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 text -

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.
