HD-AM has problems, but I'm a fan of HD-FM. The subchannel and other real-time data uses will make it worthwhile in the long term, IMO.
Plus, it does sound better, more often than not. But it's up to individual stations to have it processed correctly.
The rabid anti-HD crowd is a bunch of Kool Aid drinkers. Mostly old geezers who are mad about AM DX, and the interference it causes. However, I'm not saying they don't have a point, just that they lump FM in with it.
I would be willing to sacrifice HD on AM if they leave FM alone.
As for having a HD radio locally (meaning, WV), I have one in my car, and it's really not worth it at this point, unless you do some traveling to major markets. That's where the action is.
Speaking of, when are you Charleston stations gonna stream some text? All I ever see is " / / ".
