Here in Vegas, the local NPR group is the only people who know how to use HD Radio. They have two stations, and both are simulcasting three stations. Their own station, the other station, and a third station. so the NPR Talk station is also broadcasting a mirror of classical along with even more news and talk, while the Classical station is mirroring main NPR talk along with Xponential Radio, whatever that is. I like some of the HD2s, but I don't get to listen to them much.
