AM stations that run IBOC must run an even more limited
frequency response on their analog signals than stations
that don't, and they don't change that processing even
when they aren't running IBOC at night.

When WBZ first turned on the IBOC a few years ago, there
was a simultaneous sharp drop in their analog frequency
response. It was unfortunate considering what a good
sounding analog AM WBZ once was (though I do have an HD
receiver and appreciate how good WBZ sounds in HD stereo
in the daytime).

It's unfortunate that they don't change their processing
for that special event as long as they're not running
IBOC at night, but they don't.
