Since my run-in at the NAB Radio Show with industry forces spearheading experimentation with the all-digital AM variant of HD Radio, they have been busy. Back in September, testing was underway on stations in Seattle—the eighth and ninth such stations to conduct tests in the last two years—and the NAB et al. described the preliminary results as quite positive.
When the tests concluded in October, the president of the stations hosting them in Seattle said that while the experience was good, some listeners wondered if their stations would be going all-digital anytime soon. Not for at least 10 years, replied the executive, “because regulatory efforts take time.”
