Well, the band is full of HD hiss at night ; and not every HD station
is on HD yet!

In Central Ohio, I left my trusty Sangean HDT1 seeking a HD station, and
it didn't find any. Yet they're audible all over, on a regular radio ;
even very strong ones.

Verdict : you can't hear any HD radio in HD at night, but they're on all over
for the benefit of ordinary listeners, the hiss being better programming
perhaps. Or maybe it's to drive you to some other band that's more
profitable. The commercial profit is in jamming.

You gotta be kidding.
