Does anyone know of a broadcaster who's turned off their AM HD since
nighttime operation started?

Nobody in Columbus Ohio is broadcasting HD at night, with about 3 stations
with it in the day. WOSU 820 WTVN 610 WCOL 1230 (or whatever they're
calling themselves now).

Actually WCOL might be using it but nobody would be able to tell, at night.
Nobody can hear it.

They should sound killer within 15 or 20 miles of the transmitter.
