Folly or Futurist? A top Hubbard Broadcasting engineer places his bets on HD Radio for an AM lifeline. For many across the radio broad- casting industry, the concept of “AM revitalization” — as championed by FCC Chairman Ajit Pai — has little to do with any enhancement, improvement or upgrade of an existing kHz-based facility. Rather, the focus has been on that 250-watt FM translator designed to bring a bigger audience to a station on what many consider to be a dying broadcast band. That’s the branding associated forlorn simulcast of programming based In some countries, where AM was with the most eclectic Adult Album at the 1500 kHz signal that had once been defined as “Medium Wave,” all radio sta- Alternative radio station you’ve likely the home of WTOP and then the home of tions were permanently silenced and their ever heard, based at Class B WWFD-AM The Washington Post Radio Network and programming shifted to DAB. 820 in Frederick, Md.

Spotting the booth for Xperi, now the purveyor of HD Radio, he walked up, introduced himself, and noted that he wanted to take one of his stations all-digital — WWFD. He asked for help. “After the stunned reaction, a lot of planning and coordination, engineer- ing and antenna system modifications were done over the next year,” Kolesar says with a laugh.
