If you want to talk about radio, where do you post? Here, or General?
A couple years ago, our local FreeFM station was constantly shilling HD radio, boasting of "stations between the stations". ooh what could they be? Considering most of what's on the existing analog stations is entirely crap, why would I want to buy a more expensive radio and get more of the same? I'm only listening to the radio as it is because radios cost $10. If they cost $11, I wouldn't buy one.
Until this thread, I had no idea this technology even existed. It all sounds like a big waste of time. Also, if you paid $10 for a radio, you got ripped off.
It's easier to use the digital radio stations that come with pay TV.
