM-HD2, so that it can be on all day and night.

But there is so little AM listening at night that it really does not
matter,
business wise.

Broadcasting in the public interest includes the night.

And what interest is served by a band that becomes unused and irrelevant?
Only a few percent of all listeners under 35 ever listen to AM (in other
words, under 10%) and that figure declines every year.

Anyway, younger listeners have chosen to pretty much ignore AM all day, and
the few remaining ones use the band even less at night. This is a listener
decision, not a station one.

Further, a station may choose what listener group it is going to serve,
including by age, sex, ethnicity, etc. Service does not mean serving all
people alike... just some of them.
