Starting today, September 17, the folks at WAMU FM in Washington, DC will broadcast their 24/7 online bluegrass audio channel as an HD FM radio signal as well. DC area listeners with HD Radio receivers can find the new channel at 88.5-2.

Folks without access to HD radio will notice that many of their favorite bluegrass and acoustic music programs are no longer being carried by WAMU’s FM broadcast, but station management is betting that the future of radio involves this sort of niche programming, and that its home will be with HD Radio.

BluegrassCountry.org has more details about the change, as does a piece in yesterday’s Washington Post.
