There would be no audience statistics that showed whether night HD was
good
or bad, just as there are none for daytime operation.- Hide quoted

There are no listener or audience statistics for radio stations? How
in the world do radio stations determine market share, sell
advertising, etc., then?

The effect of HD can not be measured; radio ratings vary considerably due
to
competitive situations, the normal statistical wobble or error of a poll
and
there is no way to tell which reason of many is affecting ratings. Since
the
HD1 channel of every FM is a simulcast of the analog channel, there is no
way to distinguish it from the analog product in the ratings; AM has no
secondary channels so there is going to be no difference in ratings for
an
HD or non-HD station. So far, in this early stage, there is no
measurement
of HD 2 channels although in the People Meter, such channels will encode
for
Arbitron separately and will then be measurable.

The point isn't trying to use statistics to point a finger at HD, but
rather to use them to determine whether the channels are attracting a
sufficient audience. That's all those numbers are really good for.

The main purpose of FM HD is to provide digital main channel audio and
robust texting; the digital audio is the only enhancement for AM of
significance. Simulcasts are not measured separately in radio ratings.- Hide quoted text -

And what reason do we have to think you're telling the truth THIS time?
