I found this interesting passage in "Radio's Digital Dilemma":

I wonder if anyone ever followed up with Mr. Franzen to get his review of the radio and to see what became of it. That was before FM HD multicasting (HD2/HD3 channels) was implemented, so if he remained an HD Radio listener, he probably soon replaced it with a newer multicasting-capable model.

it was not until January 5, 2005 that Nathan Franzen of Cedar Rapids, Iowa became the first person in the U.S. to purchase an HD Radio receiver. The event made headline news in both Radio World and Current.
