Does NHPR broadcast in HD?

Many of NHPR's frequencies currently broadcast in HD.

The infrastructure we are putting in place will enable us to move to digital channels in the future to provide additional programming choices for our listeners through the HD Radio system. At that point if you want to listen to those additional channels you would have to buy an HD radio. Even then, though, you will still be able to receive our regular NHPR FM signal just like you do now.
