A new survey from Mark Kassof & Co. reveals that five percent of 18- to 64-year-olds think they are receiving HD Radio from at least one of the FM stations they listen to, but have not actually purchased an HD receiver. Among those who say they are receiving HD radio but haven't purchased a receiver for it, 46 percent say it is "about the same" as regular FM radio, while 12 percent say it is "a lot better" than regular FM.

Mark Kassof explains that, "Stations contribute to confusion when they say they are 'broadcasting in HD' without offering an explanation of what HD provides and what is required to receive it. As a result, some listeners wrongly think they are receiving HD."

Meanwhile, one percent of people in the survey say they have purchased an HD radio, and two-thirds of them say HD is "a lot better" than regular FM. The findings were based on 752 telephone interviews completed from September 13-17 in the U.S.
